Delaware  Investments  Colorado Insured Municipal Income Fund, Inc. and Delaware
Investments  Florida Insured  Municipal  Income Fund Adjourn Annual  Shareholder
Meeting  with  Respect to Proposals  to Change  Certain  Fundamental  Investment
Policies

PHILADELPHIA,  August 15, 2007 - Delaware Investments Colorado Insured Municipal
Income Fund, Inc. (ASE: VCF) and Delaware  Investments Florida Insured Municipal
Income Fund (ASE:  VFL) (each, a "Fund") today  announced the adjournment of the
Annual Meeting of Shareholders (the "Annual Meeting") until Thursday,  September
13, 2007 at 3:00 p.m.,  local time,  at which time it will be  reconvened at the
offices of Delaware  Investments,  One Commerce Square, 2005 Market Street, 30th
Floor Board Room, Philadelphia, PA. The Annual Meeting was adjourned to give the
Funds  additional  time to  solicit  proxies  for  proposals  to change  certain
fundamental investment policies for each Fund.

Delaware Investments Colorado Insured Municipal Income Fund, Inc.

Shareholders of Delaware  Investments  Colorado  Insured  Municipal Income Fund,
Inc.  (the "CO  Fund")  are being  asked to vote on a proposal  to  eliminate  a
fundamental  investment  policy  requiring  the CO Fund to invest  primarily  in
insured Colorado municipal  securities rated AAA, and permitting the CO Fund, as
a non-fundamental  investment policy, to invest without limitation in uninsured,
investment  grade Colorado  municipal  securities  (including  those rated below
AAA). If these changes to the fundamental investment policy are approved, the CO
Fund may invest up to 20% of its net  assets in  non-investment  grade  Colorado
municipal  securities as a  non-fundamental  investment  policy. If the proposed
changes are approved by  shareholders,  the CO Fund will be renamed the Delaware
Investments  Colorado  Municipal  Income Fund,  Inc.,  consistent  with its new,
uninsured investment strategy.

If these  changes are  approved by the CO Fund's  shareholders,  the  investment
objective  of the CO Fund,  which is  non-fundamental,  will  continue  to be to
provide current income exempt from regular federal income tax and Colorado state
income  tax,   consistent  with  the  preservation  of  capital.   Under  normal
circumstances,  the CO Fund  will  invest  at  least  80% of its net  assets  in
investment grade quality  Colorado  municipal bonds. The CO Fund will be able to
invest up to 20% of its net  assets  in  municipal  obligations  issued by or on
behalf of  territories  of the  United  States - such as Guam,  the U.S.  Virgin
Islands or Puerto Rico - that are exempt from  Colorado and federal  income tax,
subject to the CO Fund's fundamental  investment policy to invest 80% of its net
assets in Colorado municipal obligations. Additionally, the CO Fund will be able
to invest up to 20% of its net  assets in  municipal  bonds  with an  investment
rating of Ba/BB or lower,  or that are  unrated  but judged to be of  comparable
quality by the CO Fund's  investment  adviser.  Investment in municipal bonds of
below   investment  grade  quality  involves  special  risks  as  compared  with
investment in higher grade

municipal bonds.  These risks include greater  sensitivity to economic downturns
in Colorado or in the United States generally. Securities rated below investment
grade are  commonly  known as "junk  bonds."  Such  securities  are  regarded as
predominantly  speculative  with respect to the issuer's ability to pay interest
and repay principal owed.

The  management  of the CO Fund  believe that  permitting  the CO Fund to invest
without  limitation in investment  grade Colorado  municipal  securities  (those
rated BBB or above)  and up to 20% of its net  assets  in  non-investment  grade
municipal  securities will allow the portfolio managers and research analysts to
take greater  advantage of  investment  opportunities  that may generate  higher
current  yield for the CO Fund's  shareholders.  The  management  of the CO Fund
believe  that  broadening  the CO Fund's  authority  to invest in this area will
improve the portfolio managers'  flexibility in meeting the CO Fund's investment
objective.

Delaware Investments Florida Insured Municipal Income Fund

Florida repealed its intangible personal property tax effective January 1, 2007,
and  it  has  no  state  income  tax.  As a  result,  the  continued  appeal  of
Florida-only  municipal debt funds is limited,  as municipal bonds issued by the
state of Florida no longer provide a specific tax advantage to Florida residents
over municipal securities of extrastate issuers.

Shareholders of Delaware  Investments Florida Insured Municipal Income Fund (the
"FL Fund")  are  therefore  being  asked to vote on a proposal  to  eliminate  a
fundamental  investment  policy  requiring  the FL Fund to invest 80% of its net
assets in insured,  AAA-rated municipal bonds issued by the State of Florida. If
these changes to the  fundamental  investment  policy are approved,  the FL Fund
may, as a non-fundamental  policy,  (1) invest without limitation in un-insured,
investment  grade municipal  securities of states other than Florida  (including
those  rated  below  AAA)  and  (2)  invest  up to  20%  of its  net  assets  in
non-investment grade municipal securities.  If the proposed changes are approved
by shareholders,  the FL Fund will be renamed the Delaware  Investments National
Municipal Income Fund, consistent with its new, national investment strategy.

If these  changes  are  approved  by the FL Fund's  shareholders,  the FL Fund's
investment  objective,  which is  non-fundamental,  will be  changed  to provide
current  income  exempt from regular  federal  income tax,  consistent  with the
preservation of capital. As a fundamental policy, under normal circumstances the
FL Fund will invest at least 80% of its net assets in securities the income from
which is exempt from federal income taxes. The FL Fund will be able to invest up
to 20% of its net assets in municipal  bonds with an investment  rating of Ba/BB
or lower,  or that are unrated but judged to be of comparable  quality by the FL
Fund's  investment  adviser.  Investment in municipal bonds of below  investment
grade quality involves special risks as compared with investment in higher grade
municipal  bonds.  These risks include greater  sensitivity to general  economic
downturns.  Securities  rated below investment grade are commonly known as "junk
bonds." Such securities are regarded as  predominantly  speculative with respect
to the issuer's ability to pay interest and repay principal owed.

It is  anticipated  that the FL Fund will  transition its portfolio over time to
include  municipal  bonds  from  other  states  and  territories.   During  that
transition  period,  the FL Fund may have  significant  investments  in  Florida
municipal  bonds.  This  could  make  the FL Fund  more  sensitive  to  economic
conditions  in  Florida  than  other more  geographically  diversified  national
municipal income funds.

Shareholders  of the FL Fund could  benefit from the  increased  diversification
offered by a national  municipal  bond fund without a single-state  mandate.  By
converting the FL Fund into a national  fund,  investors of the FL Fund would be
exposed to less  geographical  risk, and, as discussed above,  Florida municipal
securities  no longer  offer unique tax  benefits to Florida  residents.  The FL
Fund's  management also believes that  shareholders of the FL Fund would benefit
from the  increased  diversification  offered  by a  municipal  securities  fund
without an insured mandate. In addition, management believes that permitting the
FL Fund to invest without  limitation in investment  grade municipal  securities
(those  rated BBB and above)  and up to 20% of its net assets in  non-investment
grade  municipal  securities  (those rated below BBB) will improve the portfolio
managers' flexibility in meeting the FL Fund's investment objective.
