MESSAGE TO PARTICIPANTS IN
PROVIDENT NATIONAL'S
VARIABLE ANNUITY CONTRACTS



   This annual report of Separate Account B contains the financial statements
and portfolio information of Separate Account B for the year ended December 31,
1997.  Comparative figures that relate to Separate Account B's activities during
1997 are provided below.

    The accumulation unit value for Separate Account B increased 35.0% in 1997,
from $8.435567 at year end 1996 to $11.384926 on December 31, 1997.  Reflecting
transfers to the fixed-dollar account, as well as withdrawals and retirements,
the number of accumulation units outstanding on December 31, 1997 was 1,310,831,
down from 1,538,926 twelve months earlier.   As a result of net income from
investments, withdrawals, and net purchase payments received, total contract
owners' equity on December 31, 1997 was $16,453,121 compared to $13,917,113 on
December 31, 1996.

    The S&P 500 Index grew 33.4% in 1997.  This is the third year in a row of
greater than 20% returns for a combined three year return of 125%.  This is the
strongest string of returns in at least 70 years.  Returns were driven by double
digit earnings growth and lower interest rates.  The market was dominated by
large-company stocks; the largest capitalization quintile (top 20%) was the only
quintile to outperform the market.  Due to strong stock and bond markets, the
financial sector was the strongest sector in the market (up 48%), followed by
health care (up 44%), communication services (up 40%), consumer cyclicals (up
37%), and consumer staples (up 34%).

   The outlook for 1998 is cloudier but still favorable.  Despite Asian problems
and increased competition, the U.S. economy looks sound and inflation appears
under control.  With moderate earnings growth and stable bond yields, the stock
market can have another good year.

   Thank you for your continued support.

                        REPORT OF INDEPENDENT AUDITORS



Board of Managers and Contract Owners
Provident National Assurance Company
Separate Account B



We have audited the accompanying statements of assets and liabilities of
Provident National Assurance Company Separate Account B as of December 31, 1997
and 1996, including the schedule of investments as of December 31, 1997, and the
related statements of operations and changes in variable annuity contract
owners' equity for each of the three years in the period ended December 31,
1997, and the supplementary information for each of the ten years in the period
then ended.  These financial statements and supplementary information are the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these financial statements and supplementary information 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 and supplementary
information 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, 1997 and 1996, by correspondence with the custodian and brokers.
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 and supplementary information referred
to above present fairly, in all material respects, the financial position of
Provident National Assurance Company Separate Account B at December 31, 1997 and
1996, the results of its operations and the changes in variable annuity contract
owners' equity for each of the three years in the period ended December 31,
1997, and the supplementary information for each of the ten years in the period
then ended, in conformity with generally accepted accounting principles.

NOTES TO FINANCIAL STATEMENTS


Provident National Assurance Company Separate Account B

NOTE A--INVESTMENTS AND ACCOUNTING POLICIES

Separate Account B is a segregated investment account of Provident National
Assurance Company (a wholly-owned subsidiary of Provident Companies, Inc.) and
is registered under the Investment Company Act of 1940, as amended, as an open-
end diversified management investment company.

Common stocks and bonds are valued at published market quotations which
represent the closing sales price for securities traded on a national stock
exchange or the mean between the quoted bid and asked prices for those traded
over-the-counter.  Short-term investments are valued at cost plus accrued
interest.

Realized and unrealized gains and losses are credited to or charged to variable
annuity contract owners' equity.  The identified cost basis has been used in
determining realized gains and losses on sales of investments.  If determined on
the average cost basis, the net realized gain would have been $2,046,415,
$1,369,834 and $1,798,019 for the years ended December 31, 1997, 1996, and 1995,
respectively.  There were gross unrealized gains of $6,663,913 and gross
unrealized losses of $201,255 at December 31, 1997.  Security transactions are
recorded on the date the securities are purchased or sold which is the common
practice of the industry.  Dividends are taken into income on an accrual basis
as of the ex-dividend date.

A summary of the cost of investments purchased and proceeds from investments
sold for the three years in the period ended December 31, 1997 is shown below.
