             RE: PROPOSED FUND REORGANIZATIONS

Dear Directors and Trustees:

         You have requested our opinion about certain United States Federal
income tax consequences of the reorganization of each of the five investment
portfolios of GT Global Variable Investment Series ("GT Series") and each of the
nine investment portfolios of GT Global Variable Investment Trust ("GT Trust")
(collectively, the "Acquired Funds") into a corresponding portfolio of AIM
Variable Insurance Funds, Inc. (collectively, the "Acquiring Funds").

         We are rendering this opinion in connection with the transaction
described in the Agreement and Plan of Reorganization (the "Agreement") by and
among (a) GT Series and GT Trust (collectively, the "GT Funds"), acting on
behalf of each of their respective and separate series, (b) AIM Variable
Insurance Funds, Inc. ("AVIF"), acting on behalf of each of certain of its
series, and (c) A I M Advisors, Inc., ("AIM"), as entered into as of June 23,
1999. We adopt the applicable terms in the Agreement.

         This opinion is for delivery to the Acquired Funds, the Acquiring
Funds, and their applicable shareholders. Only the Acquired Funds, the Acquiring
Funds, and their applicable shareholders may rely on this opinion.


Facts

         In rendering this opinion, we have assumed the truth and accuracy of
the following:
   2

         GT Series and GT Trust are each a business trust under Delaware law and
an open-end management investment company operating as a series fund under the
Investment Company Act of 1940 ("1940 Act"). AVIF is a corporation under
Maryland law and an open-end management investment company operating as a series
fund under the 1940 Act. Each of the Acquired Funds and each of the Acquiring
Funds (except for AIM V.I. Global Growth and Income Fund and AIM V.I.
Telecommunications Fund, which, as of this date, have not commenced operations)
is taxed as a separate regulated investment company ("RIC") under Subchapter M
of the Internal Revenue Code of 1986, as amended ("Code").

         Shares of each of the Acquired Funds and the Acquiring Funds (except
for AIM V.I. Global Growth and Income Fund and AIM V.I. Telecommunications Fund,
which, as of this date, have not commenced operations) are sold exclusively to
separate accounts of life insurance companies (the "separate accounts") in
connection with the sale by those companies of variable annuity contracts and
variable life insurance contracts ("Contracts") to "Contract Owners," and the
payment by those Contract Owners of initial and additional premiums to those
companies for those Contracts. Accordingly, with the exception of certain "seed
money" invested by AIM Advisors, Inc. in certain of the Acquiring Funds, all
shares of the Acquired and Acquiring Funds (except for AIM V.I. Global Growth
and Income Fund and AIM V.I. Telecommunications Fund, which, as of this date,
have not commenced operations) are owned by separate accounts of life insurance
companies.


Proposed Transaction

         The Agreement contemplates the following transaction for each Acquired
Fund. Each transaction will constitute a separate "Reorganization" under the
Code:

         (a)      the acquisition of substantially all of the assets and the
                  assumption of all of the liabilities of each of the Acquired
                  Funds by the corresponding Acquiring Fund, as set forth in the
                  following table, in exchange solely for shares of voting stock
                  of those Acquiring Funds (the "voting stock");

         (b)      the distribution of that voting stock to shareholders of the
                  corresponding Acquired Fund; and

         (c)      the termination of each Acquired Fund as a series of either
                  the GT Series or the GT Trust.

         Each shareholder of an Acquired Fund will receive that number of the
corresponding Acquiring Fund voting stock representing interests with an
aggregate net asset value equal to the aggregate net asset value of its shares
of the Acquired Fund ("Acquired Fund shares").


Representations

         In rendering our opinion, we have examined and relied on the truth and
accuracy of the Agreement and such other documents, records, and instruments as
we have deemed necessary to enable us to render the opinion. In addition, we
have relied on the following representations of GT Funds and AVIF, as set forth
in the Agreement and in the proxy statement/prospectus included in the
registration statement that AVIF will file with the SEC on Form N-14 under the
Securities Act of 1933, that the following facts and circumstances will exist as
of the applicable closing date of each Reorganization ("Closing Date"):

         (A)      The fair market value of the voting stock of each Acquiring
                  Fund received by each shareholder of a corresponding Acquired
                  Fund will be approximately equal to the fair market value of
                  the Acquired Fund shares that such shareholder held before
                  the Reorganization.

         (B)      There is no plan or intention by the shareholders of any of
                  the Acquired Funds to redeem a number of shares of the voting
                  stock of a corresponding Acquiring Fund received in the
                  Reorganization that would reduce an Acquired Fund
                  shareholder's ownership of the voting stock to a number of
                  shares having a value, as of the Closing Date, of less than
                  50% of the value of all of the formerly outstanding





   4
                  Acquired Fund shares as of the Closing Date. In the case of GT
                  Global Variable Growth & Income Fund and GT Global Variable
                  Telecommunications Fund, "100 percent" shall be substituted
                  for "50 percent" if the corresponding Acquiring Fund has not
                  commenced operations or issued voting stock (other than to its
                  investment adviser in connection with its creation) prior to
                  the Closing Date.

         (C)      Following the Reorganizations, each Acquiring Fund will
                  continue the historic business of the corresponding Acquired
                  Fund or use a significant portion of such Acquired Fund's
                  historic business assets in its business.

         (D)      At the direction of each of the Acquired Funds, each
                  corresponding Acquiring Fund will issue directly to each
                  Acquired Fund's shareholders pro rata the voting stock that
                  each Acquired Fund constructively receives in the
                  Reorganization, and each Acquired Fund will distribute its
                  other properties (if any) to its shareholders, on or as
                  promptly as practicable after the Closing Date.

         (E)      No Acquiring Fund has any plan or intention to reacquire any
                  of its voting stock issued in the Reorganization, except to
                  the extent that the Acquiring Fund is required by the 1940 Act
                  to redeem any of its shares of voting stock presented for
                  redemption.

         (F)      No Acquiring Fund plans or intends to sell or otherwise
                  dispose of any of the assets of the corresponding Acquired
                  Fund acquired in the Reorganization, except for dispositions
                  made in the ordinary course of its business or dispositions
                  necessary to maintain its status as a RIC under the Code.

         (G)      Each Acquiring Fund, each Acquired Fund, and each shareholder
                  of each Acquired Fund will pay its respective expenses, if
                  any, incurred in connection with the Reorganization.

         (H)      Each Acquiring Fund will acquire at least 90 percent of the
                  fair market value of the net assets, and at least 70 percent
                  of the fair market value of the gross assets, held by each
                  corresponding Acquired Fund immediately before the
                  Reorganization, including for this purpose any amounts used by
                  the Acquired Fund to pay its Reorganization expenses and all
                  redemptions and distributions made by the Acquired Fund
                  immediately before the Reorganization (other than redemptions
                  pursuant to a demand of a shareholder in the ordinary course
                  of the Acquired Fund's business as a series of an open-end
                  management investment company under the 1940 Act and regular,
                  normal dividends not in excess of the requirements of Section
                  852 of the Code). This representation does not apply to AIM
                  V.I. Global Growth and Income Fund or AIM V.I.
                  Telecommunications Fund, if, in the case of each such Fund,
                  the Fund has not commenced operations or issued voting stock
                  (other than to its investment adviser in connection with its
                  creation) prior to the Closing Date.




   5

         (I)      Each Acquiring Fund (except for either AIM V.I. Global Growth
                  and Income Fund or AIM V.I. Telecommunications Fund if, in the
                  case of such Fund, the Fund has not commenced operations or
                  issued voting stock (other than to its investment adviser in
                  connection with its creation) prior to the Closing Date) and
                  each Acquired Fund has elected to be taxed as a RIC under
                  Section 851 of the Code and will each have qualified for the
                  special Federal tax treatment afforded RICs under the Code for
                  all taxable periods. These taxable periods include the taxable
                  year of each Acquiring Fund that includes the Closing Date and
                  the last short taxable period of each Acquired Fund ending on
                  the Closing Date (except for GT Global Variable Growth &
                  Income Fund or GT Global Variable Telecommunications Fund, if,
                  in the case of such Fund, the corresponding Acquiring Fund has
                  not commenced operations or issued voting stock (other than to
                  its investment adviser in connection with its creation prior
                  to the Closing Date)).

         (J)      The liabilities of each Acquired Fund assumed by the
                  corresponding Acquiring Fund and the liabilities to which the
                  transferred assets of each Acquired Fund are subject were
                  incurred by the Acquired Fund in the ordinary course of its
                  business.

         (K)      There is no intercorporate indebtedness existing between any
                  Acquiring Fund and a corresponding Acquired Fund that was
                  issued, acquired, or will be settled at a discount.

         (L)      No Acquiring Fund owns, directly or indirectly, nor has it
                  owned during the past five years, directly or indirectly, any
                  shares of an Acquired Fund from which it is receiving assets
                  in the Reorganization.

         (M)      The fair market value of the assets of each Acquired Fund
                  transferred to the corresponding Acquiring Fund will equal or
                  exceed the sum of the liabilities assumed by the corresponding
                  Acquiring Fund, plus the amount of liabilities, if any, to
                  which the transferred assets are subject.

         (N)      No Acquired Fund is under the jurisdiction of a court in a
                  United States Code Title 11 or similar case within the meaning
                  of Section 368(a)(3)(A) of the Code.

         (O)      Not more than 25 percent of the value of the total assets of
                  any Acquiring Fund or any Acquired Fund or any Acquired Fund
                  has been, is, or will be invested in the stock or securities
                  of any one issuer, and not more than 50 percent of the value
                  of the total assets of any Acquiring Fund or any Acquired Fund
                  has been, is, or will be invested in the stock or securities
                  of five or fewer issuers.

         (P)      Each Acquiring Fund and each Acquired Fund will have satisfied
                  the investment diversification requirements of Section 817(h)
                  of the Code for all taxable quarters since its inception,
                  including the last short taxable period of each Acquired Fund
                  ending on the Closing Date and taxable quarter of each
                  Acquiring Fund that includes the Closing Date. In the case of
                  GT Global Variable Growth & Income



   6

                  Fund and GT Global Variable Telecommunications Fund, if the
                  corresponding Acquiring Fund has not commenced operations or
                  issued voting stock (other than to its investment adviser in
                  connection with its creation) prior to the Closing Date, "last
                  short taxable period" shall read "taxable quarter."

         (Q)      Immediately following the Reorganizations, the shareholders of
                  GT Global Variable Growth & Income Fund and GT Global Variable
                  Telecommunications Fund will own all of the outstanding voting
                  stock of the corresponding Acquiring Funds and will own such
                  stock solely by reason of their ownership of GT Global
                  Variable Growth & Income Fund and GT Global Variable
                  Telecommunications Fund, where the corresponding Acquiring
                  Fund has not commenced operations or issued voting stock
                  (other than to its investment adviser in connection with its
                  creation) prior to the Closing Date.

         (R)      Immediately following the Reorganizations, either AIM V.I.
                  Global Growth and Income Fund or AIM V.I. Telecommunications
                  Fund will, if it has not commenced operations or issued voting
                  stock (other than to its investment adviser in connection with
                  its creation) prior to the Closing Date, possess the same
                  assets and liabilities, except for assets used to pay expenses
                  incurred in the Reorganizations, as those possessed by the
                  corresponding Acquired Funds immediately prior to the
                  Reorganizations.


Opinion

         Solely based on the foregoing facts, assumptions, and representations,
and our consideration of other questions we have deemed necessary or appropriate
for such purposes, and based on the assumption that the Reorganizations are
consummated in accordance with the terms of the Agreement, we are of the opinion
that, under current United States Federal income tax laws and regulations,
including official interpretations of the laws, in effect as of this date:

         (1)      The transfer of the assets of each Acquired Fund to each
                  corresponding Acquiring Fund in exchange for voting stock of
                  the Acquiring Fund distributed directly to the shareholders of
                  the Acquired Fund, as provided in the Agreement, will
                  constitute a "reorganization" within the meaning of Section
                  368(a)(1) of the Code, and each Acquired Fund and each
                  Acquiring Fund will be a "party to a reorganization" within
                  the meaning of Section 368(b) of the Code.

         (2)      In accordance with Section 361(a) and Section 361(c)(1) of the
                  Code, no gain or loss will be recognized by an Acquired Fund
                  on the transfer of its assets to the corresponding Acquiring
                  Fund solely in exchange for voting stock of the Acquiring Fund
                  and the Acquiring Fund's assumption of the Acquired Fund's
                  liabilities, or on the distribution of the voting stock to the
                  Acquired Fund's shareholders.




   7

         (3)      In accordance with Section 1032 of the Code, no gain or loss
                  will be recognized by any Acquiring Fund on the receipt of
                  assets of its corresponding Acquired Fund in exchange for
                  Acquiring Fund voting stock and the Acquiring Fund's
                  assumption of the Acquired Fund's liabilities.

         (4)      In accordance with Section 354(a)(1) of the Code, no gain or
                  loss will be recognized by shareholders of any Acquired Fund
                  on the receipt of voting stock of the corresponding Acquiring
                  Fund in constructive exchange for their Acquired Fund shares.

         (5)      In accordance with Section 362(b) of the Code, the basis to
                  each Acquiring Fund of the assets of each corresponding
                  Acquired Fund transferred to it will be the same as the basis
                  of those assets in the hands of such Acquired Fund immediately
                  before the Reorganization.

         (6)      In accordance with Section 358(a) of the Code, an Acquired
                  Fund shareholder's basis for voting stock of the corresponding
                  Acquiring Fund received by the Acquired Fund shareholder will
                  be the same as the Acquired Fund shareholder's basis for
                  Acquired Fund shares constructively exchanged therefor.

         (7)      In accordance with Section 1223(1) of the Code, an Acquired
                  Fund shareholder's holding period for voting stock of a
                  corresponding Acquiring Fund will include the Acquired Fund
                  shareholder's holding period for the Acquired Fund shares
                  constructively exchanged therefor, provided that the Acquired
                  Fund shareholder held the Acquired Fund shares as a capital
                  asset.

         (8)      In accordance with Section 1223(2) of the Code, the holding
                  period for assets of an Acquired Fund transferred to its
                  corresponding Acquiring Fund in the Reorganizations will
                  include the holding period for those assets in the hands of
                  the Acquired Fund.

         (9)      For purposes of Section 381 of the Code, AIM V.I. Global
                  Growth and Income Fund and AIM V.I. Telecommunications Fund
                  will each be treated as if there had been no Reorganization,
                  if, in the case of each such Fund, the Fund has not commenced
                  operations or issued voting stock (other than to its
                  investment adviser in connection with its creation) prior to
                  the Closing Date.

         (10)     Each Acquired Fund and each corresponding Acquiring Fund will
                  be a RIC under Subchapter M and will comply with the
                  investment diversification requirements of Section 817(h) of
                  the Code. Accordingly, the Reorganizations will not produce
