DEAR SHAREHOLDER,

We present you with the annual report for Investment Grade Municipal Income Fund
Inc. for the fiscal year ended September 30, 2002.

AN INTERVIEW WITH PORTFOLIO MANAGER WILLIAM VERONDA

Q: HOW DID THE FUND PERFORM DURING THE PERIOD RELATIVE TO ITS PEERS?

A: For the fiscal year ended September 30, 2002, the Fund's net asset value grew
   8.21% and its market price increased 7.96%, underperforming its competitors
   as measured by the Lipper General Municipal Debt Fund (Leveraged) Median. The
   Lipper Median's net asset value and market price rose 10.58% and 12.75%,
   respectively. The Fund's shorter average duration compared to its peers was
   the primary contributor to its underperformance versus the benchmark. (For
   more on the Fund's performance, refer to "Performance At A Glance" on page
   4.)

Q: COULD YOU DESCRIBE THE ECONOMIC ENVIRONMENT DURING THE PERIOD?

A: The reporting period began shortly after the September 11 terrorist attacks.
   At that time, prospects for a rapid economic recovery were unlikely. However,
   the Federal Reserve Board (the "Fed") moved quickly to stabilize the economy
   and add liquidity to the financial system. All told, from October 2001
   through December 2001, the Fed cut the Fed Funds rate (the rate U.S. banks
   charge each other for overnight loans) three times, down to 1.75%--its lowest
   level in several decades. Following a quick renewal in consumer spending,
   gross domestic product (GDP) rose a surprising 2.7% during the fourth quarter
   of 2001. As increasing signs of economic growth emerged during the first
   quarter of 2002, the Fed shifted its bias from one of easing to combat
   economic weakness, to one of neutrality. The change in policy appeared
   warranted, as the GDP ultimately accelerated to a 5.0% growth rate during
   this period. However, the uptick proved short-lived. Ongoing threats of
   terrorism, turmoil in the Middle East, anemic corporate spending, waning
   consumer confidence in light of the stock market's decline, and corporate
   accounting scandals all took their toll. The end result: second quarter 2002
   GDP growth was a less-

   than-expected 1.3%. Although the third quarter figure came in at 4.0%, as of
   this writing investors were already focusing on fourth quarter GDP, since it
   may be an indicator as to whether a sustainable economic recovery is likely.

Q: HOW DID THE BOND MARKET PERFORM DURING THE ONE-YEAR PERIOD?

A: Given the uncertainties regarding the economy, the weak stock market, and
   geopolitical concerns, the bond market rallied sharply during the period.
   Investors were drawn to the relative safety and strong performance offered by
   fixed income securities in general, and the municipal market participated in
   this upswing.

Q: WHILE THE FUND GENERATED STRONG ABSOLUTE RETURNS, IT LAGGED ITS BENCHMARK
   DURING THE PERIOD. WHAT WAS THE PRIMARY REASON FOR THE FUND'S RELATIVE
   UNDERPERFORMANCE?

A: To some extent, our goal of limiting the Fund's capital gains adversely
   affected its results during the period. Based on the municipal market's
   strong performance in recent years, nearly every security in the portfolio
   has risen in price. In an effort to limit locking in capital gains, we've
   tended to hold on to our positions. Consequently, many of the bonds in the
   Fund's portfolio have "aged" to the point where they have short maturities.
   With a shorter duration than the benchmark, the Fund underperformed its peers
   in the falling interest rate environment.

Q: HOW ARE YOU CURRENTLY POSITIONING THE FUND'S PORTFOLIO?

A: We are continuing to selectively focus on bonds that have longer durations,
   typically those with maturities that more accurately reflect the municipal
   market as a whole. This positioning has increased the Fund's flexibility to
   purchase what we believe are attractively structured and priced municipal
   securities. In particular, we're focusing on bonds with maturities in the 15-
   to 20-year range, as we believe these issues offer a "sweet spot" in terms of
   their risk/reward characteristics: while we give up a little bit of yield
   versus 30-year issues, 15- to 20-year bonds are less volatile than their
   longer-term counterparts.

Q: TO ILLUSTRATE YOUR INVESTMENT STRATEGY, PLEASE DESCRIBE SOME HOLDINGS THAT
   YOU BOUGHT OR SOLD DURING THIS REPORTING PERIOD?

A: We purchased a block of bonds from the Triborough Bridge and Tunnel Authority
   of New York that matures in 2022 and provides an attractive 5% coupon. These
   types of issues tend to have a high degree of stability. We sold out of our
   position in a small college in California, since it no longer lived up to our
   expectations. In particular, we were concerned over its deteriorating credit
   quality due to declining enrollments at the college.

Investment Grade Municipal Income Fund Inc.


Q: WERE THERE ANY SECTORS OF THE MARKET THAT YOU FOCUSED ON?

A: The Fund's portfolio tends to be highly diversified. When an overweight of a
   particular sector occurs, it is due to the fact that we view it as being
   highly attractive.

Q: LASTLY, WHAT IS YOUR SHORT-TERM AND LONG-TERM OUTLOOK FOR THE MARKET?

A: We believe a modest economic expansion will take hold and that a double-dip
   recession--while possible--is unlikely. Given a subdued growth rate, we feel
   that interest rates will remain in a trading range--a change from the falling
   rate environment we've seen in the past few years. As such, we anticipate
   continuing our strategy of emphasizing longer-term securities at attractive
   points on the yield curve. We will also continue to stress credit quality in
   the portfolio to avoid any "contagion" from weakness in the corporate bond
   markets.

Our ultimate objective in managing your investments is to help you successfully
meet your financial goals. We thank you for your continued support and welcome
any comments or questions you may have. For additional information on the UBS

ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

Investment  Grade  Municipal  Income Fund Inc. (the "Fund") was  incorporated in
Maryland on August 6, 1992,  and is registered  with the Securities and Exchange
Commission under the Investment Company Act of 1940, as amended, as a closed-end
diversified management investment company. The Fund's investment objective is to
achieve a high level of current  income that is exempt from federal  income tax,
consistent with the preservation of capital.

The preparation of financial statements in accordance with accounting principles
generally  accepted  in the  United  States  requires  Fund  management  to make
estimates and  assumptions  that affect the reported  amounts and disclosures in
the financial statements.  Actual results could differ from those estimates. The
following is a summary of significant accounting policies:

VALUATION OF  INVESTMENTS--The  Fund calculates its net asset value based on the
current market value, where available,  for its portfolio  securities.  The Fund
normally  obtains  market values for its  securities  from  independent  pricing
sources and  broker-dealers.  Independent  pricing sources may use reported last
sale prices,  current market quotations or valuations from computerized "matrix"
systems that derive values based on comparable securities.  If a market value is
not available from an independent pricing source for a particular security, that
security  is valued at fair  value as  determined  in good faith by or under the
direction of the Fund's board of directors  (the  "Board").  The amortized  cost
method of valuation, which approximates market value, generally is used to value
short-term  debt  instruments  with sixty days or less  remaining  to  maturity,
unless the Board determines that this does not represent fair value.

INVESTMENT  TRANSACTIONS  AND  INVESTMENT  INCOME--Investment  transactions  are
recorded  on  the  trade  date.   Realized  gains  and  losses  from  investment
transactions are calculated using the identified cost method. Interest income is
recorded on an accrual basis.  Discounts are accreted and premiums are amortized
as adjustments to interest income and the identified cost of investments.

DIVIDENDS AND DISTRIBUTIONS--The Fund intends to pay monthly dividends to common
shareholders  at a level rate that over time will result in the  distribution of
all of the Fund's net investment income remaining after the payment of dividends
on any outstanding  preferred  shares.  The dividend rate on the common stock is
adjusted as  necessary to reflect the  performance  of the Fund.  Dividends  and
distributions  to common  shareholders  are  recorded on the  ex-dividend  date.
Dividends to preferred  shareholders  are accrued daily. The amount of dividends
from net investment income and distributions  from net realized capital gains is
determined in accordance with federal income tax  regulations,  which may differ
from  accounting  principles  generally  accepted  in the United  States.  These
"book/tax"  differences are either considered  temporary or permanent in nature.
To the extent  these  differences  are  permanent  in nature,  such  amounts are
reclassified  within  the  capital  accounts  based on their  federal  tax-basis
treatment; temporary differences do not require reclassification.

CHANGE IN ACCOUNTING PRINCIPLE

Effective as of October 1, 2000, the Fund adopted the classification requirement
of EITF D-98, CLASSIFICATION AND MEASUREMENT OF REDEEMABLE SECURITIES. EITF D-98
requires  that  preferred  shares for which  redemption is outside of the Fund's
control should be presented outside of net assets applicable to common shares in
the statement of assets and  liabilities.  The  redemption of the Fund's auction
preferred  shares  is  outside  of the  control  of the  Fund  because  they are
redeemable upon the occurrence of an event that is not solely within the control
of the Fund. In adopting EITF D-98,  the Fund's net assets as of October 1, 2000
in the statement of changes in net assets  applicable to common  shareholders is
restated by excluding  auction  preferred  shares valued at  $80,000,000 at that
date. The adoption also resulted in dividends on auction  preferred shares being
reclassified  from  distributions  on the  statement  of  changes  in net assets
applicable to common  shareholders  to a separate line item within the statement
of operations.  This resulted in a decrease of $3,045,659 in the net increase in
net assets applicable to common  shareholders  resulting from operations for the
year ended September 30, 2001. As part of the adoption,  per share distributions
of  dividends  on auction  preferred  shares,  if any,  were  reclassified  from
distributions to amounts from investment operations for each period presented in
the financial highlights.

CONCENTRATION OF RISK

The Fund  follows an  investment  policy of  investing  primarily  in  municipal
obligations  of various  states.  Economic  changes  affecting  those states and
certain of their public bodies and  municipalities may affect the ability of the
issuers within those states to pay interest on, or repay principal of, municipal
obligations held by the Fund.

INVESTMENT ADVISOR AND ADMINISTRATOR

The Board has  approved  an  investment  advisory  and  administration  contract
("Advisory  Contract")  with UBS Global Asset  Management (US) Inc. ("UBS Global
AM"), under which UBS Global AM serves as investment  advisor and  administrator
of the  Fund.  UBS  Global  AM is an  indirect  wholly  owned  asset  management
subsidiary  of  UBS  AG,  an  internationally   diversified   organization  with
headquarters  in  Zurich,  Switzerland  and  operations  in  many  areas  of the
financial services industry. In accordance with the Advisory Contract,  the Fund
pays UBS Global AM an  investment  advisory  and  administration  fee,  which is
accrued  weekly  and paid  monthly,  at the  annual  rate of 0.90% of the Fund's
average weekly net assets.  For the year ended September 30, 2002, UBS Global AM
voluntarily waived $307,723 in investment  advisory and administration fees from
the Fund.

COMMON STOCK

There are  199,998,400  shares of $0.001 par value common stock  authorized  and
10,356,667 common shares outstanding at September 30, 2002.

AUCTION PREFERRED SHARES

The Fund has  issued 800 shares of  Auction  Preferred  Shares  Series A and 800
shares of  Auction  Preferred  Shares  Series B,  which are  referred  to herein
collectively  as the "APS." All shares of each series of APS have a  liquidation
preference of $50,000 per share plus an amount equal to  accumulated  but unpaid
dividends upon liquidation.

Dividends,  which are  cumulative,  are  generally  reset  every 28 days for APS
Series A and 90 days for APS Series B.  Dividend  rates  ranged  from  1.249% to
2.300% for the year ended  September  30,  2002.  The Fund is subject to certain
restrictions  relating  to the APS.  Failure to comply  with these  restrictions
could preclude the Fund from declaring any distributions to common  shareholders
or repurchasing  common shares and/or could trigger the mandatory  redemption of
APS at liquidation value.

The APS are  entitled to one vote per share and,  unless  otherwise  required by
law, will vote with holders of common stock as a single  class,  except that the
preferred shares will vote separately as a class on certain matters, as required
by law.  The  holders  of the  preferred  shares  have the  right  to elect  two
directors of the Fund.

FEDERAL TAX STATUS

For federal income tax purposes,  the components of net unrealized  appreciation
of investments at September 30, 2002 were as follows:

Gross appreciation (investments having an excess of value
  over cost) ....................................................  $13,049,042
Gross depreciation (investments having an excess of cost
  over value) ...................................................     (234,332)
                                                                   -----------
Net unrealized appreciation of investments ......................  $12,814,710
                                                                   ===========

For the year ended September 30, 2002,  total  aggregate  purchases and sales of
portfolio  securities,  excluding  short-term  securities,  were $49,724,763 and
$61,189,897,  respectively.  The Fund intends to distribute substantially all of
its  tax-exempt  income  and any  taxable  income  and to comply  with the other
requirements  of the Internal  Revenue Code  applicable to regulated  investment
companies.  Accordingly,  no provision for federal income taxes is required.  In
addition, by distributing during each calendar year substantially all of its net
investment income, net realized capital gains and certain other amounts, if any,
the Fund intends not to be subject to a federal excise tax.

The tax character of distributions  paid during the fiscal years ended September
30, 2002 and September 30, 2001 were as follows:

Distributions paid from:                                  2002           2001
                                                         -----          -----
Tax-exempt income ...............................  $10,887,019    $11,870,353
Net long-term capital gains .....................      436,163      2,501,294
                                                   -----------    -----------
Total Distributions .............................  $11,323,182    $14,371,647

Notes to Financial Statements



FEDERAL TAX STATUS (CONCLUDED)

Total  distributions  paid  differ from the  statement  of changes in net assets
applicable  to  common  shareholders  because  for tax  purposes  dividends  are
recognized when actually paid.

At  September  30,  2002,  the components of accumulated earnings on a tax basis
were as follows:

Undistributed tax-exempt income ..................  $1,938,071
Undistributed long-term capital gains ............   2,096,474
                                                   -----------
Accumulated earnings .............................   4,034,545
Net unrealized appreciation of investments .......  12,814,710
                                                   -----------
Total accumulated earnings ....................... $16,849,255
                                                   ===========

To reflect  reclassifications  arising from permanent "book/tax" differences for
the year ended  September  30, 2002,  the Fund's  undistributed  net  investment
income was decreased by $607 and  accumulated  net realized gains were increased
by $607.

Report of Ernst & Young LLP, Independent Auditors


To the Board of Directors and Shareholders of
Investment Grade Municipal Income Fund Inc.

We have  audited  the  accompanying  statement  of  assets  and  liabilities  of
Investment  Grade  Municipal  Income  Fund  Inc.  (the  "Fund"),  including  the
portfolio of  investments  as of September  30, 2002,  the related  statement of
operations  for the year then ended,  and the statement of changes in net assets
applicable to common  shareholders and the financial  highlights for each of the
two years in the period then ended.  These  financial  statements  and financial
highlights are the responsibility of the Fund's  management.  Our responsibility
is to express an opinion on these financial  statements and financial highlights
based on our audits. The financial highlights for each of the three years in the
period ended  September 30, 2000,  were audited by other  auditors  whose report
dated  November 22, 2000,  expressed an unqualified  opinion on those  financial
highlights.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain  reasonable  assurance  about  whether the  financial  statements  and
financial  highlights  are free of  material  misstatement.  An  audit  includes
examining,  on a test basis,  evidence supporting the amounts and disclosures in
the financial  statements  and financial  highlights.  Our  procedures  included
confirmation of securities  owned at September 30, 2002 by  correspondence  with
the custodian  and brokers.  An audit also  includes  assessing  the  accounting
principles  used  and  significant  estimates  made  by  management,  as well as
evaluating the overall  financial  statement  presentation.  We believe that our
audits provide a reasonable basis for our opinion.

In our opinion,  the financial  statements and financial  highlights referred to
above and audited by us, present fairly, in all material respects, the financial
position of Investment  Grade Municipal  Income Fund Inc. at September 30, 2002,
and the results of its operations for the year then ended and the changes in its
net assets  applicable to common  shareholders and the financial  highlights for
each of the two years in the period then ended,  in conformity  with  accounting
principles generally accepted in the United States. As discussed in the Notes to
Financial  Statements,  effective  as of  October 1, 2000 the Fund  changed  its
method  of  classifying  its  auction  preferred  shares  and its  dividends  to
preferred shareholders on such auction preferred shares.

TAX INFORMATION (UNAUDITED)

We are  required  by  Subchapter  M of the  Internal  Revenue  Code of 1986,  as
amended,  to advise you within 60 days of the Fund's fiscal year end  (September
30, 2002) as to the federal tax status of distributions received by stockholders
during  such  fiscal  year.  Accordingly,  we are  advising  you that,  with the
exception  of a  net  long-term  capital  gain  distribution  of  $436,163,  net
investment  income  distributions  of  $10,887,019  paid  during the fiscal year
qualified as federal tax-exempt interest dividends.

The Fund did not invest in any  securities  which paid  interest  subject to the
federal alternative minimum tax for individual taxpayers during its fiscal year.
Therefore, none of the dividends paid by the Fund were subject to such tax.

Because the Fund's fiscal year is not the calendar  year,  another  notification
will be sent in respect of calendar year 2002.  The second  notification,  which
reflects  the amount to be used by  calendar  year  taxpayers  on their  federal
income tax returns,  will be made in conjunction  with Form 1099 DIV and will be
mailed in January  2003.  Stockholders  are  advised  to  consult  their own tax
advisors with respect to the tax consequences of their investment in the Fund.

GENERAL INFORMATION (UNAUDITED)

THE FUND

Investment  Grade  Municipal  Income Fund Inc.  (the  "Fund") is a  diversified,
closed-end management investment company whose shares trade on the New YorkStock
Exchange  ("NYSE").The Fund's investment objective is to achieve a high level of
current  income that is exempt from  federal  income  tax,  consistent  with the
preservation of capital.  The Fund's investment advisor and administrator is UBS
Global Asset  Management  (US) Inc. ("UBS Global AM"), an indirect  wholly owned
asset  management  subsidiary  of UBS AG, which has over $71.4 billion in assets
under management as of October 31, 2002.

Effective May 20, 2002,  William Veronda assumed primary  responsibility for the
day-to-day  management  of the Fund.  Mr.  Veronda is an Executive  Director and
portfolio  manager  of UBS  Global  AM.  Mr.  Veronda  joined  UBS  Global AM in
September  1995 and has led its municipal  research  group since that date.  Mr.
Veronda  previously  served as the portfolio  manager for PaineWebber  Municipal
High Income Fund from September 1995 until March 2001.

INVESTMENT POLICY CHANGES

The Fund's board approved  modifications to the Fund's investment  policies as a
result of a new rule promulgated by the Securities and Exchange Commission. This
rule  generally  requires  a fund with a name  suggesting  that it  focuses on a
particular type of

GENERAL INFORMATION (UNAUDITED) (CONTINUED)

INVESTMENT POLICY CHANGES (CONTINUED)
investment  to  invest at least 80% of its net  assets  (plus the  amount of any
borrowing for  investment  purposes) in the type of investment  suggested by its
name. The investment  policy  changes became  effective on April 8, 2002.  These
changes are not expected to affect materially portfolio management.

The new 80% policy has been adopted as a "fundamental"  investment  policy;  the
Fund may not deviate from this 80% policy without shareholder approval.  Many of
the Fund's other  investment  policies are  non-fundamental  policies and may be
changed by its board without shareholder approval. The Fund will interpret these
new policies as if the following  phrase  appeared  immediately  after the words
"net assets":  "(plus the amount of any borrowing for investment  purposes)." If
subsequent to an investment, the Fund's 80% policy is no longer met (E.G., bonds
are  called   resulting  in  a  large   influx  of  cash),   then  under  normal
circumstances,  the Fund's  future  investments  would be made in a manner  that
would bring the Fund's investments back in line with the 80% threshold.

In order to place these changes in context,  reproduced below are prior policies
that were  impacted by this  change as well as new  policies  which  replace the
prior policies:

PRIOR POLICIES IMPACTED BY CHANGE:

         The  Fund  normally  invests  substantially  all  of  its  assets  in a
         diversified  portfolio of long-term  tax-exempt  Municipal  Obligations
         that have been  rated  investment  grade or are  unrated  but have been
         determined  to be of  comparable  quality by UBS  Global AM.  Municipal
         Obligations  rated  investment  grade  are those  that,  at the time of
         investment, are rated within the four highest grades by Moody's (Baa or
         higher)  or S&P  (BBB or  higher)  or have an  equivalent  rating  from
         another nationally recognized statistical rating organization. The Fund
         may invest up to 20% of its total assets in Municipal  Obligations that
         are unrated but that, at the time of investment,  have been  determined
         by UBS  Global AM to be of  comparable  quality to those that are rated
         investment grade. Under normal circumstances, the Fund invests at least
         65% of its total assets in income-producing securities.

INVESTMENT POLICY CHANGES (CONCLUDED)

REVISED POLICIES:

         The  Fund  normally  invests  substantially  all  of  its  assets  in a
         diversified portfolio of long-term Municipal Obligations.  Under normal
         circumstances,  the Fund  invests  at least  80% of its net  assets  in
         investment grade Municipal Obligations, the income from which is exempt
         from regular federal income tax. Municipal Obligations rated investment
         grade are those that, at the time of  investment,  are rated within the
         four  highest  grades by Moody's (Baa or higher) or S&P (BBB or higher)
         or  have  an  equivalent  rating  from  another  nationally  recognized
         statistical rating  organization.  The Fund may invest up to 20% of its
         net assets in Municipal  Obligations  that are unrated but that, at the
         time of  investment,  have been  determined  by UBS  Global AM to be of
         comparable quality to those that are rated investment grade.

SHAREHOLDER INFORMATION

The Fund's NYSE trading symbol is "PPM."  Comparative net asset value and market
price information about the Fund is published weekly in THE WALLSTREET  JOURNAL,
THE NEW YORK TIMES and BARRON'S, as well as in numerous other publications.

DIVIDEND REINVESTMENT PLAN

The Fund's Board has established a Dividend Reinvestment Plan (the "Plan") under
which all common shareholders whose shares are registered in their own names, or
in the name of UBS PaineWebber Inc. or its nominee,  will have all dividends and
other distributions on their shares of common stock automatically  reinvested in
additional  shares of common  stock,  unless such common  shareholders  elect to
receive  cash.Common  shareholders who elect to hold their shares in the name of
another  broker or nominee  should  contact  such broker or nominee to determine
whether,  or  how,  they  may  participate  in  the  Plan.The  ability  of  such
shareholders  to  participate  in the  Plan  may  change  if  their  shares  are
transferred into the name of another broker or nominee.

A common  shareholder  may elect not to participate in the Plan or may terminate
participation in the Plan at any time without penalty,  and common  shareholders
who have previously  terminated  participation  in the Plan may rejoin it at any
time.  Changes in elections must be made in writing to the Fund's transfer agent
and should  include  the  shareholder's  name and address as they appear on that
share  certificate or in the transfer agent's records.  An election to terminate
participation  in the Plan,  until such  election is changed,  will be deemed an
election by a common  shareholder to take all subsequent  distributions in cash.
An election  will be  effective  only for  distributions  declared  and having a
record date at least ten days after the date on which the election is received.

GENERAL INFORMATION (UNAUDITED) (CONCLUDED)

DIVIDEND REINVESTMENT PLAN (CONCLUDED)

Additional  shares of common stock  acquired under the Plan will be purchased in
the open market, on the NYSE or otherwise, at prices that may be higher or lower
than  the net  asset  value  per  share of the  common  stock at the time of the
purchase. The number of shares of common stock purchased with each dividend will
be equal to the result  obtained by dividing the amount of the dividend  payable
to a particular shareholder by the average price per share (including applicable
brokerage  commissions)  that the transfer  agent was able to obtain in the open
market.

The Fund will not issue any new shares of common  stock in  connection  with the
Plan. There currently is no charge to participants for reinvesting  dividends or
other distributions.  The transfer agent's fees for handling the reinvestment of
distributions  will be paid by the Fund.  However,  each  participant pays a pro
rata share of  brokerage  commissions  incurred  with  respect  to the  transfer
agent's  open  market   purchases  of  common  stock  in  connection   with  the
reinvestment of distributions. The automatic reinvestment of dividends and other
distributions  in shares of common  stock does not relieve  participants  of any
income tax that may be payable on such distributions.

Experience under the Plan may indicate that changes are desirable.  Accordingly,
the Fund  reserves the right to amend or terminate  the Plan with respect to any
dividend  or  other  distribution  if  notice  of the  change  is  sent  to Plan
participants at least 30 days before the record date for such distribution.  The
Plan also may be  amended or  terminated  by the  transfer  agent by at least 30
days' written notice to all Plan participants.  Additional information regarding
the Plan may be obtained from, and all correspondence concerning the Plan should
be directed to, the  transfer  agent at PFPC Inc.,  P.O. Box 43027,  Providence,
Rhode Island  02940-3027.  For further  information  regarding the Plan, you may
also contact the transfer agent directly at 1-800-331-1710.
