                                                FOR IMMEDIATE RELEASE



                                EATON VANCE CORP.
                REPORT FOR THE THREE MONTHS AND SIX MONTHS ENDED
                                 APRIL 30, 2005


BOSTON,  MA--Eaton Vance Corp.  reported  diluted earnings per share of $0.27 in
the second  quarter of fiscal  2005  compared to diluted  earnings  per share of
$0.25 in the second  quarter of fiscal  2004,  an increase  of 8 percent.  Eaton
Vance earned $0.53 per diluted  share in the first six months of fiscal 2005, an
increase of 15 percent  compared  to earnings of $0.46 per diluted  share in the
first six months of fiscal 2004.

Assets under  management  of $98.8  billion at the end of the second  quarter of
fiscal 2005 were $13.7  billion or 16 percent  greater than the $85.1 billion at
the end of the second  fiscal  quarter last year.  In the 12-month  period ended
April 30, 2005, the Company's assets under  management were positively  affected
by long-term fund and separate account net inflows of $9.3 billion, market price
appreciation of $2.6 billion and $1.9 billion of separate accounts acquired from
Deutsche  Bank in July 2004.  Gross  sales and  inflows of  long-term  funds and
separate  accounts in the last 12 months were $24.0 billion,  including five new
closed-end funds that raised a total of $3.8 billion.

Fund and separate  account net inflows of $2.1 billion in the second  quarter of
fiscal 2005  compared to net  inflows of $2.3  billion in the second  quarter of
fiscal 2004. This year's second quarter net inflows included $1.0 billion raised
in two closed-end fund offerings:  Eaton Vance Short Duration Diversified Income
Fund offered in February,  Eaton Vance Tax-Managed Buy-Write Income Fund offered
in April and the  over-allotment  shares from Eaton Vance Enhanced Equity Income
Fund II offered in January. Last year's second quarter benefited from closed-end
fund  inflows of $1.1  billion  that  included  the  offering of Eaton Vance Tax
Advantaged Global Dividend  Opportunities Fund and the over-allotment common and
preferred  shares related to Eaton Vance  Tax-Advantaged  Global Dividend Income
Fund offered in January 2004.  Excluding  closed-end  funds, net flows for Eaton
Vance funds were $0.9 billion in the second  quarter of fiscal 2005  compared to
$0.7 billion in the second quarter of fiscal 2004.

                                  Page 5 of 10

The Company  experienced  institutional and high-net-worth  separate account net
outflows of $0.4  billion in the second  quarter of fiscal 2005  compared to net
inflows of $0.3 billion in the second quarter of fiscal 2004,  primarily because
of  management  turnover at a subsidiary  and portfolio  rebalancing  by certain
institutional clients. Retail managed account net inflows, however, increased by
over 200 percent to $0.5 billion in the second  quarter of fiscal 2005  compared
to the same period last year.  Tables 1-4  (attached)  provide  more  details on
assets under management and asset flows.

As a result of higher  average  assets under  management,  revenue in the second
quarter  of fiscal  2005  increased  by $17.2  million  or 10  percent to $182.5
million  compared  to  revenue in the  second  quarter of fiscal  2004 of $165.3
million.  Investment  adviser and  administration  fees  increased 20 percent to
$121.4  million,  compared to the 17 percent  increase in average  assets  under
management.  Distribution and underwriter fees decreased 15 percent,  reflecting
the  continuing  shift in sales and assets  from class B mutual  fund  shares to
other fund share  classes and other managed  assets with low or no  distribution
fees.  Service  fee revenue  increased 9 percent due to the  increase in average
fund assets that pay these fees. Other revenue increased 49 percent primarily as
a result of investment income earned by two consolidated investment companies.

Operating  expenses increased 11 percent in the second quarter of fiscal 2005 to
$121.1  million  compared to operating  expenses of $109.1 million in the second
quarter  of  fiscal  2004,   because  of  higher   compensation,   service  fee,
distribution  and other  expenses.  Compensation  expense  increased  19 percent
because of increases in employee headcount, separately managed account incentive
compensation and higher operating income-based bonus accruals.

Amortization  of deferred  sales  commissions  declined 23 percent in the second
quarter of fiscal 2005 compared to the second  quarter of fiscal 2004  primarily
because  of the  continuing  decline  in class B share  sales and  assets  under
management.  Service fee expense increased 9 percent,  in line with the increase
in service fee revenue. Distribution expense increased 18 percent as a result of
increases  in class C share fund  distribution  fees and  closed-end  fund fees.
Other expense  increased 38 percent  primarily  because of higher fund expenses,
facilities,  information technology,  legal, audit,  compliance,  recruiting and
other miscellaneous expenses.

Operating income increased 9 percent to $61.5 million and net income increased 7
percent to $37.6 million in the second quarter of fiscal 2005, compared to $56.2
million and $35.2 million,  respectively,  in the second quarter of fiscal 2004.
Interest  income  increased 60 percent because of higher interest earned on cash
and  short-term  investments.  Interest  expense  decreased  $1.0  million or 73
percent,  reflecting a $44.7 million  reduction in long-term  debt.  The Company
recognized a $1.8 million impairment loss on its equity in a collateralized debt
obligation  fund on April 30, 2005.  The Company's  effective  tax rate,  before
minority  interest and equity in net income of  affiliates,  was 36.3 percent in
the second  quarter  of fiscal  2005 and 35.3  percent in the second  quarter of
fiscal 2004.

Cash, cash  equivalents and short-term  investments were $284.8 million on April
30, 2005, and $308.3 million,  including  $47.1 million of minority  shareholder
investments  in a  consolidated  investment  company on April 30, 2004. In April
2005,  because of the  fund's  overall  growth,  the  Company  became a minority
investor  in  the  Eaton   Vance   Short-Term   Income  Fund  and   discontinued
consolidating the fund in its financial statements.

                                  Page 6 of 10

The Company's  strong  operating  cash flow in the last 12 months  allowed it to
reduce its  long-term  debt by $44.7  million to $74.9  million and to pay $77.8
million in income taxes, $51.1 million in sales  commissions,  $115.3 million to
repurchase 5.2 million  shares of its non-voting  common stock and $39.4 million
in dividends to  shareholders.  There are  currently no  outstanding  borrowings
against the Company's $180 million credit facility.

During the first six months of fiscal 2005, the Company  repurchased and retired
2,982,077  shares of its  non-voting  common stock at an average price of $24.53
per share under its current and prior repurchase  authorizations.  Approximately
7.7 million shares remain of the current 8.0 million share authorization.
