                                                                   Exhibit 10(a)

                              EMPLOYMENT AGREEMENT

         THIS EMPLOYMENT AGREEMENT (the "Agreement") is executed this 17 day of
August, 1999, by and between ALLEGHENY TELEDYNE INCORPORATED, a Delaware
corporation with its principal place of business at 10th Floor, Six PPG Place,
Pittsburgh, PA 15222 (with all of its direct and indirect subsidiaries, "ATI" or
the "Employer"), and THOMAS A. CORCORAN, an individual residing in the State of
Maryland (the "Executive").

         In consideration of the premises, mutual covenants and agreements of
the parties contained herein, and other good and valuable consideration, the
receipt and adequacy of which is hereby acknowledged, and intending to be
legally bound, the Employer and the Executive hereby agree as follows:

         1. Employment. The Executive represents and warrants that he is not a
party to any existing agreement or obligation that would prevent him from
entering into an employment relationship with the Employer and performing his
obligations and duties thereunder. The Executive further represents and warrants
that he is not a party to any existing agreement or obligation that would cause
the Employer to be in violation of any third party's rights. Commencing on
September 16, 1999 (the "Effective Date"), the Employer, in reliance on such
representations, shall employ the Executive and the Executive shall accept
employment by the Employer upon the terms and conditions set forth in this
Agreement.

         2. Term. The term of employment (the "Term") shall begin on the
Effective Date and, except as otherwise provided in Sections 6, 7, 8, 9, 10 and
11 below, shall end on July 16, 2004. The Term shall be automatically extended
for one additional month commencing on July 16, 2003 and, if initially extended,
on the last day of each calendar month thereafter (each, an "Extension Date")
unless one party gives written notice to the other on or before an Extension
Date. As of the last day of the month in which a notice not to renew is
delivered, the Term of this Agreement shall be twelve months and shall not be
further extended. The last day of the calendar month in which the Term hereof,
as extended from time to time, is then due to expire is hereinafter referred to
as the "Expiration Date."

         3. Duties. The Executive will serve as President and Chief Executive
Officer ("CEO") of ATI. As President and CEO of ATI, the Executive shall have
the primary responsibility to manage and direct the day-to-day business of ATI,
including the generation of income and control of expenses and principal
responsibility for strategic planning and direction. The Executive shall perform
such duties as are consistent with the role of President and CEO of ATI and such
other duties as may be reasonably assigned to him from time-to-time by ATI's
Board of Directors (the "Board"). With the written consent of the Board, the
Executive may (i) devote a reasonable amount of time and effort to charitable,
industry or community organizations and (ii) subject to the provisions of
Section 6 hereof, the Executive may serve as a director of other companies. As
of the Board meeting next following the Effective Date, the Chairman of the
Board of Directors shall nominate the Executive for a seat on the Board and
shall recommend to the Board that they each and all vote in favor of such
nomination.

   2

         4. Compensation. During the Term, the Executive shall be compensated as
follows:

                  (a) Salary. The Executive shall be paid an annual salary of
not less than $800,000 (the "Annual Base Salary"), to be distributed in equal
periodic installments according to the Employer's customary payroll practices.
The Annual Base Salary will be reviewed annually by the Personnel and
Compensation Committee of the Board (the "Committee") and increased (but not
decreased) if the Committee, in its discretion, determines an increase to be
appropriate, based on the types of factors the Committee usually takes into
account in reviewing executive level salaries, including, but not limited to,
cost-of-living factors, ATI's financial performance, and the Executive's
performance. Nothing contained herein shall be construed to prevent the Employer
from increasing the Executive's Annual Base Salary more often than annually.

                  (b) Bonuses. The bonus arrangements applicable to the
Executive shall be as follows:

                           (i)  Signing Bonus. Promptly following the Effective
         Date, the Executive shall receive a one-time signing bonus of $2
         million in cash.

                           (ii) Special Bonuses. The Executive shall receive (A)
         a special bonus of $600,000 in cash on February 1, 2000, (B) a special
         bonus of $375,000 in cash on January 31, 2001 and a special bonus of
         $375,000 in cash on January 31, 2002. In general, for purposes of the
         foregoing, the Executive must be an employee of ATI on the applicable
         date in order to be entitled to receive the bonus payable on that date;
         provided, however, that Section 10 contains special provisions
         concerning the payment of these bonuses in the event that the
         Executive's employment is terminated by ATI without Cause (as defined
         in Section 9(b)).

                           (iii) AIP Participation. Effective January 1, 2000,
         the Executive shall be eligible to participate in ATI's Annual
         Incentive Plan (the "AIP"). Under the AIP, the Executive's annual bonus
         (the "Performance Bonus") will depend upon the extent to which
         individual and corporate performance goals (the "Goals") are achieved.
         If 100% of the Goals is achieved, the Executive shall earn a
         Performance Bonus equal to 80% of the Annual Base Salary. A sliding
         scale shall determine the Performance Bonus if achievement of the Goals
         is less than or greater than 100%. If 120% of the Goals is achieved,
         the Executive may earn a Performance Bonus of up to 160% of the Annual
         Base Salary. Achievement of 75% of the Goals shall be the minimum
         required to earn a threshold Performance Bonus of 20% of the Annual
         Base Salary. The Board, in its sole discretion, reserves the right to
         modify or eliminate these thresholds.

                  (c) Performance Share Plan. Effective January 1, 2000, the
Executive shall be eligible to participate in ATI's Performance Share Plan (the
"PSP"). Under the PSP, the Executive may earn an award of cash or the common
stock of ATI ("ATI Common Stock" or the "Common Stock of ATI") (denominated at
the grant date) or a combination of both, with an aggregate value up to 150% of
the Annual Base Salary at the grant date. Payment of the award shall be based
upon the extent to which three-year performance goals are achieved by ATI and
shall be made in three installments over a period of three years.

                                       2
   3

                  (d) Retirement Savings Plan. Effective on the earliest date
permitted under the Retirement Savings Plan, the Executive shall participate in
the Retirement Savings Plan. ATI has a tax-qualified defined contribution plan
under which (i) ATI contributes 6.5% of the Executive's base salary, up to
applicable Internal Revenue Service ("IRS") limits and (ii) the Executive may
defer a maximum of 5% to 8% of his compensation (the actual limit depending on
seniority), with ATI matching such deferrals at 50%. All such contributions are
subject to the applicable IRS limits.

                  (e) Supplemental Pension Plan. The Executive shall participate
in ATI's Supplemental Pension Plan in accordance with its terms except to the
extent such terms are modified with respect to the Executive in this subsection.
Under ATI's Supplemental Pension Plan, the Executive's accrued benefit will
equal 50% of his base salary at termination of employment. This benefit will be
payable beginning at age 62 or, if later, upon actual retirement, and will
continue for 120 months or, if less, for a number of months equal to 12 times
the Executive's years of employment with ATI. Notwithstanding any contrary
provision in the Supplemental Pension Plan, (i) if the Executive resigns from
employment with ATI at any time prior to attaining age 58 and does not accept
employment with a third party, ATI shall pay to or with respect to him an amount
equal to 50% of the amount earned from his date of hire to his resignation in
equal monthly installments over the period equal to his period of employment
commencing at the Executive's 62nd birthday and ATI shall pay each such
installment so long as the Executive is not then in the employ of a for-profit
corporation, (ii) if the Executive resigns at any time after attaining age 58,
ATI shall pay him a benefit equal to the benefit he would have accrued if he was
then employed by ATI for the greater of five (5) years or the number of years of
actual employment in equal monthly installments over the period equal to the
applicable of five (5) years or the number of years of actual employment (but
not greater than ten (10) commencing at his age 62 and ATI shall pay each such
installment so long as the Executive is not then in the employ of a for profit
corporation and (iii) the Executive shall forfeit his right to this supplemental
pension if before the Executive attains age 62 his employment is terminated by
the Employer for Cause (as set forth in Section 9 hereof).

                  (f) Stock Acquisition and Retention Plan. The Executive shall
be eligible to elect to participate in the Stock Acquisition and Retention Plan
("SARP") for the 2000 plan year and for each year thereafter during his
employment by ATI in accordance with the terms and conditions of the SARP. Under
the SARP, one share of restricted stock is awarded for each two shares purchased
from ATI or designated by the Executive from previously owned shares (the
Executive may not purchase of designate in any year stock having a value in
excess one year's base salary). The restricted stock will vest if the Executive
remains an employee of ATI and holds the purchased and/or designated stock for
five years after the date of purchase and/or designation.

         5. Expense Reimbursement and Other Benefits.

                  (a) Reimbursement of Expenses. During the Term, the Employer,
upon the submission by the Executive of proper substantiation, including copies
of all relevant invoices, receipts or other evidence reasonably requested by
Employer, shall reimburse the Executive for all reasonable expenses actually
paid or incurred by the Executive in the course of and pursuant

                                       3
   4

to the business of the Employer, including first class or business class air
travel of the Executive and his spouse.

                  (b) Other Employee Benefits. During the Term, the Executive
will be eligible to participate in ATI's employee benefit, fringe benefit and
executive perquisite plans and programs on a basis no less favorable than is
made available to other senior executives of ATI. Such plans and programs shall
include, but not be limited to, ATI's vacation policy (the Executive will be
entitled to no less than 4 weeks' vacation each year), the Non-Qualified
Deferred Compensation Plan (at the Executive's election, some or substantially
all of the Executive's compensation may be deferred), the Supplemental Savings
Plan, the Employee Stock Purchase Plan, ATI's Health, Accident, Disability
Plans, company-paid car, Duquesne Club and one country club membership,

year), coverage under ATI's directors and officers liability insurance,
participation in the annual executive physical program, spousal travel for
company business and the use of a company plane with personal use charged back
to the Executive at cost. The Executive shall also be eligible to participate in
the ATI relocation policy applicable to new executive hires

                  (c) Stock Options. As of the Effective Date, the Executive
shall be granted a non-qualified stock option (the "Option") to purchase 200,000
shares of ATI Common Stock. The exercise price per share of the Option shall
equal the fair market value per share of ATI Common Stock on the Effective Date.
The Option will vest and become exercisable in three equal installments on the
first, second and third anniversaries of the Effective Date. All terms and
conditions of the Option will be governed by ATI's Incentive Plan and a written
stock option agreement containing the terms and conditions customarily used by
ATI in connection with its executive stock option program. The Executive shall
be eligible for additional option grants in future years to the extent such
grants are approved by the Personnel & Compensation Committee of the Board.

                  (d) Restricted Stock. As of the Effective Date, ATI shall
award to the Executive 150,000 shares of ATI Common Stock (the "Restricted
Stock") subject to restrictions which shall provide that the Executive shall not
transfer such shares during the restriction period and shall forfeit such shares
if during the restriction period his employment with ATI terminates for any
reason other than death. The restriction period shall lapse as to all of such
shares on July 16, 2004, or if earlier, on the date of the Executive's death.
The certificates evidencing such restricted shares of Restricted Stock shall be
held in custody by the Secretary of the Employer until the restriction period
with respect thereto shall have lapsed, and the Executive shall deliver to the
Employer a stock power endorsed in blank relating to such shares. The Executive
shall be entitled to receive any dividends payable with respect to such shares
of Restricted Stock beginning on the date of award of such shares. Such stock
award shall be evidenced by a written agreement between ATI and the Executive in
form and substance reasonably satisfactory to the Employer and the Executive,
which agreement shall set forth the terms and conditions of such stock award
consistent with this Agreement.

                  (e) Terms of Participation in Benefit Plans and Programs. The
Executive's participation in ATI's employee and executive benefit plans,
programs and arrangements, as provided in this Agreement, shall be subject in
each case to the applicable terms and conditions

                                       4
   5

of such plans, programs and arrangements. All such plans, programs and
arrangements are subject to amendment or termination by ATI at any time.

         6. Restrictions.

                  (a) Non-competition. During the Term and for a one year period
after the termination of the Term for any reason, the Executive shall not,
directly or indirectly, engage in or have any interest in any sole
proprietorship, partnership, corporation or business or any other person or
entity (whether as an executive, officer, director, partner, agent, security
holder, creditor, consultant or otherwise) that directly or indirectly (or
through any affiliated entity) engages in competition with ATI (for this
purpose, any business that engages in the manufacture or distribution of
products similar to those products manufactured or distributed by ATI at the
time of termination of the Agreement shall be deemed to be in competition with
ATI); provided that such provision shall not apply to the Executive's ownership
of Common Stock of ATI or the acquisition by the Executive, solely as an
investment, of securities of any issuer that is registered under Section 12(b)
or 12(g) of the Securities Exchange Act of 1934, as amended (the "Securities
Exchange Act"), and that are listed or admitted for trading on any United States
national securities exchange or that are quoted on the National Association of
Securities Dealers Automated Quotation System, or any similar system or
automated dissemination of quotations of securities prices in common use, so
long as the Executive does not control, acquire a controlling interest in or
become a member of a group which exercises direct or indirect control or, more
than five percent of any class of capital stock of such corporation.

                  (b) Nondisclosure. During the Term and at all times after the
termination of the Term for any reason, the Executive shall not at any time
divulge, communicate, use to the detriment of ATI or for the benefit of any
other person or persons, or misuse in any way, any Confidential Information (as
hereinafter defined) pertaining to the business of ATI. Any Confidential
Information or data now or hereafter acquired by the Executive with respect to
the business of ATI (which shall include, but not be limited to, information
concerning ATI's financial condition, prospects, technology, customers,
suppliers, sources of leads and methods of doing business) shall be deemed a
valuable, special and unique asset of ATI that is received by the Executive in
confidence and as a fiduciary, and Executive shall remain a fiduciary to ATI
with respect to all of such information. For purposes of this Agreement,
"Confidential Information" means information disclosed to the Executive or known
by the Executive as a consequence of or through his employment by ATI (including
information conceived, originated, discovered or developed by the Executive)
prior to or after the date hereof, and not generally known, about ATI or its
respective businesses. Notwithstanding the foregoing, nothing herein shall be
deemed to restrict the Executive from disclosing Confidential Information to the
extent required by law. None of the foregoing obligations and restrictions apply
to any Confidential Information that the Executive demonstrates was or became
generally available to the public other than as a result of disclosure by the
Executive.

                  (c) Nonsolicitation of Employees and Clients. During the Term
and for a one year period after the termination of the Term for any reason, the
Executive shall not, directly or indirectly, for himself or for any other
person, firm, corporation, partnership, association or other entity, other than
in connection with the performance of Executive's duties under this Agreement,
(i) employ or attempt to employ or enter into any contractual arrangement with
any employee or

                                       5
   6

former employee of the Employer, unless such employee or former employee has not
been employed by the Employer for a period in excess of six months, (ii) call on
or solicit any of the actual or targeted prospective clients of the Employer on
behalf of any person or entity in connection with any business competitive with
the business of the Employer, and/or (iii) make known the names and addresses of
such clients or any information relating in any manner to the Employer's trade
or business relationships with such customers (unless the Executive can
demonstrate that such information was or became generally available to the
public other than as a result of a disclosure by the Executive).

                  (d) Ownership of Developments. All copyrights, patents, trade
secrets, or other intellectual property rights associated with any ideas,
concepts, techniques, inventions, processes, or works of authorship developed or
created by the Executive during the course of performing work for the Employer
or its customers (collectively, the "Work Product") shall belong exclusively to
the Employer and shall, to the extent possible, be considered a work made by the
Executive for hire for the Employer within the meaning of Title 17 of the United
States Code. To the extent the Work Product may not be considered work made by
the Executive for hire for the Employer, the Executive agrees to assign, and
automatically assign at the time of creation of the Work Product, without any
requirement of further consideration, any right, title, or interest the
Executive may have in such Work Product. Upon the request of the Employer, the
Executive shall take such further actions, including execution and delivery of
instruments of conveyance, as may be appropriate to give full and proper effect
to such assignment.

                  (e) Books and Records. All books, records, and accounts
relating in any manner to the customers of the Employer, whether prepared by the
Executive or otherwise coming into the Executive's possession, shall be the
exclusive property of the Employer and shall be returned immediately to the
Employer on termination of the Executive's employment hereunder or on the
Employer's request at any time.

                  (f) Definition of ATI. Solely for purposes of this Section 6,
the terms "ATI" and the "Employer" shall include all current direct and indirect
subsidiaries of ATI, any future subsidiaries of ATI that are operating during
the time periods described herein and any other entities that directly or
indirectly, through one or more intermediaries, control, are controlled by or
are under common control with ATI during the periods described herein.

                  (g) Acknowledgment by Executive. The Executive acknowledges
and confirms that (i) the restrictive covenants contained in this Section 6 are
reasonably necessary to protect the legitimate business interest of the Employer
including the legitimate interests of ATI, and (ii) the restrictions contained
in this Section 6 (including without limitation the length of the term of the
provisions of this Section 6) are not overbroad, over long, or unfair and are
not the result of overreaching, duress or coercion of any kind. The Executive
further acknowledges and confirms that his full, uninhibited and faithful
observance of each of the covenants contained in this Section 6 will not cause
him any undue hardship, financial, or otherwise, and that enforcement of each of
the covenants contained herein will not impair his ability to obtain employment
commensurate with his abilities and on terms fully acceptable to him or
otherwise to obtain income required for the comfortable support of him and his
family and the satisfaction of the needs of his creditors. The Executive
acknowledges and confirms that his special knowledge of the business of ATI is
such as would cause the Employer serious injury or loss if

                                       6
   7

he were to use such ability and knowledge to the benefit of a competitor or were
to compete with ATI in violation of the terms of this Section 6. The Executive
further acknowledges that the restrictions contained in this Section 6 are
intended to be, and shall be, for the benefit of and shall be enforceable by,
the Employer's successors and assigns.

                  (h) Reformation by Court. In the event that a court of
competent jurisdiction shall determine that any provision of this Section 6 is
invalid or more restrictive than permitted under the governing law of such
jurisdiction, then only as to enforcement of this Section 6 within the
jurisdiction of such court, such provision shall be interpreted and enforced as
if it provided for the maximum restriction permitted under such governing law.

                  (i) Extension of Time. If the Executive shall be in violation
of any provision of this Section 6 then each time limitation set forth in this
Section 6 shall be extended for a period of time equal to the period of time
during which such violation or violations occur. If the Employer seeks
injunctive relief from such violation in any court, then the covenants set forth
in this Section 6 shall be extended for a period of time equal to the pendency
of such proceeding including all appeals by the Executive.

                  (j) Survival. The provisions of this Section 6 shall survive
the termination of this Agreement, as applicable.

         7. Death. The Term shall terminate upon the death of the Executive and
be of no further force or effect. Upon such termination, (i) the Employer will
pay the Executive's estate a lump sum equal to the sum of the following
(referred to herein as the "Accrued Obligations"): (A) the Executive's base
salary through the date of termination but not previously paid, (B) the amount
of any bonus, incentive compensation, deferred compensation and other cash
compensation earned by the Executive as of the date of termination under the
terms of the applicable compensation arrangement but not previously paid and (C)
any vacation pay, expense reimbursements and other cash entitlements accrued by
the Executive as of the date of termination but not previously paid, (ii) the
Executive's beneficiary, heirs or estate shall be entitled to receive all
benefits accrued by him as of the date of termination under all qualified and
nonqualified retirement, pension, profit sharing and similar plans and welfare
benefits plans of the Employer to such extent, in such manner and at such time
as are provided under the terms of such plans and arrangements (referred to
herein as the "Accrued Benefits") and (iii) all other obligations of ATI
hereunder shall cease forthwith.

         8. Disability. If during the Term Executive is unable to perform his
services, by reason of illness or incapacity, for a period of 180 consecutive
days or more, the Employer may, at its option, upon written notice to the
Executive, terminate the Term and his employment hereunder. Upon such
termination, the Employer will pay the Accrued Obligations to the Executive in a
lump sum, the Executive shall be entitled to the Accrued Benefits, and all other
obligations of ATI hereunder shall cease forthwith.

         9. Termination for Cause.

                  (a) The Employer shall have the right to terminate the Term
and the Executive's employment hereunder for Cause (as defined below). Upon such
termination, the

                                       7
   8

Employer will pay the Accrued Obligations to the Executive in a lump sum, the
Executive shall be entitled to the Accrued Benefits, and all other obligations
of ATI hereunder shall cease forthwith.

                  (b) For purposes hereof, the term "Cause" shall mean the
Executive's conviction of a felony, personal dishonesty directly affecting ATI,
willful misconduct, breach of a fiduciary duty involving personal profit to the
Executive or intentional failure to perform stated duties provided, however, an
intentional failure to perform stated duties shall not constitute Cause until
the Board provides the Executive with written notice setting forth the specific
duties that, in the Board's view, the Executive has failed to perform and the
Executive is provided a period of thirty (30) days to cure such specific
failure(s) to the satisfaction of the Board.

         10. Termination Without Cause. At any time the Employer shall have the
right to terminate the Term and the Executive's employment hereunder by written
notice to the Executive. Upon any termination pursuant to this Section 10 (that
is not a termination under any of Sections 7, 8, 9 or 11), the Employer shall
pay to the Executive a lump sum equal to the sum of (A) the Annual Base Salary
at the date of termination multiplied by the greater of (i) the number of years
remaining in the Term or (ii) two, (B) the product of the Executive's bonus for
the prior year (not including the bonuses described in Section 4(b)(i) and (ii))
multiplied by the greater of (i) the number of years remaining in the Term or
(ii) two and (C) the amount of any of the special bonuses under Section 4(b)(ii)
that remains unpaid as of the date of termination. The Employer shall also, for
the greater of (i) the remainder of the Term or (ii) two years, continue to pay
its share of the cost of participation by the Executive and his dependents in
health, life and long-term disability benefits that are the same as or
substantially similar to those applicable to the Executive and his dependents at
the date of termination. ATI shall have no further liability hereunder (other
than for reimbursement for reasonable business expenses incurred prior to the
date of termination, subject, however, to the provisions of Section 5(a)). The
Executive shall be entitled to receive all severance payments and benefits
hereunder regardless of any future employment undertaken by the Executive as
long as he is in full compliance with the terms of this Agreement.

         11. Termination by the Executive.

                  (a) The Executive shall at all times have the right, upon 60
days written notice to the Employer, to terminate the Term and his employment
hereunder.

                  (b) Upon any termination pursuant to this Section 11 by the
Executive without Good Reason (as defined below), the Employer will pay the
Accrued Obligations to the Executive in a lump sum, the Executive shall be
entitled to the Accrued Benefits, and all other obligations of ATI hereunder
shall cease forthwith.

                  (c) Upon any termination pursuant to this Section 11 by the
Executive for Good Reason, the Employer shall pay to the Executive the same
amounts that would have been payable by the Employer to the Executive under
Section 10 of this Agreement if the Executive's employment had been terminated
by the Employer without Cause. The Employer shall have no further liability
hereunder (other than for reimbursement for reasonable business expenses
incurred prior to the date of termination, subject, however, to the provisions
of Section 5(a)).

                                       8

The Executive shall be entitled to receive all severance payments and benefits
hereunder regardless of any future employment undertaken by the Executive as
long as he is in full compliance with the terms of this Agreement.

                  (d) For purposes of this Agreement, "Good Reason" shall mean
(i) the assignment to the Executive of any duties inconsistent in any material
respect with the Executive's position (including status, offices, titles and
reporting requirements), authority, duties or responsibilities as contemplated
by Section 3 of this Agreement, or any other action by the Employer which
results in a material diminution in such position, authority, duties or
responsibilities, excluding for this purpose an isolated, insubstantial and
inadvertent action not taken in bad faith and which is remedied by the Employer
promptly after receipt of notice thereof given by the Executive; or (ii) any
failure by the Employer to comply with any of the material provisions of Section
4 or Section 5 of this Agreement, other than an isolated, insubstantial and
inadvertent failure not occurring in bad faith and which is remedied by the
Employer promptly after receipt of notice thereof given by the Executive.

         12. Waivers. It is understood that either party may waive the strict
performance of any covenant or agreement made herein; however, any waiver made
by a party hereto must be duly made in writing in order to be considered a
waiver, and the waiver of one covenant or agreement shall not be considered a
