to the Accounts at net asset value;

      NOW,  THEREFORE,  in consideration of their mutual promises,  the Trust,
MFS, and the Company agree as follows:


ARTICLE I.  SALE OF TRUST SHARES

      1.1.  The Trust  agrees to sell to the Company  those  Shares  which the
      Accounts  order  (based on  orders  placed  by  Policy  holders  on that
      Business Day, as defined  below) and which are available for purchase by
      such  Accounts,  executing such orders on a daily basis at the net asset
      value next  computed  after  receipt by the Trust or its designee of the
      order for the Shares.  For  purposes of this  Section  1.1,  the Company
      shall be the  designee  of the Trust for  receipt  of such  orders  from
      Policy owners and receipt by such designee shall  constitute  receipt by
      the Trust.  In this  regard,  the Company  shall use its best efforts to
      notify the Trust of such  orders by 9:30 a.m.  New York time on the next
      following  Business Day,  provided that in any event the Company will so
      notify  the  Trust by 10:30  a.m.  New York  time on the next  following




      Business  Day.  "Business  Day" shall mean any day on which the New York
      Stock  Exchange,  Inc. (the "NYSE") is open for trading and on which the
      Trust calculates its net asset value pursuant to the rules of the SEC.

      1.2.  The Trust  agrees to make the Shares  available  indefinitely  for
      purchase at the  applicable net asset value per share by the Company and
      the Accounts on those days on which the Trust  calculates  its net asset
      value  pursuant to rules of the SEC and the Trust shall  calculate  such
      net  asset  value  on each  day  which  the  NYSE is open  for  trading.
      Notwithstanding  the foregoing,  the Board of Trustees of the Trust (the
      "Board") may refuse to sell any Shares to the Company and the  Accounts,
      or suspend or  terminate  the  offering  of the Shares if such action is
      required by law or by regulatory  authorities having jurisdiction or is,
      in the sole discretion of the Board acting in good faith and in light of
      its  fiduciary  duties  under  federal  and any  applicable  state laws,
      necessary in the best interest of the Shareholders of such Portfolio.

      1.3.  The  Trust  and MFS  agree  that the  Shares  will be sold only to
      insurance  companies  which have entered into  participation  agreements
      with the Trust and MFS (the  "Participating  Insurance  Companies")  and
      their separate accounts,  qualified pension and retirement plans and MFS
      or its  affiliates.  The Trust and MFS will not sell Trust shares to any
      insurance  company or separate  account  unless an agreement  containing
      provisions  substantially  the  same  as  Articles  III  and VII of this
      Agreement is in effect to govern such sales. The Company will not resell
      the Shares except to the Trust or its agents.

      1.4.  The Trust agrees to redeem for cash, on the Company's request, any
      full or fractional  Shares held by the Accounts  (based on orders placed
      by Policy owners on that  Business  Day),  executing  such requests on a
      daily basis at the net asset value next  computed  after  receipt by the
      Trust or its  designee of the request for  redemption.  For  purposes of
      this  Section  1.4,  the Company  shall be the designee of the Trust for
      receipt of requests  for  redemption  from Policy  owners and receipt by
      such designee shall constitute receipt by the Trust. In this regard, the
      Company  shall use its best  efforts to notify the Trust of such request
      for redemption by 9:30 a.m. New York time on the next following Business
      Day,  provided that in any event the Company will so notify the Trust by
      10:30 a.m. New York time the next following Business Day.

      1.5.  Each purchase, redemption and exchange order placed by the Company
      shall be placed  separately  for each  Portfolio and shall not be netted
      with respect to any Portfolio.  However,  with respect to payment of the
      purchase  price by the Company and of redemption  proceeds by the Trust,
      the Company and the Trust shall net purchase and redemption  orders with
      respect to each  Portfolio and shall transmit one net payment for all of
      the Portfolios in accordance with Section 1.6 hereof.




      1.6.  In the  event of net  purchases,  the  Company  shall  pay for the
      Shares by 2:00  p.m.  New York  time on the next  Business  Day after an
      order to purchase the Shares is made in accordance  with the  provisions
      of Section 1.1. hereof. In the event of net redemptions, the Trust shall
      pay the  redemption  proceeds  by 2:00  p.m.  New York  time on the next
      Business  Day after an order to redeem the shares is made in  accordance
      with the provisions of Section 1.4.  hereof.  All such payments shall be
      in federal funds transmitted by wire.

      1.7.  Issuance  and  transfer  of the Shares will be by book entry only.
      Stock  certificates  will not be issued to the Company or the  Accounts.
      The Shares  ordered  from the Trust will be recorded  in an  appropriate
      title for the Accounts or the appropriate subaccounts of the Accounts.

      1.8.  The Trust shall furnish notice to the Company (by facsimile  copy,
      followed by telephone confirmation),  on or prior to the payment date of
      any dividends or capital gain  distributions  payable on the Shares. The
      Company hereby elects to receive all such dividends and distributions as
      are  payable  on a  Portfolio's  Shares  in  additional  Shares  of that
      Portfolio. The Trust shall notify the Company of the number of Shares so
      issued as payment of such dividends and distributions.

      1.9.  The Trust or its  custodian  shall  make the net  asset  value per
      share for each  Portfolio  available to the Company on each Business Day
      as soon as reasonably  practical  after the net asset value per share is
      calculated  and shall use its best  efforts to make such net asset value
      per share  available by 6:30 p.m.  New York time.  In the event that the
      Trust is unable  to meet the 6:30  p.m.  time  stated  herein,  it shall
      provide additional time for the Company to place orders for the purchase
      and  redemption of Shares.  Such  additional  time shall be equal to the
      additional  time  which  the  Trust  takes to make the net  asset  value
      available to the Company.  If the Trust  provides  materially  incorrect
      share net asset value information, the Trust shall make an adjustment to
      the number of shares  purchased  or redeemed for the Accounts to reflect
      the  correct  net  asset  value per  share.  Any  material  error in the
      calculation  or  reporting  of net asset  value per share,  dividend  or
      capital gains  information  shall be reported promptly upon discovery to
      the Company.

      be  registered  under the 1933 Act or are exempt  from or not subject to
      registration thereunder, and that the Policies will be issued, sold, and
      distributed  in compliance in all material  respects with all applicable




      state and federal laws,  including without  limitation the 1933 Act, the

      Internal  Revenue Code of 1986,  as amended (the  "Code"),  that it will
      maintain  such  treatment  and  that it will  notify  the  Trust  or MFS
      immediately  upon  having a  reasonable  basis  for  believing  that the
      Policies  have  ceased to be so  treated  or that  they  might not be so
      treated in the future.

      2.3.  The  Company   represents  and  warrants  that  American   General

      good standing of the NASD and is registered as a broker-dealer  with the
      SEC. The Trust and MFS represent that the Trust and the Underwriter will

      with all applicable state and federal securities laws, including without
      limitation the 1933 Act, the 1934 Act, and the 1940 Act.

      2.8.  No less frequently than annually,  the Company shall submit to the
      Board such reports, material or data as the Board may reasonably request
      so that it may carry out fully the  obligations  imposed  upon it by the
      conditions contained in the exemptive  application pursuant to which the
      SEC has granted exemptive relief to permit mixed and shared funding (the
      "Mixed and Shared Funding Exemptive Order").


ARTICLE III.  PROSPECTUS AND PROXY STATEMENTS; VOTING

      3.1.  At least  annually,  the Trust or its designee  shall  provide the

      Company,  free of charge,  with as many copies of the current prospectus
      (describing  only the  Portfolios  listed in  Schedule A hereto) for the
      Shares  as the  Company  may  reasonably  request  for  distribution  to
      existing  Policy  owners whose  Policies are funded by such Shares.  The
      Trust or its  designee  shall  provide  the  Company,  at the  Company's
      expense, with as many copies of the current prospectus for the Shares as
      the  Company may  reasonably  request for  distribution  to  prospective
      purchasers of Policies. If requested by the Company in lieu thereof, the
      Trust or its  designee  shall  provide such  documentation  (including a
      "camera  ready"  copy of the new  prospectus  as set in type or,  at the
      request of the Company,  as a diskette in the form sent to the financial
      printer) and other  assistance as is  reasonably  necessary in order for
      the parties hereto once each year (or more  frequently if the prospectus
      for the Shares is  supplemented  or amended) to have the  prospectus for
      the Policies and the prospectus  for the Shares printed  together in one
      document;  the expenses of such printing to be  apportioned  between (a)
      the  Company  and (b) the Trust or its  designee  in  proportion  to the
      number of pages of the Policy and Shares'  prospectuses,  taking account




      of other  relevant  factors  affecting the expense of printing,  such as
      covers,  columns,  graphs and charts;  the Trust or its designee to bear
      the cost of printing the Shares' prospectus portion of such document for
      distribution to owners of existing Policies funded by the Shares and the
      Company to bear the  expenses of printing  the portion of such  document
      relating to the Accounts; PROVIDED, however, that the Company shall bear
      all  printing  expenses  of  such  combined  documents  where  used  for
      distribution to prospective purchasers or to owners of existing Policies
      not funded by the Shares.  In the event that the Company  requests  that
      the Trust or its designee  provides the Trust's  prospectus in a "camera
      ready" or diskette format,  the Trust shall be responsible for providing
      the  prospectus  in the  format  in  which  it or MFS is  accustomed  to
      formatting  prospectuses  and shall bear the  expense of  providing  the
      prospectus in such format (E.G.,  typesetting expenses), and the Company
      shall bear the expense of  adjusting  or changing  the format to conform
      with any of its prospectuses.

      3.2.  The  prospectus  for the Shares shall state that the  statement of
      additional information for the Shares is available from the Trust or its
      designee.  The Trust or its  designee,  at its expense,  shall print and
      provide such  statement of additional  information  to the Company (or a
      master of such  statement  suitable for  duplication by the Company) for
      distribution to any owner of a Policy funded by the Shares. The Trust or
      its  designee,  at the Company's  expense,  shall print and provide such
      statement  to the Company (or a master of such  statement  suitable  for
      duplication by the Company) for distribution to a prospective  purchaser
      who requests such statement or to an owner of a Policy not funded by the
      Shares.

      3.3.  The Trust or its designee shall provide the Company free of charge
      copies,  if and to the extent  applicable to the Shares,  of the Trust's
      proxy  materials,  reports to Shareholders and other  communications  to
      Shareholders  in such quantity as the Company shall  reasonably  require
      for distribution to Policy owners.

      3.4.  Notwithstanding  the  provisions  of Sections  3.1,  3.2,  and 3.3
      above,  or of  Article V below,  the  Company  shall pay the  expense of
      printing or providing  documents to the extent such cost is considered a
      distribution  expense.  Distribution  expenses  would  include by way of
      illustration,  but are not  limited  to,  the  printing  of the  Shares'
      prospectus or prospectuses for distribution to prospective purchasers or
      to owners of existing Policies not funded by such Shares.

      3.5.  The Trust hereby  notifies the Company that it may be  appropriate
      to  include  in the  prospectus  pursuant  to which a Policy is  offered
      disclosure regarding the potential risks of mixed and shared funding.

      3.6.  If and to the extent required by law, the Company shall:




            (a)   solicit voting instructions from Policy owners;

            (b)   vote the Shares in  accordance  with  instructions  received
                  from Policy owners; and

            (c)   vote the Shares for which no instructions have been received
                  in the same  proportion as the Shares of such  Portfolio for
                  which instructions have been received from Policy owners;

      so long as and to the extent that the SEC  continues  to  interpret  the
      1940 Act to require pass through voting privileges for variable contract
      owners.  The Company will in no way recommend  action in connection with
      or oppose or interfere with the  solicitation  of proxies for the Shares
      held for such  Policy  owners.  The Company  reserves  the right to vote
      shares held in any  segregated  asset  account in its own right,  to the
      extent  permitted by law.  Participating  Insurance  Companies  shall be
      responsible  for assuring that each of their separate  accounts  holding
      Shares  calculates voting privileges in the manner required by the Mixed
      and Shared Funding  Exemptive  Order.  The Trust and MFS will notify the
      Company of any changes of interpretations or amendments to the Mixed and
      Shared Funding Exemptive Order.


ARTICLE IV.  SALES MATERIAL AND INFORMATION

      4.1.  The Company shall furnish, or shall cause to be furnished,  to the
      Trust  or  its  designee,  each  piece  of  sales  literature  or  other
      promotional  material  in which the  Trust,  MFS,  any other  investment
      adviser to the Trust,  or any affiliate of MFS are named, at least three
      (3) Business  Days prior to its use. No such  material  shall be used if

      4.2.  The  Company   shall  not  give  any   information   or  make  any

      the Trust or any other such  entity in  connection  with the sale of the
      Policies other than the information or representations  contained in the
      registration   statement,   prospectus   or  statement   of   additional
      information for the Shares, as such registration  statement,  prospectus
      and statement of additional  information  may be amended or supplemented
      from time to time, or in reports or proxy  statements for the Trust,  or
      in sales literature or other promotional material approved by the Trust,
      MFS or their  respective  designees,  except with the  permission of the




      Trust,  MFS or  their  respective  designees.  The  Trust,  MFS or their
      respective  designees each agrees to respond to any request for approval
      on a prompt and timely  basis.  The Company  shall  adopt and  implement
      procedures reasonably designed to ensure that information concerning the
      Trust,  MFS or any of their affiliates which is intended for use only by
      brokers or agents selling the Policies  (I.E.,  information  that is not
      intended for distribution to Policy owners or prospective Policy owners)
      is so used, and neither the Trust, MFS nor any of their affiliates shall
      be liable for any losses,  damages or expenses  relating to the improper
      use of such broker only materials.

      4.3.  The Trust or its  designee  shall  furnish,  or shall  cause to be

      literature or other promotional material in which the Company and/or the
      Accounts is named, at least three (3) Business Days prior to its use. No
      such  material  shall be used if the Company or its designee  reasonably
      objects to such use within three (3) Business Days after receipt of such
      material.

      4.4.  The Trust and MFS shall not give,  and agree that the  Underwriter
      shall not give, any information or make any representations on behalf of
      the Company or concerning the Company, the Accounts,  or the Policies in
      connection  with the sale of the Policies other than the  information or
      representations  contained in a registration statement,  prospectus,  or
      statement  of  additional   information   for  the  Policies,   as  such
      registration   statement,   prospectus   and   statement  of  additional
      information  may be amended  or  supplemented  from time to time,  or in
      reports for the Accounts,  or in sales  literature or other  promotional
      material  approved  by the  Company  or its  designee,  except  with the
      permission of the Company. The Company or its designee agrees to respond
      to any request for  approval on a prompt and timely  basis.  The parties
      hereto agree that this Section 4.4. is neither intended to designate nor
      otherwise  imply  that  MFS  is an  underwriter  or  distributor  of the
      Policies.

      4.5.  The Company and the Trust (or its  designee in lieu of the Company
      or the Trust,  as  appropriate)  will each provide to the other at least
      one  complete  copy  of  all  registration   statements,   prospectuses,
      statements of additional information,  reports, proxy statements,  sales
      literature and other promotional materials, applications for exemptions,
      requests for no-action letters,  and all amendments to any of the above,
      that relate to the Policies,  or to the Trust or its Shares, prior to or
      contemporaneously with the filing of such document with the SEC or other
      regulatory  authorities.  The  Company  and the  Trust  shall  also each
      promptly  inform the other of the results of any  examination by the SEC
      (or other  regulatory  authorities)  that relates to the  Policies,  the
      Trust  or its  Shares,  and  the  party  that  was  the  subject  of the
      examination  shall  provide  the  other  party  with a copy of  relevant
      portions of any "deficiency  letter" or other  correspondence or written
      report regarding any such examination.




      4.6.  The Trust and MFS will  provide the Company with as much notice as
      is reasonably  practicable of any proxy  solicitation for any Portfolio,
      and of  any  material  change  in the  Trust's  registration  statement,
      particularly   any  change  resulting  in  change  to  the  registration
      statement or prospectus or statement of additional  information  for any
      Account.  The Trust and MFS will  cooperate  with the  Company  so as to
      enable the  Company to solicit  proxies  from  Policy  owners or to make
      changes  to its  prospectus,  statement  of  additional  information  or
      registration  statement,  in an orderly  manner.  The Trust and MFS will
      make  reasonable  efforts to attempt to have  changes  affecting  Policy
      prospectuses become effective simultaneously with the annual updates for
      such prospectuses.

      4.7.  For purpose of this Article IV and Article VIII, the phrase "sales
      literature or other promotional material" includes but is not limited to
      advertisements  (such as material  published,  or designed for use in, a
      newspaper,  magazine, or other periodical, radio, television,  telephone
      or tape  recording,  videotape  display,  signs  or  billboards,  motion
      pictures,  or  other  public  media),  and  sales  literature  (such  as

      available to customers or the public,  educational or training materials
      or communications distributed or made generally available to some or all
      agents or employees.


ARTICLE V.  FEES AND EXPENSES

      5.1.  The Trust  shall pay no fee or other  compensation  to the Company
      under  this  Agreement,  and  the  Company  shall  pay no  fee or  other
      compensation  to the Trust,  except  that if the Trust or any  Portfolio
      adopts and  implements a plan  pursuant to Rule 12b-1 under the 1940 Act
      to  finance  distribution  and  Shareholder  servicing  expenses,  then,
      subject  to  obtaining  any  required  exemptive  orders  or  regulatory
      approvals,  the  Trust  may  make  payments  to  the  Company  or to the
      underwriter for the Policies if and in amounts agreed to by the Trust in
      writing. Each party,  however,  shall, in accordance with the allocation
      of expenses  specified  in Articles  III and V hereof,  reimburse  other
      parties  for  expenses  initially  paid by one  party but  allocated  to
      another  party.  In addition,  nothing  herein shall prevent the parties
      hereto from otherwise agreeing to perform, and arranging for appropriate
      compensation  for,  other  services  relating to the Trust and/or to the
      Accounts.

      5.2.  The Trust or its designee  shall bear the expenses for the cost of

      registration  and  qualification  of the  Shares  under  all  applicable
      federal and state laws, including  preparation and filing of the Trust's
      registration  statement,  and  payment of filing  fees and  registration
      fees;  preparation and filing of the Trust's proxy materials and reports
      to  Shareholders;  setting  in type  and  printing  its  prospectus  and

      determined  in accordance  with Article III above);  setting in type and
      printing the proxy materials and reports to Shareholders  (to the extent
      provided by and as




      determined in accordance with Article III above); the preparation of all
      statements and notices required of the Trust by any federal or state law
      with respect to its Shares; all taxes on the issuance or transfer of the
      Shares; and the costs of distributing the Trust's prospectuses and proxy
      materials  to owners of Policies  funded by the Shares and any  expenses
      permitted to be paid or assumed by the Trust pursuant to a plan, if any,
      under  Rule  12b-1  under  the 1940 Act.  The  Trust  shall not bear any
      expenses of marketing the Policies.

      5.3.  The  Company  or  its   designee   shall  bear  the   expenses  of
      distributing  the Shares'  prospectus or prospectuses in connection with
      new sales of the Policies and of  distributing  the Trust's  Shareholder
      reports to Policy owners. The Company shall bear all expenses associated
      with the registration,  qualification,  and filing of the Policies under
      applicable  federal  securities  and state  insurance  laws; the cost of
      preparing, printing and distributing the Policy prospectus and statement
      of  additional  information;  and the cost of  preparing,  printing  and
      distributing  annual individual  account statements for Policy owners as
      required by state insurance laws.

      5.4   MFS  will   quarterly   reimburse  the  Company   certain  of  the
      administrative costs and expenses incurred by the Company as a result of
      operations  necessitated by the beneficial ownership by Policy owners of
      shares of the  Portfolios  of the Trust,  equal to ___% per annum of the
      net  assets of the  Trust  attributable  to  variable  life or  variable
      annuity contracts offered by the Company or its affiliates.  In no event
      shall such fee be paid by the Trust,  its  shareholders or by the Policy
      holders.


ARTICLE VI.  DIVERSIFICATION AND RELATED LIMITATIONS

      6.1.  The Trust and MFS represent and warrant that each Portfolio of the
      Trust will meet the diversification  requirements of Section 817 (h) (1)
      of the Code and Treas.  Reg.  1.817-5,  relating to the  diversification
      requirements  for  variable  annuity,   endowment,   or  life  insurance
      contracts,  as they may be  amended  from time to time (and any  revenue
      rulings, revenue procedures,  notices, and other published announcements
      of the Internal  Revenue Service  interpreting  these  sections),  as if
      those requirements applied directly to each such Portfolio.

      6.2.  In the  event of a breach  of  Section  6.1 above by the Trust and
      MFS,  the  Trust  and MFS  will  take  reasonable  steps  to  adequately
      diversify each Portfolio of the Trust so as to achieve compliance within




      the grace period afforded by Treas. Reg. 1.817-5.


ARTICLE VII.  POTENTIAL MATERIAL CONFLICTS

      7.1.  The Trust  agrees that the Board,  constituted  with a majority of
      disinterested trustees, will monitor each Portfolio of the Trust for the
      existence of any material  irreconcilable conflict between the interests
      of the variable  annuity contract owners and the variable life insurance
      policy  owners of the Company  and/or  affiliated  companies  ("contract
      owners") investing in the Trust. The Board shall have the sole authority
      to  determine if a material  irreconcilable  conflict  exists,  and such
      determination  shall be binding on the  Company  only if approved in the
      form of a  resolution  by a majority of the Board,  or a majority of the
      disinterested  trustees of the Board.  The Board will give prompt notice
      of any such determination to the Company.

      7.2.  The Company agrees that it will be  responsible  for assisting the
      Board in carrying  out its  responsibilities  under the  conditions  set
      forth in the Trust's exemptive application pursuant to which the SEC has
      granted the Mixed and Shared  Funding  Exemptive  Order by providing the
      Board, as it may reasonably request,  with all information necessary for
      the Board to  consider  any issues  raised  and  agrees  that it will be
      responsible for promptly  reporting any potential or existing  conflicts
      of which it is aware to the  Board  including,  but not  limited  to, an
      obligation by the Company to inform the Board  whenever  contract  owner
      voting instructions are disregarded.  The Company also agrees that, if a
      material  irreconcilable conflict arises, it will at its own cost remedy
      such conflict up to and including (a) withdrawing  the assets  allocable
      to some or all of the  Accounts  from  the  Trust or any  Portfolio  and
      reinvesting such assets in a different investment medium, including (but
      not limited to) another  Portfolio of the Trust, or submitting to a vote
      of all  affected  contract  owners  whether to withdraw  assets from the
      Trust or any  Portfolio  and  reinvesting  such  assets  in a  different
      investment   medium  and,  as   appropriate,   segregating   the  assets
      attributable to any  appropriate  group of contract owners that votes in
      favor of such  segregation,  or offering to any of the affected contract
      owners  the  option of  segregating  the  assets  attributable  to their
      contracts or policies,  and (b) establishing a new registered management
      investment  company and segregating the assets  underlying the Policies,
      unless a majority of Policy owners materially  adversely affected by the
      conflict  have voted to decline the offer to establish a new  registered
      management investment company.




      7.3.  A  majority  of the  disinterested  trustees  of the  Board  shall
      determine whether any proposed action by the Company adequately remedies
      any  material  irreconcilable  conflict.  In the  event  that the  Board
      determines  that any  proposed  action  does not  adequately  remedy any
      material  irreconcilable   conflict,  the  Company  will  withdraw  from
      investment  in  the  Trust  each  of  the  Accounts  designated  by  the
      disinterested  trustees  and  terminate  this  Agreement  within six (6)




      months after the Board  informs the Company in writing of the  foregoing
      determination;  PROVIDED,  HOWEVER, that such withdrawal and termination
      shall be  limited  to the extent  required  to remedy any such  material
      irreconcilable conflict as determined by a majority of the disinterested
      trustees of the Board.

      7.4.  If and to the extent that Rule 6e-2 and Rule  6e-3(T) are amended,
      or Rule 6e-3 is adopted,  to provide exemptive relief from any provision
      of the 1940 Act or the rules  promulgated  thereunder  with  respect  to
      mixed or shared  funding  (as  defined in the Mixed and  Shared  Funding
      Exemptive Order) on terms and conditions materially different from those
      contained in the Mixed and Shared Funding  Exemptive Order, then (a) the
      Trust and/or the  Participating  Insurance  Companies,  as  appropriate,
      shall take such steps as may be  necessary  to comply with Rule 6e-2 and
      6e-3(T), as amended, and Rule 6e-3, as adopted, to the extent such rules
      are applicable; and (b) Sections 3.5, 3.6, 7.1, 7.2, 7.3 and 7.4 of this
      Agreement  shall  continue  in effect  only to the extent that terms and
      conditions  substantially  identical to such  Sections are  contained in
      such Rule(s) as so amended or adopted.

      variable life insurance  contracts  (with respect to which any Portfolio
      serves as an underlying funding vehicle) as life insurance, endowment or
      annuity contracts under applicable provisions of the Code.




      8.4.  Neither  the  Company  nor the  Trust  shall be  liable  under the
            indemnification   provisions  contained  in  this  Agreement  with
            respect to any losses, claims, damages, liabilities or expenses to
            which an Indemnified Party would otherwise be subject by reason of
            such Indemnified Party's willful misfeasance,  willful misconduct,
            or gross negligence in the performance of such Indemnified Party's
            duties or by reason of such Indemnified Party's reckless disregard
            of obligations and duties under this Agreement.

      8.5.  Promptly after receipt by an Indemnified  Party under this Section
            8.5. of notice of  commencement  of any action,  such  Indemnified
            Party will,  if a claim in respect  thereof is to be made  against
            the indemnifying party under this section, notify the indemnifying
            party of the commencement  thereof;  but the omission so to notify
            the  indemnifying  party will not  relieve  it from any  liability
            which it may have to any  Indemnified  Party  otherwise than under
            this  section.  In case any such  action is  brought  against  any
            Indemnified  Party, and it notified the indemnifying  party of the
            commencement  thereof,  the indemnifying party will be entitled to
            participate  therein  and, to the extent that it may wish,  assume
            the defense thereof, with counsel satisfactory to such Indemnified
            Party.  After notice from the indemnifying  party of its intention
            to assume the defense of an action,  the  Indemnified  Party shall
            bear the expenses of any  additional  counsel  obtained by it, and
            the  indemnifying  party  shall not be liable to such  Indemnified
            Party  under  this  section  for  any  legal  or  other   expenses
            subsequently incurred by such Indemnified Party in connection with
            the defense thereof other than reasonable costs of investigation.

      8.6.  Each of the parties agrees promptly to notify the other parties of
            the commencement of any litigation or proceeding against it or any
            of its respective officers, directors, trustees, employees or 1933
            Act control persons in connection with the Agreement, the issuance
            or sale of the Policies,  the  operation of the  Accounts,  or the
            sale or acquisition of Shares.

      8.7.  A  successor  by law of the  parties  to this  Agreement  shall be
            entitled to the benefits of the indemnification  contained in this
            Article VIII.  The  indemnification  provisions  contained in this
            Article VIII shall survive any termination of this Agreement.


ARTICLE IX.  APPLICABLE LAW

      9.1.  This  Agreement  shall  be  construed  and the  provisions  hereof
            interpreted   under  and  in  accordance  with  the  laws  of  The
            Commonwealth of Massachusetts.

      9.2.  This  Agreement  shall be subject to the  provisions  of the 1933,
            1934 and 1940  Acts,  and the rules and  regulations  and  rulings
            thereunder,  including such exemptions from those statutes,  rules






            and regulations as the SEC may grant and the terms hereof shall be
            interpreted and construed in accordance therewith.

ARTICLE X.  NOTICE OF FORMAL PROCEEDINGS

      The  Trust,  MFS,  and the  Company  agree  that each such  party  shall
promptly  notify  the other  parties to this  Agreement,  in  writing,  of the
institution  of any  formal  proceedings  brought  against  such  party or its
designees  by the NASD,  the SEC,  or any  insurance  department  or any other
regulatory  body regarding such party's duties under this Agreement or related
to the sale of the Policies, the operation of the Accounts, or the purchase of
the Shares.


ARTICLE XI.  TERMINATION

      11.1. This Agreement  shall  terminate with respect to the Accounts,  or
            one, some, or all Portfolios:

            (a)   at the option of any party upon twelve (12) months'  advance
                  written notice to the other parties; or

            (b)   at the option of the  Company to the extent  that the Shares
                  of  Portfolios  are not  reasonably  available  to meet  the
                  requirements of the Policies or are not "appropriate funding
                  vehicles" for the Policies,  as reasonably determined by the
                  Company.  Without  limiting the generality of the foregoing,
                  the Shares of a Portfolio would not be "appropriate  funding
                  vehicles"  if,  for  example,  such  Shares did not meet the
                  diversification or other requirements referred to in Article
                  VI hereof; or if the Company would be permitted to disregard
                  Policy  owner voting  instructions  pursuant to Rule 6e-2 or
                  6e-3(T) under the 1940 Act. Prompt notice of the election to
                  terminate  for such cause and an  explanation  of such cause
                  shall be furnished to the Trust by the Company; or

            (c)   at the option of the Trust or MFS upon institution of formal
                  proceedings   against  the   Company  or  American   General
                  Securities  Incorporated  by  the  NASD,  the  SEC,  or  any
                  insurance  department or any other regulatory body regarding
                  the Company's  duties under this Agreement or related to the
                  sale of the Policies,  the operation of the Accounts, or the
                  purchase of the Shares; or

            (d)   at the  option of the  Company  upon  institution  of formal
                  proceedings  against  the  Trust or the  Underwriter  by the
                  NASD,  the  SEC,  or  any  state   securities  or  insurance




                  department  or  any  other  regulatory  body  regarding  the
                  Trust's or MFS' duties  under this  Agreement  or related to
                  the sale of the Shares; or

            (e)   at the option of the Company,  the Trust or MFS upon receipt
                  of any necessary regulatory approvals and/or the vote of the
                  Policy  owners  having an interest in the  Accounts  (or any
                  subaccounts) to substitute the shares of another  investment
                  company for the corresponding Portfolio Shares in accordance
                  with the terms of the  Policies  for which  those  Portfolio
                  Shares  had  been  selected  to  serve  as  the   underlying
                  investment  media.  The Company  will give thirty (30) days'
                  prior  written  notice  to  the  Trust  of the  Date  of any
                  proposed  vote or other  action taken to replace the Shares;
                  or

            (f)   termination  by either the Trust or MFS by written notice to
                  the  Company,  if  either  one or both of the  Trust  or MFS
                  respectively,   shall  determine,  in  their  sole  judgment
                  exercised  in good faith,  that the  Company has  suffered a
                  material   adverse  change  in  its  business,   operations,
                  financial  condition,  or  prospects  since the date of this
                  Agreement or is the subject of material  adverse  publicity;
                  or

            (g)   termination  by the  Company by written  notice to the Trust
                  and  MFS,  if the  Company  shall  determine,  in  its  sole
                  judgment  exercised in good faith, that the Trust or MFS has
                  suffered  a  material   adverse  change  in  this  business,
                  operations,  financial condition or prospects since the date
                  of this  Agreement  or is the  subject of  material  adverse
                  publicity; or

            (h)   at the option of any party to this  Agreement,  upon another
                  party's  material breach of any provision of this Agreement;
                  or

            (i)   upon  assignment  of this  Agreement,  unless  made with the
                  written consent of the parties hereto.

      11.2. The notice shall  specify the  Portfolio or  Portfolios,  Policies
            and, if  applicable,  the Accounts as to which the Agreement is to
            be terminated.

      11.3. It is understood  and agreed that the right of any party hereto to
            terminate  this  Agreement  pursuant  to  Section  11.1(a)  may be
            exercised for cause or for no cause.

      11.4. Except  as   necessary  to   implement   Policy  owner   initiated
            transactions,   or  as  required  by  state   insurance   laws  or
            regulations,  the Company shall not redeem the Shares attributable
            to the  Policies  (as  opposed to the Shares  attributable  to the
            Company's assets held in the Accounts),  and the Company shall not




            prevent Policy owners from allocating payments to a Portfolio that
            was otherwise available under the Policies, until thirty (30) days
            after the Company  shall have  notified the Trust of its intention
            to do so.

      11.5. Notwithstanding  any termination of this Agreement,  the Trust and
            MFS  shall,  at  the  option  of the  Company,  continue  to  make
            available  additional  shares of the  Portfolios  pursuant  to the
            terms and conditions of this Agreement, for all Policies in effect
            on the  effective  date  of  termination  of this  Agreement  (the
            "Existing  Policies"),  except as otherwise provided under Article
            VII of  this  Agreement.  Specifically,  without  limitation,  the
            owners of the Existing  Policies shall be permitted to transfer or
            reallocate  investment under the Policies,  redeem  investments in
            any  Portfolio  and/or  invest  in the  Trust  upon the  making of
            additional purchase payments under the Existing Policies.

            reasonably  identified  as  confidential  in  writing by any other
            party  hereto and,  except as  permitted  by this  Agreement or as
            otherwise  required by  applicable  law or  regulation,  shall not

            of the  affected  party  until  such  time as it may come into the
