accounts of  Participating  Insurance  Companies.  The Funds have the  following
investment objectives:

Industrial Income Fund: to seek the best possible current income while following
sound   investment   practices.   Capital  growth  potential  is  an  additional
consideration  in the  selection  of  portfolio  securities.  The Fund  normally
invests at least 65% of its total assets in dividend-paying common stocks. Up to
10% of the Fund's total assets may be invested in equity  securities that do not
pay   regular   dividends.   The   remaining   assets  are   invested  in  other
income-producing  securities,  such as  corporate  bonds.  The Fund also has the
flexibility to invest in other types of securities.

Health  Sciences Fund: to seek capital  appreciation.  The Health  Sciences Fund
normally  invests  at least 80% of its total  assets  in  equity  securities  of
companies that develop,  produce,  or distribute products or services related to
health care.

Technology  Fund: to seek capital  appreciation.  The  Technology  Fund normally
invests at least 80% of its total  assets in equity  securities  of companies in
technology-related   industries  such  as  computers,   communications,   video,
electronics, oceanography, office and factory automation, and robotics.

SUMMARY

      The Company is a registered,  open-end management  investment company that
was  organized as a Maryland  corporation  on August 19, 1993,  and is currently
comprised of nine diversified investment portfolios.  This Prospectus relates to
shares  of  three  of  the  portfolios:  the  INVESCO  VIF -  Industrial  Income
Portfolio,  the  INVESCO  VIF - Health  Sciences  Portfolio  and the INVESCO VIF
Technology Portfolio (collectively,  the "Funds").  Additional portfolios may be
created  from  time  to  time.  The  overall  supervision  of  each  Fund is the
responsibility of the Company's board of directors.

      The  Company is  intended to be a funding  vehicle  for  variable  annuity
contracts  and  variable  life  insurance  contracts  to be offered by  separate
accounts  of  certain  life  insurance   companies   ("Participating   Insurance
Companies").  Fund shares are not available for purchase  other than through the
purchase of such  contracts.  The variable  annuity and variable life  insurance
contracts are described in separate prospectuses of the Participating  Insurance
Companies  (the  "Separate  Account  Prospectuses").   The  Company  assumes  no
responsibility  for the Separate Account  Prospectuses.  A contract owner should
refer to the Separate Account Prospectuses for information on how to purchase or
surrender a contract,  make partial  withdrawals  of contract  values,  allocate
contract  values to one or more of the  Funds,  or change  existing  allocations
among investment alternatives, including the Funds.

<PAGE>

      Each Fund has its own distinct investment objective.  There is, of course,
no guarantee that any Fund will achieve its investment objective. The Industrial
Income Fund seeks to attain its  investment  objective by investing at least 65%
of its total  assets in  dividend-paying  common  stocks,  with up to 10% of its
total assets invested in equity securities that do not pay regular dividends and
the remainder invested in other income-producing  securities,  such as corporate
bonds.  The Health  Sciences  Fund seeks to attain its  investment  objective by
investing  at least 80% of its total  assets in equity  securities  of companies
which develop,  produce,  or distribute  products or services  related to health
care. The Technology Fund seeks to attain its investment  objective by investing
at  least  80%  of its  total  assets  in  equity  securities  of  companies  in
technology-related   industries  such  as  computers,   communications,   video,
electronics,  oceanography,  office and  factory  automation,  and  robotics.  A
discussion of each Fund's  investment  objective and policies is provided  below
under the caption "Investment Objectives and Policies."

     Various  types of risks are  involved  with each  Fund.  Each Fund may lend
portfolio  securities and may enter into  repurchase  agreements with respect to
debt  instruments  eligible for investment by that Fund. Each Fund may invest up
to 15% of its net assets in illiquid securities. Each Fund also may invest up to
25% of its total assets  directly in foreign  securities,  which present certain
additional  risks not  associated  with  investments  in domestic  companies and
markets.  Securities of Canadian  issuers and  securities  purchased by means of
American  Depository  Receipts  ("ADRs") are not subject to this 25% limitation.
The  Industrial  Income  Fund  may  invest  up to  15% of its  total  assets  in
lower-rated  debt  securities  that  present a greater  risk of default and have
prices that fluctuate more than those of higher-rated securities. The Technology
and Health  Sciences  Funds  will each be  concentrated  in a specific  business
sector.  Compared to the broad market, an individual sector may be more strongly
affected by changes in the economic  climate,  broad market  shifts,  moves in a
particular dominant stock, or regulatory  changes.  Each of the Funds may invest
in options and futures  contracts,  each of which presents special risks.  These
and other risks are discussed below under the caption "Risk Factors."

     INVESCO Funds Group, Inc.  ("INVESCO"),  the Funds' investment adviser, is
primarily  responsible  for  providing  the Company with various  administrative
services  and  supervising  the  Company's  daily  business  affairs.  Portfolio
management is provided to each Fund by its sub-adviser (referred to collectively
with INVESCO as "Fund  Management").  INVESCO  Trust Company  ("INVESCO  Trust")
serves as sub-adviser  to the Funds.  Each Fund pays INVESCO an advisory fee for
the management of its  investments and business  affairs.  A discussion of these
fees and  additional  information  about  INVESCO and INVESCO Trust are provided
below under the caption "Management."

INVESTMENT OBJECTIVES AND POLICIES

      The investment  objective of each Fund, as described below, is fundamental
and may be changed only by vote of a majority of the outstanding  shares of that
Fund. There is no assurance that any Fund will achieve its investment objective.
Any  investment  policy  of a Fund  may be  changed  by the  Company's  board of
directors without shareholder  approval unless the policy is one required by the
Fund's  fundamental  investment  restrictions  set  forth  in the  Statement  of
Additional  Information.  When  Fund  Management  believes  market  or  economic
conditions are unfavorable, each of the Funds may assume a defensive position by
temporarily  investing  up to 100% of its  total  assets in high  quality  money
market instruments,  such as short-term U.S. government obligations,  commercial
paper or repurchase  agreements,  high quality  corporate  bonds or notes, or by
holding cash.

      Because  prices  of  stocks  fluctuate  from day to day,  the  value of an
investment  in any of the  Funds  will  vary  based  upon  the  specific  Fund's
investment  performance.  Many of the Funds invest in  different  companies in a
variety of  industries  in order to attempt to reduce its  overall  exposure  to
investment and market risks. There is no assurance that any Fund will attain its
objectives.

Industrial Income Fund

      The investment objective of the Industrial Income Fund is to seek the best
possible  current income while following  sound  investment  practices.  Capital
growth  potential is an additional  consideration  in the selection of portfolio
securities.

      The  Industrial  Income  Fund  normally  invests at least 65% of its total
assets in  dividend-paying  common stocks.  Up to 10% of the Fund's total assets
may be invested in equity  securities  that do not pay  regular  dividends.  The
remaining  assets are  invested in other  income-producing  securities,  such as
corporate bonds and other straight debt securities ("debt securities"). The Fund
also has the  flexibility to invest in preferred  stock and  convertible  bonds.
There is no maximum  limit on the amount of equity or debt  securities  in which
the Fund may invest.

      The Industrial Income Fund may invest no more than 15% of its total assets
in debt  securities  that are  rated  below  BBB by  Standard  & Poor's  Ratings
Services, a division of The McGraw-Hill  Companies,  Inc. ("Standard & Poor's"),
or Baa by Moody's Investors Service, Inc. ("Moody's"),  and in no event will the
Fund ever invest in a debt security  rated below CCC by Standard & Poor's or Caa
by Moody's.  Generally, bonds rated in one of the top four rating categories are
considered  "investment  grade."  However,  those in the fourth highest category
(Standard & Poor's BBB or Moody's Baa) may have speculative  characteristics and
a weaker  ability to pay  interest or repay  principal  under  adverse  economic



<PAGE>


conditions  or  changing  circumstances.  The  risks of  investing  in debt
securities  rated  lower than BBB by  Standard  & Poor's or Baa by  Moody's  are
discussed  below  under the caption  "Risk  Factors."  See the  Appendix to this
Prospectus for a specific description of each corporate bond rating category.

Health Sciences Fund

      The  investment  objective of the Health  Sciences Fund is to seek capital
appreciation.  The  investment  strategy  used  in  attempting  to  attain  this
investment  objective is aggressive;  holdings are focused on equity  securities
whose price  appreciation  is expected  to outpace  that of the health  sciences
business sector.  These stocks may not pay regular dividends.  The Fund normally
invests at least 80% of its total  assets in the equity  securities  (common and
preferred stocks, and convertible bonds) of companies which develop, produce, or
distribute products or services related to health care.

      The health sciences  business sector consists of numerous  industries.  In
deciding whether a company is principally  engaged in that business sector, Fund
Management  must determine  that the company  derives more than 50% of its gross
income or net sales from activities in that sector or that the company dedicates
more than 50% of its assets to the production of revenues from that sector.  If,
based on available  financial  information,  a question exists whether a company
meets one of these standards,  Fund Management  determines whether the company's
primary business is within the health sciences business sector.

      The remainder of the Health  Sciences Fund's assets may be invested in any
securities  or  other  instruments   deemed   appropriate  by  Fund  Management,
consistent  with  the  Fund's  investment   policies  and  restrictions.   These
investments  include debt securities issued by companies  principally engaged in
the  health  sciences  business  sector,  debt or  equity  securities  issued by
companies  outside that business sector,  short-term high grade debt obligations
maturing  no later  than one year  from  the date of  purchase  (including  U.S.
government  and  agency  securities,  domestic  bank  certificates  of  deposit,
commercial  paper  rated at least A-2 by  Standard  & Poor's  or P-2 by  Moody's
Investors Service, Inc., and repurchase agreements) and cash.

Technology Fund

      The investment objective  of  the  Technology  Fund  is to  seek  capital
appreciation.  The  investment  strategy  used  in  attempting  to  attain  this
investment  objective is aggressive.  Holdings are focused on equity  securities
whose price  appreciation is expected to outpace that of the overall  technology
business sector.  These stocks may not pay regular dividends.  The Fund normally
invests at least 80% of its total  assets in the equity  securities  (common and
preferred  stocks,  and  convertible  bonds) of companies in  technology-related
industries such as computers, communications, video, electronics,  oceanography,
office and factory automation, and robotics.


<PAGE>





      The  technology  business  sector  consists  of  numerous  industries.  In
deciding  whether a company is principally  engaged in the  technology  business
sector, Fund Management must determine that the company derives more than 50% of
its gross  income or net  sales  from  activities  in that  sector;  or that the
company dedicates more than 50% of its assets to the production of revenues from
that sector.  If, based on available  financial  information,  a question exists
whether  a company  meets one of these  standards,  Fund  Management  determines
whether the company's primary business is within that sector.

      The  remainder  of the  Technology  Fund's  assets may be  invested in any
securities  or  other  instruments   deemed   appropriate  by  Fund  Management,
consistent  with  the  Fund's  investment   policies  and  restrictions.   These
investments  include debt securities issued by companies  principally engaged in
the technology  business sector,  debt or equity  securities issued by companies
outside that business sector, short-term high grade debt obligations maturing no
later than one year from the date of purchase  (including  U.S.  government  and
agency securities, domestic bank certificates of deposit, commercial paper rated
at least A-2 by Standard & Poor's or P-2 by Moody's Investors Service, Inc., and
repurchase agreements), and cash.

RISK FACTORS

      Contract owners should  consider the special  factors  associated with the
policies  discussed  below in  determining  the  appropriateness  of  allocating
contract  values to one or more of the Funds.  See the  Statement of  Additional
Information for a discussion of additional risk factors.

Potential  Conflicts.  The  Company  has  received  an  exemptive  order  of the
Securities  and  Exchange  Commission  that  permits  the sale of Fund shares to
variable annuity separate accounts and variable life insurance separate accounts
of affiliated and unaffiliated  Participating  Insurance Companies.  The Company
currently does not foresee any  disadvantages  to the owners of variable annuity
or variable life insurance contracts arising from the fact that the interests of
those owners may differ.  Nevertheless,  the Company's  board of directors  will
monitor events in order to identify any material irreconcilable  conflicts which
may possibly arise due to  differences of tax treatment or other  considerations
and to determine what action, if any, should be taken in response thereto.

Credit and Market Risks.            All     securities,     including    those
purchased   by  each  Fund,   are  subject  to  some  degree  of  credit  risk
and  market  risk.  Credit  risk  refers  to  the  ability  of  an  issuer  of
a  debt   security   to  pay  its   principal   and   interest,   and  to  the
earnings   stability  and  overall   financial   soundness  of  an  issuer  of



<PAGE>

an equity  security.  Market risk refers to the  volatility of a security's
price in response to changes in conditions in securities markets in general and,
particularly  in the case of debt  securities,  changes in the overall  level of
interest  rates.  An increase  in interest  rates will tend to reduce the market
values of debt  securities,  whereas a decline  in  interest  rates will tend to
increase their values.

      To limit  exposure to credit risks,  each Fund, as a matter of fundamental
policy, will be diversified. With respect to 75% of each Fund's total assets, no
more than 5% of the  purchasing  Fund's  total  assets  will be  invested in the
securities of any one issuer.  In addition,  no more than 25% of the  Industrial
Income  Fund's  total  assets  will  be  invested  in any  one  industry.  These
percentage limitations apply immediately after a purchase or initial investment.
Any subsequent change in a percentage  resulting from fluctuations in value will
not require elimination of any security from a Fund. The credit risk exposure of
the Health  Sciences  and  Technology  Funds may be increased by their policy of
concentrating  investments in specific  business  sectors.  See "Risk Factors --
Concentration."

Portfolio  Lending.  Each Fund may make  loans of its  portfolio  securities  to
broker-dealers or other  institutional  investors under contracts requiring such
loans to be callable at any time and to be secured continuously by collateral in
cash,  cash  equivalents,  high  quality  short-term  government  securities  or
irrevocable  letters  of credit  maintained  on a current  basis at an amount at
least equal to the market value of the securities loaned.  This practice permits
a Fund to earn income,  which, in turn, can be invested in additional securities
to pursue the Fund's  investment  objective.  The lending Fund will  continue to
collect the  equivalent  of the interest or dividends  paid by the issuer on the
securities loaned and will also receive either interest  (through  investment of
cash  collateral)  or a fee (if the  collateral  is  government  securities).  A
lending Fund may pay finder's and other fees in connection  with its  securities
loans.

      Lending  securities  involves certain risks, the most significant of which
is the risk  that a  borrower  may fail to  return a  portfolio  security.  Fund
Management monitors the  creditworthiness of borrowers in order to minimize such
risks.  A Fund will not lend any  security  if, as a result  of that  loan,  the
aggregate  value of  securities  then on loan would exceed  331/3% of the Fund's
total assets (taken at market value).

Repurchase  Agreements.  Each Fund may enter  into  repurchase  agreements  with
respect  to  debt  instruments  eligible  for  investment  by that  Fund.  These
agreements  are entered  into with member banks of the Federal  Reserve  System,
registered  broker-dealers,  and registered  government securities dealers which
are deemed  creditworthy by Fund Management  (subject to review by the Company's
board of directors). A repurchase agreement is a means of investing monies for a
short period.  In a repurchase  agreement,  the Fund acquires a debt  instrument



<PAGE>


(generally a  security issued  by the  U.S. government or an agency thereof, a
banker's acceptance or a certificate of deposit) subject to resale to the seller
at an agreed upon price and date  (normally the next business day). If the other
party defaults on its obligation to repurchase the security,  a Fund could incur
costs or delays in seeking to sell the security.

      To minimize risks  associated with repurchase  agreements,  the securities
underlying  each  repurchase  agreement  will be  maintained  with the Company's
custodian  in an  amount  at  least  equal to the  repurchase  price  under  the
agreement  (including  accrued  interest),  and such agreements will be effected
only with parties that meet certain  creditworthiness  standards  established by
the Company's board of directors. No Fund will enter into a repurchase agreement
maturing in more than seven days if as a result more than 15% of that Fund's net
assets  would be  invested  in such  repurchase  agreements  and other  illiquid
securities.

Portfolio Turnover.  There are no fixed limitations regarding portfolio turnover
for any of the Funds.  Although the Funds do not trade for  short-term  profits,
securities  may be sold without regard to the time they have been held in a Fund
when,  in the opinion of Fund  Management,  market  considerations  warrant such
action.  Therefore, the portfolio turnover rates of the Funds may be higher than
those of other  investment  companies  with  comparable  investment  objectives.
Increased portfolio turnover would cause a Fund to incur greater brokerage costs
than would  otherwise be the case. The actual  portfolio  turnover rates for the
Industrial  Income Fund are set forth under "Financial  Highlights." Each of the
other Funds is actively traded and is expected to have a portfolio turnover rate
that could exceed 200%. The Company's brokerage allocation  policies,  including
the consideration of sales of Participating Life Insurance  Companies'  variable
annuity and variable life insurance  contracts when  selecting  among  qualified
brokers offering  comparable best price and execution on Fund transactions,  are
discussed in the Statement of Additional Information.

Illiquid  and Rule  144A  Securities.  The  Funds  are  authorized  to invest in
securities  that are illiquid  because they are subject to restrictions on their
resale  ("restricted  securities")  or because,  based upon their  nature or the
market for such securities,  they are not readily  marketable.  However,  a Fund
will not  purchase  any such  security if the  purchase  would cause the Fund to
invest  more  than 15% of its net  assets  in  illiquid  securities.  Repurchase
agreements  maturing  in more than seven days will be  considered  illiquid  for
purposes of this restriction. Investments in illiquid securities involve certain
risks to the extent  that a Fund may be unable to dispose of such a security  at
the time desired or at a  reasonable  price.  In addition,  in order to resell a
restricted  security, a Fund might have to bear the expense and incur the delays
associated with effecting registration.



<PAGE>




      Certain  restricted  securities  that are not  registered  for sale to the
general public,  but that can be resold to  institutional  investors ("Rule 144A
Securities"), may be purchased without regard to the foregoing 15% limitation if
a  liquid  institutional  trading  market  exists.  The  liquidity  of a  Fund's
investments   in  Rule  144A   Securities   could  be  impaired  if  dealers  or
institutional investors become uninterested in purchasing these securities.  The
Company's  board of directors has delegated to Fund  Management the authority to
determine the liquidity of Rule 144A Securities  pursuant to guidelines approved
by the board.  For more  information  concerning Rule 144A  Securities,  see the
Statement of Additional Information.

Foreign  Securities.  Each Fund may  invest up to 25% of its total  assets,
measured at the time of purchase, directly in foreign securities. Investments in
securities of foreign companies  (including Canadian  securities,  which are not
subject to the 25% limitation) and in foreign markets involve certain additional
risks not associated  with  investments in domestic  companies and markets.  For
U.S. investors, the returns on foreign securities are influenced not only by the
returns  on  the   foreign   investments   themselves,   but  also  by  currency
fluctuations.  That is, when the U.S.  dollar  generally  rises against  foreign
currencies,  returns on foreign securities for a U.S. investor may decrease.  By
contrast, in a period when the U.S. dollar generally declines, those returns may
increase.

      Other risks of international investing to consider include:

     -less publicly available information than is generally available about U.S.
issuers;

     -differences in accounting, auditing and financial reporting standards;

     -generally higher  commission rates on foreign  portfolio  transactions and
longer settlement periods;

     -smaller  trading  volumes and generally  lower  liquidity of foreign stock
markets, which may cause greater price volatility;

     -less  government  regulation  of  stock  exchanges,   brokers  and  listed
companies abroad than in the United States; and

     -investments  in certain  countries  may be subject to foreign  withholding
taxes,   which  may  reduce   dividend   income  or  capital  gains  payable  to
shareholders.

      There is also the possibility of expropriation  or confiscatory  taxation;
adverse  changes  in  investment  or  exchange  control  regulations;  political
instability;  potential  restrictions on the flow of international  capital; and
the possibility of a Fund  experiencing  difficulties in pursuing legal remedies
and collecting judgments.


<PAGE>





      Securities  purchased  by means of ADRs  also are not  subject  to the 25%
limitation. ADRs are receipts, typically issued by a U.S. bank or trust company,
evidencing ownership of the underlying foreign securities.  ADRs are denominated
in U.S. dollars and trade in the U.S. securities markets.  ADRs may be issued in
sponsored  or  unsponsored  programs.  In sponsored  programs,  the issuer makes
arrangements  to have its securities  traded in the form of ADRs; in unsponsored
programs,  the  issuer  may not be  directly  involved  in the  creation  of the
program.  Although the  regulatory  requirements  with respect to sponsored  and
unsponsored  programs are generally similar, the issuers of unsponsored ADRs are
not  obligated  to  disclose  material  information  in the United  States  and,
therefore,  such  information  may not be  reflected  in the market value of the
ADRs.  ADRs are  subject to certain of the same risks as direct  investments  in
foreign securities, including the risk that changes in the value of the currency
in which the  security  underlying  an ADR is  denominated  relative to the U.S.
dollar may adversely affect the value of the ADR.

Forward Foreign Currency  Contracts.  Each of the Funds may enter into contracts
to purchase or sell foreign currencies at a future date ("forward contracts") as
a hedge against fluctuations in foreign exchange rates pending the settlement of
transactions  in foreign  securities  or during the time the Funds hold  foreign
securities.  A forward contract is an agreement between  contracting  parties to
exchange  an amount of  currency  at some  future  time at an agreed  upon rate.
Although  the Funds have not adopted  any  limitations  on their  ability to use
forward contracts as a hedge against fluctuations in foreign exchange rates, the
Funds do not attempt to hedge all of their foreign investment positions and will
enter into forward contracts only to the extent,  if any, deemed  appropriate by
Fund Management.  The Funds will not enter into forward  contracts for a term of
more than one year or for purposes of speculation.  Hedging against a decline in
the value of a currency in the foregoing manner does not eliminate  fluctuations
in the prices of portfolio  securities  or prevent  losses if the prices of such
securities  decline.   Furthermore,   such  hedging  transactions  preclude  the
opportunity  for gain if the  value  of the  hedged  currency  should  rise.  No
predictions  can be made with respect to whether the total of such  transactions
will result in a better or worse position than had the Fund not entered into any
forward  contracts.  Forward  contracts  may,  from time to time,  be considered
illiquid,  in which  case they would be  subject  to the  Funds'  limitation  on
investing in illiquid  securities,  discussed above. For additional  information
regarding  forward  contracts,  see  "Investment  Policies" in the  Statement of
Additional Information.

High-Risk,  High-Yield  Securities  (Industrial Income Fund Only). Although Fund
Management  limits the  Industrial  Income Fund's debt security  investments  to
securities it believes are not highly speculative,  both credit and market risks
are increased by the Fund's  investments in debt securities  rated below the top



<PAGE>


four  grades  by  Standard  &  Poor's  or  Moody's  (high-risk,  high-yield
securities   commonly  known  as  "junk  bonds")  and  comparable  unrated  debt
securities.  Lower rated bonds by Moody's  (categories Ba, B, Caa) are of poorer
quality  and may have  speculative  characteristics.  Bonds  rated Caa may be in
default or there may be present  elements of danger with respect to principal or
interest. Lower rated bonds by Standard & Poor's (categories BB, B, CCC) include
those which are regarded, on balance, as predominantly  speculative with respect
to the issuer's  capacity to pay interest and repay principal in accordance with
their terms; BB indicates the lowest degree of speculation and CCC a high degree
of  speculation.  While such bonds will likely have some quality and  protective
characteristics,  these are  outweighed  by large  uncertainties  or major  risk
exposures to adverse conditions.

      Because  investment  in medium and lower rated  securities  involves  both
greater credit risk and market risk, achievement of the Industrial Income Fund's
investment objectives may be more dependent on Fund Management's credit analysis
than is the case for funds investing in higher quality securities.  Moreover,  a
significant  economic downturn or major increase in interest rates may result in
issuers of lower rated securities experiencing increased financial stress, which
would adversely  affect their ability to service their  principal,  dividend and
interest  obligations,  meet projected  business  goals,  and obtain  additional
financing.  In this  regard,  it should be noted  that while the market for high
yield corporate bonds has been in existence for many years and from time to time
has experienced  economic  downturns in recent years, this market has involved a
significant  increase in the use of high yield corporate debt securities to fund
highly leveraged corporate acquisitions and restructurings.  Past experience may
not, therefore, provide an accurate indication of future performance of the high
yield  bond  market,   particularly   during  periods  of  economic   recession.
Furthermore, expenses incurred to recover an investment by a Fund in a defaulted
security may adversely  affect the Fund's net asset value.  Finally,  while Fund
Management  attempts to limit purchases of medium and lower rated  securities to
securities having an established secondary market, the secondary market for such
securities may be less liquid than the market for higher quality securities. The
reduced  liquidity of the  secondary  market for such  securities  may adversely
affect the market price of, and ability of, the Industrial Income Fund to value,
particular  securities  at certain  times,  thereby  making it difficult to make
specific valuation determinations.

      While Fund  Management  continuously  monitors all of the debt  securities
held by the  Funds for the  issuers'  ability  to make  required  principal  and
interest payments and other quality factors,  a Fund may retain in the portfolio
a debt security whose rating is changed to one below the minimum rating required
for purchase.  More information on debt securities is contained in the Statement
of Additional Information.

      The following table shows the composition of the Industrial  Income Fund's
investments in corporate (and municipal) bonds by rating category for the fiscal
year ended  December 31, 1996.  All of these  percentages  were  determined on a
dollar-weighted  basis,  calculated by averaging the Fund's month-end  portfolio
holdings during the fiscal year.  These figures do not represent actual holdings
of the Fund as of December 31, 1996, nor do they imply that the overall  quality
of portfolio holdings is fixed.

Concentration  (Health  Sciences and Technology  Funds Only).  While each of the
Health  Sciences  and  Technology   Funds,  like  the  Industrial  Income  Fund,
diversifies  its  investments by investing,  with respect to at least 75% of its
total assets,  not more than 5% of its total assets in the securities of any one
issuer, its assets normally will be invested primarily in companies engaged in a
single business sector. As a result of this investment  policy, an investment in
those Funds may be subject to greater fluctuations in value than generally would
be the case if an investment  were made in an  investment  company which did not
concentrate its investments in a similar manner.  For example,  certain economic
factors or specific events may exert a  disproportionate  impact upon the prices
of equity securities of companies within a particular industry relative to their
impact on the prices of  securities  of companies  engaged in other  industries.
Additionally,  changes  in the  market  price  of  the  equity  securities  of a
particular company which occupies a dominant position in an industry may tend to
influence the market prices of other  companies  within the same industry.  As a
result of the foregoing factors,  the net asset value of the Health Sciences and
Technology  Funds may be more  susceptible  to change  than those of  investment
companies which spread their investments over many different business sectors.

      The Technology  Fund may not invest more than 25% of its total assets in a
single industry (e.g., computer software) within the technology business sector.
The Health Sciences Fund does not operate under this restriction.

Options and Futures  Contracts.  The Industrial  Income Fund may enter into
futures  contracts  for  hedging or other  non-speculative  purposes  within the
meaning and intent of  applicable  rules of  the  Commodity  Futures  Trading


<PAGE>



Commission  ("CFTC").  For example,  futures  contracts may be purchased or
sold to attempt to hedge  against  the  effects of  interest  or  exchange  rate
changes  on the  Fund's  current  or  intended  investments.  If an  anticipated
decrease in the value of  portfolio  securities  occurs as a result of a general
increase in interest rates or a change in exchange rates, the adverse effects of
such  changes may be offset,  in whole or part,  by gains on the sale of futures
contracts.  Conversely,  an increase in the cost of portfolio  securities  to be
acquired  caused by a general  decline in interest rates or a change in exchange
rates may be offset, in whole or part, by gains on futures  contracts  purchased
by the Fund.  The Fund will incur  brokerage  fees when it  purchases  and sells
futures contracts, and it will be required to maintain margin deposits.

      The Fund also may use options to buy or sell  futures  contracts  or debt
securities.  Such  investment  strategies  will be  used as a hedge  and not for
speculation.

      Put and call options on futures  contracts or securities  may be traded by
the Fund in  order to  protect  against  declines  in the  values  of  portfolio
securities  or  against  increases  in the cost of  securities  to be  acquired.
Purchases  of options on futures  contracts  may  present  less  dollar  risk in
hedging  the  Fund's  portfolio  than the  purchase  and sale of the  underlying
futures  contracts,  since the  potential  loss is  limited to the amount of the
premium plus related  transaction costs. The premium paid for such a put or call
option plus any transaction  costs will reduce the benefit,  if any, realized by
the Fund upon exercise or  liquidation of the option,  and,  unless the price of
the underlying  futures  contract  changes  sufficiently,  the option may expire
without value to the Fund.  The writing of covered  options,  however,  does not
present  less risk than the trading of futures  contracts,  and will  constitute
only a partial  hedge,  up to the amount of the  premium  received,  and,  if an
option is exercised, the Fund may suffer a loss on the transaction.

      The Fund may purchase put or call  options in  anticipation  of changes in
interest  rates or other  factors  which may  adversely  affect the value of its
portfolio or the prices of securities which the Fund anticipates purchasing at a
later  date.  The  Fund  may be able  to  offset  such  adverse  effects  on its
portfolio, in whole or in part, through the options purchased.  The premium paid
for a put or call option plus any transaction costs will reduce the benefit,  if
any,  realized by the Fund upon  exercise  or  liquidation  of the option,  and,
unless the price of the underlying security changes sufficiently, the option may
expire without value to the Fund.

      For hedging or other non-speculative  purposes, the Fund may, from time to
time, also sell ("write")  covered call options or cash secured puts in order to
attempt to increase the yield on its portfolio or to protect against declines in
the value of its  portfolio  securities.  By writing a covered call option,  the
Fund,  in return for the premium  income  realized  from the sale of the option,



<PAGE>


gives  up  the  opportunity  to  profit  from a price increase in the underlying
security above the option exercise price,  where the price increase occurs while
the option is in effect. In addition,  the Fund's ability to sell the underlying
security  will be  limited  while the  option is in  effect.  By  writing a cash
secured put, the Fund, which receives the premium, has the obligation during the
option  period,  upon  assignment of an exercise  notice,  to buy the underlying
security at a specified price. A put is secured by cash if the Fund maintains at
all times cash, Treasury bills or other high grade short-term obligations with a
value  equal to the  option  exercise  price in a  segregated  account  with its
custodian.

      Although the Fund may enter into options and futures  contracts solely for
hedging or other  non-speculative  purposes,  within the  meaning  and intent of
applicable rules of the CFTC, their use does involve certain risks. For example,
a lack of correlation between the value of an instrument underlying an option or
futures  contract and the assets  being  hedged,  or  unexpected  adverse  price
movements,  could  render the Fund's  hedging  strategy  unsuccessful  and could
result in losses. In addition, there can be no assurance that a liquid secondary
market  will  exist  for any  contract  purchased  or sold,  and the Fund may be
required to maintain a position until exercise or expiration, which could result
in losses.  Transactions  in futures  contracts and options are subject to other
risks as well.

      The risks  related to  transactions  in options  and futures to be entered
into by the Funds are set forth in greater detail in the Statement of Additional
Information,  which  should  be  reviewed  in  conjunction  with  the  foregoing
discussion.

INVESTMENT RESTRICTIONS

      Each Fund is subject to certain  fundamental  restrictions  regarding  its
investments  which  may  not be  altered  without  the  approval  of the  Fund's
shareholders. Those restrictions include, among others, limitations with respect
to the percentages of the value of the Fund's total assets which may be invested
in any one company or, with the  exception of the Health  Sciences  Fund, in one
industry. A list of each Fund's fundamental  investment  restrictions and a list
of additional,  non-fundamental  investment restrictions of each Fund (which can
be changed by the Company's board of directors without shareholder approval) are
contained in the Statement of Additional Information.

MANAGEMENT

      Pursuant to an agreement with the Company,  INVESCO, 7800 E. Union Avenue,
Denver, Colorado,  serves as the Funds' investment adviser. INVESCO is primarily
responsible  for  providing the Funds with various  administrative  services and
supervising  the Funds' daily  business  affairs.  These services are subject to
review by the Company's board of directors.



<PAGE>




      INVESCO  is  an  indirect  wholly-owned   subsidiary  of  AMVESCO  PLC,  a
publicly-traded  holding company that, through its subsidiaries,  engages in the
business of investment management on an international basis. INVESCO PLC changed
its name to AMVESCO PLC on March 3, 1997 as a part of a merger  between  INVESCO
PLC  and  A I M  Management  Group  Inc.,  thus  creating  one  of  the  largest
independent  investment management businesses in the world. Subject to obtaining
shareholder  approval at its regular Annual  Shareholder  Meeting,  the board of
directors of AMVESCO PLC has concluded that the corporate name should be changed
to AMVESCAP PLC effective  May 8, 1997.  INVESCO and INVESCO Trust will continue
to operate  under  their  existing  names.  AMVESCO PLC has  approximately  $165
billion in assets under  management.  INVESCO was established in 1932 and, as of
December  31,  1996,  managed  14  mutual  funds,   consisting  of  44  separate
portfolios,  with combined  assets of  approximately  $13.8 billion on behalf of
over 826,000 shareholders.

      Pursuant  to  agreements  with  INVESCO,   INVESCO  Trust  serves  as  the
sub-adviser  of  the  Funds.  Although  the  Company  is  not  a  party  to  any
sub-advisory agreement, the agreements have been approved for each Fund affected
by that  agreement  by the  Company's  board of  directors.  In  addition,  each
agreement has been approved as to each affected Fund by the shareholders of that
Fund.  The address of INVESCO Trust is 7800 E. Union Avenue,  Denver,  Colorado.
Subject to the  supervision  of INVESCO  and  review by the  Company's  board of
directors, INVESCO Trust is primarily responsible for selecting and managing the
investments of the Funds.

      INVESCO  Trust,  a  trust  company  founded  in  1969,  is a  wholly-owned
subsidiary  of INVESCO that served as adviser or  sub-adviser  to 55  investment
portfolios  as of December 31,  1996,  including  31  portfolios  in the INVESCO
group.  These 55 portfolios had aggregate assets of approximately  $12.7 billion
as of  December  31,  1996.  In  addition,  INVESCO  Trust  provides  investment
management  services to private clients,  including  employee benefit plans that
may be invested in a collective trust sponsored by INVESCO Trust.

      Each  Fund  pays  INVESCO a  monthly  advisory  fee which is based  upon a
percentage  of  the  Fund's  average  net  assets,  determined  daily.  For  the
Industrial Income Fund, the advisory fee is computed at the annual rate of 0.75%
on the first $500  million of the Fund's  average net assets;  0.65% on the next
$500 million of the Fund's  average net assets;  and 0.55% on the Fund's average
net assets in excess of $1  billion.  For the  Health  Sciences  and  Technology
Funds,  the advisory  fees are each computed at the annual rates of 0.75% on the
first $350  million of the Fund's  average  net  assets;  0.65% on the next $350
million of the Fund's  average net assets;  and 0.55% on the Fund's  average net
assets in excess of $700 million. For the fiscal period ended December 31, 1996,
the investment  advisory fee paid by the Industrial Income Fund was 0.75% of the
Fund's average net assets. No advisory fees are provided for the Health Sciences
and Technology Funds as they had not commenced operations as of the date of this
prospectus.

      Out of the advisory fee received from each Fund,  INVESCO pays that Fund's
sub-adviser  a  monthly  subadvisory  fee.  No fee is  paid  by any  Fund to its
sub-adviser. The sub-advisory fees for the Industrial Income Fund is computed at
the annual  rate of 0.375% on the first $500  million of the Fund's  average net
assets;  0.325% on the next $500 million of the Fund's  average net assets;  and
0.275% on the  Fund's  average  net  assets in  excess of $1  billion.  The sub-
advisory fees for the Health Sciences and Technology  Funds are each computed at



<PAGE>



the annual rates of 0.25% for the first $200 million of the Fund's  average
net assets and 0.20% on the Fund's average net assets in excess of $200 million.

      The Company also has entered  into an  Administrative  Services  Agreement
with INVESCO dated February 28, 1997 (the "Administrative Agreement").  Pursuant
to  the  Administrative  Agreement,  INVESCO  performs  certain  administrative,
recordkeeping and internal  accounting  services,  including without limitation,
maintaining  general ledger and capital stock accounts,  preparing a daily trial
balance,  calculating net asset value daily,  providing  selected general ledger
reports and providing  certain  sub-accounting  and  recordkeeping  services for
shareholder  accounts.  For  such  services,  the  Company  pays  INVESCO  a fee
consisting  of a base fee of $10,000 per year for each Fund,  plus an additional
incremental  fee  computed  at the annual rate of 0.015% per year of the average
net assets of each Fund. INVESCO also is paid a fee by the Company for providing
transfer agent services. See "Additional Information."

      Each Fund's expenses, which are accrued daily, are generally deducted from
its total income before  dividends are paid.  Total  expenses of the  Industrial
Income Fund (prior to expense  offsets)  for the fiscal year ended  December 31,
1996, including  investment advisory fees (but excluding brokerage  commissions,
which  are a cost of  acquiring  securities),  amounted  to 0.95% of the  Fund's
average net assets.  Certain Fund expenses are absorbed  voluntarily  by INVESCO
pursuant  to a  commitment  to the  Company.  This  commitment  may  be  changed
following consultation with the Company's board of directors.  If such voluntary
expense limits were not in effect, the total operating expenses, as a percentage
of each Fund's average net assets,  of the Industrial Income Fund for the fiscal
year ended December 31, 1996,  would have been 1.19%.  Total Operating  Expenses
are not provided for the Health  Sciences and  Technology  Funds as they had not
commenced operations as of the date of this prospectus.

      Fund  Management  permits  investment and other  personnel to purchase and
sell securities for their own accounts, subject to a compliance policy governing
personal investing.  This policy requires Fund Management's personnel to conduct
their personal  investment  activities in a manner that Fund Management believes
is not detrimental to the Funds or Fund Management's other advisory clients. See
"Management"  in the  Statement  of  Additional  Information  for more  detailed
information.

PURCHASES AND REDEMPTIONS

      Investors  may not purchase or redeem  shares of the Funds  directly,  but
only through  variable  annuity and variable life  insurance  contracts  offered
through the separate accounts of Participating  Insurance Companies.  A contract
owner should refer to the applicable Separate Account Prospectus for information
on how to purchase or surrender a contract, make partial withdrawals of contract


<PAGE>



values,  allocate  contract  values  to  one  or  more of the Funds,  or change
existing allocations among investment alternatives,  including the Funds. Shares
of  the  Funds  are  sold  on  a  continuous  basis  to  separate   accounts  of
Participating  Insurance  Companies by INVESCO,  as the Funds'  Distributor.  No
sales charge is imposed upon the sale of shares of the Funds.  Sales charges for
the variable  annuity or variable life insurance  contracts are described in the
Separate Account Prospectuses.  INVESCO may from time to time make payments from
its revenues to  Participating  Insurance  Companies,  broker  dealers and other
financial institutions that provide administrative services for the Funds.

      The  Participating  Insurance  Companies  place orders for their  separate
accounts  to  purchase  and  redeem  shares of each Fund based on,  among  other
things, the amount of premium payments to be invested and transfer and surrender
requests to be effected on that day  pursuant to variable  annuity and  variable
life insurance contracts. Fund shares are purchased or redeemed at the net asset
value per share next computed after receipt of a purchase or redemption order in
good form.  Payment  for  redemptions  ordinarily  will be made on behalf of the
Company and the relevant Fund by the Company's  transfer agent (INVESCO)  within
seven days after the  redemption  request is received.  However,  payment may be
postponed under unusual circumstances, such as when normal trading is not taking
place  on the  New  York  Stock  Exchange  or an  emergency  as  defined  by the
Securities and Exchange Commission exists.

      Net asset value per share is computed for each Fund once each day that the
New York Stock  Exchange  is open,  as of the close of  regular  trading on that
Exchange  (usually 4:00 p.m., New York time),  and also may be computed on other
days under  certain  circumstances.  Net asset  value per share for each Fund is
calculated by dividing the market value of the Fund's  securities plus the value
of  its  other  assets  (including   dividends  and  interest  accrued  but  not
collected),  less all liabilities (including accrued expenses), by the number of
outstanding  shares of the Fund. If market quotations are not readily available,
a security will be valued at fair value as determined in good faith by the board
of directors.  Debt securities  with remaining  maturities of 60 days or less at
the  time  of  purchase  will  be  valued  at  amortized  cost,  absent  unusual
circumstances,  so long as the Company's  board of directors  believes that such
value represents fair value.

TAX STATUS, DIVIDENDS AND DISTRIBUTIONS

Taxes. The Internal Revenue Code of 1986, as amended (the "Code"), provides that
each  investment  portfolio  of a series  fund is to be  treated  as a  separate
taxpayer.  Accordingly,  each Fund of the Company intends to continue to qualify
as a separate regulated investment company under Subchapter M of the Code.

      Each Fund intends to comply with the diversification  requirements of Code
Section  817(h).  By  meeting  this and other  requirements,  the  Participating



<PAGE>



Insurance Companies, rather  than  the  owners of  variable annuity or variable
life insurance  contracts,  should be subject to tax on  distributions  received
with respect to Fund shares. For further  information  concerning federal income
tax  consequences  for the owners of variable annuity or variable life insurance
contracts,  a  contract  owner  should  consult  his  or  her  Separate  Account
Prospectus.

      As a regulated investment company, each Fund generally will not be subject
to tax on its ordinary income and net realized  capital gains to the extent such
income and gains are  distributed  in conformity  with  applicable  distribution
requirements  under  the  Code to the  separate  accounts  of the  Participating
Insurance  Companies  which  hold its  shares.  Distributions  of income and the
excess of net  short-term  capital gain over net long-term  capital loss will be
treated as ordinary  income,  and  distributions  of the excess of net long-term
capital  gain over net  short-term  capital  loss will be treated  as  long-term
capital gain by the Participating  Insurance Companies.  Participating Insurance
Companies  should  consult  their  own  tax  advisers  concerning  whether  such
distributions  are subject to federal income tax if they are retained as part of
contract reserves.

Dividends. In addition to any increase in the value of a Fund's shares which may
occur from increases in the value of the Fund's  investments,  the Fund may earn
income in the form of dividends and interest on its investments.  Dividends paid
by each  Fund will be based  solely  on the  income  earned  by that  Fund.  The
Company's policy with respect to each Fund is to distribute substantially all of
this income,  less expenses,  to shareholders of that Fund. At the discretion of
the  board  of  directors,   distributions  are  customarily  made  annually  to
shareholders of the Funds. Dividends are automatically  reinvested in additional
shares of the Fund making the  dividend  distribution  at its net asset value on
the ex-  dividend  date,  unless an  election  is made on  behalf of a  separate
account to receive distributions in cash.

Capital  Gains.  Capital  gains or losses are the result of a Fund  selling  its
portfolio  securities at prices that are higher or lower than the prices paid by
it to purchase  such  securities.  Total gains from such sales,  less any losses
from such sales  (including  losses carried forward from prior years)  represent
net realized  capital  gains.  Each Fund  distributes  its net realized  capital
gains,  if any, to its  shareholders  at least  annually,  usually in  December.
Capital gains distributions are automatically reinvested in additional shares of
the Fund  making  the  distribution  at its net  asset  value  per  share on the
ex-dividend  date, unless an election is made on behalf of a separate account to
receive distributions in cash.

PERFORMANCE INFORMATION

      From time to time, a Fund's  total return  and/or yield may be included in
advertisements,  sales  literature,  shareholder  reports  or  Separate  Account



<PAGE>



Prospectuses.  A Fund's  total  return  and  yield  include  the  effect of
deducting  that  Fund's  expenses,  but  do not  include  charges  and  expenses
attributable  to a  particular  variable  annuity  or  variable  life  insurance
contract.  Because  shares of the Funds can be purchased only through a variable
annuity or variable life insurance  contract,  the Funds' total return and yield
data  should be reviewed  along with the  description  of  contract  charges and
expenses contained in the applicable Separate Account  Prospectus.  Total return
or yield for a Fund must always be accompanied by, and reviewed with, comparable
total return or yield data for an associated  variable annuity separate account,
or data that would permit evaluation of the magnitude of variable life insurance
charges and  expenses not  reflected  in the Fund's total return or yield.  Fund
total  return and yield  figures are based upon  historical  results and are not
intended to indicate future performance.

      The "total  return" of a Fund refers to the average  annual rate of return
of an  investment  in the Fund.  This  figure is  computed  by  calculating  the
percentage change in value of an investment of $1,000,  assuming reinvestment of
all income dividends and capital gain  distributions,  to the end of a specified
period.  "Total  return"  quotations  reflect  the  performance  of the Fund and
include the effect of capital changes.

      The total return performance for the Industrial Income Fund for the fiscal
period ended December 31, 1996, was 22.28%.

      The yield of the Fund is  calculated  by utilizing  the Fund's  calculated
income,  expenses and average  outstanding  shares for the most recent 30-day or
one-month  period,  dividing it by the month end net asset value and annualizing
the resulting number.

      In conjunction  with  performance  reports and/or  analyses of shareholder
service for the Fund,  comparisons of the Fund's  performance for a given period
to the  performance  of recognized  indices and for the same period may be made.
Such indices  include ones  provided by Dow Jones & Company,  Standard & Poor's,
Lipper  Analytical  Services,  Inc.,  Lehman Brothers,  National  Association of
Securities Dealers,  Inc., Frank Russell Company,  Value Line Investment Survey,
the American Stock  Exchange,  Morgan Stanley  Capital  International,  Wilshire
Associates,  the Financial  Times- Stock Exchange,  the New York Stock Exchange,
the  Nikkei  Stock  Average  and the  Deutcher  Aktienindex,  all of  which  are
unmanaged  market  indicators.  Such  comparisons can be a useful measure of the
quality of the Funds' investment performance.  However, because Fund performance
data does not reflect  separate account and contract  charges,  Fund performance
data is not an  appropriate  measure of the  performance  of a contract  owner's
investment in the variable annuity and variable life insurance contracts.

      In addition,  rankings, ratings, and comparisons of investment performance
and/or   assessments  of  the  quality  of  shareholder   service  appearing  in
publications such as Money,  Forbes,  Kiplinger's  Personal Finance,  Financial



<PAGE>



World, Morningstar,  and  similar  sources  which  utilize information compiled
(i)  internally;  (ii) by Lipper  Analytical  Services,  Inc.; or (iii) by other
recognized  analytical  services,  may be used in sales  literature.  The Lipper
Analytical  Services,  Inc.  rankings and comparisons,  which may be used by the
Funds in  performance  reports,  will be drawn from the  "Equity  Income  Funds"
variable  insurance  product  grouping  for  the  Industrial  Income  Fund,  the
"Health/Biotechnology  Funds"  grouping  for the  Health  Sciences  Fund and the
"Science and Technology  Funds"  grouping for the Technology  Fund. In addition,
the broad-based  Lipper  variable  insurance  product  groupings may be used for
comparison to any of the Funds. A more complete list of publications that may be
quoted in sales  literature is contained under the caption  "Performance" in the
Statement of Additional Information.

ADDITIONAL INFORMATION

Voting  Rights.  The  Participating   Insurance  Companies  and  their  separate
accounts,  rather than individual  contract owners,  are the shareholders of the
Funds.  However,  each Participating  Insurance Company will vote shares held by
its separate accounts as required by law and interpretations thereof, as amended
or changed from time to time. In accordance with current law and interpretations
thereof,  a  Participating  Insurance  Company is  required  to  request  voting
instructions  from its contract owners and must vote Fund shares held by each of
its  separate  accounts  in  proportion  to the  voting  instructions  received.
Additional  information about voting procedures  (including a discussion,  where
applicable,  of circumstances under which some Participating Insurance Companies
may vote Fund shares held by variable life  insurance  separate  accounts  other
than in  accordance  with  contract  owner  instructions)  is  contained  in the
applicable Separate Account Prospectuses.

      All shares of the Funds have equal voting rights.  When  shareholders  are
entitled  to vote upon a matter,  each  shareholder  is entitled to one vote for
each share owned and a corresponding  fractional vote for each fractional  share
owned.  Voting  with  respect  to  certain  matters,  such  as  ratification  of
independent  accountants and the election of directors,  will be by all Funds of
the Company voting together.  In other cases,  such as voting upon an investment
advisory contract, voting is on a Fund-by-Fund basis. To the extent permitted by
law,  when not all  Funds  are  affected  by a matter  to be  voted  upon,  only
shareholders  of the Fund or Funds  affected  by the matter  will be entitled to
vote thereon.  The Company is not generally required and does not expect to hold
regular annual meetings of  shareholders.  However,  the board of directors will
call special meetings of shareholders for the purpose,  among other reasons,  of
voting upon the question of removal of a director or directors when requested to
do so in writing by the holders of 10% or more of the outstanding  shares of the
Company or as may be required by  applicable  law or the  Company's  Articles of
Incorporation.  The Company will assist shareholders in communicating with other
shareholders as required by the Investment Company Act of 1940. Directors may be



<PAGE>



removed by action of the holders of a majority  or more of the  outstanding
shares of the Company.

Shareholder  Inquiries.  Inquiries  regarding  the Funds may be  directed to the
Company at the telephone  number or mailing  address set forth on the cover page
of this Prospectus or to a Participating Insurance Company.

Transfer and Disbursing  Agent.  INVESCO acts as registrar,  transfer agent, and
dividend  disbursing  agent  for  the  Company  pursuant  to a  Transfer  Agency
Agreement that provides for an annual fee of $5,000 per Fund.

Master/Feeder  Option.  The Company may in the future seek to achieve any Fund's
investment  objective  by  investing  all  of  that  Fund's  assets  in  another
investment  company having the same investment  objective and  substantially the
same investment  policies and  restrictions as those applicable to that Fund. It
is  expected  that any such  investment  company  would be managed by INVESCO in
substantially  the same manner as the existing  Fund. If permitted by applicable
laws and policies then in effect,  any such  investment  may be made in the sole
discretion of the Company's board of directors  without further  approval of the
Funds' shareholders.  However,  Fund shareholders will be given at least 30 days
prior notice of any such  investment.  Such investment would be made only if the
Company's board of directors determines it to be in the best interests of a Fund
and its  shareholders.  In making that  determination,  the board will consider,
among other  things,  the benefits to  shareholders  and/or the  opportunity  to
reduce costs and achieve  operational  efficiencies.  No assurance is given that
costs will be materially reduced if this option is implemented.

NO  PERSON  HAS  BEEN  AUTHORIZED  TO  GIVE  ANY  INFORMATION  OR  TO  MAKE  ANY
REPRESENTATIONS  NOT  CONTAINED  IN  THIS  PROSPECTUS,  OR IN THE  STATEMENT  OF
ADDITIONAL INFORMATION  INCORPORATED HEREIN BY REFERENCE, IN CONNECTION WITH THE
OFFERING MADE BY THIS  PROSPECTUS  AND, IF GIVEN OR MADE,  SUCH  INFORMATION  OR
PRESENTATIONS  MUST NOT BE RELIED UPON AS HAVING BEEN AUTHORIZED BY THE COMPANY.

BOND RATINGS

      The  following  is a  description  of Standard & Poor's and  Moody's  bond
rating categories:

Standard & Poor's Corporate Bond Ratings

      AAA - This is the highest  rating  assigned by Standard & Poor's to a debt
obligation  and  indicates an extremely  strong  capacity to pay  principal  and
interest.

      AA - Bonds  rated  AA  also  qualify  as  high-quality  debt  obligations.
Capacity to pay  principal  and interest is very strong,  and in the majority of
instances they differ from AAA issues only in small degree.

      A - Bonds rated A have a strong  capacity to pay  principal  and interest,
although they are somewhat more susceptible to the adverse effects of changes in
circumstances and economic conditions than bonds in higher rated categories.

      BBB - Bonds rated BBB are regarded as having an adequate capability to pay
principal  and  interest.  Whereas they  normally  exhibit  adequate  protection
parameters,  adverse  economic  conditions  or changing  circumstances  are more
likely to lead to a weakened capacity to pay principal and interest for bonds in
this category than for bonds in higher rated categories.

      BB - Bonds  rated BB have less  near-term  vulnerability  to default  than
other  speculative  issues.  However,  they face major ongoing  uncertainties or
exposure to adverse business, financial, or economic conditions which could lead
to inadequate capacity to meet timely interest and principal payments.

      B - Bonds rated B have a greater  vulnerability  to default but  currently
have the capacity to meet interest  payments and principal  repayments.  Adverse
business,  financial,  or economic  conditions  will likely  impair  capacity or
willingness to pay interest and repay principal.

      CCC - Bonds  rated  CCC have a  currently  identifiable  vulnerability  to
default and are  dependent  upon  favorable  business,  financial,  and economic
conditions to meet timely payment of interest and repayment of principal. In the
event of adverse  business,  financial,  or  economic  conditions,  they are not
likely to have the capacity to pay interest and repay principal.




<PAGE>



Moody's Corporate Bond Ratings

      Aaa - Bonds rated Aaa are judged to be of the best quality. They carry the
smallest   degree  of  investment   risk  and  are  generally   referred  to  as
"gilt-edged."  Interest payments are protected by a large or by an exceptionally
stable margin, and principal is secure.  While the various  protective  elements
are likely to change,  such changes as can be  visualized  are most  unlikely to
impair the fundamentally strong position of such issues.

      Aa - Bonds  rated Aa are judged to be of high  quality  by all  standards.
Together with the Aaa group,  they  comprise  what are  generally  known as high
grade  bonds.  They are rated  lower  than the best  bonds  because  margins  of
protection may not be as large as in Aaa securities or fluctuation of protective
elements  may be of greater  amplitude  or there may be other  elements  present
which make the long term risk appear somewhat larger than in Aaa securities.

      A - Bonds rated A possess many favorable investment attributes, and are to
be  considered as upper medium grade  obligations.  Factors  giving  security to
principal and interest are considered adequate but elements may be present which
suggest a susceptibility to impairment sometime in the future.

      Baa - Bonds rated Baa are  considered as medium grade  obligations,  i.e.,
they are neither  highly  protected nor poorly  secured.  Interest  payments and
principal  security  appear  adequate  for the present  but  certain  protective
elements may be lacking or may be  characteristically  unreliable over any great
length of time. Such bonds lack outstanding  investment  characteristics  and in
fact have speculative characteristics as well.

      Ba - Bonds rated Ba are judged to have speculative elements.  Their future
cannot be  considered  as well  assured.  Often the  protection  of interest and
principal  payments may be very moderate and thereby not well safeguarded during
both good and bad times over the future.  Uncertainty of position  characterizes
bonds in this class.

      B -  Bonds  rated  B  generally  lack  characteristics  of  the  desirable
investment. Assurance of interest and principal payments or maintenance of other
terms of the contract over any longer period of time may be small.

      Caa - Bonds rated Caa are of poor standing.  Such issues may be in default
or there may be  present  elements  of  danger  with  respect  to  principal  or
interest.
