ARTICLE I.  SALE OF FUND SHARES

               1.1. The Fund has granted to the Underwriter exclusive authority
to distribute the Fund's shares, and has agreed to instruct, and has so
instructed, the Underwriter to make available to the Company for purchase on
behalf of the Account Fund shares of those Designated Portfolios selected by the
Underwriter. Pursuant to such authority and instructions, and subject to Article
X hereof, the Underwriter agrees to make available to the Company for purchase
on behalf of the Account, shares of those Designated Portfolios listed on
Schedule A to this Agreement, such purchases to be effected at net asset value
in accordance with Section 1.3 of this Agreement. Notwithstanding the foregoing,
(i) Fund series (other than those listed on Schedule A) in existence now or that
may be established in the future will be made available to the Company only as
the Underwriter may so provide, and (ii) the Board of Trustees of the Fund (the
"Board") may suspend or terminate the offering of Fund shares of any Designated
Portfolio or class thereof, if such action is required by law or by regulatory
authorities having jurisdiction or if, 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, suspension or termination is necessary in the best
interests of the shareholders of such Designated Portfolio.

          1.2. The Fund shall redeem, at the Company's request, any full or
fractional Designated Portfolio shares held by the Company on behalf of the
Account, such redemptions to be effected at net asset value in accordance with
Section 1.3 of this Agreement. Notwithstanding the foregoing, (i) the Company
shall not redeem Fund shares attributable to Contract owners except in the
circumstances permitted in Section 10.3 of this Agreement, and (ii) the Fund may
delay redemption of Fund shares of any Designated Portfolio to the extent
permitted by the 1940 Act, and any rules, regulations or orders thereunder.

          1.3. PURCHASE AND REDEMPTION PROCEDURES

               (a) The Fund hereby appoints the Company as an agent of the Fund
     for the limited purpose of receiving purchase and redemption requests on
     behalf of the Account (but not with respect to any Fund shares that may be
     held in the general account of the Company) for shares of those Designated
     Portfolios made available hereunder, based on allocations of amounts to the
     Account or subaccounts thereof under the Contracts and other transactions
     relating to the


                                      -2-
<PAGE>

     Contracts or the Account. Receipt of any such request (or relevant
     transactional information therefor) on any day the New York Stock Exchange
     is open for trading and on which the Fund calculates its net asset value
     pursuant to the rules of the SEC (a "Business Day") by the Company as such
     limited agent of the Fund prior to the time that the Fund ordinarily
     calculates its net asset value as described from time to time in the Fund
     Prospectus (which as of the date of execution of this Agreement is 4:00
     p.m. Eastern Time) shall constitute receipt by the Fund on that same
     Business Day, provided that the Fund receives notice of such request by
     9:00 a.m. Eastern Time on the next following Business Day.

               (b) The Company shall pay for shares of each Designated Portfolio
     on the same day that it notifies the Fund of a purchase request for such
     shares. Payment for Designated Portfolio shares shall be made in federal
     funds transmitted to the Fund by wire to be received by the Fund by 4:00
     p.m. Eastern Time on the day the Fund is notified of the purchase request
     for Designated Portfolio shares (unless the Fund determines and so advises
     the Company that sufficient proceeds are available from redemption of
     shares of other Designated Portfolios effected pursuant to redemption
     requests tendered by the Company on behalf of the Account). If federal
     funds are not received on time, such funds will be invested, and Designated
     Portfolio shares purchased thereby will be issued, as soon as practicable
     and the Company shall promptly, upon the Fund's request, reimburse the Fund
     for any charges, costs, fees, interest or other expenses incurred by the
     Fund in connection with any advances to, or borrowing or overdrafts by, the
     Fund, or any similar expenses incurred by the Fund, as a result of
     portfolio transactions effected by the Fund based upon such purchase
     request. Upon receipt of federal funds so wired, such funds shall cease to
     be the responsibility of the Company and shall become the responsibility of
     the Fund.

               (c) Payment for Designated Portfolio shares redeemed by the
     Account or the Company shall be made in federal funds transmitted by wire
     to the Company or any other designated person on the next Business Day
     after the Fund is properly notified of the redemption order of such shares
     (unless redemption proceeds are to be applied to the purchase of shares of
     other Designated Portfolios in accordance with Section 1.3(b) of this
     Agreement), except that the Fund reserves the right to redeem Designated
     Portfolio shares in assets other than cash and to delay payment of
     redemption proceeds to the extent permitted under Section 22(e) of the 1940
     Act and any Rules thereunder, and in accordance with the procedures and
     policies of the Fund as described in the then current prospectus. The Fund
     shall not bear any responsibility whatsoever for the proper disbursement or
     crediting of redemption proceeds by the Company; the Company alone shall be
     responsible for such action.

               (d) Any purchase or redemption request for Designated Portfolio
     shares held or to be held in the Company's general account shall be
     effected at the net asset value per share next determined after the Fund's
     receipt of such request, provided that, in the case of a purchase request,
     payment for Fund shares so requested is received by the Fund in federal
     funds prior to close of business for determination of such value, as
     defined from time to time in the Fund Prospectus.

          1.4. The Fund shall use its best efforts to make the net asset value
per share for each Designated Portfolio available to the Company by 7:00 p.m.
Eastern Time each Business Day, and in any event, as soon as reasonably
practicable after the net asset value per share for such Designated Portfolio is
calculated, and shall calculate such net asset value in accordance with the
Fund's Prospectus. Neither the Fund, any Designated Portfolio, the Underwriter,
nor any of their affiliates shall be liable for any


                                      -3-
<PAGE>

information provided to the Company pursuant to this Agreement which information
is based on incorrect information supplied by the Company or any other
Participating Insurance Company to the Fund or the Underwriter.

          1.5. The Fund shall furnish notice (by wire or telephone followed by
written confirmation) to the Company as soon as reasonably practicable of any
income dividends or capital gain distributions payable on any Designated
Portfolio shares. The Company, on its behalf and on behalf of the Account,
hereby elects to receive all such dividends and distributions as are payable on
any Designated Portfolio shares in the form of additional shares of that
Designated Portfolio. The Company reserves the right, on its behalf and on
behalf of the Account, to revoke this election and to receive all such dividends
and capital gain distributions in cash. The Fund shall notify the Company
promptly of the number of Designated Portfolio shares so issued as payment of
such dividends and distributions.

          1.6. Issuance and transfer of Fund shares shall be by book entry only.
Stock certificates will not be issued to the Company or the Account. Purchase
and redemption orders for Fund shares shall be recorded in an appropriate ledger
for the Account or the appropriate subaccount of the Account.

          1.7. (a) The parties hereto acknowledge that the arrangement
contemplated by this Agreement is not exclusive; the Fund's shares may be sold
to other insurance companies (subject to Section 1.8 hereof) and the cash value
of the Contracts may be invested in other investment companies, provided,
however, that until this Agreement is terminated pursuant to Article X, the
Company shall promote the Designated Portfolios on the same basis as other
funding vehicles available under the Contracts. Funding vehicles other than
those listed on Schedule A to this Agreement may be available for the investment
of the cash value of the Contracts, provided, however, (i) any such vehicle or
series thereof, has investment objectives or policies that are substantially
different from the investment objectives and policies of the Designated
Portfolios available hereunder;; or (iii) unless such other investment company
was available as a Funding vehicle for the Contracts prior to the date of this
Agreement and the Company has so informed the Fund and the Underwriter prior to
their signing this Agreement, the Fund or Underwriter consents in writing to the
use of such other vehicle, such consent not to be unreasonably withheld.

               (b) The Company shall not, without prior notice to the
Underwriter (unless otherwise required by applicable law), take any action to
operate the Account as a management investment company under the 1940 Act.

               (c) The Company shall not, without prior notice to the
Underwriter (unless otherwise required by applicable law), induce Contract
owners to change or modify the Fund or change the Fund's distributor or
investment adviser.

               (d) The Company shall not, without prior notice to the Fund,
induce Contract owners to vote on any matter submitted for consideration by the
shareholders of the Fund in a manner other than as recommended by the Board of
Trustees of the Fund.


                                      -4-

          1.8. The Underwriter and the Fund shall sell Fund shares only to
Participating Insurance Companies and their separate accounts and to persons or
plans ("Qualified Persons") that communicate to the Underwriter and the Fund
that they qualify to purchase shares of the Fund under Section 817(h) of the
Internal Revenue Code of 1986, as amended (the "Code") and the regulations
thereunder without impairing the ability of the Account to consider the
portfolio investments of the Fund as constituting investments of the Account for
the purpose of satisfying the diversification requirements of Section 817(h).
The Underwriter and the Fund shall not sell Fund shares to any insurance company
or separate account unless an agreement complying with Article VI of this
Agreement is in effect to govern such sales, to the extent required. The Company
hereby represents and warrants that it and the Account are Qualified Persons.
The Fund reserves the right to cease offering shares of any Designated Portfolio
in the discretion of the Fund.

               (iii) vote Fund shares for which no instructions have been
                     received in the same proportion as Fund shares of such
                     portfolio for which instructions have been received,

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 or to the

          5.3. The Company shall bear the expenses of distributing the Fund's
prospectus to owners of Contracts issued by the Company and of distributing the
Fund's proxy materials and reports to such Contract owners.

ARTICLE VI.  DIVERSIFICATION AND QUALIFICATION

          6.1 The Fund will invest its assets in such a manner as to ensure that
the Contracts will be treated as annuity or life insurance contracts, whichever
is appropriate, under the Code and the regulations issued thereunder (or any
successor provisions). Without limiting the scope of the foregoing, each
Designated Portfolio has complied and will continue to comply with Section
817(h) of the Code and Treasury Regulation ss.1.817-5, and any Treasury
interpretations thereof, relating to the diversification requirements for
variable annuity, endowment, or life insurance contracts, and any amendments or
other modifications or successor provisions to such Section or Regulations. In
the event of a breach of this Article VI by the Fund, it will take all
reasonable steps (a) to notify the Company of such breach and (b) to adequately
diversify the Fund so as to achieve compliance within the grace period afforded
by Regulation 1.817-5.

          6.2. The Fund represents that it is or will be qualified as a
Regulated Investment Company under Subchapter M of the Code, and that it will
make every effort to maintain such qualification (under Subchapter M or any
successor or similar provisions) and that it will notify the Company immediately
upon having a reasonable basis for believing that it has ceased to so qualify or
that it might not so qualify in the future.

          6.3. The Company represents that the Contracts are currently, and at
the time of issuance shall be, treated as life insurance or annuity insurance
contracts, under applicable provisions of


                                      -9-
<PAGE>

the Code, and that it will make every effort to maintain such treatment, and
that it will notify the Fund and the Underwriter immediately upon having a
reasonable basis for believing the Contracts have ceased to be so treated or
that they might not be so treated in the future. The Company agrees that any
prospectus offering a contract that is a "modified endowment contract" as that
term is defined in Section 7702A of the Code (or any successor or similar
provision), shall identify such contract as a modified endowment contract.

ARTICLE VII.  POTENTIAL CONFLICTS

The following provisions shall apply only upon issuance of the Mixed and Shared
Funding Order and the sale of shares of the Fund to variable life insurance
separate accounts, and then only to the extent required under the 1940 Act.

          7.1. The Board will monitor the Fund for the existence of any material
irreconcilable conflict between the interests of the Contract owners of all
separate accounts investing in the Fund. An irreconcilable material conflict may
arise for a variety of reasons, including, but not limited to: (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, no-action or interpretative letter, 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 any Portfolio are being managed; (e) a difference in voting
instructions given by variable annuity contract and variable life insurance
contract owners; or (f) a decision by an insurer to disregard the voting
instructions of contract owners. The Board shall promptly inform the Company if
it determines that an irreconcilable material conflict exists and the
implications thereof.

          7.2. The Company will report any potential or existing conflicts of
which it is aware to the Board. The Company will assist the Board in carrying
out its responsibilities under the Mixed and Shared Funding Exemptive Order, by
providing the Board with all information reasonably necessary for the Board to
consider any issues raised. This includes, but is not limited to, an obligation
by the Company to inform the Board whenever Contract owner voting instructions
are disregarded.

          7.3. If it is determined by a majority of the Board, or a majority of
its disinterested members, that a material irreconcilable conflict exists, the
Company and other Participating Insurance Companies shall, at their expense and
to the extent reasonably practicable (as determined by a majority of the
disinterested Board members), take whatever steps are necessary to remedy or
eliminate the irreconcilable material conflict, up to and including: (1)
withdrawing the assets allocable to some or all of the separate accounts from
the Fund or any Portfolio and reinvesting such assets in a different investment
medium, including (but not limited to) another Portfolio of the Fund, or
submitting the question whether such segregation should be implemented to a vote
of all affected contract owners and, as appropriate, segregating the assets of
any appropriate group (i.e., annuity contract owners, life insurance contract
owners, or variable contract owners of one or more Participating Insurance
Companies) that votes in favor of such segregation, or offering to the affected
contract owners the option of making such a change; and (2) establishing a new
registered management investment company or managed separate account.

          7.4. If a material irreconcilable conflict arises because of a
decision by the Company to disregard Contract owner voting instructions and that
decision represents a minority position or would preclude a majority vote, the
Company may be required, at the Fund's election, to withdraw the Account's
investment in the Fund and terminate this Agreement with respect to each
Account; provided, however,


                                      -10-
<PAGE>

that such withdrawal and termination shall be limited to the extent required by
the foregoing material irreconcilable conflict as determined by a majority of
the disinterested members of the Board. Any such withdrawal and termination must
take place within six (6) months after the Fund gives written notice that this
provision is being implemented, and until the end of that six month period the
Fund shall continue to accept and implement orders by the Company for the
purchase (and redemption) of shares of the Fund.

          7.5. If a material irreconcilable conflict arises because a particular
state insurance regulator's decision applicable to the Company conflicts with
the majority of other state regulators, then the Company will withdraw the
affected Account's investment in the Fund and terminate this Agreement with
respect to such Account within six months after the Board informs the Company in
writing that it has determined that such decision has created an irreconcilable
material conflict; provided, however, that such withdrawal and termination shall
be limited to the extent required by the foregoing material irreconcilable
conflict as determined by a majority of the disinterested members of the Board.
Until the end of the foregoing six month period, the Fund shall continue to
accept and implement orders by the Company for the purchase (and redemption) of
shares of the Fund.

          7.6. For purposes of Section 7.3 through 7.6 of this Agreement, a
majority of the disinterested members of the Board shall determine whether any
proposed action adequately remedies any irreconcilable material conflict, but in
no event will the Fund be required to establish a new funding medium for the
Contracts. The Company shall not be required by Section 7.3 to establish a new
funding medium for the Contract if an offer to do so has been declined by vote
of a majority of Contract owners materially adversely affected by the
irreconcilable material conflict. In the event that the Board determines that
any proposed action does not adequately remedy any irreconcilable material
conflict, then the Company will withdraw the Account's investment in the Fund
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 by any such
material irreconcilable conflict as determined by a majority of the
disinterested members of the Board.

          7.7. If and to the extent the Mixed and Shared Funding Exemption Order
or any amendment thereto contains terms and conditions different from Sections
3.4, 3.5, 3.6, 7.1, 7.2, 7.3, 7.4, and 7.5 of this Agreement, then the Fund
and/or the Participating Insurance Companies, as appropriate, shall take such
steps as may be necessary to comply with the Mixed and Shared Funding Exemptive
Order, and Sections 3.4, 3.5, 3.6, 7.1, 7.2, 7.3, 7.4 and 7.5 of this Agreement
shall continue in effect only to the extent that terms and conditions
substantially identical to such Sections are contained in the Mixed and Shared
Funding Exemptive Order or any amendment thereto. 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 Fund
and/or the Participating Insurance Companies, as appropriate, shall take such
steps as may be necessary to comply with Rules 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, 7.4, and 7.5 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.

ARTICLE VIII.  INDEMNIFICATION

               8.1 INDEMNIFICATION BY THE COMPANY

               8.1(a). The Company agrees to indemnify and hold harmless the
Fund and the Underwriter and each of its trustees/directors and officers, and
each person, if any, who controls the Fund or Underwriter within the meaning of
Section 15 of the 1933 Act or who is under common control with the Underwriter
(collectively, the "Indemnified Parties" for purposes of this Section 8.1)
against any and all losses, claims, damages, liabilities (including amounts paid
in settlement with the written consent of the Company) or 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:

               (i)   arise out of or are based upon any untrue statement or
               alleged untrue statements of any material fact contained in the
               registration statement, prospectus (which shall include a written
               description of a Contract that is not registered under the 1933
               Act), or SAI for the Contracts or contained in the Contracts or
               sales literature for the 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 to the Company by or on behalf of the Fund
               for use in the registration statement, prospectus or SAI for the
               Contracts or in the Contracts or sales literature (or any
               amendment or supplement) or otherwise for use in connection with
               the sale of the Contracts or Fund shares; or

               (ii)  arise out of or as a result of statements or
               representations (other than statements or representations
               contained in the registration statement, prospectus, SAI, or
               sales literature of the Fund not supplied by the Company or
               persons under its control) or wrongful conduct of the Company or
               its agents or persons under the Company's authorization or
               control, with respect to the sale or distribution of the
               Contracts or Fund Shares; or

               (iii) arise out of any untrue statement or alleged untrue
               statement of a material fact contained in a registration
               statement, prospectus, SAI, or sales literature of the Fund 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 a statement or omission was made in reliance
               upon information furnished to the Fund by or on behalf of the
               Company; or

               (iv)  arise as a result of any material failure by the Company to
               provide the services and furnish the materials under the terms of
               this Agreement (including a failure, whether unintentional or in
               good faith or otherwise, to comply with the qualification
               requirements specified in Article VI of this Agreement); or


                                      -12-
<PAGE>

               (v)   arise out of or result from any material breach of any
               representation and/or warranty made by the Company in this
               Agreement or arise out of or result from any other material
               breach of this Agreement by the Company; or

as limited by and in accordance with the provisions of Sections 8.1(b) and
8.1(c) hereof.

               8.1(b). The Company shall not be liable under this
indemnification provision with respect to any losses, claims, damages,
liabilities or litigation to which an Indemnified Party would otherwise be
subject by reason of 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 its obligations or
duties under this Agreement.

               8.1(c). The 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 the 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 the Company of any
such claim shall not relieve the 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, the Company shall be entitled to participate, at
its own expense, in the defense of such action. The Company also shall be
entitled to assume the defense thereof, with counsel satisfactory to the party
named in the action. After notice from the Company to such party of the
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 the
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.

               8.1(d). The Indemnified Parties will promptly notify the Company
of the commencement of any litigation or proceedings against them in connection
with the issuance or sale of the Fund shares or the Contracts or the operation
of the Fund.

          8.2. Indemnification by the Underwriter

               8.2(a). The Underwriter agrees to indemnify and hold harmless the
Company and each of its directors and officers and each person, if any, who
controls the Company within the meaning of Section 15 of the 1933 Act
(collectively, the "Indemnified Parties" for purposes of this Section 8.2)
against any and all losses, claims, damages, liabilities (including amounts paid
in settlement with the written consent of the Underwriter) or 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:

               (i)   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 SAI or sales literature
               of the Fund (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,


                                      -13-
<PAGE>

               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 to the Underwriter or Fund
               by or on behalf of the Company for use in the registration
               statement, prospectus or SAI for the Fund or in sales literature
               (or any amendment or supplement) or otherwise for use in
               connection with the sale of the Contracts or Fund shares; or

               (ii)  arise out of or as a result of statements or
               representations (other than statements or representations
               contained in the registration statement, prospectus, SAI or sales
               literature for the Contracts not supplied by the Underwriter or
               persons under its control) or wrongful conduct of the Fund or
               Underwriter or persons under their control, with respect to the
               sale or distribution of the Contracts or Fund shares; or

               (iii)  arise out of any untrue statement or alleged untrue
               statement of a material fact contained in a registration
               statement, prospectus, SAI or sales literature covering the
               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 statement
               or statements therein not misleading, if such statement or
               omission was made in reliance upon information furnished to the
               Company by or on behalf of the Fund or the Underwriter; or

               (iv)  arise as a result of any failure by the Fund or the
               Underwriter to provide the services and furnish the materials
               under the terms of this Agreement (including a failure of the
               Fund, whether unintentional or in good faith or otherwise, to
               comply with the diversification and other qualification
               requirements specified in Article VI of this Agreement); or

               (v)  arise out of or result from any material breach of any
               representation and/or warranty made by the Underwriter in this
               Agreement or arise out of or result from any other material
               breach of this Agreement by the Underwriter;

as limited by and in accordance with the provisions of Sections 8.2(b) and
8.2(c) hereof.

               8.2(b). The Underwriter shall not be liable under this
indemnification provision with respect to any losses, claims, damages,
liabilities or litigation to which an Indemnified Party would otherwise be
subject by reason of such Indemnified Party's willful misfeasance, bad faith, or
gross negligence in the performance or such Indemnified Party's duties or by
reason of such Indemnified Party's reckless disregard of obligations and duties
under this Agreement or to the Company or the Account, whichever is applicable.

               8.2(c). The Underwriter 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 the Underwriter 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 the Underwriter of
any such claim shall not relieve the Underwriter from any liability


                                      -14-
<PAGE>

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 the Indemnified Party, the Underwriter will be
entitled to participate, at its own expense, in the defense thereof. The
Underwriter also shall be entitled to assume the defense thereof, with counsel
satisfactory to the party named in the action. After notice from the Underwriter
to such party of the Underwriter's election to assume the defense thereof, the
Indemnified Party shall bear the fees and expenses of any additional counsel
retained by it, and the Underwriter 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.

               The Company agrees promptly to notify the Underwriter of the
commencement of any litigation or proceedings against it or any of its officers
or directors in connection with the issuance or sale of the Contracts or the
operation of the Account.

          8.3. INDEMNIFICATION BY THE FUND

               8.3(a). The Fund agrees to indemnify and hold harmless the
Company and each of its directors and officers and each person, if any, who
controls the Company within the meaning of Section 15 of the 1933 Act
(collectively, the "Indemnified Parties" for purposes of this Section 8.3)
against any and all losses, claims, expenses, damages, liabilities (including
amounts paid in settlement with the written consent of the Fund) or litigation
(including legal and other expenses) to which the Indemnified Parties may be
required to pay or may become subject under any statute or regulation, at common
law or otherwise, insofar as such losses, claims, expenses, damages, liabilities
or expenses (or actions in respect thereof) or settlements, are related to the
operations of the Fund and:

               (i)   arise as a result of any failure by the Fund to provide
               the services and furnish the materials under the terms of this
               Agreement (including a failure, whether unintentional or in good
               faith or otherwise, to comply with the diversification and other
               qualification requirements specified in Article VI of this
               Agreement); or

               (ii)  arise out of or as a result of statements or

               contained in the registration statement, prospectus, SAI or sales
               literature for the Contracts not supplied by the Fund or persons
               under its control) or wrongful conduct of the Fund or persons
               under its control, with respect to the sale or distribution of
               Fund shares; or

               (iii) arise out of any untrue statement or alleged untrue
               statement of a material fact contained in a registration
               statement, prospectus, SAI, or sales literature of the Company 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 a statement or omission was made in reliance
               upon information furnished to the Company by or on behalf of the
               Fund; or

               (iv)  arise as a result of any material failure by the Fund to
               provide the services and furnish the materials under the terms of
               this Agreement (including a


                                      -15-
<PAGE>

               failure, whether unintentional or in good faith or otherwise, to
               comply with the qualification requirements specified in Article
               VI of this Agreement); or

               (v)   arise out of or result from any material breach of any
               representation and/or warranty made by the Fund in this Agreement
               or arise out of or result from any other material breach of this
               Agreement by the Fund;

as limited by and in accordance with the provisions of Sections 8.3(b) and
8.3(c) hereof.

               8.3(b). The Fund shall not be liable under this indemnification
provision with respect to any losses, claims, damages, liabilities or litigation
to which an Indemnified Party would otherwise be subject by reason of 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 or to
the Company, the Fund, the Underwriter or the Account, whichever is applicable.

               8.3(c). The Fund 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 the Fund 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 the Fund of any
such claim shall not relieve the Fund 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 the Indemnified Parties, the Fund will be entitled to participate, at
its own expense, in the defense thereof. The Fund also shall be entitled to
assume the defense thereof, with counsel satisfactory to the party named in the
action. After notice from the Fund to such party of the Fund's election to
assume the defense thereof, the Indemnified Party shall bear the fees and

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.

               8.3(d). The Company and the Underwriter agree promptly to notify
the Fund of the commencement of any litigation or proceeding against it or any

<PAGE>

          10.1 This Agreement shall continue in full force and effect until the
first to occur of:

          (a)  termination by any party, for any reason with respect to some or
               all Designated Portfolios, by three (3) months advance written
               notice delivered to the other parties; or

          (b)  termination by the Company by written notice to the Fund and the
               Underwriter based upon the Company's determination that shares of
               the Fund are not reasonably available to meet the requirements of
               the Contracts; or

          (c)  termination by the Company by written notice to the Fund and the
               Underwriter in the event any of the Designated Portfolio's shares
               are not registered, issued or sold in accordance with applicable
               state and/or federal law or such law precludes the use of such
               shares as the underlying investment media of the Contracts issued
               or to be issued by the Company; or

          (d)  termination by the Fund or Underwriter in the event that formal
               administrative proceedings are instituted against the Company by
               the NASD, the SEC, the Insurance Commissioner or like official of
               any state or any other regulatory body regarding the Company's
               duties under this Agreement or related to the sale of the
               Contracts, the operation of any Account, or the purchase of the
               Fund's shares; provided, however, that the Fund or Underwriter
               determines in its sole judgment exercised in good faith, that any
               such administrative proceedings will have a material adverse
               effect upon the ability of the Company to perform its obligations
               under this Agreement; or

          (e)  termination by the Company in the event that formal
               administrative proceedings are instituted against the Fund or
               Underwriter by the NASD, the SEC, or any state securities or
               insurance department or any other regulatory body; provided,
               however, that the Company determines in its sole judgment
               exercised in good faith, that any such administrative proceedings
               will have a material adverse effect upon the ability of the Fund
               or Underwriter to perform its obligations under this Agreement;
               or

          (f)  termination by the Company by written notice to the Fund and the
               Underwriter with respect to any Designated Portfolio in the event
               that such Portfolio ceases to qualify as a Regulated Investment
               Company under Subchapter M or fails to comply with the Section
               817(h) diversification requirements specified in Article VI
               hereof, or if the Company reasonably believes that such Portfolio
               may fail to so qualify or comply; or

          (g)  termination by the Fund or Underwriter by written notice to the
               Company in the event that the Contracts fail to meet the
               qualifications specified in Article VI hereof; or

          (h)  termination by either the Fund or the Underwriter by written
               notice to the Company, if either one or both of the Fund or the
               Underwriter 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


                                      -17-
<PAGE>

               condition, or prospects since the date of this Agreement or is
               the subject of material adverse publicity; or

          (i)  termination by the Company by written notice to the Fund and the
               Underwriter, if the Company shall determine, in its sole judgment
               exercised in good faith, that the Fund, Adviser, or the
               Underwriter 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

          (j)  termination by the Fund or the Underwriter by written notice to
               the Company, if the Company gives the Fund and the Underwriter
               the written notice specified in Section 1.7(a)(ii) hereof and at
               the time such notice was given there was no notice of termination
               outstanding under any other provision of this Agreement;
               provided, however, any termination under this Section 10.1(j)
               shall be effective forty-five days after the notice specified in
               Section 1.7(a)(ii) was given; or

          (k)  termination by the Company upon any substitution of the shares of
               another investment company or series thereof for shares of a
               Designated Portfolio of the Fund in accordance with the terms of
               the Contracts, provided that the Company has given at least 45
               days prior written notice to the Fund and Underwriter of the date
               of substitution; or

          (l)  termination by any party in the event that the Fund's Board of
               Trustees determines that a material irreconcilable conflict
               exists as provided in Article VII.

          10.2. Notwithstanding any termination of this Agreement, the Fund and
the Underwriter shall, at the option of the Company, continue to make available
additional shares of the Fund pursuant to the terms and conditions of this
Agreement, for all Contracts in effect on the effective date of termination of
this Agreement (hereinafter referred to as "Existing Contracts"), unless the
Underwriter requests that the Company seek an order pursuant to Section 26(b) of
the 1940 Act to permit the substitution of other securities for the shares of
the Designated Portfolios. The Underwriter agrees to split the cost of seeking
such an order, and the Company agrees that it shall reasonably cooperate with
the Underwriter and seek such an order upon request. Specifically, the owners of
the Existing Contracts may be permitted to reallocate investments in the Fund,
redeem investments in the Fund and/or invest in the Fund upon the making of
additional purchase payments under the Existing Contracts (subject to any such
election by the Underwriter). The parties agree that this Section 10.2 shall not
apply to any terminations under Article VII and the effect of such Article VII
terminations shall be governed by Article VII of this Agreement. The parties
further agree that this Section 10.2 shall not apply to any terminations under
Section 10.1(g) of this Agreement.

          10.3. The Company shall not redeem Fund shares attributable to the
Contracts (as opposed to Fund shares attributable to the Company's assets held
in the Account) except (i) as necessary to implement Contract owner initiated or
approved transactions, (ii) as required by state and/or federal laws or
regulations or judicial or other legal precedent of general application
(hereinafter referred to as a "Legally Required Redemption"), (iii) upon 45 days
prior written notice to the Fund and Underwriter, as permitted by an order of
the SEC pursuant to Section 26(b) of the 1940 Act, but only if a substitution of
other securities for the shares of the Designated Portfolios is consistent with
the terms of the Contracts, or (iv) as permitted under the terms of the
Contract. Upon request, the Company will promptly furnish to


                                      -18-
<PAGE>

the Fund and the Underwriter reasonable assurance that any redemption pursuant
to clause (ii) above is a Legally Required Redemption. Furthermore, except in
cases where permitted under the terms of the Contacts, the Company shall not
prevent Contract owners from allocating payments to a Portfolio that was
otherwise available under the Contracts without first giving the Fund or the
Underwriter 45 days notice of its intention to do so.

          10.4. Notwithstanding any termination of this Agreement, each party's
obligation under Article VIII to indemnify the other parties shall survive.

or inquiry relating to this Agreement or the transactions contemplated hereby.

operations of the Company are being conducted in a manner consistent with the
DELAWARE variable annuity laws and regulations and any other applicable law or
regulations.

          12.7. The rights, remedies and obligations contained in this Agreement

               federal regulatory body or otherwise made available to the
               public, as soon as practicable and in any event within 90 days
               after the end of each fiscal year; and

          (b)  any registration statement (without exhibits) and financial
               reports of the Company filed with the Securities and Exchange
