            THE MANUFACTURERS LIFE INSURANCE COMPANY OF NORTH AMERICA
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               SEPTEMBER 30, 1999
                                   (UNAUDITED)



1.       BASIS OF PRESENTATION

         The accompanying unaudited consolidated financial statements of the
         Company and its wholly-owned subsidiaries have been prepared in
         accordance with generally accepted accounting principles ("GAAP"),
         except that they do not contain complete notes. However, in the opinion
         of management, these statements include all normal recurring
         adjustments necessary for a fair presentation of the results. These
         financial statements should be read in conjunction with the financial
         statements and the related notes included in the Company's annual
         report on Form 10-K for the year ended December 31, 1998. Operating
         results for the nine months ended September 30, 1999 are not
         necessarily indicative of the results that may be expected for the full
         year ending December 31, 1999.

         Certain 1998 balances have been reclassified to permit comparisons with
         the 1999 presentations.

2.       RECENT ACCOUNTING STANDARDS

         In June 1998, the Financial Accounting Standards Board (FASB) issued
         Statement No. 133, "Accounting for Derivative Instruments and Hedging
         Activities" (FAS 133). FAS 133 establishes accounting and reporting
         standards for derivative instruments and for hedging activities.
         Contracts that contain embedded derivatives, such as certain insurance
         contracts, are also addressed by the Statement. FAS 133 requires that
         an entity recognize all derivatives as either assets or liabilities in
         the statement of financial position and measure those instruments at
         fair value. In July 1999 the FASB issued Statement 137 which delayed
         the effective date of FAS 133 to fiscal years beginning after June 15,
         2000. The Company is evaluating FAS No. 133 and has not determined its
         impact on results of operations and financial condition.

3.       COMPREHENSIVE INCOME

         Total comprehensive income was as follows:

         Other comprehensive income is reported net of taxes recoverable

         for the nine months ended September 30, 1999 and 1998, respectively.

4.       SEGMENT DISCLOSURES

         The Company reports three business segments: Annuities, Pensions, and
         Life Insurance. The Annuities segment consists of annuity contracts
         that provide the customer with the opportunity to invest in mutual
         funds managed by independent investment managers and the Company or in
         the general account of the Company, with investment returns
         accumulating on a tax-deferred basis. The Pensions segment offers
         401(k) products to customers in the State of New York. The Individual
         Life Insurance segment offers traditional non-participating life
         insurance to the New York State market. No significant assets or
         revenues have been generated to date in these two segments. The
         following is a summary of the contribution to net income of the three
         business segments:

Item 2. Management's Discussion And Analysis of Results of Operations And
        Financial Condition


OVERVIEW


The following analysis of the consolidated results of operations and financial
condition of The Manufacturers Life Insurance Company of North America
(hereinafter referred to as "MNA" or the "Company") should be read in
conjunction with the Consolidated Financial Statements and the related Notes to
Consolidated Financial Statements.


CORPORATE STRUCTURE AND OVERVIEW

The Company is a wholly-owned subsidiary of Manulife-Wood Logan Holding Co.,
Inc. ("MWL"). MWL is 78.4% owned by The Manufacturers Life Insurance Company
(U.S.A.) ("ManUSA") and 21.6% owned by MRL Holding, LLC ("MRL"). ManUSA and MRL
are indirectly wholly-owned subsidiaries of The Manufacturers Life Insurance
Company, which in turn is a wholly-owned subsidiary of Manulife Financial
Corporation. Manulife Financial Corporation and its subsidiaries are known
collectively as "Manulife Financial".

Manulife Financial is a leading provider of financial protection products and
investment management services to individuals, families, businesses and groups
in selected international markets. Manulife Financial operates in 16 countries
and territories worldwide, with more than 27,000 employees and agents. Funds
under management by Manulife Financial were $96.7 billion (Cdn) as of December
31, 1998 with a consolidated surplus position of $6.0 billion (Cdn).

MNA is licensed to sell fixed and variable annuities, traditional life and
variable life insurance, and accident and health insurance in all states except
New Hampshire and New York. MNA has two subsidiaries, The Manufacturers Life
Insurance Company of New York ("MNY") and Manufacturers Securities Services, LLC
("MSS"). MNY is an insurance subsidiary licensed to sell fixed and variable
annuities, traditional life insurance, and accident and health insurance in the
State of New York only. MSS, a majority-owned broker dealer, acts as investment
advisor to the Manufacturers Investment Trust ("MIT"), a no-load, open-end
management investment company organized as a Massachusetts business trust and is
the principal underwriter of the Company's variable annuity and life insurance
contracts and is the exclusive distributor of its insurance products in the
State of New York. MSS is the successor to NASL Financial Services, Inc. ("NASL
Financial"), a broker dealer that conducted operations until September 30, 1997,
when it was reorganized into MSS. Prior to October 1, 1997, NASL Financial also
acted as investment advisor to North American Funds (NAF), a no-load, open-end
management investment company organized as a Massachusetts business trust.

The Company, along with The Manufacturers Life Insurance Company, enjoys strong
financial ratings that enhance its ability to attract new sales and retain
assets. Distributors and consumers of variable and fixed annuity products have
begun to utilize the relative financial strength ratings as a criteria in
choosing an annuity carrier. The Company has received financial strength ratings
of A++ (Superior) by A.M. Best, AA+ (Very Strong) by Standards and Poor's and
Aa2 (Excellent) by Moody's Investor Services. The Company is rated AAA (Highest)
by Duff & Phelps in terms of its ability to meet contractual obligations to
policyholders.

Prior to 1998, the Company reported two segments, Annuities and Mutual Funds.
The Mutual Fund segment consisted solely of NAF, a group of thirteen mutual
funds. During 1997, the Company disposed of its Mutual Fund segment to an
unrelated party. In 1998 and 1997, pursuant to a revised plan of operations for
MNY, the Company entered the Pensions and the Life Insurance businesses in the
State of New York. The Company now reports three segments: Annuities, Pensions,
and Life Insurance. Two of the Company's segments, Pensions and Life Insurance,
are in the development stage and the assets,



                                                                               9
<PAGE>   10


revenues and operations of those segments are not material to the Company's
September 30, 1999 financial position or results of operations. The remainder of
this discussion will be limited to the Annuities segment except as noted.

The Company's primary source of earnings from the Annuities segment are fees
assessed against policyholder account balances held in the Company's separate
accounts including: mortality and expense risk charges, surrender charges, and
an annual administrative charge. In addition, the segment earns a spread between
the advisory fees charged to manage the separate account assets invested in MIT
and the subadvisory fees paid to external managers of those assets. A key factor
in the Company's profitability is sustained growth in the underlying assets
through market performance coupled with the ability to acquire and retain
variable annuity and life deposits.

REVIEW OF CONSOLIDATED OPERATING RESULTS AND CONSOLIDATED FINANCIAL CONDITION


REVIEW OF CONSOLIDATED OPERATING RESULTS


The discussion that follows compares results for the three months ended
September 30, 1999 to the three months ended September 30, 1998.


The Company recorded net income of $11.1 million in 1999 versus net income
of $2.4 million in 1998, an increase of $8.7 million or 369%. Revenues grew by
31% to $91.4 million as a result of growth in fee income earned on additional
separate account assets, increasing advisory profits associated with additional
assets in MIT, and investment income from higher general account assets.
Separate account assets at September 30, 1999 compared to September 30, 1998
were higher by $3.3 billion or 32%. The asset growth is attributed to an
increase in variable annuity sales, strong equity market performance, and
favorable contract persistency. Total sales during the third quarter of 1999
were $941 million, an increase of 41% over the same quarter in 1998. Total fees,
including advisory fees, generated by separate accounts and policyholder funds
increased by $22.0 million or 33% in 1999.

The Company incurred total benefits and expenses in 1999 of $74.3 million, an
increase of $8.3 million, or 13% compared to 1998. The additional expenses
reflect an increase in non-capitalized acquisition expenses, increasing
sub-advisory expenses associated with additional assets in MIT, and higher
financing costs which were offset by a decrease in Deferred Acquisition Costs
(DAC) amortization. The amortization of DAC was reduced by $8.7 million during
the third quarter of 1999 due primarily to improved investment performance of
the Company's Separate Account Assets compared to the third quarter of 1998. It
is this asset base against which fees are assessed. Higher projected fees due to
the quarter's results compared to that of 1998 resulted in a reduced DAC
amortization for the quarter. The Company paid an additional $4.2 million of
sub-advisory expenses during the third quarter of 1999. The Company's commission
financing loans increased by approximately $41.0 million over September 30, 1998
levels resulting in additional financing costs.


The discussion that follows compares results for the nine months ended September
30, 1999 to the nine months ended September 30, 1998.


The Company recorded net income of $36.7 million in 1999 versus net income of
$26.5 million in 1998, an increase of $10.2 million or 39%. Revenues grew by 26%
to $255.7 million as a result of growth in fee income earned on additional
separate account assets, increasing advisory profits associated with additional
assets in MIT, and investment income from higher general account assets.
Separate account assets at September 30, 1999 compared to September 30, 1998
were higher by $3.3 billion or 32%. The asset growth is attributed to an
increase in variable annuity sales, strong equity market performance, and
favorable contract persistency. Total sales during the first nine months of 1999
were $2.4 billion, an increase of 33% over the same period in 1998. Total fees,
including advisory fees, generated by separate accounts and policyholder funds
increased by $53 million or 27% in 1999.

The Company incurred total benefits and expenses in 1999 of $198.8 million, an
increase of $36.8 million, or 23% compared to 1998. The additional expenses
reflect an increase in non-capitalized acquisition expenses, increasing
sub-advisory expenses associated with additional assets in MIT, and higher
financing costs. The amortization of DAC was reduced by $4.9 million during 1999
due primarily to improved investment performance of the Company's Separate
Account Assets compared to same period in 1998. It is this asset base against
which fees are assessed. Higher projected fees due to the quarter's results
compared to that of 1998 resulted in a reduced DAC amortization for the quarter.
The Company paid an additional $9.0 million of sub-advisory expenses during the
first nine months of 1999. The Company's commission financing loans increased by
approximately $41.0 million over September 30, 1998 levels resulting in
additional financing costs. Offsetting this increase in financing costs were the
effects of the Company's reinsurance treaties, which lowered the overall
financing costs for the period.


CONSOLIDATED FINANCIAL POSITION

September 30, 1999 compared to December 31, 1998

Total assets increased from $13.5 billion at December 31, 1998 to $15.3 billion
at September 30, 1999, an increase of $1.8 billion or 13%. Separate account
assets increased by 12% over the first nine months of 1999 and represent 90% of
total assets as the Company continues to focus on its variable option annuity
products. The Company continues to own only investment grade fixed maturity
investments to support its general account liabilities and shareholder's equity.
The Company's DAC asset grew by 28% as the Company experienced increased annuity
sales volumes during the first nine months of 1999. The Company deferred the
related costs, net of current amortization, associated with those sales.

Total liabilities have increased proportionately with the growth in the related
assets, primarily in the Company's separate accounts. During the first nine
months of 1999, the Company borrowed an additional $41.0 million from The
Manufacturers Life Insurance Company to support its sales volumes and related
acquisition expenses.

The growth in retained earnings is primarily due to net income from operations
of $36.7 million. The Company's shareholder's equity decreased by $3.0 million
due to lower market values associated with invested assets at September 30,
1999.

MARKET RISK

Market risk is the risk that the Company will incur losses due to adverse
changes in market rates and prices. The primary market risk exposure for the
Company is the impact of lower than expected equity market performance on its
asset-related fee revenue. The Company also has certain exposures to changes in
interest rates.

The Company earns asset based fees on the asset levels invested in the separate
accounts. As a result, the Company is subject to equity risk and the effect
changes in equity market levels will have on the amounts invested in the
separate accounts.

Interest rate risk is the risk that the Company will incur economic losses due
to adverse changes in interest rates. This risk arises from the issuance of
certain interest sensitive annuity products and the investing of those proceeds
in fixed rate investments. The Company manages its interest rate risk through an
asset/liability management program. The Company has established a target
portfolio mix which takes into account the risk attributes of the liabilities
supported by the assets, expectations of market performance, and a generally
conservative investment philosophy. Preservation of capital and maintenance of
income flows are key objectives of this program. In addition, the Company has
diversified its product portfolio offerings to include products that contain
features that will protect it against fluctuations in interest rates. Those
features include adjustable crediting rates, policy surrender charges, and
market value adjustments on liquidations.

Based on the Company's overall exposure to interest rate and equity price risks,
the Company believes that changes in market rates would not materially affect
the consolidated near-term financial position, results of operations or
cashflows of the Company as of September 30, 1999. Refer to the Company's Annual
Report on form 10-K for a more detailed discussion of market risks.


IMPACT OF YEAR 2000

The Company makes extensive use of information systems in the operations of its
various businesses, including for the exchange of financial data and other
information with customers, suppliers and other counterparties. The Company also
uses software and information systems provided by third parties in its
accounting, business and investment systems.

The Year 2000 risk, as it is commonly known, is the result of computer programs
being written using two digits, rather than four, to define the applicable year.
Any of the Company's computer programs that have date-sensitive software may
recognize a date using "00" as the year 1900 rather than the year 2000. This
could result in systems failures or miscalculations causing disruptions of
operations, including, among other things, a temporary inability to process
transactions, send premium billing notices, make claims payments or engage in
other normal business activities.

The systems used by the Company have been assessed as part of a comprehensive
written plan conducted by the Company's ultimate parent company, Manulife
Financial Corporation, on behalf of all of its subsidiaries, to ensure that the
computer systems and processes of all of the Manulife Financial companies,
including the Company's, will continue to perform through the end of this
century and in the next.











                                                                              13
<PAGE>   14


In 1996, in order to make Manulife Financial's systems Year 2000 compliant, a
Project was instituted to modify or replace both Manulife Financial's
information technology systems ("IT systems") and embedded technology systems
("Non-IT systems"). The phases of this Project include (i) an inventory and
assessment of all systems to determine which are critical, (ii) planning and
designing the required modifications and replacements, (iii) making these
modifications and replacements, (iv) testing modified or replaced systems, (v)
redeploying modified or replaced systems and (vi) final management review and
certification.

Management believes that the certification phase was completed for all the
Company's critical IT and Non-IT systems as of June 30, 1999. Management
believes that the Company's non-critical systems were Year 2000 compliant by the
end of the first quarter 1999.

In addition to efforts directed at the Company's own systems, Manulife Financial
consulted vendors, customers, borrowers and other third parties with which the
Company deals in an effort to ensure that no material aspect of the Company's
operations will be hindered by Year 2000 problems of these third parties. This
process included sending questionnaires to third parties regarding the state of
their Year 2000 readiness and, where possible or where appropriate, conducting
further due diligence activities. Where appropriate, risk management steps are
being followed as a result of the third-party assessment.

The Year 2000 Project Management Office for Manulife Financial's U.S. Division
has coordinated the preparation and completion of contingency plans on behalf of
U.S. Division affiliates and subsidiaries, including the Company, in the event
that Manulife Financial's Year 2000 Project has not fully resolved its Year 2000
issues.

Management believes that, due to the modifications made to existing software and
conversions to new software, the Year 2000 risk will not pose significant
operational problems for the Company's computer systems. As part of the Year
2000 Project, critical systems were "time-shift" tested in the year 2000 and
beyond to confirm that they will continue to function properly before, during
and after the change to the year 2000. However, there can be no assurance that
Manulife Financial's Year 2000 Project, including consulting third parties and
its contingency planning, will avoid any material adverse effect on the
Company's operations, customer relations or financial condition.

Manulife Financial estimates the total cost of its Year 2000 Project will be
approximately $60.5 million,* of which $58.7 million* has been incurred through
September 30, 1999. In addition, previously unbudgeted costs associated with the
start up of a new joint venture in Japan in April 1999 are estimated to be $5.0
million,* of which approximately $3.2 million* was incurred through September
30, 1999. These previously unbudgeted costs will be shared by Manulife Financial
and its joint venture partner. There can be no assurance that the actual costs
incurred will not be materially higher than estimated. Manulife Financial's Year
2000 costs were $12.5 million* for the first nine months of 1999, including the
total joint venture costs, and $26.4 million* for the first nine months of 1998.
Most costs will be expensed as incurred; however, those costs attributed to the
purchase of new software and hardware will generally be capitalized.

* All figures are shown in US dollars  converted from Canadian  dollars using
  the average  exchange rate of 1.490 in effect  September 30, 1999.
