OVERVIEW

SUMMARY OF CONTEST

MFS INTERMEDIATE INCOME TRUST

o   THE FUND'S BOARD IS INDEPENDENT AND ENGAGED.
      > The Chairman is independent of MFS as are ten of the twelve Trustees.
      > The Trustees and the Fund have independent counsel.

o   THE TRUSTEES HAVE:
      > Taken actions to enhance net asset value and narrow the discount.
      > Overseen good performance and met the Fund's investment objective.

DISSIDENT SHAREHOLDER

o   KARPUS' INTERESTS ARE NOT ALIGNED WITH ALL SHAREHOLDERS.
      > Within the past year, Karpus has more than doubled its holdings in the
        Fund, purchasing shares below NAV, and is now trying to coerce the
        Board into adopting a strategy that would enable Karpus to cash out at
        a profit, regardless of that strategy's adverse effect on the Fund's
        remaining shareholders or its long-term efficacy in narrowing the
        discount.

o   KARPUS'S APPROACH WILL HAVE AN ADVERSE IMPACT ON LONG-TERM SHAREHOLDERS.

DIALOGUE WITH KARPUS

o   MFS is responsive to shareholders and committed to dialogue with our
    shareholders.

o   MFS has an established history of dialogue with Karpus on a different MFS
    fund.

o   October 2007, before Karpus raises any concerns, the Fund announces Board
    approval of level distribution plan and change in investment strategy to
    provide a more competitive yield.
      > Annual distribution rate of 8.5%.
      > Increased investment in higher yielding investment-grade securities.

o   Karpus sends e-mail in response on the day the plan is announced: "Very
    pleased with press release this morning. I think it was best for all
    concerned. Great work!"

o   January 2008 - Karpus again praises the Board's actions regarding the
    discount, noting that the "Board's actions reflect their commitment to
    address" the discount. In the same letter, Karpus expresses concern that
    the investment strategy change increases risk.

o   March 2008 - Trustees respond, noting that it was premature to judge the
    effect of distributions that commenced in January, adding that Karpus had
    displayed confidence in Fund management by acquiring nearly 1 million
    additional shares in January 2008/December 2007.

o   March 2008 - Karpus submits shareholder proposal for annual tender offers.

o   May 2008 - Karpus notifies the Fund of its intention to nominate four
    trustees for election at the October 2008 shareholder meeting.

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


DIALOGUE WITH KARPUS (CONTINUED)

o   The Board carefully considered Karpus' nominees.
      > Requested and reviewed detailed information about nominees - the same
        information requested of any nominee considered by the Board.
      > One of Karpus' nominees did not respond to the Board's request for
        additional information and was not interviewed.
      > One of Karpus' nominees declined to interview on any of the three
        dates offered, even after the committee offered to conduct the
        interview via video conference.
      > The Board's nomination committee interviewed two Karpus nominees.

INDEPENDENT, ENGAGED AND EXPERIENCED TRUSTEES

EACH OF THE BOARD'S NOMINEES, SIMILAR TO THE CONTINUING TRUSTEES, HAS MANY

    independent Chairman of MFS Funds Board of Trustees; certified public
    accountant; Trustee of MFS funds since 1992.

o   WILLIAM R. GUTOW - Vice Chairman of Capitol Entertainment Company and
    Atlantic Coast Tan; real estate consultant; attorney; trustee of MFS funds
    since 1993.

o   MICHAEL HEGARTY - Retired Vice Chairman and COO of AXA Financial; former

(C) 2008 MFS Investment Management(R) 500 Boylston Street, Boston, MA  02116


ELECTION OF TRUSTEES

KARPUS' NOMINEES LESS QUALIFIED

o   The Board's four nominees are better qualified to serve as closed-end fund
    trustees.

o   Karpus has a history of self-serving activism against closed-end funds. In
    spite of its expressed displeasure at the modifications of the Fund's
    investment strategy, it increased its holdings from 5.10% of the Fund's
    assets in April 2007 to 11.98% in May 2008.

o   None of Karpus' nominees has any experience serving as trustee of a
    closed-end fund that invests in public securities. In fact, only one of
    Karpus' nominees has ever served on the board of any public company at all.

o   Karpus' nominees may be conflicted - will they serve the interests of all
    shareholders or the investors whose assets are managed by Karpus?
      > The Trustees believe Karpus' nominees would advocate for Karpus'
        proposals even if not in the best interest of all shareholders.

o   In an August 2008 letter to the Fund's Trustees, one of the Karpus'
    nominees indicated that he wasn't "sure the discount is the primary issue"
    and advocated an active share repurchase plan. The current Trustees have
    already authorized such a plan.

                                                          M F S(R)
                                                          INVESTMENT MANAGEMENT

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

(C) 2008 MFS Investment Management(R) 500 Boylston Street, Boston, MA  02116


SHAREHOLDER PROPOSAL

o   Karpus' proposal requests that the Trustees adopt a policy that if the
    Fund's shares trade at an average discount of greater than 6% over the
    final 12 weeks previous to the end of October each year, the Board will
    conduct a tender offer for at least 10% of the shares at 99% of net asset
    value by the end of that calendar year.

      o Karpus is requesting that shareholders vote for annual tender offers by
        the Fund as a means to narrow the Fund's discount.

      o There is no evidence that periodic tenders narrow discounts over the
        long-term - they provide temporary liquidity above market value and
        primarily benefit speculators.

o   In difficult economic times such as the present, the proposal, applied to
    the universe of closed-end funds, would trigger tender offers by more than
    85% of closed-end funds.

                                                          M F S(R)

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

(C) 2008 MFS Investment Management(R) 500 Boylston Street, Boston, MA  02116


SHAREHOLDER PROPOSAL (CONTINUED)

o   If the Fund were to adopt the proposal, the Trustees believe that:
      > Expenses for long-term shareholders would likely increase.
          o MFS estimates that the Fund's expense ratio would increase by
            approximately 0.08% in the first year of mandatory tender due to
            the reduction in asset base and costs to conduct the tender.
      > Arbitrageurs could take advantage of the inflexible tender requirement
        to the detriment of long-term shareholders.
      > The portfolio would not be able to remain fully invested during the
        pendency of the tender.
          o An inflexible tender requirement in November or December in any
            year would be operative without regard to prevailing market
            conditions and the portfolio manager's judgment as to whether it is
            in the best interest of the Fund to liquidate 10% of its assets and
            incur associated costs to conduct the self-tender.
      > Open-market repurchases are a better vehicle to build value for
        long-term shareholders.
          o The fund has a policy to purchase shares in open market
            transactions when shares trade at a substantial discount. By
            providing that repurchases occur at market prices, the policy
            enables the Fund to provide liquidity to departing shareholders
            while at the same time building value for remaining shareholders
            who benefit from the difference between net asset value and market
            price.

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

(C) 2008 MFS Investment Management(R) 500 Boylston Street, Boston, MA  02116


SHAREHOLDER PROPOSAL (CONTINUED)

o   However, the Board has taken actions to address the discount:
      > In October 2007, the Board authorized the adoption of a
        level-distribution plan pursuant to which the Fund will make monthly
        distributions at a minimum annual rate of 8.50%. The plan took effect
        in January 2008. In October and December, 2007, the Board approved
        changes in the Fund's investment strategy as a means to potentially
        increase yield.
      > In October and December, 2007, the Board approved changes in the Fund's
        investment strategy as a means to potentially increase yield.
      > In June 2008, the Board approved a more aggressive share repurchase
        policy than had previously been in effect.

o   In addition, the Board conducts an annual comprehensive review of
    closed-end markets and options to address discounts, and will continue to
    review the Fund's discount at quarterly meetings.

o   The Board believes that these actions are meaningful and responsive to the
    dissidents' expressed concern about the Fund's discount.

o   The Board believes these actions should be afforded an opportunity to serve
    their intended purpose prior to taking any further actions to address the
    Fund's discount.
