ITEM 5.           OTHER EVENTS.

A.       On October 10, 1996, the Company entered into a definitive agreement
(the "Purchase Agreement") to acquire certain portions of the group health and 
related life business (the "GBO Operations") of the Group Benefit Operations 
Division (the "GBO Division") of John Hancock Mutual Life Insurance Company 
("Hancock") for an aggregate purchase price of $86.7 million.

         The transaction is structured as the acquisition of the assets and
assumption of the liabilities of the GBO Division by the Company (or its
designated affiliate, which is contemplated to be UNICARE Life & Health
Insurance Company, a Delaware stock life insurance company ("UNICARE")) and the
purchase of the stock of certain subsidiaries of Hancock which are part of
Hancock's GBO Operations (including Cost Care, Inc.). The Purchase Agreement
provides for a purchase price adjustment based on a post-closing audit of a
balance sheet (the "Closing Balance Sheet") to be prepared reflecting all the
assets and liabilities acquired in the transaction. WellPoint will be required
to pay the amount of the excess of net assets acquired over the net liabilities
assumed to Hancock and Hancock will be required to pay to WellPoint the amount
of any excess of liabilities over net book value of the assets acquired. The
Closing Balance Sheet will be prepared in accordance with agreed-upon procedures
and policies which are outlined in a "Summary of Accounting Principles and
Procedures" attached hereto as an exhibit. Hancock has further agreed to not
engage in any business competitive with the health and disability insurance
business of the GBO Operations for a period of five years following closing 
of the transaction.

         At the closing of the acquisition (which is expected to occur in
January 1997), Hancock and UNICARE will enter into a Coinsurance Agreement
pursuant to which UNICARE will reinsure, on a 100% share coinsurance basis,
Hancock's reserves and liabilities, after reduction for third-party reinsurance,
with respect to currently existing GBO Operations policies and with respect to
additional GBO policies issued on behalf of UNICARE during a 24-month or 
30-month transition period (depending on the type of coverage) following the 
closing. Policies subject to such reinsurance include only those that are in 
effect at the closing date or, if they have lapsed prior to that time, only 
those which are included in reserves set forth on the Closing Balance Sheet. 
Hancock will issue transition GBO Operations policies on behalf of UNICARE 
for such 24-month or 30-month period while UNICARE obtains any necessary 
permits and form approvals to issue such policies in its own name.

         At the closing, UNICARE and Hancock will also enter into an Assumption
and Reinsurance Agreement which will provide for UNICARE to replace Hancock on
a 100% assumption reinsurance basis on the above-described coinsured policies at
such time as UNICARE has the licenses and permits and form approvals as are
necessary to
<PAGE>   3
reinsure the coinsurance policies and the insured parties have consented to such
assumption and reinsurance.

         A Limited License Agreement to be entered between UNICARE and Hancock
will entitle UNICARE to use the name "John Hancock" and related Hancock service
marks in connection with the marketing of insurance policies and administrative
services by UNICARE during the 30-month transition period. UNICARE and Hancock 
will also enter into an Administrative Services Agreement and a "Services 
Agreement" at the closing of the acquisition. The Administration Agreement 
provides that UNICARE will perform certain administration services with respect 
to the coinsurance policies, administrative services contracts and net 
contracts in order to facilitate the transition of the GBO Business from 
Hancock to WellPoint. Such services to be performed by UNICARE include, among 
other things, claims administration, policy and contract administration, fee 
administration and certain financial, statistical and tax services relating to 
the contracts being administered. The Service Agreement provides for computer 
and other support services to be provided by Hancock to UNICARE during the 
two-year period immediately following the closing of the transaction.


B.      On October 9, 1996, the Superior Court of the State of California for
Los Angeles County approved the settlement (the "Settlement") of four
substantially identical actions that had been filed against WellPoint, certain
of WellPoint's officers and directors, and Blue Cross of California in March
and April of 1995. The complaints in Gollomp and Gober, et al. v. Schaeffer,
Williams, Rich, Weinberg, et al.; Greenberg, et al. v. Schaeffer, Williams,
Rich, Weinberg, et al.; Freed, et al. v. Schaeffer, Williams, Rich, Weinberg, et
al.; and Kaiser v. WellPoint Health Networks Inc., Blue Cross of California,
et al., alleged that the defendants breached fiduciary duties to WellPoint's 
public stockholders by, among other things, pursuing a business combination 
with Health Systems International and purportedly rejecting certain other 
proposals due consideration.

        All class action claims asserted on behalf of WellPoint's public
stockholders were dismissed on August 10, 1995, leaving only claims asserted
derivatively on behalf of WellPoint. On October 9, 1996, the Settlement of the
remaining claims asserted in the actions was approved by the Court as fair,
reasonable and adequate to WellPoint and its stockholders after notice to
stockholders and the opportunity to object to its terms. On October 21, 1996
the Court issued an order (i) extending the period for objections to the 
Settlement to be filed until November 8, 1996, and (ii) getting a status 
conference regarding the proposed judgment for November 26, 1996.

        All of the Settlement documentation is on file with the Los Angeles
County Superior Court. The principal terms of the Settlement require:

                1. Certain continuing obligations regarding the structure and
                   operation of future independent committees of the Company 
                   that may be formed to investigate or evaluate potential 
                   mergers, acquisitions, financial restructurings or exchange 
                   transactions, as described below.
        
                2. Certain limitations on the Company's ability to make "change
                   in control" or "golden parachute" payments to officers or 
                   directors.

                3. The Company's Board of Directors must consider and adopt a 
                   policy and/or recommendations regarding payment of 
                   dividends to its shareholders on an annual basis.

                4. The payment $1,850,000 in attorneys' fees and costs to
                   plaintiffs' counsel.
<PAGE>   4

        The obligations summarized in items 1-3 above will continue in effect
for a minimum of five (5) years. Under the terms of the Settlement, WellPoint,
Blue Cross of California and the individual defendants do not admit, and
expressly deny, all claims and liability asserted against them. The Settlement
also includes a release of all claims alleged in the actions.

        The following is a summary of provisions of the Settlement relating to
future independent committees of the Company that may be formed to investigate 
or evaluate mergers, acquisitions, financial restructurings or exchange 
transactions.

                (a) There will be no prior familial, professional or business
relationship (other than service on the Board of Directors of WellPoint or any
of its predecessor boards) between the Company and its executive officers, on
the one hand, and any members of the committee and the committee's advisors
(other than through an independent committee), on the other. For purposes of
this subparagraph, (i) a prior relationship with one of the committee's
advisors will be disqualifying only to the extent that it existed within two
years prior to formation of the independent committee, and (ii) employment as
an advisor to a prior independent committee of the Company will not preclude
employment as an advisor to a subsequent independent committee of the Company.

                (b) The independent committee (and not the Company or its
executive officers) will direct the activities of the committee's advisors.

                (c) Meetings of the independent committee will be chaired by a
member of the committee (and not by any executive of the Company).

                (d) No executive officer of the Company will serve on the
independent committee or as secretary or legal counsel to the committee. The
role of the Company's executive officers in the activities of the committee will
be limited to providing information or performing specified assignments at the
request and direction of the committee.

                (e) If any executive officer of the Company attends a meeting
of the independent committee, the purpose of such attendance will be stated in
the committee minutes.

                (f) Any written materials created for or on behalf of the
independent committee will only be disclosed or released to executive officers
of the Company upon a resolution and affirmative vote of the committee, unless
the matter for which the committee was created is concluded.

                (g) Any due diligence investigation supervised by or at the
behest of the committee in connection with a sale or potential sale undertaken
of the Company or any material portion thereof will be directed by the
committee. A log or list of the date, purpose and type of due diligence
information disseminated or received will be kept.

                (h) One or more members of the independent committee will
participate in or oversee any negotiations that may result in a merger,
acquisition, financial restructuring or exchange transaction of or by the
Company.

                         REPORT OF INDEPENDENT AUDITORS

To the Board of Directors
John Hancock Mutual Life Insurance Company

We have audited the accompanying combined statements of assets and liabilities
of the Group Benefits Operations (GBO) of John Hancock Mutual Life Insurance
Company and subsidiaries (the Company) as of December 31, 1995 and 1994, and
the related combined statements of operations and changes in net asset balance
and cash flows for the years then ended. These combined financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the combined financial statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

The combined financial statements have been prepared in conformity with
accounting principles that are generally accepted for stock life insurance
companies. These principles, which are described in Note 1, differ from
statutory accounting practices, which the Company uses to prepare its
general-purpose financial statements.

In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the combined financial position of the Group
Benefits Operations of John Hancock Mutual Life Insurance Company and
subsidiaries at December 31, 1995 and 1994 and the combined results of their
operations and their cash flows for the years then ended in conformity with
accounting principles that are generally accepted for stock life insurance
companies. 

As discussed in Note 1 to the financial statements, in 1994, the GBO changed
its method of accounting for postemployment benefits.

NOTES TO COMBINED FINANCIAL STATEMENTS

THE GROUP BENEFITS OPERATIONS OF JOHN HANCOCK MUTUAL LIFE INSURANCE
COMPANY AND SUBSIDIARIES

NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation
- ---------------------

The accompanying combined financial statements include certain operations of
the group life and accident and health insurance business of John Hancock
Mutual Life Insurance Company (John Hancock) and Cost Care, Inc., Hancock
Association Services Group and Tri-State, Inc. (the Group Benefits Operations
or GBO). Cost Care, Inc., Hancock Association Services Group and Tri-State, Inc.
are wholly owned, indirect subsidiaries of John Hancock. 

The GBO business is expected to be acquired pursuant to an agreement being
negotiated between John Hancock and WellPoint Health Networks, Inc. (see Note
7). GBO has transactions with affiliated companies, the terms and conditions of
which are determined by GBO and the members of the affiliated group. GBO
operating costs and expenses consist of direct costs, allocated costs, and
allocated corporate overhead. Accordingly, these financial statements might not
be indicative of the financial position and results of operations that would
have occurred had GBO operated as a nonaffiliated entity. 

The combined financial statements of GBO have been prepared in conformity with
generally accepted accounting principles (GAAP), applied on a consistent basis,
for stock life insurance companies (stock life basis), which vary from
statutory accounting practices as prescribed or permitted by the Commonwealth
of Massachusetts Division of Insurance and the National Association of
Insurance Commissioners. 

All significant intercompany accounts and transactions have been eliminated.

The preparation of financial statements in conformity with GAAP requires
management to make estimates and assumptions that affect amounts reported in
the financial statements and accompanying notes. Such estimates and assumptions
could change in the future as more information becomes known, which could
impact the amounts reported and disclosed herein. 

Operations
- ----------

GBO is not a legal entity but conducts group life and accident and health
insurance business through John Hancock and its subsidiaries. GBO principally
offers group life and accident and health insurance products and administrative
services to its group customers in all fifty states, the District of Columbia
and Puerto Rico. 

For fully insured contracts, the policyholder elects either prospectively
pooled experience rated insurance or experience rated refund eligible
insurance. Further, the policyholder is offered fully funded or partially
funded payment options. The partially funded Minimum Premium Contract
incorporates similar insurance risks to GBO but with employer self-funding of
claims, introducing credit risk relating to employer funding. Administrative
services contracts are provided to 


                                                                            5

self-insured plans whereby GBO provides the claims management and processing
service, and in many cases excess or stop-loss insurance. GBO also provides a
range of health care cost management services including pre-admission review
for in-patient hospital admission and preferred provider management to
insurance underwriters and private businesses for a predetermined, periodic fee
and on a fee-for-service basis.

GBO has dedicated sales, underwriting, actuarial, product development, premium
and claims operations, and systems support. Products are distributed through
group representatives, who are John Hancock employees, or through 
intermediaries.

Pending Accounting Standards
- ----------------------------

In April 1993, the Financial Accounting Standard Board (FASB) issued
Interpretation No. 40, "Applicability of Generally Accepted Accounting
Principles to Mutual Life Insurance and Other Enterprises" (Interpretation).
The Interpretation, as amended, is effective for 1996 annual financial
statements and thereafter, and will require life insurance companies to adopt
all applicable authoritative GAAP pronouncements in any general-purpose
financial statements that they may issue and describe as being in accordance
with GAAP.

In January 1995, in response to Interpretation 40, the FASB issued Statement of
Financial Accounting Standards (SFAS) No. 120, "Accounting and Reporting by
Mutual Life Insurance Enterprises and by Insurance Enterprises for Certain
Long-Duration Participating Contracts." This Statement effectively establishes
generally accepted accounting principles, which are different from statutory
accounting principles, for mutual life insurance companies. Through December
31, 1995, statutory accounting practices were considered to be generally
accepted accounting principles for mutual life insurance companies.

SFAS No. 120 is effective for financial statements issued for fiscal years
beginning after December 15, 1995. Because the accompanying financial
statements of GBO have been prepared in conformity with GAAP for stock life
insurance companies, the adoption of the new pronouncements that define GAAP
for mutual life insurance companies is not expected to have a material effect
on GBO's results of operations or statements of assets and liabilities.

In March 1995, the FASB issued SFAS No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed Of." This Statement
requires that long-lived assets and certain identifiable intangibles to be held
and used by an entity be reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable. In those cases where it is determined that the carrying amount is
not recoverable, an impairment loss is recognized (the difference between the
cost and fair value of the asset). The Statement also requires long-lived assets
to be disposed of (e.g., real estate held for sale) to be carried at the lower
of cost or fair value less cost to sell and does not allow such assets to be
depreciated. This Statement is effective for 1996 financial statements. The
adoption of SFAS No. 121 is not expected to have a material effect on GBO's
results of operations or statements of assets and liabilities.


                                                                               6

COMPANY AND SUBSIDIARIES

NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- CONTINUED

SFAS No. 125, "Accounting for Transfers and Servicing of Financial Assets and
Extinguishments of Liabilities," was issued in June 1996, and is not expected to
have a material effect on GBO's results of operations or statements of assets
and liabilities.

Postemployment Benefits
- -----------------------

Effective January 1, 1994, GBO adopted SFAS No. 112, "Employers' Accounting for
Postemployment Benefits," and established a liability for the costs and
obligations of benefits such as severance, disability, life insurance, and
health care to be paid to inactive or former employees. A transition obligation
of $2,910 thousand, net of taxes of $1,567 thousand, was recognized upon
adoption.

Receivable from John Hancock
- ----------------------------

GBO is not a separate legal entity and does not have specifically identifiable
cash or investments. The receivable from John Hancock included in the
accompanying combined statements of assets and liabilities represents the
difference between GBO operating business assets and liabilities. It does not
bear a stated rate of interest. However, investment income is allocated to GBO
based on the portfolio investment income of the underlying general account
assets of John Hancock that support GBO's business.

Revenue Recognition
- -------------------

Insurance premiums on fully insured and partially funded contracts are earned
on a pro-rata basis over the period in which services are obligated to be
provided. The portion of premiums not earned at the end of the period is
recorded as unearned insurance premiums.

Administrative service fees are earned on a pro-rata basis as the services are
performed.

Dividends
- ---------

Dividends for eligible contracts are based on premiums received in excess of
claims and expenses incurred. The dividend liability for completed policy years
is established based on policy year experience, while dividends for incomplete
policy years are established based on experience through the financial

Income Taxes
- ------------

John Hancock and certain of its affiliates, including the GBO operations, file
a consolidated federal income tax return. However, because GBO is not a
separate legal entity, a formal tax allocation agreement between John Hancock
and GBO has not been executed. For purposes of these financial statements, GBO
has been treated as a separate business of a mutual life insurance company for
the determination of the tax provision. Accordingly, income tax benefit is
allocated to GBO at 35% and is settled currently through the receivable from
John Hancock. The gross asset and liability balances relating to the future tax
consequences of temporary differences between the financial reporting and tax
basis of assets and liabilities are recorded at the John Hancock

                                                                               7

consolidated level. An equity tax, applicable to mutual life insurance
companies, has not been included in the provision. 

Intangible Assets 
- -----------------

Intangible assets, which include noncompete agreements, long-term employment
contracts, capitalized software and other intangibles, are amortized using the
straight-line method over their estimated useful lives, which range from two to
forty years. Accumulated amortization was $18,253 thousand and $13,643 thousand
at December 31, 1995 and 1994, respectively. 

Property, Equipment and Leasehold Improvements 
- ----------------------------------------------

Property and equipment, principally composed of furniture and equipment, are
reported at depreciated cost. Depreciation is computed using the straight-line
method based upon the estimated useful lives of the assets. Leasehold
improvements are depreciated over the shorter of the lease term or the
estimated useful life. 

Future Policy Benefits and Expenses 
- -----------------------------------

Future policy benefits for group life and accident and health contracts have
been computed using interest rates ranging from 2.5% to 8.42%, and mortality,
morbidity, and withdrawal assumptions based on GBO's experience and industry
standards. 

Liabilities for unpaid claims and claim expenses include estimates of payments
to be made on reported life and accident and health insurance claims and
estimates of incurred but not reported claims based on historical claims
development patterns. 

Estimates of future policy benefit reserves, claim reserves and expenses are
reviewed continually and adjusted as necessary; such adjustments are reflected
in current operations. Although considerable variability is inherent in such
estimates, management believes that future policy benefit reserves, claim and
expense reserves are adequate. 

Payable to Affiliate 
- --------------------

Payable to affiliate represents the amount due to John Hancock principally as a
result of intercompany expense allocations. 

Reinsurance 
- -----------

All assets and liabilities related to reinsurance ceded contracts are reported
on a gross basis in the accompanying statements of assets and liabilities. The
accompanying statements of operations reflect premiums, benefits and expenses
net of reinsurance ceded. 

GBO assumes and cedes reinsurance and participates in various pools and
associations. The portion of risks that exceeds GBO's retention limits is
reinsured with other insurers. GBO also obtains other reinsurance coverages
with retentions and limits that management believes are appropriate for the
circumstances. Those reinsurance agreements provide for greater diversification
of business, allow management to control exposure to potential losses arising
from 

                                                                            8

large risks and provide additional capacity for growth. Amounts recoverable from
reinsurers are estimated in a manner consistent with the future policy benefit
and claim liabilities associated with the reinsured policies.

Reinsurance premiums, commissions, expense reimbursements, benefits and reserves
related to reinsured business are accounted for on bases consistent with those
used in accounting for original policies issued and the terms of the reinsurance
contracts.

Restructuring Charges
- ---------------------

In 1994, the GBO recorded a $34,722 thousand restructuring charge in accordance
with its plans to reduce its cost structure and consolidate operations. This
charge included accruals for severance and related benefits for staff
reductions, property lease terminations, and the write-off of certain assets.
The restructuring liability is settled through the receivable from John Hancock.
The remaining balance of the restructuring liability at December 31, 1995 and
1994 was $7,915 thousand and $23,362 thousand, respectively. The majority of the
remaining balance relates to deferred benefits for terminated employees and
leases.

NOTE 2 -- REINSURANCE

The effect of reinsurance on premiums written and earned was as follows:

NOTE 2 - REINSURANCE - CONTINUED

Reinsurance ceded contracts do not relieve the GBO from its obligations to
contractholders. The GBO remains liable to its contractholders for the portion
reinsured to the extent that any reinsurer does not meet its obligations for
reinsurance ceded to it under the reinsurance agreements. Failure of the
reinsurers to honor their obligations could result in losses to GBO;
consequently, estimates are established for amounts deemed or estimated to be
uncollectible. To minimize its exposure to significant losses from reinsurance
insolvencies, GBO evaluates the financial condition of its reinsurers and
monitors concentration of credit risk.

NOTE 3 - LIABILITY FOR UNPAID CLAIMS

Activity in the liability for unpaid accident and health claims and loss
adjustment expenses is as follows:

NOTE 5 -- RELATED PARTY TRANSACTIONS

The various related party transactions between John Hancock and GBO are
summarized below.

OPERATING EXPENSES: John Hancock provides GBO with personnel, property and
facilities including certain services such as investment management, legal,
financial and administrative support. GBO is charged for these services
utilizing various methods of expense allocation which are primarily based on
time incurred, ratios of direct and indirect expenses, square footage occupied,
or allocated in pro rata relationship to other business units of John Hancock.
Management believes the methods used to allocate such costs are reasonable.
Operating expenses allocated to GBO amounted to $189,883 thousand and $193,060
thousand in 1995 and 1994, respectively.

INVESTMENT INCOME AND RECEIVABLE FROM JOHN HANCOCK: GBO is not a separate legal
entity and does not have specifically identifiable cash or investments. The
receivable from John Hancock included in the accompanying combined statements
of assets and liabilities represents the difference between GBO operating
business assets and liabilities. The fair value of the receivable from John
Hancock approximates its carrying value at December 31, 1995 and 1994.

GBO is allocated investment income based on the portfolio income of the
underlying general account assets of the John Hancock that support GBO's
business. Investment income allocated to GBO was $35,374 thousand and $41,040
thousand in 1995 and 1994, respectively.

BENEFIT PLANS: Eligible employees of John Hancock participate in various types
of pension plans sponsored by John Hancock which include defined benefit,
defined contribution and nonqualified

                                                                            11

plans. Pension benefits under the defined benefit plans are based on years of
service and average compensation, generally during the five years prior to
retirement. John Hancock's funding policy for qualified defined benefit plans
is to contribute annually an amount in excess of the minimum annual
contribution required under the Employee Retirement Income Security Act
(ERISA). This amount is limited by the maximum amount that can be deducted for
federal income tax purposes. Plan assets consist principally of listed equity
securities, corporate obligations and U.S. government securities. GBO is
allocated its proportionate share of expense based on John Hancock's
intercompany expense allocation methodology. John Hancock also has various
defined contribution plans, nonqualified plans and additional compensation
plans covering its employees and agents. GBO is allocated a share of the
expenses related to the plans pursuant to John Hancock's intercompany expense
allocation methodology. John Hancock also provides certain life and accident
and health insurance benefit plans covering most of its retired employees and
general agency personnel. GBO is allocated its proportionate share of these
expenses. 

Total benefit plan expense allocated to GBO was $14,186 thousand and $14,515
thousand for 1995 and 1994, respectively.

GBO has issued certain group life and accident and health insurance contracts
to cover employees of John Hancock. Premiums, benefits (including the provision
for future benefits), and reserves included in the combined statements of
operations and changes in net asset balance and combined statements of assets
and liabilities associated with the coverage approximates $23,978 thousand,
$24,154 thousand, and $53,706 thousand, in 1995, respectively. The
corresponding amounts in 1994 were $18,903 thousand, $19,487 thousand, and
$59,270 thousand, respectively.

NOTE 6--CONTINGENCIES

In the normal course of its business operations, GBO is involved in litigation
from time to time with claimants, beneficiaries and others, and a number of
litigation matters were pending as of December 31, 1995. It is the opinion of
management, after consultation with counsel, that the ultimate liability
with respect to these claims, if any, will not materially impact the financial
condition of GBO.

NOTE 7--SUBSEQUENT EVENTS

John Hancock and WellPoint Health Networks, Inc. are negotiating an agreement
for the sale of GBO to WellPoint Health Networks, Inc. The closing of the sale
is contingent upon state insurance department and other regulatory approvals.
The transaction is expected to close in the fourth quarter of 1996.

                     --------------------------------------

EVENT (UNAUDITED) SUBSEQUENT TO DATE OF INDEPENDENT AUDITORS' REPORT

On October 10, 1996, John Hancock and WellPoint Health Networks, Inc. signed a
definitive agreement for the sale of GBO to WellPoint Health Networks, Inc.
Under the terms of the definitive agreement, the sale is currently scheduled to
close in January 1997.

NOTES TO COMBINED FINANCIAL STATEMENTS (UNAUDITED)

THE GROUP BENEFITS OPERATIONS OF JOHN HANCOCK MUTUAL LIFE INSURANCE
COMPANY AND SUBSIDIARIES


NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION
- ---------------------

The accompanying unaudited combined financial statements include certain
operations of the group life and accident and health insurance business of John
Hancock Mutual Life Insurance Company (John Hancock) and Cost Care, Inc.,
Hancock Association Services Group and Tri-State, Inc. (the Group Benefits
Operations or GBO). Cost Care, Inc., Hancock Association Services Group and
Tri-State, Inc. are wholly owned, indirect subsidiaries of John Hancock.

The GBO business is expected to be acquired pursuant to an agreement between
John Hancock and WellPoint Health Networks, Inc. (see Note 3). GBO has
transactions with affiliated companies, the terms and conditions of which are
determined by GBO and the members of the affiliated group. GBO operating costs
and expenses consist of direct costs, allocated costs, and allocated corporate
overhead. Accordingly, these financial statements might not be indicative of
the financial position and results of operations that would have occurred had
GBO operated as a nonaffiliated entity.

The accompanying unaudited combined financial statements of GBO have been
prepared in accordance with generally accepted accounting principles (GAAP) for
interim financial information, applied on a consistent basis, for stock life
insurance companies (stock life basis); which vary from statutory accounting
practices as prescribed or permitted by the Commonwealth of Massachusetts
Division of Insurance and the National Association of Insurance Commissioners.
Accordingly, they do not include all of the information and footnotes required
by generally accepted accounting principles for complete financial statements.
In the opinion of management, all adjustments (consisting of normal recurring
accruals) considered necessary for a fair presentation have been included.
Operating results for the six-month period ended June 30, 1996 are not
necessarily indicative of the results that may be expected for the year ended
December 31, 1996. For further information, refer to the combined financial
statements and footnotes for the years ended December 31, 1995 and 1994.


Statement of Financial Accounting Standards (SFAS) No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of"
- -----------------------------------------------------------------------------

In March 1995, the FASB issued SFAS No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed Of." This Statement
requires that long-lived assets and certain identifiable intangibles to be held 
and used by an entity be reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable. In those cases where it is determined that the carrying amount is
not recoverable, an impairment loss is recognized (the difference between the
cost and fair value of the asset). The Statement also requires long-lived
assets to be disposed of (e.g., real estate held for sale) to be carried at
the lower of cost or fair value less cost to sell and does not allow such
assets to be depreciated. This Statement is effective for 1996 financial
statements. The adoption of SFAS No. 121 did not have a material effect on
GBO's results of operations or statement of assets and liabilities.


                                                                           4

COMPANY AND SUBSIDIARIES


NOTE 2--CONTINGENCIES

In the normal course of its business operations, GBO is involved in litigation
from time to time with claimants, beneficiaries and others, and a number of
litigation matters were pending as of June 30, 1996. It is the opinion of
management, after consultation with counsel, that the ultimate liability with
respect to these claims, if any, will not materially impact the financial
condition of GBO.


NOTE 3--SUBSEQUENT EVENT

On October 10, 1996, John Hancock and WellPoint Health Networks, Inc. signed a
definitive agreement for the sale of GBO to WellPoint Health Networks Inc.
Under the terms of the definitive agreement, the sale is currently scheduled to
close in January 1997.

                           will, as provided in the Coinsurance Agreement and/or
                           the Assumption Reinsurance Agreement, assume
                           responsibility for claims and certain liabilities on
                           Existing GBO Policies.

                           (ii) Seller and Buyer or Unicare shall execute and
                  deliver an assignment and assumption agreement with respect to
                  the GBO Division Liabilities, which agreement shall provide
                  that Seller shall assign and transfer to Buyer or Unicare, and
                  Buyer or Unicare shall absolutely and irrevocably assume
                  without further liability or recourse to Seller (other than as
                  provided for in the Transaction Documents), and thereafter to
                  be solely liable for and pay, perform and discharge when due,
                  the GBO Division Liabilities.

                           (iii) Seller shall cause JHSI to transfer to Buyer
                  the certificates representing the CCI Shares, the TriState
                  Shares and the HASG Shares duly endorsed for transfer or
                  accompanied by stock powers in favor of Buyer.

                           (vii) Seller and Unicare will execute and deliver the
                  Administration Agreement.

                           (viii) Seller and Unicare will execute and deliver
                  the Service Agreement.

                           (ix) Seller and Unicare will execute and deliver the
                  Lease Agreements with respect to the Seller's Facilities
                  located in Boston, Massachusetts and Dearborn, Michigan, and
                  will execute and, subject to the terms of Section 1.2(b),
                  deliver Lease Assignments with respect to each of the GBO
                  Division Leases.

                  The sale, assignment, transfer, license, sublicense and
conveyance to Buyer (or Unicare as appropriate) of the GBO Subsidiaries Shares
and the GBO Division Assets (including without limitation the GBO Intellectual
Property of Seller), and the assumption of the GBO Division Liabilities, as
herein provided, shall be effected by appropriate deeds, bills of sale, stock
transfer powers or endorsements, assignments, license agreements, sublicense
agreements and assumption agreements on the part of the Buyer or Unicare, as
appropriate, drafts, checks and other instruments of transfer, conveyance and
assumption in form reasonably acceptable to Buyer or Unicare, as appropriate,
and Seller (the "GBO Conveyancing Documents").

                  The assignment and transfer of the GBO Included Assets shall
consist of (x) those GBO Division Assets required to be transferred pursuant to
the Coinsurance Agreement and (y) all remaining GBO Division Assets and the GBO
Subsidiaries Shares (by which the GBO Included Assets owned by the GBO
Subsidiaries are transferred) which shall be transferred pursuant to this
Agreement. Such assignment and transfer of the GBO Included Liabilities shall
consist of (i) those GBO Division Liabilities required to be assigned and
transferred pursuant to the Coinsurance Agreement and (ii) all remaining GBO
Division Liabilities, and the GBO Division Liabilities owed by the GBO
Subsidiaries which shall be assigned and transferred (either directly or by
transfer of the GBO Subsidiary Shares) pursuant to this Agreement.

                  (b) In full consideration of the sale, assignment, transfer
and conveyance to Buyer (or Unicare, as the case may be) of the GBO Included
Business, including the GBO Subsidiaries Shares, Buyer shall pay to Seller an
amount equal to $86,700,000 (the "Purchase Price"). At the Effective Time, the
Purchase Price shall be paid by Buyer to Seller by a wire transfer of
immediately available funds to such account as Seller shall designate in writing
to Buyer.

                  Section 1.2  Transfers Requiring Consent.

                  (a) At or prior to the Closing, Seller, with Buyer's
cooperation and assistance, shall obtain all approvals, consents or waivers
necessary to assign to Buyer or Unicare the GBO Division Contracts specified on
Schedule 11.5. Seller shall use reasonable commercial efforts to terminate
without cost effective after the Effective Time any vendor contract designated
by Buyer to the extent permitted by the terms of such vendor contract.

                  (b) With respect to the GBO Division Leases and GBO Division
Contracts (other than GBO Division Contracts provided for in Sections 1.3, 5.12
and 8.8) for which consent is not obtained, Seller, instead of obtaining any
approval, consent or waiver necessary to sell, assign, transfer, sublease or
otherwise convey to Buyer such GBO Division Leases and GBO Division Contracts,
shall take all steps necessary to confer upon Buyer, or otherwise obtain for
Buyer, the benefits of such GBO Division Leases and GBO Division Contracts at no
cost or expense to Buyer other than those costs and 


                                       4
<PAGE>   11
expenses that would otherwise be payable by Buyer (i) in the case of such GBO
Division Lease, had the applicable Lease Assignment in the form requested been
executed by the landlord thereunder, or (ii) in the case of such GBO Division
Contract, had such approval, consent or waiver been executed by the other party
thereto. If any approval, consent or waiver referred to in Section 1.2(a) above
with respect to any such GBO Division Lease or GBO Division Contract has not
been obtained by Seller, as of Closing, Seller shall, following the Closing and
with Buyer's cooperation, continue to use commercially reasonable efforts to
obtain such approval, consent or waiver; provided, however, that Seller shall
not be required to pay or incur any cost or expense to any counter-party to a
lease or contract to obtain such counter-parties' consent which Seller is not
otherwise required to pay or incur in accordance with the terms of the
applicable GBO Division Lease or GBO Material Contract. Until such time as
Seller has obtained any necessary approval, consent or waiver, Seller shall take
all steps necessary to confer all benefits of such GBO Division Leases and GBO
Division Contracts on Buyer until the earliest to occur of (i) such time as all
such approvals, consents or waivers are obtained or (ii) the expiration of the
applicable term of the GBO Division Lease or GBO Division Contract, as the case
may be. During the above time period with respect to any GBO Division Lease and
GBO Division Contract for which such approval, consent or waiver has not been
obtained, Seller shall authorize Buyer (A) to enforce, to the extent permitted
by law and at Buyer's expense, any and all rights of Seller arising from such
GBO Division Lease or GBO Division Contract against any other party or parties
thereto in Seller's name and on behalf of Seller and (B) to amend or terminate,
to the extent permitted by law and the terms of the applicable GBO Division
Lease or GBO Division Contract and at Buyer's expense, any such GBO Division
Lease or GBO Division Contract in Seller's name and on behalf of Seller with
Seller's consent for any such amendment, which will not be unreasonably
withheld, provided, however, that consent is not required for any amendment made
by Buyer that does not increase the liability of Seller under the applicable GBO
Division Lease or GBO Division Contract. If the benefits of any GBO Division
Lease or any GBO Division Contract for which such approvals, consents and
waivers have not been obtained are not able to be conferred on Buyer by Seller,
and (i) in the case of GBO Division Leases, if Buyer has to vacate the premises
thereunder prior to the end of the then current term under such GBO Division
Lease, or is required to pay additional amounts to remain in the tenancy, Seller
will reimburse Buyer or otherwise make Buyer whole for any such additional
amounts or for any out-of-pocket costs and expenses incurred by Buyer in moving
the GBO Business conducted on such premises to a new leased location in the
vicinity of such premises and for any increase in rent or other lease costs or
payments incurred by Buyer above the amount of rent or other cost Buyer would
otherwise be required to pay under such GBO Division Lease during the remainder
of the then current term under such GBO Division Lease, and (ii) with respect to
GBO Division Contracts, if Buyer has to replace any GBO Division Contract with a
new third party contract in order to enable Buyer to operate the GBO Business,
Seller will reimburse Buyer or otherwise make Buyer whole for any increase in
costs or expenses to Buyer in procuring from such third party the same or
similar services above the costs or expenses Buyer would otherwise be required
to pay under such GBO Division Contract during the remainder of the then current
term under such GBO Division Contract or for such lesser period during which the
third party to such GBO Division Contract would have been otherwise required to
render the services thereunder to Seller had not the transactions contemplated
by this Agreement taken place.

                  Section 1.3  ASO Contracts.

                  (a) At or prior to the Closing, Seller, with Buyer's
cooperation and assistance, shall use commercially reasonable efforts to obtain
all approvals, consents or waivers necessary to the sale, assignment and
transfer to Buyer of each of the ASO Contracts previously designated by Buyer
after consultation with Seller and in accordance with the transition plan
developed jointly by Buyer and Seller. Except as provided herein, Seller shall
not be required to pay or incur any cost or expense to obtain any third-party
approval, consent or waiver which Seller is not otherwise required to pay or
incur in 


                                       5
<PAGE>   12
accordance with the terms of the applicable ASO Contract. Seller and
Buyer shall each pay their respective out-of-pocket costs and expenses in
connection with the foregoing, including, without limitation, travel costs,
salaries and attorneys' fees. Notwithstanding the foregoing, the parties have
agreed that the obtaining of such approvals, consents and waivers is not a
condition to Closing, and in each case where consent is not obtained prior to
Closing subsection (b) below shall govern.

                  (b) Following the Closing, Buyer and Seller shall use good
faith efforts to obtain approvals, consents or waivers with respect to each ASO
Contract for which such approval, consent or waiver is necessary for the sale,
assignment and transfer of each of such ASO Contract to Buyer which has not been
obtained as of the Closing, until the earliest to occur of (i) the second
renewal or anniversary date of such ASO Contract occurring after the Closing
Date (it being understood that anniversary dates shall occur annually on the day
immediately following the expiration of the then-current Period (as defined in
the applicable ASO Contract)), (ii) such time as such approval, consent or
waiver is obtained, (iii) the date of termination by Buyer of such ASO Contract
in Seller's name as permitted under the provisions of such ASO Contract under
the authority to be granted pursuant to clause (C) of the immediately succeeding
sentence and (iv) the date Buyer or any Affiliate of the Buyer has entered into
a Contract with the counterparty to such ASO Contract providing for services
similar to those provided under such ASO Contract (with respect to each such ASO
Contract, its "Continuation Period"). During the Continuation Period with
respect to each such ASO Contract, Seller shall: (A) at Seller's expense,
transfer to Buyer an amount equal to all revenues and fees received by Seller or
its agents or Affiliates with respect to such ASO Contract; (B) authorize Buyer
through subcontract or delegation of duties at Buyer's expense, to perform all
obligations of Seller under, and enforce any and all rights of Seller arising
from such ASO Contract against any party or parties thereto in Seller's name and
on behalf of Seller (including bringing legal action in the name of Seller) to
the extent permitted by law and the terms of the applicable ASO Contract; and
(C) authorize Buyer at Buyer's expense, to amend or terminate any such ASO
Contract in Seller's name and on behalf of Seller, to the extent permitted by
law and the terms of the applicable ASO Contract, provided that no amendment
shall be effected pursuant to this clause which would reflect a substantial
deviation from the prevailing industry standards without Seller's consent, which
consent shall not be unreasonably withheld and shall be deemed given with
respect to any amendment if Seller has not given written notice to the contrary
within ten (10) days of receiving written notice of the proposal therefor.
During the Continuation Period with respect to each ASO Contract, Buyer shall,
at its own expense (except for expenses incurred by Seller in carrying out the
immediately preceding sentence), be solely responsible for the performance of
Seller's obligations under such ASO Contract, and Buyer shall on demand
indemnify, defend and hold harmless Seller and its Affiliates, and their
respective directors, officers and employees from and against any and all
demands, actions, proceedings, costs and Liabilities (including, without
limitation, the costs and expenses of defending any and all actions, suits,
proceedings, demands, assessments, judgments, settlements and compromises and
attorneys' fees in connection therewith), paid or incurred, resulting from,
arising out of or relating to Buyer's performance or non-performance thereunder
during the Continuation Period or failure to provide timely notice of
termination or cancellation pursuant to the penultimate sentence in this Section
1.3(b). Seller shall on demand indemnify, defend and hold harmless Buyer and its
Affiliates, and their respective directors, officers and employees, from and
against any and all demands, actions, proceedings, costs and Liabilities
(including, without limitation, the costs and expenses of defending any and all
actions, suits, proceedings, demands, assessments, judgments, settlements and
compromises and attorneys' fees in connection therewith), paid or incurred,
resulting from, arising out of or relating to Seller's failure to obtain, prior
to Closing, any approval, consent or waiver for the assignment and transfer of
any ASO Contract to Buyer; provided, however, that Seller shall not be obligated
to indemnify Buyer for any of Buyer's damages from its loss of profits,
revenues, or business opportunities resulting from, arising out of or relating
to any ASO Contract. The Liability of Seller or Buyer pursuant to this Section
1.3 shall not be subject to the threshold articulated in Article XIV, but shall
be measured from the first dollar. 


                                       6
<PAGE>   13
Buyer shall, on behalf of Seller and itself, to the extent permitted by law and
the terms of the applicable ASO Contract, send appropriate and timely notices,
advance copies of which shall have been provided to Seller by Buyer or Unicare,
to counterparties of ASO Contracts so that all ASO Contracts for which such
approvals, consents or waivers have not been obtained and which have not been
terminated or cancelled shall be cancelled or terminated effective as of the
second renewal or anniversary date thereof occurring after the Closing Date. As
of such second renewal or anniversary date, Seller shall be relieved of any
further obligation accruing after such date under this Section 1.3(b).

                  Section 1.4 Closing. The closing of the sale, assignment,
transfer and conveyance of the GBO Included Business, including, without
limitation, the GBO Subsidiaries Shares (the "Closing"), will take place at the
offices of Rogers & Wells, 200 Park Avenue, New York, New York 10166 at 10:00
A.M., Eastern Time, following the fulfillment or waiver of the conditions
precedent specified in Article XI and XII, on or after January 2, 1997 and on or
before January 31, 1997, unless the parties shall have agreed in writing to such
other date, time and place (the "Closing Date"). The transactions contemplated
by this Agreement shall be effective at 12:01 A.M., Eastern Time, on the Closing
Date, or such other time as the parties shall agree in writing ("Effective
Time").

                  Section 1.5  Closing GAAP Equity Amount.

                  (a) Buyer and Seller agree that the amount of the GBO Included
Assets (including without limitation cash and Investment Assets and including
the GBO Included Assets of the GBO Subsidiaries which are transferred by the
sale of the GBO Subsidiaries Shares) transferred by Seller and accepted by Buyer
pursuant to this Agreement shall be equal to the amount of the GBO Included
Liabilities (and including the GBO Included Liabilities of the GBO Subsidiaries
which are transferred by the sale of the GBO Subsidiaries Shares) assigned by
Seller and assumed by Buyer pursuant to this Agreement, as provided in Section
1.1 hereof and elsewhere herein. Thus, the net equity value of the GBO Included
Business (i.e., the book value of the GBO Included Assets less the book value of
the GBO Included Liabilities as determined pursuant to this Section 1.5) (the
"Closing GAAP Equity Amount") shall be $0. For these purposes, the book value of
the GBO Included Assets and the GBO Included Liabilities shall be determined in
accordance with GAAP applied on a basis consistent with the Agreed GAAP
Principles and Procedures (as defined below) through the preparation and audit
of a balance sheet, which shall represent a consolidated balance sheet of the
GBO Included Business purchased by Buyer at Closing, except that cash and
Investment Assets shall be listed in the amount required to produce a Closing
GAAP Equity Amount of $0 (the "Closing GAAP Balance Sheet"). The Closing GAAP
Balance Sheet and Closing GAAP Equity Amount shall take into account and reflect
the inclusion or exclusion as the case may be of those assets and liabilities
identified in this Agreement. The parties have agreed that the form of Closing
GAAP Balance Sheet attached to this Agreement as Annex K (the "Form of Closing
GAAP Balance Sheet") shall represent the form in which the Closing GAAP Balance
Sheet shall be prepared and that the categories of assets and liabilities set
forth on such balance sheet shall represent the categories of assets and
liabilities to be included on the Closing GAAP Balance Sheet. The net amount of
cash and Investment Assets required to be transferred from Seller to Buyer as
part of the GBO Included Assets, and the timing of such transfers, shall be
determined pursuant to this Section 1.5.

                  (b) Not less than ten (10) Business Days nor more than fifteen
(15) Business Days prior to the Closing, Seller shall make and provide to Buyer
a good faith estimate of the value (the "Estimated Value") of cash and
Investment Assets necessary to result in a Closing GAAP Equity Amount equal to
$0 at the Effective Time. Seller shall at Closing (i) deliver to Buyer cash in
an amount equal to the (i) Estimated Amount minus (ii) an amount, as of such
Business Day, equal to the value of the cash and Investment Assets recorded on
the books of the GBO Subsidiaries (the "Delivery Amount") or (ii) deliver cash
and Investment Assets selected by Buyer in an amount equal to the Delivery
Amount. 


                                       7
<PAGE>   14
Seller has provided Buyer with a list of available Investment Assets of
Seller, which Seller shall revise and update from time to time at the request of
Buyer. Within ten (10) Business Days before Closing, Buyer may notify Seller of
(i) its election to receive a combination of cash and Investment Assets and (ii)
its selection of Investment Assets from the list previously provided by Seller.
For these purposes, Investment Assets that are U.S. Treasury securities or
publicly traded bonds of United States corporations shall be valued at their
published values as of the close of business on the Business Day immediately
prior to the Closing Date as reported in the Wall Street Journal. All Investment
Assets shall be rated in NAIC Categories 1 or 2 at the time of delivery to
Buyer.

                  (c) Promptly following the Closing Date (but not more than one
hundred twenty (120) days thereafter), management of the GBO Included Business
and Buyer shall prepare, in consultation with members of Seller's finance
department senior management, (i) a Closing GAAP Balance Sheet reflecting the
GBO Included Liabilities assigned and assumed on the Closing Date, the GBO
Included Assets other than cash and Investment Assets transferred and accepted
on the Closing Date, and the amount of cash and Investment Assets required to
produce a Closing GAAP Equity Amount of $0, and (ii) a closing statement (the
"Closing Statement") showing either the excess of the amount of cash and
Investment Assets contained in the Closing GAAP Balance Sheet over the Estimated
Amount (the "Deficiency Amount") or the excess of the Estimated Amount over the
amount of cash and Investment Assets contained in the Closing GAAP Balance Sheet
(the "Excess Amount"). A summary of the accounting principles, procedures,
methodologies and assumptions to be employed in the preparation of the Closing
GAAP Balance Sheet is set forth in Annex L hereto (the "Agreed GAAP Principles
and Procedures"). A copy of the Closing GAAP Balance Sheet and the Closing
Statement prepared by the management of the GBO Included Business and Buyer
shall be simultaneously delivered by management of the GBO Included Business to
Buyer, Seller, Coopers & Lybrand and Ernst & Young.

                  (d) Buyer and Seller shall jointly engage Coopers & Lybrand,
under said firm's form of engagement as previously circulated to the parties, to
audit the Closing GAAP Balance Sheet and the Closing Statement following
generally accepted auditing standards and applying the Agreed GAAP Principles
and Procedures. Coopers & Lybrand shall provide a summary of all audit findings
and differences, both favorable and unfavorable, and shall recommend that the
management of the GBO Included Business make such adjustments to the Closing
GAAP Balance Sheet and the Closing Statement prepared by the management of the
GBO Included Business as Coopers & Lybrand shall determine are required for the
Closing GAAP Balance Sheet and the Closing Statement to comply with the
requirements of this Agreement. Coopers & Lybrand shall complete its audit and
issue its report thereon simultaneously to Buyer and Seller within sixty (60)
days after receiving the Closing GAAP Balance Sheet and the Closing Statement
prepared by management of the GBO Included Business. The cost of such engagement
of Coopers & Lybrand shall be borne equally by Seller and Buyer.

                  (e) Seller and Buyer shall be afforded the opportunity to
review the Closing GAAP Balance Sheet and the Closing Statement, as audited by
Coopers & Lybrand, and in that regard shall be afforded full access to the
books, records, and other documents of the GBO Included Business (whether in the
possession of Buyer or Seller) containing information on which the Closing GAAP
Balance Sheet and the Closing Statement are based, as well as the work papers of
Coopers & Lybrand relating to its audit of the Closing GAAP Balance Sheet and
the Closing Statement, for the purpose of conducting a review thereof.
Appropriate confidentiality agreements shall be entered into by the parties in
connection with such review and access. Buyer shall cause the management of the
GBO Included Business to provide reasonable assistance to Seller and its
representatives in connection with such review. To the extent Seller retains
books, records and other documents of the GBO Included Business, including the
work papers of Ernst & Young, Seller shall provide reasonable assistance to
Buyer and its representatives in connection with such review. Seller and Buyer
and their representatives (including, with respect to 


                                       8
<PAGE>   15
Seller, Ernst & Young) shall, to the extent deemed necessary by them, be
permitted to repeat any of the auditing procedures employed by Coopers & Lybrand
in its audit of the Closing GAAP Balance Sheet and the Closing Statement. If
Seller chooses to retain Ernst & Young to perform any procedures with respect to
the Closing GAAP Balance Sheet, Ernst & Young shall complete such procedures
within a period of sixty (60) days after the receipt by Seller of Coopers &
Lybrand's recommended Closing GAAP Balance Sheet and recommended Closing
Statement together with its report thereon. In the absence of manifest error,
the recommended Closing GAAP Balance Sheet and the recommended Closing Statement
shall become final and binding on the parties hereto on the later of (i) the
tenth (10th) or (ii) if Seller chooses to retain Ernst & Young, the seventieth
(70th) Business Day following the day such Closing GAAP Balance Sheet and such
Closing Statement are delivered to Seller and Buyer by Coopers & Lybrand
together with its report thereon, unless either Seller or Buyer shall deliver a
Proposed Adjustment Notice (as defined below) during either period specified
above.

                  (f) If either Seller or Buyer shall object to any
recommendation made, or its failure to make a recommendation, by Coopers &
Lybrand in connection with the Closing GAAP Balance Sheet and the Closing
Statement as not having been made in accordance with the requirements of this
Agreement, then Seller or Buyer, as the case may be, shall deliver to the other
party and Coopers & Lybrand a proposed adjustment notice (the "Proposed
Adjustment Notice"). Seller and Buyer agree that any proposed adjustments shall
be limited to those adjustments required for the Closing GAAP Balance Sheet
and/or Closing Statement to be consistent with the requirements of this
Agreement.

                  (g) If a Proposed Adjustment Notice is delivered within the
period set forth in Section 1.5(e), then Seller and Buyer shall negotiate in
good faith for a ten (10) Business Day period commencing on the date of delivery
of the Proposed Adjustment Notice to resolve such dispute. If Seller and Buyer
cannot resolve such dispute with such ten (10) Business Day period, then Seller
and Buyer shall retain a mutually acceptable firm of independent public
accountants of nationally recognized reputation (other than Coopers & Lybrand,
Ernst & Young or Deloitte & Touche) to act as the arbitrator of such dispute.
Any such arbitration shall be conducted at a location to be determined by the
arbitrator appointed pursuant to the terms hereof. If the parties are not able
to agree to an arbitrator, then the Denver, Colorado office of the American
Arbitration Association shall select a firm of independent public accountants of
nationally recognized reputation (other than Coopers & Lybrand, Ernst & Young or
Deloitte & Touche) to act as arbitrators and the arbitration shall be held in
Denver, Colorado. Seller and Buyer shall cause the arbitrator to act promptly to
resolve any disputed issues in accordance with the terms of this Agreement, and
to issue their written decision within thirty (30) Business Days after the
appointment of the arbitrator, which decision shall be final, binding and
conclusive on both Seller and Buyer.

                  (h) On the day the Closing Statement becomes final and binding
on the parties hereto in accordance with Section 1.5(e) or Section 1.5(g), if
the Closing Statement contains a Deficiency Amount, then Seller promptly shall
pay to Buyer in cash in immediately available funds an amount equal to the
Deficiency Amount plus interest thereon compounded monthly from the Closing Date
to the payment date at the interest rate for 30 day United States Treasury Notes
on the Closing Date as published in the Wall Street Journal. If the Closing
Statement contains an Excess Amount, then Buyer promptly shall pay to Seller in
cash in immediately available funds an amount equal to the Excess Amount plus
interest thereon compounded monthly from the Closing Date to the payment date at
the interest rate for 30-day United States Treasury Notes on the Closing Date as
published in the Wall Street Journal.

                  (i) In an effort to facilitate the audit of the Closing GAAP
Balance Sheet and Closing Statement by Coopers & Lybrand and permit Coopers &
Lybrand to familiarize itself with the books, records and systems of Seller and
with the application of the Agreed GAAP Principles and Procedures, 


                                       9
<PAGE>   16
Seller shall allow Coopers & Lybrand to review the financial books, records and
systems of Seller with respect to the GBO Included Business, to the extent such
review does not unreasonably interfere with the conduct of Seller's business.
Seller shall engage Ernst & Young to assist and cooperate with Coopers & Lybrand
in its review. Such review shall be commenced as soon as practicable following
the execution of this Agreement. Seller shall pay all fees of Ernst & Young and
Buyer shall pay all fees of Coopers & Lybrand for the purpose of such review.

                  Section 1.6 Manner of Payment. Each cash payment required to
be made by any party hereto pursuant to the terms of this Agreement shall be
made by transferring the amount thereof in immediately available United States
Dollars to the account or accounts designated in writing by the party entitled
to such payment.

                  Section 1.7 Fees. Buyer shall pay the filing fee in connection
with any filings made under the Hart-Scott-Rodino Antitrust Improvements Act of
1976, as amended.


                                   ARTICLE II

                    REPRESENTATIONS AND WARRANTIES OF SELLER
              AS TO THE GBO INCLUDED BUSINESS AND GBO SUBSIDIARIES

                  Seller hereby represents and warrants to Buyer as follows:

                  Section 2.1  Organization.

                  (a) Each of the GBO Subsidiaries is a corporation duly
organized, validly existing and in good standing under the laws of its state of
incorporation with the corporate power to own, lease and operate its assets and
carry on the business conducted by it as conducted on the date hereof, and to
carry on that portion of the GBO Included Business conducted by it.

                  (b) Each of the GBO Subsidiaries is duly qualified and is in
good standing as a foreign corporation in each jurisdiction in which such
qualification is required and is necessary to conduct its business except in
such jurisdictions where failure to so qualify could not reasonably be expected
to have a Material Adverse Effect.

                  (c) Neither Seller nor any of the GBO Subsidiaries is required
to be licensed as a third party administrator. Neither TriState nor HASG is
licensed or required to be licensed as a utilization review agent in any
jurisdiction. Seller in the conduct of the GBO Included Business provides
utilization review services only in those jurisdictions listed on Schedule
2.1(c), none of which requires Seller to be licensed, certified, registered or
authorized as a utilization review agent. CCI is duly licensed, certified,
registered or authorized as a utilization review agent in good standing in the
jurisdictions set forth on Schedule 2.1(c), which to the knowledge of Seller are
the only jurisdictions in which such license, certification, registration or
authorization is required.

                  (d) Complete and correct copies of the Certificate of
Incorporation and Bylaws of each of the GBO Subsidiaries, as in effect on the
date hereof, have been delivered to Buyer. Except as set forth on Schedule 2.15,
none of the GBO Subsidiaries has any Subsidiaries nor owns or controls, directly
or indirectly, any shares of capital stock or other interest in any other
corporation, partnership, joint venture or any other enterprise.


                                       10
<PAGE>   17
                  (e) Seller is duly licensed as a life and health insurance
company in good standing in all states of the United States, Guam and Puerto
Rico, and is duly qualified and is in good standing in each jurisdiction in
which such qualification is required and is necessary to conduct the GBO
Included Business.

                  Section 2.2 No Conflict. Except as set forth on Schedule 2.2,
the execution, delivery and performance of this Agreement by Seller (i) do not
and will not conflict with, result in a breach of, or entitle any party (with
due notice or lapse of time or both) to terminate, accelerate or declare a
default with respect to the Certificate of Incorporation or Bylaws of any of the
GBO Subsidiaries, or any GBO Material Contract (with the exception in the case
of GBO Material Contracts of conflicts or breaches arising from violations of
any non-assignment or non-delegation related prohibitions contained in such GBO
Material Contracts) or result in the creation or imposition of any Lien upon the
GBO Subsidiaries Shares or any GBO Included Asset (other than a Permitted Lien
or a Lien removed by Seller or bonded against by Seller to Buyer's satisfaction
at or prior to Closing), and (ii) will not result in any violation of any law,
rule or regulation applicable to Seller or the GBO Included Business, other than
such violations as individually or in the aggregate would not be reasonably
expected to have a Material Adverse Effect.

                  Section 2.3  Financial Statements.

                  (a) Attached hereto as Schedule 2.3(a) are the audited
financial statements containing balance sheets of the GBO Included Business as
of December 31, 1994 and 1995 (collectively, the "Balance Sheets"), and the
related statements of income and cash flows for the fiscal years then ended, in
each case together with the related notes thereto (collectively, "Financial
Statements"). The Balance Sheets (including the related notes thereto) fairly
present the financial condition of the GBO Included Business as of the
respective dates thereof, and the year-end statements included in the Financial
Statements (including the related notes thereto) fairly present the results of
operations of the GBO Included Business for the respective fiscal years then
ended in accordance with GAAP as consistently applied historically by Seller as
set forth in Annex L (except as otherwise set forth therein). The balance sheet
of the GBO Included Business as of December 31, 1995 included in Schedule 2.3(a)
is hereinafter referred to as the "1995 Balance Sheet".

                  (b) Attached hereto as Schedule 2.3(b) are true and complete
copies of the unaudited balance sheet (the "Recent Balance Sheet") of the GBO
Included Business as of June 30, 1996 (the "Recent Balance Sheet Date") and the
related statements of income and cash flows of the GBO Included Business
(collectively, the "Unaudited Financial Statements"). The Recent Balance Sheet
fairly presents the financial condition of the GBO Included Business, as at the
Recent Balance Sheet Date, and the other related unaudited statements included
in the Unaudited Financial Statements fairly present the results of operations
of the GBO Included Business for the period then ended. The Unaudited Financial
Statements have been prepared in accordance with GAAP consistently applied
historically by Seller as set forth in Annex L (except as otherwise set forth
therein), subject to normal and recurring year-end adjustments which were not or
are not expected to be material in amount and are not or may not be necessarily
indicative of results for the full fiscal year, and except that the Unaudited
Financial Statements do not contain full footnote disclosures in accordance with
GAAP.

                  (c) Attached hereto as Schedule 2.3(c) are balance sheets of
the GBO Included Business and the related statements of income of the GBO
Included Business as of and for the fiscal year ending December 31, 1995 and for
the six (6) months ended June 30, 1996, which fairly present the statutory
financial condition and results of operations of the GBO Included Business at
and as of the dates and for the periods indicated therein and have been prepared
in accordance with Statutory Accounting 


                                       11
<PAGE>   18
Principles ("SAP") as consistently applied historically by Seller throughout the
periods indicated, except as expressly set forth therein ("Statutory Financial
Statements"). The Statutory Financial Statements were prepared by Seller and
have not been audited or reviewed by independent accountants.

                  Section 2.4 Undisclosed Liabilities; Absence of Changes.
Except (i) as set forth on Schedule 2.4, (ii) as and to the extent of amounts
specifically reflected or reserved against in the Recent Balance Sheet, and
(iii) Liabilities that have arisen in the ordinary course of business since the
Recent Balance Sheet Date, the GBO Included Business does not have any material
Liabilities of a nature required by GAAP to be reflected in a corporate balance
sheet or disclosed in the notes thereto. Except as disclosed on Schedule 2.4 or
as contemplated by this Agreement, since the Recent Balance Sheet Date, the GBO
Included Business has not suffered any change which would reasonably be
expected, individually or in the aggregate with all such changes, to have a
Material Adverse Effect.

                  Section 2.5 Representations Regarding GBO Included Assets and
Real Property.

                  (a) Except as set forth on Schedule 2.5(a) hereto, Seller has
good and valid title to all the GBO Division Assets wherever situated, subject
to no Liens, other than Permitted Liens and other than Liens removed by Seller
or bonded against by Seller to Buyer's satisfaction at or prior to Closing.
Except as set forth on Schedule 2.5(a) hereto, the GBO Subsidiaries have good
and valid title to all the GBO Included Assets other than the GBO Division
Assets wherever situated, subject to no Liens, other than Permitted Liens and
other than Liens removed by the GBO Subsidiaries or bonded against by the GBO
Subsidiaries to Buyer's satisfaction at or prior to Closing.

                  (b) Schedule 2.5(b) hereto sets forth a complete list of all
real property owned by Seller and all real estate leases entered into by Seller
(as lessee or as lessor, other than leases at the Dearborn facility) and used
principally or exclusively by Seller in the operations of the GBO Included
Business (the "GBO Division Leases") and a complete list of real estate leases
entered into by CCI (the "CCI Leases," and collectively with the GBO Division
Leases referred to herein as the "GBO Leases," and the facilities that are the
subject of the GBO Leases are referred to herein as the "Leased Facilities").
There is no real property owned by CCI. There is no real property owned or real
estate leases entered into by TriState or HASG. The operations of the GBO
Included Business are conducted in the Leased Facilities or in the Dearborn
facility or Seller's headquarters located at John Hancock Place, Boston,
Massachusetts (the Dearborn facility and Seller's headquarters are collectively
defined herein as "Seller's Facilities"). Seller or CCI, as the case may be, has
a valid leasehold interest in all Leased Facilities that are used principally or
exclusively in the GBO Included Business.

                  Section 2.6 Reserves. The aggregate reserves (including any
experience refunds) of the GBO Included Business as recorded in the Recent
Balance Sheet (i) have been determined in accordance with generally accepted
actuarial standards consistently applied (except as set forth therein) and are
fairly stated in accordance with sound actuarial principles; (ii) are consistent
with statutory accounting practices prescribed or permitted by the Insurance
Department of the Commonwealth of Massachusetts (except for adjustments made
thereto reflecting differences between GAAP and SAP); (iii) include adequate
provision for all actuarial reserves and related statement items which ought to
be established under the foregoing standards, principles and practices; and (iv)
are consistent with GAAP and the principles and procedures set forth in Annex L.

                  Section 2.7 Filings and Notices; Approvals and Consents. No
consent, waiver, approval, authorization or order of, or registration,
qualification or filing with, any court or other Governmental Entity is required
for the execution, delivery and performance by Seller of the Transaction
Documents and the consummation by Seller of the transactions contemplated
thereby, other than (i) the filing by 


                                       12

Seller of applications with, and the obtaining of approvals of Buyer's
reinsurance of the Coinsured Policies by, the Department of Insurance of the
Commonwealth of Massachusetts and any other insurance regulatory jurisdictions
listed on Schedule 2.7(i), and the delivery of notices and consents, including
pre- and post-acquisition competition filings, to certain other state insurance
departments, (ii) the delivery of notices of the transfer of ownership of CCI
from Seller to Buyer to, and, to the extent necessary for CCI to conduct
business immediately following the Effective Date, the receipt of consents to
such transfer from and/or the relicensure of CCI to conduct utilization review
by, those regulatory authorities in, those jurisdictions listed on Schedule
2.7(ii), and (iii) compliance with the Hart-Scott-Rodino Antitrust Improvements
Act of 1976, as amended, and expiration of the waiting period thereunder.

                  Section 2.11  Pension Plans.

                  (a) As used herein, "Pension Plan" shall mean any "employee
pension benefit plan" as defined in Section 3(2) of ERISA (other than a
Multiemployer Plan) (A) which (x) is a defined benefit plan which Seller or any
ERISA Affiliate maintained, contributed to or has been required to contribute to
at any time which is no more than six (6) years prior to the Closing Date, or
(y) is a plan intended to be treated as qualified, and which Seller or any ERISA
Affiliate maintained, contributed to or has been required to contribute to at

                  (b) A favorable determination letter has been issued by the

Employees or former GBO Employees of Seller or any of the GBO Subsidiaries with


                                       16
<PAGE>   23
respect to their relationship with Seller or such entities and which has been
treated as qualified under the provision of Code Section 401(a).

                  (c) No Pension Plan will be binding or impose any liability
upon Buyer or the GBO Subsidiaries or any of their respective Subsidiaries after

                  (d) To the knowledge of Seller, no fact or circumstance
exists, including, without limitation, any "reportable event" (within the
meaning of ERISA, but excluding events with respect to which the applicable
notice requirements have been waived), in connection with any Pension Plan which
did or does cover GBO Employees or former GBO Employees of Seller or any of the
GBO Subsidiaries which might constitute grounds for termination of such Pension
Plan by the Pension Benefit Guarantee Corporation (the "PBGC") or of the
appointment by a court of a trustee to administer such Pension Plan.

                  (e) As of January 1, 1996, all of the Pension Plans which did
or does cover GBO Employees or former GBO Employees of Seller or any of the GBO
Subsidiaries were fully funded on an ongoing basis using the actuarial
assumptions used in the most recent actuarial valuations of the Pension Plans.

                  (f) There are no pending or threatened claims (other than
routine claims for benefits) that have been asserted or instituted against any
employee benefit plan, the assets of any employee benefit plan or against the
sponsor, administrator or any fiduciary of any employee benefit plan with
respect to the operation of such employee benefit plan that could subject the
GBO Included Business or any GBO Subsidiary to any liability or expense, nor
does Seller or any GBO Subsidiary have any knowledge of any facts which could
form the basis for any such claim or of any pending investigations by any
governmental agency that could result in any such liability or expense.

and effect would not have a Material Adverse Effect on the GBO Subsidiaries or
the GBO Included Business. To the knowledge of Seller, the consummation of the
transactions contemplated by this 


                                       19

the GBO Subsidiaries has violated or are in violation of any law, rule or

                     REPRESENTATIONS AND WARRANTIES OF BUYER

                  Buyer hereby represents and warrants to Seller that:

organized, validly existing and in good standing under the laws of the State of
California. Unicare is an insurance corporation duly organized, validly existing
and in good standing under the laws of the state of Delaware. Buyer and Unicare
have the corporate power to consummate the transactions contemplated of them,
respectively, by the Transaction Documents, and to carry on the GBO Included
Business following the Closing, to the extent contemplated by the Transaction
Documents.

                  Section 3.2 Authority; No Conflict; Binding Effect. Buyer and
Unicare have the corporate power and authority to execute, deliver and perform
their respective obligations under the Transaction Documents. Such execution,
delivery and performance have been duly authorized by all necessary action on
the part of Buyer and Unicare as the case may be and do not and will not
contravene the organizational documents of Buyer or Unicare or conflict with,
result in a breach of, or entitle any party (with due notice or lapse of time or
both) to terminate, accelerate or cause a default with respect to, any of the
Articles of Incorporation or Bylaws of Buyer or Unicare or any material
agreement or instrument to which Buyer or Unicare is a party or by which Buyer
or Unicare or their respective assets 


                                       21
<PAGE>   28
are bound, except such termination, acceleration or default which individually
or in the aggregate would not have a Material Adverse Effect on either Buyer or
Unicare or the GBO Included Business. The execution, delivery and performance by
Buyer or Unicare, as appropriate, of the Transaction Documents will not result
in any violation by Buyer or Unicare, as appropriate, of any law, rule or
regulation applicable to Buyer or Unicare. Buyer or Unicare is not a party to,
nor subject to or bound by, any judgment, injunction or decree of any court or
other Governmental Entity which may restrict or interfere with the performance
of the Transaction Documents by Buyer or Unicare. This Agreement is (and when
executed and delivered by Buyer or Unicare, as appropriate, each of the
Transaction Documents will be) a valid and binding obligation of Buyer or
Unicare, as appropriate, enforceable against it in accordance with its terms,
except that (i) such enforcement may be subject to bankruptcy, insolvency,
reorganization, moratorium or other similar laws now or hereafter in effect
relating to creditors' rights generally and (ii) the remedy of specific
performance and injunctive relief may be subject to equitable defenses and to
the discretion of the court before which any proceeding therefor may be brought.

                  Section 3.3 Filings and Notices; Approvals and Consents. No
consent, waiver, approval, authorization or order of, or registration,
qualification or filing with, any court or other Governmental Entity is required
for the execution, delivery and performance by Buyer or Unicare of the
Transaction Documents and the consummation by Buyer of the transactions
contemplated thereby, other than (i) the filing by Unicare of applications with,
and the obtaining of approvals of Buyer's reinsurance of the Coinsured Policies
by, the Department of Insurance of the State of Delaware, the Department of
Insurance of the State of California and the other insurance regulators listed
on Schedule 2.7, and the delivery of notices and consents, including pre-and
post-acquisition competition filings, to certain other state insurance
departments, and (ii) compliance with the Hart-Scott-Rodino Antitrust
Improvement Act of 1976, as amended, and expiration of the waiting period
thereunder. No consent or waiver of any party to any material contract to which
Buyer or Unicare is a party is required for the execution, delivery and
performance by Buyer or Unicare of the Transaction Documents or the conduct of
the GBO Included Business following the Closing.

                  Section 3.4 Brokers or Finders. Except for Lazard Freres & Co.
LLC, the fees of which shall be paid by Buyer, neither Buyer nor its Affiliates
has retained any agent, broker, investment banker, financial advisor or other
firm or person that is or will be entitled to any broker's or finder's fee or
any other commission or similar fee in connection with any of the transactions
contemplated by the Transaction Documents. Buyer agrees to indemnify and hold
Seller harmless from and against any and all loss, claims, damage, cost, or
expense arising out of or in connection with any claim against Seller or its
Affiliates for any such broker's or finder's fee, other commission or similar
fee resulting from actions taken by Buyer. Buyer's obligations under this
Section 3.4 shall be from the first dollar and shall not be subject to any
threshold amount or limitation.

                  Section 3.5 Investment Intent. Buyer is acquiring the GBO
Subsidiaries Shares for its own account for investment and not with a view to
the distribution thereof, and Buyer shall not offer to sell or otherwise dispose
of any of the GBO Subsidiaries Shares so acquired by it in violation of the
registration requirements of the Securities Act or applicable state securities
laws.

                  Section 3.6 Actions Pending. There is no action, suit,
investigation or proceeding pending or, to the knowledge of Buyer, threatened
against Buyer or Unicare or any of its properties or rights by or before any
court, arbitrator or administrative body or Governmental Entity which questions
the validity of the Transaction Documents or any action taken or to be taken
pursuant thereto which could reasonably be expected to impair or restrict
Buyer's or Unicare's ability to perform its obligations thereunder or to
consummate the transactions contemplated by the Transaction Documents.

Agreement and prior to the Closing, (i) were or will be prepared in all material

                         REPRESENTATIONS AND WARRANTIES
                             OF SELLER AS TO ITSELF

                  Seller hereby represents and warrants to Buyer that:

                  Section 4.1 Organization. Seller is a mutual life insurance
corporation duly organized, validly existing and in good standing under the laws
of the Commonwealth of Massachusetts and has all requisite power and authority
to own (directly, or indirectly through JHSI) the GBO Subsidiaries Shares and to
carry on, directly or indirectly, the GBO Included Business.

                  Section 4.2 Authority; No Conflict; Binding Effect. Seller has
the corporate power and authority to execute, deliver and perform its
obligations under the Transaction Documents. Such execution, delivery and
performance have been duly authorized by all necessary action on the part of
Seller and do not and will not contravene the organizational documents of Seller
or conflict with, result in a breach of, or entitle any party (with due notice
or lapse of time or both) to terminate, accelerate or call a default with
respect to, any agreement or instrument to which Seller is a party or by which
Seller or the GBO Included Assets are bound, except such termination,
acceleration or default which individually or in the aggregate would not have a
Material Adverse Effect on the GBO Included Business. The approval of the
policyholders of Seller is not required in connection with the execution,
delivery and performance by Seller of the Transaction Documents (other than the
approval of policyholders of Coinsured Policies under the Assumption Reinsurance
Agreement) or the consummation by Seller of the transactions contemplated
thereby. The execution, delivery and performance by Seller of the Transaction
Documents will not result in any violation by Seller of any law, rule or
regulation applicable to Seller. Seller is not a party to, nor subject to or
bound by, any judgment, injunction or decree of any court or other Governmental
Entity which may restrict or interfere with the performance of the Transaction
Documents by Seller. This Agreement is (and when executed and delivered by
Seller each of the Transaction Documents will be) a valid and binding obligation
of Seller enforceable against Seller in accordance with its terms, except that
(i) such enforcement may be subject to bankruptcy, insolvency, reorganization,
moratorium or other similar laws now or hereafter in effect relating to
creditors' rights generally or the rights of creditors of insurance companies
generally and (ii) the remedy of specific performance and injunctive relief may
be subject to equitable defenses and to the discretion of the court before which
any proceeding therefor may be brought.

                  Section 4.3 Filings and Notices; Approvals and Consents.
Except as set forth on Schedule 2.7, no consent, waiver, approval, authorization
or order of, or registration, qualification or filing with, any court or other
Governmental Entity is required for the execution, delivery and performance by
Seller of this Agreement and the consummation by Seller of the transactions
contemplated hereby. Except as otherwise disclosed or expressly provided for in
this Agreement, no consent or waiver of any party to any Contract to which
Seller is a party or by which it is bound is required for the execution,
delivery and performance by Seller of the Transaction Documents.

                  Section 4.4 Title to GBO Subsidiaries Shares. JHSI is the
record and beneficial owner of, and has good and valid title to, the GBO
Subsidiaries Shares free and clear of all Liens. Other than 


                                       25
<PAGE>   32
as contemplated by this Agreement, Seller is not a party to, or bound by, any
agreement, instrument, proxy, understanding or commitment restricting the
transfer of the GBO Subsidiaries Shares. No Person other than JHSI is the record
or beneficial owner of any of the GBO Subsidiaries Shares. Assuming Buyer has
the requisite power and authority to be the lawful owner of the GBO Subsidiaries
Shares and is a "bona fide purchaser" (as defined under applicable law), upon
delivery to Buyer at the Closing of certificates representing the GBO
Subsidiaries Shares, duly endorsed by JHSI for transfer to Buyer or with stock
powers attached, and upon Seller's receipt of the Purchase Price therefor, good
and valid title will pass to Buyer, free and clear of all Liens other than those
arising from acts of Buyer or its Affiliates.

                  Section 4.5 Actions Pending. There is no action, suit,
investigation or proceeding pending or, to the knowledge of Seller, threatened
in writing against Seller or any of its properties or rights by or before any
court, arbitrator or administrative body or Governmental Entity which questions
the validity of the Transaction Documents or any action taken or to be taken
pursuant hereto which could reasonably be expected to impair or restrict
Seller's ability to perform its obligations hereunder.


                                    ARTICLE V

                               COVENANTS OF SELLER

                  Section 5.1 Operation of the Business. Except as specifically
provided in this Agreement, prior to Closing Seller will conduct the GBO
Included Business in the ordinary course and substantially in the same manner as
heretofore conducted and in accordance with applicable law and will use
reasonable efforts to cause the GBO Included Business to be diligently carried
on, in the ordinary course consistent with past practice. In furtherance
thereof, Seller shall use reasonable efforts to (i) preserve the GBO Included
Assets, including, without limitation, the ASO Contracts and the Existing GBO
Policies and the material permits and licenses necessary to conduct the GBO
Included Business in full force and effect, (ii) keep available the services of
the senior staff of the GBO Included Business, (iii) keep intact the workforce,
taken as a whole, of the GBO Included Business so that the conduct of the GBO
Included Business as presently conducted is not impeded, (iv) maintain present
suppliers and customers of the GBO Included Business, and (v) preserve the
goodwill of the GBO Included Business. Without limiting the foregoing, prior to
the Closing, Seller (unless otherwise consented to in writing by Buyer):

                  (a) will give prompt notice to Buyer of (i) any breach or
default (or notice thereof) of any of the GBO Material Contracts or (ii) any
other event that could reasonably be expected to have a Material Adverse Effect
on the GBO Included Business;

                  (b) will not amend, alter or modify any material provision of
any GBO Material Contract except as may be deemed necessary to maintain
compliance with applicable laws, rules or regulations;

                  (c) will not increase in any manner the rate of compensation
or bonus of any of the GBO Employees, other than (i) increases in the ordinary
course of business consistent with past practice and other increases in
compensation customary on a periodic basis or required by agreement or
understanding and (ii) bonus and incentive arrangements entered into by Seller
in contemplation of the sale of the GBO Included Business, except as provided in
Article X hereof, and for which Seller assumes sole responsibility and
Liability;


                                       26
<PAGE>   33
                  (d) will not increase in any substantial amount the number of
GBO Employees, or, increase the terms of any insurance, pension or other
employee benefit plan, payment or arrangement made to, for or with any such GBO
Employees, except as provided in Article X hereof;

                  (e) will not make any material change in accounting methods or
practices or in actuarial reserving practices with respect to the GBO Included
Business, including, without limitation, any change with respect to
establishment of reserves for unearned premiums, losses (including without
limitation the current practice of calculating the reserve for incurred but not
reported losses) and loss adjustment expenses, or any change in depreciation or
amortization policies or rates adopted by it, except as required by law or GAAP
(and Seller shall advise Buyer of any change so required);

                  (f) without prior consultation with Buyer, will not, and will
not permit any of the GBO Subsidiaries to, make or propose to make any material
change from the past underwriting, investment and other insurance practices of
the GBO Included Business (including practices for the processing of claims and
the issuance of explanations of benefits or non-benefits), or permit any of the
GBO Subsidiaries to buy any investment asset rated Below Investment Grade;

                  (g) will not permit any of the GBO Subsidiaries to pay any
dividend or make any distribution of cash or assets to Seller or any Affiliate
of Seller; provided, however, that Seller may cause each GBO Subsidiary to make
payments from time to time to Seller and Affiliates of Seller on account of
service fees, expense charges, insurance fees, overhead charges, taxes and other
fees and charges consistent with past practices; and

                  (h) will not enter into any Contract to do any of the
foregoing in clauses (b) through (g) inclusive.

                  Section 5.2 Access. Seller will permit Buyer and its
authorized representatives at all reasonable times, without unreasonable
disruption of the normal operations of the GBO Included Business, to have access
to and to examine all premises, properties, files, books, documents, records,
financial information (including working papers and data in the possession of
Seller's independent public accountants, internal audit reports, and "management
letters" from such accountants with respect to the systems of internal control
of the GBO Included Business) and other information relating to the GBO Included
Business (including the right to make extracts therefrom or copies thereof), and
will cooperate with Buyer in its investigation of the GBO Included Business.
Seller will permit representatives of Buyer, to the extent reasonably necessary
or desirable, to consult with GBO Employees concerning all financial and
operational matters relating to the GBO Included Business. Seller may take such
steps as are reasonably appropriate in the circumstances to protect the
confidentiality of information that does not relate to the GBO Included Business
that is contained in books and records that include information relating to the
GBO Included Business. To the extent permitted by law, Seller will transfer to
Buyer at or immediately following the Closing physical possession of all
original files, books, documents, records and financial and other information
related to the GBO Included Business. To the extent Seller is prohibited by law
from transferring any of such original files or other information, Seller shall
provide true and correct copies of such files and information to Buyer.

                  Section 5.3 Additional Financial Statements. As soon as
reasonably practicable after they become available, Seller shall furnish to
Buyer the unaudited GAAP financial statements of the GBO Included Business for
all interim quarterly and annual periods subsequent to the Recent Balance Sheet
Date but prior to the Closing Date, which shall be prepared in accordance with
GAAP consistently applied with the 1995 Financial Statements.

<PAGE>   34
                  Section 5.4 Third-Party Reinsurance Agreements. Except
pursuant to the Underwriting Manager Agreement between Seller and James E.
Hackett Reinsurance Corporation, effective April 1, 1991, Seller shall not,
without the prior written approval of Buyer, which approval will not be
unreasonably withheld, (i) enter into or commit to enter into any commutation,
loss portfolio transfer or other similar transaction, agreement or arrangement
or series of related transactions, agreements or arrangements involving any
assumed or ceded reinsurance included in the GBO Included Business or (ii) enter
into or commit to enter into any new reinsurance Contract, treaty or other
arrangement or series of such Contracts, treaties or other arrangements that
create any GBO Included Liability.

                  Section 5.5 Updating of Information. From the date hereof
until the Closing Date, Seller will promptly inform Buyer in writing of Seller's
knowledge of the occurrence or failure to occur of any action or event which
would violate its representations and warranties hereunder or render them
inaccurate as of the date hereof, or that would constitute a breach of any
covenant of Seller hereunder or a failure of any condition to the obligations of
Seller hereunder. Through the Closing date, Seller may supplement any Schedule
or Annex hereto; provided, however, that the delivery of any such supplement
shall not cure any breach of representation or warranty requiring disclosure of
such matter at the date hereof.

                  Section 5.6 Employment Loss. Without regard to the actions
contemplated by Section 10.1, Seller will not take any action in respect of the
GBO Employees within the 90-day period prior to the Closing Date which would
result in an "employment loss" (as defined in the WARN Act).

                  Section 5.7 GBO Employees. Prior to the second anniversary of
the Closing Date, without the consent of Buyer, Seller shall not knowingly
re-employ or attempt to re-employ any former GBO Employee who has been employed
by Buyer pursuant to Section 10.1; provided, however, that this Section 5.7
shall not prohibit Seller from employing any such individual whose employment
with Buyer or its Affiliates has been involuntarily terminated. Notwithstanding
any other provision of this Agreement to the contrary, the covenant set forth in
this Section 5.7 will survive the Closing for a period of two (2) years.

                  Section 5.8  Regulatory Filings, etc.

                  (a) Seller shall use all reasonable efforts to prepare and
file with the Department of Insurance of the Commonwealth of Massachusetts (the
"Massachusetts Department"), and the Departments of Insurance in New York,
Wisconsin, Connecticut and Colorado as promptly as practicable, such
documentation which Buyer, acting in good faith, believes is reasonably
necessary to obtain such Departments' review of Buyer's application to reinsure
the Coinsured Policies.

                  (b) Seller shall use all reasonable efforts to prepare and
file, as promptly as practicable, all applications, forms and other
documentation related to the approvals and consents contemplated by Section 2.7
which Buyer, acting in good faith, believes to be reasonably necessary in order
(i) to notify the applicable Governmental Entity, and (ii) if applicable, to
obtain a review by and a decision from the applicable Governmental Entity in
connection with the consummation of the transactions contemplated hereby.

                  Section 5.9  Covenant Not to Compete.

                  (a) So long as Buyer or its Affiliates is in the same line of
business in the United States, for a period of five (5) years from the date of
this Agreement, neither Seller nor any Affiliate of Seller shall, directly or
indirectly, offer in the United States such managed care or group or individual


                                       28
<PAGE>   35
health (including, without limitation, group or individual pharmacy, dental or
vision products, or accident and sickness), long-term disability or short-term
disability insurance products, administrative services relating to managed care
or health or long-term disability or short-term disability benefits
(collectively, the "Subject Business").

                  (b) Subject to the provisions of Section 5.9(c) below, the
covenant not to compete contained in this Section 5.9 shall not apply to any
acquisition after the Closing Date by Seller or any Affiliate of Seller of (i) a
Person that is engaged in a business that is substantially similar to the
Subject Business, if such business is incidental to a substantially larger
business conducted by the Person which is not substantially similar to the
Subject Business, or (ii) a Person that is engaged in a business that is
substantially similar to the Subject Business, if such Person is acquired as
part of a substantially larger transaction where such Person is not the
principal Person acquired in such larger transaction. Seller agrees to negotiate
in good faith with Buyer on an exclusive basis for a period of ninety (90) days
following any acquisition described in the immediately preceding sentence to
determine whether Seller and Buyer can agree upon the sale to Buyer of the
business that is substantially similar to the Subject Business; provided,
however, that Seller shall not be obligated to sell such business to Buyer, and
Buyer shall not be obligated to purchase such business from Seller, unless
Seller and Buyer execute a definitive agreement relating thereto on terms and
conditions acceptable to each party in its sole discretion; and, provided,
further, that Seller and its Affiliates shall have no obligations with respect
to such business under this Section 5.9 if Seller and Buyer after such good
faith negotiations do not execute such a definitive agreement for the sale of
such business during such ninety (90) day period. In addition, the covenant not
to compete contained in this Section 5.9 shall not apply to any Person if such
Person becomes an Affiliate of the Seller by virtue of such Person or an
Affiliate of such Person having acquired all or part of the Seller and such
Person conducted a business that is substantially similar to the Subject
Business for at least twelve (12) months prior to such acquisition.

                  (c) Notwithstanding anything contained in Section 5.9(b) to
the contrary, in the event Seller or any Affiliate of Seller is relieved of its
obligation under Section 5.9(a) as described under Section 5.9(b), Seller shall
not utilize the "John Hancock" name or any derivative thereof in brochures,
advertisement or other materials used in marketing business that is the same or
substantially similar to the Subject Business during the period that the
covenant not to compete contained in Section 5.9(a) would otherwise apply.

                  Section 5.10 Amounts Due to or Due From Affiliates. Except
with respect to amounts due under the following Contracts, which Contracts will
remain in effect following the Closing, (i) the service agreement between Seller
and CCI, effective July 1, 1990, as described in item (vii)(a)(3) of Schedule
2.8(b), for CCI to provide utilization review services to Seller; (ii) the
Contracts described in item (vii)(b) of Schedule 2.8(b), (iii) the Maritime Life
Insurance Company 100% Quota Share Reinsurance Agreement described on Exhibit C

administrative services described in Section 8.10, and (v) the Transaction
Documents, all other amounts due to or due from Affiliates of the GBO
Subsidiaries or the GBO Included Business shall be settled at face value at or
prior to Closing.

                  Section 5.11 Termination or Modification of Existing GBO
Policies. After the Closing, Seller shall, as requested by Buyer, terminate,
amend or otherwise modify any Existing GBO Policy, to the extent permitted by
the terms of such Existing GBO Policy, the Coinsurance Agreement and the
Administration Agreement and by applicable law, or otherwise modify the terms or
pricing, subject to the terms and conditions of the Administration Agreement,
upon renewals effective at or prior to the time such Existing GBO Policy is
transferred onto Unicare forms.

                  Section 5.12  Healthcare Providers and Networks.

                  (a) As promptly as practical after execution of this
Agreement, Seller will provide to Buyer a computer generated schedule showing on
a state by state basis, the name (listed alphabetically), address, zip code, tax
identity number, specialty and applicable payment code for each health care
provider participating in a network established, managed or utilized by Seller
or an Affiliate in the conduct of the GBO Included Business, and access to
Seller's files and records with respect to each such provider.

                  (b) Buyer (or Unicare) and Seller shall, if requested by Buyer
(or Unicare, as the case may be), immediately upon execution of this Agreement
jointly engage one or more vendors who are not Affiliates of Buyer or Seller to
review all of Seller's (and/or its Affiliates') existing agreements with health
care providers participating in networks established or managed by Seller in
providing services to subscribers of the GBO Included Business, whether or not
listed in Seller's provider directories (the "GBO Providers") and where
necessary use reasonable commercial efforts to obtain valid and binding
amendments to such existing agreements or new agreements so that Unicare will be
assured that (i) a valid and binding agreement exists with each GBO Provider and
(ii) the subscribers of the GBO Included Business, Unicare and Seller are
entitled to the negotiated discounted fee structure. In the case of provider
networks not established or managed by Seller, the outside vendor shall also
review Seller's agreements with such provider networks and shall engage in
appropriate discussions with such provider networks to facilitate assignment of
the agreements to Unicare and appropriate amendments thereto to assure that
Unicare has the benefit of those agreements. The period of engagement for each
such vendor shall not exceed one year from the date of this Agreement. Buyer (or
Unicare) and Seller shall each pay one-half of the costs and expenses of each
such vendor. The obtaining of such valid and binding amendments and agreements
shall not be a condition to Closing under this Agreement.

                  (c) With respect to claims incurred by subscribers of the GBO
Included Business prior to the Effective Time and during the 90-day period
immediately following the Closing Date, if the GBO Provider with respect to such
claims alleges that such GBO Provider does not have at the time a valid and
binding agreement with Seller or Unicare, as the case may be, and as a result
such GBO Provider will not provide a discount (after Unicare makes commercially
reasonable efforts to obtain such a discount) in an amount equal to the discount
expected to be available to Seller at the Effective Time under contracts or
arrangements with such GBO Provider, then Seller shall promptly pay to Unicare
the amount by which the discount available to Seller exceeds the discount, if
any, available to such subscriber.

                  (d) Seller shall on demand indemnify, defend and hold harmless
Buyer and its Affiliates, and their respective directors, officers and employees
from and against any and all demands, actions, proceedings, costs and
Liabilities (including, without limitation, the costs and expenses of defending
any and all actions, suits, proceedings, demands, assessments, judgments,
settlements and compromises and attorneys' fees in connection therewith), paid
or incurred, resulting from, arising out of or relating to Seller's failure to
have appropriately credentialed the GBO Providers; provided, however, that
Seller's obligation to indemnify Buyer shall be limited to claims arising prior
to Closing and the one hundred eighty (180) day period following Closing. The
Liability of Seller pursuant to this Section 5.12(d) shall not be subject to the
threshold articulated in Article XIV, but shall be measured from the first
dollar.

until the Closing Date, Buyer will (i) keep Seller informed of the progress of
all regulatory and other filings required to be made by Buyer pursuant to
Section 6.4 and 7.3 and (ii) promptly inform Seller in writing of Buyer's
knowledge of the occurrence or failure to occur of any action or event that
would violate its representations or warranties hereunder or render them
inaccurate as of the date hereof, or would constitute a breach of any covenant
of Buyer hereunder or a failure of any condition to the obligations of Buyer
hereunder.

                  Section 6.2 Post-Closing Access by Seller. Buyer shall, and
shall cause its Affiliates to, permit Seller and its authorized representatives
at all reasonable times, without unreasonable disruption of the normal
operations of the GBO Included Business, to have access to and to examine all
premises, properties, files, books, documents, records, financial and tax
information (including working papers and data in the possession of Buyer's
independent financial accountants, internal audit reports and "management
letters" from such accountants with respect to the systems of internal control
of the GBO Included Business), computerized information and other information
(including the right to make extracts therefrom or copies thereof at Seller's
sole cost and expense) in connection with (i) any audit or other investigation
by any Taxing Authority or any required reports or submissions to any
Governmental Entity with respect to the GBO Included Business, (ii) Third Party
Claims (as defined in Section 14.2) and investigations and insurance relating
thereto and (iii) litigation relating to the GBO Included Business and involving
the Seller and (iv) transitional matters and activities of any of the GBO
Subsidiaries pursuant to Article VIII; provided, however, compliance by Buyer
with provisions of this Section 6.2 shall not constitute a waiver of Buyer's
attorney-client privilege. Buyer shall, and shall cause its Affiliates to,
preserve and maintain such files, books, documents, records, financial and tax
information, computerized information and other information for the greater of
(A) the period during which Buyer may make a claim against Seller for
Indemnifiable Losses (as defined in Section 14.1) hereunder or (B) five (5)
years and, thereafter, shall dispose of the same only after it shall have given
Seller prior notice of such disposition and the opportunity to remove and retain
such files, books, documents, records, financial and tax information,
computerized information and other information. Buyer shall, and shall cause its
Affiliates to, permit Seller or its representatives, to the extent reasonably
necessary or desirable, to consult with GBO Employees concerning all financial
and operational matters in connection with proceedings, claims and requirements
described in clauses (i), (ii), (iii) and (iv) above.

Buyer, acting in good faith, believes is reasonably necessary to obtain Delaware
Department's review of Unicare's application to reinsure the Coinsured Policies.

                  (b) Buyer shall use all reasonable efforts to prepare and file
such documentation which Buyer, acting in good faith, believes is reasonably
necessary to obtain approval of the acquisition of CCI under statutes providing
for regulation of utilization review agents.

file, or to cause its Affiliates to prepare and file, as appropriate, as

                  Section 7.1  Filings and Notices; Approvals and Consents.

                  (a) Seller and Buyer will, as promptly as practicable after
the execution and delivery of this Agreement (or at or prior to the date
otherwise agreed herein), cooperate to make and give all governmental filings
and governmental and third party notices (and to provide requested information
supplemental thereto) required to be made or given by Seller or Buyer, including
those described in Sections 2.7 and 3.3 and on Schedule 11.5 in order to
consummate the transactions contemplated by this Agreement. Any such filing, and
any supplemental information requested by the relevant Governmental Entity in
connection therewith, shall be in substantial compliance with the requirements
of such Governmental Entity. Seller and Buyer will keep each other apprised of
the status of the governmental approval process and of any communications with,
and any inquiries or requests for additional information from, the relevant
Governmental Entity, and will comply promptly with any such inquiry or request.
Seller and Buyer will use their respective reasonable best efforts to promptly

                  (b) Seller and Buyer will furnish to each other such necessary

applications shall include, but are not limited to, making form and rate filings
in all jurisdictions where such filings are required for the conduct of the GBO
Included Business. Buyer, with Seller's cooperation, will use reasonable efforts
to obtain approval of such forms and rates as promptly as possible. For purposes
of this Section 7.3, "reasonable efforts" shall include, but not be limited to,
the use of reference filings, where appropriate, with respect to policy forms
and rates.

                  Section 8.3  Reinsurance.

                  (a) At the Effective Time, Unicare shall reinsure Existing GBO

Transition GBO Policies as requested by Unicare, which shall automatically and
immediately be 100% coinsured by Unicare pursuant to the terms and conditions,
and subject to the limitations, set forth in the Coinsurance Agreement.

                  (c) From and after the Effective Time, Unicare shall provide

notices to policyholders and obtaining any required policyholder consents, for
the assumption reinsurance of Coinsured Policies on the terms and conditions,
and subject to the limitations, set forth in the Assumption Reinsurance
Agreement which Seller and Unicare will enter into at the Closing. Any such
assumption reinsurance will be effected in a manner creating a novation and
complete release of liability (subject to the terms of the Assumption
Reinsurance Agreement) of Seller under the Coinsured Policies being assumption
reinsured, with Unicare being substituted as the insurer thereunder.

                  Section 8.4 Transitional Marketing Arrangements. In order to
assist in effectively implementing the reinsurance arrangements described in
Section 8.3(b), Seller will permit Unicare and its Affiliates to market the

Administration Agreement to be entered into by Seller and Unicare at the
Closing.

                  Section 8.5 Use of Name Post-Closing. The rights of Unicare
and its Affiliates to use the Names following the Closing Date will be governed
by the terms of the License Agreement.

                  Section 8.6 Change of HASG Name. The name of HASG shall be
changed to remove any reference to "Hancock" before the Closing.

                  Section 8.7  Lease of Furniture, Fixtures and Equipment.

                  (a) Subject to the provisions of this Section 8.7, Seller
hereby grants to Buyer or its assignee (and by its acceptance of any such
assignment, such assignee shall be deemed to have agreed to the terms and
conditions of this Section 8.7), a license to use all furniture, fixtures and
equipment (the "Leased Equipment") held under the Leases (as hereinafter
defined) for use by the GBO Employees in operating the GBO Included Business and
identified pursuant to the Inventory to be conducted by Buyer pursuant to
subsection (d) below for the period commencing on the Closing Date and ending
eight (8) years thereafter (the "Use Period"). Such license shall be (i)
revocable to the extent, and only to the extent, set forth in this Section 8.7,
and (ii) without additional cost to Buyer or its assignee. All costs 


                                       33
<PAGE>   40
and expenses of Seller under the Leases shall be borne solely by Seller and none
of such costs and expenses shall be borne by Buyer or its assignee.

                  (b) For purposes of this Section 8.7, (i) the term "Lease"
means the 1987 Lease or the 1988 Lease, as the case may be; (ii) the term
"Leases" means the 1987 Lease and the 1988 Lease; (iii) the term "1987 Lease"
means that certain Lease Agreement dated as of December 23, 1987 between JHM
Funding, Inc. as lessor (the "Lessor") and Seller as lessee, as amended by
Amendment No. 1 dated as of November 17, 1988 and Amendment No. 2 dated as of
November 30, 1994, and as further amended, supplemented or modified from time to
time; and (iv) the term "1988 Lease" means that certain Lease Agreement dated as
of November 17, 1988 between the Lessor as lessor and Seller as lessee, as
amended by Amendment No. 1 dated as of November 30, 1994, and as further
amended, supplemented or modified from time to time. Buyer acknowledges that it
has been provided with a copy of the Leases as in effect on the date hereof,
that it has reviewed same and is familiar with the terms thereof, and that some
of the Leased Equipment is leased to Seller under the 1987 Lease and some of the
Leased Equipment is leased to Seller under the 1988 Lease. Subject to the terms
of subsection (f) below, Seller agrees to deliver to Buyer a copy of any
amendment, supplement or modification of each Lease reasonably promptly after
the same shall have become effective.

                  (c) Buyer agrees that, without Seller's prior written consent,
which shall not be unreasonably withheld or delayed (it being agreed that the
refusal of the Lessor to grant any consent required under the Leases shall
constitute a reasonable basis to withhold consent), it shall (i) not have any
right to assign, sublease or relinquish possession of the Leased Equipment to
any party (other than to Unicare); (ii) not change the location of the Leased
Equipment; and (iii) not do, or omit to do, any act or omission which would
constitute an Event of Default under either or both of the Leases.

                  (d) As soon as reasonably practical after the Closing, Buyer
shall cause a physical inventory (the "Inventory") to be taken of the Leased
Equipment solely for the purpose of locating and identifying the Leased
Equipment and for no other purpose, and upon completion thereof shall promptly
provide a certified copy of the Inventory to Seller. Such Inventory shall be
completed at the expense of Buyer. Seller shall cooperate in all reasonable
respects with Buyer in connection with the taking of the Inventory.

                  (e) On the last day of the Use Period or such earlier date as
may be specified by Buyer from time to time as to all or any portion of the
Leased Equipment, Buyer or its assignee shall make available to Seller the
Leased Equipment or portion of the Leased Equipment, as the case may be, at the
same location as the Leased Equipment, or particular piece of Leased Equipment,
shall have been delivered to Buyer on the Closing Date or such other location
where such Leased Equipment shall be located at such time (after having received
consent to the move of the Leased Equipment in accordance with subsection (c)
above) in the same condition as received, reasonable wear and tear excepted.
Upon termination of use by Buyer or its assignee, Buyer or its assignee shall
give at least 30 days' advance notice to Seller of such termination, and it
shall be Seller's responsibility to remove or recover the Leased Equipment and
bear all costs associated with its return to the Lessor.

                  (f) Buyer hereby acknowledges and agrees that its rights under
this Section 8.7 to use the Leased Equipment are expressly subject and
subordinate to the provisions of the Leases and are subject to termination upon
termination of either or both of the Leases for any reason permitted thereunder,
and neither the provisions of this Section 8.7 nor the use of the Leased
Equipment by Buyer hereunder shall in any way be construed as a modification or
limitation of any right or power the Lessor may have under the Leases.
Notwithstanding the foregoing, however, (i) Buyer shall have a right of quiet
enjoyment with respect to the Leased Equipment during the Use Period on the
terms and conditions 


                                       34
<PAGE>   41
provided in the Leases without any interference from Seller or the Lessor or
anyone claiming through or under Seller or the Lessor, (ii) Seller shall not
propose or consent to any amendment, modification or termination of any term of
the Leases during the Use Period that would materially adversely impact the
right of Buyer or its assignees to use the Leased Equipment during the Use
Period, and (iii) Seller shall comply in all material respects with its
obligations under the Leases.

                  (g) All Leased Equipment shall be delivered in "as-is"
condition, and is located in the premises covered by the Lease Agreements and
the Lease Assignments, without material diminution from the date hereof.

                  (h) The provisions of this Section 8.7 shall survive the
Closing indefinitely.

                  Section 8.8 Transfer of MIS Software. Seller shall transfer to
Unicare all computer hardware used exclusively in the GBO Included Business, and
all the software applications, programs and licenses used exclusively in the GBO
Included Business (including without limitation those listed in Attachment 1 to
Appendix C to the Service Agreement), which hardware and software are owned by
Seller, as a part of the GBO Division Assets. Seller shall provide under the
Service Agreement on the terms set forth therein such computer hardware as is
used by Seller in both its GBO Included Business and its other businesses and
software applications, programs and licenses included in the Shared Contracts.
Seller shall also transfer, license or otherwise provide to Buyer all other
software applications, programs and licenses from third parties and used by
Seller in the conduct of the GBO Business, (including without limitation those
listed in Attachment 1 to Appendix C to the Service Agreement) (together with
the owned software described in the first sentence of this Section 8.8, the "MIS
Software"), as shall be reasonably necessary, together with the transferred
owned hardware and software (but excluding Shared Contracts and Seller's
mainframe computer), for Buyer to operate the management information, accounting
and billing systems currently operated by the GBO Included Business at a level
of functionality comparable to that enjoyed by the GBO Included Business at the
time of Closing, but not an increased level of functionality associated with an
increased number of employees or volume of the GBO Included Business and not at
locations not occupied by the GBO Included Business at the time of Closing. In
making and arranging for such transfer, Seller agrees that it will be
responsible for (i) any one-time charge imposed on Buyer or Seller by the vendor
of any such Shared Contracts or MIS Software in connection with the transfer to
Buyer thereof or the provision of services by Seller under the Service Agreement
and (ii) any increase in the periodic payments of license costs and other
charges associated with any such Shared Contracts or MIS Software imposed on
Buyer by the vendor thereof during the two-year period following the Closing (or
following the transfer in the case of MIS Software transferred to Buyer) above
the license cost and other charges imposed by such vendor on Seller prior to the
Closing, in each case, arising solely as a result of the consummation of the
transactions contemplated by this Agreement and not attributable to an increase
in the number of employees of the GBO Included Business or a change in the
volume of business or a second or subsequent change in the location of the GBO
Business after the relocation from the Berkeley Headquarters Building.

                  Section 8.9 Commissions and Expenses Due. All commissions and
expenses due with respect to third party reinsurers which are included in the
Closing GAAP Balance Sheet and are not collected within three hundred sixty-five
(365) days of the day on which such commissions and expenses shall have become
due under their original terms shall be transferred back to Seller, and Seller
concurrently with such transfer shall pay Buyer therefor the amount at which
such items shall have been included in the Closing GAAP Balance Sheet. Buyer
shall attempt in good faith, using commercially reasonable efforts, (i) during
the three hundred sixty-five (365) day period following the Closing to collect
or settle such commissions and expenses due, and (ii) during the period
following such three hundred sixty-five (365) days to collect or settle from the
applicable third party reinsurer any amounts represented by amounts transferred
to Seller pursuant to the preceding sentence. Any amounts collected or settled
by Buyer under clause (ii) above shall be remitted promptly to Seller.

                  Section 8.10 Seller Life and Health Account. In order to
ensure life and health coverage for Seller's employees for the next calendar
year, both Seller and Buyer agree that for a period beginning as of the Closing
and ending on the first anniversary of the Effective Time, Seller shall contract
with Buyer or an Affiliate of Buyer to serve as the provider of life insurance
and health insurance and/or administrative services relating thereto for those
of the Seller's employee benefit plans that are currently insured or serviced by
the Seller (excluding long term care services), which contract shall contain the
performance standards set forth in Schedule 8.10. Seller represents and
covenants to Buyer that the performance standards set forth on such Schedule
8.10 represent the performance standards presently being complied with or
exceeded by Seller in connection with its servicing of Seller's employee benefit
plans and will be complied with or exceeded by Seller as of the Effective Time.
Seller and Buyer shall work together in good faith prior to the Closing to set
rates for such insurance and benefits that will permit Buyer to maintain a level
of profitability on a per member basis and permit Seller to establish a level of
expenses payable to the Buyer on a per member basis that are substantially
equivalent to the level of profitability and expenses currently earned and
sustained by Seller with respect thereto. At the end of this period, both Seller
and Buyer agree to negotiate, in good faith, regarding additional periods of
coverage for Seller's employees.


                                   ARTICLE IX

                               CERTAIN TAX MATTERS

                  Seller and Buyer hereby covenant and agree with respect to
certain tax matters as follows:

                  Section 9.1 Section 338(h)(10) Election.

                  (a) With respect to the acquisition of the GBO Subsidiaries
Shares hereunder, (i) Buyer shall make a timely election under Section 338(g) of
the Code and any corresponding elections under state and local tax laws with
respect to the acquisition hereunder of such GBO Subsidiaries Shares, and Seller
and Buyer shall jointly make a timely election under Section 338(h)(10) of the
Code and any corresponding elections under state and local tax laws
(collectively, the "Election") with respect to such acquisition, (ii) Seller and
Buyer shall, as promptly as practicable following the Closing Date, cooperate
with each other to take all actions necessary and appropriate (including filing
such forms, returns, elections, schedules and other documents as may be
required) to effect and preserve a timely Election in accordance with Section
338 of the Code or any successor provisions (and all corresponding state and
local tax laws) and (iii) Seller and Buyer shall report the sale and acquisition
of the GBO Subsidiaries Shares pursuant to this Agreement consistent with the
Election.

                  (b) In connection with the Election, within sixty (60) days of
Closing, Seller shall provide to Buyer a schedule which sets forth the tentative
allocation (the "Tentative Allocations Schedule") of the Purchase Price (i)
between the Assets other than the GBO Subsidiaries Shares and the GBO
Subsidiaries Shares and (ii) a further allocation of the amount assigned to the
GBO Subsidiaries Shares among the assets held by the GBO Subsidiaries in a
manner that is consistent with the preliminary estimated Modified Aggregate
Deemed Sales Price and the Adjusted Gross-Up Basis resulting from the Election.
Buyer and Seller acknowledge that the allocations contained in the Tentative
Allocations Schedule will be revised to reflect the actual Purchase Price, which
allocations shall take into account the post-closing adjustment to the Purchase
Price pursuant to Section 1.5 hereof. As soon as practicable, but no later than
30 days after the Closing GAAP Balance Sheet becomes final pursuant to Section
1.5, Seller shall provide to Buyer a final revised allocation (the "Final
Allocations Schedule") of the amounts allocated in the Tentative Allocation
Schedule. Such allocations shall be made in accordance with 


                                       36
<PAGE>   43
Section 338(b) and Section 338(h)(10) of the Code and any applicable Treasury
Regulations, provided, however, that Buyer will be entitled to add its
transaction costs to the Adjusted Grossed- Up Basis of the GBO Subsidiaries
Shares for purposes of allocating such Adjusted Grossed-Up Basis among the GBO
Included Assets held by the GBO Subsidiaries, and Seller will be entitled to
take into account its transaction costs when calculating its gain or loss from
the sale of the Assets. Buyer shall have the right to review the Final
Allocation Schedule, and Seller and Buyer shall consult and resolve in good
faith any issues arising as a result of Buyer's review of such schedule. If the
parties accept the Final Allocation Schedule, it shall be final and binding on
the parties. However, if the parties are unable to resolve any dispute within
fifteen (15) Business Days of the receipt by Buyer or Seller of the Final
Allocation Schedule, the parties shall jointly request Coopers & Lybrand, or
other independent accountants agreed by the parties, to resolve any issue in
dispute as promptly as possible, with one-half of the costs of such resolution
to be borne by each of Seller and Buyer. The determination made by such
independent accountants shall be final and binding upon the parties hereto. If
such independent accountants are unable to make a determination with respect to
any dispute prior to the due date for the filing of any Tax Return for which
such determination is necessary, Buyer and Seller shall file such Tax Return
without such determination having been made, subject, however, to the parties'
obligation thereafter to file amended Tax Returns reflecting the final decision
of the independent accountants.

                  Section 9.2  Returns; Indemnification; Liability for Taxes.

                  (a) Seller shall prepare and file (or cause to be prepared and
filed) on a timely basis all Tax Returns with respect to the GBO Subsidiaries
for all taxable periods ending on or before the Closing Date ("Seller Tax
Returns") and shall pay, and shall indemnify and hold Buyer harmless against and
from (i) all Taxes of the GBO Subsidiaries for all taxable years or periods
which end on or before the Closing Date; (ii) all Taxes for all taxable years or
periods of all members (other than the GBO Subsidiaries) of any affiliated group
of which the GBO Subsidiaries is or has been a member prior to the Closing Date;
and (iii) with respect to any taxable period commencing before the Closing Date
and ending after the Closing Date (a "Straddle Period") all Taxes of the GBO
Subsidiaries attributable to the portion of the Straddle Period prior to and
including the Closing Date (the "Pre-closing Period"). For purposes of this
Agreement, the portion of any Tax that is attributable to the Pre-closing Period
shall be (i) in the case of a Tax that is not based on net income, gross income,
premiums or gross receipts, the total amount of such Tax for the period in
question multiplied by a fraction, the numerator of which is the number of days
in the Pre-closing Period, and the denominator of which is the total number of
days in such Straddle Period, and (ii) in the case of a Tax that is based on any
of net income, gross income, premiums or gross receipts, the Tax that would be
due with respect to the Pre-closing Period if such Pre-closing Period were a
separate taxable period, except that exemptions, allowances, deductions or
credits that are calculated on an annual basis (such as the deduction for
depreciation or capital allowances) shall be apportioned on a per diem basis.
For purposes hereof, all Taxes which are the subject of this Article IX arising
out of the transaction contemplated by Article I hereof, including Taxes
resulting from the Election, shall be deemed to be Taxes attributable to the
Pre-closing Period.

                  (b) Buyer shall prepare and file (or cause to be prepared and
filed) on a timely basis all Tax Returns of the GBO Subsidiaries relating to
periods ending after the Closing Date and shall pay, and, except as provided in
subsection (c) hereof, shall indemnify and hold Seller harmless against and from
(i) all Taxes of the GBO Subsidiaries for any taxable year or period commencing
after the Closing Date; and (ii) all Taxes of the GBO Subsidiaries for any
Straddle Period other than Taxes attributable to the Pre-closing Period.


                                       37
<PAGE>   44
                  (c) Notwithstanding any other provision of this Article IX,
Seller shall indemnify and hold Buyer and the GBO Subsidiaries harmless against
any guarantee fund assessment to the extent that it is based upon premiums
written prior to Closing.

                  (d) In the event that any refunds are paid or made available
by any Taxing Authority (or other Governmental Entity) that relate to any
guarantee fund assessment that was indemnified by Seller or any of its
Affiliates pursuant to Section 9.2(c) hereof, Buyer shall cause such refunds to
be repaid to Seller, in accordance with the provisions of Section 9.3(d) hereof.

                  (e) In the event that any guarantee fund assessment that was
indemnified by Seller or any of its Affiliates pursuant to Section 9.2(c) hereof
gives rise to a credit against any liability for Tax of Buyer or any Affiliate
of Buyer, Buyer shall cause the amount of such credit to be paid to Seller as
such credit becomes available to Buyer or any of its Affiliates to reduce any
such liability for Tax, in accordance with the provisions of Section 9.3(d)
hereof.

                  Section 9.3  Cooperation; Refunds and Credits.

                  (a) All refunds or credits of Taxes for or attributable to
taxable years or periods of the GBO Subsidiaries ending on or before the Closing
Date (or the Pre-closing Period, in the case of a Straddle Period) shall be for
the account of Seller; all other refunds or credits of Taxes for or attributable
to the GBO Subsidiaries shall be the account of Buyer. Following the Closing,
Buyer shall cause the GBO Subsidiaries to forward to Seller any such refunds or
credits due Seller pursuant to this Section 9.3(a) after receipt or realization
thereof by Buyer, and Seller shall forward (or cause to be forwarded) to Buyer
any refunds or credits due to Buyer pursuant to this Section 9.3(a) after
receipt or realization thereof by Seller, in each case in accordance with the
provisions of Section 9.3(d) hereof.

                  (b) If an audit examination of any Tax Return of Seller or its
Subsidiaries for any taxable period ending on or before the Closing Date shall
result (by settlement or otherwise) in any adjustment the effect of which is to
increase deductions, losses or tax credits or decrease income, gains, premiums,
revenues or recapture of tax credits ("Changes") reflected on a Tax Return of
Buyer, CCI and its Subsidiaries for any taxable period ending after the Closing
Date, Seller will notify Buyer and provide it with all necessary information so
that it can reflect on the appropriate Tax Return of Buyer any appropriate
Changes. If as a result of such Changes, Buyer or its Subsidiaries enjoy a net
Tax benefit from an increase in deductions, losses or tax credits and/or a
decrease in income, gains, premiums, revenues or recapture of tax credits
("Buyer Benefits") for taxable periods ending after the Closing Date, Buyer
shall pay to Seller the amount of such Buyer Benefit, as and when such Buyer
Benefits are realized by Buyer in accordance with Section 9.3(d) hereof.

                  (c) If an audit examination of any Tax Return of Buyer or its
Subsidiaries for taxable periods ending after the Closing Date shall result (by
settlement or otherwise) in any Change reflected on a Tax Return of Seller or
its Subsidiaries for any taxable periods ending on or before the Closing Date,
Buyer will notify Seller and provide it with all necessary information so that
Seller can reflect any appropriate Changes on its Tax Return. If as a result of
such Changes, Seller or its Subsidiaries enjoy a net Tax benefit from an
increase in deductions, losses or tax credits and/or a decrease in the income,
gains, premiums, revenues or recapture of tax credits ("Seller Benefits") for
taxable periods ending on or before the Closing Date, Seller shall pay to Buyer
the amount of such Seller Benefits as and when such Seller Benefits are realized
by Seller, in accordance with Section 9.3(d) hereof.

                  (d) Any payments of refunds or credits for Taxes, or any
payment of Buyer Benefits or Seller Benefits, that are required to be paid under
this Article IX hereof shall be made within ten (10) 


                                       38
<PAGE>   45
Business Days of the receipt of any refund or thirty (30) Business Days of the
realization of any tax benefit, as the case may be. Any payments not made within
such time period shall be subject to an interest charge of ten percent (10%) per
annum.

                  Section 9.4 Termination of Tax Sharing Agreements. Seller and
Buyer hereby agree and covenant that any obligation of or to GBO Subsidiaries
pursuant to any tax sharing agreement or any similar arrangement in effect at
the Closing Date shall be paid on or before the Closing Date and any further
obligations otherwise existing thereunder shall be extinguished on the Closing
Date.

                  Section 9.5  Conduct of Audits and Other Procedural Matters.

                  Each party shall, at its own expense, control any audit or
examination by any Taxing Authority, and have the right to initiate any claim
for refund or amended return, and contest, resolve and defend against any
assessment, notice of deficiency or other adjustment or proposed adjustment of
Taxes ("Proceedings") for any taxable period for which that party is charged
with payment or indemnification responsibility under this Agreement. Each party
shall promptly forward to the other in accordance with Section 15.3 copies of
all written notifications and other written communications, including if
available the original envelope showing any postmark, from any Taxing Authority
received by such party or its Affiliates relating to any liability for Taxes for
any taxable period for which such other party or any of its Affiliates is
charged with payment or indemnification responsibility under this Agreement and
each indemnifying party shall promptly notify, and consult with, each
indemnified party as to any action it proposes to take with respect to any
liability for Taxes for which it is required to indemnify another party and
shall not enter into any closing agreement or final settlement with any Taxing
Authority with respect to any such liability without the written consent of the
indemnified parties, which consent shall not be unreasonably withheld. In the
case of any Proceedings relating to any Straddle Period, Buyer shall control
such Proceedings and shall consult in good faith with Seller as to the conduct
of such Proceedings. Seller shall reimburse Buyer for such portion of the costs,
including legal costs, of conducting such Proceedings as is represented by the
portion of the Tax with respect to such Straddle Period for which Buyer is
liable pursuant to Section 9.2 hereof. Each party shall, at the expense of the
requesting party, execute or cause to be executed any powers of attorney or
other documents reasonably requested by such requesting party to enable it to
take any and all actions such party reasonably requests with respect to any
Proceedings which the requesting party controls. The failure by a party to
provide timely notice under this Section 9.5 shall relieve the other party from
its obligations under this Article IX with respect to the subject matter of any
notification not timely forwarded, to the extent the other party has suffered a
loss or other economic detriment because of such failure to provide notification
in a timely fashion.

                  Section 9.6 Resolution of Disagreements Among Parties. If
Seller and Buyer disagree as to the matters governed by this Article IX, Seller
and Buyer shall promptly consult with each other in an effort to resolve such
dispute. If any such disagreement cannot be resolved within twenty (20) Business
Days of the date of initial consultation, Seller and Buyer shall jointly request
such independent accountants as shall be mutually agreed by the parties, to
resolve any issue in dispute as promptly as possible, with one-half of the costs
of such resolution to be borne by each of Buyer and Seller. The determination
made by such accountants shall be final and binding upon the parties hereto.

                  (a) Buyer or Unicare will make an offer of employment to each
employee of the GBO Included Business who is an "active employee" as of the
Effective Time; provided that Buyer may terminate at any time following the
Closing Date the employment of any employee who accepts such offer and may
change or alter the terms of such employment at any time following the Closing
Date. For purposes of this Agreement, the term "active employee" shall mean any
Person who, at the Effective Time, is actively employed by Seller in the GBO
Included Business (including, without limitation, part-time employees) or who is
on short-term disability leave, personal unpaid leave or family medical leave,
as of the Effective Time (such employees on short-term disability, personal
unpaid leave or family medical leave shall be offered employment by Buyer as of
the date they return to active employment provided that Buyer shall not be
responsible for holding more than fifty-five (55) positions open for persons on
short-term disability, personal unpaid leave or family medical leave as of the
Effective Time), but shall exclude all other Persons. Any such offers of
employment with Buyer shall generally be on the terms and conditions as
described in this Agreement; provided, however, that Buyer will be permitted to
make appropriate adjustments and modifications to such terms and conditions in
the instances where in good faith it believes such adjustment or modification
shall be necessary in order to integrate such employees into the existing Buyer
workforce and management structure; and provided further that Buyer shall not be
required to offer any post-retirement medical or health benefits to such
employees. Notwithstanding anything contained in this Section 10.1(a) to the
contrary, Buyer's offer of employment shall include compensation for such
employees at the same base salary as received by such employees as of the
Effective Time and such employees shall have the same responsibilities and title
(except as otherwise previously disclosed to Seller) as they had with Seller as
of the Effective Time. Each Transferring Employee's vacation days available in
1997 shall be at least equal to the number of days that would have been
available for 1996 if the Transferring Employee were employed by the Buyer for
the full year, counting all of the Transferring Employee's service with Seller
as service for the Buyer. Buyer shall recognize all service with Seller of those
employees of the GBO Included Business who accept employment with Buyer (a
"Transferring Employee") for purposes of vesting and eligibility to participate
in Buyer's vacation, pension, 401(k), severance (which will become effective 180
days after the Effective Time) and sick pay programs and for vesting purposes
under Buyer's pension plan. The pre-existing condition requirements of Buyer's
medical benefit plans and the evidence of insurability requirements of Buyer's
group term life insurance program shall be waived for Transferring Employees.
The parties agree to cooperate in the period prior to Closing with respect to
employment transition matters that may arise and with respect to issues that may
arise in connection with such transition under the WARN Act.

                  Buyer and Seller agree that assets (including any outstanding
loans) equal to all of the account balances of the Transferring Employees
(except for Transferring Employees who are eligible for retirement under
Seller's Pension Plans and who elect not to have their account balances
transferred) in any Seller defined contribution pension plan will be
transferred, in trustee-to-trustee transfer, to Buyer's 401(k) plan pursuant to
applicable law. Buyer's 401(k) plan shall accept such transfers which shall
occur as soon as reasonably possible subsequent to the contribution of Seller's
profit sharing contribution to its defined contribution pension plan for the
1996 calendar year. Buyer has provided Seller with a copy of the most recent
favorable determination letter issued by the Internal Revenue Service with
respect to Buyer's 401(k) plan and Buyer represents that nothing has occurred on
or prior to the transfers described in this Section 10.1 which will cause
Buyer's 401(k) plan to fail to be tax-qualified. Buyer and Seller 


                                       40
<PAGE>   47
shall cooperate in making, and shall make, all the appropriate filings required
under the Code and ERISA, and the regulations thereunder, and shall further
cooperate to ensure that the transfers described in this Section 10.1 satisfy
the applicable requirements of Sections 401(k), 414(l) and 401(a)(12) of the
Code and the regulations thereunder.

                  (b) Seller has adopted the modifications to its severance plan
in the manner previously disclosed to Buyer.

                  (c) Buyer shall reimburse Seller for one-half of any severance
costs (cash compensation and costs for payroll taxes, 401(k) plan contributions,
pensions and group health and life insurance ("Additional Benefit Costs") under
Seller's modified severance plan (a copy of which has been provided to Buyer)
that Seller may be required to pay to any employee of the GBO Included Business
who is offered employment by Buyer (or one of its Affiliates) at the time of
Closing, but who elects not to accept such offer and whose employment with
Seller terminates; provided, however, that Buyer's reimbursement obligation
pursuant to this subsection (c) shall not exceed $3,000,000 in the aggregate if
Buyer relocates employees at the Berkeley Headquarters Building to a location
within the Interstate 495 loop and Buyer provides to such relocated employees a
reasonable commute assistance program. There shall be no limitation on Buyer's
reimbursement obligation under this Section 10.1(c) if Buyer (i) relocates
employees at the Berkeley Headquarters Building to a location outside a 20-mile
radius from the Berkeley Headquarters Building and does not provide such a
reasonable commute assistance program, or (ii) relocates outside the area
bounded by the Interstate 495 loop corridor.

                  (d) Buyer shall reimburse Seller for three-quarters of any
severance costs (cash compensation and Additional Benefit Costs) that Seller may
be required to pay to any employee of the GBO Included Business who accepts
Buyer's offer of employment at the time of Closing but whose employment with
Buyer (or one of its Affiliates) is terminated without cause within six (6)
months after the Effective Time.

                  (e) Buyer shall reimburse Seller for amounts up to a maximum
of $5,000,000 that Seller may be required to pay or incur (including any
Additional Benefit Costs) with respect to payments to GBO Division Employees
under Seller's retention bonus plan (a copy of which has been furnished to
Buyer). With respect to payments to be made under pension plans attributable to
such retention bonus plan, Buyer shall pay Seller a lump sum payment equal to
the net present value of such future pension plan payments computed using a
discount rate equal to 7.5%. Such reimbursements or payments shall be made by
Buyer to Seller within five (5) Business Days after Buyer has received from
Seller a request for such reimbursement or payments together with such
information relating to the payments for which reimbursement or payments is
requested as shall be reasonably requested by Buyer.

                  (f) Except as set forth in this Section 10.1, Buyer shall have
no liability to any employee or any former employee of Seller or the GBO
Included Business or to Seller by reason of the past employment by Seller or its
affiliated company or by reason of any benefit plan including any severance or
disability plan for any of such employees and any retirement or post retirement
benefit plan of Seller; and Seller will indemnify and hold harmless Buyer
against any claim or Liability to any such employee by reason of such employment
or any such benefit arising by reason of service (or termination of service) at
any time up to and including the Closing Date. Except as expressly above
provided in this Section 10.1, it is the intention of the parties that all
accrued vacation of the Transferring Employees be paid on or prior to the
Closing Date by Seller and that bonus and other benefit amounts of the
Transferring Employees be paid when due by Seller. Seller shall have no
liability with respect to any Transferring Employee under an employee benefit
plan maintained by Buyer or any Affiliate of Buyer 


                                       41
<PAGE>   48
and Buyer will indemnify and hold harmless Seller against any claim or Liability
to any employee of Buyer (including Transferring Employees) with respect to such
employee benefit plans.

                  (g) Nothing herein shall be construed to cause any person to
be deemed to be other than an "at will" employee.


                                   ARTICLE XI

                       CONDITIONS TO OBLIGATIONS OF BUYER

                  The obligation of Buyer to consummate the transactions
contemplated by this Agreement at the Closing is subject to the satisfaction by
Seller or waiver by Buyer of the following conditions on or before the Closing
Date:

                  Section 11.1 Representations and Warranties Correct. All of
Seller's representations and warranties shall be true and correct in all
material respects on the date hereof and on the Closing Date as if made on such
date and the aggregate effect of all inaccuracies in Seller's representations
and warranties contained herein as of the date hereof shall not have had a
Material Adverse Effect (for this purpose treating each such representation
which has a Material Adverse Effect qualification as if it did not have such a
qualification). Buyer shall have received from appropriate officers of Seller a
certificate or certificates to such effect, in form and substance reasonably
satisfactory to Buyer.

                  Section 11.2 Performance; No Default. Seller shall have
performed and complied in all material respects with all the material
obligations, agreements and conditions required by this Agreement to be
performed or complied with by it at or prior to the Closing and Buyer shall have
received from appropriate officers of Seller a certificate or certificates to
such effect, in form and substance reasonably satisfactory to Buyer.

                  Section 11.3 Absence of Injunction. There shall be no order or
decree entered in any action or proceeding before a Governmental Entity of
competent jurisdiction restraining, enjoining or prohibiting the consummation of
this Agreement or the transactions contemplated hereby.

permits and licenses (including any third party administrator and utilization
review authority) of Governmental Entities contemplated by Sections 2.7 and 3.3
shall have been obtained, or waiting periods referenced therein shall have
expired without adverse action, and no Governmental Entity having jurisdiction
over the business of Buyer shall have imposed any materially burdensome new
condition on Buyer. For purposes hereof, the imposition of a requirement to
maintain total adjusted capital at a level higher than 150% of "Company action
level" risk based capital by the Delaware Department, or the imposition of the
Delaware Department of other restrictions on ordinary dividends so long as such
total adjusted capital level is met, shall be considered materially burdensome.
Notwithstanding the provisions of the first sentence hereof, if notwithstanding
compliance with the terms of Section 7.1, any required relicensure contemplated
by Section 2.7(ii) has not been obtained prior to the Effective Time, such
failure to obtain relicensure shall not constitute a failure to satisfy the
condition set forth in this Section 11.4 unless such failure would have a
Material Adverse Effect with respect to the GBO Business.

                  Section 11.5 Consents. The consents and approvals of third
parties (other than Governmental Entities) set forth on Schedule 11.5 shall have
been obtained, and such consents and approvals shall not impose upon the Buyer
or the GBO Included Business any conditions or other 


                                       42
<PAGE>   49
requirements which would (i) cause the Buyer or the GBO Included Business any
material additional costs or (ii) materially interfere with the continued
operations of the GBO Included Business as it is presently conducted.

                  Section 11.6 Intercompany Accounts. Except as otherwise
provided in Section 5.10 hereof, there shall be no intercompany obligation of

Balance Sheet.

connection with the sale and delivery by Seller of the GBO Subsidiaries Shares
and the sale, assignment, transfer and conveyance of the GBO Included Assets, or
the execution, delivery and performance of contracts or agreements pursuant to
or contemplated by this Agreement and shall have caused all appropriate stock
transfer tax stamps to be affixed to the certificate or certificates
representing the GBO Subsidiaries Shares so sold and delivered.

                  Section 11.8 No Material Adverse Effect. No event shall have
occurred which shall have resulted or is reasonably likely to result in a
Material Adverse Effect with respect to the GBO Included Business; provided,
however, that the failure to obtain consent to the assignment of any or all GBO
Included Contracts (other than those GBO Included Contracts listed on Schedule
11.5) shall not constitute a Material Adverse Effect.

                  Section 11.9 Resignation of Directors. The directors of each
of the GBO Subsidiaries shall have resigned effective as of the Closing.

                  Section 11.10 Other Transactional Agreements. The License
Agreement, Coinsurance Agreement, Administration Agreement, Assumption
Reinsurance Agreement, Lease Agreements, Lease Assignments, and Service
Agreement shall have been entered into at Closing.

received an opinion, dated the date of Closing, from Rogers & Wells, counsel to
the Seller, in form and substance reasonably satisfactory to Buyer.


                                   ARTICLE XII

Buyer's representations and warranties shall be true and correct in all material
respects on the date hereof and on the Closing Date as if made on such date, and
the aggregate effect of all inaccuracies in Buyer's representations and
warranties contained herein as of the date hereof shall not have had a Material
Adverse Effect (for this purpose treating each such representation which has a
Material Adverse Effect qualification as if it did not have such a
qualification). Seller shall have received from appropriate officers of Buyer a
certificate or certificates to such effect, in form and substance reasonably
satisfactory to Seller.

                  Section 12.5 No Material Adverse Effect. No event shall have

                  Section 14.1  Indemnification.

                  (a) Seller will indemnify, defend and hold harmless Buyer and

(individually and collectively "Buyer Indemnifiable Losses") relating to,
resulting from or arising out of any breach of any of the representations,
warranties, covenants or agreements of Seller contained in this Agreement;
provided, however, that Seller shall not have any Liability for such

(the "Separate Transaction Documents") unless the aggregate of all Buyer
Indemnifiable Losses for which Seller would, but for this proviso, be liable
exceeds on a cumulative basis an amount equal to $2,500,000, in which case
Seller's Liability shall be only for such excess, but no more than the amount of
the Purchase Price.

                  (b) Buyer will indemnify, defend and hold harmless Seller and
its Affiliates, and their respective directors, officers and employees from and
against any and all demands, actions, proceedings, suits (by any Person, entity

<PAGE>   53
                  (c) Except as set forth in subsection (i) below, this Article
XIV shall be the exclusive remedy for Buyer and Seller, as the case may be,
relating to, resulting from or arising out of any breach by the other party of
any of the representations, warranties, covenants or agreements of such other
party contained in this Agreement. Indemnification under the indemnification
provisions contained in the Separate Transaction Documents is to be determined
in accordance with the terms of such Separate Transaction Documents.

                  (d) For purposes of this Agreement, "Indemnity Payment" means
any amounts of Indemnifiable Losses required to be paid pursuant to this Section
14.1.

                  (e) For purposes of this Agreement, "Indemnitee" means any
Person entitled to indemnification under this Agreement.

                  (f) For purposes of this Agreement, "Indemnifying Party" means
any Person required to provide indemnification under this Agreement.

                  (g) All statements contained herein or in any Schedule hereto,
or in any certificate delivered at the Closing, will be deemed representations
and warranties within the meaning of this Article XIV.

                  (h) No claim for Indemnifiable Losses made hereunder with
respect to any representation or warranty shall be made after expiration of the
survival period relating thereto set forth in Section 15.9.

                  (i) Notwithstanding any provisions of this Article XIV to the
contrary, the provisions of Sections 1.2(b), 1.3, 2.19, 3.4, 5.12 and 8.8 shall
be separate from and in addition to the obligations of the Buyer under this
Article XIV.

                  Section 14.2  Defense of Third Party Claims.

                  (a) If an Indemnitee receives notice of the assertion or
commencement, as the case may be, of any claim, demand, action, proceeding or
suit by any Person (including, without limitation, any Governmental Entity) who
is not a party to this Agreement or who is not an Indemnitee hereunder against
such Indemnitee, with respect to which any Indemnifying Party is obligated to
provide indemnification under Section 14.1 of this Agreement (a "Third Party
Claim"), the Indemnitee will give the Indemnifying Party prompt written notice
thereof. Such notice will describe the Third Party Claim in reasonable detail,
will be accompanied by all notices and documents (including court papers)
received by the Indemnitee with respect thereto and will indicate the estimated
amount, if practicable, of the Indemnifiable Loss that has been or may be
sustained by the Indemnitee. The Indemnifying Party will have the right to
participate in or, by giving written notice to the Indemnitee, to elect to
assume, the defense of any Third Party Claim at the Indemnifying Party's own
expense and by the Indemnifying Party's own counsel (which counsel will be
reasonably satisfactory to the Indemnitee) and the Indemnitee will, to the
extent requested, cooperate in good faith in such defense; provided, however,
that the Indemnitee may at its own expense retain separate counsel to
participate in such defense, it being understood, however, that if the
Indemnitee so chooses to participate in the defense, the Indemnifying Party
nevertheless shall be entitled to control the defense. The cooperation referred
to in the preceding sentence shall include the retention and (upon the
Indemnifying Party's reasonable request) the provision to the Indemnifying Party
of records and information which are reasonably relevant to such Third Party
Claim, and making employees available on a mutually convenient basis to provide
additional information and explanation of any material provided hereunder and
for testimony.

                  (b) If an Indemnitee is given written notice from the
Indemnifying Party that such Indemnifying Party has elected to assume the
defense of any Third Party Claim, the Indemnifying Party will not be liable for
any legal expenses incurred by the Indemnitee after such notice is given in
connection with the defense thereof and the assumption of such defense by the
Indemnified Party; provided, however, that if the Indemnifying Party fails to
assume the defense of such Third Party Claim within thirty (30) calendar days
after receiving notice from the Indemnitee that the Indemnitee believes the
Indemnifying Party has failed to take such steps, the Indemnitee may assume its
own defense, and the Indemnifying Party will be liable for any reasonable
expenses therefor. Notwithstanding anything contained herein to the contrary,
the Indemnitee will have the right to employ separate counsel at the
Indemnifying Party's expense and to control its own defense of such action or
proceeding if the named parties to any such suit, action or proceeding include
both the Indemnifying Party and the Indemnitee and if representation of both
parties by the same counsel would be inappropriate because, in the reasonable
opinion of counsel to the Indemnitee, (i) there are or may be legal defenses
available to the Indemnitee that are different from or additional to those
available to the Indemnifying Party, or (ii) a conflict or potential conflict
exists between the Indemnifying Party and the Indemnitee; provided, however,
that the Indemnifying Party shall not, in connection with any one action or
separate but substantially similar or related actions in the same jurisdiction
arising out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate counsel (in addition to
any local counsel) for all such Indemnities.

                  In the event that any Indemnifying Party does not elect to
assume the defense of any Third Party Claim in accordance with this Section
14.2, such Indemnifying Party will be obligated as provided in this Section 14.2
for all costs of defense of the Indemnitee.

                  The Indemnitee shall not knowingly or intentionally admit any
liability with respect to, or settle, compromise or discharge any Third Party
Claim prior to expiration of the 30-day period provided in the first paragraph
of this Section 14.2(b). If the Indemnifying Party shall elect not to assume the
defense of a Third Party Claim, the Indemnitee nevertheless will not enter into
a settlement, compromise or discharge of such claim without the consent of the
Indemnifying Party, which consent will not be unreasonably withheld. Without
obtaining a complete and unconditional release of the Indemnitee from any
further liability in respect of a Third Party Claim, the Indemnifying Party will
not enter into any settlement, compromise or discharge of such Claim without the
consent of the Indemnitee, which consent will not be unreasonably withheld.

                  (c) A failure to give timely notice as provided in this
Section 14.2 will not affect the rights or obligations of any party hereunder
except as provided in Section 14.1(g) and except and only to the extent that, as
a result of such failure, any party which was entitled to receive such notice
was deprived of its right to recover any payment under its applicable insurance
coverage or was adversely affected in its ability to defend a claim or there was
an increase in the amount of the Indemnifiable Losses which such party is
obligated to pay hereunder or such party was otherwise actually prejudiced as a
result of such failure.

                  (d) Upon making any Indemnity Payment, the Indemnifying Party
will, to the extent of such Indemnity Payment, be subrogated to all rights of
the Indemnitee against any third party in respect of the Indemnifiable Loss to
which the Indemnity Payment relates; provided, however, that until the
Indemnitee recovers full payment of its Indemnifiable Loss, any and all claims
of the Indemnifying Party against any such third party on account of said
Indemnity Payment are hereby made expressly subordinated and subjected in right
of payment to the Indemnitee's rights against such third party. Without limiting
the generality of any other provision hereof, each such Indemnitee and
Indemnifying 


                                       48
<PAGE>   55
Party will duly execute upon request all instruments reasonably necessary to
evidence and perfect the above-described subrogation and subordination rights.

                  Section 14.3 Direct Claims. In the event of any Indemnitee
should have a claim under this Article XIV against any Indemnifying Party that
does not involve a Third Party Claim (a "Direct Claim"), the Indemnitee shall
deliver a written notification of an Indemnifiable Loss under this Article XIV
specifying the nature of and basis for such claim, together with the amount or,
if not then reasonably ascertainable, the estimated amount, determined in good
faith, of such Indemnifiable Loss (an "Indemnity Notice") with reasonable
promptness to the Indemnifying Party and, in any event, within the time period
referred to in Section 14.1(g). So long as Indemnitee provides the Indemnity
Notice within the time period referred to in Section 14.1(g), the failure by any
Indemnitee to give the Indemnifying Notice shall not impair such party's rights
hereunder except to the extent that an Indemnifying Party demonstrates that it
has been irreparably prejudiced thereby or if the Indemnity Notice is not given.
If the Indemnifying Party notifies the Indemnitee that it does not dispute the
Indemnifiable Loss described in such Indemnity Notice or fails to notify the
Indemnitee within thirty (30) calendar days following receipt by an Indemnifying
party of an Indemnity Notice whether the Indemnifying Party disputes the
Indemnifiable Loss described in such Indemnity Notice, the Indemnifiable Loss in
the amount specified in the Indemnity Notice will be conclusively deemed a
liability of the Indemnifying Party under Article XIV and the Indemnifying Party
shall pay the amount of such Indemnifiable Loss to the Indemnitee on demand. If
the Indemnifying Party has timely disputed its liability with respect to such
Indemnifiable Loss, the Indemnifying Party and the Indemnitee will proceed in
good faith to negotiate a resolution of such dispute, and if not resolved
through negotiations within the period ending sixty (60) calendar days following
receipt by the Indemnifying Party of the Indemnity Notice, such dispute shall be
resolved by a court of competent jurisdiction.


                                   ARTICLE XV

                                   ARBITRATION

the insurance and reinsurance industry in reaching their decision.

                  Section 15.2 Initiation of Arbitration. To initiate
arbitration, a party shall send by certified mail, return receipt requested, to
the other party, at the address specified in Section 16.3 hereof, a notice
demanding arbitration.

                  Section 15.3 Appointment of Arbitrators. A panel of three (3)
arbitrators will decide any dispute or difference between the parties. All
arbitrators must be (a) disinterested officers or retired officers of life
insurance or life reinsurance companies other than the parties to this Agreement
or their Affiliates, or (b) disinterested persons of comparable experience. Each
of the parties agrees to appoint one of the arbitrators. In the event that
either party should fail to appoint its arbitrator within twenty (20) Business
Days following receipt of the notice demanding arbitration set forth in Section
15.2 hereof, the party demanding such arbitration may appoint the second
arbitrator before entering upon arbitration. The two party-appointed arbitrators
shall select a third arbitrator. In the event that the two party-appointed
arbitrators shall not be able to agree on the choice of the third arbitrator
within twenty (20) Business Days following their appointment, the parties may
agree on a third arbitrator within the next twenty (20) 


                                       49
<PAGE>   56
Business Days, and if they have not then so agreed, the Denver, Colorado office
of the American Arbitration Association shall, at the request of either party,
appoint as such third arbitrator a person who meets the qualifications specified
in the second sentence of this Section 15.3.

                  Section 15.4 Decision. The decision in writing by any two
arbitrators shall be final and binding on both of the parties. Judgment may be
entered upon a final decision of the arbitrators in any court of competent
jurisdiction. Arbitrators pursuant to this Article XV shall be governed by the
Federal Arbitration Act, Title 9, United States Code.

                  Section 15.5 Expenses of Arbitration. Each party shall bear
the expense of its own arbitrator (whether selected by that party, or by the
other party pursuant to the procedures set out in Section 15.3 hereof) and
related outside attorneys' fees, and shall jointly and equally bear with the
other party the expenses of the third arbitrator and of the arbitration.

                  Section 15.6 Location of Arbitration. Any arbitration
instituted pursuant to this Article shall be held in Denver, Colorado or at such
other location as the parties hereby shall agree.

                  Section 15.7 Survival of Article. This Article XV shall
survive termination of this Agreement.

                  Section 15.8 Other Actions. Submission of a matter to
arbitration shall be a condition precedent to any right to institute a
proceeding at law or in equity concerning such matter, except for injunctive or
other provisional relief pending the arbitration of a matter subject to
arbitration pursuant to this Reinsurance Agreement.


                                   ARTICLE XVI

                     MISCELLANEOUS PROVISIONS AND AGREEMENTS

delivery or disclosure may be necessary or appropriate (1) to effect compliance

restated on October 10, 1996.

                  Section 16.2 Expenses. Each party will bear its own expenses,

condition hereof and no consent provided for herein will be effective unless
evidenced by an instrument in writing duly executed by the proper party. This
Agreement (except for the provisions of Sections 3.4, 4.6, 15.1 and 15.2 which
will continue in effect) and the transactions contemplated hereby may be
terminated and abandoned at any time prior to the Closing Date (i) by mutual
written agreement of Buyer and Seller, (ii) by Buyer or Seller upon written
notice given to the other after entry of a restraining order or injunction
restraining or prohibiting the transactions contemplated by this Agreement and
the expiration or unfavorable disposition of all appeals related thereto, (iii)
by Buyer or Seller, upon ten (10) Business Days' written notice to the other, if
the Closing shall not have taken place by January 31, 1997 other than by reason
of a matter within the control of the party asserting such termination. In the

will have no liabilities pursuant to this Agreement to the other party hereto,

                  Section 16.5 Consent to Jurisdiction. Each of Buyer and Seller
irrevocably submits to the exclusive jurisdiction of (i) the Court of Chancery
of the State of Delaware and (ii) the United States District Court for the
District of Delaware, for the purposes of any suit, action or other proceeding
arising out of this Agreement or any transaction contemplated hereby. Each of

                                       52
<PAGE>   59
jurisdictional reasons, in the Chancery Court of the State of Delaware, New

document by hand delivery or U.S. registered mail in care of WellPoint Health

court. Each of Buyer and Seller irrevocably and unconditionally waives any
objection to the laying of venue of any action, suit or proceeding arising out
of this Agreement or the transactions contemplated hereby in (i) the Chancery
Court of the State of Delaware, New Castle County or (ii) the United States
District Court for the District of Delaware, and hereby further irrevocably and
unconditionally waives and agrees not to plead or claim in any such court that
any such action, suit or proceeding brought in any such court has been brought

                  Section 16.6 Assignment; Affiliate of Buyer. This Agreement
will be binding upon and inure to the benefit of the parties hereto and their
respective permitted successors (including, but not limited to, the surviving
company of any merger involving a party), legal representatives and assigns, but
this Agreement may not be assigned by either party without the written consent
of the other party; provided, however, that Buyer may assign this Agreement to
Unicare for purposes of causing Unicare to purchase the GBO Division Assets and
assume the GBO Division Liabilities, but such assignment shall not relieve Buyer
of ultimate liability under this Agreement if Unicare shall fail to perform the
obligations of Buyer hereunder.

                  Section 16.7 Entire Agreement. This Agreement, the Annexes and
Schedules attached hereto and the other agreements among the parties referred to
herein, contain the entire agreement among the parties hereto with respect to
the transactions contemplated hereby and supersede all previous written or oral
negotiations, commitments and writings. The section headings of this Agreement
are for convenience of reference only and do not form a part hereof and do not
in any way modify, interpret or construe the intentions of the parties. This
Agreement may be executed in two or more counterparts, and all such counterparts
will constitute one and the same instrument.

                  Section 16.8 Applicable Law. This Agreement will be governed
by and construed and enforced in accordance with the internal laws of the State
of Delaware applicable to agreements made and to be performed entirely within
such State, without regard to the conflicts of law principles of such State.

                  (a) The representations and warranties of Seller contained in

representations contained in Sections 2.13 and 2.20 shall survive until the
expiration of the relevant statute of limitations.

                  (b) The representations and warranties of Buyer contained in
Article III of this Agreement shall survive the Closing and shall terminate on
the second anniversary of the Closing; provided, however, that the

anniversary of the Closing.

                  Section 16.10 Further Assurances. Each of Seller and Buyer
will use its reasonable best efforts to do or cause to be done all things
necessary, proper or advisable to consummate the transactions contemplated by
this Agreement.

                  Section 16.11 Definition of "Knowledge." In each case in this
Agreement or in any Schedule hereto or in any certificate delivered pursuant
hereto in which a Person makes a representation or warranty based on the
"knowledge" or on what is "known" to such Person, such Person represents and
warrants only as to the knowledge of Executive Officers of such Person having
direct or indirect responsibility for the matter in question, including in the
case of any Subsidiary, the Executive Officers of such Subsidiary.

                  Section 16.12 Parties in Interest. Nothing in this Agreement
is intended to confer any rights or remedies under or by reason of this
Agreement on any Persons other than the parties hereto and their respective
successors and assignees. Nothing in this Agreement is intended to relieve or
discharge the obligations or liability of any third Persons to the parties
hereto. No provision of this Agreement shall give any third Persons any right of
subrogation or action over or against the parties hereto.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
duly executed by their respective officers thereunto duly authorized, as of the
day and year first above written.

respect to which any of the adverse effects described in the immediately
preceding sentence apply, together with a novation with respect to the Company

the Company shall give the Reinsurer at least ninety (90) days' prior notice of
its intention to cancel any such Third Party Reinsurance.

                  9.5 Allowance for Commissions and Expenses. The Reinsurer
shall assume liability for all Commissions, taxes and guaranty fund assessments
imposed on or with respect to premiums earned under the Coinsured Policies after

any

                                       20

allowances or amounts for liabilities for guaranty fund assessments or taxes
that arise from or relate to the Existing GBO Policies and are incurred during
the period ending with the Effective Time.

                  9.6 Experience Rating Refunds. The Reinsurer shall assume
liability for policyholder experience rating refunds with respect to the
Coinsured Policies relating to periods prior to the Effective Time. A dividend

Closing GAAP Balance Sheet.

                                   ARTICLE X.

                               DUTY OF COOPERATION

                  10.1 Duty of Cooperation. Each party hereto shall cooperate
fully with the other in all reasonable respects in order to accomplish the
objectives of, and consummate the transactions contemplated under, this
Coinsurance Agreement. This duty to cooperate shall include, but not be limited
to, making available any Coinsured Policy records which either party
subsequently may require to resolve issues related to claims or Reserves or
Liabilities.

                                   ARTICLE XI.

                            ACCOUNTING AND SETTLEMENT

                  11.1 Remittances. In connection with all balances under this
Coinsurance Agreement with respect to premiums and Benefits and other amounts
received or to be paid subsequent to the Effective Time, in accordance with the
Administration Agreement, the Company and the Reinsurer shall establish an
account with a bank or trust company with respect to which the Reinsurer shall
have the authority to make deposits and withdrawals. The Company shall have no
authority to make deposits or withdrawals with respect to such account. This
account shall be financed by the Reinsurer for the benefit of the Company and
the Reinsurer. Settlements by the Company to the Reinsurer or by the Reinsurer
to the Company are deemed to take effect as the Reinsurer makes withdrawals from
or deposits into such account. Interest and any other income accruing on this
account shall be retained by the Reinsurer for its own account.

                  11.2 Quarterly Report. Within thirty (30) Business Days after
the end of each Accounting Period, the Reinsurer, as 
<PAGE>   24
                                       21

service provider under the Administration Agreement, shall supply the Company
with a report that shall provide data which shall account for all funds flowing
through the account established pursuant to Section 11.1 during such Accounting
Period and the net amount due by the Company or the Reinsurer, as appropriate
under this Coinsurance Agreement at the end of such Accounting Period. The data
shall be prepared substantially in the form attached hereto as Exhibit A;
provided, however, that the parties may agree from time to time on the precise
format and data which must be supplied on Exhibit A.

                  11.3 Amounts Due Either Party. Any net amount due from the
Company to the Reinsurer at the end of any Accounting Period shall be paid no
later than ten (10) Business Days after the date on which the Quarterly Report
showing such net amount, as described in Section 11.2 hereof, is due. Any net
amount due from the Reinsurer to the Company shall be paid no later than ten
(10) Business Days following the receipt of such quarterly report from the
Reinsurer. If amounts due to be paid cannot be determined at such dates on an
exact basis, such payments may be determined on an estimated basis, with
adjustments made at the end of subsequent Accounting Periods for actual amounts
ultimately determined to be due.

                  11.4 Interest on Delayed Payments. Should any payment due to
either the Company or the Reinsurer be delayed, such delayed payment (including
any amount constituting a difference between an estimated and actual amount, as
described in Section 11.3 hereof) will accrue interest at the interest rate for
thirty (30) day United States Treasury bills as reported in The Wall Street
Journal as of the day on which any payment is due for the period that payment is
overdue.

                                  ARTICLE XII.

                             DURATION AND TERRITORY

                  12.1 Duration. This Coinsurance Agreement shall remain in full
force and effect for an unlimited time until all obligations hereunder have been
discharged or until the Company and the Reinsurer shall have agreed in writing
to a commutation or termination hereof.

                  12.2 Reinsurer's Liability. The Reinsurer's liability with
respect to any Coinsured Policy will terminate when the Company's liability
under the Coinsured Policy is terminated.
<PAGE>   25
                                       22

                  12.3 Territory. This Coinsurance Agreement shall apply to
Coinsured Policies covering lives and risks wherever resident or situated.

                                  ARTICLE XIII.

                                   INSOLVENCY

                  13.1 Payments by Reinsurer. The Reinsurer hereby agrees that,
as to all reinsurance made, ceded or otherwise becoming effective hereunder, the
reinsurance shall be payable by the Reinsurer on the basis of the liability of
the Company under the Coinsured Policies, without diminution because of the
insolvency, liquidation or rehabilitation of the Company or the appointment of a
conservator, receiver, liquidator or statutory successor of the Company,
directly to the Company or to its conservator, receiver, liquidator, or other
statutory successor.

                  13.2 Claims. It is agreed that the conservator, receiver,
liquidator or statutory successor of the Company shall give prompt written
notice to the Reinsurer of the pendency or submission of a claim under any
Coinsured Policies. During the pendency of such claim, the Reinsurer may
investigate such claim and interpose, at its own expense, in the proceeding
where such claim is to be adjudicated any defense available to the Company or
its conservator, receiver, liquidator or statutory successor. The expense thus
incurred by the Reinsurer is chargeable against the Company as a part of the
expense of insolvency, liquidation or rehabilitation to the extent of a
proportionate share of the benefit which accrues to the Company solely as a
result of the defense undertaken by the Reinsurer. If two or more assuming
reinsurers are involved in the same claim and a majority in interest elect to
interpose defenses to such claim, the expense shall be apportioned in accordance
with the terms of this Section 13.2 as though such expense had been incurred by
the Company.

                                  ARTICLE XIV.

                                   ARBITRATION

                  14.1 General. Any dispute or difference between the parties
with respect to the operation or interpretation of, or arising from or relating
to, this Coinsurance Agreement on which an amicable understanding cannot be
reached shall be decided by binding arbitration. Arbitration hereunder shall be
pursuant to

be on a first dollar basis and be without regard to the aggregate of all

termination of this Coinsurance Agreement.

                                  ARTICLE XVI.

other party. In no instance shall anyone other than the Company or the
Reinsurer, or their successors or permitted assigns, have any rights, benefits
or remedies under this Coinsurance Agreement. Until the Reinsurer has reinsured
a Coinsured Policy on an assumption reinsurance basis pursuant to the Assumption
Agreement, the Reinsurer shall not be liable to any insured, contract owner, or
beneficiary under any Coinsured Policy.

Agreement and any required governmental and regulatory consents and approvals,
the Company, if requested to do so by the Reinsurer, hereby agrees to cede to

                             ASSUMPTION CERTIFICATES

         3.1. Policyholder Notices. Upon the request of the Reinsurer to
reinsure, on an assumption basis, a Coinsured Policy pursuant to Section_2.1
hereof, and to the extent that the reinsurance of such Coinsured Policy is
permitted under applicable laws, rules or regulations or stated positions of
regulatory authorities, the Reinsurer shall prepare, with the cooperation of the
Company, a Policyholder notice, Certificate of Assumption and objection form,
and mail them to the Policyholder of such Coinsured Policy. Subject to
regulatory requirements of the various states, the Policyholder notices,
Certificates of Assumption and objection forms to be delivered to Policyholders
pursuant to this Section 3.1 shall be substantially in the forms attached hereto
as Exhibits A, B and C, respectively.

         3.2. Right to Object. Subject to regulatory requirements of the various
states, the Company and the Reinsurer agree that a Policyholder will be allowed
to remain a Policyholder of the Company if such Policyholder refuses to effect
the assumption of its Coinsured Policy in accordance with this Article III
during the applicable period set forth in the Policyholder notice, and all of
the rights and obligations of the Company and the Policyholder under such
Coinsured Policy and of the Company and the Reinsurer under the Coinsurance
Agreement with respect to such Coinsured Policy, shall remain the same.

         3.3. Novated Policies. In the event that a Coinsured Policy defined
herein as a Novated Policy is determined by applicable regulatory authorities or
by judicial decision (in either case, following the exhaustion of all rights of
appeal) not to have been novated, such Coinsured Policy shall, for all 

                                       9
<PAGE>   12
purposes of this Assumption Agreement, be deemed never to have been a Novated
Policy. Notwithstanding the foregoing, the fact that a Coinsurance Policy has
not been or cannot be assumed and novated by the Reinsurer pursuant to the terms
and conditions of this Assumption Agreement, for whatever reason, shall in no
event cause it not to be a Coinsured Policy under the Coinsurance Agreement.

         3.4. Direct Obligations. The Reinsurer shall be the successor to the
Company under the Novated Policies as if the Novated Policies were direct
obligations originally issued by the Reinsurer. The Reinsurer shall be
substituted in the place and stead of the Company, and each Policyholder,
insured or beneficiary under a Novated Policy shall disregard the Company as a
party thereto and treat the Reinsurer as if it had been originally obligated
thereunder. Such persons shall have the right to file claims or take other
actions under the Novated Policies on or after the effective date of such
novation directly with the Reinsurer, and shall have a direct right of action
for insurance liabilities reinsured thereunder against the Reinsurer, and the
Reinsurer hereby consents to be subject to direct action taken by any such
persons under a Novated Policy. The Reinsurer accepts and assumes the Novated
Policies subject to any and all defenses, setoffs and counterclaims to which the
Company would be entitled with respect to such insurance liabilities, it being
expressly understood and agreed by the parties hereto that no such defenses,
setoffs or counterclaims are waived by the execution of this Assumption
Agreement or the consummation of the transactions contemplated hereby and that
the Reinsurer shall be fully subrogated to all such defenses, setoffs and
counterclaims.

         3.5 Release of Company; Indemnity. Upon the consummation of the
assumption reinsurance of a Coinsured Policy from the Company to the Reinsurer
under this Assumption Agreement, the Company shall be released from any and all
liability with respect to such Coinsured Policy, except as may otherwise be
expressly set forth in the Transaction Documents. From and after the
consummation of the assumption reinsurance of a Coinsured Policy pursuant to
this Assumption Agreement, the Reinsurer shall assume and indemnify fully the
Company for any and all damages, costs and expenses, including reasonable
attorneys' fees and disbursements, arising out of, based upon or relating to
such Novated Policy, including, without limitation, liabilities for Extra
Contractual Obligations; provided, however, that the Reinsurer shall have no
obligation to indemnify the Company for any such damages, costs and expenses
arising out of, 
<PAGE>   13
based on or relating to any bad faith claims practices, willful misconduct,
fraud or gross negligence of the Company or its Affiliates (without attributing
to the Company or its Affiliates the actions of the Reinsurer or its
Affiliates).

with respect to the GBO Excluded Business Policies, and all profit, loss or
expense from the GBO Excluded Business shall be for the account of the Company.

         4.2 Company's Indemnification for GBO Excluded Business. The Company
hereby agrees on demand to indemnify and hold harmless the Reinsurer and its
Affiliates, and their respective officers, directors and employees from and
against any and all damages, costs and expenses, including reasonable attorneys'
fees and disbursements, arising out of, based upon or relating to the GBO
Excluded Business.

                                    ARTICLE V
                               GENERAL PROVISIONS

         5.1. Policy Administration. To the extent that such transfers have not
already taken place pursuant to the terms and conditions of the Administration
Agreement, the Company agrees to cooperate fully with the Reinsurer in the
transfer of all books, records, papers or any other documents relating to such
Novated Policies.

         5.2. Misunderstandings and Oversights. If any delay, omission, error or
failure to pay amounts due or to perform any other act required by this
Assumption Agreement is unintentional and caused by misunderstanding or
oversight, the Company and the Reinsurer will adjust the situation to what it
would have been had the misunderstanding or oversight not occurred. The party
first discovering such misunderstanding or oversight, or act resulting from the
misunderstanding or oversight, will notify the other party in writing promptly
upon discovery thereof, and the parties shall act to correct such
misunderstanding or oversight within thirty (30) Business Days of receipt of
such notice. However, this Section shall not be construed as a waiver by 

                                       11
<PAGE>   14
either party of its right to enforce strictly the terms of this Assumption
Agreement.

                    CONSIDERATION FOR ASSUMPTION REINSURANCE

         The consideration provided for in Article VIII of the Coinsurance
Agreement shall be the consideration for the assumption of the Novated Policies
(as direct obligations) by the Reinsurer, and there shall be no additional
consideration or premium due or payable under this Assumption Agreement.

                                   ARTICLE VII
                               DUTY OF COOPERATION

         Each party hereto shall cooperate fully with the other in all
reasonable respects in order to accomplish the objectives of this Assumption
Agreement. This duty to cooperate shall include obtaining the governmental and
regulatory consents and approvals and taking the other steps necessary for the
assumption of the Coinsured Policies, as described in Article III hereof. In
addition, this duty to cooperate shall include making available any Coinsured
Policy records which either party subsequently may require to resolve issues
related to claims or liabilities. The Company and the Reinsurer agree to perform
such additional acts and execute such additional documents and agreements as may
be necessary or desirable to carry out the purposes and objectives of this
Assumption Agreement; provided however, that the Reinsurer shall reimburse the

compete contained in Section 5.11 of the Purchase Agreement. Licensee's rights

         (b) In using the Names as provided in Section 2(a) above, Licensee
shall not use the Names in any manner which jeopardizes the significance,
distinctiveness, or validity thereof or impairs the value of the goodwill
associated therewith. Licensee shall permit Licensor's authorized
representative(s) to review

<PAGE>   6
         (b) This Agreement may be terminated by Licensor, at its option, upon

bearing the Names, and Licensee shall immediately change any trade name or d/b/a
to a name which does not include the Names (except with respect to words therein
other than "John Hancock" or a derivative thereof which are not distinctive to

Names or indicate that Licensee is a trademark licensee of Licensor. In
addition, after such termination, Licensee shall refrain from using or
displaying any advertising or promotional material or performing any other act
which would cause anyone to infer or believe Licensee to be licensee of Licensor
with respect to the Name Rights.

         (d) Termination of this Agreement shall not release either party from
any Liability incurred while this Agreement was in effect or which thereafter
may accrue in respect of any act or omission that occurred prior to termination,
nor shall termination affect in any way survival of this Section 4 or the
indemnification provisions of Section 3, and any other right or obligation
which, by its context, is intended to remain in effect after termination.

         (e) Upon termination of this Agreement, Licensee shall promptly perform
all reasonable acts which may be necessary to render effective the termination
of its interest in the Names including, but not limited to, the cancellation of
any registration or recordation of this Agreement or any summary thereof, and
Licensee shall execute any assignment, conveyance, acknowledgment, or other
document required or requested by Licensor relinquishing or conveying to
Licensor any and all rights to or interest in the Names which Licensee has or
may have acquired.

         (f) The rights and remedies set forth in this Section 4 are in addition
to all other rights and remedies available at law or equity.

     6.  Protection of Licensed Marks; Litigation.

         (a) Licensor and Licensee agree to notify each other promptly if either
party receives notice of (i) any conflicting uses of, or any applications of or
registrations for, a trademark or service mark that may conflict with the Names,
(ii) any acts of infringement or unfair competition involving the Names, or
(iii) any allegations that the use of the Names by Licensor or Licensee
infringes the trademark or service mark or other rights (including rights
relating to unfair competition) of any other person.

         (b) During the Term, Licensor will be obligated, and will have the sole
right, to take all reasonable steps to enforce the Name Rights, which shall
include the

                                       6.
<PAGE>   7
filing of opposition and cancellation proceedings before the United States
Patent and Trademark Office and state agencies responsible for registration of
trademarks and service marks but shall not include the obligation to initiate
unfair competition and trademark infringement litigation in the federal or state
courts. Licensor shall have the right to include Licensee as a party in such
litigation where necessary to maintain Licensor's standing, and Licensee agrees
to join in such litigation at Licensor's expense as a voluntary plaintiff or
claimant upon request of Licensor. Licensor shall have the sole right to control
and settle any opposition and cancellation proceedings and any infringement
proceedings that Licensor elects to initiate. Licensee shall cooperate with
Licensor in the prosecution of such litigation, opposition, or cancellation
proceedings, at Licensor's expense.

         (c) Any recovery obtained as a result of infringement shall be applied
first to reimburse the parties for their respective expenses (including costs
and attorney fees) incurred in connection with such suit or other proceeding and
any remaining recovery will be retained by Licensor.

Administration Agreement, it shall: (i) conduct itself in accordance with all
reasonable commercial and professional standards of care, diligence and good
faith which are substantially equal in quality to the standards the Company

industry generally, and shall generally act in such a way as to preserve
goodwill toward the Company on the part of the general public, customers, and
all those having business relations with the Company; (ii) comply with all
material laws, regulations and orders applicable to the Company with respect to

and (iv) with respect to the Administered Contracts, carry on its affairs in the
ordinary course of business and not make or institute any unusual method of

shall provide the Service Provider access to all of the Company's standards,
procedures, policies, operating guidelines, practices and instructions
(collectively, the "Standards"), which are in effect on the Effective Time, and

Contracts, and the Service Provider shall acknowledge receipt of such Standards;
provided, however, the parties hereby agree that after the Effective Time,
subject to the provisions of this Administration Agreement the Service Provider
may, adopt or reject, maintain, update, change or alter such Standards, if such
changes in the Standards are not inconsistent with prudent management practices
observed from time to time in the life and health insurance industry generally;
further provided, however, that for purposes of applying the foregoing standard,
the parties hereto agree to recognize the unique nature of the transactions
contemplated by this Administration Agreement and the other Transaction

         2.  (a) To the extent that the Company pays costs for which the Service
Provider is liable pursuant to this Article, the Service Provider shall
reimburse the Company for such amounts paid by the Company, net of any offset,
credit or return that directly reduces such costs. To the extent that the

obtains an offset, credit or return that directly reduces such costs, the
Company shall reimburse the Service Provider for such amounts if not previously
netted.

         (b) To the extent the Service Provider pays costs or expenses for which
the Company is liable pursuant to this Article, the Company shall reimburse the
Service Provider for such amounts paid by the Service Provider, net of any

Service Provider obtains an offset, credit or return that directly reduces such
costs, the Service Provider shall reimburse the Company for such amounts if not
previously netted. 

         (c) A party shall reimburse the other party within ten (10) Business
Days of the delivery of any request for reimbursement, together with any

H-15 (the "30-Day C.P. Rate") until the date of payment.

         E.  Premium Rate Formulas.

         The Service Provider shall provide the Company with its premium rate
formulas that are currently used to develop premium rates applicable to the
Coinsured Policies. The Service Provider shall have the right to propose and
implement changes to such premium rate formulas, subject to all required

submissions with respect to the changes to premium rate formulas under the

any necessary rate submissions prepared by the Service Provider with 

                                       12
<PAGE>   15
respect to permitted changes in premium rate formulas to the applicable state
insurance departments, on its own behalf, in accordance with state regulatory
requirements. The parties agree that the Company's right to disapprove any
proposed premium rate formula will be exercised only if such formula would be
violative of applicable laws or regulations, or would be grossly commercially
unreasonable or, with respect to a particular Existing GBO Policy form, would
represent a 15% or greater reduction in pricing.

         F. Financial, Statistical and Tax Services.

         1. To the extent applicable, the Service Provider shall use
commercially reasonable efforts to collect, administer and provide to the

         statement data (by statutory line of business; direct, acquired, ceded;
         by state, etc.) in accordance with both SAP and GAAP consistently
         applied, which are necessary to prepare the detailed supporting
         statutory exhibits and schedules; and 

     (d) provide reports to Third Party Reinsurers of Administered Contracts;

provided, however, that to the extent that the condition or sufficiency of the
financial, statistical, tax or other data provided to the Service Provider by
the Company under the Service Agreement causes circumstances that would
constitute a breach by the Service Provider of its obligations under this
Administration Agreement, the Service Provider will be deemed not to be in
default under this Administration Agreement. All information and data provided
by the Service Provider to the Company pursuant to this Article V.F. will be
provided in accordance with Annex A.

         2. The Service Provider will provide such other information relating to
the Coinsured Policies as may be reasonably requested from time to time by the
Company.

                                       13
<PAGE>   16
         3. Nothing herein shall be construed to require the Service Provider to
prepare any tax return, SAP filing or any other report required to be filed by
the Company. The Company shall be solely responsible for preparing and filing
such reports.

                                   ARTICLE VI

         B. Responses to Regulatory Authorities. The Company (with respect to
matters affecting its license and liability) or the Service Provider (with
respect to matters affecting its license and liability), as the case may be,
agrees to provide a prompt initial response to inquiries received from state
insurance departments or other governmental or regulatory authorities regarding
policyholder, contractholder, provider and consumer concerns or otherwise
arising out of or in connection with any activity or omission with respect to
the Administered Contracts which occurred prior to, on, or after the Effective

form and substance of such response or communication. The Company and the
Service Provider shall both have the right to participate in meetings and
conversations with such governmental or regulatory authorities to discuss such
inquiries. The Service Provider or the Company, as the case may be, will provide
the other party with all information necessary for such other party to conduct
whatever investigation is reasonable under the circumstances in order to respond
to such inquiries. Each party shall notify in writing the other of any such
inquiry within two (2) Business Days of receipt of such inquiry and provide
copies of all relevant documents related thereto. After such consultation and
cooperation, the Company shall have the right to control the resolution
(including entering into settlements) with respect to any inquiry that could
lead to the restriction or revocation of its license. The Service Provider shall
have the right to control the resolution (including entering into settlements)
with respect to any inquiry that could lead to the restriction or revocation of

agency's intention to commence any market conduct or similar examination or
review or to proceed with any administrative action, such as a hearing, fine,
penalty, license suspension or revocation or similar action, against the Service
Provider or the Company, which examination, review or administrative action
relates in any way to the Service Provider's performance under this
Administration Agreement or which otherwise relates solely to any of the
Administered Contracts. The Service Provider and the Company agree to cooperate
fully with each other and to use their reasonable good faith efforts in jointly
resolving any such issue or matter raised by a state insurance department or any
other government or regulatory department or agency.

         D. Cooperation. The Company and the Service Provider agree to cooperate
fully with each other and use their reasonable good faith efforts in dealing

authorities in maintaining the Administered Contracts in compliance in all
material respects with existing and future laws and regulations. If the Service
Provider determines that any of the Administered Contracts are materially not in
compliance with such laws and regulations, the Service Provider shall so notify
the Company. The Service Provider shall prepare and file any necessary
amendments to such Administered Contracts and other filings or documents
required and shall prepare any necessary filings for submission by the Company.

         E. Notice to Insureds. Where required by law, the Service Provider,
with the Company's cooperation, shall give written notice to insureds of the
identity of the Service Provider and the relationship between the Service
Provider, the Company and the insured. The Service Provider shall provide the

            A. Records and Access to Records.

         1. The Service Provider agrees to use commercially reasonable efforts
to perform all data processing activities and to keep and maintain identifiable,
orderly, accurate, complete and timely records and accounts of all business and
transactions pertaining thereto and Claims administered under this
Administration Agreement including complete underwriting and claims files;
provided, however, that to the extent that the condition or sufficiency of the
statistical data, books, records, accounts and files provided to the Service
Provider by the Company under this Administration Agreement or the Service
Agreement causes circumstances that would constitute a breach by the Service
Provider of its obligations under this Administration Agreement, the Service
Provider will be deemed not to be in default under this Administration
Agreement. The Service Provider agrees to keep such records and accounts
available at such locations as required by applicable state law. All books,
records and files established and maintained by the Service Provider by reason
of its performance under this Administration Agreement shall be subject to
examination at all reasonable times upon reasonable notice by the Company and
persons authorized by it or any governmental agency having jurisdiction over the
Company.

         2. The Company shall on the Closing Date, or as soon thereafter as is
practicable:

     (a) transfer to the Service Provider in a commercially reasonable manner
         and form the files, or copies thereof, owned by it that relate
         exclusively to each Administered Contract or, if not exclusively so
         relating, copies of those portions of such files applicable to each
         Administered Contract will be transferred to the Service Provider to
         the extent reasonable and practicable; and

     (b) if a file or portion thereof relating to an Administered Contract
         cannot be transferred or a copy cannot be provided to the Service
         Provider pursuant to Article IX B hereof, then it will be made
         available for inspection by the Service Provider.

     3.  (a) If the transfer of any files requires the 

                                       18
<PAGE>   21
     consent of any Person, the Company shall use commercially reasonable
     efforts to secure such consent on or prior to the date such transfer is to
     be made. Where such consent cannot be obtained, the Company shall not be
     required to transfer the applicable files to the Service Provider but shall
     provide copies of such files unless the absence of such consent prohibits
     providing copies, in which case the Company shall provide the Service
     Provider with access to such files. 

     (b) Nothing in this Article shall require the Company to transfer to the
     Service Provider any original files which the Company is required by any
     applicable laws or regulations or contractual obligations to retain,
     provided that the Company shall provide true and complete copies of such
     original files to the Service Provider.

         4. For so long as there are Administered Contracts issued or renewed by
the Company (or thereafter, if required by law or regulation or the provisions
of the applicable Administered Contract), the Service Provider shall retain all
files transferred by the Company or produced by the Service Provider on behalf
of the Company to the extent such files are required by applicable law or
regulation or the provisions of the applicable Administered Contract to be
retained by either the Service Provider or the Company.

         5. To the extent permitted or not prohibited by applicable law or
regulation, from the date hereof until the date on which the Company has
fulfilled all of its obligations to transfer files to the Service Provider under
this Administration Agreement, and at any time (without limitation) as may be
required in the Service Provider's reasonable judgment in order for the Service
Provider to comply with any law or regulation or to perform its obligations or
responsibilities under this Administration Agreement, the Service Provider and
its authorized representatives may from time to time reasonably request, and the
Company shall provide, at reasonable times during normal business hours, full
and open access to examine all such files to be transferred and all files under
the control of the Company pertaining to any of the Administered Contracts and
to the services to be provided 

                                       19
<PAGE>   22
by the Service Provider under this Administration Agreement and to discuss any
matters relating to any of the Administered Contracts and the services to be
provided by the Service Provider under this Administration Agreement with the
employees and agents of the Company who are knowledgeable therewith, so that the
Service Provider shall have sufficient opportunity to make whatever
investigation it shall deem necessary and desirable in connection with the
transactions contemplated by this Administration Agreement. Such access and
opportunity shall be exercised by the Service Provider and such authorized
representatives in a manner that shall not interfere unreasonably with the
operations of the Company. Such access shall include the right of the Service
Provider to make and retain copies of any files to the extent that the Service
Provider reasonably determines that it requires copies of such files in order to
carry out the transactions contemplated by this Administration Agreement or for
any legitimate business purpose related to this Administration Agreement.
Notwithstanding the first sentence of this subparagraph, no request by the
Service Provider shall diminish or otherwise affect any of the obligations or
responsibilities of the Company under this Administration Agreement.

         6. To the extent permitted or not prohibited by applicable law or
regulation, from the date hereof until the date on which the Service Provider
has fulfilled all its obligations to perform services for the Company under this
Administration Agreement, and at any time (without limitation) as may be
required in the reasonable judgment of the Company for the Company to comply
with any law or regulation or to perform its obligations or responsibilities
under this Administration Agreement, the Company and its authorized
representatives may from time to time reasonably request, and the Service
Provider shall provide, at reasonable times during normal business hours, full
and open access to examine the files of the Service Provider pertaining to any
of the Administered Contracts and to the services to be provided by the Service
Provider under this Administration Agreement (including, but not limited to, the
files transferred to the Service Provider pursuant to this Article and still
then retained by the Service Provider) and to discuss such services with the
employees and agents of the Service Provider who are knowledgeable therewith, so
that the Company shall have sufficient opportunity to make whatever
investigation it shall deem necessary and desirable in connection with the
transactions contemplated by this Administration Agreement. Such access and
opportunity shall be exercised by the 

                                       20
<PAGE>   23
Company and such representatives' in a manner that shall not interfere
unreasonably with the operations of the Service Provider. Such access shall
include the right of the Company to make and retain copies of any files to the
extent that the Company reasonably determines that it requires copies of such
files in order to carry out the transactions contemplated by this Administration
Agreement or for any legitimate business purpose contemplated by this
Administration Agreement. Notwithstanding the first sentence of this
subparagraph, no request by the Company shall diminish or otherwise affect any
of the obligations or responsibilities of the Service Provider under this
Administration Agreement.

         7. During the term of this Administration Agreement (or thereafter, if
required by law or regulation), the Service Provider shall retain all files
transferred by the Company or produced by the Service Provider on behalf of the
Company to the extent such files are required by applicable law or regulation or
the terms of an Administered Contract to be retained by either the Service
Provider or the Company and to the extent such files have not been transferred
to the Company. Any files which are not transferred to the Service Provider
shall be retained by the Company to the extent such files are required by
applicable law or regulation or the terms of an Administered Contract to be
retained by either the Service Provider or the Company.

         8. Each party hereto shall pay all storage and related expenses
associated with any files, and copies thereof, which it retains in its
possession.

            B. Ownership. All original files or suitable copies, which are
transferred to the Service Provider by the Company or produced by the Service
Provider for the benefit of the Company pursuant to this Administration
Agreement, shall be or remain the property of the Service Provider unless it is
otherwise required by applicable law or regulations that the Company retain
ownership. At such time as the Service Provider determines it is no longer
necessary under applicable law or regulation or the terms of an Administered
Contract to retain any file or copy thereof which is the property of the
Company, it may elect to return such file or copy thereof to the Company.
Notwithstanding anything herein to the contrary, the Service Provider shall have
the right 

                                       21
<PAGE>   24
to retain suitable copies of all files (originals and copies) transferred by the
Company to the Service Provider pursuant to this Administration Agreement.

         C. Audit. For so long as there are Coinsured Policies or ASO Contracts
issued or renewed by the Company, the Company may, at its own expense,
reasonably conduct (or have conducted on its behalf) an audit of the Service
Provider with respect to such files and other relevant documents in the
possession of the Service Provider upon reasonable written notice to the Service
Provider during normal business hours and solely for the purpose of:
(i) responding to or facilitating any regulatory investigation or inquiry, or
(ii) investigating or defending a Claim or a complaint by a third party against
the Company relating to an Administered Contract.

            A. Generally. Subject to the provisions of the Purchase Agreement,
neither the Company nor the Service Provider shall have the authority to
institute, prosecute or maintain any legal or regulatory proceedings on behalf
of the other party without the prior written consent of such other party, which
consent shall not be unreasonably withheld. Notwithstanding any other provision
of this Administration Agreement, no defense shall be interposed and no
settlement shall be entered into or agreed to by either party without the prior
written consent of the other party which consent shall not be unreasonably
withheld except that such party in its sole discretion may withhold consent, if
such defense or settlement could materially affect such party's licenses, its
relationship with any regulatory or governmental authority, or such party's
ability to conduct the GBO Included Business, or the Company's ability to
conduct the GBO Excluded Business.

         B. Notification. Each party shall promptly notify the other party of
any claim which may reasonably be expected to exceed $250,000 by reason of an

     such action reasonably requested by the Company (including without

     will reasonably cooperate with the Company, to facilitate the transition of
     the services to another service provider selected by the Company or to the
     Company.

transactions contemplated by the Purchase Agreement, the Coinsurance Agreement,
this Administration Agreement or for other good and valid business reasons
contemplated by such agreements, including but not limited to the obligations of
such other party to comply with applicable law or regulatory requirements or the
requirements of Administered Contracts. If a party has not requested return of
any file within one hundred eighty (180) days after the termination under

                                   ARTICLE XIV
                                   ARBITRATION

         A. General. Any dispute or difference between the parties with respect
to the operation or interpretation of, or arising from or relating to, this
Administration Agreement on which an amicable understanding cannot be reached
shall be decided by binding arbitration. Arbitration hereunder shall be pursuant
to and in accordance with the terms, conditions and procedures set forth in
Article XV of the Purchase Agreement.

                                   ARTICLE XV
                               GENERAL PROVISIONS

         A. Cooperation. The parties shall cooperate in a commercially
reasonable manner in order that the duties assumed by the Service Provider will
be effectively, efficiently and promptly discharged, and will not take any
actions which would frustrate the intent of the transactions contemplated by
this Administration Agreement, the Purchase Agreement or the Coinsurance
Agreement. Each party shall, at all reasonable times during normal business
hours under the circumstances, make available to the other party properly
authorized personnel for the purpose of consultation and decision. As soon as
practicable after the Effective Time, the Company shall make available to the
Service Provider copies of all policy forms and examples of all other forms,
including drafts and checks, used by the Company in its administration of the
Administered Contracts as reasonably requested by the Service Provider.

         B. Amendment; Waivers. This Administration Agreement may be amended or
modified, and any of the terms or conditions hereof may be waived, only by a
written instrument executed by the parties hereto, or in the case of a waiver,
by the party waiving compliance. Any waiver by any party of any condition, or of
the breach of any provision or term contained in this Administration Agreement,
in any one or more instances, shall not be deemed to be nor construed as a
further or continuing waiver of any such condition, or of the breach of any
other provision or term of this Administration Agreement. The failure of the
Company or the Service Provider to insist on strict compliance with this
Administration Agreement, or to exercise any right or remedy under this
Administration Agreement, shall not constitute a waiver of any rights provided
under this Administration Agreement, nor estop the parties from thereafter
demanding full and 

                                       28
<PAGE>   31
complete compliance nor prevent the parties from exercising such a right or
remedy in the future.

         C. Entire Agreement. Except as otherwise provided in the Purchase
Agreement and the Annexes and Schedules attached thereto, this Administration
Agreement, including all Annexes or Schedules attached hereto, and the other
Transaction Documents contain the entire understanding between the parties
hereto with respect to the transactions contemplated hereby and supersedes and
replaces all prior and contemporaneous agreements and understandings, oral or
written with regard to such transactions. All Annexes or Schedules delivered
pursuant to any provision hereof are expressly made a part of this Agreement as
fully as though completely set forth herein.

         D. Relationship. The Company and the Service Provider are and shall
remain independent contractors and not employees, agents or partners of the
other party. Except as expressly granted in this Administration Agreement or
otherwise by the other party in writing or as may be required by law or as
necessary to perform the services to be provided hereunder or to obtain the
benefits hereof, no party shall have any authority, express or implied, to act
as an agent of the other party or its subsidiaries or affiliates under this
Administration Agreement. Except as otherwise provided by any agreement between
the parties, the Service Provider shall be responsible for, and the Company
shall have no liability for, the payment of all employment, income and social
security taxes arising in connection with the compensation payable to the
Service Provider's personnel involved in the provision of the services
hereunder.

         E. Errors and Omissions. Any delays, errors or omissions on the part of
a party occurring in connection with this Administration Agreement or any
transaction hereunder shall not relieve any other party from any liability to
the first party which would have otherwise attached, had such delay, error or
omission not occurred, provided that such error or omission is rectified as soon
as reasonably practicable after discovery thereof.

         F. Best Efforts. No reference in this Administration Agreement to "best
efforts" or "commercially reasonable efforts" shall require a person obligated
to use its best or commercially reasonable efforts to incur substantial
out-of-pocket expenses, to 

                                       29
<PAGE>   32
incur indebtedness or, except as expressly provided herein, to institute
litigation or to consent generally to service of process in any jurisdiction.

         G. Governing Law. This Administration Agreement shall be deemed to have
been made under and governed by the laws of the State of Delaware without regard
to Delaware's choice of law rules.

         H. Invalidity. Unless the invalidity or unenforceability of any
provision or portion thereof frustrates the intent of the parties or the purpose
of this Administration Agreement, such invalidity or unenforceability shall not
affect the validity or enforceability of the other provisions or portions
thereof. In the event that such provision shall be declared unenforceable by a
court of competent jurisdiction, such provision or portion thereof, to the
extent declared unenforceable, shall be stricken. However, in the event any such
provision or portion thereof shall be declared unenforceable due to its scope,
breadth or duration, then it shall be modified to the scope, breadth or duration
permitted by law and shall continue to be fully enforceable as so modified
unless such modification frustrates the intent of the parties or the purpose of
this Administration Agreement.

         I. Counterparts. This Administration Agreement may be executed in
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         J. No Third Party Beneficiaries. Nothing in this Administration
Agreement is intended to confer any rights or remedies under or by reason of
this Administration Agreement on any persons other than the Company and the
Service Provider and their respective successors and assigns. Nothing in this
Administration Agreement is intended to relieve or discharge the obligations or
liability of any third persons to the Company or the Service Provider. No
provision of this Administration Agreement shall give any third persons any
right of subrogation or action over or against the Company or the Service
Provider.

         K. Assignment. The Service Provider may assign its rights and
obligations under this Administration Agreement to a wholly-owned subsidiary or
an Affiliate which is directly or indirectly wholly-owned by the Service
Provider's ultimate parent, after giving written notice of such assignment to
the Company, provided, however, that the Service Provider shall remain primarily
liable for any obligations which it assigns, delegates or 

                                       30
<PAGE>   33
out sources. Except as so permitted, neither party shall assign this
Administration Agreement or any rights or obligations hereunder without the
prior written consent of the other party hereto, and any such attempted
assignment without such prior written consent shall be void and of no force and
effect; provided, however, that no such assignment shall reduce or otherwise
vitiate any of the obligations of any other party hereunder. This Administration
Agreement shall inure to the benefit of and shall be binding upon the successors
and permitted assigns of the parties hereto.

         L. Headings. The headings in this Administration Agreement are for the
convenience of reference only and shall not affect its interpretation.

         M. Preparation. This Administration Agreement has been jointly prepared
by the parties hereto and the terms hereof will not be construed in favor of or
against any such party by reason of its participation in such preparation.

         N. Reasonableness. Each of the parties will act reasonably and in good
faith on all matters within the terms of this Administration Agreement.

         O. Notices. All notices, requests, demands, approvals and other

prior to the expiration of such 30-day period setting forth the anticipated time

<PAGE>   10


debts under any bankruptcy, rehabilitation, insolvency or other similar law now

undismissed and unstayed for a period of 60 days; or

                           (e) An order is entered by a court of competent

with Company, to facilitate the transition of the Services to another service
provider selected by Company or to Company.

                  13.2 Transfer of Information upon Termination of Services.
Upon termination of this Agreement, or any Service under this Agreement, at
Company's option and request, Service Provider shall promptly transfer all
Company information relating to the Services terminated (including but not
limited to, financial and technical information and data), in its existing
format, to Company or a party designated by Company. Such transfer shall be made
at Service Provider's expense, except that Company will reimburse Service
Provider for reasonable out-of-pocket expenses incurred by Service Provider and
agreed to in advance by Company in connection with such transfer.

                  13.3 Payment of Amounts Due. No termination of this Agreement,

                  15.1 Waiver. The failure of Service Provider or Company to
insist on strict compliance with this Agreement, or to exercise any right or

right or remedy in the future.

their respective legal successors or permitted assigns, any benefits or
remedies.

         charge of its application support services. If negotiation between such
         persons fails to resolve any such dispute to the satisfaction of both
         parties, then each party shall nominate one senior officer of the rank

                GBO BUSINESS REQUIREMENTS FOR SELLER ITS SERVICES

The GBO Business acquired by Buyer (hereinafter in this Attachment "GBO") and
the Seller's ITS Division ("ITS") agree to support objectives and conditions set
forth in this attachment.

The intent of this attachment is to:

         -        establish a support relationship between the parties; the
                  nature of which is likely to be dynamic rather than static due
                  to changes in business drivers for GBO and ITS.

         -        Ensure that business needs are properly met;

         -        clarify the service and support requirements and
                  responsibilities.

As a result of the constantly changing business requirements and technological
advances, this attachment will be reviewed on an annual basis to insure it
remains current.

1.       Architecture

         The GBO processing architecture for claims processing has two major
         components. They are on-line processing and batch processing. In
         addition there are a number of administrative systems, dominated by the
         billing and accounting system called CASS, which is client server
         system where the server is DB2 on the mainframe. Both are critical to
         the success and effectiveness of GBO's business.

         Batch Processing. The Batch processing system for the claims system
         begins at 7:30 p.m. E.S.T. each evening. As the claims system,
         Hanstar2, is a true on-line interactive update system, it is not
         necessary for the batch cycle to be completed before the on-line system
         is brought up for the next business day. There are a number of batch
         jobs that must be completed and these are prioritized to be done as
         early in the batch cycle as possible. The system completes the claim
         payment cycle through the production of checks/EOBs, daily accounting
         reports and feeds administrative reports.

         On-Line Processing. The on-line systems are separated into several
         distinct functions. The Hanstar2 claim payment system which provides
         support to all field claim offices across the country; the CASS system,
         which provides support for billing and accounting activities; and
         several other on-line systems that support pricing, dividends,
         contracts, association billing and administrative services.

         It will be incumbent upon the parties involved to ensure that the
         installed infrastructure is capable of supporting the architectural
         requirements of the business systems.

2.       Roles and Responsibilities

         ITS and GBO will designate individuals to be the focal points for
         interfacing on mainframe and midrange systems related issues. These
         individuals' responsibilities will include:

                  a.       Monthly meetings to review results and issues;

                  b.       Negotiating special requests;

                  c.       Resolving issues and establishing priorities for
                           staff assignments; and

                  d.       Problem escalation.

         ITS Technical Services. ITS Technical Services is responsible for
         creating and maintaining the technical infrastructure required to
         support the GBO environment. Technical Services will provide staffing
         to accommodate a workload projected to be equivalent to seven (7) full
         time systems programmers. This is consistent with previous support
         levels. Workloads and priorities will be determined and scheduled
         through the ITS Relationship Manager with input from the GBO
         Relationship Manager.

         TechLine. The TechLine is responsible for assisting the GBO Production
         Support teams with online and client/server environmental problems.
         Escalation procedures for problems are defined by communication from
         the problem source through GBO Help Desk operations staff, and up to
         the management of both ITS and GBO using existing procedures. The
         Relationship Managers will also be notified and it will be their
         responsibility to resolve any issues.

         With very few exceptions, the GBO Help Desk will be the primary contact
         for GBO clients. The GBO Production teams will assess the problem and
         will determine if the TechLine should be contacted.

         Computer Operations. Computer Operations is responsible for monitoring
         and reporting problems with system level hardware and software used to
         support the GBO applications. This function will be staffed on a 7X24
         hour basis and special requests outside of the Seller's normal work
         hours (7:00 a.m. to 5:00 p.m., Eastern Standard Time) will be addressed
         to the shift supervisor. All batch problems will be serviced in the
         existing traditional Job scheduling notification and escalation
         workflow.

         GBO Systems. The GBO Systems Department is responsible for all
         application sets and administration of all relevant databases. GBO
         Systems will have primary responsibility for these systems. This
         includes problem identification, resolution, maintenance and support of
         files and data. The team will also be responsible for change controls
         as it


                                      A-19


<PAGE>   34

         pertains to these applications. GBO Systems will insure that their
         information on ESP Scheduler remains current and correct.


         GBO Systems personnel will adhere to all standard Seller operations
         practices (i.e., change control, problem management, data security,
         etc.).

         Vendors. ITS will interface with vendors on behalf of GBO for system
         and layered software products as well as third party software. This
         will include but not be exclusive to hardware/software implementation
         and systems support. The use of vendor resources in resolving
         hardware/system problems will be managed by ITS. The use of vendor
         resources in resolving application problems will be managed by GBO
         Systems with ITS acting as a technical consultant.

3.       Production/System Support

         GBO Business Group Systems teams will be the primary contact for
         Computer operations on both online and batch components to the GBO
         system.

         The call list is maintained by GBO on the Mainframe Call List on TSO.
         In cases where the call individual is not available, follow
         instructions in each respective call list. The GBO clients will contact
         the GBO Systems team prior to calling the TechLine for system problems
         during normal business hours (8:00 a.m. - 5:00 p.m. Eastern Standard
         Time).

         Changes to Production Systems. Changes to the production system and
         special events such as long running monthly sweeps will be coordinated
         through a major events calendar maintained in Lotus Notes. All GBO
         batch jobs will be scheduled through ESP Scheduler.

         ITS will be notified of changes in a timely manner to allow for proper
         testing and preparation prior to implementation.

4.       Support Process

         A.       Online Processing

         Seller will use reasonable efforts to assure that the mainframe online
         component will be available Monday through Friday from 6:00 a.m.
         through 12:00 midnight Eastern Standard Time. The availability goal for
         all on-line networks will be 99.8%. Sunday availability will follow
         corporate standards with notification to GBO as to when the systems
         will be unavailable. The Sunday goal being to provide as many hours as
         possible, but the available time will not be traced for performance
         purposes.

         Seller will use reasonable efforts to assure that the midrange online
         components will be available Monday through Friday from 6:00 a.m.
         through 12:00 midnight Eastern Standard Time. The response time
         objective for the Hanstar on-line network will be 95% of all
         transactions occurring in 6 seconds or less.

         B.       Batch Processing

         All GBO batch processing will be scheduled and controlled by ESP
         Scheduler. Major batch processing includes the monthly and quarterly
         processing, monthly backups, monthly report processing and nightly
         report processing. The significant processing from these systems may be
         split over several days to avoid conflict with other processing.

         Seller will use reasonable efforts to assure that performance for the
         GBO workload will be consistent with expectations established annually
         with the GBO Capacity Planning Process.

         Network impacts caused by program abends,hardware failures or heavy
         batch processing will be communicated to GBO Systems as they occur but
         not later than 5:00 a.m., Eastern Standard Time.

         Problem Tracking and Reporting. The online system will be tracked on
         the Remedy tracking system with availability percentages reported to
         ITS Management on a monthly basis. Availability and outages will appear
         in The Daily Flash.

         Any incidence of failure will be reported to the Remedy tracking
         system. A Remedy ticket will be prepared. This information will be
         discussed at the weekly ITS Management meeting where GBO will be
         represented by the Relationship Manager named pursuant to Section 2
         above.

         Remedy tickets for any failures of the GBO Systems will be discussed at
         the 8:00 a.m. Eastern Standard Time daily ITS meeting and promptly
         assigned to the department responsible for the resolution and
         documentation of the issue.

         Remedy tickets will be discussed at the monthly ITS review meeting to
         ensure the problem has been properly tracked and resolved. Information
         text within the tickets will be kept current by GBO.

         Problem Resolution/Escalation Process. If a failure to the operating
         system or any system software occurs, either the Tech Line or the
         Operations Staff will notify the GBO and follow the existing escalation
         procedures to inform GBO and Seller management. The Relationship 
         Managers will also be notified.

5.       System Response and Recovery

         Application Notification Measures:

         Batch. The GBO batch systems will process on the mainframe processors
         in the overnight environment. Batch abends will be monitored by the
         Operations staff and calls will be made to GBO Systems within 30
         minutes of the failure.



                                      A-21


<PAGE>   36



         On-Line. The online systems will be monitored by the ITS Staff. Daytime
         failure of the hardware platform or systems software will be
         communicated to GBO Systems by ITS within 30 minutes at any time of the
         day. Nighttime failures will be communicated to GBO Systems and ITS
         Tech Support as they occur.

         Data Responsibilities. The information contained in system and data
         backups will be property of GBO and be maintained through the existing
         Seller ADSM System. The scheduling and administration of these backups
         will remain the shared responsibility of GBO Systems and Seller Tech
         Support Teams. ITS will maintain its current schedule for all
         production applications.

         Tech Support will restore mainframe data base and other system data
         from the most recent system backups. It will be the responsibility of
         the GBO system area to ensure the files are restored to the proper
         generations and are in synchronization with other department and
         company files. Tech Support will restore midrange system data from the
         most current system backups and ensure the files are in synchronization
         with necessary business needs.

         Special Considerations. The mainframe and midrange systems may be
         unavailable at specific times on Sundays due to scheduled ITS system
         maintenance and disaster recovery backups, as appropriate. The
         unavailable time will be coordinated through GBO Systems. The goal is
         to have the system available as much as possible on Sundays but it will
         not be tracked for performance purposes on that day.

         Any requests to make the system unavailable Monday through Friday will
         result in time being counted as unavailable time.

         Special arrangements for holidays will be communicated to ITS by GBO
         Systems. (The systems will be unavailable from 4:00 p.m. Christmas Eve
         (12/24) until 12:01 a.m. December 26, from 8:00 a.m. on Thanksgiving to
         8:00 a.m. on the following day and from 6:00 p.m. on December 31 until
         10:00 a.m. on January 1.)

                        OVERVIEW OF SELLER'S ITS TECHLINE

Seller's ITS TechLine provides a service to GBO on a 7X24 basis. This service
includes questions answered, level 1 problems resolution, internal and external
vendor dispatch, vendor management, problem management and problem escalation.
The TechLine is staffed with seven full-time employees and supports all
Corporate Units and Lines of Business.

GBO employees with a question or problem can call the TechLine. The TechLine
will take ownership for the call and if they can't answer the question or solve
the problem they will find someone who can.

For computer hardware problems in the Home Office and Field Offices, the
TechLine will dispatch Digital or Compucom as applicable, to repair the
equipment. (This does not include "Glass House" equipment such as CPUs, Tape
Drives and Disk Drives. Operations monitors this equipment and dispatches the
appropriate vendor when problems arise.)

For voice problems while GBO is located at Seller's corporate offices, the
TechLine will dispatch Lucent Technologies for equipment-related trouble or
maintenance. For network service, MCI or AT&T will be contacted by TechLine.

For Field Office Data Communication problems, ITS will begin problem analysis
and determine if a vendor is needed. If it is a leased line problem, ITS will
contact AT&T or MCI control centers, as appropriate, to resolve the problem. If
it is determined to be a problem with communications equipment (routers, hubs)
at the remote site, Dataserve, or other appropriate equipment vendor, will be
contacted to resolve the problem.

The TechLine will retain ownership of problems that have required a dispatch to
insure that the problem is being addressed in a timely manner. They will also
work with the vendors to resolve any service problems that may occur.

Building. If the Premises include less than the entire rentable area of any
floor, then the Premises also exclude any Common Areas, as defined below, on
such floor.

                (b) For the purposes of this Lease, Rentable Square Feet of the
Premises shall be computed as follows (and the term "Rentable Square Foot", the
term "Rentable Square Feet" or the term "RSF" shall mean the area of any such
space within the Premises as so computed):

                                  (i) The Rentable Square Feet of a single
tenancy floor shall be computed by measuring to the inside finish of the
interior walls and shall include all areas within such interior walls excluding
public stairs, elevator shafts, flues, stacks, pipe shafts, and vertical ducts
with their enclosing walls and shall include: toilets, janitor closets and

tenancy floor shall include the Premises' proportionate share of the areas
described in the preceding subsection plus the proportionate share of corridor
space necessary for the multiple tenancy of the floor. Individual offices or a
portion of a divided floor shall be computed by measuring to the inside finish
of the interior walls to the corridor side of corridors and other permanent
partitions, and to the center of partitions that separate the premises from
adjoining rentable areas.

                (c) Tenant shall have the right to use the Common Areas in
common with other tenants. The "Common Areas" include the Building's common
lobbies, corridors, stairways, and elevators necessary for access to the
Premises, the common walkways necessary for access to the Building, the loading
docks of the Building and the common toilets, corridors and elevator lobbies of
any multi-tenant floor. All use of the Common Areas shall be only upon the
reasonable and nondiscriminatory terms set forth at any time by Landlord.
Landlord may at any time make any changes, additions, replacements to the
Property including the Common Areas, that it considers desirable so long as the
same do not materially interfere with Tenant's use of the Premises. In so doing,
Landlord (i) may use or temporarily close any of the Common Areas, relocate any
portion of the Common Areas, or permanently change their configuration, and (ii)
shall use reasonable efforts to minimize interference with Tenant's normal
activities.

       2.02. Term. Both parties shall be bound by all of the terms of this Lease

nondiscriminatory rules and regulations as Landlord or its operator may
establish from time to time, and (iii) all applicable laws, ordinances, rules
and regulations; provided, however, that Tenant shall have access to such
parking seven (7) days per week, twenty-four (24) hours per day.

       Notwithstanding anything to the contrary contained herein, all parking
permits provided to Tenant shall be used solely by the partners, officers,
employees or agents or licensees of Tenant or any permitted assignees or
sublessees of Tenant occupying the Premises to the extent permitted in Section
6.04 hereof. As provided herein, Tenant shall not sublease, assign or otherwise
transfer its rights in any parking permit it receives from Landlord to any third
party including, without limitation, any other tenant in the Building.

       2.04. Termination Option. Provided that no Event of Default shall have
occurred and is continuing, Tenant shall have the option (the "Termination
Option") to terminate this Lease effective as of any monthly anniversary of the
Term Commencement Date, provided that Tenant gives written notice to Landlord of
the exercise thereof in each instance not later than thirty (30) days prior to
the respective monthly anniversary of the Term Commencement Date. In exercising
the Termination Option hereunder, Tenant acknowledges that time is of the
essence. If the Termination Option is duly exercised as aforesaid, the Term of
this Lease shall wholly cease and expire by lapse of time on the respective
monthly anniversary of the Term Commencement Date, as fully and completely as if
that day were the date herein distinctly fixed for the expiration of the Term,
and Tenant shall forthwith vacate the Premises and surrender same to Landlord on
such date in full compliance with all of the terms and conditions of this Lease.
The Termination Option is not assignable separate and apart from this Lease, is
personal to Tenant and may not be exercised or be assigned, voluntarily or
involuntarily, by or to any person or entity other than Tenant.

       2.05. Reduction of Premises. Provided no Event of Default shall have
occurred and is continuing, and provided Tenant has not previously exercised its
Termination Option pursuant to the terms and conditions of Section 2.04 above,
Tenant shall have the following options (the "Reduction Options") to reduce
certain portions of the Rentable Square Feet In The Premises and eliminate same
from the Lease, in accordance with the terms and conditions of this Section
2.05, effective as of the third monthly anniversary of the Term Commencement
Date (herein the "Third Anniversary"), the sixth monthly anniversary of the Term
Commencement Date (herein the "Sixth Anniversary") and the ninth monthly
anniversary of the Term Commencement Date (herein the "Ninth Anniversary"),
provided Tenant gives written notice to Landlord of the exercise thereof (herein
the "Reduction Notice") not later than thirty (30) days prior to the respective
Third Anniversary, Sixth Anniversary or Ninth Anniversary, as the case may be.
The Reduction Notice shall include a floor plan detailing the portion of the
Premises to be reduced from the Rentable Square Feet In The Premises and
released from the Lease (herein the 

                                       4
<PAGE>   8
"Released Premises"), provided however that (i) the Released Premises must
consist of contiguous blocks of space containing not less than 5,000 Rentable
Square Feet, and (ii) the Released Premises must be, in Landlord's reasonable
judgment, in a location which is suitable for leasing. Provided Tenant has
complied with the above terms and conditions, effective as of the respective
Third, Sixth or Ninth Anniversary, (i) the applicable Released Premises shall be
eliminated from the Rentable Square Feet In The Premises and released from the
Lease, (ii) Tenant shall vacate the applicable Released Premises and surrender
same to Landlord on such date in full compliance with all the terms and
conditions of this Lease, and (iii) the Base Rent shall be reduced accordingly
as a result of the reduction in the Rentable Square Feet In The Premises. In
exercising the respective Reduction Options hereunder, Tenant acknowledges that
time is of the essence. The Reduction Options are not assignable separate and
apart from this Lease, are personal to Tenant and may not be exercised or be
assigned, voluntarily or involuntarily, by or to any person or entity other than
Tenant.

       2.05.1 Without limiting Tenant's rights in Section 2.05 above, on or
before the Term Commencement Date, Tenant shall provide to Landlord its good
faith estimate as to the anticipated plans for Tenant's use and occupancy of the
Premises and the anticipated exercise and timing of its Reduction Options,
including a space plan detailing the location, configuration and timing of the
anticipated Released Premises.

                                   ARTICLE III

                                      RENT

       3.01. Base Rent. Beginning on the Term Commencement Date, Tenant shall
pay the Base Rent in equal monthly installments in advance on the first day of
each calendar month during the Term. For any partial month at the beginning or
end of the Term, Tenant shall pay a proportional share of the amount that would
be due for a full month, and with respect to a partial month at the beginning of
the Term, Tenant shall pay such proportional share on the Term Commencement
Date. In addition to the Base Rent, Tenant shall pay all additional rent
provided herein at the times set forth herein, or if no time for payment is
specified, then payment shall be made within thirty (30) days after Tenant's
receipt of an invoice from Landlord or another billing authority. All payments
shall be made to Landlord at Landlord's Address or such other place as Landlord
may designate in writing, without prior demand and without abatement, deduction
or offset except as may be specifically set forth herein. Tenant shall not pay,
and Landlord shall not accept, any rental payment more than one month in
advance. All charges to be paid by Tenant hereunder, other than Base Rent, shall
be considered additional rent for the purposes of this Lease, and the words
"rent" or "Rent" as used in this Lease shall mean both Base Rent and such
additional rent unless the context specifically or clearly indicates that only
the Base Rent is referenced.

                              CONDITION OF PREMISES

       4.01. As-Is Condition. Landlord shall deliver the Premises to Tenant on
the Term Commencement Date in "as-is" condition. Landlord shall have no
obligation to construct any leasehold improvements to the Premises.

       Notwithstanding the foregoing, Landlord represents and warrants that (i)
the Permitted Uses are permitted by applicable zoning laws, and (ii) to the best
of Landlord's actual knowledge, neither the Premises nor the Building are in
material noncompliance under applicable building, fire and safety laws,
including without limitation, the Americans With Disabilities Act ("ADA"). In
the event Landlord receives written notice of any such material noncompliance
under applicable building, fire and safety laws or the ADA, Landlord covenants
to make any repairs required by law in order to remedy such noncompliance, at
Landlord's sole cost and expense. Notwithstanding the foregoing, Tenant shall be
responsible, at its sole cost and expense, for ensuring that any alterations or
improvements installed or performed by Tenant are in compliance with applicable
laws.

       As used herein, the following terms used in this Section 5.01 shall have
the following meanings for purposes of this Lease:

                                  (i) The term "Business Days" means Monday
through Friday and Saturday (from 6:00 a.m. to 3:00 p.m.), excluding Legal
Holidays.

                                  (ii) The term "Business Hours" means from 6:00

the provision of Basic Services, (ii) breakdown of equipment or machinery
utilized in supplying services, or (iii) curtailment or cessation of services
due to causes or circumstances beyond the reasonable control of Landlord.
Landlord shall use reasonable diligence to make such repairs as may be required
to machinery or equipment within the Building to provide restoration of services
and, where the cessation or interruption of service has occurred due to
circumstances or conditions beyond Building boundaries, to cause the same to be
restored, by diligent application or request to the provider thereof. In no
event shall any mortgagee referred to in Section 6.09 be or become liable for
any default of Landlord under this Section 5.01(b).

                (d) Additional cleaning and janitorial services required by

                (e) Any Basic Service in amounts determined by Landlord to

                The cost chargeable to Tenant for all extra services shall
constitute additional rent.

       5.03. Window Coverings. All window coverings shall be provided by
Landlord as Building standard improvements. Tenant shall not place or maintain
any window coverings, blinds or drapes (other than those supplied by Landlord)
on any exterior window without Landlord's prior written approval which Landlord
shall have the right to grant or withhold in its absolute and sole discretion.
Tenant acknowledges that breach of this covenant will directly and adversely
affect the exterior appearance of the Building.

       5.04. Repair Obligation. Landlord's obligation with respect to repair
shall be limited to (i) the structural portions of the Building, (ii) the
exterior wall of the Building, including glass and glazing, (iii) the roof, (iv)

a timely and efficient manner; and all costs incurred by Landlord in performing

                                       8
<PAGE>   12
       5.05. Peaceful Enjoyment. So long as Tenant pays the Rent and performs
all of Tenant's covenants and agreements contained in this Lease, Tenant shall
peacefully have, hold and enjoy the Premises, subject to the other terms hereof
and other matters to which this Lease is subject and subordinate. This covenant
and the other covenants of Landlord contained in this Lease shall be binding
upon Landlord and its successors only with respect to breaches occurring during
its and their respective ownerships of Landlord's interest hereunder.

                                   ARTICLE VI

                               TENANT'S COVENANTS

       6.01. Use, Maintenance and Repairs by Tenant. Tenant shall use the
Premises solely for the Permitted Uses and for no other use or purpose, except
as permitted by Landlord pursuant to Landlord's written consent. Tenant shall be
obligated for maintenance and repair of the Premises, to keep the same in good
order, repair and condition and, upon expiration of the Term, surrender the same
to Landlord in the same condition as when leased, reasonable wear and tear,
damage by fire or other insured casualty unless such damage is caused by
Landlord or its agents, servants, employees, licensees and business invitees
(collectively "Invitees") excepted. Tenant's obligation shall include, without
limitation, the obligation to maintain and repair all walls (except the exterior
surface or structural portion of the Building or any building systems, unless
the damage thereto is caused by the negligence of Tenant or any of its Invitees,
in which event the maintenance or repair of the exterior surface or structural
portion of the Building or building systems shall be performed by Landlord and
Tenant shall pay to Landlord the costs of such maintenance or repair), floors,
ceilings, windows (except for windows located on the exterior of the Building),
doors and fixtures and to repair all damage caused by Tenant or its Invitees to
the Premises or anywhere in the Building. At the request of Tenant, Landlord
shall perform the work of maintenance and repair constituting Tenant's
obligation pursuant to this Section 6.01 at Tenant's sole cost and expense and
as an extra service to be rendered pursuant to Section 5.02(c). Any work of
repair and maintenance performed by or for the account of Tenant by persons
other than Landlord shall be performed by contractors approved by Landlord and
in accordance with procedures Landlord shall from time to time establish.
Nothing herein contained, however, shall be deemed to impose upon Tenant the
obligation for performance of work of maintenance and repair required to be
performed by reason of Landlord's negligence or wrongful acts or those of
Landlord's agents or employees.

       6.02. Taxes on Personal Property. In addition to, and wholly apart from
its obligation to pay Tenant's Share of Operating Expenses and Taxes, Tenant
shall be responsible for and shall pay, prior to delinquency, taxes or
governmental service fees, possessory interest taxes, fees or charges in lieu of
any such taxes, capital levies, or other charges imposed upon, levied with
respect to or assessed 

                                       9
<PAGE>   13
against its personal property, or the value of its Tenant Improvements or its
interests pursuant to this Lease. To the extent that any such taxes are not
separately assessed and billed to Tenant, Tenant shall pay the amount thereof as
invoiced to Tenant by Landlord.

       6.03. Waste. Tenant shall not commit or allow any waste or damage to be
committed in any portion of the Premises.

       6.04. Assignment or Sublease. Tenant shall not assign this Lease, make
any sublease of the Premises, or permit occupancy of any part thereof by anyone
other than Tenant (any such act being referred to herein as a "Transfer" and the
other party to the transaction being referred to herein as a "Transferee"), or
mortgage, pledge or otherwise transfer this Lease, without in each case
obtaining the prior written consent of Landlord, which consent may be granted or
withheld in Landlord's sole discretion. Any Transfer or attempt to Transfer
without Landlord's express written consent shall be void, and shall be a default
under this Lease. Tenant shall reimburse Landlord for legal and other expenses
incurred by Landlord in connection with any request for consent, up to $1,000.

       Notwithstanding any contrary provision herein, provided Tenant is not in
default hereunder beyond any applicable grace or notice period, Tenant may
assign this Lease to any entity controlling, controlled by or under common
control with Tenant, or any successor by merger, consolidation or sale of all or
substantially all of Tenant's assets without Landlord's prior consent, provided
the assignee is of sound financial condition, and provided further that the
Tenant originally named herein shall remain fully liable for Tenant obligations
hereunder, including, without limitation, the obligation to pay the rent and
other amounts provided under this Lease.

       6.05.  Alterations and Surrender.

       (a) Tenant shall not make or allow to be made any alterations or physical
additions in or to the Premises without obtaining the prior written consent of
Landlord, which consent shall not be unreasonably withheld with respect to
proposed alterations and additions which (i) comply with all applicable laws,
ordinances, rules and regulations, (ii) are compatible with the Building and its
mechanical, electrical, HVAC and life safety systems, and do not excessively
burden the capacity of such systems; (iii) will not interfere with the use and
occupancy of any other portion of the Building; (iv) will not affect any
structural component of the Building; and (v) satisfy the standards and comply
with the procedures and requirements required for in this Section 6.05.
Specifically, but without limiting the generality of the foregoing, Landlord's
right of consent shall encompass plans and specifications for proposed
alterations or additions, construction means and methods, the identity of any
contractor or subcontractor to be employed on the work of alterations or
additions, and the time for performance of such work. Tenant shall supply to
Landlord any information reasonably requested by Landlord in connection with its
consent hereunder. All alterations 

                                       10
<PAGE>   14
and additions permitted hereunder shall be made and performed by Tenant without
cost or expense to Landlord. Tenant shall take such steps as may be necessary to
avoid the filing, perfection or enforcement of any lien for labor or materials
against the Land or the Building by reason of work performed by or on behalf of
Tenant. Such alterations, physical additions or improvements, when made to the
Premises by Tenant shall become the property of Landlord upon the termination of
this Lease and shall be surrendered to Landlord upon the termination of this
Lease by lapse of time or otherwise; provided, however, that this clause shall
not apply to movable equipment or furniture owned by Tenant and shall not apply
to any alterations, additions or improvements specified by Tenant to Landlord
and approved by Landlord in writing prior to the installation of such additions,
alterations or improvements, and all such movable equipment or furniture,
together with any such additions, alterations or improvements so specified by
Landlord, shall be removed by Tenant, at Tenant's expense, prior to the
expiration of the Term, and Tenant shall be responsible for leaving the Premises
clean and neat. Title to all alterations, additions or improvements not removed
by Tenant pursuant to the immediately preceding sentence on or prior to the
termination of the Term shall automatically be conveyed and transferred by
Tenant to Landlord upon such expiration or termination, and shall be deemed
abandoned by Tenant and shall thereupon become the property of Landlord. Tenant
shall execute such documentation confirming and ratifying such conveyance and
transfer as Landlord shall reasonably require. Tenant shall repair at its sole
cost and expense all damage caused to the Premises or the Building by removal of
Tenant's movable equipment or furniture and such other alterations and additions
as Tenant shall be allowed or required to remove from the Premises by Landlord.

       (b) All construction work in the Premises shall be done by union
contractors and laborers, subject to the prior written approval of Landlord,
which approval shall not be unreasonably withheld or delayed, in a good and
workmanlike manner and in compliance with the Lease, all applicable laws and
lawful ordinances, regulations and orders of governmental authority and insurers
of the Building or the Premises. Before Tenant begins any work, it shall secure
all licenses and permits necessary therefor; deliver to Landlord a statement of
the names of all its contractors and subcontractors and the estimated cost of
all labor and material to be furnished by them; and cause each contractor to
carry (1) workmen's compensation insurance in statutory amounts covering all the
contractor's and subcontractor's employees, (2) comprehensive public liability
insurance with such limits as Landlord may reasonably require, but in no event
less than $3,000,000, and (3) property damage insurance with limits of not less
than $1,000,000 (all such insurance to be written in companies approved by
Landlord and insuring Landlord and Tenant as well as the contractors), and to
deliver to Landlord certificates of all such insurance; and secure casualty
insurance against loss or damage to Tenant's work pending completion and deliver
evidence of such insurance to Landlord. Tenant agrees to pay promptly when due
the entire cost of any work done in the Premises by Tenant, its agents,
employees, or independent contractors, and not to cause or permit any liens for
labor or materials performed or furnished in 

                                       11
<PAGE>   15
connection with its work to attach to the Premises and immediately to discharge
any such liens which may attach. Landlord may inspect the work at any time.
Tenant shall indemnify Landlord and hold it harmless from and against any cost,
claim, or liability arising from any work done by or at the direction of Tenant.
All work shall be done so as to minimize interference with other tenants and
with Landlord's operation of the Building or other construction work being done
by Landlord.

       6.06. Compliance with Laws and Insurance Standards. Tenant shall not
occupy, use, or permit any portion of the Premises to be occupied or used, for
any business or purpose which is disreputable or creates a fire hazard, or
permit anything to be done which would in any way increase the rate of insurance
coverage on the Building and/or its contents. If Tenant does or permits anything
to be done which shall increase the cost of any insurance policy required to be
carried hereunder, then Tenant shall reimburse Landlord, upon demand, for any
such additional premiums. Landlord shall deliver to Tenant a written statement
setting forth the amount of any such insurance cost increase and showing in
reasonable detail the manner in which it has been computed. Tenant shall comply
with all laws, ordinances, orders, rules and regulations (state, federal,
municipal or promulgated by other agencies or bodies having or claiming
jurisdiction) related to the use, condition or occupancy of the Premises or the
conduct of Tenant's business therein, including but not limited to, any
requirements concerning hiring of employees and any applicable laws and
regulations regarding accommodations for disabled persons, and Tenant shall keep
the Premises equipped with all safety appliances required by any law or
ordinance or other regulation of any public authority because of any use made by
Tenant of the Premises, and shall procure all licenses and permits so required
because of such use, and, if required by Landlord, do any work so required
because of such use, it being understood that the foregoing provisions shall not
be construed to broaden in any way the Permitted Use. Nothing done by Tenant in
its use or occupancy of the Premises shall create, require or cause imposition
of any requirement by any public authority for structural or other upgrading of
or improvement to the Building. Notwithstanding the foregoing, Tenant shall not
be liable for any capital improvements or repairs to the Premises required by
any public authority unless such requirement arises due to the particular use of
the Premises by Tenant.

       6.07. Entry for Repairs and Leasing. After reasonable notice (but not
more than two days' notice, except in emergencies when no such notice shall be
required), Landlord, its agents and representatives, shall have the right to
enter the Premises to inspect the same, to exercise such rights as may be
permitted hereunder, to make repairs or alterations to the Building or other
tenant spaces therein, to deal with emergencies, to post such notices as may be
permitted or required by law to prevent the perfection of liens against
Landlord's interest in the Building or to exhibit the Premises to prospective
tenants, purchasers, encumbrancers or others, or for any other purpose as
Landlord may deem necessary or desirable; provided, however, that Landlord shall
use reasonable efforts not to interfere with Tenant's business operations.
Tenant shall not be 

                                       12
<PAGE>   16
entitled to any abatement of Rent by reason of the exercise of any such right of
entry.

       6.08. No Nuisance. Tenant shall conduct its business and control its
agents, employees, invitees and visitors in such manner as not to create any
nuisance, or interfere with, annoy or disturb any other tenant or Landlord in
its operation of the Building.

       6.09. Subordination. Upon request of Landlord or the holder of any
Mortgage, within twenty (20) days of such request, Tenant shall execute and
deliver a recordable subordination, non-disturbance and attornment agreement or
other document in the form and containing such terms, conditions and covenants
(including without limitation those set forth below in this Section 6.09) as are
customarily used by the holder of such Mortgage, if such holder is an
institutional lender, or, if such holder is not an institutional lender,
containing such terms, conditions and covenants (including without limitation
those set forth below in this Section 6.09) as are customarily used by
institutional lenders lending funds in Boston, subordinating this Lease and the
rights of Tenant hereunder to the lien of the Mortgage and the rights of the
holder thereunder, provided that such holder of the Mortgage shall acknowledge
in writing that Tenant's quiet enjoyment under this Lease shall not be disturbed
nor shall Tenant's rights be terminated except in accordance with the terms of
this Lease. Without the consent of Tenant, the holder of any such Mortgage shall
have the right to elect to be subject and subordinate to this Lease, such
subordination to be effective upon such terms and conditions as such holder may
direct which are not inconsistent with the provisions hereof. Notwithstanding
any foreclosure or sale under any such Mortgage (or deed in lieu thereof), this
Lease shall remain in full force and effect, but Tenant shall attorn to the
holder or the purchaser at any such sale or foreclosure or the grantee of any
such deed. Upon such attornment, this Lease shall continue in full force and
effect as a direct lease between such mortgagee, purchaser or grantee, as a
successor landlord, and Tenant, upon all the terms, conditions and covenants set
forth herein, except that such mortgagee, purchaser or grantee (unless formerly
the Landlord under this Lease) shall not be (a) bound by any payment of Rent for
more than one month in advance; (b) bound by any amendment or modification of
this Lease made without the consent of the holder of the Mortgage; (c) liable in
any way to Tenant for any act or omission, neglect or default on the part of
Landlord under this Lease; (d) obligated to perform any work or improvements to
be done by Landlord in the Premises; or (e) subject to any counterclaim or
setoff which theretofore accrued to Tenant against Landlord. No owner of the
Premises shall be liable under this Lease except for breaches of Landlord's
obligations occurring while such person is the owner of the Premises.

                For purposes of this Lease, "Mortgage" shall mean any and all
mortgages securing indebtedness for money borrowed by Landlord or indebtedness
for the refinancing of any such indebtedness, provided any such mortgage grants
a lien on all or any portion of the Building, including all amendments and
modifications thereto, from time to time. Any reference to "Mortgage" and
"mortgagee" herein 

                                       13
<PAGE>   17
shall include a sale and leaseback and the grantee-lessor of a sale and
leaseback used for financing purposes.

       6.10 Estoppel Certificate. Within ten (10) days after written request by
Landlord, Tenant shall execute, acknowledge and deliver to Landlord a written
statement certifying (a) that this Lease is unmodified and in full force and
effect, or is in full force and effect as modified and stating the
modifications; (b) the amount of Base Rent and the date to which Base Rent and
additional rent have been paid in advance; (c) the amount of any security
deposited with Landlord; (d) that Landlord is not in default hereunder or, if
Landlord is claimed to be in default, stating the nature of any claimed default,
and (e) such other matters as may be reasonably requested by Landlord or any
prospective purchaser or mortgagee of the Property. Any such statement may be
relied upon by a purchaser, assignee or lender. Tenant's failure to execute and
deliver such statement within the time required shall be a default under this
Lease and shall also be conclusive evidence that (1) this Lease is in full force
and effect and has not been modified except as represented by Landlord; (2)
there are no uncured defaults in Landlord's performance and Tenant has no right
of offset, counterclaim or deduction against rent; and (3) not more than one
month's Base Rent has been paid in advance.

       6.11. Tenant's Remedies. Tenant shall look solely to Landlord's interest
in the Building for recovery of any judgment from Landlord. Landlord, its
agents, employees, and, if Landlord is a partnership, its partners, whether
general or limited, or if Landlord is a corporation, its directors, officers or
shareholders, shall never be personally liable for any such judgment. Any lien
obtained to enforce any such judgment and levy of execution thereon shall be
subject and subordinate to any Mortgage.

       6.12. Rules and Regulations. Tenant shall comply with the rules and
regulations for the Building attached as Exhibit E and such amendments thereto
as Landlord may adopt from time to time with prior notice to Tenant.

       6.13. Personal Property at Tenant's Risk. All of the furnishings,
fixtures, equipment, effects and property of every kind, nature, and description
of Tenant and of all persons claiming by, through and under Tenant which, during
the continuance of this Lease or any occupancy of the Premises by Tenant or
anyone claiming under Tenant, may be on the Premises or elsewhere in the
Building, shall be at the sole risk and hazard of Tenant, and if the whole or
any part thereof shall be destroyed or damaged by fire, water or otherwise, by
the leakage or bursting of water pipes, steam pipes, or other pipes, or by theft
or from any other cause, no part of said loss or damage is to be charged to or
be borne by Landlord, except to the extent caused by Landlord's negligence or
willful misconduct and except Landlord shall in no event be held harmless or
exonerated for any liability to Tenant or to any other person, for any injury,
loss, damage or liability to the extent such indemnity, hold harmless or
exoneration is prohibited by law.

<PAGE>   18
       6.14. Payment of Landlord's Expenses. Tenant shall pay, as additional
rent, all reasonable costs, counsel and other fees incurred by Landlord in
connection with all requests by Tenant for consent or approval hereunder, and
the successful enforcement by Landlord of any obligation of Tenant under this
Lease.

       6.15. Environmental Compliance. Tenant shall not cause or permit any
hazardous or toxic wastes, hazardous or toxic substances or hazardous or toxic
materials except for ordinary office and cleaning supplies (collectively,
"Hazardous Materials") to be used, generated, stored or disposed of on, under or
about, or transported to or from, the Premises (collectively, "Hazardous
Materials Activities") without first receiving Landlord's written consent, which
may be withheld for any reason and revoked at any time. If Landlord consents to
any such Hazardous Materials Activities, Tenant shall conduct them in strict
compliance (at Tenant's expense) with all applicable Regulations, as hereinafter
defined, and using all necessary and appropriate precautions to prevent any
spill, discharge, release or exposure to persons or property. Landlord shall not
be liable to Tenant for any loss, cost, expense, claims, damage or liability
arising out of any Hazardous Materials Activities by Tenant, Tenant's employees,
agents, contractors, licensees, customers or invitees, whether or not consented
to by Landlord. Tenant shall indemnify, defend with counsel acceptable to
Landlord, and hold Landlord harmless from and against any and all loss, costs,
expenses, claims, damages or liabilities arising out of all Hazardous Materials
Activities on the Premises by Tenant, its agents and employees during the Term,
whether or not consented to by Landlord. For purposes hereof, Hazardous
Materials shall include but not be limited to substances defined as "hazardous
substances", "toxic substances", or "hazardous wastes" in the Federal
Comprehensive Environmental Response, Compensation and Liability Act of 1980, as
amended; the Federal Hazardous Materials Transportation Act, as amended; and the
Federal Resource Conservation and Recovery Act, as amended ("RCRA"); those
substances defined as "hazardous wastes" in the Massachusetts Hazardous Waste
Facility Siting Act, as amended (Massachusetts General Laws Chapter 21D); those
substances defined as "hazardous materials" or "oil" in Massachusetts General
Laws Chapter 21E, as amended; and as such substances are defined in any
regulations adopted and publication promulgated pursuant to any of said laws
(collectively, "Regulations"). If Landlord consents to any Hazardous Materials
Activities, prior to using, storing or maintaining any Hazardous Materials on or
about the Premises, Tenant shall provide Landlord with a list of the types and
quantities thereof, and shall update such list as necessary for continued
accuracy. Tenant shall also provide Landlord with a copy of any Hazardous
Materials inventory statement required by any applicable Regulations, and any
update filed in accordance with any applicable Regulations. If Tenant's
activities violate or create a risk of violation of any Regulations or cause a
spill, discharge, release or exposure to any persons or property, Tenant shall
cease such activities immediately upon notice from Landlord. Tenant shall
immediately notify Landlord both by telephone and in writing of any spill,
discharge, release or exposure of Hazardous Materials or of any condition
constituting an "imminent hazard" under any 

                                       15
<PAGE>   19
Regulations. Landlord, Landlord's representatives and employees may enter the
Premises at any time during the Term to inspect Tenant's compliance herewith,
and may disclose any spill, discharge, release, or exposure or any violation of
any Regulations to any governmental agency with jurisdiction. Nothing herein
contained shall prohibit Tenant from using minimal quantities of cleaning fluid
and office supplies which may constitute Hazardous Materials but which are
customarily present in premises devoted to office use, provided that such use is
in compliance with all Regulations and shall be subject to all of the other
provisions of this Section 6.15.

                                   ARTICLE VII

                            CASUALTY, EMINENT DOMAIN

       7.01. Casualty Insurance. Landlord shall maintain, or cause to be
maintained, a policy or policies of insurance with the premiums thereon fully
paid in advance, issued by and binding upon an insurance company of good
financial standing, insuring the Building against loss or damage by fire or
other insurable hazards and contingencies for at least eighty percent (80%) of
the replacement cost thereof (or such minimum amount as shall be required to
eliminate operation of coinsurance provisions); provided, that Landlord shall
not be obligated to insure any furniture, equipment, machinery, goods or
supplies not covered by this Lease which Tenant may keep or maintain in the
Premises, or any alteration, addition or improvement which Tenant may make upon
the Premises. If the annual premiums charged Landlord for such casualty
insurance exceed the standard premium rates because the nature of Tenant's
operations results in extra-hazardous exposure, then Tenant shall, upon receipt
of appropriate premium invoices, reimburse Landlord for such increases in
premium as additional rent.

       7.02. Liability Insurance. Landlord (with respect to the Building) and
Tenant (with respect to the Premises) shall maintain or cause to be maintained a
policy or policies of comprehensive general liability insurance with the
premiums thereon fully paid in advance issued by and binding upon an insurance
company of good financial standing, such insurance to afford minimum protection
of not less than Three Million Dollars ($3,000,000.00) for personal injury or
death in any one occurrence and of not less than One Million Dollars
($1,000,000.00) for property damage in any one occurrence. The coverages
required to be carried shall be extended to include blanket contractual
liability, personal injury liability (libel, slander, false arrest and wrongful
eviction), and broad form property damage liability. The certificate shall
indicate that the insurance provided specifically recognizes the liability
assumed by Tenant under this Lease and that the Tenant's insurance is primary
with any other insurance available to Landlord or any other named insured being
excess. Upon request of either party, the other party shall provide reasonable
evidence that the insurance required to be maintained hereunder is in full force
and effect.

       7.03.  Tenant's Insurance.

                                       16
<PAGE>   20
                (a) Tenant shall carry fire and special extended coverage
insurance on Tenant's own fixtures and personal property in the Premises in the
amount of their full replacement cost. In addition, Tenant shall maintain
workers' compensation insurance and all such other insurance as may be required
by applicable law. All policies required to be carried by Tenant hereunder and
all evidence of insurance provided to Landlord shall be issued by responsible,
financially sound companies qualified to do business and in good standing in the
Commonwealth of Massachusetts and shall contain an endorsement showing that
Landlord and each holder of a Mortgage (disclosed in writing to Tenant) is
included as an additional insured (except as to workers' compensation
insurance), as its interests may appear and an endorsement whereby the insurer
agrees not to cancel or alter the policy without not less than thirty (30) days
prior written notice to Landlord, to such mortgagee and all other named
insureds. Tenant shall, on or prior to the Term Commencement Date, deposit with
Landlord certificates of such insurance, and thereafter, on or prior to fifteen
(15) days before the expiration date of any coverage thereunder, shall deposit
with Landlord certificates evidencing the renewal of such policies. Any such
insurance may be maintained by Tenant under a blanket policy or policies,
however, that the minimum amount of the total insurance afforded by such blanket
policy which shall be allocable to the Premises and any sublimits of such policy
allocable to the Premises, shall be in amounts which shall not be less than the
amounts of the insurance required hereunder, and the protection afforded to
Landlord and each holder of a Mortgage under such policy shall be not less than
that which would have been afforded under a separate policy or policies relating
only to the Premises, and the certificate evidencing such insurance shall
contain provisions confirming the foregoing.

                (b) In the event that Tenant fails to provide evidence of
insurance required to be provided by Tenant hereunder, Landlord shall be
authorized (but not required) to procure such coverage in the amounts stated
with all costs thereof to be chargeable to Tenant as additional rent, and
payable by Tenant upon receipt of written invoice therefor.

       7.04. Indemnity and Exoneration. Except to the extent such indemnity or
exoneration is prohibited by law,

                (a) As a material consideration to Landlord for executing this
Lease, Tenant assumes all risk of damage or injury to any person or property in,
on, or about the Premises from any cause, including without limitation, injury
or damage which may be sustained by the person or property of Tenant, its
employees, invitees, or any other person in or about the Premises, caused by or
resulting from (i) theft, burglary or acts of unauthorized persons in or about
the Building, (ii) any act of force majeure or any repair or alteration of any
part of the Building or failure to make any such repair or (iii) fire, steam,
electricity, gas, water or rain which may leak or blow from or into any part of
the Premises, or from the breakage, leakage, obstruction, or other defects of
pipes, sprinklers, wires, appliances, plumbing, air-conditioning or lighting
fixtures, whether 

                                       17
<PAGE>   21
such damage or injury results from conditions arising upon the Premises, any
other portion of the Property, or other sources, except the negligence or
willful misconduct of, or breach of this Lease, by Landlord, its agents,
employees, contractors or licensees provided, however, that nothing herein
contained shall limit Tenant's rights against any third party other than
Landlord, its agents, contractors or employees. Landlord shall not be liable to
Tenant or any other person or entity for any damages arising from any act or
omission of any other tenant of the Building.

                (b) Tenant shall indemnify Landlord and hold Landlord harmless
of and from any and all loss, cost, damage, injury or expense arising out of or
related to claims of injury to or death of persons, damage to property occurring
or resulting directly or indirectly from the negligence or willful misconduct of
Tenant, its agents, employees and contractors in or about the Premises or the
Building, excluding however any such claim arising as a result of the gross
negligence or willful misconduct or breach of this Lease on the part of
Landlord, its agents, contractors or employees, such indemnity to include,
without limitation, the obligation to provide all costs of defense against any
such claims; and

                (c) Tenant shall hold and save Landlord harmless and indemnify
Landlord of and from any and all loss, cost, damage, injury or expense arising
out of or in any way related to claims for work or labor performed, materials or
supplies furnished to or at the request of Tenant or in connection with
performance of any work done for the account of Tenant in the Premises or the
Building, such indemnity to include, without limitation, the obligation to
provide all costs of defense against any such claim.

                (d) Landlord shall indemnify, protect, defend and hold harmless
the Tenant, its directors, officers, agents, lenders, employees, successors and
assigns from and against any and all claims, expenses or liabilities of whatever
nature arising from any negligence, willful misconduct or breach of this Lease
by Landlord, its officers, agents, employees, contractors or licensees.

       7.05. Waiver of Subrogation Rights. Anything in this Lease to the
contrary notwithstanding, Landlord and Tenant each waive all rights or recovery,
claim, action or cause of action against the other, its agents (including
partners, both general and limited), officers, directors, shareholders or
employees, for any loss or damage that may occur to the Premises, or any such
party thereto, to the Building or to any personal property of such party
therein, by reason of fire, the elements, or any other cause which are required
to be insured against under the terms of the fire and extended coverage
insurance policies obtained pursuant to this Lease, regardless of cause or
origin, including negligence of the other party hereto, its agents, officers or
employees; and each party covenants that no insurer shall hold any right of
subrogation against such other party. Landlord and Tenant shall advise insurers
of the foregoing and such waiver shall be a part of each policy maintained by
such party which applies to the Premises, any part of the Building or Tenant's
use and occupancy of any part thereof; provided that this 

                                       18
<PAGE>   22
waiver shall be null and void if the affected insurer refuses to consent to such
waiver, and provided further that all costs associated with obtaining insurer
consent shall be borne by the party benefited by such waiver.

       7.06.  Condemnation and Loss or Damage.

                (a) If the Premises or any portion of the Building shall be
taken or condemned for any public purpose to such an extent as to render the
Premises unsuitable for Tenant's use as reasonably determined by Landlord, this
Lease shall, at the option of either party (provided such option shall be
exercised by the giving of notice by the exercising party to the other party
within sixty (60) days from the date the exercising party has been notified in
writing of such taking or condemnation) forthwith cease and terminate as of the
date of the taking. All proceeds from any taking or condemnation of the Premises
shall belong to and be paid to Landlord and Tenant hereby assigns to Landlord
its interest in said proceeds subject to the rights of any holder of any
Mortgage; provided, however, that Landlord shall cooperate with Tenant if Tenant
seeks, in a separate proceeding, to recover, at its cost and expense,
compensation for its moving expenses and personal property diminishing or
delaying the award payable to Landlord on account of any taking or condemnation.

                (b) In the event of a temporary taking (i.e. less than ninety
(90) days) of a portion of the Premises, there shall be no abatement of Rent and
Tenant shall remain fully obligated for performance of all of the covenants and
obligations on its part to be performed pursuant to the terms of this Lease. All
proceeds awarded or paid with respect thereto shall belong to Landlord.

       7.07. Damage Due to Fire and Casualty. In the event of a fire or other
casualty in the Premises, Tenant shall immediately give notice thereof to
Landlord. The following provisions shall then apply:

                (a) If the damage is limited solely to the Premises and the
Premises can be restored to substantially the condition that existed immediately
prior to the damage within six (6) months from the date of damage or
destruction, then, subject to any limitation contained in any Mortgage, Landlord
shall be obligated to rebuild the same and shall proceed diligently to do so;
provided, however, that Landlord shall have no obligation to repair or restore
the Premises or leasehold improvements except to the extent that Landlord
realizes insurance proceeds, if any, sufficient for such purposes and for all
other restoration and repair purposes and to the extent such proceeds are not
applied on account of the indebtedness secured by any Mortgage.

                (b) If portions of the Building outside the boundaries of the
Premises are damaged or destroyed (whether or not the Premises are also damaged
or destroyed) and the Premises and the Building can both be made tenantable with
substantially all damage repaired within six (6) months from the date of damage
or destruction, and provided that Landlord determines that such repair and
restoration is 

                                       19
<PAGE>   23
economically feasible, then subject to any limitation contained in any Mortgage,
Landlord shall be obligated to do so; provided, however, that Landlord shall
have no obligation to repair or restore the Premises or leasehold improvements
except to the extent that Landlord realizes insurance proceeds, if any,
allocable thereto and sufficient for such purpose and for all other restoration
and repair purposes.

                (c) If neither subsection 7.07(a) nor 7.07(b) above applies,
Landlord shall notify Tenant within sixty (60) days after such date and either
Tenant or Landlord may terminate this Lease within thirty (30) days after the
date of such notice; provided, however, that Landlord or its mortgagee shall
have the right to elect to reconstruct the Building and the Premises (provided
that the mortgagee shall undertake to reconstruct within the same time periods
allowed to Landlord), in which event Landlord or its mortgagee shall so notify
Tenant within said sixty (60) day period and Tenant shall thereupon have no
right to terminate this Lease except as otherwise set forth in the Lease.

                (d) During any period when Tenant's use of the Premises is
significantly affected by damage or destruction, Rent shall abate
proportionately until such time as the Premises are restored as reasonably
determined by Landlord and no portion of the Rent so abated shall be subject to
subsequent recapture.

                (e) The proceeds from any insurance paid by reason of damage to
or destruction of the Building or any part thereof or any other element,
component or property insured by Landlord shall belong to and be paid to
Landlord, subject to the rights of the holder of any Mortgage, and Tenant hereby
assigns to Landlord any interest in said proceeds.

                                  ARTICLE VIII

                                     DEFAULT

       8.01. Events of Default. The occurrence of any of the following shall
constitute an "Event of Default" on the part of Tenant:

                (a) Nonpayment Of Rent. Failure to pay any payment of Rent due
and payable hereunder, upon the date when payment is due, such failure
continuing for a period of ten (10) business days after written notice of such
failure; provided, however, that Landlord shall not be required to provide such
notice more than twice during any twelve (12) month period with respect to
non-payment of Base Rent, the third such non-payment constituting default
without requirement of notice;

                (b) Other Obligations. Failure to perform any obligation,
agreement or covenant under this Lease other than those matters specified in
Section 8.01(a), such failure continuing for twenty (20) business days after
written notice of such failure (or such longer period as is reasonably necessary
to remedy such default, provided 

                                       20
<PAGE>   24
that Tenant shall within such twenty (20) business-day period have commenced
such remedy and thereafter Tenant shall continuously and diligently pursue such
remedy at all times until such default is cured);

                (c) Abandonment. Abandonment of the Premises or any part thereof
during the Term. Tenant shall be deemed to have abandoned the Premises if the
Premises remain substantially vacant or unoccupied for a period of thirty (30)
days;

                (d) General Assignment. A general assignment by Tenant for the
benefit of creditors;

                (e) Bankruptcy. The filing of any voluntary petition in
bankruptcy by Tenant, or the filing of an involuntary petition by Tenant's
creditors, which involuntary petition remains undischarged or unstayed for a
period of sixty (60) days. In the event that under applicable law the trustee in
bankruptcy or Tenant has the right to affirm this Lease and continue to perform
the obligations of Tenant hereunder, such trustee or Tenant shall, in such time
period as may be permitted by the bankruptcy court having jurisdiction, cure all
defaults of Tenant hereunder outstanding as of the date of the affirmance of
this Lease and provide to Landlord such adequate assurances as may be necessary
to ensure Landlord of the continued performance of Tenant's obligations under
this Lease;

                (f) Receivership. The employment of a receiver to take
possession of substantially all of Tenant's assets or the Premises, if such
receivership remains undissolved for a period of ten (10) business days after
creation thereof;

                (g) Attachment. The attachment, execution or other judicial
seizure of all or substantially all of Tenant's assets or the Premises, if such
attachment or other seizure remains undismissed or undischarged for a period of
ten (10) business days after the levy thereof;

                (h) Insolvency. The admission by Tenant in writing of its
inability to pay its debts as they become due, the filing by Tenant of a
petition seeking any reorganization, arrangement, composition, readjustment,
liquidation, dissolution or similar relief under any present or future statute,
law or regulation, the filing by Tenant of an answer admitting or failing timely
to contest a material allegation of a petition filed against Tenant in any such
proceeding or, if within sixty (60) days after the commencement of any
proceeding against Tenant seeking any reorganization, or arrangement,
composition, readjustment, liquidation, dissolution or similar relief under any
present or future statute, law or regulation, such proceeding shall not have
been dismissed.

       8.02.  Remedies Upon Default.

                (a) If an Event of Default occurs, Landlord shall have the
right, with or without notice or demand, immediately to terminate this Lease,
and at any time thereafter recover possession of the 

                                       21
<PAGE>   25
Premises or any part thereof and expel and remove therefrom Tenant and any other
person occupying the same, by any lawful means, and again repossess and enjoy
the Premises without prejudice to any of the remedies that Landlord may have
under this Lease, or at law or equity by reason of Tenant's default or of such
termination.

                (b) Even though Tenant has breached this Lease, this Lease shall
continue in effect for so long as Landlord does not terminate Tenant's right to
possession under Section 8.02(a) hereof, and Landlord may enforce all of its
rights and remedies under this Lease, including, without limitation, the right
to recover Rent as it becomes due. Acts of maintenance, preservation or efforts
to lease the Premises or the appointment of a receiver upon application of
Landlord to protect Landlord's interest under this Lease shall not constitute an
election to terminate Tenant's right to possession.

       8.03. Damages Upon Termination. Should Landlord terminate this Lease
pursuant to the provisions of Section 8.02(a) hereof, Landlord shall have all
the rights and remedies of a landlord in law or in equity. Upon such
termination, in addition to any other rights and remedies to which Landlord may
be entitled under applicable law, Landlord shall be entitled to recover from
Tenant: (1) the worth at the time of award of the unpaid Rent and other amounts
which had been earned at the time of termination; (ii) the worth at the time of
award of the amount by which the unpaid Rent which would have been earned after
termination until the time of award exceeds the amount of such Rent loss that
the Tenant proves could have been reasonably avoided; (iii) the worth at the
time of award of the amount by which the unpaid Rent for the balance of the Term
after the time of award exceeds the rental value of the Premises for the balance
of the Term; and (iv) any other amount necessary to compensate Landlord for all
the detriment proximately caused by Tenant's failure to perform its obligations
under this Lease or which, in the ordinary course, would be likely to result
therefrom. Tenant further covenants, as an additional cumulative obligation
after any such termination, to punctually pay to Landlord all sums and perform
all obligations which Tenant covenants in this Lease to pay and to perform, as
if this Lease had not been terminated. In calculating the amounts to be paid by
Tenant pursuant to this Section 8.03, Tenant shall be credited with any amount
paid to Landlord pursuant to this Section 8.03 and also (in respect of the
amounts referred to in (i) and (ii)) the net proceeds of rent obtained by
Landlord by reletting the Premises through the time of award, after deducting
all Landlord's expenses in connection with such reletting, including, without
limitation, all repossession costs, brokerage commissions, fees for legal
services and expenses of preparing the Premises for reletting, it being agreed
by Tenant that Landlord may (x) relet the Premises or any part thereof for a
term or terms which may at Landlord's option be equal or less than or exceed the
period which would otherwise have constituted the balance of the Term and may
grant such concessions and free rent as Landlord in its sole judgment considers
advisable or necessary to relet the same and (y) make such alterations, repairs
and decorations in the Premises as Landlord in its sole judgment considers
advisable or necessary to relet the same, and no action of Landlord in
accordance with the foregoing or failure to relet or 

                                       22
<PAGE>   26
collect rent under Landlord's reletting of the Premises shall operate or be
construed to release or reduce Tenant's liability as aforesaid. The "time of
award" shall refer to such time as (I) Tenant shall, as a settlement of the
amounts due pursuant to this Section 8.03, pay to Landlord such sums pursuant to
a written agreement in form and substance satisfactory to Landlord, or (II) the
date on which a judgment shall be entered in a court of competent jurisdiction
to the effect that Tenant shall pay Landlord the amounts due and owing pursuant
to this Section 8.03. The "worth at the time of award" of the amounts referred
to in (i) and (ii) shall mean such amounts together with interest at the lesser
of eighteen percent (18%) per annum or the maximum rate allowed by law. The
"worth at the time of award" of the amount referred to in (iii) shall mean such
amounts as computed by referenced to competent appraisal evidence or the formula
prescribed by and using the lowest discount rate permitted under applicable law.

       8.04. Computation of Rent for Purposes of Default. For purposes of
computing unpaid Rent which would have accrued and become payable under this
Lease pursuant to the provisions of Section 8.03, unpaid Rent shall consist the
total Base Rent for the balance of the Term.

       8.05.  Intentionally Deleted.

       8.06. Rights of Landlord in Bankruptcy. Nothing contained in this Lease
shall limit or prejudice the right of Landlord to prove for and obtain in
proceedings for bankruptcy or insolvency, by reason of the termination of this
Lease, an amount equal to the maximum allowed by any statute or rule of law in
effect at the time when, and governing the proceedings in which, the damages are
to be proved, whether or not the amount be greater, equal to, or less than the
amount of the loss or damages referred to in this Article VIII.

       8.07. Late Charge. In addition to its other remedies, Landlord shall have
the right to add to the amount of any payment required to be made by Tenant
hereunder, and which is not paid on or before the date the same is due, an
amount equal to ten percent (10%) per annum of the delinquency thereof that the
delinquency remains outstanding, the parties agreeing that Landlord's damage by
virtue of such delinquencies would be difficult to compute and the amount stated
herein represents a reasonable estimate thereof. The late charge shall be due
upon demand by Landlord. Tenant shall reimburse Landlord for all costs and
expenses (including reasonable attorney's fees) incurred by Landlord to recover
the late charges due hereunder.

                                   ARTICLE IX

                                  MISCELLANEOUS

       9.01. No Waiver. Failure of Landlord or Tenant to declare any default
immediately upon occurrence thereof, or delay in taking any action in connection
therewith, shall not waive such default, but Landlord or Tenant, as the case may
be, shall have the right to declare any such default at any time thereafter.

                                       23

       9.02. Holding Over. In the event of holding over by Tenant after
expiration or termination of this Lease without the written consent of Landlord,
Tenant shall pay for each month of holdover tenancy one hundred and fifty
percent (150%) of the Rent which Tenant was obligated to pay for the month
immediately preceding the end of the Term for each month or partial month of any
such hold-over period together with such other amounts as may become due
hereunder. No holding over by Tenant after the Term shall operate to extend the
Term. In the event of any unauthorized holding over, Tenant shall indemnify
Landlord (i) against all claims for damages by any other tenant to whom Landlord
may have leased all or any part of the Premises covered hereby effective upon
the termination of this Lease, and (ii) for all other losses, costs and

changed or amended, except by an instrument in writing signed by both parties
hereto.

       9.04. Transfers by Landlord. Landlord shall have the right to transfer

obligations shall thereafter accrue against the transferring or assigning person
as Landlord hereunder.

       9.05. Severability. If any term or provision of this Lease, or the
application thereof to any person or circumstances, shall to any extent be
invalid or unenforceable, the remainder of this Lease, or the application of
such provision to persons or circumstances other than those as to which it is
invalid or unenforceable, shall not be affected thereby, and each provision of
this Lease shall be valid and shall be enforceable to the fullest extent
permitted by law.

       9.06. Notices. All notices, demands, consents and approvals which may be
or are required to be given by either party to the other hereunder shall be in
writing and shall be deemed to have been delivered on the earlier of (i) the

depository, postage pre-paid, sent registered or certified mail, return receipt
requested, and addressed to the party to be notified at the address for such
party specified in Section 1.02 hereof, or to such other place as the party to
be notified may from time to time designate by at least fifteen (15) days notice

to the benefit of Landlord, its successors and assigns; and

<PAGE>   28
shall be binding upon and inure to the benefit of Tenant, its successors, and to
the extent assignment may be permitted as of right or approved by Landlord
hereunder, Tenant's assigns.

       9.09. Applicable Law. All rights and remedies of Landlord and Tenant
under this Lease shall be construed and enforced according to the laws of the
Commonwealth of Massachusetts.

       9.10. Time of the Essence. Time is of the essence of each and every
covenant herein contained.

       9.11. Submission Not an Option. The submission of this Lease for
examination does not constitute a reservation of or option for the Premises or
an offer to lease, it being understood and agreed that neither Landlord nor
Tenant shall be legally bound with respect to the leasing of the Premises unless
and until this Lease has been executed and delivered by both Landlord and
Tenant.

       9.12. Brokerage. Tenant and Landlord each warrant to the other that it
has had no dealings with any broker or agent in connection with this Lease other
than the Broker, and each covenants to defend (with counsel reasonably approved
by the other party), hold harmless and indemnify the other party from and
against any and all costs, expense or liability for any compensation, commission
and charges claimed by any broker or agent except the Broker, arising out of the
warranting party's dealings in connection with this Lease or the negotiation
thereof.

       9.13. Waiver of Jury Trial. Landlord and Tenant hereby waive trial by
jury in any action, proceeding or counterclaim brought by either of the parties
hereto against the other, on or in respect of a matter whatsoever arising out of
or in any way connected with this Lease, the relationship of Landlord and Tenant
hereunder, Tenant's use or occupancy of the Premises, and/or any claim of injury
or damages.

       9.14. All Agreements Contained. This Lease contains all of the agreements
of the parties with respect to the subject matter hereof and supersedes all
prior dealings between them with respect to such subject matter.

       9.15. Cumulative Remedies. The specific remedies to which Landlord may
resort under the terms of this Lease are cumulative and are not intended to be
exclusive of any other remedies or means of redress to which it may be lawfully
entitled in case of any breach or threatened breach by Tenant of any provisions
of this Lease. In addition to the other remedies provided in this Lease,
Landlord may be entitled to the restraint by injunction of the violation or
attempted or threatened violation of any of the covenants, conditions or
provisions of this Lease or to a decree compelling specific performance of any
such covenants, conditions or provisions.

       9.16. Failure to Enforce. The failure of Landlord to seek redress for
violation of, or to insist upon strict performance of, any covenant or condition
of this Lease, or with respect to such 

                                       25
<PAGE>   29
failure of Landlord to enforce any of the rules and regulations referred to
herein, whether heretofore or hereafter adopted by Landlord, shall not be deemed
a waiver of such violation nor prevent a subsequent act which would have
originally constituted a violation from having all the force and effect of the
original violation, nor shall the failure of Landlord to enforce any of said
rules and regulations against any other tenant in the Building be deemed a
waiver of any such rules or regulations. The receipt by Landlord of Rent with
knowledge of the breach of any covenant of this Lease shall not be deemed a
waiver of such breach. No provision of this Lease shall be deemed to have been
waived by Landlord, unless such waiver shall be in writing and signed by
Landlord. No consent or waiver, express or implied, by Landlord to any breach of
any agreement or duty shall be construed as a waiver or consent to or of any
other breach of the same or any other agreement or duty.

       9.17. Representations by Tenant. Tenant represents and warrants that any
financial statements provided by it to Landlord were true, correct and complete
when provided, and that no material adverse change has occurred since that date
that would render them inaccurate or misleading. Tenant represents and warrants
that those persons executing this Lease on Tenant's behalf are duly authorized
to execute and deliver this Lease on its behalf, and that this Lease is binding
upon Tenant in accordance with its terms. Simultaneously with the execution of
this Lease, Tenant shall deliver evidence of such authority to Landlord in form
satisfactory to Landlord.

       9.18. Force Majeure. When a period of time is herein prescribed for
action to be taken by Landlord, Landlord shall not be liable or responsible for,
and there is excluded from the computation for any such period of time, any
delays due to strikes, riots, acts of God, shortages of labor or materials, war,
governmental laws, regulations or restrictions or any other cause of any kind
whatsoever which are beyond the control of Landlord. Subject to the preceding
sentence, time is of the essence of every part of this Lease.

       9.19. Limitation on Liability. Landlord's rights hereunder are solely for
Landlord's benefit, and Landlord has no duty to exercise them for the benefit of
Tenant or others. Any liability of Landlord to Tenant under this Lease, or
arising from the relationship under it, is limited to the interest of Landlord
in the Building, and Landlord shall not be personally liable for any deficiency;
but this does not limit or deny any remedies which do not involve personal
liability.

       9.20. Notice of Lease. Tenant agrees not to record this Lease, but on the
request of either party hereto, both parties hereto shall execute and deliver
(i) a notice of this Lease in form appropriate for recording or registration,
(ii) an agreement setting forth the Term Commencement Date, (iii) a notice in
form appropriate for recording or registration of any amendment of this Lease,
(iv) an agreement by Tenant to make payments and give notices to whatever
individual or entity shall be designated by Landlord for receiving any such
notice or payment and to comply with the provisions of any assignment of rents
granted to the holder of any Mortgage, and (v) if 

                                       26
<PAGE>   30
this Lease is terminated before the expiration of the Term, an instrument in
form appropriate for recording or registration pursuant to which Tenant
acknowledges the date of termination. If Tenant unreasonably refuses to execute
any of the notices, amendments, agreements and instruments provided for in the
immediately preceding sentence, or in Sections 6.05 and 6.10, within ten (10)
business days after Landlord gives notice to Tenant requesting execution of the
same, Landlord may effect such execution on behalf of Tenant as Tenant's
attorney-in-fact and Tenant hereby grants to Landlord an irrevocable power of
attorney to execute on behalf of Tenant each such notice, amendment, agreement
and instrument, which power is coupled with an interest.

        IN WITNESS WHEREOF, the parties hereto have executed this Lease as a
sealed instrument as of the day and year first above written.

                                     ANNEX L

                      AGREED GAAP PRINCIPLES AND PROCEDURES

The Closing GAAP Balance Sheet shall be prepared on basis in conformity with
accounting principles that are generally accepted for stock life insurance
companies as further specified below and in accordance with the following:

        (1)       the polices and practices provided for in Note 1 - Summary of
                  Significant Accounting Policies and Note 5 - Related Party
                  Transactions to the Financial Statements, as follows:

NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

The accompanying combined financial statements include certain operations of the
group life and accident and health insurance business of John Hancock Mutual
Life Insurance Company (John Hancock) and Cost Care, Inc., Hancock Association
Services Group and Tri-State, Inc. (the Group Benefits Operations or GBO). Cost
Care, Inc., Hancock Association Services Group and Tri-State, Inc. are wholly
owned, indirect subsidiaries of John Hancock, as defined in this agreement..

The GBO business is expected to be acquired pursuant to an agreement being
negotiated between John Hancock and WellPoint Health Networks, Inc. (see Note
7). GBO has transactions with affiliated companies, the terms and conditions of
which are determined by GBO and the members of the affiliated group. GBO
operating costs and expenses consist of direct costs, allocated costs, and
allocated corporate overhead. Accordingly, these financial statements might not
be indicative of the financial position and results of operations that would
have occurred had GBO operated as a nonaffiliated entity.

The combined financial statements of GBO have been prepared in conformity with
generally accepted accounting principles (GAAP), applied on a consistent basis,
for stock life insurance companies (stock life basis), which vary from statutory
accounting practices as prescribed or permitted by the Commonwealth of
Massachusetts Division of Insurance and the National Association of Insurance
Commissioners.

All significant intercompany accounts and transactions have been eliminated.

The preparation of financial statements in conformity with GAAP requires
management to make estimates and assumptions that affect amounts reported in the

could change in the future as more information becomes known, which could impact
the amounts reported and disclosed herein.

OPERATIONS

GBO is not a legal entity but conducts group life and accident and health
insurance business through John Hancock and its subsidiaries. GBO principally
offers group life and accident and health insurance products and administrative
services to its group customers in all fifty states, the District of Columbia
and Puerto Rico.

For fully insured contracts, the policyholder elects either prospectively pooled
experience rated insurance or experience rated refund eligible insurance.
Further, the policyholder is offered fully funded or partially funded payment
options. The partially funded Minimum Premium Contract incorporates similar
insurance risks to GBO but with employer self-funding of claims, introducing
credit risk relating to employer funding. Administrative services contracts are
provided to self-insured plans whereby GBO provides the claims management and
processing service, and in many cases excess or stop-loss insurance. GBO also
provides a range of health care cost management services including pre-admission
review for in-patient hospital admission and preferred provider management to
insurance underwriters and private businesses for a predetermined, periodic fee
and on a fee-for-service basis.

GBO has dedicated sales, underwriting, actuarial, product development, premium
and claims operations, and systems support. Products are distributed through
group representatives, who are John Hancock employees, or through
intermediaries.

PENDING ACCOUNTING STANDARDS

In April 1993, the Financial Accounting Standards Board (FASB) issued
Interpretation No. 40, "Applicability of Generally Accepted Accounting
Principles to Mutual Life Insurance and Other Enterprises" (Interpretation). The
Interpretation, as amended, is effective for 1996 annual financial statements
and thereafter, and will require life insurance companies to adopt all
applicable authoritative GAAP pronouncements in any general-purpose financial
statements that they may issue and describe as being in accordance with GAAP.

In January 1995, in response to Interpretation 40, the FASB issued Statement of
Financial Accounting Standards (SFAS) No. 120, "Accounting and Reporting by
Mutual Life Insurance Enterprises and by Insurance Enterprises for Certain
Long-Duration Participating Contracts." This Statement effectively establishes
generally accepted accounting principles, which are different from statutory
accounting principles, for mutual life insurance companies. Through December 31,
1995, statutory accounting practices were considered to be generally accepted
accounting principles for mutual life insurance companies.

SFAS No. 120 is effective for financial statements issued for fiscal years
beginning after December 15, 1995. Because the accompanying financial statements
of GBO have been prepared in conformity with GAAP for stock life insurance
companies, the adoption of the new pronouncements that define GAAP for mutual
life insurance companies is not expected to have a material effect on GBO's
results of operations or statements of assets and liabilities.

                                        2    


<PAGE>   3
In March 1995, the FASB issued SFAS No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed Of." This Statement
requires that long-lived assets and certain identifiable intangibles to be held
and used by an entity be reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable. In those cases where it is determined that the carrying amount is
not recoverable, an impairment loss is recognized (the difference between the
cost and fair value of the asset). The Statement also requires long-lived assets
to be disposed of (e.g., real estate held for sale) to be carried at the lower
of cost or fair value less cost to sell and does not allow such assets to be
depreciated. This Statement is effective for 1996 financial statements. The
adoption of SFAS No. 121 is not expected to have a material effect on GBO's
results of operations or statements of assets and liabilities.

SFAS No. 125 "Accounting for Transfers and Servicing of Financial Assets and
Extinguishments of Liabilities" was issued in June 1996, and is not expected to
have a material effect on GBO's results of operations or statements of assets
and liabilities.

POSTEMPLOYMENT BENEFITS

Effective January 1, 1994, GBO adopted SFAS No. 112 "Employers' Accounting for
Postemployment Benefits," and established a liability for the costs and
obligations of benefits such as severance, disability, life insurance, and
health care to be paid to inactive or former employees. A transition obligation
of $2,910 thousand, net of taxes of $1,567 thousand, was recognized upon
adoption.

RECEIVABLE FROM JOHN HANCOCK

GBO is not a separate legal entity and does not have specifically identifiable
cash or investments. The receivable from John Hancock included in the
accompanying combined statements of assets and liabilities represents the
difference between GBO operating business assets and liabilities. It does not
bear a stated rate of interest. However, investment income is allocated to GBO
based on the portfolio investment income of the underlying general account
assets of John Hancock that support GBO's business. This Agreement provides for
the monetization of this receivable at Closing.

REVENUE RECOGNITION

Insurance premiums on fully insured and partially funded contracts are earned on
a pro-rata basis over the period in which services are obligated to be provided.
The portion of premiums not earned at the end of the period is recorded as
unearned insurance premiums.

Administrative service fees are earned on a pro-rata basis as the services are
performed.

                                       3



<PAGE>   4
DIVIDENDS

Dividends for eligible contracts are based on premiums received in excess of
claims and expenses incurred. The dividend liability for completed policy years
is established based on policy year experience, while dividends for incomplete
policy years are established based on experience through the financial statement
date.

INCOME TAXES

John Hancock and certain of its affiliates, including the GBO operations, file a
consolidated federal income tax return. However, because GBO is not a separate
legal entity, a formal tax allocation agreement between John Hancock and GBO has
not been executed. For purposes of these financial statements, GBO has been
treated as a separate business of a mutual life insurance company for the
determination of the tax provision. Accordingly, income tax benefit is allocated
to GBO at 35% and is settled currently through the receivable from John Hancock.
The gross asset and liability balances relating to the future tax consequences
of temporary differences between the financial reporting and tax basis of assets
and liabilities are recorded at the John Hancock consolidated level. An equity
tax, applicable to mutual life insurance companies, has not been included in the
provision.

INTANGIBLE ASSETS

Intangible assets, which include noncompete agreements, long-term employment
contracts, capitalized software and other intangibles, are amortized using the
straight-line method over their estimated useful lives, which range from two to
forty years. Accumulated amortization was $18,253 thousand and $13,643 thousand
at December 31, 1995 and 1994, respectively.

PROPERTY, EQUIPMENT AND LEASEHOLD IMPROVEMENTS

Property and equipment, principally composed of furniture and equipment, are
reported at depreciated cost. Depreciation is computed using the straight-line
method based upon the estimated useful lives of the assets. Leasehold
improvements are depreciated over the shorter of the lease term or the estimated
useful life.

FUTURE POLICY BENEFITS AND EXPENSES

Future policy benefits for group life and accident and health contracts have
been computed using interest rates ranging from 2.5% to 8.42%, and mortality,
morbidity, and withdrawal assumptions based on GBO's experience and industry
standards.

Liabilities for unpaid claims and claim expenses include estimates of payments
to be made on reported life and accident and health insurance claims and
estimates of incurred but not reported claims based on historical claims
development patterns.

                                        
                                       4



<PAGE>   5
Estimates of future policy benefit reserves, claim reserves and expenses are
reviewed continually and adjusted as necessary; such adjustments are reflected
in current operations. Although considerable variability is inherent in such
estimates, management believes that future policy benefit reserves, claim and
expense reserves are adequate.

PAYABLE TO AFFILIATE

Payable to affiliate represents the amount due to John Hancock principally as a
result of intercompany expense allocations.

REINSURANCE

All assets and liabilities related to reinsurance ceded contracts are reported
on a gross basis in the accompanying statements of assets and liabilities. The
accompanying statements of operations reflect premiums, benefits and expenses
net of reinsurance ceded.

GBO assumes and cedes reinsurance and participates in various pools and
associations. The portion of risks that exceeds GBO's retention limits is
reinsured with other insurers. GBO also obtains other reinsurance coverages with
retentions and limits that management believes are appropriate for the
circumstances. Those reinsurance agreements provide for greater diversification
of business, allow management to control exposure to potential losses arising
from large risks and provide additional capacity for growth. Amounts recoverable
from reinsurers are estimated in a manner consistent with the future policy
benefit and claim liabilities associated with the reinsured policies.

Reinsurance premiums, commissions, expense reimbursements, benefits and reserves
related to reinsured business are accounted for on bases consistent with those
used in accounting for original policies issued and the terms of the reinsurance
contracts.

RESTRUCTURING CHARGES

In 1994, the GBO recorded a $34,722 thousand restructuring charge in accordance
with its plans to reduce its cost structure and consolidate operations. This
charge included accruals for severance and related benefits for staff
reductions, property lease terminations, and the write-off of certain assets.
The restructuring liability is settled through the receivable from John Hancock.
The remaining balance of the restructuring liability at December 31, 1995 and
1994 was $7,915 thousand and $23,362 thousand, respectively. The majority of the
remaining balance relates to deferred benefits for terminated employees and
leases.

NOTE 5--RELATED PARTY TRANSACTIONS

The various related party transactions between John Hancock and GBO are
summarized below:

OPERATING EXPENSES: John Hancock provides GBO with personnel, property and
facilities including certain services such as investment management, legal,
financial and administrative support. GBO is charged for these services
utilizing various methods of expense allocation which are primarily based on
time incurred, ratios of direct and indirect expenses, square footage occupied,
or allocated in pro rata relationship to other business units of John Hancock.
Management believes the methods used to allocate such costs are reasonable.
Operating expenses allocated to GBO amounted to $189,883 thousand and $193,060
thousand in 1995 and 1994, respectively.

Investment Income and Receivable from John Hancock: GBO is not a separate legal
entity and does not have specifically identifiable cash or investments. The
receivable from John Hancock included in the accompanying combined statements of
assets and liabilities represents the difference between GBO operating business
assets and liabilities. The fair value of the receivable from John Hancock
approximates its carrying value at December 31, 1995 and 1994.

GBO is allocated investment income based on the portfolio income of the
underlying general account assets of the John Hancock that support GBO's
business. Investment income allocated to GBO was $35,374 thousand and $41,040
thousand in 1995 and 1994, respectively.

BENEFIT PLANS: Eligible employees of John Hancock participate in various types
of pension plans sponsored by John Hancock which include defined benefit,
defined contribution and nonqualified plans. Pension benefits under the defined
benefit plans are based on years of service and average compensation, generally
during the five years prior to retirement. John Hancock's funding policy for
qualified defined benefit plans is to contribute annually an amount in excess of
the minimum annual contribution required under the Employee Retirement Income
Security Act (ERISA). This amount is limited by the maximum amount that can be
deducted for federal income tax purposes. Plan assets consist principally of
listed equity securities, corporate obligations and U.S. government securities.
GBO is allocated its proportionate share of expense based on John Hancock's
intercompany expense allocation methodology. John Hancock also has various
defined contribution plans, nonqualified plans and additional compensation plans
covering its employees and agents. GBO is allocated a share of the expenses
related to the plans pursuant to John Hancock's intercompany expense allocation
methodology. John Hancock also provides certain life and accident and health
insurance benefit plans covering most of its retired employees and general
agency personnel. GBO is allocated its proportionate share of these expenses.

Total benefit plan expense allocated to GBO was $14,186 thousand and $14,515
thousand for 1995 and 1994, respectively.


                                       6



<PAGE>   7
GBO has issued certain group life and accident and health insurance contracts to
cover employees of John Hancock. Premiums, benefits (including the provision for
future benefits), and reserves included in the combined statements of operations
and changes in net asset balance and combined statements of assets and
liabilities associated with the coverage approximates $23,978 thousand, $24,154
thousand, and $53,706 thousand, in 1995, respectively. The corresponding amounts
in 1994 were $18,903 thousand, $19,487 thousand, and $59,270 thousand,
respectively.

        (2)       the following reserve development procedures and methods used
                  with respect to the GBO Included Business Reserves as of the
                  Closing Date:

                                GENERAL COMMENTS

The reserve development processes described here were those used to establish
12/31/93 through 12/31/95 reserves. The 1996 reserves were established using the
same methods, which were consistently applied throughout the period. Knowledge
of exceptional and unusual circumstances is taken into account when reserves are
established ( e.g., when a known claim has not yet been entered into the
reporting system). However, certain situation specific reserves have been
released during 1995 and 1996 and are summarized herein.

Two distinct valuation methods are generally accepted actuarial practice as
described in ASOP #5. Each of these methods are applied to appropriate
liabilities described herein. The two methods are developmental and seriatim
(tabular). The developmental method reflects emerging experience from prior
periods, while the seriatim method is based on defined mortality or morbidity
tables and valuation interest rates.

Unless otherwise noted, GAAP and statutory reserves are equal. Valuation bases
as of 12/31/95 are shown in Exhibit 1 for statutory and GAAP reserves that
differ. Prior to 1995, SIB reserves for GBS and Association on a GAAP basis were
a mixture of statutory and tax valuation bases. This change increased the GAAP
reserves by $800,000.

Completion analysis and annual factor development are all based on 12/31/XX
runouts. This process ignores possible seasonality in generating reserves.

With the exception of Ford reserves, the triangulation reserves, the life IBNR
and the AD&D IBNR are all developed using claim data up to the end of the month
preceding the valuation date; i.e., December 31, reserves are developed from
claims paid up to November 30th. Ford reserves are based on data through the end
of the valuation month.

                  LIFE INSURANCE RESERVES (EXHIBITS 8, 10 & 11)

GROUP PAID-UP LIFE INSURANCE

These are paid-up life insurance benefits issued in accordance with group
paid-up life policies. Benefits are payable upon death of the insured. The
amount of individual benefits is determined by incremental purchases of paid-up
coverage over the years the group plan has been inforce. Reserves are determined
by a seriatim reserve calculation. The valuation basis differs according to the
issue years of each increment of paid-up coverage. There are five different
reserve bases (see Exhibit 1) depending on year of issue. Cash surrender values
are available under the terms of the paid-up certificates. These surrender
values are only available after an employee leaves the active employment of the
group policyholder.

GROUP UNIVERSAL LIFE INSURANCE

These are life insurance benefits issued under a group universal life-type plan.
Individual account balances are used to provide insurance for death benefits.
The death benefit varies according to the terms of the plan and the amounts
contributed by individual enrollees. Seriatim reserves are established equal to
the individual account balances. Account balances are available as cash
surrender values.

WAIVER OF PREMIUM BENEFITS

These benefits provide for continuation of Group Life coverage to disabled
individuals under the terms of their group life insurance plan. The period for
which coverage is continued and the amount of coverage vary according to the
terms of the plan. Benefits are payable upon the death of the insured during the
period of disability. Reserves are established upon disability. There are no
surrender options, and benefits cannot be commuted. This is a seriatim reserve
calculation for reported waiver claims. There are four different statutory
reserve bases (see Exhibit 1) depending on year of disability. There are
thirteen different GAAP reserve bases (see Exhibit 1) depending on year of
disability.

The reserve for unreported claims is on the developmental method using annual
(as opposed to monthly or quarterly) lags, with completion assumed after four
years. The completion factors are applied to premium for the most recent year
and to reserves for the prior three years.

LIFE UNEARNED PREMIUM RESERVE

The reserve is the prorata portion of premiums between the valuation date and
the next premium due date.


                                       8



<PAGE>   9
SURVIVOR INCOME (SIB) BENEFITS

(SUPPLEMENTARY CONTRACTS WITH LIFE CONTINGENCIES)

These contracts are immediate annuities issued to a surviving spouse or the
children of a plan participant upon the death of the participant in certain
group plans. The terms of the annuities vary according to the group plan. While
some of the contracts are guaranteed for life, some are for a limited period
such as two years or until the spouse reaches a specified age such as
sixty-five. Under certain group plans, the remarriage of the annuitant
disqualifies the annuitant from receiving further benefits. All of these
contracts involve life contingencies.

The amount of the benefit also depends on the particular group coverage. In some
cases, the benefit is fixed at issue and does not change. In some cases, part of
the benefit is attributed to surviving children of the participant and decreases
upon a child's attainment of a specified age, such as 18 or 21. Some group
contracts offset the annuity benefit for Social Security.

Annuity payments are made monthly. Reserves are established when the annuity
begins, upon the death of a covered plan participant. There are no surrender
options under these contracts, and benefits cannot be commuted. The reserve for
established claims is a seriatim calculation. There are six statutory reserve
bases (see Exhibit 1) depending on date of death. There are six GAAP valuation
bases (see Exhibit 1) depending on date of death and type of benefit.

The reserve for unreported claims is developed from annual lags, with the
completion assumed in one year, and with the completion factor applied to
reserve. The factor used is the higher of the most recent years completion
factor and the average of the last three years' factors.

SUPPLEMENTARY CONTRACTS WITHOUT LIFE CONTINGENCIES

These are monthly annuity benefits payable to survivors as a result of the death
of an insured under certain group term life plans. Certain approved Permanent
and Total Disability benefits in payment status are also included. Benefit
amounts and payment durations vary. No contingencies are involved, so the
reserve is simply future benefits discounted for interest. The interest rates
for the survivor benefits, which are the bulk of the reserves, are 8% from 1985
to 1992, 5% for 1993 & 1994 and 6% for 1995. This is a seriatim calculation.
There are no unreported claims.

PERMANENT AND TOTAL DISABILITY (PTD) BENEFITS

These are monthly benefits payable to disabled individuals for a fixed period,
which reduce the death benefit otherwise provided by the insured's group life
plan. The benefit amounts and payment periods vary according to the terms of the
plan. Reserves are established upon disability. There are no surrender values.
Remaining benefit payments may be commuted upon the death of the disabled
insured. This is a seriatim calculation for reported disability claims. There
are two reserve bases (see Exhibit 1) depending on when disability began.


                                       9


<PAGE>   10
The reserve for unreported claims is based on the development method. The bulk
of this reserve is for the Ford case, where PTD coverage eligibility follows a
period on LTD. The reserve for unreported claims for Ford arises from the one
year waiting period for LTD, and is estimated from prior years' incurrals.

LIFE PENDING CLAIM RESERVE

This is a reserve for reported life claims that have not been paid. The reserve
is equal to the sum of these claims. Resisted claims are included at 50% of
amount of claim based on historical experience.

LIFE INCURRED BUT NOT REPORTED CLAIM RESERVE

This is a reserve for death claims where death has occurred but claim has not
been reported. The development method reserve is calculated as a factor
multiplied by last three months paid claims. The factor is developed from prior
years run-out. For each year a factor equal to run-out divided by last three
months paid claims from preceding year is developed. The factor used is the
greater of the most recent years factor, or the factor equal to average of last
three years factors.

GUARANTEED ACCESS ACCOUNTS

These are death benefits under certain group life plans which have been left on
deposit with the company. Beneficiaries may withdraw amounts at any time by
writing checks against their account balances. Liabilities equal the account
balances.

DIVIDENDS TO ACCUMULATE

These are policyholder dividends which are left on deposit with the Company.

                      A&H CLAIM RESERVES (EXHIBITS 9 & 11)

AD&D PENDING

This is a reserve for reported AD&D claims that have not been paid. The reserve
is equal to the sum of these claims. Resisted claims are included at 50% of
amount of claim based on historical experience.

AD&D INCURRED BUT NOT REPORTED

This is a reserve for AD&D claims where death has occurred but claim has not
been reported. The development method reserve is calculated as a factor
multiplied by last 12 months paid claims. The factor is developed from prior
years run-out. For each year a factor equal to run-out divided by last calendar
year's paid claims is developed. The factor used is the greater of the most
recent years factor, or the factor equal to average of last three years factors.

                                       10


<PAGE>   11
TRIANGULATION RESERVES

These reserves are for short term disability, dental and medical coverages and
group conversion. The developmental reserves are determined from last three
years experience by the triangulation method. Exhibit 2 shows which triangles
are developed. Claims are divided by incurral month, with completion factors
developed for each month. Judgmental adjustments are made to reflect special
circumstances such as large claims or extra backlog, and for the most recent
months where credible runout is not yet available. The reserve for all medical
coverages has a 5% load for extended benefits.

LONG TERM DISABILITY (LTD) BENEFITS

These benefits are payable monthly to disabled individuals under the terms of
group LTD plans. Some plans pay benefits to a specified age such as sixty-five,
or according to a fixed duration schedule, during the continuance of disability
as defined in the plan. Benefit amounts depend on the particular group plan, and
are usually offset for Social Security. Benefits are payable monthly after an
elimination period which varies by group plan. Reserves are established upon
disability (considering Incurred and Unreported reserves). The reserves are
based on a seriatim calculation. There are three valuation bases (prior to
7/1/84 6% with 64 CDT: 7/1/84 - 12/31/92 7.5% with 64 CDT and 1/1/93 and later
5% with 87 GLTD with modification for first 2 years). The development reserve
for incurred but not reported claims is based on completion factors from the
last four completed years. All claims are assumed to be reported in three years,
so the completed years used are the current year minus six through current year
minus three. Annual lag periods are used, with completion factors applied to
reserves.

A&H UNEARNED PREMIUM RESERVE

This reserve is the prorata portion of premium between the valuation date and
the next premium due date.

SPECIAL RESERVES

Stoploss - This reserve is for pending and IBNR claims under stoploss coverages.
Pending claims are based on actual reported claims while IBNR claims are
estimated using loss ratios from historical experience for prior year incurrals
and pricing loss ratios for the current year incurrals. The loss ratio times
earned premium minus reported claims equals the unreported reserve.

Mini Excess - This reserve is for amounts owed to Minimum Premium or Planned
Funding clients as a result of actual claims exceeding the claim liability limit
to date.

Group Health Conversions - This reserve is for expected future losses under the
group conversion line due to inadequate premium. The reserve equals 40% of
future projected premiums, currently discounted at 6.25%.

                                       11

<PAGE>   12
Supp State Plans- This reserve is for assessments under supplemental state
disability plans under New York and New Jersey and is determined by applying a
factor (5% for NY and 10% for NJ) to the premium earned for those states.

Missing Tapes - This reserve is for known health claims not yet recorded on our
claim system due to late submission of claim tapes from Third Party
Administrators.

FASCO / Hackett - This reserve is for pending and IBNR claims under special
reinsurance arrangements. Loss ratios are used for the most recent 12 month
period, with completion factors for prior periods. Reserves are based on monthly
reporting periods for FASCO and quarterly for Hackett. These reserves are 95%
ceded. This reserve can fluctuate due to the delay in reporting paid claims.

Mini Terminal Premium - This reserve is the reserve held for Minimum Premium or
Planned Funding clients who have chosen to deposit reserve funds with John
Hancock.

Litigation - This was for possible loss in a litigation in the FASCO case. This
reserve was released during 1996 as a result of favorable court ruling.

AIDS - This reserve was initially established to cover claims due to AIDS. The
life reserve was released in 1995 and the health reserve in 1996 as our general
IBNR reserves have been shown to be adequate without the inclusion of an
additional reserve.

Two Year Average - This reserve was for possible additional A&H lag claims not
projected by the triangulation runout factors. This reserve was released during
1995 since our general IBNR claims have been shown to be adequate.

A&H Resisted Claims - This reserve is for A&H resisted claims.

                                OTHER LIABILITIES

CLAIM STABILIZATION RESERVES (CSRS)

These are amounts held under certain group life and/or A&H contracts to provide
for contingencies of claim fluctuation. CSR liabilities are subject to
withdrawal upon the termination of their associated policies, or earlier as an
additional dividend payment.

DIVIDENDS DUE & UNPAID AND APPORTIONED

For participating group policyholders, dividends are the difference between
earned premium and all incurred claims and expenses. The reserves used in the
dividend liability estimate are dividend basis reserves (see Exhibit 1).

Liabilities for Due & Unpaid dividends are determined for completed policy years
for participating group policyholders. Apportioned dividend liabilities are
estimated based on incomplete policy years.
