WHEREAS,  the  Directors  of Hartford HLS Series Fund II have  determined,  with
respect to the Acquired Fund, that the sale,  assignment,  conveyance,  transfer
and  delivery  of all of the  property  and  assets  of the  Acquired  Fund  for

NOW,  THEREFORE,  in  consideration  of the  premises and of the  covenants  and
agreements  hereinafter  set forth,  the parties  hereto  covenant  and agree as
follows:

1.   TRANSFER OF ASSETS OF THE ACQUIRED FUND TO THE  ACQUIRING  FUND IN EXCHANGE
     FOR ACQUIRING FUND SHARES,  THE ASSUMPTION OF ALL ACQUIRED FUND LIABILITIES
     AND THE LIQUIDATION OF THE ACQUIRED FUND

          1.1.   Subject  to  the  requisite   approval  of  the  Acquired  Fund
shareholders  and the other  terms and  conditions  herein  set forth and on the
basis of the representations and warranties  contained herein, the Acquired Fund
agrees to sell,  assign,  convey,  transfer  and deliver all of the property and
assets of the  Acquired  Fund,  as set forth in  paragraph  1.2  herein,  to the
Acquiring  Fund,  and the  Acquiring  Fund agrees in exchange  therefor:  (i) to
deliver to the Acquired Fund the number of full and  fractional  Acquiring  Fund
Shares  determined by dividing the value of the Acquired  Fund's net assets with
respect to the  corresponding  class of Acquired  Fund  Shares,  computed in the
manner and as of the time and date set forth in paragraph 2.1 herein, by the net
asset value of one Acquiring Fund Share of the corresponding class,  computed in
the manner and as of the time and date set forth in  paragraph  2.2 herein;  and
(ii) to assume all liabilities of the Acquired Fund, as set forth in

                                      1


paragraph  1.3  herein.  Such  transactions  shall take place on the date of the
closing provided for in paragraph 3.1 herein ("Closing Date").

          1.2.   The  property  and  assets  of  Hartford  HLS  Series  Fund  II
attributable  to the Acquired  Fund to be acquired by the  Acquiring  Fund shall
consist of all property and assets, including,  without limitation,  all rights,
cash,  securities,  commodities and futures interests and dividends or interests
receivable  that are owned by the  Acquired  Fund and any  deferred  or  prepaid
expenses  shown as an asset on the books of the Acquired  Fund on the  Valuation
Date as defined in paragraph  2.1  (collectively,  "Assets").  The Acquired Fund
will sell,  assign,  convey,  transfer  and  deliver to the  Acquiring  Fund any
rights, stock dividends, or other securities received by the Acquired Fund after
the Closing Date as stock dividends or other distributions on or with respect to
the property and assets transferred,  which rights,  stock dividends,  and other
securities  shall be deemed  included in the property and assets  transferred to
the Acquiring  Fund at the Closing Date and shall not be separately  valued,  in
which case any such  distribution  that  remains  unpaid as of the Closing  Date
shall  be  included  in the  determination  of the  value of the  assets  of the
Acquired Fund acquired by the Acquiring Fund.

          1.3. The Acquired Fund will make  reasonable  efforts to discharge all
of its known  liabilities  and  obligations  prior to the  Valuation  Date.  The
Acquiring Fund shall assume all of the liabilities of the Acquired Fund, whether
accrued  or  contingent,  known  or  unknown,  existing  at the  Valuation  Date
(collectively, "Liabilities"). On or as soon as practicable prior to the Closing
Date, the Acquired Fund will declare and pay to its  shareholders  of record one
or more dividends  and/or other  distributions  so that it will have distributed
substantially  all (and in no event  less  than 98%) of its  investment  company
taxable income (computed without regard to any deduction for dividends paid) and
realized  net capital  gain,  if any,  for the current  taxable year through the
Closing Date.

          1.4.  Immediately  following the actions contemplated by paragraph 1.1
herein,  Hartford  HLS  Series  Fund II shall  take such  actions  necessary  to
complete the  liquidation  of the Acquired  Fund.  To complete the  liquidation,
Hartford  HLS  Series  Fund II,  on  behalf  of the  Acquired  Fund,  shall  (a)
distribute to the Acquired  Fund's  shareholders  of record with respect to each
class of its  shares as of the  Closing  as  defined  in  paragraph  3.1  herein
("Acquired  Fund  Shareholders"),  on a pro rata basis  within  the  class,  the
Acquiring Fund Shares of the  corresponding  class received by the Acquired Fund
pursuant  to  paragraph  1.1  herein,   and  (b)  completely   liquidate.   Such
distribution and liquidation will be accomplished, with respect to each class of
Acquired Fund shares, by the transfer of the Acquiring Fund Shares then credited
to the account of the Acquired Fund on the books of the  Acquiring  Fund to open
accounts on the share records of the Acquiring Fund in the names of the Acquired
Fund Shareholders.  The aggregate net asset value of Acquiring Fund Shares to be
so credited to the Acquired Fund Shareholders  shall, with respect to the class,
be equal to the  aggregate  net asset value of the  Acquired  Fund Shares of the
corresponding class owned by Acquired Fund Shareholders on the Closing Date. All
issued and outstanding  Acquired Fund Shares will  simultaneously be canceled on
the  books of the  Acquired  Fund,  although  shares  certificates  representing
interests in Acquired  Fund Shares will  thereafter  represent  interests in the
corresponding  class of  Acquiring  Fund  Shares  after  the  Closing  Date,  as
determined in accordance  with paragraph 2.3. The Acquiring Fund shall not issue
certificates  representing  the  Acquiring  Fund Shares in  connection  with the
Reorganization.

          1.5.  Ownership of Acquiring Fund Shares will be shown on the books of
the Acquiring Fund's Transfer Agent, as defined in paragraph 3.3 herein.

          1.6. Any reporting responsibility of the Acquired Fund, including, but
not limited to, the responsibility for filing regulatory  reports,  tax returns,
or other documents with the Securities and Exchange  Commission  ("Commission"),
any state securities commission, and any Federal, state or local tax authorities
or  any  other  relevant   regulatory   authority,   is  and  shall  remain  the
responsibility of the Acquired Fund.

2. VALUATION

          2.1.  The value of the Assets  shall be the value of such Assets as of
the close of business of the New York Stock  Exchange and after the  declaration
of any  dividends  on the  Closing  Date (such  time and date being  hereinafter
called the "Valuation Date"),  computed using the valuation procedures set forth
in the  then-current  prospectus  and statement of additional  information  with
respect to the Acquired Fund and valuation  procedures  established  by Hartford
HLS Series Fund II's Board of Directors.

                                      2


          2.2. The net asset value of each Acquiring Fund Share shall be the net
asset value per share computed with respect to the corresponding class as of the
Valuation Date, using the valuation procedures set forth in the Acquiring Fund's
then-current prospectus and statement of additional  information,  and valuation
procedures established by the Hartford Series Fund's Board of Directors.

          2.3. The number of the Acquiring  Fund Shares to be issued  (including
fractional  shares,  if any) in exchange for the Acquired Fund's Assets shall be
determined  by dividing the value of the net assets with respect to the Acquired
Fund  Shares,  determined  using the same  valuation  procedures  referred to in
paragraph  2.1  herein,  by the net asset  value of the  corresponding  class of
Acquiring Fund Shares, determined in accordance with paragraph 2.2 herein.

          2.4.  All  computations  of  value  shall  be made by  [Hartford  Life
Insurance  Company],  in its capacity as [Fund Accountant] for the Company,  and

portfolio  securities  represented by a certificate or other written  instrument
shall be presented by the  Custodian to those  persons at the Custodian who have
primary  responsibility for the safekeeping of the assets of the Acquiring Fund,
as the  Custodian  also serves as the custodian  for the  Acquiring  Fund.  Such

preceding the Closing Date, and such certificates and other written  instruments
shall be  transferred  and delivered by the Acquired Fund as of the Closing Date
for the account of the Acquiring  Fund duly endorsed in proper form for transfer

Closing.  The Secretary of the Companies  shall confirm that (a) the appropriate
number of  Acquiring  Fund Shares  have been  credited  to the  Acquired  Fund's

reporting of trading on such Exchange

                                        3

bankruptcy, insolvency, reorganization, moratorium and other laws relating to or
affecting creditors' rights and to general equity principles;

behalf of the Acquiring  Fund,  knows of no facts which might form the basis for
the  institution  of such  proceedings  and is not a party to or  subject to the
provisions of any order,  decree or judgment of any court or


                                        6


governmental  body which  materially and adversely  affects the Acquiring Fund's
business or its ability to consummate the transactions herein contemplated;

                  (g) The  Statement of Assets and  Liabilities,  Statements  of
Operations  and  Changes  in Net  Assets  and  Schedule  of  Investments  of the
Acquiring  Fund at  December  31,  2006 have been  audited by Ernst & Young LLP,
public accounting firm, who issued an unqualified opinion thereon;

                  (h) Since  December 31, 2006,  there has not been any material
adverse change in the Acquiring Fund's financial condition,  assets, liabilities
or business, other than changes occurring in the ordinary course of business, or
any incurrence by the Acquiring Fund of indebtedness  other than in the ordinary
course in accordance  with the Acquiring  Fund's  investment  restrictions.  For
purposes of this subparagraph (h), a decline in net asset value per share of the
Acquiring Fund Shares due to declines in market values of securities held by the
Acquiring Fund, the discharge of Acquiring Fund  liabilities,  or the redemption
of  Acquiring  Fund Shares by  shareholders  of the  Acquiring  Fund,  shall not
constitute a material adverse change;

                  (i) On the Closing  Date,  all Federal and other tax  returns,
dividend  reporting forms, and other  tax-related  reports of the Acquiring Fund
required by law to have been filed by such date (including any extensions) shall
have been  filed and are or will be correct in all  material  respects,  and all
Federal  and other  taxes  shown as due or  required  to be shown as due on said
returns and reports  shall have been paid or provision  shall have been made for
the payment  thereof,  and to the best knowledge of Hartford Series Fund no such
return is currently under audit and no assessment has been asserted with respect
to such returns;

                  (j) For each  taxable  year of its  operation  (including  the
taxable year that includes the Closing  Date),  the  Acquiring  Fund has met (or
will meet) the  requirements of Subchapter M of the Code for  qualification as a
regulated  investment company, has been eligible to (or will be eligible to) and
has computed (or will  compute) its Federal  income tax under Section 852 of the
Code;

                  (k) All issued and outstanding  Acquiring Fund Shares are, and
on the Closing Date will be, duly and validly issued and outstanding, fully paid
and  non-assessable  by Hartford  Series Fund and have been  offered and sold in
every  state,  territory  and the  District  of Columbia  in  compliance  in all
material respects with applicable registration  requirements of the 1933 Act and
other securities laws. The Acquiring Fund does not have outstanding any options,
warrants or other rights to subscribe for or purchase any Acquiring Fund Shares,
nor is there  outstanding  any  security  convertible  into any  Acquiring  Fund
Shares;

                  (l) The execution,  delivery and performance of this Agreement
and the  transactions  contemplated  herein,  have been duly  authorized  by all
necessary  action, if any, on the part of the Directors of Hartford Series Fund,
on behalf of the  Acquiring  Fund,  and this  Agreement  constitutes a valid and
binding  obligation of Hartford  Series Fund,  on behalf of the Acquiring  Fund,
enforceable  in  accordance  with its  terms,  subject,  as to  enforcement,  to
bankruptcy, insolvency, reorganization, moratorium and other laws relating to or
affecting creditors' rights and to general equity principles;

                  (m) The  Class IA  Acquiring  Fund  Shares  to be  issued  and
delivered  to  the  Acquired   Fund,  for  the  account  of  the  Acquired  Fund
Shareholders,  pursuant to the terms of this Agreement, will on the Closing Date
have been duly  authorized  and, when so issued and delivered,  will be duly and
validly issued Acquiring Fund Shares,  and will be fully paid and non-assessable
by the Acquiring Fund;

                  (n) The  information to be furnished by the Acquiring Fund for
use in the registration statements, proxy materials and other documents that may
be necessary in connection with the  transactions  contemplated  hereby shall be
accurate and complete in all material  respects and shall comply in all material
respects  with  Federal  securities  and other laws and  regulations  applicable
thereto; and


                                        7


                  (o) The Proxy  Statement  to be included  in the  Registration
Statement  REFERRED TO IN PARAGRAPH  5.5 HEREIN (and any amendment or supplement
thereto),  insofar as it relates to the Acquiring  Fund and the  Acquiring  Fund
Shares, will, from the effective date of the Registration  Statement through the
date of the meeting of  shareholders of the Acquired Fund  contemplated  therein
and on the Closing Date (i) not contain any untrue  statement of a material fact
or omit to state a material fact  required to be stated  therein or necessary to
make the  statements  therein,  in light of the  circumstances  under which such
statements were made, not materially  misleading,  provided,  however,  that the
representations  and  warranties  of this  subparagraph  (o)  shall not apply to
statements  in or  omissions  from  the  Proxy  Statement  and the  Registration
Statement  made in reliance upon and in  conformity  with  information  that was
furnished by the Acquired Fund for use therein,  and (ii) comply in all material
respects with the provisions of the 1933 Act, the 1934 Act, and the 1940 Act and
the rules and regulations thereunder.
