ABOUT THIS PROSPECTUS
 
  This prospectus is part of a registration statement that we filed with the
SEC utilizing a "shelf" registration process. Under this shelf process, we
may, over the next two years, sell any combination of the securities described
in this prospectus in one or more offerings up to a total dollar amount of
$950,000,000. This prospectus provides you with a general description of the
securities we may offer. Each time we sell securities, we will provide a
prospectus supplement that will contain specific information about the terms
of that offering. The prospectus supplement may also add, update or change
information contained in this prospectus. You should read both this prospectus
and any prospectus supplement together with additional information described
under the heading WHERE YOU CAN FIND MORE INFORMATION.
 
  We are participating in the SEC's plain English program. This is an
initiative launched by the SEC to make prospectuses and other information more
understandable to the general investor. We believe we have included all
information material to investors but certain details that may be important
for specific investment purposes have not been included. To see more detail,
you should read the exhibits filed with this registration statement.
 
WHERE YOU CAN FIND MORE INFORMATION
 
  We file annual, quarterly and special reports, proxy statements and other

Internet at the SEC's web site at http://www.sec.gov. You may also read and
copy any document we file at the SEC's public reference rooms in Washington,
D.C., New York, New York and Chicago, Illinois. Please call the SEC at 1-800-
SEC-0330 for further information on the public reference rooms.
 
  The SEC allows us to "incorporate by reference" the information we file with
them, which means that we can disclose important information to you by
referring you to those documents. The information incorporated by reference is
an important part of this prospectus, and information that we file later with
the SEC will automatically update and supersede this information. We
incorporate by reference the documents listed below and any future filings
made with the SEC under Sections 13(a), 13(c), 14, or 15(d) of the Securities
Exchange Act of 1934 until we sell all of the securities.

THE COMPANY
 
  Dominion Resources, Inc. is a holding company headquartered in Richmond,
Virginia. Our operating subsidiaries are:
 
 . Virginia Power/North Carolina Power, principally an electric utility serving
  two million residences and businesses in a 30,000-square-mile region from
  northern Virginia to northeastern North Carolina. It owns and operates
  nuclear, coal, natural gas, oil and hydroelectric power stations;
 
 . Dominion Energy, Inc., an independent power and natural gas subsidiary. It has
  ownership and operating interests in 27 generating facilities in six U.S.
  states, Argentina, Belize, Bolivia and Peru. This company has about 460
  billion cubic feet of proven natural gas reserves throughout several major
  regions of the United States;
 
 . Dominion Capital, Inc., a financial services and real estate subsidiary, with
  commercial and mortgage lending entities, a full-service commercial real
  estate company, a large hydroelectric station in Louisiana, and a variety of
  debt and equity investments; and
 
 . East Midlands Electricity plc, principally an electric power distribution and
  supply company serving 2.3 million homes and businesses in the East Midlands
  region of the United Kingdom.
 
USE OF PROCEEDS
 
  The net proceeds from the sale of the offered securities will be used for
general corporate purposes including repayment of debt. This debt may include
approximately $910 million incurred in connection with the purchase of East
Midlands in early 1997.
 
RATIO OF EARNINGS TO FIXED CHARGES
 
  The ratio of earnings to fixed charges for each of the periods indicated is
as follows:

</TABLE>
 
  These computations include us and our subsidiaries, and 50% or less equity
companies. For these ratios, "earnings" is determined by adding "total fixed
charges" (excluding interest capitalized), income taxes, minority common
stockholders equity in net income and amortization of interest capitalized to
income from continuing operations after eliminating equity in undistributed
earnings and adding back losses of companies in which at least 20% but less
than 50% equity is owned. For this purpose, "total fixed charges" consists of
(1) interest on all indebtedness and amortization of debt discount and expense,
(2) interest capitalized and (3) an interest factor attributable to rentals.

DESCRIPTION OF DEBT SECURITIES
 
  The Debt Securities will be our direct unsecured general obligations. The
Debt Securities will be either senior debt securities or subordinated debt
securities. The Debt Securities will be issued under one or more separate
indentures between us and The Chase Manhattan Bank as Trustee. Senior Debt
Securities will be issued under a "Senior Indenture" and Subordinated Debt
Securities will be issued under a "Subordinated Indenture". Together the Senior
Indentures and the Subordinated Indentures are called "Indentures".
 
  We have summarized selected provisions of the Indentures below. The summary
is not complete. The forms of the Indentures have been filed as exhibits to the
registration statement and you should read the Indentures for provisions that
may be important to you. In the summary below, we have included references to
section numbers of the applicable Indentures so that you can easily locate
these provisions. Capitalized terms used in the summary have the meanings
specified in the Indentures.
 
GENERAL
 
  The Debt Securities will be our direct, unsecured obligations. The Senior
Debt
Securities will rank equally with all of our other senior and unsubordinated
debt. The Subordinated Debt Securities will have a junior position to all of
our Senior Debt.
 
  Because we are a holding company that conducts all of our operations through
our subsidiaries, holders of Debt Securities will generally have a junior
position to claims of creditors of our subsidiaries, including trade creditors,
debtholders, secured creditors, taxing authorities, guarantee holders and any
preferred stockholders. Virginia Power has 6,890,140 outstanding shares of
preferred stock. All of our operating subsidiaries have ongoing corporate debt
programs used to finance their business activities. As of June 30, 1997, our
subsidiaries had approximately $7.8 billion of outstanding debt.
 
  A prospectus supplement and a supplemental indenture relating to any series
of Debt Securities being offered will include specific terms relating to the
offering. These terms will include some or all of the following:
 
 . The title and type of the Debt Securities;
 
 . The total principal amount of the Debt Securities;
 
 . The percentage of the principal amount at which the Debt Securities will be
  issued and any payments due if the maturity of the Debt Securities is
  accelerated;
 
 . The dates on which the principal of the Debt Securities will be payable;
 
 . The interest rate which the Debt Securities will bear and the interest
  payment dates for the Debt Securities;
 
 . Any optional redemption periods;
 
 . Any sinking fund or other provisions that would obligate us to repurchase or
  otherwise redeem the Debt Securities;
 
 . Any provisions granting special rights to holders when a specified event
  occurs;
 
 . Any changes to or additional Events of Defaults or covenants;
 
 . Any special tax implications of the Debt Securities, including provisions for
  Original Issue Discount Securities, if offered; and
 
 . Any other terms of the Debt Securities.
                                       4
<PAGE>
 
    None of the Indentures limits the amount of Debt Securities that may be
issued. Each Indenture allows Debt Securities to be issued up to the principal
amount that may be authorized by us and may be in any currency or currency unit
designated by us.
 
    Debt Securities of a series may be issued in registered, bearer, coupon or
global form. (Sections 201 & 203.)
 
DENOMINATIONS
 
    The prospectus supplement for each issuance of Debt Securities will state
whether the securities will be issued in registered form of $1,000 each or
multiples thereof or bearer form of $5,000 each.
 
SUBORDINATION
 
    Under the Subordinated Indenture, payment of the principal, interest and any
premium on the Subordinated Debt Securities will generally be subordinated and
junior in right of payment to the prior payment in full of all Senior Debt. The
Subordinated Indenture provides that no payment of principal, interest and any
premium on the Subordinated Debt Securities may be made in the event:
 
 .  of any insolvency, bankruptcy or similar proceeding involving the Company or
   our property, or
 
 .  we fail to pay the principal, interest, any premium or any other amounts on
   any Senior Debt when due.
 
    The Subordinated Indenture will not limit the amount of Senior Debt that we
may incur.
 
    "Senior Debt" is defined to include all notes or other unsecured evidences
of indebtedness including guarantees of the Company for money borrowed by the
Company, not expressed to be subordinate or junior in right of payment to any
other indebtedness of the Company.


CONSOLIDATION, MERGER OR SALE
 
    Each Indenture generally permits a consolidation or merger between us and
another corporation. They also permit the sale by us of all or substantially
all of our property and assets. If this happens, the remaining or acquiring
corporation shall assume all of our responsibilities and liabilities under the
Indentures including the payment of all amounts due on the Debt Securities and
performance of the covenants in the Indentures.
 
    However, we will only consolidate or merge with or into any other
corporation or sell all or substantially all of our assets according to the
terms and conditions of the Indentures. The remaining or acquiring corporation
will be substituted for us in the Indentures with the same effect as if it had
been an original party to the Indenture. Thereafter, the successor corporation
may exercise our rights and powers under any Indenture, in our name or in its
own name. Any act or proceeding required or permitted to be done by our Board of
Directors or any of our officers may be done by the board or officers of the
successor corporation. If we sell all or substantially all of our assets, we
shall be released from all our liabilities and obligations under any Indenture
and under the Debt Securities. (Sections 801 & 802.)


MODIFICATION OF INDENTURES
 
    Under each Indenture our rights and obligations and the rights of the
holders may be modified with the consent of the holders of a majority in
aggregate principal amount of the outstanding Debt Securities
                                       5
<PAGE>
 
of each series affected by the modification. No modification of the principal
or interest payment terms, and no modification reducing the percentage required
for modifications, is effective against any holder without its consent.
(Sections 901 & 902.)
 
EVENTS OF DEFAULT
 
    "Event of Default" when used in an Indenture, will mean any of the
 following:

 . failure to pay the principal or any premium on any Debt Security when due;
 
 . failure to deposit any sinking fund payment when due;
 
 . failure to pay interest on any Debt Security for 30 days;
 
 . failure to perform any other covenant in the Indenture that continues for 90
  days after being given written notice;
 
 . certain events in bankruptcy, insolvency or reorganization of the Company; or
 
 . any other Event of Default included in any Indenture or supplemental
  indenture. (Section 501.)
 
    An Event of Default for a particular series of Debt Securities does not
necessarily constitute an Event of Default for any other series of Debt
Securities issued under an Indenture. The Trustee may withhold notice to the
holders of Debt Securities of any default (except in the payment of principal
or interest) if it considers such withholding of notice to be in the best
interests of the holders. (Section 602.)
 
    If an Event of Default for any series of Debt Securities occurs and
continues, the Trustee or the holders of at least 25% in aggregate principal
amount of the Debt Securities of the series may declare the entire principal of
all the Debt Securities of that series to be due and payable immediately. If
this happens, subject to certain conditions, the holders of a majority of the
aggregate principal amount of the Debt Securities of that series can void the
declaration. (Section 502.)
 
    Other than its duties in case of a default, a Trustee is not obligated to
exercise any of its rights or powers under any Indenture at the request, order
or direction of any holders, unless the holders offer the Trustee reasonable
indemnity. (Section 601.) If they provide this reasonable indemnification, the
holders of a majority in principal amount of any series of Debt Securities may
direct the time, method and place of conducting any proceeding or any remedy
available to the Trustee, or exercising any power conferred upon the Trustee,
for any series of Debt Securities. (Section 512.)

 
COVENANTS
 
    Under the Indentures, we will:
 
 .  pay the principal, interest and any premium on the Debt Securities when due;
 
 .  maintain a place of payment;
 
 .  deliver a report to the Trustee at the end of each fiscal year reviewing the
   Company's obligations under the Indentures; and
 
 .  deposit sufficient funds with any paying agent on or before the due date for
   any principal, interest or any premium.

 
PAYMENT AND TRANSFER
 
    Principal, interest and any premium on fully registered securities will be
paid at designated places. Payment will be made by check mailed to the persons
in whose
 
                                       6
<PAGE>
 
names the Debt Securities are registered on days specified in the Indentures or
any prospectus supplement. Debt Securities payments in other forms will be paid
at a place designated by us and specified in a prospectus supplement.
(Section 307.)
 
  Fully registered securities may be transferred or exchanged at the corporate
trust office of the Trustee or at any other office or agency maintained by us
for such purposes, without the payment of any service charge except for any tax
or governmental charge. (Section 1002.)
 
GLOBAL SECURITIES
 
  The Debt Securities of a series may be issued in whole or in part in the form
of one or more global certificates that will be deposited with a depositary
identified in a prospectus supplement. Unless it is exchanged in whole or in
part for Debt Securities in definitive form, a global certificate may generally
be transferred only as a whole unless it is being transferred to certain
nominees of the depositary. (Section 203.)
 
  Unless otherwise stated in any prospectus supplement, The Depository Trust
Company, New York, New York ("DTC") will act as depositary. Beneficial
interests in global certificates will be shown on, and transfers of global
certificates will be effected only through, records maintained by DTC and its
participants.
 
DEFEASANCE
 
  We will be discharged from our obligations on the Debt Securities of any
series at any time if we deposit with the Trustee sufficient cash or government
securities to pay the principal, interest, any premium and any other sums due
to the stated maturity date or a redemption date of the Debt Securities of the
series. If this happens, the holders of the Debt Securities of the series will
not be entitled to the benefits of the Indenture except for registration of
transfer and exchange of Debt Securities and replacement of lost, stolen or
mutilated Debt Securities. (Section 401.)
 
  Under Federal income tax law as of the date of this prospectus, a discharge
may be treated as an exchange of the related Debt Securities. Each holder might
be required to recognize gain or loss equal to the difference between the
holder's cost or other tax basis for the Debt Securities and the value of the
holder's interest in the trust. Holders might be required to include as income
a different amount than would be includable without the discharge. Prospective
investors are urged to consult their own tax advisers as to the consequences of
a discharge, including the applicability and effect of tax laws other than the
Federal income tax law.

Dividends
 
  Common shareholders may receive dividends when declared by the Board of
Directors. Dividends may be paid in cash, stock or other form. In certain
cases, common shareholders may not receive dividends until we have satisfied

additional common stock we issue will also be fully paid and non-assessable.

PREFERRED STOCK
 
  The following description of the terms of the preferred stock sets forth
certain general terms and provisions of our authorized preferred stock. If we
offer preferred stock, the specific designations and rights will be described
in the prospectus supplement and a description will be filed with the SEC.
 
  Our Board of Directors can, without approval of shareholders, issue one or
more series of preferred stock. The Board can also determine the number of
shares of each series and the rights, preferences and limitations of each
series including the dividend rights, voting rights, conversion rights,
redemption rights and any liquidation preferences of any wholly unissued series
of preferred stock, the number of shares constituting each series and the terms
and conditions of issue. In some cases, the issuance of preferred stock could
delay a change in control of the Company and make it harder to remove present
management. Under certain circumstances, preferred stock could also restrict
dividend payments to holders of our common stock.
 
  The preferred stock will, when issued, be fully paid and non-assessable.
 
  The transfer agent, registrar, and dividend disbursement agent for a series

which holders of the preferred stock have the right to elect directors or to
vote on any other matter.
 
VIRGINIA STOCK CORPORATION ACT AND THE ARTICLES AND THE BYLAWS
 
GENERAL
 
   We are a Virginia corporation subject to the Virginia Stock Corporation Act
(the
                                       8
<PAGE>
 
"Virginia Act"). Provisions of the Virginia Act, in addition to provisions of
our Articles of Incorporation and Bylaws, address corporate governance issues,
including the rights of shareholders. Some of these provisions could hinder
management changes while others could have an anti-takeover effect. This anti-
takeover effect may, in some circumstances, reduce the control premium that
might otherwise be reflected in the value of our common stock. If you are
buying this stock as part of a short-term investment strategy, this might be
especially important to you.
 
  We have summarized the key provisions below. The descriptions are not
complete.You should read the actual provisions of our Articles and Bylaws and
the Virginia Act that relate to your individual investment strategy.
 
BUSINESS COMBINATIONS
 
  The Virginia Act and our Articles generally require that any merger, share
exchange or sale of substantially all of the assets of a corporation be
approved by at least two-thirds of the votes entitled to be cast by each voting
group entitled to vote.
 
  Section 13.1-725 of the Virginia Act contains several provisions relating to
transactions with "interested shareholders." Interested Shareholders are
holders of more than 10% of any class of a corporation's outstanding voting
shares. Transactions between a corporation and an Interested Shareholder are
referred to as Affiliated Transactions. The Virginia Act requires that material
affiliated transactions must be approved by at least two-thirds of the
shareholders not including the Interested Shareholder. Affiliated Transactions
requiring this two-thirds approval include mergers, share exchanges, material
dispositions of corporate assets, dissolution or any reclassification of the
corporation with its subsidiaries which increases the percentage of voting
shares owned by an Interested Shareholder by more than five percent.
 
  For three years following the time that a shareholder becomes an Interested
Shareholder, a Virginia corporation cannot engage in an Affiliated Transaction
with the Interested Shareholder without approval of two-thirds of the
disinterested voting shares, and majority approval of "Disinterested
Directors." A Disinterested Director is a director who was a director on the
date on which an Interested Shareholder became an Interested Shareholder and
was recommended for election or elected by a majority of the Disinterested
Directors then on the board. After three years, the approval of the
Disinterested Directors is no longer required.
 
  The provisions of the Virginia Act relating to Affiliated Transactions do not
apply if a majority of Disinterested Directors approve the acquisition of
shares making a person an Interested Shareholder.
 
  The Virginia Act permits corporations to opt out of the Affiliated
Transactions provisions. We have not opted out.
 
  The Virginia Act also contains provisions regulating certain "control share
acquisitions," which are transactions causing the voting strength of any person
acquiring beneficial ownership of shares of a public corporation in Virginia to
meet or exceed certain threshold voting percentages (20%, 33 1/3% or 50%).
Shares acquired in a control share acquisition have no voting
                                       9
<PAGE>
 
rights unless the voting rights are granted by a majority vote of all
outstanding shares other than those held by the acquiring person or any officer
or employee-director of the corporation. The acquiring person may require that
a special meeting of the shareholders be held to consider the grant of voting
rights to the shares acquired in the control share acquisition.
 
  Our Bylaws give us the right to redeem the shares purchased by an acquiring
person in a control share acquisition. We can do this if the acquiring person
fails to deliver a statement to us listing information required by the Virginia
Act or if our shareholders vote not to grant voting rights to the acquiring
person.
 
  The Virginia Act permits corporations to opt out of the control share
acquisition provisions. We have not opted out.
 
DIRECTORS' DUTIES
 
  The standards of conduct for directors of Virginia corporations are listed in
Section 13.1-690 of the Virginia Act. Directors must discharge their duties in
accordance with their "good faith business judgement of the best interest of
the corporation". Directors may rely on the advice or acts of others, including
officers, employees, attorneys, accountants and board committees if they have a
good faith belief in their competence. Directors' actions are not subject to a
"reasonableness" or "prudent person" standard. Virginia's Federal courts have
focused on the process involved with directors' decision-making and are
generally supportive of directors if they have based their decision on an
informed process. These elements of Virginia law
could make it more difficult to take over a Virginia corporation than
corporations in other states.
 
BOARD OF DIRECTORS
 
  Members of our Board of Directors serve staggered three year terms. This
means that only one-third of our directors are elected each year.
 
SHAREHOLDER PROPOSALS AND DIRECTOR NOMINATIONS
 
  Our shareholders can submit shareholder proposals and nominate candidates for
the Board of Directors if the shareholders follow advance notice procedures
described in our Bylaws.
 
  To nominate directors, shareholders must submit a written notice to our
corporate secretary at least 60 days before a scheduled meeting. The notice
must include the name and address of the shareholder and of the nominee, a
description of any arrangements between the shareholder and the nominee,
information about the nominee required by the SEC, the written consent of the
nominee to serve as a director and other information.
 
  Shareholder proposals must be submitted to our corporate secretary at least
90 days before the first anniversary of the date of our last annual meeting.
The notice must include a description of the proposal, the reasons for
presenting the proposal at the annual meeting, the text of any resolutions to
be presented, the shareholder's name and address and number of shares held and
any material interest of the shareholder in the proposal.
 
  Director nominations and shareholder proposals that are late or that do not
include
 
                                       10
<PAGE>
 
all required information may be rejected. This could prevent shareholders from
bringing certain matters before an annual or special meeting, including making
nominations for directors.
 
MEETINGS OF SHAREHOLDERS
 
  Under our Bylaws, meetings of the shareholders may be called only by the
chairman of the board, the president or a majority of the Board of Directors.
This provision could have the effect of delaying until the next annual
shareholders' meeting shareholder actions which are favored by the holders of a
majority of our outstanding voting securities, because such person or entity,
even if it acquired a majority of the outstanding voting securities of Dominion
Resources, would be able to take action as a shareholder, such as electing new
directors or approving a merger, only at a duly called shareholders' meeting.
 
AMENDMENT OF ARTICLES AND BYLAWS
 
  Generally, our Articles may be amended by a majority of the outstanding votes
entitled to be cast by each voting group entitled to vote on a given matter.
Some provisions of the Articles, however, may only be amended or repealed by
two-thirds of the votes entitled to be cast by each voting group entitled to
vote.
 
INDEMNIFICATION
 
  We indemnify our officers and directors to the fullest extent permitted under
Virginia law against all liabilities incurred in connection with their service
to us.
 
LIMITATION OF LIABILITY
 
  Our Articles provide that our directors will not be personally liable for
monetary damages to us for breaches of their fiduciary duty as directors,
unless they violated their duty of loyalty to us or our stockholders, acted in
bad faith, knowingly or intentionally violated the law, authorized illegal
dividends or redemptions or derived an improper personal benefit from their
action as directors. This provision applies only to claims against directors
arising out of their role as directors and not in any other capacity (such as
an officer or employee). Directors remain liable for violations of the federal
securities laws and we retain the right to pursue legal remedies other than
monetary damages, such as an injunction or rescission for breach of the
director's duty of care.
 
PLAN OF DISTRIBUTION
 
  We may sell the offered securities (a) through agents; (b) through
underwriters or dealers; or (c) directly to one or more purchasers.
 
BY AGENTS
 
  Offered securities may be sold through agents designated by us. The agents
agree to use their reasonable best efforts to solicit purchases for the period
of their appointment.
 
BY UNDERWRITERS
 
  If underwriters are used in the sale, the offered securities will be acquired
by the underwriters 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. The underwriters will be obligated to purchase
all the securities of
 
                                       11
<PAGE>
 
the series offered if any of the securities are purchased. Any initial public
offering price and any discounts or concessions allowed or re-allowed or paid
to dealers may be changed from time to time.
 
DIRECT SALES
 
  Offered securities may also be sold directly by us. In this case, no
underwriters or agents would be involved.
 
GENERAL INFORMATION
 
  Underwriters, dealers and agents that participate in the distribution of the
offered securities may be underwriters as defined in the Securities Act of 1933
(the "Act"), and any discounts or commissions received by them from us and any
profit on the resale of the offered securities by them may be treated as
underwriting discounts and commissions under the Act. Any underwriters or
agents will be identified and their compensation described in a prospectus
supplement.
 
  We may have agreements with the underwriters, dealers and agents to indemnify
them against certain civil liabilities, including liabilities under the Act, or
to contribute with respect to payments which the underwriters, dealers or
agents may be required to make.
 
  Underwriters, dealers and agents may engage in transactions with, or perform
services for, us or our subsidiaries in the ordinary course of their
businesses.
 
LEGAL OPINIONS
 
  Thomas F. Farrell, II, Esq., who is our Senior Vice President--Corporate and
General Counsel, or another of our lawyers, will issue an opinion about the
legality of the offered securities for us. Any underwriters will be advised
about other issues relating to any offering by their own legal counsel.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Article VI of Dominion Resources' Articles of Incorporation mandates
indemnification of its directors and officers to the full extent permitted by
the Virginia Stock Corporation Act (the Virginia Act) and any other applicable
law. The Virginia Act permits a corporation to indemnify its directors and
officers against liability incurred in all proceedings, including derivative
proceedings, arising out of their service to the corporation or to other
corporations or enterprises that the officer or director was serving at the
request of the corporation, except in the case of willful misconduct or a
knowing violation of a criminal law. Dominion Resources is required to
indemnify its directors and officers in all such proceedings if they have not
violated this standard.
 
  In addition, Article VI of Dominion Resources' Articles of Incorporation
limits the liability of its directors and officers to the full extent permitted
by the Virginia Act as now and hereafter in effect. The Virginia Act places a
limit on the liability of a director or officer in derivative or shareholder
proceedings equal to the lesser of (i) the amount specified in the
corporation's articles of incorporation or a shareholder-approved bylaw; or
(ii) the greater of (a) $100,000 or (b) twelve months of cash compensation
received by the director or officer. The limit does not apply in the event the
director or officer has engaged in willful misconduct or a knowing violation of
a criminal law or a federal or state securities law. The effect of Dominion
Resources' Articles of Incorporation, together with the Virginia Act, is to
eliminate liability of directors and officers for monetary damages in
derivative or shareholder proceedings so long as the required standard of
conduct is met.
 
  Dominion Resources has purchased directors' and officers' liability insurance
policies. Within the limits of their coverage, the policies insure (1) the
directors and officers of Dominion Resources against certain losses resulting
from claims against them in their capacities as directors and officers to the
extent that such losses are not indemnified by Dominion Resources and (2)
Dominion Resources to the extent that it indemnifies such directors and
officers for losses as permitted under the laws of Virginia.

ITEM 17. UNDERTAKINGS.
 
    The undersigned registrant hereby undertakes:
 
        (1) To file, during any period in which offers or sales are being made,
  a post-effective amendment to this registration statement:
  
            (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act of 1933;
 
            (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement. Notwithstanding the foregoing, any
        increase or decrease in 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 SEC pursuant to Rule 424(b), if, in the aggregate, the changes
        in volume and price represent no more than 20 percent change in the
        maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement.
 
            (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement; provided, however, that paragraphs (a)(1)(i) and (a)(1)(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 with or furnished to the SEC by the registrant pursuant to Section
        13 or Section 15(d) of the Securities Exchange Act of 1934 that are
        incorporated by reference in this registration statement.
        
        (2) That, for the purpose of determining any liability under the
  Securities Act of 1933, each such post-effective amendment shall be deemed
  to be a new registration statement relating to the securities offered
  therein, and the offering of such securities at that time shall be deemed
  to be the initial bona fide offering thereof.
 
                                      II-2
<PAGE>
 
    (3) To remove from registration by means of a post-effective amendment
  any of the securities being registered which remain unsold at the
  termination of the offering.
 
    (4) The undersigned registrant hereby undertakes that, for purposes of
  determining any liability under the Securities Act of 1933, each filing of
  the registrant's annual report pursuant to Section 13(a) or 15(d) of the
  Securities Exchange Act of 1934 (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) 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.
 
    (5) Insofar as indemnification for liabilities arising under the
  Securities Act of 1933 may be permitted to directors, officers and
  controlling persons of the registrant pursuant to the foregoing provisions,
  or otherwise, the registrant has been advised that in the opinion of the
  Securities and Exchange Commission such indemnification is against public
  policy as expressed in the Act and is, therefore, unenforceable. In the
  event that a claim for indemnification against such liabilities (other than
  the payment by the registrant of expenses incurred or paid by a director,
  officer or controlling person of the registrant in the successful defense
  of any action, suit or proceeding) is asserted by such director, officer or
  controlling person in connection with the securities being registered, the
  registrant will, unless in the opinion of its counsel the matter has been
  settled by controlling precedent, submit to a court of appropriate
  jurisdiction the question whether such indemnification by it is against
  public policy as expressed in the Act and will be governed by the final
  adjudication of such issue.
 
    (6) The undersigned registrant hereby further undertakes:
 
      (i) For purposes of determining any liability under the Securities
    Act of 1933, 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 shall be
    deemed to be part of this registration statement as of the time it was
    declared effective.
 
      (ii) For the purpose of determining any liability under the
    Securities Act of 1933, 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.

               [FORM OF DEBT SECURITIES UNDERWRITING AGREEMENT]

                                    , 199__


[Representative Name]
[Address]

Ladies and Gentlemen;

     Dominion Resources, Inc., a Virginia corporation (the "Company"), proposes
to issue and sell to the several Underwriters named in Schedule I hereto (the
"Underwriters") for whom you are acting as representative (in such capacity you
shall be referred to as the "Representative"), $_______ principal amount of its
___% Debt Securities Due _____ (the "Debt Securities"). The Debt Securities are
to be issued under an indenture (the "Indenture") dated as of __________, 199
between the Company and The Chase Manhattan Bank, as trustee.

     The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3, including a prospectus,
relating to the registration of the Debt Securities and certain other securities
of the Company under the Securities Act of 1933, as amended (the "Securities
Act"), and the offering thereof from time to time in accordance with Rule 415 of
the rules and regulations promulgated under the Securities Act (the "Rules and
Regulations"). Such registration statement has been declared effective by the
Commission. The registration statement at the time it became effective,
including the information (if any) deemed to be part of the registration
statement at the time of effectiveness pursuant to Rule 430A or Rule 434 under
the Securities Act of 1933, as amended (the "Securities Act"), is hereinafter
referred to as the Registration Statement; and the prospectus (including any
prospectus supplement whether or not such prospectus supplement is required to
be filed by the Company pursuant to Rule 424(b) of the Rules and Regulations) in
the form first used to confirm sales of Debt Securities is hereinafter referred
to as the Prospectus (including, in the case of all references to the
Registration Statement and the Prospectus, documents incorporated therein by
reference).

                                   Section I

     1.1  The Company represents and warrants to you and to each of the other
Underwriters as of the date hereof that:

     (a)  The Registration Statement, on the effective date thereof, conformed
in all material respects to the requirements of the Securities Act, the Trust
Indenture Act of 1939, as amended (the "Trust Indenture Act"), and the Rules and
Regulations and did not include any untrue statement of a material fact or omit
to state any material fact necessary
<PAGE>
 
to make the statements therein, in the light of the circumstances under which
they were made, not misleading, and on the date of this Agreement the
Registration Statement and the Prospectus conform in all material respects to
the requirements of the Securities Act, the Trust Indenture Act and the Rules
and Regulations and neither of such documents includes any untrue statement of a
material fact or omits to state any material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading; provided, however, that the Company makes no
                      --------  -------                           
representation or warranty as to the information contained in or omitted from
such documents, in reliance upon and in conformity with information furnished to
the Company by or on behalf of the Underwriters through the Representative
specifically for inclusion therein or the part of the Registration Statement
which constitutes the Trustee's Statement of Eligibility under the Trust
Indenture Act (the "Form T-1").

     (b) The documents incorporated, or deemed to be incorporated, by reference
in the Prospectus pursuant to Item 12 of the requirements of Form S-3 under the
Securities Act, at the time they were or thereafter are filed with the
Commission complied, and will comply, in all material respects with the
applicable requirements of the Exchange Act of 1934, as amended (the "Exchange
Act") and the rules and regulations of the Commission promulgated thereunder.

     1.2  Each of the several Underwriters represents and warrants to, and
agrees with, the Company, its directors and such of its officers as shall have
signed the Registration Statement, and to each other Underwriter, that the
information furnished to the Company by, or through the Representative on behalf
of, such Underwriter expressly for use in the Registration Statement or the
Prospectus does not contain an untrue statement of a material fact and does not
omit to state a material fact in connection with such information required to be
stated therein or necessary to make such information not misleading.

                                  Section II

     Subject to the terms and conditions and in reliance upon the
representations and warranties herein set forth, the Company agrees to sell to
each Underwriter, and each Underwriter agrees, severally and not jointly, to
purchase from the Company, at a purchase price equal to the percentage of
principal amount as set forth on Schedule I hereto, the principal amount of Debt
Securities, [plus, accrued interest, if any, from _______, 199__,] set forth
opposite such Underwriter's name in Schedule I hereto. It is understood that the
Underwriters propose to offer the Debt Securities for sale as set forth in the
Prospectus.

                                  Section III

     Payment for the Debt Securities shall be made by or on behalf of the
several Underwriters by the wire transfer of immediately available funds to the

with the provisions of Section VIII) following the date of this Agreement, or if

day following the date of this Agreement (unless postponed in accordance with
the provisions of Section VIII), or at such other time on the same or such other
earlier date as shall be agreed upon by the Representative and the Company. The
time and date of such payment are hereinafter referred to as the Closing Date.
Delivery of the Securities shall be made to the Representative for the
respective accounts of the Underwriters against payment by the Underwriters
through the Representative of the purchase price thereof to or upon the order of
the Company by wire transfer of Federal funds or other immediately available
funds or in such other manner of payment as may be agreed by the Company and the
Representative.

     Delivery of any Debt Securities to be issued in definitive certificated
form shall be made on the Closing Date at such location, and in such names and
denominations, as the Representative shall designate at least two business days
in advance of the Closing Date. The Company agrees to have the Debt Securities
available for inspection, checking and packaging by the Representative in New
York, New York, not later than 1:00 PM on the business day prior to the Closing
Date. The closing for the purchase and sale of the Debt Securities shall occur
at the office of [Underwriters' Counsel] [Address] ("Counsel for the
Underwriters") or such other place as the parties hereto shall agree.

                                  Section IV

     The several obligations of the Underwriters hereunder are subject to the
following conditions:

     4.1 If the Company does not elect to rely on Rule 434 under the Rules and
Regulations, and if the filing of the Prospectus is required pursuant to Rule
424(b), the Prospectus (including a prospectus supplement) shall have been filed
with the Commission in the manner and within the time period required by Rule
424(b); and prior to the Closing Date, no stop order suspending the
effectiveness of the Registration Statement shall have been issued and no
proceedings for that purpose shall have been instituted, or, to the knowledge of
the Company, shall be contemplated by the Commission and the Representative
shall have received at such closing a certificate of the Company, dated the
Closing Date, to such effect.  If the Company elects to rely on Rule 434 under
the Rules and Regulations, immediately following the execution of this
Agreement, the Company will prepare an abbreviated term sheet that complies with
the requirements of Rule 434 under the Rules and Regulations and will provide
the Underwriter with copies of the form of Rule 434 Prospectus, in such number
as the Representative shall reasonably request, and if necessary, promptly file
or transmit for filing with the Commission the form of Prospectus complying with
Rule 434(c)(2) of the Rules and Regulations in accordance with Rule 424(b)
thereunder.

          4.2  Subsequent to the execution and delivery of this Agreement and
prior to the Closing Date, there shall not have occurred any material adverse
change in the condition, financial or otherwise, or in the earnings, business or
operations, of the Company and its subsidiaries, taken as a whole, from that set
forth in the Registration Statement.

          4.3  The Representative shall have received a certificate, dated the

true and correct (except for immaterial details) as of the Closing Date and (ii)
subsequent to the date of the latest financial statements in the Prospectus,

          4.4  You shall have received on the Closing Date an opinion of Thomas
F. Farrell, II, Esq., Senior Vice President - Corporate Affairs, or such other
counsel for the Company, as may be acceptable to the Representative, dated the
Closing Date, to the effect that:

          (a)    The Company has been duly incorporated and is an existing
corporation in good standing under the laws of the Commonwealth of Virginia,
with corporate power and authority to own, lease and operate its properties and
conduct its business as described in the Prospectus; and the Company is duly
qualified to do business as a foreign corporation in good standing in all other
jurisdictions in which it owns or leases substantial properties or in which the
conduct of its business requires such qualification except where the failure to
so qualify or be in good standing would not have a material adverse effect on
the Company and its subsidiaries, considered as one enterprise;

          (b)    Each significant subsidiary as defined in Rule 405 of
     Regulation C of the Securities Act (each a "Significant Subsidiary") of the
     Company has been duly incorporated and is validly existing as a corporation
     in good standing under the laws of the jurisdiction of its incorporation,
     has corporate power and authority to own, lease and operate its properties
     and conduct its business as described in the Prospectus; and, to the best
     of such counsel's knowledge, is duly qualified as a foreign corporation to
     transact business and is in good standing in each jurisdiction in which
     such qualification is required, except where the failure to so qualify or
     be in good standing would not have a material adverse effect on the Company
     and its subsidiaries, considered as one enterprise; all of the issued and
     outstanding capital stock of each Significant Subsidiary has been duly
     authorized and validly issued, is fully paid and nonassessable, and, except
     for directors' qualifying shares, if any, is owned by the Company free and
     clear of any mortgage, pledge, lien, encumbrance, claim or equity;


                                    Page 4
<PAGE>
 
          (c)    No consent, approval, authorization or order of, or filing
     with, any governmental agency or body or any court is required for the
     consummation of the transactions contemplated herein, except such as may be
     required under the Securities Act or state securities laws; and

          (d)    The execution, delivery and performance of this the Indenture
     and Agreement and the issuance and sale of the Debt Securities and
     compliance with the terms and provisions thereof will not result in a
     material breach or violation of any of the terms and provisions of, or
     constitute a default under, any statute, rule, regulation or order of any
     governmental agency or body or any court having jurisdiction over the
     Company or any Significant Subsidiary or any of their properties or, to the
     best of such counsel's knowledge, any agreement or instrument to which the
     Company or any of its Significant Subsidiaries is a party or by which the
     Company or any Significant Subsidiary is bound or to which any of the
     properties of the Company or any Significant Subsidiary is subject, or the
     articles of incorporation or bylaws of the Company or any Significant
     Subsidiary, and the Company has full power and authority to authorize,
     issue and sell the Debt Securities as contemplated by this Agreement.

           In addition, such counsel shall state that he or she has participated
in conferences with officers and other representatives of the Company,
representatives of Deloitte & Touche LLP, independent auditors for the Company,
and the Representative, at which the contents of the Registration Statement, the
Prospectus and any amendment thereof or supplement thereto and related matters
were discussed and although such counsel has not undertaken to investigate or
verify independently, and does not assume any responsibility for the accuracy,
completeness or fairness of the statements contained in the Registration
Statement or the Prospectus or any amendment thereof or supplement thereto, no
facts have come to the attention of such counsel which would lead such counsel
to believe that the Registration Statement or the Prospectus (other than the
historical, proforma, projected or other financial statements, information and
data and statistical information and data included or incorporated by reference
therein, and the Form T-1, in each case as to which no opinion need be given) at
the time the Registration Statement became effective, or as of the date of this
Agreement, contained any untrue statement of a material fact or omitted to state
any material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading or that the Prospectus
(other than the historical, proforma, projected or other financial statements,
information and data and statistical information and data included or
incorporated by reference therein, in each case as to which no opinion need be
given) as of the Closing Date includes any untrue statement of a material fact
or omits to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading.

          4.5  The Representative shall have received on the Closing Date an
opinion of McGuire, Woods, Battle & Boothe, L.L.P. counsel for the Company dated
the Closing Date, to the effect that:

          (a)  The Indenture has been duly authorized, executed and delivered by
          the Company and has been duly qualified under the Trust Indenture Act;
          the Securities have been duly authorized, executed, issued and
          delivered by the Company; the Indenture and the Debt Securities, when
          authenticated in the manner provided in the Indenture, constitute
          valid and legally binding obligations of the Company enforceable
          against the Company 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 (in
          rendering such opinion, such counsel may assume that the Indenture has
          been duly authorized, executed and delivered, and the Debt Securities
          have been duly authenticated, by the Trustee);

          (b)   This Agreement has been duly authorized, executed and delivered
          by the Company;

          In addition, subject to such counsel's customary qualifications about
the scope of its obligations in connection with its participation in the
preparation of documents, such counsel shall state that they have participated
in conferences with officers and other representatives of the Company,
representatives of Deloitte & Touche LLP, independent auditors for the Company,
the Representative, and Counsel for the Underwriters at which the contents of
the Registration Statement, the Prospectus and any amendment thereof or
supplement thereto and related matters were discussed and although such counsel
have not undertaken to investigate or verify independently, and do not assume
any responsibility for the accuracy, completeness or fairness of the statements
contained in the Registration Statement or the Prospectus or any amendment
thereof or supplement thereto, and did not participate in the preparation of the
documents incorporated by reference in the Registration Statement or the
Prospectus, no facts have come to the attention of such counsel which would lead
such counsel to believe that either the Registration Statement or the Prospectus
(other than the historical, proforma, projected or other financial statements,
information and data and statistical information and data included or
incorporated by reference therein, and the Form T-1, in each case as to which no
opinion need be given) at the time such Registration Statement became effective,
or as of the date of this Agreement, contained any untrue statement of a
material fact or omitted to state any material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, or that the Prospectus at the applicable Closing Date
(other than the historical, proforma, projected or other financial statements,
information and data and statistical information and data included or
incorporated by reference therein, in each case as to which no opinion need be
given) includes any untrue statement of a material fact or omits to state a
material fact necessary

                                    Page 6
<PAGE>
 
     in order to make the statements therein, in the light of the circumstances
     under which they were made, not misleading.

          In rendering such opinion, McGuire, Woods, Battle & Boothe, L.L.P. may
     rely (A) as to matters governed by New York law upon the opinion of Counsel
     for the Underwriters, referred to below and (B) as to matters of fact, to
     the extent they deem proper, on certificates of responsible officers of the
     Company and public officials.

          The opinion of McGuire, Woods, Battle & Boothe, L.L.P. shall be
     rendered to the Representative at the request of the Company and shall so
     state therein.

          4.6 The Representative shall have received from Counsel for the
     Underwriters, such opinion or opinions, dated the Closing Date, with
     respect to the validity of the Debt Securities, the Registration Statement,
     the Prospectus, this Agreement and other related matters as the
     Representative may reasonably request, and the Company shall have furnished
     to such counsel such documents as they reasonably request for the purpose
     of enabling them to pass upon such matters. In rendering such opinion,
     Counsel for the Underwriters may rely as to matters governed by Virginia
     law upon the opinion of Thomas F. Farrell Esq. or such other counsel
     referred to in paragraph 4.4 above.

          4.7 On the Closing Date, the Representative shall have received from
     Deloitte & Touche LLP a letter dated such date, in form and substance
     satisfactory to the Representative.

                                   Section V

     The obligations of the Company to sell and deliver the Debt Securities on
the Closing Date are subject to the condition that at the Closing Date, no stop
order suspending the effectiveness of the Registration Statement shall be in
effect or proceeding therefor shall have been instituted or, to the knowledge of
the Company, shall be contemplated.

     If the foregoing condition shall not have been satisfied, then the Company
shall be entitled, by notice in writing or by telegram to the Representative, to
terminate this Agreement without any liability on the part of the Company or any
Underwriter, except as provided in paragraphs 6.1 and 6.5 hereof.

                                  Section VI

     In further consideration of the agreements of the Underwriters herein
contained, the Company covenants as follows:

          6.1 To assist in any required qualification of the Debt Securities by 
     the Representative or on its behalf for offer and sale under the securities
     or blue sky laws of such States as the Representative may designate, to
     continue such qualification in effect so long as required for the
     distribution of the Debt Securities and to reimburse the Representative for
     any expenses (including filing fees and fees and disbursements of counsel)
     paid by the Representative or on its behalf to qualify the Debt Securities
     for offer and sale, to continue such qualification, to determine the
     eligibility of the Debt Securities for investment and to print the
     memoranda relating thereto; provided that the Company shall not be required
     to qualify as a foreign corporation in any jurisdiction in which it is not
     so qualified;

          6.2 Promptly to deliver to the Representative conformed copies of the
     Registration Statement (including all documents incorporated by reference
     therein) as originally filed and of all amendments thereto heretofore or
     hereafter filed, including

                                    Page 7
<PAGE>
 
     conformed copies of all exhibits except those incorporated by reference,
     and such number of copies of the Registration Statement (but excluding the
     exhibits), each related preliminary prospectus, the Prospectus, and any
     amendments and supplements thereto, as the Representative may reasonably
     request;

          6.3 If, at any time when a prospectus relating to the Debt Securities 
     is required to be delivered under the Securities Act in connection with
     sales by an Underwriter or dealer, any event occurs as a result of which
     the Prospectus as then amended or supplemented would include an untrue
     statement of a material fact or omit to state any material fact necessary
     to make the statements therein, in the light of the circumstances under
     which they were made, not misleading, or if it is necessary at any time to
     amend the Prospectus to comply with the Securities Act in connection with
     sales by an Underwriter or dealer, to advise the Representative of such
     event or necessity, as the case may be, and, promptly upon request made by
     the Representative, to prepare and file with the Commission an amendment or
     supplement which will correct such statement or omission or an amendment
     which will effect such compliance; provided that the expense of preparing
     and filing and such amendment or supplement (i) which is necessary in
     connection with such a delivery of a prospectus more than nine months after
     the date of this Agreement or (ii) which relates solely to the activities
     of any Underwriter shall be borne by the Underwriter or Underwriters or the
     dealer or dealers requiring the same; and provided further that the
     Representative shall, upon inquiry by the Company, advise the Company
     whether or not any Underwriter or dealer which shall have been selected by
     the Representative retains any unsold Debt Securities and, for the purposes
     of this paragraph 6.3, the Company shall be entitled to assume that the
     distribution of the Debt Securities has been completed when it is advised
     by the Representative that no Underwriter or such dealer retains any Debt
     Securities;

          6.4 As soon as practicable, to make generally available to its
     security holders an earnings statement covering a period of at least twelve
     months beginning after the "effective date of the registration statement"
     within the meaning of Rule 158 under the Act which will satisfy the
     provisions of Section 11(a) of the Act;

          6.5 To pay or bear (i) all expenses in connection with the matters
     herein required to be performed by it, including all expenses (except as
     provided in paragraph 6.3 above) in connection with the preparation and
     filing of the Registration Statement and the Prospectus, and any amendment
     or supplement thereto, and the furnishing of copies thereof to the
     Underwriters, and all audits, statements or reports in connection
     therewith, and all expenses in connection with the original issue and
     delivery of the Debt Securities to the Underwriters at the place designated
     in Section III hereof, and all Federal and State taxes (if any) payable
     (not including any transfer taxes) upon the original issue of the Debt
     Securities, (ii) all expenses in connection with the printing of this
     Agreement; and

                                    Page 8
<PAGE>
 
          6.6 Before amending or supplementing the Registration Statement or the
     Prospectus (to the extent that such amendment or supplement relates to the
     Shares), to furnish to the Representative a copy of each such proposed
     amendment or supplement.

                                  Section VII

     The Company agrees to indemnify and hold harmless each Underwriter and each
person, if any, who controls such Underwriter within the meaning of either
Section 15 of the Securities Act or Section 20 of the Exchange Act from and
against any and all losses, claims, damages and liabilities (including, without
limitation, any legal or other expenses reasonably incurred by any Underwriter
or any such controlling person in connection with defending or investigating any
such action or claim) caused by any untrue statement or alleged untrue statement
of a material fact contained in the Registration Statement or any amendment
thereof, any preliminary prospectus or the Prospectus (as amended or
supplemented if the Company shall have furnished any amendments or supplements
thereto), or caused by any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, except insofar as such losses, claims, damages or
liabilities are caused by any such untrue statement or omission or alleged
untrue statement or omission based upon information relating to any Underwriter
furnished to the Company in writing by such Underwriter through the
Representative expressly for use therein.

     Each Underwriter agrees, severally and not jointly, to indemnify and hold
harmless the Company, its directors, its officers who sign the Registration
Statement and each person, if any, who controls the Company within the meaning
of either Section 15 of the Securities Act or Section 20 of the Exchange Act to
the same extent as the foregoing indemnity from the Company to such Underwriter,
but only with reference to information relating to such Underwriter furnished to
the Company by such Underwriter through the Representative expressly for use in
the Registration Statement, any preliminary prospectus, the Prospectus or any
amendments or supplements thereto.

     In case any proceeding (including any governmental investigation) shall be
instituted involving any person in respect of which indemnity may be sought
pursuant to either of the two preceding paragraphs, such person (the
"indemnified party") shall promptly notify the person against whom such
indemnity may be sought (the "indemnifying party") in writing and the
indemnifying party, upon request of the indemnified party, shall retain counsel
reasonably satisfactory to the indemnified party to represent the indemnified
party and any others the indemnifying party may designate in such proceeding and
shall pay the fees and disbursements of such counsel related to such proceeding.
In any such proceeding, any indemnified party shall have the right to retain its
own counsel, but the fees and expenses of such counsel shall be at the expense
of such indemnified party unless (i) the indemnifying party and the indemnified
party shall have mutually agreed to the retention of such counsel or (iii) the
named parties to any such proceeding (including any impleaded parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them. It is understood that the indemnifying

                                    Page 9
<PAGE>
 
party shall not, in respect of the legal expenses of any indemnified party in
connection with any proceeding or related proceedings in the same jurisdiction,
be liable for the fees and expenses of more than one separate firm (in addition
to any local counsel) for all such indemnified parties and that all such fees
and expenses shall be reimbursed as they are incurred.  Such firm shall be
designated in writing by the Representative, in the case of parties indemnified
pursuant to the second preceding paragraph, and by the Company, in the case of
parties indemnified pursuant to the first preceding paragraph. The indemnifying
party shall not be liable for any settlement of any proceeding effected without
its written consent, but if settled with such consent or if there be a final
judgment for the plaintiff, the indemnifying party agrees to indemnify the
indemnified party from and against any loss or liability by reason of such
settlement or judgment. Notwithstanding the foregoing sentence, if at any time
an indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel as contemplated by the second
and third sentences of this paragraph, the indemnifying party agrees that it
shall be liable for any settlement, of any proceeding effected without its
written consent if (i) such settlement is entered into more than 30 days after
receipt by such indemnifying party of the aforesaid request and (ii) such
indemnifying party shall not have reimbursed the indemnified party in accordance
with such request prior to the date of such settlement.  No indemnifying party
shall, without the prior written consent of the indemnified party, effect any
settlement of any pending or threatened proceeding in respect of which any
indemnified party is or could have been a party and indemnity would have been
sought hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all liability on claims
that are the subject matter of such proceeding.

     If any Underwriter or person shall be entitled to indemnification by the
terms of this Section VII, and if such claim for indemnification is thereafter
held by a court to be unavailable for any reason other than by reason of the
terms of this Section VII or if such claim is unavailable under controlling
precedent, such Underwriter or person shall be entitled to contribution from the
Company to liabilities and expenses, except to the extent that contribution is
not permitted under Section 11(f) of the Securities Act.  In determining the
amount of contribution to which such Underwriter or person is entitled, there
shall be considered the relative benefits received by such Underwriter or person
and the Company from the offering of the Debt Securities (taking into account
the portion of the proceeds of the offering realized by each), the Underwriter's
or person's relative knowledge and access to information concerning the matter
with respect to which the claim was asserted, the opportunity to correct and
prevent any statement or omission, and any other statement or omission, and any
other equitable considerations appropriate under the circumstances. The Company
and the Underwriters agree that it would not be equitable if the amount of such
contribution were determined by pro rata or per capita allocation (even if the
Underwriters were treated as one entity for such purpose).

     The indemnity and contribution provisions contained in this Section VII and
the representations and warranties of the Company contained in this Agreement
shall remain operative and in full force and effect regardless of (i) any
termination of this Agreement, (ii) any investigation made by or on behalf of
any Underwriter or any person controlling any

                                    Page 10
<PAGE>
 
Underwriter or by or on behalf of the Company, its officers or directors or any
person controlling the Company and (iii) acceptance of and payment for any of
the Debentures.

                                 Section VIII

     This Agreement shall be subject to termination by notice given by the
Representative to the Company, if (a) after the execution and delivery of this
Agreement and prior to the Closing Date (i) trading generally shall have been
suspended or materially limited on or by the New York Stock Exchange or the
Nasdaq Stock Market, (ii) trading of any securities of the Company shall have
been suspended on any exchange or in any over-the-counter market, (iii) a
general moratorium on commercial banking activities in New York shall have been
declared by either Federal or New York State authorities or (iv) there shall
have occurred any outbreak or escalation of hostilities or any change in
financial markets or any calamity or crisis that, in the Representative's
reasonable judgment, is material and adverse and (b) in the case of any of the
events specified in clauses (a) (i) through (iv), such event singly or together
with any other such event makes it, in the Representative's reasonable judgment,
impracticable to market the Debt Securities on the terms and in the manner
contemplated in the Prospectus.

                                  Section IX

     This Agreement shall become effective upon the later of execution and
delivery hereof by the parties hereto.

     If, on the Closing Date, any one or more of the Underwriters shall fail or
refuse to purchase Debt Securities that it or they have agreed to purchase
hereunder on such date, and the aggregate principal amount of Debt Securities
which such defaulting Underwriter or Underwriters agreed but failed or refused
to purchase is not more than one-tenth of the aggregate principal amount of the
Debt Securities to be purchased on such date, the other Underwriters shall be
obligated severally in the proportions that the principal amount of Debt
Securities set forth opposite their respective names in Schedule I bears to the
aggregate principal amount of Debt Securities set forth opposite the names of
all such non-defaulting Underwriters, or in such other proportions as the
Representative may specify, to purchase the Debt Securities which such
defaulting Underwriter or Underwriters agreed but failed or refused to purchase
on such date; provided that in no event shall the principal amount of Debt
Securities that any Underwriter has agreed to purchase pursuant to Section II be
increased pursuant to this Section IX by an amount in excess of [one-tenth] of
such principal amount of Debt Securities without the written consent of such
Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail
or refuse to purchase Debt Securities and the aggregate principal amount of Debt
Securities with respect to which such default occurs is more than one-tenth of
the aggregate principal amount of Debt Securities to be purchased on such date,
and arrangements satisfactory to the Company for the purchase of such Debt
Securities are not made within 36 hours after such default, this Agreement shall
terminate without liability on the part of any non-defaulting Underwriter or the
Company. In any such case either the Representative or the Company shall have
the right to postpone the Closing Date, but in no event for longer than seven
days, in order that the required changes, if any, in the Registration Statement
and in the

                                    Page 11
<PAGE>
 
Prospectus or in any other documents or arrangements may be effected.  Any
action taken under this paragraph shall not relieve any defaulting Underwriter
from liability in respect of any default of such Underwriter under this
Agreement.

     If this Agreement shall be terminated by the Underwriters, or any of them,
because of any failure or refusal on the part of the Company to comply with the
terms or to fulfill any of the conditions of this Agreement, or if for any
reason the Company shall be unable to perform its obligations under this
Agreement, the Company will reimburse the Underwriters or such Underwriters as
have so terminated this Agreement with respect to themselves, severally, for all
out-of-pocket expenses (including the fees and disbursements of their counsel)
reasonably incurred by such Underwriters in connection with this Agreement or
the offering contemplated hereunder.

                                    Page 12
<PAGE>
 
     This Agreement may be signed in two or more counterparts, each of which
shall be an original, with the same effect as if the signatures thereto and
hereto were upon the same instrument.

     This Agreement shall be governed by and construed in accordance with the
internal laws of the State of New York.

                                         Very truly yours,

               [FORM OF PREFERRED STOCK UNDERWRITING AGREEMENT]

                                        , 199__


[Representative Name]
[Address]

Ladies and Gentlemen;

     Dominion Resources, Inc., a Virginia corporation (the "Company"), proposes
to issue and sell to the several Underwriters named in Schedule I hereto (the
"Underwriters") for whom you are acting as representative (in such capacity you
shall be referred to as the "Representative"), _______ shares of its Series ___
preferred stock  (the "Firm Shares"). The Company also proposes to issue and
sell to the several Underwriters not more than an additional _______ shares of
such preferred stock  (the "Additional Shares") if and to the extent the
Representative shall have determined to exercise, on behalf of the Underwriters,
the right to purchase such shares of preferred stock granted to the Underwriters
in Section II hereof. The Firm Shares and the Additional Shares are hereinafter
collectively referred to as the Shares. The shares of Series ___ preferred stock
of the Company to be outstanding after giving effect to the sales contemplated
hereby are hereinafter referred to as the Preferred Stock.

     The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3, including a prospectus,
relating to the registration of the Shares and certain of the Company's debt
securities under the Securities Act of 1933, as amended (the "Securities Act"),
and the offering thereof from time to time in accordance with Rule 415 of the
rules and regulations promulgated under the Securities Act (the "Rules and
Regulations").  Such registration statement has been declared effective by the
Commission. The registration statement as amended at the time it became
effective, including the information (if any) deemed to be part of the
registration statement at the time of effectiveness pursuant to Rule 430A or
Rule 434 under the Securities Act of 1933, as amended (the "Securities Act"), 
is hereinafter referred to as the Registration Statement; and the prospectus
(including any prospectus supplement whether or not such prospectus supplement
is required to be filed by the Company pursuant to Rule 424(b) of the Rules and
Regulations) in the form first used to confirm sales of Shares is hereinafter
referred to as the Prospectus (including, in the case of all references to the
Registration Statement and the Prospectus, documents incorporated therein by
reference).

                                   Section I

     1.1  The Company represents and warrants to you and to each of the other
Underwriters as of the date hereof that:
<PAGE>
 
          (a)  The Registration Statement, on the effective date thereof,
     conformed in all material respects to the requirements of the Securities
     Act and the Rules and Regulations and did not include any untrue statement
     of a material fact or omit to state any material fact necessary to make the
     statements therein, in the light of the circumstances under which they were
     made, not misleading, and on the date of this Agreement the Registration
     Statement and the Prospectus conform in all material respects to the
     requirements of the Securities Act and the Rules and Regulations and
     neither of such documents includes any untrue statement of a material fact
     or omits to state any material fact necessary to make the statements
     therein, in the light of the circumstances under which they were made, not
     misleading; provided, however, that the Company makes no representation or 
                 --------  -------                           
     warranty as to the information contained in or omitted from such documents,
     in reliance upon and in conformity with information furnished to the
     Company by or on behalf of the Underwriters through the Representative
     specifically for inclusion therein.

          (b)  The documents incorporated, or deemed to be incorporated, by
     reference in the Prospectus pursuant to Item 12 of the requirements of 
     Form S-3 under the Securities Act, at the time they were or thereafter are
     filed with the Commission, complied, and will comply, in all material
     respects with the applicable requirements of the Exchange Act of 1934, as
     amended (the "Exchange Act"), and the rules and regulations of the
     Commission promulgated thereunder.

          (c)  The Shares have been duly authorized and, when issued and
     delivered in accordance with the terms of this Agreement, will be validly
     issued, fully paid and non-assessable, and the issuance of such Shares will
     not be subject to any preemptive or similar rights.

     1.2  Each of the several Underwriters represents and warrants to, and
agrees with, the Company, its directors and such of its officers as shall have
signed the Registration Statement, and to each other Underwriter, that the
information furnished to the Company by, or through the Representative on behalf
of, such Underwriter expressly for use in the Registration Statement or the
Prospectus does not contain an untrue statement of a material fact and does not
omit to state a material fact in connection with such information required to be
stated therein or necessary to make such information not misleading.

                                  Section II

     The Company hereby agrees to sell to the several Underwriters, and the
Underwriters, upon the basis of the representations and warranties herein
contained, but subject to the conditions hereinafter stated, agree, severally
and not jointly, to purchase from the Company the respective numbers of Firm
Shares set forth in Schedule I hereto opposite their names at $______ a share
(the "Purchase Price").

                                     Page 2
<PAGE>
 
     On the basis of the representations and warranties contained in this
Agreement, and subject to its terms and conditions, the Company agrees to sell
to the Underwriters the Additional Shares, and the Underwriters shall have a
one-time right to purchase, severally and not jointly, up to ________ Additional
Shares at the Purchase Price. Additional Shares may be purchased as provided in
Section IV hereof solely for the purpose of covering over-allotments made in
connection with the offering of the Firm Shares. If any Additional Shares are to
be purchased, each Underwriter agrees, severally and not jointly, to purchase
the number of Additional Shares (subject to such adjustments to eliminate
fractional shares as the Representative may determine) that bears approximately
the same proportion to the total number of Additional Shares to be purchased as
the number of Firm Shares set forth in Schedule I hereto opposite the name of
such Underwriter bears to the total number of Firm Shares.

     The Company hereby agrees that, without the prior written consent of the
Representative, it will not (i) offer, sell, contract to sell, sell any option
or contract to purchase, purchase any option or contract to sell, grant any
option, right or warrant to purchase or otherwise transfer or dispose of,
directly or indirectly, or to register or announce the sale or offering of any
shares of Preferred Stock or any securities convertible into or exercisable or
exchangeable for such Preferred Stock or (ii) enter into any agreement that
transfers, in whole or in part, the economic consequences of ownership of such
Preferred Stock, whether any such transaction described in clause (i) or (ii)
above is to be settled by delivery of such Preferred Stock or such other
securities in cash or otherwise, for a period of 60 days after the date of the
initial public offering of the Shares, other than the Shares to be sold
hereunder.

                                  Section III

     The Company is advised by the Representative that the Underwriters propose
to make a public offering of their respective portions of the Shares as soon
after the Registration Statement and this Agreement have become effective as in
the Representative's judgement is advisable. The Company is further advised by
the Representative that the Shares are to be offered to the public initially at
$________ a share (the "Public Offering Price") and to certain dealers selected
by the Representative at a price that represents a concession not in excess of
$________ a share under the Public Offering Price, and that any Underwriter may
allow, and such dealers may reallow, a concession, not in excess of $________ a
share, to any Underwriter or to certain other dealers.

                                  Section IV

     Payment for the Firm Shares shall be made by or on behalf of the several
Underwriters by the wire transfer of immediately available funds to the
Company's account listed on Schedule II to this Agreement.  Such payment shall
be made upon delivery of the Firm Shares to the Representative or upon its order
at the office of the Representative, [Address], at 10:00 A.M., New York City
time, on the third business day (unless postponed in accordance with the
provisions of Section IX) following the date of this Agreement, or if pricing
takes place after 4:30 P.M. New York City time, on the fourth business day
following the date of this Agreement

                                     Page 3
<PAGE>
 
(unless postponed in accordance with the provisions of Section IX), or at such
other time on the same or such other earlier date, as shall be agreed upon by
the Representative and the Company. The time and date of such payment are
hereinafter referred to as the Closing Date.

     Payment for any Additional Shares shall be made by or on behalf of the
several Underwriters by the wire transfer of immediately available funds to the
Company's account listed on Schedule II to this Agreement. Such payment shall
be made upon delivery of the Additional Shares to the Representative or upon its
order at the office of the Representative, [Address], at 10:00 A.M., New York
City time, on such date (which may be the same as the Closing Date but shall in
no event be earlier than the Closing Date nor later than ten business days after
the giving of the notice hereinafter referred to) as shall be designated in a
written notice from the Representative to the Company of the Representative's
determination, on behalf of the Underwriters, to purchase a number, specified in
said notice, of Additional Shares, or on such other date, in any event not later
than ______ 199__, as shall be agreed upon by the Representative and the
Company. The time and date of such payment are hereinafter referred to as the
Option Closing Date.  The notice of the determination to exercise the option to
purchase Additional Shares and of the Option Closing Date may be given at any
time within 30 days after the date of this Agreement.

     Certificates for the Firm Shares and Additional Shares shall be in
definitive form and registered in such names and in such denominations as the
Representative shall request in writing not later than one full business day
prior to the Closing Date or the Option Closing Date, as the case may be.  The
certificates evidencing the Firm Shares and Additional Shares shall be delivered
to the Representative on the Closing Date or the Option Closing Date, as the
case may be, for the respective accounts of the several Underwriters, with any
transfer taxes payable in connection with the transfer of the Shares to the
Underwriters duly paid, against payment of the Purchase Price therefor.

                                   Section V

     The several obligations of the Underwriters hereunder are subject to the
following further conditions:

          5.1  If the Company does not elect to rely on Rule 434 under the
     Rules and Regulations, and if the filing of the Prospectus is required
     pursuant to Rule 424(b), the Prospectus (including a prospectus supplement)
     shall have been filed with the Commission in the manner and within the time
     period required by Rule 424(b); and prior to the Closing Date, no stop
     order suspending the effectiveness of the Registration Statement shall have
     been issued and no proceedings for that purpose shall have been instituted,
     or, to the knowledge of the Company, shall be contemplated by the
     Commission and the Representative shall have received at such closing a
     certificate of the Company, dated the Closing Date, to such effect. If the
     Company elects to rely on Rule 434 under the Rules and Regulations,
     immediately following the execution of this Agreement, the Company will
     prepare an abbreviated term sheet that complies with the

                                     Page 4
<PAGE>
 
     requirements of Rule 434 under the Rules and Regulations and will provide
     the Underwriters with copies of the form of Rule 434 Prospectus, in such
     number as the Representative shall reasonably request, and if necessary,
     promptly file or transmit for filing with the Commission the form of
     Prospectus complying with Rule 434(c)(2) of the Rules and Regulations in
     accordance with Rule 424(b) thereunder.

          5.2  Subsequent to the execution and delivery of this Agreement and
     prior to the Closing Date, there shall not have occurred any material
     adverse change in the condition, financial or otherwise, or in the
     earnings, business or operations, of the Company and its subsidiaries,
     taken as a whole, from that set forth in the Registration Statement.

          5.3  The Representative shall have received a certificate, dated
     the Closing Date, of the Chairman of the Board, President and Chief
     Executive Officer or any Executive Vice President, Senior Vice President or
     Vice President of the Company, in which such officer, to the best of his
     knowledge, shall state that (i) the representations and warranties of the
     Company in this Agreement are true and correct (except for immaterial
     details) as of the Closing Date and (ii) subsequent to the date of the
     latest financial statements in the Prospectus, there has been no material
     adverse change in the financial position or results of operations of the
     Company except as set forth or contemplated in the Prospectus or as
     described in such certificate.

          5.4  You shall have received on the Closing Date an opinion of
     Thomas F. Farrell, II, Esq., Senior Vice President - Corporate Affairs or
     such other counsel for the Company, as may be acceptable to the
     Representative, dated the Closing Date, to the effect that:

          (a)    The Company has been duly incorporated and is an existing
          corporation in good standing under the laws of the Commonwealth of
          Virginia, with corporate power and authority to own, lease and operate
          its properties and conduct its business as described in the
          Prospectus; and the Company is duly qualified to do business as a
          foreign corporation in good standing in all other jurisdictions in
          which it owns or leases substantial properties or in which the conduct
          of its business requires such qualification except where the failure
          to so qualify or be in good standing would not have a material adverse
          effect on the Company and its subsidiaries, considered as one
          enterprise;

          (b)    Each significant subsidiary as defined in Rule 405 of
          Regulation C of the Securities Act (each a "Significant Subsidiary")
          of the Company has been duly incorporated and is validly existing as a
          corporation in good standing under the laws of the jurisdiction of its
          incorporation, has corporate power and authority to own, lease and
          operate its properties and conduct its business as described in the
          Prospectus; and, to the best of such counsel's knowledge, is duly
          qualified as a foreign corporation to transact business and is in good
          standing in each jurisdiction in which such qualification is required,
          except where the failure to so

                                     Page 5
<PAGE>
 
          qualify or be in good standing would not have a material adverse
          effect on the Company and its subsidiaries, considered as one
          enterprise; all of the issued and outstanding capital stock of each
          Significant Subsidiary has been duly authorized and validly issued, is
          fully paid and nonassessable, and, except for directors' qualifying
          shares, if any, is owned by the Company free and clear of any
          mortgage, pledge, lien, encumbrance, claim or equity;

          (c)    No consent, approval, authorization or order of, or filing
          with, any governmental agency or body or any court is required for the
          consummation of the transactions contemplated herein, except such as
          may be required under the Securities Act or state securities laws; and

          (d)    The execution, delivery and performance of this Agreement and
          the issuance and sale of the Shares and compliance with the terms and
          provisions thereof will not result in a material breach or violation
          of any of the terms and provisions of, or constitute a default under,
          any statute, rule, regulation or order of any governmental agency or
          body or any court having jurisdiction over the Company or any
          Significant Subsidiary or any of their properties or, to the best of
          such counsel's knowledge, any agreement or instrument to which the
          Company or any of its Significant Subsidiaries is a party or by which
          the Company or any Significant Subsidiary is bound or to which any of
          the properties of the Company or any Significant Subsidiary is
          subject, or the articles of incorporation or bylaws of the Company or
          any Significant Subsidiary, and the Company has full power and
          authority to authorize, issue and sell the Shares as contemplated by
          this Agreement.

          In addition, such counsel shall state that he or she has participated
in conferences with officers and other representatives of the Company,
representatives of Deloitte & Touche LLP, independent auditors for the Company,
and the Representative, at which the contents of the Prospectus and any
amendment thereof or supplement thereto and related matters were discussed and
although such counsel has not undertaken to investigate or verify independently,
and does not assume any responsibility for the accuracy, completeness or
fairness of the statements contained in the Prospectus or any amendment thereof
or supplement thereto, no facts have come to the attention of such counsel which
would lead such counsel to believe that at the date of this Agreement, the
Prospectus (other than the historical, proforma, projected or other financial
statements, information and data and statistical information and data included
or incorporated by reference therein, in each case as to which no opinion need
be given) contained any untrue statement of a material fact or omitted to state
any material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading or that the Prospectus
(other than the historical, proforma, projected or other financial statements,
information and data and statistical information and data included or
incorporated by reference therein, in each case as to which no opinion need be
given) at the Closing Date includes any untrue statement of a material fact or
omits to state a 

                                     Page 6
<PAGE>
 
material fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading.  Except as
otherwise set forth herein, all references in this Section 5.4 to the Prospectus
shall be deemed to include any amendment or supplement thereto at the Closing
Date.

     5.5  The Representative shall have received on the Closing Date an opinion
of McGuire, Woods, Battle & Boothe, L.L.P. counsel for the Company dated the
Closing Date, to the effect that:

     (a)     The Shares have been duly authorized, executed, issued and
     delivered by the Company and constitute valid and legally binding
     obligations of the Company enforceable against the Company 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; and the Shares conform to the description thereof contained in
     the Prospectus;

     (b)     This Agreement has been duly authorized, executed and delivered by
     the Company;

     In addition, subject to such counsel's customary qualifications about the
scope of its obligations in connection with its participation in the preparation
of documents, such counsel shall state that they have participated in
conferences with officers and other representatives of the Company,
representatives of Deloitte & Touche LLP, independent auditors for the Company,
the Representative, and Counsel for the Underwriters at which the contents of
the Prospectus and any amendment thereof or supplement thereto and related
matters were discussed and although such counsel have not undertaken to
investigate or verify independently, and do not assume any responsibility for
the accuracy, completeness or fairness of the statements contained in the
Prospectus or any amendment thereof or supplement thereto, and did not
participate in the preparation of the documents incorporated by reference in the
Prospectus, no facts have come to the attention of such counsel which would lead
such counsel to believe that at the date of this Agreement, the Prospectus
(other than the historical, proforma, projected or other financial statements,
information and data and statistical information and data included or
incorporated by reference therein, in each case as to which no opinion need be
given) contained any untrue statement of a material fact or omitted to state any
material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading, or that the Prospectus
at the applicable Closing Date (other than the historical, proforma, projected
or other financial statements, information and data and statistical information
and data included or incorporated by reference therein, in each case as to which
no opinion need be given) includes any untrue statement of a material fact or
omits to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading.

                                     Page 7
<PAGE>
 
          In rendering such opinion, McGuire, Woods, Battle & Boothe, L.L.P. may
     rely (A) as to matters governed by New York law upon the opinion of Counsel
     for the Underwriters, referred to below and (B) as to matters of fact, to
     the extent they deem proper, on certificates of responsible officers of the
     Company and public officials. Except as otherwise set forth herein, all
     references in this Section 5.5 to the Prospectus shall be deemed to include
     any amendment or supplement thereto at the applicable Closing Date.

          The opinion of McGuire, Woods, Battle & Boothe, L.L.P. shall be
     rendered to the Representative at the request of the Company and shall so
     state therein.

          5.6  The Representative shall have received from [Underwriters'
     Counsel], counsel for the Underwriters, such opinion or opinions, dated the
     Closing Date, with respect to the validity of the Shares, the Registration
     Statement, the Prospectus, this Agreement and other related matters as the
     Representative may reasonably request, and the Company shall have furnished
     to such counsel such documents as they reasonably request for the purpose
     of enabling them to pass upon such matters. In rendering such
     opinion,[Underwriters' Counsel] may rely as to matters governed by Virginia
     law upon the opinion of Thomas F. Farrell Esq. or such other counsel
     referred to in paragraph 5.4 above.

          5.7  On the Closing Date, the Representative shall have received from
     Deloitte & Touche LLP a letter dated such date, in form and substance
     satisfactory to the Representative.

     The several obligations of the Underwriters to purchase Additional Shares
hereunder are subject to the delivery to the Representative on the Option
Closing Date of such documents and opinions as the Representative may reasonably
request with respect to the good standing of the Company, the due authorization
and issuance of the Additional Shares and other matters related to the issuance
of the Additional Shares.

                                  Section VI

     The obligations of the Company to sell and deliver the Shares on the
Closing Date are subject to the condition that at the Closing Date, no stop
order suspending the effectiveness of the Registration Statement shall be in
effect or proceeding therefor shall have been instituted or, to the knowledge of
the Company, shall be contemplated.

     If the foregoing condition shall not have been satisfied, then the Company
shall be entitled, by notice in writing or by telegram to the Representative, to
terminate this Agreement without any liability on the part of the Company or any
Underwriter, except as provided in paragraphs 7.1 and 7.5 hereof.

                                  Section VII

                                     Page 8
<PAGE>
 
     In further consideration of the agreements of the Underwriters herein
contained, the Company covenants as follows:

          7.1  To assist in any required qualification of the Shares by the
     Representative or on its behalf for offer and sale under the securities or
     blue sky laws of such States as the Representative may designate, to
     continue such qualification in effect so long as required for the
     distribution of the Shares and to reimburse the Representative for any
     expenses (including filing fees and fees and disbursements of counsel) paid
     by the Representative or on its behalf to qualify the Shares for offer and
     sale, to continue such qualification, to determine the eligibility of the
     Shares for investment and to print the memoranda relating thereto; provided
     that the Company shall not be required to qualify as a foreign corporation
     in any jurisdiction in which it is not so qualified;

          7.2  Promptly to deliver to the Representative conformed copies of
     the Registration Statement (including all documents incorporated by
     reference therein) as originally filed and of all amendments thereto
     heretofore or hereafter filed, including conformed copies of all exhibits
     except those incorporated by reference, and such number of copies
     of the Registration Statement (but excluding the exhibits), each related
     preliminary prospectus, the Prospectus, and any amendments and supplements
     thereto, as the Representative may reasonably request;

          7.3  If, at any time when a prospectus relating to the Shares is
     required to be delivered under the Securities Act in connection with sales
     by an Underwriter or dealer, any event occurs as a result of which the
     Prospectus as then amended or supplemented would include an untrue
     statement of a material fact or omit to state any material fact necessary
     to make the statements therein, in the light of the circumstances under
     which they were made, not misleading, or if it is necessary at any time to
     amend the Prospectus to comply with the Securities Act in connection with
     sales by an Underwriter or dealer, to advise the Representative of such
     event or necessity, as the case may be, and, promptly upon request made by
     the Representative, to prepare and file with the Commission an amendment or
     supplement which will correct such statement or omission or an amendment
     which will effect such compliance; provided that the expense of preparing
     and filing and such amendment or supplement (i) which is necessary in
     connection with such a delivery of a prospectus more than nine months after
     the date of this Agreement or (ii) which relates solely to the activities
     of any Underwriter shall be borne by the Underwriter or Underwriters or the
     dealer or dealers requiring the same; and provided further that the
     Representative shall, upon inquiry by the Company, advise the Company
     whether or not any Underwriter or dealer which shall have been selected by
     the Representative retains any unsold Shares and, for the purposes of this
     paragraph 7.4, the Company shall be entitled to assume that the
     distribution of the Shares has been completed when it is advised by the
     Representative that no Underwriter or such dealer retains any Shares;

          7.4  As soon as practicable, to make generally available to its
     security holders an earnings statement covering a period of at least twelve
     months beginning after the "effective date of the registration statement"
     within the meaning of Rule 158 under the Act which will satisfy the
     provisions of Section 11(a) of the Act;

          7.5  To pay or bear (i) all expenses in connection with the matters
     herein required to be performed by it, including all expenses (except as
     provided in paragraph 7.3 above) in connection with the preparation and
     filing of the Registration Statement and the Prospectus, and any amendment
     or supplement thereto, and the furnishing of copies thereof to the
     Underwriters, and all audits, statements or reports in connection
     therewith, and all expenses in connection with the original issue and
     delivery of the Shares to the 

                                     Page 9
<PAGE>
 
     Underwriters at the place designated in Section IV hereof, and all Federal
     and State taxes (if any) payable (not including any transfer taxes) upon
     the original issue of the Shares, (ii) all expenses in connection with the
     printing of this Agreement; and

          7.6  Before amending or supplementing the Registration Statement or
     the Prospectus (to the extent that such amendment or supplement relates to
     the Shares), to furnish to the Representative a copy of each such proposed
     amendment or supplement.

                                 Section VIII

     The Company agrees to indemnify and hold harmless each Underwriter and each
person, if any, who controls such Underwriter within the meaning of either
Section 15 of the Securities Act or Section 20 of the Exchange Act from and
against any and all losses, claims, damages and liabilities (including, without
limitation, any legal or other expenses reasonably incurred by any Underwriter
or any such controlling person in connection with defending or investigating any
such action or claim) caused by any untrue statement or alleged untrue statement
of a material fact contained in the Registration Statement or any amendment
thereof, any preliminary prospectus or the Prospectus (as amended or
supplemented if the Company shall have furnished any amendments or supplements
thereto), or caused by any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, except insofar as such losses, claims, damages or
liabilities are caused by any such untrue statement or omission or alleged
untrue statement or omission based upon information relating to any Underwriter
furnished to the Company in writing by such Underwriter through the
Representative expressly for use therein.

     Each Underwriter agrees, severally and not jointly, to indemnify and hold
harmless the Company, its directors, its officers who sign the Registration
Statement and each person, if any, who controls the Company within the meaning
of either Section 15 of the Securities Act or Section 20 of the Exchange Act to
the same extent as the foregoing indemnity from the Company to such Underwriter,
but only with reference to information relating to such Underwriter furnished to
the Company by such Underwriter through the Representative expressly for use in
the Registration Statement, any preliminary prospectus, the Prospectus or any
amendments or supplements thereto.

     In case any proceeding (including any governmental investigation) shall be
instituted involving any person in respect of which indemnity may be sought
pursuant to either of the two preceding paragraphs, such person (the
"indemnified party") shall promptly notify the person against whom such
indemnity may be sought (the "indemnifying party") in writing and the
indemnifying party, upon request of the indemnified party, shall retain counsel
reasonably satisfactory to the indemnified party to represent the indemnified
party and any others the indemnifying party may designate in such proceeding and
shall pay the fees and disbursements of such counsel related to such proceeding.
In any such proceeding, any indemnified party shall have the right to retain its
own counsel, but the fees and expenses of such counsel shall be at the expense
of such indemnified party unless (i) the indemnifying party and the indemnified
party

                                    Page 10
<PAGE>
 
shall have mutually agreed to the retention of such counsel or (iii) the named
parties to any such proceeding (including any impleaded parties) include both
the indemnifying party and the indemnified party and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them. It is understood that the indemnifying party
shall not, in respect of the legal expenses of any indemnified party in
connection with any proceeding or related proceedings in the same jurisdiction,
be liable for the fees and expenses of more than one separate firm (in addition
to any local counsel) for all such indemnified parties and that all such fees
and expenses shall be reimbursed as they are incurred.  Such firm shall be
designated in writing by the Representative, in the case of parties indemnified
pursuant to the second preceding paragraph, and by the Company, in the case of
parties indemnified pursuant to the first preceding paragraph. The indemnifying
party shall not be liable for any settlement of any proceeding effected without
its written consent, but if settled with such consent or if there be a final
judgment for the plaintiff, the indemnifying party agrees to indemnify the
indemnified party from and against any loss or liability by reason of such
settlement or judgment. Notwithstanding the foregoing sentence, if at any time
an indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel as contemplated by the second
and third sentences of this paragraph, the indemnifying party agrees that it
shall be liable for any settlement, of any proceeding effected without its
written consent if (i) such settlement is entered into more than 30 days after
receipt by such indemnifying party of the aforesaid request and (ii) such
indemnifying party shall not have reimbursed the indemnified party in accordance
with such request prior to the date of such settlement.  No indemnifying party
shall, without the prior written consent of the indemnified party, effect any
settlement of any pending or threatened proceeding in respect of which any
indemnified party is or could have been a party and indemnity would have been
sought hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all liability on claims
that are the subject matter of such proceeding.

     If any Underwriter or person shall be entitled to indemnification by the
terms of this Section VIII, and if such claim for indemnification is thereafter
held by a court to be unavailable for any reason other than by reason of the
terms of this Section VIII or if such claim is unavailable under controlling
precedent, such Underwriter or person shall be entitled to contribution from the
Company to liabilities and expenses, except to the extent that contribution is
not permitted under Section 11(f) of the Securities Act.  In determining the
amount of contribution to which such Underwriter or person is entitled, there
shall be considered the relative benefits received by such Underwriter or person
and the Company from the offering of the Shares (taking into account the portion
of the proceeds of the offering realized by each), the Underwriter's or person's
relative knowledge and access to information concerning the matter with respect
to which the claim was asserted, the opportunity to correct and prevent any
statement or omission, and any other statement or omission, and any other
equitable considerations appropriate under the circumstances.  The Company and
the Underwriters agree that it would not be equitable if the amount of such
contribution were determined by pro rata or per capita allocation (even if the
Underwriters were treated as one entity for such purpose).

                                    Page 11
<PAGE>
 
     The indemnity and contribution provisions contained in this Section VIII
and the representations and warranties of the Company contained in this
Agreement shall remain operative and in full force and effect regardless of (i)
any termination of this Agreement, (ii) any investigation made by or on behalf
of any Underwriter or any person controlling any Underwriter or by or on behalf
of the Company, its officers or directors or any person controlling the Company
and (iii) acceptance of and payment for any of the Shares.

                                   Section IX

     This Agreement shall be subject to termination by notice given by the
Representative to the Company, if (a) after the execution and delivery of this
Agreement and prior to the Closing Date (i) trading generally shall have been
suspended or materially limited on or by the New York Stock Exchange or the
Nasdaq Stock Market, (ii) trading of any securities of the Company shall have
been suspended on any exchange or in any over-the-counter market, (iii) a
general moratorium on commercial banking activities in New York shall have been
declared by either Federal or New York State authorities or (iv) there shall
have occurred any outbreak or escalation of hostilities or any change in
financial markets or any calamity or crisis that, in the Representative's
reasonable judgment, is material and adverse and (b) in the case of any of the
events specified in clauses (a) (i) through (iv), such event singly or together
with any other such event makes it, in the Representative's reasonable judgment,
impracticable to market the Shares on the terms and in the manner contemplated
in the Prospectus.

                                   Section X

     This Agreement shall become effective upon the later of (x) execution and
delivery hereof by the parties hereto or (y) release of notification of the
effectiveness of the Registration Statement by the Commission.

     If, on the Closing Date or the Option Closing Date, as the case may be, any
one or more of the Underwriters shall fail or refuse to purchase Shares that it
or they have agreed to purchase hereunder on such date, and the aggregate number
of Shares which such defaulting Underwriter or Underwriters agreed but failed or
refused to purchase is not more than one-tenth of the aggregate number of the
Shares to be purchased on such date, the other Underwriters shall be obligated
severally in the proportions that the number of Firm Shares set forth opposite
their respective names in Schedule I bears to the aggregate number of Firm
Shares set forth opposite the names of all such non-defaulting Underwriters, or
in such other proportions as the Representative may specify, to purchase the
Shares which such defaulting Underwriter or Underwriters agreed but failed or
refused to purchase on such date; provided that in no event shall the number of
Shares that any Underwriter has agreed to purchase pursuant to Section II be
increased pursuant to this Section X by an amount in excess of [one-ninth] of
such number of Shares without the written consent of such Underwriter.  If, on
the Closing Date or the Option Closing Date, as the case may be, any Underwriter
or Underwriters shall fail or refuse to purchase Shares and the aggregate number
of Shares with respect to which such default occurs is more than one-tenth of
the aggregate number of Shares to be purchased on such date, and

                                    Page 12
<PAGE>
 
arrangements satisfactory to the Company for the purchase of such Shares are not
made within [36] hours after such default, this Agreement shall terminate
without liability on the part of any non-defaulting Underwriter or the Company.
In any such case either the Representative or the Company shall have the right
to postpone the Closing Date or the Option Closing Date, as the case may be, but
in no event for longer than [seven] days, in order that the required changes, if
any, in the Registration Statement and in the Prospectus or in any other
documents or arrangements may be effected.  Any action taken under this
paragraph shall not relieve any defaulting Underwriter from liability in respect
of any default of such Underwriter under this Agreement.

     If this Agreement shall be terminated by the Underwriters, or any of them,
because of any failure or refusal on the part of the Company to comply with the
terms or to fulfill any of the conditions of this Agreement, or if for any
reason the Company shall be unable to perform its obligations under this
Agreement, the Company will reimburse the Underwriters or such Underwriters as
have so terminated this Agreement with respect to themselves, severally, for all
out-of-pocket expenses (including the fees and disbursements of their counsel)
reasonably incurred by such Underwriters in connection with this Agreement or
the offering contemplated hereunder.

                                    Page 13

     This Agreement may be signed in two or more counterparts, each of which

[Representative Name]
[Address]

Ladies and Gentlemen;

     Dominion Resources, Inc., a Virginia corporation (the "Company"), proposes
to issue and sell to the several Underwriters named in Schedule I hereto (the
"Underwriters") for whom you are acting as representative (in such capacity you
shall be referred to as the "Representative"), _______ shares of its common
stock (no par value) (the "Firm Shares"). The Company also proposes to issue and
sell to the several Underwriters not more than an additional _______ shares of
its common stock (no par value) (the "Additional Shares") if and to the extent
the Representative shall have determined to exercise, on behalf of the
Underwriters, the right to purchase such shares of common stock granted to the
Underwriters in Section II hereof. The Firm Shares and the Additional Shares are
hereinafter collectively referred to as the Shares. The shares of common stock
(no par value) of the Company to be outstanding after giving effect to the sales
contemplated hereby are hereinafter referred to as the Common Stock.

     The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3, including a prospectus,
relating to the registration of the Shares and certain of the Company's debt
securities under the Securities Act of 1933, as amended, (the "Securities Act"),
and the offering thereof from time to time in accordance with Rule 415 of the
rules and regulations promulgated under the Securities Act (the "Rules and
Regulations"). Such registration statement has been declared effective by the
Commission. The registration statement, at the time it became effective,
including the information (if any) deemed to be part of the registration
statement at the time of effectiveness pursuant to Rule 430A or Rule 434 under
the Securities Act of 1933, as amended (the "Securities Act"), is hereinafter
referred to as the Registration Statement; and the prospectus (including any
prospectus supplement whether or not such prospectus supplement is required to
be filed by the Company pursuant to Rule 424(b) of the Rules and Regulations) in
the form first used to confirm sales of Shares is hereinafter referred to as the
Prospectus (including, in the case of all references to the Registration
Statement and the Prospectus, documents incorporated therein by reference).

                                   Section I

     1.1 The Company represents and warrants to you and to each of the other
Underwriters as of the date hereof that:
<PAGE>
 
            (a) The Registration Statement, on the effective date thereof,
     conformed in all material respects to the requirements of the Securities
     Act and the Rules and Regulations and did not include any untrue statement
     of a material fact or omit to state any material fact necessary to make the
     statements therein, in the light of the circumstances under which they were
     made, not misleading, and on the date of this Agreement the Registration
     Statement and the Prospectus conform in all material respects to the
     requirements of the Securities Act and the Rules and Regulations and
     neither of such documents includes any untrue statement of a material fact
     or omits to state any material fact necessary to make the statements
     therein, in the light of the circumstances under which they were made, not
     misleading; provided, however, that the Company makes no representation or
                 --------  -------
     warranty as to the information contained in or omitted from such documents,
     in reliance upon and in conformity with information furnished to the
     Company by or on behalf of the Underwriters through the Representative
     specifically for inclusion therein.

            (b) The documents incorporated, or deemed to be incorporated, by
     reference in the Prospectus pursuant to Item 12 of the requirements of Form
     S-3 under the Securities Act, at the time they were or hereafter are filed
     with the Commission, complied, and will comply, in all material respects
     with the applicable requirements of the Exchange Act of 1934, as amended
     (the "Exchange Act"), and the rules and regulations of the Commission
     promulgated thereunder.

            (c) The Shares have been duly authorized and, when issued and
     delivered in accordance with the terms of this Agreement, will be validly
     issued, fully paid and non-assessable, and the issuance of such Shares will
     not be subject to any preemptive or similar rights.

            (d) The Common Stock (other than the Shares) is, and upon issuance
     the Shares will be, listed on the New York Stock Exchange.

     1.2 Each of the several Underwriters represents and warrants to, and
agrees with, the Company, its directors and such of its officers as shall have
signed the Registration Statement, and to each other Underwriter, that the
information furnished to the Company by, or through the Representative on behalf
of, such Underwriter expressly for use in the Registration Statement or the
Prospectus does not contain an untrue statement of a material fact and does not
omit to state a material fact in connection with such information required to be
stated therein or necessary to make such information not misleading.

                                   Section II

     The Company hereby agrees to sell to the several Underwriters, and the
Underwriters, upon the basis of the representations and warranties herein
contained, but subject to the conditions hereinafter stated, agree, severally
and not jointly, to purchase from the Company the

                                     Page 2
<PAGE>
 
respective numbers of Firm Shares set forth in Schedule I hereto opposite their
names at $______ a share (the "Purchase Price").

     On the basis of the representations and warranties contained in this
Agreement, and subject to its terms and conditions, the Company agrees to sell
to the Underwriters the Additional Shares, and the Underwriters shall have a
one-time right to purchase, severally and not jointly, up to ________ Additional
Shares at the Purchase Price. Additional Shares may be purchased as provided in
Section IV hereof solely for the purpose of covering over-allotments made in
connection with the offering of the Firm Shares. If any Additional Shares are to
be purchased, each Underwriter agrees, severally and not jointly, to purchase
the number of Additional Shares (subject to such adjustments to eliminate
fractional shares as the Representative may determine) that bears approximately
the same proportion to the total number of Additional Shares to be purchased as
the number of Firm Shares set forth in Schedule I hereto opposite the name of
such Underwriter bears to the total number of Firm Shares.

     The Company hereby agrees that, without the prior written consent of the
Representative, it will not (i) offer, sell, contract to sell, sell any option
or contract to purchase, purchase any option or contract to sell, grant any
option, right or warrant to purchase or otherwise transfer or dispose of,
directly or indirectly, or to register or announce the sale or offering of any
shares of common stock of the Company or any securities convertible into or
exercisable or exchangeable for such common stock or (ii) enter into any
agreement that transfers, in whole or in part, the economic consequences of
ownership of such common stock, whether any such transaction described in clause
(i) or (ii) above is to be settled by delivery of such common stock or such
other securities in cash or otherwise, for a period of 60 days after the date of
the initial public offering of the Shares, other than (a) the Shares to be sold
hereunder and (b) common stock or options to purchase common stock under the DRI
Subsidiary Savings Plan, Dominion Resources Inc. Incentive Compensation Plan,
Dominion Resources Inc. Stock Accumulation Plan for Outside Directors, Dominion
Direct Investment and Dominion Resources, Inc. Employee Savings Plan in amounts
and on terms consistent with those plans.

                                  Section III

     The Company is advised by the Representative that the Underwriters propose
to make a public offering of their respective portions of the Shares as soon
after the Registration Statement and this Agreement have become effective as in
the Representative's judgement is advisable. The Company is further advised by
the Representative that the Shares are to be offered to the public initially at
$________ a share (the "Public Offering Price") and to certain dealers selected
by the Representative at a price that represents a concession not in excess of
$________ a share under the Public Offering Price, and that any Underwriter may
allow, and such dealers may reallow, a concession, not in excess of $________ a
share, to any Underwriter or to certain other dealers.

     Commission the form of Prospectus complying with Rule 434(c)(2) of the
     Rules and Regulations in accordance with Rule 424(b) thereunder.

           5.2 Subsequent to the execution and delivery of this Agreement and

           Prospectus; and the Company is duly qualified to do business as a
           foreign corporation in good standing in all other jurisdictions in
           which it owns or leases substantial properties or in which the
           conduct of its business requires such qualification except where the
           failure to so qualify or be in good standing would not have a
           material adverse effect on the Company and its subsidiaries,
           considered as one enterprise;

                                     Page 5
<PAGE>
 
           (b)   Each significant subsidiary as defined in Rule 405 of
           Regulation C of the Securities Act (each a "Significant Subsidiary")
           of the Company has been duly incorporated and is validly existing as
           a corporation in good standing under the laws of the jurisdiction of
           its incorporation, has corporate power and authority to own, lease
           and operate its properties and conduct its business as described in
           the Prospectus; and, to the best of such counsel's knowledge, is duly
           qualified as a foreign corporation to transact business and is in
           good standing in each jurisdiction in which such qualification is
           required, except where the failure to so qualify or be in good
           standing would not have a material adverse effect on the Company and
           its subsidiaries, considered as one enterprise; all of the issued and
           outstanding capital stock of each Significant Subsidiary has been
           duly authorized and validly issued, is fully paid and nonassessable,
           and, except for directors' qualifying shares, if any, is owned by the
           Company free and clear of any mortgage, pledge, lien, encumbrance,
           claim or equity;

           (c)   No consent, approval, authorization or order of, or filing
           with, any governmental agency or body or any court is required for
           the consummation of the transactions contemplated herein, except such
           as may be required under the Securities Act or state securities laws;
           and

           (d)   The execution, delivery and performance of this Agreement and
           the issuance and sale of the Shares and compliance with the terms and
           provisions thereof will not result in a material breach or violation
           of any of the terms and provisions of, or constitute a default under,
           any statute, rule, regulation or order of any governmental agency or
           body or any court having jurisdiction over the Company or any
           Significant Subsidiary or any of their properties or, to the best of
           such counsel's knowledge, any agreement or instrument to which the
           Company or any of its Significant Subsidiaries is a party or by which
           the Company or any Significant Subsidiary is bound or to which any of
           the properties of the Company or any Significant Subsidiary is
           subject, or the articles of incorporation or bylaws of the Company or
           any Significant Subsidiary, and the Company has full power and
           authority to authorize, issue and sell the Shares as contemplated by
           this Agreement.

           In addition, such counsel shall state that he or she has participated
     in conferences with officers and other representatives of the Company,
     representatives of Deloitte & Touche LLP, independent auditors for the
     Company, and the Representative, at which the contents of the Prospectus
     and any amendment thereof or supplement thereto and related matters were
     discussed and although such counsel has not undertaken to investigate or
     verify independently, and does not assume any responsibility for the
     accuracy, completeness or fairness of the statements contained in the
     Prospectus or any amendment thereof or supplement thereto, no facts have
     come to the attention of such counsel which would lead such counsel to
     believe that at the date of this Agreement, the Prospectus (other than the
     historical, proforma, projected or other financial statements, information

                                     Page 6
<PAGE>
 
     and data and statistical information and data included or incorporated by
     reference therein, in each case as to which no opinion need be given)
     contained any untrue statement of a material fact or omitted to state any
     material fact necessary to make the statements therein, in the light of the
     circumstances under which they were made, not misleading or that the
     Prospectus (other than the historical, proforma, projected or other
     financial statements, information and data and statistical information and
     data included or incorporated by reference therein, in each case as to
     which no opinion need be given) at the Closing Date includes any untrue
     statement of a material fact or omits to state a material fact necessary in
     order to make the statements therein, in the light of the circumstances
     under which they were made, not misleading. Except as otherwise set forth
     herein, all references in this Section 5.4 to the Prospectus shall be
     deemed to include any amendment or supplement thereto at the Closing Date.

           5.5 The Representative shall have received on the Closing Date an
     opinion of McGuire, Woods, Battle & Boothe, L.L.P. counsel for the Company
     dated the Closing Date, to the effect that:

           (a)   The Shares have been duly authorized, executed, issued and
           delivered by the Company and constitute valid and legally binding
           obligations of the Company enforceable against the Company 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; and the Shares conform to the
           description thereof contained in the Prospectus;

           (b)   This Agreement has been duly authorized, executed and delivered
           by the Company;

           In addition, subject to such counsel's customary qualifications about
     the scope of its obligations in connection with its participation in the
     preparation of documents, such counsel shall state that they have
     participated in conferences with officers and other representatives of the
     Company, representatives of Deloitte & Touche LLP, independent auditors for
     the Company, the Representative, and Counsel for the Underwriters at which
     the contents of the Prospectus and any amendment thereof or supplement
     thereto and related matters were discussed and although such counsel have
     not undertaken to investigate or verify independently, and do not assume
     any responsibility for the accuracy, completeness or fairness of the
     statements contained in the Prospectus or any amendment thereof or
     supplement thereto, and did not participate in the preparation of the
     documents incorporated by reference in the Prospectus, no facts have come
     to the attention of such counsel which would lead such counsel to believe
     that at the date of this Agreement, the Prospectus (other than the
     historical, proforma, projected or other financial statements, information
     and data and statistical information and data included or incorporated by
     reference therein, in each case as to which no opinion need be given)
     contained any untrue statement of a material fact or omitted to state any
     material fact

                                     Page 7
<PAGE>
 
     necessary to make the statements therein, in the light of the circumstances
     under which they were made, not misleading, or that the Prospectus at the
     applicable Closing Date (other than the historical, proforma, projected or
     other financial statements, information and data and statistical
     information and data included or incorporated by reference therein, in each
     case as to which no opinion need be given) includes any untrue statement of
     a material fact or omits to state a material fact necessary in order to
     make the statements therein, in the light of the circumstances under which
     they were made, not misleading.

          In rendering such opinion, McGuire, Woods, Battle & Boothe, L.L.P. may
     rely (A) as to matters governed by New York law upon the opinion of Counsel
     for the Underwriters, referred to below and (B) as to matters of fact, to
     the extent they deem proper, on certificates of responsible officers of the
     Company and public officials. Except as otherwise set forth herein, all
     references in this Section 5.5 to the Prospectus shall be deemed to include
     any amendment or supplement thereto at the applicable Closing Date.

          The opinion of McGuire, Woods, Battle & Boothe, L.L.P. shall be
     rendered to the Representative at the request of the Company and shall so
     state therein.

          5.6  The Representative shall have received from [Underwriters'
     Counsel], counsel for the Underwriters, such opinion or opinions, dated the
     Closing Date, with respect to the validity of the Shares, the Registration
     Statement, the Prospectus, this Agreement and other related matters as the
     Representative may reasonably request, and the Company shall have furnished
     to such counsel such documents as they reasonably request for the purpose
     of enabling them to pass upon such matters. In rendering such
     opinion,[Underwriters' Counsel] may rely as to matters governed by Virginia
     law upon the opinion of Thomas F. Farrell Esq. or such other counsel
     referred to in paragraph 5.4 above.

          5.7  On the Closing Date, the Representative shall have received from

     satisfactory to the Representative.

request with respect to the good standing of the Company, the due authorization
and issuance of the Additional Shares and other matters related to the issuance
of the Additional Shares.

                                   Section VI

the Registration Statement shall be in effect or proceeding therefor shall have
been instituted or, to the knowledge of the Company, shall be contemplated.

     If the foregoing condition shall not have been satisfied, then the Company
shall be entitled, by notice in writing or by telegram to the Representative, to
terminate this Agreement without any liability on the part of the Company or any
Underwriter, except as provided in paragraph 7.4 hereof.

                                  Section VII

     In further consideration of the agreements of the Underwriters herein
contained, the Company covenants as follows:

           7.1  Promptly to deliver to the Representative conformed copies of
     the Registration Statement (including all documents incorporated by
     reference therein) as originally filed and of all amendments thereto
     heretofore or hereafter filed, including conformed copies of all exhibits
     except those incorporated by reference, and such number of copies of the
     Registration Statement (but excluding the exhibits), each related
     preliminary prospectus, the Prospectus, and any amendments and supplements
     thereto, as the Representative may reasonably request;

           7.2  If, at any time when a prospectus relating to the Shares is
     required to be delivered under the Securities Act in connection with sales
     by an Underwriter or dealer, any event occurs as a result of which the
     Prospectus as then amended or supplemented would include an untrue
     statement of a material fact or omit to state any material fact necessary
     to make the statements therein, in the light of the circumstances under
     which they were made, not misleading, or if it is necessary at any time to
     amend the Prospectus to comply with the Securities Act in connection with
     sales by an Underwriter or dealer, to advise the Representative of such
     event or necessity, as the case may be, and, promptly upon request made by
     the Representative, to prepare and file with the Commission an amendment or
     supplement which will correct such statement or omission or an amendment
     which will effect such compliance; provided that the expense of preparing
     and filing and such amendment or supplement (i) which is necessary in
     connection with such a delivery of a prospectus more than nine months after
     the date of this Agreement or (ii) which relates solely to the activities
     of any Underwriter shall be borne by the Underwriter or Underwriters or the
     dealer or dealers requiring the same; and provided further that the
     Representative shall, upon inquiry by the Company, advise the Company
     whether or not any Underwriter or dealer which shall have been selected by
     the Representative retains any unsold Shares and, for the purposes of this
     paragraph 7.3, the Company shall be entitled to assume that the
     distribution of the Shares has been completed when it is advised by the
     Representative that no Underwriter or such dealer retains any Shares;

                                     Page 9
<PAGE>
 
          7.3  As soon as practicable, to make generally available to its
     security holders an earnings statement covering a period of at least twelve
     months beginning after the "effective date of the registration statement"
     within the meaning of Rule 158 under the Act which will satisfy the
     provisions of Section 11(a) of the Act;

          7.4  To pay or bear (i) all expenses in connection with the matters
     herein required to be performed by it, including all expenses (except as
     provided in paragraph 7.2 above) in connection with the preparation and
     filing of the Registration Statement and the Prospectus, and any amendment
     or supplement thereto, and the furnishing of copies thereof to the
     Underwriters, and all audits, statements or reports in connection
     therewith, and all expenses in connection with the original issue and
     delivery of the Shares to the Underwriters at the place designated in
     Section IV hereof, and all Federal and State taxes (if any) payable (not
     including any transfer taxes) upon the original issue of the Shares, (ii)
     all expenses in connection with the printing of this Agreement; and

          7.5  Before amending or supplementing the Registration Statement or
     the Prospectus (to the extent that such amendment or supplement relates to
     the Shares), to furnish to the Representative a copy of each such proposed
     amendment or supplement.

                                  Section VIII

     The Company agrees to indemnify and hold harmless each Underwriter and each
person, if any, who controls such Underwriter within the meaning of either
Section 15 of the Securities Act or Section 20 of the Exchange Act from and
against any and all losses, claims, damages and liabilities (including, without
limitation, any legal or other expenses reasonably incurred by any Underwriter
or any such controlling person in connection with defending or investigating any
such action or claim) caused by any untrue statement or alleged untrue statement
of a material fact contained in the Registration Statement or any amendment
thereof, any preliminary prospectus or the Prospectus (as amended or
supplemented if the Company shall have furnished any amendments or supplements
thereto), or caused by any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, except insofar as such losses, claims, damages or
liabilities are caused by any such untrue statement or omission or alleged
untrue statement or omission based upon information relating to any Underwriter
furnished to the Company in writing by such Underwriter through the
Representative expressly for use therein.

     Each Underwriter agrees, severally and not jointly, to indemnify and hold
harmless the Company, its directors, its officers who sign the Registration
Statement and each person, if any, who controls the Company within the meaning
of either Section 15 of the Securities Act or Section 20 of the Exchange Act to
the same extent as the foregoing indemnity from the Company to such Underwriter,
but only with reference to information relating to such Underwriter furnished to
the Company by such Underwriter through the Representative expressly for use in
the Registration Statement, any preliminary prospectus, the Prospectus or any
amendments or supplements thereto.

                                    Page 10
<PAGE>
 
     In case any proceeding (including any governmental investigation) shall be
instituted involving any person in respect of which indemnity may be sought
pursuant to either of the two preceding paragraphs, such person (the
"indemnified party") shall promptly notify the person against whom such
indemnity may be sought (the "indemnifying party") in writing and the
indemnifying party, upon request of the indemnified party, shall retain counsel
reasonably satisfactory to the indemnified party to represent the indemnified
party and any others the indemnifying party may designate in such proceeding and
shall pay the fees and disbursements of such counsel related to such proceeding.
In any such proceeding, any indemnified party shall have the right to retain its
own counsel, but the fees and expenses of such counsel shall be at the expense
of such indemnified party unless (i) the indemnifying party and the indemnified
party shall have mutually agreed to the retention of such counsel or (iii) the
named parties to any such proceeding (including any impleaded parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them. It is understood that the indemnifying party
shall not, in respect of the legal expenses of any indemnified party in
connection with any proceeding or related proceedings in the same jurisdiction,
be liable for the fees and expenses of more than one separate firm (in addition
to any local counsel) for all such indemnified parties and that all such fees
and expenses shall be reimbursed as they are incurred. Such firm shall be
designated in writing by the Representative, in the case of parties indemnified
pursuant to the second preceding paragraph, and by the Company, in the case of
parties indemnified pursuant to the first preceding paragraph. The indemnifying
party shall not be liable for any settlement of any proceeding effected without
its written consent, but if settled with such consent or if there be a final
judgment for the plaintiff, the indemnifying party agrees to indemnify the
indemnified party from and against any loss or liability by reason of such
settlement or judgment. Notwithstanding the foregoing sentence, if at any time
an indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel as contemplated by the second
and third sentences of this paragraph, the indemnifying party agrees that it
shall be liable for any settlement, of any proceeding effected without its
written consent if (i) such settlement is entered into more than 30 days after
receipt by such indemnifying party of the aforesaid request and (ii) such
indemnifying party shall not have reimbursed the indemnified party in accordance
with such request prior to the date of such settlement. No indemnifying party
shall, without the prior written consent of the indemnified party, effect any
settlement of any pending or threatened proceeding in respect of which any
indemnified party is or could have been a party and indemnity would have been
sought hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all liability on claims
that are the subject matter of such proceeding.

     If any Underwriter or person shall be entitled to indemnification by the
terms of this Section VIII, and if such claim for indemnification is thereafter
held by a court to be unavailable for any reason other than by reason of the
terms of this Section VIII or if such claim is unavailable under controlling
precedent, such Underwriter or person shall be entitled to contribution from the
Company to liabilities and expenses, except to the extent that contribution is
not permitted under Section 11(f) of the Securities Act. In determining the
amount of contribution to which such Underwriter or person is entitled, there
shall be considered the

                                    Page 11
<PAGE>
 
relative benefits received by such Underwriter or person and the Company from
the offering of the Shares (taking into account the portion of the proceeds of
the offering realized by each), the Underwriter's or person's relative knowledge
and access to information concerning the matter with respect to which the claim
was asserted, the opportunity to correct and prevent any statement or omission,
and any other statement or omission, and any other equitable considerations
appropriate under the circumstances.  The Company and the Underwriters agree
that it would not be equitable if the amount of such contribution were
determined by pro rata or per capita allocation (even if the Underwriters were
treated as one entity for such purpose).

     The indemnity and contribution provisions contained in this Section VIII
and the representations and warranties of the Company contained in this
Agreement shall remain operative and in full force and effect regardless of (i)
any termination of this Agreement, (ii) any investigation made by or on behalf
of any Underwriter or any person controlling any Underwriter or by or on behalf
of the Company, its officers or directors or any person controlling the Company
and (iii) acceptance of and payment for any of the Shares.

                                   Section IX

     This Agreement shall be subject to termination by notice given by the
Representative to the Company, if (a) after the execution and delivery of this
Agreement and prior to the Closing Date (i) trading generally shall have been
suspended or materially limited on or by the New York Stock Exchange or the
Nasdaq Stock Market, (ii) trading of any securities of the Company shall have
been suspended on any exchange or in any over-the-counter market, (iii) a
general moratorium on commercial banking activities in New York shall have been
declared by either Federal or New York State authorities or (iv) there shall
have occurred any outbreak or escalation of hostilities or any change in
financial markets or any calamity or crisis that, in the Representative's
reasonable judgment, is material and adverse and (b) in the case of any of the
events specified in clauses (a) (i) through (iv), such event singly or together
with any other such event makes it, in the Representative's reasonable judgment,
impracticable to market the Shares on the terms and in the manner contemplated
in the Prospectus.

                                   Section X

     This Agreement shall become effective upon the later of (x) execution and
delivery hereof by the parties hereto or (y) release of notification of the
effectiveness of the Registration Statement by the Commission.

     If, on the Closing Date or the Option Closing Date, as the case may be, any
one or more of the Underwriters shall fail or refuse to purchase Shares that it
or they have agreed to purchase hereunder on such date, and the aggregate number
of Shares which such defaulting Underwriter or Underwriters agreed but failed or
refused to purchase is not more than one-tenth of the aggregate number of the
Shares to be purchased on such date, the other Underwriters shall be obligated
severally in the proportions that the number of Firm Shares set forth opposite
their respective names in Schedule I bears to the aggregate number of Firm
Shares set forth opposite

                                    Page 12
<PAGE>
 
the names of all such non-defaulting Underwriters, or in such other proportions
as the Representative may specify, to purchase the Shares which such defaulting
Underwriter or Underwriters agreed but failed or refused to purchase on such
date; provided that in no event shall the number of Shares that any Underwriter
has agreed to purchase pursuant to Section II be increased pursuant to this
Section X by an amount in excess of [one-ninth] of such number of Shares without
the written consent of such Underwriter.  If, on the Closing Date or the Option
Closing Date, as the case may be, any Underwriter or Underwriters shall fail or
refuse to purchase Shares and the aggregate number of Shares with respect to
which such default occurs is more than one-tenth of the aggregate number of
Shares to be purchased on such date, and arrangements satisfactory to the
Company for the purchase of such Shares are not made within [36] hours after
such default, this Agreement shall terminate without liability on the part of
any non-defaulting Underwriter or the Company. In any such case either the
Representative or the Company shall have the right to postpone the Closing Date
or the Option Closing Date, as the case may be, but in no event for longer than
[seven] days, in order that the required changes, if any, in the Registration
Statement and in the Prospectus or in any other documents or arrangements may be
effected.  Any action taken under this paragraph shall not relieve any
defaulting Underwriter from liability in respect of any default of such
Underwriter under this Agreement.

     If this Agreement shall be terminated by the Underwriters, or any of them,
because of any failure or refusal on the part of the Company to comply with the
terms or to fulfill any of the conditions of this Agreement, or if for any
reason the Company shall be unable to perform its obligations under this
Agreement, the Company will reimburse the Underwriters or such Underwriters as
have so terminated this Agreement with respect to themselves, severally, for all
out-of-pocket expenses (including the fees and disbursements of their counsel)
reasonably incurred by such Underwriters in connection with this Agreement or
the offering contemplated hereunder.

     This Agreement may be signed in two or more counterparts, each of which
shall be an original, with the same effect as if the signatures thereto and

internal laws of the State of New York.

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 an agent duly
appointed in writing. Any request, demand, authorization, direction, notice,

given or taken by Holders of Securities of such series may, alternatively, be
embodied in and evidenced by the record of Holders of Securities of such series
voting in favor thereof, either in person or by proxies duly appointed in
writing, at any meeting of Holders of Securities of such series duly called and
held in accordance with the provisions of Article Fifteen or a combination of
such instruments and any such record. Except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
or record or both are delivered to the Trustee and, where it is hereby expressly
required, to the Company. Such instrument or instruments and any such record
(and the action embodied therein and evidenced thereby) are herein sometimes
referred to as the "Act" of the Holders signing such instrument or instruments
or so voting at any such meeting. Proof of execution of any such instrument or
of a writing appointing any such agent, or of the holding by any Person of a
Security, shall be sufficient for any purpose of this Indenture and (subject to
Section 315 of the Trust Indenture Act) conclusive in favor of the Trustee and
the Company and any agent of the Trustee or the Company, if made in the manner
provided in this Section. The record of any meeting of Holders of Securities
shall be proved in the manner provided in Section 1506.

         Without limiting the generality of this Section 104, unless otherwise
provided in or pursuant to this Indenture, a Holder, including a U.S. Depository
that is a Holder of a global Security, may make, give or take, by a proxy, or
proxies, duly appointed in writing, any request, demand, authorization,
direction, notice, consent, waiver or other Act provided in or pursuant to this
Indenture or the Securities to be made, given or taken by Holders, and a U.S.
Depository that is a Holder of a global Security may provide its proxy or
proxies to the direct or indirect participants therein or the beneficial owners
of interests in any such global Security through such U.S.
Depository's standing instructions and customary practices.

         (2) The fact and date of the execution by any Person of any such
instrument or writing may be proved in any reasonable manner which the Trustee
deems sufficient and in accordance with such reasonable rules as the Trustee may
determine; and the Trustee may in any instance require further proof with
respect to any of the matters referred to in this Section.

         (3) The ownership, principal amount and serial numbers of Registered
Securities held by any Person, and the date of the commencement and the date of
the termination of holding the same, shall be proved by the Security Register.

         (4) The ownership, principal amount and serial numbers of Bearer
Securities held by any Person, and the date of the commencement and the date of
the termination of holding the same, may

                                       11
<PAGE>
 
be proved by the production of such Bearer Securities or by a certificate
executed, as depositary, by any trust company, bank, banker or other depositary
reasonably acceptable to the Company, wherever situated, if such certificate
shall be deemed by the Company and the Trustee to be satisfactory, showing that
at the date therein mentioned such Person had on deposit with such depositary,
or exhibited to it, the Bearer Securities therein described; or such facts may
be proved by the certificate or affidavit of the Person holding such Bearer
Securities, if such certificate or affidavit is deemed by the Company and the
Trustee to be satisfactory. The Trustee and the Company may assume that such
ownership of any Bearer Security continues until (1) another certificate or
affidavit bearing a later date issued in respect of the same Bearer Security is
produced, or (2) such Bearer Security is produced to the Trustee by some other
Person, or (3) such Bearer Security is surrendered in exchange for a Registered
Security, or (4) such Bearer Security is no longer Outstanding. The ownership,
principal amount and serial numbers of Bearer Securities held by the Person so
executing such instrument or writing and the date of the commencement and the
date of the termination of holding the same may also be proved in any other
manner which the Company and the Trustee deem sufficient.

         (5) If the Company shall solicit from the Holders of any Registered
Securities any request, demand, authorization, direction, notice, consent,
waiver or other Act, the Company may at its option (but is not obligated to), by
Board Resolution, fix in advance a record date for the determination of Holders
of Registered Securities entitled to give such request, demand, authorization,
direction, notice, consent, waiver or other Act. If such a record date is fixed,
such request, demand, authorization, direction, notice, consent, waiver or other
Act may be given before or after such record date, but only the Holders of
Registered Securities of record at the close of business on such record date
shall be deemed to be Holders for the purpose of determining whether Holders of
the requisite proportion of Outstanding Securities have authorized or agreed or
consented to such request, demand, authorization, direction, notice, consent,
waiver or other Act, and for that purpose the Outstanding Securities shall be
computed as of such record date; provided that no such authorization, agreement
or consent by the Holders of Registered Securities shall be deemed effective
unless it shall become effective pursuant to the provisions of this Indenture
not later than six months after the record date.

         (6) Any request, demand, authorization, direction, notice, consent,
waiver or other Act by 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 or suffered to be done by the Trustee, any Security
Registrar, any Paying Agent or the Company in reliance thereon, whether or not
notation of such Act is made upon such Security.


         Section 105.  Notices, Etc. To Trustee and Company.

<PAGE>
 
                  (1) the Trustee by any Holder or the Company shall be
         sufficient for every purpose hereunder if made, given, furnished or
         filed in writing to or with the Trustee at its Corporate Trust Office,
         Attention: Corporate Trustee Administration Department, or

                  (2) the Company by the Trustee or 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 the attention of its Treasurer 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 the Trustee by the Company.

         Section 106.  Notice to Holders of Securities; Waiver.

         Except as otherwise expressly provided in or pursuant to this
Indenture, where this Indenture provides for notice to Holders of Securities of
any event,

                  (1) such notice shall be sufficiently given to Holders of
         Registered Securities if in writing and mailed, first-class postage
         prepaid, to each Holder of a Registered Security affected by such
         event, at his address as it appears in the Security Register, not later
         than the latest date, and not earlier than the earliest date,
         prescribed for the giving of such notice; and

                  (2) such notice shall be sufficiently given to Holders of
         Bearer Securities, if any, if published in an Authorized Newspaper in
         The City of New York and, if such Securities are then listed on any
         stock exchange outside the United States, in an Authorized Newspaper in
         such city as the Company shall advise the Trustee that such stock
         exchange so requires, on a Business Day at least twice, the first such
         publication to be not earlier than the earliest date and the second
         such publication not later than the latest date prescribed for the
         giving of such notice.

         In any case where notice to Holders of Registered Securities is given
by mail, neither the failure to mail such notice, nor any defect in any notice
so mailed, to any particular Holder of a Registered Security shall affect the
sufficiency of such notice with respect to other Holders of Registered
Securities or the sufficiency of any notice to Holders of Bearer Securities
given as provided herein. Any notice which is mailed in the manner herein
provided shall be conclusively presumed to have been duly given or provided. In
the 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 the Trustee shall constitute
a sufficient notification for every purpose hereunder.

         In case by reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearer Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder. Neither failure to give notice by
publication to Holders of Bearer Securities as provided above, nor any defect in
any notice so published, shall affect the sufficiency of any notice mailed to
Holders of Registered Securities as provided above.

         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 of Securities 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.


         Section 107.  Language of Notices.

         Any request, demand, authorization, direction, notice, consent,
election or waiver required or permitted under this Indenture shall be in the
English language, except that, if the Company so elects, any published notice
may be in an official language of the country of publication.

         If any provision hereof limits, qualifies or conflicts with any duties
under any required provision of the Trust Indenture Act imposed hereon by
Section 318(c) thereof, such required provision shall control.


         Section 109.  Effect of Headings and Table of Contents.

bind its successors and assigns, whether so expressed or not.


         Section 111.  Separability Clause.

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

                  and issued by the Company in the manner and subject to any
                  conditions specified in such Opinion of Counsel, will
                  constitute legally valid and binding obligations of the
                  Company, enforceable against the Company in accordance with
                  their terms, subject to bankruptcy, insolvency,
                  reorganization, moratorium, arrangement, fraudulent
                  conveyance, fraudulent transfer or other similar laws relating
                  to or affecting creditors' rights generally, and subject to
                  general principles of equity (regardless of whether
                  enforcement is sought in a proceeding in equity or at law);
                  and

                         (c) this Indenture has been qualified under the Trust
                  Indenture Act;

                                      22
<PAGE>
 
         and

                  (2) an Officers' Certificate stating that, to the best
         knowledge of the Persons executing such certificate, no event which is,
         or after notice or lapse of time would become, an Event of Default with
         respect to any of the Securities shall have occurred and be continuing.

         If all the Securities of any series are not to be issued at one time,
it shall not be necessary to deliver an Opinion of Counsel at the time of
issuance of each Security, but such opinion shall be delivered at or before the
time of issuance of the first Security of such series. After any such first
delivery, any separate request by the Company that the Trustee authenticate
Securities of such series for original issue will be deemed to be a
certification by the Company that all conditions precedent provided for in this
Indenture relating to authentication and delivery of such Securities continue to
have been complied with.

         The Trustee shall not be required to authenticate or to cause an
Authenticating Agent to authenticate any 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 or if the Trustee,
being advised by counsel, determines that such action may not lawfully be taken.

         Each Registered Security shall be dated the date of its authentication.
Each Bearer Security and any temporary Bearer Security in global form shall be
dated as of the date specified in or pursuant to this Indenture.

         No Security or Coupon appertaining thereto 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 in Section 202 or 611 executed by or on behalf of the
Trustee or by the Authenticating Agent by the manual signature of one of its
authorized officers. Such certificate upon any Security shall be conclusive
evidence, and the only evidence, that such Security has been duly authenticated
and delivered hereunder. Except as permitted by Section 306 or 307, the Trustee
shall not authenticate and deliver any Bearer Security unless all Coupons
appertaining thereto then matured have been detached and cancelled.


         Section 304. Temporary Securities.

         Pending the preparation of definitive Securities, the Company may
execute and deliver to the Trustee and, upon Company Order, the Trustee shall
authenticate and deliver, in the manner provided in Section 303, temporary
Securities in lieu thereof 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, in registered form or, if authorized in or pursuant to this
Indenture, in bearer form with one or more Coupons or without Coupons and with
such appropriate insertions, omissions, substitutions and other variations as
the officers of the Company executing such Securities may determine, as
conclusively evidenced by their execution of such Securities. Such temporary
Securities may be in global form.

                                      23
<PAGE>
 
         Except in the case of temporary Securities in global form, which shall
be exchanged in accordance with the provisions thereof, if temporary Securities
are issued, the Company shall cause definitive Securities to be prepared without
unreasonable delay. After the preparation of definitive Securities of the same
series and containing terms and provisions that are identical to those of any
temporary Securities, such temporary Securities shall be exchangeable for such
definitive Securities upon surrender of such temporary Securities at an Office
or Agency for such Securities, without charge to any Holder thereof. Upon
surrender for cancellation of any one or more temporary Securities (accompanied
by any unmatured Coupons appertaining thereto), the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of authorized denominations of the same series
and containing identical terms and provisions; provided, however, that no
definitive Bearer Security, except as provided in or pursuant to this Indenture,
shall be delivered in exchange for a temporary Registered Security; and
provided, further, that a definitive Bearer Security shall be delivered in
exchange for a temporary Bearer Security only in compliance with the conditions
set forth in or pursuant to this Indenture. Unless otherwise provided in or
pursuant to this Indenture with respect to a temporary global Security, 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.


         Section 305. Registration, Transfer and Exchange.

         With respect to the Registered Securities of each series, if any, the
Company shall cause to be kept a register (each such register being herein
sometimes referred to as the "Security Register") at an Office or Agency for
such series in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of the Registered
Securities of such series and of transfers of the Registered Securities of such
series. Such Office or Agency shall be the "Security Registrar" for that series
of Securities. Unless otherwise specified in or pursuant to this Indenture or
the Securities, the Trustee shall be the initial Security Registrar for each
series of Securities. The Company shall have the right to remove and replace
from time to time the Security Registrar for any series of Securities; provided
that no such removal or replacement shall be effective until a successor
Security Registrar with respect to such series of Securities shall have been
appointed by the Company and shall have accepted such appointment. In the event
that the Trustee shall not be or shall cease to be Security Registrar with
respect to a series of Securities, it shall have the right to examine the
Security Register for such series at all reasonable times. There shall be only
one Security Register for each series of Securities.

         Upon surrender for registration of transfer of any Registered Security
of any series at any Office or Agency for such series, the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Registered Securities of
the same series denominated as authorized in or pursuant to this Indenture, of a
like aggregate principal amount bearing a number not contemporaneously
outstanding and containing identical terms and provisions.

         At the option of the Holder, Registered Securities of any series may be
exchanged for other Registered Securities of the same series containing
identical terms and provisions, in any authorized denominations, and of a like
aggregate principal amount, upon surrender of the Securities to be

                                      24
<PAGE>
 
exchanged at any Office or Agency for such series. Whenever any Registered
Securities are so surrendered for exchange, the Company shall execute, and the
Trustee shall authenticate and deliver, the Registered Securities which the
Holder making the exchange is entitled to receive.

         If provided in or pursuant to this Indenture, with respect to
Securities of any series, at the option of the Holder, Bearer Securities of such
series may be exchanged for Registered Securities of such series containing
identical terms, denominated as authorized in or pursuant to this Indenture and
in the same aggregate principal amount, upon surrender of the Bearer Securities
to be exchanged at any Office or Agency for such series, with all unmatured
Coupons and all matured Coupons in default thereto appertaining. If the Holder
of a Bearer Security is unable to produce any such unmatured Coupon or Coupons
or matured Coupon or Coupons in default, such exchange may be effected if the
Bearer Securities are accompanied by payment in funds acceptable to the Company
and the Trustee in an amount equal to the face amount of such missing Coupon or
Coupons, or the surrender of such missing Coupon or Coupons may be waived by the
Company and the Trustee if there is furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless. If
thereafter the Holder of such Bearer Security shall surrender to any Paying
Agent any such missing Coupon in respect of which such a payment shall have been
made, such Holder shall be entitled to receive the amount of such payment;
provided, however, that, except as otherwise provided in Section 1002, interest
represented by Coupons shall be payable only upon presentation and surrender of
those Coupons at an Office or Agency for such series located outside the United
States. Notwithstanding the foregoing, in case a Bearer Security of any series
is surrendered at any such Office or Agency for such series in exchange for a
Registered Security of such series and like tenor after the close of business at
such Office or Agency on (i) any Regular Record Date and before the opening of
business at such Office or Agency on the relevant Interest Payment Date, or (ii)
any Special Record Date and before the opening of business at such Office or
Agency on the related date for payment of Defaulted Interest, such Bearer
Security shall be surrendered without the Coupon relating to such Interest
Payment Date or proposed date of payment, as the case may be (or, if such Coupon
is so surrendered with such Bearer Security, such Coupon shall be returned to
the Person so surrendering the Bearer Security), and interest or Defaulted
Interest, as the case may be, shall not be payable on such Interest Payment Date
or proposed date for payment, as the case may be, in respect of the Registered
Security issued in exchange for such Bearer Security, but shall be payable only
to the Holder of such Coupon when due in accordance with the provisions of this
Indenture.

         If provided in or pursuant to this Indenture with respect to Securities
of any series, at the option of the Holder, Registered Securities of such series
may be exchanged for Bearer Securities upon such terms and conditions as may be
provided in or pursuant to this Indenture with respect to such series.

         Whenever any Securities are surrendered for exchange as contemplated by
the immediately preceding two paragraphs, the Company shall execute, and the
Trustee shall authenticate and deliver, the Securities which the Holder making
the exchange is entitled to receive.

         Notwithstanding the foregoing, except as otherwise provided in or
pursuant to this Indenture, any global Security shall be exchangeable for
definitive Securities only if (i) the Depository is at any time unwilling,
unable or ineligible to continue as Depository and a successor depository is not

                                      25
<PAGE>
 
appointed by the Company within 90 days of the date the Company is so informed
in writing, (ii) the Company executes and delivers to the Trustee a Company
Order to the effect that such global Security shall be so exchangeable, or (iii)
an Event of Default has occurred and is continuing with respect to the
Securities. If the beneficial owners of interests in a global Security are
entitled to exchange such interests for definitive Securities as the result of
an event described in clause (i), (ii) or (iii) of the preceding sentence, then
without unnecessary delay but in any event not later than the earliest date on
which such interests may be so exchanged, the Company shall deliver to the
Trustee definitive Securities in such form and denominations as are required by
or pursuant to this Indenture, and of the same series, containing identical
terms and in aggregate principal amount equal to the principal amount of such
global Security, executed by the Company. On or after the earliest date on which
such interests may be so exchanged, such global Security shall be surrendered
from time to time by the U.S. Depository or such other Depository as shall be
specified in the Company Order with respect thereto, and in accordance with
instructions given to the Trustee and the U.S. Depository or such other
Depository, as the case may be (which instructions shall be in writing but need
not be contained in or accompanied by an Officers' Certificate or be accompanied
by an Opinion of Counsel), as shall be specified in the Company Order with
respect thereto to the Trustee, as the Company's agent for such purpose, to be
exchanged, in whole or in part, for definitive Securities as described above
without charge. The Trustee shall authenticate and make available for delivery,
in exchange for each portion of such surrendered global Security, a like
aggregate principal amount of definitive Securities of the same series of
authorized denominations and of like tenor as the portion of such global
Security to be exchanged, which (unless such Securities are not issuable both as
Bearer Securities and as Registered Securities, in which case the definitive
Securities exchanged for the global Security shall be issuable only in the form
in which the Securities are issuable, as provided in or pursuant to this
Indenture) shall be in the form of Bearer Securities or Registered Securities,
or any combination thereof, as shall be specified by the beneficial owner
thereof, but subject to the satisfaction of any certification or other
requirements to the issuance of Bearer Securities; provided, however, that no
such exchanges may occur during a period beginning at the opening of business 15
days before any selection of Securities of the same series to be redeemed and
ending on the relevant Redemption Date; and provided, further, that (unless
otherwise provided in or pursuant to this Indenture) no Bearer Security
delivered in exchange for a portion of a global Security shall be mailed or
otherwise delivered to any location in the United States. Promptly following any
such exchange in part, such global Security shall be returned by the Trustee to
such Depository or the U.S. Depository, as the case may be, or such other
Depository or U.S. Depository referred to above in accordance with the
instructions of the Company referred to above. If a Registered Security is
issued in exchange for any portion of a global Security after the close of
business at the Office or Agency for such Security where such exchange occurs on
or after (i) any Regular Record Date for such Security and before the opening of
business at such Office or Agency on the next Interest Payment Date, or (ii) any
Special Record Date for such Security and before the opening of business at such
Office or Agency on the related proposed date for payment of interest or
Defaulted Interest, as the case may be, interest shall not be payable on such
Interest Payment Date or proposed date for payment, as the case may be, in
respect of such Registered Security, but shall be payable on such Interest
Payment Date or proposed date for payment, as the case may be, only to the
Person to whom interest in respect of such portion of such global Security shall
be payable in accordance with the provisions of this Indenture.

                                      26
<PAGE>
 
         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 entitling the Holders thereof to the same benefits under this Indenture
as the Securities surrendered upon such registration of transfer or exchange.

         Every Registered Security presented or surrendered for registration of
transfer or for exchange or redemption shall (if so required by the Company or
the Security Registrar for such Security) be duly endorsed, or be accompanied by
a written instrument of transfer in form satisfactory to the Company and the
Security Registrar for such Security 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, or redemption of Securities, but the Company may require payment of a
sum sufficient to cover any tax or other governmental charge and any other
expenses (including fees and expenses of the Trustee) that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 304, 905 or 1107, upon repayment in part of
any Registered Security pursuant to Article Thirteen, or upon surrender in part
of any Registered Security for conversion or exchange into Common Stock or other
securities pursuant to its terms, in each case not involving any transfer.

         Except as otherwise provided in or pursuant to this Indenture, the
Company shall not be required (i) to issue, register the transfer of or exchange
any Securities during a period beginning at the opening of business 15 days
before the day of the selection for redemption of Securities of like tenor and
the same series under Section 1103 and ending at the close of business on the
day of such selection, or (ii) to register the transfer of or exchange any
Registered Security so selected for redemption in whole or in part, except in
the case of any Security to be redeemed in part, the portion thereof not to be
redeemed, or (iii) to exchange any Bearer Security so selected for redemption
except, to the extent provided with respect to such Bearer Security, that such
Bearer Security may be exchanged for a Registered Security of like tenor and the
same series, provided that such Registered Security shall be immediately
surrendered for redemption with written instruction for payment consistent with
the provisions of this Indenture or (iv) to issue, register the transfer of or
exchange any Security which, in accordance with its terms, has been surrendered
for repayment at the option of the Holder, except the portion, if any, of such
Security not to be so repaid.


         Section 306. Mutilated, Destroyed, Lost and Stolen Securities.

         If any mutilated Security or a Security with a mutilated Coupon
appertaining to it is surrendered to the Trustee, subject to the provisions of
this Section 306, the Company shall execute and the Trustee shall authenticate
and deliver in exchange therefor a new Security of the same series containing
identical terms and of like principal amount and bearing a number not
contemporaneously outstanding, with Coupons appertaining thereto corresponding
to the Coupons, if any, appertaining to the surrendered Security.

         If there be delivered to the Company and to the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security or Coupon,
and (ii) such security or indemnity as may

                                      27
<PAGE>
 
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 or Coupon has been acquired by a bona fide purchaser, the Company shall
execute and, upon the Company's request the Trustee shall authenticate and
deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or
stolen Security or in exchange for the Security to which a destroyed, lost or
stolen Coupon appertains with all appurtenant Coupons not destroyed, lost or
stolen, a new Security of the same series containing identical terms and of like
principal amount and bearing a number not contemporaneously outstanding, with
Coupons corresponding to the Coupons, if any, appertaining to such destroyed,
lost or stolen Security or to the Security to which such destroyed, lost or
stolen Coupon appertains.

         Notwithstanding the foregoing provisions of this Section 306, in case
any mutilated, destroyed, lost or stolen Security or Coupon 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 or Coupon; provided, however, that
payment of principal of, any premium or interest on or any Additional Amounts
with respect to any Bearer Securities shall, except as otherwise provided in
Section 1002, be payable only at an Office or Agency for such Securities located
outside the United States and, unless otherwise provided in or pursuant to this
Indenture (including this paragraph), any interest on Bearer Securities and any
Additional Amounts with respect to such interest shall be payable only upon
presentation and surrender of the Coupons appertaining thereto.

         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, with any Coupons appertaining thereto issued
pursuant to this Section in lieu of any destroyed, lost or stolen Security, or
in exchange for a Security to which a destroyed, lost or stolen Coupon
appertains shall constitute a separate obligation of the Company, whether or not
the destroyed, lost or stolen Security and Coupons appertaining thereto or the
destroyed, lost or stolen Coupon 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 such series and any
Coupons, if any, duly issued hereunder.

         The provisions of this Section, as amended or supplemented pursuant to
this Indenture with respect to particular Securities or generally, shall be
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 or Coupons.


         Section 307. Payment of Interest and Certain Additional Amounts; Rights
                      to Interest and Certain Additional Amounts Preserved.

         Unless otherwise provided in or pursuant to this Indenture, any
interest on and any Additional Amounts with respect to any Registered Security
which shall be payable, and are punctually paid or duly provided for, on any
Interest Payment Date shall be paid to the Person in

                                      28
<PAGE>
 
whose name such Security (or one or more Predecessor Securities) is registered
as of the close of business on the Regular Record Date for such interest. Unless
otherwise provided in or pursuant to this Indenture, in case a Bearer Security
is surrendered in exchange for a Registered Security after the close of business
at an Office or Agency for such Security on any Regular Record Date therefor and
before the opening of business at such Office or Agency on the next succeeding
Interest Payment Date therefor, such Bearer Security shall be surrendered
without the Coupon relating to such Interest Payment Date and interest shall not
be payable on such Interest Payment Date in respect of the Registered Security
issued in exchange for such Bearer Security, but shall be payable only to the
Holder of such Coupon when due in accordance with the provisions of this
Indenture.

          Unless otherwise provided in or pursuant to this Indenture, any
interest on and any Additional Amounts with respect to any Registered Security
which shall be payable, but shall not be punctually paid or duly provided for,
on any Interest Payment Date for such Registered Security (herein called
"Defaulted Interest") shall forthwith cease to be payable to the Holder thereof
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 Person in whose name such Registered Security (or a
         Predecessor Security thereof) shall be 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 such Registered Security 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 on or prior
         to the date of the proposed payment, such money when so deposited to be
         held in trust for the benefit of the Person 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 the
         Holder of such Registered Security (or a Predecessor Security thereof)
         at his address as it appears in the Security Register not less than 10
         days prior to such Special Record Date. The Trustee may, in its
         discretion, in the name and at the expense of the Company cause a
         similar notice to be published at least once in an Authorized Newspaper
         of general circulation in the Borough of Manhattan, The City of New
         York, but such publication shall not be a condition precedent to the
         establishment of such Special Record Date. Notice of the proposed
         payment of such Defaulted Interest and the Special Record Date therefor
         having been mailed as aforesaid, such Defaulted Interest shall be paid
         to the Person in whose name such Registered Security (or a Predecessor
         Security thereof) shall be registered at the close of business on such
         Special Record Date and shall no longer be payable pursuant to the
         following clause (2). In case a Bearer Security is surrendered at the
         Office or Agency for such Security in exchange for a Registered
         Security after the close of business at such

                                      29
<PAGE>
 
         Office or Agency on any Special Record Date and before the opening of
         business at such Office or Agency on the related proposed date for
         payment of Defaulted Interest, such Bearer Security shall be
         surrendered without the Coupon relating to such Defaulted Interest and
         Defaulted Interest shall not be payable on such proposed date of
         payment in respect of the Registered Security issued in exchange for
         such Bearer Security, but shall be payable only to the Holder of such
         Coupon when due in accordance with the provisions of this Indenture.

                  (2) The Company may make payment of any Defaulted Interest in
         any other lawful manner not inconsistent with the requirements of any
         securities exchange on which such Security 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 payment shall be deemed practicable by the Trustee.

         Unless otherwise provided in or pursuant to this Indenture or the
Securities of any particular series, at the option of the Company, interest on
Registered Securities that bear interest may be paid by mailing a check to the
address of the Person entitled thereto as such address shall appear in the
Security Register or by transfer to an account maintained by the payee with a
bank located in the United States, provided that appropriate wire transfer
instructions shall have been delivered by such payee to the Paying Agent at
least five Business Days prior to the applicable date for payment of interest.

         Subject to the foregoing provisions of this Section and Section 305,
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 Registered 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 Registered Security is registered in the
Security Register as the owner of such Registered Security for the purpose of
receiving payment of principal of, any premium and (subject to Sections 305 and
307) interest on and any Additional Amounts with respect to such Registered
Security and for all other purposes whatsoever, whether or not any payment with
respect to such Registered Security shall be overdue, and neither the Company,
the Trustee or any agent of the Company or the Trustee shall be affected by
notice to the contrary.

         The Company, the Trustee and any agent of the Company or the Trustee
may treat the bearer of any Bearer Security or the bearer of any Coupon as the
absolute owner of such Security or Coupon for the purpose of receiving payment
thereof or on account thereof and for all other purposes whatsoever, whether or
not any payment with respect to such Security or Coupon shall be overdue, and
neither the Company, the Trustee or any agent of the Company or the Trustee
shall be affected by notice to the contrary.

                                      30
<PAGE>
 
         No holder of any beneficial interest in any global Security held on its
behalf by a U.S. Depository or Depository shall have any rights under this
Indenture with respect to such global Security, and such U.S. Depository or
Depository may be treated by the Company, the Trustee, and any agent of the
Company or the Trustee as the owner of such global Security for all purposes
whatsoever. None of the Company, the Trustee, any Paying Agent or the Security
Registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of a global Security or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.


         Section 309. Cancellation.

         All Securities and Coupons surrendered for payment, redemption,
registration of transfer, exchange or conversion or for credit against any
sinking fund payment shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee, and any such Securities and Coupons, as well as
Securities and Coupons surrendered directly to the Trustee for any such purpose,
shall be cancelled promptly by the Trustee. 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 all Securities so delivered shall be cancelled promptly 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 or pursuant to this Indenture. All cancelled Securities and Coupons held by
the Trustee shall be disposed of by the Trustee in accordance with its customary
procedures, unless by a Company Order the Company directs their return to it.


         Section 310. Computation of Interest.

         Except as otherwise provided in or pursuant to this Indenture or in the
Securities of any series, interest on the Securities shall be computed on the
basis of a 360-day year of twelve 30-day months.


         Section 311. CUSIP, CINS or ISIN Numbers.

         The Company in issuing the Securities may use "CUSIP", "CINS" or "ISIN"
numbers (if then generally in use), and, if so, the Trustee or the Company shall
use "CUSIP", "CINS" or "ISIN" numbers in notices of redemption or repurchase 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 or repurchase
and that reliance may be placed only on the other identification numbers printed
on the Securities, and any such redemption or repurchase shall not be affected
by any defect in or omission of such numbers.

         Section 401. Satisfaction and Discharge.

         Upon the direction of the Company by a Company Order, this Indenture
shall cease to be of further effect with respect to any series of Securities
specified in such Company Order and any Coupons appertaining thereto, and the
Trustee, on receipt of a Company Order, at the expense of the Company, shall
execute proper instruments acknowledging satisfaction and discharge of this
Indenture as to such series, when


         (1)      either

                          (a) all Securities of such series theretofore
                  authenticated and delivered and all Coupons appertaining
                  thereto (other than (i) Coupons appertaining to Bearer
                  Securities of such series surrendered in exchange for
                  Registered Securities of such series and maturing after such
                  exchange whose surrender is not required or has been waived as
                  provided in Section 305, (ii) Securities and Coupons of such
                  series which have been destroyed, lost or stolen and which
                  have been replaced or paid as provided in Section 306, (iii)
                  Coupons appertaining to Securities of such series called for
                  redemption and maturing after the relevant Redemption Date
                  whose surrender has been waived as provided in Section 1106,
                  and (iv) Securities and Coupons of such series 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 of such series and, in the
                  case of (i) or (ii) below, any Coupons appertaining thereto
                  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)   if redeemable at the option of the
                          Company, 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 (i), (ii) or (iii) above, has
                  deposited or caused to be deposited with the Trustee as trust
                  funds in trust for such purpose, money in the Currency in
                  which such Securities are payable in an amount sufficient to
                  pay and

                                      32
<PAGE>
 
                  discharge the entire indebtedness on such Securities and any
                  Coupons appertaining thereto not theretofore delivered to the
                  Trustee for cancellation, including the principal of, any
                  premium and interest on, and, to the extent that the
                  Securities of such series provide for the payment of
                  Additional Amounts thereon and the amount of any such
                  Additional Amounts is at the time of deposit reasonably
                  determinable by the Company (in the exercise by the Company of
                  its sole and absolute discretion), any Additional Amounts with
                  respect to, such Securities and any Coupons appertaining
                  thereto, to the date of such deposit (in the case of
                  Securities which have become due and payable) or to the
                  Maturity thereof, as the case may be;

                  (2) the Company has paid or caused to be paid all other sums
         payable hereunder by the Company with respect to the Outstanding
         Securities of such series and any Coupons appertaining thereto; 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 as to such series have been complied with.

         In the event there are Securities of two or more series hereunder, the
Trustee shall be required to execute an instrument acknowledging satisfaction
and discharge of this Indenture only if requested to do so with respect to
Securities of such series as to which it is Trustee and if the other conditions
thereto are met.

         Notwithstanding the satisfaction and discharge of this Indenture with
respect to any series of Securities, the obligations of the Company to the
Trustee under Section 606 and, if money shall have been deposited with the
Trustee pursuant to subclause (b) of clause (1) of this Section, the obligations
of the Company and the Trustee with respect to the Securities of such series
under Sections 305, 306, 403, 1002 and 1003, with respect to the payment of
Additional Amounts, if any, with respect to such Securities as contemplated by
Section 1004 (but only to the extent that the Additional Amounts payable with
respect to such Securities exceed the amount deposited in respect of such
Additional Amounts pursuant to Section 401(1)(b)), and with respect to any
rights to convert or exchange such Securities into Common Stock or other
securities, shall survive.


         Section 402. Defeasance and Covenant Defeasance.

         (1) Unless, pursuant to Section 301, either or both of (i) defeasance
of the Securities of or within a series under clause (2) of this Section 402 or
(ii) covenant defeasance of the Securities of or within a series under clause
(3) of this Section 402 shall not be applicable with respect to the Securities
of such series, then such provisions, together with the other provisions of this
Section 402 (with such modifications thereto as may be specified pursuant to
Section 301 with respect to any Securities), shall be applicable to such
Securities and any Coupons appertaining thereto, and the

                                      33
<PAGE>
 
Company may at its option by Board Resolution, at any time, with respect to such
Securities and any Coupons appertaining thereto, elect to have Section 402(2) or
Section 402(3) be applied to such Outstanding Securities and any Coupons
appertaining thereto upon compliance with the conditions set forth below in this
Section 402.

         (2) Upon the Company's exercise of the above option applicable to this
Section 402(2) with respect to any Securities of or within a series, the Company
shall be deemed to have been discharged from its obligations with respect to
such Outstanding Securities and any Coupons appertaining thereto on the date the
conditions set forth in clause (4) of this Section 402 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 such Outstanding Securities and any Coupons appertaining thereto,
which shall thereafter be deemed to be "Outstanding" only for the purposes of
clause (5) of this Section 402 and the other Sections of this Indenture referred
to in clauses (i) and (ii) below, and to have satisfied all of its other
obligations under such Securities and any Coupons appertaining thereto and this
Indenture insofar as such Securities and any Coupons appertaining thereto 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: (i) the rights of
Holders of such Outstanding Securities and any Coupons appertaining thereto to
receive, solely from the trust fund described in clause (4) of this Section 402
and as more fully set forth in such Section, payments in respect of the
principal of (and premium, if any) and interest, if any, on, and Additional
Amounts, if any, with respect to, such Securities and any Coupons appertaining
thereto when such payments are due, and any rights of such Holder to convert or
exchange such Securities into Common Stock or other securities, (ii) the
obligations of the Company and the Trustee with respect to such Securities under
Sections 305, 306, 1002 and 1003, with respect to the payment of Additional
Amounts, if any, on such Securities as contemplated by Section 1004 (but only to
the extent that the Additional Amounts payable with respect to such Securities
exceed the amount deposited in respect of such Additional Amounts pursuant to
Section 401(4)(a) below), and with respect to any rights to convert or exchange
such Securities into Common Stock or other securities, (iii) the rights, powers,
trusts, duties and immunities of the Trustee hereunder (including under Section
606) and (iv) this Section 402. The Company may exercise its option under this
Section 402(2) notwithstanding the prior exercise of its option under clause (3)
of this Section 402 with respect to such Securities and any Coupons appertaining
thereto.

         (3) Upon the Company's exercise of the above option applicable to this
Section 402(3) with respect to any Securities of or within a series, the Company
shall be released from any covenant applicable to such Securities specified
pursuant to Section 301(19), with respect to such Outstanding Securities and any
Coupons appertaining thereto on and after the date the conditions set forth in
clause (4) of this Section 402 are satisfied (hereinafter, "covenant
defeasance"), and such Securities and any Coupons appertaining thereto shall
thereafter be deemed to be not "Outstanding" for the purposes of any direction,
waiver, consent or declaration or Act of Holders (and the consequences of any
thereof) in connection with any such covenant, but shall continue to be deemed
"Outstanding" for all other purposes hereunder. For this purpose, such covenant
defeasance means that, with respect to such Outstanding Securities and any
Coupons appertaining thereto, 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 covenant, whether directly or indirectly, by reason of any reference

                                       34
<PAGE>
 
elsewhere herein to any such covenant or by reason of reference in any such
covenant to any other provision herein or in any other document and such
omission to comply shall not constitute a default or an Event of Default under
Section 501(4) or 501(7) or otherwise, as the case may be, but, except as
specified above, the remainder of this Indenture and such Securities and Coupons
appertaining thereto shall be unaffected thereby.

         (4) The following shall be the conditions to application of clause (2)
or (3) of this Section 402 to any Outstanding Securities of or within a series
and any Coupons appertaining thereto:

                  (a) The Company shall irrevocably have deposited or caused to
         be deposited with the Trustee (or another trustee satisfying the
         requirements of Section 607 who shall agree to comply with the
         provisions of this Section 402 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 and any Coupons appertaining thereto, (1) an
         amount in Dollars or in such Foreign Currency in which such Securities
         and any Coupons appertaining thereto are then specified as payable at
         Stated Maturity, or (2) Government Obligations applicable to such
         Securities and Coupons appertaining thereto (determined on the basis of
         the Currency in which such Securities and Coupons appertaining thereto
         are then specified as payable at Stated Maturity) 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 of principal of (and premium, if any) and
         interest, if any, on such Securities and any Coupons appertaining
         thereto, money in an amount, or (3) a combination thereof, in any case,
         in an amount, sufficient, without consideration of any reinvestment of
         such principal and interest, 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, (y) the principal of (and premium, if any) and
         interest, if any, on, and, to the extent that such Securities provide
         for the payment of Additional Amounts thereon and the amount of any
         such Additional Amounts is at the time of deposit reasonably
         determinable by the Company (in the exercise by the Company of its sole
         and absolute discretion), any Additional Amounts with respect to, such
         Outstanding Securities and any Coupons appertaining thereto to and
         including the Stated Maturity of such principal or installment of
         principal or interest or the Redemption Date established pursuant to
         clause (e) below and (z) any mandatory sinking fund payments or
         analogous payments applicable to such Outstanding Securities and any
         Coupons appertaining thereto on the day on which such payments are due
         and payable in accordance with the terms of this Indenture and of such
         Securities and any Coupons appertaining thereto.

                  (b) Such defeasance or covenant defeasance shall not result in
         a breach or violation of, or constitute a default under, this Indenture
         or any other material agreement or instrument to which the Company is a
         party or by which it is bound.

                  (c) Solely in the case of an election under clause (2) of this
         Section 402, no Event of Default or event which with notice or lapse of
         time or both would become an Event of Default with respect to such
         Securities and any Coupons appertaining thereto shall have

                                       35
<PAGE>
 
         occurred and be continuing on the date of such deposit and, with
         respect to defeasance only, at any time during the period ending on the
         91st day after the date of such deposit (it being understood that this
         condition shall not be deemed satisfied until the expiration of such
         period).

                  (d) In the case of an election under clause (2) of this
         Section 402, the Company shall have delivered to the Trustee an Opinion
         of Counsel stating that (i) the Company has received from the Internal
         Revenue Service a letter ruling, or there has been published by the
         Internal Revenue Service a Revenue Ruling, or (ii) since the date of
         execution of this Indenture, there has been a change in the applicable
         Federal income tax law, in either case to the effect that, and based
         thereon such opinion shall confirm that, the Holders of such
         Outstanding Securities and any Coupons appertaining thereto 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.

                  (e) In the case of an election under clause (3) of this
         Section 402, the Company shall have delivered to the Trustee an Opinion
         of Counsel to the effect that the Holders of such Outstanding
         Securities and any Coupons appertaining thereto 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.

                  (f) If the Securities are to be redeemed prior to Stated
         Maturity (other than from mandatory sinking fund payments or analogous
         payments), notice of such redemption shall have been duly given
         pursuant to this Indenture or provision therefor satisfactory to the
         Trustee shall have been made.

                  (g) The Company shall have delivered to the Trustee an
         Officers' Certificate and an Opinion of Counsel, each stating that all
         conditions precedent to the defeasance or covenant defeasance under
         clause (2) or (3) of this Section 402 (as the case may be) have been
         complied with.

                  (h) Notwithstanding any other provisions of this Section
         402(4), such defeasance or covenant defeasance shall be effected in
         compliance with any additional or substitute terms, conditions or
         limitations which may be imposed on the Company in connection therewith
         pursuant to Section 301.

         (5) Subject to the provisions of the last paragraph of Section 1003,
all money and Government Obligations (or other property as may be provided
pursuant to Section 301) (including the proceeds thereof) deposited with the
Trustee (or other qualifying trustee, collectively for purposes of this Section
402(5) and Section 403, the "Trustee") pursuant to clause (4) of Section 402 in
respect of any Outstanding Securities of any series and any Coupons appertaining
thereto shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and any Coupons appertaining thereto 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

                                       36
<PAGE>
 
determine, to the Holders of such Securities and any Coupons appertaining
thereto of all sums due and to become due thereon in respect of principal (and
premium, if any) and interest and Additional Amounts, if any, but such money
need not be segregated from other funds except to the extent required by law.

         Unless otherwise specified in or pursuant to this Indenture or any
Securities, if, after a deposit referred to in Section 402(4)(a) has been made,
(a) the Holder of a Security in respect of which such deposit was made is
entitled to, and does, elect pursuant to Section 301 or the terms of such
Security to receive payment in a Currency other than that in which the deposit
pursuant to Section 402(4)(a) has been made in respect of such Security, or (b)
a Conversion Event occurs in respect of the Foreign Currency in which the
deposit pursuant to Section 402(4)(a) has been made, the indebtedness
represented by such Security and any Coupons appertaining thereto shall be
deemed to have been, and will be, fully discharged and satisfied through the
payment of the principal of (and premium, if any), and interest, if any, on, and
Additional Amounts, if any, with respect to, such Security as the same becomes
due out of the proceeds yielded by converting (from time to time as specified
below in the case of any such election) the amount or other property deposited
in respect of such Security into the Currency in which such Security becomes
payable as a result of such election or Conversion Event based on (x) in the
case of payments made pursuant to clause (a) above, the applicable market
exchange rate for such Currency in effect on the second Business Day prior to
each payment date, or (y) with respect to a Conversion Event, the applicable
market exchange rate for such Foreign Currency in effect (as nearly as feasible)
at the time of the Conversion Event.

         The Company shall pay and indemnify the Trustee against any tax, fee or
other charge, imposed on or assessed against the Government Obligations
deposited pursuant to this Section 402 or the principal or interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of such Outstanding Securities and any Coupons
appertaining thereto.

         Anything in this Section 402 to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or Government Obligations (or other property and any proceeds
therefrom) held by it as provided in clause (4) of this Section 402 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 a defeasance or covenant defeasance, as applicable, in accordance with
this Section 402.

         Section 403.     Application of Trust Money.

         Subject to the provisions of the last paragraph of Section 1003, all
money and Government Obligations deposited with the Trustee (or other qualifying
Trustee) pursuant to Section 401 or 402 shall be held in trust and applied by
it, in accordance with the provisions of the Securities, the Coupons 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 (or other
qualifying Trustee) may determine, to the Persons entitled thereto, of the
principal, premium, interest and Additional Amounts for whose payment such money
has or Government Obligations have been deposited with

                                       37
<PAGE>
 
or received by the Trustee (or other qualifying Trustee); but such money and
Government Obligations need not be segregated from other funds except to the
extent required by law.

         Section 404.     Qualifying Trustee.

         Any trustee appointed pursuant to Section 402 for the purpose of
holding money or Government Obligations deposited pursuant to that Section shall
be appointed under an agreement in form acceptable to the Trustee and shall
provide to the Trustee a certificate of such trustee, upon which certificate the
Trustee shall be entitled to conclusively rely, that all conditions precedent
provided for herein to the related defeasance or covenant defeasance have been
complied with. In no event shall the Trustee be liable for any acts or omissions
of said trustee.

         Section 405.     Reinstatement.

         If the Trustee (or other qualifying trustee) is unable to apply any
money or Government Obligations in accordance with Section 401 or 402, as
applicable, by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, the
Company's obligations under this Indenture, the Securities and the Coupons, if
any, appertaining thereto shall be revived and reinstated as though no deposit
had occurred pursuant to Section 401 or 402 until such time as the Trustee (or
other qualifying trustee) is permitted to apply all such money or Government
Obligations in accordance with Section 401 or 402, as applicable; provided,
however, that if the Company has made any payment of principal of or any premium
or interest on any Securities or Coupons because of the reinstatement of its
obligations, the Company shall be subrogated to the rights of the Holders of
such Securities or Coupons to receive such payment from the money or Government
Obligations held by the Trustee (or other qualifying trustee).

         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 specifically deleted or modified in or pursuant to the
supplemental indenture, Board Resolution or Officers' Certificate establishing
the terms of such series pursuant to this Indenture:

                  (1) default in the payment of any interest on, or any
         Additional Amounts payable in respect of any interest on, any Security
         of such series when such interest or such

                                       38
<PAGE>

         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 the Trustee or the Holders of
not less than 25% in principal amount of the Outstanding Securities of such
series may declare the principal of all the Securities of such series, or such
lesser amount as may be provided for in the Securities of such series, to be due
and payable immediately, by a notice in writing to the Company (and to the
Trustee if given by the Holders), and upon any such declaration such principal
or such lesser amount shall become immediately due and payable.

         At any time after Securities of any series have been accelerated 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 not less
than a majority in principal amount of the Outstanding Securities of such
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 of money
              sufficient to pay

                  (a) all overdue installments of any interest on any 
              Securities of such series and any Coupons appertaining thereto and
              any Additional Amounts with respect thereto,

                   (b) the principal of and any premium on any Securities
              of such series which have become due otherwise than by such
              declaration of acceleration and any Additional Amounts with
              respect thereto and, to the extent the payment of such interest is
              lawful, interest thereon at the rate or rates borne by or provided
              for in such Securities,

                   (c) to the extent that payment of such interest is lawful, 
              interest upon overdue installments of any interest and any
              Additional Amounts with respect thereto at the rate or rates borne
              by or provided for in such Securities, and

                                      40
<PAGE>
 
                   (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 all other
              amounts due the Trustee under Section 606; and

         (2) all Events of Default with respect to Securities of such
     series, other than the non-payment of the principal of, any premium and
     interest on, and any Additional Amounts with respect to Securities of such
     series which shall have become due solely by such declaration of
     acceleration, shall 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 installment of
     interest on or any Additional Amounts payable in respect of any interest
     on, any Security when such interest or Additional Amounts shall have become
     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 any
     premium on, or any Additional Amounts payable in respect of the principal
     of or any premium on, any Security at its Maturity,

the Company shall, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities and any Coupons appertaining thereto,
the whole amount of money then due and payable with respect to such Securities
and any Coupons appertaining thereto, with interest upon the overdue principal,
any premium and, to the extent that payment of such interest shall be legally
enforceable, upon any overdue installments of interest and Additional Amounts at
the rate or rates borne by or provided for in such Securities, and, in addition
thereto, such further amount of money 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 and all other
amounts due to the Trustee under Section 606.

         If the Company fails to pay the money it is required to pay the Trustee
pursuant to the preceding paragraph forthwith upon the demand of the Trustee,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the money so due and unpaid, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company or any other obligor upon such Securities and any Coupons
appertaining thereto and collect the monies adjudged or decreed to be payable in
the manner provided by law out of the property of the Company or any other
obligor upon such Securities and any Coupons appertaining thereto, wherever
situated.


                                      41
<PAGE>
 
         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
and any Coupons appertaining thereto 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 such Securities or in aid of the exercise of any power granted
herein or therein, or to enforce any other proper remedy.


         Section 504. Trustee may File Proofs of Claim.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of any overdue principal, premium, interest or
Additional Amounts) shall be entitled and empowered, by intervention in such
proceeding or otherwise,

                  (1) to file and prove a claim for the whole amount, or such
         lesser amount as may be provided for in the Securities of such series,
         of the principal and any premium, interest and Additional Amounts owing
         and unpaid in respect of the Securities and any Coupons appertaining
         thereto and to file such other papers or documents as may be necessary
         or advisable in order to have the claims of the Trustee (including any
         claim for the reasonable compensation, expenses, disbursements and
         advances of the Trustee, its agents or counsel) and of the Holders of
         Securities or any Coupons allowed in such judicial proceeding, and

                  (2) to collect and receive any monies or other property
         payable 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 of Securities or any Coupons 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 of Securities or any Coupons, to pay to the Trustee any
amount due to 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 606.

         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder of a Security
or any Coupon any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or Coupons or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Holder of a
Security or any Coupon in any such proceeding.

         All rights of action and claims under this Indenture or any of the
Securities or Coupons may be prosecuted and enforced by the Trustee without the
possession of any of the Securities or Coupons 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 or judgment, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, shall be for the ratable benefit of each and every Holder of a
Security or Coupon in respect of which such judgment has been recovered.


         Section 506.  Application of Money Collected.

         Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal, or any
premium, interest or Additional Amounts, upon presentation of the Securities or
Coupons, or both, as the case may be, and the notation thereon of the payment if

         of any kind, according to the aggregate amounts due and payable on such
         Securities and Coupons for principal and any premium, interest and
         Additional Amounts, respectively;

                  THIRD: The balance, if any, to the Person or Persons entitled
         thereto.


         Section 507.  Limitations on Suits.

thereto shall have any right to institute any proceeding, judicial or otherwise,
with respect to this Indenture, or for the appointment of a receiver or trustee,
or for any other remedy hereunder, unless

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

                  (2) the Holders of not less than 25% in principal amount of
         the Outstanding Securities of such 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;


                                      43
<PAGE>
 
                  (3) such Holder or Holders have offered to the Trustee
         reasonable indemnity against the costs, expenses and liabilities to be
         incurred in compliance with such request;

                  (4) the Trustee for 60 days after its receipt of such notice,
         request and offer of indemnity has failed to institute any such
         proceeding; and

                  (5) no direction inconsistent with such written request has
         been given to the Trustee during such 60-day period by the Holders of a
         majority in principal amount of the Outstanding Securities of such
         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 or any Security to affect, disturb or prejudice the rights of
any other such Holders or Holders of Securities of any other series, 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 such Holders.


         Section 508.  Unconditional Right of Holders to Receive Principal and
                       Any Premium, Interest and Additional Amounts.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security or Coupon shall have the right, which is absolute and
unconditional, to receive payment of the principal of, any premium and (subject
to Sections 305 and 307) interest on, and any Additional Amounts with respect to
such Security or such Coupon, as the case may be, on the respective Stated
Maturity or Maturities therefor specified in such Security or Coupon (or, in the
case of redemption, on the Redemption Date or, in the case of repayment at the
option of such Holder if provided in or pursuant to this Indenture, on the date
such repayment is due) and to institute suit for the enforcement of any such
payment, and such right shall not be impaired without the consent of such
Holder.


         Section 509.  Restoration of Rights and Remedies.

         If the Trustee or any Holder of a Security or a Coupon 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 the Company, the Trustee and each such Holder shall, subject to any
determination in such proceeding, be restored severally and respectively to
their former positions hereunder, and thereafter all rights and remedies of the
Trustee and each such Holder shall continue as though no such proceeding had
been instituted.


         Section 510. Rights and Remedies Cumulative.

                                      44
<PAGE>
 
remedy herein conferred upon or reserved to the Trustee or to each and every
Holder of a Security or a Coupon is intended to be exclusive of any other right
or remedy, and every right and remedy, to the extent permitted by law, shall 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, to the
extent permitted by law, 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 Security or
Coupon 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 any Holder of a Security or a Coupon may be
exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by such Holder, as the case may be.


         Section 512. Control by Holders of Securities.

         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 and any Coupons appertaining thereto, provided that

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

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

                  (3) such direction is not unduly prejudicial to the rights of
         the other Holders of Securities of such series not joining in such
         action, and

                  (4) subject to the provisions of Section 601, the Trustee
         shall have the right to decline to follow any such direction if the
         Trustee in good faith shall, by a Responsible Officer or Officers of
         the Trustee, determine that the proceeding so directed would involve
         the Trustee in personal liability.


         Section 513. Waiver of Past Defaults.

         The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series on behalf of the Holders of all the
Securities of such series and any Coupons appertaining thereto may waive any
past default hereunder with respect to such series and its consequences, except
a default

                                       45
<PAGE>
 
                  (1) in the payment of the principal of, any premium or
         interest on, or any Additional Amounts with respect to, any Security of
         such series or any Coupons appertaining thereto, 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. Waiver of Stay or Extension Laws.

         The Company covenants that (to the extent that it may lawfully do so)
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any 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 expressly waives (to the extent
that it may lawfully do so) 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 515. Undertaking for Costs.

         All parties to this Indenture agree, and each Holder of any Security by
his acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, 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 or
omitted by it as Trustee, the filing by any party litigant in such suit of any
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit having due regard to the merits and good
faith of the claims or defenses made by such party litigant; but the provisions
of this Section 515 shall not apply to any suit instituted by the Trustee, to
any suit instituted by any Holder, or group of Holders, holding in the aggregate
more than 10% in principal amount of Outstanding Securities of any series, or to
any suit instituted by any Holder for the enforcement of the payment of the
principal of (or premium, if any) or interest, if any, on or Additional Amounts,
if any, with respect to any Security on or after the respective Stated
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date, and, in the case of repayment, on or after the date
for repayment) or for the enforcement of the right, if any, to convert or
exchange any Security into Common Stock or other securities in accordance with
its terms.

         Trustee shall determine to make such further inquiry or investigation,
         it shall be entitled to examine, during business hours and upon
         reasonable notice, the books, records and premises of the Company,
         personally or by agent or attorney;

                  (7) the Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or by or
         through agents or attorneys and the Trustee shall not

                                       47
<PAGE>
 
         be responsible for any misconduct or negligence on the part of any
         agent or attorney appointed with due care by it hereunder; and

                  (8) 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.


         Section 602. Notice of Defaults.

         Within 90 days after the occurrence of any default hereunder with
respect to the Securities of any series, the Trustee shall transmit by mail to
all Holders of Securities of such series entitled to receive reports pursuant to
Section 703(3), notice of such default hereunder known to the Trustee, unless
such default shall have been cured or waived; provided, however, that, except in
the case of a default in the payment of the principal of (or premium, if any),
or interest, if any, on, or Additional Amounts or any sinking fund or purchase
fund installment with respect to, any Security of such series, the Trustee shall
be protected in withholding such notice if and so long as the board of
directors, the executive committee or a trust committee of directors and/or
Responsible Officers of the Trustee in good faith determine that the withholding
of such notice is in the best interest of the Holders of Securities and Coupons
of such series; and provided, further, that in the case of any default of the
character specified in Section 501(4) with respect to Securities of such series,
no such notice to Holders shall be given until at least 30 days after the
occurrence thereof. For the purpose of this Section, the term "Default" means
any event which is, or after notice or lapse of time or both would become, an
Event of Default with respect to Securities of such series.


         Section 603. Not Responsible for Recitals or Issuance of Securities.

         The recitals contained herein and in the Securities, except the
Trustee's certificate of authentication, and in any Coupons shall be taken as
the statements of the Company and neither the Trustee nor any Authenticating
Agent assumes any responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Securities or the Coupons, except that the Trustee represents that it is duly
authorized to execute and deliver this Indenture, authenticate the Securities
and perform its obligations hereunder and that the statements made by it in a
Statement of Eligibility on Form T-1 supplied to the Company are true and
accurate, subject to the qualifications set forth therein. Neither the Trustee
nor any Authenticating Agent shall be accountable for the use or application by
the Company of the Securities or the proceeds thereof.


         Section 604. May Hold Securities.

         The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other Person that may be an agent of the Trustee or the
Company, in its individual or any other capacity, may become the owner or
pledgee of Securities or Coupons and, subject to Sections 310(b)

                                       48
<PAGE>
 
and 311 of the Trust Indenture Act, may otherwise deal with the Company with the
same rights it would have if it were not Trustee, Authenticating Agent, Paying
Agent, Security Registrar or such other Person.


         Section 605. Money Held in Trust.

         Except as provided in Section 403 and Section 1003, money held by the
Trustee in trust hereunder need not be segregated from other funds except to the
extent required by law and shall be held uninvested. The Trustee shall be under
no liability for interest on any money received by it hereunder except as
otherwise agreed in writing with the Company.


         Section 606. Compensation and Reimbursement.

         The Company agrees:

                  (1) to pay to the Trustee from time to time reasonable
         compensation for all services rendered by the Trustee hereunder (which
         compensation shall not be limited by any provision of law in regard to
         the compensation of a trustee of an express trust);

                  (2) except as otherwise expressly provided herein, to
         reimburse the Trustee upon its request for all reasonable expenses,
         disbursements and advances incurred or made by the Trustee in
         accordance with any provision of this Indenture (including the
         reasonable compensation and the expenses and disbursements of its
         agents and counsel), except any such expense, disbursement or advance
         as may be attributable to the Trustee's negligence or bad faith; and

                  (3) to indemnify the Trustee and its agents for, and to hold
         them harmless against, any loss, liability or expense incurred without
         negligence or bad faith on their part, arising out of or in connection
         with the acceptance or administration of the trust or trusts hereunder,
         including the costs and expenses of defending themselves against any
         claim or liability in connection with the exercise or performance of
         any of their powers or duties hereunder, except to the extent that any
         such loss, liability or expense was due to the Trustee's negligence or
         bad faith.

         As security for the performance of the obligations of the Company under
this Section, the Trustee shall have a lien prior to the Securities of any
series upon all property and funds held or collected by the Trustee as such,
except funds held in trust for the payment of principal of, and premium or
interest on or any Additional Amounts with respect to particular Securities or
any Coupons appertaining thereto.

         Without limiting any rights available to the Trustee under applicable
law, any compensation or expense incurred by the Trustee after a default
specified by Section 501(5) or (6) is intended to constitute an expense of
administration under any then applicable bankruptcy or insolvency law.

                                       49

"Trustee" for purposes of this Section 606 shall include any predecessor Trustee
but the negligence or bad faith of any Trustee shall not affect the rights of
any other Trustee under this Section 606.


         Section 607. Corporate Trustee Required; Eligibility.

         There shall at all times be a Trustee hereunder that is a Corporation,

accordance with Section 310(a)(2) of the Trust Indenture Act) of at least
$50,000,000 subject to supervision or examination by Federal or state authority.
If at any time the Trustee shall cease to be 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 608. Resignation and Removal; Appointment of Successor.

         (1) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee pursuant to Section 609.

         (2) 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 609 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 such
series.

         (3) 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 the
Company.

         (4) If at any time:

             (a) the Trustee shall fail to comply with the obligations
         imposed upon it under Section 310(b) of the Trust Indenture Act
         (subject to the penultimate paragraph thereof) with respect to
         Securities of any series after written request therefor by the Company
         or any Holder of a Security of such series who has been a bona fide
         Holder of a Security of such series for at least six months, or

             (b) the Trustee shall cease to be eligible under Section 607
         and shall fail to resign after written request therefor by the Company
         or any such Holder, or

                                       50
<PAGE>
 
             (c) 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 with respect to all Securities or the Securities of such
series, or (ii) subject to Section 315(e) of the Trust Indenture Act, any Holder
of a Security 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 removal of the Trustee with
respect to all Securities of such series and the appointment of a successor
Trustee or Trustees.

         (5) 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 609. 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
609, 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 of Securities and accepted
appointment in the manner required by Section 609, any Holder of a Security 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.

         (6) 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 by mailing
written notice of such event by first-class mail, postage prepaid, to the
Holders of Registered Securities, if any, of such series as their names and
addresses appear in the Security Register and, if Securities of such series are
issued as Bearer Securities, by publishing notice of such event once in an
Authorized Newspaper in each Place of Payment located outside the United States.
Each notice shall include the name of the successor Trustee with respect to the
Securities of such series and the address of its Corporate Trust Office.


         Section 609. Acceptance of Appointment by Successor.

         (1) Upon the appointment hereunder of any successor Trustee with
respect to all Securities, such successor Trustee so appointed shall execute,
acknowledge and deliver to the

                                       51
<PAGE>
 
Company and 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
hereunder of the retiring Trustee; but, on the request of the Company or such
successor Trustee, such retiring Trustee, upon payment of its charges, shall
execute and deliver an instrument transferring to such successor Trustee all the
rights, powers and trusts of the retiring Trustee and, subject to Section 1003,
shall duly assign, transfer and deliver to such successor Trustee all property
and money held by such retiring Trustee hereunder, subject nevertheless to its
lien, if any, provided for in Section 606.

         (2) Upon the appointment hereunder of any successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and such successor Trustee 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, such 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, 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 that no
Trustee shall be responsible for any notice given to, or received by, or any act
or failure to act on the part of any other Trustee hereunder, 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, such retiring Trustee shall have no further responsibility for the
exercise of rights and powers or for the performance of the duties and
obligations vested in the Trustee under this Indenture with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates other than as hereinafter expressly set forth, 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
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 such
successor Trustee, such retiring Trustee, upon payment of its charges with
respect to the Securities of that or those series to which the appointment of
such successor relates and subject to Section 1003 shall duly assign, transfer
and deliver to such successor Trustee, to the extent contemplated by such
supplemental indenture, the 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, subject to its lien, if any,
provided for in Section 606.

         (3) Upon request of any Person appointed hereunder as a 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 (1) or (2) of this Section, as the
case may be.

                                       52
<PAGE>
 
         (4) No Person shall accept its appointment hereunder as a successor
Trustee unless at the time of such acceptance such successor Person shall be
qualified under the Trust Indenture Act and eligible under this Article.


         Section 610. 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 of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
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 611. Appointment of Authenticating Agent.

         The Trustee may appoint one or more Authenticating Agents acceptable to
the Company with respect to one or more series of Securities which shall be
authorized to act on behalf of the Trustee to authenticate Securities of that or
those series issued upon original issue, exchange, registration of transfer,
partial redemption or partial repayment, 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,
except as provided in or pursuant to this Indenture, shall at all times be a
corporation that would be permitted by the Trust Indenture Act to act as trustee
under an indenture qualified under the Trust Indenture Act, is authorized under
applicable law and by its charter to act as an Authenticating Agent and has a
combined capital and surplus (computed in accordance with Section 310(a)(2) of
the Trust Indenture Act) of at least $50,000,000. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, it 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 of
the corporate agency or corporate trust business of an Authenticating Agent,
shall be the successor of such Authenticating Agent hereunder, provided such
Corporation

                                       53
<PAGE>
 
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 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 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 (i) mail written notice
of such appointment by first-class mail, postage prepaid, to all Holders of
Registered Securities, if any, of the series with respect to which such
Authenticating Agent shall serve, as their names and addresses appear in the
Security Register, and (ii) if Securities of the series are issued as Bearer
Securities, publish notice of such appointment at least once in an Authorized
Newspaper in the place where such successor Authenticating Agent has its
principal office if such office is located outside the United States. 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 Company agrees to pay each Authenticating Agent from time to time
reasonable compensation for its services under this Section. If the Trustee
makes such payments, it shall be entitled to be reimbursed for such payments,
subject to the provisions of Section 606.

         The provisions of Sections 308, 603 and 604 shall be applicable to each
Authenticating Agent.

         If an Authenticating Agent is appointed with respect to one or more
series of Securities 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 alternate certificate of authentication in substantially the
following form:

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

         [Date]           THE CHASE MANHATTAN BANK,

                            --------------------------------------------------

         If all of the Securities of any series may not be originally issued at
one time, and if the Trustee does not have an office capable of authenticating
Securities upon original issuance located in a Place of Payment where the
Company wishes to have Securities of such series authenticated upon original
issuance, the Trustee, if so requested in writing (which writing need not be
accompanied by or contained in an Officers' Certificate by the Company), shall
appoint in accordance with this Section and such procedures as shall be
acceptable to the Trustee an Authenticating Agent having an office in a Place of
Payment designated by the Company with respect to such series of Securities.

         administration of the trusts hereunder by more than one Trustee,
         pursuant to the requirements of Section 609; or

         Securities of any series then Outstanding or any Coupons appertaining
         thereto in any material respect; or

                                       58
<PAGE>
 
                  (7) to add to, delete from or revise the conditions,

         material respect; or

                  (10) to secure the Securities pursuant to Section 1006 or

                  (12) to amend or supplement any provision contained herein or
         in any supplemental indenture (which amendment or supplement may apply
         to one or more series of Securities or to one or more Securities within
         any series as specified in such supplemental indenture or indentures),
         provided that such amendment or supplement does not apply to any
         Outstanding Security issued prior to the date of such supplemental
         indenture and entitled to the benefits of such provision.


         Section 902. Supplemental Indentures with Consent of Holders.

         With the consent of the Holders of not less than a majority in
principal amount of the Outstanding Securities of each series affected by such
supplemental indenture, by Act of said Holders delivered to the Company and the
Trustee, the Company (when authorized by or pursuant to a Board Resolution), and
the Trustee may enter into an indenture or indentures supplemental hereto for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of this Indenture or of the Securities of such series or
of modifying in any manner the rights of the Holders of Securities of such
series under this Indenture; provided, however, that no such supplemental
indenture, without the consent of the Holder of each Outstanding Security
affected thereby, shall

                  (1) change the Stated Maturity of the principal of, or any
         premium or installment of interest on or any Additional Amounts with
         respect to, any Security, or reduce the principal amount thereof or the
         rate (or modify the calculation of such rate) of interest thereon or
         any Additional Amounts with respect thereto, or any premium payable
         upon the redemption thereof or otherwise, or change the obligation of
         the Company to pay Additional Amounts pursuant to Section 1004, or
         reduce the amount of the principal of an Original Issue Discount
         Security that would be due and payable upon a declaration of
         acceleration of the Maturity thereof pursuant to Section 502 or the
         amount thereof provable in bankruptcy

                                       59
<PAGE>
 
         pursuant to Section 504, adversely affect the right of repayment at the
         option of any Holder as contemplated by Article Thirteen, or change the
         Place of Payment, Currency in which the principal of, any premium or
         interest on, or any Additional Amounts with respect to any Security 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, in the case of
         repayment at the option of the Holder, on or after the date for
         repayment), or

                  (2) reduce the percentage in principal amount of the
         Outstanding Securities of any series, the consent of whose Holders is
         required for any such supplemental indenture, or the consent of whose
         Holders is required for any waiver of certain defaults hereunder and
         their consequences provided for in this Indenture, or reduce the
         requirements of Section 1504 for quorum or voting, or

                  (3) modify any of the provisions of this Section or Section
         513, except to increase any such percentage 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, or

                  (4) make any change that adversely affects the right to
         convert or exchange any Security for Common Stock or other securities
         in accordance with its terms.

         A supplemental indenture which changes or eliminates any covenant or
other provision of this Indenture which shall have been included expressly and
solely for the benefit of one or more particular series of Securities, or which
modifies the rights of the Holders of Securities of such series with respect to
such covenant or other provision, shall be deemed not to affect the rights under
this Indenture of the Holders of Securities of any other series.

         It shall not be necessary for any Act of Holders of Securities under
this Section to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such Act shall approve the substance
thereof.


         Section 903. Execution of Supplemental Indentures.

         As a condition to executing, or accepting the additional trusts created
by, any supplemental indenture permitted by this Article or the modifications
thereby of the trust created by this Indenture, the Trustee shall be entitled to
receive, and (subject to Section 315 of the Trust Indenture Act) shall be fully
protected in relying upon, an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture. The
Trustee may, but shall not be obligated to, enter into any such supplemental
indenture which affects the 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,
this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of a Security theretofore or thereafter authenticated and delivered hereunder
and of any Coupon appertaining thereto shall be bound thereby.


         Section 905.  Reference in Securities to Supplemental Indentures.

         Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to this Article may, and shall
if required by the Trustee, bear a notation in form approved by the Trustee as
to any matter provided for in such supplemental indenture. If the Company shall
so determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee and the Company, to any such supplemental indenture may
be prepared and executed by the Company and authenticated and delivered by the
Trustee in exchange for Outstanding Securities of such series.


         Section 906.  Conformity with Trust Indenture Act.

         Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act as then in effect.


                                  ARTICLE TEN

                                   COVENANTS


         Section 1001.   Payment of Principal, Any Premium, Interest and
                         Additional Amounts.


         The Company covenants and agrees for the benefit of the Holders of the
Securities of each series that it will duly and punctually pay the principal of,
any premium and interest on and any Additional Amounts with respect to the
Securities of such series in accordance with the terms thereof, any Coupons
appertaining thereto and this Indenture. Any interest due on any Bearer Security
on or before the Maturity thereof, and any Additional Amounts payable with
respect to such interest, shall be payable only upon presentation and surrender
of the Coupons appertaining thereto for such interest as they severally mature.


         Section 1002.   Maintenance of Office or Agency.

         The Company shall maintain in each Place of Payment for any series of
Securities an Office or Agency where Securities of such series (but not Bearer
Securities, except as otherwise provided

                                       61
<PAGE>
 
below, unless such Place of Payment is located outside the United States) may be
presented or surrendered for payment, where Securities of such series may be
surrendered for registration of transfer or exchange, where Securities of such
series that are convertible or exchangeable may be surrendered for conversion or
exchange, and where notices and demands to or upon the Company in respect of the
Securities of such series relating thereto and this Indenture may be served. If
Securities of a series are issuable as Bearer Securities, the Company shall
maintain, subject to any laws or regulations applicable thereto, an Office or
Agency in a Place of Payment for such series which is located outside the United
States where Securities of such series and any Coupons appertaining thereto may
be presented and surrendered for payment; provided, however, that if the
Securities of such series are listed on The Stock Exchange of the United Kingdom
and the Republic of Ireland or the Luxembourg Stock Exchange or any other stock
exchange located outside the United States and such stock exchange shall so
require, the Company shall maintain a Paying Agent in London, Luxembourg or any
other required city located outside the United States, as the case may be, so
long as the Securities of such series are listed on such exchange. 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,
except that Bearer Securities of such series and any Coupons appertaining
thereto may be presented and surrendered for payment at the place specified for
the purpose with respect to such Securities as provided in or pursuant to this
Indenture, and the Company hereby appoints the Trustee as its agent to receive
all such presentations, surrenders, notices and demands.

         Except as otherwise provided in or pursuant to this Indenture, no
payment of principal, premium, interest or Additional Amounts with respect to
Bearer Securities shall be made at any Office or Agency in the United States or
by check mailed to any address in the United States or by transfer to an account
maintained with a bank located in the United States; provided, however, if
amounts owing with respect to any Bearer Securities shall be payable in Dollars,
payment of principal of, any premium or interest on and any Additional Amounts
with respect to any such Security may be made at the Corporate Trust Office of
the Trustee or any Office or Agency designated by the Company in the Borough of
Manhattan, The City of New York, if (but only if) payment of the full amount of
such principal, premium, interest or Additional Amounts at all offices outside
the United States maintained for such purpose by the Company in accordance with
this Indenture is illegal or effectively precluded by exchange controls or other
similar restrictions.

         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 shall 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. Unless otherwise provided in or pursuant to this
Indenture, the Company hereby designates as the Place of Payment for each series
of Securities the Borough of Manhattan, The City of New York, and initially
appoints the Corporate Trust Office of the Trustee as the Company's Office or
Agency in the Borough of Manhattan, The

                                       62
<PAGE>
 
City of New York for such purpose. The Company may subsequently appoint a
different Office or Agency in the Borough of Manhattan, The City of New York for
the Securities of any series.


         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 shall, on or before each due date of the
principal of, any premium or interest on or Additional Amounts with respect to
any of the Securities of such series, segregate and hold in trust for the
benefit of the Persons entitled thereto a sum 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
principal or any premium, interest or Additional Amounts so becoming due until
such sums shall be paid to such Persons or otherwise disposed of as herein
provided, and shall 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 shall, on or prior to each due date of the principal
of, any premium or interest on or any Additional Amounts with respect to any
Securities of such series, deposit with any Paying Agent a sum (in the Currency
or Currencies described in the preceding paragraph) sufficient to pay the
principal or any premium, interest or Additional Amounts so becoming due, such
sum to be held in trust for the benefit of the Persons entitled thereto, 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 shall 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 shall:

                  (1)     hold all sums held by it for the payment of the
         principal of, any premium or interest on or any Additional Amounts with
         respect to Securities of such series in trust for the benefit of the
         Persons entitled thereto until such sums shall be paid to such Persons
         or otherwise disposed of as provided in or pursuant to this Indenture;

                  (2)     give the Trustee notice of any default by the Company
         (or any other obligor upon the Securities of such series) in the making
         of any payment of principal, any premium or interest on or any
         Additional Amounts with respect to the Securities of such series; and

                  (3)     at any time during the continuance of any such
         default, upon the written request of the Trustee, forthwith pay to the
         Trustee all sums so held in trust by such Paying Agent.

         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 terms 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 sums.

                                       63
<PAGE>
 
         Except as otherwise provided herein or pursuant hereto, 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, any premium or interest on or any
Additional Amounts with respect to any Security of any series or any Coupon
appertaining thereto and remaining unclaimed for two years after such principal
or any such premium or interest or any such Additional Amounts shall have 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 or any Coupon appertaining thereto 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 an Authorized Newspaper in each Place of Payment for such
series or to be mailed to Holders of Registered Securities of such series, or
both, 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
or mailing nor shall it be later than two years after such principal and any
premium or interest or Additional Amounts shall have become due and payable, any
unclaimed balance of such money then remaining will be repaid to the Company.


         Section 1004.     Additional Amounts.

         If any Securities of a series provide for the payment of Additional
Amounts, the Company agrees to pay to the Holder of any such Security or any
Coupon appertaining thereto Additional Amounts as provided in or pursuant to
this Indenture or such Securities. Whenever in this Indenture there is
mentioned, in any context, the payment of the principal of or any premium or
interest on, or in respect of, any Security of any series or any Coupon or the
net proceeds received on the sale or exchange of any Security of any series,
such mention shall be deemed to include mention of the payment of Additional
Amounts provided by the terms of such series established hereby or pursuant
hereto to the extent that, in such context, Additional Amounts are, were or
would be payable in respect thereof pursuant to such terms, and express mention
of the payment of Additional Amounts (if applicable) in any provision hereof
shall not be construed as excluding Additional Amounts in those provisions
hereof where such express mention is not made.

         Except as otherwise provided in or pursuant to this Indenture or the
Securities of any series, if the Securities of a series provide for the payment
of Additional Amounts, at least 10 days prior to the first Interest Payment Date
with respect to such series of Securities (or if the Securities of such series
shall not bear interest prior to Maturity, the first day on which a payment of
principal is made), and at least 10 days prior to each date of payment of
principal or interest if there has been any change with respect to the matters
set forth in the below-mentioned Officers' Certificate, the Company shall
furnish to the Trustee and the principal Paying Agent or Paying Agents, if other
than the Trustee, an Officers' Certificate instructing the Trustee and such
Paying Agent or Paying Agents whether such payment of principal of and premium,
if any, or interest, if any, on the Securities of such series shall be made to
Holders of Securities of such series or the Coupons appertaining thereto who are
United States Aliens without withholding for or on account of any tax,
assessment or other governmental charge described in the Securities of such
series. If any such withholding shall be required, then such Officers'
Certificate shall specify by country the amount, if any, required to be

                                       64
<PAGE>
 
withheld on such payments to such Holders of Securities or Coupons, and the
Company agrees to pay to the Trustee or such Paying Agent the Additional Amounts
required by the terms of such Securities. The Company covenants to indemnify the
Trustee and any Paying Agent for, and to hold them harmless against, any loss,
liability or expense reasonably incurred without negligence or bad faith on
their part arising out of or in connection with actions taken or omitted by any
of them in reliance on any Officers' Certificate furnished pursuant to this
Section.


         Section 1005.  Company Statement as to Compliance.

         The Company will deliver to the Trustee, within 120 days after the end
of each fiscal year, an Officers' Certificate (which need not comply with
Section 102), stating as to each signer, that

                  (1)     a review of the activities of the Company during such
         year and of performance under this Indenture has been made under his or
         her supervision; and

                  (2)      to the best of his or her knowledge, based on such
         review, (a) the Company has fulfilled all its obligations under and
         complied with all covenants and conditions contained in this Indenture
         throughout such year, or, if there has been a default in the
         fulfillment of any such covenant, condition or obligation, specifying
         each such default known to him or her and the nature and status
         thereof, and (b) no event has occurred and is continuing which is, or
         after notice or lapse of time or both would become, an Event of Default
         under Section 501, or, if such an event has occurred and is continuing,
         specifying each such event known to him or her and the nature and
         status thereof.

At least one of the Person's signing such Officers' Certificate shall be the

                            REDEMPTION OF SECURITIES


         Section 1101.       Applicability of Article.

         Redemption of Securities of any series at the option of the Company as
permitted or required by the terms of such Securities shall be made in
accordance with the terms of such Securities and (except as otherwise provided
herein or pursuant hereto) 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. In case of any redemption at the election
of the Company of less than all of the Securities of any series, the Company
shall, at least 60 days prior to the Redemption Date fixed by

                                       65
<PAGE>
 
the Company (unless a shorter notice shall be satisfactory to the Trustee),
notify the Trustee of such Redemption Date and of the principal amount of
Securities of such series to be redeemed and, in the event that the Company
shall determine that the Securities of any series to be redeemed shall be
selected from Securities of such series having the same issue date, interest
rate or interest rate formula, Stated Maturity and other terms (the "Equivalent
Terms"), the Company shall notify the Trustee of such Equivalent Terms. In the
case of any redemption of Securities (a) prior to the expiration of any
restriction on such redemption provided in the terms of such Securities or
elsewhere in this Indenture or (b) pursuant to an election of the Company which
is subject to a condition specified 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 or condition.


         Section 1103.       Selection by Trustee of Securities to be Redeemed.

         If less than all of the Securities of any series are to be redeemed
(unless all of the Securities of any series with Equivalent Terms are to be
redeemed) or if less than all of the Securities of any series with Equivalent
Terms 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 or from the Outstanding Securities of
such series with Equivalent Terms, as the case may be, 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 of portions of the principal
amount of Registered Securities of such series; provided, however, that no such
partial redemption shall reduce the portion of the principal amount of a
Registered Security of such series not redeemed to less than the minimum
denomination for a Security of such series established herein or pursuant
hereto.

         The Trustee shall promptly notify the Company and the Security
Registrar (if other than itself) 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 of such Securities which has been or is to be redeemed.

         Unless otherwise specified in or pursuant to this Indenture or the
Securities of any series, if any Security selected for partial redemption is
converted or exchanged for Common Stock or other securities in part before
termination of the conversion or exchange right with respect to the portion of
the Security so selected, the converted or exchanged portion of such Security
shall be deemed (so far as may be) to be the portion selected for redemption.
Securities which have been converted or exchanged during a selection of
Securities to be redeemed shall be treated by the Trustee as Outstanding for the
purpose of such selection.

         Section 1104.       Notice of Redemption.

         Notice of redemption shall be given in the manner provided in Section
106, not less than 30 nor more than 60 days prior to the Redemption Date, unless
a shorter period is specified in the Securities to be redeemed, to the Holders
of Securities to be redeemed. Failure to give notice by mailing in the manner
herein provided to the Holder of any Registered Securities designated for
redemption as a whole or in part, or any defect in the notice to any such
Holder, shall not affect the validity of the proceedings for the redemption of
any other Securities or portion thereof. Any notice that is mailed to the Holder
of any Registered Securities in the manner herein provided shall be conclusively
presumed to have been duly given, whether or not such Holder receives the
notice.

         All notices of redemption shall state:

                  (1)     the Redemption Date,

                  (2)     the Redemption Price,

                  (3)     if less than all Outstanding Securities of any series
         are to be redeemed (unless all of the Securities of any series with
         Equivalent Terms are to be redeemed), the identification (and, in the
         case of partial redemption, the principal amount) of the particular
         Security or Securities to be redeemed,

                  (4)      in case any Security is to be redeemed in part only,
         the notice which relates to such Security shall state that on and after
         the Redemption Date, upon surrender of such Security, the Holder of
         such Security will receive, without charge, a new Security or
         Securities of authorized denominations for the principal amount thereof
         remaining unredeemed,

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

                  (6)      the place or places where such Securities, together
         (in the case of Bearer Securities) with all Coupons appertaining
         thereto, if any, maturing after the Redemption Date, are to be
         surrendered for payment of the Redemption Price and any accrued
         interest and Additional Amounts pertaining thereto,

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

                  (8)      that, unless otherwise specified in such notice,
         Bearer Securities of any series, if any, surrendered for redemption
         must be accompanied by all Coupons maturing subsequent to the date
         fixed for redemption or the amount of any such missing Coupon or
         Coupons will be deducted from the Redemption Price, unless security or
         indemnity satisfactory to the Company, the Trustee and any Paying Agent
         is furnished,


                                       67
<PAGE>
 
                  (9)      if Bearer Securities of any series are to be redeemed
         and any Registered Securities of such series are not to be redeemed,
         and if such Bearer Securities may be exchanged for Registered
         Securities not subject to redemption on the Redemption Date pursuant to
         Section 305 or otherwise, the last date, as determined by the Company,
         on which such exchanges may be made,

                  (10)     in the case of Securities of any series that are
         convertible or exchangeable into Common Stock or other securities, the
         conversion or exchange price or rate, the date or dates on which the
         right to convert or exchange the principal of the Securities of such
         series to be redeemed will commence or terminate and the place or
         places where such Securities may be surrendered for conversion or
         exchange, and

                  (11)     the CUSIP number or the Euroclear or the Cedel
         reference numbers of such Securities, if any (or any other numbers used
         by a U.S. Depository or Depository to identify such Securities).

         A notice of redemption published as contemplated by Section 106 need
not identify particular Registered Securities to be redeemed.

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


         Section 1105.     Deposit of Redemption Price.

         On or prior to any Redemption Date, the Company shall deposit, with
respect to the Securities of any series called for redemption pursuant to
Section 1104, 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 applicable Currency sufficient to pay
the Redemption Price of, and (except if the Redemption Date shall be an Interest
Payment Date, unless otherwise specified pursuant to Section 301 for or in the
Securities of such series) any accrued interest on and Additional Amounts with
respect thereto, all such 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 and the Coupons for such
interest appertaining to any Bearer Securities so to be redeemed, except to the
extent provided below, shall be void. Upon surrender of any such Security for
redemption in accordance with said notice, together with all Coupons, if any,
appertaining thereto maturing after the Redemption Date, such Security shall be
paid by the Company at the Redemption Price, together with any accrued interest

                                       68
<PAGE>
 
and Additional Amounts to the Redemption Date; provided, however, that, except
as otherwise provided in or pursuant to this Indenture or the Bearer Securities
of such series, installments of interest on Bearer Securities whose Stated
Maturity is on or prior to the Redemption Date shall be payable only upon
presentation and surrender of Coupons for such interest (at an Office or Agency
located outside the United States except as otherwise provided in Section 1002),
and provided, further, that, except as otherwise specified in or pursuant to
this Indenture or the Registered Securities of such series, installments of
interest on Registered Securities 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
Regular Record Dates therefor according to their terms and the provisions of
Section 307.

         If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant Coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing Coupons, or the surrender of such missing
Coupon or Coupons may be waived by the Company and the Trustee if there be
furnished to them such security or indemnity as they may require to save each of
them and any Paying Agent harmless. If thereafter the Holder of such Security
shall surrender to the Trustee or any Paying Agent any such missing Coupon in
respect of which a deduction shall have been made from the Redemption Price,
such Holder shall be entitled to receive the amount so deducted; provided,
however, that any interest or Additional Amounts represented by Coupons shall be
payable only upon presentation and surrender of those Coupons at an Office or
Agency for such Security located outside of the United States except as
otherwise provided in Section 1002.

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


         Section 1107.     Securities Redeemed in Part.

         Any Registered Security which is to be redeemed only in part shall be
surrendered at any Office or Agency for such Security (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 to the Holder of such
Security without service charge, a new Registered Security or Securities of the
same series, containing identical terms and provisions, 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. If a Security in global form is so surrendered, the Company shall
execute, and the Trustee shall authenticate and deliver to the U.S. Depository
or other Depository for such Security in global form as shall be specified in
the Company Order with respect thereto to the Trustee, without service charge, a
new Security in global form in a denomination equal to and in exchange for the
unredeemed portion of the principal of the Security in global form 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 permitted or
required in or pursuant to this Indenture or any Security of such series issued
pursuant to this Indenture.

         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 such 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 and this Indenture.


         Section 1202.     Satisfaction of Sinking Fund Payments with
                           Securities.

         The Company may, in satisfaction of all or any part of any sinking fund
payment with respect to the Securities of any series to be made pursuant to the
terms of such Securities (1) deliver Outstanding Securities of such series
(other than any of such Securities previously called for redemption or any of
such Securities in respect of which cash shall have been released to the
Company), together in the case of any Bearer Securities of such series with all
unmatured Coupons appertaining thereto, and (2) apply as a credit Securities of
such series which have been redeemed either at the election of the Company
pursuant to the terms of such series of Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, 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. If as a result of the delivery or credit of Securities
of any series in lieu of cash payments pursuant to this Section 1202, the
principal amount of Securities of such series to be redeemed in order to exhaust
the aforesaid cash payment shall be less than $100,000, the Trustee need not
call Securities of such series for redemption, except upon Company Request, and
such cash payment shall be held by the Trustee or a Paying Agent and applied to
the next succeeding sinking fund payment, provided, however, that the Trustee or
such Paying Agent shall at the request of the Company from time to time pay over
and deliver to the Company any cash payment so being held by the Trustee or such
Paying Agent upon delivery by the Company to the Trustee of Securities of that
series purchased by the Company having an unpaid principal amount equal to the
cash payment requested to be released to the Company.

         Section 1203.   Redemption of Securities for Sinking Fund.

         Not less than 75 days prior to each sinking fund payment date for any
series of Securities, the Company shall deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing mandatory 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 of
Securities of that series pursuant to Section 1202, the basis for such credit,
that such Securities have not been previously so credited and the optional
amount, if any, to be added in cash to the next ensuing mandatory sinking fund
payment, and will also deliver to the Trustee any Securities to be so credited
and not theretofore delivered. If such Officers' Certificate shall specify an
optional amount to be added in cash to the next ensuing mandatory sinking fund
payment, the Company shall thereupon be obligated to pay the amount therein
specified. Not less than 45 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.


                               ARTICLE THIRTEEN

                      REPAYMENT AT THE OPTION OF HOLDERS


         Section 1301.   Applicability of Article.

         Securities of any series which are repayable at the option of the
Holders thereof before their Stated Maturity shall be repaid in accordance with
the terms of the Securities of such series. The repayment of any principal
amount of Securities pursuant to such option of the Holder to require repayment
of Securities before their Stated Maturity, for purposes of Section 309, shall
not operate as a payment, redemption or satisfaction of the Indebtedness
represented by such Securities unless and until the Company, at its option,
shall deliver or surrender the same to the Trustee with a directive that such
Securities be cancelled. Notwithstanding anything to the contrary contained in
this Section 1301, in connection with any repayment of Securities, the Company
may arrange for the purchase of any Securities by an agreement with one or more
investment bankers or other purchasers to purchase such Securities by paying to
the Holders of such Securities on or before the close of business on the
repayment date an amount not less than the repayment price payable by the
Company on repayment of such Securities, and the obligation of the Company to
pay the repayment price of such Securities shall be satisfied and discharged to
the extent such payment is so paid by such purchasers.

                       SECURITIES IN FOREIGN CURRENCIES


         Section 1401.   Applicability of Article.

         Whenever this Indenture provides for any distribution to Holders of
Securities of any series in which not all of such Securities are denominated in
the same Currency, in the absence of any provision to the contrary in or
pursuant to this Indenture or the Securities of such series, any amount in
respect of any Security denominated in a Currency other than Dollars shall be
treated for any such distribution as that amount of Dollars that could be
obtained for such amount on such reasonable basis of exchange and as of the
record date with respect to Registered Securities of such series (if any) for
such distribution (or, if there shall be no applicable record date, such other
date reasonably proximate to the date of such distribution) as the Company may
specify in a written notice to the Trustee or, in the absence of such written
notice, as the Trustee may determine.

                       MEETINGS OF HOLDERS OF SECURITIES


         Section 1501.    Purposes for Which Meetings may be Called.

         A meeting of Holders of Securities of any series may be called at any
time and from time to time pursuant to this Article to make, give or take any
request, demand, authorization, direction, notice, consent, waiver or other Act
provided by this Indenture to be made, given or taken by Holders of Securities
of such series.


         Section 1502.    Call, Notice and Place of Meetings.

         (1) The Trustee may at any time call a meeting of Holders of Securities
of any series for any purpose specified in Section 1501, to be held at such time
and at such place in the Borough of Manhattan, The City of New York, or, if
Securities of such series have been issued in whole or in part as Bearer
Securities, in London or in such place outside the United States as the Trustee
shall determine. Notice of every meeting of Holders of Securities of any series,
setting forth the time and the place of such meeting and in general terms the
action proposed to be taken at such meeting, shall be given, in the manner
provided in Section 106, not less than 21 nor more than 180 days prior to the
date fixed for the meeting.

         (2) In case at any time the Company (by or pursuant to a Board
Resolution) or the Holders of at least 10% in principal amount of the
Outstanding Securities of any series shall have requested the Trustee to call a
meeting of the Holders of Securities of such series for any purpose specified in
Section 1501, by written request setting forth in reasonable detail the action
proposed to be taken

                                       72
<PAGE>
 
at the meeting, and the Trustee shall not have mailed notice of or made the
first publication of the notice of such meeting within 21 days after receipt of
such request (whichever shall be required pursuant to Section 106) or shall not
thereafter proceed to cause the meeting to be held as provided herein, then the
Company or the Holders of Securities of such series in the amount above
specified, as the case may be, may determine the time and the place in the
Borough of Manhattan, The City of New York, or, if Securities of such series are
to be issued as Bearer Securities, in London for such meeting and may call such
meeting for such purposes by giving notice thereof as provided in clause (1) of
this Section.


         Section 1503.    Persons Entitled to Vote at Meetings.

         To be entitled to vote at any meeting of Holders of Securities of any
series, a Person shall be (1) a Holder of one or more Outstanding Securities of
such series, or (2) a Person appointed by an instrument in writing as proxy for

entitled to vote at such meeting and their counsel, any representatives of the
Trustee and its counsel and any representatives of the Company and its counsel.


         Section 1504.    Quorum; Action.

         The Persons entitled to vote a majority in principal amount of the
Outstanding Securities of a series shall constitute a quorum for a meeting of
Holders of Securities of such series; provided, however, that if any action is
to be taken at such meeting with respect to a consent or waiver which this
Indenture expressly provides may be given by the Holders of at least 66-2/3% in
principal amount of the Outstanding Securities of a series, the Persons entitled
to vote 66-2/3% in principal amount of the Outstanding Securities of such series
shall constitute a quorum. In the absence of a quorum within 30 minutes after
the time appointed for any such meeting, the meeting shall, if convened at the
request of Holders of Securities of such series, be dissolved. In any other case
the meeting may be adjourned for a period of not less than 10 days as determined
by the chairman of the meeting prior to the adjournment of such meeting. In the
absence of a quorum at any such adjourned meeting, such adjourned meeting may be
further adjourned for a period of not less than 10 days as determined by the
chairman of the meeting prior to the adjournment of such adjourned meeting.
Notice of the reconvening of any adjourned meeting shall be given as provided in
Section 1502(1), except that such notice need be given only once not less than
five days prior to the date on which the meeting is scheduled to be reconvened.
Notice of the reconvening of an adjourned meeting shall state expressly the
percentage, as provided above, of the principal amount of the Outstanding

         Except as limited by the proviso to Section 902, any resolution
presented to a meeting or adjourned meeting duly reconvened at which a quorum is
present as aforesaid may be adopted only by the affirmative vote of the Holders
of a majority in principal amount of the Outstanding Securities of that series;
provided, however, that, except as limited by the proviso to Section 902, any
resolution with respect to any consent or waiver which this Indenture expressly
provides may

                                       73
<PAGE>
 
be given by the Holders of at least 66-2/3% in principal amount of the
Outstanding Securities of a series may be adopted at a meeting or an adjourned
meeting duly convened and at which a quorum is present as aforesaid only by the
affirmative vote of the Holders of 66-2/3% in principal amount of the
Outstanding Securities of that series; and provided, further, that, except as
limited by the proviso to Section 902, any resolution with respect to any
request, demand, authorization, direction, notice, consent, waiver or other Act
which this Indenture expressly provides may be made, given or taken by the
Holders of a specified percentage, which is less than a majority, in principal
amount of the Outstanding Securities of a series may be adopted at a meeting or
an adjourned meeting duly reconvened and at which a quorum is present as
aforesaid by the affirmative vote of the Holders of such specified percentage in
principal amount of the Outstanding Securities of such series.

         Any resolution passed or decision taken at any meeting of Holders of
Securities of any series duly held in accordance with this Section shall be
binding on all the Holders of Securities of such series and the Coupons
appertaining thereto, whether or not such Holders were present or represented at
the meeting.


         Section 1505.    Determination of Voting Rights; Conduct and
                          Adjournment of Meetings.

         (1) Notwithstanding any other provisions of this Indenture, the Trustee
may make such reasonable regulations as it may deem advisable for any meeting of
Holders of Securities of such series in regard to proof of the holding of
Securities of such series and of the appointment of proxies and in regard to the
appointment and duties of inspectors of votes, the submission and examination of
proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall deem appropriate.
Except as otherwise permitted or required by any such regulations, the holding
of Securities shall be proved in the manner specified in Section 104 and the
appointment of any proxy shall be proved in the manner specified in Section 104
or by having the signature of the person executing the proxy witnessed or
guaranteed by any trust company, bank or banker authorized by Section 104 to
certify to the holding of Bearer Securities. Such regulations may provide that
written instruments appointing proxies, regular on their face, may be presumed
valid and genuine without the proof specified in Section 104 or other proof.

         (2) The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders of Securities as provided in Section 1502(2), in which
case the Company or the Holders of Securities of the series calling the meeting,
as the case may be, shall in like manner appoint a temporary chairman. A
permanent chairman and a permanent secretary of the meeting shall be elected by
vote of the Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting.

         (3) At any meeting, each Holder of a Security of such series or proxy

                  this Indenture into Common Stock or other securities, if the
                  terms of such Security provide for such conversion or exchange
                  pursuant to Section 301;

provided, however, that in determining whether the Holders of the requisite
principal amount of Outstanding Securities have given any request, demand,
authorization, direction, notice, consent or waiver hereunder or are present at
a meeting of Holders of Securities for quorum purposes, (i) the principal amount
of an Original Issue Discount Security that may be counted in making such
determination and that shall be deemed to be Outstanding for such purposes shall
be equal to the amount of the principal thereof that pursuant to the terms of
such Original Issue Discount Security would be declared (or shall have been
declared to be) due and payable upon a declaration of acceleration thereof
pursuant to Section 502 at the time of such determination, and (ii) the
principal amount of any Indexed Security that may be counted in making such
determination and that shall be deemed outstanding for such purpose shall be
equal to the principal face amount of such Indexed Security at original
issuance, unless otherwise provided in or pursuant to this Indenture, and (iii)
the principal amount of a Security denominated in a Foreign Currency shall be
the Dollar equivalent, determined on the date of original issuance of such
Security, of the principal amount (or, in the case of an Original Issue Discount

Security of the amount determined as provided in (i) above) of such Security,
and (iv) Securities owned by the Company or any other obligor upon the
Securities or any Affiliate of the Company or such other obligor shall be
disregarded and deemed not to be Outstanding, except that, in determining
whether the Trustee shall be protected in making any such determination or
relying upon any such request, demand, authorization, direction, notice, consent
or waiver, only Securities which a Responsible Officer of the Trustee knows to
be so owned shall be so disregarded. Securities so owned which shall have been
pledged in good faith may be regarded as Outstanding if the pledgee establishes

respect to such Securities and (B) that the pledgee is not the Company or any
other obligor upon the Securities or an Affiliate of the Company or such other
obligor.

waiver or other action provided by or pursuant to this Indenture to be given 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 an agent duly
appointed in writing. Any request, demand, authorization, direction, notice,
consent, waiver or other action provided in or pursuant to this Indenture to be
given or taken by Holders of Securities of such series may, alternatively, be
embodied in and evidenced by the record of Holders of Securities of such series
voting in favor thereof, either in person or by proxies duly appointed in
writing, at any meeting of Holders of Securities of such series duly called and
held in accordance with the provisions of Article Fifteen, or a combination of
such instruments and any such record. Except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
or record or both are delivered to the Trustee and, where it is hereby expressly
required, to the Company. Such instrument or instruments and any such record
(and the action embodied therein and evidenced thereby) are herein sometimes
referred to as the "Act" of the Holders signing such instrument or instruments
or so voting at any such meeting. Proof of execution of any such instrument or
of a writing appointing any such agent, or of the holding by any Person of a
Security, shall be sufficient for any purpose of this Indenture and (subject to
Section 315 of the Trust Indenture Act) conclusive in favor of the Trustee and
the Company and any agent of the Trustee or the Company, if made in the manner
provided in this Section. The record of any meeting of Holders of Securities
shall be proved in the manner provided in Section 1506.

         Without limiting the generality of this Section 104, unless otherwise
provided in or pursuant to this Indenture, a Holder, including a U.S. Depository
that is a Holder of a global Security, may make, give or take, by a proxy, or
proxies, duly appointed in writing, any request, demand,


                                      12
<PAGE>
 
authorization, direction, notice, consent, waiver or other Act provided in or
pursuant to this Indenture or the Securities to be made, given or taken by
Holders, and a U.S. Depository that is a Holder of a global Security may provide
its proxy or proxies to the direct or indirect participants therein or the
beneficial owners of interests in any such global Security through such U.S.
Depository's standing instructions and customary practices.

         (2) The fact and date of the execution by any Person of any such
instrument or writing may be proved in any reasonable manner which the Trustee
deems sufficient and in accordance with such reasonable rules as the Trustee may
determine; and the Trustee may in any instance require further proof with
respect to any of the matters referred to in this Section.

         (3) The ownership, principal amount and serial numbers of Registered
Securities held by any Person, and the date of the commencement and the date of
the termination of holding the same, shall be proved by the Security Register.

         (4) The ownership, principal amount and serial numbers of Bearer
Securities held by any Person, and the date of the commencement and the date of
the termination of holding the same, may be proved by the production of such
Bearer Securities or by a certificate executed, as depositary, by any trust
company, bank, banker or other depositary reasonably acceptable to the Company,
wherever situated, if such certificate shall be deemed by the Company and the
Trustee to be satisfactory, showing that at the date therein mentioned such
Person had on deposit with such depositary, or exhibited to it, the Bearer
Securities therein described; or such facts may be proved by the certificate or
affidavit of the Person holding such Bearer Securities, if such certificate or
affidavit is deemed by the Company and the Trustee to be satisfactory. The
Trustee and the Company may assume that such ownership of any Bearer Security
continues until (1) another certificate or affidavit bearing a later date issued
in respect of the same Bearer Security is produced, or (2) such Bearer Security
is produced to the Trustee by some other Person, or (3) such Bearer Security is
surrendered in exchange for a Registered Security, or (4) such Bearer Security
is no longer Outstanding. The ownership, principal amount and serial numbers of
Bearer Securities held by the Person so executing such instrument or writing and
the date of the commencement and the date of the termination of holding the same
may also be proved in any other manner which the Company and the Trustee deem
sufficient.

         (5) If the Company shall solicit from the Holders of any Registered
Securities any request, demand, authorization, direction, notice, consent,
waiver or other Act, the Company may at its option (but is not obligated to), by
Board Resolution, fix in advance a record date for the determination of Holders
of Registered Securities entitled to give such request, demand, authorization,
direction, notice, consent, waiver or other Act. If such a record date is fixed,
such request, demand, authorization, direction, notice, consent, waiver or other
Act may be given before or after such record date, but only the Holders of
Registered Securities of record at the close of business on such record date
shall be deemed to be Holders for the purpose of determining whether Holders of
the requisite proportion of Outstanding Securities have authorized or agreed or
consented to such request, demand, authorization, direction, notice, consent,
waiver or other Act, and for that purpose the Outstanding Securities shall be
computed as of such record date; provided that no such


                                      13
<PAGE>
 
authorization, agreement or consent by the Holders of Registered Securities
shall be deemed effective unless it shall become effective pursuant to the
provisions of this Indenture not later than six months after the record date.

         (6) Any request, demand, authorization, direction, notice, consent,
waiver or other Act by 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 or suffered to be done by the Trustee, any Security
Registrar, any Paying Agent or the Company in reliance thereon, whether or not
notation of such Act is made upon such Security.


         Section 105.  Notices, Etc. to Trustee and Company.

         Any request, demand, authorization, direction, notice, consent, waiver
or other 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 the Company shall be
         sufficient for every purpose hereunder if made, given, furnished or
         filed in writing to or with the Trustee at its Corporate Trust Office,
         Attention: Corporate Trustee Administration Department, or

                  (2) the Company by the Trustee or 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 the attention of its Treasurer 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 the Trustee by the Company.


         Section 106.  Notice to Holders of Securities; Waiver.

         Except as otherwise expressly provided in or pursuant to this
Indenture, where this Indenture provides for notice to Holders of Securities of
any event,

                  (1) such notice shall be sufficiently given to Holders of
         Registered Securities if in writing and mailed, first-class postage
         prepaid, to each Holder of a Registered Security affected by such
         event, at his address as it appears in the Security Register, not later
         than the latest date, and not earlier than the earliest date,
         prescribed for the giving of such notice; and

                  (2) such notice shall be sufficiently given to Holders of
         Bearer Securities, if any, if published in an Authorized Newspaper in
         The City of New York and, if such Securities are then listed on any
         stock exchange outside the United States, in an Authorized Newspaper in
         such city as the Company shall advise the Trustee that such stock
         exchange so requires, on a Business Day at least twice, the first such
         publication to be not earlier than the earliest


                                      14
<PAGE>
 
         date and the second such publication not later than the latest date
         prescribed for the giving of such notice.

         In any case where notice to Holders of Registered Securities is given
by mail, neither the failure to mail such notice, nor any defect in any notice
so mailed, to any particular Holder of a Registered Security shall affect the
sufficiency of such notice with respect to other Holders of Registered
Securities or the sufficiency of any notice to Holders of Bearer Securities
given as provided herein. Any notice which is mailed in the manner herein
provided shall be conclusively presumed to have been duly given or provided. In
the 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 the Trustee shall constitute
a sufficient notification for every purpose hereunder.

         In case by reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearer Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder. Neither failure to give notice by
publication to Holders of Bearer Securities as provided above, nor any defect in
any notice so published, shall affect the sufficiency of any notice mailed to
Holders of Registered Securities as provided above.

         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 of Securities 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.


         Section 107.  Language of Notices.

         Any request, demand, authorization, direction, notice, consent,
election or waiver required or permitted under this Indenture shall be in the
English language, except that, if the Company so elects, any published notice
may be in an official language of the country of publication.


         Section 108.  Conflict with Trust Indenture Act.

         If any provision hereof limits, qualifies or conflicts with any duties
under any required provision of the Trust Indenture Act imposed hereon by
Section 318(c) thereof, such required provision shall control.

bind its successors and assigns, whether so expressed or not.


         Section 111.  Separability Clause.

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 112.  Benefits of Indenture.

         Nothing in this Indenture, any Security or any Coupon, express or
implied, shall give to any Person, other than the parties hereto, any Security
Registrar, any Paying Agent and their successors hereunder, the holders of
Senior Indebtedness and the Holders of Securities or Coupons, any benefit or any
legal or equitable right, remedy or claim under this Indenture.


         Section 113.  Governing Law.

         This Indenture, the Securities and any Coupons shall be governed by and
construed in accordance with the laws of the State of New York applicable to
agreements made or instruments entered into and, in each case, performed in said
State.


         Section 114.  Legal Holidays.

         Unless otherwise specified in or pursuant to this Indenture or any
Securities, in any case where any Interest Payment Date, Stated Maturity or
Maturity of any Security shall be a Legal Holiday at any Place of Payment, then
(notwithstanding any other provision of this Indenture, any Security or any
Coupon other than a provision in any Security or Coupon that specifically states
that such provision shall apply in lieu hereof) payment need not be made at such
Place of Payment on such date but such payment may be made on the next
succeeding day that is a Business Day at such Place of Payment with the same
force and effect as if made on the Interest Payment Date or at the Stated
Maturity or Maturity, and no interest shall accrue on the amount payable on such
date or at


                                      16
<PAGE>
 
such time for the period from and after such Interest Payment Date, Stated
Maturity or Maturity, as the case may be, to the next succeeding Business Day.

         This Indenture may be executed in several counterparts, each of which
shall be an original and all of which shall constitute but one and the same
instrument.


         Section 116.  Judgment Currency.

         The Company agrees, to the fullest extent that it may effectively do so
under applicable law, that (a) if for the purpose of obtaining judgment in any
court it is necessary to convert the sum due in respect of the principal of, or
premium or interest, if any, or Additional Amounts on the Securities of any
series (the "Required Currency") into a currency in which a judgment will be
rendered (the "Judgment Currency"), the rate of exchange used shall be the rate
at which in accordance with normal banking procedures the Trustee could purchase
in The City of New York the Required Currency with the Judgment Currency on the
New York Banking Day preceding that on which a final unappealable judgment is
given and (b) its obligations under this Indenture to make payments in the
Required Currency (i) shall not be discharged or satisfied by any tender, or any
recovery pursuant to any judgment (whether or not entered in accordance with
clause (a)), in any currency other than the Required Currency, except to the
extent that such tender or recovery shall result in the actual receipt, by the
payee, of the full amount of the Required Currency expressed to be payable in
respect of such payments, (ii) shall be enforceable as an alternative or
additional cause of action for the purpose of recovering in the Required
Currency the amount, if any, by which such actual receipt shall fall short of
the full amount of the Required Currency so expressed to be payable and (iii)
shall not be affected by judgment being obtained for any other sum due under
this Indenture. For purposes of the foregoing, "New York Banking Day" means any
day except a Saturday, Sunday or a legal holiday in The City of New York or a

         Unless otherwise provided in or pursuant to this Indenture or any
Securities, the Securities shall not be issuable in global form. If Securities
of a series shall be issuable in temporary or permanent global form, any such
Security may provide that it or any number of such Securities shall represent
the aggregate amount of all Outstanding Securities of such series (or such
lesser amount as is permitted by the terms thereof) from time to time endorsed
thereon and may also provide that the aggregate amount of Outstanding Securities
represented thereby may from time to time be increased or reduced to reflect
exchanges. Any endorsement of any Security in global form to reflect the amount,
or any increase or decrease in the amount, or changes in the rights of Holders,
of Outstanding Securities represented thereby shall be made in such manner and
by such Person or Persons as shall be specified therein or in the Company Order
to be delivered pursuant to Section 303 or 304 with respect thereto. Subject to

applicable Company Order. If a Company Order pursuant to Section 303 or 304 has
been, or simultaneously is, delivered, any instructions by the Company with
respect to a Security in global form shall be in writing but need not be
accompanied by or contained in an Officers' Certificate and need not be
accompanied by an Opinion of Counsel.

         Notwithstanding the provisions of Section 307, unless otherwise
specified in or pursuant to this Indenture or any Securities, payment of
principal of, any premium and interest on, and any Additional Amounts in respect

the preceding paragraph, the Company, the Trustee and any agent of the Company
and the Trustee shall treat as the Holder of such principal amount of
Outstanding Securities represented by a global Security (i) in the case of a
global Security in registered form, the Holder of such global Security in
registered form, or (ii) in the case of a global Security in bearer form, the
Person or Persons specified pursuant to Section 301.

to Bearer Securities of such series shall be substantially identical except as
to Currency of payments due thereunder, denomination and the rate of interest,
or method of determining the rate of interest, if any, Maturity, and the date

provided by the Company in or pursuant to the Board Resolution and set forth in,
or determined in the manner provided in, the Officers' Certificate or in any
indenture or indentures supplemental hereto pertaining to such series of
Securities. The terms of the Securities of any series may provide, without
limitation, that the Securities shall be authenticated and delivered by the
Trustee on original issue from time to time upon telephonic or written order of
persons designated in the Officers' Certificate or supplemental indenture
(telephonic instructions to be promptly confirmed in writing by such person) and
that such persons are authorized to determine, consistent with such Officers'
Certificate or any applicable supplemental indenture, such terms and conditions
of the Securities of such series as are specified in such Officers' Certificate
or supplemental indenture. All Securities of any one series need not be issued
at the same time and, unless otherwise so provided by the Company, a series may
be reopened for issuances of additional Securities of such series or to
establish additional terms of such series of Securities.

         If any of the terms of the Securities of any series shall be
established by action taken by or pursuant to a Board Resolution, the Board
Resolution shall be delivered to the Trustee at or prior to the delivery of the

shall be issuable in registered form without Coupons in denominations of $1,000
and any integral multiple thereof, and the Bearer Securities denominated in
Dollars shall be issuable in the denomination of $5,000. Securities not

         Section 303. Execution, Authentication, Delivery and Dating.

         Securities shall be executed on behalf of the Company by any Officer
under its corporate seal reproduced thereon and attested by its Corporate
Secretary (provided that the Corporate Secretary shall not attest his or her own
signature as an Officer) or one of its Assistant Corporate Secretaries. Coupons
shall be executed on behalf of the Company by the Corporate Secretary or one of
the Assistant Corporate Secretaries of the Company. The signature of any of
these officers on the Securities or any Coupons appertaining thereto may be
manual or facsimile.

                                      23
<PAGE>
 
         Securities and any Coupons appertaining thereto 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 or Coupons.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities, together with any Coupons
appertaining thereto, executed by the Company, to the Trustee for authentication
and, provided that the Board Resolution and Officers' Certificate or
supplemental indenture or indentures with respect to such Securities referred to
in Section 301 and a Company Order for the authentication and delivery of such
Securities have been delivered to the Trustee, the Trustee in accordance with
the Company Order and subject to the provisions hereof and of such Securities
shall authenticate and deliver such Securities. In authenticating such
Securities, and accepting the additional responsibilities under this Indenture
in relation to such Securities and any Coupons appertaining thereto, the Trustee
shall be entitled to receive, and (subject to Sections 315(a) through 315(d) of
the Trust Indenture Act) shall be fully protected in relying upon,

                  (1)  an Opinion of Counsel to the effect that:

                       (a) the form or forms and terms , or if all
                  Securities of such series are not to be issued at one time,
                  the manner of determining the terms of such Securities and
                  Coupons, if any, have been established in conformity with the
                  provisions of this Indenture;

                       (b) all conditions precedent provided for in this
                  Indenture to the authentication and delivery of such
                  Securities and Coupons, if any, appertaining thereto have been
                  complied with and that such Securities, and Coupons, when
                  completed by appropriate insertions, executed under the
                  Company's corporate seal and attested by duly authorized
                  officers of the Company, delivered by duly authorized officers
                  of the Company to the Trustee for authentication pursuant to
                  this Indenture, and 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 binding obligations of the Company,
                  enforceable against the Company in accordance with their
                  terms, except as enforcement thereof may be subject to or
                  limited by bankruptcy, insolvency, reorganization, moratorium,
                  arrangement, fraudulent conveyance, fraudulent transfer or
                  other similar laws relating to or affecting creditors' rights
                  generally, and subject to general principles of equity
                  (regardless of whether enforcement is sought in a proceeding
                  in equity or at law); and

                       (c) this Indenture has been qualified under the
                  Trust Indenture Act;

         and

                                      24
<PAGE>
 
                  (2) an Officers' Certificate stating that, to the best
         knowledge of the Persons executing such certificate, no event which is,
         or after notice or lapse of time would become, an Event of Default with
         respect to any of the Securities shall have occurred and be continuing.

         If all the Securities of any series are not to be issued at one time,
it shall not be necessary to deliver an Opinion of Counsel at the time of
issuance of each Security, but such opinion shall be delivered at or before the
time of issuance of the first Security of such series. After any such first
delivery, any separate request by the Company that the Trustee authenticate
Securities of such series for original issue will be deemed to be a
certification by the Company that all conditions precedent provided for in this
Indenture relating to authentication and delivery of such Securities continue to
have been complied with.

         The Trustee shall not be required to authenticate or to cause an
Authenticating Agent to authenticate any 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 or if the Trustee,
being advised by counsel, determines that such action may not lawfully be taken.

          Each Registered Security shall be dated the date of its
authentication. Each Bearer Security and any Bearer Security in global form
shall be dated as of the date specified in or pursuant to this Indenture. No
Security or Coupon appertaining thereto 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 in Section 202 or 611 executed by or on behalf of the Trustee or by
the Authenticating Agent by the manual signature of one of its authorized
officers. Such certificate upon any Security shall be conclusive evidence, and
the only evidence, that such Security has been duly authenticated and delivered
hereunder. Except as permitted by Section 306 or 307, the Trustee shall not
authenticate and deliver any Bearer Security unless all Coupons appertaining
thereto then matured have been detached and cancelled.


         Section 304. Temporary Securities.

         Pending the preparation of definitive Securities, the Company may
execute and deliver to the Trustee and, upon Company Order, the Trustee shall
authenticate and deliver, in the manner provided in Section 303, temporary
Securities in lieu thereof 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, in registered form or, if authorized in or pursuant to this
Indenture, in bearer form with one or more Coupons or without Coupons and with
such appropriate insertions, omissions, substitutions and other variations as
the officers of the Company executing such Securities may determine, as
conclusively evidenced by their execution of such Securities. Such temporary
Securities may be in global form.

                                      25
<PAGE>
 
         Except in the case of temporary Securities in global form, which shall
be exchanged in accordance with the provisions thereof, if temporary Securities
are issued, the Company shall cause definitive Securities to be prepared without
unreasonable delay. After the preparation of definitive Securities of the same
series and containing terms and provisions that are identical to those of any
temporary Securities, such temporary Securities shall be exchangeable for such
definitive Securities upon surrender of such temporary Securities at an Office
or Agency for such Securities, without charge to any Holder thereof. Upon
surrender for cancellation of any one or more temporary Securities (accompanied
by any unmatured Coupons appertaining thereto), the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of authorized denominations of the same series
and containing identical terms and provisions; provided, however, that no
definitive Bearer Security, except as provided in or pursuant to this Indenture,
shall be delivered in exchange for a temporary Registered Security; and
provided, further, that a definitive Bearer Security shall be delivered in
exchange for a temporary Bearer Security only in compliance with the conditions
set forth in or pursuant to this Indenture. Unless otherwise provided in or
pursuant to this Indenture with respect to a temporary global Security, 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.


         Section 305. Registration, Transfer and Exchange.

         With respect to the Registered Securities of each series, if any, the
Company shall cause to be kept a register (each such register being herein
sometimes referred to as the "Security Register") at an Office or Agency for
such series in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of the Registered
Securities of such series and of transfers of the Registered Securities of such
series. Such Office or Agency shall be the "Security Registrar" for that series
of Securities. Unless otherwise specified in or pursuant to this Indenture or
the Securities, the Trustee shall be the initial Security Registrar for each
series of Securities. The Company shall have the right to remove and replace
from time to time the Security Registrar for any series of Securities; provided
that no such removal or replacement shall be effective until a successor
Security Registrar with respect to such series of Securities shall have been
appointed by the Company and shall have accepted such appointment. In the event
that the Trustee shall not be or shall cease to be Security Registrar with
respect to a series of Securities, it shall have the right to examine the
Security Register for such series at all reasonable times. There shall be only
one Security Register for each series of Securities.

         Upon surrender for registration of transfer of any Registered Security
of any series at any Office or Agency for such series, the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Registered Securities of
the same series denominated as authorized in or pursuant to this Indenture, of a
like aggregate principal amount bearing a number not contemporaneously
outstanding and containing identical terms and provisions.

                                      26
<PAGE>
 
         At the option of the Holder, Registered Securities of any series may be
exchanged for other Registered Securities of the same series containing
identical terms and provisions, in any authorized denominations, and of a like
aggregate principal amount, upon surrender of the Securities to be exchanged at
any Office or Agency for such series. Whenever any Registered Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Registered Securities which the Holder making the
exchange is entitled to receive.

         If provided in or pursuant to this Indenture, with respect to
Securities of any series, at the option of the Holder, Bearer Securities of such
series may be exchanged for Registered Securities of such series containing
identical terms, denominated as authorized in or pursuant to this Indenture and
in the same aggregate principal amount, upon surrender of the Bearer Securities
to be exchanged at any Office or Agency for such series, with all unmatured
Coupons and all matured Coupons in default thereto appertaining. If the Holder
of a Bearer Security is unable to produce any such unmatured Coupon or Coupons
or matured Coupon or Coupons in default, such exchange may be effected if the
Bearer Securities are accompanied by payment in funds acceptable to the Company
and the Trustee in an amount equal to the face amount of such missing Coupon or
Coupons, or the surrender of such missing Coupon or Coupons may be waived by the
Company and the Trustee if there is furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless. If
thereafter the Holder of such Bearer Security shall surrender to any Paying
Agent any such missing Coupon in respect of which such a payment shall have been
made, such Holder shall be entitled to receive the amount of such payment;
provided, however, that, except as otherwise provided in Section 1002, interest
represented by Coupons shall be payable only upon presentation and surrender of
those Coupons at an Office or Agency for such series located outside the United
States. Notwithstanding the foregoing, in case a Bearer Security of any series
is surrendered at any such Office or Agency for such series in exchange for a
Registered Security of such series and like tenor after the close of business at
such Office or Agency on (i) any Regular Record Date and before the opening of
business at such Office or Agency on the relevant Interest Payment Date, or (ii)
any Special Record Date and before the opening of business at such Office or
Agency on the related date for payment of Defaulted Interest, such Bearer
Security shall be surrendered without the Coupon relating to such Interest
Payment Date or proposed date of payment, as the case may be (or, if such Coupon
is so surrendered with such Bearer Security, such Coupon shall be returned to
the Person so surrendering the Bearer Security), and interest or Defaulted
Interest, as the case may be, shall not be payable on such Interest Payment Date
or proposed date for payment, as the case may be, in respect of the Registered
Security issued in exchange for such Bearer Security, but shall be payable only
to the Holder of such Coupon when due in accordance with the provisions of this
Indenture.

         If provided in or pursuant to this Indenture with respect to Securities
of any series, at the option of the Holder, Registered Securities of such series
may be exchanged for Bearer Securities upon such terms and conditions as may be
provided in or pursuant to this Indenture with respect to such series.

                                      27
<PAGE>
 
         Whenever any Securities are surrendered for exchange as contemplated by
the immediately preceding two paragraphs, the Company shall execute, and the
Trustee shall authenticate and deliver, the Securities which the Holder making
the exchange is entitled to receive.

         Notwithstanding the foregoing, except as otherwise provided in or
pursuant to this Indenture, any global Security shall be exchangeable for
definitive Securities only if (i) the Depository is at any time unwilling,
unable or ineligible to continue as Depository and a successor depository is not
appointed by the Company within 90 days of the date the Company is so informed
in writing, (ii) the Company executes and delivers to the Trustee a Company
Order to the effect that such global Security shall be so exchangeable, or (iii)
an Event of Default has occurred and is continuing with respect to the
Securities. If the beneficial owners of interests in a global Security are
entitled to exchange such interests for definitive Securities as the result of
an event described in clause (i), (ii) or (iii) of the preceding sentence, then
without unnecessary delay but in any event not later than the earliest date on
which such interests may be so exchanged, the Company shall deliver to the
Trustee definitive Securities in such form and denominations as are required by
or pursuant to this Indenture, and of the same series, containing identical
terms and in aggregate principal amount equal to the principal amount of such
global Security, executed by the Company. On or after the earliest date on which
such interests may be so exchanged, such global Security shall be surrendered
from time to time by the U.S. Depository or such other Depository as shall be
specified in the Company Order with respect thereto, and in accordance with
instructions given to the Trustee and the U.S. Depository or such other
Depository, as the case may be (which instructions shall be in writing but need
not be contained in or accompanied by an Officers' Certificate or be accompanied
by an Opinion of Counsel), as shall be specified in the Company Order with
respect thereto to the Trustee, as the Company's agent for such purpose, to be
exchanged, in whole or in part, for definitive Securities as described above
without charge. The Trustee shall authenticate and make available for delivery,
in exchange for each portion of such surrendered global Security, a like
aggregate principal amount of definitive Securities of the same series of
authorized denominations and of like tenor as the portion of such global
Security to be exchanged, which (unless such Securities are not issuable both as
Bearer Securities and as Registered Securities, in which case the definitive
Securities exchanged for the global Security shall be issuable only in the form
in which the Securities are issuable, as provided in or pursuant to this
Indenture) shall be in the form of Bearer Securities or Registered Securities,
or any combination thereof, as shall be specified by the beneficial owner
thereof, but subject to the satisfaction of any certification or other
requirements to the issuance of Bearer Securities; provided, however, that no
such exchanges may occur during a period beginning at the opening of business 15
days before any selection of Securities of the same series to be redeemed and
ending on the relevant Redemption Date; and provided, further, that (unless
otherwise provided in or pursuant to this Indenture) no Bearer Security
delivered in exchange for a portion of a global Security shall be mailed or
otherwise delivered to any location in the United States. Promptly following any
such exchange in part, such global Security shall be returned by the Trustee to
such Depository or the U.S. Depository, as the case may be, or such other
Depository or U.S. Depository referred to above in accordance with the
instructions of the Company referred to above. If a Registered Security is
issued in exchange for any portion of a global Security after the close of
business at the Office or Agency for such Security where such exchange occurs on
or after (i) any Regular Record Date for such Security and before the opening of
business at such

                                      28
<PAGE>
 
Office or Agency on the next Interest Payment Date, or (ii) any Special Record
Date for such Security and before the opening of business at such Office or
Agency on the related proposed date for payment of interest or Defaulted
Interest, as the case may be, interest shall not be payable on such Interest
Payment Date or proposed date for payment, as the case may be, in respect of
such Registered Security, but shall be payable on such Interest Payment Date or
proposed date for payment, as the case may be, only to the Person to whom
interest in respect of such portion of such global Security shall be payable in
accordance with the provisions of this Indenture.

         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 entitling the Holders thereof to the same benefits under this Indenture
as the Securities surrendered upon such registration of transfer or exchange.

         Every Registered Security presented or surrendered for registration of
transfer or for exchange or redemption shall (if so required by the Company or
the Security Registrar for such Security) be duly endorsed, or be accompanied by
a written instrument of transfer in form satisfactory to the Company and the
Security Registrar for such Security 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, or redemption of Securities, but the Company may require payment of a
sum sufficient to cover any tax or other governmental charge and any other
expenses (including fees and expenses of the Trustee) that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 304, 905 or 1107, upon repayment in part of
any Registered Security pursuant to Article Thirteen, or upon surrender in part
of any Registered Security for conversion or exchange into Common Stock or other
securities pursuant to its terms, in each case not involving any transfer.

         Except as otherwise provided in or pursuant to this Indenture, the
Company shall not be required (i) to issue, register the transfer of or exchange
any Securities during a period beginning at the opening of business 15 days
before the day of the selection for redemption of Securities of like tenor and
the same series under Section 1103 and ending at the close of business on the
day of such selection, or (ii) to register the transfer of or exchange any
Registered Security so selected for redemption in whole or in part, except in
the case of any Security to be redeemed in part, the portion thereof not to be
redeemed, or (iii) to exchange any Bearer Security so selected for redemption
except, to the extent provided with respect to such Bearer Security, that such
Bearer Security may be exchanged for a Registered Security of like tenor and the
same series, provided that such Registered Security shall be immediately
surrendered for redemption with written instruction for payment consistent with
the provisions of this Indenture or (iv) to issue, register the transfer of or
exchange any Security which, in accordance with its terms, has been surrendered
for repayment at the option of the Holder, except the portion, if any, of such
Security not to be so repaid.

         Section 306. Mutilated, Destroyed, Lost and Stolen Securities.

         If any mutilated Security or a Security with a mutilated Coupon
appertaining to it is surrendered to the Trustee, subject to the provisions of
this Section 306, the Company shall execute and the Trustee shall authenticate
and deliver in exchange therefor a new Security of the same series containing
identical terms and of like principal amount and bearing a number not
contemporaneously outstanding, with Coupons appertaining thereto corresponding
to the Coupons, if any, appertaining to the surrendered Security.

         If there be delivered to the Company and to the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security or Coupon,
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 or Coupon has been acquired by a
bona fide purchaser, the Company shall execute and, upon the Company's request
the Trustee shall authenticate and deliver, in exchange for or in lieu of any
such mutilated, destroyed, lost or stolen Security or in exchange for the
Security to which a destroyed, lost or stolen Coupon appertains with all
appurtenant Coupons not destroyed, lost or stolen, a new Security of the same
series containing identical terms and of like principal amount and bearing a
number not contemporaneously outstanding, with Coupons corresponding to the
Coupons, if any, appertaining to such destroyed, lost or stolen Security or to
the Security to which such destroyed, lost or stolen Coupon appertains.

         Notwithstanding the foregoing provisions of this Section 306, in case
any mutilated, destroyed, lost or stolen Security or Coupon 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 or Coupon; provided, however, that
payment of principal of, any premium or interest on or any Additional Amounts
with respect to any Bearer Securities shall, except as otherwise provided in
Section 1002, be payable only at an Office or Agency for such Securities located
outside the United States and, unless otherwise provided in or pursuant to this
Indenture (including this paragraph), any interest on Bearer Securities and any
Additional Amounts with respect to such interest shall be payable only upon
presentation and surrender of the Coupons appertaining thereto.

         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, with any Coupons appertaining thereto issued
pursuant to this Section in lieu of any destroyed, lost or stolen Security, or
in exchange for a Security to which a destroyed, lost or stolen Coupon
appertains shall constitute a separate obligation of the Company, whether or not
the destroyed, lost or stolen Security and Coupons appertaining thereto or the
destroyed, lost or stolen Coupon 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 such series and any
Coupons, if any, duly issued hereunder.

         The provisions of this Section, as amended or supplemented pursuant to
this Indenture with respect to particular Securities or generally, shall be
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 or Coupons.


         Section 307. Payment of Interest and Certain Additional Amounts; Rights
                      to Interest and Certain Additional Amounts Preserved.

         Unless otherwise provided in or pursuant to this Indenture, any
interest on and any Additional Amounts with respect to any Registered Security
which shall be payable, and are punctually paid or duly provided for, on any
Interest Payment Date shall be paid to the Person in whose name such Security
(or one or more Predecessor Securities) is registered as of the close of
business on the Regular Record Date for such interest. Unless otherwise provided
in or pursuant to this Indenture, in case a Bearer Security is surrendered in
exchange for a Registered Security after the close of business at an Office or
Agency for such Security on any Regular Record Date therefor and before the
opening of business at such Office or Agency on the next succeeding Interest
Payment Date therefor, such Bearer Security shall be surrendered without the
Coupon relating to such Interest Payment Date and interest shall not be payable
on such Interest Payment Date in respect of the Registered Security issued in
exchange for such Bearer Security, but shall be payable only to the Holder of
such Coupon when due in accordance with the provisions of this Indenture.

         Unless otherwise provided in or pursuant to this Indenture, any
interest on and any Additional Amounts with respect to any Registered Security
which shall be payable, but shall not be punctually paid or duly provided for,
on any Interest Payment Date for such Registered Security (herein called
"Defaulted Interest") shall forthwith cease to be payable to the Holder thereof
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 Person in whose name such Registered Security (or a
         Predecessor Security thereof) shall be 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 such Registered Security 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 on or prior
         to the date of the proposed payment, such money when so deposited to be
         held in trust for the benefit of the Person 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

                                      31
<PAGE>
 
         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 the Holder of such Registered
         Security (or a Predecessor Security thereof) at his address as it
         appears in the Security Register not less than 10 days prior to such
         Special Record Date. The Trustee may, in its discretion, in the name
         and at the expense of the Company cause a similar notice to be
         published at least once in an Authorized Newspaper of general
         circulation in the Borough of Manhattan, The City of New York, but such
         publication shall not be a condition precedent to the establishment of
         such Special Record Date. Notice of the proposed payment of such
         Defaulted Interest and the Special Record Date therefor having been
         mailed as aforesaid, such Defaulted Interest shall be paid to the
         Person in whose name such Registered Security (or a Predecessor
         Security thereof) shall be registered at the close of business on such
         Special Record Date and shall no longer be payable pursuant to the
         following clause (2). In case a Bearer Security is surrendered at the
         Office or Agency for such Security in exchange for a Registered
         Security after the close of business at such Office or Agency on any
         Special Record Date and before the opening of business at such Office
         or Agency on the related proposed date for payment of Defaulted
         Interest, such Bearer Security shall be surrendered without the Coupon
         relating to such Defaulted Interest and Defaulted Interest shall not be
         payable on such proposed date of payment in respect of the Registered
         Security issued in exchange for such Bearer Security, but shall be
         payable only to the Holder of such Coupon when due in accordance with
         the provisions of this Indenture.

                  (2) The Company may make payment of any Defaulted Interest in
         any other lawful manner not inconsistent with the requirements of any
         securities exchange on which such Security 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 payment shall be deemed practicable by the Trustee.

         Unless otherwise provided in or pursuant to this Indenture or the
Securities of any particular series, at the option of the Company, interest on
Registered Securities that bear interest may be paid by mailing a check to the
address of the Person entitled thereto as such address shall appear in the
Security Register or by transfer to an account maintained by the payee with a
bank located in the United States , provided that appropriate wire transfer
instructions shall have been delivered by such payee to the Paying Agent at
least five Business Days prior to the applicable date for payment of interest.

         Subject to the foregoing provisions of this Section and Section 305,
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 Registered 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 Registered Security is registered in the
Security Register as the owner of such Registered Security for the purpose of
receiving payment of principal of, any premium and (subject to Sections 305 and
307) interest on and any Additional Amounts with respect to such Registered
Security and for all other purposes whatsoever, whether or not any payment with
respect to such Registered Security shall be overdue, and neither the Company,
the Trustee or any agent of the Company or the Trustee shall be affected by
notice to the contrary.

         The Company, the Trustee and any agent of the Company or the Trustee
may treat the bearer of any Bearer Security or the bearer of any Coupon as the
absolute owner of such Security or Coupon for the purpose of receiving payment
thereof or on account thereof and for all other purposes whatsoever, whether or
not any payment with respect to such Security or Coupon shall be overdue, and
neither the Company, the Trustee or any agent of the Company or the Trustee
shall be affected by notice to the contrary.

         No holder of any beneficial interest in any global Security held on its
behalf by a U.S. Depository or Depository shall have any rights under this
Indenture with respect to such global Security, and such U.S. Depository or
Depository may be treated by the Company, the Trustee, and any agent of the
Company or the Trustee as the owner of such global Security for all purposes
whatsoever. None of the Company, the Trustee, any Paying Agent or the Security
Registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of a global Security or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.


         Section 309. Cancellation.

         All Securities and Coupons surrendered for payment, redemption,
registration of transfer, exchange or conversion or for credit against any
sinking fund payment shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee, and any such Securities and Coupons, as well as
Securities and Coupons surrendered directly to the Trustee for any such purpose,
shall be cancelled promptly by the Trustee. 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 all Securities so delivered shall be cancelled promptly 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 or pursuant to this Indenture. All cancelled Securities and Coupons held by
the Trustee shall be disposed of by the Trustee in accordance with its customary
procedures, unless by a Company Order the Company directs their return to it.

         Section 310. Computation of Interest.

         Except as otherwise provided in or pursuant to this Indenture or in the
Securities of any series, interest on the Securities shall be computed on the
basis of a 360-day year of twelve 30-day months.


         Section 311. CUSIP, CINS or ISIN Numbers.

         The Company in issuing the Securities may use "CUSIP", "CINS" or "ISIN"
numbers (if then generally in use), and, if so, the Trustee or the Company shall
use "CUSIP", "CINS" or "ISIN" numbers in notices of redemption or repurchase 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 or repurchase
and that reliance may be placed only on the other identification numbers printed
on the Securities, and any such redemption or repurchase shall not be affected
by any defect in or omission of such numbers.


                                  ARTICLE FOUR

                     SATISFACTION AND DISCHARGE OF INDENTURE


         Section 401. Satisfaction and Discharge.

         Upon the direction of the Company by a Company Order, this Indenture
shall cease to be of further effect with respect to any series of Securities
specified in such Company Order and any Coupons appertaining thereto, and the
Trustee, on receipt of a Company Order, at the expense of the Company, shall
execute proper instruments acknowledging satisfaction and discharge of this
Indenture as to such series, when

                  (1)   either

                        (a) all Securities of such series theretofore
                  authenticated and delivered and all Coupons appertaining
                  thereto (other than (i) Coupons appertaining to Bearer
                  Securities of such series surrendered in exchange for
                  Registered Securities of such series and maturing after such
                  exchange whose surrender is not required or has been waived as
                  provided in Section 305, (ii) Securities and Coupons of such
                  series which have been destroyed, lost or stolen and which
                  have been replaced or paid as provided in Section 306, (iii)
                  Coupons appertaining to Securities of such series called for

                  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 of such series and, in the case
                  of (i) or (ii) below, any Coupons appertaining thereto 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) if redeemable at the option of the Company,
                        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 (i), (ii) or (iii) above, has
                  deposited or caused to be deposited with the Trustee as trust
                  funds in trust for such purpose, money in the Currency in
                  which such Securities are payable in an amount sufficient to
                  pay and discharge the entire indebtedness on such Securities
                  and any Coupons appertaining thereto not theretofore delivered
                  to the Trustee for cancellation, including the principal of,
                  any premium and interest on, and, to the extent that the
                  Securities of such series provide for the payment of
                  Additional Amounts thereon and the amount of any such
                  Additional Amounts is at the time of deposit reasonably
                  determinable by the Company (in the exercise by the Company of
                  its sole and absolute discretion), any Additional Amounts with
                  respect to, such Securities and any Coupons appertaining
                  thereto, to the date of such deposit (in the case of
                  Securities which have become due and payable) or to the
                  Maturity thereof, as the case may be;

                  (2) the Company has paid or caused to be paid all other sums
         payable hereunder by the Company with respect to the Outstanding
         Securities of such series and any Coupons appertaining thereto; 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 as to such series have been complied with.

         In the event there are Securities of two or more series hereunder, the
Trustee shall be required to execute an instrument acknowledging satisfaction
and discharge of this Indenture only if requested to do so with respect to
Securities of such series as to which it is Trustee and if the other conditions
thereto are met.

                                      35
<PAGE>
 
         Notwithstanding the satisfaction and discharge of this Indenture with
respect to any series of Securities, the obligations of the Company to the
Trustee under Section 606 and, if money shall have been deposited with the
Trustee pursuant to subclause (b) of clause (1) of this Section, the obligations
of the Company and the Trustee with respect to the Securities of such series
under Sections 305, 306, 403, 1002 and 1003, with respect to the payment of
Additional Amounts, if any, with respect to such Securities as contemplated by
Section 1004 (but only to the extent that the Additional Amounts payable with
respect to such Securities exceed the amount deposited in respect of such
Additional Amounts pursuant to Section 401(1)(b)), and with respect to any
rights to convert or exchange such Securities into Common Stock or other
securities, shall survive.

         Section 402. Defeasance and Covenant Defeasance.

         (1) Unless, pursuant to Section 301, either or both of (i) defeasance
of the Securities of or within a series under clause (2) of this Section 402 or
(ii) covenant defeasance of the Securities of or within a series under clause
(3) of this Section 402 shall not be applicable with respect to the Securities
of such series, then such provisions, together with the other provisions of this
Section 402 (with such modifications thereto as may be specified pursuant to
Section 301 with respect to any Securities), shall be applicable to such
Securities and any Coupons appertaining thereto, and the Company may at its
option by Board Resolution, at any time, with respect to such Securities and any
Coupons appertaining thereto, elect to have Section 402(2) or Section 402(3) be
applied to such Outstanding Securities and any Coupons appertaining thereto upon
compliance with the conditions set forth below in this Section 402.

         (2) Upon the Company's exercise of the above option applicable to this
Section 402(2) with respect to any Securities of or within a series, the Company
shall be deemed to have been discharged from its obligations with respect to
such Outstanding Securities and any Coupons appertaining thereto on the date the
conditions set forth in clause (4) of this Section 402 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 such Outstanding Securities and any Coupons appertaining thereto,
which shall thereafter be deemed to be "Outstanding" only for the purposes of
clause (5) of this Section 402 and the other Sections of this Indenture referred
to in clauses (i) and (ii) below, and to have satisfied all of its other
obligations under such Securities and any Coupons appertaining thereto and this
Indenture insofar as such Securities and any Coupons appertaining thereto 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: (i) the rights of
Holders of such Outstanding Securities and any Coupons appertaining thereto to
receive, solely from the trust fund described in clause (4) of this Section 402
and as more fully set forth in such Section, payments in respect of the
principal of (and premium, if any) and interest, if any, on, and Additional
Amounts, if any, with respect to, such Securities and any Coupons appertaining
thereto when such payments are due, and any rights of such Holder to convert or
exchange such Securities into Common Stock or other securities, (ii) the
obligations of the Company and the Trustee with respect to such Securities under
Sections 305, 306, 1002 and 1003, with respect to the payment of Additional
Amounts, if any, on such Securities as contemplated by Section 1004 (but only to
the extent that the

                                      36
<PAGE>
 
Additional Amounts payable with respect to such Securities exceed the amount
deposited in respect of such Additional Amounts pursuant to Section 401(4)(a)
below), and with respect to any rights to convert or exchange such Securities
into Common Stock or other securities, (iii) the rights, powers, trusts, duties
and immunities of the Trustee hereunder (including under Section 606) and (iv)
this Section 402. The Company may exercise its option under this Section 402(2)
notwithstanding the prior exercise of its option under clause (3) of this
Section 402 with respect to such Securities and any Coupons appertaining
thereto.

     (3)   Upon the Company's exercise of the above option applicable to this
Section 402(3) with respect to any Securities of or within a series, the Company
shall be released from any covenant applicable to such Securities specified
pursuant to Section 301(19), with respect to such Outstanding Securities and any
Coupons appertaining thereto on and after the date the conditions set forth in
clause (4) of this Section 402 are satisfied (hereinafter, "covenant
defeasance"), and such Securities and any Coupons appertaining thereto shall
thereafter be deemed to be not "Outstanding" for the purposes of any direction,
waiver, consent or declaration or Act of Holders (and the consequences of any
thereof) in connection with any such covenant, but shall continue to be deemed
"Outstanding" for all other purposes hereunder. For this purpose, such covenant
defeasance means that, with respect to such Outstanding Securities and any
Coupons appertaining thereto, 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 covenant, whether directly or indirectly, by reason of any reference
elsewhere herein to any such other covenant or by reason of reference in any
such covenant to any other provision herein or in any other document and such
omission to comply shall not constitute a default or an Event of Default under
Section 501(4) or 501(7) or otherwise, as the case may be, but, except as
specified above, the remainder of this Indenture and such Securities and Coupons
appertaining thereto shall be unaffected thereby.

     (4)   The following shall be the conditions to application of clause (2) or
(3) of this Section 402 to any Outstanding Securities of or within a series and
any Coupons appertaining thereto:

           (a)     The Company shall irrevocably have deposited or caused to be
     deposited with the Trustee (or another trustee satisfying the requirements
     of Section 607 who shall agree to comply with the provisions of this
     Section 402 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 and any
     Coupons appertaining thereto, (1) an amount in Dollars or in such Foreign
     Currency in which such Securities and any Coupons appertaining thereto are
     then specified as payable at Stated Maturity, or (2) Government Obligations
     applicable to such Securities and Coupons appertaining thereto (determined
     on the basis of the Currency in which such Securities and Coupons
     appertaining thereto are then specified as payable at Stated Maturity)
     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 of principal of (and premium, if any)
     and interest, if any, on such Securities and any Coupons appertaining
     thereto, money in an amount, or (3) a combination thereof, in any case, in
     an amount, sufficient, without consideration of any reinvestment of such
     principal and interest,

                                      37
<PAGE>
 
     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, (y) the principal of
     (and premium, if any) and interest, if any, on, and, to the extent that
     such Securities provide for the payment of Additional Amounts thereon and
     the amount of any such Additional Amounts is at the time of deposit
     reasonably determinable by the Company (in the exercise by the Company of
     its sole and absolute discretion), any Additional Amounts with respect to,
     such Outstanding Securities and any Coupons appertaining thereto to and
     including the Stated Maturity of such principal or installment of principal
     or interest or the Redemption Date established pursuant to clause (e) below
     and (z) any mandatory sinking fund payments or analogous payments
     applicable to such Outstanding Securities and any Coupons appertaining
     thereto on the day on which such payments are due and payable in accordance
     with the terms of this Indenture and of such Securities and any Coupons
     appertaining thereto.

           (b)     Such defeasance or covenant defeasance shall not result in a
     breach or violation of, or constitute a default under, this Indenture or
     any other material agreement or instrument to which the Company is a party
     or by which it is bound.

           (c)     Solely in the case of an election under clause (2) of this
     Section 402, no Event of Default or event which with notice or lapse of
     time or both would become an Event of Default with respect to such
     Securities and any Coupons appertaining thereto shall have occurred and be
     continuing on the date of such deposit or at any time during the period
     ending on the 91st day after the date of such deposit (it being understood
     that this condition shall not be deemed satisfied until the expiration of
     such period).

           (d)     In the case of an election under clause (2) of this Section
     402, the Company shall have delivered to the Trustee an Opinion of Counsel
     stating that (i) the Company has received from the Internal Revenue Service
     a letter ruling, or there has been published by the Internal Revenue
     Service a Revenue Ruling, or (ii) since the date of execution of this
     Indenture, there has been a change in the applicable Federal income tax
     law, in either case to the effect that, and based thereon such opinion
     shall confirm that, the Holders of such Outstanding Securities and any
     Coupons appertaining thereto 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.

           (e)     In the case of an election under clause (3) of this Section
     402, the Company shall have delivered to the Trustee an Opinion of Counsel
     to the effect that the Holders of such Outstanding Securities and any
     Coupons appertaining thereto 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

                                      38
<PAGE>
 
     the same manner and at the same times as would have been the case if such
     covenant defeasance had not occurred.

           (f)     If the Securities are to be redeemed prior to Stated Maturity
     (other than from mandatory sinking fund payments or analogous payments),
     notice of such redemption shall have been duly given pursuant to this
     Indenture or provision therefor satisfactory to the Trustee shall have been
     made.

           (g)     The Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent to the defeasance or covenant defeasance under clause (2) or (3)
     of this Section 402 (as the case may be) have been complied with.

           (h)     Notwithstanding any other provisions of this Section 402(4),
     such defeasance or covenant defeasance shall be effected in compliance with
     any additional or substitute terms, conditions or limitations which may be
     imposed on the Company in connection therewith pursuant to Section 301.

     (5)   Subject to the provisions of the last paragraph of Section 1003, all
money and Government Obligations (or other property as may be provided pursuant
to Section 301) (including the proceeds thereof) deposited with the Trustee (or
other qualifying trustee, collectively for purposes of this Section 402(5) and
Section 403, the "Trustee") pursuant to clause (4) of Section 402 in respect of
any Outstanding Securities of any series and any Coupons appertaining thereto
shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Securities and any Coupons appertaining thereto 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 Holders of such Securities and any Coupons appertaining
thereto of all sums due and to become due thereon in respect of principal (and
premium, if any) and interest and Additional Amounts, if any, but such money
need not be segregated from other funds except to the extent required by law.

     Unless otherwise specified in or pursuant to this Indenture or any
Securities, if, after a deposit referred to in Section 402(4)(a) has been made,
(a) the Holder of a Security in respect of which such deposit was made is
entitled to, and does, elect pursuant to Section 301 or the terms of such
Security to receive payment in a Currency other than that in which the deposit
pursuant to Section 402(4)(a) has been made in respect of such Security, or (b)
a Conversion Event occurs in respect of the Foreign Currency in which the
deposit pursuant to Section 402(4)(a) has been made, the indebtedness
represented by such Security and any Coupons appertaining thereto shall be
deemed to have been, and will be, fully discharged and satisfied through the
payment of the principal of (and premium, if any), and interest, if any, on, and
Additional Amounts, if any, with respect to, such Security as the same becomes
due out of the proceeds yielded by converting (from time to time as specified
below in the case of any such election) the amount or other property deposited
in respect of such Security into the Currency in which such Security becomes
payable as a result of such election or Conversion Event based on (x) in the
case of payments made pursuant

                                      39
<PAGE>
 
to clause (a) above, the applicable market exchange rate for such Currency in
effect on the second Business Day prior to each payment date, or (y) with
respect to a Conversion Event, the applicable market exchange rate for such
Foreign Currency in effect (as nearly as feasible) at the time of the Conversion
Event.

     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge, imposed on or assessed against the Government Obligations
deposited pursuant to this Section 402 or the principal or interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of such Outstanding Securities and any Coupons
appertaining thereto.

     Anything in this Section 402 to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request any
money or Government Obligations (or other property and any proceeds therefrom)
held by it as provided in clause (4) of this Section 402 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 a
defeasance or covenant defeasance, as applicable, in accordance with this
Section 402.

     Section 403.  Application of Trust Money.

     Subject to the provisions of the last paragraph of Section 1003, all money
and Government Obligations deposited with the Trustee (or other qualifying
Trustee) pursuant to Section 401 or 402 shall be held in trust and applied by
it, in accordance with the provisions of the Securities, the Coupons 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 (or other
qualifying Trustee) may determine, to the Persons entitled thereto, of the
principal, premium, interest and Additional Amounts for whose payment such money
has or Government Obligations have been deposited with or received by the
Trustee (or other qualifying Trustee); but such money and Government Obligations
need not be segregated from other funds except to the extent required by law.

     Section 404.  Effect on Subordination Provisions.

     Unless otherwise expressly provided pursuant to Section 301 with respect to
the Securities of any series, the provisions for subordination of the Securities
set forth in Article Sixteen hereof are hereby expressly made subject to the
provisions for satisfaction and discharge set forth in Section 401 hereof and
the provisions for defeasance and covenant defeasance set forth in Section 402
hereof and, anything herein to the contrary notwithstanding, upon the
effectiveness of such satisfaction and discharge pursuant to Section 401 or any
such defeasance or covenant defeasance pursuant to Section 402 with respect to
the Securities of any series, such Securities shall thereupon cease to be so
subordinated and shall no longer be subject to the provisions of Article Sixteen
hereof and, without limitation to the foregoing, all moneys, Government
Obligations and other securities or property deposited with the Trustee (or
other qualifying trustee) in trust in connection with such satisfaction and
discharge, defeasance or covenant defeasance, as the case may be, and all
proceeds

                                      40
<PAGE>
 
therefrom may be applied to pay the principal of, premium, if any, and interest,
if any, on, and Additional Amounts, if any, with respect to the Securities of
such series as and when the same shall become due and payable notwithstanding
the provisions of Article Sixteen.

     Section 405.  Qualifying Trustee.

     Any trustee appointed pursuant to Section 402 for the purpose of holding
money or Government Obligations deposited pursuant to that Section shall be
appointed under an agreement in form acceptable to the Trustee and shall provide
to the Trustee a certificate of such trustee, upon which certificate the Trustee
shall be entitled to conclusively rely, that all conditions precedent provided
for herein to the related defeasance or covenant defeasance have been complied
with. In no event shall the Trustee be liable for any acts or omissions of said
trustee.

     Section 406.  Reinstatement.

     If the Trustee (or other qualifying trustee) is unable to apply any money
or Government Obligations in accordance with Section 401 or 402, as applicable,
by reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, the Company's
obligations under this Indenture, the Securities and the Coupons, if any,
appertaining thereto shall be revived and reinstated as though no deposit had
occurred pursuant to Section 401 or 402 until such time as the Trustee (or other
qualifying trustee) is permitted to apply all such money or Government
Obligations in accordance with Section 401 or 402, as applicable; provided,
however, that if the Company has made any payment of principal of or any premium
or interest on any Securities or Coupons because of the reinstatement of its
obligations, the Company shall be subrogated to the rights of the Holders of
such Securities or Coupons to receive such payment from the money or Government
Obligations held by the Trustee (or other qualifying trustee).

     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 the Trustee or the Holders of not
less than 25% in principal amount of the Outstanding Securities of such series
may declare the principal of all the Securities of such series, or such lesser
amount as may be provided for in the Securities of such series, to be due and
payable immediately, by a notice in writing to the Company (and to the Trustee
if given by the Holders), and upon any such declaration such principal or such
lesser amount shall become immediately due and payable.

     At any time after Securities of any series have been accelerated 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 not less
than a majority in principal amount of the Outstanding Securities of such
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 of
     money sufficient to pay

                   (a)  all overdue installments of any interest on any
           Securities of such series and any Coupons appertaining thereto and
           any Additional Amounts with respect thereto,

                                      43
<PAGE>
 
                   (b)  the principal of and any premium on any Securities of
           such series which have become due otherwise than by such declaration
           of acceleration and any Additional Amounts with respect thereto and,
           to the extent the payment of such interest is lawful, interest
           thereon at the rate or rates borne by or provided for in such
           Securities,

                   (c)  to the extent that payment of such interest is lawful,
           interest upon overdue installments of any interest and any Additional
           Amounts with respect thereto at the rate or rates borne by or
           provided for 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 all other amounts due the
           Trustee under Section 606; and

           (2)     all Events of Default with respect to Securities of such
     series, other than the non-payment of the principal of, any premium and
     interest on, and any Additional Amounts with respect to Securities of such
     series which shall have become due solely by such declaration of
     acceleration, shall 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 installment of interest
     on, or any Additional Amounts payable in respect of any interest on, any
     Security when such interest or Additional Amounts shall have become 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 any
     premium on, or any Additional Amounts payable in respect of the principal
     of or any premium on, any Security at its Maturity,

the Company shall, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities and any Coupons appertaining thereto,
the whole amount of money then due and payable with respect to such Securities
and any Coupons appertaining thereto, with interest upon the overdue principal,
any premium and, to the extent that payment of such interest shall be legally
enforceable, upon any overdue installments of interest and Additional Amounts at
the rate or rates borne by or provided for in such Securities, and, in addition
thereto, such further amount of money 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 and all other
amounts due to the Trustee under Section 606.

                                      44
<PAGE>
 
     If the Company fails to pay the money it is required to pay the Trustee
pursuant to the preceding paragraph forthwith upon the demand of the Trustee,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the money so due and unpaid, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company or any other obligor upon such Securities and any Coupons
appertaining thereto and collect the monies adjudged or decreed to be payable in
the manner provided by law out of the property of the Company or any other
obligor upon such Securities and any Coupons appertaining thereto, wherever
situated.

     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 and any
Coupons appertaining thereto 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 such Securities or in aid of the exercise of any power granted
herein or therein, or to enforce any other proper remedy.


           Section 504.  Trustee may file proofs of claim.

           In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of any overdue principal, premium, interest or
Additional Amounts) shall be entitled and empowered, by intervention in such
proceeding or otherwise,

                   (1)  to file and prove a claim for the whole amount, or such
           lesser amount as may be provided for in the Securities of such
           series, of the principal and any premium, interest and Additional
           Amounts owing and unpaid in respect of the Securities and any Coupons
           appertaining thereto and to file such other papers or documents as
           may be necessary or advisable in order to have the claims of the
           Trustee (including any claim for the reasonable compensation,
           expenses, disbursements and advances of the Trustee, its agents or
           counsel) and of the Holders of Securities or any Coupons allowed in
           such judicial proceeding, and

                   (2)  to collect and receive any monies or other property
           payable 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 of Securities or any Coupons 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 of Securities or any Coupons, to pay to the Trustee any
amount due

                                      45
<PAGE>
 
to 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 606.

     Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder of a Security
or any Coupon any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or Coupons or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Holder of a
Security or any Coupon in any such proceeding.


     Section 505.  Trustee may Enforce Claims Without Possession of Securities 
or Coupons.

     All rights of action and claims under this Indenture or any of the
Securities or Coupons may be prosecuted and enforced by the Trustee without the
possession of any of the Securities or Coupons 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 or judgment, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, shall be for the ratable benefit of each and every Holder of a
Security or Coupon in respect of which such judgment has been recovered.


     Section 506.  Application of Money Collected.

     Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal, or any
premium, interest or Additional Amounts, upon presentation of the Securities or
Coupons, or both, as the case may be, and the notation thereon of the payment if
only partially paid and upon surrender thereof if fully paid:

           FIRST: To the payment of all amounts due the Trustee and any
     predecessor Trustee under Section 606;

           SECOND: To the payment of amounts then due and unpaid to the holders

           THIRD: To the payment of the amounts then due and unpaid upon the

     Additional Amounts in respect of which or for the benefit of which such
     money has been collected, ratably, without preference or priority of any
     kind, according to the aggregate amounts due and payable on such Securities
     and Coupons for principal and any premium, interest and Additional Amounts,
     respectively;

           FOURTH: The balance, if any, to the Person or Persons entitled
     thereto.

     Section 507.  Limitations on Suits.

     No Holder of any Security of any series or any Coupons appertaining thereto
shall have any right to institute any proceeding, judicial or otherwise, with
respect to this Indenture, or for the appointment of a receiver or trustee, or
for any other remedy hereunder, unless


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

           (2)     the Holders of not less than 25% in principal amount of the
     Outstanding Securities of such 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 reasonable
     indemnity against the costs, expenses and liabilities to be incurred in
     compliance with such request;

           (4)     the Trustee for 60 days after its receipt of such notice,
     request and offer of indemnity has failed to institute any such proceeding;
     and

           (5)     no direction inconsistent with such written request has been
     given to the Trustee during such 60-day period by the Holders of a majority
     in principal amount of the Outstanding Securities of such 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 or any Security to affect, disturb or prejudice the rights of
any other such Holders or Holders of Securities of any other series, 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 such Holders.


     Section 508.  Unconditional Right of Holders to Receive Principal and Any 
                   Premium, Interest and Additional Amounts.

     Notwithstanding any other provision in this Indenture, the Holder of any
Security or Coupon shall have the right, which is absolute and unconditional, to
receive payment of the principal of, any premium and (subject to Sections 305
and 307) interest on, and any Additional Amounts with respect to such Security
or such Coupon, as the case may be, on the respective Stated Maturity or
Maturities therefor specified in such Security or Coupon (or, in the case of
redemption, on the Redemption Date or, in the case of repayment at the option of
such Holder if provided in or pursuant to this Indenture, on the date such
repayment is due) and to institute suit for the enforcement of any such payment,
and such right shall not be impaired without the consent of such Holder.

     Section 509.  Restoration of Rights and Remedies.

     If the Trustee or any Holder of a Security or a Coupon 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 the Company, the Trustee and each such Holder shall, subject to any
determination in such proceeding, be restored severally and respectively to
their former positions hereunder, and thereafter all rights and remedies of the
Trustee and each such Holder shall continue as though no such proceeding had
been instituted.


     Section 510.  Rights and Remedies Cumulative.

     Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities or Coupons in the last paragraph
of Section 306, no right or remedy herein conferred upon or reserved to the
Trustee or to each and every Holder of a Security or a Coupon is intended to be
exclusive of any other right or remedy, and every right and remedy, to the
extent permitted by law, shall 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, to the extent permitted by law, 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 Security or
Coupon 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 any Holder of a Security or a Coupon may be
exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by such Holder, as the case may be.


     Section 512.  Control by Holders of Securities.

     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 and any Coupons appertaining thereto, provided that

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

                                      48
<PAGE>
 
           (2)     the Trustee may take any other action deemed proper by the
     Trustee which is not inconsistent with such direction,

           (3)     such direction is not unduly prejudicial to the rights of the
     other Holders of Securities of such series not joining in such action, and

           (4)     subject to the provisions of Section 601, the Trustee shall
     have the right to decline to follow any such direction if the Trustee in
     good faith shall, by a Responsible Officer or Officers of the Trustee,
     determine that the proceeding so directed would involve the Trustee in
     personal liability.


     Section 513.  Waiver of Past Defaults.
     
     The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series on behalf of the Holders of all the
Securities of such series and any Coupons appertaining thereto may waive any
past default hereunder with respect to such series and its consequences, except
a default

           (1)     in the payment of the principal of, any premium or interest
     on, or any Additional Amounts with respect to, any Security of such series
     or any Coupons appertaining thereto, 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.  Waiver of Stay or Extension Laws.

     The Company covenants that (to the extent that it may lawfully do so) it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any 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 expressly waives (to the extent
that it may lawfully do so) 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 515.  Undertaking for Costs.

     All parties to this Indenture agree, and each Holder of any Security by his
acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, 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 or
omitted by it as Trustee, the filing by any party litigant in such suit of any
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit having due regard to the merits and good
faith of the claims or defenses made by such party litigant; but the provisions
of this Section 515 shall not apply to any suit instituted by the Trustee, to
any suit instituted by any Holder, or group of Holders, holding in the aggregate
more than 10% in principal amount of Outstanding Securities of any series, or to
any suit instituted by any Holder for the enforcement of the payment of the
principal of (or premium, if any) or interest, if any, on or Additional Amounts,
if any, with respect to any Security on or after the respective Stated
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date, and, in the case of repayment, on or after the date
for repayment) or for the enforcement of the right, if any, to convert or
exchange any Security into Common Stock or other securities in accordance with
its terms.

     believed by it to be genuine and to have been signed or presented by the

     taking, suffering or omitting any action hereunder, the Trustee (unless
     other evidence shall be herein specifically prescribed) may, in the absence
     of bad faith on its part, rely upon an Officers' Certificate;

                                      50
<PAGE>
 
           (4)     the Trustee may consult with counsel and the written advice
     of such counsel or any Opinion of Counsel shall be full and complete
     authorization and protection in respect of any action taken, suffered or
     omitted by it hereunder in good faith and in reliance thereon;

           (5)     the Trustee shall be under no obligation to exercise any of
     the rights or powers vested in it by or pursuant to this Indenture at the

directors, the executive committee or a trust committee of directors and/or
Responsible Officers of the Trustee in good faith determine that the withholding
of such notice is in the best interest of the Holders of Securities and Coupons
of such series; and provided, further, that in the case of any default of the
character specified in Section 501(4) with respect to Securities of such series,
no such

         Except as provided in Section 403 and Section 1003, money held by the

         including the costs and expenses of defending themselves against any
         claim or liability in connection with the exercise or performance of
         any of their powers or duties hereunder, except to the extent that any
         such loss, liability or expense was due to the Trustee's negligence or
         bad faith.

         As security for the performance of the obligations of the Company under
this Section, the Trustee shall have a lien prior to the Securities of any
series upon all property and funds held or collected by the Trustee as such,
except funds held in trust for the payment of principal of, and premium or
interest on or any Additional Amounts with respect to particular Securities or
any Coupons appertaining thereto.

         Without limiting any rights available to the Trustee under applicable
law, any compensation or expense incurred by the Trustee after a default
specified by Section 501(5) or (6) is intended to constitute an expense of
administration under any then applicable bankruptcy or insolvency law. "Trustee"

negligence or bad faith of any Trustee shall not affect the rights of any other
Trustee under this Section 606.

         (3) 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

Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment in accordance with the applicable requirements of Section

Authorized Newspaper in each Place of Payment located outside the United States.
Each notice shall include the name of the successor Trustee with respect to the
Securities of such series and the address of its Corporate Trust Office.


         Section 609.       Acceptance of Appointment by Successor.

         (1) Upon the appointment hereunder of any successor Trustee with
respect to all Securities, such successor Trustee so appointed shall execute,
acknowledge and deliver to the Company and 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 hereunder of the retiring Trustee; but, on the request
of the Company or such successor Trustee, such retiring Trustee, upon payment of
its charges, shall execute and deliver an instrument transferring to such
successor Trustee all the rights, powers and trusts of the retiring Trustee and,
subject to Section 1003, shall duly assign, transfer and deliver to such
successor Trustee all property and money held by such retiring Trustee
hereunder, subject nevertheless to its lien, if any, provided for in Section
606.

desirable to transfer and confirm to, and to vest in, such 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

                                      55
<PAGE>
 
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, 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 that no
Trustee shall be responsible for any notice given to, or received by, or any act
or failure to act on the part of any other Trustee hereunder, 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, such retiring Trustee shall have no further responsibility for the
exercise of rights and powers or for the performance of the duties and
obligations vested in the Trustee under this Indenture with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates other than as hereinafter expressly set forth, 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
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 such
successor Trustee, such retiring Trustee, upon payment of its charges with
respect to the Securities of that or those series to which the appointment of
such successor relates and subject to Section 1003 shall duly assign, transfer
and deliver to such successor Trustee, to the extent contemplated by such
supplemental indenture, the 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, subject to its lien, if any,
provided for in Section 606.

         (3) Upon request of any Person appointed hereunder as a 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 (1) or (2) of this Section, as the
case may be.

         (4) No Person shall accept its appointment hereunder as a successor
Trustee unless at the time of such acceptance such successor Person shall be
qualified under the Trust Indenture Act and eligible under this Article.


         Section 610. 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 of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
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

                                      56
<PAGE>
 
authentication and deliver the Securities so authenticated with the same effect
as if such successor Trustee had itself authenticated such Securities.


         Section 611.       Appointment of Authenticating Agent.

         The Trustee may appoint one or more Authenticating Agents acceptable to
the Company with respect to one or more series of Securities which shall be
authorized to act on behalf of the Trustee to authenticate Securities of that or
those series issued upon original issue, exchange, registration of transfer,
partial redemption or partial repayment, 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,
except as provided in or pursuant to this Indenture, shall at all times be a
corporation that would be permitted by the Trust Indenture Act to act as trustee
under an indenture qualified under the Trust Indenture Act, is authorized under
applicable law and by its charter to act as an Authenticating Agent and has a
combined capital and surplus (computed in accordance with Section 310(a)(2) of
the Trust Indenture Act) of at least $50,000,000. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, it 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 of
the corporate agency or corporate trust business of an Authenticating Agent,
shall be the successor of such Authenticating Agent hereunder, 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 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 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 (i) mail written notice
of such appointment by first-class mail, postage prepaid, to all Holders of
Registered Securities, if any, of the series with respect to which such
Authenticating Agent shall serve, as their names and addresses appear in the
Security Register, and (ii) if Securities of the series are issued as Bearer
Securities, publish notice of such appointment at least once in an

                                      57
<PAGE>
 
Authorized Newspaper in the place where such successor Authenticating Agent has
its principal office if such office is located outside the United States. 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 Company agrees to pay each Authenticating Agent from time to time
reasonable compensation for its services under this Section. If the Trustee
makes such payments, it shall be entitled to be reimbursed for such payments,
subject to the provisions of Section 606.

         The provisions of Sections 308, 603 and 604 shall be applicable to each
Authenticating Agent.

         If an Authenticating Agent is appointed with respect to one or more
series of Securities 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 alternate certificate of authentication in substantially the
following form:

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

         [Date]             THE CHASE MANHATTAN BANK,
                            As Trustee

                               -------------------------------------------------
                                    Authorized Officer


         If all of the Securities of any series may not be originally issued at
one time, and if the Trustee does not have an office capable of authenticating
Securities upon original issuance located in a Place of Payment where the
Company wishes to have Securities of such series authenticated upon original
issuance, the Trustee, if so requested in writing (which writing need not be
accompanied by or contained in an Officers' Certificate by the Company), shall
appoint in accordance with this Section and such procedures as shall be
acceptable to the Trustee an Authenticating Agent having an office in a Place of
Payment designated by the Company with respect to such series of Securities.

         set forth; or

         to one or more series of Securities or to one or more Securities within
         any series as specified in such supplemental indenture or indentures),
         provided that such amendment or supplement does not apply to any
         Outstanding Security issued prior to the date of such supplemental
         indenture and entitled to the benefits of such provision.


         Section 902.   Supplemental Indentures with Consent of Holders.

         With the consent of the Holders of not less than a majority in
principal amount of the Outstanding Securities of each series affected by such
supplemental indenture, by Act of said Holders delivered to the Company and the
Trustee, the Company (when authorized by or pursuant to a Board Resolution), and
the Trustee may enter into an indenture or indentures supplemental hereto for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of this Indenture or of the Securities of such series or
of modifying in any manner the rights of the Holders of Securities of such
series under this Indenture; provided, however, that no such supplemental
indenture, without the consent of the Holder of each Outstanding Security
affected thereby, shall

                  (1)   change the Stated Maturity of the principal of, or any
         premium or installment of interest on or any Additional Amounts with
         respect to, any Security, or reduce the

                                      63
<PAGE>
 
         principal amount thereof or the rate (or modify the calculation of such
         rate) of interest thereon or any Additional Amounts with respect
         thereto, or any premium payable upon the redemption thereof or
         otherwise, or change the obligation of the Company to pay Additional
         Amounts pursuant to Section 1004, or reduce the amount of the principal
         of an Original Issue Discount Security that would be due and payable
         upon a declaration of acceleration of the Maturity thereof pursuant to
         Section 502 or the amount thereof provable in bankruptcy pursuant to
         Section 504, adversely affect the right of repayment at the option of
         any Holder as contemplated by Article Thirteen, or change the Place of
         Payment, Currency in which the principal of, any premium or interest
         on, or any Additional Amounts with respect to any Security 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, in the case of
         repayment at the option of the Holder, on or after the date for
         repayment), or

                  (2) reduce the percentage in principal amount of the
         Outstanding Securities of any series, the consent of whose Holders is
         required for any such supplemental indenture, or the consent of whose
         Holders is required for any waiver of certain defaults hereunder and
         their consequences provided for in this Indenture, or reduce the
         requirements of Section 1504 for quorum or voting, or

                  (3) modify any of the provisions of Article Sixteen or the
         definition of "Senior Indebtedness" in a manner adverse to the Holders
         of Securities, or

                  (4) modify any of the provisions of this Section or Section
         513, except to increase any such percentage 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, or

                  (5) make any change that adversely affects the right to
         convert or exchange any Security for Common Stock or other securities
         in accordance with its terms.

         A supplemental indenture which changes or eliminates any covenant or
other provision of this Indenture which shall have been included expressly and
solely for the benefit of one or more particular series of Securities, or which
modifies the rights of the Holders of Securities of such series with respect to
such covenant or other provision, shall be deemed not to affect the rights under
this Indenture of the Holders of Securities of any other series.

         It shall not be necessary for any Act of Holders of Securities under
this Section to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such Act shall approve the substance
thereof.

         Section 903.   Execution of Supplemental Indentures.

         As a condition to executing, or accepting the additional trusts created
by, any supplemental indenture permitted by this Article or the modifications
thereby of the trust created by this Indenture, the Trustee shall be entitled to
receive, and (subject to Section 315 of the Trust Indenture Act) shall be fully
protected in relying upon, an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture. The
Trustee may, but shall not be obligated to, enter into any such supplemental
indenture which affects the 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,
this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of a Security theretofore or thereafter authenticated and delivered hereunder
and of any Coupon appertaining thereto shall be bound thereby.


         Section 905.   Reference in Securities to Supplemental Indentures.

         Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to this Article may, and shall
if required by the Trustee, bear a notation in form approved by the Trustee as
to any matter provided for in such supplemental indenture. If the Company shall
so determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee and the Company, to any such supplemental indenture may
be prepared and executed by the Company and authenticated and delivered by the
Trustee in exchange for Outstanding Securities of such series.


         Section 906.   Effect on Senior Indebtedness.

         No supplemental indenture shall directly or indirectly modify or
eliminate the provisions of Article Sixteen or the definition of "Senior
Indebtedness" in any manner which might terminate or impair the subordination of
the Securities to Senior Indebtedness without the prior written consent of the
Holders of the Senior Indebtedness.


         Section 907.   Conformity with Trust Indenture Act.

         Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act as then in effect.

         Section 1001. Payment of Principal, Any Premium, Interest and 
Additional Amounts.

         The Company covenants and agrees for the benefit of the Holders of the
Securities of each series that it will duly and punctually pay the principal of,
any premium and interest on and any Additional Amounts with respect to the
Securities of such series in accordance with the terms thereof, any Coupons
appertaining thereto and this Indenture. Any interest due on any Bearer Security
on or before the Maturity thereof, and any Additional Amounts payable with
respect to such interest, shall be payable only upon presentation and surrender
of the Coupons appertaining thereto for such interest as they severally mature.


         Section 1002. Maintenance of Office or Agency.

         The Company shall maintain in each Place of Payment for any series of
Securities an Office or Agency where Securities of such series (but not Bearer
Securities, except as otherwise provided below, unless such Place of Payment is
located outside the United States) may be presented or surrendered for payment,
where Securities of such series may be surrendered for registration of transfer
or exchange, where Securities of such series that are convertible or
exchangeable may be surrendered for conversion or exchange, and where notices
and demands to or upon the Company in respect of the Securities of such series
relating thereto and this Indenture may be served. If Securities of a series are
issuable as Bearer Securities, the Company shall maintain, subject to any laws
or regulations applicable thereto, an Office or Agency in a Place of Payment for
such series which is located outside the United States where Securities of such
series and any Coupons appertaining thereto may be presented and surrendered for
payment; provided, however, that if the Securities of such series are listed on
The Stock Exchange of the United Kingdom and the Republic of Ireland or the
Luxembourg Stock Exchange or any other stock exchange located outside the United
States and such stock exchange shall so require, the Company shall maintain a
Paying Agent in London, Luxembourg or any other required city located outside
the United States, as the case may be, so long as the Securities of such series
are listed on such exchange. 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, except that Bearer Securities of such
series and any Coupons appertaining thereto may be presented and surrendered for
payment at the place specified for the purpose with respect to such Securities
as provided in or pursuant to this Indenture, and the Company hereby appoints
the Trustee as its agent to receive all such presentations, surrenders, notices
and demands.

                                      66
<PAGE>
 
         Except as otherwise provided in or pursuant to this Indenture, no
payment of principal, premium, interest or Additional Amounts with respect to
Bearer Securities shall be made at any Office or Agency in the United States or
by check mailed to any address in the United States or by transfer to an account
maintained with a bank located in the United States; provided, however, if
amounts owing with respect to any Bearer Securities shall be payable in Dollars,
payment of principal of, any premium or interest on and any Additional Amounts
with respect to any such Security may be made at the Corporate Trust Office of
the Trustee or any Office or Agency designated by the Company in the Borough of
Manhattan, The City of New York, if (but only if) payment of the full amount of
such principal, premium, interest or Additional Amounts at all offices outside
the United States maintained for such purpose by the Company in accordance with
this Indenture is illegal or effectively precluded by exchange controls or other
similar restrictions.

         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 shall 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. Unless otherwise provided in or pursuant to this
Indenture, the Company hereby designates as the Place of Payment for each series
of Securities the Borough of Manhattan, The City of New York, and initially
appoints the Corporate Trust Office of the Trustee as the Company's Office or
Agency in the Borough of Manhattan, The City of New York for such purpose. The
Company may subsequently appoint a different Office or Agency in the Borough of
Manhattan, The City of New York for the Securities of any series.


         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 shall, on or before each due date of the
principal of, any premium or interest on or Additional Amounts with respect to
any of the Securities of such series, segregate and hold in trust for the
benefit of the Persons entitled thereto a sum 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
principal or any premium, interest or Additional Amounts so becoming due until
such sums shall be paid to such Persons or otherwise disposed of as herein
provided, and shall 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 shall, on or prior to each due date of the principal
of, any premium or interest on or any Additional Amounts with respect to any
Securities of such series, deposit with any Paying Agent a sum (in the Currency
or Currencies described in the preceding paragraph) sufficient to pay the
principal or any premium, interest or Additional Amounts so becoming due, such
sum to be held in trust for the benefit of the Persons entitled thereto, and
(unless such Paying Agent is the Trustee) the Company will promptly notify the
Trustee of its action or failure so to act.


                                      67
<PAGE>
 
         The Company shall 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 shall:

                  (1) hold all sums held by it for the payment of the principal
         of, any premium or interest on or any Additional Amounts with respect
         to Securities of such series in trust for the benefit of the Persons
         entitled thereto until such sums shall be paid to such Persons or
         otherwise disposed of as provided in or pursuant to this Indenture;

                  (2) give the Trustee notice of any default by the Company (or
         any other obligor upon the Securities of such series) in the making of
         any payment of principal, any premium or interest on or any Additional
         Amounts with respect to the Securities of such series; and

                  (3) at any time during the continuance of any such default,
         upon the written request of the Trustee, forthwith pay to the Trustee
         all sums so held in trust by such Paying Agent.

         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 terms 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 sums.

         Except as otherwise provided herein or pursuant hereto, 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, any premium or interest on or any
Additional Amounts with respect to any Security of any series or any Coupon
appertaining thereto and remaining unclaimed for two years after such principal
or any such premium or interest or any such Additional Amounts shall have 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 or any Coupon appertaining thereto 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 an Authorized Newspaper in each Place of Payment for such
series or to be mailed to Holders of Registered Securities of such series, or
both, 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
or mailing nor shall it be later than two years after such principal and any
premium or interest or Additional Amounts shall have become due and payable, any
unclaimed balance of such money then remaining will be repaid to the Company.

         Section 1004.  Additional Amounts.

         If any Securities of a series provide for the payment of Additional
Amounts, the Company agrees to pay to the Holder of any such Security or any
Coupon appertaining thereto Additional Amounts as provided in or pursuant to
this Indenture or such Securities. Whenever in this Indenture there is
mentioned, in any context, the payment of the principal of or any premium or
interest on, or in respect of, any Security of any series or any Coupon or the
net proceeds received on the sale or exchange of any Security of any series,
such mention shall be deemed to include mention of the payment of Additional
Amounts provided by the terms of such series established hereby or pursuant
hereto to the extent that, in such context, Additional Amounts are, were or
would be payable in respect thereof pursuant to such terms, and express mention
of the payment of Additional Amounts (if applicable) in any provision hereof
shall not be construed as excluding Additional Amounts in those provisions
hereof where such express mention is not made.

         Except as otherwise provided in or pursuant to this Indenture or the
Securities of any series, if the Securities of a series provide for the payment
of Additional Amounts, at least 10 days prior to the first Interest Payment Date
with respect to such series of Securities (or if the Securities of such series
shall not bear interest prior to Maturity, the first day on which a payment of
principal is made), and at least 10 days prior to each date of payment of
principal or interest if there has been any change with respect to the matters
set forth in the below-mentioned Officers' Certificate, the Company shall
furnish to the Trustee and the principal Paying Agent or Paying Agents, if other
than the Trustee, an Officers' Certificate instructing the Trustee and such
Paying Agent or Paying Agents whether such payment of principal of and premium,
if any, or interest, if any, on the Securities of such series shall be made to
Holders of Securities of such series or the Coupons appertaining thereto who are
United States Aliens without withholding for or on account of any tax,
assessment or other governmental charge described in the Securities of such
series. If any such withholding shall be required, then such Officers'
Certificate shall specify by country the amount, if any, required to be withheld
on such payments to such Holders of Securities or Coupons, and the Company
agrees to pay to the Trustee or such Paying Agent the Additional Amounts
required by the terms of such Securities. The Company covenants to indemnify the
Trustee and any Paying Agent for, and to hold them harmless against, any loss,
liability or expense reasonably incurred without negligence or bad faith on
their part arising out of or in connection with actions taken or omitted by any
of them in reliance on any Officers' Certificate furnished pursuant to this
Section.


         Section 1005.  Company Statement as to Compliance.

         The Company will deliver to the Trustee, within 120 days after the end
of each fiscal year, an Officers' Certificate (which need not comply with
Section 102), stating as to each signer, that

                  (1) a review of the activities of the Company during such year
         and of performance under this Indenture has been made under his or her
         supervision; and


                                      69
<PAGE>
 
                  (2) to the best of his or her knowledge, based on such review,
         (a) the Company has fulfilled all its obligations under and complied
         with all covenants and conditions contained in this Indenture
         throughout such year, or, if there has been a default in the
         fulfillment of any such covenant, condition or obligation, specifying
         each such default known to him or her and the nature and status
         thereof, and (b) no event has occurred and is continuing which is, or
         after notice or lapse of time or both would become, an Event of Default
         under Section 501, or, if such an event has occurred and is continuing,
         specifying each such event known to him or her and the nature and
         status thereof.

At least one of the Person's signing such Officers' Certificate shall be the
Company's principal executive officer, principal financial officer or principal
accounting officer.

                           REDEMPTION OF SECURITIES


         Section 1101.  Applicability of Article.

         Redemption of Securities of any series at the option of the Company as
permitted or required by the terms of such Securities shall be made in
accordance with the terms of such Securities and (except as otherwise provided
herein or pursuant hereto) 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. In case of any redemption at the election
of the Company of less than all 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 and of the principal amount of Securities of
such series to be redeemed and, in the event that the Company shall determine
that the Securities of any series to be redeemed shall be selected from
Securities of such series having the same issue date, interest rate or interest
rate formula, Stated Maturity and other terms (the "Equivalent Terms"), the
Company shall notify the Trustee of such Equivalent Terms. In the case of any
redemption of Securities (a) prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this
Indenture or (b) pursuant to an election of the Company which is subject to a
condition specified 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 or condition.

         Section 1103.  Selection by Trustee of Securities to be Redeemed.

         If less than all of the Securities of any series are to be redeemed
(unless all of the Securities of any series with Equivalent Terms are to be
redeemed) or if less than all of the Securities of any series with Equivalent
Terms 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 or from the Outstanding Securities of
such series with Equivalent Terms, as the case may be, 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 of portions of the principal
amount of Registered Securities of such series; provided, however, that no such
partial redemption shall reduce the portion of the principal amount of a
Registered Security of such series not redeemed to less than the minimum
denomination for a Security of such series established herein or pursuant
hereto.

         The Trustee shall promptly notify the Company and the Security
Registrar (if other than itself) 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 of such Securities which has been or is to be redeemed.

         Unless otherwise specified in or pursuant to this Indenture or the
Securities of any series, if any Security selected for partial redemption is
converted or exchanged for Common Stock or other securities in part before
termination of the conversion or exchange right with respect to the portion of
the Security so selected, the converted or exchanged portion of such Security
shall be deemed (so far as may be) to be the portion selected for redemption.
Securities which have been converted or exchanged during a selection of
Securities to be redeemed shall be treated by the Trustee as Outstanding for the
purpose of such selection.


         Section 1104.  Notice of Redemption.

         Notice of redemption shall be given in the manner provided in Section
106, not less than 30 nor more than 60 days prior to the Redemption Date, unless
a shorter period is specified in the Securities to be redeemed, to the Holders
of Securities to be redeemed. Failure to give notice by mailing in the manner
herein provided to the Holder of any Registered Securities designated for
redemption as a whole or in part, or any defect in the notice to any such
Holder, shall not affect the validity of the proceedings for the redemption of
any other Securities or portion thereof.

         Any notice that is mailed to the Holder of any Registered Securities in
the manner herein provided shall be conclusively presumed to have been duly
given, whether or not such Holder receives the notice.


                                      71

         All notices of redemption shall state:

                  (1)  the Redemption Date,

                  (2)  the Redemption Price,

                  (3)  if less than all Outstanding Securities of any series are
         to be redeemed (unless all of the Securities of any series with
         Equivalent Terms are to be redeemed), the identification (and, in the
         case of partial redemption, the principal amount) of the particular
         Security or Securities to be redeemed,

                  (4)  in case any Security is to be redeemed in part only, the
         notice which relates to such Security shall state that on and after the
         Redemption Date, upon surrender of such Security, the Holder of such
         Security will receive, without charge, a new Security or Securities of
         authorized denominations for the principal amount thereof remaining
         unredeemed,

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

                  (6)  the place or places where such Securities, together (in
         the case of Bearer Securities) with all Coupons appertaining thereto,
         if any, maturing after the Redemption Date, are to be surrendered for
         payment of the Redemption Price and any accrued interest and Additional
         Amounts pertaining thereto,

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

                  (8)  that, unless otherwise specified in such notice, Bearer
         Securities of any series, if any, surrendered for redemption must be
         accompanied by all Coupons maturing subsequent to the date fixed for
         redemption or the amount of any such missing Coupon or Coupons will be
         deducted from the Redemption Price, unless security or indemnity
         satisfactory to the Company, the Trustee and any Paying Agent is
         furnished,

                  (9)  if Bearer Securities of any series are to be redeemed and
         any Registered Securities of such series are not to be redeemed, and if
         such Bearer Securities may be exchanged for Registered Securities not
         subject to redemption on the Redemption Date pursuant to Section 305 or
         otherwise, the last date, as determined by the Company, on which such
         exchanges may be made,

                  (10) in the case of Securities of any series that are
         convertible or exchangeable into Common Stock or other securities, the
         conversion or exchange price or rate, the date or dates on which the

                  (11) the CUSIP number or the Euroclear or the Cedel reference
         numbers of such Securities, if any (or any other numbers used by a U.S.
         Depository or Depository to identify such Securities).

         A notice of redemption published as contemplated by Section 106 need
not identify particular Registered Securities to be redeemed.

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


         Section 1105.  Deposit of Redemption Price.

         On or prior to any Redemption Date, the Company shall deposit, with
respect to the Securities of any series called for redemption pursuant to
Section 1104, 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 applicable Currency sufficient to pay
the Redemption Price of, and (except if the Redemption Date shall be an Interest
Payment Date, unless otherwise specified pursuant to Section 301 for or in the
Securities of such series) any accrued interest on and Additional Amounts with
respect thereto, all such 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 and the Coupons for such
interest appertaining to any Bearer Securities so to be redeemed, except to the
extent provided below, shall be void. Upon surrender of any such Security for
redemption in accordance with said notice, together with all Coupons, if any,
appertaining thereto maturing after the Redemption Date, such Security shall be
paid by the Company at the Redemption Price, together with any accrued interest
and Additional Amounts to the Redemption Date; provided, however, that, except
as otherwise provided in or pursuant to this Indenture or the Bearer Securities
of such series, installments of interest on Bearer Securities whose Stated
Maturity is on or prior to the Redemption Date shall be payable only upon
presentation and surrender of Coupons for such interest (at an Office or Agency
located outside the United States except as otherwise provided in Section 1002),
and provided, further, that, except as otherwise specified in or pursuant to
this Indenture or the Registered Securities of such series, installments of
interest on Registered Securities whose Stated Maturity is


                                      73
<PAGE>
 
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 Regular Record Dates therefor according to their terms
and the provisions of Section 307.

         If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant Coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing Coupons, or the surrender of such missing
Coupon or Coupons may be waived by the Company and the Trustee if there be
furnished to them such security or indemnity as they may require to save each of
them and any Paying Agent harmless. If thereafter the Holder of such Security
shall surrender to the Trustee or any Paying Agent any such missing Coupon in
respect of which a deduction shall have been made from the Redemption Price,
such Holder shall be entitled to receive the amount so deducted; provided,
however, that any interest or Additional Amounts represented by Coupons shall be
payable only upon presentation and surrender of those Coupons at an Office or
Agency for such Security located outside of the United States except as
otherwise provided in Section 1002.

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


         Section 1107.  Securities Redeemed in Part.

         Any Registered Security which is to be redeemed only in part shall be
surrendered at any Office or Agency for such Security (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 to the Holder of such
Security without service charge, a new Registered Security or Securities of the
same series, containing identical terms and provisions, 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. If a Security in global form is so surrendered, the Company shall
execute, and the Trustee shall authenticate and deliver to the U.S. Depository
or other Depository for such Security in global form as shall be specified in
the Company Order with respect thereto to the Trustee, without service charge, a
new Security in global form in a denomination equal to and in exchange for the
unredeemed portion of the principal of the Security in global form 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 permitted or
required in or pursuant to this Indenture or any Security of such series issued
pursuant to this Indenture.

         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 such 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 and this Indenture.


         Section 1202.  Satisfaction of Sinking Fund Payments with Securities.

         The Company may, in satisfaction of all or any part of any sinking fund
payment with respect to the Securities of any series to be made pursuant to the
terms of such Securities (1) deliver Outstanding Securities of such series
(other than any of such Securities previously called for redemption or any of
such Securities in respect of which cash shall have been released to the
Company), together in the case of any Bearer Securities of such series with all
unmatured Coupons appertaining thereto, and (2) apply as a credit Securities of
such series which have been redeemed either at the election of the Company
pursuant to the terms of such series of Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, 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. If as a result of the delivery or credit of Securities
of any series in lieu of cash payments pursuant to this Section 1202, the
principal amount of Securities of such series to be redeemed in order to exhaust
the aforesaid cash payment shall be less than $100,000, the Trustee need not
call Securities of such series for redemption, except upon Company Request, and
such cash payment shall be held by the Trustee or a Paying Agent and applied to
the next succeeding sinking fund payment, provided, however, that the Trustee or
such Paying Agent shall at the request of the Company from time to time pay over
and deliver to the Company any cash payment so being held by the Trustee or such
Paying Agent upon delivery by the Company to the Trustee of Securities of that
series purchased by the Company having an unpaid principal amount equal to the
cash payment requested to be released to the Company.

         Section 1203.  Redemption of Securities for Sinking Fund.

         Not less than 75 days prior to each sinking fund payment date for any
series of Securities, the Company shall deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing mandatory 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 of
Securities of that series pursuant to Section 1202, the basis for such credit,
that such Securities have not been previously so credited and the optional
amount, if any, to be added in cash to the next ensuing mandatory sinking fund
payment, and will also deliver to the Trustee any Securities to be so credited
and not theretofore delivered. If such Officers' Certificate shall specify an
optional amount to be added in cash to the next ensuing mandatory sinking fund
payment, the Company shall thereupon be obligated to pay the amount therein
specified. Not less than 45 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.


                               ARTICLE THIRTEEN

                      REPAYMENT AT THE OPTION OF HOLDERS


         Section 1301.  Applicability of Article.

         Securities of any series which are repayable at the option of the
Holders thereof before their Stated Maturity shall be repaid in accordance with
the terms of the Securities of such series. The repayment of any principal
amount of Securities pursuant to such option of the Holder to require repayment
of Securities before their Stated Maturity, for purposes of Section 309, shall
not operate as a payment, redemption or satisfaction of the Indebtedness
represented by such Securities unless and until the Company, at its option,
shall deliver or surrender the same to the Trustee with a directive that such
Securities be cancelled. Notwithstanding anything to the contrary contained in
this Section 1301, in connection with any repayment of Securities, the Company
may arrange for the purchase of any Securities by an agreement with one or more
investment bankers or other purchasers to purchase such Securities by paying to
the Holders of such Securities on or before the close of business on the
repayment date an amount not less than the repayment price payable by the
Company on repayment of such Securities, and the obligation of the Company to
pay the repayment price of such Securities shall be satisfied and discharged to
the extent such payment is so paid by such purchasers.

                       SECURITIES IN FOREIGN CURRENCIES


         Section 1401.  Applicability of Article.

         Whenever this Indenture provides for any distribution to Holders of
Securities of any series in which not all of such Securities are denominated in
the same Currency, in the absence of any provision to the contrary in or
pursuant to this Indenture or the Securities of such series, any amount in
respect of any Security denominated in a Currency other than Dollars shall be
treated for any such distribution as that amount of Dollars that could be
obtained for such amount on such reasonable basis of exchange and as of the
record date with respect to Registered Securities of such series (if any) for
such distribution (or, if there shall be no applicable record date, such other
date reasonably proximate to the date of such distribution) as the Company may
specify in a written notice to the Trustee or, in the absence of such written
notice, as the Trustee may determine.

present as aforesaid may be adopted only by the affirmative vote of the Holders
of a majority in principal amount of the Outstanding Securities of that series;
provided, however, that, except as limited by the proviso to Section 902, any

appointment of any proxy shall be proved in the manner specified in Section 104
or by having the signature of the person executing the proxy witnessed or

chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders of Securities as provided in Section 1502(2), in which

         the indebtedness evidenced by the Securities; and

                  (2) any payment or distribution of assets of the Company of
         any kind or character, whether in cash, property or securities, to
         which the Holders of the Securities or the Trustee would be entitled
         except for the provisions of this Article Sixteen shall be paid by the
         liquidating trustee or agent or other person making such payment or
         distribution, whether a trustee in bankruptcy, a receiver or
         liquidating trustee or otherwise, directly to the holders of Senior
         Indebtedness or their representative or representatives or to the
         trustee or trustees under any indenture under which any instruments
         evidencing any of such Senior Indebtedness may have been issued,
         ratably according to the aggregate amounts remaining unpaid on account
         of the principal of (and premium, if any) and interest on the Senior
         Indebtedness held or represented by each, to the extent necessary to
         make payment in full of all Senior Indebtedness remaining


                                      81
<PAGE>
 
     unpaid, after giving effect to any concurrent payment or distribution to
     the holders of such Senior Indebtedness; and

           (3)   in the event that, notwithstanding the foregoing, any payment
     or distribution of assets of the Company of any kind or character, whether
     in cash, property or securities, shall be received by the Trustee or the
     Holders of the Securities before all Senior Indebtedness is paid in full,
     such payment or distribution shall be paid over, upon written notice to the
     Trustee, to the holders of such Senior Indebtedness or their representative
     or representatives or to the trustee or trustees under any indenture under
     which any instrument evidencing any of such Senior Indebtedness may have
     been issued, ratably as aforesaid, for application to payment of all Senior
     Indebtedness remaining unpaid until all such Senior Indebtedness shall have
     been paid in full, after giving effect to any concurrent payment or
     distribution to the holders of such Senior Indebtedness.

     Subject to the payment in full of all Senior Indebtedness, the Holders of
the Securities shall be subrogated to the rights of the holders of Senior
Indebtedness to receive payments or distributions of cash, property or
securities of the Company applicable to Senior Indebtedness until the principal
of (and premium, if any) and interest, if any, on, or Additional Amounts, if
any, in respect of the Securities shall be paid in full and no such payments or
distributions to the Holders of the Securities of cash, property or securities
otherwise distributable to the holders of Senior Indebtedness shall, as between
the Company, its creditors other than the holders of Senior Indebtedness, and
the Holders of the Securities be deemed to be a payment by the Company to or on
account of the Securities. It is understood that the provisions of this Article
Sixteen are and are intended solely for the purpose of defining the relative
rights of the Holders of the Securities, on the one hand, and the holders of the
Senior Indebtedness, on the other hand. Nothing contained in this Article
Sixteen or elsewhere in this Indenture or in the Securities is intended to or
shall impair, as between the Company, its creditors other than the holders of
Senior Indebtedness, and the Holders of the Securities, the obligation of the
Company, which is unconditional and absolute, to pay to the Holders of the
Securities the principal of (and premium, if any) and interest, if any, on, or
Additional Amounts, if any, in respect of the Securities as and when the same
shall become due and payable in accordance with their terms, or to affect the
relative rights of the Holders of the Securities and creditors of the Company
other than the holders of Senior Indebtedness, nor shall anything herein or in
the Securities 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 Sixteen of the
holders of Senior Indebtedness in respect of cash, property or securities of the
Company received upon the exercise of any such remedy.

     The Trustee, however, shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness. The Trustee shall not be liable to any such
holder if it shall pay over or distribute to or on behalf of Holders of
Securities or the Company moneys or assets to which any holder of Senior
Indebtedness shall be entitled by virtue of this Article Sixteen.

                                      82
<PAGE>
 
     If the Trustee or any Holder of Securities does not file a proper claim or
proof of debt in the form required in any proceeding referred to above prior to
30 days before the expiration of the time to file such claim in such proceeding,
then the holder of any Senior Indebtedness is hereby authorized, and has the
right, to file an appropriate claim or claims for or on behalf of such Holder of
Securities.

     Section 1603.   No Payment on Securities in Event of Default on Senior 
                     Indebtedness.

     No payment by the Company on account of principal (or premium, if any),
sinking funds or interest, if any, on, or Additional Amounts, if any, in respect
of the Securities shall be made unless full payment of amounts then due for the
principal of (and premium, if any), sinking funds and interest, if any, on
Senior Indebtedness has been made or duly provided for in money or money's
worth.

     Section 1604.   Payments on Securities Permitted.

     Nothing contained in this Indenture or in any of the Securities shall (a)
affect the obligation of the Company to make, or prevent the Company from
making, at any time except as provided in Sections 1602 and 1603, payments of
principal of (or premium, if any) or interest, if any, on, or Additional Amounts
or sinking fund payments, if any, with respect to the Securities or (b) prevent
the application by the Trustee of any moneys deposited with it hereunder to the
payment of or on account of the principal of (or premium, if any) or interest,
if any, on, or Additional Amounts, if any, in respect of the Securities, unless
the Trustee shall have received at its Corporate Trust Office written notice
from the Company or from the holder of any Senior Indebtedness or from the
trustee for or representative of any such holder of any event prohibiting the
making of such payment at least two Business Days prior to the date fixed for
such payment.

     Section 1605.   Authorization of Holders to Trustee to Effect
                     Subordination.

     Each Holder of Securities 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 as provided in this Article Sixteen and appoints
the Trustee his attorney-in-fact for any and all such purposes.

     Section 1606.   Notices 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 pursuant to this Article Sixteen. Failure
to give such notice shall not affect the subordination of the Securities to
Senior Indebtedness. Notwithstanding the provisions of this Article Sixteen or
any other provisions of this Indenture, neither the Trustee nor any Paying Agent
(other than the Company) shall be charged with knowledge of the existence of any
Senior Indebtedness or of any event which would prohibit the making of any
payment of moneys to or by the Trustee or such Paying Agent, unless and until
the Trustee or such Paying Agent shall

                                      83
<PAGE>
 
have received (in the case of the Trustee, at its Corporate Trust Office)
written notice thereof from the Company or from the holder of any Senior
Indebtedness or from the trustee for or representative of any such holder,
together with proof satisfactory to the Trustee of such holding of Senior
Indebtedness or of the authority of such trustee or representative; provided,
however, that if at least two Business Days prior to the date upon which by the
terms hereof any such moneys may become payable for any purpose (including,
without limitation, the payment of either the principal of (or premium, if any)
or interest, if any, on any Security) the Trustee shall not have received with
respect to such moneys the notice provided for in this Section 1606, then,
anything herein contained to the contrary notwithstanding, the Trustee shall
have full power and authority to receive such moneys and to apply the same to
the purpose for which they were 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. 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
Indebtedness (or a trustee on behalf of such holder) to establish that such a
notice has been given by a holder of Senior Indebtedness or a trustee on behalf
of or a representative of any such holder. 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 Indebtedness (or a trustee on behalf
of or representative of such holder) to participate in any payment or
distribution pursuant to this Article Sixteen, the Trustee may request such
Person to furnish evidence to the reasonable satisfaction of the Trustee as to
the amount of Senior Indebtedness held by such Person (or the amount of Senior
Indebtedness as to which such Person is trustee or representative), the extent
to which such Person is entitled to participate in such payment or distribution
and any other facts pertinent to the rights of such Person under this Article
Sixteen 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 1607.   Trustee as Holder of Senior Indebtedness.

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

     Nothing in this Article Sixteen shall apply to claims of, or payments to,
the Trustee under or pursuant to Section 606.

     Section 1608.   Modifications of Terms of Senior Indebtedness.

     Any renewal or extension of the time of payment of any Senior Indebtedness
or the exercise by the holders of Senior Indebtedness of any of their rights
under any instrument creating or evidencing Senior Indebtedness, including,
without limitation, the waiver of default thereunder, may be made or done all
without notice to or assent from the Holders of the Securities or the Trustee.

                                      84
<PAGE>
 
     No compromise, alteration, amendment, modification, extension, renewal or
other change of, or waiver, consent or other action in respect of, any liability
or obligation under or in respect of, or of any of the terms, covenants or
conditions of any indenture or other instrument under which any Senior
Indebtedness is outstanding or of such Senior Indebtedness, whether or not such
action is in accordance with the provisions of any applicable document, shall in
any way alter or affect any of the provisions of this Article Sixteen or of the
Securities relating to the subordination thereof.

     Section 1609.   Reliance on Judicial Order or Certificate of Liquidating 
                     Agent.

     Upon any payment or distribution of assets of the Company referred to in
this Article Sixteen, 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 insolvency,
bankruptcy, receivership, liquidation, reorganization, dissolution, winding up
or similar case or proceeding is pending, or a certificate of the trustee in
bankruptcy, liquidating trustee, custodian, receiver, 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 Senior Indebtedness 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
Sixteen.

Ladies/Gentlemen:
 
  I am Senior Vice President and General Counsel of Dominion Resources, Inc., a
Virginia corporation ("Dominion Resources"), and I have advised Dominion
Resources in connection with the registration, pursuant to a Registration
Statement (the Registration Statement) on Form S-3 being filed with the
Securities and Exchange Commission under the Securities Act of 1933, to be
offered from time to time by Dominion Resources of up to $950,000,000 of
Dominion Resources's Debt Securities, Preferred Stock, and Common Stock,
without par value, (collectively, the "Offered Securities"), on terms to be
determined at the time of the offering.
 
  In connection with the filing of the Registration Statement, you have
requested my opinion concerning certain corporate matters.
 
  When the terms of any class or series of the Offered Securities have been
authorized by appropriate action of Dominion Resources and have been issued and
sold as described in the Registration Statement, the Prospectus and the
applicable Prospectus Supplement and, with respect to the Debt Securities, such
Debt Securities have been duly executed, authenticated and delivered in
accordance with the applicable indenture or supplemental indenture, then (i)
the Offered Securities will be legally issued and, with respect to shares of
Common Stock and Preferred Stock, fully paid and nonassessable and (ii) the
Debt Securities will be validly authorized and issued and binding obligations
of Dominion Resources.
 
  I hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to me in the Prospectus included
therein under the caption Legal Opinions. In giving this consent, I do not
thereby admit that I am within the category of persons where consent is
required under Section 7 of the Act and the rules and regulations thereunder.
 
                                          Very truly yours,
