         The following documents filed by the Company with the Securities and
Exchange Commission (File No. 1-13782) are incorporated in this Registration
Statement by reference and made a part of this Registration Statement:

                  (a) The Company's latest annual report on Form 10-K filed
         pursuant to Section 13(a) of the Securities Exchange Act of 1934, as
         amended (the "1934 Act");

                  (b) All other reports filed by the Company pursuant to
         Section 13(a) of the 1934 Act since the end of the fiscal year covered

                  (c) the description of the Company's Common Stock set forth
         in the Company's Form 8-A filed May 19, 1995 and any description of

         filed by the Company pursuant to the 1934 Act, including any amendment
         or report filed for the purpose of updating such descriptions.

         All documents filed by the Company pursuant to Sections 13(a), 13(c),
14 or 15(d) of the 1934 Act on or subsequent to the date of this Registration
Statement and prior to the filing of a post-effective amendment which indicates

of filing of such documents.

         Any statement contained in a document incorporated or deemed to be
incorporated by reference in this Registration Statement shall be deemed to be

other contemporaneously or subsequently filed document which also is or is

ITEM 4.  DESCRIPTION OF SECURITIES.

         Not applicable.


ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

         Not applicable.


ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     1. Section 145 of the Delaware General Corporation Law ("DGCL"). Section
145 of the DGCL provides that a corporation may indemnify any person who was or
is a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative
or investigative (other than an action by or in the right of the corporation)
by reason of the fact that he is or was a director, officer, employee or agent
of the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise,


   2

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 or conviction, or
upon a plea of nolo contendere or its equivalent, shall not, of itself, create
a presumption that the person did not act in good faith and in a manner which
he reasonably believed to be in or not opposed to the best interests of the
corporation, and with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was unlawful.

         Section 145 also provides that a corporation may indemnify any person
who was or is a party or is threatened to be made a party to any threatened,
pending or completed action or suit by or in the right of the corporation to
procure a judgment in its favor by reason of the fact that he is or was a
director, officer, employee or agent of the corporation, or is or was serving
at the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees) actually and reasonably incurred
by him in connection with the defense or settlement of such action or suit, if
he acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the corporation, and except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the Court of Chancery or the court in which
such action or suit was brought shall determine upon application that, despite
the adjudication of liability, but in view of all the circumstances of the
case, such person is fairly and reasonably entitled to indemnity for such
expenses which the Court of Chancery or such other court shall deem proper.

         To the extent that a director, officer, employee or agent of the
corporation has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to above, or in defense of any claim, issue
or matter therein, such person shall be indemnified against expenses (including
attorneys' fees) actually and reasonably incurred by such person in connection
therewith.

         Any such indemnification (unless ordered by a court) shall be made by
the corporation only as authorized in the specific case upon a determination
that the indemnification of the director, officer, employee or agent is proper
in the circumstances because such person has met the applicable standard of
conduct set forth above. Such determination shall be made:

                  (1) By a majority vote of the directors who were not parties
         to such action, suit or proceeding, even though less than a quorum; or

                  (2) if there are no such directors, or, if such directors so
         direct, by independent legal counsel in a written opinion; or

                  (3) by the stockholders.

         Section 145 permits a Delaware business corporation to purchase and
maintain insurance on behalf of any person who is or was a director, officer,
employee or agent of the corporation, or is or was serving at the request of
the corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, against any
liability asserted against such person and incurred by him in any such capacity
or arising out of his status as such, whether or not the corporation would have
the power to indemnify such person against such liability.

     2. Section 102(b)(7) of the DGCL. Section 102(b)(7) of the DGCL provides
that a corporation may set forth in its Certificate of Incorporation a
provision eliminating or limiting the personal liability of a director to the
corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, provided that such provision shall not eliminate or limit
the liability of a director (i) for any breach of the director's duty of
loyalty to the corporation or its stockholders, (ii) for acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of
law, (iii) under Section 174 of the DGCL regarding the unlawful payment of
dividends or



                                      -2-
   3

approval of unlawful stock repurchases or redemptions, or (iv) for any
transaction from which the director derived an improper personal benefit. No
such provision shall eliminate or limit the liability of a director for any act
or omission occurring prior to the date when such provision becomes effective
(in the case of the Company, October 19, 1989). As noted in paragraph 3 below,
the Company's Amended and Restated Certificate of Incorporation (the "Company
Charter") includes a provision contemplated by Section 102(b)(7) of the DGCL.

     3. Certificate of Incorporation Provision on Liability of Directors. The
Company Charter eliminates the liability of its directors to the fullest extent
permitted by Section 102(b)(7) of the DGCL. The Company Charter provides that
the Company's directors shall not be personally liable to the Company or its
stockholders for monetary damages for breach of their fiduciary duty as
directors, except for liability (i) for any breach of the director's duty of
loyalty to the Company or its stockholders, (ii) for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (iii) pursuant to Section 174 of the DGCL, or (iv) for any transactions
from which a director derived an improper personal benefit. This provision does
not eliminate the duty of care, and in appropriate circumstances equitable
remedies such as injunctive or other forms of nonmonetary relief are available
under Delaware law.

     4. Indemnification Agreements. The Company has entered or intends to enter
into Indemnification Agreements (the "Indemnification Agreements") with its
directors, officers and certain employees, agents, fiduciaries and designees
(each an "Authorized Representative"). The Indemnification Agreements authorize
the Company to pay all or part of certain expenses and liabilities of the
Authorized Representatives, either in advance or otherwise, upon written
request from such Authorized Representatives. The Indemnification Agreements
indemnify the Authorized Representatives in accordance with and to the maximum
extent permitted by the Company Charter and Sections 102(b)(7) and 145 of the
DGCL, all as described in the immediately preceding paragraphs.

     5. Director and Officer Liability Insurance. The Company maintains
director and officer liability insurance covering its directors and officers
with respect to certain liabilities which they may incur in connection with
their serving as such.

ITEM 9.  UNDERTAKINGS.

         (a)      Rule 415 offering.

                  The undersigned registrant hereby undertakes:

                  (1) To file, during any period in which offers or sales are
                  being made, a post-effective amendment to this registration
                  statement:

                  (i)    To include any prospectus required by section 10(a)(3)
                         of the Securities Act of 1933;

                  (ii)   To reflect in the prospectus any facts or events
                         arising after the effective date of the registration
                         statement (or the most recent post-effective amendment
                         thereof) which, individually or in the aggregate,
                         represent a fundamental change in the information set
                         forth in the registration statement;

                  (iii)  To include any material information with respect to
                         the plan of distribution not previously disclosed in
                         the registration statement or any material change to
                         such information in the registration statement;

                  Provided, however, that paragraphs (1)(i) and (1)(ii) do not
                  apply if the registration statement is on Form S-3 or Form
                  S-8, and the information required to be included in a
                  post-effective amendment by those paragraphs is contained in
                  periodic reports filed by the registrant pursuant to section
                  13 or section 15(d) of the Securities Exchange Act of 1934
                  that are incorporated by reference in the registration
                  statement;

                  (2) That, for the purpose of determining any liability under
                  the Securities Act of 1933, each such post-effective
                  amendment shall be deemed to be a new registration statement
                  relating to the securities offered therein, and the offering
                  of such securities at that time shall be deemed to be the
                  initial bona fide offering thereof; and

                  (3) To remove from registration by means of a post-effective
                  amendment any of the securities being registered which remain
                  unsold at the termination of the offering.

         (b)      Filings incorporating subsequent Exchange Act Documents by
                  Reference.

         The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered herein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

                                     -----

         Insofar as indemnification for liabilities arising under the
Securities Act of 1933, as amended (the "1933 Act") may be permitted to
directors, officers and controlling persons of the registrant pursuant to the
foregoing provisions, or otherwise, the registrant has been advised that in the
opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the 1933 Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the registrant of expenses incurred or
paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such



                                      -4-
   5

indemnification by it is against public policy as expressed in the 1933 Act and
will be governed by the final adjudication of such issue.

     Section 1. Place of Meetings. Meetings of the stockholders for the
election of directors or for any other purpose shall be held at such time and
place, either within or without the State of Delaware, as shall be designated
from time to time by the Board of Directors and stated in the notice of the
meeting or in a duly executed waiver of notice thereof.

     Section 2. Annual Meetings. The annual meeting of stockholders (the
"Annual Meeting of Stockholders") shall be held on such date and at such time
as shall be designated from time to time by the Board of Directors and stated
in the notice of the meeting, at which meeting Directors shall be elected in
accordance with the provisions of that certain Amended and Restated
Stockholders Agreement dated as of March 4, 1997 (the "Amended and Restated
Stockholders Agreement") among the Corporation, Vestar Equity Partners, L.P., a
Delaware limited partnership ("Vestar"), Harvard Private Capital Holdings,
Inc., a Massachusetts Corporation ("Harvard") and American Industrial Partners
Capital Fund II, L.P., a Delaware limited partnership ("AIP"), (for as long as
the Stockholders Agreement shall be in effect) these By-Laws and applicable law
and such other business as may properly be brought before the meeting shall be
transacted. Written notice of the Annual Meeting of Stockholders stating the
place, date and hour of the meeting shall be given to each stockholder entitled
to vote at such meeting not less than ten nor more than sixty days before the
date of the meeting.

     Section 3. Special Meetings. Unless otherwise prescribed by law, special
meetings of stockholders ("Special Meetings of Stockholders"), for any purpose
or purposes, may be called by (i) the Chairman, if there be one, (ii) the
President, (iii) Directors constituting not less than half of the members of
the Board of Directors then in office or (iv) stockholders owning a majority of
the capital stock of the Corporation issued and outstanding and entitled to
vote, in each case by delivering a written request to the Secretary. Such
request shall state the
   2
purpose or purposes of the proposed meeting. At any time, upon the written
request of any person or persons who have duly called a Special Meeting of
Stockholders, it shall be the duty of the Secretary to fix the date of the
Meeting, to be held not more than 75 days after the receipt of the request, and
to give due notice thereof. Special Meetings of Stockholders shall be held at

which the Meeting is called shall be given not less than ten nor more than
sixty days before the date of the Meeting to each stockholder entitled to vote
at such Meeting.

     Section 4. Quorum. Except as otherwise provided by law or by the Restated

the Corporation issued and outstanding and entitled to vote thereat, present in
person or represented by proxy, shall constitute a quorum at all meetings of
the stockholders for the transaction of business. If, however, such quorum
shall not be present or represented at any meeting of the stockholders, the
stockholders entitled to vote thereat, present in person or represented by
proxy, shall have power to adjourn the meeting from time to time, without
notice other than announcement at the meeting, until a quorum shall be present
or represented. At such adjourned meeting at which a quorum shall be present or
represented, any business may be transacted which might have been transacted at
the meeting as originally noticed. If the adjournment is for more than thirty
days, or if after the adjournment a new record date is fixed for the adjourned
meeting, a notice of the adjourned meeting shall be given to each stockholder
entitled to vote at the meeting.

     Section 5. Voting. Unless otherwise required by law, the Certificate of
Incorporation, these By-Laws or any Certificate of Designation with respect to
any preferred stock of the Corporation ("Preferred Stock"), any question
brought before any meeting of stockholders shall be decided by the vote of the
holders of a majority of the stock represented and entitled to vote thereat.
Each stockholder represented at a meeting of stockholders shall be entitled to
cast one vote for each share of the capital stock entitled to vote thereat held
by such stockholder. Such votes may be cast in person or by proxy but no proxy
shall be voted on or after three years from its date, unless such proxy
provides for a longer period. The Board of Directors, in its discretion, or the

interest in such share or shares on the part of any other person, whether or
not it shall have express or other notice thereof, except as otherwise provided
by law.

     Section 2. Waivers of Notice. Whenever any notice is required by law, the
Certificate of Incorporation or these By-Laws, to be given to any director,

                                  ARTICLE VII

                               GENERAL PROVISIONS

     Section 1. Dividends. Dividends upon the capital stock of the Corporation,
subject to the provisions of the Certificate of Incorporation, if any, may be

of any dividend, there may be set aside out of any funds of the Corporation
available for dividends such sum or sums as the Board of Directors from time to
time, in its absolute discretion, deems proper as a reserve or reserves to meet
contingencies, or for equalizing dividends, or for repairing or maintaining any
property of the Corporation, or for any proper purpose, and the Board of
Directors may modify or abolish any such reserve.

     Section 2. Disbursements. All checks or demands for money and notes of the
Corporation shall be signed by such officer or officers or such other person or
persons as the Board of Directors may from time to time designate.

     Section 3. Fiscal Year. The fiscal year of the Corporation shall be

     Section 4. Corporate Seal. The corporate seal shall have inscribed thereon
the name of the Corporation, the year of its organization and the words

thereof to be impressed or affixed or reproduced or otherwise.

                                  ARTICLE VIII

                                INDEMNIFICATION

     Section 1. Power to Indemnify in Actions, Suits or Proceedings other Than
Those by or in the Right of the Corporation. Subject to Section 3 of this
Article VIII, the Corporation shall indemnify any person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action, suit or proceeding, whether civil, criminal,

                                      -11-
   12
administrative or investigative (other than an action by or in the right of the
Corporation) by reason of the fact that he is or was a director or officer of
the Corporation, or is or was a director or officer of the Corporation serving
at the request of the Corporation as a director or officer of another
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise, against expenses (including attorneys' fees), payments, 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 lawful. The
termination of any action, suit or proceeding by payment, order, settlement,
conviction or upon a plea of nolo contendre or its equivalent, shall not, of
itself, create a presumption that the person did not act in good faith and in a
manner which he reasonably believed to be in or not opposed to the best
interests of the Corporation, and, with respect to any criminal action or
proceeding, had reasonable cause to believe that his conduct was unlawful.

     Section 2. Power to Indemnify in Actions, Suits or Proceedings by or in
the Right of the Corporation. Subject to Section 3 of this Article VIII, the
Corporation shall indemnify any person who was or is a party or is threatened
to be made a party to any threatened, pending or completed action or suit by or
in the right of the Corporation to procure a judgment in its favor by reason of
the fact that he is or was a director or officer of the Corporation, or is or
was a director or officer of the Corporation serving at the request of the
Corporation as a director or officer of another corporation, partnership, joint
venture, trust, employee benefit plan or other enterprise against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the Corporation; except that no indemnification shall be
made in respect of any claim, issue or matter as to which such person shall
have been adjudged to be liable to the Corporation unless and only to the
extent that the court of Chancery or the court in which such action or suit was
brought shall determine upon application that, despite the adjudication of
liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which the Court
of Chancery or such other court shall deem proper.

     Section 3. Authorization of Indmenification. Any indemnification under
this Article VIII (unless ordered by a court) shall be made by the Corporation
only as authorized in the specific case upon a determination that
indemnification of the director or officer is proper in the circumstances
because he has met the applicable standard of conduct set forth in Section 1 or
Section 2 of this Article VIII, as the case may be. Such determination shall be
made (i) by a majority vote of the directors who are not parties to such
action, suit or proceeding, even though less than a quorum, or (ii) if there
are no such directors, or if such directors so direct, by independent legal
counsel in a written opinion, or (iii) by the stockholders. To the extent,
however, that a director or officer of the Corporation has been successful on
the merits or otherwise in defense of any action, suit or proceeding described
above, or in defense of any claim, issue or matter therein, he shall be
indemnified against expenses (including attorneys' fees) actually and
reasonably incurred by him in connection therewith, without the necessity of
authorization in the specific case.

     Section 4. Good Faith Defined. For purposes of any determination under
Section 3 of this Article VIII, a person shall be deemed to have acted in good
faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the Corporation, or, with respect to any criminal action or
proceeding, to have had no reasonable cause to believe his conduct was
unlawful, if his action is based on the records or books of account of the
Corporation or another enterprise, or on information supplied to him by the
officers of the Corporation or another enterprise in the course of their
duties, or on the advice of legal counsel for the Corporation or another
enterprise is on information or records given or reports made to

                                      -12-
   13
the Corporation or another enterprise by an independent certified public
accountant or by an appraiser or other expert selected with reasonable care by
the Corporation or another enterprise. The term "another enterprise" as used in
this Section 4 shall mean any other corporation or any partnership, joint
venture, trust, employee benefit plan or other enterprise of which such person
is or was serving at the request of the Corporation as a director or officer.
The provisions of this Section 4 shall not be deemed to be exclusive or to
limit in any way the circumstances in which a person may be deemed to have met
the applicable standard of conduct set forth in Sections 1 or 2 of this Article
VIII, as the case may be.

     Section 5. Indemnification by a Court. Notwithstanding any contrary
determination in the specific case under Section 3 of this Article VIII, and
notwithstanding the presence of any determination thereunder, any director or
officer may apply to any court of competent jurisdiction in the State of
Delaware for indemnification to the extent otherwise permissible under Sections
1 or 2 of this Article VIII. The basis of such indemnification by a court shall
be a determination by such court that indemnification of the director or officer
is proper in the circumstances because he has met the applicable standards of
conduct set forth in Sections 1 or 2 of this Article VIII, as the case may be.
Neither a contrary determination in the specific case under Section 3 of this
Article VIII nor the absence of any determination thereunder shall be a defense
to such application or create a presumption that the director or officer
seeking indemnification has not met any, applicable standard of conduct. Notice
of any application for indemnification pursuant to this Section 5 shall be
given to the Corporation promptly upon the filing of such application. If
successful, in whole or in part, the director or officer seeking indemnification
shall also be entitled to be paid the expense of prosecuting such application.

     Section 6. Expenses Payable in Advance. Expenses incurred by a director or
officer in defending or investigating a threatened or pending action, suit or
proceeding shall be paid by the Corporation in advance of the final disposition
of such action, suit or proceeding upon receipt of an undertaking by or on
behalf of such director or officer to repay such amount if it can ultimately be
determined that he is not entitled to be indemnified by the Corporation as
authorized in this Article VIII.

     Section 7. Non-exclusivity of Indemnification and Advancement of Expenses.
The indemnification and advancement of expenses provided by or granted pursuant
to this Article VIII shall not be deemed exclusive of any other rights to which
those seeking indemnification or advancement of expenses may be entitled under
any By-Law, agreement, contract, vote of stockholders or disinterested
directors or pursuant to the direction (howsoever embodied) of any court of
competent jurisdiction or otherwise, both as to action in his official capacity
and as to action in another capacity while holding such office, it being the
policy of the Corporation that indemnification of the persons specified in
Sections 1 and 2 of this Article VIII shall be made to the fullest extent
permitted by law. The provisions of this Article VIII shall not be deemed to
preclude the indemnification of any person who is not entitled in Sections 1 and
2 of this Article VIII but whom the Corporation has the power or obligation to
indemnify under the provisions of the General Corporation Law of the State of
Delaware, or otherwise.

     Section 8. Insurance. The Corporation may purchase or maintain insurance
on behalf of any person who is or was a director or officer of the Corporation,
or is or was a director or officer of the Corporation serving at the request of
the Corporation as a director or officer of another corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise against any
liability asserted against him and incurred by him in any such capacity, or
arising out of his status as such, whether or not the Corporation would have
the right or obligation to indemnify him against such liability under the
provisions of this Article VIII.

     Section 9. Certain Definitions. For purposes of this Article VIII,
references to "the Corporation" shall include, in connection to the resulting
corporation, any constituent

                                      -13-
   14
corporation (including any constituent of a constituent) absorbed by
consolidation or merger which, if its separate existence had continued, would
have had power and authority to indemnify its directors or officers, so that any
person who is or was a director or officer of such constituent corporation, or
is or was a director or officer of such constituent corporation serving at the
request of such constituent corporation as a director or officer of another
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise, shall stand in the same position under the provisions of this
Article VIII with respect to the resulting or surviving corporation as he would
have with respect to such constituent corporation if its separate existence had
continued. For purposes of this Article VIII, references to "fines" shall
include any excise taxes assessed on a person with respect to an employee
benefit plan; and references to "serving at the request of the Corporation"
shall include any service as a director or officer of the Corporation which
imposes duties on, or involves services by, such director or officer with
respect to an employee benefit plan, its participants or beneficiaries; and a
person who acted in good faith and in a manner he reasonable believed to be in
the interest of the participants and beneficiaries of an employee benefit plan
shall be deemed to have acted in a manner "not opposed to the best interests of
the Corporation" as referred to in this Article VIII.

     Section 10. Survival of Indemnification an Advancement of Expenses. The
indemnification and advancement of expenses provided by, or granted pursuant
to, this Article VIII shall, unless otherwise provided when authorized or
ratified, continue as to a person who has ceased to be a director or officer
and shall inure to the benefit of the heirs, executors and administrators of
such a person.

     Section 11. Limitation on Indemnification. Notwithstanding anything
contained in this Article VIII to the contrary, except for proceedings to
enforce rights to indemnification (which shall be governed by Section 5
hereof), the Corporation shall not be obligated to indemnify any director or
officer in connection with a proceeding (or part thereof) initiated by such
person unless such proceeding (or part thereof) was authorized or consented to
by the Board of Directors of the Corporation.

     Section 12. Indemnification of Employees and Agents. The Corporation may,
to the extent authorized from time to time by the Board of Directors, provide
rights to indemnification and to the advancement of expenses to employees and
agents of the Corporation similar to those conferred in this Article VIII to
directors and officers of the Corporation.


                                   ARTICLE IX

                                   AMENDMENTS     

     SECTION 1. Subject to Section 1(j) of Article III hereof, these By-Laws
may be altered, amended or repealed, in whole or in part, or new By-Laws may be
adopted by the stockholders or by the Board of Directors, provided, however,
that notice of such alteration, amendment, repeal or adoption of new By-Laws be
contained in the notice of such meeting of stockholders or Board of Directors
as the case may be. All such amendments must be approved be either the holders
of a majority of the outstanding capital stock entitled to vote thereon or by a
majority of the entire Board of Directors then in office. Notwithstanding the
foregoing, Article VIII hereof shall not be altered, amended or repealed in
whole or in part, unless such alteration, amendment or repeal is approved by
the stockholders of the Corporation pursuant to a vote which would be
sufficient to adopt an amendment to the Restated Certificate of Incorporation
of the Corporation.


                                      -14-
   15
     Section 2. Entire Board of Directors. As used in this Article IX and in
these By-Laws generally, the term "entire Board of Directors" means the total
number of directors which the Corporation would have if there were no vacancies.

Westinghouse Air Brake Company
1001 Air Brake Avenue
Wilmerding, PA  15148-0001

                  Registration Statement on Form S-8 re
                  1997 Executive Retirement Plan
                  -------------------------------------

Gentlemen:

                  We have acted as special counsel to Westinghouse Air Brake
Company (the "Company") in connection with the above-captioned Registration
Statement (the "Registration Statement") relating to up to 200,000 shares of
Common Stock, par value $.01 per share, of the Company (the "Common Stock")
which may be issued to employees of the Company under the Company's 1997
Executive Retirement Plan (the "Plan"). The Plan provides that only reacquired
shares of Common Stock may be issued under the Plan. In rendering our opinion
below, we have assumed that any previously issued shares reacquired by the
Company and used under the Plan will have been duly authorized, validly issued
and fully paid at the time of their original issuance.

                  In connection with this opinion, we have examined, among
other things:

                  (1) the Certificate of Incorporation of the Company, as
         amended to date;

                  (2) resolutions adopted by the Board of Directors of the
         Company on October 22, 1997 adopting the Plan; and

                  (3) the Plan, as currently in effect.

                  Based upon the foregoing and upon an examination of such
other documents, corporate proceedings, statutes, decisions and questions of
law as we considered necessary in order to enable us to furnish this opinion,
and subject to the assumptions set forth above, we are pleased to advise you
that in our opinion:

                  (a) The Company has been duly incorporated and is a validly
         existing corporation under the laws of the State of Delaware; and

                  (b) The shares of Common Stock being registered and which may
         be issued by the Company pursuant to the provisions of the Plan have
         been duly authorized, and upon such issuance in accordance with the
         provisions of the Plan such shares will be validly issued, fully paid
         and nonassessable.
