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 niche individual aircraft component
markets that we estimate range in size from $10 million to $100 million in
annual revenues. For fiscal 1998 on a pro forma basis after giving effect to the
offering of the Old Notes, the recapitalization of Holdings, Odyssey's equity
investment in Holdings, the issuance of Holdings' pay-in-kind notes, the
acquisition of ZMP, Inc. and the related borrowings under the new credit
facility as if they had occurred on October 1, 1997, we would have generated net
sales, operating income and EBITDA, As Defined, of $145.0 million, $39.3 million
and $49.0 million, respectively. For the thirteen weeks ended January 1, 1999 on
a pro forma basis as if those transactions had occurred on October 1, 1998, we
would have generated net sales, operating income and EBITDA, As Defined, of
$37.9 million, $10.3 million and $12.8 million, respectively.
    
 
   
    Our business is comprised of four business units: (1) AdelWiggins Group, (2)
AeroControlex Group, (3) Marathon Power Technologies Company, and (4) Adams Rite
Aerospace, Inc., 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. Adams Rite Aerospace manufactures
mechanical hardware, fluid controls, lavatory hardware, electromechanical
controls and oxygen systems related products. TransDigm Inc. was formed in 1993
through a management-led buyout of the Aerospace Components Group of IMO
Industries Inc. In addition, Marathon and ZMP, Inc., the corporate parent of
Adams Rite Aerospace, were acquired in August 1997 and April 1999, respectively,
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.
 
- -   GENERATE NEW BUSINESS INITIATIVES. We intend to continue to aggressively
    pursue growth opportunities through our new business initiatives,
    particularly in the aftermarket.
 
- -   REALIZE PRODUCTIVITY SAVINGS. We will continue to focus on improving our
    operating margins through manufacturing improvements and increases in
    employee productivity.
 
- -   PURSUE STRATEGIC ACQUISITIONS. We intend to aggressively pursue acquisitions
    that we believe will allow us to enhance value, reduce costs and develop new
    business.

RECENT DEVELOPMENTS
 
    At the same time as the offering of the Old Notes by TransDigm, Holdings
consummated a recapitalization. The former equity holders of Holdings received a
payment in the recapitalization of $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.
 
    As part of the recapitalization, Odyssey Investment Partners Fund, LLC and
its co-investors invested $100.2 million of cash equity in Holdings. As a result
of the recapitalization, 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.
 
   
    On April 23, 1999, TransDigm acquired ZMP, Inc., the corporate parent of
Adams Rite Aerospace, through a merger. The purchase price for the acquisition
was $41 million, subject to post-closing purchase price adjustments. The
acquisition was funded entirely through additional borrowings under the new
credit facility. As a result of the acquisition, ZMP and Adams Rite Aerospace
became wholly-owned subsidiaries of TransDigm.
    
 
ODYSSEY INVESTMENT PARTNERS FUND, LLC
 
   
    As a result of the recapitalization, TransDigm is controlled by Odyssey, a
private equity fund engaged in making investments in established, middle market
companies. Although Odyssey was formed in 1997, its principals collectively have
over 70 years of private equity experience.

                                      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, Marathon, ZMP and Adams Rite
                                      Aerospace (together, 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 you without
                                      compliance with the registration and prospectus
                                      delivery requirements of the Securities Act, unless
                                      you:
 
                                      - are an "affiliate" of ours or the Guarantors within
                                      the meaning of Rule 405 under the Securities Act;
 
                                      - are a broker-dealer who purchased Old Notes
                                      directly from us for resale under Rule 144A or any
                                        other available exemption under the Securities Act;
 
                                      - acquired the New Notes other than in the ordinary
                                        course of your business; or
 
                                      - have an arrangement with any person to engage in
                                      the 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, you must make the
                                      appropriate representations in the letter of
                                      transmittal that we are sending you with this
                                      prospectus.
 
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. At the
                                      same time, we entered into a registration rights
                                      agreement with the initial purchasers requiring us to
                                      make the exchange offer. The registration rights
                                      agreement also requires us and the Guarantors to:
 
                                      - cause the registration statement filed with respect
                                      to the exchange offer to be declared effective by May
                                        2, 1999; and
 
                                      - consummate the exchange offer by June 6, 1999.

                                      do not do so, the interest rate on the Old Notes will
                                      increase initially by 0.50%.

                                      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 the Old Notes tendered and accepted

                                      Under certain circumstances specified in the

                                      Offer."
 
Exchange Agent......................  State Street Bank and Trust Company 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 in
                                      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 their
                                      existing transfer restrictions. We will have no
                                      further obligation to provide for registration under
                                      the Securities Act of such Old Notes.

<TABLE>
<S>                                            <C>
Securities Offered...........................  $125,000,000 in aggregate principal amount of
                                               senior subordinated notes.
 
Guarantees...................................  Holdings, the parent holding company of
                                               TransDigm, will fully and unconditionally
                                               guarantee the New Notes. However, you should
                                               not rely upon the guarantee by Holdings
                                               because Holdings has no assets other than its
                                               equity interest in TransDigm. In addition,
                                               our domestic subsidiaries will fully and
                                               unconditionally guarantee the New Notes on a
                                               joint and several basis with Holdings.
 
                                               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 our unsecured senior
                                               subordinated obligations 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 January 1, 1999 on a pro
                                               forma basis after giving effect to the
                                               acquisition of ZMP and the related borrowings
                                               under the new credit facility as if they had
                                               occurred on January 1, 1999, we and our
                                               subsidiaries would have had $133.0 million of
                                               senior debt, excluding approximately $21.0
                                               million that we would have had available to
                                               borrow under our New Credit Facility, and
                                               Holdings would have had $153.2 million of
                                               senior debt.
 
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

Optional Redemption after Public Equity        At any time and from time to time before
  Offerings..................................  December 1, 2001, we can choose to buy back
                                               up to 35% of the outstanding Notes with money
                                               that we raise in certain types of equity
                                               offerings, as long as:
 
                                               -  we pay 110.375% of the face amount of the
                                                  Notes, plus accrued interest;
 
                                               -  we buy the Notes back within 120 days of
                                                  completing such equity offering; and

Change of Control Offer......................  If a change in control of TransDigm or
                                               Holdings 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

          SUMMARY CONSOLIDATED HISTORICAL AND PRO FORMA FINANCIAL DATA
 
   
    The following table sets forth summary historical and pro forma consolidated
financial information of Holdings. 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 financial data as of and for the thirteen weeks ended January 1,
1999 and December 26, 1997 has been derived from Holdings' unaudited
consolidated financial statements for those periods, which, in the opinion of
management, include all adjustments, consisting only of normal recurring
adjustments, necessary for a fair presentation of the results of operations,
financial position, and cash flows. The results for the thirteen weeks ended
January 1, 1999 are not necessarily indicative of results that may be expected
for the entire year. Separate financial information for TransDigm is not
presented since the New Notes will be guaranteed by Holdings and all direct and
indirect subsidiaries of TransDigm, and since Holdings has no operations or
assets separate from its investment in TransDigm.
    
 
   
    The pro forma statement of operations data and the pro forma other financial
data set forth below give effect to the offering of the Old Notes, the
recapitalization of Holdings, Odyssey's equity investment in Holdings, the
issuance of Holdings' pay-in-kind notes, the acquisition of ZMP and the related
borrowings under the new credit facility as if they had occurred at the
beginning of the period. The pro forma balance sheet data set forth below give
effect to the acquisition of ZMP and the related borrowings under the new credit
facility as if they had occurred as of the balance sheet date. ZMP's fiscal year
1998 ended on June 26, 1998. The pro forma financial information is not
necessarily indicative of either future results of operations or the results
that might have occurred if the applicable 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. The acquisition
was accounted for as a purchase. The results of operations of Marathon are
included in Holdings' consolidated historical financial statements from the date
of such acquisition. The acquisition of ZMP will also be accounted for as a
purchase.
    
 
   
    You should read the following table together with the "Unaudited Pro Forma
Consolidated Financial Information" 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 included
elsewhere in this prospectus.

(1) Operating income (loss) includes the effect of 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.
 
   
(2) The interest expense reported for fiscal 1996 through 1998 represents
    interest expense of TransDigm. Holdings had no interest expense prior to the
    Recapitalization. After the Recapitalization, Holdings has incurred interest
    expense relating to the Holdings PIK Notes and Holdings has no other
    interest expense. TransDigm is not an obligor or a guarantor under the
    Holdings PIK Notes. Pro forma interest expense and historical interest
    expense for the Holdings PIK Notes for the thirteen weeks ended January 1,
    1999 were $600 and $200, respectively. Pro forma EBITDA, As Defined to
    interest expense of TransDigm, which excludes the Holdings PIK Notes, for
    fiscal 1998 and the thirteen weeks ended January 1, 1999 was 1.9x and 2.0x,
    respectively.
    
 
(3) EBITDA represents earnings before interest, taxes, depreciation,
    amortization, warrant put value adjustments and extraordinary items. EBITDA
    is presented because management believes it is frequently used by securities
    analysts, investors and other interested parties in the evaluation of
    companies in Holdings' industry. However, other companies in Holdings'
    industry may calculate EBITDA differently than Holdings does. EBITDA is not
    a measurement of financial performance under generally accepted accounting
    principles and should not be considered as an alternative to cash flow from
    operating activities, as a measure of liquidity or an alternative to net
    income as indicators of Holdings' operating performance or any other
    measures of performance derived in accordance with generally accepted
    accounting principles. See Holdings' Consolidated Statements of Cash Flows
    included in Holdings consolidated financial statements.

   EBITDA, As Defined, is presented herein to provide additional information
    with respect to the ability of Holdings to satisfy its debt service, capital
    expenditure and working capital requirements and because certain types of
    covenants in TransDigm's and Holdings' borrowing arrangements are tied to
    similar measures. While EBITDA-based measures are frequently used as
    measures of operations and the ability to meet debt service requirements,
    they are not necessarily comparable to other similarly titled captions of
    other companies due to differences in methods of calculation.
 
(5) 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 $32,390 for the thirteen weeks ended
    January 1, 1999.

In addition, Holdings has an additional $20.2 million of indebtedness
represented by the value of the Holdings' pay-in-kind notes, all of which will
be senior to Holdings' guarantee of these New Notes. As at January 1, 1999 on a
pro forma basis assuming we had completed the acquisition of ZMP and the related
borrowings under the new credit facility on January 1, 1999, Holdings would have
had a stockholders' deficit of approximately $136.2 million. See "Unaudited Pro
Forma Consolidated Financial Information." Holdings' ratio of earnings to fixed
charges for the fiscal year ended September 30, 1998 and the thirteen weeks
ended January 1, 1999, in each case, on a pro forma basis assuming we had
completed (1) the offering of the Old Notes, (2) the recapitalization of
Holdings, (3) Odyssey's equity investment in Holdings, (4) the issuance of
Holdings' pay-in-kind notes, (5) the acquisition of ZMP and (6) the related
borrowings under the new credit facility at the beginning of the period
specified below would have been as follows:

    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;
 
                                       11
<PAGE>
- - 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 OUR 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 January 1, 1999 on a pro forma basis
assuming we had completed the acquisition of ZMP and the related borrowings
under the new credit facility on January 1, 1999, our new credit facility would
have permitted additional borrowings of up to $21.0 million and all of those
borrowings would have been 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 is subject not only to our performance within our industry, but also 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 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.
 
                                       12
<PAGE>
    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 our senior debt and
the senior debt of 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 us or the guarantors, holders of the New Notes will
participate with trade creditors and all other holders of our subordinated
indebtedness and the subordinated indebtedness of 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, the acquisition of ZMP and the
related borrowings under the new credit facility on January 1, 1999, the New
Notes and the guarantees by our domestic subsidiary would have been subordinated
to $133.0 million of senior debt under our new credit facility. In addition, the
new credit facility would have provided for up to approximately $21.0 million of
additional borrowings. Holdings' guarantee of the New Notes would have been
subordinated to $153.2 million of senior debt consisting of the guarantee of the
new credit facility and the value of the Holdings' pay-in-kind 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, which
consists of Holdings' guarantee of the borrowings under the new credit facility
and the borrowings consisting of the face value of the Holdings' pay-in-kind
notes, in each case, whose holders would be paid before you in the event of a
liquidation.
    
 
    DEPENDENCE ON MAJOR CUSTOMERS--WE RELY 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, which includes 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.
 
                                       13
<PAGE>
    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.
 
    Since we do not have long-term contracts with most of our customers, future
sales of our products are not guaranteed. Even in those cases where we do, such
as 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 us to recover for increases in input prices,
taxes or labor costs. Any such increases without increases in our prices are
likely to have an adverse effect on our business and may affect our ability to
make payments to you under the New Notes.
 
    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 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.
 
                                       14
<PAGE>
    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.
 
   
    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."
 
    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. 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."
 
   
    At September 30, 1998, approximately 30% of our employees were unionized.
Our collective bargaining agreements expire in April 2002 and November 2000.
Although we believe that our relations 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 or
shortage in skilled employees 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 unique component parts that we use to manufacture our components. Because we
maintain a relatively small inventory of raw materials and component parts, our
business could be adversely affected by factors affecting our
 
                                       15
<PAGE>
suppliers, or by increased costs of such raw materials or components if we are
unable to pass along such price increases to our customers. 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 or persons who arrange (as defined under these statutes) for
the disposal or treatment of hazardous materials 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. 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.
 
    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%, 20% and 20% of our sales in fiscal 1998, fiscal 1997 and
fiscal 1996, respectively, were made 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 CURRENT AND 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.
    
 
   
    On April 23, 1999, we acquired ZMP, Inc., the corporate parent of Adams Rite
Aerospace, through a merger. The purchase price for the acquisition was $41
million, subject to post-closing purchase price adjustments. The acquisition was
funded entirely through additional borrowings under the new credit facility. We
intend to pursue additional acquisitions that we believe will present
    
 
                                       16
<PAGE>
   
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. Although we currently have no
binding agreements with respect to any additional acquisitions and we cannot
assure you that we will be able to reach agreement with respect to any
additional 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. In addition, if we are unable to
successfully assimilate the operations, technologies, services and products of
Adams Rite Aerospace with that of our other three divisions or if the
assimilation of Adams Rite Aerospace materially diverts the management's
attention from other business concerns, 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 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 also compete for a limited number of customers.
We believe that our ability to compete depends on product performance, short
lead-time and timely delivery, competitive pricing, responsiveness to our
customers and continued certification under customer quality requirements and
assurance programs. If we do not retain an advantage vis a vis our competitors
in these areas, our business may be adversely affected. 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 are completing a review of our information technology systems and
embedded systems in order to assess our exposure to Year 2000 issues. For
details of this review see "Management's Discussion and Analysis of Financial
Condition and Results of Operation--Impact of Year 2000 Issue."
 
    In the event that Year 2000 problems arise for us, or that our significant
suppliers or customers, including various agencies of the United States
government, do not successfully and timely achieve Year 2000 compliance, we may
have to bear Year 2000 costs and expenses which could have a material adverse
effect on our business.
 
    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.
 
                                       17
<PAGE>
    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 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 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."
    
 
    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.
 
    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 US 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 of our other debts or debts of any guarantor if, among other things, we or
that 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
 
                                       18
<PAGE>
- - was insolvent or rendered insolvent by reason of such incurrence; or
 
- - was engaged in a business or transaction for which our or that 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 us or that guarantor pursuant to the New Notes
or a guarantee could be voided and required to be returned to us or that
guarantor, or to a fund for the benefit of the creditors of us or that
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, we 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.

                                  TRANSACTIONS
 
   
    On April 23, 1999, TransDigm acquired ZMP, Inc., the corporate parent of
Adams Rite Aerospace, Inc., under the terms of an agreement and plan of
reorganization, dated March 31, 1999. The purchase price for the acquisition of
ZMP was $41 million, subject to post-closing purchase price adjustments. The
acquisition of ZMP and the related expenses were funded entirely through
additional borrowings under the New Credit Facility.
    
 
   
    On December 3, 1998, together with the completion of the offering of the Old
Notes by TransDigm, Holdings consummated a recapitalization of Holdings (the
"Recapitalization") under the terms of 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, TransDigm
entered into a credit agreement (as amended, the "New Credit Facility")
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 $8.0 million of which was funded to consummate the
acquisition of ZMP, and a 6-year $62.0 million Tranche A Term Loan Facility (the
"Tranche A Facility") and a 7 1/2-year $62.0 million Tranche B Term Loan
Facility (the "Tranche B Facility"), in each case, $45.0 million of which was
funded to consummate the Recapitalization and $17.0 million of which was funded
to consummate the acquisition of ZMP. 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."
    
 
   
    As part of 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 a payment in the
Recapitalization of $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 Recapitalization, 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, the acquisition of ZMP and the related
borrowings under the New Credit Facility are collectively referred to herein as
the "Transactions."

<PAGE>
                               THE EXCHANGE OFFER
 
PURPOSE AND EFFECT
 
   
    Together with the sale by TransDigm of the Old Notes on December 3, 1998,
TransDigm, Holdings and Marathon (together with Holdings, the "Initial
Guarantors") entered into a registration rights agreement (the "Registration
Rights Agreement"), dated December 3, 1998, with the initial purchasers, which
requires that TransDigm and the Initial 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 TransDigm must cause the Registration Statement with
respect to the exchange offer to be declared effective by May 2, 1999 and
consummate the exchange offer by June 6, 1999.
    
 
   
    Except for exceptions listed below, upon the completion of the exchange
offer, TransDigm'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,
TransDigm 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, holders of Old Notes not tendered will not have any further
registration rights other than as set forth in the paragraphs below, 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
TransDigm, among other things, that:
 
       -  the New Notes acquired pursuant to the exchange offer are being
          obtained in the ordinary course of business of the holder;
 
       -  the holder is not engaging in and does not intend to engage in a
          distribution of the New Notes;
 
       -  the holder does not have an arrangement or understanding with any
          person to participate in the distribution of the New Notes; and
 
       -  the holder is not an "affiliate," as defined under Rule 405 under the
          Securities Act, of TransDigm or the Guarantors.
 
   
    Under certain circumstances specified in the Registration Rights Agreement,
TransDigm 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 "--Procedure for Tendering" and "Registration Rights."
    
 
    Based on an interpretation by the Commission's staff set forth in no-action
letters issued to third parties unrelated to TransDigm, TransDigm believes that,
with the exceptions set forth below, New Notes issued in the exchange offer may
be offered for resale, resold and otherwise transferred by the holder of New
Note without compliance with the registration and prospectus delivery
requirements of the Securities Act, unless the holder:
 
       -  is an "affiliate" of TransDigm or the Guarantors within the meaning of
          Rule 405 under the Securities Act;
 
                                       21
<PAGE>
       -  is a broker-dealer who purchased Old Notes directly from TransDigm for
          resale under Rule 144A or any other available exemption under the
          Securities Act;
 
       -  acquired the New Notes other than in the ordinary course of the
          holder's business; or
 
       -  the holder has an arrangement with any person to engage in the
          distribution of 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.
 
TERMS OF THE EXCHANGE OFFER
 
   
    Upon the terms and subject to the conditions set forth in this prospectus
and in the letter of transmittal, TransDigm 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. TransDigm
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 New Notes will evidence the same debt as the Old Notes and will be
issued under the terms of, and entitled to the benefits of, the Indenture
relating to the Old Notes.
 
   
    As of the date of this prospectus, 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. TransDigm 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 under the Exchange Act.
    
 
    TransDigm shall be deemed to have accepted validly tendered Old Notes when,
as, and if TransDigm 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 TransDigm. If any tendered Old Notes are
not accepted for exchange because of an invalid tender, the occurrence of
certain other events set forth under the heading "--Conditions to the Exchange
Offer" or otherwise, certificates for any such unaccepted Old Notes will be
returned, without expense, to the tendering holder of those Old Notes as
promptly as practicable after         , 1999, unless the exchange offer is
extended.
 
    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 in the
exchange offer. TransDigm will pay all charges and expenses, other than certain
applicable taxes, applicable to 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 TransDigm, in its sole discretion, extends the exchange offer, in
which case the expiration date shall mean the latest
 
                                       22
<PAGE>
date and time to which the exchange offer is extended. In order to extend the
exchange offer, TransDigm 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. TransDigm reserves the right, in its sole discretion, (A) 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
that delay, extension or termination to the Exchange Agent, or (B) to amend the
terms of the exchange offer in any manner. In the event that TransDigm makes a
material or fundamental change to the terms of the exchange offer, TransDigm
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 of the letter of transmittal, have the signatures on the letter of
transmittal 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:
 
       -  certificates for the Old Notes must be received by the Exchange Agent
          along with the letter of transmittal prior to the expiration date;
 
       -  a timely confirmation of a book-entry transfer (a "Book-Entry
          Confirmation") of the Old Notes, if that procedure is available, into
          the Exchange Agent's account at DTC (the "Book-Entry Transfer
          Facility") following the procedure for book-entry transfer described
          below, must be received by the Exchange Agent prior to the expiration
          date; or
 
       -  you 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.
 
    Your tender, if not withdrawn before the expiration date will constitute an
agreement between you and TransDigm 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 YOUR ELECTION AND RISK.
INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT YOU 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 TRANSDIGM. YOU MAY REQUEST YOUR
BROKERS, DEALERS, COMMERCIAL BANKS, TRUST COMPANIES OR NOMINEES TO EFFECT THESE
TRANSACTIONS FOR YOU.
 
    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 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 guarantor institution" within the
meaning of Rule 17Ad-15 under the Exchange Act (an "Eligible Institution")
unless Old Notes tendered pursuant thereto are tendered (A) by a registered
holder who has not completed the box entitled "Special Registration Instruction"
or "Special Delivery Instructions" on the letter of transmittal or (B) 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
 
                                       23
<PAGE>
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 Institution.
 
    If the letter of transmittal is signed by a person other than the registered
holder of any Old Notes listed in the letter of transmittal, 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 TransDigm
of their authority to so act must be submitted with the letter of transmittal
unless waived by TransDigm.
 
    All questions as to the validity, form, eligibility, including time of
receipt, acceptance, and withdrawal of tendered Old Notes will be determined by
TransDigm in its sole discretion, which determination will be final and binding.
TransDigm reserves the absolute right to reject any and all Old Notes not
properly tendered or any Old Notes TransDigm's acceptance of which would, in the
opinion of counsel for TransDigm, be unlawful. TransDigm also reserves the right
to waive any defects, irregularities or conditions of tender as to particular
Old Notes. TransDigm'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
TransDigm shall determine. Although TransDigm intends to notify holders of
defects or irregularities with respect to tenders of Old Notes, neither
TransDigm, the Exchange Agent, nor any other person shall incur any liability
for failure to give that 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, TransDigm 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, you will represent to TransDigm that, among other things:
 
       -  the New Notes acquired in 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;
 
       -  you are not engaging in and do not intend to engage in a distribution
          of the New Notes;
 
       -  you do not have an arrangement or understanding with any person to
          participate in the distribution of such New Notes; and
 
       -  you are not an "affiliate," as defined under Rule 405 of the
          Securities Act, of TransDigm or any of the Guarantors.
 
    In all cases, issuance of New Notes for Old Notes that are accepted for
exchange in 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
 
                                       24

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 or, in the case of Old Notes tendered by book-entry
transfer into the Exchange Agent's account at the Book-Entry Transfer Facility
according to the book-entry transfer procedures described below, those
nonexchanged Old Notes will be credited to an account maintained with that
Book-Entry Transfer Facility, in each case, 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 those 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 those 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
that 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 of the letter of
transmittal, 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 instead 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 Old Notes and the
Old Notes are not immediately available, or time will not permit that 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:
 
       -  the tender is made through an Eligible Institution;
 
       -  prior to the expiration date, the Exchange Agent receives from that
          Eligible Institution a properly completed and duly executed letter of
          transmittal or a facsimile of duly executed letter of transmittal and
          notice of guaranteed delivery, substantially in the form provided by
          TransDigm, by telegram, telex, fax transmission, mail or hand
          delivery, setting forth the name and address of the holder of Old
          Notes and the amount of Old Notes tendered and stating that the tender
          is being made by guaranteed delivery 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
 
                                       25
<PAGE>
       -  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:
 
       -  specify the name of the person having deposited the Old Notes to be
          withdrawn (the "Depositor");
 
       -  identify the Old Notes to be withdrawn, including the certificate
          number or numbers and principal amount of such Old Notes;
 
       -  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
 
       -  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, eligibility and time of receipt of
such notices will be determined by TransDigm, 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 of those Old Notes without cost to
that 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, TransDigm 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 those Old Notes for exchange or the exchange of the New
Notes for those Old Notes, TransDigm 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 TransDigm and may be
asserted by TransDigm regardless of the circumstances giving rise to any such
condition or may be waived by TransDigm in whole or in part at any time and from
time to time in its sole discretion. The failure by TransDigm at any time to
exercise any of the foregoing rights shall not be deemed a waiver of any of
those rights and each of those rights shall be deemed an ongoing right which may
be asserted at any time and from time to time.
 
    In addition, TransDigm will not accept for exchange any Old Notes tendered,
and no New Notes will be issued in exchange for those 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. In any of those events
TransDigm
 
                                       26
<PAGE>
is required to use every reasonable effort to obtain the withdrawal of any stop
order at the earliest possible time.

soliciting acceptances of the exchange offer. The principal solicitation is
being made by mail; however, additional solicitations may be made in person or

to be incurred in connection with the exchange offer will be paid by TransDigm
and will include 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 with that tender or exchange, except that
holders who instruct TransDigm to register New Notes in the name of, or request
that Old Notes not tendered or not accepted in the exchange offer be returned
to, a person other than the registered tendering holder will be responsible for
the payment of any applicable transfer tax on those Old Notes.

    TransDigm 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, TransDigm 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.

             UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL INFORMATION
 
   
    The following pro forma consolidated financial information of TransDigm 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 and the thirteen weeks ended January 1, 1999 and as at
January 1, 1999. The pro forma consolidated statements of operations give effect
to each of the Transactions as if they had been consummated at the beginning of
each respective period. The pro forma consolidated balance sheet gives effect to
the acquisition of ZMP and the related borrowings under the New Credit Facility
as if they had occurred as of the balance sheet date. 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 Transactions been consummated on
the respective dates indicated and do not purport to indicate results of
operations for any future period. You should read the pro forma consolidated
financial statements together with 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.
    
 
   
    As a result of the consummation of the Recapitalization, Odyssey and its
co-investors acquired 73.7% of Holdings common stock on a fully diluted basis
and certain continuing equity holders of Holdings retained approximately 26.3%
of the common stock. Accordingly, the Recapitalization was accounted for as a
recapitalization and had no impact on the historical basis of TransDigm's and
Holdings' assets and liabilities. The pro forma adjustments were applied to the
respective historical consolidated financial statements to reflect and account
for the Recapitalization as a recapitalization.
    
 
   
    The acquisition of ZMP has been accounted for as a purchase. The purchase
price consideration of $41 million in cash and $1 million of costs associated
with the acquisition was funded entirely through additional borrowings under the
New Credit Facility. The purchase price has been allocated to the assets
acquired and liabilities assumed of ZMP and its wholly-owned subsidiary, Adams
Rite Aerospace, based on a preliminary analysis of their fair values.
    
 
   
    One-time merger charges of approximately $39.6 million and $0.2 million
($28.8 million and $0.1 million after tax), incurred in connection with, or due
to, the Recapitalization and the acquisition of ZMP, respectively, were
recorded, in each case, in the first quarter of fiscal 1999, as follows:

                SELECTED HISTORICAL CONSOLIDATED FINANCIAL DATA
 
   
    The following table sets forth selected historical consolidated financial
information of Holdings. 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. The selected
historical consolidated financial data as of and for the thirteen weeks ended
January 1, 1999 and December 26, 1997 has been derived from Holdings' unaudited
consolidated financial statements for those periods, which, in the opinion of
management, include all adjustments, consisting only of normal recurring
adjustments, necessary for a fair presentation of the results of operations,
financial position, and cash flows. The results for the thirteen weeks ended
January 1, 1999 are not necessarily indicative of results that may be expected
for the entire year. Separate financial information for TransDigm is not
presented since the New Notes will be guaranteed by Holdings and all direct and
indirect domestic subsidiaries of TransDigm, and since Holdings has no
operations or assets separate from its investment in TransDigm.
    
 
    The Marathon Acquisition was completed 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.
 
   
    You should read the following table together with the "Management's
Discussion and Analysis of Financial Condition and Results of Operations"
section and the Consolidated Historical Financial Statements and the notes
thereto included elsewhere in this prospectus.

(1) 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.
 
(2) All of the interest expense reported for fiscal 1994 through 1998 represents
    interest expense of TransDigm. Holdings had no interest expense prior to the
    Recapitalization. After the Recapitalization, Holdings has incurred interest
    expense relating to the Holdings PIK Notes and Holdings has no other
    interest expense. TransDigm is not an obligor or a guarantor under the
    Holdings PIK Notes. Interest expense for the Holdings PIK Notes for the
    thirteen weeks ended January 1, 1999 was $200.
 
(3) EBITDA represents earnings before interest, taxes, depreciation,
    amortization, warrant put value adjustment and extraordinary items. EBITDA
    is presented because management believes it is frequently used by securities
    analysts, investors and other interested parties in the evaluation of
    companies in Holdings' industry. However, other companies in Holdings'
    industry may calculate EBITDA differently than Holdings does. EBITDA is not
    a measurement of financial performance under generally accepted accounting
    principles and should not be considered as an alternative to cash flow from
    operating activities, as a measure of liquidity or an alternative to net
    income as indicators of Holdings' operating performance or any other
    measures of performance derived in accordance with generally accepted
    accounting principles. See Holdings' consolidated Statements of Cash Flows
    included in Holdings' consolidated financial statements.

    EBITDA, As Defined, is presented herein to provide additional information
    with respect to the ability of Holdings to satisfy its debt service, capital
    expenditure and working capital requirements and because certain types of
    covenants in TransDigm's and Holdings' borrowing arrangements are tied to
    similar measures. While EBITDA-based measures are frequently used as
    measures of operations and the ability to meet debt service requirements,
    they are not necessarily comparable to other similarly titled captions of
    other companies due to differences in methods of calculation.
 
(5) 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, $127 and $32,390 for fiscal
    1994, fiscal 1995 and the thirteen weeks ended January 1, 1999,
    respectively.

FISCAL YEAR ENDS ON SEPTEMBER 30 OF THE YEARS INDICATED.
 
OVERVIEW
 
    TransDigm is a leading supplier of highly engineered aircraft components for
use on nearly all commercial and military aircraft. TransDigm 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 TransDigm'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 TransDigm and others. TransDigm generates most of its EBITDA, As Defined
from sales of replacement parts in the aftermarket, including to the airlines.
This is because most of TransDigm's OEM sales are on an exclusive sole source
basis; therefore, in most cases, TransDigm 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.
 
    TransDigm 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 TransDigm'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 TransDigm's net sales during
fiscal 1998 and the thirteen weeks ended January 1, 1999 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 TransDigm'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 TransDigm. To
ensure a competitive cost structure, TransDigm consolidated the Adel Fasteners
and Wiggins Connectors divisions into AdelWiggins and the AeroProducts and
Controlex divisions into AeroControlex and, in fiscal 1994, consolidated
TransDigm'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. As a result of the
acquisition of ZMP, TransDigm acquired four additional major product lines of
Adams Rite Aerospace. Management
    
 
                                       42
<PAGE>
   
intends to reorganize the business along 15 major product lines to incorporate
the four major product lines of Adams Rite Aerospace.
    
 
    TransDigm's historical financial results are also affected by the
acquisition of Marathon on August 8, 1997. Marathon's operations were
consolidated with those of TransDigm as of the acquisition date.
 
   
    The Recapitalization was recorded as a recapitalization for accounting
purposes. As a result of the Recapitalization, including the financing and the
application of the proceeds thereof, TransDigm 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 TransDigm'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 for the thirteen weeks ended January 1, 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 TransDigm's liquidity, ongoing operations or
market position. For a discussion of the consequences of the incurrence of
indebtedness as a result of the Transactions, see the heading "--Liquidity and
Capital Resources" in this section.
    
 
   
    On April 23, 1999, TransDigm acquired ZMP, the corporate parent of Adams
Rite Aerospace. Adams Rite Aerospace is a well established supplier of highly
engineered aircraft components that will complement the businesses of
AdelWiggins, AeroControlex and Marathon. Through the acquisition of ZMP,
TransDigm acquired four additional major product lines of Adams Rite Aerospace
consisting of mechanical hardware, fluid control products, electromechanical
control products and oxygen systems related products. For its fiscal 1998, Adams
Rite Aerospace generated net sales, operating income and EBITDA, As Defined, of
$34.2 million, $3.6 million and $5.4 million, respectively.

(1) Together with the formation of TransDigm on September 30, 1993, TransDigm
    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. If no transaction constituting a triggering
    event was consummated prior to July 31, 1999, warrant holders had the right
    to exercise a put option requiring TransDigm to repurchase all of the
    warrants at their then appraised fair market value. 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
 
THIRTEEN WEEKS ENDED JANUARY 1, 1999 COMPARED WITH THIRTEEN WEEKS ENDED DECEMBER
  26, 1997
 
- - NET SALES. Net sales increased by $2.1 million, or 8.0%, to $28.2 million for
  the thirteen weeks ended January 1, 1999 from $26.1 million for the thirteen
  weeks ended December 26, 1997. Substantially all of the increase was due to
  higher aftermarket sales, principally for large commercial transport aircraft,
  reflecting TransDigm's continued efforts to increase sales in this area
  because of the larger gross margins that are generally realized from such
  sales.
 
- - GROSS PROFIT. Gross profit (net sales less cost of sales) increased by $1.9
  million, or 16.7%, to $13.3 million for the thirteen weeks ended January 1,
  1999 from $11.4 million for the thirteen weeks ended December 26, 1997. This
  improvement in gross profits was principally the result of the higher
  aftermarket sales discussed above and the larger gross margins that are
  associated with such sales. Gross profit for the thirteen weeks ended December
  26, 1997 includes the effect of a non-cash charge of $0.3 million due to a
  purchase accounting adjustment to inventory associated with the acquisition of
  Marathon. Gross profit also increased as a percentage of net sales from 43.7%
  for the thirteen weeks ended December 26, 1997 to 47.0% for the thirteen weeks
  ended January 1, 1999 due to the non-cash charge from the Marathon inventory
  purchase accounting adjustment and the increase in aftermarket sales.
 
- - SELLING AND ADMINISTRATIVE. Selling and administrative expense was unchanged
  at $2.7 million for the thirteen weeks ended January 1, 1999 and December 26,
  1997. Selling and administrative expenses as a percentage of net sales
  decreased from 10.2% for the thirteen weeks ended December 26, 1997 to 9.5%
  for the thirteen weeks ended January 1, 1999 due to the increase in sales
  referred to above and continued programs to manage expenses.
 
- - AMORTIZATION OF INTANGIBLES. Amortization of intangibles was unchanged at $0.6
  million for the thirteen weeks ended January 1, 1999 and December 26, 1997.
 
- - RESEARCH AND DEVELOPMENT. Research and development expense increased $.1
  million, or 33.3%, to $.4 million for the quarter ended January 1, 1999 from
  $.3 million for the comparable quarter last year. This increase was primarily
  attributable to continued new product development at each of
  AdelWiggins, AeroControlex and Marathon. Research and development expense as a
  percentage of net sales remained relatively constant at 1.6% for the thirteen
  weeks ended January 1, 1999 and 1.3% for the thirteen weeks ended December 26,
  1997.
 
- - MERGER EXPENSES. Merger costs totaling $39.6 million were incurred during the
  thirteen weeks ended January 1, 1999 in connection with the Merger and
  Recapitalization. The nature of the merger-related charges is detailed below:

  thirteen weeks ended December 26, 1997 to a loss of $30.1 million for the
  thirteen weeks ended January 1, 1999 due to the merger expenses discussed
  above. Operating income, excluding merger-related expenses, increased by $1.7
  million, or 21.8%. As a percentage of net sales, operating income before
  merger-related
 
                                       44
<PAGE>
  expenses increased to 33.6% for the thirteen weeks ended January 1, 1999 from
  29.7% for the thirteen weeks ended December 26, 1997. This increase was
  primarily attributable to the increase in sales volume and gross profits
  referred to above.
 
- - INTEREST EXPENSE. Interest expense increased by $1.2 million, or 109%, to $2.3
  million for the thirteen weeks ended January 1, 1999 from $1.1 million for the
  thirteen weeks ended December 26, 1997 as a result of the increase in the
  average level of outstanding borrowings in connection with the
  Recapitalization.
 
- - INCOME TAXES. Income tax expense (benefit) as a percentage of income (loss)
  before income taxes was (23.3)% for the thirteen weeks ended January 1, 1999
  compared to 38.6% thirteen weeks ended December 26, 1997. The tax benefit
  recorded for the thirteen weeks ended January 1, 1999 was significantly
  impacted by the non-deductible expenses incurred in connection with the
  Recapitalization.
 
- - NET INCOME (LOSS). TransDigm incurred a net loss of $24.8 million for the
  thirteen weeks ended January 1, 1999 compared to net income of $4.1 million
  for the thirteen weeks ended December 26, 1997 primarily as a result of the
  factors referred to above.
 
FISCAL YEAR ENDED SEPTEMBER 30, 1998 COMPARED WITH FISCAL YEAR ENDED SEPTEMBER
  30, 1997
 
- - NET SALES. Net sales increased by $32.8 million, or 42%, to $110.9 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. New business initiatives along with continued strength in airline
  traffic and airline capital spending resulted in a $7.4 million increase in
  aftermarket sales, principally for large commercial transport aircraft, and a
  $5.9 million increase in sales to OEMs.
 
- - GROSS PROFIT. Gross profit (net sales less cost of sales) increased by $22.6
  million, or 78.2%, to $51.5 million for fiscal 1998 from $28.8 million for
  fiscal 1997. Approximately $9.5 million of this increase was attributable to
  the acquisition of Marathon, including a $0.4 million reduction in the charge
  to Marathon's cost of sales resulting from the write-up of Marathon's
  inventory in place at the time of the acquisition. In addition, the higher
  sales discussed above resulted in $7.8 million of additional gross profit from
  aftermarket sales, principally for large commercial transport aircraft, and
  $5.3 million from sales to OEMs. Gross profit increased as a percentage of net
  sales from 36.9% in the 1997 period to 46.4% in fiscal 1998. Approximately,
  3.8% of this increase was attributable to the acquisition of Marathon and the
  remainder due to the higher sales discussed above.
 
- - 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 partially offset by reduction in bad debt and environmental
  expenses of $0.3 million each. 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. The increase in the amortization of intangibles resulted from
  $0.5 million of additional goodwill amortization relating to the acquisition
  of Marathon offset by a $0.2 million reduction in the 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.
 
                                       45
<PAGE>
- - 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. The $2.1 increase
  in interest expense resulting from the additional borrowings made in
  connection with acquisition of Marathon was more than offset by a $2.4
  decrease in interest expense caused by the refinancing of TransDigm's
  subordinated notes and a general decline in interest rates.
 
- - 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 a result of the
  factors referred to above and an extraordinary loss in 1997 of $1.5 million
  partially offset by a $1.7 million increase in the warrant put value
  adjustment during fiscal 1998.
 
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. Approximately $3.0 million
  of this increase was attributable to the acquisition of Marathon. New business
  initiatives along with an industry-wide increase in demand resulted in a $7.2
  million increase in aftermarket sales, principally for large commercial
  transport aircraft, and a $5.1 million increase in sales to OEMs.
 
- - GROSS PROFIT. Gross profit (net sales less cost of sales) increased by $7.9
  million, or 37.6%, to $28.9 million for fiscal 1997 from $21.0 million for
  fiscal 1996. Approximately $0.5 million of this increase was attributable to
  the acquisition of Marathon. The higher sales discussed above resulted in $5.2
  million of additional gross profit from aftermarket sales, principally for
  large commercial transport aircraft, and $2.2 million from sales to OEMs.
  Gross profit also increased as a percentage of net sales from 33.4% in the
  1996 period to 36.9% in fiscal 1997. This increase was primarily attributable
  to the higher sales discussed above offset by an approximate 1% decline in
  gross margins due to higher cost of sales resulting from the write-up of
  Marathon's inventory in place at the time of the acquisition.
 
- - 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. Approximately $0.4 million of this increase was due to the
  acquisition of Marathon, $0.3 million resulted from the relocation of
  TransDigm's corporate headquarters and the remainder was caused by the
  increase in sales volume which generated larger commission expenses. 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
 
                                       46
<PAGE>
  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. Foreign sales corporation earnings in
  fiscal 1997 decreased the effective rate by 2.7%; however, higher
  non-deductible expenses, including the amortization of goodwill recognized in
  connection with the Marathon acquisition, increased the effective rate by
  0.2%.
 
- - 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 a result of the
  factors referred to above partially offset by a $2.6 million increase in the
  warrant put value adjustment during 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
 
    TransDigm 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. TransDigm used approximately $32.7
million of cash in operating activities during the thirteen weeks ended January
1, 1999 compared to approximately $6.5 million generated during the thirteen
weeks ended December 26, 1997. Such decrease in operating cash flows is due to
the one-time merger expenses of $39.6 million partially offset by improved
operating results.
 
    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.
TransDigm'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. Cash
used in investing activities was approximately $0.7 million during the thirteen
weeks ended January 1, 1999 compared to approximately $0.1 million generated
during the thirteen weeks ended December 26, 1997. The change in investing cash
flows is primarily due to post-closing purchase price adjustment of
approximately $0.7 million received during the thirteen weeks ended December 26,
1997 as a result of the Marathon acquisition.
 
    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. Cash provided by financing activities during the
thirteen weeks ended January 1, 1999 was approximately $16.1 million compared to
approximately $20 thousand used during the thirteen weeks ended December 26,
1997. This change in financing cash flows was due
 
                                       47
<PAGE>
to incurrence and refinancing of substantial indebtedness as a result of the
Recapitalization and Merger.
 
   
    As a result of the Recapitalization and the acquisition of ZMP, the Company
incurred substantial indebtedness and refinanced certain other indebtedness
including all borrowings under the prior credit facility. See the
"Capitalization" section. As of January 1, 1999 on a pro forma basis after
giving effect to the acquisition of ZMP and the related borrowings under New
Credit Facility as if they had occurred on January 1, 1999, Holdings would have
had indebtedness consisting of $20.2 million in Holdings PIK Notes and TransDigm
would have had indebtedness consisting of (1) $125.0 million in principal amount
of the Old Notes and (2) $133.0 million of borrowings under the New Credit
Facility, which would have consisted of $9.0 million under a $30.0 million
Revolving Credit Facility, a $62.0 million term loan under the Tranche A
Facility and a $62.0 million term loan under the Tranche B Facility.
    
 
   
    The interest rate for the New Credit Facility is, at TransDigm's option,
either (A) a floating rate equal to the Base Rate (as defined in this Prospectus
under the heading "Description of Other Indebtedness--The Company's New Credit
Facility") plus the Applicable Margin (as defined in this paragraph), or (B) the
Eurodollar Rate (as defined in this Prospectus under the heading "Description of
Other Indebtedness--The Company's New Credit Facility") for fixed periods of
one, two, three, or six months, plus the Applicable Margin. The "Applicable
Margin" means the percentage per year equal to (1) in the case of Tranche A
Facility and Revolving Credit Facility, (A) bearing an interest rate determined
by the Base Rate, 2.50% through February 16, 1999 and 2.25%, 2.00%, 1.75% or
1.50% thereafter depending on Holdings' ability to achieve the respective debt
coverage ratio specified in the New Credit Facility, as amended, and (B) bearing
an interest rate determined by the Eurodollar Rate, 3.50% through February 16,
1999 and 3.25%, 3.00%, 2.75% or 2.50% thereafter depending on Holdings' ability
to achieve the respective debt coverage ratio specified in the New Credit
Facility, as amended, and (2) in the case of Tranche B Facility (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%. 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 that are 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 TransDigm 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.
 
   
    TransDigm's primary cash needs will consist of capital expenditures and debt
service. TransDigm 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, $5.1 million, $0.6 million and $0.7 million in fiscal 1996, fiscal
1997, fiscal 1998, the thirteen weeks ended December 26, 1997 and the thirteen
weeks ended January 1, 1999, respectively. TransDigm estimates that capital
expenditures, excluding those of Adams Rite Aerospace, will total approximately
$5.6 million in fiscal 1999.
    
 
                                       48
<PAGE>
    TransDigm intends to pursue additional acquisitions that present
opportunities to realize significant synergies, operating expense economies or
overhead cost savings or to increase TransDigm's market position. TransDigm
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. TransDigm's
acquisition strategy may require substantial capital, and no assurance can be
given that TransDigm will be able to raise any necessary funds on terms
acceptable to TransDigm or at all. If TransDigm incurs additional debt to
finance acquisitions, its total interest expense will increase. See "Risk
Factors--Risks Related to Potential Future Acquisitions."
 
    TransDigm'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 TransDigm's
future liquidity needs for at least the next few years. TransDigm 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 TransDigm'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 TransDigm 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 TransDigm 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 January
1, 1999, TransDigm estimated its sales order backlog at $45.9 million compared
to an estimated $43.7 million as of December 26, 1997. The majority of the
purchase orders outstanding as of January 1, 1999 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 TransDigm's receipt of purchase orders and the speed with which those
orders are filled. Accordingly TransDigm's backlog as of January 1, 1999 is not
necessarily indicative of actual shipments or sales for any future period, and
period-to-period comparisons may not be meaningful.
 
FOREIGN OPERATIONS
 
    TransDigm manufactures virtually all of its products in the United States.
However, a significant portion of TransDigm's current sales are conducted
abroad. Approximately 16%, 20%, and 20% of TransDigm's net sales in fiscal 1998,
fiscal 1997, and fiscal 1996, respectively, were made directly 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. 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 TransDigm 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 TransDigm's operations and growth
strategy.
 
                                       49
<PAGE>
INFLATION
 
    Many of TransDigm'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 TransDigm'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 equity
section of a statement of financial position. TransDigm adopted this standard
during the first quarter of 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. TransDigm will adopt this standard for its fiscal 1999
year-end financial statements.
 
    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 in its
year-end financial statements 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. TransDigm 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. TransDigm will adopt this
standard during fiscal 2000.
 
    While management has not completed its analysis of these new accounting
standards contained in SFAS No. 131, SFAS No. 132 and SFAS No. 133, the adoption
of these standards is not expected to have a material effect on TransDigm's
financial statements.
 
IMPACT OF YEAR 2000 ISSUE
 
   
    TransDigm has completed a review of its information technology systems in
the Waco, Texas site and is completing a review of its information technology
systems in the Los Angeles, California site and the Cleveland, Ohio site.
TransDigm is also completing a review of its embedded systems at each of the
three sites, in order to assess its exposure to Year 2000 issues. These reviews,
including testing and verification, will be completed internally. Management
anticipates that these reviews, including testing and verification will be
completed by June 1999. Prior to the acquisition of ZMP, ZMP represented to
TransDigm that the review of Adams Rite Aerospace's information technology
systems and embedded systems have been completed and that it believes the plan
to make those systems Year 2000 compliant can be fully implemented by December
1999. However, TransDigm has not initiated its independent review of Adams Rite
Aerospace's information technology systems or embedded systems. Although
management believes that any repairs necessary to make their embedded systems
Year 2000 compliant
    
 
                                       50
<PAGE>
can be completed internally, until TransDigm has completed its review, testing
and verification of its embedded systems, TransDigm will not be in a position to
assess the extent of repairs that will be required or the parts that will need
to be replaced in order to make its embedded systems Year 2000 compliant.
TransDigm purchased all of its computer software from third party vendors and is
relying on those vendors to make their software Year 2000 compliant. Except for
the vendor of its e-mail system, those vendors have provided TransDigm with
third party certifications that their systems are Year 2000 compliant.
 
   
    TransDigm has distributed questionnaires to assess the Year 2000 compliance
of its suppliers and customers; including various agencies of the United States
government. However, TransDigm has not currently gathered sufficient data to
determine to what extent those suppliers and customers are Year 2000 compliant.
Prior to the acquisition of ZMP, ZMP represented to TransDigm that it has
received confirmation from the material suppliers and customers of Adams Rite
Aerospace of their respective Year 2000 compliance.
    
 
   
    In the event that Year 2000 problems arise within TransDigm or that its
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 its receiving orders and collecting payments,
leading to a temporary loss of revenue. TransDigm has incurred $180,000 in costs
associated with Year 2000 compliance and, excluding Adams Rite Aerospace,
anticipates incurring $150,000 of additional costs in the future. Because
TransDigm has not independently reviewed the information technology systems and
the embedded systems of Adams Rite Aerospace, management does not currently have
adequate data to estimate the additional cost that may have to be incurred by
TransDigm in order to make Adams Rite Aerospace's systems Year 2000 compliant.
However, since the anticipated additional cost reflects the cost of the review,
testing, verification and repair to be completed internally, TransDigm has not
allocated such cost between its embedded systems and its information technology
systems. TransDigm may, however, have to bear further Year 2000 costs and
expenses which could have a material adverse effect on its business.
    
 
    TransDigm has no formal contingency plan in the event Year 2000 problems
arise with respect to its information technology systems; however, TransDigm'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. In the event that Year 2000
problems arise within our embedded systems, TransDigm intends to employ their
existing subcontractor machinists to manufacture the affected components.
 
QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK
 
   
    All of TransDigm's outstanding indebtedness at September 30, 1998 was repaid
in connection with the Merger and Recapitalization. At January 1, 1999,
TransDigm is subject to interest rate risk with respect to borrowings under its
New Credit Facility as the interest rates on such borrowings vary with market
conditions and, thus, the amount of outstanding borrowings approximates the fair
value of the indebtedness. On a historical basis, the weighted average interest
rate on the $91.0 million of borrowings outstanding under the New Credit
Facility at January 1, 1999 was 8.75%. Also outstanding at January 1, 1999 was
$125.0 million of TransDigm indebtedness in the form of the Old Notes and $20.0
million of Holdings PIK Notes. The interest rates on both of these borrowings
are fixed at 10 3/8% and 12% per year, respectively. Although management
believes that the fair value of these debt obligations approximates their
outstanding balance at January 1, 1999, the effect of a hypothetical one
percentage point decrease in interest rates would increase the estimated fair
value of the borrowings by $13.2 million and $2.4 million, respectively.
    
 
   
    The acquisition of ZMP, including all of its outstanding common stock, on
April 23, 1999 and the related expenses were funded entirely through $42 million
of additional borrowings under the New Credit Facility. The weighted average
interest rate on all borrowings outstanding under the New Credit Facility on
April 23, 1999 was 8.50%. The effect of a hypothetical one percentage point
decrease in interest rates would increase the estimated fair value of the
borrowings outstanding under the New Credit Facility on April 23, 1999 by
approximately $6 million.

                                    BUSINESS
 
THE COMPANY
 
   
    TransDigm is a leading supplier of highly engineered aircraft components for
use on nearly all commercial and military aircraft. TransDigm sells its products
to commercial airlines, aircraft maintenance facilities, aircraft OEMs and to
various agencies of the United States government. TransDigm generates most of
its EBITDA, As Defined, from sales of replacement parts in the aftermarket
including sales to airlines. This is because most of TransDigm's OEM sales are
on an exclusive sole source basis; therefore, in most cases, TransDigm 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
TransDigm 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 on
a pro forma basis as if the Transactions had occurred on October 1, 1997,
TransDigm would have generated net sales, operating income and EBITDA, As
Defined, of $145.0 million, $39.3 million and $49.0 million, respectively. For
the thirteen weeks ended January 1, 1999 on a pro forma basis as if the
Transactions had occurred on October 1, 1998, TransDigm would have generated net
sales, operating income and EBITDA, As Defined, of $37.9 million, $10.3 million
and $12.8 million, respectively.
    
 
    TransDigm differentiates itself based on its engineering and manufacturing
capabilities, and typically will not bid on non-proprietary "build to print"
business. TransDigm has developed strong product brand names within the airline
industry and a reputation for high quality, reliability and customer service.
TransDigm focuses on developing highly customized products to solve specific
problems of aircraft operators and manufacturers. Management estimates that over
80% of the TransDigm's products are of proprietary design. TransDigm 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 Transdigm's revenues, aftermarket sales typically carry a
substantially higher gross margin than sales to OEMs.
 
   
    TransDigm is comprised of four business units: (1) AdelWiggins, (2)
AeroControlex, (3) Marathon, and (4) Adams Rite Aerospace, 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.
Adams Rite Aerospace manufactures mechanical hardware, fluid controls, lavatory
hardware, electromechanical controls and oxygen systems related products.
Marathon manufactures nickel cadmium batteries and static inverters. Marathon
and ZMP, the corporate parent of Adams Rite Aerospace, were acquired in August
1997 and April 1999, respectively 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, TransDigm 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. TransDigm competes in niche individual aircraft component markets
that it estimates range in size from $10 million to $100 million in annual
revenues. TransDigm 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
 
                                       52
<PAGE>
and development reduces the risk of new entrants. Management believes
TransDigm's 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.
 
    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, which consists 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 (1) demand for air travel, (2) aircraft operator
profitability, (3) fleet age, (4) regulatory mandates such as noise reduction,
and (5) 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.
 
                                       53
<PAGE>
- - 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 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
 
    TransDigm believes that its key competitive strengths are:
 
- - LARGE INSTALLED PRODUCT BASE AND RECURRING REVENUE STREAM. Management believes
  that approximately 70% of TransDigm's sales are derived from parts for which
  it has achieved sole source designation and approximately 80% of TransDigm's
  products are of proprietary design. As a result, TransDigm has a large and
  growing installed base of products on large commercial transport and regional,
  business and military platforms. This installed base affords TransDigm 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 TransDigm'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. TransDigm 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.
  TransDigm 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
  TransDigm 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. TransDigm'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, TransDigm 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 and the thirteen weeks
  ended January 1, 1999.
 
- - LEADING POSITIONS IN NICHE MARKETS. With over 40 years of experience in most
  of its product lines, TransDigm 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.
 
                                       54
<PAGE>
  For example, TransDigm 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
  TransDigm was created in 1993, management has successfully integrated four
  distinct operating divisions and formed AdelWiggins and AeroControlex. Most
  recently management has successfully integrated Marathon into TransDigm. 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. TransDigm will continue to focus on
  marketing and manufacturing highly engineered products to customers that place
  a premium on TransDigm capabilities. TransDigm has been effective in
  communicating to aircraft operators the value of TransDigm's products in terms
  of cost savings generated by their greater reliability and performance and
  reduced maintenance requirements. TransDigm's reputation for quality and sole
  supplier status for many parts has allowed it to achieve substantial gross
  margins on its aftermarket products. TransDigm 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. TransDigm has been particularly effective in creating aftermarket
  opportunities by developing superior products to retrofit aircraft already in
  service. New business has contributed significantly to TransDigm's 14%
  compound annual net sales growth rate, excluding Marathon's net sales growth,
  since fiscal 1994, which TransDigm believes is well in excess of the industry
  average growth rate during the same period. TransDigm 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 TransDigm to significantly increase sales without material increases
  in headcount.
 
   
- - PURSUE STRATEGIC ACQUISITIONS. TransDigm 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.
  TransDigm believes the industry is experiencing consolidation due to customer
  requirements, inherent economies of scale and technological advancements that
  favor more sophisticated competitors. TransDigm completed the Marathon
  acquisition and the acquisition of ZMP in August 1997 and April 1999,
  respectively. TransDigm 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 four business units: Adelwiggins, AeroControlex, Marathon and
Adams Rite Aerospace. 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 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 in 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.
    
 
   
    Adams Rite Aerospace, which is located in Fullerton, CA and had 253
employees at April 24, 1998, was acquired in April 1999 as a strategic addition
to TransDigm's other three business lines. Adams Rite Aerospace is a leading
manufacturer of mechanical hardware, fluid controls, lavatory hardware,
electromechanical controls and oxygen systems related products and sells its
products to substantially the same customer base, primarily on a sole source
basis, as that of TransDigm's other three business lines.
    
 
PRODUCTS
 
   
    TransDigm's products are found on virtually all types of aircraft, and
TransDigm supplies components to all major domestic and international airlines.
Management estimates that over 80% of TransDigm's products are of proprietary
design and approximately 70% of TransDigm's sales are derived from parts for
which it has achieved sole source designation. TransDigm's products are grouped
into fifteen major product lines, each of which is profitable and is operated as
a semiautonomous business unit.
    
 
    Much of TransDigm's recent success has been due to its identification and
development of new products for sale in the commercial aftermarket. TransDigm
works closely with customers to identify their unmet needs, such as a component
that fails to meet performance expectations or that requires excessive
maintenance. TransDigm 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 TransDigm
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
TransDigm's sales for fiscal 1998, which constitute five of TransDigm's fifteen
major product lines: (A) flexible tube connectors, (B) special connectors, (C)
Adel clamps, (D) Wiggins service systems and (E) 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
    
 
                                       56
<PAGE>
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.
 
    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, TransDigm 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 TransDigm 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 TransDigm's sales for fiscal 1998, which constitute three of TransDigm's
fifteen major product lines: (A) mechanical controls, (B) pumps and (C) 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 TransDigm 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 manufactures over 5,000 SKUs, representing 21% of
TransDigm's sales for fiscal 1998, which constitute three of TransDigm's fifteen
major product lines: (A) vented cell nickel-cadmium batteries, (B) static
inverters and (C) 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
    
 
                                       57
<PAGE>
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.
 
   
    ADAMS RITE AEROSPACE.  Adams Rite Aerospace manufactures over 6,000 SKUs,
which constitute four of TransDigm's fifteen major product lines: (A) mechanical
hardware, (B) fluid control products, (C) electromechanical control products and
(D) oxygen systems related products. Mechanical hardware include hardware
installed inside the aircraft, such as overhead stowage bin latches, lavatory
indicator and door latches, seat control cables and decompression latches, and
hardware installed outside of the aircraft, such as door bolting systems. Fluid
control products include various aircraft water system components, such as
spigots, soap dispensers and water shut-off valves as well as entire
self-contained water systems. Electromechanical control products include
throttle quadrants, control wheels, electric strikes, speed brake controls and a
variety of handle grips. Oxygen systems related products include oxygen
cylinders, masks, reducers and control panels.
    
 
SALES AND MARKETING
 
    Consistent with TransDigm's overall strategy, TransDigm'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.
 
   
    TransDigm has structured AdelWiggins', AeroControlex's and Marathon's sales
efforts along their collective eleven major product lines, assigning a Product
Line Manager to each line. Management anticipates that Adams Rite Aerospace's
sales efforts will be structured in a similar fashion. 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 TransDigm'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. TransDigm's largest distributor is Aviall, which
provides logistic services to the commercial airlines.
 
MANUFACTURING AND ENGINEERING
 
   
    TransDigm maintains four manufacturing facilities. Each facility serves its
respective operating group, and comprises manufacturing, distribution and
engineering as well as corporate functions,
    
 
                                       58
<PAGE>
   
including management, sales and finance. The AdelWiggins, AeroControlex,
Marathon and Adams Rite Aerospace facilities encompass approximately 105,000,
44,000, 150,000 and 100,000 square feet of manufacturing space in Los Angeles,
California, Cleveland, Ohio, Waco, Texas and Fullerton, California,
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 TransDigm'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. TransDigm 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 TransDigm's operating groups attempts to differentiate itself from
its competitors by producing highly engineered products at a low cost.
TransDigm'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 TransDigm's customers
tolerance and quality requirements.
 
    TransDigm uses sophisticated equipment and procedures to ensure the quality
of its products and to comply with military specifications and FAA and OEM
certification requirements. TransDigm 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 TransDigm's manufacturing facilities.
 
CUSTOMERS
 
    TransDigm's customers include (A) commercial airlines, including national
and regional airlines, particularly for aftermarket MRO components, (B) large
commercial transport and regional and business aircraft OEMs, (C) various
agencies of the United States' government, including the United States military,
and (D) various other industrial customers. TransDigm's three largest customers
for fiscal 1998, were Aviall, a distributor of aftermarket parts to airlines
throughout the world, Boeing which includes, McDonnell Douglas, and various
agencies of the United States' government, which accounted for approximately
20%, 14% and 9%, respectively, of TransDigm's net sales in fiscal 1998.
TransDigm's top ten customers accounted for approximately 61% of TransDigm's net
sales for fiscal 1998.
 
    TransDigm has strong customer relationships with virtually all important
large commercial transport, general aviation and military OEMs. The demand for
TransDigm's aftermarket parts and services is related to TransDigm'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 TransDigm's business is executed under
long-term agreements with customers which encompass many products under a common
agreement. See "Risk Factors-- Customer Contracts." TransDigm is also a leading
supplier of components used on United States' designed military aircraft.
TransDigm's products are used on a variety of fighter aircraft, and helicopters.
Military aircraft using TransDigm's products include the Lockheed F-15 and F-16,
the E2C (Hawkeye) and Blackhawk and Apache helicopters.

COMPETITION
 
    TransDigm competes with a number of established companies, including
divisions of larger companies, that have significantly greater financial,
technological and marketing resources than TransDigm. The niche markets within
the aerospace industry served by TransDigm 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, TransDigm knows of no single competitor
that provides the same range of products and services as those provided by
TransDigm. Competitors in TransDigm'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. Some of TransDigm's competitors have
significantly greater financial, technological and marketing resources than
TransDigm. TransDigm 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 TransDigm
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. TransDigm, 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 TransDigm 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
TransDigm.
 
    TransDigm 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 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 TransDigm
currently satisfies or exceeds these maintenance standards in its repair and
overhaul services. Several of TransDigm's operating divisions include
FAA-approved repair stations.
 
    TransDigm'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. TransDigm believes that its
operations are in material compliance with OSHA's health and safety requirement.
 
RAW MATERIALS AND PATENTS
 
    The components that TransDigm 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 represented 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. TransDigm also purchases a variety of
manufactured component parts from various suppliers although TransDigm 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 TransDigm's
ability to obtain necessary raw materials and component parts may affect its
ability to meet customer production needs.
 
                                       60
<PAGE>
    TransDigm has various trade secrets, proprietary information, trademarks,
trade names, patents, copyrights and other intellectual property rights which
TransDigm believes, in the aggregate but not individually, are important to its
business.
 
ENVIRONMENTAL MATTERS
 
    TransDigm'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 TransDigm to obtain
and maintain permits in connection with its operations. The extensive regulatory
framework imposes significant compliance burdens and risks on TransDigm.
Although management believes that TransDigm'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 TransDigm's operations will not require
TransDigm to make significant additional expenditures to ensure compliance in
the future. According to some 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. Those 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
those substances at the disposal or treatment site, regardless of whether the
affected site is owned or operated by that person. Because TransDigm owns and/or
operates a number of facilities, and because TransDigm arranges for the disposal
of hazardous materials at many disposal sites, TransDigm may incur costs for
investigation, removal and remediation, as well as, capital costs associated
with compliance. Although those 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
clean-up costs will not be material. See "Risk Factors--Potential Exposure to
Environmental Liabilities." TransDigm does not currently contemplate material
capital expenditures for environmental compliance remediation for fiscal 1999 or
fiscal 2000.
 
    The soil and groundwater beneath TransDigm'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, TransDigm 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 Texas Natural Resources Conservation Commission will not be
material to the financial condition, results of operations or cash flows of
TransDigm.
 
PROPERTIES AND FACILITIES
 
   
    TransDigm 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 TransDigm's headquarters. In
addition, TransDigm leases and operates a 100,000 square foot facility in
Fullerton, California. TransDigm 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, TransDigm had approximately 540 full-time
employees and 45 temporary employees. Approximately 11% of TransDigm 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 TransDigm and these
labor unions expire on April 2002 and November 2000, respectively. TransDigm
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, TransDigm is from time to time
threatened with, or may become a party to, legal actions and other proceedings.
While TransDigm is currently involved in some legal proceedings, management
believes the results of these proceedings will not have a material effect of the
results of operations of TransDigm, in part due to indemnification arrangements.
TransDigm believes that its potential exposure to those legal actions is
adequately covered by its aviation product and general liability insurance.

MANAGEMENT STOCKHOLDERS AGREEMENT
 
    Together with the consummation of the Recapitalization, Holdings, Odyssey
and the employee stockholders of Holdings, including the Named Executive
Officers (the "Management Stockholders")
 
                                       66
<PAGE>
   
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
and including the Rollover Investment and new options and shares obtained in
connection with the Recapitalization, and shares acquired thereafter, including
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, that Management Stockholder will
have certain put rights and Holdings will have certain call rights regarding any
Common Stock or any options to purchase Common Stock, in each case, owned by him
at that time.
 
    Upon Mr. Peacock's cessation of active service as Chief Executive Officer on
or after the third anniversary of the Recapitalization, if TransDigm 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. See "--Employment Agreements." 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 Holdings. 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 types of transfers of Common Stock by Odyssey the Management
Stockholders may participate in those transfers and/or Odyssey may require the
Management Stockholders to transfer their shares in those transactions, in each
case, on a pro rata basis.
 
   
    Pursuant to the Management Stockholders' Agreement, the 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. Those
participation rights will lapse following a public offering of Common Stock if
the Common Stock so offered is then listed on a national exchange or if the
public offering includes 50% or more of the outstanding Common Stock that will
have been issued following the offering.
    
 
EMPLOYMENT AGREEMENTS
 
   
    In connection with the Recapitalization, Holdings will enter into an
employment agreement with each of Messrs. Peacock and Howley. Pursuant to the
agreement with Mr. Peacock, Mr. Peacock will continue to serve as Chairman of
the Board and Chief Executive Officer for a period of at least five years,
provided that after three years, Mr. Peacock may elect to continue his service
either as Chief Executive Officer or as a non-executive Chairman. It is intended
that Mr. Howley will be Mr. Peacock's successor. Pursuant to the agreement with
Mr. Howley, Mr. Howley will continue to serve as President and Chief Operating
Officer of Holdings for a period of at least five years. Those employment
agreements also will provide specified severance benefits in the event of
termination of employment under certain circumstances.
    
 
    Each of those 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
 
                                       67
<PAGE>
"good reason" (all as defined in those 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 those 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.
    
 
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, TransDigm
and any subsidiary of Holdings or TransDigm (the "Plan Participants"). In
addition, the Option Plan will govern those options retained pursuant to the
Rollover Investment (the "Rollover Options"). A total of 12.5% 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
TransDigm 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 earlier termination of
employment.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
TAX ALLOCATION AGREEMENT
 
    TransDigm and Holdings entered into a Tax Allocation Agreement concurrently
with the consummation of the Recapitalization. Under the terms of the Tax
Allocation Agreement, TransDigm is obligated to make payments to Holdings equal
to the amount of income taxes that TransDigm would have owed in respect of
federal and state income taxes on behalf of TransDigm and its subsidiaries if
TransDigm and its subsidiaries were, for tax purposes, a separate consolidated
group.
 
ONE-TIME MANAGEMENT BONUSES
 
    Following the consummation of the Recapitalization, TransDigm 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
 
    TransDigm 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 TransDigm, 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 Holdings. 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
 
    As part of the Recapitalization, TransDigm 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
TransDigm, are managing members of the General Partner of Odyssey.
 
RECAPITALIZATION
 
    As part of the Recapitalization and under the terms of the Merger Agreement,
Phase II Acquisition Corp., a wholly-owned subsidiary of Odyssey, merged with
and into Holdings.
 
    Also, together with the Recapitalization and as part of the consideration
for the Merger, Holdings (1) issued $20.0 million in Holdings PIK Notes and
common stock of Holdings and (2) 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
 
TRANSDIGM
 
    THE NEW CREDIT FACILITY
 
   
    The New Credit Facility, as amended, consists of (1) 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 (2) a term loan facility in
an aggregate principal amount of $124.0 million, consisting of the $62.0 million
Tranche A Facility maturing six years from the Execution Date and the $62.0
million Tranche B Facility maturing seven and a half years from the Execution
Date.
    
 
   
    The New Credit Facility provides that TransDigm shall repay, to the extent
then outstanding, (1) 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 (2) with respect to the Tranche B Facility, (A) $310,000 each of
the first two quarters beginning on August 15, 1999, (B) $155,000 each of the
remaining quarters during the first six years after the Execution Date and (C)
$9,713,333 each of the following six quarters. In addition, subject to some
exceptions, the New Credit Facility requires mandatory repayment of the
outstanding indebtedness under the New Credit Facility and concurrent reduction
to the commitments under the New Credit Facility with the proceeds from (1)
assets sales, (2) issuance of debt, (3) issuance of equity interests and capital
contributions, (4) insurance and condemnation claims, (5) 50% of annual excess
cash flow (as defined in the New Credit Facility) from operations in excess of a
predetermined amount and (6) 100% of any purchase price adjustment in favor of
TransDigm with respect to the acquisition of ZMP, in each case, by or of
Holdings, TransDigm or their subsidiaries. TransDigm 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
(1) Applicable Margin and (2) at the option of TransDigm 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 year equal to (1) in the case of Tranche A
Facility and Revolving Credit Facility, (A) bearing an interest rate determined
by the Base Rate, 2.50% through February 16, 1999 and 2.25%, 2.00%, 1.75% or
1.50% thereafter depending on Holdings' ability to achieve the respective debt
coverage ratio specified in the New Credit Facility and (B) bearing an interest
rate determined by the Eurodollar Rate, 3.50% through February 16, 1999 and
3.25%, 3.00%, 2.75% or 2.50% thereafter depending on Holdings' ability to
achieve the respective debt coverage ratio specified in the New Credit Facility
and (2) in the case of Tranche B Facility (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%.
    
 
    The New Credit Facility contains various covenants, customary for similar
credit facilities or otherwise appropriate under the circumstances, that (1)
restrict Holdings, TransDigm 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 types of restrictions affecting subsidiaries, voluntary
prepayment of other Indebtedness and amendments or modifications to instruments
governing such other Indebtedness and (2) require TransDigm 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 TransDigm. The
indebtedness under the New Credit Facility are secured by a pledge of the stock
of TransDigm and all
 
                                       72
<PAGE>
of its domestic subsidiaries and a perfected lien and security interest in
assets other than real estate (tangible and intangible) of TransDigm, its direct
and indirect subsidiaries and Holdings.
 
HOLDINGS
 
    HOLDINGS PIK NOTES
 
    Concurrently with the issuance of the Old Notes by TransDigm, 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 as part of 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 in the year 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 of the Holdings PIK Notes for five years after their issuance
and thereafter at the prices set forth in the indenture under the terms of 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 of the
Holdings PIK Notes.
 
    The Holdings PIK Notes contain some 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 some respects.
 
                                       73
<PAGE>
                          DESCRIPTION OF THE NEW NOTES
 
    TransDigm 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 as in effect on the
date of the Indenture. A copy of the Indenture may be obtained from TransDigm.
You can find definitions of certain capitalized terms used in the following
summary under "--Certain Definitions." For purposes of this section, references
to (1) "TransDigm" means TransDigm Inc. and not its Subsidiaries or Holdings and
(2) 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 TransDigm, ranking
subordinate in right of payment to all Senior Debt of the Company.
 
    TransDigm 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. TransDigm may change any
Paying Agent and Registrar without notice to holders of the New Notes (the
"Holders"). TransDigm will pay principal, and premium, if any, on the New Notes
at the Trustee's corporate office in New York, New York. At TransDigm'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 as part of 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. TransDigm 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, TransDigm 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, in each
 
                                       74

case, expressed as percentages of the principal amount of the Notes, 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, TransDigm 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, TransDigm 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 of the Notes, plus accrued and unpaid interest
on the notes, 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) TransDigm makes such redemption not more than 120 days after the
    consummation of such Equity Offering.
 
SELECTION AND NOTICE OF REDEMPTION
 
    In the event that TransDigm 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 TransDigm 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 TransDigm 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 TransDigm:
 
(1) in a liquidation or dissolution of TransDigm;
 
(2) in a bankruptcy, reorganization, insolvency, receivership or similar
    proceeding relating to TransDigm or its property;
 
                                       75
<PAGE>
(3) in an assignment for the benefit of creditors; or
 
(4) in any marshalling of TransDigm's assets and liabilities.
 
    TransDigm 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.
 
    TransDigm 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 TransDigm, Holders of these Notes
may recover less ratably than creditors of TransDigm who are holders of Senior
Debt. See "Risk Factors--Subordination."
 
   
    At January 1, 1999 on a pro forma basis as if the aquisition of ZMP and the
related borrowings under the New Credit Facility had occurred on January 1,
1999, the aggregate principal amount of Senior Debt outstanding of TransDigm and
Holdings would have been $133.0 million and $153.2 million, respectively.
    
 
GUARANTEE
 
    The obligations of the Company under the Notes and the Indenture will be
fully and unconditionally guaranteed (the "Guarantees") on a senior subordinated
basis and on a joint and several basis by Holdings and all of the direct and
indirect Domestic Restricted Subsidiaries of TransDigm. 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 TransDigm. 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 TransDigm 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 of the Notes plus accrued interest to the date
of purchase. Within 30 days following the date upon which the Change of Control
occurred, TransDigm must send, by first class mail, a notice to each Holder,
which notice shall govern the terms
 
                                       76
<PAGE>
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 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, TransDigm 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.
    TransDigm'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.
 
    TransDigm 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
TransDigm 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 TransDigm is required to
purchase outstanding Notes pursuant to a Change of Control Offer, TransDigm
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 TransDigm 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.
 
    TransDigm 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 TransDigm complies with the provisions of any such securities laws or
regulations, TransDigm 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.  TransDigm 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, TransDigm and the Guarantors may incur
Indebtedness, including, without limitation, Acquired Indebtedness, and
Restricted Subsidiaries of TransDigm 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 TransDigm would have been greater than 2.0 to
1.0.
 
                                       77
<PAGE>
    LIMITATION ON RESTRICTED PAYMENTS.  TransDigm will not, and will not cause
or permit any of its Restricted Subsidiaries to, directly or indirectly:
 
(1) declare or pay any dividend or make any distribution (other than dividends
    or distributions payable in Qualified Capital Stock of TransDigm) on or in
    respect of shares of TransDigm's Capital Stock to holders of such Capital
    Stock;
 
(2) purchase, redeem or otherwise acquire or retire for value any Capital Stock
    of TransDigm or any direct or indirect parent of TransDigm or any warrants,
    rights or options to purchase or acquire shares of any class of such Capital
    Stock;
 
(3) make any principal payment on, purchase, defease, redeem, prepay, decrease
    or otherwise acquire or retire for value, prior to any scheduled final
    maturity, scheduled repayment or scheduled sinking fund payment, any
    Indebtedness of TransDigm that is subordinate or junior in right of payment
    to the Notes; or
 
(4) make any Investment, other than Permitted Investments (each of the foregoing
    actions set forth in clauses (1), (2), (3) and (4) being referred to as a
    "Restricted Payment");
 
if at the time of such Restricted Payment or immediately after giving effect
thereto:
 
 (i) a Default or an Event of Default shall have occurred and be continuing; or

      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
       TransDigm 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

       Investment, other than a Permitted Investment, made by TransDigm and its
       Restricted Subsidiaries or (B) dividend from, or the sale of the stock

    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 TransDigm (the "Retired Capital Stock") either (A) solely

    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 TransDigm that is subordinate or junior
    in right of payment to the Notes either (A) solely in exchange for shares of
    Qualified Capital Stock of TransDigm, or (B) through the application of net
    proceeds of a substantially concurrent sale for cash, other than to a
    Subsidiary of TransDigm, of (a) shares of Qualified Capital Stock of

    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

    LIMITATION ON ASSET SALES.  TransDigm will not, and will not permit any of
its Restricted Subsidiaries to, consummate an Asset Sale unless:
 
(1) TransDigm 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 TransDigm's Board of Directors;
 
(2) at least 75% of the consideration received by TransDigm 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 TransDigm's or such Restricted Subsidiary's
       most recent balance sheet, of TransDigm 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 TransDigm or any such
       Restricted Subsidiary from such transferee that are converted by
       TransDigm 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 TransDigm 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, TransDigm 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
 
                                       80
<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, TransDigm 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 TransDigm 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 TransDigm
    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 TransDigm or any
    Restricted Subsidiary of TransDigm, 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 TransDigm and its
    Restricted Subsidiaries aggregates at least $10.0 million, at which time
    TransDigm 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, TransDigm 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 TransDigm 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
 
                                       81
<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, TransDigm 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.
 
    TransDigm 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, TransDigm 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 of its compliance with the
applicable securities laws and regulations.
 
    LIMITATION ON DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING
SUBSIDIARIES.  TransDigm 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 TransDigm 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
    TransDigm or any other Restricted Subsidiary of TransDigm; or
 
(3) transfer any of its property or assets to TransDigm or any other Restricted
    Subsidiary of TransDigm, 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 TransDigm 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
 
                                       82
<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 TransDigm'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.  TransDigm will
not permit any of its Restricted Subsidiaries to issue any Preferred Stock,
other than to TransDigm or to a Restricted Subsidiary of TransDigm, or permit
any Person, other than TransDigm or a Restricted Subsidiary of TransDigm, to own
any Preferred Stock of any Restricted Subsidiary of TransDigm, other than
Permitted Subsidiary Preferred Stock. The provisions of this covenant will not
apply to any of the Guarantors.
 
    LIMITATION ON LIENS.  TransDigm 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 TransDigm 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 TransDigm or a Wholly Owned Restricted Subsidiary of
       TransDigm on assets of any Restricted Subsidiary of TransDigm;
 
           (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 TransDigm or any of its
       Restricted Subsidiaries not securing the Indebtedness so Refinanced; and
 
           (f) Permitted Liens.
 
    PROHIBITION ON INCURRENCE OF SENIOR SUBORDINATED DEBT.  TransDigm 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 TransDigm or such Guarantor, as the case
may be.

    MERGER CONSOLIDATION AND SALE OF ASSETS.  TransDigm will not, in a single
transaction or series of related transactions, consolidate or merge with or into
any Person, or sell, assign, transfer, lease, convey or otherwise dispose of or
cause or permit any Restricted Subsidiary of TransDigm to sell, assign,
transfer, lease, convey or otherwise dispose of, all or substantially all of
TransDigm's assets, in each case, determined on a consolidated basis for
TransDigm and TransDigm's Restricted Subsidiaries, whether as an entirety or
substantially as an entirety to any Person unless:
 
        (1) either:
 
           (a) TransDigm shall be the surviving or continuing corporation; or
 
           (b) the Person, if other than TransDigm, formed by such consolidation
       or into which TransDigm is merged or the Person which acquires by sale,
       assignment, transfer, lease, conveyance or other disposition the
       properties and assets of TransDigm and of TransDigm's Restricted
       Subsidiaries substantially as an entirety (the "Surviving Entity"):
 
               (x) shall be a corporation organized and validly existing under
           the laws of the United States or any State thereof or the District of
           Columbia; and
 
               (y) shall expressly assume, by supplemental indenture in form and
           substance satisfactory to the Trustee, executed and delivered to the
           Trustee, the due and punctual payment of the principal of, and
           premium, if any, and interest on all of the Notes and the performance
           of every covenant of the Notes, the Indenture and the Registration
           Rights Agreement on the part of TransDigm to be performed or
           observed;
 
        (2) except in the case of a merger of TransDigm with or into a Wholly
    Owned Restricted Subsidiary of TransDigm and except in the case of a merger
    entered into solely for the purpose of reincorporating TransDigm in another
    jurisdiction, immediately after giving effect to such transaction and the
    assumption contemplated by clause (1)(b)(y) above (including giving effect
    to any Indebtedness and Acquired Indebtedness incurred in connection with or
    in respect of such transaction), TransDigm or such Surviving Entity, as the
    case may be, shall be able to incur at least $1.00 of additional
    Indebtedness pursuant to the "Limitation on Incurrence of Additional
    Indebtedness" covenant;
 
        (3) except in the case of a merger of TransDigm with or into a Wholly
    Owned Restricted Subsidiary of TransDigm and except in the case of a merger
    entered into solely for the purpose of reincorporating TransDigm in another
    jurisdiction, immediately after giving effect to such transaction and the
    assumption contemplated by clause (1)(b)(y) above, including, without
    limitation, giving effect to any Indebtedness and Acquired Indebtedness
    incurred and any Lien granted in connection with or in respect of the
    transaction, no Default or Event of Default shall have occurred or be
    continuing; and
 
        (4) TransDigm 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 TransDigm the Capital Stock of which constitutes all or
substantially all of the properties and assets of TransDigm, shall be deemed to
be the transfer of all or substantially all of the properties and assets of
TransDigm. However, transfer of assets between or among TransDigm and its
Restricted Subsidiaries will not be subject to the foregoing covenant.
 
                                       84
<PAGE>
    The Indenture provides that upon any consolidation, combination or merger or
any transfer of all or substantially all of the assets of TransDigm in
accordance with the foregoing, in which TransDigm is not the continuing
corporation, the successor Person formed by such consolidation or into which
TransDigm 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,
TransDigm 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.  TransDigm 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 TransDigm; PROVIDED, HOWEVER,
that for a transaction or series of related transactions with an aggregate value
of $2.5 million or more, at TransDigm's option, either:
 
        (1) a majority of the disinterested members of the Board of Directors of
    TransDigm 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 TransDigm or
 
        (2) the Board of Directors of TransDigm 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 TransDigm;
 
and PROVIDED, FURTHER, that for an Affiliate Transaction with an aggregate value
of $10.0 million or more the Board of Directors of TransDigm 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
TransDigm.
 
    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 TransDigm or any
    Restricted Subsidiary of TransDigm as determined in good faith by
    TransDigm's Board of Directors or senior management;
 
        (2) transactions exclusively between or among TransDigm 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;
 
                                       85
<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 TransDigm or such Restricted
    Subsidiary in good faith;
 
        (7) payments or loans to employees or consultants that are approved by
    the Board of Directors of TransDigm in good faith;
 
        (8) sales of Qualified Capital Stock;
 
        (9) the existence of, or the performance by TransDigm 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 TransDigm 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.  TransDigm 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 TransDigm of all of TransDigm'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 TransDigm 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 TransDigm 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, TransDigm 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 TransDigm were required to file those 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 TransDigm 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
 
                                       86
<PAGE>
    TransDigm and its Restricted Subsidiaries separate from the financial
    condition and results of operations of the Unrestricted Subsidiaries of
    TransDigm, and, with respect to the annual information only, a report
    thereon by TransDigm's certified independent accountants and
 
        (2) all current reports that would be required to be filed with the
    Commission on Form 8-K if TransDigm 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 TransDigm 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 TransDigm and its Restricted
    Subsidiaries on a stand-alone basis, on the other hand.
 
    In addition, following the consummation of this exchange offer, whether or
not required by the rules and regulations of the Commission, TransDigm will file
a copy of all those 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, TransDigm has agreed that, for so long as any Old 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 and 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 TransDigm 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, after giving effect to
    any applicable grace periods and any extensions of the grace periods, the
    principal amount of any Indebtedness of TransDigm or any Restricted
    Subsidiary of TransDigm 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;
 
                                       87
<PAGE>
        (5) one or more judgments in an aggregate amount in excess of $5.0
    million shall have been rendered against TransDigm 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 TransDigm 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 TransDigm, 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 TransDigm 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 TransDigm 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 TransDigm
    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 TransDigm 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.
 
                                       88
<PAGE>
    Under the Indenture, TransDigm 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
 
    TransDigm 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 TransDigm 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) TransDigm'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
    TransDigm's obligations in connection therewith; and
 
        (4) the Legal Defeasance provisions of the Indenture.
 
    In addition, TransDigm 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) TransDigm 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, TransDigm shall have delivered to
    the Trustee an opinion of counsel in the United States reasonably acceptable
    to the Trustee confirming that
 
           (a) TransDigm 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, TransDigm shall have delivered
    to the Trustee an opinion of counsel in the United States reasonably
    acceptable to the Trustee confirming that the
 
                                       89
<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 TransDigm
    or any of its Subsidiaries is a party or by which TransDigm or any of its
    Subsidiaries is bound;
 
        (6) TransDigm shall have delivered to the Trustee an officers'
    certificate stating that the deposit was not made by TransDigm with the
    intent of preferring the Holders over any other creditors of TransDigm or
    with the intent of defeating, hindering, delaying or defrauding any other
    creditors of TransDigm or others;
 
        (7) TransDigm 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) TransDigm 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 TransDigm.
 
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 TransDigm and thereafter repaid to
       TransDigm or discharged from such trust, have been delivered to the
       Trustee for cancellation or
 
                                       90
<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 TransDigm 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 TransDigm directing the Trustee to apply
       such funds to the payment thereof at maturity or redemption, as the case
       may be; and
 
        (2) TransDigm has paid all other sums payable under the Indenture by
    TransDigm,
 
    The Trustee will acknowledge the satisfaction and discharge of the Indenture
if TransDigm 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, TransDigm 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 TransDigm
    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.
 
                                       91
<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 TransDigm, 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
such terms, as well as any other terms used herein for which no definition is
provided.
 
    "ACQUIRED INDEBTEDNESS" means Indebtedness of a Person or any of its
Subsidiaries existing at the time such Person becomes a Restricted Subsidiary of
TransDigm or at the time it merges or consolidates with or into TransDigm or any
of its Subsidiaries or that is assumed in connection with the acquisition of
assets from such Person and in each case not incurred by such Person in
connection with, or in anticipation or contemplation of, such Person becoming a
Restricted Subsidiary of TransDigm or such acquisition, merger or consolidation.
 
    "AFFILIATE" means, with respect to any specified Person, any other Person
who directly or indirectly through one or more intermediaries controls, or is
controlled by, or is under common control with, such specified Person. The term
"control" means the possession, directly or indirectly, of the power to direct
or cause the direction of the management and policies of a Person, whether
through the ownership of voting securities, by contract or otherwise; and the
terms "controlling" and "controlled" have meanings correlative of the foregoing.
Notwithstanding the foregoing, no Person, other than TransDigm or any Subsidiary
of TransDigm, in whom a Securitization Entity makes an Investment in connection
with a Qualified Securitization Transaction shall be deemed to be an Affiliate
of TransDigm or any of its Subsidiaries solely by reason of such Investment.
 
    "ASSET ACQUISITION" means (a) an Investment by TransDigm or any Restricted
Subsidiary of TransDigm in any other Person pursuant to which such Person shall
become a Restricted Subsidiary of TransDigm, or shall be merged with or into
TransDigm or any Restricted Subsidiary of TransDigm, or (b) the acquisition by
TransDigm or any Restricted Subsidiary of TransDigm of the assets of any Person,
other than a Restricted Subsidiary of TransDigm, other than in the ordinary
course of business.

    Indebtedness determined on a fluctuating basis, to the extent such interest

           (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.
 
   
    TransDigm, the Initial Guarantors and the initial purchasers entered into
the Registration Rights Agreement on December 3, 1998 (the "Issue Date") under
the terms of which each of TransDigm and the Initial Guarantors agreed that they
will, at their expense, for the benefit of holders of the Old Notes (the
"Holders");
    
 
    - 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; and
 
    - 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, TransDigm
      will offer these New Notes in exchange for surrender of the Old Notes.
      TransDigm will keep the Exchange Offer open for not less than 30 days
      after the date notice of the Exchange Offer is mailed to the Holders. For
      each of the Old Notes surrendered to TransDigm in to the Exchange Offer,
      the Holder who surrendered that Old Note will receive a New Note having a
      principal amount equal to that of the surrendered Old Note. Interest on
      each New Note will accrue (1) from the later of (A) the last interest
      payment date on which interest was paid on the Old Note surrendered in
      exchange for the New Note, or (B) 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 that exchange and
      as to which interest will be paid, the date of that interest payment date
      or (2) if no interest has been paid on that Old Note, from the Issue Date.
 
    If, (1) because of any change in law or in currently prevailing
interpretations of the Staff of the Commission, TransDigm is not permitted to
effect an exchange offer, (2) the Exchange Offer is not consummated by June 6,
1999 or (3) in certain circumstances, certain holders of unregistered Old Notes
so request, or (4) in the case of any Holder that participates in the exchange
offer, that 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, TransDigm will (A)
promptly deliver to the Holders and the Trustee written notice of that event and
(B) 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 its 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 under the
Shelf Registration Statement. TransDigm 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
other actions as are required to permit unrestricted resales of the Old Notes. A
Holder that sells Old Notes relying on 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 some of the civil
liability provisions under the Securities Act in connection with those sales and
will be bound by the provisions of the Registration Rights Agreement that are
applicable to that Holder.
 
    If TransDigm 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,
 
                                      111
<PAGE>
additional interest (the "Additional Interest") shall become payable in respect
of the Old Notes as follows:
 
    - 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 TransDigm has
      consummated or will consummate an exchange offer, TransDigm is required to
      file a Shelf Registration Statement and that 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
      dates, Additional Interest shall accrue on the principal amount of the Old
      Notes at a rate of 0.50% per year for the first 90 days immediately
      following each such filing date, such Additional Interest rate increasing
      by an additional 0.50% per year at the beginning of each subsequent 90-day
      period; or
 
    - 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 that filing in the
      Registration Rights Agreement or (B) notwithstanding that TransDigm has
      consummated or will consummate an exchange offer, TransDigm 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 year for the first 90 days
      immediately following such date, that Additional Interest rate increasing
      by an additional 0.50% per year at the beginning of each subsequent 90-day
      period; or
 
    - if (A) TransDigm 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, unless at that time all Old Notes
      have been disposed of under the Shelf Registration Statement, then
      Additional Interest shall accrue on the principal amount of the Old Notes
      at a rate of 0.50% per year 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 to be effective in the case of
      (B) above, that Additional Interest rate increasing by an additional 0.50%
      per year at the beginning of each subsequent 90-day period;
 
However, the Additional Interest rate on the Old Notes may not accrue under more
than one of the foregoing clauses at any one time and at no time shall the
aggregate amount of Additional Interest accruing exceed in the aggregate 1.0%
per year; and (1) upon the filing of the Exchange Offer Registration Statement
or a Shelf Registration Statement, (2) upon the effectiveness of the Exchange
Offer Registration Statement or a Shelf Registration Statement, or (3) upon the
exchange of New Notes for all Old Notes tendered, or upon the effectiveness of
the Shelf Registration Statement which had ceased to remain effective.
Additional Interest on the Old Notes as a result of that clause, as the case may
be, shall cease to accrue.
 
    Any amounts of Additional Interest 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 DTC and registered in the name of a
nominee of such depositary.
 
THE GLOBAL NOTE
 
    TransDigm expects that according to procedures established by DTC (A) 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 that depositary and (B) ownership of beneficial interests in the
Global Note will be shown on, and the transfer of that ownership will be
effected only through, records maintained by DTC or its nominee and the records
of 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 that 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 of that Global Note. None of TransDigm, 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 those
beneficial ownership interests.
 
    TransDigm 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. TransDigm also expects that payments
by participants to owners of beneficial interests in the Global Note held
through those 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. Those payments
will be the responsibility of those 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, that 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 TransDigm 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 that portion of the aggregate principal amount of New Notes as to which that
participant or those participants has or have given that direction. However, if
there is an Event of
 
                                      113
<PAGE>
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 those procedures and those procedures may be
discontinued at any time. Neither TransDigm 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 TransDigm within 90 days.

            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS
 
    The following general discussion summarizes 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. TransDigm 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 under the terms of the exchange
offer should not constitute a taxable exchange. As a result, a holder (A) should
not recognize taxable gains of loss as a result of exchanging Old Notes for New
Notes under the terms of the exchange offer, (B) the holding period of the New
Notes should include the holding period of the Old Notes exchanged for the New
Notes and (C) the adjusted tax basis of the New Notes should be the same as the
adjusted tax basis, immediately before the exchange of the Old Notes exchange
for the New Notes.
 
                                      115
<PAGE>
                              PLAN OF DISTRIBUTION
 
    Each broker-dealer that receives New Notes for its own account in the
exchange offer must acknowledge that it will deliver a prospectus together with
any resale of those New Notes. This Prospectus, as it may be amended or
supplemented from time to time, may be used by a broker-dealer in the resales of
New Notes received in exchange for Old Notes where those Old Notes were acquired
as a result of market-making activities or other trading activities. TransDigm
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 it in the letter of transmittal for use in any such
resale.
 
    TransDigm 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 those 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.

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, LP (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 as a purchase. Accordingly, the
purchase price has been allocated to the assets acquired and liabilities assumed
based upon their estimated fair value at the date of acquisition, as follows:

</TABLE>
 
    The acquisition was financed with available cash of approximately $10.9
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.

of $135) of $230.
 
    This pro forma information does not purport to be indicative of the results
that actually would have been obtained if the operations had been combined

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. Because TransDigm Holding Company has no operations of its own and,
prior to the Recapitalization, had no assets or liabilities other than its
equity interest in TransDigm, the consolidated financial statements of TransDigm
Holding Company for the three year period ended September 30, 1998 are identical
to the historical consolidated financial statements of TransDigm.
 
    REVENUE RECOGNITION--Revenue is recognized when products are shipped to the
customer. 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.

                 YEARS ENDED SEPTEMBER 30, 1998, 1997 AND 1996
 
3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    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.
 
    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.

</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. The Company is in compliance with all financial covenants of the
credit facility as of September 30, 1998.

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):

    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.

    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's other comprehensive
income consists of the minimum pension liability adjustment. If the Company had
adopted SFAS No. 130, comprehensive income would have been reduced by $252,000,
$122,000, and $177,000 in 1998, 1997, and 1996, respectively. 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)

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):

  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.

                           TRANSDIGM HOLDING COMPANY
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
           THIRTEEN WEEKS ENDED JANUARY 1, 1999 AND DECEMBER 26, 1997
 
1. DESCRIPTION OF THE BUSINESS AND MERGER
 
    TransDigm Holdings Company ("Holdings") 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 bearings and sliding
controls.
 
    On December 3, 1998, Phase II Acquisition Corp. ("Acquiror"), an entity
formed by affiliates of Odyssey Investment Partners, LP ("Odyssey") and Holdings
consummated a definitive agreement and plan of merger (the "Merger Agreement" or
the "Merger"). Pursuant to the terms of the Merger, Acquiror was merged with and
into Holdings, with Holdings being the surviving corporation in the Merger (the
"Surviving Corporation"). In the Merger, owners of Holdings' outstanding common
stock received, in exchange for each outstanding share of common stock (except
for shares held directly or indirectly by Holdings 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, was approximately $299.7
million.
 
    In connection with the Merger, Kelso Investment Associates IV, LP and Kelso
Equity Partners II, LP (collectively "Kelso") retained approximately 15.4% of
the Surviving Corporation's outstanding common stock (the "Rolled Shares"). In
addition, certain members of management of Holdings 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 was treated as a recapitalization (the
"Recapitalization") for financial reporting purposes, which had no impact on the
historical basis of Holdings' consolidated assets and liabilities.
 
    Simultaneously with the Merger, Holdings and TransDigm (collectively with
Marathon, the "Company") refinanced all of its existing debt. The Merger, the
refinancing, and payment of fees and expenses were 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) Holdings PIK Notes of $20 million issued to certain
stockholders. At January 1, 1999, Holdings had $29.0 million available for
working capital, certain permitted acquisitions and general corporate purposes
under the new Senior Credit Facility.
 
    Separate financial statements of TransDigm are not presented since the
Senior Subordinated Notes are guaranteed by Holdings and all direct and indirect
subsidiaries of TransDigm, and since Holdings has no operations or assets
separate from its investment in TransDigm.
 
2. UNAUDITED FINANCIAL INFORMATION
 
    The financial information included herein is unaudited; however, the
information reflects all adjustments (consisting solely of normal recurring
adjustments) that are, in the opinion of management, necessary for a fair
presentation of the Company's financial position and results of operations and
cash flows for the interim periods presented. The results of operations for the
thirteen weeks ended January 1, 1999 are not necessarily indicative of the
results to be expected for the full year.

</TABLE>
 
4. INCOME TAXES
 
    Income tax expense (benefit) as a percentage of income (loss) before income
taxes was (23.3)% for the first quarter of fiscal 1999 compared to 38.6% for the
first quarter of fiscal 1998. The tax benefit recorded for the first quarter of
fiscal 1999 was significantly impacted by the non-deductible expenses incurred
in connection with the Recapitalization.
 
5. REDEEMABLE COMMON STOCK
 
    The redeemable common stock represents the estimated value of common stock
held by management shareholders which have certain put rights.
 
6. CONTINGENCIES
 
    ENVIRONMENTAL--The soil and goundwater 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 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.

           THIRTEEN WEEKS ENDED JANUARY 1, 1999 AND DECEMBER 26, 1997
 
7. NEW ACCOUNTING STANDARD
 
    The Company adopted the provisions of Statement No. 130 of the Financial
Accounting Standards Board "Reporting Comprehensive Income" during the thirteen
weeks ended January 1, 1999. Accordingly, the Company's accumulated other
comprehensive income, consisting solely of its minimum pension liability
adjustment, is reported separately in the accompanying consolidated balance
sheet and statement of changes in stockholders' equity. There were no changes in
accumulated other comprehensive income during the thirteen weeks ended January
1, 1999 and December 26, 1997.
 
   
8. SUBSEQUENT EVENT
    
 
   
    On April 23, 1999, TransDigm acquired ZMP, Inc, including all of its
outstanding common stock, for $41 million. The purchase price is subject to
adjustment for changes in working capital and other matters as defined in the
merger agreement.

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.

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.

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%.

8. SALES TO MAJOR CUSTOMERS
 
    The Company made sales to various U.S. governmental agencies representing
14.0% and 7.0% of net sales in 1996 and 1995, respectively. Sales to two of the
Company's nongovernmental customers represent 25.6% and 22.8%, respectively, of
net sales in 1996 and 31.3% and 29.5% respectively, in 1995. These customers
also represented 20.4% and 34.6%, respectively, of outstanding trade receivables
at December 31, 1996 and 28.0% and 22.6%, respectively, at December 31, 1995. In
the normal course of business, the Company extends credit on open account to its

Company's products. Extensions of credit to all customers are closely monitored
and no significant credit losses have occurred during the years ended December
31, 1996 and 1995.

10. RELATED PARTY TRANSACTIONS
 
    The Company paid management fees of $200,000 and $181,000 during 1996 and
1995, respectively, which are included in general and administrative expenses,
to its principal shareholder under an agreement which calls for quarterly
installments equal to 1.0% of quarterly net sales. Included in accrued
liabilities other (Note 5) are management fees payable of $51,000 and $46,000 as
of December 31, 1996 and 1995, respectively.
 
    Included in treasury stock at December 31, 1996 and 1995 are 75 shares of
the Company's common stock which were repurchased from a former employee during
1995 for approximately $8,000.
 
11. STOCK OPTIONS
 
    The Company established an incentive stock option plan in 1994 under which
options to acquire an aggregate of 3,000 shares of the Company's common stock
may be granted to employees and consultants of the Company. The plan requires
that the exercise price for each stock option be not less than 100% of the fair
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
options are nontransferable and are cancelable if the optionee's employment or
other association with the Company is terminated for any reason. The plan and
all underlying options terminate on January 1, 2005 or earlier. As of December
31, 1996 and 1995, options of 2,681 and 2,531, respectively, had been granted
under the plan.

</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.
 
    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.

ZMP, Inc.
Glendale, California
 
    We have audited the accompanying consolidated balance sheet of ZMP, Inc. and
subsidiary (the "Company") as of June 26, 1998, and the related consolidated
statements of income and retained earnings and of cash flows for the year then
ended. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audit.
 
    We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
consolidated financial statement presentation. We believe that our audit
provides a reasonable basis for our opinion.
 
    In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of the Company as of June 26,
1998, and the results of its operations and its cash flows for the year then
ended in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                        FOR THE YEAR ENDED JUNE 26, 1998
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
   
    ORGANIZATION AND NATURE OF BUSINESS--ZMP, Inc. (the "Company" or "ZMP"),
through its wholly-owned subsidiary, Adams Rite Aerospace (ARA), designs and
manufactures specialized parts and systems for the aerospace industry. The
Company operates only in this industry segment and does not have significant
foreign operations.
    
 
   
    Effective June 29, 1996, the Company adopted a plan to recapitalize the
Company and restructure the senior subordinated notes payable. Under this plan,
the Company exchanged 9,308 shares of common stock for all of the previously
outstanding Series AA, Series A and Series B preferred stock. The Company also
issued 90,692 shares of common stock as payment of $9,766,000 of senior
subordinated notes payable and accrued interest to the majority stockholder.
Additionally, the terms of the remaining senior subordinated notes payable were
amended to accrue interest at 12%, payable semiannually on December 31 and June
30, with the principal due on December 31, 1998. On June 8, 1998, ZMP signed an
agreement to extend the maturity date of the senior subordinated notes payable
to December 31, 1999. The Company accounted for the recapitalization as a
deficit reclassification quasi-reorganization and eliminated the prior
accumulated deficit against additional paid-in capital. The fair value of the
Company's net assets exceeded the book value and, therefore, no adjustment to
carrying values was recorded.
    
 
    On February 23, 1998, the Company relocated its primary operating facility
from Glendale, California to a 100,000-square-foot facility located in
Fullerton, California.
 
    CONSOLIDATION POLICY--The accompanying consolidated financial statements
include the accounts of ZMP and ARA. All significant intercompany accounts and
transactions have been eliminated in consolidation.
 
   
    REPORTING PERIOD--The Company's fiscal year is the 52 or 53 week period
ending on the Friday nearest June 30. Fiscal 1998 contained 52 weeks.
    
 
    REVENUE RECOGNITION, CONCENTRATION OF CREDIT RISK AND EXPORT SALES--The
Company recognizes revenue from product sales upon shipment. Substantially all
of the Company's accounts receivable are due from companies in the aerospace
industry located throughout the United States and internationally. The Company
performs periodic credit evaluations of its customers' financial condition and
generally does not require collateral. Receivables are generally due within 30
days; however, some European customers have payment terms ranging from 60 to 90
days. Export sales to customers, primarily in western Europe, were $6.5 million
for the year ended June 26, 1998.
 
   
    CASH AND CASH EQUIVALENTS--The Company considers all highly liquid financial
instruments with an original maturity of three months or less to be cash
equivalents.

</TABLE>
 
    EQUIPMENT AND IMPROVEMENTS--Equipment and improvements are stated at cost.
Depreciation of equipment is provided for using the straight-line and
accelerated methods over the estimated useful lives of the equipment, which
range from three to ten years. Amortization of leasehold improvements is
provided for using the straight-line method over the shorter of the lease term
or the useful life of the improvement.
 
    IMPAIRMENT--The Company reviews the recoverability of long-term and
intangible assets to determine if there has been any impairment. This assessment
is performed based on the estimated undiscounted future cash flows from
operating activities compared with the carrying value of the related assets. If
the future cash flows (undiscounted and without interest charges) were less than
the carrying value, a writedown would be recorded to reduce the related asset to
its estimated fair value.
 
    MAJOR CUSTOMERS--During fiscal 1998, the Company had sales to one customer
representing 20% of net sales. Accounts receivable from such customer represent
14% of total receivables at June 26, 1998.
 
    INCOME TAXES--Deferred income taxes represent the tax consequences of
differences between the income tax bases of assets and liabilities and their
bases for financial reporting purposes. A valuation allowance is provided when
it is more likely than not that some portion or all of the deferred income tax
assets will not be realized.
 
    USE OF ESTIMATES--The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
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.
 
   
    LITIGATION--The Company does not anticipate that adverse outcomes in
currently pending litigation would have a material adverse effect on its
business, results of operations or financial condition.

discretion of management and may be discontinued at any time. There are no other
postretirement benefits. Included in the consolidated statement of income and
retained earnings are expenses for the retirement plan of $127,000 for the year

    The Company also has a deferred compensation agreement with a key employee
that provides for payment from a trust upon retirement or other termination of
employment. The Company may at any time make additional deposits of cash or
other property in trust to the plan.
 
    As of June 26, 1998, the plan assets are invested primarily in mutual funds
and are subject to reinvestment as determined by the key employee. Based on the
nature of the investments and the ability of the key employee to alter the
investment strategy, such plan assets have been classified as trading securities
as defined in Statement of Financial Accounting Standards No. 115, ACCOUNTING
FOR CERTAIN INVESTMENTS IN DEBT AND EQUITY SECURITIES. Additionally, the plan
assets are classified as noncurrent based on the key employee's intent of
maintaining the assets within the plan for a minimum of one year.

4. STOCK COMPENSATION EXPENSE
 
   
    On August 3, 1998, the Company entered into a series of agreements with its
Chief Executive Officer (the "Executive"). Under the agreements, the Executive
was granted the right to purchase 8,695 shares of common stock at a price of
$39.41 per share. The stock warrants vest over three years, with immediate
vesting of all warrants upon a change of control, such as the merger described
in Note 1. Compensation expense representing the difference between the fair
value of common stock and the warrant price was recognized by the Company as a
result of the warrant agreements and is presented separately on the accompanying
consolidated statement of income for the twenty-six weeks ended December 25,
1998.
    
 
   
    In conjunction with the warrant grant, the Company provided the Executive
with a $288,000 loan evidenced by a demand note, bearing interest at 5.0%, and
collateralized by the Company's common stock held by the Executive, to pay for
the tax consequences, to the Executive, related to the warrant

grant. Additionally, in December 1998, the Company provided the Executive with a
second $214,000 loan evidenced by a demand note, bearing interest at the
Internal Revenue Service's permitted minimum interest rate (4.28% at December
25, 1998), and collateralized by the Company's common stock held by the
Executive. The second loan was intended to provide the Executive with sufficient
funds to retire a commercial loan obtained by the Executive in conjunction with
the exercise of 5,435 warrants that immediately vested upon the warrant grant.
Both loans are included in accounts receivable in the accompanying balance
sheet.
    
 
   
5. LINE OF CREDIT
    
 
   
    In September 1998, ARA renewed a revolving line of credit through July 2000
which provides for maximum borrowings of $2,000,000, limited to 80% of eligible
accounts receivable, as defined, and includes a sub-limit feature for the
issuance of commercial letters of credit in an amount not to exceed $1,000,000.
Borrowings under the revolving credit facility bear interest at the bank's prime
rate plus .25% (7.75% at December 25, 1998). The revolving credit facility was
not utilized by ARA during the two 26 week periods ended December 25, 1998 and
December 26, 1997. The availability of funds under the revolving credit facility
terminates upon a change of control of the Company.

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    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), (iv) the Amended and Restated Articles of
Incorporation (dated April 23, 1999) of ZMP, Inc. (filed herewith as Exhibit
3.10) and (v) the Articles of Incorporation (dated July 30, 1986) and the
amendments thereto (dated September 12, 1986, January 27, 1992, December 31,
1992 and August 11, 1997) of Adams Rite Aerospace, Inc. (filed herewith as
Exhibits 3.12, 3.13, 3.14, 3.15 and 3.16, respectively), provide that subject to
certain exceptions, TransDigm Holding Company, TransDigm Inc., Marathon Power
Technologies Company, ZMP, Inc. and Adams Rite Aerospace, Inc. (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
    
 
                                      II-1
<PAGE>
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 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.
 
                                      II-5

    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 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.

cash flows for each of the three years in the period ended September 30, 1998
and have issued our report thereon dated November 9, 1998 (December 3, 1998 as

be paid in accordance with Section 8.3(f)). The amount of the Purchase Price
remaining after the payments described in clauses (i) through (iv) above is
hereinafter referred to as the "Base Equity Price".

                  (b) The Base Equity Price shall be paid or applied as follows:
(i) Buyer shall cause the Surviving Corporation to retain (for ultimate payment
to the holders of Dissenting Shares if and to the extent required to be so paid)
an amount equal to the Base Equity Price multiplied by a fraction, the numerator
of which is the number of Dissenting Shares, and the denominator of which is the
number of ZMP Shares plus the number of Dissenting Shares (the "Dissenting
Shares Amount"); (ii) Buyer shall deliver to the Escrow Agent (I) an amount
equal to the sum of (x) $3,000,000 and (y) if, and only if, there are any
Dissenting Shares, an additional $200,000 for deposit in one escrow account (the
"Escrow Account") and (II) an amount equal to the sum of $750,000 for deposit in
a separate escrow account (the "Glendale Escrow Account"); and (iii) Buyer shall
cause the Surviving Corporation to pay to each holder of ZMP Shares or options
or warrants to acquire ZMP Shares an amount equal to such holder's Applicable
Percentage of the Base Equity Price remaining after the retention and payment
described in clauses (i) and (ii) above. There shall be deducted from any
payment due to a holder under clause (iii) above (x) any exercise price payable
by such holder under such option or warrant to acquire ZMP Shares and (y) any
amount owed by such holder to ZMP or ARA, including, in the case of Collins, the
Collins Note Amount. As used herein, "Merger Consideration" means the aggregate
amount per ZMP Share payable in the Merger, including any amounts payable to the
holders of ZMP Shares pursuant to this Section 2.8 and Sections 2.10, 2.11, 2.12
and 8.3 hereof.

                  Notwithstanding anything to the contrary set forth herein, the
amount of Merger Consideration to be received by the holders of ZMP Shares upon
surrender of their share certificates, letter of transmittal and other required
documentation shall be reduced by the amount, if any, the Company is required to
deduct and withhold with respect to the making of such payment under the Code,
or any provision of state, local or foreign tax law; provided that if any
amounts are so deducted and withheld as Taxes, such amounts shall be treated as
having been paid to the holder of such ZMP Shares.

                  Section 2.9 PERFORMANCE AT THE CLOSING.

                  (a) DELIVERIES BY ACQUISITION. At the Closing, and subject to
Section 2.9(b) below, Buyer, Acquisition and the Surviving Corporation will make
the payments contemplated by Section 2.8.



                                       11

                  (b) SURRENDER OF CERTIFICATES REQUIRED FOR PAYMENT. Any
payment described herein to any Selling Shareholder is conditional upon the
surrender to Buyer by such Selling Shareholder of its stock certificates and any
documentation evidencing any option to acquire ZMP Shares and a letter of
transmittal substantially in the form attached hereto as Exhibit E. Buyer agrees
to make payment immediately upon such surrender (i) by check delivered to each
Selling Shareholder to its most recent registered address on the Company's stock
records, or, if a Selling Shareholder provides Buyer with an alternate address
to which payment should be delivered, to such alternate address or (ii) if a
Selling Shareholder provides Buyer with wire instructions for delivery of such
payment, in immediately available funds to the bank and account therein
identified.

                  No interest shall be paid or accrued on any amount payable
upon the surrender of ZMP Shares. If payment is to be made to a Person other
than the Person in whose name a share certificate surrendered is registered, it
shall be a condition of payment that the share certificate so surrendered shall
be properly endorsed (signature guaranteed) or otherwise in proper form for
transfer and that the Person requesting such payment shall pay all transfer and
other taxes required by reason of the payment to a Person other than the
registered holder of the share certificate, or establish to the satisfaction of
Buyer that such tax has been paid or is not applicable, or provide assurance
reasonably satisfactory to Buyer that any such tax will be paid by such Person.

                  (c) DELIVERIES BY SHAREHOLDERS' REPRESENTATIVE. Shareholders'
Representative shall, to the extent it has access thereto and to the information
required thereunder, provide any forms or certificates required by any state or
local taxing authorities to relieve Buyer of any obligation to withhold any
portion of the Merger Consideration.

                  Section 2.10 POST-CLOSING PURCHASE PRICE ADJUSTMENT.

                  Following the Closing, the Merger Consideration shall be
adjusted as provided herein to reflect changes in Net Working Capital as
determined based on the Closing Date Statement of Net Working Capital compared
to the Target Net Working Capital.

                  (a) Within 60 days following Closing, Buyer and the Surviving
Corporation shall cause to be prepared and delivered to the Shareholders'
Representative a statement of the current assets (the "Current Assets") and the
current liabilities (the "Current Liabilities") of the Company and ARA as of the
close of business on the Friday immediately preceding the Closing (the "Closing
Date Statement of Net Working Capital") along with supporting materials and
calculations and a calculation of the amount, if any, due to the Selling
Shareholders or Buyer as a result of the adjustments set forth in this Section
2.10. The Current Assets and Current Liabilities set forth on the Closing Date
Statement of Net Working Capital shall be determined in accordance with GAAP
applied in the manner, and according to the principles, applied in the
preparation of the Audited Financial Statements as of and for the period ended
June 26, 1998; provided, however, that in determining Current Assets and Current
Liabilities, the exclusions and adjustments described on Schedule 2.10 shall be
given effect. Upon the request of Shareholders' Representative, Buyer and the
Company shall take such steps as may be reasonably necessary to permit a
representative of the Shareholders' Representative to observe all procedures
undertaken in the preparation of the Closing Date Statement of Net Working
Capital and to provide the 



                                       12
<PAGE>

Shareholders' Representative access at all reasonable times to the personnel,
properties, books and records of the Company and ARA for the purpose of
reviewing and ascertaining the accuracy of the Closing Date Statement of Net
Working Capital.

                  (b) Within 30 days after receipt of the Closing Date Statement
of Net Working Capital, the Shareholders' Representative shall, in a written
notice to Buyer, either accept the Closing Date Statement of Net Working Capital
or describe in reasonable detail, in writing, any proposed adjustments and the
reasons therefor. No such written notice shall be delivered to Buyer if the net
proposed adjustments in the aggregate amount to an increase in Net Working
Capital of less than $25,000. If the Buyer has not received such notice of
proposed adjustments within such 30 day period, the Shareholders' Representative
will be deemed irrevocably to have accepted the Closing Date Statement of Net
Working Capital. In the event that Shareholders' Representative and Buyer are
not able to agree on the Net Working Capital within 30 days from and after the
receipt by Buyer of any adjustments proposed by the Shareholders'
Representative, such dispute shall be submitted to Arthur Andersen LLP for
computation or verification in accordance with the provisions of this Agreement.
Such firm shall determine as promptly as practicable, but in any event within 30
days of the date on which such dispute is referred to such firm, whether the
Closing Date Statement of Net Working Capital was prepared in accordance with
the standards set forth in this Agreement on the basis solely of the written
submissions of the parties, and whether and to what extent (if any) Net Working
Capital as shown thereon requires adjustment. The results of such accounting
firm's report shall be binding, conclusive and non-appealable upon Shareholders'
Representative, the Selling Shareholders and Buyer, and such accounting firm's
fees and expenses shall be borne equally by Buyer, on one hand, and the Selling
Shareholders (through a reduction in any amount owed to them under this Section
2.10 or, if no such amount is owed to them, through a payment out of the Escrow
Account) on the other. Buyer and the Shareholders' Representative will jointly
instruct the Escrow Agent, in writing, to make any such payment.

                  (c) Upon acceptance of the Closing Date Statement of Net
Working Capital by Buyer or the resolution of any disputes, (i) if Net Working
Capital on the Closing Date as so determined is greater than the Target Net
Working Capital by more than $25,000, the Merger Consideration shall be
increased by such amount and Buyer shall promptly, but no later than 5 days
after final determination, pay or cause the Surviving Corporation to pay to each
Selling Shareholder such Selling Shareholder's Applicable Percentage of the
amount of such excess, together with interest thereon from the Closing Date to
the date of payment thereof as determined below, and (ii) if Net Working Capital
on the Closing Date as so determined is less than the Target Net Working Capital
by more than $25,000, the Shareholders' Representative and the Buyer shall
promptly, but no later than 5 days after such final determination, instruct the
Escrow Agent in writing to pay to Buyer from the Escrow Account the amount of
such difference, together with interest thereon from the Closing Date to the
date of payment thereof as determined below.

                  (d) For the purposes of this Section 2.10, interest will be
payable at the applicable federal rate (as defined in Section 1274 of the Code),
or, if that rate is no longer established or published, a comparable interest
rate. For purposes of this Section 2.10, interest shall be calculated based on a
365 day year and the actual number of days elapsed.

                  Section 2.11 DISSENTING SHARES. Notwithstanding anything in
this Agreement to the contrary, shares of ZMP Common Stock that are issued and
outstanding immediately prior to the Effective Time and that are held by a
stockholder who has the right (to the extent such right is available by law) to
demand and receive payment of the fair value of such holder's stock pursuant to
California law shall not be converted into the right to receive the Merger
Consideration (unless and until such holder shall have failed to perfect or
shall have effectively withdrawn or lost such right under California law, as the
case may be) (such shares, the "Dissenting Shares"), but the holder thereof
shall only be entitled to such rights as are granted by California law. If such
holder shall have so failed to perfect or shall have effectively withdrawn or
lost such right, such holder's shares of ZMP Common Stock shall thereupon no
longer be Dissenting Shares, but shall be deemed to have been converted at the
Effective Time into the right to receive the Merger Consideration (without any
interest thereon), and the Merger Consideration payable in respect thereof and
in respect of all other ZMP Shares shall be adjusted to yield the results that
would have obtained if such shares had been treated as ZMP Shares rather than
Dissenting Shares at the Closing. If the holder of any shares of ZMP Common
Stock shall become entitled to receive payment for such shares pursuant to
Section 1300 of the California Corporations Code ("Section 1300 Payment") then
such payment shall be made by the Surviving Corporation with no cost or other
liability to any of the Selling Shareholders or the Shareholders'
Representative, except as provided or referred to in the next sentence. Pursuant
to Section 7.1(4), the Buyer Indemnitees shall be indemnified against all Losses
incurred by them (including Section 1300 Payments and payments required
hereunder out of the Dissenting Share Amount) in connection with or as a result
of the existence of Dissenting Shares at the Closing if and to the extent that
such Losses or payments exceeds the Dissenting Share Amount.

                  Section 2.12 SPECIAL PURCHASE PRICE ADJUSTMENT

Following the Closing, the Merger Consideration shall be adjusted as follows:

                  (a)(i) If a Boeing Contract is executed and delivered by
Boeing and ARA on or prior to the Boeing Determination Date, within 10 business
days of such execution and delivery Buyer shall cause to be prepared and
delivered to the Shareholders' Representative (x) a statement, along with a copy
of a Boeing Contract, and if requested by Shareholders' Representative, and
calculations, setting forth the amount due to the Buyer, if any, as a result of
the calculations set forth in Section 2.12(a)(iii) or (y) a statement that no
amount is due to Buyer as a result of the calculations set forth in Section
2.12(a)(iii).

                  (ii) Within 10 business days after receipt of a statement
delivered pursuant to Section 2.12(a)(i)(x), the Shareholders' Representative
shall, in a written notice to the Buyer, either accept such statement or
describe in reasonable detail any proposed adjustments and the reasons therefor.
If Buyer has not received such notice of proposed adjustments within such 10
business day period, the Shareholders' Representative will be deemed to
irrevocably to have accepted such statement. In the event that the Shareholders'
Representative and the Buyer are not able to agree on such statement within 10
business days of receipt by Buyer of any adjustments proposed by Shareholders'
Representative, such dispute shall be submitted to Arthur Andersen LLP for
computation or verification in accordance with this Agreement.



                                       14
<PAGE>

                  (iii) Upon acceptance by the Shareholders' Representative of
the statement delivered pursuant to Section 2.12(a)(i)(x) or the resolution of
any disputes, if the Proposed Boeing Revenue is less than the Boeing Target
Amount, the Merger Consideration will be decreased by an amount equal to the
product of (x) the Boeing Target Amount minus the Proposed Boeing Revenue and
(y) the Fixed Multiplier. If the Merger Consideration is so decreased, the
Shareholders' Representative and the Buyer shall promptly, but in no event later
than five days after such final determination, instruct the Escrow Agent in
writing to pay Buyer from the Escrow Account the amount of such decrease.

                  (b) If no Boeing Contract has been executed and delivered by
Boeing and ARA on or prior to the Boeing Determination Date, the Buyer shall
cause to be prepared and delivered to Shareholders' Representative a statement
pursuant to Section 2.12(a)(i)(x) setting forth the amount due to the Buyer as a
result of the calculations set forth in Section 2.12(a)(iii) assuming for
purposes of such calculation that Proposed Boeing Revenue equals zero.

                 (c) Notwithstanding anything to the contrary herein, the
parties hereto agree that any amounts payable to the Buyer under or pursuant to
this Section 2.12 will be paid solely out of the Escrow Account, in accordance
with this Agreement, and none of the Selling Shareholders will have any
obligation to make (or otherwise with respect to) any such payments other than
from the Escrow Account. Buyer acknowledges that the payments contemplated
hereunder may exceed the amount on deposit in the Escrow Account and that such
payments may exhaust the Escrow Account and that Buyer shall not be entitled to
payment from any other source, including the Glendale Escrow Account.

                 (d) Notwithstanding anything to the contrary herein, if a part
or parts set forth on Schedule A is not set forth in the Boeing Contract as
executed and delivered by the parties and, in the Shareholders' Representative's
reasonable and good faith judgement, such part or parts may be contained in a
subsequent Boeing Contract to be executed and delivered prior to the Boeing
Determination Date the Boeing Target Amount shall be recomputed for purposes of
the calculation set forth in Section 2.12(iii) to exclude such part or parts. If
a subsequent Boeing Contract containing the part or parts so excluded is
executed and delivered prior to the Boeing Determination Date, a separate
calculation shall be made pursuant to Section 2.12(iii) with respect to such
part or parts, utilizing a target amount based solely on such part or parts. If
such subsequent Boeing Contract containing the part or parts so excluded is not
executed and delivered prior to the Boeing Determination Date, a separate
calculation shall be made pursuant to Section 2.12(b) with respect to such part
or parts, utilizing a target amount based solely on such part or parts.

                 (e) Buyer, the Company and ARA agree to use their commercially
reasonable efforts to execute and deliver the Boeing Contract and to negotiate
its terms and conditions in good faith. Notwithstanding the foregoing sentence
or anything to the contrary herein, Buyer, the Company and ARA shall be under no
obligation to execute or deliver a Boeing Contract or any other contract with
Boeing that is not on substantially the terms and conditions set forth in the
Boeing Proposal.

                         REPRESENTATIONS AND WARRANTIES

                  Section 3.1 REPRESENTATIONS AND WARRANTIES BY BUYER AND
ACQUISITION. As of the date hereof and as of the Closing Date (except to the
extent any of the following speaks as of a specific date, such as the date
hereof), Buyer and Acquisition each represents and warrants to, and agrees with,
the Company for the benefit of the Selling Shareholders as follows:

                  (a) ORGANIZATION AND RELATED MATTERS. Each of Buyer and
Acquisition (i) is a corporation duly organized, validly existing and in good
standing under the respective Laws of the jurisdiction of its incorporation or
organization and (ii) has all necessary corporate power and authority to own its
properties and assets and to carry on its businesses as now conducted except
where the failure to be so organized or validly existing, to be in good
standing, or to have such power and authority does not constitute a material
adverse effect on the ability of either Buyer or Acquisition to consummate the
transactions contemplated by this Agreement.

                  (b) CAPITAL STOCK. All of the outstanding shares of capital
stock of each of Buyer and Acquisition will, at the Closing Date, be duly
authorized, validly issued, fully paid and non-assessable, and owned free and
clear of any Encumbrances, other than Permitted Encumbrances.

                  (c) AUTHORIZATION. Each of Buyer and Acquisition has the
necessary corporate power and authority to execute, deliver and perform this
Agreement and the other Transaction Documents and to consummate the transactions
contemplated by this Agreement and the other Transaction Documents. The
execution, delivery and performance of this Agreement and the other Transaction
Documents by each of Buyer and Acquisition has been duly and validly authorized
by the respective Boards of Directors of Buyer and of Acquisition and by all
other necessary corporate action on the part of Buyer and Acquisition. Each of
the Agreement and the Voting Agreement constitutes (and the Escrow Agreement
will, at Closing, constitute) the legally valid and binding obligation of each
of Buyer and Acquisition, enforceable against each of Buyer and Acquisition in
accordance with its terms except as such enforceability may be limited by
bankruptcy, insolvency, reorganization, moratorium and other similar Laws and
equitable principles relating to or limiting creditors' rights generally.

                  (d) NO CONFLICTS. Except as set forth on Section 3.1D of the
Disclosure Schedule, the execution, delivery and performance by each of Buyer
and Acquisition of this Agreement and the other Transaction Documents and the
transactions contemplated thereby will not (i) violate or conflict with the
provisions of, or constitute a breach or default whether upon lapse of time
and/or the occurrence of any act or event or otherwise under (A) the charter
documents or bylaws of either Buyer or Acquisition, (B) any Law to which either
Buyer or Acquisition is subject, or (C) any Contract to which either Buyer or
Acquisition is a party or (ii) require any consent, waiver, authorization or
approval of, or the making of any filing with or giving of notice to, any Person
or Governmental Entity (other than as required under the Hart-Scott-Rodino Act).

                  (e) LEGAL PROCEEDINGS. There is no Action pending,
contemplated or threatened against either Buyer or Acquisition or any of their
respective properties or assets (real, personal or mixed, tangible or
intangible) which individually, or when aggregated with one or more other
Actions, has or might reasonably be expected to have a material adverse effect
on the ability of either Buyer or Acquisition to perform this Agreement or any
other aspect of the transactions contemplated by this Agreement.

                  (f) INVESTMENT REPRESENTATION. Each of Buyer and Acquisition
is aware that the shares of ZMP Common Stock are not registered under the
Securities Act. Each of Buyer and Acquisition possesses such knowledge and
experience in financial and business matters that each is capable of evaluating
the merits and risks of its investments hereunder. Buyer is acquiring the shares
of ZMP Common Stock for its own account, for investment purposes only and not
with a view to the distribution thereof. Buyer agrees that the ZMP Common Stock
will not be sold, transferred, offered for sale, pledged, hypothecated or
otherwise disposed of without registration under the Securities Act, except

is an "accredited investor" as defined in Regulation D promulgated under the
Securities Act.

                  (g) INVESTIGATION. Each of Buyer and Acquisition has conducted
its own independent review and analysis of the business, operations, assets,
liabilities, results of operations, financial condition, software, technology
and prospects of the Company and ARA and each of Buyer and Acquisition
acknowledges that it has been provided access to the personnel, properties,
premises and records of the Company and ARA for such purpose.

                  (h) NO BROKERS OR FINDERS. No agent, broker, finder, or
investment or commercial banker, or other Person or firm engaged by or acting on
behalf of Buyer in connection with the negotiation, execution or performance of
this Agreement or the transactions contemplated by this Agreement, is or will be
entitled to any broker's or finder's or similar fee or other commission as a
result of this Agreement or such transactions.

                  Section 3.2 REPRESENTATIONS AND WARRANTIES BY THE COMPANY. As
of the date hereof and as of the Closing Date (except to the extent any of the
following speaks as of a specific date, such as the date hereof), the Company
represents and warrants to, and agrees with, Buyer and Acquisition as follows:

                  (a) ORGANIZATION AND RELATED MATTERS. Each of the Company and
ARA (i) is a corporation duly organized, validly existing and in good standing
under the respective Laws of the jurisdiction of its incorporation or
organization, (ii) has all necessary corporate power and authority to own,
operate or lease the properties and assets now owned, operated or leased by it
and to carry on its respective business as now conducted and (iii) is duly
qualified or licensed to do business as a foreign corporation in good standing
in all jurisdictions in which the character or the location of the assets owned,
operated or leased by any of them or the nature of the business conducted by any
of them requires licensing or qualification, except in the cases of clauses (ii)
and (iii) where the failure to have such power and authority or to be so
qualified or licensed does not constitute a Material Adverse Effect. All
jurisdictions referred to in clause (iii) above are set forth in Section 3.2A of
the Disclosure Schedule. All corporate actions taken by the Company and ARA have
been duly authorized, and the Company and ARA have not taken any action that 



                                       17
<PAGE>

in any respect conflicts with, constitutes a default under or results in a
violation of any provision of its Certificate of Incorporation or By-Laws. The
Board of Directors of the Company, at a meeting duly called and held, has (i)
determined that this Agreement and the transactions contemplated hereby,
including the Merger, taken together are fair to and in the best interest of the
holders of ZMP Common Stock and (ii) resolved to recommend that the holders of
ZMP Common Stock approve this Agreement and the transactions contemplated
herein, including the Merger.

                  (b) STOCK. The Company owns, directly or indirectly, all of
the outstanding capital stock of ARA free and clear of all Encumbrances. The
authorized capital stock of the Company consists of 108,695 shares of common
stock, $.001 par value, of which 105,435 shares are issued and outstanding and
3,260 shares are reserved for issuance upon exercise of a warrant, as set forth
in Section 3.2B of the Disclosure Schedule. Except as set forth on Section 3.2B
of the Disclosure Schedule, there are no outstanding contracts, options,
warrants, convertible securities or other rights to subscribe for or purchase,
or Contracts or other obligations to issue or grant any rights to acquire, any
Equity Securities or Equity Equivalents of the Company or ARA, or to restructure
or recapitalize the Company or ARA. There are no outstanding Contracts of the
Company or ARA to repurchase, redeem or otherwise acquire any Equity Securities
of any of such Persons or to provide funds to, or make any investment (in the
form of a loan, capital contribution or otherwise) in, any other Person. All
Equity Securities of the Company and ARA are duly authorized, validly issued and
outstanding and are fully paid and nonassessable. There are no preemptive rights
in respect of any Equity Securities of the Company or ARA. Any Equity Securities
of the Company and ARA which were issued and reacquired by any of such Persons
were so reacquired (and, if reissued, so reissued) in compliance with all
applicable Laws, and the Company and ARA have no outstanding obligation or
liability with respect thereto. Other than the Company's ownership of ARA and as
set forth on Section 3.2B of the Disclosure Statement, there are no other
corporations, partnerships, joint ventures, associations or other entities in
which the Company or ARA owns, of record or beneficially, any Equity Securities
or other interest or any right (contingent or otherwise) to acquire the same.
Neither the Company nor ARA is a member of (nor is any part of the business
conducted through) any partnership, nor is the Company or ARA a participant in
any joint venture or similar arrangement. The minute books of the Company and
ARA contain accurate records of all meetings and accurately reflect all other
actions taken by the stockholders and Boards of Directors of the Company and
ARA. Complete and accurate copies of all such minute books and of the stock
register of the Company and ARA have been provided by the Company to the Buyer.
Section 3.2B of the Disclosure Schedule sets forth the total amount of
Indebtedness and the total amount of cash on hand of the Company and ARA on a
consolidated basis, in each case as of the date hereof. Section 3.2B of the
Disclosure Schedule also sets forth all of the stockholders of the Company, the
number of shares of ZMP Common Stock owned by each, and all amounts owed to the
Company or ARA by any holders of ZMP Common Stock.

                  (c) FINANCIAL STATEMENTS; CHANGES; CONTINGENCIES.

                      (i) The Company has delivered to Buyer (i) audited
consolidated balance sheets for the Company and ARA at the end of each fiscal
year ending in June 1996, 1997 and 1998 and the related statements of
operations, cash flow and changes in stockholders' equity for the periods then
ended (collectively, the "Audited Financial Statements") and (ii) 



                                       18
<PAGE>

copies of the unaudited consolidated balance sheet (the "Interim Balance Sheet")
for the Company and ARA at February 20, 1999 and the related statement of
operations, cash flow and changes in stockholders' equity for the period then
ended (collectively with the Interim Balance Sheet, the "Unaudited Financial
Statement" and, together with the Audited Financial Statements, the "Financial
Statements"). The Audited Financial Statements have been examined by the
Company's Auditors, whose reports thereon are included with such financial
statements. The Audited Financial Statements have been prepared in conformity
with GAAP, except for changes, if any, required by GAAP and disclosed therein,
consistently applied throughout the periods covered thereby. Each statement of
operations, cash flow and changes in stockholders' equity in the Audited
Financial Statements (i) was prepared in accordance with the books of account
and other financial records of the Company and ARA and (ii) presents fairly the
results of operations, cash flow and changes in stockholders' equity of the
Company and ARA for the periods covered, and each balance sheet (i) was prepared
in accordance with the books of account and other financial records of the
Company and ARA and (ii) presents fairly the financial condition of the Company
and ARA as of its respective date. Such Audited Financial Statements reflect all
adjustments necessary for a fair presentation. At the date of the most recent
such balance sheet, neither the Company nor ARA had any Liabilities (actual,
contingent or accrued) that, in accordance with GAAP, should have been shown or
reflected therein but were not.

                      (ii) The Unaudited Financial Statements have been prepared
in conformity with GAAP as used in preparing the Audited Financial Statements,
provided that such Unaudited Financial Statements do not include footnotes, and
(i) were prepared in accordance with the books of account and other financial
records of the Company and ARA and (ii) present fairly the consolidated
financial position of the Company and ARA as of such date and the consolidated
results of operations, cash flow and changes in stockholders' equity of the
Company and ARA for such period. At February 20, 1999, neither the Company nor
ARA had any Liabilities (actual, contingent or accrued) that, in accordance with
GAAP as used in preparing the Audited Financial Statements, should have been
shown or reflected in such Unaudited Financial Statements but were not except as
otherwise described in Section 2.8(a)(iii). Accruals for expenses relating to
the transactions contemplated by this Agreement and the other Transaction
Documents and for the Success Bonuses reflected on the Interim Balance sheet
were $194,000 and $380,000, respectively.

                      (iii) Since June 26, 1998 neither the Company nor ARA has
incurred any Liabilities (whether accrued, absolute, contingent or otherwise)
that would be required to be reflected or reserved against in a balance sheet of
the Company and ARA prepared in accordance with GAAP as used in preparing the
Audited Financial Statements, except Liabilities that are reflected or disclosed
in the financial statements referred to in this Section 3.2(c) or were incurred
after February 20, 1999 in the ordinary course of business, consistent with past
practice. Neither the Company nor ARA has any Liabilities (whether accrued,
absolute, contingent or otherwise) that do not relate primarily to the ownership
of its assets, the conduct of its Business or its existence as a corporation.
Other than the TCW Notes or as set forth on Section 3.2B of the Disclosure
Schedule, neither the Company nor ARA has any Liability to any Shareholder of
the Company.

                  The books of account and other financial records of the
Company and ARA: (i) reflect all items of income and expense and all assets and
Liabilities required to be reflected 



                                       19
<PAGE>

therein in accordance with GAAP and (ii) are in all material respects complete
and correct, and do not contain or reflect any material inaccuracies or
discrepancies. Since June 26, 1998, the Company and ARA have maintained systems
of internal accounting controls sufficient to provide reasonable assurance that
material transactions are recorded as necessary to permit preparation of
financial statements in conformity with GAAP and to maintain asset
accountability.

                  Except to the extent, if any, reserved for on the Unaudited
Financial Statements, all Receivables reflected therein arose from the sale of
Inventory or services to Persons not affiliated with ARA or the Company and in
the ordinary course of the Business consistent with past practice other than (i)
notes payable from Collins in the aggregate amount of approximately $512,000 and
(ii) a note payable from a former employee in the approximate amount of $16,000
and except as reserved against on the Unaudited Financial Statements, constitute
or will constitute, as the case may be, only valid and, to the best knowledge of
the Company and ARA, undisputed claims of the Company or ARA and, to the best
knowledge of the Company and ARA, are not subject to valid claims of set off or
other defenses or counterclaims other than normal cash discounts accrued in the
ordinary course of the Business consistent with past practice.

                  Subject to amounts reserved therefor on the Unaudited
Financial Statements, the values at which all Inventories are carried therein
reflect the historical inventory valuation policy of the Company and ARA of
stating such Inventories at the lower of cost (determined on the first in, first
out method) or market value. Except as set forth in Section 3.2C of the
Disclosure Schedule, the Company or ARA, as the case may be, has good and
marketable title to the Inventories free and clear of all Encumbrances other
than Permitted Encumbrances. The Inventories do not consist of any items held on
consignment. Except as set forth on Section 3.2C of the Disclosure Schedule,
neither the Company nor ARA is under any obligation or liability with respect to
accepting returns of items of Inventory or merchandise in the possession of
their customers.

                  Except as reserved against on the Unaudited Financial
Statements, the Inventories do not consist of, in any material amount, items
that are obsolete, damaged or slowmoving. The Inventories are in good and
merchantable condition, are suitable and usable for the purposes for which they
are intended and are in a condition such that they can be sold in the ordinary
course of the Business consistent with past practice.

                  (d) CONDUCT IN THE ORDINARY COURSE; ABSENCE OF CERTAIN
CHANGES, EVENTS AND CONDITIONS. Since June 26, 1998, except as disclosed in
Section 3.2D of the Disclosure Schedule, (i) the Business of the Company and ARA
has been conducted only in the ordinary course and consistent with past practice
and (ii) there has not been, occurred or arisen (and, to the Company's
knowledge, there is no threatened change in or event affecting the Company or
ARA that, taking into account the likelihood of its occurring, would reasonably
be characterized as) any change in or event affecting the Company or ARA that
has had or would reasonably be expected to have had a Material Adverse Effect.
As amplification and not limitation of the foregoing, except as disclosed in
Section 3.2D of the Disclosure Schedule, since June 26, 1998 neither the Company
nor ARA has:

The sole and exclusive business activity in which the Company is engaged is the
ownership, directly or indirectly, of all of the outstanding capital stock
issued by ARA. Additionally, except as set forth on Section 3.2E of the
Disclosure Schedule, the only property, assets and rights (whether tangible or
intangible) owned by the Company is all of the outstanding capital stock issued
by ARA.

                  (f) MATERIAL CONTRACTS. Section 3.2F of the Disclosure
Schedule lists each contract to which the Company or ARA is a party or to which
the Company, ARA or any of their respective properties is subject or by which

Contracts with independent or consultants (or similar arrangements) to which the
Company or ARA is a party and which are not cancelable without penalty or

required to be and are not so reflected on the Unaudited Financial Statements.
True copies of the agreements appearing in Section 3.2F of the Disclosure

Buyer. (1) Each Material Contract is valid and subsisting and binding and
enforceable on the Company or ARA, and to the knowledge of the Company, the
other parties thereto; (2) the Company or ARA has materially performed all its
obligations thereunder to the extent that such obligations to perform have
accrued; and (3) no material breach or default, alleged material breach or

thereto, has occurred. Consummation of the transactions contemplated by this
Agreement and the Escrow Agreement will not (and will not give any Person a
right to) terminate or modify any rights of, or accelerate or augment any
obligation of the Company or ARA under any Material Contract. With respect to
all Contracts (including, without limitation, a subcontract) with the United
States, state or local government or any agency or department thereof

adjustments by the Company or ARA against the government or any third party in

Section 3.2F of the Disclosure Schedule hereof, to the knowledge of the Company
or ARA, there are no requests by the U.S. Government for a contract price
adjustment based upon a claim of defective pricing in excess of $50,000.

                  (g) AUTHORIZATION; NO CONFLICTS. The execution, delivery and

part of the Company. This Agreement has been duly executed 



                                       23

and delivered by the Company and constitutes the legally valid and binding
obligation of the Company, enforceable against the Company in accordance with
their terms except as such enforceability may be limited by bankruptcy,
insolvency, reorganization, moratorium and other similar Laws and equitable
principles relating to or limiting creditors rights generally. The execution,
delivery and performance of this Agreement and the Escrow Agreement by the
Company and the execution, delivery and performance of any related agreements or
contemplated transactions by the Company will not (i) violate, or constitute a
breach or default (whether upon lapse of time, giving of notice or both) under,
the charter documents or by-laws of any of such entities, (ii) violate, or
constitute a breach or default (whether upon lapse of time, giving of notice or
both) under any Contract to which the Company or ARA is a party, including
without limitation any Material Contract, (iii) result in the imposition of any
Encumbrance against any asset or properties of the Company or ARA, (iv) require
any consent, waiver, authorization or approval of, or the making of any filing

of California and as required under the Hart-Scott-Rodino Act) or (v) violate
any Law or Order except with respect to clause (ii), (iii) or (iv) of this
Section 3.2(g), for any such matters that would not reasonably be expected,
singly or in the aggregate, to have a Material Adverse Effect.

                  (h) TAX AND OTHER RETURNS AND REPORTS. Each of the Company and
ARA has timely filed or will file (or, where permitted or required, its
respective direct or indirect parents have timely filed or will file) all
material Tax Returns required to be filed and have paid (or will pay) all Taxes
shown thereon as owing for all taxable periods ending on or before the Closing
Date (a "Pre-Closing Period"). As of the Closing Date, each of the Company and
ARA shall have made payments of estimated taxes as required by Law (taking into
account the tax effects of the transactions contemplated hereby) for (i) the
pre-closing portion of the Straddle Period (as defined in and determined under
Section 4.8(a)), and (ii) taxable periods ending on or prior to the Closing Date
but for which a Tax Return is not yet due. Adequate accruals and reserves have
been provided in the books and records of the Company and ARA, and, to the
extent required by GAAP in the Audited Financial Statements referred to in
Section 3.2(c) above or delivered or to be delivered to Buyer, for all Taxes
whether or not due and payable and whether or not disputed. Neither the Company
nor ARA has elected to be treated as a consenting corporation under Section
341(f) of the Code. Section 3.2G of the Disclosure Schedule lists the date or
dates through which the IRS and any other Governmental Entity have examined the
United States federal income Tax Returns and any other Tax Returns of the
Company and ARA. All required Tax Returns, including amendments to date, have
been prepared in good faith and are complete and accurate in all material
respects. Except as set forth on Section 3.2H of the Disclosure Schedule, there
are no deficiencies for Taxes claimed or proposed by any Governmental Entities
that have not yet been fully paid or settled. Except as set forth on Section
3.2H of the Disclosure Schedule, there are no pending audits relating to Taxes
of the Company or ARA or, to the best of the Company's knowledge, threatened
material audits or investigations relating to Taxes of the Company or ARA.
Neither the Company nor ARA has waived any statute of limitations in respect of
Taxes or agreed to any extension of time with respect to a Tax assessment or
deficiency. Neither the Company nor ARA is a party to any Tax allocation or
sharing agreement. Neither the Company nor ARA has been a member of an
Affiliated Group filing a consolidated federal or a combined or unitary State or
Local Tax Return (other than a group the common parent of which was the Company
or Certified Holding Corporation, a Delaware 



                                       24
<PAGE>

corporation). There are no liens for Taxes (other than for current Taxes not yet
due and payable) on the assets of the Company or ARA. None of the assets of the
Company or ARA (i) directly or indirectly secures any debt the interest on which
is tax exempt, (ii) is property that is required to be treated as being owned by
any other person under the applicable tax law, or (iii) is "tax-exempt use
property" for federal income tax purposes. Neither the Company nor ARA has
agreed to make or is required to make any adjustment under Section 481(a) of the
Code by reason of a change in accounting method or otherwise. Neither the
Company nor ARA is obligated to make, as a result of an event connected with the
transaction contemplated by this Agreement, any "excess parachute payment" as
defined in Section 280G of the Code.

                  (i) REAL AND PERSONAL PROPERTY; TITLE TO PROPERTY; LEASES.
Neither the Company nor ARA owns any real property. The Company and ARA have
title to or other right to use, free of Encumbrances, all items of real
property, including fees, leaseholds, easements and all other interests in real
property, and such other assets and properties that are material to the
Business, except for Permitted Encumbrances. All material tangible assets and
properties of the Company and ARA that are used in or intended to be used in the
Business or otherwise used by the Company or ARA or reflected on the Financial
Statements (other than Inventory sold or otherwise disposed of in the ordinary
course of business) are in a good state of maintenance and repair (except for
ordinary wear and tear) and are adequate for the Business. Section 3.2I of the
Disclosure Schedule sets forth each parcel of Leased Real Property. The Company
has made available to the Buyer true and complete copies of each lease for each
parcel of Leased Real Property (the "Leases") and, to the extent in the
possession of the Company or ARA, all the title insurance policies, title
reports, surveys, mortgages, easements, certificates of occupancy, environmental
reports and audits, appraisals, Permits, other title documents relating to the
Leased Real Property. Either the Company or ARA, as the case may be, is in
peaceful and undisturbed possession of all space that it is currently entitled
to possess under such Lease and no rights adverse to the rights of the Company
or ARA, to the knowledge of ARA or the Company, have been asserted by any Person
and there are no contractual or legal restrictions that preclude or materially
restrict the ability to use the premises for the purposes for which they are
currently being used. Neither the Company nor ARA has leased or subleased any
parcel or any portion of any parcel of Leased Real Property to any other Person.
Neither the Company nor ARA holds any option, right of first refusal or similar
right to purchase any additional parcel or real property or any portion thereof
or interest therein. All material Leased Real Property held by the Company or
ARA as lessee are held under valid, binding and enforceable leases, and neither
ARA nor the Company has received any written notice of any default under any
such Lease. To the knowledge of the Company and ARA, there are no condemnation
proceedings or eminent domain proceedings of any kind pending or threatened
against the Leased Real Property. To the knowledge of the Company and ARA, there
are no material latent defects or material adverse physical conditions affecting
the Leased Real Property or any of the facilities, buildings, structures,
erections, improvements, fixtures, fixed assets and personalty of a permanent
nature annexed, affixed or attached to, located on or forming part of the Leased
Real Property.

                  (j) INTELLECTUAL PROPERTY. The Company and ARA have rights to
and ownership of all Intellectual Property required for use in connection with
the Business. The Company and ARA have in all material respects performed all
obligations required to be performed by them, and they are not in default in any
material respect under any Contract relating to any Owned Intellectual Property
or Licensed Intellectual Property. Neither the 



                                       25
<PAGE>

Company nor ARA has received any notice to the effect (and is not otherwise
aware) that the Owned Intellectual Property or the Licensed Intellectual
Property or any use by the Company and ARA of any such property conflicts with
or allegedly conflicts with or infringes the rights of any Person. Section 3.2J
of the Disclosure Schedule sets forth a true and complete list and a brief
description, including a complete identification of each patent and patent
application and each registration or application for registration thereof, of
all Owned Intellectual Property and Section 3.2J of the Disclosure Schedule sets
forth a true and complete list and a brief description, including a description
of any license or sublicense thereof, of all Licensed Intellectual Property.
Except as disclosed on Section 3.2J of the Disclosure Schedule, the rights of
the Company or ARA, as the case may be, in or to Owned Intellectual Property do
not conflict with or infringe in any material respect on the rights of any other
Person. Except as disclosed in Section 3.2J of the Disclosure Schedule: (i) all
the Owned Intellectual Property is owned by either the Company or ARA, as the
case may be, free and clear of any Encumbrance and (ii) no Actions have been
made or asserted or are pending (nor, to the best knowledge of the Company, has
any such Action been threatened) against the Company or ARA either (A) based
upon or challenging or seeking to deny or restrict in any material way the use
by the Company or ARA of any of the Owned Intellectual Property or (B) alleging
that any services provided, or products manufactured or sold by the Company or
ARA are being provided, manufactured or sold in violation of any patents or
trademarks, or any other rights of any Person. To the knowledge of the Company,
no Person is using any patents, copyrights, trademarks, service marks, trade
names, trade secrets or similar property that are confusingly similar to the
Owned Intellectual Property or that infringe upon the Owned Intellectual
Property or upon the rights of the Company or ARA therein. Except as disclosed
on Section 3.2J of the Disclosure Schedule, neither of the Company nor ARA has
granted any license or other right to any other Person with respect to the Owned
Intellectual Property.

                  The Company has, or has caused to be, delivered to the Buyer
correct and complete copies of all the licenses and sublicenses for Licensed
Intellectual Property listed in Section 3.2J of the Disclosure Schedule and any
and all ancillary documents pertaining thereto (including, but not limited to,
all amendments, consents and evidence of commencement dates and expiration
dates). With respect to the Licensed Intellectual Property and each of such
licenses and sublicenses:

                  (i)      such license or sublicense, together with all
                           ancillary documents delivered pursuant to the first
                           sentence of this Section 3.2J, is valid and binding
                           and in full force and effect and represents the
                           entire agreement between the respective licensor and
                           licensee with respect to the subject matter of such
                           license or sublicense;

                  (ii)     except as otherwise disclosed on Section 3.2J of the
                           Disclosure Schedule, neither the Company nor ARA has
                           granted to any other Person any rights, adverse or
                           otherwise, under such license or sublicense;

                  (iii)    no Actions have been made or asserted or are pending
                           (nor, to the knowledge of the Company, has any such
                           Action been threatened) against the Company or ARA
                           either (A) based upon or challenging or seeking to
                           deny or restrict the use by the Company or ARA of any
                           of the Licensed 



                                       26
<PAGE>

                           Intellectual Property or (B) alleging that any
                           Licensed Intellectual Property is being licensed,
                           sublicensed or used in violation of any patents or
                           trademarks, or any other rights of any Person; and

                  (iv)     to the knowledge of the Company no Person is using
                           any patents, copyrights, trademarks, service marks,
                           trade names, trade secrets or similar property that
                           are confusingly similar to the Licensed Intellectual
                           Property or that infringe upon the Licensed
                           Intellectual Property or upon the rights of the
                           Company or ARA therein.

Schedule, neither the Company nor ARA has received notification that any
qualifications for the Company's or ARA's products as established by the
Company's or ARA's customers have been revoked or terminated as a result of the

                      (B) Each such plan is qualified in form and operation 
         under Section 401(a) of the Code and each trust under each such plan 
         is exempt from tax under Section 501(a) of the Code. No event has 
         occurred that will or, to the knowledge of the Company, could give 
         rise to disqualification or loss of tax-exempt status of any such 
         plan or trust under such sections. No event has occurred that will 
         or, to the knowledge of the Company, could subject any such plans to 
         tax under Section 511 of the Code. To the knowledge of the Company, 
         no non-exempt prohibited transaction (within the meaning of Section 
         4975 of the Code) or non-exempt party-in-interest transaction 
         (within the meaning of Section 406 of ERISA) has occurred with 
         respect to any such plan and none of the Company, ARA or any 
         Employee Plan fiduciary has otherwise violated the provisions of 
         Part 4 of Title I, Subtitle B of ERISA.

                      (iii) Title IV Plan. No Employee Plan listed in Section
3.2R of the Disclosure Schedule is a plan subject to Title IV of ERISA. None of
the Company, ARA or any ERISA Affiliate has, within the last six years, (A)
maintained any employee benefit plan which has been subject to Title IV of
ERISA; or (B) maintained, administered or contributed to any multiemployer plan
as defined in Section 4001(a)(3) of ERISA. Neither the Company nor ARA has any
liability with respect to any employee benefit plan sponsored by any current or
former ERISA Affiliate (other than the Company or ARA).

                      (iv) Health Plans. All group health plans of the Company
and ARA and any trade or business (whether or not incorporated) that is a member
of a group of which Company is a member and which is under common control within
the meaning of Section 414(b), (c), (m) and (o) of the Code ("ERISA Affiliates")
have been operated in material compliance with the group health plan
continuation coverage requirements of Section 4980B of the Code to the extent
such requirements are applicable. Neither Company nor ARA provides health care
or any other non-pension benefits to any employees after their employment is
terminated, other than as required by part 6 of subtitle B of Title I of ERISA
or Section 4980B of the Code or benefits that continue for a brief period of
time after termination of employment (for example, for the balance of the month
in which an employee terminates), or has ever promised to provide any such
post-termination welfare benefits.

                      (v) Fines and Penalties. There has been no act or omission
by the Company or ARA that has given rise to or, to the knowledge of the
Company, may give rise to fines, penalties, taxes, or related charges under

                      (vi) Deductibility of Payments; No Acceleration or
Creation of Rights. There is no contract, agreement, plan or arrangement
covering any employee or former employee of the Company or ARA that,
individually or collectively, provides for the payments by the Company or ARA of
any amount (A) that is not deductible under Section 162(a)(1) or 404 of the Code
or (B) that is an "excess parachute payment" pursuant to Section 280G of the
Code. Except for the Success Bonuses and as otherwise set forth on Section 3.2R
of the Disclosure Schedule, neither the execution and delivery of this Agreement
by the Company and ARA nor the consummation of the transactions contemplated
hereby will result in the acceleration or creation of any rights of any person
to benefits under any Employee Plan (including, without limitation, the
acceleration of the vesting or exercisability of any stock options or warrants,
the 


                                       31

acceleration of the vesting of any restricted stock, the acceleration of the
accrual or vesting of any benefits under any pension plan or the acceleration or
creation of any rights under any severance, parachute or change in control
agreement).

                      (vii) The current value of assets held in the trust
maintained in connection with that certain Deferred Compensation Plan and Trust
Agreement dated as of March 2, 1992 by and among ZMP, Inc., Gene Schiappa (as
trustee) and Charles A. Collins, as amended from time to time (the "Deferred
Compensation Plan"), is not less than the amount of liabilities accumulated
under the Deferred Compensation Plan.

                  (s) INSURANCE. Section 3.2S of the Disclosure Schedule lists
all insurance policies and bonds that are maintained by the Business. All such
policies and bonds that are material to the Business are in full force and
effect and protect the Company and ARA against such losses and risks as is
consistent with industry practice. Neither the Company nor ARA has received any
notice of any material increase in premiums with respect to, or cancellations or
non-renewal of, any of such policies. Neither the Company nor ARA is in default
in any material respect under any such policy or bond.

                  (t) NO BROKERS OR FINDERS. Other than fees to be paid to
Bowles Hollowell Conner & Co. (which fees are to be paid from the Purchase
Price), no agent, broker, finder, or investment or commercial banker, or other
Person or firm engaged by or acting on behalf of the Company or ARA in
connection with the negotiation, execution or performance of this Agreement or
the transactions contemplated by this Agreement, is or will be entitled to any
broker's or finder's or similar fee or other commission as a result of this
Agreement or such transactions.

                  (u) ABSENCE OF CERTAIN ARRANGEMENTS. Neither the Company nor
ARA, and to the Company's or ARA's knowledge no director, officer, agent, or
employee of the Company or ARA or any other Person on behalf of the Company or
ARA, has directly or indirectly (a) made any contribution, gift, bribe, rebate,
payoff, influence payment, kickback, or other payment to any Person, private or
public, regardless of form, whether in money, property, or services (i) to
obtain favorable treatment in securing business, (ii) to pay for favorable
treatment for business secured, or (iii) to obtain special concessions or for
special concessions already obtained, for or in respect of the Company or ARA,
(b) established or maintained any fund or asset that has not been recorded in
the books and records of the Company of ARA.

                  (v) CUSTOMERS AND SUPPLIERS. Section 3.2V of the Disclosure
Schedule sets forth a true and correct list of (a) the names and addresses of
the 15 largest customers of ARA in terms of sales during each of the two fiscal
years ended June 26, 1998 and 1997 and the seven months ended January 22, 1999,
setting forth the total sales to each such customer during such period and (b)
the names and addresses of the 10 largest suppliers of ARA in terms of purchases
during each of the fiscal years ended June 26, 1998 and 1997 and the seven
months ended January 22, 1999, setting forth for each such supplier the total
purchases from each such supplier during such period. Except as set forth on
Section 3.2V of the Disclosure Schedule, neither the Company nor ARA has
received notice from any such customers or suppliers to the effect that there
will be any price increases in ARA's inputs or price decreases in ARA's outputs.
There has 


                                       32
<PAGE>

not been any material adverse change in the business relationship of the Company
with any customer or supplier named on Section 3.2V of the Disclosure Schedule
since June 26, 1998.

                  (w) YEAR 2000 ISSUES. The Company and its Subsidiaries have
developed a plan which, if successfully implemented, will to their knowledge
enable all of their computer systems to process and provide accurate results
using data having date ranges spanning the twentieth and twenty-first centuries.
Without limiting the foregoing, if successfully implemented such plan will to
the knowledge of the Company and its Subsidiaries, cause such computer systems
to (i) manage and manipulate data abnormalities related to such dates; (ii)
manage and manipulate data involving all dates from such centuries without
inaccurate results related to such dates; and (iii) have user interfaces and
data fields formatted to distinguish between dates from the twentieth and
twenty-first centuries. The Company and its Subsidiaries are in the process of
implementing such plan and believe that it can be fully implemented by December
31, 1999 at costs no greater than the costs and reserves relating to "year 2000
issues" shown in the Financial Statements. In addition, the Company and its
Subsidiaries have inquired of all of their material software and hardware
systems vendors and suppliers as to whether such vendors' and suppliers' have
the systems and software necessary to address and accommodate "year 2000
issues", and as to whether such vendors and suppliers computer systems have been
tested and are fully capable of providing accurate results using data having
date ranges spanning the twentieth and twenty-first centuries and, except as set
forth on Section 3.2W of the Disclosure Schedule, each such vendor and supplier
has confirmed the foregoing.

                  (x) REORGANIZATIONS. All reorganizations, restructurings,
mergers, liquidations and dissolutions involving or relating to the Company, ARA
or any former parent corporation of the Company or ARA, (including, without
limitation, Certified Holding Corporation) (collectively, the "FORMER ENTITIES")
complied with all applicable Laws and the organizational documents of such
entities. There are no Liabilities of Certified Holding Corporation that are not

reasonably be expected to be asserted against the Company or ARA. There are no
continuing obligations or liabilities to the Company or ARA in connection with
the Asset Acquisition dated as of July 31, 1986 among ZMP Acquisition
Corporation, Adams Rite Products, Inc., Sabre Industries Inc., MZZM Inc. and
certain other parties named therein.

           customers or suppliers, other than payments under, and in accordance

commercially reasonable efforts to obtain all (and will immediately prepare all
registrations, filings and applications, requests and notices preliminary to
all) Approvals and Permits that may be necessary or which may be reasonably
requested by Buyer to consummate the transactions contemplated by this
Agreement; provided that nothing contained herein shall require either Buyer or
the Company or any of their Affiliates to sell, transfer, divest or otherwise

                  (b) To the extent that Buyer determines in its reasonable
discretion the Approval of a third party with respect to any Material Contract
is required or desirable in connection with the transactions contemplated by
this Agreement, the Company shall use commercially reasonable efforts to obtain
such Approval prior to the Closing Date and in the event that any such Approval
is not obtained, the Company shall reasonably cooperate with Buyer in an effort
to obtain for Buyer the benefits of each such Material Contract. The parties
hereto agree not to take any unreasonable action that will have the effect of
delaying, impairing or impeding the receipt of any Approval or Permit.

                  SECTION 4.3 INVESTIGATION BY BUYER. Subject to applicable
Laws, the Company shall cause ARA to authorize and permit Buyer and its

reasonable notice and in such manner as will not unreasonably interfere with the
conduct of their respective businesses and as will maintain the confidentiality
of this Agreement and the transactions contemplated hereby, to all of the
Company's and ARA's properties, books, records, operating instructions and
procedures, Tax Returns and all other information with respect to the Business

                  SECTION 4.5 SHAREHOLDERS' CONSENT. The Board of Directors of
the Company shall, in accordance with applicable Law, either (i) duly call, give
notice of, convene and hold a special meeting of the shareholders of the Company

satisfactory to Buyer and which complies with all applicable Laws and the
Company's Articles and Incorporation and Bylaws) in lieu of a meeting as soon as
practicable for the purpose of considering and taking action upon this
Agreement. The Company shall take all appropriate action in accordance with all
applicable Laws and the Company's Article of Incorporation and Bylaws (a) to

                  SECTION 4.6 NOTIFICATION OF CERTAIN MATTERS. The Company shall
give prompt notice to Buyer, and Buyer shall give prompt notice to the Company,
of (i) the occurrence, or failure to occur, of any event or fact that would be
likely to cause any representation or warranty made by such party contained in
this Agreement to be untrue in any material respect at any time from the date of
this Agreement to the Closing Date, (ii) any failure of Buyer, Acquisition or
the Company, as the case may be, to comply with or satisfy, in any material
respect, any covenant, condition or agreement to be complied with or satisfied
by it under this Agreement, and (iii) any fact, condition, event or occurrence
that would be likely to prevent any condition to the obligations of the parties
set forth in Article V to be satisfied. Such notice shall provide a reasonably
detailed description of the relevant circumstances and shall include the amount
which the party providing the notice believes, based on the facts actually known
by it, would be payable by the other party pursuant to the indemnification
provides hereof. No such notification shall affect the representations or
warranties of the parties or the conditions to their respective obligations
hereunder.

                  SECTION 4.7 PREPARATION OF TAX RETURNS FOR PRE-CLOSING
PERIODS. The Shareholders' Representative shall prepare and timely file, or
cause to be prepared and timely filed, all Tax Returns required to be filed by
the Company and ARA for any Pre-Closing Period. In the case of any Tax Return of
the Company or ARA for any Pre-Closing Period, Buyer shall (i) cause an officer
of the Company or ARA, as the case may be, to sign such Tax Return, or (ii) duly
and lawfully appoint a Person designated by the Shareholders' Representative as
an officer of the Company or ARA, as the case may be, for purposes of signing
such Tax Return. Shareholders' Representative shall provide to Buyer a copy of
any Tax Return for a Pre-Closing Period no later than 30 days before the due
date (including extensions) for filing such Tax Return for Buyer's review and
consent, which consent shall not unreasonably be withheld (provided, however,
that any position consistent with past practice shall be reasonable for these
purposes).

                  SECTION 4.8 PREPARATION OF TAX RETURNS FOR STRADDLE PERIODS.

                  (a) Buyer shall prepare and timely file, or cause to be
prepared and timely filed, all Tax Returns required to be filed by the Company
and ARA for any Straddle Period. 


                                       36
<PAGE>

With respect to each Tax Return filed with respect to a Straddle Period, Buyer
will provide the Shareholders' Representative with a statement (each, a
"Straddle Period Statement") setting forth (i) Buyer's calculation of the Tax
liability of the Company and ARA allocable to the Deemed Pre-Closing Period (the
"Straddle Period Liability"), and (ii) a copy of the Tax Return to be filed with
respect to such Straddle Period. Buyer shall deliver such Straddle Period
Statement to the Shareholders' Representative no later than 30 days before the
due date (including extensions) for filing such Tax Return. The term "Straddle
Period" means any taxable period of the Company or ARA that begins before the
Closing Date and ends after the Closing Date. Items of income, gain, loss,
deduction, and credit for any Straddle Period attributable to the period of time
on or before the Closing Date shall be allocated to a deemed Pre-Closing Period
that ends on the Closing Date (the "Deemed Pre-Closing Period") using an interim
closing-of-the-books method, assuming that the Deemed Pre-Closing Period ended
as of the close of business on the Closing Date. In the case of any Taxes that
are imposed on a periodic basis (other than Taxes based upon or related to
income or receipts), and are payable for a Straddle Period, the portion of such
Tax which relates to the Deemed Pre-Closing period shall be deemed to be the
amount of such Tax for the entire taxable period multiplied by a fraction the
numerator of which is the number of days in the Deemed Pre-Closing Period and
the denominator of which is the number of days in the entire taxable period.

                  (b) Within 20 days of receipt of such Straddle Period
Statement, the Shareholders' Representative shall, in a written notice to the
Buyer, either accept the Straddle Period Statement or describe in reasonable
detail any proposed adjustment to any item of income, gain, loss, deduction, or
credit on the Straddle Period Statement. Buyer and the Shareholders'
Representative shall negotiate in good faith to resolve any disputes over any
proposed adjustments to the Straddle Period Statement, provided that if any such
dispute is not resolved within 10 days after the Buyer's receipt of the proposed
adjustments, Buyer and the Shareholders' Representative shall jointly engage
Arthur Andersen LLP or such other mutually acceptable national independent
public accounting firm ("Tax Arbitrator") to resolve such dispute, which
resolution shall be final and binding upon the parties, and not subject to
review or challenge of any kind. The amount of the Straddle Period Liability
shall be determined based on (i) the Straddle Period Statement prepared by the
Buyer, if the Shareholders' Representative proposes no adjustment or proposes an
adjustment but no resolution of the issue is reached between the Shareholders'
Representative and the Buyer before the due date (including extensions) for
filing the relevant Tax Return, or (ii) the Straddle Period Statement as finally
resolved between Shareholders' Representative and the Buyer, if the
Shareholders' Representative proposes an adjustment and the Shareholders'
Representative and the Buyer reach a resolution, or the Tax Arbitrator reaches a
resolution, of the proposed adjustment before the due date (including
extensions) for filing such relevant Tax Return. If any final resolution of the
proposed adjustment reached after the filing of the relevant Tax Return differs
from the Straddle Period Statement filed, then Buyer shall file an amended Tax
Return for such Straddle Period in accordance with the determination of the Tax
Arbitrator. Any fees and expenses related to the engagement of the Tax
Arbitrator shall be borne equally by Buyer, on one hand, and the Selling
Shareholders through a payment out of the Escrow Account on the other. Buyer and
the Shareholders' Representative will jointly instruct the Escrow Agent, in
writing, to make any such payment.

                  SECTION 4.9 TAX CONTROVERSIES.

                  (a) The Shareholders' Representative shall have the right, at
the expense of the Selling Shareholders, to control, manage, and be responsible
for any audit, contest, claim, proceeding or inquiry with respect to Taxes, or
items of income, gain, loss, deduction, and credit of, the Company or ARA (a
"Tax Controversy") for any Pre-Closing Period or Straddle Period, and shall have
the right to settle or contest in their discretion any such Tax Controversy;
provided, however, that if the Tax Controversy reasonably could be expected to
affect the Company's or ARA's liability for Tax in any taxable period ending
after the Closing Date (i) Buyer shall have the right to attend and participate
in, at its own expense, any such Tax Controversy controlled by the Shareholders'
Representative, including the right to review in advance and comment upon all
submissions made in the course of such Tax Controversy, and to be present at all
conferences, meetings or proceedings with any taxing authority, and all
appearances before any court, and (ii) no settlement or any disposition of any
such Tax Controversy shall be made without Buyer's prior written consent, which
shall not be unreasonably withheld.

                  (b) Buyer shall have the right, at its own expense, to
control, manage, and be responsible for any Tax Controversy for any taxable
period ending after the Closing Date (other than Straddle Periods), and shall
have the right settle or contest in their discretion any Tax Controversy;
provided, however, that if the Tax Controversy reasonably could be expected to
affect the Company's or ARA's liability for Tax in any Pre-Closing Period (i)
the Shareholders' Representative shall have the right to attend and participate
in, at the expense of the Selling Shareholders, any such Tax Controversy
controlled by the Buyer, including the right to review in advance and comment
upon all submissions made in the course of such Tax Controversy, and to be
present at all conferences, meetings or proceedings with any taxing authority,
and all appearances before any court, and (ii) no settlement or any disposition
of any such Tax Controversy shall be made without the Shareholders'
Representative's prior written consent, which shall not be unreasonably
withheld.

                  (c) Neither the Escrow Account nor any party hereto shall be
liable for any Tax indemnification if the party to be indemnified did not comply
with the procedures of this Agreement relating to Taxes, but only to the extent
the indemnifying party has been prejudiced by such non-compliance.

                  SECTION 4.10 COOPERATION. After the Closing Date, the
Shareholders' Representative and Buyer will cooperate fully, and will cause
their respective Affiliates to cooperate fully, and will provide assistance as
may reasonably be requested, and cause their respective Affiliates to provide
assistance as may reasonably be requested, in connection with the preparation of
any Tax Return, the conduct of any audit or the defense of any litigation or
other proceeding with respect to any Tax liability of the Company or ARA for any
taxable period and shall retain, or shall cause to be retained, until the
expiration of all applicable statutes of limitation, any records or information
that may be relevant to any such Tax Return or audit.

                  SECTION 4.11 ACCESS TO RECORDS AND INFORMATION. Buyer shall
provide the Shareholders' Representative, and the Shareholders' Representative
shall provide Buyer, with the right, at reasonable times and upon reasonable
notice, to have access to, and to copy and use, 


                                       38

taxable period for which Buyer or the Shareholders' Representative, as the case
may be, is charged with filing responsibility for Tax Returns under this
Agreement or otherwise in connection with the preparation of any Tax Returns,
the conduct of any audits, the defense of any litigation with respect to any Tax
liability, the filing of any claim for a refund of Tax or allowance of any Tax
credit or any judicial or administrative proceedings relating to liability for
Taxes.

                  SECTION 4.12 TAX POSITIONS. Buyer shall not, and shall not
permit the Company or ARA to, unless required by Law (i) make or change any Tax
election, or amend any Tax Return or take any Tax position on any Tax Return, or
(ii) take any action or omit to take any action that in any such case results in
any increased Tax liability of the Company or ARA with respect to any
Pre-Closing Period or any increased Straddle Period Liability.

                  SECTION 4.13 INCOME TAX LIABILITY AND REFUNDS. Any amount of
income Taxes shown as due on any Tax Return for any Pre-Closing Period shall be
timely paid out of the Escrow Account and is hereinafter referred to as a
"Declared Pre-Closing Income Tax Liability." Any income Tax refund due in
respect of any Pre-Closing Periods or Deemed Pre-Closing Periods shall be paid
to the Shareholders' Representative for distribution to the Selling Shareholders
in proportion to their Applicable Percentages. Buyer shall, or shall cause the
Company to, file an amended return or claim for any such refund as requested by
the Shareholders' Representative.

                  SECTION 4.14 NO SOLICITATION OR NEGOTIATION. Between the date
of this Agreement and the earlier of (x) the Closing and (y) the termination of
this Agreement, none of the Company or ARA or any of their respective

any of the foregoing. The Company shall notify the Buyer promptly if any such
proposal or offer, or any inquiry or other contact with any Person with respect
thereto, is made or shall have been received after the date hereof, and shall,
in any such notice to the Buyer, indicate in reasonable detail the identity of

confidentiality or standstill agreement to which the Company or ARA is a party.

                  SECTION 4.15 NOVATION AGREEMENTS. The Company shall use its
commercially reasonable efforts to satisfy all conditions to obtaining novation
agreements with

                  (a) Buyer (who shall pay to the Company $250,000 upon exercise

the transactions contemplated by this Agreement as set forth in Section 5.1 or
5.2.

                  (e) The Company by written notice to Buyer if any event occurs
or condition exists (and cannot be cured on or prior to the Termination Date by
the parties' reasonable best efforts) which would render impossible the
satisfaction of one or more conditions to the obligation of the Company to
consummate the transactions contemplated by this Agreement as set forth in
Section 5.1 or 5.3.

                  SECTION 6.2 EFFECTS OF TERMINATION. In the event of the
termination of this Agreement pursuant to Section 6.1, this Agreement shall
thereafter become void and have no future effect, and no party hereto shall have
any liability to the other parties hereto or their respective stockholders or
directors or officers in respect thereof; provided that the obligations of the
parties contained in Sections 9.8 and 9.12 shall survive any such termination;
and provided further that notwithstanding anything to the contrary contained
herein, a termination under Section 6.1 shall not relieve any party of any
liability for a willful breach of or for any willful

misrepresentation under this Agreement or be deemed to constitute a waiver of
any available remedy (including specific performance if available) for any such
breach or misrepresentation.

                                   ARTICLE VII

                                    INDEMNITY

                  SECTION 7.1 INDEMNIFICATION OF BUYER. From and after the
Closing, Buyer, Surviving Corporation and their respective directors, officers,
employees, Affiliates, agents, advisors, representatives and assigns ("Buyer
Indemnitees") shall be indemnified and held harmless by the holders of ZMP
Common Stock on the date hereof out of funds in the Escrow Account and/or the
Glendale Escrow Account, as the case may be, available therefor, from and
against any and all Losses of any such Person, directly or indirectly, as a
result of, or based upon or arising from (1) any untruth or inaccuracy of any of
the representations or warranties (except to the extent related to Taxes) made
by the Company in Section 3.2 of this Agreement or any of the agreements or
covenants (except to the extent related to Taxes) made by the Company in Article
IV of this Agreement, (2) without duplication, (x) any breach of the covenant to
pay any Declared Pre-Closing Income Tax Liability, (y) all Taxes of the Company
or ARA relating to Pre-Closing Periods and (z) any Straddle Period Liability
(collectively "Tax Losses"), (3) any amounts described in Sections 2.8(a)(iii)
and (iv) hereof which are not paid on the Closing Date from the Purchase Price,
(4) Section 1300 Payments and payments required under Section 2.11 in connection
with or as a result of the existence of Dissenting Shares at the Closing if and
to the extent such Losses or payments exceed the Dissenting Share Amount and (5)
any claims or allegations of third parties against any Indemnified Party of any
violation or non-compliance with or pursuant to any Environmental Law at the
Glendale Facility. Indemnification under Section 7.1(1), (2), (3) and (4) shall
be available solely from the Escrow Account as provided herein. Indemnification
under Section 7.1(5) shall be available solely from the Glendale Escrow Account
and the Escrow Account as provided herein.

                  SECTION 7.2 INDEMNIFICATION BY BUYER. From and after the
Closing, Buyer agrees to indemnify and hold harmless each of the Selling
Shareholders and the directors, officers, employees, Affiliates, agents,
advisors, representatives and assigns of each of the Selling Shareholders
("Seller Indemnitees") from and against any and all Losses of any of any such
Person, directly or indirectly, as a result of, or based upon or arising from
any material breach or nonperformance of any of the representations, warranties,
covenants or agreements made by Buyer or Acquisition in or pursuant to this
Agreement.

                  SECTION 7.3 PROCEDURE.

                  (a) Any party seeking indemnification with respect to any Loss
or potential Loss arising from a claim (an "Indemnifiable Claim") asserted by a
third party (including a notice of Tax audit or request to waive or extend a
statute of limitations applicable to any Tax) shall give written notice to the
party required to provide indemnity hereunder (the "Indemnifying Party").
Written notice to the Indemnifying Party of the existence of a third-party
Indemnifiable Claim shall be given by the Indemnified Party within 30 days after
its receipt of a written assertion of liability from the third party, including
in the case of tax matters, written notice of any tax audit that might result in
such a claim. The failure of any Indemnified Party to give 


                                       44
<PAGE>

timely notice hereunder shall not affect rights to indemnification hereunder,
except and only to the extent that the Indemnifying Party demonstrates actual
damage caused by such failure.

                  (b) If any claim, demand or liability is asserted by any third
party against any Person entitled to indemnification hereunder (the "Indemnified
Party"), the Indemnifying Party shall defend any actions or proceedings brought
against the Indemnified Party in respect of matters embraced by the indemnity.
If, after 10 business days following a written request by the Indemnified Party
to defend any action or proceeding, the Indemnifying Party neglects to defend
the Indemnified Party, the Indemnified Party may defend, compromise or settle
the claim on behalf of and for the account and risk of the Indemnifying Party,
who shall be bound by the result. In all cases, the party without the right to
control the defense of the Indemnifiable Claim may participate in the defense at
its own expense.

                  (c) Notwithstanding anything in this Section 7.3 to the
contrary except as set forth in Section 7.3(b), neither the Indemnifying Party
nor the Indemnified Party shall, without the written consent of the other Party,
settle or compromise any Indemnifiable Claim or permit a default or consent to
entry of any judgment unless the claimant and such party provide to such other
Party an unqualified release from all liability in respect of the Indemnifiable
Claim. Notwithstanding the foregoing, if a settlement offer solely for money
damages is made by the applicable third party claimant, and the Indemnifying
Party notifies the Indemnified Party in writing of the Indemnifying Party's
willingness to accept the settlement offer and, subject to the limitations of
Sections 7.5 and 7.6, pay the amount called for by such offer, and the
Indemnified Party declines to accept such offer, the Indemnified Party may
continue to contest such Indemnifiable Claim, free of any participation by the
Indemnifying Party, and the amount of any ultimate liability with respect to
such Indemnifiable Claim that the Indemnifying Party has an obligation to pay
hereunder shall be limited to the lesser of (A) the amount of the settlement
offer that the Indemnified Party declined to accept plus the Losses of the
Indemnified Party relating to such Indemnifiable Claim through the date of its
rejection of the settlement offer or (B) the aggregate Losses of the Indemnified
Party with respect to such Indemnifiable Claim. If the Indemnifying Party makes
any payment on any Indemnifiable Claim, the Indemnifying Party shall be
subrogated, to the extent of such payment, to all rights and remedies of the
Indemnified Party to any insurance benefits or other claims of the Indemnified
Party with respect to such Indemnifiable Claim.

                  SECTION 7.4 SURVIVAL.

                  (a) Each of the representations, warranties, covenants and
agreements contained in or made pursuant to this Agreement or any other
Transaction Document shall expire on the first anniversary of the Closing,
except that the representations contained in Section 3.2(q) and the covenants
and agreements contained in clauses (2), (3), (4) and (5) of Section 7.1 shall
survive the Closing and shall terminate on the third anniversary of the Closing
(the period from the date hereof until the date of the termination of the
related representation, warranty, covenant or agreement is referred to herein as
the "Survival Period"). Except with respect to any matter as to which a claim
has been asserted by notice to the other party that is pending or unresolved at
the end of the pertinent Survival Period, the parties intend to shorten the
statute of limitations and agree that no claims or causes of action may be
brought against any of the Selling Shareholders, the Company, Acquisition or
Buyer based upon, directly or indirectly, any of the 


                                       45
<PAGE>

representations, warranties, covenants or agreements (including covenants and
agreements to indemnify) contained in or made pursuant to this Agreement or any
other Transaction Document after the expiration of the pertinent Survival Period
or any termination of this Agreement.

                  (b) The indemnifications provided for hereunder shall take
effect upon Closing and shall remain in effect during the relevant Survival
Period. Any matter as to which a claim has been asserted by notice to the other
party that is pending or unresolved at the end of the pertinent Survival Period
shall continue to be covered by this Article VII notwithstanding the expiration
of the Survival Period with respect to such claim or the expiration of any
applicable statute of limitations (which the parties hereby waive) until such
matter is finally terminated or otherwise formally resolved by the parties under
this Agreement or by a court of competent jurisdiction and any amounts payable
hereunder are finally determined and paid. Any written notice delivered by a
party with respect to a claim for indemnification shall set forth with
specificity the basis of the claim and a reasonable estimate of the amount
thereof.

                  SECTION 7.5 LIMITATIONS ON INDEMNIFICATION OF BUYER. In
addition to the other limitations set forth herein, including the limitations
set forth in Sections 7.1 and 7.4, Buyer's right to indemnification pursuant to
this Article VII is subject to the following limitations:

                  (a) No indemnification shall be made unless the aggregate
amount of Losses sustained by Buyer Indemnitees under Sections 7.1(1) and (5)
(such amount, "Buyer Losses") exceeds $250,000 and, in such event,
indemnification shall be made only to the extent Buyer Losses exceed $250,000
(it being understood that any Buyer Losses sustained prior to the expiration of
a Survival Period shall continue to be counted for purposes of this Section
7.5(a) in determining whether Buyer is entitled to indemnification). The
limitation under the first sentence of this Section 7.5(a) shall not apply to
Buyer's right to indemnification pursuant to Section 7.1(2), (3) and (4) (it
being understood that in all such cases, Buyer shall be entitled to seek
indemnity immediately) and any Losses for which the Buyer is indemnified under
such sections shall not count towards determining whether Buyer Losses exceed
$250,000.

                  (b) Notwithstanding anything to the contrary herein, the
parties hereto agree that any amounts payable under or pursuant to this Article
VII (other than pursuant to Section 7.1(5)) to any Buyer Indemnitee or in
respect of any Buyer Losses (including any settlement of any Indemnifiable
Claims in accordance with Section 7.3(c)) will be paid solely out of the Escrow
Account, in accordance with this Agreement and the Escrow Agreement, and none of
the Selling Shareholders will have any obligation to make (or otherwise with
respect to) any such payments other than from the Escrow Account. In addition,
notwithstanding anything to the contrary herein, the parties hereto agree that
any amounts payable or pursuant to Section 7.1(5) to any Buyer Indemnitee or in
respect of Buyer Losses (including any settlement of any Indemnifiable Claims in
accordance with Section 7.3(c)) will be solely out of the Escrow Account and the
Glendale Escrow Account in accordance with this Agreement and the Escrow
Agreement, and none of the Selling Shareholders will have any obligation to make
or otherwise with respect to any such payments other than from the Escrow
Account and the Glendale Escrow Account.


                                       46
<PAGE>

                  (c) The amount of any Buyer Losses shall be reduced by any
amount received by Buyer Indemnitees with respect thereto under any insurance
coverage or for any other party alleged to be responsible therefor. Buyer
Indemnitees shall use commercially reasonable efforts to collect any amounts
available under such insurance coverage and from such other party alleged to
have responsibility. If a Buyer Indemnitee receives an amount under insurance
coverage or from such other party with respect to Buyer Losses at any time
subsequent to any indemnification pursuant to this Section 7.5, then such Buyer
Indemnitee shall promptly reimburse the Escrow Account for any payment made,
including expenses incurred, from the Escrow Account in connection with
providing such indemnification up to such amount received by the Buyer
Indemnitee.

                  SECTION 7.6 LIMITATIONS ON INDEMNIFICATION BY BUYER. In
addition to the other limitations set forth herein, including the limitations
set forth in Sections 7.2 and 7.4, Buyer's obligation to indemnify pursuant to
this Article VII is subject to the following limitations:

                  (a) No indemnification shall be made by Buyer unless the
aggregate amount of Losses claimed by Seller Indemnitees under Section 7.2 (such
amount, "Seller Losses") exceeds $250,000 and, in such event, indemnification
shall be made by the Buyer only to the extent Seller Losses exceed $250,000.

                  (b) The amount of any Seller Losses shall be reduced by any
amount received by Seller Indemnitees with respect thereto under any insurance
coverage or for any other party alleged to be responsible therefor. Seller
Indemnitees shall use best efforts to collect any amounts available under such
insurance coverage and from such other party alleged to have responsibility. If
a Seller Indemnitee receives an amount under insurance coverage or from such
other party with respect to Seller Losses at any time subsequent to any
indemnification provided by Buyer pursuant to this Section 7.6, then such Seller
Indemnitee shall promptly reimburse Buyer for any payment made or expense
incurred by Buyer in connection with providing such indemnification up to such
amount received by the Seller Indemnitee.

                  SECTION 7.7 NO SPECULATIVE DAMAGES. Notwithstanding anything
to the contrary elsewhere in this Agreement, no party (or any of its Affiliates)
shall, in any event, be liable to the other party (or any of its Affiliates) for
any speculative damages or remote consequential damages of such other party (or
any of its Affiliates), including loss of speculative future revenue or income,
or loss of business reputation or opportunity relating to the breach or alleged
breach hereof.

                  SECTION 7.8 EXCLUSIVE REMEDY. The remedies provided for in
this Article VII, as limited by the provisions of this Article VII, shall
constitute the sole and exclusive remedy for any post-Closing claims made for
breach of this Agreement or otherwise in connection with the transactions
contemplated hereby; provided that nothing herein shall extinguish or limit any
claim based on fraud.

                  SECTION 7.9 ADJUSTMENT TO MERGER CONSIDERATION. Any payment
pursuant to this Article VII shall be treated for Tax purposes as an adjustment
to the Merger Consideration.


                                       47
<PAGE>

                  SECTION 7.10 TAX ADJUSTMENTS. Any amounts payable by the
Indemnifying Party to or on behalf of an Indemnified Party in respect of a Loss
shall be adjusted as follows. The Indemnified Party shall reimburse the
Indemnifying Party an amount equal to the present value amount of the net
reduction in any year in the liability for Taxes of the Indemnified Party or any
member of a consolidated or combined tax group of which the Indemnified Party
is, or was at any time, part, which reduction will be realized (either through
the reduction of a Tax liability or the increase of a Tax loss or credit) with
respect to any period after the Closing Date and which reduction would not have
been realized but for the amounts paid (or any audit adjustment or deficiency
with respect thereto, if applicable) in respect of a Loss for which the
Indemnified Party is indemnified by the Indemnifying Party pursuant to this
Agreement, or amounts paid by the Indemnified Party pursuant to this paragraph
(a "Net Tax Benefit"). The present value amount of the Net Tax Benefit shall be
determined by: (i) using a discount rate equal to the mid-term applicable
federal rate (under Section 1274(d) of the Code) in effect on the date by which
the payment subject to the Net Tax Benefit adjustment is due, (ii) discounting
back to the date by which the payment subject to the Net Tax Benefit adjustment
is due and (iii) using reasonable assumptions regarding the date (or dates) on
which such Net Tax Benefit will be realized, which assumptions must be verified
by an independent certified public accountant chosen by the Indemnifying Party
if requested by the Indemnifying Party. Each party agrees to provide the other
party or their designated representatives with assistance and such documents and
records reasonably requested by them that are relevant to their ability to
determine when a Net Tax Benefit will be realized, including but not limited to
copies of Tax Returns, estimated tax payments, schedules, and related supporting
documents. In the event the parties are unable to agree on the amount, the
parties shall engage the Tax Arbitrator to resolve the matter, whose decision
shall be final and binding upon the parties and not subject to review or
challenge of any kind.


                                  ARTICLE VIII

                                     ESCROW

                  SECTION 8.1 ASSERTION OF INDEMNIFIABLE CLAIMS. From time to
time during the pertinent Survival Period, Buyer (on its own behalf or on behalf
of the Company) or its successors or assigns may assert a claim that it or a
Buyer Indemnitee is entitled to indemnification pursuant to Section 7.1 (any
such claim for indemnification under Section 7.1(1), (2), (3) or (4), a "Claim"
and any such claim for indemnification under Section 7.1(5), a "Glendale Claim")
and demand satisfaction thereof out of the Escrow Account and/or the Glendale
Escrow Account by sending a written notice to the Shareholders' Representative.
If the Shareholders' Representative shall receive such notice from Buyer before
any termination of the pertinent Survival Period, the notice shall be deemed to
represent a pending Claim (or Claims) or Glendale Claim (or Claims), as the case
may be. Any such notice of a Claim or a Glendale Claim shall be effective only
if the Shareholders' Representative receives a certificate from an executive
officer of Buyer to the effect that the Buyer Indemnitees are entitled to
indemnification therefor pursuant to Article VII, along with a reasonable
description of the Claim or Glendale Claim, the relevant representations,
warranties, covenants or agreements for the breach of which indemnification is
being sought, the dollar amount thereof, copies of any documentation related
thereto and any other information reasonably requested by Shareholders'
Representative to support such Claim or Glendale Claim.

                  SECTION 8.2 RESOLUTION OF CLAIMS; PAYMENTS. (a) Upon the final
resolution of any Claim and a final determination that any amount is owing in
respect thereof to Buyer, or, in the case of any Claim in respect of any Tax
Losses relating to any Straddle Period Liability or any payment of any Declared
Pre-Closing Income Tax Liability, immediately prior to the due date (including
extensions) for filing the relevant Tax Return, Buyer and the Shareholders'
Representative shall jointly instruct Escrow Agent, in writing, to make the
pertinent payment to Buyer or the relevant taxing authority. Upon the final
resolution of all claims relating to Dissenting Shares, Buyer and the
Shareholders' Representative shall jointly instruct the Escrow Agent, in
writing, to pay the excess of $200,000 over the amount payable to Buyer or the
Surviving Corporation in respect of such claims, if any, to the Selling
Shareholders in proportion to their respective Applicable Percentages. Upon the
final resolution of (x) between the first and the third anniversaries of the
Closing, any Claim other than a Claim relating to a purported untruth or
inaccuracy of the representation contained in Section 3.2(q) or to
indemnification under clauses (2), (3), (4) or (5) of Section 7.1 and (y)
thereafter, any claim, Buyer and the Shareholders' Representative shall jointly
instruct the Escrow Agent, in writing, to pay the excess of the amount reserved
in respect of such Claim over the amount payable to Buyer in respect thereof, if
any, to the Selling Shareholders in proportion to their respective Applicable
Percentages; provided if the aggregate amount in the Escrow Account would be
less than the sum of (1) $1,500,000 and (2) an amount by which $200,000 exceeds
any payments made (A) to Buyer Indemnitees in respect of indemnification under
clause (4) of Section 7.1 plus (B) any payments made to the Shareholders'
Representative under the second sentence of this Section 8.2 after any such
payment is proposed to be made such payment shall be reduced to the extent
necessary to avoid such result.

                  (b) Upon the final resolution of any Glendale Claim, Buyer and
Shareholders' Representative shall jointly instruct Escrow Agent, in writing, to
make the pertinent payment to Buyer from the Glendale Escrow Account and/or the
Escrow Account, as applicable.

                  SECTION 8.3 PERIODIC PAYMENTS FROM THE ESCROW ACCOUNTS.

                  (a) Buyer and the Shareholders' Representative shall, ten days
following the first anniversary of the Closing, jointly instruct Escrow Agent,
in writing, to pay to the Selling Shareholders in proportion to their respective
Applicable Percentages an amount, if any, equal to $1,500,000 minus the sum of
(w) the amount of all pending Claims, (x) the amount of all prior payments out
of the Escrow Account in respect of Claims other than any such pending Claims or
payments in respect of Claims relating to Dissenting Shares, (y) the amount of
all payments made to Buyer pursuant to Sections 2.10 and 2.12 and (z) to the
extent that Buyer has delivered a statement pursuant to Section 2.12 requesting
payment in accordance therewith, the amount of such payment so requested.

                  (b) If on or at any time after the third anniversary of the
Closing the amount on deposit in the Escrow Account exceeds the amount of all
then pending Claims, Buyer and the Shareholders' Representative shall jointly
instruct the Escrow Agent, in writing, to pay to the Selling Shareholders in
proportion to their respective Applicable Percentages, the amount of such
excess.


                                       49
<PAGE>

                  (c) If on or at anytime after the date that is 18 months after
the Closing, the amount on deposit in the Glendale Escrow Account exceeds the
amount of all then pending Glendale Claims to be paid from the Glendale Escrow
Account, Buyer and Shareholders' Representative shall jointly instruct the
Escrow Agent, in writing, to pay to the Selling Shareholders in proportion to
their Applicable Percentages, the amount of such excess.

                  (d) No less frequently than quarterly, Buyer and the
Shareholders' Representative shall jointly instruct the Escrow Agent, in
writing, to pay to the Selling Shareholders in proportion to their respective
Applicable Percentages, 50% of the earnings on amounts on deposit in the Escrow
Account, provided that prior to any such payments all expenses due and owing to
the Escrow Agent shall be paid in full.

                  (e) If the Shareholders' Representative so requests, any
instruction to the Escrow Agent to pay any amount to the Selling Shareholders
may state that a portion thereof should instead be paid to the Shareholders'
Representative to defray the Shareholders' Representative's past or future
out-of-pocket expenses in carrying out its responsibilities hereunder.

                  (f) Whenever the Shareholders Representative and/or the
Selling Shareholders shall be entitled to receive a distribution from the Escrow
Account or the Glendale Escrow Account (other than a distribution of current
earnings) the Escrow Agent shall first pay out of such distribution the amount
of the incremental Success Bonuses due to the persons entitled to receive
Success Bonuses as a result of any such proposed distribution and no amount
shall be paid to any Selling Shareholder unless and until all such incremental
Success Bonuses are so paid.

                  SECTION 8.4 TERMINATION OF THE ESCROW ACCOUNT. When all
pending Claims have been finally resolved and paid as set forth in Section 8.2,
the escrow with respect to the Escrow Account shall terminate; provided,
however, that if at any time prior thereto the amount on deposit in the Escrow
Account shall equal zero, then the escrow shall terminate at such earlier time.

request from the other party all documents (and reproductions thereof) received
by it or its representatives from such other party (and, in the case of

                  SECTION 9.13 REMEDIES; WAIVER. Except to the extent this
Section 9.13 is inconsistent with any other provision in this Agreement
(including without limitation Section 7.8) or applicable Law, all rights and
remedies existing under this Agreement and any related agreements or documents
are cumulative to and not exclusive of, any rights or remedies otherwise
available. No failure on the part of any party to exercise or delay in
exercising any right hereunder shall be deemed a waiver thereof, nor shall any
single or partial exercise preclude any further or other exercise of such or any
other right.

                  SECTION 9.14 ATTORNEY'S FEES. In the event of any Action by
any party arising under or out of, in connection with or in respect of, this
Agreement, the prevailing party shall be entitled to reasonable attorney's fees,
costs and expenses incurred in such Action, unless a court determines that such
fees, costs and expenses should be allocated in a different manner.

                  SECTION 9.15 KNOWLEDGE CONVENTION. Whenever used in this
Agreement or in any schedule, exhibit, certificate or other documents delivered
to any party pursuant to this Agreement or any other Transaction Document, "to
the knowledge of the Company", "to the best knowledge of the Company" and words
or phrases of similar import shall mean the actual knowledge of the employees
listed on Schedule 9.15 hereto, after due inquiry, which shall be satisfied by
any such employee's consultation with senior management, and (ii) "to the
knowledge of the Buyer", "to the best knowledge of the Buyer" and words or
phrases of similar import shall mean the actual knowledge of the executive
officers of the Buyer, after due inquiry, which shall be satisfied by
consultation with senior management.

                  SECTION 9.16 REPRESENTATION BY COUNSEL; INTERPRETATION. The
Company, Acquisition and Buyer each acknowledge that each party to this
Agreement or any other Transaction Document has been represented by counsel in
connection with this Agreement or such other Transaction Document and the
transactions contemplated hereby or thereby. Accordingly, any rule of Law or any
legal decision that would require interpretation of any claimed ambiguities in
this Agreement or such other Transaction Document against the party that drafted
it has no application and is expressly waived. The provisions of this Agreement
and the other Transaction Documents shall be interpreted in a reasonable manner
to effect the intent of the parties hereto. Whenever the words "include",
"includes" or "including" are used in this Agreement or any other Transaction
Document, they shall be deemed to be followed by the words "without limitation."

                  SECTION 9.17 WAIVER OF JURY TRIAL. Each party waives any right
to a trial by jury in any Action to enforce or defend any right under this
Agreement or any other related document and agrees that any Action shall be
tried before a court and not before a jury.

                  SECTION 9.18 SEVERABILITY. If any provision of this Agreement
is determined to be invalid, illegal or unenforceable by any Governmental
Entity, the remaining provisions of this Agreement to the extent permitted by
Law shall remain in full force and effect, unless doing so would result in an
interpretation of this Agreement which is manifestly unjust.

                  SECTION 9.19 APPOINTMENT OF SHAREHOLDERS' REPRESENTATIVE. At
the Effective Time and without any action on the part of any Person, TCW Special
Placements Fund II, a California limited partnership, will be appointed as the
representative (the "Shareholders' 


                                       54
<PAGE>

Representative") of the holders of the ZMP Shares immediately prior to the
Effective Time (and any holder of Dissenting Shares at such time which can later
be treated as ZMP shares as of such time) for the purposes of carrying out the
functions required of the Shareholders' Representative set forth in this
Agreement and the Escrow Agreement. Any action or decision taken by the
Shareholders' Representative shall be binding and conclusive on such holders of
the ZMP Shares, and may be relied upon by Buyer. By accepting the Merger
Consideration, each Selling Shareholder will agree to indemnify and hold
harmless the Shareholders' Representative for any act or failure to act of
Shareholders' Representative taken on behalf of such Person, except for the
Shareholders' Representative's gross negligence or willful misconduct. In the
event that the Shareholders' Representative becomes no longer able to carry out
its functions, a replacement Shareholders' Representative will be appointed if
prior to the Effective Time, by the Board of Directors of the Company, and, if
at or after the Effective Time, by majority vote of the Selling Shareholders
based upon the number of the ZMP Shares held immediately prior to the Effective
Time by each such Person. From time to time the Shareholders' Representative
shall be entitled to withhold from any amounts payable to the Selling
Shareholders such amounts (or estimated amounts) as it deems appropriate to
cover any expenses incurred by or on behalf of any of the Company, the Selling
Shareholders and the Shareholders' Representative related to this Agreement, the
Escrow Agreement or any other Transaction Document.

                  SECTION 9.20 ENTIRE AGREEMENT. This Agreement, the Voting
Agreement and the Escrow Agreement constitute the entire agreement and supersede
all prior agreements and understandings, both written and oral, among the
parties with respect to the subject matter hereof, other than the
Confidentiality Agreement, which shall survive the execution and delivery of
this Agreement.

                                    EXHIBIT A

                          [FORM OF AGREEMENT OF MERGER]

                               AGREEMENT OF MERGER


                  AGREEMENT OF MERGER entered into on ________________, 1999, by
and among ZMP, Inc., a California corporation (the "COMPANY"), TransDigm Inc., a
Delaware corporation ("PARENT"), and ARA Acquisition Corporation, a California
corporation and a wholly-owned subsidiary of Parent ("Acquisition Subsidiary").

                  1. Acquisition Subsidiary, which is a corporation incorporated
           under the General Corporation Law of the State of California, and
           which is sometimes hereinafter referred to as the "DISAPPEARING
           CORPORATION," shall be merged with and into the Company, which is a
           corporation incorporated under the General Corporation Law of the
           State of California, and which is sometimes hereinafter referred to
           as the "SURVIVING CORPORATION."

                  2. The separate existence of the disappearing corporation
shall cease upon the effective date of the merger.

                  3. The surviving corporation shall continue its existence
pursuant to the provisions of the General Corporation Law of the State of
California.

                  4. Upon consummation of the merger, the Articles of
Incorporation of the surviving corporation shall be amended in their entirety to
read as set forth in Exhibit 1 attached hereto.

                  5. Each outstanding share of the common stock of the
disappearing corporation shall, upon the effective date of the merger, be
converted into one share of the common stock of the surviving corporation.

                  6. Each share of the capital stock of the Company issued and
outstanding immediately prior to the effectiveness of the merger (which consists
of 105,435 shares of common stock) shall, upon the effective date of the merger,
be converted into the right to receive $_______ in cash (the "MERGER
CONSIDERATION"). The Merger Consideration is subject to adjustment for payments
of indebtedness for borrowed money, accrued interest thereon, the amount of
success bonuses to be paid to the Company's management, certain transaction
costs and indemnification claims, and for changes in net working capital and the
failure of the Surviving Corporation to enter into a certain contractual
arrangement, as provided in or pursuant to the Agreement and Plan of
Reorganization (the "PLAN OF REORGANIZATION") dated as of [___________], 1999
among Parent, Acquisition Subsidiary, the Company and TCW Special Placements
Fund II, a California limited partnership solely in its capacity as
Shareholders' Representative, and, pursuant to the Plan of Reorganization, a
portion of the Merger Consideration will be held in escrow accounts which will
satisfy adjustments based solely on changes in net working capital, the failure
of the surviving corporation to enter into a certain contractual arrangement and
indemnification claims. A copy of the Plan of Reorganization shall be maintained
at the principal executive offices of the surviving corporation and shall be


                                      A-1
<PAGE>

provided without charge to any shareholder of Parent, the disappearing
corporation or the surviving corporation upon written request therefor.

                  7. The merger shall have the effects set forth in Section 1107
of the General Corporation Law of the State of California.

                  8. The disappearing corporation and the surviving corporation
hereby agree that they will cause to be executed and filed and/or recorded any
document or documents prescribed by the laws of the State of California, and
that they will cause to be performed all necessary acts therein and elsewhere to
effectuate the merger.

                  Escrow Account actually earned and not distributed pursuant to
                  Section 7 hereof shall be reported as income of the Selling
                  Shareholders for tax purposes, and distributed to Selling
                  Shareholders as directed by the Shareholders' Representative
                  and Buyer from time to time and, in any case, within 5 days of
                  the end of such calendar quarter.

                  (c) OTHER PROVISIONS. Escrow Agent may sell or present for
                  redemption any obligations so purchased whenever it shall be
                  necessary in order to provide money to meet payments

<PAGE>

                  Distributions shall be made as promptly as practicable and in
any event within 5 days after receipt of any such instruction, order or ruling
even if Escrow Agent has been advised that an appeal or other relief is being
sought, so long as it has not received actual service of a stay of such order or
ruling pending appeal.

                  SECTION 5. NO TRANSFER OF INTEREST IN ESCROW ACCOUNTS. The
Selling Shareholders may assign or transfer, such Person's interest in the
Escrow Account and the Glendale Escrow Account in whole or in part. Except as
set forth in the immediately preceding sentence, no party hereto may transfer or
assign any of its interest herein of obligations hereunder. The Escrow Account
and the Glendale Escrow Account shall remain subject to this Escrow Agreement
and no assignment or transfer by Selling Shareholders shall in any way affect
any rights Buyer may have in the Escrow Account or the Glendale Escrow Account.

                  SECTION 6. METHOD OF PAYMENT. Any payments to be made
hereunder shall be made immediately by wire transfer in immediately available
funds to the account of such party designated in the written instructions
referred to in Section 4.

                  SECTION 7. EXPENSES. Escrow Agent shall be compensated for
services hereunder from the income on the Escrow Funds in accordance with a fee
letter heretofore delivered to Buyer and Selling Shareholders and shall be
reimbursed for its ordinary out-of-pocket expenses including, but not by way of
limitation, the fees and costs of attorneys or agents that it may find necessary
to engage in performance of its duties hereunder and costs arising from the
defense of any suits in which Escrow Agent is named as a defendant in its
capacity as Escrow Agent. If it shall become necessary that Escrow Agent shall
perform extraordinary services, it shall be entitled to reasonable extra
compensation therefor and to reimbursement for reasonable and necessary
extraordinary out-of-pocket expenses unless such extraordinary service or
expense is occasioned by the neglect or breach of this Escrow Agreement by
Escrow Agent.

                  SECTION 8. NOTICES. Any notice or other communication related
hereto must be given in writing and (a) delivered in person, (b) transmitted by
facsimile, (c) mailed by certified or registered mail, postage prepaid, receipt
requested or (d) overnight delivery service, given to the party at its address
stated on the signature pages of this Agreement or at any other address as the
party may specify for this purpose by notice to the other party. Each such
notice or other communication shall be effective (i) if given by
telecommunication, when transmitted to the applicable number and an appropriate
answerback is received, (ii) if given by mail, three days after such
communication is deposited in the mails with first class postage prepaid,
addressed as aforesaid or (iii) if given by any other means, when actually

                  SECTION 9. LIABILITY OF ESCROW AGENT.

                  (a) Escrow Agent's sole liability hereunder shall be to hold
and invest the Escrow Funds and any moneys or other properties received with
respect thereto, to make payments and distributions therefrom in accordance with
the terms of this Escrow Agreement, to distribute information as provided in
Section 4 hereof and otherwise to discharge its obligations hereunder. Escrow
Agent shall not be liable for any act performed in good faith or in reliance on
any document instrument or statement believed by it to be genuine. Escrow Agent
may act upon 



                                      B-3
<PAGE>

any notice, certificate, instrument, request, paper or other document believed
by it to be genuine or to have been made, sent, signed, prescribed or presented
by the proper person or persons. It shall be under no obligation to institute or
defend any action, suit or legal proceeding in connection herewith, or to take
any other action likely to involve it in expense unless first indemnified to its
satisfaction by the party or parties who desire that it undertake such action.

                  (b) If any dispute should arise with respect to the payment or
ownership or right of possession of the Escrow Account, or any part thereof, at
any time, that cannot be settled under other provisions hereof, Escrow Agent is
authorized to retain in its possession, without liability to anyone, all or any
part of the Escrow Account or the Glendale Escrow Account or the proceeds from
any sale thereof until such dispute shall have been settled either by mutual
agreement between the parties concerned or until otherwise ordered by a court
having jurisdiction over it. In either case Escrow Agent will not release any
assets in the Escrow Account or the Glendale Escrow Account until Buyer has
exhausted its remedies and has no further right of appeal in the courts;
provided, however, if after the expiration of the Escrow Period, Selling
Shareholders have received a certified order or ruling from a court ordering or
instructing Escrow Agent to distribute all or any portion of the Escrow Funds to
Selling Shareholders, and such order or ruling has not been stayed within 30
days of such order or ruling, pending appeal, Escrow Agent may distribute the
amounts so ordered.

                  (c) Buyer and Selling Shareholders jointly and severally agree
to indemnify and hold harmless Escrow Agent from all losses, costs and expenses
that may be incurred as a result of its involvement in any litigation arising
from the performance of its duties hereunder, provided that such losses costs
and expenses shall not have resulted from any action taken or omitted by Escrow
Agent and for which it shall have been adjudged negligent or engaged in
misconduct or have acted in bad faith or willful disregard of its duties. Escrow
Agent may rely upon any instruction by the Shareholders' Representative as to
the interests of Selling Shareholders. Until it receives written notice of any
change, Escrow Agent shall be entitled to rely on the oral instructions of the
Shareholders' Representative. The Shareholders' Representative shall confirm
such instructions in writing as soon as practicable.

                  SECTION 10. RESIGNATION OR REMOVAL OF ESCROW AGENT.

                  (a) Escrow Agent may resign as such following the giving of
thirty days' prior written notice to the other parties hereto. Similarly, Escrow
Agent may be removed and replaced following the giving of thirty days' prior
written notice to Escrow Agent by all of the other parties hereto. In either
event, the duties of Escrow Agent shall terminate thirty days after the date of
such notice (or as of such earlier date as may be mutually agreeable); and
Escrow Agent shall then deliver the balance of the Escrow Account then in its
possession to a successor Escrow Agent as shall be appointed by the other
parties hereto as evidenced by a written notice filed with Escrow Agent.

                  (b) If the other parties hereto are unable to agree upon a
successor or shall have failed to appoint a successor prior to the expiration of
thirty days following the date of notice of resignation or removal, the
then-acting Escrow Agent may petition any court of competent jurisdiction for
the appointment of a successor Escrow Agent or otherwise appropriate relief, and
any such resulting appointment shall be binding upon all of the parties hereto.

                                      B-4
<PAGE>

                  (c) Upon acknowledgement by any successor Escrow Agent of the
receipt of the then remaining balance of Escrow Account, the then-acting Escrow
Agent shall be fully released and relieved of all duties, responsibilities, and
obligations under this Escrow Agreement.

                  SECTION 11. CONTINUANCE OF ESCROW AGREEMENT. This Escrow
Agreement shall be binding upon the parties hereto and their respective
permitted transferees, successors, assigns, legal representatives, heirs and
legatees.

governed by and construed and enforced in accordance with the laws of the State
of California.

any rights of appraisal from the Merger that such Shareholder may have.

                  (g) NO SOLICITATION. Prior to the Termination Date, no
Shareholder shall, in its capacity as such, directly or indirectly (including
through advisors, agents or other intermediaries), solicit (including by way of
furnishing information) or respond to any inquiries or the making of any
proposal by any person or entity (other than Buyer or any Affiliate thereof)
with respect to ZMP that constitutes or could reasonably be expected to lead to
the acquisition of all or any portion of th capital stock of ZMP or ARA or
assets of ZMP or ARA (other than Inventory in the ordinary course of Business)
any business combination with ZMP or ARA or any other extraordinary transaction
involving or otherwise relating to ZMP or ARA. If any Shareholder, in its
capacity as such, receives any such inquiry or proposal, then such Shareholder
shall promptly inform Buyer of the terms and conditions, if any, of such inquiry
or proposal and the identity of the person making it. Each Shareholder, in its
capacity as such, will immediately cease and cause to be terminated any existing
activities, discussions or negotiations with any parties conducted heretofore
with respect to any of the foregoing.

                  (h) Each Shareholder agrees to exercise its "drag along"
rights under the Shareholders Agreement of ZMP dated as of January 27, 1997,
among ZMP and certain parties named therein as Acquisition may reasonably
request.

                  SECTION 2 . TRANSFER OF SUBJECT SHARES. During the term of
this Agreement, Shareholders agree not to (i) offer for sale, sell, transfer
(whether by merger, consolidation, operation of law or otherwise), tender,
pledge, encumber, assign or otherwise dispose of, enforce or permit the
execution of the provisions of any redemption agreement with ZMP or enter into
any contract, option or other arrangement or understanding with respect to or
consent to the offer for sale, sale, transfer (whether by merger, consolidation,
operation of law or otherwise), tender, pledge, encumbrance, assignment or other
disposition of, or exercise any discretionary powers to distribute, any Subject
Shares or any interest therein without the prior written consent of Buyer, (ii)
except as contemplated by this Agreement, grant any proxies or powers of
attorney with respect to any Subject Shares, deposit any Subject Shares into a
voting trust or enter into a voting agreement with respect to any Subject
Shares; or (iii) take any action that would make any representation or warranty
of such Shareholder contained herein untrue or incorrect or have the effect of
preventing or disabling such Shareholder from performing such Shareholder's
obligations under this Agreement.

                  SECTION 3. REPRESENTATIONS AND WARRANTIES OF SHAREHOLDERS.
Each Shareholder, jointly and severally, represents and warrants to Buyer,
subject to the terms, conditions and limitations set forth in the Plan of
Reorganization, as follows:

                                      C-3
<PAGE>


                  (a) EXISTENCE AND POWER. Such Shareholder (1) is a partnership
duly formed, validly existing and in good standing under the laws of the State
of California and (2) has all requisite partnership power and authority to
execute and deliver this Agreement and to perform its obligations hereunder.


                  (b) AUTHORIZATION; CONTRAVENTION. The execution and delivery
by each Shareholder of this Agreement and the performance by it of its
obligations hereunder have, (1) been duly authorized by all necessary action
under such Shareholders organizational documents and (2) do not and will not
conflict with or result in a violation (with or without notice or lapse of time
or both) or give rise to any third party right of termination, cancellation,
material modification or acceleration pursuant to, (A) any provision of its
organizational documents or (B) any loan or credit agreement, note, mortgage,
bond, indenture, lease, benefit plan or other agreement, obligation, instrument,
permit, concession, franchise, license, judgment, order, decree, statute, law,
ordinance, injunction, rule or regulation applicable to such Shareholder, the
Subject Shares or any of such Shareholder's other properties or assets.

                  (c) BINDING EFFECT. This Agreement constitutes, or when
executed and delivered by Shareholders will constitute, a valid and binding
obligation of Shareholders, respectively, enforceable against Shareholders in
accordance with its terms, except as such enforceability may be limited by
bankruptcy, insolvency, reorganization, moratorium and similar laws relating to
or affecting creditors' generally, by general equity principles, (regardless of
whether such enforceability is considered in a proceeding in equity or at law)
or by an implied covenant of good faith and fair dealing.

                  (d) OWNERSHIP. Shareholders are the only beneficial or record
owners of the Subject Shares, free and clear of all Encumbrances other than
those arising hereunder or set forth on Schedule I hereto. The Shareholders do
not have record or beneficial ownership of any ZMP Common Stock other than as
set forth on Schedule 3.2B to the Plan of Reorganization. Shareholders have sole
power of disposition with respect to all of the Subject Shares and sole voting
power with respect to the matters set forth in Section 1 hereof and sole power
to demand appraisal rights, in each case with respect to all of the Subject
Shares with no restrictions on such rights, subject to applicable federal
securities laws and the terms of this Agreement.

                  (e) LITIGATION. There is no action, suit, investigation,
complaint or other proceeding pending against Shareholders, or, to the knowledge
of Shareholders, threatened against Shareholders or any other Person that
restricts in any material respect or prohibits (or, if successful, would
restrict or prohibit) the exercise by any party or beneficiary of its rights
hereunder or the performance by any party of its obligations hereunder.

                  SECTION 4. PROXY.

                  Each Shareholder hereby grants to, and appoints, Buyer and
Douglas Peacock, Chief Executive Officer of Buyer, and Nick Howley, President of
Buyer, in their respective capacities as officers of Buyer, and any individual
who shall hereafter succeed to any such office of Buyer, each of them
individually, such Shareholder's irrevocable (until the Termination Date) proxy
and attorney-in-fact (with full power of substitution) to vote the Subject
Shares as indicated in Section 1 above. Each Shareholder intends this proxy to
be irrevocable (until the 



                                      C-4
<PAGE>

Termination Date) and coupled with an interest and will take such further action
and execute such other instruments as may be necessary to effectuate the intent
of this proxy and hereby revokes any proxy previously granted by such
Shareholder with respect to such Shareholder's Subject Shares.

                  SECTION 5. MISCELLANEOUS PROVISIONS.

                  (a) NOTICES. Any notice or other communication related hereto
must be given in writing and (a) delivered in person, (b) transmitted by
facsimile, (c) mailed by certified or registered mail, postage prepaid, receipt
requested or (d) overnight delivery service, given to the party at its address
stated on the signature pages of this Agreement or at any other address as the
party may specify for this purpose by notice to the other party. Each such
notice or other communication shall be effective (i) if given by
telecommunication, when transmitted to the applicable number and an appropriate
answerback is received, (ii) if given by mail, three days after such
communication is deposited in the mails with first class postage prepaid,
addressed as aforesaid or (iii) if given by any other means, when actually
received at such address.

                  (b) NO WAIVERS; REMEDIES; SPECIFIC PERFORMANCE.

                  (1) No failure on the part of any party to exercise or delay
         in exercising any right hereunder shall be deemed a waiver of thereof,
         nor shall any single or partial exercise of any right preclude any
         further or other exercise of such or any other right.

                  (2) In view of the uniqueness of the agreements contained
         herein and the transactions contemplated hereby and thereby and the
         fact that Buyer would not have an adequate remedy at law for money
         damages in the event that any obligation hereunder is not performed in
         accordance with its terms, each party to this Agreement therefore
         acknowledges that Buyer shall be entitled to specific enforcement of
         the terms hereof in addition to any other remedy to which Buyer may be
         entitled, at law or in equity.

                  (c) AMENDMENTS, ETC. This Agreement may not be amended, unless
         said amendment shall be (1) in writing and (2) signed and delivered by
         all parties hereto.


                  (d) SUCCESSORS AND ASSIGNS; THIRD PARTY BENEFICIARIES.

                  (1) Neither this Agreement nor any rights or obligations
hereunder are assignable.

                  (2) The provisions of this Agreement shall be binding upon and
inure solely to the benefit of the parties hereto and their respective permitted
heirs, executors, legal representatives, successors and assigns, and no other
person.

                  (e) GOVERNING LAW. This Agreement and all rights, remedies,
liabilities, powers and duties of the parties hereto shall be governed in
accordance with the laws of the State of California without regard to principles
of conflicts of laws. Each party hereby irrevocably submits to and accepts for
itself and its properties, generally and unconditionally, the exclusive

                                      C-5
<PAGE>

jurisdiction of and service of process pursuant to the Laws of the State of
California and the rules of its courts, waives any defense of forum non
conveniens and agrees to be bound by any judgment rendered thereby arising under
or out of in respect of or in connection with this Agreement.

                  (f) SEVERABILITY OF PROVISIONS. If any provision of this
Agreement is determined to be invalid, illegal or unenforceable by any
Governmental Entity, the remaining provisions hereof to the extent permitted by
Law shall nevertheless remain in full force and effect, unless doing so would
result in an interpretation of this Agreement which is manifestly unjust.

                  (g) HEADINGS AND REFERENCES. The descriptive headings of the
Article and Section headings herein are included for convenience only and do not
constitute a part of this Agreement for any other purpose. References to

as "without limitation" or "but not limited to" or words of similar import) is
used with reference thereto, but rather shall be deemed to refer to all other
items or matters that fall within the broadest possible scope of such general
statement, term or matter.

                  (h) ENTIRE AGREEMENT. This Agreement embodies the entire
agreement and understanding of Shareholders and Buyer, and supersedes all prior
agreements and understandings, both written and oral, with respect to the
subject matter hereof.

                  (i) SURVIVAL. Except as otherwise specifically provided

rights of appraisal from the Merger that Shareholder may have.

(including through advisors, agents or other intermediaries), solicit (including

preventing or disabling Shareholder from performing Shareholder's obligations
under this Agreement.

                  SECTION 3. REPRESENTATIONS AND WARRANTIES OF SHAREHOLDER.
Shareholder represents and warrants to Buyer, subject to the terms, conditions
and limitations set forth in the Plan of Reorganization, as follows:

                  (a) CONTRAVENTION. The execution and delivery by Shareholder
of this Agreement and the performance by it of its obligations hereunder do not
and will not conflict with or result in a violation (with or without notice or
lapse of time or both) or give rise to any third party right of termination,
cancellation, material modification or acceleration pursuant to 



                                      D-3
<PAGE>

any loan or credit agreement, note, mortgage, bond, indenture, lease, benefit
plan or other material agreement, obligation, instrument, permit, concession,
franchise, license, judgment, order, decree, statute, law, ordinance,
injunction, rule or regulation applicable to Shareholder, the Subject Shares or
any of Shareholder's other properties or assets.

                  (b) BINDING EFFECT. This Agreement constitutes, or when
executed and delivered by Shareholder will constitute, a valid and binding
obligation of Shareholder enforceable against Shareholder in accordance with its
terms, except as such enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium and similar laws relating to or affecting creditors'
generally, by general equity principles, (regardless of whether such
enforceability is considered in a proceeding i equity or at law) or by an
implied covenant of good faith and fair dealing.

                  (c) OWNERSHIP. Shareholder is the only beneficial or record
owner of the Subject Shares, free and clear of all Encumbrances other than those
arising hereunder or set forth on Schedule I hereto. Shareholder does not have
record or beneficial ownership of any ZMP Common Stock other than as set forth
on Schedule 3.2B to the Plan of Reorganization. Shareholder has sole power of
disposition with respect to all of the Subject Shares and sole voting power with
respect to the matters set forth in Section 1 hereof and sole power to demand
appraisal rights, in each case with respect to all of the Subject Shares with no
restrictions on such rights, subject to applicable federal securities laws and
the terms of this Agreement.

                  (d) LITIGATION. There is no action, suit, investigation,
complaint or other proceeding pending against Shareholder, or, to the knowledge
of Shareholders, threatened against Shareholder or any other Person that
restricts in any material respect or prohibits (or, if successful, would
restrict or prohibit) the exercise by any party or beneficiary of its rights
hereunder or the performance by any party of its obligations hereunder.

                  (e) INDEBTEDNESS. Shareholder acknowledges he owes to the
Company the Collins Note Amount (as defined in the Plan of Reorganization) which
will be repaid in full or canceled as of the Effective Time. In addition,
Shareholder acknowledges that the exercise price of the Collins Option is $39.41
per share.

                  SECTION 4. PROXY.

                  Shareholder hereby grants to, and appoints, Buyer and Douglas
Peacock, Chief Executive Officer of Buyer, and Nick Howley, President of Buyer,
in their respective capacities as officers of Buyer, and any individual who
shall hereafter succeed to any such office of Buyer, each of them individually,
Shareholder's irrevocable (until the Termination Date) proxy and
attorney-in-fact (with full power of substitution) to vote the Subject Shares as
indicated in Section 1 above. Shareholder intends this proxy to be irrevocable
(until the Termination Date) and coupled with an interest and will take such
further action and execute such other instruments as may be necessary to
effectuate the intent of this proxy and hereby revokes any proxy previously
granted by Shareholder with respect to Shareholder's Subject Shares.

                  SECTION 5. WARRANT CANCELLATION.

                                      D-4
<PAGE>

                  Shareholder agrees that, in consideration of the payment to
him of the Merger Consideration with respect to the warrants ("Warrants") owned
by him to purchase 3,260 shares of common stock of ZMP, Inc., upon payment of
the Merger Consideration, all Warrants will be canceled and none of Buyer,
Acquisition, Surviving Corporation nor ZMP will have any further liability or
obligation to the undersigned with respect to the Warrants or any agreement,
understanding or commitment related thereto. Shareholder further agrees that he
will not exercise his Warrants for so long as this Agreement is in effect.

                  SECTION 6. MISCELLANEOUS PROVISIONS.

                  (a) NOTICES. Any notice or other communication related hereto
must be given in writing and (a) delivered in person, (b) transmitted by
facsimile, (c) mailed by certified or registered mail, postage prepaid, receipt
requested or (d) overnight delivery service, given to the party at its address
stated on the signature pages of this Agreement or at any other address as the
party may specify for this purpose by notice to the other party. Each such
notice or other communication shall be effective (i) if given by

                  (b) NO WAIVERS; REMEDIES; SPECIFIC PERFORMANCE.

                  (1) No failure on the part of any party to exercise or delay
in exercising any right hereunder shall be deemed a waiver of thereof, nor shall
any single or partial exercise of any right preclude any further or other
exercise of such or any other right.

                  (2) In view of the uniqueness of the agreements contained
herein and the transactions contemplated hereby and thereby and the fact that
Buyer would not have an adequate remedy at law for money damages in the event
that any obligation hereunder is not performed in accordance with its terms,
each party to this Agreement therefore acknowledges that Buyer shall be entitled
to specific enforcement of the terms hereof in addition to any other remedy to
which Buyer may be entitled, at law or in equity.

                  (c) AMENDMENTS, ETC. This Agreement may not be amended, unless
said amendment shall be (1) in writing and (2) signed and delivered by all
parties hereto.
 
                  (d) SUCCESSORS AND ASSIGNS; THIRD PARTY BENEFICIARIES.

                  (1) Neither this Agreement nor any rights or obligations
hereunder are assignable.

                  (2) The provisions of this Agreement shall be binding upon and
inure solely to the benefit of the parties hereto and their respective permitted
heirs, executors, legal representatives, successors and assigns, and no other
person.

                                      D-5
<PAGE>

                  (e) GOVERNING LAW. This Agreement and all rights, remedies,
liabilities, powers and duties of the parties hereto shall be governed in
accordance with the laws of the State of California without regard to principles
of conflicts of laws. Each party hereby irrevocably submits to and accepts for
itself and its properties, generally and unconditionally, the exclusive
jurisdiction of and service of process pursuant to the Laws of the State of
California and the rules of its courts, waives any defense of forum non
conveniens and agrees to be bound by any judgment rendered thereby arising under
or out of in respect of or in connection with this Agreement.

                  (f) SEVERABILITY OF PROVISIONS. If any provision of this
Agreement is determined to be invalid, illegal or unenforceable by any
Governmental Entity, the remaining provisions hereof to the extent permitted by
Law shall nevertheless remain in full force and effect, unless doing so would
result in an interpretation of this Agreement which is manifestly unjust.

                  (g) HEADINGS AND REFERENCES. The descriptive headings of the
Article and Section headings herein are included for convenience only and do not
constitute a part of this Agreement for any other purpose. References to
parties, express beneficiaries, articles and sections herein are references to

defined in this Agreement may, unless the context otherwise requires, be used in

or matter to the specific items or matters set forth immediately following such
word or to similar items or matters, whether or not nonlimiting language (such
as "without limitation" or "but not limited to" or words of similar import) is
used with reference thereto, but rather shall be deemed to refer to all other
items or matters that fall within the broadest possible scope of such general
statement, term or matter.

                  (h) ENTIRE AGREEMENT. This Agreement embodies the entire
agreement and understanding of Shareholder and Buyer, and supersedes all prior
agreements and understandings, both written and oral, with respect to the
subject matter hereof.

                  (i) SURVIVAL. Except as otherwise specifically provided
herein, each representation, warranty or covenant of a party contained herein
shall remain in full force and effect until the expiration of the pertinent
Survival Period.

                  (j) FURTHER ASSURANCES. The parties hereto each agree to
execute, make, acknowledge, and deliver such instruments, agreements and other
documents as may be reasonably required to effectuate the purposes of this
Agreement and to consummate the transactions contemplated thereby.

                  (k) WAIVER OF JURY TRIAL. Each party waives any right to a
trial by jury in any Action to enforce or defend any right hereunder and agrees
that any Action shall be tried before a court and not before a jury.

                  (l) TERMINATION. Buyer may terminate this Agreement at any

Plan of Reorganization pursuant to Section 6.1 thereof.

                  (m) COUNTERPARTS. This Agreement and any amendment hereto may
be executed in one or more counterparts and by different parties in separate
counterparts, each of which shall be an original, with the same effect as if all
signatures were on the same instrument. All of such counterparts shall
constitute one and the same agreement (or other document) and shall become
effective (unless otherwise provided therein) when one or more counterparts have
been executed by each party and delivered to the other party.

                    TEXT OF OPINION OF COUNSEL TO THE COMPANY


1. Each of ZMP, Inc. ("ZMP") and Adams Rite Aerospace, Inc. ("ARA"), is duly
incorporated, and is validly existing and in good standing under the laws of the
State of California. ZMP has the corporate power to execute and deliver each of
the Agreement and the Agreement of Merger (collectively, the "Agreements") and
to perform its obligations thereunder. Each of ZMP and ARA has corporate power
to own and lease its properties and assets.

2. The execution, delivery and performance of the Agreements have been duly
authorized by all necessary corporate action on the part of ZMP and all
necessary partnership action on the part of the Shareholders' Representative and
the Agreements to which each of them is a party have been duly executed and
delivered by ZMP and the Shareholders' Representative.

3. Each of the Agreements constitutes the legally valid and binding obligation
of ZMP, enforceable against ZMP in accordance with its terms, except as may be
limited by bankruptcy, insolvency, reorganization, moratorium or similar laws
relating to or affecting creditors' rights generally (including, without
limitation, fraudulent conveyance laws) and by general principles of equity,
including, without limitation, concepts of materiality, reasonableness, good
faith and fair dealing and the possible unavailability of specific performance
or injunctive relief, regardless of whether considered in a proceeding in equity
or at law.

4. ZMP's execution and delivery of, and performance of its obligations under the
Agreements on or prior to the date of this opinion do not (i) violate ZMP's or
ARA's Articles of Incorporation and By-laws, (ii) violate, breach, or result in
a default under any existing obligation of or restriction on ZMP or ARA under
any other agreements identified in ZMP's Certificate, or (iii) breach or
otherwise violate any existing obligation of or restriction on ZMP or ARA under
any order, judgment or decree of any California or federal court or governmental
authority binding on ZMP or ARA identified in ZMP's Certificate.

5. The execution and delivery by ZMP and the Shareholders' Representative of,
and performance of their respective obligations under, the Agreements to which
each of them is a party do not violate any California or federal statute, rule
or regulation that we have, in the exercise of customary professional diligence,
recognized as applicable to ZMP, ARA, the Shareholders' Representative or to
transactions of the type contemplated by the Agreements.

6. No order, consent, permit or approval of any California or federal
governmental authority that we have, in the exercise of customary professional
diligence, recognized as applicable to ZMP, ARA, the Shareholders'
Representative or to transactions of the type contemplated by the Agreements is
required on the part of ZMP or the Shareholders' Representative for the
execution and delivery of, and performance of its obligations on or prior to the
date of this opinion under, the Agreements to which each of them is a party,
except for such as have been obtained.

7. Assuming due authorization of the Merger by all necessary corporate action on
the part of Buyer and Acquisition and that Buyer and Acquisition have taken all
action they are required to take, upon the filing of the Articles of Merger by
the Secretary of State of the State of California, 



                                     D-1-1

the Merger will be validly consummated in accordance with the Agreement, the
Agreement of Merger and the General Corporation Law of the State of California.

8. The authorized capital stock of ZMP is as set forth in Section 3.2B of the
Disclosure Schedule. The authorized capital stock of ARA consists of
_____________ shares of common stock. Based solely upon a review of records
certified to us as the stock record books of ZMP and ARA, and without
independent investigation, (i) the number of outstanding shares of ZMP's capital
stock is as set forth in Section 3.2B of the Disclosure Schedule and (ii) there
are 50,000 outstanding shares of ARA common stock, all of which are owned of
record by ZMP. Based solely upon (x) a review of such stock record books of ZMP
and ARA, (y) records certified to us as the minute books of ZMP and ARA and (z)
matters set forth in the ZMP Certificate, and without independent investigation,
the outstanding shares of capital stock of each of ZMP and ARA have been duly
authorized by all necessary corporate action on the part of each of ZMP and ARA,
respectively, and are validly issued, fully paid and nonassessable. Holders of
the capital stock of ZMP and of ARA are not entitled to any preemptive right to
subscribe to any additional shares of their respective capital stock under their
respective Articles of Incorporation or Bylaws.

1. TransDigm, Inc. ("BUYER") has been duly incorporated and is validly existing

2. The execution, delivery and performance of the Agreements have been duly
authorized by all necessary corporate action on the part of Buyer, and the

3. The Agreements constitute the valid and binding obligations of Buyer,

opinions expressed in this paragraph 3 are subject to the following limitations,
qualifications and exceptions: (i) the effect of bankruptcy, insolvency,
reorganization, moratorium or other similar laws now or hereafter in effect
relating to or affecting the rights or remedies of creditors; (ii) the effect of
general principles of equity, whether enforcement is considered in a proceeding
in equity or at law, and the discretion of the court before which any proceeding
therefor may be brought; (iii) the unenforceability under certain circumstances
under law or court decisions of provisions providing for the indemnification of
or contribution to a party with respect to a liability where such
indemnification or contribution is contrary to public policy; and (iv) the
unenforceability of any provision requiring the payment of attorney's fees,

breach or violation of the certificate of incorporation or bylaws of Buyer; (ii)
result in any violation of any applicable federal or California statute, rule or
regulation applicable to Buyer; (iii) require any consent, approval or

us by Buyer as being all of the orders, judgments and decrees that are material
to the financial condition or results of operations of Buyer. No opinion is
expressed in clause (ii) or (iii) of this paragraph 4 as to the application or
contravention of any antifraud laws, antitrust laws or trade regulations. The
opinions set forth in this paragraph 4 are based upon our consideration of only

following limitations, qualifications and exceptions: (i) the effect of
bankruptcy, insolvency, reorganization, moratorium or other similar laws now or
hereafter in effect relating to or affecting the rights or remedies of
creditors; (ii) the effect of general principles of equity, whether enforcement
is considered in a proceeding in equity or at law, and the discretion of the
court before which any proceeding therefor may be brought; (iii) the
unenforceability under certain circumstances under law or court decisions of
provisions providing for the indemnification of or contribution to a party with
respect to liability where such indemnification or contribution is contrary to
public policy; and (iv) the unenforceability of any provision requiring the
payment of attorney's fees, except to the extent that a court determines such
fees to be reasonable.

consummation of the Merger contemplated by the Agreement will (i) result in any
breach or violation of the articles of incorporation or bylaws of Acquisition;

rule or regulation applicable to Acquisition; (iii) require any consent,
approval or authorization, declaration or filing by Acquisition under any
federal or California statute, rule or regulation applicable to Acquisition;

judgments and decrees that are material to the financial condition or results of
operations of Buyer. No opinion is expressed in clause (ii) or (iii) of this

                                    ARTICLE I

                                  SHAREHOLDERS

          Section 1.01. ANNUAL MEETINGS. The annual meeting of the shareholders
of the Corporation for the election of directors and for the transaction of such
other business as properly may come before such meeting shall be held at such
place, either within or without the State of California, and at such date and
hour, as may be fixed from time to time by resolution of the Board of Directors
and set forth in the notice or waiver of notice of the meeting.

          Section 1.02. SPECIAL MEETINGS. Special meetings of the shareholders
may be called at any time by the President (or, in the event of his absence or
disability, by any Vice President), or by the Board of Directors. A special
meeting shall be called by the President (or, in the event of his absence or
disability, by any Vice President), or by the Secretary, immediately upon
receipt of a written request therefor by shareholders holding in the aggregate
not less than 10% of the outstanding shares of the Corporation at the time
entitled to vote at any meeting of the shareholders. If such officers or the
Board of Directors shall fail to call such meeting within 20 days after receipt
of such request, any shareholder executing such request may call such meeting to
be held at a time requested by the person or persons calling the meeting, not
less than 35 nor more than 60 days after the receipt of the request. Such
special meetings of the shareholders shall be held at such places, within or
without the State of California, as shall be specified in the respective notices
or waivers of notice thereof.

          Section 1.03. NOTICE OF MEETINGS; WAIVER. The Secretary or any
Assistant Secretary shall cause written notice of the place, date and hour of
each meeting of the shareholders, and, (i) in the case of a special meeting, the
general nature of the business to be transacted, or (ii) in the case of the
annual meeting those matters which the Board of Directors, at the time of giving
the notice, intends to present for action by the shareholders, to be given
personally or by first-class mail, not less than ten nor more than sixty days
prior to the meeting, to each shareholder of record entitled to vote at such
meeting. The notice of any meeting at which directors are to be elected shall
include the name of any nominee or nominees which, at the time of the notice,
management intends to present for election.

          If action is proposed to be taken at any meeting for approval of (i) a
contract or transaction in which a director has a direct or indirect financial
interest, pursuant to Section 310 of the Corporations Code of California, (ii)
an amendment of the articles of incorporation, pursuant to Section 902 of such
Code, (iii) a reorganization of the corporation, pursuant to Section 1201 of
such Code, (iv) a voluntary dissolution of the corporation, pursuant to Section

<PAGE>

1900 of such Code, or (v) a distribution in dissolution other than in accordance
with the rights of outstanding preferred shares pursuant to Section 2007 of such
Code, the notice shall also state the general nature of such proposal.

          If such notice is mailed, it shall be deemed to have been given to a
shareholder when deposited in the United States mail, postage prepaid, directed
to the shareholder at his address as it appears on the record of shareholders of
the Corporation, or, if he shall have filed with the Secretary of the
Corporation a written request that notices to him be mailed to some other
address, then directed to him at such other address. If no such address appears
on the corporation's books or has been so given, notice shall be deemed to have
been given if sent by first-class mail or telegraphic or other written
communication to the corporation's principal executive office, or if published
at least once in a newspaper of general circulation in the county where such
office is located.

          If any notice addressed to a shareholder at the address of such
shareholder appearing on the books of the corporation is returned to the
corporation by the United States Postal Service marked to indicate that the
United States Postal Service is unable to deliver the notice to the shareholder
at such address, all future notices or reports shall be deemed to have been duly
given without further mailing if the same shall be available to the shareholder
upon written demand of the shareholder at the principal executive office of the
corporation for a period of one year from the date of the giving of such notice.
Such further notice shall be given as may be required by law.

          No notice of any meeting of shareholders need be given to any
shareholder who submits a signed waiver of notice, whether before or after the
meeting. Neither the business to be transacted at, nor the purpose of, any
regular or special meeting of the shareholders need be specified in a written
waiver of notice. The attendance of any shareholder at a meeting of shareholders
shall constitute a waiver of notice of such meeting, except when the shareholder
attends a meeting for the express purpose of objecting, at the beginning of the
meeting, to the transaction of any business on the ground that the meeting is
not lawfully called or convened.

          An affidavit of the mailing or other means of giving any notice of any
shareholders' meeting shall be executed by the Secretary, Assistant Secretary or
any transfer agent of the corporation giving such notice, and shall be filed and
maintained in the minute book of the corporation.

          Section 1.04. QUORUM. Except as otherwise required by law or by the
Certificate of Incorporation, the presence in person or by proxy of the holders
of record of a majority of the shares entitled to vote at a meeting of
shareholders shall constitute a quorum for the transaction of business at such
meeting.

          Section 1.05. VOTING. If, pursuant to Section 5.05 of these By-Laws, a
record date has been fixed, every holder of record of shares entitled to vote at
a meeting of shareholders 

                                       2
<PAGE>

shall be entitled to one vote for each share outstanding in his name on the
books of the Corporation at the close of business on such record date. If no
record date has been fixed, then every holder of record of shares entitled to
vote at a meeting of shareholders shall be entitled to one vote for each share
of stock standing in his name on the books of the Corporation at the close of
business on the day next preceding the day on which notice of the meeting is
given, or, if notice is waived, at the close of business on the day next
preceding the day on which the meeting is held.

          Any shareholder entitled to vote on any matter (other than the
election of directors) may vote part of the shares in favor of the proposal and
refrain from voting the remaining shares or vote them against the proposal, but,
if the shareholder fails to specify the number of shares such shareholder is
voting affirmatively, it will be conclusively presumed that the shareholder's
approving vote is with respect to all shares such shareholder is entitled to
vote. If a quorum is present, the affirmative vote of the majority of the shares
represented at the meeting and voting on any matter (other than the election of
directors), provided that the shares voting affirmatively must also constitute
at least a majority of the required quorum, shall be the act of the
shareholders, unless the vote of a greater number or voting by classes is
required by the California General Corporation Law or the articles of
incorporation.

          At a shareholders' meeting involving the election of directors, no
shareholder shall be entitled to cumulate votes (i.e., cast for any candidate a
number of votes greater than the number of the shareholder's shares) unless such
candidate or candidates' names have been placed in nomination prior to
commencement of the voting and a shareholder has given notice prior to
commencement of the voting of the shareholder's intention to cumulate votes. If
any shareholder has given such notice, then every shareholder entitled to vote
may cumulate such shareholder's votes for candidates in nomination and give one
candidate a number of votes equal to the number of directors to be elected
multiplied by the number of votes to which such shareholder's shares are
entitled, or distribute the shareholder's votes on the same principle among any
or all of the candidates, as the shareholder thinks fit. The candidates
receiving the highest number of votes, up to the number of directors to be
elected, shall be elected.

          Section 1.06. VOTING BY BALLOT. No vote of the shareholders need be
taken by ballot unless required by law (except that all elections for directors
must be by ballot upon demand by a shareholder at the meeting and before the
voting begins). Any vote which need not be taken by ballot may be conducted by
voice vote or in any manner approved by the meeting.

          Section 1.07. ADJOURNMENT. If a quorum is not present at any meeting
of the shareholders, the shareholders present in person or by proxy shall have
the power to adjourn any such meeting from time to time until a quorum is
present. Notice of any adjourned meeting of the shareholders of the Corporation
need not be given if the place, date and hour thereof are announced at the
meeting at which the adjournment is taken, provided, however, that if the
adjournment is for more than thirty days, or if after the adjournment a new
record date for the adjourned meeting is fixed pursuant to Section 5.05 of these
By-Laws, a notice of the adjourned 

                                       3
<PAGE>

meeting, conforming to the requirements of Section 1.03 hereof, shall be given
to each shareholder of record entitled to vote at such meeting. At any adjourned
meeting at which a quorum is present, any business may be transacted that might
have been transacted on the original date of the meeting.

          Section 1.08. PROXIES. Any shareholder entitled to vote at any meeting
of the shareholders or to express consent to or dissent from corporate action
without a meeting may authorize another person or persons to vote at any such
meeting and express such consent or dissent for him by proxy. A shareholder may
authorize a valid proxy by executing a written instrument signed by such
shareholder, or by causing his or her signature to be affixed to such writing by
any reasonable means including, but not limited to, by facsimile signature, or
by transmitting or authorizing the transmission of a telegram, cablegram or
other means of electronic transmission to the person designated as the holder of
the proxy, a proxy solicitation firm or a like authorized agent. A proxy must be
filed with the Secretary of the corporation. No such proxy shall be voted or
acted upon after the expiration of eleven months from the date of such proxy,
unless such proxy provides for a longer period. Every proxy shall be revocable
at the pleasure of the shareholder executing it, except in those cases where
applicable law provides that a proxy shall be irrevocable. A shareholder may
revoke any proxy which is not irrevocable by attending the meeting and voting in
person or by filing an instrument in writing revoking the proxy or by filing
another duly executed proxy bearing a later date with the Secretary. Proxies by
telegram, cablegram or other electronic transmission must either set forth or be
submitted with information from which it can be determined that the telegram,
cablegram or other electronic transmission was authorized by the shareholder.
Any copy, facsimile telecommunication or other reliable reproduction of a
writing or transmission created pursuant to this section may be substituted or
used in lieu of the original writing or transmission for any and all purposes
for which the original writing or transmission could be used, provided that such
copy, facsimile telecommunication or other reproduction shall be a complete
reproduction of the entire original writing or transmission.

          Section 1.09. ORGANIZATION; PROCEDURE. At every meeting of
shareholders the presiding officer shall be the President or, in the event of
his absence or disability, a presiding officer chosen by a majority of the
shareholders present in person or by proxy. The Secretary, or in the event of
his absence or disability, the Assistant Secretary, if any, or if there be no
Assistant Secretary, in the absence of the Secretary, an appointee of the
presiding officer, shall act as Secretary of the meeting. The order of business
and all other matters of procedure at every meeting of shareholders may be
determined by such presiding officer.

          Section 1.10. CONSENT OF SHAREHOLDERS IN LIEU OF MEETING. To the
fullest extent permitted by law, whenever the vote of shareholders at a meeting
thereof is required or permitted to be taken for or in connection with any
corporate action, 

                                       4
<PAGE>

such action may be taken without a meeting, without prior notice and without a
vote of shareholders, if a consent or consents in writing, setting forth the
action so taken, shall be signed by the holders of outstanding stock having not
less than the minimum number of votes that would be necessary to authorize or
take such action at a meeting at which all shares entitled to vote thereon were
present and voted and shall be filed with the Secretary of the corporation and
shall be maintained in the corporate records. In the case of election of
directors, such consent shall be effective only if signed by the holders of all
outstanding shares entitled to vote for the election of directors; provided,
however, that a director may be elected at any time to fill a vacancy not
created by removal and not filled by the directors by the written consent of the
holders of a majority of the outstanding shares entitled to vote for the
election of directors.

          Every written consent shall bear the date of signature of each
shareholder or member who signs the consent and no written consent shall be
effective to take the corporate action referred to therein unless, within sixty
days of the earliest dated consent delivered in the manner required by law to
the Corporation, written consents signed by a sufficient number of holders or
members to take action are delivered to the Corporation. Any shareholder giving
a written consent, or the shareholder's proxy holders, or a transferee of the
shares or a personal representative of the shareholder or their respective proxy
holder, may revoke the consent by a writing received by the Secretary of the
corporation prior to the time that written consents of the number of shares
required to authorize the proposed action have been filed with the Secretary.

Directors, subject to the provisions of Section 310 of the Corporations Code of
California (approval of contracts or transactions in which a director has a
direct or indirect material financial interest), Section 311 (appointment of
committees), and Section 317 (e) (indemnification of directors). A meeting at

Board of Directors may participate in a meeting of the Board of Directors by
means of conference telephone or similar communications equipment by means of

time, either for or without cause, upon the affirmative vote of the holders of a
majority of the outstanding shares of stock of the Corporation entitled to vote
for the election of such Director, cast at a special meeting of shareholders
called for the purpose, or by court order. Any vacancy in the Board of Directors
caused by any such removal may be filled at such meeting by the shareholders
entitled to vote for the election of the Director so removed. If such
shareholders do not fill such vacancy at such meeting (or in the written
instrument effecting such removal, if such removal was effected by consent
without a meeting), such vacancy may be filled in the manner provided in Section
2.13 of these By-Laws.

          Section 2.13. VACANCIES AND NEWLY CREATED DIRECTORSHIPS. If any

<PAGE>

to act, and such vacancies and newly created directorships may be filled by a
majority of the Directors then in office, although less than a quorum. A
Director elected to fill a vacancy or a newly created directorship shall hold

the matters the member reasonably believes are within such other person's
professional or expert competence and who has been selected with reasonable care
by or on behalf of the Corporation.

Any action required or permitted to be taken at any meeting of any such
Committee may be taken without a meeting, if all members of such Committee shall
consent to such action in writing and such writing or writings are filed with
the minutes of the proceedings of the Committee. The members of any such

treasurer and such other duties as may be specified in these By-Laws or as may
be assigned to him from time to time by the Board of Directors, or the
President.

          Section 4.10. ADDITIONAL OFFICERS. The Board of Directors may appoint
such other officers and agents as it may deem appropriate, and such other
officers and agents shall hold their offices for such terms and shall exercise
such powers and perform such duties as may be determined from time to time by
the Board of Directors. The Board of Directors from time to time may delegate to
any officer or agent the power to appoint subordinate officers or agents and to
prescribe their respective rights, terms of office, authorities and duties. Any
such officer or agent may remove any such subordinate officer or agent appointed
by him, for or without cause.

          Section 4.11. SECURITY. The Board of Directors may require any
officer, agent or employee of the Corporation to provide security for the
faithful performance of his duties, in such amount and of such character as may
be determined from time to time by the Board of Directors.

                                    ARTICLE V

                                  CAPITAL STOCK

          Section 5.01. CERTIFICATES OF STOCK, UNCERTIFICATED SHARES. The shares
of the Corporation shall be represented by certificates, provided that the Board
of Directors may provide by resolution or resolutions that some or all of any or
all classes or series of the stock of the Corporation shall be uncertificated
shares. Any such resolution shall not apply to shares represented by a
certificate until each certificate is surrendered to the Corporation.
Notwithstanding the adoption of such a resolution by the Board of Directors,
every holder of stock in the Corporation represented by certificates and upon
request every holder of uncertificated shares shall be entitled to have a
certificate signed by, or in the name of the Corporation, by the President or a
Vice President, and by the Treasurer or an Assistant Treasurer, or the Secretary
or an Assistant Secretary, representing the number of shares registered in
certificate form. Such certificate shall be in such form as the Board of
Directors may determine, to the extent consistent with applicable law, the
Certificate of Incorporation and these By-Laws.

          Section 5.02. SIGNATURES; FACSIMILE. All of such signatures on the
certificate may be a facsimile, engraved or printed, to the extent permitted by
law. In case any officer, transfer agent or registrar who has signed, or whose
facsimile signature has been placed upon a certificate shall have ceased to be
such officer, transfer agent or registrar before such certificate is issued, it
may be issued by the Corporation with the same effect as if he were such
officer, transfer agent or registrar at the date of issue.

          Section 5.03. LOST, STOLEN OR DESTROYED CERTIFICATES. The Board of
Directors may direct that a new certificate be issued in place of any
certificate theretofore issued by the 

                                       14
<PAGE>

Corporation alleged to have been lost, stolen or destroyed, upon delivery to the
Board of Directors of an affidavit of the owner or owners of such certificate,
setting forth such allegation. The Board of Directors may require the owner of
such lost, stolen or destroyed certificate, or his legal representative, to give
the Corporation a bond sufficient to indemnify it against any claim that may be
made against it on account of the alleged loss, theft or destruction of any such
certificate or the issuance of any such new certificate.

          Section 5.04. TRANSFER OF STOCK. Upon surrender to the Corporation or
the transfer agent of the Corporation of a certificate for shares, duly endorsed
or accompanied by appropriate evidence of succession, assignment or authority to
transfer, the Corporation shall issue a new certificate to the person entitled
thereto, cancel the old certificate and record the transaction upon its books.
Within a reasonable time after the transfer of uncertificated stock, the
Corporation shall send to the registered owner thereof a written notice
containing the information required to be set forth or stated on certificates
pursuant to Sections 151, 156, 202(a) or 218(a) of the General Corporation Law
of the State of California. Subject to the provisions of the Certificate of
Incorporation and these By-Laws, the Board of Directors may prescribe such
additional rules and regulations as it may deem appropriate relating to the
issue, transfer and registration of shares of the Corporation.

          Section 5.05. RECORD DATE. In order to determine the shareholders
entitled to notice of or to vote at any meeting of shareholders or any
adjournment thereof or entitled to give consent to corporate action without a
meeting, the Board of Directors may fix, in advance, a record date, which record
date shall not precede the date on which the resolution fixing the record date
is adopted by the Board of Directors, and which shall not be more than sixty nor
less than ten days before the date of such meeting nor more than sixty days
prior to such action without a meeting. A determination of shareholders of
record entitled to notice of or to vote at a meeting of shareholders shall apply
to any adjournment of the meeting, provided, however, that the Board of
Directors may fix a new record date for the adjourned meeting. If no record date
has been fixed by the Board of Directors, the record date for determining
shareholders entitled to notice of or to vote at a meeting of shareholders shall
be at the close of business on the business day next preceding the day on which
notice if given or, if notice is waived, at the close of business on the
business day next preceding the day on which the meeting is held.


In order that the Corporation may determine the shareholders entitled to consent
to corporate action in writing without a meeting, the Board of Directors may fix
a record date, which record date shall not precede the date upon which the
resolution fixing the record date is adopted by the Board of Directors, and
which date shall not be more than ten days after the date upon which the
resolution fixing the record date is adopted by the Board of Directors. If no
record date has been fixed by the Board of Directors, the record date for
determining shareholders entitled to consent to corporate action in writing
without a meeting, (i) when no prior action by the Board has been taken, shall
be the day on which the first written consent is given, or (ii) when prior
action of the 

                                       15
<PAGE>

Board has been taken, shall be at the close of business on the day on which the
Board adopts the resolution relating thereto, or the sixtieth (60th) day prior
to the date of such other action, whichever is later.

          In order that the Corporation may determine the shareholders entitled
to receive payment of any dividend or other distribution or allotment of any
rights of the shareholders entitled to exercise any rights in respect of any
change, conversion or exchange of stock, or for the purpose of any other lawful
action (other than action by shareholders by written consent without a meeting),
the Board of Directors may fix a record date, which record date shall not
precede the date upon which the resolution fixing the record date is adopted,
and which record date shall be not more than sixty days prior to such action. If
no record date is fixed, the record date for determining shareholders for any
such purpose shall be at the close of business on the day on which the Board of
Directors adopts the resolution relating thereto, (i) when no prior action by
the Board has been taken, shall be the day on which the first written consent is
given, or (ii) when prior action of the Board has been taken, shall be at the
close of business on the day on which the Board adopts the resolution relating
thereto, or the sixtieth (60th) day prior to the date of such other action,
whichever is later.

          Section 5.06. REGISTERED SHAREHOLDERS. Prior to due surrender of a
certificate for registration of transfer, the Corporation may treat the
registered owner as the person exclusively entitled to receive dividends and
other distributions, to vote, to receive notice and otherwise to exercise all
the rights and powers of the owner of the shares represented by such
certificate, and the Corporation shall not be bound to recognize any equitable
or legal claim to or interest in such shares on the part of any other person,
whether or not the Corporation shall have notice of such claim or interests.
Whenever any transfer of shares shall be made for collateral security, and not
absolutely, it shall be so expressed in the entry of the transfer if, when the
certificates are presented to the Corporation for transfer or uncertificated
shares are requested to be transferred, both the transferor and transferee
request the Corporation to do so.

          Section 5.07. TRANSFER AGENT AND REGISTRAR. The Board of Directors may
appoint one or more transfer agents and one or more registrars, and may require
all certificates representing shares to bear the signature of any such transfer
agents or registrars.

                                   ARTICLE VI

                                 INDEMNIFICATION

          Section 6.01. NATURE OF INDEMNITY. The Corporation shall indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative, by reason of the fact that he is or
was or has agreed to become a director or officer of the Corporation, or is or
was serving or has agreed to serve at the request of the Corporation as a
director or officer, of another corporation, partnership, joint venture, trust
or other enterprise, or by reason of any 

                                       16
<PAGE>

action alleged to have been taken or omitted in such capacity, and may indemnify
any person who was or is a party or is threatened to be made a party to such an
action, suit or proceeding by reason of the fact that he is or was or has agreed
to become an employee or agent of the Corporation, or is or was serving or has
agreed to serve at the request of the Corporation as an employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees) , judgments, fines and amounts paid
in settlement actually and reasonably incurred by him or on his behalf in
connection with such action, suit or proceeding and any appeal therefrom, if he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the Corporation, and, with respect to any
criminal action or proceeding had no reasonable cause to believe his conduct was
unlawful; except that in the case of an action or suit by or in the right of the
Corporation to procure a judgment in its favor (1) such indemnification shall be
limited to expenses (including attorneys' fees) actually and reasonably incurred
by such person in the defense or settlement of such action or suit, and (2) no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the Corporation
unless and only to the extent that the court in which such action or suit was
brought shall determine upon application that, despite the adjudication of
liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which the court
shall deem proper.

          The termination of any action, suit or proceeding by judgment, order
settlement, conviction, or upon a plea of NOLO CONTENDERE or its equivalent,
shall not, of itself, create a presumption that the person did not act in good
faith and in a manner which he reasonably believed to be in or not opposed to
the best interests of the Corporation, and, with respect to any criminal action
or proceeding, had reasonable cause to believe that his conduct was unlawful.

          Section 6.02. SUCCESSFUL DEFENSE. To the extent that a director,
officer, employee or agent of the Corporation has been successful on the merits
or otherwise in defense of any action, suit or proceeding referred to in Section
6.01 hereof or in defense of any claim, issue or matter therein, he shall be
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection therewith.

          Section 6.03. DETERMINATION THAT INDEMNIFICATION IS PROPER. Any
indemnification of a director or officer of the Corporation under Section 6.01
hereof (unless ordered by a court) shall be made by the Corporation unless a
determination is made that indemnification of the director or officer is not
proper in the circumstances because he has not met the applicable standard of
conduct set forth in Section 6.01 hereof. Any indemnification of an employee or
agent of the Corporation under Section 6.01 hereof (unless ordered by a court)
may be made by the Corporation upon a determination that indemnification of the
employee or agent is proper in the circumstances because he has met the
applicable standard of conduct set forth in Section 6.01 hereof. Any such
determination shall be made:

          (1) by the Board of Directors by a majority vote of a quorum
consisting of 

                                       17
<PAGE>

directors who were not parties to such action, suit or proceeding, or

          (2) if such a quorum is not obtainable, or, even if obtainable a
quorum of disinterested directors so directs, by independent legal counsel in a
written opinion, or

          (3) by the shareholders, with the shares owned by the person to be
indemnified not being entitled to vote thereon, or

          (4) by the court in which the proceeding is or was pending upon
application made by the corporation or the agent or the attorney or other person
rendering services in connection with the defense, whether or not the
application by the agent, attorney or other person is opposed by the
corporation.

          Section 6.04. ADVANCE PAYMENT OF EXPENSES. Expenses (including
attorneys' fees) incurred by a director or officer in defending any civil,
criminal, administrative or investigative action, suit or proceeding shall be
paid by the Corporation in advance of the final disposition of such action, suit
or proceeding upon receipt of an undertaking by or on behalf of the director or
officer to repay such amount if it shall ultimately be determined that he is not
entitled to be indemnified by the Corporation as authorized in this Article.
Such expenses (including attorneys' fees) incurred by other employees and agents
may be so paid upon such terms and conditions, if any, as the Board of Directors
deems appropriate. The Board of Directors may authorize the Corporation's
counsel to represent such director, officer, employee or agent in any action,
suit or proceeding, whether or not the Corporation is a party to such action,
suit or proceeding.

          No indemnification or advance shall be made under this section, except
as provided in Section 6.02 or paragraph (4) of Section 6.03, in any
circumstance where it appears: (1) that it would be inconsistent with a
provision of the articles, bylaws, a resolution of the shareholders, or an
agreement in effect at the time of the accrual of the alleged cause of action
asserted in the proceeding in which the expenses were incurred or other amounts
were paid, which prohibits or otherwise limits indemnification or (2) that it
would be inconsistent with any condition expressly imposed by a court in
approving a settlement.

          Section 6.05. PROCEDURE FOR INDEMNIFICATION OF DIRECTORS AND OFFICERS.
Any indemnification of a director or officer of the Corporation under Sections
6.01 and 6.02, or advance of costs, charges and expenses to a director or
officer under Section 6.04 of this Article, shall be made promptly, and in any
event within 30 days, upon the written request of the director or officer. If a
determination by the Corporation that the director or officer is entitled to
indemnification pursuant to this Article is required, and the Corporation fails
to respond within sixty days to a written request for indemnity, the Corporation
shall be deemed to have approved such request. If the Corporation denies a
written request for indemnity or advancement of expenses, in whole or in part,
or if payment in full pursuant to such request is not made within 30 days, the
right to indemnification or advances as granted by this Article shall be
enforceable by 

                                       18
<PAGE>

the director or officer in any court of competent jurisdiction. Such person's
costs and expenses incurred in connection with successfully establishing his
right to indemnification, in whole or in part, in any such action shall also be
indemnified by the Corporation. It shall be a defense to any such action (other
than an action brought to enforce a claim for the advance of costs, charges and
expenses under Section 6.04 of this Article where the required undertaking, if
any, has been received by the Corporation) that the claimant has not met the
standard of conduct set forth in Section 6.01 of this Article, but the burden of
proving such defense shall be on the Corporation. Neither the failure of the
Corporation (including its Board of Directors, its independent legal counsel,
and its shareholders) to have made a determination prior to the commencement of
such action that indemnification of the claimant is proper in the circumstances
because he has met the applicable standard of conduct set forth in Section 6.01
of this Article, nor the fact that there has been an actual determination by the
Corporation (including its Board of Directors, its independent legal counsel,
and its shareholders) that the claimant has not met such applicable standard of
conduct, shall be a defense to the action or create a presumption that the
claimant has not met the applicable standard of conduct.

          Section 6.06. SURVIVAL; PRESERVATION OF OTHER RIGHTS. The foregoing
indemnification provisions shall be deemed to be a contract between the
Corporation and each director, officer, employee and agent who serves in any
such capacity at any time while these provisions as well as the relevant
provisions of the California Corporation Law are in effect and any repeal or
modification thereof shall not affect any right or obligation then existing with
respect to any state of facts then or previously existing or any action, suit or
proceeding previously or thereafter brought or threatened based in whole or in
part upon any such state of facts. Such a "contract right" may not be modified
retroactively without the consent of such director, officer, employee or agent.

          The indemnification provided by this Article VI shall not be deemed
exclusive of any other rights to which those indemnified may be entitled under
any by-law, agreement, vote of shareholders or disinterested directors or
otherwise, both as to action in his official capacity and as to action in
another capacity while holding such office, and shall continue as to a person
who has ceased to be a director, officer, employee or agent and shall inure to
the benefit of the heirs, executors and administrators of such a person.

          Section 6.07. INSURANCE. The Corporation shall purchase and maintain
insurance on behalf of any person who is or was or has agreed to become a
director or officer of the Corporation, or is or was serving at the request of
the Corporation as a director or officer of another corporation, partnership,
joint venture, trust or other enterprise against any liability asserted against
him and incurred by him or on his behalf in any such capacity, or arising out of
his status as such, whether or not the Corporation would have the power to
indemnify him against such liability under the provisions of this Article,
PROVIDED that such insurance is available on acceptable terms, which
determination shall be made by a vote of a majority of the entire Board of
Directors.

                                       19
<PAGE>

          Section 6.08. SEVERABILITY. If this Article or any portion hereof
shall be invalidated on any ground by any court of competent jurisdiction, then
the Corporation shall nevertheless indemnify each director or officer and may
indemnify each employee or agent of the Corporation as to costs, charges and
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement with respect to any action, suit or proceeding, whether civil,
criminal, administrative or investigative, including an action by or in the
right of the Corporation, to the fullest extent permitted by any applicable
portion of this Article that shall not have been invalidated and to the fullest
extent permitted by applicable law.

                                   ARTICLE VII

                                     OFFICES

          Section 7.01. PRINCIPAL OFFICES. The Board of Directors shall fix the
location of the principal executive office of the corporation at any place
within or outside the State of California. If the principal executive office is
located outside this state, and the corporation has one or more business offices
in this state, the Board of Directors shall likewise fix and designate a
principal business office in the State of California.

          Section 7.02. OTHER OFFICES. The Corporation may maintain offices or
places of business at such other locations within or without the State of
California as the Board of Directors may from time to time determine or as the
business of the Corporation may require.

                                  ARTICLE VIII

                               GENERAL PROVISIONS

          Section 8.01. DIVIDENDS. Subject to any applicable provisions of law
and the Certificate of Incorporation, dividends upon the shares of the
Corporation may be declared by the Board of Directors at any regular or special
meeting of the Board of Directors and any such dividend may be paid in cash,
property, or shares of the Corporation's Capital Stock.

          A member of the Board of Directors, or a member of any Committee
designated by the Board of Directors shall be fully protected in relying in good
faith upon the records of the Corporation and upon such information, opinions,
reports or statements presented to the Corporation by any of its officers or
employees, or Committees of the Board of Directors, or by any other person as to
matters the Director reasonably believes are within such other person's
professional or expert competence and who has been selected with reasonable care
by or on behalf of the Corporation, as to the value and amount of the assets,
liabilities and/or net profits of the Corporation, or any other facts pertinent
to the existence and amount of surplus or other funds from which dividends might
properly be declared and paid.

                                       20
<PAGE>

          Section 8.02. RESERVES. There may be set aside out of any funds of the
Corporation available for dividends such sum or sums as the Board of Directors
from time to time, in its absolute discretion thinks proper as a reserve or
reserves to meet contingencies, or for equalizing dividends, or for repairing or
maintaining any property of the Corporation or for such other purpose as the
Board of Directors shall think conducive to the interest of the Corporation, and
the Board of Directors may similarly modify or abolish any such reserve.

          Section 8.03. EXECUTION OF INSTRUMENTS. The President, any Vice
President, the Secretary or the Treasurer may enter into any contract or execute
and deliver any instrument in the name and on behalf of the Corporation. The
Board of Directors or the President may authorize any other officer or agent to
enter into any contract or execute and deliver any instrument in the name and on
behalf of the Corporation. Any such authorization may be general or limited to
specific contracts or instruments.

          Section 8.04. CORPORATE INDEBTEDNESS. No loan shall be contracted on
behalf of the Corporation, and no evidence of indebtedness shall be issued in
its name, unless authorized by the Board of Directors or the President. Such
authorization may be general or confined to specific instances. Loans so
authorized may be effected at any time for the Corporation from any bank, trust
company or other institution, or from any firm, corporation or individual. All
bonds, debentures, notes and other obligations or evidences of indebtedness of
the Corporation issued for such loans shall be made, executed and delivered as
the Board of Directors or the President shall authorize. When so authorized by
the Board of Directors or the President, any part of or all the properties,
including contract rights, assets, business or good will of the Corporation,
whether then owned or thereafter acquired, may be mortgaged, pledged,
hypothecated or conveyed or assigned in trust as security for the payment of
such bonds, debentures, notes and other obligations or evidences of indebtedness
of the Corporation, and of the interest thereon, by instruments executed and
delivered in the name of the Corporation.

          Section 8.05. DEPOSITS. Any funds of the Corporation may be deposited

authorized by the Board of Directors or by the President, any Vice President,
the Secretary or the Treasurer or any other officers designated by the Board of
Directors or the President may sell, transfer, endorse, and assign any shares of
stock, bonds or other securities owned by or held in the name of the
Corporation, and may make, execute and deliver in the name of the Corporation,
under its

any meeting of shareholders of any corporation in which the Corporation may 
hold stock, and to act, vote (or execute proxies to vote) and exercise in 
person or by proxy all other rights, powers and privileges incident to the 
ownership of such stock. Such officers acting on behalf of the Corporation 
shall have full power and authority to execute any instrument expressing 
consent to or dissent from any action of any such corporation without a 
meeting. The Board of Directors may by resolution from time to time confer 
such power and authority upon any other person or persons.

          Section 8.09. FISCAL YEAR. The fiscal year of the Corporation shall

          Section 8.11. BOOKS AND RECORDS: INSPECTION. Except to the extent 
otherwise required by law, the books and records of the Corporation shall be 
kept at such place or places within or without the State of California as may

                                    ARTICLE I

                                  SHAREHOLDERS

     Section 1.01. ANNUAL MEETINGS. The annual meeting of the shareholders of
the Corporation for the election of directors and for the transaction of such
other business as properly may come before such meeting shall be held at such
place, either within or without the State of California, and at such date and
hour, as may be fixed from time to time by resolution of the Board of Directors
and set forth in the notice or waiver of notice of the meeting.

     Section 1.02. SPECIAL MEETINGS. Special meetings of the shareholders may be
called at any time by the President (or, in the event of his absence or
disability, by any Vice President), or by the Board of Directors. A special
meeting shall be called by the President (or, in the event of his absence or
disability, by any Vice President), or by the Secretary, immediately upon
receipt of a written request therefor by shareholders holding in the aggregate
not less than 10% of the outstanding shares of the Corporation at the time
entitled to vote at any meeting of the shareholders. If such officers or the
Board of Directors shall fail to call such meeting within 20 days after receipt
of such request, any shareholder executing such request may call such meeting to
be held at a time requested by the person or persons calling the meeting, not
less than 35 nor more than 60 days after the receipt of the request. Such
special meetings of the shareholders shall be held at such places, within or
without the State of California, as shall be specified in the respective notices
or waivers of notice thereof.

     Section 1.03. NOTICE OF MEETINGS; WAIVER. The Secretary or any Assistant
Secretary shall cause written notice of the place, date and hour of each meeting
of the shareholders, and, (i) in the case of a special meeting, the general
nature of the business to be transacted, or (ii) in the case of the annual
meeting those matters which the Board of Directors, at the time of giving the
notice, intends to present for action by the shareholders, to be given
personally or by first-class mail, not less than ten nor more than sixty days
prior to the meeting, to each shareholder of record entitled to vote at such
meeting. The notice of any meeting at which directors are to be elected shall
include the name of any nominee or nominees which, at the time of the notice,
management intends to present for election.

     If action is proposed to be taken at any meeting for approval of (i) a
contract or transaction in which a director has a direct or indirect financial
interest, pursuant to Section 310 of the Corporations Code of California, (ii)
an amendment of the articles of incorporation, pursuant to Section 902 of such
Code, (iii) a reorganization of the corporation, pursuant to Section 1201 of
such Code, (iv) a voluntary dissolution of the corporation, pursuant to Section

<PAGE>

1900 of such Code, or (v) a distribution in dissolution other than in accordance
with the rights of outstanding preferred shares pursuant to Section 2007 of such
Code, the notice shall also state the general nature of such proposal.

     If such notice is mailed, it shall be deemed to have been given to a
shareholder when deposited in the United States mail, postage prepaid, directed
to the shareholder at his address as it appears on the record of shareholders of
the Corporation, or, if he shall have filed with the Secretary of the
Corporation a written request that notices to him be mailed to some other
address, then directed to him at such other address. If no such address appears
on the corporation's books or has been so given, notice shall be deemed to have
been given if sent by first-class mail or telegraphic or other written
communication to the corporation's principal executive office, or if published
at least once in a newspaper of general circulation in the county where such
office is located.

     If any notice addressed to a shareholder at the address of such shareholder
appearing on the books of the corporation is returned to the corporation by the
United States Postal Service marked to indicate that the United States Postal
Service is unable to deliver the notice to the shareholder at such address, all
future notices or reports shall be deemed to have been duly given without
further mailing if the same shall be available to the shareholder upon written
demand of the shareholder at the principal executive office of the corporation
for a period of one year from the date of the giving of such notice. Such
further notice shall be given as may be required by law.

     No notice of any meeting of shareholders need be given to any shareholder
who submits a signed waiver of notice, whether before or after the meeting.
Neither the business to be transacted at, nor the purpose of, any regular or
special meeting of the shareholders need be specified in a written waiver of
notice. The attendance of any shareholder at a meeting of shareholders shall
constitute a waiver of notice of such meeting, except when the shareholder
attends a meeting for the express purpose of objecting, at the beginning of the
meeting, to the transaction of any business on the ground that the meeting is
not lawfully called or convened.

     An affidavit of the mailing or other means of giving any notice of any
shareholders' meeting shall be executed by the Secretary, Assistant Secretary or
any transfer agent of the corporation giving such notice, and shall be filed and
maintained in the minute book of the corporation.

     Section 1.04. QUORUM. Except as otherwise required by law or by the
Certificate of Incorporation, the presence in person or by proxy of the holders
of record of a majority of the shares entitled to vote at a meeting of
shareholders shall constitute a quorum for the transaction of business at such
meeting.

     Section 1.05. VOTING. If, pursuant to Section 5.05 of these By-Laws, a
record date has been fixed, every holder of record of shares entitled to vote at
a meeting of shareholders 

                                       2
<PAGE>

shall be entitled to one vote for each share outstanding in his name on the
books of the Corporation at the close of business on such record date. If no
record date has been fixed, then every holder of record of shares entitled to
vote at a meeting of shareholders shall be entitled to one vote for each share
of stock standing in his name on the books of the Corporation at the close of
business on the day next preceding the day on which notice of the meeting is
given, or, if notice is waived, at the close of business on the day next
preceding the day on which the meeting is held.

     Any shareholder entitled to vote on any matter (other than the election of
directors) may vote part of the shares in favor of the proposal and refrain from
voting the remaining shares or vote them against the proposal, but, if the
shareholder fails to specify the number of shares such shareholder is voting
affirmatively, it will be conclusively presumed that the shareholder's approving
vote is with respect to all shares such shareholder is entitled to vote. If a
quorum is present, the affirmative vote of the majority of the shares
represented at the meeting and voting on any matter (other than the election of
directors), provided that the shares voting affirmatively must also constitute
at least a majority of the required quorum, shall be the act of the
shareholders, unless the vote of a greater number or voting by classes is
required by the California General Corporation Law or the articles of
incorporation.

     At a shareholders' meeting involving the election of directors, no
shareholder shall be entitled to cumulate votes (i.e., cast for any candidate a
number of votes greater than the number of the shareholder's shares) unless such
candidate or candidates' names have been placed in nomination prior to
commencement of the voting and a shareholder has given notice prior to
commencement of the voting of the shareholder's intention to cumulate votes. If
any shareholder has given such notice, then every shareholder entitled to vote
may cumulate such shareholder's votes for candidates in nomination and give one
candidate a number of votes equal to the number of directors to be elected
multiplied by the number of votes to which such shareholder's shares are
entitled, or distribute the shareholder's votes on the same principle among any
or all of the candidates, as the shareholder thinks fit. The candidates
receiving the highest number of votes, up to the number of directors to be
elected, shall be elected.

     Section 1.06. VOTING BY BALLOT. No vote of the shareholders need be taken
by ballot unless required by law (except that all elections for directors must
be by ballot upon demand by a shareholder at the meeting and before the voting
begins). Any vote which need not be taken by ballot may be conducted by voice
vote or in any manner approved by the meeting.

     Section 1.07. ADJOURNMENT. If a quorum is not present at any meeting of the
shareholders, the shareholders present in person or by proxy shall have the
power to adjourn any such meeting from time to time until a quorum is present.
Notice of any adjourned meeting of the shareholders of the Corporation need not
be given if the place, date and hour thereof are announced at the meeting at
which the adjournment is taken, provided, however, that if the adjournment is
for more than thirty days, or if after the adjournment a new record date for the
adjourned meeting is fixed pursuant to Section 5.05 of these By-Laws, a notice
of the adjourned 

                                       3
<PAGE>

meeting, conforming to the requirements of Section 1.03 hereof, shall be given
to each shareholder of record entitled to vote at such meeting. At any adjourned
meeting at which a quorum is present, any business may be transacted that might
have been transacted on the original date of the meeting.

     Section 1.08. PROXIES. Any shareholder entitled to vote at any meeting of
the shareholders or to express consent to or dissent from corporate action
without a meeting may authorize another person or persons to vote at any such
meeting and express such consent or dissent for him by proxy. A shareholder may
authorize a valid proxy by executing a written instrument signed by such
shareholder, or by causing his or her signature to be affixed to such writing by
any reasonable means including, but not limited to, by facsimile signature, or
by transmitting or authorizing the transmission of a telegram, cablegram or
other means of electronic transmission to the person designated as the holder of
the proxy, a proxy solicitation firm or a like authorized agent. A proxy must be
filed with the Secretary of the corporation. No such proxy shall be voted or
acted upon after the expiration of eleven months from the date of such proxy,
unless such proxy provides for a longer period. Every proxy shall be revocable
at the pleasure of the shareholder executing it, except in those cases where
applicable law provides that a proxy shall be irrevocable. A shareholder may
revoke any proxy which is not irrevocable by attending the meeting and voting in
person or by filing an instrument in writing revoking the proxy or by filing
another duly executed proxy bearing a later date with the Secretary. Proxies by
telegram, cablegram or other electronic transmission must either set forth or be
submitted with information from which it can be determined that the telegram,
cablegram or other electronic transmission was authorized by the shareholder.
Any copy, facsimile telecommunication or other reliable reproduction of a
writing or transmission created pursuant to this section may be substituted or
used in lieu of the original writing or transmission for any and all purposes
for which the original writing or transmission could be used, provided that such
copy, facsimile telecommunication or other reproduction shall be a complete
reproduction of the entire original writing or transmission.

     Section 1.09. ORGANIZATION; PROCEDURE. At every meeting of shareholders the
presiding officer shall be the President or, in the event of his absence or
disability, a presiding officer chosen by a majority of the shareholders present
in person or by proxy. The Secretary, or in the event of his absence or
disability, the Assistant Secretary, if any, or if there be no Assistant
Secretary, in the absence of the Secretary, an appointee of the presiding
officer, shall act as Secretary of the meeting. The order of business and all
other matters of procedure at every meeting of shareholders may be determined by
such presiding officer.

     Section 1.10. CONSENT OF SHAREHOLDERS IN LIEU OF MEETING. To the fullest
extent permitted by law, whenever the vote of shareholders at a meeting thereof
is required or permitted to be taken for or in connection with any corporate
action, such action may be taken without a meeting, without prior notice and
without a vote of shareholders, if a consent or consents in writing, setting
forth the action so taken, shall be signed by the holders of outstanding stock
having not less than the minimum number of votes that would be necessary to
authorize or take 

                                       4
<PAGE>

such action at a meeting at which all shares entitled to vote thereon were
present and voted and shall be filed with the Secretary of the corporation and
shall be maintained in the corporate records. In the case of election of
directors, such consent shall be effective only if signed by the holders of all
outstanding shares entitled to vote for the election of directors; provided,
however, that a director may be elected at any time to fill a vacancy not
created by removal and not filled by the directors by the written consent of the
holders of a majority of the outstanding shares entitled to vote for the
election of directors.

     Every written consent shall bear the date of signature of each shareholder
or member who signs the consent and no written consent shall be effective to
take the corporate action referred to therein unless, within sixty days of the
earliest dated consent delivered in the manner required by law to the
Corporation, written consents signed by a sufficient number of holders or
members to take action are delivered to the Corporation. Any shareholder giving
a written consent, or the shareholder's proxy holders, or a transferee of the
shares or a personal representative of the shareholder or their respective proxy
holder, may revoke the consent by a writing received by the Secretary of the
corporation prior to the time that written consents of the number of shares
required to authorize the proposed action have been filed with the Secretary.

                               BOARD OF DIRECTORS

     Section 2.01. GENERAL POWERS. Except as may otherwise be provided by law,
by the Certificate of Incorporation or by these By-Laws, the property, affairs
and business of the Corporation shall be managed by or under the direction of
the Board of Directors and the Board of Directors may exercise all the powers of
the Corporation.

     Section 2.02. NUMBER AND TERM OF OFFICE. The number of Directors
constituting the entire Board of Directors shall be not less than one nor more
than thirteen, which number may be modified from time to time by resolution of
the Board of Directors, but in no event shall the number of Directors be less
than one. Each Director (whenever elected) shall hold office until his successor
has been duly elected and qualified, or until his earlier death, resignation or
removal.

     Section 2.03. ELECTION OF DIRECTORS. Except as otherwise provided in
Sections 2.12 and 2.13 of these By-Laws, the Directors shall be elected at each
annual meeting of the shareholders. If the annual meeting for the election of
Directors is not held on the date designated therefor, the Directors shall cause
the meeting to be held as soon thereafter as convenient. At each meeting of the
shareholders for the election of Directors, provided a quorum is present, the
Directors shall be elected by a plurality of the votes validly cast in such
election.

                                       5
<PAGE>

     Section 2.04. ANNUAL AND REGULAR MEETINGS. The annual meeting of the Board
of Directors for the purpose of electing officers and for the transaction of
such other business as may come before the meeting shall be held as soon as
possible following adjournment of the annual meeting of the shareholders at the
place of such annual meeting of the shareholders. Notice of such annual meeting
of the Board of Directors need not be given. The Board of Directors from time to
time may by resolution provide for the holding of regular meetings and fix the
place (which may be within or without the State of California) and the date and
hour of such meetings. Notice of regular meetings need not be given, provided,
however, that if the Board of Directors shall fix or change the time or place of
any regular meeting, notice of such action shall be mailed promptly, or sent by
telegram, radio or cable, to each Director who shall not have been present at
the meeting at which such action was taken, addressed to him at his usual place
of business, or shall be delivered to him personally. Notice of such action need
not be given to any Director who attends the first regular meeting after such
action is taken without protesting the lack of notice to him, prior to or at the
commencement of such meeting, or to any Director who submits a signed waiver of
notice, whether before or after such meeting.

     Section 2.05. SPECIAL MEETINGS; NOTICE. Special meetings of the Board of
Directors shall be held whenever called by the President or, in the event of his
absence or disability, by any Vice President, at such place (within or without
the State of California), date and hour as may be specified in the respective
notices or waivers of notice of such meetings. The notice need not specify the
purpose of the meeting nor the place if the meeting is to be held at the
principal executive office of the corporation.

     Special meetings of the Board of Directors may be called on 24 hours'
notice, if notice is given to each Director personally or by telephone or
telegram, or on five days' notice, if notice is mailed to each Director,
addressed to him at his usual place of business. Notice of any special meeting
need not be given to any Director who attends such meeting without protesting
the lack of notice to him, prior to or at the commencement of such meeting, or
to any Director who submits a signed waiver of notice, whether before or after
such meeting, and any business may be transacted thereat.

     Section 2.06. QUORUM; VOTING. At all meetings of the Board of Directors,
the presence of a majority of the total authorized number of Directors shall
constitute a quorum for the transaction of business. Except as otherwise
required by law, the vote of a majority of the Directors present at any meeting
at which a quorum is present shall be the act of the Board of Directors, subject
to the provisions of Section 310 of the Corporations Code of California
(approval of contracts or transactions in which a director has a direct or
indirect material financial interest), Section 311 (appointment of committees),
and Section 317 (e) (indemnification of directors). A meeting at which a quorum
is initially present may continue to transact business notwithstanding the
withdrawal of directors, if any action taken is approved by at least a majority
of the required quorum for such meeting.

                                       6
<PAGE>

     Section 2.07. ADJOURNMENT. A majority of the Directors present, whether or
not a quorum is present, may adjourn any meeting of the Board of Directors to
another time or place. No notice need be given of any adjourned meeting unless
the meeting is adjourned for more than twenty-four (24) hours or unless the time
and place of the adjourned meeting are not announced at the time of adjournment,
in which case notice conforming to the requirements of Section 2.05 shall be
given to each Director.

     Section 2.08. ACTION WITHOUT A MEETING. Any action required or permitted to
be taken by the Board of Directors may be taken without a meeting, if all
members of the Board shall individually or collectively consent in writing to
such action. Such action by written consent shall have the same force and effect
as a unanimous vote of the Board of Directors. Such written consent or consents
shall be filed with the minutes of the proceedings of the Board.

     Section 2.09. REGULATIONS: MANNER OF ACTING. To the extent consistent with
applicable law, the Certificate of Incorporation and these By-Laws, the Board of
Directors may adopt such rules and regulations for the conduct of meetings of
the Board of Directors and for the management of the property, affairs and
business of the Corporation as the Board of Directors may deem appropriate. The
Directors shall act only as a Board, and the individual Directors shall have no
power as such.

     Section 2.10. ACTION BY TELEPHONIC COMMUNICATIONS. Members of the Board of
Directors may participate in a meeting of the Board of Directors by means of
conference telephone or similar communications equipment by means of which all
persons participating in the meeting can hear each other, and participation in a
meeting pursuant to this provision shall constitute presence in person at such
meeting.

     Section 2.11. RESIGNATIONS. Any Director may resign at any time by
delivering a written notice of resignation, signed by such Director, to the
President or the Secretary. Unless otherwise specified therein, such resignation
shall take effect upon delivery.

     Section 2.12. REMOVAL OF DIRECTORS. Any Director may be removed at any
time, either for or without cause, upon the affirmative vote of the holders of a
majority of the outstanding shares of stock of the Corporation entitled to vote
for the election of such Director, cast at a special meeting of shareholders
called for the purpose, or by court order. Any vacancy in the Board of Directors
caused by any such removal may be filled at such meeting by the shareholders
entitled to vote for the election of the Director so removed. If such

death, resignation or removal. Any such vacancy or newly created directorship
may also be filled at any time by vote of the shareholders.

presented to the Corporation by any of the Corporation's officers or employees,
or Committees designated by the Board of Directors, or by any other person as to
the matters the member reasonably believes are within such other person's
professional or expert competence and who has been selected with reasonable care
by or on behalf of the Corporation.

the committee, special meetings of committees may also be called by resolution
of the Board of Directors and notice of special meetings of committees shall
also be given to all alternate members, who shall have the right to attend all
meetings of the committee. Each such Committee may fix its own rules of

present at any meeting and not disqualified from voting, whether or not he or

member.

                                  CAPITAL STOCK

     Section 5.01. CERTIFICATES OF STOCK, UNCERTIFICATED SHARES. The shares of
the Corporation shall be represented by certificates, provided that the Board of
Directors may provide by resolution or resolutions that some or all of any or
all classes or series of the stock of the Corporation shall be uncertificated
shares. Any such resolution shall not apply to shares represented by a
certificate until each certificate is surrendered to the Corporation.
Notwithstanding the adoption of such a resolution by the Board of Directors,
every holder of stock in the Corporation represented by certificates and upon
request every holder of uncertificated shares shall be entitled to have a
certificate signed by, or in the name of the Corporation, by the President or a
Vice President, and by the Treasurer or an Assistant Treasurer, or the Secretary
or an Assistant Secretary, representing the number of shares registered in
certificate form. Such certificate shall be in such form as the Board of
Directors may determine, to the extent consistent with applicable law, the
Certificate of Incorporation and these By-Laws.

     Section 5.02. SIGNATURES; FACSIMILE. All of such signatures on the
certificate may be a facsimile, engraved or printed, to the extent permitted by
law. In case any officer, transfer agent or registrar who has signed, or whose
facsimile signature has been placed upon a certificate shall have ceased to be
such officer, transfer agent or registrar before such certificate is issued, it
may be issued by the Corporation with the same effect as if he were such
officer, transfer agent or registrar at the date of issue.

     Section 5.03. LOST, STOLEN OR DESTROYED CERTIFICATES. The Board of
Directors may direct that a new certificate be issued in place of any
certificate theretofore issued by the 

                                       14
<PAGE>

Corporation alleged to have been lost, stolen or destroyed, upon delivery
to the Board of Directors of an affidavit of the owner or owners of such
certificate, setting forth such allegation. The Board of Directors may require
the owner of such lost, stolen or destroyed certificate, or his legal
representative, to give the Corporation a bond sufficient to indemnify it
against any claim that may be made against it on account of the alleged loss,
theft or destruction of any such certificate or the issuance of any such new
certificate.

     Section 5.04. TRANSFER OF STOCK. Upon surrender to the Corporation or the
transfer agent of the Corporation of a certificate for shares, duly endorsed or
accompanied by appropriate evidence of succession, assignment or authority to
transfer, the Corporation shall issue a new certificate to the person entitled
thereto, cancel the old certificate and record the transaction upon its books.
Within a reasonable time after the transfer of uncertificated stock, the
Corporation shall send to the registered owner thereof a written notice
containing the information required to be set forth or stated on certificates
pursuant to Sections 151, 156, 202(a) or 218(a) of the General Corporation Law
of the State of California. Subject to the provisions of the Certificate of
Incorporation and these By-Laws, the Board of Directors may prescribe such
additional rules and regulations as it may deem appropriate relating to the
issue, transfer and registration of shares of the Corporation.

     Section 5.05. RECORD DATE. In order to determine the shareholders entitled
to notice of or to vote at any meeting of shareholders or any adjournment
thereof or entitled to give consent to corporate action without a meeting, the
Board of Directors may fix, in advance, a record date, which record date shall
not precede the date on which the resolution fixing the record date is adopted
by the Board of Directors, and which shall not be more than sixty nor less than
ten days before the date of such meeting nor more than sixty days prior to such
action without a meeting. A determination of shareholders of record entitled to
notice of or to vote at a meeting of shareholders shall apply to any adjournment
of the meeting, provided, however, that the Board of Directors may fix a new
record date for the adjourned meeting. If no record date has been fixed by the
Board of Directors, the record date for determining shareholders entitled to
notice of or to vote at a meeting of shareholders shall be at the close of
business on the business day next preceding the day on which notice if given or,
if notice is waived, at the close of business on the business day next preceding
the day on which the meeting is held.


In order that the Corporation may determine the shareholders entitled to consent
to corporate action in writing without a meeting, the Board of Directors may fix
a record date, which record date shall not precede the date upon which the
resolution fixing the record date is adopted by the Board of Directors, and
which date shall not be more than ten days after the date upon which the
resolution fixing the record date is adopted by the Board of Directors. If no
record date has been fixed by the Board of Directors, the record date for
determining shareholders entitled to consent to corporate action in writing
without a meeting, (i) when no prior action by the Board has been taken, shall
be the day on which the first written consent is given, or (ii) when prior
action of the 

                                       15
<PAGE>

Board has been taken, shall be at the close of business on the day
on which the Board adopts the resolution relating thereto, or the sixtieth
(60th) day prior to the date of such other action, whichever is later.

     In order that the Corporation may determine the shareholders entitled to
receive payment of any dividend or other distribution or allotment of any rights
of the shareholders entitled to exercise any rights in respect of any change,
conversion or exchange of stock, or for the purpose of any other lawful action
(other than action by shareholders by written consent without a meeting), the
Board of Directors may fix a record date, which record date shall not precede
the date upon which the resolution fixing the record date is adopted, and which
record date shall be not more than sixty days prior to such action. If no record
date is fixed, the record date for determining shareholders for any such purpose
shall be at the close of business on the day on which the Board of Directors
adopts the resolution relating thereto, (i) when no prior action by the Board
has been taken, shall be the day on which the first written consent is given, or
(ii) when prior action of the Board has been taken, shall be at the close of
business on the day on which the Board adopts the resolution relating thereto,
or the sixtieth (60th) day prior to the date of such other action, whichever is
later.

     Section 5.06. REGISTERED SHAREHOLDERS. Prior to due surrender of a
certificate for registration of transfer, the Corporation may treat the
registered owner as the person exclusively entitled to receive dividends and
other distributions, to vote, to receive notice and otherwise to exercise all
the rights and powers of the owner of the shares represented by such
certificate, and the Corporation shall not be bound to recognize any equitable
or legal claim to or interest in such shares on the part of any other person,
whether or not the Corporation shall have notice of such claim or interests.
Whenever any transfer of shares shall be made for collateral security, and not
absolutely, it shall be so expressed in the entry of the transfer if, when the
certificates are presented to the Corporation for transfer or uncertificated
shares are requested to be transferred, both the transferor and transferee
request the Corporation to do so.

     Section 5.07. TRANSFER AGENT AND REGISTRAR. The Board of Directors may
appoint one or more transfer agents and one or more registrars, and may require
all certificates representing shares to bear the signature of any such transfer
agents or registrars.

                                   ARTICLE VI

                                 INDEMNIFICATION

     Section 6.01. NATURE OF INDEMNITY. The Corporation shall indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative, by reason of the fact that he is or
was or has agreed to become a director or officer of the Corporation, or is or
was serving or has agreed to serve at the request of the Corporation as a
director or officer, of another corporation, partnership, joint venture, trust
or other enterprise, or by reason of any 

                                       16
<PAGE>

action alleged to have been taken or omitted in such capacity, and may indemnify
any person who was or is a party or is threatened to be made a party to such an
action, suit or proceeding by reason of the fact that he is or was or has agreed
to become an employee or agent of the Corporation, or is or was serving or has
agreed to serve at the request of the Corporation as an employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees) , judgments, fines and amounts paid
in settlement actually and reasonably incurred by him or on his behalf in
connection with such action, suit or proceeding and any appeal therefrom, if he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the Corporation, and, with respect to any
criminal action or proceeding had no reasonable cause to believe his conduct was
unlawful; except that in the case of an action or suit by or in the right of the
Corporation to procure a judgment in its favor (1) such indemnification shall be
limited to expenses (including attorneys' fees) actually and reasonably incurred
by such person in the defense or settlement of such action or suit, and (2) no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the Corporation
unless and only to the extent that the court in which such action or suit was
brought shall determine upon application that, despite the adjudication of
liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which the court
shall deem proper.

     The termination of any action, suit or proceeding by judgment, order
settlement, conviction, or upon a plea of NOLO CONTENDERE or its equivalent,
shall not, of itself, create a presumption that the person did not act in good
faith and in a manner which he reasonably believed to be in or not opposed to
the best interests of the Corporation, and, with respect to any criminal action
or proceeding, had reasonable cause to believe that his conduct was unlawful.

     Section 6.02. SUCCESSFUL DEFENSE. To the extent that a director, officer,
employee or agent of the Corporation has been successful on the merits or
otherwise in defense of any action, suit or proceeding referred to in Section
6.01 hereof or in defense of any claim, issue or matter therein, he shall be
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection therewith.

     Section 6.03. DETERMINATION THAT INDEMNIFICATION IS PROPER. Any
indemnification of a director or officer of the Corporation under Section 6.01
hereof (unless ordered by a court) shall be made by the Corporation unless a
determination is made that indemnification of the director or officer is not
proper in the circumstances because he has not met the applicable standard of
conduct set forth in Section 6.01 hereof. Any indemnification of an employee or
agent of the Corporation under Section 6.01 hereof (unless ordered by a court)
may be made by the Corporation upon a determination that indemnification of the
employee or agent is proper in the circumstances because he has met the
applicable standard of conduct set forth in Section 6.01 hereof. Any such
determination shall be made:

     (1) by the Board of Directors by a majority vote of a quorum consisting of

                                       17
<PAGE>

directors who were not parties to such action, suit or proceeding, or

     (2) if such a quorum is not obtainable, or, even if obtainable a quorum of
disinterested directors so directs, by independent legal counsel in a written
opinion, or

     (3) by the shareholders, with the shares owned by the person to be
indemnified not being entitled to vote thereon, or

     (4) by the court in which the proceeding is or was pending upon application
made by the corporation or the agent or the attorney or other person rendering
services in connection with the defense, whether or not the application by the
agent, attorney or other person is opposed by the corporation.

     Section 6.04. ADVANCE PAYMENT OF EXPENSES. Expenses (including attorneys'
fees) incurred by a director or officer in defending any civil, criminal,
administrative or investigative action, suit or proceeding shall be paid by the
Corporation in advance of the final disposition of such action, suit or
proceeding upon receipt of an undertaking by or on behalf of the director or
officer to repay such amount if it shall ultimately be determined that he is not
entitled to be indemnified by the Corporation as authorized in this Article.
Such expenses (including attorneys' fees) incurred by other employees and agents
may be so paid upon such terms and conditions, if any, as the Board of Directors
deems appropriate. The Board of Directors may authorize the Corporation's
counsel to represent such director, officer, employee or agent in any action,
suit or proceeding, whether or not the Corporation is a party to such action,
suit or proceeding.

     No indemnification or advance shall be made under this section, except as
provided in Section 6.02 or paragraph (4) of Section 6.03, in any circumstance
where it appears: (1) that it would be inconsistent with a provision of the
articles, bylaws, a resolution of the shareholders, or an agreement in effect at
the time of the accrual of the alleged cause of action asserted in the
proceeding in which the expenses were incurred or other amounts were paid, which
prohibits or otherwise limits indemnification or (2) that it would be
inconsistent with any condition expressly imposed by a court in approving a
settlement.

     Section 6.05. PROCEDURE FOR INDEMNIFICATION OF DIRECTORS AND OFFICERS. Any
indemnification of a director or officer of the Corporation under Sections 6.01
and 6.02, or advance of costs, charges and expenses to a director or officer
under Section 6.04 of this Article, shall be made promptly, and in any event
within 30 days, upon the written request of the director or officer. If a
determination by the Corporation that the director or officer is entitled to
indemnification pursuant to this Article is required, and the Corporation fails
to respond within sixty days to a written request for indemnity, the Corporation
shall be deemed to have approved such request. If the Corporation denies a
written request for indemnity or advancement of expenses, in whole or in part,
or if payment in full pursuant to such request is not made within 30 days, the
right to indemnification or advances as granted by this Article shall be
enforceable by 

                                       18
<PAGE>

the director or officer in any court of competent jurisdiction. Such person's
costs and expenses incurred in connection with successfully establishing his
right to indemnification, in whole or in part, in any such action shall also be
indemnified by the Corporation. It shall be a defense to any such action (other
than an action brought to enforce a claim for the advance of costs, charges and
expenses under Section 6.04 of this Article where the required undertaking, if
any, has been received by the Corporation) that the claimant has not met the
standard of conduct set forth in Section 6.01 of this Article, but the burden of
proving such defense shall be on the Corporation. Neither the failure of the
Corporation (including its Board of Directors, its independent legal counsel,
and its shareholders) to have made a determination prior to the commencement of
such action that indemnification of the claimant is proper in the circumstances
because he has met the applicable standard of conduct set forth in Section 6.01
of this Article, nor the fact that there has been an actual determination by the
Corporation (including its Board of Directors, its independent legal counsel,
and its shareholders) that the claimant has not met such applicable standard of
conduct, shall be a defense to the action or create a presumption that the
claimant has not met the applicable standard of conduct.

     Section 6.06. SURVIVAL; PRESERVATION OF OTHER RIGHTS. The foregoing
indemnification provisions shall be deemed to be a contract between the
Corporation and each director, officer, employee and agent who serves in any
such capacity at any time while these provisions as well as the relevant
provisions of the California Corporation Law are in effect and any repeal or
modification thereof shall not affect any right or obligation then existing with
respect to any state of facts then or previously existing or any action, suit or
proceeding previously or thereafter brought or threatened based in whole or in
part upon any such state of facts. Such a "contract right" may not be modified
retroactively without the consent of such director, officer, employee or agent.

     The indemnification provided by this Article VI shall not be deemed
exclusive of any other rights to which those indemnified may be entitled under
any by-law, agreement, vote of shareholders or disinterested directors or
otherwise, both as to action in his official capacity and as to action in
another capacity while holding such office, and shall continue as to a person
who has ceased to be a director, officer, employee or agent and shall inure to
the benefit of the heirs, executors and administrators of such a person.

     Section 6.07. INSURANCE. The Corporation shall purchase and maintain
insurance on behalf of any person who is or was or has agreed to become a
director or officer of the Corporation, or is or was serving at the request of
the Corporation as a director or officer of another corporation, partnership,
joint venture, trust or other enterprise against any liability asserted against
him and incurred by him or on his behalf in any such capacity, or arising out of
his status as such, whether or not the Corporation would have the power to
indemnify him against such liability under the provisions of this Article,
PROVIDED that such insurance is available on acceptable terms, which
determination shall be made by a vote of a majority of the entire Board of
Directors.

                                       19

     Section 6.08. SEVERABILITY. If this Article or any portion hereof shall be
invalidated on any ground by any court of competent jurisdiction, then the
Corporation shall nevertheless indemnify each director or officer and may
indemnify each employee or agent of the Corporation as to costs, charges and
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement with respect to any action, suit or proceeding, whether civil,
criminal, administrative or investigative, including an action by or in the
right of the Corporation, to the fullest extent permitted by any applicable
portion of this Article that shall not have been invalidated and to the fullest
extent permitted by applicable law.

<PAGE>

               Trustee and to the Trustee and its successors and assigns,

               thereunder, that:

               (i)    the principal of and interest on the Notes will be
                      promptly paid in full when due, whether at maturity, by

                      Holders or the Trustee hereunder or thereunder will be
                      promptly paid in full or performed, all in accordance with
                      the terms hereof and thereof; and

               (ii)   in case of any extension of time of payment or renewal of
                      any Notes or any of such other obligations, that same will
                      be promptly paid in full when due or performed in

                      Failing payment when due of any amount so guaranteed or
                      any performance so guaranteed for whatever reason, the
                      Guarantors shall be jointly and severally obligated to pay
                      the same immediately.

          (b)  The obligations hereunder shall be unconditional, irrespective of
               the validity, regularity or enforceability of the Notes or the
               Indenture, the absence of any action to enforce the same, any
               waiver or consent by any Holder of the Notes with respect to any
               provisions hereof or thereof, the recovery of any judgment
               against the Company, any action to enforce the same or any other
               circumstance which might otherwise constitute a legal or
               equitable discharge or defense of a Guarantor.


          (c)  The following is hereby waived: diligence, presentment, demand of
               payment, filing of claims with a court in the event of insolvency
               or bankruptcy of the Company, any right to require a proceeding
               first against the Company, protest, notice and all demands
               whatsoever.


          (d)  This Guarantee shall not be discharged except by complete
               performance of the obligations contained in the Notes and the
               Indenture or pursuant to Section 6 hereof.


          (e)  If any Holder or the Trustee is required by any court or
               otherwise to return to the Company, the Guarantors, or any
               custodian, Trustee, liquidator or other similar official acting
               in relation to either the Company or the Guarantors, any amount
               paid by either to the Trustee or such Holder, this Guarantee, to
               the extent theretofore discharged, shall be reinstated in full
               force and effect.

                                       2
<PAGE>

          (f)  Each Guaranteeing Subsidiary shall not be entitled to any right
               of subrogation in relation to the Holders in respect of any
               obligations guaranteed hereby until payment in full of all
               obligations guaranteed hereby.


          (g)  As between the Guarantors, on the one hand, and the Holders and
               the Trustee, on the other hand, (x) the maturity of the
               obligations guaranteed hereby may be accelerated as provided in
               Article 6 of the Indenture for the purposes of this Guarantee,
               notwithstanding any stay, injunction or other prohibition
               preventing such acceleration in respect of the obligations
               guaranteed hereby, and (y) in the event of any declaration of
               acceleration of such obligations as provided in Article 6 of the
               Indenture, such obligations (whether or not due and payable)
               shall forthwith become due and payable by the Guarantors for the
               purpose of this Guarantee.


          (h)  The Guarantors shall have the right to seek contribution from any
               non-paying Guarantor so long as the exercise of such right does
               not impair the rights of the Holders under the Guarantee.


          (i)  Pursuant to Section 11.03 of the Indenture, after giving effect
               to any maximum amount and any other contingent and fixed
               liabilities that are relevant under any applicable Bankruptcy or
               fraudulent conveyance laws, and after giving effect to any
               collections from, rights to receive contribution from or payments
               made by or on behalf of any other Guarantor in respect of the
               obligations of such other Guarantor under Article 11 of the
               Indenture, the obligations of each Guaranteeing Subsidiary shall
               be limited to the maximum amount as will result in the
               obligations of such Guarantor under its Guarantee not
               constituting a fraudulent transfer or conveyance.

          3. SUBORDINATION. The obligations of each Guaranteeing Subsidiary
under its guarantee pursuant to this Supplemental Indenture shall be junior and
subordinated to the Senior Debt of each such Guaranteeing Subsidiary on the same
basis as the Notes are junior and subordinated to the Senior Debt of the
Company. For the purposes of the foregoing sentence, the Trustee and the Holders
shall have the right to receive and/or retain payments by each Guaranteeing
Subsidiary only at such time as they may receive and/or retain payments in
respect of the notes pursuant to the indenture, including article 10 thereof.

          4. EXECUTION AND DELIVERY. Each guaranteeing subsidiary agrees that
the guarantees shall remain in full force and effect notwithstanding any failure
to endorse on each note a notation of such guarantee.

          5. GUARANTEEING SUBSIDIARY MAY CONSOLIDATE, ETC. ON CERTAIN TERMS.
Each Guaranteeing Subsidiary will be subject to Section 11.05 of the Indenture.

          6. RELEASES. In the event of a sale or other disposition of all of the
assets of any guarantor, by way of merger, consolidation or otherwise, or a sale
or other disposition of all to the 

                                       3
<PAGE>

capital stock of any Guarantor, then such guarantor (in the event of a sale or
other disposition, by way of merger, consolidation or otherwise, of all of the
capital stock of such Guarantor) or the corporation acquiring the property (in
the event of a sale or other disposition of all or substantially all of the
assets of such Guarantor) will be released and relieved of any obligations under
its Guarantee; PROVIDED that the net proceeds of such sale or other disposition
are applied in accordance with the applicable provisions of the Indenture,
including without limitation section 4.10 of the Indenture. Upon delivery by the
Company to the Trustee of an Officers' Certificate and an Opinion of Counsel to
the effect that such sale or other disposition was made by the Company in
accordance with the provisions of the indenture, including without limitation
Section 4.10 of the Indenture, the Trustee shall execute any documents
reasonably required in order to evidence the release of any Guarantor from its
obligations under its Guarantee.

          (a)  Any Guarantor not released from its obligations under its
               Guarantee shall remain liable for the full amount of principal of
               and interest on the and for the other obligations of any
               guarantor under the indenture as provided in Article 10 of the
               indenture.

          7. NO RECOURSE AGAINST OTHERS. No past, present or future director,
officer, employee, incorporator, stockholder or agent of either Guaranteeing
Subsidiary, as such, shall have any liability for any obligations of the Company
or any Guaranteeing Subsidiary under the Notes, any Guarantees, the Indenture or
this Supplemental Indenture or for any claim based on, in respect of, or by
reason of, such obligations or their creation. Each Holder of the Notes by
accepting a Note waives and releases all such liability. The waiver and release
are part of the consideration for issuance of the Notes. Such waiver may not be
effective to waive liabilities under the federal securities laws and it is the
view of the Commission that such a waiver is against public policy.

          8. NEW YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF NEW YORK
SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE WITHOUT GIVING
EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE
APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

          9. COUNTERPARTS The parties may sign any number of copies of this
Supplemental Indenture. Each signed copy shall be an original, but all of them
together represent the same agreement.

          10. EFFECT OF HEADINGS. The Section headings herein are for
convenience only and shall not affect the construction hereof.

          11. THE TRUSTEE. The Trustee shall not be responsible in any manner
whatsoever for or in respect of the validity or sufficiency of this Supplemental
Indenture or for or in respect of the recitals contained herein, all of which
recitals are made solely by the Guaranteeing Subsidiaries and the Company.


                                       4

          IN WITNESS WHEREOF, the parties hereto have caused this Supplemental
Indenture to be duly executed and attested, all as of the date first above
written.

                      SECOND AMENDMENT TO CREDIT AGREEMENT


                  SECOND AMENDMENT TO CREDIT AGREEMENT (this "Amendment"), 
dated as of April 23, 1999, among TRANSDIGM HOLDING COMPANY, a Delaware

"Borrower"), the various lending institutions party to the Credit Agreement

                              W I T N E S S E T H :

                  WHEREAS, Holdings, the Borrower, the Lenders and the
Administrative Agent are parties to a Credit Agreement, dated as of December 3,
1998 (as amended through, but not including, the date hereof, the "Credit
Agreement"); and

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

                  NOW, THEREFORE, it is agreed:

I.       AMENDMENTS TO CREDIT AGREEMENT.

                  1. Section 1.01 of the Credit Agreement is hereby amended by
deleting clause (a) thereof in its entirety and inserting the following new
clause (a) in lieu thereof:

                  "(a) Subject to and upon the terms and conditions set forth
         herein, (A) each Lender with an A Term Loan Commitment on the Initial
         Borrowing Date severally agrees to make on such date, and (B) each
         Lender with an A Term Loan Commitment on the AR Acquisition Date
         severally agrees to make on such date, in each case, a term loan (each,
         an "A Term Loan" and, collectively, the "A Term Loans") to the
         Borrower, which A Term Loans: (i) shall be incurred pursuant to two
         single drawings, the first of which shall be on the Initial Borrowing
         Date and the second of which shall be on the AR Acquisition Date; (ii)
         shall be denominated in U.S. Dollars; (iii) except as hereafter
         provided, shall, at the option of the Borrower, be incurred and
         maintained as, and/or converted into, Base Rate Loans or Eurodollar
         Loans, provided that (x) all A Term Loans made as part of the same
         Borrowing shall, unless otherwise specifically provided herein, consist
         of A Term Loans of the same Type and (y) unless the Administrative
         Agent has determined that the Syndication Date has occurred (at which
         time this clause (y) shall no longer be applicable), no more than four
         Borrowings of A Term Loans to be maintained as Eurodollar Loans may be
         incurred prior to the 60th day after the Initial Borrowing Date (each
         of which Borrowings of Eurodollar Loans may only have an Interest
         Period of (A) in the case of the first two such Borrowings, seven days,
         and (B) in the case of the remaining two Borrowings, one month, and the
         first of which Borrowings may only be made on the Initial Borrowing
         Date or on or prior to the sixth Business Day after the


<PAGE>


         Initial Borrowing Date and with each such Borrowing made thereafter to
         be made only on the last day of the Interest Period of the immediately
         preceding Borrowing); and (iv) shall not exceed for any such Lender at
         the time of incurrence thereof on the Initial Borrowing Date or the AR
         Acquisition Date, as the case may be, that aggregate principal amount
         as is equal to the A Term Loan Commitment of such Lender as in effect
         on the Initial Borrowing Date or the AR Acquisition Date, as the case
         may be (before giving effect to any reductions thereto on such
         respective date pursuant to Section 3.03(b)). Once repaid, A Term Loans
         incurred hereunder may not be reborrowed."

                  2. Section 1.01 of the Credit Agreement is hereby further
amended by deleting clause (b) thereof in its entirety and inserting the
following new clause (b) in lieu thereof:

                  "(b) Subject to and upon the terms and conditions set forth
         herein, (A) each Lender with a B Term Loan Commitment on the Initial
         Borrowing Date severally agrees to make on such date, and (B) each
         Lender with a B Term Loan Commitment on the AR Acquisition Date
         severally agrees to make on such date, in each case, a term loan (each,
         a "B Term Loan" and, collectively, the "B Term Loans" and, together
         with the A Term Loans, the "Term Loans") to the Borrower, which B Term
         Loans: (i) shall be incurred pursuant to two single drawings, the first
         of which shall be on the Initial Borrowing Date and the second of which
         shall be on the AR Acquisition Date; (ii) shall be denominated in U.S.
         Dollars; (iii) except as hereafter provided, shall, at the option of
         the Borrower, be incurred and maintained as, and/or converted into,
         Base Rate Loans or Eurodollar Loans, provided that (x) all B Term Loans
         made as part of the same Borrowing shall, unless otherwise specifically
         provided herein, consist of B Term Loans of the same Type and (y)
         unless the Administrative Agent has determined that the Syndication
         Date has occurred (at which time this clause (y) shall no longer be
         applicable), no more than four Borrowings of B Term Loans to be
         maintained as Eurodollar Loans may be incurred prior to the 60th day
         after the Initial Borrowing Date (each of which Borrowings of
         Eurodollar Loans (I) may only have the same Interest Period as is then
         permitted for a Borrowing of A Term Loans that are maintained as
         Eurodollar Loans and (II) shall begin and end on the same day as a
         Borrowing of A Term Loans that are maintained as Eurodollar Loans); and
         (iv) shall not exceed for any such Lender at the time of incurrence
         thereof on the Initial Borrowing Date or the AR Acquisition Date, as
         the case may be, that aggregate principal amount as is equal to the B
         Term Loan Commitment of such Lender as in effect on the Initial
         Borrowing Date or the AR Acquisition Date, as the case may be (before
         giving effect to any reductions thereto on such respective date
         pursuant to Section 3.03(c)). Once repaid, B Term Loans incurred
         hereunder may not be reborrowed."

                  3. Section 3.03 of the Credit Agreement is hereby amended by
deleting clauses (b) and (c) thereof in their entirety and inserting the
following new clauses (b) and (c), respectively, in lieu thereof:

                  "(b) In addition to any other mandatory commitment reductions
         pursuant to this Section 3.03, the Total A Term Loan Commitment (and 
         the A Term Loan 


                                       2
<PAGE>


         Commitment of each Lender) shall terminate in its entirety on the 
         Initial Borrowing Date (after giving effect to the incurrence of A 
         Term Loans on such date); provided that, notwithstanding the 
         foregoing, the portion of the Total A Term Loan Commitment effected 
         pursuant to the Second Amendment shall terminate in its entirety on 
         the AR Acquisition Date (after giving effect to the incurrence of A 
         Term Loans on such date).

                  (c) In addition to any other mandatory commitment reductions
         pursuant to this Section 3.03, the Total B Term Loan Commitment (and
         the B Term Loan Commitment of each Lender) shall terminate in its
         entirety on the Initial Borrowing Date (after giving effect to the
         incurrence of B Term Loans on such date); provided that,
         notwithstanding the foregoing, the portion of the Total B Term Loan
         Commitment effected pursuant to the Second Amendment shall terminate in
         its entirety on the AR Acquisition Date (after giving effect to the
         incurrence of B Term Loans on such date)."

deleting the table appearing in clause (b) thereof in its entirety and inserting
the following new table in lieu thereof:

<PAGE>


         appropriate filing offices of each jurisdiction as may be necessary or,

         the security interests in all of the Collateral acquired pursuant to
         the AR Acquisition, (B) certified copies of Requests for Information or
         Copies (Form UCC-11), or equivalent reports, listing all effective
         financing statements that name AR Holdings or any of its Subsidiaries
         as debtor and that are filed in the jurisdictions referred to in clause
         (A) above, together with copies of such other financing statements that
         name AR Holdings or any of its Subsidiaries as debtors (none of which
         shall cover the Collateral except to the extent evidencing Permitted
         Liens or in respect of which the Collateral Agent shall have received
         appropriate termination statements executed by the secured party
         thereunder), (C) evidence of the completion of all other recordings and

         the Security Documents, and (D) evidence (including appropriate pay-off

Notwithstanding anything to the contrary contained above or elsewhere in this
Second Amendment, unless both the Second Amendment Effective Date and the AR
Acquisition Date occur on or prior to March 31, 1999, the Second Amendment
Effective Date shall not thereafter occur and this Amendment shall be of no
further force or effect. Unless the Administrative Agent has received actual
notice from any Lender that the conditions contained above have not been met,
upon the satisfaction of the condition described in clause (i) of the
immediately preceding sentence and upon the Administrative Agent's good faith
determination that the other conditions described above have been met, the
Second Amendment Effective Date shall be deemed to have occurred, regardless of
any subsequent determination that one or more of the conditions thereto had not
been met (although the occurrence of the Second Amendment Effective Date shall
not release the Borrower from any liability for failure to satisfy one or more
of the applicable conditions specified above). The Administrative Agent will
give the Borrower and each Lender prompt notice of the occurrence of the Second
Amendment Effective Date. The acceptance by the Borrower of the proceeds of the
Loans on the AR Acquisition Date shall be deemed to constitute a representation
and warranty by the Borrower (including, without limitation, for purposes of
Section 10.02 of the Credit Agreement) to the effect that all conditions
contained above in this Paragraph 6 have been satisfied as of the Second
Amendment Effective Date.

                  7. From and after the Second Amendment Effective Date, all
references in the Credit Agreement and each of the other Credit Documents to the
Credit Agreement shall be deemed to be references to the Credit Agreement as
amended hereby.

California corporation ("ZMP"), and Adams Rite Aerospace, Inc., a California 
corporation ("Adams Rite Aerospace" and, together with Holdings, Marathon and 
ZMP, the "Guarantors"), in each case, under the Securities Act of 1933, as 
amended (the "Act"), on Form S-4 filed with the Securities and Exchange 
Commission (the "Commission") on January 29, 1999 (File No. 333-50219), as 
the same has been amended on or prior to the date hereof, and as it may be 
further amended (collectively the "Registration Statement"), you have 
requested our opinion with respect to the matters set forth below. The New 
Notes and the New Guarantees will be issued pursuant to an indenture, dated 
as of December 3, 1998, among the Company, Holdings and Marathon and State 
Street Bank and Trust Company, as trustee (the "Trustee"), as supplemented by 
a supplemental indenture, dated April 23, 1999, among the Company, the 
Guarantors and the Trustee (such indenture, as supplemented by such 
supplemental indenture, the "Indenture"). The New Notes and the New 
Guarantees will be issued in exchange for the Company's outstanding 10-3/8% 
Senior Subordinated Notes due 2008 (the "Old Notes") and the guarantees of 
the Old Notes by the Guarantors (the "Old Guarantees") on the terms set forth 
in the prospectus contained in the Registration Statement and the Letter of 
Transmittal filed as an exhibit thereto (the "Exchange Offer").

          In our capacity as your special counsel, we are familiar with the
proceedings taken and proposed to be taken by the Company and the Guarantors in
connection with the authorization and issuance of the New Notes and the New
Guarantees, respectively, and for the purposes of this opinion, have assumed
such proceedings will be timely completed in the manner currently proposed. In
addition, we have made such legal and factual examinations and inquiries,
including an examination of originals or copies certified or otherwise
identified to our satisfaction of such documents, corporate records and
instruments, as we have deemed necessary or appropriate for purposes of this
opinion.

          In our examination, we have assumed the genuineness of all signatures,
the authenticity of all documents submitted to us as originals and the
conformity to authentic original documents of all documents submitted to us as
copies. As to facts material to the opinions, statements and assumptions
expressed herein, we have, with your consent, relied upon oral or written
statements and representations of officers and other representatives of the
Company, the Guarantors and others.

          We are opining herein as to the effect on the subject transaction only
of the federal laws of the United States, the internal laws of the States of New
York and California and the General Corporation Law of the State of Delaware,
and we express no opinion with respect to the applicability thereto, or the
effect thereon, of the laws of any other jurisdiction or, in the case of

Delaware, any other laws, or as to any matters of municipal law or the laws of
any other local agencies within any state.

          Subject to the foregoing and the other matters set forth herein, it is
our opinion that, as of the date hereof:

          (1) The New Notes to be exchanged for the Old Notes pursuant to the
Exchange Offer have been duly authorized by all necessary corporate action on
the part of the Company, and, when duly executed, issued and authenticated in
accordance with the terms of the Exchange Offer and the Indenture and exchanged
for the Old Notes in accordance with the terms of the Exchange Offer, will be
the legally valid and binding obligations of the Company, enforceable against
the Company in accordance with their terms.

          (2) Each of the New Guarantees has been duly authorized by all
necessary corporate action on the part of the Guarantors, and, when duly
executed and endorsed on the New Notes in accordance with the terms of the
Indenture and upon the due execution, issuance and authentication of the New
Notes in accordance with the terms of the Exchange Offer and the Indenture and
exchange of the New Notes for the Old Notes in accordance with the terms of the
Exchange Offer, will be the legally valid and binding obligation of each of the
Guarantors, enforceable against each of the Guarantors in accordance with its
terms.

          The opinions rendered in paragraphs 1 and 2 relating to the
enforceability of the New Notes and the New Guarantees are subject to the
following exceptions, limitations and qualifications: (i) the effect of
bankruptcy, insolvency, reorganization, moratorium or other similar laws now or
hereafter in effect relating to or affecting the rights and remedies of
creditors; (ii) the effect of general principles of equity, whether enforcement
is considered in a proceeding in equity or at law, and the discretion of the
court before which any proceeding therefor may be brought and (iii) we express
no opinion concerning the enforceability of the waiver of rights or defenses
contained in Section 4.06 of the Indenture.

          To the extent that the obligations of the Company or any of the
Guarantors under the Indenture, the New Notes or the New Guarantees may be
dependent upon such matters, we have assumed for purposes of this opinion that
(i) the Trustee (a) is duly organized, validly existing and in good standing
under the laws of its jurisdiction of organization; (b) has the requisite
organizational and legal power and authority to perform its obligations under
the Indenture; (c) is duly qualified to engage in the activities contemplated by
the Indenture; (d) has duly authorized, executed and delivered the Indenture and
(e) has complied with any applicable requirement to file returns and pay taxes
under the Franchise Tax Law of the State of California; (ii) the Indenture is
the legally valid and binding agreement of the Trustee, enforceable against

the Trustee in accordance with its terms; and (iii) that the Trustee is in
compliance, generally and with respect to acting as Trustee under the Indenture,
with all applicable laws and regulations. We have also assumed, with your
consent, that the choice of law provisions in the Indenture would be enforced by
any court in which enforcement thereof might be sought.

the Company and the Guarantors under the Indenture, the New Notes and the New
Guarantees, as applicable, of Sections 547 and 548 of the Bankruptcy Code or
applicable state law (including, without limitation, Article 10 of the New York
Debtor & Creditor Law) relating to preferences and fraudulent transfers and
