                      RATIOS OF EARNINGS TO FIXED CHARGES

     The ratios of earnings to fixed charges are computed by dividing income
from continuing operations before income taxes and fixed charges, as adjusted
for certain equity method investments, by fixed charges. Fixed charges consist
of interest on all indebtedness, including capital lease obligations,
amortization of debt expenses and a percentage of rental expense of operating
leases that represents interest. Our consolidated ratios of earnings to fixed
charges for each of the periods indicated are as follows:

                                USE OF PROCEEDS

     Unless otherwise indicated in an accompanying prospectus supplement, we
expect to use the net proceeds from the sale of the securities for general
corporate purposes, which may include, among other things:

     - the repayment of outstanding indebtedness;

     - working capital;

     - capital expenditures;

     - the repurchase of shares of common stock; and

     - acquisitions.

The precise amount and timing of the application of such proceeds will depend
upon our funding requirements and the availability and cost of other funds.

                          THE SECURITIES WE MAY OFFER

     The descriptions of the securities contained in this prospectus, together
with the applicable prospectus supplements, summarize all the material terms and
provisions of the various types of securities that we may offer. The particular
terms of the securities offered by any prospectus supplement will be described
in the prospectus supplement relating to the securities. If indicated in the
applicable prospectus supplement, the terms of the securities may differ from
the terms summarized below. The prospectus supplement will also contain
information, where applicable, about material United States federal income tax
considerations relating to the securities, and the securities exchange, if any,
on which the securities will be listed.

     We may sell from time to time, in one or more offerings:

     - common stock;

     - preferred stock;

     - depositary shares;

     - debt securities;

     - warrants to purchase any of the securities listed above;

     - stock purchase contracts to purchase common stock, preferred stock or
       depositary shares; and/or

     - stock purchase units consisting of a stock purchase contract and either
       debt securities or debt obligations of certain third parties.

     In this prospectus, we will refer to the common stock, preferred stock,
depositary shares, debt securities, warrants, stock purchase contracts and stock
purchase units collectively as "securities." The total dollar amount of all
securities that we may issue will not exceed $500,000,000.

     If we issue debt securities at a discount from their original stated
principal amount, then, for purposes of calculating the total dollar amount of
all securities issued under this prospectus, we will treat the initial offering
price of the debt securities as the total original principal amount of the debt
securities.

     This prospectus may not be used to consummate a sale of securities unless
it is accompanied by a prospectus supplement.

incorporated by reference into the registration statement which includes this
prospectus. The terms of these securities may also be affected by the
Massachusetts General Laws. While the terms summarized below will apply
generally to any future common stock or preferred stock that we may offer, the
particular terms of any series of these securities will be described in more
detail in the applicable prospectus supplement and may vary from the terms
summarized below.

     Under our charter our authorized capital stock consists of 100,000,000
shares of common stock, $1.00 par value per share, and 1,000,000 shares of
preferred stock, $1.00 par value per share. We will describe the specific terms
of any common stock or preferred stock we may offer in a prospectus supplement.
If indicated in a prospectus supplement, the terms of any common stock or
preferred stock offered under that prospectus supplement may differ from the
terms described below.

COMMON STOCK

     As of May 2, 1999, EG&G had 45,216,000 shares of common stock issued and
outstanding. Each outstanding share of common stock currently has attached to it
one preferred share purchase right issued under our stockholder rights plan,
which is summarized below. All outstanding shares of common stock are duly
authorized, validly issued, fully paid and nonassessable.

  VOTING

     For all matters submitted to a vote of stockholders, each holder of common
stock is entitled to one vote for each share registered in his or her name on
the books of EG&G. Our common stock does not have cumulative voting rights. As a
result, subject to the voting rights of any outstanding preferred stock, of
which there currently is none, persons who hold more than 50% of the outstanding
common stock entitled to elect members of the board of directors can elect all
of the directors who are up for election in a particular year.

  DIVIDENDS

     If our board of directors declares a dividend, holders of common stock will
receive payments from the funds of EG&G that are legally available to pay
dividends. However, this dividend right is subject to any preferential dividend
rights we may grant to the persons who hold preferred stock, if any is
outstanding.

  LIQUIDATION

     If EG&G is dissolved, the holders of common stock will be entitled to share
ratably in all the assets that remain after we pay our liabilities and any
amounts we may owe to the persons who hold preferred stock, if any is
outstanding.

  OTHER RIGHTS AND RESTRICTIONS

     Holders of common stock do not have preemptive rights, and they have no
right to convert their common stock into any other securities. Our common stock
is not subject to redemption by EG&G. Our charter and bylaws do not restrict the
ability of a holder of common stock to transfer his or her shares of common
stock.

     When we issue shares of common stock, the shares will be fully paid and
non-assessable. Massachusetts law provides that, if we make a distribution to
our stockholders other than a distribution of our capital stock, when we are
insolvent, or that renders us insolvent, then our stockholders would be required
to pay back to us the amount of the distribution we made to them, or the portion
of the distribution that causes us to become insolvent.

  LISTING

     Our common stock is listed on the NYSE.

  TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for our common stock is Boston EquiServe,
L.P.

PREFERRED STOCK

     As of May 2, 1999, we had no shares of preferred stock outstanding. Our
charter authorizes our board of directors to issue preferred stock in one or
more series and to determine the voting rights and dividend rights, dividend
rates, liquidation preferences, conversion rights, redemption rights, including
sinking fund provisions and redemption prices, and other terms and rights of
each series of preferred stock. The general terms of our undesignated preferred
stock are described below under the caption "-- Undesignated Preferred Stock."

     As of the date of this prospectus, our board of directors had designated
70,000 shares of preferred stock as "Series C Junior Participating Preferred
Stock" in connection with our stockholder rights plan. The rights, preferences
and privileges of the Series C Preferred Stock are described below.

  SERIES C PREFERRED STOCK

     Our Board has reserved the Series C Preferred Stock for issuance in
connection with our stockholder rights plan, which is described below. As of
March 5, 1999, there were no shares of Series C Preferred Stock outstanding. The
following description is a summary of all the material terms of our Series C
Preferred Stock. It does not restate these terms in their entirety. We urge you
to read our charter because it, and not this description, defines the rights of
holders of Series C Preferred Stock. We have filed a copy of our charter as an
exhibit to the registration statement which includes this prospectus. This
summary of our Series C Preferred Stock is not complete and is qualified by
reference to our charter.

     VOTING. Each share of Series C Preferred Stock is entitled to 1,000 votes,
subject to adjustment. Except as provided below, each share of Series C
Preferred Stock votes together with the holders of common stock and all other
capital stock of EG&G on all matters voted on by stockholders.

     In the event that we fail to pay six quarterly dividends on the Series C
Preferred Stock, the holders of the Series C Preferred Stock, voting as a single
class, will have the right to elect two members of our board of directors. Any
director elected by the holders of Series C Preferred Stock may be removed with
or without cause by such holders. The terms of all directors elected under this
provision will terminate when the dividend arrearage is fully paid and, in
addition, we have paid at least one regular dividend after the curing of the
arrearage.

     Without the vote of at least two-thirds of the outstanding shares of Series
C Preferred Stock, we may not alter or repeal any provisions in our charter so
as to adversely affect the rights of the Series C Preferred Stock.

     DIVIDENDS.  With respect to the payment of dividends and the distribution
of assets, the Series C Preferred Stock ranks junior to all series of all other
series of preferred stock, unless the terms of a particular series provide
otherwise. The holders of shares of Series C Preferred Stock are entitled to
cash dividends equal to the greater of (a) $1.00 or (b) 1,000 times the per
share amount of all cash dividends and 1,000 times the per share amount of all
non-cash dividends, other than dividends payable in common stock or by a
subdivision of the outstanding common stock, which have been declared on the
common stock since the preceding quarterly dividend payment date. Dividends on
the Series C Preferred Stock are payable quarterly on the first day of March,
June, September and December each year.

     Our board of directors must declare a dividend on the Series C Preferred
Stock after it declares any dividend on the common stock, other than dividends
payable in common stock. However, if our board of directors does not declare a
dividend on the common stock during the period between quarterly dividend
payment dates, a dividend
                                       -7-
<PAGE>   11

of $1.00 per share of Series C Preferred Stock will still be payable on the
following quarterly dividend payment date. Dividends begin to accrue and
accumulate on outstanding shares of Series C Preferred Stock from the quarterly
dividend payment date preceding the date of issuance of such shares.

     LIQUIDATION. If EG&G liquidates, dissolves or winds up, then:

     - we must pay the holders of outstanding shares of Series C Preferred
       Stock, before we make any payment to the holders of shares of stock
       ranking junior to the Series C Preferred Stock, an amount equal to $1,000
       per share, plus all unpaid accrued dividends or, if greater, an amount
       equal to 1,000 times the amount to be paid to holders of common stock;
       and

     - we may not make any distribution to the holders of shares of stock
       ranking on a parity with the Series C Preferred Stock, except for
       distributions made ratably to the holders of Series C Preferred Stock and
       other preferred stocks.

     For purposes of this liquidation preference, neither the consolidation,
merger or other business combination of EG&G with another entity nor the sale of
all or any of our property, assets or business will be treated as a liquidation,
dissolution or winding up of EG&G.

     MERGER, CONSOLIDATION, ETC. If we are a party to any merger, consolidation
or similar transaction in which shares of common stock are exchanged or changed
into stock or securities of another entity, cash or property of another entity,
then the Series C Preferred Stock will be exchanged or changed into an amount
per share equal to 1,000 times the amount of consideration into which or for
which each share of common stock is changed or exchanged in such merger,
consolidation or similar transaction.

     ADJUSTMENTS FOR STOCK SPLITS AND OTHER EVENTS. In the event that we declare
a dividend on our common stock that is payable in common stock or we effect a
subdivision, combination or consolidation of the outstanding shares of our
common stock into a greater or lesser number of shares, then the dividend,
liquidation and merger or consolidation amounts payable to holders of Series C
Preferred Stock will be increased or reduced in proportion to the resulting
increase or decrease in the total number of shares of common stock outstanding.

     CERTAIN RESTRICTIONS. If any quarterly dividends payable on the Series C
Preferred Stock are in arrears, then, until all of these unpaid dividends have
been paid in full, we may not:

     - declare or pay dividends on any shares of stock ranking junior to the
       Series C Preferred Stock;

     - declare or pay any dividends on any shares of stock ranking on a parity
       with the Series C Preferred Stock, except ratably among all of these
       parity stocks;

     - redeem any stock ranking junior to the Series C Preferred Stock, unless
       we redeem the junior stock by issuing additional shares of stock ranking
       junior to the Series C Preferred Stock; or

     - redeem any shares of Series C Preferred Stock or shares of stock ranking
       on a parity with the shares of Series C Preferred Stock, except in
       accordance with a purchase offer to all holders of these series or
       classes upon terms that the board of directors deems fair and equitable.

     We may not permit any of our subsidiaries to purchase any shares of EG&G
stock, unless we are able at such time to purchase shares in accordance with the
terms described in the preceding paragraph.

     REDEMPTION. We may not redeem the Series C Preferred Stock.

     FRACTIONAL SHARES. We may issue the Series C Preferred Stock in fractions
of a single share, but each fraction must be a multiple of one one-thousandth of
a share. Each fractional share of Series C Preferred Stock will have
proportionate voting, dividend,
                                       -8-

liquidation and other rights as discussed above.

  UNDESIGNATED PREFERRED STOCK

     This summary of the undesignated preferred stock relates to terms and
conditions that we expect will apply to all series of the preferred stock
offered under this prospectus. The applicable prospectus supplement will
describe the particular terms of any series of preferred stock offered. If
indicated in the prospectus supplement, the terms of any series may differ from
the terms described below.

     The following description, together with the applicable prospectus
supplements, summarizes all the material terms and provisions of any preferred
stock being offered by this prospectus. It does not restate the terms and
provisions in their entirety. We urge you to read our charter and the applicable
certificate of designation because they, and not this description, define the
rights of any holders of preferred stock. We have filed our charter as an
exhibit to the registration statement which includes this prospectus. We will
incorporate by reference as an exhibit to the registration statement the form of
any certificate of designations before the issuance of any series of preferred
stock.

     GENERAL.  The applicable prospectus Supplement will describe the following
terms of each series of preferred stock:

     - the designation of the series and the number of shares offered;

     - the amount of the liquidation preference per share;

     - the initial public offering price of the shares to be sold;

     - the dividend rate applicable to the series, the dates on which dividends
       will be payable and the dates from which dividends will begin to
       accumulate, if any;

     - any redemption or sinking fund provisions;

     - any conversion or exchange rates;

     - any antidilution provisions;

     - any additional voting and other rights, preferences, privileges and
       restrictions;

     - any listing of the series on an exchange;

     - the relative ranking of the series as to dividend rights and rights upon
       liquidation, dissolution or winding up of EG&G; and

     - any other terms of the series.

     Upon receipt of the purchase price, the shares of preferred stock that we
issue will be fully paid and nonassessable. The liquidation price or preference
of any series of preferred stock is not indicative of the price at which the
shares will actually trade after the date of issuance.

     Although our board of directors has no intention at the present time of
doing so, it could issue a series of preferred stock that could impede the
completion of a merger, tender offer or other takeover attempt. Our board of
directors will issue preferred stock under these circumstances only if it
determines that the issuance is in the best interests of EG&G and its
stockholders. In addition, the terms of a series of preferred stock might
discourage a potential acquiror from attempting to acquire EG&G in a manner that
changes the composition of our board of directors, even when a majority of our
stockholders believe that an acquisition under these circumstances would be in
their best interests or when stockholders would receive a premium for their
stock over the then current market price.

     The NYSE currently requires us to obtain the approval of our stockholders
before listing securities for trading on the NYSE under some circumstances,
including:

     - some issuances to our directors, officers, substantial security holders
       and other closely-related parties;

     - issuances relating to a private sale of our common stock at a price below
       the book or fair market value of our common stock that increase the total
       number of shares of our common stock outstanding by 20% or more; and
                                       -9-
<PAGE>   13

     - issuances that will result in a change of control of EG&G.

     VOTING. Except as described below, no series of preferred stock will have
voting rights. Under Massachusetts law, however, a holder of our capital stock
is generally entitled to vote whenever an amendment of our charter would
adversely affect the rights of the class of securities held by the holder. If we
wish to amend our charter and the amendment would adversely affect the rights of
a particular class or series of our capital stock, we would be required to
obtain the affirmative vote of at least two-thirds of the shares of that class
or series. Under these circumstances, all series of a class of capital stock
that are adversely affected in the same manner vote together as one class, and
any other series that is adversely affected in a different manner votes as a
separate class.

     Without the vote of the holders of two-thirds of the then outstanding
shares of a series of preferred stock voting as a single class together with the
holders of shares of all other series of preferred stock entitled to vote on the
following matters, we may not:

     - authorize or issue any shares of a class or series of stock ranking
       senior to the series of preferred stock; or

     - approve any amendment to our charter or applicable certificate of
       designations, which would materially and adversely affect the series of
       preferred stock.

     An amendment which (a) increases the number of authorized shares or
authorizes the creation or issuance of any stock ranking junior to or on a
parity with such series of preferred stock, or (b) reflects a change in control
of EG&G in which EG&G is not the surviving entity, will not be deemed to
materially and adversely affect such series of preferred stock.

     In addition, if six quarterly dividend payments on a series of preferred
stock have accrued but remain unpaid, then the holders of this series of
preferred stock:

     - will have one vote per share; and

     - will have the right, voting together as a single class with the holders
       of shares of all other series of preferred stock entitled to vote for the
       election of directors, other than the Series C Preferred Stock, to elect
       two members to our board of directors.

This voting right will continue until dividends on this series of preferred
stock have been paid in full for four consecutive dividend periods. Directors
elected in this fashion will hold office for a term expiring on the earlier of
the payment by EG&G of dividends on this series of preferred stock for four
consecutive dividend periods or the next annual meeting of stockholders.

     As described below under the caption "Description of Depositary Shares," if
EG&G elects to issue depositary shares, each depositary share will, in effect,
be entitled to a fraction of a vote per depositary share.

     RANK. Each series of preferred stock will, with respect to dividend and
liquidation rights, rank senior to common stock and the Series C Preferred
Stock. All shares of each series of preferred stock will be of equal rank with
each other. Each series of preferred stock may vary as to rank and priority with
other series of preferred stock.

     DIVIDENDS. Holders of each series of preferred stock will be entitled to
receive, if declared by our board of directors, cash dividends, payable on the
dates and at the rates as described in the applicable prospectus supplement.
Dividends will be cumulative and will accrue from the date stated in the
applicable prospectus supplement.

     No dividends may be declared or paid on a series of preferred stock ranking
on a parity with or junior to the series of preferred stock offered by the
applicable prospectus supplement for any period unless dividends have been or
are at the same time declared and paid on the offered series of preferred stock.
Any dividend paid on a series of preferred stock and any other parity preferred
stock in an amount that is less than the full amount of the dividend entitled to
be received by this series of preferred stock and other parity preferred stock
will be paid ratably among all holders of this series of preferred
                                      -10-
<PAGE>   14

stock and parity preferred stock. We will not pay any interest on any dividends
that are in arrears.

     If we have not paid dividends in full on the series of preferred stock
offered by the applicable prospectus supplement, then we may not:

     - declare or pay cash dividends on any junior stock, including common stock
       and Series C Preferred Stock;

     - repurchase or redeem any shares of junior stock or pay any monies into a
       sinking fund for the redemption of any of these shares, unless we convert
       or exchange the repurchased or redeemed stock for junior stock; or

     - repurchase or redeem any series of preferred stock ranking on a parity
       with the offered series of preferred stock or pay any monies into a
       sinking fund for the redemption of any of these shares, unless we (a)
       repurchase or redeem on a pro rata basis all or a part of the outstanding
       parity preferred stock or (b) convert or exchange the redeemed or
       repurchased stock for junior stock.

     Any dividend payment made on a series of preferred stock will first be
credited against the earliest accrued but unpaid dividends due on the series.

     LIQUIDATION.  Unless otherwise specified in the applicable prospectus
supplement, if EG&G liquidates, dissolves or winds up, then the holders of a
series of preferred stock will be entitled to receive, subject to the rights of
creditors, but before any payment to the holders of common stock or any other
junior stock, an amount equal to the liquidation preference per share described
in the applicable prospectus supplement. In addition to this liquidation
preference, holders of preferred stock will also be entitled to receive accrued
and unpaid dividends on their shares of preferred stock, if such dividends are
cumulative.

     If the amounts available for distribution upon liquidation, dissolution or
winding up of EG&G are not sufficient to satisfy the full liquidation rights of
all outstanding series of preferred stock and all stock ranking on a parity with
this preferred stock, then the holders of each series of stock will share
ratably in the distribution, which, in the case of preferred stock, may include
a cumulative dividend.

     After payment of the full amount of the liquidation preference, the holders
of a series of preferred stock will not be entitled to any further participation
in the distribution of assets by EG&G.

     CONVERSION OR EXCHANGE. The terms, if any, on which preferred stock of any
series may be converted or exchanged for another class or series of securities
will be described in the applicable prospectus supplement.

     REDEMPTION. The applicable prospectus supplement will describe the terms,
if any, on which we may redeem any series of preferred stock. We will cancel all
redeemed or repurchased shares of a series of preferred stock and restore these
shares to the status of authorized but unissued shares of preferred stock.

     OTHER RIGHTS. The applicable prospectus supplement will describe any other
preferences, voting powers or relative participating, optional or other special
rights of a series of preferred stock. The holders of preferred stock will not
have any preemptive rights to subscribe for any securities of EG&G.

     TITLE. EG&G, the transfer agent and registrar for a series of preferred
stock and any agent of EG&G or such transfer agent and registrar may treat the
registered owner of preferred stock of the series as the absolute owner of the
preferred stock for all purposes.

     TRANSFER AGENT AND REGISTRAR. The applicable prospectus supplement will
name the transfer agent and registrar for each series of preferred stock.

STOCKHOLDER RIGHTS PLAN

     On January 25, 1995, our board of directors adopted a stockholder rights
plan. Under our stockholder rights plan, each of our common stockholders
received a dividend

                                      -11-
<PAGE>   15

of one "preferred stock purchase right" for each outstanding share of common
stock that the stockholder owned. We refer to these preferred stock purchase
rights as the "Rights." The Rights trade automatically with our shares of common
stock and become exercisable only under certain circumstances described below.

     The purpose of the Rights is to encourage potential acquirors to negotiate
with our board of directors before attempting a takeover bid and to provide our
board of directors with leverage in negotiating on behalf of our stockholders
the terms of any proposed takeover. The Rights may have certain antitakeover
effects. They should not, however, interfere with any merger or other business
combination approved by our board of directors.

     The following description is a summary of all the material terms of our
stockholder rights plan. It does not restate these terms in their entirety. We
urge you to read our stockholder rights plan because it, and not this
description, defines the terms and provisions of our plan. We have filed a copy
of our rights agreement as an exhibit to our Registration Statement on Form 8-A,
as amended, which was filed with the SEC on February 9, 1995 and which is
incorporated by reference into the registration statement which includes this
prospectus. You may obtain a copy at no charge by writing to us at the address
listed under the caption "Where You Can Find More Information."

  EXERCISE OF RIGHTS

     Until a Right is exercised, the holder of a Right will not have any rights
as a stockholder. When the Rights become exercisable, holders of the Rights will
be able to purchase from us a unit equal to 1/1000th of a share of our Series C
Preferred Stock, at a purchase price of $60 per unit.

     In general, the rights will become exercisable upon the earlier of:

     - ten days following a public announcement by us that a person or group has
       acquired beneficial ownership of 20% or more of the outstanding shares of
       common stock; or

     - ten business days after the beginning of a tender offer or exchange offer
       that would result in a person or group beneficially owning 30% or more of
       the common stock.

  FLIP IN EVENT

     If a person or group becomes the beneficial owner of 20% or more of our
common stock, then each Right will then entitle its holder to receive, upon
exercise, a number of shares of our common stock which is equal to (a) the
exercise price of the right divided by (b) one-half of the market price of our
common stock on the date of the occurrence of this event. We refer to this
occurrence as a "flip in event." A flip in event does not occur if there is an
offer for all of our outstanding shares of common stock that our board of
directors determines is fair to our stockholders and in EG&G's best interests.

  FLIP OVER EVENT

     If at any time after a person or group becomes the beneficial owner of 20%
or more of our common stock, (a) EG&G is acquired in a merger or other
transaction in which EG&G does not survive or in which our common stock is
changed or exchanged or (b) 50% or more of EG&G's assets or earning power is
sold or transferred, then each holder of a Right will be entitled to receive,
upon exercise, a number of shares of common stock of the acquiring company in
the transaction equal to (1) the exercise price of the Right divided by (2)
one-half of the market price of the acquiring company's common stock on the date
of the occurrence of this event. This exercise right will not occur if the
merger or other transaction follows an offer for all of our outstanding shares
of common stock that our board of directors determines is fair to our
stockholders and in EG&G's best interests.

  EXCHANGE OF RIGHTS

     At any time after a flip in event, our board of directors may exchange the
Rights by

                                      -12-
<PAGE>   16

providing to the holder one share of our common stock or one one-thousandth of a
share of our Series C Preferred Stock for each of the holder's Rights.

  REDEMPTION OF RIGHTS

     At any time until ten days after the date on which a person or group
acquires beneficial ownership of 20% or more of the outstanding shares of our
common stock, we may redeem the Rights at a price of $.01 per Right. The Rights
will expire on the close of business on February 8, 2005, subject to earlier
expiration or termination as described in our stockholder rights plan.

CERTAIN PROVISIONS OF EG&G'S
BYLAWS AND MASSACHUSETTS LAW

  EG&G'S BYLAWS

     EG&G's bylaws impose restrictions and limitations on the ability of
stockholders to call special meetings of stockholders. For example, requests for
stockholder meetings may be made only during limited periods of time and must be
made by a group of stockholders holding at least 40%, or, if less, the maximum
percentage permitted by law, of the outstanding capital stock entitled to vote
at the meeting.

  BUSINESS COMBINATIONS WITH INTERESTED STOCKHOLDERS

     The Massachusetts General Laws contain antitakeover provisions regarding,
among other things, business combinations with an affiliated stockholder. In
general, the Massachusetts General Laws prevent a publicly held Massachusetts
corporation from engaging in a "business combination" as defined in the
Massachusetts General Laws with an "interested stockholder" for a period of
three years after the date of the transaction in which the person became an
interested stockholder, unless:

     - before the date on which the person became an interested stockholder, the
       board of directors of the corporation approved either the business
       combination or the transaction in which the person became an interested
       stockholder;

     - the interested stockholder acquires 90% of the outstanding voting stock
       of the corporation at the time it becomes an interested stockholder; or

     - the business combination is approved by the board of directors and the
       holders of two-thirds of the outstanding voting stock of the corporation
       voting at a meeting, excluding the voting stock owned by the interested
       stockholder.

An "interested stockholder" is generally a person owning more than 5% of the
outstanding voting stock of the corporation. A business combination includes
mergers, consolidations, stock and assets sales and other transactions with the
interested stockholder which result in a financial benefit to the interested
stockholder.

  CONTROL SHARE ACQUISITIONS

     EG&G has elected to opt out of the control share acquisitions provision of
the Massachusetts General Laws. EG&G could, however, opt into these control
share acquisitions provisions at any time by amending its bylaws.

     In general, the control share acquisitions provision of the Massachusetts
General Laws provides that any person, including his or her affiliates, who
acquires shares of a corporation that is subject to the control share
acquisitions statute and whose shares represent one-fifth or more, one-third or
more, or a majority or more of the voting power of the corporation in the
election of directors cannot exercise any voting power with respect to those
shares, or any shares acquired by the person within 90 days before or after an
acquisition of this nature, unless these voting rights are authorized by the
stockholders of the corporation.

     The authorization of voting rights requires the affirmative vote of the
holders of a

                                      -13-
<PAGE>   17

majority of the outstanding voting shares, excluding shares owned by:

     - the person making an acquisition of this nature;

     - any officer of the corporation; and

     - any employee who is also a director of the corporation.

     There are several other types of share acquisitions that are not subject to
this provision of the Massachusetts General Laws, including acquisitions of
shares (a) under a tender offer, merger or consolidation which is made in
connection with an agreement to which the corporation is a party and (b)
directly from the corporation or a wholly owned subsidiary of the corporation.

                        DESCRIPTION OF DEPOSITARY SHARES

     The following description, together with the applicable prospectus
supplements, summarizes all the material terms and provisions of the depositary
shares that we may offer under this prospectus and the related deposit
agreements and depositary receipts. Specific deposit agreements and depositary
receipts will contain additional important terms and provisions and will be
incorporated by reference into the registration statement which includes this
prospectus before we issue any depositary shares.

     This summary of depositary agreements, depositary shares and depositary
receipts relates to terms and conditions applicable to these types of securities
generally. The particular terms of any series of depositary shares will be
summarized in the applicable prospectus supplement. If indicated in the
applicable prospectus supplement, the terms of any series may differ from the
terms summarized below.

GENERAL

     We may elect to offer fractional shares of preferred stock rather than full
shares of preferred stock. If so, we will issue "depositary receipts" for these
"depositary shares." Each depositary share will represent a fraction of a share
of a particular series of preferred stock. Each holder of a depositary share
will be entitled, in proportion to the fraction of preferred stock represented
by that depositary share, to the rights and preferences of the preferred stock,
including dividend, voting, redemption, conversion and liquidation rights. We
will enter into a deposit agreement with a depositary, which will be named in
the related prospectus supplement.

     In order to issue depositary shares, we will issue preferred stock and
immediately deposit these shares with the depositary. The depositary will then
issue and deliver depositary receipts to the persons who purchase depositary
shares. Each whole depositary share issued by the depositary may represent a
fraction of a share of preferred stock held by the depositary. The depositary
will issue depositary receipts in a form that reflects whole depositary shares,
and each depositary receipt may evidence any number of whole depositary shares.

     Pending the preparation of definitive engraved depositary receipts, a
depositary may, upon our written order, issue temporary depositary receipts,
which will temporarily entitle the holders to all the rights pertaining to the
definitive depositary receipts. We will bear the costs and expenses of promptly
preparing definitive depositary receipts and of exchanging the temporary
depositary receipts for such definitive depositary receipts.

DIVIDENDS AND OTHER DISTRIBUTIONS

     The depositary will distribute all cash and non-cash distributions it
receives with respect to the underlying preferred stock to the record holders of
depositary shares in proportion to the number of depositary shares they hold. In
the case of non-cash distributions, the depositary may determine that the
distribution cannot be made proportionately or that it may not be feasible to
make the distribution. If so, the depositary will, with our approval, adopt a
method it deems equitable and practicable to effect the distribution, including
the sale, public or private, of the securities or other non-cash property it
receives in the distribution at a place and on terms it deems proper. The
amounts distributed by the depositary will be reduced by any amount required to
be withheld by EG&G or the depositary on account of taxes.

REDEMPTION OF DEPOSITARY SHARES

     If we redeem the series of preferred stock that underlies the depositary
shares, the depositary will redeem the depositary shares from the proceeds it
receives from the redemption of the preferred stock it holds. The depositary
will redeem the number of depositary shares that represent the amount of
underlying preferred stock that we have redeemed. The redemption price for
depositary shares will be in proportion to the redemption price per share that
we paid for the underlying preferred stock. If we redeem

                                      -15-
<PAGE>   19

less than all of the depositary shares, the depositary will select which
depositary shares to redeem by lot, or some substantially equivalent method.

     After a redemption date is fixed, the depositary shares to be redeemed no
longer will be considered outstanding. The rights of the holders of the
depositary shares will cease, except for the rights to receive money or other
property upon redemption. In order to redeem their depositary shares, holders
will surrender their depositary receipts to the depositary. If we deposit funds
with the depositary to redeem depositary shares, and the holders fail to redeem
their depositary receipts, the depositary will return the money to us within two
years from the date on which we deposited the funds.

VOTING THE PREFERRED STOCK

     We will notify the depositary about any meeting at which the holders of
preferred stock are entitled to vote, and the depositary will mail the
information to the record holders of depositary shares related to that preferred
stock. Each record holder of depositary shares on the record date will be
entitled to instruct the depositary on how to vote the shares of preferred stock
represented by that holder's depositary shares. The depositary will vote the
preferred stock represented by the depositary shares in accordance with these
instructions, provided the depositary receives these instructions sufficiently
in advance of the meeting. If the depositary does not receive instructions from
the holders of the depositary shares, the depositary will abstain from voting
the preferred stock that underlies those depositary shares.

WITHDRAWAL OF PREFERRED STOCK

     When a holder surrenders depositary receipts at the corporate trust office
of the depositary, and pays any necessary taxes, charges or other fees, the
holder will be entitled to receive the number of whole shares of the related
series of preferred stock, and any money or other property, if any, represented
by the holder's depositary shares. Once a holder exchanges depositary shares for
whole shares of preferred stock, that holder cannot "re-deposit" these shares of
preferred stock with the depositary, or exchange them for depositary shares. If
a holder delivers depositary receipts that represent a number of depositary
shares that exceeds the number of whole shares of related preferred stock the
holder seeks to withdraw, the depositary will issue a new depositary receipt to
the holder that evidences the excess number of depositary shares.

AMENDMENT AND TERMINATION OF THE
DEPOSIT AGREEMENT

     EG&G and the depositary can agree, at any time, to amend the form of
depositary receipt and any provisions of the deposit agreement. However, if an
amendment has a material adverse effect on the rights of the holders of related
depositary shares, the holders of at least a majority of the depositary shares
then outstanding must first approve the amendment. Every holder of a depositary
receipt at the time an amendment becomes effective will be bound by the amended
deposit agreement. However, subject to any conditions in the deposit agreement
or applicable law, no amendment can impair the right of any holder of a
depositary share to receive shares of the related preferred stock, or any money
or other property represented by the depositary shares, when they surrender
their depositary receipts.

     We can terminate the deposit agreement at any time, as long as we provide
at least 60 days' prior written notice to the depositary. If we terminate the
deposit agreement, then within 30 days from the date the depositary receives our
notice, the depositary will deliver whole or fractional shares of the related
preferred stock to the holders of depositary shares, when they surrender their
depositary receipts. The deposit agreement will terminate automatically after
all outstanding depositary shares have been redeemed, or, in connection with any
liquidation, dissolution or winding up of EG&G, after the final distribution of
our assets has been made to the holders of the related series of preferred stock
and, in turn, to the holders of depositary shares.

                                      -16-
<PAGE>   20

CHARGES OF DEPOSITARY

     We will pay all transfer and other taxes and the government charges that
relate solely to the depositary arrangements. We will also pay the charges of
each depositary, including charges in connection with the initial deposit of the
related series of preferred stock, the initial issuance of the depositary
shares, and all withdrawals of shares of the related series of preferred stock.
However, holders of depositary shares will be required to pay transfer and other
taxes and government charges, as provided in the deposit agreement.

RESIGNATION AND REMOVAL OF DEPOSITARY

     The depositary may resign at any time by delivering written notice of its
decision to us. We may remove the depositary at any time. Any resignation or
removal will take effect when we appoint a successor depositary. We must appoint
the successor depositary within 60 days after delivery of the notice of
resignation or removal. The successor depositary must be a bank or trust
corporation that has its principal office in the United States and has a
combined capital and surplus of at least $50,000,000.

MISCELLANEOUS

     We will be required to furnish certain information to the holders of the
preferred stock underlying any depositary shares. The depositary, as the holder
of the underlying preferred stock, will forward any report or information it
receives from us to the holders of depositary shares.

     Neither the depositary nor EG&G will be liable if its ability to perform
its obligations under the deposit agreement is prevented or delayed by law or
any circumstance beyond its control. Both EG&G and the depositary will be
obligated to use their best judgment and to act in good faith in performing
their duties under the deposit agreement. Each of EG&G and the depositary will
be liable only for gross negligence and willful misconduct in performing their
duties under the deposit agreement. They will not be obligated to appear in,
prosecute or defend any legal proceeding with respect to any depositary
receipts, depositary shares or preferred stock unless they receive what they, in
their sole discretion, determine to be a satisfactory indemnity from one or more
holders of the depositary shares. EG&G and the depositary will evaluate any
proposed indemnity in order to determine whether the financial protection
afforded by the indemnity is sufficient to reduce each party's risk to a
satisfactory and customary level. EG&G and the depositary may rely on the advice
of legal counsel or accountants of their choice. They may also rely on
information provided by persons they believe, in good faith, to be competent,
and on documents they believe, in good faith, to be genuine.

     The applicable prospectus supplement will identify the depositary's
corporate trust office. Unless the prospectus supplement indicates otherwise,
the depositary will act as transfer agent and registrar for depositary receipts,
and if we redeem shares of preferred stock, the depositary will act as
redemption agent for the corresponding depositary receipts.

TITLE

     EG&G, each depositary and any agent of EG&G or the applicable depositary
may treat the registered owner of any depositary share as the absolute owner of
the depositary shares for all purposes, including making payment, regardless of
whether any payment in respect of such depositary share is overdue and
regardless of any notice to the contrary. See "Book-Entry Securities" below.

                         DESCRIPTION OF DEBT SECURITIES

     The following description, together with the applicable prospectus
supplements, summarizes all the material terms and provisions of the debt
securities that we may offer under this prospectus and the related trust
indentures. The indentures under which debt securities will be issued contain
additional important terms and provisions and are filed as exhibits to the
registration statement which includes this prospectus.

     This summary of the indentures and the debt securities relates to terms and
conditions applicable to the debt securities generally. The particular terms of
any series of debt securities will be summarized in the applicable prospectus
supplement. If indicated in the prospectus supplement, the terms of any series
may differ from the terms summarized below.

GENERAL

     Senior debt securities will be issued under a senior indenture to be
entered into by EG&G and The First National Bank of Chicago, as the senior
trustee. Subordinated debt securities will be issued under a subordinated
indenture to be entered into by EG&G and The First National Bank of Chicago, as
the subordinated trustee.

     We conduct certain of our operations through our subsidiaries. Our rights
and the rights of our creditors, including holders of debt securities, to the
assets of any subsidiary of ours upon that subsidiary's liquidation or
reorganization or otherwise would be subject to the prior claims of that
subsidiary's creditors, except to the extent that we may be a creditor with
recognized claims against the subsidiary. Our subsidiaries' creditors would
include trade creditors, debt holders, secured creditors and taxing authorities.
Neither the debt securities nor the indentures restrict us or any of our
subsidiaries from incurring indebtedness.

     The indentures do not limit the aggregate principal amount of debt
securities we may issue. We may issue debt securities under the indentures from
time to time in one or more series. Unless otherwise specified in a prospectus
supplement:

     - debt securities will be unsecured obligations of EG&G;

     - senior debt securities will rank equally with all other unsecured and
       unsubordinated indebtedness of EG&G; and

     - subordinated debt securities will be subordinate, in right of payment, to
       all senior debt, which is described below under "-- Subordination of
       Subordinated Debt Securities."

     EG&G will maintain an office or agency in the City of New York and at such
other locations as it sees fit, which will be responsible for all payments of
principal of, and premium, if any, and interest on, the debt securities and the
registration of all transfers of debt securities.

     Unless the applicable prospectus supplement otherwise provides, we will
issue debt securities only in fully registered form without coupons and in
denominations of $1,000 or multiples of that amount. As described under
"Book-Entry Securities" below, the debt securities may be issued in the form of
one or more "book-entry securities" that will be deposited with or on behalf of
a depositary. The depositary must be a clearing agent registered under the
Exchange Act. No service charge will be made for any registration of transfer or
exchange of debt securities, but we may require payment of a sum sufficient to
cover any tax or other governmental charge imposed in connection with the
transfer or exchange.

                                      -18-
<PAGE>   22

     The applicable prospectus supplement will describe the following terms of
the debt securities to be offered:

     - the title of the debt securities;

     - any limit on the aggregate principal amount of the debt securities;

     - the person or entity to whom any interest will be payable, if that person
       or entity is not the registered owner of the debt securities;

     - the date or dates on which the principal of and premium, if any, on the
       debt securities is payable or the method of determining such date or
       dates;

     - the rates, which may be fixed or variable, per annum at which the debt
       securities will bear interest, if any, and the date or dates from which
       interest, if any, will accrue;

     - the dates on which interest, if any, on the debt securities will be
       payable, and the regular record dates for interest payment dates or the
       method for determining these dates;

     - the place or places where the principal of, and premium, if any, and
       interest on, the debt securities will be payable;

     - any mandatory or optional sinking fund or similar provisions or
       provisions for mandatory redemption or redemption at the option of the
       holder;

     - the period or periods within which or the date, if any, after which and
       the price or prices at which the debt securities may, in accordance with
       any optional or mandatory redemption provisions, be redeemed and the
       other terms of any such redemption provision;

     - if other than denominations of $1,000 or any multiple of that amount, the
       denominations in which the debt securities will be issuable;

     - if other than the full principal amount of the debt securities, the
       portion of the principal amount of the debt securities which will be
       payable upon the declaration of acceleration of the maturity thereof;

     - the currency of payment of principal of, and premium, if any, and
       interest on, the debt securities;

     - any index, formula or other method used to determine the amount of
       payment of principal of, and premium, if any, and interest on, the debt
       securities;

     - the applicability of the provisions described below under "-- Defeasance
       of Debt Securities or Certain Covenants in Certain Circumstances," and
       the conditions under which these provisions will apply;

     - any additional, modified or different covenants applicable to the debt
       securities;

     - in the case of the subordinated debt securities, the applicability of the
       provisions described below under "-- Conversion or Exchange of Debt
       Securities;"

     - if the debt securities will be issuable only in the form of a global
       security as described below under "Book-Entry Debt Securities," the
       depositary or its nominee for the debt securities and the circumstances
       under which the global security may be registered for transfer or
       exchange in the name of a person other than the depositary or its
       nominee;

     - any event of default with respect to the debt securities of such series,
       in addition to ones set forth in the applicable indenture; and

     - any other terms of the debt securities.

     The debt securities may be offered and sold at a substantial discount below
their stated principal amount. The applicable prospectus supplement will
describe federal income tax consequences and other special considerations
applicable to any such original issue discount debt securities. "Original issue
discount debt securities" means any debt

                                      -19-
<PAGE>   23

security which provides for an amount less than the principal amount of the debt
security to be due and payable upon the declaration of acceleration of the
maturity of the debt security upon the occurrence of an event of default and the
continuation of such event of default.

     We may also offer indexed debt securities under this prospectus. "Indexed
debt securities" are debt securities having a principal amount payable upon
maturity that is more or less than the original principal amount of such debt
securities at the time of issuance.

     If the purchase price of any of the debt securities is payable in one or
more foreign currencies or currency units, any debt securities are denominated
in one or more foreign currencies or currency units, or the principal of, and
premium, if any, or interest, if any, on, any debt securities is payable in one
or more foreign currencies or currency units, then the restrictions, elections,
material U.S. federal income tax considerations and other information with
respect to the debt securities and the foreign currency or currency units will
be described in the applicable prospectus supplement.

     If any index is used to determine the amount of payments of principal of,
or premium, if any, or interest, if any, on, any series of debt securities, then
the material U.S. Federal income tax, accounting and other considerations
applicable to the use of the index will be described in the applicable
prospectus supplement.

SUBORDINATION OF SUBORDINATED
DEBT SECURITIES

     Under the subordinated indenture, the payment of the principal of, premium,
if any, and interest on, and any payments on the repurchase of, subordinated
debt securities will be subordinated in right of payment to all senior debt.

     If EG&G pays or distributes its assets to creditors upon a liquidation,
dissolution, winding up, reorganization, assignment for the benefit of
creditors, marshalling of assets or any bankruptcy, insolvency or similar
proceedings, then the holders of all senior debt will first be entitled to
receive payment in full of all amounts due on the senior debt, or provision will
be made for such payment in cash or cash equivalents in a manner satisfactory to
the holders of senior debt, before the holders of subordinated debt securities
will be entitled to receive any such payment.

     Holders of subordinated debt may, however, receive stock or securities of
EG&G or another corporation in such a bankruptcy or reorganization of the nature
described above if (a) the issuance of the stock or securities is authorized by
the bankruptcy court and (b) the stock or securities are subordinated in right
of payment to all outstanding senior debt to the same extent as the subordinated
debt held by these holders.

     If the maturity of any subordinated debt is accelerated, then the holders
of all senior debt will first be entitled to receive payment in full of all
amounts due on this senior debt, or provision will be made for such payment in
cash or cash equivalents in a manner satisfactory to the holders of senior debt,
before the holders of the subordinated debt securities will be entitled to
receive any such payment.

     No payments on account of principal of, premium, if any, or interest on, or
any repurchase in respect of subordinated debt securities may be made if there
is a default in any payment with respect to senior debt, or an event of default
with respect to any senior debt permitting the holders of such senior debt to
accelerate the maturity of the senior debt.

     "Senior debt" generally means the principal of, and premium, if any, and
unpaid interest on, all present and future indebtedness and obligations of EG&G,
unless the instrument creating or evidencing the indebtedness or obligation
expressly provides that the indebtedness or obligation is not senior to payment
of subordinated debt securities.

     The applicable prospectus supplement may further describe the provisions,
if any, applicable to the subordination of the

                                      -20-
<PAGE>   24

subordinated debt securities of a particular series.

BOOK-ENTRY DEBT SECURITIES

     We may issue any series of debt securities in the form of one or more
global securities. We will deposit these global securities with a depositary or
its nominee identified in the applicable prospectus supplement. In this case, we
will issue one or more global securities in a denomination or aggregate
denominations equal to the portion of the aggregate principal amount of
outstanding debt securities of the series to be represented by the global
security or securities.

     With certain exceptions, unless and until a global security is exchanged in
whole or in part for debt securities in definitive registered form, the global
security may not be registered for transfer or exchange, except as a whole by
the depositary for the global security to a nominee of the depositary and except
in the circumstances described in the applicable prospectus supplement.

     The applicable prospectus supplement will describe the specific terms of
the depositary arrangement for any portion of a series of debt securities to be
represented by a global security. See the discussion below under "Book-Entry
Securities."

CONVERSION OR EXCHANGE OF
DEBT SECURITIES

     The prospectus supplement will set forth the terms, if any, on which a
series of subordinated debt securities may be converted into or exchanged for
other securities of EG&G. These terms will include whether conversion or
exchange is mandatory, or is at our option or the option of the holder. We will
also describe how we will calculate the number of securities that holders of
subordinated debt securities would receive if they were to convert or exchange
their debt securities.

CERTAIN RESTRICTIVE PROVISIONS

  LIMITATION ON LIENS

     The senior indenture contains a covenant that we will not, and will not
permit any of our restricted subsidiaries to, create, issue, assume, incur or
guarantee any secured funded debt without first insuring that the senior debt
securities will be secured equally and ratably with, or senior to, the secured
funded debt. This covenant will not prevent us or any of our restricted
subsidiaries from creating, issuing, assuming, incurring or guaranteeing:

     - secured funded debt that is owed to EG&G or another of our restricted
       subsidiaries;

     - secured funded debt resulting from a lien, pledge or other encumbrance on
       our property or the property of a restricted subsidiary in favor of the

       progress, advance or other payments or performance under any contract or
       statute;

     - secured funded debt that is secured by a lien, pledge or other
       encumbrance on property, shares of stock or indebtedness of any entity at
       the time that the entity becomes a restricted subsidiary;

       property existing on the property at the time of the acquisition or lease
       of the property by EG&G or a restricted subsidiary, or created or

       including any acquisition through merger or consolidation, of the
       property, stock or indebtedness;

     - secured funded debt secured by a lien, pledge or other encumbrance
       incurred or assumed in connection with the issuance of revenue bonds, the
       interest on which is exempt from federal income tax;

       debt existing on the date of issuance of the series of senior debt
       securities;

     - secured funded debt secured by a lien, pledge or other encumbrance on

                                      -21-
<PAGE>   25

       property of an entity which exists at the time that the entity is merged
       or consolidated with EG&G or a restricted subsidiary, or of the sale,
       lease or other disposition of all or substantially all of the properties
       of an entity to EG&G or a restricted subsidiary;

     - secured funded debt incurred to purchase inventory, equipment or other
       property acquired or held by EG&G or a restricted subsidiary that is
       secured by a lien, pledge or other encumbrance on the inventory,
       equipment or property, or to construct or improve any property of EG&G or
       a restricted subsidiary;

     - secured funded debt, if immediately after incurrence or issuance of the
       secured funded debt, the sum of all (a) outstanding secured funded debt
       of EG&G and our restricted subsidiaries incurred as described in this
       subparagraph and (b) attributable debt of EG&G and our restricted
       subsidiaries in respect of sale and leaseback transactions, does not
       exceed 10% of consolidated net tangible assets (the "10% Limit"); and

     - any extension, renewal or replacement of any secured funded debt we are
       permitted to incur in accordance with the terms described above.

     For purposes of this covenant:

     - "restricted subsidiaries" means all subsidiaries of EG&G, other than
       those subsidiaries that our board of directors designates as
       "unrestricted subsidiaries" under the senior indenture, and any
       subsidiary, a majority of the voting stock of which is owned by
       unrestricted subsidiaries;

       (b) guarantees of indebtedness for borrowed money of any other entity
       maturing more than 12 months after the time of computation of the
       indebtedness, except certain guarantees arising in the ordinary course of

       (c) indebtedness for borrowed money maturing more than 12 months after
       the time of computation of the indebtedness which is secured by a lien,

       subsidiary, regardless of whether the indebtedness is assumed by EG&G or
       its restricted subsidiaries.

       Funded debt does not include any amounts relating to obligations under
       leases or lease guarantees, including attributable debt, or any accrued
       liabilities relating to any pension plan or post retirement medical plan,
       regardless of whether any of these obligations would be included as
       liabilities on a consolidated balance sheet of EG&G and its restricted
       subsidiaries;

     - "attributable debt" means, with respect to any sale and leaseback
       transaction:

       (a) the balance sheet liability amount of any capital lease entered into

            accepted accounting principles, less

            (2) any amounts required to be paid in respect of maintenance and
            repairs, insurance, taxes, assessments, water rates and similar

            average cost of funds for borrowed money;

     - "consolidated net tangible assets" means the total amount of assets on a
       consolidated balance sheet of EG&G and its restricted subsidiaries, less
       applicable reserves and other properly deductible items and after
       excluding any investments made in unrestricted subsidiaries, and after
       deducting:

       (a) all liabilities, including all amounts relating to obligations under
       leases or lease guarantees, including any attributable debt, which under
       generally accepted accounting principles would be included on the
       consolidated balance sheet, but not including funded debt, accrued

       plans, capital stock and surplus, surplus reserves and provisions for
       deferred income taxes, and

       principal property or, if later, the completion of construction and
       commencement of full operations of the principal property, to an entity,
       and leases from such entity the principal property. Sales and leaseback
       transactions do not include transactions of this nature between EG&G and
       our restricted subsidiaries or between restricted subsidiaries, or
       involving the taking back of a lease for a period of three years or less;
       and

     - "principal property" means any real property of EG&G or a restricted
       subsidiary, and any equipment located at, or which is a part of, any such
       real property, which has a net book value in excess of the greater of
       $20,000,000 or 5% of consolidated net tangible assets.

  RESTRICTIONS ON SALE AND LEASEBACK TRANSACTIONS

     The senior indenture contains a covenant that we will not, and will not
permit our restricted subsidiaries, to enter into any sale and leaseback
transaction involving any principal property, unless:

     - EG&G or a restricted subsidiary could create secured funded debt on the
       property without exceeding the 10% Limit, in a principal amount at least
       equal to the attributable debt relating to the sale and leaseback
       transaction that is secured by liens, pledges or other encumbrances on
       the property to be leased, without equally and ratably securing the
       outstanding senior debt securities;

     - EG&G, within 120 days after the effective date of the sale and leaseback
       transaction, applies an amount equal to the value of the sale and
       leaseback transaction to either (a) the retirement of its secured funded
       debt or (b) the purchase of other property which is principal property
       having a fair value, as determined by EG&G, at least equal to the value
       of such sale and leaseback transaction; or

     - EG&G or a restricted subsidiary delivers to the trustee for cancellation
       senior debt securities or funded debt in an aggregate principal amount at
       least equal to the value of the sale and leaseback transaction.

     For purposes of this covenant "value" means the greater of (a) the net
proceeds from the sale of the principal property leased in connection with the
sale and leaseback transaction or (b) the fair value, as

                                      -23-
<PAGE>   27

determined by EG&G, of the principal property at the time of the sale and
leaseback transaction.

EVENTS OF DEFAULT

     Any one of these events will constitute an "event of default" under the
indentures with respect to debt securities of any series:

     - failure to pay principal of or any premium on any debt security of that
       series when due;

     - failure to pay any interest on any debt security of that series when due,
       continued for 30 days;

     - failure to deposit any sinking fund payment, when due, in respect of any
       debt security of that series;

     - failure to perform or breach of any other covenants or warranties of EG&G
       in the applicable indenture continued for 90 days after written notice as
       provided in the indenture;

     - a default under any indebtedness for money borrowed by EG&G or any of its
       subsidiaries if:

       (a) the default either:

            (1) results from the failure to pay the principal of any of the
            indebtedness at its stated maturity or

            (2) relates to an obligation other than the obligation to pay the
            principal of the indebtedness at its stated maturity, and results in
            the indebtedness becoming due and payable prior to the date on which
            it would otherwise become due and payable;

       (b) the principal amount of the indebtedness, together with the principal
       amount of any other indebtedness in default for failure to pay principal
       at its stated maturity or the maturity of which has been accelerated,
       equals a total outstanding amount of $25,000,000 or more at any one time;
       and

       (c) the indebtedness is not discharged, or the acceleration is not
       rescinded, within 30 days after written notice as provided in the
       applicable Indenture;

       - events of bankruptcy, insolvency or reorganization of EG&G; and

       - any other event of default provided with respect to debt securities of
         that series.

     If any event of default with respect to the debt securities of any series
at the time outstanding occurs and is continuing, either the trustee or the
holders of at least 25% in aggregate principal amount of the outstanding debt
securities of that series may, by written notice to EG&G, declare the principal
amount or, if the debt securities of that series are original issue discount
debt securities or indexed debt securities, a specified portion of the principal
amount of all the debt securities of that series to be due and payable
immediately. At any time after a declaration of acceleration has been made, but
before a judgment or decree based on acceleration has been obtained, the holders
of a majority in aggregate principal amount of outstanding debt securities of
the series may, under the circumstances described in the indenture, rescind the
acceleration.

     The applicable prospectus supplement relating to any series of debt
securities that are original issue discount debt securities or indexed debt
securities will describe the particular provisions relating to acceleration of
the stated maturity of a portion of the principal amount of this type of series
of debt securities upon the occurrence of an event of default and the
continuation of such event of default.

     Each indenture provides that, subject to the duty of the trustee under the
indenture during default to act with the required standard of care, the trustee
will be under no obligation to exercise any of its rights or powers under the
applicable indenture at the request or direction of any of the holders of debt
securities, unless the holders have offered to the trustee reasonable indemnity.

                                      -24-
<PAGE>   28

Subject to these provisions for the indemnification of the trustee and to other
conditions described in the indentures, the holders of a majority in aggregate
principal amount of the outstanding debt securities of any series will have the
right to direct the time, method and place of conducting any proceeding for any
remedy available to the trustee, or exercising any trust or power conferred on
the trustee, with respect to the debt securities of that series.

     No holder of any series of outstanding debt securities will have any right
to institute any proceeding with respect to the applicable indenture or for any
remedy under the applicable indenture, unless:

     - the holder has previously given to the trustee written notice of a
       continuing event of default with respect to debt securities of that
       series;

     - the holders of at least 25% in aggregate principal amount of the
       outstanding debt securities of the series have made written request to
       the trustee to institute the proceeding;

     - such holder or holders have offered reasonable indemnity to the trustee
       in connection with the request to institute a proceeding;

     - the trustee has failed to institute the proceeding within 60 days after
       receipt of the notice of a continuing event of default, request to
       institute a proceeding and offer of indemnity; and

     - the trustee has not received from the holders of a majority in aggregate
       principal amount of the outstanding debt securities of the series before
       the end of this 60-day period a direction inconsistent with the request
       to institute a proceeding.

However, these limitations do not apply to a suit instituted by a holder of a
debt security for enforcement of payment of the principal of, or premium, if
any, or interest on, a debt security on or after the respective due dates
expressed in the debt security.

     We will be required to furnish to the trustee annually a statement as to
our performance of certain of our obligations under the indentures and as to any
default in our performance.

MODIFICATION AND WAIVER

     EG&G and the respective trustees may make modifications and amendments to
the Indentures without the consent of the holders of any of the debt securities
in order to:

     - evidence the succession of another entity to EG&G and the assumption of
       the covenants and obligations of EG&G under the debt securities and the
       indentures by the successor;

     - add to the covenants of EG&G for the benefit of the holders of all or any
       series of debt securities, or surrender any of EG&G's rights or powers
       under the indentures;

     - add additional events of default with respect to any series of debt
       securities;

     - add to or change any provisions to the extent that may be necessary to
       permit or facilitate the issuance of debt securities in bearer form or to
       facilitate the issuance of book-entry securities;

     - add to, change or eliminate any provision affecting only debt securities
       not yet issued;

     - secure the debt securities;

     - establish the form or terms of debt securities of any series;

     - evidence and provide for successor trustees or add or change any
       provisions as may be necessary to provide for or facilitate the
       appointment of a separate trustee or trustees for specific series of debt
       securities;

     - permit payment in respect of debt securities in bearer form or coupons in
       the United States to the extent allowed by law; and

     - cure any ambiguity, correct or supplement any mistaken or inconsistent
       provisions, or make any other provisions with respect to matters or
       questions arising under the indentures, as long as the action does
                                      -25-
<PAGE>   29

       not materially and adversely affect any holder of debt securities then
       outstanding under the applicable indenture.

     EG&G and the trustee may modify and amend each indenture with the consent
of the holders of not less than a majority in aggregate principal amount of the
outstanding debt securities of each series issued under the applicable indenture
that are adversely affected by the modification or amendments. However, without
the consent of the holders of all debt securities affected by a modification or
amendment, EG&G and the trustee may not modify or amend an indenture to:

     - change the stated maturity of the principal of, or any installment of
       principal of or interest on, any debt security;

     - reduce the principal amount of, or the premium, if any, or interest on,
       any debt security, including in the case of an original issue discount
       debt security the amount payable upon acceleration of the maturity of the
       original issue discount debt security;

     - change the place or currency of payment of principal of, or premium, if
       any, or interest on, any debt security;

     - impair the right to institute suit for the enforcement of any payment on
       any debt security on or at the stated maturity of such debt security, or
       in the case of redemption, on or after the redemption date therefor;

     - adversely affect any right of the holders to require EG&G to repurchase
       debt securities;

     - in the case of subordinated debt securities, adversely affect any right
       to convert such debt securities or modify the subordination provisions in
       a manner adverse to the holders of the debt securities in any material
       respect;

     - reduce the percentage in principal amount of outstanding debt securities
       of any series, the consent of whose holders is required for modification
       or amendment of the applicable indenture or for any waiver provided for
       in the applicable indenture; or

     - modify the provision of the applicable indenture requiring unanimous
       consent of the holders of debt securities under the circumstances
       described above, or modify the percentage vote required to consent to
       waivers of past defaults and restrictive covenants, unless the percentage
       required under the applicable indenture is increased.

     With respect to the senior indenture, the holders of at least a majority in
aggregate principal amount of the outstanding debt securities of any series may,
on behalf of all holders of that series, waive compliance by EG&G with
restrictive provisions concerning:

     - consolidations, mergers and sales of assets;

     - limitations on liens;

     - limitations on sale and leasebacks; and

     - limitations on designation of unrestricted subsidiaries as restricted
       subsidiaries.

     With respect to the subordinated indenture, the holders of at least a
majority in aggregate principal amount of the outstanding debt securities of any
series may, on behalf of all holders of that series, waive compliance by EG&G
with restrictive provisions concerning consolidations, mergers and sales of
assets.

     The holders of a majority in aggregate principal amount of the outstanding
debt securities of any series may, on behalf of all holders of that series,
waive any past default under the applicable indenture, except a default in the
payment of principal, premium or interest and in respect of a covenant or
provision of the applicable indenture that cannot be modified or amended without
the consent of the holder of each outstanding debt security of the series
affected thereby.

CONSOLIDATION, MERGER AND SALE OF ASSETS

     We may not consolidate with or merge into any other entity or transfer all
or
                                      -26-
<PAGE>   30

substantially all of our properties and assets to any other entity, unless:

     - we are the surviving entity in the transaction, or the surviving
       corporation or purchaser of our properties and assets is a corporation,
       partnership or trust organized under the laws of any domestic
       jurisdiction, and the successor or purchaser expressly assumes all of our
       obligations and covenants under the indentures and the debt securities;

     - after giving effect to the transaction, no event of default, and no event
       which, after notice or lapse of time, would become an event of default,
       will have occurred and be continuing; and

     - in the case of senior debt securities only and except in the case of a
       merger or consolidation of EG&G and a restricted subsidiary, either (a)
       the holders of a majority in aggregate principal amount of the
       outstanding debt securities of each series have consented to the
       transaction or (b) immediately after consummation of the transaction,
       EG&G or the successor entity would be permitted to incur at least $1.00
       of secured funded debt, without exceeding the 10% Limit.

DEFEASANCE OF DEBT SECURITIES OR CERTAIN
COVENANTS IN CERTAIN CIRCUMSTANCES

  DEFEASANCE AND DISCHARGE

     Each indenture provides that EG&G, at its option:

     - will be discharged from any and all obligations in respect of the debt
       securities of any series, except for certain obligations to register the
       transfer or exchange of debt securities of the series, replace stolen,
       lost or mutilated debt securities of the series, maintain paying agencies
       and hold moneys for payment in trust, and

     - need not comply with certain restrictive covenants of the indenture,

in each case if we deposit in trust with the trustee money and/or U.S.
government obligations which, through the payment of interest on, and principal
of, such money or obligations in accordance with their terms, will provide money
in an amount sufficient to pay all the principal of, and premium, if any, and
interest on, the debt securities of the series on the dates these payments are
due, which may include one or more redemption dates that we may designate, in
accordance with the terms of the applicable indenture and the debt securities of
such series.

     We may only establish this kind of trust if, among other things:

     - no event of default or event which with the giving of notice or lapse of
       time, or both, would become an event of default under the applicable
       Indenture will have occurred and be continuing on the date of the
       deposit;

     - the deposit will not cause the trustee to have any conflicting interest
       with respect to other securities of EG&G; and

     - we have delivered an opinion of counsel to the effect that the holders of
       the debt securities of the series will not recognize income, gain or loss
       for federal income tax purposes as a result of the deposit or defeasance
       and will be subject to federal income tax in the same manner as if the
       defeasance had not occurred.

  DEFEASANCE OF CERTAIN COVENANTS APPLICABLE TO THE SENIOR DEBT SECURITIES

     The senior indenture provides that the terms of any series of senior debt
securities may provide EG&G with the option to be released from the restrictive
covenants described under "-- Certain Restrictive Provisions." Both the senior
and subordinated indentures provide that the terms of any series of debt
securities may provide EG&G with the option to be released from the restrictive
covenant described under "-- Consolidation, Merger and Sale of Assets."

     In order to exercise these options, we will be required to deposit with the
trustee money and/or U.S. government obligations. This money, together with the
payment of interest
                                      -27-
<PAGE>   31

on and principal of such U.S. government obligations, must provide sufficient
money to pay principal of, premium, if any, and interest on, and any mandatory
sinking fund payments in respect of, the debt securities of the series on the
stated maturity of such payments in accordance with the terms of the applicable
indenture and the debt securities. We will also be required to deliver to the
applicable trustee an opinion of counsel to the effect that the deposit and
related covenant defeasance will not cause the holders of the debt securities of
the series to recognize income, gain or loss for federal income tax purposes.

     In the event EG&G exercises one of these options and the debt securities
are declared due and payable because of the occurrence of any event of default,
the amount of money and U.S. government obligations on deposit with the
applicable trustee will be sufficient to pay amounts due on the debt securities
of the affected series at the time of their stated maturity, but may not be
sufficient to pay amounts due on the debt securities of this series at the time
of the acceleration resulting from the event of default. However, we will remain
liable for these payments.

     The applicable prospectus supplement will state if any defeasance
provisions will apply to the offered debt securities.

TRUSTEES

     The First National Bank of Chicago is the trustee under each of the
indentures. The trustee may resign or be removed with respect to one or more
series of debt securities under the applicable indenture and the successor
trustee may be appointed to act with respect to such series. In the event that
two or more persons are acting as trustee with respect to different series of
debt securities, each trustee will be a trustee of a trust under the related
indenture separate and apart from the trust administered by any other trustee.
If this occurs, any action described in this prospectus to be taken by the
"trustee" may then be taken by each trustee only with respect to the one or more
series of securities for which it is trustee.

                                      -28-

                            DESCRIPTION OF WARRANTS

     The following description, together with the applicable prospectus
supplements, summarizes all the material terms and provisions of the warrants
that we may offer under this prospectus and the related warrant agreements and
warrant certificates. Specific warrant agreements will contain additional
important terms and provisions and will be incorporated by reference as an
exhibit to the registration statement which includes this prospectus.

     This summary of the warrant agreements, the warrants and the warrant
certificates relates to terms and conditions applicable to the warrants
generally. The particular terms of any series of warrants will be summarized in
the applicable prospectus supplement. If indicated in the prospectus supplement,
the terms of any series may differ from the terms summarized below.

GENERAL

     We may issue warrants for the purchase of common stock, preferred stock,
depositary shares and/or debt securities in one or more series. We may issue
warrants independently or together with common stock, preferred stock,
depositary shares and/or debt securities, and they may be attached to or
separate from these securities.

     Each series of warrants will be evidenced by warrant certificates issued
under a separate agreement. EG&G will enter into the warrant agreement with a
warrant agent. Each warrant agent will be a bank that we select which has its
principal office in the United States and a combined capital and surplus of at
least $50,000,000. The applicable prospectus supplement relating to a particular
series of warrants will indicate the name and address of the warrant agent.

     The applicable prospectus supplement will describe the terms of the series
of warrants, including:

     - the offering price;

     - the currency for which the warrants may be purchased;

     - if applicable, the designation and terms of the securities with which the
       warrants are issued and the number of warrants issued with each such
       security or each principal amount of such security;

     - if applicable, the date on and after which the warrants and the related
       securities will be separately transferable;

     - in the case of warrants to purchase debt securities, the principal amount
       of debt securities purchasable upon exercise of one warrant and the price
       at, and currency in which, this principal amount of debt securities may
       be purchased upon such exercise;

     - in the case of warrants to purchase common stock, preferred stock or
       depositary shares, the number of shares of common stock or preferred
       stock or depositary shares, as the case may be, purchasable upon the
       exercise of one warrant and the price at which these shares may be
       purchased upon such exercise;

     - the dates on which the right to exercise the warrants will commence and
       expire;

     - certain federal income tax consequences of holding or exercising the
       warrants;

     - the terms of the securities issuable upon exercise of the warrants; and

     - any other terms of the warrants.

     Warrant certificates may be exchanged for new warrant certificates of
different denominations, presented for registration of transfer, and exercised
at the corporate trust office of the warrant agent or any other office indicated
in the applicable prospectus supplement. If the warrants are not separately
transferrable from the securities with which they were issued, such exchange may
take place only in connection with an exchange of

                                      -29-
<PAGE>   33

the certificates representing the related securities.

     Before exercising their warrants, holders of warrants will not have any of
the rights of holders of the securities purchasable upon such exercise,
including:

     - in the case of warrants to purchase debt securities, the right to receive
       payments of principal of, or premium, if any, or interest on, the debt
       securities purchasable upon exercise or to enforce covenants in the
       applicable indenture; or

     - in the case of warrants to purchase common stock, preferred stock or
       depositary shares, the right to receive dividends, if any, or payments
       upon the liquidation, dissolution or winding up of EG&G or to exercise
       voting rights, if any.

EXERCISE OF WARRANTS

     Each warrant will entitle the holder to purchase the securities specified
in the applicable prospectus supplement at the exercise price described in the
applicable prospectus supplement. Unless otherwise specified in the applicable
prospectus supplement, warrants may be exercised at any time up to 5:00 P.M. New
York time on the expiration date set forth in the applicable prospectus
supplement. After the close of business on the expiration date, unexercised
warrants will become void.

     Warrants may be exercised by delivery of the warrant certificate
representing the warrants to be exercised together with certain information, and
payment to the warrant agent in immediately available funds, as provided in the
applicable prospectus supplement, of the required amount. The information
required to be delivered to the warrant agent will be set forth on the reverse
side of the warrant certificate and in the applicable prospectus supplement.

     Upon receipt of the required payment and the warrant certificate properly
completed and duly executed at the corporate trust office of the warrant agent
or any other office indicated in the applicable prospectus supplement, we will
issue and deliver the securities purchasable upon such exercise. If fewer than
all of the warrants represented by the warrant certificate are exercised, a new
warrant certificate will be issued for the remaining amount of warrants. If so
indicated in the applicable prospectus supplement, securities may be surrendered
as all or part of the exercise price for warrants.

ANTIDILUTION PROVISIONS

     In the case of warrants to purchase common stock, the exercise price
payable and the number of shares of common stock purchasable upon the exercise
of each warrant will be subject to adjustment in certain events. No fractional
shares will be issued upon exercise of warrants, but we will pay cash value of
any fractional shares otherwise issuable.

MODIFICATION

     Any warrant agreement and the terms of the related warrants may be amended
by EG&G and the applicable warrant agent by executing a supplemental warrant
agreement, without the consent of the holders of any such warrants, for the
following purposes:

     - curing any ambiguity, or correcting any defective or inconsistent
       provision contained therein, or making any other provisions with respect
       to matters or questions arising under the warrant agreement that is not
       inconsistent with the provisions of the warrant agreement or the warrant
       certificates;

     - evidencing the assumption by any successor to EG&G of the covenants of
       EG&G contained in the warrant agreement and the warrants;

     - appointing a successor warrant agent;

     - evidencing the appointment of a successor warrant agent;

     - adding to the covenants of EG&G for the benefit of the holders of the
       warrants or surrendering any right or power conferred upon EG&G under the
       warrant agreement;
                                      -30-
<PAGE>   34

     - issuing warrants in definitive form, if the warrants are initially issued
       in the form of global securities; or

     - amending the warrant agreement and the warrants in any manner that we may
       deem to be necessary or desirable and that will not adversely affect the
       interests of the holders of the warrants in any material respect.

     EG&G and the warrant agent may also amend any warrant agreement and the
terms of the related warrants by executing a supplemental warrant agreement with
the consent of the holders of not less than a majority in number of the
unexercised warrants affected by the amendment, except that without the consent
of the affected holder, no such amendment may:

     - change the number or amount of securities purchasable upon exercise of
       the warrants so as to reduce the number or amount of securities
       purchasable upon such exercise;

     - shorten the period of time during which the warrants may be exercised;

     - otherwise adversely affect the exercise rights of the holders of the
       warrants in any material respect; or

     - reduce the number of unexercised warrants the consent of holders of which
       is required for amendment of the warrant agreement or the related
       warrants.

CONSOLIDATION, MERGER AND SALE
OF ASSETS

     Each warrant agreement will provide that we may consolidate or merge with
or into any other corporation or sell, lease or transfer all or substantially
all of our assets to any other corporation, provided that:

     - we are the continuing corporation, or the corporation, if other than
       EG&G, that is formed by or results from any such consolidation or merger
       or receives such assets

       (a) is a corporation organized under the laws of the United States of
       America or a U.S. state and

       (b) assumes all of the obligations of EG&G with respect to all the
       unexercised warrants and the applicable warrant agreements; and

     - EG&G or the successor corporation, as the case may be, is not immediately
       in default under such warrant agreement.

ENFORCEABILITY OF RIGHTS BY HOLDERS
OF WARRANTS

     Each warrant agent will act solely as our agent under the applicable
warrant agreement and will not assume any obligation or relationship of agency
or trust with any holder of any warrant. A single bank or trust company may act
as warrant agent for more than one issue of warrants. A warrant agent will have
no duty or responsibility in case of any default by EG&G under the applicable
warrant agreement or warrant including, without limitation, any duty or
responsibility to initiate any proceedings at law or otherwise, or to make any
demand upon EG&G. Any holder of a warrant may, without the consent of the
related warrant agent or the holder of any other warrant, enforce by appropriate
legal action its right to exercise, and receive the securities purchasable upon
exercise of, its warrants.

RESIGNATION AND APPOINTMENT
OF WARRANT AGENT

     We will provide a warrant agent until all the warrants issued have been
exercised or expired in accordance with their terms. The warrant agent may
resign at any time by giving notice to us, and we may at any time remove a
warrant agent. Any such resignation or removal will take effect upon the
appointment of a successor warrant agent. The warrant agent and any successor
warrant agent will be a bank or trust company having its office or agent's
office in the United States and having a combined capital and surplus of at
least $50,000,000.

                                      -31-
<PAGE>   35

TITLE

     EG&G, the warrant agents and any agent of EG&G or the applicable warrant
agent may treat the registered holder of any warrant certificate as the absolute
owner of the warrants for any purpose and as the person entitled to exercise the
rights attaching to the warrants, in each case regardless of any notice to the
contrary.

        DESCRIPTION OF STOCK PURCHASE CONTRACTS AND STOCK PURCHASE UNITS

     The following description, together with the applicable prospectus
supplements, summarizes all the material terms and provisions of the stock
purchase contracts and stock purchase units that we may offer pursuant to this
prospectus. Specific forms of the stock purchase contracts and stock purchase
units and any related collateral arrangements, depositary arrangements, prepaid
securities and the documents under which these securities are issued, contain
additional important terms and provisions and will be incorporated by reference
into the registration statement which includes this prospectus before we issue
any stock purchase contracts.

     We may issue stock purchase contracts that obligate the holders to purchase
from EG&G, and EG&G to sell to the holders, a specified number of shares of
common stock, preferred stock or depositary shares at a future date.

     The price per share of common stock, preferred stock or depositary shares
may be fixed at the time the stock purchase contracts are issued or may be
determined by a specific formula set forth in the stock purchase contracts. The
stock purchase contracts may be issued separately or as a part of stock purchase
units consisting of a stock purchase contract and either debt securities or debt
obligations of third parties, including U.S. Treasury securities, in each case
securing the holder's obligations to purchase the common stock, preferred stock
or depositary shares under the stock purchase contracts.

     The stock purchase contracts may require us to make periodic payments to
the holders of the stock purchase units or vice versa, and these payments may be
unsecured or prefunded on some basis. The stock purchase contracts may require
holders to secure their obligations under the stock purchase contracts in a
specified manner. In certain circumstances we may deliver newly issued prepaid
stock purchase contracts upon release to a holder of any collateral securing the
holder's obligations under the original stock purchase contract.

                             BOOK-ENTRY SECURITIES

     Unless otherwise specified in the applicable prospectus supplement, we will
issue securities, other than common stock, in the form of one or more book-entry
certificates registered in the name of a depositary or a nominee of a
depositary. Unless otherwise specified in the applicable prospectus supplement,
the depositary will be The Depository Trust Company. We have been informed by
DTC that its nominee will be Cede & Co. Accordingly, Cede is expected to be the
initial registered holder of all securities that are issued in book-entry form.

     No person that acquires a beneficial interest in securities issued in
book-entry form will be entitled to receive a certificate representing those
securities, except as set forth in this prospectus or in the applicable
prospectus supplement. Unless and until definitive securities are issued under
the limited circumstances described below, all references to actions by
beneficial owners of securities issued in book-entry form will refer to actions
taken by DTC upon instructions from its participants, and all references to
payments and notices to beneficial owners will refer to payments and notices to
DTC or Cede, as the registered holder of such securities.

     DTC has informed us that it is:

     - a limited purpose trust company organized under New York banking laws;

     - a "banking organization" within the meaning of the New York banking laws;

     - a member of the Federal Reserve System; and

     - a "clearing agency" registered under the Exchange Act.

     DTC has also informed us that it was created to:

     - hold securities for its participating clients, or "participants"; and
                                      -33-
<PAGE>   37

     - facilitate the clearance and settlement of securities transactions among
       participants through electronic book-entry, thereby eliminating the need
       for the physical movement of securities certificates.

     Participants include securities brokers and dealers, banks, trust companies
and clearing corporations. Indirect access to the DTC system also is available
to other indirect participants such as banks, brokers, dealers and trust
companies that clear through or maintain a custodial relationship with a
participant, either directly or indirectly.

     Persons that are not participants or indirect participants but desire to
buy, sell or otherwise transfer ownership of or interests in securities may do
so only through participants and indirect participants. Under the book-entry
system, beneficial owners may experience some delay in receiving payments, as
payments will be forwarded by our agent to Cede, as nominee for DTC. DTC will
forward these payments to its participants, which thereafter will forward them
to indirect participants or beneficial owners. Beneficial owners will not be
recognized by the applicable registrar, transfer agent, trustee, depositary or
warrant agent as registered holders of the securities entitled to the benefits
of the certificate or the applicable indenture, deposit agreement, warrant
agreement, stock purchase contract or stock purchase unit. Beneficial owners
that are not participants will be permitted to exercise their rights as an owner
only indirectly through participants and, if applicable, indirect participants.

     Under the current rules and regulations affecting DTC, DTC will be required
to make book-entry transfers of securities among participants and to receive and
transmit payments to participants. Participants and indirect participants with
which beneficial owners of securities have accounts are also required by these
rules to make book-entry transfers and receive and transmit such payments on
behalf of their respective account holders.

     Because DTC can act only on behalf of participants, who in turn act only on
behalf of other participants or indirect participants, and on behalf of certain
banks, trust companies and other persons approved by it, the ability of a
beneficial owner of securities issued in book-entry form to pledge those
securities to persons or entities that do not participate in the DTC system may
be limited due to the unavailability of physical certificates for the
securities.

     DTC has advised us that it will take any action permitted to be taken by a
registered holder of any securities under the certificate or the applicable
indenture, deposit agreement, warrant agreement, stock purchase contract or
stock purchase unit only at the direction of one or more participants to whose
accounts with DTC the securities are credited.

     Unless otherwise specified in the applicable prospectus supplement, a book-
entry security will be exchangeable for definitive securities registered in the
names of persons other than DTC or its nominee only if:

     - DTC notifies us that it is unwilling or unable to continue as depositary
       for the book-entry security or DTC ceases to be a clearing agency
       registered under the Exchange Act at a time when DTC is required to be so
       registered;

     - we execute and deliver to the applicable registrar, transfer agent,
       trustee, depositary and/or warrant agent an order complying with the
       requirements of the certificate or the applicable indenture, deposit
       agreement, warrant agreement, stock purchase contract and/or stock
       purchase unit that the book-entry security will be so exchangeable; or

     - there is a default in the payment of any amount due in respect of the
       securities or, in the case of debt securities, an event of default with
       respect to the debt securities.

Any book-entry security that is exchangeable in accordance with the preceding
sentence will be exchangeable for securities registered in such names as DTC
directs.

     If one of the events described in the immediately preceding paragraph
occurs,
                                      -34-
<PAGE>   38

DTC is generally required to notify all participants of the availability through
DTC of definitive securities. Upon surrender by DTC of the book-entry security
representing the securities and delivery of instructions for re-registration,
the registrar, transfer agent, trustee, depositary or warrant agent, as the case
may be, will reissue the securities as definitive securities. After reissuance
of the securities, such persons will recognize the beneficial owners of such
definitive securities as registered holders of securities.

     Except as described above:

     - a book-entry security may not be transferred except as a whole book-
       entry security by or among DTC, a nominee of DTC and/or a successor
       depositary appointed by us; and

     - DTC may not sell, assign or otherwise transfer any beneficial interest in
       a book-entry security unless the beneficial interest is in an amount
       equal to an authorized denomination for the securities evidenced by the
       book-entry security.

     None of EG&G, the trustees, any registrar and transfer agent, any warrant
agent or any depositary, or any agent of any of them, will have any
responsibility or liability for any aspect of DTC's or any participant's records
relating to, or for payments made on account of, beneficial interests in a
book-entry security.

                              PLAN OF DISTRIBUTION

     We may sell the securities through agents, underwriters or dealers, or
directly to one or more purchasers. Goldman, Sachs & Co. and Merrill Lynch,
Pierce, Fenner & Smith Incorporated may be among these agents or underwriters.
In the ordinary course of their businesses, Goldman, Sachs & Co. and Merrill
Lynch, Pierce, Fenner & Smith Incorporated and their respective affiliates have
engaged, and may in the future engage, in commercial banking and/or investment
banking transactions with EG&G or its affiliates.

AGENTS

     We may designate agents who agree to use their reasonable efforts to
solicit purchases for the period of their appointment or to sell securities on a
continuing basis.

UNDERWRITERS

     If we use underwriters for a sale of securities, the underwriters will
acquire the securities for their own account. The underwriters may resell the
securities in one or more transactions, including negotiated transactions, at a
fixed public offering price or at varying prices determined at the time of sale.
The obligations of the underwriters to purchase the securities will be subject
to the conditions set forth in the applicable underwriting agreement. The
underwriters will be obligated to purchase all the securities of the series
offered if any of the securities of that series are purchased. Any initial
public offering price and any discounts or concessions allowed or re-allowed or
paid to dealers may be changed from time to time.

DIRECT SALES

     We may also sell securities directly to one or more purchasers without
using underwriters or agents.

     Underwriters, dealers and agents that participate in the distribution of
the securities may be underwriters as defined in the Securities Act and any
discounts or commissions they receive from us and any profit on their resale of
the securities may be treated as underwriting discounts and commissions under
the Securities Act. The applicable prospectus supplement will identify any
underwriters, dealers or agents and will describe their compensation. We may
have agreements with the underwriters, dealers and agents to indemnify them
against certain civil liabilities, including liabilities under the Securities
Act. Underwriters, dealers and agents may engage in transactions with or

                                      -35-
<PAGE>   39

perform services for us or our subsidiaries in the ordinary course of their
businesses.

TRADING MARKETS AND LISTING OF SECURITIES

     Unless otherwise specified in the applicable prospectus supplement, each
class or series of securities will be a new issue with no established trading
market, other than the common stock, which is listed on the NYSE. We may elect
to list any other class or series of securities on any exchange, but we are not
obligated to do so. It is possible that one or more underwriters may make a
market in a class or series of securities, but the underwriters will not be
obligated to do so and may discontinue any market making at any time without
notice. We cannot give any assurance as to the liquidity of the trading market
for any of the securities.

STABILIZATION ACTIVITIES

     Any underwriter may engage in over-allotment, stabilizing transactions,
short covering transactions and penalty bids in accordance with Regulation M
under the Exchange Act. Over-allotment involves sales in excess of the offering
size, which create a short position. Stabilizing transactions permit bids to
purchase the underlying security so long as the stabilizing bids do not exceed a
specified maximum. Short covering transactions involve purchases of the
securities in the open market after the distribution is completed to cover short
positions. Penalty bids permit the underwriters to reclaim a selling concession
from a dealer when the securities originally sold by the dealer are purchased in
a covering transaction to cover short positions. Those activities may cause the
price of the securities to be higher than it would otherwise be. If commenced,
the underwriters may discontinue any of the activities at any time.

                             VALIDITY OF SECURITIES

     The legality of the securities have been passed upon for EG&G by Murray
Gross, Esq. At the time of this opinion, Mr. Gross was the Senior Vice
President, General Counsel and Clerk of EG&G. As of May 2, 1999, Murray Gross,
Esq. beneficially owned 175,844 shares (including options to purchase 143,000
shares) of common stock of EG&G. In addition, other customary legal matters
relating to the offering of the securities, including matters relating to our
due incorporation, legal existence and authorized capitalization, will be passed
upon for EG&G by its General Counsel or Hale and Dorr LLP, Boston,
Massachusetts.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 67, Chapter 156B of the General Laws of the Commonwealth of
Massachusetts, as amended (the "Massachusetts Business Corporation Law"), and
Article V, Section 9 of the Registrant's Bylaws, to which reference is hereby
made, contain provisions authorizing indemnification by the Registrant of
directors, officers, employees or agents against certain liabilities and
expenses, which they may incur as directors, officers, employees or agents of
the Registrant or of certain other entities. Section 67, Chapter 156B of the
Massachusetts Business Corporation Law provides that the indemnification of
directors, officers, employees and agents of a corporation and persons who serve
at the corporation's request as directors, officers, employees and other agents
of another organization may be provided to whatever extent as shall be specified
by (i) the articles of organization of the corporation or (ii) a bylaw adopted
by the stockholder or (iii) a vote adopted by the holders of a majority of the
shares of stock entitled to vote on the election of directors. Unless otherwise
provided in the articles of organization or the bylaws, the indemnification of
any persons described above who are not directors of the corporation may be
provided by the corporation to the extent authorized by the directors. Such
indemnification may include payment by the corporation of expenses incurred in
defending a civil or criminal action or proceeding prior to the final
disposition of such action or proceeding, upon receipt of an undertaking by the
indemnified person to repay such payment if he shall be adjudicated to be not
entitled to indemnification under Section 67, Chapter 156B of the Massachusetts
Business Corporation Law. Any indemnification may be provided although the
person to be indemnified is no longer an officer, director, employee or agent of
the corporation or of such other organization. Indemnification may not be
provided for any person with respect to any matter as to which that person shall
have been adjudicated in any proceeding to not have acted in good faith in the
reasonable belief that his action was in the best interest of the corporation.

     Section 65, Chapter 156B of the Massachusetts Business Corporation Law
provides a limitation on the imposition of liability under other sections of the
Massachusetts Business Corporation Law. Under this Section, a director, officer
or incorporator of a corporation is to perform his duties in good faith and in a
manner he reasonably believes to be in the best interests of the corporation and
with such care as an ordinarily prudent person in a like position would use
under similar circumstances. Such director, officer or incorporator is entitled
to rely on information, opinions, reports or records, including financial
statements, books of accounts and

                                      II-1
<PAGE>   41

other financial records, which are prepared by or presented by or under the
supervision of (i) one or more officers or employees of the corporation whom the
director, officer or incorporator reasonably believes to be reliable and
competent in the matters presented, or (ii) counsel, public accountants or other
persons as to matters that the director, officer or incorporator reasonably
believes to be within such a person's professional expert competence, or (iii)
in the case of a director, a duly constituted committee of the Board of
Directors upon which he does not serve, as to matters within its delegated
authority, which committee the director reasonably believes to merit confidence.
If a director, officer or incorporator performs his duties in the manner that is
set forth above, that fact shall be an absolute defense to any claim asserted
against him except as expressly provided by statute.

     Section 13, Chapter 156B of the Massachusetts Business Corporation Law
provides that the articles of organization of a corporation may contain a
provision eliminating or limiting the personal liability of a director to the
corporation or its stockholders for monetary damages for breach of a fiduciary
duty as a director notwithstanding any provision of law imposing such liability;
provided, however, 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 Sections 61 or 62, Chapter 156B of the Massachusetts Business
Corporation Law, or (iv) for any transaction from which the director derived an
improper personal benefit. Article Six of the Restated Articles of Organization
of the Registrant contains a provision consistent with Section 13, Chapter 156B
of the Massachusetts Business Corporation Law and provides that to the fullest
extent permitted by the Massachusetts Business Corporation Law, a director of
the Registrant shall not be personally liable to the Registrant or its
stockholder for monetary damages for breach of fiduciary duty as a director,
notwithstanding any provision of law imposing such liability.

     Section 9 of Article V of the Bylaws of the Registrant contains provisions
relating to the indemnification of directors and officers of the Registrant,
which are consistent with Section 67, Chapter 156B of the Massachusetts Business
Corporation Law. This Section provides that no indemnification will be provided
to any person who was or is a director or officer with respect to any matter as
to which such person shall have been finally adjudicated in any proceeding not
to have acted in good faith in the reasonable belief that his action was in the
best interest of the corporation; nor shall indemnification be provided where
the corporation is required or has undertaken to submit to a court the question
of whether or not indemnification by it is against public policy and it has been
finally determined that such indemnification is against public policy; provided,
however, that, prior to such final adjudication, the corporation may compromise
and settle any such claims and liabilities and pay such expenses, if such
settlement or payment, or both, appears, in the judgment of a majority of those
members of the Board of Directors who are not directly involved in such matters,
to be for the best interest of the corporation as evidenced by a resolution to
that effect adopted after receipt by the corporation of a written opinion of
counsel for the corporation that, based upon the facts available to such counsel
such person has not acted in a manner that would prohibit indemnification.

     Section 67, Chapter 156B of the Massachusetts Business Corporation Law also
contains provisions authorizing a corporation to obtain insurance on behalf of
any director, officer, employee or agent of the corporation against liabilities,
whether or not the corporation would have the power to indemnify against such
liabilities. The Registrant maintains directors' and officers' liability and
company reimbursement liability insurance. Subject to certain deductibles, such
insurance will pay up to $50,000,000 per year on claims or errors and omissions
against the Registrant's directors and officers and will reimburse the
Registrant for amounts paid to indemnify directors and officers against the
costs of such claims pursuant to the Registrant's Bylaws.

                                      II-2
<PAGE>   42

     In the Underwriting Agreements the underwriters will agree to indemnify,
under certain conditions, the Registrant, its directors, certain of its officers
and persons who control the Registrant within the meaning of the Securities Act
of 1933, as amended, against certain liabilities.

ITEM 17.  UNDERTAKINGS

     1.  The undersigned Registrant hereby undertakes:

     (a) 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, as amended;

        (ii) To reflect in the prospectus any facts arising after the effective
        date of the Registration Statement (or the most recent post-effective
        amendment thereof) which, individually or in the aggregate, represent a
        fundamental change in the information set forth in the Registration
        Statement. Notwithstanding the foregoing, any increase or decrease in
        the volume of securities offered (if the total dollar value of
        securities offered

                                      II-3
<PAGE>   43

        would not exceed that which was registered) and any deviation from the
        low or high and of the estimated maximum offering range may be reflected
        in the form of prospectus filed with the Commission pursuant to Rule
        424(b) if, in the aggregate, the changes in volume and price represent
        no more than 20% change in the maximum aggregate offering price set
        forth in the "Calculations of Registration Fee" table in the effective
        Registration Statement; and

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

           Provided, however, that paragraphs (a)(i) and (a)(ii) do not apply if
           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 15(d) of the Securities Exchange
           Act of 1934, as amended, that are incorporated by reference in the
           Registration Statement;

     (b) That, for the purpose of determining any liability under the Securities
     Act of 1933, as amended, 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

     (c) 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.

     2.  The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, as amended, each
filing of the Registrant's annual report pursuant to Section 13(a) or 15(d) of
the Securities Exchange Act of 1934, as amended, (and, where applicable, each
filing of an employee benefit plan's annual report pursuant to Section 15(d) of
the Securities Exchange Act of 1934, as amended) that is incorporated by
reference in the Registration Statement 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.

     3.  Insofar as indemnification for liabilities arising under the Securities
Act of 1933, as amended, may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the provisions described under Item 15
above, 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 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 against the Registrant 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

                COMPUTATION OF RATIO OF EARNINGS TO FIXED CHARGES

     The ratios of earnings to fixed charges are computed by dividing income
from continuing operations before income taxes and fixed charges, as adjusted
for certain equity method investments, by fixed charges. Fixed charges consist
of interest on all indebtedness, including capital lease obligations,
amortization of debt expenses and a percentage of rental expense of operating
leases that represents interest. Our consolidated ratios of earnings to fixed
charges for each of the periods indicated are as follows:
