Employee Benefits Committee of
Public Service Electric and Gas Company:

We have audited the accompanying statements of net assets available for benefits
of the Public Service  Electric and Gas Company Thrift and Tax- Deferred Savings
Plan (the "Plan") as of December 31, 1997 and 1996,  and the related  statements
of changes in net assets available for benefits for the years then ended.  These
financial  statements  are the  responsibility  of the  Plan'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 plans 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.

In our  opinion,  such  financial  statements  present  fairly,  in all material
respects, the net assets available for benefits of the Plan at December 31, 1997
and 1996,  and the changes in net assets  available  for  benefits for the years
then ended in conformity with generally accepted accounting principles.

Our audits  were  conducted  for the  purpose of forming an opinion on the basic
financial  statements taken as a whole. The supplemental  information by fund is
presented  for  the  purpose  of  additional  analysis  of the  basic  financial
statements rather than to present information regarding the net assets available
for benefits and changes in net assets  available for benefits of the individual
funds,  and is not a  required  part of the  basic  financial  statements.  This
information is the responsibility of the Plan's management. Such information has
been  subjected  to the auditing  procedures  applied in our audits of the basic
financial  statements  and, in our  opinion,  is fairly  stated in all  material
respects when considered in relation to the basic financial  statements taken as
a whole.

                          NOTES TO FINANCIAL STATEMENTS


1. SUMMARY OF THE PLAN

The Board of Directors of Public Service  Electric and Gas Company (PSE&G or the
Company)  adopted  the PSE&G  Thrift and  Tax-Deferred  Savings  Plan  (Plan) to
encourage thrift and savings by eligible employees (Eligible Employees).  It was
first  offered to Eligible  Employees in 1981.  Effective  January 1, 1996,  the
trust that holds the Plan assets was converted into the Public Service  Electric
& Gas Master  Employee  Benefit  Plan  Trust,  (Master  Trust),  a master  trust
covering all of the Company's qualified  retirement plans including the Plan and
the Public Service  Electric & Gas Company  Employee Savings Plan (Savings Plan)
(See Note 4.  Investment of the Plan and Savings Plan in the Master  Trust.) The
Plan was last amended  August 11, 1997,  effective  August 11, 1997,  except for
changes listed below,  which are effective  subsequent to December 31, 1997. The
Plan  amendments  made  during  1997  provide for the  following:  an  automatic
rebalancing  of  investment  funds;  administrative  and wording  changes  made,
including  the  transfer  of  age  and  service  credits  and   availability  of
transferred   amounts  from  the  Cash  Balance  Plan;  partial  withdrawals  of
nondeferred  deposits  and  related  earnings  permitted  after  termination  of
employment and prior to age 70 1/2.

An employee may participate in the Plan from the date of hire.  Matching Company
Contributions  begin when an employee has completed one Year of Service.  At the
time any employee who is a  Participant  in the Savings Plan becomes an Eligible
Employee for the Plan, that employee will automatically be enrolled in the Plan,
all  balances  in the  Savings  Plan  will be  transferred  to the  Plan and all
contributions  and  investment  elections  in effect for the  Savings  Plan will
remain in effect.  Participation in the Plan is entirely voluntary,  except with
respect to those employees who participated in the Employee Stock Ownership Plan
(ESOP) Fund as a result of their  participation  in the PSE&G Tax  Reduction Act
Employee Stock Ownership Plan (TRASOP) and/or the PSE&G  Payroll-Based  Employee
Stock  Ownership Plan (PAYSOP),  which plans were merged into this Plan in 1988.
Eligible  Employees are those  employees not covered by a collective  bargaining
agreement and who were hired by PSE&G or any affiliate of PSE&G participating in
the  Plan  (together   hereafter  each  called  an  "Employer"  or  collectively
"Employers").  Certain Eligible  Employees may also elect to have a distribution
from another  qualified  corporate plan  contributed as a rollover  contribution
with the approval of the Employee Benefits Committee of PSE&G  (Committee),  the
Plan Administrator.

Under the Plan,  each  participating  Employee  (Participant)  may elect to make
basic deposits to Investment  Funds of such  Participant's  choosing  within the
Thrift Account Fund of 1% - 8% of his/her  compensation  (Basic  Deposits),  and
his/her  respective  Employer  will  contribute  an amount equal to 50% thereof,
subject to certain exceptions and limitations (Employer Contributions). Employer
Contributions  with  respect to Basic  Deposits  in excess of 6% and up to 8% of
Compensation are made in shares of the Common Stock of Public Service Enterprise
Group  Incorporated  (Enterprise),  the  parent  of the  Company,  and  are  not
available  for transfer to any other Fund or  withdrawal  from the Plan prior to
the  Participant's  termination of employment.  In addition,  a Participant  may
elect  to make  supplemental  deposits  to such  Funds  in  increments  of 1% of
Compensation  up to an additional 17% of Compensation  (Supplemental  Deposits),
subject to certain  limitations,  without any  corresponding  matching  Employer
Contribution.



Participants   may  designate  such  Basic  and/or   Supplemental   Deposits  as
Nondeferred   (post-income  tax  contributions)  or  Deferred   (pre-income  tax
contributions).

Each Participant may, within any Plan Year, make one or more Additional Lump Sum
Deposits  on a  Nondeferred  basis in minimum  amounts of $250 and in such total
amounts  which,  when  aggregated  with such  Participant's  Basic  Deposits and
Supplemental  Deposits,  do not exceed 25% of his or her  Compensation  for that
Plan Year.

The maximum amount of Deferred  Deposits to a  Participant's  Thrift Account may
have to be limited to less than 25% of Compensation to meet  requirements of the
Internal  Revenue  Code of  1986,  as  amended  (IRC).  The  extent  of any such
limitation  will be determined  from time to time by the Committee  based on the
actual  pattern  of  Deferred  Deposits  by all  Participants.  If  the  maximum
permitted  percentage of Compensation  for Thrift Account  Deferred  Deposits is
reduced,   then  all  Deferred  Deposits  in  excess  of  such  percentage  will
automatically  be treated as Nondeferred  Deposits.  This will result in taxable
income to the affected Participants for Deferred Deposits in excess of any limit
so  established.  The Committee will attempt to assure that any such  limitation
will apply only to future  contributions,  but it is possible  that, in order to
meet requirements of the IRC, the limitation will, in some  circumstances,  have
to be applied  retroactively.  Deferred  Deposits may not generally be withdrawn
until age 59-1/2.  Nondeferred  Deposits, on the other hand, may be withdrawn at
any time, subject to certain penalties and restrictions.

Thrift Account Deposits are made through payroll deductions by the Participant's
Employer,  rollover contributions from other qualified plans and Additional Lump
Sum Deposits.  Deposits by Participants  and  contributions  by their respective
Employers  are  transferred  to the  Trustee and  separately  held in the Plan's
Thrift Account Fund of the Trust Fund for investment and other transactions,  as
directed by Participants.  Each Participant is entitled to choose the investment
Funds in which his/her Deposits and Employer Contributions will be invested from
among  the  investment  Funds  offered  under  the  Plan,  except  for  Employer
Contributions with respect to Basic Deposits in excess of 6%.

Bankers Trust Company is the Trustee of the Master Trust established pursuant to
the Plan.

The following Plan change was effective March 31, 1998:

 1.The merger,  for investment  management  purposes,  of the Stable Value Funds
   and the  Conservative  and  Moderate  Pre-Mixed  Portfolios  in the  Plan and
   Savings Plan.

Loan Provisions

The Trustee may,  subject to the approval of PSE&G's  Director,  Performance and
Rewards,  lend a Participant  who is employed by an Employer an amount up to 50%
of the value of the vested portion of such Participant's Thrift Account and ESOP
Fund, but no more than the aggregate value of such Participant's  Thrift Account
or $50,000,  whichever  is less.  Any  Participant  loan must be for a principal


amount  of  $1,000  or more and no  Participant  may have  more  than two  loans
outstanding at any time. All loans,  including interest thereon,  must be repaid
by payroll  deductions in equal monthly  installments  over a period of 12 to 60
months as selected by the  Participant.  However,  a Participant  may prepay any
such loan in full or in part in a lump sum in accordance  with such rules as are
prescribed by the Committee.  A Participant may not apply for more than one loan
in any calendar  year. A loan to a  Participant  is  considered an investment of
such  Participant's  Thrift  Account and  repayments  of  principal  of any loan
together with interest  thereon,  are invested in the Thrift Account  Investment
Funds of the Plan in accordance with the Participant's  then-current  investment
direction for Deposits and Employer Contributions. 

Each loan bears  interest  at a rate  fixed from time to time  by the  Committee
taking into consideration the then-current interest rates being charged by other
lenders. The rate of interest applicable to any loan at its inception remains in
effect for the duration of such loan. During 1997, the rate of interest on loans
granted to  Participants,  by quarter and starting with the first  quarter,  was
8-1/4%, 8-1/2%, 8-1/2% and 8-1/2% (See Note 2. SIGNIFICANT ACCOUNTING POLICIES -
Loans.)

2. SIGNIFICANT ACCOUNTING POLICIES

Basis of Accounting

The  financial  statements  of the Plan have been  prepared in  accordance  with
generally accepted accounting principles.

Use of Estimates

The preparation of financial  statements in conformity  with generally  accepted
accounting principles requires management to make estimates and assumptions that
affect  the  reported  amounts  of assets  and  liabilities  and  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.
Actual results could differ from those estimates.

Dividends and Interest

Dividends, interest and other income attributable to each Investment Fund of the
Plan are reinvested in that Investment Fund to the extent not used to pay direct
expenses of that investment Fund (See Expenses of Plan, below.)

All Deposits and Employer Contributions in the Stable Value Fund are invested in
either traditional Guaranteed Investment Contracts issued by insurance companies
or other  financial  intermediaries  (Traditional  GICs) or  Benefit  Responsive
Agreements  (Synthetic  GICs) which are similar to Traditional  GICs in terms of
their  ability  to  preserve  principal  and  provide a stable  rate of  return.
Synthetic  GICs are  different  in that they are backed or secured by a separate
portfolio of high-quality fixed income securities that are directly owned by the
Plan.  The portfolio is wrapped by a "book value  wrapper",  usually a financial



institution  other than the  investment  manager  of the  Synthetic  GIC,  which
provides a crediting rate and which  guarantees that benefit  repayments will be
made at book value.  Deposits and Employer  Contributions  earn  interest at the
composite rate of all GICs in which the assets of the Stable Value Fund are then
invested.  Such rate varies as such Traditional and Synthetic GICs mature or are
entered  into,  and as  Deposits  and  Employer  Contributions  are  made to and
withdrawn  from such  contracts.  Under the contracts in effect during 1997, the
composite  rate of interest  earned by such assets so invested was not less than
6.33%.

ESOP Fund  Participants  receive  quarterly  payments  directly from the Trustee
equal to the dividends  paid to the Trustee on the shares of  Enterprise  Common
Stock held for their ESOP Fund.

Valuation of Investments

The value of the  Enterprise  Common Stock Fund,  the Large  Company Stock Index
Fund, the Intermediate Government Securities Fund, the International Stock Fund,
the Mid/Small  Company Stock Fund and the shares of Enterprise Common Stock held
by the ESOP Fund is based upon  quoted  market  values.  The value of the Stable
Value Fund is based on the contract value of all GICs in which the assets of the
Stable Value Fund are  invested.  These  contracts are included in the financial
statements  at  contract  value,  which   approximates  fair  value.   Temporary
investments are valued at cost, which approximates fair market value. Securities
transactions are accounted for on the trade date.

The Plan's  financial  statements  have been  prepared  in  accordance  with the
financial reporting  requirements of the Employee Retirement Income Security Act
of 1974,  as amended  (ERISA),  as permitted  by  applicable  rules.  Under such
requirements,  realized  gains  and  losses  from  securities  transactions  are
computed using an adjusted cost basis as prescribed by the Department of Labor's
(DOL) Rules and Regulations  for Reporting and Disclosure.  The adjusted cost is
the fair value of the  security at the  beginning  of the Plan Year,  or cost if
acquired  since that date.  Unrealized  gains and losses on securities  held for
investment  are  computed  on the basis of the change in fair value  between the
beginning and end of the Plan Year.

Expenses of Plan

Effective January 1, 1997, all expenses incurred with the  administration of the
Plan,  including  taxes and brokerage  costs,  are deducted from the Trust Fund.
However,  prior to January 1, 1997, all expenses incurred in connection with the
administration  of the Plan,  including  expenses of the Trustee,  but excluding
brokerage  commissions  and taxes  relating to the sale of shares of  Enterprise
Common  Stock at the  direction  of  Participants,  were  paid  directly  by the
Employers.

The assets of the Common  Stock Fund and the ESOP Fund are invested in shares of
Enterprise  Common  Stock.  Shares of Enterprise  Common Stock  required for the
Common Stock Fund are purchased by the Trustee either directly from  Enterprise,


at its sole  discretion,  on the open  market  through a broker or from the ESOP
Fund. In situations  where the ESOP Fund is in a "sell"  position and the Common
Stock Fund is in a "buy" position,  the Common Stock Fund will buy from the ESOP
Fund at the closing  price on the New York Stock  Exchange for that day. In such
case, no brokerage  commissions are charged on the transaction.  Otherwise,  all
shares sold for the Common  Stock Fund and the ESOP Fund are sold by the Trustee
on the open market through a broker. The proceeds,  net of brokerage commissions
and transfer taxes, are distributed to the Participant. 

Loans

A loan to a Participant is considered an investment in such Participant's Thrift
Account and the principal amount of the loan is treated as a separate investment
within the various sub-accounts of the Participant's Thrift Account.  Repayments
of the principal  amount of the loan are credited to each such  sub-account  and
repayments of principal along with any accrued  interest thereon are invested in
the Plan's Investment Funds in the same manner as the Participant's then-current
investment direction for Deposits and Employer Contributions.

Loan amounts are taken from  sub-accounts of a  Participant's  Thrift Account in
the following order:

     (a)  Deferred Deposits

     (b)  Unmatured Vested Employer Contributions

     (c)  Matured Vested Employer Contributions

     (d)  Rollover Contributions

     (e)  Unmatured Post-1986 Nondeferred Deposits

     (f)  Matured Post-1986 Nondeferred Deposits

     (g)  Pre-1987 Nondeferred Deposits

Each loan is secured by an  assignment  of the  Participant's  entire
right,  title and  interest in and to the Trust Fund to the extent of
the loan and accrued  interest  thereon  (See Note 1.  SUMMARY OF THE
PLAN - Loan Provisions).

Interfund Transfers -- ESOP Fund to Thrift Account

Participants  are  permitted to transfer  all, but not less than all,  shares of
Enterprise  Common  Stock from their ESOP  Funds to their  Thrift  Accounts.  To
effect such  transfers,  the Trustee will sell the shares of  Enterprise  Common
Stock held in the ESOP Fund and invest the proceeds in the Thrift  Account Funds
designated by the Participant. The cash value of each share of Enterprise Common
Stock  transferred  will be equal to the price per  share of  Enterprise  Common
Stock  actually  received  by the  Trustee.  Any such  transfer  is treated as a
rollover contribution.

Holding Account

The  Holding  Account is a vehicle to record the  transactions  either  from one
investment  Fund to another  investment  Fund or from an  investment  Fund to an
outside  source.  Daily  balances  which  remain  in  the  Holding  Account  are
temporarily  invested in  short-term,  liquid  investments  until  disbursement.
Activity  within the  Holding  Account  includes  inflows  and  outflows of cash
related  to  investment  Fund  transfers,   Deposits,   Employer  Contributions,
withdrawals, receipts of dividends and interest, expenses incurred in connection
with the administration of the Plan, benefit payments and loan transactions.

Vesting

Employer  Contributions to a Participant's Thrift Account are immediately vested
upon a  Participant's  completion  of five years of service with the Employer or
when a Participant  is eligible for  retirement,  disabled,  laid off or dies. A
Participant  who was formerly a participant in the U.S.  Energy Partners 401 (K)
Plan (which was merged into the Plan in 1996),  will become  vested in the value
of his or her U.S. Energy Partners Employer  Contribution  Sub-account according
to the following schedule:

   Years of Service                Vested Percentage
   ----------------                -----------------
   Less than one                          0%
   One                                   20%
   Two                                   40%
   Three                                 60%
   Four                                  80%
   Five or More                         100%

All amounts credited to a Participant's ESOP Fund are fully vested.

Penalties Upon Withdrawal

If a Participant withdraws vested Employer  Contributions and/or Deposits before
they have been in the Plan for twenty-four  months,  such  Participant will lose
the matching Employer Contributions on Deposits made during the subsequent three
months.  Distributions to Participants electing to withdraw Nondeferred Deposits
and Employer  Contributions are made as soon as practicable after such elections
are received by the Plan's Record Keeper.  Nondeferred Deposits may be withdrawn
at any time but  certain  penalties  may  apply.  Deferred  Deposits  may not be
withdrawn  during   employment  prior  to  age  59-1/2  except  for  reasons  of
extraordinary  financial  hardship  and  to the  extent  permitted  by  the  IRC
(hardship  withdrawals).  Distributions  to  Participants  of approved  hardship
withdrawals are made as soon as practicable after such approval.

Rights Upon Termination

The  Company  expects and intends to  continue  the Plan  indefinitely,  but has
reserved the right to amend,  suspend or terminate  the Plan at any time. In the
event  of  termination  of the  Plan,  the  net  assets  of the  Plan  would  be
distributed  to the  Participants  based on the  balances  in  their  individual
accounts at the date of termination.




3. INVESTMENTS

The financial statements of the Plan include the following:

   A. Thrift Account Investment Funds

      (1) The assets of the Stable  Value Fund are  invested in GICs and similar
        investment  instruments issued by insurance companies or other financial
        institutions  which  contractually  provide for a guarantee of principal
        and interest for the  respective  contract  periods.  Effective  October
        1997,  PRIMCO  Capital  Management was hired to manage the assets of the
        Stable Value Fund. All contract values approximate fair values.

        The following Traditional GICs are continuing in effect:

           portfolio  providing an effective  crediting rate, as of December 31,
           1997,  of 7.19% and a contract  value of  $38,140,916.  The crediting
           rate for the Synthetic  GIC  effective  January 1, 1998 through March

        Vanguard  Group,  Inc. The  prospectus for the Stock Equities Index Fund
        indicates that such fund seeks to replicate the  investment  performance
        of the Standard  and Poor's 500  Composite  Stock Price Index.  Prior to
        September  1997,  the assets of the Large  Company Stock Index Fund were

        Fund  ("Delaware-Voyageur U.S. Government Securities Fund"), an open-end
        diversified mutual fund managed by the Delaware Management Company, Inc.
        The prospectus for the Delaware-Voyageur U.S. Government Securities Fund
        indicates  that such fund  invests  primarily  in U.S.  Treasury  bills,
        notes, bonds and other obligations issued or unconditionally  guaranteed
        by the U.S. Government, or otherwise backed by the full faith and credit
        of the U.S. Government,  and repurchase agreements fully secured by such
        obligations.

      (5) The assets of the International Stock Fund are invested in the capital
        stock  of T.  Rowe  Price  International  Funds  Inc.  ("T.  Rowe  Price
        International Stock Fund"), a no-load,  open-ended investment company or
        mutual  fund  managed  by Rowe  Price-Fleming  International,  Inc.  The
        prospectus for the T. Rowe Price International Stock Fund indicates that
        such fund invests  primarily in common stocks of  established,  non-U.S.
        companies.

      (6) The assets of the  Mid/Small  Company  Stock Fund are  invested in the
        capital  stock of the  Putnam  Vista  Fund,  an  open-ended,  investment
        company managed by Putnam Investment Management, Inc. The prospectus for
        the Putnam Vista Fund  indicates that such fund invests in a diversified
        portfolio of common stocks which may include widely-traded common stocks
        of larger companies as well as common stocks of smaller, less well-known
        companies.

        specific  percentages  within  a mix of five  existing  Plan  investment
        Funds:  40% Stable Value Fund, 20%  Intermediate  Government  Securities
        Fund, 20% Large Company Stock Index Fund, 10% International  Stock Fund,
        and  10%  Mid/Small  Company  Stock  Fund.  Every  quarter  the  Trustee
        re-aligns  this  portfolio to match its  conservative  (risk and return)
        investment strategy of 60% in bonds and 40% in stocks.

      (8) The assets of the Moderate Pre-Mix  Portfolio are invested in specific
        percentages  within a mix of five existing Plan  investment  Funds:  25%
        Large Company Stock Index Fund, 20% Stable Value Fund, 20% International
        Stock  Fund,  20%  Intermediate  Government  Securities  Fund,  and  15%
        Mid/Small  Company Stock Fund. Every quarter the trustee  re-aligns this
        portfolio to match its moderate (risk and return) investment strategy of
        60% in stocks and 40% in bonds.

      (9) The  assets  of the  Aggressive  Pre-Mix  Portfolio  are  invested  in
        specific  percentages  within  a mix of four  existing  Plan  investment
        Funds: 30% Large Company Stock Index Fund, 25% International Stock Fund,
        25%  Mid/Small  Company  Stock  Fund,  and 20%  Intermediate  Government
        Securities Fund.  Every quarter the Trustee  re-aligns this portfolio to
        match its  aggressive  (risk and return)  investment  strategy of 80% in
        stocks and 20% in bonds.

   B. ESOP Fund

      Shares of  Enterprise  Common Stock held as assets of the Plan's ESOP Fund
      were  transferred  to the Plan in 1988 as a  result  of the  spin-off  and
      merger with the Plan of the non-bargaining unit portions of PSE&G's former
      TRASOP and PAYSOP.  No additional  contributions  to or transfers into the
      ESOP Fund are presently permitted or were allowed during 1997.

4. INVESTMENT OF THE PLAN AND SAVINGS PLAN IN THE MASTER TRUST

Since January 1, 1996, the Plan's  investments  have been included in the Master
Trust which was established for the investment of assets of all of the Company's
qualified  retirement  plans  including  the  Plan  and the  Savings  Plan.  The
following tables present the fair values of and the investment income recognized
by the  investments  of the Plan and Savings  Plan in the Master Trust as of and

5. UNIT VALUE INFORMATION -- THRIFT ACCOUNT INVESTMENT FUNDS

Unit values of the  Investment  Funds are determined at the end of each business
day  (Valuation  Date) by dividing the market value of net assets  available for
benefits  by  the  number  of  units  allocated  to all  Participants  as of the
respective Valuation Date.

New units are allocated to each Participant's  Thrift Account at the end of each
business day by dividing Deposits made by, or on behalf of, such Participant for
such business day and the related Employer Contributions,  if any, together with
repayment  of the  principal  amount  of any  loan to the  Participant's  Thrift
Account, including interest paid thereon, by the unit value determined as of the
end of the Valuation Date. If a Participant makes a transfer between  Investment
Funds, makes a withdrawal, receives a distribution or a loan or makes a rollover
contribution,  the  amount so  transferred,  withdrawn,  distributed,  loaned or
rolled over is also  determined by the unit value of each  Investment Fund as of
the applicable  Valuation  Date for such  transaction.  The unit  information of
investments  by  Investment  Fund as of the last business day of each year is as
follows:

                                        Unit Value

ESOP FUND VALUATION

Enterprise  Common Stock share value is determined  by using the closing  market
price on the New York Stock  Exchange as reported in the Wall Street  Journal as
Composite  Transactions.  If a Participant  withdraws shares, the shares are, at
the Participant's  election,  either  distributed to such Participant or sold by
the Trustee and the proceeds,  net of commissions and taxes,  are distributed to
the Participant.

The  ESOP  Fund  information  as of the  last  business  day of each  year is as
follows:

                Year      Price per share         Number of shares
                ----      ---------------         ----------------
                1997         $31.6875                 167,002
                1996         $27.2500                 195,947

6. FEDERAL INCOME TAXES

The Company  believes that the Plan and its related Trust including the portions
of the former TRASOP and PAYSOP applicable to non-bargaining  unit Participants,
which portions were spun-off and merged with the Plan effective January 1, 1988,
are qualified under Sections 401(a) and 501(a) of the IRC and, as such, the Plan
is exempt from taxation on its earnings.  A determination letter to such effect,
dated  April  8,  1998,  was  obtained  from  the  Internal   Revenue   Service.
Participants are not taxed on Deferred  Deposits,  Employer  Contributions or on
the earnings  credited to their Thrift Account Fund, until  distribution of such
amounts from the Plan.

7. COMPLIANCE WITH ERISA

The Plan is  generally  subject to the  provisions  of Titles I and II of ERISA,
including the provisions with respect to reporting,  disclosure,  participation,
vesting and fiduciary responsibility.  However, it is not subject to the funding
requirements  of Title I and benefits  under the Plan are not  guaranteed by the
Pension Benefit Guarantee Corporation under Title IV of ERISA.
