                     INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14.       Other Expenses of Issuance and Distribution

The expenses of the issuance and  distribution  of the interests in the IDS Life
Account  MGA  of  IDS  Life  Insurance  Company  to be  registered,  other  than
commissions on sales of the Contracts, are to be borne by the registrant.

Item 15.       Indemnification of Directors and Officers

The amended and restated By-Laws of the depositor provide that the depositor
will indemnify, to the fullest extent now or hereafter provided for or permitted
by law, each person involved in, or made or threatened to be made a party to,
any action, suit, claim or proceeding, whether civil or criminal, including any
investigative, administrative, legislative, or other proceeding, and including
any action by or in the right of the depositor or any other corporation, or any
partnership, joint venture, trust, employee benefit plan, or other enterprise
(any such entity, other than the depositor, being hereinafter referred to as an
"Enterprise"), and including appeals therein (any such action or process being
hereinafter referred to as a "Proceeding"), by reason of the fact that such
person, such person's testator or intestate (i) is or was a director or officer
of the depositor, or (ii) is or was serving, at the request of the depositor, as
a director, officer, or in any other capacity, or any other Enterprise, against
any and all judgments, amounts paid in settlement, and expenses, including
attorney's fees, actually and reasonably incurred as a result of or in
connection with any Proceeding, except as provided below.

No indemnification will be made to or on behalf of any such person if a judgment
or other final adjudication adverse to such person establishes that such
person's acts were committed in bad faith or were the result of active and
deliberate dishonesty and were material to the cause of action so adjudicated,
or that such person personally gained in fact a financial profit or other
advantage to which such person was not legally entitled. In addition, no
indemnification will be made with respect to any Proceeding initiated by any
such person against the depositor, or a director or officer of the depositor,
other than to enforce the terms of this indemnification provision, unless such
Proceeding was authorized by the Board of Directors of the depositor. Further,
no indemnification will be made with respect to any settlement or compromise of
any Proceeding unless and until the depositor has consented to such settlement
or compromise.

The depositor may, from time to time, with the approval of the Board of
Directors, and to the extent authorized, grant rights to indemnification, and to
the advancement of expenses, to any employee or agent of the depositor or to any
person serving at the request of the depositor as a director or officer, or in
any other capacity, of any other Enterprise, to the fullest extent of the
provisions with respect to the indemnification and advancement of expenses of
directors and officers of the depositor.

Insofar as indemnification for liability arising under the Securities Act of
1933 (the "Act") may be permitted to directors, officers and controlling persons
of the depositor or the registrant pursuant to the foregoing provisions, or
otherwise, the registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

Item 17.       Undertakings

A.     The Registrant undertakes:

         (1)      to file,  during any period in which offers or sales are being
                  made,  a   post-effective   amendment  to  this   Registration
                  Statement:

                  (i)      to  include  any   prospectus   required  by  Section
                           10(a)(3) of the Securities Act of 1933,

                  (ii)     to  reflect  in the  prospectus  any  facts or events
                           arising after the effective date of the  Registration
                           Statement   (or  the   most   recent   post-effective
                           amendment  thereof)  which,  individually  or in  the
                           aggregate,  represent  a  fundamental  change  in the
                           information set forth in the Registration Statement,

                  (iii)    to include any material  information  with respect to
                           the plan of distribution not previously  disclosed in
                           the Registration  Statement or any material change to
                           such information in the Registration Statement,

         (2)      that, for the purpose of determining  any liability  under the
                  Securities  Act of 1933,  each such  post-effective  amendment
                  shall be deemed to be a new Registration Statement relating to
                  the  securities  offered  therein,  and the  offering  of such
                  securities  at that time may be deemed to be the initial  bona
                  fide offering thereof,

         (3)      that  all  post-effective  amendments  will  comply  with  the
                  applicable  forms,  rules and regulations of the Commission in
                  effect at the time such  post-effective  amendments are filed,
                  and

         (4)      to  remove  from  registration  by means  of a  post-effective
                  amendment any of the securities  being registered which remain
                  unsold at the termination of the offering.

B.       The  Registrant  represents  that  it is  relying  upon  the  no-action
         assurance given to the American Council of Life Insurance (pub.  avail.
         Nov. 28, 1988). Further, the Registrant represents that it has complied
         with the provisions of paragraphs (1) - (4) of the no-action letter.
