               under (S) 2(a) and ends (subject to (S) 2(b)(2) and (S) 2(b)(3))
               on the third anniversary of such effective date.

                    (2)  The Term of this Agreement shall automatically be
               extended for one additional year effective as of the first
               anniversary of the date on which this Agreement becomes effective
               under (S) 2(a) and one additional year effective as of each such
               anniversary date thereafter unless either Executive or SunTrust

               be no such one year extension before the beginning of the 90 day
               period which ends on the anniversary date on which such automatic
               one year extension otherwise would have been effective.

               in (S) 3(a) or if Executive's employment terminates under the
               circumstances described in (S) 3(f) before the Term of this
               Agreement (as extended, if applicable, under (S) 2(b)(2))
               expires, the then Term of this Agreement shall automatically be
               extended until the earlier of (1) the date Executive agrees that
               all SunTrust's obligations to Executive under this Agreement have
               been satisfied in full or (B) the date a final determination is

                    the date these provisions become effective or (3) the date
                    there is a Change in Control which can be accounted for on

          terms of such employee benefit plan, policy or program after a
          termination of Executive's employment without regard to this
          Agreement.

          terminates under any deferred compensation or welfare plan, policy or
          program (except a plan described in (S) 401 of the Code) maintained by
          SunTrust or a SunTrust Affiliate in which Executive is a participant
          and under which Executive's benefit, or eligibility for a benefit, is
          based in whole or in part on Executive's age or service or age and
          service, and Executive shall receive such age and service credit
          notwithstanding the terms of any such plan, policy or program.

                    -----------------------------------------------------
          Executive's employment terminates under the circumstances described in

          have any payment made under this (S) 3 taken into account to increase
          the benefits otherwise payable to, or on behalf of, Executive under
          any employee benefit plan, policy or program, whether qualified or
          nonqualified, maintained by SunTrust or a SunTrust Affiliate and,
          further, waives Executive's right, if any, to the payment of severance
          pay under any severance pay plan, policy or program maintained by
          SunTrust or a SunTrust Affiliate subject to the condition that
          SunTrust not be relieved of any of its obligations to Executive under
          this (S) 3 pursuant to (S) 3(g) or (S) 3(h).

                    -------------------
          have no obligations to Executive under this (S) 3 if Executive's

                                 Tax Protection
                                 --------------

          If SunTrust or SunTrust's independent accountants determine that any
payments and benefits called for under this Agreement together with any other
payments and benefits made available to Executive by SunTrust or a SunTrust
Affiliate will result in Executive being subject to an excise tax under (S) 4999
of the Code or if such an excise tax is assessed against Executive as a result
of any such payments and other benefits, SunTrust shall make a Gross Up Payment
to or on behalf of Executive as and when any such determination or assessment is
made, provided Executive takes such action (other than waiving Executive's right
to any payments or benefits) as SunTrust reasonably requests under the
circumstances to mitigate or challenge such tax.  Any determination under this
(S) 9 by SunTrust or SunTrust's independent accountants shall be made in
accordance with (S) 280G of the Code and any applicable related regulations
(whether proposed, temporary or final) and any related Internal Revenue Service
rulings and any related case law and, if SunTrust reasonably requests that
Executive take action to mitigate or challenge, or to mitigate and challenge,
any such tax or assessment (other than waiving Executive's right to any payment
or benefit) and Executive complies with such request, SunTrust shall provide
Executive with such information and such expert advice and assistance from
SunTrust's independent accountants, lawyers and other advisors as Executive may
reasonably request and

                                      -15-

shall pay for all expenses incurred in effecting such compliance and any related
fines, penalties, interest and other assessments.

                                    (S) 10.
