Gentlemen:
You have requested our opinion regarding certain Federal income tax
consequences to American Century-Benham Intermediate-Term Government Fund (the
"Fund"), a portfolio of American Century Mutual Funds, Inc., to American
Century-Benham Intermediate-Term Treasury Fund ("Acquiring"), a portfolio of
American Century Government Income Trust, and to the holders of the shares of
common stock of the Fund, in connection with the proposed transfer of
substantially all of the properties of the Fund to Acquiring, in exchange solely
for voting shares of beneficial interest of Acquiring ("Acquiring Shares") and
the assumption by Acquiring of all of the liabilities of the Fund followed by
the distribution of such Acquiring Shares received by the Fund in complete
liquidation and termination of the Fund, all pursuant to the Agreement and Plan
of Reorganization (the "Agreement") executed by the Fund and Acquiring and
included as an exhibit to Form N-14.
For purposes of this opinion, we have examined and relied upon (1) the
Agreement, (2) the Form N-14, dated June 2, 1997, and filed by Acquiring on
April 21, 1997, with the Securities and Exchange Commission, (3) letters of
representation furnished to us by Fund and Acquiring,

and (4) such other documents and instruments as we have deemed necessary or
appropriate for purposes of rendering this opinion. We assume that the
transaction that is the subject of this letter will be carried out in accordance
with the terms of the Agreement and as described in the documents we have
examined. This opinion is based upon the Internal Revenue Code of 1986, as
amended (the "Code"), United States Treasury regulations, judicial decisions,
and administrative rulings and pronouncements of the Internal Revenue Service,
all as in effect on the date hereof.
Based upon the foregoing, it is our opinion that, for Federal income
tax purposes:
(1) The acquisition by Acquiring of substantially all of the properties
of the Fund in exchange solely for Acquiring Shares and the assumption by
Acquiring of the liabilities of the Fund followed by the distribution of
Acquiring Shares to the shareholders of the Fund in exchange for their Fund
shares in complete liquidation and termination of the Fund, will constitute a
reorganization within the meaning of Section 368 of the Code. The Fund and
Acquiring will each be "a party to a reorganization" within the meaning of
Section 368(b) of the Code.
(2) The Fund will recognize no gain or loss upon transferring its
properties to Acquiring in exchange solely for Acquiring Shares and the
assumption by Acquiring of the liabilities of the Fund or upon distributing to
its shareholders the Acquiring Shares received by the Fund in the transaction
pursuant to the Agreement.
(3) Acquiring will recognize no gain or loss upon receiving the
properties of the Fund in exchange for Acquiring Shares and the assumption by
Acquiring of the liabilities of the Fund.
(4) The aggregate adjusted basis to Acquiring of the properties of the
Fund will be the same as the aggregate adjusted basis of those properties in the
hands of the Fund immediately before the exchange.
(5) Acquiring's holding periods with respect to the properties of the
Fund that Acquiring acquires in the transaction will include the respective
periods for which those properties were held by the Fund (except where
investment activities of Acquiring have the

effect of reducing or eliminating a holding period with respect to an asset).
(6) The shareholders of the Fund will recognize no gain or loss upon
receiving Acquiring Shares solely in exchange for Fund shares.
(7) The aggregate basis of the Acquiring Shares received by a
shareholder of the Fund in the transaction will be the same as the aggregate
basis of the Fund shares surrendered by the shareholder in exchange therefor.
(8) A Fund shareholder's holding period for the Acquiring Shares
received by the shareholder in the transaction will include the holding period
during which the shareholder held the Fund shares surrendered in exchange
therefor, provided that the shareholder held such shares as a capital asset on
the date of Reorganization.
We express no opinion as to the tax consequences of the Reorganization
except as expressly set forth above, or as to any transaction except those
consummated in accordance with the Agreement and the representations to be made
to us.
We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement on Form N-14 filed by Acquiring with the Securities and
Exchange Commission.
