3, 1998. The terms of the New Notes are identical to the terms of the Old Notes
except that the New Notes are registered under the Securities Act of 1933, as

  securities and your ability to transfer them could be adversely affected.
 
- - No public market currently exists for the Notes. We do not intend to list the
  New Notes on any securities exchange and, therefore, no active public market
  is anticipated.
 
INFORMATION ABOUT THE NOTES:
 
- - The Notes will mature on December 1, 2008.
 
- - We will pay interest on the Notes semi-annually on June 1 and April 1 of each
  year beginning June 1, 1999 at the rate of 10 3/8% per annum.

  original aggregate principal amount of the Notes with the net proceeds of
  certain equity offerings.
 
- - The Notes are unsecured obligations and are subordinated to our existing and
  future senior debt.
 
- - The Notes are fully and unconditionally guaranteed on an unsecured senior
  subordinated basis by our domestic subsidiary and our parent holding company.
 
- - If we undergo a change of control or sell certain of our assets, we may be
  required to offer to purchase Notes from you.

THE COMPANY
 
    TRANSDIGM INC.
    8233 Imperial Drive
    Waco, Texas 76712
    (254) 776-0650
 
    We are a leading supplier of highly engineered aircraft components for use
on nearly all commercial and military aircraft. We sell our products to
commercial airlines (such as United Airlines and Continental Airlines), large
commercial transport and regional and business aircraft original equipment
manufacturers (such as Boeing, Bombardier and Cessna) and various agencies of
the United States government. We compete in product specific markets that we
estimate range in size from $10 million to $100 million in annual revenues. For
fiscal 1998, the Company generated net sales, operating income and EBITDA, As
Defined, of $110.9 million, $36.8 million and $43.5 million, respectively.
 
    Our business is comprised of three business units: (1) AdelWiggins Group,
(2) AeroControlex Group, and (3) Marathon Power Technologies Company, each of
which has a long history in the aircraft components industry. AdelWiggins
manufactures an extensive line of fuel and hydraulic system connectors and
specialized clamps, heaters and refueling systems. AeroControlex manufactures
customized fuel pumps, compressors, valves, couplings and mechanical and
electromechanical controls. Marathon manufactures nickel cadmium batteries and
static inverters. TransDigm Inc. was formed in 1993 through a management-led
buyout of the Aerospace Components Group of IMO Industries Inc. In addition,
Marathon was acquired in August 1997 as a strategic complement to the
Adelwiggins and AeroControlex businesses.

BUSINESS STRATEGY
 
    Key elements of our strategy are:
 
- - PROVIDE VALUE ADDED PRODUCTS TO CUSTOMERS. We will continue to focus on
  marketing and manufacturing highly engineered products to customers that place
  a premium on our capabilities. We have effectively communicated to aircraft
  operators that our products will spare them future costs because our products
  are more reliable, perform better and require less maintenance. We can realize
  substantial gross margins on our aftermarket sales (i.e. sales to airlines as
  opposed to original equipment manufacturers) because of our reputation for
  quality and because we are the only supplier for many of the parts that we
  market. We intend to continue to develop and market aftermarket products that
  carry higher gross margins by emphasizing their benefits to customers.
 
- - GENERATE NEW BUSINESS INITIATIVES. In the past, we have successfully
  identified and commercialized new business opportunities to drive revenue
  growth. We have been particularly effective in creating aftermarket
  opportunities by developing superior parts for aircraft already in service.
  New business has contributed significantly to our 14% compound annual net
  sales growth rate (excluding Marathon) since fiscal 1994. We believe that this
  growth rate is well above the industry average during the same period. We
  intend to continue to aggressively pursue growth opportunities through our new
  business initiatives.
 
- - REALIZE PRODUCTIVITY SAVINGS. We will continue to focus on improving our
  operating margins through manufacturing improvements and increases in employee
  productivity. Management has achieved significant increases in productivity
  since fiscal 1994. We have redesigned our business practices and manufacturing
  processes in order to maximize efficiency. For example, we now employ
  performance incentives to encourage our employees to operate multiple
  manufacturing stations in order to minimize overall labor costs. Through this
  initiative and others like it, we have significantly increased sales without
  hiring new employees.
 
- - PURSUE STRATEGIC ACQUISITIONS. We intend to aggressively pursue acquisitions
  that we believe will allow us to enhance value, reduce costs and develop new
  business. The aircraft component industry is highly fragmented, with small
  operators owning many of the companies. We believe that the industry is
  experiencing consolidation due to customer requirements, inherent economies of
  scale and technological advancements that favor more sophisticated companies.
  We completed the Marathon acquisition in August 1997. We regularly engage in
  discussions with respect to other acquisition and investment opportunities.
  See the section "Risk Factors--Risks Related to Potential Future
  Acquisitions."
 
RECENT DEVELOPMENTS
 
    In connection with the offering of the Old Notes, Holdings consummated a
recapitalization pursuant to an agreement and plan of merger. The former equity
holders of Holdings received as consideration in the recapitalization $330.0
million of which $279.7 million was paid in cash, $20.0 million was paid in the
form of Holdings' pay-in-kind notes and Holdings' common stock and approximately
$30.3 million was retained by such equity holders in the form of equity interest
in Holdings.
 
    In connection with the recapitalization, Odyssey Investment Partners Fund,
LLC and its co-investors invested $100.2 million of cash equity in Holdings. As

                   SUMMARY OF THE TERMS OF THE EXCHANGE OFFER
 
<TABLE>
<S>                                   <C>
Securities to be Exchanged..........  On December 3, 1998, we issued $125.0 million
                                      aggregate principal amount of Old Notes to the
                                      initial purchasers (the "Original Offering") in a
                                      transaction exempt from the registration requirements
                                      of the Securities Act of 1933, as amended (the
                                      "Securities Act"). The terms of the New Notes and the
                                      Old Notes are substantially identical in all material
                                      respects, except that the New Notes will be freely
                                      transferable by the holders except as otherwise
                                      provided in this Prospectus. See "Description of the
                                      New Notes."
 
The Exchange Offer..................  $1,000 principal amount of New Notes in exchange for
                                      each $1,000 principal amount of Old Notes. As of the
                                      date hereof, Old Notes representing $125.0 million
                                      aggregate principal amount are outstanding.
 
                                      Based on interpretations by the staff of the
                                      Commission, as set forth in no-action letters issued
                                      to certain third parties unrelated to us, we,
                                      together with Holdings and Marathon (together with
                                      Holdings, the "Guarantors") believe that New Notes
                                      issued pursuant to the exchange offer in exchange for
                                      Old Notes may be offered for resale, resold or
                                      otherwise transferred by holders thereof (other than
                                      any holder which is an "affiliate" of the Company or
                                      the Guarantors within the meaning of Rule 405 under
                                      the Securities Act, or a broker-dealer who purchased
                                      Old Notes directly from us to resell pursuant to Rule
                                      144A or any other available exemption under the
                                      Securities Act), without compliance with the
                                      registration and prospectus delivery requirements of
                                      the Securities Act, provided that such New Notes are
                                      acquired in the ordinary course of such holders'
                                      business and such holders have no arrangement with
                                      any person to engage in a distribution of New Notes.
 
                                      However, the Commission has not considered the
                                      exchange offer in the context of a no-action letter
                                      and we cannot be sure that the staff of the
                                      Commission would make a similar determination with
                                      respect to the exchange offer as in such other
                                      circumstances. Furthermore, each holder, other than a
                                      broker-dealer, must acknowledge that it is not
                                      engaged in, and does not intend to engage in, a
                                      distribution of such New Notes and has no arrangement
                                      or understanding to participate in a distribution of
                                      New Notes. Each broker-dealer that receives New Notes
                                      for its own account pursuant to the exchange offer
                                      must acknowledge that it will comply with the
                                      prospectus delivery requirements of the Securities
                                      Act in connection with any resale of such New Notes.
                                      Broker-dealers who acquired Old Notes directly from
                                      us and not as a result of market-making activities or
                                      other trading activities may not rely on the staff's
                                      interpretations discussed above or participate in the

                                      exchange offer and must comply with the prospectus
                                      delivery requirements of the Securities Act in order
                                      to resell the Old Notes.
 
Registration Rights Agreement.......  We sold the Old Notes on December 3, 1998, in a
                                      private placement in reliance on Section 4(2) of the
                                      Securities Act. The Old Notes were immediately resold
                                      by the initial purchasers in reliance on Rule 144A
                                      and Regulation S under the Securities Act. In
                                      connection with the sale, we, together with the
                                      Guarantors, entered into a Registration Rights
                                      Agreement with the initial purchasers (the
                                      "Registration Rights Agreement") requiring us to make
                                      the exchange offer. The Registration Rights Agreement
                                      further provides that we, together with the
                                      Guarantors, must (i) cause the Registration Statement
                                      with respect to the exchange offer to be declared
                                      effective within 150 days of the date on which we
                                      issued the Old Notes and (ii) consummate the exchange
                                      offer on or before the 185th business day following
                                      the date on which we issued the Old Notes. See "The
                                      Exchange Offer--Purpose and Effect."
 
Expiration Date.....................  The exchange offer will expire at 5:00 p.m., New York
                                      City time,       , 1999 or a later date and time if
                                      we extend it (the "Expiration Date").
 
Withdrawal..........................  The tender of the Old Notes pursuant to the exchange
                                      offer may be withdrawn at any time prior to the
                                      Expiration Date. Any Old Notes not accepted for
                                      exchange for any reason will be returned without
                                      expense as soon as practicable after the expiration
                                      or termination of the exchange offer.
 
Interest on the New Notes and the
  Old Notes.........................  Interest on the New Notes will accrue from the date
                                      of the original issuance of the Old Notes or from the
                                      date of the last payment of interest on the Old
                                      Notes, whichever is later. No additional interest
                                      will be paid on Old Notes tendered and accepted for
                                      exchange.
 
Conditions to the Exchange Offer....  The exchange offer is subject to certain customary
                                      conditions, certain of which may be waived by us. See
                                      "The Exchange Offer--Conditions to Exchange Offer."
 
Procedures for Tendering Old
  Notes.............................  Each holder of the Old Notes wishing to accept the
                                      exchange offer must complete, sign and date the
                                      letter of transmittal, or a copy thereof, in
                                      accordance with the instructions contained herein and
                                      therein, and mail or otherwise deliver the letter of
                                      transmittal, or the copy, together with the Old Notes
                                      and any other required documentation, to the exchange
                                      agent at the address set forth herein. Persons
                                      holding the Old Notes through the Depository Trust
                                      Company ("DTC") and wishing to accept the exchange

                                      participant will agree to be bound by the letter of
                                      transmittal. By executing or agreeing to be bound by
                                      the letter of transmittal, each holder will represent
                                      to us and the Guarantors that, among other things,
                                      (i) the New Notes acquired pursuant to the exchange
                                      offer are being obtained in the ordinary course of
                                      business of the person receiving such New Notes, (ii)
                                      the holder is not engaging in and does not intend to
                                      engage in a distribution of such New Notes, (iii) the
                                      holder does not have an arrangement or understanding
                                      with any person to participate in the distribution of
                                      such New Notes, and (iv) the holder is not an
                                      "affiliate," as defined under Rule 405 promulgated
                                      under the Securities Act, of the Company or the
                                      Guarantors.
 
                                      Under certain circumstances specified in the
                                      Registration Rights Agreement, we may be required to
                                      file a "shelf" registration statement for a
                                      continuous offering pursuant to Rule 415 under the
                                      Securities Act in respect of the Old Notes. See
                                      "Registration Rights."
 
                                      We will accept for exchange any and all Old Notes
                                      which are properly tendered (and not withdrawn) in
                                      the exchange offer prior to the Expiration Date. The
                                      New Notes issued pursuant to the exchange offer will
                                      be delivered promptly following the Expiration Date.
                                      See "The Exchange Offer-- Terms of the Exchange
                                      Offer."
 
Exchange Agent......................  is serving as Exchange Agent (the "Exchange Agent")
                                      in connection with the exchange offer.
 
Federal Income Tax Considerations...  We believe the exchange of Old Notes for New Notes
                                      pursuant to the exchange offer will not constitute a
                                      sale or an exchange for federal income tax purposes.
                                      See "Certain United States Federal Income Tax
                                      Considerations."
 
Effect of Not Tendering.............  Old Notes that are not tendered or that are tendered
                                      but not accepted will, following the completion of
                                      the exchange offer, continue to be subject to the
                                      existing restrictions upon transfer thereof. We will
                                      have no further obligation to provide for the
                                      registration under the Securities Act of such Old
                                      Notes.

                                               New Notes.
 
                                               If we create or acquire a new domestic
                                               subsidiary, it will guarantee the New Notes
                                               unless we designate the subsidiary as an
                                               "unrestricted subsidiary" under the indenture
                                               or the subsidiary does not have significant
                                               assets.
 
Ranking......................................  The New Notes will be unsecured senior
                                               subordinated obligations of the Company and
                                               will rank junior to our existing and future
                                               senior debt. The guarantees by Holdings and
                                               our subsidiaries will be subordinated to
                                               existing and future senior debt of Holdings
                                               and our subsidiaries, respectively. As of
                                               September 30, 1998, pro forma for the
                                               transactions described under the heading "The
                                               Transactions," we and our subsidiaries would
                                               have had $93.1 million of senior debt,
                                               excluding approximately $26.9 million that we
                                               would have had available to borrow under our
                                               New Credit Facility, and Holdings would have
                                               had $113.1 million of senior debt at face
                                               value.
 
Optional Redemption..........................  We cannot redeem the New Notes until December
                                               1, 2003. Thereafter we may redeem some or all
                                               of the New Notes at the redemption prices
                                               listed in the "Description of the New Notes"
                                               section under the heading "Optional
                                               Redemption," plus accrued interest.
 
Optional Redemption after Public Equity        At any time (which may be more than once)
  Offerings..................................  before December 1, 2001, we can choose to buy
                                               back up to 35% of the outstanding Notes
                                               (including New Notes) with money that we
                                               raise in certain equity offerings, as long
                                               as:
 
                                               -  we pay 110.375% of the face amount of the
                                                  Notes, plus accrued interest;

                                                  completing such equity offering; and
 
                                               -  at least 65% of the aggregate principal
                                               amount of Notes issued remains outstanding
                                                  afterwards.
 
Change of Control Offer......................  If a change in control of the Company occurs,
                                               we may be required to give holders of the New
                                               Notes the opportunity to sell us their New
                                               Notes at 101% of their face amount, plus
                                               accrued interest.
 
                                               We might not be able to pay you the required
                                               price for New Notes you present to us at the
                                               time of a change of control, because:
 
                                               -  we might not have enough funds at that
                                                  time; or
 
                                               -  the terms of our senior debt may prevent
                                               us from paying.
 
Asset Sale Proceeds..........................  If we engage in asset sales, we generally
                                               must either invest the net cash proceeds from
                                               such sales in our business within a period of
                                               time, repay senior debt or make an offer to
                                               purchase a principal amount of the New Notes
                                               equal to the excess net cash proceeds. The
                                               purchase price of the New Notes will be 100%
                                               of their principal amount, plus accrued
                                               interest.
 
Certain Indenture Provisions.................  The indenture governing the New Notes will
                                               contain covenants limiting our (and most or
                                               all of our subsidiaries') ability to:
 
                                               -  incur additional debt or enter into sale
                                               and leaseback transactions;
 
                                               -  pay dividends or distributions on capital
                                               stock or repurchase capital stock;
 
                                               -  issue stock of subsidiaries;
 
                                               -  make certain investments;
 
                                               -  create liens on our assets to secure debt;
 
                                               -  enter into transactions with affiliates;
 
                                               -  merge or consolidate with another company;
                                                  and
 
                                               -  transfer and sell assets.
 
                                               These covenants are subject to a number of
                                               important limitations and exceptions.
 
Risk Factors.................................  See "Risk Factors" beginning on page 11 for a
                                               description of certain of the risks you

                SUMMARY HISTORICAL AND PRO FORMA FINANCIAL DATA
 
    The following table sets forth summary historical consolidated financial
information of Holdings and the Company. The summary historical consolidated
financial data for the fiscal years ended September 30, 1998, 1997, and 1996
have been derived from Holdings' consolidated financial statements, which have
been audited by Deloitte & Touche LLP, independent auditors. The summary
historical consolidated audited financial data for the fiscal years ended
September 30, 1995 and 1994, which have also been derived from Holdings'
consolidated financial statements, have been adjusted to give retroactive effect
to the change in accounting for put warrants as described in Note 17 to the
Consolidated Historical Financial Statements of Holdings included elsewhere in
this Prospectus. Because Holdings has no operations of its own and, prior to the
Recapitalization, had no assets or liabilities other than its equity interest in
the Company, the historical consolidated financial information of Holdings for
each of the years in the five-year period ended September 30, 1998 are identical
to the historical consolidated financial information of the Company. The pro
forma financial information set forth below gives effect to the Transactions as
if they had occurred at the beginning of the period or as of the balance sheet
date, as applicable. The pro forma financial information is not necessarily
indicative of either future results of operations or the results that might have
occurred if the foregoing transactions had been consummated on such date. There
can be no assurance that assumptions used in the preparation of the pro forma
financial data will prove to be correct. The Marathon Acquisition was completed
on August 8, 1997.
 
    You should read the following table together with the "Unaudited Pro Forma
Consolidated Financial Information" and "Management's Discussion and Analysis of
Financial Condition and Results of Operations" sections and the Consolidated
Historical Financial Statements and the notes thereto included elsewhere in this
Prospectus.

(1) The Company acquired Marathon on August 8, 1997. The acquisition was
    accounted for as a purchase. The results of operations of Marathon are
    included in Holdings' consolidated financial statements from the date of
    such acquisition. See Marathon's historical financial statements and the
    notes thereto included elsewhere in this Prospectus.
 
(2) Operating income (loss) includes the effect of a non-cash charge of $4,473
    in fiscal 1994 due to a purchase accounting adjustment to inventory
    associated with the acquisition of the Aerospace Components Group of IMO and
    a non-cash charge of $666 in fiscal 1997 and $242 in fiscal 1998 due to, in
    each case, a purchase accounting adjustment to inventory associated with the
    acquisition of Marathon. The $100 adjustment to the Company's 1998 pro forma
    operating income represents the elimination of the advisory fee payable to
    an affiliate of one of the Company's stockholders.
 
(3) In connection with the formation of the Company on September 30, 1993, the
    Company issued subordinated notes which included detachable warrants to
    purchase approximately 16,000 shares of non-voting common stock of Holdings
    at a price of $0.10 per share, exercisable upon certain change of control
    events, including the Recapitalization. The warrant put value adjustment for
    each period indicated reflects the increase in the estimated put value of
    these warrants that occurred during that period.
 
(4) The extraordinary charge in fiscal 1997 relates to costs associated with the
    retirement of the subordinated notes referred to in footnote (3) above
    issued at the time of the Company's formation in 1993.
 
(5) EBITDA, As Defined, represents earnings before interest, taxes, depreciation
    and amortization and the warrant put value adjustments and prior to the
    impact of the purchase accounting adjustments to inventory referred to in
    footnote (2) above and the extraordinary item referred to in footnote (4)
    above as follows:

    Although EBITDA, As Defined, is not a measure of performance calculated in
    accordance with GAAP, the Company believes that EBITDA, As Defined, is
    accepted as a generally recognized measure of performance in the Company's
    industry. Nevertheless, this measure should not be considered in isolation
    or as a substitute for operating income, net income, net cash provided by
    operating activities or any other measure for determining the Company's
    operating performance or liquidity which is calculated in accordance with
    GAAP.
 
(6) For purposes of computing the ratio of earnings to fixed charges, earnings
    consist of earnings before income taxes plus fixed charges. Fixed charges
    consist of interest expense, amortization of debt expense and the portion
    (approximately 33%) of rental expense that management believes is
    representative of the interest component of rental expense. Earnings were
    insufficient to cover fixed charges by $7,630 and $127 for fiscal 1994 and
    1995, respectively.

    THIS PROSPECTUS INCLUDES "FORWARD-LOOKING STATEMENTS" WITHIN THE MEANING OF
SECTION 27A OF THE SECURITIES ACT AND SECTION 21E OF THE EXCHANGE ACT INCLUDING,
IN PARTICULAR, THE STATEMENTS ABOUT THE COMPANY'S PLANS, STRATEGIES, AND
PROSPECTS UNDER THE HEADINGS "PROSPECTUS SUMMARY," "MANAGEMENT'S DISCUSSION AND

ALTHOUGH WE BELIEVE THAT OUR PLANS, INTENTIONS AND EXPECTATIONS REFLECTED IN OR
SUGGESTED BY SUCH FORWARD-LOOKING STATEMENTS ARE REASONABLE, WE CAN GIVE NO
ASSURANCE THAT SUCH PLANS, INTENTIONS OR EXPECTATIONS WILL BE ACHIEVED.
IMPORTANT FACTORS THAT COULD CAUSE ACTUAL RESULTS TO DIFFER MATERIALLY FROM THE
FORWARD-LOOKING STATEMENTS WE MAKE IN THIS PROSPECTUS ARE SET FORTH BELOW AND
ELSEWHERE IN THIS PROSPECTUS. ALL FORWARD-LOOKING STATEMENTS ATTRIBUTABLE TO THE
COMPANY, HOLDINGS OR PERSONS ACTING ON OUR BEHALF ARE EXPRESSLY QUALIFIED IN
THEIR ENTIRETY BY THE FOLLOWING CAUTIONARY STATEMENTS.
 
    FAILURE TO EXCHANGE OLD NOTES--IF YOU DO NOT PROPERLY TENDER YOUR OLD NOTES,
YOU WILL CONTINUE TO HOLD UNREGISTERED OLD NOTES AND YOUR ABILITY TO TRANSFER
OLD NOTES WILL BE ADVERSELY AFFECTED.
 
    We will only issue New Notes in exchange for Old Notes that are timely
received by the Exchange Agent together with all required documents, including a
properly completed and signed letter of transmittal. Therefore, you should allow
sufficient time to ensure timely delivery of the Old Notes and you should
carefully follow the instructions on how to tender your Old Notes. Neither we
nor the Exchange Agent are required to tell you of any defects or irregularities
with respect to your tender of the Old Notes. If you do not tender your Old
Notes or if we do not accept your Old Notes because you did not tender your Old
Notes properly, then, after we consummate the exchange offer, you may continue
to hold Old Notes that are subject to the existing transfer restrictions. In
addition, if you tender your Old Notes for the purpose of participating in a
distribution of the New Notes, you will be required to comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale of the New Notes. If you are a broker-dealer that
receives New Notes for your own account in exchange for Old Notes that you
acquired as a result of market-making activities or any other trading
activities, you will be required to acknowledge that you will deliver a
prospectus in connection with any resale of such New Notes. After the exchange
offer is consummated, if you continue to hold any Old Notes, you may have
difficulty selling them because there will be less Old Notes outstanding. In
addition, if a large amount of Old Notes are not tendered or are tendered
improperly, the limited amount of New Notes that would be issued and outstanding
after we consummate the exchange offer could lower the market price of such New
Notes.
 
    SUBSTANTIAL LEVERAGE--OUR SUBSTANTIAL INDEBTEDNESS COULD ADVERSELY AFFECT
THE FINANCIAL HEALTH OF THE COMPANY AND PREVENT US FROM FULFILLING OUR
OBLIGATIONS UNDER THE NEW NOTES.
 
    The Company has a significant amount of indebtedness. The following chart
shows certain important Company credit statistics and is presented as at
September 30, 1998 and for the year then ended, in each case, on a pro forma
basis assuming we had completed the offering of the Old Notes and the other
Transactions as of the date or at the beginning of the period specified below:

    In addition, Holdings has an additional $20.0 million of indebtedness
represented by the face value of the Holdings PIK Notes (all of which will be
senior to Holdings' guarantee of these New Notes) and, as at September 30, 1998,
on a pro forma basis, Holdings would have had a stockholders' deficit of
approximately $135.4 million. See "Unaudited Pro Forma Consolidated Financial
Information."
 
    Our substantial indebtedness could have important consequences to you. For
example, it could:
 
- - make it more difficult for us to satisfy our obligations with respect to the
  New Notes;
 
- - increase our vulnerability to general adverse economic and industry
  conditions;
 
- - limit our ability to fund future working capital, capital expenditures,
  research and development costs and other general corporate requirements;
 
- - require us to dedicate a substantial portion of our cash flow from operations
  to payments on our indebtedness, thereby reducing the availability of our cash
  flow to fund working capital, capital expenditures, research and development
  efforts and other general corporate purposes;
 
- - limit our flexibility in planning for, or reacting to, changes in our business
  and the industry in which we operate;
 
- - place us at a competitive disadvantage compared to our competitors that have
  less debt; and
 
- - limit, along with the financial and other restrictive covenants in our
  indebtedness, among other things, our ability to borrow additional funds. And,
  failing to comply with those covenants could result in an event of default
  which, if not cured or waived, could have a material adverse effect on us.
 
    See "Description of the New Notes" and "Description of Other Indebtedness."
 
    ADDITIONAL BORROWINGS AVAILABLE--DESPITE CURRENT INDEBTEDNESS LEVELS, WE AND
OUR SUBSIDIARIES MAY STILL BE ABLE TO INCUR SUBSTANTIALLY MORE DEBT. THIS COULD
FURTHER EXACERBATE THE RISKS DESCRIBED ABOVE.
 
    We and our subsidiaries may be able to incur substantial additional
indebtedness in the future. The terms of the indenture do not fully prohibit us
or our subsidiaries from doing so. As at September 30, 1998, on a pro forma
basis, our New Credit Facility would have permitted additional borrowings of up
to $26.9 million and all of those borrowings would be senior to the New Notes
and the guarantees of the New Notes. If new debt is added to our and the
guarantors' current debt levels, the related risks that we and they now face
could intensify.
 
    See "Capitalization," "Selected Historical Consolidated Financial Data" and
"Description of the New Notes" and "Description of Other Indebtedness."
 
    ABILITY TO SERVICE DEBT--TO SERVICE OUR INDEBTEDNESS, WE WILL REQUIRE A
SIGNIFICANT AMOUNT OF CASH. OUR ABILITY TO GENERATE CASH DEPENDS ON MANY FACTORS
BEYOND OUR CONTROL.
 
    Our ability to make payments on and to refinance our indebtedness, including
the New Notes, and to fund planned capital expenditures and research and
development efforts will depend on our ability to generate cash in the future.
This, to a certain extent, is subject to general economic, financial,
competitive, legislative, regulatory and other factors that are beyond our
control.
 
    Based on our current level of operations and anticipated cost savings and
revenue growth, we believe our cash flow from operations, available cash and
available borrowings under our New Credit Facility, will be adequate to meet our
future liquidity needs for at least the next several years.
 
    We cannot assure you, however, that our business will generate sufficient
cash flow from operations, that currently anticipated cost savings and revenue
growth will be realized on schedule or at all or that future borrowings will be
available to us under our New Credit Facility in amounts sufficient
 
                                       12
<PAGE>
to enable us to pay our indebtedness, including the New Notes, or to fund our
other liquidity needs. We may need to refinance all or a portion of our
indebtedness, including the New Notes, on or before maturity. We cannot assure
you that we will be able to refinance any of our indebtedness, including our New
Credit Facility and the New Notes, on commercially reasonable terms or at all.
 
    SUBORDINATION--YOUR RIGHT TO RECEIVE PAYMENTS ON THE NEW NOTES IS JUNIOR TO
OUR EXISTING INDEBTEDNESS AND POSSIBLY ALL OF OUR FUTURE BORROWINGS. FURTHER,
THE GUARANTEES OF THE NEW NOTES WILL BE JUNIOR TO ALL THE GUARANTORS' EXISTING
INDEBTEDNESS AND POSSIBLY TO ALL THEIR FUTURE BORROWINGS.
 
    The New Notes and the guarantees rank behind all of our and the guarantors'
existing indebtedness (other than trade payables) and all of our and all the
guarantors' future borrowings (other than trade payables), except any future
indebtedness that expressly provides that it ranks equal with, or junior in
right of payment to, the New Notes and the guarantees. As a result, upon any
distribution to our creditors or the creditors of the guarantors in a
bankruptcy, liquidation or reorganization or similar proceeding relating to us
or the guarantors or our or their property, the holders of senior debt of our
Company and the guarantors will be entitled to be paid in full in cash before
any payment may be made with respect to the New Notes or the guarantees.
 
    In addition, all payments on the New Notes and the guarantees will be
blocked in the event of a payment default on senior debt and may be blocked for
up to 179 of 360 consecutive days in the event of certain non-payment defaults
on senior debt.
 
    In the event of a bankruptcy, liquidation or reorganization or similar
proceeding relating to our Company or the guarantors, holders of the New Notes
will participate with trade creditors and all other holders of subordinated
indebtedness of the Company and the guarantors in the assets remaining after we
and the guarantors have paid all of the senior debt. However, because the
indenture requires that amounts otherwise payable to holders of the New Notes in
a bankruptcy or similar proceeding be paid to holders of senior debt instead,
holders of the New Notes may receive less, ratably than holders of trade
payables in any such proceeding. In any of these cases, we and the guarantors
may not have sufficient funds to pay all of our creditors and holders of New
Notes may receive less, ratably than the holders of senior debt.
 
    Assuming we had completed the exchange offer on September 30, 1998, on a
pro-forma basis after giving effect to the Transactions, the Notes and the
guarantees by our domestic subsidiary would have been subordinated to $93.1
million of senior debt under our New Credit Facility. In addition, the New
Credit Facility would have provided for up to approximately $26.9 million of
additional borrowings. Holdings' guarantee of the New Notes would have been
subordinated to $113.1 million of senior debt consisting of the guarantee of the
New Credit Facility and the face value of the Holdings PIK Notes. We are
permitted to borrow substantial additional indebtedness, including senior debt,
in the future under the terms of the indenture.
 
    LIMITED VALUE OF HOLDINGS GUARANTEE--YOU SHOULD NOT RELY ON THE GUARANTEE BY
HOLDINGS IN THE EVENT WE CANNOT MAKE PAYMENTS UPON THE NEW NOTES.
 
    The New Notes will be guaranteed by Holdings, our parent holding company, on
a senior subordinated basis. You should not rely on this guarantee because
Holdings has no assets other than our capital stock. If we cannot make payments
under the New Notes, Holdings probably cannot make payments either. In addition,
this guarantee will be subordinated to all senior debt of Holdings (on a pro
forma basis after giving effect to the Transactions, consisting of Holdings'
guarantee of the $93.1 million of borrowings under the New Credit Facility and
the $20.0 million of borrowings consisting of the face value of the Holdings PIK
Notes as of September 30, 1998), whose holders would be paid before you in the
event of a liquidation.

<PAGE>
    DEPENDENCE ON MAJOR CUSTOMERS--OUR COMPANY RELIES HEAVILY ON CERTAIN
CUSTOMERS FOR MUCH OF OUR SALES.
 
    Our three largest customers for the fiscal year ended September 30, 1998
were Aviall (a distributor of aftermarket parts to airlines throughout the
world), Boeing (including McDonnell Douglas) and various agencies of the United
States government. These customers accounted for approximately 20%, 14% and 9%,
respectively, of our consolidated net sales in fiscal 1998.
 
    Our top ten customers accounted for approximately 61% of our consolidated
net sales for fiscal 1998.
 
    The loss of any one or more of these key customers could have a material
adverse effect on our business. See "Business--Customers" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
    CUSTOMER CONTRACTS--WE GENERALLY DO NOT HAVE GUARANTEED FUTURE SALES OF OUR
PRODUCTS. FURTHER, WE ARE OBLIGATED UNDER FIXED PRICE CONTRACTS WITH SOME OF OUR
CUSTOMERS, SO WE TAKE THE RISK FOR COST OVERRUNS.
 
    As is customary in our business, we do not have long-term contracts with
most of our customers. In those cases where we do, for example with Boeing and
the United States government, our customers may terminate these contracts on
short notice.
 
    We also have entered into fixed-price contracts with some of our customers,
where we agree to perform the work for a fixed price and, accordingly, realize
all the benefit or detriment resulting from any decreased or increased costs for
making these products. Sometimes we accept a fixed-price contract for a product
which we have not yet produced, which increases the risks of delays or cost
overruns.
 
    We also have some contracts with customers which establish prices for
certain of our components based upon the volume the customer purchases. A number
of these contracts do not permit the Company to recover for increases in input
prices, taxes or labor costs, although some contracts provide for renegotiation
to address certain material adverse changes. Any such increases are likely to
have an adverse effect on our business.
 
    AIRCRAFT COMPONENTS INDUSTRY RISKS--OUR BUSINESS IS SENSITIVE TO THE NUMBER
OF FLIGHT HOURS THAT OUR CUSTOMERS' PLANES SPEND ALOFT AND TO OUR CUSTOMERS'
PROFITABILITY. THESE ITEMS ARE, IN TURN, AFFECTED BY GENERAL ECONOMIC
CONDITIONS. IN ADDITION, OUR SALES TO MANUFACTURERS OF NEW LARGE AIRCRAFT ARE
CYCLICAL.
 
    We compete in the aircraft component segment of the aerospace industry. This
segment is sensitive to changes in the number of miles flown by paying customers
of commercial airlines ("revenue passenger miles") and, to a lesser extent, to
changes in the profitability of the commercial airline industry and the size and
age of the worldwide aircraft fleet.
 
    Revenue passenger miles and airline profitability have historically been
correlated with the general economic environment, although international events
can also play a key role. For example, in 1991 revenue passenger miles declined
as a result of increased security concerns among airline customers following the
Gulf War. Although 1991 was the only year in the last ten years in which revenue
passenger miles declined, any future reduction would reduce the use of
commercial aircraft and, consequently, the need for spare parts and new
aircraft. During periods of reduced airline profitability, some airlines may
elect to delay purchases of spare parts, preferring instead to deplete existing
inventories.
 
    If demand for new aircraft and spare parts decreases, there may be a
decrease in demand for certain of our products. Therefore, any future decline in
revenue passenger miles, airline profitability or
 
                                       14
<PAGE>
the size of the worldwide aircraft fleet, for any reason, could have a material
adverse effect on our business. See "Business--Industry Overview."
 
    In addition, sales to manufacturers of large commercial aircraft, which
accounted for less than 20% of our annual net sales in fiscal 1998, have
historically experienced periodic downturns. In the past, these sales have been
affected by airline profitability, which is impacted by fuel and labor costs and
price competition, and other things. Due in part to these factors, the number of
large commercial aircraft delivered dropped from a peak of approximately 756
aircraft in 1991 to approximately 370 aircraft in 1995, according to a trade
report.
 
    We believe that by concentrating on products with strong aftermarket demand
and on smaller regional planes, we have reduced our exposure to downturns in
this sector. Prior downturns have adversely effected our net sales, gross margin
and net income. These and certain other factors may cause a downturn in sales to
manufacturers of large commercial aircraft in the future which may have a
material adverse effect on our business.
 
    REDUCTION IN DEFENSE SPENDING--A DECLINE IN THE U.S. DEFENSE BUDGET MAY
ADVERSELY AFFECT OUR SALES OF PARTS USED IN MILITARY AIRCRAFT.
 
    In fiscal 1998, approximately 27.0% of our sales were related to products
used in military aircraft, in each case, over half of which were spare parts
provided to various governmental agencies.
 
    In general, the United States' defense budget has been declining or stable
in recent years, resulting in reduced or stable demand for new aircraft and, to
a lessor extent, spare parts. The United States' defense budget may continue to
decline and sales of defense related items to foreign governments may decrease.
If there is a decline which reduces demand for our components, our business may
be adversely affected.
 
    GOVERNMENT REGULATION--OUR BUSINESS WOULD BE ADVERSELY AFFECTED IF WE LOST
OUR GOVERNMENT PERMITS OR IF FUTURE, MORE ONEROUS GOVERNMENT REGULATIONS WERE
ENACTED.
 
    The aircraft component industry is highly regulated in the United States and
in other countries. In order to sell our components, our Company and the
components we manufacture must be certified by the FAA, the United States
Department of Defense and similar agencies in foreign countries and by
individual manufacturers.
 
    If material authorizations or approvals were revoked or suspended, our
business would be adversely affected. In the future, if new and more stringent
government regulations are adopted or if industry oversight increases, our
business may be adversely affected. See "Business--Governmental Regulation."
 
    To the extent that we operate outside the United States, we are subject to
the Foreign Corrupt Practices Act (the "FCPA"), which generally prohibits United
States companies and their intermediaries from bribing foreign officials for the
purpose of obtaining or keeping business or otherwise obtaining favorable
treatment. In particular, we may be held liable for actions taken by our
strategic or local partners even though such partners are foreign companies that
are not subject to the FCPA. Any determination that we have violated the FCPA
could result in sanctions that could have a material adverse effect on our
business.
 
    RISKS ASSOCIATED WITH OUR WORKFORCE--WE ARE DEPENDENT ON OUR HIGHLY TRAINED
EMPLOYEES AND ANY WORK STOPPAGE OR DIFFICULTY HIRING SIMILAR EMPLOYEES WOULD
ADVERSELY AFFECT OUR BUSINESS.
 
    Because our products are complicated and very detailed, we are highly
dependent on an educated and trained workforce. We could be adversely affected
by a shortage of skilled employees.
 
    At September 30, 1998, approximately 30% of our employees were unionized.
Our collective bargaining agreements expire in April 1999 and November 2000.
Although we believe that our relations
 
                                       15
<PAGE>
with our employees are good, we cannot assure you that we will be able to
negotiate a satisfactory renewal of these collective bargaining agreements or
that our employee relations will remain stable.
 
    Because we maintain a relatively small inventory of finished goods and
operate on relatively short lead times for our products, any work shortage could
have a material adverse effect on our business. "See Business--Employees."
 
    RISKS ASSOCIATED WITH SUPPLIERS--OUR BUSINESS IS DEPENDENT ON THE
AVAILABILITY OF CERTAIN COMPONENTS AND RAW MATERIALS THAT WE BUY FROM SUPPLIERS.
 
    Our business is affected by the price and availability of the raw materials
and component parts that we use to manufacture our components. Our business,
therefore, could be adversely affected by factors affecting our suppliers, or by
increased costs of such raw materials or components if we are unable to pass
along such price increases to our customers. Because we maintain a relatively
small inventory of raw materials and component parts, our business could be
adversely affected if we are unable to obtain these raw materials and components
from our suppliers on favorable terms. See "Business--Raw Materials and
Patents."
 
    POTENTIAL EXPOSURE TO ENVIRONMENTAL LIABILITIES--WE MAY BE LIABLE FOR
PENALTIES UNDER A VARIETY OF ENVIRONMENTAL LAWS, EVEN IF WE DID NOT CAUSE ANY
ENVIRONMENTAL PROBLEMS. CHANGES IN ENVIRONMENTAL LAWS OR UNEXPECTED
INVESTIGATIONS COULD ADVERSELY AFFECT OUR BUSINESS.
 
    Our business and our facilities are subject to a number of federal, state
and local laws and regulations, which govern, among other things, the discharge
of hazardous materials into the air and water as well as the handling, storage
and disposal of such materials.
 
    Pursuant to certain environmental laws, a current or previous owner or
operator of land may be liable for the costs of investigation, removal or
remediation of hazardous materials at such property. These laws typically impose
liability whether or not the owner or operator knew of, or was responsible for,
the presence of any hazardous materials. Persons who arrange (as defined under
these statutes) for the disposal or treatment of hazardous materials also may be
liable for the costs of investigation, removal or remediation of such substances
at the disposal or treatment site, regardless of whether the affected site is
owned or operated by them. See "Business--Environmental Matters."
 
    Because we own and operate a number of facilities, and because we arrange
for the disposal of hazardous materials at many disposal sites, we may incur
costs for investigation, removal and remediation, as well as capital costs
associated with compliance with these laws. Although such environmental costs
have not been material in the past and are not expected to be material in the
future, changes in environmental laws or unexpected investigations and clean-up
costs could have a material adverse effect on our business.
 
    DEPENDENCE ON KEY PERSONNEL--IF WE LOSE OUR SENIOR MANAGEMENT OR TECHNICAL
PERSONNEL, OUR BUSINESS MAY BE ADVERSELY AFFECTED.
 
    The success of our Company is dependent upon our senior management, as well
as on our ability to attract and retain qualified personnel, including
engineers. There is substantial competition for these kinds of personnel in the
aircraft component industry. We may not be able to (1) retain our existing
senior management or engineering staff, (2) fill new positions or vacancies
created by expansion or turnover, or (3) attract additional qualified personnel.
Although we have entered into employment agreements with certain executive
officers, these agreements may not be renewed. See "Management-- Employment
Agreements."

    RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS AND ASIAN FINANCIAL
MARKETS--OUR INTERNATIONAL BUSINESS EXPOSES US TO RISKS RELATING TO INCREASED
REGULATION AND POLITICAL OR ECONOMIC INSTABILITY, GLOBALLY OR WITHIN CERTAIN
FOREIGN COUNTRIES.
 
    Approximately 16% of our fiscal 1998 sales were sold directly to foreign
end-users. In addition, a portion of the products we sell to domestic
distributors are resold to foreign end-users. These sales are subject to
numerous additional risks, including the impact of foreign government
regulations, currency fluctuations, political uncertainties and differences in
business practices.
 
    Foreign governments could adopt regulations or take other actions that would
have an adverse impact on our business or market opportunities abroad.
Furthermore, the political, cultural and economic climate outside the United
States may not be favorable to our business and growth strategy.
 
    The Asian markets are important markets for airlines and the large
commercial aircraft manufacturers. For example, Boeing has developed a large
backlog of aircraft sales to customers in Asia, and the current crisis in the
Asian financial markets has resulted in some deferrals and cancellations of
deliveries. This may result in significant cancellation of orders or additional
deferral of deliveries for new aircraft or negatively impact these
manufacturers. The resulting decreased demand in the aftermarket could adversely
affect our business.
 
    RISKS RELATED TO POTENTIAL FUTURE ACQUISITIONS--WE INTEND TO PURSUE FUTURE
ACQUISITIONS AND ARE CONSIDERING A SPECIFIC ACQUISITION WHICH, IF CONSUMMATED,
WOULD SUBSTANTIALLY INCREASE THE LEVEL OF OUR INDEBTEDNESS AND MAY ADVERSELY
AFFECT OUR BUSINESS IF WE CANNOT EFFECTIVELY INTEGRATE THESE NEW OPERATIONS.
 
    We intend to pursue acquisitions that we believe will present opportunities
to realize significant synergies, operating expense reductions or overhead cost
savings and increase our market position. This acquisition strategy may require
substantial capital, and we may not be able to raise the necessary funds on
satisfactory terms or at all.
 
    We regularly engage in discussions with respect to potential acquisition and
investment opportunities. If we consummate any future acquisitions, our
capitalization and results of operations may change significantly and you will
not have the opportunity to evaluate the economic, financial and other relevant
information that we will consider in determining the application of these funds.
 
    Although we currently have no binding agreements with respect to any future
acquisitions and we cannot assure you that we will be able to reach agreement
with respect to any future acquisition, such acquisitions would likely result in
the incurrence of debt and contingent liabilities and an increase in interest
expense and amortization expenses related to goodwill and other intangible
assets, which could have a material adverse effect upon our business.
 
    Acquisitions involve numerous risks, including difficulties in the
assimilation of the operations, technologies, services and products of the
acquired companies and the diversion of management's attention from other
business concerns. For all of these reasons, if any such acquisitions occur, our
business could be adversely affected.
 
    COMPETITION--WE MAY BE UNABLE TO REPAY THE NEW NOTES IF WE DO NOT
SUCCESSFULLY COMPETE WITHIN OUR INDUSTRY.
 
    We operate in a highly competitive industry and compete against a number of
companies, including divisions of larger companies, some of which have
significantly greater financial, technological and marketing resources than us.
We believe that our ability to compete depends on product performance, short
lead-time and timely delivery, competitive pricing, superior customer service
and support and continued certification under customer quality requirements and
assurance programs. We may not be able to compete successfully with respect to
these or other factors. See "Business-- Competition."

    CONTROL BY ODYSSEY--WE ARE CONTROLLED BY ODYSSEY, WHOSE INTERESTS MAY NOT BE
ALIGNED WITH YOURS.
 
    Odyssey and its co-investors indirectly own approximately 73.7% of the
equity interests in our parent company, Holdings, on a fully diluted basis and,
therefore, have the power, subject to certain exceptions, to control Holdings.
They also control the appointment of management and the entering into of
mergers, sales of substantially all assets and other extraordinary transactions.
The interests of Odyssey may not in all cases be aligned with yours. See "The
Transactions" and "Certain Relationships and Related Transactions."
 
    IMPACT OF YEAR 2000 ISSUE--THE YEAR 2000 PROBLEM MAY RESULT IN DECREASED
SALES FOR US IF CERTIFICATIONS WE RECEIVED FROM OUR VENDORS ARE INACCURATE OR IF
OUR CUSTOMERS AND SUPPLIERS DO NOT ADEQUATELY ADDRESS THEIR YEAR 2000 CONCERNS.
 
    We have completed a review of our computer systems and are completing a
review of our embedded systems in order to assess our exposure to Year 2000
issues. We purchased all of our computer software from third party vendors and
are relying on those vendors to make their software Year 2000 compliant. Except
for the vendor of our e-mail system, such vendors have provided us with third
party certifications that their systems are Year 2000 compliant.
 
    We do not, however, currently have any information concerning the Year 2000
compliance status of our suppliers and customers, including various agencies of
the United States government.
 
    In the event that Year 2000 problems arise within our Company, or that our
significant suppliers or customers, including various agencies of the United
States government, do not successfully and timely achieve Year 2000 compliance,
the result may be a delay in our receiving orders and collecting payments,
leading to a temporary loss of revenue. We have incurred $180,000 in costs
associated with Year 2000 compliance and anticipate incurring $150,000 of
additional costs in the future. We may, however, have to bear further Year 2000
costs and expenses which could have a material adverse effect on our business.
The Company has no formal contingency plan in the event Year 2000 problems
arise.
 
    PRODUCT LIABILITY; CLAIMS EXPOSURE--WE COULD BE ADVERSELY AFFECTED AS A
RESULT OF A LAWSUIT IF ONE OF OUR COMPONENTS CAUSES AN AIRCRAFT TO CRASH AND WE
ARE NOT COVERED BY OUR INSURANCE POLICIES.
 
    Our operations expose us to potential liabilities for personal injury or
death as a result of the failure of an aircraft component that has been
designed, manufactured or serviced by us. While management believes that our
liability insurance is adequate to protect us from future products liability
claims, if claims were to arise, such insurance coverage may not be adequate.
 
    Additionally insurance coverage may not be able to be maintained in the
future at an acceptable cost. Any such liability not covered by insurance or for
which third party indemnification is not available could have a material adverse
effect on our business.
 
    FINANCING CHANGE OF CONTROL OFFER--WE MAY NOT HAVE THE ABILITY TO RAISE THE
FUNDS NECESSARY TO FINANCE THE CHANGE OF CONTROL OFFER REQUIRED BY THE
INDENTURE.
 
    Upon the occurrence of certain specific kinds of change of control events,
we will be required to offer to repurchase all outstanding New Notes. However,
it is possible that we will not have sufficient funds at the time of the change
of control to make the required repurchase of New Notes or that restrictions in
our New Credit Facility will not allow such repurchases. In addition, certain
important corporate events, such as leveraged recapitalizations that would
increase the level of our indebtedness, would not constitute a "Change of
Control" under the indenture. See "Description of the New Notes-Change of
Control."

    FRAUDULENT CONVEYANCE MATTERS--FEDERAL AND STATE STATUTES ALLOW COURTS,
UNDER SPECIFIC CIRCUMSTANCES, TO VOID THE NEW NOTES AND THE GUARANTEES AND
REQUIRE NOTEHOLDERS TO RETURN PAYMENTS RECEIVED FROM THE COMPANY OR THE
GUARANTORS.
 
    Under the federal bankruptcy law and comparable provisions of state
fraudulent transfer laws, the New Notes and the guarantees could be voided, or
claims in respect of the New Notes or the guarantees could be subordinated to
all other debts of the Company or any guarantor if, among other things, the
Company or such guarantor, at the time it incurred the indebtedness evidenced by
the New Notes or its guarantee:
 
- - received less than reasonably equivalent value or fair consideration for the
  incurrence of such indebtedness; or
 
- - was insolvent or rendered insolvent by reason of such incurrence; or
 
- - was engaged in a business or transaction for which the Company's or such
  guarantor's remaining assets constituted unreasonably small capital; or
 
- - intended to incur, or believed that it would incur, debts beyond its ability
  to pay such debts as they mature.
 
    In addition, any payment by the Company or such guarantor pursuant to the
New Notes or a guarantee could be voided and required to be returned to the
Company or such guarantor, or to a fund for the benefit of the creditors of the
Company or such guarantor.
 
    The measures of insolvency for purposes of these fraudulent transfer laws
will vary depending upon the law applied in any proceeding to determine whether
a fraudulent transfer has occurred. Generally, however, the Company or a
guarantor would be considered insolvent if:
 
- - the sum of its debts, including contingent liabilities, were greater than the
  fair saleable value of all of its assets,
 
- - if the present fair saleable value of its assets were less than the amount
  that would be required to pay its probable liability on its existing debts,
  including contingent liabilities, as they become absolute and mature, or
 
- - it could not pay its debts as they become due.
 
    Based upon information currently available to us, we believe that the New
Notes and the guarantees are being incurred for proper purposes and in good
faith and that we, and each of the Guarantors:
 
- - are solvent and will continue to be solvent after giving effect to the
  issuance of the New Notes and the guarantees, as the case may be;
 
- - will have enough capital for carrying on our business and the business of each
  of the Guarantors after the issuance of the New Notes and the guarantees, as
  the case may be; and
 
- - will be able to pay our debts.
 
    NO PRIOR MARKET FOR THE NEW NOTES--YOU CANNOT BE SURE THAT AN ACTIVE TRADING
MARKET WILL DEVELOP FOR THE NEW NOTES.
 
    The New Notes are a new issue of securities with no established trading
market and will not be listed on any securities exchange. The liquidity of the
trading market in the New Notes, and the market price quoted for the New Notes,
may be adversely affected by changes in the overall market for high yield
securities and by changes in our financial performance or prospects or in the
prospects for companies in our industry generally. As a result, you cannot be
sure that an active trading market will develop for the New Notes.

<PAGE>
                                  TRANSACTIONS
 
    In connection with the completion of the offering of the Old Notes, Holdings
consummated a recapitalization of Holdings (the "Recapitalization") pursuant to
an agreement and plan of merger, dated August 3, 1998, as amended, between Phase
II Acquisition Corp. and Holdings (the "Merger Agreement"). Concurrently with
the offering of the Old Notes, the Company entered into a credit agreement
providing for a six-year $30.0 million revolving credit facility (the "Revolving
Credit Facility"), $2.6 million of which was funded to consummate the
Recapitalization, and a 6-year $45.0 million Tranche A Term Loan Facility (the
"Tranche A Facility") and a 7 1/2-year $45.0 million Tranche B Term Loan
Facility (the "Tranche B Facility" and, together with the Revolving Credit
Facility and the Tranche A Facility, the "New Credit Facility"), each of which
was fully funded to consummate the Recapitalization. Additional borrowings under
the Revolving Credit Facility are available for certain permitted acquisitions
and for general corporate purposes, including working capital requirements. See
"Description of Other Indebtedness--The Company--The New Credit Facility."
 
    In connection with the Recapitalization, Odyssey and its co-investors
invested approximately $100.2 million of cash equity in Holdings (the "Odyssey
Investment"). The equity holders of Holdings received as consideration in the
Recapitalization $330.0 million of which $279.7 million was paid in cash, $20.0
million was paid in the form of Holdings' pay-in-kind notes due 2009 of Holdings
(the "Holdings PIK Notes") and Holdings' common stock and $30.3 million was paid
in the form of common stock and options of Holdings that was retained by the
shareholders of Holdings (the "Rollover Investment"). As a result of the
consummation of the Transactions, Odyssey and its co-investors own approximately
73.7%, and certain continuing equity holders of Holdings own approximately
26.3%, in each case, of the outstanding shares of Holdings common stock on a
fully diluted basis.
 
    The offering of the Old Notes, the Recapitalization, the Odyssey Investment,
the issuance of the Holdings PIK Notes and the related borrowings under the New
Credit Facility are collectively referred to herein as the "Transactions."

                               THE EXCHANGE OFFER
 
PURPOSE AND EFFECT
 
    In connection with the sale by the Company of the Old Notes on December 3,
1998, the Company and the Guarantors entered into a registration rights
agreement (the "Registration Rights Agreement"), dated December 3, 1998, with
the initial purchasers, which requires that the Company and the Guarantors file
a registration statement under the Securities Act with respect to the New Notes
(the "Registration Statement") and, upon the effectiveness of that Registration
Statement, offer to the holders of the Old Notes the opportunity to exchange
their Old Notes for a like principal amount of New Notes. The New Notes will be
issued without a restrictive legend and generally may be reoffered and resold by
the holder without registration under the Securities Act. The Registration
Rights Agreement further provides that the Company must (i) cause the
Registration Statement with respect to the exchange offer to be declared
effective within 150 days of the date on which the Company issued the Old Notes
and (ii) consummate the exchange offer on or before the 185th day following the
date on which the Company issued the Old Notes. Except as provided below, upon
the completion of the exchange offer, the Company's obligations with respect to
the registration of the Old Notes and the New Notes will terminate. A copy of
the Registration Rights Agreement has been filed as an exhibit to the
Registration Statement, of which this Prospectus is a part, and this summary of
the material provisions of the Registration Rights Agreement does not purport to
be complete and is qualified in its entirety by reference to the complete
Registration Rights Agreement. As a result of the timely filing and the
effectiveness of the Registration Statement, the Company will not have to pay
certain additional interest on the Old Notes provided in the Registration Rights
Agreement. Following the completion of the exchange offer (except as set forth
in the paragraph immediately below), holders of Old Notes not tendered will not
have any further registration rights and those Old Notes will continue to be
subject to certain restrictions on transfer. Accordingly, the liquidity of the
market for the Old Notes could be adversely affected upon consummation of the
exchange offer.
 
    In order to participate in the exchange offer, a holder must represent to
the Company, among other things, that (i) the New Notes acquired pursuant to the
exchange offer are being obtained in the ordinary course of business of the
holder, (ii) the holder is not engaging in and does not intend to engage in a
distribution of the New Notes, (iii) the holder does not have an arrangement or
understanding with any person to participate in the distribution of the New
Notes and (iv) the holder is not an "affiliate," as defined under Rule 405
promulgated under the Securities Act, of the Company or the Guarantors. Under
certain circumstances specified in the Registration Rights Agreement, the
Company may be required to file a "shelf" registration statement for a
continuous offering pursuant to Rule 415 under the Securities Act in respect of
the Old Notes. See "Registration Rights." For purposes of the foregoing,
"Transfer Restricted Securities" means each Old Note until (i) the date on which
such Note has been exchanged by a person other than a broker-dealer for an New
Note in the exchange offer, (ii) following the exchange by a broker-dealer in
the Exchange Offer of an Old Note for an New Note, the date on which such New
Note is sold to a purchaser who receives from such broker-dealer on or prior to
the date of such sale a copy of this Prospectus, (iii) the date on which such
Old Note has been effectively registered under the Securities Act and disposed
of in accordance with such "shelf" registration statement or (iv) the date on
which such Old Note is distributed to the public pursuant to Rule 144 under the
Act or may be distributed to the public pursuant to Rule 144(k) under the Act.
See "--Procedures for Tendering."
 
    Based on an interpretation by the Commission's staff set forth in no-action
letters issued to third parties unrelated to the Company, the Company believes
that, with the exceptions set forth below, New Notes issued pursuant to the
exchange offer in exchange for Old Notes may be offered for resale, resold and
otherwise transferred by holders thereof (other than any holder which is an
"affiliate" of the Company within the meaning of Rule 405 promulgated under the
Securities Act, or a broker-dealer who purchased Old Notes directly from the
Company to resell pursuant to Rule 144A or any other
 
                                       21
<PAGE>
available exemption promulgated under the Securities Act) without compliance
with the registration and prospectus delivery provisions of the Securities Act,
provided that the New Notes are acquired in the ordinary course of business of
the holder and the holder does not have an arrangement or understanding with any
person to participate in the distribution of such New Notes. Any holder who
tenders in the exchange offer for the purpose of participating in a distribution
of the New Notes cannot rely on this interpretation by the Commission's staff
and must comply with the registration and prospectus delivery requirements of
the Securities Act in connection with a secondary resale transaction. Each
broker-dealer that receives New Notes for its own account in exchange for Old
Notes, where such Old Notes were acquired by such broker-dealer as a result of
market-making activities or other trading activities, must acknowledge that it
will deliver a prospectus in connection with any resale of such New Notes. See
"Plan of Distribution." Broker-dealers who acquired Old Notes directly from us
and not as a result of market-making activities or other trading activities may
not rely on the staff's interpretations discussed above or participate in the
exchange offer and must comply with the prospectus delivery requirements of the
Securities Act in order to sell the Old Notes.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
    Following the completion of the exchange offer (except as set forth in the
second paragraph under "--Purpose and Effect" above), holders of Old Notes not
tendered will not have any further registration rights and those Old Notes will
continue to be subject to certain restrictions on transfer. Accordingly, the
liquidity of the market for a holder's Old Notes could be adversely affected
upon completion of the exchange offer if the holder does not participate in the
exchange offer.
 
TERMS OF THE EXCHANGE OFFER
 
    Upon the terms and subject to the conditions set forth in this Prospectus
and in the letter of transmittal, the Company will accept any and all Old Notes
validly tendered and not withdrawn prior to 5:00 p.m., New York City time, on
        , 1999, or such date and time to which we extend the offer. The Company
will issue $1,000 principal amount of New Notes in exchange for each $1,000
principal amount of outstanding Old Notes accepted in the exchange offer.
Holders may tender some or all of their Old Notes pursuant to the exchange
offer. However, Old Notes may be tendered only in integral multiples of $1,000
in principal amount.
 
    The form and terms of the New Notes are substantially the same as the form
and terms of the Old Notes except that the New Notes have been registered under
the Securities Act and will not bear legends restricting their transfer. The New
Notes will evidence the same debt as the Old Notes and will be issued pursuant
to, and entitled to the benefits of, the Indenture pursuant to which the Old
Notes were issued.
 
    As of the date hereof, Old Notes representing $125.0 million aggregate
principal amount were outstanding and there was one registered holder, a nominee
of DTC. This Prospectus, together with the letter of transmittal, is being sent
to such registered holder and to others believed to have beneficial interests in
the Old Notes. The Company intends to conduct the exchange offer in accordance
with the applicable requirements of the Exchange Act and the rules and
regulations of the Commission promulgated thereunder.
 
    The Company shall be deemed to have accepted validly tendered Old Notes
when, as, and if the Company has given oral or written notice thereof to the
Exchange Agent. The Exchange Agent will act as agent for the tendering holders
for the purpose of receiving the New Notes from the Company. If any tendered Old
Notes are not accepted for exchange because of an invalid tender, the occurrence
of certain other events set forth herein or otherwise, certificates for any such
unaccepted Old Notes will be returned, without expense, to the tendering holder
thereof as promptly as practicable after         , 1999, unless the exchange
offer is extended.
 
                                       22
<PAGE>
    Holders who tender Old Notes in the exchange offer will not be required to
pay brokerage commissions or fees or, subject to the instructions in the letter
of transmittal, transfer taxes with respect to the exchange of Old Notes
pursuant to the exchange offer. The Company will pay all charges and expenses,
other than certain applicable taxes, in connection with the exchange offer. See
"--Fees and Expenses."
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
    The expiration date shall be 5:00 p.m., New York City time, on         ,
1999, unless the Company, in its sole discretion, extends the exchange offer, in
which case the expiration date shall mean the latest date and time to which the
exchange offer is extended. In order to extend the exchange offer, the Company
will notify the Exchange Agent and each registered holder of any extension by
oral or written notice prior to 9:00 a.m., New York City time, on the next
business day after the previously scheduled expiration date. The Company
reserves the right, in its sole discretion, (i) to delay accepting any Old
Notes, to extend the exchange offer or, if any of the conditions set forth under
"--Conditions to Exchange Offer" shall not have been satisfied, to terminate the
exchange offer, by giving oral or written notice of such delay, extension or
termination to the Exchange Agent, or (ii) to amend the terms of the exchange
offer in any manner. In the event that the Company makes a material or
fundamental change to the terms of the exchange offer, the Company will file a
post-effective amendment to the Registration Statement.
 
PROCEDURES FOR TENDERING
 
    Only a holder of Old Notes may tender the Old Notes in the exchange offer.
Except as set forth under "--Book Entry Transfer," to tender in the exchange
offer a holder must complete, sign, and date the letter of transmittal, or a
copy thereof, have the signatures thereon guaranteed if required by the letter
of transmittal, and mail or otherwise deliver the letter of transmittal or copy
to the Exchange Agent prior to the expiration date. In addition, (i)
certificates for such Old Notes must be received by the Exchange Agent along
with the letter of transmittal prior to the expiration date, (ii) a timely
confirmation of a book-entry transfer (a "Book-Entry Confirmation") of such Old
Notes, if that procedure is available, into the Exchange Agent's account at DTC
(the "Book-Entry Transfer Facility") pursuant to the procedure for book-entry
transfer described below, must be received by the Exchange Agent prior to the
expiration date or (iii) the holder must comply with the guaranteed delivery
procedures described below. To be tendered effectively, the letter of
transmittal and other required documents must be received by the Exchange Agent
at the address set forth under "--Exchange Agent" prior to the expiration date.
 
    The tender by a holder that is not withdrawn before the expiration date will
constitute an agreement between that holder and the Company in accordance with
the terms and subject to the conditions set forth herein and in the letter of
transmittal.
 
    THE METHOD OF DELIVERY OF OLD NOTES AND THE LETTER OF TRANSMITTAL AND ALL
OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF
THE HOLDER. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE AN
OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT TIME SHOULD BE
ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT BEFORE THE EXPIRATION DATE. NO
LETTER OF TRANSMITTAL OR OLD NOTES SHOULD BE SENT TO THE COMPANY. HOLDERS MAY
REQUEST THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL BANKS, TRUST COMPANIES OR
NOMINEES TO EFFECT THESE TRANSACTIONS FOR SUCH HOLDERS.
 
    Any beneficial owner whose Old Notes are registered in the name of a broker,
dealer, commercial bank, trust company, or other nominee and who wishes to
tender should contact the registered holder promptly and instruct the registered
holder to tender on the beneficial owner's behalf. If the beneficial owner
wishes to tender on the owner's own behalf, the owner must, prior to completing
and executing the letter of transmittal and delivering the owner's Old Notes,
either make appropriate arrangements to
 
                                       23
<PAGE>
register ownership of the Old Notes in the beneficial owner's name or obtain a
properly completed bond power from the registered holder. The transfer of
registered ownership may take considerable time.
 
    Signatures on a letter of transmittal or a notice of withdrawal, as the case
may be, must be guaranteed by an Eligible Institution (as defined) unless Old
Notes tendered pursuant thereto are tendered (i) by a registered holder who has
not completed the box entitled "Special Registration Instruction" or "Special
Delivery Instructions" on the letter of transmittal or (ii) for the account of
an Eligible Institution. If signatures on a letter of transmittal or a notice of
withdrawal, as the case may be, are required to be guaranteed, the guarantee
must be by any eligible guarantor institution that is a member of or participant
in the Securities Transfer Agents Medallion Program, the New York Stock Exchange
Medallion Signature Program or an "eligible guarantor institution" within the
meaning of Rule 17Ad-15 under the Exchange Act (an "Eligible Institution").
 
    If the letter of transmittal is signed by a person other than the registered
holder of any Old Notes listed therein, the Old Notes must be endorsed or
accompanied by a properly completed bond power, signed by the registered holder
as that registered holder's name appears on the Old Notes.
 
    If the letter of transmittal or any Old 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 so indicate when signing, and evidence satisfactory to the
Company of their authority to so act must be submitted with the letter of
transmittal unless waived by the Company.
 
    All questions as to the validity, form, eligibility (including time of
receipt), acceptance, and withdrawal of tendered Old Notes will be determined by
the Company in its sole discretion, which determination will be final and
binding. The Company reserves the absolute right to reject any and all Old Notes
not properly tendered or any Old Notes the Company's acceptance of which would,
in the opinion of counsel for the Company, be unlawful. The Company also
reserves the right to waive any defects, irregularities or conditions of tender
as to particular Old Notes. The Company's interpretation of the terms and
conditions of the exchange offer (including the instructions in the letter of
transmittal) will be final and binding on all parties. Unless waived, any
defects or irregularities in connection with tenders of Old Notes must be cured
within such time as the Company shall determine. Although the Company intends to
notify holders of defects or irregularities with respect to tenders of Old
Notes, neither the Company, the Exchange Agent, nor any other person shall incur
any liability for failure to give such notification. Tenders of Old Notes will
not be deemed to have been made until such defects or irregularities have been
cured or waived. Any Old Notes received by the Exchange Agent that are not
properly tendered and as to which the defects or irregularities have not been
cured or waived will be returned by the Exchange Agent to the tendering holders,
unless otherwise provided in the letter of transmittal, as soon as practicable
following         , 1999, unless the exchange offer is extended.
 
    In addition, the Company reserves the right in its sole discretion to
purchase or make offers for any Old Notes that remain outstanding after the
expiration date or, as set forth under "--Conditions to the exchange offer," to
terminate the exchange offer and, to the extent permitted by applicable law,
purchase Old Notes in the open market, in privately negotiated transactions, or
otherwise. The terms of any such purchases or offers could differ from the terms
of the exchange offer.
 
    By tendering, each holder will represent to the Company that, among other
things, (i) the New Notes acquired pursuant to the exchange offer are being
obtained in the ordinary course of business of the person receiving such New
Notes, whether or not such person is the registered holder, (ii) the holder is
not engaging in and does not intend to engage in a distribution of such New
Notes, (iii) the holder does not have an arrangement or understanding with any
person to participate in the distribution of such New Notes and (iv) the holder
is not an "affiliate," as defined under Rule 405 of the Securities Act, of the
Company.
 
                                       24
<PAGE>
    In all cases, issuance of New Notes for Old Notes that are accepted for
exchange pursuant to the exchange offer will be made only after timely receipt
by the Exchange Agent of certificates for such Old Notes or a timely Book-Entry
Confirmation of such Old Notes into the Exchange Agent's account at the
Book-Entry Transfer Facility, a properly completed and duly executed letter of
transmittal (or, with respect to the DTC and its participants, electronic
instructions in which the tendering holder acknowledges its receipt of and
agreement to be bound by the letter of transmittal), and all other required
documents. If any tendered Old Notes are not accepted for any reason set forth
in the terms and conditions of the exchange offer or if Old Notes are submitted
for a greater principal amount than the holder desires to exchange, such
unaccepted or non-exchanged Old Notes will be returned without expense to the
tendering holder thereof (or, in the case of Old Notes tendered by book-entry
transfer into the Exchange Agent's account at the Book-Entry Transfer Facility
pursuant to the book-entry transfer procedures described below, such
nonexchanged Old Notes will be credited to an account maintained with such
Book-Entry Transfer Facility) as promptly as practicable after the expiration or
termination of the exchange offer.
 
    Each broker-dealer that receives New Notes for its own account in exchange
for Old Notes, where such Old Notes were acquired by such broker-dealer as a
result of market-making activities or other trading activities, must acknowledge
that it will deliver a prospectus in connection with any resale of such New
Notes. See "Plan of Distribution."
 
BOOK-ENTRY TRANSFER
 
    The Exchange Agent will make a request to establish an account with respect
to the Old Notes at the Book-Entry Transfer Facility for purposes of the
exchange offer within two business days after the date of this Prospectus, and
any financial institution that is a participant in the Book-Entry Transfer
Facility's systems may make book-entry delivery of Old Notes being tendered by
causing the Book-Entry Transfer Facility to transfer such Old Notes into the
Exchange Agent's account at the Book-Entry Transfer Facility in accordance with
such Book-Entry Transfer Facility's procedures for transfer. However, although
delivery of Old Notes may be effected through book-entry transfer at the Book-
Entry Transfer Facility, the letter of transmittal or copy thereof, with any
required signature guarantees and any other required documents, must, in any
case other than as set forth in the following paragraph, be transmitted to and
received by the Exchange Agent at the address set forth under "--Exchange Agent"
on or prior to the expiration date or the guaranteed delivery procedures
described below must be complied with.
 
    DTC's Automated Tender Offer Program ("ATOP") is the only method of
processing exchange offers through DTC. To accept the exchange offer through
ATOP, participants in DTC must send electronic instructions to DTC through DTC's
communication system in lieu of sending a signed, hard copy letter of
transmittal. DTC is obligated to communicate those electronic instructions to
the Exchange Agent. To tender Old Notes through ATOP, the electronic
instructions sent to DTC and transmitted by DTC to the Exchange Agent must
contain the character by which the participant acknowledges its receipt of and
agrees to be bound by the letter of transmittal.
 
GUARANTEED DELIVERY PROCEDURES
 
    If a registered holder of the Old Notes desires to tender such Old Notes and
the Old Notes are not immediately available, or time will not permit such
holder's Old Notes or other required documents to reach the Exchange Agent
before the expiration date, or the procedure for book-entry transfer cannot be
completed on a timely basis, a tender may be effected if (i) the tender is made
through an Eligible Institution, (ii) prior to the expiration date, the Exchange
Agent receives from such Eligible Institution a properly completed and duly
executed letter of transmittal (or a facsimile thereof) and notice of guaranteed
delivery, substantially in the form provided by the Company (by telegram, telex,
fax transmission, mail or hand delivery), setting forth the name and address of
the holder of Old Notes
 
                                       25
<PAGE>
and the amount of Old Notes tendered, stating that the tender is being made
thereby and guaranteeing that within three New York Stock Exchange, Inc.
("NYSE") trading days after the date of execution of the notice of guaranteed
delivery, the certificates for all physically tendered Old Notes, in proper form
for transfer, or a Book-Entry Confirmation, as the case may be, will be
deposited by the Eligible Institution with the Exchange Agent and (iii) the
certificates for all physically tendered Old Notes, in proper form for transfer,
or a Book-Entry Confirmation, as the case may be, are received by the Exchange
Agent within three NYSE trading days after the date of execution of the notice
of guaranteed delivery.
 
WITHDRAWAL RIGHTS
 
    Tenders of Old Notes may be withdrawn at any time prior to 5:00 p.m., New
York City time, on the expiration date.
 
    For a withdrawal of a tender of Old Notes to be effective, a written or (for
DTC participants) electronic ATOP transmission notice of withdrawal must be
received by the Exchange Agent at its address set forth under "--Exchange Agent"
prior to 5:00 p.m., New York City time, on the expiration date. Any such notice
of withdrawal must (i) specify the name of the person having deposited the Old
Notes to be withdrawn (the "Depositor"), (ii) identify the Old Notes to be
withdrawn (including the certificate number or numbers and principal amount of
such Old Notes), (iii) be signed by the holder in the same manner as the
original signature on the letter of transmittal by which such Old Notes were
tendered (including any required signature guarantees) or be accompanied by
documents of transfer sufficient to have the Trustee register the transfer of
such Old Notes into the name of the person withdrawing the tender, and (iv)
specify the name in which any such Old Notes are to be registered, if different
from that of the Depositor. All questions as to the validity, form, and
eligibility (including time of receipt) of such notices will be determined by
the Company, whose determination shall be final and binding on all parties. Any
Old Notes so withdrawn will be deemed not to have been validly tendered for
exchange for purposes of the exchange offer. Any Old Notes which have been
tendered for exchange but which are not exchanged for any reason will be
returned to the holder thereof without cost to such holder as soon as
practicable after withdrawal, rejection of tender, or termination of the
exchange offer. Properly withdrawn Old Notes may be retendered by following one
of the procedures under "--Procedures for Tendering" at any time on or prior to
the expiration date.
 
CONDITIONS TO THE EXCHANGE OFFER
 
    Notwithstanding any other provision of the exchange offer, the Company shall
not be required to accept for exchange, or to issue New Notes in exchange for,
any Old Notes and may terminate or amend the exchange offer if at any time
before the acceptance of such Old Notes for exchange or the exchange of the New
Notes for such Old Notes, the Company determines that the exchange offer
violates applicable law, any applicable interpretation of the staff of the
Commission or any order of any governmental agency or court of competent
jurisdiction.
 
    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. The failure by the Company at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right and each such right shall be deemed an ongoing right which may be asserted
at any time and from time to time.
 
    In addition, the Company will not accept for exchange any Old Notes
tendered, and no New Notes will be issued in exchange for any such Old Notes, if
at such time any stop order shall be threatened or in effect with respect to the
Registration Statement of which this Prospectus constitutes a part or the
qualification of the Indenture under the Trust Indenture Act of 1939, as
amended. In any such event
 
                                       26
<PAGE>
the Company is required to use every reasonable effort to obtain the withdrawal
of any stop order at the earliest possible time.

expenses to be incurred in connection with the exchange offer will be paid by
the Company and are estimated in the aggregate to be $      , which includes
fees and expenses of the Exchange Agent, accounting, legal, printing, and
related fees and expenses.
 
TRANSFER TAXES
 
    Holders who tender their Old Notes for exchange will not be obligated to pay
any transfer taxes in connection therewith, except that holders who instruct the

tendered or not accepted in the exchange offer be returned to, a person other
than the registered tendering holder will be responsible for the payment of any
applicable transfer tax thereon.

                                USE OF PROCEEDS
 
    We will not receive any cash proceeds from the issuance of the New Notes. In
consideration for issuing the New Notes as contemplated in this Prospectus, we
will receive in exchange Old Notes in like principal amount, which will be
canceled and as such will not result in any increase in our indebtedness.

Recapitalization, (ii) to repay indebtedness, and (iii) to pay related fees and
expenses. The following table sets forth the sources and uses of funds for the

(1) The New Credit Facility consists of: (i) the Revolving Credit Facility which
    provides for borrowings of up to $30.0 million, of which approximately $2.6
    million was drawn in connection with the Recapitalization with the remainder
    undrawn at closing and available for certain permitted acquisitions and for
    general corporate purposes, including working capital requirements; (ii) the
    Tranche A Facility, which provides for term debt of $45.0 million; and (iii)
    the Tranche B Facility which provides for term debt of $45.0 million. See
    "Description of Other Indebtedness--The Company--The New Credit Facility."
    For purposes of the September 30, 1998 pro forma presentation above, $3.1
    million was assumed to have been drawn on the Revolving Credit Facility in
    connection with the Recapitalization because the Company had less cash and
    cash equivalents on that date.

             UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL INFORMATION
 
    The following pro forma consolidated financial information of the Company
and Holdings has been derived by the application of pro forma adjustments to
Holdings' historical consolidated financial statements for the year ended
September 30, 1998 The pro forma consolidated statements of operations give
effect to the Recapitalization and related transactions as if such transactions
had been consummated on October 1, 1997. The pro forma consolidated balance
sheet gives effect to the Recapitalization and related transactions as if such
transactions had occurred as of September 30, 1998. The adjustments necessary to
fairly present this pro forma consolidated financial information have been made
based on available information and in the opinion of management are reasonable
and are described in the accompanying notes. The pro forma consolidated
financial information should not be considered indicative of actual results that
would have been achieved had the Recapitalization and related transactions been
consummated on the respective dates indicated and do not purport to indicate
balance sheet data or results of operations as of any future date or for any
future period. You should read the pro forma consolidated financial statements
together with the "Use of Proceeds," the "The Transactions" and the
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" sections and the Consolidated Historical Financial Statements and
the notes thereto, and other financial information included elsewhere in this
Prospectus.
 
    The pro forma adjustments were applied to the respective historical
consolidated financial statements to reflect and account for the Transactions as
a recapitalization. As a result, such adjustments will have no impact on the
historical basis of either the Company's or Holdings' assets and liabilities.
Accordingly, the Transactions have not impacted the historical basis of the
Company's and Holding's assets and liabilities.
 
    The unaudited consolidated pro forma statement of operations does not
include pro forma adjustments for certain non-recurring costs and charges,
consisting primarily of compensation costs for one-time management bonuses and
stock options which were cancelled, in each case, in conjunction with the
Recapitalization, the cost of terminating a financial advisory services
agreement with an affiliate of the Company's largest stockholder, the write-off
of deferred financing costs, and professional, advisory and financing fees. A
one-time charge of approximately $39.6 million ($28.8 million after tax) was
recorded in the first quarter of fiscal 1999. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Overview."

    (2) The amounts in this column represent the adjustments necessary to
determine the Company's pro forma consolidated balance sheet after giving effect
to the Transactions.
 
        (a) This adjustment reflects the use of cash of $19.5 million on the
    balance sheet as of September 30, 1998 to fund a portion of the
    Recapitalization. In management's opinion, the existing cash will not need
    to be used to meet ordinary working capital needs. The actual cash on hand
    upon consummation of the Recapitalization was more than this assumed amount.
    (See "Use of Proceeds").
 
        (b) This adjustment represents the recognition of the estimated tax
    benefits attributable to the write-off of unamortized debt issuance costs
    relating to the Company's existing indebtedness (see (c) below).
 
        (c) This adjustment represents the recognition of $10.7 million of debt
    issuance costs associated with the New Credit Facility and the Notes less
    the write-off of $0.6 million of unamortized debt issuance costs relating to
    the Company's existing indebtedness.
 
        (d) This adjustment represents the recognition of the New Credit
    Facility of $93.1 million and the Notes of $125.0 million along with the
    repayment of $45.1 million of existing indebtedness (current and long-term
    portion) and accrued interest. The amount of the new indebtedness that is
    expected to be payable within one year is $6.1 million. The actual amount
    borrowed under the New Credit Facility was less than $93.1 million because
    the Company's cash balances utilized in the Transactions were more than the
    $19.5 million assumed under (1) above. (See "Use of Proceeds.")
 
                                       35
<PAGE>
        (e) This adjustment includes the following:
 
- - The recognition of a $181.8 million cash dividend to Holdings which is
  comprised of the proceeds from the New Credit Facility and the Notes (see Note
  (d) above) and the Company's cash balance as of September 30, 1998 (see Note
  (a) above), less the repayment of existing indebtedness and fees and expenses
  related to the Transactions.
 
- - The elimination of the outstanding warrants of $16.7 million.
 
- - A $0.4 million after-tax charge resulting from the write-off of unamortized
  deferred loan costs relating to the Company's existing indebtedness which was
  repaid.
 
    (3) The amounts in this column represent the adjustments related to the
Holdings PIK Notes and other adjustments necessary to determine Holdings' pro
forma consolidated balance sheet after giving effect to the Transactions.
 
        (a) This adjustment represents the recognition of the estimated income
    tax benefits resulting from the settlement of Holdings' stock options in
    connection with the Transactions and the estimated fees and expenses related
    to the Recapitalization.
 
        (b) This adjustment represents the reclassification of the Company's
    accrued income tax liability against Holdings' income tax receivable
    associated with the settlement of stock options and the fees and expenses
    (see (a) above).
 
        (c) This adjustment represents the recognition of deferred loan costs
    associated with the Holdings PIK Notes.
 
        (d) This adjustment represents the recognition of the Holdings PIK Notes
    (including unamortized discount of $2.6 million).
 
        (e) This adjustment represents the issuance of $100.2 million of
    additional capital stock to Odyssey and $2.6 million of capital stock in
    connection with the Holdings PIK Notes.
 
        (f) This adjustment represents the payment of consideration for the
    Recapitalization along with the settlement of the stock options determined
    as follows:

        (g) This adjustment represents the recognition of a $2.0 million expense
    for certain fees and expenses related to the Recapitalization.
 
        (h) This adjustment recognizes the elimination of capital stock and
    paid-in capital associated with the shares of common stock that were
    repurchased in connection with the Recapitalization.
 
    (4) In connection with the formation of the Company on September 30, 1993,
the Company issued subordinated notes which included detachable warrants to
purchase approximately 16,000 shares of non-voting common stock of Holdings at a
price of $0.10 per share, exercisable upon certain change of control events. If
no such event had occurred before July 31, 1999, warrant holders had the right
to require the Company to repurchase the warrants at their then-appraised fair
market value, which is known as the "put value." The carrying value of the put
warrants represents the estimated put value of the warrants on September 30,
1998 based upon the provisions of the Transactions. The put warrants were
retired in connection with the Recapitalization.

         SELECTED HISTORICAL AND PRO FORMA CONSOLIDATED FINANCIAL DATA
 
    The following table sets forth selected historical consolidated financial
information of Holdings and the Company. The selected historical consolidated
financial data for the fiscal years ended September 30, 1998, 1997, and 1996
have been derived from Holdings' consolidated financial statements, which have
been audited by Deloitte & Touche LLP, independent auditors. The selected
historical consolidated audited financial data for the fiscal years ended
September 30, 1995 and 1994, which have also been derived from Holdings'
consolidated financial statements, have been adjusted to give retroactive effect
to the change in accounting for put warrants as described in Note 17 to the
Consolidated Historical Financial Statements of Holdings included elsewhere in
this Prospectus. Because Holdings has no operations of its own and, prior to the
Recapitalization, had no assets or liabilities other than its equity interest in
the Company, the historical consolidated financial information of Holdings for
each of the years in the five-year period ended September 30, 1998 are identical
to the historical consolidated financial information of the Company. The pro
forma financial information set forth below gives effect to the Transactions as
if they had occurred at the beginning of the period or as of the balance sheet
date, as applicable. The pro forma financial information is not necessarily
indicative of either future results of operations or the results that might have
occurred if the foregoing transactions had been consummated on such date. There
can be no assurance that assumptions used in the preparation of the pro forma
financial data will prove to be correct. The Marathon Acquisition was completed
on August 8, 1997.
 
    You should read the following table together with the "Unaudited Pro Forma
Consolidated Financial Information" and "Management's Discussion and Analysis of
Financial Condition and Results of Operations" sections and the Consolidated
Historical Financial Statements and the notes thereto included elsewhere in this
Prospectus.

(1) The Company acquired Marathon on August 8, 1997. The acquisition was
    accounted for as a purchase. The results of operations of Marathon are
    included in Holdings' consolidated financial statements from the date of
    such acquisition. See Marathon's historical financial statements and the
    notes thereto included elsewhere in this Prospectus.
 
(2) Operating income (loss) includes the effect of a non-cash charge of $4,473
    in fiscal 1994 due to a purchase accounting adjustment to inventory
    associated with the acquisition of the Aerospace Components Group of IMO and
    a non-cash charge of $666 in fiscal 1997 and $242 in fiscal 1998 due to a
    purchase accounting adjustment to inventory associated with the acquisition
    of Marathon. The $100 adjustment to the Company's 1998 pro forma operating
    income represents the elimination of the advisory fee payable to an
    affiliate of one of the Company's stockholders.
 
(3) In connection with the formation of the Company on September 30, 1993, the
    Company issued subordinated notes which included detachable warrants to
    purchase approximately 16,000 shares of non-voting common stock of Holdings
    at a price of $0.10 per share, exercisable upon certain change of control
    events, including the Recapitalization. The warrant put value adjustment for
    each period indicated reflects the increase in the estimated put value of
    these warrants that occurred during that period.
 
(4) The extraordinary charge in fiscal 1997 relates to costs associated with the
    retirement of the subordinated notes referred to in footnote (3) above
    issued at the time of the Company's formation in 1993.
 
(5) EBITDA, As Defined, represents earnings before interest, taxes, depreciation
    and amortization and the warrant put value adjustments and prior to the
    impact of the purchase accounting adjustments to inventory referred to in

   Although EBITDA, As Defined, is not a measure of performance calculated in
    accordance with GAAP, the Company believes that EBITDA, As Defined, is
    accepted as a generally recognized measure of performance in the Company's
    industry. Nevertheless, this measure should not be considered in isolation
    or as a substitute for operating income, net income, net cash provided by
    operating activities or any other measure for determining the Company's
    operating performance or liquidity which is calculated in accordance with
    GAAP.
 
(6) For purposes of computing the ratio of earnings to fixed charges, earnings
    consist of earnings before income taxes plus fixed charges. Fixed charges
    consist of interest expense, amortization of debt expense and the portion
    (approximately 33%) of rental expense that management believes is
    representative of the interest component of rental expense. Earnings were
    insufficient to cover fixed charges by $7,630 and $127 for fiscal 1994 and
    1995, respectively.

OVERVIEW
 
    TransDigm is a leading supplier of highly engineered aircraft components for
use on nearly all commercial and military aircraft. The Company sells its
products to commercial airlines and aircraft maintenance facilities in the
aftermarket, to most original equipment manufacturers ("OEMs") of aircraft and
to various agencies of the United States government. Sales of the Company's
products are made directly to these organizations as well as through U.S. and
international distributors who maintain inventories throughout the world of
products purchased from the Company and others. The Company generates most of
its EBITDA, As Defined from sales of replacement parts in the aftermarket (i.e.
to airlines). This is because most of the Company's OEM sales are on an
exclusive sole source basis; therefore, in most cases, the Company is the only
certified provider of these parts in the aftermarket. Because aftermarket parts
sales are driven by the size of the worldwide aircraft fleet, they are
relatively stable and generate recurring revenues over the life of an aircraft
that are many times the size of the original OEM purchases.
 
    The Company provides its products to commercial airlines (such as United
Airlines and Continental Airlines), large commercial transport and regional and
business aircraft OEMs (such as Boeing, Bombardier and Cessna) and various
agencies of the United States government. While aftermarket and OEM sales have
historically each accounted for approximately half of the Company's net sales,
aftermarket sales typically carry a substantially higher gross margin than sales
to OEMs.
 
    Management believes that the aircraft components industry has historically
been sensitive to changes in revenue passenger miles and, to a lesser extent, to
airline profitability, each of which has historically been correlated with
changes in general economic conditions, and the size and age of the worldwide
aircraft fleet. On a worldwide basis, revenue passenger miles have increased
from approximately 978 billion in 1985 to approximately 1,719 billion in 1996 at
a compound annual growth rate of approximately 6%. See "Business--Industry." In
addition, management believes less than 20% of the Company's annual net sales
during fiscal 1998 were attributable to sales to manufacturers of large
commercial transports such as Boeing and Airbus. As a result, increases and
decreases in the manufacture of large commercial transports only affect a
portion of the Company's net sales.
 
    Management has, since 1993, implemented a number of programs that have had a
positive impact on the profitability and strategic positioning of the Company.
To ensure a competitive cost structure, the Company consolidated the Adel
Fasteners and Wiggins Connectors divisions into AdelWiggins and the AeroProducts
and Controlex divisions into AeroControlex and, in fiscal 1994, consolidated the
Company's four manufacturing facilities into two locations. Beginning in fiscal
1994, management reorganized the business along 11 major product lines in order
to streamline new business initiatives, increase accountability and facilitate
greater responsiveness to customer needs.
 
    The Company's historical financial results are also affected by the
acquisition of Marathon on August 8, 1997. Marathon's operations were
consolidated with those of the Company as of the acquisition date.
 
                                       39
<PAGE>
    The Transactions were recorded as a recapitalization for accounting
purposes. As a result of the Transactions, including the financing and the
application of the proceeds thereof, the Company incurred certain nonrecurring
costs and charges, consisting primarily of compensation costs for management
bonuses and stock options which were canceled in conjunction with the
Recapitalization, the cost of terminating a financial advisory services
agreement with an affiliate of one of the Company's stockholders, the write-off
of deferred financing costs, and professional, advisory and financing fees. A
one-time charge of approximately $39.6 million ($28.8 million after tax) was
recorded in the first quarter of fiscal 1999. Because the cash costs included in
this charge were funded principally through the proceeds of the offering of the
Old Notes and borrowings under the New Credit Facility, this cost did not
materially impact the Company's liquidity, ongoing operations or market
position. For a discussion of the consequences of the incurrence of indebtedness
in connection with the Transactions, see the heading "--Liquidity and Capital
Resources" in this section.

(1) In connection with the formation of the Company on September 30, 1993, the
    Company issued subordinated notes which included detachable warrants to
    purchase approximately 16,000 shares of non-voting common stock of Holdings
    at a price of $0.10 per share, exercisable upon certain change of control
    events, including the Recapitalization. The warrant put value adjustment for
    each period indicated reflects the increase in the estimated put value of
    these warrants that occurred during that period.
 
CHANGES IN RESULTS OF OPERATIONS
 
FISCAL YEAR ENDED SEPTEMBER 30, 1998 COMPARED WITH FISCAL YEAR ENDED SEPTEMBER
  30, 1997
 
- - NET SALES. Net sales increased by $32.7 million, or 42%, to $110.8 million for
  fiscal 1998 from $78.1 million for fiscal 1997. Approximately $19.5 million of
  this increase was attributable to the acquisition of Marathon on August 8,
  1997. The remainder of the increase was attributable to an increase in sales
  volume resulting from new business initiatives, higher selling prices
  primarily related to aftermarket sales and an industry-wide increase in
  demand.
 
- - GROSS PROFIT. Gross profit (net sales less cost of sales) increased by $22.6
  million, or 78.8%, to $51.5 million for fiscal 1998 from $28.8 million for
  fiscal 1997. Approximately $8.7 million of this
 
                                       40
<PAGE>
  increase was attributable to the acquisition of Marathon. The remainder of the
  increase was attributable to the higher selling prices and sales volumes and
  internal productivity initiatives. Gross profit increased as a percentage of
  net sales from 36.9% in the 1997 period to 46.4% in fiscal 1998. This increase
  was primarily attributable to higher selling prices and manufacturing
  efficiencies resulting from the internal productivity initiatives and the
  increase in sales volumes.
 
- - SELLING AND ADMINISTRATIVE. Selling and administrative expense increased by
  $2.9 million, or 38.2%, to $10.5 million for fiscal 1998 from $7.6 million for
  fiscal 1997. This increase was primarily attributable to the Marathon
  acquisition. Selling and administrative expenses as a percentage of net sales
  remained relatively constant at 9.7% in fiscal 1997 and 9.4% in fiscal 1998.
 
- - AMORTIZATION OF INTANGIBLES. Amortization of intangibles increased by $0.3
  million, or 14.3%, to $2.4 million for fiscal 1998 from $2.1 million for
  fiscal 1997. Higher goodwill amortization relating to the acquisition of
  Marathon was partially offset by a reduction in amortization of other
  intangible assets which became fully amortized in fiscal 1997.
 
- - RESEARCH AND DEVELOPMENT. Research and development expense increased by $0.6
  million, or 54.5%, to $1.7 million for fiscal 1998 from $1.1 million for
  fiscal 1997. This increase was primarily attributable to the acquisition of
  Marathon. Research and development expense as a percentage of net sales
  remained relatively constant at 1.4% in fiscal 1997 and 1.6% in fiscal 1998.
 
- - OPERATING INCOME. Operating income increased by $18.7 million, or 103.3%, to
  $36.8 million for fiscal 1998 from $18.1 million for fiscal 1997.
  Approximately $4.6 million of this increase was attributable to the
  acquisition of Marathon and the remainder to the other increases in gross
  profit discussed above. As a percentage of revenues, operating income
  increased to 33.2% in fiscal 1998 from 23.1% in fiscal 1997.
 
- - INTEREST EXPENSE. Interest expense for fiscal 1998 approximated the amount for
  fiscal 1997 at $3.2 million and $3.5 million, respectively. An increase in
  borrowings related to the acquisition of Marathon was partially offset by
  lower borrowing costs resulting from refinancing of the Company's subordinated
  notes.
 
- - INCOME TAXES. Income tax expense as a percentage of income before income taxes
  and the non-deductible warrant put value adjustment increased to 38.6% in
  fiscal 1998 from 35.5% in fiscal 1997. The increase in the effective rate
  resulted from higher non-deductible expenses, including the amortization of
  goodwill recognized in connection with the Marathon acquisition.
 
- - NET INCOME. Net income increased by $10.9 million, or 340.6%, to $14.1 million
  for fiscal 1998 from $3.2 million for fiscal 1997 primarily as result of the
  factors referred to above and an extraordinary loss in 1997 partially offset
  by the warrant put value adjustment.
 
FISCAL YEAR ENDED SEPTEMBER 30, 1997 COMPARED WITH FISCAL YEAR ENDED SEPTEMBER
  30, 1996
 
- - NET SALES. Net sales increased by $15.3 million, or 24.3%, to $78.2 million
  for fiscal 1997 from $62.9 million for fiscal 1996. This increase was
  primarily attributable to an industry-wide increase in demand and increases in
  sales volume resulting from new business initiatives as well as higher selling
  prices primarily related to aftermarket sales. The remainder of the increase,
  or approximately $3.0 million, was attributable to the acquisition of
  Marathon.
 
- - GROSS PROFIT. Gross profit increased by $7.9 million, or 37.6%, to $28.9
  million for fiscal 1997 from $21.0 million for fiscal 1996. This increase was
  attributable to the higher selling prices and sales volumes and internal
  productivity initiatives, all of which was partially offset by higher cost of
  sales at Marathon resulting from the write-up of Marathon's inventory in place
  at the time of the Marathon acquisition. Gross profit also increased as a
  percentage of net sales from 33.4% in fiscal 1996 to 36.9% in fiscal 1997.
  This increase was primarily attributable to higher selling prices and
 
                                       41
<PAGE>
  manufacturing efficiencies resulting from the internal productivity
  initiatives and the increase in sales volumes, as partially offset by the
  acquisition of Marathon.
 
- - SELLING AND ADMINISTRATIVE. Selling and administrative expense increased by
  $1.1 million, or 16.9%, to $7.6 million for fiscal 1997 from $6.5 million for
  fiscal 1996. This increase was primarily attributable to the acquisition of
  Marathon, the increase in sales volume (which increased commission expense)
  and the relocation of the Company's corporate headquarters. Selling and
  administrative expenses declined as a percentage of net sales from 10.3% in
  fiscal 1996 to 9.7% in fiscal 1997 due to the increase in net sales referred
  to above coupled with an effort to control expenses.
 
- - AMORTIZATION OF INTANGIBLES. Amortization of intangibles decreased by $1.7
  million, or 44.7%, to $2.1 million for fiscal 1997 from $3.8 million for
  fiscal 1996. Amortization of intangibles decreased by $2.0 million as a result
  of the termination of an agreement not to compete at the end of fiscal 1996,
  partially offset by higher amortization of goodwill relating to the
  acquisition of Marathon.
 
- - RESEARCH AND DEVELOPMENT. Research and development expense increased by $0.3
  million, or 37.5%, to $1.1 million for fiscal 1997 from $0.8 million for
  fiscal 1996. This increase was primarily attributable to continued new product
  development. Research and development expense as a percentage of net sales
  remained relatively constant at 1.3% in fiscal 1996 and 1.4% in fiscal 1997.
 
- - OPERATING INCOME. Operating income increased by $8.2 million, or 82.8%, to
  $18.1 million for fiscal 1997 from $9.9 million for fiscal 1996. As a
  percentage of revenues, operating income increased to 23.1% in fiscal 1997
  from 15.7% in fiscal 1996. This increase was primarily attributable to the
  increase in sales volume and gross profits referred to above.
 
- - INTEREST EXPENSE. Interest expense decreased by $1.0 million, or 22.2%, to
  $3.5 million for fiscal 1997 from $4.5 million for fiscal 1996 as a result of
  a decrease in the average level of outstanding borrowings during fiscal 1997.
 
- - INCOME TAXES. Income tax expense as a percentage of income before income taxes
  and the non-deductible warrant put value adjustment decreased to 35.5% in
  fiscal 1997 from 38.0% in fiscal 1996. The decrease in the effective rate
  resulted from foreign sales corporation earnings in fiscal 1997, partially
  offset by higher non-deductible expenses, including the amortization of
  goodwill recognized in connection with the Marathon acquisition.
 
- - NET INCOME. Net income increased by $2.0 million, or 166.7%, to $3.2 million
  for fiscal 1997 from $1.2 million for fiscal 1996 primarily as result of the
  factors noted above partially offset by the warrant put value adjustment and a
  $1.5 million extraordinary loss in fiscal 1997.
 
- - EXTRAORDINARY LOSS. The extraordinary loss in fiscal 1997 of $1.5 million
  represents prepayment costs and the write-off of unamortized debt issuance
  costs, net of income tax benefits, related to the redemption of the
  subordinated notes which were refinanced with a new $70.0 million credit
  facility in September 1997.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    The Company generated $23.5 million of cash from operating activities in
fiscal 1998 compared to $17.5 million in fiscal 1997 and $18.7 million in 1996.
Such increase in operating cash flows is due to improved operating results
partially offset by higher working capital.
 
    Cash used in investing activities was approximately $4.3 million in fiscal
1998 compared with $43.2 million in fiscal 1997 and $2.5 million in fiscal 1996.
Cash used in investing activities in fiscal 1997 includes $40.9 million related
to the acquisition of Marathon (net of cash acquired of $0.7 million). The
Company's expenditures for property, plant and equipment were $2.5 million in
fiscal 1996, $2.3 million in fiscal 1997 and $5.1 million in fiscal 1998.
 
                                       42
<PAGE>
    Cash used in financing activities for fiscal 1998 was $5.1 million compared
to cash provided by financing activities of $28.2 million for fiscal 1997 and
cash used in financing activities of $13.5 million for fiscal 1996. During
fiscal 1997, the Company obtained a $70.0 million credit facility, the
outstanding balance under which has been repaid in connection with the
Transactions. Borrowings under this facility of $50.0 million in fiscal 1997
were used to help finance the Marathon acquisition and redeem the Company's
outstanding subordinated notes.
 
    In connection with the Recapitalization, the Company incurred substantial
indebtedness and refinanced certain other indebtedness including all borrowings
under the prior credit facility. See the "Capitalization" section. As of
September 30, 1998, on a pro forma basis, Holdings had indebtedness consisting
of $20.0 million in face value of the Holdings PIK Notes and the Company had
indebtedness consisting of (i) $125.0 million in principal amount of the Old
Notes and (ii) $93.1 million of borrowings under the New Credit Facility, which
consisted of an assumed initial draw of $3.1 million under a $30.0 million
Revolving Credit Facility, a $45.0 million term loan under the Tranche A
Facility and a $45.0 million term loan under the Tranche B Facility. The actual
amount borrowed under the Revolving Credit Facility as of the consummation of
the Transactions on December 3, 1998 was $2.6 million because the Company's cash
balances utilized in the Transactions were more than the amount assumed for the
purposes of presenting the pro forma financial information. See "Unaudited Pro
Forma Consolidated Financial Information" and the notes thereto. The interest
rate for the New Credit Facility is, at the Company's option, either (i) a
floating rate equal to the Base Rate (as defined) plus the Applicable Margin, or
(ii) the Eurodollar Rate (as defined) for fixed periods of one, two, three, or
six months, plus the Applicable Margin. The New Credit Facility is subject to
mandatory prepayment with a defined percentage of net proceeds from certain
asset sales, insurance proceeds or other awards (payable in connection with the
loss, destruction or condemnation of any assets), certain new debt and equity
offerings and 50% of excess cash flow (as defined in the New Credit Facility) in
excess of a predetermined amount under the New Credit Facility.
 
    The Old Notes bear, and the New Notes will bear, interest at 10 3/8%. The
New Notes and the Old Notes will not require principal payments prior to
maturity. The Revolving Credit Facility and the Tranche A Facility will each
mature on the six year anniversary of the initial borrowing date and the Tranche
B Facility will mature on the seven and a half year anniversary of the initial
borrowing date. The New Credit Facility requires the Company to amortize the
outstanding indebtedness under each of the Tranche A Facility and the Tranche B
Facility, commencing in year 1999, and contains restrictive covenants that will,
among other things, limit the incurrence of additional indebtedness, the payment
of dividends, transactions with affiliates, asset sales, acquisitions, mergers
and consolidations, liens and encumbrances, and prepayments of other
indebtedness. See the "Description of the New Notes" and "Description of Other
Indebtedness--The Company--The New Credit Facility" section.
 
    The Company's primary cash needs will consist of capital expenditures and
debt service. The Company incurs capital expenditures for the purpose of
maintaining and replacing existing equipment and facilities and, from time to
time, for facility expansion. Capital expenditures totaled approximately $2.5
million, $2.3 million and $5.1 million in fiscal 1996, fiscal 1997 and fiscal
1998, respectively. The Company estimates that capital expenditures will total
approximately $5.6 million in fiscal 1999.
 
    The Company intends to pursue additional acquisitions that present
opportunities to realize significant synergies, operating expense economies or
overhead cost savings or to increase the Company's market position. The Company
regularly engages in discussions with respect to potential acquisitions and
investments. However, there are no binding agreements with respect to any
material acquisitions at this time, and we cannot assure you that we will be
able to reach an agreement with respect to any future acquisition. The Company's
acquisition strategy may require substantial capital, and no assurance can be
given that the Company will be able to raise any necessary funds on terms
acceptable to the Company or at all. If the Company incurs additional debt to
finance acquisitions, its total interest expense will increase. See "Risk
Factors--Risks Related to Potential Future Acquisitions."
 
                                       43
<PAGE>
    The Company's ability to make scheduled payments of principal of, or to pay
the interest on, or to refinance, its indebtedness (including the New Notes and
the Old Notes), or to fund planned capital expenditures and research and
development will depend on their future performance, which, to a certain extent,
is subject to general economic, financial, competitive, legislative, regulatory
and other factors that are beyond their control. Based upon the current level of
operations and anticipated cost savings and revenue growth, management believes
that cash flow from operations and available cash, together with available
borrowings under the New Credit Facility, will be adequate to meet the Company's
future liquidity needs for at least the next few years. The Company may,
however, need to refinance all or a portion of the principal of the New Notes
and the Old Notes on or prior to maturity. There can be no assurance that the
Company's business will generate sufficient cash flow from operations, that
anticipated revenue growth and operating improvements will be realized or that
future borrowings will be available under the New Credit Facility in an amount
sufficient to enable the Company to service its indebtedness, including the New
Notes and the Old Notes, or to fund its other liquidity needs. In addition,
there can be no assurance that the Company will be able to effect any such
refinancing on commercially reasonable terms or at all. See the "Risk Factors"
section.
 
BACKLOG
 
    Management believes that sales order backlog (i.e. orders for products that
have not yet been shipped) is a useful indicator of sales to OEMs. As of
September 30, 1998, the Company estimated its sales order backlog at $43.2
million compared to an estimated $40.9 million as of September 30, 1997. The
majority of the purchase orders outstanding as of September 30, 1998 are
scheduled for delivery within the next twelve months. Purchase orders are
generally subject to cancellation by the customer prior to shipment. The level
of unfilled purchase orders at any given date during the year will be materially
affected by the timing of the Company's receipt of purchase orders and the speed
with which those orders are filled. Accordingly the Company's backlog as of
September 30, 1998 is not necessarily indicative of actual shipments or sales
for any future period, and period-to-period comparisons may not be meaningful.
 
FOREIGN OPERATIONS
 
    The Company manufactures virtually all of its products in the United States.
However, a significant portion of the Company's current sales are conducted
abroad. These sales are subject to numerous additional risks, including the
impact of foreign government regulations, currency fluctuations, political
uncertainties and differences in business practices. There can be no assurance
that foreign governments will not adopt regulations or take other action that
would have a direct or indirect adverse impact on the business or market
opportunities of the Company within such governments' countries. Furthermore,
there can be no assurance that the political, cultural and economic climate
outside the United States will be favorable to the Company's operations and
growth strategy.
 
INFLATION
 
    Many of the Company's raw materials and operating expenses are sensitive to
the effects of inflation, which could result in higher operating costs. The
effects of inflation on the Company's businesses during fiscal 1998, 1997 and
1996 were not significant.
 
NEW ACCOUNTING STANDARDS
 
    In June 1997, the Financial Accounting Standards Board issued SFAS No. 130,
"Reporting Comprehensive Income." The statement requires that an enterprise
classify items of other comprehensive income by their nature in a financial
statement and display the accumulated balance of other comprehensive income
separately from retained earnings and additional paid-in capital in the
 
                                       44
<PAGE>
equity section of a statement of financial position. The Company will adopt this
standard during fiscal 1999.
 
    In June 1997, the Financial Accounting Standards Board issued SFAS No. 131,
"Disclosures About Segments of an Enterprise and Related Information." The
statement requires that a public business enterprise report financial and
descriptive information about its reportable operating segments such as a
measure of segment profit or loss, certain specific revenue and expense items,
and segment assets. The Company will adopt this standard during fiscal 1999.
 
    In February 1998, the Financial Accounting Standards Board issued SFAS No.
132, "Employer's Disclosures about Pensions and Other Postretirement Benefits."
The statement requires an enterprise to disclose certain information about its
pension and postretirement benefits, including a reconciliation of beginning and
ending balances of the benefit obligation, the funded status of the plans, and
the amount of net periodic benefit cost recognized. The Company will adopt this
standard in fiscal 1999.
 
    In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities." This statement
establishes accounting and reporting standards for derivative instruments
embedded in other contracts, (collectively referred to as derivatives) and for
hedging activities. It requires that an entity recognize all derivatives as
either assets or liabilities in the statement of financial position and measure
those instruments at fair value. If certain conditions are met, a derivative may
be specifically designated as (a) a hedge of the exposure to changes in the fair
value of a recognized asset or liability or an unrecognized firm commitment, (b)
a hedge of the exposure to variable cash flows of a forecasted transaction, or
(c) a hedge of the foreign currency exposure of a net investment in a foreign
operation, an unrecognized firm commitment, an available-for-sale security, or a
foreign-currency-denominated forecasted transaction. The Company will adopt this
standard during fiscal 2000.
 
    While management has not completed its analysis of these new accounting
standards, the adoption of these standards is not expected to have a material
effect on the Company's financial statements.
 
IMPACT OF YEAR 2000 ISSUE
 
    We have completed a review of our computer systems and are completing a
review of our embedded systems in order to assess our exposure to Year 2000
issues. We purchased all of our computer software from third party vendors and
are relying on those vendors to make their software Year 2000 compliant. Except
for the vendor of our e-mail system, such vendors have provided us with third
party certifications that their systems are Year 2000 compliant.
 
    We do not, however, currently have any information concerning the Year 2000
compliance status of our suppliers and customers, including various agencies of
the United States government.
 
    In the event that Year 2000 problems arise within our Company or that our
significant suppliers or customers, including various agencies of the United
States government, do not successfully and timely achieve Year 2000 compliance,
the result may be a delay in our receiving orders and collecting payments,
leading to a temporary loss of revenue. We have incurred $180,000 in costs
associated with Year 2000 compliance and anticipate incurring $150,000 of
additional costs in the future. We may, however, have to bear further Year 2000
costs and expenses which could have a material adverse effect on our business.
 
    The Company has no formal contingency plan in the event Year 2000 problems
arise; however, the Company's accounting and business information systems are
not complex and manual procedures could be performed for a period of time to
provide the information necessary to continue to operate the business.

THE COMPANY
 
    TransDigm is a leading supplier of highly engineered aircraft components for
use on nearly all commercial and military aircraft. The Company sells its
products to commercial airlines, aircraft maintenance facilities, aircraft OEMs
and to various agencies of the United States government. The Company generates
most of its EBITDA, As Defined from sales of replacement parts in the
aftermarket (i.e. airlines). This is because most of the Company's OEM sales are
on an exclusive sole source basis; therefore, in most cases, the Company is the
only certified provider of these parts in the aftermarket. Because aftermarket
parts sales are driven by the size of the worldwide aircraft fleet, they are
relatively stable and generate recurring revenues over the life of an aircraft
that are many times the size of the original OEM purchases. In addition, because
the Company has over 40 years of experience in most of its product lines, it
benefits from a large and growing installed base of aircraft. For fiscal 1998,
the Company generated net sales, operating income and EBITDA, As Defined, of
$110.9 million, $36.8 million and $43.5 million, respectively.
 
    TransDigm differentiates itself based on its engineering and manufacturing
capabilities, and typically will not bid on non-proprietary "build to print"
business. The Company has developed strong product brand names within the
airline industry and a reputation for high quality, reliability and customer
service. The Company focuses on developing highly customized products to solve
specific problems of aircraft operators and manufacturers. Management estimates
that over 80% of the Company's products are of proprietary design. The Company
provides its products to commercial airlines (such as United Airlines and
Continental Airlines), large commercial transport and regional and business
aircraft OEMs (such as Boeing, Bombardier and Cessna) and various agencies of
the United States government. While aftermarket and OEM sales each typically
account for approximately half of the Company's revenues, aftermarket sales
typically carry a substantially higher gross margin than sales to OEMs.
 
    The Company is comprised of three business units: (i) AdelWiggins, (ii)
AeroControlex, and (iii) Marathon, each of which has a long history in the
aircraft components industry. AdelWiggins manufactures an extensive line of fuel
and hydraulic system connectors and specialized clamps, heaters and refueling
systems. AeroControlex manufactures customized fuel pumps, compressors, valves,
couplings and mechanical and electromechanical controls. Marathon manufactures
nickel cadmium batteries and static inverters. Marathon was acquired in August
1997 as a strategic complement to the AdelWiggins and AeroControlex businesses.
 
    TransDigm was formed in 1993 through a management-led buyout of IMO. Since
its formation, the Company has successfully established leadership positions in
well-defined, profitable niches of the aircraft components market that it
believes offer sustainable growth opportunities.
 
INDUSTRY OVERVIEW
 
    The aircraft components industry is highly fragmented, consisting of a large
number of small, specialized companies and a limited number of well-capitalized
companies. The Company competes in product specific markets which it estimates
range in size from $10 million to $100 million in annual revenues. The Company
believes that the small size of its markets, combined with the industry's
stringent regulatory approvals and the need to make significant investments in
research and development reduces the risk of new entrants. Management believes
its markets are too small to attract large aerospace companies. In addition,
management believes the financial resources and technical expertise required to
compete in these markets are beyond the reach of most small companies. Finally
all potential competitors must meet the certification requirements and
qualification approvals required by the FAA and aircraft OEMs.
 
                                       46
<PAGE>
    AFTERMARKET
 
    Aircraft components need to be serviced regularly to meet FAA standards and
aircraft reliability requirements. Demand for aftermarket parts depends on
revenue passenger miles and, to a lesser extent, on airline profitability, each
of which has historically been correlated with changes in general economic
conditions, and the size and age of the worldwide aircraft fleet. Since certain
modern aircraft can have useful lives of 30 years or more, spare parts and
repair and overhaul services can often generate more sales than the OEM program
at significantly higher margins. Management further believes that aftermarket
sales help to offset declines in OEM demand as historically airlines and air
cargo operators have increased repair and overhaul spending to prolong the life
of older aircraft when they delay purchasing new aircraft. Customers in the
aftermarket segment include airlines, air cargo operators, aircraft leasing
companies, corporate and individual owners of aircraft as well as maintenance,
repair and overhaul facilities and various agencies of the United States
government, including the military. Management believes that aftermarket sales
will continue to be an attractive market as a result of the following factors:
 
- - Air travel traffic continues to increase. In the United States, large
  commercial transport revenue passenger miles have increased from approximately
  431 billion in 1987 to approximately 604 billion in 1997, with 1991
  representing the only year in the last ten years in which annual revenue
  passenger miles decreased. On a worldwide basis, revenue passenger miles have
  increased from approximately 978 billion in 1985 to 1,719 billion in 1996.
 
- - Total aircraft fleet size has continued to increase despite the volatility of
  orders and deliveries. At the end of 1997 the large commercial aircraft fleet
  consisted of approximately 11,900 aircraft, a 4.5% compound annual increase
  from approximately 7,700 aircraft in 1987. Similarly, the regional aircraft
  fleet (consisting of turbo-prop and jet aircraft) has increased from
  approximately 4,900 units in 1987 to approximately 7,500 units in 1997 and the
  business aircraft fleet has increased from approximately 6,100 units in 1987
  to approximately 8,700 units in 1997.
 
- - Aircraft capacity utilization remains at high levels. Passenger load factors
  (measured as the percentage of occupied seats per flight) for U.S. carriers
  have increased from 62% in 1987 to 68% in 1996, a record for the industry.
  During 1997, carriers achieved 69% load factors on a worldwide basis.
 
    OEM
 
    Demand for OEM components depends on new aircraft deliveries. Demand for new
aircraft is a function of (i) demand for air travel, (ii) aircraft operator
profitability, (iii) fleet age, (iii) regulatory mandates such as noise
reduction, and (iv) the lag time between order and delivery, which causes
airlines to order aircraft according to perceived future need.
 
- - In the early 1990's, many airlines significantly reduced spending on new
  aircraft and extended the average age of their fleets due to weakened
  financial performance. With the return of airline profitability, commercial
  OEMs have experienced a surge in aircraft orders and deliveries which resulted
  in large commercial transport deliveries growing from a low of 370 aircraft in
  1995 to estimated 774 aircraft by the end of 1998.
 
- - The regional jet aircraft market has grown significantly in recent years as
  turbo-jet powered aircraft have made substantial inroads in a market
  traditionally served by the turboprop powered aircraft and some smaller
  commercial transports. Regional jets have greater range, faster speed and
  lower noise levels and are perceived as safer and more comfortable by
  passengers. U.S. regional revenue passenger miles have increased from
  approximately 4.0 billion miles in 1987 to approximately 7.7 billion miles in
  1996. Regional aircraft deliveries have increased significantly to 115 in 1997
  since
 
                                       47
<PAGE>
  their introduction in 1988. Industry forecasts by the U.S. Regional Airline
  Association concluded that approximately 1,280 regional and commuter aircraft
  will be delivered between 1998 and 2008.
 
- - The business jet market is driven by, among other factors, the increasing
  popularity of fractional ownership and the increasing demand for more
  expedient and convenient travel. Deliveries of executive jets have increased
  significantly since 1987.
 
- - The FAA has mandated that aircraft flying in U.S. airspace comply with Stage 3
  noise standards by December 31, 1999. Other countries, particularly in Western
  Europe, have instituted similar restrictions. As a result, it is expected that
  there will be an increased demand for aircraft during the next several years
  as the aircraft which are not retrofitted with "hush kits" are replaced.
 
- - While military spending for new aircraft has significantly declined with the
  end of the cold war, military parts and repair spending has been relatively
  stable for the last several years as existing platforms require parts to
  remain operational.
 
COMPETITIVE STRENGTHS
 
    The Company believes that its key competitive strengths are:
 
- - LARGE INSTALLED PRODUCT BASE AND RECURRING REVENUE STREAM. Management believes
  that approximately 70% of the Company's sales are derived from parts for which
  it has achieved sole source designation and approximately 80% of the Company's
  products are of proprietary design. As a result, the Company has a large and
  growing installed base of products on large commercial transport and regional,
  business and military platforms. This installed base affords the Company the
  opportunity to capture a long-term stream of highly profitable aftermarket
  revenues. Over the life of an aircraft, sales of replacement parts can
  generate revenues many times the size of the original OEM purchases.
  Aftermarket sales generate most of the Company's EBITDA, As Defined because
  they typically carry gross margins that are significantly higher than those
  generated from OEM sales.
 
- - PROVEN ABILITY TO DEVELOP NEW PRODUCTS. TransDigm has a successful record of
  introducing solutions-oriented products. The Company works closely with
  aircraft operators and OEMs to identify their unmet needs, such as a component
  that fails to meet performance expectations or that requires excessive
  maintenance. The Company then utilizes its engineering and design capabilities
  to develop a prototype for a component that increases the value of the product
  to the customer. After rigorous testing requirements have been fulfilled and
  the Company has obtained necessary regulatory approvals, the product is made
  available for sale in the aftermarket and to OEMs. Management believes that
  its ability to successfully develop new products has contributed to its
  significant growth.
 
- - DIVERSIFIED BUSINESS MIX. The Company's business is fairly evenly distributed
  between sales in the aftermarket and sales to OEMs. Each of these segments are
  further distributed among the large commercial transport and regional,
  business and military aircraft markets. As a result, the Company is not overly
  dependent on any one segment, with the large commercial transport OEM market
  accounting for less than 20% of sales in fiscal 1998.
 
- - LEADING POSITIONS IN NICHE MARKETS. With over 40 years of experience in most
  of its product lines, the Company has well-established and highly regarded
  products and trade names, such as "Adel," "Wiggins," "Controlex," "Marathon"
  and "SuperPower," and is a leader in many of its product lines. For example,
  the Company believes that it is the leading supplier of tube connectors for
  use in the flexible fluid systems found on most aircraft platforms.
 
- - EXPERIENCED AND INCENTIVIZED MANAGEMENT TEAM. TransDigm's management team
  collectively has over 125 years of industry experience and brings a
  disciplined approach to the business. Management has a proven track record of
  consolidating operations, reducing overhead and rationalizing costs. Since the
  Company was created in 1993, management has successfully integrated four
  distinct operating
 
                                       48
<PAGE>
  divisions and formed AdelWiggins and AeroControlex. Most recently management
  has successfully integrated Marathon into the Company. The management team has
  dramatically improved the operating performance and strategic position of
  TransDigm. EBITDA, As Defined margins have improved from 19.0% in fiscal 1994
  to 39.3% in fiscal 1998. In addition, management owns approximately 12.5% of
  the capital stock of Holdings on a fully diluted basis, which amount is
  subject to an increase to approximately 21.3% if certain performance targets
  are met.
 
BUSINESS STRATEGY
 
    Key elements of TransDigm's strategy are:
 
- - PROVIDE VALUE ADDED PRODUCTS TO CUSTOMERS. The Company will continue to focus
  on marketing and manufacturing highly engineered products to customers that
  place a premium on the Company's capabilities. The Company has been effective
  in communicating to aircraft operators the value of the Company's products in
  terms of cost savings generated by their greater reliability and performance
  and reduced maintenance requirements. The Company's reputation for quality and
  sole supplier status for many parts has allowed it to achieve substantial
  gross margins on its aftermarket products. The Company intends to continue to
  develop and market high value added products that carry higher gross margins
  by emphasizing their benefits to the customer.
 
- - GENERATE NEW BUSINESS INITIATIVES. TransDigm has been successful in
  identifying and commercializing new business opportunities to drive revenue
  growth. The Company has been particularly effective in creating aftermarket
  opportunities by developing superior products to retrofit aircraft already in
  service. New business has contributed significantly to the Company's 14%
  compound annual net sales growth rate (excluding Marathon) since fiscal 1994,
  which the Company believes is well in excess of the industry average growth
  rate during the same period. The Company intends to continue to aggressively
  pursue growth opportunities through its new business initiatives.
 
- - REALIZE PRODUCTIVITY SAVINGS. Management will continue to focus on improving
  operating margins through manufacturing improvements and increases in employee
  productivity. Management has achieved significant increases in productivity
  since fiscal 1994. Manufacturing facilities have been rationalized and
  manufacturing and other business practices have been redesigned to maximize
  efficiency. For example, TransDigm encourages its employees through
  performance incentives to learn to operate multiple manufacturing stations in
  order to minimize overall labor costs. This initiative and others like it have
  enabled the Company to significantly increase sales without material increases
  in headcount.
 
- - PURSUE STRATEGIC ACQUISITIONS. The Company intends to aggressively pursue
  acquisitions where it believes that it can enhance value, reduce costs and
  develop new business. The aircraft component industry is highly fragmented,
  with many of the companies in the industry being owned by small operators. The
  Company believes the industry is experiencing consolidation due to customer
  requirements, inherent economies of scale and technological advancements that
  favor more sophisticated competitors. The Company completed the Marathon
  acquisition in August 1997. The Company regularly engages in discussions with
  respect to other acquisition and investment opportunities. See the section
  "Risk Factors" under the heading "Risk Related to Potential Future
  Acquisitions."
 
OPERATING GROUPS
 
    TransDigm was formed in 1993 through a management-led buyout of IMO.
TransDigm operates three business units: Adelwiggins, AeroControlex and
Marathon. AdelWiggins, which is located in Los Angeles, CA and had 177 full time
employees at September 30, 1998, manufactures an extensive line of proprietary
fuel and hydraulic system connectors and specialized clamps, heaters and
refueling systems. AdelWiggins was formed in 1994 from the consolidation of the
Adel Fasteners and Wiggins Connectors
 
                                       49
<PAGE>
divisions acquired from IMO. Founded in 1938 and 1925, respectively, both Adel
Fasteners and Wiggins Connectors have had a long history in the aircraft
components industry and enjoy strong brand name recognition.
 
    AeroControlex, which is located in Cleveland, OH and had 183 full-time
employees at September 30, 1998, manufactures proprietary pumps, compressors,
valves, couplings and mechanical controls for commercial and military aircraft
and marine applications. AeroControlex was formed in 1994 from the consolidation
of the Aeroproducts and Controlex divisions acquired from IMO.
 
    Marathon, which is located Waco, TX and had 178 full-time employees at
September 30, 1998, was acquired by TransDigm in August 1997 as a strategic
addition to its AdelWiggins and AeroControlex business lines. Marathon has been
a leading manufacturer of nickel-cadmium batteries and static inverters to the
aerospace industry since its founding in 1923. Management has successfully
integrated the Marathon business unit into the TransDigm culture and believes
that, over the next several years, Marathon offers upside potential similar to
that achieved with the integration of AdelWiggins and AeroControlex.
 
PRODUCTS
 
    TransDigm's products are found on virtually all types of aircraft, and the
Company supplies components to all major domestic and international airlines.
Management estimates that over 80% of the Company's products are of proprietary
design and approximately 70% of the Company's sales are derived from parts for
which it has achieved sole source designation. The Company's products are
grouped into eleven major product lines, each of which is profitable and is
operated as a semiautonomous business unit.
 
    Much of the Company's recent success has been due to its identification and
development of new products for sale in the commercial aftermarket. The Company
works closely with customers to identify their unmet needs, such as a component
that fails to meet performance expectations or that requires excessive
maintenance. The Company then utilizes its engineering and design capabilities
to develop a prototype for a component that increases value of the product to
the customer. After rigorous testing requirements have been fulfilled and the
Company has obtained necessary regulatory approvals, the product is made
available for sale in the aftermarket and to OEMs.
 
    ADELWIGGINS.  Adelwiggins manufactures over 8,000 SKUs, representing 40% of
the Company's sales for fiscal 1998, which constitute five of the Company's
eleven major product lines: (i) flexible tube connectors, (ii) special
connectors, (iii) Adel clamps, (iv) Wiggins service systems and (v) heaters and
hoses. Tube connectors are fluid line connectors that provide leak tight joints
and are found in flexible fluid systems on most aircraft platforms including
fuel, water, waste and environmental systems. Special connectors are connectors
designed to allow breaking and reconnecting of fluid lines under pressure and
are found in quick disconnect applications including refueling and other fluid
management systems for military, space and rocket launch applications and in
frangible connectors for large commercial transports. Adel clamps include
cushioned clamps, engineered elastomers, bare metal clamps, clampshells, block
clamps and quick release clamps used to support fuel, hydraulic, fluid and
electric lines and are found in a broad variety of clamps located throughout the
airplane, including in engines to address high temperature and high vibration
requirements. Wiggins service systems include proprietary refueling nozzles and
systems, vents, receivers and quick disconnects and are found in mine refueling
equipment and military applications such as tanks and armored vehicles that
require high flow capabilities and universal compatibility. Heaters and hoses
consists of specialized hoses and heaters, including blanket and ribbon heaters,
heater cuffs, heated nipples and gaskets and heated tanks throughout the
aircraft and are designed to prevent freezing of fluids such as potable water
and waste and to provide heat for hot water service applications.
 
                                       50
<PAGE>
    AdelWiggins designs its products specifically to meet the engineering
requirements of its customers, focusing on aspects such as: reduced-profile or
low-profile geometry, broad ranges of high-temperature service, ease of
installation and, where possible, utilization of advanced materials to maximize
the strength-to-weight ratios of its components. These factors are critical to
both OEMs and commercial airlines given their emphasis on reducing both
acquisition and operating costs. In addition, the Company believes AdelWiggins'
products have a reputation for long service lives and extremely high reliability
in stressful operating environments.
 
    Approximately 60% of AdelWiggins' products are proprietary products designed
to meet specific customer needs. The remaining 40% are industry standard
designs. Roughly 55% of AdelWiggins' products are sole sourced, which is
advantageous to the Company because it creates significant switching costs
associated with the development and qualification of alternative engineered
solutions. This sole sourced status has contributed to AdelWiggins achieving
aftermarket sales of 30% of its net sales in fiscal 1998. See
"Business--Customers."
 
    AEROCONTROLEX.  AeroControlex manufactures over 13,000 SKUs, representing
39% of the Company's sales for fiscal 1998, which constitute three of the
Company's eleven major product lines: (i) mechanical controls, (ii) pumps and
(iii) valves and quick disconnects. Mechanical controls include
electromechanical control systems, sliding and ball bearing control cables and
gearboxes which are found in the lavatory drain, throttle control, engine
feedback, landing gear release and in ejection seats and fuel and air systems.
Pumps primarily include gear pumps which are found in hydraulic and fuel systems
applications. Valves and quick disconnects include fuel and air system valves,
compressors and quick disconnects which are found in air conditioning packages
and fuel, radar and potable water systems.
 
    AeroControlex designs, manufactures and sells pumps, compressors, valves,
couplings and mechanical controls primarily for the commercial and military
aircraft markets. AeroControlex has developed a reputation for providing
high-quality, reliable products consistently delivered on time. AeroControlex
works closely with customers to leverage its engineering expertise to create
technical solutions to customer-specific problems. About 95% of AeroControlex
products are proprietary and over 90% are sold on a sole-source basis, which is
advantageous to the Company because its creates significant switching costs
associated with the development and qualification of alternative engineered
solutions. This sole sourced status has contributed to AeroControlex achieving
aftermarket sales of 68% of its net sales in fiscal 1998. See
"Business--Customers."
 
    MARATHON.  Marathon manufacturers over 5,000 SKUs, representing 21% of the
Company's sales for fiscal 1998, which constitute three of the Company's eleven
major product lines: (i) vented cell nickel-cadmium batteries, (ii) static
inverters and (iii) sealed cell nickel-cadmium batteries. Vented cell
nickel-cadmium batteries and sealed cell batteries are used for engine starting
and emergency power aboard various aircraft while static inverters convert
direct current to alternating current for use in applications such as flight
instrumentation and communication. Marathon products are used for numerous
military applications, such as the F-16, F-18, Blackhawk, Apache and Cobra
programs. Approximately 50% of Marathon's products have achieved sole sourcing
status with its customers.
 
    Marathon is one of the worlds leading manufacturers of vented cell
nickel-cadmium batteries, which require frequent maintenance, as individual
cells within a battery are replaced throughout the life of the battery.
Marathon, which manufactures and sells both entire batteries and individual
cells, realizes replacement revenue in the aftermarket throughout the life of
the battery as a result of its position as a sole source supplier of products
that accounted for over 50% of its sales. Over 95% of Marathon's sales are
proprietary, the status of which has contributed to Marathon achieving
aftermarket sales of 69% of its net sales in fiscal 1998. Vented cell batteries
are marketed under the Marathon-TM- and SuperPower-TM- brand names.
 
                                       51
<PAGE>
SALES AND MARKETING
 
    Consistent with the Company's overall strategy, the Company's sales and
marketing organization is structured to understand and anticipate the needs of
customers in order to continually develop a stream of technical solutions that
generate significant value. Particular focus is on the high-margin, repeatable
aftermarket segment.
 
    The Company has structured its sales efforts along its eleven major product
lines, assigning a Product Line Manager to each line. The Product Line Managers
are expected to grow the sales and profitability of their product line faster
than the served market and to achieve the targeted annual level of booking,
sales, new business and profitability for each product. Assisting the Product
Line Managers are Account Managers and Sales Engineers who are responsible for
covering both major OEM and airline accounts. They are expected to be familiar
with the personnel, organization and needs of specific customers, for achieving
total bookings and new business goals at each account, and, in conjunction with
the Product Line Managers, for determining when additional resources are
required at customer locations. All of the Company's sales personnel are
compensated in part on their bookings and sales and ability to identify and
convert new business opportunities.
 
    Though the majority are employees, the Account Manager function may be
performed by independent representatives depending on the specific customer,
product and geographic location. TransDigm also uses a limited number of
distributors to provide logistical support as well as primary customer contact
with certain smaller accounts. The Company's largest distributor is Aviall,
which provides logistic services to the commercial airlines.
 
MANUFACTURING AND ENGINEERING
 
    TransDigm maintains three manufacturing facilities. Each facility serves its
respective operating group, and comprises manufacturing, distribution and
engineering as well as corporate functions, including management, sales and
finance. The AdelWiggins, AeroControlex and Marathon facilities encompass
approximately 105,000, 44,000 and 150,000 square feet of manufacturing space in
Los Angeles, California, Cleveland, Ohio and Waco, Texas, respectively. In the
last several years, management has taken a number of steps to improve
productivity and reduce costs, including consolidating operations, developing
improved control systems that allow for accurate product line profit and loss
accounting, investing in equipment and tooling, installing modern information
systems and implementing a broad-based employee training program. Management
believes that the Company's manufacturing systems and equipment are critical
competitive factors that permit it to meet the rigorous tolerances and cost
sensitive price structure of aircraft customers. The Company concentrates in
manufacturing by product line, alternating its equipment among designs as demand
requires. TransDigm is in the process of applying its proven manufacturing
strategy to the Marathon facility, where its expects to be able to substantially
improve Marathon's performance.
 
    Each of the Company's operating groups attempts to differentiate itself from
its competitors by producing highly engineered products at a low cost. The
Company's proprietary products are designed by its engineering staff and
intended to serve an unmet need in the aircraft component industry, particularly
through its new product initiatives. See "--Products." These proprietary designs
must withstand the extraordinary conditions and stresses that will be endured by
products during use and meet the rigorous demands of the Company's customers
tolerance and quality requirements.
 
    The Company uses sophisticated equipment and procedures to ensure the
quality of its products and to comply with military specifications and FAA and
OEM certification requirements. The Company performs a variety of testing
procedures, including testing under different temperature, humidity and altitude
levels, shock and vibration testing and X-ray fluorescent measurement. These
procedures, together with other customer approved techniques for document,
process and quality control, are used throughout the Company's manufacturing
facilities.
 
                                       52
<PAGE>
CUSTOMERS
 
    TransDigm's customers include (i) commercial airlines (including national
and regional airlines), particularly for aftermarket MRO components, (ii) large
commercial transport and regional and business aircraft OEMs, (iii) various
agencies of the United States' government, including the United States military,
and (iv) various other industrial customers. The Company's three largest
customers for fiscal 1998, were Aviall (a distributor of aftermarket parts to
airlines throughout the world), Boeing (including McDonnell Douglas) and various
agencies of the United States' government, which accounted for approximately
20%, 14% and 9%, respectively, of the Company's net sales in fiscal 1998. The
Company's top ten customers accounted for approximately 61% of the Company's net
sales for fiscal 1998.
 
    The Company has strong customer relationships with virtually all important
large commercial transport, general aviation and military OEMs. The demand for
the Company's aftermarket parts and services is related to the Company's
extensive installed base and to revenue passenger miles and, to a lesser extent,
to airline profitability and the size and age of the worldwide aircraft fleet.
See "Business--Industry Overview." Some of the Company's business is executed
under long-term agreements with customers which encompass many products under a
common agreement. See "Risk Factors--Customer Contracts." The Company is also a
leading supplier of components used on United States' designed military
aircraft. The Company's products are used on a variety of fighter aircraft, and
helicopters. Military aircraft using the Company's products include the Lockheed
F-15 and F-16, the E2C (Hawkeye) and Blackhawk and Apache helicopters.
 
COMPETITION
 
    The Company competes with a number of established companies, including
divisions of larger companies, that have significantly greater financial,
technological and marketing resources than the Company. The niche markets within
the aerospace industry served by the Company are relatively fragmented with
several competitors for each of the products and services provided by each of
AdelWiggins, AeroControlex and Marathon. Due to the global nature of the
commercial aircraft industry, competition in these categories comes from both
U.S. and foreign companies. However, the Company knows of no single competitor
that provides the same range of products and services as those provided by the
Company. Competitors in the Company's product lines range in size from divisions
of large corporations to small privately held entitles, with only one or two
components in their entire product line. Certain of the Company's competitors
have significantly greater financial, technological and marketing resources than
the Company. The Company believes that its ability to compete depends
on high product performance, short lead-time and timely delivery, competitive
price, and superior customer service and support. There can be no assurance that
the Company will be able to compete successfully with respect to these or other
factors. See "Risk Factors--Competition."
 
GOVERNMENTAL REGULATION
 
    The commercial aircraft component industry is highly regulated by both the
FAA in the United States and by the Joint Aviation Authorities in Europe, while
the military aircraft component industry is governed by military quality
specifications. The Company, and the components it manufacturers, are required
to be certified by one or more of these entities, and, in some cases, by
individual OEMs in order to engineer and service parts and components used in
specific aircraft models. If material authorizations or approvals were revoked
or suspended, the operations of the Company would be adversely affected. In the
future, new and more stringent government regulations may be adopted, or
industry oversight may be heightened, which may have an adverse impact on the
Company.
 
    The Company must also satisfy the requirements of its customers, including
OEMs and airlines, that are subject to FAA regulations, and provide these
customers with products and services that
 
                                       53
<PAGE>
comply with the government regulations applicable to commercial flight
operations. In addition, the FAA requires that various maintenance routines be
performed on aircraft components, and the Company currently satisfies or exceeds
these maintenance standards in its repair and overhaul services. Several of the
Company's operating divisions include FAA-approved repair stations.
 
    The Company's operations are also subject to a variety of worker and
community safety laws. OSHA mandates general requirements for safe workplaces
for all employees. In addition, OSHA provides special procedures and measures
for the handling of certain hazardous and toxic substances. The Company believes
that its operations are in material compliance with OSHA's health and safety
requirement.
 
RAW MATERIALS AND PATENTS
 
    The components that the Company manufactures require the use of various raw
materials including titanium, aluminum, nickel powder, nickel screen, stainless
steel and cadmium, the availability and prices of which may fluctuate. The price
of raw materials and outside processing represents approximately 20% of the
sales price of the Company's products for fiscal 1998. Price increases in these
supplies may not be able to be recovered. The Company also purchases a variety
of manufactured component parts from various suppliers although the Company is
concentrating its orders among fewer suppliers to strengthen its supplier
relationships. Raw materials and component parts are generally available from
multiple suppliers at competitive prices. However, any delay in the Company's
ability to obtain necessary raw materials and component parts may affect its
ability to meet customer production needs.
 
    The Company has various trade secrets, proprietary information, trademarks,
trade names, patents, copyrights and other intellectual property rights which
the Company believes, in the aggregate (but not individually), are important to
its business.
 
ENVIRONMENTAL MATTERS
 
    The Company's operations and current and/or former facilities are subject to
federal, state and local environmental laws and to regulation by government
agencies, including the Environmental Protection Agency. Among other matters,
these regulatory authorities impose requirements that regulate the emission,
discharge, generation, management, transportation and disposal of hazardous
materials and pollutants, govern response actions to hazardous materials which
may be or have been released to the environment, and require the Company to
obtain and maintain permits in connection with its operations. The extensive
regulatory framework imposes significant compliance burdens and risks on the
Company. Although management believes that the Company's operations and its
facilities are in compliance in all material respects with applicable
environmental laws, there can be no assurance that future changes in such laws,
regulations or interpretations thereof or the nature of the Company's operations
will not require the Company to make significant additional expenditures to
ensure compliance in the future. Pursuant to certain environmental laws, a
current or previous owner or operator of real property may be liable for the
costs of investigations, removal or remediation of hazardous materials at such
property. Such laws typically impose liability whether or not the owner or
operator knew of, or was responsible for, the presence of such hazardous
materials. Persons who arrange, or are deemed to have arranged, for disposal or
treatment of hazardous materials also may be liable for the costs of
investigation, removal or remediation of such substances at the disposal or
treatment site, regardless of whether the affected site is owned or operated by
such person. Because the Company owns and/or operates a number of facilities,
and because the Company arranges for the disposal of hazardous materials at many
disposal sites, the Company may incur costs for investigation, removal and
remediation, as well as, capital costs associated with compliance. Although such
environmental costs have not been material in the past and are not expected to
be material in the future, there can be assurance that changes in environmental
laws or unexpected investigations and
 
                                       54
<PAGE>
clean-up costs will not be material. See "Risk Factors--Potential Exposure to
Environmental Liabilities." The Company does not currently contemplate material
capital expenditures for environmental compliance remediation for fiscal 1999 or
fiscal 2000.
 
    The soil and groundwater beneath the Company's facility in Waco, Texas, have
been impacted by releases of hazardous materials. Because the majority of the
contaminants identified to date are presently below action levels prescribed by
the Texas Natural Resources Conservation Commission ("TNRCC"), the Company does
not believe the condition of the soil and groundwater at the Waco facility will
require incurrence of material capital expenditures; however, there can be no
assurance that additional contamination will not be discovered or that the
remediation required by the TNRCC will not be material to the financial
condition, results of operations or cash flows of the Company.
 
PROPERTIES AND FACILITIES
 
    The Company owns and operates a 130,000 square foot facility in Los Angeles,
California, a 63,000 square foot facility in Cleveland, Ohio and a 219,000
square foot facility in Waco, Texas which is also the Company's headquarters.
The Company also leases certain of its other facilities. Management believes
that its machinery, plants and offices are in satisfactory operating condition,
and, upon completion of its planned 10,000-20,000 square foot expansion of the
AeroControlex manufacturing facility, will have sufficient capacity to meet
foreseeable future needs without incurring significant additional capital
expenditures.
 
EMPLOYEES
 
    As of September 30, 1998, the Company had approximately 540 full-time
employees and 45 temporary employees. Approximately 11% of the Company's
employees were represented by the United Steelworkers Union, and approximately
19% were represented by the United Automobile,
Aerospace and Agricultural Implement Workers of America. Collective bargaining
agreements between the Company and these labor unions expire on April 1999 and
November 2000, respectively. The Company considers its relationship with its
employees generally to be satisfactory and does not expect any difficulty in
reaching new collective bargaining agreements.
 
LEGAL PROCEEDINGS
 
    During the ordinary course of business, the Company is from time to time
threatened with, or may become a party to, legal actions and other proceedings.
While the Company is currently involved in certain legal proceedings, management
believes the results of these proceedings will not have a material effect of the
results of operations of the Company, in part due to certain indemnification
arrangements. The Company believes that its potential exposure to such legal
actions is adequately covered by its aviation product and general liability
insurance.

MANAGEMENT STOCKHOLDERS AGREEMENT
 
    In connection with the consummation of the Recapitalization, Holdings,
Odyssey and the employee stockholders of Holdings, including the Named Executive
Officers (the "Management Stockholders") entered into a Management Stockholders'
Agreement (the "Management Stockholders' Agreement") which governs the shares of
common stock of Holdings (the "Common Stock") and options to purchase Common
Stock, in each case, held by such persons (including the Rollover Investment and
new options and shares obtained in connection with the Recapitalization) and
shares acquired upon exercise of options. See "--Stock Option Plan."
 
    The Management Stockholders' Agreement provides that, except for certain
transfers to family members and family trusts, no Management Stockholder may
transfer Common Stock until the fifth anniversary of the Recapitalization, and
thereafter, any proposed transfer will be subject to Holdings' right of first
refusal.
 
    The Management Stockholders' Agreement also provides that upon termination
of the employment of a Management Stockholder, such Management Stockholder will
have certain put rights and Holdings will have certain call rights regarding his
or her Common Stock.
 
    Upon Mr. Peacock's cessation of active service as Chief Executive Officer on
or after the third anniversary of the Recapitalization (see "--Employment
Agreements"), if the Company has achieved specified financial targets, he may
require Holdings to repurchase up to 80% of his Common Stock during the period,
if any, for which he is serving as non-executive Chairman of the Board. Mr.
Peacock may thereafter require repurchase of the remaining 20% of his Common
Stock on or after the fifth anniversary of the Recapitalization or his later
termination of services to the Company. Holdings will be permitted to honor its
obligation to Mr. Peacock by issuing notes under certain circumstances.
 
    If the provisions of any law, the terms of credit and financing arrangements
or Holdings' financial circumstances would prevent Holdings from making a
repurchase of shares pursuant to the Management Stockholders' Agreement,
Holdings will not make such purchase until all such prohibitions lapse, and will
then also pay the Management Stockholder a specified rate of interest on the
repurchase price.
 
    The Management Stockholders' Agreement further provides that in the event of
certain transfers of Common Stock by Odyssey the Management Stockholders may
participate in such transfers and/or Odyssey may require the Management
Stockholders to transfer their shares in such transactions, in each case on a
pro rata basis.
 
    Pursuant to the Management Stockholders' Agreement, certain Management
Stockholders are entitled to participate on a pro rata basis with, and on the
same terms as, Odyssey in any future offering of Common Stock. Such
participation rights will lapse following a public offering of Common Stock.

EMPLOYMENT AGREEMENTS
 
    In connection with the Recapitalization, Holdings will enter into an
employment agreement with Mr. Peacock pursuant to which he will continue to
serve as Chairman of the Board and Chief Executive Officer for a period of at
least five years and with Mr. Howley pursuant to which he will continue to serve
as President and Chief Operating Officer of the Company for a period of at least
five years (together, the "Employment Agreements"). The Employment Agreements
also will provide specified severance benefits in the event of termination of
employment under certain circumstances.
 
    Each of the Employment Agreements will provide that in the event the
respective executive's employment terminates by reason of death, disability,
termination without "cause" or resignation with "good reason" (all as defined in
the Employment Agreements), Holdings will continue payment of base salary, bonus
and other perquisites and benefits, in the case of Mr. Howley, for 15 months
thereafter and, in the case of Mr. Peacock, for 18 months thereafter or, if
terminated prior to the third anniversary of the Recapitalization, until such
third anniversary, whichever is longer.
 
    Pursuant to the Employment Agreements, Messrs. Peacock and Howley will
receive annual base salaries no less than $330,000 and $225,000, respectively
(in each case, subject to annual increases as determined by the Compensation
Committee), and annual cash bonuses based on achievement of performance criteria
established by the Board of Directors. After three years, Mr. Peacock may elect
to continue his service either as Chief Executive Officer or as a non-executive
Chairman and it is intended that Mr. Howley will be his successor.
 
STOCK OPTION PLAN
 
    Holdings intends to adopt the 1998 Stock Option Plan (the "Option Plan"),
pursuant to which stock options may be granted to Independent Directors (as
defined in the Option Plan), employees and consultants of Holdings, the Company
and any subsidiary of Holdings or the Company (the "Plan Participants"). In
addition, the Option Plan will govern those options retained pursuant to the
Rollover Investment (the "Rollover Options"). A total of 10% of the fully
diluted shares of Common Stock of Holdings as of the Recapitalization was
reserved for issuance under the Option Plan (exclusive of the Rollover
Investment). The Chief Executive Officer will have discretion to select the Plan
Participants and to specify the terms of such options, including the number of
shares, the exercise price and the vesting and expiration of options, subject to
approval by the Compensation Committee.
 
    The Compensation Committee will have discretion under the Option Plan to
adjust options to reflect certain specified events such as stock dividends,
stock splits, recapitalizations, mergers or reorganizations of, or by Holdings.
In addition, the Board of Directors will have the right to amend, suspend or
terminate the Option Plan, subject to stockholder approval for certain
amendments.
 
    The Rollover Options are fully vested and nonforfeitable. In connection with
the Recapitalization, Holdings will grant options to certain employees of the
Company including the Named Executive Officers for the purchase of shares of
Common Stock of Holdings (the "New Options"). Such New Options are intended to
qualify as "incentive stock options" to the extent permitted under the Internal
Revenue Code, and will have an exercise price equal to the price per share paid
by Odyssey in connection with the Recapitalization. Twenty percent of each of
Messrs. Peacock's and Howley's New Options will become vested as of the date of
grant. Subject to the executive's continued employment with and, in the case of
Mr. Peacock, continued service as non executive Chairman of the Board of, the
Company, the remaining 80% of his New Options will become exercisable upon the
earlier of (1) the Company's achievement of specified financial targets or (2)
certain specified dates in the Option Agreement. Furthermore, in the event of a
"change of control" (as defined in the Option Agreement), a specified percentage
of the New Options may become exercisable based upon the terms of such
transaction. The New Options generally will expire 10 years after grant and may
expire earlier in the event of the executive's termination of employment.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
TAX ALLOCATION AGREEMENT
 
    The Company and Holdings entered into a Tax Allocation Agreement
concurrently with the consummation of the Recapitalization. Pursuant to such Tax
Allocation Agreement, the Company is obligated to make payments to Holdings
equal to the amount of income taxes that the Company would have owed in respect
of federal and state income taxes on behalf of the Company and its subsidiaries
if the Company and its subsidiaries were, for tax purposes, a separate
consolidated group.
 
ONE-TIME MANAGEMENT BONUSES
 
   
    Following the consummation of the Recapitalization, the Company paid certain
members of senior management an aggregate of $5.9 million as a one-time bonus in
connection with the Recapitalization. See "Management--Executive Compensation."
    
 
TERMINATION OF FINANCIAL ADVISORY SERVICES AGREEMENT
 
    The Company paid $6.0 million to Kelso & Company, an affiliate of Kelso, in
consideration for the termination of a Financial Advisory Services Agreement.
This payment was made upon consummation of the Recapitalization.
 
    Kelso may be deemed, collectively, to beneficially own 15.4% of the Common
Stock of Holdings on a fully diluted basis. In addition, Mr. Wall, a director of
Holdings and the Company, is a general partner of each of the Kelso entities.
 
KELSO STOCKHOLDERS AGREEMENT
 
    Pursuant to the Merger Agreement, Holdings, Odyssey and KIA IV-TD and KEP II
entered into a stockholders agreement (the "Stockholders Agreement")
concurrently with consummation of the Recapitalization. The Stockholders
Agreement provides for customary transfer restrictions, tag-along and drag-along
rights, registration rights and an agreement among the parties to vote their
shares of Common Stock, including the agreement of Odyssey to designate a
representative of Kelso to the Board of Directors of the Company. See also
"Management" for a description of certain agreements that have been entered into
with certain members of management in connection with the Recapitalization. See
"-Termination of Financial Advisory Services Agreement."
 
ODYSSEY FINANCIAL SERVICES
 
    In connection with the Recapitalization, the Company paid Odyssey a fee of
approximately $3.5 million. Odyssey is the majority stockholder of Holdings. In
addition, Messrs. Berger, Hopkins and Mirza, each a director of Holdings and the
Company, are managing members of the General Partner of Odyssey.
 
RECAPITALIZATION
 
    In connection with the Recapitalization and pursuant to the Merger
Agreement, Phase II Acquisition Corp., a wholly-owned subsidiary of Odyssey,
merged with and into Holdings.
 
    Also, in connection with the Recapitalization and as part of the
consideration for the Merger, Holdings (i) issued $20.0 million in Holdings PIK
Notes and common stock of Holdings and (ii) paid $215.4 million in cash, in each
case, to Kelso. See "Transactions," "--Odyssey Financial Services" and
"--Termination of Financial Advisory Services Agreement."

                       DESCRIPTION OF OTHER INDEBTEDNESS
 
THE COMPANY
 
    THE NEW CREDIT FACILITY
 
    The New Credit Facility consists of (i) a $30.0 million Revolving Credit
Facility maturing six years from the date of the execution of the New Credit
Facility (the "Execution Date") and (ii) a term loan facility in an aggregate
principal amount of $90.0 million, consisting of the $45.0 million Tranche A
Facility maturing six years from the Execution Date and the $45.0 million
Tranche B Facility maturing seven and a half years from the Execution Date.
 
    The New Credit Facility provides that the Company shall repay, to the extent
then outstanding, (i) with respect to the Tranche A Facility, the specified
amount set forth in the New Credit Facility for each quarter beginning on August
15, 1999 and (ii) with respect to the Tranche B Facility, (A) $225,000 each of
the first two quarters beginning on August 15, 1999, (B) $112,500 each of the
remaining quarters during the first six years after the Execution Date and (C)
$7,050,000 each of the following six quarters. In addition, subject to certain
limited exceptions, the New Credit Facility requires mandatory repayment of the
outstanding indebtedness thereunder (and reduction to the commitments
thereunder) with the proceeds from (i) assets sales, (ii) issuance of debt,
(iii) issuance of equity interests and capital contributions, (iv) insurance and
condemnation claims and (v) 50% of annual excess cash flow (as defined in the
New Credit Facility) from operations in excess of a predetermined amount, in
each case, by or of Holdings, the Company or their subsidiaries. The Company
will have the option at any time and from time to time to prepay the outstanding
indebtedness under the New Credit Facility without penalty or premium.
 
    Indebtedness under the New Credit Facility bears interest at the sum of the
(i) Applicable Margin and (ii) at the option of the Company either the Base Rate
or the Eurodollar Rate (as defined in the New Credit Facility). The "Base Rate"
means the higher of (i) the rate that Bankers Trust Company ("BTCo") announces
from time to time as its prime lending rate, as in effect from time to time, and
(ii) 1/2 of 1% in excess of the overnight federal funds rate. The "Applicable
Margin" means the percentage per annum equal to (i) in the case of Tranche A
Facility and Revolving Credit Facility, subject to quarterly step-downs to be
determined based on certain levels of financial performance, (A) bearing an
interest rate determined by the Base Rate, 2.50% and (B) bearing an interest
rate determined by the Eurodollar Rate, 3.50% and (ii) in the case of Tranche B
Facility (A) bearing an interest rate determined by the Base Rate, 3.00% and (B)
bearing an interest rate determined by the Eurodollar Rate, 4.00%.
 
    The New Credit Facility contains various covenants, customary for similar
credit facilities or otherwise appropriate under the circumstances, that (i)
restrict Holdings, the Company and their subsidiaries from various actions,
including, among others, mergers and sales of assets, use of proceeds, granting
of liens, incurrence of indebtedness, voluntary prepayment of indebtedness,
including the Old Notes and the New Notes, capital expenditures, paying
dividends, business activities, investments and acquisitions, transactions with
affiliates, certain restrictions affecting subsidiaries, voluntary prepayment of
other Indebtedness and amendments or modifications to instruments governing such
other Indebtedness and (ii) require the Company to achieve and maintain certain
financial covenants.
 
    The New Credit Facility includes events of default provisions that are
typical for senior credit facilities or otherwise appropriate under the
circumstances. All obligations under the New Credit Facility are guaranteed by
Holdings and each of the subsidiaries, direct and indirect, of the Company. The
indebtedness under the New Credit Facility are secured by a pledge of the stock
of the Company and all of its domestic subsidiaries and a perfected lien and
security interest in assets other than real estate (tangible and intangible) of
the Company, its direct and indirect subsidiaries and Holdings.

HOLDINGS
 
    HOLDINGS PIK NOTES
 
    Concurrently with the issuance of the Old Notes by the Company, Holdings
issued $20.0 million in aggregate face value of its pay-in-kind notes due 2009
(the "Holdings PIK Notes") to KIA IV-TD and KEP II in connection with the
Recapitalization. The Holdings PIK Notes were issued to KIA IV-TD and KEP II
together with shares of Common Stock of Holdings. The Holdings PIK Notes are
unsecured obligations of Holdings, subordinated to the guarantee of the New
Credit Facility by Holdings, but senior to the guarantee of each of the Old
Notes and the New Notes by Holdings.
 
    Interest on the Holdings PIK Notes accrues at an annual fixed rate of 12%
and is payable semiannually in the form of additional Holdings PIK Notes for
five years after their issuance. Thereafter, cash interest is payable
semi-annually commencing 2004. The Holdings PIK Notes are redeemable at the
option of Holdings, in whole or in part, at a price equal to 100% of the
principal amount thereof for five years after their issuance and thereafter at
the prices set forth in the indenture pursuant to which the Holdings PIK Notes
were issued (the "Holdings Indenture"). If Holdings experiences specific kinds
of changes in control, it must offer to repurchase the Holdings PIK Notes at a
price equal to 101% of the principal amount thereof.
 
    The Holdings PIK Notes contain certain covenants on a consolidated basis,
including covenants that limit (i) indebtedness, (ii) restricted payments, (iii)
distributions by subsidiaries, (iv) transactions with affiliates, (v) sales of
assets and subsidiary stock, (vi) dividend and other payment restrictions, and
(vii) mergers or consolidations. The Holdings PIK Notes contain customary events
of default and the holders of the Holdings PIK Notes have customary registration
rights commencing on the third anniversary of the closing date. The covenants
and default provisions in the Holdings Indenture are substantially similar to
those contained in the Indenture governing the Old Notes and the New Notes, but
are less restrictive in certain respects.

<PAGE>
                          DESCRIPTION OF THE NEW NOTES
 
    The Company will issue the New Notes under an indenture (the "Indenture")
among itself, the Guarantors and State Street Bank and Trust Company, as Trustee
(the "Trustee"). The following is a summary of the material provisions of the
Indenture. It does not include all of the provisions of the Indenture. We urge
you to read the Indenture because it defines your rights. The form and terms of
the New Notes will be the same as the form and terms of the Old Notes except
that the New Notes will be freely transferable by you except as otherwise
provided in this Prospectus. See "The Exchange Offer--Purpose and Effect". The
terms of the New Notes include those stated in the Indenture and those made part
of the Indenture by reference to the Trust Indenture Act of 1939 ("TIA") as in
effect on the date of the Indenture. A copy of the Indenture may be obtained
from the Company. You can find definitions of certain capitalized terms used in
the following summary under "--Certain Definitions." For purposes of this
section, references to (i) the "Company" mean TransDigm Inc. and not its
Subsidiaries or Holdings and (ii) the "Notes" mean the New Notes and the Old
Notes, in each case, outstanding at any given time and issued under the
Indenture.
 
    These New Notes will be unsecured obligations of the Company, ranking
subordinate in right of payment to all Senior Debt of the Company.
 
    The Company will issue the New Notes in fully registered form in
denominations of $1,000 and integral multiples of $1,000. The Trustee will
initially act as Paying Agent and Registrar. The New Notes may be presented for
registration of transfer and exchange at the offices of the Registrar. The
Company may change any Paying Agent and Registrar without notice to holders of
the New Notes (the "Holders"). The Company will pay principal (and premium, if
any) on the New Notes at the Trustee's corporate office in New York, New York.
At the Company's option, interest also may be paid by mailing a check to the
Holders registered address. Any Old Notes that remain outstanding after the
completion of the Exchange Offer, together with the New Notes issued in
connection with the Exchange Offer, will be treated as a single class of
securities under the Indenture.
 
PRINCIPAL, MATURITY AND INTEREST
 
    The Notes are limited in aggregate principal amount to $200.0 million, of
which up to $125.0 million in aggregate principal amount of the Notes will be
outstanding immediately following the Exchange Offer. The Notes will mature on
December 1, 2008. Additional Notes may be issued from time to time, subject to
the limitations set forth under "--Certain Covenants--Limitation on Incurrence
of Additional Indebtedness." Interest on the Notes will accrue at the rate of
10 3/8% per annum and will be payable semiannually in cash on each June 1 and
December 1, commencing on June 1, 1999. The Company will make interest payments
to the persons who are registered Holders at the close of business on the May 15
and November 15 immediately preceding the applicable interest payment date.
Interest on the New Notes will accrue from December 3, 1998 or from the date of
the last payment of interest on the Old Notes, whichever is later. No additional
interest will be paid on Old Notes tendered and accepted for exchange..
 
    The Notes do not contain any mandatory sinking fund.
 
REDEMPTION
 
    OPTIONAL REDEMPTION.  Except as described below, these New Notes are not
redeemable before December 1, 2003. Thereafter, the Company may redeem the New
Notes at its option, in whole or in part, upon not less than 30 nor more than 60
days' notice, at the following redemption prices
 
                                       66

(expressed as percentages of the principal amount thereof) if redeemed during
the twelve month period commencing on December 1 of the year set forth below.

2006 and thereafter...............................................................     100.000%
</TABLE>
 
    In addition, the Company must pay all accrued and unpaid interest on the
Notes redeemed.
 
    OPTIONAL REDEMPTION UPON EQUITY OFFERINGS.  On one or more occasions prior
to December 1, 2001, the Company may use the net cash proceeds of one or more
Equity Offerings to redeem up to 35% of the principal amount of the Notes
(including the New Notes) issued under the Indenture at a redemption price of
110.375% of the principal amount thereof plus accrued and unpaid interest
thereon, if any, to the date of redemption; PROVIDED that:
 
(1) at least 65% of the aggregate principal amount of Notes issued under the
    Indenture remains outstanding immediately after any such redemption; and
 
(2) the Company makes such redemption not more than 120 days after the
    consummation of such Equity Offering.
 
SELECTION AND NOTICE OF REDEMPTION
 
    In the event that the Company chooses to redeem less than all of the Notes,
selection of the Notes for redemption will be made by the Trustee either:
 
(1) in compliance with the requirements of the principal national securities
    exchange, if any, on which such Notes are listed; or
 
(2) on a PRO RATA basis, by lot or by such method as the Trustee shall deem fair
    and appropriate. No Notes of a principal amount of $1,000 or less shall be
    redeemed in part.
 
    If a partial redemption is made with the proceeds of an Equity Offering, the
Trustee will select the Notes only on a PRO RATA basis or on as nearly a PRO
RATA basis as is practicable. Notice of redemption will be mailed by first-class
mail at least 30 but not more than 60 days before the redemption date to each
Holder of Notes to be redeemed at its registered address. On and after the
redemption date, interest will cease to accrue on Notes or portions thereof
called for redemption as long as the Company has deposited with the Paying Agent
funds in satisfaction of the applicable redemption price.
 
SUBORDINATION
 
    The payment of all Obligations on the Notes is subordinated in right of
payment to the prior payment in full in cash or Cash Equivalents of all
Obligations on Senior Debt of the Company including its obligations under the
New Credit Facility.
 
    The holders of Senior Debt will be entitled to receive payment in full in
cash of all Obligations due in respect of Senior Debt (including interest after
the commencement of any bankruptcy or other like proceeding at the rate
specified in the applicable Senior Debt whether or not such interest is an
allowed claim in any such proceeding) before the Holders of Notes will be
entitled to receive any payment with respect to the Notes in the event of any
distribution to creditors of the Company:
 
(1) in a liquidation or dissolution of the Company;
 
(2) in a bankruptcy, reorganization, insolvency, receivership or similar
    proceeding relating to the Company or its property;
 
                                       67
<PAGE>
(3) in an assignment for the benefit of creditors; or
 
(4) in any marshalling of the Company's assets and liabilities.
 
    The Company also may not make any payment in respect of the Notes if:
 
(1) a payment default on Designated Senior Debt occurs and is continuing; or
 
(2) any other default occurs and is continuing on Designated Senior Debt that
    permits holders of the Designated Senior Debt to accelerate its maturity and
    the Trustee receives a notice of such default (a "Payment Blockage Notice")
    from the Representative of any Designated Senior Debt.
 
    Payments on the Notes may and shall be resumed:
 
(1) in the case of a payment default, upon the date on which such default is
    cured or waived; and
 
(2) in case of a nonpayment default, the earlier of the date on which such
    nonpayment default is cured or waived (so long as no other event of default
    exists) or 180 days after the date on which the applicable Payment Blockage
    Notice is received, unless the maturity of any Designated Senior Debt has
    been accelerated.
 
    No new Payment Blockage Notice may be delivered unless and until 360 days
have elapsed since the effectiveness of the immediately prior Payment Blockage
Notice.
 
    No nonpayment default that existed or was continuing on the date of delivery
of any Payment Blockage Notice to the Trustee shall be, or be made, the basis
for a subsequent Payment Blockage Notice unless such default shall have been
cured or waived for a period of not less than 90 days.
 
    The Company must promptly notify holders of Senior Debt if payment of the
Notes is accelerated because of an Event of Default.
 
    As a result of the subordination provisions described above, in the event of
a bankruptcy, liquidation or reorganization of the Company, Holders of these
Notes may recover less ratably than creditors of the Company who are holders of
Senior Debt. See "Risk Factors--Subordination."
 
    At September 30, 1998, on a pro forma basis after giving effect to the
Transactions, the aggregate principal amount of Senior Debt outstanding of the
Company and Holdings would have been $93.1 million and $113.1 million,
respectively.
 
GUARANTEE
 
    The obligations of the Company under the Notes and the Indenture will be
guaranteed (the "Guarantees") on a senior subordinated basis by Holdings and the
Domestic Restricted Subsidiaries. The Guarantees will be subordinated in right
of payment to all Senior Debt of Holdings and the Domestic Restricted
Subsidiaries, respectively, to the same extent that the Notes are subordinated
to Senior Debt of the Company. Since Holdings is a holding company with no
significant operations, the Guarantee by Holdings provides little, if any,
additional credit support for the Notes, and investors should not rely on the
Guarantee by Holdings in evaluating an investment in the Notes.
 
CHANGE OF CONTROL
 
    If a Change of Control occurs, each Holder will have the right to require
that the Company purchase all or a portion of such Holder's Notes pursuant to
the offer described below (the "Change of Control Offer"), at a purchase price
equal to 101% of the principal amount thereof plus accrued interest to the date
of purchase. Within 30 days following the date upon which the Change of Control
occurred, the Company must send, by first class mail, a notice to each Holder,
which notice shall govern the terms of the Change of Control Offer. Such notice
shall state, among other things, the purchase date, which must be no earlier
than 30 days nor later than 60 days from the date such notice
 
                                       68
<PAGE>
is mailed, other than as may be required by law (the "Change of Control Payment
Date"). Holders electing to have a Note purchased pursuant to a Change of
Control Offer will be required to surrender the Note, with the form entitled
"Option of Holder to Elect Purchase" on the reverse of the Note completed, to
the Paying Agent at the address specified in the notice prior to the close of
business on the third business day prior to the Change of Control Payment Date.
 
    Prior to the mailing of the notice referred to above, but in any event
within 30 days following any Change of Control, the Company covenants to:
 
(1) repay in full all Indebtedness under the New Credit Facility and all other
    Senior Debt the terms of which require repayment upon a Change of Control;
    or
 
(2) obtain the requisite consents under the New Credit Facility and all such
    other Senior Debt to permit the repurchase of the Notes as provided below.
    The Company's failure to comply with the covenant described in the
    immediately preceding sentence shall constitute an Event of Default
    described in clause (3) and not in clause (2) under "Events of Default"
    below.
 
    The Company will not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer in the
manner in compliance with the Indenture.
 
    If a Change of Control Offer is made, there can be no assurance that the
Company will have available funds sufficient to pay the Change of Control
purchase price for all the Notes that might be delivered by Holders seeking to
accept the Change of Control Offer. In the event the Company is required to
purchase outstanding Notes pursuant to a Change of Control Offer, the Company
expects that it would seek third party financing to the extent it does not have
available funds to meet its purchase obligations. However, there can be no
assurance that the Company would be able to obtain such financing.
 
    You should note that this provision will not protect you from the adverse
aspects of a highly leveraged transaction, reorganization, restructuring, merger
or similar transaction.
 
    The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act to the extent such laws and regulations are applicable in
connection with the repurchase of Notes pursuant to a Change of Control Offer.
To the extent that the Company complies with the provisions of any such
securities laws or regulations, the Company shall not be deemed to have breached
its obligations under the "Change of Control" provisions of the Indenture.
 
CERTAIN COVENANTS
 
    The Indenture contains, among others, the following covenants:
 
    LIMITATION ON INCURRENCE OF ADDITIONAL INDEBTEDNESS.  The Company will not,
and will not permit any of its Restricted Subsidiaries to, directly or
indirectly, create, incur, assume, guarantee, acquire, become liable,
contingently or otherwise, with respect to, or otherwise become responsible for
payment of (collectively "incur") any Indebtedness (other than Permitted
Indebtedness); PROVIDED, HOWEVER, that if no Default or Event of Default shall
have occurred and be continuing at the time of or as a consequence of the
incurrence of any such Indebtedness, the Company and the Guarantors may incur
Indebtedness (including, without limitation, Acquired Indebtedness) and
Restricted Subsidiaries of the Company that are not Guarantors may incur
Acquired Indebtedness, in each case if on the date of the incurrence of such
Indebtedness, after giving effect to the incurrence thereof, the Consolidated
Fixed Charge Coverage Ratio of the Company would have been greater than 2.0 to
1.0.
 
    LIMITATION ON RESTRICTED PAYMENTS.  The Company will not, and will not cause
or permit any of its Restricted Subsidiaries to, directly or indirectly:
 
                                       69

    respect of shares of the Company's Capital Stock to holders of such Capital
    Stock;
 
(2) purchase, redeem or otherwise acquire or retire for value any Capital Stock
    of the Company or any direct or indirect parent of the Company or any

(3) make any principal payment on, purchase, defease, redeem, prepay, decrease

(4) make any Investment (other than Permitted Investments) (each of the
    foregoing actions set forth in clauses (1), (2), (3) and (4) being referred

if at the time of such Restricted Payment or immediately after giving effect
thereto:
 
 (i) a Default or an Event of Default shall have occurred and be continuing; or
 
 (ii) the Company is not able to incur at least $1.00 of additional Indebtedness
      (other than Permitted Indebtedness) in compliance with the "Limitation on
      Incurrence of Additional Indebtedness" covenant; or
 
(iii) the aggregate amount of Restricted Payments (including such proposed
      Restricted Payment) made subsequent to the Issue Date (other than
      Restricted Payments made pursuant to clauses (2)(i), (3), (4), (5), (6),
      (7), (8), (9) and (10) of the following paragraph) shall exceed the sum,
      without duplication, of:
 
    (w) 50% of the cumulative Consolidated Net Income (or if cumulative
       Consolidated Net Income shall be a loss, minus 100% of such loss) of the
       Company earned subsequent to the beginning of the first fiscal quarter
       commencing after the Issue Date and on or prior to the date the
       Restricted Payment occurs (the "Reference Date") (treating such period as
       a single accounting period); plus
 
    (x) 100% of the aggregate net cash proceeds (including the fair market value
       of property other than cash that would constitute Marketable Securities
       or a Permitted Business) received by the Company from any Person (other
       than a Subsidiary of the Company) from the issuance and sale subsequent
       to the Issue Date and on or prior to the Reference Date of Qualified
       Capital Stock of the Company; plus
 
    (y) without duplication of any amounts included in clause (iii)(x) above,
       100% of the aggregate net cash proceeds of any equity contribution
       received by the Company from a holder of the Company's Capital Stock
       (excluding, in the case of clauses (iii)(x) and (y), any net cash
       proceeds from an Equity Offering to the extent used to redeem the Notes
       in compliance with the provisions set forth under "--Redemption--Optional
       Redemption Upon Equity Offerings"); plus

       property other than cash that would constitute Marketable Securities or a
       Permitted Business) of any (A) sale or other disposition of any
       Investment (other than a Permitted Investment) made by the Company and
       its Restricted Subsidiaries or (B) dividend from, or the sale of the
       stock of, an Unrestricted Subsidiary.

<PAGE>
    Notwithstanding the foregoing, the provisions set forth in the immediately
preceding paragraph do not prohibit:
 
(1) the payment of any dividend or the consummation of any irrevocable
    redemption within 60 days after the date of declaration of such dividend or
    notice of such redemption if the dividend or payment of the redemption
    price, as the case may be, would have been permitted on the date of
    declaration or notice;
 
(2) if no Default or Event of Default shall have occurred and be continuing or
    shall occur as a consequence thereof, the acquisition of any shares of
    Capital Stock of the Company (the "Retired Capital Stock") either (i) solely
    in exchange for shares of Qualified Capital Stock of the Company (the
    "Refunding Capital Stock") or (ii) through the application of net proceeds
    of a substantially concurrent sale for cash (other than to a Subsidiary of
    the Company) of shares of Qualified Capital Stock of the Company and, in the
    case of subclause (i) of this clause (2), if immediately prior to the
    retirement of the Retired Capital Stock the declaration and payment of
    dividends thereon was permitted under clause (5) of this paragraph, the
    declaration and payment of dividends on the Refunding Capital Stock in an
    aggregate amount per year no greater than the aggregate amount of dividends
    per annum that was declarable and payable on such Retired Capital Stock
    immediately prior to such retirement; PROVIDED that at the time of the
    declaration of any such dividends on the Refunding Capital Stock, no Default
    or Event of Default shall have occurred and be continuing or would occur as
    a consequence thereof;
 
(3) if no Default or Event of Default shall have occurred and be continuing, the
    acquisition of any Indebtedness of the Company that is subordinate or junior
    in right of payment to the Notes either (i) solely in exchange for shares of
    Qualified Capital Stock of the Company, or (ii) through the application of
    net proceeds of a substantially concurrent sale for cash (other than to a
    Subsidiary of the Company) of (A) shares of Qualified Capital Stock of the
    Company or (B) Refinancing Indebtedness;
 
(4) if no Default or Event of Default shall have occurred and be continuing or
    would occur as a consequence thereof, the declaration and payment of
    dividends to holders of any class or series of Designated Preferred Stock
    (other than Disqualified Capital Stock) issued after the Issue Date
    (including, without limitation, the declaration and payment of dividends on
    Refunding Capital Stock in excess of the dividends declarable and payable
    thereon pursuant to clause (2) of this paragraph); PROVIDED that, at the
    time of such issuance, the Company, after giving effect to such issuance on
    a pro forma basis, would have had a Consolidated Fixed Charge Coverage Ratio
    of at least 2.0 to 1.0;
 
(5) payments to Holdings for the purpose of permitting, and in an amount equal
    to the amount required to permit, Holdings to redeem or repurchase Holdings'
    common equity or options in respect thereof, in each case in connection with
    the repurchase provisions of employee stock option or stock purchase
    agreements or other agreements to compensate management employees; PROVIDED
    that all such redemptions or repurchases pursuant to this clause (5) shall
    not exceed $2.0 million in any fiscal year (which amount shall be increased
    by the amount of any net cash proceeds received from the sale since the
    Issue Date of Capital Stock (other than Disqualified Capital Stock) to
    members of the Company's management team that have not otherwise been
    applied to the payment of Restricted Payments pursuant to the terms of
    clause (iii) of the immediately preceding paragraph and by the cash proceeds
    of any "key-man" life insurance policies which are used to make such
    redemptions or repurchases) since the Issue Date; PROVIDED, FURTHER, that
    the cancellation of Indebtedness owing to the Company from members of
    management of the Company or any of its Restricted Subsidiaries in
    connection with any repurchase of Capital Stock of Holdings (or warrants or
    options or rights to acquire such Capital Stock) will not be deemed to
    constitute a Restricted Payment under the Indenture;
 
                                       71
<PAGE>
(6) the making of distributions, loans or advances to Holdings in an amount not
    to exceed $1.0 million PER ANNUM in order to permit Holdings to pay the
    ordinary operating expenses of Holdings (including, without limitation,
    directors' fees, indemnification obligations, professional fees and
    expenses);
 
(7) payments to Holdings in respect of taxes pursuant to the terms of the Tax
    Allocation Agreement as in effect on the Issue Date and as amended from time
    to time pursuant to amendments that do not increase the amounts payable by
    the Company or any of its Restricted Subsidiaries thereunder;
 
(8) repurchases of Capital Stock deemed to occur upon the exercise of stock
    options if such Capital Stock represents a portion of the exercise price
    thereof;
 
(9) other Restricted Payments in an aggregate amount not to exceed $7.5 million;
    and
 
(10) distributions to Holdings to fund the Transactions (as described under "Use
    of Proceeds") subsequent to the issuance of the Notes.
 
    In determining the aggregate amount of Restricted Payments made subsequent
to the Issue Date in accordance with clause (iii) of the immediately preceding
paragraph, (a) amounts expended pursuant to clauses (1) and (2)(ii) shall be
included in such calculation, PROVIDED such expenditures pursuant to clause (5)
shall not be included to the extent of the cash proceeds received by the Company
from any "key-man" life insurance policies and (b) amounts expended pursuant to
clauses (2)(i), (3), (4), (5), (6), (7), (8), (9) and (10) shall be excluded
from such calculation.
 
    LIMITATION ON ASSET SALES.  The Company will not, and will not permit any of
its Restricted Subsidiaries to, consummate an Asset Sale unless:
 
(1) the Company or the applicable Restricted Subsidiary, as the case may be,
    receives consideration at the time of such Asset Sale at least equal to the
    fair market value of the assets sold or otherwise disposed of (as determined
    in good faith by the Company's Board of Directors);
 
(2) at least 75% of the consideration received by the Company or the Restricted
    Subsidiary, as the case may be, from such Asset Sale shall be in the form of
    cash or Cash Equivalents and is received at the time of such disposition;
    PROVIDED that the amount of:
 
    (a) any liabilities (as shown on the Company's or such Restricted
       Subsidiary's most recent balance sheet) of the Company or any such
       Restricted Subsidiary (other than liabilities that are by their terms
       subordinated to the Notes) that are assumed by the transferee of any such
       assets;
 
    (b) any notes or other obligations received by the Company or any such
       Restricted Subsidiary from such transferee that are converted by the
       Company or such Restricted Subsidiary into cash within 90 days of the
       receipt thereof (to the extent of the cash received); and
 
    (c) any Designated Noncash Consideration received by the Company or any of
       its Restricted Subsidiaries in such Asset Sale having an aggregate fair
       market value, taken together with all other Designated Noncash
       Consideration received pursuant to this clause (c) that is at that time
       outstanding, not to exceed 5% of Total Assets at the time of the receipt
       of such Designated Noncash Consideration (with the fair market value of
       each item of Designated Noncash Consideration being measured at the time
       received and without giving effect to subsequent changes in value), shall
       be deemed to be cash for the purposes of this provision or for purposes
       of the second paragraph of this covenant; and
 
(3) upon the consummation of an Asset Sale, the Company shall apply, or cause
    such Restricted Subsidiary to apply, the Net Cash Proceeds relating to such
    Asset Sale within 365 days of receipt thereof either (A) to prepay any
    Senior Debt, or Indebtedness of a Restricted Subsidiary that is not a
    Guarantor and, in the case of any such Indebtedness under any revolving
    credit facility, effect a corresponding reduction in the availability under
    such revolving credit facility (or effect a
 
                                       72
<PAGE>
    permanent reduction in the availability under such revolving credit facility
    regardless of the fact that no prepayment is required in order to do so (in
    which case no prepayment should be required)), (B) to reinvest in Productive
    Assets, or (C) a combination of prepayment and investment permitted by the
    foregoing clauses (3)(A) and (3)(B). Pending the final application of any
    such Net Cash Proceeds, the Company or such Restricted Subsidiary may
    temporarily reduce Indebtedness under a revolving credit facility, if any,
    or otherwise invest such Net Cash Proceeds in Cash Equivalents. On the 366th
    day after an Asset Sale or such earlier date, if any, as the Board of
    Directors of the Company or of such Restricted Subsidiary determines not to
    apply the Net Cash Proceeds relating to such Asset Sale as set forth in
    clauses (3)(A), (3)(B) and (3)(C) of the preceding sentence (each, a "Net
    Proceeds Offer Trigger Date"), such aggregate amount of Net Cash Proceeds
    which have not been applied on or before such Net Proceeds Offer Trigger
    Date as permitted in clauses (3)(A), (3)(B) and (3)(C) of the next preceding
    sentence (each a "Net Proceeds Offer Amount") shall be applied by the
    Company or such Restricted Subsidiary to make an offer to purchase (the "Net
    Proceeds Offer") on a date (the "Net Proceeds Offer Payment Date") not less
    than 30 nor more than 60 days following the applicable Net Proceeds Offer
    Trigger Date, from all Holders on a PRO RATA basis, the maximum amount of
    Notes that may be purchased with the Net Proceeds Offer Amount at a price
    equal to 100% of the principal amount of the Notes to be purchased, plus
    accrued and unpaid interest thereon, if any, to the date of purchase;
    PROVIDED, HOWEVER, that if at any time any non-cash consideration (including
    any Designated Noncash Consideration) received by the Company or any
    Restricted Subsidiary of the Company, as the case may be, in connection with
    any Asset Sale is converted into or sold or otherwise disposed of for cash
    (other than interest received with respect to any such non-cash
    consideration), then such conversion or disposition shall be deemed to
    constitute an Asset Sale hereunder and the Net Cash Proceeds thereof shall
    be applied in accordance with this covenant. Notwithstanding the foregoing,
    if a Net Proceeds Offer Amount is less than $10.0 million, the application
    of the Net Cash Proceeds constituting such Net Proceeds Offer Amount to a
    Net Proceeds Offer may be deferred until such time as such Net Proceeds
    Offer Amount plus the aggregate amount of all Net Proceeds Offer Amounts
    arising subsequent to the Net Proceeds Offer Trigger Date relating to such
    initial Net Proceeds Offer Amount from all Asset Sales by the Company and
    its Restricted Subsidiaries aggregates at least $10.0 million, at which time
    the Company or such Restricted Subsidiary shall apply all Net Cash Proceeds
    constituting all Net Proceeds Offer Amounts that have been so deferred to
    make a Net Proceeds Offer (the first date the aggregate of all such deferred
    Net Proceeds Offer Amounts is equal to $10.0 million or more shall be deemed
    to be a Net Proceeds Offer Trigger Date).
 
    Notwithstanding the immediately preceding paragraph, the Company and its
Restricted Subsidiaries will be permitted to consummate an Asset Sale without
complying with such paragraph to the extent that:
 
(1) at least 75% of the consideration for such Asset Sale constitutes Productive
    Assets, cash, Cash Equivalents and/or Marketable Securities; and
 
(2) such Asset Sale is for fair market value; PROVIDED that any consideration
    consisting of cash, Cash Equivalents and/or Marketable Securities received
    by the Company or any of its Restricted Subsidiaries in connection with any
    Asset Sale permitted to be consummated under this paragraph shall constitute
    Net Cash Proceeds subject to the provisions of the preceding paragraph.
 
    Each Net Proceeds Offer will be mailed to the record Holders as shown on the
register of Holders within 30 days following the Net Proceeds Offer Trigger
Date, with a copy to the Trustee, and shall comply with the procedures set forth
in the Indenture. Upon receiving notice of the Net Proceeds Offer, Holders may
elect to tender their Notes in whole or in part in integral multiples of $1,000
in exchange for cash. To the extent Holders properly tender Notes in an amount
exceeding the Net Proceeds Offer Amount, Notes of tendering Holders will be
purchased on a PRO RATA basis (based on
 
                                       73
<PAGE>
amounts tendered). A Net Proceeds Offer shall remain open for a period of 20
business days or such longer period as may be required by law. To the extent
that the aggregate amount of Notes tendered pursuant to a Net Proceeds Offer is
less than the Net Proceeds Offer Amount, the Company may use any remaining Net
Proceeds Offer Amount for general corporate purposes or for any other purpose
not prohibited by the Indenture. Upon completion of any such Net Proceeds Offer,
the Net Proceeds Offer Amount shall be reset at zero.
 
    The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of Notes pursuant to a Net Proceeds Offer. To the extent that the
provisions of any securities laws or regulations conflict with the "Asset Sale"
provisions of the Indenture, the Company shall comply with the applicable
securities laws and regulations and shall not be deemed to have breached its
obligations under the "Asset Sale" provisions of the Indenture by virtue
thereof.
 
    LIMITATION ON DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING
SUBSIDIARIES.  The Company will not, and will not cause or permit any of its
Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or
permit to exist or become effective any consensual encumbrance or consensual
restriction on the ability of any Restricted Subsidiary of the Company to:
 
(1) pay dividends or make any other distributions on or in respect of its
    Capital Stock;
 
(2) make loans or advances or pay any Indebtedness or other obligation owed to
    the Company or any other Restricted Subsidiary of the Company; or
 
(3) transfer any of its property or assets to the Company or any other
    Restricted Subsidiary of the Company, except for such encumbrances or
    restrictions existing under or by reason of:
 
    (a) applicable law;
 
    (b) the Indenture;
 
    (c) non-assignment provisions of any contract or any lease of any Restricted
       Subsidiary of the Company entered into in the ordinary course of
       business;
 
    (d) any instrument governing Acquired Indebtedness, which encumbrance or
       restriction is not applicable to any Person, or the properties or assets
       of any Person, other than the Person or the properties or assets of the
       Person so acquired;
 
    (e) the New Credit Facility;
 
    (f) agreements existing on the Issue Date to the extent and in the manner
       such agreements are in effect on the Issue Date;
 
    (g) restrictions on the transfer of assets subject to any Lien permitted
       under the Indenture imposed by the holder of such Lien;
 
    (h) restrictions imposed by any agreement to sell assets or Capital Stock
       permitted under the Indenture to any Person pending the closing of such
       sale;
 
    (i) any agreement or instrument governing Capital Stock of any Person that
       is acquired;
 
    (j) any Purchase Money Note or other Indebtedness or other contractual
       requirements of a Securitization Entity in connection with a Qualified
       Securitization Transaction; provided that such restrictions apply only to
       such Securitization Entity;
 
    (k) other Indebtedness or Permitted Subsidiary Preferred Stock outstanding
       on the Issue Date or permitted to be issued or incurred under the
       Indenture; PROVIDED that any such restrictions are
 
                                       74
<PAGE>
       ordinary and customary with respect to the type of Indebtedness being
       incurred or Preferred Stock being issued (under the relevant
       circumstances);
 
    (l) restrictions on cash or other deposits or net worth imposed by customers
       under contracts entered into in the ordinary course of business; and
 
    (m) any encumbrances or restrictions imposed by any amendments,
       modifications, restatements, renewals, increases, supplements,
       refundings, replacements or refinancings of the contracts, instruments or
       obligations referred to in clauses (a) through (l) above; PROVIDED that
       such amendments, modifications, restatements, renewals, increases,
       supplements, refundings, replacements or refinancings are, in the good
       faith judgment of the Company's Board of Directors (evidenced by a Board
       Resolution) whose judgment shall be conclusively binding, not materially
       more restrictive with respect to such dividend and other payment
       restrictions than those contained in the dividend or other payment
       restrictions prior to such amendment, modification, restatement, renewal,
       increase, supplement, refunding, replacement or refinancing.
 
    LIMITATION ON PREFERRED STOCK OF RESTRICTED SUBSIDIARIES.  The Company will
not permit any of its Restricted Subsidiaries to issue any Preferred Stock
(other than to the Company or to a Restricted Subsidiary of the Company) or
permit any Person (other than the Company or a Restricted Subsidiary of the
Company) to own any Preferred Stock of any Restricted Subsidiary of the Company,
other than Permitted Subsidiary Preferred Stock. The provisions of this covenant
will not apply to any of the Guarantors.
 
    LIMITATION ON LIENS.  The Company will not, and will not cause or permit any
of its Restricted Subsidiaries to, directly or indirectly create, incur, assume
or permit or suffer to exist any Liens of any kind against or upon any property
or assets or any proceeds therefrom, of the Company or any of its Restricted
Subsidiaries whether owned on the Issue Date or acquired after the Issue Date,
in each case to secure Indebtedness or trade payables, unless:
 
        (1) in the case of Liens securing Indebtedness that is expressly
    subordinate or junior in right of payment to the Notes, the Notes are
    secured by a Lien on such property, assets or proceeds that is senior in
    priority to such Liens; and
 
        (2) in all other cases, the Notes are equally and ratably secured,
    except for:
 
           (a) Liens existing as of the Issue Date to the extent and in the
       manner such Liens are in effect on the Issue Date;
 
           (b) Liens securing Senior Debt;
 
           (c) Liens securing the Notes;
 
           (d) Liens of the Company or a Wholly Owned Restricted Subsidiary of
       the Company on assets of any Restricted Subsidiary of the Company;
 
           (e) Liens securing Refinancing Indebtedness which is incurred to
       Refinance any Indebtedness that was secured by a Lien permitted under the
       Indenture and which has been incurred in accordance with the provisions
       of the Indenture; PROVIDED, HOWEVER, that such Liens do not extend to or
       cover any categories of property or assets of the Company or any of its
       Restricted Subsidiaries not securing the Indebtedness so Refinanced; and
 
           (f) Permitted Liens.
 
    PROHIBITION ON INCURRENCE OF SENIOR SUBORDINATED DEBT.  The Company will
not, and will not permit any Restricted Subsidiary that is a Guarantor to, incur
or suffer to exist Indebtedness that is senior in right of payment to the Notes
or such Guarantor's Guarantee, as the case may be, and subordinate in right of
payment to any other Indebtedness of the Company or such Guarantor, as the case
may be.

    MERGER CONSOLIDATION AND SALE OF ASSETS.  The Company will not, in a single
transaction or series of related transactions, consolidate or merge with or into
any Person, or sell, assign, transfer, lease, convey or otherwise dispose of (or

transfer, lease, convey or otherwise dispose of) all or substantially all of the
Company's assets (determined on a consolidated basis for the Company and the
Company's Restricted Subsidiaries) whether as an entirety or substantially as an

        (4) the Company or the Surviving Entity shall have delivered to the
    Trustee an Officers' Certificate and an Opinion of Counsel, each stating
    that such consolidation, merger, sale, assignment, transfer, lease,
    conveyance or other disposition and, if a supplemental indenture is required
    in connection with such transaction, such supplemental indenture comply with
    the applicable provisions of the Indenture and that all conditions precedent
    in the Indenture relating to such transaction have been satisfied.
 
    For purposes of the foregoing, the transfer (by lease, assignment, sale or
otherwise, in a single transaction or series of transactions) of all or
substantially all of the properties or assets of one or more Restricted
Subsidiaries of the Company the Capital Stock of which constitutes all or
substantially all of the properties and assets of the Company, shall be deemed
to be the transfer of all or substantially all of the properties and assets of
the Company. However, transfer of assets between or among the Company and its
Restricted Subsidiaries will not be subject to the foregoing covenant.
 
                                       76
<PAGE>
    The Indenture provides that upon any consolidation, combination or merger or
any transfer of all or substantially all of the assets of the Company in
accordance with the foregoing, in which the Company is not the continuing
corporation, the successor Person formed by such consolidation or into which the
Company is merged or to which such conveyance, lease or transfer is made shall
succeed to, and be substituted for, and may exercise every right and power of,
the Company under the Indenture and the Notes with the same effect as if such
surviving entity had been named as such and that, in the event of a conveyance,
lease or transfer, the conveyor, lessor or transferor will be released from the
provisions of the Indenture.
 
    LIMITATIONS ON TRANSACTIONS WITH AFFILIATES.  The Company will not, and will
not permit any of its Restricted Subsidiaries to, directly or indirectly, enter
into or permit to occur any transaction or series of related transactions
(including, without limitation, the purchase, sale, lease or exchange of any
property or the rendering of any service) with, or for the benefit of, any of
its Affiliates (an "Affiliate Transaction"), other than Affiliate Transactions
on terms that are not materially less favorable than those that might reasonably
have been obtained in a comparable transaction at such time on an arm's-length
basis from a Person that is not an Affiliate of the Company; PROVIDED, HOWEVER,
that for a transaction or series of related transactions with an aggregate value
of $2.5 million or more, at the Company's option, either:
 
        (1) a majority of the disinterested members of the Board of Directors of
    the Company shall determine in good faith that such Affiliate Transaction is
    on terms that are not materially less favorable than those that might
    reasonably have been obtained in a comparable transaction at such time on an
    arm's-length basis from a Person that is not an Affiliate of the Company or
 
        (2) the Board of Directors of the Company or any such Restricted
    Subsidiary party to such Affiliate Transaction shall have received an
    opinion from a nationally recognized investment banking, appraisal or
    accounting firm that such Affiliate Transaction is on terms not materially
    less favorable than those that might reasonably have been obtained in a
    comparable transaction at such time on an arm's-length basis from a Person
    that is not an Affiliate of the Company;
 
and PROVIDED, FURTHER, that for an Affiliate Transaction with an aggregate value
of $10.0 million or more the Board of Directors of the Company or any such
Restricted Subsidiary party to such Affiliate Transaction shall have received an
opinion from a nationally recognized investment banking, appraisal or accounting
firm that such Affiliate Transaction is on terms not materially less favorable
than those that might reasonably have been obtained in a comparable transaction
at such time on an arm's-length basis from a Person that is not an Affiliate of
the Company.
 
    The restrictions set forth in the first paragraph of this covenant shall not
apply to:
 
        (1) reasonable fees and compensation paid to, and indemnity provided on
    behalf of, officers, directors, employees or consultants of the Company or
    any Restricted Subsidiary of the Company as determined in good faith by the
    Company's Board of Directors or senior management;
 
        (2) transactions exclusively between or among the Company and any of its
    Restricted Subsidiaries or exclusively between or among such Restricted
    Subsidiaries, provided such transactions are not otherwise prohibited by the
    Indenture;
 
        (3) any agreement as in effect as of the Issue Date or any amendment
    thereto or any transaction contemplated thereby (including pursuant to any
    amendment thereto) in any replacement agreement thereto so long as any such
    amendment or replacement agreement is not more disadvantageous to the
    Holders in any material respect than the original agreement as in effect on
    the Issue Date;
 
        (4) Restricted Payments or Permitted Investments permitted by the
    Indenture;
 
        (5) transactions effected as part of a Qualified Securitization
    Transaction;
 
                                       77
<PAGE>
        (6) the payment of customary annual management, consulting and advisory
    fees and related expenses to the Permitted Holders and their Affiliates made
    pursuant to any financial advisory, financing, underwriting or placement
    agreement or in respect of other investment banking activities, including,
    without limitation, in connection with acquisitions or divestitures which
    are approved by the Board of Directors of the Company or such Restricted
    Subsidiary in good faith;
 
        (7) payments or loans to employees or consultants that are approved by
    the Board of Directors of the Company in good faith;
 
        (8) sales of Qualified Capital Stock;
 
        (9) the existence of, or the performance by the Company or any of its
    Restricted Subsidiaries of its obligations under the terms of, any
    stockholders agreement (including any registration rights agreement or
    purchase agreement related thereto) to which it is a party as of the Issue
    Date and any similar agreements which it may enter into thereafter;
    PROVIDED, HOWEVER, that the existence of, or the performance by the Company
    or any of its Restricted Subsidiaries of obligations under, any future
    amendment to any such existing agreement or under any similar agreement
    entered into after the Issue Date shall only be permitted by this clause (9)
    to the extent that the terms of any such amendment or new agreement are not
    disadvantageous to the Holders of the Notes in any material respect; and
 
        (10) transactions permitted by and complying with, the provisions of the
    "Merger, Consolidation and Sale of Assets" covenant.
 
    FUTURE GUARANTEES BY RESTRICTED SUBSIDIARIES.  The Company will not create
or acquire another Domestic Restricted Subsidiary unless such Domestic
Restricted Subsidiary executes and delivers a supplemental indenture to the
Indenture, providing for a senior subordinated guarantee of payment of the Notes
by such Restricted Subsidiary (the "Guarantee").
 
    Notwithstanding the foregoing, any such Guarantee by a Domestic Restricted
Subsidiary of the Notes shall provide by its terms that it shall be
automatically and unconditionally released and discharged, without any further
action required on the part of the Trustee or any Holder, upon any sale or other
disposition (by merger or otherwise) to any Person which is not a Restricted
Subsidiary of the Company of all of the Company's Capital Stock in, or all or
substantially all of the assets of, such Domestic Restricted Subsidiary;
PROVIDED that such sale or disposition of such Capital Stock or assets is
otherwise in compliance with the terms of the Indenture. A form of such
Guarantee will be attached as an exhibit to the Indenture.
 
    CONDUCT OF BUSINESS.  The Indenture provides that the Company will not, and
will not permit any of its Restricted Subsidiaries to, engage in any businesses
a majority of whose revenues are not derived from businesses that are the same
or reasonably similar, ancillary or related to, or a reasonable extension,
development or expansion of, the businesses in which the Company and its
Restricted Subsidiaries are engaged on the Issue Date.
 
    REPORTS TO HOLDERS.  The Indenture provides that, whether or not required by
the rules and regulations of the Commission, so long as any Notes are
outstanding, the Company will furnish to the Holders of Notes:
 
        (1) all quarterly and annual financial information that would be
    required to be contained in a filing with the Commission on Forms 10-Q and
    10-K if the Company were required to file such Forms, including a
    "Management's Discussion and Analysis of Financial Condition and Results of
    Operations" that describes the financial condition and results of operations
    of the Company and its consolidated Subsidiaries (showing in reasonable
    detail, either on the face of the financial statements or in the footnotes
    thereto and in Management's Discussion and Analysis of Financial Condition
    and Results of Operations, the financial condition and results of operations
    of the
 
                                       78
<PAGE>
    Company and its Restricted Subsidiaries separate from the financial
    condition and results of operations of the Unrestricted Subsidiaries of the
    Company) and, with respect to the annual information only, a report thereon
    by the Company's certified independent accountants and
 
        (2) all current reports that would be required to be filed with the
    Commission on Form 8-K if the Company were required to file such reports, in
    each case, within the time periods specified in the Commission's rules and
    regulations. For so long as Holdings is a guarantor of the Notes, the
    Indenture permits the Company to satisfy its obligations under this covenant
    by furnishing financial information relating to Holdings; PROVIDED that the
    same is accompanied by consolidating information that explains in reasonable
    detail the differences between the information relating to Holdings, on the
    one hand, and the information relating to the Company and its Restricted
    Subsidiaries on a stand-alone basis, on the other hand.
 
    In addition, following the consummation of the exchange offer contemplated
by the Registration Rights Agreement, whether or not required by the rules and
regulations of the Commission, the Company will file a copy of all such
information and reports with the Commission for public availability within the
time periods specified in the Commission's rules and regulations (unless the
Commission will not accept such a filing) and make such information available to
securities analysts and prospective investors upon request. In addition, the
Company has agreed that, for so long as any Notes remain outstanding, it will
furnish to the Holders and to securities analysts and prospective investors,
upon their request, the information required to be delivered pursuant to Rule
144A(d) (4) under the Securities Act.
 
EVENTS OF DEFAULT
 
    The following events are defined in the Indenture as "Events of Default":
 
        (1) the failure to pay interest on any Notes when the same becomes due
    and payable and the default continues for a period of 30 days (whether or
    not such payment shall be prohibited by the subordination provisions of the
    Indenture);
 
        (2) the failure to pay the principal on any Notes, when such principal
    becomes due and payable, at maturity, upon redemption or otherwise
    (including the failure to make a payment to purchase Notes tendered pursuant
    to a Change of Control Offer or a Net Proceeds Offer on the date specified
    for such payment in the applicable offer to purchase) (whether or not such
    payment shall be prohibited by the subordination provisions of the
    Indenture);
 
        (3) a default in the observance or performance of any other covenant or
    agreement contained in the Indenture which default continues for a period of
    30 days after the Company receives written notice specifying the default
    (and demanding that such default be remedied) from the Trustee or the
    Holders of at least 25% of the outstanding principal amount of the Notes
    (except in the case of a default with respect to the "Merger, Consolidation
    and Sale of Assets" covenant, which will constitute an Event of Default with
    such notice requirement but without such passage of time requirement);
 
        (4) the failure to pay at final stated maturity (giving effect to any
    applicable grace periods and any extensions thereof) the principal amount of
    any Indebtedness of the Company or any Restricted Subsidiary of the Company
    (other than a Securitization Entity) which failure continues for at least 20
    days, or the acceleration of the final stated maturity of any such
    Indebtedness, which acceleration remains uncured or unrescinded for at least
    20 days, if the aggregate principal amount of such Indebtedness, together
    with the principal amount of any other such Indebtedness in default for
    failure to pay principal at final maturity or which has been accelerated (in
    each case with respect to which the 20-day period described above has
    passed), aggregates $5.0 million or more at any time;
 
                                       79
<PAGE>
        (5) one or more judgments in an aggregate amount in excess of $5.0
    million shall have been rendered against the Company or any of its
    Significant Subsidiaries and such judgments remain undischarged, unpaid or
    unstayed for a period of 60 days after such judgment or judgments become
    final and non-appealable; or
 
        (6) certain events of bankruptcy affecting the Company or any of its
    Significant Subsidiaries.
 
    If an Event of Default (other than an Event of Default specified in clause
(6) above with respect to the Company) shall occur and be continuing, the
Trustee or the Holders of at least 25% in principal amount of outstanding Notes
may declare the principal of and accrued interest on all the Notes to be due and
payable by notice in writing to the Company and the Trustee specifying the
respective Event of Default and that it is a "notice of acceleration" (the
"Acceleration Notice"), and the same:
 
        (1) shall become immediately due and payable or
 
        (2) if there are any amounts outstanding under the New Credit Facility,
    shall become immediately due and payable upon the first to occur of an
    acceleration under the New Credit Facility or 5 business days after receipt
    by the Company and the Representative under the New Credit Facility of such
    Acceleration Notice but only if such Event of Default is then continuing. If
    an Event of Default specified in clause (6) above with respect to the
    Company occurs and is continuing, then all unpaid principal of, and premium,
    if any, and accrued and unpaid interest on all of the outstanding Notes
    shall IPSO FACTO become and be immediately due and payable without any
    declaration or other act on the part of the Trustee or any Holder.
 
    The Indenture provides that, at any time after a declaration of acceleration
with respect to the Notes as described in the preceding paragraph, the Holders
of a majority in principal amount of the Notes may rescind and cancel such
declaration and its consequences:
 
        (1) if the rescission would not conflict with any judgment or decree;
 
        (2) if all existing Events of Default have been cured or waived except
    nonpayment of principal or interest that has become due solely because of
    the acceleration;
 
        (3) to the extent the payment of such interest is lawful, interest on
    overdue installments of interest and overdue principal, which has become due
    otherwise than by such declaration of acceleration, has been paid;
 
        (4) if the Company has paid the Trustee its reasonable compensation and
    reimbursed the Trustee for its expenses, disbursements and advances; and
 
        (5) in the event of the cure or waiver of an Event of Default of the
    type described in clause (6) of the description above of Events of Default,
    the Trustee shall have received an officers' certificate and an opinion of
    counsel that such Event of Default has been cured or waived. No such
    rescission shall affect any subsequent Default or impair any right
    consequent thereto.
 
    The Holders of a majority in principal amount of the Notes may waive any
existing Default or Event of Default under the Indenture, and its consequences,
except a default in the payment of the principal of or interest on any Notes.
 
    Holders of the Notes may not enforce the Indenture or the Notes except as
provided in the Indenture and under the TIA. Subject to the provisions of the
Indenture relating to the duties of the Trustee, the Trustee is under no
obligation to exercise any of its rights or powers under the Indenture at the
request, order or direction of any of the Holders, unless such Holders have
offered to the Trustee reasonable indemnity. Subject to all provisions of the
Indenture and applicable law, the Holders of a majority in aggregate principal
amount of the then outstanding Notes have the right to direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee
or exercising any trust or power conferred on the Trustee.
 
                                       80
<PAGE>
    Under the Indenture, the Company is required to provide an officers'
certificate to the Trustee promptly upon any such officer obtaining knowledge of
any Default or Event of Default (provided that such officers shall provide such
certification at least annually whether or not they know of any Default or Event
of Default) that has occurred and, if applicable, describe such Default or Event
of Default and the status thereof.
 
LEGAL DEFEASANCE AND COVENANT DEFEASANCE
 
    The Company may, at its option and at any time, elect to have its
obligations discharged with respect to the outstanding Notes ("Legal
Defeasance"). Such Legal Defeasance means that the Company shall be deemed to
have paid and discharged the entire indebtedness represented by the outstanding
Notes, except for:
 
        (1) the rights of Holders to receive payments in respect of the
    principal of, premium, if any, and interest on the Notes when such payments
    are due;
 
        (2) the Company's obligations with respect to the Notes concerning
    issuing temporary Notes, registration of Notes, mutilated, destroyed, lost
    or stolen Notes and the maintenance of an office or agency for payments;
 
        (3) the rights, powers, trust, duties and immunities of the Trustee and
    the Company's obligations in connection therewith; and
 
        (4) the Legal Defeasance provisions of the Indenture.
 
    In addition, the Company may, at its option and at any time, elect to have
the obligations of the Company released with respect to certain covenants that
are described in the Indenture ("Covenant Defeasance") and thereafter any
omission to comply with such obligations shall not constitute a Default or Event
of Default with respect to the Notes. In the event Covenant Defeasance occurs,
certain events (not including non-payment, bankruptcy, receivership,
reorganization and insolvency events) described under "Events of Default" will
no longer constitute an Event of Default with respect to the Notes.
 
    In order to exercise either Legal Defeasance or Covenant Defeasance:
 
        (1) the Company must irrevocably deposit with the Trustee, in trust, for
    the benefit of the Holders cash in U.S. dollars, non-callable U.S.
    government obligations, or a combination thereof, in such amounts as will be
    sufficient, in the opinion of a nationally recognized firm of independent
    public accountants, to pay the principal of, premium, if any, and interest
    on the Notes on the stated date for payment thereof or on the applicable
    redemption date, as the case may be;
 
        (2) in the case of Legal Defeasance, the Company shall have delivered to
    the Trustee an opinion of counsel in the United States reasonably acceptable
    to the Trustee confirming that
 
           (a) the Company has received from, or there has been published by the
       Internal Revenue Service a ruling or
 
           (b) since the date of the Indenture, there has been a change in the
       applicable federal income tax law,
 
    in either case to the effect that, and based thereon such opinion of counsel
    shall confirm that, the Holders will not recognize income, gain or loss for
    federal income tax purposes as a result of such Legal Defeasance and will be
    subject to federal income tax on the same amounts, in the same manner and at
    the same times as would have been the case if such Legal Defeasance had not
    occurred;
 
        (3) in the case of Covenant Defeasance, the Company shall have delivered
    to the Trustee an opinion of counsel in the United States reasonably
    acceptable to the Trustee confirming that the
 
                                       81
<PAGE>
    Holders will not recognize income, gain or loss for federal income tax
    purposes as a result of such Covenant Defeasance and will be subject to
    federal income tax on the same amounts, in the same manner and at the same
    times as would have been the case if such Covenant Defeasance had not
    occurred;
 
        (4) no Default or Event of Default shall have occurred and be continuing
    on the date of such deposit (other than a Default or an Event of Default
    resulting from the borrowing of funds to be applied to such deposit and the
    grant of any Lien securing such borrowing) or insofar as Events of Default
    from bankruptcy or insolvency events are concerned, at any time in the
    period ending on the 91st day after the date of deposit;
 
        (5) such Legal Defeasance or Covenant Defeasance shall not result in a
    breach or violation of, or constitute a default under the Indenture (other
    than a Default or an Event of Default resulting from the borrowing of funds
    to be applied to such deposit and the grant of any Lien securing such
    borrowing) or any other material agreement or instrument to which the
    Company or any of its Subsidiaries is a party or by which the Company or any
    of its Subsidiaries is bound;
 
        (6) the Company shall have delivered to the Trustee an officers'
    certificate stating that the deposit was not made by the Company with the
    intent of preferring the Holders over any other creditors of the Company or
    with the intent of defeating, hindering, delaying or defrauding any other
    creditors of the Company or others;
 
        (7) the Company shall have delivered to the Trustee an officers'
    certificate and an opinion of counsel, each stating that all conditions
    precedent provided for or relating to the Legal Defeasance or the Covenant
    Defeasance have been complied with;
 
        (8) the Company shall have delivered to the Trustee an opinion of
    counsel to the effect that:
 
           (a) the trust funds will not be subject to any rights of holders of
       Senior Debt, including, without limitation, those arising under the
       Indenture; and
 
           (b) after the 91st day following the deposit, the trust funds will
       not be subject to the effect of any applicable bankruptcy, insolvency,
       reorganization or similar laws affecting creditors' rights generally; and
 
        (9) certain other customary conditions precedent are satisfied.
 
    Notwithstanding the foregoing, the opinion of counsel required by clause (2)
above with respect to a Legal Defeasance need not be delivered if all Notes not
therefore delivered to the Trustee for cancellation (1) have become due and
payable, or (2) will become due and payable on the maturity date within one year
under arrangements satisfactory to the Trustee for the giving of notice of
redemption by the Trustee in the name, and at the expense, of the Company.
 
SATISFACTION AND DISCHARGE
 
    The Indenture will be discharged and will cease to be of further effect
(except as to surviving rights or registration of transfer or exchange of the
Notes, as expressly provided for in the Indenture) as to all outstanding Notes
when
 
        (1) either:
 
           (a) all the Notes theretofore authenticated and delivered (except
       lost, stolen or destroyed Notes which have been replaced or paid and
       Notes for whose payment money has theretofore been deposited in trust or
       segregated and held in trust by the Company and thereafter repaid to the
       Company or discharged from such trust) have been delivered to the Trustee
       for cancellation or
 
                                       82
<PAGE>
           (b) all Notes not theretofore delivered to the Trustee for
       cancellation have become due and payable, pursuant to an optional
       redemption notice or otherwise, and the Company has irrevocably deposited
       or caused to be deposited with the Trustee funds in an amount sufficient
       to pay and discharge the entire Indebtedness on the Notes not theretofore
       delivered to the Trustee for cancellation, for principal of, premium, if
       any, and interest on the Notes to the date of deposit together with
       irrevocable instructions from the Company directing the Trustee to apply
       such funds to the payment thereof at maturity or redemption, as the case
       may be; and
 
        (2) the Company has paid all other sums payable under the Indenture by
    the Company,
 
    The Trustee will acknowledge the satisfaction and discharge of the Indenture
if the Company has delivered to the Trustee an officers' certificate and an
opinion of counsel stating that all conditions precedent under the Indenture
relating to the satisfaction and discharge of the Indenture have been complied
with.
 
MODIFICATION OF THE INDENTURE
 
    From time to time, the Company and the Trustee, without the consent of the
Holders, may amend the Indenture for certain specified purposes, including
curing ambiguities, defects or inconsistencies, so long as such change does not,
in the opinion of the Trustee, adversely affect the rights of any of the Holders
in any material respect. In formulating its opinion on such matters, the Trustee
will be entitled to rely on such evidence as it deems appropriate, including,
without limitation, solely on an opinion of counsel. Other modifications and
amendments of the Indenture may be made with the consent of the Holders of a
majority in principal amount of the then outstanding Notes issued under the
Indenture, except that, without the consent of each Holder affected thereby, no
amendment may:
 
        (1) reduce the amount of Notes whose Holders must consent to an
    amendment;
 
        (2) reduce the rate of or change or have the effect of changing the time
    for payment of interest, including defaulted interest, on any Notes;
 
        (3) reduce the principal of or change or have the effect of changing the
    fixed maturity of any Notes, or change the date on which any Notes may be
    subject to redemption or reduce the redemption price therefor;
 
        (4) make any Notes payable in money other than that stated in the Notes;
 
        (5) make any change in the provisions of the Indenture protecting the
    right of each Holder to receive payment of principal of and interest on such
    Note on or after the due date thereof or to bring suit to enforce such
    payment, or permitting Holders of a majority in principal amount of Notes to
    waive Defaults or Events of Default;
 
        (6) after the Company's obligation to purchase Notes arises thereunder,
    amend, change or modify in any material respect the obligation of the
    Company to make and consummate a Change of Control Offer in the event of a
    Change of Control or modify any of the provisions or definitions with
    respect thereto after a Change of Control has occurred; or
 
        (7) modify or change any provision of the Indenture or the related
    definitions affecting the subordination or ranking of the Notes in a manner
    which adversely affects the Holders.
 
GOVERNING LAW
 
    The Indenture provides that it and the Notes will be governed by, and
construed in accordance with, the laws of the State of New York but without
giving effect to applicable principles of conflicts of law to the extent that
the application of the law of another jurisdiction would be required thereby.
 
                                       83
<PAGE>
THE TRUSTEE
 
    The Indenture provides that, except during the continuance of an Event of
Default, the Trustee will perform only such duties as are specifically set forth
in the Indenture. During the existence of an Event of Default, the Trustee will
exercise such rights and powers vested in it by the Indenture, and use the same
degree of care and skill in its exercise as a prudent man would exercise or use
under the circumstances in the conduct of his own affairs.
 
    The Indenture and the provisions of the TIA contain certain limitations on
the rights of the Trustee, should it become a creditor of the Company, to obtain
payments of claims in certain cases or to realize on certain property received
in respect of any such claim as security or otherwise. Subject to the TIA, the
Trustee will be permitted to engage in other transactions; provided that if the
Trustee acquires any conflicting interest as described in the TIA, it must
eliminate such conflict or resign.
 
CERTAIN DEFINITIONS
 
    Set forth below is a summary of certain of the defined terms used in the
Indenture. Reference is made to the Indenture for the full definition of all

           (vii) Indebtedness which, when incurred and without respect to any
       election under Section 1111(b) of Title 11, United States Code, is

                              REGISTRATION RIGHTS
 
    THE SUMMARY SET FORTH BELOW OF CERTAIN PROVISIONS OF THE REGISTRATION RIGHTS
AGREEMENT DOES NOT PURPORT TO BE COMPLETE AND IS SUBJECT TO, AND IS QUALIFIED IN
ITS ENTIRETY BY, ALL THE PROVISIONS OF THE REGISTRATION RIGHTS AGREEMENT, A COPY
OF WHICH HAS BEEN FILED AS AN EXHIBIT TO THE REGISTRATION STATEMENT.
 
    The Company, the Guarantors and the Initial Purchasers entered into the
Registration Rights Agreement on December 3, 1998 (the "Issue Date") pursuant to
which each of the Company and the Guarantors agreed that they will, at their
expense, for the benefit of holders of the Old Notes (the "Holders"), (i) within
60 days after the Issue Date (the "Filing Date"), file a registration statement
on an appropriate registration form (the "Exchange Offer Registration
Statement") with respect to a registered offer (the "Exchange Offer") to
exchange the Old Notes for these New Notes, guaranteed on a senior subordinated
basis by the Guarantors, which New Notes will have terms substantially identical
in all material respects to the Old Notes (except that the New Notes will not
contain terms with respect to transfer restrictions) and (ii) cause the Exchange
Offer Registration Statement to be declared effective under the Securities Act
within 150 days after the Issue Date. Upon the Exchange Offer Registration
Statement being declared effective, the Company will offer these New Notes (and
related securities) in exchange for surrender of the Old Notes. The Company will
keep the Exchange Offer open for not less than 30 days (or longer if required by
applicable law) after the date notice of the Exchange Offer is mailed to the
Holders. For each of the Old Notes surrendered to the Company pursuant to the
Exchange Offer, the Holder who surrendered such Old Note will receive an New
Note having a principal amount equal to that of the surrendered Old Note.
Interest on each New Note will accrue (A) from the later of (i) the last
interest payment date on which interest was paid on the Old Note surrendered in
exchange therefor, or (ii) if the Old Note is surrendered for exchange on a date
in a period which includes the record date for an interest payment date to occur
on or after the date of such exchange and as to which interest will be paid, the
date of such interest payment date or (B) if no interest has been paid on such
Old Note, from the Issue Date.
 
    Based on an interpretation by the Commission's staff set forth in no-action
letters issued to third parties unrelated to the Company, the Company believes
that, with the exceptions set forth below, New Notes issued pursuant to the
exchange offer in exchange for Old Notes may be offered for resale, resold and
otherwise transferred by holders thereof (other than any holder which is an
"affiliate" of the Company within the meaning of Rule 405 promulgated under the
Securities Act, or a broker-dealer who purchased Old Notes directly from the
Company to resell pursuant to Rule 144A or any other available exemption
promulgated under the Securities Act) without compliance with the registration
and prospectus delivery provisions of the Securities Act, provided that the New
Notes are acquired in the ordinary course of business of the holder and the
holder does not have an arrangement or understanding with any person to
participate in the distribution of such New Notes. Any holder who tenders in the
exchange offer for the purpose of participating in a distribution of the New
Notes cannot rely on this interpretation by the Commission's staff and must
comply with the registration and prospectus delivery requirements of the
Securities Act in connection with a secondary resale transaction. Each
broker-dealer that receives New Notes for its own account in exchange for Old
Notes, where such Old Notes were acquired by such broker-dealer as a result of
market-making activities or other trading activities, must acknowledge that it
will deliver a prospectus in connection with any resale of such New Notes. See
"Plan of Distribution." Broker-dealers who acquired Old Notes directly from us
and not as a result of market-making activities or other trading activities may
not rely on the staff's interpretations discussed above or participate in the
exchange offer and must comply with the prospectus delivery requirements of the
Securities Act in order to sell the Old Notes.
 
    If, (i) because of any change in law or in currently prevailing
interpretations of the Staff of the Commission, the Company is not permitted to
effect an exchange offer, (ii) the exchange offer is not consummated within 185
days of the Issue Date or (iii) in certain circumstances, certain holders of
unregistered Old Notes so request, or (iv) in the case of any Holder that
participates in the exchange
 
                                      104
<PAGE>
offer, such Holder does not receive New Notes on the date of the exchange that
may be sold without restriction under state and federal securities laws (other
than due solely to the status of such Holder as an affiliate of the Company
within the meaning of the Securities Act), then in each case, the Company will
(x) promptly deliver to the Holders and the Trustee written notice thereof and
(y) at its sole expense, (a) as promptly as practicable, file a shelf
registration statement covering resales of the Old Notes (the "Shelf
Registration Statement"); and (b) use their best efforts to keep effective the
Shelf Registration Statement until the earlier of two years after its effective
date or such time as all of the applicable Old Notes have been sold thereunder.
The Company will, in the event that a Shelf Registration Statement is filed,
provide to each Holder copies of the prospectus that is a part of the Shelf
Registration Statement, notify each such Holder when the Shelf Registration
Statement for the Old Notes has become effective and take certain other actions
as are required to permit unrestricted resales of the Old Notes. A Holder that
sells Old Notes pursuant to the Shelf Registration Statement will be required to
be named as a selling security holder in the related prospectus and to deliver a
prospectus to purchasers, 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 Rights Agreement that are applicable
to such a Holder (including certain indemnification rights and obligations).
 
    If the Company fails to comply with the above provisions or if the Exchange
Offer Registration Statement or the Shelf Registration Statement fails to become
effective, then, as liquidated damages, additional interest (the "Additional
Interest") shall become payable in respect of the Old Notes as follows:
 
        (i) if (A) neither the Exchange Offer Registration Statement or Shelf
    Registration Statement is filed with the Commission on or prior to the
    applicable filing date or (B) notwithstanding that the Company has
    consummated or will consummate an exchange offer, the Company is required to
    file a Shelf Registration Statement and such Shelf Registration Statement is
    not filed on or prior to the date required by the Registration Rights
    Agreement, then commencing on the day after either such required filing
    date, Additional Interest shall accrue on the principal amount of the Old
    Notes at a rate of 0.50% per annum for the first 90 days immediately
    following each such filing date, such Additional Interest rate increasing by
    an additional 0.50% per annum at the beginning of each subsequent 90-day
    period; or
 
        (ii) if (A) neither the Exchange Offer Registration Statement nor a
    Shelf Registration Statement is declared effective by the Commission on or
    prior to 90 days after the applicable filing deadline set for such filing in
    the Registration Rights Agreement or (B) notwithstanding that the Company
    has consummated or will consummate an exchange offer, the Company is
    required to file a Shelf Registration Statement and such Shelf Registration
    Statement is not declared effective by the Commission on or prior to the
    90th day following the filing date deadline set for such filing in the
    Registration Rights Agreement, then, commencing on the day after such 90th
    day following the filing deadline set for such filing in the Registration
    Rights Agreement, Additional Interest shall accrue on the principal amount
    of the Old Notes at a rate of 0.50% per annum for the first 90 days
    immediately following such date, such Additional Interest rate increasing by
    an additional 0.50% per annum at the beginning of each subsequent 90-day
    period; or
 
       (iii) if (A) the Company has not exchanged New Notes for all Old Notes
    validly tendered in accordance with the terms of the exchange offer on or
    prior to the 185th day after the Issue Date or (B) if applicable, the Shelf
    Registration Statement ceases to be effective at any time prior to the
    second anniversary of the Issue Date (other than after such time as all Old
    Notes have been disposed of thereunder), then Additional Interest shall
    accrue on the principal amount of the Old Notes at a rate of 0.50% per annum
    for the first 90 days commencing on (x) the 185th day after the Issue Date,
    in the case of (A) above, or (y) the day such Shelf Registration Statement
    ceases
 
                                      105
<PAGE>
    to be effective in the case of (B) above, such Additional Interest rate
    increasing by an additional 0.50% per annum at the beginning of each
    subsequent 90-day period;
 
PROVIDED, HOWEVER, that the Additional Interest rate on the Old Notes may not
accrue under more than one of the foregoing clauses (i)-(iii) at any one time
and at no time shall the aggregate amount of Additional Interest accruing exceed
in the aggregate 1.0% per annum; PROVIDED, FURTHER, HOWEVER, that (1) upon the
filing of the Exchange Offer Registration Statement or a Shelf Registration
Statement (in the case of clause (i) above), (2) upon the effectiveness of the
Exchange Offer Registration Statement or a Shelf Registration Statement (in the
case of clause (ii) above), or (3) upon the exchange of New Notes for all Old
Notes tendered (in the case of clause (iii)(A) above), or upon the effectiveness
of the Shelf Registration Statement which had ceased to remain effective (in the
case of clause (iii)(B) above), Additional Interest on the Old Notes as a result
of such clause (or the relevant subclause thereof), as the case may be, shall
cease to accrue.
 
    Any amounts of Additional Interest due pursuant to clause (i), (ii) or (iii)
above will be payable in cash on the original interest payment dates for the Old
Notes.

                         BOOK-ENTRY; DELIVERY AND FORM
 
    The certificates representing the New Notes will be issued in fully
registered form without interest coupons.
 
    Except as described herein under the heading "-Certificated Securities," New
Notes will initially be represented by a permanent global New Note in fully
registered form without interest coupons (the "Global Note") and will be
deposited with the Trustee as custodian for The Depositary Trust Company ("DTC")
and registered in the name of a nominee of such depositary.
 
THE GLOBAL NOTE
 
    The Company expects that pursuant to procedures established by DTC (i) upon
the issuance of the Global Note, DTC or its custodian will credit, on its
internal system, the principal amount of the individual beneficial interests
represented by the Global Note to the respective accounts of persons who have
accounts with such depositary and (ii) ownership of beneficial interests in the
Global Note will be shown on, and the transfer of such ownership will be
effected only through, records maintained by DTC or its nominee (with respect to
interests of participants) and the records of participants (with respect to
interests of persons other than participants). Ownership of beneficial interests
in the Global Notes will be limited to persons who have accounts with DTC
("participants") or persons who hold interests through participants.
 
    So long as DTC, or its nominee, is the registered owner or holder of the New
Notes, DTC or such nominee, as the case may be, will be considered the sole
owner or holder of the New Notes represented by the Global Note for all purposes
under the Indenture. No beneficial owner of an interest in the Global Note will
be able to transfer that interest except in accordance with DTC's procedures, in
addition to those provided for under the Indenture.
 
    Payments of the principal of, premium (if any), and interest on, the Global
Note will be made to DTC or its nominee, as the case may be, as the registered
owner thereof. None of the Company, the Trustee or any paying agent will have
any responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in the Global Note or
for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.
 
    The Company expects that DTC or its nominee, upon receipt of any payment of
principal, premium, if any, or interest on the Global Note, will credit
participants' accounts with payments in amounts proportionate to their
respective beneficial interests in the principal amount of the Global Note as
shown on the records of DTC or its nominee. The Company also expects that
payments by participants to owners of beneficial interests in the Global Note
held through such participants will be governed by standing instructions and
customary practice, as is now the case with securities held for the accounts of
customers registered in the names of nominees for such customers. Such payments
will be the responsibility of such participants.
 
    Transfers between participants in DTC will be effected in the ordinary way
through DTC's same-day funds system in accordance with DTC rules and will be
settled in same-day funds. If a holder requires physical delivery of a
Certificated Security for any reason, including to sell New Notes to persons in
states that require physical delivery of the New Notes, or to pledge such
securities, such holder must transfer its interest in the Global Note, in
accordance with the normal procedures of DTC and with the procedures set forth
in the Indenture.
 
    DTC has advised the Company that it will take any action permitted to be
taken by a holder of New Notes (including the presentation of New Notes for
exchange as described below) only at the direction of one or more participants
to whose accounts the DTC interests in the Global Note are credited and only in
respect of such portion of the aggregate principal amount of New Notes as to
which such participant or participants has or have given such direction.
However, if there is an Event
 
                                      107
<PAGE>
of Default under the Indenture applicable to the Global Note, DTC will exchange
the Global Note for Certificated Securities, which it will distribute to its
participants.
 
    Although DTC has agreed to the foregoing procedures in order to facilitate
transfers of interests in the Global Note among participants of DTC, it is under
no obligation to perform such procedures and such procedures may be discontinued
at any time. Neither the Company nor the Trustee will have any responsibility
for the performance by DTC or its participants or indirect participants of their
respective obligations under the rules and procedures governing their
operations.
 
CERTIFICATED SECURITIES
 
    Certificated securities shall be issued in exchange for the Old Notes in the
exchange offer or for beneficial interest in the Global Note, in each case, if
requested by a holder of such Old Note or such beneficial interests,
respectively. In addition, certificated securities shall be issued in exchange
for beneficial interests in the Global Note if DTC is at any time unwilling or
unable to continue as a depositary for the Global Note and a successor
depositary is not appointed by the Company within 90 days.

            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS
 
    The following general discussion summarizes certain of the material U.S.
federal income tax aspects of the exchange offer to holders of the Old Notes.
This discussion is summary for general information only and does not consider
all aspects of the Old Notes in light of such holder's personal circumstances.
This discussion also does not address the U.S. federal income tax consequences
to holders subject to special treatment under the U.S. federal income tax laws,
such as dealers in securities, or foreign currency, tax-exempt entities, banks,
thrifts, insurance companies, persons that hold the Old Notes as part of a
"straddle", a "hedge" against currency risk or a "conversion transaction";
persons that have a "functional currency" other than the U.S. dollar, and
investors in pass-through entities. In addition, this discussion does not
prescribe any tax consequences arising out of the tax laws of any state, local
or foreign jurisdiction.
 
    This discussion is based upon the Code, existing and presupposed regulations
thereunder, Internal Revenue Service ("IRS") rulings and pronouncements and
judicial decision now in effect, all of which are subject to change (possibly on
a retroactive basis). The Company has not and will not seek any rulings or
opinions from the IRS or counsel with respect to the matters discussed below.
There can be no assurance that the IRS will not take positions concerning the
tax consequences of the exchange offer which are difference from those discussed
herein.
 
    HOLDERS OF THE OLD NOTES SHOULD CONSULT THEIR OWN ADVISORS CONCERNING THE
APPLICATION OF U.S. FEDERAL INCOME TAX LAWS, AS WELL AS THE LAWS OF ANY STATE,
LOCAL OR FOREIGN JURISDICTION, TO THE EXCHANGE OFFER IN LIGHT OF THEIR
PARTICULAR SITUATIONS.
 
    The exchange of Old Notes for New Notes pursuant to the exchange offer
should not constitute a taxable exchange. As a result, a holder (i) should not
recognize taxable gains of loss as a result of exchanging Old Notes for New
Notes pursuant to the exchange offer, (ii) the holding period of the New Notes
should include the holding period of the Old Notes exchanged therefor and (iii)
the adjusted tax basis of the New Notes should be the same as the adjusted tax
basis of the Old Notes exchange therefore immediately before the exchange.

                              PLAN OF DISTRIBUTION
 
    Each broker-dealer that receives New Notes for its own account pursuant to
the exchange offer must acknowledge that it will deliver 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 by a broker-dealer in
connection with the resales of New Notes received in exchange for Old Notes
where such Old Notes were acquired as a result of market-making activities or
other trading activities. The Company has agreed that for a period of up to 180
days after the Expiration Date, it will make this Prospectus, as amended or
supplemented, available to any broker-dealer that requests such document in the
letter of transmittal for use in connection with any such resale.
 
    The Company and the Guarantors will not receive any proceeds from any sale
of New Notes by broker-dealers or any other persons. New Notes received by
broker-dealers for their own account pursuant to the exchange offer may be sold
from time to time in one or more transactions in the over-the-counter market, in
negotiated transactions, through the writing of options on the New Notes or a
combination of such methods of resale, at market prices prevailing at the time
of resale, at prices related to such prevailing market prices or negotiated
prices. Any such resale may be made directly to purchasers or to or through
brokers or dealers who may receive compensation in the form of commissions or
concessions from any such broker-dealer 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 broker or dealer that
participates in a distribution of such New Notes may be deemed to be an
"underwriter" within the meaning of the Securities Act and any profit on any
such resale of New Notes and any 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 that it will deliver 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.
 
    The Company has agreed to pay all expenses incident to the Company's
performance of, or compliance with, the Registration Rights Agreement and will
indemnify the holders of Old Notes (including any broker-dealers), and certain
parties related to such holders, against certain liabilities, including
liabilities under the Securities Act.

INDEPENDENT AUDITORS' REPORT
 
To the Shareholders and Board of Directors of
TransDigm Holding Company
 
    We have audited the accompanying consolidated balance sheets of TransDigm
Holding Company and its subsidiaries (the "Company") as of September 30, 1998
and 1997, and the related consolidated statements of income and retained
earnings (deficit) and of cash flows for each of the three years in the period
ended September 30, 1998. 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 audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of TransDigm Holding Company and
its subsidiaries as of September 30, 1998 and 1997, and the results of their
operations and their cash flows for each of the three years in the period ended
September 30, 1998 in conformity with generally accepted accounting principles.
 
    As discussed in Note 17 to the consolidated financial statements, in 1998,
the Company retroactively changed its method of accounting for put warrants.

                           TRANSDIGM HOLDING COMPANY
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                 YEARS ENDED SEPTEMBER 30, 1998, 1997 AND 1996
 
1. DESCRIPTION OF THE BUSINESS AND MERGER
 
    TransDigm Holding Company ("Holding") through its wholly-owned operating
subsidiary, TransDigm Inc. ("TransDigm"), is a premier supplier of proprietary
mechanical components servicing the aircraft, mining, marine and other
manufacturing industries. TransDigm along with its wholly-owned subsidiary,
Marathon Power Technologies Company ("Marathon"), offers a broad line of
component products including tube connectors, valves, batteries, static
inverters, pumps, quick disconnects, clamps and ball bearing and sliding
controls. Holding has no operations, liabilities or assets except for its
investment in TransDigm.
 
    On August 3, 1998, Phase II Acquisition Corp. ("Acquiror"), an entity formed
by affiliates of Odyssey Investment Partners, LP ("Odyssey") and Holding entered
into a definitive agreement and plan of merger which agreement was amended on
November 9, 1998 (the "Merger Agreement" or the "Merger"). Pursuant to the terms
of the Merger, Acquiror will be merged with and into Holding, with Holding being
the surviving corporation in the Merger (the "Surviving Corporation"). In the
Merger, holders of Holding's outstanding common stock will be entitled to
receive, in exchange for each outstanding share of common stock (except for
shares held directly or indirectly by Holding or the Rolled Shares, as defined
below) the "Per Share Merger Consideration" as defined in the Merger Agreement.
The aggregate consideration payable pursuant to the Merger, including amounts
payable to holders of options and warrants, is expected to be approximately
$299.7 million.
 
    In connection with the Merger, Kelso Investment Associates IV, LP and Kelso
Equity Partners II, L.P. (collectively "Kelso") will retain approximately 15.4%
of the Surviving Corporation's outstanding common stock (the "Rolled Shares")
subject to adjustment for certain transactions prior to closing. In addition,
certain members of management of Holding agreed, in connection with and as a
condition to entering into the Merger Agreement, to rollover stock options with
an estimated gross and net value of approximately $17.2 million and $13.7
million, respectively.
 
    The Merger is intended to be treated as a recapitalization for financial
reporting purposes which will have no impact on the historical basis of
Holding's consolidated assets and liabilities. The Merger is subject to
customary closing conditions, including the termination or expiration of the
relevant waiting period under the Hart-Scott-Rodino Antitrust Improvement Act of
1976, as amended, Holding having a minimum consolidated net worth, as defined,
at closing of not less than $52 million and funding of committed financing.
Odyssey has received financing commitments for the transactions from Bankers
Trust Corporation, whose commitments are subject to certain conditions.
 
    Simultaneously with the Merger, Holding and TransDigm will refinance all of
its existing debt (Note 9). The Merger, the refinancing, and payment of fees and
expenses are expected to be funded by (i) existing cash balances, (ii)
investments by Odyssey of $100.2 million, (iii) funds from a new $120 million
Senior Credit Facility, (iv) funds from $125 million senior subordinated notes
and (v) Holding PIK notes and additional common stock of $20 million issued to
certain stockholders. After consummation of the Merger, Holding anticipates that
it will have approximately $27.0 million available for working capital, certain
permitted acquisitions and for general corporate purposes under the new Senior
Credit Facility.
 
    Upon consummation of the Merger, Odyssey and its co-investors will own
approximately 73.7% of the Surviving Corporation's common stock and Kelso and
other continuing stockholders will own approximately 26.3% of the outstanding
shares of Holdings' common stock on a fully diluted basis.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
                 YEARS ENDED SEPTEMBER 30, 1998, 1997 AND 1996
 
1. DESCRIPTION OF THE BUSINESS AND MERGER (CONTINUED)
    During each of the years ended September 30, 1998, 1997 and 1996, TransDigm
paid Kelso a management fee of approximately $0.1 million.
 
2. ACQUISITION
 
    On August 8, 1997, TransDigm acquired all of the outstanding common stock of
Marathon for approximately $41.6 million in cash (including acquisition
expenses), $4 million of which was placed into two $2 million escrow accounts
(an environmental escrow and an indemnity escrow) to indemnify TransDigm in the
event certain defined environmental and other costs were incurred by Marathon or
TransDigm subsequent to the acquisition. At September 30, 1997, a post-closing
purchase price adjustment of approximately $.8 million was due from the seller
(see Note 4), which was received during November 1997 from the indemnity escrow.
The remainder of the indemnity escrow was released to the seller during the year
ended September 30, 1998. The environmental escrow account expires after the
occurrence of certain defined events in the Stock Purchase Agreement. During
September 1998, the seller filed a lawsuit against the Company to release the
environmental escrow alleging that the Company had violated the requirements of
the Stock Purchase Agreement relating to the investigation of the presence of
certain contaminants at the Marathon facility in Texas (Note 15). The Company
has filed counter claims against the seller and the ultimate outcome of this
matter cannot presently be determined.
 
    The acquisition has been accounted for using the purchase method and,
accordingly, the accompanying consolidated financial statements include the
operating results of Marathon since the date of the acquisition. The acquisition
was financed with available cash of approximately $11.6 million and the proceeds
of senior term debt of approximately $30 million. The excess of the aggregate
purchase price over the fair market value of net assets acquired of
approximately $28.9 million was recognized as goodwill.
 
    The following table summarizes the unaudited consolidated pro forma results
of operations, as if the acquisition had occurred at the beginning of the
following periods:

    This pro forma information does not purport to be indicative of the results

results.
 
3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    CONSOLIDATION--The accompanying consolidated financial statements include
the accounts of TransDigm Holding Company and subsidiaries (collectively the
"Company"). All significant intercompany balances and transactions have been
eliminated.
 
    SALES AND EARNINGS--The Company follows the guidelines of AICPA Statement of
Position 81-1, "Accounting for Performance of Construction-Type and Certain
Production-Type Contracts" (the contract method of accounting) for substantially
all commercial and governmental contracts. Under the contract method of
accounting, the Company's sales are primarily under fixed-price contracts,
certain of which require delivery of products over several years. Sales and
profit on each contract are recognized primarily in accordance with the
percentage-of-completion method of accounting, using the units of delivery
method. Revisions of estimated profits on contracts are included in earnings by
the reallocation method, which spreads the change in estimate over future
deliveries. Any anticipated losses on contracts are charged to earnings when
identified.
 
    CASH EQUIVALENTS--The Company considers all highly liquid investments with a
maturity of three months or less when purchased to be cash equivalents.
 
    ALLOWANCE FOR UNCOLLECTIBLE ACCOUNTS--The Company reserves for amounts
determined to be uncollectible based on specific identification and historical
experience.
 
    INVENTORIES--Inventories are stated at the lower of cost or market. Cost of
inventories is determined by the average cost and the first-in, first-out (FIFO)
methods. In accordance with industry practice, all inventories are classified as
current assets even though a portion of the inventories is not expected to be
realized within one year.
 
    PROPERTY, PLANT AND EQUIPMENT--Property, plant and equipment are stated at
cost. Depreciation is computed using the straight-line method at rates based on
the estimated useful lives of the assets.
 
    DEBT ISSUE COSTS AND DISCOUNTS--The cost of obtaining financing for the
acquisition as well as debt discounts are amortized using the interest method
over the respective terms of the related debt issues.
 
    INTANGIBLE ASSETS--Intangible assets are amortized on a straight-line basis
over their respective estimated useful lives ranging from 2 to 40 years. The
Company assesses the recoverability of intangibles by determining whether the
amortization over the remaining life can be recovered through projected
undiscounted cash flows from future operations.
 
    INCOME TAXES--The Company accounts for income taxes using an asset and
liability approach. Deferred taxes are recorded for the difference between the
book and tax basis of various assets and liabilities.
 
    PRODUCT WARRANTY COSTS--The Company provides a one year warranty on certain
products beginning on the date the product is installed on an aircraft. A
provision for estimated sales returns and the cost of repairs is recorded at the
time of sale and periodically adjusted to reflect actual experience.

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    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
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

    The Company's sales and receivables are concentrated in the aircraft
industry. The Company's customers consist primarily of original equipment
manufacturers of aircraft and aircraft subassemblies, commercial airlines,
distributors, and various agencies of the United States government, including
the U.S. military.
 
    For the year ended September 30, 1998, two customers represented
approximately 20% and 14%, respectively, of the Company's net sales. One
customer represented approximately 15% of the Company's net sales during the
year ended September 30, 1997 and a group of related customers represented
approximately 11% of the Company's net sales for the year ended September 30,
1996.
 
    Export sales were $17.8 million in 1998, $15.5 million in 1997 and $12.3
million in 1996.
 
    Approximately 9.6% of the Company's receivables at September 30, 1998 were
due from one customer and approximately 14.5% of the receivables were due from
entities which principally operate outside of the United States. Credit is
extended based on an evaluation of the customer's financial condition and
collateral is generally not required.

</TABLE>
 
    REVOLVING CREDIT, SWING LINE, AND TERM LOANS--During the year ended
September 30, 1997, the Company obtained a new $70 million credit facility with
a group of financial institutions which consist of a $20 million revolving
credit line (including $1 million of available swing line loans) and $50 million
of term loans. At September 30, 1998, the Company had $20 million of borrowings
(the entire revolving credit line) available under the credit facility. Any
amounts borrowed under the revolving credit and swing line loans mature in the
year 2003 and amounts borrowed under the term loans mature on various dates
through the year 2003.
 
    Borrowings under the credit facility bear interest at the Company's option
of (1) the Alternate Base Rate plus .25% or (2) the LIBO rate for Eurodollar
loans plus 1.25%, payable quarterly. The Alternate Base Rate is equal to the
highest of (a) the Prime Rate, (b) the Base CD Rate plus 1% or (c) the Federal
Funds Effective Rate plus .5%. The interest rate on outstanding borrowings at
September 30, 1998 was approximately 6.9%.
 
    Any amounts borrowed under the credit facility are collateralized by
substantially all of the tangible assets of the Company. The agreement also
contains a number of restrictive covenants that, among other things, limit the
ability of the Company to incur indebtedness, pay dividends, engage in mergers
and consolidations, engage in transactions with affiliates, make capital
expenditures, engage in sales of assets or the stock of a subsidiary company and
make certain investments. The agreement also requires the maintenance of a
minimum net worth as well as debt to adjusted earnings, interest coverage, and
other ratios.

9. DEBT (CONTINUED)
    The maturities of the Company's term loans are as follows: 1999--$5 million;
2000 through 2003-- $10 million each year.
 
    SUBORDINATED NOTES--During the year ended September 30, 1997, the Company
redeemed, in advance of their scheduled maturity, outstanding subordinated notes
which had a carrying value at the time of the redemption of approximately $19.3
million ($20 million principal balance net of an unamortized discount of
approximately $.7 million). As a result of the redemption, the Company
recognized an extraordinary loss of approximately $1.5 million (net of a current
income tax benefit of approximately $1 million) on the early extinguishment of
debt which included prepayment costs of approximately $.8 million and the
write-off of the remaining unamortized debt issue costs of approximately $1
million. The subordinated notes bore interest at an annual rate of 13%, payable
semi-annually.
 
    The subordinated notes included detachable warrants to purchase
approximately 16,000 shares of non-voting common stock of TransDigm Holding
Company at a price of $.10 per share which were not affected by the redemption
of the subordinated notes. The warrants are not exercisable except in connection
with the following triggering events: public offering of TransDigm Holding
Company's common stock, a business combination in which the Company is not the
surviving entity, and a change of control (see Note 1). If no transaction
constituting a triggering event is consummated prior to July 31, 1999, warrant
holders have the right to exercise a put option requiring the Company to
repurchase all of the warrants at their then appraised fair market value. If the
warrant holders have not exercised their put option prior to September 30, 2001,
then TransDigm Holding Company will have the right to call the warrants at their
then appraised fair market value.
 
10. RETIREMENT PLANS
 
    The Company has two non-contributory, defined benefit pension plans which
together cover all of its union employees. The plans provide benefits of stated
amounts for each year of service. The Company's funding policy is to contribute
actuarially determined amounts allowable under Internal Revenue Service
regulations. The plans' assets consist primarily of guaranteed investment
contracts with an insurance company.
 
    Net periodic pension cost of the defined benefit plans consists of the
following for the years ended September 30 (dollars in thousands):

</TABLE>
 
    The provisions of Financial Accounting Standards Board Statement No. 87,
"Employers' Accounting for Pensions" require recognition in the balance sheet of
an additional minimum liability and related intangible asset (limited by the
amount of unamortized prior service cost) for pension plans with accumulated
benefits in excess of plan assets. At September 30, 1998 and 1997, an additional
liability of $1.4 million and $.9 million, respectively, is reflected in the
consolidated balance sheets. At September 30, 1998 and 1997, the liability
exceeded the unrecognized prior service cost resulting in a charge to
stockholders' equity, net of taxes, of $.8 million and $.5 million,
respectively.
 
    The Company also sponsors a defined contribution employee savings plan which
covers substantially all of the Company's non-union employees. Under the plan,
the Company contributes a percentage of employee compensation and matches a
portion of employee contributions to the plan. The cost recognized for such
contributions under this plan for the years ended September 30, 1998, 1997 and
1996 was approximately $.6 million in all years.

</TABLE>
 
    The Company applies Accounting Principles Board Opinion No. 25 and related
interpretations in accounting for its stock option plans. No compensation cost
has been recognized for its stock option plans. Had compensation cost for the
Company's stock option plans been determined based on the fair value at the
grant dates for awards under those plans consistent with the method specified in
Statement of Financial Accounting Standards No. 123, the Company's net income
for the years ended September 30, 1998 and 1997 would have been reduced by
approximately $115,000 in both years.
 
    The weighted average fair value of options granted during fiscal 1997 and
1996 was $950,000 and $340,000, respectively. The fair value of the options
granted was estimated on the date of grant using the Black-Scholes
option-pricing model with the following assumptions for grants in both fiscal
1997 and 1996: risk-free interest rates ranging from 6.25% to 6.85%, expected
life of seven years, expected volatility and dividend yield of 0%.
 
13. LEASES
 
    TransDigm leases office space for its corporate headquarters and one of its
divisions. The lease requires rental payments of approximately $200,000 per year
through the initial term of the lease, which expires in 1999. TransDigm may also
be required to share in the operating costs of the facility under certain
conditions. TransDigm has the option to renew the lease for an additional five
years beyond the expiration of the initial lease term. TransDigm also has
commitments under operating leases for vehicles and equipment. Rental expense
was $599,000 in 1998, $540,000 in 1997, and $570,000 in 1996. Future, minimum
rental commitments at September 30, 1998 under operating leases having initial
or remaining non-cancelable lease terms exceeding one year are $383,000 in 1999,
$166,000 in 2000, $79,000 in 2001, and $29,000 in 2002.
 
14. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The carrying value of the Company's cash and cash equivalents, accounts
receivable and payable, and accrued liabilities approximate their fair value due
to the short-term maturities of these assets and liabilities. The Company also
believes that the aggregate fair value of its term loans approximates its
carrying amount because the interest rates on the debt are reset on a frequent
basis to reflect current market rates.

15. CONTINGENCIES
 
    ENVIRONMENTAL--The soil and groundwater beneath the Company's facility in
Waco, Texas have been impacted by releases of hazardous materials. The resulting
contaminants of concern have been delineated and characterized. Because the
majority of these contaminants are presently below action levels prescribed by
the Texas Natural Resources Conservation Commission ("TNRCC"), and because an
escrow (Note 2) was previously funded to cover the cost of remediation that
TNRCC might require for those contaminants currently in excess of action limits,
management does not believe the condition of the soil and groundwater at the
Waco facility will require incurrence of material expenditures.
 
    OTHER--While the Company is currently involved in certain legal proceedings,
management believes the results of these proceedings will not have a material
effect on the financial condition, results of operations or cash flows of the
Company. During the ordinary course of business, the Company is from time to
time threatened with, or may become a party to, legal actions and other
proceedings. The Company believes that its potential exposure to such legal
actions is adequately covered by its aviation product and general liability
insurance.
 
16. NEW ACCOUNTING STANDARDS
 
    In June 1997, the Financial Accounting Standards Board issued SFAS No. 130,
"Reporting Comprehensive Income." The statement requires that an enterprise
classify items of other comprehensive income by their nature in a financial
statement and display the accumulated balance of other comprehensive income
separately from retained earnings and additional paid-in capital in the equity
section of a statement of financial position. The Company will adopt this
standard during fiscal 1999.
 
    In June 1997, the Financial Accounting Standards Board issued SFAS No. 131,
"Disclosures About Segments of an Enterprise and Related Information." The
statement requires that a public business enterprise report financial and
descriptive information about its reportable operating segments such as a
measure of segment profit or loss, certain specific revenue and expense items,
and segment assets. The Company will adopt this standard during fiscal 1999.
 
    In February 1998, the Financial Accounting Standards Board issued SFAS No.
132, "Employer's Disclosures about Pensions and Other Postretirement Benefits."
The statement requires an enterprise to disclose certain information about its
pension and postretirement benefits, including a reconciliation of beginning and
ending balances of the benefit obligation, the funded status of the plans, and
the amount of net periodic benefit cost recognized. The Company will adopt this
standard during fiscal 1999.
 
    In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities." This statement
establishes accounting and reporting standards for derivative instruments
embedded in other contracts (collectively referred to as derivatives), and for
hedging activities. It requires that an entity recognize all derivatives as
either assets or liabilities in the statement of financial position and measure
those instruments at fair value. If certain conditions are met, a derivative may
be specifically designated as (a) a hedge of the exposure to changes in the fair
value of a recognized asset or liability or an unrecognized firm commitment, (b)
a hedge of the exposure to variable cash flows of a forecasted transaction, or
(c) a hedge of the foreign currency exposure of a net investment in a foreign
operation, an unrecognized firm commitment, an

available-for-sale security, or a foreign-currency-denominated forecasted
transaction. The Company will adopt this standard during fiscal 2000.
 
    While management has not completed its analysis of these new accounting
standards, the adoption of these standards is not expected to have a material
effect on the Company's financial statements.
 
17. ACCOUNTING CHANGE
 
    In connection with the planned registration of the Senior Subordinated Notes
described in Note 1 with the Securities and Exchange Commission ("Commission"),
the Company has retroactively adopted a new method of accounting for the put
warrants issued in 1993 (see Note 9). The Company adopted the new method to
comply with the requirements of the Commission for put warrants. Under the new
method of accounting, the Company has recorded a liability for the estimated put
value of the warrants and is recognizing changes in the estimated put value in
earnings. Previously, the Company recognized the warrants as a component of
stockholders' equity and adjusted the carrying value of the warrants on a
straight-line basis for the difference between their original recorded amount of
$1.6 million and their estimated put value in July 1999, with an offsetting
charge to the Company's retained earnings (deficit). The Company has restated
its 1997 and 1996 consolidated financial statements for this change in
accordance with the provisions of Accounting Principles Board Opinion No. 20,
"Accounting Changes." The significant effects of the change in accounting on the
Company's consolidated statements of income and retained earnings (deficit) are
as follows (dollars in thousands):

As previously reported:
  Income before extraordinary loss.........................................  $   9,434  $   3,335
  Net income...............................................................      7,972      3,335
As restated:
  Income before extraordinary loss.........................................      4,634      1,175
  Net income...............................................................      3,172      1,175
</TABLE>
 
    Because the Merger described in Note 1 constitutes a "triggering event"
pursuant to the terms of the warrants, the warrant holders will be permitted to
exercise their put option in connection with the closing of the transaction.
Accordingly, the Company has adjusted the carrying value of the warrants in the
accompanying September 30, 1998 consolidated balance sheet to their estimated
fair value.
 
18. SUBSEQUENT EVENT
 
    The Merger described in Note 1 was completed on December 3, 1998.

To the Board of Directors and Shareholders
of Marathon Power Technologies Company
 
In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations and retained earnings and of cash flows
present fairly, in all material respects, the financial position of Marathon
Power Technologies Company and its subsidiary at December 31, 1996 and 1995, and
the results of their operations and their cash flows for the years then ended,
in conformity with generally accepted accounting principles. 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 audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards which require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are
free from material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. BUSINESS AND FORMATION
 
    Marathon Power Technologies Company ("Company") was organized in March 1994
and purchased substantially all of the net assets of Marathon Power
Technologies, a wholly-owned subsidiary of American Premier Underwriters, Inc.,
on May 19, 1994. The Company, located in Waco, Texas, manufactures vented and
sealed nickel cadmium rechargeable batteries which are used in aviation and
consumer electrical equipment. The Company also manufactures static inverters,
used largely in the aviation industry, which convert DC power into AC power, as
well as other items, such as battery chargers. The Company maintains a
subsidiary in the United Kingdom used primarily for distribution of vented
products.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    The Company's significant accounting policies are as follows:
 
    PRINCIPLES OF CONSOLIDATION--The financial statements include the accounts
of the Company and its wholly-owned subsidiary after elimination of intercompany
transactions and balances. Certain reclassifications were made to conform prior
year amounts to the current year presentation.
 
    USE OF ESTIMATES--Financial statements prepared in conformity with generally
accepted accounting principles require management to make estimates and
assumptions about reported amounts of assets and liabilities; disclosure of
contingent assets and liabilities and reported amounts of revenues and expenses.
Management must also make estimates and judgments about future results of
operations related to specific elements of the business in assessing
recoverability of assets and recorded values of liabilities. Actual results
could differ from those estimates.
 
    CASH AND CASH EQUIVALENTS--Cash and cash equivalents include cash on hand
and short-term investments with original maturities of three months or less.
 
    CREDIT CONCENTRATIONS--The Company sells products chiefly to aviation
companies and/or suppliers to aviation companies, generally on an unsecured
basis. The Company provides estimated reserves against accounts receivable for
collection losses.
 
    INVENTORIES--Inventories are stated at the lower of cost or market, cost
being determined on a first-in first-out basis.
 
    PROPERTY PLANT AND EQUIPMENT--Property, plant and equipment, including
assets under capital lease, are carried at acquisition cost. Depreciation and
amortization are computed on the straight-line basis over the estimated
remaining useful lives of the assets (ranging from 2 to 30 years) and the
remaining term of capital leases, respectively. Repair and maintenance
expenditures are charged to operations as incurred, and expenditures for major
renewals and betterments are capitalized. When units of property are disposed,
the cost and related accumulated depreciation are removed from the accounts, and
the resulting gains or losses are included in operations.
 
    REVENUE RECOGNITION--Sales revenue and related cost of sales are recognized
as products are shipped to customers. In the normal course of business, the
Company provides for product defects through the issuance of one to two year
warranties covering its products. The costs associated with these warranties are
accrued at the time of sale which totaled $130,000 and $232,000 in 1996 and
1995, respectively.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    INCOME TAXES--Deferred income taxes are provided for differences between tax
laws and financial accounting standards regarding the recognition and
measurement of assets, liabilities, revenues and expenses. Such differences
result principally from different methods of purchase price allocation for tax
and financial accounting purposes and depreciation.
 
    FAIR VALUE OF FINANCIAL INSTRUMENTS--Management believes the recorded values
of financial instruments approximate their current fair values as such items are
current in nature and/or generally bear variable interest rates which adjust
yield to derive current market value.
 
    STOCK-BASED COMPENSATION--In October 1995, Statement of Financial Accounting
Standards No. 123, "Accounting for Stock-based Compensation" ("SFAS 123") was
issued. This statement requires the fair value of stock options and other
stock-based compensation issued to employees to either be included as
compensation in the statement of operations, or the pro forma effect on net
income of such compensation expense to be disclosed in the footnotes to the
Company's financial statements commencing with the Company's year ending
December 31, 1996. The Company has adopted SFAS 123 on a disclosure basis only.
As such, implementation of SFAS 123 is not expected to impact the Company's
consolidated balance sheet or consolidated statement of operations.

of .25% per annum of the daily average of the unused portion of the revolving
credit facility. Prior to October 1996, the commitment fee paid was .5%.
 
    The above debt is secured by the Company's assets and common stock and is
restricted by certain financial covenants including capital base, debt ratio and
current ratio requirements, among others.

6. LONG-TERM DEBT (CONTINUED)
    In 1996, the Company extinguished its $2,500,000 subordinated note payable
for a cash payment of $2,125,000, obtained from a combination of operating cash
flows and an increase in borrowings under the line of credit. The difference
between the carrying amount of the note and the cash paid to the holder of such
borrowings (and related expenses of $10,000) was recorded as an extraordinary
gain on the early extinguishment of debt of $365,000 ($230,000 net of income
taxes). The effective tax rate for the extraordinary gain was 37.0%.
 
    Aggregate maturities of long-term debt as of December 31, 1996 are as

market value of common stock at the time the option is granted. Both
nonqualified stock options and incentive stock options, as defined by the
Internal Revenue Code of 1986, as amended, may be granted under the plan. The

</TABLE>
 
    As of December 31, 1996 and 1995, options for 1,609 and 1,012 shares,
respectively, were exercisable under the Company's stock option plan.
 
    The fair market values of options as of their grant dates were approximately
$49 and $42 per option in December 1996 and 1995, respectively, based on
comparison of the fair market value of the underlying shares and the net present
value of the exercise price over the period of exercisability at a risk free
market rate of 7.9% and 5.7%, respectively. No dividend payments or volatility
in stock prices were assumed in the fair market value calculations.

11. STOCK OPTIONS (CONTINUED)
    No compensation expense was recorded during 1996 or 1995 for options issued
under the plan since the Company accounts for such transactions in accordance
with APB Opinion No. 25, "Accounting for Stock Issued to Employees." Had the
Company included the stock-based compensation in the consolidated statement of
operations, $17,000 and $28,000 in additional employee compensation expenses,
net of the effect of income taxes, would have been recorded in 1996 and 1995,
respectively. This would result in pro forma net income of $2,413,000 and
$1,378,000, respectively.
 
12. EMPLOYEE BENEFITS
 
    The Company sponsors a defined contribution retirement plan for Company
employees. Employees are eligible to participate in the plan on the first day of
the calendar quarter following their employment date. The Company makes annual
contributions to the plan equal to 50% of the employees contribution (up to a
maximum of 6% of each employee's compensation). The Company's expense under this
plan was $68,000 and $62,000 in 1996 and 1995, respectively.
 
    The Company sponsors a self-funded employee welfare benefit plan which
provides comprehensive medical benefits to Company employees and their
dependents. All full-time employees become eligible on the first day of the
month following the month in which they complete 30 days of service. The Company
incurred expenses of $366,000 and $304,000 under this plan during the years
ended December 31, 1996 and 1995, respectively.
 
13. COMMITMENTS AND CONTINGENCIES
 
    Under the terms of the May 19, 1994 asset purchase agreement, the Company is
indemnified for any preacquisition environment remediation costs. The Company
had accrued $36,000 and $25,000 at December 31, 1996 and 1995, respectively, for
additional hazardous waste disposal costs.
 
    The Company is party to certain legal proceedings incidental to its
business. Certain claims arising in the ordinary course of business have been
filed or are pending against the Company. Management does not believe the
outcome of any of these proceedings will materially affect the Company's
financial position or results of operations. Under the terms of the May 19, 1994
asset purchase agreement, the Company is indemnified for any preacquisition
legal costs. The Company accrues for claims that are both probable and for which
expected loss can be reasonably estimated.

    Section 145 of the General Corporation Law of the State of Delaware ("DGCL")
provides that a corporation has the power to indemnify any director or officer,
or former director or officer, 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) against the expenses (including
attorney's fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by him in connection with the defense of any action by
reason of being or having been directors or officers, if such person shall have
acted in good faith and in a manner reasonably believed to be in or not opposed
to the best interests of the corporation, and, with respect to any criminal
action or proceeding, provided that such person had no reasonable cause to
believe his conduct was unlawful, except that, if such action shall be in the
right of the corporation, no such indemnification shall be provided as to any
claim, issue or matter as to which such person shall have been judged to have
been liable to the corporation unless and only to the extent that the Court of
Chancery of the State of Delaware (the "Court of Chancery"), or any court in
such suit or action was brought, shall determine upon application that, despite
the liability judgment, but in view of all of the circumstances of the case,
such person is fairly and reasonably entitled to indemnity for such expenses as
the Court of Chancery or such other court shall deem proper.
 
    Accordingly, each of (i) the Restated Certificate of Incorporation (dated
September 28, 1993) and the amendments thereto (dated December 21, 1993) of
TransDigm Holding Company (filed herewith as Exhibits 3.1 and 3.2,
respectively), (ii) the Certificate of Incorporation (dated July 2, 1993) and
the amendments thereto (dated July 22, 1993) of TransDigm Inc. (filed herewith
as Exhibits 3.4 and 3.5, respectively), (iii) the Certificate of Incorporation
(dated March 28, 1994) and the amendments thereto (dated May 18, 1994 and May
24, 1994) of Marathon Power Technologies Company (filed herewith as Exhibits
3.7, 3.8 and 3.9, respectively), provide that subject to certain exceptions,
TransDigm Holding Company, TransDigm Inc. and Marathon Power Technologies
Company (collectively, the "Co-Registrants" and, individually, the
"Co-Registrant") shall indemnify each of its respective director or officer
against any and all expenses (including attorneys' fees), judgments, fines,
excise taxes assessed with respect to any employee benefit plan, or penalties
and amounts paid in settlement actually and reasonably incurred by such director
or officer in connection with any threatened, pending or completed action, suit
or proceeding, whether civil, criminal, administrative or investigative
(including an action by or in the right of such Co-Registrant), to which such
director or officer is, was or at any time becomes a party, or is threatened to
be made a party, by reason of the fact that such director or officer is, was or
at any time becomes a director or officer of such Co-Registrant, or is, or was
serving, or at any time serves at the request of such Co-Registrant as a
director or officer of another corporation, partnership, joint venture, trust or
other enterprise. The Restated Certificate of Incorporation or the Certificate
of Incorporation, as applicable, and the amendments thereto also provide that
the respective Co-Registrant shall advance expenses (including attorneys' fees)
actually and reasonably incurred by its director or officer in defending any
proceeding and any judgments, fines or amounts to be paid in settlement thereof.
The Restated Certificate of Incorporation or the Certificate of Incorporation,
as applicable, and the amendments thereto provide, however, that the foregoing
provisions shall not require the respective Co-Registrant to pay any indemnity
(i) for which payment is actually made to such director or officer under a valid
and collectible insurance policy, except in respect of any excess beyond the
amount of payment under such insurance; (ii) for which such director or officer
is indemnified by the respective Co-Registrant pursuant to applicable law or
otherwise than pursuant to the Restated Certificate of Incorporation or the
Certificate of Incorporation, as applicable, of the respective Co-Registrant;
(iii) for an accounting of profits made from the purchase or sale by such
director or officer of securities of the respective Co-Registrant within the
meaning of
 
                                      II-1
<PAGE>
Section 16(b) of the Securities Exchange Act of 1934 and amendments thereto or
similar provisions of any state statutory law or common law; (iv) on account of
such director's or officer's conduct which is finally adjudged by a court to
have been knowingly fraudulent, deliberately dishonest or willful misconduct; or
(v) if a final decision by a court having jurisdiction in the matter shall
determine that such indemnity is not lawful. Such indemnification shall not be
deemed exclusive of any other rights to which a director or officer seeking
indemnification may be entitled under any statute, the Bylaws, other provisions
of the Restated Certificate of Incorporation or the Certificate of
Incorporation, as applicable, of the respective Co-Registrant, agreement, vote
of stockholders or disinterested directors or otherwise, both as to action in
such director's or officer's official capacity and as to action in any other
capacity while holding such office.
 
    Furthermore, a director of a Co-Registrant shall not be liable to the
respective Co-Registrant or its stockholders for monetary damages for breach of
fiduciary duty as a director, except for liability (a) for any breach of the
director's duty of loyalty to the respective Co-Registrant or its stockholders,
(b) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (c) for the unlawful payment of a
dividend, unlawful stock purchase or unlawful redemption, (d) for any
transaction from which the director derived an improper personal benefit, or
such exemption from liability or limitation thereof is not permitted under the
DGCL as currently in effect or as the same may hereafter be amended.

ITEM 22. UNDERTAKINGS.
 
    Each of the undersigned Co-Registrants hereby undertakes that insofar as
indemnification for liabilities arising under the Securities Act of 1933 may be
permitted to directors, officers and controlling persons of the respective
Co-Registrant pursuant to the foregoing provisions described under Item 20
above, or otherwise, the respective Co-Registrant has been advised that in the
opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Securities Act of 1933 and is,
therefore, unenforceable. In the event that a claim of indemnification against
such liabilities (other than the payment by the respective Co-Registrant of
expenses incurred or paid by a director, officer or controlling person of such
Co-Registrant in the successful defense of any action, suit paid by a director,
officer or controlling person of such Co-Registrant in the successful defense of
any action, suit or proceeding) is asserted against such Co-Registrant by such
director, officer or controlling person in connection with the securities being
registered, such Co-Registrant 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 of whether such indemnification by it is
against public policy as expressed in the Securities Act of 1933 and will be
governed by the final adjudication of such issue.
 
    Each of the undersigned Co-Registrants hereby undertakes (i) to respond to
requests for information that is incorporated by reference into this Prospectus
pursuant to Items 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 other equally prompt means. This undertaking also includes documents
filed subsequent to the effective date of the Registration Statement through the
date of responding to the request.
 
    Each of the undersigned Co-Registrants hereby undertakes 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.
 
    Each of the undersigned Co-Registrants hereby undertakes to file, during any
period in which offers or sales are being made, a post-effective amendment to
this registration statement: (i) to include any prospectus required by Section
10(a)(3) of the Securities Act of 1933; (ii) to reflect in the prospectus any
facts or events arising after the effective date of the registration statement
(or the most recent post-effective amendment thereof) which, individually or in
the aggregate, represent a fundamental change in the information set forth in
the registration statement (notwithstanding the foregoing, any increase or
decrease in volume of securities offered (if the total dollar value of
securities offered would not exceed that which was registered) and any deviation
from the low or high end of the estimated maximum offering range may be
reflected in the form of prospectus filed with the Commission pursuant to Rule
424(b) if, in the aggregate, the changes in volume and price represent no more
than 20 percent change in the maximum aggregate offering price set forth in the
"Calculation of Registration Fee" table in the effective registration
statement); and (iii) to include any material information with respect to the
plan of distribution not previously disclosed in the registration statement or
any material change to such information in the registration statement.
 
    Each of the undersigned Co-Registrants hereby undertakes as follows: that
prior to any public reoffering of the securities registered hereunder through
use of a prospectus which is a part of this Registration Statement, by any
person or party who is deemed to be an underwriter within the meaning of Rule
145(c), the issuer undertakes that such reoffering prospectus will contain the
information called
 
                                      II-5
<PAGE>
for by the applicable registration form with respect to reofferings by persons
who may be deemed underwriters, in addition to the information called for by the
other Items of the application form.
 
    Each of the undersigned Co-Registrants hereby undertakes that every
prospectus: (i) that is filed pursuant to the immediately preceding paragraph or
(ii) that purports to meet the requirements of Section 10(a)(3) of the
Securities Act of 1933, as amended, and is used in connection with an offering
of securities subject to Rule 415, will be filed as a part of an amendment to
the registration statement and will not be used until such amendment is
effective, and that, for purposes of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
    Each of the undersigned Co-Registrants hereby undertakes to remove from
registration by means of a post-effective amendment any of the securities being
registered which remain unsold at the termination of the exchange offer.

of the Co-Registrants has duly caused this Registration Statement to be signed
on its behalf by the undersigned, thereunto duly authorized, in the City of
Waco, State of Texas, on February 5, 1999.

                  WHEREAS, Holdings, the Borrower, the Existing Lenders and the
Agent are parties to a Credit Agreement, dated as of December 3, 1998 (the
"Credit Agreement"); and

                  WHEREAS, the parties hereto wish to amend the Credit Agreement
as herein provided;

                  NOW, THEREFORE, it is agreed:

                  1. Each of the Existing Lenders severally and not jointly
hereby sells and assigns to each of the New Lenders without recourse and without
representation or warranty (other than as expressly provided herein), and each
New Lender hereby purchases and assumes from each of the Existing Lenders, that
interest in and to each of such Existing Lender's rights and obligations in
respect of those Tranches of Loans set forth on Schedule B hereto under the
Credit Agreement as of the date hereof which in the aggregate represents such
New Lender's PRO RATA share (for each such New Lender, its "Pro Rata Share") in
such Tranches of Loans as set forth on such Schedule B (calculated after giving
effect to this Amendment), and such Pro Rata Share represents all of the
outstanding rights and obligations under the Credit Agreement in respect of the
Tranches of Loans that are being sold and assigned to each New Lender pursuant
to this Amendment, including, without limitation, in the case of any assignment
of outstanding A Term Loans, B Term Loans and/or portion of the Total Revolving

                  3. On and after the First Amendment Effective Date, Annex II

and inserting in lieu thereof a new Annex II in the form of Schedule D hereto.

                  4. Each Existing Lender (i) represents and warrants that it is
the legal and beneficial owner of the interest being assigned by it hereunder
and that such interest is free and clear of any adverse claim; (ii) makes no
representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with the
Credit Agreement or the other Credit Documents or the execution, legality,

Agreement or the other Credit Documents or any other instrument or document
furnished pursuant thereto; and (iii) makes no representation or warranty and
assumes no responsibility with respect to the financial condition of Holdings or
any of its Subsidiaries or the performance or observance by Holdings or any of
its Subsidiaries of any of their obligations under the Credit Agreement or the
other Credit Documents to which any such Person is a party or any other
instrument or document furnished pursuant thereto.

                  5. Each New Lender (i) confirms that it has received a copy of
the Credit Agreement and the other Credit Documents, together with copies of the
financial statements referred to therein and such other documents and
information as it has deemed appropriate to make its own credit analysis and
decision to enter into this Amendment; (ii) agrees that it will, independently
and without reliance upon the Agent or any other Lender and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own credit decisions in taking or not taking action under the Credit
Agreement; (iii) confirms that it is an Eligible Transferee under Section
13.04(b) of the Credit Agreement; (iv) appoints and authorizes the
Administrative Agent and the Collateral Agent to take such action as agent on
its behalf and to exercise such powers under the Credit Agreement and the other
Credit Documents as are delegated to the Administrative Agent and the Collateral
Agent by the terms thereof, together with such powers as are reasonably
incidental thereto; (v) agrees that it will perform in accordance with their
terms all of the obligations which by the terms of the Credit Agreement are
required to be performed by it as a Lender; and (vi) to the extent legally
entitled to do so, agrees to promptly submit the forms described in Section
13.04(b) of the Credit Agreement.

                  6. Each of the Existing Lenders, the New Lenders and the
Administrative Agent hereby agree that (A) all amounts accrued with respect to
the A Term Loans, B Term Loans, outstanding Revolving Loans and the Total
Unutilized Revolving Loan Commitment prior to the delivery by such New Lender of
the amount referred to in clause (ii) of Section 11 of this Amendment shall be
for the account of the Existing Lenders, respectively, and that all such amounts
accrued on and after the delivery of such amounts referred to in clause (ii) of
such Section 11 shall be for the account of such New Lender based upon its
relevant Pro Rata Share and (B) the Documentation Agent shall not have any
duties under the Credit Documents other than in its capacity as a Lender except

Effective Date with the consent of the Documentation Agent.

Lender shall become a "Lender" under, and for all purposes of, the Credit
Agreement and the other Credit Documents and the Administrative Agent shall
record the transfers contemplated hereby in the Register.

                  8. This Amendment is limited as specified and shall not

PARTIES HEREUNDER SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAW

respective accounts of the Existing Lenders, an amount equal to such New

become effective notwithstanding such failure, provided that (x) Schedule C
shall be modified to delete any such New Lender and such New Lender's relevant
Pro Rata Share shall be reallocated among the Existing Lenders in such manner as
the Existing Lenders shall agree and (y) the signature pages of this Amendment
shall be deemed revised to delete such New Lender's name therefrom.

                  13. From and after the First Amendment Effective Date, all
