                          DESCRIPTION OF CAPITAL STOCK
 
     This summary of our Common Stock and Preferred Stock is not complete and is
qualified by reference to all the provisions of our Restated Articles of
Organization, our Bylaws, our Rights Plan (which is summarized below) and the
Massachusetts General Laws. Our Restated Articles of Organization, Bylaws and
Rights Plan are incorporated by reference into the Registration Statement of
which this Prospectus is a part.
 
     This summary of our Common Stock and Preferred Stock, and certain
provisions of our Restated Articles of Organization, Bylaws and Rights Plan and
the Massachusetts General Laws relates to certain terms and conditions
applicable to the Common Stock and Preferred Stock generally. The particular
terms of any series of these Securities will be summarized in the applicable
Prospectus Supplement. If indicated in the Prospectus Supplement, the terms of
any such series may differ from the terms summarized below.
 
     Under our Restated Articles of Organization, 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 January 20, 1999, EG&G had 44,871,331 shares of Common Stock issued
and outstanding. Each outstanding share of Common Stock currently has attached
to it one preferred share purchase right issued pursuant to our 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 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 Restated Articles of Organization 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
 
                                       -6-
<PAGE>   9
 
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 January 20, 1999, no shares of Preferred Stock were outstanding. Our
Restated Articles of Organization authorize our Board 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 such series. 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 had designated 70,000 shares
of the Preferred Stock as "Series C Junior Participating Preferred Stock" in
connection with our 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 Rights Plan, which is described below. As of January 20,
1999, there were no shares of Series C Preferred Stock outstanding. This summary
of our Series C Preferred Stock is not complete and is qualified by reference to
our Restated Articles of Organization.
 
     Voting. Each share of Series C Preferred Stock is entitled to 1,000 votes,
subject to adjustment, and except as provided below, 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. 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 in accordance
with this provision will terminate at such time as the dividend arrearage is
fully paid and, in addition, we have paid at least one regular dividend after
the curing of such 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 Restated
Articles of Organization so as to adversely affect the rights of the Series C
Preferred Stock.
 
     Dividends. The Series C Preferred Stock ranks with respect to the payment
of dividends and the distribution of assets junior to all series of all other
classes of Preferred Stock, unless the terms of such other 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. These dividend
amounts are subject to adjustment under certain circumstances. Dividends on the
Series C Preferred Stock are payable quarterly on the first day of March, June,
September and December in each year.
 
     Our Board 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 does not declare a dividend on the Common
Stock during the period between quarterly dividend payment dates, a dividend of
$1.00 per share of Series C Preferred Stock will nevertheless be
 
                                       -7-
<PAGE>   10
 
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 on all such parity Preferred Stocks.
 
The liquidation amounts set forth above are subject to adjustment under certain
circumstances.
 
     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. The consideration amounts set forth above
are subject to adjustment under certain circumstances.
 
     Certain Restrictions. If any quarterly dividends payable on the Series C
Preferred Stock are in arrears, then, until all such 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 such parity
       stocks;
 
     - redeem any stock ranking junior to the Series C Preferred Stock, unless
       we redeem such junior stock by issuing additional shares of stock ranking
       junior to the Series C Preferred Stock; or
 
     - with certain exceptions, redeem any shares of Series C Preferred Stock or
       shares of stock ranking on a parity with the shares of Series C Preferred
       Stock.
 
     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 such 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-thousandth of a
share. Each fractional share of Series C Preferred Stock will have proportionate
voting, dividend, liquidation and other rights as discussed above.
 
  Undesignated Preferred Stock
 
     This summary of the undesignated Preferred Stock relates to certain terms
and conditions that we expect will apply to all series of the Preferred Stock
offered pursuant to this Prospectus. The applicable Prospectus Supplement will
describe the particular terms of any such series of Preferred Stock. If
indicated in the Prospectus Supplement, the
 
                                       -8-
<PAGE>   11
 
terms of any such series may differ from the terms described below.
 
     This summary of the undesignated Preferred Stock is not complete and is
qualified by reference to our Restated Articles of Organization and the
applicable certificate of designations of Preferred Stock. The form of any
certificate of designations will be incorporated by reference as an exhibit into
the Registration Statement of which this Prospectus is a part 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 such
shares will actually trade after the date of issuance.
 
     Although our Board 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 will issue such a
series of Preferred Stock only if it determines that such an 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, even when a
majority of our stockholders believe that such an acquisition would be in their
best interests or 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 certain circumstances.
 
     Voting. Except as described below, each series of Preferred Stock will have
no voting rights. Under Massachusetts law, however, holders of our capital stock
are entitled to vote in certain limited circumstances. If we wish to amend our
Restated Articles of Organization and such 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. In such an instance, 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 such series of Preferred Stock; or
 
     - approve any amendment to our Restated Articles of Organization or
       applicable certificate of designations,

                                       -9-
<PAGE>   12
 
       which would materially and adversely affect such 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 such 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.
 
This voting right will continue until dividends on such 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 such 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 such 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, cash dividends, payable on such dates and at
such rates as are described in the applicable Prospectus Supplement. Dividends
will be cumulative and will accrue from the date set forth 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 contemporaneously declared and paid on such 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 such series of Preferred Stock and other parity
Preferred Stock will be paid ratably among all holders of such series of
Preferred 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 such shares, unless we convert or
       exchange such repurchased or redeemed stock for junior stock; or
 
     - repurchase or redeem any series of Preferred Stock ranking on a parity
       with such offered series of Preferred Stock or pay any monies into a
       sinking fund for the redemption of any such 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 such 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 such series.

                                      -10-
<PAGE>   13
 
     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 such payment to the holders of Common Stock or any
other junior stock, an amount equal to the liquidation preference per share set
forth in the applicable Prospectus Supplement. In addition to such liquidation
preference, holders of such series 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
such Preferred Stock, then the holders of each such series of stock will share
ratably in such 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 set forth in the applicable Prospectus Supplement.
 
     Redemption. The applicable Prospectus Supplement will set forth 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 such
shares to the status of authorized but unissued shares of Preferred Stock.
 
     Other Rights. The applicable Prospectus Supplement will set forth such
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 such series of Preferred Stock 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.
 
RIGHTS PLAN
 
     On January 25, 1995, our Board adopted a stockholder rights plan (the
"Rights Plan"). Under the Rights Plan, each of our common stockholders received
a dividend 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 before attempting a takeover bid and to provide our Board 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.
 
     This description of the Rights Plan is not complete and is qualified by the
provisions of the Rights Plan. A copy of the Rights Agreement is incorporated by
reference into the Registration Statement of which this Prospectus is a part
from our Registration Statement on Form 8-A, as amended, which was filed with
the SEC on February 9, 1995. 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."

<PAGE>   14
 
  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, subject to adjustment.
 
     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 (an "Acquisition Date"); 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
determines is fair to our stockholders and in EG&G's best interests.
 
  Flip Over Event
 
     If at any time after an Acquisition Date, (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
such transaction equal to (1) the exercise price of the Right divided by (2)
one-half of the market price of such 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 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 may exchange the Rights by
providing to the holder one share of our Common Stock or one-thousandth of a
share of our Series C Preferred Stock for each of such 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 the Rights Plan.
 
CERTAIN PROVISIONS OF EG&G'S
BYLAWS AND MASSACHUSETTS LAW
 
  EG&G's Bylaws
 
     EG&G's Bylaws permit our stockholders to call a special meeting of
stockholders only if such stockholders hold at least 40% of the outstanding
capital stock of EG&G entitled to vote at such a special meeting and such
stockholders satisfy certain procedural requirements in connection with their
request to call such a special meeting.
 
  Business Combinations With Interested Stockholders
 
     The Massachusetts General Laws contain certain 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

                                      -12-
<PAGE>   15
 
defined in the Massachusetts General Laws with an "interested stockholder" for a
period of three years after the date of the transaction in which such a person
became an interested stockholder, unless:
 
     - before the date on which such person became an interested stockholder,
       the board of the corporation approved either the business combination or
       the transaction in which such a 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 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 defined as 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 which 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 (each such event, a "Control Share Acquisition") cannot
exercise any voting power with respect to those shares, or any shares acquired
by such person within 90 days before or after such Control Share Acquisition,
unless such voting rights are authorized by the stockholders of the corporation.
 
     The authorization of voting rights requires the affirmative vote of the
holders of a majority of the outstanding voting shares, excluding shares owned
by:
 
     - the person making the Control Share Acquisition;
 
     - any officer of the corporation; and
 
     - any employee who is also a director of the corporation.
 
     There are a number of exceptions from the definition of Control Share
Acquisition, including acquisitions of shares (a) pursuant to a tender offer,
merger or consolidation which is made pursuant to 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
 
     This summary of certain provisions of each Deposit Agreement, the
Depositary Shares and the Depositary Receipts (each as defined below) is not
complete and is qualified by reference to all the provisions of the applicable
Deposit Agreement and Depositary Receipts. Forms of Deposit Agreement and
Depositary Receipt will be incorporated by reference into the Registration
Statement of which this Prospectus is a part before we issue Depositary
Receipts.
 
     This summary of the Depositary Agreement, the Depositary Shares and the
Depositary Receipts relates to certain terms and conditions applicable to such
Securities generally. The particular terms of any series of Depositary Shares
will be summarized in the applicable Prospectus Supplement. If indicated in such
Prospectus Supplement, the terms of any such 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 receipts ("Depositary Receipts")
for these "Depositary Shares," each of which 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. 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 less than all of the
Depositary Shares, the Depositary will select which Depositary Shares to redeem
by lot, or some substantially equivalent method.
 
                                      -14-
<PAGE>   17
 
     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 (which will be
the same date as the record date for the related Preferred Stock) will be
entitled to instruct the Depositary 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.


 
                                      -15-
<PAGE>   18
 
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. 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
such 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
 
     This summary of the Indentures (as defined below) and the Debt Securities
(as defined below) is not complete and is qualified by reference to all the
provisions of the applicable Indenture pursuant to which such Debt Securities
are issued. The forms of Indentures are filed as exhibits to the Registration
Statement of which this Prospectus is a part.
 
     This summary of the Indentures and the Debt Securities relates to certain
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 such series may differ from the terms summarized below.
 
GENERAL
 
     Senior debt securities (the "Senior Debt Securities") will be issued under
an indenture (the "Senior Indenture"), to be entered into by EG&G and The First
National Bank of Chicago, as trustee (the "Senior Trustee"). Subordinated debt
securities (the "Subordinated Debt Securities" and, together with the Senior
Debt Securities, the "Debt Securities") will be issued under an indenture (the
"Subordinated Indenture" and, together with the Senior Indenture, the
"Indentures") to be entered into by EG&G and The First National Bank of Chicago,
as trustee (the "Subordinated Trustee" and, together with the Senior Trustee,
the "Trustees").
 
     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 the Debt Securities only in fully registered form without coupons and in
denominations of $1,000 or multiples of such 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 the 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.


 
                                      -17-
<PAGE>   20
 
     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 such 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
       such interest, if any, will accrue;
 
     - the dates on which such interest, if any, on the Debt Securities will be
       payable, and the regular record dates for such interest payment dates or
       the method for determining such 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 analogous 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, pursuant to 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 such 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 such 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 such provisions will apply;
 
     - any additional, modified or different covenants applicable to the Debt
       Securities;
 
     - in the case of the Subordinated Indenture, 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 with respect to 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


 
                                      -18-
<PAGE>   21
 
Debt Security which provides for an amount less than the principal amount of
such Debt Security to be due and payable upon the declaration of acceleration of
the maturity of such 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 such Debt Securities and such foreign currency or currency units will
be set forth 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 such index will be described in the applicable
Prospectus Supplement.
 
SUBORDINATION OF SUBORDINATED
DEBT SECURITIES
 
     As set forth in 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, which is defined below.
 
     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 such 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 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 such
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 such 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" is defined generally to mean the principal of, and premium,
if any, and unpaid interest on, all present and future indebtedness and
obligations of EG&G, unless in the instrument creating or evidencing such
indebtedness or obligation, it is expressly provided that such 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


 
                                      -19-
<PAGE>   22
 
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 such Global Securities with a depositary or
its nominee identified in the applicable Prospectus Supplement. In such a 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 such 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, such Global
Security may not be registered for transfer or exchange, except as a whole by
the depositary for such Global Security to a nominee of such 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 with respect to 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;

  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 such
       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 such Sale and Leaseback
       Transaction, applies an amount equal to the Value of such 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



                                      -22-
<PAGE>   25
 
       Senior Debt Securities or Funded Debt in an aggregate principal amount at
       least equal to the Value of such 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 pursuant to the Sale and
Leaseback Transaction or (b) the fair value, as 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 ("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) such default either:
 
            (1) results from the failure to pay the principal of any such
            indebtedness at its stated maturity or
 
            (2) relates to an obligation other than the obligation to pay the
            principal of such indebtedness at its stated maturity, and results
            in such indebtedness becoming due and payable prior to the date on
            which it would otherwise become due and payable;
 
       (b) the principal amount of such indebtedness, together with the
       principal amount of any other such 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) such indebtedness is not discharged, or such acceleration is not
       rescinded, within 30 days after written notice as provided in the
       applicable Indenture;
 
            - certain 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
such series may, under certain circumstances, rescind such 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 such series of
Original Issue Discount Debt Securities or Indexed Debt Securities upon the
occurrence of an
 


                                      -23-
<PAGE>   26
 
Event of Default and the continuation of such Event of Default.
 
     Each Indenture provides that, subject to the duty of the Trustee under such
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 such holders have offered to the Trustee reasonable
indemnity. Subject to such provisions for the indemnification of the Trustee and
to certain other conditions, 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 such 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:
 
     - such 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 such series have made written request to
       the Trustee to institute such 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 such a 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 such series before
       the end of such 60-day period a direction inconsistent with such request
       to institute a proceeding.
 
However, such 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, such Debt Security on or after the respective due dates
expressed in such 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 such 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 such 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 such extent as 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
 


                                      -24-
<PAGE>   27
 
       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, provided that any such action
       does 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 two-thirds 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 such 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
       such 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 waiver of compliance with
       certain provisions of the Indenture or for waiver of certain defaults; 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
       certain waivers, unless the percentage required under the applicable
       Indenture is increased.
 
     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 certain restrictive provisions of the
applicable Indenture. 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
such series affected thereby.
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
     We may not consolidate with or merge into any other entity or transfer all
or substantially all of our properties and assets to any other entity, unless:
 
     - we are the surviving entity in such transaction, or the surviving


 
                                      -25-
<PAGE>   28
 
       corporation or purchaser of our properties and assets is a corporation,
       partnership or trust organized under the laws of any domestic
       jurisdiction, and such 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 such
       transaction or (b) immediately after consummation of such 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 such series, replace stolen,
       lost or mutilated Debt Securities of such 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 such series on the dates such 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.
 
     Such a trust may only be established 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 such
       deposit;
 
     - such 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 such series will not recognize income, gain or
       loss for Federal income tax purposes as a result of such deposit or
       defeasance and will be subject to Federal income tax in the same manner
       as if such 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 certain
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 such options, we will be required to deposit with the
Trustee money and/or U.S. government obligations. Such money, together with the
payment of interest 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


 
                                      -26-
<PAGE>   29
 
sinking fund payments in respect of, the Debt Securities of such series on the
stated maturity of such payments in accordance with the terms of the applicable
Indenture and such 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
such 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 of
such series 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 such series at the time of their stated maturity, but may not be
sufficient to pay amounts due on the Debt Securities of such series at the time
of the acceleration resulting from such Event of Default. However, we will
remain liable for such 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 such Trustee will be a Trustee of a trust under the
related Indenture separate and apart from the trust administered by any other
such Trustee. In such event, any action described in this Prospectus to be taken
by the "Trustee" may then be taken by each such Trustee only with respect to the
one or more series of Securities for which it is Trustee.

     - 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

       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 such shares may be
       purchased upon such exercise;
 
     - the date on which the right to exercise the Warrants will commence and
       the date on which such right or rights will expire;
 
     - certain Federal income tax consequences of holding or exercising such
       Warrants;
 
     - the terms of the Securities issuable upon exercise of such Warrants; and
 
     - any other terms of the Warrants.
 
     Warrant Certificates may be exchanged for new Warrant Certificates of

at the corporate trust office of the Warrant Agent or any other office indicated
in the applicable Prospectus Supplement. If the Warrants are not


 
                                      -28-
<PAGE>   31
 
separately transferrable from the Securities with which they were issued, such
exchange may take place only in connection with an exchange of the certificates
representing such 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, such Debt
       Securities purchasable upon such 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 such Prospectus Supplement. After
the close of business on such 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 such 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 such 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 such
       Warrants or surrendering any right or



                                      -29-
<PAGE>   32
 
       power conferred upon EG&G under the Warrant Agreement;
 
     - issuing Warrants in definitive form, if such 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 such 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 such 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
       such 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 such
       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 such 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.

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 description of Stock Purchase Contracts, Stock Purchase Units and/or
Prepaid Securities contained in an applicable Prospectus Supplement will not be
complete and will be qualified by reference to the Stock Purchase Contracts, the
collateral arrangements and depositary arrangements, if applicable, relating to
such Stock Purchase Contracts or Stock Purchase Units and, if applicable, the
Prepaid Securities and the document under which such Prepaid Securities will be
issued. Certain material United States Federal income tax considerations
applicable to the Stock Purchase Units and Stock Purchase Contracts will also be
set forth in the applicable Prospectus Supplement.
 
     Forms of the Stock Purchase Contracts, Stock Purchase Units, collateral
arrangements, if any, depositary arrangements, if any, Prepaid Securities, if
any, and the documents under which Prepaid Securities are issued, if any, will
be incorporated by reference into the Registration Statement of which this
Prospectus is a part.
 
     We may issue stock purchase contracts ("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 units ("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 such 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 ("Prepaid Securities") upon release to a holder of any
collateral securing such 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 (collectively, with respect to each series or type of Securities,
the "Book-Entry Security") 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 ("DTC"). We have
been informed by DTC that its nominee will be Cede & Co. ("Cede"). 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 such Securities (a
"beneficial owner") 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 (as defined below), 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.


 
                                      -32-
<PAGE>   35
 
     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 ("Participants"); and
 
     - 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 others such as banks, brokers, dealers and trust companies that clear through
or maintain a custodial relationship with a Participant, either directly or
indirectly ("Indirect Participants").
 
     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
such payments will be forwarded by our agent to Cede, as nominee for DTC. DTC
will forward such 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 (the "Rules"), 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 the 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 such
Securities to persons or entities that do not participate in the DTC system may
be limited due to the unavailability of physical certificates for such
Securities.
 
     DTC has advised us that DTC 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 such 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 such 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


 
                                      -33-
<PAGE>   36
 
       requirements of the certificate or the applicable Indenture, Deposit
       Agreement, Warrant Agreement, Stock Purchase Contract and/or Stock
       Purchase Unit that such 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 or an
       event of default that, with the giving of notice or lapse of time, or
       both, would constitute an Event of Default with respect to such Debt
       Securities.
 
Any Book-Entry Security that is exchangeable pursuant to 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, 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 such 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 such 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 certain conditions precedent. 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.


 
                                      -34-
<PAGE>   37
 
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 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 will be passed upon for EG&G by Murray
Gross, Esq., Senior Vice President, General Counsel and Clerk of EG&G. In
addition, certain legal matters relating to the offering of the Securities will
be passed upon for EG&G by Hale and Dorr LLP, Boston, Massachusetts. Certain
legal matters will be passed upon for the underwriters or agents, as the case
may be, by Ropes & Gray, Boston, Massachusetts. As of January 20, 1999, Murray
Gross, Esq. beneficially owned 177,244 shares (including options to purchase
144,400 shares) of Common Stock of EG&G.
 
                                    EXPERTS
 
     The consolidated financial statements of EG&G and the related financial
statement schedules, as of December 28, 1997 and December 29, 1996, and for each
of the fiscal years in the three-year period ended December 28, 1997, appearing

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>   39
 
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.

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
 


                                      II-3
<PAGE>   41
 
        decrease in the volume of securities offered (if the total dollar value
        of securities offered would not exceed that which was registered) and
        any deviation from the low or high 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
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.
 
     4.  The undersigned Registrant hereby undertakes that:
 
     (a) For the purpose of determining any liability under the Securities Act
     of 1933, as amended, the information omitted from the form of prospectus
     filed as part of this Registration Statement in reliance upon Rule 430A and
     contained in a form of prospectus filed by the Registrant pursuant to Rule
     424(b)(1) or (4) or 497(h) under the Securities Act, as amended, shall be
     deemed to be part of this Registration Statement as of the time it was
     declared effective; and


                                      II-4
<PAGE>   42
 
     (b) For the purpose of determining any liability under the Securities Act
     of 1933, as amended, each post-effective amendment that contains a form of
     prospectus 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.
 
     5.  The undersigned Registrant hereby undertakes to file an application for
the purpose of determining the eligibility of the trustee to act under
subsection (a) of Section 310 of the Trust Indenture Act in accordance with the
rules and regulations prescribed by the Commission under Section 305(b)(2) of
the Act.

necessary amount has been theretofore deposited with the Trustee or any Paying
Agent (other than the Company) in trust or set aside and segregated in trust by
the Company (if the Company shall act as its own Paying Agent) for the Holders
of such Securities; provided that, if such Securities are to be redeemed, notice
of such redemption has been duly given pursuant to Section 1104 of this
Indenture or provision therefor satisfactory to the Trustee has been made;

              (iii)  Securities, except to the extent provided in Sections 1302

defeasance as provided in Article Thirteen; and

              (iv)   Securities which have been paid pursuant to Section 306 or
in exchange for or in lieu of which other Securities have been authenticated and
delivered pursuant to this Indenture, other than any such Securities in respect
of which there shall have been presented to the Trustee proof satisfactory to it
that such Securities are held by a bona fide purchaser in whose hands such
Securities are valid obligations of the Company;

provided, however, that in determining whether the Holders of the requisite
principal amount of the Outstanding Securities have given, made or taken any
request, demand, authorization, direction, notice, consent, waiver or other
action hereunder, or whether sufficient funds are available for redemption or
for any other purpose, and for the purpose of making the calculations required
by Section 313 of the Trust Indenture Act, (i) the principal amount of an
Original Issue Discount Security that shall be deemed to be Outstanding shall be
the amount of the principal thereof that would be due and payable as of the date
of such determination upon acceleration of the Maturity thereof pursuant to
Section 502, (ii) the principal amount of a Security denominated in one or more
foreign currencies or currency units shall be the U.S. dollar equivalent,
determined in the manner contemplated by Section 301 on the date of original
issuance of such Security, of the principal amount (or, in the case of an
Original Issue Discount Security, the U.S. dollar equivalent on the date of
original issuance of such Security of the amount determined as provided in (i)
above) of such Security, (iii) the principal amount of any Indexed Security that
may be counted in making such determination or calculation and that shall be
deemed to be Outstanding for such purpose shall be equal to the principal face
amount of such Indexed Security at original issuance, unless otherwise provided
with respect to such

any other obligor upon the Securities or any Affiliate of the Company or of such
other obligor shall be disregarded and deemed not to be Outstanding, except
that, in determining whether the Trustee shall be protected in relying upon any
such request, demand, authorization, direction, notice, consent, waiver or other
action, only Securities which a Responsible Officer of the Trustee actually
knows to be so owned shall be so disregarded. Securities so owned which have
been pledged in good faith may be regarded as Outstanding if the pledgee

with respect to such Securities and that the pledgee is not the Company or any
other obligor upon the Securities or any Affiliate of the Company or of such
other obligor.

<PAGE>   17
Trustee such certificates and opinions as may be required under the Trust

Opinion of Counsel, if to be given by counsel, and shall comply with the

condition or covenant provided for in this Indenture shall include:

Section 103. FORM OF DOCUMENTS DELIVERED TO TRUSTEE.

         In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous. Any such certificate or opinion of counsel may be based, insofar as
it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company stating that the

Company, unless such counsel knows, or in the exercise of reasonable care

should know, that the certificate or opinion or representations with respect to
such matters are erroneous.

applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

Section 104. ACTS OF HOLDERS; RECORD DATES.

         (a)   Any request, demand, authorization, direction, notice, consent,
waiver or other action provided or permitted by this Indenture to be given, made
or taken by Holders may be embodied in and evidenced by one or more instruments
of substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to a Responsible Officer of the Trustee and, where it is hereby expressly
required, to the Company. Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"Act" of the Holders signing such instrument or instruments. Proof of execution
of any such instrument or of a writing appointing any such agent shall be
sufficient for any purpose of this Indenture and (subject to Section 601)
conclusive in favor of the Trustee and the Company, if made in the manner
provided in this Section.

         (b)   The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which the Trustee deems sufficient.

         (c)   The Company may, in the circumstances permitted by the Trust
Indenture Act, fix any day as the record date for the purpose of determining the
Holders of Securities of any series entitled to give or take any request,
demand, authorization, direction, notice, consent, waiver or other action, or to
vote on any action, authorized or permitted to be given or taken by Holders of
Securities of such series. If not set by the Company prior to the first
solicitation of a Holder of Securities of such series made by any Person in
respect of any such action, or, in the case of any such vote, prior to such
vote, the record date for any such action or vote shall be the 30th day (or, if
later, the date of the most recent list of Holders required





                                     - 11 -

<PAGE>   19
to be provided pursuant to Section 701) prior to such first solicitation or
vote, as the case may be. With regard to any record date for action to be taken
by the Holders of one or more series of Securities, only the Holders of
Securities of such series on such date (or their duly designated proxies) shall
be entitled to give or take, or vote on, the relevant action.

         (d)   The ownership of Securities shall be proved by the Security
Register.

         (e)   Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Holder of any Security shall bind every future Holder
of the same Security and the Holder of every Security issued upon the
registration of transfer thereof or in exchange therefor or in lieu thereof in
respect of anything done, omitted or suffered to be done by the Trustee or the
Company in reliance thereon, whether or not notation of such action is made upon
such Security.

Section 105. NOTICES, ETC., TO TRUSTEE AND COMPANY.

         Any request, demand, authorization, direction, notice, consent, waiver
or Act of Holders or other document provided or permitted by this Indenture to
be made upon, given or furnished to, or filed with,

              (1)   the Trustee by any Holder or by the Company shall be
         sufficient for every purpose hereunder if made, given, furnished or
         filed in writing to or with a Responsible Officer of the Trustee at its
         Corporate Trust Office, or

              (2)   the Company by the Trustee or by any Holder shall be
         sufficient for every purpose hereunder (unless otherwise herein
         expressly provided) if in writing and mailed, first-class postage
         prepaid, to the Company addressed to it at the address of its principal
         office specified in the first paragraph of this instrument or at any
         other address previously furnished in writing to a Responsible Officer
         of the Trustee by the Company.

Section 106. NOTICE TO HOLDERS; WAIVER.

         Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at his address as it appears in the Security Register, not later
than the latest date (if any), and not earlier than the earliest date (if any),
prescribed for the giving of such notice. In any case where notice to Holders is
given by mail, neither the failure to mail such notice, nor any defect in any
notice so mailed, to any particular Holder shall affect the sufficiency of such
notice with respect to other Holders. Any notice mailed to a Holder in the
manner herein prescribed shall be conclusively deemed to have been




                                     - 12 -

<PAGE>   20
received by such Holder, whether or not such Holder actually receives such
notice. Where this Indenture provides for notice in any manner, such notice may
be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Holders shall be filed with the Trustee, but such
filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

         In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of a Responsible
Officer of the Trustee shall constitute a sufficient notification for every
purpose hereunder.

Section 107. CONFLICT WITH TRUST INDENTURE ACT.

         If any provision hereof limits, qualifies or conflicts with a provision
of the Trust Indenture Act that is required under such Act to be a part of and
govern this Indenture, the latter provision shall control. If any provision of
this Indenture modifies or excludes any provision of the Trust Indenture Act
that may be so modified or excluded, the latter provision shall be deemed to
apply to this Indenture as so modified or to be excluded, as the case may be.

Section 108. EFFECT OF HEADINGS AND TABLE OF CONTENTS.

         The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction hereof.

Section 109. SUCCESSORS AND ASSIGNS.

         All covenants and agreements in this Indenture by the Company shall
bind its successors and assigns, whether so expressed or not.

Section 110. SEPARABILITY CLAUSE.

         In case any provision in this Indenture or in the Securities shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

Section 111. BENEFITS OF INDENTURE.

         Nothing in this Indenture or in the Securities, express or implied,
shall give to any Person, other than the parties hereto and their successors
hereunder and the Holders, any benefit or any legal or equitable right, remedy
or claim under this Indenture.

ACCORDANCE WITH THE LAWS OF THE COMMONWEALTH OF MASSACHUSETTS WITHOUT REGARD TO

Section 113. LEGAL HOLIDAYS.

         In any case where any Interest Payment Date, Redemption Date, Stated
Maturity or Maturity of any Security shall not be a Business Day at any Place of
Payment, then (notwithstanding any other provision of this Indenture or of the
Securities (other than a provision of the Securities of any series which
specifically states that such provision shall apply in lieu of this Section))
payment of interest or principal (and premium, if any) need not be made at such
Place of Payment on such date, but may be made on the next succeeding Business
Day at such Place of Payment with the same force and effect as if made on the
Interest Payment Date, the Redemption Date, or at the Stated Maturity or
Maturity, provided that no interest shall accrue for the period from and after
such Interest Payment Date, Redemption Date, Stated Maturity Date or Maturity,
as the case may be.

         The Securities of each series shall be issuable in registered form

Section 303. EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

         The Securities shall be executed on behalf of the Company by its
Chairman of the Board, its Chief Executive Officer, its President, its Chief
Financial Officer or one of its Vice Presidents, under its corporate seal
reproduced thereon attested by its Clerk or one of its Assistant Clerks. The
signature of any of these officers on the Securities may be manual or facsimile.

         Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with the Company Order shall authenticate and deliver or make available for
delivery such Securities; PROVIDED, HOWEVER, that, in the case of Securities of
a series that are not to be originally issued at one time, the Trustee shall
authenticate and deliver or make available for delivery such Securities from
time to time in accordance with such other



                                      -25-

procedures (including, without limitation, the receipt by the Trustee of oral or
electronic instructions from the Company or its duly authorized agents, promptly
confirmed in writing) acceptable to the Trustee as may be specified by or
pursuant to a Company Order delivered to a Responsible Officer of the Trustee
prior to the time of the first authentication of Securities of such series. If
the form or terms of the Securities of the series have been established in or
pursuant to one or more Board Resolutions as permitted by Sections 201 and 301,
in authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to Section 601) shall be fully protected in
relying upon, an Opinion of Counsel stating,

         (a)   if the form of such Securities has been established by or
pursuant to Board Resolution as permitted by Section 201, that such form has
been established in conformity with the provisions of this Indenture;

         (b)   if the terms of such Securities have been established by or
pursuant to Board Resolution as permitted by Section 301, that such terms have
been established in conformity with the provisions of this Indenture; and

         (c)   that such Securities, when authenticated and delivered by the
Trustee and issued by the Company in the manner and subject to any conditions
specified in such Opinion of Counsel, will constitute valid and legally binding
obligations of the Company enforceable in accordance with their terms, subject
to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and
similar laws of general applicability relating to or affecting creditors' rights
and to general equity principles.

If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

         Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the time
of authentication of each Security of such series if such documents, with
appropriate modifications to cover such future issuances, are delivered at or
prior to the authentication upon original issuance of the first Security of such
series to be issued.

         If the Company shall establish pursuant to Section 301 that the
Securities of a series are to be issued in whole or in part in the form of one
or more Book-Entry



                                      -26-

<PAGE>   34
Securities, then the Company shall execute and the Trustee shall, in accordance
with this Section and the Company Order with respect to such series,
authenticate and deliver or make available for delivery one or more Securities
in such form that (i) shall represent and shall be denominated in an amount
equal to the aggregate principal amount of the Outstanding Securities of such
series to be represented by such Book-Entry Security or Securities, or such
portion thereof as the Company shall specify in a Company Order, (ii) shall be
registered in the name of the Depositary for such Book-Entry Security or
Securities or the nominee of such Depositary, (iii) shall be delivered by the
Trustee to such Depositary or pursuant to such Depositary's instruction and (iv)
shall bear the legend substantially to the effect set forth in Section 204.

         Unless otherwise established pursuant to Section 301, each Depositary
designated pursuant to Section 301 for a Book-Entry Security must, at the time
of its designation and at all times while it serves as Depositary, be a clearing
agency registered under the Securities Exchange Act of 1934 and any other
applicable statute or regulation. The Trustee shall have no responsibility to
determine if the Depositary is so registered. Each Depositary shall enter into
an agreement with the Trustee governing the respective duties and rights of such
Depositary and the Trustee with regard to Book-Entry Securities.

         Unless otherwise provided in the form of Security for any series, each
Security shall be dated the date of its authentication.

         No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder. Notwithstanding the
foregoing, if any Security shall have been authenticated and delivered hereunder
but never issued and sold by the Company, and the Company shall deliver such
Security to the Trustee for cancellation as provided in Section 309, for all
purposes of this Indenture such Security shall be deemed never to have been
authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture.

Section 304. TEMPORARY SECURITIES.

         Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver or make available for delivery, temporary Securities which are printed,
lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the definitive Securities in lieu of
which they are issued and with such appropriate insertions, omissions,
substitutions and other variations as



                                      -27-
<PAGE>   35
the officers executing such Securities may determine, as evidenced by their
execution of such Securities.

         If temporary Securities of any series are issued, the Company will
cause definitive Securities of that series to be prepared without unreasonable
delay. After the preparation of definitive Securities of such series, the
temporary Securities of such series shall be exchangeable for definitive
Securities of such series upon surrender of the temporary Securities of such
series at the office or agency of the Company in a Place of Payment for that
series, without charge to the Holder. Upon surrender for cancellation of any one
or more temporary Securities of any series the Company shall execute and the
Trustee shall authenticate and deliver or make available for delivery in
exchange therefor one or more definitive Securities of the same series, of any
authorized denominations and of a like aggregate principal amount and tenor.
Until so exchanged the temporary Securities of any series shall in all respects
be entitled to the same benefits under this Indenture as definitive Securities
of such series and tenor.

Section 305. REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

         The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the register maintained in such office and in any other
office or agency of the Company in a Place of Payment being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities. The Trustee is hereby
appointed "Security Registrar" for the purpose of registering Securities and
transfers of Securities as herein provided.

         Upon surrender for registration of transfer of any Security of any
series at the office or agency in a Place of Payment for that series, the
Company shall execute, and the Trustee shall authenticate and deliver or make
available for delivery, in the name of the designated transferee or transferees,
one or more new Securities of the same series, of any authorized denominations
and of a like aggregate principal amount and tenor.

         At the option of the Holder, Securities of any series may be exchanged
for other Securities of the same series, of any authorized denominations and of
a like aggregate principal amount and tenor, upon surrender of the Securities to
be exchanged at such office or agency. Whenever any Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver or make available for delivery, the Securities which
the Holder making the exchange is entitled to receive.

         All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled



                                      -28-

<PAGE>   36
to the same benefits under this Indenture, as the Securities surrendered upon
such registration of transfer or exchange.

         Every Security presented or surrendered for registration of transfer or
for exchange shall (if so required by the Company, the Security Registrar or the
Trustee) be duly endorsed, or be accompanied by a written instrument of transfer
in form satisfactory to the Company, the Security Registrar and the Trustee duly
executed, by the Holder thereof or his attorney duly authorized in writing.

         No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.

         The Company shall not be required (i) to issue, register the transfer
of or exchange Securities of any series during a period beginning at the opening
of business 15 days before the day of the mailing of a notice of redemption of
Securities of that series selected for redemption under Section 1103 and ending
at the close of business on the day of such mailing, or (ii) to register the
transfer of or exchange any Security so selected for redemption in whole or in
part, except the unredeemed portion of any Security being redeemed in part.

         Notwithstanding the foregoing, any Book-Entry Security shall be
exchangeable pursuant to this Section 305 for Securities registered in the names
of Persons other than the Depositary for such Security or its nominee only if
(i) such Depositary notifies the Company that it is unwilling or unable to
continue as Depositary for such Book-Entry Security or if at any time such
Depositary ceases to be a clearing agency registered under the Securities
Exchange Act of 1934, as amended, (ii) the Company executes and delivers to the
Trustee a Company Order that such Book-Entry Security shall be so exchangeable
or (iii) there shall have occurred and be continuing an Event of Default with
respect to the Securities. Any Book-Entry Security that is exchangeable pursuant
to the preceding sentence shall be exchangeable for Securities registered in
such names as such Depositary shall direct.

         Notwithstanding any other provision in this Indenture, unless and until
it is exchanged in whole or in part for Securities that are not in the form of a
Book-Entry Security, a Book-Entry Security may not be transferred or exchanged
except as a whole by the Depositary with respect to such Book-Entry Security to
a nominee of such Depositary or by a nominee of such Depositary to such
Depositary or another nominee of such Depositary.

Section 306. MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.



                                      -29-

<PAGE>   37
         If any mutilated Security is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver or make available
for delivery in exchange therefor a new Security of the same series and of like
tenor and principal amount and bearing a number not contemporaneously
outstanding.

         If there shall be delivered to the Company and the Trustee (i) evidence
to their satisfaction of the destruction, loss or theft of any Security and (ii)
such security or indemnity as may be required by them to save each of them and
any agent of either of them harmless, then, in the absence of notice to the
Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute and the Trustee shall authenticate and
deliver, in lieu of any such destroyed, lost or stolen Security, a new Security
of the same series and of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

         In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.

         Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

         Every new Security of any series issued pursuant to this Section in
lieu of any destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities of that series duly issued hereunder.

         The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.

Section 307. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

         Except as otherwise contemplated by Section 301 with respect to any
series of Securities, interest on any Security which is payable, and is
punctually paid or duly provided for, on any Interest Payment Date shall be paid
to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest at the office or agency maintained for such purpose pursuant
to Section 1002; PROVIDED, HOWEVER, that at the option of the Company, interest
on Securities of any series that bear interest may be paid (i) by check mailed
to the address of the Person entitled thereto



                                      -30-

<PAGE>   38
as it shall appear on the Security Register or (ii) by wire transfer to an
account maintained by the Person entitled thereto as specified in the Security
Register.

         Any interest on any Security of any series which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in Clause (1) or (2) below:

              (1)   The Company may elect to make payment of any Defaulted
         Interest to the Persons in whose names the Securities of such series
         (or their respective Predecessor Securities) are registered at the
         close of business on a Special Record Date for the payment of such
         Defaulted Interest, which shall be fixed in the following manner. The
         Company shall notify the Trustee in writing of the amount of Defaulted
         Interest proposed to be paid on each Security of such series and the
         date of the proposed payment, and at the same time the Company shall
         deposit with the Trustee an amount of money equal to the aggregate
         amount proposed to be paid in respect of such Defaulted Interest or
         shall make arrangements satisfactory to the Trustee for such deposit
         prior to the date of the proposed payment, such money when deposited to
         be held in trust for the benefit of the Persons entitled to such
         Defaulted Interest as in this Clause provided. Thereupon the Trustee
         shall fix a Special Record Date for the payment of such Defaulted
         Interest which shall be not more than 15 days and not less than 10 days
         prior to the date of the proposed payment and not less than 10 days
         after the receipt by the Trustee of the notice of the proposed payment.
         The Trustee shall promptly notify the Company of such Special Record
         Date and, in the name and at the expense of the Company, shall cause
         notice of the proposed payment of such Defaulted Interest and the
         Special Record Date therefor to be mailed, first-class postage prepaid,
         to each Holder of Securities of such series at his address as it
         appears in the Security Register, not less than 10 days prior to such
         Special Record Date. Notice of the proposed payment of such Defaulted
         Interest and the Special Record Date therefor having been so mailed,
         such Defaulted Interest shall be paid to the Persons in whose names the
         Securities of such series (or their respective Predecessor Securities)
         are registered at the close of business on such Special Record Date and
         shall no longer be payable pursuant to the following Clause (2).

              (2)   The Company may make payment of any Defaulted Interest on
         the Securities of any series in any other lawful manner not
         inconsistent with the requirements of any securities exchange on which
         such Securities may be listed, and upon such notice as may be required
         by such exchange, if, after notice given by the Company to the Trustee
         of the proposed payment



                                      -31-

<PAGE>   39
         pursuant to this Clause, such manner of payment shall be deemed
         practicable by the Trustee.

         Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

Section 308. PERSONS DEEMED OWNERS.

         Prior to due presentment of a Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment of principal of and any premium
and (subject to Section 307) any interest on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.

Section 309. CANCELLATION.

         All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee.
All Securities so delivered and any Securities surrendered directly to the
Trustee for any such purpose shall be promptly cancelled by the Trustee and such
cancellation shall be noted conspicuously on each such Security. The Company may
at any time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company may have acquired in any
manner whatsoever, and may deliver to the Trustee (or to any other Person for
delivery to the Trustee) for cancellation any Securities previously
authenticated hereunder which the Company has not issued and sold, and all
Securities so delivered shall be promptly cancelled by the Trustee. No
Securities shall be authenticated in lieu of or in exchange for any Securities
cancelled as provided in this Section, except as expressly permitted by this
Indenture. Unless the Company directs otherwise by a Company Order, all
cancelled Securities held by the Trustee may be destroyed, but the Trustee shall
not be obligated to so destroy such Securities, and, if any such cancelled
Security is destroyed, the Trustee shall furnish to the Company a certificate
with respect to such destruction.

Section 310. COMPUTATION OF INTEREST.

         Except as otherwise specified as contemplated by Section 301 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.

Section 311. CUSIP NUMBERS.

         The Company in issuing the Securities may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices
of redemption as a convenience to Holders; PROVIDED that any such notice may
state that no representation is made as to the correctness of such numbers
either as printed on the Securities or as contained in any notice of a
redemption and that reliance may be placed only on the other identification
numbers printed on the Securities, and any such redemption shall not be affected
by any defect in or omission of such CUSIP numbers. The Company will promptly
notify the Trustee of any change in the CUSIP numbers.

Section 401. SATISFACTION AND DISCHARGE OF INDENTURE.

registration of transfer, exchange or replacement of such Securities herein
expressly provided for), and the Trustee, at the expense of the Company, shall
execute proper instruments acknowledging satisfaction and discharge of this
Indenture with respect to such Securities, when

              (1)   either

                    (A)   all such Securities theretofore authenticated and

              destroyed, lost or stolen and which have been replaced or paid as
              provided in Section 306 and (ii) such Securities for whose payment
              money has theretofore been deposited in trust or segregated and

              or discharged from such trust, as provided in Section 1003) have
              been delivered to the Trustee for cancellation; or

              Trustee for cancellation

                          (i)    have become due and payable, or

                          (ii)   will become due and payable at their Stated
                    Maturity within one year, or

                    under arrangements satisfactory to the Trustee for the
                    giving of notice of redemption by the Trustee in the name,
                    and at the expense, of the Company,

         and the Company, in the case of (B)(i), (ii) or (iii) above, has
         deposited or caused to be deposited with the Trustee as trust funds in
         trust for the purpose an amount in the currency or currencies or
         currency unit or units in which such Securities are payable sufficient
         to pay and discharge the entire indebtedness on such Securities not
         theretofore delivered to the Trustee for cancellation, for principal
         and any premium and interest to the date of such deposit (in the case
         of Securities which have become due and payable) or to the Stated
         Maturity or Redemption Date, as the case may be;

              (2)   the Company has paid or caused to be paid all other sums
         payable hereunder by the Company; and

         precedent herein provided for relating to the satisfaction and
         discharge of this Indenture with respect to such Securities have been
         complied with.

         Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 607, the obligations of
the Trustee to any Authenticating Agent under Section 614 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of Clause (1) of
this Section, the obligations of the Trustee under Section 402, Article Six and
the last paragraph of Section 1003 shall survive.

Section 402. APPLICATION OF TRUST MONEY.

applied by it, in accordance with the provisions of the Securities and this
Indenture, to the payment, either directly or through any Paying Agent

Section 501. EVENTS OF DEFAULT.

         "Event of Default", wherever used herein with respect to Securities of
any series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body),
unless such event is either inapplicable to a particular series of Securities or
it is specifically deleted or modified in or pursuant to the supplemental
indenture or Board Resolution creating such series of Securities or in the form
of Security for such series:

         maturity or (2) relates to an obligation other than the obligation to
         pay the principal of such indebtedness

         Securities of that series.

Section 502. ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

         If an Event of Default with respect to Securities of any series at the
time Outstanding occurs and is continuing, then in every such case the Trustee
or the Holders of not less than 25% in principal amount of the Outstanding
Securities of that series may declare the principal amount (or, if any of the
Securities of that series are Original Issue Discount Securities or Indexed
Securities, such portion of the principal amount of such Securities as may be
specified in the terms thereof) of all of the Securities of that series to be
due and payable immediately, by a notice in writing to the Company (and to the
Trustee if given by Holders), and upon any such declaration such principal
amount (or, in the case of Original Issue Discount Securities or Indexed
Securities, such specified amount) shall become immediately due and payable.

         At any time after such a declaration of acceleration with respect to

              (1)   the Company has paid or deposited with the Trustee a sum
         sufficient to pay

                    (A)   all overdue interest on all Securities of that series,

         series, other than the non-payment of the principal of Securities of
         that series which have become due solely by such declaration of

              (1)   default is made in the payment of any interest on any
         Security when such interest becomes due and payable and such default
         continues for a period of 30 days, or

              (2)   default is made in the payment of the principal of (or
         premium, if any, on) any Security at the Maturity thereof,

Securities for principal and any premium and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and premium and on any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

         If an Event of Default with respect to Securities of any series occurs
and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of Securities of such series by
such appropriate judicial proceedings as the Trustee shall deem most effectual
to protect and enforce any such rights, whether for the specific enforcement of
any covenant or agreement in this Indenture or in aid of the exercise of any
power granted herein, or to enforce any other proper remedy.

other obligor upon the Securities), its property or its creditors, the Trustee

otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such
proceeding. In particular, the Trustee

or deliverable on any such claims and to distribute the same; and any custodian,
receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Holder to make such
payments to the Trustee and, in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any
amount due it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 607.

         No provision of this Indenture shall be deemed to authorize the Trustee
to authorize or consent to or accept or adopt on behalf of any Holder any plan
of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding.

         All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto, and
any such proceeding instituted by the Trustee shall be brought in its own name
as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

         Trustee of a continuing Event of Default with respect to the Securities
         of that series;

              (2)   the Holders of not less than 25% in principal amount of the
         Outstanding Securities of that series shall have made written request
         to the Trustee to institute proceedings in respect of such Event of
         Default in its own name as Trustee hereunder;

              (3)   such Holder or Holders have offered to the Trustee

         request and offer of indemnity has failed to institute any such
         proceeding; and

         given to the Trustee before or during such 60-day period by the Holders
         of a majority in principal amount of the Outstanding Securities of that
         series;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other
Holders, or to obtain or to seek to obtain priority or preference over any other
Holders or to enforce any right under this Indenture, except in the manner
herein provided and for the equal and ratable benefit of all Holders.

         If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

         Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Securities in the last paragraph of
Section 306 and as otherwise provided in Section 507, no right or remedy herein
conferred upon or reserved to the Trustee or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

to exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or
an acquiescence therein. Every right and remedy given by this Article or by law
to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.

Securities of any series shall 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
Securities of such series, PROVIDED that

              (1)   such direction shall not be in conflict with any rule of law
         or with this Indenture, and

              (2)   the Trustee may take any other action deemed proper by the
         Trustee which is not inconsistent with such direction.

series and its consequences, except a default

              (1)   in the payment of the principal of or any premium or
         interest on any Security of such series, or

              (2)   in respect of a covenant or provision hereof which under
         Article Nine cannot be modified or amended without the consent of the
         Holder of each Outstanding Security of such series affected.

         Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

Section 514. UNDERTAKING FOR COSTS.

         In any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit to
file an undertaking to pay the costs of such suit, and may assess reasonable
costs, including reasonable counsel fees and expenses, against any such party
litigant, in the manner and to the extent provided in the Trust Indenture Act;
PROVIDED that neither this Section nor the Trust Indenture Act shall be deemed
to authorize any court to require such an undertaking or to make such an
assessment in any suit instituted by the Company, the Trustee or the Holders of
10% aggregate principal amount of the Outstanding Securities of any series.

Section 515. WAIVER OF USURY, STAY OR EXTENSION LAWS.

         The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any usury, stay or extension law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

Indenture shall require the Trustee to expend or risk its own funds or otherwise
incur any financial liability in the performance of any of its duties hereunder,
or in the exercise of any of its rights or powers, if it shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against
such risk or liability is not reasonably assured to it. Whether or not therein
expressly so provided, every provision of this Indenture relating to the conduct
or affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section.

rely upon an Officers' Certificate;

         (d)   the Trustee may consult with counsel of its selection and the

expenses and liabilities which might be incurred by it in compliance with such
request or direction;

authorized or within the discretion or rights or powers conferred upon it by
this Indenture; and

Event of Default unless a Responsible Officer of the Trustee has actual
knowledge thereof or unless written notice of any event which is in fact such a
default is received by the Trustee at the Corporate Trust Office of the Trustee,
and such notice references the Securities and this Indenture.

         The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Company, and neither the Trustee nor any Authenticating Agent assumes any

         faith; and

meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to

combined capital and surplus of at least $50,000,000 and an office in the
Borough of Manhattan, The City of New York at which at any particular time the
Trustee's corporate trust business may be administered. If such Person publishes
reports of condition at least annually, pursuant to law or to the requirements
of any Federal or state supervising or examining authority, then for the
purposes of this Section, the combined capital and surplus of such Person shall
be deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. If at any time the Trustee shall cease to be

<PAGE>   54
         (b)   The Trustee may resign at any time with respect to the Securities
of one or more series by giving written notice thereof to the Company. If the
instrument of acceptance by a successor Trustee required by Section 611 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

         (c)   The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of a majority in principal amount
of the Outstanding Securities of such series, delivered to the Trustee and to
the Company. If the instrument of acceptance by a successor Trustee required by
Section 611 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of removal, the Trustee being removed may petition any
court of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series.

         (d)   If at any time:

              (1)   the Trustee shall fail to comply with Section 608 after
         written request therefor by the Company or by any Holder who has been a
         bona fide Holder of a Security for at least six months, or

              (2)   the Trustee shall cease to be eligible under Section 609 and
         shall fail to resign after written request therefor by the Company or
         by any such Holder, or

              (3)   the Trustee shall become incapable of acting or shall be
         adjudged a bankrupt or insolvent or a receiver of the Trustee or of its
         property shall be appointed or any public officer shall take charge or
         control of the Trustee or of its property or affairs for the purpose of
         rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company by or pursuant to a Board Resolution may
remove the Trustee and appoint a successor Trustee with respect to all
Securities, or (ii) subject to Section 514, any Holder who has been a bona fide
Holder of a Security for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee with respect to all Securities and the appointment of a
successor Trustee or Trustees.

         (e)   If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, with
respect to the Securities of one or more series, the Company, by or pursuant to
a Board Resolution, shall promptly appoint a successor Trustee or Trustees with
respect to the Securities of that or those series (it being understood that any
such successor Trustee may be



                                      -47-

<PAGE>   55
appointed with respect to the Securities of one or more or all of such series
and that at any time there shall be only one Trustee with respect to the
Securities of any particular series) and shall comply with the applicable
requirements of Section 611. If, within one year after such resignation, removal
or incapability, or the occurrence of such vacancy, a successor Trustee with
respect to the Securities of any series shall be appointed by Act of the Holders
of a majority in principal amount of the Outstanding Securities of such series
delivered to the Company and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment in accordance
with the applicable requirements of Section 611, become the successor Trustee
with respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Company. If no successor Trustee with respect
to the Securities of any series shall have been so appointed by the Company or
the Holders and accepted appointment in the manner required by Section 611, any
Holder who has been a bona fide Holder of a Security of such series for at least
six months may, on behalf of himself and all others similarly situated, petition
any court of competent jurisdiction for the appointment of a successor Trustee
with respect to the Securities of such series.

         (f)   The Company shall give notice of each resignation and each

Section 611. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

         (a)   In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on the request
of the Company or the successor Trustee, such retiring Trustee shall, upon
payment of its charges, execute and deliver an instrument transferring to such
successor Trustee all the rights, powers and trusts of the retiring Trustee and
shall duly assign, transfer and deliver to such successor Trustee all property
and money held by such retiring Trustee hereunder.

<PAGE>   56
provisions as shall be necessary or desirable to transfer and confirm to, and to
vest in, each successor Trustee all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series to which
the appointment of such successor Trustee relates, (2) if the retiring Trustee
is not retiring with respect to all Securities, shall contain such provisions as
shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series as to which the retiring Trustee is not retiring shall continue
to be vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of
the Company or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.

         (c)   Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in paragraph (a) and (b) of this Section, as the case may be.

         (d)   No successor Trustee shall accept its appointment unless at the
time of such acceptance such successor Trustee shall be qualified and eligible
under this Article.

Section 612. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

         Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities shall have been authenticated,
but not delivered, by the Trustee then in



                                      -49-
<PAGE>   57
office, any successor by merger, conversion or consolidation to such authenti-
cating Trustee may adopt such authentication and deliver the Securities so
authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities.

Section 613. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

         If and when the Trustee shall be or become a creditor of the Company
(or any other obligor upon the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).

Section 614. APPOINTMENT OF AUTHENTICATING AGENT.

         The Trustee may appoint an Authenticating Agent or Agents with respect
to one or more series of Securities which shall be authorized to act on behalf
of the Trustee to authenticate Securities of such series issued upon original
issue and upon exchange, registration of transfer or partial redemption thereof
or pursuant to Section 306, and Securities so authenticated shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any State thereof
or the District of Columbia, authorized under such laws to act as Authenticating
Agent, and if not an Affiliate of the Trustee, having a combined capital and
surplus of not less than $50,000,000 and subject to supervision or examination
by Federal or state authority. If such Authenticating Agent publishes reports of
condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such Authenticating Agent shall be deemed to be
its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time an Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section, such Authenticating
Agent shall resign immediately in the manner and with the effect specified in
this Section.

         Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to all or substantially all the
corporate agency or corporate trust business of an Authenticating Agent, shall
continue to be an Authenticating Agent, provided such corporation shall be
otherwise eligible under



                                      -50-
<PAGE>   58
this Section, without the execution or filing of any paper or any further act on
the part of the Trustee or the Authenticating Agent.

         An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall mail written notice of
such appointment by first-class mail, postage prepaid, to all Holders of
Securities of the series with respect to which such Authenticating Agent will
serve, as their names and addresses appear in the Security Register. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

         The Trustee agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section, and the
Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 607.

         If an appointment with respect to one or more series is made pursuant
to this Section, the Securities of such series may have endorsed thereon, in
addition to or in lieu of the Trustee's certificate of authentication, an
alternative certificate of authentication in the following form:

         This is one of the Securities of the series designated therein referred
to in the within-mentioned Indenture.

designations; PROVIDED, HOWEVER, that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain an office or agency
in each Place of Payment for Securities of any series for such purposes. The
Company will give prompt written notice to the Trustee of any such designation
or rescission and of any change in the location of any such other office or
agency.

Section 1003. MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST.

         If the Company shall at any time act as its own Paying Agent with
respect to any series of Securities, it will, on or before each due date of the
principal of or any premium or interest on any of the Securities of that series,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay the principal and any premium and interest so becoming due
until such sums shall be paid to such Persons or otherwise disposed of as herein
provided and will promptly notify the Trustee of its action or failure so to
act.

         Whenever the Company shall have one or more Paying Agents for any
series of Securities, it will, prior to each due date of the principal of or any
premium or interest on any Securities of that series, deposit with a Paying
Agent a sum sufficient to pay such amount, such sum to be held as provided by
the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the
Company will promptly notify the Trustee of its action or failure so to act.

         The Company will cause each Paying Agent for any series of Securities
other than the Trustee to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section, that such Paying Agent will (i) comply with the provisions of
the Trust Indenture Act applicable to it as a Paying Agent and (ii) during the
continuance of any default by the Company (or any other obligor upon the
Securities of that series) in the making of any payment in respect of the
Securities of that series, and upon the written request of the Trustee,
forthwith pay to the Trustee all sums held in trust by such Paying Agent for
payment in respect of the Securities of that series.

         The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such money.

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of or any premium or
interest



                                      -59-
<PAGE>   67
on any Security of any series and remaining unclaimed for two years after such
principal, premium or interest has become due and payable shall be paid to the
Company on Company Request, or (if then held by the Company) shall be discharged
from such trust; and the Holder of such Security shall thereafter, as an
unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; PROVIDED, HOWEVER, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause to
be published once, in a newspaper published in the English language, customarily
published on each Business Day and of general circulation in The City of New
York, notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such publication,
any unclaimed balance of such money then remaining will be repaid to the Company
free of the trust formerly impressed upon it.

Section 1004. STATEMENT BY OFFICERS AS TO DEFAULT.

         The Company will deliver to the Trustee, within 120 days after the end
of each fiscal year of the Company ending after the date hereof, an Officers'
Certificate, one of the signers of which shall be the principal executive
officer, principal financial officer or principal accounting officer of the
Company, stating whether or not to the best knowledge of the signers thereof the
Company is in default in the performance and observance of any of the terms,
provisions and conditions of this Indenture (without regard to any period of
grace or requirement of notice provided hereunder) and, if the Company shall be
in default, specifying all such defaults and the nature and status thereof of
which they may have knowledge.

Section 1005. EXISTENCE.

         Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its legal
existence.

Section 1006. LIMITATION ON SECURED FUNDED DEBT.

         The Company shall not create, assume, guarantee, incur or issue any
Secured Funded Debt, or permit any Restricted Subsidiary so to do, without
making effective provision whereby the Securities then outstanding and having
the benefit of this Section shall be secured equally and ratably with (or prior
to) such Secured Funded Debt for so long as such debt shall be so secured,
except that the foregoing shall not prevent the Company or any Restricted
Subsidiary (without providing for any ratable security for the Holders of the
Securities) from creating, assuming, guaranteeing, incurring or issuing Secured
Funded Debt of the following character:

         foregoing, to secure partial, progress, advance or other payments or
         performance pursuant to the provisions of any contract or statute;

              (9)  any Secured Funded Debt if immediately after giving effect to
         the incurrence or issuance thereof, the sum of the aggregate amount of

term, provision or condition set forth in Sections 801, 1006, 1007 and 1008,

time for such compliance the Holders of at least a majority in principal amount
of the Outstanding Securities of such series shall, by Act of such Holders,
either waive such compliance in such instance or generally waive compliance with
such term, provision or condition, but no such waiver shall extend to or affect
such term, provision or condition except to the extent so expressly waived, and,

Section 1102. ELECTION TO REDEEM: NOTICE TO TRUSTEE.

         The election of the Company to redeem any Securities shall be evidenced
by or pursuant to a Board Resolution or Officers' Certificate. In case of any
redemption at the election of the Company of the Securities of any series, the
Company shall, at least 60 days prior to the Redemption Date fixed by the
Company (unless a shorter notice shall be satisfactory to the Trustee), notify
the Trustee of such Redemption Date, of the principal amount of Securities of
such series to be redeemed and, if applicable, of the tenor of the Securities to
be redeemed. In the case of any redemption of Securities prior to the expiration
of any restriction on such redemption provided in the terms of such Securities
or elsewhere in this Indenture, the Company shall furnish the Trustee with an
Officers' Certificate evidencing compliance with such restriction.

Section 1103. SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

         If less than all the Securities of any series are to be redeemed
(unless all of the Securities of such series and of a specified tenor are to be
redeemed), the particular Securities to be redeemed shall be selected not more
than 60 days prior to the Redemption Date by the Trustee, from the Outstanding
Securities of such series not previously called for redemption, by such method
as the Trustee shall deem fair and appropriate and which may provide for the
selection for redemption a portion of the principal amount of any Security of
such series, provided that the unredeemed portion of the principal amount of any
Security shall be in an authorized denomination (which shall not be less than
the minimum authorized denomination or any integral multiple thereof) for such
Security. If less than all of the Securities of such series and of a specified
tenor are to be redeemed, the particular Securities to be redeemed shall be
selected not more than 60 days prior to the Redemption Date by the Trustee, from
the Outstanding Securities of such series and specified tenor not previously
called for redemption in accordance with the preceding sentence.

         The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption and, in the case of any Securities selected
for partial redemption, the principal amount thereof to be redeemed.

         For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Securities redeemed or to be redeemed only in part, to the
portion of the principal amount of such Securities which has been or is to be
redeemed.

Section 1104. NOTICE OF REDEMPTION.

         Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption

the Security Register.

         All notices of redemption shall identify the Securities to be redeemed

              (2)   the Redemption Price,

              (3)   if less than all the Outstanding Securities of any series
         are to be redeemed, the identification (and, in the case of partial
         redemption of any Securities, the principal amounts) of the particular
         Securities to be redeemed,

              (4)   that on the Redemption Date the Redemption Price will become
         due and payable upon each such Security, or portion thereof, to be
         redeemed and, if applicable, that interest thereon will cease to accrue
         on and after said date,

              (5)   the place or places where such Securities are to be
         surrendered for payment of the Redemption Price, and

              (6)   that the redemption is for a sinking fund, if such is the
         case.

         Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.

Section 1105. DEPOSIT OF REDEMPTION PRICE.

         Prior to 12:00 noon New York City time on any Redemption Date, the
Company shall deposit with the Trustee or with a Paying Agent (or, if the
Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 1003) an amount of money in the currency or currencies in
which the Securities of such series are payable (except as otherwise specified
pursuant to Section 301 for the Securities of such series) sufficient to pay the

Section 1106. SECURITIES PAYABLE ON REDEMPTION DATE.

         Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption Price, together with accrued interest
to the Redemption Date; PROVIDED, HOWEVER, that, unless otherwise specified as
contemplated by Section 301, installments of interest whose Stated Maturity is
on or prior to the Redemption Date shall be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 307.

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal and any premium shall, until
paid, bear interest from the Redemption Date at the rate prescribed therefor in
the Security.

Section 1107. SECURITIES REDEEMED IN PART.

         Any Security which is to be redeemed only in part shall be surrendered
at a Place of Payment therefor (with, if the Company or the Trustee so requires,
due endorsement by, or a written instrument of transfer in form satisfactory to
the Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and deliver or make available for delivery to the Holder of
such Security without service charge, a new Security or Securities of the same
series and of like tenor, of any authorized denomination as requested by such
Holder, in aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Security so surrendered.

                                  Sinking Funds

Section 1201. APPLICABILITY OF ARTICLE.

         The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of a series except as otherwise specified as
contemplated by Section 301 for Securities of such series.

         The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund



                                      -66-

payment", and any payment in excess of such minimum amount provided for by the
terms of Securities of any series is herein referred to as an "optional sinking
fund payment". If provided for by the terms of Securities of any series, the
cash amount of any sinking fund payment may be subject to reduction as provided
in Section 1202. Each sinking fund payment shall be applied to the redemption of
Securities of any series as provided for by the terms of Securities of such
series.

Section 1202. SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

         The Company (1) may deliver Outstanding Securities of a series (other
than any previously called for redemption) and (2) may apply as a credit
Securities of a series which have been redeemed either at the election of the
Company pursuant to the terms of such Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, in each case in satisfaction of all or any part of any sinking fund
payment with respect to the Securities of such series required to be made
pursuant to the terms of such Securities as provided for by the terms of such
series; PROVIDED that such Securities have not been previously so credited. Such
Securities shall be received and credited for such purpose by the Trustee at the
Redemption Price specified in such Securities for redemption through operation
of the sinking fund and the amount of such sinking fund payment shall be reduced
accordingly.

Section 1203. REDEMPTION OF SECURITIES FOR SINKING FUND.

         Not less than 45 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
that series pursuant to the terms of that series, the portion thereof, if any,
which is to be satisfied by payment of cash and the portion thereof, if any,
which is to be satisfied by delivering and crediting Securities of that series
pursuant to Section 1202 and will also deliver to the Trustee any Securities to
be so delivered. Not less than 30 days before each such sinking fund payment
date the Trustee shall select the Securities to be redeemed upon such sinking
fund payment date in the manner specified in Section 1103 and cause notice of
the redemption thereof to be given in the name of and at the expense of the
Company in the manner provided in Section 1104. Such notice having been duly
given, the redemption of such Securities shall be made upon the terms and in the
manner stated in Sections 1106 and 1107.

Section 1301. APPLICABILITY OF ARTICLE; COMPANY'S OPTION TO EFFECT DEFEASANCE OR
              COVENANT DEFEASANCE.

         Unless pursuant to Section 301 provision is made that either or both
(a) defeasance of the Securities of a series under Section 1302 or (b) covenant
defeasance of the Securities of a series under Section 1303 shall not be
applicable to the Securities of any series, then the provisions of such Section
or Sections, as the case may be, together with the other provisions of this
Article Thirteen, with such modifications thereto as may be specified pursuant
to Section 301 with respect to any Securities, shall be applicable to the
Securities of such series, and the Company may at its option by Board
Resolution, at any time, with respect to the Securities of such series, elect to
have either Section 1302 (if applicable) or Section 1303 (if applicable) applied
to the Outstanding Securities of such series upon compliance with the conditions
set forth below in this Article Thirteen.

Section 1302. DEFEASANCE AND DISCHARGE.

         Upon the Company's exercise of its option to have this Section applied
to any series of Securities the Company shall be deemed to have been discharged
from its obligations with respect to the Outstanding Securities of such series
on and after the date the conditions precedent set forth below are satisfied
(hereinafter, "defeasance"). For this purpose, such defeasance means that the
Company shall be deemed to have paid and discharged the entire indebtedness
represented by and obligations under, the Outstanding Securities of such series
which shall thereafter be deemed to be "Outstanding" only for the purposes of
the Sections of this Indenture referred to in clauses (A) and (B) of this
Section, and to have satisfied all its other obligations under such Securities
and this Indenture insofar as such Securities are concerned (and the Trustee, at
the expense of the Company, shall execute proper instruments acknowledging the
same), except for the following which shall survive until otherwise terminated
or discharged hereunder: (A) the rights of Holders of Outstanding Securities of
such series to receive, solely from the trust fund described in Section 1304 as
more fully set forth in such Section, payments of the principal of (and premium,
if any) and interest on such Securities when such payments are due, and (B) the
Company's obligations with respect to such Securities under Sections 305, 306,
1002 and 1003 and such obligations as shall be ancillary thereto. Subject to
compliance with this Article Thirteen, the Company may exercise its option under
this Section 1302 notwithstanding the prior exercise of its option under Section
1303 with respect to the Securities of such series. Following a defeasance,
payment of such Securities may not be accelerated because of an Event of
Default.

Section 1303. COVENANT DEFEASANCE.

         Upon the Company's exercise of its option (if any) to have this Section
applied to any series of Securities, the Company shall be released from its
obligations under Sections 801, 1006, 1007, 1008 (and any covenant made
applicable to such Securities pursuant to Section 301), the occurrence of an
event specified in Sections 501(4) through 501(8) (and any other Event of
Default applicable to such Securities that are determined pursuant to Section
301 to be subject to this provision) shall not be deemed to be an Event of
Default with respect to the Outstanding Securities of such series on and after
the date the conditions set forth below are satisfied (hereinafter, "covenant
defeasance"), and such Securities shall thereafter be deemed not to be
"Outstanding" for the purposes of any direction, waiver, consent or declaration
or Act of Holders (and the consequences of any thereof) in connection with
Sections 801, 1006, 1007 or 1008 (and any other covenant made applicable to such
Security pursuant to Section 301), but shall continue to be deemed "Outstanding"
for all other purposes hereunder. For this purpose, such covenant defeasance
means that, with respect to the Outstanding Securities of such series, the
Company may omit to comply with and shall have no liability in respect of any
term, condition or limitation set forth in any such Section or such other
covenant whether directly or indirectly by reason of any reference elsewhere
herein to any such Section or such other covenant or by reason of any reference
in any such Section or such other covenant to any other provision herein or in
any other document, but the remainder of this Indenture and such Securities
shall be unaffected thereby.

Section 1304. CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

         The following shall be the conditions precedent to application of
either Section 1302 or Section 1303 to the Outstanding Securities of or within
such series:

              (1)   The Company shall have deposited or caused to be deposited

         Section 609 who shall agree to comply with the provisions of this
         Article Thirteen applicable to it) as trust funds in trust for the
         purpose of making the following payments, specifically pledged as
         security for, and dedicated solely to, the benefit of the Holders of
         such Securities, (A) money in an amount (in such currency, currencies
         or currency units in which such Securities are then specified as
         payable at Maturity), or (B) U.S. Government Obligations which through
         the scheduled payment of principal and interest in respect thereof in
         accordance with their terms will provide, not later than one day before
         the due date of any payment, money in an amount, or (C) a combination
         thereof in an amount, sufficient, in the opinion of a nationally
         recognized firm of independent public accountants expressed in a
         written certification thereof delivered to the Trustee, to pay and
         discharge, and which shall be applied by the Trustee (or other
         qualifying trustee) to pay and discharge, (i) the principal



                                      -69-
<PAGE>   77
         of (and premium, if any) and interest on the Outstanding Securities of
         such series on the Maturity of such principal, premium, if any, or
         interest and (ii) any mandatory sinking fund payments applicable to
         such Securities on the day on which such payments are due and payable
         in accordance with the terms of this Indenture and such Securities.
         Before such a deposit the Company may make arrangements satisfactory to
         the Trustee for the redemption of Securities at a future date or dates
         in accordance with Article Eleven, which shall be given effect in
         applying the foregoing. For this purpose, "U.S. Government Obligations"
         means securities that are (x) direct obligations of the United States
         of America for the payment of which its full faith and credit is
         pledged or (y) obligations of a Person controlled or supervised by and
         acting as an agency or instrumentality of the United States of America
         the payment of which is unconditionally guaranteed as a full faith and
         credit obligation by the United States of America, which, in either
         case, are not callable or redeemable at the option of the issuer
         thereof, and shall also include a depositary receipt issued by a bank
         (as defined in Section 3(a)(2) of the Securities Act of 1933, as
         amended) as custodian with respect to any such U.S. Government
         Obligation or a specific payment of principal of or interest on any
         such U.S. Government Obligation held by such custodian for the account
         of the holder of such depositary receipt, provided that (except as
         required by law) such custodian is not authorized to make any deduction
         from the amount payable to the holder of such depositary receipt from
         any amount received by the custodian in respect of the U.S. Government
         Obligation or the specific payment of principal of or interest on the
         U.S. Government Obligation evidenced by such depositary receipt.

              (2)   No Event of Default or event which with notice or lapse of
         time or both would become an Event of Default with respect to the
         Securities of such series shall have occurred and be continuing on the
         date of such deposit.

              (3)   In the case of an election under Section 1302, the Company
         shall have delivered to the Trustee an Opinion of Counsel to the effect
         that, and based thereon such opinion shall confirm that, the Holders of
         the Outstanding Securities of such series will not recognize income,
         gain or loss for Federal income tax purposes as a result of such
         defeasance and will be subject to Federal income tax on the same
         amounts, in the same manner and at the same times as would have been
         the case if such defeasance had not occurred. Such opinion shall be
         based upon at least one of the following authorities (issued, enacted
         or promulgated after the date of this Indenture), substantially on
         point and to the foregoing effect: (i) a public ruling of the Internal
         Revenue Service, (ii) a private ruling of the Internal Revenue Service
         issued to the Company with respect to the Securities, (iii) a provision
         of the Internal Revenue Code, (iv) a final regulation promulgated by
         the Department of the Treasury, or (v) a change in the applicable
         Federal income tax law.

              (4)   In the case of an election under Section 1303, the Company
         shall have delivered to the Trustee an Opinion of Counsel to the effect
         that the Holders of the Outstanding Securities of such series will not
         recognize income, gain or loss for Federal income tax purposes as a
         result of such covenant defeasance and will be subject to Federal
         income tax on the same amounts, in the same manner and at the same
         times as would have been the case if such covenant defeasance had not
         occurred.

Section 1305. DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD IN
              TRUST; OTHER MISCELLANEOUS PROVISIONS.

         Subject to the provisions of the last paragraph of Section 1003, all
money and U.S. Government Obligations (including the proceeds thereof) deposited
with the Trustee or other qualifying trustee (collectively, for purposes of this
Section 1305, the "Trustee") pursuant to Section 1304 in respect of the
Outstanding Securities of such series shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Securities and this
Indenture, to the payment, either directly or through any Paying Agent (but not
including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities, of all sums due and to become due
thereon in respect of principal (and premium, if any) and interest, but such
money need not be segregated from other funds except to the extent required by
law.

         Anything herein to the contrary notwithstanding, the Trustee shall
deliver or pay to the Company from time to time upon Company Request any money
or U.S. Government Obligations held by it as provided in Section 1304 which in
the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to
effect an equivalent defeasance or covenant defeasance.

Section 1306. COUNTERPARTS.

         This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

         relating thereto;

              (2)   a brief statement as to the nature and scope of the
         examination or investigation upon which the statements or opinions
         contained in such certificate or opinion are based;

              (3)   a statement that, in the opinion of each such individual, he
         has made such examination or investigation as is necessary to enable
         him to express an informed opinion as to whether or not such covenant
         or condition has been complied with; and

              (4)   a statement as to whether, in the opinion of each such
         individual, such condition or covenant has been complied with.

Section 103. FORM OF DOCUMENTS DELIVERED TO TRUSTEE.

         In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

         Any certificate or opinion of an officer of the Company may be based,
insofar as it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous. Any such certificate or opinion of counsel may be based, insofar as
it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company




                                        9

<PAGE>   18
stating that the information with respect to such factual matters is in the
possession of the Company, unless such counsel knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to such matters are erroneous.

         Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

Section 104. ACTS OF HOLDERS; RECORD DATES.

         (a)   Any request, demand, authorization, direction, notice, consent,
waiver or other action provided or permitted by this Indenture to be given, made
or taken by Holders may be embodied in and evidenced by one or more instruments
of substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to a Responsible Officer of the Trustee and, where it is hereby expressly
required, to the Company. Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"Act" of the Holders signing such instrument or instruments. Proof of execution
of any such instrument or of a writing appointing any such agent shall be
sufficient for any purpose of this Indenture and (subject to Section 601)
conclusive in favor of the Trustee and the Company, if made in the manner
provided in this Section.

         (b)   The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which the Trustee deems sufficient.

         (c)   The Company may, in the circumstances permitted by the Trust
Indenture Act, fix any day as the record date for the purpose of determining the
Holders of Securities of any series entitled to give or take any request,
demand, authorization, direction, notice, consent, waiver or other action, or to
vote on any action, authorized or permitted to be given or taken by Holders of
Securities of such series. If not set by the Company prior to the first
solicitation of a Holder of Securities of such series made by any Person in
respect of any such action, or, in the




                                       10

<PAGE>   19
case of any such vote, prior to such vote, the record date for any such action
or vote shall be the 30th day (or, if later, the date of the most recent list of
Holders required to be provided pursuant to Section 701) prior to such first
solicitation or vote, as the case may be. With regard to any record date for
action to be taken by the Holders of one or more series of Securities, only the
Holders of Securities of such series on such date (or their duly designated
proxies) shall be entitled to give or take, or vote on, the relevant action.

         (d)   The ownership of Securities shall be proved by the Security
Register.

         (e)   Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Holder of any Security shall bind every future Holder
of the same Security and the Holder of every Security issued upon the
registration of transfer thereof or in exchange therefor or in lieu thereof in
respect of anything done, omitted or suffered to be done by the Trustee or the
Company in reliance thereon, whether or not notation of such action is made upon
such Security.

Section 105. NOTICES, ETC., TO TRUSTEE AND COMPANY.

         Any request, demand, authorization, direction, notice, consent, waiver
or Act of Holders or other document provided or permitted by this Indenture to
be made upon, given or furnished to, or filed with,

              (1)   the Trustee by any Holder or by the Company shall be
         sufficient for every purpose hereunder if made, given, furnished or
         filed in writing to or with a Responsible Officer of the Trustee at its
         Corporate Trust Office, or

              (2)   the Company by the Trustee or by any Holder shall be
         sufficient for every purpose hereunder (unless otherwise herein
         expressly provided) if in writing and mailed, first-class postage
         prepaid, to the Company addressed to it at the address of its principal
         office specified in the first paragraph of this instrument or at any
         other address previously furnished in writing to a Responsible Officer
         of the Trustee by the Company.

Section 106. NOTICE TO HOLDERS; WAIVER.

         Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such event, at his address as it appears in the Security Register, not later
than the latest date (if any), and not earlier than the earliest date (if any),
prescribed for the giving of such notice. In any case where notice to Holders is
given by mail, neither the failure to mail such notice, nor any defect in any
notice so mailed, to any particular Holder shall affect




                                       11

<PAGE>   20
the sufficiency of such notice with respect to other Holders. Any notice mailed
to a Holder in the manner herein prescribed shall be conclusively deemed to have
been received by such Holder, whether or not such Holder actually receives such
notice. Where this Indenture provides for notice in any manner, such notice may
be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Holders shall be filed with the Trustee, but such
filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

         In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of a Responsible
Officer of the Trustee shall constitute a sufficient notification for every
purpose hereunder.

Section 107. CONFLICT WITH TRUST INDENTURE ACT.

         If any provision hereof limits, qualifies or conflicts with a provision
of the Trust Indenture Act that is required under such Act to be a part of and
govern this Indenture, the latter provision shall control. If any provision of
this Indenture modifies or excludes any provision of the Trust Indenture Act
that may be so modified or excluded, the latter provision shall be deemed to
apply to this Indenture as so modified or to be excluded, as the case may be.

Section 108. EFFECT OF HEADINGS AND TABLE OF CONTENTS.

         The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction hereof.

Section 109. SUCCESSORS AND ASSIGNS.

         All covenants and agreements in this Indenture by the Company shall
bind its successors and assigns, whether so expressed or not.

Section 110. SEPARABILITY CLAUSE.

         In case any provision in this Indenture or in the Securities shall be
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

Section 111. BENEFITS OF INDENTURE.

         Nothing in this Indenture or in the Securities, express or implied,
shall give to any Person, other than the parties hereto and their successors
hereunder and the




                                       12

<PAGE>   21
Holders, any benefit or any legal or equitable right, remedy or claim under this
Indenture.

Section 112. GOVERNING LAW.

         THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE COMMONWEALTH OF MASSACHUSETTS WITHOUT REGARD TO
CONFLICTS OF LAW PRINCIPLES THEREOF.

Section 113. LEGAL HOLIDAYS.

         In any case where any Interest Payment Date, Redemption Date, Stated
Maturity or Maturity of any Security shall not be a Business Day at any Place of
Payment, then (notwithstanding any other provision of this Indenture or of the
Securities (other than a provision of the Securities of any series which
specifically states that such provision shall apply in lieu of this Section))
payment of interest or principal (and premium, if any) need not be made at such
Place of Payment on such date, but may be made on the next succeeding Business
Day at such Place of Payment with the same force and effect as if made on the
Interest Payment Date, the Redemption Date, or at the Stated Maturity or
Maturity, PROVIDED THAT no interest shall accrue for the period from and after
such Interest Payment Date, Redemption Date, Stated Maturity Date or Maturity,
as the case may be.

hereof elects to convert this Security, or if less than the entire principal
amount hereof is to be converted, the portion hereof to be converted, and, in
case such surrender shall be made during the period from the close of business

the Indenture. In addition, the Indenture provides that in case of certain
consolidations or mergers to which the Company is a party or the transfer of
substantially all of the assets of the Company, the Indenture shall be amended,
without the consent of any Holders of Securities, so that this Security, if then
outstanding, will be convertible thereafter, during the period this Security
shall be convertible as specified above, only into the kind and amount of
securities, cash and other property receivable upon the consolidation, merger or
transfer by a holder of the number of shares of Common Stock into which this
Security might have been converted immediately prior to such consolidation,
merger or transfer (assuming such holder of Common Stock failed to exercise any
rights of election and received per share the kind and amount received per share
by a plurality of non-electing shares), assuming, if such consolidation, merger
or transfer is prior to [insert date upon which the Securities first become
convertible], that this Security was convertible at the time of such
consolidation, merger or transfer at the initial conversion price specified
above as adjusted from __________________, to such time pursuant to the
Indenture.]

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of a majority in principal amount of the Securities at
the time Outstanding of each series to be affected. The Indenture also contains
provisions permitting the Holders of specified percentages in principal amount
of the Securities of each series at the time Outstanding, on behalf of the
Holders of all Securities of such series, to waive compliance by the Company
with certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences. Any such consent or waiver by the Holder of
this Security shall be conclusive and binding upon such Holder and upon all
future Holders of this Security and of any Security issued upon the registration
of transfer hereof or in exchange herefor or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Security.

         No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of and any premium and
interest on this Security at the times, place and rate, and in the coin or
currency, herein prescribed.

Section 302. DENOMINATIONS.

         The Securities of each series shall be issuable in registered form
without coupons in such denominations as shall be specified as contemplated by
Section 301. In the absence of any such provisions with respect to the
Securities of any series, the Securities of such series shall be issuable in
denominations of $1,000 and any integral multiple thereof.

Section 303. EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

         The Securities shall be executed on behalf of the Company by its
Chairman of the Board, its Chief Executive Officer, its President, its Chief
Financial Officer or one of its Vice Presidents, under its corporate seal
reproduced thereon attested by its Clerk or one of its Assistant Clerks. The
signature of any of these officers on the Securities may be manual or facsimile.

         Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with the Company Order shall authenticate and deliver or make available for
delivery such Securities; PROVIDED, HOWEVER, that, in the case of Securities of
a series that are not to be originally issued at one time, the Trustee shall
authenticate and deliver or make available for delivery such Securities from
time to time in accordance with such other procedures (including, without
limitation, the receipt by the Trustee of oral or electronic instructions from
the Company or its duly authorized agents, promptly confirmed in writing)
acceptable to the Trustee as may be specified by or pursuant to a Company Order
delivered to a Responsible Officer of the Trustee prior to the time of the first
authentication of Securities of such series. If the form or terms of the
Securities of the series have been established in or pursuant to one or more
Board Resolutions as permitted by Sections 201 and 301, in authenticating such
Securities, and accepting the additional responsibilities under this Indenture
in relation to such Securities, the Trustee shall be entitled to receive, and
(subject to Section 601) shall be fully protected in relying upon, an Opinion of
Counsel stating,

              (a)   if the form of such Securities has been established by or
         pursuant to Board Resolution as permitted by Section 201, that such
         form has been established in conformity with the provisions of this
         Indenture;




                                       26


<PAGE>   35
              (b)   if the terms of such Securities have been established by or
         pursuant to Board Resolution as permitted by Section 301, that such
         terms have been established in conformity with the provisions of this
         Indenture; and

              (c)   that such Securities, when authenticated and delivered by
         the Trustee and issued by the Company in the manner and subject to any
         conditions specified in such Opinion of Counsel, will constitute valid
         and legally binding obligations of the Company enforceable in
         accordance with their terms, subject to bankruptcy, insolvency,
         fraudulent transfer, reorganization, moratorium and similar laws of
         general applicability relating to or affecting creditors' rights and to
         general equity principles.

If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

         Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the time
of authentication of each Security of such series if such documents, with
appropriate modifications to cover such future issuances, are delivered at or
prior to the authentication upon original issuance of the first Security of such
series to be issued.

         If the Company shall establish pursuant to Section 301 that the
Securities of a series are to be issued in whole or in part in the form of one
or more Book-Entry Securities, then the Company shall execute and the Trustee
shall, in accordance with this Section and the Company Order with respect to
such series, authenticate and deliver or make available for delivery one or more
Securities in such form that (i) shall represent and shall be denominated in an
amount equal to the aggregate principal amount of the Outstanding Securities of
such series to be represented by such Book-Entry Security or Securities, or such
portion thereof as the Company shall specify in a Company Order, (ii) shall be
registered in the name of the Depositary for such Book-Entry Security or
Securities or the nominee of such Depositary, (iii) shall be delivered by the
Trustee to such Depositary or pursuant to such Depositary's instruction and (iv)
shall bear the legend substantially to the effect set forth in Section 204.

         Unless otherwise established pursuant to Section 301, each Depositary
designated pursuant to Section 301 for a Book-Entry Security must, at the time
of its




                                       27

<PAGE>   36
designation and at all times while it serves as Depositary, be a clearing agency
registered under the Securities Exchange Act of 1934 and any other applicable
statute or regulation. The Trustee shall have no responsibility to determine if
the Depositary is so registered. Each Depositary shall enter into an agreement
with the Trustee governing the respective duties and rights of such Depositary
and the Trustee with regard to Book-Entry Securities.

         Unless otherwise provided in the form of Security for any series, each
Security shall be dated the date of its authentication.

         No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly authenticated and delivered hereunder. Notwithstanding the
foregoing, if any Security shall have been authenticated and delivered hereunder
but never issued and sold by the Company, and the Company shall deliver such
Security to the Trustee for cancellation as provided in Section 309, for all
purposes of this Indenture such Security shall be deemed never to have been
authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture.

Section 304. TEMPORARY SECURITIES.

         Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver or make available for delivery, temporary Securities which are printed,
lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the definitive Securities in lieu of
which they are issued and with such appropriate insertions, omissions,
substitutions and other variations as the officers executing such Securities may
determine, as evidenced by their execution of such Securities.

         If temporary Securities of any series are issued, the Company will
cause definitive Securities of that series to be prepared without unreasonable
delay. After the preparation of definitive Securities of such series, the
temporary Securities of such series shall be exchangeable for definitive
Securities of such series upon surrender of the temporary Securities of such
series at the office or agency of the Company in a Place of Payment for that
series, without charge to the Holder. Upon surrender for cancellation of any one
or more temporary Securities of any series the Company shall execute and the
Trustee shall authenticate and deliver or make available for delivery in
exchange therefor one or more definitive Securities of the same series, of any
authorized denominations and of a like aggregate principal amount and tenor.
Until so exchanged the temporary Securities of any series shall in all respects
be entitled to




                                       28

<PAGE>   37
the same benefits under this Indenture as definitive Securities of such series
and tenor.

Section 305. REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

         The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the register maintained in such office and in any other
office or agency of the Company in a Place of Payment being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities. The Trustee is hereby
appointed "Security Registrar" for the purpose of registering Securities and
transfers of Securities as herein provided.

         Upon surrender for registration of transfer of any Security of any
series at the office or agency in a Place of Payment for that series, the
Company shall execute, and the Trustee shall authenticate and deliver or make
available for delivery, in the name of the designated transferee or transferees,
one or more new Securities of the same series, of any authorized denominations
and of a like aggregate principal amount and tenor.

         At the option of the Holder, Securities of any series may be exchanged
for other Securities of the same series, of any authorized denominations and of
a like aggregate principal amount and tenor, upon surrender of the Securities to
be exchanged at such office or agency. Whenever any Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver or make available for delivery, the Securities which
the Holder making the exchange is entitled to receive.

         All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

         Every Security presented or surrendered for registration of transfer or
for exchange shall (if so required by the Company, the Security Registrar or the
Trustee) be duly endorsed, or be accompanied by a written instrument of transfer
in form satisfactory to the Company, the Security Registrar and the Trustee duly
executed, by the Holder thereof or his attorney duly authorized in writing.

         No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.




                                       29

<PAGE>   38
         The Company shall not be required (i) to issue, register the transfer
of or exchange Securities of any series during a period beginning at the opening
of business 15 days before the day of the mailing of a notice of redemption of
Securities of that series selected for redemption under Section 1103 and ending
at the close of business on the day of such mailing, or (ii) to register the
transfer of or exchange any Security so selected for redemption in whole or in
part, except the unredeemed portion of any Security being redeemed in part.

         Notwithstanding the foregoing, any Book-Entry Security shall be
exchangeable pursuant to this Section 305 for Securities registered in the names
of Persons other than the Depositary for such Security or its nominee only if
(i) such Depositary notifies the Company that it is unwilling or unable to
continue as Depositary for such Book-Entry Security or if at any time such
Depositary ceases to be a clearing agency registered under the Securities
Exchange Act of 1934, as amended, (ii) the Company executes and delivers to the
Trustee a Company Order that such Book-Entry Security shall be so exchangeable
or (iii) there shall have occurred and be continuing an Event of Default with
respect to the Securities. Any Book-Entry Security that is exchangeable pursuant
to the preceding sentence shall be exchangeable for Securities registered in
such names as such Depositary shall direct.

         Notwithstanding any other provision in this Indenture, unless and until
it is exchanged in whole or in part for Securities that are not in the form of a
Book-Entry Security, a Book-Entry Security may not be transferred or exchanged
except as a whole by the Depositary with respect to such Book-Entry Security to
a nominee of such Depositary or by a nominee of such Depositary to such
Depositary or another nominee of such Depositary.

Section 306. MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

         If any mutilated Security is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver or make available
for delivery in exchange therefor a new Security of the same series and of like
tenor and principal amount and bearing a number not contemporaneously
outstanding.

         If there shall be delivered to the Company and the Trustee (i) evidence
to their satisfaction of the destruction, loss or theft of any Security and (ii)
such security or indemnity as may be required by them to save each of them and
any agent of either of them harmless, then, in the absence of notice to the
Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute and the Trustee shall authenticate and
deliver, in lieu of any such destroyed, lost or stolen Security, a new Security
of the same series and of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

<PAGE>   39
         In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.

         Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

         Every new Security of any series issued pursuant to this Section in
lieu of any destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities of that series duly issued hereunder.

         The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.

Section 307. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

         Except as otherwise contemplated by Section 301 with respect to any
series of Securities, interest on any Security which is payable, and is
punctually paid or duly provided for, on any Interest Payment Date shall be paid
to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest at the office or agency maintained for such purpose pursuant
to Section 1002; PROVIDED, HOWEVER, that at the option of the Company, interest
on Securities of any series that bear interest may be paid (i) by check mailed
to the address of the Person entitled thereto as it shall appear on the Security
Register or (ii) by wire transfer to an account maintained by the Person
entitled thereto as specified in the Security Register.

         Any interest on any Security of any series which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in Clause (1) or (2) below:

              (1)   The Company may elect to make payment of any Defaulted
         Interest to the Persons in whose names the Securities of such series
         (or their respective Predecessor Securities) are registered at the
         close of business on a Special Record Date for the payment of such
         Defaulted Interest, which shall be




                                       31

<PAGE>   40
         fixed in the following manner. The Company shall notify the Trustee in
         writing of the amount of Defaulted Interest proposed to be paid on each
         Security of such series and the date of the proposed payment, and at
         the same time the Company shall deposit with the Trustee an amount of
         money equal to the aggregate amount proposed to be paid in respect of
         such Defaulted Interest or shall make arrangements satisfactory to the
         Trustee for such deposit prior to the date of the proposed payment,
         such money when deposited to be held in trust for the benefit of the
         Persons entitled to such Defaulted Interest as in this Clause provided.
         Thereupon the Trustee shall fix a Special Record Date for the payment
         of such Defaulted Interest which shall be not more than 15 days and not
         less than 10 days prior to the date of the proposed payment and not
         less than 10 days after the receipt by the Trustee of the notice of the
         proposed payment. The Trustee shall promptly notify the Company of such
         Special Record Date and, in the name and at the expense of the Company,
         shall cause notice of the proposed payment of such Defaulted Interest
         and the Special Record Date therefor to be mailed, first-class postage
         prepaid, to each Holder of Securities of such series at his address as
         it appears in the Security Register, not less than 10 days prior to
         such Special Record Date. Notice of the proposed payment of such
         Defaulted Interest and the Special Record Date therefor having been so
         mailed, such Defaulted Interest shall be paid to the Persons in whose
         names the Securities of such series (or their respective Predecessor
         Securities) are registered at the close of business on such Special
         Record Date and shall no longer be payable pursuant to the following
         Clause (2).

              (2)   The Company may make payment of any Defaulted Interest on
         the Securities of any series in any other lawful manner not
         inconsistent with the requirements of any securities exchange on which
         such Securities may be listed, and upon such notice as may be required
         by such exchange, if, after notice given by the Company to the Trustee
         of the proposed payment pursuant to this Clause, such manner of payment
         shall be deemed practicable by the Trustee.

         In the case of any Security which is converted after any Regular Record
Date and on or prior to the next succeeding Interest Payment Date (other than
any Security whose Maturity is prior to such Interest Payment Date), interest
whose Stated Maturity is on such Interest Payment Date shall be payable on such
Interest Payment Date notwithstanding such conversion, and such interest
(whether or not punctually paid or duly provided for) shall be paid to the
Person in whose name that Security (or one or more Predecessor Securities) is
registered at the close of business on such Regular Record Date. Except as
otherwise expressly provided in the immediately preceding sentence, in the case
of any Security which is converted, interest whose Stated Maturity is after the
date of conversion of such Security shall not be payable.




                                       32

<PAGE>   41
         Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

Section 308. PERSONS DEEMED OWNERS.

         Prior to due presentment of a Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment of principal of and any premium
and (subject to Section 307) any interest on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.

Section 309. CANCELLATION.

         All Securities surrendered for payment, redemption, conversion,
registration of transfer or exchange or for credit against any sinking fund
payment shall, if surrendered to any Person other than the Trustee, be delivered
to the Trustee. All Securities so delivered and any Securities surrendered
directly to the Trustee for any such purpose shall be promptly cancelled by the
Trustee and such cancellation shall be noted conspicuously on each such
Security. The Company may at any time deliver to the Trustee for cancellation
any Securities previously authenticated and delivered hereunder which the
Company may have acquired in any manner whatsoever, and may deliver to the
Trustee (or to any other Person for delivery to the Trustee) for cancellation
any Securities previously authenticated hereunder which the Company has not
issued and sold, and all Securities so delivered shall be promptly cancelled by
the Trustee. No Securities shall be authenticated in lieu of or in exchange for
any Securities cancelled as provided in this Section, except as expressly
permitted by this Indenture. Unless the Company directs otherwise by a Company
Order, all cancelled Securities held by the Trustee may be destroyed, but the
Trustee shall not be obligated to so destroy such Securities, and, if any such
cancelled Security is destroyed, the Trustee shall furnish to the Company a
certificate with respect to such destruction.

Section 310. COMPUTATION OF INTEREST.

         Except as otherwise specified as contemplated by Section 301 for
Securities of any series, interest on the Securities of each series shall be
computed on the basis of a 360-day year of twelve 30-day months.

Section 311. CUSIP NUMBERS.

         The Company in issuing the Securities may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices
of redemption as a convenience to Holders; PROVIDED that any such notice may
state that no representation is made as to the correctness of such numbers
either as printed on the Securities or as contained in any notice of a
redemption and that reliance may be placed only on the other identification
numbers printed on the Securities, and any such redemption shall not be affected
by any defect in or omission of such CUSIP numbers. The Company will promptly
notify the Trustee of any change in the CUSIP numbers.

                           Satisfaction and Discharge

Section 401. SATISFACTION AND DISCHARGE OF INDENTURE.

         This Indenture shall upon Company Request cease to be of further effect
with respect to Securities of any series (except as to any surviving rights of
registration of transfer, exchange or replacement of such Securities herein
expressly provided for), and the Trustee, at the expense of the Company, shall
execute proper instruments acknowledging satisfaction and discharge of this
Indenture with respect to such Securities, including, but not limited to,
Article Thirteen hereof, when

              (1)   either

                     (A)   all such Securities theretofore authenticated and
              delivered (other than (i) such Securities which have been
              destroyed, lost or stolen and which have been replaced or paid as
              provided in Section 306 and (ii) such Securities for whose payment
              money has theretofore been deposited in trust or segregated and
              held in trust by the Company and thereafter repaid to the Company
              or discharged from such trust, as provided in Section 1003) have
              been delivered to the Trustee for cancellation; or

                     (B)   all such Securities not theretofore delivered to the
              Trustee for cancellation

                           (i)    have become due and payable, or

                           (ii)   will become due and payable at their Stated
              Maturity within one year, or

                           (iii)  are to be called for redemption within one
              year under arrangements satisfactory to the Trustee for the giving
              of notice of redemption by the Trustee in the name, and at the
              expense, of the Company

              and the Company, in the case of (B)(i), (ii) or (iii) above, has
              deposited or caused to be deposited with the Trustee as trust
              funds in trust for the purpose an amount in the currency or
              currencies or currency unit or units in which such Securities are
              payable sufficient to pay and discharge the entire indebtedness on
              such Securities not theretofore delivered to the Trustee for
              cancellation, for principal and any premium and interest to the
              date of such deposit (in the case of Securities which have become
              due and payable) or to the Stated Maturity or Redemption Date, as
              the case may be;

              (2)   the Company has paid or caused to be paid all other sums
         payable hereunder by the Company; and

              (3)   the Company has delivered to the Trustee an Officers'
         Certificate and an Opinion of Counsel, each stating that all conditions
         precedent herein provided for relating to the satisfaction and
         discharge of this Indenture with respect to such Securities have been
         complied with.

         Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 607, the obligations of
the Trustee to any Authenticating Agent under Section 614 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of Clause (1) of
this Section, the obligations of the Trustee under Section 402, Article Six and
the last paragraph of Section 1003 shall survive.

Section 402. APPLICATION OF TRUST MONEY.

         Subject to provisions of the last paragraph of Section 1003, all money
deposited with the Trustee pursuant to Section 401 shall be held in trust and
applied by it, in accordance with the provisions of the Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal and any premium and
interest for whose payment such money has been deposited with the Trustee.

                                    Remedies

Section 501. EVENTS OF DEFAULT.

         "Event of Default", wherever used herein with respect to Securities of
any series, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body),
unless such event is either inapplicable to a particular series of Securities or
it is specifically deleted or modified in or pursuant to the supplemental
indenture or Board Resolution creating such series of Securities or in the form
of Security for such series:

              (1)   default in the payment of any interest upon any Security of
         that series when it becomes due and payable, and continuance of such
         default for a period of 30 days; or

              (2)   default in the payment of the principal of (or premium, if

         as due by the terms of a Security of that series; or

              (4)   default in the performance, or breach, of any covenant or
         warranty of the Company in this Indenture with respect to Securities of
         that series (other than a covenant or warranty a default in whose
         performance or whose breach is elsewhere in this Section specifically
         dealt with or which has expressly been included in this Indenture
         solely for the benefit of a series of Securities other than that
         series), and continuance of such default or breach for a period of 90
         days after there has been given, by registered or certified mail, to
         the Company by the Trustee or to the Company and the Trustee by the

         Securities of that series a written notice specifying such default or
         breach and requiring it to be remedied and stating that such notice is
         a "Notice of Default" hereunder; or

              (5)   if an event of default as defined in any mortgage, indenture
         or instrument under which there may be issued, or by which there may be
         secured or evidenced, any indebtedness for money borrowed of the
         Company or any Subsidiary, whether such indebtedness now exists or
         shall hereafter be created, if (A) such default either (1) results from
         the failure to pay the principal of any such indebtedness at its stated
         maturity or (2) relates to an obligation other than the obligation to
         pay the principal of such indebtedness

<PAGE>   45
         at its stated maturity and results in such indebtedness becoming or
         being declared due and payable prior to the date on which it would
         otherwise become due and payable, (B) the principal amount of such
         indebtedness, together with the principal amount of any other such
         indebtedness in default for failure to pay principal at stated maturity
         or the maturity of which has been so accelerated, aggregates
         $25,000,000 or more at any one time outstanding and (C) such
         indebtedness is not discharged, or such acceleration is not rescinded
         or annulled within a period of 30 days after there has been given, by
         registered or certified mail, to the Company by the Trustee or to the
         Company and the Trustee by the Holders of at least 25% in principal
         amount of Outstanding Securities a written notice specifying such event
         of default and requiring the Company to cause such acceleration to be
         rescinded or annulled or to cause such indebtedness to be discharged
         and stating that such notice is a "Notice of Default" hereunder; or

              (6)   the entry by a court having jurisdiction in the premises of
         (A) a decree or order for relief in respect of the Company in an
         involuntary case or proceeding under any applicable Federal or state
         bankruptcy, insolvency, reorganization or other similar law or (B) a
         decree or order adjudging the Company a bankrupt or insolvent, or
         approving as properly filed a petition seeking reorganization,
         arrangement, adjustment or composition of or in respect of the Company
         under any applicable Federal or state law, or appointing a custodian,
         receiver, liquidator, assignee, trustee, sequestrator or other similar
         official of the Company or of any substantial part of its property, or

         continuance of any such decree or order for relief or any such other
         decree or order unstayed and in effect for a period of 60 consecutive
         days; or

              (7)   the commencement by the Company of a voluntary case or
         proceeding under any applicable Federal or state bankruptcy,
         insolvency, reorganization or other similar law or of any other case or
         proceeding to be adjudicated a bankrupt or insolvent, or the consent by
         it to the entry of a decree or order for relief in respect of the
         Company in an involuntary case or proceeding under any applicable
         Federal or state bankruptcy, insolvency, reorganization or other
         similar law or the consent by it to the commencement of any bankruptcy
         or insolvency case or proceeding against it, or the filing by it of a

         of such petition or to the appointment of or taking possession by a
         custodian, receiver, liquidator, assignee, trustee, sequestrator or
         other similar official of the Company or of any substantial part of its
         property, or the making by it of an assignment for the benefit of
         creditors, or the admission by it in writing of its inability to pay
         its debts generally as they become due; or




                                       37

<PAGE>   46
              (8)   any other Event of Default provided with respect to
         Securities of that series.

Section 502. ACCELERATION OF MATURITY: RESCISSION AND ANNULMENT.

         If an Event of Default with respect to Securities of any series at the
time Outstanding occurs and is continuing, then in every such case the Trustee
or the Holders of not less than 25% in principal amount of the Outstanding
Securities of that series may declare the principal amount (or, if any of the
Securities of that series are Original Issue Discount Securities or Indexed
Securities, such portion of the principal amount of such Securities as may be
specified in the terms thereof) of all of the Securities of that series to be
due and payable immediately, by a notice in writing to the Company (and to the
Trustee if given by Holders), and upon any such declaration such principal
amount (or, in the case of Original Issue Discount Securities or Indexed
Securities, such specified amount) shall become immediately due and payable.

         At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if

              (1)   the Company has paid or deposited with the Trustee a sum
         sufficient to pay

                    (A)   all overdue interest on all Securities of that series,

                    (B)   the principal of (and premium, if any, on) any
              Securities of that series which have become due otherwise than by
              such declaration of acceleration and any interest thereon at the
              rate or rates prescribed therefor in such Securities,

                    (C)   to the extent that payment of such interest is lawful,
              interest upon overdue interest at the rate or rates prescribed
              therefor in such Securities, and

                    (D)   all sums paid or advanced by the Trustee hereunder and
              the reasonable compensation, expenses, disbursements and advances
              of the Trustee, its agents and counsel;

         and




                                       38

<PAGE>   47
              (2)   all Events of Default with respect to Securities of that
         series, other than the non-payment of the principal of Securities of
         that series which have become due solely by such declaration of
         acceleration, have been cured or waived as provided in Section 513.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

Section 503. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

         The Company covenants that if

              (1)   default is made in the payment of any interest on any
         Security when such interest becomes due and payable and such default
         continues for a period of 30 days, or

              (2)   default is made in the payment of the principal of (or
         premium, if any, on) any Security at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal and any premium and interest and, to the extent that
payment of such interest shall be legally enforceable, interest on any overdue
principal and premium and on any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

         If an Event of Default with respect to Securities of any series occurs
and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of Securities of such series by
such appropriate judicial proceedings as the Trustee shall deem most effectual
to protect and enforce any such rights, whether for the specific enforcement of
any covenant or agreement in this Indenture or in aid of the exercise of any
power granted herein, or to enforce any other proper remedy.

Section 504. TRUSTEE MAY FILE PROOFS OF CLAIM.

         In case of any judicial proceeding relative to the Company (or any
other obligor upon the Securities), its property or its creditors, the Trustee
shall be entitled and empowered, by intervention in such proceeding or
otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such
proceeding. In particular, the Trustee shall be authorized to collect and
receive any moneys or other property payable or




                                       39

<PAGE>   48
deliverable on any such claims and to distribute the same; and any custodian,
receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Holder to make such

making of such payments directly to the Holders, to pay to the Trustee any
amount due it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 607.

         No provision of this Indenture shall be deemed to authorize the Trustee
to authorize or consent to or accept or adopt on behalf of any Holder any plan
of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding.

any such proceeding instituted by the Trustee shall be brought in its own name
as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

applied in the following order, at the date or dates fixed by the Trustee and,

              (1)   such Holder has previously given written notice to the
         Trustee of a continuing Event of Default with respect to the Securities
         of that series;

              (2)   the Holders of not less than 25% in principal amount of the
         Outstanding Securities of that series shall have made written request
         to the Trustee to institute proceedings in respect of such Event of
         Default in its own name as Trustee hereunder;

              (3)   such Holder or Holders have offered to the Trustee

         request and offer of indemnity has failed to institute any such
         proceeding; and

         given to the Trustee before or during such 60-day period by the Holders
         of a majority in principal amount of the Outstanding Securities of that
         series;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other
Holders, or to obtain or to seek to obtain priority or preference over any other
Holders or to enforce any right under this Indenture, except in the manner
herein provided and for the equal and ratable benefit of all Holders.

any interest on such Security on the Stated Maturity or Maturities expressed in
such Security (or, in the case of redemption, on the Redemption Date) and to
institute suit for the enforcement of any such payment, and such rights shall
not be impaired without the consent of such Holder.

         If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

conferred upon or reserved to the Trustee or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

Section 511. DELAY OR OMISSION NOT WAIVER.

         No delay or omission of the Trustee or of any Holder of any Securities
to exercise any right or remedy accruing upon any Event of Default shall impair

an acquiescence therein. Every right and remedy given by this Article or by law
to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.

Section 512. CONTROL BY HOLDERS.

         The Holders of a majority in principal amount of the Outstanding
Securities of any series shall 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
Securities of such series, provided that

              (1)   such direction shall not be in conflict with any rule of law
         or with this Indenture, and

         interest on any Security of such series, or

              (2)   in respect of a covenant or provision hereof which under
         Article Nine cannot be modified or amended without the consent of the
         Holder of each Outstanding Security of such series affected.

         Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

Section 514. UNDERTAKING FOR COSTS.

         In any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken, suffered or
omitted by it as Trustee, a court may require any party litigant in such suit to
file an undertaking to pay the costs of such suit, and may assess reasonable
costs, including reasonable counsel fees and expenses, against any such party
litigant, in the manner and to the extent provided in the Trust Indenture Act;
PROVIDED that neither this Section nor the Trust Indenture Act shall be deemed
to authorize any court to require such an undertaking or to make such an
assessment in any suit instituted by the Company, the Trustee or the Holders of
10% aggregate principal amount of the Outstanding Securities of any series.

Section 515. WAIVER OF USURY, STAY OR EXTENSION LAWS.

         The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any usury, stay or extension law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

Section 601. CERTAIN DUTIES AND RESPONSIBILITIES.

         The duties and responsibilities of the Trustee shall be as provided by
the Trust Indenture Act. Notwithstanding the foregoing, no provision of this
Indenture shall require the Trustee to expend or risk its own funds or otherwise
incur any financial liability in the performance of any of its duties hereunder,
or in the exercise of any of its rights or powers, if it shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against
such risk or liability is not reasonably assured to it. Whether or not therein
expressly so provided, every provision of this Indenture relating to the conduct
or affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section.

Section 602. NOTICE OF DEFAULTS.

shall be given until at least 90 days after the occurrence thereof, and provided
further that, except in the case of any defaults of the character specified in
clauses (1), (2) and (3) of Section 501, the Trustee may refrain from giving any
notice of default to the Holders of Securities if the Trustee considers it in
the interests of such Holders to so refrain. For the purpose of this Section,

         Holders shall have offered to the Trustee reasonable security or
         indemnity against the costs, expenses and liabilities which might be
         incurred by it in compliance with such request or direction;

              (f)   the Trustee shall not be bound to make any investigation
         into the facts or matters stated in any resolution, certificate,

         as it may see fit, and, if the Trustee shall determine to make such
         further inquiry or investigation, it shall be entitled to examine the
         books, records and premises of the Company, personally or by agent or

         Corporate Trust Office of the Trustee, and such notice references the
         Securities and this Indenture.

         The recitals contained herein and in the Securities, except the

act as trustee under other indentures under which other securities, or
certificates of interest or participation in other securities, of the Company

that is eligible pursuant to the Trust Indenture Act to act as such and has a
combined capital and surplus of at least $50,000,000 and an office in the
Borough of Manhattan, The City of New York at which at any particular time the

eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereinafter specified in this
Article.

Section 610. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

         (a)   No resignation or removal of the Trustee and appointment of a

applicable requirements of Section 611.

         (b)   The Trustee may resign at any time with respect to the Securities
of one or more series by giving written notice thereof to the Company. If the
instrument of acceptance by a successor Trustee required by Section 611 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

         (c)   The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of a majority in principal amount
of the Outstanding Securities of such series, delivered to the Trustee and to
the Company. If the instrument of acceptance by a successor Trustee required by
Section 611 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of removal, the Trustee being removed may petition any
court of competent jurisdiction for the appointment of a successor Trustee with
respect to the Securities of such series.

         (d)   If at any time:

               (1)   the Trustee shall fail to comply with Section 608 after
         written request therefor by the Company or by any Holder who has been a
         bona fide Holder of a Security for at least six months, or




                                       48


<PAGE>   57
               (2)   the Trustee shall cease to be eligible under Section 609
         and shall fail to resign after written request therefor by the Company
         or by any such Holder, or

               (3)   the Trustee shall become incapable of acting or shall be
         adjudged a bankrupt or insolvent or a receiver of the Trustee or of its
         property shall be appointed or any public officer shall take charge or
         control of the Trustee or of its property or affairs for the purpose of
         rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company by or pursuant to a Board Resolution may
remove the Trustee and appoint a successor Trustee with respect to all
Securities, or (ii) subject to Section 514, any Holder who has been a bona fide
Holder of a Security for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee with respect to all Securities and the appointment of a
successor Trustee or Trustees.

         (e)   If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, with
respect to the Securities of one or more series, the Company, by or pursuant to
a Board Resolution, shall promptly appoint a successor Trustee or Trustees with
respect to the Securities of that or those series (it being understood that any
such successor Trustee may be appointed with respect to the Securities of one or
more or all of such series and that at any time there shall be only one Trustee
with respect to the Securities of any particular series) and shall comply with
the applicable requirements of Section 611. If, within one year after such
resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee with respect to the Securities of any series shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment in accordance with the applicable requirements of Section
611, become the successor Trustee with respect to the Securities of such series
and to that extent supersede the successor Trustee appointed by the Company. If
no successor Trustee with respect to the Securities of any series shall have
been so appointed by the Company or the Holders and accepted appointment in the
manner required by Section 611, any Holder who has been a bona fide Holder of a
Security of such series for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the appointment of a successor Trustee with respect to the Securities of such
series.

         (f)   The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
to all Holders of Securities of such series in the manner provided in Section
106. Each notice shall




                                       49


<PAGE>   58
include the name of the successor Trustee with respect to the Securities of such
series and the address of its Corporate Trust Office.

Section 611. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

         (a)   In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on the request
of the Company or the successor Trustee, such retiring Trustee shall, upon
payment of its charges, execute and deliver an instrument transferring to such
successor Trustee all the rights, powers and trusts of the retiring Trustee and
shall duly assign, transfer and deliver to such successor Trustee all property
and money held by such retiring Trustee hereunder.

         (b)   In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (2)
if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust and that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee; and upon the execution and delivery of such supplemental
indenture the resignation or removal of the retiring Trustee shall become
effective to the extent provided therein and each such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates; but, on request of the Company or any successor Trustee, such
retiring Trustee shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder with
respect to the




                                       50

<PAGE>   59
Securities of that or those series to which the appointment of such successor
Trustee relates.

         (c)   Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in paragraph (a) and (b) of this Section, as the case may be.

         (d)   No successor Trustee shall accept its appointment unless at the
time of such acceptance such successor Trustee shall be qualified and eligible
under this Article.

Section 612. MERGER CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

         Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities shall have been authenticated,
but not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Securities so authenticated with the same effect
as if such successor Trustee had itself authenticated such Securities.

Section 613. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

         If and when the Trustee shall be or become a creditor of the Company
(or any other obligor upon the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).

Section 614. APPOINTMENT OF AUTHENTICATING AGENT.

         The Trustee may appoint an Authenticating Agent or Agents with respect
to one or more series of Securities which shall be authorized to act on behalf
of the Trustee to authenticate Securities of such series issued upon original
issue and upon exchange, registration of transfer or partial redemption thereof
or pursuant to Section 306, and Securities so authenticated shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of




                                       51

<PAGE>   60
authentication, such reference shall be deemed to include authentication and
delivery on behalf of the Trustee by an Authenticating Agent and a certificate
of authentication executed on behalf of the Trustee by an Authenticating Agent.
Each Authenticating Agent shall be acceptable to the Company and shall at all
times be a corporation organized and doing business under the laws of the United
States of America, any State thereof or the District of Columbia, authorized
under such laws to act as Authenticating Agent, and if not an Affiliate of the
Trustee, having a combined capital and surplus of not less than $50,000,000 and
subject to supervision or examination by Federal or state authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

         Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to all or substantially all the
corporate agency or corporate trust business of an Authenticating Agent, shall
continue to be an Authenticating Agent, provided such corporation shall be
otherwise eligible under this Section, without the execution or filing of any
paper or any further act on the part of the Trustee or the Authenticating Agent.

         An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall mail written notice of
such appointment by first-class mail, postage prepaid, to all Holders of
Securities of the series with respect to which such Authenticating Agent will
serve, as their names and addresses appear in the Security Register. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

         The Trustee agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section, and the
Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 607.

         If an appointment with respect to one or more series is made pursuant
to this Section, the Securities of such series may have endorsed thereon, in
addition to or in lieu of the Trustee's certificate of authentication, an
alternative certificate of authentication in the following form:

         This is one of the Securities of the series designated therein referred
to in the within-mentioned Indenture.

         benefit of such series) or to surrender any right or power herein
         conferred upon the Company; or

               (3)   to add any additional Events of Default with respect to all

         such supplemental indenture and

<PAGE>   65
         entitled to the benefit of such provision nor (B) modify the rights of

         the States thereof and the District of Columbia), its territories, its
         possessions and other areas subject to its jurisdiction of principal
         of, or premium, if any, or interest, if any, on, securities in bearer
         form or coupons, if any; or

               (10)  to cure any ambiguity, to correct or supplement any
         provision herein which is mistaken or may be inconsistent with any
         other provision herein or to make any other provisions with respect to
         matters or questions arising under this Indenture, provided that such
         action pursuant to this clause (10), other than with respect to a
         mistaken provision, shall not adversely affect the interests of the
         Holders of Securities of any series in any material respect.

Section 902. SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS.

         With the consent of the Holders of not less than a majority in

by such supplemental indenture, by Act of said Holders delivered to the Company
and the Trustee, the Company, when authorized by a Board Resolution, and the
Trustee may enter into an indenture or indentures supplemental hereto for the

         installment of principal of or interest on, any Security, or reduce the
         principal amount

         Original Issue Discount Security that would be due and payable upon a
         declaration of acceleration of the Maturity thereof pursuant to Section
         502, or change any Place of Payment where, or the coin or currency in
         which, any Security or any premium or interest thereon is payable, or
         impair the right to institute suit for the enforcement of any such
         payment on or after the Stated Maturity thereof (or, in the case of
         redemption, on or after the Redemption Date), or adversely affect the
         right of the Holder of any Security to require the Company to
         repurchase such Security, or adversely affect the right to convert any
         Security as contemplated by Article Fourteen or modify the provisions
         of Article Thirteen or the definition of "Senior Debt" in a manner
         adverse to the Holder of any Security in any material respect, or

         consequences) provided for in this Indenture, or

               (3)   modify any of the provisions of this Section, Section 513
         or Section 1006, except to increase any percentage set forth in such
         Sections or to provide that certain other provisions of this Indenture
         cannot be modified or waived without the consent of the Holder of each
         Outstanding Security affected thereby; provided, however, that this
         clause shall not be deemed to require the consent of any Holder with
         respect to changes in the references to "the Trustee" and concomitant
         changes in this Section and Section 1006, or the deletion of this
         proviso, in accordance with the requirements of Sections 611(b) and
         901(8).

Section 903. EXECUTION OF SUPPLEMENTAL INDENTURES.

         In executing, or accepting the additional trusts created by, any

the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 601) shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such supplemental indenture is

Trustee's own rights, duties or immunities under this Indenture or otherwise.

Section 904. EFFECT OF SUPPLEMENTAL INDENTURES.

         Upon the execution of any supplemental indenture under this Article,

                                    Covenants

Section 1001. PAYMENT OF PRINCIPAL PREMIUM AND INTEREST.

         The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of and any premium
and interest on the Securities of that series in accordance with the terms of
such Securities and this Indenture.

Section 1002. MAINTENANCE OF OFFICE OR AGENCY.

         The Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange and where notices and demands to or
upon the Company in respect of the Securities of that series and this Indenture
may be served. The Company will give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency. If at any
time the Company shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee, and the Company hereby appoints the Trustee as its agent
to receive all such presentations, surrenders, notices and demands.

         The Company may also from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for any or all such purposes and may from time to time rescind
such designations; provided, however, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office
or agency in each Place of Payment for Securities of any series for such
purposes. The Company will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other
office or agency.

Section 1003. MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST.

         If the Company shall at any time act as its own Paying Agent with
respect to any series of Securities, it will, on or before each due date of the
principal of or any premium or interest on any of the Securities of that series,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay the principal and any premium and interest so becoming due
until such sums shall be paid to




                                       60

<PAGE>   69
such Persons or otherwise disposed of as herein provided and will promptly
notify the Trustee of its action or failure so to act.

         Whenever the Company shall have one or more Paying Agents for any
series of Securities, it will, prior to each due date of the principal of or any
premium or interest on any Securities of that series, deposit with a Paying
Agent a sum sufficient to pay such amount, such sum to be held as provided by
the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the
Company will promptly notify the Trustee of its action or failure so to act.

         The Company will cause each Paying Agent for any series of Securities
other than the Trustee to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section, that such Paying Agent will (i) comply with the provisions of
the Trust Indenture Act applicable to it as a Paying Agent and (ii) during the
continuance of any default by the Company (or any other obligor upon the
Securities of that series) in the making of any payment in respect of the
Securities of that series, and upon the written request of the Trustee,
forthwith pay to the Trustee all sums held in trust by such Paying Agent for
payment in respect of the Securities of that series.

         The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such money.

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of or any premium or
interest on any Security of any series and remaining unclaimed for two years
after such principal, premium or interest has become due and payable shall be
paid to the Company on Company Request, or (if then held by the Company) shall
be discharged from such trust; and the Holder of such Security shall thereafter,
as an unsecured general creditor, look only to the Company for payment thereof,
and all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, may at the expense of the Company cause to
be published once, in a newspaper published in the English language, customarily
published on each Business Day and of general circulation in The City of New
York, notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such publication,
any unclaimed balance of such




                                       61

money then remaining will be repaid to the Company free of the trust formerly
impressed upon it.

Company, stating whether or not to the best knowledge of the signers thereof the

         The Company may omit in any particular instance to comply with any
term, provision or condition set forth in Sections 801 and 1005, with respect to

Holders of at least a majority in principal amount of the Outstanding Securities
of such series shall, by Act of such Holders, either waive such compliance in
such instance or generally waive compliance with such term, provision or
condition, but no such waiver shall extend to or affect such term, provision or
condition except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Company and the duties of the Trustee
in respect of any such term, provision or condition shall remain in full force
and effect.

Section 1007. CALCULATION OF ORIGINAL ISSUE DISCOUNT.

         If the Trustee is requested or required to send Form 1099 (or any

Section 1101. APPLICABILITY OF ARTICLE.

         Securities of any series which are redeemable in whole or in part

and (except as otherwise specified as contemplated by Section 301 for Securities
of any series) in accordance with this Article.

Section 1102. ELECTION TO REDEEM: NOTICE TO TRUSTEE.

         The election of the Company to redeem any Securities shall be evidenced
by or pursuant to a Board Resolution or Officers' Certificate. In case of any

Company (unless a shorter notice shall be satisfactory to the Trustee), notify
the Trustee of such Redemption Date, of the principal amount of Securities of
such series to be redeemed and, if applicable, of the tenor of the Securities to

Officers' Certificate evidencing compliance with such restriction.

Section 1103. SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

         If less than all the Securities of any series are to be redeemed

redeemed), the particular Securities to be redeemed shall be selected not more
than 60 days prior to the Redemption Date by the Trustee, from the Outstanding
Securities of such series not previously called for redemption, by such method
as the Trustee shall deem fair and appropriate and which may provide for the
selection for redemption a portion of the principal amount of any Security of
such series, provided that the unredeemed portion of the principal amount of any
Security shall be in an authorized denomination (which shall not be less than
the minimum authorized denomination or any integral multiple thereof) for such
Security. If less than all of the Securities of such series and of a specified
tenor are to be redeemed, the particular Securities to be redeemed shall be
selected not more than 60 days prior to the Redemption Date by the Trustee, from
the Outstanding Securities of such series and specified tenor not previously
called for redemption in accordance with the preceding sentence.

         The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption and, in the case of any Securities selected
for partial redemption, the principal amount thereof to be redeemed.

redeemed.

Section 1104. NOTICE OF REDEMPTION.

         Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption

               (1)   the Redemption Date,

               (2)   the Redemption Price,

               (3)   if less than all the Outstanding Securities of any series

         redemption of any Securities, the principal amounts) of the particular
         Securities to be redeemed,

               (4)   that on the Redemption Date the Redemption Price will
         become due and payable upon each such Security, or portion thereof, to
         be redeemed and, if applicable, that interest thereon will cease to
         accrue on and after said date,

               (5)   the place or places where such Securities are to be
         surrendered for payment of the Redemption Price,

               (6)   that the redemption is for a sinking fund, if such is the
         case, and

               (7)   that there exists a conversion privilege, if applicable.

Section 1105. DEPOSIT OF REDEMPTION PRICE.

         Prior to 12:00 noon New York City time on any Redemption Date, the
Company shall deposit with the Trustee or with a Paying Agent (or, if the
Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 1003) an amount of money in the currency or currencies in
which the




                                       64

<PAGE>   73
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series) sufficient to pay the Redemption
Price of, and (except if the Redemption Date shall be an Interest Payment Date)
accrued interest on, all the Securities or portions thereof which are to be
redeemed on that date.

Section 1106. SECURITIES PAYABLE ON REDEMPTION DATE.

         Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption Price, together with accrued interest
to the Redemption Date; provided, however, that, unless otherwise specified as
contemplated by Section 301, installments of interest whose Stated Maturity is
on or prior to the Redemption Date shall be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 307.

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal and any premium shall, until
paid, bear interest from the Redemption Date at the rate prescribed therefor in
the Security.

Section 1107. SECURITIES REDEEMED IN PART.

         Any Security which is to be redeemed only in part shall be surrendered
at a Place of Payment therefor (with, if the Company or the Trustee so requires,
due endorsement by, or a written instrument of transfer in form satisfactory to
the Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and deliver or make available for delivery to the Holder of
such Security without service charge, a new Security or Securities of the same
series and of like tenor, of any authorized denomination as requested by such
Holder, in aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Security so surrendered.

                                  Sinking Funds

Section 1201. APPLICABILITY OF ARTICLE.

         The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of a series except as otherwise specified as
contemplated by Section 301 for Securities of such series.

         The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment", and any payment in excess of such minimum amount provided for by
the terms of Securities of any series is herein referred to as an "optional
sinking fund payment". If provided for by the terms of Securities of any series,
the cash amount of any sinking fund payment may be subject to reduction as
provided in Section 1202. Each sinking fund payment shall be applied to the
redemption of Securities of any series as provided for by the terms of
Securities of such series.

Section 1202. SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

         The Company (1) may deliver Outstanding Securities of a series (other
than any previously called for redemption) and (2) may apply as a credit
Securities of a series which have been (a) redeemed either at the election of
the Company pursuant to the terms of such Securities or through the application
of permitted optional sinking fund payments pursuant to the terms of such
Securities, (b) converted pursuant to Article Fourteen or (c) cancelled or
delivered for cancellation pursuant to Section 309, in each case in satisfaction
of all or any part of any sinking fund payment with respect to the Securities of
such series required to be made pursuant to the terms of such Securities as
provided for by the terms of such series; provided that such Securities have not
been previously so credited. Such Securities shall be received and credited for
such purpose by the Trustee at the Redemption Price specified in such Securities
for redemption through operation of the sinking fund and the amount of such
sinking fund payment shall be reduced accordingly.

Section 1203. REDEMPTION OF SECURITIES FOR SINKING FUND.

         Not less than 45 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
that series pursuant to the terms of that series, the portion thereof, if any,
which is to be satisfied by payment of cash and the portion thereof, if any,
which is to be satisfied by delivering and crediting Securities of that series
pursuant to Section 1202 and will also deliver to the Trustee any Securities to
be so delivered. Not less than 30 days before each such sinking fund payment
date the Trustee shall select the Securities to




                                       66

<PAGE>   75
be redeemed upon such sinking fund payment date in the manner specified in
Section 1103 and cause notice of the redemption thereof to be given in the name
of and at the expense of the Company in the manner provided in Section 1104.
Such notice having been duly given, the redemption of such Securities shall be
made upon the terms and in the manner stated in Sections 1106 and 1107.

                           Subordination of Securities

Section 1301. SECURITIES SUBORDINATE TO SENIOR DEBT.

         The Company covenants and agrees, and each Holder of a Security, by his
acceptance thereof, likewise covenants and agrees, that, to the extent and in
the manner hereinafter set forth in this Article (subject to the provisions of
Article Four and Article Fifteen), the payment of the principal of (and premium,
if any) and interest on each and all of the Securities (including any amounts
payable upon a purchase of the Securities) are hereby expressly made subordinate
and subject in right of payment to the prior payment in full of all Senior Debt.

Section 1302. PAYMENT OVER OF PROCEEDS UPON DISSOLUTION, ETC.

         In the event of (a) any insolvency or bankruptcy case or proceeding, or
any receivership, liquidation, reorganization or other similar case or
proceeding in connection therewith, relative to the Company or to its creditors,
as such, or to its assets, or (b) any liquidation, dissolution or other winding
up of the Company, whether voluntary or involuntary and whether or not involving
insolvency or bankruptcy, or (c) any assignment for the benefit of creditors or
any other marshalling of assets and liabilities of the Company, then and in any
such event specified in (a), (b) or (c) above (each such event, if any, herein
sometimes referred to as a "Proceeding") the holders of Senior Debt shall be
entitled to receive payment in full of all amounts due or to become due on or in
respect of all Senior Debt, or provision shall be made for such payment in cash
or cash equivalents or otherwise in a manner satisfactory to the holders of
Senior Debt, before the Holders of the Securities are entitled to receive any
payment or distribution of any kind or character, whether in cash, property or
securities, on account of principal of (or premium, if any) or interest on or
other obligations in respect of the Securities or on account of any purchase or
other acquisition of Securities by the Company or any Subsidiary of the Company
(all such payments, distributions, purchases and acquisitions herein referred
to, individually and collectively, as a "Securities Payment"), and to that end
the holders of Senior Debt shall be entitled to receive, for application to the
payment thereof, any Securities Payment which may be payable or deliverable in
respect of the Securities in any such Proceeding.




                                       67

<PAGE>   76
         In the event that, notwithstanding the foregoing provisions of this
Section, the Trustee or the Holder of any Security shall have received any
Securities Payment before all Senior Debt is paid in full or payment thereof
provided for in cash or cash equivalents or otherwise in a manner satisfactory
to the holders of Senior Debt, and if such fact shall, at or prior to the time
of such Securities Payment, have been made known to the Trustee or, as the case
may be, such Holder, then and in such event such Securities Payment shall be
paid over or delivered forthwith to the trustee in bankruptcy, receiver,
liquidating trustee, custodian, assignee, agent or other Person making payment
or distribution of assets of the Company for application to the payment of all
Senior Debt remaining unpaid, to the extent necessary to pay all Senior Debt in
full, after giving effect to any concurrent payment or distribution to or for
the holders of Senior Debt.

         For purposes of this Article only, the words "any payment or
distribution of any kind or character, whether in cash, property or securities"
shall not be deemed to include a payment or distribution of stock or securities
of the Company provided for by a plan of reorganization or readjustment
authorized by an order or decree of a court of competent jurisdiction in a
reorganization proceeding under any applicable bankruptcy law or of any other
corporation provided for by such plan of reorganization or readjustment which
stock or securities are subordinated in right of payment to all then outstanding
Senior Debt to substantially the same extent as the Securities are so
subordinated as provided in this Article. The consolidation of the Company with,
or the merger of the Company into, another Person or the liquidation or
dissolution of the Company following the conveyance or transfer of all or
substantially all of its properties and assets as an entirety to another Person
upon the terms and conditions set forth in Article Eight shall not be deemed a
Proceeding for the purposes of this Section if the Person formed by such
consolidation or into which the Company is merged or the Person which acquires
by conveyance or transfer such properties and assets as an entirety, as the case
may be, shall, as a part of such consolidation, merger, conveyance or transfer,
comply with the conditions set forth in Article Eight.

Section 1303. NO PAYMENT WHEN SENIOR DEBT IN DEFAULT.

         In the event that any Securities are declared due and payable before
their Stated Maturity, then in such event the holders of the Senior Debt
outstanding at the time such Securities become due and payable shall be entitled
to receive payment in full of all amounts due or to become due on or in respect
of all Senior Debt, or provision shall be made for such payment in cash or cash
equivalents or otherwise in a manner satisfactory to the holders of such Senior
Debt, before the Holders of the Securities are entitled to receive any
Securities Payment.

         In the event and during the continuation of any default in the payment
of principal of (or premium, if any) or interest on any Senior Debt beyond any




                                       68

<PAGE>   77
applicable grace period with respect thereto, or in the event that any event of
default with respect to any Senior Debt shall have occurred and be continuing
permitting the holders of such Senior Debt (or a trustee on behalf of the
holders thereof) to declare such Senior Debt due and payable prior to the date
on which it would otherwise have become due and payable, unless and until such
event of default shall have been cured or waived or shall have ceased to exist
and such acceleration shall have been rescinded or annulled, or in the event any
judicial proceeding shall be pending with respect to any such default in payment
or event of default, then no Securities Payment shall be made; provided,
however, that nothing in this paragraph shall prevent the satisfaction of any
sinking fund payment in accordance with Article Twelve by delivering and
crediting pursuant to Section 1202 Securities which have been acquired (upon
redemption or otherwise).

         In the event that, notwithstanding the foregoing, the Company shall
make any Securities Payment to the Trustee or any Holder prohibited by the
foregoing provisions of this Section, and if such fact shall, at or prior to the
time of such Securities Payment, have been made known to the Trustee or, as the
case may be, such Holder, then and in such event such Securities Payment shall
be paid over and delivered forthwith to the Company.

         The provisions of this Section shall not apply to any Securities
Payment with respect to which Section 1302 would be applicable.

Section 1304. PAYMENT PERMITTED IF NO DEFAULT.

         Nothing contained in this Article or elsewhere in this Indenture or in
any of the Securities shall prevent (a) the Company, at any time except during
the pendency of any Proceeding referred to in Section 1302 or under the
conditions described in Section 1303, from making Securities Payments, or (b)
the application by the Trustee of any money deposited with it hereunder to
Securities Payments or the retention of such Securities Payment by the Holders,
if, at the time of such application by the Trustee, it did not have knowledge
that such Securities Payment would have been prohibited by the provisions of
this Article.

Section 1305. SUBROGATION TO RIGHTS OF HOLDERS OF SENIOR DEBT.

         Subject to the payment in full of all amounts due or to become due on
or in respect of Senior Debt, or the provision for such payment in cash or cash
equivalents or otherwise in a manner satisfactory to the holders of Senior Debt,
the Holders of the Securities shall be subrogated to the rights of the holders
of such Senior Debt to receive payments and distributions of cash, property and
securities applicable to the Senior Debt until the principal of (and premium, if
any) and interest on the Securities shall be paid in full. For purposes of such
subrogation, no payments or distributions to the holders of the Senior Debt of
any cash, property or securities to which the




                                       69

<PAGE>   78
Holders of the Securities or the Trustee would be entitled except for the
provisions of this Article, and no payments over pursuant to the provisions of
this Article to the holders of Senior Debt by Holders of the Securities or the
Trustee, shall, as among the Company, its creditors other than holders of Senior
Debt and the Holders of the Securities, be deemed to be a payment or
distribution by the Company to or on account of the Senior Debt.

Section 1306. PROVISIONS SOLELY TO DEFINE RELATIVE RIGHTS.

         The provisions of this Article are and are intended solely for the
purpose of defining the relative rights of the Holders on the one hand and the
holders of Senior Debt on the other hand. Nothing contained in this Article or
elsewhere in this Indenture or in the Securities is intended to or shall (a)
impair, as among the Company, its creditors other than holders of Senior Debt
and the Holders of the Securities, the obligation of the Company, which is
absolute and unconditional (and which, subject to the rights under this Article
of the holders of Senior Debt, is intended to rank equally with all other
general obligations of the Company), to pay to the Holders of the Securities the
principal of (and premium, if any) and interest on the Securities as and when
the same shall become due and payable in accordance with their terms; or (b)
affect the relative rights against the Company of the Holders of the Securities
and creditors of the Company other than the holders of Senior Debt; or (c)
prevent the Trustee or the Holder of any Security from exercising all remedies
otherwise permitted by applicable law upon default under this Indenture, subject
to the rights, if any, under this Article of the holders of Senior Debt to
receive cash, property and securities otherwise payable or deliverable to the
Trustee or such Holder.

Section 1307. TRUSTEE TO EFFECTUATE SUBORDINATION.

         Each Holder of a Security by his acceptance thereof authorizes and
directs the Trustee on his behalf to take such action as may be necessary or
appropriate to effectuate the subordination provided in this Article and
appoints the Trustee his attorney-in-fact for any and all such purposes.

Section 1308. NO WAIVER OF SUBORDINATION PROVISIONS.

         No right of any present or future holder of any Senior Debt to enforce
subordination as herein provided shall at any time in any way be prejudiced or
impaired by any act or failure to act on the part of the Company or by any act
or failure to act, in good faith, by any such holder, or by any noncompliance by
the Company with the terms, provisions and covenants of this Indenture,
regardless of any knowledge thereof any such holder may have or be otherwise
charged with.




                                       70

<PAGE>   79
         Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Debt may, at any time and from time to time, without the
consent of or notice to the Trustee or the Holders of the Securities, without
incurring responsibility to the Holders of the Securities and without impairing
or releasing the subordination provided in this Article or the obligations
hereunder of the Holders of the Securities to the holders of Senior Debt, do any
one or more of the following: (i) change the manner, place or terms of payment
or extend the time of payment of, or renew or alter, Senior Debt, or otherwise
amend or supplement in any manner Senior Debt or any instrument evidencing the
same or any agreement under which Senior Debt is outstanding; (ii) sell,
exchange, release or otherwise deal with any property pledged, mortgaged or
otherwise securing Senior Debt; (iii) release any Person liable in any manner
for the collection of Senior Debt; and (iv) exercise or refrain from exercising
any rights against the Company and any other Person.

Section 1309. NOTICE TO TRUSTEE.

         The Company shall give prompt written notice to the Trustee of any fact
known to the Company which would prohibit the making of any payment to or by the
Trustee in respect of the Securities. Notwithstanding the provisions of this
Article or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any payment to or by the Trustee in respect of the Securities, unless
and until the Trustee shall have received written notice thereof from the
Company or a holder of Senior Debt or from any trustee therefor; and, prior to
the receipt of any such written notice, the Trustee, subject to the provisions
of Section 601, shall be entitled in all respects to assume that no such facts
exist; provided, however, that if the Trustee shall not have received the notice
provided for in this Section at least two Business Days prior to the date upon
which by the terms hereof any money may become payable for any purpose
(including, without limitation, the payment of the principal of (and premium, if
any) or interest on any Security), then, anything herein contained to the
contrary notwithstanding, the Trustee shall have full power and authority to
receive such money and to apply the same to the purpose for which such money was
received and shall not be affected by any notice to the contrary which may be
received by it within two Business Days prior to such date.

         Subject to the provisions of Section 601, the Trustee shall be entitled
to rely on the delivery to it of a written notice by a Person representing
himself to be a holder of Senior Debt (or a trustee therefor) to establish that
such notice has been given by a holder of Senior Debt (or a trustee therefor).
In the event that the Trustee determines in good faith that further evidence is
required with respect to the right of any Person as a holder of Senior Debt to
participate in any payment or distribution pursuant to this Article, the Trustee
may request such Person to furnish evidence to the reasonable satisfaction of
the Trustee as to the amount of Senior Debt held by such Person, the extent to
which such Person is entitled to participate in such payment or



                                       71

<PAGE>   80
distribution and any other facts pertinent to the rights of such Person under
this Article, and if such evidence is not furnished, the Trustee may defer any
payment to such Person pending judicial determination as to the right of such
Person to receive such payment.

Section 1310. RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF LIQUIDATING AGENT.

         Upon any payment or distribution of assets of the Company referred to
in this Article, the Trustee, subject to the provisions of Section 601, and the
Holders of the Securities shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which such Proceeding is
pending, or a certificate of the trustee in bankruptcy, receiver, liquidating
trustee, custodian, assignee for the benefit of creditors, agent or other Person
making such payment or distribution, delivered to the Trustee or to the Holders
of Securities, for the purpose of ascertaining the Persons entitled to
participate in such payment or distribution, the holders of the Senior Debt and
other indebtedness of the Company, the amount thereof or payable thereon, the
amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article.

Section 1311. TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR DEBT.

         The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Debt and shall not be liable to any such holders if it shall
in good faith mistakenly pay over or distribute to Holders of Securities or to
the Company or to any other Person cash, property or securities to which any
holders of Senior Debt shall be entitled by virtue of this Article or otherwise.

Section 1312. RIGHTS OF TRUSTEE AS HOLDER OF SENIOR DEBT; PRESERVATION OF
              TRUSTEE'S RIGHTS.

         The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article with respect to any Senior Debt which may at
any time be held by it, to the same extent as any other holder of Senior Debt,
and nothing in this Indenture shall deprive the Trustee of any of its rights as
such holder.

         Nothing in this Article shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 607.

Section 1313. ARTICLE APPLICABLE TO PAYING AGENTS.

         In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article shall in such case (unless the context otherwise
requires) be construed as extending to and including such Paying Agent within
its meaning as fully for all




                                       72

intents and purposes as if such Paying Agent were named in this Article in
addition to or in place of the Trustee; provided, however, that Section 1312
shall not apply to the Company or any Affiliate of the Company if it or such
Affiliate acts as Paying Agent.

Section 1314. DEFEASANCE OF THIS ARTICLE THIRTEEN.

         The subordination of the Securities provided by this Article Thirteen
is expressly made subject to the provisions for defeasance or covenant
defeasance in Article Fifteen hereof and, anything herein to the contrary
notwithstanding, upon the effectiveness of any such defeasance or covenant
defeasance, the Securities then outstanding shall thereupon cease to be
subordinated pursuant to this Article Thirteen.

                            Conversion of Securities

Section 1401. APPLICABILITY OF ARTICLE.

         If pursuant to Section 301 provision is made for the conversion of
Securities pursuant to this Article Fourteen, then the provisions of this
Article Fourteen, with such modifications thereto as may be specified pursuant
to Section 301 with respect to any Securities, shall be applicable to the
Securities of such series.

Section 1402. CONVERSION PRIVILEGE AND CONVERSION PRICE.

         Subject to and upon compliance with the provisions of this Article, at
the option of the Holder thereof, any Security or any portion of the principal
amount thereof which is $1,000 or an integral multiple of $1,000 may be
converted at the principal amount thereof, or of such portion thereof, into
fully paid and nonassessable shares (calculated as to each conversion to the
nearest 1/100 of a share) of Common Stock of the Company, at the conversion
price, determined as hereinafter provided, in effect at the time of conversion.
Such conversion right shall commence at the opening of business on the date
provided for in the Securities with respect to such Securities and expire at the
close of business on the date provided for in the Securities with respect to
such Securities. In case a Security or portion thereof is called for redemption,
such conversion right in respect of the Security or portion so called shall
expire at the close of business on the Business Day prior to the Redemption
Date, unless the Company defaults in making the payment due upon redemption.

         The price at which shares of Common Stock shall be delivered upon
conversion is herein referred to as the "conversion price". The conversion price
shall be adjusted in certain instances as provided in Section 1405.

Section 1403. EXERCISE OF CONVERSION PRIVILEGE.

         In order to exercise the conversion privilege, the Holder of any
Security to be converted shall surrender such Security, duly endorsed or
assigned to the Company or in blank, at any office or agency of the Company
maintained for that purpose pursuant to Section 1002, accompanied by written
notice to the Company at such office or agency that the Holder elects to convert
such Security or, if less than the entire principal amount thereof is to be
converted, the portion thereof to be converted. Securities surrendered for
conversion during the period from the close of business on any Regular Record
Date next preceding any Interest Payment Date to the opening of business on such
Interest Payment Date shall (except in the case of Securities or portions
thereof which have been called for redemption on a Redemption Date within such
period) be accompanied by payment in immediately available funds or other funds
acceptable to the Company of an amount equal to the interest payable on such
Interest Payment Date on the principal amount of Securities being surrendered
for conversion. Except as provided in the preceding sentence and subject to the
third paragraph of Section 307, no payment or adjustment shall be made upon any
conversion on account of any interest accrued on the Securities surrendered for
conversion or on account of any dividends on the Common Stock issued upon
conversion.

         Securities shall be deemed to have been converted immediately prior to
the close of business on the day of surrender of such Securities for conversion
in accordance with the foregoing provisions, and at such time the rights of the
Holders of such Securities as Holders shall cease, and the Person or Persons
entitled to receive the Common Stock issuable upon conversion shall be treated
for all purposes as the record holder or holders of such Common Stock at such
time. As promptly as practicable on or after the conversion date, the Company
shall issue and shall deliver at such office or agency a certificate or
certificates for the number of full shares of Common Stock issuable upon
conversion, together with payment in lieu of any fraction of a share, as
provided in Section 1404.

         In the case of any Security which is converted in part only, upon such
conversion the Company shall execute and the Trustee shall authenticate and
deliver to the Holder thereof, at the expense of the Company, a new Security or
Securities of authorized denominations in aggregate principal amount equal to
the unconverted portion of the principal amount of such Security.

Section 1404. FRACTIONS OF SHARES.

         No fractional shares of Common Stock shall be issued upon conversion of
Securities. If more than one Security shall be surrendered for conversion at one
time by the same Holder, the number of full shares which shall be issuable upon
conversion thereof shall be computed on the basis of the aggregate principal
amount




                                       74

<PAGE>   83
of the Securities (or specified portions thereof) so surrendered. Instead of any
fractional share of Common Stock which would otherwise be issuable upon
conversion of any Security or Securities (or specified portions thereof), the
Company shall pay a cash adjustment in respect of such fraction in an amount
equal to the same fraction of the market price per share of Common Stock (as
determined by the Board of Directors or in any manner prescribed by the Board of
Directors) at the close of business on the day of conversion.

Section 1405. ADJUSTMENT OF CONVERSION PRICE.

               (1)   In case at any time after the date of the issuance of the
         applicable Securities, the Company shall pay or make a dividend or
         other distribution on any class of capital stock of the Company in
         Common Stock, the conversion price in effect at the opening of business
         on the day following the date fixed for the determination of
         stockholders entitled to receive such dividend or other distribution
         shall be reduced by multiplying such conversion price by a fraction of
         which the numerator shall be the number of shares of Common Stock
         outstanding at the close of business on the date fixed for such
         determination and the denominator shall be the sum of such number of
         shares and the total number of shares constituting such dividend or
         other distribution, such reduction to become effective immediately
         after the opening of business on the day following the date fixed for
         such determination. For the purposes of this paragraph (1), the number
         of shares of Common Stock at any time outstanding shall not include
         shares held in the treasury of the Company but shall include shares
         issuable in respect of scrip certificates issued in lieu of fractions
         of shares of Common Stock. The Company will not pay any dividend or
         make any distribution on shares of Common Stock held in the treasury of
         the Company.

               (2)   In case at any time after the date of the issuance of the
         applicable Securities, the Company shall issue rights or warrants to
         all holders of its Common Stock (not being available on an equivalent
         basis to Holders of the Securities upon conversion) entitling them to
         subscribe for or purchase shares of Common Stock at a price per share
         less than the current market price per share (determined as provided in
         paragraph (8) of this Section) of the Common Stock on the date fixed
         for the determination of stockholders entitled to receive such rights,
         options or warrants (other than pursuant to a dividend reinvestment
         plan), the conversion price in effect at the opening of business on the
         day following the date fixed for such determination shall be reduced by
         multiplying such conversion price by a fraction of which the numerator
         shall be the number of shares of Common Stock outstanding at the close
         of business on the date fixed for such determination plus the number of
         shares of Common Stock which the aggregate of the offering price of the
         total number of shares of Common Stock so offered for subscription or
         purchase would




                                       75

<PAGE>   84
         purchase at such current market price and the denominator shall be the
         number of shares of Common Stock outstanding at the close of business
         on the date fixed for such determination plus the number of shares of
         Common Stock so offered for subscription or purchase, such reduction to
         become effective immediately after the opening of business on the day
         following the date fixed for such determination. For the purposes of
         this paragraph (2), the number of shares of Common Stock at any time
         outstanding shall not include shares held in the treasury of the
         Company but shall include shares issuable in respect of scrip
         certificates issued in lieu of fractions of shares of Common Stock. The
         Company will not issue any rights or warrants in respect of shares of
         Common Stock held in the treasury of the Company.

               (3)   In case at any time after the date of the issuance of the
         applicable Securities, outstanding shares of Common Stock shall be
         subdivided into a greater number of shares of Common Stock, the
         conversion price in effect at the opening of business on the day
         following the day upon which such subdivision becomes effective shall
         be proportionately reduced, and, conversely, in case outstanding shares
         of Common Stock shall each be combined into a smaller number of shares
         of Common Stock, the conversion price in effect at the opening of
         business on the day following the day upon which such combination
         becomes effective shall be proportionately increased, such reduction or
         increase, as the case may be, to become effective immediately after the
         opening of business on the day following the day upon which such
         subdivision or combination becomes effective.

               (4)   In case at any time after the date of the issuance of the
         applicable Securities, the Company shall, by dividend or otherwise,
         distribute to all holders of its Common Stock evidences of its
         indebtedness or assets (including securities, but excluding any rights
         or warrants referred to in paragraph (2) of this Section, any dividend
         or distribution paid in cash out of the retained earnings of the
         Company and any dividend or distribution referred to in paragraph (1)
         of this Section), the conversion price shall be adjusted so that the
         same shall equal the price determined by multiplying the conversion
         price in effect immediately prior to the close of business on the date
         fixed for the determination of stockholders entitled to receive such
         distribution by a fraction of which the numerator shall be the current
         market price per share (determined as provided in paragraph (8) of this
         Section) of the Common Stock on the date fixed for such determination
         less the then fair market value (as determined by the Board of
         Directors, whose determination shall be conclusive and described in a
         Board Resolution filed with the Trustee) of the portion of the assets
         or evidences of indebtedness so distributed applicable to one share of
         Common Stock and the denominator shall be such current market price per
         share of the Common Stock, such adjustment to become effective




                                       76

<PAGE>   85
         immediately prior to the opening of business on the day following the
         date fixed for the determination of stockholders entitled to receive
         such distribution.


               (5) In case at any time after the date of the issuance of the
         applicable Securities, the Company shall, by dividend or otherwise,
         distribute to all holders of its Common Stock cash (excluding any cash
         that is distributed upon a merger or consolidation to which Section
         1412 applies or as part of a distribution referred to in paragraph (4)
         of this Section) in an aggregate amount that, combined together with:

               (A)  the aggregate amount of any other distributions to all
                    holders of its Common Stock made exclusively in cash
                    within the 12 months preceding the date of payment of such
                    distribution and in respect of which no adjustment pursuant
                    to this paragraph (5) has been made, and

               (B)  the aggregate of any cash plus the fair market value (as
                    determined by the Board of Directors, whose determination
                    shall be conclusive and described in a Board Resolution) of
                    consideration payable in respect of any tender offer by the
                    Company or any of its subsidiaries for all or any portion of
                    the Common Stock concluded within the 12 months preceding
                    the date of payment of such distribution and in respect of
                    which no adjustment pursuant to paragraph (6) of this
                    Section has been made,

          (the amount of such cash distribution together with the amounts
          described in clauses (A) and (B) above being referred to herein as the
          "Aggregate Cash Distribution Amount") exceeds 15% of the product of
          (I) the current market price per share of the Common Stock on the date
          for the determination of holders of shares of Common Stock entitled to
          receive such distribution, times (II) the number of shares of Common
          Stock outstanding on such date (the amount by which the Aggregate Cash
          Distribution Amount exceeds 15% of the product of the amounts
          described in clauses (I) and (II) above being referred to herein as
          the "Excess Amount"), then, and in each such case, immediately after
          the close of business on such date for determination, the conversion
          price shall be decreased in accordance with the following formula:

                            M - (EA/O)
               AC = CP x ----------------      
                                 M

Where:

               AC = the adjusted conversion price.

               CP = the conversion price in effect immediately prior to the
                    close of business on the date fixed for determination of the
                    stockholders entitled to receive the distribution.

                M = the current market price per share (determined as provided
                    in paragraph (8) of this Section) of the Common Stock on the
                    date fixed for determination of the stockholders entitled to
                    receive the distribution.

               EA = the Excess Amount.

                O = the number of shares of Common Stock outstanding on the date
                    fixed for determination of the stockholders entitled to 
                    receive the distribution.


               (6)  In case at any time after the date of the issuance of the
          applicable Securities, a tender offer made by the Company or any
          Subsidiary for all or any portion of the Common Stock shall expire and
          such tender offer (as amended upon the expiration thereof) shall
          require the payment to stockholders (based on the acceptance (up to
          any maximum specified in the terms of the tender offer) of Purchased
          Shares (as defined below)) of an aggregate consideration having a fair
          market value (as determined by the Board of Directors, whose
          determination shall be conclusive and described in a Board Resolution)
          that combined together with:

               (A)  the aggregate of the cash plus the fair market value (as
                    determined by the Board of Directors, whose determination
                    shall be conclusive and described in a Board Resolution), as
                    of the expiration of such tender offer, of consideration
                    payable in respect of any other tender offer, by the Company
                    or any Subsidiary for all or any portion of the Common Stock
                    expiring within the 12 months preceding the expiration of
                    such tender offer and in respect of which no adjustment
                    pursuant to this paragraph (6) has been made, and

               (B)  the aggregate amount of any distributions to all holders of
                    the Company's Common Stock made exclusively in cash within
                    12 months preceding the expiration of such tender offer and
                    in respect of which no adjustment pursuant to paragraph (5)
                    of this Section has been made,

          exceeds 15% of the product of (I) the current market price per share
          of the Common Stock (determined as provided in paragraph (8) of this
          Section) as of the last time (the "Expiration Time") tenders could
          have been made pursuant to such tender offer (as it may be amended),
          times (II) the number of shares of Common Stock outstanding (including
          any tendered shares) on the Expiration Time, then, and in each such
          case, immediately prior to the opening of business on the day after
          the date of the Expiration Time, the conversion price shall be
          adjusted in accordance with the following formula:

                                   (M x O) - C
                      AC = CP x  ---------------
                                   M x (O - TS)

Where:
                      AC = the adjusted conversion price.

                      CP = the conversion price immediately prior to close of 
                           business on the date of the Expiration Time.

                      M  = the current market price per share of the Common 
                           Stock (determined as provided in paragraph (8) of
                           this Section) on the date of the Expiration Time.

                      O  = the number of shares of Common Stock outstanding 
                           (including any tendered shares) on the Expiration
                           Time.

                      C  = the amount of cash plus the fair market value (as 
                           determined by the Board of Directors, whose
                           determination shall be conclusive and described in a
                           Board Resolution) of the aggregate consideration
                           payable to stockholders based on the acceptance (up
                           to any maximum specified in the terms of the tender
                           offer) of Purchased Shares (as defined below).

                      TS = the number of all shares validly tendered and not 
                           withdrawn as of the Expiration Time (the shares
                           deemed so accepted up to any such maximum, being
                           referred to as the "Purchased Shares").

               (7)   The reclassification of Common Stock into securities
         including securities other than Common Stock (other than any
         reclassification upon a consolidation or merger to which Section 1412
         applies) shall be deemed to involve (a) a distribution of such
         securities other than Common Stock to all holders of Common Stock (and
         the effective date of such reclassification shall be deemed to be "the
         date fixed for the determination of stockholders entitled to receive
         such distribution" and "the date fixed for such determination" within

         the meaning of paragraph (4) of this Section), and (b) a subdivision or
         combination, as the case may be, of the number of shares of Common
         Stock outstanding immediately prior to such reclassification into the
         number of shares of Common Stock outstanding immediately thereafter
         (and the effective date of such reclassification shall be deemed to be
         "the day upon which such subdivision becomes effective" or "the day
         upon which such combination becomes effective", as the case may be, and
         "the day upon which such subdivision or combination becomes effective"
         within the meaning of paragraph (3) of this Section).

               (8)   For the purpose of any computation under paragraphs (2),
         (4), (5) and (6) of this Section, the current market price per share of
         Common Stock on any date shall be deemed to be the average of the daily
         closing prices for the five consecutive Trading Days selected by the
         Company commencing not more than 20 Trading Days before, and ending not
         later than the earlier of the day in question and the day before the
         "ex" date with request to the issuance or distribution requiring such
         computation. The closing price for each day shall be the last reported
         sales price regular way or, in case no such reported sale takes place
         on such day, the average of the reported closing bid and asked prices
         regular way, in either case on the New York Stock Exchange or, if the
         Common Stock is not listed or admitted to trading on such Exchange, on
         the principal national securities exchange on which the Common Stock is
         listed or admitted to trading or, if not listed or admitted to trading
         on any national securities exchange, on the Nasdaq National Market or,
         if the Common Stock is not listed or admitted to trading on any
         national securities exchange or quoted on the Nasdaq National Market,
         the average of the closing bid and asked prices in the over-the-counter
         market as furnished by any New York Stock Exchange member firm selected
         from time to time by the Company for that purpose. For purposes of this
         paragraph, the term "'ex' date", when used with respect to any issuance
         or distribution, means the first date on which the Common Stock trades
         regular way on such exchange or in such market without the right to
         receive such issuance or distribution.

               (9)   No adjustment in the conversion price shall be required
         unless such adjustment (plus any adjustments not previously made by
         reason of this paragraph (9)) would require an increase or decrease of
         at least 1% in such price; provided, however, that any adjustments
         which by reason of this paragraph (9) are not required to be made shall
         be carried forward and taken into account in any subsequent adjustment.
         All calculations under this paragraph (9) shall be made to the nearest
         cent.

               (10)  The Company may make such reductions in the conversion
         price, in addition to those required by this Section, as it considers
         to be advisable in

         order to avoid or diminish any income tax to any holders of shares of
         Common Stock resulting from any dividend or distribution of stock or
         issuance of rights or warrants to purchase or subscribe for stock or
         from any event treated as such for income tax purposes or for any other
         reasons. The Company shall have the power to resolve any ambiguity or
         correct any error in this paragraph (10) and its actions in so doing
         shall be final and conclusive.

Section 1406. NOTICE OF ADJUSTMENTS OF CONVERSION PRICE.

         Whenever the conversion price is adjusted as herein provided:

         Certificate, one of the signatories of which shall be the Treasurer of 
         the Company, setting forth the adjusted conversion price and showing in
         reasonable detail the facts upon which such adjustment is based, and
         such certificate shall forthwith be filed at each office or agency
         maintained for the purpose of conversion of Securities pursuant to
         Section 1002; and

               (b)   a notice stating that the conversion price has been

         such notice shall be mailed by the Company to all Holders at their last
         addresses as they shall appear in the Security Register.

Section 1407. NOTICE OF CERTAIN CORPORATE ACTION.

         In case at any time after the date 20 days prior to the date on which
the Securities first become convertible:

               (a)   the Company shall declare a dividend (or any other
         distribution) on its Common Stock payable otherwise than in cash out of
         its retained earnings; or

               (b)   the Company shall authorize the granting to the holders of
         its Common Stock of rights or warrants to subscribe for or purchase any
         shares of capital stock of any class or of any other rights; or

               (c)   of any reclassification of the Common Stock of the Company
         (other than a subdivision or combination of its outstanding shares of
         Common Stock), or of any consolidation or merger to which the Company
         is a party and for which approval of any stockholders of the Company is
         required, or of the sale or transfer of all or substantially all of the
         assets of the Company; or




                                       80

<PAGE>   89
               (d)   of the voluntary or involuntary dissolution, liquidation or
         winding up of the Company;

then the Company shall cause to be filed at each office or agency maintained for
the purpose of conversion of Securities pursuant to Section 1002, and shall
cause to be mailed to all Holders at their last addresses as they shall appear
in the Security Register, at least 20 days (or 10 days in any case specified in
clause (a) or (b) above) prior to the applicable record or effective date
hereinafter specified, a notice stating (x) the date on which a record is to be
taken for the purpose of such dividend, distribution, rights or warrants, or, if
a record is not to be taken, the date as of which the holders of Common Stock of
record to be entitled to such dividend, distribution, rights or warrants are to
be determined, or (y) the date on which such reclassification, consolidation,
merger, share exchange, sale, transfer, dissolution, liquidation or winding up
is expected to become effective, and the date as of which it is expected that
holders of Common Stock of record shall be entitled to exchange their shares of
Common Stock for securities, cash or other property deliverable upon such
reclassification, consolidation, merger, share exchange, sale, transfer,
dissolution, liquidation or winding up. Neither the failure to give such notice
nor any defect therein shall affect the legality or validity of the proceedings
described in clauses (a) through (d) of this Section 1407. If at the time the
Trustee shall not be the conversion agent, a copy of such notice shall also
forthwith be filed by the Company with the Trustee.

Section 1408. COMPANY TO RESERVE COMMON STOCK.

         The Company shall at all times reserve and keep available, free from
preemptive rights, out of its authorized but unissued Common Stock, for the
purpose of effecting the conversion of Securities, the full number of shares of
Common Stock then issuable upon the conversion of all outstanding Securities.

Section 1409. TAXES ON CONVERSIONS.

         The Company will pay any and all taxes that may be payable in respect
of the issue or delivery of shares of Common Stock on conversion of Securities
pursuant hereto. The Company shall not, however, be required to pay any tax
which may be payable in respect of any transfer involved in the issue and
delivery of shares of Common Stock in a name other than that of the Holder of
the Security or Securities to be converted, and no such issue or delivery shall
be made unless and until the Person requesting such issue has paid to the
Company the amount of any such tax, or has established to the satisfaction of
the Company that such tax has been paid.

<PAGE>   90
Section 1410. COVENANT AS TO COMMON STOCK.

         The Company covenants that all shares of Common Stock which may be
issued upon conversion of Securities will upon issue be fully paid and
nonassessable and, except as provided in Section 1409, the Company will pay all
taxes, liens and charges with respect to the issue thereof.

Section 1411. CANCELLATION OF CONVERTED SECURITIES.

         All Securities delivered for conversion shall be delivered to the
Trustee to be cancelled by or at the direction of the Trustee, which shall
dispose of the same as provided in Section 309.

Section 1412. PROVISIONS IN CASE OF CONSOLIDATION, MERGER OR SALE OF ASSETS.

         In case of any consolidation of the Company with, or merger of the
Company into, any other Person, any merger of another Person into the Company
(other than a merger which does not result in any reclassification, conversion,
exchange or cancellation of outstanding shares of Common Stock of the Company)
or any sale or transfer of all or substantially all of the assets of the
Company, the Person formed by such consolidation or resulting from such merger
or which acquires such assets, as the case may be, shall execute and deliver to
the Trustee a supplemental indenture providing that the Holder of each Security
then outstanding shall have the right thereafter, during the period such
Security shall be convertible as specified in Section 1402, to convert such
Security only into the kind and amount of securities, cash and other property
receivable upon such consolidation, merger, sale or transfer by a holder of the
number of shares of Common Stock of the Company into which such Security might
have been converted immediately prior to such consolidation, merger, sale or
transfer, assuming such holder of Common Stock of the Company (i) is not a
Person with which the Company consolidated or into which the Company merged or
which merged into the Company or to which such sale or transfer was made, as the
case may be ("constituent Person"), or an Affiliate of a constituent Person and
(ii) failed to exercise his rights of election, if any, as to the kind or amount
of securities, cash and other property receivable upon such consolidation,
merger, sale or transfer (provided that if the kind or amount of securities,
cash and other property receivable upon such consolidation, merger, sale or
transfer is not the same for each share of Common Stock of the Company held
immediately prior to such consolidation, merger, sale or transfer by other than
a constituent Person or an Affiliate thereof and in respect of which such rights
of election shall not have been exercised ("non-electing share"), then for the
purpose of this Section the kind and amount of securities, cash and other
property receivable upon such consolidation, merger, sale or transfer by each
non-electing share shall be deemed to be the kind and amount so receivable per
share by a plurality of the non-electing shares), and assuming, if such
consolidation, merger, sale or transfer is prior to the date upon




                                       82


<PAGE>   91
which the Securities first become convertible, that the Securities were
convertible at the time of such consolidation, merger, sale or transfer at the
initial conversion price specified in Section 1402 as adjusted from the date of
the issuance of the applicable Securities to such time pursuant to Section 1405.
Such supplemental indenture shall provide for adjustments which, for events
subsequent to the effective date of such supplemental indenture, shall be as
nearly equivalent as may be practicable to the adjustments provided for in this
Article. The above provisions of this Section shall similarly apply to
successive consolidations, mergers, sales or transfers.

                                 ARTICLE FIFTEEN

                       Defeasance and Covenant Defeasance

Section 1501. APPLICABILITY OF ARTICLE; COMPANY'S OPTION TO EFFECT DEFEASANCE OR
COVENANT DEFEASANCE.

         Unless pursuant to Section 301 provision is made that either or both
(a) defeasance of the Securities of a series under Section 1502 or (b) covenant
defeasance of the Securities of a series under Section 1503 shall not be
applicable to the Securities of any series, then the provisions of such Section
or Sections, as the case may be, together with the other provisions of this
Article Fifteen, with such modifications thereto as may be specified pursuant to
Section 301 with respect to any Securities, shall be applicable to the
Securities of such series, and the Company may at its option by Board
Resolution, at any time, with respect to the Securities of such series, elect to
have either Section 1502 (if applicable) or Section 1503 (if applicable) applied
to the Outstanding Securities of such series upon compliance with the conditions
set forth below in this Article Fifteen.

Section 1502. DEFEASANCE AND DISCHARGE.

         Upon the Company's exercise of its option to have this Section applied
to any series of Securities the Company shall be deemed to have been discharged
from its obligations with respect to the Outstanding Securities of such series,
and the provisions of Article Thirteen hereof shall cease to be effective, on
and after the date the conditions precedent set forth below are satisfied
(hereinafter, "defeasance"). For this purpose, such defeasance means that the
Company shall be deemed to have paid and discharged the entire indebtedness
represented by and obligations under the Outstanding Securities of such series
which shall thereafter be deemed to be "Outstanding" only for the purposes of
the Sections of this Indenture referred to in clauses (A) and (B) of this
Section, and to have satisfied all its other obligations under such Securities
and this Indenture insofar as such Securities are concerned (and the Trustee, at
the expense of the Company, shall execute proper instruments acknowledging the
same), except for the following which shall survive until otherwise terminated
or discharged hereunder: (A) the rights of Holders of Outstanding Securities of
such series to receive, solely from the trust fund described in Section 1504 as
more fully set forth in such Section, payments of the principal of




                                       83


<PAGE>   92
(and premium, if any) and interest on such Securities when such payments are
due, and (B) the Company's obligations with respect to such Securities under
Sections 305, 306, 1002 and 1003 and such obligations as shall be ancillary
thereto. Subject to compliance with this Article Fifteen, the Company may
exercise its option under this Section 1502 notwithstanding the prior exercise
of its option under Section 1503 with respect to the Securities of such series.
Following a defeasance, payment of such Securities may not be accelerated
because of an Event of Default.

Section 1503. COVENANT DEFEASANCE.

         Upon the Company's exercise of its option (if any) to have this Section
applied to any series of Securities, the Company shall be released from its
obligations under Section 801 (and any covenant made applicable to such
Securities pursuant to Section 301), the occurrence of an event specified in
Sections 501(4) through 501(8) (and any other Event of Default applicable to
such Securities that are determined pursuant to Section 301 to be subject to
this provision) shall not be deemed to be an Event of Default with respect to
the Outstanding Securities of such series and the provisions of Article Thirteen
hereof shall cease to be effective on and after the date the conditions set
forth below are satisfied (hereinafter, "covenant defeasance"), and such
Securities shall thereafter be deemed not to be "Outstanding" for the purposes
of any direction, waiver, consent or declaration or Act of Holders (and the
consequences of any thereof) in connection with Section 801 (and any other
covenant made applicable to such Security pursuant to Section 301), but shall
continue to be deemed "Outstanding" for all other purposes hereunder. For this
purpose, such covenant defeasance means that, with respect to the Outstanding
Securities of such series, the Company may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
Section or such other covenant whether directly or indirectly by reason of any
reference elsewhere herein to any such Section or such other covenant or by
reason of any reference in any such Section or such other covenant to any other
provision herein or in any other document, but the remainder of this Indenture
and such Securities shall be unaffected thereby.

Section 1504. CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

         The following shall be the conditions precedent to application of
either Section 1502 or Section 1503 to the Outstanding Securities of or within
such series:

               (1)   The Company shall have deposited or caused to be deposited
         with the Trustee (or another trustee satisfying the requirements of
         Section 609 who shall agree to comply with the provisions of this
         Article Fifteen applicable to it) as trust funds in trust for the
         purpose of making the following payments, specifically pledged as
         security for, and dedicated solely to, the benefit of the Holders of
         such Securities, (A) money in an amount (in such currency, currencies
         or currency units in which such Securities are then specified as
         payable at Maturity), or (B) U.S. Government Obligations which through
         the scheduled payment of principal and interest in respect thereof in
         accordance with their terms will provide, not later than one day before
         the due date of



                                       84

<PAGE>   93
         any payment, money in an amount, or (C) a combination thereof in an
         amount, sufficient, in the opinion of a nationally recognized firm of
         independent public accountants expressed in a written certification
         thereof delivered to the Trustee, to pay and discharge, and which shall
         be applied by the Trustee (or other qualifying trustee) to pay and
         discharge, (i) the principal of (and premium, if any) and interest on
         the Outstanding Securities of such series on the Maturity of such
         principal, premium, if any, or interest and (ii) any mandatory sinking
         fund payments applicable to such Securities on the day on which such
         payments are due and payable in accordance with the terms of this
         Indenture and such Securities. Before such a deposit the Company may
         make arrangements satisfactory to the Trustee for the redemption of
         Securities at a future date or dates in accordance with Article Eleven,
         which shall be given effect in applying the foregoing. For this
         purpose, "U.S. Government Obligations" means securities that are (x)
         direct obligations of the United States of America for the payment of
         which its full faith and credit is pledged or (y) obligations of a
         Person controlled or supervised by and acting as an agency or
         instrumentality of the United States of America the payment of which is
         unconditionally guaranteed as a full faith and credit obligation by the
         United States of America, which, in either case, are not callable or
         redeemable at the option of the issuer thereof, and shall also include
         a depositary receipt issued by a bank (as defined in Section 3(a)(2) of
         the Securities Act of 1933, as amended) as custodian with respect to
         any such U.S. Government Obligation or a specific payment of principal
         of or interest on any such U.S. Government Obligation held by such
         custodian for the account of the holder of such depositary receipt,
         provided that (except as required by law) such custodian is not
         authorized to make any deduction from the amount payable to the holder
         of such depositary receipt from any amount received by the custodian in
         respect of the U.S. Government Obligation or the specific payment of
         principal of or interest on the U.S. Government Obligation evidenced by
         such depositary receipt.

               (2)   No Event of Default or event which with notice or lapse of
         time or both would become an Event of Default with respect to the
         Securities of such series shall have occurred and be continuing on the
         date of such deposit.

               (3)   In the case of an election under Section 1502, the Company
         shall have delivered to the Trustee an Opinion of Counsel to the effect
         that, and based thereon such opinion shall confirm that, the Holders of
         the Outstanding Securities of such series will not recognize income,
         gain or loss for Federal income tax purposes as a result of such
         defeasance and will be subject to Federal income tax on the same
         amounts, in the same manner and at the same times as would have been
         the case if such defeasance had not occurred. Such opinion shall be
         based upon at least one of the following authorities (issued, enacted
         or promulgated after the date of this Indenture), substantially on
         point and to the foregoing effect: (i) a public ruling of the Internal
         Revenue Service, (ii) a private ruling of the Internal Revenue Service
         issued to the Company with respect to the Securities, (iii) a provision
         of the Internal Revenue Code,




                                       85

<PAGE>   94
         (iv) a final regulation promulgated by the Department of the Treasury,
         or (v) a change in the applicable Federal income tax law.

               (4)   In the case of an election under Section 1503, the Company
         shall have delivered to the Trustee an Opinion of Counsel to the effect
         that the Holders of the Outstanding Securities of such series will not
         recognize income, gain or loss for Federal income tax purposes as a
         result of such covenant defeasance and will be subject to Federal
         income tax on the same amounts, in the same manner and at the same
         times as would have been the case if such covenant defeasance had not
         occurred.

Section 1505. DEPOSITED MONEY AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD IN
TRUST; OTHER MISCELLANEOUS PROVISIONS.

         Subject to the provisions of the last paragraph of Section 1003, all
money and U.S. Government Obligations (including the proceeds thereof) deposited
with the Trustee or other qualifying trustee (collectively, for purposes of this
Section 1505, the "Trustee") pursuant to Section 1504 in respect of the
Outstanding Securities of such series shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Securities and this
Indenture, to the payment, either directly or through any Paying Agent (but not
including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities, of all sums due and to become due
thereon in respect of principal (and premium, if any) and interest, but such
money need not be segregated from other funds except to the extent required by
law. Money so held in trust shall not be subject to the provisions of Article
Thirteen.

         Anything herein to the contrary notwithstanding, the Trustee shall
deliver or pay to the Company from time to time upon Company Request any money
or U.S. Government Obligations held by it as provided in Section 1504 which in
the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to
effect an equivalent defeasance or covenant defeasance.

Section 1506. COUNTERPARTS.

         This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

         I am a member of the State Bar of Massachusetts and express no opinion
with respect to the applicability of any law other than the laws of the
Commonwealth of Massachusetts and United States Federal laws. To the extent that
any applicable document is stated to be governed by the laws of another
jurisdiction, I have assumed for purposes of this opinion that the laws of such
jurisdiction are identical to the laws of the Commonwealth of Massachusetts.

         I have relied as to certain matters on information obtained from public
officials, officers of the Company, and other sources believed by me to be
responsible and I have assumed that the Indentures will be duly authorized,
executed, and delivered by the respective Trustees thereunder, the Deposit
Agreement will be duly authorized, executed, and delivered by the Depositary
thereunder, the Warrant Agreement will be duly authorized, executed and
delivered by the Warrant Agent thereunder and the Stock Purchase Contracts will
be duly authorized, executed and delivered by the other parties thereto,
assumptions which I have not independently verified.

         I hereby consent to the filing of this opinion with the Commission as
an exhibit to the Registration Statement in accordance with the requirements of
Item 601(b)(5) of Regulation S-K under the Securities Act and to the use of my
name therein and in the related Prospectus under the caption "Validity of
Securities." In

giving such consent, I do not hereby admit that I am in the category of persons
whose consent is required under Section 7 of the Securities Act or the rules and
regulations of the Commission.

(1)  Earnings in the fiscal year ended January 1, 1995 were inadequate to cover
     fixed charges by $17.4 million. Income (loss) from continuing operations
     before income taxes for this fiscal year includes a goodwill write-down of
     $40.3 million and restructuring charges of $30.4 million. Without this
     write-down and these charges, the ratio of earnings to fixed charges would
     have been 5.50x.

(2)  Income (loss) from continuing operations before income taxes for fiscal
     1997 includes an asset impairment charge of $28.2 million. Without this
     charge, the ratio of earnings to fixed charges would have been 5.65x.
