REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors and Stockholders of
UniSource Energy Corporation and
to the Board of Directors of
Tucson Electric Power Company

We have reviewed the accompanying condensed consolidated balance sheet and the
related condensed consolidated statements of income and of cash flows of
UniSource Energy Corporation and its subsidiaries (the Company) and of Tucson
Electric Power Company and its subsidiaries (TEP) as of and for the three-month
and six-month periods ended June 30, 1998.  This financial information is the
responsibility of the Company's and TEP's management.  The financial statements
as of June 30, 1997 were reviewed by other independent accountants whose report
dated February 23, 1998 stated that they were not aware of any material
modifications that should be made to such financial information for it to be in
conformity with generally accepted accounting principles.

We conducted our review in accordance with standards established by the 
American Institute of Certified Public Accountants.  A review of interim 
financial information consists principally of applying analytical procedures 
to financial data and making inquiries of persons responsible for financial 
and accounting matters.  It is substantially less in scope than an audit
conducted in accordance with generally accepted auditing standards,the 
objective of which is the expression of an opinion regarding the financial
statements taken as a whole.  Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to the accompanying financial information as of and for the three-month
and six-month periods ended June 30, 1998 for it to be in conformity with
generally accepted accounting principles.

The financial statements of the Company and of TEP for the year ended December
31, 1997 were audited by other independent accountants whose report dated
February 23, 1998 expressed an unqualified opinion on those statements.

Tucson, Arizona 85701

We have reviewed the condensed consolidated statements of income of UniSource
Energy Corporation and its subsidiaries (the Company) and Tucson Electric Power
Company (TEP) for the three-month and six-month periods ended June 30, 1997 and
cash flows for the six-month period ended June 30, 1997.  These financial
statements are the responsibility of the Company's and TEP's management.

We conducted our review in accordance with standards established by the 
American Institute of Certified Public Accountants.  A review of interim 
financial information consists principally of applying analytical procedures to
financial data and of making inquiries of persons responsible for financial
and accounting matters.  It is substantially less in scope than an audit 
conducted in accordance with generally accepted auditing standards, the 
objective of which is the expression of an opinion regarding the financial 
statements taken as a whole.  Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to such condensed consolidated financial statements for them to be in
conformity with generally accepted accounting principles.

We have previously audited, in accordance with generally accepted auditing
standards, the consolidated balance sheets and statements of capitalization of
the Company and TEP as of December 31, 1997 and the related statements of
income, cash flows, and changes in stockholders' equity (deficit) for the year
then ended (not presented herein);and in our report dated February 23, 1998, we
expressed an unqualified opinion on those consolidated financial statements. In
our opinion, the information set forth in the accompanying condensed
consolidated balance sheets as of December 31, 1997 is fairly stated, in all
material respects, in relation to the consolidated balance sheets from which
they have been derived.

Item 1.  FINANCIAL STATEMENTS
- -----------------------------------------------------------------------------

The weather causes seasonal fluctuations in UniSource Energy's sales. As a
result, quarterly results are not indicative of annual operating results. The
quarterly financial statements that follow are unaudited but reflect all
normal recurring accruals and other adjustments which we believe are
necessary for a fair presentation of the results for the interim periods
presented. Also see Item 2. - Management's Discussion and Analysis of
Financial Condition and Results of Operations.  This quarterly report should
be reviewed in conjunction with the Company's 1997 Form 10-K.

The weather causes seasonal fluctuations in TEP's sales. As a result,
quarterly results are not indicative of annual operating results. The
quarterly financial statements that follow are unaudited but reflect all
normal recurring accruals and other adjustments which we believe are
necessary for a fair presentation of the results for the interim periods
presented. Also see Item 2. - Management's Discussion and Analysis of
Financial Condition and Results of Operations.  This quarterly report should

NOTE 1.  ACCOUNTING FOR THE EFFECTS OF REGULATION
- -------------------------------------------------

  Accounting Implications

     The ACC regulates TEP's utility business.  TEP generally uses the
same accounting policies and practices used by nonregulated companies
for financial reporting under generally accepted accounting principles.
However, sometimes these principles, such as FAS 71, require special
accounting treatment for regulated companies to show the effect of
regulation.  For example, in setting TEP's retail rates, the ACC may
not currently allow TEP to charge its customers to recover certain
expenses but; instead, require that these expenses be charged to
customers in the future.  In this situation, FAS 71 requires that TEP
not show these expenses on its current income statements but "defer"
these items and show them as "regulatory assets" on the balance sheet
until TEP is allowed to charge its customers.  TEP then amortizes these
items to the income statement as charges are billed to customers.
Similarly, certain items of revenue may be deferred as regulatory
liabilities, which also are eventually amortized to the income
statement.

     We have recorded regulatory assets and liabilities in our balance
sheets in accordance with FAS 71.  A regulated company must satisfy
certain conditions to apply the accounting policies and practices of
FAS 71.  These conditions include:

  - an independent regulator sets rates;
  - the regulator sets the rates to cover specific costs of delivering
service; and
  - the service territory lacks competitive pressures to reduce rates
below the rates set by the regulator.

     We periodically assess whether we continue to meet these
conditions.  If we were required to stop applying FAS 71 to all or a
portion of TEP's regulated utility operations, we would write off the
related balances of TEP's regulatory assets and liabilities as a charge
in our income statement.  In that event, our earnings would be reduced
by the net amount of regulatory assets and liabilities, after
applicable deferred income taxes.  Based on the balances of TEP's
regulatory assets and liabilities at June 30, 1998, if we ceased
applying FAS 71 to all of TEP's regulated operations, we would record
an extraordinary loss of approximately $152 million, net of the related
deferred income tax benefit of $103 million.  While our cash flows may
be affected by regulatory orders and market conditions, our cash flows
would not be affected if we ceased to apply FAS 71.

     If we stop applying FAS 71, we would need to evaluate the
likelihood that we could recover the cost of TEP's electric plant in
the marketplace using the criteria in FAS 121.  If undiscounted cash
flows are less than the carrying value of those assets, then we would
need to write off as an expense a portion of those plant assets to
reflect their current market value.  We cannot predict if we would
write off any plant assets as a result of applying FAS 121.

  Recent Events That May Impact TEP's Application of FAS 71

     Legislative and other regulatory measures are being developed in
various states to deregulate the electric generation business.  The SEC
and the EITF have been reviewing whether electric utilities should stop
applying FAS 71 to the business transactions in states where
deregulation is occurring.  In general, the EITF consensus states that
utilities must stop accounting for the electric generation portion of
their business under FAS 71 when a deregulation plan is in place and
its terms are known.  The EITF also concluded that utilities do not
need to write off regulatory assets (including those related to
generation) if the cash flow stream from regulated rates includes
recovery of the regulatory assets. We are uncertain how the EITF
consensus will impact TEP as deregulation activities develop in
Arizona.  In the future, we may need to stop applying FAS 71 to the
electric generation portion of TEP's business, even if we believe that
we will recover the full amount of our costs under the ACC competition
phase-in plan.  Approximately 55% of TEP's net regulatory assets on the
balance sheet relate to electric generation.

     In December 1996, the ACC adopted rules which would introduce
retail electric competition in Arizona. If implemented as adopted, the
rules would require each "Affected Utility" TEP, Arizona Public Service
Company, Citizens Utilities Company and several cooperatives) to open
its retail service area to competing electric service providers on a
phased-in basis over the period 1999 to 2003.  On August 5, 1998, the
ACC adopted amendments to the rules which, in part, provide a two-year
phase-in schedule in which all retail customers will have access to
competitive generation by January 1, 2001.

     On June 22, 1998, the ACC adopted an order which outlines its
policy for stranded cost recovery by Arizona utilities in a competitive
energy market.  Stranded costs represent costs recoverable by a utility
in a regulated market that would not likely be recovered through the
prices charged for electricity and other services in a competitive
market.  The order allows the Affected Utilities to choose one of the
following two methods for stranded cost recovery:

 (1) Divestiture/Auction Methodology
  - This method requires the sale of all electric generation assets
through an auction by January 1, 2001;
  - Stranded costs are calculated as the difference between book value
of generation assets (including related regulatory assets) and the
proceeds from the sale;
  - 100% of the stranded costs will be recovered over a 10-year period,
including a return on the unamortized balance;
  - All customers of Affected Utilities will pay for the stranded
costs; and
  - Affected Utilities that choose this option must file a divestiture
plan for ACC approval no later than October 1, 1998.

 (2) Transition Revenues Methodology
  - The ACC would determine the revenues necessary to maintain
financial integrity (such as avoiding default under currently existing
financial instruments); and
  - Affected Utilities would recover the determined amount of stranded
costs over a period of ten years.

     The order encourages, but does not require, full divestiture of
generating assets through an auction.  The order states that only those
Affected Utilities choosing divestiture through the Divestiture/Auction
Methodology shall have the opportunity to recover 100% of unmitigated
stranded costs.  TEP must elect one of the two stranded cost recovery
options and file an implementation plan, including its estimate of
stranded costs related to generation and regulatory assets, by August
21, 1998.  The order also specifies that some form of rate cap will be
in place for customers on standard offer electric service during the
transition period.

     TEP will cease to account for its generation operations using FAS
71 at the time the ACC approves a cost recovery plan specific to TEP,
including the specific amount of stranded costs that TEP can recover
and a cost recovery method.  The amount and method of recovery that the
ACC approves for TEP will determine whether write-offs will be incurred
at that time.  The ACC is not expected to approve a final stranded cost
recovery plan for TEP until at least the fourth quarter of 1998.  We
are unable to predict the amount of write-offs, if any, that may be
incurred at that time.

      In  May  1998  the  Arizona State Legislature  approved  and  the
Governor  signed  a  bill regarding retail electric  competition.   The
legislation requires the introduction of customer choice to 20% of each
utility's  retail load by December 31, 1998 and to all  utility  retail
customers by December 31, 2000.  This legislation only relates directly
to  public  power  entities such as SRP; however, the  bill  encourages
broader application of the legislation's principles by the ACC  to  the
state's investor-owned utilities, including TEP, and cooperatives.

      We  cannot  predict the outcome of the legislation or  the  ACC's
retail competition rules.  Additionally, federal legislators introduced
several  retail competition initiatives in Congress which,  if  passed,
could  modify or override the actions taken by the ACC or  the  Arizona
Legislature.

NOTE 2.  TAX ASSESSMENTS
- ------------------------

  Ruling on Arizona Sales Tax Assessments - Coal Sales

     We have received sales tax assessments from the ADOR alleging that
Valencia is liable for sales tax on gross income from coal sales,
transportation and coal-handling services provided to TEP from November
1985 through May 1996.  We have protested these assessments.  In
September 1996, the Arizona Court of Appeals upheld the validity of the
assessment issued for the period November 1985 through March 1990.  In
May 1998, the Arizona Supreme Court remanded the case back to the
Arizona Tax Court to be reheard.  We are also protesting the
assessments for the period April 1990 through May 1996.

     We have previously recorded an expense and a related liability for
the sales taxes and interest that we believe are probable of incurrence
for the period November 1985 through May 1996.  Arizona law generally
requires payment of an assessment prior to pursuing the appellate
process.  We previously paid, under protest, a total of $23 million of
the disputed sales tax assessments.  These payments will be refunded if
we are successful in the appeals process.

     On May 31, 1996, Valencia was merged into TEP.  Because TEP now
acquires coal directly from other companies, we do not believe we are
liable for sales tax computed on a basis similar to the assessments
described above after May 31, 1996.  For periods prior to May 31, 1996,
we continue to record an estimated interest expense on the disputed
assessments.

  Arizona Sales Tax Assessments - Leases

     The ADOR has issued sales tax assessments to some of TEP's lessors
of generation-related facilities and equipment.  The assessments allege
sales tax liability on a component of rents we paid on the
Springerville Unit 1 Leases, the Springerville Common Facilities
Leases, the Irvington Lease and the Springerville Coal Handling
Facilities Lease from August 1, 1988 to June 30, 1997.  Due to
indemnification provisions in the lease agreements, if the ADOR
prevails, we would be required to reimburse the lessors for the sales
taxes that they pay.  We filed an appeal of the assessments in the
Arizona Tax Court in February 1998.  In July 1998, the Arizona Tax
Court ruled against us on the Irvington lease.  We plan to appeal the
Tax Court's decision.

     We have recorded a liability for the probable amount of sales
taxes and interest due as of June 30, 1998.  If the ADOR prevails, we
would need to record an additional expense and related liability.  Even
though it is reasonably possible that the resolution of this issue
could result in approximately $22 million of additional sales tax
expense, we do not believe this outcome is likely.  We do not expect
that the resolution of this assessment will have a material negative
impact on the financial statements. We believe that the ultimate
resolution of this issue will occur over a period of two to four years.

  INCOME TAX ASSESSMENTS

     In February 1998, the IRS issued an income tax assessment for the
1992 and 1993 tax years.  The IRS is challenging our treatment for
income tax purposes of various items relating to the 1992 Financial
Restructuring, including the amount of NOL and ITC generated before
December 1991 that may be used to reduce taxes in future periods.

     Due to the Financial Restructuring, a change in ownership of TEP
occurred for tax purposes in December 1991.  As a result, the use of
the NOL and ITC generated before December 1991 may be limited under the
tax code.  The IRS is challenging our calculation of this limitation.
At June 30, 1998, pre-change federal NOL and ITC carryforwards were
approximately $267 million and $26 million, respectively.  In addition
to the pre-change NOL and ITC which are subject to the limitation, $166
million of federal NOL at June 30, 1998, is not subject to the
limitation.

     Resolution of this matter is not expected to have a material
adverse impact on the financial statements.

NOTE 3.  TRANSFER OF MEH FROM TEP TO UNISOURCE ENERGY
- -----------------------------------------------------

     On January 1, 1998, TEP became a subsidiary of UniSource Energy.
At the same time, TEP transferred MEH to UniSource Energy and received
as consideration from UniSource Energy a $95 million 10-year promissory
note with a yearly interest rate of 9.78%.  Approximately $25 million
of this note represents a gain to TEP.  TEP has not recorded this gain.
Instead, this gain will be reflected as an increase in TEP's common
equity when UniSource Energy pays the principal portion of the note.
The note receivable appears on TEP's consolidated balance sheet but
does not appear on UniSource Energy's consolidated balance sheet
because intercompany balances and transactions are eliminated when
financial statements are consolidated.

     MEH owns Advanced Energy Technologies, Inc., Millennium Energy
Holdings, Inc., Nations Energy Corporation and Southwest Energy
Solutions, Inc.

     The transfer of MEH's cash balance of $45.4 million as part of the
transfer of MEH to UniSource Energy is included in the Cash Flows from
Investing Activities in TEP's cash flow statement for the six months
ended June 30, 1998.

NOTE 4.  LOANS AND GUARANTEES FOR NEV
- -------------------------------------

     In December 1997, Millennium committed to provide NEV with $20
million of funding.  At July 31, 1998, NEV had received the following
under the $20 million commitment:

 - Millennium provided $10 million in loans to NEV.
 - Millennium provided $4 million for NEV preferred equity.
 - UniSource Energy issued guarantees in the aggregate amount of $5.5
million to secure the obligations of NEV to counterparties to energy
purchase and sale agreements.

As a result of these loans and guarantees, the remaining commitment
amount available was $0.5 million at July 31, 1998.

     UniSource Energy is the guarantor of $32.8 million of performance
bonds that secure the amounts NEV California owes to the California
utility distribution companies (UDCs) for services provided by the UDCs
in connection with NEV California's sales in the California retail
electric market.  NEV California bills its customers for these UDC
charges.

     In August 1998, UniSource Energy agreed to guarantee a $10 million
loan that NEV obtained from an unrelated party.  The debt underlying
the guarantee is not due until 1999.

     From September 1997, the inception of Millennium's ownership in
NEV, through June 30, 1998, Millennium recorded approximately $23.8
million of NEV losses.  The amount equals the total funds and
commitments provided by Millennium and UniSource Energy to NEV.
Accounting principles limit the amount of the loss to be recorded by
Millennium to the total amount invested and committed by Millennium and
UniSource Energy.  Under its current obligations, NEV is expected to
continue to incur losses and require additional funds to fulfill its
obligations.  Should Millennium or UniSource Energy provide additional
funding to NEV, the amounts provided would need to be immediately
expensed if NEV has incurred losses in excess of $23.8 million since
September 1997.  NEV is seeking sources other than Millennium and
UniSource Energy to provide necessary funding.  There can be no
assurance that any such financing will be obtained.

NOTE 5.  LONG-TERM DEBT
- -----------------------

     In March 1998, the Apache County, Arizona Industrial Development
Authority issued $200 million of Pollution Control Revenue Bonds and
loaned the proceeds to TEP.  The new bonds, which are unsecured, were
sold in three series: Series A ($83.7 million) bears interest at 5.85%
and matures in 2028; Series B ($99.8 million) bears interest at 5.875%
and matures in 2033; and Series C ($16.5 million) bears interest at
5.85% and matures in 2026.  The proceeds from the issuance of the new
bonds were used in May 1998 to redeem $200 million of previously issued
variable interest rate bonds that would have matured in 2020 and 2021.

     On May 15, 1998, TEP exchanged $46.9 million of its existing
12.22% First Mortgage Bonds due 2000 for an identical amount of new
12.22% Exchange Series First Mortgage Bonds due 2000.  With the
exception of the elimination of a covenant restricting the payment of
dividends, the new bonds have substantially the same terms and
conditions as the existing bonds.

     On August 4, 1998, TEP issued $140 million of First Collateral
Trust Bonds, Series A, and will use the proceeds on September 3, 1998
to redeem all of its First Mortgage Bonds due in 1999, 2001, 2002 and
2003, as well as $31.9 million of 12.22% First Mortgage Bonds due 2000
not tendered for exchange as described above.  The bonds to be redeemed
bear interest at rates ranging from 7.55% to 12.22%.  When TEP redeems
these bonds, covenants that currently prohibit TEP from paying common
stock dividends so long as it has an accumulated earnings deficit will
be eliminated.  Dividends would thereafter be permitted if certain
other, more flexible financial covenants have been met.  The First
Collateral Trust Bonds bear interest at 7.50% and mature in 2008.  The
First Collateral Trust Bonds are secured by an equal aggregate
principal amount of bonds issued under TEP's General First Mortgage and
held by the trustee.

NOTE 6.  RATE MATTERS
- ---------------------

  SHARED SAVINGS PROPOSAL

     On July 9, 1997, TEP filed with the ACC a request for an annual
rate reduction of $6.8 million (or 1.1%) for retail customers.  This
filing is in the form of a Shared Savings Proposal (SSP) which includes
a sharing of cost containment benefits with customers and a reduction
of potentially stranded costs associated with the introduction of
retail electric competition in Arizona.    The SSP identifies $20.8
million in savings allocable to ACC jurisdictional operations.  The
cost containment savings were realized primarily from renegotiated fuel
contracts and a 15% reduction in our workforce from the 1996 Voluntary
Severance Program.  The ACC has not set a date to decide on this
matter.

     The proposed $6.8 million rate reduction represents an equal
sharing between TEP and its customers of $13.6 million of the cost
savings.  The SSP would allow TEP to use the remaining $7.2 million of
cost savings to reduce (mitigate) potentially stranded costs by
accelerating the amortization of Retail Excess Capacity Deferrals.
Retail Excess Capacity Deferrals represent operating and capital costs
associated with Springerville Unit 2 capacity which the ACC did not
allow TEP to recover in rates until the 1994 and 1996 Rate Orders.
These Retail Excess Capacity Deferrals totaled $86.3 million and $88.7
million at June 30, 1998 and December 31, 1997, respectively.  These
deferrals are only reflected in our regulatory calculations.  The
accompanying balance sheets do not include these deferrals as the costs
were expensed when incurred for financial reporting purposes.  The
proposed $7.2 million (after tax) increase in annual amortization
expense for those excess capacity deferrals would decrease the
amortization period from 20 years to 5.6 years as of December 1996.
The proposed increase in amortization expense would be reflected in
TEP's regulatory accounting records but would have no impact on the
expenses included in the financial statements.

  SPRINGERVILLE COAL CONTRACT TERMINATION FEE

     On June 27, 1997, TEP signed an agreement with the coal supplier
for the Springerville Generating Station to terminate the then-existing
coal supply contract and enter into a new, more cost effective contract
with the same supplier.  TEP paid a $50 million termination fee in
three installments:  $30 million paid on June 30, 1997; $10 million
paid on September 30, 1997; and $10 million paid on March 31, 1998.

     TEP asked the ACC, as part of the SSP, to allow the termination
fee to be recorded as a regulatory asset and to be amortized to fuel
expense over the 13-year term of the new agreement.  On July 29, 1997,
the ACC issued an interim accounting order allowing TEP to defer the
$50 million termination fee as a regulatory asset in the balance sheet
until the ACC decides whether the $50 million termination fee should be
recovered through retail rates.  The interim accounting order also
allowed TEP to begin amortizing the termination fee to fuel expense.
If the ACC ultimately disallows recovery, the unamortized portion of
the $50 million termination fee would be expensed immediately.  The ACC
has not set a date to decide on this matter.

     The reduction in the valuation allowance and corresponding NOL
benefit in 1997 are primarily due to revisions in the estimated amount
of NOLs that we expect to offset future taxable income.  As of December
31, 1997, both UniSource Energy and TEP had recorded the amount of
prior period NOL benefit that we expect to utilize on future income tax
returns.  At the present time, we are not able to estimate future
additional amounts of NOL benefit that we may recognize in the income
statements of either UniSource Energy or TEP.  This is because there
are still open tax years for which there may be additional assessments
and because federal and state NOL carryforwards have varying expiration
dates.  We do not expect to recognize additional amounts of NOL benefit
until such items are resolved.

NOTE 8.  NEW ACCOUNTING STANDARD
- --------------------------------

      In  June  1998, the Financial Accounting Standards  Board  issued
Statement  of  Financial  Accounting  Standards  No.  133  (FAS   133),
Accounting  for  Derivative Instruments and Hedging  Activities.   This
Statement  requires  that  all  derivative  financial  instruments   be
recognized  as  either  assets or liabilities  in  the  balance  sheet.
Measurement is at fair value and if the derivative is not designated as
a  hedging instrument, changes in fair values (i.e., gains and  losses)
are  to  be recognized in earnings in the period of change.  If certain
conditions  are met, a derivative may be designated a hedge,  in  which
case  the  accounting  for changes in fair value  will  depend  on  the
specific  exposure being hedged.  The Company is required to adopt  FAS
133  in the first quarter of 2000.  We are still evaluating the impact,
if  any,  that  the  adoption of FAS 133 will  have  on  our  financial
statements.

NOTE 9.  RECLASSIFICATIONS

NOTE 10.  REVIEW BY INDEPENDENT PUBLIC ACCOUNTANTS
- --------------------------------------------------

     With respect to the unaudited consolidated financial information
of UniSource Energy and TEP for the three-month and six-month periods
ended June 30, 1998, PricewaterhouseCoopers LLP reported that they have
applied limited procedures in accordance with professional standards
for a review of such information. However, their separate report dated
August 4, 1998, appearing herein, states that they did not audit and
they do not express an opinion on that unaudited consolidated financial
information.  PricewaterhouseCoopers LLP has not carried out any
significant or additional audit tests beyond those which would have
been necessary if their report had not been included.  Accordingly, the
degree of reliance on their report on such information should be
restricted in light of the limited nature of the review procedures
applied.  PricewaterhouseCoopers LLP is not subject to the liability
provisions of section 11 of the Securities Act of 1933 for their report
on the unaudited consolidated financial information because that report
is not a "report" or a "part" of a registration statement prepared or

ITEM 2. - MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS
- ---------------------------------------------------------------------------

     UniSource Energy is a holding company which owns all of the
outstanding common stock of TEP and MEH.  TEP is an operating public
utility engaged in the generation, purchase, transmission, distribution and
sale of electricity for customers in the greater Tucson, Arizona area and
to wholesale customers.  MEH owns all of the outstanding common stock of
four subsidiaries established for the purpose of operating or investing in
various unregulated energy-related businesses.

     TEP is the principal subsidiary of UniSource Energy and accounts for
substantially all of its assets, revenues and net income.  The financial
condition and results of operations of TEP are currently the principal
factors affecting the financial condition and results of operations of
UniSource Energy on an annual basis, although losses from energy-related
ventures of MEH and its subsidiaries have resulted in losses reported by
the Company for the six-months ended June 30, 1998.

     Management's Discussion and Analysis explains the general financial
condition and the results of operations for UniSource Energy and its
business subsidiaries including:

  -  operating results during the second quarter and the first six months
     compared with the same periods in the prior year,
  -  the outlook for dividends on common stock,
  -  changes in liquidity and capital resources during the second quarter
     and first six months of 1998, and
  -  expectations of identifiable material trends which may affect our
     business in the future.

     Management's Discussion and Analysis should be read along with the
Company's Condensed Consolidated Financial Statements, beginning on page 3,
which present the results of operations for the quarters and the six month
periods ended June 30, 1998 and 1997.  Management's Discussion and Analysis
analyzes and explains the differences between periods for specific line
items of the Condensed Consolidated Financial Statements.

OVERVIEW
- --------

     UniSource Energy recorded net income of $1.1 million for the quarter
ended June 30, 1998, and a net loss of $6.0 million for the first six
months of 1998.  This compares with net income of $29.9 million in the
second quarter and $41.4 million for the first six months of 1997.

     Our results in the second quarter of 1998 were affected primarily by
the following factors: losses from unregulated energy-related subsidiaries
($5.6 million after-tax), lower non-cash regulatory revenues ($3.1 million
pre-tax), and higher interest expense ($3.4 million pre-tax).  Also, the
results in the second quarter of 1997 included the effect of the following
non-recurring items:

  -  $15.0 million net operating loss carryforward tax benefits,
  -  $10.2 million in pre-tax other income from a reversal of loss
     provision,  and
  -  $2.6 million in pre-tax consulting fees paid to NEV.

Excluding these adjustments, we would have recorded net income of $10.4
million in the second quarter of 1997. These changes are discussed in more
detail in Results of Operations and Investments in Energy-Related
Affiliates, below.

     Our results in the first six months of 1998 were affected primarily by
the following factors: losses from unregulated energy-related subsidiaries
($9.7 million after-tax), lower non-cash regulatory revenues ($8.1 million
pre-tax), and higher interest expense ($7.6 million pre-tax).  The results
of the first six months of 1997 also included the effects of the following
non-recurring items:

  -  $29.3 million net operating loss carryforward tax benefits,
  -  $10.2 million in pre-tax other income from a reversal of loss
     provision,
  -  $2.9 million in pre-tax VSP expense, and
  -  $3.7 million in pre-tax consulting fees paid to NEV.

Excluding these adjustments, net income would have been $10.0 million in
the first six months of 1997. These factors are discussed in more detail in
Results of Operations and Investments in Energy-Related Affiliates, below.

     The Company's and TEP's financial prospects are subject to regulatory,
economic, and other uncertainties.  These uncertainties include the extent
to which TEP can alter operations and reduce costs in response to industry
changes or unanticipated economic downturns, which may be limited by
continued high financial and operating leverage.  Our future success will
depend, in part, on our ability to contain and/or reduce the costs of
serving retail customers and the level of sales to those customers.  Until
the uncertainties surrounding the introduction of retail competition in
Arizona are resolved, predicting the level of TEP's future energy sales and
the composition of its future revenues is difficult.  However, we expect
retail competition will exist in our local market within the next three
years.  See Competition, Retail below.  In a deregulated environment,
revenues from energy sales will be less certain, although revenues from
transmission and distribution services, which we expect to remain
regulated, would likely continue to grow.  Even in a deregulated
environment, TEP expects to continue to benefit from population and
economic growth in the Tucson area through increased revenues from its
regulated distribution services.

     The Company's financial prospects are also subject to uncertainties
relating to the start-up and developmental activities of the unregulated
energy-related affiliates.  Although the Company's investments in
unregulated energy-related affiliates comprise less than 1% of total
assets, start-up costs and other subsidiary developmental activities have
contributed to losses from these activities in 1998.  These losses have
contributed to the losses reported by the Company for the six-month period
ended June 30, 1998.

     The Company is addressing the uncertainties discussed above and is
positioning itself to benefit from the changing regulatory environment.  We
are improving cost measurement and management techniques and are re-
engineering various functions at TEP.  We have also extended contracts,
where appropriate, for large wholesale and retail customers, and are
developing new affiliates to provide energy services to markets beyond
TEP's retail service territory.  See Competition, Retail; Shared Savings
Proposal; Investments in Energy-Related Affiliates; and Results of
Operations below.

     Since April 1997, we have made significant progress in our financial
strategy to reduce refinancing risk by extending maturities of long-term
debt and letters of credit and to reduce exposure to variable interest
rates by refinancing with fixed interest rates.  TEP refinanced variable
rate debt obligations at fixed rates and entered into a new bank Credit
Agreement to replace the MRA.  On August 4, 1998, TEP issued bonds to
refinance all of the First Mortgage Bonds that prohibit the payment of
dividends, and called for the redemption of these bonds (which mature
between 1999 and 2003) on September 3, 1998.  See Financing Developments,
TEP First Mortgage Bonds and Dividends on Common Stock, below.

     Despite these improvements, TEP's and UniSource Energy's consolidated
capital structures remain highly leveraged and include $329 million of
variable rate debt obligations which will impact TEP's earnings and cash
flow if interest rates change.

     During the next twelve months, TEP expects to fund its operating
activities and construction expenditures with internal cash flows, existing
cash balances, and, if necessary, borrowings under the Revolving Credit.
As of August 7, 1998, cash balances, including cash equivalents for
UniSource Energy, were approximately $132 million, of which $102 million
was held by TEP and its consolidated subsidiaries.


COMPETITION
- -----------

    RETAIL

      Under current law, TEP does not compete with other companies for
electric service in TEP's retail service territory.   However, TEP competes
against gas service suppliers and others who provide energy services.  TEP
actively markets energy and customized energy-related services.  We have
not lost any customers to self-generation partly because of these efforts.
For example, in recent years, TEP executed new contracts with two principal
customers that provide approximately 9% of TEP's total annual retail
revenues.  Both customers are in the copper mining business.  The new
contracts include price reductions, term extensions, and a provision for
interruptible service.  These contracts expire in March 2001 and January
2003.  These mining customers cannot terminate the contracts early without
giving us at least one and up to two years prior notice.  We have not
received any such notices.

     Retail Electric Competition Rules

     In December 1996, the ACC adopted rules that require a phase-in of
retail electric competition in Arizona beginning January 1, 1999.  The
rules were adopted as a framework to implement competition.  On August 5,
1998 the ACC adopted amendments to the rules which, in part, provide a two-
year phase-in schedule in which all retail customers will have access to
competitive generation by January 1, 2001.

     The key provisions of the rules include the following:

  -  Each Affected Utility shall make available at least 20% of its 1995
     system retail peak demand for competitive generation supply on a
     first-come, first-served basis, as follows: (1) All Affected Utility
     customers with non-coincident peak demand load of 1 MW or greater will
     be eligible for competitive electric services no later than January 1,
     1999.  (2) Groups of Affected Utility customers with individual non-
     coincident peak load demands of 40 kW or greater aggregated into a
     combined load of 1 MW or greater will also be eligible for competitive
     service no later than January 1, 1999.  Each Affected Utility shall
     also offer a residential phase-in program with a minimum of 1/2 of 1%
     of residential customers having access to competitive electric
     services on January 1, 1999, with the number of customers eligible in
     this program to increase by 1/2 of 1% every quarter until January 1,
     2001.  All retail customers shall be entitled to obtain competitive
     electric services no later than January 1, 2001.

     TEP currently serves about 80 customers who qualify under the 1 MW or
     greater category described above, representing 351 MW of load.  Of
     this load, 60% is under contract through 2001.

  -  Each Affected Utility shall file a report detailing possible
     mechanisms to provide benefits, such as rate reductions of 3% - 5%, to
     all Standard Offer customers.

  -  Each Affected Utility shall make available to all customers in its
     service territory Standard Offer bundled generation, transmission,
     ancillary, distribution and other necessary services at regulated
     rates.  After January 1, 2001, Standard Offer service shall be
     provided by the Affected Utilities, which will become Utility
     Distribution Companies (UDCs), who shall also act as providers of last
     resort.

  -  The Affected Utilities shall provide non-discriminatory open access to
     transmission and distribution facilities to serve all customers.  The
     ACC supports the development of an Independent System Operator (ISO)
     or, absent an ISO, an Independent Scheduling Administrator (ISA).

  -  All competitive generation assets and services shall be separated from
     an Affected Utility prior to January 1, 2001.  Such separation shall
     either be to an unaffiliated party or to a separate corporate
     affiliate or affiliates.  If an Affected Utility chooses to transfer
     its competitive generation assets or competitive services to a
     competitive electric affiliate, such transfer shall be at a value
     determined by the ACC to be fair and reasonable.

      Appeal of ACC Order

      In February 1997, TEP filed in the Arizona Superior Court an appeal
of the ACC order adopting the rules. TEP filed a motion for summary
judgment, claiming, among other things that the Competition Rules:  (a)
violated the Regulatory Compact between TEP and the State of Arizona; (b)
confiscated TEP's property; and (c) violated due process.  The Court did
not grant summary judgment but ruled that the Commission must hold hearings
before it can modify TEP's Certificate of Convenience and Necessity (CC&N).
No trial date has been set in the case and no final order has been issued.
We are unable to predict the outcome of the appeal.

      Stranded Cost Recovery

      On June 22, 1998, the ACC adopted an order which outlines its policy
for stranded cost recovery by Arizona utilities in a competitive energy
market.  The order is an amended version of the original order proposed by
the ACC Hearing Officer on May 6, 1998.  The proposed order was discussed
in the Company's and TEP's Report on Form 10-Q for the period ended March
31, 1998.

      The order provides two methods for stranded cost recovery for the
Affected Utilities: (1) Divestiture/Auction Methodology and (2) Transition
Revenues Methodology.  The order encourages, but does not require, full
divestiture of generating assets through an auction to unaffiliated third
parties.  The order states that only those Affected Utilities choosing
divestiture through the Auction/Divestiture Methodology shall have the
opportunity to recover 100% of unmitigated stranded costs.  The key
components of the order are summarized below:

     Divestiture/Auction Methodology
     -------------------------------

  -  Affected Utilities choosing divestiture through the auction method
     must file a divestiture plan for ACC approval no later than October 1,
     1998.  Divestiture must be completed by January 1, 2001.

  -  The amount of stranded costs shall be the difference between the value
     of generation assets (generating plants, purchased power contracts,
     fuel contracts, and related regulatory assets) under traditional
     regulation and the market value of the assets after divestiture.  The
     definition of stranded costs shall include reasonable costs incurred
     for premiums, penalties or other payments necessary to effect
     divestiture, income tax ramifications of divestiture, redemption costs
     associated with tax-exempt two-county debt which may have to be
     redeemed upon transfer of the assets, and other reasonable costs
     necessarily incurred to accomplish divestiture.  Unmitigated stranded
     costs shall also include reasonable employee severance and retraining
     costs necessitated by electric competition.

  -  An Affected Utility shall be permitted to collect 100% of its stranded
     costs, including a return on its unamortized balance over a ten-year
     period, with a true-up mechanism.

  -  The ACC will work with the Affected Utility to provide sufficient
     assurances in order to avoid triggering write-offs related to the
     application of FAS 71.

  -  An Affected Utility's generation affiliate may acquire the generation
     assets of its parent or sister company, or the generation assets of
     another Affected Utility in the auction if it establishes that it is
     the highest bidder and that the acquisition will not result in the
     entity having more than 40% of the state's total generation megawatts
     of capacity.

  -  An Affected Utility that divests all its generation costs to non-
     affiliated entities, that results in negative stranded costs (not
     including regulatory assets), shall be entitled to keep 50% of the
     negative stranded costs.

  -  All Affected Utilities' customers shall pay their appropriate share of
     stranded costs either through a Competitive Transition Charge (CTC) or
     a standard offer rate, collected over a maximum of ten years.

     Transition Revenues Methodology
     -------------------------------

  -  The order states that "this option would be to provide sufficient
     revenues necessary to maintain financial integrity, such as avoiding
     default under currently existing financial instruments for a period of
     ten years, at the end of which time there would be no remaining
     stranded costs, or for the Commission to otherwise provide an
     allocation of stranded cost responsibilities and risks between
     ratepayers and shareholders as is determined to be in the public
     interest for a given Affected Utility."

      Each Affected Utility must file its choice of options for stranded
cost recovery by August 21, 1998.  In addition, the Affected Utility will
need to file an implementation plan that would include the following items,
if appropriate, for their option choice: the estimation of stranded costs
separated out into regulatory assets and other generation related assets; a
preliminary plan for auction/divestiture; the minimum financial ratios to
maintain financial viability for ten years; the amount of regulatory assets
requested, how much of those assets are generation related, and the
Commission Decision Number that approved such assets; and other information
as necessary.

     TEP will cease to account for its generation operations using FAS 71
at the time the ACC approves a cost recovery plan specific to TEP,
including the specific amount of stranded costs that TEP can recover and a
determination of a cost recovery method.  The amount and method of recovery
that the ACC approves for TEP will determine whether write-offs will be
incurred at that time.  The ACC is not expected to make a final
determination of a stranded cost recovery plan for TEP until at least the
fourth quarter of 1998.  We are unable to predict the amount of write-offs,
if any, that may be incurred at that time.

      State and Federal Legislative Initiatives on Retail Electric
      Competition

      A legislative study committee established by the Arizona Legislature
issued a report on retail electric competition in December 1997.  The
report identified tax and other issues for the legislature to address.  In
January 1998, Arizona legislators introduced HB 2663 regarding the
implementation of retail electric competition in Arizona.  This bill was
passed by the Arizona State Legislature and signed by the Governor in May
1998.  The legislation requires the introduction of customer choice to 20%
of each utility's retail load by December 31, 1998 and to all utility
retail customers by December 31, 2000. This legislation only relates
directly to public-power entities such as SRP; however, the bill encourages
broader application of the legislation's principles by the ACC to the
state's investor-owned utilities, including TEP, and cooperatives.

       We believe that certain matters in the ACC's current retail
competition rules may require legislative changes, while others may require
amendments to the Arizona state constitution.  Additionally, federal
legislators introduced several retail competition initiatives in Congress
which, if passed, could modify or override the actions taken by the ACC or
the Arizona Legislature.  Congress is not expected to act on the
legislation in 1998.  We will continue to assess the likely impact on TEP
of the ACC's retail competition rules, proposed legislation, and other
potential market reforms.  We are unable to predict the ultimate impact of
increased retail competition on future results of our operations.  See
Accounting for the Effects of Regulation below for a discussion of the
potential impact of increased competition on the Company's accounting
policies.

   WHOLESALE

     TEP competes with other utilities, marketers and independent power
producers in the sale of electric capacity and energy in the wholesale
market.  FERC generally does not permit TEP's prices for wholesale sales of
capacity and energy to exceed rates determined on a cost of service basis.
However, in the fall of 1997, FERC granted TEP a tariff to sell at market-
based rates.  In the current market, wholesale prices are substantially
below total cost of service, but in all instances, we make wholesale sales
at prices which exceed fuel and other variable costs.  In addition, we
expect competition to sell capacity to remain vigorous.  Prices may remain
depressed for at least the next several years due to increased competition
and surplus capacity in the southwestern United States.  Competition for
the sale of capacity and energy is influenced by the following factors:

  -  availability of capacity in the southwestern United States,
  -  the availability and prices of natural gas and oil,
  -  spot energy prices, and
  -  transmission access.

     The FERC issued two orders pertaining to transmission access in April
1996.  FERC Order No. 888 requires all public utilities that own, control,
or operate interstate transmission facilities to offer transmission service
to others under a single tariff.  This tariff must incorporate certain
minimum terms and conditions of transmission service established by the
FERC and must also be used by public utilities for their own wholesale
market transactions.  Transmission and generation services for new
wholesale service are to be unbundled and priced separately.  FERC Order
No. 889 requires transmission service providers to establish or participate
in an open access same-time information system (OASIS) that provides
information on the availability of transmission capacity to wholesale
market participants.  The order also establishes standards of conduct to
prevent employees of a public utility engaged in marketing functions from
obtaining preferential access to OASIS-related information or from engaging
in discriminatory business practices.  TEP is in compliance with the
requirements of FERC Orders 888 and 889.

     TEP, along with other transmission owners and users located in the
southwestern United States, is investigating the feasibility of forming an
ISO for the region.  An ISO would be responsible for ensuring transmission
reliability and nondiscriminatory access to the regional transmission grid.
Over 50 participants have signed a Development Agreement and expect to
complete the detailed developmental work by the end of 1998.  The formation
of an ISO would be subject to approval by the FERC and state regulatory
authorities in the region.  The financial aspects of forming an independent
system operator, including the potential effects on TEP's future results of
operations, will be examined as part of the development work.

SHARED SAVINGS PROPOSAL
- ------------------------

     On July 9, 1997, TEP filed with the ACC a request for an annual rate
reduction of $6.8 million (or 1.1%) for retail customers.  This filing is
in the form of a Shared Savings Proposal (SSP) which includes a sharing of
cost containment benefits with customers and a reduction of potentially
stranded costs associated with the introduction of retail electric
competition in Arizona. The SSP identifies $20.8 million in savings
allocable to ACC jurisdictional operations. The cost containment savings
were realized primarily from renegotiated fuel contracts and a 15%
reduction in our workforce from the 1996 Voluntary Severance Program.  The
ACC has not set a date to decide on this matter.

     The proposed $6.8 million rate reduction represents an equal sharing
between TEP and its customers of $13.6 million of the cost savings.  The
SSP would allow TEP to use the remaining $7.2 million of cost savings to
reduce (mitigate) potentially stranded costs by accelerating the
amortization of Retail Excess Capacity Deferrals.  Retail Excess Capacity
Deferrals represent operating and capital costs associated with
Springerville Unit 2 capacity which the ACC did not allow TEP to recover in
rates until the 1994 and 1996 Rate Orders.  These Retail Excess Capacity
Deferrals totaled $86.3 million and $88.7 million at June 30, 1998 and
December 31, 1997, respectively.  These deferrals are only reflected in our
regulatory calculations.  The accompanying balance sheets do not include
these deferrals as the costs were expensed when incurred for financial
reporting purposes.  The proposed $7.2 million (after-tax) increase in
annual amortization expense for those excess capacity deferrals would
decrease the amortization period from 20 years to 5.6 years as of December
1996.  The proposed increase in amortization expense would be reflected in
TEP's regulatory accounting records but would have no impact on the
expenses included in the financial statements.

ACCOUNTING FOR THE EFFECTS OF REGULATION
- ----------------------------------------

     The ACC regulates TEP's utility business.  TEP generally uses the same
accounting policies and practices used by nonregulated companies for
financial reporting under generally accepted accounting principles.
However, sometimes these principles, such as FAS 71, require special
accounting treatment for regulated companies to show the effect of
regulation.  For example, in setting TEP's retail rates, the ACC may not
currently allow TEP to charge its customers to recover certain expenses
but, instead, require that these expenses be charged to customers in the
future.  In this situation, FAS 71 requires that TEP not show these
expenses on its current income statements but "defer" these items and show
them as "regulatory assets" on the balance sheet until TEP is allowed to
charge its customers.  TEP then amortizes these items to the income
statement as charges are billed to customers.  Similarly, certain items of
revenue may be deferred as regulatory liabilities, which are also eventually
amortized to the income statement.

     We have recorded regulatory assets and liabilities in our balance
sheets in accordance with FAS 71.  A regulated company must satisfy certain
conditions to apply the accounting policies and practices of FAS 71. These
conditions include:

  -   an independent regulator sets rates;
  -   the regulator sets the rates to cover specific costs of delivering
      service; and
  -   the service territory lacks competitive pressures to reduce rates
      below the rates set by the regulators.

We periodically assess whether we continue to meet these conditions.  If we
were required to stop applying FAS 71 to all or a portion of TEP's
regulated utility operations, we would write off the related balances of
TEP's regulatory assets and liabilities as a charge in our income
statement.  In that event, our earnings would be reduced by the net amount
of regulatory assets and liabilities, after applicable deferred income
taxes.  Based on the balances of TEP's regulatory assets and liabilities at
June 30, 1998, if we ceased to apply FAS 71 to all of TEP's regulated
operations, we would record an extraordinary loss of approximately $152
million, net of the related deferred income tax benefit of $103 million.
While our cash flows may be affected by regulatory orders and market
conditions, our cash flows would not be affected if we ceased to apply FAS
71.

     If we cease to apply FAS 71, we would need to evaluate the likelihood
that we could recover the cost of TEP's electric plant in the marketplace
using the criteria in FAS 121.  If undiscounted cash flows are less than
the carrying value of those assets, then we would need to write-off as an
expense a portion of those plant assets to reflect their current market
value.  We cannot predict if we would write-off any plant assets as a
result of applying FAS 121.

     Legislative and other regulatory measures are being developed in
various states to deregulate the electric generation business.  The SEC and
the EITF have been reviewing whether electric utilities should stop
applying FAS 71 to the business transactions in states where deregulation
is occurring.  In general, the EITF consensus states that utilities must
cease to account for the electric generation portion of their business
under FAS 71 when a deregulation plan is in place and its terms are known.
The EITF also concluded that utilities do not need to write off regulatory
assets (including those related to generation) if the cash flow stream from
regulated rates includes recovery of the regulatory assets. We are
uncertain how the EITF consensus will impact TEP as deregulation activities
develop in Arizona.  In the future, we may need to stop applying FAS 71 to
the electric generation portion of TEP's business, even if we believe that
we will recover the full amount of our costs under the ACC competition
phase-in plan.  Approximately 55% of TEP's net regulatory assets on the
balance sheet relate to electric generation.

     On June 22, 1998, the ACC adopted an order which outlines its policy
for stranded cost recovery by Arizona utilities in a competitive energy
market.  On August 5, 1998, the ACC adopted amendments to the Retail
Electric Competition Rules which, in part, provide a two-year phase-in
schedule in which all retail customers will have access to competitive
generation by January 1, 2001.  See Competition, Retail for a discussion of
the ACC order regarding stranded cost recovery and the ACC competition
rules.

     TEP will cease to account for its generation operations using FAS 71
at the time the ACC approves a cost recovery plan specific to TEP,
including the specific amount of stranded costs that TEP can recover and a
cost recovery method.  The amount and method of recovery that the ACC
approves for TEP will determine whether write-offs will be incurred at that
time.  The ACC is not expected to approve a final stranded cost recovery 
plan for TEP until at least the fourth quarter of 1998.  We are unable to
predict the amount of write-offs, if any, that may be incurred at that
time.

     In May 1998, the Arizona Legislature passed and the Governor signed a
bill regarding retail electric competition in Arizona.  See Competition,
Retail for a discussion of legislative initiatives on retail competition.


INVESTMENTS IN ENERGY-RELATED AFFILIATES
- ----------------------------------------

      MEH Corporation (MEH), a wholly-owned subsidiary of UniSource Energy,
owns 100% of the stock of four subsidiaries.  We established these
subsidiaries to pursue various unregulated energy-related investment
opportunities:

  -  Nations Energy Corporation (Nations Energy) develops independent power
     projects worldwide.

  -  Millennium Energy Holdings, Inc. (Millennium) holds a 50% interest in
     New Energy Ventures, L.L.C. (NEV).  NEV, a buyer's agent, provides
     electric load aggregation and advisory services to retail purchasers
     of electric energy.  As of June 30, 1998, NEV had contracts to
     purchase energy for and sell energy to customers principally in
     California and New York with a combined electrical demand of more that
     1,500 MW.  NEV began serving its California customers on March 31,
     1998 when the California retail electricity market opened to
     competition.

  -  Advanced Energy Technologies, Inc. (AET) holds a 50% interest in
     Global Solar Energy, L.L.C. (Global Solar), a manufacturer of thin-
     film photovoltaic cells.

  -  Southwest Energy Solutions, Inc. (SES) provides ancillary energy
     services to electric consumers.  SES owns 100% of the stock of SWPP
     Investment Company (SWPP) and SWPP International, Ltd. (SWPPI), which
     hold ownership interests in businesses engaged in the manufacture and
     sale of concrete power poles.

      Our investments in the energy-related ventures described above
(included in Investments and Other Property in UniSource Energy's
consolidated balance sheet) comprise less than 1% of total assets.
However, the net loss related to these start-up operations totaled $5.6
million for the second quarter and $9.7 million for the first six months of
1998.  This loss is included in the Other Income (Deductions) section on
UniSource Energy's income statement.  Almost all of MEH's losses in both
the second quarter and first six months of 1998 occurred at NEV.  The
California electricity market was originally scheduled to open to
competitors such as NEV on January 1, 1998.  However, technical matters
related to the California Independent System Operator and the California
Power Exchange delayed the opening of the electricity market until March
31, 1998.  Therefore, NEV could not make retail power sales in California
in the first quarter.  Start-up costs associated with expansion into
additional regions of the country also contributed to the losses in the
first half of 1998.  Although the delays in establishment of the
competitive market caused losses at NEV in the first six months, NEV
expects losses to decline as more customers are added throughout the year.

      From September 1997, the inception of Millennium's ownership 
in NEV, through June 30, 1998, Millennium recorded approximately $23.8 
million of NEV losses.  The amount equals the total funds and commitments 
provided by Millennium and UniSource Energy to NEV.  Accounting principles 
limit the amount of the loss to be recorded by Millennium to the total 
amount invested and committed by Millennium and UniSource Energy.  Under 
its current obligations, NEV is expected to continue to incur losses and
require additional funds to fulfill its obligations.  Should Millennium or
UniSource Energy provide additional funding to NEV, the amounts provided
would need to be immediately expensed if NEV has incurred losses in excess
of $23.8 million since September 1997.  NEV is seeking sources other than
Millennium and UniSource Energy to provide necessary funding.  There can be
no assurance that any such financing will be obtained.

      Depending on the nature of future investment opportunities, we expect
to make additional investments in energy-related ventures. The ACC Holding
Company Order requires that the capitalization (debt and equity) of the
Company's affiliates other than TEP not exceed 30% of TEP's capitalization
unless otherwise approved by the ACC.

DIVIDENDS ON COMMON STOCK
- -------------------------

    UniSource Energy

      UniSource Energy's ability to pay dividends depends upon cash flow
from TEP and MEH.  As described below, TEP has called for the redemption of
those First Mortgage Bonds which have covenants restricting the payment of
dividends.  TEP has not declared or paid a dividend on common stock since
1989.  Until TEP is able to pay dividends to UniSource Energy, UniSource
Energy will probably be unable to declare or pay dividends on its Common
Stock.

    TEP

      On August 4, 1998, TEP called for the redemption on September 3, 1998
of the five outstanding issues of First Mortgage Bonds (aggregating $137
million in principal amount) which prevent TEP from paying dividends unless
specific cash flow coverage and retained earnings tests are met.  As of
June 30, 1998, TEP met the cash flow coverage test, but did not meet the
retained earnings test, which requires positive retained earnings.  These
covenants will apply until these First Mortgage Bonds have been redeemed.
See Financing Developments, TEP First Mortgage Bonds, below.

      TEP's Credit Agreement allows TEP to pay dividends if it maintains
compliance with the agreement and meets certain financial covenants,
including a covenant that requires TEP to maintain a minimum level of net
worth.  As of June 30, 1998, the required minimum net worth was $169
million.  TEP's actual net worth at June 30, 1998 was $223.7 million.  See
Financing Developments, TEP Credit Agreement, below.  As of June 30, 1998,
TEP is in compliance with the terms of the Credit Agreement.

      The ACC Holding Company Order states that TEP may not pay dividends
to UniSource Energy in excess of 75% of its earnings until TEP's equity
ratio equals 37.5% of total capital (excluding capital lease obligations).
As of June 30, 1998, TEP's equity ratio on that basis was 15.6%.

      In addition to these restrictive covenants, the Federal Power Act
states that dividends shall not be paid out of funds properly included in
the capital account.  Although the terms of the Federal Power Act
provisions are unclear, we believe that there is a reasonable basis to pay
dividends from current year earnings.   We are continuing to evaluate this
situation.

EARNINGS
- --------

     UniSource Energy recorded net income of $1.1 million in the second
quarter of 1998 compared with net income of $29.9 million in the second
quarter of 1997.  Net income per average share of Common Stock was $0.03
for the second quarter of 1998 compared with net income per average share
of Common Stock of $0.93 for the second quarter of 1997.  Net income would
have been $10.4 million or $0.32 per share in the second quarter of 1997 if
the recognition of tax benefits and other one-time adjustments had been
excluded.  The major reasons for the variance between the results for the
second quarter of 1998 and the adjusted results for the second quarter of
1997 were:

  -  higher losses from investments in unregulated energy-related
     businesses,
  -  lower retail sales due to mild weather conditions,
  -  lower non-cash regulatory revenues, and
  -  higher interest expense.

     For the first six months of 1998, the Company recorded a net loss of
$6.0 million, compared with net income of $41.4 million for the first six
months of 1997.  The net loss per average share of Common Stock was $0.19
for the first six months of 1998 compared with net income per average share
of Common Stock of $1.29 for the first six months of 1997.  We would have
recorded net income of $10.0 million or $0.31 per share in the first six
months of 1997 excluding the recognition of tax benefits and other one-time
adjustments.  The major reasons for the variance between the results for
the first half of 1998 and the adjusted results for the first half of 1997
were the same factors that impacted the second quarter as described above.

     TEP recorded net income of $8.1 million for the second quarter of
1998, compared with net income of $29.9 million in the second quarter of
1997.  The second quarter earnings decrease was primarily attributable to
lower tax benefit recognition, nonrecurring items, lower retail sales due
to mild weather conditions, lower non-cash regulatory revenues and higher
interest expense from refinancings.  Earnings for the six-months ended June
30, 1998 were $6.5 million, compared with net income of $41.4 million for
the same period in 1997.  Earnings for the six-month period were affected
by the same factors as discussed above for the second quarter.

RESULTS OF OPERATIONS
- ---------------------

     Currently, TEP's financial condition and results of operations are the
primary factors affecting the financial condition and results of operations
of UniSource Energy on an annual basis.  We note any fluctuations that are
not primarily due to TEP activities.  All nonutility operating transactions
are reflected in Other Income (Deductions) on the UniSource Energy
Consolidated Statement of Income.

</TABLE>

     TEP's kWh sales to retail customers decreased by 3.6% during the
second quarter of 1998 compared with the second quarter of 1997.  Although
TEP experienced retail customer growth of 1.8%, moderate weather conditions
in the quarter contributed to the decline in retail kWh sales.  Based on
cooling degree days, a commonly used measure in the electric industry that
is calculated by subtracting 75 from the average of the high and low daily
temperatures, the Tucson area registered a decrease of approximately 36% in
cooling degree days for the second quarter of 1998 compared with the same
period in 1997, and a decrease of approximately 41% in cooling degree days
compared with the ten year average for the same period from 1988 to 1997.
Cooling degree days for the second quarter of 1998 were 256, compared to
402 for the second quarter of 1997 and 435 for the ten-year average.

     For the first six months of 1998, kWh sales to retail customers were
2.9% higher than the same period in 1997.  Although the weather was milder
in the second quarter, which reduced retail electric usage, the weather in
the first quarter was cooler than in 1997, which increased the electric
heating load for that quarter.  KWh sales to the Company's mining customers
also increased for the six-month period of 1998 due to contract amendments
that went into effect in mid-1997.

     Revenues from sales to retail customers decreased by 5.3% in the
second quarter of 1998 compared to the same period in 1997 because of the
lower kWh sales.  This decrease in retail revenues is slightly larger than
the decrease in kWh sales as a result of new long-term contracts with large
commercial, industrial and mining customers.  These contracts went into
effect after the first quarter of 1997 and have lower rates than the prior
contracts.  Retail revenues for the six-month period of 1998 were
relatively flat, with the increase in kWh sales noted above offset by the
impacts of lower rates under long-term contracts to large customers.

     The lower retail demand in the second quarter allowed TEP to increase
its wholesale sales activity.  Our kWh sales for resale increased by 38.4%
and the related revenues grew by 40.3% in the second quarter of 1998
relative to the same period in 1997.  For the six months ending June 30,
1998, sales for resale were up 28.9% and wholesale revenues increased 29.6%
compared to the same period in 1997.

     Retail electric sales rebounded in late June and in July 1998, as a
result of higher summer temperatures and increased humidity in TEP's retail
service territory.  On July 16, 1998, TEP set a record for retail
electricity sold in a 24-hour period, distributing 33,959 megawatt-hours to
its retail customers, a 7.0% increase over the previous record set in 1997.
In addition, on July 16, 1998, TEP experienced a new record peak demand of
1,786 MW, an increase of 7.7% over the previous record of 1,659 MW set on
August 10, 1997.

     TEP's non-cash revenue from the Amortization of the MSR Option Gain
Regulatory Liability was $3.1 million lower in the second quarter and $8.1
million lower in the first half of 1998 compared to the same periods in
1997.  This regulatory liability was fully amortized in May 1997.  If we
exclude the revenue from the MSR Option Gain amortization, total operating
revenues were unchanged in the second quarter and 3.5% higher in the first
half of 1998 than the same periods in 1997.

  Operating Expenses

     Fuel and Purchased Power expense increased by 10% in the second
quarter and 8% in the first half of 1998 compared with the same period in
1997 because of the increased purchased power to support the higher
wholesale sales we discussed above.     If we exclude the growth in Fuel
and Purchased Power expense, other operating expenses decreased in total by
5% in the second quarter and by 2% in the first half of 1998 over the same
periods in 1997.

     Maintenance and Repairs expense was lower in both the second quarter
and first half of 1998 than in the same periods of 1997.  Maintenance
expense was higher for those periods in 1997 due to scheduled maintenance
work at the Springerville station.

 Other Income (Deductions)

     UniSource Energy and TEP recognized $15 million of NOL benefit in the
second quarter of 1997 and none in 1998. This reduced benefit recognition,
offset by lower tax expense resulting from decreased income, caused the
second quarter 1998 income tax benefits included in Other Income
(Deductions) to decrease by $4.7 million and $9.3 million for UniSource
Energy and TEP, respectively, from the second quarter of 1997.

     Compared with the first six months of 1997, 1998 income tax benefits
included in Other Income (Deductions) decreased by $17.0 million and $25.4
million for UniSource Energy and TEP, respectively.  These changes are
mainly due to lower recognition of Net Operating Loss (NOL) benefits offset
by greater tax benefits as a result of lower income.  UniSource Energy and
TEP recognized $29.3 million of NOL benefit in the first six months of 1997
and none in 1998.

     As of December 31, 1997, both UniSource Energy and TEP had recorded
the amount of prior period NOL benefit that we expect to use on future
income tax returns.  At the present time, we are not able to estimate
future additional amounts of NOL benefit that we may recognize in the
income statements of either UniSource Energy or TEP.  This is because there
are still open tax years for which there may be additional assessments and
because federal and state NOL carryforwards have varying expiration dates.
We do not expect to recognize additional amounts of NOL benefit until such
items are resolved.

     A Reversal of Loss Provision of $10.2 million was recorded in the
second quarter of 1997.  The Reversal of Loss Provision relates to the
dissolution of a subsidiary which formed part of TEP's former investment
operations.

     Other Income for TEP includes interest income on the promissory note
it received from the Company in exchange for the transfer of its stock in
MEH.  See Note 3 of Notes to the Condensed Consolidated Financial
Statement--Transfer of MEH from TEP to UniSource Energy.  TEP recorded
interest income of $2.3 million in the second quarter and $4.6 million in
the first half of 1998 from this note.  On the Consolidated Statement of
Income for the Company, this income is eliminated as an inter-company
transaction.

     The unregulated energy subsidiaries owned by MEH reported a net loss
of $5.6 million for the second quarter and $9.7 million for the first half
of 1998, compared with net income of $0.5 million in the second quarter and
a net loss of $0.4 million for the first half of 1997.  The delayed
implementation of California's competitive electricity market until March
31, 1998, expansion into additional regions of the country, and other
subsidiary development activities affected the financial results for these
businesses.  See Investments in Energy-Related Affiliates.

  Interest Expense

     Interest expense increased by $3.4 million in the second quarter and
by $7.6 million of the first six months of 1998 relative to the same
periods in 1997.  Higher letter of credit fees for TEP's new Credit
Agreement, as well as higher interest rates from the refinancing of certain
variable rate debt obligations with fixed rate debt obligations accounted
for the increase.  (See Financing Developments, TEP Sale of Bonds, below).
These refinancings benefit TEP by extending debt maturities and reducing
the risk from changes in variable interest rates.

 EVENTS AFFECTING FUTURE RESULTS OF UTILITY OPERATIONS

  TEP Generating Resources

     On May 1, 1998, the lease on three internal combustion turbine
generating units having a combined generating capacity of 96 MW ended.  TEP
is in the process of evaluating the need for this type of peaking
generation resource in the near term.  Firm capacity purchases needed to
replace the expired leased capacity are not expected to have a material
negative impact on UniSource Energy or TEP financial results.

LIQUIDITY AND CAPITAL RESOURCES
- -------------------------------

  CASH FLOWS

     UniSource Energy

     Cash and cash equivalents increased by $43.9 million, or 50% during
the twelve months ended June 30, 1998.  The June 30, 1998 ending balance
was $132.1 million compared with the June 30, 1997 ending balance of $88.2
million.  For the twelve-month period ended June 30, 1998, net cash flows
from operating activities exceeded the cash needed for investing and
financing activities.

     Net cash flows from operating activities increased in aggregate by
$27.5 million in the first six months of 1998 compared with the same period
in 1997.  This increase was mainly due to the payment of $30 million in
contract termination fees to the Springerville coal supplier in the first
half of 1997 compared to $10.0 million paid to the coal supplier in the
first half of 1998 (see Note 6 of Notes to Condensed Consolidated Financial
Statements--Rate Matters).  In addition to the contract termination fees,
we received $11.3 million in June 1998 from the sale of emission
allowances.

     Total net cash outflows from investing activities increased by $12.5
million during the first half of 1998 compared with the same period in
1997.  An $8.9 million increase in Investments in Joint Ventures and a $4.4
million increase in Construction Expenditures were the primary reasons for
this change.

     Total net cash outflows from financing activities decreased by $13.0
million in the first half of 1998 compared with the same period in 1997.
Net retirements of long-term debt and capital lease obligations were
greater in the first half of 1997, primarily due to the repayment of the
$31 million balance outstanding on TEP's Renewable Term Loan.

     Our consolidated cash balance, including cash equivalents, at August
7, 1998 was approximately $132 million.  Of this amount, $102 million was
held by TEP and its wholly-owned subsidiaries.  These amounts exclude the
proceeds from the sale of TEP's First Collateral Trust Bonds on August 4,
1998, which will be used for the redemption of five series of First
Mortgage Bonds on September 3, 1998 (see Financing Developments, TEP First
Mortgage Bonds, below).  We invest cash balances in high-grade money market
securities with an emphasis on preserving the principal amounts invested.

     During 1998 and beyond, our sources of cash will be primarily
dividends from TEP (when allowed) and proceeds from sales of securities.
Potential cash needs may include funds for subsidiaries, funds to meet debt
obligations and funds to pay dividends to shareholders.  See Dividends on
Common Stock and Financing Developments, UniSource Energy for details on
these sources and uses of funds.

     TEP

     Cash and cash equivalents increased by $15.0 million, or 17%, from the
June 30, 1997 ending balance of $88.2 million to the June 30, 1998 ending
balance of $103.2 million.    TEP expects to generate enough cash flow
during 1998 to fund continuing operating activities and construction
expenditures.  Actual cash flows may vary from projections if there are
changes in wholesale revenues, changes in short-term interest rates or
other factors.  If cash flows were to fall short of our expectations, TEP
would use existing cash balances and, if necessary, borrow from the
Revolving Credit Facility.  At August 7, 1998, there was no outstanding
balance due under the Revolving Credit Facility.

  FINANCING DEVELOPMENTS

    TEP Sale of Bonds

     On March 17, 1998, the Apache County, Arizona Industrial Development
Authority issued $200 million of new bonds for the benefit of TEP.   The
proceeds were used on May 15, 1998 to redeem the 1981 Series A Apache
County Pollution Control Revenue Bonds due 2020 ($100 million) and the 1981
Series B Apache County Pollution Control Revenue Bonds due 2021 ($100
million).  The new bonds, which are unsecured, were issued in three series:
Series A Pollution Control Revenue Bonds ($83.7 million) bears interest at
5.85% and matures in 2028; Series B Pollution Control Revenue Bonds ($99.8
million) bears interest at 5.875% and matures in 2033; and Series C
Industrial Development Revenue Bonds ($16.5 million) bears interest at
5.85% and matures in 2026.

     The 1981 Series A Apache Bonds were supported by a letter of credit.
This LOC was collateralized by Second Mortgage Bonds under the terms of
TEP's Credit Agreement.  When TEP redeemed these bonds, the Letter of
Credit Facility decreased from $444 million to $341 million and the Second
Mortgage Bonds collateralizing those LOCs decreased by $103 million.  The
1981 Series B Apache Bonds were supported by a letter of credit outside of
the Credit Agreement.  This LOC was collateralized by First Mortgage Bonds.
When TEP redeemed these bonds, it eliminated the supporting LOC and retired
$103 million of First Mortgage Bonds collateralizing the LOC.

    TEP Credit Agreement

     As of June 30, 1998 and as of August 7, 1998, TEP had no borrowings
outstanding under its $100 million Revolving Credit Facility.

     As described above in TEP Sale of Bonds, after TEP redeemed the 1981
Series A Apache County Pollution Control Revenue Bonds on May 15, 1998, the
amount of its Letter of Credit Facility decreased to $341 million and the
amount of its total facilities under the Credit Agreement, which includes
the Revolving Credit Facility discussed above, decreased to $441 million.

     TEP is required by its Credit Agreement to maintain certain financial
covenants including (a) a minimum Consolidated Tangible Net Worth equal to
the sum of $133 million plus 40% of cumulative Consolidated Net Income
since January 1, 1997, (b) a minimum Cash Coverage Ratio ranging from 1.30
in 1998 and gradually increasing to 1.55 in 2002, and (c) a maximum
Leverage Ratio ranging from 7.00 in 1998 and gradually decreasing to 6.20
in 2002.  For the quarter ended June 30, 1998, TEP was in compliance with
each of these covenants.

    TEP First Mortgage Bonds

     In 1997 the ACC granted authority to TEP to refinance up to $184
million of its First Mortgage Bonds scheduled to mature between 1999 and
2003, as well as any redemption premiums, by issuing new debt and/or equity
securities.  As described below, TEP plans to complete these transactions
by the end of the third quarter 1998.  TEP's objective is to extend
maturities and eliminate certain restrictive covenants contained in the
existing First Mortgage Bonds.

     On May 15, 1998, TEP exchanged $46.9 million of its existing 12.22%
First Mortgage Bonds due 2000 for an identical amount of new 12.22%
Exchange Series First Mortgage Bonds due 2000.  With the exception of the
elimination of a covenant restricting the payment of dividends, the new
bonds have substantially the same terms and conditions as the existing
bonds.

     On August 4, 1998, TEP issued $140 million of First Collateral Trust
Bonds, Series A, and will use the proceeds on September 3, 1998 to redeem
all of its First Mortgage Bonds due in 1999, 2001, 2002, and 2003, as well
as the $31.9 million of 12.22% First Mortgage Bonds due 2000 not tendered
for exchange as described above.  The bonds to be redeemed bear interest at
rates ranging from 7.55% to 12.22%.  When TEP redeems the bonds as
described above, TEP will have eliminated covenants that currently prohibit
it from paying common stock dividends so long as it has an accumulated
earnings deficit (see Dividends on Common Stock).  The First Collateral
Trust Bonds, Series A bear interest at 7.50% and mature in 2008.  The First
Collateral Trust Bonds are not secured by a direct mortgage or other lien
on property of TEP, but instead are collateralized by an equal aggregate
principal amount of bonds issued under TEP's General First Mortgage and
held by the trustee.  If and when the bonds collateralizing the First
Collateral Trust bonds constitute all bonds outstanding under TEP's General
First Mortgage, the bonds issued under the General First Mortgage may be
surrendered and substituted with an equal amount of bonds issued under the
General Second Mortgage.  If and when the bonds collateralizing the First
Collateral Trust bonds constitute all bonds outstanding under the General
Second Mortgage, the bonds may be surrendered and the First Collateral
Trust Bonds, Series A will become unsecured obligations of TEP.

    UniSource Energy--Loans and Guarantees

     In December 1997, Millennium committed to provide NEV with $20 million
of funding.  At July 31, 1998, NEV had received the following under the $20
million commitment:

  -  Millennium provided $10 million in loans to NEV.
  -  Millennium provided $4 million for NEV preferred equity.
  -  UniSource Energy issued guarantees in the aggregate amount of $5.5
     million to secure the obligations of NEV to counterparties to energy
     purchase and sale agreements.

As a result of these loans and guarantees, the remaining commitment amount
available was $0.5 million at July 31, 1998.

     UniSource Energy is the guarantor of $32.8 million of performance
bonds that secure the amounts NEV California owes to the California utility
distribution companies (UDCs) for services provided by the UDCs in
connection with NEV California's sales in the California retail electric
market.  NEV California bills its customers for these UDC charges.

     In August 1998, UniSource Energy agreed to guarantee a $10 million 
loan that NEV obtained from an unrelated party.  The debt underlying the 
guarantee is not due until 1999. 


IMPACT OF YEAR 2000 ON COMPUTER SYSTEMS AND APPLICATIONS
- --------------------------------------------------------

      The Company continues to review, test and make modifications to its
computer systems and applications in an effort to ensure that its
generation, transmission and distribution facilities will provide
uninterrupted service and that year 2000 transactions can be processed.
The Company's year 2000 program commenced in 1996.

      We have completed an inventory and assessment for each of our critical
enterprise information systems.  The remediation of these systems began in
1996 and is expected to be completed by the end of 1998, including testing 
and implementation.

      We are reviewing the control and embedded systems of TEP's utility
plant (including the units that TEP owns part of but does not operate), as
well as whether major vendors are addressing the problem.  We anticipate
the inventory and assessment stages of the control and embedded systems
program to be substantially completed in the third quarter of 1998.  We 
expect remediation efforts to begin in the third quarter of 1998 and to 
be substantially completed by the end of the second quarter of 1999.  
The Company intends to begin contingency planning to attempt to address 
the possibility that not all remediation efforts will succeed.

      The Company has also identified the major vendors from whom we
purchase products or services.  We are contacting those vendors to
determine their plans to correct any problems they may face with year 2000
compliance and investigate any potential impact on TEP.  TEP and other
electric service providers in the WSCC are evaluating potential year 2000
risks resulting from interconnected electric and informational systems.
Such interconnected systems are critical to the reliability and integrity
of each interconnected electric service provider.  It is possible that the
failure of one such interconnected provider to achieve year 2000 compliance
could disrupt the provision of electric services by others.  TEP and other
providers in the WSCC are working together in an effort to avoid such
disruptions.

      From 1996 through June 30, 1998, year 2000 project costs of
approximately $600,000 have been incurred, all of which were expensed.  A
budget of $1.35 million has been established for year 2000 project costs.
All 2000 remediation costs will be expensed as incurred. 
 
      At this time we believe that all identified modifications to systems 
which the Company operates will be made within the required time frames.
Notwithstanding the Company's efforts, there can be no assurance that all
year 2000 problems with systems the Company operates will be identified and
remediated in a timely fashion.  Although the Company believes that, as a
result of its year 2000 program, any problems arising from the failure to
achieve year 2000 compliance will be minor, it is possible that non-
compliance could disrupt the generation, transmission or distribution of
electric energy.  We cannot assure the year 2000 compliance status of 
systems or parties that the Company does not control.   We cannot assess
the effect on the Company of non-compliance by systems or parties that 
the Company does not control.

SAFE HARBOR FOR FORWARD-LOOKING STATEMENTS
- ------------------------------------------

      This Quarterly Report on Form 10-Q contains forward-looking
statements as defined by the Private Securities Litigation Reform Act of
1995.  UniSource Energy and TEP include the following cautionary statements
to take advantage of the safe harbor provisions of the Private Securities
Litigation Reform Act of 1995 for any forward-looking statements made by,
or for, UniSource Energy or TEP in this Quarterly Report on Form 10-Q.
Forward-looking statements include statements concerning plans, objectives,
goals, strategies, future events or performance and underlying assumptions.
They include statements which are not statements of historical fact.  Such
forward-looking statements may be identified by the use of words such as
"anticipates," "estimates," "expects," "intends," "plans," "predicts,"
"projects," and similar expressions. UniSource Energy and TEP may
occasionally publish or make available forward-looking statements of this
nature. These cautionary statements and any other cautionary statements
which may accompany the forward-looking statements expressly qualify all
such forward-looking statements, whether written or oral, and whether made
by or for UniSource Energy or TEP.  In addition, UniSource Energy and TEP
disclaim any obligation to update any forward-looking statements to reflect
events or circumstances after the date we make forward-looking statements.

      Forward-looking statements involve risks and uncertainties which
could cause actual results or outcomes to differ materially from those we
express in the forward-looking statements.  We express in good faith the
expectations, beliefs and projections contained in this document.   We
believe we have a reasonable basis to make such statements based on our
examination of historical operating trends, data contained in our records
and other data available from third parties.  However, we cannot assure
that we will achieve our expectations, beliefs or projections.  In addition
to other factors and matters discussed in this document, we believe some of
the important factors that could cause actual results to differ materially
from those we discuss in the forward-looking statements include the
following:

1. Effects of restructuring initiatives in the electric industry and other
   energy-related industries.

2. Changes in economic conditions, demographic patterns and weather
   conditions in TEP's retail service area.

3. Changes affecting TEP's cost of providing electrical service including
   changes in fuel costs, generating unit operating performance, interest
   rates, tax laws, environmental laws, and the general rate of inflation.

4. Changes in governmental policies and regulatory actions with respect to
   allowed rates of return, financings, rate structures, and methods of
   establishing rates.

5. Changes affecting the cost of competing energy alternatives, including
   changes in available generating technologies and changes in the cost of
   natural gas.

6. Changes in accounting principles or the application of such principles
   to UniSource Energy, TEP, or any subsidiary.

SHAREHOLDER PROPOSAL DEADLINE FOR 1999 ANNUAL MEETING

     Rule 14a-4 of the Securities and Exchange Commission's proxy rules
allows the Company to use discretionary voting authority to vote on a
matter coming before an annual meeting of the shareholders which are not
included in the Company's proxy statement, if the Company does not have
notice of the matter at least 45 days before the date on which the Company
first mailed its proxy materials for the prior year's annual meeting of the
shareholders.  In addition, discretionary voting authority may generally
also be used if the Company receives timely notice of such matter (as
described in the preceding sentence) and if, in the proxy statement, the
Company describes the nature of such matter and how the Company intends to
exercise its discretion to vote on such matter.  Accordingly, for the 1999
Annual Meeting of the Company, any such notice must be submitted to the
Secretary of the Company on or before February 13, 1999.

     This requirement is separate and apart from the Securities and
Exchange Commission's requirements that a shareholder must meet in order to
have a shareholder proposal included in the Company's proxy statement.
Shareholder proposals intended to be presented at the 1999 Annual Meeting
of the Company must be received by the Company no later than December 2,
1998 in order to be eligible for inclusion in the Company's proxy statement
and the form of proxy relating to that meeting.

the reversion and reversions, remainder and remainders, and all the estate,
right, title and interest and claim whatsoever, at law as well as in equity,
which the Company now has or may hereafter acquire in and to the aforesaid
premises, property, assets, rights and franchises and every part and parcel
thereof.

      And the Company, for itself and its successors, does hereby covenant
and agree to and with the Trustee and its successors in the trust under the
Indenture, for the benefit of those who shall hold the bonds and coupons, or
any of them, to be issued hereunder and thereunder, as follows:

                                  ARTICLE I.

        CREATION AND DESCRIPTION OF BONDS OF THE 2000 EXCHANGE SERIES.

      SECTION 1. A new series of bonds to be issued under and secured by the
Indenture is hereby created, to be designated as First Mortgage Bonds,
12.22% Exchange Series due 2000.  The Bonds of the 2000 Exchange Series
shall be limited to an aggregate principal amount of _____________________
Dollars ($____________), excluding any Bonds of the 2000 Exchange Series
which may be authenticated in exchange for or in lieu of or in substitution
for or on transfer of other Bonds of the 2000 Exchange Series pursuant to
any provisions of the Original Indenture or of this Supplemental Indenture.
Said Bonds shall be substantially in the form set forth in Exhibit A to this
Supplemental Indenture.

      All Bonds of the 2000 Exchange Series shall mature June 1, 2000 and
shall bear interest at the rate of 12.22% per annum, payable semi-annually
on June 1 and December 1 in each year, the beginning of the first interest
period being December 1, 1997 and the first interest payment date being June
1, 1998; and the principal of, and the interest, and premium, if any, on,
the Bonds shall be payable at the office or agency of the Company in the
Borough of Manhattan, The City of New York, or in the City of Tucson in coin
or currency of the United States of America which at the time of payment
shall be legal tender for the payment of public and private debts; provided
that a holder of a Bond may elect to receive payments of the principal of,
and the interest, and premium, if any, on such Bond (other than at maturity
or upon redemption of the Bonds as a whole) by wire transfer of immediately
available funds to an account maintained by such holder at a bank located in
the United States of America if appropriate wire transfer instructions are
received by such office or agency not less than 15 calendar days prior to
the date for payment.

      The holder of any Bond on any record date (as hereinbelow defined)
with respect to any interest payment date shall be entitled to receive the
interest payable on such interest payment date notwithstanding the
cancellation of such Bond upon any exchange or transfer thereof subsequent
to the record date and prior to such interest payment date, except if and to
the extent the Company shall default in the payment of the interest due on
such interest payment date, in which case such defaulted interest shall be
paid to the person in whose name such Bond (or any Bond or Bonds issued upon
transfer or exchange thereof) is registered on the date of payment of such
defaulted interest.  The term "record date" as used in this Section with
respect to any interest payment date shall mean the May 15 or November 15,
as the case may be, next preceding such interest payment date, or, if such
May 15 or November 15 shall be a legal holiday or a day on which banking
institutions in The City of New York are authorized by law to remain closed,
the next preceding day which shall not be a legal holiday or a day on which
such institutions are so authorized to remain closed; provided, however,
that, with respect to the interest payment date of June 1, 1998, the record
date shall be the date of the initial authentication and delivery of the
Bonds of the 2000 Exchange Series.

      Each Bond shall be dated as provided in Section 4 of Article II of the
Original Indenture, except that, if there is no existing default in the
payment of interest on the Bonds, each Bond authenticated by or on behalf of
the Trustee between the record date with respect to any interest payment
date and such interest payment date shall be dated as of such interest
payment date.

      The Company shall not be required to make any transfer or exchange of
any Bonds for a period of 10 days next preceding any selection of Bonds for
redemption, nor shall it be required to make transfers or exchanges of any
Bonds which shall have been designated for redemption in whole or in part.

      The Bonds of the 2000 Exchange Series shall be issued in fully
registered form only, in denominations of $1,000 and multiplies thereof.

      The Bonds of the 2000 Exchange Series shall be registrable and
exchangeable at the office or agency of the Company in the Borough of
Manhattan, The City of New York in the manner and upon the terms set forth
in Section 5 of Article II of the Original Indenture, without payment of any
charge other than a sum sufficient to reimburse the Company for any stamp
tax or other governmental charge incident thereto.

      SECTION 2. The Trustee agrees that if any mutilated, lost, stolen or
destroyed Bonds of the 2000 Exchange Series was held by an original holder
or other institutional holder (a) an agreement of indemnity satisfactory to
the Company from such original holder or such other institutional holder
shall constitute "indemnity in a sum deemed satisfactory" by the Trustee for
purposes of Section 11 of Article II of the Indenture and (b) the Trustee
will look only to the Company for reimbursement of its expenses incurred in
connection with such replacement.

      SECTION 3. The Bonds of the 2000 Exchange Series may be executed by
the Company and delivered to the Trustee and, upon compliance with all
applicable provisions and requirements of the Original Indenture in respect
thereof, shall be authenticated by the Trustee and delivered (without
awaiting the filing or recording of the Supplemental Indenture) in
accordance with the written order or orders of the Company.

                                 ARTICLE II.

                    REDEMPTION OF AND PAYMENTS DUE UPON
           ACCELERATION OF THE BONDS OF THE 2000 EXCHANGE SERIES.

      SECTION 1. The Bonds of the 2000 Exchange Series are redeemable prior
to maturity at the option of the Company, as a whole at any time, or in part
from time to time in a minimum aggregate principal amount at any one time of
not less than $20,000,000, provided, that no less than $20,000,000 in
aggregate principal amount of the Bonds of the 2000 Exchange Series remains
outstanding after giving effect to any such partial redemption, upon at
least 30 days' prior notice, all as provided in the Indenture, at the
principal amount of Bonds so to be redeemed and accrued interest to the date
fixed for redemption, together with an amount equal to the Make-Whole
Premium, provided, that the Company shall, on the date of any such
redemption, deliver to the Trustee and to the holders of the Bonds so to be
redeemed a certificate stating the amount of the Make-Whole Premium being
paid upon such redemption and demonstrating the calculation thereof.
Anything in the Indenture to the contrary notwithstanding and except as set
forth in the fourth succeeding paragraph, the redemption price for all
redemptions of the Bonds of the 2000 Exchange Series shall be the redemption
price set forth in the next preceding sentence, and each redemption of the
Bonds of the 2000 Exchange Series shall be pro rata among the Bonds of the
2000 Exchange Series as provided in section 3 of this Article II.

      For purposes of this Supplemental Indenture, the term "Make-Whole
Premium" shall mean with respect to any redemption or payment (whether on
account of acceleration or otherwise) of the Bonds of the 2000 Exchange
Series, (a) to the extent that the Treasury Rate at the time of such
redemption or payment is lower than 12.22% per annum, the excess of (i) the
present value of the principal and interest payments on and in respect of
the Bonds of the 2000 Exchange Series being redeemed or paid, as the case
may be, that would otherwise become due and payable (without giving effect
to such redemption or payment), discounted at a rate which is equal to the
Treasury Rate over (ii) the principal amount of the Bonds of the 2000
Exchange Series being redeemed or paid, as the case may be, and (b) to the
extent that the Treasury Rate at the time of such redemption or payment is
equal to or higher than 12.22% per annum, zero.

      For purposes of this Supplemental Indenture, the term "Treasury Rate"
shall mean at the time of any redemption or payment with respect to any
Bonds of the 2000 Exchange Series being redeemed or paid (whether on account
of acceleration or otherwise), as the case may be, the arithmetic average of
the two most recent yields to maturity on the United States Treasury
obligation with a constant maturity determined by reference to the
applicable display on the Bloomberg Financial Markets Service L.P. (or, if
such display is no longer available, any publicly available reliable source
of similar market data) for the two business days next preceding the date of
such redemption or payment) most nearly equal to (by rounding to the nearest
month) the Remaining Life to Maturity of the Bonds of the 2000 Exchange
Series then being redeemed or paid (whether on account of acceleration or
otherwise).

      For purposes of this Supplemental Indenture, the term "Remaining Life
to Maturity" of Bonds of the 2000 Exchange Series shall mean, at any date,
the number of years obtained by dividing the then Remaining Dollar-years of
such Bonds by the then outstanding principal amount of such Bonds.  For
purposes of this definition, the "Remaining Dollar-years" of any such Bonds
shall mean, at any date, the product obtained by multiplying (a) the
aggregate outstanding principal amount of such Bonds, by (b) the number of
twelve-month periods (calculated to the nearest one-twelfth) which will
elapse between such date and June 1, 2000.

      In the event that all or substantially all of the electric utility
properties of the Company at the time subject to the lien of the Indenture
shall be sold, taken by eminent domain or otherwise disposed of, as an
entirety or substantially as an entirety, and shall be released from the
lien of the Indenture, the entire award or other cash proceeds of such sale,
taking or other disposition, together with any other Available Moneys (as
defined in Section 11 of Article VII of the Original Indenture), if any,
then held by the Trustee, shall, to the extent and in the manner provided in
Section 11 of Article VII of the original Indenture, be applied to the pro
rata payment or redemption of the bonds of all series then outstanding under
the Indenture, all as more fully provided in the Original Indenture, and the
Bonds of the 2000 Exchange Series shall, in such event, become subject to
such redemption or payment.  All such redemptions of the Bonds of the 2000
Exchange Series shall be at the redemption price specified in the first
paragraph of this Section 1.

      SECTION 2. All of the provisions of Article V of the Original
Indenture, other than Sections 2 and 3 thereof and the fourth paragraph of
Section 4 thereof, shall be applicable to the redemption of Bonds of the
2000 Exchange Series; and the "Available Moneys", as defined in Section 11
of Article VII of the Original Indenture, apportioned to Bonds of the 2000
Exchange Series, shall be applied by the Trustee to the payment of the
redemption price thereof together with accrued interest to the date fixed
for such payment, or if such apportioned Available Moneys are insufficient
for such full payment, then, upon notice similar to that provided in the
fourth paragraph of said Section 11 in respect of the bonds referred to
therein, first to the payment of the unpaid interest accrued to the date
fixed for payment and the balance to the payment of the then applicable
redemption price (exclusive of such interest), to the extent that such
moneys shall suffice, pro rata, as provided in Section 11 of Article VII of
the Original Indenture, upon presentation and stamping in a manner similar
to that provided by Section 11 of Article VII of the Original Indenture for
the bonds referred to therein and the coupons appurtenant thereto, interest
to cease to accrue upon Bonds of the 2000 Exchange Series on the payment
date specified in the notice to the extent of the partial payment so
provided.  Until the full amount then due and owing on all Bonds of the 2000
Exchange Series shall have been paid, no such partial payment shall
discharge the obligation of the Company on such Bonds, except to the extent
of such partial payment; and the balance of principal, if any, remaining
after such payment shall thereafter constitute the unpaid obligation of the
Company upon the Bonds of the 2000 Exchange Series and the principal amount
of the Bonds of the 2000 Exchange Series upon which interest shall
thereafter be due and payable.

      SECTION 3. Anything contained in the fourth paragraph of Section 4 of
Article V of the Original Indenture to the contrary notwithstanding, in case
less than all of the outstanding Bonds of the 2000 Exchange Series are to be
redeemed, the principal amount to be redeemed shall be prorated among the
holders of the Bonds of the 2000 Exchange Series in the proportion that
their respective holdings bear to the aggregate principal amount of Bonds of
the 2000 Exchange Series outstanding on the date of selection.  The portion
of any Bond of the 2000 Exchange Series to be redeemed shall be in the
principal amount of $1,000 or a multiple thereof and such allocations as may
be requisite for this purpose shall be made by the Trustee in its
uncontrolled discretion.  The Trustee shall promptly notify the Company in
writing of the distinctive numbers of the Bonds of the 2000 Exchange Series
and the portions thereof so selected for redemption.

      SECTION 4. Anything in the Indenture to the contrary notwithstanding,
if the principal of all bonds outstanding under the Indenture and the
interest accrued thereon shall have become immediately due and payable
pursuant to any provision of Article VIII of the Original Indenture, the
principal of all Bonds of the 2000 Exchange Series outstanding under the
Indenture and interest accrued thereon shall, together with, to the extent
permitted by applicable law, an amount equal to the Make-Whole Premium with
respect to such Bonds of the 2000 Exchange Series, become immediately due
and payable, and the Company shall forthwith pay to the holders of the Bonds
of the 2000 Exchange Series then outstanding the entire principal of and all
interest accrued on such Bonds of the 2000 Exchange Series plus such Make-
Whole Premium; provided, that in such event the trust estate shall be
applied to the payment of such Make-Whole Premium only in accordance with
Article VIII of the Original Indenture.  The term "premium" when used in the
Bonds of the 2000 Exchange Series or the Indenture in conjunction with
references to principal of and interest on the Bonds, shall mean any amount
due upon any payment, redemption or prepayment of any of the Bonds of the
2000 Exchange Series, other than principal and interest, and shall include
the Make-Whole Premium.

      SECTION 5. The holder of each and every Bond of the 2000 Exchange
Series issued hereunder hereby agrees to accept payment thereof prior to
maturity on the terms and conditions provided for in this Article II.

                                 ARTICLE III.

                            ADDITIONAL COVENANTS.

      The Company covenants and agrees that, so long as any Bonds of the
2000 Exchange Series shall be outstanding, and unless the Company shall have
delivered to the Trustee any number of concurrent instruments of similar
tenor executed by holders of a majority or more in aggregate principal
amount of the Bonds of the 2000 Exchange Series then outstanding in which
such holders waive the same in the particular case, the Company will duly
perform and observe each and all of the covenants and agreements hereinafter
set forth in this Article III.

      SECTION 1. The Company will not declare or pay any dividends on its
shares of common stock (other than dividends payable in shares of its common
stock), or make any other distribution on its shares of common stock, or
purchase or redeem any shares of its capital stock of any class (other than
with the proceeds of additional capital stock financing and other than
mandatory sinking fund payments with respect to capital stock senior to the
common stock of the Company issued after the date hereof) if the Company's
Consolidated Net Worth as of the last day of any fiscal quarter following
the date hereof is less than (a) the sum of (i) $133,000,000, (ii) 40% of
the Company's Consolidated Net Income for each fiscal year after December
31, 1996, for which Consolidated Net Income is positive and (iii) with
respect to each of the first three fiscal quarters of a fiscal year after
the most recent fiscal year end, 40% of the Company's Consolidated Net

basis, if positive, minus (b) the least of (x) $175,000,000, (y) the
aggregate amount of non-cash charges taken by the Company after the date
hereof pursuant to the requirements of Statement of Financial Accounting
Standards No. 101 and (z) in the event that the Applicable Credit Ratings
assigned to the Company's First Mortgage Bonds shall be downgraded within 90
days after the public disclosure of any decision by the Company to apply
Statement of Financial Accounting Standards No. 101, zero.  For purposes of
this Section 1, (a) "Consolidated Net Worth" means, as of the last day of
any fiscal quarter, common stock equity of the Company as of such day, (b)
"Consolidated Net Income" means, for any fiscal period net income of the
Company and its consolidated Subsidiaries, determined on a consolidated
basis, and (c) "Applicable Credit Ratings" means (i) in the event that the
credit rating levels assigned to the Company's First Mortgage Bonds by
Moody's Investor Service, Inc. ("Moody's") and Standard & Poor's Rating
Group ("S&P") are different, the higher of such ratings, and (ii) in the
event that the credit rating levels assigned to the Company's First Mortgage
Bonds by Moody's and S&P are the same, both such ratings.  All
determinations pursuant to this Section 1 shall be made in accordance with
generally accepted accounting principles as in effect from time to time.

    SECTION 2.  The Company will not, and will not permit any Subsidiary to,
engage to any material extent in any business other than the Utility

    For purposes of this Section 2, (a) "Utility Business" means the
business of producing, developing, generating, transmitting, distributing,
selling or supplying electrical energy for any purpose, or any business
incidental thereto or necessary in connection therewith, or any business
reasonably desirable in connection therewith which the Arizona Corporation
Commission or other utility regulatory body shall have authorized the
Company to enter, and (b) the term "Subsidiary" shall mean any corporation,
a majority of the voting stock of which is owned by the Company or by one or
more Subsidiaries or by the Company and one or more Subsidiaries.

    SECTION 3.  The Company will not permit the aggregate principal amount
of its First Mortgage Bonds outstanding under the Indenture at any time to
exceed $411,313,000; provided that, for purposes of this Section 3, those
First Mortgage Bonds, 12.22% Series due 2000 tendered in exchange for Bonds
of the 2000 Exchange Series shall not be deemed to be outstanding on the
date of the initial authentication and delivery of the Bonds of the 2000
Exchange Series and; provided, further, that, for purposes of this Section
3, if First Mortgage Bonds ("Refunding Bonds") shall have been issued and
authenticated for the purpose of refinancing outstanding First Mortgage
Bonds ("Refunded Bonds") and the corresponding Refunded Bonds shall have
been irrevocably called for redemption and the proceeds of the Refunding
Bonds shall have been deposited with the Trustee, such Refunded Bonds shall
not be deemed to be outstanding.

                                 ARTICLE IV.

                                 THE TRUSTEE

        The Trustee hereby accepts the trusts created by this Supplemental
Indenture upon the terms and conditions in the Original Indenture as

outstanding or hereinafter issued under the Indenture.  All terms defined in
Article I of the Original Indenture, as heretofore supplemented and amended,

             FIRST MORTGAGE BOND, 12.22% EXCHANGE SERIES DUE 2000

                               DUE JUNE 1, 2000

      TUCSON ELECTRIC POWER COMPANY, a corporation of the State of Arizona
(hereinafter sometimes called the Company), for value received, promises to
pay to _________________________________________________________________ ,
or registered assigns, the principal sum of
                                                                       DOLLARS

on June 1, 2000, in coin or currency of the United States of America which
at the time of payment  shall be legal tender for the payment of public and
private debts, at the office or agency of the Company in the Borough of
Manhattan, The City of New York, or in the City of Tucson, and semi-
annually, on June 1 and December 1 in each year, to pay interest (computed
on the basis of a 360-day year of twelve 30-day months) thereon in like coin
or currency at said office or agency, at the rate of 12.22% per annum, from
the semi-annual interest payment date next preceding the date of this bond
(unless this bond be dated on an interest payment date, in which case from
the date hereof; or unless this bond be dated prior to the first interest
payment date in respect hereof, in which case from the beginning of the
first interest period for bonds of this series), until the Company's
obligation with respect to such principal sum shall be discharged, and, to
the extent permitted by applicable law, at the rate of 12.22% per annum
(computed as set forth above) on any overdue payment of principal of or
premium, if any, or interest on this bond.  The interest so payable on any
June 1 or December 1 will, subject to certain exceptions provided in the
Thirty-Third Supplemental Indenture, dated as of May 1, 1998, hereinafter
referred to, be paid to the person in whose name this bond is registered at
the close of business on the May 15 or November 15 next preceding such June
1 or December 1.  Notwithstanding any provision to the contrary in this bond
or in the Indenture hereinafter referred to, a holder of this bond may elect
to receive payments of the principal of, and the interest, and premium, if
any, on this bond (other than at maturity or upon redemption of the bonds of
this series as a whole) by wire transfer of immediately available funds to
an account maintained by such holder at a bank located in the United States
of America if appropriate wire transfer instructions are received by such
office or agency of the Company not less than 15 calendar days prior to the
date for payment.

    This bond is one of an issue of bonds of the Company, issued and to be
issued in one or more series under and equally and ratably secured (except
as any sinking, amortization, improvement, renewal or other fund,
established in accordance with the provisions of the indenture hereinafter
mentioned, may afford additional security for the bonds of any particular
series) by a certain mortgage and deed of trust (which, together with all
indentures supplemental thereto, including the Thirty-Third Supplemental
Indenture, dated as of May 1, 1998, is hereinafter called the "Indenture"),
dated as of April 1, 1941, made by The Tucson Gas, Electric Light and Power
Company (Tucson Electric Power Company, successor by merger) to The Chase
National Bank of the City of New York (The Chase Manhattan Bank, successor
by merger), now The Chase Manhattan Bank, as Trustee (hereinafter called the
"Trustee"), to which Indenture reference is hereby made for a description of
the property mortgaged and pledged, the nature and extent of the security
provided by the Indenture, the rights and limitations of rights of the
Company, the Trustee and the holders of said bonds with respect to the
security provided by the Indenture, the powers, duties and immunities of the
Trustee, the terms and conditions upon which said bonds are and are to be
secured, and the circumstances under which additional bonds may be issued,
to all of which provisions the holder, by accepting this bond, assents.  To
the extent permitted by and as provided in the Indenture, the rights and
obligations of the Company and the rights of the holders of said bonds may
be changed and modified, with the consent of the Company, by the affirmative
vote of the holders of at least 75% in aggregate principal amount of the
bonds then outstanding (excluding bonds disqualified from voting by reason
of the Company's interest therein as provided in the Indenture), or by the
affirmative vote of the holders of at least 75% in aggregate principal
amount of the bonds of any one or more series then outstanding and entitled
to vote and affected by such modification or alteration in case one or more
but less than all of the series of bonds then outstanding under the
Indenture are so affected, or in either case by the written consent of the
holders of such percentage of bonds; provided, that without the consent of
the holder hereof no such modification or alteration shall be made which
will permit the extension of the time of payment of the principal of or the
interest on this bond or a reduction in the principal amount hereof, or
premium, if any, or rate of interest hereon or any other modification of the
terms of payment of such principal, premium or interest or will deprive the
holder of any lien provided by the Indenture upon the mortgaged property or
reduce the percentage of bonds required for the aforesaid action under the
Indenture.  The Company has reserved the right to amend the Indenture
without any consent or other action by holders of any series of bonds
created after July 31, 1976 (including this series) so as to change 75% in
the foregoing sentence to 60%.  This bond is one of a series of bonds
designated as the First Mortgage Bonds, 12.22% Exchange Series due 2000, of
the Company.

    The bonds of this series are redeemable prior to maturity at the option
of the Company, as a whole at any time, or in part from time to time in a
minimum aggregate principal amount at any one time of not less than
$20,000,000, provided that not less than $20,000,000 in aggregate principal
amount of the bonds of this series remains outstanding after giving effect
to any such partial redemption, upon at least 30 days' prior notice (which
may be conditioned upon the deposit of the redemption moneys with the
Trustee before the redemption date), all as provided in the Indenture, at
the principal amount of bonds so to be redeemed and accrued interest to the
date fixed for redemption, together with an amount equal to the Make-Whole
Premium as such term is defined in said Thirty-Third Supplemental Indenture.
Anything in the Indenture to the contrary notwithstanding and except as set
forth in the next succeeding paragraph, the redemption price for all
redemptions of the bonds of this series shall be the redemption price set
forth in the next preceding sentence, and each redemption of the bonds of
this series shall be pro rata among the bonds of this series as provided in
the Thirty-Third Supplemental Indenture.

    In the event that all or substantially all of the electric utility
properties of the Company at the time subject to the lien of the Indenture
shall be sold, taken by eminent domain or otherwise disposed of, as an
entirety or substantially as an entirety, and shall be released from the
lien of the Indenture, the entire award or other cash proceeds of such sale,
taking or other disposition, together with certain moneys, if any, then held
by the Trustee, shall, to the extent and in the manner provided in the
Indenture, be applied to the pro rata payment or redemption of the bonds of
all series then outstanding under the Indenture, all as more fully provided
therein, and this bond shall, in such event, become subject to such
redemption or payment.  If such sale, taking or other disposition and
release shall be to a municipality or other governmental subdivision or
public authority, or in the event that a controlling interest in the stock
of the Company shall be acquired by or on behalf of a municipality or other
governmental subdivision or public authority which shall cause the
redemption of the bonds of all series then outstanding under the Indenture,
the redemption of this bond shall be at a price equal to its principal
amount, with accrued interest to the date fixed for redemption; all other
redemptions (including, without limitation, all sales, takings, releases and
acquisitions of the sort described above which were negotiated, procured or
the result of action by the Company or any Affiliate of the Company) to be
at the redemption price specified in the next preceding paragraph.

    If this bond or any portion hereof shall be called for redemption and
payment of the redemption price shall be duly provided by the Company as
specified in the Indenture, interest shall cease to accrue on this bond or
such portion hereof from and after the date for redemption fixed in the
notice thereof.

    The principal of this bond and the interest accrued hereon may become or
be declared due and payable before the maturity hereof, on the conditions,
in the manner and at the times set forth in the Indenture, upon the
happening of a default as therein provided.

    Anything in the Indenture to the contrary notwithstanding, upon notice
by the Trustee in writing to the Company pursuant to Section 3 of Article
VIII of the Original Indenture declaring the principal of all bonds
outstanding under the Indenture and the interest accrued thereon immediately
due and payable, the principal of all bonds of this series outstanding under
the Indenture and interest accrued thereon shall, together with, to the
extent provided in the Thirty-Third Supplemental Indenture and permitted by
applicable law, an amount equal to the Make-Whole Premium, as such term is
defined in said Thirty-Third Supplemental Indenture, with respect to such
bonds of this series, become immediately due and payable.

    This bond is transferable by the registered owner hereof in person or by
attorney authorized in writing, at the office or agency of the Company in
the Borough of Manhattan, The City of New York upon surrender and
cancellation of this bond, and upon any such transfer a new bond of this
series, for the same aggregate principal amount, will be issued to the
transferee in exchange herefor. The Company and the Trustee may deem and
treat the person in whose name this bond is registered as the absolute owner
hereof for the purpose of receiving payment and for all other purposes.
This bond, alone or with other bonds of this series, may in like manner be
exchanged at such office or agency for one or more new bonds of this series
of the same aggregate principal amount, all as provided in the Indenture.
Subject to the provisions of the Thirty-Third Supplemental Indenture, dated
as of May 1, 1998, hereinbefore referred to, if this bond is surrendered for
transfer between the record date with respect to any interest payment date
and such interest payment date, the new bond or bonds will be dated as of
such interest payment date.  Upon each such transfer or exchange the Company
may require the payment of any stamp or other tax or governmental charge
incident thereto.

    No recourse shall be had for the payment of the principal of, or
premium, if any, or interest on this bond, or for any claim based hereon or
otherwise in respect hereof or of the Indenture, against any incorporator,
shareholder, director or officer, as such, past, present or future, of the
Company or of any predecessor or successor corporation, either directly or
through the Company or any predecessor or successor corporation, whether by
virtue of any constitution, statute or rule of law, or by the enforcement of
any assessment or penalty or by any legal or equitable proceeding or
otherwise howsoever (including, without limiting the generality of the
foregoing, any proceeding to enforce any claimed liability of shareholders
of the Company, based upon any theory of disregarding the corporate entity
of the Company or upon any theory that the Company was acting as the agent
or instrumentality of the shareholders); all such liability being, by the
acceptance hereof and as a part of the consideration for the issuance
hereof, expressly waived and released by every holder hereof, and being
likewise waived and released by the terms of the Indenture under which this
bond is issued, as more fully provided in said Indenture.

    This bond shall not be valid or become obligatory for any purpose until
the certificate of authentication hereon shall have been signed by The Chase
Manhattan Bank, or its successor, as Trustee under said Indenture.

    IN WITNESS WHEREOF, the Company has caused this bond to be signed in its
name by the manual or facsimile signature of its President or one of its
Vice Presidents, and its corporate seal, or a facsimile thereof, to be
impressed or imprinted hereon and attested by the manual or facsimile
signature of its Secretary or one of its Assistant Secretaries.

                                      ARTICLE I.

                CREATION AND DESCRIPTION OF BONDS OF THE 2008 SERIES.

               SECTION 1. A new series of bonds to be issued under and
          secured by the Indenture is hereby created, to be designated as
          First Mortgage Bonds, Collateral Series due 2008.  The Bonds of
          the 2008 Series shall be limited to an aggregate principal amount
          of One Hundred Forty Million Dollars ($140,000,000), excluding
          any Bonds of the 2008 Series which may be authenticated in
          exchange for or in lieu of or in substitution for or on transfer
          of other Bonds of the 2008 Series pursuant to any provisions of
          the Original Indenture or of this Supplemental Indenture.  Said
          Bonds shall be substantially in the form set forth in Exhibit A
          to this Supplemental Indenture.

               All Bonds of the 2008 Series shall mature August 1, 2008. 
          The Bonds of the 2008 Series shall not bear interest.  The
          principal of the Bonds shall be payable at the office or agency
          of the Company in the Borough of Manhattan, The City of New York,
          or in the City of Tucson, upon presentation thereof, in coin or
          currency of the United States of America which at the time of
          payment shall be legal tender for the payment of public and
          private debts.  

               The Bonds of the 2008 Series shall be issued and delivered
          by the Company to Bank of Montreal Trust Company, as trustee
          under the Indenture, to be dated as of August 1, 1998, as
          supplemented (the "1998 Indenture"), of the Company to such
          trustee (the "1998 Indenture Trustee"), as the basis for the
          authentication and delivery of securities under the 1998
          Indenture.  As provided in the 1998 Indenture, the Bonds of the
          2008 Series, when so issued and delivered, will be registered in
          the name of the 1998 Indenture Trustee or its nominee and will be
          owned and held by the 1998 Indenture Trustee, subject to the
          provisions of the 1998 Indenture, for the benefit of the holders
          of all securities from time to time outstanding under the 1998
          Indenture, and the Company shall have no interest therein.  The
          Bonds of the 2008 Series shall not be transferable except as
          required to effect transfer to any successor trustee under the
          1998 Indenture.


               Anything herein to the contrary notwithstanding, any payment
          by the Company under the 1998 Indenture of the principal of the
          securities which shall have been authenticated and delivered
          under the 1998 Indenture on the basis of the delivery to the 1998
          Indenture Trustee of Bonds of the 2008 Series (other than by the
          application of the proceeds of a payment in respect of such Bonds
          of the 2008 Series) shall, to the extent thereof, be deemed to
          satisfy and discharge the obligation of the Company, if any, to
          make a payment of principal of such Bonds of the 2008 Series
          which is then due.

               The Trustee shall be entitled to presume that the obligation
          of the Company to pay the principal of the Bonds of the 2008
          Series as the same shall become due and payable, whether at
          maturity, upon redemption or otherwise, shall have been fully
          satisfied and discharged unless and until it shall have received
          a written notice from the 1998 Indenture Trustee, signed by an
          authorized officer thereof, stating that the principal of
          specified Bonds of the 2008 Series has become due and payable and
          has not been fully paid, and specifying the amount of funds
          required to make such payment.

               Each Bond shall be dated as provided in SECTION 4 of Article
          II of the Original Indenture and the Bonds of the 2008 Series
          shall be issued in fully registered form only, in denominations
          of $1,000 and multiplies thereof.

               The Bonds of the 2008 Series shall be registrable and
          exchangeable at the office or agency of the Company in the
          Borough of Manhattan, The City of New York in the manner and upon
          the terms set forth in SECTION 5 of Article II of the Original
          Indenture, without payment of any charge.  

               SECTION 2. The Bonds of the 2008 Series may be executed by
          the Company and delivered to the Trustee and, upon compliance
          with all applicable provisions and requirements of the Original
          Indenture in respect thereof, shall be authenticated by the
          Trustee and delivered (without awaiting the filing or recording
          of the Supplemental Indenture) in accordance with the written
          order or orders of the Company.


                                     ARTICLE II.

                      REDEMPTION OF THE BONDS OF THE 2008 SERIES

               SECTION 1. The Bonds of the 2008 Series shall be  redeemable
          prior to maturity at the option of the Company, as a whole at any
          time, or in part from time to time, upon at least 30 days' prior
          notice, all as provided in the Indenture, at the principal amount
          of Bonds so to be redeemed.

               SECTION 2. In the event that all or substantially all of the
          electric utility properties of the Company at the time subject to
          the lien of the Indenture shall be sold, taken by eminent domain
          or otherwise disposed of, as an entirety or substantially as an
          entirety, and shall be released from the lien of the Indenture,
          the entire award or other cash proceeds of such sale, taking or
          other disposition, together with any other Available Moneys (as
          defined in SECTION 11 of Article VII of the Original Indenture),
          if any, then held by the Trustee, shall, to the extent and in the
          manner provided in SECTION 11 of Article VII of the Original
          Indenture, be applied to the pro rata payment or redemption of
          the bonds of all series then outstanding under the Indenture, all
          as more fully provided in the Original Indenture, and the Bonds
          of the 2008 Series shall, in such event, become subject to such
          redemption or payment.  All such redemptions of the Bonds of the
          2008 Series shall be at a redemption price equal to the principal
          amount thereof.

               SECTION 3. All of the provisions of Article V of the
          Original Indenture, other than SECTIONs 2 and 3 thereof and the
          fourth paragraph of SECTION 4 thereof, shall be applicable to the
          redemption of Bonds of the 2008 Series; and the "Available
          Moneys", as defined in SECTION 11 of Article VII of the Original
          Indenture, apportioned to Bonds of the 2008 Series, shall be
          applied by the Trustee to the payment of the redemption price
          thereof, or if such apportioned Available Moneys are insufficient
          for such full payment, then, upon notice similar to that provided
          in the fourth paragraph of said SECTION 11 in respect of the
          bonds referred to therein, first to the payment of the unpaid
          interest accrued to the date fixed for payment and the balance to
          the payment of the then applicable redemption price (exclusive of
          such interest), to the extent that such moneys shall suffice, pro
          rata, as provided in SECTION 11 of Article VII of the Original
          Indenture, upon presentation and stamping in a manner similar to
          that provided by SECTION 11 of Article VII of the Original
          Indenture for the bonds referred to therein and the coupons
          appurtenant thereto.   Until the full amount then due and owing
          on all Bonds of the 2008 Series shall have been paid, no such
          partial payment shall discharge the obligation of the Company on
          such Bonds, except to the extent of such partial payment; and the
          balance of principal, if any, remaining after such payment shall
          thereafter constitute the unpaid obligation of the Company upon
          the Bonds of the 2008 Series.

               SECTION 4. The holder of each and every Bond of the 2008
          Series issued hereunder hereby agrees to accept payment thereof
          prior to maturity on the terms and conditions provided for in
          this Article II.


                                     ARTICLE III.

               than 10 days prior to the date of such application, stating
               that the signers have no knowledge of and do not believe
               that there have been, since the close of the period covered
               by the Engineer's Certificate specified in subdivision (3)
               above, property retirements in an amount which (after
               reduction of such amount by amounts of the character
               referred to in Clause (D) of subdivision 3 in respect of
               such property retirements) exceeds the amount of property
               additions since the close of such period by more than the
               amount of the unapplied balance of property additions
               calculated to be remaining upon the granting of the
               application (before any reduction of such unapplied balance
               of property additions by any amount of net property
               additions applied to the withdrawal of cash deposited with
               the Trustee in connection with such property retirements).

               SECTION 2.  SECTION 1 of Article VIII of the Original
          Indenture is hereby amended to:

               (a)  insert ";or" at the end of clause (f) therein; and

               (b)  add immediately following clause (f) the following:

                         "(g) so long as the trustee under the Indenture,
                    dated as of August 1, 1998 as the same may be amended
                    and supplemented (the '1998 Indenture'), from the
                    Company to Bank of Montreal Trust Company, trustee (the
                    '1998 Indenture Trustee'), shall hold any bond
                    outstanding hereunder which were delivered to the 1998
                    Indenture Trustee as the basis for the authentication
                    and delivery of securities under the 1998 Indenture
                    which remain outstanding thereunder, an 'Event of
                    Default' under the 1998 Indenture; provided, however,
                    that, anything in this Indenture to the contrary
                    notwithstanding, the waiver or cure of such 'Event of
                    Default' and the rescission and annulment of the
                    consequences thereof shall constitute a cure of the
                    corresponding default under this Indenture and a
                    rescission and annulment of the consequences thereof."


               SECTION 3.  The holders of the Bonds of the 2008 Series
          shall be deemed to have consented to the execution and delivery
          of a supplemental indenture containing one or more, or all, of
          the amendments to the Original Indenture set forth on Exhibit B
          to this Supplemental Indenture.

               SECTION 4.  Subject to the variations contained in Article
          II of this Supplemental Indenture and the amendments heretofore
          made or contemplated in this Article IV, the Original Indenture,
          as heretofore modified, amended and supplemented, is in all
          respect ratified and confirmed, and the Original Indenture, this
          Supplemental Indenture and all other indentures supplemental to
          the Original Indenture shall be read, taken and construed as one
          and the same instrument.  Neither the execution of this
          Supplemental Indenture nor anything herein contained shall be
          construed to impair the lien of the Indenture on any of the
          property subject thereto, and such lien shall remain in full
          force and effect as security for all Bonds now outstanding or
          hereinafter issued under the Indenture.  All terms defined in
          Article I of the Original Indenture, as heretofore supplemented
          and amended, shall, for all purposes of this Supplemental
          Indenture, have the meanings in said Article I specified, unless
          the context otherwise requires.

               SECTION 5. If the date for making any payment or the last
          date for performance of any act or the exercising of any right,
          as provided in this Supplemental Indenture, shall be a legal
          holiday or a day on which banking institutions in The City of New
          York are authorized by law to remain closed, such payment may be
          made or act performed or right exercised on the next succeeding
          day not a legal holiday or a day on which such banking
          institutions are authorized by law to remain closed, with the
          same force and effect as if done on the nominal date provided in
          this Supplemental Indenture, and no interest shall accrue for the
          period after such nominal date.

               SECTION 6. This Supplemental Indenture may be executed in
          any number of counterparts, and all said counterparts executed
          and delivered, each as an original, shall constitute but one and
          the same instrument.


               IN WITNESS WHEREOF, Tucson Electric Power Company has caused
          its corporate name to be hereunto affixed, and this instrument to
          be signed by its President or a Vice President, and its corporate

          Arizona (hereinafter sometimes called the Company), for value
          received, promises to pay to                                      
                                                 , or registered assigns,
          the principal sum of
                                                                    DOLLARS

             This bond is one of an issue of bonds of the Company, issued
          and to be issued in one or more series under and equally and
          ratably secured (except as any sinking, amortization,
          improvement, renewal or other fund, established in accordance
          with the provisions of the indenture hereinafter mentioned, may
          afford additional security for the bonds of any particular
          series) by a certain mortgage and deed of trust (which, together
          with all indentures supplemental thereto, including the Thirty-
          Fourth Supplemental Indenture, dated as of August 1, 1998, is
          hereinafter called the "Indenture"), dated as of April 1, 1941,

          Electric Power Company, successor by merger) to The Chase
          National Bank of the City of New York (The Chase Manhattan Bank,
          successor by merger), now The Chase Manhattan Bank, as Trustee
          (hereinafter called the "Trustee"), to which Indenture reference
          is hereby made for a description of the property mortgaged and
          pledged, the nature and extent of the security provided by the
          Indenture, the rights and limitations of rights of the Company,
          the Trustee and the holders of said bonds with respect to the
          security provided by the Indenture, the powers, duties and
          immunities of the Trustee, the terms and conditions upon which
          said bonds are and are to be secured, and the circumstances under
          which additional bonds may be issued, to all of which provisions
          the holder, by accepting this bond, assents.  To the extent
          permitted by and as provided in the Indenture, the rights and
          obligations of the Company and the rights of the holders of said
          bonds may be changed and modified, with the consent of the
          Company, by the affirmative vote of the holders of at least 75%
          in aggregate principal amount of the bonds then outstanding
          (excluding bonds disqualified from voting by reason of the
          Company's interest therein as provided in the Indenture), or by
          the affirmative vote of the holders of at least 75% in aggregate
          principal amount of the bonds of any one or more series then
          outstanding and entitled to vote and affected by such
          modification or alteration in case one or more but less than all
          of the series of bonds then outstanding under the Indenture are
          so affected, or in either case by the written consent of the
          holders of such percentage of bonds; provided, that without the
                                               --------
          consent of the holder hereof no such modification or alteration
          shall be made which will permit the extension of the time of
          payment of the principal of or the interest on this bond or a
          reduction in the principal amount hereof, or premium, if any, or
          rate of interest hereon or any other modification of the terms of
          payment of such principal, premium or interest or will deprive
          the holder of any lien provided by the Indenture upon the
          mortgaged property or reduce the percentage of bonds required for
          the aforesaid action under the Indenture.  The Company has
          reserved the right to amend the Indenture without any consent or
          other action by holders of any series of bonds created after
          July 31, 1976 (including this series) so as to change 75% in the
          foregoing sentence to 60%.  This bond is one of a series of bonds
          designated as the First Mortgage Bonds, Collateral Series due
          2008 of the Company.

             The bonds of this series are being issued and delivered by
          the Company to Bank of Montreal Trust Company, as trustee under
          the Indenture, dated as of August 1, 1998, as supplemented (the
          "1998 Indenture"), of the Company to such trustee (the "1998
          Indenture Trustee"), as the basis for the authentication and
          delivery of securities under the 1998 Indenture.  As provided in
          the 1998 Indenture, the bonds of this series are to be registered
          in the name of the 1998 Indenture Trustee or its nominee and will
          be owned and held by the 1998 Indenture Trustee, subject to the
          provisions of the 1998 Indenture, for the benefit of the holders
          of all securities from time to time outstanding under the 1998
          Indenture, and the Company shall have no interest therein.  The
          bonds of this series shall not be transferable except as required
          to effect transfer to any successor trustee under the 1998
          Indenture.

             Anything herein to the contrary notwithstanding, any payment
          by the Company under the 1998 Indenture of the principal of the
          securities which shall have been authenticated and delivered
          under the 1998 Indenture on the basis of the delivery to the 1998
          Indenture Trustee of bonds of this series (other than by the
          application of the proceeds of a payment in respect of such bonds
          of this series) shall, to the extent thereof, be deemed to
          satisfy and discharge the obligation of the Company, if any, to
          make a payment of principal of such bonds of this series which is
          then due.

             The bonds of this series are redeemable prior to maturity at
          the option of the Company, as a whole at any time, or in part
          from time to time, upon at least 30 days' prior notice (which may
          be conditioned upon the deposit of the redemption moneys with the
          Trustee before the redemption date), all as provided in the
          Indenture, at the principal amount of bonds so to be redeemed. 

             In the event that all or substantially all of the electric
          utility properties of the Company at the time subject to the lien
          of the Indenture shall be sold, taken by eminent domain or
          otherwise disposed of, as an entirety or substantially as an
          entirety, and shall be released from the lien of the Indenture,
          the entire award or other cash proceeds of such sale, taking or
          other disposition, together with certain moneys, if any, then
          held by the Trustee, shall, to the extent and in the manner
          provided in the Indenture, be applied to the pro rata payment or
          redemption of the bonds of all series then outstanding under the
          Indenture, all as more fully provided therein, and this bond
          shall, in such event, become subject to such redemption or
          payment.  Any such redemption of this bond shall be at a
          redemption price equal to its principal amount.

             The principal of this bond may become or be declared due and
          payable before the maturity hereof, on the conditions, in the
          manner and at the times set forth in the Indenture, upon the
          happening of a default as therein provided.

             This bond is non-transferable except as required to effect
          transfer to any successor trustee under the 1998 Indenture, any
          such transfer to be made, at the office or agency of the Company
          in the Borough of Manhattan, The City of New York upon surrender
          and cancellation of this bond, and upon any such transfer a new
          bond of this series, for the same aggregate principal amount,
          will be issued to the transferee in exchange herefor. The Company
          and the Trustee may deem and treat the person in whose name this
          bond is registered as the absolute owner hereof for the purpose
          of receiving payment and for all other purposes.  This bond,
          alone or with other bonds of this series, may in like manner be
          exchanged at such office or agency for one or more new bonds of
          this series of the same aggregate principal amount, all as
          provided in the Indenture.

             No recourse shall be had for the payment of the principal of
          this bond, or for any claim based hereon or otherwise in respect
          hereof or of the Indenture, against any incorporator,
          shareholder, director or officer, as such, past, present or
          future, of the Company or of any predecessor or successor
          corporation, either directly or through the Company or any
          predecessor or successor corporation, whether by virtue of any
          constitution, statute or rule of law, or by the enforcement of
          any assessment or penalty or by any legal or equitable proceeding
          or otherwise howsoever (including, without limiting the
          generality of the foregoing, any proceeding to enforce any
          claimed liability of shareholders of the Company, based upon any
          theory of disregarding the corporate entity of the Company or
          upon any theory that the Company was acting as the agent or
          instrumentality of the shareholders); all such liability being,
          by the acceptance hereof and as a part of the consideration for
          the issuance hereof, expressly waived and released by every
          holder hereof, and being likewise waived and released by the
          terms of the Indenture under which this bond is issued, as more
          fully provided in said Indenture.

             This bond shall not be valid or become obligatory for any
          purpose until the certificate of authentication hereon shall have

          payable to the Trustee as its interest may appear, unless
          required by the terms of any prior lien to be paid to the trustee
          or other holder thereof, as evidenced by an opinion of counsel. 
          If the Company shall insure such property in whole or in part
          through an insurance fund, trust or other agreement, it hereby
          covenants and agrees to pay to the Trustee the amount of all
          losses, except in respect of any particular loss less than
          5%<FN6> of the aggregate principal amount of bonds outstanding
          hereunder, to the extent that such amounts shall not be payable
          by insurance companies, and the amounts so required to be paid to
          the Trustee (as well as the amounts of all losses permitted to be
          retained by the Company because not in excess of 5% of the
          aggregate principal amount of bonds outstanding hereunder) shall
          be deemed to constitute proceeds of insurance for all purposes of
          this Indenture.  All moneys received by the Trustee as proceeds
          of insurance against loss or damage shall be held and applied as
          hereinafter provided.  On or prior to September 15 in each year,
          and at any other time upon the written request of the Trustee,
          the Company will furnish to the Trustee a Treasurer's certificate
          stating in substance that the Company has complied with all the
          terms and conditions of this Section, containing a detailed
          statement of the insurance then in effect upon the property of
          the Company on a date therein specified (which date shall be
          within 30 days of the filing of such certificate) and, except in
          respect of property insured by means of an insurance fund, trust
          or other agreement as permitted by this Section, showing the
          numbers of the policies of insurance in effect and the names of
          the issuing companies, the amounts of such policies, the
          deductible provisions of such policies and the property covered
          by such policies; and, in case any of the property shall at the
          time be insured by means of an insurance fund, trust or other
          agreement, as permitted by this Section, the Company shall, at
          the time of furnishing each such Treasurer's certificate, also
          furnish to the Trustee a certificate, as described above, with
          respect to the adequacy of such insurance fund, trust or other
          arrangement.  Subject to the provisions of Section 2 of Article
          XII hereof, the Trustee shall be entitled to accept any such
          Treasurer's certificate, and, if required, any such other
          certificate above described, as satisfactory evidence of
          compliance by the Company with the provisions of this Section,
          and shall be under no duty with respect to any such Treasurer's
          certificate or any such other certificate, except to exhibit the
          same to any bondholder upon request."

               11.  The modification of Section 4 of Article VII of the
          Original Indenture to read as follows:

                  "Section 4. Unless a default as defined in Section 1 of
          Article VIII hereof shall have happened and shall be continuing,
          the Trustee shall, whenever from time to time requested by the
          Company, and after being furnished with a certificate and opinion
          of counsel that all conditions precedent to the release in this
          Section provided for have been complied with, and without
          requiring compliance with any of the foregoing provisions of
          Section 3 of this Article (but subject to the requirements of
          Section 19 of Article IV hereof), release from the lien hereof
          any property (except cash, obligations or other personal property
          deposited or pledged or required to be deposited or pledged with
          the Trustee) which, as set forth in the certificate or opinion of
          an engineer, appraiser, or other expert furnished to the Trustee
          pursuant to Section 19 of Article IV hereof, is of a value not
          exceeding, in the aggregate in any period of 12 consecutive
          calendar months the greater of the sum of $25,000 or 1% of the
          aggregate principal amount of bonds at the time outstanding.  The
          Company covenants that it will forthwith deposit with the Trustee
          the consideration received by it from the disposition of any
          property so released, to be held and applied as a part of the
          mortgaged property, in the manner provided in Section 9 of this
          Article, or with the trustee or other holder of a prior lien, if
          required by the terms thereof, as evidenced by an opinion of
          counsel."


               12.  The modification of the first proviso of Section 5 of
          Article IV of the Original Indenture to read as follows:

                  "provided, however, that nothing in this Section 5
               contained shall require the Company to observe or conform to
               any requirement of governmental authority or to pay, or
               cause to be paid or discharged, or make provision for, any
               such tax, assessment, lien or charge, (a) so long as the
               validity thereof shall be contested in good faith and by
               appropriate proceedings or (b) with respect to any such
               requirement of governmental authority, so long as the
               Company shall be in good faith doing all things
               technologically and economically feasible and prudent on its
               part to observe or conform to such requirement, unless, in
               any case, any part of the mortgaged property will thereby be
               lost or forfeited;"

               13.  (a) The modification of the first sentence of Section 3
          of Article VII of the Original Indenture to read as follows:

                  "Section 3. The Company shall have the right (in addition
               to the rights conferred by Sections 2, 4 and 5 of this
               Article) at any time and from time to time, unless a default
               as defined in Section 1 of Article VIII hereof shall have
               happened and shall be continuing, to sell, dispose of or
               exchange any part of the mortgaged property (other than any
               cash, obligations or other personal property deposited or
               pledged with or required to be deposited or pledged with the
               Trustee) the ownership of which by the Company shall no
               longer be desirable in the judicious management and
               maintenance of the mortgaged property or in the conduct of
               the business of the Company, or which the Company shall have
               been directed to sell or dispose of by order of any
               governmental authority having jurisdiction in the premises,
               or shall desire to sell or dispose of in reasonable
               anticipation of the making of such an order."

                                                                      ; and

               (b)  The modification of Clause (C)(1) of Section 3 of
          Article VII of the Original Indenture to read as follows:

                  "(1) that the Company has sold, disposed of or exchanged
               or has contracted to sell, dispose of or exchange the
               property so to be released for a consideration described, in
               reasonable detail, in said certificate, and either (a) that
               such sale or exchange is desirable in the conduct of the
               business of the Company, and that the ownership by the
               Company of the property to be released is no longer
               desirable in the judicious management and maintenance of the
               mortgaged property or in the conduct of the business of the
               Company, or (b) that such sale or disposition is made to
               comply with an order or orders of a designated governmental
               authority having jurisdiction to require such sale or
               disposition, or in reasonable anticipation of the making of
               such an order;".

               14.  The amendment of Section 2 of Article I of the Original
          Indenture to add thereto a definition of the term "fair value"
          substantially to the following effect:

                  "Fair value", with respect to property, shall mean the
               fair value of such property as may be determined by
               reference to (a) the amount which would be likely to be
               obtained in an arm's-length transaction with respect to such
               property between an informed and willing buyer and an
               informed and willing seller, under no compulsion,
               respectively, to buy or sell, (b) the amount of investment
               with respect to such property which, together with a
               reasonable return thereon, would be likely to be recovered
               through ordinary business operations or otherwise, (c) the
               cost, accumulated depreciation and replacement cost with
               respect to such property and/or (d) any other relevant
               factors; provided, however, that (x) the fair value of
               property shall be determined without deduction for any prior
               liens on such property (except as otherwise provided in
               clause (2) of subparagraph (C) of Section 3 of Article VII
               and (y) the fair value to the Company of property additions
               shall not reflect any reduction relating to the fact that
               such property additions may be of less value to a person
               which is not the owner or operator of the mortgaged property
               or any portion thereof than to a person which is such owner
               or operator. Fair value may be determined, without physical
               inspection, by the use of accounting and engineering records
               and other data maintained by the Company or otherwise
               available to the engineer certifying the same.

               15.  The amendment of Section 2 of Article I of the Original
          Indenture to add thereto definitions of the terms "purchase money
          mortgage" and "purchase money obligations" substantially to the
          following effect:

                  "Purchase money mortgage" means, with respect to any
               property being acquired or disposed of by the Company or
               being released from the lien of this Indenture, a lien on
               such property which

                    (a)  is taken or retained by the transferor of such
                  property to secure all or part of the purchase price
                  thereof;

                    (b)  is granted to one or more persons other than the
                  transferor which, by making advances or incurring an
                  obligation, give value to enable the grantor of such lien
                  to acquire rights in or the use of such property;

                    (c)  is granted to any other person in connection with
                  the release of such property from the lien of this
                  Indenture on the basis of the deposit with the Trustee or
                  the trustee or other holder of a prior lien of
                  obligations secured by such lien on such property (as
                  well as any other property subject thereto);

                    (d)  is held by a trustee or agent for the benefit of
                  one or more persons described in clause (a), (b) and/or
                  (c) above, provided that such lien may be held, in
                  addition, for the benefit of one or more other persons
                  which shall have theretofore given, or may thereafter
                  give, value to or for the benefit or account of the
                  grantor of such lien for one or more other purposes; or

                    (e)  otherwise constitutes a purchase money mortgage or
                  a purchase money security interest under applicable law;

               and, without limiting the generality of the foregoing, for
               purposes of this Indenture, the term shall be deemed to
               include any lien described above whether or not such lien
               (x) shall permit the issuance or other incurrence of
               additional indebtedness secured by such lien on such
               property, (y) shall permit the subjection to such lien of
               additional property and the issuance or other incurrence of
               additional indebtedness on the basis thereof and/or (z)
               shall have been granted prior to the acquisition,
               disposition or release of such property, shall attach to or
               otherwise cover property other than the property being
               acquired, disposed of or released and/or shall secure
               obligations issued prior and/or subsequent to the issuance
               of the obligations delivered in connection with such
               acquisition, disposition or release.  The term "purchase
               money obligation" shall mean an obligation secured by a
               purchase money mortgage.

               16.  The amendment of clause (b) in subdivision (1) of
          Section 9 of Article VII or the Original Indenture to read as
          follows:

                    (b)  in an amount equal to 166 2/3% of the principal
                  amount of bonds to the authentication and delivery of
                  which the Company shall be entitled under the provisions
                  of Section 7 of Article III hereof.

               17.  The amendment of the first paragraph of Section 3 of
          Article VII of the Original Indenture to:

                  (i)         to delete therefrom the proviso in the second
               sentence of such paragraph or to provide that such proviso
               may be disregarded upon specified conditions; or

                  (ii)   to delete from such proviso the phrase "15% of";
               or

                  (iii)  to change the term 15% in such proviso therein to
               any higher percentage not exceeding one hundred per centum
               (100%).

               18.  The amendment of Section 7 of Article III of the
          Original Indenture change the semi-colon at the end of clause (4)
          in the first paragraph thereof to a period and to delete the
          remainder of said first paragraph.


                                                             Exhibit 4(c)

          to other persons at or prior to the time of the issuance and
          delivery of the Bonds of the Initial Series, including, but not

          of the purchase money placed thereon, at the time of such
          acquisition, it being understood that with respect to any such
          after-acquired property the Lien of the Indenture (as hereinafter
          defined) shall at all times be junior, subject and subordinate to
          the lien of the 1941 Mortgage and the security interest created
          thereby; and subject also to the provisions of Article XI of the
          Original Indenture;

          preference or priority of any one Bond over any other by reason
          of priority in the time of issue, sale or negotiation thereof or
          otherwise, except as provided in Section 2 of Article IV of the
          Original Indenture, so that, subject to said provisions, each and
          all of said Bonds shall have the same right, lien and privilege
          under the Indenture and shall be equally secured hereby (except
          as any sinking, amortization, improvement, renewal or other fund,
          established in accordance with the provisions of the Indenture,
          may afford additional security for the Bonds of any particular
          series), and shall have the same proportionate interest and share
          in the Trust Estate, with the same effect as if all of the Bonds
          had been issued, sold and negotiated simultaneously on the date
          of the delivery hereof; and in trust for enforcing payment of the
          principal of the Bonds, and premium, if any, and interest, if
          any, thereon, according to the tenor, purport and effect of the
          Bonds and of the Indenture, and for enforcing the terms,
          provisions, covenants and agreements herein and in the Bonds set
          forth;

               UPON CONDITION that, until the happening of a Default, the
          Company shall be suffered and permitted to possess, use and enjoy
          the Trust Estate (except money, securities and other personal
          property pledged or deposited with or required to be pledged or
          deposited with the Trustee hereunder) and to receive and use the
          rents, issues, income, revenues, earnings and profits therefrom,
          all as more specifically provided in Section 1 of Article VII of
          the Original Indenture;

               AND UPON THE TRUSTS, USES AND PURPOSES and subject to the
          covenants, agreements and conditions hereinafter set forth and
          declared.

                    (a)  Anything herein to the contrary notwithstanding,
               any payment by the Company under the 1998 Indenture of the
               principal of the securities which shall have been
               authenticated and delivered under the 1998 Indenture on the
               basis of the delivery to the 1998 Indenture Trustee of
               Series 3 Bonds (other than by the application of the
               proceeds of a payment in respect of such Series 3 Bonds)
               shall, to the extent thereof, be deemed to satisfy and
               discharge the obligation of the Company, if any, to make a
               payment of principal of such Series 3 Bonds which is then
               due.

                         The Trustee shall be entitled to presume that the
               obligation of the Company to pay the principal of the Series
               3 Bonds as the same shall become due and payable, whether at
               maturity, upon redemption or otherwise, shall have been
               fully satisfied and discharged unless and until it shall
               have received a written notice from the 1998 Indenture
               Trustee, signed by an authorized officer thereof, stating
               that the principal of specified Series 3 Bonds has become
               due and payable and has not been fully paid, and specifying
               the amount of funds required to make such payment.

                    (b)  the Series 3 Bonds shall have such other terms,
               and shall bear such restrictive legends, as are set forth in
               the form of Series 3 Bond attached hereto as Exhibit A; 

                    (c)  if the Company shall make any deposit of money
               and/or Government Obligations with respect to any Series 3
               Bonds, or any portion of the principal amount thereof, as
               contemplated by SECTION 1 of Article XV of the Original
               Indenture, then the Company shall not deliver a Treasurer's
               Certificate described in clause (z) in the first paragraph
               of said SECTION 1 unless the Company shall also deliver to
               the Trustee, together with such other Treasurer's
               Certificate either:

                         i)   an instrument wherein the Company,
                    notwithstanding the satisfaction and discharge of its
                    indebtedness in respect of the such Series 3 Bonds,
                    shall assume the obligation (which shall be absolute
                    and unconditional) to irrevocably deposit with the
                    Trustee such additional sums of money, if any, or
                    additional Government Obligations (meeting the
                    requirements of said SECTION 1 of Article XV), if any,
                    or any combination thereof, at such time or times, as
                    shall be necessary, together with the money and/or
                    Government Obligations theretofore so deposited, to pay
                    when due the principal of such Series 3 Bonds or
                    portions thereof, all in accordance with and subject to
                    the provisions of said SECTION 1; provided, however,
                    that such instrument may state that the obligation of
                    the Company to make additional deposits as aforesaid
                    shall be subject to the delivery to the Company by the
                    Trustee of a notice asserting the deficiency
                    accompanied by an opinion of an Independent public
                    accountant of nationally recognized standing showing
                    the calculation thereof (which opinion shall be
                    obtained at the expense of the Company); or

                         ii)  an Opinion of Counsel to the effect that the
                    Holders of such Series 3 Bonds, or portions of the
                    principal amount thereof, will not recognize income,
                    gain or loss for United States federal income tax
                    purposes as a result of the satisfaction and discharge
                    of the Company's indebtedness in respect thereof and
                    will be subject to United States federal income tax on
                    the same amounts, at the same times and in the same
                    manner as if such satisfaction and discharge had not
                    been effected.


                                      ARTICLE II.

          Original Indenture set forth in Schedule D hereto.

                    any purpose, including for the purpose of determining
                    the principal amount of such Bonds deemed to be
                    Outstanding at any time; it being understood that, for
                    purposes of calculations under this Indenture
                    (including calculations under Articles I and III), any
                    amounts denominated in a currency other than Dollars or
                    in a composite currency shall be converted to Dollar
                    equivalents by calculating the amount of Dollars which
                    could have been purchased by the amount of such other
                    currency based on such quotations or methods of
                    determination as shall be specified pursuant to this
                    clause; provided, however, that the instrument
                    establishing the Bonds of such series or Tranche shall
                    contain provisions substantially to the effect that if,
                    at any time when the principal of such Bonds, together
                    with premium, if any, and accrued interest, if any,
                    thereon, shall be due and payable or at any time when
                    there shall be a determination by a court of competent
                    jurisdiction of the extent to which the obligations of
                    the Company in respect of the Bonds then Outstanding or
                    otherwise under this Indenture are deemed to be secured
                    obligations of the Company, the amount of Dollars into
                    which an amount equal to the principal of such Bonds
                    could be converted under then current currency exchange
                    rates exceeds the amount of Dollars into which an
                    amount equal to the principal of such Bonds have been
                    converted under currency exchange rates prevailing at
                    the time of the initial authentication and delivery of
                    such Bonds, then the Company's obligation to pay such
                    excess amount in respect of principal, together with
                    the associated excess amounts in respect of premium, if
                    any, and accrued interest, if any, shall be deemed to
                    be secured by and entitled to the benefit of the Lien
                    of this Indenture only to the extent that any proceeds
                    of sale of the Trust Estate and/or any other assets of
                    the Company subject to such Lien shall exceed the
                    amount necessary to pay, satisfy and discharge, or duly
                    provide therefor, all other obligations of the Company
                    on the Bonds then Outstanding or otherwise under this
                    Indenture; and, to the extent of any inconsistency
                    between such provisions so contained in such instrument
                    and any other provision of this Indenture, such
                    provisions of such instrument shall control;

                         (k)  if the principal of or premium, if any, or
                    interest, if any, on the Bonds of such series, or any
                    Tranche thereof, are to be payable, at the election of
                    the Company or a Holder thereof, in a coin or currency
                    other than that in which the Bonds are stated to be
                    payable, the coin or currency in which payment of any
                    amount as to which such election is made will be
                    payable, the period or periods within which, and the
                    terms and conditions upon which, such election may be
                    made; it being understood that, for purposes of
                    calculations under this Indenture (including
                    calculations under Articles I and III), any such
                    election shall be required to be taken into account, in
                    the manner contemplated in clause (j) of this
                    paragraph, only after such election shall have been
                    made; provided, however, the instrument establishing
                    the Bonds of such series or Tranche shall contain
                    provisions having substantially the same effect as the
                    provisions described in the proviso to clause (j) of
                    this paragraph;

                         (l)  if the principal of or premium, if any, or
                    interest, if any, on the Bonds of such series, or any
                    Tranche thereof, are to be payable, or are to be
                    payable at the election of the Company or a Holder
                    thereof, in securities or other property, the type and
                    amount of such securities or other property, or the
                    formulary or other method or other means by which such
                    amount shall be determined, and the period or periods
                    within which, and the terms and conditions upon which,
                    any such election may be made; it being understood that
                    all calculations under this Indenture (including
                    calculations under Articles I and III) shall be made on
                    the basis of the fair market value of such securities
                    or the fair value of such other property, in either
                    case determined as of the most recent practicable date,
                    except that, in the case of any amount of principal or
                    interest that may be so payable at the election of the
                    Company or a Holder, if such election shall not yet
                    have been made, such calculations shall be made on the
                    basis of the amount of principal or interest, as the
                    case may be, that would be payable if no such election
                    were made; provided, however, the instrument
                    establishing the Bonds of such series or Tranche shall
                    contain provisions having substantially the same effect
                    as the provisions described in the proviso to clause
                    (j) of this paragraph;

                         (m)  if the amount payable in respect of principal
                    of or premium, if any, or interest, if any, on the
                    Bonds of such series, or any Tranche thereof, may be
                    determined with reference to an index or other fact or
                    event ascertainable outside of this Indenture, the
                    manner in which such amounts shall be determined (to
                    the extent not established pursuant to clause (e) of
                    this paragraph); it being understood that all
                    calculations under this Indenture (including
                    calculations under Articles I and III) shall be made on
                    the basis of the amount that would be payable as
                    principal if such principal were due, or on the basis
                    of the interest rates in effect, as the case may be, on
                    the date next preceding the date of such calculation;
                    provided, however, the instrument establishing the
                    Bonds of such series or Tranche shall contain
                    provisions having substantially the same effect as the
                    provisions described in the proviso to clause (j) of
                    this paragraph;

                         (n)  if other than the principal amount thereof,
                    the portion of the principal amount of Bonds of such
                    series, or any Tranche thereof, which shall be payable
                    upon declaration of acceleration of the Maturity
                    thereof pursuant to SECTION 3 of Article VIII;
                    
                         (o)  the terms, if any, pursuant to which the
                    Bonds of such series, or any Tranche thereof, may be
                    converted into or exchanged for shares of capital stock
                    or other securities of the Company or any other Person;

                         (p)  the obligations or instruments, if any, which
                    shall be considered to be Eligible Obligations in
                    respect of the Bonds of such series, or any Tranche
                    thereof, denominated in a currency other than Dollars
                    or in a composite currency, and any additional or
                    alternative provisions for the reinstatement of the
                    Company's indebtedness in respect of such Bonds after
                    the satisfaction and discharge thereof as provided in
                    SECTION 1 of Article XV;

                         (q)  if the Bonds of such series, or any Tranche
                    thereof, are to be issued in global form, (i) any
                    limitations on the rights of the Holder or Holders of
                    such Bonds to transfer or exchange the same or to
                    obtain the registration of transfer thereof, (ii) any
                    limitations on the rights of the Holder or Holders
                    thereof to obtain certificates therefor in definitive
                    form in lieu of temporary form and (iii) any and all
                    other matters incidental to such Bonds;

                         (r)  if the Bonds of such series, or any Tranche
                    thereof, are to be issuable as bearer securities, any
                    and all matters incidental thereto which are not
                    specifically addressed in a supplemental indenture as
                    contemplated by clause (f) of SECTION 2 of Article
                    XIII;

                         (s)  to the extent not established pursuant to
                    clause (q) of this paragraph, any limitations on the
                    rights of the Holders of the Bonds of such Series, or
                    any Tranche thereof, to transfer or exchange such Bonds
                    or to obtain the registration of transfer thereof; and
                    if a service charge will be made for the registration
                    of transfer or exchange of Bonds of such series, or any
                    Tranche thereof, the amount or terms thereof;

                         (t)  any exceptions to SECTION 13 of Article XVI
                    with respect to the Bonds of such series, or any
                    Tranche thereof; and

                         (u)  any other terms of the Bonds of such series,
                    or any Tranche thereof.

                    With respect to Bonds of a series subject to a Periodic
               Offering, the indenture supplemental hereto, Certified
               Resolution or Treasurer's Certificate which establishes such
               series may provide general terms or parameters for Bonds of
               such series and provide either that the specific terms of
               Bonds of such series, or any Tranche thereof, shall be
               specified in a Written Order or that such terms shall be
               determined by the Company or its agents in accordance with
               procedures specified therein or to be specified in a Written
               Order.

                    The form of the Bonds of each series, or any Tranche
               thereof, shall be set forth in a supplemental indenture,
               Certified Resolution or Treasurer's Certificate.

                    (b)  SECTION 1 of Article I of the Original Indenture
          is hereby amended to include therein the following additional
          definitions:

                    "DOLLAR" or "$" shall mean a dollar or other equivalent
               unit in such coin or currency of the United States of
               America as at the time shall be legal tender for the payment
               of public and private debts.

                    "ELIGIBLE OBLIGATIONS" shall mean:

                         (a)  with respect to Bonds denominated in Dollars,
                    Government Obligations; or

                         (b)  with respect to Bonds denominated in a
                    currency other than Dollars or in a composite currency,
                    such other obligations or instruments as shall be
                    specified with respect to such Securities as
                    contemplated by SECTION 2 of Article II.

                    "INTEREST PAYMENT DATE", when used with respect to any
               Bond, shall mean the Stated Maturity of an installment of
               interest on such Bond.

                    "MATURITY", when used with respect to any Bond, shall
               mean the date on which the principal of such Bond or an
               installment of principal becomes due and payable as provided
               in such Bond or in this Indenture, whether at the stated
               maturity, by declaration of acceleration, upon call for
               redemption or otherwise.

                    "STATED MATURITY", when used with respect to any
               obligation or any installment of principal thereof or
               interest thereon, shall mean the date on which the principal
               of such obligation or such installment of principal or
               interest is stated to be due and payable (without regard to
               any provisions for redemption, prepayment, acceleration,
               purchase or extension).

                    (c)  Article XV of the Original Indenture is hereby
          amended by substituting the term "Eligible Obligations" for the
          term "Government Obligations" wherever in such Article the latter
          term currently appears.

               (2)  The definition of the term "Retired Bond" in SECTION 2
          of Article I of the Original Indenture is hereby amended to read
          as follows:

                    "RETIRED BOND" shall mean, as of any time, (a) any Bond
               authenticated and delivered under this Indenture which no
               longer remains Outstanding by reason of the applicability of
               clause (a)  or (b) in the definition of "OUTSTANDING" (other
               than any Predecessor Bond of any Bond), provided, however,
               that no Bond which shall have ceased to be Outstanding prior
               to the Initial Certification Date shall be deemed to be a
               Retired Bond unless such Bond shall have been included in
               the Initial Engineer's Certificate as if such Bond had been
               Outstanding at the Initial Certification Date; and (b) any
               bond authenticated and delivered under the 1941 Mortgage
               which at such time could be used as the basis for the
               authentication and delivery of additional bonds pursuant to
               SECTION 7 of Article III of the 1941 Mortgage, provided,
               however, that (x) no bond which shall have ceased to be
               "outstanding" under the 1941 Mortgage prior to the Initial
               Certification Date shall be deemed to be a Retired Bond
               unless such bond shall have been included in the Initial
               Engineer's Certificate as if such bond had been
               "outstanding" at the Initial Certification Date and (y) any
               bond which shall have ceased to be "outstanding" under the
               1941 Mortgage on or after the Initial Certification Date and
               could otherwise have been used under SECTION 7 of Article
               III of the 1941 Mortgage shall be deemed to be a Retired
               Bond notwithstanding any subsequent satisfaction and
               discharge of the 1941 Mortgage.

               (3)  Subdivision (9) of SECTION 6 of Article III of the
          Original Indenture is hereby amended to read as follows:

                    (9)  An Engineer's Certificate, made and dated not more
               than 10 days prior to the date of such application, stating
               that the signers have no knowledge of and do not believe
               that there have been, since the close of the period covered
               by the Engineer's Certificate specified in subdivision (3)
               above, Property Retirements in an amount which (after
               reduction of such amount by amounts of the character
               referred to in Clause (D) of subdivision 3 in respect of
               such Property Retirements) exceeds the amount of Property
               Additions since the close of such period by more than the
               amount of the Unapplied Balance of Property Additions
               calculated to be remaining upon the granting of the
               application (before any reduction of such Unapplied Balance
               of Property Additions by any amount of Net Property
               Additions applied to the withdrawal of cash deposited with
               the Trustee in connection with such Property Retirements).

               (4)  Subdivision (2) of SECTION 7 of Article III of the
          Original Indenture is hereby amended to read as follows:

                    (2)  A Treasurer's Certificate stating (a) that the
               Company is not to the best of the knowledge and belief of
               the signers in default under any of the provisions of this
               Indenture and (b) that Bonds theretofore authenticated an
               delivered under this Indenture, and/or bonds, theretofore
               authenticated and delivered under the 1941 Mortgage, of a
               specified aggregate principal amount (not less than the
               aggregate principal amount of Bonds for which such request
               for authentication and delivery is made under this SECTION)
               constitute Retired Bonds; and further stating that no part
               of such Retired Bonds has been theretofore made the basis
               under any of the provisions of this Indenture or the 1941
               Mortgage for the authentication and delivery of Bonds
               hereunder or bonds under the 1941 Mortgage, or the
               withdrawal of cash or the release of any property and that
               none of such Retired Bonds has been retired by the use of
               the proceeds of any insurance on any Funded Property (or
               "funded property" under the 1941 Mortgage) or the proceeds

               such fund or (y) bonds under SECTION 7 of Article III of the

               (6)  Subsection (d) of SECTION 8 of Article XIV of the
          Original Indenture is hereby amended adding at the end thereof
          the following:

               Any such request, demand, authorization, direction, notice,
               consent, waiver or other act, given or made as aforesaid,

                    Treasurer's Certificate stating the Company's intention
                    that, upon delivery of such Treasurer's Certificate,

          and the Holders of such Bonds or portions thereof shall
          nevertheless be no longer entitled to the benefit of the Lien of
          this Indenture or of any of the covenants of the Company under
          Article IV (except the covenants contained in SECTIONs 2, 3 and 4
          thereof) or any other covenants made in respect of such Bonds or
          portions thereof, but the indebtedness of the Company in respect

                         delivered to the 1998 Indenture Trustee as
                         the basis for the authentication and delivery
                         of securities under the 1998 Indenture which
                         remain outstanding thereunder, an `Event of

                         however, that, anything in this Indenture to

                         rescission and annulment of the consequences
                         thereof shall constitute a cure of the
                         corresponding default under Indenture and a
                         rescission and annulment of the consequences
                         thereof."

                          


                                                                 SCHEDULE D

                     PROSPECTIVE AMENDMENTS TO ORIGINAL INDENTURE

                    1.   The amendment of SECTION 2 of Article I of the
               Original Indenture to add thereto a definition of the term
               "fair value" substantially to the following effect:

                         "FAIR VALUE", with respect to property, means the
                    fair value of such property as may be determined by
                    reference to (a) the amount which would be likely to be
                    obtained in an arm's-length transaction with respect to
                    such property between an informed and willing buyer and
                    an informed and willing seller, under no compulsion,
                    respectively, to buy or sell, (b) the amount of
                    investment with respect to such property which,
                    together with a reasonable return thereon, would be
                    likely to be recovered through ordinary business
                    operations or otherwise, (c) the Cost, accumulated
                    depreciation and replacement cost with respect to such
                    property and/or (d) any other relevant factors;
                    provided, however, that (x) the fair value of property
                    shall be determined without deduction for any Prior
                    Liens on such property (except as otherwise provided in
                    clause (2) of subparagraph (C) of SECTION 3 of Article
                    VII and (y) the fair value to the Company of Property
                    Additions shall not reflect any reduction relating to
                    the fact that such Property Additions may be of less
                    value to a Person which is not the owner or operator of
                    the Mortgaged Property or any portion thereof than to a
                    Person which is such owner or operator.  Fair value may
                    be determined, without physical inspection, by the use
                    of accounting and engineering records and other data
                    maintained by the Company or otherwise available to the
                    Engineer certifying the same.

                    2.   The amendment of SECTION 2 of Article I of the
               Original Indenture to add thereto definitions of the terms
               "purchase money mortgage" and "purchase money obligations"
               substantially to the following effect:

                         "PURCHASE MONEY MORTGAGE" means, with respect to
                    any property being acquired or disposed of by the
                    Company or being released from the Lien of this
                    Indenture, a lien on such property which

                              (a) is taken or retained by the transferor of
                         such property to secure all or part of the
                         purchase price thereof;

                              (b) is granted to one or more Persons other
                         than the transferor which, by making advances or
                         incurring an obligation, give value to enable the
                         grantor of such lien to acquire rights in or the
                         use of such property;

                              (c)  is granted to any other Person in
                         connection with the release of such property from
                         the Lien of this Indenture on the basis of the
                         deposit with the Trustee or the trustee or other
                         holder of a Prior Lien  of obligations secured by
                         such lien on such property (as well as any other
                         property subject thereto);

                              (d) is held by a trustee or agent for the
                         benefit of one or more Persons described in clause
                         (a), (b) and/or (c) above, provided that such lien
                         may be held, in addition, for the benefit of one
                         or more other Persons which shall have theretofore
                         given, or may thereafter give, value to or for the
                         benefit or account of the grantor of such lien for
                         one or more other purposes; or

                              (e) otherwise constitutes a purchase money
                         mortgage or a purchase money security interest
                         under applicable law;

                    and, without limiting the generality of the foregoing,
                    for purposes of this Indenture, the term shall be
                    deemed to include any lien described above whether or
                    not such lien (x) shall permit the issuance or other
                    incurrence of additional indebtedness secured by such
                    lien on such property, (y) shall permit the subjection
                    to such lien of additional property and the issuance or
                    other incurrence of additional indebtedness on the
                    basis thereof and/or (z) shall have been granted prior
                    to the acquisition, disposition or release of such
                    property, shall attach to or otherwise cover property
                    other than the property being acquired, disposed of or
                    released and/or shall secure obligations issued prior
                    and/or subsequent to the issuance of the obligations
                    delivered in connection with such acquisition,
                    disposition or release.  The term "PURCHASE MONEY
                    OBLIGATION" shall mean an obligation secured by a
                    purchase money lien.

                    3.   The amendment of clause (b) in subdivision (1) of
               SECTION 9 of Article VII or the Original Indenture to read
               as follows:

                              (b)  in an amount equal to ten-sevenths
                         (10/7ths) of the principal amount of Bonds to the
                         authentication and delivery of which the Company
                         is entitled under the provisions of SECTION 7 of
                         Article III hereof.

                    4.   The amendment of subparagraph E in the first
               paragraph of SECTION 3 of Article VIII of the Original
               Indenture to:

                         (i)  to delete therefrom the second proviso or to
                    provide that the second proviso may be disregarded upon
                    specified conditions; or

                         (ii) to delete from the second proviso therein the
                    phrase "fifteen per centum (15%) of "; or

                         (iii)     to change the phrase "fifteen per centum
                    (15%)" in the second proviso therein to any higher

          Original Indenture to change the semi-colon at the end of clause

                   FIRST MORTGAGE BOND, COLLATERAL SERIES DUE 2008

                                  DUE AUGUST 1, 2008

               TUCSON ELECTRIC POWER COMPANY, a corporation of the State of
          Arizona (hereinafter sometimes called the Company), for value
          received, promises to pay to

          or registered assigns, the principal sum of               DOLLARS

          on August 1, 2008, in coin or currency of the United States of
          America which at the time of payment shall be legal tender for
          the payment of public and private debts, at the office or agency
          of the Company in The City of New York, or in the City of Tucson,
          Arizona, upon presentation hereof.  This Bond shall not bear
          interest.

               This bond is one of an issue of bonds of the Company, issued
          and to be issued in one or more series under and equally and
          ratably secured (except as any sinking, amortization,
          improvement, renewal or other fund, established in accordance
          with the provisions of the indenture hereinafter mentioned, may
          afford additional security for the bonds of any particular
          series) by the Indenture of Mortgage and Deed of Trust, dated as
          of December 1, 1992 (the "Original Indenture"), from the Company
          to Bank of Montreal Trust Company, trustee (the "Trustee"), as
          supplemented by various supplemental indentures including
          Supplemental Indenture No. 3, dated as of August 1, 1998 (the
          Original Indenture, as so supplemented, and such Supplemental
          Indenture being hereinafter called the "Indenture" and
          "Supplemental Indenture No. 3", respectively), to which Indenture
          reference is hereby made for a description of the property
          mortgaged and pledged, the nature and extent of the security
          provided by the Indenture, the rights and limitations of rights
          of the Company, the Trustee and the holders of said bonds with
          respect to the security provided by the Indenture, the powers,
          duties and immunities of the Trustee, the terms and conditions
          upon which such bonds are and are to be secured, and the
          circumstances under which additional bonds may be issued. 
          The acceptance of this bond shall be deemed to constitute the   
          consent and agreement by the holder hereof to all of the terms
          and provisions of the Indenture.  This bond is one of a series of
          bonds designated as the First Mortgage Bonds, Collateral Series
          due 2008, of the Company.

               The Indenture permits, with certain exceptions as therein
          provided, the Trustee to enter into one or more supplemental
          indentures for the purpose of adding any provisions to, or
          changing in any manner or eliminating any of the provisions of,
          the Indenture with the consent of the holders of not less than
          sixty per centum (60%) in aggregate principal amount of the bonds
          of all series then outstanding under the Indenture, considered as
          one class; provided, however, that if there shall be bonds of
          more than one series outstanding under the Indenture and if a
          proposed supplemental indenture shall directly affect the rights
          of the holders of bonds of one or more, but less than all, of
          such series, then the consent only of the holders of bonds in
          aggregate principal amount of the outstanding bonds of all series
          so directly affected, considered as one class, shall be required;
          and provided, further, that if the bonds of any series shall have
          been issued in more than one tranche and if the proposed
          supplemental indenture shall directly affect the rights of the
          holder of bonds of one or more, but less than all, of such
          tranches, then the consent only of the holders of bonds in
          aggregate principal amount of the outstanding bonds of all
          tranches so directly affected, considered as one class, shall be
          required; and provided, further, that the Indenture permits the
          Trustee to enter into one or more supplemental indentures for
          limited purposes without the consent of any holders of bonds. 
          Any such consent by the holder of this bond shall be conclusive
          and binding upon such holder and upon all future holders of this
          bond and of any bond issued upon the registration of transfer
          hereof or in exchange therefor or in lieu hereof, whether or not
          notation of such consent is made upon this bond.  The holders of
          this bond shall be deemed to have consented to certain amendments
          to the Indenture which are specified in Supplemental Indenture
          No. 3.

               The bonds of this series are being issued and delivered by
          the Company to Bank of Montreal Trust Company, as trustee under
          the Indenture, dated as of August 1, 1998, as supplemented (the
          "1998 Indenture"), of the Company to such trustee (the "1998
          Indenture Trustee"), in exchange for other obligations of the
          Company which have heretofore been delivered to the 1998
          Indenture Trustee, as the basis for the authentication and
          delivery of securities under the 1998 Indenture.  As provided in
          the 1998 Indenture, the bonds of this series are to be registered
          in the name of the 1998 Indenture Trustee or its nominee and will
          be owned and held by the 1998 Indenture Trustee, subject to the
          provisions of the 1998 Indenture, for the benefit of the holders
          of all securities from time to time outstanding under the 1998
          Indenture, and the Company shall have no interest therein.  The
          bonds of this series shall not be transferable except as required
          to effect transfer to any successor trustee under the 1998
          Indenture.

               Anything herein to the contrary notwithstanding, any payment
          by the Company under the 1998 Indenture of the principal of the
          securities which shall have been authenticated and delivered
          under the 1998 Indenture on the basis of the delivery to the 1998
          Indenture Trustee of bonds of this series (other than by the
          application of the proceeds of a payment in respect of such bonds
          of this series) shall, to the extent thereof, be deemed to
          satisfy and discharge the obligation of the Company, if any, to
          make a payment of principal of such bonds of this series which is
          then due.

               The bonds of this series are redeemable prior to maturity at
          the option of the Company, as a whole at any time or in part from
          time to time, at the principal amount of bonds so to be redeemed.


               Notice of redemption shall be given by mail to the holders
          of bonds of this series, not less than 30 nor more than 60 days
          prior to the redemption date.  As provided in the Indenture,
          notice of redemption may state that such redemption shall be
          conditional upon the receipt by the Trustee, on or prior to the
          date fixed for redemption, of money sufficient to pay the
          principal of this bond; a notice of redemption so conditioned
          shall be of no force or effect if such money is not so received
          and, in such event, the Company shall not be required to redeem
          this bond.

               In the event of redemption of this bond in part only, a new
          bond or bonds of this series, of like tenor, for the unredeemed
          portion hereof will be issued to the holder hereof upon the
          surrender hereof.

               The principal of this bond may become or be declared due and
          payable before the stated maturity hereof, on the conditions, in
          the manner and at the times set forth in the Indenture, upon the
          happening of a default as therein provided.

               This bond is non-transferable except as required to effect
          transfer to any successor trustee under the 1998 Indenture, any
          such transfer to be registered at the office or agency of the
          Company in The City of New York, upon surrender of this bond by
          the registered owner hereof or by attorney authorized in writing,
          and upon any such registration of transfer a new bond of this
          series, for the same aggregate principal amount and having the
          same stated maturity date, will be issued to the transferee in
          exchange herefor.  Prior to due presentment for registration of
          transfer, the Company and the Trustee may deem and treat the
          person in whose name this bond is registered as the absolute
          owner hereof for the purpose of receiving payment and for all
          other purposes.  This bond, alone or with other bonds of this
          series, may in like manner be exchanged at such office or agency
          for one or more bonds of this series of the same aggregate
          principal amount and having the same stated maturity date and
          interest rate, all as provided in the Indenture.

               As provided in the Indenture and subject to certain
          limitations therein set forth, this Bond or any portion of the
          principal amount hereof will be deemed to have been paid for all
          purposes of the Indenture and to be no longer Outstanding
          thereunder, and the Company's entire indebtedness in respect
          thereof will be deemed to have been satisfied and discharged, if
          there has been irrevocably deposited with the Trustee or any
          Paying Agent (other than the Company), in trust, money in an
          amount which will be sufficient, and/or Government Obligations,
          the principal of and interest on which when due, without regard
          to any reinvestment thereof, will provide moneys which, together
          with moneys so deposited, will be sufficient, to pay when due the
          principal of and interest on this bond when due.

               No recourse shall be had for the payment of the principal of
          or interest on this bond, or for any claim based hereon or
          otherwise in respect hereof or of the Indenture, against any
          incorporator, shareholder, director or officer, as such, past,
          present or future, of the Company or of any predecessor or
          successor corporation, either directly or through the Company or
          any predecessor or successor corporation, whether by virtue of
          any constitution, statute or rule of law, or by the enforcement
          of any assessment or penalty or by any legal or equitable
          proceeding or otherwise howsoever (including, without limiting
          the generality of the foregoing, any proceeding to enforce any
          claimed liability of shareholders of the Company, based upon any
          theory of disregarding the corporate entity of the Company or
          upon any theory that the Company was acting as the agent or
          instrumentality of the shareholders); all such liability being,
          by the acceptance hereof and as a part of the consideration for
          the issuance hereof, expressly waived and released by every
          holder hereof, and being likewise waived and released by the
          terms of the Indenture under which this bond is issued, as more
          fully provided in said Indenture.

               This bond shall not be valid or become obligatory for any
          purpose until the certificate of authentication hereon shall have
          been signed by Bank of Montreal Trust Company, or its successor,
          as Trustee under the Indenture.

               IN WITNESS WHEREOF, the Company has caused this bond to be
          signed in its name by the manual or facsimile signature of its
          President or one of its Vice Presidents, and its corporate seal,
          or a facsimile thereof, to be impressed or imprinted hereon and
          attested by the manual by the manual or facsimile signature of   
          its Secretary or one of its Assistant Secretaries.

          Trustee to take any action under any provision of this Indenture,
          the Company shall furnish to the Trustee an Officer's Certificate
          stating that all conditions precedent, if any, provided for in
          this Indenture relating to the proposed action have been complied
          with and an Opinion of Counsel stating that in the opinion of
          such counsel all such conditions precedent, if any, have been
          complied with, it being understood that in the case of any such
          application or request as to which the furnishing of such
          documents is specifically required by any provision of this
          Indenture relating to such particular application or request, no
          additional certificate or opinion need be furnished.

                    Every certificate or opinion with respect to compliance
          with a condition or covenant provided for in this Indenture shall
          include:

                         (a)  a statement that each individual signing such
                    certificate or opinion has read such covenant or
                    condition and the definitions herein relating thereto;

                         (b)  a brief statement as to the nature and scope
                    of the examination or investigation upon which the

                    individual, such individual has made such examination
                    or investigation as is necessary to enable such
                    individual to express an informed opinion as to whether
                    or not such covenant or condition has been complied
                    with; and

                         (d)  a statement as to whether, in the opinion of
                    each such individual, such condition or covenant has
                    been complied with.

          SECTION 103.  CONTENT AND FORM OF DOCUMENTS DELIVERED TO TRUSTEE.

                    (a)  Any Officer's Certificate may be based (without
          further examination or investigation), insofar as it relates to
          or is dependent upon legal matters, upon an opinion of, or
          representations by, counsel, unless, in any case, such officer
          has actual knowledge that the certificate or opinion or
          representations with respect to the matters upon which such
          Officer's Certificate may be based as aforesaid are erroneous.

                    Any Opinion of Counsel may be based (without further
          examination or investigation), insofar as it relates to or is
          dependent upon factual matters, information with respect to which
          is in the possession of the Company, upon a certificate of, or
          representations by, an officer or officers of the Company, unless
          such counsel has actual knowledge that the certificate or opinion
          or representations with respect to the matters upon which his
          opinion may be based as aforesaid are erroneous.  In addition,
          any Opinion of Counsel may be based (without further examination
          or investigation), insofar as it relates to or is dependent upon
          matters covered in an Opinion of Counsel rendered by other
          counsel, upon such other Opinion of Counsel, unless such counsel
          has actual knowledge that the Opinion of Counsel rendered by such
          other counsel with respect to the matters upon which his Opinion
          of Counsel may be based as aforesaid are erroneous.  If, in order
          to render any Opinion of Counsel provided for herein, the signer
          thereof shall deem it necessary that additional facts or matters
          be stated in any Officer's Certificate provided for herein, then
          such certificate may state all such additional facts or matters
          as the signer of such Opinion of Counsel may request.  

                    (b)  In any case where several matters are required to
          be certified by, or covered by an opinion of, any specified
          Person, it is not necessary that all such matters be certified
          by, or covered by the opinion of, only one such Person, or that
          they be so certified or covered by only one document, but one
          such Person may certify or give an opinion with respect to some
          matters and one or more other such Persons as to other matters,
          and any such Person may certify or give an opinion as to such
          matters in one or several documents.  Where any Person is
          required to make, give or execute two or more applications,
          requests, consents, certificates, statements, opinions or other
          instruments under this Indenture, they may, but need not, be
          consolidated and form one instrument.

                    (c)  Whenever, subsequent to the receipt by the Trustee
          of any Board Resolution, Officer's Certificate, Opinion of
          Counsel or other document or instrument, a clerical,
          typographical or other inadvertent or unintentional error or
          omission shall be discovered therein, a new document or
          instrument may be substituted therefor in corrected form with the
          same force and effect as if originally filed in the corrected
          form and, irrespective of the date or dates of the actual
          execution and/or delivery thereof, such substitute document or
          instrument shall be deemed to have been executed and/or delivered
          as of the date or dates required with respect to the document or
          instrument for which it is substituted.  Anything in this
          Indenture to the contrary notwithstanding, if any such corrective
          document or instrument indicates that action has been taken by or
          at the request of the Company which could not have been taken had
          the original document or instrument not contained such error or
          omission, the action so taken shall not be invalidated or
          otherwise rendered ineffective but shall be and remain in full
          force and effect, except to the extent that such action was a
          result of willful misconduct or bad faith.  Without limiting the
          generality of the foregoing, any Securities issued under the
          authority of such defective document or instrument shall
          nevertheless be the valid obligations of the Company entitled to
          the benefits provided by this Indenture equally and ratably with
          all other Outstanding Securities, except as aforesaid.

          SECTION 104.  ACTS OF HOLDERS.

                    (a)  Any request, demand, authorization, direction,
          notice, consent, election, waiver or other action provided by
          this Indenture to be made, given or taken by Holders may be
          embodied in and evidenced by one or more instruments of
          substantially similar tenor signed by such Holders in person or
          by an agent duly appointed in writing or, alternatively, may be
          embodied in and evidenced by the record of Holders voting in
          favor thereof, either in person or by proxies duly appointed in
          writing, at any meeting of Holders duly called and held in
          accordance with the provisions of Article Twelve, or a
          combination of such instruments and any such record.  Except as
          herein otherwise expressly provided, such action shall become
          effective when such instrument or instruments or record or both
          are delivered to the Trustee and, where it is hereby expressly
          required, to the Company.  Such instrument or instruments and any
          such record (and the action embodied therein and evidenced
          thereby) are herein sometimes referred to as the "Act" of the
          Holders signing such instrument or instruments and so voting at
          any such meeting.  Proof of execution of any such instrument or
          of a writing appointing any such agent, or of the holding by any
          Person of a Security, shall be sufficient for any purpose of this
          Indenture and (subject to Section 801) conclusive in favor of the
          Trustee and the Company, if made in the manner provided in this
          Section.  The record of any meeting of Holders shall be proved in
          the manner provided in Section 1206.

                    (b)  The fact and date of the execution by any Person
          of any such instrument or writing may be proved by the affidavit
          of a witness of such execution or by a certificate of a notary
          public or other officer authorized by law to take acknowledgments
          of deeds, certifying that the individual signing such instrument
          or writing acknowledged to him the execution thereof or may be
          proved in any other manner which the Trustee and the Company deem
          sufficient.  Where such execution is by a signer acting in a
          capacity other than his individual capacity, such certificate or
          affidavit shall also constitute sufficient proof of his
          authority.

                    (c)  The ownership of Securities, the principal amount
          (except as otherwise contemplated in clause (y) of the first
          proviso to the definition of Outstanding) and serial numbers of
          Securities held by any Person, and the date of holding the same,
          shall be proved by the Security Register.

                    (d)  Any request, demand, authorization, direction,
          notice, consent, election, waiver or other Act of a Holder shall
          bind every future Holder of the same Security and the Holder of
          every Security issued upon the registration of transfer thereof
          or in exchange therefor or in lieu thereof in respect of anything
          done, omitted or suffered to be done by the Trustee or the
          Company in reliance thereon, whether or not notation of such
          action is made upon such Security.

                    (e)  Until such time as written instruments shall have
          been delivered to the Trustee with respect to the requisite
          percentage of principal amount of Securities for the action
          contemplated by such instruments, any such instrument executed
          and delivered by or on behalf of a Holder may be revoked with
          respect to any or all of such Securities by written notice by
          such Holder or any subsequent Holder, proven in the manner in
          which such instrument was proven.

                    (f)  Securities of any series, or any Tranche thereof,
          authenticated and delivered after any Act of Holders may, and
          shall if required by the Trustee, bear a notation in form
          approved by the Trustee as to any action taken by such Act of
          Holders.  If the Company shall so determine, new Securities of
          any series, or any Tranche thereof, so modified as to conform, in
          the opinion of the Trustee and the Company, to such action may be
          prepared and executed by the Company and authenticated and
          delivered by the Trustee in exchange for Outstanding Securities
          of such series or Tranche.

                    (g)  The Company may, at its option, by Company Order,
          fix in advance a record date for the determination of Holders
          entitled to give any request, demand, authorization, direction,
          notice, consent, waiver or other Act solicited by the Company,
          but the Company shall have no obligation to do so; provided,
          however, that the Company may not fix a record date for the
          giving or making of any notice, declaration, request or direction
          referred to in the next sentence.  In addition, the Trustee may,
          at its option, fix in advance a record date for the determination
          of Holders of Securities of any series entitled to join in the
          giving or making of any Notice of Default, any declaration of
          acceleration referred to in Section 702, any request to institute
          proceedings referred to in Section 707 or any direction referred
          to in Section 712, in each case with respect to Securities of
          such series.  If any such record date is fixed, such request,
          demand, authorization, direction, notice, consent, waiver or
          other Act, or such notice, declaration, request or direction, may
          be given before or after such record date, but only the Holders
          of record at the close of business on the record date shall be
          deemed to be Holders for the purposes of determining (i) whether
          Holders of the requisite proportion of the Outstanding Securities
          have authorized or agreed or consented to such Act (and for that
          purpose the Outstanding Securities shall be computed as of the
          record date) and/or (ii) which Holders may revoke any such Act
          (notwithstanding subsection (e) of this Section); and any such
          Act, given as aforesaid, shall be effective whether or not the
          Holders which authorized or agreed or consented to such Act
          remain Holders after such record date and whether or not the
          Securities held by such Holders remain Outstanding after such
          record date.

          SECTION 105.  NOTICES, ETC. TO TRUSTEE AND COMPANY.

                    Any request, demand, authorization, direction, notice,
          consent, election, waiver or Act of Holders or other document
          provided or permitted by this Indenture to be made upon, given or
          furnished to, or filed with, the Trustee by any Holder or by the
          Company, or the Company by the Trustee or by any Holder, shall be
          sufficient for every purpose hereunder (unless otherwise
          expressly provided herein) if the same shall be in writing and
          delivered personally to an officer or other responsible employee
          of the addressee, or transmitted by facsimile transmission, telex
          or other direct written electronic means to such telephone number

          below or to such other address as either party hereto may from
          time to time designate:

                         If to the Trustee, to:

                              Bank of Montreal Trust Company
                              88 Pine Street
                              New York, New York  10005

                              Attention:  Corporate Trust Department
                              Telephone:  (212) 701-7650
                              Facsimile:  (212) 701-7664

                         If to the Company, to:

                              Tucson Electric Power Company
                              220 West Sixth Street
                              Tucson, Arizona  85702
                              Attention:  Treasurer
                              Telephone:  (520) 884-3660
                              Facsimile:  (520) 884-3888


                    Any communication contemplated herein shall be deemed
          to have been made, given, furnished and filed if personally
          delivered, on the date of delivery, if transmitted by facsimile
          transmission, telex or other direct written electronic means, on
          the date of transmission, and if transmitted by registered mail,
          on the date of receipt.

          SECTION 106.  NOTICE TO HOLDERS OF SECURITIES; WAIVER.

                    Except as otherwise expressly provided herein, where
          this Indenture provides for notice to Holders of any event, such
          notice shall be sufficiently given, and shall be deemed given, to
          Holders if in writing and mailed, first-class postage prepaid, to
          each Holder affected by such event, at the address of such Holder
          as it appears in the Security Register, not later than the latest
          date, and not earlier than the earliest date, prescribed for the
          giving of such notice.

                    In case by reason of the suspension of regular mail
          service or by reason of any other cause it shall be impracticable
          to give such notice to Holders by mail, then such notification as
          shall be made with the approval of the Trustee shall constitute a
          sufficient notification for every purpose hereunder.  In any case
          where notice to Holders is given by mail, neither the failure to
          mail such notice, nor any defect in any notice so mailed, to any
          particular Holder shall affect the sufficiency of such notice
          with respect to other Holders.

                    Any notice required by this Indenture may be waived in
          writing by the Person entitled to receive such notice, either
          before or after the event otherwise to be specified therein, and
          such waiver shall be the equivalent of such notice.  Waivers of
          notice by Holders shall be filed with the Trustee, but such
          filing shall not be a condition precedent to the validity of any
          action taken in reliance upon such waiver.

          SECTION 107.  CONFLICT WITH TRUST INDENTURE ACT.

                    If any provision of this Indenture limits, qualifies or
          conflicts with another provision hereof which is required or
          deemed to be included in this Indenture by, or is otherwise
          governed by, any provision of the Trust Indenture Act, such other
          provision shall control; and if any provision hereof otherwise
          conflicts with the Trust Indenture Act, the Trust Indenture Act

                    In any case where any Interest Payment Date, Redemption

          provision of this Indenture or of the Securities other than a

          Tranche thereof, or in the indenture supplemental hereto, Board
          Resolution or Officer's Certificate which establishes the terms
          of the Securities of such series or Tranche) payment of interest

          of Payment on such date, but may be made on the next succeeding
          Business Day at such Place of Payment with the same force and
          effect as if made on the Interest Payment Date or Redemption

          on the amount so payable for the period from and after such
          Interest Payment Date, Redemption Date or Stated Maturity, as the
          case may be, to such Business Day.

          SECTION 114.  INVESTMENT OF CASH HELD BY TRUSTEE.

                    Any cash held by the Trustee or any Paying Agent under
          any provision of this Indenture shall, at the request of the
          Company evidenced by Company Order, be invested or reinvested in
          Investment Securities designated by the Company (such Company
          Order to contain a representation to the effect that the
          securities designated therein constitute Investment Securities),
          and any interest on such Investment Securities shall be promptly
          paid over to the Company as received free and clear of any Lien. 
          Such Investment Securities shall be held subject to the same
          provisions hereof as the cash used to purchase the same, but upon
          a like request of the Company shall be sold, in whole or in
          designated part, and the proceeds of such sale shall be held
          subject to the same provisions hereof as the cash used to
          purchase the Investment Securities so sold.  If such sale shall
          produce a net sum less than the cost of the Investment Securities
          so sold, the Company shall pay to the Trustee or any such Paying
          Agent, as the case may be, such amount in cash as, together with
          the net proceeds from such sale, shall equal the cost of the
          Investment Securities so sold, and if such sale shall produce a
          net sum greater than the cost of the Investment Securities so
          sold, the Trustee or any such Paying Agent, as the case may be,
          shall promptly pay over to the Company an amount in cash equal to
          such excess, free and clear of any Lien.  In no event shall the
          Trustee be liable for any loss incurred in connection with the
          sale of any Investment Security pursuant to this Section.

                    Notwithstanding the foregoing, if an Event of Default
          shall have occurred and be continuing, interest on Investment
          Securities and any gain upon the sale thereof shall be held, in
          trust, until such Event of Default shall have been cured or
          waived, whereupon such interest and gain shall be promptly paid
          over to the Company free and clear of any Lien.

                    determined (to the extent not established pursuant to
                    clause (e) of this paragraph);

                         (n)  if other than the principal amount thereof,
                    the portion of the principal amount of Securities of
                    such series, or any Tranche thereof, which shall be
                    payable upon declaration of acceleration of the
                    Maturity thereof pursuant to Section 702;

                         (o)  the terms, if any, pursuant to which the
                    Securities of such series, or any Tranche thereof, may
                    be converted into or exchanged for shares of capital
                    stock or other securities of the Company or any other
                    Person;

                         (p)  the obligations or instruments, if any, which
                    shall be considered to be Eligible Obligations in
                    respect of the Securities of such series, or any
                    Tranche thereof, denominated in a currency other than
                    Dollars or in a composite currency, and any additional
                    or alternative provisions for the reinstatement of the
                    Company's indebtedness in respect of such Securities
                    after the satisfaction and discharge thereof as
                    provided in Section 601;

                         (q)  if the Securities of such series, or any
                    Tranche thereof, are to be issued in global form, (i)
                    any limitations on the rights of the Holder or Holders
                    of such Securities to transfer or exchange the same or
                    to obtain the registration of transfer thereof, (ii)
                    any limitations on the rights of the Holder or Holders
                    thereof to obtain certificates therefor in definitive
                    form in lieu of temporary form and (iii) any and all
                    other matters incidental to such Securities;

                         (r)  if the Securities of such series, or any
                    Tranche thereof, are to be issuable as bearer
                    securities, any and all matters incidental thereto
                    which are not specifically addressed in a supplemental
                    indenture as contemplated by clause (f) of Section
                    1101;

                         (s)  to the extent not established pursuant to
                    clause (q) of this paragraph, any limitations on the
                    rights of the Holders of the Securities of such Series,
                    or any Tranche thereof, to transfer or exchange such
                    Securities or to obtain the registration of transfer
                    thereof; and if a service charge will be made for the
                    registration of transfer or exchange of Securities of
                    such series, or any Tranche thereof, the amount or
                    terms thereof;

                         (t)  any exceptions to Section 113, or variation
                    in the definition of Business Day, with respect to the
                    Securities of such series, or any Tranche thereof; and

                         (u)  any other terms of the Securities of such
                    series, or any Tranche thereof.

                    With respect to Securities of a series subject to a
          Periodic Offering, the Officer's Certificate, the indenture
          supplemental hereto or the Board Resolution which establishes
          such series, as the case may be, may provide general terms or
          parameters for Securities of such series and provide either that
          the specific terms of Securities of such series, or any Tranche
          thereof, shall be specified in a Company Order or that such terms
          shall be determined by the Company or its agents in accordance
          with procedures specified in a Company Order as contemplated by
          clause (b) of Section 303.

                    Unless otherwise specified with respect to a series of
          Securities pursuant to Section 301(b), any limit upon the
          aggregate principal amount of a series of Securities may be
          increased without the consent of any Holders and additional
          Securities of such series may be authenticated and delivered up
          to the limit upon the aggregate principal amount authorized with
          respect to such series as so increased.

                    Anything herein to the contrary notwithstanding, the
          Trustee shall be under no obligation to authenticate and deliver
          Securities of any series the terms of which, established as
          contemplated by this Section, would affect the rights, duties,
          obligations, liabilities or immunities of the Trustee under this
          Indenture or otherwise.

          SECTION 302.  DENOMINATIONS.

                    Unless otherwise provided as contemplated by Section
          301 with respect to any series of Securities, or any Tranche
          thereof, the Securities of each series shall be issuable in
          denominations of One Thousand Dollars ($1,000) and any integral
          multiple thereof.

          SECTION 303.  EXECUTION, DATING, CERTIFICATE OF AUTHENTICATION.

                    Unless otherwise provided as contemplated by Section
          301 with respect to any series of Securities, or any Tranche
          thereof, the Securities shall be executed on behalf of the
          Company by an Authorized Officer, and may have the corporate seal
          of the Company affixed thereto or reproduced thereon and attested
          by any other Authorized Officer.  The signature of any or all of
          these officers on the Securities may be manual or facsimile.

                    Securities bearing the manual or facsimile signatures
          of individuals who were at the time of execution Authorized
          Officers of the Company shall bind the Company, notwithstanding
          that such individuals or any of them have ceased to hold such
          offices prior to the authentication and delivery of such
          Securities or did not hold such offices at the date of such
          Securities.

                    The Trustee shall authenticate and deliver Securities
          of a series, for original issue, at one time or from time to time
          in accordance with the Company Order referred to below, upon
          receipt by the Trustee of:

                         (a)  the instrument or instruments establishing
                    the form or forms and terms of such series, as provided
                    in Sections 201 and 301;

                         (b)  a Company Order requesting the authentication
                    and delivery of such Securities and, to the extent that
                    the terms of such Securities shall not have been
                    established in an Officer's Certificate, an indenture
                    supplemental hereto or a Board Resolution, all as
                    contemplated by Sections 201 and 301, either (i)
                    establishing such terms or (ii) in the case of
                    Securities of a series subject to a Periodic Offering,
                    specifying procedures, acceptable to the Trustee, by
                    which such terms are to be established (which
                    procedures may provide for authentication and delivery
                    pursuant to oral or electronic instructions from the
                    Company or any agent or agents thereof, which oral
                    instructions are to be promptly confirmed
                    electronically or in writing), in either case in
                    accordance with the instrument or instruments delivered
                    pursuant to clause (a) above;

                         (c)  Securities of such series, executed on behalf
                    of the Company by an Authorized Officer; 

                         (d)  an Opinion of Counsel to the effect that:

                              (i)  the form or forms of such Securities
                         have been duly authorized by the Company and have
                         been established in conformity with the provisions
                         of this Indenture;

                              (ii) the terms of such Securities have been
                         duly authorized by the Company and have been
                         established in conformity with the provisions of
                         this Indenture; and

                              (iii)     when such Securities shall have
                         been authenticated and delivered by the Trustee
                         and issued and delivered by the Company in the
                         manner and subject to any conditions specified in
                         such Opinion of Counsel, such Securities will
                         constitute valid obligations of the Company,
                         entitled to the benefits provided by this
                         Indenture;

                    provided, however, that, with respect to Securities of
                    a series subject to a Periodic Offering, the Trustee
                    shall be entitled to receive such Opinion of Counsel
                    only once at or prior to the time of the first
                    authentication and delivery of such Securities
                    (provided that such Opinion of Counsel addresses the
                    authentication and delivery of all Securities of such
                    series) and that, in lieu of the opinions described in
                    clauses (ii) and (iii) above, Counsel may opine that: 

                              (x)  when the terms of such Securities shall
                         have been established pursuant to a Company Order
                         or Orders or pursuant to such procedures as may be
                         specified from time to time by a Company Order or
                         Orders, all as contemplated by and in accordance
                         with the instrument or instruments delivered
                         pursuant to clause (a) above, such terms will have
                         been duly authorized by the Company and will have
                         been established in conformity with the provisions
                         of this Indenture; and

                              (y)  when such Securities shall have been
                         authenticated and delivered by the Trustee in
                         accordance with this Indenture and the Company
                         Order or Orders or the specified procedures
                         referred to in paragraph (x) above and issued and
                         delivered by the Company in the manner and subject
                         to any conditions specified in such Opinion of
                         Counsel, such Securities will constitute valid
                         obligations of the Company, entitled to the
                         benefits provided by this Indenture; and

                         (e)  so long as the Collateral Release Date shall
                    not have occurred, the Class A Bond and documents
                    specified in Section 312.

                    With respect to Securities of a series subject to a
          Periodic Offering, the Trustee may conclusively rely, as to the
          authorization by the Company of any of such Securities, the forms
          and terms thereof, the validity thereof and the compliance of the
          authentication and delivery thereof with the terms and conditions
          of this Indenture, upon the Opinion or Opinions of Counsel and
          the certificates and other documents delivered pursuant to this
          Article at or prior to the time of the first authentication and
          delivery of Securities of such series until any of such opinions,
          certificates or other documents have been superseded or revoked
          or expire by their terms.  In connection with the authentication
          and delivery of Securities of a series subject to a Periodic
          Offering, the Trustee shall be entitled to assume that the
          Company's instructions to authenticate and deliver such
          Securities do not violate any applicable law or any applicable
          rule, regulation or order of any Governmental Authority having
          jurisdiction over the Company.

                    If the form of terms of the Securities of any series
          have been established by or pursuant to a Board Resolution or an
          Officer's Certificate as permitted by Sections 201 or 301, the
          Trustee shall not be required to authenticate such Securities if
          the issuance of such Securities pursuant to this Indenture will
          affect the Trustee's own rights, duties or immunities under the
          Securities and this Indenture or otherwise in a manner which is
          not reasonably acceptable to the Trustee.

                    Unless otherwise specified as contemplated by Section
          301 with respect to any series of Securities, or any Tranche
          thereof, each Security shall be dated the date of its
          authentication.

                    Unless otherwise specified as contemplated by Section
          301 with respect to any series of Securities, or any Tranche
          thereof, no Security shall be entitled to any benefit under this
          Indenture or be valid or obligatory for any purpose unless there
          appears on such Security a certificate of authentication
          substantially in the form provided for herein executed by the
          Trustee or an Authenticating Agent by manual signature of an
          authorized officer thereof, and such certificate upon any
          Security shall be conclusive evidence, and the only evidence,
          that such Security has been duly authenticated and delivered
          hereunder and is entitled to the benefits of this Indenture. 
          Notwithstanding the foregoing, if (a) any Security shall have
          been authenticated and delivered hereunder to the Company, or any
          Person acting on its behalf, but shall never have been issued and
          sold by the Company, (b) the Company shall deliver such Security
          to the Security Registrar for cancellation or shall cancel such
          Security and deliver evidence of such cancellation to the
          Trustee, in each case as provided in Section 309, and (c) the
          Company, at its election, shall deliver to the Trustee a written
          statement (which need not comply with Section 102 and need not be
          accompanied by an Officer's Certificate or an Opinion of Counsel)
          stating that such Security has never been issued and sold by the
          Company, then, for all purposes of this Indenture, such Security
          shall be deemed never to have been authenticated and delivered
          hereunder and shall never be entitled to the benefits hereof.

          SECTION 304.  TEMPORARY SECURITIES.

                    Pending the preparation of definitive Securities of any
          series, or any Tranche thereof, the Company may execute, and upon
          Company Order the Trustee shall authenticate and deliver,
          temporary Securities which are printed, lithographed,
          typewritten, mimeographed, photocopied or otherwise produced, in
          any authorized denomination, substantially of the tenor of the
          definitive Securities in lieu of which they are issued, with such
          appropriate insertions, omissions, substitutions and other
          variations as the officers executing such Securities may
          determine, as evidenced by their execution of such Securities;
          provided, however, that temporary Securities need not recite
          specific redemption, sinking fund, conversion or exchange
          provisions.

                    Except as otherwise specified as contemplated by
          Section 301 with respect to the Securities of any series, or any
          Tranche thereof, after the preparation of definitive Securities
          of such series or Tranche, the temporary Securities of such
          series or Tranche shall be exchangeable, without charge to the
          Holder thereof, for definitive Securities of such series or
          Tranche upon surrender of such temporary Securities at the office
          or agency of the Company maintained pursuant to Section 502 in a
          Place of Payment for such Securities.  Upon such surrender of
          temporary Securities, the Company shall, except as aforesaid,
          execute and the Trustee shall authenticate and deliver in
          exchange therefor definitive Securities of the same series and
          Tranche, of authorized denominations and of like tenor and
          aggregate principal amount.

                    Until exchanged in full as hereinabove provided,
          temporary Securities shall in all respects be entitled to the
          same benefits under this Indenture as definitive Securities of
          the same series and Tranche and of like tenor authenticated and
          delivered hereunder.

          SECTION 305.  REGISTRATION, REGISTRATION OF TRANSFER AND
          EXCHANGE.

                    The Company shall cause to be kept in one of the
          offices designated pursuant to Section 502, with respect to the
          Securities of each series, or any Tranche thereof, a register
          (the "SECURITY REGISTER") in which, subject to such reasonable
          regulations as it may prescribe, the Company shall provide for
          the registration of Securities of such series or Tranche and the
          registration of transfer thereof.  The Company shall designate
          one Person to maintain the Security Register for the Securities
          of each series and such Person is referred to herein, with
          respect to such series, as the "SECURITY REGISTRAR".  Anything
          herein to the contrary notwithstanding, the Company may designate
          one or more of its offices as an office in which a register with
          respect to the Securities of one or more series, or any Tranche
          or Tranches thereof, shall be maintained, and the Company may
          designate itself the Security Registrar with respect to one or
          more of such series.  The Security Register shall be open for
          inspection by the Trustee and the Company at all reasonable
          times.

                    Except as otherwise specified as contemplated by
          Section 301 with respect to the Securities of any series, or any
          Tranche thereof, upon presentment for registration of transfer of
          any Security of such series or Tranche at the office or agency of
          the Company maintained pursuant to Section 502 in a Place of
          Payment for such series or Tranche, and further upon satisfaction
          of any conditions prescribed by applicable law, the Company shall
          execute, and the Trustee shall authenticate and deliver, in the
          name of the designated transferee or transferees, one or more new
          Securities of the same series and Tranche, of authorized
          denominations and of like tenor and aggregate principal amount.

                    Except as otherwise specified as contemplated by
          Section 301 with respect to the Securities of any series, or any
          Tranche thereof, any Security of such series or Tranche may be
          exchanged at the option of the Holder, for one or more new
          Securities of the same series and Tranche, of authorized
          denominations and of like tenor and aggregate principal amount,
          upon presentment of the Securities to be exchanged at any such
          office or agency.  Whenever any Securities are so presented for
          exchange, and upon satisfaction of any conditions prescribed by
          applicable law, the Company shall execute, and the Trustee shall
          authenticate and deliver, the Securities which the Holder making
          the exchange is entitled to receive.

                    All Securities delivered upon any registration of
          transfer or exchange of Securities shall be valid obligations of
          the Company, evidencing the same debt, and entitled to the same
          benefits under this Indenture, as the Securities presented upon
          such registration of transfer or exchange.

                    Every Security presented for registration of transfer
          or for exchange shall (if so required by the Company, the Trustee
          or the Security Registrar) be duly endorsed or shall be
          accompanied by a written instrument of transfer in form
          satisfactory to the Company, the Trustee or the Security
          Registrar, as the case may be, duly executed by the Holder
          thereof or his attorney duly authorized in writing.

                    Unless otherwise specified as contemplated by Section
          301 with respect to Securities of any series, or any Tranche
          thereof, no service charge shall be made for any registration of
          transfer or exchange of Securities, but the Company may require
          payment of a sum sufficient to cover any tax or other
          governmental charge that may be imposed in connection with any
          registration of transfer or exchange of Securities, other than
          exchanges pursuant to Section 304, 406 or 1106 not involving any
          transfer.

                    The Company shall not be required to execute or to
          provide for the registration of transfer of or the exchange of
          (a) Securities of any series, or any Tranche thereof, during a
          period of fifteen (15) days immediately preceding the date notice
          is to be given identifying the serial numbers of the Securities
          of such series or Tranche called for redemption or (b) any
          Security so selected for redemption in whole or in part, except
          the unredeemed portion of any Security being redeemed in part.

          SECTION 306.  MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

                    If any mutilated Security is presented to the Trustee,
          the Company shall execute and the Trustee shall authenticate and
          deliver in exchange therefor a new Security of the same series
          and Tranche, and of like tenor and principal amount and bearing a
          number not contemporaneously outstanding.

                    If there shall be delivered to the Company and the
          Trustee (a) evidence to their satisfaction of the ownership of
          and the destruction, loss or theft of any Security and (b) such
          security or indemnity as may be reasonably required by them to
          save each of them and any agent of either of them harmless, then,
          in the absence of notice to the Company or the Trustee that such
          Security is held by a Person deemed to be a protected purchaser
          under applicable law, the Company shall execute and the Trustee
          shall authenticate and deliver, in lieu of any such destroyed,
          lost or stolen Security, a new Security of the same series and
          Tranche, and of like tenor and principal amount and bearing a
          number not contemporaneously outstanding.

                    Notwithstanding the foregoing, in case any such
          mutilated, destroyed, lost or stolen Security has become or is
          about to become due and payable, the Company in its discretion
          may, but subject to compliance with the foregoing conditions,
          instead of issuing a new Security, pay such Security.

                    Upon the issuance of any new Security under this
          Section, the Company may require the payment of a sum sufficient
          to cover any tax or other governmental charge that may be imposed
          in relation thereto and any other reasonable expenses (including
          the fees and expenses of the Trustee) connected therewith.

                    Every new Security of any series issued pursuant to
          this Section in lieu of any destroyed, lost or stolen Security
          shall constitute an additional contractual obligation of the
          Company, whether or not the destroyed, lost or stolen Security
          shall be at any time enforceable by anyone other than the Holder
          of such new Security, and any such new Security shall be entitled
          to all the benefits of this Indenture equally and proportionately
          with any and all other Securities of such series duly issued
          hereunder.

                    The provisions of this Section are exclusive and shall
          preclude (to the extent lawful) all other rights and remedies
          with respect to the replacement or payment of mutilated,
          destroyed, lost or stolen Securities.

          SECTION 307.  PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

                    Unless otherwise specified as contemplated by Section
          301 with respect to the Securities of any series, or any Tranche
          thereof, interest on any Security which is payable, and is
          punctually paid or duly provided for, on any Interest Payment
          Date shall be paid to the Person in whose name that Security (or
          one or more Predecessor Securities) is registered at the close of
          business on the Regular Record Date for such interest.

                    Any interest on any Security of any series which is
          payable, but is not punctually paid or duly provided for, on any
          Interest Payment Date, including without limitation interest the
          payment period for which has been extended as specified with
          respect to such series as contemplated by Section 301 (herein
          called "UNPAID INTEREST"), shall forthwith cease to be payable to
          the Holder on the related Regular Record Date by virtue of having
          been such Holder, and such Unpaid Interest may be paid by the
          Company, at its election in each case, as provided in clause (a)
          or (b) below:

                         (a)  The Company may elect to make payment of any
                    Unpaid Interest to the Persons in whose names the
                    Securities of such series (or their respective
                    Predecessor Securities) are registered at the close of
                    business on a date (herein called a "SPECIAL RECORD
                    DATE") for the payment of such Unpaid Interest, which
                    shall be fixed in the following manner.  The Company
                    shall notify the Trustee in writing of the amount of
                    Unpaid Interest proposed to be paid on each Security of
                    such series and the date of the proposed payment, and
                    at the same time the Company shall deposit with the
                    Trustee an amount of money equal to the aggregate
                    amount proposed to be paid in respect of such Unpaid
                    Interest or shall make arrangements satisfactory to the
                    Trustee for such deposit prior to the date of the
                    proposed payment, such money when deposited to be held
                    in trust for the benefit of the Persons entitled to
                    such Unpaid Interest as in this clause provided. 
                    Thereupon the Trustee shall fix a Special Record Date
                    for the payment of such Unpaid Interest which shall be
                    not more than thirty (30) days and not less than ten
                    (10) days prior to the date of the proposed payment and
                    not less than twenty-five (25) days after the receipt
                    by the Trustee of the notice of the proposed payment. 
                    The Trustee shall promptly notify the Company of such
                    Special Record Date and, in the name and at the expense
                    of the Company, shall, not less than fifteen (15) days
                    prior to such Special Record Date, cause notice of the
                    proposed payment of such Unpaid Interest and the
                    Special Record Date therefor to be mailed, first-class
                    postage prepaid, to each Holder of Securities of such
                    series at the address of such Holder as it appears in
                    the Security Register.  Notice of the proposed payment
                    of such Unpaid Interest and the Special Record Date
                    therefor having been so mailed, such Unpaid Interest
                    shall be paid to the Persons in whose names the
                    Securities of such series (or their respective
                    Predecessor Securities) are registered at the close of
                    business on such Special Record Date.

                         (b)  The Company may make payment of any Unpaid
                    Interest on the Securities of any series in any other
                    lawful manner not inconsistent with the requirements of
                    any securities exchange on which such Securities may be
                    listed, and upon such notice as may be required by such
                    exchange, if, after notice given by the Company to the
                    Trustee of the proposed payment pursuant to this
                    clause, such manner of payment shall be deemed
                    practicable by the Trustee.

                    Subject to the foregoing provisions of this Section and
          Section 305, each Security delivered under this Indenture upon
          registration of transfer of or in exchange for or in lieu of any
          other Security shall carry the rights to interest accrued and
          unpaid, and to accrue, which were carried by such other Security.

          SECTION 308.  PERSONS DEEMED OWNERS.

                    Prior to the due presentment of any Security for
          registration of transfer, the Company, the Trustee and any agent
          of the Company or the Trustee may treat the Person in whose name
          any Security is registered as the absolute owner of such Security
          for the purpose of receiving payment of principal of and premium,
          if any, and (subject to Section 307) interest, if any, on such
          Security and for all other purposes whatsoever, whether or not
          such Security be overdue, and neither the Company, the Trustee
          nor any agent of the Company or the Trustee shall be affected by
          notice to the contrary.

          SECTION 309.  CANCELLATION BY SECURITY REGISTRAR.

                    All Securities presented for payment, redemption,
          registration of transfer or exchange shall, if presented to any
          Person other than the Security Registrar, be delivered to the
          Security Registrar and, if not theretofore canceled, shall be
          promptly canceled by the Security Registrar.  The Company may at
          any time deliver to the Security Registrar for cancellation any
          Securities previously authenticated and delivered hereunder which
          the Company may have acquired in any manner whatsoever or which
          the Company shall not have issued and sold, and all Securities so
          delivered shall be promptly canceled by the Security Registrar. 
          Unless by a Company Order the Company shall direct that canceled
          Securities be returned to it, all canceled Securities held by the
          Security Registrar shall be disposed of in accordance with the
          Security Registrar's customary procedures, and the Security
          Registrar shall promptly deliver a certificate of disposition to
          the Trustee and the Company.  The Security Registrar shall
          promptly deliver evidence of any cancellation of a Security in
          accordance with this Section 309 to the Trustee and the Company.

          SECTION 310.  COMPUTATION OF INTEREST.

                    Except as otherwise specified as contemplated by
          Section 301 for Securities of any series, or any Tranche thereof,
          interest on the Securities of each series shall be computed on
          the basis of a three hundred sixty (360) day year consisting of
          twelve (12) thirty (30) day months and, with respect to any
          period less than a full calendar month, on the basis of the
          actual number of days elapsed during such period.

          SECTION 311.  PAYMENT TO BE IN PROPER CURRENCY.

                    In the case of the Securities of any series, or any
          Tranche thereof, denominated in any currency other than Dollars
          or in a composite currency (the "Required Currency"), except as
          otherwise specified with respect to such Securities as
          contemplated by Section 301, the obligation of the Company to
          make any payment of the principal thereof, or the premium, if
          any, or interest, if any, thereon, shall not be discharged or
          satisfied by any tender by the Company, or recovery by the
          Trustee, in any currency other than the Required Currency, except
          to the extent that such tender or recovery shall result in the
          Trustee timely holding the full amount of the Required Currency
          then due and payable.  If any such tender or recovery is in a
          currency other than the Required Currency, the Trustee may take
          such actions as it considers appropriate to exchange such
          currency for the Required Currency.  The costs and risks of any
          such exchange, including without limitation the risks of delay
          and exchange rate fluctuation, shall be borne by the Company, the
          Company shall remain fully liable for any shortfall or
          delinquency in the full amount of Required Currency then due and
          payable, and in no circumstances shall the Trustee be liable
          therefor except in the case of its negligence or willful
          misconduct. 

          SECTION 312.  DELIVERY OF CLASS A BONDS.

                    As contemplated in Section 303 and so long as the
          Collateral Release Date shall not have occurred, prior to the
          authentication and delivery by the Trustee of Securities of any
          series, the Company shall deliver to the Trustee, in addition to
          the documents with respect to the Securities of such series
          specified in Section 303,

                         (a)  Class A Bonds (i) maturing (or being subject
                    to mandatory redemption) on such dates and in such
                    principal amounts that, at each Stated Maturity of the
                    Securities of such series (or the Tranche thereof then
                    to be authenticated and delivered), there shall mature
                    (or be redeemed) Class A Bonds equal in principal
                    amount to the Securities of such series or Tranche then
                    to mature and (ii) containing, in addition to any
                    mandatory redemption provisions applicable to all Class
                    A Bonds Outstanding under the related Class A Mortgage
                    and any mandatory redemption provisions contained
                    therein pursuant to clause (i) above, mandatory
                    redemption provisions correlative to the provisions, if
                    any, for the mandatory redemption (pursuant to a
                    sinking fund or otherwise) of the Securities of such
                    series or Tranche or for the redemption thereof at the
                    option of the Holder; it being expressly understood
                    that such Class A Bonds (x) may, but need not, bear
                    interest, (y) may, but need not, contain provisions for
                    the redemption thereof at the option of the Company,
                    any such redemption to be made at a redemption price or
                    prices not less than the principal amount thereof and
                    (z) shall be held by the Trustee in accordance with
                    this Article.

                         (b)  an Opinion of Counsel to the effect that:

                              (i)  the form or forms of such Class A Bonds
                         have been duly authorized by the Company and have

                         established in conformity with the provisions of
                         the related Class A Mortgage; and

                         delivered by the Trustee in accordance with this
                         Indenture and issued and delivered by the Company
                         in the manner and subject to any conditions
                         specified in such Opinion of Counsel, such Class A
                         Bonds will constitute valid obligations of the
                         Company, entitled to the benefit of the Lien of
                         such Class A Mortgage equally and ratably with all
                         other Class A Bonds then Outstanding under such
                         Class A Mortgage;

                    provided, however, that, with respect to Securities of
                    a series subject to a Periodic Offering, the Trustee
                    shall be entitled to receive such Opinion of Counsel
                    only once at or prior to the time of the first

                    and (iii) above, counsel may opine that:

                         shall have been established in accordance with the
                         instrument or instruments creating the series of

                         been duly authenticated and delivered by the
                         trustee under the related Class A Mortgage or (2)

                         A Bonds will have been duly authenticated and
                         delivered under such Class A Mortgage and (B) when
                         such Class A Bonds shall have been issued and
                         delivered by the Company in the manner and subject
                         to any conditions specified in such Opinion of
                         Counsel, and when the Securities to be

                         entitled to the benefit of the Lien of such Class
                         A Mortgage equally and ratably with all other
                         Class A Bonds then Outstanding under such Class A
                         Mortgage; and

                         (c)  an Expert's Certificate as to the fair value
                    of such Class A Bonds, except as otherwise provided in
                    Section 319(d).

                    Notwithstanding the foregoing, the Trustee shall not be
          entitled to receive Class A Bonds in connection with the
          authentication and delivery of Securities of any series or
          Tranche upon the surrender in exchange therefor of Outstanding
          Securities of another series or Tranche, of like tenor and
          aggregate principal amount, if and to the extent that the Trustee
          shall retain the Class A Bonds delivered to it in connection with
          the authentication and delivery of the Securities being
          surrendered, as contemplated in Section 315.

          SECTION 313.  REGISTRATION AND OWNERSHIP OF CLASS A BONDS.

                    Class A Bonds delivered to the Trustee pursuant to this
          Article shall be registered in the name of the Trustee or its
          nominee and shall be owned and held by the Trustee, subject to
          the provisions of this Indenture, for the benefit of the Holders
          of all Securities from time to time Outstanding, and the Company
          shall have no interest therein.  The Trustee shall be entitled to
          exercise all rights of securityholders under each Class A
          Mortgage either in its discretion or as otherwise provided in
          this Article or in Article Seven.

          SECTION 314.  PAYMENTS ON CLASS A BONDS.

                    (a)  Any payment by the Company of principal of or
          premium or interest on any Class A Bonds delivered to and held by
          the Trustee pursuant to this Article shall be applied by the
          Trustee to the payment of any principal, premium or interest, as
          the case may be, in respect of the Securities which is then due,
          and, to the extent of such application, the obligation of the
          Company hereunder to make such payment in respect of the
          Securities shall be deemed to have been satisfied and discharged.

                    If, at the time of any such payment of principal of
          Class A Bonds delivered to and held by the Trustee pursuant to
          this Article, there shall be no principal then due in respect of
          the Securities, such payment in respect of such Class A Bonds
          shall be held by the Trustee, in trust, and shall be applied to
          the payment of the principal of an equal principal amount of
          Securities at Maturity.

                    If, at the time of any such payment of premium or
          interest on Class A Bonds delivered to and held by the Trustee
          pursuant to this Article, there shall be no premium or interest,
          as the case may be, then due in respect of the Securities, such
          payment in respect of such Class A Bonds shall be remitted to the
          Company upon receipt by the Trustee of a Company Order requesting
          the same, together with an Officer's Certificate stating that no
          Event of Default has occurred and is continuing; provided,
          however, that, if an Event of Default shall have occurred and be
          continuing, such proceeds shall be held by the Trustee, in trust,
          until such Event of Default shall have been cured or waived.

                    (b)  Any payment by the Company hereunder of principal
          of or premium or interest on Securities which shall have been
          authenticated and delivered upon the basis of the delivery to the
          Trustee of Class A Bonds (other than by the application of the
          proceeds of a payment in respect of such Class A Bonds) shall, to
          the extent thereof, be deemed, for all purposes of this
          Indenture, to satisfy and discharge the obligation of the
          Company, if any, to make a payment of principal, premium or
          interest, as the case may be, in respect of such Class A Bonds
          which is then due.

                    (c)  The Trustee hereby waives notice of any redemption
          of Class A Bonds delivered to it pursuant to this Article.

          SECTION 315.  SURRENDER OF CLASS A BONDS.

                    At the time any Securities which shall have been
          authenticated and delivered on the basis of the delivery to the
          Trustee of Class A Bonds cease to be Outstanding (other than as a
          result of the application of the proceeds of the payment or
          redemption of such Class A Bonds), the Trustee shall surrender
          to, or upon the order of, the Company an equal principal amount
          of such Class A Bonds upon receipt by the Trustee of:

                         (a)  a Company Order requesting the surrender of
                    such Class A Bonds; and 

                         (b)  an Expert's Certificate as to the fair value
                    of such Class A Bonds, except as otherwise provided in
                    Section 319(d).

                    Notwithstanding the foregoing, in the event that
          Outstanding Securities of any series or Tranche are surrendered
          in exchange for Securities of another series or Tranche, of like
          tenor and aggregate principal amount, the Trustee shall retain
          the Class A Bonds delivered in connection with the authentication
          and delivery of the Securities being surrendered unless the
          Company, at its election, shall tender new Class A Bonds in
          substitution therefor.

          SECTION 316.  NO TRANSFER OF CLASS A BONDS.

                    Anything in this Indenture to the contrary
          notwithstanding, the Trustee shall not sell, assign or otherwise
          transfer any Class A Bonds delivered to and held by it pursuant
          to this Article except to a successor trustee under this
          Indenture and except as provided in Section 315.  The Company may
          take such actions as it shall deem necessary, desirable or
          appropriate to effect compliance with such restrictions on
          transfer, including the placing of a legend on each such Class A
          Bond and the issuance of stop-transfer instructions to the
          trustee under the related Class A Mortgage or any other transfer
          agent thereunder.

          SECTION 317.  VOTING OF CLASS A BONDS.

                    The Trustee shall, as the holder of Class A Bonds
          delivered to and held by it pursuant to Sections 312 and 313,
          attend such meeting or meetings of bondholders under each Class A
          Mortgage or, at its option, deliver its proxy in connection
          therewith, as relate to matters with respect to which it, as such
          holder, is entitled to vote or consent.  The Trustee, as  such
          holder of Class A Bonds Outstanding under any Class A Mortgage,
          shall be deemed to have voted in favor of, and/or to have
          consented to, such amendments to such Class A Mortgage, if any,
          as shall be set forth in the instrument or instruments
          establishing such Class A Bonds.  As to all other matters arising
          under such Class A Mortgage, so long as no Event of Default
          hereunder shall have occurred and be continuing, either at any
          such meeting or meetings, or otherwise when the consent of the
          holders of the Class A Bonds Outstanding under such Class A
          Mortgage is sought without a meeting, the Trustee shall vote as
          holder of Class A Bonds delivered to and held by it pursuant to
          this Article which were delivered under such Class A Mortgage, or
          shall consent with respect thereto, proportionately with the vote
          or consent of the holders of all other Class A Bonds Outstanding
          under such Class A Mortgage the holders of which are eligible to
          vote or consent, as indicated in a Class A Bondholder's
          Certificate delivered to the Trustee; provided, however, that the
          Trustee shall not so vote in favor of, or so consent to, any
          amendment or modification of a Class A Mortgage which, if it were
          an amendment or modification of this Indenture, would require the
          consent of Holders, without the prior consent, obtained in the
          manner prescribed in Section 1102, of Holders of Securities which
          would be required under said Section 1102 for such an amendment
          or modification of this Indenture.

                    For purposes of this Section, "CLASS A BONDHOLDER'S
          CERTIFICATE" means a certificate signed by the temporary
          chairman, the temporary secretary, the permanent chairman, the
          permanent secretary, or an inspector of votes at any meeting or
          meetings of bondholders under a Class A Mortgage, or by the
          trustee under such Class A Mortgage in the case of consents of
          such bondholders which are sought without a meeting, which states
          what the signer thereof reasonably believes will be the
          proportionate votes or consents of the holders of all Class A
          Bonds (other than the Class A Bonds delivered to and held by the
          Trustee pursuant to this Article) outstanding under such Class A
          Mortgage and counted for the purposes of determining whether such
          bondholders have approved or consented to the matter put before
          them.

          SECTION 318.  DISCHARGE OF CLASS A MORTGAGES.

                    The Trustee shall surrender for cancellation to the
          trustee under any Class A Mortgage all Class A Bonds delivered to
          and then held by it pursuant to this Article which were delivered
          under such Class A Mortgage upon receipt by the Trustee of:

                         (a)  a Company Order requesting such surrender for
                    cancellation of such Class A Bonds;

                         (b)  an Officer's Certificate to the effect that
                    no Class A Bonds are Outstanding under such Class A
                    Mortgage other than Class A Bonds delivered to and held
                    by the Trustee pursuant to this Article and that
                    promptly upon such surrender such Class A Mortgage will
                    be satisfied and discharged pursuant to the terms
                    thereof;

                         (c)  an Expert's Certificate as to the fair value
                    of such Class A Bonds to be so surrendered, except as
                    otherwise provided in Section 319(d); and

                         (d)  if, at the time of such surrender, any Class
                    A Bonds shall be Outstanding under another Class A
                    Mortgage, 

                              (i)  Class A Bonds authenticated and
                         delivered under such other Class A Mortgage in the
                         same aggregate principal amount or amounts,
                         bearing interest at the same rate or rates and
                         having the same Stated Maturity or Maturities as
                         the Class A Bonds to be surrendered; 

                              (ii) an Expert's Certificate as to the fair
                         value of such Class A Bonds so delivered, except
                         as otherwise provided in Section 319(d); and 

                              (iii)     an Opinion of Counsel

                                   (A) to the effect that, upon
                              satisfaction and discharge of the Class A
                              Mortgage under which the Class A Bonds to be
                              so surrendered were authenticated and
                              delivered, the Lien of such other Class A
                              Mortgage on the property formerly subject to
                              the Lien of such Class A Mortgage to be
                              satisfied and discharged will be subject to
                              no Lien except the Lien of such other Class A
                              Mortgage and other Liens of the character
                              permitted to exist or to be thereafter
                              created under such Class A Mortgage to be
                              satisfied and discharged; and

                                   (B)  to the effect set forth in clause
                              (b) of Section 312 with respect to such Class
                              A Bonds so authenticated and delivered under
                              such other Class A Mortgage and delivered to
                              the Trustee; or

                         (e)  if, at the time of such surrender, there is
                    no other Class A Mortgage in effect,

                              (i)  an Officer's Certificate to the effect
                         that upon such satisfaction and discharge, the
                         Company will be in compliance with the covenant
                         contained in Section 508; and

                              (ii) an Opinion of Counsel to the effect
                         that, upon satisfaction and discharge of such
                         Class A Mortgage, the property formerly subject to
                         the Lien of such Class A Mortgage will be subject
                         to no Lien which secures Secured Debt other than
                         Permitted Secured Debt.

          SECTION 319.  EXPERTS' CERTIFICATES.

                    (a)  Each Expert's Certificate as to the fair value to
          the Company of Class A Bonds delivered to the Trustee pursuant to
          Section 312 or 318, or as to the fair value of Class A Bonds to
          be surrendered pursuant to Section 315 or 318, shall be made by
          an Independent Expert if the fair value to the Company of such
          Class A Bonds so delivered and of all other Class A Bonds so
          delivered, or the fair value of the Class A Bonds to be so
          surrendered and of all other Class A Bonds so surrendered, as the
          case may be, since the commencement of the then current calendar
          year, as set forth in the certificates required by this
          Indenture, is ten percentum (10%) or more of the aggregate
          principal amount of the Securities at the time Outstanding; but
          such Expert's Certificate shall not be required to be made by an
          Independent Expert in the case of any delivery or surrender of
          Class A Bonds if the fair value to the Company thereof or the
          fair value thereof, as the case may be, and as set forth in the
          certificates required by this Indenture, is less than Twenty-five
          Thousand Dollars ($25,000) or less than one percentum (1%) of the
          aggregate principal amount of the Securities at the time
          Outstanding.

                    (b)  Each Expert's Certificate with respect to the fair
          value of Class A Bonds being surrendered shall state that, in the
          opinion of the signer, such surrender will not impair the
          security under this Indenture in contravention of the provisions
          hereof; it being understood, however, that no surrender of Class
          A Bonds effected in accordance with the provisions, and in
          compliance with the conditions, set forth in this Article and in
          Sections 102 and 103 shall be deemed to impair the security of
          this Indenture in contravention of any provision hereof.

                    (c)  In assessing the fair value to the Company or the
          fair value, as the case may be, of any Class A Bond, an Expert
          may consider, among other things, (i) the principal amount and
          remaining term to Stated Maturity of, the interest rate, if any,
          on and the redemption provisions contained in such Class A Bond,
          (ii) the creditworthiness of the Company, including the effect,
          if any, of the prospective delivery or surrender of such Class A
          Bonds on the ratings assigned to the Securities by nationally
          recognized statistical rating organizations, (iii) prevailing
          economic and market conditions, (iv) the restrictions on the
          transfer of such Class A Bond contained in Section 316, (v)
          whether or not, at the time of such assessment, the obligations
          of the Company in respect of such Class A Bond shall, under the
          provisions of the related Class A Mortgage or under the
          provisions of this Indenture, or both, be deemed to have been
          satisfied and discharged, (vi) the effect, if any, of the
          prospective delivery or surrender of such Class A Bond on the
          nature and extent of the security and/or protection available to
          the Holders under this Indenture and (vii) any other relevant
          factors.

                    (d)  Anything in this Indenture to the contrary
          notwithstanding, the Company shall not be required to deliver any
          Expert's Certificate pursuant to Section 312, 315 or 318 if, in
          any particular case, the Company shall have delivered to the
          Trustee an Opinion of Counsel to the effect that the Expert's
          Certificate otherwise required to be delivered shall not, in such
          case, be required by the Trust Indenture Act.


                                     ARTICLE FOUR

                               REDEMPTION OF SECURITIES

          SECTION 401.  APPLICABILITY OF ARTICLE.

                    Securities of any series, or any Tranche thereof, which
          are redeemable before their Stated Maturity shall be redeemable
          in accordance with their terms and (except as otherwise specified
          as contemplated by Section 301 for Securities of such series or
          Tranche) in accordance with this Article.

          SECTION 402.  ELECTION TO REDEEM; NOTICE TO TRUSTEE.

                    The election of the Company to redeem any Securities
          shall be evidenced by a Board Resolution or an Officer's
          Certificate.  The Company shall, at least forty-five (45) days
          prior to the Redemption Date fixed by the Company (unless a
          shorter notice shall be satisfactory to the Trustee), notify the
          Trustee in writing of such Redemption Date and of the principal
          amount of such Securities to be redeemed.  In the case of any
          redemption of Securities (a) prior to the expiration of any
          restriction on such redemption provided in the terms of such
          Securities or elsewhere in this Indenture or (b) pursuant to an
          election of the Company which is subject to a condition specified
          in the terms of such Securities, the Company shall furnish the
          Trustee with an Officer's Certificate evidencing compliance with
          such restriction or condition.

          SECTION 403.  SELECTION OF SECURITIES TO BE REDEEMED.

                    If less than all the Securities of any series, or any
          Tranche thereof, are to be redeemed, the particular Securities to
          be redeemed shall be selected by the Security Registrar from the
          Outstanding Securities of such series or Tranche not previously
          called for redemption, by such method as shall be provided for
          any particular series or Tranche, or, in the absence of any such
          provision, by such method of random selection as the Security
          Registrar shall deem fair and appropriate and which may, in any
          case, provide for the selection for redemption of portions (in
          any authorized denomination for Securities of such series or
          Tranche) of the principal amount of Securities of such series or
          Tranche having a denomination larger than the minimum authorized
          denomination for Securities of such series or Tranche; provided,
          however, that if, as indicated in an Officer's Certificate, the
          Company shall have offered to purchase all or any principal
          amount of the Securities then Outstanding of any series, or any
          Tranche thereof, and less than all of such Securities as to which
          such offer was made shall have been tendered to the Company for
          such purchase, the Security Registrar, if so directed by Company
          Order, shall select for redemption all or any principal amount of
          such Securities which have not been so tendered.

                    The Security Registrar shall promptly notify the
          Company and the Trustee in writing of the Securities selected for
          redemption and, in the case of any Securities selected to be
          redeemed in part, the principal amount thereof to be redeemed.

                    For all purposes of this Indenture, unless the context
          otherwise requires, all provisions relating to the redemption of
          Securities shall relate, in the case of any Securities redeemed
          or to be redeemed only in part, to the portion of the principal
          amount of such Securities which has been or is to be redeemed.

          SECTION 404.  NOTICE OF REDEMPTION.

                    Notice of redemption shall be given in the manner
          provided in Section 106 to the Holders of the Securities to be
          redeemed not less than thirty (30) nor more than sixty (60) days
          prior to the Redemption Date.

                    All notices of redemption shall state:

                         (a)  the Redemption Date,

                         (b)  the Redemption Price,

                         (c)  if less than all the Securities of any series
                    or Tranche are to be redeemed, the identification of
                    the particular Securities to be redeemed and the
                    portion of the principal amount of any Security to be
                    redeemed in part,

                         (d)  that on the Redemption Date the Redemption
                    Price, together with accrued interest, if any, to the
                    Redemption Date, will become due and payable upon each
                    such Security to be redeemed and, if applicable, that
                    interest thereon will cease to accrue on and after said
                    date,

                         (e)  the place or places where such Securities are
                    to be surrendered for payment of the Redemption Price
                    and accrued interest, if any, unless it shall have been
                    specified as contemplated by Section 301 with respect
                    to such Securities that such surrender shall not be
                    required,

                         (f)  that the redemption is for a sinking or other
                    fund, if such is the case, and

                         (g)  such other matters as the Company shall deem
                    desirable or appropriate.

                    With respect to any notice of redemption of Securities
          at the election of the Company, unless, upon the giving of such
          notice, such Securities shall be deemed to have been paid in
          accordance with Section 601, such notice may state that such
          redemption shall be conditional upon the receipt by the Paying
          Agent or Agents for such Securities, on or prior to the date
          fixed for such redemption, of money sufficient to pay the
          principal of and premium, if any, and interest, if any, on such
          Securities and that if such money shall not have been so received
          such notice shall be of no force or effect and the Company shall
          not be required to redeem such Securities.  In the event that
          such notice of redemption contains such a condition and such
          money is not so received, the redemption shall not be made and
          within a reasonable time thereafter notice shall be given, in the
          manner in which the notice of redemption was given, that such
          money was not so received and such redemption was not required to
          be made, and the Paying Agent or Agents for the Securities
          otherwise to have been redeemed shall promptly return to the
          Holders thereof any of such Securities which had been surrendered
          for payment upon such redemption.

                    Notice of redemption of Securities to be redeemed at
          the election of the Company, and any notice of non-satisfaction
          of a condition for redemption as aforesaid, shall be given by the
          Company or, upon Company Request, by the Security Registrar in
          the name and at the expense of the Company.  Notice of mandatory
          redemption of Securities shall be given by the Security Registrar
          in the name and at the expense of the Company.

          SECTION 405.  SECURITIES PAYABLE ON REDEMPTION DATE.

                    Notice of redemption having been given as aforesaid,
          and the conditions, if any, set forth in such notice having been
          satisfied, the Securities or portions thereof so to be redeemed
          shall, on the Redemption Date, become due and payable at the
          Redemption Price therein specified, and from and after such date
          (unless, in the case of an unconditional notice of redemption,
          the Company shall default in the payment of the Redemption Price
          and accrued interest, if any) such Securities or portions
          thereof, if interest-bearing, shall cease to bear interest.  Upon
          surrender of any such Security for redemption in accordance with
          such notice, such Security or portion thereof shall be paid by
          the Company at the Redemption Price, together with accrued
          interest, if any, to the Redemption Date; provided, however, that
          no such surrender shall be a condition to such payment if so
          specified as contemplated by Section 301 with respect to such
          Security; and provided, further, that, except as otherwise
          specified as contemplated by Section 301 with respect to such
          Security, any installment of interest on any Security the Stated
          Maturity of which installment is on or prior to the Redemption
          Date shall be payable to the Holder of such Security, or one or
          more Predecessor Securities, registered as such at the close of
          business on the related Regular Record Date according to the
          terms of such Security and subject to the provisions of Section
          307.

          SECTION 406.  SECURITIES REDEEMED IN PART.

                    Upon the surrender of any Security which is to be
          redeemed only in part at a Place of Payment therefor (with, if
          the Company or the Trustee so requires, due endorsement by, or a
          written instrument of transfer in form satisfactory to the
          Company or the Trustee, as the case may be, duly executed by, the
          Holder thereof or his attorney duly authorized in writing), the
          Company shall execute, and the Trustee shall authenticate and
          deliver to the Holder of such Security, without service charge, a
          new Security or Securities of the same series and Tranche, of any
          authorized denomination requested by such Holder and of like
          tenor and in aggregate principal amount equal to and in exchange
          for the unredeemed portion of the principal of the Security so
          surrendered.


                                     ARTICLE FIVE

                                      COVENANTS

          SECTION 501.  PAYMENT OF SECURITIES.

                    The Company shall pay the principal of and premium, if
          any, and interest, if any, on the Securities of each series in
          accordance with the terms of such Securities and this Indenture.

          SECTION 502.  MAINTENANCE OF OFFICE OR AGENCY.

                    The Company shall maintain in each Place of Payment for
          the Securities of each series, or any Tranche thereof, an office
          or agency where payment of such Securities shall be made, where
          the registration of transfer or exchange of such Securities may
          be effected and where notices and demands to or upon the Company
          in respect of such Securities and this Indenture may be served. 
          The Company shall give prompt written notice to the Trustee of
          the location, and any change in the location, of each such office
          or agency and prompt notice to the Holders of any such change in
          the manner specified in Section 106.  If at any time the Company
          shall fail to maintain any such required office or agency in
          respect of Securities of any series, or any Tranche thereof, or
          shall fail to furnish the Trustee with the address thereof,
          payment of such Securities shall be made, registration of
          transfer or exchange thereof may be effected and notices and
          demands in respect thereof may be served at the Corporate Trust
          Office of the Trustee, and the Company hereby appoints the
          Trustee as its agent for all such purposes in any such event.

                    The Company may also from time to time designate one or
          more other offices or agencies with respect to the Securities of
          one or more series, or any Tranche thereof, for any or all of the
          foregoing purposes and may from time to time rescind such
          designations; provided, however, that, unless otherwise specified
          as contemplated by Section 301 with respect to the Securities of
          such series or Tranche, no such designation or rescission shall
          in any manner relieve the Company of its obligation to maintain
          an office or agency for such purposes in each Place of Payment
          for such Securities in accordance with the requirements set forth
          above.  The Company shall give prompt written notice to the
          Trustee, and prompt notice to the Holders in the manner specified
          in Section 106, of any such designation or rescission and of any
          change in the location of any such other office or agency.

                    Anything herein to the contrary notwithstanding, any
          office or agency required by this Section may be maintained at an
          office of the Company, in which event the Company shall perform
          all functions to be performed at such office or agency.

          SECTION 503.  MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST.

                    If the Company shall at any time act as its own Paying
          Agent with respect to the Securities of any series, or any
          Tranche thereof, it shall, on or before each due date of the
          principal of and premium, if any, and interest, if any, on any of
          such Securities, segregate and hold in trust for the benefit of
          the Persons entitled thereto a sum sufficient to pay the
          principal and premium or interest so becoming due until such sums
          shall be paid to such Persons or otherwise disposed of as herein
          provided.  The Company shall promptly notify the Trustee of any
          failure by the Company (or any other obligor on such Securities)
          to make any payment of principal of or premium, if any, or
          interest, if any, on such Securities.

                    Whenever the Company shall have one or more Paying
          Agents for the Securities of any series, or any Tranche thereof,
          it shall, on or before each due date of the principal of and
          premium, if any, and interest, if any, on such Securities,
          deposit with such Paying Agents sums sufficient (without
          duplication) to pay the principal and premium or interest so
          becoming due, such sums to be held in trust for the benefit of
          the Persons entitled to such principal, premium or interest, and
          (unless such Paying Agent is the Trustee) the Company shall
          promptly notify the Trustee of any failure by it so to act.

                    The Company shall cause each Paying Agent for the
          Securities of any series, or any Tranche thereof, other than the
          Company or the Trustee, to execute and deliver to the Trustee an
          instrument in which such Paying Agent shall agree with the
          Trustee, subject to the provisions of this Section, that such
          Paying Agent shall:

                         (a)  hold all sums held by it for the payment of
                    the principal of and premium, if any, or interest, if
                    any, on such Securities in trust for the benefit of the
                    Persons entitled thereto until such sums shall be paid
                    to such Persons or otherwise disposed of as herein
                    provided;

                         (b)  give the Trustee notice of any failure by the
                    Company (or any other obligor upon such Securities) to
                    make any payment of principal of or premium, if any, or
                    interest, if any, on such Securities; and 

                         (c)  at any time during the continuance of any
                    such failure, upon the written request of the Trustee,
                    forthwith pay to the Trustee all sums so held in trust
                    by such Paying Agent and furnish to the Trustee such
                    information as it possesses regarding the names and
                    addresses of the Persons entitled to such sums.

                    The Company may at any time pay, or by Company Order
          direct any Paying Agent to pay, to the Trustee all sums held in
          trust by the Company or such Paying Agent, such sums to be held
          by the Trustee upon the same trusts as those upon which such sums
          were held by the Company or such Paying Agent and, if so stated
          in a Company Order delivered to the Trustee, in accordance with
          the provisions of Article Six; and, upon such payment by any
          Paying Agent to the Trustee, such Paying Agent shall be released
          from all further liability with respect to such money.

                    Any money deposited with the Trustee or any Paying
          Agent, or then held by the Company, in trust for the payment of
          the principal of and premium, if any, or interest, if any, on any
          Security and remaining unclaimed for two years after such
          principal and premium, if any, or interest, if any, has become
          due and payable shall be paid to the Company on Company Request,
          or, if then held by the Company, shall be discharged from such
          trust; and, upon such payment or discharge, the Holder of such
          Security shall, as an unsecured general creditor and not as the
          Holder of an Outstanding Security, look only to the Company for
          payment of the amount so due and payable and remaining unpaid,
          and all liability of the Trustee or such Paying Agent with
          respect to such trust money, and all liability of the Company as
          trustee thereof, shall thereupon cease; provided, however, that
          the Trustee or such Paying Agent, before being required to make
          any such payment to the Company, may at the expense of the
          Company cause to be mailed, on one occasion only, notice to such
          Holder that such money remains unclaimed and that, after a date
          specified therein, which shall not be less than thirty (30) days
          from the date of such mailing, any unclaimed balance of such
          money then remaining will be paid to the Company.

          SECTION 504.  CORPORATE EXISTENCE.

                    Subject to the rights of the Company under Article Ten,
          the Company shall do or cause to be done all things necessary to
          preserve and keep its corporate existence in full force and
          effect.

          SECTION 505.  MAINTENANCE OF PROPERTIES.

                    The Company shall cause (or, with respect to property
          owned in common with others, make reasonable effort to cause) all
          its properties used or useful in the conduct of its businesses,
          considered as a whole, to be maintained and kept in good
          condition, repair and working order and shall cause (or, with
          respect to property owned in common with others, make reasonable
          effort to cause) to be made such repairs, renewals, replacements,
          betterments and improvements thereof, as, in the judgment of the
          Company, may be necessary in order that the operation of such
          properties, considered as a whole, may be conducted in accordance
          with common industry practice; provided, however, that nothing in
          this Section shall prevent the Company from discontinuing, or
          causing the discontinuance of, the operation and maintenance of
          any of its properties; and provided, further, that nothing in
          this Section shall prevent the Company from selling, transferring
          or otherwise disposing of, or causing the sale, transfer or other
          disposition of, any of its properties.

          SECTION 506.  WAIVER OF CERTAIN COVENANTS.

                    The Company may omit in any particular instance to
          comply with any term, provision or condition set forth in

                         (a)  any covenant or restriction specified with
                    respect to the Securities of any one or more series, or
                    any Tranche or Tranches thereof, as contemplated by
                    Section 301 if before the time for such compliance the
                    Holders of a majority in aggregate principal amount of
                    the Outstanding Securities of all series and Tranches
                    with respect to which compliance with such covenant or
                    restriction is to be omitted, considered as one class,
                    shall, by Act of such Holders, either waive such
                    compliance in such instance or generally waive
                    compliance with such term, provision or condition;
                    provided, however, that no such waiver shall be
                    effective as to any matters contemplated in clause (a),
                    (b) or (c) in Section 1102 without consent of the
                    Holders specified in such Section; and

                         (b)  Section 504 or 505 or Article Ten if before
                    the time for such compliance the Holders of a majority
                    in principal amount of Securities Outstanding under
                    this Indenture shall, by Act of such Holders, either
                    waive such compliance in such instance or generally
                    waive compliance with such term, provision or
                    condition;

          but, in either case, no such waiver shall extend to or affect
          such term, provision or condition except to the extent so
          expressly waived, and, until such waiver shall become effective,
          the obligations of the Company and the duties of the Trustee in
          respect of any such term, provision or condition shall remain in
          full force and effect.

          SECTION 507.  ANNUAL OFFICER'S CERTIFICATE AS TO COMPLIANCE. 

                    Not later than December 1 in each year, commencing
          December 1, 1998, the Company shall deliver to the Trustee an
          Officer's Certificate which need not comply with Section 102,
          executed by the principal executive officer, the principal
          financial officer or the principal accounting officer of the
          Company, as to such officer's knowledge of the Company's
          compliance with all conditions and covenants under this
          Indenture, such compliance to be determined without regard to any
          period of grace or requirement of notice under this Indenture.

          SECTION 508.  LIMITATION ON SECURED DEBT.

                    (a)  On and after the Collateral Release Date and so
          long as any Securities shall remain Outstanding, the Company
          shall not create, issue, incur or assume any Secured Debt other
          than Permitted Secured Debt without the consent of the Holders of
          a majority in principal amount of the Outstanding Securities of
          all series and Tranches, considered as one class.

                    (b)  the provisions of clause (a) above shall not
          prohibit the creation, issuance, incurrence or assumption of any
          Secured Debt if either

                         (i)  the Company shall make effective provision
                    whereby all Securities then Outstanding shall be
                    secured equally and ratably with such Secured Debt; or

                         (ii) the Company shall deliver to the Trustee
                    bonds, notes or other evidences of indebtedness secured
                    by the Lien which secures such Secured Debt
                    (hereinafter called "Secured Obligations") (A) in an
                    aggregate principal amount equal to the aggregate
                    principal amount of the  Securities then Outstanding,
                    (B) maturing (or being subject to mandatory redemption)
                    on such dates and in such principal amounts that, at
                    each Stated Maturity of the Outstanding  Securities,
                    there shall mature (or be redeemed) Secured Obligations
                    equal in principal amount to the Securities then to
                    mature and (C) containing, in addition to any mandatory

                    has occurred and is continuing and (2) no event has
                    occurred and is continuing which entitles the secured
                    party under such Lien to accelerate the maturity of the
                    indebtedness outstanding thereunder and (B) stating the

          requisite to the validity of such redemption shall have been
          given or irrevocable authority shall have been given by the
          Company to the Trustee to give such notice, under arrangements
          satisfactory to the Trustee; and provided, further, that the
          Company shall have delivered to the Trustee and such Paying
          Agent:

                         (x)  if such deposit shall have been made prior to
                    the Maturity of such Securities, a Company Order
                    stating that the money and Eligible Obligations
                    deposited in accordance with this Section shall be held
                    in trust, as provided in Section 603; 

                         (y)  if Eligible Obligations shall have been
                    deposited, an Opinion of Counsel to the effect that
                    such obligations constitute Eligible Obligations and do
                    not contain provisions permitting the redemption or
                    other prepayment thereof at the option of the issuer
                    thereof, and an opinion of an independent public
                    accountant of nationally recognized standing, selected
                    by the Company, to the effect that the other
                    requirements set forth in clause (b) and, if
                    applicable, (c) above have been satisfied; and 

                         (z)  if such deposit shall have been made prior to
                    the Maturity of such Securities, an Officer's
                    Certificate stating the Company's intention that, upon
                    delivery of such Officer's Certificate, its
                    indebtedness in respect of such Securities or portions
                    thereof will have been satisfied and discharged as
                    contemplated in this Section.

                    Upon the deposit of money or Eligible Obligations, or
          both, in accordance with this Section, together with the
          documents required by clauses (x), (y) and (z) above, the Trustee
          shall, upon Company Request, acknowledge in writing that such
          Securities or portions thereof are deemed to have been paid for
          all purposes of this Indenture and that the entire indebtedness
          of the Company in respect thereof has been satisfied and
          discharged as contemplated in this Section.  In the event that
          all of the conditions set forth in the preceding paragraph shall
          have been satisfied in respect of any Securities or portions
          thereof except that, for any reason, the Officer's Certificate
          specified in clause (z) (if otherwise required) shall not have
          been delivered, such Securities or portions thereof shall
          nevertheless be deemed to have been paid for all purposes of this
          Indenture, and the Holders of such Securities or portions thereof
          shall nevertheless be no longer entitled to the benefits provided
          by this Indenture or of any of the covenants of the Company under
          Article Five (except the covenants contained in Sections 502 and
          503) or any other covenants made in respect of such Securities or
          portions thereof as contemplated by Section 301, but the
          indebtedness of the Company in respect of such Securities or
          portions thereof shall not be deemed to have been satisfied and
          discharged prior to Maturity for any other purpose; and, upon
          Company Request, the Trustee shall acknowledge in writing that
          such Securities or portions thereof are deemed to have been paid
          for all purposes of this Indenture.

                    If payment at Stated Maturity of less than all of the
          Securities of any series, or any Tranche thereof, is to be
          provided for in the manner and with the effect provided in this
          Section, the Security Registrar shall select such Securities, or
          portions of principal amount thereof, in the manner specified by
          Section 403 for selection for redemption of less than all the
          Securities of a series or Tranche.

                    In the event that Securities which shall be deemed to
          have been paid for purposes of this Indenture, and, if such is
          the case, in respect of which the Company's indebtedness shall
          have been satisfied and discharged, all as provided in this
          Section, do not mature and are not to be redeemed within the
          sixty (60) day period commencing with the date of the deposit of
          moneys or Eligible Obligations, as aforesaid, the Company shall,
          as promptly as practicable, give a notice, in the same manner as
          a notice of redemption with respect to such Securities, to the
          Holders of such Securities to the effect that such deposit has
          been made and the effect thereof.

                    Notwithstanding that any Securities shall be deemed to
          have been paid for purposes of this Indenture, as aforesaid, the
          obligations of the Company and the Trustee in respect of such
          Securities under Sections 304, 305, 306, 404, 502, 503, 807 and
          814 and this Article shall survive.

                    The Company shall pay, and shall indemnify the Trustee
          or any Paying Agent with which Eligible Obligations shall have
          been deposited as provided in this Section against, any tax, fee
          or other charge imposed on or assessed against such Eligible
          Obligations or the principal or interest received in respect of
          such Eligible Obligations, including, but not limited to, any
          such tax payable by any entity deemed, for tax purposes, to have
          been created as a result of such deposit.

                    Anything herein to the contrary notwithstanding, (a)
          if, at any time after a Security would be deemed to have been
          paid for purposes of this Indenture, and, if such is the case,
          the Company's indebtedness in respect thereof would be deemed to
          have been satisfied and discharged, pursuant to this Section
          (without regard to the provisions of this paragraph), the Trustee
          or any Paying Agent, as the case may be, (i) shall be required to
          return the money or Eligible Obligations, or combination thereof,
          deposited with it as aforesaid to the Company or its
          representative under any applicable Federal or State bankruptcy,
          insolvency or other similar law or (ii) are unable to apply any
          money held by the Trustee as provided in this Section and Section
          603 with respect to such Security by reason of any order or
          judgment of any court or governmental authority enjoining,
          restraining or otherwise prohibiting such application, such
          Security shall thereupon be deemed retroactively not to have been
          paid and any satisfaction and discharge of the Company's
          indebtedness in respect thereof shall retroactively be deemed not
          to have been effected, and such Security shall be deemed to
          remain Outstanding and (b) any satisfaction and discharge of the
          Company's indebtedness in respect of any Security shall be
          subject to the provisions of the last paragraph of Section 503.

          SECTION 602.  SATISFACTION AND DISCHARGE OF INDENTURE.

                    This Indenture shall upon Company Request cease to be
          of further effect (except as hereinafter expressly provided), and
          the Trustee, at the expense of the Company, shall execute such
          instruments as the Company shall reasonably request to evidence
          and acknowledge the satisfaction and discharge of this Indenture,
          when:

                         (a)  no Securities remain Outstanding hereunder;
                    and 

                         (b)  the Company has paid or caused to be paid all
                    other sums payable hereunder by the Company; 

          provided, however, that if, in accordance with the last paragraph
          of Section 601, any Security, previously deemed to have been paid
          for purposes of this Indenture, shall be deemed retroactively not
          to have been so paid, this Indenture shall thereupon be deemed
          retroactively not to have been satisfied and discharged, as
          aforesaid, and to remain in full force and effect, and the
          Company shall execute and deliver such instruments as the Trustee
          shall reasonably request to evidence and acknowledge the same.

                    Notwithstanding the satisfaction and discharge of this
          Indenture as aforesaid, the obligations of the Company and the
          Trustee under Sections 304, 305, 306, 404, 502, 503, 807 and 814
          and this Article shall survive.

                    Upon satisfaction and discharge of this Indenture as
          provided in this Section, the Trustee shall turn over to the
          Company any and all money, securities and other property then
          held by the Trustee for the benefit of the Holders of the
          Securities (other than money and Eligible Obligations held by the
          Trustee pursuant to Section 603) and shall execute and deliver to
          the Company such instruments as, in the judgment of the Company,
          shall be necessary, desirable or appropriate to effect or
          evidence the satisfaction and discharge of this Indenture.

          SECTION 603.  APPLICATION OF TRUST MONEY.

                    Neither the Eligible Obligations nor the money
          deposited pursuant to Section 601, nor the principal or interest
          payments on any such Eligible Obligations, shall be withdrawn or
          used for any purpose other than, and shall be held in trust for,
          the payment of the principal of and premium, if any, and
          interest, if any, on the Securities or portions of principal
          amount thereof in respect of which such deposit was made, all
          subject, however, to the provisions of Section 503; provided,
          however, that any cash received from such principal or interest
          payments on such Eligible Obligations, if not then needed for
          such purpose, shall, to the extent practicable and upon Company
          Request and delivery to the Trustee of the documents referred to
          in clause (y) in the first paragraph of Section 601, be invested
          in Eligible Obligations of the type described in clause (b) in
          the first paragraph of Section 601 maturing at such times and in
          such amounts as shall be sufficient, together with any other
          moneys and the proceeds of any other Eligible Obligations then
          held by the Trustee, to pay when due the principal of and
          premium, if any, and interest, if any, due and to become due on
          such Securities or portions thereof on and prior to the Maturity
          thereof, and interest earned from such reinvestment shall be paid
          over to the Company as received, free and clear of any trust,
          lien or pledge under this Indenture; and provided, further, that
          any moneys held in accordance with this Section on the Maturity
          of all such Securities in excess of the amount required to pay
          the principal of and premium, if any, and interest, if any, then
          due on such Securities shall be paid over to the Company free and
          clear of any trust, lien or pledge under this Indenture; and
          provided, further, that if an Event of Default shall have
          occurred and be continuing, moneys to be paid over to the Company
          pursuant to this Section shall be held until such Event of
          Default shall have been waived or cured.

                             EVENTS OF DEFAULT; REMEDIES

          SECTION 701.  EVENTS OF DEFAULT.

                    "EVENT OF DEFAULT", wherever used herein with respect
          to the Securities, means any of the following events which shall
          have occurred and be continuing:

                    (a)  failure to pay interest, if any, on any Security,
               within sixty (60) days after the same becomes due and
               payable if such failure shall occur prior to the Collateral
               Release Date, or within thirty (30) days after the same
               becomes due and payable if such failure shall occur on or
               after the Collateral Release Date; provided, however, that
               no such failure shall constitute an "Event of Default" if
               the Company shall have made a valid extension of the
               interest payment period with respect to the Securities of
               the series, of which such Security is a part, if so provided
               with respect to such series as contemplated by Section 301;
               or

                    (b)  failure to pay the principal of or premium, if
               any, on any Security when due; provided, however, that no
               such failure shall constitute an "Event of Default" if the
               Company shall have made a valid extension of the Maturity of
               the Securities of the series, of which such Security is a
               part, if so provided with respect to such series as
               contemplated by Section 301; or

                    (c)  failure to perform or breach of any covenant or
               warranty of the Company in this Indenture (other than a
               covenant or warranty, a default in the performance of which
               or breach of which is elsewhere in this Section specifically
               dealt with) for a period of ninety (90) days after there has
               been given, by registered or certified mail, to the Company
               by the Trustee, or to the Company and the Trustee by the
               Holders of at least twenty-five percentum (25%) in principal
               amount of the Securities then Outstanding, a written notice
               specifying such default or breach and requiring it to be
               remedied and stating that such notice is a "NOTICE OF
               DEFAULT" hereunder, unless the Trustee, or the Trustee and
               the Holders of a principal amount of Securities not less
               than the principal amount of Securities the Holders of which
               gave such notice, as the case may be, shall agree in writing
               to an extension of such period prior to its expiration;
               provided, however, that the Trustee, or the Trustee and the
               Holders of such principal amount of Securities, as the case
               may be, shall be deemed to have agreed to an extension of
               such period if corrective action is initiated by the Company
               within such period and is being diligently pursued; or

                    (d)  a default under any bond, debenture, note or other
               evidence of Debt of the Company or under any mortgage,
               indenture or other instrument under which there may be
               issued or by which there may be secured or evidenced any
               Debt of the Company (including this Indenture), whether such
               Debt now exists or shall hereafter be created, which default
               (1) shall constitute a failure to make any payment in excess
               of $5,000,000 of the principal of or interest on such Debt
               when due and payable after the expiration of any applicable
               grace period with respect thereto or (2) shall have resulted
               in such Debt in an amount in excess of $10,000,000 becoming
               or being declared due and payable prior to the date on which
               it would otherwise have become due and payable, without such
               payment having been made, such Debt having been discharged,
               or such acceleration having been rescinded or annulled, as
               the case may be, within a period of ninety (90) days after
               there shall have been given, by registered or certified
               mail, to the Company by the Trustee or to the Company and
               the Trustee by the Holders of at least twenty-five percentum
               (25%) in principal amount of the Securities then Outstanding
               a written notice specifying such default and requiring the
               Company to cause such payment to be made, such Debt to be
               discharged or such acceleration to be rescinded or annulled,
               as the case may be, and stating that such notice is a Notice
               of Default hereunder; it being understood, however, that no
               event described in this clause (d) shall constitute an Event
               of Default prior to the Collateral Release Date; or

                    (e)  the entry by a court having jurisdiction in the
               premises of (i) a decree or order for relief in respect of
               the Company in an involuntary case or proceeding under any
               applicable Federal or State bankruptcy, insolvency,
               reorganization or other similar law or (ii) a decree or
               order adjudging the Company a bankrupt or insolvent, or
               approving as properly filed a petition by one or more
               Persons other than the Company seeking reorganization,
               arrangement, adjustment or composition of or in respect of
               the Company under any applicable Federal or State law, or
               appointing a custodian, receiver, liquidator, assignee,
               trustee, sequestrator or other similar official for the
               Company or for any substantial part of its property, or
               ordering the winding-up or liquidation of its affairs, and
               any such decree or order for relief or any such other decree
               or order shall have remained unstayed and in effect for a
               period of ninety (90) consecutive days; or

                    (f)  the commencement by the Company of a voluntary
               case or proceeding under any applicable Federal or State
               bankruptcy, insolvency, reorganization or other similar law
               or of any other case or proceeding to be adjudicated a
               bankrupt or insolvent, or the consent by it to the entry of
               a decree or order for relief in respect of the Company in a
               case or proceeding under any applicable Federal or State
               bankruptcy, insolvency, reorganization or other similar law
               or to the commencement of any bankruptcy or insolvency case
               or proceeding against it, or the filing by it of a petition
               or answer or consent seeking reorganization or relief under
               any applicable Federal or State law, or the consent by it to
               the filing of such petition or to the appointment of or
               taking possession by a custodian, receiver, liquidator,
               assignee, trustee, sequestrator or similar official of the
               Company or of any substantial part of its property, or the
               making by it of an assignment for the benefit of creditors,
               or the admission by it in writing of its inability to pay
               its debts generally as they become due, or the authorization
               of such action by the Board of Directors.

                    (g)  so long as the Trustee shall hold any Outstanding
               Class A Bonds which were delivered to the Trustee in
               connection with the authentication and delivery of
               Securities which remain Outstanding hereunder, the
               occurrence of a matured event of default under the Class A
               Mortgage under which such Class A Bonds were authenticated
               and delivered (other than any such matured event of default
               which (i) is of similar kind or character to the Event of
               Default described in clause (c) above and (ii) has not
               resulted in the acceleration of the Class A Bonds
               Outstanding under such Class A Mortgage); provided, however,
               that, anything in this Indenture to the contrary
               notwithstanding, the waiver or cure of any such event of
               default under such Class A Mortgage and the rescission and
               annulment of the consequences thereof under such Class A
               Mortgage shall constitute a cure of the corresponding Event
               of Default under this Indenture and a rescission and
               annulment of the consequences thereof.

          SECTION 702.  ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

                    If an Event of Default shall have occurred and be
          continuing, then in every such case the Trustee or the Holders of
          not less than thirty-three percentum (33%) in principal amount of
          the Securities then Outstanding may declare the principal amount
          (or, if any of the Securities are Discount Securities, such
          portion of the principal amount of such Securities as may be
          specified in the terms thereof as contemplated by Section 301) of
          all of the Securities then Outstanding to be due and payable
          immediately, by a notice in writing to the Company (and to the
          Trustee if given by Holders), and upon such declaration such
          principal amount (or specified amount), together with premium, if
          any, and accrued interest, if any, thereon, shall become
          immediately due and payable, all subject, however, in the case of
          an Event of Default described in clause (g) of Section 701, to
          the proviso contained in such clause (g).

                    At any time after such a declaration of acceleration of
          the maturity of the Securities then Outstanding shall have been
          made, but before a judgment or decree for payment of the money
          due shall have been obtained by the Trustee as provided in this
          Article, such declaration and its consequences shall, without
          further act, be deemed to have been rescinded and annulled, if

                         (a)  the Company shall have paid or deposited with
                    the Trustee a sum sufficient to pay

                              (i)  all overdue interest, if any, on all
                         Securities then Outstanding;

                              (ii)  the principal of and premium, if any,
                         on any Securities then Outstanding which have
                         become due otherwise than by such declaration of
                         acceleration and interest, if any, thereon at the
                         rate or rates prescribed therefor in such
                         Securities;

                              (iii)  interest, if any, upon overdue
                         interest, if any, at the rate or rates prescribed
                         therefor in such Securities, to the extent that
                         payment of such interest is lawful; and

                              (iv)  all amounts due to the Trustee under
                         Section 807; and

                         (b)  all Events of Default, other than the non-
                    payment of the principal of Securities of such series
                    which shall have become due solely by such declaration
                    of acceleration, shall have been cured or waived as
                    provided in Section 713.

          No such rescission shall affect any subsequent Event of Default
          or impair any right consequent thereon.

          SECTION 703.  COLLECTION OF INDEBTEDNESS AND SUITS FOR
          ENFORCEMENT BY TRUSTEE.

                    If an Event of Default described in clause (a) or (b)
          of Section 701 shall have occurred and be continuing, the Company
          shall, upon demand of the Trustee, pay to it, for the benefit of
          the Holders of the Securities with respect to which such Event of
          Default shall have occurred, the whole amount then due and
          payable on such Securities for principal and premium, if any, and
          interest, if any, and, in addition thereto, such further amount
          as shall be sufficient to cover any amounts due to the Trustee
          under Section 807.

                    If the Company shall fail to pay such amounts forthwith
          upon such demand, the Trustee, in its own name and as trustee of
          an express trust, may institute a judicial proceeding for the
          collection of the sums so due and unpaid, may prosecute such
          proceeding to judgment or final decree and may enforce the same
          against the Company or any other obligor upon such Securities and
          collect the moneys adjudged or decreed to be payable in the
          manner provided by law out of the property of the Company or any
          other obligor upon such Securities, wherever situated.

                    If an Event of Default shall have occurred and be
          continuing, the Trustee may in its discretion proceed to protect
          and enforce its rights and the rights of the Holders of the
          Securities then Outstanding by such appropriate judicial
          proceedings as the Trustee shall deem most effectual to protect
          and enforce any such rights, whether for the specific enforcement
          of any covenant or agreement in this Indenture or in aid of the
          exercise of any power granted herein, or to enforce any other
          proper remedy.

          SECTION 704.  APPLICATION OF MONEY COLLECTED.

                    Any money collected by the Trustee pursuant to this
          Article shall be applied in the following order, to the extent
          permitted by law, at the date or dates fixed by the Trustee and,
          in case of the distribution of such money on account of principal
          or premium, if any, or interest, if any, upon presentation of the
          Securities and the notation thereon of the payment if only
          partially paid and upon surrender thereof if fully paid:

                      FIRST:  To the payment of all amounts due the Trustee
               under Section 807;

                      SECOND:  To the payment of the whole amount then due
               and unpaid upon the Outstanding Securities for principal and
               premium, if any, and interest, if any, in respect of which
               or for the benefit of which such money has been collected;
               and in case such proceeds shall be insufficient to pay in
               full the whole amount so due and unpaid upon such
               Securities, then to the payment of such principal and
               interest, if any, thereon without any preference or
               priority, ratably according to the aggregate amount so due
               and unpaid, with any balance then remaining to the payment
               of premium, if any, and, if so specified as contemplated by
               Section 301 with respect to the Securities of any series, or
               any Tranche thereof, interest, if any, on overdue premium,
               if any, and overdue interest, if any, ratably as aforesaid,
               all to the extent permitted by applicable law;

                      THIRD:  To the payment of the remainder, if any, to
               the Company or to whomsoever may be lawfully entitled to
               receive the same or as a court of competent jurisdiction may
               direct.

          SECTION 705.  TRUSTEE MAY FILE PROOFS OF CLAIM.

                    In case of the pendency of any receivership,
          insolvency, liquidation, bankruptcy, reorganization, arrangement,
          adjustment, composition or other judicial proceeding relative to
          the Company or any other obligor upon the Securities or the
          property of the Company or of such other obligor or their
          creditors, the Trustee (irrespective of whether the principal of
          the Securities shall then be due and payable as therein expressed
          or by declaration or otherwise and irrespective of whether the
          Trustee shall have made any demand on the Company for the payment
          of overdue principal or interest) shall be entitled and
          empowered, by intervention in such proceeding or otherwise,

                    (a)  to file and prove a claim for the whole amount of
               principal, premium, if any, and interest, if any, owing and
               unpaid in respect of the Securities and to file such other
               papers or documents as may be necessary or advisable in
               order to have the claims of the Trustee (including any claim
               for amounts due to the Trustee under Section 807) and of the
               Holders allowed in such judicial proceeding, and

                    (b)  to collect and receive any moneys or other
               property payable or deliverable on any such claims and to
               distribute the same;

          and any custodian, receiver, assignee, trustee, liquidator,
          sequestrator or other similar official in any such judicial
          proceeding is hereby authorized by each Holder to make such
          payments to the Trustee and, in the event that the Trustee shall
          consent to the making of such payments directly to the Holders,
          to pay to the Trustee any amounts due it under Section 807.

                    Nothing herein contained shall be deemed to authorize
          the Trustee to authorize or consent to or accept or adopt on
          behalf of any Holder any plan of reorganization, arrangement,
          adjustment or composition affecting the Securities or the rights
          of any Holder thereof or to authorize the Trustee to vote in
          respect of the claim of any Holder in any such proceeding.

          SECTION 706.  TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF
          SECURITIES.

                    All rights of action and claims under this Indenture or
          on the Securities may be prosecuted and enforced by the Trustee
          without the possession of any of the Securities or the production
          thereof in any proceeding relating thereto, and any such
          proceeding instituted by the Trustee shall be brought in its own
          name as trustee of an express trust, and any recovery of judgment
          shall, after provision for the payment of the reasonable
          compensation, expenses, disbursements and advances of the
          Trustee, its agents and counsel, be for the ratable benefit of
          the Holders in respect of which such judgment has been recovered.

          SECTION 707.  LIMITATION ON SUITS.

                    No Holder shall have any right to institute any
          proceeding, judicial or otherwise, with respect to this
          Indenture, or for the appointment of a receiver or trustee, or
          for any other remedy hereunder, unless:

                    (a)  such Holder shall have previously given written
               notice to the Trustee of a continuing Event of Default;

                    (b)  the Holders of a majority in aggregate principal
               amount of the Securities then Outstanding shall have made
               written request to the Trustee to institute proceedings in
               respect of such Event of Default in its own name as Trustee
               hereunder;

                    (c)  such Holder or Holders shall have offered to the
               Trustee reasonable indemnity against the costs, expenses and
               liabilities to be incurred in compliance with such request;

                    (d)  the Trustee for sixty (60) days after its receipt
               of such notice, request and offer of indemnity shall have
               failed to institute any such proceeding; and

                    (e)  no direction inconsistent with such written
               request shall have been given to the Trustee during such
               sixty (60) day period by the Holders of a majority in
               aggregate principal amount of the Securities then
               Outstanding.

          it being understood and intended that no one or more of the
          Holders of any Securities shall have any right in any manner
          whatever by virtue of, or by availing of, any provision of this
          Indenture to affect, disturb or prejudice the rights of any other
          Holders or to obtain or to seek to obtain priority or preference
          over any other Holders or to enforce any right under this
          Indenture, except in the manner herein provided and for the equal
          and ratable benefit of all Holders.

          SECTION 708.  UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE
          PRINCIPAL, PREMIUM AND INTEREST.

                    Notwithstanding any other provision in this Indenture,
          the Holder of any Security shall have the right, which is
          absolute and unconditional, to receive payment of the principal
          of and premium, if any, and (subject to Section 307) interest, if
          any, on such Security on the Stated Maturity or Maturities
          expressed in such Security (or, in the case of redemption, on the
          Redemption Date) and to institute suit for the enforcement of any
          such payment, and such rights shall not be impaired without the
          consent of such Holder.

          SECTION 709.  RESTORATION OF RIGHTS AND REMEDIES.

                    If the Trustee or any Holder has instituted any
          proceeding to enforce any right or remedy under this Indenture
          and such proceeding shall have been discontinued or abandoned for
          any reason, or shall have been determined adversely to the
          Trustee or to such Holder, then and in every such case, subject
          to any determination in such proceeding, the Company, the Trustee
          and such Holder shall be restored severally and respectively to
          their former positions hereunder and thereafter all rights and
          remedies of the Trustee and such Holder shall continue as though
          no such proceeding had been instituted.

          SECTION 710.  RIGHTS AND REMEDIES CUMULATIVE.

                    Except as otherwise provided in the last paragraph of
          Section 306, no right or remedy herein conferred upon or reserved
          to the Trustee or to the Holders is intended to be exclusive of
          any other right or remedy, and every right and remedy shall, to
          the extent permitted by law, be cumulative and in addition to
          every other right and remedy given hereunder or now or hereafter
          existing at law or in equity or otherwise.  The assertion or
          employment of any right or remedy hereunder, or otherwise, shall
          not prevent the concurrent assertion or employment of any other
          appropriate right or remedy.

          SECTION 711.  DELAY OR OMISSION NOT WAIVER.

                    No delay or omission of the Trustee or of any Holder to
          exercise any right or remedy accruing upon any Event of Default
          shall impair any such right or remedy or constitute a waiver of
          any such Event of Default or an acquiescence therein.  Every
          right and remedy given by this Article or by law to the Trustee
          or to the Holders may be exercised from time to time, and as
          often as may be deemed expedient, by the Trustee or by the
          Holders, as the case may be.

          SECTION 712.  CONTROL BY HOLDERS OF SECURITIES.

                    If an Event of Default shall have occurred and be
          continuing, the Holders of a majority in principal amount of the
          Securities then Outstanding shall have the right to direct the
          time, method and place of conducting any proceeding for any
          remedy available to the Trustee, or exercising any trust or power
          conferred on the Trustee with respect to the Securities of such
          series; provided, however, that 

                    (a)  such direction shall not be in conflict with any
               rule of law or with this Indenture, and could not involve
               the Trustee in personal liability in circumstances where
               indemnity would not, in the Trustee's sole discretion, be
               adequate, 

                    (b)  the Trustee shall not determine that the action so
               directed would be unjustly prejudicial to the Holders not
               taking part in such direction, and

                    (c)  the Trustee may take any other action deemed
               proper by the Trustee which is not inconsistent with such
               direction.

          SECTION 713.  WAIVER OF PAST DEFAULTS.

                    The Holders of a majority in principal amount of the
          Securities then Outstanding may on behalf of the Holders of all
          the Securities then Outstanding waive any past default hereunder
          and its consequences, except a default

                    (a)  in the payment of the principal of or premium, if
               any, or interest, if any, on any Security then Outstanding,
               or

                    (b)  in respect of a covenant or provision hereof which
               under Section 1102 cannot be modified or amended without the
               consent of the Holder of each Outstanding Security of any
               series or Tranche affected.

                    Upon any such waiver, such default shall cease to
          exist, and any and all Events of Default arising therefrom shall
          be deemed to have been cured, for every purpose of this
          Indenture; but no such waiver shall extend to any subsequent or
          other default or impair any right consequent thereon.

          SECTION 714.  UNDERTAKING FOR COSTS.

                    The Company and the Trustee agree, and each Holder by
          its acceptance of a Security shall be deemed to have agreed, that
          any court may in its discretion require, in any suit for the
          enforcement of any right or remedy under this Indenture, or in
          any suit against the Trustee for any action taken, suffered or
          omitted by it as Trustee, the filing by any party litigant in
          such suit of an undertaking to pay the costs of such suit, and
          that such court may in its discretion assess reasonable costs,
          including reasonable attorneys' fees, against any party litigant
          in such suit, having due regard to the merits and good faith of
          the claims or defenses made by such party litigant, all in the
          manner, to the extent and except as provided in the Trust
          Indenture Act; but the provisions of this Section shall not apply
          to any suit instituted by the Company, to any suit instituted by
          the Trustee, to any suit instituted by any Holder, or group of
          Holders, holding in the aggregate more than ten percentum (10%)
          in aggregate principal amount of the Securities then Outstanding,
          or to any suit instituted by any Holder for the enforcement of
          the payment of the principal of or premium, if any, or interest,
          if any, on any Security on or after the Stated Maturity or
          Maturities expressed in such Security (or, in the case of
          redemption, on or after the Redemption Date).

          SECTION 715.  WAIVER OF STAY OR EXTENSION LAWS.

                    To the full extent that it may lawfully so agree, the
          Company shall not at any time set up, claim or otherwise seek to
          take the benefit or advantage of any stay or extension law, now
          or hereafter in effect, in order to prevent or hinder the
          enforcement of this Indenture; and the Company, for itself and
          all who may claim under it, so far as it or they now or hereafter
          may lawfully do so, hereby waives the benefit of all such laws.  

          SECTION 716.  DEFAULTS UNDER CLASS A MORTGAGES.

                    In addition to every other right and remedy provided
          herein, the Trustee may (but shall not be obligated to) exercise
          any right or remedy available to the Trustee in its capacity as
          owner and holder of Class A Bonds which arises as a result of a
          default or matured event of default under any Class A Mortgage,
          whether or not an Event of Default shall then have occurred and
          be continuing.


                                    ARTICLE EIGHT

                                     THE TRUSTEE

          SECTION 801.  CERTAIN DUTIES AND RESPONSIBILITIES.

                    (a)  Except during the continuance of an Event of
          Default,

                         (i)  the Trustee undertakes to perform such
                    series, such duties and only such duties as are
                    specifically set forth in this Indenture, and no
                    implied covenants or obligations shall be read into
                    this Indenture against the Trustee; and

                         (ii) in the absence of bad faith on its part, the
                    Trustee may conclusively rely, as to the truth of the
                    statements and the correctness of the opinions
                    expressed therein, upon certificates or opinions
                    furnished to the Trustee and conforming to the
                    requirements of this Indenture; but in the case of any
                    such certificates or opinions which by any provisions
                    hereof are specifically required to be furnished to the
                    Trustee, the Trustee shall be under a duty to examine
                    the same to determine whether or not they conform to
                    the requirements of this Indenture.

                    (b)  In case an Event of Default shall have occurred
          and be continuing, the Trustee shall exercise such of the rights
          and powers vested in it by this Indenture, and use the same
          degree of care and skill in their exercise, as a prudent man
          would exercise or use under the circumstances in the conduct of
          his own affairs.

                    (c)  No provision of this Indenture shall be construed
          to relieve the Trustee from liability for its own negligent
          action, its own negligent failure to act, or its own willful
          misconduct, except that:

                         (i)  this subsection shall not be construed to
                    limit the effect of subsection (a) of this Section;

                         (ii) the Trustee shall not be liable for any error
                    of judgment made in good faith by a Responsible
                    Officer, unless it shall be proved that the Trustee was
                    negligent in ascertaining the pertinent facts;

                         (iii)     the Trustee shall not be liable with
                    respect to any action taken or omitted to be taken by
                    it in good faith in accordance with the direction of
                    the Holders of a majority in principal amount of the
                    Securities then Outstanding, as provided herein,
                    relating to the time, method and place of conducting
                    any proceeding for any remedy available to the Trustee,
                    or exercising any trust or power conferred upon the
                    Trustee, under this Indenture with respect to the
                    Securities of such series; and

                         (iv) no provision of this Indenture shall require
                    the Trustee to expend or risk its own funds or
                    otherwise incur any financial liability in the
                    performance of any of its duties hereunder, or in the
                    exercise of any of its rights or powers, if it shall
                    have reasonable grounds for believing that repayment of
                    such funds or adequate indemnity against such risk or
                    liability is not reasonably assured to it.

                    (d)  Whether or not therein expressly so provided,
          every provision of this Indenture relating to the conduct or
          affecting the liability of or affording protection to the Trustee
          shall be subject to the provisions of this Section.

          SECTION 802.  NOTICE OF DEFAULTS.

                    The Trustee shall give the Holders notice of any
          default hereunder in the manner and to the extent required to do
          so by the Trust Indenture Act, unless such default shall have
          been cured or waived; provided, however, that in the case of any
          default of the character specified in Section 701(c), no such
          notice to Holders shall be given until at least seventy-five (75)
          days after the occurrence thereof; and provided, further, that,
          subject to the provisions of Section 801, the Trustee shall not
          be deemed to have knowledge of such default unless either (i) a
          Responsible Officer of the Trustee shall have actual knowledge of
          such default or (ii) the Trustee shall have received written
          notice thereof from the Company or any Holder or, in the case of
          a default described in Section 701(d), from the holder of any
          indebtedness or from the trustee under any mortgage, indenture or
          other instrument referred to in such Section.  For the purpose of
          this Section, the term "default" means any event which is, or
          after notice or lapse of time, or both, would become, an Event of
          Default.  The Trustee shall give to the trustee under each Class
          A Mortgage a copy of each notice of default given to the Holders
          pursuant to this Section.  In addition, the Trustee shall give to
          the Holders copies of each notice of default under any Class A
          Mortgage given to the Trustee in its capacity as owner and holder
          of Class A Bonds delivered thereunder.

          SECTION 803.  CERTAIN RIGHTS OF TRUSTEE.

                    Subject to the provisions of Section 801 and to the
          applicable provisions of the Trust Indenture Act:

                    (a)  the Trustee may rely and shall be protected in
               acting or refraining from acting upon any resolution,

               request, direction, consent, order, bond, debenture, note,
               other evidence of indebtedness or other paper or document

                    (b)  any request, direction or act of the Company
               mentioned herein shall be sufficiently evidenced by a
               Company Request or Company Order, or as otherwise expressly
               provided herein, and any resolution of the Board of
               Directors may be sufficiently evidenced by a Board
               Resolution;

                    (c)  whenever in the administration of this Indenture
               the Trustee shall deem it desirable that a matter be proved
               or established prior to taking, suffering or omitting any
               action hereunder, the Trustee (unless other evidence is
               specifically prescribed herein) may, in the absence of bad
               faith on its part, rely upon an Officer's Certificate;

                    (d)  the Trustee may consult with counsel and the
               written advice of such counsel or any Opinion of Counsel
               shall be full and complete authorization and protection in
               respect of any action taken, suffered or omitted by it
               hereunder in good faith and in reliance thereon;

                    (e)  the Trustee shall be under no obligation to
               exercise any of the rights or powers vested in it by this
               Indenture at the request or direction of any Holder pursuant
               to this Indenture, unless such Holder shall have offered to
               the Trustee reasonable security or indemnity against the
               costs, expenses and liabilities which might be incurred by
               it  complying with such request or direction;

                    (f)  the Trustee shall not be bound to make any
               investigation into the facts or matters stated in any
               resolution, certificate, statement, instrument, opinion,

               debenture, note, other evidence of indebtedness or other
               paper or document, but the Trustee, in its discretion, may
               make such further inquiry or investigation into such facts
               or matters as it may see fit, and, if the Trustee shall
               determine to make such further inquiry or investigation, it
               shall (subject to applicable legal requirements) be entitled
               to examine, during normal business hours, the books, records
               and premises of the Company, personally or by agent or
               attorney;

                    (g)  the Trustee may execute any of the trusts or
               powers hereunder or perform any duties hereunder either
               directly or by or through agents or attorneys and the
               Trustee shall not be responsible for any misconduct or
               negligence on the part of any agent or attorney appointed
               with due care by it hereunder; and

                    (h)  the Trustee shall not be charged with knowledge of
               any Event of Default unless either (i) a Responsible Officer
               of the Trustee shall have actual knowledge of the Event of
               Default or (ii) written notice of such Event of Default
               shall have been given to the Trustee by the Company, any
               other obligor on such Securities or by any Holder of such
               Securities or, in the case of a default described in Section
               701(d), from the holder of any indebtedness or from the
               trustee under any mortgage, indenture or other instrument
               referred to in such Section.

          SECTION 804.  NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF
          SECURITIES.

                    The recitals contained herein and in the Securities
          (except the Trustee's certificates of authentication) shall be
          taken as the statements of the Company, and neither the Trustee
          nor any Authenticating Agent assumes any responsibility for their
          correctness.  The Trustee makes no representations as to the
          validity or sufficiency of this Indenture or of the Securities. 
          Neither the Trustee nor any Authenticating Agent shall be
          accountable for the use or application by the Company of
          Securities or the proceeds thereof.

          SECTION 805.  MAY HOLD SECURITIES.

                    Each of the Trustee, any Authenticating Agent, any
          Paying Agent, any Security Registrar or any other agent of the
          Company or the Trustee, in its individual or any other capacity,
          may become the owner or pledgee of Securities and, subject to
          Sections 808 and 813, may otherwise deal with the Company with
          the same rights it would have if it were not such Trustee,
          Authenticating Agent, Paying Agent, Security Registrar or other
          agent.

          SECTION 806.  MONEY HELD IN TRUST.

                    Money held by the Trustee in trust hereunder need not
          be segregated from other funds, except to the extent required by
          law.  The Trustee shall be under no liability for interest on or
          investment of any money received by it hereunder except as
          expressly provided herein or otherwise agreed with, and for the
          sole benefit of, the Company.

          SECTION 807.  COMPENSATION AND REIMBURSEMENT.

                    The Company shall

                    (a)  pay to the Trustee from time to time reasonable
               compensation for all services rendered by it hereunder
               (which compensation shall not be limited by any provision of
               law in regard to the compensation of a trustee of an express
               trust);

                    (b)  except as otherwise expressly provided herein,
               reimburse the Trustee upon its request for all reasonable
               expenses, disbursements and advances reasonably incurred or
               made by the Trustee in accordance with any provision of this
               Indenture (including the reasonable compensation and the
               expenses and disbursements of its agents and counsel),
               except to the extent that any such expense, disbursement or
               advance may be attributable to its negligence, wilful
               misconduct or bad faith; and

                    (c)  indemnify the Trustee and hold it harmless from
               and against any loss, liability or expense reasonably
               incurred by it arising out of or in connection with the
               acceptance or administration of the trust or trusts
               hereunder or the performance of its duties hereunder,
               including the reasonable costs and expenses of defending
               itself against any claim or liability in connection with the
               exercise or performance of any of its powers or duties
               hereunder, except to the extent any such loss, liability or
               expense may be attributable to its negligence, wilful
               misconduct or bad faith.

                    As security for the performance of the obligations of
          the Company under this Section, the Trustee shall have a lien
          prior to the Securities upon all property and funds held or
          collected by the Trustee as such other than property and funds
          held in trust under Section 603 (except moneys payable to the
          Company as provided in Section 603).  "Trustee" for purposes of
          this Section shall include any predecessor Trustee; provided,
          however, that the negligence, wilful misconduct or bad faith of
          any Trustee hereunder shall not affect the rights of any other
          Trustee hereunder.

          SECTION 808.  DISQUALIFICATION; CONFLICTING INTERESTS.

                    If the Trustee shall have or acquire any conflicting
          interest within the meaning of the Trust Indenture Act, it shall
          either eliminate such conflicting interest or resign to the
          extent, in the manner and with the effect, and subject to the
          conditions, provided in the Trust Indenture Act and this
          Indenture.  For purposes of Section 310(b)(1) of the Trust
          Indenture Act and to the extent permitted thereby, the Trustee,
          in its capacity as trustee in respect of the Securities of any
          series, shall not be deemed to have a conflicting interest
          arising from its capacity as trustee in respect of the Securities
          of any other series.  

          SECTION 809.  CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

                    There shall at all times be a Trustee hereunder which
          shall be

                    (a)  a corporation organized and doing business under
               the laws of the United States, any State or Territory
               thereof or the District of Columbia, authorized under such
               laws to exercise corporate trust powers, having a combined
               capital and surplus of at least Ten Million Dollars
               ($10,000,000) and subject to supervision or examination by
               Federal, State, Territorial or District of Columbia
               authority, or

                    (b)  if and to the extent permitted by the Commission
               by rule, regulation or order upon application, a corporation
               or other Person organized and doing business under the laws
               of a foreign government, authorized under such laws to
               exercise corporate trust powers, having a combined capital
               and surplus of at least Fifty Million Dollars ($50,000,000)
               or the Dollar equivalent of the applicable foreign currency
               and subject to supervision or examination by authority of
               such foreign government or a political subdivision thereof
               substantially equivalent to supervision or examination
               applicable to United States institutional trustees,

          and, in either case, qualified and eligible under this Article
          and the Trust Indenture Act.  If such corporation publishes
          reports of condition at least annually, pursuant to law or to the
          requirements of such supervising or examining authority, then for
          the purposes of this Section, the combined capital and surplus of
          such corporation shall be deemed to be its combined capital and
          surplus as set forth in its most recent report of condition so
          published.  If at any time the Trustee shall cease to be eligible
          in accordance with the provisions of this Section or the Trust
          Indenture Act, it shall resign immediately in the manner and with
          the effect hereinafter specified in this Article.

          SECTION 810.  RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

                    (a)  No resignation or removal of the Trustee and no
          appointment of a successor Trustee pursuant to this Article shall
          become effective until the acceptance of appointment by the
          successor Trustee in accordance with the applicable requirements
          of Section 811.

                    (b)  The Trustee may resign at any time by giving
          written notice thereof to the Company.  If the instrument of
          acceptance by a successor Trustee required by Section 811 shall
          not have been delivered to the Trustee within thirty (30) days
          after the giving of such notice of resignation, the resigning
          Trustee may petition any court of competent jurisdiction for the
          appointment of a successor Trustee.

                    (c)  The Trustee may be removed at any time by Act of
          the Holders of a majority in principal amount of the Securities
          then Outstanding delivered to the Trustee and to the Company.

                    (d)  If at any time:

                         (i)  the Trustee shall fail to comply with Section
                    808 after written request therefor by the Company or by
                    any Holder who has been a bona fide Holder for at least
                    six months, or

                         (ii)  the Trustee shall cease to be eligible under
                    Section 809 or Section 310(a) of the Trust Indenture
                    Act and shall fail to resign after written request
                    therefor by the Company or by any such Holder, or

                         (iii)  the Trustee shall become incapable of
                    acting or shall be adjudged a bankrupt or insolvent or
                    a receiver of the Trustee or of its property shall be
                    appointed or any public officer shall take charge or
                    control of the Trustee or of its property or affairs
                    for the purpose of rehabilitation, conservation or
                    liquidation,

          then, in any such case, (x) the Company may remove the Trustee
          with respect to all Securities or (y) subject to Section 714, any
          Holder who has been a bona fide Holder for at least six (6)
          months may, on behalf of itself and all others similarly
          situated, petition any court of competent jurisdiction for the
          removal of the Trustee and the appointment of a successor Trustee
          or Trustees.

                    (e)  If the Trustee shall resign, be removed or become
          incapable of acting, or if a vacancy shall occur in the office of
          Trustee for any cause (other than as contemplated in clause (y)
          in subsection (d) of this Section), the Company shall take prompt
          steps to appoint a successor Trustee or Trustees and shall comply
          with the applicable requirements of Section 811.  If, within one
          (1) year after such resignation, removal or incapability, or the
          occurrence of such vacancy, a successor Trustee shall be
          appointed by Act of the Holders of a majority in principal amount
          of the Securities then Outstanding delivered to the Company and
          the retiring Trustee, the successor Trustee so appointed shall,
          forthwith upon its acceptance of such appointment in accordance
          with the applicable requirements of Section 811, become the
          successor Trustee and to that extent supersede the successor
          Trustee appointed by the Company.  If no successor Trustee shall
          have been so appointed by the Company or the Holders and accepted
          appointment in the manner required by Section 811, any Holder who
          has been a bona fide Holder of a Security for at least six (6)
          months may, on behalf of itself and all others similarly
          situated, petition any court of competent jurisdiction for the
          appointment of a successor Trustee.

                    (f)  So long as no event which is, or after notice or
          lapse of time, or both, would become, an Event of Default shall
          have occurred and be continuing, if the Company shall have
          delivered to the Trustee (i) an instrument executed by an
          Authorized Officer appointing a successor Trustee or Trustees,
          effective as of a date specified therein, and (ii) an instrument
          of acceptance of such appointment, effective as of such date, by
          such successor Trustee or Trustees in accordance with Section
          811, the Trustee or Trustees shall be deemed to have resigned as
          contemplated in subsection (b) of this Section, the successor
          Trustee or Trustees shall be deemed to have been appointed
          pursuant to subsection (e) of this Section and such appointment
          shall be deemed to have been accepted as contemplated in Section
          811, all as of such date, and all other provisions of this
          Section and Section 811 shall be applicable to such resignation,
          appointment and acceptance except to the extent inconsistent with
          this subsection (f).

                    (g)  The Company shall give notice of each resignation
          and each removal of the Trustee and each appointment of a
          successor Trustee to all Holders of Securities.  Each notice
          shall include the name of the successor Trustee and the address
          of its corporate trust office.

          SECTION 811.  ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

                    (a)  In case of the appointment hereunder of a
          successor Trustee, every such successor Trustee so appointed
          shall execute, acknowledge and deliver to the Company and to the
          retiring Trustee an instrument accepting such appointment, and
          thereupon the resignation or removal of the retiring Trustee
          shall become effective and such successor Trustee, without any
          further act, shall become vested with all the rights, powers,
          trusts and duties of the retiring Trustee; but, on the request of
          the Company or the successor Trustee, such retiring Trustee
          shall, upon payment of all sums owed to it, execute and deliver
          an instrument transferring to such successor Trustee all the
          rights, powers and trusts of the retiring Trustee and shall duly
          assign, transfer and deliver to such successor Trustee all
          property and money held by such retiring Trustee hereunder.

                    (b)  Upon reasonable request of any such successor
          Trustee, the Company shall execute instruments to more fully and
          certainly vest in and confirm to such successor Trustee all
          rights, powers and trusts referred to in subsection (a) of this
          Section.

                    (c)  No successor Trustee shall accept its appointment
          unless at the time of such acceptance such successor Trustee
          shall be qualified and eligible under this Article.

          SECTION 812.  MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO
          BUSINESS.

                    Any corporation into which the Trustee may be merged or
          converted or with which it may be consolidated, or any
          corporation resulting from any merger, conversion or
          consolidation to which the Trustee shall be a party, or any
          corporation succeeding to all or substantially all the corporate
          trust business of the Trustee, shall be the successor of the
          Trustee hereunder, provided such corporation shall be otherwise
          qualified and eligible under this Article, without the execution
          or filing of any paper or any further act on the part of any of
          the parties hereto.  In case any Securities shall have been
          authenticated, but not delivered, by the Trustee then in office,
          any successor by merger, conversion or consolidation to such
          authenticating Trustee may adopt such authentication and deliver
          the Securities so authenticated with the same effect as if such
          successor Trustee had itself authenticated such Securities.

          SECTION 813.  PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

                    If the Trustee shall be or become a creditor of the
          Company or any other obligor upon the Securities (other than by
          reason of a relationship described in Section 311(b) of the Trust
          Indenture Act), the Trustee shall be subject to any and all
          applicable provisions of the Trust Indenture Act regarding the
          collection of claims against the Company or such other obligor. 
          For purposes of Section 311(b) of the Trust Indenture Act:

                    (a)  the term "CASH TRANSACTION" means any transaction
               in which full payment for goods or securities sold is made
               within seven days after delivery of the goods or securities
               in currency or in checks or other orders drawn upon banks or
               bankers and payable upon demand; and

                    (b)  the term "SELF-LIQUIDATING PAPER" means any draft,
               bill of exchange, acceptance or obligation which is made,
               drawn, negotiated or incurred by the Company or such obligor
               for the purpose of financing the purchase, processing,
               manufacturing, shipment, storage or sale of goods, wares or
               merchandise and which is secured by documents evidencing
               title to, possession of, or a lien upon, the goods, wares or
               merchandise or the receivables or proceeds arising from the
               sale of the goods, wares or merchandise previously
               constituting the security, provided the security is received
               by the Trustee simultaneously with the creation of the
               creditor relationship with the Company or such obligor
               arising from the making, drawing, negotiating or incurring
               of the draft, bill of exchange, acceptance or obligation.

          SECTION 814.  APPOINTMENT OF AUTHENTICATING AGENT.

                    The Trustee may appoint an Authenticating Agent or
          Agents with respect to the Securities of one or more series, or
          any Tranche thereof, which shall be authorized to act on behalf
          of the Trustee to authenticate Securities of such series or
          Tranche issued upon original issuance, exchange, registration of
          transfer or partial redemption thereof or pursuant to Section
          306, and Securities so authenticated shall be entitled to the
          benefits of this Indenture and shall be valid and obligatory for
          all purposes as if authenticated by the Trustee hereunder. 
          Wherever reference is made in this Indenture to the
          authentication and delivery of Securities by the Trustee or the
          Trustee's certificate of authentication, such reference shall be
          deemed to include authentication and delivery on behalf of the
          Trustee by an Authenticating Agent and a certificate of
          authentication executed on behalf of the Trustee by an
          Authenticating Agent.  Each Authenticating Agent shall be
          acceptable to the Company and shall at all times be a corporation
          organized and doing business under the laws of the United States,
          any State or Territory thereof or the District of Columbia or the
          Commonwealth of Puerto Rico, authorized under such laws to act as
          Authenticating Agent, having a combined capital and surplus of
          not less than Ten Million Dollars ($10,000,000) and subject to
          supervision or examination by Federal or State authority.  If
          such Authenticating Agent publishes reports of condition at least
          annually, pursuant to law or to the requirements of said
          supervising or examining authority, then for the purposes of this
          Section, the combined capital and surplus of such Authenticating
          Agent shall be deemed to be its combined capital and surplus as
          set forth in its most recent report of condition so published. 
          If at any time an Authenticating Agent shall cease to be eligible
          in accordance with the provisions of this Section, such
          Authenticating Agent shall resign immediately in the manner and
          with the effect specified in this Section.

                    Any corporation into which an Authenticating Agent may
          be merged or converted or with which it may be consolidated, or
          any corporation resulting from any merger, conversion or
          consolidation to which such Authenticating Agent shall be a
          party, or any corporation succeeding to all or substantially all
          of the corporate agency or corporate trust business of an
          Authenticating Agent, shall continue to be an Authenticating
          Agent, provided such corporation shall be otherwise eligible
          under this Section, without the execution or filing of any paper
          or any further act on the part of the Trustee or the
          Authenticating Agent.

                    An Authenticating Agent may resign at any time by
          giving written notice thereof to the Trustee and to the Company. 
          The Trustee may at any time terminate the agency of an
          Authenticating Agent by giving written notice thereof to such
          Authenticating Agent and to the Company.  Upon receiving such a
          notice of resignation or upon such a termination, or in case at
          any time such Authenticating Agent shall cease to be eligible in
          accordance with the provisions of this Section, the Trustee may
          appoint a successor Authenticating Agent which shall be
          acceptable to the Company.  Any successor Authenticating Agent
          upon acceptance of its appointment hereunder shall become vested
          with all the rights, powers and duties of its predecessor
          hereunder, with like effect as if originally named as an
          Authenticating Agent.  No successor Authenticating Agent shall be
          appointed unless eligible under the provisions of this Section.

                    The Company agrees to pay to each Authenticating Agent
          from time to time reasonable compensation for its services under
          this Section.

                    The provisions of Sections 308, 804 and 805 shall be
          applicable to each Authenticating Agent.

                    If an appointment with respect to the Securities of one
          or more series, or any Tranche thereof, shall be made pursuant to
          this Section, the Securities of such series or Tranche may have
          endorsed thereon, in addition to the Trustee's certificate of
          authentication, an alternate certificate of authentication
          substantially in the following form:

                    This is one of the Securities of the series designated
          therein referred to in the within-mentioned Indenture.

                                                  ------------------------
                                                  As Trustee

                                                    As Authenticating Agent

                                                  By----------------------
                                                    Authorized Officer

                    If all of the Securities of a series may not be
          originally issued at one time, and if the Trustee does not have
          an office capable of authenticating Securities upon original
          issuance located in a Place of Payment where the Company wishes
          to have Securities of such series authenticated upon original
          issuance, the Trustee, if so requested by the Company in writing
          (which writing need not comply with Section 102 and need not be
          accompanied by an Opinion of Counsel), shall appoint, in
          accordance with this Section and in accordance with such
          procedures as shall be acceptable to the Trustee, an
          Authenticating Agent having an office in a Place of Payment
          designated by the Company with respect to such series of
          Securities.

                    Trustee an indenture supplemental hereto, in form
                    reasonably satisfactory to the Trustee, which contains
                    an assumption by such transferee of the due and
                    punctual payment of the principal of and premium, if

                         property;

                              (C) stating an amount equal to seventy
                         percent (70%) of the amount stated pursuant to
                         clause (B) above;

                              (D)  stating an amount equal to the aggregate
                         principal amount of the Securities then
                         Outstanding; and

                              (E)   stating that the amount stated pursuant
                         to clause (D) above does not exceed the amount
                         stated pursuant to clause (C) above; and

                         (iii)  the Company shall have delivered to the
                    Trustee an Officer's Certificate and an Opinion of
                    Counsel each of which shall state that such conveyance
                    or other transfer and such supplemental indenture
                    comply with this Section and that all conditions
                    precedent relating to such transactions provided for in
                    this Section and otherwise in this Indenture have been
                    complied with;

          then, upon the satisfaction of all such conditions,

                    (x)  the Company shall be released and discharged from
               all obligations and covenants under this Indenture and on
               and under all Securities then Outstanding (unless the
               Company shall have delivered to the Trustee an instrument in
               which it shall waive such release and discharge), and the
               Trustee shall acknowledge in writing that the Company has
               been so released and discharged; and

                    (y)  if the Company shall have been released and
               discharged as contemplated in clause (x) above, such
               transferee shall succeed to, and be substituted for, and may
               exercise every right and power of, the Company under this
               Indenture with the same effect as if such transferee had
               been named the "Company" herein; and without limiting the
               generality of the foregoing, such transferee shall be deemed
               a "Successor" for purposes of Section 1002 and for all other
               purposes of this Indenture. 

                    In assessing the fair value of such property so
          conveyed or otherwise transferred, an Expert may consider, among
          other things (a) the amount which would be likely to be obtained
          in an arm's-length transaction with respect to such property
          between an informed and willing buyer and an informed and willing
          seller, under no compulsion, respectively, to buy or sell, (b)
          the amount of investment with respect to such property which,
          together with a reasonable return thereon, would be likely to be
          recovered through ordinary business operations or otherwise, (c)
          the cost, accumulated depreciation and replacement cost with
          respect to such property and/or (d) any other relevant factors;
          provided, however, that (x) the fair value of property shall be
          determined without deduction for any mortgage, deed of trust,
          pledge, security interest, encumbrance, lease, reservation,
          restriction, servitude, charge or similar right or any other lien
          of any kind on such property and (y) the fair value to the
          transferee of any property shall not reflect any reduction
          relating to the fact that such property may be of less value to a
          Person which is not the owner or operator of the property or any
          portion thereof than to a Person which is such owner or operator. 
          Fair value may be determined, without physical inspection, by the
          use of accounting and engineering records and other data
          maintained by the Company or the transferee or otherwise
          available to the Expert certifying the same.

                               SUPPLEMENTAL INDENTURES

          SECTION 1101.  SUPPLEMENTAL INDENTURES WITHOUT CONSENT OF
          HOLDERS.

                    Without the consent of any Holders, the Company and the
          Trustee, at any time and from time to time, may enter into one or
          more indentures supplemental hereto, in form reasonably
          satisfactory to the Trustee, for any of the following purposes:

                         (a)  to evidence the succession of another Person
                    to the Company and the assumption by any such successor
                    of the covenants of the Company herein and in the
                    Securities, all as provided in Article Ten; or

                         (b)  to add one or more covenants of the Company
                    or other provisions for the benefit of all Holders or
                    for the benefit of the Holders of, or to remain in
                    effect only so long as there shall be Outstanding,
                    Securities of one or more specified series, or one or
                    more specified Tranches thereof, or to surrender any
                    right or power herein conferred upon the Company; or

                         (c)  to change or eliminate any provision of this
                    Indenture or to add any new provision to this
                    Indenture; provided, however, that if such change,
                    elimination or addition shall adversely affect the
                    interests of the Holders of Securities of any series or
                    Tranche in any material respect, such change,
                    elimination or addition shall become effective with
                    respect to such series or Tranche only when no Security
                    of such series or Tranche remains Outstanding; or

                         (d)  to provide additional collateral security for
                    the Securities; or

                         (e)  to establish the form or terms of Securities
                    of any series or Tranche as contemplated by Sections
                    201 and 301; or

                         (f)  to provide for the authentication and
                    delivery of bearer securities and coupons appertaining
                    thereto representing interest, if any, thereon and for
                    the procedures for the registration, exchange and
                    replacement thereof and for the giving of notice to,
                    and the solicitation of the vote or consent of, the
                    holders thereof, and for any and all other matters
                    incidental thereto; or

                         (g)  to evidence and provide for the acceptance of
                    appointment hereunder by a successor Trustee or by a
                    co-trustee or separate trustee; or

                         (h)  to provide for the procedures required to
                    permit the Company to utilize, at its option, a non-
                    certificated system of registration for all, or any
                    series or Tranche of, the Securities; or

                         (i)  to change any place or places where (1) the
                    principal of and premium, if any, and interest, if any,
                    on all or any series of Securities, or any Tranche
                    thereof, shall be payable, (2) all or any series of
                    Securities, or any Tranche thereof, may be surrendered
                    for registration of transfer, (3) all or any series of
                    Securities, or any Tranche thereof, may be surrendered
                    for exchange and (4) notices and demands to or upon the
                    Company in respect of all or any series of Securities,
                    or any Tranche thereof, and this Indenture may be
                    served; or

                         (j)  to cure any ambiguity, to correct or
                    supplement any provision herein which may be defective
                    or inconsistent with any other provision herein; or to
                    make any other changes to the provisions hereof or to
                    add other provisions with respect to matters or
                    questions arising under this Indenture, provided that
                    such other changes or additions shall not adversely
                    affect the interests of the Holders of Securities of
                    any series or Tranche in any material respect.

                    Without limiting the generality of the foregoing, if
          the Trust Indenture Act as in effect at the date of the execution
          and delivery of this Indenture or at any time thereafter shall be
          amended and

                         (x)  if any such amendment shall require one or
                    more changes to any provisions hereof or the inclusion
                    herein of any additional provisions, or shall by
                    operation of law be deemed to effect such changes or
                    incorporate such provisions by reference or otherwise,
                    this Indenture shall be deemed to have been amended so
                    as to conform to such amendment to the Trust Indenture
                    Act, and the Company and the Trustee may, without the
                    consent of any Holders, enter into an indenture
                    supplemental hereto to evidence such amendment hereof;
                    or

                         (y)  if any such amendment shall permit one or
                    more changes to, or the elimination of, any provisions
                    hereof which, at the date of the execution and delivery
                    hereof or at any time thereafter, are required by the
                    Trust Indenture Act to be contained herein or are
                    contained herein to reflect any provisions of the Trust
                    Indenture Act as in effect at such date, this Indenture
                    shall be deemed to have been amended to effect such
                    changes or elimination, and the Company and the Trustee
                    may, without the consent of any Holders, enter into an
                    indenture supplemental hereto to amend this Indenture
                    to effect such changes or elimination.

          SECTION 1102.  SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS.

                    Subject to the provisions of Section 1101, with the
          consent of the Holders of a majority in aggregate principal
          amount of the Securities of all series then Outstanding under
          this Indenture, considered as one class, by Act of said Holders
          delivered to the Company and the Trustee, the Company and the
          Trustee may enter into an indenture or indentures supplemental
          hereto for the purpose of adding any provisions to, or changing
          in any manner or eliminating any of the provisions of, this
          Indenture; provided, however, that if there shall be Securities
          of more than one series Outstanding hereunder and if a proposed
          supplemental indenture shall directly affect the rights of the
          Holders of Securities of one or more, but less than all, of such
          series, then the consent only of the Holders of a majority in
          aggregate principal amount of the Outstanding Securities of all
          series so directly affected, considered as one class, shall be
          required; and provided, further, that if the Securities of any
          series shall have been issued in more than one Tranche and if the
          proposed supplemental indenture shall directly affect the rights
          of the Holders of Securities of one or more, but less than all,
          of such Tranches, then the consent only of the Holders of a
          majority in aggregate principal amount of the Outstanding
          Securities of all Tranches so directly affected, considered as
          one class, shall be required; and provided, further, that no such
          supplemental indenture shall:

                         (a)  change the Stated Maturity of the principal
                    of, or any installment of principal of or interest on,
                    any Security other than pursuant to the terms thereof,
                    or reduce the principal amount thereof or the rate of
                    interest thereon (or the amount of any installment of
                    interest thereon) or change the method of calculating
                    such rate or reduce any premium payable thereon, or
                    reduce the amount of the principal of any Discount
                    Security that would be due and payable upon a
                    declaration of acceleration of the Maturity thereof
                    pursuant to Section 702, or change the coin or currency
                    (or other property), in which any Security or premium,
                    if any, or interest, if any, thereon is payable, or
                    impair the right to institute suit for the enforcement
                    of any such payment on or after the Maturity of any
                    Security, without, in any such case, the consent of the
                    Holder of such Security; or

                         (b)  permit the creation of any Lien ranking prior
                    to the Lien of this Indenture with respect to any Class
                    A Bond delivered to and held by the Trustee pursuant to
                    Article Three, or (except in accordance with the
                    provisions of Article Three) terminate a Lien of this
                    Indenture on any such Class A Bond or deprive the
                    Holders of the benefit of the Lien of this Indenture on
                    any Class A Bond, without, in any such case, the
                    consent of the Holders of all Securities then
                    Outstanding; or

                         (c)  reduce the percentage in principal amount of
                    the Outstanding Securities of any series, or any
                    Tranche thereof, the consent of the Holders of which is
                    required for any such supplemental indenture, or the
                    consent of the Holders of which is required for any
                    waiver of compliance with any provision of this
                    Indenture or of any default hereunder and its
                    consequences, or reduce the requirements of Section
                    1204 for quorum or voting, without, in any such case,
                    the consent of the Holder of each Outstanding Security
                    of such series or Tranche; or

                         (d)  modify any of the provisions of this Section,
                    Section 506 or Section 713 with respect to the
                    Securities of any series or any Tranche thereof (except
                    to increase the percentages in principal amount
                    referred to in this Section or such other Sections or
                    to provide that other provisions of this Indenture
                    cannot be modified or waived without the consent of the
                    Holders of all Securities of such series or Tranche)
                    without, in any such case, the consent of the Holder of
                    each Outstanding Security of such series or Tranche;
                    provided, however, that this clause shall not be deemed
                    to require the consent of any Holder with respect to
                    changes in the references to "the Trustee" and
                    concomitant changes in this Section, or the deletion of
                    this proviso, in accordance with the requirements of
                    Sections 811(b) and 1101(g).

                    A supplemental indenture which (x) changes or
          eliminates any covenant or other provision of this Indenture
          which has expressly been included solely for the benefit of the
          Holders of, or which is to remain in effect only so long as there
          shall be Outstanding, Securities of one or more specified series,
          or one or more Tranches thereof, or (y) modifies the rights of
          the Holders of Securities of such series or Tranches with respect
          to such covenant or other provision, shall be deemed not to
          affect the rights under this Indenture of the Holders of
          Securities of any other series or Tranche.

                    It shall not be necessary for any Act of Holders under
          this Section to approve the particular form of any proposed
          supplemental indenture, but it shall be sufficient if such Act
          shall approve the substance thereof.

               Anything in this Indenture to the contrary notwithstanding,
          if the Officer's Certificate, supplemental indenture or Board
          Resolution, as the case may be, establishing the Securities of
          any series or Tranche shall so provide, (a) the Holders of such
          Securities shall be deemed to have consented to a supplemental
          indenture containing the additions, changes or eliminations to or
          from the Indenture which shall be specified in such Officer's
          Certificate, supplemental indenture or Board Resolution
          establishing such series or Tranche, (b) no Act of such Holders
          shall be required to evidence such consent and (c) such consent
          may be counted in the determination of whether or not the Holders
          of the requisite principal amount of Securities shall have
          consented to such supplemental indenture.

          SECTION 1103.  EXECUTION OF SUPPLEMENTAL INDENTURES.

                    In executing, or accepting the additional trusts
          created by, any supplemental indenture permitted by this Article
          or the modifications thereby of the trusts created by this
          Indenture, the Trustee shall be entitled to receive, and (subject
          to Section 801) shall be fully protected in relying upon, an
          Opinion of Counsel stating that the execution of such
          supplemental indenture is authorized or permitted by this
          Indenture.  The Trustee may, but shall not be obligated to, enter
          into any such supplemental indenture which affects the Trustee's
          own rights, duties, immunities or liabilities under this
          Indenture or otherwise.

          SECTION 1104.  EFFECT OF SUPPLEMENTAL INDENTURES.

                    Upon the execution and delivery of any supplemental
          indenture under this Article this Indenture shall be modified in
          accordance therewith, and such supplemental indenture shall form
          a part of this Indenture for all purposes; and every Holder of
          Securities theretofore or thereafter authenticated and delivered
          hereunder shall be bound thereby.  Any supplemental indenture
          permitted by this Article may restate this Indenture in its
          entirety, and, upon the execution and delivery thereof, any such
          restatement shall supersede this Indenture as theretofore in
          effect for all purposes.

          SECTION 1105.  CONFORMITY WITH TRUST INDENTURE ACT.

                    Every supplemental indenture executed pursuant to this
          Article shall conform to the requirements of the Trust Indenture
          Act.

          SECTION 1106.  REFERENCE IN SECURITIES TO SUPPLEMENTAL
          INDENTURES.

                    Securities of any series, or any Tranche thereof,
          authenticated and delivered after the execution of any
          supplemental indenture pursuant to this Article may, and shall if
          required by the Trustee, bear a notation in form approved by the
          Trustee as to any matter provided for in such supplemental
          indenture.  If the Company shall so determine, new Securities of
          any series, or any Tranche thereof, so modified as to conform, in
          the opinion of the Trustee and the Company, to any such
          supplemental indenture may be prepared and executed by the
          Company and authenticated and delivered by the Trustee in
          exchange for Outstanding Securities of such series or Tranche.

          SECTION 1107.  MODIFICATION WITHOUT SUPPLEMENTAL INDENTURE.

                    To the extent, if any, that the terms of any particular
          series of Securities shall have been established in an Officer's
          Certificate or a Board Resolution as contemplated by Section 301,
          and not in a supplemental indenture, additions to, changes in or
          the elimination of any of such terms may be effected by means of
          a supplemental Officer's Certificate or a supplemental Board
          Resolution, as the case may be, delivered to, and accepted by,
          the Trustee; provided, however, that such supplemental Officer's
          Certificate or supplemental Board Resolution shall not be
          accepted by the Trustee or otherwise be effective unless all
          conditions set forth in this Indenture which would be required to
          be satisfied if such additions, changes or elimination were
          contained in a supplemental indenture shall have been
          appropriately satisfied.  Upon the acceptance thereof by the
          Trustee, any such supplemental Officer's Certificate or
          supplemental Board Resolution shall be deemed to be a
          "supplemental indenture" for purposes of Section 1104 and 1106.


                                    ARTICLE TWELVE

                     MEETINGS OF HOLDERS; ACTION WITHOUT MEETING

          SECTION 1201.  PURPOSES FOR WHICH MEETINGS MAY BE CALLED.

                    A meeting of Holders of Securities of one or more, or
          all, series, or any Tranche or Tranches thereof, may be called at
          any time and from time to time pursuant to this Article to make,
          give or take any request, demand, authorization, direction,
          notice, consent, waiver or other action provided by this
          Indenture to be made, given or taken by Holders of Securities of
          such series or Tranches.

          SECTION 1202.  CALL, NOTICE AND PLACE OF MEETINGS.

                    (a)  The Trustee may at any time call a meeting of
          Holders of Securities of one or more, or all, series, or any
          Tranche or Tranches thereof, for any purpose specified in Section
          1201, to be held at such time and (except as provided in
          subsection (b) of this Section) at such place in the Borough of
          Manhattan, The City of New York, as the Trustee shall determine,
          or, with the approval of the Company, at any other place.  Notice
          of every such meeting, setting forth the time and the place of
          such meeting and in general terms the action proposed to be taken
          at such meeting, shall be given, in the manner provided in
          Section 106, not less than twenty-one (21) nor more than one
          hundred eighty (180) days prior to the date fixed for the
          meeting.

                    (b)  The Trustee may be asked to call a meeting of the
          Holders of Securities of one or more, or all, series, or any
          Tranche or Tranches thereof, by the Company or by the Holders of
          thirty-three percentum (33%) in aggregate principal amount of all
          of such series and Tranches, considered as one class, for any
          purpose specified in Section 1201, by written request setting
          forth in reasonable detail the action proposed to be taken at the
          meeting.  If the Trustee shall have been asked by the Company to
          call such a meeting, the Company shall determine the time and
          place for such meeting and may call such meeting by giving notice
          thereof in the manner provided in subsection (a) of this Section,
          or shall direct the Trustee, in the name and at the expense of
          the Company, to give such notice.  If the Trustee shall have been
          asked to call such a meeting by Holders in accordance with this
          subsection (b), and the Trustee shall not have given the notice
          of such meeting within twenty-one (21) days after receipt of such
          request or shall not thereafter proceed to cause the meeting to
          be held as provided herein, then the Holders of Securities of
          such series and Tranches, in the principal amount above
          specified, may determine the time and the place in the Borough of
          Manhattan, The City of New York, or in such other place as shall
          be determined or approved by the Company, for such meeting and
          may call such meeting for such purposes by giving notice thereof
          as provided in subsection (a) of this Section.

                    (c)  Any meeting of Holders of Securities of one or
          more, or all, series, or any Tranche or Tranches thereof, shall
          be valid without notice if the Holders of all Outstanding
          Securities of such series or Tranches are present in person or by
          proxy and if representatives of the Company and the Trustee are
          present, or if notice is waived in writing before or after the
          meeting by the Holders of all Outstanding Securities of such
          series, or any Tranche or Tranches thereof, or by such of them as
          are not present at the meeting in person or by proxy, and by the
          Company and the Trustee.

          SECTION 1203.  PERSONS ENTITLED TO VOTE AT MEETINGS.

                    To be entitled to vote at any meeting of Holders of
          Securities of one or more, or all, series, or any Tranche or
          Tranches thereof, a Person shall be (a) a Holder of one or more
          Outstanding Securities of such series or Tranches, or (b) a
          Person appointed by an instrument in writing as proxy for a
          Holder or Holders of one or more Outstanding Securities of such
          series or Tranches by such Holder or Holders.  The only Persons
          who shall be entitled to attend any meeting of Holders of
          Securities of any series or Tranche shall be the Persons entitled
          to vote at such meeting and their counsel, any representatives of
          the Trustee and its counsel and any representatives of the
          Company and its counsel.

          SECTION 1204.  QUORUM; ACTION.

                    The Persons entitled to vote a majority in aggregate
          principal amount of the Outstanding Securities of the series and
          Tranches with respect to which a meeting shall have been called
          as hereinbefore provided, considered as one class, shall
          constitute a quorum for a meeting of Holders of Securities of
          such series and Tranches; provided, however, that if any action
          is to be taken at such meeting which this Indenture expressly
          provides may be taken by the Holders of a specified percentage,
          which is less than a majority, in principal amount of the
          Outstanding Securities of such series and Tranches, considered as
          one class, the Persons entitled to vote such specified percentage
          in principal amount of the Outstanding Securities of such series
          and Tranches, considered as one class, shall constitute a quorum. 
          In the absence of a quorum within one hour of the time appointed
          for any such meeting, the meeting shall, if convened at the
          request of Holders of Securities of such series and Tranches, be
          dissolved.  In any other case the meeting may be adjourned for
          such period as may be determined by the chairman of the meeting
          prior to the adjournment of such meeting.  In the absence of a
          quorum at any such adjourned meeting, such adjourned meeting may
          be further adjourned for such period as may be determined by the
          chairman of the meeting prior to the adjournment of such
          adjourned meeting.  Except as provided by Section 1205(e), notice
          of the reconvening of any meeting adjourned for more than thirty
          (30) days shall be given as provided in Section 106 not less than
          ten (10) days prior to the date on which the meeting is scheduled
          to be reconvened.  Notice of the reconvening of an adjourned
          meeting shall state expressly the percentage, as provided above,
          of the principal amount of the Outstanding Securities of such
          series and Tranches which shall constitute a quorum.

                    Except as limited by Section 1102, any resolution
          presented to a meeting or adjourned meeting duly reconvened at
          which a quorum is present as aforesaid may be adopted only by the
          affirmative vote of the Holders of a majority in aggregate
          principal amount of the Outstanding Securities of the series and
          Tranches with respect to which such meeting shall have been
          called, considered as one class; provided, however, that, except
          as so limited, any resolution with respect to any action which
          this Indenture expressly provides may be taken by the Holders of
          a specified percentage, which is less than a majority, in
          principal amount of the Outstanding Securities of such series and
          Tranches, considered as one class, may be adopted at a meeting or
          an adjourned meeting duly reconvened and at which a quorum is
          present as aforesaid by the affirmative vote of the Holders of
          such specified percentage in principal amount of the Outstanding
          Securities of such series and Tranches, considered as one class.

                    Any resolution passed or decision taken at any meeting
          of Holders of Securities duly held in accordance with this
          Section shall be binding on all the Holders of Securities of the
          series and Tranches with respect to which such meeting shall have
          been held, whether or not present or represented at the meeting.

          SECTION 1205.  ATTENDANCE AT MEETINGS; DETERMINATION OF VOTING
                         RIGHTS; CONDUCT AND ADJOURNMENT OF MEETINGS.

                    (a)  Attendance at meetings of Holders of Securities
          may be in person or by proxy; and, to the extent permitted by
          law, any such proxy shall remain in effect and be binding upon
          any future Holder of the Securities with respect to which it was
          given unless and until specifically revoked by the Holder or
          future Holder (except as provided in Section 104(g)) of such
          Securities before being voted.

                    (b)  Notwithstanding any other provisions of this
          Indenture, the Trustee may make such reasonable regulations as it
          may deem advisable for any meeting of Holders of Securities in
          regard to proof of the holding of such Securities and of the
          appointment of proxies and in regard to the appointment and
          duties of inspectors of votes, the submission and examination of
          proxies, certificates and other evidence of the right to vote,
          and such other matters concerning the conduct of the meeting as
          it shall deem appropriate.  Except as otherwise permitted or
          required by any such regulations and approved by the Company, the
          holding of Securities shall be proved in the manner specified in
          Section 104 and the appointment of any proxy shall be proved in
          the manner specified in Section 104.  Such regulations may
          provide that written instruments appointing proxies, regular on
          their face, may be presumed valid and genuine without the proof
          specified in Section 104 or other proof.

                    (c)  The Trustee shall, by an instrument in writing,
          appoint a temporary chairman of the meeting, unless the meeting
          shall have been called by the Company or by Holders as provided
          in Section 1202(b), in which case the Company or the Holders of
          Securities of the series and Tranches calling the meeting, as the
          case may be, shall in like manner appoint a temporary chairman. 
          A permanent chairman and a permanent secretary of the meeting
          shall be elected by vote of the Persons entitled to vote a
          majority in aggregate principal amount of the Outstanding
          Securities of all series and Tranches represented at the meeting,
          considered as one class.

                    (d)  At any meeting each Holder or proxy shall be
          entitled to one vote for each One Thousand Dollars ($1,000)
          principal amount of Outstanding Securities held or represented by
          such Holder; provided, however, that no vote shall be cast or
          counted at any meeting in respect of any Security challenged as
          not Outstanding and ruled by the chairman of the meeting to be
          not Outstanding.  The chairman of the meeting shall have no right
          to vote, except as a Holder of a Security or proxy.

                    (e)  Any meeting duly called pursuant to Section 1202
          at which a quorum is present may be adjourned from time to time
          by Persons entitled to vote a majority in aggregate principal
          amount of the Outstanding Securities of all series and Tranches
          represented at the meeting, considered as one class; and the
          meeting may be held as so adjourned without further notice.

          SECTION 1206.  COUNTING VOTES AND RECORDING ACTION OF MEETINGS.

                    The vote upon any resolution submitted to any meeting
          of Holders shall be by written ballots on which shall be
          subscribed the signatures of the Holders or of their
          representatives by proxy and the principal amounts and serial
          numbers of the Outstanding Securities, of the series and Tranches
          with respect to which the meeting shall have been called, held or
          represented by them.  The permanent chairman of the meeting shall
          appoint two inspectors of votes who shall count all votes cast at
          the meeting for or against any resolution and who shall make and
          file with the secretary of the meeting their verified written
          reports of all votes cast at the meeting.  A record in duplicate
          of the proceedings of each meeting of Holders shall be prepared
          by the secretary of the meeting and there shall be attached to
          such record the original reports of the inspectors of votes on
          any vote by ballot taken thereat and affidavits by one or more
          persons having knowledge of the facts setting forth a copy of the
          notice of the meeting and showing that such notice was given as
          provided in Section 1202 and, if applicable, Section 1204.  Each
          copy shall be signed and verified by the affidavits of the
          permanent chairman and secretary of the meeting and one such copy
          shall be delivered to the Company, and another to the Trustee to
          be preserved by the Trustee, the latter to have attached thereto
          the ballots voted at the meeting.  Any record so signed and
          verified shall be conclusive evidence of the matters therein
          stated.

          SECTION 1207.  ACTION WITHOUT MEETING.

                    In lieu of a vote of Holders at a meeting as
          hereinbefore contemplated in this Article, any request, demand,
          authorization, direction, notice, consent, waiver or other action
          may be made, given or taken by Holders by written instruments as
          provided in Section 104.

                                   ARTICLE THIRTEEN

                  IMMUNITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS
                                    AND DIRECTORS

          SECTION 1301.  LIABILITY SOLELY CORPORATE.

                    No recourse shall be had for the payment of the
          principal of or premium, if any, or interest, if any, on any
          Securities, or any part thereof, or for any claim based thereon
          or otherwise in respect thereof, or of the indebtedness
          represented thereby, or upon any obligation, covenant or
          agreement under this Indenture, against any incorporator,
          stockholder, officer or director, as such, past, present or
          future, of the Company or of any predecessor or successor
          corporation (either directly or through the Company or a
          predecessor or successor corporation), whether by virtue of any
          constitutional provision, statute or rule of law or by the
          enforcement of any assessment or penalty or otherwise; it being
          expressly agreed and understood that this Indenture and all the
          Securities are solely corporate obligations and that no personal
          liability whatsoever shall attach to, or be incurred by, any
          incorporator, stockholder, officer or director, past, present or
          future, of the Company or of any predecessor or successor
          corporation, either directly or indirectly through the Company or
          any predecessor or successor corporation, because of the
          indebtedness hereby authorized or under or by reason of any of
          the obligations, covenants or agreements contained in this
          Indenture or in any of the Securities or to be implied herefrom
          or therefrom; and such personal liability, if any, is hereby
          expressly waived and released as a condition of, and as part of
          the consideration for, the execution and delivery of this
          Indenture and the issuance of the Securities.

                    IN WITNESS WHEREOF, the parties hereto have caused this
          Indenture to be duly executed as of the day and year first above
          written.
