                  SUBJECT TO COMPLETION, DATED APRIL 26, 1996

                         SOUTHERN NATIONAL CORPORATION
                                DEBT SECURITIES

     Southern National Corporation (the "Company" or "SNC") may offer from time
to time pursuant hereto up to $1,000,000,000 aggregate principal amount (or, at
the option of the Company if so specified in the applicable prospectus
supplement or prospectus supplements to this Prospectus (each, a "Prospectus
Supplement"), the equivalent thereof in any other currency or currency unit such
as the European Currency Unit), of its unsecured debt securities (the "Debt
Securities") consisting of unsecured senior debt securities (the "Senior Debt
Securities") and/or unsecured subordinated debt securities (the "Subordinated
Debt Securities"). The Debt Securities may be offered as separate series in
amounts, at maturities, at prices and on terms to be determined at the time of
sale as set forth in a Prospectus Supplement or Prospectus Supplements. Although
the aggregate initial offering price of the Debt Securities is limited as set
forth above, the respective indentures pursuant to which the Senior Debt
Securities and the Subordinated Debt Securities are to be issued do not contain
any limitation on the aggregate principal amount of the debt securities covered
thereby. The Senior Debt Securities when issued will rank on a parity with all
other unsecured and unsubordinated indebtedness of the Company, and the
Subordinated Debt Securities when issued will be subordinated as described
herein under "Subordinated Debt Securities -- Subordination".

     When a particular series of Debt Securities is offered, a Prospectus
Supplement or Prospectus Supplements will be delivered setting forth the terms
of such Debt Securities, including the specific designation, aggregate principal
amount, the currency or currency unit in which payments are to be made,
denominations, maturity, premium, if any, rate (which may be fixed or variable)
and time of payment of interest, if any, terms for redemption at the option of
the Company or the holder, if any, terms for sinking fund payments, if any,
subordination terms, if any, and any other terms of such Debt Securities or
otherwise in connection with the offering and sale of the Debt Securities in
respect of which the Prospectus Supplement or Prospectus Supplements are being
delivered. In addition, the Prospectus Supplement or Prospectus Supplements will
set forth the initial public offering price, the names of any underwriters or
agents, the principal amounts, if any, to be purchased by underwriters, the
compensation of such underwriters and agents, if any, and the net proceeds to
the Company. The Debt Securities may be issued in definitive or permanent global
form.

     The Company may sell Debt Securities to or through underwriters acting as
principals for their own account or as agents, and also may sell Debt Securities
directly to other purchasers or through agents designated from time to time. If
the Company, directly or through agents, solicits offers to purchase the Debt
Securities, the Company reserves the sole right to accept and, together with its
agents, to reject in whole or in part any proposed purchase of Debt Securities.
See "Plan of Distribution". Any underwriters, dealers or agents participating in
the offering may be deemed "underwriters" within the meaning of the Securities
Act of 1933 (as amended, the "Securities Act"). See "Plan of Distribution" for
possible indemnification arrangements for underwriters, agents and their
controlling persons.

     This Prospectus may not be used to consummate the sale of Debt Securities
unless accompanied by a Prospectus Supplement.

     THE DEBT SECURITIES WILL BE UNSECURED OBLIGATIONS OF THE COMPANY AND WILL
NOT BE OBLIGATIONS OF A BANK INSURED BY THE FEDERAL DEPOSIT INSURANCE
CORPORATION OR ANY OTHER GOVERNMENT AGENCY.

         THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE
          SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES
           COMMISSION NOR HAS THE SECURITIES AND EXCHANGE COMMISSION
              OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
                 ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY
                       REPRESENTATION TO THE CONTRARY IS
                              A CRIMINAL OFFENSE.

     The Company is a multi-bank holding company headquartered in Winston-Salem,
North Carolina. It conducts its operations in North Carolina, South Carolina and
Virginia primarily through its commercial banking subsidiaries and, to a lesser
extent, through its other subsidiaries. Substantially all of the Company's loans
are to businesses and individuals in the Carolinas and Virginia. The Company has
no material amount of foreign loans and no loans that can be defined as highly-
leveraged transactions. The principal assets of the Company are all of the
outstanding shares of common and preferred stock of Branch Banking and Trust
Company ("BB&T-NC"); BB&T Financial Corporation of South Carolina ("BB&T
Financial-SC"), which in turn owns all the outstanding shares of Branch Banking
and Trust Company of South Carolina ("BB&T-SC"); and BB&T Financial Corporation
of Virginia, which in turn owns all the outstanding shares of Commerce Bank
("Commerce"), located in Virginia Beach, Virginia. At December 31, 1995, the
Company had assets of $20.5 billion, deposits of $14.7 billion, loans of $13.8
billion and shareholders' equity of $1.7 billion. At December 31, 1995, the
Company ranked thirty-fifth among bank holding companies in the United States in
terms of assets and thirty-fourth in terms of deposits.

     The Company and BB&T Financial Corporation (the former parent of BB&T-NC

and the combined bank holding company operates 317 banking offices throughout
North Carolina, South Carolina and Virginia. BB&T-NC, the Company's largest
subsidiary, is the oldest bank in North Carolina. At December 31, 1995, BB&T-NC
had assets of $16.0 billion, deposits of $11.5 billion, loans of $10.6 billion
and shareholders' equity of $1.1 billion. At December 31, 1995, BB&T-NC ranked

local market for retail and commercial customers, including small and mid-size
businesses, public agencies and local governments, trust customers and
individuals. BB&T Leasing Corp., a wholly owned subsidiary of BB&T-NC, offers
lease financing to commercial businesses and municipal governments. BB&T
Investment Services, Inc., a wholly owned subsidiary of BB&T-NC, offers
customers investment alternatives, including discount brokerage services, fixed-
rate and variable-rate annuities, mutual funds and municipal and other
government bonds. BB&T-NC has numerous additional subsidiaries, including BB&T
Insurance Services, Inc., which offers credit life, credit accident and health,
life, and property and casualty insurance on an agency basis; Goddard Technology
Corporation, which engages in the design and production of imaging and security
devices and programs; and Prime Rate Premium Finance Corporation, Inc., which

the Carolinas.

     BB&T-SC serves South Carolina through 103 banking offices. BB&T-SC focuses
on providing a wide range of banking services in its local market for retail and
commercial customers, including small and mid-size businesses, public agencies,
local governments, trust customers and individuals. BB&T-SC's subsidiaries
include BB&T Investment Services of South Carolina, Inc., which is licensed as a
general broker/dealer of securities and is currently engaged in retailing of
mutual funds, U.S. Government securities, municipal securities, fixed and
variable insurance annuity products and unit investment trusts. At December 31,

$2.7 billion and shareholders' equity of $360.3 million. At December 31, 1995,

     Commerce was acquired by the Company on January 10, 1995 and operates 21
banking offices in the Hampton Roads region of southeastern Virginia. Commerce
offers a full range of commercial and retail banking services and provides the
Company with a strong initial presence in a Virginia market contiguous with the
Company's North Carolina market. At December 31, 1995, Commerce had assets of
$737.5 million, deposits of $669.0 million, loans of $505.8 million and

                                USE OF PROCEEDS

     The Company currently intends to use the net proceeds from the sale of any
Debt Securities for general corporate purposes, which may include the reduction
of other indebtedness of the Company, investments at the holding company level,
investments in, or extensions of credit to, its banking and other subsidiaries,
possible acquisitions, stock repurchases and such other purposes as may be
stated in any Prospectus Supplement. Pending such use, the net proceeds may be
temporarily invested or used to reduce short-term indebtedness. The precise
amounts and timing of the application of proceeds will depend upon the funding
requirements of the Company and its subsidiaries and the availability of other
funds. Except as may be described in any Prospectus Supplement, specific
allocations of the proceeds to such purposes will not have been made at the date
of such Prospectus Supplement. If the Company elects at the time of issuance of
Debt Securities to make a different use of the proceeds other than as set forth
herein, such use will be described in the applicable Prospectus Supplement.

     Based upon the historical and anticipated future growth of the Company and
the financial needs of the Company and its subsidiaries, the Company may engage
in additional financings of a character and amount to be determined as the need
arises.

               CONSOLIDATED RATIOS OF EARNINGS TO FIXED CHARGES

     The following are the Company's consolidated ratios of earnings to fixed
charges for the periods indicated:

Earnings to fixed charges:

     Excluding interest on deposits .......  2.02x  3.46x  3.28x  4.12x  2.90x

     Including interest on deposits .......  1.32   1.61   1.38   1.39   1.22
</TABLE>

     For purposes of computing these ratios, earnings represent income from
continuing operations before extraordinary items and cumulative effects of
changes in accounting principles plus income taxes and fixed charges (excluding
capitalized interest). Fixed charges, excluding interest on deposits, represent
interest (other than on deposits, but including capitalized interest), one-third
(the proportion representative of the interest factor) of rents and all
amortization of debt issuance costs. Fixed charges, including interest on
deposits, represent all interest, one-third (the proportion representative of
the interest factor) of rents and all amortization of debt issuance costs.

                       CERTAIN REGULATORY CONSIDERATIONS

GENERAL

     As a bank holding company, the Company is subject to regulation under the
Bank Holding Company Act of 1956 (as amended, the "BHCA") and its examination
and reporting requirements. Under the BHCA, bank holding companies may not
directly or indirectly acquire the ownership or control of more than five
percent of the voting shares or substantially all of the assets of any company,
including a bank, without the prior approval of the Board of Governors of the
Federal Reserve System (the "Federal Reserve Board"). In addition, subject to
certain exceptions, bank holding companies are generally prohibited under the
BHCA from engaging in nonbanking activities, unless such activities are so
closely related to banking or managing and controlling banks as to be a proper
incident thereto.

     In addition, BB&T-NC, BB&T-SC and Commerce (collectively, the "Banks") are
extensively regulated under state and federal law. As state-chartered commercial
banks, the Banks are subject to regulation, supervision and examination by state
banking authorities in their respective home states, including the North
Carolina

                                       4
<PAGE>
 
Commissioner, in the case of BB&T-NC, the South Carolina Commissioner, in the
case of BB&T-SC, and the Virginia State Corporation Commission, Bureau of
Financial Institutions, in the case of Commerce. As federally-insured, nonmember
banks, each of the Banks is also subject to regulation, supervision and
examination by the Federal Deposit Insurance Corporation (the "FDIC").

     The earnings of the Company's subsidiaries, and therefore the earnings of
the Company, are affected by general economic conditions, management policies
and the legislative and governmental actions of various regulatory authorities,
including those referred to above. In addition, there are numerous governmental
requirements and regulations which affect the activities of the Company and its
subsidiaries.

     The following description summarizes some of the state and federal laws to
which the Company and the Banks are subject. To the extent statutory or
regulatory provisions or proposals are described, the description is qualified
in its entirety by reference to the particular statutory or regulatory
provisions or proposals.

PAYMENT OF DIVIDENDS

     The Company is a legal entity separate and distinct from its banking and
other subsidiaries. A major portion of the revenues of the Company result from
amounts paid as dividends to the Company by its bank subsidiaries. The Company's
banking subsidiaries are subject to state laws and regulations that limit the
amount of dividends they can pay. The Company does not expect that these laws
and regulations will materially impact the ability of its banking subsidiaries
to pay dividends. During the year ended December 31, 1995, the Banks paid $88.0
million in cash dividends to the Company. During the first quarter of 1996, the
Banks paid $161.0 million in cash dividends to the Company, including $125.0 
million paid as a special dividend to the Company in order to finance
repurchases of the Company's Common Stock.

     In addition, both the Company and the Banks are subject to various general
regulatory policies and requirements relating to the payment of dividends,
including requirements to maintain adequate capital above regulatory minimums.
The appropriate federal or state regulatory authority is authorized to determine
under certain circumstances relating to the financial condition of a bank or
bank holding company that the payment of dividends would be an unsafe or unsound
practice and to prohibit payment thereof. The Federal Reserve Board, which
regulates the activities of the Company and BB&T Financial-SC, has indicated
that dividends should generally be paid only out of current operating earnings.

CAPITAL

     The Company. The minimum requirement for a bank holding company's ratio of
capital to risk-weighted assets (including certain off-balance-sheet activities,
such as standby letters of credit) is eight percent. At least half of the total
capital is to be composed of common equity, retained earnings and qualifying
perpetual preferred stock, less certain intangibles ("Tier 1 capital"). The
remainder may consist of subordinated debt, qualifying preferred stock and a
limited amount of the loan loss allowance ("Tier 2 capital" and, together with
Tier 1 capital, "total capital"). At December 31, 1995, the Company's Tier 1 and
total capital ratios were 13.0 percent and 14.3 percent, respectively.

     In addition, the Federal Reserve Board has established minimum leverage
ratio requirements for bank holding companies. These requirements provide for a
minimum leverage ratio of Tier 1 capital to adjusted average quarterly assets
("leverage ratio") equal to 3 percent for bank holding companies that meet
certain specified criteria, including that they have the highest regulatory
rating. All other bank holding companies will generally be required to maintain
a leverage ratio of at least 4 to 5 percent. The Company's leverage ratio at
December 31, 1995, was 7.8 percent. The requirements also provide that bank
holding companies experiencing internal growth or making acquisitions will be
expected to maintain strong capital positions substantially above the minimum
supervisory levels without significant reliance on intangible assets.
Furthermore, the requirements indicate that the Federal Reserve Board will
continue to consider a "tangible Tier 1 leverage ratio" (deducting all
intangibles) in evaluating proposals for expansion or new activity.

     The Banks. The FDIC has adopted minimum risk-based and leverage ratio
guidelines to which the Banks are subject. Under the risk-based capital
requirements of the FDIC, each of the Banks is required to maintain a minimum
ratio of total capital (Tier 1 plus Tier 2 capital) to total risk-adjusted
assets (which include the credit risk equivalents of certain off-balance sheet
items) of 8 percent, of which half (4 percent) must be Tier 1 capital. In
addition, the FDIC requires a minimum leverage ratio (Tier 1 capital to average
total consolidated assets) of 3 percent. These risk-based capital and leverage
ratios are minimum supervisory ratios generally applicable to banks that meet
certain specified criteria, including that they have one of the two highest
regulatory ratings. Banking institutions not meeting these criteria are expected
to operate with capital positions well above the minimum ratios. In addition,
the FDIC may set capital requirements for a particular bank that are higher than
the minimum ratios when circumstances warrant.

     The FDIC's risk-based capital standards explicitly identify concentrations
of credit risk and the risk arising from non-traditional activities, as well as
an institution's ability to manage these risks, as important factors to be taken
into account by the agency in assessing an institution's overall capital
adequacy. The capital regulations also provide that an institution's exposure to
a decline in the economic value of its capital due to changes in interest rates
be considered by the agency as a factor in evaluating a bank's capital adequacy.
The banking agencies issued for comment a proposed joint policy statement that
describes the process the banking agencies will use to measure and assess the
exposure of a bank's net economic value to changes in interest rates. The
agencies may, ultimately, establish an explicit capital charge for interest rate
risk.

     Under federal banking laws, failure to meet the minimum regulatory capital
requirements could subject a banking institution to a variety of enforcement
remedies available to federal regulatory authorities, including, in the most
severe cases, the termination of deposit insurance by the FDIC and placing the
institution into conservatorship or receivership.

     The capital ratios of each of the Banks exceeded all minimum regulatory
capital requirements as of December 31, 1995. As of December 31, 1995, the ratio
of total capital to total risk-adjusted assets for BB&T-NC, BB&T-SC and Commerce
were 11.6%, 15.3% and 12.5%, respectively, and the Banks' leverage ratios (Tier
1 capital to average total consolidated assets) were 6.4%, 9.0% and 8.2%,
respectively.

FIRREA

     The Financial Institutions Reform, Recovery and Enforcement Act of 1989
("FIRREA"), among other things, imposes liability on an institution the deposits
of which are insured by the FDIC, such as the Banks, for certain potential
obligations to the FDIC incurred in connection with other FDIC-insured
institutions under common control with such institution.

     Under Federal Reserve Board policy, the Company is expected to act as a
source of financial strength to each of the Banks and to commit resources to
support each of such subsidiaries. This support may be required at times when,
absent such Federal Reserve Board policy, the Company may not find itself able
to provide it.

     Any capital loans by a bank holding company to any of its subsidiary banks
are subordinate in right of payment to deposits and to certain other
indebtedness of such subsidiary banks. In the event of a bank holding company's
bankruptcy, any commitment by the bank holding company to a federal bank
regulatory agency to maintain the capital of a subsidiary bank will be assumed
by the bankruptcy trustee and entitled to a priority of payment.

PROMPT CORRECTIVE ACTION UNDER FDICIA

     The prompt corrective action provisions of the Federal Deposit Insurance
Company Improvement Act of 1991 ("FDICIA") significantly expanded the regulatory
and enforcement powers of federal banking regulators, including the FDIC. Among
other things, FDICIA establishes additional capital standards for insured
depository

                                       6
<PAGE>
 
institutions and requires specific enforcement actions by the appropriate
federal regulatory agencies against institutions that fail to meet these
standards. The extent of these powers depends upon whether the institutions in
question are "well capitalized," "adequately capitalized," "undercapitalized,"
"significantly undercapitalized" or "critically undercapitalized."

     The FDIC's regulations establish specific actions that are permitted or, in
certain cases, required to be taken by regulators with respect to institutions
falling within one of the three undercapitalized categories. Depending on the
level of an institution's capital, the agency's corrective powers can include:
requiring a capital restoration plan; placing limits on asset growth and
restrictions on activities; requiring the institution to issue additional stock
(including voting stock) or to be acquired; placing restrictions on transactions
with affiliates; restricting the interest rate the institution may pay on
deposits; ordering a new election for the institution's board of directors;
requiring that certain senior executive officers or directors be dismissed;
prohibiting the institution from accepting deposits from correspondent banks;
requiring the institution to divest certain subsidiaries; prohibiting the
payment of principal or interest on subordinated debt; prohibiting the holding
company from making capital distributions without prior regulatory approval;
and, in the most severe cases, appointing a receiver for the institution. A bank
that is undercapitalized is required to submit a capital restoration plan, and
such a plan will not be accepted unless, among other things, the bank holding
company guarantees the capital plan, up to a certain specified amount. Under
certain circumstances, a "well capitalized," "adequately capitalized" or
"undercapitalized" institution may be required to comply with restrictions
applicable to the next lowest capital category.

     As of December 31, 1995, the Company and each of the Banks were classified
as "well capitalized."

CONSERVATORSHIP AND RECEIVERSHIP POWERS OF THE FEDERAL AND STATE BANKING
AGENCIES

     The federal banking agencies have broad enforcement powers over depository
institutions, including the power to terminate deposit insurance, impose
substantial fines and other civil penalties and to appoint a conservator or
receiver. Certain federal statutes to which the Company and its subsidiaries are
subject also contain criminal penalties. In addition to the grounds discussed
under "Prompt Corrective Action Under FDICIA," the FDIC may appoint itself as
conservator or receiver for each of the Banks if any one or more of a number of
circumstances exist, including, without limitation, the fact that the bank is
undercapitalized and has no reasonable prospect of becoming adequately
capitalized; fails to become adequately capitalized when required to do so;
fails to submit a timely and acceptable capital restoration plan; or materially
fails to implement an accepted capital restoration plan.

     State regulatory authorities have broad enforcement powers over state
banking institutions chartered in each of their states including powers to
impose fines and other civil penalties and to appoint a conservator (with the
approval of the Governor in the case of North Carolina) in order to conserve the
assets of any such institution for the benefit of depositors and other creditors
thereof. The state statutes to which the Company and its subsidiaries are
subject also contain criminal penalties. In addition, the North Carolina
Commissioner has the authority to take possession of a state bank in certain
circumstances, including, among other things, when it appears that such bank has
violated its charter or any applicable laws or is conducting its business in an
unauthorized or unsafe manner, or is in an unsafe or unsound condition to
transact its business or has an impairment of its capital stock. A conservator
has the authority, under the direction of the applicable state authority to take
possession of the books, records and assets of a bank and to exercise all powers
of such state authority in order to preserve the assets of such bank.

     The FDIC may provide federal assistance to a "troubled institution" without
placing the institution into conservatorship or receivership. In such a case,
preexisting debtholders and shareholders may be required to make substantial
concessions and, insofar as practical, the FDIC will succeed to their interests
in proportion to the amount of federal assistance provided.

                                       7

INSOLVENCY, LIQUIDATION OR OTHER DEFAULT BY THE BANKS

     In the event of the liquidation or other resolution of any federally-
insured depository institution, such as each of the Banks, the claims of
depositors of such an institution (including claims by the FDIC as subrogee of
insured depositors) and administrative expenses of the receiver are entitled to
priority in payment over the claims of any other senior or general creditors of
the institution, other than secured creditors. A substantial majority of the
liabilities of each of the Banks are deposits or secured liabilities.

     A depository institution insured by the FDIC can be held liable for any
loss incurred by, or reasonably expected to be incurred by, the FDIC in
connection with (i) the default of a commonly-controlled depository institution
or (ii) any assistance provided by the FDIC to a commonly-controlled depository
institution in danger of default. However, such liability to the FDIC would be
subordinated in right of payment to deposit liabilities and to most secured,
senior, general or subordinated obligations, other than obligations owed to any
affiliate of the depository institution (with certain exceptions) and any
obligations to shareholders of such depository institution in their capacity as
such.

     As conservator or receiver for an insured depository institution, and in
order to promote the orderly administration of the institution's affairs, the
FDIC may disaffirm or repudiate any contract or lease to which such institution
is a party. The FDIC as conservator or receiver is also permitted to enforce
most types of contracts pursuant to their terms notwithstanding any acceleration
provisions therein, and may transfer to a new obligor any of the institution's
assets and liabilities, without approval or consent of the institution's
creditors. Pursuant to FDICIA, the FDIC is also authorized to settle all
uninsured and unsecured claims in the insolvency of an insured bank by making a
final settlement payment at a percentage rate reflecting an average of the
FDIC's receivership recovery experience and constituting full payment and
disposition of the FDIC's obligations to such uninsured and unsecured claimants.

     Should a state regulatory authority elect to take possession of any bank
for the purpose of liquidation, administrative claims and claims of depositors
are entitled to priority in payment over the claims of creditors. Each of the
state authorities may appoint the FDIC as its agent for the purpose of
liquidation of a bank, provided that the liabilities of such bank to its
depositors are insured by the FDIC.

     If the FDIC or state regulatory agency were appointed receiver of a bank,
the amount paid on claims in respect of the bank's obligations to its creditors
would depend upon, among other factors, the amount of assets in the receivership
and the relative priority of the claim.

DEPOSIT INSURANCE ASSESSMENTS

     The deposits of each of the Banks are insured by the FDIC, up to applicable
limits. Most of the deposits of the Banks are subject to deposit premium
assessments of the Bank Insurance Fund ("BIF") of the FDIC. In addition,
approximately 40 percent of the Banks' deposits (which are related to the
acquisition of thrift deposits) is subject to assessments by the Savings
Association Insurance Fund ("SAIF") of the FDIC. Under the FDIC's risk-based
insurance system, BIF-assessed deposits are currently subject to premiums of
between $.00 and $.27 per $100 of deposits, depending upon the institution's
capital position and other supervisory factors. The current premiums reflect a
reduction, effective January 1, 1996, from a range of $.04 to $.31 per $100 of
deposits. The rate applicable to the BIF-assessed deposits of each of the Banks
is currently $.00 per $100 of eligible deposits, with a minimum semiannual
assessment of $1,000. The range of premiums applicable to SAIF-assessed deposits
is between $.23 and $.31 per $100 of deposits, and the assessment rate for each
of the Banks' SAIF-assessed deposits is $.23 per $100 of eligible deposits.

     Proposed budget reconciliation legislation that contains provisions to
recapitalize the SAIF was passed by both houses of Congress and reconciled in
conference committee. However, the President vetoed the proposed

                                       8
<PAGE>
 
budget reconciliation legislation on December 6, 1995, for reasons unrelated to
the SAIF recapitalization issue. The vetoed legislation included provisions for
a one-time special assessment, as determined by the FDIC, on SAIF-assessable
deposits of insured depository institutions in an amount adequate to cause the
SAIF to achieve its specific designated reserve ratio of 1.25 percent (which
would have called for a special assessment in the range of $.80 per $100 of 
SAIF-assessable deposits).

     Under the vetoed legislation, the special assessment would have been
applied to the amount of SAIF-assessable deposits held as of March 31, 1995.
(The actual cut-off date in any final legislation cannot be determined with
certainty at this time.) The SAIF-assessable deposits of BB&T-NC and BB&T-SC as
of March 31, 1995 totaled approximately $4.1 billion and $1.5 billion,
respectively. Under the vetoed legislation, BB&T-NC would have received a 20
percent discount on the assessment, because the bank's SAIF-assessable deposits
were less than 50 percent of its total assessable deposits as of June 30, 1995.
The pre-tax impact on the Company of a one-time assessment of the type included
in the vetoed legislation would not be expected to exceed $41 million. The
Company expects to record this expense following the enactment of any such
legislation. In the event that the SAIF is recapitalized pursuant to any such
legislation, it is expected that future assessment rates applicable to
SAIF-assessable deposits would be reduced.

     The vetoed legislation contains additional provisions that, among other
things, would require BIF-member institutions to share pro rata in the
obligations of SAIF members for certain government bonds.

     Although the SAIF-recapitalization provisions discussed in the preceding
paragraphs were included in legislation that was vetoed and therefore have not
been enacted into law, similar provisions are still being discussed and may be
included in other proposed legislation. The final form of the proposed
legislation, including whether the legislation will contain some or all of the
provisions discussed above, cannot be determined with certainty at this time.
Similarly, the date of passage of the final form of any such legislation, or
whether this or any such legislation will be passed during this session of
Congress, cannot be determined with certainty at this time.

     Under the federal banking laws, a federally-insured institution is
prohibited from paying interest on its capital notes or debentures (if such
interest is required to be paid only out of net profits) or distributing any of
its capital assets while it remains in default in the payment of any assessment
due to the FDIC.

SAFETY AND SOUNDNESS STANDARDS

     Effective August 9, 1995, the federal banking agencies published final
agency guidelines that establish safety and soundness standards addressing
operational and managerial, including compensation matters for certain insured
financial institutions, as required by FDICIA. Banks failing to meet these
standards are required to submit compliance plans to their appropriate federal
regulators. On this same date, the agencies issued for comment proposed
guidelines regarding asset quality and earnings standards for insured
institutions.

INTERSTATE BANKING AND BRANCHING LEGISLATION

     The Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994
("IBBEA") authorizes interstate acquisitions of banks and bank holding companies
without geographic limitation. In addition, beginning June 1, 1997, IBBEA
authorizes a bank to merge with a bank in another state as long as neither of
the states has opted out of interstate branching between the date of enactment
of IBBEA and May 31, 1997. IBBEA further provides that states may enact laws
permitting interstate bank merger transactions prior to June 1, 1997. A bank may
establish and operate a de novo branch in a state in which the bank does not
maintain a branch if that state expressly permits de novo branching. Once a bank
has established branches in a state through an interstate merger transaction,
the bank may establish and acquire additional branches at any location in the
state where any bank involved in the interstate merger transaction could have
established or acquired branches under applicable federal or state law. A bank
that has established a branch in a state through de novo branching may establish
and acquire additional branches in such state in the same manner and to the same
extent as a bank having a branch in such state as a result of an interstate
merger. If a state opts out of interstate branching within the specified time
period, no bank in any other state may establish a branch in the opting out
state, whether through an acquisition or de novo.

                                       9
<PAGE>
 
     The North Carolina law permits de novo branching on a reciprocal basis
until June 1, 1997, and unrestricted de novo branching thereafter. Virginia has
enacted an early opt-in law permitting interstate bank merger transactions
effective July 1, 1995. The Virginia law permits de novo branching on a
reciprocal basis. At this time, South Carolina has not enacted an early opt-in
law.

                      DESCRIPTION OF THE DEBT SECURITIES

     The Debt Securities will constitute either Senior Debt Securities or
Subordinated Debt Securities. The Senior Debt Securities will be issued under a
senior indenture (the "Senior Indenture"), between the Company and
_______________, as senior trustee (the "Senior Trustee"). The Subordinated Debt
Securities will be issued under a subordinated indenture (the "Subordinated
Indenture"), between the Company and ____________, as subordinated trustee (the
"Subordinated Trustee"). The Senior Indenture and the Subordinated Indenture
collectively are referred to as the "Indentures" and the Senior Trustee and the
Subordinated Trustee collectively are referred to as the "Trustee."

     In the event of the resignation or removal of the Trustee prior to the
issuance of a particular series of Debt Securities, the trustee for such series
of Debt Securities will be identified in the Prospectus Supplement for such
series, and all references to "Trustee" shall be deemed to mean the trustee so
identified. No Trustee shall be responsible for the acts, obligations,
liabilities or responsibilities of any other trustee. The following summaries of
certain provisions of the Indentures do not purport to be complete and are
subject to, and are qualified in their entirety by reference to, all the
provisions of the Indentures, including the definitions therein of certain
terms. Wherever particular sections or defined terms of the Indentures are
referred to, it is intended that such sections or definitions shall be
incorporated herein by reference. The following sets forth certain terms and
provisions of the Debt Securities to which any Prospectus Supplement may relate.
The particular terms of the Debt Securities offered by any Prospectus Supplement
(the "Offered Securities") and the extent, if any, to which such general
provisions may apply to the Debt Securities so offered, will be described in the
Prospectus Supplement relating to such Offered Securities.

GENERAL

     The Indentures do not limit the aggregate principal amount of Debt
Securities that may be issued thereunder and provide that Debt Securities may be
issued from time to time in one or more series. The Debt Securities will be
direct, unsecured obligations of the Company and will not be obligations of a
bank insured by the FDIC or any other government agency. Neither the Indentures
nor the Debt Securities will limit or otherwise restrict the amount of other
indebtedness that may be incurred or other securities that may be issued by the
Company or any of its subsidiaries.

     Reference is made to the Prospectus Supplement relating to the particular
series of Offered Securities for the following terms of such Offered Securities:
(1) the title; (2) any limit on the aggregate principal amount; (3) whether such
Offered Securities are Senior Debt Securities or Subordinated Debt Securities;
(4) the price or prices (expressed as a percentage of the aggregate principal
amount thereof) at which such Offered Securities will be issued; (5) the date or
dates on which such Offered Securities will mature; (6) the rate or rates (which
may be fixed or floating) per year at which such Offered Securities will bear
interest, if any, or the method of determining the same; (7) the date from which
such interest, if any, on such Offered Securities will accrue, the dates on
which such interest, if any, will be payable, the date on which payment of such
interest, if any, will commence and the Regular Record Dates for such Interest
Payment Dates, if any; (8) the extent to which any of such Offered Securities
will be issuable in the form of one or more temporary or permanent Global
Securities, and if so, the identity of the Depositary for such Global
Securities, or the manner in which any interest payable on temporary or
permanent Global Securities will be paid; (9) the dates, if any, on which, and
the price or prices at which, such Offered Securities will, pursuant to any
mandatory sinking fund provisions, or may, pursuant to any optional sinking fund
or to any purchase fund provisions, be redeemed by the Company, and the other
detailed terms and provisions of such sinking and/or purchase funds; (10) the
date, if any, after which, and the price or prices at which, such Offered
Securities may, pursuant to an optional redemption provision, be redeemed at the
option of the Company or of the holder thereof and the other detailed terms and
provisions of such optional redemption; (11) the denomination or denominations
in which such Offered Securities are authorized to be issued; (12) whether such
Offered Securities will be issued as Registered Securities, Bearer Securities,
or both and any limitations on the issuance of such Bearer Securities (including
exchange for Registered Securities of the same series);

                                       10
<PAGE>
 
(13) information with respect to book-entry procedures; (14) each office or
agency where, subject to the terms of the applicable Indenture, such Offered
Securities may be presented for registration of transfer or exchange; and (15)
any other terms of such Offered Securities (which will not be inconsistent with
the provisions of the applicable Indenture).

     Debt Securities may be issued as Original Issue Discount Securities to be
sold at a substantial discount below their principal amount. Special federal
income tax and other considerations relating thereto will be described in the
applicable Prospectus Supplement.

     The Debt Securities may be issuable as Registered Securities, Bearer
Securities or both. Unless otherwise indicated in the applicable Prospectus
Supplement, each series of Debt Securities will be issued as Registered
Securities. Debt Securities issued as Bearer Securities shall have interest
coupons attached, unless issued as zero coupon securities. Unless otherwise
indicated in the applicable Prospectus Supplement, Registered Securities will be
issued only in denominations of $1,000 or integral multiples thereof and Bearer
Securities will be issued only in denominations of $5,000 or integral multiples
thereof.

     Bearer Securities shall not be offered, sold, resold or delivered in
connection with their original issuance in the United States or to any United
States person (as defined below) other than to offices located outside the
United States of certain United States financial institutions. "United States
person" means any citizen or resident of the United States, any corporation,
partnership or other entity created or organized in or under the laws of the
United States or any estate or trust the income of which is subject to United
States federal income taxation regardless of its source, and "United States"
means the United States of America (including the States and the District of
Columbia) and its possessions. Purchasers of Bearer Securities will be subject
to certification procedures and may be affected by certain limitations under
United States tax laws. Such procedures and limitations will be described in the
Prospectus Supplement relating to the offering of the Bearer Securities.

     The applicable Prospectus Supplement will include a description of the
requirements for certification of ownership by non-United States persons that
will apply prior to (1) the issuance of Bearer Securities or (2) the payment of
interest that occurs prior to the issuance of Bearer Securities.

     Unless otherwise indicated in the applicable Prospectus Supplement,
Registered Securities of any series (other than a Global Security, except as set
forth below) will be exchangeable into an equal aggregate principal amount of
Registered Securities of the same series, tenor and terms of different
authorized denominations and Bearer Securities may be exchanged for Registered
Securities on the terms set forth in the applicable Prospectus Supplement. In no
event will Registered Securities be exchangeable for Bearer Securities. Unless
otherwise indicated in the applicable Prospectus Supplement, Debt Securities may
be presented for exchange, and Registered Securities (other than a Global
Security) may be presented for registration of transfer, at the offices of the
appropriate Trustee. The Company also may designate in the applicable Prospectus
Supplement the corporate trust department of BB&T-NC as an office where the
transfer of the Registered Securities may be registered.

     No service charge will be made for any registration of transfer or exchange
of the Debt Securities, but the Company may require payment sufficient to cover
any tax or other governmental charge payable in connection therewith.

PAYMENT AND PAYING AGENT

     Unless otherwise indicated in the applicable Prospectus Supplement, payment
of principal of and any premium and interest on Registered Securities will be
made at the office of the appropriate Trustee, except that at the option of the
Company interest may be paid by mailing a check to the address of the person
entitled thereto as it appears on the Security Register (Section 3.02 of the
Senior Indenture; Section 4.02 of the Subordinated Indenture). The Company also
may designate in the applicable Prospectus Supplement the corporate trust
department of BB&T-NC, as an office where principal and any premium and interest
on Registered Securities may be paid. Paying Agents will be named in the
Prospectus Supplement and may be terminated at any time.

                                       11
<PAGE>
 
     Unless otherwise indicated in the applicable Prospectus Supplement, payment
of principal of and any premium and interest on Bearer Securities will be made,
subject to applicable laws and regulations, at such paying agencies outside the
United States as the Company may designate from time to time. Any such payment
may be made, at the option of the holder, by check or by transfer to an account
maintained by the payee with a bank located outside the United States. Unless
otherwise indicated in the applicable Prospectus Supplement, payment of interest
on Bearer Securities will be made only against surrender of the coupon relating
to the relevant Interest Payment Date. No payment with respect to any Bearer
Security will be made at any office or agency of the Company 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.

GLOBAL SECURITIES

     The Debt Securities of a series may be issued in whole or in part in the
form of one or more Global Securities that will be deposited with, or on behalf
of, a depositary (the "Depositary") identified in the Prospectus Supplement
relating to such series. Global Securities may be issued in either registered or
bearer form and in either temporary or permanent form. Unless and until it is
exchanged in whole or in part for the individual certificates evidencing the
Debt Securities represented thereby, a Global Security may not be transferred
except as a whole by the Depositary for such Global Security to a nominee of
such Depositary or by a nominee of such Depositary to such Depositary or another
nominee of such Depositary or by such Depositary or any such nominee to a
successor of such Depositary or a nominee of such successor.

     The specific terms of the depositary arrangement with respect to a series
of Debt Securities will be described in the Prospectus Supplement relating to
such series. The Company anticipates that the following provisions will apply to
all depositary arrangements although no assurance can be given that such will be
the case.

     Upon the issuance of a Global Security, the Depositary for such Global
Security or its nominee will credit, on its book-entry registration and transfer
system, the respective principal amounts of the Debt Securities represented by
such Global Security to the accounts of institutions that have accounts with
such Depositary ("participants"). The accounts to be credited shall be
designated by the underwriters or agents of such Debt Securities or by the
Company if such Debt Securities are offered and sold directly by the Company.
Ownership of beneficial interests in a Global Security will be limited to
participants or persons that may hold interests through participants. Ownership
of such beneficial interests will be shown on, and the transfer of that
ownership will be effected only through, records maintained by the Depositary or
its nominee for such Global Security (with respect to interests of participants)
and the records of participants (with respect to persons other than
participants). The laws of some states require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and such laws may impair the ability to transfer beneficial interests in
a Global Security.

     So long as the Depositary for a Global Security, or its nominee, is the
owner of such Global Security, such Depositary or such nominee, as the case may
be, will be considered the sole owner or holder of the Debt Securities
represented by such Global Security for all purposes under the Indenture
governing such Debt Securities. Except as set forth below, owners of beneficial
interest in a Global Security registered in their names will not receive or be
entitled to receive physical delivery of Debt Securities of such series in
definitive form and will not be considered the owners or holders thereof under
the Indenture governing such Debt Securities.

     Payments of principal of and any premium and interest on Debt Securities
registered in the name of or held by a Depositary or its nominee will be made to
the Depositary or its nominee, as the case may be, as the registered owner or
the holder of the Global Security representing such Debt Securities. None of the
Company, the Trustee for such Debt Securities or any Paying Agent or the
registrar for such Debt Securities will have any responsibility or liability for
any aspect of the records relating to or payments made on account of beneficial
ownership interests in a Global Security for such Debt Securities or for
maintaining, supervising or reviewing any records relating to or payments made
on account of beneficial ownership interests in a Global Security or for
maintaining, supervising or reviewing any records relating to such beneficial
ownership interests.

                                       12
<PAGE>
 
     The Company expects that the Depositary for Debt Securities of a series,
upon receipt of any payment of principal, premium or interest in respect of a
permanent Global Security, immediately will credit participants' accounts with
payments in amounts proportionate to their respective beneficial interests in
the principal amount of such Global Security as shown on the records of such
Depositary or its nominee. The Company also expects that payments by
participants to owners of beneficial interests in such Global Security held
through such participants will be governed by standing instructions and
customary practices, as is now the case with securities held for the accounts of
customers in bearer form or registered in "street name," and will be the
responsibility of such participants.

     If the Depositary for a series of Debt Securities is at any time unwilling,
unable or ineligible to continue as Depositary and a successor Depositary is not
appointed by the Company within 90 days, the Company will issue Debt Securities
of such series in definitive form in exchange for the Global Security or
Securities representing the Debt Securities of such series. In addition, the
Company at any time and in its sole discretion, subject to any limitations
described in the Prospectus Supplement relating to such Debt Securities, may
determine not to have any Debt Securities of a series represented by one or more
Global Securities and, in such event, will issue Debt Securities of such series
in definitive form in exchange for the Global Security or Securities
representing such Debt Securities. Further, if the Company so specifies with
respect to the Debt Securities of a series, an owner of a beneficial interest in
a Global Security representing Debt Securities of such series may receive, on
terms acceptable to the Company and the Depositary for such Global Security,
Debt Securities of such series in definitive form in exchange for such
beneficial interest, subject to any limitations described in the Prospectus
Supplement relating to such Debt Securities. In any such instance, an owner of a
beneficial interest in a Global Security will be entitled to physical delivery
in definitive form of Debt Securities of the series represented by such Global
Security equal in principal amount to such beneficial interest and to have such
Debt Securities registered in its name (if the Debt Securities of such series
are issuable as Registered Securities). Debt Securities of such series so issued
in definitive form will be issued (a) as Registered Securities in denominations,
unless otherwise specified by the Company, of $1,000 or integral multiples
thereof if the Debt Securities of such series are issuable as Registered
Securities, (b) as Bearer Securities in denominations, unless otherwise
specified by the Company, of $5,000 or integral multiples thereof if the Debt
Securities of such series are issuable as Bearer Securities or (c) as either
Registered or Bearer Securities, if the Debt Securities of such series are
issuable in either form.

CERTAIN COVENANTS OF THE COMPANY

     Limitation on Certain Dispositions and on Merger and Sale of Assets. Except
as described below under "Consolidation, Merger, Sale, Conveyance and Lease,"
each Indenture prohibits the sale or other disposition by the Company of shares
of, or securities convertible into, or options, warrants or rights to subscribe
for or purchase shares of, Voting Stock of a Principal Constituent Bank, the
merger or consolidation of a Principal Constituent Bank with any other
corporation (unless the surviving corporation is the Company or a Controlled
Subsidiary), and the lease, sale or transfer of all or substantially all the
assets of a Principal Constituent Bank to any corporation or Person, except to
the Company or a Controlled Subsidiary or a Person that, upon such lease, sale
or transfer, will become the Company or a Controlled Subsidiary. The Indentures,
however, do not prohibit any such sale, assignment, transfer or disposition of
securities, any such merger or consolidation or any such lease, sale or transfer
of properties and assets if required (i) by law or (ii) as a condition imposed
by law to the acquisition by the Company or any Controlled Subsidiary, directly
or indirectly, of any Person if, thereafter, (a) such person would be a
Controlled Subsidiary; (b) the Consolidated Net Banking Assets of the Company
would not be decreased; and (c) BB&T-NC would still be a Controlled Subsidiary
(Section 3.06 of the Senior Indenture; Section 4.06 of the Subordinated
Indenture). "Controlled Subsidiary" means any Subsidiary of which more than 80%
of the aggregate voting power of the outstanding shares of the Voting Stock is
at the time owned directly or indirectly by the Company or by one or more
Controlled Subsidiaries or by the Company and one or more Controlled
Subsidiaries, after giving effect to the issuance to any Person other than the
Company or any Controlled Subsidiary of Voting Stock of the Subsidiary issuable
on exercise of options, warrants or rights to subscribe for such Voting Stock or
on conversion of securities convertible into such Voting Stock. "Principal
Constituent Bank" means BB&T-NC and, at any time, any other bank subsidiary the
total assets of which (as set forth in the most recent statement of condition of
such bank subsidiary) equal more than 30% of the total assets of all bank
subsidiaries as determined from the most recent statements of condition of the
bank subsidiaries.

                                       13
<PAGE>
 
     Limitation on Creation of Liens. Each Indenture provides that the Company
will not create, assume, incur or suffer to exist any pledge, encumbrance or
lien, as security for indebtedness for borrowed money, upon any shares of, or
securities convertible into, or options, warrants or rights to subscribe for or
purchase shares of, Voting Stock of a Principal Constituent Bank now or
hereafter owned by the Company, directly or indirectly, if, treating the pledge,
encumbrance or lien as a transfer to the secured party, the Principal
Constituent Bank would not be a Controlled Subsidiary (Section 3.07 of the
Senior Indenture; Section 4.07 of the Subordinated Indenture).

     No Other Restrictive Covenants. Neither of the Indentures restricts the
Company from incurring, assuming or becoming liable for any type of debt nor
from creating, assuming, incurring or permitting to exist any mortgage, pledge,
encumbrance, lien or charge on its property (except the Voting Stock of a
Principal Constituent Bank). In addition, the Indentures do not require the
Company to maintain any financial ratios or specified levels of net worth or
liquidity and do not contain any other provisions which would provide protection
to holders of the Debt Securities due to a sudden or dramatic decline in the
credit quality of such Debt Securities caused by a change in control,
recapitalization or other capital restructuring of the Company.

MODIFICATION OF THE INDENTURES; WAIVER OF COVENANTS

     Each Indenture contains provisions permitting the Company and the Trustee
to modify the Indenture with the consent of the holders of not less than a
majority in aggregate principal amount of the outstanding Debt Securities of
each series affected thereby, except that, without the consent of the holder of
each Debt Security affected thereby, no such modification may, among other
things: (a) change the stated maturity date of the principal of or any premium,
or any installment of interest on, any Outstanding Security; (b) reduce the
principal amount of, or any premium or interest on, any Outstanding Security;
(c) reduce the amount of principal of an Original Issue Discount Security
payable upon acceleration of the maturity thereof; (d) change the place of
payment of principal of, or any premium or interest on, any Outstanding
Security; (e) impair the right to institute suit for the enforcement of any
payment on or with respect to any Outstanding Security; (f) reduce the
percentage in principal amount of Outstanding Securities of any series the
consent of whose holders is required for modification or amendment of the
Indenture or for waiver of compliance with certain provisions of the Indenture
or for waiver of certain defaults and their consequences; or (g) in the case of
the Subordinated Indenture, make any change in the subordination provisions that
adversely affects the rights of any holder of Subordinated Debt Securities.

     Prior to any acceleration of the Debt Securities of any series, the holders
of a majority in aggregate principal amount of the outstanding Debt Securities
of such series may waive any past default or Event of Default under the
applicable Indenture, except a default under a covenant that cannot be modified
without the consent of each holder of a Debt Security of the series affected
thereby (Section 4.07(b) of the Senior Indenture; Section 5.07(b) of the
Subordinated Indenture). In addition, the holders of a majority in aggregate
principal amount of the outstanding Debt Securities of any series may rescind a
declaration of acceleration of the Debt Securities of any series before any
judgment has been obtained if (i) the Company pays the Trustee certain amounts
due the Trustee plus all matured installments of principal of and any premium
and interest on the Debt Securities of such series (other than installments due
by acceleration) and interest on the overdue installments to the extent provided
in the applicable Indenture and (ii) all other defaults with respect to Debt
Securities of that series under the applicable Indenture have been cured or
waived (Section 4.01 of the Senior Indenture; Section 5.01 of the Subordinated
Indenture).

CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE

     Each Indenture provides that the Company may not consolidate with or merge
into another corporation, or convey, transfer or lease its properties and assets
substantially as an entirety to any Person unless: (a) the successor is
organized under the laws of any domestic jurisdiction and assumes the Company's
obligations on the Debt Securities and under the applicable Indenture; (b) after
giving effect to the transaction, no Event of Default, and no event which, after
notice or lapse of time or both, would become an Event of Default, has occurred
and is continuing; and (c) certain other conditions are met (Section 9.01 of the
Senior Indenture; Section 10.01 of the Subordinated Indenture). In that event,
the successor will be substituted for the Company and except in the case of a
lease, the Company will be relieved

                                       14
<PAGE>
 
of its obligations under the applicable Indenture and the Debt Securities of
each series (Section 9.02 of the Senior Indenture; Section 10.02 of the
Subordinated Indenture).

THE TRUSTEE

     The Company will have no material relationship with the Trustee other than
as Trustee. Any Principal Constituent Bank may transact business with the
Trustee in the ordinary course.

     The Indenture, under the Trust Indenture Act of 1939, as amended (the
"Trust Indenture Act"), is deemed to contain certain limitations on the right of
the Trustee, as a creditor of the Company, to obtain payment of claims in
certain cases or to realize on certain property received in respect of any such
claim, as security or otherwise. The Trustee will be permitted to engage in
transactions with the Company, provided that such transactions do not result in
a material relationship between the Company and the Trustee. The occurrence of a
default under either Indenture with respect to Subordinated Debt Securities or
Senior Debt Securities could create a conflicting interest for the Trustee under
the Trust Indenture Act. If the default has not been cured or waived within 90
days after the Trustee has or acquires a conflicting interest, the Trustee
generally is required by the Trust Indenture Act to eliminate such conflicting
interest or resign as Trustee with respect to the Senior Debt Securities or the
Subordinated Debt Securities. In the event of the Trustee's resignation, the
Company promptly will appoint a successor trustee with respect to the affected
securities.

                            SENIOR DEBT SECURITIES

     The Senior Debt Securities will be direct, unsecured obligations of the
Company and will rank equally and ratably with all outstanding unsecured and
unsubordinated indebtedness of the Company.

EVENTS OF DEFAULT

     The Senior Indenture defines an Event of Default with respect to any
particular series of Senior Debt Securities as being any one of the following
events unless it is either inapplicable to a particular series or specifically
deleted or modified for the Senior Debt Securities of such series: (a) default
for 30 days in the payment of any interest upon any of the Senior Debt
Securities of that series; (b) default in the payment of the principal of or any
premium on any of the Senior Debt Securities of that series when due; (c)
default in the payment of any sinking fund installment or analogous obligation
with respect to any of the Senior Debt Securities of that series when due; (d) a
default or event of default under any instrument under which there may be issued
or borrowed, or by which there may be secured or evidenced, any indebtedness of
the Company (other than the Senior Debt Securities of such series or
indebtedness to a Subsidiary) or any Subsidiary (other than indebtedness of any
Subsidiary owing to the Company or to another Subsidiary) shall happen and not
less than $1,000,000 of such indebtedness shall be past due, or become due by
acceleration, and such indebtedness or acceleration is not discharged or
rescinded within 15 days after notice by the Senior Trustee or holders of at
least 25% in aggregate principal amount of the outstanding Senior Debt
Securities of that series (calculated in accordance with the formula set forth
in such series in the case of a series of Senior Debt Securities issued as
Original Issue Discount Securities); (e) final judgment(s) or order(s) for the
payment of money in excess of $1,000,000 is entered against the Company or one
or more Principal Constituent Banks and within 90 days of entry is not
discharged or the execution thereof is not stayed pending appeal, or within 90
days after the expiration of the stay the judgment(s) or order(s) is not
discharged; (f) default in the observance or performance of any other covenant
or agreement in the Senior Debt Securities of such series or the Senior
Indenture for 90 days after notice by the Senior Trustee or holders of at least
25% in aggregate principal amount of the outstanding Senior Debt Securities of
the series (calculated in accordance with the formula set forth in such series
in the case of a series of Senior Debt Securities issued at an Original Issue
Discount); or (g) certain events of bankruptcy, insolvency or reorganization of
the Company or a Principal Constituent Bank (Section 4.01).

     In case an Event of Default with respect to the Senior Debt Securities of
any series shall occur and be continuing, the Senior Trustee or the holders of
not less than 25% in aggregate principal amount (in the case of a series of
Senior Debt Securities issued at an Original Issue Discount, calculated in
accordance with the formula set forth in such series) of all the outstanding
Senior Debt Securities of such series may declare the principal (or in the case
of a series

                                       15
<PAGE>
 
of Senior Debt Securities issued at an Original Issue Discount, the amount
calculated in accordance with the formula set forth in such series of Senior
Debt Securities) of all the securities of such series to be immediately due and
payable (Section 4.01). The Senior Indenture provides that the Senior Trustee,
within 90 days after the occurrence of a default with respect to Senior Debt
Securities of any series under the Senior Indenture, shall mail to the holders
of the Senior Debt Securities of such series notice of all uncured defaults
known to it that have not been waived (the term defaults to include events
specified above which, after notice or lapse of time or both, would become an
Event of Default); provided that, except in the case of default in the payment
of principal of or any premium or interest on any of the Senior Debt Securities
of that series or in the making of any sinking fund payment or analogous
obligation with respect to the Senior Debt Securities of such series, the Senior
Trustee may withhold such notice if it in good faith determines that withholding
such notice is in the interest of the holders of the securities of that series
(Section 4.08).

     Subject to the provisions of the Senior Indenture relating to the duties of
the Senior Trustee in case an Event of Default shall occur and be continuing,
the Senior Trustee is under no obligation to exercise any of the rights or
powers vested in it under the Senior Indenture at the request, order or
direction of any of the holders of the Senior Debt Securities, unless such
holders offer to the Senior Trustee reasonable security or indemnity (Section
5.02(d)). Subject to certain limitations contained in the Senior Indenture
(including among other limitations that the Senior Trustee will not be exposed
to personal liability), the holders of a majority in aggregate principal amount
of the outstanding Senior Debt Securities of all series affected (voting as one
class) have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Senior Trustee, or exercising any
trust or power conferred on the Senior Trustee (Section 4.07).

     No holder of any Senior Debt Security of any series will have any right to
institute any proceeding with respect to the Senior Indenture or for any remedy
thereunder, unless such holder previously shall have given to the Senior Trustee
written notice of a continuing Event of Default with respect to Senior Debt
Securities of that series and unless also the holders of not less than 25% in
aggregate principal amount (in the case of a series of Senior Debt Securities
issued at an Original Issue Discount, calculated in accordance with the formula
set forth in such series) of the outstanding Senior Debt Securities of that
series shall have made written request, and offered reasonable indemnity, to the
Senior Trustee to institute such proceeding as trustee, and the Senior Trustee
shall not have received from the holders of a majority in principal amount of
the outstanding Senior Debt Securities of that series a direction inconsistent
with such request and shall have failed to institute such proceeding within 60
days (Section 4.04). However, the holder of any Senior Debt Security will have
an absolute right to receive payment of the principal of and any premium and
interest, if any, on such Senior Debt Security on or after the due dates
expressed in such Senior Debt Security and to institute suit for the enforcement
of any such payment (Section 4.04).

     The Company is obligated to furnish annually to the Senior Trustee a
statement as to the performance by the Company of its obligations under the
Senior Indenture and as to any default in such obligations (Section 3.04).

DEFEASANCE

     The Company may terminate certain of its obligations under the Senior
Indenture with respect to the Senior Debt Securities of any series on the terms
and subject to the conditions contained in the Senior Indenture, by (a)
depositing irrevocably with the Senior Trustee as trust funds in trust (i) U.S.
dollars or U.S. Government Obligations (as defined below) in an amount which
through the payment of interest, principal and premium, if any, in respect
thereof in accordance with their terms will provide (without any reinvestment of
such interest, principal or premium), not later than one business day before the
due date of any payment, money or (ii) a combination of money and U.S.
Government Obligations sufficient to pay the principal of and any premium and
interest on the Senior Debt Securities of such series as such are due and (b)
satisfying certain other conditions precedent specified in the Senior Indenture.
Such deposit and termination are conditioned among other things upon the
Company's delivery of an opinion of independent counsel that the holders of the
Senior Debt Securities of such series will have no federal income tax
consequences as a result of such deposit and termination. Such termination will
not relieve the Company of its obligation to pay when due the principal of and
premium and interest on the Senior Debt Securities of such series if the Senior
Debt Securities of such series are not paid from the money or U.S. Government
Obligations held by the Senior Trustee for payment thereof (Section 13.05).

                                       16
<PAGE>
 
     "U.S. Government Obligations" means securities that are (i) direct
obligations of the United States of America for the payment of which its full
faith and credit are pledged or (ii) obligations of a Person controlled or
supervised by and acting as an agency or instrumentality of the United States of
America the payment of which is unconditionally guaranteed as a full faith and
credit obligation by the United States of America, which, in either case, under
clause (i) or (ii) are not callable or redeemable at the option of the issuer
thereof.

                         SUBORDINATED DEBT SECURITIES

     The Subordinated Debt Securities will be direct, unsecured obligations of
the Company and will rank equally and ratably with all outstanding subordinated
indebtedness of the Company. The Subordinated Debt Securities will have a
minimum weighted maturity of at least five years.

      SUBORDINATION

     The obligation of the Company to make any payment of principal, premium or
interest on the Subordinated Debt Securities, to the extent set forth in the
Subordinated Indenture, will be subordinate and junior in right of payment to
the prior payment in full of all existing and future Senior Indebtedness (as
defined). Upon any distribution of assets of the Company upon any dissolution,
winding up, liquidation or reorganization of the Company, the holders of Senior
Indebtedness are entitled to receive payment in full of principal and any
premium and interest before the holders of the Subordinated Debt Securities are
entitled to receive any payment on account of the principal of and any premium
or interest on the Subordinated Debt Securities, except holders of the
Subordinated Debt Securities, in a reorganization or readjustment of the
Company, may receive securities of the Company or any other corporation
subordinated to both Senior Indebtedness and any securities received in the
reorganization or readjustment by holders of Senior Indebtedness (except to the
extent that any securities so received are by their terms expressly not superior
in right of payment to the Subordinated Debt Securities) (Section 3.03). The
dissolution, winding up, liquidation or reorganization of the Company following
a conveyance, transfer or lease of its properties and assets substantially as an
entirety in compliance with the terms described above under "Consolidation,
Merger, Sale, Conveyance and Lease" will not be deemed to be a dissolution,
winding up, liquidation or reorganization for this purpose (Section 3.03(d)). In
addition, the Company may not pay principal of, or any premium or interest on,
the Subordinated Debt Securities and may not acquire any Subordinated Debt
Securities for cash or property other than capital stock of the Company if: (1)
a default on Senior Indebtedness occurs and is continuing that permits holders
of such Senior Indebtedness to accelerate its maturity; and (2) such default is
the subject of judicial proceedings or the Company receives written notice of
such default from a representative of all holders of such Senior Indebtedness.
If the Company receives any such notice, a similar notice received within 360
days thereafter relating to the same default on the same issue of Senior
Indebtedness shall not be effective for such purpose. The Company may resume
payments on the Subordinated Debt Securities and may acquire them when: (i) such
default is cured or waived or shall have ceased to exist, or the Senior
Indebtedness to which such default relates shall have been paid in full in cash
or cash equivalent; or (ii) if such default is not the subject of judicial
proceedings, 120 days pass after such written notice is received by the Company
(Section 3.02(b)).

     By reason of this subordination, in the event of the Company's insolvency,
holders of Senior Indebtedness may receive more, ratably, and holders of the
Subordinated Debt Securities may receive less, ratably, than other creditors of
the Company. However, such subordination will not prevent the occurrence of any
Event of Default (Section 3.12).

     The Subordinated Indenture does not restrict the incurrence of additional
Senior Indebtedness.

     "Senior Indebtedness" means the principal of, and premium, if any, on (a)
all obligations of the Company for money borrowed, whether outstanding on the
date of execution of the Subordinated Indenture or thereafter created, except
(i) such indebtedness as is by its terms expressly stated to be junior in right
of payment to the Subordinated Debt Securities and (ii) such indebtedness as is
by its terms expressly stated to rank pari passu in right of payment with the
Subordinated Debt Securities, and (b) any deferrals, renewals or extensions of
any such Senior Indebtedness.

LIMITED RIGHTS OF ACCELERATION

     Unless otherwise specified in the Prospectus Supplement relating to any
series of Subordinated Debt Securities, payment of principal of the Subordinated
Debt Securities may be accelerated only in the case of an "Acceleration Event"
which is defined in the Indenture as any of the bankruptcy, insolvency or
reorganization events with respect to the Company that constitute an Event of
Default (as defined below). There is no right of acceleration in the case of a
default in the payment of principal of or any premium or interest on the
Subordinated Debt Securities or the performance of any other covenant of the
Company in the Subordinated Indenture.

EVENTS OF DEFAULT

     The Subordinated Indenture defines an Event of Default with respect to any
particular series of Subordinated Debt Securities as being any one of the
following events unless it is either inapplicable to a particular series or
specifically deleted or modified for the Subordinated Debt Securities of such
series: (a) default for 30 days in the payment of any interest on any of the
Subordinated Debt Securities of that series; (b) default in the payment of the
principal of or any premium on any of the Subordinated Debt Securities of that
series when due; (c) default in the payment of any sinking fund installment or
analogous obligation with respect to that series when due; (d) a default or
event of default under any instrument under which there may be issued or
borrowed, or by which there may be secured or evidenced, any indebtedness of the
Company (other than the Subordinated Debt Securities of such series or
indebtedness to a Subsidiary) or of any Subsidiary (other than indebtedness of
any Subsidiary owing to the Company or to another Subsidiary) shall happen and
not less than $1,000,000 of such indebtedness shall be past due, or become due
by acceleration, and such indebtedness or acceleration is not discharged or
rescinded within 15 days after notice by the Subordinated Trustee or holders of
at least 25% in aggregate principal amount (in the case of a series of
Subordinated Debt Securities issued at an Original Issue Discount, calculated in
accordance with the formula set forth in such series) of the outstanding
Subordinated Debt Securities of that series; (e) final judgment(s) or order(s)
for the payment of money in excess of $1,000,000 is entered against the Company
or one or more Principal Constituent Banks and within 90 days of entry is not
discharged, or the execution thereof is not stayed pending appeal, or within 90
days after the expiration of the stay, the judgment(s) or order(s) is not
discharged; (f) default in the observance or performance of any other covenant
or agreement in the Subordinated Debt Securities of such series or the
Subordinated Indenture for 90 days after notice by the Subordinated Trustee or
holders of at least 25% in aggregate principal amount (in the case of a series
of Subordinated Debt Securities issued at an Original Issue Discount, calculated
in accordance with the formula set forth in such series) of the outstanding
Subordinated Debt Securities of the series; or (g) certain events of bankruptcy,
insolvency or reorganization of the Company or a Principal Constituent Bank
(Section 5.01). Rights of acceleration in case an Event of Default occurs are
limited. See "Limited Rights of Acceleration."

     In case an Acceleration Event shall have occurred and be continuing, the
Subordinated Trustee or the holders of not less than 25% in aggregate principal
amount (in the case of a series of Subordinated Debt Securities issued at an
Original Issue Discount, calculated in accordance with the formula set forth in
such series) of the outstanding Subordinated Debt Securities of such series may
declare the principal (or, in the case of a series of Subordinated Debt
Securities issued at an Original Issue Discount, the amount calculated in
accordance with the formulas set forth in such series of Subordinated Debt
Securities) of all the securities of such series to be immediately due and
payable (Section 5.01). The Subordinated Indenture provides that the
Subordinated Trustee, within 90 days after the occurrence of a default with
respect to Subordinated Debt Securities of any series under the Subordinated
Indenture, shall mail to the holders of the Subordinated Debt Securities of such
series notice of all uncured defaults known to it that have not been waived (the
term defaults to include events specified above which, after notice or lapse of
time or both, would become an Event of Default); provided that, except in the
case of default in the payment of principal of or any premium or interest on any
of the Subordinated Debt Securities of that series or in the making of any
sinking fund payment or analogous obligation with respect to the Subordinated
Debt Securities of such series, the Subordinated Trustee may withhold such
notice if it in good faith determines that withholding such notice is in the
interest of the holders of the Subordinated Debt Securities of that series
(Section 5.08).

                                       18
<PAGE>
 
     Subject to the provisions of the Subordinated Indenture relating to the
duties of the Subordinated Trustee in case an Event of Default shall occur and
be continuing, the Subordinated Trustee is under no obligation to exercise any
of the rights or powers vested in it under the Subordinated Indenture at the
request, order or direction of any of the holders of the Subordinated Debt
Securities, unless such holder offers to the Subordinated Trustee reasonable
security or indemnity (Section 6.02(d)). Subject to certain limitations
contained in the Subordinated Indenture (including among other limitations that
the Subordinated Trustee will not be exposed to personal liability), the holders
of a majority in aggregate principal amount of the outstanding Subordinated Debt
Securities of all series affected (voting as one class) have the right to direct
the time, method and place of conducting any proceeding for any remedy available
to the Subordinated Trustee, or exercising any trust or power conferred on the
Subordinated Trustee (Section 5.07).

     No holder of any Subordinated Debt Security of any series will have any
right to institute any proceeding with respect to the Subordinated Indenture or
for any remedy thereunder unless such holder previously shall have given to the
Subordinated Trustee written notice of a continuing Event of Default with
respect to Subordinated Debt Securities of that series and unless also the
holders of not less than 25% in aggregate principal amount (in the case of a
series of Subordinated Debt Securities issued at an Original Issue Discount,
calculated in accordance with the formula set forth in such series) of the
outstanding Subordinated Debt Securities of that series shall have made written
request, and offered reasonable indemnity, to the Subordinated Trustee to
institute such proceeding as trustee, and the Subordinated Trustee shall not
have received from the holders of a majority in principal amount of the
outstanding Subordinated Debt Securities of that series a direction inconsistent
with such request and shall have failed to institute such proceeding within 60
days (Section 5.04). However, the holder of any Subordinated Debt Security will
have an absolute right to receive payment of the principal of and any premium
and interest on such Subordinated Debt Security on or after the due dates
expressed in such Subordinated Debt Security and to institute suit for the
enforcement of any such payment (Section 5.04).

     The Company is obligated to furnish to the Subordinated Trustee annually a
statement as to the performance by the Company of its obligations under the
Subordinated Indenture and as to any default in such obligations (Section 4.04).

                        VALIDITY OF OFFERED SECURITIES

     The validity of any Offered Securities will be passed upon for the Company
by Womble Carlyle Sandridge & Rice, PLLC, Charlotte, North Carolina, and for any
underwriters or agents by Gibson, Dunn & Crutcher, New York, New York. Gibson,
Dunn & Crutcher will rely upon the opinion of Womble Carlyle Sandridge & Rice,
PLLC as to matters of North Carolina law, and Womble Carlyle Sandridge & Rice,
PLLC will rely upon the opinion of Gibson, Dunn & Crutcher as to matters of New
York law.

                                    EXPERTS

     The consolidated financial statements and schedule included in the
Company's 1995 Annual Report on Form 10-K incorporated by reference in this
Prospectus have been audited by Arthur Andersen LLP, independent public
accountants, as indicated in their reports with respect thereto, and are
incorporated by reference herein upon the authority of said firm as experts in
giving said reports.

                             PLAN OF DISTRIBUTION

     The Company may offer and sell Debt Securities to or through underwriters
to be designated from time to time, and also may offer and sell Debt Securities
directly to other purchasers or through agents. The distribution of the Debt
Securities may be effected from time to time in one or more transactions at a
fixed price or prices, which may be changed, or at market prices prevailing at
the time of sale, at prices related to such prevailing market prices or at
negotiated prices.

     The Debt Securities will be new issues of securities with no established
trading market. It has not presently been established whether the underwriters,
if any, of the Debt Securities will make a market in the Debt Securities. If a
market

                                       19
<PAGE>
 
in the Debt Securities is made by any such underwriters, such market making may
be discontinued at any time without notice. No assurance can be given as to the
liquidity of the trading market for the Debt Securities.

     In connection with the sale of Debt Securities, underwriters may receive
compensation from the Company or from purchasers of Debt Securities for whom
they may act as agents in the form of discounts, concessions or commissions.
Underwriters may sell Debt Securities to or through dealers, and such dealers
may receive compensation in the form of discounts, concessions or commissions
from the underwriters and/or commissions from the purchasers for whom they may
act as agents. Underwriters, dealers and agents that participate in the
distribution of Debt Securities may be deemed to be underwriters, and any
discounts or commissions received by them from the Company and any profit on the
resale of Debt Securities by them may be deemed to be underwriting discounts and
commissions under the Securities Act. Any such underwriter or agent will be
identified, and any such compensation received from the Company will be
described, in the applicable Prospectus Supplement(s) relating to such Debt
Securities.

     Unless otherwise indicated in the applicable Prospectus Supplement(s), the
obligations of any such underwriters to purchase the Debt Securities will be
subject to certain conditions precedent, and each of the underwriters with
respect to a sale of Debt Securities will be obligated to purchase all of its
Debt Securities if any are purchased. Unless otherwise indicated in the
applicable Prospectus Supplement(s), any such agent involved in the offer and
sale of the Debt Securities in respect of which this Prospectus is being

     If so indicated in the applicable Prospectus Supplement(s) relating to any
Offered Securities, the Company will authorize dealers or other persons acting
as the Company's agents to solicit offers by certain institutions to purchase
any Offered Securities from the Company pursuant to contracts providing for
payment and delivery on a future date. Institutions with which such contracts
may be made include commercial and savings banks, insurance companies, pension
funds, investment companies, educational and charitable institutions and others,
but in all cases such institutions must be approved by the Company. The
obligations of any purchaser under any such contract will be subject to the
condition that the purchase of any Offered Securities shall not at the time of
delivery be prohibited under the laws of the jurisdiction to which such
purchaser is subject. The underwriters and such other agents will not have any
responsibility in respect of the validity or performance of such contracts.

     Underwriters or agents and their associates may be customers of (including
borrowers from), engage in transactions with, and/or perform services for, the
Company and its subsidiaries, the Senior Trustee and the Subordinated Trustee,
in the ordinary course of business.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Sections 55-8-50 through 55-8-58 of the North Carolina Business Corporation
Act contain specific provisions relating to indemnification of directors and
officers of North Carolina corporations. In general, such sections provide that
(i) a corporation must indemnify a director or officer who is wholly successful
in his defense of a proceeding to which he is a party because of his status as
such, unless limited by the articles of incorporation, and (ii) a corporation
may indemnify a director or officer if he is not wholly successful in such
defense, if it is determined as provided by statute that the director or officer
meets a certain standard of conduct, provided when a director or officer is
liable to the corporation or is adjudged liable on the basis that personal
benefit was improperly received by him, the corporation may not indemnify him. A
director or officer of a corporation who is a party to a proceeding may also
apply to the courts for indemnification, and the court may order indemnification
under certain circumstances set forth in the statute. A corporation may, in its
articles of incorporation or bylaws or by contract or resolution, provide
indemnification in addition to that provided by statute, subject to certain
conditions.

     The Company's bylaws provide for the indemnification of any director or
officer of the Company against liabilities and litigation expenses arising out
of his status as such, excluding (i) any liabilities or litigation expenses
relating to activities which were at the time taken known or believed by such
person to be clearly in conflict with the best interest of the Company and
(ii) that portion of any liabilities or litigation expenses with respect to
which such person is entitled to receive payment under any insurance policy.

     The Company's articles of incorporation provide for the elimination of the
personal liability of each director of the Company to the fullest extent
permitted by law.

     The Company maintains directors and officers liability insurance which, in
general, insures (i) the Company's directors and officers against loss by reason
of any of their wrongful acts and/or (ii) the Company against loss arising from
claims against the directors and officers by reason of their wrongful acts, all
subject to the terms and conditions contained in the policy.

     Effective April 1, 1996, certain rules of the Federal Deposit Insurance
Corporation will limit the ability of certain depository institutions, their
subsidiaries and their affiliated depository institution holding companies to
indemnify affiliated parties, including institution directors. In general,
subject to the ability to purchase directors and officers liability insurance
and to advance professional expenses under certain circumstances, the rules will
prohibit such institutions from indemnifying a director for certain costs
incurred with regard to an administrative or enforcement action commenced by any
federal banking agency which results in a final order or settlement pursuant to
which the director is assessed a civil money penalty, removed from office,
prohibited from participating in the affairs of an insured

ITEM 17. UNDERTAKINGS.

     (1)       The undersigned registrant hereby undertakes:

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

                                      II-2
<PAGE>
 
                    (i) To include any prospectus required by Section 
               10(a)(3) of the Securities Act of 1933 (as amended, the 
               "Securities Act");

                    (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 end of the estimated maximum
               offering range may be reflected in the form of prospectus filed
               with the Commission pursuant to Rule 424(b) if, in the aggregate,
               the changes in volume and price represent no more than 20 percent
               change in the maximum aggregate offering price set forth in the
               "Calculation of Registration Fee" table in the effective
               registration statement; and

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

          provided, however, that paragraphs (1)(A)(i) and (1)(A)(ii) do not
          apply if the information required to be included in a post-effective
          amendment by those paragraphs is contained in periodic reports filed
          with or furnished to the Commission by the registrant pursuant to
          Section 13 or Section 15(d) of the Securities Exchange Act of 1934 (as
          amended, the "Exchange Act") that are incorporated by reference in the
          registration statement.

               (B)  That, for the purpose of determining any liability under the
          Securities Act, 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.

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

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

     (3)  The undersigned registrant hereby undertakes that:

               (A)  For purposes of determining any liability under the
          Securities Act, 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.

               (B)  For the purpose of determining any liability under the
          Securities Act, 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.

                                      II-3
<PAGE>
 
     (4)  The undersigned registrant hereby undertakes to file an application
for the purpose of determining the eligibility of the trustee to act under
subsection (a) of section 310 of the Trust Indenture Act ("Act") in accordance
with the rules and regulations prescribed by the Commission under section
305(b)(2) of the Act.

     (5)  Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities 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 Securities
Act and will be governed by the final adjudication of such issue.

     Pursuant to the requirements of the Securities Act of 1933, as amended, the
registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-3 and has duly caused this Registration
Statement on Form S-3 to be signed on its behalf by the undersigned, thereunto
duly authorized, in the City of Winston-Salem, State of North Carolina, on
April 26, 1996.

                                Debt Securities

                            UNDERWRITING AGREEMENT
                            ----------------------

                                                               ___________, 1996
MERRILL LYNCH & CO.
Merrill Lynch, Pierce, Fenner & Smith
          Incorporated
North Tower
World Financial Center
New York, New York 10281-1209

Ladies and Gentlemen:

          Southern National Corporation, a North Carolina corporation (the
"Company"), proposes to issue and sell up to $1,000,000,000 aggregate principal
amount of its senior or subordinated debt securities (the "Debt Securities"),
from time to time, in or pursuant to one or more offerings on terms to be
determined at the time of sale.

          The Debt Securities will be issued in one or more series as senior
indebtedness (the "Senior Debt Securities") under an indenture, dated as of
_____________, 1996 (the "Senior Indenture"), between the Company and
___________, as trustee (the "Senior Trustee"), or as subordinated indebtedness
(the "Subordinated Debt Securities") under an indenture, dated as of __________,
1996 (the "Subordinated Indenture", and collectively with the Senior Indenture,
the "Indentures", and each, an "Indenture"), between the Company and
_____________, as trustee (the "Subordinated Trustee", and collectively with the
Senior Trustee, the "Trustees", and each, a "Trustee"). Each series of Debt
Securities may vary, as applicable, as to title, aggregate principal amount,
rank, interest rate or formula and timing of payments thereof, stated maturity
date, redemption and/or repayment provisions, sinking fund requirements and any
other variable terms established by or pursuant to the applicable Indenture.

          Whenever the Company determines to make an offering of Debt Securities
through Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated
("Merrill Lynch"), or through an underwriting syndicate managed by Merrill
Lynch, the Company will enter into an agreement (each, a "Terms Agreement")
providing for the sale of such Debt Securities to, and the purchase and offering
thereof by, Merrill Lynch and such other underwriters, if any, selected by
Merrill Lynch (the "Underwriters", which term shall include

                                       1
<PAGE>
 
Merrill Lynch, whether acting as sole Underwriter or as a member of an
underwriting syndicate, as well as any Underwriter substituted pursuant to
Section 10 hereof). The Terms Agreement relating to the offering of Debt
Securities shall specify the aggregate principal amount of Debt Securities to be
initially issued, the name of each Underwriter participating in such offering
(subject to substitution as provided in Section 10 hereof) and the name of any
Underwriter other than Merrill Lynch acting as co-manager in connection with
such offering, the aggregate principal amount of Debt Securities which each such
Underwriter severally agrees to purchase, whether such offering is on a fixed or
variable price basis and, if on a fixed price basis, the initial offering price,
the price at which the Debt Securities are to be purchased by the Underwriters,
the form, time, date and place of delivery and payment of the Debt Securities
and any other material variable terms of the Debt Securities. The Terms
Agreement, which shall be substantially in the form of Exhibit A hereto, may
take the form of an exchange of any standard form of written telecommunication
between the Company and Merrill Lynch, acting for itself and, if applicable, as
representative of any other Underwriters. Each offering of Debt Securities
through Merrill Lynch as sole Underwriter or through an underwriting syndicate
managed by Merrill Lynch will be governed by this Underwriting Agreement, as
supplemented by the applicable Terms Agreement.

          The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3 (No. 333-_______) [and pre-
effective amendment[s] no[s]. __ thereto] for the registration of the Debt
Securities under the Securities Act of 1933, as amended (the "1933 Act"), and
the offering thereof from time to time in accordance with Rule 415 of the rules
and regulations of the Commission under the 1933 Act (the "1933 Act
Regulations"), and the Company has filed such post-effective amendments thereto
as may be required prior to the execution of the applicable Terms Agreement.
Such registration statement (as so amended, if applicable) has been declared
effective by the Commission and each Indenture has been duly qualified under the
Trust Indenture Act of 1939, as amended (the "1939 Act"). Such registration
statement (as so amended, if applicable), including the information, if any,
deemed to be a part thereof pursuant to Rule 430A(b) of the 1933 Act Regulations
(the "Rule 430A Information") or Rule 434(d) of the 1933 Act Regulations (the
"Rule 434 Information"), is referred to herein as the "Registration Statement";
and the final prospectus and the prospectus supplement relating to the offering
of the Debt Securities, in the form first furnished to the Underwriters by the
Company for use in connection with the offering of the Debt Securities, are
collectively referred to herein as the "Prospectus"; provided, however, that all
references to the "Registration Statement" and the "Prospectus" shall be deemed
to include all documents incorporated therein by reference pursuant to the
Securities Exchange Act of 1934, as amended (the "1934 Act"), prior to the
execution of the applicable Terms Agreement; provided, further, that if the
Company files a registration statement with the Commission pursuant to Section
462(b) of the 1933 Act Regulations (the "Rule 462 Registration Statement"),
then, after such filing, all references to "Registration Statement" shall be
deemed to include the Rule 462 Registration Statement; and provided, further,
that if the Company elects to rely upon Rule 434 of the 1933 Act Regulations,
then all references to "Prospectus" shall be deemed to include the final or
preliminary prospectus and the applicable term sheet or

                                       2
<PAGE>
 
abbreviated term sheet (the "Term Sheet"), as the case may be, in the form first
furnished to the Underwriters by the Company in reliance upon Rule 434 of the
1933 Act Regulations, and all references in this Underwriting Agreement to the
date of the Prospectus shall mean the date of the Term Sheet. A "preliminary
prospectus" shall be deemed to refer to any prospectus used before the
registration statement became effective and any prospectus that omitted, as
applicable, the Rule 430A Information, the Rule 434 Information or other
information to be included upon pricing in a form of prospectus filed with the
Commission pursuant to Rule 424(b) of the 1933 Act Regulations, that was used
after such effectiveness and prior to the execution and delivery of the
applicable Terms Agreement. For purposes of this Underwriting Agreement, all
references to the Registration Statement, Prospectus, Term Sheet or preliminary
prospectus or to any amendment or supplement to any of the foregoing shall be
deemed to include the copy filed with the Commission pursuant to its Electronic
Data Gathering, Analysis and Retrieval system ("EDGAR").

          All references in this Underwriting Agreement to financial statements
and schedules and other information which is "contained," "included" or "stated"
(or other references of like import) in the Registration Statement, Prospectus
or preliminary prospectus shall be deemed to mean and include all such financial
statements and schedules and other information which is incorporated by
reference in the Registration Statement, Prospectus or preliminary prospectus,
as the case may be; and all references in this Underwriting Agreement to
amendments or supplements to the Registration Statement, Prospectus or
preliminary prospectus shall be deemed to mean and include the filing of any
document under the 1934 Act which is incorporated by reference in the
Registration Statement, Prospectus or preliminary prospectus, as the case may
be.

          SECTION 1.  Representations and Warranties
                      ------------------------------

          (a) The Company represents and warrants to Merrill Lynch, as of the
date hereof, and to each Underwriter named in the applicable Terms Agreement, as
of the date thereof, and as of the Closing Time (as defined below) (in each
case, a "Representation Date"), as follows:

               (1)    Compliance with Registration Requirements. The Company
                      -----------------------------------------
     meets the requirements for use of Form S-3 under the 1933 Act. Each of the
     Registration Statement and any Rule 462(b) Registration Statement has
     become effective under the 1933 Act and no stop order suspending the
     effectiveness of the Registration Statement or any Rule 462(b) Registration
     Statement has been issued under the 1933 Act and no proceedings for that
     purpose have been instituted or are pending or, to the knowledge of the
     Company, are contemplated by the Commission, and any request on the part of
     the Commission for additional information has been complied with. In
     addition, each Indenture has been duly qualified under the 1939 Act.

               At the respective times the Registration Statement, any Rule
     462(b) Registration Statement and any post-effective amendments thereto
     (including the filing

                                       3
<PAGE>
 
     of the Company's most recent Annual Report on Form 10-K with the Commission
     (the "Annual Report on Form 10-K")) became effective and at each
     Representation Date, the Registration Statement, any Rule 462(b)
     Registration Statement and any amendments and supplements thereto complied
     and will comply in all material respects with the requirements of the 1933
     Act and the 1933 Act Regulations and the 1939 Act and the rules and
     regulations of the Commission under the 1939 Act (the "1939 Act
     Regulations") and did not and will not contain an untrue statement of a
     material fact or omit to state a material fact required to be stated
     therein or necessary to make the statements therein not misleading. At the
     date of the Prospectus and at the Closing Time, the Prospectus and any
     amendments and supplements thereto did not and will not include an untrue
     statement of a material fact or omit 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. If the Company elects to rely
     upon Rule 434 of the 1933 Act Regulations, the Company will comply with the
     requirements of Rule 434. Notwithstanding the foregoing, the
     representations and warranties in this subsection shall not apply to
     statements in or omissions from the Registration Statement or the
     Prospectus made in reliance upon and in conformity with information
     furnished to the Company in writing by any Underwriter through Merrill
     Lynch expressly for use in the Registration Statement or the Prospectus.

               Each preliminary prospectus and prospectus filed as part of the
     Registration Statement as originally filed or as part of any amendment
     thereto, or filed pursuant to Rule 424 under the 1933 Act, complied when so
     filed in all material respects with the 1933 Act Regulations and, if
     applicable, each preliminary prospectus and the Prospectus delivered to the
     Underwriters for use in connection with the offering of Debt Securities
     will, at the time of such delivery, be identical to the electronically
     transmitted copies thereof filed with the Commission pursuant to EDGAR,
     except to the extent permitted by Regulation S-T.

               (2)    Incorporated Documents.  The documents incorporated or
                      ----------------------
     deemed to be incorporated by reference in the Registration Statement and
     the Prospectus, at the time they were or hereafter are filed with the
     Commission, complied and will comply in all material respects with the
     requirements of the 1934 Act and the rules and regulations of the
     Commission thereunder (the "1934 Act Regulations") and, when read together
     with the other information in the Prospectus, at the date of the Prospectus
     and at the Closing Time, did not and will not include an untrue statement
     of a material fact or omit to state a material fact necessary to make the
     statements therein, in the light of the circumstances under which they were
     made, not misleading.

     thereunder will have been, duly authorized, executed and delivered by the
     Company and, upon such authorization, execution and delivery, will
     constitute a valid and legally binding agreement of the Company,
     enforceable against the Company in accordance with its terms, except as the
     enforcement thereof may be limited by bankruptcy, insolvency,
     reorganization, moratorium or other similar laws relating to or affecting
     creditors' rights generally or by general equitable principles.

     the Prospectus and will be in substantially the form filed or incorporated
     by reference, as the case may be, as an exhibit to the Registration
     Statement.

     (as defined below) under, or result in the creation or imposition of any
     lien, charge or encumbrance upon any assets, properties or operations of
     the Company or any subsidiary pursuant to, any Agreements and Instruments,
     except for such conflicts, breaches, defaults, events or liens, charges or
     encumbrances that would not result in a Material Adverse Effect, nor will
     such action result in any violation of the provisions of the charter or by-
     laws of the Company or any subsidiary or any applicable law, statute, rule,
     regulation, judgment, order, writ or decree of any government, government
     instrumentality or court, domestic or foreign, having jurisdiction over the
     Company or any subsidiary or any of their assets, properties or operations.
     As used herein, a "Repayment Event" means any event or condition which
     gives the holder of any note, debenture or other evidence of indebtedness
     (or any person acting on such holder's behalf) the right to require the
     repurchase, redemption or repayment of all or a portion of such
     indebtedness by the Company or any subsidiary.

          (b)  Officers' Certificates.  Any certificate signed by any officer of
the Company or any subsidiary and delivered to any Underwriter or to counsel for
the Underwriters in connection with the offering of the Debt Securities shall be
deemed a representation and warranty by the Company to each Underwriter as to
the matters covered thereby on the date of such certificate and, unless
subsequently amended or supplemented, at each Representation Date subsequent
thereto. 

          SECTION 2.  Sale and Delivery to Underwriters; Closing.
                      ------------------------------------------

          (a)  Debt Securities. The several commitments of the Underwriters to
purchase the Debt Securities pursuant to the applicable Terms Agreement shall be
deemed to have been made on the basis of the representations and warranties
herein contained and shall be subject to the terms and conditions herein set
forth.

          (b)  Payment. Payment of the purchase price for, and delivery of, the
Debt Securities shall be made at the office of Gibson, Dunn & Crutcher, 200 Park
Avenue, New York, New York 10166, or at such other place as shall be agreed upon
by Merrill Lynch and the Company, at 10:00 A.M. (Eastern time) on the third
(fourth, if the pricing occurs after 4:30 P.M. (Eastern time) on any given day)
business day after the date hereof (unless postponed in accordance with the
provisions of Section 10 hereof), or such other time not later than ten business
days after such date as shall be agreed upon by Merrill Lynch and the Company
(such time and date of payment and delivery being herein called "Closing
Time").

          Payment shall be made to the Company by certified or official bank
check or checks drawn in New York Clearing House funds or similar next day funds
payable to the order of the Company, against delivery to Merrill Lynch for the
respective accounts of the Underwriters of the Debt Securities to be purchased
by them. It is understood that each Underwriter has authorized Merrill Lynch,
for its account, to accept delivery of, receipt for, and make payment of the
purchase price for, the Debt Securities which it has severally agreed to
purchase. Merrill Lynch, individually and not as representative of the
Underwriters, may (but shall not be obligated to) make payment of the purchase
price for the Debt Securities to

                                       7
<PAGE>
 
be purchased by any Underwriter whose check has not been received by the Closing
Time, but such payment shall not relieve such Underwriter from its obligations
hereunder.

          (c)  Denominations; Registration.  The Debt Securities shall be in
such denominations and registered in such names as Merrill Lynch may request in
writing at least one full business day prior to the Closing Time. The Debt
Securities will be made available for examination and packaging by Merrill
Lynch in The City of New York not later than 10:00 A.M. (Eastern time) on the
business day prior to the Closing Time.

          SECTION 3.  Covenants of the Company. The Company covenants with
                      ------------------------
Merrill Lynch and with each Underwriter participating in the offering of Debt
Securities, as follows:

               (a)    Compliance with Securities Regulations and Commission
     Requests.  The Company, subject to Section 3(b), will comply with the
     requirements of Rule 430A of the 1933 Act Regulations and/or Rule 434 of
     the 1933 Act Regulations, if and as applicable, and will notify the
     Representative(s) immediately of (i) the effectiveness of any post-
     effective amendment to the Registration Statement or the filing of any
     supplement or amendment to the Prospectus, (ii) the receipt of any comments
     from the Commission, (iii) any request by the Commission for any amendment
     to the Registration Statement or any amendment or supplement to the
     Prospectus or for additional information, and (iv) the issuance by the
     Commission of any stop order suspending the effectiveness of the
     Registration Statement or of any order preventing or suspending the use of
     any preliminary prospectus, or of the suspension of the qualification of
     the Debt Securities for offering or sale in any jurisdiction, or of the
     initiation or threatening of any proceedings for any of such purposes. The
     Company will promptly effect the filings necessary pursuant to Rule 424 and
     will take such steps as it deems necessary to ascertain promptly whether
     the Prospectus transmitted for filing under Rule 424 was received for
     filing by the Commission and, in the event that it was not, it will
     promptly file the Prospectus. The Company will make every reasonable effort
     to prevent the issuance of any stop order and, if any stop order is issued,
     to obtain the lifting thereof at the earliest possible moment.

               (b)    Filing of Amendments.  The Company will give Merrill Lynch
     notice of its intention to file or prepare any amendment to the
     Registration Statement (including any filing under Rule 462(b) of the 1933
     Act Regulations), any Term Sheet or any amendment, supplement or revision
     to either the prospectus included in the Registration Statement at the time
     it became effective or to the Prospectus, whether pursuant to the 1933 Act,
     the 1934 Act or otherwise, will furnish Merrill Lynch with copies of any
     such documents a reasonable amount of time prior to such proposed filing or
     use, as the case may be, and will not file or use any such document to
     which Merrill Lynch or counsel for the Underwriters shall object.

                                       8
<PAGE>
 
               (c)    Delivery of Registration Statements. The Company has
     furnished or will deliver to Merrill Lynch and counsel for the
     Underwriters, without charge, signed copies of the Registration Statement
     as originally filed and of each amendment thereto (including exhibits filed
     therewith or incorporated by reference therein and documents incorporated
     or deemed to be incorporated by reference therein) and signed copies of all
     consents and certificates of experts, and will also deliver to Merrill
     Lynch, without charge, a conformed copy of the Registration Statement as
     originally filed and of each amendment thereto (without exhibits) for each
     of the Underwriters. If applicable, the copies of the Registration
     Statement and each amendment thereto furnished to the Underwriters will be
     identical to the electronically transmitted copies thereof filed with the
     Commission pursuant to EDGAR, except to the extent permitted by Regulation
     S-T.

               (d)    Delivery of Prospectuses. The Company will deliver to each
     Underwriter, without charge, as many copies of each preliminary prospectus
     as such Underwriter may reasonably request, and the Company hereby consents
     to the use of such copies for purposes permitted by the 1933 Act. The
     Company will furnish to each Underwriter, without charge, during the period
     when the Prospectus is required to be delivered under the 1933 Act or the
     1934 Act, such number of copies of the Prospectus as such Underwriter may
     reasonably request. If applicable, the Prospectus and any amendments or
     supplements thereto furnished to the Underwriters will be identical to the
     electronically transmitted copies thereof filed with the Commission
     pursuant to EDGAR, except to the extent permitted by Regulation S-T.

               (e)    Continued Compliance with Securities Laws. The Company
     will comply with the 1933 Act, the 1933 Act Regulations, the 1934 Act and
     the 1934 Act Regulations so as to permit the completion of the distribution
     of the Debt Securities as contemplated in this Underwriting Agreement and
     the applicable Terms Agreement and in the Registration Statement and the
     Prospectus. If at any time when the Prospectus is required by the 1933 Act
     or the 1934 Act to be delivered in connection with sales of the Securities,
     any event shall occur or condition shall exist as a result of which it is
     necessary, in the opinion of counsel for the Underwriters or for the
     Company, to amend the Registration Statement in order that the Registration
     Statement will not contain an untrue statement of a material fact or omit
     to state a material fact required to be stated therein or necessary to make
     the statements therein not misleading or to amend or supplement the
     Prospectus in order that the Prospectus will not include an untrue
     statement of a material fact or omit to state a material fact necessary in
     order to make the statements therein not misleading in the light of the
     circumstances existing at the time it is delivered to a purchaser, or if it
     shall be necessary, in the opinion of such counsel, at any such time to
     amend the Registration Statement or amend or supplement the Prospectus in
     order to comply with the requirements of the 1933 Act or the 1933 Act
     Regulations, the Company will promptly prepare and file with the
     Commission, subject to Section 3(b), such amendment or supplement as may be
     necessary to correct such statement or omission

                                       9
<PAGE>
 
     or to make the Registration Statement or the Prospectus comply with such
     requirements, and the Company will furnish to the Underwriters, without
     charge, such number of copies of such amendment or supplement as the
     Underwriters may reasonably request.

               (f)    Blue Sky Qualifications. The Company will use its best
     efforts, in cooperation with the Underwriters, to qualify the Debt
     Securities for offering and sale under the applicable securities laws of
     such states and the jurisdictions (domestic or foreign) as Merrill Lynch
     may designate and to maintain such qualifications in effect for a period of
     not less than one year from the date of the applicable Terms Agreement;
     provided, however, that the Company shall not be obligated to file any
     general consent to service of process or to qualify as a foreign
     corporation or as a dealer in securities in any jurisdiction in which it is
     not so qualified or to subject itself to taxation in respect of doing
     business in any jurisdiction in which it is not otherwise so subject. In
     each jurisdiction in which the Debt Securities have been so qualified, the
     Company will file such statements and reports as may be required by the
     laws of such jurisdiction to continue such qualification in effect for a
     period of not less than one year from the date of such Terms Agreement.

               (g)    Earnings Statement. The Company will timely file such
     reports pursuant to the 1934 Act as are necessary in order to make
     generally available to its security holders as soon as practicable an
     earnings statement for the purposes of, and to provide the benefits
     contemplated by, the last paragraph of Section 11(a) of the 1933 Act.

               (h)    Use of Proceeds. The Company will use the net proceeds
     received by it from the sale of the Debt Securities in the manner specified
     in the Prospectus under "Use of Proceeds."

               (i)    Listing. The Company will use its best efforts to effect
     the listing of the Debt Securities prior to the Closing Time, on any
     national securities exchange or quotation system if and as specified in the
     applicable Terms Agreement.

               (j)    Restriction on Sale of Securities. Between the date of the
     applicable Terms Agreement and the Closing Time or such other date
     specified in such Terms Agreement, the Company will not, without the prior
     written consent of Merrill Lynch, directly or indirectly, issue, sell,
     offer to sell, grant any option for the sale of, or otherwise dispose of,
     the securities specified in such Terms Agreement.

               (k)    Reporting Requirements. The Company, during the period
     when the Prospectus is required to be delivered under the 1933 Act or the
     1934 Act, will file all documents required to be filed with the Commission
     pursuant to the 1934 Act within the time periods required by the 1934 Act
     and the 1934 Act Regulations.

acting in the capacity of a "qualified independent underwriter" (as defined in
Section 2(l) of Schedule E of the bylaws of the NASD), if applicable.

          (b)  Termination of Agreement. If the applicable Terms Agreement is
terminated by Merrill Lynch in accordance with the provisions of Section 5 or
Section 9(b)(i) hereof, the Company shall reimburse the Underwriters for all of
their out-of-pocket expenses, including the reasonable fees and disbursements of
counsel for the Underwriters in connection with the offer and sale of the Debt
Securities contemplated by this Agreement.

          SECTION 5.  Conditions of Underwriters' Obligations. The obligations
                      --------------------------------------- 
of the Underwriters to purchase and pay for the Debt Securities pursuant to the
applicable Terms Agreement are subject to the accuracy of the representations
and warranties of the Company contained in Section 1 hereof or in certificates
of any officer of the Company or any subsidiary delivered pursuant to the
provisions hereof, to the performance by the Company of its covenants and other
obligations hereunder, and to the following further conditions:

               (a)    Effectiveness of Registration Statement. The Registration
     Statement, including any Rule 462(b) Registration Statement, has become
     effective under the 1933 Act and no stop order suspending the effectiveness
     of the Registration Statement shall have been issued under the 1933 Act or
     proceedings therefor initiated or threatened by the Commission, and any
     request on the part of the Commission for

                                      11
<PAGE>
 
     additional information shall have been complied with to the reasonable
     satisfaction of counsel to the Underwriters. A prospectus containing
     information relating to the description of the Debt Securities, the
     specific method of distribution and similar matters shall have been filed
     with the Commission in accordance with Rule 424(b)(1), (2), (3), (4) or
     (5), as applicable (or any required post-effective amendment providing such
     information shall have been filed and declared effective in accordance with
     the requirements of Rule 430A), or, if the Company has elected to rely upon
     Rule 434 of the 1933 Act Regulations, a Term Sheet including the Rule 434
     Information shall have been filed with the Commission in accordance with
     Rule 424(b)(7).

               (b)    Opinion of Counsel for Company. At Closing Time, Merrill
     Lynch shall have received the favorable opinion, dated as of Closing Time,
     of Womble Carlyle Sandridge & Rice, counsel for the Company, in form and
     substance satisfactory to counsel for the Underwriters, together with
     signed or reproduced copies of such letter for each of the other
     Underwriters, to the effect set forth in Exhibit B hereto and to such
     further effect as counsel to the Underwriters may reasonably request.

               (c)    Opinion of Counsel for Underwriters. At Closing Time,
     Merrill Lynch shall have received the favorable opinion, dated as of
     Closing Time, of Gibson, Dunn & Crutcher, counsel for the Underwriters,
     together with signed or reproduced copies of such letter for each of the
     other Underwriters, with respect to the matters set forth in (1), (5) to
     (8), (9) (solely as to the information in the Prospectus under "Description
     of the Debt Securities" or any caption purporting to describe any such
     Securities), (15), (16) and the penultimate paragraph of Exhibit B hereto.
     In giving such opinion, such counsel may rely, as to all matters governed
     by the laws of jurisdictions other than the law of the State of New York,
     the federal law of the United States and the General Corporation Law of the
     State of Delaware, upon the opinions of counsel satisfactory to Merrill
     Lynch. Without limiting the generality of the foregoing, such counsel may
     rely upon the opinion of Womble Carlyle Sandridge & Rice with respect to
     all matters governed by the laws of the State of North Carolina. Such
     counsel may also state that, insofar as such opinion involves factual
     matters, they have relied, to the extent they deem proper, upon
     certificates of officers of the Company and its subsidiaries and
     certificates of public officials.

               (d)    Officers' Certificate. At Closing Time, there shall not
     have been, since the date of the applicable Terms Agreement or since the
     respective dates as of which information is given in the Prospectus, any
     material adverse change in the condition, financial or otherwise, or in the
     earnings, business affairs or business prospects of the Company and its
     subsidiaries considered as one enterprise, whether or not arising in the
     ordinary course of business, and Merrill Lynch shall have received a
     certificate of the President or a Vice President of the Company and of the
     chief financial officer or chief accounting officer of the Company, dated
     as of Closing Time, to the effect that (i) there has been no such material
     adverse change, (ii) the 

                                      12
<PAGE>
 
     representations and warranties in Section 1 are true and correct with the
     same force and effect as though expressly made at and as of the Closing
     Time, (iii) the Company has complied with all agreements and satisfied all
     conditions on its part to be performed or satisfied at or prior to the
     Closing Time, and (iv) no stop order suspending the effectiveness of the
     Registration Statement has been issued and no proceedings for that purpose
     have been initiated or threatened by the Commission.

               (e)    Accountant's Comfort Letter.  At the time of the execution
     of the applicable Terms Agreement, Merrill Lynch shall have received from
     Arthur Andersen & Co. L.L.P. a letter dated such date, in form and
     substance satisfactory to Merrill Lynch, together with signed or reproduced
     copies of such letter for each of the other Underwriters, containing
     statements and information of the type ordinarily included in accountants'
     "comfort letters" to underwriters with respect to the financial statements
     and certain financial information contained in the Registration Statement
     and the Prospectus.

               (f)    Bring-down Comfort Letter. At Closing Time, Merrill Lynch
     shall have received from Arthur Andersen & Co. L.L.P. a letter, dated as of
     Closing Time, to the effect that they reaffirm the statements made in the
     letter furnished pursuant to subsection (e) of this Section 5, except that
     the specified date referred to shall be a date not more than three business
     days prior to the Closing Time.

               (g)    Ratings. At Closing Time, the Debt Securities shall have
     the ratings accorded by any "nationally recognized statistical rating
     organization", as defined by the Commission for purposes of Rule 436(g)(2)
     of the 1933 Act Regulations, if and as specified in the applicable Terms
     Agreement, and the Company shall have delivered to Merrill Lynch a letter,
     dated as of such date, from each such rating organization, or other
     evidence satisfactory to Merrill Lynch, confirming that the Debt Securities
     have such ratings. Since the time of execution of such Terms Agreement,
     there shall not have occurred a downgrading in the rating assigned to the
     Debt Securities or any of the Company's other securities by any such rating
     organization, and no such rating organization shall have publicly announced
     that it has under surveillance or review, with possible negative
     implications, its rating of the Debt Securities or any of the Company's
     other securities.

               (h)    Approval of Listing. At Closing Time, the Debt Securities
     shall have been approved for listing, subject only to official notice of
     issuance, if and as specified in the applicable Terms Agreement.

               (i)    No Objection. If the Registration Statement or an
     offering of Debt Securities has been filed with the NASD for review, the
     NASD shall not have raised any objection with respect to the fairness and
     reasonableness of the underwriting terms and arrangements.

               (j)    Additional Documents. At Closing Time, counsel for the
     Underwriters shall have been furnished with such documents and opinions as
     they may reasonably require for the purpose of enabling them to pass upon
     the issuance and sale of the Debt Securities as herein contemplated, or in
     order to evidence the accuracy of any of the representations or warranties,
     or the fulfillment of any of the conditions, herein contained; and all
     proceedings taken by the Company in connection with the issuance and sale
     of the Debt Securities as herein contemplated shall be satisfactory in form
     and substance to Merrill Lynch and counsel for the Underwriters.

               (k)    Termination of Terms Agreement. If any condition
     specified in this Section 5 shall not have been fulfilled when and as
     required to be fulfilled, the applicable Terms Agreement may be terminated
     by Merrill Lynch by notice to the Company at any time at or prior to the
     Closing Time and such termination shall be without liability of any party
     to any other party except as provided in Section 4 and except that Sections
     1, 6 and 7 shall survive any such termination and remain in full force and
     effect.

          SECTION 6.  Indemnification.
                      --------------- 

          (a)  Indemnification of Underwriters. The Company agrees to indemnify

     alleged untrue statement of a material fact contained in the Registration
     Statement (or any amendment thereto), including the Rule 430A Information
     and the Rule 434 Information deemed to be a part thereof, if applicable, or
     the omission or alleged omission therefrom of a material fact required to

     statement of a material fact included in any preliminary prospectus or the
     Prospectus (or any amendment or supplement thereto), or the omission or
     alleged omission therefrom of a material fact necessary in order to make
     the statements therein, in the light of the circumstances under which they

Underwriter through Merrill Lynch expressly for use in the Registration
Statement (or any amendment thereto), including the 430A Information and the
Rule 434 Information deemed to be a part thereof, if applicable, or any
preliminary prospectus or the Prospectus (or any amendment or supplement
thereto).

          (b)  Indemnification of Company, Directors and Officers.  Each
Underwriter severally agrees to indemnify and hold harmless the Company, its
directors, each of its officers who signed the Registration Statement, and each
person, if any, who controls the Company within the meaning of Section 15 of the
1933 Act or Section 20 of the 1934 Act against any and all loss, liability,
claim, damage and expense described in the indemnity contained in subsection (a)
of this Section, as incurred, but only with respect to untrue statements or
omissions, or alleged untrue statements or omissions, made in the Registration
Statement (or any amendment thereto), including the Rule 430A Information and
the Rule 434 Information deemed to be a part thereof, if applicable, or any
preliminary prospectus or the Prospectus (or any amendment or supplement
thereto) in reliance upon and in conformity with written information furnished
to the Company by such Underwriter through Merrill Lynch expressly for use in
the Registration Statement (or any amendment thereto) or such preliminary
prospectus or the Prospectus (or any amendment or supplement thereto).

          (c)  Actions against Parties; Notification.  Each indemnified party
shall give notice as promptly as reasonably practicable to each indemnifying
party of any action commenced against it in respect of which indemnity may be
sought hereunder, but failure to so notify an indemnifying party shall not
relieve such indemnifying party from any liability hereunder to the extent it is
not materially prejudiced as a result thereof and in any event shall not relieve
it from any liability which it may have otherwise than on account of this
indemnity agreement. In the case of parties indemnified pursuant to Section 6(a)
above, counsel to the indemnified parties shall be selected by Merrill Lynch
with the consent of the Company (which consent shall not be unreasonably
withheld), and, in the case of parties indemnified pursuant to Section 6(b)
above, counsel to the indemnified parties shall be selected by the Company with
the consent of the Merrill Lynch (which consent shall not be unreasonably
withheld). An indemnifying party may participate at its own expense in the
defense of any such action; provided, however, that counsel to the indemnifying
party shall not (except with the consent of the indemnified party) also be
counsel to the indemnified party. In no event shall the indemnifying parties be
liable for fees and expenses of more than one counsel (in addition to

                                      15
<PAGE>
 
any local counsel) separate from their own counsel for all indemnified parties
in connection with any one action or separate but similar or related actions in
the same jurisdiction arising out of the same general allegations or
circumstances. No indemnifying party shall, without the prior written consent of
the indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any litigation, or any investigation or proceeding by
any governmental agency or body, commenced or threatened, or any claim
whatsoever in respect of which indemnification or contribution could be sought
under this Section 6 or Section 7 hereof (whether or not the indemnified parties
are actual or potential parties thereto), unless such settlement, compromise or
consent (i) includes an unconditional release of each indemnified party from all
liability arising out of such litigation, investigation, proceeding or claim and
(ii) does not include a statement as to or an admission of fault, culpability or
a failure to act by or on behalf of any indemnified party.

          (d)  Settlement without Consent if Failure to Reimburse. If at any
time an indemnified party shall have requested an indemnifying party to
reimburse the indemnified party for fees and expenses of counsel for which the
indemnifying party is liable under this Section 6, such indemnifying party
agrees that it shall be liable for any settlement of the nature contemplated by
Section 6(a)(2) effected without its written consent if (i) such settlement is
entered into more than 45 days after receipt by such indemnifying party of the
aforesaid request, (ii) such indemnifying party shall have received notice of
the terms of such settlement at least 30 days prior to such settlement being
entered into and (iii) such indemnifying party shall not have reimbursed such
indemnified party in accordance with such request prior to the date of such
settlement.

          SECTION 7.  Contribution. If the indemnification provided for in
                      ------------
Section 6 hereof is for any reason unavailable to or insufficient to hold
harmless an indemnified party in respect of any losses, liabilities, claims,
damages or expenses referred to therein, then each indemnifying party shall
contribute to the aggregate amount of such losses, liabilities, claims, damages
and expenses incurred by such indemnified party, as incurred, (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company, on the one hand, and the Underwriters, on the other hand, from the
offering of the Debt Securities pursuant to the applicable Terms Agreement or
(ii) if the allocation provided by clause (i) is not permitted by applicable
law, in such proportion as is appropriate to reflect not only the relative
benefits referred to in clause (i) above but also the relative fault of the
Company, on the one hand, and of the Underwriters, on the other hand, in
connection with the statements or omissions which resulted in such losses,
liabilities, claims, damages or expenses, as well as any other relevant
equitable considerations.

          The relative benefits received by the Company, on the one hand, and
the Underwriters, on the other hand, in connection with the offering of the Debt
Securities pursuant to the applicable Terms Agreement shall be deemed to be in
the same respective proportions as the total net proceeds from the offering of
such Debt Securities (before deducting expenses) received by the Company and the
total underwriting discount received by the Underwriters; in each case as set
forth on the cover of the Prospectus, or, if Rule 434 is 

                                      16
<PAGE>
 
used, the corresponding location on the Term Sheet bears to the aggregate 
initial public offering price of such Debt Securities as set forth on such
cover.

          The relative fault of the Company, on the one hand, and the
Underwriters, on the other hand, shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by the Company or by the Underwriters and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

          The Company and the Underwriters agree that it would not be just and
equitable if contribution pursuant to this Section 7 were determined by pro rata
allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to above in this Section 7. The aggregate
amount of losses, liabilities, claims, damages and expenses incurred by an
indemnified party and referred to above in this Section 7 shall be deemed to
include any legal or other expenses reasonably incurred by such indemnified
party in investigating, preparing or defending against any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever based upon any such untrue or alleged untrue
statement or omission or alleged omission.

          Notwithstanding the provisions of this Section 7, no Underwriter shall
be required to contribute any amount in excess of the amount by which the total
price at which the Debt Securities underwritten by it and distributed to the
public were offered to the public exceeds the amount of any damages which such
Underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission.

          No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the 1933 Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation.

          For purposes of this Section 7, each person, if any, who controls an
Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act shall have the same rights to contribution as such Underwriter, and
each director of the Company, each officer of the Company who signed the
Registration Statement, and each person, if any, who controls the Company within
the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall
have the same rights to contribution as the Company. The Underwriters'
respective obligations to contribute pursuant to this Section 7 are several in
proportion to the aggregate principal amount of Debt Securities set forth
opposite their respective names in the applicable Terms Agreement, and not
joint.

          SECTION 8.  Representations, Warranties and Agreements to Survive
                      ----------------------------------------------------- 
Delivery.  All representations, warranties and agreements contained in this
- --------
Underwriting Agreement or the applicable Terms Agreement or in certificates of
officers of the Company submitted pursuant hereto or thereto shall remain
operative and in full force and effect, 

                                      17
<PAGE>
 
regardless of any investigation made by or on behalf of any Underwriter or
controlling person, or by or on behalf of the Company, and shall survive
delivery of and payment for the Debt Securities.

          SECTION 9.  Termination.
                      ----------- 

          (a)  Underwriting Agreement. This Underwriting Agreement (excluding
the applicable Terms Agreement) may be terminated for any reason at any time by
the Company or by Merrill Lynch upon the giving of 30 days' prior written notice
of such termination to the other party hereto.

          (b)  Terms Agreement. Merrill Lynch may terminate the applicable Terms
Agreement, by notice to the Company, at any time at or prior to the Closing
Time, if (i) there has been, since the time of execution of such Terms Agreement
or since the respective dates as of which information is given in the
Prospectus, any material adverse change in the condition, financial or
otherwise, or in the earnings, business affairs or business prospects of the
Company and its subsidiaries considered as one enterprise, whether or not
arising in the ordinary course of business, or (ii) there has occurred any
material adverse change in the financial markets in the United States or, if the
Debt Securities are denominated or payable in, or indexed to, one or more
foreign or composite currencies, in the international financial markets, or any
outbreak of hostilities or escalation thereof or other calamity or crisis or any
change or development involving a prospective change in national or
international political, financial or economic conditions, in each case the
effect of which is such as to make it, in the judgment of Merrill Lynch,
impracticable to market the Debt Securities or to enforce contracts for the sale
of the Debt Securities, or (iii) trading in any securities of the Company has
been suspended or limited by the Commission or the New York Stock Exchange, or
if trading generally on the New York Stock Exchange or the American Stock
Exchange or in the over-the-counter market has been suspended or limited, or
minimum or maximum prices for trading have been fixed, or maximum ranges for
prices have been required, by either of said exchanges or by such system or by
order of the Commission, the NASD or any other governmental authority, or (iv) a
banking moratorium has been declared by either Federal or New York authorities
or, if the Debt Securities are denominated or payable in, or indexed to, one or
more foreign or composite currencies, by the relevant authorities in the related
foreign country or countries.

          (c)  Liabilities. If this Underwriting Agreement or the applicable
Terms Agreement is terminated pursuant to this Section 9, such termination shall
be without liability of any party to any other party except as provided in
Section 4 hereof, and provided further that Sections 1, 6 and 7 shall survive
such termination and remain in full force and effect.

          SECTION 10.  Default by One or More of the Underwriters. If one or
                       ------------------------------------------         
more of the Underwriters shall fail at the Closing Time to purchase the Debt
Securities which it or they are obligated to purchase under the applicable Terms
Agreement (the "Defaulted Securities"), then Merrill Lynch shall have the right,
within 24 hours thereafter, to make arrangements for one or more of the 
non-defaulting Underwriters, or any other underwriters,

                                      18
<PAGE>
 
to purchase all, but not less than all, of the Defaulted Securities in such
amounts as may be agreed upon and upon the terms herein set forth; if, however,
Merrill Lynch shall not have completed such arrangements within such 24-hour
period, then:

               (a)    if the aggregate principal amount of Defaulted Securities
     does not exceed 10% of the aggregate principal amount of Debt Securities to
     be purchased on such date pursuant to such Terms Agreement, the non-
     defaulting Underwriters shall be obligated, severally and not jointly, to
     purchase the full amount thereof in the proportions that their respective
     underwriting obligations under such Terms Agreement bear to the
     underwriting obligations of all non-defaulting Underwriters, or

               (b)    if the aggregate principal amount of Defaulted Securities
     exceeds 10% of the aggregate principal amount of Debt Securities to be
     purchased on such date pursuant to such Terms Agreement, such Terms
     Agreement shall terminate without liability on the part of any non-
     defaulting Underwriter.

          No action taken pursuant to this Section 10 shall relieve any
defaulting Underwriter from liability in respect of its default.

          In the event of any such default which does not result in a
termination of the applicable Terms Agreement, either Merrill Lynch or the
Company shall have the right to postpone the Closing Time for a period not
exceeding seven days in order to effect any required changes in the Registration
Statement or the Prospectus or in any other documents or arrangements.

          SECTION 11.  Notices.  All notices and other communications hereunder
                       -------
shall be in writing and shall be deemed to have been duly given if mailed or
transmitted by any standard form of telecommunication.  Notices to the
Underwriters shall be directed to Merrill Lynch at World Financial Center, North
Tower, New York, New York 10281-1201 attention of                ; and notices

                       -------
Terms Agreement shall each inure to the benefit of and be binding upon the
Company, Merrill Lynch and, upon execution of such Terms Agreement, any other
Underwriters and their respective successors.  Nothing expressed or mentioned in
this Underwriting Agreement or such Terms Agreement is intended or shall be
construed to give any person, firm or corporation, other than the Underwriters
and the Company and their respective successors and the controlling persons and
officers and directors referred to in Sections 6 and 7 hereof and their heirs
and legal representatives, any legal or equitable right, remedy or claim under
or in respect of this Underwriting Agreement or such Terms Agreement or any

thereto and their respective successors, and said controlling persons and

of no other person, firm or corporation. No purchaser of Debt Securities from
any Underwriter shall be deemed to be a successor by reason merely of such
purchase.

          SECTION 13.  GOVERNING LAW AND TIME. THIS UNDERWRITING AGREEMENT AND
                       ----------------------
ANY APPLICABLE TERMS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF NEW YORK. SPECIFIED TIMES OF DAY REFER TO NEW YORK

                     FORM OF OPINION OF COMPANY'S COUNSEL
                          TO BE DELIVERED PURSUANT TO

as a corporation in good standing under the laws of the State of North Carolina.

          (2)   The Company has corporate power and authority to own, lease and
operate its properties and to conduct its business as described in the
Prospectus and to enter into and perform its obligations under, or as
contemplated under, the Underwriting Agreement and the applicable Terms
Agreement.

          (3)   The Company is duly registered as a bank holding company under
the Bank Holding Company Act of 1956, as amended.

          (4)   Each Subsidiary is validly existing as a corporation in good

          (5)   The Underwriting Agreement and the applicable Terms Agreement
have been duly authorized, executed and delivered by the Company.

          (6)   The Debt Securities have been duly authorized by the Company for
issuance and sale pursuant to the Underwriting Agreement and the applicable
Terms Agreement. The Debt Securities, when issued and authenticated in the
manner provided for in the applicable Indenture and delivered against payment of
the consideration therefor specified in such Terms Agreement, will constitute
valid and legally binding obligations of the Company, enforceable against the
Company in accordance with their terms, except as the enforcement thereof may be
limited by bankruptcy, insolvency, reorganization, moratorium or other similar
laws relating to or affecting creditors' rights generally or by general
equitable principles, and except further as enforcement thereof may be limited
by (A) requirements that a claim with respect to any Debt Securities denominated
other than in U.S. dollars (or a foreign or composite currency judgment in
respect of such claim) be converted into U.S. dollars at a rate of exchange
prevailing on a date determined pursuant to applicable law or (B) governmental
authority to limit, delay or prohibit the making of payments outside the United
States. The Debt Securities are in the form contemplated by, and each registered
holder thereof is entitled to the benefits of, the applicable Indenture.

          (7)   The [Each] applicable Indenture has been duly authorized,
executed and delivered by the Company and (assuming due authorization, execution
and delivery

                                      B-1
<PAGE>
 
thereof by the applicable Trustee) constitutes a valid and legally binding
agreement of the Company, enforceable against the Company in accordance with its
terms, except as the enforcement thereof may be limited by bankruptcy,
insolvency, reorganization, moratorium or other similar laws relating to or
affecting creditors' rights generally or by general equitable principles.

          (8)   The Debt Securities being sold pursuant to the applicable Terms
Agreement and the [each] applicable Indenture conform, in all material respects,
to the statements relating thereto contained in the Prospectus and are in
substantially the form filed or incorporated by reference, as the case may be,
as an exhibit to the Registration Statement.

          (9)   The information in the Prospectus under "Description of the Debt
Securities" or any caption purporting to describe any such Debt Securities,
"Certain Regulatory Considerations" and in the Annual Report on Form 10-K under
"__________", to the extent that it constitutes matters of law, summaries of
legal matters, the Company's charter and bylaws or legal proceedings, or legal
conclusions, has been reviewed by us and is correct in all material respects.

          (10)  To the best of our knowledge, neither the Company nor any of the
Subsidiaries is in violation of its charter or by-laws and no default by the
Company or any subsidiary exists in the due performance or observance of any
material obligation, agreement, covenant or condition contained in any contract,
indenture, mortgage, loan agreement, note, lease or other agreement or
instrument that is described in the Registration Statement or the Prospectus or
filed or incorporated by reference as an exhibit to the Registration Statement.

          (11)  The execution, delivery and performance of the Underwriting
Agreement, the applicable Terms Agreement and the [each] applicable Indenture
and the consummation of the transactions contemplated in the Underwriting
Agreement and such Terms Agreement and in the Registration Statement and the
Prospectus (including the issuance and sale of the Debt Securities) and
compliance by the Company with its obligations thereunder do not and will not,
whether with or without the giving of notice or passage of time or both,
conflict with or constitute a breach of, or default or Repayment Event under, or
result in the creation or imposition of any lien, charge or encumbrance upon any
property or assets of the Company or any Subsidiary pursuant to, any contract,
indenture, mortgage, deed of trust, loan or credit agreement, note, lease or any
other agreement or instrument to which the Company or any subsidiary is a party
or by which it or any of them may be bound, or to which any of the assets,
properties or operations of the Company or any subsidiary is subject, and that
is filed as an exhibit to the Company's Annual Report on Form 10-K for the year
ended December 31, 1995 or to the Registration Statement except for such
conflicts, breaches, defaults, events or liens, charges or encumbrances that
would not result in a Material Adverse Effect, nor will such action result in
any violation of the provisions of the charter or by-laws of the Company or any
Subsidiary or any applicable law, statute, rule, regulation, judgment, order,
writ or decree, known to us, of any government, government instrumentality or
court, domestic or foreign, having jurisdiction over the Company or any
subsidiary or any of their assets, properties or operations (provided that we
are not rendering 

                                      B-2
<PAGE>
 
any opinion in this paragraph 11 with respect to state securities or blue sky
laws or the disclosure provisions of the 1933 Act or the 1934 Act).

          (12)  To the best of our knowledge, there is no action, suit,
proceeding, inquiry or investigation before or by any court or governmental
agency or body, domestic or foreign, now pending or threatened, against or
affecting the Company or any subsidiary thereof which is required to be
disclosed in the Registration Statement and the Prospectus (other than as stated
therein), or which might reasonably be expected to result in a Material Adverse
Effect, or which might reasonably be expected to materially and adversely affect
the assets, properties or operations thereof or the consummation of the
Underwriting Agreement, the applicable Terms Agreement or the [any] applicable
Indenture or the transactions contemplated therein.

          (13)  All descriptions in the Prospectus of contracts and other
documents to which the Company or the Subsidiaries are a party are accurate in
all material respects.  To the best of our knowledge, there are no franchises,
contracts, indentures, mortgages, loan agreements, notes, leases or other
instruments required to be described or referred to in the Registration
Statement or to be filed as exhibits thereto other than those described or
referred to therein or filed or incorporated by reference as exhibits thereto,
and the descriptions thereof or references thereto are correct in all material
respects.

          (14)  To the best of our knowledge, there are no statutes or
regulations that are required to be described in the Prospectus that are not
described as required.

          (15)  The Registration Statement has been declared effective under the
1933 Act. Any required filing of the Prospectus pursuant to Rule 424(b) has been
made in the manner and within the time period required by Rule 424(b).  To the
best of our knowledge, no stop order suspending the effectiveness of the
Registration Statement has been issued under the 1933 Act or proceedings
therefor initiated or threatened by the Commission.

          (16)  The Registration Statement, [the Rule 430A Information,] [the
Rule 434 Information,] the Prospectus, excluding the documents incorporated by
reference therein, and each amendment or supplement to the Registration
Statement and Prospectus, excluding the documents incorporated by reference
therein, as of their respective effective or issue dates (other than the
financial statements and supporting schedules included therein and each
Trustee's Statement of Eligibility on Form T-1 (the "Form T-1s"), as to which no
opinion need be rendered) complied as to form in all material respects with the
requirements of the 1933 Act and the 1933 Act Regulations.

          (17)  The documents incorporated by reference in the Prospectus (other
than the financial statements and supporting schedules therein, as to which no
opinion need be rendered), when they were filed with the Commission complied as
to form in all material respects with the requirements of the 1934 Act and the
rules and regulations of the Commission thereunder.

                                      B-3
<PAGE>
 
          (19)  No filing with, or authorization, approval, consent, license,
order, registration, qualification or decree of, any court or governmental
authority or agency is necessary or required for the performance by the Company
of its obligations under the Underwriting Agreement or the applicable Terms
Agreement or in connection with the transactions contemplated under the
Underwriting Agreement, such Terms Agreement or the [any] applicable Indenture
other than under the 1933 Act, the 1933 Act Regulations, the 1939 Act and the
1939 Act Regulations, which have been obtained, or as may be required under
state securities or blue sky laws.

          Nothing has come to our attention that would lead us to believe that
the Registration Statement (except for financial statements and schedules and
other financial data included therein and for the Form T-1s, as to which we make
no statement), at the time the Registration Statement or any post-effective
amendment thereto (including the filing of the Company's Annual Report on Form
10-K with the Commission) became effective or at the date of the applicable
Terms Agreement, contained an untrue statement of a material fact or omitted to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading or that the Prospectus or any amendment or
supplement thereto (except for financial statements and schedules and other
financial data included therein as to which we make no statement), at the time
the Prospectus was issued, at the time any such amended or supplemented
prospectus was issued or at the Closing Time, included or includes an untrue
statement of a material fact or omitted 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, such counsel may rely as to matters of fact
(but not as to legal conclusions), to the extent they deem proper, on
certificates of responsible officers of the Company and public officials. In
rendering the opinion set forth in paragraph (3) and the second sentence of
paragraph (5) above, such counsel may rely exclusively upon certificates of
appropriate officials of each such jurisdiction. Such opinion shall not state
that it is to be governed or qualified by, or that it is otherwise subject to,
any treatise, written policy or other document relating to legal opinions,
including, without limitation, the Legal Opinion Accord of the ABA Section of
Business Law (1991).

          In rendering such opinion, such counsel may rely, as to all matters
governed by the laws of jurisdictions other than the law of the State of North
Carolina, the federal law of the United States and the General Corporation Law
of the State of Delaware, upon the opinions of counsel satisfactory to Merrill
Lynch. Without limiting the generality of the foregoing, such counsel may rely
upon the opinion of counsel for the Underwriters with respect to all matters
governed by the laws of the State of New York. Such counsel may also state that,
insofar as such opinion involves factual matters, they have relied, to the
extent they deem proper, upon certificates of officers of the Company and its
subsidiaries and certificates of public officials.

         FORM OF ACCOUNTANTS' COMFORT LETTER PURSUANT TO SECTION 5(e)

We are independent public accountants with respect to the Company within the
meaning of the 1933 Act and the applicable published 1933 Act Regulations

               (i)    in our opinion, the audited financial statements [and the
     related financial statement schedules] included or incorporated by
     reference in the Registration Statement and the Prospectus comply as to
     form in all material respects with the applicable accounting requirements
     of the 1933 Act and the published rules and regulations thereunder;

               (ii)   on the basis of procedures (but not an examination in
     accordance with generally accepted auditing standards) consisting of a
     reading of the unaudited interim consolidated financial statements of the
     Company for the [three month periods ended _________, 19__ and _________,
     19__, the three and six month periods ended _________, 19__ and _________,
     19__, and the three and nine month periods ended _________, 19__ and
     _________, 19__, included or incorporated by reference in the Registration
     Statement and the Prospectus (collectively, the "10-Q Financials")] [, a
     reading of the unaudited interim consolidated financial statements of the
     Company for the _____-month periods ended _________, 19__ and _________,
     19___, included in the Registration Statement and the Prospectus (the
     "_____-month financials")] [, a reading of the latest available unaudited
     interim consolidated financial statements of the Company], a reading of the
     minutes of all meetings of the stockholders and directors of the Company
     and its subsidiaries and the _______ and ___________ Committees of the
     Company's Board of Directors and any subsidiary committees since [day after
     end of last audited period], inquiries of certain officials of the Company
     and its subsidiaries responsible for financial and accounting matters, a
     review of interim financial information in accordance with standards
     established by the American Institute of Certified Public Accountants in
     Statement on Auditing Standards No. 71, Interim Financial Information ("SAS
     71"), with respect to the [description of relevant periods including all
     interim unaudited condensed consolidated financial statements included or
     incorporated by reference in the Registration Statement and the Prospectus
     and such other inquiries and procedures as may be specified in such letter,
     nothing came to our attention that caused us to believe that:

                      [(A)   the 10-Q Financials incorporated by reference in
          the Registration Statement and the Prospectus do not comply as to form
          in all material respects with the applicable accounting requirements
          of the 1934 Act and the 1934 Act Regulations applicable to unaudited
          financial statements included in Form 10-Q or any material
          modifications should be made to the 10-Q Financials incorporated by
          reference in the Registration Statement and

          accounting principles;]

          Registration Statement and the Prospectus do not comply as to form in
          all material respects with the applicable accounting requirements of
          the 1933 Act and the 1933 Act Regulations applicable to unaudited
          interim financial statements included in registration statements or
          any material modifications should be made to the _____-month
          financials included in the Registration Statement and the Prospectus
          for them to be in conformity with generally accepted accounting
          principles;]

                      ( )    at [the most recent balance sheet date and at] a
          specified date not more than five days prior to the date of the
          applicable Terms Agreement, there was any change in the __________ of
          the Company and its subsidiaries or any decrease in the __________ of
          the Company and its subsidiaries or any increase in the __________ of
          the Company and its subsidiaries, in each case as compared with
          amounts shown in the latest balance sheet included in the Registration
          Statement and the Prospectus, except in each case for changes,
          decreases or increases that the Registration Statement and the
          Prospectus disclose have occurred or may occur; or

                      ( )    [for the period from _______, 19__ to _______, 19__
          and] for the period from _________, 19__ to a specified date not more
          than five days prior to the date of the applicable Terms Agreement,
          there was any decrease in _________, __________ or __________, in each
          case as compared with the comparable period in the preceding year,
          except in each case for any decreases that the Registration Statement
          and the Prospectus disclose have occurred or may occur;

               (iii) based upon the procedures set forth in clause (ii) above
     and a reading of the [Selected Financial Data] included in the Registration
     Statement and the Prospectus [and a reading of the financial statements
     from which such data were derived], nothing came to our attention that
     caused us to believe that the [Selected Financial Data] included in the
     Registration Statement and the Prospects do not comply as to form in all
     material respects with the disclosure requirements of Item 301 of
     Regulation S-K of the 1933 Act [, that the amounts included in the
     [Selected Financial Data] are not in agreement with the corresponding
     amounts in the audited consolidated financial statements for the respective
     periods or that the financial statements not included in the Registration
     Statement and the Prospectus from which certain of such data were derived
     are not in conformity with generally accepted accounting principles];

               (iv) we have compared the information in the Registration
     Statement and the Prospectus under selected captions with the disclosure
     requirements of 

                                   Annex I-2
<PAGE>
 
     Regulation S-K of the 1933 Act and on the basis of limited procedures
     specified herein, nothing came to our attention that caused us to believe
     that this information does not comply as to form in all material respects
     with the disclosure requirements of Items 302, 402 and 503(d),
     respectively, of Regulation S-K;

               [(v) based upon the procedures set forth in clause (ii) above, a
     reading of the unaudited financial statements of the Company for [the most
     recent period] that have not been included in the Registration Statement
     and the Prospectus and a review of such financial statements in accordance
     with SAS 71, nothing came to our attention that caused us to believe that
     the unaudited amounts for _____________ for the [most recent period] do not
     agree with the amounts set forth in the unaudited consolidated financial
     statements for those periods or that such unaudited amounts were not
     determined on a basis substantially consistent with that of the
     corresponding amounts in the audited consolidated financial statements;]

               [(vi)] [Include only if pro forma financial statements are
     included or incorporated by reference in the Registration Statement -- ] we
     are unable to and do not express any opinion on the [Pro Forma Combining
     Statement of Operations] (the "Pro Forma Statement") included in the
     Registration Statement and the Prospectus or on the pro forma adjustments
     applied to the historical amounts included in the Pro Forma Statement;
     however, for purposes of this letter we have:

                      (A)    read the Pro Forma Statement;

                      (B)    performed [an audit] [a review in accordance with
          SAS 71] of the financial statements to which the pro forma adjustments
          were applied;

                      (C)    made inquiries of certain officials of the Company
          who have responsibility for financial and accounting matters about the
          basis for their determination of the pro forma adjustments and whether
          the Pro Forma Statement complies as to form in all material respects
          with the applicable accounting requirements of Rule 11-02 of
          Regulation S-X; and

                      (D)    proved the arithmetic accuracy of the application
          of the pro forma adjustments to the historical amounts in the Pro
          Forma Statement; and

     on the basis of such procedures and such other inquiries and procedures as
     specified herein, nothing came to our attention that caused us to believe
     that the Pro Forma Statement included in the Registration Statement does
     not comply as to form in all material respects with the applicable
     requirements of Rule 11-02 of Regulation S-X or that the pro forma
     adjustments have not been properly applied to the historical amounts in the
     compilation of those statements; and

               [(vii)] in addition to the procedures referred to in clause (ii)
     above, we have performed other procedures, not constituting an audit, with
     respect to certain amounts, percentages, numerical data and financial
     information appearing in the Registration Statement and the Prospectus,
     which are specified herein, and have compared certain of such items with,
     and have found such items to be in agreement with, the accounting and
     financial records of the Company; and

               [(viii)] [Include only if financial forecasts are included in the
     Registration Statement --] in addition, we [comfort on a financial forecast
     that is included in the Registration Statement and the Prospectus].

and related coupons, if any, of each series and the certificates of
authentication on the Securities shall be in substantially the form as shall be
established as provided in Section 2.01 with such appropriate insertions,
omissions, substitutions and other variations as are required or permitted by
this Indenture, and may have such letters, numbers or other marks of
identification and such legends or endorsements placed thereon as may be
required to comply with any law or with any rules made pursuant thereto or with
any rules of any securities exchange or as may be determined consistently
herewith by the officers executing such Securities or coupons, as evidenced by
their execution of the Securities or coupons.  If the form of Securities of any
series or coupons (including any Global Security) is established by action taken
pursuant to a resolution of the Board of Directors, a copy of an appropriate
record of such action shall be certified by the Secretary or any Assistant
Secretary of the Company to have been duly adopted by the Board of Directors and
to be in full force and effect as of the date of such certificate, and shall be
delivered to the Trustee at or prior to the delivery of the Company Order
contemplated by Section 2.04(b) or the authentication and delivery of such

          SECTION 2.03.  Securities in Global Form.  (a) If Securities of a
                         -------------------------                            
series are issuable in whole or in part in global form, as specified in the
manner contemplated by Section 2.01, then, notwithstanding the provisions of
clause (11) of Section 2.01 or Section 2.04, such Global Security shall
represent such of the Outstanding Securities of such series as shall be
specified therein and may provide that it shall represent the aggregate amount
of Outstanding Securities from time to time endorsed thereon and that the
aggregate amount of Outstanding Securities represented thereby from time to time
may be reduced to reflect exchanges.  Any endorsement of a Global Security to
reflect the amount, or any increase or decrease in the amount, of Outstanding
Securities represented thereby shall be made in such manner and upon
instructions given by such Person or Persons as shall be specified in such
Global Security or in the Company Order to be delivered to the Trustee pursuant
to Section 2.04(b).

          (b)  The provisions of the last sentence of Section 2.05(b) shall
apply to any Securities represented by a Global Security if such Securities were
never issued and sold by the Company (whether because of failure of settlement
or otherwise) and the Company delivers to the Trustee the Global Security
together with written instructions with regard to the reduction in the principal
amount of Securities represented thereby, together with the written statement
contemplated by the last sentence of Section 2.05(b), notwithstanding the
absence of delivery of such Securities as contemplated thereby.

          (c)  Global Securities may be issued in either registered or bearer
form and in either temporary or permanent form.

          SECTION 2.04.  Denomination, Authentication and Dating of Securities.
                         -----------------------------------------------------
(a) Securities of each series shall be issuable in such form and denominations
as shall be specified in the form of Security for such series approved or
established pursuant to Section 2.02.  In the absence of any specification, as
provided in Section 2.01, with respect to the Securities of any series, the
Registered Securities of such series, if any, shall be issuable in denominations
of $1,000 and any integral multiple thereof and the Bearer Securities of such
series, if any, shall be issuable in the 

                                      12
<PAGE>

          (b)  At any time and from time to time after the execution and
delivery of this Indenture, the Company may deliver Securities of any series
executed by the Company to the Trustee for authentication. Except as otherwise
provided in this Article Two, the Trustee thereupon shall authenticate and
deliver such Securities in accordance with a Company Order; provided, however,
that in connection with its original issuance a Bearer Security may be delivered
only outside the United States and, except in the case of a temporary Global
Security, only if the Company or its agent shall have received from the Person
entitled to receive the Bearer Security a Bearer Security Tax Certificate and
only if the Company and the Trustee have no reason to know that such certificate
is false.

          (c)  To the extent authorized in or pursuant to a resolution of the
Board of Directors or established in an indenture supplemental hereto, such
Company Order may be electronically transmitted and may provide instructions as
to registration of holders, principal amounts, rates of interest, Stated
Maturities and other matters contemplated by such resolution of the Board of
Directors or supplemental indenture to be so instructed in respect thereof.

          (d)  In authenticating such Securities, and accepting the additional
responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive, and, subject to Section 5.01, shall be
fully protected in relying upon:

               (i)  a copy of the resolution or resolutions of the Board of
     Directors in or pursuant to which the terms and form of the Securities were
     established, certified by the Secretary or an Assistant Secretary of the
     Company to have been duly adopted by the Board of Directors and to be in
     full force and effect as of the date of such certificate;

              (ii)  an executed supplemental indenture, if any;

             (iii)  an Officers' Certificate delivered in accordance with
     Section 15.05; and

              (iv)  an Opinion of Counsel which shall state:

                                      13
<PAGE>
 
                    (A)  that the form of such Securities and coupons, if any,
          has been established by a supplemental indenture or by or pursuant to
          a resolution of the Board of Directors in accordance with Sections
          2.01 and 2.02 and in conformity with the provisions of this Indenture;

                    (B)  that the terms of such Securities and coupons, if any,
          have been established in accordance with Section 2.01 and in
          conformity with the other provisions of this Indenture;

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

                    (D)  that all conditions precedent, if any, provided for in
          this Indenture have been complied with; and

                    (E)  that the execution and delivery by the Company of such
          Securities and coupons, if any, do not conflict with any law,
          administrative regulation or court decree known by legal counsel
          furnishing the Opinion of Counsel to be applicable to the Company.

          (e)  If the Company shall establish pursuant to Section 2.01 that the
Securities of a series are to be issued in whole or in part in the form of one
or more Global Securities, then the Company shall execute and the Trustee, in
accordance with this Section 2.04 and the Company Order with respect to such
series, shall authenticate and deliver one or more Global Securities in
permanent or temporary form that (i) shall represent and shall be denominated in
an aggregate amount equal to the aggregate principal amount of the Outstanding
Securities of such series to be represented by one or more Global Securities,
(ii) shall be registered in the name of the Depositary for such Global Security
or Securities or the nominee of such Depositary and (iii) shall be delivered by
the Trustee to such Depositary or pursuant to such Depositary's instruction.

                                      14
<PAGE>
 
          (f)  The Trustee shall have the right to decline to authenticate and
deliver any Securities under this Section 2.04 if the Trustee, being advised by
counsel, determines that such action may not lawfully be taken or if the Trustee
in good faith by its board of directors or trustees, executive committee or a
trust committee of directors or trustees or vice presidents shall determine that
such action would expose the Trustee to personal liability to existing holders.

          (g)  Notwithstanding any contrary provision herein, if all Securities
of a series are not to be originally issued at one time, it shall not be
necessary for the Company to deliver to the Trustee a Company Order, Officers'
Certificate, resolution of the Board of Directors, supplemental indenture or
Opinion of Counsel otherwise required pursuant to Section 2.04(b) or Section
2.04(d) at or prior to the time of authentication of each Security of such
series if such documents are delivered to the Trustee or its agent at or prior
to the authentication upon original issuance of the first Security of such
series to be issued.  In such event, any subsequent request by the Company to
the Trustee to authenticate Securities of such series upon original issuance
shall constitute a representation and warranty by the Company that, as of the
date of such request, the statements made in the Officers' Certificate or other
certificates delivered pursuant to Section 2.04(d) shall be true and correct as
if made on such date.  A Company Order, Officers' Certificate, resolution of the
Board of Directors or supplemental indenture delivered by the Company to the
Trustee in the circumstances set forth in this Section 2.04(g) may provide that
Securities that are the subject thereof will be authenticated and delivered by
the Trustee or its agent on original issue from time to time in the aggregate
principal amount established for such series pursuant to such procedures
acceptable to the Trustee as may be specified from time to time by Company Order
upon the telephonic, electronic or written order of persons designated in such
Company Order, supplemental indenture or resolution of the Board of Directors
(any such telephonic or electronic instructions to be promptly confirmed in
writing by such persons) and that such persons are authorized to determine,
consistent with such Company Order, supplemental indenture or resolution of the
Board of Directors, such terms and conditions of said Securities as are
specified in such Company Order, supplemental indenture or resolution of the
Board of Directors.

          (h)  Each Depositary designated pursuant to clause (9) of Section 2.01
for a Global Security in registered form, at the time of its designation and at
all times while it serves as Depositary, shall be a clearing 

                                      15
<PAGE>
 
agency registered under the Securities Exchange Act of 1934 and any other
applicable statute or regulation.

          SECTION 2.05.  Execution of Securities.   (a) The Securities and the
                         -----------------------                                
related coupons shall be signed in the name and on behalf of the Company by the
manual or facsimile signature of its Chairman of the Board, its Chief Executive
Officer or its President or, in lieu thereof, of any Senior Vice President or
its Treasurer and attested by its Secretary, under its corporate seal (which may
be printed, engraved or otherwise reproduced thereon, by facsimile or
otherwise).  For the purpose of any such signature or attestation, the Company
may adopt and use the facsimile signature of any person who has been or is or
shall be such officer.

          (b)  No Security or appurtenant coupon shall be entitled to the
benefits of this Indenture or be valid or obligatory for any purpose unless such
security bears thereon a certificate of authentication substantially in the form
set forth in Section 2.02, manually executed by an authorized signatory of the
Trustee.  Such certificate by the Trustee upon any Security executed by the
Company shall be conclusive evidence that the Security so authenticated has been
duly authenticated and delivered under this Indenture.  Except as permitted by
Section 2.07, the Trustee shall not authenticate and deliver any Bearer Security
unless all appurtenant coupons for interest then matured have been detached and
canceled.  Notwithstanding the foregoing, if any Security or portions thereof
shall have been duly authenticated and delivered hereunder but never issued and
sold by the Company (whether because of failure of settlement or otherwise), and
the Company shall deliver such Security to the Trustee for cancellation as
provided in Section 2.10 together with a written statement stating that such
Security or portion thereof has never been issued and sold by the Company, for
all purposes of this Indenture such Security shall be deemed never to have been
authenticated and delivered hereunder and shall not be entitled to the benefits
of this Indenture.

          (c)  In case any officer of the Company whose manual or facsimile
signature appears on any of the Securities or coupons shall cease to be such
officer before the Securities or coupons so signed shall have been authenticated
and delivered by the Trustee, or disposed of by the Company, such Securities or
coupons nevertheless may be authenticated and delivered or disposed of as though
the person whose manual or facsimile signature appears on such Securities or
coupons had not ceased to be such officer of the Company; and any Security or
coupon may bear the manual or facsimile signature on behalf of the Company by
such 

                                      16
<PAGE>
 
persons as, at the actual date of the execution of such Security or coupon,
shall be the proper officers of the Company, although at the date of the
execution of this Indenture any such person was not such an officer.

          SECTION 2.06.  Exchange and Registration of Transfer of Securities.
                         --------------------------------------------------- 
(a) Registered Securities of any series may be exchanged for a like aggregate
principal amount of Registered Securities of other authorized denominations and
of like tenor and terms of the same series.  Registered Securities to be
exchanged shall be surrendered at the office or agency to be maintained by the
Company pursuant to Section 3.02 in each Place of Payment for such series of
Registered Securities, and the Company shall execute and cause to be registered,
and the Trustee shall authenticate and deliver in exchange therefor, the
Registered Security or Securities which the Securityholder making the exchange
shall be entitled to receive.

          (b)  For each series of Registered Securities, the Company shall cause
to be kept in at least one such office or agency a Security register (the
"Security Register") in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for registration of Registered Securities
and registration of transfer of Registered Securities as provided in this
Article Two.  Each such Security Register shall be in written form or in any
other form capable of being converted into written form within a reasonable
time.  At all reasonable times such Security Registers shall be open for
inspection by the Trustee.  Upon due presentment for registration of transfer of
any Registered Security of any series at any such office or agency, the Company
shall execute and register and the Trustee shall authenticate and deliver in the
name of the transferee or transferees a new Registered Security or Securities of
the same series and of like tenor and terms for an equal aggregate principal
amount.  Unless otherwise provided (pursuant to Section 2.01 or otherwise), the
Company initially appoints the Trustee, at the principal office of the Trustee,
as a Security registrar for each series of Registered Securities.

          (c)  All Registered Securities presented for registration of transfer
or for exchange or payment, if so required by the Company or the Trustee, shall
be duly endorsed by, or be accompanied by a written instrument or instruments of
transfer in form satisfactory to the Company and the Trustee duly executed by,
the holder or his attorney duly authorized in writing.

          (d)  To the extent specified in the manner provided by Section 2.01,
Registered Securities or Bearer 

                                      17
<PAGE>
 
Securities of any series may be issued in exchange for Bearer Securities (except
as otherwise specified in the manner contemplated by Section 2.01 with respect
to a Bearer Security in global form) of the same series, of any authorized
denomination and of like tenor and terms and aggregate principal amount, upon
surrender of the Bearer Securities to be exchanged at any office or agency
specified in the manner provided by Section 2.01, with all unmatured coupons and
all unpaid matured coupons thereto appertaining. If the holder of a Bearer
Security is unable to produce any such unmatured coupon or coupons or unpaid
matured coupon or coupons, 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 amount represented by 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 hold harmless each of them and any Paying Agent. If
thereafter the holder of such 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 3.02, interest
represented by coupons shall be payable only upon presentation and surrender of
those coupons at an office or agency located outside the United States. Whenever
any Securities are so surrendered for exchange, the Company shall execute, and
the Trustee shall authenticate and deliver, the Securities which the holder
making the exchange is entitled to receive.

          (e)  If at any time the Depositary for the Global Securities of a
series notifies the Company that it is unwilling or unable to continue as
Depositary for the Global Securities of such series or if at any time the
Depositary for the Registered Securities of such series shall no longer be
eligible under Section 2.03 because it no longer is a clearing agency registered
under the Securities Exchange Act of 1934 and any other applicable statute or
regulation, the Company shall appoint a successor Depositary with respect to the
Global Securities of such series.  If a successor Depositary for the Global
Securities of such series is not appointed by the Company within 90 days after
the Company receives such notice or becomes aware of such ineligibility, the
Company's election pursuant to Section 2.01(9) shall no longer be effective with
respect to the Securities of such series and the Company will execute, and the
Trustee, upon receipt of a Company Order for the authentication and delivery of
definitive Securities of such series, will authenticate and deliver Securities
of such series in definitive form in an aggregate principal amount equal to 

                                      18
<PAGE>
 
the principal amount of the Global Security or Securities representing such
series in exchange for such Global Security or Securities.

          (f)  The Company at any time and in its sole discretion may determine
that the Securities of any series issued in the form of one or more Global
Securities shall no longer be represented by such Global Security or Securities.
In such event the Company will execute, and the Trustee, upon receipt of a
Company Order for the authentication and delivery of definitive Securities of
such series, will authenticate and deliver, Securities of such series in
definitive form and in an aggregate principal amount equal to the principal
amount of the Global Security or Securities representing such series in exchange
for such Global Security or Securities.

          (g)  If specified by the Company pursuant to Section 2.01 with respect
to a series of Securities, the Depositary for such series of Securities may
surrender a Global Security for such series of Securities in exchange in whole
or in part for Securities of such series of like tenor and terms and in
definitive form on such terms as are acceptable to the Company and such
Depositary.  Thereupon the Company shall execute, and the Trustee shall
authenticate and deliver:

               (i)  to each Person specified by such Depositary a new Security
     or new Securities of the same series, of like tenor and terms and of any
     authorized denomination as requested by such Person in aggregate principal
     amount equal to and in exchange for such Person's beneficial interest in
     the Global Security; and

              (ii)  to such Depositary a new Global Security of like tenor and
     terms and in a denomination equal to the difference, if any, between the
     principal amount of the surrendered Global Security and the aggregate
     principal amount of Securities delivered to holders thereof.

          (h)  In any exchange provided for in Section 2.06(e), Section 2.06(f)
or Section 2.06(g), the Company will execute and the Trustee will authenticate
and deliver Securities (i) in definitive registered form in authorized
denominations, if the Securities of such series are issuable as Registered
Securities, (ii) in definitive bearer form in authorized denominations, with
unmatured coupons attached, if the Securities of such series are issuable as
Bearer Securities or (iii) as either Registered or Bearer Securities, if the
Securities of such series are issuable in either form; provided, however, that
(A) no definitive Bearer Security shall be delivered in exchange 

                                      19
<PAGE>
 
for a temporary Global Security unless the Company or its agent shall have
received from the person entitled to receive the definitive Bearer Security a
Bearer Security Tax Certificate, (B) delivery of a Bearer Security shall occur
only outside the United States and (C) no definitive Bearer Security will be
issued if the Company or the Trustee has reason to know that such certificate is
false.

          (i)  Upon the exchange of all of a Global Security for Securities in
certificated form, such Global Security shall be canceled by the Trustee.  The
exchange of any portion of a Global Security for Securities in certificated form
shall be subject to Section 2.03(a).  Registered Securities issued in exchange
for all or part of a Global Security shall be registered in such names and in
such authorized denominations as the Depositary for such Global Security,
pursuant to instructions from its direct or indirect participants or otherwise,
shall instruct the Trustee.  The Trustee shall deliver such Registered
Securities to the persons in whose names such Securities are so registered.  The
Trustee shall deliver Bearer Securities issued in exchange for all or part of a
Global Security to the persons, and in such authorized denominations, as the
Depositary for such Global Security, pursuant to instructions from its direct or
indirect participants or otherwise, shall instruct the Trustee; provided,
however, that (A) no definitive Bearer Security shall be delivered in exchange
for all or part of a temporary Global Security unless the Company or its agent
shall have received from the person entitled to receive the definitive Bearer
Security a Bearer Security Tax Certificate, (B) delivery of a Bearer Security
shall occur only outside the United States and (C) no definitive Bearer Security
will be issued if the Company or the Trustee has reason to know that any such
certificate is false.

          (j)  No service charge shall be made for any exchange or registration
of transfer of Securities, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any such exchange or registration of transfer.

          (k)  The Company shall not be required (i) to issue, register the
transfer of or exchange Securities of any particular series during a period
beginning at the opening of business 15 days before the day of the mailing of a
notice of redemption of Securities of such series selected for redemption under
Section 10.03 and ending at the close of business on the day of such mailing,
(ii) to register the transfer of or exchange any Registered Security so selected
for redemption in whole or in part, except the unredeemed 

                                      20
<PAGE>
 
portion of any Registered Security being redeemed in part or (iii) to exchange
any Bearer Security so selected for redemption except that such a Bearer
Security may be exchanged for a Registered Security of that series, provided
that such Registered Security shall be surrendered immediately for redemption
with written instruction for payment consistent with the provisions of this
Indenture.

          (l)  Notwithstanding anything herein to the contrary:  the exchange of
Bearer Securities for Registered Securities shall be subject to applicable laws
and regulations in effect at the time of exchange; and neither the Company nor
the Trustee or any Security registrar shall exchange any Bearer Securities into
Registered Securities if it has received an Opinion of Counsel that as a result
of such exchanges the Company could suffer adverse consequences under the United
States Federal income tax laws and regulations then in effect and the Company
has delivered to the Trustee a Company Order directing the Trustee not to make
such exchanges thereafter unless and until the Trustee receives a subsequent
Company Order to the contrary.  The Company shall deliver copies of such Company
Order to the Security registrar.

          SECTION 2.07.  Mutilated, Destroyed, Lost or Stolen Securities.
                         -----------------------------------------------     
(a) In case any temporary or definitive Security of any series or any related
coupon shall become mutilated or be destroyed, lost or stolen, the Company in
its discretion may execute, and upon its request and in the absence of notice to
the Company and the Trustee that such Security or coupon has been acquired by a
bona fide purchaser, the Trustee shall authenticate and deliver a new Security
of the same series or related coupon, of equal aggregate principal amount and of
like tenor and terms bearing a number not contemporaneously outstanding, in
exchange and substitution for the mutilated Security or coupon, or in lieu of
and in substitution for the Security or coupon so destroyed, lost or stolen.  In
every case the applicant for a substituted Security or coupon shall furnish to
the Company and to the Trustee such security or indemnity as may be required by
them to hold each of them harmless, and, in every case of destruction, loss or
theft, the applicant also shall furnish to the Company and to the Trustee
evidence to their satisfaction of the destruction, loss or theft of such
security or coupon and of the ownership of such Security or coupon.

          (b)  The Trustee may authenticate any such substitute Security and
deliver the same upon the written request or authorization of any officer of the
Company.  Upon the issuance of any substitute Security or coupon, the Company
may require the payment of a sum sufficient to cover 

                                      21
<PAGE>
 
any tax or other governmental charge that may be imposed in relation thereto and
any other reasonable expenses (including the fees and expenses of the Trustee)
connected therewith. In case any Security or coupon which has matured or is
about to mature shall become mutilated or be destroyed, lost or stolen, the
Company, instead of issuing a substitute Security or coupon, may pay or
authorize the payment of the same (without surrender thereof except in the case
of a mutilated Security or coupon) if the applicant for such payment shall
furnish to the Company and to the Trustee such security or indemnity as may be
required by them to hold each of them harmless and, in case of destruction, loss
or theft, evidence satisfactory to the Company and the Trustee of the
destruction, loss or theft of such Security or coupon and of the ownership of
such Security or coupon.

          (c)  Every substitute Security or coupon issued pursuant to the
provisions of this Section 2.07 by virtue of the fact that any Security or
coupon is destroyed, lost or stolen shall constitute an additional contractual
obligation of the Company, whether or not the destroyed, lost or stolen Security
or coupon shall be found at any time, and shall be entitled to all the benefits
of this Indenture equally and proportionately with any and all other Securities
or coupons of the relevant series duly issued under this Indenture.  All
Securities or coupons shall be held and owned by the holders upon the express
condition that the foregoing provisions are exclusive with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities or
coupons and shall preclude any and all other rights or remedies notwithstanding
any law or statute existing or hereafter enacted to the contrary with respect to
the replacement or payment of negotiable instruments or other securities without
their surrender.

          (d)  Notwithstanding the foregoing, the payment of principal of and
any premium and interest on Bearer Securities, except as otherwise provided in
Section 3.02, shall be payable only at an office or an agency located outside of
the United States, and, with respect to any coupons, interest represented
thereby shall be payable only upon presentation and surrender of such coupons.

          SECTION 2.08.  Temporary Securities.  (a) Pending the preparation
                         --------------------                                 
of definitive Securities of any series, the Company may execute and the Trustee
shall authenticate and deliver temporary Securities (printed or lithographed).
Temporary Securities shall be issuable in any authorized denomination, and
substantially in the form of the definitive Securities of such series (and of
like tenor and terms) in lieu of which they are issued in registered form or, if
authorized, in bearer form with one or more coupons 

                                      22
<PAGE>
 
or without coupons, but with such omissions, insertions and variations as may be
appropriate for temporary Securities, all as may be determined by the Company.
In the case of Securities of any series issuable as Bearer Securities, such
temporary Securities may be in global form, representing all or any part of the
Outstanding Securities of such series.

          (b)  Unless otherwise provided pursuant to Section 2.01:

               (i)  Except in the case of temporary Securities in global form,
     every such temporary Security shall be authenticated by the Trustee in
     substantially the same manner, and with the same effect, as the definitive
     Securities.  Without unreasonable delay the Company will execute and
     deliver to the Trustee definitive Securities of such series and thereupon
     any or all temporary Securities of such series (accompanied, if applicable,
     by all unmatured coupons and all unpaid matured coupons appertaining
     thereto) may be surrendered in exchange therefor at the principal office of
     the Trustee, and the Trustee shall authenticate and deliver in exchange for
     such temporary Securities an equal aggregate principal amount of definitive
     Securities of such series of authorized denominations.  Such exchange shall
     be made at the Company's expense and without any charge to the holder.
     Until so exchanged, the temporary Securities of any series in all respects
     shall be entitled to the same benefits under this Indenture as definitive
     Securities of such series authenticated and delivered under this Indenture.
     Notwithstanding the foregoing, no Bearer Security shall be delivered in
     exchange for a Registered Security, and a Bearer Security shall be
     delivered in exchange for a Bearer Security only in compliance with the
     conditions set forth in Section 2.06.

              (ii)  If Securities of any series are issued in temporary global
     form, any such temporary Global Security, unless otherwise provided
     pursuant to Section 2.01, shall be delivered to the Depositary for the
     benefit of Euro-clear and CEDEL S.A. for credit to the respective accounts
     of the beneficial owners of such Securities or to such other accounts as
     they may direct.

             (iii)  Any such temporary Global Security shall be exchangeable,
     on the terms and in the manner set forth therein, in whole or in part, for
     an equal aggregate principal amount of definitive Securities of the same
     series of authorized denominations and of like tenor 

                                      23
<PAGE>
 
     and terms as the portions of such temporary Global Security to be
     exchanged. Any definitive Bearer Security shall be delivered in exchange
     for a portion of a temporary Global Security only upon receipt by the
     Trustee from the Person entitled to receive such definitive Bearer Security
     of a Bearer Security Tax Certificate.

              (iv)  Until exchanged in full as hereinabove provided, the
     temporary Securities of any series shall be entitled in all respects to the
     same benefits under this Indenture as definitive Securities of the same
     series and of like tenor and terms authenticated and delivered hereunder,
     except that any interest payable with respect to a temporary Global
     Security will be paid as specified therein.

          SECTION 2.09.  Payment of Interest; Interest Rights.  Interest on
                         ------------------------------------                 
any Registered Security which is payable, and is punctually paid or duly
provided for, on any Interest Payment Date shall be paid to the Person in whose
name that Registered Security (or one or more Predecessor Securities) is
registered at the close of business on the Regular Record Date for such
interest.  In case a Bearer Security of any series is surrendered in exchange
for a Registered Security of such series after the close of business (at an
office or agency in a Place of Payment for such series) on any Regular Record
Date and before the opening of business (at such office or agency) on the next
succeeding Interest Payment Date, such Bearer Security shall be surrendered
without the coupon relating to such Interest Payment Date and interest will not
be payable on such Interest Payment Date in respect of the Registered Security
issued in exchange for such Bearer Security, but will be payable only to the
holder of such coupon when due in accordance with the provisions of this
Indenture.  Payment of interest on any Registered Security may be made as
provided in Section 3.02.  Except as otherwise provided in the terms of any
particular series pursuant to Section 2.01. interest will be calculated on the
basis of a year consisting of twelve 30-day months.

          Any interest on any Security that is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date ("Defaulted Interest")
forthwith shall cease to be payable to the holder on the relevant Regular Record
Date by virtue of having been such holder; and such Defaulted Interest may be
paid by the Company, at its election in each case, as provided in clause (i) or
(ii) below:

               (i)  The Company may elect to make payment of any Defaulted
     Interest to the Persons in whose names 

                                      24
<PAGE>
 
     such Securities (or their respective Predecessor Securities) are registered
     at the close of business on a Special Record Date for the payment of such
     Defaulted Interest, which shall be fixed in the following manner. The
     Company shall notify the Trustee in writing of the amount of Defaulted
     Interest proposed to be paid on each Security and the date of the proposed
     payment, and at the same time the Company shall deposit with the Trustee an
     amount of money equal to the aggregate amount proposed to be paid in
     respect of such Defaulted Interest or shall make arrangements satisfactory
     to the Trustee for such deposit prior to the date of the proposed payment,
     such money when deposited to be held in trust for the benefit of the
     Persons entitled to such Defaulted Interest as provided in this clause (i).
     Thereupon the Trustee shall fix a Special Record Date for the payment of
     such Defaulted Interest which shall be not more than 15 nor fewer than ten
     days prior to the date of the proposed payment and not fewer than ten days
     after the receipt by the Trustee of the notice of the proposed payment. The
     Trustee promptly shall notify the Company of such Special Record Date and,
     in the name and at the expense of the Company, shall cause notice of the
     proposed payment of such Defaulted Interest and the Special Record Date
     therefor to be mailed, first class, postage prepaid, to each holder at his
     address as it appears in the Security Register, not fewer than ten days
     prior to such Special Record Date. Notice of the proposed payment of such
     Defaulted Interest and the Special Record Date therefor having been given
     as aforesaid, such Defaulted Interest shall be paid to the Persons in whose
     names the Securities (or their respective Predecessor Securities) are
     registered on such Special Record Date and shall no longer be payable
     pursuant to the following clause (ii).

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

          Subject to the foregoing provisions of this Section 2.09, each
Security of any series delivered under this Indenture upon registration of
transfer of or in exchange for or in lieu of any other Security of such series

                                      25
<PAGE>
 
shall carry the rights to interest accrued and unpaid, and to accrue, that were
carried by such other Security.

          Subject to the limitations set forth in Section 3.02, the holder of
any coupon appertaining to a Bearer Security shall be entitled to receive the
interest payable on such coupon upon presentation and surrender of such coupon
on or after the Interest Payment Date of such coupon at an office or agency
maintained for such purpose pursuant to Section 3.02.

          SECTION 2.10.  Cancellation of Securities Paid, etc.  All Securities
                         -------------------------------------        
and coupons surrendered for the purpose of payment, exchange or registration of
transfer, if surrendered to the Company or any Paying Agent or any Security
registrar, shall be delivered to the Trustee and promptly canceled by the
Trustee or, if surrendered to the Trustee, promptly shall be canceled by it; and
no Securities or coupons shall be issued in lieu thereof except as expressly
permitted by any of the provisions of this Indenture. The Trustee may destroy
canceled Securities or coupons and will deliver a certificate of such
destruction to the Company.

                                 ARTICLE THREE
                                        
                      PARTICULAR COVENANTS OF THE COMPANY

          SECTION 3.01.  Payment of Principal and Interest.  The Company duly
                         ---------------------------------                     
and punctually will pay or cause to be paid the principal of and any premium and
interest on the Securities of each series at the places, at the respective times
and in the manner provided in this Indenture and in the Securities.  Any
interest due on Bearer Securities on or before Maturity shall be payable only
upon presentation and surrender of the several coupons for such interest
installments as are evidenced thereby as they severally mature.

          SECTION 3.02.  Offices for Notices and Payments, etc.  So long as any
                         --------------------------------------              
Securities of a series remain Outstanding, the Company will maintain in each
Place of Payment for such series of Securities an office or agency where the
Securities of that series (but, except as otherwise provided below, unless such
Place of Payment is located outside the United States, not Bearer Securities)
may be presented for payment, for registration of transfer and for exchange as
provided in this Indenture and where notices and demands to or upon the Company
in respect of the Securities or of this Indenture may be served. If Securities
of a series are issuable as Bearer Securities,

                                      26
<PAGE>
 
the Company will maintain, subject to any laws or regulations applicable
thereto, an office or agency in a Place of Payment for such series that is
located outside the United States where Securities of such series and the
related coupons may be presented for payment. The Company will give to the
Trustee prompt written notice of the location of each such office or agency and
of any change of location thereof. In case the Company shall fail to maintain
any such office or agency or shall fail to give such notice of the location or
of any change in the location thereof, presentations and demands may be made and
notices may be served at the principal office of the Trustee, and the Company
hereby initially appoints the Trustee its agent to receive all such
presentations and demands, except that Bearer Securities of that series and the
related coupons may be presented for payment at the place specified for that
purpose pursuant to Section 2.01(5). Unless otherwise provided pursuant to
Section 2.01, the Company hereby initially designates as the Place of Payment
for each series of Securities (other than Bearer Securities of that series and
the related coupons) the Borough of Manhattan, The City of New York, New York
and appoints the Trustee, at the principal office of the Trustee, as Paying
Agent in such city. Notwithstanding any other provisions to the contrary, the
Company at its option may make payment of principal and any premium and interest
                                          ---------     ------------------------
with respect to any Registered Security by check mailed to the Person entitled
thereto, as such address appears on the Security Register, except that a holder
of $10,000,000 or more in aggregate principal amount of Securities of such
series and of like tenor and terms will be entitled to receive payments by wire
transfer of immediately available funds if appropriate wire transfer
instructions shall have been received in writing by the Trustee not later than
ten Business Days prior to the applicable payment date.

          No payment of principal of or any premium or interest on Bearer
Securities shall be made at any office or agency of the Company 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, that payment of principal of and any premium and interest on any Bearer
Security may be made at an office or agency of, and designated by, the Company
located in the United States if (but only if) payment of the full amount of such
principal, premium or interest at all offices outside the United States
maintained for the purpose by the Company in accordance with this Indenture is
illegal or effectively precluded by exchange controls or other similar
restrictions and the Trustee receives an Opinion of Counsel that such payment
within the United States is legal.  Unless otherwise provided as contemplated by
Section 2.01 

                                      27
<PAGE>
 
with respect to any series of Securities, at the option of the holder of any
Bearer Security or related coupon payment may be made by mailing a check to an
address outside the United States or by transfer to an account maintained by the
payee with a bank located outside the United States.

          The Company also from time to time may designate one or more offices
or agencies (in or outside of such Place of Payment) where the Securities of one
or more series and any appurtenant coupons (subject to the preceding paragraph)
may be presented or surrendered for any and all such purposes, and from time to
time may rescind such designations.  The Company will give prompt written notice
to the Trustee of any such designation and any change in the location of any
such office or agency.

          SECTION 3.03.  Provisions as to Paying Agent.  (a) The Company, with
                         -----------------------------                      
respect to the Securities of each series, prior to each due date of principal of
or any premium or interest on such Securities, will deposit with the Paying
Agent for such Securities a sum sufficient to pay the principal, premium or
interest so becoming due, such sum to be held in trust for the benefit of the
persons entitled to such principal, premium or interest. If the Company shall
appoint a Paying Agent other than the Trustee with respect to the Securities of
any series, the Company will notify the Trustee of its making, or failure to
make, any such payment; and the Company also shall cause any such Paying Agent
to execute and deliver to the Trustee an instrument in which such agent shall
agree with the Trustee, subject to the provisions of this Section 3.03, as
follows:

               (1)  that it will hold all sums held by it as such agent for the
     payment of the principal of or any premium or interest on such Securities
     (whether such sums have been paid to it by the Company or by any other
     obligor on such Securities) in trust for the benefit of the Persons
     entitled thereto;

               (2)  that it will give the Trustee notice of any failure by the
     Company (or by any other obligor on such Securities) to make any payment of
     the principal of or any premium or interest on such Securities when the
     same shall be due and payable; and

               (3)  that it forthwith will pay to the Trustee, at any time
     during the continuance of an Event of Default, upon the written request of
     the Trustee, all sums so held by it as such agent.

          (b)  If the Company shall act as its own Paying Agent with respect to
the Securities of any series, on or 

                                      28
<PAGE>
 
before each due date of the principal of or any premium or interest on the
Securities of such series, it will set aside, segregate and hold in trust for
the benefit of the Persons entitled thereto a sum sufficient to pay such
principal, premium or interest so becoming due and will notify the Trustee of
any failure to take such action and of any failure by the Company (or by any
other obligor under such Securities) to make any payment of the principal of or
any premium or interest on such Securities when the same shall become due and
payable.

          Subsidiary.

          Notwithstanding the foregoing, any such sale, assignment, transfer or
other disposition of securities, any such merger or consolidation or any such
lease, sale or transfer of properties and assets shall not be prohibited if
required (i) by any law or any rule, regulation or order of any governmental

shares of, Voting Stock subject thereto to the secured party, the Principal
Constituent Bank would not be a Controlled Subsidiary.

<PAGE>
 
     covenant or agreement a default in the performance of which or the breach
     of which specifically is provided for elsewhere in this Section 4.01 or
     which expressly has been included in this Indenture solely for the benefit
     of one or more series of Securities other than such series), and
     continuance of such failure for a period of 90 days after the date on which
     written notice of such failure, requiring the Company to remedy the same,

     the appointment of or taking possession by a receiver, liquidator,
     assignee, trustee, custodian, sequestrator (or similar official) of the
     Company or a Principal Constituent Bank or for substantially all of its
     property, or shall make any general assignment for the benefit of
     creditors, or shall fail generally to pay its debts as they become due or
     shall take any corporate action in furtherance of any of the foregoing.

          If an Event of Default with respect to the Securities of any series at
the time Outstanding occurs and is continuing, then and in each such case,
unless the principal of all the Securities of such series already shall have
become due and payable, either the Trustee or the holders of not less than 25%
in aggregate principal amount of the Securities of such series then Outstanding,
by notice in writing to the Company (and to the Trustee if given by
Securityholders), may declare the principal amount of all 

                                      33
<PAGE>
 
the Securities of that series to be due and payable immediately, and upon any
such declaration the same shall become and shall be immediately due and payable.
This provision, however, is subject to the condition that, at any time after
such a declaration of acceleration, and before any judgment or decree for the
payment of the money due shall have been obtained or entered as hereinafter
provided, the holders of a majority in aggregate principal amount of the
Securities of such series then Outstanding, by written notice to the Company and
to the Trustee, may waive all defaults and rescind and annul such declaration
and its consequences, if:

               (1)  the Company shall pay or shall deposit with the Trustee a
     sum sufficient to pay:

                    (A)  all matured installments of interest on all the
          Securities of that series and the principal of and any premium on any
          and all Securities of that series that shall have become due otherwise
          than by acceleration (with interest on overdue installments of
          interest (to the extent that payment of such interest is enforceable
          under applicable law) and on such principal and premium at the rate
          borne by the Securities of that series, to the date of such payment or
          deposit); and

                    (B)  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

               (2)  any and all defaults with respect to Securities of that
     series under this Indenture, other than the nonpayment of principal of and
     any premium and accrued interest on Securities that shall have become due
     by acceleration, shall have been cured or waived as provided in Section
     4.07.

No such waiver or rescission and annulment shall extend or shall affect any
subsequent default or shall impair any right consequent thereon.

          In case the Trustee or any Securityholder shall have proceeded to
enforce any right under this Indenture and such proceedings shall have been
discontinued or abandoned because of such rescission or annulment or for any
other reason or shall have been determined adversely to the Trustee or any
Securityholder, then and in every such case the Company, the Trustee and such
Securityholders, subject to any determination in such proceeding, shall be
restored 

                                      34
<PAGE>
 
respectively to their several positions and rights under this Indenture, and all
rights, remedies and powers of the Company, the Trustee and such Securityholders
shall continue as though no such proceeding had been taken.

          SECTION 4.02.  Payment of Securities on Default; Suit Therefor.
                         -----------------------------------------------     
(a) In case default shall be made in the payment of (i) any installment of
interest upon any of the Securities as and when the same shall become due and
payable, and such default shall have continued for a period of 30 days, or (ii)
the principal of or any premium on any of the Securities as and when the same
shall have become due and payable whether at Maturity of the Securities, by
declaration or otherwise, then, upon demand of the Trustee, the Company will pay
to the Trustee, for the benefit of the holders of the Securities, the whole
amount that then shall have become due and payable on all such Securities for
principal, premium or interest, or any combination thereof, as the case may be,
with interest upon the overdue principal and premium and (to the extent that
payment of such interest is enforceable under applicable law) upon the overdue
installments of interest, at the rate borne by the Securities; and, in addition,
such further amount as shall be sufficient to cover the costs and expenses of
collection, including reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents, attorneys and counsel.

          (b)  In case the Company shall fail forthwith to pay such amounts upon
such demand, the Trustee, in its own name and as trustee of an express trust,
shall be entitled and empowered to institute any actions or proceedings at law
or in equity for the collection of the sums so due and unpaid, and may prosecute
any such action or proceeding to judgment or final decree, and may enforce any
such judgment or final decree against the Company or any other obligor on the
Securities and coupons and collect in the manner provided by law out of the
property of the Company or any other obligor on the Securities and coupons,
wherever situated, the money adjudged or decreed to be payable.

          (c)  In case there shall be pending proceedings for the bankruptcy or
for the reorganization of the Company or any other obligor on the Securities and
coupons under Title 11 of the United States Code or any other applicable law, or
in case a receiver or trustee shall have been appointed for the property of the
Company or such other obligor, or in the case of any other similar judicial
proceedings relative to the Company or other obligor on the Securities and
coupons, or to the creditors or property of the Company or such other obligor,
the Trustee, irrespective of whether the principal of the Securities shall then
be due 

                                      35
<PAGE>
 
and payable as expressed in the Securities or by declaration or otherwise and
irrespective of whether the Trustee shall have made any demand pursuant to the
provisions of this Section 4.02, shall be entitled and empowered, by
intervention in such proceedings or otherwise, to file and prove a claim or
claims for the whole amount of principal and any premium and interest owing and
unpaid in respect of the Securities, and, in case of any judicial proceedings,
(i) to file such proofs of claim and 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 and counsel) and of the Securityholders allowed in such
judicial proceedings relative to the Company or any other obligor on the
Securities and coupons, its or their creditors, or its or their property, and
(ii) to collect and receive any money or other property payable or deliverable
on any such claims, and to distribute the same after the deduction of its
charges and expenses; and any receiver, assignee or trustee in bankruptcy or
reorganization is hereby authorized by each of the Securityholders 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 Securityholders, to pay to the Trustee
any amount due it for reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and its counsel and any other amounts due
the Trustee under Section 5.06. To the extent that such payment of reasonable
compensation, expenses and counsel fees out of the trust estate in any such
proceedings shall be denied for any reason, payment of the same shall be secured
by a lien on, and shall be paid out of, any and all distributions, dividends,
money, securities and other property which the holders of the Securities and
coupons may be entitled to receive in such proceedings, whether in liquidation
or under any plan of reorganization or arrangement or otherwise.

          (d)  Nothing contained in this Section 4.02 shall be deemed to
authorize the Trustee to authorize or consent to or adopt on behalf of any
Securityholder any plan of reorganization or arrangement affecting the
Securities or related coupons or the rights of any Securityholder, or to
authorize the Trustee to vote in respect of the claim of any Securityholder in
any such proceeding.

          (e)  All rights of action and of asserting claims under this
Indenture, or under any of the Securities or related coupons, may be enforced by
the Trustee without the possession of any of the Securities or coupons, or the
production thereof in any trial or other proceeding relative thereto, and any
such suit or proceeding instituted by the 

                                      36
<PAGE>
 
Trustee shall be brought in its own name as trustee of an express trust, and any
recovery of 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 the holders of the Securities
and related coupons.

          SECTION 4.03.  Application of Money Collected by Trustee.  Any money
                         -----------------------------------------              
collected by the Trustee with respect to any series of Securities or related
coupons pursuant to Section 4.02 shall be applied in the order following, at the
date or dates fixed by the Trustee for the distribution of such money, upon
presentation of the several Securities of such series or coupons, or both, as
the case may be, and stamping thereon the payment, if only partially paid, and
upon surrender thereof if fully paid:

          FIRST:  To the payment of all amounts then due the Trustee under
     Section 5.06;

          SECOND:  In case the principal of the Outstanding Securities of that
     series shall not have become due and be unpaid, to the payment of interest
     on the Securities of that series in the order of the Maturity of the
     installments of such interest, with interest (to the extent enforceable
     under applicable law) upon the overdue installments of interest at the rate
     borne by the Securities of that series, such payments to be made ratably to
     the persons entitled thereto; and

          THIRD:  In case the principal of the Outstanding Securities of that
     series shall have become due, by declaration or otherwise, to the payment
     of the whole amount then owing and unpaid upon the Securities of that
     series for principal and any premium and interest, with interest on the
     overdue principal and any premium and (to the extent enforceable under
     applicable law) upon overdue installments of interest at the rate borne by
     the Securities of that series; and in case such money shall be insufficient
     to pay in full the whole amounts so due and unpaid upon the Securities of
     that series, then to the payment of such principal and any premium and
     interest without preference or priority of principal over interest, or of
     interest over principal, or of any premium over principal or interest, or
     of principal or interest over any premium or of any installment of interest
     over any other installment of interest, or of any Security of that series
     over any other Security of that series, or of any coupon related to a
     Security of a series over any other coupon related to a Security of the
     same series, ratably to the 

                                      37
<PAGE>
 
     aggregate of such principal and any premium and accrued and unpaid
     interest.

          SECTION 4.04.  Proceedings by Securityholders.  No holder of any
                         ------------------------------                     
Security of any series or any related coupon shall have any right to institute
any suit, action or proceeding in equity or at law upon or under or with respect
to this Indenture or for the appointment of a receiver or trustee, or for any
other remedy under this Indenture, unless such holder previously shall have
given to the Trustee written notice of default and of the continuance thereof,
as provided in Section 4.01, and unless also (i) the holders of not less than
25% in aggregate principal amount of the Securities of that series then
Outstanding shall have made written request upon the Trustee to institute such
action, suit or proceeding in its own name as Trustee under this Indenture and
shall have offered to the Trustee such reasonable indemnity as the Trustee may
require against the costs, expenses and liabilities to be incurred in compliance
with such request, (ii) the Trustee for 60 days after its receipt of such
notice, request and offer of indemnity, shall have neglected or refused to
institute any such action, suit or proceeding and (iii) 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 that series; it being understood and intended, and
being expressly covenanted by each Person who acquires and holds a Security or
related coupon with every other such Person, that no one or more holders of
Securities shall have any right in any manner whatever by virtue of or by
availing of any provision of this Indenture to affect, disturb or prejudice the
rights of any other holder of such Securities or coupons, or to obtain or seek
to obtain priority over or preference to any other such holder, or to enforce
any right under this Indenture, except in the manner provided in this Section
4.04 and for the equal, ratable and common benefit of all holders of Securities
and coupons.

          Notwithstanding any other provision of this Indenture, however, the
right of any holder of any Security to receive payment of the principal of and
any premium and interest on such Security on or after the respective Stated
Maturities, or to institute suit for the enforcement of any such payment on or
after such respective dates against the Company, shall not be impaired or
affected without the consent of such holder.

          SECTION 4.05.  Proceedings by Trustee.  In case of an Event of
                         ----------------------                           
Default under this Indenture, the Trustee in its discretion may proceed to
protect and enforce its rights and the rights of the Securityholders by such
appropriate 

                                      38
<PAGE>
 
judicial proceedings as the Trustee shall deem most effectual to protect and
enforce any such rights, either by suit in equity or by action at law or by
proceeding in bankruptcy or otherwise, whether for the specific enforcement of
any covenant or agreement contained in this Indenture or in aid of the exercise
of any power granted in this Indenture, or to enforce any other proper remedy or
legal or equitable right vested in the Trustee by this Indenture or by law.

          SECTION 4.06.  Remedies Cumulative and Continuing; Delay or Omission
                         -----------------------------------------------------
Not Waiver.  All rights, powers and remedies conferred upon or reserved to the
- ----------                                                                      
Trustee or to the Securityholders, to the extent permitted by law, shall be
deemed cumulative and not exclusive of any thereof or of any other rights,
powers and remedies available to the Trustee or the holders of the Securities
and related coupons, now or hereafter existing, by judicial proceedings or
otherwise, to enforce the performance or observance of the covenants and
agreements contained in this Indenture; and no delay or omission of the Trustee
or of any holder of any of the Securities or related coupons to exercise any
such right, power or remedy shall impair any such right, power or remedy, or
shall be construed to be a waiver of any default or an acquiescence in such
default; and, subject to the provisions of Section 4.04, every power and remedy
conferred upon or reserved to the Trustee or to the Securityholders may be
exercised from time to time, and as often as shall be deemed expedient, by the
Trustee or by the Securityholders.  The assertion of any right, power or remedy
shall not prevent the concurrent assertion of any other right, power or remedy.

          SECTION 4.07.  Direction of Proceedings and Waiver of Defaults by
                         --------------------------------------------------
Majority of Securityholders.    (a) The holders of a majority in aggregate
- ---------------------------                                               
principal amount of the Securities of all series affected (voting as one class)
at the time Outstanding determined in accordance with Section 6.04 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; provided, however, that (i) such direction may not be in
conflict with law or this Indenture or expose the Trustee to personal liability
or be unduly prejudicial to the holders of the Securities and related coupons
not joining in the direction, and (ii) the Trustee may take any other action
deemed proper by the Trustee that is not inconsistent with this Indenture and
such direction.

          (b)  Prior to any declaration that the principal of the Outstanding
Securities of any series is due and payable, the holders of a majority in
aggregate principal 

                                      39

amount of the Securities of that series at the time Outstanding on behalf of the
holders of all of the Securities of that series may waive any past default or
Event of Default under this Indenture and its consequences except a default
under a covenant in this Indenture that, pursuant to Section 8.02, cannot be
modified without the consent of each holder of a Security of the series affected
thereby. Upon any such waiver, the Company, the Trustee and the holders of the
Securities of that series and the related coupons shall be restored to their
former positions and rights under this Indenture, respectively; but no such
waiver shall extend to any subsequent or other default or Event of Default or
impair any right consequent thereon. Whenever any default or Event of Default
under this Indenture shall have been waived as permitted by this Section 4.07,
such default or Event of Default, for all purposes of the Securities, the
related coupons and this Indenture, shall be deemed to have been cured and to be
not continuing.

          SECTION 4.08.  Notice of Defaults.  The Trustee, within 90 days
                         ------------------                                
after the occurrence of a default with respect to Securities of any series,
shall mail to all Securityholders of that series, at their addresses shown on
the Security Register, notice of all such defaults known to the Trustee, unless
such defaults shall have been cured or waived before the giving of such notice
(the term "default" for the purpose of this Section 4.08 being hereby defined to
mean any event which constitutes or after notice or lapse of time or both would
constitute an Event of Default); and provided that, except in the case of
default in the payment of the principal of or any premium or interest on any of
the Securities of that series or in the making of any sinking fund payment or
analogous obligation with respect to Securities of that 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 or
Responsible Officers of the Trustee in good faith determines that the
withholding of such notice is in the interest of the Securityholders of that
series.

          SECTION 4.09.  Undertaking to Pay Costs.  All parties to this
                         ------------------------                        
Indenture agree, and each holder of any Security or coupon by his acceptance
thereof shall be deemed to have agreed, that any court in its discretion may
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 an undertaking
to pay the costs of such suit and that such court in its discretion may assess
reasonable costs, including reasonable attorneys' fees, against any party

                                      40
<PAGE>
 
litigant; provided, however, that the provisions of this Section 4.09 shall not
apply to any suit instituted by the Trustee, to any suit instituted by any
Securityholder, or group of Securityholders, holding in the aggregate more than
10% in principal amount of the Outstanding Securities of that series, or to any
suit instituted by any Securityholder for the enforcement of the payment of the
principal of or any premium or interest on any Security on or after the
respective Stated Maturities (or, in the case of redemption or repayment, on or
after the redemption date or repayment date).

          SECTION 5.01.  Duties and Responsibilities of Trustee.  In case an
                         --------------------------------------               
Event of Default has occurred (which has not been cured or waived) the Trustee
shall exercise such of the rights and powers vested in it by this Indenture, and
use the same degree of care and skill in their exercise, as a prudent man would
exercise or use under the circumstances in the conduct of his own affairs.

          No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, its own willful misconduct or any action or failure to act taken or
omitted by it in bad faith, except that:

          (a)  except during the continuance of an Event of Default:

                    (1)  the duties and obligations of the Trustee shall be
          determined solely by the express provisions of this Indenture, and the
          Trustee shall not be liable except for the performance of such duties
          and obligations as are specifically set forth in this Indenture, and
          no implied covenants or obligations shall be read into this Indenture
          against the Trustee; and

                    (2)  in the absence of bad faith on the part of the Trustee,
          the Trustee conclusively may rely, as to the truth of the statements
          and the correctness of the opinions expressed therein, upon any
          certificates or opinions furnished to the Trustee and conforming to
          the requirements of this Indenture; but, in the case of any such
          certificates or opinions that by any provisions of this Indenture
          specifically are required to be 

                                      41
<PAGE>
 
          furnished to the Trustee, the Trustee shall be under a duty to examine
          the same to determine whether or not they conform to the requirements
          of this Indenture;

          (b)  the Trustee shall not be liable for any error of judgment made in
     good faith by a Responsible Officer or Officers of the Trustee, unless it
     shall be proved that the Trustee was negligent in ascertaining the
     pertinent facts; and

          (c)  the Trustee shall not be liable with respect to any action taken
     or omitted to be taken by it in good faith in accordance with the direction
     of the holders of not less than a majority in principal amount of the
     Securities of any series at the time Outstanding (determined as provided in
     Section 6.04) relating to the time, method and place of conducting any
     proceeding for any remedy available to the Trustee, or exercising any trust
     or power conferred upon the Trustee, under this Indenture.

          None of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of
its rights or powers, if it shall have reasonable grounds for believing that the
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

          Whether or not expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of this Section
5.01.

          The provisions of this Section 5.01 are in furtherance of and subject
to Sections 315 and 316 of the Trust Indenture Act.

          SECTION 5.02.  Reliance on Documents, Opinions, etc.   Subject to the
                         -------------------------------------                  
applicable provisions of the Trust Indenture Act and in furtherance thereof and
subject to the provisions of Section 5.01:

          (a)  the Trustee may rely and shall be protected in acting upon any
     resolution, certificate, statement, instrument, opinion, report, notice,
     request, consent, order, bond, debenture or other paper or document
     believed by it to be genuine and to have been signed or presented by the
     proper party or parties;

                                      42
<PAGE>
 
          (b)  any request, direction, order or demand of the Company mentioned
     herein shall be sufficiently evidenced by an Officers' Certificate (unless
     other evidence in respect thereof be herein specifically prescribed); and
     any resolution of the Board of Directors may be evidenced to the Trustee by
     a copy thereof certified by the Secretary or an Assistant Secretary of the
     Company;

          (c)  the Trustee may consult with counsel and any Opinion of Counsel
     shall be full and complete authorization and protection in respect of any
     action taken or omitted by it under this Indenture in good faith and in
     accordance with such Opinion of Counsel;

          (d)  the Trustee shall be under no obligation to exercise any of the
     rights or powers vested in it by this Indenture at the request, order or
     direction of any of the Securityholders, pursuant to the provisions of this
     Indenture, unless such Securityholders shall have offered to the Trustee
     reasonable security or indemnity against the costs, expenses and
     liabilities that may be incurred therein or thereby;

          (e)  the Trustee shall not be liable for any action taken or omitted
     by it in good faith and believed by it to be authorized or within the
     discretion or rights or powers conferred upon it by this Indenture;

          (f)  the Trustee shall not be bound to make any investigation into the
     facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, report, notice, request, consent, order, approval,
     bond, debenture, coupon or other paper or document, but the Trustee, in its
     discretion, may make such further inquiry or investigation into such facts
     or matters as it may see fit, and, if the Trustee shall determine to make
     such further inquiry or investigation, it shall be entitled to examine the
     books and records of the Company to the extent reasonably necessary to
     verify such facts or matters; and

          (g)  the Trustee may execute any of the trusts or powers under this
     Indenture or perform any duties under this Indenture either directly or by
     or through agents or attorneys and the Trustee shall not be responsible for
     any misconduct or negligence on the part of any agent or attorney appointed
     by it with due care under this Indenture.

          SECTION 5.03.  No Responsibility for Recitals, etc.  The recitals
                         ------------------------------------                
contained in this Indenture and in the Securities (except in the Trustee's
certificate of authentication) and in any coupons shall be taken as the
statements of the Company, and the Trustee assumes no responsibility for the
correctness of the same.  The Trustee makes no representations as to the
validity or sufficiency of this Indenture or of the Securities or the coupons.
The Trustee shall not be accountable for the use or application by the Company
of any Securities or the proceeds of any Securities authenticated and delivered
by the Trustee.

          SECTION 5.04.  Trustee, Paying Agents or Registrar May Own Securities.
                         -------------------------------------------------------
Subject to the applicable provisions of the Trust Indenture Act, the Trustee or
any Paying Agent or Security registrar, in its individual or any other capacity,
may become the owner or pledgee of Securities with the same rights it would have
if it were not Trustee, Paying Agent or Security registrar.

          SECTION 5.05.  Money to Be Held in Trust.  Subject to the provisions
                         -------------------------                              
of Section 13.03 and Section 13.04, all money received by the Trustee, until
used or applied as herein provided, shall be held in trust for the purposes for
which it was received. Money held by the Trustee need not be segregated from
other funds except as provided by law. The Trustee shall be under no liability
for interest on any money received by it under this Indenture, except as the
Company and the Trustee otherwise may agree.

          SECTION 5.06.  Compensation and Expenses of Trustee.  The Company will
                         ------------------------------------                
pay to the Trustee from time to time, and the Trustee shall be entitled to,
reasonable compensation for all services rendered by it under this Indenture
(which shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust), and the Company will pay or
reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
any of the provisions of this Indenture (including the reasonable compensation

not regularly in its employ) except any such expense, disbursement or advance as
may be attributable to its negligence, bad faith or willful misconduct. The
Company also covenants to indemnify the Trustee for, and to hold it harmless
against, any loss, liability or expense incurred without negligence, bad faith
or willful misconduct on the part of the Trustee and arising out of or in
connection with the acceptance or administration of this trust, including the
reasonable costs and expenses of defending itself against any claim of liability
in connection with the 

                                      44
<PAGE>
 
exercise or performance of any of its powers under this Indenture. The
obligations of the Company under this Section 5.06 shall constitute additional
indebtedness under this Indenture.

          SECTION 5.07.  Officers' Certificate as Evidence.  Subject to the
                         ---------------------------------                   
provisions of Section 5.01, whenever in the administration of the provisions of
this Indenture the Trustee shall deem it necessary or desirable that a matter be
proved or established prior to taking or omitting any action under this
Indenture, such matter (unless other evidence in respect thereof be herein
specifically prescribed), in the absence of negligence, bad faith or willful
misconduct on the part of the Trustee, may be deemed to be conclusively proved
and established by an Officers' Certificate delivered to the Trustee, and such
Officers' Certificate, in the absence of negligence, bad faith or willful
misconduct on the part of the Trustee, shall be full warrant to the Trustee for
any action taken or omitted by it under the provisions of this Indenture upon
the faith of such Officers' Certificate.

          SECTION 5.08.  Eligibility of Trustee.  The Trustee under this
                         ----------------------                           
Indenture shall at all times be a corporation organized and doing business under
the laws of the United States or any State thereof or of the District of
Columbia (or a corporation or other person permitted to act as Trustee by the
Commission) authorized under such laws to exercise corporate trust powers,
having a combined capital and surplus of at least $50,000,000 and subject to
supervision or examination by Federal, State or District of Columbia authority.
If such corporation publishes reports of condition at least annually, pursuant
to law or to the requirements of the aforesaid supervising or examining
authority, then for the purposes of this Section 5.08 the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published.  In
case at any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section 5.08, the Trustee shall resign immediately in the
manner and with the effect specified in Section 5.09.  Neither the Company nor
any person directly or indirectly controlling, controlled by, or under common
control with the Company shall serve as Trustee under this Indenture.

          SECTION 5.09.  Resignation or Removal of Trustee.  (a) The Trustee
                         ---------------------------------                    
may resign at any time  by giving written notice of such resignation to the
Company, by mailing notice of such resignation to the holders of Registered
Securities at their addresses as they shall appear on the Security Register and,
if any Bearer Securities are Outstanding, by 

                                      45
<PAGE>
 
publishing notice of such resignation in a newspaper of general circulation, in
each place of payment for such Bearer Securities, customarily published at least
once a day for at least five days in each calendar week.

          (b)  In case at any time any of the following shall occur:

               (1)  the Trustee shall fail to comply with the provisions of
     Section 310(b) of the Trust Indenture Act after written request therefor by
     the Company or by any Securityholder who has been a bona fide holder of a
     Security or Securities for at least six months, or

               (2)  the Trustee shall cease to be eligible in accordance with
     the provisions of Section 5.08 and shall fail to resign after written
     request therefor by the Company or by any such Securityholder, or

               (3)  the Trustee shall become incapable of acting, or shall be
     adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its
     property shall be appointed or a 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, the Company may remove the Trustee by written
instrument, executed by Company Order authorized by the Board of Directors, one
copy of which instrument shall be delivered to the Trustee so removed and one
copy to the successor Trustee (with written notice of such removal mailed to the
holders of Registered Securities at their address as they shall appear on the
Security Register, and, if any Bearer Securities are Outstanding, by publishing
notice of such resignation in a newspaper of general circulation, in each place
of payment for such Bearer Securities, customarily published at least once a day
for at least five days in each calendar week), or, subject to the provisions of
Section 4.09, any Securityholder who has been a bona fide holder of a Security
or Securities for at least six months, on behalf of himself and all others
similarly situated, may petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee.

          (c)  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, the
Company promptly shall appoint a successor Trustee by a Company Order authorized
by the Board of Directors, one copy of which instrument shall be delivered to
the retiring Trustee and 

                                      46
<PAGE>
 
one copy to the successor Trustee. If, within one year after such resignation,
removal or incapability or the occurrence of such vacancy, a successor Trustee
shall be appointed by the holders of a majority in principal amount of the
Securities (voting as a single class) at the time Outstanding by instrument or
instruments delivered to the Company and the retiring Trustee, the successor
Trustee so appointed, forthwith upon its acceptance of such appointment, shall
become the successor Trustee and supersede the successor Trustee appointed by
the Company. If no successor Trustee shall have been so appointed by the Company
or the Securityholders and accepted appointment in the manner provided in
Section 5.10 within 60 days after notice of the resignation or removal of the
Trustee is mailed to the Securityholders, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee, or
any Securityholder who has been a bona fide holder of a Security or Securities
for at least six months, subject to the provisions of Section 4.09, on behalf of
himself and all others similarly situated, may petition any court of competent
jurisdiction for the appointment of a successor Trustee.

          (d)  The holders of a majority in aggregate principal amount of the
Securities (voting as a single class) at the time Outstanding at any time, upon
notice to the Trustee, may remove the Trustee.

          (e)  Any removal of the Trustee and appointment of a successor Trustee
pursuant to any of the provisions of this Section 5.09 shall become effective
upon acceptance of appointment by the successor Trustee as provided in Section
5.10.  Any resignation of the Trustee shall become effective only upon the
appointment of a successor Trustee and upon the acceptance of appointment by the
successor Trustee as provided in Section 5.10.

          SECTION 5.10.  Acceptance by Successor Trustee.  Any successor Trustee
                         -------------------------------                  
appointed as provided in Section 5.09 shall execute, acknowledge and deliver to
the Company and to its predecessor Trustee an instrument accepting such
appointment under this Indenture, and thereupon the resignation or removal of
the predecessor Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, duties and obligations of its predecessor under this Indenture,
with like effect as if originally named as Trustee in this Indenture; but,
nevertheless, on the written request of the Company or of the successor Trustee,
the Trustee ceasing to act, upon payment of any amounts then due it pursuant to
the provisions of Section 5.06, shall execute and deliver an 

                                      47
<PAGE>
 
instrument transferring to such successor Trustee all the rights and powers of
the Trustee so ceasing to act and shall transfer, assign and deliver to such
successor all property and money held by such predecessor Trustee under this
Indenture. Upon request of any such successor Trustee, the Company shall execute
any and all instruments in writing for more fully and certainly vesting in and
confirming to such successor Trustee all such rights and powers. Any Trustee
ceasing to act, nevertheless shall retain a lien upon all property or funds held
or collected by such Trustee to secure any amounts then due it pursuant to the
provisions of Section 5.06.

          No successor Trustee shall accept appointment as provided in this
Section 5.10 unless at the time of such acceptance such successor Trustee shall
be qualified under the provisions of Section 310(b) of the Trust Indenture Act
and eligible under the provisions of Section 5.08.

          Upon acceptance of appointment by a successor Trustee as provided in
this Section 5.10, the Company shall mail notice of the succession of such
Trustee under this Indenture to the holders of Registered Securities at their
addresses as they shall appear on the Security Register, and, if any Bearer
Securities are Outstanding, by publishing notice of such resignation in a
newspaper of general circulation, in each place of payment for such Bearer
Securities, customarily published at least once a day for at least five days in
each calendar week.  If the Company fails to mail such notice within ten days
after acceptance of appointment by the successor Trustee, the successor Trustee
shall cause such notice to be mailed and, if necessary, published at the expense
of the Company.

          SECTION 5.11.  Succession by Merger, etc.  Any corporation into which 
                         --------------------------                        
the Trustee may be merged or converted or with which it may be consolidated, or
any corporation resulting from any merger, conversion or consolidation to which
the Trustee shall be a party, or any corporation succeeding to all or
substantially all the corporate trust business of the Trustee, shall be the
successor Trustee under this Indenture without the execution or filing of any
paper or any further act on the part of any of the parties to this Indenture
provided such corporation shall be qualified under the provisions of Section
310(b) of the Trust Indenture Act and eligible under the provisions of Section
5.08.

          In case at the time such successor Trustee shall succeed to the trusts
created by this Indenture any of the Securities shall have been authenticated
but not delivered, any such successor Trustee may adopt the certificate of

                                      48
<PAGE>

authentication of any predecessor Trustee, and deliver such Securities so 
authenticated; and in case at that time any of the Securities shall not have
been authenticated, any successor Trustee may authenticate such Securities
either in the name of any predecessor Trustee under this Indenture or in the
name of the successor Trustee; and in all such cases such certificates shall
have the full force which it is anywhere in the Securities or in this Indenture
provided that the certificate of the Trustee shall have; provided, however, that
the right to adopt the certificate of authentication of any predecessor Trustee
or authenticate Securities in the name of any predecessor Trustee shall apply
only to its successor or successors by merger, conversion or consolidation.

                        CONCERNING THE SECURITYHOLDERS

          SECTION 6.01.  Action by Securityholders.  Whenever in this Indenture 
                         -------------------------                     
it is provided that the holders of a specified percentage in aggregate principal
amount of the Securities of any or all series may take any action (including the
making of any demand or request, the giving of any notice, consent or waiver or
the taking of any other action), the fact that at the time of taking any such
action the holders of such specified percentage have joined in such action may
be evidenced (i) by any instrument or any number of instruments of similar tenor
executed by Securityholders in person or by agent or proxy appointed in writing,
(ii) by the record of the holders of Securities voting in favor of such action
at any meeting of Securityholders duly called and held in accordance with the
provisions of this Article Six or (iii) by a combination of such instrument or
instruments and any such record of such a meeting of Securityholders. The
Company may set a record date for purposes of determining the identity of
holders entitled to vote or consent to any action by vote or consent authorized
or permitted under this Indenture, which record date shall be the later of ten
days prior to the first solicitation of such consent or the date of the most
recent list of holders furnished to the Trustee pursuant to the provisions of
Section 312(a) of the Trust Indenture Act prior to such solicitation. If a
record date is fixed, those persons who were holders of Securities at such
record date (or their duly designated proxies), and only those persons, shall be
entitled to take such action by vote or consents or to revoke any vote or
consent previously given, whether or not such persons continue to be holders
after such record date. No such vote or consent shall be valid or effective if
such 

                                      49
<PAGE>
 
vote occurs or such consent is obtained more than 120 days after such record

     transfer or which leases the properties and assets of the Company
     substantially as an entirety shall be a corporation organized and existing
     under the laws of the United States of America, any State thereof or the
     District of Columbia and expressly shall assume, by a supplemental
     indenture executed and delivered to the Trustee in form satisfactory to the
     Trustee, the due and punctual payment of the principal of and any premium
     and interest on the Securities, according to their terms, and the
     performance of every covenant of this Indenture and in such series on the
     part of the Company to be performed or observed;

     conditions precedent provided for in this Indenture relating to such
     transaction have been complied with.

          SECTION 9.02.  Successor Corporation Substituted.  Upon any
                         ---------------------------------             
consolidation by the Company with or merger by the Company into any other
corporation or any conveyance, transfer or lease of the properties and assets of
the Company substantially as an entirety in accordance with Section 9.01, the
successor corporation formed by such consolidation or into which the Company is

been named as the Company in this Indenture, and thereafter, except in the case
of a lease, the predecessor corporation shall be relieved of all obligations and
covenants under this Indenture and the Securities of each series and any related
coupons.

corporation thereafter shall cause to be signed and delivered to the Trustee on
its behalf for that purpose.  All the Securities so issued shall have in all
respects the same legal rank and benefit under this Indenture as the Securities
theretofore or thereafter issued in accordance with the terms of this Indenture
as though all such Securities had been issued at the date of the execution of
this Indenture.

                          ------------------------                             
that are redeemable before their Stated Maturity shall be redeemable only in
accordance with their terms and (except as otherwise specified as contemplated
by Section 2.01 for Securities of any series) in accordance with this Article
Ten.

          SECTION 10.02.  Election to Redeem; Notice to Trustee.  The election 
                          -------------------------------------                 
of the Company to redeem any Securities shall be evidenced by a Company Order.
In case of any redemption at the election of the Company of less than all the
Securities of any series, the Company, at least 60 days prior to the Redemption
Date fixed by the Company (unless a shorter notice shall be satisfactory to the
Trustee), shall notify the Trustee of such Redemption Date, of the tenor and
terms of the Securities of such series to be redeemed and of the principal
amount of such Securities to be redeemed.  In the case of any redemption of
Securities prior to the expiration of any restriction on such redemption
provided in the terms of such Securities or elsewhere in this Indenture, the
Company shall furnish the Trustee with an Officers' Certificate evidencing
compliance with such restriction.

          SECTION 10.03.  Selection by Trustee of Securities to Be Redeemed.  
                          -------------------------------------------------    
If less than all the Securities of any series of like tenor and terms specified
by the Company are to be redeemed, the particular Securities to be redeemed
shall be selected not more than 60 days prior to the Redemption Date by the
Trustee, from the Outstanding Securities of such series and of such tenor and
terms 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 (equal to the minimum authorized denominations for such Securities
or any integral multiple thereof) of the principal amount of such Registered
Securities or such Bearer Securities or a denomination larger than the minimum
authorized denomination for such Registered Securities or such Bearer
Securities.

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

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

          SECTION 10.04.  Notice of Redemption.  Notice of redemption shall be
                          --------------------                                  
given in the manner provided in Section 7.02 not fewer than 30 or more than 60
days prior to the Redemption Date.  All notices of redemption shall state:

               (1)  the Redemption Date;

                                      62
<PAGE>
 
               (2)  the Redemption Price;

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

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

               (5)  the Place or Places of Payment where such Securities,
     together in the case of Bearer Securities with all coupons, if any,
     appertaining thereto maturing after the Redemption Date, are to be
     surrendered for payment of the Redemption Price;

               (6)  that Bearer Securities may be surrendered for payment only
     at such place or places that are outside the United States, except as
     provided in Section 3.02; and

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

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

          SECTION 10.05.  Deposit of Redemption Price.  On or prior to any
                          ---------------------------                       
Redemption Date, the Company shall deposit with the Trustee or with a Paying
Agent (or, if the Company is acting as its own Paying Agent, segregate and hold
in trust as provided in Section 3.04(b)) an amount of money sufficient to pay
the Redemption Price of, and (except if the Redemption Date shall be the same
date as the Stated Maturity of an installment of interest thereon) accrued
interest on, all the Securities that are to be redeemed on that date; provided,
however, that deposits with respect to Bearer Securities shall be made with a
Paying Agent or Paying Agents located outside the United States except as
otherwise provided in Section 3.02, unless otherwise specified as contemplated
by Section 2.01.

          SECTION 10.06.  Securities Payable on Redemption Date.  Notice of
                          -------------------------------------              
redemption having been given as aforesaid, the Securities so to be redeemed
shall become due and payable, on the Redemption Date, at the Redemption Price

                                      64
<PAGE>
 
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, such Security shall be paid by the
Company at the Redemption Price, together with accrued interest to the
Redemption Date; provided, however, that:  (i) 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 3.02); and (ii) installments of interest whose
Stated Maturity is on or prior to the Redemption Date shall be payable to the
holders of such Securities, or one or more Predecessor Securities, registered as
such at the close of business on the relevant record date for the payment of
such interest according to the terms of such Securities.

          If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant coupons maturing after the Redemption Date, such
Bearer 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
is furnished to them such security or indemnity as they may require to hold each
of them and any Paying Agent harmless.  If thereafter the holder of such Bearer
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 on
account of such coupon without interest thereon; provided, however, that
interest represented by coupons shall be payable only upon presentation and
surrender of those coupons at an office or agency located outside of the United
States except as otherwise provided in Section 3.02.

          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 or related coupon.

          SECTION 10.07.  Registered Securities Redeemed in Part.  Any
                          --------------------------------------        
Registered Security that is to be redeemed only in part shall be surrendered at
a Place of Payment therefor (with, if the Company or the Trustee so requires,
due 

                                      64

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 new Registered Securities of the same
series and of like tenor and terms, 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.

for by the terms of such series, provided that such Securities have not been

fund payment shall be reduced accordingly.

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

                    (D)  that all conditions precedent, if any, provided for in
          this Indenture have been complied with; and

                    (E)  that the execution and delivery by the Company of such
          Securities and coupons, if any, do not conflict with any law,
          administrative regulation or court decree known by legal counsel
          furnishing the Opinion of Counsel to be applicable to the Company.

or Securities or the nominee of such Depositary and (iii) shall be delivered by
the Trustee to such Depositary or pursuant to such Depositary's instruction.

          (f)  The Trustee shall have the right to decline to authenticate and
deliver any Securities under this Section 2.04 if the Trustee, being advised by
counsel, determines that such action may not lawfully be taken or if the Trustee
in good faith by its board of directors or trustees, executive committee or a
trust committee of directors or trustees or vice presidents shall determine that
such action would expose the Trustee to personal liability to existing holders.

          (g)  Notwithstanding any contrary provision herein, if all Securities
of a series are not to be originally issued at one time, it shall not be
necessary for the Company to deliver to the Trustee a Company Order, Officers'
Certificate, resolution of the Board of Directors, supplemental indenture or

to the authentication upon original issuance of the first Security of such
series to be issued.  In such event, any subsequent request by the Company to
the Trustee to authenticate Securities of such series upon original issuance
shall constitute a representation and warranty by the Company that, as of the
date of such request, the statements made in the Officers' Certificate or other
certificates delivered pursuant to Section 2.04(d) shall be true and correct as

Board of Directors or supplemental indenture delivered by the Company to the
Trustee in the circumstances set forth in this Section 2.04(g) may provide that
Securities that are the subject thereof will be authenticated and delivered by
the Trustee or its agent on original issue from time to time in the aggregate
principal amount established for such series pursuant to such procedures
acceptable to the Trustee as may be specified from time to time by Company Order

Board of Directors, such terms and conditions of said Securities as are
specified in such Company Order, supplemental indenture or resolution of the
Board of Directors.

          (h)  Each Depositary designated pursuant to clause (9) of Section 2.01
for a Global Security in registered form, at the time of its designation and at
all times while it serves as Depositary, shall be a clearing agency registered

benefits of this Indenture or be valid or obligatory for any purpose unless such
security bears thereon a certificate of authentication substantially in the form
set forth in Section 2.02, manually executed by an authorized signatory of the
Trustee.  Such certificate by the Trustee upon any Security executed by the
Company shall be conclusive evidence that the Security so authenticated has been
duly authenticated and delivered under this Indenture.  Except as permitted by
Section 2.07, the Trustee shall not authenticate and deliver any Bearer Security
unless all appurtenant coupons for interest then matured have been detached and
cancelled.  Notwithstanding the foregoing, if any Security or portions thereof
shall have been duly authenticated and delivered hereunder but never issued and
sold by the Company (whether because of failure of settlement or otherwise), and
the Company shall deliver such Security to the Trustee for cancellation as
provided in Section 2.10 together with a written statement stating that such
Security or portion thereof has never been issued and sold by the Company, for
all purposes of this Indenture such Security shall be deemed never 

                                      16
<PAGE>
 
to have been authenticated and delivered hereunder and shall not be entitled to
the benefits of this Indenture.

          (c)  In case any officer of the Company whose manual or facsimile
signature appears on any of the Securities or coupons shall cease to be such
officer before the Securities or coupons so signed shall have been authenticated
and delivered by the Trustee, or disposed of by the Company, such Securities or
coupons nevertheless may be authenticated and delivered or disposed of as though
the person whose manual or facsimile signature appears on such Securities or
coupons had not ceased to be such officer of the Company; and any Security or
coupon may bear the manual or facsimile signature on behalf of the Company by
such persons as, at the actual date of the execution of such Security or coupon,
shall be the proper officers of the Company, although at the date of the
execution of this Indenture any such person was not such an officer.

          SECTION 2.06.  Exchange and Registration of Transfer of Securities.
                         ---------------------------------------------------    
(a)  Registered Securities of any series may be exchanged for a like aggregate
principal amount of Registered Securities of other authorized denominations and
of like tenor and terms of the same series.  Registered Securities to be
exchanged shall be surrendered at the office or agency to be maintained by the
Company pursuant to Section 4.02 in each Place of Payment for such series of
Registered Securities, and the Company shall execute and cause to be registered,
and the Trustee shall authenticate and deliver in exchange therefor, the
Registered Security or Securities which the Securityholder making the exchange
shall be entitled to receive.

          (b)  For each series of Registered Securities, the Company shall cause
to be kept in at least one such office or agency a Security register (the
"Security Register") in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for registration of Registered Securities
and registration of transfer of Registered Securities as provided in this
Article Two.  Each such Security Register shall be in written form or in any
other form capable of being converted into written form within a reasonable
time.  At all reasonable times such Security Registers shall be open for
inspection by the Trustee.  Upon due presentment for registration of transfer of
any Registered Security of any series at any such office or agency, the Company
shall execute and register and the Trustee shall authenticate and deliver in the
name of the transferee or transferees a new Registered Security or Securities of
the same series and of like tenor and terms for an equal aggregate principal
amount.  Unless otherwise provided (pursuant to Section 2.01 or otherwise), the
Company initially appoints the 

                                      17
<PAGE>
 
Trustee, at the principal office of the Trustee, as a Security registrar for
each series of Registered Securities.

          (c)  All Registered Securities presented for registration of transfer
or for exchange or payment, if so required by the Company or the Trustee, shall
be duly endorsed by, or be accompanied by a written instrument or instruments of
transfer in form satisfactory to the Company and the Trustee duly executed by,
the holder or his attorney duly authorized in writing.

          (d)  To the extent specified in the manner provided by Section 2.01,
Registered Securities or Bearer Securities of any series may be issued in
exchange for Bearer Securities (except as otherwise specified in the manner
contemplated by Section 2.01 with respect to a Bearer Security in global form)
of the same series, of any authorized denomination and of like tenor and terms
and aggregate principal amount, upon surrender of the Bearer Securities to be
exchanged at any office or agency specified in the manner provided by Section
2.01, with all unmatured coupons and all unpaid matured coupons thereto
appertaining.  If the holder of a Bearer Security is unable to produce any such
unmatured coupon or coupons or unpaid matured coupon or coupons, 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 amount
represented by 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 hold
harmless each of them and any Paying Agent.  If thereafter the holder of such
Security shall surrender to any Paying Agent any such missing coupon in respect
of which such 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 4.02, interest represented by coupons shall be payable only
upon presentation and surrender of those coupons at an office or agency located
outside the United States.  Whenever any Securities are so surrendered for
exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Securities which the holder making the exchange is entitled to
receive.

          (e)  If at any time the Depositary for the Global Securities of a
series notifies the Company that it is unwilling or unable to continue as
Depositary for the Global Securities of such series or if at any time the
Depositary for the Registered Securities of such series shall no longer be
eligible under Section 2.03 because it no longer is a clearing agency registered
under the Securities Exchange Act of 1934 and any other applicable statute or
regulation, the Company shall appoint a successor Depositary with respect to the

                                      18
<PAGE>
 
Global Securities of such series.  If a successor Depositary for the Global
Securities of such series is not appointed by the Company within 90 days after
the Company receives such notice or becomes aware of such ineligibility, the
Company's election pursuant to Section 2.01(9) shall no longer be effective with
respect to the Securities of such series and the Company will execute, and the
Trustee, upon receipt of a Company Order for the authentication and delivery of
definitive Securities of such series, will authenticate and deliver Securities
of such series in definitive form in an aggregate principal amount equal to the
principal amount of the Global Security or Securities representing such series
in exchange for such Global Security or Securities.

          (f)  The Company at any time and in its sole discretion may determine
that the Securities of any series issued in the form of one or more Global
Securities shall no longer be represented by such Global Security or Securities.
In such event the Company will execute, and the Trustee, upon receipt of a
Company Order for the authentication and delivery of definitive Securities of
such series, will authenticate and deliver, Securities of such series in
definitive form and in an aggregate principal amount equal to the principal
amount of the Global Security or Securities representing such series in exchange
for such Global Security or Securities.

          (g)  If specified by the Company pursuant to Section 2.01 with respect
to a series of Securities, the Depositary for such series of Securities may
surrender a Global Security for such series of Securities in exchange in whole
or in part for Securities of such series of like tenor and terms and in
definitive form on such terms as are acceptable to the Company and such
Depositary.  Thereupon the Company shall execute, and the Trustee shall
authenticate and deliver:

               (i)  to each Person specified by such Depositary a new Security
     or new Securities of the same series, of like tenor and terms and of any
     authorized denomination as requested by such Person in aggregate principal
     amount equal to and in exchange for such Person's beneficial interest in
     the Global Security; and

              (ii)  to such Depositary a new Global Security of like tenor and
     terms and in a denomination equal to the difference, if any, between the
     principal amount of the surrendered Global Security and the aggregate
     principal amount of Securities delivered to holders thereof.

          (h)  In any exchange provided for in Section 2.06(e), Section 2.06(f)
or Section 2.06(g), the

                                      19
<PAGE>
 
Company will execute and the Trustee will authenticate and deliver Securities
(i) in definitive registered form in authorized denominations, if the Securities
of such series are issuable as Registered Securities, (ii) in definitive bearer
form in authorized denominations, with unmatured coupons attached, if the
Securities of such series are issuable as Bearer Securities or (iii) as either
Registered or Bearer Securities, if the Securities of such series are issuable
in either form; provided, however, that (A) no definitive Bearer Security shall
be delivered in exchange for a temporary Global Security unless the Company or
its agent shall have received from the person entitled to receive the definitive
Bearer Security a Bearer Security Tax Certificate, (B) delivery of a Bearer
Security shall occur only outside the United States and (C) no definitive Bearer
Security will be issued if the Company or the Trustee has reason to know that
such certificate is false.

          (i)  Upon the exchange of all of a Global Security for Securities in
certificated form, such Global Security shall be cancelled by the Trustee.  The
exchange of any portion of a Global Security for Securities in certificated form
shall be subject to Section 2.03(a).  Registered Securities issued in exchange
for all or part of a Global Security shall be registered in such names and in
such authorized denominations as the Depositary for such Global Security,
pursuant to instructions from its direct or indirect participants or otherwise,
shall instruct the Trustee.  The Trustee shall deliver such Registered
Securities to the persons in whose names such Securities are so registered.  The
Trustee shall deliver Bearer Securities issued in exchange for all or part of a
Global Security to the persons, and in such authorized denominations, as the
Depositary for such Global Security, pursuant to instructions from its direct or
indirect participants or otherwise, shall instruct the Trustee; provided,
however, that (A) no definitive Bearer Security shall be delivered in exchange
for all or part of a temporary Global Security unless the Company or its agent
shall have received from the person entitled to receive the definitive Bearer
Security a Bearer Security Tax Certificate, (B) delivery of a Bearer Security
shall occur only outside the United States and (C) no definitive Bearer Security
will be issued if the Company or the Trustee has reason to know that any such
certificate is false.

          (j)  No service charge shall be made for any exchange or registration
of transfer of Securities, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any such exchange or registration of transfer.

                                      20
<PAGE>
 
          (k)  The Company shall not be required (i) to issue, register the
transfer of or exchange Securities of any particular series during a period
beginning at the opening of business 15 days before the day of the mailing of a
notice of redemption of Securities of such series selected for redemption under
Section 11.03 and ending at the close of business on the day of such mailing,
(ii) to register the transfer of or exchange any Registered Security so selected
for redemption in whole or in part, except the unredeemed portion of any
Registered Security being redeemed in part or (iii) to exchange any Bearer
Security so selected for redemption except that such a Bearer Security may be
exchanged for a Registered Security of that series, provided that such
Registered Security shall be surrendered immediately for redemption with written
instruction for payment consistent with the provisions of this Indenture.

          (l)  Notwithstanding anything herein to the contrary:  the exchange of
Bearer Securities for Registered Securities shall be subject to applicable laws
and regulations in effect at the time of exchange; and neither the Company nor
the Trustee or any Security registrar shall exchange any Bearer Securities into
Registered Securities if it has received an Opinion of Counsel that as a result
of such exchanges the Company could suffer adverse consequences under the United
States Federal income tax laws and regulations then in effect and the Company
has delivered to the Trustee a Company Order directing the Trustee not to make
such exchanges thereafter unless and until the Trustee receives a subsequent
Company Order to the contrary.  The Company shall deliver copies of such Company
Order to the Security registrar.

          SECTION 2.07.  Mutilated, Destroyed, Lost or Stolen Securities. (a)
                         -----------------------------------------------  
In case any temporary or definitive Security of any series or any related coupon
shall become mutilated or be destroyed, lost or stolen, the Company in its
discretion may execute, and upon its request and in the absence of notice to the
Company and the Trustee that such Security or coupon has been acquired by a bona
fide purchaser, the Trustee shall authenticate and deliver a new Security of the
same series or related coupon, of equal aggregate principal amount and of like
tenor and terms bearing a number not contemporaneously outstanding, in exchange
and substitution for the mutilated Security or coupon, or in lieu of and in
substitution for the Security or coupon so destroyed, lost or stolen.  In every
case the applicant for a substituted Security or coupon shall furnish to the
Company and to the Trustee such security or indemnity as may be required by them
to hold each of them harmless, and, in every case of destruction, loss or theft,
the applicant also shall furnish to the Company and to the Trustee evidence to
their satisfaction of the destruction, 

                                      21
<PAGE>
 
loss or theft of such security or coupon and of the ownership of such Security
or coupon.

          (b)  The Trustee may authenticate any such substitute Security and
deliver the same upon the written request or authorization of any officer of the
Company.  Upon the issuance of any substitute Security or coupon, 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
reasonable expenses (including the fees and expenses of the Trustee) connected
therewith.  In case any Security or coupon which has matured or is about to
mature shall become mutilated or be destroyed, lost or stolen, the Company,
instead of issuing a substitute Security or coupon, may pay or authorize the
payment of the same (without surrender thereof except in the case of a mutilated
Security or coupon) if the applicant for such payment shall furnish to the
Company and to the Trustee such security or indemnity as may be required by them
to hold each of them harmless and, in the case of destruction, loss or theft,
evidence satisfactory to the Company and the Trustee of the destruction, loss or
theft of such Security or coupon and of the ownership of such Security or
coupon.

          (c)  Every substitute Security or coupon issued pursuant to the
provisions of this Section 2.07 by virtue of the fact that any Security or
coupon is destroyed, lost or stolen shall constitute an additional contractual
obligation of the Company, whether or not the destroyed, lost or stolen Security
or coupon shall be found at any time, and shall be entitled to all the benefits
of this Indenture equally and proportionately with any and all other Securities
or coupons of the relevant series duly issued under this Indenture.  All
Securities or coupons shall be held and owned by the holders upon the express
condition that the foregoing provisions are exclusive with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities or
coupons and shall preclude any and all other rights or remedies notwithstanding
any law or statute existing or hereafter enacted to the contrary with respect to
the replacement or payment of negotiable instruments or other securities without
their surrender.

          (d)  Notwithstanding the foregoing, the payment of principal of and
any premium and interest on Bearer Securities, except as otherwise provided in
Section 4.02, shall be payable only at an office or an agency located outside of
the United States, and, with respect to any coupons, interest represented
thereby shall be payable only upon presentation and surrender of such coupons.

          SECTION 2.08.  Temporary Securities.  (a)  Pending the preparation
                         --------------------                                 
of definitive Securities of any series, the Company may execute and the Trustee
shall authenticate and deliver temporary Securities (printed or lithographed).
Temporary Securities shall be issuable in any authorized denomination, and
substantially in the form of the definitive Securities of such series (and of
like tenor and terms) in lieu of which they are issued in registered form or, if
authorized, in bearer form with one or more coupons or without coupons, but with
such omissions, insertions and variations as may be appropriate for temporary
Securities, all as may be determined by the Company.  In the case of Securities
of any series issuable as Bearer Securities, such temporary Securities may be in
global form, representing all or any part of the Outstanding Securities of such
series.

          (b)  Unless otherwise provided pursuant to Section 2.01:

               (i)  Except in the case of temporary Securities in global form,
     every such temporary Security shall be authenticated by the Trustee in
     substantially the same manner, and with the same effect, as the definitive
     Securities.  Without unreasonable delay the Company will execute and
     deliver to the Trustee definitive Securities of such series and thereupon
     any or all temporary Securities of such series (accompanied, if applicable,
     by all unmatured coupons and all unpaid matured coupons appertaining
     thereto) may be surrendered in exchange therefor at the principal office of
     the Trustee, and the Trustee shall authenticate and deliver in exchange for
     such temporary Securities an equal aggregate principal amount of definitive
     Securities of such series of authorized denominations.  Such exchange shall
     be made at the Company's expense and without any charge to the holder.
     Until so exchanged, the temporary Securities of any series in all respects
     shall be entitled to the same benefits under this Indenture as definitive
     Securities of such series authenticated and delivered under this Indenture.
     Notwithstanding the foregoing, no Bearer Security shall be delivered in
     exchange for a Registered Security, and a Bearer Security shall be
     delivered in exchange for a Bearer Security only in compliance with the
     conditions set forth in Section 2.06.

              (ii)  If Securities of any series are issued in temporary global
     form, any such temporary Global Security, unless otherwise provided
     pursuant to Section 2.01, shall be delivered to the Depositary for the
     benefit of Euro-clear and CEDEL S.A. for credit to 

                                      23
<PAGE>
 
     the respective accounts of the beneficial owners of such Securities or to
     such other accounts as they may direct.

             (iii)  Any such temporary Global Security shall be exchangeable, on
     the terms and in the manner set forth therein, in whole or in part, for an
     equal aggregate principal amount of definitive Securities of the same
     series of authorized denominations and of like tenor and terms as the
     portions of such temporary Global Security to be exchanged.  Any definitive
     Bearer Security shall be delivered in exchange for a portion of a temporary
     Global Security only upon receipt by the Trustee from the Person entitled
     to receive such definitive Bearer Security of a Bearer Security Tax
     Certificate.

              (iv)  Until exchanged in full as hereinabove provided, the
     temporary Securities of any series shall be entitled in all respects to the
     same benefits under this Indenture as definitive Securities of the same
     series and of like tenor and terms authenticated and delivered hereunder,
     except that any interest payable with respect to a temporary Global
     Security will be paid as specified therein.

          SECTION 2.09.  Payment of Interest; Interest Rights.  Interest on any
                         ------------------------------------                
Registered Security which is payable, and is punctually paid or duly provided
for, on any Interest Payment Date shall be paid to the Person in whose name that
Registered Security (or one or more Predecessor Securities) is registered at the
close of business on the Regular Record Date for such interest. In case a Bearer
Security of any series is surrendered in exchange for a Registered Security of
such series after the close of business (at an office or agency in a Place of
Payment for such series) on any Regular Record Date and before the opening of
business (at such office or agency) on the next succeeding Interest Payment
Date, such Bearer Security shall be surrendered without the coupon relating to
such Interest Payment Date and interest will not be payable on such Interest
Payment Date in respect of the Registered Security issued in exchange for such
Bearer Security, but will be payable only to the holder of such coupon when due
in accordance with the provisions of this Indenture. Payment of interest on any
Registered Security may be made as provided in Section 3.02. Except as otherwise
provided in the terms of any particular series pursuant to Section 2.01.
interest will be calculated on the basis of a year consisting of twelve 30-day
months.

          Any interest on any Security that is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date ("Defaulted Interest")
forthwith shall cease to be payable to the holder on the relevant Regular Record
Date 

                                      24
<PAGE>
 
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 (i) or (ii)
below:

               (i)  The Company may elect to make payment of any Defaulted
     Interest to the Persons in whose names such Securities (or their respective
     Predecessor Securities) are registered at the close of business on a
     Special Record Date for the payment of such Defaulted Interest, which shall
     be fixed in the following manner.  The Company shall notify the Trustee in
     writing of the amount of Defaulted Interest proposed to be paid on each
     Security and the date of the proposed payment, and at the same time the
     Company shall deposit with the Trustee an amount of money equal to the
     aggregate amount proposed to be paid in respect of such Defaulted Interest
     or shall make arrangements satisfactory to the Trustee for such deposit
     prior to the date of the proposed payment, such money when deposited to be
     held in trust for the benefit of the Persons entitled to such Defaulted
     Interest as provided in this clause (i).  Thereupon the Trustee shall fix a
     Special Record Date for the payment of such Defaulted Interest which shall
     be not more than 15 nor fewer than ten days prior to the date of the
     proposed payment and not fewer than ten days after the receipt by the
     Trustee of the notice of the proposed payment.  The Trustee promptly shall
     notify the Company of such Special Record Date and, in the name and at the
     expense of the Company, shall cause notice of the proposed payment of such
     Defaulted Interest and the Special Record Date therefor to be mailed, first
     class, postage prepaid, to each holder at his address as it appears in the
     Security Register, not fewer than ten days prior to such Special Record
     Date.  Notice of the proposed payment of such Defaulted Interest and the
     Special Record Date therefor having been given as aforesaid, such Defaulted
     Interest shall be paid to the Persons in whose names the Securities (or
     their respective Predecessor Securities) are registered on such Special
     Record Date and shall no longer be payable pursuant to the following clause
     (ii).

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

                                      25
<PAGE>
 
          Subject to the foregoing provisions of this Section 2.09, each
Security of any series delivered under this Indenture upon registration of
transfer of or in exchange for or in lieu of any other Security of such series
shall carry the rights to interest accrued and unpaid, and to accrue, that were
carried by such other Security.

          Subject to the limitations set forth in Section 4.02, the holder of
any coupon appertaining to a Bearer Security shall be entitled to receive the
interest payable on such coupon upon presentation and surrender of such coupon
on or after the Interest Payment Date of such coupon at an office or agency
maintained for such purpose pursuant to Section 4.02.

          SECTION 2.10.  Cancellation of Securities Paid, etc.    All Securities
                         ------------------------------------                   
and coupons surrendered for the purpose of payment, exchange or registration of
transfer, if surrendered to the Company or any Paying Agent or any Security
registrar, shall be delivered to the Trustee and promptly cancelled by the
Trustee, or, if surrendered to the Trustee, promptly shall be cancelled by it;
and no Securities or coupons shall be issued in lieu thereof except as expressly
permitted by any of the provisions of this Indenture.  The Trustee may destroy
cancelled Securities or coupons and will deliver a certificate of such
destruction to the Company.

coupons by such holders acceptance of a Security or coupon likewise covenants
and agrees that, subject to the provisions of Article Fourteen, the payment of
the principal of and any premium and interest on any and all Securities and
coupons is expressly subordinated hereby, to the extent and in the manner set
forth in this Article Three, to the prior payment in full of all Senior
Indebtedness.  The provisions of this Article Three shall constitute a
continuing offer to all persons who, in reliance upon such provisions, become
holders of, or continue to hold, Senior Indebtedness, and such provisions are
made for the benefit of the holders of Senior Indebtedness, and such holders are
hereby made obligees under this Article Three as if their names were written in
this Article Three as such, and they and each of them may proceed to enforce the
provisions of this Article Three.

          SECTION 3.02.  Company Not to Make Payments with Respect to Securities
                         -------------------------------------------------------
in Certain Circumstances.  (a)  If payment of the Securities is accelerated
- ------------------------                                                     
because of an Acceleration Event, the Company promptly shall notify holders of
Senior Indebtedness of the acceleration.

          (b)  The Company may not pay principal of or any premium or interest
on the Securities and may not acquire any Securities for cash or property other
than capital stock of the Company if:

               (1)  a default on Senior Indebtedness occurs and is continuing
     that permits holders of such Senior Indebtedness to accelerate its
     maturity; and

               (2)  such default is the subject of judicial proceedings or the
     Company receives written notice of such default from a representative of
     the holders of such Senior Indebtedness.  If the Company receives any such
     notice, a similar notice received within 360 days thereafter relating to
     the same default on the same issue of Senior Indebtedness shall not be
     effective for purposes of this Section 3.02(b).

          The Company may resume payments on the Securities and may acquire them
when:

               (i)  such default is cured or waived or shall have ceased to
     exist or the Senior Indebtedness to which such default relates shall have
     been paid in full in cash or cash equivalent; or

              (ii)  if such default is not the subject of judicial proceedings,
     120 days pass after such written notice is received by the Company, but
     only if this Article Three does not otherwise prohibit such payment or
     acquisition at that time.

          (c)  In the event that notwithstanding the provisions of this Section
3.02 the Company shall make any payment to the Trustee on account of the
principal of or any premium or interest on the Securities prohibited by Section
3.02(b), then, unless and until such payment is thereafter permitted under
Section 3.02(b), such payment shall be held by the Trustee in trust for the

Senior Indebtedness (pro rata as to each of such holders on the basis of the
respective amounts of Senior Indebtedness held by them) or their representative

          (c)  In the event that notwithstanding the foregoing provisions of
     this Section 3.03, any payment or distribution of assets of the Company of
     any kind or character, whether in cash, property or securities (other than

subrogated to the rights of the holders of Senior Indebtedness to receive

For the purpose of such subrogation, no payments or distributions to the holders
of the Senior Indebtedness (whether by or on behalf of the Company or by or on
behalf of the holders of the Securities or any related coupons) by virtue of
this Article Three that otherwise would have been made to the holders of the
Securities or coupons shall be deemed, as between the Company and the holders of
the Securities and coupons, to be payment by the Company to or on account of the
Senior Indebtedness.

          SECTION 3.05.  Obligation of the Company Unconditional, etc.  The
                         --------------------------------------------        
provisions of this Article Three are and are intended solely for the purpose of
defining the relative rights of the holders of the Securities and any related
coupons on the one hand and the holders of the Senior Indebtedness on the other
hand.  Nothing contained in this Article Three or elsewhere in this Indenture or
in the Securities is intended to or shall impair, as between the Company and the
holders of the Securities, the obligation of the Company, which is absolute and
unconditional, to pay to the holders of the Securities the principal of and any
premium and interest on the Securities as and when the same shall become due and
payable in accordance with their terms, or is intended to or shall affect the
relative rights of the holders of the Securities or the coupons and creditors of
the Company other than the holders of the Senior Indebtedness, nor shall
anything in this Article Three or elsewhere in this Indenture prevent the
Trustee or the holder of any Security or coupon from exercising all remedies
otherwise permitted by applicable law upon default under this Indenture, subject
to the rights, if any, under this Article Three of the holders of Senior
Indebtedness in respect of cash, property or securities of the Company received
upon the exercise of any such remedy.  Nothing contained in this Article Three
is intended to alter the rights between the holders of the Securities and any
related coupons and the Company's creditors other than the holders of the
Securities or coupons and the holders of Senior Indebtedness.  Upon any payment
or distribution of assets of

the Company referred to in this Article Three, the Trustee, subject to the
provisions of Section 6.01, and the holders of the Securities and any related
coupons shall be entitled to rely upon any order or decree made by any court of
competent jurisdiction in which any dissolution, winding up, liquidation or
reorganization proceedings are pending, or a certificate of the liquidating
trustee or agent or other person making any distribution to the Trustee or to
the holders of the Securities and coupons, for the purpose of ascertaining the
persons entitled to participate in such distribution, the holders of, the
amounts of, the amounts payable on, the amount or amounts paid or distributed on
and all other facts pertinent to the Senior Indebtedness and other indebtedness
of the Company and all other facts pertinent to this Article Three.

          SECTION 3.06.  Trustee Entitled to Assume Payments Not Prohibited in
                         -----------------------------------------------------
Absence of Notice.  The Company shall give prompt written notice to a

Responsible Officer of the Trustee located at its principal office of any fact
known to the Company that would prohibit, pursuant to this Article Three, the
making of any payment to or by the Trustee with respect to the Securities or any
related coupons.  Notwithstanding the provisions of Section 3.01 or Section 3.02
or any other provision of this Indenture, the Trustee shall not at any time be
charged with knowledge of the existence of any fact that would prohibit the
making of any payment of money to or by the Trustee, unless and until the
Trustee shall have received at the principal office of the Trustee written
notice of such facts from the Company or from one or more holders of Senior
Indebtedness or from any trustee for such holders; and, prior to the receipt of
any such written notice, the Trustee, subject to the provisions of Section 6.01,
shall be entitled to assume that no such facts exist.

          SECTION 3.07.  Application by Trustee of Money Deposited with It.
                         -------------------------------------------------    
Anything in this Indenture to the contrary notwithstanding, any deposit of money
by the Company with the Trustee (whether or not in trust) for the payment of the
principal of or any premium or interest on any Securities or coupons shall be
subject to the provisions of Sections 3.01, 3.02, 3.03 and 3.04 except that, if
not fewer than three Business Days prior to the date on which by the terms of
this Indenture any such money may become payable for any purpose (including
without limitation the payment of principal of or any premium or interest on any
Security and any amounts immediately due and payable upon the execution of any
instrument acknowledging satisfaction and discharge of this Indenture as
provided in Article Fourteen) the Trustee shall not have received with respect
to such money the notice provided for in Section 3.06, then, anything contained
in this Article Three to the contrary notwithstanding, the Trustee 

                                      31
<PAGE>
 
shall have full power and authority to receive such money and to apply the same
to the purpose for which it was received, and shall not be affected by any
notice to the contrary that may be received by it during such three Business Day
period.

          SECTION 3.08.  Article Applicable to Paying Agents.  In case at any
                         -----------------------------------                   
time any Paying Agent other than the Trustee shall have been appointed by the
Company and be then acting under this Indenture, the term "Trustee" as used in
this Article Three shall be construed (unless the context otherwise requires) as
extending to and including such Paying Agent within its meaning as fully for all
intents and purposes as if such Paying Agent were named in this Article Three in
addition to or in place of the Trustee.

          SECTION 3.09.  Subordination Rights Not Impaired by Acts or Omissions
                         ------------------------------------------------------
of Company or Holders of Senior Indebtedness.  No right of any present or
- --------------------------------------------                               
future holder of any Senior Indebtedness to enforce subordination as provided in
this Article Three shall be prejudiced or impaired at any time in any way by any
act or failure to act on the part of the Company or by any act or failure to
act, in good faith, by any such holder, or by any noncompliance by the Company
with the terms, provisions and covenants of this Indenture, regardless of any
knowledge of such act, failure to act or noncompliance which any such holder may
have or otherwise be charged with.

          SECTION 3.10.  Securityholders Authorize Trustee to Effectuate
                         -----------------------------------------------
Subordination of Securities.  Each holder of the Securities by his acceptance of
- ---------------------------                                                    
a Security authorizes and expressly directs the Trustee on his behalf to take
such action as may be necessary or appropriate to effectuate the subordination
provided in this Article Three and appoints the Trustee his attorney-in-fact for
such purpose, including in the event of any dissolution, winding up, liquidation
or reorganization of the Company (whether in bankruptcy, insolvency or
receivership proceedings or upon an assignment for the benefit of creditors or
otherwise), action tending towards liquidation of the business and assets of the
Company, the immediate filing of a claim for the unpaid balance of its or his
Securities in the form required in such proceedings and action causing such
claim to be approved. If the Trustee does not file a proper claim or proof of
debt in the form required in such proceeding prior to 30 days before the
expiration of the time to file such claim or claims, then the holder or holders
of Senior Indebtedness hereby are authorized to and have the right to file an
appropriate claim for and on behalf of the holders of such Securities.

          SECTION 3.11.  Right of Trustee to Hold Senior Indebtedness.  The
                         --------------------------------------------

respect of any Senior

<PAGE>
 
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.

          SECTION 3.12.  Article Three Not to Prevent Events of Default.  The
                         ----------------------------------------------        
failure to make a payment on account of principal or any premium or interest by
reason of any provision in this Article Three shall not be construed as
preventing the occurrence of an Event of Default under Section 5.01.

          SECTION 3.13.  Trustee Not Fiduciary for Holders of Senior
                         -------------------------------------------
Indebtedness.  The Trustee shall not be deemed to owe any fiduciary duty to the

holders of Senior Indebtedness and shall not be liable to any such holders if it
shall in good faith mistakenly pay over or distribute to holders of Securities
or to the Company or to any other Person cash, property or securities to which
any holders of Senior Indebtedness shall be entitled by virtue of this Article
Three or otherwise.

                      PARTICULAR COVENANTS OF THE COMPANY

          SECTION 4.01.  Payment of Principal and Interest.  The Company duly
                         ---------------------------------                     
and punctually will pay or cause to be paid the principal of and any premium and
interest on the Securities of each series at the places, at the respective times
and in the manner provided in this Indenture and in the Securities.  Any
interest due on Bearer Securities on or before Maturity shall be payable only
upon presentation and surrender of the several coupons for such interest
installments as are evidenced thereby as they severally mature.

          SECTION 4.02.  Offices for Notices and Payments, etc.  So long as any
                         -------------------------------------               
Securities of a series remain Outstanding, the Company will maintain in each
Place of Payment for such series of Securities an office or agency where the
Securities of that series (but, except as otherwise provided below, unless such
Place of Payment is located outside the United States, not Bearer Securities)
may be presented for payment, for registration of transfer and for exchange as
provided in this Indenture and where notices and demands to or upon the Company
in respect of the Securities or of this Indenture may be served. If Securities
of a series are issuable as Bearer Securities, the Company will maintain,
subject to any laws or regulations applicable thereto, an office or agency in a
Place of Payment for such series that is located outside the United States where
Securities of such 

                                      33
<PAGE>
 
series and the related coupons may be presented for payment. The Company will
give to the Trustee prompt written notice of the location of each such office or
agency and of any change of location thereof. In case the Company shall fail to
maintain any such office or agency or shall fail to give such notice of the
location or of any change in the location thereof, presentations and demands may
be made and notices may be served at the principal office of the Trustee, and
the Company hereby initially appoints the Trustee its agent to receive all such
presentations and demands, except that Bearer Securities of that series and the
related coupons may be presented for payment at the place specified for that
purpose pursuant to Section 2.01(5). Unless otherwise provided pursuant to
Section 2.01, the Company hereby initially designates as the Place of Payment
for each series of Securities (other than Bearer Securities of that series and
the related coupons) the Borough of Manhattan, The City of New York, New York
and appoints the Trustee, at the principal office of the Trustee, as Paying
Agent in such city. Notwithstanding any other provisions to the contrary, the
Company at its option may make payment of principal and any premium and interest
with respect to any Registered Security by check mailed to the Person entitled
thereto, as such address appears on the Security Register, except that a holder
of $10,000,000 or more in aggregate principal amount of Securities of such
series and of like tenor and terms will be entitled to receive payments by wire
transfer of immediately available funds if appropriate wire transfer
instructions shall have been received in writing by the Trustee not later than
ten Business Days prior to the applicable payment date.

          No payment of principal of or any premium or interest on Bearer
Securities shall be made at any office or agency of the Company 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, that payment of principal of and any premium and interest on any Bearer
Security may be made at an office or agency of, and designated by, the Company
located in the United States if (but only if) payment of the full amount of such
principal, premium or interest at all offices outside the United States
maintained for the purpose by the Company in accordance with this Indenture is
illegal or effectively precluded by exchange controls or other similar
restrictions and the Trustee receives an Opinion of Counsel that such payment
within the United States is legal.  Unless otherwise provided as contemplated by
Section 2.01 with respect to any series of Securities, at the option of the
holder of any Bearer Security or related coupon payment may be made by mailing a
check to an address outside the United States or by transfer to an account
maintained by the payee with a bank located outside the United States.

                                      34

          The Company also from time to time may designate one more offices or
agencies (in or outside of such Place of Payment) where the Securities of one or
more series and any appurtenant coupons (subject to the preceding paragraph) may
be presented or surrendered for any and all such purposes, and from time to time
may rescind such designations.  The Company will give prompt written notice to
the Trustee of any such designation and any change in the location of any such
office or agency.

          SECTION 4.03.  Provisions as to Paying Agent.  (a)  The Company, with
                         -----------------------------                      
respect to the Securities of each series, prior to each due date of principal of
or any premium or interest on such Securities, will deposit with the Paying
Agent for such Securities a sum sufficient to pay the principal, premium or
interest so becoming due, such sum to be held in trust for the benefit of the
persons entitled to such principal, premium or interest. If the Company shall
appoint a Paying Agent other than the Trustee with respect to the Securities of
any series, the Company will notify the Trustee of its making, or failure to
make, any such payment; and the Company also shall cause any such Paying Agent
to execute and deliver to the Trustee an instrument in which such agent shall
agree with the Trustee, subject to the provisions of this Section 4.03, as
follows:

               (1)  that it will hold all sums held by it as such agent for the
     payment of the principal of or any premium or interest on such Securities
     (whether such sums have been paid to it by the Company or by any other
     obligor on such Securities) in trust for the benefit of the Persons
     entitled thereto;

               (2)  that it will give the Trustee notice of any failure by the
     Company (or by any other obligor on such Securities) to make any payment of
     the principal of or any premium or interest on such Securities when the
     same shall be due and payable; and

               (3)  that it forthwith will pay to the Trustee, at any time
     during the continuance of an Event of Default, upon the written request of
     the Trustee, all sums so held by it as such agent.

          (b)  If the Company shall act as its own Paying Agent with respect to
the Securities of any series, on or before each due date of the principal of or
any premium or interest on the Securities of such series, it will set aside,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay such principal, premium or interest so becoming due and
will notify the Trustee of any failure to take such action and of any failure 

                                      35
<PAGE>
 
by the Company (or by any other obligor under such Securities) to make any
payment of the principal of or any premium or interest on such Securities when
the same shall become due and payable.

          (c)  Notwithstanding anything in this Section 4.03 to the contrary,
the Company, at any time, for the purpose of obtaining a satisfaction and
discharge of this Indenture or for any other reason, may pay or by Company Order
direct any Paying Agent to pay to the Trustee all sums held in trust by the
Company or any Paying Agent under this Indenture, such sums to be held by the
Trustee upon the trusts contained in this Indenture.

          (d)  Notwithstanding anything in this Section 4.03 to the contrary,
the agreement to hold sums in trust as provided in this Section 4.03 is subject
to Section 14.03 and Section 14.04.

          SECTION 4.04.  Statement as to Compliance.  The Company will deliver
                         --------------------------                             
to the Trustee, within 120 days after the end of each calendar year commencing
with the first calendar year following the issuance of Securities of any series
under this Indenture, a written certificate of the principal executive officer,
the principal financial officer or the principal accounting officer of the
Company, covering the period from the date of issuance of such Securities to the
end of the calendar year in which such Securities were issued, in the case of
the first such certificate, and covering the preceding calendar year, in the
case of each subsequent certificate, stating, as to each signer of such
certificate, that:

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

               (2)  to the best of his knowledge, based on such review, the
     Company has fulfilled all its conditions and covenants under this Indenture
     throughout such year, or, if there has been a default in the fulfillment of
     any such condition or covenant, specifying each such default known to him
     and the nature and status of such default; and

               (3)  such certificate sets forth as of the end of such year a
     list of all Principal Constituent Banks.

          SECTION 4.05.  Notice of Defaults.  The Company will deliver to the

5.01.

     securities convertible into or options, warrants or rights to subscribe for
     or purchase shares of, Voting Stock of a Principal Constituent Bank, and
     will not permit a Principal Constituent Bank to issue any shares of, or
     securities convertible into or options, warrants or rights to subscribe for
     or purchase shares of, such Voting Stock if, in each case, after giving
     effect to any such transaction, the Principal Constituent Bank would cease
     to be a Controlled Subsidiary; or

          (b)  permit a Principal Constituent Bank to:

                   (i)   merge or consolidate with any other corporation, unless
          the surviving corporation is, or upon consummation of the merger or
          consolidation will become, the Company or a Controlled Subsidiary; or

                  (ii)   lease, sell or transfer all or substantially all its
          properties and assets to any corporation or other Person, except to
          the Company or a Controlled Subsidiary or a Person that, upon such
          lease, sale or transfer, will become the Company or a Controlled
          Subsidiary.

          Notwithstanding the foregoing, any such sale, assignment, transfer or
other disposition of securities, any such merger or consolidation or any such
lease, sale or transfer of properties and assets shall not be prohibited if
required (i) by any law or any rule, regulation or order of any governmental
agency or authority or (ii) as a condition imposed by any law or any rule,
regulation or order of any governmental agency or authority with respect to the
acquisition by the Company or any Controlled Subsidiary, directly or indirectly,
through purchase of securities or assets, or a merger, consolidation or
otherwise, of any Person, provided that after giving effect to such acquisition
(A) such Person will be a Controlled Subsidiary, (B) the Consolidated Net
Banking Assets of the Company will be at least equal to the Consolidated Net
Banking Assets of the Company prior thereto and (C) BB&T-NC will be a Controlled

                         -------------------------------                      
the Securities shall be outstanding, the Company will not create, assume, incur
or suffer to be created, assumed or incurred or to exist any pledge, encumbrance
or lien, as security for indebtedness for borrowed money, upon any shares of, or
securities convertible into or options, warrants or rights to subscribe for or
purchase shares of, Voting Stock of a Principal Constituent Bank now or
hereafter owned by the Company, directly or indirectly, if, treating such
pledge, encumbrance or lien as a transfer of the shares of, or securities
convertible into or options, warrants or rights to subscribe for or purchase
shares of, Voting Stock subject thereto to the secured party, the Principal
Constituent Bank would not be a Controlled Subsidiary.

preserve and keep in full force and effect its corporate existence, rights
(charter and statutory) and franchises; provided, however, that the Company

Directors shall determine that the preservation thereof is no longer desirable
in the conduct of the business of the Company and that the loss thereof is not
disadvantageous in any material respect to the Securityholders.

     (other than indebtedness of any Subsidiary owing to the Company or to
     another Subsidiary), whether such indebtedness now exists or shall be
     created hereafter, shall happen and (i) not less than $1,000,000 of such

          (f)  failure on the part of the Company duly to observe or perform any

     specifically is provided for elsewhere in this Section 5.01 or which
     expressly has been included in this Indenture solely for the benefit of one
     or more series of Securities other than such series), and continuance of
     such failure for a period of 90 days after the date on which written notice
     of such failure, requiring the Company to remedy the same, shall have been
     given to the Company by the Trustee, or to the Company and the Trustee by

     aggregate principal amount of the Securities of such series at the time
     Outstanding;

          (g)  a court or governmental authority having jurisdiction in the
     premises shall enter a decree or order for relief in respect of the Company
     or a Principal Constituent Bank in an involuntary case under any applicable
     bankruptcy, insolvency or other similar law now or hereafter in effect, or
     appointing a receiver, liquidator, assignee, custodian, trustee,
     sequestrator (or similar official) of the Company or a Principal
     Constituent Bank or for any substantial part of its property, or ordering
     the winding up or liquidation of its affairs and such decree or order shall
     remain unstayed and in effect for a period of 60 consecutive days; or

          (h)  the Company or a Principal Constituent Bank shall commence a
     voluntary case under any applicable bankruptcy, insolvency or other similar
     law now or hereafter in effect, or shall consent to the entry of an order
     for relief in an involuntary case under any such law, or shall consent to
     the appointment of or taking possession by a receiver, liquidator,
     assignee, trustee, custodian, sequestrator (or similar official) of the
     Company or a Principal Constituent Bank or for substantially all of its
     property (other than the appointment of a conservator with repect to any
     Constituent Bank insured by the Federal Deposit Insurance Corporation or
     any successor agency), or shall make any general assignment for the benefit
     of creditors, or shall fail generally to pay its debts as they become due
     or shall take any corporate action in furtherance of any of the foregoing.

          If an Acceleration Event with respect to the Securities of any series
at the time Outstanding occurs and is continuing, then and in each such case,
unless the principal of all the Securities of such series already shall have
become due and payable, either the Trustee or the holders of not less than 25%
in aggregate principal amount of the Securities of such series then Outstanding,
by notice in writing to the Company (and to the Trustee if given by
Securityholders), may declare the principal amount of all the Securities of that
series to be due and payable immediately, and upon any such declaration the same
shall become and shall be immediately due and payable.  This provision, however,
is subject to the condition that, at any time after such a declaration of
acceleration, and before any judgment or decree for the payment of the money due
shall have been obtained or entered as hereinafter provided, the holders of a
majority in aggregate principal amount of the Securities of such series 

                                      40
<PAGE>
 
then Outstanding, by written notice to the Company and to the Trustee, may waive
all defaults and rescind and annul such declaration and its consequences, if:

               (1)  the Company shall pay or shall deposit with the Trustee a
     sum sufficient to pay:

                    (A)  all matured installments of interest on all the
          Securities of that series and the principal of and any premium on any
          and all Securities of that series that shall have become due otherwise
          than by acceleration (with interest on overdue installments of
          interest (to the extent that payment of such interest is enforceable
          under applicable law) and on such principal and premium at the rate
          borne by the Securities of that series, to the date of such payment or
          deposit); and

                    (B)  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

               (2)  any and all defaults with respect to Securities of that
     series under this Indenture, other than the nonpayment of principal of and
     any premium and accrued interest on Securities that shall have become due
     by acceleration, shall have been cured or waived as provided in Section
     5.07.

          No such waiver or rescission and annulment shall extend or shall
affect any subsequent default or shall impair any right consequent thereon.

          In case the Trustee or any Securityholder shall have proceeded to
enforce any right under this Indenture and such proceedings shall have been
discontinued or abandoned because of such rescission or annulment or for any
other reason or shall have been determined adversely to the Trustee or any
Securityholder, then and in every such case the Company, the Trustee and such
Securityholders, subject to any determination in such proceeding, shall be
restored respectively to their several positions and rights under this
Indenture, and all rights, remedies and powers of the Company, the Trustee and
such Securityholders shall continue as though no such proceeding had been taken.

          SECTION 5.02.  Payment of Securities on Default; Suit Therefor.  (a)
                         ----------------------------------------------- 
Subject to the provisions of Article Three, in case default shall be made in the
payment of (i) any installment of interest upon any of the Securities as and
when the same shall become due and payable, and such default shall 

                                      41
<PAGE>
 
have continued for a period of 30 days, or (ii) the principal of or any premium
on any of the Securities as and when the same shall have become due and payable
whether at Maturity of the Securities, by declaration or otherwise, then, upon
demand of the Trustee, the Company will pay to the Trustee, for the benefit of
the holders of the Securities, the whole amount that then shall have become due
and payable on all such Securities for principal, premium or interest, or any
combination thereof, as the case may be, with interest upon the overdue
principal and premium and (to the extent that payment of such interest is
enforceable under applicable law) upon the overdue installments of interest, at
the rate borne by the Securities; and, in addition, such further amount as shall
be sufficient to cover the costs and expenses of collection, including
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents, attorneys and counsel.

          (b)  In case the Company shall fail forthwith to pay such amounts upon
such demand, the Trustee, in its own name and as trustee of an express trust,
shall be entitled and empowered to institute any actions or proceedings at law
or in equity for the collection of the sums so due and unpaid, and may prosecute
any such action or proceeding to judgment or final decree, and may enforce any
such judgment or final decree against the Company or any other obligor on the
Securities and coupons and collect in the manner provided by law out of the
property of the Company or any other obligor on the Securities and coupons,
wherever situated, the money adjudged or decreed to be payable.

          (c)  In case there shall be pending proceedings for the bankruptcy or
for the reorganization of the Company or any other obligor on the Securities and
coupons under Title 11 of the United States Code or any other applicable law, or
in case a receiver or trustee shall have been appointed for the property of the
Company or such other obligor, or in the case of any other similar judicial
proceedings relative to the Company or other obligor on the Securities and
coupons, or to the creditors or property of the Company or such other obligor,
the Trustee, irrespective of whether the principal of the Securities shall then
be due and payable as expressed in the Securities or by declaration or otherwise
and irrespective of whether the Trustee shall have made any demand pursuant to
the provisions of this Section 5.02, shall be entitled and empowered, by
intervention in such proceedings or otherwise, to file and prove a claim or
claims for the whole amount of principal and any premium and interest owing and
unpaid in respect of the Securities, and, in case of any judicial proceedings,
(i) to file such proofs of claim and other papers or documents as may be
necessary or advisable in order to have the claims of the Trustee (including any
claim for the 

                                      42
<PAGE>
 
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel) and of the Securityholders allowed in such judicial
proceedings relative to the Company or any other obligor on the Securities and
coupons, its or their creditors, or its or their property, and (ii) to collect
and receive any money or other property payable or deliverable on any such
claims, and to distribute the same after the deduction of its charges and
expenses; and any receiver, assignee or trustee in bankruptcy or reorganization
is hereby authorized by each of the Securityholders 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 Securityholders, to pay to the Trustee any amount due
it for reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and its counsel and any other amounts due the Trustee under
Section 6.06. To the extent that such payment of reasonable compensation,
expenses and counsel fees out of the trust estate in any such proceedings shall
be denied for any reason, payment of the same shall be secured by a lien on, and
shall be paid out of, any and all distributions, dividends, money, securities
and other property which the holders of the Securities and coupons may be
entitled to receive in such proceedings, whether in liquidation or under any
plan of reorganization or arrangement or otherwise.

          (d)  Nothing contained in this Section 5.02 shall be deemed to
authorize the Trustee to authorize or consent to or adopt on behalf of any
Securityholder any plan of reorganization or arrangement affecting the
Securities or related coupons or the rights of any Securityholder, or to
authorize the Trustee to vote in respect of the claim of any Securityholder in
any such proceeding.

          (e)  All rights of action and of asserting claims under this
Indenture, or under any of the Securities or related coupons, may be enforced by
the Trustee without the possession of any of the Securities or coupons, or the
production thereof in any trial or other proceeding relative thereto, and any
such suit or proceeding instituted by the Trustee shall be brought in its own
name as trustee of an express trust, and any recovery of 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 the holders of the Securities and related coupons.

          SECTION 5.03.  Application of Money Collected by Trustee.  Any money
                         -----------------------------------------              
collected by the Trustee with respect to any series of Securities or related
coupons pursuant to Section 5.02 shall be applied, subject to the provisions of
Article Three, in the order following, at the date or dates 

                                      43
<PAGE>
 
fixed by the Trustee for the distribution of such money, upon presentation of
the several Securities of such series or coupons, or both, as the case may be,
and stamping thereon the payment, if only partially paid, and upon surrender
thereof if fully paid:

          FIRST:   To the payment of all amounts then due the Trustee under
     Section 6.06;

          SECOND:  In case the principal of the Outstanding Securities of that
     series shall not have become due and be unpaid, to the payment of interest
     on the Securities of that series in the order of the Maturity of the
     installments of such interest, with interest (to the extent enforceable
     under applicable law) upon the overdue installments of interest at the rate
     borne by the Securities of that series, such payments to be made ratably to
     the persons entitled thereto; and

          THIRD:   In case the principal of the Outstanding Securities of that
     series shall have become due, by declaration or otherwise, to the payment
     of the whole amount then owing and unpaid upon the Securities of that
     series for principal and any premium and interest, with interest on the
     overdue principal and any premium and (to the extent enforceable under
     applicable law) upon overdue installments of interest at the rate borne by
     the Securities of that series; and in case such money shall be insufficient
     to pay in full the whole amounts so due and unpaid upon the Securities of
     that series, then to the payment of such principal and any premium and
     interest without preference or priority of principal over interest, or of
     interest over principal or of any premium over principal or interest, or of
     principal or interest over any premium or of any installment of interest
     over any other installment of interest, or of any Security of that series
     over any other Security of that series, or of any coupon related to a
     Security of a series over any other coupon related to a Security of the
     same series, ratably to the aggregate of such principal and any premium and
     accrued and unpaid interest.

          SECTION 5.04.  Proceedings by Securityholders.  No holder of any
                         ------------------------------                     
Security of any series or any related coupon shall have any right to institute
any suit, action or proceeding in equity or at law upon or under or with respect
to this Indenture or for the appointment of a receiver or trustee, or for any
other remedy under this Indenture, unless such holder previously shall have
given to the Trustee written notice of default and of the continuance thereof,
as provided in Section 5.01, and unless also (i) the holders of not less than
25% in aggregate principal amount of the Securities of 

                                      44
<PAGE>
 
that series then Outstanding shall have made written request upon the Trustee to
institute such action, suit or proceeding in its own name as Trustee under this
Indenture and shall have offered to the Trustee such reasonable indemnity as the
Trustee may require against the costs, expenses and liabilities to be incurred
in compliance with such request, (ii) the Trustee for 60 days after its receipt
of such notice, request and offer of indemnity, shall have neglected or refused
to institute any such action, suit or proceeding and (iii) 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 that series; it being understood and intended, and
being expressly covenanted by each Person who acquires and holds a Security or
related coupon with every other such Person, that no one or more holders of
Securities shall have any right in any manner whatever by virtue of or by
availing of any provision of this Indenture to affect, disturb or prejudice the
rights of any other holder of such Securities or coupons, or to obtain or seek
to obtain priority over or preference to any other such holder, or to enforce
any right under this Indenture, except in the manner provided in this Section
5.04 and for the equal, ratable and common benefit of all holders of Securities
and coupons.

          Notwithstanding any other provision of this Indenture, however, the
right of any holder of any Security to receive payment of the principal of and
any premium and interest on such Security on or after the respective Stated
Maturities, or to institute suit for the enforcement of any such payment on or
after such respective dates against the Company, shall not be impaired or
affected without the consent of such holder.

          SECTION 5.05.  Proceedings by Trustee.  In case of an Event of
                         ----------------------                           
Default under this Indenture, the Trustee in its discretion may proceed to
protect and enforce its rights and the rights of the Securityholders by such
appropriate judicial proceedings as the Trustee shall deem most effectual to
protect and enforce any such rights, either by suit in equity or by action at
law or by proceeding in bankruptcy or otherwise, whether for the specific
enforcement of any covenant or agreement contained in this Indenture or in aid
of the exercise of any power granted in this Indenture, or to enforce any other
proper remedy or legal or equitable right vested in the Trustee by this
Indenture or by law.

          SECTION 5.06.  Remedies Cumulative and Continuing; Delay or Omission
                         -----------------------------------------------------
Not Waiver.  All rights, powers and remedies conferred upon or reserved to the
- ----------                                                                      
Trustee or to the Securityholders, to the extent permitted by law, shall be
deemed cumulative and not exclusive of any thereof or of any 

                                      45
<PAGE>
 
other rights, powers and remedies available to the Trustee or the holders of the
Securities and related coupons, now or hereafter existing, by judicial
proceedings or otherwise, to enforce the performance or observance of the
covenants and agreements contained in this Indenture; and no delay or omission
of the Trustee or of any holder of any of the Securities or related coupons to
exercise any such right, power or remedy shall impair any such right, power or
remedy, or shall be construed to be a waiver of any default or an acquiescence
in such default; and, subject to the provisions of Section 5.04, every power and
remedy conferred upon or reserved to the Trustee or to the Securityholders may
be exercised from time to time, and as often as shall be deemed expedient, by
the Trustee or by the Securityholders. The assertion of any right, power or
remedy shall not prevent the concurrent assertion of any other right, power or
remedy.

          SECTION 5.07.  Direction of Proceedings and Waiver of Defaults by
                         --------------------------------------------------
Majority of Securityholders.  (a)  The holders of a majority in aggregate
- ---------------------------                                                
principal amount of the Securities of all series affected (voting as one class)
at the time Outstanding determined in accordance with Section 7.04 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; provided, however, that (i) such direction may not be in
conflict with law or this Indenture or expose the Trustee to personal liability
or be unduly prejudicial to the holders of the Securities and related coupons
not joining in the direction, and (ii) the Trustee may take any other action
deemed proper by the Trustee that is not inconsistent with this Indenture and
such direction.

          (b)  Prior to any declaration that the principal of the Outstanding
Securities of any series is due and payable, the holders of a majority in
aggregate principal amount of the Securities of that series at the time
Outstanding on behalf of the holders of all of the Securities of that series may
waive any past default or Event of Default or Acceleration Event under this
Indenture and its consequences except a default under a covenant in this
Indenture that, pursuant to Section 9.02, cannot be modified without the consent
of each holder of a Security of the series affected thereby. Upon any such
waiver, the Company, the Trustee and the holders of the Securities of that
series and the related coupons shall be restored to their former positions and
rights under this Indenture, respectively; but no such waiver shall extend to
any subsequent or other default or Event of Default or Acceleration Event or
impair any right consequent thereon. Whenever any default or Event of Default or
Acceleration Event under this Indenture shall have been waived as permitted by
this Section 5.07, such default or Event of Default or

                                      46
<PAGE>
 
Acceleration Event, for all purposes of the Securities, the related coupons and
this Indenture, shall be deemed to have been cured and to be not continuing.

          SECTION 5.08.  Notices of Defaults.  The Trustee, within 90 days 
                         -------------------                                
after the occurrence of a default with respect to Securities of any series,
shall mail to all Securityholders of that series, at their addresses shown on
the Security Register, notice of all such defaults known to the Trustee, unless
such defaults shall have been cured or waived before the giving of such notice
(the term "default" for the purpose of this Section 5.08 being hereby defined to
mean any event which constitutes or after notice or lapse of time or both would
constitute an Event of Default); and provided that, except in the case of
default in the payment of the principal of or any premium or interest on any of
the Securities of that series or in the making of any sinking fund payment or
analogous obligation with respect to Securities of that 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 or
Responsible Officers of the Trustee in good faith determines that the
withholding of such notice is in the interest of the Securityholders of that
series.

          SECTION 5.09.  Undertaking to Pay Costs.  All parties to this
                         ------------------------                        
Indenture agree, and each holder of any Security or coupon by his acceptance
thereof shall be deemed to have agreed, that any court in its discretion may
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 an undertaking
to pay the costs of such suit and that such court in its discretion may assess
reasonable costs, including reasonable attorneys' fees, against any party
litigant; provided, however, that the provisions of this Section 5.09 shall not
apply to any suit instituted by the Trustee, to any suit instituted by any
Securityholder, or group of Securityholders, holding in the aggregate more than
10% in principal amount of the Outstanding Securities of that series, or to any
suit instituted by any Securityholder for the enforcement of the payment of the
principal of or any premium or interest on any Security on or after the
respective Stated Maturities (or, in the case of redemption or repayment, on or
after the redemption date or repayment date).

                            CONCERNING THE TRUSTEE

          SECTION 6.01.  Duties and Responsibilities of Trustee.  In case an
                         --------------------------------------               
Event of Default has occurred (which has not been cured or waived) the Trustee
shall exercise such of the rights and powers vested in it by this Indenture, and
use the same degree of care and skill in their exercise, as a prudent man would
exercise or use under the circumstances in the conduct of his own affairs.

          No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, its own willful misconduct or any action or failure to act taken or
omitted by it in bad faith, except that:

          (a)  except during the continuance of an Event of Default:

               (1)  the duties and obligations of the Trustee shall be
          determined solely by the express provisions of this Indenture, and the
          Trustee shall not be liable except for the performance of such duties
          and obligations as are specifically set forth in this Indenture, and
          no implied covenants or obligations shall be read into this Indenture
          against the Trustee; and

               (2)  in the absence of bad faith on the part of the Trustee, the
          Trustee conclusively may rely, as to the truth of the statements and
          the correctness of the opinions expressed therein, upon any
          certificates or opinions furnished to the Trustee and conforming to
          the requirements of this Indenture; but, in the case of any such
          certificates or opinions that by any provisions of this Indenture
          specifically are required to be furnished to the Trustee, the Trustee
          shall be under a duty to examine the same to determine whether or not
          they conform to the requirements of this Indenture;

          (b)  the Trustee shall not be liable for any error of judgment made in
     good faith by a Responsible Officer or Officers of the Trustee, unless it
     shall be proved that the Trustee was negligent in ascertaining the
     pertinent facts; and

          (c)  the Trustee shall not be liable with respect to any action taken
     or omitted to be taken by it in good faith in accordance with the direction
     of the holders of 

                                      48
<PAGE>
 
     not less than a majority in principal amount of the Securities of any
     series at the time Outstanding (determined as provided in Section 7.04)
     relating to the time, method and place of conducting any proceeding for any
     remedy available to the Trustee, or exercising any trust or power conferred
     upon the Trustee, under this Indenture.

          None of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of
its rights or powers, if it shall have reasonable grounds for believing that the
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

          Whether or not expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of this Section
6.01.

          The provisions of this Section 6.01 are in furtherance of and subject
to Sections 315 and 316 of the Trust Indenture Act.

subject to the provisions of Section 6.01:

          (a)  the Trustee may rely and shall be protected in acting upon any
     resolution, certificate, statement, instrument, opinion, report, notice,
     request, consent, order, bond, debenture or other paper or document
     believed by it to be genuine and to have been signed or presented by the
     proper party or parties;

          (b)  any request, direction, order or demand of the Company mentioned
     herein shall be sufficiently evidenced by an Officers' Certificate (unless
     other evidence in respect thereof be herein specifically prescribed); and
     any resolution of the Board of Directors may be evidenced to the Trustee by
     a copy thereof certified by the Secretary or an Assistant Secretary of the
     Company;

          (c)  the Trustee may consult with counsel and any Opinion of Counsel
     shall be full and complete authorization and protection in respect of any
     action taken or omitted by it under this Indenture in good faith and in
     accordance with such Opinion of Counsel;

                                      49
<PAGE>
 
          (d)  the Trustee shall be under no obligation to exercise any of the
     rights or powers vested in it by this Indenture at the request, order or
     direction of any of the Securityholders, pursuant to the provisions of this
     Indenture, unless such Securityholders shall have offered to the Trustee
     reasonable security or indemnity against the costs, expenses and
     liabilities that may be incurred therein or thereby;

          (e)  the Trustee shall not be liable for any action taken or omitted
     by it in good faith and believed by it to be authorized or within the
     discretion or rights or powers conferred upon it by this Indenture;

          (f)  the Trustee shall not be bound to make any investigation into the
     facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, report, notice, request, consent, order, approval,
     bond, debenture, coupon or other paper or document, but the Trustee, in its
     discretion, may make such further inquiry or investigation into such facts
     or matters as it may see fit, and, if the Trustee shall determine to make
     such further inquiry or investigation, it shall be entitled to examine the
     books and records of the Company to the extent reasonably necessary to
     verify such facts or matters; and

          (g)  the Trustee may execute any of the trusts or powers under this
     Indenture or perform any duties under this Indenture either directly or by
     or through agents or attorneys and the Trustee shall not be responsible for
     any misconduct or negligence on the part of any agent or attorney appointed
     by it with due care under this Indenture.

          SECTION 6.03.  No Responsibility for Recitals, etc.  The recitals
                         -----------------------------------                 
contained in this Indenture and in the Securities (except in the Trustee's
certificate of authentication) and in any coupons shall be taken as the
statements of the Company, and the Trustee assumes no responsibility for the
correctness of the same.  The Trustee makes no representations as to the
validity or sufficiency of this Indenture or of the Securities or the coupons.
The Trustee shall not be accountable for the use or application by the Company
of any Securities or the proceeds of any Securities authenticated and delivered
by the Trustee.

          SECTION 6.04.  Trustee, Paying Agents or Registrar May Own Securities.
                         ------------------------------------------------------
Subject to the applicable provisions of the Trust Indenture Act, the Trustee or
any Paying Agent or Security registrar, in its individual or any other capacity,
may become the owner or pledgee of Securities with the same 

                                      50
<PAGE>
 
rights it would have if it were not Trustee, Paying Agent or Security registrar.

          SECTION 6.05.  Money to Be Held in Trust.  Subject to the provisions
                         -------------------------                              
of Section 14.03 and Section 14.04, all money received by the Trustee, until
used or applied as herein provided, shall be held in trust for the purposes for
which it was received.  Money held by the Trustee need not be segregated from
other funds except as provided by law.  The Trustee shall be under no liability
for interest on any money received by it under this Indenture, except as the
Company and the Trustee otherwise may agree.

          SECTION 6.06.  Compensation and Expenses of Trustee.  The Company
                         ------------------------------------

compensation of a trustee of an express trust), and the Company will pay or
reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
any of the provisions of this Indenture (including the reasonable compensation
and the reasonable expenses and disbursements of its counsel and of all persons
not regularly in its employ) except any such expense, disbursement or advance as
may be attributable to its negligence, bad faith or willful misconduct.  The
Company also covenants to indemnify the Trustee for, and to hold it harmless
against, any loss, liability or expense incurred without negligence, bad faith
or willful misconduct on the part of the Trustee and arising out of or in
connection with the acceptance or administration of this trust, including the
reasonable costs and expenses of defending itself against any claim of liability
in connection with the exercise or performance of any of its powers under this
Indenture.  The obligations of the Company under this Section 6.06 shall

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

proved or established prior to taking or omitting any action under this
Indenture, such matter (unless other evidence in respect thereof be herein

misconduct on the part of the Trustee, may be deemed to be conclusively proved
and established by an Officers' Certificate delivered to the Trustee, and such
Officers' Certificate, in the absence of negligence, bad faith or willful
misconduct on the part of the Trustee, shall be full warrant to the Trustee for
any action 

                                      51
<PAGE>
 
taken or omitted by it under the provisions of this Indenture upon the faith of
such Officers' Certificate.

          SECTION 6.08.  Eligibility of Trustee.  The Trustee under this
                         ----------------------                           
Indenture shall at all times be a corporation organized and doing business under
the laws of the United States or any State thereof or of the District of
Columbia (or a corporation or other person permitted to act as Trustee by the
Commission) authorized under such laws to exercise corporate trust powers,
having a combined capital and surplus of at least $50,000,000 and subject to
supervision or examination by Federal, State or District of Columbia authority.
If such corporation publishes reports of condition at least annually, pursuant
to law or to the requirements of the aforesaid supervising or examining
authority, then for the purposes of this Section 6.08, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published.  In
case at any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section 6.08, the Trustee shall resign immediately in the
manner and with the effect specified in Section 6.09.  Neither the Company nor
any person directly or indirectly controlling, controlled by, or under common
control with the Company shall serve as Trustee under this Indenture.

          SECTION 6.09.  Resignation or Removal of Trustee.  (a)  The Trustee
                         ---------------------------------                     
may resign at any time by giving written notice of such resignation to the
Company, by mailing notice of such resignation to the holders of Registered
Securities at their addresses as they shall appear on the Security Register,
and, if any Bearer Securities are Outstanding, by publishing notice of such
resignation in a newspaper of general circulation, in each place of payment for
such Bearer Securities, customarily published at least once a day for at least
five days in each calendar week.

          (b)  In case at any time any of the following shall occur:

               (1)  the Trustee shall fail to comply with the provisions of
     Section 310(b) of the Trust Indenture Act after written request therefor by
     the Company or by any Securityholder who has been a bona fide holder of a
     Security or Securities for at least six months, or

               (2)  the Trustee shall cease to be eligible in accordance with
     the provisions of Section 6.08 and shall fail to resign after written
     request therefor by the Company or by any such Securityholder, or

                                      52
<PAGE>
 
               (3)  the Trustee shall become incapable of acting, or shall be
     adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its
     property shall be appointed or a 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, the Company may remove the Trustee by written
instrument, executed by Company Order authorized by the Board of Directors, one
copy of which instrument shall be delivered to the Trustee so removed and one
copy to the successor Trustee (with written notice of such removal mailed to the
holders of Registered Securities at their address as they shall appear on the
Security Register, and, if any Bearer Securities are Outstanding, by publishing
notice of such resignation in a newspaper of general circulation, in each place
of payment for such Bearer Securities, customarily published at least once a day
for at least five days in each calendar week), or, subject to the provisions of
Section 5.09, any Securityholder who has been a bona fide holder of a Security
or Securities for at least six months, on behalf of himself and all others
similarly situated, may petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee.

          (c)  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, the
Company promptly shall appoint a successor Trustee by a Company Order authorized
by the Board of Directors, one copy of which instrument shall be delivered to
the retiring Trustee and one copy to the successor Trustee.  If, within one year
after such resignation, removal or incapability or the occurrence of such
vacancy, a successor Trustee shall be appointed by the holders of a majority in
principal amount of the Securities (voting as a single class) at the time
Outstanding by instrument or instruments delivered to the Company and the
retiring Trustee, the successor Trustee so appointed, forthwith upon its
acceptance of such appointment, shall become the successor Trustee and supersede
the successor Trustee appointed by the Company.  If no successor Trustee shall
have been so appointed by the Company or the Securityholders and accepted
appointment in the manner provided in Section 6.10 within 60 days after notice
of the resignation or removal of the Trustee is mailed to the Securityholders,
the resigning Trustee may petition any court of competent jurisdiction for the
appointment of a successor Trustee, or any Securityholder who has been a bona
fide holder of a Security or Securities for at least six months, subject to the
provisions of Section 5.09, on behalf of himself and all others similarly
situated, may petition any 

                                      53
<PAGE>
 
court of competent jurisdiction for the appointment of a successor Trustee.

          (d)  The holders of a majority in aggregate principal amount of the
Securities (voting as a single class) at the time Outstanding at any time, upon
notice to the Trustee, may remove the Trustee.

          (e)  Any removal of the Trustee and appointment of a successor Trustee
pursuant to any of the provisions of this Section 6.09 shall become effective
upon acceptance of appointment by the successor Trustee as provided in Section
6.10.  Any resignation of the Trustee shall become effective only upon the
appointment of a successor Trustee and upon the acceptance of appointment by the
successor Trustee as provided in Section 6.10.

          SECTION 6.10.  Acceptance by Successor Trustee.  Any successor
                         -------------------------------                  
Trustee appointed as provided in Section 6.09 shall execute, acknowledge and
deliver to the Company and to its predecessor Trustee an instrument accepting
such appointment under this Indenture, and thereupon the resignation or removal
of the predecessor Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, duties and obligations of its predecessor under this Indenture,
with like effect as if originally named as Trustee in this Indenture; but,
nevertheless, on the written request of the Company or of the successor Trustee,
the Trustee ceasing to act, upon payment of any amounts then due it pursuant to
the provisions of Section 6.06, shall execute and deliver an instrument
transferring to such successor Trustee all the rights and powers of the Trustee
so ceasing to act and shall transfer, assign and deliver to such successor all
property and money held by such predecessor Trustee under this Indenture.  Upon
request of any such successor Trustee, the Company shall execute any and all
instruments in writing for more fully and certainly vesting in and confirming to
such successor Trustee all such rights and powers.  Any Trustee ceasing to act
nevertheless shall retain a lien upon all property or funds held or collected by
such Trustee to secure any amounts then due it pursuant to the provisions of
Section 6.06.

          No successor Trustee shall accept appointment as provided in this
Section 6.10 unless at the time of such acceptance such successor Trustee shall
be qualified under the provisions of Section 310(b) of the Trust Indenture Act
and eligible under the provisions of Section 6.08.

          Upon acceptance of appointment by a successor Trustee as provided in
this Section 6.10, the Company shall 

                                      54
<PAGE>
 
mail notice of the succession of such Trustee under this Indenture to the
holders of Registered Securities at their addresses as they shall appear on the
Security Register, and, if any Bearer Securities are Outstanding, by publishing
notice of such resignation in a newspaper of general circulation, in each place
of payment for such Bearer Securities, customarily published at least once a day
for at least five days in each calendar week. If the Company fails to mail such
notice within ten days after acceptance of appointment by the successor Trustee,
the successor Trustee shall cause such notice to be mailed and, if necessary,
published at the expense of the Company.

          SECTION 6.11.  Succession by Merger, etc.  Any corporation into which 
                         -------------------------                         
the Trustee may be merged or converted or with which it may be consolidated, or
any corporation resulting from any merger, conversion or consolidation to which
the Trustee shall be a party, or any corporation succeeding to all or
substantially all the corporate trust business of the Trustee, shall be the
successor Trustee under this Indenture without the execution or filing of any
paper or any further act on the part of any of the parties to this Indenture
provided such corporation shall be qualified under the provisions of Section
310(b) of the Trust Indenture Act and eligible under the provisions of Section
6.08.

          In case at the time such successor Trustee shall succeed to the trusts
created by this Indenture any of the Securities shall have been authenticated
but not delivered, any such successor Trustee may adopt the certificate of
authentication of any predecessor Trustee, and deliver such Securities so
authenticated; and in case at that time any of the Securities shall not have
been authenticated, any successor Trustee may authenticate such Securities
either in the name of any predecessor Trustee under this Indenture or in the
name of the successor Trustee; and in all such cases such certificates shall
have the full force which it is anywhere in the Securities or in this Indenture
provided that the certificate of the Trustee shall have; provided, however, that
the right to adopt the certificate of authentication of any predecessor Trustee
or authenticate Securities in the name of any predecessor Trustee shall apply
only to its successor or successors by merger, conversion or consolidation.

                         -------------------------                     
it is provided that the holders of a specified percentage in aggregate principal
amount of the Securities of any or all series may take any action (including

                                      55
<PAGE>
 
the making of any demand or request, the giving of any notice, consent or waiver
or the taking of any such other action), the fact that at the time of taking any
such action the holders of such specified percentage have joined in such action
may be evidenced (i) by any instrument or any number of instruments of similar
tenor executed by Securityholders in person or by agent or proxy appointed in
writing, (ii) by the record of the holders of Securities voting in favor of such
action at any meeting of Securityholders duly called and held in accordance with
the provisions of this Article Seven or (iii) by a combination of such
instrument or instruments and any such record of such a meeting of
Securityholders. The Company may set a record date for purposes of determining
the identity of holders entitled to vote or consent to any action by vote or
consent authorized or permitted under this Indenture, which record date shall be
the later of ten days prior to the first solicitation of such consent or the
date of the most recent list of holders furnished to the Trustee pursuant to the
provisions of Section 312(a) of the Trust Indenture Act prior to such
solicitation. If a record date is fixed, those persons who were holders of
Securities at such record date (or their duly designated proxies), and only
those persons, shall be entitled to take such action by vote or consents or to
revoke any vote or consent previously given, whether or not such persons
continue to be holders after such record date. No such vote or consent shall be
valid or effective if such vote occurs or such consent is obtained more than 120
days after such record date.

          SECTION 7.02.  Proof of Execution by Securityholders.  (a)  Subject  
                         -------------------------------------                 
to the provisions of Sections 6.01, 6.02 and 8.05, proof of the execution of any
instrument by a Securityholder or his agent or proxy shall be sufficient if made
in accordance with such reasonable rules and regulations as may be prescribed by
the Trustee or in such manner as shall be satisfactory to the Trustee.

          (b)  The ownership of Registered Securities of any series shall be
proved by the Security Register or by a certificate of the Security registrar of
such series.

          (c)  The principal amount and serial numbers of Bearer Securities held
by any Person, and the date 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, wherever situated, if such
certificate shall be deemed by 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 in the amount and with the serial numbers
therein described; or such facts may be proved by the certificate or affidavit
of the Person holding such Bearer 

                                      56
<PAGE>
 
Securities, if such certificate or affidavit is deemed by the Trustee to be
satisfactory. The Trustee and the Company may assume that such ownership of any
Bearer Security continues until (i) another certificate or affidavit bearing a
later date issued in respect of the same Bearer Security is produced, (ii) such
Bearer Security is produced to the Trustee by some other Person, (iii) such
Bearer Security is surrendered in exchange for a Registered Security or (iv)
such Bearer Security is no longer Outstanding. The fact and date of execution of
any such instrument or writing, the authority of the Person executing the same
and the principal amount and serial numbers of Bearer Securities held by the
Person so executing such instrument or writing and the date of holding the same
may also be proved in any other manner which the Trustee deems sufficient; and
the Trustee may in any instance require further proof with respect to any of the
matters referred to in this Section 7.02(c).

          (d)  The record of any Securityholders' meeting shall be proved in the
manner provided in Section 8.07.

          SECTION 7.03.  Who Are Deemed Absolute Owners.  Prior to due
                         ------------------------------                 
presentation of a Registered Security for registration of transfer, the Company,
the Trustee, any Paying Agent and any Security registrar may treat the Person in
whose name such Registered Security is registered as owner of such Registered
Security for the purpose of receiving payment of principal of and any premium

other purposes whatsoever, whether or not such Registered Security is overdue
and notwithstanding any notation of ownership or other writing on such
Registered Security made by anyone other than the Company or any Security
registrar, and neither the Company, the Trustee, any Paying Agent nor any
Security registrar shall be affected by any notice to the contrary.  All such
payments so made to any such holder as shown in the Security Register, or upon
his order, shall be valid, and, to the extent of the sum or sums so paid,
effectual to satisfy and discharge the liability for money payable upon any such

whether or not such Bearer Security or coupon is overdue, and neither the
Company, the Trustee, any Paying Agent nor any Security registrar shall be

whether the holders of the requisite aggregate principal amount of Securities
have concurred in any direction, consent, waiver or other action under this
Indenture, Securities that are owned by the Company or any other obligor on the
Securities or by any person directly or indirectly controlling or controlled by
or under direct or indirect common control with the Company or any other obligor
on the Securities shall be disregarded and deemed not to be Outstanding for the
purpose of any such determination; provided, however, that for the purposes of
determining whether the Trustee shall be protected in relying on any such
direction, consent, waiver or other action, only Securities that the Trustee
knows are so owned shall be so disregarded.

          SECTION 7.05.  Revocation of Consents; Future Holders Bound.  At any

the holders of which have consented to such action, by filing written notice
with the Trustee at the principal office of the Trustee and upon proof of
holding as provided in Section 7.02, may revoke such action so far as concerns
such Security.  Except as provided in this Section 7.05, any such action taken
by the holder of any Security shall be conclusive and binding upon such holder
and upon all future holders and owners of such Security, irrespective of whether
or not any notation in regard thereto is made upon such Security or any Security
issued in exchange or substitution for such Security.

into such supplemental indenture.

          It shall not be necessary for the consent of the Securityholders under
this Section 9.02 to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such consent shall approve the
substance thereof.

                           REDEMPTION OF SECURITIES

          SECTION 11.01.  Applicability of Article.  Securities of any series
                          ------------------------                             
that are redeemable before their Stated Maturity shall be redeemable only in
accordance with their terms and (except as otherwise specified as contemplated
by Section 2.01 for Securities of any series) in accordance with this Article
Eleven, to the extent Article Three does not prohibit such a redemption.

          SECTION 11.02.  Election to Redeem; Notice to Trustee.  The election
                          -------------------------------------                 
of the Company to redeem any Securities shall be evidenced by a Company Order.
In case of any redemption at the election of the Company of less than all the
Securities of any series, the Company, at least 60 days prior to the Redemption
Date fixed by the Company (unless a shorter notice shall be satisfactory to the
Trustee), shall notify the Trustee of such Redemption Date, of the tenor and
terms of the Securities of such series to be redeemed and of the principal
amount of such Securities to be redeemed.  In the case of any redemption of
Securities prior to the expiration of any restriction on such redemption
provided in the terms of such Securities or elsewhere in this Indenture, the
Company shall furnish the Trustee with an Officers' Certificate evidencing
compliance with such restriction.

          SECTION 11.03.  Selection by Trustee of Securities to Be Redeemed.
                          -------------------------------------------------    
If less than all the Securities of any series of like tenor and terms specified
by the Company are to be redeemed, the particular Securities to be redeemed
shall be selected not more than 60 days prior to the Redemption Date by the
Trustee, from the Outstanding Securities of such series and of such tenor and
terms 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 (equal to the minimum authorized denominations for such Securities
or any integral multiple thereof) of the principal amount of such Registered
Securities or such Bearer Securities or a denomination larger than the minimum
authorized denomination for such Registered Securities or such Bearer
Securities.

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

          For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any 

                                      68
<PAGE>
 
Securities redeemed or to be redeemed only in part, to the portion of the

          SECTION 11.04.  Notice of Redemption.  Notice of redemption shall be
                          --------------------                                  
given in the manner provided in Section 8.02 not fewer than 30 or more than 60

               (1)  the Redemption Date;

               (2)  the Redemption Price;

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

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

               (5)  the Place or Places of Payment where such Securities,
     together in the case of Bearer Securities with all coupons, if any,
     appertaining thereto maturing after the Redemption Date, are to be
     surrendered for payment of the Redemption Price;

               (6)  that Bearer Securities may be surrendered for payment only
     at such place or places that are outside the United States, except as
     provided in Section 4.02; and

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

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

          SECTION 11.05.  Deposit of Redemption Price.  On or prior to any
                          ---------------------------                       
Redemption Date, the Company shall deposit with the Trustee or with a Paying
Agent (or, if the Company is acting as its own Paying Agent, segregate and hold
in trust as provided in Section 4.04(b)) an amount of money sufficient to pay
the Redemption Price of, and (except if the Redemption Date shall be the same
date as the Stated Maturity of an installment of interest thereon) accrued
interest on, all the 

                                      69
<PAGE>
 
Securities that are to be redeemed on that date; provided, however, that
deposits with respect to Bearer Securities shall be made with a Paying Agent or
Paying Agents located outside the United States except as otherwise provided in
Section 4.02, unless otherwise specified as contemplated by Section 2.01.

          SECTION 11.06.  Securities Payable on Redemption Date.  Notice of
                          -------------------------------------              
redemption having been given as aforesaid, the Securities so to be redeemed
shall become due and payable, on the Redemption Date, 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, such Security shall be paid by the
Company at the Redemption Price, together with accrued interest to the
Redemption Date; provided, however, that:  (i) 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 4.02); and (ii) installments of interest whose
Stated Maturity is on or prior to the Redemption Date shall be payable to the
holders of such Securities, or one or more Predecessor Securities, registered as
such at the close of business on the relevant record date for the payment of
such interest according to the terms of such Securities.

          If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant coupons maturing after the Redemption Date, such
Bearer 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
is furnished to them such security or indemnity as they may require to hold each
of them and any Paying Agent harmless.  If thereafter the holder of such Bearer
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 on
account of such coupon without interest thereon; provided, however, that
interest represented by coupons shall be payable only upon presentation and
surrender of those coupons at an office or agency located outside of the United
States except as otherwise provided in Section 4.02.

          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 or related coupon.

          SECTION 11.07.  Registered Securities Redeemed in Part.  Any
                          --------------------------------------        
Registered Security that is to be redeemed only in part shall be surrendered at
a Place of Payment therefor (with, if the Company or the Trustee so requires,
due endorsement by, or a written instrument of transfer in form satisfactory to
the Company and the Trustee duly executed by, the holder thereof or his attorney
duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and deliver to the holder of such Security without service
charge, a new Registered Security or new Registered Securities of the same
series and of like tenor and terms, 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.

in each case in satisfaction of all or any part of any sinking fund payment with
respect to the Securities of such series required to be made pursuant to the

sinking fund, and the amount of such sinking fund payment shall be reduced
accordingly.

payment date in the manner specified in Section 11.03 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 11.04. Such notice having been duly given, the

     Re:  Registration Statement on Form S-3 with respect to $1 Billion
          Principal Amount of Debt Securities

Dear Ladies and Gentlemen:

     We have acted as counsel to Southern National Corporation (the "Company")
in connection with the registration by the Company of up to $1 billion principal
amount of senior or subordinated Debt Securities, issuable pursuant to the
Senior Indenture or the Subordinated Indenture as set forth in the registration
statement on Form S-3 (the "Registration Statement") that is being filed on the
date hereof by the Company with the Securities and Exchange Commission pursuant
to the Securities Act of 1933, as amended. This opinion letter is Exhibit 5 to
the Registration Statement. All capitalized terms not otherwise defined herein
shall have the meanings given to them in the Registration Statement.

     The Debt Securities are to be issued, separately or together, in accordance
with the terms of the Indentures in one or more series and are to be sold from
time to time as set forth in the Registration Statement, the prospectuses
contained therein (each, a "Prospectus") and any amendments or supplements
thereto.

     In connection with the foregoing, we have examined such records, documents
and proceedings as we have deemed relevant as a basis for the opinion expressed
herein, and we have relied upon an officer's certificate as to certain factual
matters.

     Based on the foregoing, we are of the opinion that when (1) the
Registration Statement shall have been declared effective by order of the
Securities and Exchange Commission, (2) the terms of any class or series of the
Debt Securities have been authorized by appropriate corporate action of the
Company and (3) the Debt Securities have been issued and sold in accordance with
the Senior Indenture or Subordinated Indenture, as the case may be, and upon the
terms and conditions set forth in the Registration Statement, the applicable
Prospectus and the applicable supplement to such Prospectus, then the Debt
Securities will be validly authorized and issued and binding obligations of the
Company.

     We hereby consent to be named in the Registration Statement and in each of
the Prospectuses as attorneys who passed upon the legality of the Securities and
to the filing of a copy of this opinion as Exhibit 5 to the Registration
Statement.

                                     Very truly yours,

                                     WOMBLE CARLYLE SANDRIDGE & RICE,
