                   Profile Of Pia Variable Annuity Account I

This profile is a summary of some of the more important points that you should
consider and know before purchasing the Contract. The Contract is more fully
described in the prospectus which accompanies this Profile. Please read the
prospectus carefully.


     1. The Annuity Contract
     ------------------------------------------
        The Contract offered in this prospectus is a combination variable and
     fixed annuity contract between you, the owner, and The Penn Insurance and
     Annuity Company. The Contract provides a means for you to invest in one or
     more of the available investment funds listed in Section 4, and/or one or
     more of the fixed interest accounts guaranteed and funded by The Penn
     Insurance and Annuity Company through its general account.

        You determine (1) the amount and frequency of purchase payments, (2) the
     investment funds, (3) transfers between the investment funds, (4) the type
     of annuity to be paid after the accumulation period, (5) the beneficiary to
     whom death benefits are to be paid, and (6) the amount and frequency of
     withdrawals.

        Purchase payments and investment gains allocated to the variable
     accounts vary up and down with the investment experience of the underlying
     investment funds. The investment risk is high or low, depending on the
     variable account selected. Refer to section 8 to see calendar year
     performance of the investment funds which will show you the range of
     historical returns.


     2. Annuity Payments
     ------------------------------------------
        You may choose (1) an annuity for a specified number of years, (2) a
     life annuity, (3) a life annuity with payments guaranteed for 10 or 20
     years, (4) a joint and survivor life annuity or (5) another form of an
     annuity that we may agree upon. You may select any one of these as a
     variable annuity (except for a specified number of years), a fixed annuity,
     or a combination of both.


     3. Purchase
     ------------------------------------------
        The Contract may be purchased by individuals, corporations and other
     business associations. It may be purchased under retirement plans that
     qualify for special tax treatment under the Internal Revenue Code
     (Qualified Plan), or as a Non-Qualified Plan. The minimum initial purchase
     payment is $5,000 for all Non-Qualified Plans and $2,000 for Qualified
     Plans. For both Plans, the minimum subsequent purchase payment is $250.


     4. Investment Options

     5. Expenses
     ------------------------------------------
        Each year we deduct a contract administration charge of the lesser of
$30 or 2% of the variable account value, unless the variable account value is
greater than $50,000. We deduct a daily mortality and expense risk charge equal
to an annual rate of 1.25% of the daily net asset value of the variable account
and a daily administration charge equal to an annual rate of 0.15% of the daily
net asset value of the variable account. The investment funds underlying the
variable accounts also incur expenses, which range from 0.28% to 1.75% of the
fund's average daily value.

        A contingent deferred sales charge may be deducted if you make a full or
partial withdrawal. No deferred sales charge will be made on the portion of the
first withdrawal of each contract year that does not exceed 15% of total
purchase payments. The following table shows the schedule of the contingent
deferred sales charge that will apply:

        The following table is designed to help you understand the charges in
your Contract. The column "Total Annual Charges" shows the annual percentage
charge for contract administration (which is represented as .05%), insurance
charges and investment charges. The next columns show you two examples of the
charges, in dollars, you would pay under your Contract. The examples assume that
you invested $1,000 in a Contract which earns 5% annually and that you withdraw
your money at the end of the applicable period. The premium tax is assumed to be
0% in both examples.

     6. Taxes
     --------------------------------

        Your gains under the Contract are not taxed until you take them out. If
     you take money out, earnings come out first and are taxed as income. If you
     are younger than 59 1/2 when you take money out, you may be charged a 10%
     federal tax penalty on the earnings. Payments during the income phase are
     considered partly a return of your original investment. That part of each
     payment is not taxable as income.

     7. Withdrawals
     --------------------------------

        You may withdraw all or part of your money at any time during the
     accumulation phase. Once in each contract year on or after the last day of
     the first contract year you may withdraw up to 15% of the total purchase
     payments free of the contingent deferred sales charge. A premature
     withdrawal charge may be deducted from the money earned on the fixed
     interest accounts if you take the money prior to maturity of your fixed
     interest account.

     8. Performance
     --------------------------------

        The value of your Contract will fluctuate depending upon the investment
     performance of the fund(s) you choose. The following chart shows total
     returns for each fund for the time periods shown. These numbers reflect the
     insurance company charges and the investment charges of the fund, but do
     not reflect any withdrawal charges, which would reduce the performance if
     they were applied. Past performance is no guarantee of future results.

     9. DEATH BENEFIT
     --------------------------------

        If you die prior to the Annuity Date we will pay the beneficiary the
     greatest of (1) the Contract Value for the period that proof of death is
     received, (2) the sum of the Fixed Account Value (if any) on the date that
     proof of death is received and the net purchase payments and transfers
     allocated to the Separate Account, or (3) if the contract owner dies before
     age 80, an enhanced death benefit.

        If you die after the Annuity Date, the beneficiary may elect to have the
     payments continue for the specified or guaranteed period of to receive in
     lump sum the present value of the remaining payments.

  In addition, you may also invest in fixed interest options in the Fixed Ac-
count. The fixed interest options are funded through and are backed by the
Company's general account.
  For many persons, a combination variable and fixed annuity contract may be an
attractive long-term investment vehicle. Its benefits include the manner in
which earnings on accumulated funds are taxed, the availability of multiple in-
vestment options, and the provision of annuity and death benefit guarantees.
  The Contract is not intended as a short-term investment vehicle. Early with-
drawals of purchase payments from the Contract may be subject to a contingent
deferred sales charge of up to 6%, and withdrawals by an owner before age 59
1/2 may be subject to a 10% additional income tax.
  For contracts sold in some states, not all Funds or fixed interest options
are available. Also, in some states, the number of years during which purchase
payments may be made to the Company is limited.
  A Contract may be returned within ten days of receipt for a full refund of
the Contract Value (or purchase payments, if required under applicable law).
Longer free look periods apply in some states.
  This prospectus sets forth concisely the information a prospective investor
should know before investing. It should be retained for future reference.

*** Neuberger & Berman Advisers Management Trust (the "Trust") is divided into
    portfolios ("Portfolios"), each of which invests all of its net investable
    assets in a corresponding series ("Series") of Advisers Managers Trust.
    Expenses in the table reflect expenses of the Portfolios and include each
    Portfolio's pro rata portion of the operating expenses of each Portfolio's
    corresponding Series. The Portfolios pay Neuberger & Berman Management
    Inc. ("NBMI") an administration fee based on the Portfolio's net asset
    value. Each Portfolio's corresponding Series pays NBMI a management fee
    based on the Series' average daily net assets. Accordingly, this table
    combines management fees at the Series level and administration fees at
    the Portfolio's level in a unified fee rate. Total Annual Expenses for
    each portfolio have been restated based upon current administration fees
    for the Portfolio and management fees for its corresponding Series. See
    "Expenses" in the Trust's Prospectus.

  The financial statements of the Separate Account for the year ended December
31, 1996 are included in the statement of additional information referred to on
the cover page of this prospectus.
  In advertisements of the Contracts, Penn Mutual may provide information on
total return performance and on annual changes in accumulation unit values. We
may also provide information on "yields" and "effective yields" on investments
in the Money Market Fund subaccount.
  Information on total return performance will include average annual rates of
total return for one, five and ten year periods, or lesser periods depending on
how long the subaccount has been in existence. Average annual total return fig-
ures will show the average annual rates of increase or decrease in investments
in the subaccounts, assuming a $1,000 investment at the beginning of the peri-
od, withdrawal of the investment at the end of the period, and the deduction of
all applicable charges. We may also show average annual rates of total return,
assuming other amounts invested at the beginning of the period and no with-
drawal at the end of the period. Average annual total return figures which as-
sume no withdrawal at the end of the period will reflect all recurring charges,
but will not reflect the contingent deferred sales charge (if applicable, the
contingent deferred sales charge would reduce the amount that may be withdrawn
under the Contracts).
  The "yield" on an investment in the Money Market Fund subaccount refers to
the income generated by the investment over a 7-day period. This income is then
annualized. That is, the amount of income generated by the investment during
that week is assumed to be generated each week over a 52-week period and is
shown as a percentage of the investment. The "effective yield" is calculated
similarly but, when annualized, the income earned by an investment in the
subaccount is assumed to be reinvested. The effective yield will be slightly
higher than the yield because of the compounding effect of this assumed
reinvestment.

THE PENN INSURANCE AND ANNUITY COMPANY
 
The Penn Insurance and Annuity Company (the "Company") is a Delaware stock life
insurance company. The Company is a wholly-owned subsidiary of The Penn Mutual
Life Insurance Company ("Penn Mutual"), a Pennsylvania mutual life insurance
company that has been in the life insurance business since 1847. The Company is

- --------------------------------------------------------------------------------
THE SEPARATE ACCOUNT
 
PIA Variable Annuity Account I was established as a separate account of the
Company on July 13, 1994. The Separate Account is registered with the
Securities and Exchange Commission as a unit investment trust under the
Investment Company Act of 1940.
  The Separate Account is divided into subaccounts for investment in shares of
different mutual funds. Income, gains and losses, realized or unrealized, of a
subaccount are credited to or charged against the subaccount without regard to
any other income, gains or losses of the Company. Assets equal to the reserves
and other contract liabilities with respect to each subaccount are not charge-
able with liabilities arising out of any other business of the Company. The
Company is obligated to pay all benefits and make all payments provided under
the Contracts.
  Amounts allocated or transferred to the Separate Account under the Contracts
are invested, at the direction of the Contract Owner, in one or more funds of
Penn Series Funds, Inc., American Century Variable Portfolios, Inc., Neuberger
& Berman Advisers Management Trust, Fidelity Investments' Variable Insurance
Products Fund, Fidelity Investments' Variable Insurance Products Fund II and
Morgan Stanley Universal Funds, Inc.
  The mutual funds have shareholders other than the Separate Account. Shares of
Penn Series Funds, Inc. are also sold to Penn Mutual and other separate ac-
counts of Penn Mutual that fund benefits under variable annuity and variable
life insurance contracts. Shares of American Century Variable Portfolios, Inc.,
Neuberger & Berman Advisers Management Trust, Fidelity Investments' Variable
Insurance Products Fund, Fidelity Investments' Variable Insurance Products Fund
II and Morgan Stanley Universal Funds, Inc. are sold to variable annuity and
variable life separate accounts of Penn Mutual, such accounts of other insur-
ance companies and, in the case of Neuberger & Berman Advisers Management
Trust, directly to qualified pension and retirement plans. Each mutual fund
will monitor events to identify any material conflicts that might arise between
the Separate Account and its other shareholders. See the accompanying prospec-
tuses of the funds for information on their monitoring for conflicts.

VOTING RIGHTS
 
  Under the Investment Company Act of 1940 as currently interpreted, Contract
Owners have the right to instruct the Company as to the voting of the shares of
the mutual funds held in the subaccounts of the Separate Account pursuant to
the Contracts. The number of shares of a fund for which voting instructions may
be given prior to the Contract Annuity Date is determined by dividing the
Contract Owner's interest in the applicable subaccount of the Separate Account
by the net asset value per share of the fund. The number of shares of a fund
for which voting instructions may be given after the Contract Annuity Date is
determined by dividing the reserve allocated to the applicable subaccount by
the net asset value per share of the fund. Should the applicable law, or
interpretations thereof, change so as to permit us to vote shares of the mutual
funds in our own right, we may elect to do so. Further, we reserve the right to
modify the manner in which we calculate the weight to be given to pass-through
voting instructions where such a change is necessary to comply with federal law
or interpretations thereof.
- --------------------------------------------------------------------------------
THE CONTRACT
 
  The Contract described in this prospectus is a combination variable and fixed
annuity contract. The Contract provides for investment, through subaccounts of
the Separate Account, in one or more of the available funds of Penn Series
Funds, Inc., American Century Variable Portfolios, Inc., Neuberger & Berman Ad-
visers Management Trust, Fidelity Investments' Variable Insurance Products
Fund, Fidelity Investments' Variable Insurance Products Fund II and Morgan
Stanley Universal Funds, Inc. It also provides for investment in one or more
fixed interest accounts. The fixed interest accounts are guaranteed and funded
by the Company through its general account. See THE FIXED INTEREST OPTIONS in
this prospectus.
  As the Contract Owner, you determine, within Contract limits (1) the amount
and frequency of the purchase payments to be made to the Company, (2) the in-
vestment options to which the purchase payments are to be allocated, (3) trans-
fers among investment options, (4) the form of annuity to be paid after the ac-
cumulation period and the person to whom it is to be paid, (5) the beneficiary
to whom death benefits are to be paid, and (6) the amount and frequency of
withdrawals from the Contract Value. Currently, for Contracts sold in Oregon,
New Jersey and Washington, purchase payments may be made only during the first
three contract years.
  During the variable annuity payout period, you (or the beneficiary in the
event of your death or the Annuitant's death) may transfer Annuity Unit values
among subaccounts of the Separate Account.
  Upon the earlier of the death of the Contract Owner (other than a trustee) or
Annuitant prior to the Annuity Date, the beneficiary may elect to receive a
death benefit in a lump sum or in the form of an annuity. A spousal beneficiary
may elect to become the Owner of the Contract.
  The Contract may be amended at any time to conform to applicable laws or gov-
ernmental regulations. If, in our judgment, investment in any of the mutual
funds becomes inappropriate to the purposes of the Contract, we may, with ap-
proval of the Securities and Exchange Commission and the governing state insur-
ance department, substitute another fund for existing and future investments.

- --------------------------------------------------------------------------------
PURCHASES
 
  To purchase a Contract, your completed application, together with a check for
the first purchase payment, should be forwarded to our administrative office.
Normally, a completed application form received at our administrative office
will be accepted within two business days. If an incomplete application is not
completed and acted upon within five business days, the purchase payment will
be returned to you unless you request that we retain it while you complete the
application. All subsequent purchase payments are sent directly to our adminis-
trative office.
  The minimum initial purchase payment is $5,000 for all non-qualified
contracts and $2,000 for individual retirement annuities under Section 408 of
the Internal Revenue Code and for tax deferred annuities under Section 403(b)
of the Code. For all Contracts, the minimum subsequent purchase payment that
will be accepted is $250. We may, in our discretion, reduce the minimum
requirements for initial and subsequent purchase payments. We will accept total
purchase payments under your Contract of up to $1 million. Total purchase
payments in excess of $1 million require our prior approval.
  Purchase payments allocated to the Separate Account are credited in the form
of Accumulation Units of the subaccount selected. The number of Accumulation
Units credited is determined by dividing the purchase payment allocated to the
Separate Account by the value of the Accumulation Unit at the end of the valua-
tion period in which the purchase payment is received at our administrative of-
fice or, in a case of the first purchase payment, is accepted by us.
  The principal underwriter of the Contract (under federal securities laws) is
Hornor, Townsend & Kent, Inc., 600 Dresher Road, Horsham, PA 19044, a wholly-
owned subsidiary of Penn Mutual.
- --------------------------------------------------------------------------------
ACCUMULATION UNITS
 
  For each subaccount of the Separate Account the value of an Accumulation Unit
will be $10 when the subaccount commences operation. The value of an
Accumulation Unit may increase or decrease from one valuation period to the
next.
  The value of an Accumulation Unit for a valuation period is determined by
multiplying the value of an Accumulation Unit for the prior valuation period by
the net investment factor for the subaccount for the current valuation period.
  The net investment factor is a measure of (1) investment performance of mu-
tual fund shares held in the subaccount, (2) any taxes on income or gains from
investments held in the subaccount and (3) the mortality and expense risk
charge at an annual rate of 1.25% and contract administration charge at an an-
nual rate of 0.15% assessed against the subaccount. Under current law, no taxes
are levied against income or gain from investments held in a subaccount.

  You may choose one of the following forms of annuity: (1) an annuity for a
specified number of years, (2) a life annuity, (3) a life annuity with payments
guaranteed for 10 or 20 years, (4) a joint and survivor life annuity or (5)
such other form of annuity as we may agree upon. You may select any one of
these forms of annuity as a variable annuity (except for a specified number of
years), a fixed annuity, or a combination of both.
  The level of the variable annuity payments is determined by various factors,
including the amount accumulated and applied under the Contract to the variable
annuity, the form of annuity chosen, the expected duration of the annuity
period, the performance of the applicable investment options, and the annuity
purchase rates and charges specified in the Contract.
  The variable annuity purchase rates assume an annual net investment return of
3%. If the annual net investment return during the annuity payout period is
greater than 3%, the level of the annuity payment increases. If the annual net
investment return is less than 3%, the level of the annuity payments decreases.
  The level of fixed annuity payments under a Contract is determined by various
factors, including the amount accumulated and applied under the Contract to the
fixed annuity, the form of annuity chosen, the expected duration of the annuity
period, and current annuity purchase rates for single premium nonparticipating
fixed annuity contracts issued by the Company.
  Unless you specify otherwise, you or such other person you designate will re-
ceive a life annuity with payments guaranteed for 10 years, except for tax de-
ferred annuities under Section 403(b) of the Code and pension or profit sharing
plans under Section 401 of the Code. Annuitants under those Contracts will re-
ceive a joint and survivor annuity. Unless you specify otherwise, the annuity
will be split between fixed and variable in the same proportions as the Con-
tract Value on the Annuity Date.
 
                                       13
<PAGE>
 
  Unless you specify otherwise, the Annuity Date will be the later of (1) the
first day of the next month after the Annuitant's 85th birthday or (2) 10 years
after the contract date, unless state law requires an earlier Annuity Date. The
Annuity Date under the Contract may not be earlier than the second contract an-
niversary and must be on the first day of a month.
  You may change the Annuity Date or annuity option by giving written notice at
our administrative office at least 30 days prior to the current Annuity Date.
If the Contract Value of a Contract is less than $5,000, we may elect to pay
such amount in a lump sum in place of an annuity. Annuity payments are gener-
ally monthly, starting with the Annuity Date, but may also be made quarterly,
semiannually or annually at your request. However, if any payment would be less
than $50, we may change the frequency of annuity payments so that payments are
at least $50 each.
- --------------------------------------------------------------------------------
DEATH BENEFIT
 
  If the Contract Owner or the Annuitant dies prior to the Annuity Date, we
will pay the beneficiary the greater of (1) the Contract Value for the valua-
tion period in which proof of death and any other required information needed
to make payment is received at our administrative office; or (2) the sum of the
Fixed Account Value on the date the above information is received at our admin-
istrative office and the net purchase payments and transfers allocated to the
Separate Account (i.e., all purchase payments and transfers to the Separate Ac-
count minus all prior withdrawals and transfers made from the Separate Ac-
count). The death benefit generally will be paid within 7 days after the Com-
pany has sufficient information to make the payment. For a discussion of the
tax treatment of a death benefit, see FEDERAL INCOME TAX CONSIDERATIONS in this
prospectus.
  If the Contract Owner dies before the age of 80 and if permitted by state
law, an enhanced death benefit will be paid to the beneficiary, if it is
greater than the Contract Value as of the receipt of proof of death and the
necessary information to make a death benefit payment. The enhanced death bene-
fit is the sum of: (1) the Fixed Account Value, and (2) the net purchase pay-
ments allocated to the Separate Account (as defined in the previous paragraph)
plus interest accumulated at an annual interest rate of 5% through the Contract
Owner's attained age 69, and interest accumulated at an annual interest rate of
3% for years subsequent to attained age 70.
  If the beneficiary is the Contract Owner's surviving spouse, the surviving
spouse has the right to become the Contract Owner rather than receive the death
benefit.
  Within one year of the date of death, the beneficiary may elect to receive
the death benefit in single sum or in the form of an annuity. If payment is to
be received in a single sum, it must be paid within five years of the date of
death (until paid out, the death benefit will be allocated to subaccounts of
the Separate Account and/or fixed interest options as directed by the benefi-
ciary). If an annuity is selected, payments must commence within one year of
the date of death and must be made over the beneficiary's life or over a period
not longer than the beneficiary's life expectancy. If an election is not made
within one year of the date of death, the death benefit will be paid to the
beneficiary in a single sum.
  If the Annuitant dies on or after the Annuity Date and the annuity is for a
specified number of years or for life with payments guaranteed for 10 or 20
years, the beneficiary may elect to have the payments continue for the speci-
fied or guaranteed period or to receive in lump sum the present value of the
remaining payments.
  You may designate a beneficiary in your application. You may change the bene-
ficiary at any time before your death or the death of the Annuitant, whichever
occurs first.
- --------------------------------------------------------------------------------
TRANSFERS
 
  Prior to the Annuity Date, you may transfer amounts from one subaccount of
the Separate Account to another subaccount of the Separate Account. Within cer-
tain additional limitations stated in the Contract, you may also transfer
amounts from the subaccounts of the Separate Account to a fixed interest option
of the Fixed Account prior to the Annuity Date. Transfers may be made from the
Fixed Account to the Variable Account or to another fixed interest option
within the Fixed Account only at the completion of the interest period or
within the 25 days thereafter.
  After the Annuity Date and during an annuity payout period, you may transfer
amounts (upon which the annuity payments are based) from one subaccount of the
Separate Account to another. Upon your death or the death of the Annuitant, a
beneficiary who is receiving annuity payments may transfer amounts among the
subaccounts of the Separate Account.
  The minimum amount that may be transferred is $250 or, if less, the amount
held in the subaccount or fixed interest option. In the case of partial trans-
fers, the amount remaining in the subaccount or fixed interest option must be
at least $250.
 
                                       14
<PAGE>
 
  A written request for transfer (or, if authorized in writing, a telephone
request for transfer) must be received at our administrative office and all
other administrative requirements for transfer must be met to make the
transfer. The Separate Account and the Company will not be liable for following
transfer instructions communicated by telephone that we reasonably believe to
be genuine. We require certain personal identifying information to process a
telephone transfer.
  DOLLAR COST AVERAGING: If you have a Contract Value of at least $10,000, you
may elect to have flat dollar amounts ($100 minimum) transferred monthly or
quarterly from one source account to other accounts ($50 minimum per account).
These transfers may be made only from one of the following accounts: Money Mar-
ket Subaccount, Limited Maturity Bond Subaccount, Quality Bond Subaccount, or
One Year Fixed Interest Option. The dollar cost averaging term may run from 12
to 60 months, or until you give notice of a change in allocation or cancella-
tion of the feature.
  AUTOMATIC REBALANCING: You may elect to have your investments in subaccounts
of the Separate Account automatically rebalanced. We will transfer funds under
your Contract on a quarterly (calendar) basis among the subaccounts to maintain
a specified percentage allocation among your selected variable investment op-
tions. Dollar cost averaging and automatic rebalancing may not be in effect at
the same time.
- --------------------------------------------------------------------------------
WITHDRAWALS
 
  Prior to the Annuity Date and prior to the earlier of the death of the Con-
tract Owner and Annuitant, you may withdraw all or part of your Contract Value.
Withdrawals will be based on values at the end of the valuation period in which
a proper written request for withdrawal (and the Contract, in case of a full
withdrawal) is received at our administrative office. Payment will normally be
made within seven days of receipt of the written request and the Contract, if
required. A withdrawal may result in certain tax consequences, including an ad-
ditional 10% tax under certain circumstances. For a discussion of the tax
treatment of withdrawals, see FEDERAL INCOME TAX CONSIDERATIONS in this pro-
spectus.
  The minimum withdrawal is $500 or, at the time of the first withdrawal in
each Contract Year, 15% of total purchase payments if less. A partial with-
drawal may be made from a subaccount of the Separate Account only if the amount
remaining in the subaccount is at least $250. If you request a partial with-
drawal without specifying allocation of the withdrawal among investment op-
tions, it will be taken pro rata from the variable subaccounts; if the partial
withdrawal exhausts your Variable Account Value, then any remaining withdrawal
will be taken from the fixed interest options beginning with the One Year Fixed
Interest Option and continuing with the other fixed interest options in order
of ascending duration.
  SYSTEMATIC WITHDRAWALS: You may make a request for a systematic withdrawal if
there is no previous withdrawal in the current contract year. The maximum value
of a systematic withdrawal request is 15% of total purchase payments at the
time of the request. A level systematic withdrawal will begin one modal period
after the date of receipt of the request. The systematic withdrawals may be
made on a monthly, quarterly, semiannual or annual basis. The minimum Contract
Value that is eligible for a systematic withdrawal is $25,000, and the minimum
amount of each withdrawal payment is $50. Payments can be made of either a
fixed dollar amount or of a fixed percentage of purchase payments. The latter
option provides a convenient way to take advantage of the ability to withdraw a
limited percentage of purchase payments without incurring a contingent deferred
sales charge. See FREE WITHDRAWALS below. For a discussion of the tax treatment
of withdrawals, see FEDERAL INCOME TAX CONSIDERATIONS in this prospectus.
  403(B) WITHDRAWALS: With respect to Contracts qualifying under Section 403(b)
of the Internal Revenue Code, there are certain restrictions on withdrawals.
Withdrawals may be made only if the Contract Owner is over the age of 59 1/2,
leaves the employment of the employer, dies, or becomes disabled as defined in
the Code. Withdrawals (other than withdrawals attributable to income earned on
purchase payments) may also be possible in the case of hardship as defined in
the Code. The restrictions do not apply to transfers among subaccounts and may
also not apply to transfers to other investments qualifying under Section
403(b). For a discussion of the tax treatment of withdrawals under Section
403(b) Contracts, see FEDERAL INCOME TAX CONSIDERATIONS in this prospectus.
- --------------------------------------------------------------------------------
DEFERMENT OF PAYMENTS AND TRANSFERS
 
  We reserve the right to defer a withdrawal, a transfer of values or annuity
payments funded by the Separate Account if (a) the New York Stock Exchange is
closed (other than customary weekend and holiday closings); (b) trading on the
Exchange is restricted; (c) an emergency exists such that it is not reasonably
practical to dispose of securities held in the Separate Account or to determine
the value of its assets; or (d) the Securities and Exchange Commission by order
so permits for the protection of investors. Conditions described in (b) and (c)
will be decided by, or in accordance with rules of, the Commission.

CHARGES
 
  ADMINISTRATION CHARGES: Charges are assessed to reimburse us for the expenses
we incur in administering the Contract and the Separate Account. First, on each
Contract Anniversary prior to the Annuity Date (and any other date the Variable
Account Value is reduced to zero through withdrawal or transfer), we deduct
from the Variable Account Value a contract administration charge of $30 or, if
less, 2% of the Variable Account Value. We will not, however, deduct this
charge if the Variable Account Value is greater than $50,000. The charge is
made by canceling Accumulation Units credited to the Contract, with the charge
allocated pro rata among the subaccounts comprising the Variable Account Value.
Second, we deduct from the Separate Account a daily administration charge equal
to an effective annual rate of 0.15% of the daily net asset value of the
Separate Account. These administration charges are guaranteed not to increase
and are intended to cover our average anticipated administration expenses over
the periods the Contracts are in force.
  MORTALITY AND EXPENSE RISK CHARGE: We deduct a daily mortality and expense
risk charge equal to an effective annual rate of 1.25% of the daily net asset
value of the Separate Account. This charge is to compensate us for the mortali-
ty-related guarantees we make under the Contract (e.g., the death benefit and
the guarantee that the annuity factors will never be decreased even if mortal-
ity experience is substantially different than originally assumed), and for the
risk that our administration charges will be insufficient to cover administra-
tion expenses over the life of the Contracts. The mortality and expense risk
charge is assessed during both the accumulation and variable annuity pay-out
phases of the Contract.
  CONTINGENT DEFERRED SALES CHARGE: A contingent deferred sales charge may be
deducted in the event of full or partial withdrawal from the Contract Value
prior to the Annuity Date. This charge is made to cover sales expenses that we
have incurred. Sales expenses which are not covered by the deferred sales
charge are paid from the surplus of the Company, which may include proceeds
from the mortality and expense risk charge.
  A contingent deferred sales charge, if applicable, will be imposed only on a
withdrawal of a purchase payment in cases where the purchase payment was made
within seven years of the date of the withdrawal. The following table shows the
schedule of the contingent deferred sales charge that will be applied to with-
drawal of a purchase payment, after allowing for the free withdrawals which are
described in the next subsection. Purchase payments will be treated as with-
drawn on a first-in, first-out basis.

</TABLE>
  The contingent deferred sales charge may be reduced on Contracts sold to a
trustee, employer or similar party pursuant to a retirement plan or to a group
of individuals, if such sales are expected to involve reduced sales expenses.
The amount of reduction will depend upon such factors as the size of the group,
any prior or existing relationship with the purchaser or group, the total
amount of purchase payments and other relevant factors that might tend to re-
duce expenses incurred in connection with such sales. The reduction will not be
unfairly discriminatory to any Contract Owner.
 
  FREE WITHDRAWALS:
 
  Seven-Year-Old Purchase Payments. You may withdraw any purchase payment which
  ---------------------------------
was made more than 7 years before the withdrawal without incurring a contingent
deferred sales charge.
  15% Withdrawals. On the last day of the first contract year and once each
  ----------------
contract year thereafter, you may withdraw, without incurring a contingent de-
ferred sales charge, 15% of total purchase payments. You may take the 15% free
withdrawal on a single sum basis or systematically, but not both. The 15% free
withdrawal amount will be applied to purchase payments on a first-in, first-out
basis. With respect to any withdrawal in excess of the 15% free withdrawal in a
contract year, the contingent deferred sales charge schedule set forth above
will apply to the remainder of the purchase payments so withdrawn
 
                                       16
<PAGE>
 
on a first-in, first-out basis. This 15% free withdrawal applies only to the
first withdrawal request made in a contract year (after the first contract
year) and the amount is not cumulative from year to year.
  Medically Related Withdrawal. Subject to applicable state law, after the
  -----------------------------
first contract year and before the Annuity Date, you may withdraw, without in-
curring a contingent deferred sales charge, up to the lesser of $500,000 or
your Contract Value if certain medically related contingencies occur. This free
withdrawal is available if you are (1) first confined in a nursing home or hos-
pital while this Contract is in force and remain confined for at least 90 days
in a row or (2) first diagnosed as having a fatal illness (an illness expected
to result in death within 2 years for 80% of diagnosed cases) while this Con-
tract is in force. The precise terms and conditions of this benefit are set
forth in the Contract. It is not available if your age at issue is greater than
75. The medically related contingencies that must be met for free withdrawal
vary in some states.
  Disability Related Withdrawal. You may withdraw, without incurring a contin-
  ------------------------------
gent deferred sales charge, part or all of your Contract Value if you (you or
the Annuitant for qualified Contracts) become totally disabled as defined in
the Contract.
  Other Withdrawals. There is no contingent deferred sales charge imposed upon
  ------------------
minimum distributions under qualified contracts which are required by the In-
ternal Revenue Code.
 
  PREMIUM TAXES:
 
  Some states and municipalities impose premium taxes on purchase payments re-
ceived by insurance companies. Generally, any premium taxes payable will be de-
ducted upon annuitization, although we reserve the right to deduct such taxes
when due in jurisdictions that impose such taxes on purchase payments. Current-
ly, state premium taxes on purchase payments range from 0% to 3 1/2%.
- --------------------------------------------------------------------------------
PERFORMANCE INFORMATION
 
  The Company may advertise total return performance and annual changes in ac-
cumulation unit values. We may also provide information on "yields" and "effec-
tive yields" on investments in the Money Market Fund subaccount.
  Information on total return performance will include average annual rates of
total return for one, five and ten year periods, or lesser periods depending on
how long the underlying fund portfolio has been in existence. Such figures are
based on the hypothetical assumption that the Separate Account invested in the
underlying portfolios from the date those portfolios were first available to
other insurance company separate accounts. Average annual total return figures
will show the average annual rates of increase or decrease in investments in
the subaccounts, assuming a hypothetical $1,000 investment at the beginning of
the period, withdrawal of the investment at the end of the period, and the de-
duction of all applicable fund and Contract charges. We may also show average
annual rates of total return, assuming other amounts invested at the beginning
of the period and no withdrawal at the end of the period. Average annual total
return figures which assume no withdrawals at the end of the period will re-
flect all recurring charges, but will not reflect the contingent deferred sales
charge (if applicable, the contingent deferred sales charge would reduce the
amount that may be withdrawn under the Contracts).
  The "yield" on an investment in the Money Market Fund subaccount refers to
the income generated by the investment over a 7-day period. This income is then
annualized. That is, the amount of income generated by the investment during
that week is assumed to be generated each week over a 52-week period and is
shown as a percentage of the investment. The "effective yield" is calculated
similarly, but, when annualized, the income earned by an investment in the
subaccount is assumed to be reinvested. The effective yield will be slightly
higher than the yield because of the compounding effect of this assumed rein-
vestment.

- --------------------------------------------------------------------------------
GENERAL INFORMATION
 
  Subject to the laws of your state, you may allocate or transfer all or part
of the amount credited to your Contract to one or more of the following fixed
interest options in the Fixed Account: (1) the One Year Fixed Interest Option;
(2) the Three Year Fixed Interest Option; (3) the Five Year Fixed Interest Op-
tion; and (4) the Seven Year Fixed Interest Option. We periodically declare an
effective annual interest rate applicable to allocations to the various fixed
interest options. For each amount allocated to the One Year Fixed Interest Op-
tion, the Three Year Fixed Interest Option, the Five Year Fixed Interest Option
or the Seven Year Fixed Interest Option, we credit interest at an effective an-
nual interest rate declared by us in the month in which the allocation is made.
The declared rate of interest will apply through the end of the 12-month, 36-
month, 60-month or 84-month period, as applicable, which begins on the first
day of the calendar month in which the allocation is made. We guarantee an ef-
fective annual rate of interest on allocations to all fixed interest options of
not less than 3%. In addition, we guarantee that the rate credited in the One
Year Fixed Interest Option will at least equal the increase in the cost of liv-
ing as calculated by the Company; the Company uses for this purpose a six-month
average of the relative change by month in the Consumer Price Index published
by the Bureau of Labor Statistics.
  You may transfer amounts in the Fixed Account to subaccounts of the Separate
Account or to another fixed interest option within the Fixed Account, subject
to the conditions and limitations in the fixed account provisions of your
Contract. A premature withdrawal charge in an amount specified in the Contract
will be deducted from the interest earned on any amount that is withdrawn from
the Three Year Fixed Interest Option, the Five Year Fixed Interest Option or
the Seven Year Fixed Interest Option prior to the expiration of the period for
which the interest rate is guaranteed. Amounts not withdrawn or reallocated
within 25 days after the end of an interest period are rolled over and treated
as a new allocation to the same fixed interest option. The premature withdrawal
charge is not applicable to amounts withdrawn to effect an annuity or to meet
the minimum distribution requirement under the tax laws. Nor will the premature
withdrawal charge be applied to amounts withdrawn due to the death, total
disability, or defined medical confinement or terminal illness of the owner or
annuitant, as specified in the Contract. In no event will the premature
withdrawal charge be greater than the total amount of interest credited to the
applicable fixed interest option. In accordance with state law, we may defer a
withdrawal or transfer from the Fixed Account for up to six months if we
reasonably determine that investment conditions are such that an orderly sale
of assets in the Company's general account is not feasible.
- --------------------------------------------------------------------------------
LOANS UNDER SECTION 403(B) CONTRACTS
 
  Subject to compliance with applicable state law, Contract Owners qualifying
under Section 403(b) of the Code may be able to borrow against a portion of the
amount credited under their Contract, provided the loan privilege has been ap-
proved in the applicable state. The loan will be made from the general account
of the Company. Because this prospectus generally is limited to describing the
variable portion of the Contract, you should review the Contract loan endorse-
ment or consult your Company representative for a complete description of the
terms of the loan privilege, including minimum and maximum loan amounts, repay-
ment terms, and restrictions on prepayments. The following paragraphs describe
how exercise of the loan privilege may relate to the Variable Account Value.
  First, at the time a Contract loan is made and in accordance with your
direction, an amount equal to the initial loan amount will be transferred from
the Contract's investment options to an account in the Company's general
account called the "Restricted Account." Amounts transferred from investment
options to the Restricted Account will not participate in the investment
experience of those investment options. Amounts transferred to the Restricted
Account will generally earn interest at a rate 2 1/2 percentage points less
than the rate of interest charged on the loan.
  Second, on your Contract Anniversary, the accrued interest in the Restricted
Account will be transferred to your investment options in accordance with your
current payment allocation instructions.
  Third, loan repayments, which are due quarterly, will result in the transfer
of an amount equal to the principal portion of the repayment from the Re-
stricted Account to the Money Market subaccount. You may then transfer amounts
from the Money Market subaccount to the other investment options offered under
the Contract.
  Fourth, if a payment or the entire loan is in default as defined in the
Contract, the Company will report the amount of the default to the Internal
Revenue Service as a taxable distribution and, if you are then under age 59
1/2, as a premature distribution. Subject to restrictions in Section 403(b) of
the Code, the amount of any missed payment, plus interest, or the entire loan
balance, plus interest, if the entire loan is in default, plus any applicable
contingent deferred sales charge, will be withdrawn by us from your investment
options in accordance with your direction in the Loan Request and Agreement. We
will use the net proceeds from the withdrawal to repay the loan. If a
withdrawal is restricted under the Code, the outstanding loan
 
                                       18
<PAGE>
 
balance will continue to accrue interest and the amount due will be withdrawn
when a withdrawal becomes permissible. Thus, when an event takes place which
makes withdrawal from the Contract permissible under the Code, such as
attainment of age 59 1/2, disability, or death, we will check the Contract to
determine if there is an outstanding loan balance for which one or more
payments have been missed. If so, we will withdraw from your investment
options, in accordance with your direction in the Loan Request and Agreement,
funds necessary to pay the overdue amount, plus any applicable contingent
deferred sales charge. While a loan balance is outstanding, any withdrawal or
death benefit proceeds must first be used to pay the loan.
 
  Loans are subject to the terms of your Contract, your Section 403(b) plan and
the Code, and, in the case of plans subject to the Employee Retirement Income
Security Act of 1974, the ERISA regulations on plan loans, all of which may
impose restrictions. The Company reserves the right to suspend, modify or
terminate the availability of loans. Where there is a plan fiduciary, it is the
responsibility of the fiduciary to ensure that any Contract loans comply with
plan qualification requirements, including ERISA.
- --------------------------------------------------------------------------------
FEDERAL INCOME TAX CONSIDERATIONS
 
The following brief discussion of federal income tax considerations is based on
the law in effect on the date of this prospectus, which may be changed by
legislative, judicial or administration action. The summary is general in
nature and does not consider any applicable state or local tax laws. For
further information, you should consult qualified tax counsel.
  Under current law, no federal income taxes are imposed on increases in the
value of a Contract until distribution occurs, either in the form of a with-
drawal or death benefit or as annuity payment under an annuity option.
  For a withdrawal or death benefit, the taxable portion is generally the
amount in excess of the cost basis of the Contract. Amounts withdrawn by the
Contract owner or received as a death benefit by the designated beneficiary are
treated first as taxable income to the extent of the excess of the Contract
Value over the purchase payments made under the Contract. Such taxable portion
is taxed at ordinary income tax rates. Designation of a beneficiary who is ei-
ther 37 1/2 years younger than the Contract Owner or a grandchild of the Con-
tract Owner may have Generation Skipping Transfer Tax consequences under Sec-
tion 2601 of the Internal Revenue Code.
  For annuity payments, the taxable portion is generally determined by a for-
mula that establishes the ratio of the cost basis of the Contract (as adjusted
for any refund feature) to the expected return under the Contract. The taxable
portion, which is the amount of the annuity payment in excess of the cost ba-
sis, is taxed at ordinary income tax rates.
  An additional income tax of 10% may be imposed on the taxable portion of an
early withdrawal or distribution unless one of several exceptions apply. There
will be no additional income tax on early withdrawals which are part of a
series of substantially equal periodic payments (not less frequently than
annually) made for life (or life expectancy) of the taxpayer or the joint lives
(or joint life expectancies) of the taxpayer and a beneficiary, or on
withdrawals made on or after age 59 1/2. There also will be no additional tax
on distributions made after death or on withdrawals attributable to total and
permanent disability. Further, there will be no additional tax on distributions
within certain other exceptions to the general rule.
  The transfer of a Contract may result in the transferor incurring tax. If the
transfer is for less than adequate consideration the taxable portion would be
the Contract Value at the time of transfer over the investment in the Contract
at such time. This rule does not apply to transfers between spouses or to
transfers incident to a divorce.
  Subject to certain exceptions, a Contract must be held by or on behalf of a
natural person in order to be treated as an annuity contract under federal in-
come tax law and to be accorded the tax treatment described in the preceding
paragraphs. If a contract is not treated as an annuity contract for federal in-
come tax purposes, the income on the Contract is treated as ordinary income re-
ceived or accrued by the Contract Owner during the taxable year.
  Section 817(h) of the Code provides that the investments of a separate ac-
count underlying a variable annuity contract which is not purchased under a
qualified retirement plan or certain other types of plans (or the investments
of a mutual fund, the shares of which are owned by the variable annuity sepa-
rate account) must be "adequately diversified" in order for the Contract to be
treated as an annuity contract for tax purposes. The Treasury Department has
issued regulations prescribing such diversification requirements. The Separate
Account, through each of the available funds of the Penn Series Funds, Inc.,
American Century Variable Portfolios, Inc., Neuberger & Berman Advisers Manage-
ment Trust, Variable Insurance Products Fund, Variable Insurance Products
Fund II, and Morgan Stanley Universal Funds, Inc. intends to comply with those
requirements. The requirements are briefly discussed in the accompanying pro-
spectuses for the underlying funds.
  The Treasury Department has indicated that in regulations or revenue rulings
under Section 817(d) (relating to the definition of a variable contract), it
will provide guidance on the extent to which contract owners may direct their
investments to particular subaccounts without being treated as owners of the
underlying shares. It is possible that when such regulations or rulings are
issued, the Contracts may need to be modified to comply with them.

  The Contracts may be used in connection with retirement plans that qualify
for special tax treatment under the Code. The plans include individual retire-
ment annuities qualified under Section 408(b) of the Code (referred to as
IRAs), tax deferred annuities qualified under Section 403(b) of the Code, pen-
sion or profit sharing plans for self-employed individuals qualified under Sec-
tion 401 of the Code (referred to as H.R. 10 or Keogh plans) and corporate pen-
sion or profit sharing plans qualified under Section 401 of the Code, or annu-
ity plans qualified under Section 403(a) of the Code. Special provisions are
required in some Contracts for qualification under the Code.
  For some types of qualified retirement plans, there may be no cost basis in
the Contract. In this case, the total payments received may be taxable. Before
purchasing a contract under a qualified retirement plan, the tax law provisions
applicable to the particular plan should be considered.
  Generally, under a nonqualified annuity or individual retirement annuity
qualified under Section 408(b), unless the Contract Owner elects to the
contrary, any amounts that are received under the Contract that the Company
believes are includable in gross income for tax purposes will be subject to
withholding to meet federal income tax obligations. The same treatment will
apply to distributions from a qualified plan or Section 403(b) annuity that are
payable as an annuity for the life or life expectancy of one or more
individuals, or for a period of at least 10 years, or are required minimum
distributions. Other distributions from a qualified plan or a Section 403(b)
annuity are subject to mandatory withholding, unless an election is made to
receive the distribution as a direct rollover to another eligible retirement
plan.

VARIABLE ANNUITY PAYMENTS
 
- -------------------------------------------------------------------------------
FIRST VARIABLE ANNUITY PAYMENT
 
  When a variable annuity is effected, we will first deduct applicable premium
taxes, if any, from the Contract Value. The dollar amount of the first monthly
annuity payment will be determined by applying the net Contract Value to the
annuity table set forth in the contract for the annuity option chosen. The
annuity tables show the amount of the first monthly income payment under each
annuity option for each $1,000 of value applied, based on the Annuitant's age
at the Annuity Date. The annuity tables are based on the 1983 Individual
Annuity Mortality Tables with interest at 3%.
 
- -------------------------------------------------------------------------------
SUBSEQUENT VARIABLE ANNUITY PAYMENTS
 
  The dollar amount of subsequent variable annuity payments will vary in
accordance with the investment experience of the subaccount(s) of the Separate
Account applicable to the annuity. Each subsequent variable annuity payment
will equal the number of annuity units credited, multiplied by the value of
the annuity unit for the valuation period. The Company guarantees that the
amount of each subsequent annuity payment will not be affected by variations
in expense or mortality experience.
 
- -------------------------------------------------------------------------------
ANNUITY UNITS
 
  For each subaccount selected, the number of annuity units is the amount of
the first annuity payment allocated to the subaccount divided by the value of
an annuity unit for the subaccount on the Annuity Date. The number of your
annuity units will not change as a result of investment experience.
 
- -------------------------------------------------------------------------------
VALUE OF ANNUITY UNITS
 
  The value of an annuity unit for each subaccount was arbitrarily set at $10
when the subaccount was established. The value may increase or decrease from
one valuation period to the next. For a valuation period, the value of an
annuity unit for a subaccount is the value of an annuity unit for the
subaccount for the last prior valuation period multiplied by the net
investment factor for the subaccount for the valuation period. The result is
then multiplied by a factor to neutralize an assumed interest rate of 3% built
into the annuity tables.
 
- -------------------------------------------------------------------------------
NET INVESTMENT FACTOR
 
  For any subaccount the net investment factor for a valuation period is
determined by dividing (a) by (b) and subtracting (c):
WHERE (A) IS:
  The net asset value per share of the mutual fund held in the subaccount, as
  of the end of the valuation period
  plus
  The per share amount of any dividend or capital gain distributions by the
  mutual fund if the "ex-dividend" date occurs in the valuation period
  plus or minus
  A per share charge or credit, as we may determine as of the end of the
  valuation period, for provision for taxes (if applicable).
WHERE (B) IS:
  The net asset value per share of the mutual fund held in the subaccount as
  of the end of the last prior valuation period
  plus or minus
  The per share charge or credit for provision for taxes as of the end of the
  last prior valuation period (if applicable).
WHERE (C) IS:
  The sum of the mortality and expense risk charge and the daily
  administration charge. On an annual basis, the sum of such charges equals
  1.40% of the daily net asset value of the subaccount.
 
                                      B-2
<PAGE>
 
- --------------------------------------------------------------------------------
ASSUMED INTEREST RATE
 
  A 3% assumed annual interest rate is included in the annuity tables in the
contracts. A higher assumption would mean a higher first annuity payment but
more slowly rising or more rapidly falling subsequent payments. A lower
assumption would have the opposite effect. If the actual net investment rate is
3% on an annual basis, annuity payments will be level.
 
- --------------------------------------------------------------------------------
VALUATION PERIOD
 
  Valuation period is the period from one valuation of underlying fund assets
to the next. Valuation is performed each day the New York Stock Exchange is
open for trading.

  The average annual rates of total return shown in Table 1 are computed by
finding the average annual compounded rates of return over the periods shown
that would equate the initial amount invested to the withdrawal value, in
accordance with the following formula: P(1 + T)n = ERV. In the formula, P is a
hypothetical investment payment of $1,000; T is the average annual total
return; n is the number of years; and ERV is the withdrawal value at the end of
the periods shown. The $30 annual contract administration charge is reflected
assuming an anticipated average Contract Value and assuming that the Contract
Value is allocated equally across all available subaccounts by an average
contract owner.

  The average annual rates of total return shown in Tables 2 and 3 are computed
by finding the average annual compounded rates of return over the periods shown
that would equate the initial amount invested to the Contract Value at the end
of the periods shown, in accordance with the following formula: P(1 + T)n = FV.
In the formula, P is a hypothetical investment of $1,000 in Table 2 and $10,000
in Table 3; T is the average annual total return; n is the number of years; and
FV is the Contract Value at the end of the periods shown. The $30 annual
contract administrative charge is reflected assuming an anticipated average
Contract Value and assuming that the average Contract Value is allocated
equally across all available subaccounts by an average contract owner. The
average annual rates of total returns reflect all recurring charges, but do not
reflect the contingent deferred sales charge ranging from 6% to 1% which, if
applicable, would reduce the amount that may be withdrawn under the Contract.

YIELDS (MONEY MARKET FUND)
 
  From time to time, advertisements and sales literature may quote the current
or effective yield of the Money Market subaccount.
  The "yield" and "effective yield" of the Money Market Fund subaccount for the
seven days ended December 31, 1996 were 2.98% and 3.02%, respectively.
  The yield is computed by determining the net change, exclusive of capital
changes, in the value of a hypothetical preexisting account having a balance of
one accumulation unit of the subaccount at the beginning of the period,
subtracting a hypothetical charge reflecting deductions from contract owner
accounts, and dividing the difference by the value of the account at the
beginning of the base period to obtain the base period return, and then
multiplying the base period return by (365/7) with
 
                                      B-7
<PAGE>
 
the resulting figure carried to at least the nearest hundredth of 1%. The
hypothetical charge reflects deductions from contract owners' accounts in
proportion to the length of the base period. The $30 annual contract
administrative charge is reflected assuming an anticipated average Contract
Value and assuming that the average Contract Value is allocated equally across
all available subaccounts by an average contract owner.
  The effective yield is obtained by taking the base period return as computed
above, and then compounding the base period return by adding 1, raising the sum
to a power equal to 365 divided by 7, and subtracting 1 from the result,
according to the following formula: Effective Yield = [(base period return +
1)/365/7/] -1.
  The yields do not reflect the contingent deferred sales charge ranging from
6% to 1%. The deferred sales charge may or may not be applicable to a
withdrawal from a Contract, depending on when the withdrawal is made.
  THE YIELDS ON AMOUNTS HELD IN THE MONEY MARKET SUBACCOUNT NORMALLY WILL
FLUCTUATE ON A DAILY BASIS. THEREFORE, THE STATED YIELDS FOR ANY GIVEN PERIOD
ARE NOT AN INDICATION OR REPRESENTATION OF FUTURE YIELDS.

REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE PENN INSURANCE AND ANNUITY COMPANY
AND CONTRACT OWNERS OF
PIA VARIABLE ANNUITY ACCOUNT I--PENNANT:
 
We have audited the accompanying statement of assets and liabilities of the PIA
Variable Annuity Account I -- Pennant [comprising, respectively, Money Market
Fund, Quality Bond Fund, High Yield Bond Fund, Growth Equity Fund, Value Equity
Fund, Flexibly Managed Fund, Small Capitalization Fund, International Equity
Fund, Balanced Portfolio, Limited Maturity Bond Portfolio, Capital Appreciation
Portfolio (formerly TCI Growth Portfolio) Equity Income Portfolio, Growth
Portfolio, and Asset Manager Portfolio] as of December 31, 1996, and the
related statement of operations for the year then ended, and the statements of
changes in net assets for the year then ended, and the period from March 1,
1995 (commencement of operations) to December 31, 1995. These financial
statements are the responsibility of the management of PIA Variable Annuity
Account I -- Pennant. 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 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. Our
procedures included confirmation of securities owned as of December 31, 1996 by
correspondence with the transfer agents. 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.
 
In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of PIA Variable Annuity Account I
- -- Pennant as of December 31, 1996, the results of its operations for the year
then ended and its changes in net assets for the year then ended, and the
period from March 1, 1995 (commencement of operations) to December 31, 1995 in
conformity with generally accepted accounting principles.

PIA VARIABLE ANNUITY ACCOUNT I - PENNANT
NOTES TO FINANCIAL STATEMENTS - DECEMBER 31, 1996
 
- --------------------------------------------------------------------------------
NOTE 3.
 
  Operations are charged for mortality and expense risks assumed by PIA and
  for administering the separate account at an annual rate of 1.25% and 0.15%
  respectively, of the average account value of Account I.
 
  As reimbursement for expenses incurred in administering the contract, PIA
  receives $30 per year for each annuity contract prior to the contract's
  anniversary date. The $30 charge is waived on certain contracts.
 
  If a policy is surrendered within the first 7 years, a contingent deferred
  sales charge will be assessed. This charge will be deducted before any
  surrender proceeds are paid. See original contract documents for specific
  charges assessed.

REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE BOARD OF DIRECTORS OF
THE PENN INSURANCE AND ANNUITY COMPANY
WILMINGTON, DELAWARE
 
We have audited the accompanying statutory statements of financial condition of
The Penn Insurance and Annuity Company (a wholly-owned subsidiary of The Penn
Mutual Life Insurance Company) as of December 31, 1996 and 1995 and the related
statutory statements of operations, changes in capital and surplus and cash
flows for the three years in the period ended December 31, 1996. These
statutory 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 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.
 
As described more fully in Note 1 to the financial statements, the Company
prepared these financial statements using accounting practices prescribed or
permitted by the Insurance Department of the State of Delaware (SAP), which
practices differ from generally accepted accounting principles (GAAP). The
effects on the financial statements of the variances between SAP and GAAP are
described in Note 1 to the financial statements.
 
In our report dated January 26, 1996, we expressed our opinion that the 1995
and 1994 financial statements, prepared using SAP, presented fairly, in all
material respects, the financial position of The Penn Insurance and Annuity
Company as of December 31, 1995, and the results of its operations, and its
cash flows for the two years then ended in conformity with GAAP. As described
in Note 1 to the financial statements, financial statements of wholly-owned
stock life insurance subsidiaries of mutual life insurance companies issued or
reissued after 1996, which are prepared in accordance with SAP, are no longer
considered to be presented in conformity with GAAP. Accordingly, our present
opinion on the 1995 and 1994 financial statements as presented herein is
different from that expressed in our previous report.
 
In our opinion, because of the effects of the matter discussed in the second
preceding paragraph, the financial statements referred to above do not present
fairly, in conformity with GAAP, the financial position of The Penn Insurance
and Annuity Company as of December 31, 1996 and 1995, or the results of its
operations or its cash flows for the three years in the period ended December
31, 1996.
 
In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial condition of The Penn Insurance and
Annuity Company as of December 31, 1996 and 1995, and the results of its
operations and its cash flows for the three years in the period ended December
31, 1996, on the basis of accounting described in Note 1.
 
As discussed in Note 2 to the financial statements, during 1995, the Company
changed its accounting method for certain components of the federal income tax
expense.

THE PENN INSURANCE AND ANNUITY COMPANY
NOTES TO FINANCIAL STATEMENTS
FOR THE YEARS ENDED DECEMBER 31, 1996 AND 1995
(IN THOUSANDS OF DOLLARS)
 
NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
NATURE OF OPERATIONS
 
The Penn Insurance and Annuity Company (the "Company"), is a wholly owned
subsidiary of The Penn Mutual Life Insurance Company ("Penn Mutual"). The
Company currently concentrates primarily in the sale of individual annuity
products, both fixed and variable. The Company sells its products through Penn
Mutual's distribution systems, which consist of a network of career agents,
independent agents and independent marketing organizations. Additionally, it
has a significant amount of universal life insurance business in force,
although the Company no longer sells these products. The Company is licensed
to do business in forty-seven states and the District of Columbia.
 
BASIS OF PRESENTATION
 
The financial statements of the Company have been prepared in conformity with
accounting principles prescribed or permitted by the Insurance Department of
the State of Delaware (SAP). Prescribed SAP include state laws, regulations,
and general administrative rules, as well as a variety of publications of the
National Association of Insurance Commissioners (NAIC). Permitted SAP
encompass all accounting practices which are not prescribed. These principles
were considered to be in conformity with generally accepted accounting
principles (GAAP) prior to the issuance of Financial Accounting Standards
Board Interpretation No. 40, "Applicability of Generally Accepted Accounting
Principles to Mutual Life Insurance and Other Enterprises," (FIN No. 40) and
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." Effective for fiscal years
beginning after December 15, 1995, in accordance with FIN No. 40, the
financial statements of mutual life insurance companies which are prepared on
the basis of SAP can no longer be described as prepared in conformity with
GAAP. Therefore, as required by generally accepted auditing standards, the
opinion expressed by our independent accountants on the 1995 and 1994
financial statements is different from that expressed in their previous
report.
 
In financial statements prepared in conformity with SAP, the accounting
treatment of certain items is different than for financial statements issued
in conformity with GAAP. Significant differences include:
 
  . Policy acquisition costs, such as commissions and other costs incurred in
    connection with acquiring new and renewal business, are expensed when in-
    curred; under GAAP, such costs are deferred and amortized over the ex-
    pected premium paying period.
 
  . Premiums for universal life and investment-type products are recognized
    as revenue when due; under GAAP, they are accounted for as deposits and
    excluded from revenue.
 
  . Policy reserves are based on statutory mortality and interest require-
    ments and without consideration of withdrawals and are reported net of
    reinsurance reserve credits; under GAAP, the reserves are based on ex-
    pected investment yield, mortality and withdrawals and are reported gross
    of reinsurance reserve credits. Changes in reserves on account of change
    in valuation basis during the year are charged directly to surplus rather
    than reflected in the net gain from operations, as is the case under
    GAAP.
 
  . No provision is made for deferred income taxes; under GAAP, deferred
    taxes result from temporary differences between the tax basis of assets
    and liabilities and their reported amounts in the financial statements.
 
  . An asset valuation reserve (AVR) is established as a liability to offset
    potential investment losses and changes in the AVR are charged or cred-
    ited to surplus; under GAAP, reserves are established for invested assets
    based on evaluation of impairment and are recorded through realized
    gains/(losses).
 
  . An interest maintenance reserve (IMR) is established as a liability to
    capture gains and losses, net of tax, on the sale of fixed maturities re-
    sulting from changes in the general level of interest rates; no such re-
    serve is required under GAAP.
 
  . Investments in bonds and preferred stocks are generally carried at amor-
    tized cost; under GAAP, investments in bonds and preferred stocks, other
    than those classified as held to maturity, are carried at fair value.
 
  . Certain assets, designated as nonadmitted, are excluded from assets by a
    direct charge to surplus; under GAAP, such assets are carried on the
    statement of financial condition with appropriate valuation allowances.

NOTES TO FINANCIAL STATEMENTS, CONTINUED
(IN THOUSANDS OF DOLLARS)
 
  . In accordance with Delaware Insurance Laws and Regulations, the Company's
    subsidiary is not consolidated for statutory filing purposes; under GAAP,
    majority-owned subsidiaries are consolidated.
 
The preparation of financial statements requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
the disclosure of contingent assets and liabilities at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period.
 
VALUATION OF INVESTMENTS
 
Bonds and stocks are carried in the accompanying statements of financial
condition at values prescribed by the NAIC. In general, bonds are stated at
amortized cost, preferred stocks at cost and common stocks at market value.
The Company's wholly-owned subsidiary, Penn Assurance and Reinsurance Co.,
Ltd. (PAR), is carried on the equity basis. Changes in PAR's equity are
charged or credited directly to capital and surplus. Real estate is carried at
cost less encumbrances and accumulated depreciation. Real estate acquired
through foreclosure is recorded at the lower of cost or market value at the
time of foreclosure. Real estate is depreciated using the straight-line
method. Mortgage loans are carried at the unpaid principal amount, less any
unamortized discount. Policy loans are carried at the unpaid principal balance
less amounts unsecured by cash surrender values. Cash and short-term
investments include cash on deposit and securities purchased with a maturity
date of less than one year. Short-term investments are valued at cost, which
approximates market. Certain assets which are considered to be non-admitted
for statutory purposes have been excluded from the Statements of Financial
Condition by a direct charge to capital and surplus.
 
Financial instruments utilized to hedge the Company's assets are recorded
using a valuation method consistent with the valuation method of the assets
hedged. Gains and losses on financial futures contracts used as hedges against
interest rate fluctuations are deferred and recognized in the Statements of
Operations over the remaining life of the hedged securities. Changes in the
market value of financial futures contracts used as hedges against market
fluctuations of equity securities are reported as unrealized gains or losses.
They are recognized as realized gains or losses when the hedged securities are
sold.
 
Statutory accounting principles require insurance companies to hold an Asset
Valuation Reserve (AVR) and an Interest Maintenance Reserve (IMR). The purpose
of the AVR is to maintain consistent and prescribed valuation reserves for
invested assets. Changes in the AVR are recorded directly to capital and
surplus. The purpose of the IMR is to defer recognition of realized gains and
losses which result from interest rate movements and to amortize these gains
and losses into income over the original expected life of the investment sold.
Amortization of gains and losses included in the IMR are reflected as a
component of net investment income.
 
Realized gains and losses are determined on the specific identification method
and are presented in the Statements of Operations net of taxes and excluding
net gains and losses transferred to the IMR. Unrealized gains and losses are
accounted for as direct increases or decreases in capital and surplus.
 
RESERVES AND FUNDS FOR THE PAYMENT OF FUTURE LIFE AND ANNUITY BENEFITS
 
Reserves and funds for the payment of future life and annuity benefits are
developed using actuarial methods based on statutory mortality and interest
requirements. Reserves for life insurance are computed principally on a
modified preliminary term or CRVM methods using the 1958 and 1980
Commissioners' Standard Ordinary Mortality Tables and assumed interest rates
ranging from 4% to 6%. Reserves for annuity contracts were based principally
on the 1949, 1971 and 1983 Individual Annuity Mortality Tables and assumed
interest rates ranging from 4.5% to 13.25%. Policy claims in process include
provisions for payments to be made on reported claims and claims incurred but
not reported. Any adjustments that are made to the reserve balances are
reflected in the Statements of Operations in the year in which such
adjustments are made. All policies are non-participating.
 
REVENUE AND RELATED EXPENSE RECOGNITION
 
Premiums are recognized as income over the premium payment period of the
related policies. Annuity considerations are recognized as income as they are
received. Premium and annuity considerations are recorded net of reinsurance
premiums. Benefits are reported net of the amounts received from reinsurers.
Commissions and other expenses related to the acquisition of new policies are
charged to operations as incurred.

FEDERAL INCOME TAXES
 
The Company files a consolidated federal income tax return with its parent,
Penn Mutual. The federal income tax provision or benefit is recorded to the
extent the Company's results increase or decrease the consolidated tax
liability of Penn Mutual. The resulting tax liability or receivable is paid to
or received from Penn Mutual. The provision for federal income taxes is
computed in accordance with the section of the Internal Revenue Code applicable
to life insurance companies and is based on income which is currently taxable.
In accordance with statutory accounting practices, no deferred taxes are
provided for temporary differences between pre-tax accounting income and
taxable income.
 
SEPARATE ACCOUNTS
 
Separate Account assets and liabilities represent segregated funds administered
and invested by the Company primarily for the benefit of variable annuity and
pension contractholders. The value of the assets in the Separate Accounts
reflects the actual investment performance of the respective accounts and is
not guaranteed by the Company. The carrying value for Separate Account assets
and liabilities approximates the estimated fair value of the underlying assets.
 
NOTE 2 - ACCOUNTING CHANGE:
 
The Company's parent, Penn Mutual, is required by the Internal Revenue Code
(IRC) to include the Differential Earnings Amount (DEA) in each year's taxable
income. This amount, which is allocated to the Company by Penn Mutual, is
computed by multiplying the Company's average taxable equity base by a rate
that represents the difference between stock and mutual companies' earnings
rates. Under the IRC, the enacted DEA rate for the current year is an Internal
Revenue Service (IRS) estimate and is recomputed in the following year to
reflect the actual industry results.
 
Prior to 1995, the Company recorded its portion of the federal income tax
expense for the DEA based on the enacted IRS rates for the current year along
with any adjustment to the DEA related to the recomputation of the prior year's
estimate. The portion of the Company's federal income tax expense associated
with the DEA was recorded directly to surplus.
 
In 1995, the Company changed its method of accounting for the DEA to record the
tax based on management's best estimate of the final DEA rates. The impact of
this accounting change resulted in a $2,017 direct charge to surplus in 1995.
In addition, in 1995 the Company began recording the portion of its federal
income tax expense associated with the DEA in the Statements of Operations.

Expected maturities may differ from contractual maturities because certain
borrowers have the right to call or prepay obligations with or without call or
prepayment penalties. Mortgage and other asset-backed securities consist of
commercial and residential mortgage pass-through holdings and securities
backed by credit card receivables, auto loans, home equity and manufactured
housing loans. These securities follow a structured principal repayment
schedule and are of high credit quality. These securities are rated investment
grade, other than $5,552 in commercial mortgage-backed securities retained
from the securitization of the Company's commercial mortgage loan portfolio.
The mortgage and other asset-backed securities portfolio is represented
separately in the maturity schedule due to the potential for prepayment. The
weighted average life of this portfolio is 5.5 years.
 
During 1996, 1995 and 1994, proceeds from dispositions of investments in debt
securities amounted to $165,045, $73,341 and $76,309, respectively. The gross
gains realized on those dispositions were $2,138, $2,307 and $205 and gross
losses realized on those dispositions were $363, $133 and $799 during 1996,
1995 and 1994, respectively. Net realized losses, net of taxes, transferred to
the IMR for 1996 were $570. Net realized gains, net of taxes, transferred to
the IMR were $1,413 for 1995. Net realized losses, net of taxes, transferred
to the IMR for 1994 were $70. Amortization of the IMR included in net
investment income amounted to $284 and $33 in 1996 and 1995, respectively.
Amortization of the IMR deducted from net investment income amounted to $36 in
1994.
 
The Company's investment portfolio of debt securities is comprised
predominantly of investment grade securities. As of December 31, 1996 and
1995, debt securities totaling $22,746 and $10,081, respectively, were
classified by the NAIC as less than investment grade. The Company held no debt
securities which were non-income producing for the preceding twelve months as
of December 31, 1996 and 1995.
 
MORTGAGE LOANS
 
On August 29, 1996, in conjunction with its parent, the Company securitized
the majority of its mortgage loan portfolio, by transferring mortgage loans
with a principal value of $65,852 and a book value of $65,821 to a trust which
qualifies as a REMIC (Real Estate Mortgage Investment Conduit) under the
Internal Revenue Code. The trust issued sixteen classes of Commercial Mortgage
Pass-Through Certificates with a total par value of $65,651. The certificates
evidence the entire beneficial ownership

interest in the trust. The cash flow from the mortgages will be used to repay
the certificates over an average life of 4.28. The actual date on which the
principal amount of the notes may be paid in full could be substantially
earlier or later based on the performance of the mortgages. The cash flows of
the assets of the trust will be the sole source of payments on the notes. The
Company has not guaranteed these certificates or the mortgage loans held by the
trust. As a result of this transaction, the Company recognized a loss of $2,354
upon the transfer of the mortgages to the trust, representing the difference
between the fair market value of the certificates and the book value of the
mortgage loans transferred to the trust. This loss was deferred through the
Interest Maintenance Reserve (IMR), net of related taxes, and will be amortized
into income over the remaining life of the mortgages sold.
 
Included in the Company's bond portfolio are the highest quality classes of
certificates with a par value of $60,071 and a fair market value of $61,683 at
the time of the securitization, which the Company retained. The Company sold
the lowest rated classes of certificates with a par value of $5,581 and a fair
market value of $2,086.
 
The mortgage loans which were not included in the securitization were retained
by the Company and had a book value of $19,075 and an estimated fair value of
$16,400 on the date of the securitization. Loans the Company intends to dispose
of within a period of 6 to 24 months were written down to their estimated net
realizable value. These loans had a book value of $16,389 and an estimated net
realizable value of $13,668, which resulted in a credit-related realized loss
of $2,721. The Company intends to hold mortgage loans with a book value of
$2,686 on the date of the securitization through their remaining terms. The
Company has discontinued the origination of commercial mortgage loans.
 
The following summarizes the statement value of mortgage loans by property type
and geographic concentration as of December 31, 1996 and 1995.

The Company's investments included $2,663 of mortgage loans delinquent over 60
days and no mortgage loans which were non-income producing for the preceding
twelve months as of December 31, 1996. The Company's investments did not
include any mortgage loans delinquent over 60 days as of December 31, 1995. As
of December 31, 1996 and 1995, there were no restructured mortgage loans in the
mortgage loan portfolio. Restructured mortgage loans include commercial loans
for which the basic terms, such as interest rate, amortization, maturity date,
or collateral have been changed as a result of actual or anticipated
delinquency. Restructures do not include mortgages refinanced prior to or upon
maturity at or above current market terms.
 
REAL ESTATE

</TABLE>
 
The estimated fair values for the Company's investments in debt and equity
securities are based on quoted market prices, where available. In situations
where market prices are not readily available, primarily private placements,
fair values are estimated using a formula pricing method based on fair values
of securities with similar characteristics. The fair value of currently
performing mortgage loans is estimated by discounting the cash flows associated
with the investments, using an interest rate currently offered for similar
loans to borrowers with similar credit ratings. Loans with similar credit
quality, characteristics and time to maturity are aggregated for purposes of
estimating fair value. Assumptions regarding credit risk, cash flows and
discount rates are determined using the available market and borrower-specific
information. The estimated fair value for non-performing loans is based on the
estimated fair value of the underlying real estate, which is based on recent
appraisals or other estimation techniques. The statement values of policy loans
and cash and short-term investments approximate their fair values. The
resulting estimated fair values may not be indicative of the value negotiated
in an actual sale.
 
The Company is exposed to interest rate risk on its interest sensitive
products. The Company's investment strategy is designed to minimize interest
risk by managing the duration of both assets and liabilities and anticipated
cash flows of the Company's assets and liabilities.
 
The fair value of the Company's liabilities for individual annuities is
estimated by discounting the cash flows associated with the contracts, using an
interest rate currently offered for similar contracts with maturities similar
to those remaining for the contracts being valued.

Currently, disclosure of estimated fair values is not required for all the
Company's assets and liabilities. Therefore, presentation of the estimated fair
value of a significant portion of assets without a corresponding valuation of
liabilities associated with insurance contracts can be misinterpreted. The
continuing management of the relationship between the maturities of the
Company's investments and the amounts due under insurance contracts reduces the
Company's exposure to changing interest rates.
 
NOTE 6 - FEDERAL INCOME TAXES:
 
The provision for federal income taxes differs from the normal relationship of
federal income tax to pre-tax income principally due to the mutual company DEA,
treatment of policy acquisition costs and differences in policy reserve
valuation methods.
 
NOTE 7 - REINSURANCE:
 
The Company has assumed and ceded reinsurance on certain life and annuity
contracts under various agreements. The Company remains primarily liable as the
direct insurer on all risks reinsured, and performs due diligence to ensure
that amounts due from reinsurers are collectable. The table below includes the
reinsurance amounts recorded in the accompanying financial statements, which
are presented net of reinsurance activity.

During 1994, the Company had gross premiums of $57,429, assumed premiums of
$19,625 and ceded premiums of $41,138.
 
The Company assumes and cedes certain risks under reinsurance agreements with
Penn Mutual. Net life insurance in-force assumed from Penn Mutual totaled
$327,897 and $342,694 as of December 31, 1996 and 1995, respectively. The
Company maintained reserves related to these policies of $243,426 and $242,691,
as of December 31, 1996 and 1995, respectively. Net premium and annuity
considerations assumed in connection with these agreements were $7,160 and
$8,799 in 1996 and 1995, respectively. Net premium and annuity considerations
ceded in 1994 were $10,069.
 
The Company's intercompany yearly renewable term (YRT) reinsurance treaty with
Penn Mutual, which covers certain universal life insurance products, was
modified in 1995 to provide an experience refund to be paid to the Company by
Penn Mutual in the amount of 75% of any reinsurance gain that is generated on
the products covered by the reinsurance agreement. As a result of the change to
this reinsurance treaty, $4,461 and $2,257 was received by the Company from
Penn Mutual as an experience rating refund in 1996 and 1995, respectively.
 
During 1995, the Company recaptured its single premium immediate annuity
business which it had previously ceded entirely to Penn Mutual. The transaction
resulted in the transfer of approximately $31,000 of invested assets and
policyholder liabilities from Penn Mutual to the Company.
 
NOTE 8 - RELATED PARTIES:
 
Penn Mutual has undertaken to provide sufficient financial support so that the
Company will have adequate capital and surplus as required by applicable laws
to meet its obligations to its policyholders under the terms of the Company's
policies and contracts.

Under the terms of an expense allocation agreement, the Company reimbursed Penn
Mutual for services and facilities provided on behalf of the Company, including
direct and allocated expenses. For 1996, 1995 and 1994, the total expenses
incurred under this agreement were $8,915, $6,738 and $5,391, respectively.
 
During 1996, the Company took part in an intercompany sale of securities with
Penn Mutual. The Company sold $98,000 of securities to Penn Mutual in exchange
for securities with a fair market value of $27,000 and $71,000 in cash. The
resulting gain of $499 was deferred into the IMR and will be amortized into
income over the remaining life of the securities.
 
State insurance laws limit the amount of dividends that the Company may pay to
Penn Mutual.
 
NOTE 9 - COMMITMENTS AND CONTINGENCIES:
 
The Company is a respondent in a number of proceedings, some of which involve
extra-contractual damage in addition to other damages. In addition, insurance
companies are subject to assessments, up to statutory limits, by state guaranty
funds for losses of policyholders of insolvent insurance companies. In the
opinion of management, the outcome of the proceedings and assessments are not
likely to have a material adverse effect on the financial position of the
Company.
 
The Company, in the ordinary course of business, extends commitments relating
to its investment activities. As of December 31, 1996, the Company had no
outstanding commitments relating to these investment activities.
