                             1988 STOCK OPTION PLAN

               (As Amended by the Shareholders on April 26, 1990,
                             and on April 23, 1992)


1.     PURPOSES OF THE PLAN

       The purpose of the KeyCorp 1988 Stock Option Plan is to provide a method
       by which those employees of KeyCorp and its Subsidiaries who are largely
       responsible for the management, growth, and protection of the business,
       and who are making and can continue to make substantial contributions to
       the success of the business, may be encouraged to acquire a larger stock
       ownership in KeyCorp, thus increasing their proprietary interest in the
       business, providing them with greater incentive for their continued
       employment, and promoting the interests of KeyCorp and all of its
       shareholders.  Accordingly, KeyCorp will, from time to time during the
       term of the Plan, grant to such key employees as may be selected, in the
       manner provided in the Plan, options to purchase shares of Common Stock
       of KeyCorp and stock appreciation rights for use in connection with the
       stock options, subject to the conditions provided in the Plan.

               Board of Directors and selected from those Directors who are not
               employees of KeyCorp or a Subsidiary.  The





                                      -2-
   3
       Board may from time to time remove members from or add members to the
       Committee.  Vacancies on the Committee, howsoever caused, shall be
       filled by the Board.  The Board shall select one of the Committee's
       members as Chairman.  The Committee shall hold meetings at such times
       and places as it may determine, subject to such rules as to procedures
       not inconsistent with the provisions of the Plan as are prescribed by
       the Board, set forth in KeyCorp's By-Laws as applicable to the Executive
       Committee, and as prescribed by the Committee itself.  A majority of the
       authorized number of members of the Committee shall constitute a quorum
       for the transaction of business.  Acts reduced to or approved in writing
       by a majority of the members of the Committee then serving shall be the
       valid acts of the Committee.  No member of the Committee shall be
       eligible to be granted Options or Rights under the Plan while a member
       of the Committee.

       (b)     The Committee shall be vested with full authority to make such
               rules and regulations as it deems necessary or desirable to
               administer the Plan and to interpret the provisions of the Plan.
               Any determination, decision, or action of the Committee in
               connection with the construction, interpretation,
               administration, or application of the Plan shall be final,
               conclusive, and binding upon all Optionees and any person
               claiming under or through an Optionee unless otherwise
               determined by the Board.

       (c)     Any determination, decision, or action of the Committee provided
               for in the Plan may be made or taken by action of the Board, if
               it so determines, with the same force and effect as if such
               determination, decision, or action had been made or taken by the
               Committee. No member of the Committee or of the Board shall be
               liable for any determination, decision, or action made in good
               faith with respect to the Plan or any Option or Right granted
               under the Plan.  The fact that a member of the Board who is not
               then a member of the Committee shall at the time be, or shall
               theretofore have been, or thereafter may be a person who has
               received or is eligible to receive an Option or Right shall not
               disqualify him or her from taking part in and voting
               at any time as a member of the Board in favor of or against any
               amendment or repeal of the Plan,





                                      -3-
   4
       provided that such vote shall be in accordance with the recommendations
       of the Committee.

4.     STOCK SUBJECT TO THE PLAN

       (a)     The Common Stock to be issued or transferred under the Plan will
               be KeyCorp Common Stock which shall be made available, at the
               discretion of the Board, either from authorized but unissued
               Common Stock or from Common Stock reacquired by KeyCorp,
               including shares purchased in the open market.  The maximum
               number of shares of Common Stock upon which Options may be
               granted in each year under this Plan shall not exceed 2 percent
               of the total issued and outstanding shares of Common Stock as of
               December 31 of the next preceding year, as adjusted pursuant to
               Section 15 of the Plan, provided, however, that for each year in
               which the Plan is in effect, no more than 750,000 of the total
               issued and outstanding shares of Stock shall be available for
               the grant of Incentive Stock Options under this Plan.  Unused
               grant capacity shall not cumulate from one year to the next.

       (b)     In the event that any outstanding Option or Right under the Plan
               for any reason expires or is terminated, the shares of Common
               Stock allocable to the unexercised portion of such Option or
               Right may again be made subject to Option or Right under the
               Plan.

5.     GRANT OF OPTIONS

       The Committee may from time to time, subject to the provisions of the
       Plan, grant Options to key employees of KeyCorp or of a Subsidiary to
       purchase shares of Common Stock allotted in accordance with Section 4 of
       the Plan.  The Committee may designate any Option granted as either an
       incentive Stock Option or a Non-Qualified Stock Option, or the Committee
       may designate a portion of the Option as an Incentive Stock Option and
       the remaining portion as a Non-Qualified Stock Option.  If an Optionee
       exercises an Option, then at the discretion of the Committee or pursuant
       to the terms of the original Option, the Optionee may receive a
       replacement Option to purchase a number of shares of Common Stock
       determined by the Committee or the terms of the original Option, with an
       option price determined under Section 6 of the Plan as of the date of
       exercise of the original Option and with a term extending to the
       expiration date of the original Option.





                                      -4-

6.     OPTION PRICE

       The purchase price per share of any Option granted under the Plan shall
       be 100 percent of the fair market value of one share of Common Stock on
       the date the Option is granted, except that the purchase price per share
       shall be 110 percent of the fair market value in the case of an
       Incentive Stock Option granted to an individual described in subsection
       8(b) of the Plan.  For purposes of the Plan, the fair market value of a
       share of Common Stock shall be equal to the highest closing price of one
       share of Common Stock as reported for consolidated trading on the New
       York Stock Exchange (or such other national securities exchange on which
       the Common Stock may be principally traded) on the date the Option is
       granted, or if no sale of Common Stock has been made on any securities
       exchange on that day, the fair market value shall be determined by
       reference to such price for the next preceding day on which a sale
       occurred.  During such time as Common Stock is not listed on a national
       securities exchange, fair market value per share shall be the mean
       between the closing dealer "bid" and "ask" prices for Common Stock as
       quoted by National Association of Securities Dealers Automated Quotation
       System for the day of the grant, and if no "bid" and "ask" prices are
       quoted for the day of grant, the fair market value shall be determined
       by reference to such prices on the next preceding day on which such
       prices were quoted.  In the event that Common Stock is not traded on a
       national securities exchange, and no closing dealer "bid" and "ask"
       prices are available, then the fair market value of one share of Common
       Stock on the day the Option is granted shall be determined by the
       Committee or by the Board.  The purchase price shall be subject to
       adjustment only as provided in Section 15 of the Plan.

7.     GRANT OF RIGHTS

       The Committee may, at any time and in its discretion, grant to any
       employee of KeyCorp or any of its subsidiaries who is awarded or who
       holds an outstanding Option or any other outstanding stock option
       granted by KeyCorp, the right to surrender such Option (to the extent
       any Option or such other stock option is otherwise exercisable) and to
       receive from KeyCorp an amount equal to the excess, if any, of the fair
       market value of the Common Stock with respect to which such Option is
       surrendered on the date of such surrender over the option price of the
       Option or other stock option surrendered.  Payment of KeyCorp of the
       amount receivable upon any exercise of a Right may be made by





                                      -5-
   6
       delivery of Common Stock, or cash, or any combination of Common Stock
       and cash, as determined in the sole discretion of the Committee from
       time to time.  No fractional shares shall be issued.  The Committee may
       provide for the elimination of fractional shares of Common Stock
       delivered to the Optionee without adjustment or for the payment of the
       value of such fractional shares in cash.  Shares of KeyCorp Common Stock
       delivered to the Optionee upon the exercise of a Right, and the
       surrender of the Option or stock option, shall be valued at the fair
       market value (determined pursuant to Section 6) of a share of Common
       Stock on the date the right is exercised and the Option or stock option
       is surrendered.  The Committee may limit the period or periods during
       which the Rights may be exercised and may provide such other terms and
       conditions (which need not be the same with respect to each Optionee)
       under which a Right may be granted and/or exercised.  A Right may be
       exercised only as long as the related Option or stock option is
       exercisable.  In no event may a Right be exercised more than ten years
       after the date of the grant of the related Option or stock option.  A
       right may not be granted with respect to an Incentive Stock Option at
       any time other than at the same time the Incentive Stock Option is
       granted.  Rights granted with respect to Incentive Stock Options (a)
       shall expire no later than the expiration of the underlying Option, (b)
       shall be for no more than the difference between the exercise price of
       the underlying option and the market price of the stock subject to the
       underlying option at the time the right is exercised, (c) shall be
       transferrable only when the underlying Option is transferrable and under
       the same conditions, (d) shall be exercisable only when the underlying
       Option is exercisable, and (e) shall be exercisable only when the market
       price of the stock subject to the underlying Option exceeds the exercise
       price of the Option.

8.     ELIGIBILITY OF OPTIONEES

       (a)     Options and Rights shall be granted only to persons who are key
               employees of KeyCorp or of a Subsidiary as determined by the
               Committee at the time of grant.  The term "employees" shall
               include persons who are Directors or Officers who are also
               employees of KeyCorp or of any Subsidiary.

       (b)     Any other provision of the Plan notwithstanding, an individual
               who owns more than ten percent of the total combined voting
               power of all classes of outstanding Common Stock of KeyCorp or
               any





                                      -6-
   7
               Subsidiary shall not be eligible for the grant of an Incentive
               Stock Option unless the special requirements set forth in
               Sections 6 and 10(a) of the Plan are satisfied.  For purposes of
               this subsection (b), in determining stock ownership, an
               individual shall be considered as owning the stock owned,
               directly or indirectly, by or for his or her brothers and
               sisters, spouse, ancestors, and lineal descendants.  Stock
               owned, directly or indirectly, by or for a corporation,
               partnership, estate, or trust shall be considered as being owned
               proportionately by or for its shareholders, partners, or
               beneficiaries.  Stock with respect to which such individual
               holds an Option shall not be counted.  Outstanding stock shall
               include all stock actually issued and outstanding immediately
               after the grant of the Option.  Outstanding stock shall not
               include shares authorized for issue under outstanding Options
               held by the Optionee or by another person.

       (c)     Subject to the terms, provisions, and conditions of the Plan and
               subject to review by the Board, the Committee shall have
               exclusive jurisdiction to (1) select the key employees to be
               granted Options or Rights (it being understood that more than
               one Option or Right may be granted to the same person), (2)
               determine the number of shares subject to each Option or Right,
               (3) determine the date or dates when the Options or Rights will
               be granted, (4) determine the purchase price of the shares
               subject to each Option in accordance with Section 6 of the Plan,
               (5) determine the date or dates when each Option or Right may be
               exercised within the term of the Option specified pursuant to
               Section 10 of the Plan, (6) determine whether or not an Option
               constitutes an Incentive Stock Option, and (7) prescribe the
               form, which shall be consistent with the Plan, of the documents
               evidencing any Options or Rights granted under the Plan.

       (d)     Neither anything contained in the Plan or in any document under
               the Plan nor the grant of any Option or Right under the Plan
               shall confer upon any Optionee any right to continue in the
               employ of KeyCorp or of any Subsidiary or limit in any respect
               the right of Key Corp or of any Subsidiary to terminate the
               Optionee's employment at any time and for any reason.





                                      -7-

9.     NON-TRANSFERABILITY

       No Option or Right granted under the Plan shall be assignable or
       transferable by the Optionee other than by will or the laws of descent
       and distribution; and during the lifetime of an Optionee, the Option
       shall be exercisable only by such Optionee.

10.    TERM AND EXERCISE OF OPTIONS AND RIGHTS

       (a)     Each Option or Right granted under the Plan shall terminate on
               the date determined by the Committee and specified in the Option
               Agreement, provided that each Option shall terminate not later
               than ten years after the date of grant.  However, any Option
               designated as an Incentive Stock Option granted to a more than
               ten percent shareholder shall terminate not later than five
               years after the date of grant.  The Committee, at its
               discretion, may provide further limitations on the
               exercisability of Options or rights granted under the Plan.  An
               Option or Right may be exercised only during the continuance of
               the Optionee's employment, except as provided in Section 11 of
               the Plan.

       (b)     A person electing to exercise an Option or Right shall give
               written notice to KeyCorp, in such form as the Committee shall
               have prescribed or approved, of such election and of the number
               of shares he or she has elected to purchase and shall at the
               time of exercise tender the full purchase price of any shares he
               or she has elected to purchase.  The purchase price upon the
               exercise of an Option shall be paid in full in cash, provided,
               however, that in lieu of cash, with the approval of the
               Committee at or prior to exercise, an Optionee may exercise his
               or her Option by tendering to KeyCorp shares of Common Stock
               owned by him or her and having a fair market value equal to the
               cash exercise price applicable to his or her Option, with the
               then fair market value of such stock to be determined in the
               manner provided in Section 6 of the Plan (with respect to the
               determination of the fair market value of Common Stock on the
               date an Option is granted).  However, if an Optionee pays the
               Option exercise price of a Non-Qualified Stock Option in whole
               or in part in the form of unrestricted Common Stock already
               owned by the Optionee, KeyCorp may require that the Optionee
               have owned the stock for a period of time that would not cause
               the exercise to create a





                                      -8-
   9
               charge to KeyCorp's earnings.  Such provision may be used by
               KeyCorp to prevent a pyramid exercise.  As conditions to
               exercising an Option or a Right, the holder must (1) arrange to
               pay to KeyCorp any amount required to be withheld under any tax
               law on the account of the exercise, and (2) in the case of an
               Incentive Stock Option, agree to notify KeyCorp of any
               disqualifying disposition (as defined in Section 421 of the
               Code) of the Common Stock acquired upon the exercise and agree
               to pay to KeyCorp any amount required to be withheld under any
               tax law on account of the disposition.  Any payment on account
               of withholding taxes shall be made in a form acceptable to
               the Committee.

       (c)     An Optionee or a transferee of an Option shall have no rights as
               a shareholder with respect to any shares covered by his or her
               Option or Right until the date the Stock Certificate is issued
               evidencing ownership of the shares.  No adjustments shall be
               made for dividends (ordinary or extraordinary), whether in cash,
               securities, or other property, or distributions, or other rights
               for which the record date is prior to the date such Stock
               Certificate is issued, except as provided in Section 15 of the
               Plan.

       (d)     A person may, in accordance with the other provisions of the
               Plan, elect to exercise Options or Rights in any order,
               notwithstanding the fact that Options or Rights granted to him
               or her prior to the grant of the Options or Rights selected for
               exercise are unexpired.

11.    TERMINATION OF EMPLOYMENT

       If an Optionee severs from all employment with KeyCorp and/or its
       Subsidiaries, any Option or Right granted to him or her under the Plan
       shall terminate as follows:

       (a)     An Option or Right held by an Optionee who is permanently and
               totally disabled within the meaning of Section 22(e)(3) of the
               Code shall terminate upon its expiration date;

       (b)     An Option or Right held by an Optionee shall be exercisable
               within a period of one year from the date of Optionee's death by
               the executor or





                                      -9-
   10
               administrator of the Optionee's estate or by the person to whom
               the Optionee shall have transferred such right by last Will and
               Testament or by the laws of descent or distribution;

       (c)     An Option or Right held by an Optionee who terminates for cause,
               as determined by the Committee, shall expire immediately upon
               the date of termination unless some other expiration date is
               fixed by the Committee; and

       (d)     An Option or Right held by an Optionee who terminates for any
               reason other than those specified in subsections (a), (b), or
               (c) above shall expire three months after the date of
               termination unless a later expiration date is fixed by the
               Committee.

       The foregoing notwithstanding, no Option or Right shall be exercisable
       after its expiration date.

       Whether an authorized leave of absence or an absence for military or
       governmental service shall constitute termination of employment for
       purposes of the Plan shall be determined by the Committee, which
       determination shall be final, conclusive, and binding upon the affected
       Optionee and any person claiming under or through such Optionee.
       Termination or employment with any subsidiary of KeyCorp in order to
       accept employment with another subsidiary of KeyCorp or while remaining
       an employee of KeyCorp or of any of its subsidiaries shall not be a
       termination of employment for the purposes of this Section 11.

12.    MODIFICATION, EXTENSION, AND RENEWAL

       Subject to the terms and conditions and within the limitations of the
       Plan, the Committee may modify, extend, or renew outstanding Options or
       Rights (to the extent not theretofore exercised) and authorize the
       granting of new Options or Rights in substitution therefor.  Without in
       any way limiting the generality of the foregoing, the Committee may
       grant to an Optionee, if he or she is otherwise eligible and consents
       thereto, a new or modified Option or Right in lieu of an outstanding
       Option or Right for a number of shares at an exercise price and for a
       term which are greater or less than under the earlier Option or Right or
       may do so by cancellation and re-grant, amendment, substitution, or
       otherwise subject only to the general limitations and conditions of the
       Plan.  The foregoing notwithstanding, no modification of an Option or
       Right





                                      -10-
   11
       shall, without the consent of the Optionee, alter or impair any rights
       or obligations under any Option or Right theretofore granted under the
       Plan.

13.    PERIOD IN WHICH GRANTS MAY BE MADE

       Options and Rights may be granted pursuant to the Plan at any time on or
       before April 26, 2000.

14.    AMENDMENT OR TERMINATION OF THE PLAN

       The Board may at any time terminate, amend, modify, or suspend the Plan,
       provided that, without the approval of the shareholders of KeyCorp, no
       amendment or modification shall be made by the Board which (a) increases
       the maximum number of shares as to which Options or Rights may be
       granted under the Plan; (b) alters the method by which the Option price
       is determined; (c) extends any Option or Right for a period longer than
       ten years after the date of the grant; (d) materially modifies the
       requirements as to eligibility for participation in the Plan; or (e)
       alters this Section 14 so as to defeat its purpose.  Further, no
       amendment, modification, suspension, or termination of the Plan shall in
       any manner affect any Option or Right theretofore granted under the Plan
       without the consent of the Optionee or any person validly claiming under
       or through the Optionee.

15.    CHANGES IN CAPITALIZATION

       (a)     In the event that the shares of KeyCorp, as presently
               constituted, shall be changed into or exchanged for a different
               number or kind of shares of stock or other securities of KeyCorp
               or of another corporation (whether by reason of merger,
               consolidation, recapitalization, reclassification, split-up,
               combination of shares, or otherwise), or if the number of such
               shares of stock shall be increased through the payment of a
               stock dividend, then subject to the provisions of subsection (c)
               below, there shall be substituted for or added to each share of
               stock of KeyCorp which was theretofore appropriated or which
               thereafter may become subject to an Option or Right under the
               Plan the number and kind of shares of stock or other securities
               into which each outstanding share of Common Stock of KeyCorp
               shall be so changed, or for which each such share shall be
               exchanged or to which each such share shall be entitled, as the
               case may be.  Outstanding Options and Rights shall also be
               appropriately amended as to price and





                                      -11-
   12
               other terms as may be necessary to reflect the foregoing events. 
               The maximum number of shares of Common Stock upon which Options
               and Incentive Stock Options may be granted, as provided in
               Section 4(a) of the Plan, shall be proportionately adjusted to
               reflect any of the foregoing events.

       (b)     If there shall be any other change in the number or kind of
               outstanding shares of stock of KeyCorp, or of any stock or other
               securities into which such stock shall have been changed, or for
               which it shall have been exchanged, and if the Board or the
               Committee, as the case may be, shall, in its sole discretion,
               determine that such change equitably requires an adjustment in
               any Option or Right which was theretofore granted or which may
               thereafter be granted under the Plan, then such adjustment shall
               be made in accordance with such determination.

       (c)     A dissolution or liquidation of KeyCorp or a merger or
               consolidation in which KeyCorp is not the surviving corporation
               shall cause each outstanding Option and Right to terminate,
               except to the extent that another corporation may and does in
               the transaction assume and continue the Option or substitute its
               own options.  In either event, the Board or the Committee, as
               the case may be, shall have the right to accelerate the time
               within which the Option or Right may be exercised.

       (d)     Fractional shares resulting from any adjustment in Options or
               Rights pursuant to this Section 15 may be settled as the Board
               or the Committee, as the case may be, shall determine.

       (e)     To the extent that the foregoing adjustments relate to stock or
               securities of KeyCorp, such adjustments shall be made by the
               Committee, whose determination in that respect shall be final,
               binding, and conclusive.  Notice of any adjustment shall be
               given by KeyCorp to each holder of an Option or Right which
               shall have been so adjusted.

       (f)     The grant of an Option or Right pursuant to the Plan shall not
               affect in any way the right or power of KeyCorp to make
               adjustments, reclassifications, reorganizations, or changes of
               its capital or business structure or to merge, consolidate,
               dissolve, liquidate, sell, or transfer all or any part of its
               business or asset.

16.  LISTING AND REGISTRATION OF SHARES

       (a)     No Option or Right granted pursuant to the Plan shall be
               exercisable in whole or in part if at any time the Board or the
               Committee, as the case may be, shall determine, in its
               discretion, that the listing, registration, or qualification of
               the shares of Common Stock subject to such Option or Right on
               any securities exchange or under any applicable law, or the
               consent or approval of any governmental regulatory body, is
               necessary or desirable as a condition of or in connection with
               the granting of such Option or Right or the issue of shares
               thereunder unless such listing, registration, qualification,
               consent, or approval shall have been effected or obtained free
               of any conditions not acceptable to the Board.

       (b)     If a registration statement under the Securities Act of 1933
               with respect to shares issuable upon exercise of any Option or
               Right granted under the Plan is not in effect at the time of
               exercise, the person exercising such Option or Right shall give
               the Committee a written statement, satisfactory in form and
               substance to the Committee, that he or she is acquiring the
               shares for his or her own account for investment and not with a
               view to their disposition.  KeyCorp may place upon any Stock
               Certificate for shares issuable upon exercise of such Option or
               Right such legend as the Committee may prescribe to prevent
               disposition of the shares in violation of the Securities Act of
               1933 or any other applicable law.

17.    EFFECTIVE DATE OF PLAN

       The Plan was approved by KeyCorp's shareholders at the Annual Meeting of
       Shareholders held on April 23, 1992, and became effective on that date.
