Letter from the Chairman
INVESCO Global Health Sciences Fund
April 1998


Dear Shareholder:

     During  the last six  months, an environment  of low  inflation  and strong
economic growth has helped to provide strong returns from health care stocks. We
have seen large-cap pharmaceutical companies drive performance of INVESCO Global
Health  Sciences  Fund  ("GHS" or the  "Fund"),  and we  continue  to expect the
pharmaceutical  sector  will be the  largest  sector in the  portfolio  over the
near-term. While past performance is no guarantee of future results, for the six
months ended April 30, 1998,  the Fund  returned  17.3% based on net asset value
("NAV"), and 34.7% based on market value.
     Since you  received  your copy of the Fund's 1997  Report to  Shareholders,
there have been two  significant  events for the Fund.  First, on April 3, 1998,
the Securities  and Exchange  Commission  ("SEC")  granted the Fund an exemptive
order, which permits the Fund to make quarterly  distributions at a rate of 2.5%
of NAV - 10%  annually  - to Fund  shareholders.  Implementation  of this  fixed
distribution  policy was  contingent  upon the grant by the SEC of the exemptive
order.  This order permits the Fund to include  realized  capital gains, if any,
when making  quarterly  distributions.  The Board of Trustees  implemented  this
policy at the quarter end following the grant of the exemptive order,  which was
April 30, 1998.
     On  April  16,  1998,  the Fund  launched  a new  website.  The site can be
accessed by typing in the Internet address  ghs.invesco.com  or by selecting the
Fund's link at INVESCO Funds Group,  Inc.'s ("IFG")  homepage,  www.invesco.com.
The  site  communicates  to  shareholders  and  new  customers   important  Fund
information  such as  historical  performance,  current  NAV and  stock  prices,
distribution history, reports to shareholders and news features.
     The Board of  Trustees  and IFG  believe  that these two  events  will help
manage the Fund's  discount to net asset  value.  The Board  approved  the fixed
distribution  policy as a result of ongoing analysis to identify strategies that
may be effective in  maintaining  smaller  discounts.  Similarly,  launching the
website was part of an enhanced investor relations program for the Fund designed
to  strengthen  the Fund's  presence in the financial  community.  We believe by
providing  the Fund  proactive  investor  relations  support  we are  helping to
enhance investors' understanding of the Fund, which could increase market demand
and reduce the discount.
     Your Board of Trustees  continues to evaluate  new ways to further  enhance
shareholder value. We are committed to serving our shareholders and look forward
to  assisting  you with  your  future  investment  needs.  Should  you ever need
assistance, please do not hesitate to contact us directly at 800-528-8765.

Sincerely,

Hubert L. Harris, Jr.

Report of Investment Manager
Invesco Global Health Sciences Fund
April 30, 1998
- --------------------------------------------------------------------------------
In the last six  months,  the  market  environment  for health  care  stocks has
significantly improved.  Continued low inflation and strong economic growth have
provided a positive  backdrop for equities  overall,  including  the health care
sector.  During this time period,  investors have placed  increased  emphasis on
earnings and liquidity,  creating a two-tier  health care equity market in which
market-leading pharmaceuticals outperformed smaller health care companies. Large
pharmaceutical  companies  remain a vital part of our  portfolio  strategy,  and
companies like  Bristol-Myers  Squibb,  Lilly (Eli) & Co.,  Merck & Co.,  Pfizer
Inc.,  SmithKline Beecham PLC, and Warner-Lambert Co. produced significant gains
for the  Fund in the  last  six  months.  We  continue  to  believe  that  large
pharmaceuticals  offer some of the best investment  opportunities  in the market
because these companies are benefiting from an improved regulatory  environment,
strong new product pipelines, and effective marketing campaigns.
     Another  area  providing  strong  returns  for the Fund during the last six
months was the medical devices and supplies subsector - especially Guidant Corp.
and  Medtronic  Inc.  These firms are  experiencing  accelerating  revenues  and
earnings, as patients seek to improve their quality of life as they age.
     While the Fund's private  placements  somewhat lagged the market during the
last six months, we remain confident that above average gains may be produced by
restricted  securities  over time.  Private  placements  will  remain a critical
ingredient  in the  portfolio's  composition  as the Fund's  closed-end  capital
structure allows us to take advantage of these investment opportunities.

Fund Performance
For the  six-month  period ended April 30, 1998,  the Fund had a total return of
17.26%  based on net asset  value and a total  return of 34.72%  based on market
value.  During  this  period,  both  the  net  asset  value  and  market  return
significantly  outperformed  the average  open-end  fund return of 12.70% in the
Lipper Health/Biotechnology category.
     For the  three-year  period ended April 30,  1998,  the Fund had an average
annual  return of 28.92%  based on net asset  value,  and 38.36% based on market
price performance.  Both of these returns also outperformed the average open-end
fund return of 26.11% for the Lipper Health/Biotechnology  category. (Of course,
past performance is not a guarantee of future results.)

Pharmaceuticals
We continue to believe that size  matters in the  pharmaceutical  industry,  and
large-cap  pharmaceutical  companies remain the dominant theme in the portfolio.
To be successful in the global economy, pharmaceutical companies must be able to
register,  market,  and  distribute  their  products  worldwide.  This  requires
substantial  capital and resources which are only available to large-cap  firms.
In  addition,  these  institutions  have the  financial  capability  to allocate
enormous  amounts of capital  towards  research  and  development,  resulting in
strong new product  pipelines.  This has  dramatically  improved  the  earnings'
outlook for these  companies,  as new drugs typically drive revenue and earnings
growth for pharmaceuticals.  Further, the Food and Drug Administration (FDA) has
significantly  cut the approval time for new drugs,  directly  benefiting  those
firms.
     Another  positive for the  pharmaceutical  industry is that  consumers  are
becoming  better educated and more aware of available  products.  In many cases,
patients are requesting prescriptions for their ailments before the doctor has a
chance to  recommend a product -  benefiting  pharmaceuticals  with large direct
marketing budgets.


<PAGE>
     Presently,  the Fund has focused over 50% of its assets in pharmaceuticals.
We remain  concentrated in  market-leading  names like Merck & Co., Pfizer Inc.,
and  Warner-Lambert  Co. In fact, our favorite  pharmaceutical  company  remains
Pfizer - one of the Fund's largest  holdings as of April 30, 1998.  Pfizer's new
anti-impotence  pill, called Viagra,  is easy to use with few side effects,  and
works  approximately  70% of the time. The potential for this drug is staggering
as it estimated that half of men between the ages of 40 and 70 have  experienced
some form of sexual  dysfunction.  At $7 to $10 per pill, it could easily be one
of the best-selling drugs of all time, perhaps producing average annual sales in
excess of $2 billion within a few years.  In addition,  Pfizer has begun testing
the drug on women which, if successful, could only enhance its market potential.

          Global Health  Sciences  Fund's Net Asset Value and Stock Price to the

          investment in the fund in January 1992.

     Although  large-cap  pharmaceutical  stocks  have  experienced  significant
appreciation  in the last six  months,  the Fund will  continue  to favor  these
issues. A fundamental  change has occurred in this subsector,  giving large- cap
pharmaceutical companies a distinct advantage over smaller drug companies. Until
this environment changes, we plan to remain heavily invested in this area.

Medical  Devices and Supplies
This area also  continues to produce strong returns for the Fund. As health care
systems throughout the world focus on reducing medical expenditures, exceptional
opportunities  exist for companies providing products which enhance patient care
while reducing  long-term costs. Some of the most significant gains in extending
the  quality  of life for  patients  have  been  made in the  field  of  cardiac
research.  Market-leading  companies  like Guidant Corp. and Medtronic Inc. have
experienced  tremendous growth in earnings, as their products for use in cardiac
rhythm management,  angioplasty devices,  coronary artery disease  intervention,
and cardiac  surgery have been  well-received  by the market.  We continue to be
positive on the medical  devices and supplies  subsector,  as current  valuation
levels  look  reasonable  compared  to the growth in  earnings.  However,  stock
selectivity  will remain crucial,  and the Fund will concentrate its investments
in companies with proprietary products and defensible market positions.

Biotechnology
Although  we  remain   optimistic   about  the   long-term   prospects  for  the
biotechnology   sector,   the  current  market  environment  favors  firms  with
predictable   earnings.   This  market  bias  has   negatively   affected   many
biotechnology  firms in the early  stages of product  development  and,  in many
cases, years away from being profitable.  We have focused the Fund's investments
in this sector towards companies with  commercially  viable products that are in
the latter stages of  development - a strategy we will maintain until the market
environment changes for this sector.

Health Care Delivery
The Fund has avoided health maintenance  organizations (HMOs) and hospitals over
the last six  months.  The  inability  of HMOs to  control  costs  has  produced
negative  sentiment  towards this  industry.  Although we are excited  about the
long-term  prospects of HMOs, we will avoid this  particular  industry until the
underlying  fundamentals  improve.  Instead, we have focused investments in this
subsector towards firms benefiting from the increased need for health care data,
like Cognizant Corp.  Cognizant offers proprietary research data to health care,
media, and technology companies.  This includes tracking  pharmaceutical data on
drug  use and  end-unit  sales,  which  is  highly  beneficial  to the  sector's
profitability.  The company is planning to split into two  companies in the near
future, IMS HEALTH and Nielsen Media Research,  with IMS HEALTH concentrating on
health care-related data.

Private Placements
When investing in private placements or restricted securities, the Fund attempts
to identify  promising young  companies with the potential to make  significant,
commercially  viable  contributions to the health care system. Due to the Fund's
unique  closed-end  capital  structure,  we are able to  invest up to 25% of the
Fund's assets in these types of securities.  This benefits  shareholders as Fund
management is able to examine  technology on the cutting edge of the health care
industry  before  the broad  market  has a chance to value  it,  and also  helps
management identify future trends within the industry. While past performance is
no guarantee of future results, over the three-year period ended April 30, 1998,
the Fund's restricted  securities produced an average annualized return of 
30.40% (on a gross return basis).

Chart:    This chart shows Fund's sector breakdown as of 4/30/98:
          pharmaceuticals - 57%, medical devices and supplies - 24%,
          health care delivery - 10%, biotechnology - 8%, and other - 1%.
*Holdings and composition of holdings are subject to change.

There  are  three  main  reasons  for the  reduction  in the  Fund's  restricted
securities  position over the last six months:  
o The phenomenal  bull market of the last six months significantly increased the
  value of the Fund's freely tradable assets, decreasing the percentage of total
  assets in restricted securities.
o Companies like Advanced Health and Cambridge Heart,  once private  placements,
  became freely  tradable over the last six months and are no longer  classified
  as restricted securities.
o A few  long-term  holdings  were  marked  down to reflect a decrease  in their
  market  value.  Our goal is to have 15% to 20% of the  portfolio in restricted
  securities.  The increase will be gradual as each  investment  requires proper
  due diligence and financial analysis.

     Although  restricted  securities  offer the  opportunity  for above average
returns,  their risky nature  reinforces the need for in-depth  research on each
company.  Currently,  we  are  excited  about  the  long-term  potential  of two
particular private placements:  Instrumentation  Metrics and Orchid Biocomputer.
Instrumentation   Metrics  has  developed  a  noninvasive   and   nondestructive
technology  platform that uses near-infrared  light in combination with advanced
algorithms to measure  blood  composition.  This  technology  may  revolutionize
clinical and analytical chemistry. Through the use of an optical processing unit
and  application-specific  software,  this platform technology can measure blood
analytes  without breaking the surface of the skin.  Currently,  the company has
targeted the  self-monitoring  of blood glucose by diabetics as the first market
in which to deploy its technology  platform.  This may allow diabetics,  of whom
there are more than 2.4  million  in the  United  States  alone,  to test  their
glucose  levels  multiple  times  a  day  without  the  discomfort  of  pricking
themselves  with a needle.  In addition,  the company feels that its proprietary
technology platform can be applied to various industries.
     Orchid  is  addressing  one  of  the  most  important  parameters  of  drug
discovery,  namely  increasing  sample  throughput  and  decreasing  the time of
experiments. By using the same technology used to make computer chips, Orchid is
creating  miniaturized  versions of drug  discovery and  diagnostic  instruments
found in laboratories around the world. These microchemical processors precisely
manipulate  complex mixtures of fluids and  simultaneously  perform thousands of
chemical  reactions.  These  processors  could  transform  the drug  development
process.  The  company  already has a strategic  collaboration  with  SmithKline
Beecham PLC and an affiliation with Sarnoff Corp., as well as working agreements
with the Department of Defense and Motorola Inc.
     Our goal when  investing  in private  companies is that one day these firms
will become freely tradable,  producing  significant capital gains for the Fund.
When these  institutions  complete  their initial  public  offering or otherwise
provide liquidity for their  shareholders,  it may unlock rewards for the Fund's
shareholders.  One such company that enhanced  shareholder returns over the last
six months was Nanogen,  Inc. Nanogen,  Inc. is attempting to integrate advanced
microelectronics  and molecular  biology into a platform  technology  with broad
commercial  applications  in  the  fields  of  medical  diagnostics,  biomedical
research,  genomics,  genetic testing and drug discovery.  If Nanogen's platform
technology  proves  to be  successful,  it  could  provide  a  low-cost,  highly
efficient,  accurate and versatile  integrated  system that could  significantly
improve the quality of health care.
     Nanogen,  Inc.  originally  purchased  by the  Fund as a  private  company,
completed  its IPO on April 13, 1998,  at a price $11 per share -  substantially
above our historical cost of $6 per share. Even though the company is public, we
are still required to carry the stock as a restricted  security throughout 1998.
During  this time  period,  we will  apply a  discount  to  market  value of 20%
starting from  Nanogen's IPO date,  and gradually  reduce the discount until the
security becomes freely tradable at the end of the year. In comparison,  private
companies generally are carried on the books at historical cost,  reflecting our
conservative bias when valuing private placements.
     Investors need to remember that, as exciting as these  technologies  sound,
these  companies  are in the early stages of  development  and it may be several
years before they are  profitable.  Looking  forward,  we will continue with our
disciplined,  long-term  approach to private  placement  investments,  gradually
increasing the Fund's  percentage of restricted  securities as sound  investment
opportunities present themselves. 
<PAGE>

Looking Forward
The health care sector should be a major engine of growth for world economies in
years to come.  We expect to  continue  to focus a  substantial  portion  of the
Fund's  assets on  market-leading  pharmaceutical  companies.  We believe  these
companies are  well-positioned  to benefit from dominant  market  positions,  an
improved  regulatory  environment and strong new product  pipelines.  The Fund's
exposure  to smaller  companies  will be  increased  through  our use of private
placements;   however,  that  increase  will  be  gradual,  because  we  have  a
comparatively narrow IPO calendar for the remainder of 1998. As long as interest
rates remain relatively stable, the technical  underpinnings for the health care
sector should remain positive.

Notes to Financial Statements
Invesco Global Health Sciences Fund
Unaudited
- --------------------------------------------------------------------------------

NOTE 1 - Organization And Significant Accounting Policies. Invesco Global Health
Sciences Fund (the "Fund") was organized as a  Massachusetts  Business  Trust on
November 18, 1991 and commenced  investment  operations on January 24, 1992. The
investment  objective  of the  Fund  is to  seek  capital  appreciation  through
investments  in the  health  sciences  related  business  sectors.  The  Fund is
registered  under  the  Investment   Company  Act  of  1940  (the  "Act")  as  a
diversified, closed-end management investment company.
     The following is a summary of significant  accounting policies consistently
followed  by the  Fund  in the  preparation  of its  financial  statements.  The
preparation  of financial  statements  in  conformity  with  generally  accepted
accounting principles requires management to make estimates and assumptions that
affect  the  reported  amounts  of assets  and  liabilities  and  disclosure  of
contingent  assets and  liabilities at the date of the financial  statements and
the reported amounts of income and expenses during the reporting period.  Actual
results could differ from those estimates.

A.  Security  Valuation  -  Equity  securities  traded  on  national  securities
exchanges or in the  over-the-counter  market are valued at the last sales price
in the market where such securities are primarily  traded.  If last sales prices
are not  available,  securities  are  valued at the  highest  closing  bid price
obtained  from one or more dealers  making a market for such  securities or by a
pricing service approved by the Fund's board of trustees.
     Debt  securities  are valued at  evaluated  bid prices as  determined  by a
pricing  service  approved by the Fund's  board of trustees.  If  evaluated  bid
prices are not available, debt securities are valued by averaging the bid prices
obtained from one or more dealers making a market for such securities.
     Foreign  securities are valued at the closing price on the principal  stock
exchange  on which they are  traded.  In the event that  closing  prices are not
available  for foreign  securities,  prices will be obtained  from the principal
stock exchange at or prior to the close of the New York Stock Exchange.  Foreign
currency  exchange rates are determined daily prior to the close of the New York
Stock Exchange.
     If  market  quotations  or  pricing  service  valuations  are  not  readily
available, securities are valued at fair value as determined in good faith under
procedures  established by the Fund's board of trustees.  Restricted  securities
are valued in  accordance  with  procedures  established  by the Fund's board of
trustees.
     Short-term  securities  are stated at  amortized  cost (which  approximates
market value) if maturity is 60 days or less at the time of purchase,  or market
value if maturity is greater than 60 days.
     Assets and liabilities  initially  expressed in terms of foreign currencies
are translated into U.S. dollars at the prevailing market rates as quoted by one
or more banks or dealers on the date of  valuation.  The cost of  securities  is
translated  into U.S.  dollars  at the rates of  exchange  prevailing  when such
securities are acquired. Income and expenses are translated into U.S. dollars at
rates of exchange prevailing when accrued.

B.  Repurchase  Agreements  - Repurchase  agreements  held by the Fund are fully
collateralized  by U.S.  government  securities  and such  collateral  is in the
possession of the Fund's custodian.  The collateral is evaluated daily to ensure
its market value exceeds the current market value of the  repurchase  agreements
including  accrued  interest.  In the  event of  default  on the  obligation  to
repurchase,  the Fund has the right to liquidate  the  collateral  and apply the
proceeds  in  satisfaction  of  the  obligation.  In the  event  of  default  or
bankruptcy by the other party to the agreement,  realization and/or retention of
the collateral or proceeds may be subject to legal proceedings.
<PAGE>

C. Security  Transactions And Related Investment Income - Security  transactions
are  accounted  for on the trade date and  dividend  income is  recorded  on the
exdividend date.  Certain dividends from foreign  securities will be recorded as
soon as the Fund is informed of the  dividend  if such  information  is obtained
subsequent to the ex-dividend date.  Interest income,  which may be comprised of
stated  coupon rate,  market  discount,  original  issue  discount and amortized
premium,  is recorded  on the  accrual  basis.  Discounts  and  premiums on debt
securities  purchased are amortized over the life of the respective  security as
adjustments   to  interest   income.   Cost  is   determined   on  the  specific
identification basis.
     The Fund may have  elements  of risk  due to  concentrated  investments  in
specific  industries  or foreign  issuers  located in a specific  country.  Such
concentrations  may subject the Fund to additional  risks  resulting from future
political or economic conditions and/or possible  impositions of adverse foreign
governmental laws or currency exchange restrictions. Net realized and unrealized
gain or loss from  investment  securities  includes  fluctuations  from currency
exchange rates and  fluctuations  in market value.  The Fund's use of short-term
forward foreign  currency  contracts may subject it to certain risks as a result
of  unanticipated  movements in foreign  exchange rates.  The Fund does not hold
short-term forward foreign currency contracts for trading purposes. The Fund may
hold foreign currency in anticipation of settling foreign security  transactions
and not for investment purposes.
      The net position of such forward  contracts is presented in the  Statement
of Assets and Liabilities and may have additional elements of risk which may not
necessarily be reflected.
     Restricted  securities  held by the Fund may not be sold  except  in exempt
transactions  or in a public  offering  registered  under the  Securities Act of
1933.  The risk of investing in such  securities  is generally  greater than the
risk of investing in the securities of widely held,  publicly traded  companies.
Lack of a secondary  market and resale  restrictions may result in the inability
of the Fund to sell a security at a fair price and may  substantially  delay the
sale of the security which the Fund seeks to sell. In addition, these securities
may exhibit greater price volatility than securities for which secondary markets
exist. The Fund has demand registration rights for certain restricted securities
held at April  30,  1998,  which can be  exercised  upon the  registration  of a
qualifying  public  offering by each  company in the future.  The Fund may incur
registration costs associated with these public offerings. There is no assurance
such offerings will occur.

D.  Federal And State Taxes - The Fund has  complied,  and  continues to comply,
with the  provisions  of the  Internal  Revenue  Code  applicable  to  regulated
investment  companies and,  accordingly,  has made or intends to make sufficient
distributions  of net investment  income and net realized capital gains, if any,
to relieve it from all federal and state income taxes and federal excise taxes.
     To the extent future  capital gains are offset by capital loss  carryovers,
such gains will not be distributed to shareholders.
     Dividends paid by the Fund from net investment  income and distributions of
net realized  short-term  capital  gains are, for federal  income tax  purposes,
taxable as ordinary income to shareholders.
     Investment  income  received from foreign sources may be subject to foreign
witholding  taxes.  Dividend  and  interest  income  is shown  gross of  foreign
witholding taxes in the accompanying financial statements.


<PAGE>
E. Dividends And  Distributions To Shareholders - Dividends and distributions to
shareholders are recorded by the Fund on the  exdividend/distribution  date. The
Fund  distributes  net realized  capital gains,  if any, to its  shareholders at
least annually,  if not offset by capital loss carryovers.  Income distributions
and capital gain  distributions  are  determined in  accordance  with income tax
regulations  which may differ from  generally  accepted  accounting  principles.
These  differences  are  primarily  due  to  differing   treatments  for  market
discounts,   amortized  premiums,  foreign  currency  transactions,   nontaxable
dividends,  net  operating  losses and expired  capital loss  carryforwards.  

F. Forward Foreign Currency  Contracts - The Fund enters into short-term forward
foreign  currency  contracts in  connection  with planned  purchases or sales of
securities as a hedge against fluctuations in foreign exchange rates pending the
settlement of transactions  in foreign  securities.  A forward foreign  currency
contract is an agreement  between  contracting  parties to exchange an amount of
currency  at some  future  time at an agreed  upon  rate.  These  contracts  are
marked-to-market  daily and the  related  appreciation  or  depreciation  of the
contracts is presented in the Statement of Assets and Liabilities.  
     At April  30,  1998,  the Fund had  outstanding  forward  foreign  currency
contracts.  Unrealized  gain or loss on forward  foreign  currency  contracts is
calculated  daily as the difference  between the contract  exchange rate and the
closing forward rate applied to the face amount of the contract. 
     Forward   foreign   currency   contracts   held  by  the  Fund  are   fully
collateralized  by other  securities  which  are  notated  in the  Statement  of
Investment  Securities  and such  collateral is in the  possession of the Fund's
custodian.  The collateral is evaluated daily to ensure its market value exceeds
the current market value of the forward foreign currency contract.

G.  Expenses - Under an  agreement  between  the Fund and the Fund's  custodian,
agreed upon  Custodian  Fees and Expenses are reduced by credits  granted by the
custodian from any temporarily univested cash. Such credits are included in Fees
and Expenses Paid Indirectly in the Statement of Operations.

NOTE 2 - Investment Advisory And Other Agreements.
INVESCO  Trust  Company  ("ITC")  serves as the Fund's  investment  adviser.  As
compensation  for its services to the Fund, ITC receives an investment  advisory
fee which is accrued daily at the applicable  rate and paid monthly.  The fee is
based on the annual rate of 1.00% on the first $500 million of ending weekly net
assets  and  0.90% on ending  weekly  net  assets  in  excess  of $500  million.
Effective  February 4, 1998, such  responsibilities  were transferred to INVESCO
Funds Group, Inc. ("IFG"). 
     In accordance with an Administrative Agreement, the Fund pays IFG an annual
fee of $250,000 to provide administrative, accounting and clerical services. The
fee is accrued daily and paid monthly.

NOTE 3 - Purchases And Sales Of Investment Securities.  
For the six months ended April 30, 1998,  the  aggregate  cost of purchases  and
proceeds  from sales of investment  securities  (excluding  all U.S.  government
securities  and  short-term  securities)  were  $281,831,987  and  $279,884,133,
respectively. 
     There were no purchases or sales of U.S. Government securities.

NOTE  4  -  Appreciation  And  Depreciation.   
At April 30, 1998,  the gross  appreciation  of securities in which there was an
excess  of  value  over  tax  cost  amounted  to  $167,573,116   and  the  gross
depreciation  of  securities in which there was an excess of tax cost over value
amounted to $16,278,064, resulting in net appreciation of $151,295,052. 

NOTE 5 - Transactions  With  Affiliates And Affiliated  Companies.  
Certain of the Fund's  officers and trustees are also  officers and directors of
ITC or IFG. 
     An affiliated  company  represents  ownership by the Fund of at least 5% of
the voting  securities of the issuer during the period, as defined in the Act. A
summary of the transactions during the six months ended April 30, 1998, in which
the issuer was an affiliate of the Fund, is as follows on the next page:

* It is  estimated  that the source of the  distribution  is  long-term  capital
  gains.  However, it is possible that the source of a portion of the 
  distribution may be later  recharacterized.  

Dividend Reinvestment Plan 
Shareholders of the Fund who have Shares registered  directly in their own names
automatically participate in the Fund's Dividend Reinvestment Plan (the "Plan"),
unless  and  until an  election  is made to  withdraw  from  the Plan as  herein
provided. State Street Bank and Trust Company (the "Agent"), acts as agent under
the Plan on behalf of participating  shareholders.  Shareholders who do not wish
to have  distributions  automatically  reinvested  should so notify the Fund c/o
State Street Bank and Trust Company, P.O. Box 366, Boston,  Massachusetts 02101.
Under  the  Plan,  all  of  the  Fund's  dividends,   capital  gains  and  other
distributions to shareholders  will be reinvested in full and fractional  Shares
as described below. A shareholder who owns Shares  registered in his broker's or
nominee  name,  and whose  broker  does not  provide  facilities  for a dividend
reinvestment  program,  may be required to have his Shares registered in his own
name in order to participate in the Plan. Shareholders wishing to participate in
the Plan whose Shares are held in the name of a broker or nominee should consult
their brokers as to how to accomplish dividend reinvestment.
     Whenever  the Fund  declares an income  dividend,  a capital  gain or other
distribution  (collectively,  "Dividends") in cash, non-participants in the Plan
will receive cash and  participants  in the Plan will receive the  equivalent in
Shares.  Whenever  the  Fund  declares  Dividends  in  additional  unissued  but
authorized  shares ("Newly  Issued  Shares")  non-participants  in the Plan will
receive Newly Issued Shares and participants in the Plan will receive shares. In
either instance,  the shares received by Plan  participants  will be acquired by
the  Agent  for the  participant's  account,  depending  upon the  circumstances
described  below,  either (i) through  receipt of Newly Issued Shares or (ii) by
the purchase of outstanding Shares on the open market ("Open-Market  Purchases")
on the New York Stock Exchange or elsewhere.
     If on the  payment  date for a  Dividend  the net asset  value per Share is
equal to or less  than the  market  price  per Share  plus  estimated  brokerage
commissions (such condition being referred to herein as "Market  Premium"),  the
Agent  will  purchase  from  the Fund  Newly  Issued  Shares  on  behalf  of the
participant at a price per Share equal to the greater of the net asset value per
Share or 95% of the then current market price per Share.  This discount from the
current market price reflects  savings in underwriting and other costs which the
Fund would otherwise incur to raise additional capital.
     If on the  payment  date for a  Dividend  the net asset  value per Share is
greater than the market price per Share (such condition being referred to herein
as "Market Discount"),  the Agent will endeavor to invest the Dividend amount in
Shares  acquired on behalf of the participant in Open Market  Purchases.  In the
event of a Market  Discount  on the payment  date,  the Agent will have up to 30
days after the payment date to invest the Dividend  amount in Shares acquired in
Open-Market Purchases.
<PAGE>

     Registered   shareholders   who  acquire   their   Shares  in   open-market
transactions  and  who  do  not  wish  to  have  their  Dividends  automatically
reinvested  should so  notify  the Fund in  writing.  If a  shareholder  has not
previously  elected to receive  cash  Dividends  and the Agent does not  receive
notice of an election to receive cash Dividends  prior to the record date of any
Dividends,   the  Shareholder  will  automatically  receive  such  Dividends  in
additional Shares.
     Participants  in the Plan may withdraw  from the Plan by providing  written
notice to the Agent at least 30 days prior to the  applicable  Dividend  payment
date.  When a participant  withdraws  from the Plan, or upon  termination of the
Plan as provided  below,  certificates  for whole Shares credited to his account
under the Plan  will,  upon  request,  be issued.  Whether or not a  participant
requests that  certificates  for whole Shares be issued,  a cash payment will be
made for any fraction of a Share  credited to such account.  
     When the  Securities  and Exchange  Commission  (SEC)  granted the Fund the
necessary  exemptive relief, the Plan was amended so that Open-Market  Purchases
will be made only in the event  that the Fund  declares  an income  dividend,  a
capital gain or other distribution payable only in cash.
     The Agent will  maintain all  shareholder  accounts in the Plan and furnish
written confirmations of all transactions in the accounts, including information
needed by  shareholders  for personal and tax records.  Shares in the account of
each Plan participant will be held by the Agent in non-certificated  form in the
name of the participant,  and each shareholder's proxy will include those shares
purchased pursuant to the Plan. Each participant, nevertheless, has the right to
receive certificates for whole Shares owned. The Agent will distribute all proxy
solicitation materials to participating shareholders.
     In the case of shareholders, such as banks, brokers or nominees, which hold
Shares for others who are the beneficial  owners  participating in the Plan, the
Agent will  administer  the Plan on the basis of the number of Shares  certified
from time to time by the shareholder as representing  the total amount of Shares
registered  in the  shareholder's  name and held for the  account of  beneficial
owners participating in the Plan.
     There will be no charge to  participants  for  reinvesting  Dividends other
than their share of brokerage  commissions as discussed  below. The Agent's fees
for  administering  the Plan and handling the  reinvestment of Dividends will be
paid by the Fund. Each participant's account will be charged a pro-rata share of
brokerage commissions incurred with respect to the Agent's Open-Market Purchases
in  connection  with  the  reinvestment  of  Dividends.  Brokerage  charges  for
purchasing small amounts of Shares for individual  accounts through the Plan are
expected  to be less  than the usual  brokerage  charges  for such  transactions
because the Agent will be purchasing  Shares for all the  participants in blocks
and  prorating  the  lower  commission  that may be  attainable.  
     The automatic  reinvestment  of Dividends will not relieve  participants of
any income tax which may be payable on such  Dividends.  In the case of non U.S.
participants whose Dividends are subject to United States income tax withholding
and in the case of any participants  subject to 30% federal backup  withholding,
the Agent will reinvest  Dividends  after deduction of the amount required to be
withheld.
     The Fund  reserves  the  right to amend or  terminate  the Plan by  written
notice  to  participants.  All  correspondence  concerning  the Plan  should  be
directed to the Agent at the address  referred to in the first paragraph of this
section.
