                                     PART I

ITEM 1. BUSINESS

     During 1999, Ducommun Incorporated ("Ducommun"), through its subsidiaries
(collectively, the "Company"), manufactured components and assemblies
principally for domestic and foreign commercial and military aircraft and space
programs. Domestic commercial aircraft programs include the Boeing 717, 737,
737NG, 747, 757, 767 and 777. Foreign commercial aircraft programs include the
Airbus Industrie A330, A340 and A340-600 aircraft, Bombardier Business and
Regional Jets and Dash 8. Major military aircraft programs include the Boeing
C-17, F-15 and F-18, Lockheed Martin F-16 and C-130, various Sikorsky, Bell,
Boeing and Augusta helicopter programs, and advanced development programs. The
Company is a subcontractor to Lockheed Martin on the Space Shuttle external tank
and a supplier of components for the Space Shuttle Orbitor, as well as for Space
Station Freedom. The Company manufactures components for Atlas/Centaur, Delta
and Titan expendable launch vehicles, Kistler K-1 reusable launch vehicles, and
various telecommunications satellites.

     In November 1999, Ducommun, through a wholly-owned subsidiary, acquired the
assets and assumed certain liabilities of Parsons Precision Products, Inc.
("Parsons"). In April 1999, Ducommun acquired the capital stock of Sheet Metal
Specialties Company ("SMS"). In August 1998, Ducommun sold the capital stock of
3dbm, Inc. ("3dbm"). In June 1998, Ducommun Technologies, Inc., a subsidiary of
Ducommun, acquired the capital stock of American Electronics, Inc. ("AEI").


Aerochem, Inc.

     Ducommun's subsidiary, Aerochem, Inc. ("Aerochem"), is a major supplier of
close tolerance chemical milling services for the aerospace and aircraft
industries. Chemical milling removes material in specific patterns to reduce
weight in areas where full material thickness is not required. This
sophisticated etching process enables Aerochem to produce lightweight,
high-strength designs that would be impractical to produce by conventional
means. Jet engine components, wing leading edges and fuselage skins are examples
of products that require chemical milling.

     Aerochem offers production-scale chemical milling on aluminum, titanium,
steel, nickel-base and super alloys. Aerochem also specializes in very large and
complex parts up to 50 feet long. Management believes that Aerochem is the
largest independent supplier of chemical milling services in the United States.
Many of the parts chemically milled by Aerochem are formed and machined by
AHF-Ducommun Incorporated.


AHF-Ducommun Incorporated

     AHF-Ducommun Incorporated ("AHF"), another Ducommun subsidiary, supplies
aircraft and aerospace prime contractors with engineering, manufacturing and
testing of complex components using stretch forming and thermal forming
processes and computer-controlled machining. Stretch forming is a process for
manufacturing large, complex


                                       3
<PAGE>   4

structural shapes primarily from aluminum sheet metal extrusions. AHF has some
of the largest and most sophisticated stretch forming presses in the United
States. Thermal forming is a metal working process conducted at high temperature
for manufacturing close tolerance titanium components. AHF designs and
manufactures the tooling required for the production of parts in both forming
processes. Certain components manufactured by AHF are machined with precision
milling equipment designed and constructed by AHF. AHF also employs
computer-aided design/manufacturing systems with three 5-axis gantry profile
milling machines and three 5-axis numerically-controlled routers to provide
computer-controlled machining and inspection of complex parts up to 100 feet
long.

        AHF has an integrated operation offering a broad range of capabilities.
From the design specifications of a customer, AHF is able to engineer,
manufacture, test and deliver the desired finished components. This process
depends on the skillful execution of several complex subtasks, including the
design and construction of special equipment. Management believes that the
ability of AHF to provide a full range of integrated capabilities represents a
competitive advantage.

     In November 1999, Ducommun, through a wholly-owned subsidiary, acquired the
assets and assumed certain liabilities of Parsons. Parsons is a leading
manufacturer of complex titanium hot-formed subassemblies and components for
commercial and military aerospace applications. Parsons' management team
remained with the Company at its existing Parsons, Kansas facility and reports
through AHF-Ducommun Incorporated.


Brice Manufacturing Company, Inc.

     Brice Manufacturing Company, Inc. ("Brice"), a subsidiary of Ducommun, is
an after-market supplier of aircraft seating products to many of the world's
largest commercial airlines. Products supplied by Brice include plastic and
metal seat parts, overhauled and refurbished seats, components for installation
of in-flight entertainment equipment, and other cabin interior components for
commercial aircraft.

     In 1998, Brice introduced an original equipment manufacture ("OEM") 16G
aircraft seat. This new aircraft seat represents Brice's first major OEM
product.


Ducommun Technologies, Inc. (formerly Jay-El Products, Inc.)

     Ducommun Technologies, Inc. ("DTI"), a subsidiary of Ducommun, develops,
designs and manufactures illuminated switches, switch assemblies and keyboard
panels used in many military aircraft, helicopter, commercial aircraft and
spacecraft programs, as well as ground support equipment and naval vessels. DTI
manufactures switches and panels where high reliability is a prerequisite.
Keyboard panels are lighted, feature push button switches, and are available
with sunlight readable displays. Some of the keyboard panels and illuminated
switches manufactured by DTI for military applications are night vision
goggle-compatible.

     DTI also develops, designs and manufactures microwave switches, filters and
other components used principally on commercial and military aircraft and
telecommunications

                                       4
<PAGE>   5

satellites. DTI has developed several new products that apply its existing
microwave technology to nonaerospace markets, including the wireless
telecommunications industry.

     In June 1998, DTI acquired the capital stock of AEI. AEI is a leading
manufacturer of high precision actuators, stepper motors, fractional horsepower
motors and resolvers principally for commercial and military space
applications.


MechTronics of Arizona Corp.

     MechTronics is a leading manufacturer of mechanical and electromechanical
enclosure products for the defense electronics and commercial aviation markets.
MechTronics has a fully integrated manufacturing capability, including
engineering, fabrication, machining, assembly, electronic integration and
related processes. MechTronics' products include sophisticated radar enclosures,
aircraft avionics racks and shipboard communications and control enclosures.

     In April 1999, Ducommun acquired the capital stock of SMS. SMS is a
manufacturer of subassemblies for commercial and military aerospace
applications. SMS remained at its existing Chatsworth, California facility and
reports through MechTronics of Arizona Corp.


3dbm, Inc.

     In August 1998, Ducommun sold the capital stock of its wireless
communications subsidiary, 3dbm, Inc. ("3dbm"). The Company sold 3dbm because
the level of investment required to ensure the long-term viability of 3dbm in
the wireless system infrastructure business was more than the Company was
willing to commit.


Defense and Space Programs

     A major portion of sales is derived from United States government defense
programs and space programs. Approximately 31 percent of 1999 sales were related
to defense programs and approximately 11 percent of 1999 sales were related to
space programs. These programs could be adversely affected by reductions in
defense spending and other government budgetary pressures which would result in
reductions, delays or stretch-outs of existing and future programs. In addition,
many of the Company's contracts covering defense and space programs are subject
to termination at the convenience of the customer (as well as for default). In
the event of termination for convenience, the customer generally is required to
pay the costs incurred by the Company and certain other fees through the date of
termination.


Commercial Programs

     Approximately 58 percent of 1999 sales were related to commercial aircraft
programs, and nonaerospace commercial applications. The Company's commercial
sales depend substantially on aircraft manufacturer's production rates, which in
turn depend upon deliveries of new aircraft. Deliveries of new aircraft by
aircraft manufacturers are dependent on the financial capacity of the airlines
and leasing companies to purchase the aircraft. Sales of commercial aircraft
could be affected as a result of changes in new aircraft orders, or the

                                       5
<PAGE>   6

cancellation or deferral by airlines of purchases of ordered aircraft. The
Company's sales for commercial aircraft programs also could be affected by
changes in its customers' inventory levels and changes in its customers'
aircraft production build rates.


Major Customers

     The Company had substantial sales to Boeing, Lockheed Martin and Raytheon.
During 1999, sales to Boeing were $40,310,000, or 28% of total sales; sales to
Lockheed Martin were $15,470,000, or 11% of total sales, and sales to Raytheon
were $10,138,000, or 7% of total sales. Sales to Boeing, Lockheed Martin and
Raytheon are diversified over a number of different commercial, military and
space programs.


Competition

     The Company competes with various companies, some of which are
substantially larger and have greater financial, technical and personnel
resources. The Company's ability to compete depends on the quality of goods and
services, competitive pricing and the ability to solve specific customer
problems.


Backlog

     At December 31, 1999, backlog believed to be firm was approximately
$213,100,000, compared to $138,200,000 at December 31, 1998. Approximately
$95,000,000 of total backlog is expected to be delivered during 2000.


Environmental Matters and Legal

     Aerochem uses various acid and alkaline solutions in the chemical milling
process, resulting in potential environmental hazards. Despite existing waste
recovery systems and continuing capital expenditures for waste reduction and
management, at least for the immediate future, Aerochem will remain dependent on
the availability and cost of remote hazardous waste disposal sites or other
alternative methods of disposal.

     The Aerochem facility located in El Mirage, California has been directed by
California environmental agencies to investigate and take corrective action for
groundwater contamination. Based upon currently available information, the
Company has established a provision for the cost of such investigation and
corrective action. Aerochem expects to spend approximately $1 million for future
investigation and corrective action for groundwater contamination at its El
Mirage location. However, the Company's ultimate liability in connection with
the contamination will depend upon a number of factors, including changes in
existing laws and regulations, and the design and cost of the construction,
operation and maintenance of the corrective action.

     Ducommun's other subsidiaries are also subject to environmental laws and
regulations. However, the quantities of hazardous materials handled, hazardous
wastes generated and air emissions released by these subsidiaries are relatively
small.

                                       6
<PAGE>   7

     The Company anticipates that capital expenditures will continue to be
required for the foreseeable future to upgrade and maintain its environmental
compliance efforts. The Company does not expect to spend a material amount on
capital expenditures for environmental compliance during 2000.

     In the normal course of business, Ducommun and its subsidiaries are
defendants in certain other litigation, claims and inquiries, including matters
relating to environmental laws. In addition, the Company makes various
commitments and incurs contingent liabilities. While it is not feasible to
predict the outcome of these matters, the Company does not presently expect that
any sum it may be required to pay in connection with these matters would have a
material adverse effect on its consolidated financial position or results of
operations.


Employees

     At December 31, 1999, the Company employed 1,202 persons.


Business Segment Information

     The Company operates principally in only one business segment.


Information About Foreign and Domestic Operations and Export Sales

     In 1999, 1998 and 1997, foreign sales to manufacturers worldwide were
$28,313,000, $29,007,000 and $29,978,000, respectively.

     The amounts of revenue, profitability and identifiable assets attributable
to foreign operations are not material when compared with the revenue,
profitability and identifiable assets attributed to United States domestic
operations during 1999, 1998 and 1997. The Company had no sales to a foreign
country greater than 4.2% of total sales in 1999, 1998 and 1997.

     The Company is not subject to any foreign currency risks since all sales
are made in United States dollars.


ITEM 2. PROPERTIES

     The Company occupies approximately 17 facilities with a total office and
manufacturing area of over 956,000 square feet, including both owned and leased
properties. At December 31, 1999, facilities which were in excess of 60,000
square feet each were occupied as follows:

</TABLE>


     The Company's facilities are, for the most part, fully utilized, although
excess capacity exists from time to time based on product mix and demand.
Management believes that these properties are in good condition and suitable for
their present use.

     Although the Company maintains standard property casualty insurance
covering its properties, the Company does not carry any earthquake insurance
because of the cost of such insurance. Most of the Company's properties are
located in Southern California, an area subject to frequent and sometimes severe
earthquake activity.


ITEM 3. LEGAL PROCEEDINGS

     On October 25, 1999, Com Dev Consulting Ltd. ("Com Dev") filed a complaint,
which was subsequently amended on December 22, 1999, against Ducommun and
certain officers of the Company in the United States Court for the Central
District of California. The complaint alleged violation of the federal
securities laws, intentional misrepresentation, negligent misrepresentation,
unfair business practices and breach of contract in connection with the sale of
the capital stock of 3dbm by Ducommun to Com Dev in August 1998, and sought
unspecified general and punitive damages from the defendants. On February 3,
2000, the United States District Court dismissed the complaint without
prejudice. The Company intends to vigorously defend the matter if Com Dev
attempts to reassert its claims. While it is not feasible to predict the outcome
of this matter, the Company presently believes that the final resolution of the
matter will not have a material adverse effect on its consolidated financial
position or results of operations.

of Ducommun Incorporated


Our audits of the consolidated financial statements referred to in our report
dated February 17, 2000 appearing in the 1999 Annual Report to Shareholders of
Ducommun Incorporated (which report and consolidated financial statements are
incorporated by reference in this Annual Report on Form 10-K) also included an
audit of the financial statement schedule listed in Item 14(a)(2) of this Form
10-K. In our opinion, this financial statement schedule presents fairly, in all
material respects, the information set forth therein when read in conjunction
with the related consolidated financial statements.

     Section 3. Notice of Meetings. Except as otherwise required by law, notice
of meetings of stockholders, annual or special, shall be given to stockholders
entitled to vote thereat by the Secretary or an Assistant Secretary or other
person charged with that duty not less than ten (10) nor more than sixty (60)
days before the date of any such meeting. Such notice may be printed,
typewritten, or in handwriting, and may be given to any stockholder either
personally or by sending a copy of the notice through the mail, or by telegram,
charges prepaid, to his address appearing on the books of the Corporation or
supplied by him to the Corporation for the purpose of notice. Except as
otherwise expressly required by law, no publication of any notice of a meeting
of the stockholders shall be required. Every notice of a meeting of the
stockholders shall state the place, date and hour of the meeting, and in the
case of a special meeting, the purpose or purposes for which the meeting is
called.

     Section 4. Place of Meetings. All meetings of the stockholders shall be
held at the principal office of the Corporation in the State of California or at
such other place within or without the State of Delaware as the Board of
Directors may from time to time designate.

consist of stockholders holding a majority of the voting power of the shares of
this Corporation outstanding and entitled to vote thereat, represented either in
person or by proxy, except as otherwise specifically provided by law or in the
Certificate of Incorporation. In the absence of a quorum, any meeting of
stockholders may be adjourned from time to time by the vote of a majority of the
voting stock, the holders of which are either present in person or represented
by proxy thereat. The stockholders present at a meeting at which a quorum is
present may continue to do business until adjournment, notwithstanding the
withdrawal of enough stockholders to leave less than a quorum.

     Section 6. Adjournments. When a meeting is adjourned for thirty (30) days
or more, notice of the adjourned meeting shall be given as in the case of the
original meeting, but when a meeting is adjourned for less than thirty (30) days
it is not necessary to give any notice of the time and place of the adjourned
meeting or of the business to be transacted thereat other than by announcement
at the meeting at which the adjournment is taken. At any such adjourned meeting
at which a quorum shall be present, any business may be transacted which might
have been transacted at the meeting as originally noticed.

     Section 7. Organization. The Chairman of the Board of Directors, or, in his
absence, the President, or in the absence of the Chairman of the Board of
Directors and the President, the Executive Vice President, a Senior Vice
President or a Vice President shall call meetings of stockholders to order, and

Board of Directors, the President, the Executive Vice President, any Senior Vice
President and the Vice Presidents, the stockholders shall appoint a Chairman for
such meeting. The Secretary of the Corporation shall act as Secretary at all
meetings of the stockholders, but in the absence of the Secretary at any meeting
of the stockholders, the presiding officer may appoint any person to act as
Secretary of the meeting.

     Section 8. Voting

which shall have been held by him and registered in his name on the books of the
Corporation:

                                       3
<PAGE>   3

               (i) on the date fixed pursuant to ARTICLE II, Section 11 of these
          Bylaws as the record date for the determination of stockholders
          entitled to notice of and to vote at such meeting, or

               (ii) if no such record date shall have been so fixed, then (a) at
          the close of business on the day next preceding the day on which
          notice of the meeting shall be given, or (b) if notice of the meeting
          shall be waived, at the close of business on the day next preceding
          the day on which the meeting shall be held.

          (b) Shares of its own stock belonging to the Corporation shall not be
entitled to vote. Persons holding in a fiduciary capacity stock of the
Corporation shall be entitled to vote such stock so held. A person whose stock
is pledged shall be entitled to vote such stock, unless in the transfer by the
pledger on the books of the Corporation he shall have expressly empowered the
pledgee to vote thereon, in which case only the pledgee, or his proxy, may
represent such stock and vote thereon. Stock having voting power standing of
record in the names of two or more persons, whether fiduciaries, members of a
partnership, joint tenants, tenants in common, tenants by the entirety or
otherwise, or with respect to which two or more persons have the same fiduciary
relationship, shall be voted in accordance with the provisions of the General
Corporation Law of the State of Delaware.

          (c) Any such voting rights may be exercised by the stockholder
entitled thereto in person or by his proxy appointed by an instrument in
writing, subscribed by such stockholder or by his attorney thereunto authorized
and delivered to the Secretary of the meeting; provided, however, that no proxy
shall be voted or acted upon after three years from its date unless said proxy
shall provide for a longer period. The attendance at any meeting of a
stockholder who may theretofore have given a proxy shall not have the effect of
revoking the same unless he shall in writing so notify the Secretary of the
meeting prior to the voting of the proxy. At any meeting of the stockholders all
matters, except as otherwise provided in the Certificate of Incorporation, these
Bylaws or bylaw, shall be decided by the vote of majority in voting interest of
the stockholders present in person or by proxy and entitled to vote thereat and
thereon, a quorum being present . The vote at any meeting of the stockholders on
any question need not be by ballot, unless so directed by the Chairman of the
meeting. On a vote by ballot each ballot shall be signed by the stockholder
voting, or by his proxy, if there be such proxy, and it shall state the number
of shares voted.

     Section 9. Inspectors of Election. In advance of any meeting of
stockholders, the Board of Directors may appoint inspectors of election to act
at such meeting or any adjournment thereof. If inspectors of election be not so
appointed, the Chairman of any such meeting may make such appointment at the
meeting. The number of inspectors shall be either one or three.

     Section 10. Consent of Absentees. The transactions of any meeting of
stockholders, either annual or special, however called and noticed, shall be as
valid as though had at a meeting duly held after regular call and notice, if a
quorum be present either in person or by proxy, and if, either before or after
the meeting, each of the stockholders entitled to vote, not present in person or
by proxy, signs a written waiver of notice. All such waivers shall be filed with
the corporate records or made a part of the minutes of the meeting. Attendance
of a person at a meeting of stockholders shall constitute a waiver of notice of
such meeting, except when the stockholder attends the meeting for the express
purpose of objecting, at the beginning of the meeting, to the transaction of any
business because the meeting is not lawfully called or convened.

of and to vote at any meeting of stockholders, or for the determination of the
stockholders entitled to receive any dividend or distribution or any allotment
of rights, or to exercise rights in respect to any change, conversion or
exchange of shares. The record date so fixed shall not be more than sixty (60)
nor less than ten (10) days before the date of any such meeting, nor more than
sixty (60) days prior to any other action. When a record date is so fixed, only
stockholders who are such of record on that date are entitled to notice of and
to vote at the meeting or to receive the dividend, distribution, or allotment of
rights, or to exercise the rights, as the case may be, notwithstanding any
transfer of any shares on the books of the Corporation after the record date.
The Board of Directors may close the books of the Corporation against transfers
of shares during the whole or any part of a period not more than sixty (60) days
prior to the date of a stockholders' meeting, the date when the right to any
dividend, distribution, or allotment of rights vests, or the effective date of
any change, conversion or exchange of shares. A determination of stockholders
entitled to notice of or to vote at a meeting of stockholders shall apply to any
adjournment of such meeting; provided, however, that the Board of Directors may
fix a new record date for the adjourned meeting.

     Section 12. Conduct of Meetings. The Chairman of the Board of Directors
shall have complete authority to establish rules of conduct governing all
meetings of stockholders. These rules may include, but shall not be limited to,
rules related to attendance, questions from the audience and similar matters.
Notwithstanding the above, the nomination at any meeting of stockholders of any
person to serve as a Director shall not be valid unless (i) the nomination of
such person has been approved by resolution of the Board of Directors of the
Corporation, or (ii) notice of the nomination of such person has been delivered
to the Secretary of the Corporation not less than 120 days prior to the date of
the meeting of stockholders.

                                 Indemnification

     Section 1. Indemnification of Directors and Officers. The Corporation
shall, to the fullest extent permitted by law, 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,

                                       12
<PAGE>   12

criminal, administrative or investigative (including without limitation any
action by or in the right of the Corporation) by reason of the fact that he is
or was a Director or Officer of the Corporation, or is or was serving at the
request of the Corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, against
expenses (including attorneys' fees) judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The termination of any
action, suit or proceeding by judgment, order, settlement, conviction, or upon a
plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, that he had
reasonable cause to believe that his conduct was unlawful. The right of
indemnity provided herein shall not be exclusive, and the Corporation may
provide indemnification to any person, by agreement or otherwise, on such terms
and conditions as the Board of Directors may approve. Any agreement for
indemnification of any Director, Officer, employee or other person may provide
indemnification rights which are broader or otherwise different from those set
forth herein.

     Section 2. Insurance. The Corporation may purchase and maintain insurance
on behalf of any person who is or was a Director, Officer, employee or agent of

          2.2 Paragraph 2.2 of the Agreement is amended in its entirety to read
as follows:

               "2.2 Letters of Credit. Subject to the terms and conditions
     hereof, at any time and from time to time from the Restatement Date through
     the Banking Day immediately preceding the Termination Date, Bank shall
     issue such Letters of Credit as Borrower may request, provided that, upon
     giving effect to such Letter of Credit (i) Total Outstandings shall not
     exceed the Line Commitment, and (ii) the Letter of Credit Obligations shall
     not exceed $1,000,000 for standby Letters of Credit. Unless Bank otherwise
     consents in writing, the term of any standby Letter of Credit shall not
     exceed 24 months, and shall in no event in any case extend more than 12
     months beyond the Termination Date. No Letter of Credit shall be issued
     except to the extent reasonably necessary in the ordinary course of the
     business of Borrower or its Subsidiaries, and no Letter of Credit shall be
     issued in any event to support any workers' compensation obligation of
     Borrower or its Subsidiaries. Unless otherwise agreed to by Bank, the face
     amount of any Letter of Credit shall not be less than $25,000.

Borrower agrees:

               (a) if there is a default under this Agreement, to immediately
     prepay and make Bank whole for any outstanding Letters of Credit.

               (b) the issuance of any Letter of Credit and any amendment to a
     Letter of Credit is subject to Bank's written approval and must be in form
     and content satisfactory to Bank and in favor of a beneficiary acceptable
     to Bank.

               (c) to sign Bank's form Application and Agreement for Standby
     Letter of Credit with respect to each Letter of Credit.

               (d) to allow Bank to automatically charge its checking account
     for applicable fees, discounts, and other charges.

               (e) to pay Bank a non-refundable fee equal to 1.50% per annum of
     the outstanding undrawn amount of each standby Letter of Credit, payable
     annually in advance, calculated on the basis of the face amount outstanding
     on the day the fee is calculated.

               (f) to pay to Bank the amount of any payment made or to be made
     by Bank under any Letter of Credit, upon Bank's demand; and, if Borrower
     fails to make any such payment, Bank may, but is not required to, without
     notice to or the consent of Borrower, make a

<PAGE>   3

     Loan in an aggregate amount equal to the amount paid by Bank on the
     relevant Letter of Credit, whether or not the same would cause Total
     Outstandings to exceed the Line Commitment (without waiving the obligation
     of Borrower to reduce Total Outstandings to an amount less than or equal to
     the Line Commitment) and, for this purpose, the conditions precedent set
     forth in Article 8 and the amount limitations set forth in Paragraph 2.1
     shall not apply. The proceeds of such Loan shall be paid to Bank to
     reimburse it for the payment made by it under the Letter of Credit.

               (g) Subject to the next sentence, a Letter of Credit may be
     requested pursuant to this Paragraph 2.2 for the account of Borrower or for
     the account of any Subsidiary of Borrower. To the extent that a Subsidiary
     of Borrower is the account party under any Letter of Credit, Borrower
     hereby guarantees the payment and performance of such Subsidiary with
     respect to any Obligation of such Subsidiary relating to such Letter of
     Credit, and agrees to deliver to Bank, duly executed and in form and
     content acceptable to Bank, a duly executed continuing guaranty further
     evidencing the foregoing guaranty, together with a resolution or other
     evidence of the corporate authority of Borrower to execute, perform and
     deliver such continuing guaranty.

          2.3 In Paragraph 4.13 of the Agreement, the phrase ", or in connection
     with the issuance of any Letter of Credit," is added in the third line of
     said paragraph immediately following the word "Loan."

          2.4 Paragraph 5.9 of the Agreement is amended in its entirety to read
     as follows:

               "5.9 Use of Proceeds. Use the proceeds of the Line of Credit for
          the following purposes only: (i) for working capital purposes of
          Borrower and its Subsidiaries, (ii) to issue Letters of Credit, (iii)
          for other lawful corporate purposes in the ordinary course of
          business, and (iv) to finance Permitted Acquisitions."

          2.5 Paragraph 6.3 of the Agreement is amended by deleting the period
     at the end of the paragraph and adding the following:

               "; provided, further, however, that the amount of the following
          transactions shall not be included in calculating the amount of
          redemptions or repurchases of shares permitted under clause (c) of
          this Paragraph 6.3: common stock repurchases that (i) occurred prior
          to January 1, 1999 or (ii) are financed exclusively from balance sheet
          cash derived from sources other than Loans under this Agreement."

          2.6 All references to Letters of Credit in Paragraph 9.2 of the
     Agreement, previously deleted pursuant to Paragraph 2.9 of the Second
     Amendment, are hereby fully reinstated.

          2.7 All references to Letters of Credit in Paragraph 10.8 of the
     Agreement, previously deleted pursuant to Paragraph 2.10 of the Second
     Amendment, are hereby fully reinstated.

     3. Representations and Warranties. When the Borrower signs this Amendment,
the Borrower represents and warrants to the Bank that: (a) there is no event
which is, or with notice or lapse of time or both would be, a default under the
Agreement, (b) the representations and warranties in the Agreement are true as

Amendment is within the Borrower's powers, has been duly authorized, and does
not conflict with any of the Borrower's organizational papers, and (d) this

     4. Conditions. This Amendment will be effective when the Bank receives the
following items, in form and content acceptable to the Bank:

     5. Termination. This option shall terminate if and when the Option Holder
shall cease to be an employee of the Corporation or a Subsidiary, except as
follows:

          (a) Death. If the Option Holder dies while employed by the Corporation
     or a Subsidiary, or while this option was exercisable by him in accordance
     with paragraph (b) or (c) below after his retirement, permanent disability
     or the termination of his employment other than for cause, this option may
     be exercised (for not more than the number of shares as to which the Option
     Holder might have exercised this Option at the time of such death) by the
     personal representative of the decedent or, by such person or persons as
     shall have acquired the Option Holder's rights under this option by will or
     by the laws of descent and distribution at any time (i) prior to the
     Expiration Date, in the event the Expiration Date is not more than one year
     following the date of death, or (ii) within such one year, in the event
     that the Expiration Date is more than one year following such date of
     death;

          (b) Retirement or Permanent Disability. If the Option Holder retires
     or becomes permanently disabled, this option may be exercised (for not more
     than the number of shares as to which the Option Holder might have
     exercised this option on the date of his retirement or permanent
     disability) at any time prior to the Expiration Date. As used herein,
     "retirement" shall mean the date on which the Option Holder voluntarily
     terminates his employment with the Corporation or a Subsidiary with the
     permanent intention of not seeking other employment or becoming
     self-employed except for part-time consulting; and "permanent disability"
     shall mean the date on which the Option Holder has not worked or been able
     to work due to physical or mental incapacity for a period of 180

          (c) Other Termination. If the employment of the Option Holder with the
     Corporation or a Subsidiary is terminated for any reason other than by
     death, permanent disability or retirement, this option may be exercised
     (for not more than the number of shares as to which the Option Holder might
     have exercised this option on the date on which his employment was
     terminated) at any time (i) prior to the Expiration Date in the event the
     Expiration Date is not more than three months following the date of such
     retirement or termination, or (ii) within such three-month period, in the
     event that the Expiration Date is more than three months following the date
     of such termination of employment; provided, however, that if the Option
     Holder is dismissed for cause, of which the Committee shall be the sole
     judge, this option shall terminate forthwith.

                                       3

The Committee may determine that, for the purpose of the Plan, the Option Holder
while on a leave of absence will be considered as still in the employ of the
Corporation, provided that this option shall be exercisable during a leave of
absence only as to the number of shares as to which it was exercisable at the
commencement of such leave of absence.

     6. Method of Exercise. A person electing to exercise this option shall
deliver to the Secretary of the Corporation a written notice of such election
and of the number of shares such person has elected to purchase and shall at the
time of exercise tender the full purchase price of the shares such person has
elected to purchase.

     7.   Adjustments

          (a) If the outstanding shares of Common Stock of the Company are
increased, decreased, changed into or exchanged for a different number or kind
of shares or securities of the Company through recapitalization (other than the
conversion of convertible securities according to their terms),
reclassification, stock dividend, stock split or reverse stock split, an
appropriate and proportionate adjustment shall be made, or if the Company shall
spin-off, spin-out or otherwise distribute assets with respect to the
out-standing shares of Common Stock of the Company, an appropriate and
proportionate adjustment may be made in the discretion of the Committee, in (i)
the maximum number and kind of shares as to which options may be granted under
the Plan, (ii) the number and kind of shares subject to outstanding options, and
(iii) the exercise price for each share under outstanding options, without any
change in the aggregate purchase price or value applicable to the unexercised
portion of the outstanding options.

          (b) In the event of the dissolution or liquidation of the Company, or
upon any merger, consolidation or reorganization of the Company with any other
corporations or entities as a result of which the Company is not the surviving
corporation, or upon the sale of all or substantially all of the assets of the
Company or the acquisition of more than 80% of the stock of the Company by
another corporation or entity, there shall be substituted for each of the shares
of Common Stock then subject to the Plan the number and kind of shares of stock,
securities or other assets which would have been issuable or payable in respect
of or in exchange for such Common Stock then subject to the Plan, as if the
optionee had been the owner of such shares as of the transaction date. Any
securities so substituted shall be subject to similar successive adjustments.

     8. No Right to Continued Employment. Nothing in the Plan, in this stock
option agreement or in any other instrument executed pursuant thereto shall
confer upon the Option Holder any right to continue in the employ of the
Corporation or any Subsidiary of the Corporation or shall interfere in any way
with the right of the Corporation or any such Subsidiary to at any time
terminate the employment of the Option Holder with or without cause.

Corporation, all applicable requirements of federal and state law and of the
Securities and Exchange Commission pertaining to the issuance and sale of such
shares and any applicable listing requirements of any national securities
exchange on which shares of the same class are then listed, shall have been
fully complied with. In connection with any such issuance or transfer, the
person acquiring the shares shall, if requested by the Corporation, give
assurances satisfactory to counsel to the Corporation in respect of such matters
as the Corporation or any Subsidiary of the Corporation may deem desirable to
assure compliance with all applicable legal requirements.

beneficiary or other person claiming under or through the Option Holder shall
have any right, title or interest in or to any shares of Common Stock allocated
or reserved for the purpose of the Plan or subject to this Agreement except as
to such shares of Common Stock, if any, as shall have been issued or transferred
to such person.

make such provisions as it may deem appropriate for the withholding of any taxes
which the Corporation or such Subsidiary determines it is required to withhold
in connection with this stock option agreement and the transactions contemplated
hereby, and the Corporation or any such Subsidiary may require the Option Holder
or other person exercising this Option to pay to the Corporation or such
Subsidiary in cash any amount or amounts which may be required to be paid as
withheld taxes in connection with any exercise of this Option or any other
transaction contemplated hereby as a condition to the exercise of this Option
and issuance of shares of the Common Stock.

     12. No Assignments. Neither this stock option agreement, not this option
nor any other rights and privileges granted hereby shall be transferred,
assigned, pledged or hypothecated in any way, whether by operation of law of
descent and distribution. Upon any attempt to so transfer, assign, pledge,
hypothecate or otherwise dispose of this stock option agreement, this option or
any other right or privilege granted hereby contrary to the provisions hereof,
this stock option agreement, this option and all of such rights and privileges
shall immediately become null and void.

insurance, profit-sharing or other employee benefit plan or program of the
Corporation or of any Subsidiary of the Corporation.

     14. The Plan. The option hereby granted is subject to, and the Corporation
and Option Holder agree to be bound by all of the terms and conditions of the
Plan as the same may be amended from time to time in accordance with the terms
thereof, but

                                       5
<PAGE>   6

no such amendment may adversely affect the Option Holder's rights
under this stock option agreement. Option Holder acknowledges receipt of a
complete copy of the Plan.

                                 DESCRIPTION OF
                    2000 EXECUTIVE OFFICER BONUS ARRANGEMENT


     The Ducommun Incorporated 2000 Executive Officer Bonus Arrangement (the
"Arrangement") is designed to reward achievement of annual operating plan
objectives in order to build profitability and provide competitive compensation
levels. The Arrangement contains a formula-based incentive plan driven by sales,
net income, cash flow and return on asset performance in excess of established
thresholds. The participants in the Arrangement are the five Ducommun corporate
officers and five subsidiary presidents.

     The Arrangement provides for bonus awards ranging from 0 to 100% of annual
base salary depending on position. The targeted bonus award under the
Arrangement is half of the maximum bonus eligibility for each individual. Bonus
awards are based on a combination of total corporate performance and on
individual performance of executive officers. The subsidiary presidents are also
measured based upon the financial performance of their operating units. All
awards are subject to the approval of the Compensation Committee of the Board of
Directors.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

ACQUISITIONS

In November 1999, the Company, through a wholly-owned subsidiary, acquired the
assets and assumed certain liabilities of Parsons Precision Products, Inc.
("Parsons") for $22,073,000 in cash. Parsons is a leading manufacturer of
complex titanium hot-formed subassemblies and components for commercial and
military aerospace applications. In April 1999, the Company acquired the capital
stock of Sheet Metal Specialties Company ("SMS") for $10,096,000 in cash, net of
cash acquired and payments of other liabilities of SMS, and a $1,500,000 note.
SMS is a manufacturer of subassemblies for commercial and military aerospace
applications. In June 1998, the Company acquired the capital stock of American
Electronics, Inc. ("AEI") for $8,165,000 in cash and $1,900,000 in other
liabilities. AEI is a leading manufacturer of high precision actuators, stepper
motors, fractional horsepower motors and resolvers principally for commercial
and military space applications. The acquisitions of Parsons, SMS and AEI were
accounted for under the purchase method of accounting. These acquisitions
accounted for approximately $30,086,000 and $5,628,000 of the excess of cost
over net assets acquired at December 31, 1999, and December 31, 1998,
respectively, and is being amortized on a straight-line basis over 15 to 20
years. The consolidated statements of income include the operating results for
Parsons, SMS and AEI since the dates of the acquisitions.

    The acquisitions were funded from internally generated cash, notes and other
accounts payable to sellers, and borrowings under the Company's credit agreement
with its bank (see Financial Condition for additional information). These
acquisitions strengthened the Company's position in the aerospace industry and
added complementary lines of business.


DISPOSITIONS

In August 1998, the Company sold the capital stock of its wireless
communications subsidiary, 3dbm, Inc. ("3dbm"). The subsidiary was sold for
$17,250,000 in cash, resulting in a pretax gain of $9,249,000 on the sale and an
after-tax gain of $6,206,000, or $.53 per diluted share, which was recorded in
the third quarter of 1998. The Company sold 3dbm because the level of investment
required to ensure the long-term viability of 3dbm in the wireless systems
infrastructure business was more than the Company was willing to commit.


RESULTS OF OPERATIONS

1999 Compared to 1998 -- Net sales decreased 14% to $146,054,000 in 1999. The
decrease resulted primarily from a reduction in the Company's sales of
commercial and military aftermarket products in its aircraft seating and
electromechanical switch businesses, lower sales for Boeing commercial aircraft,
lower sales for space programs, and lower sales for certain commercial and
military programs due to a lack of titanium availability. The acquisitions of
SMS and Parsons increased sales by approximately $7,624,000 in 1999. The
Company's mix of business was approximately 58% commercial, 31% military and 11%
space in 1999. Foreign sales increased to 19% of sales from 17% in 1998. The
Company did not have sales to any foreign country greater than 4.2% of total
sales in 1999 or 1998.

     The Company had substantial sales to Boeing, Lockheed Martin and Raytheon.
During 1999 and 1998, sales to Boeing were $40,310,000 and $48,334,000,
respectively; sales to Lockheed Martin were $15,470,000 and $18,465,000,
respectively; and sales to Raytheon were $10,138,000 and $12,596,000,
respectively. At December 31, 1999, trade receivables from Boeing, Lockheed
Martin and Raytheon were $3,940,000, $1,906,000 and $1,819,000, respectively.
The sales and receivables relating to Boeing, Lockheed Martin and Raytheon are
diversified over a number of different commercial, space and military programs.

     The Company's commercial business is represented on virtually all of
today's major commercial aircraft. During 1999, sales for Boeing aircraft were
lower, principally because of lower commercial aircraft production rates and
what the Company believes are ongoing inventory reductions by Boeing and its
major suppliers. Sales related to commercial business were approximately
$84,943,000, or 58% of total sales in 1999.

     Military components manufactured by the Company are employed in many of the
country's front-line fighters, bombers, helicopters and support aircraft, as
well as many land and sea-based vehicles. The Company's defense business is
widely diversified among military manufacturers and programs. Sales related to
military programs were approximately $44,919,000, or 31% of total sales in 1999.
The C-17 program accounted for approximately $8,270,000 in sales in 1999.

     In the space sector, the Company produces components for the expendable
fuel tanks which help boost the Space Shuttle vehicle into orbit. Components are
also produced for a variety of unmanned launch vehicles and satellite programs.
Sales related to space programs were approximately $16,192,000, or 11% of total
sales in 1999.

     At December 31, 1999, backlog believed to be firm was approximately
$213,100,000, compared to $138,200,000 at December 31, 1998. The backlog
increase from December 31, 1998 was due primarily to the award of follow-on
contracts by Lockheed Martin for the Space Shuttle program. These contracts,
valued in excess of $93,000,000 extend

the Company's scope of work through 2006. The Company also experienced backlog
growth at December 31, 1999 of approximately $29,000,000 from the acquisitions
of SMS and Parsons in 1999. Approximately $95,000,000 of the total backlog is
expected to be delivered during 2000.

     Gross profit, as a percentage of sales, decreased to 31.7% in 1999 from
33.3% in 1998. This decrease was primarily the result of changes in sales mix,
pricing pressures from customers and nonvariable production costs spread over
lower sales.

     Selling, general and administrative expenses, as a percentage of sales,
were 14.9% in 1999, compared to 15.0% in 1998.

     Goodwill amortization expense, as a percentage of sales, was 1.4% in 1999,
compared to 0.8% in 1998. This increase was primarily the result of higher
goodwill amortization expense related to the SMS and Parsons acquisitions in
1999.

     Interest expense increased 388% to $610,000 in 1999 primarily due to higher
debt levels in 1999 compared to 1998.

     Income tax expense decreased to $8,448,000 in 1999, compared to $15,226,000
in 1998. The decrease in income tax expense was primarily due to the decrease in
income before taxes and a decrease of $3,043,000 of income taxes related to the
gain on the sale of 3dbm in 1998. Cash expended to pay income taxes decreased to
$8,170,000 in 1999, compared to $9,464,000 in 1998, primarily as a result of
taxes paid in 1998 on the gain on the sale of 3dbm.

     Net income for 1999 was $13,444,000, or $1.28 diluted earnings per share,
compared to $23,693,000, or $2.04 diluted earnings per share, in 1998. Net
income for 1998 included an after-tax gain of $6,206,000, or $0.53 per diluted
share, on the sale of the capital stock of 3dbm.

1998 COMPARED TO 1997 -- Net sales increased 9% to $170,772,000 in 1998. The
increase resulted primarily from a broad-based increase in sales in most of the
Company's product lines due to outsourcing from prime contractors and first tier
subcontractors as well as new contract awards, partially offset by lower
commercial and military aftermarket sales. The net effect on sales of the
acquisition of AEI and the divestiture of 3dbm in 1998 compared to 1997 was a
decrease in sales of approximately $111,000 in 1998. The Company's mix of
business was approximately 60% commercial, 29% military and 11% space in 1998.
Foreign sales decreased to 17% of sales from 19% in 1997. Canada was the only
foreign country in which the Company had sales of 3.5% or more of total sales,
with sales of $6,173,000 in 1998 and $7,950,000 in 1997.

     The Company had substantial sales to Boeing, Lockheed Martin and Raytheon.
During 1998 and 1997, sales to Boeing were $48,334,000 and $36,375,000,
respectively; sales to Lockheed Martin were $18,465,000 and $17,455,000,
respectively; and sales to Raytheon were $12,596,000 and $9,101,000,
respectively. At December 31, 1998, trade receivables from Boeing, Lockheed
Martin and Raytheon were $4,352,000, $1,891,000 and $1,752,000, respectively.
The sales and receivables relating to Boeing, Lockheed Martin and Raytheon are
diversified over a number of different commercial, space and military programs.

     During 1998, commercial sales increased primarily as a result of increased
commercial aircraft build rates and new contract awards. Sales related to
commercial business were approximately $102,432,000, or 60% of total sales in
1998. Sales related to military programs were approximately $50,231,000, or 29%
of total sales in 1998. The C-17 program accounted for approximately $9,846,000
in sales in 1998. Sales related to space programs were approximately
$18,109,000, or 11% of total sales in 1998.

     At December 31, 1998, backlog believed to be firm was approximately
$138,200,000, compared to $155,700,000 at December 31, 1997. The backlog
decrease from December 31, 1997 was due to product shipments in 1998 at a faster
rate than new business was awarded to replace it. However, the Company
experienced backlog growth principally in the Boeing 737, 777 and C-17 aircraft.

     Gross profit, as a percentage of sales, increased to 33.3% in 1998 from
32.0% in 1997. This increase was primarily the result of changes in sales mix
and lower production costs.

     Selling, general and administrative expenses, as a percentage of sales,
were 15.8% in 1998, compared to 15.9% in 1997.

     Interest expense decreased 80% to $125,000 in 1998 primarily due to higher
interest income from invested cash in 1998 compared to 1997, which was offset
against interest expense.

     Income tax expense increased to $15,226,000 in 1998, compared to
$10,356,000 in 1997. The increase in income tax expense was primarily due to
$3,043,000 of income taxes related to the gain on the sale of 3dbm and the
increase in income before taxes. Cash expended to pay income taxes increased to
$9,464,000 in 1998, compared to $4,932,000 in 1997, primarily as a result of
taxes paid on the gain on the sale of 3dbm.

     Net income for 1998 was $23,693,000, or $2.04 diluted earnings per share,
compared to $14,297,000, or $1.20 diluted earnings per share, in 1997. Net
income for 1998 included an after-tax gain of $6,206,000, or $0.53 per diluted
share, on the sale of the capital stock of 3dbm.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

FINANCIAL CONDITION

Liquidity and Capital Resources -- Cash flow from operating activities for 1999
was $18,462,000, compared to $25,172,000 in 1998. The decrease in cash flow from
operating activities resulted principally from a decrease in net income, an
increase in inventories and a decrease in accrued liabilities partially offset
by a reduction in trade receivables. During 1999, the Company spent $32,169,000
to purchase SMS and Parsons, $9,414,000 to repurchase shares of the Company's
common stock, $5,778,000 on capital expenditures and had net borrowings of
$19,556,000.

     In November 1999, the Company, through a wholly-owned subsidiary, acquired
the assets and assumed certain liabilities of Parsons for $22,073,000 in cash.
Parsons is a leading manufacturer of complex titanium hot-formed subassemblies
and components for commercial and military aerospace applications. In April
1999, the Company acquired the capital stock of SMS for $10,096,000 in cash, net
of cash acquired and payments of other liabilities of SMS, and a $1,500,000
note. SMS is a manufacturer of subassemblies for commercial and military
aerospace applications. In June 1998, the Company acquired the capital stock of
AEI for $8,165,000 in cash and $1,900,000 in other liabilities. AEI is a leading
manufacturer of high precision actuators, stepper motors, fractional horsepower
motors and resolvers principally for commercial and military space applications.
The acquisitions were funded from internally generated cash, notes and other
accounts payable to sellers and borrowings under the Company's credit agreement
with its bank. These acquisitions strengthened the Company's position in the
aerospace industry and added complementary lines of business.

     In August 1998, the Company sold the capital stock of its wireless
communications subsidiary, 3dbm, Inc. The subsidiary was sold for $17,250,000 in
cash, resulting in a pretax gain of $9,249,000 on the sale and an after-tax gain
of $6,206,000, or $.53 per diluted share, which was recorded in the third
quarter of 1998. The Company sold 3dbm, Inc. because the level of investment
required to ensure the long-term viability of 3dbm, Inc. in the wireless systems
infrastructure business was more than the Company was willing to commit.

     The Company's bank credit agreement provides for a $40,000,000 unsecured
revolving credit line with an expiration date of July 1, 2002. At December 31,
1999, the Company had $19,010,000 of unused lines of credit, after deducting
$20,990,000 of loans outstanding.

     The Company continues to depend on operating cash flow and the availability
of its bank line of credit to provide short-term liquidity. Cash from operations
and bank borrowing capacity are expected to provide sufficient liquidity to meet
the Company's obligations during 2000.

     Aggregate maturities of long-term debt during the next five years are as
follows: 2000, $1,496,000; 2001, $1,409,000; 2002, $22,365,000; 2003, $560,000;
2004, $2,010,000.

     The Company expects to spend less than $16,000,000 for capital expenditures
in 2000. The Company believes that the ongoing subcontractor consolidation makes
acquisition an increasingly important component of the Company's future growth,
accordingly, the Company plans to continue to seek attractive acquisition
opportunities and to make substantial capital expenditures for manufacturing
equipment and facilities to support long-term aerospace structure contracts for
both commercial and military aircraft and space programs. These expenditures are
expected to place the Company in a favorable competitive position among
aerospace subcontractors and to allow the Company to take advantage of the
off-load requirements from its customers.

     Since 1998, the Company's Board of Directors has authorized the repurchase
of up to $30,000,000 of its common stock. The Company repurchased in the open
market 931,762 shares of its common stock in 1998 for a total of $14,652,000 and
877,300 shares of its common stock in 1999 for a total of $9,414,000. In April
1999, the Company cancelled 953,762 shares of treasury stock.

     Ducommun's subsidiary, Aerochem, Inc. ("Aerochem"), is a major supplier of
chemical milling services for the aerospace industry. Aerochem has been directed
by California environmental agencies to investigate and take corrective action
for groundwater contamination at its El Mirage, California facility (the
"Site"). Aerochem expects to spend approximately $1 million for future
investigation and corrective action at the Site, and the Company has established
a provision for such costs. However, the Company's ultimate liability in
connection with the Site will depend upon a number of factors, including changes
in existing laws and regulations, and the design and cost of the construction,
operation and maintenance of the corrective action.

     Com Dev Consulting Ltd. ("Com Dev") has filed a complaint against the
Company and certain of its officers relating to the sale of the capital stock of
3dbm by the Company to Com Dev in August 1998. On February 3, 2000, the United
States District Court dismissed the complaint without prejudice. The Company
intends to vigorously defend the matter if


                                       15
<PAGE>   6

                                                           Ducommun Incorporated

Com Dev attempts to reassert its claims. While it is not feasible to predict the
outcome of this matter, the Company presently believes that the final resolution
of the matter will not have a material adverse effect on its consolidated
financial position or results of operations.

     In the normal course of business, Ducommun and its subsidiaries are
defendants in certain other litigation, claims and inquiries, including matters
relating to environmental laws. In addition, the Company makes various
commitments and incurs contingent liabilities. While it is not feasible to
predict the outcome of these matters, the Company does not presently expect that
any sum it may be required to pay in connection with these matters would have a
material adverse effect on its consolidated financial position or results of
operations.


FUTURE ACCOUNTING REQUIREMENTS

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities" ("SFAS 133"). SFAS 133 will become effective for the
Company in 2001. The adoption of SFAS 133 is not expected to have a material
effect on the Company's financial position, results of operations or cash flow.

YEAR 2000

The Company has substantially completed its systems Year 2000 date conversion
project to address necessary code changes, testing, and implementation. Critical
systems were inventoried, assessed and tested for Year 2000 compliance, and the
Company has developed contingency plans to the extent feasible. The cost of this
project was approximately $224,000. The Company continues to evaluate both its
products and its machinery and equipment against Year 2000 concerns. As a result
of these ongoing evaluations, the Company is not currently aware of any
significant exposure to contingencies related to the Year 2000 issue as a result
of its information systems software, products, or machinery and equipment. All
planned evaluation and testing of material internal software applications,
operating systems, products and machinery and equipment has been completed with
no material effect on the Company's operations and without any material
expenditures or other material diversions of resources. The Company continues to
work with third parties with which it has a material relationship to attempt to
determine their preparedness with respect to Year 2000 issues and to analyze the
risk to the Company in the event any such third parties experience significant
business interruptions as a result of Year 2000 noncompliance. However, there
can be no assurance that the systems of other companies on which the Company's
business or systems rely are Year 2000 compliant or that any failure to be Year
2000 compliant by another company would not have an adverse effect on the
Company's business or systems. To date the Company has not experienced any
significant Year 2000 problems.


FORWARD LOOKING STATEMENT AND RISK FACTORS

Any forward-looking statements made in this Annual Report involve risks and
uncertainties. The Company's future financial results could differ materially
from those anticipated due to the Company's dependence on conditions in the
airline industry, the level of new commercial aircraft orders, the production
rate for the Space Shuttle and other space programs, the level of defense
spending, competitive pricing pressures, technology and product development
risks and uncertainties, product performance, risks associated with acquisitions
and dispositions of businesses by the Company, increasing consolidation of
customers and suppliers in the aerospace industry, availability of raw materials
and components from suppliers, and other factors beyond the Company's control.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Consolidation: The consolidated financial statements include the accounts of the
Company and its subsidiaries, after eliminating significant intercompany
balances and transactions.

Cash Equivalents: Cash equivalents consist of highly liquid instruments
purchased with original maturities of three months or less.

Revenue Recognition: Revenue, including sales under fixed price contracts, is
recognized upon shipment of products or when title passes based on the terms of
sale. The effects of revisions in contract value or estimated costs of
completion are recognized over the remaining terms of the agreement. Provisions
for estimated losses on contracts are recorded in the period identified.

Inventory Valuation: Inventories are stated at the lower of cost or market. Cost
is determined based upon the first-in, first-out method. Costs on fixed price
contracts in progress included in inventory represent accumulated recoverable
costs less the portion of such costs allocated to delivered units and
applicable progress payments received.

Property and Depreciation: Property and equipment, including assets recorded
under capital leases, are recorded at cost. Depreciation and amortization are
computed using the straight-line method over the estimated useful lives ranging
from 2 to 40 years and, in the case of leasehold improvements, over the shorter
of the lives of the improvements or the lease term.

Income Taxes: Income taxes are accounted for using an asset and liability
approach that requires the recognition of deferred tax assets and liabilities
for the expected future tax consequences of events that have been recognized in
the Company's financial statements or tax returns.

Excess of Costs Over Net Assets Acquired: The cost of acquired businesses in
excess of the fair market value of their underlying net assets is amortized on
the straight-line basis over periods ranging from 15 to 40 years. The Company
assesses the recoverability of cost in excess of net assets of acquired
businesses by determining whether the amortization of this intangible asset over
its remaining life can be recovered through future operating cash flows.

Environmental Liabilities: Environmental liabilities are recorded when
environmental assessments and/or remedial efforts are probable and costs can be
reasonably estimated. Generally, the timing of these accruals coincides with the
completion of a feasibility study or the Company's commitment to a formal plan
of action.

Earnings Per Share: Basic earnings per share is computed by dividing income
available to common shareholders by the weighted average number of common shares
outstanding in each year. Diluted earnings per share is computed by dividing
income available to common shareholders plus income associated with dilutive
securities by the weighted average number of common shares outstanding plus any
potential dilution that could occur if securities or other contracts to issue
common stock were exercised or converted into common stock in each year. In
1999, 1998 and 1997, income available to common shareholders was $13,444,000,
$23,693,000 and $14,297,000, respectively. In 1999, 1998 and 1997, the weighted
average number of common shares outstanding was 10,209,000, 11,149,000 and
11,037,000, respectively, and the dilutive shares associated with stock options
were 309,000, 469,000 and 829,000, respectively.

Stock-Based Compensation: Compensation cost attributable to stock option and
similar plans is recognized based on the difference, if any, between the
closing market price of the stock on the date of grant over the exercise price
of the option. The Company has not issued any stock options with an exercise
price less than the closing market price of the stock on the date of grant.

Comprehensive Income: In June 1997, the Financial Accounting Standards Board
issued Statement of Financial Accounting Standards No. 130, "Reporting
Comprehensive Income" ("SFAS 130"). SFAS 130 was effective for the Company
during 1998. This statement divides comprehensive income into net income and
other comprehensive income. The Company has no items of other comprehensive
income in any period presented and is consequently not required to report
comprehensive income.

Use of Estimates: Certain amounts and disclosures included in the consolidated
financial statements required management to make estimates that could differ
from actual results.


NOTE 2. ACQUISITIONS AND DISPOSITION

In November 1999, the Company, through a wholly-owned subsidiary, acquired the
assets and assumed certain liabilities of Parsons Precision Products, Inc.
("Parsons") for $22,073,000 in cash. Parsons is a leading manufacturer of
complex titanium hot-formed subassemblies and components for commercial and
military aerospace applications. In April 1999, the Company acquired the capital
stock of Sheet Metal Specialties Company ("SMS") for $10,096,000 in cash, net of
cash acquired and payments of other liabilities of SMS, and a $1,500,000 note.
SMS is a manufacturer of subassemblies for commercial and military aerospace
applications. In June 1998, the Company acquired the capital stock of American
Electronics, Inc. ("AEI") for $8,165,000 in cash and $1,900,000 in other
liabilities. AEI is a leading manufacturer of high-precision actuators, stepper
motors, fractional horsepower motors and resolvers principally for commercial
and military space applications.

     The acquisitions of Parsons, SMS and AEI were accounted for under the
purchase method of accounting and, accordingly, the operating results for
Parsons, SMS and AEI have been included in the consolidated statements of income
since the dates of the respective acquisitions. The cost of the acquisitions was
allocated on the basis of the estimated fair value of assets acquired and
liabilities assumed. These acquisitions accounted for approximately $30,086,000
and $5,628,000 of the excess of cost over net assets acquired at December 31,
1999, and December 31, 1998, respectively, and is being amortized on a
straight-line basis over 15 to 20 years.

     The following table presents unaudited pro forma consolidated operating
results for the Company for the years ended December 31, 1999 and December 31,
1998, as if the SMS and Parsons acquisitions had occurred as of the beginning of
the periods presented.

</TABLE>

     The unaudited pro forma consolidated operating results of the Company are
not necessarily indicative of the operating results that would have been
achieved had the SMS and Parsons acquisitions been consummated at the beginning
of the periods presented, and should not be construed as representative of
future operating results.

     In August 1998, the Company sold the capital stock of its wireless
communications subsidiary, 3dbm, Inc. The subsidiary was sold for $17,250,000 in
cash, resulting in a pretax gain of $9,249,000 on the sale and an after-tax gain

</TABLE>

     The Company's bank credit agreement provides for a $40,000,000 unsecured
revolving credit line with an expiration date of July 1, 2002. Interest is
payable monthly on the outstanding borrowings based on the bank's prime rate
(8.50% at December 31, 1999) minus 0.25%. A Eurodollar pricing option is also
available to the Company for terms of up to six months at the Eurodollar rate
plus a spread based on the leverage ratio of the Company calculated at the end
of each fiscal quarter (1.00% at December 31, 1999). At December 31, 1999, the
Company had $19,010,000 of unused lines of credit, after deducting $20,990,000
of loans outstanding. The credit agreement includes fixed charge coverage and
maximum leverage ratios, an unused commitment fee of .125%, and limitations on
future dividend payments and outside indebtedness.

     The weighted average interest rate on borrowings outstanding was 7.09% and
6.73% at December 31, 1999 and 1998, respectively.

     The carrying amount of long-term debt approximates fair value based on the
terms of the related debt, recent transactions and estimates using interest
rates currently available to the Company for debt with similar terms and
remaining maturities.

     Aggregate maturities of long-term debt during the next five years are as
follows: 2000, $1,496,000; 2001, $1,409,000; 2002, $22,365,000; 2003, $560,000;
2004, $2,010,000.


NOTE 7. SHAREHOLDERS' EQUITY

At December 31, 1999 and 1998, no preferred shares were issued or outstanding.

     Since 1998, the Company's Board of Directors has authorized the repurchase
of up to $30,000,000 of its common stock. The Company repurchased in the open
market 931,762 shares of its common stock in 1998 for a total of $14,652,000 and
877,300 shares of its common stock in 1999 for a total of $9,414,000. In April
1999, the Company cancelled 953,762 shares of treasury stock.


NOTE 8. STOCK OPTIONS

The Company has three stock option or incentive plans. Stock awards may be made
to directors, officers and key employees under the stock plans on terms
determined by the Compensation Committee of the Board of Directors or, with
respect to directors, on terms determined by the Board of Directors. Stock
options have been and may be granted to directors, officers and key employees
under the stock plans at prices not less than 100% of the market value on the
date of grant and expire not more than ten years from the date of grant. The
option price and number of shares are subject to adjustment under certain
dilutive circumstances. At December 31, 1999, options for 612,866 shares of
common stock were exercisable.

     The Company has adopted Statement of Financial Accounting Standards No.
123, "Accounting for Stock-Based Compensation" ("SFAS 123"). In accordance with
the provisions of SFAS 123, the Company applies APB Opinion No. 25, "Accounting
for Stock Issued to Employees," and related interpretations in accounting for
its plans and does not recognize compensation expense for its stock-based
compensation plans based on the fair value method prescribed by SFAS 123. If the
Company had elected to recognize compensation expense based upon the fair value
at the grant date for awards under these plans consistent with the methodology
prescribed by SFAS 123, the Company's net income and earnings per share would be
reduced to the pro forma amounts indicated below:

     These pro forma amounts may not be representative of future disclosures
since the estimated fair value of stock options is amortized to expense over the
vesting period, and additional options may be granted in future years. The fair
value for these options was estimated at the date of grant using the
Black-Scholes option pricing model with the following weighted-average
assumptions for 1999, 1998 and 1997, respectively: dividend yields of zero
percent; expected monthly volatility of 36.15, 29.17 and 30.62 percent;
risk-free interest rates of 4.88, 5.53 and 6.38 percent; and expected option
life of four years for 1999, 1998 and 1997. The weighted average fair value of
options granted during 1999, 1998 and 1997, for which the exercise price equals
the market price on the grant date, was $4.45, $10.02 and $4.99, respectively.

     At December 31, 1999, 547,364 common shares were available for future
grants and 1,003,912 common shares were reserved for the exercise of outstanding
options. Option activity during the three years ended December 31, 1999 was as
follows:

NOTE 9. EMPLOYEE BENEFIT PLANS

The Company has an unfunded supplemental retirement plan that was suspended in
1986, but which continues to cover certain former executives. The accumulated
benefit obligations under the plan at December 31, 1999 and December 31, 1998
were $567,000 and $638,000, respectively, which are included in accrued
liabilities.

     The Company provides certain health care benefits for retired employees.
Employees become eligible for these benefits if they meet minimum age and
service requirements, are eligible for retirement benefits and agree to
contribute a portion of the cost. As of December 31, 1999, there were 132
current and retired employees and dependents eligible for such benefits.
Eligibility for additional employees to become covered by retiree health
benefits was terminated in 1988. The Company accrues postretirement health care
benefits over the period in which active employees become eligible for such
benefits. The accrued postretirement benefit cost under these plans is included
in accrued liabilities.

     The components of net periodic postretirement benefits cost for these plans
are as follows:

</TABLE>

     The accumulated postretirement benefit obligations at December 31, 1999 and
1998 were determined using an assumed discount rate of 7.75% and 6.75%,
respectively. For measurement purposes, an 8.0% annual rate of increase in the
per capita cost of covered health care benefits was assumed for 2000; the rate
was assumed to decrease gradually to 4.75% in the year 2009 and remain at that
level thereafter over the projected payout period of the benefits.

     A 1% increase in the assumed annual health care cost trend rate would
increase the present value of the accumulated postretirement benefit obligation
at December 31, 1999, by $300, and the aggregate of the service and interest
cost components of net periodic postretirement benefit cost for the year then
ended by $0.


NOTE 10. LEASES

The Company leases certain facilities and equipment for periods ranging from 1
to 6 years. The leases generally are renewable and provide for the payment of
property taxes, insurance and other costs relative to the property. Rental
expense in 1999, 1998 and 1997 was $3,487,000, $3,483,000 and $4,156,000,
respectively. Future minimum rental payments under operating leases having
initial or remaining noncancelable terms in excess of 1 year at December 31,
1999 are as follows:

NOTE 12. CONTINGENCIES

Ducommun's subsidiary, Aerochem, Inc. ("Aerochem"), is a major supplier of
chemical milling services for the aerospace industry. Aerochem has been directed
by California environmental agencies to investigate and take corrective action
for groundwater contamination at its El Mirage, California facility (the
"Site"). Aerochem expects to spend approximately $1 million for future
investigation and corrective action at the Site, and the Company has established
a provision for such costs. However, the Company's ultimate liability in
connection with the Site will depend upon a number of factors, including changes
in existing laws and regulations, and the design and cost of the construction,
operation and maintenance of the correction action.

     Com Dev Consulting Ltd. ("Com Dev") has filed a complaint against the
Company and certain of its officers relating to the sale of the capital stock of
3dbm by the Company to Com Dev in August 1998. On February 3, 2000, the United
States District Court dismissed the complaint without prejudice. The Company
intends to vigorously defend the matter if Com Dev attempts to reassert its
claims. While it is not feasible to predict the outcome of this matter, the
Company presently believes that the final resolution of the matter will not have
a material adverse effect on its consolidated financial position or results of
operations.

     In the normal course of business, Ducommun and its subsidiaries are
defendants in certain other litigation, claims and inquiries, including matters
relating to environmental laws. In addition, the Company makes various
commitments and incurs contingent liabilities. While it is not feasible to
predict the outcome of these matters, the Company does not presently expect that
any sum it may be required to pay in connection with these matters would have a
material adverse effect on its consolidated financial position or results of
operations.


NOTE 13. MAJOR CUSTOMERS AND CONCENTRATIONS OF CREDIT RISK

The Company provides proprietary products and services to most of the prime
aerospace and aircraft manufacturers. As a result, the Company's sales and trade
receivables are concentrated principally in the aerospace industry.

     The Company had substantial sales to Boeing, Lockheed Martin and Raytheon.
During 1999, 1998 and 1997, sales to Boeing were $40,310,000, $48,334,000 and
$36,375,000, respectively; sales to Lockheed Martin were $15,470,000,
$18,465,000 and $17,455,000, respectively; and sales to Raytheon were
$10,138,000, $12,596,000 and $9,101,000, respectively. At December 31, 1999,
trade receivables from Boeing, Lockheed Martin and Raytheon were $3,940,000,
$1,906,000 and $1,819,000, respectively. The sales and receivables relating to
Boeing, Lockheed Martin and Raytheon are diversified over a number of different
commercial, space and military programs.

     In 1999, 1998 and 1997, foreign sales to manufacturers worldwide were
$28,313,000, $29,007,000 and $29,978,000, respectively. The Company had no sales
to a foreign country greater than 4.2% of total sales in 1999, 1998 and 1997,
respectively. The amounts of revenue, profitability and identifiable assets
attributable to foreign operations are not material when compared with revenue,
profitability and identifiable assets attributed to United States domestic
operations during 1999, 1998 and 1997.

Report of Independent Accountants

To the Board of Directors and Shareholders of Ducommun Incorporated

In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of income, of cash flows and of changes in shareholders'
equity present fairly, in all material respects, the financial position of
Ducommun Incorporated and its subsidiaries at December 31, 1999 and 1998, and
the results of their operations and their cash flows for each of the three years
in the period ended December 31, 1999, in conformity with accounting principles
generally accepted in the United States. 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 auditing standards generally
accepted in the United States which 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, 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.
