To the Representative named in Schedule I hereto of the
Underwriters named in Schedule II hereto

Dear Sirs:

                  First Union Corporation ("First Union"), a North Carolina
corporation, proposes to sell to the underwriters named in Schedule II hereto
(the "Underwriters"), for whom you are acting as Representative (the
"Representative"), its designated debt securities named in Schedule I hereto
(the "Securities"), in the aggregate principal amount set forth in such Schedule
I. The Securities will be issued under the indenture referenced in Schedule I
hereto (the "Indenture"), between First Union and the trustee named in Schedule
I (the "Trustee").

                  1. Representations and Warranties. First Union represents and
warrants to, and agrees with, each Underwriter that:

                  (a) The registration statement (File No. 33- 61941) on Form
         S-3, and the registration statement (File No. 333-34151) on Form S-3
         (the "registration statements"), including a prospectus which, as
         supplemented, shall be used in connection with the sale of the
         Securities, have been filed with the Securities and Exchange Commission
         (the "Commission"), in the forms heretofore delivered to the
         Representative. Each registration statement, as it may have been
         amended prior to the date of this Agreement, has become effective under
         the Securities Act of 1933, as amended (the "Act"). (The registration
         statements, as amended








         to the date of this Agreement, are hereinafter collectively referred to
         as the "Registration Statement"; such prospectus (which shall be in
         the form in which it has been most recently filed, or transmitted for
         filing, with the Commission on or before the date of this Agreement, as
         the same is proposed to be added to or changed), as supplemented by a
         prospectus supplement relating to the Securities, filed or transmitted
         for filing with the Commission pursuant to Rule 424 under the Act and
         used in connection with the sale of the Securities, is hereinafter
         referred to as the "Prospectus"; and such prospectus supplement is
         hereinafter referred to as the "Prospectus Supplement". Any reference
         herein to the Registration Statement, a preliminary prospectus or the
         Prospectus shall be deemed to refer to and include the documents
         incorporated by reference therein pursuant to Item 12 of Form S-3
         which were filed under the Securities Exchange Act of 1934, as amended
         (the "Exchange Act"), on or before the date of this Agreement, and any
         reference herein to the terms "amend", "amendment" or "supplement" with
         respect to the Registration Statement or the Prospectus shall be deemed
         to refer to and include the filing of any document under the Exchange
         Act deemed to be incorporated therein by reference after the date of
         this Agreement.)

                  (b) The Registration Statement, at the time it became
         effective, and any amendments thereof filed prior to the date hereof,
         as of their respective effective dates, conformed in all material
         respects to the requirements of the Act, the Trust Indenture Act of
         1939, as amended (the "Trust Indenture Act"), and the respective rules
         and regulations of the Commission thereunder; the Registration
         Statement and the Prospectus, as of the date of the Prospectus
         Supplement, and any amendments thereof and supplements thereto, as of

         respects to the requirements of the Act, the Trust Indenture Act and
         the respective rules and regulations of the Commission thereunder, and
         no such document, as of such respective dates and, in the case of the
         Prospectus and any amendments thereof or supplements thereto, as of the
         Closing Date (as hereinafter defined), included or will include any
         untrue statement of a material fact or omitted or will omit to state
         any material fact required to be stated

         Agreement") and the calculation agency agreement referenced in Schedule
         I hereto (the "Calculation Agency Agreement") have each been duly
         authorized and, at the Closing Date, will each constitute a valid and
         legally binding instrument, enforceable in accordance with its terms,

not jointly, to purchase from First Union, at the purchase price set forth in

                  3. Delivery and Payment. Delivery of and payment for the

                  4. Offering by Underwriters. It is understood that the several

Prospectus.

                  5. Agreements. First Union agrees with the several
Underwriters that:

                  (a) First Union will cause the Prospectus to be filed, or
         transmitted for filing, with the Commission pursuant to Rule 424 under
         the Act and will promptly advise the Representative when the Prospectus
         has been so filed or transmitted for filing, and, prior to the
         termination of the offering of the Securities to which such Prospectus
         relates, also will promptly advise the Representative (i) when any
         amendment to the Registration Statement has become effective or any
         further supplement to the Prospectus has been so filed or transmitted
         for filing, (ii) of any request by the Commission for any amendment of
         the Registration Statement or the Prospectus or for any additional
         information, (iii) of the issuance by the Commission of

                                        5







         any stop order suspending the effectiveness of the Registration
         Statement or the institution or threatening of any proceeding for that
         purpose, and (iv) of the receipt by First Union of any notification
         with respect to the suspension of the qualification of the Securities
         for sale in any jurisdiction or the initiation or threatening of any
         proceeding for such purpose. First Union will use its reasonable best
         efforts to prevent the issuance of any such stop order and, if issued,
         to obtain as soon as reasonably possible the withdrawal thereof. For so
         long as a prospectus relating to the Securities is required to be
         delivered under the Act, First Union will not file or transmit for
         filing any amendment to the Registration Statement or supplement to the
         Prospectus which relates to the Securities unless First Union has
         furnished you or counsel for the Underwriters a copy for your review
         prior to filing or transmission for filing.

                  (b) If, at any time when a prospectus relating to the
         Securities is required to be delivered under the Act, any event occurs
         as a result of which the Prospectus as then amended or supplemented
         would include any untrue statement of a material fact or omit to state
         any material fact necessary to make the statements therein in the light
         of the circumstances under which they were made not misleading, or if
         it shall be necessary to amend or supplement the Prospectus in
         connection with the sale of the Securities to comply with the Act or
         the rules and regulations of the Commission thereunder, promptly after
         becoming aware thereof, First Union will notify the Representative or
         counsel for the Underwriters and, upon either one's reasonable request,
         prepare and file or transmit for filing with the Commission an
         amendment or supplement which will correct such statement or omission
         or effect such compliance.

                  (c) First Union will make generally available to its security
         holders and to the Representative as soon as practicable, but not later
         than 45 days after the end of the 12-month period beginning at the end
         of the fiscal quarter of First Union during which the filing, or
         transmission for filing, of the Prospectus pursuant to Rule 424 under
         the Act occurs (except not later than 90 days after the end of such
         period if such quarter is the last fiscal quarter), an earnings
         statement (which

                                        6







         need not be audited) of First Union and its subsidiaries, covering
         such 12-month period, which will satisfy the provisions of Section
         11(a) of the Act.

                  (d) First Union will use its best efforts to furnish in New
         York City to each of the Underwriters prior to 10:00 a.m., New York
         City time, on the New York business day next succeeding the date of
         this Agreement and from time to time, as many copies of the Prospectus,
         each related preliminary prospectus supplement and all amendments of
         and supplements to such documents as may be reasonably requested.

                  (e) First Union will pay all expenses incident to the
         performance of its obligations under this Agreement, and will pay the
         expenses of printing and filing all documents relating to the offering
         and mailing and delivering such to Underwriters and dealers, any filing
         fee incident to any required review by the National Association of
         Securities Dealers, Inc. of the terms of the sale of the Securities,
         all expenses in connection with the qualification of the Securities for
         offering and sale under state securities laws (including the fees and
         disbursements of counsel to the Underwriters in connection with such
         qualification and the preparation of the Blue Sky and legal investment
         surveys), any taxes payable in connection with the sale and delivery of
         the Securities by First Union to the Underwriters, and any fees charged
         for rating the Securities.

                  (f) First Union will use its reasonable best efforts to
         arrange for the qualification of the Securities for sale under the laws
         of such jurisdictions as the Representative may designate and to
         maintain such qualifications in effect so long as required for the
         distribution of the Securities; provided that First Union shall not be
         required to qualify to do business in any jurisdiction where it is not
         now qualified or to take any action which would subject it to general
         or unlimited service of process in any jurisdiction where it is not now
         so subject.

                  (g) During the period beginning from the date of this
         Agreement and continuing until the Closing Date or such longer period
         as may be agreed to by First Union and set forth in Schedule I hereto
         relating to the Securities, First Union will not offer, sell, contract

                                        7







         to sell or otherwise dispose of any of its debt securities which mature
         more than one year after the Closing Date and which are substantially
         similar to the Securities without the prior written consent of the
         Representative.

                  6. Conditions to the Obligations of the Underwriters. The
obligations of the Underwriters to purchase the Securities shall be subject to
the accuracy in all material respects of the representations and warranties on
the part of First Union contained herein as of the date hereof and the Closing
Date, to the accuracy in all material respects of the statements of First Union
made in any certificates pursuant to the provisions hereof, to the performance
in all material respects by First Union of its obligations hereunder and to the
following additional conditions:

         threatened as of the Closing Date; and all requests for additional
         information on the part of the Commission shall have been complied
         with.

                  (b) First Union shall have furnished to the Representative a
         certificate, dated the Closing Date, of First Union, signed by the
         principal financial or accounting officer of First Union, to the effect
         that, to the best of his knowledge after reasonable investigation:

                           (i) The representations and warranties of First Union
                  in this Agreement are true and correct in all material
                  respects on and as of the Closing Date with the same effect as
                  if made on the Closing Date and First Union has complied with
                  all the agreements and satisfied all the conditions on its
                  part to be performed or satisfied at or prior to the Closing
                  Date, in all material respects;

                      (ii) No stop order suspending the effectiveness of the
                  Registration Statement has been issued and no proceedings for

                  statements included in the Prospectus, there has been no
                  material adverse change in the financial position, results of
                  operations, cash flows or prospects relating thereto of First
                  Union and its subsidiaries consolidated, except as set forth
                  in or contemplated by the Prospectus; and

                      (iv) Since the date of this Agreement, (A) no downgrading
                  has occurred in the rating accorded First Union's unsecured

                  Union Investors, Inc. as applicable, will not constitute a
                  breach of or default under, the corporate charter or by-laws
                  of First Union, or any material agreement, indenture or other
                  instrument relating to indebtedness for money borrowed known
                  to such counsel to which First Union is a party, or, to the
                  best of such counsel's knowledge, any law, order, rule,
                  regulation or decree of any court, governmental agency or
                  authority located in the United States having jurisdiction
                  over First Union or any property of First Union, which breach
                  or default would be reasonably likely to have a material
                  adverse effect on First Union and its subsidiaries taken as a
                  whole; and no consent, authorization or order of, or filing or
                  registration with, any court or governmental agency is
                  required for the execution, delivery and performance of this
                  Agreement, the Indenture, the Option Agreement,

                                       10







                  the Calculation Agency Agreement or the Securities by First
                  Union, First Union National Bank and First Union Investors,
                  Inc., as applicable, except such as may be required under
                  applicable state securities or "blue sky" laws or as have been
                  duly made or obtained;

                           (v) The Registration Statement has become effective
                  under the Act, and, to the best of the knowledge of such
                  counsel, no stop order suspending the effectiveness of the
                  Registration Statement has been issued and no proceedings for
                  that purpose have been instituted or are pending or threatened
                  under the Act, and each part of the Registration Statement,
                  when such part became effective, any amendments thereof filed
                  prior to the date of this Agreement, as of their respective
                  effective dates, and the Registration Statement and the
                  Prospectus, as of the date of the Prospectus Supplement, and
                  each amendment thereof or supplement thereto, as of their
                  respective effective or issue dates, appeared on their face to
                  be appropriately responsive in all material respects to the
                  requirements of the Act, the Trust Indenture Act and the
                  respective rules and regulations of the Commission
                  thereunder; such counsel has no reason to believe that any
                  part of the Registration Statement, when such part became
                  effective, contained any untrue statement of a material fact
                  or omitted to state any material fact required to be stated
                  therein or necessary to make the statements therein not
                  misleading, or that the Prospectus, as of the date of the
                  Prospectus Supplement, or any amendments thereof or
                  supplements thereto, as of their respective effective or issue
                  dates, contained any untrue statement of a material fact or
                  omitted to state any material fact necessary to make the
                  statements therein, in the light of the circumstances under
                  which they were made, not misleading, or that, as of the
                  Closing Date, either the Prospectus or any further amendment
                  or supplement thereto made by the Company prior to the Closing
                  Date contained any untrue statement of a material fact or
                  omitted to state any material fact necessary to make the
                  statements therein, in the light of the circumstances under
                  which they were made, not

                                       11







                  misleading; it being understood that such counsel need express
                  no opinion as to the Statement of Eligibility (Form T-1) under
                  the Trust Indenture Act of the Trustee, as to the financial
                  statements or other financial data contained in any part of
                  the Registration Statement or the Prospectus, as to any
                  statements or omissions made in reliance upon or in conformity
                  with information furnished in writing to First Union by or on
                  behalf of an Underwriter for use therein; and

                           (vi)     First Union Investors, Inc. is not an
                  "investment company" within the meaning of the
                  Investment Company Act of 1940.

                  As to those matters which relate to the Trustee, such counsel
         may rely upon the certificate or certificates of such Trustee, and as
         to matters governed by New York law, upon the opinion of Sullivan &
         Cromwell.

                  (d) The Representative shall have received from Sullivan &
         Cromwell, counsel for the Underwriters, such opinion or opinions, dated
         the Closing Date, with respect to such matters as the Representative
         may reasonably require.

                  As to matters governed by North Carolina law,
         Sullivan & Cromwell may rely upon the opinion of
         Marion A. Cowell, Jr. delivered pursuant to
         Section 6(c).

                  (e) KPMG Peat Marwick LLP, as independent accountants of First
         Union, shall have furnished to the Representative a letter, dated as of
         the Closing Date, to the effect set forth in Schedule III hereto. Ernst
         & Young, LLP, as independent accountants of CoreStates Financial Corp,
         shall have furnished to the Representative a letter, dated as of the
         Closing Date, to the effect set forth in Schedule IV hereto.

                  (f) Subsequent to the date hereof, there shall not have
         occurred any change, or any development involving a prospective change,
         in or affecting the financial position, long-term debt, stockholders'
         equity or results of operations of First Union and its consolidated
         subsidiaries which the Representative concludes, after consultation
         with First Union, in the

                                       12







         judgment of the Representative is so material and adverse as to make it
         impractical or inadvisable to proceed with the public offering or the
         delivery of the Securities as contemplated by the Prospectus.

                  (g) First Union shall have furnished to the Representative
         such further information, certificates and documents as it may
         reasonably request prior to the Closing Date.

                  (h) Subsequent to the date of this Agreement, (i) no
         downgrading shall have occurred in the rating accorded First Union's
         unsecured debt securities or preferred stock by Standard & Poor's
         Ratings Group or by Moody's Investors Service, Inc. and (ii) neither
         such organization shall have publicly announced that it has under
         surveillance or review, with possible negative implications, its rating
         of any of First Union's unsecured debt securities or preferred stock.

                  If any of the conditions specified in this Section 6 shall not
have been fulfilled in all material respects when and as provided in this
Agreement, or if any of the opinions and certificates mentioned above or
elsewhere in this Agreement shall not be in all material respects reasonably
satisfactory in form and substance to the Representative and its counsel, this
Agreement and all obligations of the Underwriters hereunder may be canceled at,
or at any time prior to, the Closing Date by the Representative. Notice of such
cancellation shall be given to First Union in writing or by telephone or
telegraph confirmed in writing.

                  7.  Indemnification and Contribution.  (a)  First
Union agrees to indemnify and hold harmless each Underwriter
and each person who controls any Underwriter within the
meaning of either the Act or the Exchange Act against any
and all losses, claims, damages or liabilities, joint or
several, to which they or any of them may become subject
under the Act, the Exchange Act or other Federal or state
statutory law or regulation, at common law or otherwise,
insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon
any untrue statement or alleged untrue statement of a
material fact contained in the registration statement or in
any amendment thereof filed prior to the date hereof, or in
the Registration Statement or the Prospectus, or in any

                                       13







amendment thereof or supplement thereto, or in any related preliminary
prospectus or preliminary prospectus supplement, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
and agrees to reimburse each such indemnified party for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
that (i) First Union will not be liable in any such case to the extent that any
such loss, claim, damage or liability arises out of or is based upon any such
untrue statement or alleged untrue statement or omission or alleged omission
made therein in reliance upon and in conformity with written information
furnished to First Union by or on behalf of any Underwriter through the
Representative specifically for use in the Prospectus or any supplement thereto
or any related preliminary prospectus or preliminary prospectus supplement or of
the Statement of Eligibility (Form T-1) under the Trust Indenture Act of the
Trustee, and (ii) such indemnity with respect to any related preliminary
prospectus or preliminary prospectus supplement shall not inure to the benefit
of any Underwriter (or any person controlling such Underwriter) from whom the
person asserting any such loss, claim, damage or liability purchased the
Securities which are the subject thereof if such person was not sent or given a
copy of the Prospectus (or the Prospectus as amended or supplemented), excluding
documents incorporated therein by reference, at or prior to the confirmation of
the sale of such Securities to such person in any case where such delivery is
required by the Act and the untrue statement or omission of a material fact
contained in such related preliminary prospectus or preliminary prospectus
supplement was corrected in the Prospectus (or the Prospectus as amended or
supplemented). This indemnity agreement will be in addition to any liability
which First Union may otherwise have.

                  (b) Each Underwriter severally agrees to indemnify and hold
harmless First Union, each of its directors, each of its officers who signs the
Registration Statement, and each person who controls First Union within the
meaning of either the Act or the Exchange Act, to the same extent as the
foregoing indemnity from First Union to each Underwriter, but only with
reference to written information furnished to First Union by or on behalf of
such Underwriter through the Representative specifically for use in the Pro-


                                       14


spectus or any supplement thereto or any related preliminary prospectus or
preliminary prospectus supplement. This indemnity agreement will be in addition
to any liability which any Underwriter may otherwise have.

                  (c) Promptly after receipt by an indemnified party under
Section 7(a) or (b) of notice of the commencement of any action, such
indemnified party will, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify the indemnifying party in
writing of the commencement thereof; but the omission so to notify the
indemnifying party will not relieve the indemnifying party from any liability
which it may have to any indemnified party otherwise than under Section 7(a) or
(b). In case any such action is brought against any indemnified party, and it
notifies the indemnifying party of the commencement thereof, the indemnifying
party will be entitled to participate therein, and to the extent that it may
elect by written notice delivered to the indemnified party promptly after
receiving the aforesaid notice from such indemnified party, to assume the
defense thereof, with counsel satisfactory to such indemnified party; provided
that, if the defendants in any such action include both the indemnified party
and the indemnifying party and the indemnified party shall have reasonably
concluded that there may be legal defenses available to it and/or other
indemnified parties which are different from or additional to those available to
the indemnifying party, the indemnified party or parties shall have the right to
select separate counsel to assert such legal defenses and to otherwise
participate in the defense of such action on behalf of such indemnified party or
parties. Upon receipt of notice from the indemnifying party to such indemnified
party of its election so to assume the defense of such action and approval by
the indemnified party of counsel, the indemnifying party will not be liable to
such indemnified party under Section 7(a) or (b) for any legal or other expenses
subsequently incurred by such indemnified party (other than reasonable costs of
investigation) in connection with the defense thereof unless (i) the indemnified
party shall have employed separate counsel in connection with the assertion of
legal defenses in accordance with the proviso to the next preceding sentence
(it being understood, however, that the indemnifying party shall not be liable
for the expenses of more than one separate national counsel, approved by the
Representative, representing the indemnified parties who are parties to such
action), (ii) the indemnifying party shall not have employed

                                       15







counsel satisfactory to the indemnified party to represent the indemnified party
within a reasonable time after notice of commencement of the action or (iii) the
indemnifying party has authorized the employment of counsel for the indemnified
party at the expense of the indemnifying party; and except that, if clause (i)
or (iii) is applicable, such liability shall be only in respect of the counsel
referred to in such clause (i) or (iii).

                  (d) If the indemnification provided for in this Section 7 is
unavailable to or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above in respect of any losses, claims, damages or
liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative benefits received by First Union on the one hand and the Underwriters
of the Securities on the other from the offering of the Securities to which such
loss, claim, damage or liability (or action in respect thereof) relates. If,
however, the allocation provided by the immediately preceding sentence is not
permitted by applicable law or if the indemnified party failed to give the
notice required under subsection (c) above, then each indemnifying party shall
contribute to such amount paid or payable by such indemnified party in such
proportion as is appropriate to reflect not only such relative benefits but also
the relative fault of First Union on the one hand and the Underwriters of the
Securities on the other in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities (or actions in respect
thereof), as well as any other relevant equitable considerations. The relative
benefits received by First Union on the one hand and such Underwriters on the
other shall be deemed to be in the same proportion as the total net proceeds
from such offering (before deducting expenses) received by First Union bear to
the total underwriting discounts and commissions received by such Underwriters.
The relative fault 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 First Union on the one hand or such Underwriters on the other and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent

                                       16







such statement or omission. First Union and the Underwriters agree that it would
not be just and equitable if contribution pursuant to this subsection (d) 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
subsection (d). The amount paid or payable by an indemnified party as a result
of the losses, claims, damages or liabilities (or actions in respect thereof)
referred to above in this subsection (d) shall be deemed to include any legal or
other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this subsection (d), no Underwriter shall be required to
contribute any amount in excess of the amount by which the total price at which
the applicable 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 Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. The obligations of the Underwriters of Securities in this
subsection (d) to contribute are several in proportion to their respective
underwriting obligations with respect to the Securities and not joint.

                  8. Termination. This Agreement shall be subject to termination
in the absolute discretion of the Representative, by notice given to First Union
prior to delivery of and payment for the Securities, if prior to such time (i)
trading in securities generally on the New York Stock Exchange shall have been
suspended or materially limited, (ii) a general moratorium on commercial banking
activities in New York shall have been declared by either Federal or New York
State authorities, or (iii) there shall have occurred any material outbreak or
escalation of hostilities or other calamity or crisis the effect of which on the
financial markets of the United States is such as to make it, in the reasonable
judgment of the Representative, impracticable or inadvisable to proceed with the
public offering or the delivery of the Securities as contemplated by the
Prospectus.


                                       17







                  9. Substituted Underwriters. If, on the Closing Date, any one
or more of the Underwriters shall fail or refuse to purchase Securities that it
or they have agreed to purchase hereunder on such date, and the aggregate number
of Securities which such defaulting Underwriter or Underwriters agreed but
failed or refused to purchase is not more than one-tenth of the aggregate number
of the Securities to be purchased on the Closing Date, the other Underwriters
shall be obligated severally in the proportions that the number of Securities
set forth opposite their respective names in Schedule II bears to the aggregate
number of Securities set forth opposite the names of all such non-defaulting
Underwriters, or in such other proportions as the Underwriters may agree, to
purchase the Securities which such defaulting Underwriter or Underwriters agreed
but failed or refused to purchase on the Closing Date; provided that in no event
shall the number of Securities that any Underwriter has agreed to purchase
pursuant to Section 2 above be increased pursuant to this Section 9 by an amount
in excess of one-ninth of such number of Securities without the written consent
of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters
shall fail or refuse to purchase Securities and the aggregate number of
Securities with respect to which such default occurs is more than one-tenth of
the aggregate number of Securities to be purchased on the Closing Date, and
arrangements satisfactory to the Underwriters and First Union for the purchase
of such Securities are not made within 36 hours after such default, this
Agreement shall terminate without liability on the part of any non-defaulting
Underwriter or First Union. In such case either the Underwriters or First Union
shall have the right to postpone the Closing Date, but in no event for longer
than seven days, in order that the required changes, if any, in the Registration
Statement and in the Prospectus or in any other documents or arrangements may be
effected. Any action taken under this Section 9 shall not relieve any defaulting
Underwriter from liability in respect of any default of such Underwriter under
this Agreement.


                  10. Certain Liabilities Upon Termination. If this Agreement
shall be terminated pursuant to Section 9 hereof, the Company shall not then be
under any liability to any Underwriter except as provided in Sections 5(e) and 7
hereof; but, if for any other reason, any Securities are not delivered by or on
behalf of the Company as provided herein, the Company will reimburse the
Underwriters through you for all actual out-of-pocket expenses approved in
writing by

                                                   18







you, including fees and disbursements of counsel, reasonably incurred by the
Underwriters in making preparations for the purchase, sale and delivery of the
Securities not so delivered, but the Company shall then be under no further
liability to any Underwriter in respect of the Securities not so delivered
except as provided in Sections 5(e) and 7 hereof.

                  11. Representations and Indemnities to Survive. The respective
agreements, representations, warranties, indemnities and other statements of
First Union or its officers and of the Underwriters set forth in or made
pursuant to this Agreement will remain in full force and effect, regardless of
any investigation made by or on behalf of any Underwriter or First Union or any
of the officers, directors or controlling persons referred to in Section 7
hereof, and will survive delivery of and payment for the Securities. The
provisions of Sections 5(e), 7, 9, 12, 13 and 14 hereof shall survive the
termination or cancellation of this Agreement.

                  12. Successors. This Agreement will inure to the benefit of
and be binding upon the parties hereto (including any Underwriter or
Underwriters added pursuant to Section 9 hereof) and their respective
successors, heirs, executors, administrators and the officers and directors and
controlling persons referred to in Section 7 hereof, and no other person will
have any right or obligation hereunder.

                  13.  Applicable Law.  This Agreement will be
governed by and construed in accordance with the laws of the
State of New York.

                  14. Counterparts; Notices. This Agreement may be signed in any
number of counterparts, each of which shall be deemed an original, which taken
together shall constitute one and the same instrument.

                  15. Remarketing. If a prospectus is required by the Act to be
delivered in connection with offers and sales of the Securities (including any
offers and sales of Securities by the Callholder (as defined in the Prospectus
Supplement, including any assignee or successor of the Callholder) or the
Underwriters or any of their affiliates) following any proposed exercise of the
Call Option, the Floater Option or any other right resulting in an interest rate
reset and remarketing of the Securities (the "Call Option" and "Floater Option"
being as described in the

                                       19







Prospectus Supplement), and it is necessary, in the reasonable opinion of
counsel for the Underwriters or for First Union, at any such time to amend any
registration statement or amend or supplement any prospectus or prospectus
supplement in order that such prospectus or prospectus supplement will not
include any untrue statement of 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 under which made, or if it shall be necessary, in the
reasonable opinion of either such counsel, at any such time to amend any
registration statement or file a new registration statement or amend or
supplement any prospectus or issue a new prospectus or prospectus supplement in
order to comply with the requirements of the Act or the Commission's rules,
regulations or interpretations under the Act, First Union shall promptly prepare
and file with the Commission such amendment or supplement as may be necessary to
correct such statement or omission or to make any such registration statement or
any such prospectus or prospectus supplement comply with such requirements, or
promptly prepare and file any such new registration statement and prospectus as
either of such counsel may reasonably deem necessary for such purpose, and
furnish to the Callholder, the Underwriters, and any other persons participating
in the proposed distribution such number of copies of such amendment,
supplement, prospectus or other documents as they may reasonably request. In
addition, First Union shall, in connection with any such proposed offer or sale
of Securities by the Callholder, the Underwriters or any such other persons in
which a prospectus is required by the Act to be delivered, (i) execute and
deliver or cause to be executed and delivered legal documentation (including,
without limitation, a purchase agreement or underwriting agreement and
registration rights agreement with customary indemnities and contribution,
covenants, representations and warranties, expense provisions (but without
provision for express underwriting discounts or commissions), conditions,
comfort letters and legal opinions) in form and substance reasonably
satisfactory to First Union and counsel for the Underwriters, (ii) provide
promptly upon request updated consolidated financial statements to the date of
its latest report filed with the Commission, and (iii) to the extent First Union
and the Callholder, the Underwriters or any such other persons deem reasonably
necessary for successful completion of such offering and sale of the Securities,
make available senior management of First Union for road show and

                                       20







one-on-one presentations. This Section 15 shall not supercede or modify the
provisions of Section 5(d) of this Agreement.

                  All notices hereunder shall be in writing or by telegram if
promptly confirmed in writing, and if to the Underwriters shall be sufficient in
all respects if delivered or sent by registered mail to the address of the
Representative as set forth in Schedule I hereto; and if to First Union shall be
sufficient in all respects if delivered or sent by registered mail to the
address of First Union set forth in the Registration Statement, Attention:
Secretary; provided, however, that any notice to an Underwriter pursuant to
Section 7(c) hereof shall be delivered or sent by registered mail to such
Underwriter at its address set forth in its Underwriters' Questionnaire, or
telex constituting such Questionnaire, which address will be supplied to First
Union by the Representative upon request.

                  15. Action by Underwriters. Any action under this Agreement
taken by the Underwriters jointly or by the firm signing below on behalf of you
as the Representative will be binding upon all the Underwriters.


                                       21

our agreement, please sign and return to us the enclosed duplicate hereof,
