as an open-end, diversified management investment company; and
 
  WHEREAS, TRUST is comprised of several series funds (each a "Portfolio"), with
those Portfolios currently available being listed on Appendix A hereto; and

  WHEREAS, TRUST may also offer its shares to certain qualified pension and
retirement plans ("Qualified Plans"); and
 
  WHEREAS, TRUST has received an order from the SEC, granting Participating
Insurance Companies and their separate accounts exemptions from the provisions
of Sections 9(a), 13(a), 15(a) and 15(b) of the '40 Act, and Rules 6e-2(b)(15)
and 6e-3(T)(b)(15) thereunder, to the extent necessary to permit shares of the
Portfolios of the TRUST to be sold to and held by Variable Contract Separate
Accounts of both affiliated and unaffiliated Participating Insurance Companies
and Qualified Plans ("Exemptive Order"); and
 
  WHEREAS, LIFE COMPANY has established or will establish one or more Separate

                                       1

 
  NOW, THEREFORE, in consideration of their mutual promises, LIFE COMPANY,
TRUST, and ADVISER agree as follows:


                        Article I.  SALE OF TRUST SHARES

     1.1  TRUST agrees to make available to the Separate Accounts of LIFE
COMPANY the selected Portfolios as listed on Appendix B for investment of
purchase payments of Variable Contracts allocated to the designated Separate
Accounts as provided in TRUST's Registration Statement.

     1.2  TRUST agrees to sell to LIFE COMPANY those shares of the selected
Portfolios of TRUST which LIFE COMPANY orders, executing such orders on a daily
basis at the net asset value next computed after receipt by TRUST or its
designee of the order for the shares of TRUST.  For purposes of this Section
1.2, LIFE COMPANY shall be the designee of TRUST for receipt of such orders from
the designated Separate Account and receipt by such designee shall constitute
receipt by TRUST; provided that LIFE COMPANY receives the order by 4:00 p.m. New
York time and TRUST receives notice from LIFE COMPANY by telephone or facsimile
(or by such other means as TRUST and LIFE COMPANY may agree in writing) of such
order by 10:30 a.m. New York time on the next  Business Day.  "Business Day"
shall mean any day on which the New York Stock Exchange is open for trading and
on which TRUST calculates its net asset value pursuant to the rules of the SEC.

     1.3  TRUST agrees to redeem on LIFE COMPANY's request, any full or
fractional shares of TRUST held by LIFE COMPANY, executing such requests on a
daily basis at the net asset value next computed after receipt by TRUST or its
designee of the request for redemption, in accordance with the provisions of
this Agreement and TRUST's Registration Statement.  (In the event of a conflict
between the provisions of this Agreement and the Trust's Registration Statement,
the provisions of the Registration Statement shall govern.)  For purposes of
this Section 1.3, LIFE COMPANY shall be the designee of TRUST for receipt of
requests for redemption from the designated Separate Account and receipt by such
designee shall constitute receipt by TRUST; provided that LIFE COMPANY receives
the request for redemption by 4:00 p.m. New York time and TRUST receives notice
from LIFE COMPANY by telephone or facsimile (or by such other means as TRUST and
LIFE COMPANY may agree in writing) of such request for redemption by 10:30 a.m.
New York time on the next Business Day.

     1.4  TRUST shall furnish, on or before each ex-dividend date, notice to
LIFE COMPANY of any income dividends or capital gain distributions payable on
the shares of any Portfolio of TRUST. LIFE COMPANY hereby elects to receive all
such income dividends and capital gain distributions as are payable on a
Portfolio's shares in additional shares of the Portfolio. TRUST shall notify
LIFE COMPANY or its designee of the number of shares so issued as payment of
such dividends and distributions.  LIFE COMPANY reserves the right, on its
behalf and on behalf of the Separate Accounts to revoke this election and
receive all such dividends in cash.

                                       2

 
     1.5  TRUST shall make the net asset value per share for the selected
Portfolio(s) available to LIFE COMPANY on a daily basis as soon as reasonably
practicable after the net asset value per share is calculated but shall use its
best efforts to make such net asset value available by 6:30 p.m. New York time.
If TRUST provides LIFE COMPANY with materially incorrect share net asset value
information through no fault of LIFE COMPANY, LIFE COMPANY on behalf of the
Separate Accounts, shall be entitled to an adjustment to the number of shares
purchased or redeemed to reflect the correct share net asset value.  Any
material error in the calculation of net asset value per share, dividend or
capital gain information shall be reported promptly upon discovery to LIFE
COMPANY.

     1.6  At the end of each Business Day, LIFE COMPANY shall use the
information described in Section 1.5 to calculate Separate Account unit values
for the day.  Using these unit values, LIFE COMPANY shall process each such
Business Day's Separate Account transactions based on requests and premiums
received by it by the close of trading on the floor of the New York Stock
Exchange (currently 4:00 p.m. New York time) to determine the net dollar amount
of TRUST shares which shall be purchased or redeemed at that day's closing net
asset value per share.  The net purchase or redemption orders so determined
shall be transmitted to TRUST by LIFE COMPANY by 10:30 a.m. New York Time on the
Business Day next following LIFE COMPANY's receipt of such requests and premiums
in accordance with the terms of Sections 1.2 and 1.3 hereof.

     1.7  If LIFE COMPANY's order requests the purchase of TRUST shares, LIFE
COMPANY shall pay for such purchase by wiring federal funds to TRUST or its
designated custodial account on the day the order is transmitted by LIFE
COMPANY.  If LIFE COMPANY's order requests a net redemption resulting in a
payment of redemption proceeds to LIFE COMPANY, TRUST shall use its best efforts
to wire the redemption proceeds to LIFE COMPANY by the next Business Day, unless
doing so would require TRUST to dispose of Portfolio securities or otherwise
incur additional costs.  In any event, proceeds shall be wired to LIFE COMPANY
within the time  period permitted by the '40 Act or the rules, orders or
regulations thereunder, and TRUST shall notify the person designated in writing
by LIFE COMPANY as the recipient for such notice of such delay by 3:00 p.m. New
York Time on the same Business Day that LIFE COMPANY transmits the redemption
order to TRUST.  If LIFE COMPANY's order requests the application of redemption
proceeds from the redemption of shares to the purchase of shares of another Fund
advised by ADVISER, TRUST shall so apply such proceeds on the same Business Day
that LIFE COMPANY transmits such order to TRUST.

     1.8  TRUST agrees that all shares of the Portfolios of TRUST will be sold
only to Participating Insurance Companies which have agreed to participate in
TRUST to fund their Separate Accounts and/or to Qualified Plans, all in
accordance with the requirements of Section 817(h)(4) of the Internal Revenue
Code of 1986, as amended ("Code") and Treasury Regulation 1.817-5. Shares of the
TRUST's Portfolios will not be sold directly to the general public.

     1.9  TRUST may refuse to sell shares of any Portfolio to any person, or
suspend or terminate the offering of the shares of or liquidate any Portfolio of
TRUST if such action is required by law or by regulatory authorities having
jurisdiction or is, in the sole discretion of the Board of Trustees of the TRUST
(the "Board"), acting in good faith and in light of its duties under federal and
any applicable state laws, deemed necessary, desirable or appropriate and in the
best interests of the shareholders of such Portfolios.

                                       3

 
     1.10  Issuance and transfer of Portfolio shares will be by book entry only.
Stock certificates will not be issued to LIFE COMPANY or the Separate Accounts.
Shares ordered from Portfolio will be recorded in appropriate book entry titles
for the Separate Accounts.

     2.1  LIFE COMPANY represents and warrants that it is an insurance company
duly organized and in good standing under the laws of the State of Texas, and
that it has legally and validly established each Separate Account as a

registered as a broker-dealer under the Securities Exchange Act of 1934 (the
"'34 Act").

     2.2  LIFE COMPANY represents and warrants that it has registered or, prior
to any issuance or sale of the Variable Contracts, will register each Separate
Account as a unit investment trust ("UIT") in accordance with the provisions of
the '40 Act and cause each Separate Account to remain so registered to serve as
a segregated asset account for the Variable Contracts, unless an exemption from
registration is available.
 
     2.3  LIFE COMPANY represents and warrants that the Variable Contracts will
be registered under the Securities Act of 1933 (the "'33 Act") unless an
exemption from registration is available prior to any issuance or sale of the
Variable Contracts, and that the Variable Contracts will be issued and sold in
compliance in all material respects with all applicable federal and state laws
(including all applicable blue sky laws) and further that the sale of the
Variable Contracts shall comply in all material respects with applicable state
insurance law suitability requirements.
 
     2.4  LIFE COMPANY represents and warrants that the Variable Contracts are
currently and at the time of issuance will be treated as life insurance,
endowment or annuity contracts under applicable provisions of the Code, that it
will maintain such treatment and that it will notify TRUST immediately upon
having a reasonable basis for believing that the Variable Contracts have ceased
to be so treated or that they might not be so treated in the future.
 
     2.5  TRUST represents and warrants that the Trust shares offered and sold
pursuant to this Agreement will be registered under the '33 Act and sold in
accordance with all applicable federal laws, and TRUST shall be registered under

under the '33 Act and the '40 Act from time to time as required in order to

and to the extent deemed advisable by TRUST.
 
     2.6  TRUST represents and warrants that each Portfolio will comply with the
diversification requirements set forth in Section 817(h) of the Code, and the
rules and regulations thereunder, including without limitation Treasury

                                       4

 
     2.7  TRUST represents and warrants that each Portfolio invested in by the
Separate Account will be treated as a "regulated investment company" under
Subchapter M of the Code, and will notify LIFE COMPANY immediately upon having a
reasonable basis for believing it has ceased to so qualify or might not so
qualify in the future.
 
     2.8  ADVISER represents and warrants that it shall perform its obligations
hereunder in compliance in all material respects with any applicable state and
federal laws.
 

                 Article III.  PROSPECTUS AND PROXY STATEMENTS
                                        
     3.1  TRUST shall prepare and be responsible for filing with the SEC and any
state regulators requiring such filing all shareholder reports, notices, proxy
materials (or similar materials such as voting instruction solicitation
materials), prospectuses and statements of additional information of TRUST.
TRUST shall bear the costs of registration and qualification of shares of the
Portfolios, preparation and filing of the documents listed in this Section 3.1
and all taxes and filing fees to which an issuer is subject on the issuance and
transfer of its shares.
 
     3.2  TRUST or its designee shall provide LIFE COMPANY, free of charge, with
as many copies of the current prospectus (or prospectuses), statements of
additional information, annual and semi-annual reports and proxy statements for
the shares of the Portfolios as LIFE COMPANY may reasonably request for
distribution to existing Variable Contract owners whose Variable Contracts are
funded by such shares. TRUST or its designee shall provide LIFE COMPANY, at LIFE
COMPANY's expense, with as many copies of the current prospectus (or
prospectuses) for the shares as LIFE COMPANY may reasonably request for
distribution to prospective purchasers of Variable Contracts. If requested by
LIFE COMPANY, TRUST or its designee shall provide such documentation (including
a "camera ready" copy of the current prospectus (or prospectuses) as set in type
or, at the request of LIFE 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 a year (or more frequently if the prospectus (or
prospectuses) for the shares is supplemented or amended) to have the prospectus
for the Variable Contracts and the prospectus (or prospectuses) for the TRUST
shares printed together in one document. The expenses of such printing will be
apportioned between LIFE COMPANY and TRUST in proportion to the number of pages
of the Variable Contract and TRUST prospectus, taking account of other relevant
factors affecting the expense of printing, such as covers, columns, graphs and
charts; TRUST shall bear the cost of printing the TRUST prospectus portion of
such document for distribution only to owners of existing Variable Contracts
funded by the TRUST shares and LIFE COMPANY shall bear the expense of printing
the portion of such documents relating to the Separate Account; provided,
however, LIFE COMPANY shall bear all printing expenses of such combined
documents where used for distribution to prospective purchasers or to owners of
existing Variable Contracts not funded by the shares. In the event that LIFE
COMPANY requests that TRUST or its designee provide TRUST's prospectus in a
"camera ready" or diskette format, TRUST shall be responsible for providing the
prospectus (or prospectuses) in the format in which it is accustomed to
formatting prospectuses and shall bear the expense of providing the prospectus
(or prospectuses) in such format (e.g. typesetting expenses), and LIFE COMPANY
shall bear the expense of adjusting or changing the format to conform with any
of its prospectuses.

                                       5

 
     3.3  TRUST will provide LIFE COMPANY with at least one complete copy of all
prospectuses, statements of additional information, annual and semi-annual
reports, proxy statements, exemptive applications and all amendments or
supplements to any of the above that relate to the Portfolios promptly after the
filing of each such document with the SEC or other regulatory authority.  LIFE
COMPANY will provide TRUST with at least one complete copy of all prospectuses,
statements of additional information, annual and semi-annual reports, proxy
statements, exemptive applications and all amendments or supplements to any of
the above that relate to a Separate Account promptly after the filing of each
such document with the SEC or other regulatory authority.


                          Article IV.  SALES MATERIALS

     4.1  LIFE COMPANY will furnish, or will cause to be furnished, to TRUST and
ADVISER, each piece of sales literature or other promotional material in which
TRUST or ADVISER is named, at least fifteen (15) Business Days prior to its
intended use.  No such material will be used if TRUST or ADVISER objects to its
use in writing within ten (10) Business Days after receipt of such material.
 
     4.2  TRUST and ADVISER will furnish, or will cause to be furnished, to LIFE
COMPANY, each piece of sales literature or other promotional material in which
LIFE COMPANY or its Separate Accounts are named, at least fifteen (15) Business
Days prior to its intended use.  No such material will be used if LIFE COMPANY
objects to its use in writing within ten (10) Business Days after receipt of
such material.
 
     4.3  TRUST and its affiliates and agents shall not give any information or
make any representations on behalf of LIFE COMPANY or concerning LIFE COMPANY,
the Separate Accounts, or the Variable Contracts issued by LIFE COMPANY, other
than the information or representations contained in a registration statement or
prospectus for such Variable Contracts, as such registration statement and
prospectus may be amended or supplemented from time to time, or in reports of
the Separate Accounts or reports prepared for distribution to owners of such
Variable Contracts, or in sales literature or other promotional material
approved by LIFE COMPANY or its designee, except with the written permission of
LIFE COMPANY.
 
     4.4  LIFE COMPANY and its affiliates and agents shall not give any
information or make any representations on behalf of TRUST or concerning TRUST
other than the information or representations contained in a registration
statement or prospectus for TRUST, as such registration statement and prospectus
may be amended or supplemented from time to time, or in sales literature or
other promotional material approved by TRUST or its designee, except with the
written permission of TRUST.
 
     4.5  For purposes of this Agreement, the phrase "sales literature or other
promotional material" or words of similar import include, without limitation,
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),
sales literature (such as any written communication distributed or made
generally available to customers or the public, including brochures, circulars,
research reports, market letters, form 

                                       6

 
letters, seminar texts, or reprints or excerpts of any other advertisement,
sales literature, or published article), educational or training materials or
other communications distributed or made generally available to some or all
agents or employees, registration statements, prospectuses, statements of
additional information, shareholder reports and proxy materials, and any other
material constituting sales literature or advertising under National Association
of Securities Dealers, Inc. ("NASD") rules, the '40 Act, the '33 Act or rules
thereunder.
 

                        Article V.  POTENTIAL CONFLICTS
                                        
     5.1  The parties acknowledge that TRUST has received an order from the SEC
granting relief from various provisions of the '40 Act and the rules thereunder
to the extent necessary to permit TRUST shares to be sold to and held by
Variable Contract separate accounts of both affiliated and unaffiliated
Participating Insurance Companies and Qualified Plans.  The Exemptive Order
requires TRUST and each Participating Insurance Company to comply with
conditions and undertakings substantially as provided in this Section 5.  The
TRUST will not enter into a participation agreement with any other Participating
Insurance Company unless it imposes the same conditions and undertakings as are
imposed on LIFE COMPANY hereby.
 
     5.2  The Board will monitor TRUST for the existence of any material
irreconcilable conflict between the interests of Variable Contract owners of all
separate accounts and with participants of Qualified Plans  investing in TRUST.
An irreconcilable material conflict may arise for a variety of reasons, which
may include: (a) an action by any state insurance regulatory authority; (b) a
change in applicable federal or state insurance, tax, or securities laws or
regulations, or a public ruling, private letter ruling or any similar action by
insurance, tax or securities regulatory authorities; (c) an administrative or
judicial decision in any relevant proceeding; (d) the manner in which the
investments of TRUST are being managed; (e) a difference in voting instructions
given by Variable Contract owners; (f) a decision by a Participating Insurance
Company to disregard the voting instructions of Variable Contract owners and (g)
if applicable, a decision by a Qualified Plan to disregard the voting
instructions of plan participants.
 
     5.3  LIFE COMPANY will report any potential or existing conflicts of which
it becomes aware to the Board.  LIFE COMPANY will be responsible for assisting
the Board in carrying out its duties in this regard by providing the Board with
all information reasonably necessary for the Board to consider any issues
raised.  The responsibility includes, but is not limited to, an obligation by
the LIFE COMPANY to inform the Board whenever it has determined to disregard
Variable Contract owner voting instructions.  These responsibilities of LIFE
COMPANY  will be carried out with a view only to the interests of the Variable
Contract owners.

     5.4  If a majority of the Board or majority of its disinterested Trustees,
determines that a material irreconcilable conflict exists affecting LIFE
COMPANY, LIFE COMPANY, at its expense and to the extent reasonably practicable
(as determined by a majority of the Board's disinterested Trustees), will take
any steps necessary to remedy or eliminate the irreconcilable material conflict,
including; (a) withdrawing the assets allocable to some or all of the Separate
Accounts from TRUST or any Portfolio thereof and reinvesting those assets in a
different investment medium, which may 

                                       7

 
include another Portfolio of TRUST, or another investment company; (b)
submitting the question as to whether such segregation should be implemented to
a vote of all affected Variable Contract owners and as appropriate, segregating
the assets of any appropriate group (i.e., variable annuity or variable life
insurance Contract owners of one or more Participating Insurance Companies) that
votes in favor of such segregation, or offering to the affected Variable
Contract owners the option of making such a change; and (c) establishing a new
registered management investment company (or series thereof) or managed separate
account. If a material irreconcilable conflict arises because of LIFE COMPANY's
decision to disregard Variable Contract owner voting instructions, and that
decision represents a minority position or would preclude a majority vote, LIFE
COMPANY may be required, at the election of TRUST, to withdraw the Separate
Account's investment in TRUST, and no charge or penalty will be imposed as a
result of such withdrawal. The responsibility to take such remedial action shall
be carried out with a view only to the interests of the Variable Contract
owners.
 
     For the purposes of this Section 5.4, a majority of the disinterested
members of the Board shall determine whether or not any proposed action
adequately remedies any irreconcilable material conflict, but in no event will
TRUST or ADVISER (or any other investment adviser of TRUST) be required to
establish a new funding medium for any Variable Contract.  Further, LIFE COMPANY
shall not be required by this Section 5.4 to establish a new funding medium for
any Variable Contracts if any offer to do so has been declined by a vote of a
majority of Variable Contract owners materially and adversely affected by the
irreconcilable material conflict.
 
     5.5  The Board's determination of the existence of an irreconcilable
material conflict and its implications shall be made known promptly and in
writing to LIFE COMPANY.
 
     5.6  No less than annually, LIFE COMPANY shall submit to the Board such
reports, materials or data as the Board may reasonably request so that the Board
may fully carry out its obligations.  Such reports, materials, and data shall be
submitted more frequently if deemed appropriate by the Board.
 
                                 Article VI.  VOTING
 
     6.1  LIFE COMPANY will provide pass-through voting privileges to all
Variable Contract owners so long as the SEC continues to interpret the '40 Act
as requiring pass-through voting privileges for Variable Contract owners.
Accordingly, LIFE COMPANY, where applicable, will vote shares of the Portfolio
held in its Separate Accounts in a manner consistent with voting instructions
timely received from its Variable Contract owners.  LIFE COMPANY will be
responsible for assuring that each of its Separate Accounts that participates in
TRUST calculates voting privileges in a manner consistent with other
Participating Insurance Companies. LIFE COMPANY will vote shares for which it
has not received timely voting instructions, as well as shares it owns, in the
same proportion as its votes those shares for which it has received voting
instructions.

     6.2  If and to the extent Rule 6e-2 and Rule 6e-3(T) are amended, or if
Rule 6e-3 is adopted, to provide exemptive relief from any provision of the '40
Act or the rules thereunder with respect to mixed and shared funding on terms
and conditions materially different from any exemptions granted in the Exemptive
Order, then TRUST,  and/or the Participating Insurance Companies, as
appropriate, 

                                       8

 
shall take such steps as may be necessary to comply with Rule 6e-2 and Rule 
6e-3(T), as amended, and Rule 6e-3, as adopted, to the extent such Rules are
applicable.

 
                         Article VII.  INDEMNIFICATION

     7.1  Indemnification by LIFE COMPANY.  LIFE COMPANY agrees to indemnify and
hold harmless TRUST, ADVISER and each of their Trustees, directors, principals,
officers, employees and agents and each person, if any, who controls TRUST or
ADVISER within the meaning of Section 15 of the '33 Act (collectively, the
"Indemnified Parties") against any and all losses, claims, damages, liabilities
(including amounts paid in settlement with the written consent of LIFE COMPANY,
which consent shall not be unreasonably withheld) or litigation or threatened
litigation (including legal and other expenses), to which the Indemnified
Parties may become subject under any statute, regulation, at common law or
otherwise, insofar as such losses, claims, damages, liabilities or expenses (or
actions in respect thereof) or settlements are related to the sale or
acquisition of TRUST's shares or the Variable Contracts and:

     (a)  arise out of or are based upon any untrue statements or alleged untrue
  statements of any material fact contained in the Registration Statement or
  prospectus for the Variable Contracts or contained in the Variable Contracts
  (or any amendment or supplement to any of the foregoing), or arise out of or
  are based upon the omission or the alleged omission to state therein a
  material fact required to be stated therein or necessary to make the
  statements therein not misleading, provided that this agreement to indemnify
  shall not apply as to any Indemnified Party if such statement or omission or
  such alleged statement or omission was made in reliance upon and in conformity
  with information furnished in writing to LIFE COMPANY by or on behalf of TRUST
  for use in the registration statement or prospectus for the Variable Contracts
  or in the Variable Contracts or sales literature (or any amendment or
  supplement) or otherwise for use in connection with the sale of the Variable
  Contracts or TRUST shares; or

     (b)  arise out of or result from (i) statements or representations (other
  than statements or representations contained in the registration statement,
  prospectus or sales literature of TRUST not supplied by LIFE COMPANY, or
  persons under its control) or (ii)  wrongful conduct of LIFE COMPANY or
  persons under its control, with respect to the sale or distribution of the
  Variable Contracts or TRUST shares; or

     (c) arise out of any untrue statement or alleged untrue statement of a
  material fact contained in a registration statement, prospectus, or sales
  literature of TRUST or any amendment thereof or supplement thereto or the
  omission or alleged omission to state therein a material fact required to be
  stated therein or necessary to make the statements therein not misleading if
  such statement or omission or such alleged statement or omission was made in
  reliance upon and in conformity with information furnished in writing to TRUST
  by or on behalf of LIFE COMPANY; or

     (d) arise as a result of any failure by LIFE COMPANY to provide
  substantially the services and furnish the materials under the terms of this
  Agreement; or

                                       9

 
     (e) arise out of or result from any material breach of any representation
  and/or warranty made by LIFE COMPANY in this Agreement or arise out of or
  result from any other material breach of this Agreement by LIFE COMPANY.

     7.2  LIFE COMPANY shall not be liable under this indemnification provision
with respect to any losses, claims, damages, liabilities or litigation incurred
or assessed against an Indemnified Party to the extent that such losses, claims,
damages, liabilities or litigation are attributable to such Indemnified Party's
willful misfeasance, bad faith, or gross negligence in the performance of such
Indemnified Party's duties or by reason of such Indemnified Party's reckless
disregard of obligations or duties under this Agreement.
 
     7.3  LIFE COMPANY shall not be liable under this indemnification provision
with respect to any claim made against an Indemnified Party unless such
Indemnified Party shall have notified LIFE COMPANY in writing within a
reasonable time after the summons or other first legal process giving
information of the nature of the claim shall have been served upon such
Indemnified Party (or after such Indemnified Party shall have received notice of
such service on any designated agent), but failure to notify LIFE COMPANY of any
such claim shall not relieve LIFE COMPANY from any liability which it may have
to the Indemnified Party against whom such action is brought otherwise than on
account of this indemnification provision.  In case any such action is brought
against an Indemnified Party, LIFE COMPANY shall be entitled to participate at
its own expense in the defense of such action.  LIFE COMPANY also shall be
entitled to assume the defense thereof, with counsel satisfactory to the party
named in the action.  After notice from LIFE COMPANY to such party of LIFE
COMPANY's election to assume the defense thereof, the Indemnified Party shall
bear the fees and expenses of any additional counsel retained by it, and LIFE
COMPANY will not be liable to such party under this Agreement for any legal or
other expenses subsequently incurred by such party independently in connection
with the defense thereof other than reasonable costs of investigation.
 
     7.4  Indemnification by TRUST and ADVISER. TRUST and ADVISER agrees to
indemnify and hold harmless LIFE COMPANY, AGSI and each of their respective
directors, officers, employees, and agents and each person, if any, who controls
LIFE COMPANY within the meaning of Section 15 of the '33 Act (collectively, the
"Indemnified Parties") against any and all losses, claims, damages, liabilities
(including amounts paid in settlement with the written consent of TRUST and
ADVISOR which consent shall not be unreasonably withheld) or litigation or
threatened litigation (including legal and other expenses) to which the
Indemnified Parties may become subject under any statute, or regulation, at
common law or otherwise, insofar as such losses, claims, damages, liabilities or
expenses (or actions in respect thereof) or settlements are related to the sale
or acquisition of TRUST's shares or the Variable Contracts, and:
 
     (a)  arise out of or are based upon any untrue statement or alleged untrue
  statement of any material fact contained in the registration statement or
  prospectus or sales literature of TRUST (or any amendment or supplement to any
  of the foregoing), or arise out of or are based upon the omission or the
  alleged omission to state therein a material fact required to be stated
  therein or necessary to make the statements therein not misleading, provided
  that this agreement to indemnify shall not apply as to any Indemnified Party
  if such statement or omission or such alleged statement or omission was made
  in reliance upon and in conformity with information 

                                       10

 
  furnished in writing to ADVISER or TRUST by or on behalf of LIFE COMPANY for
  use in the registration statement or prospectus for TRUST or in sales
  literature (or any amendment or supplement) or otherwise for use in connection
  with the sale of the Variable Contracts or TRUST shares; or
  
     (b)  arise out of or result from (i) statements or representations (other
  than statements or representations contained in the registration statement,
  prospectus or sales literature for the Variable Contracts not supplied by
  ADVISER or TRUST  or persons under its control) or (ii) gross negligence or
  wrongful conduct or willful misfeasance of TRUST or ADVISER or persons under
  their respective control, with respect to the sale or distribution of the
  Variable Contracts or TRUST shares; or
 
     (c)  arise out of any untrue statement or alleged untrue statement of a
  material fact contained in a registration statement, prospectus, or sales
  literature covering the Variable Contracts, or any amendment thereof or
  supplement thereto or the omission or alleged omission to state therein a
  material fact required to be stated therein or necessary to make the
  statements therein not misleading, if such statement or omission or such
  alleged statement or omission was made in reliance upon and in conformity with
  information furnished in writing to LIFE COMPANY for inclusion therein by or
  on behalf of TRUST or ADVISER; or
 
     (d)  arise as a result of (i) a failure by TRUST to provide substantially
  the services and furnish the materials under the terms of this Agreement; or
  (ii) a failure by a Portfolio(s) invested in by the Separate Account  to
  comply with the diversification requirements of Section 817(h) of the Code; or
  (iii) a failure by a Portfolio(s) invested in by the Separate Account to
  qualify as a "regulated investment company" under Subchapter M of the Code; or
 
     (e)  arise out of or result from any material breach of any representation
  and/or warranty made by TRUST in this Agreement or arise out of or result from
  any other material breach of this Agreement by TRUST.

     7.5  Neither TRUST nor ADVISER shall be liable under this indemnification
provision with respect to any losses, claims, damages, liabilities or litigation
incurred or assessed against an Indemnified Party to the extent that such
losses, claims, damages, liabilities or litigation are attributable to such
Indemnified Party's willful misfeasance, bad faith, 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.

     7.6  Neither TRUST nor ADVISER shall be liable under this indemnification
provision with respect to any claim made against an Indemnified Party unless
such Indemnified Party shall have notified TRUST in writing within a reasonable
time after the summons or other first legal process giving information of the
nature of the claim shall have been served upon such Indemnified Party (or after
such Indemnified Party shall have received notice of such service on any
designated agent), but failure to notify TRUST and ADVISER of any such claim
shall not relieve TRUST or ADVISER from any liability which it may have to the
Indemnified Party against whom such action is brought 

                                       11

 
otherwise than on account of this indemnification provision. In case any such
action is brought against the Indemnified Parties, TRUST and ADVISER shall be
entitled to participate at its own expense in the defense thereof. TRUST and
ADVISER also shall be entitled to assume the defense thereof, with counsel
satisfactory to the party named in the action. After notice from TRUST and
ADVISER to such party of TRUST's and ADVISER's election to assume the defense
thereof, the Indemnified Party shall bear the fees and expenses of any
additional counsel retained by it, and neither TRUST or ADVISER will be liable
to such party under this Agreement for any legal or other expenses subsequently
incurred by such party independently in connection with the defense thereof
other than reasonable costs of investigation.


                        Article VIII.  TERM; TERMINATION

     8.1  This Agreement shall be effective as of the date hereof and shall
continue in force until terminated in accordance with the provisions herein.

     8.2  This Agreement shall terminate in accordance with the following
provisions:

     (a)  At the option of LIFE COMPANY or TRUST at any time from the date
  hereof upon 180 days' notice, unless a shorter time is agreed to by the
  parties;
 
     (b)  At the option of LIFE COMPANY, if TRUST shares are not reasonably
  available to meet the requirements of the Variable Contracts as determined by
  LIFE COMPANY.  Prompt notice of election to terminate shall be furnished by
  LIFE COMPANY, said termination to be effective ten (10) days after receipt of
  notice unless TRUST makes available a sufficient number of shares to
  reasonably meet the requirements of the Variable Contracts within said ten
  (10) day period;
 
     (c)  At the option of LIFE COMPANY, upon the institution of formal
  proceedings against TRUST by the SEC, the NASD, or any other regulatory body,
  the expected or anticipated ruling, judgment or outcome of which would, in
  LIFE COMPANY's reasonable judgment, materially impair TRUST's ability to meet
  and perform TRUST's obligations and duties hereunder.  Prompt notice of
  election to terminate shall be furnished by LIFE COMPANY with said termination
  to be effective upon receipt of notice;
 
     (d)  At the option of TRUST, upon the institution of formal proceedings
  against LIFE COMPANY and/or its broker-dealer affiliates by the SEC, the NASD,
  or any other regulatory body, the expected or anticipated ruling, judgment or
  outcome of which would, in TRUST's reasonable judgment, materially impair LIFE
  COMPANY's ability to meet and perform its obligations and duties hereunder.
  Prompt notice of election to terminate shall be furnished by TRUST with said
  termination to be effective upon receipt of notice;

     (e)  In the event TRUST's shares are not registered, issued or sold in
  accordance with applicable state or federal law, or such law precludes the use
  of such shares as the underlying investment medium of Variable Contracts
  issued or to be issued by LIFE COMPANY. Termination shall be effective upon
  such occurrence without notice;

                                       12

 
     (f)  At the option of TRUST if the Variable Contracts cease to qualify as
  annuity contracts or life insurance contracts, as applicable, under the Code,
  or if TRUST reasonably believes that the Variable Contracts may fail to so
  qualify.  Termination shall be effective upon receipt of notice by LIFE
  COMPANY;
 
     (g)  At the option of LIFE COMPANY, upon TRUST's breach of any material
  provision of this Agreement, which breach has not been cured to the
  satisfaction of LIFE COMPANY within ten days after written notice of such
  breach is delivered to TRUST;
 
     (h)  At the option of TRUST, upon LIFE COMPANY's breach of any material
  provision of this Agreement, which breach has not been cured to the
  satisfaction of TRUST within ten days after written notice of such breach is
  delivered to LIFE COMPANY;
 
     (i)  At the option of TRUST, if the Variable Contracts are not registered,
  issued or sold in accordance with applicable federal and/or state law.
  Termination shall be effective immediately upon such occurrence without
  notice;

     In the event this Agreement is assigned without the prior written consent
of LIFE COMPANY, TRUST, and ADVISER, termination shall be effective immediately
upon such occurrence without notice.

     8.3  Notwithstanding any termination of this Agreement pursuant to Section
8.2 hereof, TRUST at its option may elect to continue to make available
additional TRUST shares, as provided below, for so long as TRUST desires
pursuant to the terms and conditions of this Agreement, for all Variable
Contracts in effect on the effective date of termination of this Agreement
(hereinafter referred to as "Existing Contracts").  Specifically, without
limitation, if TRUST so elects to make additional TRUST shares available, the
owners of the Existing Contracts or LIFE COMPANY, whichever shall have legal
authority to do so, shall be permitted to reallocate investments in TRUST,
redeem investments in TRUST and/or invest in TRUST upon the payment of
additional premiums under the Existing Contracts.  In the event of a termination
of this Agreement pursuant to Section 8.2  hereof, TRUST and ADVISER, as
promptly as is practicable under the circumstances, shall notify LIFE COMPANY
whether TRUST elects to continue to make TRUST shares available after such
termination.  If TRUST shares continue to be made available after such
termination, the provisions of this Agreement shall remain in effect and
thereafter either TRUST or LIFE COMPANY may terminate the Agreement, as so
continued pursuant to this Section 8.3, upon sixty (60) days' prior written
notice to the other party.

     8.4 Except as necessary to implement Variable Contract owner initiated
transactions, or as required by state insurance laws or regulations,  LIFE
COMPANY shall not redeem the shares attributable to the Variable Contracts (as
opposed to the shares attributable to LIFE COMPANY's assets held in the Separate
Accounts), and LIFE COMPANY shall not prevent Variable Contract owners from
allocating payments to a Portfolio that was otherwise available under the
Variable Contracts until thirty (30) days after the LIFE COMPANY shall have
notified TRUST of its intention to do so.

reference only and in no way define or delineate any of the provisions hereof or
otherwise affect their construction or effect.

                                       14

 
     10.2  This Agreement may be executed simultaneously in two or more
counterparts, each of which taken together shall constitute one and the same
instrument.

     10.3  If any provision of this Agreement shall be held or made invalid by a

Sections 10.5, 10.6 and 10.7 shall remain in effect after termination.

     10.9  No provision of this Agreement may be amended or modified in any
manner except by a written agreement properly authorized and executed by TRUST,
ADVISER and the LIFE COMPANY.

                                       15

 
     10.10  No failure or delay by a party in exercising any right or remedy
under this Agreement will operate as a waiver thereof and no single or partial
exercise of rights shall preclude a further or subsequent exercise.  The rights
and remedies provided in this Agreement are cumulative and not exclusive of any
rights or remedies provided by law.

     IN WITNESS WHEREOF, the parties have caused their duly authorized officers
to execute this Fund Participation Agreement as of the date and year first above
written.
