###    Floating rate note obligation related to securities held. The interest
       rates shown reflect the rates in effect at July 31, 2007.

(a)    The Trust invests in Morgan Stanley Institutional Liquidity Tax-Exempt
       Portfolio - Institutional Class, an open-end management investment
       company managed by the Investment Adviser. Investment Advisory fees paid
       by the Trust are reduced by an amount equal to the advisory and
       administrative service fees paid by Morgan Stanley Institutional
       Liquidity Tax-Exempt Portfolio - Institutional Class with respect to
       assets invested by the Trust in Morgan Stanley Institutional Liquidity
       Tax-Exempt Portfolio - Institutional Class. Income distributions earned
       by the trust totaled $38,908 for the period ended July 31, 2007.

(b)    Floating Rate Note Obligations Related to Securities Held - The Trust
       enters into transactions in which it transfers to Dealer Trusts ("Dealer
       Trusts"), fixed rate bonds in exchange for cash and residual interests in
       the Dealer Trusts' assets and cash flows, which are in the form of
       inverse floating rate investments. The Dealer Trusts fund the purchases
       of the fixed rate bonds by issuing floating rate notes to third parties
       and allowing the Trust to retain residual interest in the bonds. The
       Trust enters into shortfall agreements with the Dealer Trusts which
       commit the Trust to pay the Dealer Trusts, in certain circumstances, the
       difference between the liquidation value of the fixed rate bonds held by
       the Dealer Trusts and the liquidation value of the floating rate notes
       held by third parties, as well as any shortfalls in interest cash flows.
       The residual interests held by the Trust (inverse floating rate
       investments) include the right of the Trust (1) to cause the holders of
       the floating rate notes to tender their notes at par at the next interest
       rate reset date, and (2) to transfer the municipal bond from the Dealer
       Trusts to the Trust, thereby collapsing the Dealer Trusts. The Trust
       accounts for the transfer of bonds to the Dealer Trusts as secured
       borrowings, with the securities transferred remaining in the Trust's
       investment assets, and the related floating rate notes reflected as Trust
       liabilities. The notes issued by the Dealer Trusts have interest rates
       that reset weekly and the floating rate note holders have the option to
       tender their notes to the Dealer Trusts for redemption at par at each
       reset date. At July 31, 2007, Trust investments with a value of
       $101,351,595 are held by the Dealer Trusts and serve as collateral for
       the $71,260,000 in floating rate note obligations outstanding at that
       date. Contractual maturities of the floating rate note obligations and
       interest rates in effect at July 31, 2007 are presented in the "Portfolio
       of Investments".

(c)    Securities have been designated as collateral in an amount equal to
       $47,121,788 in connection with open futures contracts and an open swap
       contract.

(d)    The aggregate cost for federal income tax purposes approximates the
       aggregate cost for book purposes. The aggregate gross unrealized
       appreciation is $17,018,471 and the aggregate gross unrealized
       depreciation is $4,027,197, resulting in net unrealized appreciation of
       $12,991,274.

                  CERTIFICATION OF PRINCIPAL FINANCIAL OFFICER

I, Francis Smith, certify that:

1.   I have reviewed this report on Form N-Q of Morgan Stanley Quality Municipal
     Income Trust;

2.   Based on my knowledge, this report does not contain any untrue statement of
     a material fact or omit to state a material fact necessary to make the
     statements made, in light of the circumstances under which such statements
     were made, not misleading with respect to the period covered by this
     report;

3.   Based on my knowledge, the schedules of investments included in this report
     fairly present in all material respects the investments of the registrant
     as of the end of the fiscal quarter for which the report is filed;

4.   The registrant's other certifying officer(s) and I are responsible for
     establishing and maintaining disclosure controls and procedures (as defined
     in Rule 30a-3(c) under the Investment Company Act of 1940) for the
     registrant and have:

     (a)  Designed such disclosure controls and procedures, or caused such
          disclosure controls and procedures to be designed under our
          supervision, to ensure that material information relating to the
          registrant, including its consolidated subsidiaries, is made known to
          us by others within those entities, particularly during the period in
          which this report is being prepared;

     (b)  Omitted;

     (c)  Evaluated the effectiveness of the registrant's disclosure controls
          and procedures and presented in this report our conclusions about the
          effectiveness of the disclosure controls and procedures, as of a date
          within 90 days prior to the filing date of this report, based on such
          evaluation; and

     (d)  Disclosed in this report any change in the registrant's internal
          control over financial reporting that occurred during the registrant's
          most recent fiscal quarter that has materially affected, or is
          reasonably likely to materially affect, the registrant's internal
          control over financial reporting; and

5.   The registrant's other certifying officer(s) and I have disclosed to the
     registrant's auditors and the audit committee of the registrant's board of
     directors (or persons performing the equivalent functions):

     (a)  All significant deficiencies and material weaknesses in the design or
          operation of internal control over financial reporting which are
          reasonably likely to adversely affect the registrant's ability to
          record, process, summarize, and report financial information; and

     (b)  Any fraud, whether or not material, that involves management or other
          employees who have a significant role in the registrant's internal
          control over financial reporting.
