                          INVESTMENT ADVISORY AGREEMENT


      AGREEMENT made this 1st day of February, 1998, and amended and restated as

which has assumed its duties under this Agreement (the "Advisor").

                                   WITNESSETH:

      WHEREAS,  the  Trust has been  organized  and  intends  to  operate  as an
investment  company  registered under the Investment  Company Act of 1940 ("1940
Act") and is currently  comprised of four series, one of which is the Portfolio;
and each series will engage in the business of  investing  and  reinvesting  its
assets; and

      WHEREAS,  the  Advisor  is  a  registered  investment  adviser  under  the
Investment  Advisers  Act of 1940  and  engages  in the  business  of  providing
investment advisory services; and

      WHEREAS,  the  Trust's  Board of  Trustees,  including  a majority  of the
Trustees  who are not parties to this  Agreement  or  "interested  persons"  (as
defined  in the  1940  Act)  of any  such  party,  and the  Portfolio's  initial
shareholder have approved this Agreement;

      NOW,  THEREFORE,  in  consideration  of the mutual promises and agreements
herein contained and other good and valuable consideration, the receipt of which
is hereby acknowledged, it is hereby agreed by and between the parties hereto as
follows:

      1.    In General

      The  Advisor  agrees,  all as  more  fully  set  forth  herein,  to act as
managerial investment advisor to the Trust with respect to the investment of the
assets of the  Portfolio  and to supervise  and arrange the purchase and sale of
securities held in the portfolio of the Portfolio.

      2.    Duties and  Obligations of the Advisor with respect to Investment of
            Assets of the Portfolio

            (a) Subject to the succeeding provisions of this section and subject
            to the  direction and control of the Board of Trustees of the Trust,
            the Advisor shall:



                  (i) Decide what  securities or other assets shall be purchased
                  or sold by the Trust with respect to the  Portfolio  and when;
                  and

                  (ii) Arrange for the purchase  and the sale of  securities  or
                  other assets held in the portfolio of the Portfolio by placing
                  purchase  and sale  orders for the Trust  with  respect to the
                  Portfolio.

            (b) Any  investment  purchases or sales made by the Advisor shall at
            all times conform to, and be in accordance  with,  any  requirements
            imposed by: (1) the  provisions  of the 1940 Act and of any rules or
            regulations in force thereunder; (2) any other applicable provisions
            of law; (3) the  provisions of the  Declaration of Trust and By-Laws
            of the Trust as  amended  from time to time;  (4) any  policies  and
            determinations  of the Board of Trustees  of the Trust;  and (5) the
            fundamental  policies  of the Trust  relating to the  Portfolio,  as
            reflected in the Trust's Registration  Statement under the 1940 Act,
            or as amended by the shareholders of the Portfolio.

            (c) The  Advisor  shall  give  the  Trust  the  benefit  of its best
            judgment and effort in rendering services hereunder, but the Advisor
            shall  not be  liable  for  any  loss  sustained  by  reason  of the
            purchase,  sale or  retention  of any  security  whether or not such
            purchase,  sale  or  retention  shall  have  been  based  on its own
            investigation  and research or upon  investigation and research made
            by any other individual, firm or corporation, if such purchase, sale
            or retention shall have been made and such other individual, firm or
            corporation  shall have been selected in good faith.  Nothing herein
            contained  shall,  however,  be  construed  to protect  the  Advisor
            against any liability to the Trust or its security holders by reason
            of  willful  misfeasance,  bad  faith,  or gross  negligence  in the
            performance of its duties, or by reason of its reckless disregard of
            obligations and duties under this Agreement.

            (d)  Nothing in this  Agreement  shall  prevent  the  Advisor or any
            affiliated  person (as defined in the 1940 Act) of the Advisor  from
            acting as investment advisor or manager and/or principal underwriter
            for any other person,  firm or corporation  and shall not in any way
            limit or  restrict  the Advisor or any such  affiliated  person from
            buying,  selling  or  trading  any  securities  for its or their own
            accounts  or the  accounts  of  others  for  whom it or they  may be
            acting,  provided,  however,  that the Advisor expressly  represents
            that it will undertake no activities  which,  in its judgment,  will
            adversely  affect the  performance  of its  obligations to the Trust
            under this Agreement.

            (e) It is agreed that the Advisor  shall have no  responsibility  or
            liability   for  the  accuracy  or   completeness   of  the  Trust's
            Registration  Statement  under the 1940 Act or the Securities Act of
            1933 except for  information  supplied by the Advisor for  inclusion
            therein.  The Trust may  indemnify  the  Advisor to the full  extent
            permitted by the Trust's Declaration of Trust.


                                       2


      3.    Broker-Dealer Relationships

      The Advisor is  responsible  for decisions to buy and sell  securities for
the Portfolio,  broker-dealer selection, and negotiation of brokerage commission
rates. The Advisor's primary consideration in effecting a securities transaction
will be execution at the most favorable  price. In selecting a broker-dealer  to
execute each  particular  transaction,  the Advisor will take the following into
consideration:  the best net price  available;  the  reliability,  integrity and
financial  condition  of  the  broker-dealer;  the  size  of and  difficulty  in
executing  the  order;  and  the  value  of  the  expected  contribution  of the
broker-dealer  to the  investment  performance  of the Portfolio on a continuing
basis.  Accordingly,  the price to the Portfolio in any  transaction may be less
favorable than that available  from another  broker-dealer  if the difference is
reasonably  justified  by other  aspects  of the  portfolio  execution  services
offered.  Subject to such  policies  as the Board of  Trustees  of the Trust may
determine,  the Advisor shall not be deemed to have acted  unlawfully or to have
breached any duty created by this Agreement or otherwise solely by reason of its
having caused the Portfolio to pay a broker or dealer that provides brokerage or
research  services  to the  Advisor  an amount of  commission  for  effecting  a
portfolio  transaction  in excess of the amount of commission  another broker or
dealer  would have  charged  for  effecting  that  transaction,  if the  Advisor
determines  in good faith  that such  amount of  commission  was  reasonable  in
relation to the value of the  brokerage and research  services  provided by such
broker or dealer,  viewed in terms of either that particular  transaction or the
Advisor's  overall  responsibilities  with respect to the Trust.  The Advisor is
further  authorized  to  allocate  the  orders  placed  by it on  behalf  of the
Portfolio to such brokers or dealers who also  provide  research or  statistical
material,  or other  services,  to the Trust,  the Advisor,  or any affiliate of
either.  Such allocation shall be in such amounts and proportions as the Advisor
shall determine,  and the Advisor shall report on such allocations  regularly to
the Trust, indicating the broker-dealers to whom such allocations have been made
and the basis  therefor.  The Advisor is also  authorized  to consider  sales of
shares as a factor in the  selection of brokers or dealers to execute  portfolio
transactions,  subject to the  requirements of best  execution,  i.e., that such
brokers  or  dealers  are able to  execute  the order  promptly  and at the best
obtainable securities price.

      4.    Allocation of Expenses

      The  Advisor  agrees  that it will  furnish  the Trust,  at the  Advisor's
expense,  with all office  space and  facilities,  and  equipment  and  clerical
personnel  necessary  for  carrying  out its duties  under this  Agreement.  The
Advisor  (or an  affiliate  thereof)  will  also  pay  all  compensation  of all
Trustees,  officers and employees of the Trust who are affiliated persons of the
Advisor.  All  operating  costs  and  expenses  relating  to the  Portfolio  not
expressly assumed by the Advisor under this Agreement shall be paid by the Trust
from the assets of the Portfolio, as applicable,  including,  but not limited to
(i) interest and taxes; (ii) brokerage  commissions;  (iii) insurance  premiums;
(iv)  compensation  and  expenses  of the  Trust's  Trustees  other  than  those
affiliated  with the  Advisor;  (v)  legal  and  audit  expenses;  (vi) fees and
expenses of the Trust's custodian,  shareholder  servicing or transfer agent and
accounting  services  agent;  (vii)  expenses  incident  to the  issuance of the
Portfolio's  shares,  including  issuance on the payment of, or reinvestment of,
dividends;  (viii) fees and expenses incident to the registration  under Federal
or state  securities  laws of the  Trust or the  shares of the  Portfolio;  (ix)
expenses  of  preparing,  printing  and  mailing


                                       3


reports and notices and proxy materials to  shareholders  of the Portfolio;  (x)
all other expenses incident to holding meetings of the Portfolio's shareholders;
(xi) dues or assessments of or contributions to the Investment Company Institute
or any  successor;  (xii) such  non-recurring  expenses as may arise,  including
litigation  affecting  the Trust and the legal  obligations  which the Trust may
have to indemnify its officers and Trustees with respect thereto; and (xiii) all
expenses  which the  Trust or the  Portfolio  agree to bear in any  distribution
agreement or in any plan adopted by the Trust and/or the  Portfolio  pursuant to
Rule 12b-1 under the 1940 Act.

      5.    Compensation of the Advisor

      The Trust  agrees to pay the Advisor  and the Advisor  agrees to accept as
full compensation for all services rendered by the Advisor hereunder,  an annual
management  fee,  payable  monthly and  computed on the value of the average net
assets of the  Portfolio as of the close of business  each  business day, at the
annual rate of .55%.

      6.    Duration and Termination

            (a) This  Agreement  shall go into  effect  on the date  hereof  and
            shall, unless terminated as hereinafter provided, continue in effect
            until February 1, 2000,  and thereafter  from year to year, but only
            so  long as such  continuance  is  specifically  approved  at  least
            annually by the Trust's  Board of Trustees,  including the vote of a
            majority of the  Trustees  who are not parties to this  Agreement or
            "interested  persons" (as defined in the 1940 Act) of any such party
            cast in person at a meeting called for the purpose of voting on such
            approval,  or by the  vote of the  holders  of a  "majority"  (as so
            defined) of the outstanding  voting  securities of the Portfolio and
            by such a vote of the Trustees.

            (b) This  Agreement  may be  terminated  by the  Advisor at any time
            without  penalty  upon  giving the Trust  sixty  (60) days'  written
            notice  (which  notice  may be  waived  by  the  Trust)  and  may be
            terminated by the Trust at any time without  penalty upon giving the
            Advisor sixty (60) days' written  notice (which notice may be waived
            by the Advisor),  provided that such  termination by the Trust shall
            be  directed  or  approved  by the vote of a majority  of all of its
            Trustees  in office at the time or by the vote of the  holders  of a
            majority  (as defined in the 1940 Act) of the voting  securities  of
            the  Trust at the  time  outstanding  and  entitled  to  vote.  This
            Agreement  shall  automatically   terminate  in  the  event  of  its
            assignment (as so defined).

      7.    Use of Advisor's Name

      The Trust may use the name "Hotchkis and Wiley Variable Trust" or any name
including the words  "Hotchkis and Wiley" only for so long as this  Agreement or
any  other  advisory  agreement  relating  to the  Trust  is in  effect.  If the
Agreement or any other advisory  agreement relating to the Trust is no longer in
effect,  the Trust will (to the extent that it lawfully can) cease to use such a
name or any other name indicating  that it is advised by or otherwise  connected
with


                                       4


the Advisor,  or any  organization  that shall have  succeeded to the  Advisor's
business.  In no event shall the Trust use the name "Hotchkis and Wiley Variable
Trust" or any name  including  the words  "Hotchkis  and Wiley" if the Advisor's
function is transferred or assigned to a company over which Merrill Lynch & Co.,
Inc. does not have control.

      8.    Agreement Binding Only on Trust Property

      The Advisor  understands  that the  obligations  of this Agreement are not
binding upon any shareholder of the Trust personally,  but bind only the Trust's
property;  the Advisor  represents  that it has notice of the  provisions of the
Trust's  Declaration  of Trust  disclaiming  shareholder  liability  for acts or
obligations of the Trust.

      IN  WITNESS  WHEREOF,   the  parties  hereto  have  caused  the  foregoing
instrument  to be  executed  by duly  authorized  persons  and their seals to be
hereunto affixed, all as of the day and year first above written.
