INDEPENDENT ACCOUNTANTS' REPORT

Tucson Electric Power Company
220 West Sixth Street
Tucson, Arizona  85701

We have reviewed the accompanying condensed consolidated balance sheet of Tucson
Electric Power Company and subsidiaries the "Company") as of March 31, 1996 and
the related condensed consolidated statements of income loss) and of cash flows
for the three-month periods ended March 31, 1996 and 1995.  These financial
statements are their responsibility of the Company'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 sheet and statement of capitalization of the
Company as of December 31, 1995 and the related consolidated statements of
income loss), cash flows, and changes in stockholders' equity deficit) for the
year then ended not presented herein); and in our report dated January 29, 1996
which includes an explanatory paragraph relating to the timing of the recovery
of 37.5% of Springerville Unit 2; see   Note 1 to the March 31, 1996 condensed
                                       1
consolidated financial statements for the current status of this matter), we
expressed an unqualified opinion on those consolidated financial statements.  In
our opinion, the information set forth in the accompanying consolidated balance
sheet as of December 31, 1995 is fairly stated, in all material respects, in
relation to the consolidated balance sheet from which is has been derived.

Item 1.  FINANCIAL STATEMENTS

     The March 31 consolidated financial statements are unaudited but reflect
all normal recurring accruals and other adjustments which are, in the opinion
of management, necessary for a fair statement of the results for the interim
periods covered.  Due to seasonal fluctuations in sales, the quarterly
results are not indicative of annual operating results.  Also see Item 2. -

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- -----------------------------------------------------------------------------

NOTE 1.  RATE MATTERS
- ---------------------

     On March 29, 1996, the ACC authorized a 1.1%, or $6.4 million, increase
in base rates effective March 31, 1996.  Pursuant to the 1996 Rate Order, the
Company agreed to not seek an increase in base rates before January 1, 2000,
subject to conditions specified in such order.

     The 1996 Rate Order recognizes all of Springerville Unit 2 as used and
useful for regulatory purposes, so that the Company will be able to recover
operating and capital costs associated with the portion of such generating
unit not previously included in rate base.  Prior to the 1996 Rate Order, the
Company was not recovering through retail rates the depreciation, property
taxes, operating and maintenance expenses other than fuel, or interest costs
associated with the 37.5% of Springerville Unit 2 capacity not deemed by the
ACC to be used and useful for the retail jurisdiction and therefore not
included in rate base (hereinafter referred to as "retail excess capacity
deferrals").  The 1994 Rate Order permitted such costs to be deferred for
future recovery over the remaining useful life of Springerville Unit 2.
However, this phase-in plan did not qualify under FAS 92 and, therefore, such
retail excess capacity deferrals, while deferred for regulatory purposes,
were not deferred for financial reporting purposes and were expensed as
incurred.  Such retail excess capacity deferrals totaled $3 million during
the three months ended March 31, 1996, bringing the total to $81 million at
March 30, 1996.  Beginning March 31, 1996, the total retail excess capacity
deferrals will be amortized for regulatory purposes over 20 years.

     In addition, prior to the 1996 Rate Order, the Company was not
recovering through retail rates 37.5% of the deferred Springerville Unit 2
rate synchronization costs ($28 million at March 30, 1996), which were non-
fuel costs of Springerville Unit 2 incurred from January 1, 1991 through
October 14, 1991.  Beginning March 31, 1996, these costs will be amortized
over a three-year period on the Consolidated Statements of Income (Loss), in
accordance with the 1996 Rate Order.  This amount, together with the balance
of such costs that the Company has been recovering through rates, pursuant to
the 1994 Rate Order, ($11 million at March 31, 1996), are reported in the
Company's Consolidated Balance Sheet as Deferred Springerville Unit 2 Costs.
The amortization of such costs is included in Depreciation and Amortization
on the Company's Consolidated Statements of Income (Loss).

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

     The Arizona Department of Revenue has issued transaction privilege tax
assessments to the Company alleging that Valencia is liable for sales tax on
gross income received from coal sales, transportation and coal-handling
services to the Company for the period November 1985 through May 1993.  The
Company protested the assessments.  On March 11, 1994, the Arizona Tax Court
issued a Minute Entry granting Summary Judgment to the Arizona Department of
Revenue and upholding the validity of the assessment issued for the period
November 1985 through March 1990.  The Company appealed this decision to the
Court of Appeals.  Generally, Arizona law requires payment of the assessment
due prior to the appellate process.  In prior years, the Company has paid,
under protest, a total of $23 million of the disputed sales tax assessments,
subject to refund in the event the Company prevails.

     Also, the Arizona Department of Revenue has issued transaction privilege
tax assessments to the lessors from whom the Company leases certain property.
The assessments allege sales tax liability on a component of rents paid by
the Company on the Springerville Unit 1 Leases, Springerville Common
Facilities Leases, Irvington Lease and Valencia Leases.  Assessments cover
the period August 1, 1988 to September 30, 1993.  Under the terms of the
lease agreements, if the Arizona Department of Revenue prevails the Company
must reimburse the lessors for taxes paid by them pursuant to indemnification
provisions.

     In the opinion of management, the Company has recorded, through the
Consolidated Statements of Income (Loss) in current and prior years, a
liability for the amount of federal and state taxes and interest thereon for
which the Company feels incurrence is probable as of March 31, 1996.  In the
event that all or most of the Arizona Department of Revenue's proposed
assessments are sustained, additional liabilities would result.  Based on the
current status of the legal proceedings, the Company believes that the
ultimate resolution of such disputes will occur over a period of one to four
years.  Although it is reasonably possible that the ultimate resolution of
such matters could result in additional sales tax expense of up to
approximately $27 million in excess of amounts accrued, management and
outside tax counsel believe that the Company has meritorious defenses to
mitigate or eliminate the assessed amounts.  Based on consultations with
counsel, the Company believes that the resolution of the tax matters
described herein should not have a material adverse effect on the Company's
Consolidated Financial Statements.

NOTE 4.  LONG-TERM DEBT
- -----------------------

     On May 1, 1996, the Coconino County, Arizona Pollution Control
Corporation, on behalf of the Company, issued $16.7 million of variable rate
Pollution Control Revenue Bonds.  The Pollution Control Corporation also
issued $14.7 million of variable rate Pollution Control Refunding Revenue
Bonds on behalf of the Company to provide funds to refund previously issued
8.25% Pollution Control Revenue Bonds.  Both issues have a scheduled maturity
in 2031 and are secured by separate Letters of Credit that expire in 1999.

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


     The following contains information regarding  the results of the  Company's
operations during the first quarter of  1996 compared with the first quarter  of
1995, the outlook for  dividends on Common Stock,  and changes in liquidity  and
capital resources  of  the Company  during  the first  quarter  of 1996.    Also
management's expectations of identifiable material trends are discussed.

 OVERVIEW

     Earnings for the  Company improved by  approximately $15.4  million in  the
first quarter  of  1996  relative  to  the same  time  period  in  1995.    This
improvement, from a net  loss of $15.0  million to net  income of $0.4  million,
reflects the recognition  of non-cash tax  benefits of  $9.6 million  associated
with federal net operating loss carryforwards generated in the first quarter  of
1996  and  the  expected  future  utilization  of  federal  net  operating  loss
carryforwards.   See ~Results~of~Utility~Operations,~Income~Taxes~below.    This
improvement also reflects the Company's  continuing efforts to reduce  operating
costs and capital costs, and growth in  the Company's retail service area.   The
Company also ended the first quarter of  1996 with common stock equity of  $12.9
million, compared to a balance of  $12.5 million as of  December 31, 1995 and  a
$57.2 million deficit balance recorded as of March 31, 1995.

     Despite such improvements, the Company's financial prospects continue to be
subject to significant  economic, regulatory  and other  uncertainties, some  of
which are beyond the Company's control.  These uncertainties include the  degree
of utilization of generation capacity through either retail electric service  or
wholesale sales  and the  extent to  which the  Company, due  to continued  high
financial and  operating leverage,  can alter  operations  and reduce  costs  in
response to unanticipated economic downturns or industry changes.  The Company's
                                       7
success will depend, among other things, on the Company's ability to contain the
costs of serving  retail customers  and the level  of sales  to such  customers.
Although the Company anticipates  continued growth in sales  over the next  five
years primarily as a result of anticipated population and economic growth in the
Tucson area, a number of factors such as changes in economic conditions and  the
increasingly competitive electric markets could  affect the Company's levels  of
sales.

     If the Company is unable  to make sales at  prices adequate to recover  its
costs or if for other reasons the Company fails to maintain or improve its  cash
flows, the Company's ability to meet its obligations may be jeopardized.  During
the 1997-2001 period, approximately $1.0 billion of the Company's long-term debt
will  be  maturing,  including  approximately  $805  million  in   reimbursement
agreements relating to letters of credit which will expire.  The Company intends
to pay or refinance maturing bonds and bank loans and to replace or extend  such
letters of credit.  There can be no assurance, however, that the Company will be
able to pay such debt or replace or extend such letters of credit.  In addition,
the Company has a significant amount of variable rate debt and, as a result, the
Company's future cash flows  are also affected by  the level of interest  rates.
See ~Liquidity~and~Capital~Resources~below.

     The Company's  capital  structure is  highly  leveraged and  the  Company's
ability to  raise  capital  through either  public  or  private  financings)  is
limited.  The Company's ability to obtain debt financing is limited by reason of
limited free cash flow available to meet additional interest expense and due  to
the restrictive covenants contained  in existing obligations  to creditors.   To
the extent the Company  refinances its debt obligations  in order to repay  them
when due, such  refinancing may be  made on terms  which may be  adverse to  the
Company.  Such terms  could include, among other  things, higher interest  rates
and various  restrictive  covenants,  such  as  dividend  payment  restrictions.
Access to equity capital may be limited because of the Company's likely  limited

                                       8
future  profitability  and  its  present  inability  to  pay  dividends.     See
~Dividends~on~Common~Stock~~below.

     During the  next twelve  months, the  Company expects  to be  able to  fund
continuing operating activities and construction expenditures with internal cash
flows, existing cash balances, and, if necessary, drawdowns under the  Renewable
Term Loan  and/or  borrowings under  the  Revolving Credit.  Cash  balances  are
invested in  investment  grade,  money-market securities  with  an  emphasis  on
preserving the principal amount invested.

 RATE MATTERS


     On March 27, 1996 the ACC took formal action to resolve the Company's  rate

application which was filed on June 13,  1995.  In that application the  Company
requested an  overall  increase in  retail  rates of  4.9%  approximately  $28.4
million in  annual revenues).   In  its  order dated  March  29, 1996,  the  ACC
approved with certain modifications a rate settlement agreement which was  filed
with the ACC on  March 8, 1996, and  approved a one-time  rate increase for  the
Company of 1.1 percent approximately $6.4 million annually).   The rate increase
was implemented by  the Company on  March 31, 1996  for electrical  usage on  or
after such date.

     The 1996 Rate  Order recognizes  all of Springerville  Unit 2  as used  and
useful for ratemaking purposes so that the  Company will be able to recover  the
operating and capital costs associated with that portion of the generating  unit
not     previously     included      in     rates.           See      ~Note~1~of
the~Notes~to~Consolidated~Financial~Statements~,  ~Rate~Matters.~The  1996  Rate
Order and approved settlement agreement also establish a rate moratorium  period
for the Company.   The  Company has committed not to file  for a change in  base
rates prior to  January 1, 2000,  except for conditions  or circumstances  which
                                       9
constitute an emergency,  for the  sharing of  benefits with  customers of  cost
containment efforts where appropriate, or in  the event the Company is  acquired
or merged with another company.    Among other things,  the 1996 Rate Order  and
approved  settlement  agreement   also  contain  provisions   relating  to   the
implementation of time-of-use rates for residential customers, increased pricing
flexibility for  commercial  and  industrial  customers,  the  consideration  of
incentive regulation and a review  of jurisdictional cost allocation  procedures
for wholesale sales.

     The rates approved in the 1996 Rate Order are based on a rate of return of
6.59 percent on a fair value rate base of approximately $1.36 billion, or 7.72
percent on an original cost rate base of approximately $1.16 billion.  The
capital structure adopted by the ACC for rate making purposes includes 62.5
percent debt and 37.5 percent equity.  Consistent with previous ACC rate orders,
the Company's leasehold interest in utility plant was reflected in rates through
an allowance for rental expense, and was therefore not included in rate base.

 COMPETITION


        WHOLESALE


     The Company competes with other utilities, marketers and independent  power
producers in the sale of electric  capacity and energy in the wholesale  market.
The Company's rates for wholesale sales  of capacity and energy, generally,  are
not permitted to exceed  rates determined on a  cost of service  basis.  In  the
current market,  wholesale prices are substantially below costs determined on  a
fully allocated cost of service basis, but, in all instances, prices exceed  the
level necessary to recover fuel and other  variable costs.  It is expected  that
competition to sell capacity will remain  vigorous, and that prices will  remain
depressed for at least the next several years, due to increased competition  and
                                       10
surplus capacity in the southwestern United States.  Competition for the sale of
capacity and energy is influenced by many factors, including the availability of
capacity in  the southwestern  United States,  the  availability and  prices  of
natural gas and oil, spot energy  prices and transmission access.  In  addition,
the Energy  Act has  promoted increased  competition in  the wholesale  electric
power markets.

     The Energy Policy  Act of  1992 addresses a  wide range  of energy  issues,
including several  matters  affecting bulk  power  competition in  the  electric
utility industry.   It  creates exemptions  from  regulation under  the  Holding
Company Act for persons  or corporations that own  and/or operate in the  United
States certain generating and interconnecting transmission facilities  dedicated
exclusively to wholesale sales, thereby encouraging the participation of utility
affiliates, independent power  producers and other  non-utility participants  in
the development of  power generation.   In  order to  facilitate competition  in
power generation, the Energy  Act also confers expanded  authority upon FERC  to
issue orders requiring electric utilities to transmit power and energy to or for
wholesale purchasers and sellers, and to  require electric utilities to  enlarge
or construct additional transmission capacity to provide these services.

     FERC is encouraging all parties interested  in transmission access to  form
RTGs to facilitate  access to  and development  of transmission  service and  to
assist in settling disputes regarding such matters.  RTGs will not relieve  FERC
of  its  responsibilities   related  to  transmission   access;  however,   such
organizations could provide for more efficient handling of transmission  service
requests and planning for regional transmission needs.  The Company is currently
involved in the development of two RTGs in the  West, SWRTA and WRTA.  WRTA  was
approved by FERC on  May 16, 1995 and  SWRTA was approved  on October 31,  1995.
The Company is a member of SWRTA and is also considering membership in WRTA.  As
a condition of its approval of WRTA and SWRTA as RTGs the FERC has required  all
transmitting utility  members  of  each RTG  to  offer  comparable  transmission
services at least  to other members  of  such  RTG  through  tariffs  that  set
                                       11
forth the rates, terms and conditions of service.

     On March 29, 1995, the FERC issued a Notice of Proposed Rulemaking NOPR) on
Open Access  Non-Discriminatory Transmission  Services by  Public Utilities  and
Transmitting Utilities the Open Access NOPR) and a supplemental NOPR on Recovery
of Stranded Costs the Stranded Costs NOPR).  On December 13, 1995, FERC issued a
third and supplemental NOPR on Real-Time  Information Networks and Standards  of
Conduct.   On  April 24, 1996, the  FERC issued two  orders pertaining to  these
rulemaking proceedings.    Order  Number 888  addresses  both  open  access  and
stranded cost issues.   Order  Number 889  addresses the  issue of  establishing
real-time electronic information systems for transmission capacity, and provides
standards of conduct for owners of transmission capacity.  On this same date the
FERC also issued a NOPR which proposes  to establish a new system for  utilities
to use in reserving capacity on their own and others' transmission lines.

     Pursuant to Order Number 888,   all public utilities that own, control,  or
operate  interstate   transmission  facilities   will  be   required  to   offer
transmission service to others under a  single tariff that incorporates  certain
minimum terms and conditions  of transmission service  established by the  FERC.
This tariff   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.  According to the Order,  the
use of  a single  tariff, when  combined with  other aspects  of the  order,  is
intended  to  promote  wholesale  competition  through  the  provision  of  non-
discriminatory open access  transmission service  by public  utilities.   Public
utilities will be required to file open access tariffs containing the terms  and
conditions outlined in the Order within  60 days after publication of the  final
rules in  the Federal  Register.   With regard  to the  pricing of  transmission
services, the order  does not prescribe  rates for  network, point-to-point,  or
ancillary services.  Instead, public utilities may charge current rates or apply
for new  transmission  rates that  comply  with a  transmission  pricing  policy
statement issued by  the FERC in  1994.  In   establishing   new   rates    for
                                       12
transmission service, the  order allows  transmission providers  to propose  the
recovery of  opportunity costs  and expansion  costs.   Additionally, the  order
permits public utilities  to reserve existing  transmission capacity needed  for
native load  growth  and  network transmission  customer  load  growth  that  is
reasonably forecasted to  occur within the  utility's current planning  horizon.
As proposed in  the new NOPR  pertaining to  transmission capacity  reservation,
each public utility  would be required  to replace the  single pro forma  tariff
established in Order Number 888 with  a capacity reservation tariff by  December
31, 1997.   Comments on this new NOPR are due by August 1, 1996.

     Order Number 888  also provides a  basis for recovery  by regulated  public
utilities of legitimate and verifiable  stranded costs associated with  existing
wholesale requirements  customers  and  retail customers  who  become  unbundled
wholesale transmission  customers  of the  utility.   The  order  allows  public
utilities to seek recovery of wholesale stranded costs from departing customers.
Such recovery would be achieved  through a rate filing  that is premised on  the
direct assignment  of stranded  costs  to the  departing  customer.   The  order
further states that the  FERC would consider allowing  the recovery of  stranded
costs associated  with retail  wheeling only  if a  state regulatory  commission
lacks the authority to consider that issue.

     Order Number 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 that are designed
to prevent employees  of a public  utility engaged in  marketing functions  from
obtaining preferential access to OASIS-related  information or from engaging  in
unduly discriminatory business  practices.  As  such, public  utilities will  be
required to completely separate their wholesale power marketing and transmission
operation functions.  The rules contained in this order will become effective 60
days after publication in the Federal Register.  However, compliance with  these
rules  will  not   be  required   until  November 1, 1996.
                                       13

     The requirements of Order Number 888  and Order Number 889 are still  under
review by the Company.  Therefore, the Company is unable to predict at this time
the  ultimate  impact  of  such  orders  on  the  Company's  future  results  of
operations.

   RETAIL

     Under current law, the Company is not in direct competition with any  other
regulated electric utility for electric service in the Company's retail  service
territory.  Nevertheless, the  Company competes for  retail markets against  gas
service suppliers and  others who  may provide  energy services  which would  be
substitutes for, or bypass of, the Company's services.

     Electric energy for meeting retail customers' needs primarily competes with
natural gas, an alternative  fuel source for certain  retail energy uses.   Such
uses may  include  heating,  cooling  and  a  limited  number  of  other  energy
applications.  In most applications, electric energy is a cost effective  source
of energy compared with natural gas.   Also, customers, particularly  industrial
and large commercial customers, may own and operate facilities to generate their
own  electric  energy  requirements  and,  if  such  facilities  are  qualifying
facilities, to require the displaced electric utility to purchase the output  of
such facilities at "avoided  costs" pursuant to PURPA.   Such facilities may  be
operated by  the customers  themselves or  by other  entities engaged  for  such
purpose.

     The Company actively markets energy and customized energy-related  services
to meet customer  needs. The  Company has  to date  lost no  customers to  self-
generation in  part because  of such  efforts  and in  part because  such  self-
generation alternatives have proven to be uneconomic in comparison with Company-
provided electric  service. For  example, the  Company's two  mining  customers,
which provide approximately 10% of  the  Company's total  annual revenues  from
                                       14
retail customers,  each have  considered  self-generation.   However,  following
negotiations with the Company in 1993 and 1994, new contracts were executed that
included, among  other  things, rate  reductions  and term  extensions.    These
contracts expire after the year 2000, subject to various provisions allowing the
customers to terminate partially or  entirely, under certain circumstances  upon
at least one and up to two years prior notice.  To date, no such notice has been
received.   The  ability to  enter  into or  extend  contracts, to  avoid  early
termination, and to retain customers will  be dependent on, among other  things,
the Company's ability to contain its  costs, market conditions and  alternatives
available to customers from time to time.

     The legislatures and/or the regulatory  commissions in several states  have
considered or are considering "retail wheeling"  which, in general terms,  means
the transmission by  an electric utility  of energy produced  by another  entity
over its  transmission and  distribution system  to a  retail customer  in  such
utility's service  territory.   A requirement  to  transmit directly  to  retail
customers could  have the  result of  permitting  retail customers  to  purchase
electric capacity  and energy  from,  at the  election  of such  customers,  the
electric utility in whose service area  they are located or from other  electric
utilities or independent power  producers.  While  retail wheeling would  expose
the Company's service  territory to increased  competition, it  would also  open
additional markets into which the Company may sell its electric power.

     In Arizona, the  ACC Staff  issued its first  report on  a retail  electric
competition workshop held in  October of 1994.   This report is  the first in  a
series of reports that  will be issued  on various workshops  that will be  held
from time to time to identify and address policy issues related to  competition.
While other  states are  considering competition  proposals, the  ACC effort  is
designed to obtain  information about competition.   No  specific proposals  are
currently  being  considered.    The  report  proposes  that  Staff  develop   a
comprehensive set of options to better inform the ACC about its choices.   Staff
recommended  that   three  options   be  considered:    1)  encouraging  retail
                                       15
competition, 2)  permitting  limited  retail competition,  and  3)  discouraging
retail competition  by  prohibiting  retail wheeling  and  allowing  distributed
energy services.    The ACC  has  also established  a  working group  on  retail
electric competition.   Membership  in the  working  group includes  ACC  Staff,
Arizona utilities, and other  interested parties, and the  first meeting of  the
group took place in January 1995.  A report from the group was issued in October
1995.  This  report concludes  Phase I  of the  Commission's investigation  into
retail electric competition.  In February 1996, Phase II started and is focusing
on obtaining more  information from  interested parties  and recommendations  on
policy.  Responses to a series of questions  posed by the ACC on issues  related
to retail competition and market structure are due  to be filed with the ACC  by
June 28, 1996.  The Company cannot predict what the working group will recommend
and what,  if  any, changes  in  electric  regulation and  competition  will  be
implemented by the ACC.

     The Company continues  to assess  the impact of  the Energy  Act and  other
possible legislation  on the  Company's ability  to  remain competitive  in  the
electric utility industry.  The Company is unable to predict the ultimate impact
the Energy Act or any other possible legislation will have on its operations.

 ACCOUNTING FOR THE EFFECTS OF REGULATION

     The Company  prepares  its  financial statements  in  accordance  with  the
provisions of  FAS 71.   This  statement  requires a  cost-based  rate-regulated
utility  to  reflect  the  effect  of  regulatory  decisions  in  its  financial
statements.  In certain circumstances, FAS 71 requires that certain costs and/or
obligations be reflected in a deferral account  in the balance sheet and not  be
reflected in  the  statement of  income  or  loss until  matching  revenues  are
recognized.  Therefore, the Company's Consolidated  Balance Sheets at March  31,
1996, and at December 31, 1995, contain certain line items for example, Deferred
Debits - Regulatory Assets and MSR Option Gain Regulatory Liability, Accumulated
Deferred   Investment    Tax    Credits  Regulatory   Liability,   and    Other
                                       16
Regulatory Liabilities) solely as  a result of  the application of  FAS 71.   In
addition, a number  of line items  in the Company's  Consolidated Statements  of
Income Loss) for the  quarters ended March  31, 1996 and  1995 also reflect  the
application of FAS 71.

     If at some point in the future the Company determines that all or a portion
of the Company's regulated operations  no longer meet the criteria for continued
application of FAS 71, the Company would be required to adopt the provisions  of
FAS 101 for that portion of the operations  for which FAS 71 no longer  applied.
Adoption of FAS 101 would require the Company to write off its regulatory assets
and liabilities as of  the date of adoption  of FAS 101  and would preclude  the
future deferral in the balance sheet of costs not recovered through rates at the
time such costs were incurred, even if such costs were expected to be  recovered
in the future.   Based on the  balances of the  Company's regulatory assets  and
liabilities as of March 31, 1996, the Company estimates that future adoption  of
FAS 101  for  all of  the  Company's regulated  operations  would result  in  an
extraordinary loss of $142 million, which  includes a reduction for the  related
deferred income taxes of  $68 million.   The Company's cash  flows would not  be
affected by the adoption of FAS 101.

     At the present  time, the Company  recovers the costs  of its plant  assets
through its  regulated revenues.   If  in the  future the  Company  discontinues
accounting according to the provisions of FAS 71, the Company would also need to
consider whether the  markets in which  the Company is  then selling power  will
allow the Company to  recover the costs of  its plant assets.   If at that  time
market prices are not expected to allow the Company to recover the costs of  its
plant assets,  additional write-downs  may be  required in  accordance with  the
provisions of FAS 121.  The Company is presently unable to predict the  amounts,
if any, of any  potential future write-downs attributable  to the provisions  of

 DIVIDENDS ON COMMON STOCK
                                       17

     The  Company  is  precluded  by  restrictive  covenants  in  certain   debt
agreements from declaring or paying dividends.  No dividend on common stock  has
been declared or paid since 1989.

     Under the  applicable  provisions  of amendments  to  the  Arizona  General
Corporation Law, in  effect starting  in 1996, a  company is  permitted to  make
distributions to shareholders unless, after giving effect to such  distribution,
either i) the company would not be able to pay its debts as they come due in the
usual course of business, or ii) the  company's total assets would be less  than
the sum  of its  total liabilities  plus  the amount  necessary to  satisfy  any
liquidation preferences of  shareholders with preferential  rights.  Under  such
provisions, the Company is currently able to declare and pay a dividend.

     The Company's ability to pay a dividend is restricted by certain  covenants
of the General  First Mortgage  applicable so long  as certain  series of  First
Mortgage Bonds aggregating  $184 million in  principal amount) are  outstanding.
These covenants restrict  the payment of  dividends on Common  Stock if  certain
cash flow coverage  and retained  earnings tests  are not  met.   The cash  flow
coverage and  retained  earnings  test will  prevent  the  Company  from  paying
dividends on  its  Common Stock  until  such time  as  the Company's  cash  flow
coverage ratio, as defined therein, is  greater or equal to a  ratio of 2 to  1,
and the  Company  has positive  retained  earnings rather  than  an  accumulated
deficit.  As of March 31,  1996, the Company had a  cash flow coverage ratio  in
excess of 2 to 1 and the Company's  accumulated deficit was $626 million.   Such
covenants will remain in  effect until the First  Mortgage Bonds of such  series
have been paid or redeemed.  The latest maturity of such First Mortgage Bonds is
in 2003.

     The MRA contains  a similar  dividend restriction  based on  the amount  of
retained earnings.  Such  restriction will no longer  apply if i) the  Renewable
Term Loan and the Revolving Credit have  been paid in full and the  commitments
                                       18
relating thereto have  been terminated and  ii) the  Company's senior  long-term
debt is  rated investment  grade.   Currently, the  Company's total  outstanding
amounts under the Renewable  Term Loan are  $31 million and  to date no  amounts
have been borrowed  under the Revolving  Credit.  Commitments  relating to  such
facilities permit the Company  to borrow $133 million  under the Renewable  Term
Loan and $50  million under the  Revolving Credit.   Also, the Company's  senior
debt is currently rated below investment grade.

     In order  for the  Company to  pay  a dividend  when such  covenants  would
otherwise restrict such payment, the Company would have to i) obtain a waiver or
an amendment  to  the  MRA's  retained earnings  covenant  and  ii)  redeem  all
outstanding  First  Mortgage   Bonds  of  the   series  that  contain   dividend
restrictions or amend the General First Mortgage.  Such amendment would  require
approval by holders of 75% of all First Mortgage Bonds.

     In addition  to  such  restrictive  covenants,  the  Company  may  also  be
restricted under the Federal Power Act from paying dividends from funds properly
included in capital account.  The provisions of the Federal Power Act leaves the
scope of any  such restriction and  its potential applicability  to the  Company
unclear.


  EARNINGS


     The Company recorded  net income of  $0.4 million in  the first quarter  of
1996 compared with a  net loss of $15.0  million in the  first quarter of  1995.
The net income per average  share of Common Stock  was essentially zero for  the
first quarter of 1996 compared with a net loss per average share of Common Stock
of $0.09 for the first quarter of 1995.

     KWh sales to  retail customers increased  by 5.9% in  the first quarter  of
1996 compared with the first quarter of  1995 due  to a  3.0% increase  in the
                                       20
average number of retail customers and  an 8.5% increase in sales to  industrial
customers.

     Revenues from sales to retail customers  increased in the first quarter  of
1996 compared with the  same period of  1995 due to  higher kWh sales  discussed
above.

     Higher sales for resale in the first  quarter of 1996 relative to the  same
period in 1995 resulted primarily from  the availability of generating  capacity
which was out of  service in early 1995  due to planned maintenance  activities.
Despite the increase in sales, wholesale revenues declined due to a reduction in
the average  price per  kWh sold.   This  reduction in  the average  unit  price
realized was due primarily to the expiration of a firm power sale agreement with
Nevada Power Company in December 1995.

    OPERATING EXPENSES

     Fuel and Purchased  Power expense increased  in the first  quarter of  1996
compared with the same  period in 1995  primarily as a  result of increased  kWh
sales.  However, fuel  expense increased disproportionately  to the increase  in
revenues due  to  take-or-pay  payments  made in  the  first  quarter  of  1996.
Although the Company's present fuel requirements are generally in excess of  the
stated take-or-pay minimum amounts, from time to time the Company has  purchased
spot market alternative fuels or switched fuel burn from one generating  station
to another in order to achieve  lower overall fuel costs, while incurring  take-
or-pay minimum charges.  As a  result, the Company incurred take-or-pay  minimum
charges of  approximately $1  million during  the first  quarter of  1996.   The
Company incurred no take-or-pay charges in 1995.

     Maintenance and Repairs expense was lower in the first quarter of 1996 than
in the same period of 1995 due primarily  to overhaul work performed at the  San
Juan  and  Springerville  stations   in  early 1995.
                                       21

     Taxes Other  Than Income  Taxes  decreased in  the  first quarter  of  1996
compared with  the same  period in  1995  due to  lower accruals  for  estimated
property taxes.

     Income Taxes benefits)  increased in  the first  quarter of  1996 from  the
first      quarter       of      1995.             See       ~Income~Taxes~below
and~Note~3~of~Notes~to~Financial~Statements,~Income~Taxes~.




    OTHER INCOME

     Income Taxes benefits) included in Other Income also increased in the first
quarter of  1996  from the  first  quarter  of 1995.    See  ~Income~Taxes~below
and~Note~3~of~Notes~to~Financial~Statements,~Income~Taxes~.

     Interest Income  decreased  as  a result  of  lower  short-term  investment
balances and lower interest rates during the first three months of 1996 relative
to the same period  in 1995.   This decrease in  short-term interest income  was
partially offset by the receipt of interest income on approximately $18  million
of Springerville  Unit 1  lease  debt securities  which  were purchased  by  the
Company in May 1995.

     Gains on  Sales  of Securities  decreased  in  the first  quarter  of  1996
relative to the same period in 1995 due  to gains realized in the first  quarter
of 1995 on sales  of certain equity securities  by the investment  subsidiaries.
No such sales occurred in the first quarter of 1996.

     Other income decreased in the first quarter of 1996 compared with the same
period  in   1995  due   primarily   to  expenses     recorded  for   ancillary
                                       22
services provided in the first quarter of 1996.

      INTEREST EXPENSE

     Interest expense on long-term debt decreased  in the first quarter of  1996
relative to the  first quarter of  1995 due to  the retirement of  approximately
$189 million of debt obligations in calendar year 1995 and in the first  quarter
of 1996.

     The  Allowance  for  Borrowed  Funds  Used  During  Construction   interest
deduction) increased in the first quarter of 1996 compared to the same period in
1995 due to a higher balance of construction work-in-progress.

      INCOME TAXES

     Net income tax  benefits increased $12.1  million in the  first quarter  of
1996 from the first quarter of 1995 due primarily to i) a $5 million benefit for
federal net tax operating loss carryforwards NOL) generated in the first quarter
of 1996 and ii) recognition  of a $4.6 million  benefit for the expected  future
utilization of prior period federal NOLs.

     The $5 million benefit relates to  the net operating loss generated in  the
first quarter for tax  purposes.  Each  quarter, the Company  will record, as  a
component of income taxes, an expense or benefit  relating to the quarter's  tax
operating income or loss.  These  quarterly amounts are combined to produce  the
result for the  year.   Due to  seasonal operating  results, the  results for  a
quarter are not indicative of the income tax expense or benefit to be recognized
in subsequent quarters.

     The recognition of the  $4.6 million benefit of  prior period NOLs results
from a revision in the estimated amount of NOLs generated in prior periods  that
the  Company  believes  are  likely  to  reduce taxable income on a future  tax
                                       23
return.   Because  the Company's  results  from operations  have  been  steadily
improving, the three year historical average net book income of the Company  has
increased, and, as a result, the Company now believes it is more likely than not
that it will realize  an additional $13 million  of federal NOLs.   Accordingly,
the Company recognized a $4.6 million income tax benefit related to the expected
utilization of this  $13 million of  federal NOLs.   As of March  31, 1996,  the
Company had recognized a total of $32.6 million of income tax benefits  relating
to federal NOLs. The $32.6 million  consists of $23 million of benefits  related
to prior period  NOLs recognized in  1995, $4.6 million  of benefits related  to
prior period NOLs recognized  in the first  quarter of 1996,  and $5 million  of
benefits related to NOLs generated in the first quarter of 1996.

     Benefits attributable to  state NOLs are  included in Income  Taxes in  the
Consolidated Statement of Income  and are considerably less.   The state  income
tax rate is less than the federal income tax rate and the state NOL carryforward
period is five years as opposed to fifteen years for federal.

     The Company  recognizes benefits  related to  prior  period NOLs  based  on
changes in the estimated amount of NOLs that in the Company's judgment, are more
likely than not  to be  realized in  the future.   A  significant factor,  among
others, considered  in  estimating such  amount  is the  three  year  historical
average net  book  income.   If  the  Company's operating  results  continue  to
improve, the three year  historical average net book  income will increase  and,
correspondingly, the estimated amount of NOLs  that are more likely than not  to
be realized  in the  future will  likely increase.  If the  Company's  operating
results continue to improve, recognition of  prior period federal and state  NOL
benefits totaling approximately $140 million will  likely occur during the  next
three to five years.  The amount, if  any, of NOL benefits recognized in  future
periods may vary significantly from the potential benefits described herein.  In
addition, in future periods when such NOLs are utilized on a tax return,  income
tax expense shown on the Company's Consolidated Statements of Income Loss)  will
not  be   reduced   to   reflect   such  utilization.
                                       24

 LIQUIDITY AND CAPITAL RESOURCES

     The Company expects to generate sufficient  cash flows during 1996 to  fund
its continuing operating activities and construction expenditures.  Furthermore,
the Company believes it  has sufficient cash flow  along with adequate cash  and
temporary investments to  meet expected cash  obligations for  the remainder  of
1996.  However, the Company's projected cash flows are subject to variation  due
to changes in wholesale revenues and  changes in short-term interest rates.   An
increase in short-term interest rates of 100 basis points 1%) would result in an
approximate $10 million increase in annual interest expense.  If cash flows were
to fall short of expectations, the Company would rely on existing cash balances,
borrowings under the Renewable Term Loan and, if necessary, borrowings under the
Revolving Credit.

     At May 9, 1996, the Company had  a loan balance of $31 million  outstanding
under the Renewable Term Loan,  and to date, no  amount has been borrowed  under
the Revolving Credit.   The  Renewable Term  Loan commitment  and the  Revolving
Credit commitment were $164 million and $50 million, respectively.

     The Company's  cash  and  cash  equivalents balance  at  May  9,  1996  was
approximately $46  million.   Cash balances  are  invested in  investment  grade
money-market securities with  an emphasis  on preserving  the principal  amounts
invested.

CASH FLOWS

     The Company's cash and cash equivalents decreased $75 million or 52%,  from
the March 31, 1995 ending balance of $144  million to the March 31, 1996  ending
balance of $69 million.  The reduction was primarily due to debt repayments, the
purchase of debt securities, and investments in energy-related ventures.

                                       25
     Net cash flows from continuing operating activities increased in  aggregate
by $12 million in the first three months  of 1996 compared with the same  period
in 1995.   This increase was due primarily  to a $14.6 million tax payment  made
in the first quarter of  1995 relating to an  appeal of a transaction  privilege
tax                 assessment                  see                  ~Note~2~~of
~Notes~to~Consolidated~Financial~Statements,~Tax~Assessments),~a  reduction   in
interest paid on debt obligations in the  first quarter of 1996 relative to  the
same period  in 1995,  and the  receipt of  cash in  the first  quarter of  1996
related to the sale  of emission allowances.   These contributions to cash  flow
were partially offset by a decrease  in revenues and cash receipts derived  from
wholesale sales of electricity, the receipt of lower interest income, and a 3.6%
increase in wages paid net of amounts capitalized) during the first three months
of 1996 compared with the same period in 1995.

     Net cash  flows from  investing activities  decreased in  aggregate  by $6
million in the first three months of 1996 compared with the same period in 1995.
This decrease in net cash flow was due to increased construction expenditures in
the first quarter of 1996, as well as to  the receipt of proceeds from sales  of
investment subsidiary securities in the first quarter of 1995.

     Net cash outflows from financing activities  were $82 million lower in  the
first three months of 1996 compared with the same period in 1995 as a result  of
lower debt principal repayments.

FINANCING DEVELOPMENTS

     On February 1,  1996, the  Company retired  upon maturity  the $10  million
balance of 4.875% first mortgage bonds then outstanding.

     On May  1, 1996,  the Pollution  Control  Corporation of  Coconino  County,
Arizona issued  $16.7  million  aggregate  principal  amount  of  its  Series  A
pollution control revenue bonds for the  benefit of the Company.  The  proceeds
                                       26
from this issuance have been loaned to the Company to reimburse the Company  for
expenditures related to the Company's interest in pollution abatement facilities
at the Navajo Generating Station.

     On May  1, 1996,  the Pollution  Control  Corporation of  Coconino  County,
Arizona also issued $14.7 million aggregate principal of its Series B  pollution
control refunding revenue bonds  for the benefit of  the Company.  The  proceeds
from this issuance have been loaned to the Company and will be used on June  14,
1996, to redeem  all of the  Company's 1975 Series  A pollution control  revenue
bonds 8.25% due  in 2005) currently outstanding.

     Interest rates on the newly issued bonds will initially be reset weekly  by
the remarketing agent.  The initial rates of interest on the bonds, expressed on
an annual basis, were 4.25% for the 1996 Series  A bonds and 4.15% for the  1996
Series B bonds.   Pursuant to  the terms of  the offering, the  Company has  the
right, subject to certain conditions, to change the variable interest rate  term
or to convert  the interest rate  from a variable  rate to a  fixed rate.   Both
issues have a stated maturity date  of May 1, 2031,  and are backed by  separate
irrevocable letters of credit which terminate in 1999 .

and the sole right under this Agreement to supervise and control,
directly  or indirectly, all aspects of the construction  of  the

a revised Exhibit A containing a description of the Facilities as
revised,  the accuracy of which shall have been certified  by  an
Authorized  Company Representative, and (b) an  opinion  of  Bond

exclusion from gross income for federal tax purposes of  interest
on  the  Bonds.  A revision of Exhibit A hereto pursuant to  this

all  needful and proper repairs and renewals thereto to be  made;
provided,  however,  that the Company may  exercise  all  of  its
rights,  powers, elections and options under the Plant Agreements
to  cause the operation of the Facilities, or any element or unit

Facilities, by means of an adequate insurance fund set aside  and
maintained  by it out of its own earnings or in conjunction  with
other  companies  through  an  insurance  fund,  trust  or  other
agreement  or,  by  means of unfunded self-insurance  as  may  be
reasonable  and  customary  by  companies  owning  and  operating
similar  property.  All proceeds of such insurance shall  be  for
the account of the Company.

  2.010       Condemnation.  The Company shall be entitled to the
entire proceeds of any condemnation award or portion thereof made
for damages to or takings of the Facilities or other property  of
the Company.

Agreement to the contrary notwithstanding, the Company shall have
the  right  at  any time to exercise all of its  rights,  powers,
elections and options under the Plant Agreements to terminate the
construction  of the Facilities, in whole, if the  Company  shall
have  determined that the continued construction or operation  of
the  Facilities,  in  whole,  is impracticable,  uneconomical  or
undesirable for any reason.

  (a)    Promptly after the termination of the construction of the
Facilities,  the  Company shall submit to the  Pollution  Control
Corporation  and  the  Trustee  a  certificate,  executed  by  an
Authorized Company Representative, which shall state the  reasons
for   such  termination  and  shall  state  that  the   Cost   of
Construction, to the extent of the construction of the Facilities
as of the date of such termination, has been paid, except for any
Costs  of Construction which have been incurred but are not  then
due  and  payable, or the liability for the payment of  which  is
being  contested or disputed by the Company, and for the  payment
of  which the Trustee is directed to retain specified amounts  of
moneys  in  specified  accounts  within  the  Construction  Fund.
Notwithstanding the foregoing, such certificate may state that it
is  given  without prejudice to any rights against third  parties
which  exist  at the date thereof or which may subsequently  come
into being.

Pollution  Control  Corporation of all covenants  and  conditions
expressed herein and in the Indenture and contained in the Bonds,
the  Company  hereby  mortgages, pledges,  assigns,  creates  and
grants  a  security interest in and confirms to the Trustee  such
right, title and interest as the Company may be deemed to have or
hereafter acquire in the proceeds of the issuance and sale of the
Bonds to be deposited into the Construction Fund and the proceeds
from  the  investment and reinvestment thereof,  upon  terms  and
conditions  co-extensive with those set forth  in  the  Indenture
with respect to the lien and security interest of the Trustee  in
the Trust Estate (as defined in the Indenture).

  2.015       Disbursements from Construction Fund.  (a)  To  the
extent that moneys on deposit in the Construction Fund shall  not
otherwise have been applied in accordance with the provisions  of
Article  V of the Indenture, such moneys shall be loaned  to  the
Company  from time to time to reimburse the Company for  portions
of  the  Cost  of Construction paid by it or to make payments  to
persons designated by the Company in respect of portions  of  the
Cost of Construction, upon receipt by the Trustee of requisitions
executed  by,  or communications by telegram, telex or  facsimile
transmission  from,  an Authorized Company Representative,  which
requisitions or communications shall state with respect  to  each
payment to be made: (i) the requisition number, (ii) the name and
address of the person, firm or corporation to whom payment is due
or  has been made (or, in the case of payments to the Bond  Fund,
instructions  to  make such payments thereto), (iii)  the  amount
paid  or  to  be  paid, (iv) the account or accounts  within  the
Construction Fund from which payment of such requisition, or  any
portion  thereof,  shall be made, (v) (A) that  each  obligation,
item of cost or expense with respect to which such requisition is
being  made  has been properly incurred and has been paid  or  is
then due and payable as an item of the Cost of Construction, is a
proper charge against the Construction Fund, and has not been the
basis  of  any  previous  final payment  therefrom  or  from  the
proceeds of any other obligations issued by the Pollution Control
Corporation or (B) in the event that a portion of the Bonds shall
have  been paid, redeemed or deemed to have been paid within  the
meaning  of  Article  VIII  of the Indenture  by  reason  of  the
application of the proceeds of the sale of any obligations issued
under an indenture other than the Indenture and if the payment of
such requisition is to be made into the construction, acquisition
or  other  similar fund created under such other indenture,  that
upon  disbursement from such construction, acquisition  or  other
similar  fund, each obligation, item of cost or expense mentioned
in  the requisition for such disbursement will have been properly
incurred and will have been paid or will then be due and  payable
as  an  item of the Cost of Construction, will be a proper charge
against the construction, acquisition or other similar fund under
such  indenture, and will not have been the basis of any previous
final payment therefrom or from the proceeds of any other revenue
bonds issued by the Pollution Control Corporation, (vi) that  the
payment of such requisition will not result in a breach of any of
the  covenants of the Company contained in subsection (c) or  (d)
of this Section 4.04 and (vii) that, to the best of the knowledge
of  such Authorized Company Representative, there shall not  have
occurred  and  be  continuing any Event of Default  described  in
Section  8.01 hereof.  Any such communication by telegram,  telex
or  facsimile  transmission  shall be  promptly  confirmed  by  a
requisition  executed  by  an Authorized Company  Representative.
The Company shall furnish to the Pollution Control Corporation  a
copy  of each requisition delivered to the Trustee promptly  upon
request therefor.

  (a)     In paying any requisition under this Section 4.04,  the
Trustee  shall  be  entitled  to  conclusively  rely  as  to  the
completeness  and accuracy of all statements in such  requisition
upon  the  approval of such requisition by an Authorized  Company
Representative,  execution thereof to be conclusive  evidence  of
such  approval, and the Company shall indemnify and save harmless
the  Pollution  Control  Corporation and  the  Trustee  from  any
liability incurred in connection with any requisition so executed
by an Authorized Company Representative.

  (b)     The Company shall not submit requisitions for Costs  of
Construction  which, on a cumulative aggregate  basis,  if  paid,
would  result in less than 97% of the sum of the total amount  of
the  proceeds of the Bonds expended, for any purpose, being  used
to  provide  air  or water pollution control or sewage  or  solid
waste  disposal facilities or other exempt facilities,  including
facilities  functionally related or subordinate  thereto,  within
the  meaning  of Section 141 of the Code or Section 103(b)(4)  of
the  1954 Code, as applicable; provided, however, that the moneys
paid  from  the  Investment Account within the Construction  Fund
shall  be disregarded for purposes of the foregoing covenant  and
all  computations  made in accordance therewith  if  the  Company
shall have furnished to the Pollution Control Corporation and the
Trustee an opinion of Bond Counsel to the effect that such moneys
may  be so disregarded without impairing the exclusion from gross
income for federal tax purposes of interest on the Bonds.

     (c)    The Company shall not submit or cause to be submitted to
the  Trustee any requisition pursuant to this Section  4.04,  and
shall have no claim upon any moneys in the Construction Fund,  so
long as there shall have occurred and be continuing any Event  of
Default described in Section 8.01 hereof.


                           ARTICLE V

                LOAN PAYMENTS; OTHER OBLIGATIONS

  2.016       Loan Payments.  In consideration of the issuance of
the  Bonds  and  the  disposition  of  the  proceeds  thereof  as
contemplated  in Section 4.03 hereof, the Company shall  pay,  or
cause to be paid, to the Trustee for the account of the Pollution
Control  Corporation  an amount equal to the aggregate  principal
amount  of  the  Bonds  from  time to time  Outstanding  and,  as
interest on its obligation to pay such amount, an amount equal to
premium, if any, and interest on such Bonds, such amounts  to  be
paid in installments due on the dates, in the amounts and in  the
manner  provided  in  the  Indenture for  the  Pollution  Control
Corporation to cause amounts to be deposited in the Bond Fund for
the payment of the principal of and premium, if any, and interest
on  the  Bonds  whether at stated maturity,  upon  redemption  or
acceleration or otherwise; provided, however, that the obligation
of  the  Company  to  make any such payment  hereunder  shall  be
reduced by the amount of any reduction under the Indenture of the
amount  of the corresponding payment required to be made  by  the
Pollution Control Corporation thereunder; and provided,  further,
that  the obligation of the Company to make any payment hereunder
shall  be deemed to be satisfied and discharged to the extent  of
the  corresponding payment made to the Trustee under any Security
Arrangement.

  2.017        Payments  Assigned; Obligation  Absolute.   It  is
understood  and  agreed  that  all  Loan  Payments  are,  by  the
Indenture, to be pledged by the Pollution Control Corporation  to
the  Trustee,  and that all rights and interest of the  Pollution
Control  Corporation hereunder (except for the Pollution  Control
Corporation's  rights under Sections 5.03, 5.04,  6.03  and  8.05
hereof  and  any  rights of the Pollution Control Corporation  to
receive  notices, certificates, requests, requisitions and  other
communications hereunder), including any right to delivery of any
Security  Arrangement,  are to be pledged  and  assigned  to  the
Trustee.   The Company assents to such pledge and assignment  and
agrees  that  the  obligation of the Company  to  make  the  Loan
Payments and to make, or cause to be made, payments under Section
10.01(a)  hereof shall be absolute, irrevocable and unconditional
and  shall  not  be  subject  to  cancellation,  termination   or
abatement, or to any defense other than payment or to  any  right
of  set-off, counterclaim or recoupment arising out of any breach
by  the Pollution Control Corporation or the Trustee or any other
party under this Agreement, the Indenture or otherwise, or out of
any  obligation or liability at any time owing to the Company  by
the  Pollution  Control Corporation, the  Trustee  or  any  other
party,  and,  further,  that  the Loan  Payments  and  the  other
payments due hereunder shall continue to be payable at the  times
and  in the amounts herein and therein specified, whether or  not
the Facilities, or any portion thereof, shall have been completed
or  shall have been destroyed by fire or other casualty, or title
thereto,  or  the  use  thereof, shall have  been  taken  by  the
exercise of the power of eminent domain, and that there shall  be
no  abatement  of  or diminution in any such payments  by  reason
thereof,  whether or not the Facilities shall be used or  useful,
whether  or  not  any applicable laws, regulations  or  standards
shall  prevent or prohibit the use of the Facilities, or for  any
other reason, all of the foregoing being subject, however, to the
provisions of Sections 6.01 and 7.01 hereof.

  2.018       Payment of Expenses.  The Company shall pay, or, to
the  extent permitted by this Agreement, cause to be paid out  of
the   Construction  Fund,  all  Administration  Expenses  of  the
Pollution  Control  Corporation, including,  without  limitation,
Administration Expenses incurred at and subsequent  to  the  time
the Bonds are deemed to have been paid in accordance with Article
VIII  of the Indenture.  The payment of the compensation and  the
reimbursement  of expenses and advances of the  Trustee,  of  the
paying  agent,  any co-paying agent and the registrar  under  the
Indenture and of the Tender Agent and the Remarketing Agent shall
be made directly to such entities.

  2.019       Indemnification.  The Company releases the Pollution
Control  Corporation,  the  Trustee, the  Tender  Agent  and  the
Remarketing  Agent and their directors, officers,  employees  and
agents  from, agrees that the Pollution Control Corporation,  the
Trustee, the Tender Agent and the Remarketing Agent shall not  be
liable  for,  and  agrees  to indemnify and  hold  the  Pollution
Control  Corporation, the Trustee, any predecessor  Trustee,  the
Tender  Agent  and  the  Remarketing Agent and  their  directors,
officers,  employees  and  agents free  and  harmless  from,  any
liability for any loss or damage to property or any injury to  or
death  of  any person (including, without limitation,  attorneys'
and  other  agents' fees and expenses) that may be occasioned  by
any  cause whatsoever pertaining to the Facilities, except in any
case  as  a  result  of the negligence or bad  faith  or  willful
misconduct of the party otherwise to be indemnified.

   The  Company  will  indemnify and hold the  Pollution  Control
Corporation,  the  Trustee, any predecessor Trustee,  the  Tender
Agent  and the Remarketing Agent free and harmless from any loss,
claim,  damage, tax, penalty, liability, disbursement, litigation
expenses, attorneys' and other agents' fees and expenses or court
costs arising out of, or in any way relating to, the execution or
performance of this Agreement, the issuance or sale of the Bonds,
actions  taken under the Indenture or any other cause  whatsoever
pertaining to the Facilities, except in any case as a  result  of
the  negligence or bad faith or willful misconduct of  the  party
otherwise to be indemnified.

   The  Company  will  indemnify and hold the  Pollution  Control
Corporation  and  its directors, officers, employees  and  agents
free  and  harmless from any loss, claim, damage,  tax,  penalty,
liability, disbursement, litigation expenses, attorney's fees and
expenses or court costs arising out of or in any way relating  to
any untrue statements or alleged untrue statement of any material
fact  or  omission or alleged omission to state a  material  fact
necessary  to  make  the  statements  made,  in  light   of   the
circumstances under which they were made, not misleading  in  any
official  statement  or  other  offering  material  utilized   in
connection with the sale of any Bonds.

  2.020        Payment of Taxes; Discharge of Liens.  The Company
shall:  (a)  pay, or make provision for payment  of,  all  lawful
taxes  and  assessments, including income, profits,  property  or
excise taxes, if any, or other municipal or governmental charges,
levied  or assessed by any federal, state or municipal government
or political body upon the Facilities or any part thereof or upon
the  Pollution  Control  Corporation with  respect  to  the  Loan
Payments  or  payments pursuant to Section 10.01(a) hereof,  when
the  same  shall become due; and (b) pay or cause to be satisfied
and   discharged  or  make  adequate  provision  to  satisfy  and
discharge,  within sixty (60) days after the same  shall  accrue,
any lien or charge upon the Loan Payments or payments pursuant to
Section  10.01(a) hereof, and all lawful claims  or  demands  for
labor,  materials,  supplies or other charges which,  if  unpaid,
might  be or become a lien upon such amounts; provided, that,  if
the  Company shall first notify the Pollution Control Corporation
and  the  Trustee of its intention so to do, the Company  may  in
good  faith contest any such lien or charge or claims or  demands
in  appropriate legal proceedings, and in such event  may  permit
the  items so contested and identified as such by the Company  to
remain  undischarged and unsatisfied during the  period  of  such
contest and any appeal therefrom, unless the Trustee shall notify
the  Company  in writing that, in the opinion of counsel  to  the
Trustee  based  upon  material facts  disclosed  to  the  Trustee
without  any  duty of investigation, by nonpayment  of  any  such
items  the lien of the Indenture as to the Loan Payments will  be
materially endangered, in which event the Company shall  promptly
pay  and  cause  to be satisfied and discharged all  such  unpaid
items.   The Pollution Control Corporation shall cooperate  fully
with the Company in any such contest.


                           ARTICLE VI

                       SPECIAL COVENANTS

  2.021        Maintenance  of  Corporate Existence.   Except  as
permitted  in  this Section 6.01, the Company shall maintain  its
corporate  existence, will not dissolve or otherwise  dispose  of
all  or  substantially all of its assets and will not consolidate
with or merge with or into another corporation.  The Company  may
consolidate  with or merge into another corporation  incorporated
under the laws of the United States of America, any state thereof
or  the  District  of  Columbia, or sell, transfer  or  otherwise
dispose  of  all  or  substantially all of its  assets  (and  may
thereafter dissolve) to any Person if the surviving or  resulting
corporation (if other than the Company) or the transferee Person,
as  the case may be, prior to or simultaneously with such merger,
consolidation,  sale,  transfer  or  disposition,   assumes,   by
delivery to the Trustee and the Pollution Control Corporation  of
an instrument in writing satisfactory in form to the Trustee, all
the  obligations  of  the  Company  hereunder  including  without
limitation the obligations of the Company under Sections 5.01 and
10.01(a) hereof.  Notwithstanding the foregoing, in the  case  of
any  such  sale, transfer or other disposition by the Company  of
all  or  substantially  all of its assets,  (x)  any  such  sale,
transfer  or  other  disposition of  assets  which  includes  the
Facilities  shall be subject to the provisions  of  Section  7.01
hereof and shall not be subject to the provisions of this Section
6.01  and  (y)  in the case of any such sale, transfer  or  other
disposition of substantially all of the Company's assets but  not
including the Facilities, the transferee shall not be required to
assume  any  obligations hereunder and the Company  shall  remain
liable in respect of its obligations hereunder.

   If consolidation, merger or sale or other transfer is made  as
permitted  by  this Section 6.01, the provisions of this  Section
6.01  shall  continue  in full force and effect  and  no  further
consolidation,  merger or sale or other transfer  shall  be  made
except in compliance with the provisions of this Section 6.01.

  2.022        Permits or Licenses.  In the event that it may  be
necessary  for  the proper performance of this Agreement  on  the
part of the Company or the Pollution Control Corporation that any
application or applications for any permit or license to do or to
perform  certain  things  be made to any  governmental  or  other
agency  by the Company or the Pollution Control Corporation,  the
Company  and  the Pollution Control Corporation each shall,  upon
the request of either, execute such application or applications.

  2.023       Pollution Control Corporation's Access to Facilities.
The  Pollution  Control Corporation shall have  the  right,  upon
appropriate  prior  notice  to the Company,  to  have  reasonable
access  to  the Facilities during normal business hours  for  the
purpose of making examinations and inspections of the same.

  2.024       Tax-Exempt Status of Interest on Bonds. (a)  It  is
the  intention of the parties hereto that interest on  the  Bonds
shall be and remain tax-exempt, and to that end the covenants and
agreements  of the Pollution Control Corporation and the  Company
in this Section 6.04 and the Tax Agreement are for the benefit of
the Owners from time to time of the Bonds.

       (b)   Each  of  the  Company  and  the  Pollution  Control
Corporation  covenants and agrees for the benefit of  the  Owners
from  time  to  time of the Bonds that it will  not  directly  or
indirectly  use  or permit the use of (to the extent  within  its
control) the proceeds of any of the Bonds or any other funds,  or
take  or omit to take any action, if and to the extent such  use,
or the taking or omission to take such action, would cause any of
the  Bonds to be "arbitrage bonds" within the meaning of  Section
148  of  the Code or otherwise subject to federal income taxation
by  reason  of  Section 103 and 141 through 150 of  the  Code  or
Section 103 of the 1954 Code and Title XIII of the Tax Reform Act
of   1986,   as   applicable,  and  any  applicable   regulations
promulgated  thereunder.   To such ends,  the  Pollution  Control
Corporation and the Company will comply with all requirements  of
such  Section 148 to the extent applicable to the Bonds.  In  the
event  that at any time the Pollution Control Corporation or  the
Company  is  of  the opinion that for purposes  of  this  Section
6.04(b)  it  is necessary to restrict or limit the yield  on  the
investment of any moneys held by the Trustee under the Indenture,
the  Pollution Control Corporation or the Company shall so notify
the Trustee in writing.

      Without  limiting  the  generality of  the  foregoing,  the
Company  and the Pollution Control Corporation agree  that  there
shall  be  paid  from  time to time all amounts  required  to  be
rebated  to  the  United States of America  pursuant  to  Section
148(f) of the Code and any applicable Treasury Regulations.  This
covenant shall survive payment in full or defeasance of the Bonds
and the satisfaction and discharge of the Indenture.  The Company
specifically  covenants to pay or cause to be  paid  for  and  on
behalf  of the Pollution Control Corporation to the United States
of  America  at  the  times and in the amounts  determined  under
Section 7.08 of the Indenture the Rebate Requirement as described
in the Tax Agreement.

       (c)   The  Pollution  Control  Corporation  certifies  and
represents  that  it  has not taken, and  the  Pollution  Control
Corporation  covenants  and agrees that it  will  not  take,  any
action which results in interest paid on the Bonds being included
in  gross  income  of  the Owners of the Bonds  for  federal  tax
purposes  pursuant  to Sections 103 and 141 of  the  Code  or  to
Section 103 of the 1954 Code and Title XIII of the Tax Reform Act
of  1986, as applicable, and any regulations thereunder; and  the
Company certifies and represents that it has not taken or (to the
extent within its control) permitted to be taken, and the Company
covenants  and  agrees that it will not take or  (to  the  extent
within  its  control) permit to be taken any  action  which  will
cause  the  interest on the Bonds to become includable  in  gross
income  for federal income tax purposes; provided, however,  that
neither  the Company nor the Pollution Control Corporation  shall
be deemed to have violated these covenants if the interest on any
of  the  Bonds  becomes taxable to a person solely  because  such
person  is  a  "substantial user" of the Project  or  a  "related
person"  within  the meaning of Section 103(b)(13)  of  the  1954
Code;  and  provided,  further, that none of  the  covenants  and
agreements  herein contained shall require either the Company  or
the  Pollution  Control  Corporation to enter  an  appearance  or
intervene   in  any  administrative,  legislative   or   judicial
proceeding  in  connection with any changes in  applicable  laws,
rules  or regulations or in connection with any decisions of  any
court  or  administrative  agency  or  other  governmental   body
affecting  the  taxation of interest on the Bonds.   The  Company
acknowledges having read Section 7.08 of the Indenture and agrees
to perform all duties imposed on it by such Section 7.08, by this
Section and by the Tax Agreement.  Insofar as Section 7.08 of the
Indenture    and   the   Tax   Agreement   impose   duties    and
responsibilities   on   the  Company,   they   are   specifically
incorporated herein by reference.

      (d)  Notwithstanding any provision of this Section 6.04 and
Section  7.08 of the Indenture, if the Company shall  provide  to
the  Pollution Control Corporation and the Trustee an opinion  of
Bond  Counsel  to  the effect that any specified action  required
under  this Section 6.04 and Section 7.08 of the Indenture is  no
longer  required  or  that some further or  different  action  is
required  to  maintain the tax-exempt status of interest  on  the
Bonds,  the  Company,  the  Trustee  and  the  Pollution  Control
Corporation may conclusively rely upon such opinion in  complying
with  the  requirements of this Section 6.04, and  the  covenants
hereunder shall be deemed to be modified to that extent.

  2.025        Use of Facilities.  So long as the Facilities  are
operated by or for the benefit of the Company, the Company  shall
exercise  all of its rights, powers, elections and options  under
the  Plant  Agreements to cause the Facilities  to  be  used  for
purposes contemplated by the Act.

  2.026        Financing Statements.  The Company shall file  and
record,  or  cause  to  be  filed  and  recorded,  all  financing
statements  and continuation statements referred  to  in  Section
7.07 of the Indenture.

  2.027        Security Arrangements.  (a)  In order  to  secure,
evidence or be otherwise in furtherance of the obligations of the
Company  under Section 5.01 or 10.01 hereof, or both, the Company
may,  but (except as otherwise provided in subsection (b) of this
Section 6.07) shall not be obligated to, provide, subject to  the
provisions  of subsection (g) of this Section 6.07, one  or  more
Security  Arrangements (which shall not have a stated  Expiration
Date  earlier than the earlier of (x) the date which is one  year
from  the  date of the provision of any such Security Arrangement
and  (y)  [final maturity date]) at any time, and  from  time  to
time,  and, subject to the provisions of subsections (c) and  (d)
of  this  Section 6.07, may, at any time and from time  to  time,
Terminate, or cause or allow to be terminated, any such  Security
Arrangement.   The  Company  hereby authorizes  and  directs  the
Trustee  to draw moneys under the Letter of Credit, and  to  take
actions under any other Security Arrangement, in accordance  with
the terms thereof and of the Indenture.

  (a)    Upon the initial authentication and delivery of the Bonds,
the  Company  shall  provide for the payment of  its  obligations
under  Sections  5.01  and 10.01 hereof by the  delivery  of  the
Letter of Credit.

  The Letter of Credit shall be the obligation of the Bank to pay
to  the  Trustee  or its designee, in accordance with  the  terms
thereof, such amounts as shall be specified therein and available
to be drawn thereunder for the timely payment of the principal of
and  premium, if any, and interest on the Bonds, and the purchase
price  of  Bonds,  required  to  be  made  pursuant  to,  and  in
accordance with, the provisions of the Indenture.  Drawings under
the  Letter  of  Credit  shall be made  in  accordance  with  the
provisions set forth therein and in the Indenture.

   The Company may, at its election, and with the consent of  the
Bank,  provide for one or more extensions of the Letter of Credit
in accordance with the terms of the Reimbursement Agreement.

  (b)     In  the event that the Company shall cause or  allow  a
Security  Arrangement to be Terminated, not more than sixty  (60)
days nor less than twenty (20) days prior to the Interest Payment
Date  next  preceding, or, while the Bonds  bear  interest  at  a
Flexible  Rate,  prior  to  the latest  then  scheduled  Interest
Payment  Date for any Bond, the proposed effective date  of  such
Termination:

     (i)   the  Company  shall deliver to the  Pollution  Control
  Corporation,  the  Trustee, the Tender Agent,  the  Remarketing
  Agent  and  the  Bank a notice which (A) states  the  effective
  date  of such Termination (which date shall not be earlier than
  the  first Business Day after such Interest Payment Date),  (B)
  describes any substitute Security Arrangement which  is  to  be
  provided  in  lieu thereof and (C) directs the  Trustee,  after
  taking  such actions thereunder as are required to be taken  to
  provide moneys due under the Indenture in respect of the  Bonds
  or  the  purchase  thereof, to surrender any  evidence  of  the
  Security  Arrangement to be Terminated to the  obligor  thereon
  on  the  effective date of such Termination, and  to  thereupon
  deliver  any  and  all instruments to effect  such  Termination
  which may be reasonably requested by such obligor; and

     (ii)   the  Company  shall furnish to the  Trustee  and  the
  Tender Agent an opinion of Bond Counsel to the effect that  the
  Termination of such Security Arrangement and the provision,  if
  any,  of a substitute Security Arrangement in lieu thereof  (A)
  are  authorized  under this Agreement and (B) will  not  impair
  the  validity  under the Act of the Bonds or the  exclusion  of
  interest on the Bonds from gross income for federal income  tax
  purposes.

  (c)    The Interest Payment Date next preceding the date of any
such  Termination shall not be prior to the first date  on  which
the  Bonds  are  redeemable  at  a  redemption  price  (including
premium,  if any) not exceeding the amount available to be  drawn
under  the  Security  Arrangement in respect of  such  redemption
price  pursuant  to Section 3.01(c) of the Indenture  unless  the
Company shall have furnished to the Trustee, the Tender Agent and
the  Remarketing  Agent, no later than the  fortieth  (40th)  day
preceding  such Interest Payment Date, and prior  to  taking  any
action  under such Security Arrangement to effect the Termination
thereof,  letters  or  certificates to the  effect  specified  in
Section 2.02(h)(iii) of the Indenture.

   Anything  in  this Agreement or the Indenture to the  contrary
notwithstanding, (i) if a substitute Security Arrangement  is  to
be  provided,  the substitute Security Arrangement  shall  become
effective on or before the Termination date of the then  existing
Security Arrangement and (ii) in the event that a Termination  of
a   Security  Arrangement,  or  the  Termination  of  a  Security
Arrangement and the provision of another Security Arrangement  in
lieu  thereof,  shall  require  the  Bonds  to  be  tendered  for
purchase, the Termination of such Security Arrangement shall  not
occur  until the Trustee or its duly authorized agent shall  have
made  such drawings, if any, or taken such other actions, if any,
thereunder as shall be required under the Indenture in  order  to
provide  sufficient moneys for payment of the purchase  price  of
Bonds  on  the date fixed for such mandatory tender for  purchase
and  such moneys shall have been provided to the Trustee  or  its
duly authorized agent.

  (d)       The  Company  shall, prior to the  provision  of  any
Security  Arrangement (other than the initial Letter of  Credit),
deliver  to the Trustee, the Tender Agent, the Remarketing  Agent
and  the  Bank a notice which describes any Security  Arrangement
which  is  to be provided and states the effective date  thereof,
and  shall, concurrently with the giving of such notice,  furnish
to  the Trustee an opinion of Bond Counsel to the same effect  as

  (e)     The  Company shall Terminate, or cause or allow  to  be
Terminated, any Security Arrangement on the first day of  a  Term
Rate Period or the Fixed Rate Period if such Security Arrangement
will  Expire prior to the first date on which the Bonds  will  be
redeemable  pursuant to Section 3.01(c) of  the  Indenture  at  a
redemption  price (including premium, if any) not  exceeding  the
amount available to be drawn under such Security Arrangement.

  (f)    The Company shall not, on or after the fortieth (40th) day
preceding  the first day of a Term Rate Period or the Fixed  Rate
Period, provide a Security Arrangement which will Expire prior to

affiliate of the Company or the Pollution Control Corporation  or
any  "insider" of either thereof within the meaning of the United
States  Bankruptcy Code, 11 U.S.C. Section 101 et seq., if  there
shall  be  in effect a security arrangement on which the  Company
shall not be the Obligor.


                          ARTICLE VII

                ASSIGNMENT, LEASING AND SELLING

  2.028       Conditions.  The Company's interest in this Agreement
may  be  assigned as a whole or in part, and its interest in  the
Facilities may be leased, sold, transferred or otherwise disposed
of by the Company as a whole or in part (whether an interest in a
specific  element  or  unit  or an undivided  interest),  to  any
Person; provided, however, that no such assignment, lease,  sale,
transfer or other disposition (a) shall relieve the Company  from
its primary liability for its obligations under Sections 5.01 and
10.01(a) hereof or (b) shall be made unless the assignee, lessee,
purchaser  or other transferee, as the case may be, prior  to  or
simultaneously  with such assignment, lease,  sale,  transfer  or
other  disposition, assumes, by delivery of an instrument to  the
Trustee   and  the  Pollution  Control  Corporation,  all   other
obligations  of  the  Company hereunder  to  the  extent  of  the
interest   assigned,  leased,  sold,  transferred  or   otherwise
disposed  of, and the Company shall be released of and discharged
from  such obligations to the extent so assumed.  Notwithstanding
the  foregoing,  (a)  if  (i)  the  Company's  interest  in  this
Agreement shall be assigned as a whole or in undivided part, (ii)
the  Company's interest in the Facilities shall be  leased  as  a
whole or in undivided part and the term of such leasehold or  the
term of any extension or extensions thereof at the option of  the
Company  shall extend beyond the maturity date of  the  Bonds  or
(iii)  the  Company's interest in the Facilities shall  be  sold,
transferred  or otherwise disposed of as a whole or in  undivided
part,  and  (b) in the event that the assignee, lessee, purchaser
or  other transferee shall assume the obligations of the  Company
under either or both of Sections 5.01 and 10.01(a) hereof for the
remaining  term  of  this  Agreement  to  the  extent   of   such
assignment,  lease,  sale,  transfer or  other  disposition,  the
Company shall be released from and discharged of all liability in
respect of such obligations to the extent so assumed (but only to
such  extent); provided, however, that if there shall  not  be  a
Security  Arrangement in effect on which the Company is  not  the
obligor,  the  release and discharge of the Company  pursuant  to
clause  (b) shall be conditioned upon delivery by the Company  to
the  Trustee  and  the Pollution Control Corporation  of  written
evidence  from  Moody's, if the Bonds are rated by  Moody's,  and
S&P,  if  the Bonds are rated by S&P, in each case to the  effect
that  such  release  and discharge of the Company,  after  giving
effect  to such assumption by the assignee, lessee, purchaser  or
other  transferee, will not, by itself, result in a reduction  or
withdrawal  of  its  ratings then in effect  on  the  Bonds;  and
provided,  further, that after any such assumption,  release  and
discharge  as  aforesaid,  the  Company  may  again  assume  such
obligations  under Section 5.01 or 10.01(a) hereof, or  both,  in
whole or in part, at any time and from time to time, and, to  the
extent  of any such assumption by the Company (but only  to  such
extent),  the  aforesaid  assignee, lessee,  purchaser  or  other
transferee shall be released from and discharged of all liability
in respect of such obligations.

   Anything  herein to the contrary notwithstanding, the  Company
shall  not make any assignment, lease or sale as provided in  the
immediately preceding paragraph unless it shall have furnished to
the  Pollution Control Corporation and the Trustee an opinion  of
Bond Counsel to the effect that the proposed assignment, lease or
sale  will not impair the validity under the Act of the Bonds  or
the  exclusion  of  interest on the Bonds from gross  income  for
federal tax purposes.

   After  any lease, sale, transfer or other disposition  of  any
element  or unit of the Facilities, or any interest therein,  the
Company  may,  at  its  option, cause such element  or  unit,  or
interest  therein,  to no longer be deemed  to  be  part  of  the
Facilities  for the purposes of this Agreement by  delivering  to
the  Pollution Control Corporation and the Trustee the agreements
or  other  documents  required pursuant to  Section  7.02  hereof
together  with  an  instrument signed by  an  Authorized  Company
Representative  stating that such element or  unit,  or  interest
therein,  shall no longer be deemed to be part of the  Facilities
for the purposes of this Agreement.

  2.029       Instrument Furnished to Trustee.  The Company shall,
within  fifteen (15) days after the delivery thereof, furnish  to
the  Pollution  Control Corporation and the Trustee  a  true  and
complete  copy of the agreements or other documents  effectuating
any such assignment, lease, sale, transfer or other disposition.

  2.030       Limitation.  This Agreement shall not be assigned nor
shall  the  Facilities be leased, sold, transferred or  otherwise
disposed  of,  in  whole or in part, except as provided  in  this
Article VII or in Section 6.01 or 5.02 hereof.


                          ARTICLE VIII

                 EVENTS OF DEFAULT AND REMEDIES

  2.031        Events  of Default.  Each of the following  events
shall  constitute  and  is referred to in this  Agreement  as  an
"Event of Default":

     (a)    a failure by the Company to make any Loan Payment or any
  payment  required under Section 10.01(a) hereof, which  failure
  shall have resulted in an "Event of Default" under clause  (a),
  (b) or (c) of Section 9.01 of the Indenture;

     (b)     a  failure by the Company to pay when due any amount
  required  to  be  paid under this Agreement or to  observe  and
  perform any covenant, condition or agreement on its part to  be
  observed or performed (other than a failure described in clause
  (a) above), which failure shall continue for a period of ninety
  (90)  days  after written notice, specifying such  failure  and
  requesting  that it be remedied, shall have been given  to  the
  Company  by  the Pollution Control Corporation or the  Trustee,
  unless the Pollution Control Corporation and the Trustee  shall
  agree  in writing to an extension of such period prior  to  its
  expiration;  provided,  however,  that  the  Pollution  Control
  Corporation and the Trustee 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

     (c)    the dissolution or liquidation of the Company, or failure
  by  the Company promptly to lift any execution, garnishment  or
  attachment of such consequence as will impair its ability to make
  any payments under this Agreement, or the entry of an order for
  relief by a court of competent jurisdiction in any proceeding for
  its  liquidation or reorganization under the provisions of  any
  bankruptcy act or under any similar act which may be  hereafter
  enacted, or an assignment by the Company for the benefit of its
  creditors,  or  the entry by the Company into an  agreement  of
  composition  with  its  creditors  (the  term  "dissolution  or
  liquidation of the Company," as used in this clause, shall not be
  construed to include the cessation of the corporate existence of
  the Company resulting either from a merger or consolidation  of
  the Company into or with another corporation or a dissolution or
  liquidation  of  the  Company following a transfer  of  all  or
  substantially all its assets as an entirety, under the conditions
  permitting such actions contained in Section 6.01 hereof).

  2.032       Force Majeure.  The provisions of Section 8.01 hereof
are subject to the following limitations: if by reason of acts of
God; strikes, lockouts or other industrial disturbances; acts  of
public  enemies;  orders or any kind of  the  government  of  the
United  States  or  of the State of Arizona, or  any  department,
agency, political subdivision, court or official of any of  them,
or   any  civil  or  military  authority;  insurrections;  riots;
epidemics; landslides; lightning; earthquakes; volcanoes;  fires;
hurricanes;   tornadoes;  storms;  floods;  washouts;   droughts;
arrests;  restraint of government and people; civil disturbances;
explosions; breakage or accident to machinery; partial or  entire
failure of utilities; or any cause or event not reasonably within
the control of the Company, the Company is unable in whole or  in
part  to  carry  out  any  one  or  more  of  its  agreements  or
obligations  contained herein, other than its  obligations  under
Sections 5.01, 5.03, 5.05, 6.01 and 10.01(a) hereof, the  Company
shall not be deemed in default by reason of not carrying out said
agreement   or  agreements  or  performing  said  obligation   or
obligations  during  the  continuance  of  such  inability.   The
Company   shall  make  reasonable  effort  to  remedy  with   all
reasonable  dispatch  the  cause or  causes  preventing  it  from
carrying  out  its agreements; provided, that the  settlement  of
strikes,  lockouts  and  other industrial disturbances  shall  be
entirely  within the discretion of the Company, and  the  Company
shall not be required to make settlement of strikes, lockouts and
other  industrial disturbances by acceding to the demands of  the
opposing party or parties when such course is in the judgment  of
the Company unfavorable to the Company.

  2.033       Remedies.  (a)  Upon the occurrence and continuance
of  any Event of Default described in clause (a) of Section  8.01
hereof,  and further upon the condition that, in accordance  with
the terms of the Indenture, the Bonds shall have been declared to
be  immediately due and payable pursuant to any provision of  the
Indenture,  the  Loan  Payments shall,  without  further  action,
become and be immediately due and payable.

   Any waiver of any "Event of Default" under the Indenture and a
rescission  and annulment of its consequences shall constitute  a
waiver of the corresponding Event or Events of Default under this
Agreement  and  a  rescission and annulment of  the  consequences
thereof.

  (a)     Upon  the  occurrence and continuance of any  Event  of
Default,  the Pollution Control Corporation, or the Trustee  with
respect  to  the  rights  of  the Pollution  Control  Corporation
assigned to the Trustee by the Indenture, may take any action  at
law  or in equity to collect any payments then due and thereafter
to  become due, or to enforce performance and observance  of  any
obligation, agreement or covenant of the Company hereunder.

  (b)     Any  amounts collected by the Trustee from the  Company
pursuant to this Section 8.03 shall be applied in accordance with
the Indenture.

  2.034        No Remedy Exclusive.  No remedy conferred upon  or
reserved  to the Pollution Control Corporation hereby is intended
to  be  exclusive of any other available remedy or remedies,  but
each  and every such remedy shall be cumulative and shall  be  in
addition  to  every  other  remedy  given  hereunder  or  now  or
hereafter existing at law or in equity or by statute.   No  delay
or  omission  to  exercise any right or power accruing  upon  any
default  shall  impair  any  such right  or  power  or  shall  be
construed to be a waiver thereof, but any such right or power may
be  exercised  from time to time and as often as  may  be  deemed
expedient.  In order to entitle the Pollution Control Corporation
to  exercise any remedy reserved to it in this Article  VIII,  it
shall not be necessary to give any notice, other than such notice
as may be herein expressly required.

  2.035       Reimbursement of Attorneys' and Agents' Fees.  If the
Company shall default under any of the provisions hereof and  the
Pollution  Control  Corporation  or  the  Trustee  shall   employ
attorneys  or agents or incur other reasonable expenses  for  the
collection  of  payments due hereunder or for the enforcement  of
performance or observance of any obligation or agreement  on  the
part  of the Company contained herein, the Company will on demand
therefor  reimburse  the  Pollution Control  Corporation  or  the
Trustee and any predecessor Trustee, as the case may be, for  the
reasonable  fees  of  such attorneys and  such  other  reasonable
expenses so incurred.

  2.036        Waiver  of  Breach.  In the event  any  obligation
created  hereby  shall be breached by either of the  parties  and
such  breach shall thereafter be waived by the other party,  such
waiver  shall be limited to the particular breach so  waived  and
shall not be deemed to waive any other breach hereunder.  In view
of   the   assignment   of  certain  of  the  Pollution   Control
Corporation's rights and interest hereunder to the  Trustee,  the
Pollution  Control Corporation shall have no power to  waive  any
breach  hereunder by the Company in respect of  such  rights  and
interest without the consent of the Trustee, and the Trustee  may
exercise  any of the rights of the Pollution Control  Corporation
hereunder.


                           ARTICLE IX

                      REDEMPTION OF BONDS

  2.037         Redemption  of  Bonds.   The  Pollution   Control
Corporation  shall  take,  or cause  to  be  taken,  the  actions
required  by the Indenture to discharge the lien created  thereby
through  the  redemption, or provision for payment or redemption,
of  all  Bonds then Outstanding, or to effect the redemption,  or
provision  for payment or redemption, of less than all the  Bonds
then   Outstanding,   upon  receipt  by  the  Pollution   Control
Corporation  and  the  Trustee  from  the  Company  of  a  notice
designating the principal amount of the Bonds to be redeemed,  or
for  the payment or redemption of which provision is to be  made,
and,  in  the case of redemption of Bonds, or provision therefor,
specifying  the date of redemption and the applicable  redemption
provision  of the Indenture.  Such redemption date shall  not  be
less  than  45 days from the date such notice is given (unless  a
shorter notice is satisfactory to the Trustee).  Unless otherwise
stated therein, such notice shall be revocable by the Company  at
any time prior to the time at which the Bonds to be redeemed,  or
for  the payment or redemption of which provision is to be  made,
are  first deemed to be paid in accordance with Article  VIII  of
the   Indenture.   The  Company  shall  furnish  any  moneys   or
Government Obligations (as defined in the Indenture) required  by
the  Indenture to be deposited with the Trustee or otherwise paid
by  the  Pollution Control Corporation in connection with any  of
the foregoing purposes.

  2.038        Compliance with the Indenture.  Anything  in  this
Agreement to the contrary notwithstanding, the Pollution  Control
Corporation  and the Company shall take all actions  required  by
this  Agreement  and the Indenture in order to  comply  with  any
provisions of the Indenture requiring the mandatory redemption of
Bonds.


                           ARTICLE X

  2.039        Purchase  of Bonds.  (a) In consideration  of  the
issuance  by the Pollution Control Corporation of the Bonds,  but
for  the  benefit  of the owners of the Bonds,  the  Company  has
agreed,   and  does  hereby  covenant,  to  cause  the  necessary
arrangements  to  be made and to be thereafter continued  whereby
Owners  from  time  to time of the Bonds may  deliver  Bonds  for
purchase  and  whereby  such Bonds shall  be  so  purchased.   In
furtherance  of  the  foregoing  covenant  of  the  Company,  the
Pollution  Control Corporation, at the direction of the  Company,
has  set  forth  in Section 2.02 of the Indenture the  terms  and
conditions  relating  to  the delivery of  Bonds  by  the  Owners
thereof  for  purchase,  has set forth in  Article  XIII  of  the
Indenture  the  duties and responsibilities of the  Tender  Agent
with  respect  to  the purchase of Bonds, and of the  Remarketing
Agent  with  respect to the remarketing of Bonds and has  therein
provided  for the appointment by the Company of the Tender  Agent
and  the  Remarketing Agent.  The Company hereby  authorizes  and
directs  the Tender Agent and the Remarketing Agent to  purchase,
offer,  sell and deliver Bonds in accordance with the  provisions
of Article XIII of the Indenture.

   In consideration of the Pollution Control Corporation's having
set  forth  in the Indenture the aforesaid provisions of  Section
2.02 and the Article XIII thereof, the Company covenants, for the
benefit of the owners of Outstanding Bonds, to pay, cause  to  be
paid,  to  the Tender Agent for the account of such holders  such
amounts  as  shall  be necessary to effect  the  payment  of  the
purchase  price of Outstanding Bonds delivered for purchase,  all
as  more particularly described in Sections 2.02 and 13.03 of the
Indenture; provided, however, that the obligation of the  Company
to  make any such payment hereunder to the Tender Agent shall  be
reduced  by  the amount of any moneys available for such  payment
described in clause (i), (iii) or (iv) of Section 13.03(a) of the
Indenture;  and  provided, further, that such obligation  of  the
Company  shall  be deemed to be satisfied and discharged  to  the
extent  of  the corresponding payment made by the obligor  (other
than the Company) under any Security Arrangement.

  (a)    The Pollution Control Corporation shall have no obligation
or  responsibility, financial or otherwise, with respect  to  the
purchase  of  Bonds or the making or continuation of arrangements
therefor other than as expressly set forth in subsection  (a)  of
this Section 10.01, except that the Pollution Control Corporation
shall generally cooperate with the Company, the Tender Agent  and
the  Remarketing  Agent as contemplated in Article  XIII  of  the
Indenture.

  2.040       Optional Purchase of Bonds.  The Company may at any
time,  and from time to time, furnish moneys to the Tender  Agent
accompanied  by a notice directing such moneys to be  applied  to
the  purchase  of  Bonds delivered for purchase pursuant  to  the
terms  of  the Indenture, which Bonds shall be delivered  to  the
Trustee  for cancellation in accordance with Section 13.07(b)  of
the  Indenture.   The  Company shall deliver to  the  Remarketing
Agent and the Bank a copy of any such notice.


                           ARTICLE XI

                         MISCELLANEOUS

  2.041       Term of Agreement.  This Agreement shall remain  in
full force and effect from the date hereof until the right, title
and  interest  of  the  Trustee in and to the  Trust  Estate  (as
defined  in  the  Indenture) shall have  ceased,  terminated  and
become void in accordance with Article VIII of the Indenture  and
until all payments required under this Agreement shall have  been
made.   Notwithstanding the foregoing, the covenant contained  in

  2.043       Parties in Interest.  This Agreement shall inure to
the  benefit  of and shall be binding upon the Pollution  Control
Corporation,  the  Company  and their respective  successors  and
assigns, and no other person, firm or corporation shall have  any
right,  remedy  or  claim under or by reason of  this  Agreement;
provided, however, that the lien and security interest granted to
the  Trustee  in Section 4.03 hereof, as well as the  rights  and
remedies granted to the Pollution Control Corporation in  Article
VIII hereof, shall inure to the benefit of the Trustee, on behalf
of  the  owners  from  time to time of the Bonds,  and  shall  be
enforceable  by  the Trustee as a third party beneficiary  or  as
assignee  of  the  Pollution Control Corporation;  and  provided,
further,  that  the  obligations of  the  Company  under  Section
10.01(a)  hereof shall inure to the benefit of the Tender  Agent,
on behalf of the owners from time to time of the Bonds, and shall
be  enforceable by the Tender Agent as a third party beneficiary;
and  provided,  further,  that neither the  County  of  Coconino,
Arizona nor the State of Arizona shall in any event be liable for
the  payment of the principal of or premium, if any, or  interest
on  the  Bonds  or  for the performance of any pledge,  mortgage,
obligation  or  agreement  created by  or  arising  out  of  this
Agreement or the issuance of the Bonds, and further that  neither
the  Bonds  nor any such obligation or agreement of the Pollution
Control   Corporation  shall  be  construed  to   constitute   an
indebtedness of the County of Coconino, Arizona or the  State  of
Arizona  within  the meaning of any constitutional  or  statutory
provisions  whatsoever, but shall be limited obligations  of  the
Pollution Control Corporation payable solely out of the  revenues
derived  from this Agreement or any Security Arrangement provided
hereunder,  or from the sale of the Bonds, or from the investment
or  reinvestment of any of the foregoing, as provided herein  and

limitations set forth herein and in the Indenture.

  2.045       Counterparts.  This Agreement may be executed in any
number  of  counterparts, each of which,  when  so  executed  and
delivered,  shall  be  an original; but such  counterparts  shall
together constitute but one and the same Agreement.

  2.046       Severability.  If any clause, provision or section of
this  Agreement shall, for any reason, be held illegal or invalid
by  any  court,  the  illegality or invalidity  of  such  clause,
provision  or  section  shall not affect  any  of  the  remaining
clauses, provisions or sections hereof, and this Agreement  shall
be  construed and enforced as if such illegal or invalid  clause,
provision or section had not been contained herein.  In case  any
agreement or obligation contained in this Agreement be held to be
in  violation of law, then such agreement or obligation shall  be
deemed to be the agreement or obligation of the Pollution Control
Corporation  or  the Company, as the case may  be,  to  the  full
extent permitted by law.

  2.047        Governing Law.  The laws of the State  of  Arizona

   The Company covenants and agrees not to employ as an employee,
agent or, with respect to the subject matter of this Agreement, a

II                      THE BONDS

  II.11.         Creation  of  Bonds.   There  is   hereby
authorized  and  created  under this  Indenture,  for  the
purpose  of providing moneys to pay a part of the Cost  of
Construction, an issue of Bonds, entitled to the  benefit,
protection  and  security  of  this  Indenture,   in   the
aggregate  principal  amount  of  Sixteen  Million   Seven
Hundred Thousand Dollars ($16,700,000).  Each of the Bonds
shall be designated by the title "Coconino County, Arizona
Pollution  Control Corporation Pollution  Control  Revenue
Bond,   1996  Series  A  (Tucson  Electric  Power  Company
Project)".   The  Bonds  shall mature,  subject  to  prior
redemption  upon the terms and conditions hereinafter  set
forth, on May 1, 2031.

  II.12.       Interest on the Bonds. The Bonds shall bear
interest,  payable on each Interest Payment Date,  at  the
lesser of (a) a Daily Rate, a Weekly Rate, a Monthly Rate,
a Flexible Rate or Rates, a Term Rate or the Fixed Rate as
selected  by  the Company in accordance with this  Section
2.02 and (b) 12% per annum (the "Maximum Rate"). The Bonds
shall initially bear interest at a Weekly Rate.  When  the
Bonds bear interest at a Variable Rate (other than a  Term
Rate) or at Flexible Rates, interest shall be computed  on
the basis of the actual number of days elapsed over a year
of  365  days  (366 in leap years).  When the  Bonds  bear
interest at a Term Rate or the Fixed Rate, interest  shall
be  computed on the basis of a 360-day year of twelve  30-
day  months.   For  purposes of any  such  calculation  of
interest  payable  with  respect  to  the  final  interest
payment during a Term Rate Period immediately followed  by
a  Flexible,  Daily, Weekly or Monthly  Rate  Period,  the
amount of interest which shall be payable with respect  to
such  final interest period shall be determined as if  the
Interest  Payment Date for such period were the first  day
of  the  sixth  month  following  the  preceding  Interest
Payment Date, notwithstanding any extension of such  month
to  the first Business Day of such month by reason of  the
conversion to such Flexible, Daily, Weekly or Monthly Rate
Period.   Interest  shall be paid on  each  Bond  on  each
Interest Payment Date for such Bond. Each Bond shall  bear
interest  from the Interest Payment Date to which interest
thereon  shall  have  been  paid  in  full  which  is,  or
immediately precedes, its date of authentication,  or,  if
no  interest shall have been paid on the Bonds,  from  the
date of initial authentication and delivery of Bonds under
this Indenture.

    While  there exists an Event of Default, the  interest
rate   on  the  Bonds  will  be  the  rate  on  the  Bonds
immediately  prior  to the occurrence  of  such  Event  of
Default,  except that if the Bonds then bore  interest  at
Flexible  Rates  the rate during the continuance  of  such
Event of Default will be the highest Flexible Rate then in
effect  for  any  Bond.  The interest  rate  determination
method  may  be  changed by the Company  as  described  in
Sections  2.02(c)  and  2.02(d) hereof.   The  methods  of
determining the various interest rates are as provided  in
Sections  2.02(b)  and 2.02(d) hereof.  The  various  Rate
Periods  are  described  in Section  2.02(a)  and  2.02(d)
hereof.

    Notwithstanding any provision of this Indenture or  of
any  Bond, the Trustee or the Paying Agent may, but  shall
not  be  obligated  to, enter into an agreement  with  any
Owner  of 100% in aggregate principal amount of the  Bonds
providing for making any or all payments to that Owner  of
principal or redemption price of and interest on the Bonds
or  any part thereof (other than any payment of the entire
unpaid  principal  amount thereof) at a  place  and  in  a
manner other than as provided in this Indenture and in the
Bonds, without presentation or surrender of the Bonds, and
for   giving  any  notice  required  hereunder,  upon  any
conditions that shall be satisfactory to the Trustee,  the
Paying  Agent  and  the  Company; provided  that  no  such
agreement with such an Owner shall provide for less notice
than is otherwise provided for herein.

    The  Trustee or the Paying Agent, as the case may  be,
will furnish a copy of each of those agreements, certified
to  be the document executed by an officer of the Trustee,
to the Company. Any payment of principal, redemption price
or interest pursuant to such an agreement shall constitute
payment thereof pursuant to, and for all purposes of, this
Indenture.

     (a)     Rate Periods.

     (i)    Flexible Rate Periods. The Flexible Rate Period for
  each  Bond shall be of such duration, not exceeding  270
  days,  as  may be offered by the Remarketing  Agent  and
  specified by the purchaser pursuant to Section 2.02(b)(i)
  hereof, and any Bond may bear interest at a Flexible Rate,
  and have a Flexible Rate Period, different from any other
  Bond; provided that each such Flexible Rate Period shall
  (A)  commence on a Business Day (initially, the Flexible
  Rate  Conversion Date), and (B) end on a  day  which  is
  immediately followed by a Business Day.

     (ii)    Daily Rate Periods. Daily Rate Periods  shall
  commence on each Business Day and shall extend to, but not
  include, the next succeeding Business Day.

     (iii)       Weekly Rate Periods. Weekly Rate Periods shall
  commence on Wednesday of each week and end on Tuesday of
  the  following week; except that (A) in the  case  of  a
  conversion  to a Weekly Rate Period, the initial  Weekly
  Rate  Period for Bonds shall commence on the Weekly Rate
  Conversion Date and end on Tuesday of the following week;
  and  (B) in the case of a conversion from a Weekly  Rate
  Period to a different Rate Period, the last Weekly  Rate
  Period  prior  to conversion shall end on the  last  day
  immediately preceding the Conversion Date.

     (iv)   Monthly Rate Periods.   Monthly Rate Periods shall
  (A)  commence on a Monthly Rate Conversion  Date,  which
  shall be the first Business Day of a month and the first
  Business Day of each calendar month thereafter, and  (B)
  end on the last day preceding either the commencement date
  of the following Monthly Rate Period or a Conversion Date
  on  which  a different type of Rate Period shall  become
  effective.

     (v)    Term Rate Periods.  Term Rate Periods shall (A)
  commence on a Term Rate Conversion Date; and (B) end  on
  the last day preceding either the commencement date of the
  following Term Rate Period or the Conversion Date on which
  a different Rate Period shall become effective.

  (b)    Determination of Interest Rates.  The interest rate
for  the Bonds for each Rate Period (other than a Flexible
Rate Period), shall be determined by the Remarketing Agent
to  be  the lowest rate of interest which, in the judgment
of  the  Remarketing Agent as of the date of determination
and  under  prevailing market conditions, would cause  the
Bonds to have a market value equal to the principal amount
thereof,  plus accrued and unpaid interest, if  any.   The
interest rate shall be determined by the Remarketing Agent
for each Rate Period as follows:

     (i)    Flexible Rates. The Flexible Rate for each Flexible
  Rate  Period  shall be effective from and including  the
  commencement date of such period to and including the last
  day thereof. Each Flexible Rate, and Flexible Rate Period,
  shall be determined by the Remarketing Agent in connection
  with  the sale of the Bond or Bonds to which it relates.
  Each  Flexible Rate, and Flexible Rate Period, shall  be
  determined for each Bond on or prior to the first day of
  each Flexible Rate Period with respect to such Bond by the
  Remarketing Agent by the offer and acceptance of purchase
  commitments for such Bond (at a price equal to 100% of the
  principal amount) for such Flexible Rate Period and/or for
  such Flexible Rate as the Remarketing Agent deems to  be
  advisable in order to minimize the net interest cost  on
  the  Bonds under prevailing market conditions; provided,
  however,  that  the  foregoing shall  not  prohibit  the
  Remarketing Agent from accepting purchase commitments for
  longer  Flexible  Rate Periods (and at  higher  Flexible
  Rates)  than are otherwise available at the time of  any
  remarketing if the Remarketing Agent determines, in  its
  sole judgment, that, under prevailing market conditions, a
  lower net interest cost on the Bonds can be achieved over
  the  longer  Flexible  Rate Period. Notwithstanding  the
  foregoing,  no  Flexible Rate Period may be  established
  which exceeds 270 days or, if the Remarketing Agent  has
  given or received notice of any conversion to a Variable
  or Fixed Rate Period, the remaining number of days prior
  to the Conversion Date. If for any reason a Flexible Rate
  shall not be determined for any Flexible Rate Period for
  any Bond, the Flexible Rate for such Flexible Rate Period
  for such Bond shall be the Flexible Rate in effect for the
  immediately preceding Flexible Rate Period, or a Flexible
  Rate  Period shall not be determined for any  Bond,  the
  Flexible Rate Period for such Bond shall be the shortest
  period encompassing at least one Business Day.

     (ii)   Daily Rates. The Daily Rate for each Daily Rate
  Period  shall  be  effective  from  and  including   the
  commencement date thereof and shall remain in effect from
  day  to day until changed by the Remarketing Agent.  The
  initial Daily Rate and any change to the Daily Rate shall
  be determined by the Remarketing Agent between 1:00 p.m.,
  New  York  City  time, on the Business  Day  immediately
  preceding the commencement date of the Daily Rate Period
  to which it relates and 10:00 a.m., New York City time, on
  such commencement date.

     (iii)       Weekly Rates. The Weekly Rate for each Weekly
  Rate  Period  shall be effective from and including  the
  commencement  date of such period and  shall  remain  in
  effect through and including the last day thereof.  Each
  such  Weekly Rate shall be determined by the Remarketing
  Agent not later than 4:00 p.m., New York City time, on the
  Tuesday or the next Business Day immediately preceding the
  commencement date of the Weekly Rate Period to which  it
  relates.

     (iv)   Monthly Rates. The Monthly Rate for each Monthly
  Rate  Period  shall be effective from and including  the
  commencement  date of such period and  shall  remain  in
  effect  through and including the last day thereof.  The
  Monthly  Rate  for  each Monthly Rate  Period  shall  be
  determined not later than 4:00 pm., New York City time, on
  the  Business Day immediately preceding the commencement
  date of the Monthly Rate Period to which it relates.

     (v)    Term Rates. The Term Rate for each Term Rate Period
  shall  be  effective from and including the commencement
  date of such period and shall remain in effect through and
  including the last day thereof.  Each Term Rate shall be
  determined by the Remarketing Agent not later than  4:00
  p.m., New York City time, on the Business Day immediately
  preceding the commencement date of the Term Rate Period to
  which it relates.  If for any reason the duration of any
  Term  Rate Period shall not be determined for such  Term
  Rate Period, such duration shall be one year.

     (vi)   Non-Determination. If for any reason a Weekly Rate,
  Monthly Rate or Term Rate shall not be determined for  a
  Weekly  Rate  Period, Monthly Rate Period or  Term  Rate
  Period, the Weekly Rate, Monthly Rate or Term Rate, as the
  case  may be, shall be the Weekly Rate, Monthly Rate  or
  Term  Rate in effect for the immediately preceding  Rate
  Period.

  (c)     Conversions between Rate Periods. In addition to
any  conversion  to  the Fixed Rate  pursuant  to  Section
2.02(d)  hereof, at the option of the Company,  the  Bonds
may  be  converted  from the one type of  Rate  Period  to
another as follows:

     (i)    The Conversion Date for a conversion to a different
  Rate  Period shall be an Interest Payment Date on  which
  interest  is payable for the Rate Period from which  the
  conversion is to be made; provided, however, that:

       (A)    if the conversion is from Flexible Rate Periods,
     the Conversion Date shall be the last Interest Payment
     Date on which interest is payable for any Flexible Rate
     Periods theretofore established for the Bonds;

       (B)    if the conversion is from a Term Rate Period to a
     Term Rate Period of a different duration or to a different
     Rate Period, the Conversion Date may only be the last
     Interest Payment Date in respect of that Term Rate Period;
     and

       (C)    if the conversion is between Daily and Weekly Rate
     Periods,  the  Conversion Date may be any  Wednesday,
     regardless of whether the Wednesday is an Interest Payment
     Date.

     (ii)   The Company shall give written notice of any such
  conversion  to the Remarketing Agent, the  Trustee,  the
  Tender Agent and the Bank not fewer than thirty-five (35)
  days  prior to the proposed Conversion Date. Such notice
  shall specify the proposed Conversion Date and the type of
  Rate Period to which the conversion will be made, and in
  the case of conversion to a Term Rate Period, the number
  of years to be included within such Term Rate Period.

     (iii)       Not more than sixty (60) days prior to the
  Conversion Date and not fewer than thirty (30) days prior
  to the Conversion Date, the Tender Agent shall give Notice
  by  Mail  of the conversion to the Owners of  the  Bonds
  stating the proposed Conversion Date and the proposed type
  of  Rate  Period and, except in the case of  conversions
  between Daily and Weekly Rate Periods, stating that  the
  Bonds will bc subject to mandatory tender for purchase on
  the  Conversion Date at a purchase price  equal  to  the
  principal  amount thereof. The notice shall state:   (A)
  that all Bonds must be delivered to the Tender Agent for
  mandatory purchase on the Conversion Date at a  purchase
  price equal to the principal amount thereof and that  if
  the Owner fails to deliver any Bonds to the Tender Agent
  on the purchase date and the Tender Agent is in receipt of
  the purchase price therefor, such Bonds shall be deemed to
  be   purchased  on  the  purchase  date  and   ownership
  transferred  to the purchaser thereof, and (B)  that  an
  Owner  who  fails to deliver such Bonds  shall  have  no
  further rights thereunder except the right to receive the
  purchase price thereof upon presentation and surrender of
  such Bond to the Tender Agent.

     (iv)   Any conversion to a different Rate Period (except a
  conversion, if any, between Daily and Weekly Rate Periods)
  pursuant to this Section 2.02(c) shall be subject to the
  condition  that  on or before the Conversion  Date,  the
  Company  shall  have delivered to the Pollution  Control
  Corporation,  the  Trustee, the  Tender  Agent  and  the
  Remarketing Agent an opinion of Bond Counsel to the effect
  that the conversion is authorized hereunder and under the
  Act and will not, in and of itself, adversely affect the
  exclusion from gross income for federal tax purposes  of
  the interest on the Bonds.

     (v)    While the Letter of Credit shall be in effect, the
  Bonds  shall not be converted to a Term Rate  Period  or
  Flexible Rate Period unless the Letter of Credit may  be
  drawn  upon  (in respect of interest or the  portion  of
  purchase  price equal to accrued interest) in an  amount
  which  equals at least 210 days accrued interest in  the
  case of a Term Rate Period or 300 days accrued interest in
  the case of a Flexible Rate Period.

  (d)    The Fixed Rate. At the option of the Company, the
  Bonds may be converted to bear interest at a Fixed Rate to
  their final maturity. Any such conversion shall be made as
  follows:

     (i)    The Fixed Rate Conversion Date shall be an Interest
  Payment  Date on which interest is payable for the  Rate
  Period from which the conversion is to be made; provided,
  however, that (A) if the conversion is from a Term  Rate
  Period, the Fixed Rate Conversion Date shall be limited to
  an Interest Payment Date on which a new Term Rate Period
  would otherwise have commenced and (B) if the conversion
  is from a Flexible Rate Period, the Fixed Rate Conversion
  Date shall be an Interest Payment Date on which interest
  is payable for all Bonds.

     (ii)   (A)  The Company shall give written notice of any
  such conversion to the Pollution Control Corporation, the
  Trustee, the Remarketing Agent, the Tender Agent and the
  Bank  not fewer than forty-five (45) days prior  to  the
  proposed Conversion Date. Such notice shall specify  the
  Fixed Rate Conversion Date.

     (A)    Not fewer an thirty (30) nor more than sixty (60)
  days prior to the Fixed Rate Conversion Date, the Tender
  Agent shall give Notice by Mail of the conversion to the
  Owners  of all Bonds, specifying the proposed Conversion
  Date  and  stating  that the Bonds will  be  subject  to
  mandatory tender for purchase on the Conversion Date. The
  notice shall state that all Bonds must be delivered to the
  Tender Agent for mandatory purchase on the Conversion Date
  at a purchase price equal to the principal amount thereof
  and  that if the Owner fails to deliver any Bonds to the
  Tender Agent on the purchase date and the Tender Agent is
  in  receipt  of the purchase price therefor, such  Bonds
  shall be deemed to be purchased on the purchase date and
  ownership transferred to the purchaser thereof and that an
  Owner  who  fails to deliver such Bonds  shall  have  no
  further rights thereunder except the right to receive the
  purchase price thereof upon presentation and surrender of
  such Bond to the Tender Agent.

     (iii)       The Fixed Rate shall be determined by the
  Remarketing Agent no later than 3:00 pm., New York  City
  time,  on  the  Business Day preceding  the  Fixed  Rate
  Conversion Date. The Fixed Rate shall be the lowest rate
  of  interest  which, in the judgment of the  Remarketing
  Agent as of the date of determination and under prevailing
  market conditions, would cause the Bonds to have a market
  value equal to the principal amount thereof.

     (iv)   Any conversion to a Fixed Rate shall be subject to
  the condition that on or before the Fixed Rate Conversion
  Date,  the Company shall have delivered to the Pollution
  Control Corporation, the Trustee, the Tender Agent and the
  Remarketing Agent an opinion of Bond Counsel to the effect
  that the conversion is authorized hereunder and under the
  Act and will not, in and of itself, adversely affect the
  exclusion from gross income for federal tax purposes  of
  the interest on the Bonds.

  (e)     Calculation of Interest.  The Remarketing  Agent
will notify the Trustee and the Company, in writing or  by
telecopy  or telephone promptly confirmed by tested  telex
by 4:00 p.m., New York City time:

     (i)     on the last Business Day of a month in  which
  interest on the Bonds is payable at a Variable Rate other
  than Term Rate, of the Variable Rate for each day in such
  month;

     (ii)   on the first Business Day of each Flexible Rate
  Period, of the length thereof, the Flexible Rate therefor
  and the principal amount of Bonds bearing interest at such
  Flexible Rate; and

     (iii)       on the day of a determination thereof, of the
  Term Rate and the Fixed Rate.

Using the rates supplied by the Remarketing Agent pursuant
to  this  Section, the Trustee will calculate the interest
payable  on the Bonds.  The Remarketing Agent will  inform
the  Tender Agent and the Bank orally at the oral  request
of any of them of any interest rate set by the Remarketing
Agent.   The  Trustee  will  use  commercially  reasonable
efforts to respond to telephonic inquiries from Owners  of
Bonds with respect to the effective interest rate.

    The  setting  of  the  rates and  the  calculation  of
interest  payable  on  the  Bonds  as  provided  in   this
Indenture  will be conclusive and binding on  all  parties
and on each Owner of a Bond.

  (f)    Change in Rate Periods-Opinion or Opinions of Bond
Counsel.  Notwithstanding any provision  of  this  Section
2.02,  no change shall be made in the Rate Period pursuant
to  Section  2.02(c) or 2.02(d) hereof if the  opinion  or
opinions of Bond Counsel required under Section 2.02(c) or
2.02(d)  hereof  are  not  delivered  on  or  before   the
Conversion Date.  If the Tender Agent shall have sent  any
notice  to  the Owners of the Bonds regarding a change  in
the  Rate  Period,  then  in the  event  such  opinion  or
opinions  are  not  delivered,  the  Tender  Agent   shall
promptly  notify  by  commercially  reasonable  means  all
Owners  of  the  Bonds that the proposed  change  in  Rate
Period  shall not occur and that the existing Rate  Period
shall continue in effect.

  (g)    Optional Tenders for Purchase during Variable Rate
Periods.

     (i)    Owners of Bonds bearing interest at Variable Rates
  may  elect  to have their Bonds (or portions thereof  in
  amounts equal to the lowest denomination then authorized
  or whole multiples of such lowest denomination) purchased
  at a purchase price equal to 100% of the principal amount
  of  such  Bonds (or portions thereof), plus,  except  as
  hereinafter provided, accrued and unpaid interest, if any,

     telephonic notice, promptly confirmed in writing)  of

     York City time, on a Business Day not fewer than seven (7)
     days prior to the purchase date.

       (C)    Bonds bearing interest at Monthly Rates may be

     tendered for purchase on the commencement date of the
     succeeding Rate Period at a price payable in immediately

       (A)    shall (y) in the case of a written notice, except
     as otherwise specified, be delivered by or on behalf of
     the Owner to the Tender Agent at its Principal Office, and
     be in form satisfactory to the Tender Agent; and (z) in

     DTC  as  DTC shall designate and held by DTC  in  its
     book-entry system, notice to the Tender Agent shall be in
     the form set forth as Exhibit D hereto.

           II.0(J)   shall  state,  whether  delivered  in
     writing  or  by  telephone  (promptly  confirmed   in
     writing)  (w)  the principal amount of  the  Bond  or
     Bonds to which the notice relates, (x) that the Owner
     irrevocably demands purchase of such Bond or Bonds or
     a specified portion thereof in an amount equal to the
     lowest  denomination  then  authorized  or  a   whole
     multiple of such lowest denomination, (y) the date on
     which such Bond or Bonds or portion thereof is to  be
     purchased, and (z) payment instructions with  respect

     in writing or by telephone, (w) an irrevocable offer to
     sell  the Bond or portion thereof to which the notice
     relates on the purchase date to any purchaser selected by
     the Remarketing Agent, at a price equal to the principal
     amount of such Bond or portion thereof plus, with respect
     to Bonds bearing interest at Daily Rates or Weekly Rates,
     any interest thereon accrued and unpaid as of the purchase
     date, except that Bonds held at DTC and for which  an
     optional tender has been made by delivery of the notice
     set  forth as Exhibit D hereto shall not be purchased
     unless such Bonds are transferred to the account of the
     Tender  Agent on the tender date as provided in  such
     notice, (x) an irrevocable authorization and instruction
     to the Tender Agent to effect the transfer of such Bond or
     portion thereof upon payment of such price to the Tender
     Agent  on  the  purchase  date,  (y)  an  irrevocable
     authorization and instruction to the Tender Agent  to
     effect the exchange of the Bond to be purchased in whole

     portion thereof to be purchased, and (z) an acknowledgment
     that such Owner will have no further rights with respect
     to  such Bond or portion thereof upon payment of  the
     purchase price thereof to the Tender Agent on the purchase
     date, except for the right of such Owner to receive such
     purchase price upon surrender of such Bond.

           The  determination of the Tender  Agent  as  to
     whether   a  notice  of  tender  has  been   properly
     delivered   pursuant  to  the   forgoing   shall   be
     conclusive  and  binding upon the Owner.  The  Tender
     Agent  may  waive  any  conditions  to  a  conforming
     tender.

     (iii)       Not later than 11:00 a.m., New York City time,
  on  the  Business Day immediately following the date  of
  receipt of any notice of tender (or immediately upon such
  receipt, in the case of Bonds bearing interest at  Daily
  Rates),  the  Tender  Agent shall notify,  by  telephone
  promptly  confirmed in writing, in the case of a  Daily,
  Weekly or Monthly Rate, and in writing in all other cases,
  the  Trustee, the Remarketing Agent, the Company and the
  Bank  of  the  principal amount of  Bonds  (or  portions
  thereof) to be purchased and the date of purchase.

  (h)    Mandatory Tenders for Purchase.

     (i)    Each Bond bearing interest at a Flexible Rate shall
  be  subject to mandatory tender for purchase on the  day
  immediately following the last day of each Flexible Rate
  Period applicable to such Bond at a purchase price equal
  to  100%  of  the  principal amount  thereof;  provided,
  however, that any such Bond shall not be subject to such
  mandatory tender for purchase if, prior to 3:00 p.m.  on
  the  Business Day next preceding the day such  mandatory
  tender would otherwise occur hereunder, the Owner of such
  Bond  by  notice  delivered in writing or  by  telephone
  (promptly confirmed in writing) to the Remarketing Agent
  shall have elected to retain such Bond for an additional
  Flexible Rate Period and such Owner shall have agreed with
  the Remarketing Agent as to the duration of the additional
  Flexible Rate Period and the Flexible Rate to be effective
  during such period.

     (ii)   Bonds to be converted to the Fixed Rate or from one
  type  of  Rate Period to another (other than conversions
  between Daily and Weekly Rate Periods) or from any  Term
  Rate Period to a Term Rate Period of a different duration
  are  subject  to mandatory tender for purchase  on  such
  Conversion Date at a purchase price equal to 100% of the
  principal amount thereof.

     (iii)       Bonds shall be subject to mandatory tender for
  purchase  at  a purchase price that would  be  the  then
  applicable redemption price set forth in Section 3.01 (a)
  or (c) hereof if such Bonds were redeemed on such day, on
  the  first  day of the month in which the Expiration  or
  Termination of the term of any Security Arrangement shall
  occur;  provided, however, that there shall be  no  such
  mandatory  tender  if  prior to  the  giving  of  notice
  described in Section 2.10 hereof, (A) the Company  shall
  have delivered to the Tender Agent a certificate or letter
  from Moody's, if the Bonds are then rated by Moody's, and
  from  S&P,  if the Bonds are then rated by S&P,  to  the
  effect that the Termination or Expiration of such Security
  Arrangement,   or  the  Termination  of  such   Security
  Arrangement  and  the  provision  of  another   Security
  Arrangement in lieu thereof, as the case may be, will not,
  by  itself, result in a reduction or withdrawal  of  its
  ratings  then in effect on the Bonds and (B) if  another
  Security  Arrangement is to be provided in lieu thereof,
  such  substitute  Security Arrangement shall  have  been
  delivered to the Trustee and shall, by its terms, become
  effective on or before the Expiration or Termination  of
  the term of any existing Security Arrangement.

  (iv)    Bonds  are  subject  to  mandatory  tender   for
  purchase  at  a  purchase price equal  to  100%  of  the
  principal  amount thereof plus accrued interest  to  the
  date  of purchase, upon the occurrence of either of  the
  following events:

           (A) receipt by the Trustee, following a drawing
     on  a Security Arrangement on which the Company shall
     not  be  the obligor to pay accrued interest, or  the
     portion  of purchase price equal to accrued interest,
     on the Bonds, of notice from the Bank that the amount
     available  to  be drawn on such Security  Arrangement
     will  not  be  reinstated (in respect of interest  or
     portion  of purchase price equal to accrued interest)
     in  the  amount of such drawing, unless  such  notice
     also  directs  the Trustee to provide notice  to  the
     Pollution  Control Corporation of its  obligation  to
     redeem  the Bonds pursuant to Section 3.01(f) hereof;
     or

           (B)  receipt by the Trustee of notice from  the
     Bank  stating  that  an Event of  Default  under  the
     Reimbursement  Agreement (or other agreement  between
     the  Company and the Bank pursuant to which the  Bank
     issued  and  delivered  to  the  Trustee  a  Security
     Arrangement)  has occurred and is continuing,  unless
     such  notice  also  directs the  Trustee  to  provide
     notice  to the Pollution Control Corporation  of  its
     obligation  to redeem the Bonds pursuant  to  Section
     3.01(f) hereof.

  Upon the occurrence of an event specified in clause  (A)
  or  (B)  of  the  immediately preceding  paragraph,  the
  Trustee  shall direct the Tender Agent to purchase,  and
  the  Tender Agent shall purchase, the Bonds on the first
  Business  Day after the receipt by the Trustee  of  such
  notice  on  which  the Trustee may  make  a  drawing  or
  drawings  on such Security Arrangement and on which  the
  proceeds   of   such  drawing  or  drawings   shall   be
  immediately available, but not prior to such date.

  II.13.       Form of Bonds.  Bonds shall be authenticated
and  delivered hereunder solely as fully registered  bonds
without  coupons  in  the  denomination  of  $100,000   or
integral  multiples thereof in the case of  Bonds  bearing
interest  at  a  Variable  Rate  other  than  Term  Rates,
$100,000 or integral multiples of $5,000 in excess thereof
in  the case of Bonds bearing interest at a Flexible  Rate
and  $5,000 or integral multiples thereof, in the case  of
bonds  bearing interest at Term Rates or the  Fixed  Rate.
Bonds  shall be numbered as determined by the Trustee  and
shall be dated the date of the initial authentication  and
delivery thereof.

    Principal  of and premium, if any, on Bonds  shall  be
payable to the Owners of such Bonds upon presentation  and
surrender  of  such Bonds at the Principal Office  of  the
Paying  Agent  or  any Co-Paying Agent.  Interest  on  the
Bonds  shall be paid by check drawn upon the Paying  Agent
and mailed to the Owners of such Bonds as of the close  of
business  on the Record Date with respect to each Interest
Payment Date at the registered addresses of such Owners as
they  shall  appear as of the close of  business  on  such
Record  Date on the registration books maintained pursuant
to Section 2.09 hereof notwithstanding the cancellation of
any  such  Bond  upon  any  exchange  or  registration  of
transfer  subsequent to such Record Date, except  that  if
and  to  the extent that there should be a default on  the
payment  of interest on any Bond, such defaulted  interest
shall  be  paid to the Owners in whose name such Bond  (or
any Bond or Bonds issued upon any exchange or registration
of  transfer  thereof) is registered as of  the  close  of
business  on  a  date  selected  by  the  Trustee  in  its
discretion, but not more than 15 days or less than 10 days
prior  to  the date of payment of such defaulted interest;
notwithstanding the foregoing, except in respect of a Term
Rate Period and the Fixed Rate Period, upon request to the
Paying  Agent  by an Owner of not less than $1,000,000  in
aggregate  principal  amount of Bonds,  interest  on  such
Bonds and, after presentation and surrender of such Bonds,
the  principal thereof shall be paid to such Owner by wire
transfer  to the account maintained within the continental
United  States specified by such Owner or, if  such  Owner
maintains  an  account with the entity  acting  as  Paying
Agent, by deposit into such account.  Payment as aforesaid
shall  be  made  in such coin or currency  of  the  United
States  of America as, at the respective times of payment,
shall  be  legal  tender  for the payment  of  public  and
private debts.

   The Bonds and the form for registration of transfer and
the form of certificate of authentication to be printed on
the Bonds are to be in substantially the forms thereof set
forth  in  Exhibits A, B and C hereto, respectively,  with
necessary   or   appropriate  variations,  omissions   and
insertions  as  permitted or required by  this  Indenture.
Upon conversion to a Term Rate Period or to the Fixed Rate
Period,  a  new form of Bond may be prepared containing  a
summary of tender and redemption provisions applicable  to
the  Bonds  during  such Term Rate Period  or  Fixed  Rate
Period.

  II.14.        Execution of Bonds.  The  Bonds  shall  be
executed on behalf of the Pollution Control Corporation by
the President or a Vice President of the Pollution Control
Corporation   and   shall  have  affixed,   impressed   or
reproduced  thereon  the official seal  of  the  Pollution
Control  Corporation  which  shall  be  attested  by   the
Secretary  or  an  Assistant Secretary  of  the  Pollution
Control  Corporation.  Each of the foregoing officers  may
execute or cause to be executed with a facsimile signature
in  lieu  of his manual signature the Bonds, provided  the
signature  of either the President or a Vice President  of
the  Pollution  Control Corporation or  the  Secretary  or
Assistant  Secretary of the Pollution Control  Corporation
shall,   if  required  by  applicable  laws,  be  manually
subscribed.

     In   case  any  officer  of  the  Pollution   Control
Corporation  whose  signature  or  a  facsimile  of  whose
signature shall appear on the Bonds shall cease to be such
officer  before  the  authentication by  the  Trustee  and
delivery  of such Bonds, such signature or such  facsimile
shall  nevertheless  be  valid  and  sufficient  for   all
purposes,  the same as if he had remained in office  until
delivery;  and  any Bond may be signed on  behalf  of  the
Pollution Control Corporation by such persons as,  at  the
time  of  execution  of such Bond,  shall  be  the  proper
officers of the Pollution Control Corporation, even though
at  the date of such Bond or of the execution and delivery
of this Indenture any such person was not such officer.

  II.15.       Authentication of Bonds.  Only such Bonds as
shall    have   endorsed   thereon   a   certificate    of
authentication  substantially in the  form  set  forth  in
Exhibit  C  hereto duly executed by the Trustee  shall  be
entitled to any right or benefit under this Indenture.  No
Bond  shall be valid or obligatory for any purpose  unless
and  until  such certificate of authentication shall  have
been  duly  executed  by the Trustee,  and  such  executed
certificate of authentication of the Trustee upon any such
Bonds shall be conclusive evidence that such Bond has been
authenticated  and  delivered under this  Indenture.   The
Trustee's certificate of authentication on any Bond  shall
be  deemed to have been executed by it if signed  with  an
authorized signature of the Trustee, but it shall  not  be
necessary  that  the same person sign the  certificate  of
authentication on all of the Bonds issued hereunder.  This
Section 2.05 is subject to the provisions of Section 10.17
hereof.

  II.16.       Bonds Not General Obligations.  Neither the
County of Coconino, Arizona nor the State of Arizona shall
in any event be liable for the payment of the principal of
or  premium, if any, or interest on the Bonds, and neither
the  Bonds  nor  the  premium, if  any,  or  the  interest
thereon,  shall be construed to constitute an indebtedness
of  County  of Coconino, Arizona or the State  of  Arizona
within  the  meaning  of any constitutional  or  statutory
provisions whatsoever.  The Bonds and the premium, if any,
and  the interest thereon shall be limited obligations  of
the  Pollution Control Corporation payable solely from the
Receipts and Revenues of the Pollution Control Corporation
from  the  Loan  Agreement and the  other  moneys  pledged
therefor  under  this Indenture, and such  fact  shall  be
plainly  stated on the face of each Bond.   The  Pollution
Control  Corporation  shall not be obligated  to  pay  the
purchase price of Bonds from any source.

  II.17.        Prerequisites to Authentication of  Bonds.
The   Pollution  Control  Corporation  shall  execute  and
deliver  to the Trustee and the Trustee shall authenticate
the Bonds and deliver said Bonds to the initial purchasers
thereof  as  may be directed hereinafter in  this  Section
2.07.

    Prior  to  the  delivery on original issuance  by  the
Trustee of any authenticated Bonds there shall be or  have
been delivered to the Trustee:

     (a)   a duly certified copy of a resolution of the Board
  of   Directors  of  the  Pollution  Control  Corporation
  authorizing the execution and delivery of this Indenture
  and the Loan Agreement and the issuance of the Bonds;

     (b)   an original duly executed counterpart or a duly
  certified copy of the Loan Agreement;

     (c)   the Letter of Credit;

     (d)   a request and authorization to the Trustee on behalf
  of  the  Pollution Control Corporation,  signed  by  its
  President or a Vice President, to authenticate and deliver
  the Bonds in the aggregate principal amount determined by
  this  Indenture  to the purchaser or purchasers  therein
  identified  upon  payment to the Trustee,  but  for  the
  account of the Pollution Control Corporation, of  a  sum
  specified  in  such request and authorization  plus  any
  accrued  interest on such Bonds to the date of delivery;
  and

     (e)    a  written statement on behalf of the Company,
  executed  by  the President, any Vice President  or  the
  Treasurer, (i) approving the issuance and delivery of the
  Bonds and (ii) consenting to each and every provision of
  this Indenture.

  II.18.       Lost or Destroyed Bonds or Bonds Canceled in
Error.   If  any Bond, whether in temporary or  definitive
form,  is  lost (whether by reason of theft or otherwise),
destroyed (whether by mutilation, damage, in whole  or  in
part,  or  otherwise) or canceled in error, the  Pollution
Control  Corporation  may  execute  and  the  Trustee  may
authenticate a new Bond of like date and denomination  and
bearing   a   number  not  contemporaneously  outstanding;
provided that (a) in the case of any mutilated Bond,  such
mutilated  Bond shall first be surrendered to the  Trustee
and (b) in the case of any lost Bond or Bond destroyed  in
whole,  there  shall be first furnished to  the  Pollution
Control  Corporation, the Trustee and the Company evidence
of such loss or destruction.  In every case, the applicant
for  a substitute Bond shall furnish the Pollution Control
Corporation, the Trustee and the Company such security  or
indemnity as may be required by any of them.  In the event
any  lost  or destroyed Bond or a Bond canceled  in  error
shall  have  matured or is about to mature,  or  has  been
called  for  redemption, instead of issuing  a  substitute
Bond  the  Trustee may, in its discretion,  pay  the  same
without   surrender  thereof  if  there  shall  be   first
furnished  to  the  Pollution  Control  Corporation,   the
Trustee and the Company evidence of such loss, destruction
or  cancellation, together with indemnity, satisfactory to
them.   Upon  the  issuance of any  substitute  Bond,  the
Pollution Control Corporation and the Trustee may  require
the  payment of a sum sufficient to cover any tax or other
governmental  charge  that  may  be  imposed  in  relation
thereto.   The Trustee may charge the Owner  of  any  such
Bond  with  the Trustee's reasonable fees and expenses  in
connection with any transaction described in this  Section
2.08.

   Every substitute Bond issued pursuant to the provisions
of  this Section 2.08 by virtue of the fact that any  Bond
is  lost,  destroyed or canceled in error shall constitute
an  additional  contractual obligation  of  the  Pollution
Control  Corporation, whether or not  the  Bond  so  lost,
destroyed  or  canceled shall be at any time  enforceable,
and  shall  be  entitled  to  all  the  benefits  of  this
Indenture  equally and proportionately with  any  and  all
other  Bonds  duly issued hereunder.  All Bonds  shall  be
held  and  owned upon the express condition that,  to  the
extent  permitted  by  law, the foregoing  provisions  are
exclusive  with respect to the replacement or  payment  of
lost,    destroyed    or   improperly   canceled    Bonds,
notwithstanding  any  law  or  statute  now  existing   or
hereafter enacted.

  II.19.       Transfer, Registration and Exchange of Bonds.
The  Registrar  shall maintain and keep, at its  Principal
Office,  books  for the registration and  registration  of
transfer  of Bonds, which, at all reasonable times,  shall
be   open   for   inspection  by  the  Pollution   Control
Corporation,  the  Trustee  and  the  Company;  and,  upon
presentation  for  such purpose of any  Bond  entitled  to
registration or registration of transfer at the  Principal
Office  of the Registrar, the Registrar shall register  or
register   the  transfer  in  such  books,    under   such
reasonable  regulations  as the Registrar  may  prescribe.
The  Registrar  shall  make all  necessary  provisions  to
permit  the exchange or registration of transfer of  Bonds
at its Principal Office.

    The transfer of any Bond shall be registered upon  the
registration books of the Registrar at the written request
of  the  Owner thereof or his attorney duly authorized  in
writing, upon surrender thereof at the Principal Office of
the  Registrar,  together  with a  written  instrument  of
transfer  satisfactory to the Registrar duly  executed  by
the  Owner  or  his  duly authorized attorney.   Upon  the
registration  of transfer of any such Bond or  Bonds,  the
Pollution Control Corporation shall issue in the  name  of
the transferee, in authorized denominations, a new Bond or
Bonds  in  the  same  aggregate principal  amount  as  the
surrendered Bond or Bonds.

    The  Pollution Control Corporation, the  Trustee,  the
Tender  Agent, the Paying Agent, any Co-Paying Agent,  the
Registrar and the Remarketing Agent may deem and treat the
Owner  of  any  Bond as the absolute owner of  such  Bond,
whether such Bond shall be overdue or not, for the purpose
of  receiving payment of, or on account of, the  principal
of and premium, if any, and, except as provided in Section
2.03  hereof, interest on, or the purchase price of,  such
Bond and for all other purposes, and neither the Pollution
Control  Corporation, the Trustee, the Tender  Agent,  the
Paying  Agent, any Co-Paying Agent, the Registrar nor  the
Remarketing Agent shall be affected by any notice  to  the
contrary.  All such payments so made to any such Owner  or
upon his order shall be valid and effective to satisfy and
discharge  the liability upon such Bond to the  extent  of
the sum or sums so paid.

    Bonds, upon surrender thereof at the Principal  Office
of  the Registrar may, at the option of the Owner thereof,
be  exchanged for an equal aggregate principal  amount  of
Bonds of any authorized denomination.

   In all cases in which the privilege of exchanging Bonds
or  registering  the transfer of Bonds is  exercised,  the
Pollution  Control  Corporation  shall  execute  and   the
Trustee shall authenticate and deliver Bonds in accordance
with  the  provisions of this Indenture.  For  every  such
exchange  or  registration of transfer of  Bonds,  whether
temporary    or   definitive,   the   Pollution    Control
Corporation,  the  Registrar, or the Trustee  may  make  a
charge  sufficient to reimburse it for any  tax  or  other
governmental  charge required to be paid with  respect  to
such  exchange or registration of transfer, which  sum  or
sums  shall be paid by the person requesting such exchange
or  registration of transfer as a condition  precedent  to
the  exercise of the privilege of making such exchange  or
registration of transfer.  Except in connection  with  the
tender  of Bonds for purchase pursuant to their terms  and
the delivery thereof pursuant to Section 13.07 hereof, the
Registrar  shall  not be obligated (a) to  make  any  such
exchange  or registration of transfer of Bonds during  the
fifteen (15) days next preceding the date on which  notice
of  any proposed redemption of Bonds is given, (b) to make
any  exchange  or registration of transfer  of  any  Bonds
called  for redemption or (c) in the case of Bonds bearing
interest  at a Term Rate or the Fixed Rate, in the  period
following  the  Record  Date and  prior  to  the  Interest
Payment Date to which such Record Date relates.

   The Bonds are to be initially registered in the name of
Cede  &  Co., as nominee for the Depositary.   Such  Bonds
shall  not be transferable or exchangeable, nor shall  any
purported transfer be registered, except as follows:

     (a)    such  Bonds may be transferred in  whole,  and
  appropriate registration of transfer effected,  if  such
  transfer is by such nominee to the Depositary, or by the
  Depositary to another nominee thereof, or by any nominee
  of the Depositary to any other nominee thereof, or by the
  Depositary  or  any  nominee thereof  to  any  successor
  securities depositary or any nominee thereof; and

     (b)   such Bond may be exchanged for definitive Bonds
  registered  in  the respective names of  the  beneficial
  holders  thereof, and thereafter shall  be  transferable
  without restriction, if:

     (i)    the Depositary shall have notified the Company and
  the Trustee that it is unwilling or unable to continue to
  act  as securities depositary with respect to such Bonds
  and  the  Trustee  shall not have been notified  by  the
  Company  within ninety (90) days of the  identity  of  a
  successor  securities depositary with  respect  to  such
  Bonds;

     (ii)   the Company shall have delivered to the Trustee a
  written instrument to the effect that such Bonds shall be
  so exchangeable on an after a date specified therein; or

     (iii)       (1) an Event of Default shall have occurred
  and be continuing, (2) the Trustee shall have given notice
  of such Event of Default pursuant to Section 10.19 hereof
  and (3) there shall have been delivered to the Pollution
  Control  Corporation, the Company  and  the  Trustee  an
  opinion of counsel to the effect that the interests of the
  beneficial owners of such Bonds in respect thereof will be
  materially impaired unless such owners become owners  of
  definitive Bonds.

    The  Bonds delivered to the Depositary may  contain  a
legend   reflecting   the   foregoing   restrictions    on
registration of transfer and exchange.

  II.2  0.  Notice of Mandatory Tender; Special Notice  by
Tender Agent During Flexible Rate Period.  (a)  The Tender
Agent shall give notice to the Owners of the Bonds of each
event  which  requires the mandatory tender of  the  Bonds
pursuant to Section 2.02(h), other than the occurrence  of
a  last day of a Flexible  Rate Period which shall not  be
the  effective date of a new Rate Period and other than  a
mandatory   tender  for  purchase  pursuant   to   Section
2.02(h)(iv).  Such notice shall be given in the manner and
at  the  times  set forth in Section 3.03 hereof  for  the
giving  of  a  notice of redemption.   Such  notice  shall
describe the event which requires the Bonds to be tendered
and,  if such event shall be the Termination or Expiration
of   a  Security  Arrangement,  shall  also  contain   the
information referred to in Section 4.08(c) hereof.  Notice
of  a  mandatory tender for purchase pursuant  to  Section
2.02(h)(iv) shall be given by the Tender Agent as soon  as
practicable  by Mail upon receipt by the Tender  Agent  of
the   notice   from  the  Trustee  specified  in   Section
2.02(h)(iv) to all Owners of Outstanding Bonds.

  (a)     Upon  each registration of transfer  of  a  Bond
bearing  interest  at a Flexible Rate, the  Tender   Agent
shall  give written notice to the transferee that  (i)  no
notices of the length of any Flexible Rate Period  or  the
Flexible Rate borne by his Bond during such period will be
given  to the Owner of the Bond, but that such information
may  be obtained, upon request, from the Remarketing Agent
and setting forth the manner that such information may  be
obtained, (ii) the Owner of any Bond bearing interest at a
Flexible Rate will be required to tender such Bond on  its
Interest  Payment Date and (iii) no additional  notice  of
any such requirement to tender will be given to the Owner.

  II.22.        Other Obligations.  The Pollution  Control
Corporation expressly reserves the right to issue, to  the
extent  permitted by law, but shall not  be  obligated  to
issue,  obligations under another indenture or  indentures
to   provide   additional  funds  to  pay  the   Cost   of
Construction  of the Facilities or to refund  all  or  any
principal amount of the Bonds, or any combination thereof.

  II.23.       Temporary Bonds.  Pending the preparation of
definitive  Bonds, the Pollution Control  Corporation  may
execute  and  the Trustee shall authenticate  and  deliver
temporary  Bonds.  Temporary Bonds shall  be  issuable  as
registered   Bonds  without  coupons,  of  any  authorized
denomination,  and  substantially  in  the  form  of   the
definitive  Bonds but with such omissions, insertions  and
variations as may be appropriate for temporary Bonds,  all
as may be determined by the Pollution Control Corporation.
Temporary  Bonds  may  contain  such  reference   to   any
provisions of this Indenture as may be appropriate.  Every
temporary Bond shall be executed by the Pollution  Control
Corporation and be authenticated by the Trustee  upon  the
same conditions and in substantially the same manner,  and
with like effect, as the definitive Bonds.  As promptly as
practicable   the  Pollution  Control  Corporation   shall
execute  and shall furnish definitive Bonds and  thereupon
temporary  Bonds  may be surrendered in exchange  therefor
without charge at the Principal Office of the Trustee, and
the Trustee shall authenticate and deliver in exchange for
such temporary Bonds a like aggregate principal amount  of
definitive  Bonds of authorized denominations.   Until  so
exchanged  the  temporary Bonds shall be entitled  to  the
same benefits under this Indenture as definitive Bonds.

  II.24.       Cancellation of Bonds.  All Bonds which shall
have been surrendered to the Paying Agent or any Co-Paying
Agent for payment or redemption, and all Bonds which shall
have  been  surrendered to the Registrar for  exchange  or
registration  of  transfer,  shall  be  delivered  to  the
Trustee  for  cancellation.  All  Bonds  delivered  to  or
acquired by the Trustee for cancellation shall be canceled
and  destroyed by the Trustee.  The Trustee shall  furnish
to  the  Pollution Control Corporation, the Paying  Agent,
the Registrar and the Company counterparts of certificates
evidencing   such   cancellation   and   destruction   and
specifying such Bonds by number.

  II.25.       Payment of Principal and Interest.  For the
payment  of  interest on the Bonds, the Pollution  Control
Corporation shall cause to be deposited in the Bond  Fund,
on  each Interest Payment Date, solely out of the Receipts
and Revenues of the Pollution Control Corporation from the
Loan  Agreement  and  other moneys  pledged  therefor,  an
amount  sufficient to pay the interest to  become  due  on
such  Interest  Payment  Date.   The  obligation  of   the
Pollution Control Corporation to cause any such deposit to
be made hereunder shall be reduced by the amount of moneys
in  the Bond Fund available on such Interest Payment  Date
for the payment of interest on the Bonds.

    For  the  payment of the principal of the  Bonds  upon
maturity, the Pollution Control Corporation shall cause to
be   deposited  in  the  Bond  Fund,  on  the  stated   or
accelerated  date of maturity, solely out of the  Receipts
and Revenues of the Pollution Control Corporation from the
Loan  Agreement  and  other moneys  pledged  therefor,  an
amount sufficient to pay the principal of the Bonds.   The
obligation of the Pollution Control Corporation  to  cause
any such deposit to be made hereunder shall be reduced  by
the  amount  of moneys in the Bond Fund available  on  the
maturity  date  for the payment of the  principal  of  the
Bonds.


III                REDEMPTION OF BONDS

  III.11.      Redemption Provisions.  (a) When interest on
the  Bonds is payable at Flexible Rates or a Variable Rate
other  than  a  Term Rate, the Bonds shall be  subject  to
redemption  by the Pollution Control Corporation,  at  the
direction of the Company, in whole at any time or in  part
from  time  to time, at the principal amount thereof  plus
accrued interest to the redemption date.

  (a)     When interest on the Bonds is payable at a  Term
Rate  or  the  Fixed Rate, the Bonds shall be  subject  to
redemption  by the Pollution Control Corporation,  at  the
direction  of  the Company, in whole at any  time  at  the
principal  amount  thereof plus accrued  interest  to  the
redemption date, if:

     (i)     the  Company shall have determined  that  the
  continued  operation  of  the  Plant  is  impracticable,
  uneconomical or undesirable for any reason;

     (ii)    the  Company shall have determined  that  the
  continued  operation of the Facilities is impracticable,
  uneconomical or undesirable due to (A) the imposition of
  taxes, other than ad valorem taxes currently levied upon
  privately owned property used for the same general purpose
  as  the Facilities, or other liabilities or burdens with
  respect  to  the  Facilities or operation  thereof,  (B)
  changes in technology, in environmental standards or legal
  requirements or in the economic availability of materials,
  supplies,  equipment or labor or (C) destruction  of  or
  damage to all or part of the Facilities;

     (iii)       all or substantially all of the Facilities or
  the  Plant shall have been condemned or taken by eminent
  domain; or

     (iv)   the operation of the Facilities or the Plant shall
  have been enjoined or shall have otherwise been prohibited
  by,  or shall conflict with, any order, decree, rule  or
  regulation of any court or of any federal, state or local
  regulatory   body,  administrative   agency   or   other
  governmental body.

  (b)     When interest on the Bonds is payable at a  Term
Rate  for a Term Rate Period of five years or more or  the
Fixed  Rate,  the Bonds shall be subject to redemption  by
the Pollution Control Corporation, at the direction of the
Company,  on any day in whole at any time or in part  from
time  to  time, at the applicable redemption  price  shown

     Anything   in   this  Indenture   to   the   contrary
notwithstanding,  in  the event  that  the  Company  shall
consolidate with, merge with or into, or sell or otherwise
transfer  all  or  substantially all  of  its  assets  to,
another corporation in accordance with Section 6.01 of the
Loan  Agreement, the Bonds shall be subject to  redemption
by  the Pollution Control Corporation, at the direction of
the Company, in whole, at any time prior to the first date
on  which  the  Bonds  are  redeemable  as  herein  before
provided  in  paragraph (c) at the redemption price  which
would be applicable on such date plus accrued interest  to
the redemption date.

  (c)    The Bonds shall be subject to mandatory redemption
by  the  Pollution Control Corporation, at  the  principal
amount  thereof  plus accrued interest to  the  redemption
date,  on  the 180th day (or such earlier date as  may  be
designated by the Company) after a final determination  by
a  court  of  competent jurisdiction or an  administrative
agency,  to  the effect that, as a result of a failure  by
the  Company to perform or observe any covenant, agreement
or  representation  contained in the Loan  Agreement,  the
interest  payable  on  the Bonds is included  for  federal
income  tax  purposes in the gross income  of  the  owners
thereof,  other  than  any  owner  of  a  Bond  who  is  a
"substantial user" of the Facilities or a "related person"
within the meaning of Section 103(b)(13) of the 1954 Code.
No  determination  by  any court or administrative  agency
shall be considered final for the purposes of this Section
3.01  (d) unless the Company shall have been given  timely
notice   of   the  proceeding  which  resulted   in   such
determination  and an opportunity to participate  in  such
proceeding, either directly or through an owner of a Bond,
and until the conclusion of any appellate review sought by
any party to such proceeding or the expiration of the time
for  seeking  such  review. The Bonds  shall  be  redeemed
either  in whole or in part in such principal amount  that
the  interest  payable on the Bonds remaining  outstanding
after  such redemption would not be included in the  gross
income of any owner thereof, other than an owner of a Bond
who  is  a  "substantial  user" of  the  Facilities  or  a
"related  person" within the meaning of Section 103(b)(13)
of the 1954 Code.

  (d)     In  the event that the aggregate of the  amounts
deposited pursuant to Section 5.02 hereof into the Capital
Account  and the Investment Account maintained within  the
Bond Fund, together with any income or other gain from the
investment  thereof, shall at any time, or  from  time  to
time,  be equal to or greater than $100,000, but  only  to
the  extent  that such amounts are required under  Section
4.04(b)  hereof to be applied to the redemption of  Bonds,
the  Pollution Control Corporation shall redeem Bonds,  at
the  principal amount thereof plus accrued interest to the
redemption date, in the largest aggregate principal amount
which  does  not  exceed the amount  of  such  deposit  or
deposits, together with such income or gain, on  the  next
Interest Payment Date on which a redemption may be made in
accordance with the provisions of Section 3.03(a), (b)  or
(c)  hereof  and  on  which Bonds,  in  such  amount,  are
otherwise redeemable at the principal amount thereof under
subsection (a), (b) or (c) of this Section 3.01.

  (e)    The Bonds shall be subject to mandatory redemption
by  the  Pollution Control Corporation, at  the  principal
amount  thereof  plus accrued interest to  the  redemption
date,  upon  the  occurrence of either  of  the  following
events:

  (i)   receipt by the Trustee, following a drawing  on  a
  Security Arrangement on which the Company shall  not  be
  the  obligor to pay accrued interest, or the portion  of
  purchase price equal to accrued interest, on the  Bonds,
  of  notice from the Bank that the amount available to be
  drawn   on  such  Security  Arrangement  will   not   be
  reinstated  (in  respect  of  interest  or  portion   of
  purchase price equal to accrued interest) in the  amount
  of  such  drawing and directing the Trustee  to  provide
  notice  to  the  Pollution Control  Corporation  of  its
  resulting obligation to redeem the Bonds; or

  (ii)   receipt  by the Trustee of notice from  the  Bank
  stating   that   an   Event   of   Default   under   the
  Reimbursement Agreement (or other agreement between  the
  Company  and the Bank pursuant to which the Bank  issued
  and  delivered  to  the Trustee a Security  Arrangement)
  has   occurred  and  is  continuing  and  directing  the
  Trustee  to  provide  notice to  the  Pollution  Control
  Corporation  of its resulting obligation to  redeem  the
  Bonds.

    Upon  the occurrence of either of the events described
in  the  immediately  preceding paragraph,  the  Pollution
Control Corporation shall be obligated to redeem the Bonds
on  the  first Business Day after the occurrence  of  such
event  on which the Trustee may make a drawing or drawings
on  a Security Arrangement on which the Company shall  not
be  the  obligor and on which the proceeds of such drawing
or  drawings shall be available, but shall not redeem  the
Bonds  prior to such date.  The Trustee shall give written
notice  of  such  obligation to redeem the  Bonds  to  the
Pollution Control Corporation, the Company, the Bank,  the
Tender  Agent  and the Remarketing Agent  and  shall  give
notice thereof as soon as practicable by Mail upon receipt
by   the  Trustee  of  the  notice  specified  in  Section
3.01(f)(i) or (ii) to all Owners of Outstanding Bonds.

    The  provisions of the second preceding paragraph  are
subject  to  the condition that if either  of  the  events
described  in  clause (i) or (ii) of the second  preceding
paragraph  shall  have occurred and if the  Trustee  shall
thereafter have received notice from the Bank (a) that the
notice  which requires a mandatory redemption pursuant  to
the  second preceding paragraph has been withdrawn and (b)
that  the  amounts available to be drawn on  the  Security
Arrangement to pay (i) the principal of the Bonds  or  the
portion  of  purchase price equal to  principal  and  (ii)
interest  on  the Bonds and the portion of purchase  price
equal  to accrued interest have been reinstated, then,  in
every  such case, the event giving rise to such  mandatory
redemption   shall  be  deemed  to  be  waived   and   all
proceedings  for  such redemption shall be  rescinded  and
annulled,  and  the  Trustee shall promptly  give  written
notice  of  such waiver, rescission and annulment  to  the
Pollution Control Corporation, the Company, the Bank,  the
Tender Agent and the Remarketing Agent, and, if notice  of
such redemption shall have been given to the Owners of the
Bonds, shall give notice thereof by Mail to all Owners  of
Outstanding  Bonds;  but  no such waiver,  rescission  and
annulment  shall extend to or affect any subsequent  event
requiring  a mandatory redemption or impair any  right  or
remedy consequent thereon.

  III.12.       Selection  of Bonds  to  be  Redeemed.   A
redemption of Bonds shall be a redemption of the whole  or
of any part of the Bonds from any funds available for that
purpose.   If less than all the Bonds shall be called  for
redemption   under   any  provision  of   this   Indenture
permitting  such partial redemption, the particular  Bonds
or  portions of Bonds to be redeemed shall be selected  by
the  Trustee,  in  such  manner  as  the  Trustee  in  its
discretion  may  deem  proper, in the aggregate  principal
amount  designated  to  the  Trustee  by  the  Company  or
otherwise   as  required  by  this  Indenture;   provided,
however,  that  if,  as indicated in a certificate  of  an
Authorized   Company  Representative  delivered   to   the
Trustee,  the  Company shall have offered to purchase  all
Bonds  then Outstanding and less than all such Bonds  have
been  tendered  to  the  Company for  such  purchase,  the
Trustee,  at  the  direction  of  an  Authorized   Company
Representative, shall select for redemption all such Bonds
which  shall  not  have  been so  tendered  and  provided,
further, that, if the redemption date shall not be  during
a Flexible Rate Period, Term Rate Period or the Fixed Rate
Period, the portion of any Bond to be redeemed shall be in
the principal amount of $100,000 or some integral multiple
thereof  and that, in selecting Bonds for redemption,  the
Trustee shall treat each Bond as representing that  number
of  Bonds  which  is  obtained by dividing  the  principal
amount  of  such Bond by $100,000; and provided,  further,
that,  if  the redemption date shall be during a  Flexible
Rate  Period, a Term Rate Period or the Fixed Rate Period,
the  portion of any Bond to be redeemed shall  be  in  the
principal  amount  of  $5,000 or  some  integral  multiple
thereof (and, in the case of a Flexible Rate Period, in  a
minimum  principal  amount  of  $100,000)  and  that,   in
selecting  Bonds for redemption, the Trustee  shall  treat
each  Bond as representing that number of Bonds  which  is
obtained by dividing the principal amount of such Bond  by
$5,000. For any redemption not occurring during a Flexible
Rate Period, Term Rate Period or the Fixed Rate Period, if
it  is  determined that one or more, but not all,  of  the
$100,000 units of principal amount represented by any such
Bond is to be called for redemption, then, upon notice  of
intention to redeem such $100,000 unit or units the  Owner
of  such Bond shall forthwith surrender such Bond  to  the
Paying  Agent  or any Co-Paying Agent for (a)  payment  to
such Owner of the redemption price of the $100,000 unit or
units  of principal amount called for redemption  and  (b)
delivery  to  such Owner of a new Bond  or  Bonds  in  the
aggregate  principal amount of the unredeemed  balance  of
the  principal  amount of such Bond.  For  any  redemption
occurring  during  a  Flexible Rate Period,  a  Term  Rate
Period or the Fixed Rate Period, if it is determined  that
one or more, but not all, of the $5,000 units of principal
amount  represented by any such Bond is to be  called  for
redemption, then, upon notice of intention to redeem  such
$5,000  unit  or  units,  the Owner  of  such  Bond  shall
forthwith surrender such Bond to the Paying Agent  or  any
Co-Paying  Agent  for (y) payment to  such  Owner  of  the
redemption  price  (including the redemption  premium,  if
any,   and   accrued  interest  to  the  date  fixed   for
redemption)  of  the  $5,000 unit or  units  of  principal
amount  called  for redemption and (z)  delivery  to  such
Owner  of  a new Bond or Bonds in the aggregate  principal
amount  of the unredeemed balance of the principal  amount
of  any  such  Bond.   Bonds representing  the  unredeemed
balance of the principal amount of any such Bond shall  be
delivered  to the Owner thereof, without charge  therefor.
In  selecting Bonds for redemption, the Trustee may  shall
first  select Bonds tendered for purchase pursuant to  the
terms   thereof   and  delivered,  and   then   held,   as
contemplated  in  Section 13.07(c)  hereof  and  (ii)  the
Trustee   may  treat  Bonds  so  tendered  and   otherwise
delivered  pursuant  to Section 13.07  hereof  during  the
fifteen  (15)  days next preceding the  first  mailing  of
notice of any proposed redemption of Bonds as though  such
tender  and delivery had not occurred.  If a Bond selected
for  redemption shall have been tendered pursuant  to  the
terms  thereof  and delivered pursuant  to  Section  13.07
hereof on or after the fifteenth (15th) day next preceding
the first mailing of notice of any proposed redemption  of
Bonds,  then  the  Bond so delivered pursuant  to  Section
13.07  hereof shall be deemed to be the Bond  so  tendered
and  selected for redemption.  If the Owner  of  any  such
Bond  of  a  denomination greater  than  $100,000  ($5,000
during a Term Rate Period or the Fixed Rate Period)  shall
fail  to  present  such Bond to the Paying  Agent  or  any
Co-Paying  Agent  for payment and exchange  as  aforesaid,
such  Bond shall, nevertheless, become due and payable  on
the  date  fixed  for  redemption to  the  extent  of  the
$100,000  ($5,000 during a Term Rate Period or  the  Fixed
Rate Period) unit or units of principal amount called  for
redemption (and to that extent only).

  III.13.      Procedure for Redemption.  (a) In the event
any  of  the Bonds are called for redemption, the  Trustee
shall  give  notice, in the name of the Pollution  Control
Corporation, of the redemption of such Bonds, which notice
shall (i) specify the Bonds to be redeemed, the redemption
date,  the redemption price, and the place or places where
amounts  due  upon such redemption will be payable  (which
shall  be the Principal Office of the Paying Agent or  any
Co-Paying Agent) and, if less than all of the Bonds are to
be  redeemed, the numbers of the Bonds to be redeemed, and
the  portion  of the principal amount of any  Bond  to  be
redeemed  in  part,  (ii)  state  any  condition  to  such
redemption  and  (iii) state that on the redemption  date,
and upon the satisfaction of any such condition, the Bonds
or  portions  thereof to be redeemed shall cease  to  bear
interest.   Such  notice  may  set  forth  any  additional
information  relating  to  such redemption.   Such  notice
shall  be  given by Mail at least thirty (30)  days  prior
(except  in  the case of a redemption pursuant to  Section
3.01(f)) to the date fixed for redemption to the Owners of
the  Bonds to be redeemed; provided, however, that failure
duly  to  give such Notice by Mail, or any defect therein,
shall  not affect the validity of any proceedings for  the
redemption of Bonds as to which there shall have  been  no
such  failure  or defect; and provided, further,  that  if
such Notice by Mail shall not have been given with respect
to a Bond delivered pursuant to Section 13.07 hereof on or
after  the  fifteenth (15th) day next preceding the  first
mailing of notice of any proposed redemption of Bonds, and
if  such  Bond  shall be deemed to have been selected  for
redemption  pursuant to Section 3.02 hereof,  such  notice
shall  be  attached  to such Bond prior  to  the  delivery
thereof pursuant to Section 13.07 hereof.  If a notice  of
redemption shall be unconditional, or if the conditions of
a   conditional  notice  or  redemption  shall  have  been
satisfied, then upon presentation and surrender  of  Bonds
so  called  for  redemption at  the  place  or  places  of
payment, such Bonds shall be redeemed.  The Trustee  shall
promptly  deliver to the Company and the Bank  a  copy  of
each such notice of redemption.

  (a)     With  respect to any notice of  an  event  which
requires the Owners of the Bonds to tender their Bonds  in
accordance  with Section 2.02(h)(iii) hereof, such  notice
shall  contain  the  information referred  to  in  Section
4.08(c) hereof.

  (b)   With respect to any notice of redemption of Bonds in
accordance with subsection (a), (b) or (c) of Section 3.01
hereof, unless, upon the giving of such notice, such Bonds
shall  be  deemed to have been paid within the meaning  of
Article  VIII  hereof, such notice shall state  that  such
redemption shall be conditional upon the receipt,  by  the
Trustee at or prior to the opening of business on the date
fixed for such redemption, of moneys sufficient to pay the
principal  of  and premium, if any, and interest  on  such
Bonds  to  be redeemed, and that if such moneys shall  not
have been so received said notice shall be of no force and
effect and the Pollution Control Corporation shall not  be
required  to  redeem such Bonds.  In the event  that  such
notice  of redemption contains such a condition  and  such
moneys  are not so received, the redemption shall  not  be
made  and  the  Trustee  shall within  a  reasonable  time
thereafter give notice, in the manner in which the  notice
of  redemption  was given, that such moneys  were  not  so
received.

  (c)     Any Bonds and portions of Bonds which have  been
duly  selected for redemption and which are deemed  to  be
paid in accordance with Article VIII hereof shall cease to
bear interest on the specified redemption date.

  (d)    The Trustee shall not give any notice of redemption
to  be made in accordance with Section 3.01(c) hereof when
a  Security  Arrangement shall be in effect on  which  the
Company  shall  not be the obligor unless,  prior  to  the
giving   of   such  notice,  either  (i)   such   Security
Arrangement shall expressly allow a drawing thereunder for
the purpose of paying, and in an amount sufficient to pay,
any  redemption  premium payable upon such redemption,  or
(ii) there shall be on deposit in the Bond Fund moneys  in
an  amount  sufficient to pay such premium and  which  are
Available Moneys.

  III.14.        No  Partial  Redemption  After   Default.
Anything    in    this   Indenture   to    the    contrary
notwithstanding,  if  there shall  have  occurred  and  be
continuing an Event of Default defined in clause (a),  (b)
or  (c)  of  the first paragraph of Section  9.01  hereof,
there shall be no redemption of less than all of the Bonds
at the time Outstanding.

  III.15.       Payment  of  Redemption  Price.   For  the
redemption  of  any  of the Bonds, the  Pollution  Control
Corporation shall cause to be deposited in the Bond  Fund,
on  the  redemption date, solely out of the  Receipts  and
Revenues  of  the Pollution Control Corporation  from  the
Loan  Agreement, an amount sufficient to pay the principal
of and premium, if any, and interest to become due on such
redemption date.  The obligation of the Pollution  Control
Corporation to cause any such deposit to be made hereunder
shall be reduced by the amount of moneys in the Bond  Fund
available  on  such  redemption date for  payment  of  the
principal of and premium, if any, and accrued interest  on
the Bonds to be redeemed.


IV                    THE BOND FUND

  IV.11.        Creation  of Bond Fund.  There  is  hereby
created  and established with the Trustee a trust fund  in
the  name  of  the  Pollution Control  Corporation  to  be
designated  "Coconino  County, Arizona  Pollution  Control
Corporation Pollution Control Revenue Bonds, 1996 Series A
(Tucson  Electric Power Company Project) Bond Fund".   The
Trustee  shall  establish  and  maintain  such  segregated
subaccounts as shall be necessary to comply with the order
of priority for payments on the Bonds set forth in Section
4.04(a)  hereof  and  such other  subaccounts  as  may  be
requested  by  an Authorized Company Representative.   The
Bond  Fund,  and  all  moneys and certificated  securities
therein, shall be kept in the possession of the Trustee.

  IV.12.        Liens.  The Pollution Control  Corporation
shall  not create any lien upon the Bond Fund or upon  the
Receipts and Revenues of the Pollution Control Corporation
from  the  Loan  Agreement  other  than  the  lien  hereby
created.

  IV.13.       Deposits into Bond Fund.  (a) There shall be
deposited into the Bond Fund:

  purchasers thereof, such accrued interest to be deposited

  Fund by Section 5.02 hereof, such amounts to be deposited
  into the Capital Account or the Investment Account;

  to be deposited into the General Account;

     (iv)  all Loan Payments, and all moneys drawn by or made
  available  to the Trustee under any Security Arrangement
  for the payment of principal of and premium, if any, and
  interest  on the Bonds, such payments and moneys  to  be
  deposited into the General Account;

     (v)   all amounts required to be deposited into the Bond
  Fund  by  Section 13.01(c) hereof, such  amounts  to  be
  deposited into the General Account; and

     (vi)  all other moneys received by the Trustee under and
  pursuant  to any provision of the Loan Agreement,  other
  than  Sections 5.03, 5.04 and 8.05 thereof, or from  any
  other source when accompanied by directions by the Company
  that such moneys are to be paid into the Bond Fund, such
  moneys to be deposited into the account specified by such
  provision of the Loan Agreement or by such directions, or,
  if no specification is made, into the General Account.

  (b)    All  income or other gain from the investment  of
moneys  in  the Capital Account or the Investment  Account
shall  be  deposited  into  the Investment  Account.   All
income or other gain from the investment of moneys in  the
General  Account  shall  be  deposited  into  the  General
Account.

  IV.14.       Use of Moneys in Bond Fund.  (a) Except  as
otherwise provided in subsection (d) of this Section  4.04
and in Sections 4.06, 9.01 and 10.04 hereof, moneys in the
Bond  Fund constituting part of the Trust Estate shall  be
used  solely  for  the  payment of the  principal  of  and
premium,  if  any, and interest on the Bonds as  the  same
shall  become due and payable at maturity, upon redemption
or otherwise.  Funds for such payments of the principal of
and  premium, if any, and interest on the Bonds  shall  be
derived  from  the  following  sources  in  the  order  of
priority indicated:

     (i)   moneys, if any, paid into the Bond Fund pursuant to
  clause  (i)  of  Section 4.03(a) hereof which  shall  be
  applied to the payment of interest on the Bonds;

     (ii)   moneys furnished by the Company to the Trustee
  pursuant  to  Section  9.01 of the Loan  Agreement,  and
  proceeds  from the investment thereof, which  constitute
  Available Moneys;

     (iii)      moneys drawn by, or made available to, the
  Trustee under any Security Arrangement for the payment of
  the principal of and premium, if any, and interest on the
  Bonds;

     (iv)  amounts deposited into the Bond Fund pursuant to
  clause (ii) or (iii) of Section 4.03(a) hereof; and

     (v)   Loan Payments or moneys furnished by the Company to
  the Trustee pursuant to Section 9.01 of the Loan Agreement
  or moneys deposited into the Bond Fund pursuant to Section
  13.01 hereof.

  (b)    Moneys deposited pursuant to Section 5.02  hereof
into   the  Capital  Account  or  the  Investment  Account
maintained within the Bond Fund, and any income  or  other
gain from the investment thereof, shall be applied by  the
Trustee  (i)  in whole or in part (A) to the  purchase  of
Bonds  in such amounts, at such prices, at such times  and
otherwise   as   directed   by   an   Authorized   Company
Representative,  excluding the purchase of  Bonds  by  the
Tender  Agent pursuant to Section 13.03 hereof, or to  the
redemption,  at  the direction of the  Company,  of  Bonds
pursuant  to subsection (a) or (c) or, if applicable,  (b)
of Section 3.01 hereof or (B) in any other manner directed
by   an   Authorized  Company  Representative  which,   as
indicated in an opinion of Bond Counsel furnished  by  the
Company  to  the  Pollution Control  Corporation  and  the
Trustee,  will not, in and of itself, impair the  validity
under  the  Act  of  the  Bonds or the  exclusion  of  the
interest on the Bonds from gross income for federal income
tax  purposes,  or, in the absence of any  such  purchase,
redemption  or  direction on or prior to  the  forty-fifth
(45th)  day  prior  to  the first  Interest  Payment  Date
specified  in Section 3.01(e) hereof, (ii) to the  payment
of  principal upon the redemption, from time to  time,  of
Bonds pursuant to Section 3.01(e) hereof, any moneys which
are  not  so  applied to be retained in the accounts  into
which  they  were deposited and applied by the Trustee  to
the  payment  of principal of Bonds either at maturity  or
upon  the  redemption of all or any portion of the  Bonds,
whichever occurs first.  Pending the application of moneys
deposited  into  the Bond Fund pursuant  to  Section  5.02
hereof,   such  moneys  may  be  invested  in   Investment
Securities in the manner permitted by Section 6.01 hereof,
provided  that such investment shall not produce  a  yield
greater  than the yield on the Bonds unless, as  indicated
in  an opinion of Bond Counsel furnished by the Company to
the   Pollution  Control  Corporation  and  the   Trustee,
investments producing a greater yield would not, in and of
itself, impair the exclusion from gross income for federal
income tax purposes of the interest on the Bonds.  In  the
case   of   any  such  redemption  made  when  a  Security
Arrangement  is  in effect, if moneys for such  redemption
shall  have  been  drawn  by, or made  available  to,  the
Trustee under such Security Arrangement, the Trustee shall
reimburse the obligor on such Security Arrangement for the
amount  so  drawn  by, or made available to,  the  Trustee
with,  and to the extent of, any moneys deposited pursuant
to  Section  5.02 hereof into the Bond Fund and  otherwise
available therefor.

  (c)    In  the event that all of the Bonds cease  to  be
Outstanding,  any moneys remaining in the Capital  Account
or  the  Investment  Account shall be deposited  into  the
General Account.

    (d)  Upon  receipt by the Trustee from the Bank  of  a
notice  stating that the Bank has not been reimbursed  for
any  drawing  or  drawings  on the  Letter  of  Credit  as
contemplated in Section 4.08(a) hereof, the Trustee  shall
promptly pay to the Bank from moneys in the Bond  Fund  an
amount equal to the lesser of (i) the total amount owed by
the  Company  to  the Bank in respect of such  drawing  or
drawings  as specified in such notice and (ii)  the  total
amount  on deposit in all accounts and subaccounts  within
the Bond Fund; provided, however, that there shall not  be
taken  into account for purposes of clause (ii) above  (x)
moneys   described  in  clause  (i),  (ii)  or  (iii)   in
subsection  (a) of this Section, (y) any moneys  furnished
by  the Company to the Trustee pursuant to Section 9.01 of
the  Loan Agreement or moneys furnished by the Company  to
the  Tender  Agent pursuant to Section 10.01 of  the  Loan
Agreement  and subsequently deposited into the  Bond  Fund
pursuant  to  Section  13.01(c) hereof,  which  moneys  in
either  case  shall  have  been  furnished  together  with
directions  that  the  same are  to  be  maintained  in  a
segregated  account or subaccount until  the  same  became
Available  Moneys or (z) proceeds from the investment  and
reinvestment  of  moneys described in clause  (x)  or  (y)
above.

  IV.15.       Custody of Bond Fund; Withdrawal of Moneys.
The  Bond Fund shall be in the custody of the Trustee  but
in  the name of the Pollution Control Corporation and  the
Pollution   Control  Corporation  hereby  authorizes   and
directs  the  Trustee to withdraw from the Bond  Fund  and
furnish to the Paying Agent funds constituting part of the
Trust  Estate  sufficient  to pay  the  principal  of  and
premium,  if  any, and interest on the Bonds as  the  same
shall  become  due and payable, and to withdraw  from  the
Bond  Fund  funds  sufficient to  pay  any  other  amounts
payable  therefrom  as  the  same  shall  become  due  and
payable.

  IV.16.        Bonds Not Presented for Payment.   In  the
event  any  Bonds shall not be presented for payment  when
the  principal thereof and premium, if any, thereon become
due,  either  at  maturity  or  at  the  date  fixed   for
redemption  thereof or otherwise, if moneys sufficient  to
pay  such  Bonds  are  held by the  Paying  Agent  or  any
Co-Paying Agent for the benefit of the Owners thereof, the
Paying  Agent  shall  segregate and hold  such  moneys  in
trust,  without  liability for interest thereon,  for  the
benefit  of  holders of such Bonds, who shall,  except  as
provided   in  the  following  paragraph,  thereafter   be
restricted  exclusively to such  fund  or  funds  for  the
satisfaction of any claim of whatever nature on their part
under this Indenture or relating to said Bonds.

    Any moneys which the Paying Agent shall segregate  and
hold  in  trust  for the payment of the principal  of  and
premium,  if  any, or interest on any Bond  and  remaining
unclaimed  for one year after such principal, premium,  if
any,  or  interest has become due and payable shall,  upon
the Company's written request to the Paying Agent, be paid
to the Company, with notice to the Trustee of such action;
provided,  however,  that, if a  Security  Arrangement  on
which  the  Company shall not be an obligor is in  effect,
prior to any such payment to the Company as aforesaid, the
Paying Agent shall deliver to the Bank a notice specifying
the  date  of such payment (which date shall not  be  less
than four (4) Business Days after the date of delivery  of
such notice), and if prior to such specified date the Bank
shall  have delivered to the Paying Agent a notice stating
that amounts are owed by the Company to the Bank under the
Reimbursement  Agreement  and  have  not  been  paid,  the
Trustee,  prior  to  any such payment to  the  Company  as
aforesaid,  shall pay to the Bank an amount equal  to  the
lesser of (a) the total amount owed by the Company to  the
Bank  as specified in such notice and (b) the total amount
of  such  unclaimed  moneys; and provided,  further,  that
before the Paying Agent shall be required to make any such
repayment, the Paying Agent may, and at the request of the
Trustee shall, at the expense of the Company cause  notice
to  be  given once by Publication to the effect 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 notice by Publication, any unclaimed
balance of such moneys then remaining will be paid to  the
Company.   After the payment of such unclaimed  moneys  to
the  Company, the Owner of such Bond shall thereafter look
only  to  the  Company for the payment  thereof,  and  all
liability of the Trustee and the Paying Agent with respect
to such moneys shall thereupon cease.

  IV.17.        Moneys  Held  in Trust.   All  moneys  and
Investment  Securities held by the  Trustee  in  the  Bond
Fund, and all moneys required to be deposited with or paid
to  the  Trustee for deposit into the Bond Fund,  and  all
moneys  withdrawn  from the Bond  Fund  and  held  by  the
Trustee,  the  Paying Agent, any Co-Paying Agent,  or  the
Tender  Agent,  shall be held by the Trustee,  the  Paying
Agent,  any  Co-Paying Agent or the Tender Agent,  as  the
case  may  be,  in trust, and such moneys  and  Investment
Securities  (other  than moneys held pursuant  to  Section
4.06  hereof and moneys or Investment Securities  held  in
any  subaccount  within  the  Bond  Fund  established   in
furtherance of the obligations of the Company under clause
(b)  of Section 6.04 of the Loan Agreement), while so held
or  so  required to be deposited or paid, shall constitute
part  of  the Trust Estate and be subject to the lien  and
security  interest created hereby in favor of the Trustee,
first, for the benefit of the Owners from time to time  of
the  Bonds and, second, for the benefit of the Bank as and
to  the extent provided herein.  The Company shall have no
right,  title  or interest in the Bond Fund,  except  such
rights as may arise after the right, title and interest of
the  Trustee in and to the Trust Estate and all covenants,
agreements and other obligations of the Pollution  Control
Corporation  under  this  Indenture  shall  have   ceased,
terminated  and become void and shall have been  satisfied
and discharged in accordance with Article VIII hereof.

  IV.18.        Security Arrangements.  (a) The Letter  of
Credit  shall be the obligation of the Bank to pay to  the
Trustee,  in  accordance  with  the  terms  thereof,  such
amounts as shall be specified therein and available to  be
drawn  thereunder for the timely payment of the  principal
of and premium, if any, and interest on the Bonds, and the
purchase price of Bonds, required to be made pursuant  to,
and  in accordance with, the provisions of this Indenture.
Drawings  under  the Letter of Credit for the  payment  of
principal  of,  and premium, if any, and interest  on  the
Bonds  shall be made only to the extent moneys from  other
eligible sources specified in Section 4.04(a) hereof shall
not  be  available for such payment.  The Letter of Credit
shall  be reduced to the extent of any drawings thereunder
and reinstated in accordance with the terms thereof.

    The  Trustee  shall draw moneys under  the  Letter  of
Credit   and   take  action  under  any   other   Security
Arrangement  in accordance with the terms thereof  to  the
extent  necessary to make timely payments of principal  of
and premium, if any, and interest on the Bonds required to
be  made  from  the  Bond Fund; provided,  however,  that,
anything  herein  to the contrary notwithstanding,  in  no
event  shall  the Trustee draw moneys under  any  Security
Arrangement  on  which the Company is not the  obligor  in
order to make payments of principal of or premium, if any,
or  interest on Bonds or the purchase price of Bonds  held
of  record by the Company or by the Tender Agent  for  the
account of the Company pursuant to Section 13.07(d) hereof
if  the  Security Arrangement prohibits  by  its  terms  a
drawing  thereunder for such purpose.  Upon any  reduction
in  the  aggregate principal amount of Bonds  Outstanding,
the  Trustee  shall,  at the direction  of  an  Authorized
Company Representative, request the Bank to make permanent
correlative  reductions in the amounts that may  be  drawn
under  the Letter of Credit or take corresponding  actions
with  respect  to  any  other Security  Arrangement.   For
extensions  of  the term of the Letter of  Credit  or  any
Security  Arrangement, the Trustee shall, at the direction
of an Authorized Company Representative, take such actions
as  are required to effect such extension of the Letter of
Credit,  surrender the Letter of Credit  to  the  Bank  in
exchange for a letter of credit of the Bank conforming  in
all  material respects to the Letter of Credit except that
the   Expiration   date  shall  be   extended   and   take
corresponding  actions with respect to any other  Security
Arrangement.  If at any time there shall cease to  be  any
Bonds  Outstanding hereunder, the Trustee  shall  promptly
surrender  the Letter of Credit to the Bank, in accordance
with  the  terms of the Letter of Credit, for cancellation
or  shall take corresponding actions with respect  to  any
other Security Arrangement.

  (a)   If at any time there shall have been delivered  to
the  Trustee,  all as described in and in accordance  with
the  applicable  provisions of Section 6.07  of  the  Loan
Agreement, (i) a notice of the Company, (ii) the  required
opinion  of  Bond  Counsel, if  any,  (iii)  the  required
certificates or letters of Moody's and S&P,  if  any,  and
(iv)  the Security Arrangement, if any, described in  such
notice,  then  the  Trustee shall accept  such  substitute
Security   Arrangement,  if  any,  and  comply  with   the
direction  of  the  Company, if  any,  contained  in  such
notice.

  (b)    The Trustee shall give notice, in the name of the
Pollution   Control  Corporation,  of  any  amendment   or
Termination or Expiration of any Security Arrangement  and
of  the  provision of any substitute Security Arrangement,
which  notice  shall (i) describe generally  the  Security
Arrangement,  if  any, in effect prior to  any  amendment,
Termination,  Expiration  or provision  and  the  Security
Arrangement,  if any, in effect or to be  in  effect  upon
such  amendment, Termination, Expiration or provision  and
(ii)  state  the  date  of  such  amendment,  Termination,
Expiration  or provision.  Such notice shall be  given  by
Mail to all Owners of Bonds promptly after such amendment,
Termination, Expiration or provision, except that if, as a
result  of such amendment, Termination or Expiration,  the
Bonds shall be required to be tendered for purchase,  such
notice may be given together with the notice thereof given
by  the  Tender Agent pursuant to Section 2.10 hereof  and
shall,  if  such information is furnished by the  Company,
state  the  Rating Category or Categories  (including  any
refinements or gradations thereof), if any, in  which  the
Bonds  are  expected  to  be  rated  by  Moody's  and  S&P
subsequent to such amendment, Termination or Expiration of
a Security Arrangement and the provision of any substitute
Security Arrangement.

  (c)   Anything in this Indenture or the Loan Agreement to
the   contrary  notwithstanding,  in  the  event  that   a
Termination  of a Security Arrangement, or the Termination
of  a  Security Arrangement and the provision  of  another
Security  Arrangement in lieu thereof, shall  require  the
Owners  of  Bonds to tender their Bonds for  purchase  the
Trustee  shall not surrender any evidence of the  Security
Arrangement to be Terminated until the Trustee shall  have
made  such drawings, if any, or taken such other  actions,
if  any,  thereunder  as  shall  be  required  under  this
Indenture  in order to provide sufficient moneys  for  the
related purchase of Bonds and such moneys shall have  been
provided to the Trustee.


V                 THE CONSTRUCTION FUND

  V.11.          Creation  of,  and  Disbursements   from,
Construction  Fund.   (a)  There  is  hereby  created  and
established with the Trustee a trust fund in the  name  of
the   Pollution  Control  Corporation  to  be   designated
"Coconino  County,  Arizona Pollution Control  Corporation
Pollution  Control Revenue Bonds, 1996  Series  A  (Tucson
Electric  Power Company Project) Construction Fund".   The
Trustee   shall   establish  and   maintain   within   the
Construction  Fund a "Capital Account" and an  "Investment
Account".   The Trustee shall establish and  maintain  any
subaccount  within the Capital Account or  the  Investment
Account  which  may be requested by an Authorized  Company
Representative.  The Construction Fund, and all moneys and
certificated  securities therein, shall  be  kept  in  the
possession   of   the  Trustee.   The  Pollution   Control
Corporation   shall   not  create  any   lien   upon   the
Construction Fund other than the lien hereby created.

  (a)    The  proceeds from the issuance and sale  of  the
Bonds, other than accrued interest, if any, on such  Bonds
to  the  date  of  delivery thereof paid  by  the  initial
purchasers  thereof, shall be deposited into  the  Capital
Account.  All income or other gain from the investment  of
moneys  in  the Capital Account or the Investment  Account
shall  be deposited into the Investment Account.   In  the
event  that all or a portion of the proceeds of the  Bonds
shall  have been applied to the payment or redemption,  or
provision  therefor,  of  any obligations  issued  by  the
Pollution  Control  Corporation  other  than  Bonds,   any
balance  remaining  in  the construction,  acquisition  or
other   similar  fund  maintained  in  respect   of   such
obligations,  which balance shall have been  delivered  to
the Trustee accompanied by a direction of the Company that
such  balance  be  deposited into the  Construction  Fund,
shall  be  deposited  into  the Capital  Account  and  the
Investment  Account  in accordance  with  such  direction.
Anything    in   this   Article   V   to   the    contrary
notwithstanding,  in the event that the Company  shall  at
any  time  deliver moneys to the Trustee for deposit  into
the Construction Fund, such moneys shall be deposited into
a  separate  subaccount  therein and,  until  such  moneys
become Available Moneys, shall not be used for the payment
of  principal of or premium, if any, or interest on Bonds,
or  purchase  price of Bonds, except to  the  extent  that
there  shall not be available for such purpose  sufficient
proceeds of a drawing or drawings on the Letter of Credit.

  (b)    The Trustee is hereby authorized and directed  to
disburse  moneys in the Construction Fund to or  upon  the
order of the Company from time to time upon receipt by the
Trustee of requisitions executed by, or communications  by
telegram,  telex  or  facsimile  transmission   from,   an
Authorized  Company Representative, which requisitions  or
communications shall state with respect to each payment to
be  made:  (i) the requisition number, (ii) the  name  and
address of the person, firm or corporation to whom payment
is  due  or has been made (or, in the case of payments  to
the   Bond   Fund,  instructions  to  make  such  payments
thereto),  (iii) the amount paid or to be paid,  (iv)  the
account  or  accounts  within the Construction  Fund  from
which payment of such requisition, or any portion thereof,
shall  be made, (v)(A) that each obligation, item of  cost
or expense with respect to which such requisition is being
made  has been properly incurred and has been paid  or  is
then   due  and  payable  as  an  item  of  the  Cost   of
Construction, is a proper charge against the  Construction
Fund,  and  has  not been the basis of any previous  final
payment  therefrom  or  from the  proceeds  of  any  other
obligations issued by the Pollution Control Corporation or
(B)  in  the event that a portion of the Bonds shall  have
been paid, redeemed or deemed to have been paid within the
meaning   of  Article  VIII  hereof  by  reason   of   the
application of the proceeds of the sale of any obligations
issued under an indenture other than this Indenture and if
the  payment  of such requisition is to be made  into  the
construction,  acquisition or other similar  fund  created
under  such  other indenture, that upon disbursement  from
such construction, acquisition or other similar fund, each
obligation,  item  of  cost or expense  mentioned  in  the
requisition for such disbursement shall have been properly
incurred and shall have been paid or will then be due  and
payable as an item of the Cost of Construction, (vi)  that
the  payment  of  such requisition will not  result  in  a
breach of any of the covenants of the Company contained in
Section  4.04 (c) or (d) of the Loan Agreement  and  (vii)
that,  to  the  best of the knowledge of  such  Authorized
Company Representative, there shall not have occurred  and
be   continuing  any  event  of  default  under  the  Loan
Agreement.   In  Section 4.04 of the  Loan  Agreement  the
Company   has  agreed  that  any  such  communication   by
telegram,  telex  or  facsimile  transmission   shall   be
promptly  confirmed  by  a  requisition  executed  by   an
Authorized Company Representative.

  (c)   In paying any requisition under this Section 5.01,
the   Trustee  shall  be  entitled  to  rely  as  to   the
completeness  and  accuracy  of  all  statements  in  such
requisition  upon the approval of such requisition  by  an
Authorized Company Representative, execution thereof to be
conclusive evidence of such approval, and the Company  has
by  the  provisions of the Loan Agreement  covenanted  and
agreed to indemnify and save harmless the Trustee from any
liability incurred in connection with the payment  of  any
requisition   so   executed  by  an   Authorized   Company
Representative.

    The  Trustee shall keep and maintain adequate  records
pertaining  to  each account within the Construction  Fund
and  all  disbursements therefrom and, upon receipt  of  a
certificate furnished pursuant to Section 3.04 or  Section
3.08(b)  of  the  Loan Agreement, the  Trustee  shall,  if
requested  by  the  Pollution Control Corporation  or  the
Company,  file  an accounting thereof with  the  Pollution
Control Corporation and with the Company.

  V.12.         Completion of Facilities;  Termination  of
Construction.     Upon  receipt  by  the  Trustee   of   a
certificate furnished pursuant to Section 3.04 or  Section
3.08(b)  of  the Loan Agreement, any balance remaining  in
the  Capital Account or the Investment Account  maintained
within  the Construction Fund (other than amounts retained
by the Trustee at the direction of the Company pursuant to
Section  3.04  or  3.08  of  the  Loan  Agreement  or   in
furtherance  of the covenant of the Company  contained  in
clause  (b)  of Section 6.04 of the Loan Agreement)  shall
(a) be applied in whole or in part (i) to the purchase  of
Bonds  in such amounts, at such prices, at such times  and
otherwise   as   directed   by   an   Authorized   Company
Representative, excluding the purchase of  Bonds  pursuant
to  Section  13.03  hereof, or (ii) in  any  other  manner
directed by the Company which, as indicated in an  opinion
of  Bond Counsel furnished by the Company to the Pollution
Control  Corporation and the Trustee, will not impair  the
validity  under the Act of the Bonds or the  exclusion  of
the  interest on the Bonds from gross income  for  federal
income  tax  purposes or (b) in the absence  of  any  such
purchase  or  direction  within sixty  (60)  days  of  the
receipt  by  the  Trustee  of such  certificate  (or  such
shorter  period as the Company shall direct), be deposited
by  the  Trustee into the corresponding account maintained
within  the  Bond Fund.  From time to time as  the  proper
disposition of the amounts retained by the Trustee in  the
Construction Fund as aforesaid shall be determined, to the
extent  that such amounts are not paid out in full by  the
Trustee  pursuant  to  Section 5.01 or  6.01  hereof,  the
Company  shall  so  notify the Trustee and  the  Pollution
Control  Corporation  by  one  or  more  certificates   as
aforesaid  and any amounts from time to time no longer  to
be  so  retained  by  the  Trustee  shall  be  applied  as
aforesaid.    Pending  the  application  of   any   moneys
remaining  in the Construction Fund following the  receipt
of  the aforesaid certificate, such moneys may be invested
in  Investment  Securities  in  the  manner  permitted  by
Section 6.01 hereof, provided that such investments (other
than  investments  made with the moneys  retained  by  the
Trustee  at  the  direction of  the  Company  pursuant  to
Section  3.04  or  3.08 of the Loan Agreement)  shall  not
produce  a  yield  greater than the  yield  on  the  Bonds
unless,  as  indicated  in  an  opinion  of  Bond  Counsel
furnished   by  the  Company  to  the  Pollution   Control
Corporation  and  the  Trustee,  investments  producing  a
greater  yield  would not, in and of  itself,  impair  the
exclusion  from gross income for federal tax  purposes  of
the interest on the Bonds.

  V.13.        Redemption of All Outstanding Bonds.  Except
as set forth in Section 5.05 hereof, in the event that all
Outstanding  Bonds are to be redeemed, the Trustee  shall,
without  further authorization, deposit into  the  General
Account within the Bond Fund all amounts remaining in  the
Construction  Fund constituting part of the Trust  Estate,
with  advice to the Pollution Control Corporation and  the
Company  of  such action, such deposit to be made  on  the
date fixed for such redemption.

  V.14.        Acceleration of Bonds.  In the event that the
principal  of the Bonds shall have become due and  payable
pursuant  to  Section  9.01  hereof,  the  Trustee  shall,
without  further authorization, deposit into  the  General
Account within the Bond Fund all amounts constituting part
of  the  Trust Estate remaining in the Construction  Fund,
with  advice to the Pollution Control Corporation and  the
Company  of  such action, such deposit to be made  on  the
date fixed for such acceleration.

  V.15.        Refunding of Bonds.  In the event that  all
Outstanding  Bonds are paid, redeemed or  deemed  to  have
been  paid  within the meaning of Article VIII  hereof  by
reason  of the application of the proceeds of the sale  of
any  obligations  the  interest on which  is  exempt  from
federal  income  taxation, under an indenture  other  than
this   Indenture,  the  Trustee  shall,  without   further
authorization, withdraw all amounts constituting  part  of
the  Trust Estate remaining in the Capital Account and the
Investment Account maintained within the Construction Fund
and  deposit  such amounts into corresponding accounts  in
the   construction,  acquisition  or  other  similar  fund
created  under the indenture under which such  obligations
are   issued,   with  advice  to  the  Pollution   Control
Corporation   and  the  Company  of  such   action,   such
withdrawals  and  deposits to be made, in accordance  with
the  provisions of such indenture, on the  date  on  which
such  Bonds are so paid, redeemed or deemed to  have  been
paid;  provided,  however, that if Bonds shall  have  been
paid,  redeemed  or deemed to have been  paid  within  the
meaning   of  Article  VIII  hereof  by  reason   of   the
application of the proceeds of the sale of more  than  one
issue  of  obligations the interest on which  is  excluded
from  gross  income for federal income tax purposes  under
indentures  other than this Indenture, the Trustee  shall,
if  directed  by  an  Authorized  Company  Representative,
withdraw all amounts remaining in the Capital Account  and
the  Investment Account maintained within the Construction
Fund  and  such  amounts  shall be  allocated  among,  and
deposited  into,  as  directed by such Authorized  Company
Representative,    corresponding    accounts    in     the
construction,  acquisition or other similar funds  created
under  the  indentures  under which such  obligations  are
issued,  with advice to the Pollution Control  Corporation
and  the  Company  of  such action, such  withdrawals  and
deposits to be made, in accordance with the provisions  of
such  indentures, on the date on which all  Bonds  are  so
paid, redeemed or deemed to have been paid.

  V.16.         Moneys  Held  in Trust.   All  moneys  and
Investment   Securities  held  by  the  Trustee   in   the
Construction Fund, and all moneys required to be deposited
with  or  paid  to  the  Trustee  for  deposit  into   the
Construction  Fund,  and  any moneys  withdrawn  from  the
Construction  Fund and held by the Tender  Agent  for  the
purchase  of  Bonds, shall be held by the Trustee  or  the
Tender Agent, as the case may be, in trust and such moneys
and  Investment Securities (other than any moneys held  by
the  Tender Agent pursuant to Section 13.03(c) hereof  and
moneys  or  Investment Securities held in  any  subaccount
within the Construction Fund established in furtherance of
the  obligations of the Company under Section  6.04(b)  of
the  Loan  Agreement) while so held or so required  to  be
deposited  or  paid, shall constitute part  of  the  Trust
Estate  and  be subject to the lien and security  interest
created hereby in favor of the Trustee for the benefit  of
the  Owners  from time to time of the Bonds.  The  Company
shall have no right, title or interest in the Construction
Fund,  except  that,  to the extent  not  required  to  be
applied in another manner by any provision hereof,  moneys
held  by  the  Trustee in the Construction Fund  shall  be
disbursed  by the Trustee to the Company upon and  to  the
extent  of,  but  solely  upon  and  to  the  extent   of,
satisfaction  of  the  conditions  set  forth  in  Section
5.01(c) hereof.


VI                     INVESTMENTS

  VI.11.       Investments.  The moneys in the Construction
Fund  and in the Bond Fund shall, at the direction of  the
Company,   be   invested  and  reinvested  in   Investment
Securities;  provided, however, that  moneys  constituting
proceeds  of a drawing on a Security Arrangement on  which
the  Company  is  not the obligor and,  while  a  Security
Arrangement on which the Company is not the obligor is  in
effect,  any  moneys held by the Paying Agent pursuant  to
Section  4.06 hereof, or by the Tender Agent  pursuant  to
Section  13.03(c)  hereof,  shall  be  invested  only   in
Government Obligations as described in clause (a)  of  the
definition  thereof  which shall  not  contain  provisions
permitting  the redemption thereof at the  option  of  the
issuer  and  which have a remaining term to  maturity  not
exceeding  30  days and in any event maturing  as  needed.
Any  Investment  Securities may be  purchased  subject  to
options  or  other rights in third parties to acquire  the
same.   In  addition, subject to the proviso contained  in
the  first  sentence of this Section 6.01 and  except  for
moneys  in  the  General Account of  the  Bond  Fund,  the
Trustee shall, at the direction of the Company, enter into
(i)  reverse repurchase agreements, option agreements  and
agreements  to  lend  securities  with  respect   to   any
Investment Securities held by it and (ii) transactions for
the  purchase  or sale of financial futures  contracts  in
obligations  which  constitute  Investment  Securities  or
options  on  financial  futures contracts  in  obligations
which  constitute Investment Securities.  Subject  to  the
further  provisions of this Section 6.01, such investments
shall be made by the Trustee as directed and designated by
the  Company  in  a  certificate of, or telephonic  advice
promptly  confirmed  by a certificate  of,  an  Authorized
Company  Representative.  As and  when  any  amounts  thus
invested   may  be  needed  for  disbursements  from   the
Construction  Fund  or the Bond Fund,  the  Trustee  shall
request  the Company to designate such investments  to  be
sold  or  otherwise converted into cash to the  credit  of
such fund as shall be sufficient to meet such disbursement
requirements  and  shall  then follow  any  directions  in
respect  thereto  of an Authorized Company Representative.
As long as no Event of Default (as defined in Section 9.01
hereof) shall have occurred and be continuing, the Company
shall  have the right to designate the investments  to  be
sold  and to otherwise direct the Trustee in the  sale  or
conversion to cash of the investments made with the moneys
in  the  Construction Fund and in the Bond Fund,  provided
that  the Trustee shall be entitled to conclusively assume
the  absence  of any such Event of Default unless  it  has
notice thereof within the meaning of Section 10.05 hereof.
At  any  time  that S&P or Moody's rates  the  Bonds,  the
General  Account of the Bond Fund may only be invested  in
Investment Securities with a rating level at least as high
as the current rating of the Bonds.

any  such obligation or agreement of the Pollution Control
Corporation   shall   be  construed   to   constitute   an
indebtedness  of the County of Coconino,  Arizona  or  the
State  of Arizona within the meaning of any constitutional
or  statutory  provisions whatsoever.  The Bonds  and  the
interest  and  premium, if any, thereon shall  be  limited

solely  from  the Receipts and Revenues of  the  Pollution
Control Corporation from the Loan Agreement and the  other
moneys pledged therefor.

Bond executed, authenticated and delivered hereunder,  and
in  all  proceedings  pertaining thereto.   The  Pollution
Control  Corporation represents that it is duly authorized
under the Constitution and laws of the State of Arizona to
issue the Bonds authorized hereby, to enter into the  Loan
Agreement and this Indenture, and to pledge and assign  to
the  Trustee the Trust Estate, and that the Bonds  in  the

Company  to  pay or cause to be paid all the payments  and
other  costs and charges payable by the Company under  the
Loan  Agreement and on any Security Arrangement  on  which
the   Company  is  the  obligor.   The  Pollution  Control
Corporation  shall not enter into any agreement  with  the
Company  amending  the Loan Agreement  without  the  prior
written consent of the Trustee and the Bank and compliance
with  Sections  12.06  and  12.07  of  this  Indenture  (a
revision  to  Exhibit  A to the Loan Agreement  not  being
deemed an amendment for purposes of this Section).

  VII.15.      Further Instruments.  The Pollution Control
Corporation  shall,  upon the reasonable  request  of  the
Trustee,  from  time  to  time execute  and  deliver  such
further instruments and take such further action as may be
reasonable  and  as  may  be required  to  carry  out  the
purposes  of  this Indenture; provided, however,  that  no
such  instruments or actions shall pledge  the  credit  or

political subdivision of said State.

appropriate  state and county offices as required  by  the
provisions of the Uniform Commercial Code or other similar
law  as  adopted  in the State of Arizona  and  any  other
applicable jurisdiction, as from time to time amended,  in
order  to  perfect  and  maintain the  security  interests
created by this Indenture.

  VII.18.       Tax  Covenants;  Rebate  Fund.   (a)   The
Pollution Control Corporation covenants for the benefit of
all  Owners  from time to time of the Bonds and  the  Bank
that  it  will not directly or indirectly use or  (to  the
extent  within  its  control),  permit  the  use  of,  the
proceeds  of  any of the Bonds or any other funds  of  the
Pollution Control Corporation, or take or omit to take any
other  action, if and to the extent that such use, or  the
taking or omission to take such action, would cause any of
the  Bonds  to be "arbitrage bonds" within the meaning  of
Section  148 of the Code or otherwise subject  to  federal
income  taxation by reason of Sections 103 and 141 through
150  of  the  Code  or Section 103 of the  1954  Code,  as
applicable,  and  any  applicable regulations  promulgated
thereunder.  To that end the Pollution Control Corporation
covenants  to comply with all covenants set forth  in  the
Tax  Agreement,  which  is hereby incorporated  herein  by
reference as though fully set forth herein.

  (a)     The Trustee shall establish and maintain a  fund
separate  from  any other fund established and  maintained
hereunder   designated  the  "Coconino   County,   Arizona
Pollution  Control Corporation Pollution  Control  Revenue
Bonds,  1996  Series  A  (Tucson  Electric  Power  Company
Project)  Rebate Fund" (herein called the "Rebate  Fund").
Within  the  Rebate Fund, the Trustee shall maintain  such
accounts as shall be directed by the Company in order  for
the  Pollution  Control Corporation  and  the  Company  to
comply  with the provisions of the Tax Agreement.  Subject
to  the  transfer  provisions provided  in  paragraph  (c)
below, all money at any time deposited in the Rebate  Fund
shall  be  held  by the Trustee in trust,  to  the  extent
required to satisfy the Rebate Requirement (as defined  in
the  Tax  Agreement), for payment to the United States  of
America,  and  neither the Company, the Pollution  Control
Corporation  or  the Owners shall have any  rights  in  or
claim  to such moneys.  All amounts deposited into  or  on
deposit  in  the  Rebate Fund shall be  governed  by  this
Section 7.08, by Section 6.04 of the Loan Agreement and by
the  Tax  Agreement.   The Trustee shall  conclusively  be
deemed to have complied with such provisions if it follows
the  directions  of the Company, including  supplying  all
necessary information in the manner set forth in  the  Tax
Agreement,  and shall not be required to take any  actions
thereunder in the absence of written directions  from  the
Company.

  (b)    Upon receipt of the Company's written instructions,
the Trustee shall remit part or all of the balances in the
Rebate  Fund  to  the  United States  of  America,  as  so
directed.   In  addition, if the Company so  directs,  the
Trustee  shall deposit moneys into or transfer moneys  out
of  the Rebate Fund from or into such accounts or funds as
directed  by the Company's written directions.  Any  funds
remaining in the Rebate Fund after all of the Bonds  shall
have  been paid and any Rebate Requirement shall have been
satisfied,  or provision therefor reasonably  satisfactory
to the Trustee shall have been made, and all amounts owing
to  the  Bank under the Reimbursement Agreement have  been
paid, shall be withdrawn and remitted to the Company.

  (c)     Notwithstanding any provision of this Indenture,
the  obligation  to  remit the Rebate Requirement  to  the
United  States  of America and to comply  with  all  other
requirements  of this Section 7.08, Section  6.04  of  the
Loan  Agreement  and the Tax Agreement shall  survive  the
payment of the Bonds and the satisfaction and discharge of
this Indenture.

  VII.19.      Notices of Trustee.  The Trustee shall give
notice  to both the Pollution Control Corporation and  the
Company  whenever it is required hereby to give notice  to
either  and, additionally, shall furnish to the  Pollution
Control  Corporation and the Company copies of any  notice
by  mailing  or  Publication given by it pursuant  to  any
provision hereof.

  VII.2      0. No Transfer of Security Arrangement.   The
Trustee  shall not sell, assign or transfer  any  Security
Arrangement  except  to  a successor  trustee  under  this
Indenture.


VIII                    DEFEASANCE

  VIII.11.      Defeasance.   If  the  Pollution   Control
Corporation shall pay or cause to be paid to the Owner  of
any  Bond secured hereby the principal of and premium,  if
any,  and  interest  due and payable,  and  thereafter  to
become due and payable, upon such Bond or, if not during a
Flexible  Rate  Period or Term Rate Period or  Fixed  Rate
Period, any portion of any Bond in the principal amount of
$100,000 or any integral multiple thereof, or, if during a
Flexible  Rate  Period or Term Rate Period or  Fixed  Rate
Period,  any portion of such Bond in the principal  amount
of  $5,000 or any integral multiple thereof (and,  in  the
case  of  a  Flexible Rate Period, in a minimum  principal
amount  of  $100,000), such Bond or portion thereof  shall
cease  to  be  entitled to any lien, benefit  or  security
under   this   Indenture.    If  the   Pollution   Control
Corporation shall pay or cause to be paid to the Owners of
all the Bonds secured hereby the principal of and premium,
if  any,  and interest due and payable, and thereafter  to
become due and payable, thereon, and shall pay or cause to
be  paid  all  other  sums  payable  hereunder  including,
without  limitation, amounts payable pursuant  to  Section
10.04 hereof, then, and in that case, the right, title and
interest  of the Trustee in and to the Trust Estate  shall
thereupon  cease,  terminate and  become  void.   In  such
event, the Trustee shall assign, transfer and turn over to
the   Company   the   Trust  Estate,  including,   without
limitation,  any surplus in the Bond Fund and any  balance
remaining  in any other fund created under this Indenture;
provided,  however,  that, if a  Security  Arrangement  on
which  the  Company shall not be an obligor is in  effect,
prior to any such assignment, transfer and turning over to
the Company as aforesaid, the Trustee shall deliver to the
Bank  a  notice  specifying the date of  such  assignment,
transfer  and turning over (which date shall not  be  less
than four (4) Business Days after the date of delivery  of
such notice), and if prior to such specified date the Bank
shall have delivered to the Trustee a notice stating  that
amounts  are  owed by the Company to the  Bank  under  the
Reimbursement  Agreement  and  have  not  been  paid,  the
Trustee,  prior  to  any  such  assignment,  transfer  and
turning over to the Company as aforesaid, shall pay to the
Bank an amount equal to the lesser of (a) the total amount
owed  by  the  Company to the Bank as  specified  in  such
notice  and  (b) the total amount remaining in  all  funds
created under this Indenture.

    All  or  any portion of Outstanding Bonds or,  if  not
during  a Flexible Rate Period, a Term Rate Period or  the
Fixed  Rate Period, portions of Bonds in principal amounts
of $100,000 or any integral multiple thereof or, if during
a  Flexible Rate Period, a Term Rate Period or  the  Fixed
Rate  Period,  portions of Bonds in principal  amounts  of
$5,000 or any integral multiple thereof (and, in the  case
of  a  Flexible Rate Period, in a minimum principal amount
of  $100,000),  shall prior to the maturity or  redemption
date  thereof  be  deemed to have  been  paid  within  the
meaning  and  with the effect expressed  in  this  Article
VIII, and the entire indebtedness of the Pollution Control
Corporation  with respect thereof shall be  satisfied  and
discharged, when

     (a)   in the event said Bonds or portions thereof have
  been  selected for redemption in accordance with Section
  3.02 hereof, the Trustee shall have given, or the Company
  shall have given to the Trustee in form satisfactory to it
  irrevocable instructions to give, on a date in accordance
  with  the  provisions of Section 3.03 hereof  notice  of
  redemption of such Bonds or portions thereof,

     (b)   there shall have been deposited with the Trustee
  either moneys in an amount which shall be sufficient, or,
  during the Fixed Rate Period, Government Obligations which
  shall  not  contain provisions permitting the redemption
  thereof at the option of the issuer, the principal of and
  the interest on which, when due, and without regard to any
  reinvestment thereof, will provide moneys which, together
  with  the moneys, if any, deposited with or held by  the
  Trustee,  shall  be  sufficient, to  pay  when  due  the
  principal of and premium, if any, and interest  (at  the
  Maximum Rate, if such deposit shall not be made during the
  Fixed Rate Period) due and to become due on said Bonds or
  portions thereof on and prior to the redemption date  or
  maturity  date  thereof, as the case may  be;  provided,
  however,  that  such  moneys shall constitute  Available
  Moneys  and that such Government Obligations either  (i)
  shall have been purchased with Available Moneys or, (ii)
  shall have been held by the Trustee for the period of time
  for which the moneys used for the purchase thereof would
  be  required to be so held in order for such  moneys  to
  constitute  Available  Moneys if such  moneys  had  been
  deposited  with  the Trustee and the  purchase  of  such
  Government Obligations were disregarded, and

     (c)   in the event said Bonds or portions thereof do not
  mature  and  are  not  to be redeemed  within  the  next
  succeeding sixty (60) days, the Company shall have given
  the  Trustee  in  form satisfactory  to  it  irrevocable
  instructions to give, as soon as practicable in the same
  manner  as  a notice of redemption is given pursuant  to
  Section 3.03 hereof, a notice to the holders of said Bonds
  or  portions thereof that the deposit required by clause
  (b)  above has been made with the Trustee and that  said
  Bonds or portions thereof are deemed to have been paid in
  accordance with this Article VIII and stating the maturity
  or redemption date upon which moneys are to be available
  for the payment of the principal of and premium, if any,
  and interest on said Bonds or portions thereof.

    Notwithstanding the foregoing, no Bond shall be deemed
paid  and discharged pursuant to this Section 8.01  during
any  period  when a Letter of Credit is in  effect  unless
written  evidence is received from S&P,  if  S&P  is  then
rating  the Bonds, and Moody's, if Moody's is then  rating
the  Bonds, that such defeasance will not adversely affect
the ratings on the Bonds.

   Neither the Government Obligations nor moneys deposited
with  the  Trustee  pursuant  to  this  Article  VIII  nor
principal  or  interest payments on  any  such  Government
Obligations  shall be withdrawn or used  for  any  purpose
other  than, and such Government Obligations,  moneys  and
principal or interest payments shall be held in trust for,
the  payment of the principal of and premium, if any,  and
interest  on said Bonds or portions thereof,  or  for  the
payment  of the purchase price of said Bonds in accordance
with  Section 13.03 hereof; provided, that, prior  to  the
Fixed Rate Date, such moneys, if not then needed for  such
purposes,  shall, to the extent practicable,  be  invested
and  reinvested in Government Obligations maturing  on  or
prior  to  the  earlier of (a) the date  moneys  shall  be
required  for  the purchase of Bonds pursuant  to  Section
13.03  hereof  and  (b)  the Interest  Payment  Date  next
succeeding  the  date of investment or  reinvestment,  and
interest  earned from such investments shall be paid  over
to the Company, as received by the Trustee, free and clear
of  any  trust,  lien or pledge hereunder;  and  provided,
further,  that,  during the Fixed Rate  Period,  any  cash
received from such principal or interest payments on  such
Government Obligations deposited with the Trustee, if  not
then  needed  for  such  purposes, shall,  to  the  extent
practicable, be invested in Government Obligations of  the
type  described  in  clause  (b)  of  the  next  preceding
paragraph  maturing at times and in amounts sufficient  to
pay  when  due the principal of and premium, if  any,  and
interest  to become due on said Bonds or portions  thereof
on  and  prior  to such redemption date or  maturity  date
thereof, as the case may be, and interest earned from such
reinvestments  shall  be  paid over  to  the  Company,  as
received by the Trustee, free and clear of any trust, lien
or  pledge  hereunder.  If payment of less  than  all  the
Bonds  is  to be provided for in the manner and  with  the
effect  provided in this Article VIII, the  Trustee  shall
select  such  Bonds  or portions of Bonds  in  the  manner
specified  by  Section  3.02  hereof  for  selection   for
redemption of less than all Bonds in the principal  amount
designated  to the Trustee by the Company.  If  the  Bonds
are  rated  by S&P or Moody's, Government Obligations  for
purposes  of this Section 8.01 shall be limited  to  those
described in clause (a) of such definition and at or prior
to  the  time of the deposit of any Government Obligations
with  the  Trustee  pursuant to  this  Section  8.01,  the
Company  shall provide S&P and Moody's with a  certificate
of  an accountant or accounting firm as to the sufficiency
of  such  Government  Obligations  to  pay  when  due  the
principal of and premium, if any, and interest due and  to
become  due  as  set forth in clause (b) of the  preceding
paragraph.


IX                DEFAULTS AND REMEDIES

  IX.11.        Events of Default.  Each of the  following
events  shall  constitute  and  is  referred  to  in  this
Indenture as an "Event of Default":

     (a)   a failure to pay the principal of or premium, if
  any, on any of the Bonds when the same shall become  due
  and payable at maturity, upon redemption or otherwise;

     (b)   a failure to pay an installment of interest on any
  of the Bonds after such interest shall have become due and
  payable  for a period of two (2) Business Days, if  such
  failure shall occur in respect of interest determined at a
  Flexible Rate or a Variable Rate other than a Term Rate,
  or for a period of sixty (60) days, if such failure shall
  occur in respect of interest determined at a Term Rate or
  the Fixed Rate;

     (c)   a failure to pay an amount due in respect of  a
  tender  for purchase after such amount shall have become
  due and payable;

     (d)   a failure by the Pollution Control Corporation to
  observe and perform any covenant, condition, agreement or
  provision (other than as specified in clauses (a), (b) and
  (c)  of this Section 9.01) contained in the Bonds or  in
  this  Indenture  on  the part of the  Pollution  Control
  Corporation  to be observed or performed, which  failure
  shall  continue for a period of ninety (90)  days  after
  written  notice, specifying such failure and  requesting
  that  it  be  remedied, shall have  been  given  to  the
  Pollution  Control Corporation and the  Company  by  the
  Trustee, which may give such notice in its discretion and
  which  shall give such notice at the written request  of
  Owners  of not less than 25% in principal amount of  the
  Bonds then Outstanding or of the Bank, unless the Trustee,
  or the Trustee and Owners of a principal amount of Bonds
  not less than the principal amount of Bonds the Owners of
  which requested that such notice be given or the Bank, 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 Owners of such
  principal amount of Bonds or the Bank, as the case may be,
  shall  be deemed to have agreed to an extension of  such
  period if corrective action is initiated by the Pollution
  Control  Corporation, or the Company on  behalf  of  the
  Pollution Control Corporation, within such period and is
  being diligently pursued.

    Upon  the occurrence and continuance of any  Event  of
Default  described  in  clause (a),  (b)  or  (c)  of  the
preceding  paragraph, the Trustee may, and at the  written
request of Owners of not less than 25% in principal amount
of Bonds then Outstanding or of the Bank shall, by written
notice to the Pollution Control Corporation, the Bank  and
the  Company, declare the Bonds to be immediately due  and
payable,  whereupon  they shall, without  further  action,
become  and  be immediately due and payable,  anything  in
this   Indenture   or  in  the  Bonds  to   the   contrary
notwithstanding, and the Trustee shall give notice thereof
to  the Tender Agent and the Remarketing Agent, and  shall
give  notice  thereof by Mail to all Owners of Outstanding
Bonds;  provided, however, that so long as the  Letter  of
Credit shall be in effect and no drawing on the Letter  of
Credit  shall  have  been,  and shall  remain,  wrongfully
dishonored, the Trustee shall not declare the acceleration
of  the  maturity of the Bonds without the consent of  the
Bank.  In the case of an Event of Default described in the
preceding  paragraph occurring when a Security Arrangement
on which the Company shall not be the obligor is in effect
and  with  respect  to which the Trustee  is  required  to
accelerate the Bonds, the Trustee shall make the aforesaid
declaration on the first Business Day after the occurrence
of  such Event of Default on which the Trustee may make  a
drawing  or drawings on such Security Arrangement  and  on
which  the proceeds of such drawing or drawings  shall  be
immediately available, but shall not make such declaration
prior  to such date.  With respect to an Event of  Default
described  in  the  preceding paragraph occurring  when  a
Security Arrangement on which the Company shall not be the
obligor  is  in  effect, but with  respect  to  which  the
Trustee  is  not  required to accelerate  the  Bonds,  the
Trustee may make the aforesaid declaration only on a  date
when  the Trustee may make a drawing or drawings  on  such
Security Arrangements.  Upon such declaration, interest on
the Bonds shall cease to accrue.

   The provisions of the preceding paragraph, however, are
subject, when no Security Arrangement on which the Company
shall  not  be  the  obligor shall be in  effect,  to  the
condition that if, after the principal of the Bonds  shall
have  been  so declared to be due and payable, and  before
any  judgment or decree for the payment of the moneys  due
shall   have  been  obtained  or  entered  as  hereinafter
provided, the Pollution Control Corporation shall cause to
be  deposited with the Trustee a sum sufficient to pay all
matured  installments of interest upon all Bonds  and  the
principal of any and all Bonds which shall have become due
otherwise  than  by  reason  of  such  declaration   (with
interest   upon   such  principal  and,  to   the   extent
permissible  by law, on overdue installments of  interest,
at the rate per annum borne by the Bonds) and such amounts
as  shall  be  sufficient to cover reasonable compensation
and  reimbursement of expenses payable to the Trustee  and
any   predecessor  Trustee,  and  all  Events  of  Default
hereunder other than nonpayment of the principal of  Bonds
which shall have become due by said declaration shall have
been  remedied, then, in every such case,  such  Event  of
Default  shall  be deemed waived and such declaration  and
its  consequences rescinded and annulled, and the  Trustee
shall   promptly  give  written  notice  of  such  waiver,
rescission   and   annulment  to  the  Pollution   Control
Corporation,  the  Company,  the  Tender  Agent  and   the
Remarketing  Agent, and, if notice of the acceleration  of
the  Bonds  shall  have been given to the  Owners  of  the
Bonds, shall give notice thereof by Mail to all Owners  of
Outstanding  Bonds;  but  no such waiver,  rescission  and
annulment  shall extend to or affect any subsequent  Event
of  Default  or  impair  any right  or  remedy  consequent
thereon.

  IX.12.         Remedies.    Upon  the   occurrence   and
continuance  of any Event of Default, then  and  in  every
such case the Trustee in its discretion may, and upon  the
written request of the Bank or Owners of not less than 25%
in  principal  amount  of the Bonds then  Outstanding  and
receipt of indemnity to its satisfaction shall, in its own
name and as the Trustee of an express trust:

     (a)   by mandamus, or other suit, action or proceeding at
  law or in equity, enforce all rights of the Owners of the
  Bonds, and require the Pollution Control Corporation, the
  Bank or the obligor on any other Security Arrangement or
  the  Company to carry out any agreements with or for the
  benefit of such Owners and to perform its or their duties
  under the Act, the Loan Agreement, the Letter of Credit or
  other Security Arrangement and this Indenture;

     (b)   bring suit upon the Bonds; or

     (c)   by action or suit in equity enjoin any acts  or
  things which may be unlawful or in violation of the rights
  of the Owners of the Bonds.

   The Trustee shall give to the Bank prompt notice of its
election  of  any  one or more of the foregoing  remedies,
anything herein to the contrary notwithstanding,  so  long
as  the Letter of Credit shall be in effect and no drawing
on the Letter of Credit shall have been, and shall remain,
wrongfully dishonored, the Trustee shall not pursue any of
such remedies without the consent of the Bank.

  IX.13.       Restoration to Former Position.  In the event
that  any  proceeding taken by the Trustee to enforce  any
right under this Indenture shall have been discontinued or
abandoned  for  any reason, or shall have been  determined
adversely  to  the  Trustee, then  the  Pollution  Control
Corporation, the Trustee and the Owners shall be restored,
subject to any determination in such proceeding, to  their
former  positions and rights hereunder, respectively,  and
all  rights,  remedies  and powers of  the  Trustee  shall
continue as though no such proceeding had been taken.

  IX.14.         Bank's   or  Owners'  Right   to   Direct
Proceedings.   Anything in this Indenture to the  contrary
notwithstanding,  the  Bank or Owners  of  a  majority  in
principal  amount of the Bonds then Outstanding  hereunder
shall have the right, by an instrument in writing executed
and  delivered to the Trustee, to direct the time,  method
and place of conducting all remedial proceedings available
to  the  Trustee  under this Indenture or  exercising  any
trust or power conferred on the Trustee by this Indenture;
provided, however, that the Bank shall have no such rights
in  respect  of  remedies against the Bank; and  provided,
further,  that such direction shall not be otherwise  than
in   accordance  with  law  and  the  provisions  of  this
Indenture  and that the Trustee shall have the right  (but
not   the  obligation)  to  decline  to  follow  any  such
direction if the Trustee, being advised by counsel,  shall
determine  that the action or proceeding so  directed  may
not  lawfully  be taken, or if the Trustee in  good  faith
shall determine that the action or proceedings so directed
would involve the Trustee in personal liability or if  the
Trustee  in good faith shall so determine that the actions
or forbearances specified in or pursuant to such direction
would be unduly prejudicial to the interests of Owners not
joining  in  the  giving  of  said  direction,  it   being
understood  that  the  Trustee  shall  have  no  duty   to
ascertain whether or not such actions or forbearances  are
unduly  prejudicial to such Owners.  In  the  event  of  a
conflict  between the directions of the Bank and those  of
the  Owners of the Bonds, so long as the Letter of  Credit
shall  be in effect and no drawing on the Letter of Credit
shall  have  been, and shall remain wrongfully dishonored,
the  directions of the Bank shall prevail; otherwise,  the
directions of the Owners of the Bonds shall prevail.

  IX.15.        Limitation on Owners' Right  to  Institute
Proceedings.   No Owner of Bonds shall have any  right  to
institute any suit, action or proceeding in equity  or  at
law for the execution of any trust or power hereunder,  or
any  other remedy hereunder or on said Bonds, unless  such
Owner  previously shall have given to the Trustee  written
notice of an Event of Default as hereinabove provided  and
unless the Owners of not less than 25% in principal amount
of  the  Bonds  then Outstanding shall have  made  written
request  of  the  Trustee so to do,  after  the  right  to
institute  said  suit,  action or  proceeding  shall  have
accrued,  and shall have afforded the Trustee a reasonable
opportunity to proceed to institute the same in either its
or  their  name,  and unless there also  shall  have  been
offered to the Trustee security and indemnity satisfactory
to  it  against the costs, expenses and liabilities to  be
incurred  therein  or thereby, and the Trustee  shall  not
have  complied with such request within a reasonable time;
and  such notification, request and offer of indemnity are
hereby  declared in every such case, at the option of  the
Trustee, to be conditions precedent to the institution  of
said  suit, action or proceeding; it being understood  and
intended  that no one or more of the Owners of  the  Bonds
shall  have  any right in any manner whatever  by  his  or
their  action to affect, disturb or prejudice the security
of  this  Indenture, or to enforce any right hereunder  or
under the Bonds, except in the manner herein provided, and
that  all  suits, actions and proceedings  at  law  or  in
equity  shall  be  instituted, had and maintained  in  the
manner  herein provided and for the equal benefit  of  all
Owners of the Bonds.  No Owner of any Bond shall have  any
right to make a drawing on a Security Arrangement on which
the  Company shall not be the obligor or to institute  any
suit, action or proceeding in equity or at law against the
Bank  to  enforce a drawing on a Security  Arrangement  on
which the Company shall not be the obligor.

  IX.16.        No Impairment of Right to Enforce Payment.
Notwithstanding any other provision in this Indenture, the
right  of  any Owner of a Bond to receive payment  of  the
principal  of  and premium, if any, and interest  on  such
Bond,  on  or  after  the respective due  dates  expressed
therein, or to institute suit for the enforcement  of  any
such payment on or after such respective dates, shall  not
be impaired or affected without the consent of such Owner.

  IX.17.       Proceedings by Trustee without Possession of
Bonds.  All rights of action under this Indenture or under
any  of the Bonds secured hereby which are enforceable  by
the  Trustee may be enforced by it without the  possession
of  any  of  the Bonds, or the production thereof  on  the
trial or other proceedings relative thereto, and any  such
suit, action or proceeding instituted by the Trustee shall
be  brought in its name for the equal and ratable  benefit
of  the Owners of the Bonds, subject to the provisions  of
this Indenture.

  IX.18.        No  Remedy  Exclusive.  No  remedy  herein
conferred upon or reserved to the Trustee or to the Owners
of  the  Bonds  is intended to be exclusive of  any  other
remedy  or remedies, and each and every such remedy  shall
be  cumulative,  and shall be in addition to  every  other
remedy given hereunder, under the Loan Agreement or  under
any Security Arrangement, now or hereafter existing at law
or in equity or by statute.

  IX.19.       No Waiver of Remedies.  No delay or omission
of  the Trustee or of any Owner of a Bond to exercise  any
right or power accruing upon any default shall impair  any
such  right or power or shall be construed to be a  waiver
of any such default, or an acquiescence therein; and every
power  and remedy given by this Article IX to the  Trustee
and  to  the  Owners  of the Bonds, respectively,  may  be
exercised from time to time and as often as may be  deemed
expedient.

  IX.2 0. Application of Moneys.  Any moneys received by the
Trustee,  by  any  receiver or by  any  Owner  of  a  Bond
pursuant  to  any  right given or action taken  under  the
provisions of this Article IX, after payment of the  costs
and   expenses  of  the  proceedings  resulting   in   the
collection  of such moneys and of all amounts due  to  the
Trustee  and  any predecessor Trustee under Section  10.04
hereof, shall be deposited in the Bond Fund and all moneys
so deposited in the Bond Fund during the continuance of an
Event  of  Default (other than moneys for the  payment  of
Bonds  which had matured or otherwise become payable prior
to  such  Event of Default or for the payment of  interest
due  prior  to such Event of Default) shall be applied  as
follows  (provided,  however,  that  any  drawing  by  the
Trustee  on  any Security Arrangement for the  payment  of
principal of, or premium, if any, or interest on the Bonds
shall  be applied only to the payment of the principal  of
or  premium, if any, or interest on the Bonds pursuant  to
the terms of the Security Arrangement):

     (a)   Unless the principal of all the Bonds shall have
  become due and payable, all such moneys shall be applied
  (i) first, to the payment to the persons entitled thereto
  of  all  installments of interest then due on the Bonds,
  with interest on overdue installments, if lawful, at the
  rate  per  annum  borne by the Bonds, in  the  order  of
  maturity of the installments of such interest and, if the
  amount available shall not be sufficient to pay in  full
  any  particular  installment of interest,  then  to  the
  payment  ratably, according to the amounts due  on  such
  installment,  and  (ii) second, to the  payment  to  the
  persons entitled thereto of the unpaid principal of any of
  the  Bonds which shall have become due (other than Bonds
  called for redemption for the payment of which money  is
  held pursuant to the provisions of this Indenture), with
  interest on such Bonds at their rate from the respective
  dates  upon  which they became due and,  if  the  amount
  available shall not be sufficient to pay in full Bonds due
  on any particular date, together with such interest, then
  to  the  payment  ratably, according to  the  amount  of
  principal and interest due on such date, in each case to
  the persons entitled thereto, without any discrimination
  or privilege; provided, however, that moneys derived from
  the rights of the Trustee under any Security Arrangement
  on which the Company shall not be the obligor shall not be
  applied to the payment of the principal of or premium, if
  any, or interest on Bonds held of record by the Company,
  or  by  the Tender Agent for the account of the  Company
  pursuant  to  Section 13.07(c) hereof, if such  Security
  Arrangement prohibits by its terms a drawing  thereunder
  for such purpose.

     (b)   If the principal of all the Bonds shall have become
  due and payable, all such moneys shall be applied to the
  payment of the principal and interest then due and unpaid
  upon  the  Bonds, with interest on overdue interest  and
  principal, as aforesaid, without preference or priority of
  principal over interest or of interest over principal, or
  of any installment of interest over any other installment
  of interest, or of any Bond over any other Bond, ratably,
  according  to the amounts due respectively for principal
  and interest, to the persons entitled thereto without any
  discrimination  or  privilege; provided,  however,  that
  moneys derived from the rights of the Trustee under  any
  Security Arrangement in which the Company shall not be the
  obligor  shall  not  be applied to the  payment  of  the
  principal of or premium, if any, or interest on Bonds held
  of record by the Company, or by the Tender Agent for the
  account  of  the  Company pursuant to  Section  13.07(c)
  hereof,  if such Security Arrangement prohibits  by  its
  terms a drawing thereunder for such purpose.

     (c)   If the principal of all the Bonds shall have come
  due and payable, and if acceleration of the maturity  of
  the  Bonds  by  reason of such Event  of  Default  shall
  thereafter  have been rescinded and annulled  under  the
  provisions  of  this Article IX, then,  subject  to  the
  provisions of clause (b) of this Section 9.10 which shall
  be applicable in the event that the principal of all the
  Bonds shall later become due and payable, the moneys shall
  be applied in accordance with the provisions of clause (a)
  of this Section 9.10.

  IX.22.       Severability of Remedies.  It is the purpose
and  intention  of this Article IX to provide  rights  and
remedies  to  the  Trustee and the  Owners  which  may  be
lawfully  granted under the provisions  of  the  Act,  but
should  any right or remedy herein granted be held  to  be
unlawful, the Trustee and the Owners shall be entitled, as
above  set forth, to every other right and remedy provided
in this Indenture and by law.


X    TRUSTEE; PAYING AGENT AND CO-PAYING AGENTS; REGISTRAR


  X.11.         Acceptance of Trusts.  The Trustee  hereby
accepts  and agrees to execute the trusts hereby  created,
but  only  upon  the additional terms set  forth  in  this
Article   X,  to  all  of  which  the  Pollution   Control
Corporation  agrees  and the respective  Owners  agree  by
their acceptance of delivery of any of the Bonds.

  X.12.          No  Responsibility  for  Recitals.    The
recitals, statements and representations contained in this
Indenture  or  in  the  Bonds,  save  only  the  Trustee's
authentication  upon  the  Bonds,  are  not  made  by  the
Trustee,  and the Trustee does not assume, and  shall  not
have, any responsibility or obligation for the correctness
of any thereof.  The Trustee makes no representation as to
the  validity  or  sufficiency of this  Indenture  or  the
Bonds.

  X.13.        Limitations on Liability.  The Trustee  may
execute any of the trusts or powers hereof and perform the
duties  required of it hereunder by or through  attorneys,
agents, receivers, or employees, and shall be entitled  to
advice of counsel concerning all matters of trust and  its
duty  hereunder, and the Trustee shall not  be  answerable
for the default or misconduct of any such attorney, agent,
receiver, or employee selected by it with reasonable care.
The  Trustee  shall not be answerable for the exercise  of
any  discretion  or  power under  this  Indenture  or  for
anything  whatsoever in connection with the trust  created
hereby, except only for its own negligence or bad faith.

     Anything   in   this  Indenture   to   the   contrary
notwithstanding, the Trustee shall in no event be required
to  expend  or  risk  its  own funds  or  otherwise  incur
personal financial liability in the performance of any  of
its  duties  or  in the exercise of any of its  rights  or
powers, if there shall be reasonable grounds for believing
that  the  repayment  of such funds or adequate  indemnity
against such liability is not reasonably assured to it.

  X.14.         Compensation, Expenses and Advances.   The
Trustee,  the  Paying Agent and any Co-Paying  Agent,  the
Registrar,  the  Tender  Agent and the  Remarketing  Agent
under  this  Indenture  shall be  entitled  to  reasonable
compensation  for their services rendered  hereunder  (not
limited by any provision of law regarding the compensation
of  the  trustee of an express trust) and to reimbursement
for their actual out-of-pocket expenses (including counsel
fees)  reasonably incurred in connection therewith  except
as  a  result of their negligence or bad faith, including,
without   limitation,  compensation   for   any   services
rendered, and reimbursement for any expenses incurred,  at
and  subsequent to the time the Bonds are deemed  to  have
been paid in accordance with Article VIII hereof.  If  the
Pollution Control Corporation shall fail to perform any of
the  covenants or agreements contained in this  Indenture,
other  than the covenants or agreements in respect of  the
payment  of  the  principal of and premium,  if  any,  and
interest   on   the  Bonds,  the  Trustee  may,   in   its
uncontrolled discretion and without notice to  the  Owners
of  the  Bonds,  at any time and from time to  time,  make
advances  to effect performance of the same on  behalf  of
the  Pollution Control Corporation, but the Trustee  shall
be  under  no  obligation so to do; and any and  all  such
advances  may  bear  interest at  a  rate  per  annum  not
exceeding  the  base  rate  then  in  effect  for   90-day
commercial  loans  by the Trustee or a commercial  banking
affiliate of the Trustee designated as such by the Trustee
in  the  city in which is located the Principal Office  of
the  Trustee (or such affiliate, as the case  may  be)  to
borrowers  of  the highest credit standing;  but  no  such
advance  shall  operate to relieve the  Pollution  Control
Corporation  from any default hereunder.  In Section  5.03
of the Loan Agreement, the Company has agreed that it will
pay  to  the Trustee (including any predecessor  Trustee),
the  Paying  Agent and any Co-Paying Agent, the Registrar,
the   Tender   Agent  and  the  Remarketing  Agent,   such
compensation  and reimbursement of expenses and  advances,
but the Company may, without creating a default hereunder,
contest  in  good  faith the reasonableness  of  any  such
services,  expenses and advances.  If  the  Company  shall
have  failed  to  make any payment to the Trustee  or  any
predecessor  Trustee  under  Section  5.03  of  the   Loan
Agreement and such failure shall have resulted in an Event
of  Default under the Loan Agreement, the Trustee, and any
predecessor Trustee, shall have, in addition to any  other
rights  hereunder,  a claim, prior to  the  claim  of  the
Owners,  for  the  payment  of its  compensation  and  the
reimbursement of its expenses and any advances made by it,
as  provided  in this Section 10.04, upon the  moneys  and
obligations  in  the  Bond Fund; provided,  however,  that
neither the Trustee nor any predecessor Trustee shall have
any  such  claim upon proceeds of drawings on  a  Security
Arrangement on which the Company shall not be the  obligor
or  upon  moneys or obligations deposited with or paid  to
the  Trustee for the redemption or payment of Bonds  which
are  deemed  to have been paid in accordance with  Article
VIII  hereof; and provided, further, that, so  long  as  a
Security Arrangement on which the Company shall not be the
obligor  is  in  effect,  neither  the  Trustee  nor   any
predecessor  Trustee shall have any such  claim  upon  any
moneys  or  obligations  in the Bond  Fund  unless,  after
satisfaction of such claim, there shall remain in the Bond
Fund  moneys  sufficient to pay all amounts  then  due  in
respect of the Bonds.

    In Section 5.04 of the Loan Agreement, the Company has
agreed  to  indemnify  the  Trustee  and  any  predecessor
Trustee to the extent provided therein.

  X.15.         Notice of Events of Default.  The  Trustee
shall not be required to take notice, or be deemed to have
notice,  of  any  default or Event of Default  under  this
Indenture other than an Event of Default under clause  (a)
or  (b)  of  the first paragraph of Section  9.01  hereof,
unless  an  officer assigned by the Trustee to  administer
its   corporate  trust  business  has  been   specifically
notified in writing of such default or Event of Default by
Owners  of  at least 25% in principal amount of the  Bonds
then  Outstanding or by the Bank, the Tender Agent or  the
Remarketing Agent.  The Trustee may, however, at any time,
in  its  discretion,  require  of  the  Pollution  Control
Corporation and the Company full information and advice as
to the performance of any of the covenants, conditions and
agreements contained herein.

  X.16.         Action by Trustee.  The Trustee  shall  be
under  no obligation to take any action in respect of  any
default  or  Event  of  Default hereunder  or  toward  the
execution  or  enforcement of any  of  the  trusts  hereby
created, or to institute, appear in or defend any suit  or
other proceeding in connection therewith, unless requested
in writing so to do by Owners of at least 25% in principal
amount of the Bonds then Outstanding or the Bank, and,  if
in  its  opinion  such action may tend to  involve  it  in
expense or liability, unless furnished, from time to  time
as  often  as it may require, with security and  indemnity
satisfactory  to  it;  provided,  however,  that  no  such
security  or  indemnity  shall be required  prior  to  the
Trustee  taking  any  action  on  a  Security  Arrangement
(including  a  drawing on the Letter of Credit)  otherwise
required  by  the terms hereof, but the Trustee  shall  be
entitled  to  such security or indemnity thereafter.   The
foregoing  provisions are intended only for the protection
of  the  Trustee, and shall not affect any  discretion  or
power  given  by any provisions of this Indenture  to  the
Trustee to take action in respect of any default or  Event
of  Default without such notice or request from the Owners
of  the  Bonds  or the Bank, or without such  security  or
indemnity.

  X.17.        Good Faith Reliance.  The Trustee shall  be
protected  and  shall  incur no  liability  in  acting  or
proceeding  in  good  faith upon any  resolution,  notice,
telegram, telex, facsimile transmission, request, consent,
waiver, certificate, statement, affidavit, voucher,  bond,
requisition or other paper or document which it  shall  in
good  faith believe to be genuine and to have been  passed
or  signed by the proper board, body or person or to  have
been  prepared  and  furnished  pursuant  to  any  of  the
provisions  of  this Indenture or the Loan  Agreement,  or
upon  the  written  opinion  of  any  attorney,  engineer,
accountant or other expert believed by the Trustee  to  be
qualified  in  relation  to the subject  matter,  and  the
Trustee  shall  be under no duty to make any investigation
or  inquiry  as  to  any statements contained  or  matters
referred  to  in any such instrument, but may  accept  and
rely upon the same as conclusive evidence of the truth and
accuracy  of  such statements.  Neither the  Trustee,  the
Paying  Agent, any Co-Paying Agent, the Registrar nor  the
Tender Agent shall be bound to recognize any person as  an
Owner  of  a  Bond or to take any action  at  his  request
unless   the   ownership  of  such  Bond  is   proved   as
contemplated in Section 11.01 hereof.

  X.18.         Dealings in Bonds and with  the  Pollution
Control  Corporation and the Company.   The  Trustee,  the
Paying  Agent,  any  Co-Paying Agent, the  Registrar,  the
Tender  Agent or the Remarketing Agent, in its  individual
or  any other capacity, may in good faith buy, sell,  own,
hold  and  deal in any of the Bonds issued hereunder,  and
may  join in any action which any Owner of a Bond  may  be
entitled to take with like effect as if it did not act  in
any  capacity  hereunder.  The Trustee, the Paying  Agent,
any  Co-Paying Agent, the Registrar, the Tender  Agent  or
the  Remarketing  Agent, in its individual  or  any  other
capacity, either as principal or agent, may also engage in
or  be  interested  in any financial or other  transaction
with the Pollution Control Corporation or the Company, and
may act as depositary, trustee, or agent for any committee
or  body  of  Owners  of  Bonds secured  hereby  or  other
obligations of the Pollution Control Corporation as freely
as if it did not act in any capacity hereunder.

  X.19.        Allowance of Interest.  The Trustee may, but
shall not be obligated to, allow and credit interest  upon
any  moneys which it may at any time receive under any  of
the provisions of this Indenture, at such rate, if any, as
it  customarily allows upon similar funds of similar  size
and under similar conditions.  All interest allowed on any
such moneys shall be credited as provided in Articles  IV,
V and VI with respect to interest on investments.

  X.2   0.  Construction of Indenture.   The  Trustee  may
construe  any of the provisions of this Indenture  insofar
as  the  same  may appear to be ambiguous or  inconsistent
with  any other provision hereof, and any construction  of
any  such  provisions hereof by the Trustee in good  faith
shall be binding upon the Owners of the Bonds.

  X.21.         Resignation of Trustee.  The  Trustee  may
resign  and  be discharged of the trusts created  by  this
Indenture  by executing an instrument in writing resigning
such  trust  and specifying the date when such resignation
shall  take effect, and filing the same with the President
of  the Pollution Control Corporation, and with the Tender
Agent,  the Remarketing Agent, the Company and  the  Bank,
not  less  than  forty-five  (45)  days  before  the  date
specified  in such instrument when such resignation  shall
take  effect, and by giving notice of such resignation  by
Mail  to all Owners of Bonds.  Such resignation shall take
effect  on the later to occur of (i) the day specified  in
such  instrument and notice, unless previously a successor
Trustee shall have been appointed as hereinafter provided,
in   which  event  such  resignation  shall  take   effect
immediately upon the appointment of such successor Trustee
and (ii) the appointment of a successor Trustee.

    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 Pollution Control
Corporation  shall have delivered to the  Trustee  (i)  an
instrument appointing a successor Trustee, 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 in  accordance  with  Section
10.16,  the  Trustee shall be deemed to have  resigned  as
contemplated in this Section, the successor Trustee  shall
be  deemed  to have been appointed pursuant to  subsection
(b)  of Section 10.13 and such appointment shall be deemed
to  have  been accepted as contemplated in Section  10.16,
all  as  of  such date, and all other provisions  of  this
Article   X  shall  be  applicable  to  such  resignation,
appointment   and   acceptance  except   to   the   extent
inconsistent  with this paragraph.  The Pollution  Control
Corporation   shall   deliver  any  such   instrument   of
appointment at the direction of the Company.

  X.22.         Removal  of Trustee.  The Trustee  may  be
removed at any time by filing with the Trustee so removed,
and  with  the Pollution Control Corporation,  the  Tender
Agent,   the   Remarketing  Agent  and  the  Company,   an
instrument   or  instruments  in  writing,  appointing   a
successor,  or  an instrument or instruments  in  writing,
consenting  to  the  appointment by the Pollution  Control
Corporation  (at  the  direction  of  the  Company)  of  a
successor  and accompanied by an instrument of appointment
by  the Pollution Control Corporation (at the direction of
the  Company) of such successor, and in any event executed
by  Owners of not less than a majority in principal amount
of  the Bonds then Outstanding, such filing to be made  by
any Owner of a Bond or his duly authorized attorney.


  X.23.         Appointment of Successor Trustee.  (a)  In
case  at  any  time the Trustee shall be  removed,  or  be
dissolved,  or if its property or affairs shall  be  taken
under  the  control  of  any state  or  federal  court  or
administrative  body because of insolvency or  bankruptcy,
or  for  any other reason, then a vacancy shall  forthwith
and ipso facto exist and a successor may be appointed, and
in  case at any time the Trustee shall resign or be deemed
to  have  resigned, then a successor may be appointed,  by
filing  with the Pollution Control Corporation, the Tender
Agent, the Remarketing Agent and the Company an instrument
in  writing appointing such successor Trustee executed  by
Owners of not less than a majority in principal amount  of
Bonds  then  Outstanding, together with, so  long  as  the
Letter of Credit shall be in effect and no drawing on  the
Letter  of  Credit  shall  have been,  and  shall  remain,
wrongfully  dishonored, a consent  of  the  Bank  to  such
appointment   (such   consent  not  to   be   unreasonably
withheld).   Copies of such instrument shall  be  promptly
delivered  by  the  Pollution Control Corporation  to  the
predecessor Trustee, to the Trustee so appointed  and  the
Company.

  (a)    Until a successor Trustee shall be appointed by the
Owners  of  the Bonds as herein authorized, the  Pollution
Control Corporation, shall appoint a successor Trustee  as
directed  by  the Company with, so long as the  Letter  of
Credit shall be in effect and no drawing on the Letter  of
Credit  shall have been, and shall remain, the consent  of
the  Bank  (such consent not to be unreasonably withheld).
After   any   appointment   by   the   Pollution   Control
Corporation, it shall cause notice of such appointment  to
be  given by Mail to all Owners of Bonds.  Any new Trustee
so  appointed  by the Pollution Control Corporation  shall
immediately  and  without further act be superseded  by  a
Trustee appointed by the Owners of the Bonds in the manner
above provided.

  (b)     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.

  X.24.        Qualifications of Successor Trustee.  Every
successor  Trustee (a) shall be a bank  or  trust  company
duly organized under the laws of the United States or  any
state  or  territory thereof authorized by law to  perform
all  the duties imposed upon it by this Indenture and  (b)
shall  have (or the parent holding company of which  shall
have)  a  combined  capital stock, surplus  and  undivided
profits  of at least $100,000,000 if there can be located,
with  reasonable effort, such an institution  willing  and
able  to  accept  the  trust on reasonable  and  customary
terms.

  X.25.         Judicial Appointment of Successor Trustee.
In  case  at  any  time the Trustee shall  resign  and  no
appointment of a successor Trustee shall be made  pursuant
to the foregoing provisions of this Article X prior to the
date  specified in the notice of resignation as  the  date
when  such  resignation is to take  effect,  the  retiring
Trustee  may  forthwith  apply to  a  court  of  competent
jurisdiction  for the appointment of a successor  Trustee.
If  no  appointment of a successor Trustee shall  be  made
pursuant  to  the foregoing provisions of this  Article  X
within  six months after a vacancy shall have occurred  in
the  office of Trustee, any Owner of a Bond may  apply  to
any court of competent jurisdiction to appoint a successor
Trustee.  Such court may thereupon, after such notice,  if
any,  as  it  may  deem  proper and prescribe,  appoint  a
successor Trustee.

  X.26.         Acceptance of Trusts by Successor Trustee.
Any  successor Trustee appointed hereunder shall  execute,
acknowledge   and   deliver  to  the   Pollution   Control
Corporation   an  instrument  accepting  such  appointment
hereunder,  and thereupon such successor Trustee,  without
any  further  act, deed or conveyance, shall  become  duly
vested  with  all  the estates, property, rights,  powers,
trusts, duties and obligations of its predecessor  in  the
trust  hereunder, with like effect as if originally  named
Trustee  herein.   Upon  request  of  such  Trustee,  such
predecessor  Trustee and the Pollution Control Corporation
shall  execute  and deliver an instrument transferring  to
such  successor Trustee all the estates, property, rights,
powers  and  trusts hereunder of such predecessor  Trustee
and,  subject  to the provisions of Section 10.04  hereof,
such  predecessor Trustee shall pay over to the  successor
Trustee all moneys and other assets at the time held by it
hereunder.

  X.27.        Successor by Merger or Consolidation.   Any
corporation   or  association  into  which   any   Trustee
hereunder may be merged or converted or with which it  may
be   consolidated,  or  any  corporation  or   association
resulting  from any merger or consolidation to  which  any
Trustee hereunder shall be a party, shall be the successor
Trustee  under  this Indenture, without the  execution  or
filing of any paper or any further act on the part of  the
parties hereto, anything in this Indenture to the contrary
notwithstanding.

If,  at  the time any such successor to the Trustee  shall
succeed  to the trusts created by this Indenture,  any  of
the Bonds shall have been authenticated but not delivered,
such  successor  Trustee  may  adopt  the  certificate  of
authentication of any predecessor Trustee and deliver such
Bonds  so authenticated; and if at that time, any  of  the
Bonds  shall  not have been authenticated, such  successor
Trustee may authenticate such Bonds either in the name  of
any  such  predecessor hereunder or in the  name  of  such
successor;  and,  in all such cases, such  certificate  of
authentication  shall  have the full  force  which  it  is
anywhere  in the Bonds or in this Indenture provided  that
the  certificate  of authentication of the  Trustee  shall
have;  provided,  however, that the  right  to  adopt  the
certificate  of authentication of any predecessor  Trustee
or  to  authenticate Bonds in the name of any  predecessor
Trustee shall apply only to its successor or successors by
merger, conversion or consolidation.

  X.28.        Standard of Care.  Notwithstanding any other
provisions  of  this Article X, the Trustee shall,  during
the  existence of an Event of Default of which the Trustee
has  actual notice, exercise such of the rights and powers
vested in it by this Indenture and use the same degree  of
skill  and  care in their exercise as a prudent man  would
use and exercise under the circumstances in the conduct of
his own affairs.

  X.29.         Notice  to  Owners of Bonds  of  Event  of
Default.   If  an  Event of Default occurs  of  which  the
Trustee by Section 10.05 hereof is required to take notice
and  deemed to have notice, or any other Event of  Default
occurs of which the Trustee has been specifically notified
in  accordance  with Section 10.05 hereof,  and  any  such
Event  of  Default shall continue for at  least  two  days
after  the Trustee acquires actual notice thereof,  unless
the  Trustee  shall  have theretofore given  a  notice  of
acceleration pursuant to Section 9.01 hereof, the  Trustee
shall  give  notice  thereof  to  the  Tender  Agent,  the
Remarketing Agent and the Bank and give Notice by Mail  to
all Owners of Outstanding Bonds.

  X.3   0.  Intervention in Litigation  of  the  Pollution
Control Corporation.  In any judicial proceeding to  which
the Pollution Control Corporation is a party and which  in
the  opinion  of  the  Trustee  and  its  counsel  has   a
substantial  bearing on the interests  of  the  Owners  of
Bonds,  the Trustee may intervene on behalf of the  Owners
of   the  Bonds  and  shall,  upon  receipt  of  indemnity
satisfactory  to  it,  do so if requested  in  writing  by
Owners  of  at least 25% in principal amount of the  Bonds
then   Outstanding  if  permitted  by  the  court   having
jurisdiction in the premises.

  X.31.          Paying  Agent;  Co-Paying  Agents.    The
Pollution Control Corporation shall, with the approval  of
the  Company, appoint the Paying Agent for the  Bonds  and
may at any time or from time to time, with the approval of
the  Company, appoint one or more Co-Paying Agents for the
Bonds,  subject  to the conditions set  forth  in  Section
10.22  hereof.  The Paying Agent and each Co-Paying  Agent
shall  designate to the Trustee its Principal  Office  and
signify  its  acceptance  of the  duties  and  obligations
imposed  upon  it  hereunder by a  written  instrument  of
acceptance  delivered to the Pollution Control Corporation
and  the  Trustee in which such Paying Agent or  Co-Paying
Agent will agree, particularly:

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

     (b)    to  keep  such books and records as  shall  be
  consistent with prudent industry practice, to make  such
  books  and  records  available  for  inspection  by  the
  Pollution Control Corporation, the Trustee and the Company
  at  all reasonable times and, in the case of a Co-Paying
  Agent,  to  promptly furnish copies of  such  books  and
  records to the Paying Agent; and

     (c)   in the case of a Co-Paying Agent, upon the request
  of  the Paying Agent, to forthwith deliver to the Paying
  Agent all sums so held in trust by such Co-Paying Agent.

    The Pollution Control Corporation shall cooperate with
the  Trustee  and  the  Company  to  cause  the  necessary
arrangements  to  be  made and to be thereafter  continued
whereby  funds  derived  from  the  sources  specified  in
Sections  4.03 and 4.04 hereof will be made  available  to
the  Paying Agent and each Co-Paying Agent for the payment
when  due  of  the  principal of,  premium,  if  any,  and
interest on the Bonds.

  X.32.        Qualifications of Paying Agent and Co-Paying
Agents;  Resignation; Removal.  The Paying Agent  and  any
Co-Paying Agent shall be a corporation or association duly
organized  under the laws of the United States of  America
or  any  state  or  territory thereof, having  a  combined
capital  stock, surplus and undivided profits of at  least
$15,000,000  and  authorized by law  to  perform  all  the
duties  imposed upon it by this Indenture; provided  that,
if  the  Bonds  shall  be rated by  Moody's  and  if  such
corporation shall not be a bank or trust company, its long
term  debt  or  that of its parent shall  have  a  Moody's
rating  not lower than Baa3 or the equivalent thereof  and
its  short-term debt or that of its parent  shall  have  a
Moody's  rating  not  lower than  P-3  or  the  equivalent
thereof  unless,  in either case, there  shall  have  been
furnished  to  the  Pollution  Control  Corporation,   the
Trustee  and the Company written evidence from Moody's  to
the  effect  that  the appointment of the proposed  Paying
Agent or Co-Paying Agent will not, by itself, result in  a
reduction  or withdrawal of its ratings then in effect  on
the  Bonds.  The Paying Agent and any Co-Paying Agent  may
at  any  time resign and be discharged of the  duties  and
obligations created by this Indenture by giving  at  least
sixty   (60)   days'  notice  to  the  Pollution   Control
Corporation,  the  Company and the  Trustee.   The  Paying
Agent  and any Co-Paying Agent may be removed at any time,
at  the direction of the Company, by an instrument, signed
by  the  Pollution  Control Corporation,  filed  with  the
Paying Agent or such Co-Paying Agent, as the case may  be,
and with the Trustee.

    In  the  event  of the resignation or removal  of  the
Paying  Agent or any Co-Paying Agent, the Paying Agent  or
such  Co-Paying Agent, as the case may be, shall pay over,
assign  and deliver any moneys held by it in such capacity
to  its  successor  or, if there be no successor,  to  the
Trustee.

    In  the  event that the Pollution Control  Corporation
shall fail to appoint a Paying Agent hereunder, or in  the
event that the Paying Agent shall resign or be removed, or
be  dissolved, or if the property or affairs of the Paying
Agent  shall  be taken under the control of any  state  or
federal court or administrative body because of bankruptcy
or  insolvency, or for any other reason, and the Pollution
Control Corporation shall not have appointed its successor
as Paying Agent, the Trustee shall ipso facto be deemed to
be  the  Paying  Agent for all purposes of this  Indenture
until the appointment by the Pollution Control Corporation
of the Paying Agent or successor Paying Agent, as the case
may be.

    Upon the appointment of a successor Paying Agent,  the
Trustee shall give notice thereof by Mail to all Owners of
Bonds.

  X.33.        Registrar.  The Pollution Control Corporation
shall,  with  the  approval of the  Company,  appoint  the
Registrar  for  the Bonds, subject to the  conditions  set
forth  in  Section  10.24  hereof.   The  Registrar  shall
designate to the Trustee its Principal Office and  signify
its acceptance of the duties imposed upon it hereunder  by
a  written  instrument  of  acceptance  delivered  to  the
Pollution  Control Corporation and the  Trustee  in  which
such  Registrar  will agree, particularly,  to  keep  such
books  and  records  as shall be consistent  with  prudent
industry  practice  and  to make such  books  and  records
available   for   inspection  by  the  Pollution   Control
Corporation, the Trustee and the Company at all reasonable
times.

    The Pollution Control Corporation shall cooperate with
the  Trustee  and  the  Company  to  cause  the  necessary
arrangements  to  be  made and to be thereafter  continued
whereby   Bonds,   executed  by  the   Pollution   Control
Corporation  and  authenticated by the Trustee,  shall  be
made available for exchange, registration and registration
of transfer at the Principal Office of the Registrar.  The
Pollution  Control  Corporation shall cooperate  with  the
Trustee,  the  Registrar  and the  Company  to  cause  the
necessary arrangements to be made and thereafter continued
whereby the Paying Agent, any Co-Paying Agent, the  Tender
Agent  and  the Remarketing Agent shall be furnished  such
records and other information, at such times, as shall  be
required to enable the Paying Agent, such Co-Paying Agent,
the  Tender Agent and the Remarketing Agent to perform the
duties and obligations imposed upon them hereunder.

  X.34.         Qualifications of Registrar;  Resignation;
Removal.    The  Registrar  shall  be  a  corporation   or
association  duly organized under the laws of  the  United
States  of  America  or  any state or  territory  thereof,
having  a  combined capital stock, surplus  and  undivided
profits of at least $15,000,000 and authorized by  law  to
perform  all the duties imposed upon it by this Indenture.
The Registrar may at any time resign and be discharged  of
the  duties  and obligations created by this Indenture  by
giving  at  least sixty (60) days' notice to the Pollution
Control  Corporation, the Trustee and  the  Company.   The
Registrar may be removed at any time, at the direction  of
the  Company,  by  an instrument signed by  the  Pollution
Control  Corporation  filed with  the  Registrar  and  the
Trustee.

    In  the  event  of the resignation or removal  of  the
Registrar, the Registrar shall deliver any Bonds  held  by
it  in  such capacity to its successor or, if there be  no
successor, to the Trustee.

    In  the  event that the Pollution Control  Corporation
shall  fail to appoint a Registrar hereunder,  or  in  the
event that the Registrar shall resign or be removed, or be
dissolved, or if the property or affairs of the  Registrar
shall  be taken under the control of any state or  federal
court  or  administrative body because  of  bankruptcy  or
insolvency,  or  for any other reason, and  the  Pollution
Control Corporation shall not have appointed its successor
as Registrar, the Trustee shall ipso facto be deemed to be
the Registrar for all purposes of this Indenture until the
appointment  by the Pollution Control Corporation  of  the
Registrar or successor Registrar, as the case may be.

    Upon  the  appointment of a successor  Registrar,  the
Trustee shall give notice thereof by Mail to all Owners of
Bonds.

  X.35.        Several Capacities.  Anything herein to the
contrary  notwithstanding,  the  same  entity  may   serve
hereunder  as the Trustee, the Paying Agent or a Co-Paying
Agent, the Registrar, the Tender Agent and the Remarketing
Agent,  and in any combination of such capacities  to  the
extent permitted by law.


XI   EXECUTION OF INSTRUMENTS BY OWNERS OF BONDS AND
               PROOF OF OWNERSHIP OF BONDS

  XI.11.       Execution of Instruments; Proof of Ownership.
Any  request,  direction, consent or other  instrument  in
writing,  whether  or not required or  permitted  by  this
Indenture to be signed or executed by Owners of the Bonds,
may  be in any number of concurrent instruments of similar
tenor and may be signed or executed by Owners of the Bonds
or  by  an  agent appointed by an instrument  in  writing.
Proof  of the execution of any such instrument and of  the
ownership of Bonds shall be sufficient for any purpose  of
this  Indenture and shall be conclusive in  favor  of  the
Trustee  with regard to any action taken by it under  such
instrument if made in the following manner:

     (a)   The fact and date of the execution by any person of
  any such instrument may be proved by the certificate  of
  any officer in any jurisdiction who, by the laws thereof,
  has   power   to   take  acknowledgments   within   such
  jurisdiction, to the effect that the person signing such
  instrument acknowledged before him the execution thereof,
  or by an affidavit of a witness to such execution.

     (b)   The ownership or former ownership of Bonds shall be
  proved by the registration books kept under the provisions
  of Section 2.09 hereof.

   Nothing contained in this Article XI shall be construed
as  limiting the Trustee to such proof, it being  intended
that  the Trustee may accept any other evidence of matters
herein  stated which it may deem sufficient.  Any  request
or  consent of any Owner of a Bond shall bind every future
Owner of the same Bond or any Bond or Bonds issued in lieu
thereof in respect of anything done by the Trustee or  the
Pollution Control Corporation in pursuance of such request
or consent.


XII  MODIFICATION OF THIS INDENTURE AND THE LOAN AGREEMENT

  XII.11.      Limitations.  Neither this Indenture nor the
Loan Agreement shall be modified or amended in any respect
subsequent to the original issuance of the Bonds except as
provided  in  and in accordance with and  subject  to  the

  denominations and similar amendments and modifications of
  a technical nature;

  second paragraph of Section 12.06 hereof or which may be
  necessary,   desirable  or  appropriate  in   connection
  therewith (including without limitation the insertion of

  purposes thereof; provided, however, that anything in this
  clause  (f)  of Section 12.02 or Section  12.06  to  the
  contrary    notwithstanding,   no   such   modification,
  alteration, amendment or supplement to this Indenture or
  the Loan Agreement shall render the Receipts and Revenues
  of  the  Pollution  Control Corporation  from  the  Loan
  Agreement (as such term is defined in this Indenture  as
  originally executed and delivered or as modified, altered,
  amended or supplemented) insufficient to pay the principal
  of and premium, if any, and interest on the Bonds;

     (g)   to modify, alter, supplement or amend this Indenture

  Bonds are evidenced by certificates;

     (i)   to provide a different method for the determination
  of the Daily Rate, Weekly Rate, Monthly Rate, Term Rate,
  Flexible Rates or the Fixed Rate if the method set forth
  herein is unavailable or unrealistic in the marketplace,
  but  only after notice thereof shall have been given  by
  Mail to all Owners of the Bonds;

     (j)   to modify, alter, amend or supplement this Indenture
  in  any other respect which is not materially adverse to
  the Owners and which does not involve a change described
  in  clause (i), (ii), (iii) or (iv) of Section  12.03(a)
  hereof;

     (k)   to provide any additional procedures, covenants or
  agreements necessary or desirable to maintain  the  tax-

  otherwise be described in Section 12.03 hereof,  if  the
  effective date of such amendment is a date on which  all
  Bonds affected thereby are subject to mandatory tender for
  purchase pursuant to Section 2.02(h) or if Notice by Mail
  of  the  proposed amendment is given to  Owners  of  the
  affected Bonds at least 30 days before the effective date
  thereof and, on or before such effective date, such Owners
  have the right to demand purchase of their Bonds pursuant

    Before  the  Pollution  Control  Corporation  and  the
Trustee   shall  enter  into  any  Supplemental  Indenture

delivered  to  the  Trustee an  opinion  of  Bond  Counsel
stating that such Supplemental Indenture is authorized  or
permitted  by  this Indenture and the Act,  complies  with
their  respective  terms, will,  upon  the  execution  and
delivery  thereof, be valid and binding upon the Pollution
Control Corporation in accordance with its terms and  will
not, in and of itself, adversely affect the exclusion from
gross  income for federal tax purposes of the interest  on
the Bonds.

  XII.13.       Supplemental Indentures  with  Consent  of
Owners.  (a) Except for any Supplemental Indenture entered
into  pursuant  to Section 12.02 hereof,  subject  to  the
terms  and provisions contained in this Section 12.03  and
Section 12.05 and not otherwise, Owners of not less than a
majority  in aggregate principal amount of the Bonds  then
Outstanding  which  would  be adversely  affected  thereby
shall  have the right from time to time to consent to  and
approve  the  execution  and  delivery  by  the  Pollution
Control  Corporation and the Trustee of  any  Supplemental
Indenture  deemed necessary or desirable by the  Pollution
Control   Corporation  for  the  purposes  of   modifying,
altering,  amending, supplementing or rescinding,  in  any
particular,  any of the terms or provisions  contained  in
this  Indenture; provided, however, that, unless  approved
in writing by the Owners of all the Bonds then Outstanding
which  would be adversely affected thereby, nothing herein
contained shall permit, or be construed as permitting, (i)
a  change in the times, amounts or currency of payment  of
the  principal of or premium, if any, or interest  on  any
Outstanding Bond, a change in the purchase price  or  time
of  purchase  of  Bonds  tendered pursuant  to  the  terms
hereof,  a reduction in the principal amount or redemption
price of any Outstanding Bond or a change in the method of
determining   the  rate  of  interest  thereon,   or   any
impairment of the right of any Owner to institute suit for
the  payment of any Bond owned by it, or (ii) the creation
of  a claim or lien upon, or a pledge of, the Receipts and
Revenues  of  the Pollution Control Corporation  from  the
Loan  Agreement ranking prior to or on a parity  with  the
claim, lien or pledge created by this Indenture (except as
referred  to  in  Section  10.04  hereof),  or   (iii)   a
preference or priority of any Bond or Bonds over any other
Bond  or  Bonds,  or  (iv) a reduction  in  the  aggregate
principal  amount of Bonds the consent of  the  Owners  of
which  is required for any such Supplemental Indenture  or
which  is  required, under Section 12.07 hereof,  for  any
modification, alteration, amendment or supplement  to  the
Loan Agreement.

  (a)    If  at any time the Pollution Control Corporation
shall  request the Trustee to enter into any  Supplemental
Indenture  for any of the purposes of this Section  12.03,
the   Trustee   shall  cause  notice   of   the   proposed
Supplemental Indenture to be given by Mail to  all  Owners
of  Outstanding Bonds and to the Bank.  Such notice  shall
briefly  set forth the nature of the proposed Supplemental
Indenture and shall state that a copy thereof is  on  file
at  the Principal Office of the Trustee for inspection  by
all Owners of Bonds and by the Bank.

  (b)   Within two years after the date of the first mailing
of  such notice, the Pollution Control Corporation and the
Trustee  may  enter  into such Supplemental  Indenture  in
substantially  the form described in such notice  only  if
there  shall have first been delivered to the Trustee  (i)
the  required consents, in writing, of Owners of Bonds and
(ii)   an  opinion  of  Bond  Counsel  stating  that  such
Supplemental Indenture is authorized or permitted by  this
Indenture  and  the  Act, complies with  their  respective
terms  and, upon the execution and delivery thereof,  will
be   valid   and   binding  upon  the  Pollution   Control
Corporation  in  accordance with its terms  and  will  not
adversely   affect  the  exemption  from  federal   income
taxation of interest on the Bonds.

  (c)   If Owners of not less than the percentage of Bonds
required by this Section 12.03 shall have consented to and
approved  the  execution and delivery  thereof  as  herein
provided, no Owner shall have any right to object  to  the
execution and delivery of such Supplemental Indenture,  or
to  object  to  any of the terms and provisions  contained
therein  or  the operation thereof, or in  any  manner  to
question  the  propriety  of the  execution  and  delivery
thereof,  or  to enjoin or restrain the Pollution  Control
Corporation  or the Trustee from executing and  delivering
the  same  or  from  taking any  action  pursuant  to  the
provisions thereof.

  (d)    Subject to the terms and provisions contained  in
this subsection (e) of Section 12.03 and in Section 12.05,
the  Owners of all the Bonds at any time Outstanding shall
have the right, and the Pollution Control Corporation  and
the  Trustee  by  their  execution and  delivery  of  this
Indenture  hereby expressly confer upon  such  Owners  the
right to modify, alter, amend or supplement this Indenture
in any respect, including without limitation in respect of
the matters described in clauses (i), (ii), (iii) and (iv)
of the proviso contained in subsection (a) of this Section
12.03, by delivering to the Pollution Control Corporation,
the  Trustee  and  the  Company a  written  instrument  or
instruments,  executed  by or on behalf  of  such  Owners,
containing  a  form of Supplemental Indenture  which  sets
forth  such  modifications,  alterations,  amendments  and
supplements, and, upon the expiration of a thirty (30) day
period  commencing  on  the date of such  delivery  during
which no notice of objection shall have been delivered  by
the  Pollution  Control Corporation, the  Trustee  or  the
Company  to  such Owners at an address specified  in  such
written  instrument, such Supplemental Indenture shall  be
deemed  to  have  been  approved  and  confirmed  by   the
Pollution Control Corporation and the Trustee, to the same
extent  as  if  actually executed  and  delivered  by  the
Pollution Control Corporation and the Trustee, and to have
been  approved  by  the  Company,  and  such  Supplemental
Indenture  shall thereupon become and be for all  purposes
in  full  force and effect without further action  by  the
Pollution Control Corporation, the Trustee or the Company.
The  foregoing  provisions are, however,  subject  to  the
following conditions:

     (i)   no such Supplemental Indenture shall in any way
  affect  the  limited  nature of the obligations  of  the
  Pollution Control Corporation under this Indenture as set
  forth in Sections 2.06 and 7.01 hereof or shall adversely
  affect any of its rights hereunder;

     (ii)  no such Supplemental Indenture shall be to  the
  prejudice of the Paying Agent or any Co-Paying Agent, the
  Registrar, the Tender Agent or the Remarketing Agent; and

     (iii)       there  shall have been delivered  to  the
  Pollution Control Corporation, the Trustee and the Company
  an opinion of Bond Counsel stating that such Supplemental
  Indenture is authorized or permitted by this Indenture and
  the Act, complies with their respective terms, will, upon
  the expiration of the aforesaid thirty (30) day period, be
  valid and binding upon the Pollution Control Corporation
  in accordance with its terms and will not adversely affect
  the  exclusion of the interest on the Bonds  from  gross
  income for federal income tax purposes.

  XII.14.      Effect of Supplemental Indenture.  Upon the
execution  and  delivery  of  any  Supplemental  Indenture
pursuant  to the provisions of this Article XII (including
the  becoming  effective  of a Supplemental  Indenture  as
provided in Section 12.03(e) hereof), this Indenture shall
be,  and  be  deemed to be, modified, altered, amended  or
supplemented  in accordance therewith, and the  respective
rights, duties and obligations under this Indenture of the
Pollution  Control Corporation, the Trustee and Owners  of
all Bonds then Outstanding shall thereafter be determined,
exercised and enforced under this Indenture subject in all
respects  to  such modifications, alterations,  amendments
and supplements.

  XII.15.       Consent of the Company and  Obligor  under
Security  Arrangement.  Anything herein  to  the  contrary
notwithstanding,  any  Supplemental Indenture  under  this
Article  XII which affects any rights, powers,  agreements
or  obligations of the Company under the Loan Agreement or
of the obligor under any Security Arrangement, or requires
a   revision  of  the  Loan  Agreement  or  any   Security
Arrangement, shall not become effective unless  and  until
the  Company  or such obligor, as the case may  be,  shall
have consented to such Supplemental Indenture.

  XII.16.      Amendment of Loan Agreement without Consent
of Owners.  Without the consent of or notice to the Owners
of  the Bonds, the Pollution Control Corporation may enter
into any Supplemental Loan Agreement, and the Trustee  may
consent  thereto, as may be required (a) by the provisions
of  the  Loan  Agreement and this Indenture, (b)  for  the
purpose   of   curing   any   formal   defect,   omission,
inconsistency  or ambiguity therein, (c)  to  provide  any
additional  procedures, covenants or agreements  necessary
or desirable to maintain the tax-exempt status of interest
on  the  Bonds, or (d) in connection with any other change
therein  which is not materially adverse to the Owners  of
the  Bonds.  A revision of Exhibit A to the Loan Agreement
pursuant  to Section 3.03 thereof, shall not be  deemed  a
Supplemental   Loan  Agreement  for   purposes   of   this
Indenture.

   In addition to the foregoing, without the consent of or
notice  to the Owners of the Bonds, the Pollution  Control
Corporation  may  modify, alter, amend or  supplement  the
Loan Agreement, and the Trustee shall consent thereto,  in
any  and  all respects necessary, desirable or appropriate
in  connection  with the Termination, in  accordance  with
Section 6.07(c) of the Loan Agreement, or any provision of
any  Security Arrangement, including, without  limitation,
to  provide that the obligation of the Company to make (a)
the  Loan  Payments, (b) that portion of the Loan Payments
equal  to  the principal amount of the Bonds, or (c)  that
portion of the Loan Payments equal to the principal amount
of  the Bonds plus all or any portion of the Loan Payments
equal  to the premium, if any, and interest on the  Bonds,
shall  be  either evidenced or secured by  First  Mortgage
Bonds  issued and delivered to the Trustee.  In connection
with  any  such  modification,  alteration,  amendment  or
supplement  made  in connection with the delivery  to  the
Trustee  of  First Mortgage Bonds, (a) the First  Mortgage
Bonds  to be delivered shall be equal in principal  amount
to  the Bonds then Outstanding, but may be delivered  from
time  to time in principal amounts determined by reference
to  the  amounts remaining on deposit in the  Construction
Fund  or  the Capital Account maintained therein, (b)  the
First Mortgage Bonds shall (i) bear no interest, (ii) bear
interest at a fixed rate or (iii) bear interest at a  rate
equal  to  the  rate of interest borne by  the  Bonds,  as
determined  by  the Company, (c) the First Mortgage  Bonds
shall  be voted, and consents shall be given with  respect
thereto,  proportionately with what the Trustee reasonably
believes will be the vote or consent of the holders of all
other  bonds outstanding under the Company Mortgage  which
vote   or  consent,  or  otherwise  as  provided  in  such
modification, alteration, amendment or supplement, (d) the
First Mortgage Bonds shall be pledged and assigned by  the
Pollution  Control Corporation to the Trustee as  part  of
the  Trust Estate and may be pledged and assigned  by  the
Pollution Control Corporation, secondarily and subject  to
the  rights of the Trustee therein, to the obligor on  any
other Security Arrangement as collateral security for  the
obligations of the Company to such obligor, and (e) to the
extent  that  the First Mortgage Bonds shall evidence  the
obligation  of the Company to make the Loan Payments,  the
obligation of the Company contained in the Loan  Agreement
to make the Loan Payments may be extinguished.

    The right of the Pollution Control Corporation to make
any  modification, alteration, amendment or supplement  to
the  Loan  Agreement  pursuant to the preceding  paragraph
shall  include  the  right  to  make  any  and  all   such
additional   modifications,  alterations,  amendments   or
supplements  to  the Loan Agreement as may  be  necessary,
desirable  or  appropriate to carry out the  purposes  set
forth in such paragraph.

    Before  the Pollution Control Corporation shall  enter
into,  and  the Trustee shall consent to, any Supplemental
Loan Agreement pursuant to this Section 12.06, there shall
have  been  delivered to the Trustee an  opinion  of  Bond
Counsel  stating that such Supplemental Loan Agreement  is
authorized  or permitted by this Indenture  and  the  Act,
complies  with  their  respective terms,  will,  upon  the
execution and delivery thereof, be valid and binding  upon
the  Pollution  Control Corporation  and  the  Company  in
accordance with its terms and will not, in and of  itself,
adversely  affect  the  exclusion from  gross  income  for
federal tax purposes of interest on the Bonds.

  XII.17.      Amendment of Loan Agreement with Consent of
Owners.    Except   in  the  case  of  Supplemental   Loan
Agreements  referred  to  in  Section  12.06  hereof,  the
Pollution  Control Corporation shall not enter  into,  and
the  Trustee  shall not consent to, any Supplemental  Loan
Agreement without the written approval or consent  of  the
Owners  of not less than a majority in aggregate principal
amount  of  the  Bonds  then Outstanding  which  would  be
adversely affected thereby, given and procured as provided
in  Section 12.03 hereof; provided, however, that,  unless
approved  in  writing  by the Owners  of  all  Bonds  then
Outstanding  which  would be adversely  affected  thereby,
nothing herein contained shall permit, or be construed  as
permitting,  a  change in the obligations of  the  Company
under  Section 5.01 of the Loan Agreement or a  change  in
the  obligations of the Company under Section 10.01(a)  of
the  Loan Agreement.  If at any time the Pollution Control
Corporation  or the Company shall request the  consent  of
the   Trustee  to  any  such  proposed  Supplemental  Loan
Agreement, the Trustee shall cause notice of such proposed
Supplemental Loan Agreement to be given in the same manner
as  provided  by  Section  12.03 hereof  with  respect  to
Supplemental  Indentures.  Such notice shall  briefly  set
forth  the  nature  of  such  proposed  Supplemental  Loan
Agreement  and  shall state that copies of the  instrument
embodying the same are on file at the Principal Office  of
the  Trustee for inspection by all Owners of the Bonds and
by  the Bank.  The Pollution Control Corporation may enter
into,  and  the Trustee may consent to, any such  proposed
Supplemental   Loan   Agreement  subject   to   the   same
conditions,  and  with  the same effect,  as  provided  by
Section   12.03   hereof  with  respect  to   Supplemental
Indentures.


XIII  TENDER  AGENT; REMARKETING AGENT;  PURCHASE  AND  RE
MARKETING OF BONDS

  XIII.11.     Tender Agent.  Subject to the conditions set
forth  in Section 13.02 hereof, the Tender Agent shall  be
appointed   by  the  Company.   The  Tender  Agent   shall
designate  its Principal Office and signify its acceptance
of the duties and obligations imposed upon it hereunder by
a  written  instrument  of  acceptance  delivered  to  the
Pollution   Control   Corporation,   the   Trustee,    the
Remarketing Agent, the Company and the Bank in  which  the
Tender Agent will agree, particularly:

     (a)    to hold all Bonds delivered to it for purchase
  hereunder  in  trust for the benefit of  the  respective
  Owners  which shall have so delivered such  Bonds  until
  moneys representing the purchase price of such Bonds shall
  have  been delivered to or for the account of or to  the
  order of such Owners;

     (b)   to hold all moneys delivered to it hereunder for the
  purchase of Bonds, other than moneys delivered to it  by
  the Company during the term of a Security Arrangement on
  which the Company shall not be the obligor, as agent and
  bailee of, and in escrow for the benefit of, the person or
  entity which shall have so delivered such moneys until the
  Bonds  to be purchased with such moneys shall have  been
  delivered to or for the account of such person or entity;

     (c)   to hold all moneys delivered to it by the Company
  for the purchase of Bonds in trust for the benefit of the
  Owners or former Owners who shall deliver Bonds to it for
  purchase until the Bonds purchased with such moneys shall
  have been delivered to or for the account of the Company;
  provided, however, that if the Bonds shall at  any  time
  become due and payable, the Tender Agent shall cause such
  moneys  (other  than  moneys held  pursuant  to  Section
  13.03(c) hereof) to be deposited into the Bond Fund;

     (d)   to hold Bonds for the account of the Company as and
  to  the  extent directed by the Bank as contemplated  by
  Section 13.07(c) hereof, such Bonds to be released to or
  upon the order of the Company upon receipt by the Tender
  Agent from the Bank of a written notice to the effect that
  such  Bonds  are released from any security interest  in
  favor of the Bank, the Letter of Credit is reinstated in
  full and that the Trustee is entitled to draw under  the
  Security Arrangement, to pay (i) principal of the  Bonds
  and the portion of purchase price equal to principal and
  (ii)  interest on the Bonds and the portion of  purchase
  price  equal to accrued interest, amounts equal  to  the
  amounts that could be drawn under a Security Arrangement
  if   the  drawing  made  to  purchase  such  Bonds  were
  disregarded (it being understood that, if so requested by
  the  Bank, the Tender Agent shall hold such Bonds in its
  capacity as custodian or collateral agent for the  Bank,
  subject  to any security interest of the Bank  therein);
  and, in the event of a redemption of any of such Bonds or
  the  acceleration of all Outstanding Bonds, to  hold  in
  trust moneys delivered to the Tender Agent in payment of
  the Bonds so held by it and to turn such moneys over  to
  the Bank to the extent of the amount specified by the Bank
  to the Tender Agent as the aggregate amount then owed by
  the Company to the Bank under the Reimbursement Agreement
  in respect of drawings under the Security Arrangement and
  interest thereon, any balance to be turned over  to  the
  Company;

     (e)   to give the notice specified in Section 2.10 hereof
  to the Owners of the Bonds; and

     (f)    to  keep  such books and records as  shall  be
  consistent with prudent industry practice and to make such
  books  and  records  available  for  inspection  by  the
  Pollution Control Corporation, the Trustee, the  Company
  and the Remarketing Agent at all reasonable times.

    The Pollution Control Corporation shall cooperate with
the Trustee, the Registrar, the Company, the Tender Agent,
the  Remarketing Agent and the Bank to cause the necessary
arrangements  to  be  made and to be thereafter  continued
whereby funds from the sources specified herein and in the
Loan Agreement will be made available for the purchase  of
Bonds  delivered  to the Principal Office  of  the  Tender
Agent for purchase in accordance with Section 2.02 hereof,
and  to otherwise enable the Tender Agent to carry out its
duties hereunder.

  XIII.12.      Qualifications of Tender Agent; Resignation;
Removal.   The  Tender Agent shall be a  corporation  duly
organized  under the laws of the United States of  America
or  any  state  or  territory thereof, having  a  combined
capital  stock, surplus and undivided profits of at  least
$100,000,000  and  authorized by law to  perform  all  the
duties  imposed upon it by this Indenture; provided  that,
if  the  Bonds  shall  be rated by  Moody's  and  if  such
corporation  shall  not be a bank or  trust  company,  its
long-term debt or that of its parent shall have a  Moody's
rating  not lower than Baa3 or the equivalent thereof  and
its  short-term debt or that of its parent  shall  have  a
Moody's  rating  not  lower than  P-3  or  the  equivalent
thereof  unless,  in either case, there  shall  have  been
furnished  to  the  Pollution  Control  Corporation,   the
Trustee  and the Company written evidence from Moody's  to
the  effect  that  the appointment of the proposed  Tender
Agent  will  not,  by itself, result  in  a  reduction  or
withdrawal  of  its ratings then in effect on  the  Bonds.
The  Tender Agent may at any time resign and be discharged
of the duties and obligations created by this Indenture by
giving  at  least sixty (60) days' notice to the Pollution
Control   Corporation,  the  Trustee,  the  Company,   the
Remarketing Agent and the Bank.  The Tender Agent  may  be
removed  at  any  time  by  an instrument  signed  by  the
Company,  filed  with  the  Tender  Agent,  and  with  the
Pollution   Control   Corporation,   the   Trustee,    the
Remarketing Agent and the Bank.

    In  the  event  of the resignation or removal  of  the
Tender Agent, the Tender Agent shall deliver any Bonds and
moneys held by it in such capacity to its successor or, if
there be no successor, to the Trustee.

    In the event that the Company shall fail to appoint  a
Tender Agent, or in the event that the Tender Agent  shall
resign  or be removed, or be dissolved, or if the property
or  affairs of the Tender Agent shall be taken  under  the
control  of  any  state or federal court or administrative
body because of bankruptcy or insolvency, or for any other
reason,  and  the  Company shall not  have  appointed  its
successor  as Tender Agent, the entity acting  as  Trustee
shall ipso facto be deemed to be the Tender Agent for  all
purposes  of this Indenture until the appointment  by  the
Company of the Tender Agent or successor Tender Agent,  as
the case may be.

  XIII.13.     Purchase of Bonds; Notices.  (a) On any date
Bonds are to be purchased pursuant to Section 2.02 hereof,
the  Tender Agent shall purchase, as agent and not for its
own  account, but only from the funds listed  below,  such
Bonds  from the Owners thereof at the applicable  purchase
price thereof specified in Section 2.02 hereof.  Funds for
the  payment of such purchase price shall be derived  from
the following sources in the order of priority indicated:

     (i)   moneys furnished by the Trustee to the Tender Agent
  pursuant to Section 8.01 hereof, such moneys to be applied
  only to the purchase of Bonds which are deemed to be paid
  in accordance with Article VIII hereof;

     (ii)  moneys furnished by the Company to the Tender Agent
  pursuant  to  Section 10.02 of the  Loan  Agreement  and
  proceeds  from the investment thereof, which  constitute

  under any Security Arrangement;

     (iv)  moneys representing proceeds of a drawing on the
  Letter  of  Credit  or proceeds of  any  other  Security
  Arrangement; and

     (v)   moneys furnished by the Company to the Tender Agent
  pursuant to Section 10.01 of the Loan Agreement.

     (b)   (i) If moneys sufficient to pay the purchase price
  of Bonds tendered for purchase or required to be tendered
  for  purchase by their terms shall be held by the Tender
  Agent  on the date such Bonds are to be purchased,  such
  Bonds  shall be deemed to have been purchased,  for  all
  purposes of this Indenture, irrespective of whether or not
  such Bonds shall have been delivered to the Tender Agent,
  and  the  former  Owner or Owners shall  have  no  claim
  thereon, under this Indenture or otherwise, for any amount
  other than the purchase price thereof.

  (ii)  The Trustee shall authenticate and deliver to  the
  Tender  Agent  a  new  Bond or  Bonds  in  an  aggregate
  principal amount equal to the principal amount of  Bonds
  deemed  to  have been purchased in accordance with  this
  subsection (b) of Section 13.03 and bearing a number  or
  numbers  not contemporaneously outstanding.  Every  Bond
  authenticated   and  delivered  as   provided   in   the
  preceding  sentence  shall  be  entitled  to   all   the
  benefits  of  this Indenture equally and proportionately
  with  any  and  all  other Bonds duly issued  hereunder.
  The  Tender Agent shall maintain a record of  the  Bonds
  deemed  to  have  been  purchased as  provided  in  this
  subsection  (b)  of  Section 13.03,  together  with  the
  names and addresses of the former Owners thereof.

     (c)   In the event any Bonds shall not be presented for
  purchase  as provided in subsection (b) of this  Section
  13.03,  if moneys sufficient to purchase such Bonds  are
  held  by the Tender Agent for the benefit of the  former
  Owners thereof, the Tender Agent shall segregate and hold
  such  moneys  in trust, without liability  for  interest
  thereon,  for the benefit of the former Owners  of  such
  Bonds,  who  shall, except as provided in the  following
  sentence, thereafter be restricted exclusively  to  such
  fund or funds for the satisfaction of any claim for  the
  purchase price of such Bonds.  Any moneys which the Tender
  Agent shall segregate and hold in trust for the payment of
  the purchase price of any Bond and remaining unclaimed for
  one  year  after  the date of purchase shall,  upon  the
  Company's written request to the Tender Agent, be paid to
  the  Company; provided, however, that before the  Tender
  Agent shall be required to make any such repayment,  the
  Tender  Agent may, at the expense of the Company,  cause
  notice  to be given once by Mail to the former Owner  of
  such Bond or once by Publication, or both, to the effect
  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 the latest such notice,  any
  unclaimed balance of such moneys then remaining will  be
  paid to the Company.  After the payment of such unclaimed
  moneys to the Company, the former Owner of such Bond shall
  thereafter look only to the Company for the payment of the
  purchase price therefor, and all liability of the Tender
  Agent with respect to such moneys shall thereupon cease.

     (d)   (i) On any date Bonds are to be purchased pursuant
  to Section 2.02 and subsection (a) of this Section 13.03,
  the  Tender  Agent  shall give immediate  telephonic  or
  telegraphic  notice,  promptly confirmed  by  a  written
  notice, to the Remarketing Agent specifying the principal
  amount of Bonds delivered to it for purchase.

     (i)    On any date Bonds are to be purchased pursuant to
  Section  2.02 and subsection (a) of this Section  13.03,
  unless the Tender Agent shall have received a notice given
  by  the  Remarketing Agent pursuant to Section  13.06(b)
  hereof  indicating  that all Bonds to  be  sold  by  the
  Remarketing Agent pursuant to Section 13.06(a)  on  such
  date  have  been  remarketed and  that  all  remarketing
  proceeds have been received, the Tender Agent shall give
  telephonic or telegraphic notice no later than 11:15 a.m.,
  New  York  City time, promptly confirmed  by  a  written
  notice, to the Trustee and the Company which notice shall
  specify (A) the principal amount of the Bonds, if any, so
  sold by the Remarketing Agent and the remarketing proceeds
  thereof in its possession and (B) the amount to be drawn
  on  the  Letter of Credit or other Security Arrangement,
  and,  simultaneously therewith, the Tender  Agent  shall
  direct  the  Trustee to make drawings on the  Letter  of
  Credit  or  other Security Arrangement in such specified
  amount in accordance with Section 13.08 hereof.  In giving
  the  foregoing notice the Tender Agent shall utilize the
  information provided to it by the Remarketing Agent in the
  notice  required pursuant to Section 13.06(b); provided,
  however, that in the event that the Tender Agent shall not
  have received such notice from the Remarketing Agent prior
  to  the  Tender  Agent  being required  to  give  notice
  hereunder, the Tender Agent shall assume that such Bonds
  have not been remarketed.

  XIII.14.     Remarketing Agent.  Subject to the conditions
set  forth in Section 13.05 hereof, the Remarketing  Agent
shall  be appointed by the Company.  The Remarketing Agent
shall  designate  its  Principal Office  and  signify  its
acceptance of the duties and obligations imposed  upon  it
hereunder  by a written instrument of acceptance delivered
to  the  Pollution Control Corporation, the  Trustee,  the
Company  and  the  Tender Agent in which  the  Remarketing
Agent will agree, particularly:

     (a)   to hold all Bonds, if any, delivered to it hereunder
  as agent and bailee of, and in escrow for the benefit of,
  the  person or entity which shall have so delivered such
  Bonds until moneys representing the purchase price of such
  Bonds shall have been delivered to or for the account of
  or to the order of such person or entity;

     (b)    to  hold all moneys, if any, delivered  to  it
  hereunder for the purchase of Bonds as agent and  bailee
  of, and in escrow for the benefit of, the person or entity
  which shall have so delivered such moneys until the Bonds
  purchased with such moneys shall have been delivered to or
  for the account of such person or entity; and

     (c)    to  keep  such books and records as  shall  be
  consistent with prudent industry practice and to make such
  books  and  records  available  for  inspection  by  the
  Pollution  Control Corporation, the Trustee, the  Tender
  Agent and the Company at all reasonable times.

    The Pollution Control Corporation shall cooperate with
the  Trustee, the Registrar, the Company, the Tender Agent
and   the   Remarketing  Agent  to  cause  the   necessary
arrangements  to  be  made and to be thereafter  continued
whereby   Bonds,   executed  by  the   Pollution   Control
Corporation  and  authenticated by the Trustee,  shall  be
delivered to the Remarketing Agent to the extent necessary
for  delivery  pursuant to Section 13.07  hereof,  and  to
otherwise  enable the Remarketing Agent to carry  out  its
duties hereunder.

  XIII.15.      Qualifications of Remarketing Agent.   The
Remarketing  Agent shall be (a) a member of  the  National
Association   of  Securities  Dealers,  Inc.,   having   a
capitalization of at least $15,000,000 or (b)  a  bank  or
trust  company  organized under the  laws  of  the  United
States or any state or territory thereof having a combined
capital  stock, surplus and undivided profits of at  least
$15,000,000,  and, in either case, authorized  by  law  to
perform  all the duties imposed upon it by this Indenture;
provided that, if the Bonds shall be rated by Moody's  and
if  the proposed Remarketing Agent shall not be a bank  or
trust  company, its long-term debt or that of  its  parent
shall  have  a Moody's rating not lower than Baa3  or  the
equivalent thereof and its short-term debt or that of  its
parent  shall have a Moody's rating not lower than P-3  or
the equivalent thereof unless, in either case, there shall
have  been furnished to the Pollution Control Corporation,
the  Trustee and the Company written evidence from Moody's
to   the  effect  that  the  engagement  of  the  proposed
Remarketing  Agent  will  not,  by  itself,  result  in  a
reduction  or withdrawal of its ratings then in effect  on
the  Bonds.  The Remarketing Agent may at any time  resign
and be discharged of the duties and obligations created by
this Indenture by giving at least thirty (30) days' notice
to  the  Pollution Control Corporation, the  Trustee,  the
Company,  the Tender Agent and the Bank.  The  Remarketing
Agent  may be removed at any time by an instrument, signed
by  the Company, filed with the Remarketing Agent and with
the  Trustee,  the  Tender Agent,  the  Pollution  Control
Corporation and the Bank.

    In  the  event  of the resignation or removal  of  the
Remarketing Agent, the Remarketing Agent shall  pay  over,
assign and deliver any moneys and Bonds held by it in such
capacity to its successor or, if there be no successor, to
the Tender Agent.

    In  the event that the Company shall fail to engage  a
Remarketing  Agent  hereunder, or in the  event  that  the
Remarketing  Agent  shall resign  or  be  removed,  or  be
dissolved,   or  if  the  property  or  affairs   of   the
Remarketing Agent shall be taken under the control of  any
state  or federal court or administrative body because  of
bankruptcy or insolvency, or for any other reason, and the
Company   shall  not  have  appointed  its  successor   as
Remarketing  Agent, the Tender Agent, notwithstanding  the
provisions  of the first paragraph of this Section  13.05,
shall ipso facto be deemed to be the Remarketing Agent for
all  purposes  of this Indenture until the appointment  by
the   Company  of  the  Remarketing  Agent  or   successor
Remarketing Agent, as the case may be; provided,  however,
that  the  Tender  Agent, in its capacity  as  Remarketing
Agent,  shall  not be required to sell Bonds  pursuant  to
Section  13.06  hereof  if  the  Tender  Agent  should  be
prohibited by law from conducting such activities.

hereof, the Remarketing Agent shall offer for sale and use
its  best efforts to sell such Bonds, any such sale to  be
made  on  the date such Bonds are to be purchased pursuant
to  such tender, at a price at least equal to the purchase
price  thereof plus interest accrued thereon, if  any,  to
the  date  of sale; provided, however, that to the  extent
that any moneys described in clause (i) or (ii) of Section
13.03(a) shall be on deposit with Tender Agent, any  Bonds
delivered to the Tender Agent which may be purchased  with
such moneys shall be so purchased and shall not be offered
for  sale  or sold by the Remarketing Agent; and provided,
further, that in no event shall Bonds be sold pursuant  to
this  Section 13.06 to the Company, any Affiliate  of  the
Company,   the  Pollution  Control  Corporation   or   any
"insider"  of  either thereof within the  meaning  of  the
United  States Bankruptcy Code, 11 U.S.C. Section  101  et
seq.,  if  there shall be in effect a Security Arrangement
on which the Company shall not be the obligor.

Remarketing  Agent  pursuant to  subsection  (a)  of  this
Section  13.06, the Remarketing Agent shall give immediate

       purchase of Bonds delivered pursuant to Section 2.02
       hereof and not remarketed by the delivery to the Bank of
       such Bonds;

          (ii)   held by the Tender Agent for the account of the
       Company subject to a security interest in favor of the
       Bank, if the Letter of Credit provides for reinstatement
       in respect of the drawings described in clause (i) of this
       Section 13.07(c) by reimbursement to the Bank of the
       amount of such drawings together with interest thereon; or

             (iii)  if a Security Arrangement other than a

       thereon.

  (c)   Bonds purchased with moneys described in clause (v)

Bank or such other Owner, as the case may be.  The excess,
if  any,  of the price at which a Bond shall be remarketed

XIV                   MISCELLANEOUS

  XIV.11.        Successors  of  the   Pollution   Control
Corporation.   In  the  event of the  dissolution  of  the
Pollution   Control   Corporation,  all   the   covenants,
stipulations,  promises and agreements in  this  Indenture
contained, by or on behalf of, or for the benefit of,  the
Pollution Control Corporation, shall bind or inure to  the
benefit   of  the  successors  of  the  Pollution  Control
Corporation  from  time to time and any  entity,  officer,
board, commission, agency or instrumentality to whom or to
which   any  power  or  duty  of  the  Pollution   Control
Corporation shall be transferred.

  XIV.12.       Parties  in Interest.   Except  as  herein
otherwise specifically provided, nothing in this Indenture
expressed or implied is intended or shall be construed  to
confer upon any person, firm or corporation other than the
Pollution  Control Corporation, the Company,  the  Trustee
and  the  Bank  and their successors and assigns  and  the
Owners of the Bonds any right, remedy or claim under or by
reason of this Indenture, this Indenture being intended to
be  for  the  sole and exclusive benefit of the  Pollution
Control Corporation, the Company, the Trustee and the Bank
and  their  successors and assigns and the Owners  of  the
Bonds.

  XIV.13.      Severability.  In case any one or more of the
provisions  of this Indenture or of the Loan Agreement  or
of  the Bonds shall, for any reason, be held to be illegal
or invalid, such illegality or invalidity shall not affect
any  other  provisions of this Indenture or  of  the  Loan
Agreement  or  of such Bonds, and this Indenture  and  the
Loan  Agreement  and  such Bonds shall  be  construed  and
enforced as if such illegal or invalid provisions had  not
been contained herein or therein.

  XIV.14.       No Personal Liability of Pollution Control
Corporation Officials.  No covenant or agreement contained
in  the Bonds or in this Indenture shall be deemed  to  be
the  covenant  or  agreement of  any  director,  official,
officer,  agent,  or  employee of  the  Pollution  Control
Corporation  in his individual capacity, and  neither  the
members of the Board of Directors of the Pollution Control
Corporation nor any official executing the Bonds shall  be
liable  personally  on  the Bonds or  be  subject  to  any
personal  liability or accountability  by  reason  of  the
issuance thereof.

  XIV.15.        Bonds  Owned  by  the  Pollution  Control
Corporation or the Company.  In determining whether Owners
of  the requisite aggregate principal amount of the  Bonds
have  concurred in any direction, consent or waiver  under
this  Indenture,  Bonds which are owned by  the  Pollution
Control  Corporation  or  the Company  or  by  any  person
directly  or  indirectly controlling or controlled  by  or
under  direct or indirect common control with the  Company
(unless the Pollution Control Corporation, the Company  or
such  person  owns  all Bonds which are then  Outstanding,
determined without regard to this Section 14.05) shall  be
disregarded  and  deemed  not to be  Outstanding  for  the
purpose  of any such determination, except that,  for  the
purpose  of  determining  whether  the  Trustee  shall  be
protected  in  relying on any such direction,  consent  or
waiver,  only Bonds which the Trustee knows are  so  owned
shall be so disregarded.  Upon the request of the Trustee,
the  Company  and the Pollution Control Corporation  shall
furnish  to  the  Trustee  a certificate  identifying  all
Bonds,  if  any, actually known to either of  them  to  be
owned  or  held  by  or  for the account  of  any  of  the
above-described persons, and the Trustee shall be entitled
to  rely on such certificate as conclusive evidence of the
facts  set  forth  therein and that all  other  Bonds  are
Outstanding for the purposes of such determination.  Bonds
so  owned  which have been pledged in good  faith  may  be
regarded as Outstanding if the pledgee establishes to  the
satisfaction of the Trustee the pledgee's right so to  act
with respect to such Bonds and that the pledgee is not the
Pollution Control Corporation or the Company or any person
directly  or  indirectly controlling or controlled  by  or
under  direct or indirect common control with the Company;
provided,  however, that Bonds delivered to the  Bank,  or
held by the Tender Agent, pursuant to Section 14.07 hereof
shall  be  regarded as Outstanding for  purposes  of  this
Section 14.05.  In case of a dispute as to such right, any
decision  by the Trustee taken upon the advice of  counsel
shall be full protection to the Trustee.

  XIV.16.      Counterparts.  This Indenture may be executed
in  any  number  of counterparts, each of which,  when  so
executed  and  delivered, shall be an original;  but  such

same Indenture.

  XIV.17.       Governing Law.  The laws of the  State  of
Arizona  shall govern the construction and enforcement  of
this  Indenture and of all Bonds, except that the laws  of

enforcement  of  the  rights and  duties  of  the  Trustee
hereunder and the construction of Section 14.09 hereof and
the computation of any period of grace provided herein.

  XIV.18.       Notices.  Except as otherwise provided  in

securing,  drafting or creating the contract on behalf  of
the political subdivisions or any of their departments  or

understood  and  agreed that failure to provide  any  such

   Coconino County, Arizona Pollution Control Corporation,
a  political  subdivision of the  State  of  Arizona  (the
"Pollution  Control  Corporation"),  for  value  received,
hereby  promises to pay (but only out of the Receipts  and
Revenues  of  the Pollution Control Corporation  from  the
Loan  Agreement, as hereinafter defined, and other  moneys
pledged therefor) to the Registered Owner identified above
or  registered  assigns, on the Maturity  Date  set  forth
above,  upon  the presentation and surrender  hereof,  the
Principal Amount set forth above and to pay (but only  out
of  the  Receipts  and Revenues of the  Pollution  Control
Corporation  from  the  Loan Agreement  and  other  moneys
pledged therefor), interest on said Principal Amount until
said Principal Amount has become due and payable, from the
Interest  Payment Date (as hereinafter defined)  to  which
interest  on this Bond shall have been paid in full  which
is, or immediately precedes, the date of authentication of
this  Bond or, if no interest shall have been paid on  the
Bonds,   from  the  date  of  original  issuance  thereof.
Interest  shall be paid on each Interest Payment Date  (as
hereinafter defined) at the rates determined as set  forth
in  the Indenture and described herein.  Interest on  this
Bond  will  be paid at the lesser of (a) a Daily  Rate,  a
Weekly Rate, a Monthly Rate, a Flexible Rate, a Term  Rate
or  the  Fixed Rate (each as defined in the Indenture)  as
selected in accordance with the Indenture and (b) 12%  per
annum.   Interest will be initially payable  at  a  Weekly
Rate.   While there exists an Event of Default  under  the
Indenture, the interest rate on the Bonds will be the rate
on  the  Bonds  on  the day before the  Event  of  Default
occurred,  except that if interest on the Bonds  was  then
payable  at Flexible Rates, the default rate will  be  the
highest Flexible Rate then in effect for any Bond.

  When interest is payable at a Variable Rate other than a
Term Rate or a Flexible Rate, interest will be computed on
the basis of the actual number of days elapsed over a year
of  365 days (366 in leap years).  When payable at a  Term
Rate  or the Fixed Rate, interest will be computed on  the
basis  of  a  360-day year of twelve 30-day  months.   For
purposes of any such calculation of interest payable  with
respect  to the final interest payment during a Term  Rate
Period  immediately followed by a Flexible, Daily,  Weekly
or Monthly Rate Period, the amount of interest which shall
be  payable  with  respect to such final  interest  period
shall  be  determined as if the Interest Payment Date  for
such  period  were  the  first  day  of  the  sixth  month
following    the   preceding   Interest   Payment    Date,
notwithstanding any extension of such month to  the  first
Business  Day  (as hereinafter defined) of such  month  by
reason  of the conversion to such Flexible, Daily,  Weekly
or Monthly Rate Period.

   As  used  in  this Bond, "Interest Payment Date"  means
(a)  when this Bond bears interest at the Daily or Monthly
Rate,  the  first Business Day of each calendar  month  to
which  interest at such rate has accrued,  (b)  when  this
Bond  bears interest at a Weekly Rate, the first Wednesday
of  each calendar month to which interest at such rate has
accrued, (c) when this Bond bears interest at a Term  Rate
or  the  Fixed  Rate, the first day of the sixth  calendar
month following the month in which the Term or Fixed  Rate
Conversion  Date (as defined in the Indenture) occurs  and
the  first day of each sixth calendar month thereafter  to
which  interest at such rate has accrued, except that  the
last  Interest Payment Date for any Term Rate Period which
is followed by a conversion to any type of Rate Period (as
defined below) (except a Term or Fixed Rate Period)  shall
be the first Business Day of the sixth month following the
preceding Interest Payment Date, (d) when this Bond  bears
interest at a Flexible Rate, the day after the last day of
each Flexible Rate Period applicable thereto, and (e)  May
1, 2031.

  The regular record date ("Record Date") for any Interest
Payment  Date  shall  be  the close  of  business  on  the
(a) Business Day immediately preceding an Interest Payment
Date,  in  the case of Bonds bearing interest at Flexible,
Daily,   Weekly  and  Monthly  Rates,  and  (b)  fifteenth
(15th) day (whether or not a Business Day) of the calendar
month immediately preceding the Interest Payment Date,  in
the  case of Bonds bearing interest at a Term Rate or  the
Fixed Rate.

   As  used  in this bond, "Rate Period" means the  period
during which a particular rate of interest determined  for
the  Bonds as hereinafter provided is to remain in  effect
until  a subsequently determined rate of interest pursuant
to Article II of the Indenture becomes effective.

   Prior  to  any conversion of the interest rate  on  the
Bonds  to  the Fixed Rate, the Bonds may bear interest  at
Flexible  Rates or a Variable Rate effective for "Flexible
Rate  Periods" in the case of Flexible Rates and "Variable
Rate  Periods" in the case of Variable Rates  selected  by
the Company from time to time.  The rate of interest to be
borne by the Bonds during any particular Rate Period  will
be  determined  by the Remarketing Agent.  The  Bonds  may
bear interest as follows:

Variable Rates

   The Bonds may bear interest at a Variable Rate computed
on  a  Daily, Weekly, Monthly or Term basis in  accordance
with the applicable provisions of the Indenture.

  Daily Rate.

   While  the  Bonds bear interest at a  Daily  Rate,  the
interest  rate established for the Bonds will be effective
from day to day until changed by the Remarketing Agent.

  Weekly Rate.

  While the Bonds bear interest at a Weekly Rate, the rate
of interest on the Bonds will be determined on the Tuesday
or  next  Business Day immediately preceding the Wednesday
which  is the commencement date of the Weekly Rate  Period
by  the  Remarketing Agent to be effective for a seven-day
period  commencing  on such Wednesday and  ending  on  the
following Tuesday.

  Monthly Rate.

   While  the Bonds bear interest at a Monthly  Rate,  the
rate  of  interest  will  be  determined  monthly  by  the
Remarketing   Agent  on  the  Business   Day   immediately
preceding the commencement date of the Monthly Rate Period
to  which  it  relates  to be in effect  for  the  related
Monthly Rate Period.

  Term Rate.

   While  the  Bonds  bear interest at a  Term  Rate,  the
interest rate will be determined by the Remarketing  Agent
on the Business Day immediately preceding the commencement
date  of  the  Term Rate Period to which it relates,  such
interest  rate  to remain in effect for the  related  Term
Rate Period.

Flexible Rates

   While  the  Bonds bear interest at Flexible Rates,  the
interest  rate for each particular Bond will be determined
by the Remarketing Agent and will remain in effect for the
duration  (not  exceeding 270 days) of the  Flexible  Rate
Period  selected  for that Bond by the Remarketing  Agent.
While the Bonds bear interest at Flexible Rates, Bonds may
have  successive Flexible Rate Periods of any duration  up
to  270 days each and any Bond may bear interest at a rate
and for a period different from any other Bond.

Fixed Rate

  If the Bonds are to bear interest at the Fixed Rate, the
interest rate will be determined by the Remarketing  Agent
and  will remain in effect until the final maturity of the
Bonds.

   The duration and beginning and ending dates of any Rate
Period  may vary in the event of conversions between  Rate
Periods.  The type of Rate Period selected by the  Company
will  remain  in  effect until changed by the  Company  in
accordance with the Indenture.

   Bonds  which  bear interest at Flexible Rates  will  be
issued  in  the  determination of  $100,000  and  integral
multiples  of $5,000 in excess thereof.  Bonds which  bear
interest at a Daily, Weekly or Monthly Rate will be issued
in   denominations  of  $100,000  and  integral  multiples
thereof.   Bonds which bear interest at a  Term  or  Fixed
Rate  will  be  issued in the denomination of  $5,000  and
integral multiples thereof.

OPTIONAL TENDERS

Bond  for  purchase  at the principal amount  hereof  plus

purchase  (i) while this Bond bears interest at a Flexible
Rate,  on  the day following the last day of each Flexible
Rate  Period  applicable to this Bond at a purchase  price
equal  to  100% of the principal amount hereof,  provided,
however,  that  this  Bond shall not be  subject  to  such
mandatory  tender for purchase if, prior to 3:00  p.m.  on
the  Business  Day next preceding the day  such  mandatory
tender  would otherwise occur, the Owner of this  Bond  by

Weekly  Rate  Periods) or from any Term Rate Period  to  a
Term  Rate  Period of a different duration, at a  purchase
price  equal  to  100%  of the principal  amount  thereof,
(iii)  at  the  price  that would be the  then  applicable
redemption  price  set forth in the redemption  provisions

which  the  expiration or termination of the term  of  any
Security Arrangement (as hereinafter defined) shall occur;
provided,  however, that there shall be no such  mandatory
tender  if the Company shall have delivered to the  Tender
Agent  letters or certificates to the effect specified  in
Section  6.07(c) of the Loan Agreement, and  (iv)  on  the
first Business Day on which the Trustee may make a drawing
or drawings on a Security Arrangement on which the Company

drawing  or  drawings shall be immediately available,  but
not  prior  to such date, on or after the receipt  by  the
Trustee of notice that either (a) following a drawing on a
Security Arrangement on which the Company shall not be the
obligor  to  pay  accrued  interest,  or  the  portion  of
purchase  price equal to accrued interest, on  the  Bonds,
that  the  amount available to be drawn on  such  Security
Arrangement will not be reinstated to the amount specified
in  the Indenture, or (b) an "Event of Default" under  the
Reimbursement  Agreement has occurred and  is  continuing,
unless  in  either such case, the notice received  by  the
Trustee also directs it to provide notice to the Pollution
Control Corporation of its obligation to redeem the  Bonds
pursuant to the Indenture.

   If an Owner of a Bond is required to tender its Bond as
set  forth  in the preceding paragraph such Bond  will  be
deemed to be purchased at the price set forth above on the
date   that   the  Bond  is  required  to   be   tendered,
notwithstanding  the  failure  of  the  Owner  thereof  to
deliver  the Bond to the Tender Agent.  If a  Bond  is  so
deemed  to be purchased, the Owner thereof at the time  of
such  purchase  shall  not  be  entitled  to  receive  any
interest accruing on such Bond on and after the date it is
deemed  to be purchased, and shall not be entitled to  any
benefits  under  the Indenture except  for  the  right  to
receive the purchase price for such Bond.

WRITTEN NOTICE OF CHANGE IN TYPE OF RATE PERIOD

   While this Bond bears interest at a Flexible Rate or at
a Variable Rate, the Tender Agent shall give notice to the
Owners  of  all Bonds of the conversion from one  type  of
Rate  Period to another type of Rate Period (or to a  Term
Rate  Period  from  a  Term Rate  Period  of  a  different
duration) at the times described in the Indenture.  If the
Company does not elect in a timely fashion to convert to a
new  type  of Rate Period for the Bonds (or to a different
Term  Rate Period for the Bonds) or any condition to  such
conversion under the Indenture is not satisfied, the  type
of  Rate Period then in effect will continue until changed
by  timely notice and, in the case of a Term Rate  Period,
the duration of the Term Rate Period shall be one year.

CONVERSION TO THE FIXED RATE

    The   Indenture  provides  that,  subject  to  certain
conditions,  the  Company has the  right  to  convert  the
interest  rate on this Bond to the Fixed Rate to maturity.

registered Owner hereof.  Interest on this Bond is payable
by  check  drawn upon the Paying Agent and mailed  to  the
registered address of the registered owner of this bond as

respect  of a Term Rate Period and the Fixed Rate  Period,
owners  of  not  less than $1,000,000 aggregate  principal
amount  of  Bonds may request that interest on  the  Bonds
and,  after presentation and surrender of such Bonds,  the

by  the  owner thereof.  Payment of the principal  of  and
premium,  if any, and interest on, and purchase price  of,
this  Bond shall be in any coin or currency of the  United

                                       thereafter at 100%

                    commencement of
                    next Rate Period,
                    if any

   Anything  herein or in the Indenture  to  the  contrary
notwithstanding,  in  the event  that  the  Company  shall
consolidate with, merge with or into, or sell or otherwise
transfer  all  or  substantially all  of  its  assets  to,
another corporation in accordance with Section 6.01 of the
Loan  Agreement, the Bonds shall be subject to  redemption
by  the Pollution Control Corporation, at the direction of
the Company, in whole, at any time prior to the first date
on  which  the  Bonds  are  redeemable  as  herein  before
provided,   at  the  redemption  price  which   would   be
applicable  on  such  date plus accrued  interest  to  the
redemption date.

   (d)  The Bonds shall be subject to mandatory redemption
by  the  Pollution Control Corporation, at  the  principal
amount  thereof  plus accrued interest to  the  redemption
date,  on  the 180th day (or such earlier date as  may  be
designated by the Company) after a final determination  by
a  court  of  competent jurisdiction or an  administrative
agency,  to  the effect that, as a result of a failure  by
the  Company to perform or observe any covenant, agreement
or  representation  contained in the Loan  Agreement,  the
interest  payable  on  the Bonds is included  for  Federal
income  tax  purposes in the gross income  of  the  owners
thereof,  other  than  any  owner  of  a  Bond  who  is  a
"substantial user" of the Facilities or a "related person"
within  the meaning of Section 103(b)(13) of the  Internal
Revenue  Code  of  1954,  as amended,  as  applicable.  No
determination by any court or administrative agency  shall
be considered final for the purposes of this paragraph (d)
unless the Company shall have been given timely notice  of
the proceeding which resulted in such determination and an
opportunity  to  participate in  such  proceeding,  either
directly  or  through an owner of a Bond,  and  until  the
conclusion of any appellate review sought by any party  to
such  proceeding or the expiration of the time for seeking
such  review. The Bonds shall be redeemed either in  whole
or  in  part  in such principal amount that  the  interest
payable  on  the  Bonds remaining outstanding  after  such
redemption  would not be included in the gross  income  of
any owner thereof, other than an owner of a Bond who is  a
"substantial user" of the Facilities or a "related person"
within the meaning of Section 103(b)(13) of the 1954 Code.

   (e)  In the event that the aggregate of the amounts, if
any,  of  the  proceeds of the Bonds remaining  unexpended
upon  the  completion  of  the  Facilities  or  upon   the
termination  of the acquisition and construction  thereof,
together with any income or other gain from the investment
thereof, shall at any time, or from time to time, be equal
to   or  greater  than  $100,000,  the  Pollution  Control
Corporation  shall  redeem the  Bonds,  at  the  principal
amount  thereof  plus accrued interest to  the  redemption
date, in the largest aggregate principal amount which does
not  exceed  the  amount  of such proceeds  together  with
income   or  other  gain  on  an  Interest  Payment   Date
determined  as  set forth in, and otherwise in  accordance
with  the provisions of, the Indenture; provided, however,
that  the Company may direct that such proceeds and income
be  applied to the purchase of the Bonds or in  any  other
manner which will not impair the validity of the Bonds  or
the  exemption from Federal income taxes of  the  interest
thereon.

   (f)  The Bonds shall be subject to mandatory redemption
by  the  Pollution Control Corporation, at  the  principal
amount  thereof  plus accrued interest to  the  redemption
date,  upon  the  occurrence of either  of  the  following
events:

     (i)  receipt by the Trustee, following a drawing on a
  Security Arrangement on which the Company shall  not  be
  the  obligor to pay accrued interest, or the portion  of
  purchase price equal to accrued interest, on the  Bonds,
  of  notice from the Bank that the amount available to be
  drawn   on  such  Security  Arrangement  will   not   be
  reinstated  (in  respect  of  interest  or  portion   of
  purchase price equal to accrued interest) in the  amount
  of  such  drawing and directing the Trustee  to  provide
  notice  to  the  Pollution Control  Corporation  of  its
  resulting obligation to redeem the Bonds; or

     (ii)  receipt by the Trustee of notice from the  Bank
  stating   that   an   Event   of   Default   under   the
  Reimbursement Agreement (or other agreement between  the
  Company  and the Bank pursuant to which the Bank  issued
  and  delivered  to  the Trustee a Security  Arrangement)
  has   occurred  and  is  continuing  and  directing  the
  Trustee  to  provide  notice to  the  Pollution  Control
  Corporation  of its resulting obligation to  redeem  the
  Bonds.

  Upon the occurrence of either of the events described in
the immediately preceding paragraph, the Pollution Control
Corporation shall be obligated to redeem the Bonds on  the
first  Business Day after the occurrence of such event  on
which  the  Trustee may make a drawing or  drawings  on  a
Security Arrangement on which the Company shall not be the
obligor  and  on  which the proceeds of  such  drawing  or
drawings  shall  be available, but shall  not  redeem  the
Bonds prior to such date.

   The  provisions  of clause (f) of the second  preceding
paragraph  are subject to the condition that if either  of
the  events described in clause (i) or (ii) of the  second
preceding paragraph shall have occurred and if the Trustee
shall  thereafter have received notice from the  Bank  (a)
that  the  notice  which requires a  mandatory  redemption
pursuant  to  the  second  preceding  paragraph  has  been
withdrawn and (b) that the amounts available to  be  drawn
on  the  Security Arrangement to pay (i) the principal  of
the  Bonds  or  the  portion of purchase  price  equal  to
principal  and (ii) interest on the Bonds and the  portion
of  purchase  price  equal to accrued interest  have  been
reinstated then, in every such case, the event giving rise
to  such mandatory redemption shall be deemed to be waived
and all proceedings for such redemption shall be rescinded
and annulled.

   If  less  than all of the Bonds at the time outstanding
are  to be called for redemption, the particular Bonds  or
portions of Bonds to be redeemed shall be selected by  the
Trustee,  in such manner as the Trustee in its  discretion
may  deem  proper, in the principal amounts designated  to
the Trustee by the Company or otherwise as required by the
Indenture;  provided, however, that, if the Company  shall
have  offered  to purchase all Bonds then outstanding  and
less than all such Bonds have been tendered to the Company
for  such purchase, the Trustee, at the direction  of  the
Company, shall select for redemption all such Bonds  which
shall not have been so tendered.

  In the event any of the Bonds are called for redemption,
the  Trustee  shall  give  notice,  in  the  name  of  the
Pollution Control Corporation, of the redemption  of  such
Bonds.   Such notice shall be given by mailing a  copy  of
the  redemption notice by first-class mail at least thirty
(30)  days  prior  (except in the  case  of  a  redemption
pursuant  to clause (f) of the fourth preceding paragraph)
to  the  date  fixed for redemption to the owners  of  the
Bonds  to  be  redeemed  at the  addresses  shown  on  the
registration  books; provided, however, that failure  duly
to  give  such  notice by mailing, or any defect  therein,
shall  not affect the validity of any proceedings for  the
redemption of the Bonds as to which there shall be no such
failure or defect.

   With  respect to any notice of redemption of  Bonds  in
accordance  with the redemption provisions  lettered  (a),
(b)  or (c) above, unless, upon the giving of such notice,
such  Bonds  shall be deemed to have been paid within  the
meaning  of  the Indenture, such notice shall  state  that
such redemption, shall be conditional upon the receipt, by
the  Trustee on or prior to the opening of business on the
date fixed for such redemption of moneys sufficient to pay
the principal of and premium, if any, and interest on such
Bonds  to  be redeemed, and that if such moneys shall  not
have been so received said notice shall be of no force and
effect and the Pollution Control Corporation shall not  be
required  to  redeem such Bonds. In the  event  that  such
notice  of redemption contains such a condition  and  such
moneys  are not so received, the redemption shall  not  be
made  and  the  Trustee  shall within  a  reasonable  time
thereafter give notice, in the manner in which the  notice
of  redemption  was given, that such moneys  were  not  so
received.

   If a notice of redemption shall be unconditional, or if
the conditions of a conditional notice of redemption shall
have  been satisfied, then upon presentation and surrender
of  Bonds so called for redemption at the place or  places
of payment, such Bonds shall be redeemed.

   Any  Bonds and portions of Bonds which have  been  duly
selected  for redemption or deemed selected for redemption
and  which  are deemed to be paid in accordance  with  the
Indenture  shall cease to bear interest on  the  specified
redemption date and shall thereafter cease to be  entitled
to any lien, benefit or security under the Indenture.

   The  owner of this Bond shall have no right to  enforce
the provisions of the Indenture, or to institute action to
enforce the covenants therein, or to take any action  with
respect  to  any  default  under  the  Indenture,  or   to
institute,  appear  in  or  defend  any  suit   or   other
proceeding with respect thereto, except as provided in the
Indenture.

    With  certain  exceptions  as  provided  therein,  the
Indenture  and  the  Loan Agreement  may  be  modified  or
amended  only with the consent of the owners of a majority
in  aggregate  principal amount of all  Bonds  outstanding
under  the  Indenture  which would be  adversely  affected
thereby.

   Reference is hereby made to the Indenture and the  Loan
Agreement,  copies of which are on file with the  Trustee,
for  the  provisions, among others, with  respect  to  the
nature and extent of the rights, duties and obligations of
the   Pollution  Control  Corporation,  the  Company,  the
Trustee, the Remarketing Agent, the Tender Agent, the Bank
and  the  owners of the Bonds. The owner of this Bond,  by
the  acceptance  hereof,  is deemed  to  have  agreed  and
consented to the terms and provisions of the Indenture and
the Loan Agreement.

   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  within the meaning and with the effect expressed  in
the   Indenture,  and  the  entire  indebtedness  of   the
Pollution Control Corporation in respect thereof shall  be
satisfied  and  discharged, if there has been  irrevocably
deposited  with the Trustee, in trust, money in an  amount
which will be sufficient and/or Government Obligations (as
defined  in the Indenture), the principal of and  interest
on  which,  when  due, without regard to any  reinvestment
thereof,  will provide moneys which, together with  moneys
deposited with or held by the Trustee, will be sufficient,
to  pay when due the principal of and premium, if any, and
interest  on  this Bond or such portion of  the  principal
amount hereof when due.

   The  Pollution  Control Corporation, the  Trustee,  the
Registrar,  the Tender Agent, the Remarketing  Agent,  the
Paying  Agent, any authenticating agent and any  co-paying
agent  may  deem and treat the person in whose  name  this
Bond  is  registered as the absolute owner hereof for  all
purposes, whether or not this Bond is overdue, and neither
the Pollution Control Corporation, the Trustee, the Tender
Agent,  the  Remarketing Agent, the Paying Agent  nor  any
co-paying  agent shall be affected by any  notice  to  the
contrary.

   It  is hereby certified, recited and declared that  all
acts,  conditions and things required by the  Constitution
and  laws  of  the  State of Arizona  to  exist,  to  have
happened and to have been performed, precedent to  and  in
the  execution  and  delivery of  the  Indenture  and  the
issuance  of this Bond, do exist, have happened  and  have
been performed in regular and due form as required by law.

   No  covenant or agreement contained in this Bond or the
Indenture shall be deemed to be a covenant or agreement of
any  official, officer, agent or employee of the Pollution
Control  Corporation  in  his  individual  capacity,   and
neither  the  members  of the Board of  Directors  of  the
Pollution  Control Corporation, nor any official executing
this  Bond, shall be liable personally on this Bond or  be
subject  to  any  personal liability or accountability  by
reason of the issuance or sale of this Bond.

   This Bond shall not be entitled to any right or benefit
under the Indenture, or be valid or become obligatory  for
any purpose, until this Bond shall have been authenticated
by  the  execution  by the Trustee, or  its  successor  as
Trustee,  or  an  authenticating  agent  thereof,  of  the
certificate of authentication inscribed hereon.

    IN WITNESS WHEREOF, Coconino County, Arizona Pollution

          any Advance shall be effective if it would cause the aggregate
          duration of all Interest Periods applicable to such Advance to
          extend beyond the Stated Termination Date.  The first day of the

          Advance is made and the first day of each subsequent Interest
          Period for such Advance shall be the date on which the applicable

          which the unpaid principal amount of any Advance shall be reduced, by
          payment or prepayment or otherwise, to less than $1,000,000, the
          rate of interest on the unpaid principal amount of such Advance
          shall be equal to the Base Rate, and the right of the Company to
          select a different rate for such Advance shall terminate;
          provided, however, that if and so long as the Company shall
          select for such Advance the same rate for the same Interest
          Period as another Advance or other Advances and the aggregate
          unpaid principal amount of all such Advances shall equal or
          exceed $1,000,000, the Company shall have the right to select
          such rate for such Interest Period for such Advance.

                  (vi)      Default Rate.  Notwithstanding any provision to 
          the contrary herein (including, without limitation, any interest
          elections under this subsection (b)) the Company shall pay
          interest on all past-due Advances and (to the fullest extent
          permitted by law) interest, costs, fees and expenses hereunder,
          from the date when such amounts became due until paid in full,
          payable on demand, at the Default Rate in effect from time to
          time.

          (b)       If, on or before any date on which a Eurodollar Advance
would otherwise be made hereunder, pursuant to paragraph (iii) of
Section 2.6(b), either (i) the Agent determines or is notified by
any of the Banks that funding in the manner contemplated in
paragraph (iii), as the case may be, of Section 2.6(b) is not
reasonably available or (ii) the Agent determines or is notified
by any of the Banks that the rate of interest so elected for the
relevant Interest Period would not adequately reflect the cost to
the Banks of making, funding or maintaining such Advance for such
Interest Period, the Agent shall forthwith give telephonic notice
(confirmed promptly in writing) to the Company and telephonic
notice to each Bank of such determination or notification,
whereupon the Company shall not be entitled hereunder to elect to
pay interest at the rate provided in paragraph (iii) of Section
2.6(b) for such Interest Period; and such Advance shall bear
interest as provided in Section 2.6(b)(i) and shall have an
Interest Period as provided in Section 2.6(a).

          II.7   Reimbursement Obligations Deemed to be Loans; Funding by
Banks to CIBC. (a)  In the event that CIBC makes any payment or
disbursement under the Letter of Credit or any draft accepted
thereunder (including any Advance) and the Company shall not have
reimbursed CIBC in full for such payment or disbursement on the
same Business Day in accordance herewith, each Bank shall be
obligated to pay CIBC in full or partial payment of the purchase
price of its participation in the Letter of Credit, its pro rata
share, according to the amount of its Percentage, of such payment
or disbursement (but such obligation of the Banks shall not
diminish the obligation of the Company hereunder), and the Agent
shall promptly notify each other Bank thereof.  Each other Bank
irrevocably and unconditionally agrees to pay to the Agent in
immediately available funds for CIBC's account the amount of such
other Bank's Percentage of such payment or disbursement, without
setoff, counterclaim, recoupment or any reduction for any reason.
If and to the extent any Bank shall not have made such amount
available to the Agent by 3:00 P.M., New York time, on the
Business Day on which such Bank receives notice from the Agent of
payment or disbursement (it being understood that such notice
received after 1:30 P.M., New York time, on any Business Day
shall be deemed to have been received on the next following
Business Day), such Bank agrees to pay interest on such amount to
the Agent for CIBC's account forthwith on demand for each day
from and including the date such amount was to have been
delivered to the Agent to but excluding the date such amount is
paid, at a rate per annum equal to the Federal Funds Rate.  Any
Bank's failure to make available to the Agent its Percentage of
any such payment or disbursement shall not relieve any other Bank
of its obligation hereunder to make available to the Agent such
other Bank's Percentage of such payment, but no Bank shall be
responsible for the failure of any other Bank to make available
to the Agent such other Bank's Percentage of any such payment or
disbursement.

     (a)       Without limitation to the foregoing provisions of this
Section 2.7, if a Bank shall, at any time, fail to make any
payment to the Agent required under Section 2.7(a) (a "Funding
Default"), CIBC may, but shall not be required to, cause the
Agent to retain payments that would otherwise be made to such
Bank hereunder and apply such payments to such Bank's defaulted
obligations hereunder, at such time, and in such order, as CIBC
may elect in its sole discretion.  Upon a Funding Default by a
Bank, CIBC shall have the right, but not the obligation, to
terminate and repurchase such Bank's participation in all or, in
its discretion, any portion of the Letter of Credit, for a
purchase price equal to such Bank's proportionate share of the
then unpaid principal balance of the outstanding Advances, if
any, being repurchased, together with interest, fees and other
amounts accrued and owing thereon (reduced by an amount equal to
such Bank's Percentage of any such Advance or portion thereof
with respect to which such Bank has not, as of the time of such
repurchase, reimbursed CIBC in full in accordance with Section
2.7(a) and by the amount of any costs or expenses incurred by
CIBC or the Agent in connection with such Bank's Funding Default
and such repurchase), and terminate such Bank's obligations
hereunder with respect to the repurchased Advances and any
Drawings then made under the Letter of Credit with respect to
which CIBC has not made payment as of the time of purchase.  Upon
the occurrence and continuance of a Funding Default by a Bank,
the Agent and CIBC shall not be required to obtain the consent of
such Bank to any action as provided in this Section 2.7.

          II.8   Prepayments; Reinstatement of Letter of Credit Amounts.
(a)  The Company may, upon at least two Business Days' notice to
the Agent, prepay the outstanding amount of any Base Advance in
whole or in part (which prepayment shall be at least $1,000,000)
with accrued interest to the date of such prepayment on the
amount prepaid by making payment to the Agent for the pro rata
share of the Banks.  Except for prepayments made pursuant to
subsection (b) of this Section 2.8, the Company shall not be
entitled to prepay any Eurodollar Advance; provided, however,
that the Company may repay any Eurodollar Advance on the last day
of the Interest Period applicable thereto upon at least two
Business Days' notice to the Agent.  Any prepayment of a
Eurodollar Advance made pursuant to subsection (b) below, Section
6.2 or otherwise shall be accompanied by an additional payment,
in accordance with Section 2.9(b), of an amount sufficient to
compensate the Banks affected, as determined by each such Bank
and notified to the Agent, for any loss (including loss of
anticipated profits), cost or expense incurred by such Banks by
reason of such prepayment.

          (a)       Prior to or simultaneously with the receipt of proceeds
related to the resale of Bonds purchased pursuant to one or more
draws under the Letter of Credit by one or more Tender Drawings,
the Company shall directly or through the Remarketing Agent or
the Tender Agent on behalf of the Company, prepay the then
outstanding Advances (in the order in which they were made) by
paying to the Agent for the pro rata share of the Banks an amount
equal to the sum of (i) the aggregate principal amount of the
Bonds resold plus (ii) that aggregate amount of interest on such
Bonds which was paid by such Tender Drawing or Drawings.

          II.9   Increased Costs.  (a) If either (i) the introduction of or
any change (including, without limitation, any change by way of
imposition or increase of reserve requirements other than those
referred to in the definition of "Eurodollar Reserve Percentage")
in or in the interpretation of any law or regulation or (ii) the
compliance by CIBC  or any of the other Banks with any guideline,
requirement or request from any central bank or other
governmental or quasi-governmental authority (whether or not
having the force of law), shall either (A) impose, modify or deem
applicable any reserve, assessment, special deposit or similar
requirement against letters of credit issued by, or assets held
by, or deposits in or for the account of, CIBC or any of the
other Banks or (B) impose on CIBC or any of the other Banks any
other condition regarding this Agreement, the Letter of Credit or
any Advance, and the result of any event referred to in clause
(A) or (B) above, shall be to increase the cost to any of the
Banks of issuing or maintaining the Letter of Credit or agreeing
to make or making, funding or maintaining any Advance by an
amount which such Bank reasonably deems material (which increase
in cost shall be determined by such Bank's reasonable allocation
of the aggregate of such cost increases resulting from such
event), then, upon demand by the Agent (which demand shall be
made at the direction of any of the Banks affected), the Company
shall pay to the Agent for the benefit of the Banks affected,
from time to time as specified by the Agent, additional amounts
which shall be sufficient to compensate such Banks for such
increased cost.  A certificate setting forth such increased cost
incurred by the Banks as a result of any event referred to in
clause (i) or (ii) above, and giving a reasonable explanation
thereof, submitted by the Agent, on behalf of and at the
direction of the Banks affected, to the Company, shall constitute
such demand and shall, in the absence of manifest error, be
conclusive and binding for all purposes.

          (a)       If, due to any change of interest rate on any Advance
pursuant to Section 2.6(b)(iv), any prepayment pursuant to
Section 2.8, any acceleration of maturity of the Advances
pursuant to Section 6.2, or any other reason, any Bank is subject
to a change of interest rate, or receives payments of principal,
of any Eurodollar Advance other than on the last day of the
Interest Period relating to such Advance, the Company shall,
promptly after demand by the Agent (which demand shall be made at
the direction of such Bank), pay to the Agent for the benefit of
the Banks affected any amounts required to compensate such Banks
for any additional losses, costs or expenses which they may
reasonably incur as a result of such change or payment,
including, without limitation, any loss (including loss of
anticipated profits), cost or expense incurred by reason of the
liquidation or reemployment of deposits or other funds acquired
by such Banks to fund or maintain such Eurodollar Advance.  A
certificate setting forth the amount of such additional losses,
costs or expenses and giving a reasonable explanation thereof,
submitted by the Agent, on behalf of and at the direction of the
Banks affected, to the Company, shall constitute such demand and
shall, in the absence of manifest error, be conclusive and
binding for all purposes.

          II.10       Increased Capital.  If either (i) the introduction of
or any change in or in the interpretation of any law or
regulation or (ii) compliance by any of the Banks with any
guideline or request from any central bank or other governmental
authority (whether or not having the force of law) affects or
would affect the amount of capital required or expected to be
maintained by such Bank or any corporation controlling such Bank
and such Bank determines that the amount of such capital is
increased by or based upon the existence of letters of credit (or
similar contingent obligations) then, the Company shall
immediately pay to the Agent for the benefit of the Banks
affected, from time to time as specified by the Agent at the
direction of such Banks, additional amounts sufficient to
compensate such Banks in the light of such circumstances, to the
extent that such Banks reasonably determined such capital to be
allocable to the issuance or maintenance of the Letter of Credit
(or participation therein).  A certificate as to such amounts
submitted to the Company by the Agent on behalf of and at the
direction of the Banks affected, giving a reasonable explanation
thereof, shall constitute such demand and shall, in the absence
of manifest error, be conclusive and binding for all purposes as
to the amount thereof.

          II.11       Payments and Computations.  The Company shall make
each payment hereunder not later than 12:00 Noon (New York time)
on the day when due in lawful money of the United States of
America to CIBC or the Agent, as appropriate, at its address
referred to in Section 7.2 in same-day funds.  Any amounts due to
the Banks hereunder in respect of any such payment received from
the Company shall be paid by the Agent to the Banks in lawful
money of the United States of America at their respective
addresses, as provided in Section 7.2, in same-day funds by the
close of the Business Day on which such payment is received.  If
and to the extent any such amount due to any Bank is not paid by
the Agent in a timely fashion as aforesaid, the Agent agrees to
pay interest on such unpaid amount for such Bank's account
forthwith on demand for each day from and including the date such
amount was to have been paid to such Bank to but excluding the
date such amount is paid, at a rate per annum equal to the
Federal Funds Rate.  Computations of the Prime Rate and the
Default Rate shall be made by the Agent on the basis of a year of
365 or 366 days, as the case may be, for the actual number of
days (including the first day but excluding the last day)
elapsed.  Computations of the Eurodollar Rate, the Federal Funds
Rate and the commissions and fees under Section 2.4 hereof shall
be made by the Agent on the basis of a year of 360 days for the
actual number of days (including the first day but excluding the
last day) elapsed.

          II.12       Non-Business Days.  Whenever any payment to be made
hereunder shall be stated to be due, or whenever the last day of
any Interest Period would otherwise occur, on a day which is not
a Business Day, such payment shall be made, and the last day of
such Interest Period shall occur, on the next succeeding Business
Day, and such extension of time shall in such case be included in
the computation of payment of interest, fee or commission, as the
case may be; provided, however, if such extension would cause
such payment of a Eurodollar Advance to be made and the last day
of an Interest Period for a Eurodollar Advance to occur in the
next following calendar month, such payment shall be made and the
last day of such Interest Period shall occur on the next
preceding Business Day.

          II.13       Extension of the Stated Termination Date.  Unless the
Letter of Credit shall have expired in accordance with its terms
on the Cancellation Date, at least 60 but not more than 120 days
before each May 1, commencing May 1, 1997, the Company may
request the Agent in writing (each such request being
irrevocable) to extend for one year the Stated Termination Date
(it being understood that the Company may make no more than two
such requests under this Section).  If the Company shall make
such a request, the Agent shall, no later than 40 days following
the date on which the Agent shall have received such request,
notify the Company in writing whether or not the Banks consent to
such request (such consent requiring unanimous written approval
of the Banks in their individual sole discretion) and, if all of
the Banks do so consent, the conditions of such consent
(including conditions relating to legal documentation and the
consent of the Trustee).  If the Agent shall not so notify the
Company, the Banks shall be deemed not to have consented to such
request.

          II.14       Evidence of Debt. CIBC and, as appropriate, each
other Bank shall maintain, in accordance with its usual practice
evidence of the indebtedness of the Company resulting from each
drawing under the Letter of Credit and from each Advance made
from time to time hereunder and the amounts of principal and
interest payable and paid from time to time hereunder.  In any
legal action or proceeding in respect of this Agreement, the
entries made shall, in the absence of manifest error, be
conclusive evidence of the existence and amounts of the
obligations of the Company therein recorded.

          II.15       Obligations Absolute.  The payment obligations of the
Company under this Agreement shall be unconditional and
irrevocable, and shall be paid strictly in accordance with the
terms of this Agreement under all circumstances, including,
without limitation, the following circumstances:

               (i)    any lack of validity or enforceability of the Letter of
          Credit, the Bonds, the Indenture, the Loan Agreement, the
          Custodian Agreement, the First Mortgage Bond, the First Mortgage
          Bond Indenture, the First Mortgage Bond Indenture Supplement, the
          First Mortgage Bond Delivery Agreement, the Remarketing
          Agreement, (collectively, the "Related Documents"), this
          Agreement, or any other agreement or instrument relating thereto;

               (ii)   any amendment or waiver of or any consent to departure
          from all or any of the Related Documents;

               (iii)       the existence of any claim, set-off, defense or 
          other right which the Company may have at any time against the 
          Trustee or any other beneficiary, or any transferee, of the Letter of
          Credit (or any persons or entities for whom the Trustee, any such
          beneficiary or any such transferee may be acting), any Bank, or
          any other person or entity, whether in connection with this
          Agreement, the transactions contemplated herein or in the Related
          Documents, or any unrelated transaction;

               (iv)   any statement or any other document presented under the
          Letter of Credit proving to be forged, fraudulent, invalid or
          insufficient in any respect or any statement therein being untrue
          or inaccurate in any respect;

               (v)    payment by CIBC under the Letter of Credit against
          presentation of a draft or certificate which does not comply with
          the terms of the Letter of Credit; or

                    (vi)  any other circumstance or happening
          whatsoever, whether or not similar to any of the
          foregoing.

Nothing in this Section 2.15 is intended to limit any liability
of CIBC pursuant to Section 7.6 in respect of its wilful
misconduct or gross negligence.

          II.16       First Mortgage Bond.  The Company shall cause all
obligations of the Company to reimburse CIBC with respect to any
payment under the Letter of Credit to be and remain secured,
until paid, by the First Mortgage Bonds issued to CIBC in a
principal amount equal to $18,347,124, accruing interest at a
floating rate equal to the Eurodollar Rate (subject to a cap of
12% per annum) and containing other provisions and terms and
otherwise in accordance with the First Mortgage Bond Delivery
Agreement.

IV               REPRESENTATIONS AND WARRANTIES

     existing and in good standing under the laws of the State of
     Arizona and is in compliance, in all material respects, with all

     financial condition or operations of the Company or its ability
     to perform its obligations hereunder or in connection herewith.

     contravene (i) the Company's charter or code of regulations or
     (ii) law (including, without limitation, any order, rule or
     regulation of the ACC) or any contractual restriction binding on
     or affecting the Company, and do not result in or require the
     creation of any lien, security interest or other charge or
     encumbrance (except as may be created under the Related
     Documents) upon or with respect to any of its properties.

          (c)       No authorization or approval or other action by, and no
     notice to or filing with, any governmental authority or
     regulatory body is required for the due execution, delivery and

     Document to which the Company is a party except for the ACC
     Order, which has been duly obtained, is final and in full force

     operations or prospects of the Company or the ability of the
     Company to perform its obligations hereunder or under any of the
     Related Documents or which purports to affect the legality,
     validity or enforceability of this Agreement or any Related
     Document.

          (g)       No Termination Event has occurred nor is reasonably
     expected to occur with respect to any Plan, and no contribution
     failure has occurred with respect to any Plan sufficient to give
     rise to a lien under Section 302(f) of ERISA.

          IV(ff)    Schedule B (Actuarial Information) to the
     199_ annual report (Form 5500 Series) with respect to each
     Plan, copies of which have been filed with the Internal
     Revenue Service and furnished to the Agent, is complete and
     accurate and fairly presents the funding status of such
     Plan, and since the date of such Schedule B there has been
     no material adverse change in such funding status.

          (i)       Neither the Company nor any of its Affiliates has
     incurred nor reasonably expects to incur any withdrawal liability
     under ERISA to any Multiemployer Plan.  No condition exists or
     event or transaction has occurred with respect to any Plan which
     could result in the incurrence by the Company of any material
     liability, fine or penalty (other than the liability in the
     ordinary course of business to pay benefits or make
     contributions).  Except as disclosed in Schedule 4.1(i) hereto,
     the Company has no contingent liability with respect to any post-
     retirement benefit under a welfare plan as defined in Section
     3(1) of ERISA, other than liability for continuation coverage
     described in Part 6 of subtitle B of title I of ERISA.

          (j)       The Company has filed all material tax returns
     (Federal, state and local), which to the knowledge of the
     Company, are required to be filed and paid all taxes shown
     thereon to be due, including interest and penalties, or provided
     adequate reserves for payment thereof other than such taxes that
     the Company is contesting in good faith by appropriate legal
     proceedings.

          (k)       Except as otherwise disclosed to the Agent by the
     Company in writing or as disclosed in any publicly available
     report filed by the Company with the Securities and Exchange
     Commission, in each case, prior to the date hereof, (i) all
     facilities and property (including underlying groundwater) owned
     or leased by the Company or any of its Subsidiaries have been,
     and continue to be, owned or leased by it and its Subsidiaries in
     compliance with all environmental laws, except for such failures
     to comply which would not give rise to any potential material
     liability of the Company or any of its Subsidiaries; and (ii)
     there have been no past, and, to the Company's actual knowledge,
     there are no pending or threatened (x) claims, complaints or
     notices for information received by the Company or any of its
     Subsidiaries with respect to any alleged violation of any
     environmental law, or (y) complaints or notices to the Company or
     any of its Subsidiaries regarding potential material liability
     under any environmental law, except for such alleged violations
     which would not give rise to any potential material liability of
     the Company or any of its Subsidiaries.

          (l)       All information heretofore or contemporaneously
     herewith furnished by the Company to the Agent and the Banks for
     purposes of or in connection with this Agreement and the
     transactions contemplated hereby is, and all information
     hereafter furnished by or on behalf of the Company to the Agent
     or the Banks will be, true and accurate in every material respect
     on the date as of which such information is dated or certified,
     and none of such information is or will be incomplete by omitting
     to state any material fact necessary to make such information not
     misleading in light of the circumstances in which such
     information was provided.

          (m)       The Company is not engaged in the business of extending
     credit for the purpose of purchasing or carrying margin stock,
     and no proceeds of any Advances will be used for a purpose which
     violates, or would be inconsistent with, Regulation G, U or X of
     the Board of Governors of the Federal Reserve.  Terms for which
     meanings are provided in said Regulation G, U or X or any
     regulations substituted therefor, as from time to time in effect,
     are used in this Section 4.1(n) with such meanings.

          (n)       The provisions of the First Mortgage Bond Indenture
     (including the First Mortgage Bond Indenture Supplement), the
     First Mortgage Bonds and the First Mortgage Bond Delivery
     Agreement (the "First Mortgage Documents") are effective to
     create, in favor of the Agent for the benefit of the Banks, a
     legal, valid and enforceable Lien on or in all of the "Mortgaged
     Property" (as defined in the First Mortgage Bond Indenture), and
     all necessary and appropriate recordings and filings have been
     made in all necessary and appropriate public offices so that the
     Liens created by the First Mortgage Documents constitute
     perfected Liens on or in all rights, titles, estates and
     interests of the Company in the "Mortgaged Property" (as defined
     in the First Mortgage Bond Indenture), prior and superior to all
     other Liens other than Liens permitted under subsection 12.4(d)
     and (e) of the Master Restructuring Agreement, and all necessary
     and appropriate consents to the creation and perfection of such
     Liens have been obtained.  No mortgage or financing statement or
     other instrument or recordation covering all or any part of the
     "Mortgaged Property" (as defined in the First Mortgage Bond
     Indenture) is on file in any recording office which has not been
     terminated or released, except as may have been filed in favor of
     the Agent, for the benefit of the Banks or in respect of any Lien
     permitted under subsection 12.4(d) and (e) of the Master
     Restructuring Agreement.

V                   COVENANTS OF THE COMPANY

          V.1    Affirmative Covenants.  So long as a drawing is available
under the Letter of Credit (or the Banks shall have any other
obligation to the Company thereunder) or the Banks shall have any
Commitment hereunder or the Company shall have any obligation to
pay any amount to the Banks hereunder, the Company will, unless
the Agent (with the consent of the Majority Banks) shall
otherwise consent in writing:

          (a)       Preservation of Corporate Existence, Etc.  Without
     limiting the rights of the Company under Section 5.2(d), preserve
     and maintain its corporate existence, rights (charter and
     statutory), and franchises, and its qualification to do business
     in Arizona; provided, however, that the Company shall not be
     required to maintain any right or franchise if the Board of
     Directors of the Company shall determine that the preservation
     thereof is no longer desirable in the conduct of the business of
     the Company and that the loss thereof is not disadvantageous in
     any material respect to the Company.

          (b)       Compliance with Laws, Etc.  Comply in all material
     respects with all applicable laws, rules, regulations and orders
     (including, without limitation, applicable environmental laws,
     rules, regulations and orders), such compliance to include,
     without limitation, paying before the same become delinquent all
     material taxes, assessments and governmental charges imposed upon
     it or upon its property, except to the extent that compliance
     with or payment of any of the foregoing is then being contested
     in good faith and by appropriate proceedings and against which
     adequate reserves are being maintained; provided, however, that
     any such non-compliance which will not have a material adverse
     effect on the financial condition or operations of the Company or
     its ability to perform its obligations shall not constitute a
     breach of this subsection (b).

          (c)       Visitation Rights.  Subject to contractual or statutory
     limitations regarding confidential or proprietary information, at
     any reasonable time and from time to time, permit the Agent or
     any agents or representatives thereof, to examine and make copies
     of and abstracts from the records and books of account of, and
     visit the properties of, the Company and any of its Subsidiaries
     which the Agent determines in good faith to be relevant to the
     interests of the Banks hereunder, and to discuss the affairs,
     finances and accounts of the Company and any of its Subsidiaries
     with any of their respective officers or directors; provided,
     however, that the Company reserves the right to restrict access
     to any of its facilities in accordance with reasonably adopted
     procedures relating to safety and security and provided, further,
     that anything herein to the contrary notwithstanding, such costs
     and expenses incurred by the Agent in connection with any such
     examinations, copies, abstracts, visits or discussions occurring
     or made prior to the occurrence and continuance of an Event of
     Default shall be for the account of such Bank.  Each Bank agrees
     to use its best efforts to ensure that any information concerning
     the Company or any of its Subsidiaries obtained by such Bank
     pursuant to this Section 5.1(c) that is not contained in a report
     or other document filed with the Securities and Exchange
     Commission distributed by the Company or any of its Subsidiaries
     to its shareholders or otherwise available to the public
     generally, will to the extent permitted by law and except as may
     be required by valid subpoena or in the normal course of business
     operations of such Bank be treated confidentially by such Bank
     and will not be distributed or otherwise made available by such
     Bank to any person or entity other than bank examiners and the
     employees, auditors, counsel, authorized agents or
     representatives of such Bank or the Agent.

          (d)       Keeping of Books.  Keep proper books of record and
     account, in which appropriate entries shall be made of all
     financial transactions and the assets and business of the Company

     of the Banks the following:

sentences of Section 7.15 hereof, no amendment or waiver of any
provision of this Agreement, nor consent to any departure by the
Company therefrom, shall in any event be effective unless the
same shall be in writing and signed by the Agent (with the
consent of the Majority Banks) and then any such waiver or
consent shall be effective only in the specific instance and for
the specific purpose for which given.

          VII.2       Notices, Etc.  All notices and other communications
provided for hereunder shall be in writing (including telegraphic
communication) and mailed, telecopied, telexed, telegraphed or

to the provisions of Article II shall not be effective until
received by CIBC or the Agent (as the case may be).

          VII.3       No Waiver; Remedies.  No failure on the part of any
Bank or the Agent to exercise, and no delay in exercising, any
right hereunder shall operate as a waiver thereof; nor shall any
single or partial exercise of any right hereunder preclude any
other or further exercise thereof or the exercise of any other
right.  The remedies herein provided are cumulative and not
exclusive of any remedies provided by law.

          VII.4       Right of Set-off; Sharing of Payments.  (a) Upon the
occurrence and during the continuance of any Event of Default,
each Bank is hereby authorized at any time and from time to time,
to the fullest extent permitted by law, to set off and apply any
and all deposits (general or special, time or demand, provisional
or final) at any time held and other indebtedness at any time
owing by such Bank to or for the credit or the account of the
Company against any and all of the obligations of the Company now
or hereafter existing under this Agreement, up to its pro rata
share thereof, according to the amount of its Percentage,
irrespective of whether or not such Bank shall have made any
demand hereunder and although such obligations may be contingent
or unmatured.

          (a)       Each Bank agrees promptly to notify the Company after
any such set-off and application referred to in subsection (a)
above; provided that the failure to give such notice shall not
affect the validity of such set-off and application.  The rights
of the Banks under this Section are in addition to other rights
and remedies (including, without limitation, other rights of set-
off) which the Banks may have.

          (b)       If any Bank shall obtain any payment or other recovery
(whether voluntary, involuntary, by application of setoff or
otherwise) on account of any Advance (other than pursuant to the
terms of Sections 2.09 and 2.10) in excess of its pro rata share
of payments then or therewith obtained by all Banks, such Bank
shall purchase from the other Banks such participations in
Advances made by them as shall be necessary to cause such
purchasing Bank to share the excess payment or other recovery
ratably with each of them; provided, however, that if all or any
portion of the excess payment or other recovery is thereafter
recovered from such purchasing Bank, the purchase shall be
rescinded and each Bank which has sold a participation to the
purchasing Bank shall repay to the purchasing Bank the purchase
price to the ratable extent of such recovery together with an
amount equal to such selling Bank's ratable share (according to
the proportion of

               (i)       the amount of such selling Bank's required repayment 
          to the purchasing Bank, to

               (ii)      the total amount so recovered from the purchasing 
          Bank) of any interest or other amount paid or payable by the 
          purchasing Bank in respect of the total amount so recovered.  The 
          Company agrees that any Bank so purchasing a participation from 
          another Bank pursuant to this Section 7.4(c) may, to the fullest 
          extent permitted by law, exercise all its rights of payment 
          (including pursuant to Section 7.4(a) and (b) with respect to such
participation as fully as if such Bank were the direct creditor
of the Company in the amount of such participation.  If under any
applicable bankruptcy, insolvency or other similar law, any Bank
receives a secured claim in lieu of a setoff to which this
Section applies, such Bank shall, to the extent practicable,
exercise its rights in respect of such secured claim in a manner
consistent with the rights of the Banks entitled under this
Section to share in the benefits of any recovery on such secured
claim.

          VII.5       Indemnification.  The Company hereby indemnifies and
holds the Banks and the Agent harmless from and against any and
all claims, damages, losses, liabilities, penalties, costs and
expenses which any Bank or the Agent may incur or which may be
claimed against any Bank or the Agent by any Person:

          (a)       by reason of any inaccuracy or alleged inaccuracy in
     any material respect, or any untrue statement or alleged untrue
     statement of any material fact, contained in the Preliminary
     Official Statement or the Official Statement or any amendment or
     supplement thereto, or by reason of the omission or alleged
     omission to state therein a material fact necessary to make such
     statements, in the light of the circumstances under which they
     were made, not misleading; or

          (b)       by reason of or in connection with the execution,
     delivery or performance of the Bonds, the Indenture, or the Loan
     Agreement, or any transaction contemplated by the Indenture or
     the Loan Agreement, other than as specified in subsection (c)
     below; or

          (c)       by reason of or in connection with the execution and
     delivery or transfer of, or payment or failure to make payment
     under, the Letter of Credit or any documents or instruments in
     connection therewith; provided, however, that the Company shall
     not be required to indemnify any Bank or the Agent pursuant to
     this Section 7.5(c) for any claims, damages, losses, liabilities,
     costs or expenses to the extent caused by (i) CIBC's wilful
     misconduct or gross negligence, as determined by a court of
     competent jurisdiction, in determining whether documents
     presented under the Letter of Credit comply with the terms of the
     Letter of Credit or (ii) CIBC's wilful or grossly negligent
     failure, as determined by a court of competent jurisdiction, to
     make lawful payment under the Letter of Credit after the
     presentation to it by the Trustee of a draft and certificate
     strictly complying with the terms and conditions of the Letter of
     Credit.

Nothing in this Section 7.5 is intended to limit the Company's
obligations contained in Article II.  Without prejudice to the
survival of any other obligation of the Company hereunder, the
indemnities and obligations of the Company contained in this
Section 7.5 shall survive the payment in full of amounts payable
pursuant to Article II and the termination of the Letter of
Credit.

          VII.6       Liability of the Banks.  The Company assumes all
risks of the acts or omissions of the Trustee and any other
beneficiary or transferee of the Letter of Credit with respect to
its use of the Letter of Credit.  Neither the Banks, the Agent
nor any of their respective officers or directors shall be liable
or responsible for:  (a) the use which may be made of the Letter
of Credit or any acts or omissions of the Trustee and any other
beneficiary or transferee in connection therewith; (b) the
validity, sufficiency or genuineness of documents, or of any
endorsement thereon, even if such documents should prove to be in
any or all respects invalid, insufficient, fraudulent or forged;
(c) payment by CIBC against presentation of documents which do
not comply with the terms of the Letter of Credit, including
failure of any documents to bear any reference or adequate
reference to the Letter of Credit; or (d) any other circumstances
whatsoever in making or failing to make payment under the Letter
of Credit, except that the Company shall have a claim against
CIBC, and CIBC shall be liable to the Company, to the extent of
any direct, as opposed to consequential, damages suffered by the
Company which the Company proves were caused by (i) CIBC's wilful
misconduct or gross negligence, as determined by a court of
competent jurisdiction, in determining whether documents
presented under the Letter of Credit comply with the terms of the
Letter of Credit or (ii) CIBC's wilful or grossly negligent
failure, as determined by a court of competent jurisdiction, to
make lawful payment under the Letter of Credit after the
presentation to it by the Trustee of a draft and certificate
strictly complying with the terms and conditions of the Letter of
Credit.  In furtherance and not in limitation of the foregoing,
CIBC may accept (documents that appear on their face to be in
order (whether original documents or copies thereof, including
but not limited to, facsimile copies), without responsibility for
further investigation, regardless of any notice or information to
the contrary.

          VII.7       Costs, Expenses and Taxes.  The Company agrees to pay
on demand all reasonable costs and expenses in connection with
the preparation, execution, delivery, filing, recording, and
administration of this Agreement, the Custodian Agreement and any
other documents which may be delivered in connection with this
Agreement (including any amendments or waivers of, or consents to
depart from, any provision hereof executed in accordance herewith
at any time or from time to time), including, without limitation,
(A) the reasonable fees and out-of-pocket expenses of counsel for
the Agent and CIBC, and local counsel who may be retained by said
counsel, with respect thereto and with respect to advising the
Agent and CIBC as to their respective rights and responsibilities
under this Agreement and all costs and expenses (including
counsel fees and expenses) in connection with (i) the enforcement
(whether through negotiations, legal proceedings or otherwise) of
this Agreement and such other documents which may be delivered in
connection with this Agreement or (ii) any action or proceeding
relating to a court order, injunction, or other process or decree
restraining or seeking to restrain CIBC from paying any amount
under the Letter of Credit and (B) all costs and expenses of any
Bank (including fees and expenses of counsel to such Bank) in
connection with enforcement (whether through negotiations, legal
proceedings or otherwise) of this Agreement and such other
documents which may be delivered in connection with this
Agreement.  In addition, the Company shall pay any and all stamp
and other taxes and fees payable or determined to be payable in
connection with the execution, delivery, filing and recording of
this Agreement or the Letter of Credit or any such other
documents, and agrees to save the Banks harmless from and against
any and all liabilities with respect to or resulting from any
delay in paying or omission to pay such taxes and fees.
Notwithstanding the foregoing, the Company's obligation in
respect of the fees of Agent's counsel in respect of the
preparation and initial closing under this Agreement shall be
limited to $15,000.

          VII.8       Binding Effect.  This Agreement shall become
effective when it shall have been executed and delivered by the
Company, the Agent and the Banks and thereafter shall be binding
upon and inure to the benefit of the Company, the Agent and the
Banks and their respective successors and assigns, except that
the Company shall not have the right to assign its rights
hereunder or any interest herein without the prior written
consent of the Agent.  CIBC may assign to one or more banks or
other entities all or any part of, or may grant participations to
one or more banks or other entities in all or any part of, or any
interest (undivided or divided) in, CIBC's rights and benefits
under this Agreement, and to the extent of any such assignment or
participation (unless otherwise stated therein) the assignee or
purchaser of such assignment or participation shall, to the
fullest extent permitted by law, have the same rights and
benefits hereunder as it would have if such assignee were a Bank
hereunder.

          VII.9       Severability.  Any provision of this Agreement which
is prohibited, unenforceable or not authorized in any
jurisdiction shall, as to such jurisdiction, be ineffective to
the extent of such prohibition, unenforceability or non-
authorization without invalidating the remaining provisions
hereof or affecting the validity, enforceability or legality of
such provision in any other jurisdiction.

          VII.10      Governing Law.  This Agreement shall be governed by,
and construed in accordance with, the internal laws of the State
of New York.

          VII.11      Headings.  Section headings in this Agreement are
included herein for convenience of reference only and shall not
constitute a part of this Agreement for any other purpose.

          VII.12      Subparticipation.  Subject to Section 7.8, no Bank's
participation may be subdivided or transferred without the
Agent's prior written consent (which consent shall not be
unreasonably withheld); except that each Bank may, with notice to

participation without consent of the Agent if such subdivision or
transfer is made exclusively with or to a branch of such Bank
located in any State of the United States and subject to
jurisdiction of the state and federal courts therein.

          VII.13      Acknowledgements and Agreements by the Banks.  Each
Bank expressly acknowledges and agrees that:  (a) it has received
a copy of this Agreement, the Official Statement, the Indenture,
the Loan Agreement and such other documents in connection with
this Agreement and the Letter of Credit as it has deemed
appropriate to make its own credit analysis and decision to enter
into this Agreement; (b) such Bank, independently and without
reliance upon CIBC or the Agent, has made its own appraisal of
the creditworthiness of the Company and any and all other
obligors, has made a commercial banking decision to purchase its
participation and did take such care on its own behalf as would
have been the case if it were a direct party to the Letter of
Credit; (c) neither CIBC nor the Agent has made or does make any
representations or warranties or assumes any responsibility with
respect to the validity, genuineness, due authorization,
execution, delivery, legality, sufficiency, enforceability or
collectibility of any document related to the Letter of Credit or
any Advance (including, without limitation, this Agreement or any
other agreement, security agreement, guaranty, statement or
certificate delivered in connection therewith) or with respect to
the validity, genuineness, enforceability, collectibility,
existence or worth of any collateral securing the same or
guarantees thereof; (d) CIBC and the Agent assume no
responsibility for (i) any statement, warranty, representation,
or certification made in, or in connection with, any document
relative to the Letter of Credit or Advances, (ii) the filing,
recording, or taking of any action with respect to any document
relative to the Letter of Credit or Advances or any security
therefor, or (iii) the financial condition of the Company or any
other obligor with respect to the Letter of Credit or Advances or
the performance or observance by the Company or any other obligor
with respect to the Letter of Credit or Advances of their
obligations; and (e) the sale of the participation hereunder does
not constitute the sale of a "security" for purposes of the
Securities Act of 1933 and the Securities and Exchange Act of
1934.

          VII.14      Authorization.  Each Bank authorizes the Agent to act
on behalf of such Bank to the extent provided herein or in any
Related Document, the Letter of Credit or any other document or
instrument delivered hereunder or in connection herewith, and to
take such other action as may be reasonably incidental thereto.

          VII.15      Action by the Agent.  Each Bank expressly understands
and agrees that (a) the Agent may use its discretion with respect
to exercising or refraining from exercising any rights which it
may have or taking or refraining from taking any actions it may
be entitled to take in connection with the Letter of Credit,
Advances, this Agreement or any other document related to the
Letter of Credit or Advances or any collateral therefor or any
obligor or beneficiary thereunder; and (b) in exercising such
discretion, the Agent will use the same care to protect the
interest of the Banks as it would if the Agent were the holder of
the Banks' interests, and that, so long as the Agent exercises
such care, it shall not be under any liability to the Banks
except in the instance of the Agent's gross negligence or willful
misconduct (without limiting the foregoing, the Agent may consult
with legal counsel, independent public accountants, and experts
selected by it, and will not be liable for any action that it
takes or does not take, in good faith, in accordance with the
advice of such counsel, accountants or experts, and the Agent may
act in reliance on any notice, consent or other instrument or
writing which it believes to be genuine or to have been presented
by a proper Person).  Each Bank further expressly understands and
agrees that the Agent may, with the consent of the Majority
Banks, agree to any amendment, modification, waiver, termination,
release or consent with respect to the Letter of Credit,
Advances, this Agreement or any document (including, without
limitation, any security agreement or guaranty) relative to the
Letter of Credit, Advances or this Agreement or any Related
Document, or take, or refrain from taking, any action with
respect thereto, except that the Agent will not, without the
consent of all of the Banks, agree to any extension of the Letter
of Credit (or this Agreement in connection therewith), reduction
of the effective fee rate or interest rate payable to the Banks
in connection with the Letter of Credit or Advances, forgiveness
or postponement of any reimbursement obligation in respect of the
Letter of Credit or any principal of or interest on the Advances
payable to the Banks, or any release of Collateral under the
Custodian Agreement.  If the Agent requests the consent of the
Banks to an amendment, modification, waiver, release or consent
and any Bank does not respond within ten (10) days of CIBC's
written request, such Bank shall be deemed not to have given its
consent thereto.  If a Bank fails to consent to any amendment,
modification, waiver, release or consent which requires its
consent, CIBC shall have the right, but not the obligation, to
terminate and repurchase such Bank's participation in the Letter
of Credit and all Advances or, in its discretion, in only the
Advances under the Letter of Credit affected by such change, at
such time, for a purchase price equal to the Bank's proportionate
share of the then unpaid principal balance of the outstanding
Advances, if any, being repurchased (reduced by an amount equal
to such Bank's Percentage of any such Advance or portion thereof
with respect to which such Bank has not, as of the time of such
repurchase, reimbursed CIBC in full in accordance with Section
2.7(a)), together with interest, fees and other amounts accrued
with respect thereto, and terminate the Bank's obligations
hereunder with respect to the Letter of Credit and/or the
repurchased Advances, as appropriate.

          VII.16         Indemnification by the Banks.  The Agent shall not
be required to do any act hereunder or under any Related
Document, the Letter of Credit, or any other document or
instrument delivered hereunder or in connection herewith or take
any action toward the execution or enforcement of the agency
hereby created, or to prosecute or defend any suit in respect of
this Agreement, the Related Documents, the Letter of Credit, or
any collateral security, or other documents in connection with
the foregoing, unless indemnified to its satisfaction by the
Banks, pro rata, in accordance with their respective Percentages,
against loss, cost, liability, and expense.  If any indemnity
furnished to the Agent for any purpose shall, in the opinion of
the Agent, be insufficient or become impaired, the Agent may call
for additional indemnity and not commence or cease to do the acts
indemnified against until such additional indemnity is furnished.

          VII.17         Exculpation of the Agent.  Neither the Agent nor
any of its directors, officers, employees or agents shall (i) be
responsible for any recitals, representations or warranties
contained in, or for the execution, validity, genuineness,
effectiveness or enforceability of, this Agreement, any Related
Document, the Letter of Credit, or any other instrument or
document delivered hereunder or in connection herewith, (ii) be
responsible for the validity, genuineness, Related Document, the
Letter of Credit, or any other instrument or document delivered
hereunder or in connection herewith, (ii) be responsible for the
validity, genuineness, perfection, effectiveness, enforceability,
existence, value or enforcement of any Collateral or other
collateral security, (iii) be under any duty to inquire into or
pass upon any of the foregoing matters, or to make any inquiry
concerning the performance by the Company or any other obligor of
its obligations, (iv) be responsible to verify that any schedule,
certificate, statement, report, notice or other writing which is
required to be delivered by the Company to the Banks has in fact
been delivered to the Banks, (v) be responsible for the content
of any schedule, certificate, statement, report, notice or other
writing which is required to be delivered by the Company to the
Banks including, without limitation, any such writing which in
fact is not delivered to the Banks, or (vi) in any event, be
liable as such for any action taken or omitted by it or them,
except, in each case, for its or their own gross negligence or
willful misconduct.  The agency hereby created shall in no way
impair or affect any of the rights and powers of, or impose any
duties or obligations upon, the Agent in its individual capacity.

          VII.18      Knowledge.  The Agent shall be entitled to assume
that no Event of Default or event or circumstance that with
notice or lapse of time or both would constitute an Event of
Default exists, absent actual knowledge thereof.

          VII.19      Resignation.  The Agent may resign as such at any
time upon at least 30 days' prior notice to the Company and the
Banks.  In the event of any such resignation, the Banks shall as
promptly as practicable appoint a successor Agent with the
consent of those Banks whose Percentages in the aggregate are
greater than 50%.  After any resignation pursuant to this Section
7.19, the provisions of this Agreement relating to
indemnification and limitation of the liability of the Agent,
including without limitation Sections 7.13, 7.15, 7.16 and 7.17,
shall inure to the benefit of the retiring Agent as to any
actions taken or omitted to be taken by it while it was Agent
hereunder.

          VII.20         Submission To Jurisdiction; Waivers.  The Company
hereby irrevocably and unconditionally:

          (a)       submits for itself and its property in any legal action
     or proceeding relating to this Agreement, the First Mortgage
     Documents and the Custodian Agreement, or for recognition and
     enforcement of any judgment in respect thereof, to the non-
     exclusive general jurisdiction of the Courts of the State of New
     York in the County of New York, the courts of the United States
     of America for the Southern District of New York, and appellate
     courts from any thereof;

          (b)       consents that any such action or proceeding may be
     brought in such courts and waives any objection that it may now
     or hereafter have to the venue of any such action or proceeding
     in any such court or that such action or proceeding was brought
     in an inconvenient court and agrees not to plead or claim the
     same;

          (c)       agrees that service of process in any such action or
     proceeding may be effected by mailing a copy thereof by
     registered or certified mail (or any substantially similar form
     of mail), postage prepaid, to the Company at its address set
     forth in Section 7.2 or at such other address of which the Agent
     shall have been notified pursuant thereto; and

          (d)       agrees that nothing herein shall affect the right to
     effect service of process in any other manner permitted by law or
     shall limit the right to sue in any other jurisdiction.

Attention:  Corporate Trust Administration

Dear Sir or Madam:

          We hereby issue our Irrevocable Letter of Credit No.
U-96-0623, at the request and for the account of Tucson Electric
Power Company (the "Company"), in your favor, as Trustee under
the Indenture of Trust, dated as of May 1, 1996 (the
"Indenture"), between the Coconino County, Arizona Pollution
Control Corporation (the "Issuer") and you, as Trustee, pursuant
to which $16,700,000 in aggregate principal amount of the
Issuer's Pollution Control Revenue Bonds, 1996 Series A (Tucson
Electric Power Company Project) (the "Bonds"), are to be issued,
this Letter of Credit being in the total amount of $18,347,124
(subject to adjustment as provided below).

          This Letter of Credit shall be effective immediately
and shall expire upon the earliest to occur of (i) April 30,
1999, (ii) the date on which we receive a written and completed
certificate signed by you in the form of Exhibit 1 or Exhibit 3
attached hereto, stating that the drawing thereunder is the final
drawing under this Letter of Credit and that, upon the honoring
of such drawing, this Letter of Credit will expire in accordance
with its terms, and (iii) the date upon which we receive a
written certificate signed by you and stating therein that either
(a) no Bonds are "Outstanding" (as defined in the Indenture) or
(b) this Letter of Credit is being "Terminated" (as defined in
the Indenture) without a mandatory purchase of the Bonds (such
earliest date being the "Cancellation Date").

          The aggregate amount which may be drawn under this
Letter of Credit, subject to reductions in amount and
reinstatement as provided below, is $18,347,124, of which the
aggregate amounts set forth below may be drawn as indicated.

                    (i)  An aggregate amount not exceeding
          $16,700,000, as such amount may be reduced and restored
          as provided below, may be drawn in respect of payment
          of principal of the Bonds (or the portion of the
          purchase price of Bonds corresponding to principal)
          (the "Principal Component").

                    (ii)  An aggregate amount not exceeding
          $1,647,124, as such amount may be reduced and restored
          as provided below, may be drawn in respect of the
          payment of up to 300 days' interest on the principal
          amount of the Bonds computed at a maximum rate of 12%
          per annum (or the portion of the purchase price of
          Bonds corresponding thereto) (the "Interest
          Component").

          The Principal Component and the Interest Component
shall be reduced effective upon our receipt of a certificate in
the form of Exhibit 4 attached hereto completed in strict
compliance with the terms hereof.

          The Principal Component and the Interest Component
shall be reduced immediately following our honoring of any
certificate requesting a drawing hereunder, in each case by an
amount equal to the respective component of the amount specified
in such certificate.  The presentation of a certificate
requesting a drawing hereunder, in strict compliance with the
terms hereof, shall be a "Drawing"; a Drawing in respect of a
regularly scheduled interest payment or payment of principal of
and interest on the Bonds upon scheduled or accelerated maturity
shall be a "Regular Drawing"; a Drawing to pay principal of and
interest on Bonds upon redemption of the Bonds in whole or in
part or to pay the purchase price of the Bonds in accordance with
Section 2.02(h)(iv) of the Indenture shall be a
"Redemption/Mandatory Tender Upon Default Drawing"; and a Drawing
to pay the purchase price of Bonds in accordance with Section
2.02(g) or (h) of the Indenture shall be a "Tender Drawing".

          On the eighth day following any Drawing hereunder
against the Interest Component (other than the amount drawn
pursuant to a Redemption/Mandatory Tender Upon Default Drawing in
respect of the payment of interest accrued on the Bonds) the
amount so drawn shall be automatically restored to the Interest
Component (if not previously restored pursuant to the following
paragraph) unless you shall have received written notice from us
prior to such day that we will not reinstate the Letter of Credit
in the amount of such drawing because we have not been reimbursed
in respect of such Drawing or because an "Event of Default" under
the Letter of Credit and Reimbursement Agreement dated as of May
1, 1996 between the Company and us, as it may be amended from
time to time (the "Reimbursement Agreement") has occurred and is
continuing.

          Upon our having been reimbursed by or for the account
of the Company in respect of any Regular Drawing for the payment
of interest on the Bonds or in respect to any Tender Drawing,
together with interest, if any, owing thereon pursuant to the
Reimbursement Agreement, the Principal Component and the Interest
Component, respectively, shall be restored in the same proportion
as the applicable Drawing.  Upon your telephone request, we will
confirm reinstatement pursuant to this paragraph.

          Funds under this Letter of Credit are available to you
against the appropriate certificate specified below, duly
executed by you and appropriately completed.

or  in connection with the enforcement or administration of  this
Agreement   or   the  Reimbursement  Agreement,  in   each   case
irrespective of whether the obligation to pay any such amount  is
direct or indirect, absolute or contingent, joint or several, due
or  not  due, liquidated or unliquidated, arises by operation  of
law  or  otherwise or is from time to time reduced and thereafter
reincurred.   To the extent any payment made with respect  to  an
Obligation  is rescinded or recovered or is otherwise avoided  or
must  be  restored  under  or  by reason  of  any  bankruptcy  or
insolvency  proceedings of the Company or  any  other  Person  or
otherwise,  the  amount of such payment so rescinded,  recovered,
restored or avoided shall again constitute an Obligation,  as  if
such payment had never been made.

     "Pledged Bond" means any Bond held at any time by the Tender
Agent pursuant to Section 13.01 of the Indenture.

      "Remarketing  Agreement"  means the  Remarketing  Agreement
between the Company and the Remarketing Agent, as the same may be
amended  from time to time, and any remarketing agreement between
the Company and a successor Remarketing Agent.

                                II

                       SECURITY INTEREST


     II.1   Grant of Security Interest.  As security for the due and
punctual payment in full of each of the Obligations, the  Company
hereby  grants to CIBC (on behalf of and for the benefit  of  the
Banks, pro rata, in accordance with their respective Percentages)
a   continuing  first  lien  on  and  security  interest  in  the
Collateral.

     II.2   Interest Continuing and Absolute.  Until payment in full
of  all  the  Obligations has been indefeasibly  made  after  the
Cancellation  Date,  the  security  interest  hereunder  in   the
Collateral  shall continue in full force and effect, and  it  and
the   Company's   obligations  hereunder   shall   be   effective
irrespective of any illegality, invalidity or unenforceability of
the  Bonds,  the  Letter of Credit, the Reimbursement  Agreement,
this Agreement or any other Related Document.

     II.3    Perfection.  The Company shall perfect the  security
interest  hereunder in the Collateral (a) in the case of  Pledged
Bonds,  by  delivering  or causing to be delivered  such  Pledged
Bonds to the Custodian, (b) in the case of any other certificated
securities  and cash proceeds forming part of the Collateral,  by
delivering  such  Collateral  to  CIBC,  (c)  in  the   case   of
uncertificated  securities forming part  of  the  Collateral,  by
registering such securities in the name of CIBC, or  (d)  by  any
other  method  permitted by the Uniform  Commercial  Code  as  in
effect  in  the State of New York on the date of such perfection.
All  steps  necessary for such perfection shall be taken  by  the
Company,  in  the case of each Pledged Bond forming part  of  the
Collateral, on the day such Bond becomes a Pledged Bond  and,  in
the  case  of  proceeds,  uncertified securities  and  any  other
Collateral, immediately.  The Company shall promptly notify  CIBC
of  any  Collateral delivered to the Custodian and of  any  steps
taken   to  perfect  the  security  interest  hereunder  in   the
Collateral pursuant to Section 2.3(c) or (d) hereof.


                                III

                 REPRESENTATIONS AND WARRANTIES

     III.1        Representations  and Warranties.   The  Company
represents and warrants to CIBC and the Custodian and, so long as
any   of   the  Obligations  remain  unpaid,  shall   be   deemed
continuously to represent and warrant to CIBC and the  Custodian,
as follows:

     (a)       At the time of delivery to CIBC or the Custodian of any
Collateral, the Company will have good and marketable  title  to,
and  be the sole owner of, such Collateral, free and clear of all
liens  and  other encumbrances, other than the security  interest
created   hereby,  the  security  interest  hereunder   in   such
Collateral  shall have been perfected and no financing  statement
or  other instrument with respect to any of the Collateral  shall
have  been and continue to be recorded, registered or filed,  and
no security agreement with respect to any of the Collateral shall
have  been  executed by the Company, other than with  respect  to
such  security interest in favor of CIBC (for the benefit of  the
Banks) as provided in Section 2.1 hereof.

     (b)       CIBC (on behalf of the Banks as aforesaid) has a valid,
first and prior perfected security interest in the Collateral.

     (c)       The Collateral may be properly pledged hereunder.

     (d)       No consents or approvals of any Person are required for
the  execution, delivery and performance by the Company  of  this
Agreement, the assignment and transfer by the Company of  any  of
the  Collateral  to  CIBC hereunder, or the  subsequent  sale  or
transfer of the Collateral by CIBC pursuant to the terms hereof.

     (e)       This Agreement has been authorized by all necessary
corporate action, duly executed and delivered by the Company, and
constitutes a legal, valid and binding obligation of the Company,
enforceable against the Company in accordance with its terms.


                                IV

                           COVENANTS

          IV.1   Protection of CIBC's Security Interest.  The Company
hereby  covenants and agrees that it shall defend its  title  to,
and  the  security interest hereunder in, the Collateral  against
all  claims  of all other Persons, and shall keep the  Collateral
free  from  all liens and encumbrances (other than  the  security
interest hereunder) and pay or cause to be paid promptly when due
all  taxes, fees, assessments and other charges now or  hereafter
imposed on or in respect of any of the Collateral.

          IV.2   Sale of Collateral.  The Company hereby covenants and
agrees  that it shall not, without the prior written  consent  of
CIBC  (given  with  the  consent of the  Majority  Banks),  sell,
transfer  or otherwise dispose of, or permit any other Person  to
sell, transfer or otherwise dispose of, any of the Collateral  or
any  of the Company's interests therein except in accordance with
the  terms  of this Agreement, the Indenture and the  Remarketing
Agreement.   The  receipt  by CIBC of all  or  any  part  of  the
proceeds of any sale, transfer or other disposition of any of the
Collateral,  except in accordance with the prior sentence,  shall
not  be  deemed or construed to be a consent by CIBC to any  such
sale, transfer or other disposition.

          IV.3   Further Assurances.  The Company hereby covenants and
agrees that it shall execute and deliver to CIBC or the Custodian
such  assignments and other documents and instruments, and  shall
take  all  other  action  relating  to  the  Collateral  and  the
preservation,   protection  or  perfection  of  CIBC's   security
interest therein, as CIBC or the Custodian may request,  and  the
Company  shall  not  file  or permit to be  filed  any  financing
statement (or amendment or continuation statement) or execute any
security  agreement with respect to any of the Collateral  unless
it  names CIBC (on behalf of the Banks as aforesaid) as the  only
secured  party.   To  the extent permitted by  law,  the  Company
hereby irrevocably appoints CIBC as its attorney-in-fact (without
requiring  CIBC  to act as such) to perform all  acts  that  CIBC
deems appropriate to preserve, protect and perfect its continuing
security interest in the Collateral or to preserve or protect the
Collateral,  and  the  Company  and  all  other  parties   hereto
acknowledge  and agree that such appointment is coupled  with  an
interest.


                                V

                REMEDIES  UPON  THE OCCURRENCE  OF  AN  EVENT  OF
          DEFAULT

          V.1    Default Remedies.  If an Event of Default under the
Reimbursement Agreement shall occur and be continuing, CIBC shall
be  entitled  to  exercise and shall, at  the  direction  of  the
Majority  Banks, exercise any one or more (at the  discretion  of
CIBC  and/or such Majority Banks, as appropriate, at one or  more
times) of the following remedies:

          (a)       CIBC shall have the right to receive the Collateral, if
     any, then held by the Custodian, the Remarketing Agent or any
     other Person, endorse, assign or deliver in its own name or the
     name  of  the Company any and all checks, drafts  and  other
     instruments  for the payment of money, securities  or  other
     property relating to or constituting part of the Collateral, and
     cause the Collateral to be registered in the name of CIBC or its
     designee, and the Company hereby waives presentment, protest and
     notice  of  nonpayment of any instrument  so  endorsed.   In
     furtherance of the foregoing, the Company hereby irrevocably
     appoints CIBC, or any of its officers or designees, the Company's
     lawful attorney-in-fact (without requiring CIBC so to act), with
     power of substitution, in the name of the Company or in the name
     of CIBC (i) to endorse the name of the Company upon any of the
     Collateral,  including proceeds, and to  cause  any  of  the
     Collateral to be registered in the name of CIBC (on behalf of the
     Banks as aforesaid) or its designee; (ii) to demand, collect,
     receive payment of, receipt for and give discharges and releases
     of any of the Collateral; (iii) to commence and prosecute any and
     all actions or proceedings at law or in equity in any court to
     collect or otherwise realize on any of the Collateral to enforce
     any  rights  in  respect thereof; (iv) to initiate,  settle,
     compromise, compound, adjust or defend any actions, suits or
     proceedings relating or pertaining to any of the Collateral; and
     (v) to sell, transfer, assign, discount, negotiate or otherwise
     deal in all or any portion of the Collateral or the proceeds
     thereof and generally to perform all other acts necessary or
     desirable  to  realize on, and obtain the benefits  of,  the
     Collateral and otherwise to carry out the intention of  this
     Agreement, as fully and effectively as though CIBC were  the
     absolute owner thereof, and the Company hereby ratifies  and
     confirms all that CIBC shall do by virtue of this appointment.
     CIBC shall not, under any circumstances, have any liability for
     any error or omission made in the settlement, collection  or
     payment or other disposition of any or all of the Collateral or
     of any instrument received in payment there for.

          (b)       CIBC may sell or cause to be sold, in one or more
     sales, at such price as CIBC may deem adequate, in its  sole
     discretion, and for cash or on credit or for future delivery,
     with or without assumption of any credit risk, all or any portion
     of the Collateral, at public or private sale, without demand of
     performance or notice of intention to sell or of time or place of
     sale (except such notice as may be required by applicable statute
     and  cannot  be waived), and CIBC and the Banks may  be  the
     purchaser of all or any portion of the Collateral  so  sold;
     provided, however, that CIBC shall first give notice to  the
     Trustee that an Event of Default has occurred and is continuing.
     If any Pledged Bonds are sold pursuant to this subsection (b)
     (unless sold on a basis that would exclude such Pledged Bond from
     the benefit of the Letter of Credit), CIBC shall reinstate the
     Letter of Credit to the full amount of principal and 300 days'
     interest on the principal amount at 12% per annum for any such
     Pledged Bonds sold; provided, however, that such reinstatement
     shall not be deemed to constitute a waiver by CIBC of any of its
     rights under Section 6.02 of the Reimbursement Agreement.  The
     purchaser(s)  at  any  such sale shall thereafter  hold  the
     Collateral so sold absolutely, free from any claim or  right
     whatsoever, including any equity of redemption, of the Company.
     Any  such  demand, notice, claim, right or equity is  hereby
     expressly waived and released by the Company.  Without limiting
     the foregoing, if any such notice of the time or place of sale is
     so required, the Company agrees that CIBC need not give more than
     ten days' notice of the time and place of any public sale or of
     the time after which a private sale or other intended disposition
     is to take place and that such notice is reasonable notification
     of such matters.  Neither CIBC nor any Bank shall, under any
     circumstances, incur any liability as a result of the sale of the
     Collateral  or  any  part thereof at any sale  conducted  in
     accordance with the provisions of this Agreement.  The Company
     hereby waives any claims against CIBC or the Banks arising by
     reason of the fact that the price at which the Collateral may
     have been sold at any private sale was less than the price which
     might have been obtained at a public sale or was less than the
     aggregate principal amount of the Pledged Bonds or the then total
     unpaid Obligations.

          (c)       The Company recognizes that CIBC may not deem it
     desirable to effect a public sale of any or all of the Pledged
     Bonds or otherwise but may deem it desirable to resort to one or
     more private sales thereof to a restricted group of purchasers
     who will be obliged to agree, among other things, to acquire such
     securities for their own account for investment and not with a
     view to the distribution or resale thereof.  CIBC shall be under
     no obligation to delay a sale of any of the Pledged Bonds for the
     period of time necessary to permit the Issuer to register them
     for public sale under the Securities Act of 1933, as amended (the
     "Act"), or under applicable state securities laws, even should
     the Issuer agree to do so.

          (d)       The Company shall do or cause to be done all such other
     acts and things as may be deemed necessary or desirable by CIBC
     to make such sale or sales of any portion or all of the Pledged
     Bonds valid and binding and in compliance with all applicable
     laws, regulations, orders, writs, injunctions, decrees or awards
     of   any   and   all  courts,  arbitrators  or  governmental
     instrumentalities, domestic or foreign, having jurisdiction over
     any such sale or sales, including registering such Bonds under
     the Act, or any state securities laws (to the extent necessary,
     in CIBC's judgment), all at the Company's expense.

          (e)       The Company acknowledges that a breach of any of the
     covenants contained in this Article will cause irreparable injury
     to CIBC  (and the Banks) and that CIBC (on behalf of the Banks as
     aforesaid) has no adequate remedy at law in respect of any such
     breach and, as a consequence, agrees that each and every covenant
     contained  in this Article shall be specifically enforceable
     against the Company, and the Company hereby waives and agrees not
     to assert any defenses against an action for specific performance
     of such covenants except for a defense that no Event of Default
     has occurred.

          V.2    Remedies Not Exclusive.  (a) The remedies provided for
herein  are cumulative and are not exclusive of any other rights,
powers,  privileges  or remedies provided by  law  or  under  the
Reimbursement  Agreement,  including,  without  limitation,   all
rights  and remedies of a secured party under Article  9  of  the
Uniform Commercial Code as in effect in the State of New York  on
the  date  of  the exercise of any such remedy.  The exercise  by
CIBC  of  any  one or more remedies under Section 5.1  shall  not
constitute  a waiver of, or otherwise prohibit, the  exercise  by
CIBC  of other remedies provided herein or by law at the same  or
other times.

           (b)   CIBC  shall  not  be required  to  exercise  any
particular  rights,  powers, remedies or  benefits  hereunder  or
under  the  Reimbursement  Agreement  or  any  Related  Document.
Without limiting the generality of the foregoing, CIBC (i)  shall
be  entitled to seek to realize upon or enforce the Collateral in
such  order  as  it may from time to time determine  and  without
regard to whether or not any other collateral or security for any
of  the  Obligations shall have been resorted to, and (ii)  shall
not  be required to exhaust or enforce any particular portion  of
the  Collateral  before seeking to realize or  enforce  upon  any
other portion thereof.


                                VI

          COLLECTIONS BY THE COMPANY AND APPLICATIONS
              OF PROCEEDS IN RESPECT OF COLLATERAL

          VI.1   Collections on Pledged Bonds by the Company.  (a) If,
while any of the Obligations are outstanding, the Company becomes
entitled  to  receive or receives any payment in respect  of  any
Pledged  Bond,  the Company shall accept such payment  as  CIBC's
(and  the Banks') agent, hold it in trust on behalf of CIBC  (and
the  Banks)  and  deliver  it, with any  necessary  endorsements,
forthwith  to  CIBC  for  application  to  satisfaction  of   the
Obligations then due and payable.  All sums of money so  paid  in
respect of any payment of interest on, or any portion of purchase
price  equal  to the amount of accrued interest on,  any  Pledged
Bond which are received by the Company and paid to CIBC shall  be
credited against the obligation of the Company to pay interest as
set forth in Sections 2.5 and 2.6 of the Reimbursement Agreement.
All  sums of money so paid in respect of any payment of principal
of,  or  any  portion of purchase price equal  to  the  principal
amount of, any Pledged Bond which are received by the Company and
paid  to  CIBC  shall be credited against the obligation  of  the
Company to pay principal to CIBC as set forth in Sections 2.5 and
2.6 of the Reimbursement Agreement.

          VI.2   Application of Proceeds.  All proceeds received from the
sale  or  other disposition of, or realization on or with respect
to,  all or any part of the Collateral shall be applied by  CIBC,
in  such order as CIBC in its sole discretion (but subject to the
direction of the Majority Banks) may determine, to the payment of
the  costs and expenses of such sale, disposition or realization,
including,  without limitation, reasonable fees and  expenses  of
counsel for CIBC and the Banks and all expenses, liabilities  and
advances  of CIBC in connection therewith, and to the payment  of
the remaining Obligations (pro rata, among the Banks).

                                VII

           RELEASE OF COLLATERAL; COMPANY'S LIABILITY
                         FOR DEFICIENCY

          VII.1       Release of Collateral.  If (a) the Company makes or
causes  to  be made to CIBC a prepayment under Section 2.8(b)  of
the Reimbursement Agreement in respect of its principal repayment
obligation under Section 2.6(b) of the Reimbursement Agreement in
respect  of any Advance, (b) the Remarketing Agent causes Pledged
Bonds  at  the  time  held  hereunder  to  be  sold  or  (c)  the
Obligations are otherwise indefeasibly satisfied, upon receipt of
such  prepayment  or  of  the proceeds  of  such  sale  or  other
satisfaction  of the Obligations, Pledged Bonds in  an  aggregate
principal  amount  equal  to  the  prepayment  so  made,  or  the
principal amount of Pledged Bonds so sold, or the Obligations  so
satisfied, shall be released from the lien of this Agreement  and
the  Company  or  its  designee shall be  entitled  to  have  the
released Bonds delivered to the Company or the Remarketing  Agent
in  accordance  with Sections 13.06 and 13.07 of  the  Indenture;
provided, however, that before delivering the released  Bonds  to
the  Company or the Remarketing Agent, the Custodian  shall  have
received notice from CIBC of the reinstatement of the amounts  so
prepaid,  sold  or  satisfied as available under  the  Letter  of
Credit.

          VII.2       Company's Liability for Deficiency.  The Company
shall  in  any  event remain liable for any deficiency  remaining
unpaid after the application of the proceeds of the Collateral to
the satisfaction of the Obligations.


                                VIII

                            GENERAL

          VIII.1      Expenses.  The Company shall pay to CIBC all expenses
(including  reasonable  fees  and expenses  of  counsel)  of,  or
incident  to,  any actual or attempted sale or other  disposition
of,  or  any exchange, enforcement (whether through negotiations,
legal  proceedings  or  otherwise),  collection,  compromise   or
settlement  of or with respect to, all or any of the  Collateral,
by  litigation or otherwise.  The Company shall reimburse CIBC on
demand  for  all  reasonable  costs  and  expenses  incurred   in
connection  with  the  negotiation,  preparation,  execution  and
administration  of  this  Agreement  and  any  Amendment  hereto,
including,  without  limitation, any fees or expenses  (including
reasonable fees and expenses of counsel to the Custodian) paid by
CIBC  to  the Custodian for its services in connection with  this
Agreement.

          VIII.2      Notices.  All notices and other communications
provided for hereunder shall be in writing (including telegraphic
communication)  and mailed, telecopied, telexed,  telegraphed  or
delivered  to  the parties to the telex or telecopier  number  or
address (as the case may be) specified for the intended recipient
on  the signature page hereof, or to such other number or address
as  such recipient may have last specified by notice to the other
parties.  All such notices and communications shall, when mailed,
telecopied,  telexed or telegraphed, be effective when  deposited
in  the  mails or sent by telecopy or telex or delivered  to  the
telegraph company, respectively, addressed as aforesaid.

          VIII.3      Remedies and Waivers.  No failure or delay on the
part of CIBC in exercising any right hereunder shall operate as a
waiver  of,  or  impair, any such right.  No  single  or  partial
exercise  of any such right shall preclude any other  or  further
exercise  thereof or the exercise of any other right.  No  waiver
of any such right shall be effective unless given in writing.  No
waiver  of  any such right shall be deemed a waiver of any  other
right hereunder. The remedies herein provided are cumulative  and
not exclusive of any remedies provided by law.

          VIII.4      Amendment.  No amendment or waiver of any provision
of  this  Agreement, nor consent to any departure by the  Company
therefrom, shall in any event be effective unless the same  shall
be  in  writing  and signed by the Custodian and CIBC  (with  the
consent  of  the  Majority Banks), and then any  such  waiver  or
consent shall be effective only in the specific instance and  for
the specific purpose for which given.

          VIII.5      Assignment.  (a) This Agreement shall be binding upon
and  inure to the benefit of CIBC, the Custodian and the  Company
and  their respective successors and assigns; provided,  however,
that  the  Company and the Custodian may not assign any of  their
respective rights or obligations under this Agreement without the
prior written consent of CIBC.

           (b)  If  CIBC  or the Custodian assigns  or  otherwise
transfers  any  of  its  rights and obligations  hereunder,  each
reference in this Agreement to CIBC or the Custodian, as the case
may  be,  shall  be  deemed  to be a reference  to  CIBC  or  the
Custodian, as the case may be, and the Person or Persons to which
such rights and obligations were assigned and transferred to  the
extent of their respective interests.

          VIII.6      Governing Law.  This Agreement shall be governed by,
and construed and interpreted in accordance with, the laws of the
State of New York.

          VIII.7      Custodian Appointed Agent.  CIBC hereby appoints the
Custodian  as  its  agent  to  receive  and  hold  Pledged  Bonds
constituting  Collateral granted hereunder  for  CIBC's  account.
The  Company acknowledges such appointment and agrees  with  CIBC
and  the  Custodian,  which by its execution  of  this  Agreement
accepts  such  appointment, that, for so long as  this  Agreement
shall  remain  in  full  force and effect,  all  certificates  or
instruments representing or evidencing the Pledged Bonds (and all
other  portions of the Collateral which may be delivered  to  the
Custodian)  shall be delivered to and held by the  Custodian,  as
agent for CIBC, separate and apart from all of the other property
of  the  Custodian and subject to CIBC's exclusive direction  and
control.   Upon  receipt of any Collateral, the  Custodian  shall
promptly  give notice to CIBC specifying the Collateral received.
Upon  request  from  time to time by CIBC,  the  Custodian  shall
promptly deliver all or such portions of the Collateral  as  CIBC
shall specify and to such Persons as CIBC shall specify by notice
to the Custodian.  The Custodian shall give prompt notice to CIBC
(i) at least 30 days prior to resigning as Tender Agent under the
Indenture  and (ii) upon receipt of notice or otherwise  learning
of  (x)  its  removal as such Tender Agent or (y) any  amendment,
supplement  or  other  modification  of  the  Indenture,  or  any
consent,  waiver or release with respect thereto,  affecting  the
obligations  or  duties of the Tender Agent under  the  Indenture
with respect to the Collateral.

          VIII.8      Reasonable Care.  Subject to Section 8.7 hereof, the
Custodian  shall be deemed to have exercised reasonable  care  in
the  custody and preservation of the Collateral in its possession
if  the  Collateral is accorded treatment substantially equal  to
that which the Custodian accords its own property.  In executing,
delivering  and  performing under this  Agreement  the  Custodian
shall  be  entitled  to  all  rights, privileges  and  immunities
afforded  the  Trustee  under  the  Indenture  which  are  hereby
incorporated by reference.

          VIII.9      Integration of Terms; References in Indenture.  This
Agreement  contains  the  entire agreement  between  the  parties
relating  to  the subject matter hereof and supersedes  all  oral
statements  and  prior  writings  with  respect  thereto.    This
Agreement  shall  be  deemed  to  be  the  "Custodian  Agreement"
referenced in the Indenture.

          VIII.10     Counterparts.  This Agreement may be executed in
counterparts,  and  such  counterparts taken  together  shall  be
deemed to constitute one and the same agreement.


          VIII.11     Severability.  Any provision of this Agreement which
is  prohibited or unenforceable in any jurisdiction shall, as  to
such   jurisdiction,  be  ineffective  to  the  extent  of   such
prohibition   or   unenforceability  without   invalidating   the
remaining   provisions  hereof  or  affecting  the  validity   or

  matters  relating  to  the  Company's  participation   in   the
  transactions contemplated by this Agreement which require  said
  approval, and no other consent, approval, authorization or other
  order  of any regulatory body or administrative agency or other
  governmental  body  is  legally  required  for  the   Company's
  participation therein, except such as may have been obtained or
  may be required under the securities laws of any jurisdiction;

     (e)    The Facilities to be refinanced constitute "pollution
  control facilities" as such term is defined in the Act.

                          ARTICLE III

                         THE FACILITIES

  2.04    Facilities;  Property  of the  Company.   An  undivided
interest  in the Facilities shall be the property of the  Company
and  the Pollution Control Corporation shall have no right, title
or interest in the Facilities.

  2.05    Revision of Plans and Specifications.  The Company  may
consent  to one or more revisions to the plans and specifications
for  the  Facilities  (including without limitation  any  changes
therein,  additions thereto, substitutions therefor and deletions
therefrom),  at  any  time and from time to  time  prior  to  the
Completion Date in any respect; provided, however, that,  if  any
such  revision  shall render inaccurate the  description  of  the
Facilities  contained  in  Exhibit A hereto,  the  Company  shall
deliver to the Pollution Control Corporation and the Trustee  (a)
a revised Exhibit A containing a description of the Facilities as
revised,  the accuracy of which shall have been certified  by  an
Authorized  Company Representative, and (b) an  opinion  of  Bond
Counsel  to  the effect that the Facilities as described  in  the
revised  Exhibit A are such that the expenditure of the  proceeds
of  the  Bonds  pursuant to this Agreement will not,  in  and  of
itself,  impair the validity of the Bonds under the  Act  or  the
exclusion from gross income for federal tax purposes of  interest
on  the  Bonds.  A revision of Exhibit A hereto pursuant to  this
Section  3.02  shall  not  constitute  an  amendment,  change  or
modification of this Agreement within the meaning of Article  XII
of the Indenture.

  2.06   Maintenance of Facilities; Remodeling.  The Company shall
at  all  times exercise all of its rights, powers, elections  and
options  under the Plant Agreements to cause the Facilities,  and
every  element and unit thereof, to be maintained, preserved  and
kept in thorough repair, working order and condition and to cause
all  needful and proper repairs and renewals thereto to be  made;
provided,  however,  that the Company may  exercise  all  of  its
rights,  powers, elections and options under the Plant Agreements
to  cause the operation of the Facilities, or any element or unit
thereof,  to be discontinued if, in the judgment of the  Company,
it  is no longer advisable to operate the same, or if the Company
intends  to  sell or dispose of the same and within a  reasonable
time shall endeavor to effectuate such sale or disposition.

   After  the  Completion Date, the Company may, subject  to  the
provisions of Section 6.05 hereof, at its own expense consent  to
the  remodeling  of  the  Facilities or to  the  making  of  such
substitutions,  modifications and improvements to the  Facilities
from  time  to  time as it, in its discretion,  may  deem  to  be
desirable   for   its   uses  and  purposes,  which   remodeling,
substitutions, modifications and improvements shall  be  included
under the terms of this Agreement as part of the Facilities.

  2.07   Insurance.  The Company shall exercise all of its rights,
powers, elections and options under the Plant Agreements to  keep
the Facilities insured against fire and other risks to the extent
usually insured against by companies owning and operating similar
property,  by reputable insurance companies or, at the  Company's
election,  with  respect to all or any element  or  unit  of  the
Facilities, by means of an adequate insurance fund set aside  and
maintained  by it out of its own earnings or in conjunction  with
other  companies  through  an  insurance  fund,  trust  or  other
agreement  or,  by  means of unfunded self-insurance  as  may  be
reasonable  and  customary  by  companies  owning  and  operating
similar  property.  All proceeds of such insurance shall  be  for
the account of the Company.

  2.08   Condemnation.  The Company shall be entitled to the entire
proceeds  of any condemnation award or portion thereof  made  for
damages to or takings of the Facilities or other property of  the
Company.

  2.09   Termination of Construction.   Anything in this Agreement
to the contrary notwithstanding, the Company shall have the right
at  any time to exercise all of its rights, powers, elections and
options  under the Plant Agreements to terminate the construction
of the Facilities, in whole, if the Company shall have determined
that  the  continued construction or operation of the Facilities,
in  whole, is impracticable, uneconomical or undesirable for  any
reason.

on  the  Bonds  whether at stated maturity,  upon  redemption  or
acceleration or otherwise; provided, however, that the obligation
of  the  Company  to  make any such payment  hereunder  shall  be
reduced by the amount of any reduction under the Indenture of the
amount  of the corresponding payment required to be made  by  the
Pollution Control Corporation thereunder; and provided,  further,
that  the obligation of the Company to make any payment hereunder
shall  be deemed to be satisfied and discharged to the extent  of

understood  and  agreed  that  all  Loan  Payments  are,  by  the
Indenture, to be pledged by the Pollution Control Corporation  to

Control  Corporation hereunder (except for the Pollution  Control
Corporation's  rights under Sections 5.03, 5.04,  6.03  and  8.05
hereof  and  any  rights of the Pollution Control Corporation  to
receive  notices, certificates, requests, requisitions and  other

Security  Arrangement,  are to be pledged  and  assigned  to  the
Trustee.   The Company assents to such pledge and assignment  and
agrees  that  the  obligation of the Company  to  make  the  Loan
Payments and to make, or cause to be made, payments under Section
10.01(a)  hereof shall be absolute, irrevocable and unconditional
and  shall  not  be  subject  to  cancellation,  termination   or
abatement, or to any defense other than payment or to  any  right
of  set-off, counterclaim or recoupment arising out of any breach
by  the Pollution Control Corporation or the Trustee or any other
party under this Agreement, the Indenture or otherwise, or out of
any  obligation or liability at any time owing to the Company  by
the  Pollution  Control Corporation, the  Trustee  or  any  other
party,  and,  further,  that  the Loan  Payments  and  the  other
payments due hereunder shall continue to be payable at the  times

thereto,  or  the  use  thereof, shall have  been  taken  by  the
exercise of the power of eminent domain, and that there shall  be
no  abatement  of  or diminution in any such payments  by  reason

other reason, all of the foregoing being subject, however, to the
provisions of Sections 6.01 and 7.01 hereof.

Administration  Expenses  of the Pollution  Control  Corporation,

liable  for,  and  agrees  to indemnify and  hold  the  Pollution
Control  Corporation, the Trustee, any predecessor  Trustee,  the
Tender  Agent  and  the  Remarketing Agent and  their  directors,
officers,  employees  and  agents free  and  harmless  from,  any
liability for any loss or damage to property or any injury to  or
death  of  any person (including, without limitation,  attorneys'
and  other  agents' fees and expenses) that may be occasioned  by
any  cause whatsoever pertaining to the Facilities, except in any
case  as  a  result  of the negligence or bad  faith  or  willful
misconduct of the party otherwise to be indemnified.

   The  Company  will  indemnify and hold the  Pollution  Control
Corporation,  the  Trustee, any predecessor Trustee,  the  Tender
Agent  and the Remarketing Agent free and harmless from any loss,
claim,  damage, tax, penalty, liability, disbursement, litigation

otherwise to be indemnified.

   The  Company  will  indemnify and hold the  Pollution  Control
Corporation  and  its directors, officers, employees  and  agents
free  and  harmless from any loss, claim, damage,  tax,  penalty,

or political body upon the Facilities or any part thereof or upon
the  Pollution  Control  Corporation with  respect  to  the  Loan
Payments  or  payments pursuant to Section 10.01(a) hereof,  when
the  same  shall become due; and (b) pay or cause to be satisfied
and   discharged  or  make  adequate  provision  to  satisfy  and
discharge,  within sixty (60) days after the same  shall  accrue,
any lien or charge upon the Loan Payments or payments pursuant to
Section  10.01(a) hereof, and all lawful claims  or  demands  for
labor,  materials,  supplies or other charges which,  if  unpaid,
might  be or become a lien upon such amounts; provided, that,  if
the  Company shall first notify the Pollution Control Corporation
and  the  Trustee of its intention so to do, the Company  may  in
good  faith contest any such lien or charge or claims or  demands
in  appropriate legal proceedings, and in such event  may  permit
the  items so contested and identified as such by the Company  to
remain  undischarged and unsatisfied during the  period  of  such
contest and any appeal therefrom, unless the Trustee shall notify
the  Company  in writing that, in the opinion of counsel  to  the
Trustee  based  upon  material facts  disclosed  to  the  Trustee
without  any  duty of investigation, by nonpayment  of  any  such
items  the lien of the Indenture as to the Loan Payments will  be
materially endangered, in which event the Company shall  promptly
pay  and  cause  to be satisfied and discharged all  such  unpaid
items.   The Pollution Control Corporation shall cooperate  fully
with the Company in any such contest.


                           ARTICLE VI

                       SPECIAL COVENANTS

  2.018        Maintenance  of  Corporate Existence.   Except  as
permitted  in  this Section 6.01, the Company shall maintain  its
corporate  existence, will not dissolve or otherwise  dispose  of
all  or  substantially all of its assets and will not consolidate
with or merge with or into another corporation.  The Company  may
consolidate  with or merge into another corporation  incorporated
under the laws of the United States of America, any state thereof
or  the  District  of  Columbia, or sell, transfer  or  otherwise
dispose  of  all  or  substantially all of its  assets  (and  may
thereafter dissolve) to any Person if the surviving or  resulting
corporation (if other than the Company) or the transferee Person,
as  the case may be, prior to or simultaneously with such merger,
consolidation,  sale,  transfer  or  disposition,   assumes,   by
delivery to the Trustee and the Pollution Control Corporation  of
an instrument in writing satisfactory in form to the Trustee, all
the  obligations  of  the  Company  hereunder  including  without
limitation the obligations of the Company under Sections 5.01 and
10.01(a) hereof.  Notwithstanding the foregoing, in the  case  of
any  such  sale, transfer or other disposition by the Company  of
all  or  substantially  all of its assets,  (x)  any  such  sale,
transfer  or  other  disposition of  assets  which  includes  the
Facilities  shall be subject to the provisions  of  Section  7.01
hereof and shall not be subject to the provisions of this Section
6.01  and  (y)  in the case of any such sale, transfer  or  other
disposition of substantially all of the Company's assets but  not
including the Facilities, the transferee shall not be required to
assume  any  obligations hereunder and the Company  shall  remain
liable in respect of its obligations hereunder.

   If consolidation, merger or sale or other transfer is made  as
permitted  by  this Section 6.01, the provisions of this  Section
6.01  shall  continue  in full force and effect  and  no  further
consolidation,  merger or sale or other transfer  shall  be  made
except in compliance with the provisions of this Section 6.01.

  2.019        Permits or Licenses.  In the event that it may  be
necessary  for  the proper performance of this Agreement  on  the
part of the Company or the Pollution Control Corporation that any
application or applications for any permit or license to do or to
perform  certain  things  be made to any  governmental  or  other
agency  by the Company or the Pollution Control Corporation,  the
Company  and  the Pollution Control Corporation each shall,  upon
the request of either, execute such application or applications.

  2.020       Pollution Control Corporation's Access to Facilities.
The  Pollution  Control Corporation shall have  the  right,  upon
appropriate  prior  notice  to the Company,  to  have  reasonable
access  to  the Facilities during normal business hours  for  the
purpose of making examinations and inspections of the same.

  2.021       Tax-Exempt Status of Interest on Bonds. (a)  It  is
the  intention of the parties hereto that interest on  the  Bonds
shall be and remain tax-exempt, and to that end the covenants and
agreements  of the Pollution Control Corporation and the  Company
in this Section 6.04 and the Tax Agreement are for the benefit of
the Owners from time to time of the Bonds.

       (b)   Each  of  the  Company  and  the  Pollution  Control
Corporation  covenants and agrees for the benefit of  the  Owners
from  time  to  time of the Bonds that it will  not  directly  or
indirectly  use  or permit the use of (to the extent  within  its
control) the proceeds of any of the Bonds or any other funds,  or
take  or omit to take any action, if and to the extent such  use,
or the taking or omission to take such action, would cause any of
the  Bonds to be "arbitrage bonds" within the meaning of  Section
148  of  the Code or otherwise subject to federal income taxation
by  reason  of  Section 103 and 141 through 150 of  the  Code  or
Section 103 of the 1954 Code and Title XIII of the Tax Reform Act
of   1986,   as   applicable,  and  any  applicable   regulations
promulgated  thereunder.   To such ends,  the  Pollution  Control
Corporation and the Company will comply with all requirements  of
such  Section 148 to the extent applicable to the Bonds.  In  the
event  that at any time the Pollution Control Corporation or  the
Company  is  of  the opinion that for purposes  of  this  Section
6.04(b)  it  is necessary to restrict or limit the yield  on  the
investment of any moneys held by the Trustee under the Indenture,
the  Pollution Control Corporation or the Company shall so notify
the Trustee in writing.

      Without  limiting  the  generality of  the  foregoing,  the
Company  and the Pollution Control Corporation agree  that  there
shall  be  paid  from  time to time all amounts  required  to  be
rebated  to  the  United States of America  pursuant  to  Section
148(f) of the Code and any applicable Treasury Regulations.  This
covenant shall survive payment in full or defeasance of the Bonds
and the satisfaction and discharge of the Indenture.  The Company
specifically  covenants to pay or cause to be  paid  for  and  on
behalf  of the Pollution Control Corporation to the United States
of  America  at  the  times and in the amounts  determined  under
Section 7.08 of the Indenture the Rebate Requirement as described
in the Tax Agreement.

       (c)   The  Pollution  Control  Corporation  certifies  and
represents  that  it  has not taken, and  the  Pollution  Control
Corporation  covenants  and agrees that it  will  not  take,  any
action which results in interest paid on the Bonds being included
in  gross  income  of  the Owners of the Bonds  for  federal  tax
purposes  pursuant  to Sections 103 and 141 of  the  Code  or  to
Section 103 of the 1954 Code and Title XIII of the Tax Reform Act
of  1986, as applicable, and any regulations thereunder; and  the
Company certifies and represents that it has not taken or (to the
extent within its control) permitted to be taken, and the Company
covenants  and  agrees that it will not take or  (to  the  extent
within  its  control) permit to be taken any  action  which  will
cause  the  interest on the Bonds to become includable  in  gross
income  for federal income tax purposes; provided, however,  that
neither  the Company nor the Pollution Control Corporation  shall
be deemed to have violated these covenants if the interest on any
of  the  Bonds  becomes taxable to a person solely  because  such
person  is  a  "substantial user" of the Project  or  a  "related
person" within the meaning of Section 103(b)(13) of the 1954 Code
and  provided, further, that none of the covenants and agreements
herein  contained  shall  require  either  the  Company  or   the
Pollution Control Corporation to enter an appearance or intervene
in  any  administrative,  legislative or judicial  proceeding  in
connection  with  any  changes  in  applicable  laws,  rules   or
regulations or in connection with any decisions of any  court  or
administrative  agency or other governmental body  affecting  the
taxation  of  interest  on the Bonds.  The  Company  acknowledges
having  read Section 7.08 of the Indenture and agrees to  perform
all  duties  imposed on it by such Section 7.08, by this  Section
and  by  the  Tax  Agreement.  Insofar as  Section  7.08  of  the
Indenture    and   the   Tax   Agreement   impose   duties    and
responsibilities   on   the  Company,   they   are   specifically
incorporated herein by reference.

      (d)  Notwithstanding any provision of this Section 6.04 and
Section  7.08 of the Indenture, if the Company shall  provide  to
the  Pollution Control Corporation and the Trustee an opinion  of
Bond  Counsel  to  the effect that any specified action  required
under  this Section 6.04 and Section 7.08 of the Indenture is  no
longer  required  or  that some further or  different  action  is
required  to  maintain the tax-exempt status of interest  on  the
Bonds,  the  Company,  the  Trustee  and  the  Pollution  Control
Corporation may conclusively rely upon such opinion in  complying
with  the  requirements of this Section 6.04, and  the  covenants
hereunder shall be deemed to be modified to that extent.

  2.022        Use of Facilities.  So long as the Facilities  are
operated by or for the benefit of the Company, the Company  shall
exercise  all of its rights, powers, elections and options  under
the  Plant  Agreements to cause the Facilities  to  be  used  for
purposes contemplated by the Act.

  2.023        Financing Statements.  The Company shall file  and
record,  or  cause  to  be  filed  and  recorded,  all  financing
statements  and continuation statements referred  to  in  Section
7.07 of the Indenture.

  2.024        Security Arrangements.  (a)  In order  to  secure,
evidence or be otherwise in furtherance of the obligations of the
Company  under Section 5.01 or 10.01 hereof, or both, the Company
may,  but (except as otherwise provided in subsection (b) of this
Section 6.07) shall not be obligated to, provide, subject to  the
provisions  of subsection (g) of this Section 6.07, one  or  more
Security  Arrangements (which shall not have a stated  Expiration
Date  earlier than the earlier of (x) the date which is one  year
from  the  date of the provision of any such Security Arrangement
and  (y)  [final maturity date]) at any time, and  from  time  to
time,  and, subject to the provisions of subsections (c) and  (d)
of  this  Section 6.07, may, at any time and from time  to  time,
Terminate, or cause or allow to be terminated, any such  Security
Arrangement.   The  Company  hereby authorizes  and  directs  the
Trustee  to draw moneys under the Letter of Credit, and  to  take
actions under any other Security Arrangement, in accordance  with
the terms thereof and of the Indenture.

  (a)    Upon the initial authentication and delivery of the Bonds,
the  Company  shall  provide for the payment of  its  obligations
under  Sections  5.01  and 10.01 hereof by the  delivery  of  the
Letter of Credit.

  The Letter of Credit shall be the obligation of the Bank to pay
to  the  Trustee  or its designee, in accordance with  the  terms
thereof, such amounts as shall be specified therein and available
to be drawn thereunder for the timely payment of the principal of
and  premium, if any, and interest on the Bonds, and the purchase
price  of  Bonds,  required  to  be  made  pursuant  to,  and  in
accordance with, the provisions of the Indenture.  Drawings under
the  Letter  of  Credit  shall be made  in  accordance  with  the
provisions set forth therein and in the Indenture.

   The Company may, at its election, and with the consent of  the
Bank,  provide for one or more extensions of the Letter of Credit
in accordance with the terms of the Reimbursement Agreement.

  (b)     In  the event that the Company shall cause or  allow  a
Security  Arrangement to be Terminated, not more than sixty  (60)
days nor less than twenty (20) days prior to the Interest Payment
Date  next  preceding, or, while the Bonds  bear  interest  at  a
Flexible  Rate,  prior  to  the latest  then  scheduled  Interest
Payment  Date for any Bond, the proposed effective date  of  such
Termination:

     (i)   the  Company  shall deliver to the  Pollution  Control
  Corporation,  the  Trustee, the Tender Agent,  the  Remarketing
  Agent  and  the  Bank a notice which (A) states  the  effective
  date  of such Termination (which date shall not be earlier than
  the  first Business Day after such Interest Payment Date),  (B)
  describes any substitute Security Arrangement which  is  to  be
  provided  in  lieu thereof and (C) directs the  Trustee,  after
  taking  such actions thereunder as are required to be taken  to
  provide moneys due under the Indenture in respect of the  Bonds
  or  the  purchase  thereof, to surrender any  evidence  of  the
  Security  Arrangement to be Terminated to the  obligor  thereon
  on  the  effective date of such Termination, and  to  thereupon
  deliver  any  and  all instruments to effect  such  Termination
  which may be reasonably requested by such obligor; and

     (ii)   the  Company  shall furnish to the  Trustee  and  the
  Tender Agent an opinion of Bond Counsel to the effect that  the
  Termination of such Security Arrangement and the provision,  if
  any,  of a substitute Security Arrangement in lieu thereof  (A)
  are  authorized  under this Agreement and (B) will  not  impair
  the  validity  under the Act of the Bonds or the  exclusion  of
  interest on the Bonds from gross income for federal income  tax
  purposes.

  (c)    The Interest Payment Date next preceding the date of any
such  Termination shall not be prior to the first date  on  which
the  Bonds  are  redeemable  at  a  redemption  price  (including
premium,  if any) not exceeding the amount available to be  drawn
under  the  Security  Arrangement in respect of  such  redemption
price  pursuant  to Section 3.01(c) of the Indenture  unless  the
Company shall have furnished to the Trustee, the Tender Agent and
the  Remarketing  Agent, no later than the  fortieth  (40th)  day
preceding  such Interest Payment Date, and prior  to  taking  any
action  under such Security Arrangement to effect the Termination
thereof,  letters  or  certificates to the  effect  specified  in
Section 2.02(h)(iii) of the Indenture.

   Anything  in  this Agreement or the Indenture to the  contrary
notwithstanding, (i) if a substitute Security Arrangement  is  to
be  provided,  the substitute Security Arrangement  shall  become
effective on or before the Termination date of the then  existing
Security Arrangement and (ii) in the event that a Termination  of
a   Security  Arrangement,  or  the  Termination  of  a  Security
Arrangement and the provision of another Security Arrangement  in
lieu  thereof,  shall  require  the  Bonds  to  be  tendered  for
purchase, the Termination of such Security Arrangement shall  not
occur  until the Trustee or its duly authorized agent shall  have
made  such drawings, if any, or taken such other actions, if any,
thereunder as shall be required under the Indenture in  order  to
provide  sufficient moneys for payment of the purchase  price  of
Bonds  on  the date fixed for such mandatory tender for  purchase
and  such moneys shall have been provided to the Trustee  or  its
duly authorized agent.

  (d)       The  Company  shall, prior to the  provision  of  any
Security  Arrangement (other than the initial Letter of  Credit),
deliver  to the Trustee, the Tender Agent, the Remarketing  Agent
and  the  Bank a notice which describes any Security  Arrangement
which  is  to be provided and states the effective date  thereof,
and  shall, concurrently with the giving of such notice,  furnish
to  the Trustee an opinion of Bond Counsel to the same effect  as
the opinion described in subsection (c) of this Section 6.07.

  (e)     The  Company shall Terminate, or cause or allow  to  be
Terminated, any Security Arrangement on the first day of  a  Term
Rate Period or the Fixed Rate Period if such Security Arrangement
will  Expire prior to the first date on which the Bonds  will  be
redeemable  pursuant to Section 3.01(c) of  the  Indenture  at  a
redemption  price (including premium, if any) not  exceeding  the
amount available to be drawn under such Security Arrangement.

  (f)    The Company shall not, on or after the fortieth (40th) day
preceding  the first day of a Term Rate Period or the Fixed  Rate
Period, provide a Security Arrangement which will Expire prior to
the first date on which the Bonds will be redeemable pursuant  to
Section 3.01(c) of the Indenture at a redemption price (including
premium,  if any) not exceeding the amount available to be  drawn
under such Security Arrangement.

   SECTION  6.08   Neither the Company nor the Pollution  Control
Corporation to be Initial Purchasers of the Bonds.  In  no  event
shall  the initial purchasers of the Bonds be the Company or  any
affiliate of the Company or the Pollution Control Corporation  or
any  "insider" of either thereof within the meaning of the United
States  Bankruptcy Code, 11 U.S.C. Section 101 et seq., if  there
shall  be  in effect a security arrangement on which the  Company
shall not be the Obligor.


                          ARTICLE VII

                ASSIGNMENT, LEASING AND SELLING

  2.025       Conditions.  The Company's interest in this Agreement
may  be  assigned as a whole or in part, and its interest in  the
Facilities may be leased, sold, transferred or otherwise disposed
of by the Company as a whole or in part (whether an interest in a
specific  element  or  unit  or an undivided  interest),  to  any
Person; provided, however, that no such assignment, lease,  sale,
transfer or other disposition (a) shall relieve the Company  from
its primary liability for its obligations under Sections 5.01 and
10.01(a) hereof or (b) shall be made unless the assignee, lessee,
purchaser  or other transferee, as the case may be, prior  to  or
simultaneously  with such assignment, lease,  sale,  transfer  or
other  disposition, assumes, by delivery of an instrument to  the
Trustee   and  the  Pollution  Control  Corporation,  all   other
obligations  of  the  Company hereunder  to  the  extent  of  the
interest   assigned,  leased,  sold,  transferred  or   otherwise
disposed  of, and the Company shall be released of and discharged
from  such obligations to the extent so assumed.  Notwithstanding
the  foregoing,  (a)  if  (i)  the  Company's  interest  in  this
Agreement shall be assigned as a whole or in undivided part, (ii)
the  Company's interest in the Facilities shall be  leased  as  a
whole or in undivided part and the term of such leasehold or  the
term of any extension or extensions thereof at the option of  the
Company  shall extend beyond the maturity date of  the  Bonds  or
(iii)  the  Company's interest in the Facilities shall  be  sold,
transferred  or otherwise disposed of as a whole or in  undivided
part,  and  (b) in the event that the assignee, lessee, purchaser
or  other transferee shall assume the obligations of the  Company
under either or both of Sections 5.01 and 10.01(a) hereof for the
remaining  term  of  this  Agreement  to  the  extent   of   such
assignment,  lease,  sale,  transfer or  other  disposition,  the
Company shall be released from and discharged of all liability in
respect of such obligations to the extent so assumed (but only to
such  extent); provided, however, that if there shall  not  be  a
Security  Arrangement in effect on which the Company is  not  the
obligor,  the  release and discharge of the Company  pursuant  to
clause  (b) shall be conditioned upon delivery by the Company  to
the  Trustee  and  the Pollution Control Corporation  of  written
evidence  from  Moody's, if the Bonds are rated by  Moody's,  and
S&P,  if  the Bonds are rated by S&P, in each case to the  effect
that  such  release  and discharge of the Company,  after  giving
effect  to such assumption by the assignee, lessee, purchaser  or
other  transferee, will not, by itself, result in a reduction  or
withdrawal  of  its  ratings then in effect  on  the  Bonds;  and
provided,  further, that after any such assumption,  release  and
discharge  as  aforesaid,  the  Company  may  again  assume  such
obligations  under Section 5.01 or 10.01(a) hereof, or  both,  in
whole or in part, at any time and from time to time, and, to  the
extent  of any such assumption by the Company (but only  to  such
extent),  the  aforesaid  assignee, lessee,  purchaser  or  other
transferee shall be released from and discharged of all liability
in respect of such obligations.

   Anything  herein to the contrary notwithstanding, the  Company
shall  not make any assignment, lease or sale as provided in  the
immediately preceding paragraph unless it shall have furnished to
the  Pollution Control Corporation and the Trustee an opinion  of
Bond Counsel to the effect that the proposed assignment, lease or
sale  will not impair the validity under the Act of the Bonds  or
the  exclusion  of  interest on the Bonds from gross  income  for
federal tax purposes.

   After  any lease, sale, transfer or other disposition  of  any
element  or unit of the Facilities, or any interest therein,  the
Company  may,  at  its  option, cause such element  or  unit,  or
interest  therein,  to no longer be deemed  to  be  part  of  the
Facilities  for the purposes of this Agreement by  delivering  to
the  Pollution Control Corporation and the Trustee the agreements
or  other  documents  required pursuant to  Section  7.02  hereof
together  with  an  instrument signed by  an  Authorized  Company
Representative  stating that such element or  unit,  or  interest
therein,  shall no longer be deemed to be part of the  Facilities
for the purposes of this Agreement.

  2.026       Instrument Furnished to Trustee.  The Company shall,
within  fifteen (15) days after the delivery thereof, furnish  to
the  Pollution  Control Corporation and the Trustee  a  true  and
complete  copy of the agreements or other documents  effectuating
any such assignment, lease, sale, transfer or other disposition.

  2.027       Limitation.  This Agreement shall not be assigned nor
shall  the  Facilities be leased, sold, transferred or  otherwise
disposed  of,  in  whole or in part, except as provided  in  this
Article VII or in Section 6.01 or 5.02 hereof.


                          ARTICLE VIII

                 EVENTS OF DEFAULT AND REMEDIES

  2.028        Events  of Default.  Each of the following  events
shall  constitute  and  is referred to in this  Agreement  as  an
"Event of Default":

     (a)    a failure by the Company to make any Loan Payment or any
  payment  required under Section 10.01(a) hereof, which  failure
  shall have resulted in an "Event of Default" under clause  (a),
  (b) or (c) of Section 9.01 of the Indenture;

     (b)     a  failure by the Company to pay when due any amount
  required  to  be  paid under this Agreement or to  observe  and
  perform any covenant, condition or agreement on its part to  be
  observed or performed (other than a failure described in clause
  (a) above), which failure shall continue for a period of ninety
  (90)  days  after written notice, specifying such  failure  and
  requesting  that it be remedied, shall have been given  to  the
  Company  by  the Pollution Control Corporation or the  Trustee,
  unless the Pollution Control Corporation and the Trustee  shall
  agree  in writing to an extension of such period prior  to  its
  expiration;  provided,  however,  that  the  Pollution  Control
  Corporation and the Trustee 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

     (c)    the dissolution or liquidation of the Company, or failure
  by  the Company promptly to lift any execution, garnishment  or
  attachment of such consequence as will impair its ability to make
  any payments under this Agreement, or the entry of an order for
  relief by a court of competent jurisdiction in any proceeding for
  its  liquidation or reorganization under the provisions of  any
  bankruptcy act or under any similar act which may be  hereafter
  enacted, or an assignment by the Company for the benefit of its
  creditors,  or  the entry by the Company into an  agreement  of
  composition  with  its  creditors  (the  term  "dissolution  or
  liquidation of the Company," as used in this clause, shall not be
  construed to include the cessation of the corporate existence of
  the Company resulting either from a merger or consolidation  of
  the Company into or with another corporation or a dissolution or
  liquidation  of  the  Company following a transfer  of  all  or
  substantially all its assets as an entirety, under the conditions
  permitting such actions contained in Section 6.01 hereof).

  2.029       Force Majeure.  The provisions of Section 8.01 hereof
are subject to the following limitations: if by reason of acts of
God; strikes, lockouts or other industrial disturbances; acts  of
public  enemies;  orders of any kind of  the  government  of  the
United  States  or  of the State of Arizona, or  any  department,
agency, political subdivision, court or official of any of  them,
or   any  civil  or  military  authority;  insurrections;  riots;
epidemics; landslides; lightning; earthquakes; volcanoes;  fires;
hurricanes;   tornadoes;  storms;  floods;  washouts;   droughts;
arrests;  restraint of government and people; civil disturbances;
explosions; breakage or accident to machinery; partial or  entire
failure of utilities; or any cause or event not reasonably within
the control of the Company, the Company is unable in whole or  in
part  to  carry  out  any  one  or  more  of  its  agreements  or
obligations  contained herein, other than its  obligations  under
Sections 5.01, 5.03, 5.05, 6.01 and 10.01(a) hereof, the  Company
shall not be deemed in default by reason of not carrying out said
agreement   or  agreements  or  performing  said  obligation   or
obligations  during  the  continuance  of  such  inability.   The
Company   shall  make  reasonable  effort  to  remedy  with   all
reasonable  dispatch  the  cause or  causes  preventing  it  from
carrying  out  its agreements; provided, that the  settlement  of
strikes,  lockouts  and  other industrial disturbances  shall  be
entirely  within the discretion of the Company, and  the  Company
shall not be required to make settlement of strikes, lockouts and
other  industrial disturbances by acceding to the demands of  the
opposing party or parties when such course is in the judgment  of
the Company unfavorable to the Company.

  2.030       Remedies.  (a)  Upon the occurrence and continuance
of  any Event of Default described in clause (a) of Section  8.01
hereof,  and further upon the condition that, in accordance  with
the terms of the Indenture, the Bonds shall have been declared to
be  immediately due and payable pursuant to any provision of  the
Indenture,  the  Loan  Payments shall,  without  further  action,
become and be immediately due and payable.

   Any waiver of any "Event of Default" under the Indenture and a
rescission  and annulment of its consequences shall constitute  a
waiver of the corresponding Event or Events of Default under this
Agreement  and  a  rescission and annulment of  the  consequences
thereof.

  (a)     Upon  the  occurrence and continuance of any  Event  of
Default,  the Pollution Control Corporation, or the Trustee  with
respect  to  the  rights  of  the Pollution  Control  Corporation
assigned to the Trustee by the Indenture, may take any action  at
law  or in equity to collect any payments then due and thereafter
to  become due, or to enforce performance and observance  of  any
obligation, agreement or covenant of the Company hereunder.

  (b)     Any  amounts collected by the Trustee from the  Company
pursuant to this Section 8.03 shall be applied in accordance with
the Indenture.

  2.031        No Remedy Exclusive.  No remedy conferred upon  or
reserved  to the Pollution Control Corporation hereby is intended
to  be  exclusive of any other available remedy or remedies,  but
each  and every such remedy shall be cumulative and shall  be  in
addition  to  every  other  remedy  given  hereunder  or  now  or
hereafter existing at law or in equity or by statute.   No  delay
or  omission  to  exercise any right or power accruing  upon  any
default  shall  impair  any  such right  or  power  or  shall  be
construed to be a waiver thereof, but any such right or power may
be  exercised  from time to time and as often as  may  be  deemed
expedient.  In order to entitle the Pollution Control Corporation
to  exercise any remedy reserved to it in this Article  VIII,  it
shall not be necessary to give any notice, other than such notice
as may be herein expressly required.

  2.032       Reimbursement of Attorneys' and Agents' Fees.  If the
Company shall default under any of the provisions hereof and  the
Pollution  Control  Corporation  or  the  Trustee  shall   employ
attorneys  or agents or incur other reasonable expenses  for  the
collection  of  payments due hereunder or for the enforcement  of
performance or observance of any obligation or agreement  on  the
part  of the Company contained herein, the Company will on demand
therefor  reimburse  the  Pollution Control  Corporation  or  the
Trustee and any predecessor Trustee, as the case may be, for  the
reasonable  fees  of  such attorneys and  such  other  reasonable
expenses so incurred.

  2.033        Waiver  of  Breach.  In the event  any  obligation
created  hereby  shall be breached by either of the  parties  and
such  breach shall thereafter be waived by the other party,  such
waiver  shall be limited to the particular breach so  waived  and
shall not be deemed to waive any other breach hereunder.  In view
of   the   assignment   of  certain  of  the  Pollution   Control
Corporation's rights and interest hereunder to the  Trustee,  the
Pollution  Control Corporation shall have no power to  waive  any
breach  hereunder by the Company in respect of  such  rights  and
interest without the consent of the Trustee, and the Trustee  may
exercise  any of the rights of the Pollution Control  Corporation
hereunder.


                           ARTICLE IX

                      REDEMPTION OF BONDS

  2.034         Redemption  of  Bonds.   The  Pollution   Control
Corporation  shall  take,  or cause  to  be  taken,  the  actions
required  by the Indenture to discharge the lien created  thereby
through  the  redemption, or provision for payment or redemption,
of  all  Bonds then Outstanding, or to effect the redemption,  or
provision  for payment or redemption, of less than all the  Bonds
then   Outstanding,   upon  receipt  by  the  Pollution   Control
Corporation  and  the  Trustee  from  the  Company  of  a  notice
designating the principal amount of the Bonds to be redeemed,  or
for  the payment or redemption of which provision is to be  made,
and,  in  the case of redemption of Bonds, or provision therefor,
specifying  the date of redemption and the applicable  redemption
provision  of the Indenture.  Such redemption date shall  not  be
less  than  45 days from the date such notice is given (unless  a
shorter notice is satisfactory to the Trustee).  Unless otherwise
stated therein, such notice shall be revocable by the Company  at
any time prior to the time at which the Bonds to be redeemed,  or
for  the payment or redemption of which provision is to be  made,
are  first deemed to be paid in accordance with Article  VIII  of
the   Indenture.   The  Company  shall  furnish  any  moneys   or
Government Obligations (as defined in the Indenture) required  by
the  Indenture to be deposited with the Trustee or otherwise paid
by  the  Pollution Control Corporation in connection with any  of
the foregoing purposes.

  2.035        Compliance with the Indenture.  Anything  in  this
Agreement to the contrary notwithstanding, the Pollution  Control
Corporation  and the Company shall take all actions  required  by
this  Agreement  and the Indenture in order to  comply  with  any
provisions of the Indenture requiring the mandatory redemption of
Bonds.

  2.036        Purchase  of Bonds.  (a) In consideration  of  the
issuance  by the Pollution Control Corporation of the Bonds,  but
for  the  benefit  of the owners of the Bonds,  the  Company  has
agreed,   and  does  hereby  covenant,  to  cause  the  necessary
arrangements  to  be made and to be thereafter continued  whereby
Owners  from  time  to time of the Bonds may  deliver  Bonds  for
purchase  and  whereby  such Bonds shall  be  so  purchased.   In
furtherance  of  the  foregoing  covenant  of  the  Company,  the
Pollution  Control Corporation, at the direction of the  Company,
has  set  forth  in Section 2.02 of the Indenture the  terms  and
conditions  relating  to  the delivery of  Bonds  by  the  Owners
thereof  for  purchase,  has set forth in  Article  XIII  of  the
Indenture  the  duties and responsibilities of the  Tender  Agent
with  respect  to  the purchase of Bonds, and of the  Remarketing
Agent  with  respect to the remarketing of Bonds and has  therein
provided  for the appointment by the Company of the Tender  Agent
and  the  Remarketing Agent.  The Company hereby  authorizes  and
directs  the Tender Agent and the Remarketing Agent to  purchase,
offer,  sell and deliver Bonds in accordance with the  provisions
of Article XIII of the Indenture.

   In consideration of the Pollution Control Corporation's having
set  forth  in the Indenture the aforesaid provisions of  Section
2.02 and the Article XIII thereof, the Company covenants, for the
benefit of the owners of Outstanding Bonds, to pay, cause  to  be
paid,  to  the Tender Agent for the account of such holders  such
amounts  as  shall  be necessary to effect  the  payment  of  the
purchase  price of Outstanding Bonds delivered for purchase,  all
as  more particularly described in Sections 2.02 and 13.03 of the
Indenture; provided, however, that the obligation of the  Company
to  make any such payment hereunder to the Tender Agent shall  be
reduced  by  the amount of any moneys available for such  payment
described in clause (i), (iii) or (iv) of Section 13.03(a) of the
Indenture;  and  provided, further, that such obligation  of  the
Company  shall  be deemed to be satisfied and discharged  to  the
extent  of  the corresponding payment made by the obligor  (other
than the Company) under any Security Arrangement.

  (a)    The Pollution Control Corporation shall have no obligation
or  responsibility, financial or otherwise, with respect  to  the
purchase  of  Bonds or the making or continuation of arrangements
therefor other than as expressly set forth in subsection  (a)  of
this Section 10.01, except that the Pollution Control Corporation
shall generally cooperate with the Company, the Tender Agent  and
the  Remarketing  Agent as contemplated in Article  XIII  of  the
Indenture.

  2.037       Optional Purchase of Bonds.  The Company may at any
time,  and from time to time, furnish moneys to the Tender  Agent
accompanied  by a notice directing such moneys to be  applied  to
the  purchase  of  Bonds delivered for purchase pursuant  to  the
terms  of  the Indenture, which Bonds shall be delivered  to  the
Trustee  for cancellation in accordance with Section 13.07(b)  of
the  Indenture.   The  Company shall deliver to  the  Remarketing
Agent and the Bank a copy of any such notice.


                           ARTICLE XI

                         MISCELLANEOUS

  2.038       Term of Agreement.  This Agreement shall remain  in
full force and effect from the date hereof until the right, title
and  interest  of  the  Trustee in and to the  Trust  Estate  (as
defined  in  the  Indenture) shall have  ceased,  terminated  and
become void in accordance with Article VIII of the Indenture  and
until all payments required under this Agreement shall have  been
made.   Notwithstanding the foregoing, the covenant contained  in

  2.040       Parties in Interest.  This Agreement shall inure to

Corporation,  the  Company  and their respective  successors  and
assigns, and no other person, firm or corporation shall have  any
right,  remedy  or  claim under or by reason of  this  Agreement;
provided, however, that the lien and security interest granted to
the  Trustee  in Section 4.03 hereof, as well as the  rights  and
remedies granted to the Pollution Control Corporation in  Article
VIII hereof, shall inure to the benefit of the Trustee, on behalf
of  the  owners  from  time to time of the Bonds,  and  shall  be
enforceable  by  the Trustee as a third party beneficiary  or  as
assignee  of  the  Pollution Control Corporation;  and  provided,
further,  that  the  obligations of  the  Company  under  Section
10.01(a)  hereof shall inure to the benefit of the Tender  Agent,
on behalf of the owners from time to time of the Bonds, and shall
be  enforceable by the Tender Agent as a third party beneficiary;
and  provided,  further,  that neither the  County  of  Coconino,
Arizona nor the State of Arizona shall in any event be liable for
the  payment of the principal of or premium, if any, or  interest
on  the  Bonds  or  for the performance of any pledge,  mortgage,
obligation  or  agreement  created by  or  arising  out  of  this
Agreement or the issuance of the Bonds, and further that  neither
the  Bonds  nor any such obligation or agreement of the Pollution
Control   Corporation  shall  be  construed  to   constitute   an
indebtedness of the County of Coconino, Arizona or the  State  of
Arizona  within  the meaning of any constitutional  or  statutory
provisions  whatsoever, but shall be limited obligations  of  the
Pollution Control Corporation payable solely out of the  revenues
derived  from this Agreement or any Security Arrangement provided

or  reinvestment of any of the foregoing, as provided herein  and

  2.042       Counterparts.  This Agreement may be executed in any
number  of  counterparts, each of which,  when  so  executed  and
delivered,  shall  be  an original; but such  counterparts  shall
together constitute but one and the same Agreement.

  2.043       Severability.  If any clause, provision or section of
this  Agreement shall, for any reason, be held illegal or invalid
by  any  court,  the  illegality or invalidity  of  such  clause,
provision  or  section  shall not affect  any  of  the  remaining
clauses, provisions or sections hereof, and this Agreement  shall
be  construed and enforced as if such illegal or invalid  clause,
provision or section had not been contained herein.  In case  any
agreement or obligation contained in this Agreement be held to be
in  violation of law, then such agreement or obligation shall  be
deemed to be the agreement or obligation of the Pollution Control
Corporation  or  the Company, as the case may  be,  to  the  full
extent permitted by law.

  2.044        Governing Law.  The laws of the State  of  Arizona

II                      THE BONDS

  II.11.         Creation  of  Bonds.   There  is   hereby
authorized  and  created  under this  Indenture,  for  the
purpose  of providing moneys to pay, or redeem, or provide
for  the redemption therefor, of the 1975 Bonds, an  issue
of Bonds, entitled to the benefit, protection and security
of  this  Indenture, in the aggregate principal amount  of
Fourteen   Million   Seven   Hundred   Thousand    Dollars
($14,700,000).  Each of the Bonds shall be  designated  by
the  title  "Coconino  County, Arizona  Pollution  Control
Corporation Pollution Control Refunding Revenue Bond, 1996
Series  B  (Tucson Electric Power Company Project)".   The
Bonds  shall mature, subject to prior redemption upon  the
terms  and  conditions hereinafter set forth,  on  May  1,
2031.

  II.12.       Interest on the Bonds. The Bonds shall bear
interest,  payable on each Interest Payment Date,  at  the
lesser of (a) a Daily Rate, a Weekly Rate, a Monthly Rate,
a Flexible Rate or Rates, a Term Rate or the Fixed Rate as
selected  by  the Company in accordance with this  Section
2.02  and  (b)  12% per annum (the "Maximum  Rate").   The
Bonds  shall  initially bear interest at  a  Weekly  Rate.
When  the  Bonds bear interest at a Variable  Rate  (other
than a Term Rate) or at Flexible Rates, interest shall  be
computed on the basis of the actual number of days elapsed
over  a  year of 365 days (366 in leap years).   When  the
Bonds  bear  interest at a Term Rate or  the  Fixed  Rate,
interest shall be computed on the basis of a 360-day  year
of  twelve  30-day  months.   For  purposes  of  any  such
calculation of interest payable with respect to the  final
interest  payment  during a Term Rate  Period  immediately
followed  by  a  Flexible, Daily, Weekly or  Monthly  Rate
Period, the amount of interest which shall be payable with
respect  to such final interest period shall be determined
as  if the Interest Payment Date for such period were  the
first  day  of  the  sixth month following  the  preceding
Interest  Payment Date, notwithstanding any  extension  of
such  month  to  the first Business Day of such  month  by
reason  of the conversion to such Flexible, Daily,  Weekly
or  Monthly Rate Period.  Interest shall be paid  on  each
Bond  on  each Interest Payment Date for such  Bond.  Each
Bond shall bear interest from the Interest Payment Date to
which  interest thereon shall have been paid in full which
is,  or  immediately precedes, its date of authentication,
or, if no interest shall have been paid on the Bonds, from
the  date of initial authentication and delivery of  Bonds
under this Indenture.

    While  there exists an Event of Default, the  interest
rate   on  the  Bonds  will  be  the  rate  on  the  Bonds
immediately  prior  to the occurrence  of  such  Event  of
Default,  except that if the Bonds then bore  interest  at
Flexible  Rates  the rate during the continuance  of  such
Event of Default will be the highest Flexible Rate then in
effect  for  any  Bond.  The interest  rate  determination
method  may  be  changed by the Company  as  described  in
Sections  2.02(c)  and  2.02(d) hereof.   The  methods  of
determining the various interest rates are as provided  in
Sections  2.02(b)  and 2.02(d) hereof.  The  various  Rate
Periods  are  described  in Section  2.02(a)  and  2.02(d)
hereof.

    Notwithstanding any provision of this Indenture or  of
any  Bond, the Trustee or the Paying Agent may, but  shall
not  be  obligated  to, enter into an agreement  with  any
Owner  of 100% in aggregate principal amount of the  Bonds
providing for making any or all payments to that Owner  of
principal or redemption price of and interest on the Bonds
or  any part thereof (other than any payment of the entire
unpaid  principal  amount thereof) at a  place  and  in  a
manner other than as provided in this Indenture and in the
Bonds, without presentation or surrender of the Bonds, and
for   giving  any  notice  required  hereunder,  upon  any
conditions that shall be satisfactory to the Trustee,  the
Paying  Agent  and  the  Company; provided  that  no  such
agreement with such an Owner shall provide for less notice
than is otherwise provided for herein.

    The  Trustee or the Paying Agent, as the case may  be,
will furnish a copy of each of those agreements, certified
to  be the document executed by an officer of the Trustee,
to the Company. Any payment of principal, redemption price
or interest pursuant to such an agreement shall constitute
payment thereof pursuant to, and for all purposes of, this
Indenture.

     (a)     Rate Periods.

     (i)    Flexible Rate Periods. The Flexible Rate Period for
  each  Bond shall be of such duration, not exceeding  270
  days,  as  may be offered by the Remarketing  Agent  and
  specified by the purchaser pursuant to Section 2.02(b)(i)
  hereof, and any Bond may bear interest at a Flexible Rate,
  and have a Flexible Rate Period, different from any other
  Bond; provided that each such Flexible Rate Period shall
  (A)  commence on a Business Day (initially, the Flexible
  Rate  Conversion Date), and (B) end on a  day  which  is
  immediately followed by a Business Day.

     (ii)    Daily Rate Periods. Daily Rate Periods  shall
  commence on each Business Day and shall extend to, but not
  include, the next succeeding Business Day.

     (iii)       Weekly Rate Periods. Weekly Rate Periods shall
  commence on Wednesday of each week and end on Tuesday of
  the  following week; except that (A) in the  case  of  a
  conversion  to a Weekly Rate Period, the initial  Weekly
  Rate  Period for Bonds shall commence on the Weekly Rate
  Conversion Date and end on Tuesday of the following week;
  and  (B) in the case of a conversion from a Weekly  Rate
  Period to a different Rate Period, the last Weekly  Rate
  Period  prior  to conversion shall end on the  last  day
  immediately preceding the Conversion Date.

     (iv)   Monthly Rate Periods.   Monthly Rate Periods shall
  (A)  commence on a Monthly Rate Conversion  Date,  which
  shall be the first Business Day of a month and the first
  Business Day of each calendar month thereafter, and  (B)
  end on the last day preceding either the commencement date
  of the following Monthly Rate Period or a Conversion Date
  on  which  a different type of Rate Period shall  become
  effective.

     (v)    Term Rate Periods.  Term Rate Periods shall (A)
  commence on a Term Rate Conversion Date; and (B) end  on
  the last day preceding either the commencement date of the
  following Term Rate Period or the Conversion Date on which
  a different Rate Period shall become effective.

  (b)    Determination of Interest Rates.  The interest rate
for  the Bonds for each Rate Period (other than a Flexible
Rate Period), shall be determined by the Remarketing Agent
to  be  the lowest rate of interest which, in the judgment
of  the  Remarketing Agent as of the date of determination
and  under  prevailing market conditions, would cause  the
Bonds to have a market value equal to the principal amount
thereof,  plus accrued and unpaid interest, if  any.   The
interest rate shall be determined by the Remarketing Agent
for each Rate Period as follows:

     (i)    Flexible Rates. The Flexible Rate for each Flexible
  Rate  Period  shall be effective from and including  the
  commencement date of such period to and including the last
  day thereof. Each Flexible Rate, and Flexible Rate Period,
  shall be determined by the Remarketing Agent in connection
  with  the sale of the Bond or Bonds to which it relates.
  Each  Flexible Rate, and Flexible Rate Period, shall  be
  determined for each Bond on or prior to the first day of
  each Flexible Rate Period with respect to such Bond by the
  Remarketing Agent by the offer and acceptance of purchase
  commitments for such Bond (at a price equal to 100% of the
  principal amount) for such Flexible Rate Period and/or for
  such Flexible Rate as the Remarketing Agent deems to  be
  advisable in order to minimize the net interest cost  on
  the  Bonds under prevailing market conditions; provided,
  however,  that  the  foregoing shall  not  prohibit  the
  Remarketing Agent from accepting purchase commitments for
  longer  Flexible  Rate Periods (and at  higher  Flexible
  Rates)  than are otherwise available at the time of  any
  remarketing if the Remarketing Agent determines, in  its
  sole judgment, that, under prevailing market conditions, a
  lower net interest cost on the Bonds can be achieved over
  the  longer  Flexible  Rate Period. Notwithstanding  the
  foregoing,  no  Flexible Rate Period may be  established
  which exceeds 270 days or, if the Remarketing Agent  has
  given or received notice of any conversion to a Variable
  or Fixed Rate Period, the remaining number of days prior
  to the Conversion Date. If for any reason a Flexible Rate
  shall not be determined for any Flexible Rate Period for
  any Bond, the Flexible Rate for such Flexible Rate Period
  for such Bond shall be the Flexible Rate in effect for the
  immediately preceding Flexible Rate Period, or a Flexible
  Rate  Period shall not be determined for any  Bond,  the
  Flexible Rate Period for such Bond shall be the shortest
  period encompassing at least one Business Day.

     (ii)   Daily Rates. The Daily Rate for each Daily Rate
  Period  shall  be  effective  from  and  including   the
  commencement date thereof and shall remain in effect from
  day  to day until changed by the Remarketing Agent.  The
  initial Daily Rate and any change to the Daily Rate shall
  be determined by the Remarketing Agent between 1:00 p.m.,
  New  York  City  time, on the Business  Day  immediately
  preceding the commencement date of the Daily Rate Period
  to which it relates and 10:00 a.m., New York City time, on
  such commencement date.

     (iii)       Weekly Rates. The Weekly Rate for each Weekly
  Rate  Period  shall be effective from and including  the
  commencement  date of such period and  shall  remain  in
  effect through and including the last day thereof.  Each
  such  Weekly Rate shall be determined by the Remarketing
  Agent not later than 4:00 p.m., New York City time, on the
  Tuesday or the next Business Day immediately preceding the
  commencement date of the Weekly Rate Period to which  it
  relates.

     (iv)   Monthly Rates. The Monthly Rate for each Monthly
  Rate  Period  shall be effective from and including  the
  commencement  date of such period and  shall  remain  in
  effect  through and including the last day thereof.  The
  Monthly  Rate  for  each Monthly Rate  Period  shall  be
  determined not later than 4:00 pm., New York City time, on
  the  Business Day immediately preceding the commencement
  date of the Monthly Rate Period to which it relates.

     (v)    Term Rates. The Term Rate for each Term Rate Period
  shall  be  effective from and including the commencement
  date of such period and shall remain in effect through and
  including the last day thereof.  Each Term Rate shall be
  determined by the Remarketing Agent not later than  4:00
  p.m., New York City time, on the Business Day immediately
  preceding the commencement date of the Term Rate Period to
  which it relates.  If for any reason the duration of any
  Term  Rate Period shall not be determined for such  Term
  Rate Period, such duration shall be one year.

     (vi)   Non-Determination. If for any reason a Weekly Rate,
  Monthly Rate or Term Rate shall not be determined for  a
  Weekly  Rate  Period, Monthly Rate Period or  Term  Rate
  Period, the Weekly Rate, Monthly Rate or Term Rate, as the
  case  may be, shall be the Weekly Rate, Monthly Rate  or
  Term  Rate in effect for the immediately preceding  Rate
  Period.

  (c)     Conversions between Rate Periods. In addition to
any  conversion  to  the Fixed Rate  pursuant  to  Section
2.02(d)  hereof, at the option of the Company,  the  Bonds
may  be  converted  from the one type of  Rate  Period  to
another as follows:

     (i)    The Conversion Date for a conversion to a different
  Rate  Period shall be an Interest Payment Date on  which
  interest  is payable for the Rate Period from which  the
  conversion is to be made; provided, however, that:

       (A)    if the conversion is from Flexible Rate Periods,
     the Conversion Date shall be the last Interest Payment
     Date on which interest is payable for any Flexible Rate
     Periods theretofore established for the Bonds;

       (B)    if the conversion is from a Term Rate Period to a
     Term Rate Period of a different duration or to a different
     Rate Period, the Conversion Date may only be the last
     Interest Payment Date in respect of that Term Rate Period;
     and

       (C)    if the conversion is between Daily and Weekly Rate
     Periods,  the  Conversion Date may be any  Wednesday,
     regardless of whether the Wednesday is an Interest Payment
     Date.

     (ii)   The Company shall give written notice of any such
  conversion  to the Remarketing Agent, the  Trustee,  the
  Tender Agent and the Bank not fewer than thirty-five (35)
  days  prior to the proposed Conversion Date. Such notice
  shall specify the proposed Conversion Date and the type of
  Rate Period to which the conversion will be made, and in
  the case of conversion to a Term Rate Period, the number
  of years to be included within such Term Rate Period.

     (iii)       Not more than sixty (60) days prior to the
  Conversion Date and not fewer than thirty (30) days prior

  by  Mail  of the conversion to the Owners of  the  Bonds
  stating the proposed Conversion Date and the proposed type
  of  Rate  Period and, except in the case of  conversions
  between Daily and Weekly Rate Periods, stating that  the
  Bonds will bc subject to mandatory tender for purchase on
  the  Conversion Date at a purchase price  equal  to  the
  principal  amount thereof. The notice shall state:   (A)
  that all Bonds must be delivered to the Tender Agent for
  mandatory purchase on the Conversion Date at a  purchase
  price equal to the principal amount thereof and that  if
  the Owner fails to deliver any Bonds to the Tender Agent
  on the purchase date and the Tender Agent is in receipt of
  the purchase price therefor, such Bonds shall be deemed to
  be   purchased  on  the  purchase  date  and   ownership
  transferred  to the purchaser thereof, and (B)  that  an
  Owner  who  fails to deliver such Bonds  shall  have  no
  further rights thereunder except the right to receive the
  purchase price thereof upon presentation and surrender of
  such Bond to the Tender Agent.

     (iv)   Any conversion to a different Rate Period (except a
  conversion, if any, between Daily and Weekly Rate Periods)
  pursuant to this Section 2.02(c) shall be subject to the
  condition  that  on or before the Conversion  Date,  the
  Company  shall  have delivered to the Pollution  Control
  Corporation,  the  Trustee, the  Tender  Agent  and  the
  Remarketing Agent an opinion of Bond Counsel to the effect
  that the conversion is authorized hereunder and under the
  Act and will not, in and of itself, adversely affect the
  exclusion from gross income for federal tax purposes  of
  the interest on the Bonds.

     (v)    While the Letter of Credit shall be in effect, the
  Bonds  shall not be converted to a Term Rate  Period  or
  Flexible Rate Period unless the Letter of Credit may  be
  drawn  upon  (in respect of interest or the  portion  of
  purchase  price equal to accrued interest) in an  amount
  which  equals at least 210 days accrued interest in  the
  case of a Term Rate Period or 300 days accrued interest in
  the case of a Flexible Rate Period.

  (d)    The Fixed Rate. At the option of the Company, the
  Bonds may be converted to bear interest at a Fixed Rate to
  their final maturity. Any such conversion shall be made as
  follows:

     (i)    The Fixed Rate Conversion Date shall be an Interest
  Payment  Date on which interest is payable for the  Rate
  Period from which the conversion is to be made; provided,
  however, that (A) if the conversion is from a Term  Rate
  Period, the Fixed Rate Conversion Date shall be limited to
  an Interest Payment Date on which a new Term Rate Period
  would otherwise have commenced and (B) if the conversion
  is from a Flexible Rate Period, the Fixed Rate Conversion
  Date shall be an Interest Payment Date on which interest
  is payable for all Bonds.

     (ii)   (A)  The Company shall give written notice of any
  such conversion to the Pollution Control Corporation, the
  Trustee, the Remarketing Agent, the Tender Agent and the

  Agent shall give Notice by Mail of the conversion to the
  Owners  of all Bonds, specifying the proposed Conversion
  Date  and  stating  that the Bonds will  be  subject  to
  mandatory tender for purchase on the Conversion Date. The
  notice shall state that all Bonds must be delivered to the
  Tender Agent for mandatory purchase on the Conversion Date
  at a purchase price equal to the principal amount thereof
  and  that if the Owner fails to deliver any Bonds to the
  Tender Agent on the purchase date and the Tender Agent is
  in  receipt  of the purchase price therefor, such  Bonds
  shall be deemed to be purchased on the purchase date and
  ownership transferred to the purchaser thereof and that an
  Owner  who  fails to deliver such Bonds  shall  have  no
  further rights thereunder except the right to receive the
  purchase price thereof upon presentation and surrender of
  such Bond to the Tender Agent.

     (iii)       The Fixed Rate shall be determined by the
  Remarketing Agent no later than 3:00 pm., New York  City
  time,  on  the  Business Day preceding  the  Fixed  Rate
  Conversion Date. The Fixed Rate shall be the lowest rate
  of  interest  which, in the judgment of the  Remarketing
  Agent as of the date of determination and under prevailing
  market conditions, would cause the Bonds to have a market
  value equal to the principal amount thereof.

     (iv)   Any conversion to a Fixed Rate shall be subject to
  the condition that on or before the Fixed Rate Conversion
  Date,  the Company shall have delivered to the Pollution
  Control Corporation, the Trustee, the Tender Agent and the
  Remarketing Agent an opinion of Bond Counsel to the effect
  that the conversion is authorized hereunder and under the
  Act and will not, in and of itself, adversely affect the
  exclusion from gross income for federal tax purposes  of
  the interest on the Bonds.

  (e)     Calculation of Interest.  The Remarketing  Agent
will notify the Trustee and the Company, in writing or  by
telecopy  or telephone promptly confirmed by tested  telex
by 4:00 p.m., New York City time:

     (i)     on the last Business Day of a month in  which
  interest on the Bonds is payable at a Variable Rate other
  than Term Rate, of the Variable Rate for each day in such
  month;

     (ii)   on the first Business Day of each Flexible Rate
  Period, of the length thereof, the Flexible Rate therefor
  and the principal amount of Bonds bearing interest at such
  Flexible Rate; and

     (iii)       on the day of a determination thereof, of the
  Term Rate and the Fixed Rate.

Using the rates supplied by the Remarketing Agent pursuant
to  this  Section, the Trustee will calculate the interest
payable  on the Bonds.  The Remarketing Agent will  inform
the  Tender Agent and the Bank orally at the oral  request
of any of them of any interest rate set by the Remarketing
Agent.   The  Trustee  will  use  commercially  reasonable
efforts to respond to telephonic inquiries from Owners  of
Bonds with respect to the effective interest rate.

    The  setting  of  the  rates and  the  calculation  of
interest  payable  on  the  Bonds  as  provided  in   this
Indenture  will be conclusive and binding on  all  parties
and on each Owner of a Bond.

  (f)    Change in Rate Periods-Opinion or Opinions of Bond
Counsel.  Notwithstanding any provision  of  this  Section
2.02,  no change shall be made in the Rate Period pursuant
to  Section  2.02(c) or 2.02(d) hereof if the  opinion  or
opinions of Bond Counsel required under Section 2.02(c) or
2.02(d)  hereof  are  not  delivered  on  or  before   the
Conversion Date.  If the Tender Agent shall have sent  any
notice  to  the Owners of the Bonds regarding a change  in
the  Rate  Period,  then  in the  event  such  opinion  or
opinions  are  not  delivered,  the  Tender  Agent   shall
promptly  notify  by  commercially  reasonable  means  all
Owners  of  the  Bonds that the proposed  change  in  Rate
Period  shall not occur and that the existing Rate  Period
shall continue in effect.

  (g)    Optional Tenders for Purchase during Variable Rate
Periods.

     (i)    Owners of Bonds bearing interest at Variable Rates
  may  elect  to have their Bonds (or portions thereof  in
  amounts equal to the lowest denomination then authorized
  or whole multiples of such lowest denomination) purchased
  at a purchase price equal to 100% of the principal amount
  of  such  Bonds (or portions thereof), plus,  except  as
  hereinafter provided, accrued and unpaid interest, if any,
  on the following purchase dates and upon the giving of the
  following  telephonic  or written  notices  meeting  the
  further requirements of subsection (ii) below:

       (A)    Bonds bearing interest at Daily Rates may be

     later than 10:45 a.m., New York City time, on the purchase
     date.

       (B)    Bonds bearing interest at Weekly Rates may be

     telephonic notice, promptly confirmed in writing)  of

     York City time, on a Business Day not fewer than seven (7)
     days prior to the purchase date.

       (C)    Bonds bearing interest at Monthly Rates may be
     tendered for purchase on any Interest Payment Date for
     such Bonds at a price payable in immediately available
     funds upon delivery of a written notice of tender to the
     Tender Agent not later than 5:00 p.m., New York City time,
     on a Business Day which is not fewer than seven (7) days
     prior to the purchase date.

       (D)    Bonds bearing interest at a Term Rate may be
     tendered for purchase on the commencement date of the
     succeeding Rate Period at a price payable in immediately
     available funds upon delivery of a written notice  of

     (ii)   Each notice of tender:

       (A)    shall (y) in the case of a written notice, except
     as otherwise specified, be delivered by or on behalf of
     the Owner to the Tender Agent at its Principal Office, and
     be in form satisfactory to the Tender Agent; and (z) in
     the case of Bonds registered in the name of a nominee of
     DTC  as  DTC shall designate and held by DTC  in  its
     book-entry system, notice to the Tender Agent shall be in
     the form set forth as Exhibit D hereto.

           II.0(J)   shall  state,  whether  delivered  in
     writing  or  by  telephone  (promptly  confirmed   in
     writing)  (w)  the principal amount of  the  Bond  or
     Bonds to which the notice relates, (x) that the Owner
     irrevocably demands purchase of such Bond or Bonds or
     a specified portion thereof in an amount equal to the
     lowest  denomination  then  authorized  or  a   whole
     multiple of such lowest denomination, (y) the date on
     which such Bond or Bonds or portion thereof is to  be
     purchased, and (z) payment instructions with  respect
     to the purchase price; and

       (C)    shall automatically constitute, whether delivered
     in writing or by telephone, (w) an irrevocable offer to
     sell  the Bond or portion thereof to which the notice
     relates on the purchase date to any purchaser selected by
     the Remarketing Agent, at a price equal to the principal
     amount of such Bond or portion thereof plus, with respect
     to Bonds bearing interest at Daily Rates or Weekly Rates,
     any interest thereon accrued and unpaid as of the purchase
     date, except that Bonds held at DTC and for which  an
     optional tender has been made by delivery of the notice
     set  forth as Exhibit D hereto shall not be purchased
     unless such Bonds are transferred to the account of the
     Tender  Agent on the tender date as provided in  such
     notice, (x) an irrevocable authorization and instruction
     to the Tender Agent to effect the transfer of such Bond or
     portion thereof upon payment of such price to the Tender
     Agent  on  the  purchase  date,  (y)  an  irrevocable
     authorization and instruction to the Tender Agent  to
     effect the exchange of the Bond to be purchased in whole
     or in part for other Bonds in an equal aggregate principal
     amount  so as to facilitate the sale of such Bond  or
     portion thereof to be purchased, and (z) an acknowledgment
     that such Owner will have no further rights with respect
     to  such Bond or portion thereof upon payment of  the
     purchase price thereof to the Tender Agent on the purchase
     date, except for the right of such Owner to receive such
     purchase price upon surrender of such Bond.

           The  determination of the Tender  Agent  as  to
     whether   a  notice  of  tender  has  been   properly
     delivered   pursuant  to  the   forgoing   shall   be
     conclusive  and  binding upon the Owner.  The  Tender
     Agent  may  waive  any  conditions  to  a  conforming
     tender.

     (iii)       Not later than 11:00 a.m., New York City time,
  on  the  Business Day immediately following the date  of
  receipt of any notice of tender (or immediately upon such
  receipt, in the case of Bonds bearing interest at  Daily
  Rates),  the  Tender  Agent shall notify,  by  telephone
  promptly  confirmed in writing, in the case of a  Daily,
  Weekly or Monthly Rate, and in writing in all other cases,
  the  Trustee, the Remarketing Agent, the Company and the
  Bank  of  the  principal amount of  Bonds  (or  portions
  thereof) to be purchased and the date of purchase.

  (h)    Mandatory Tenders for Purchase.

     (i)    Each Bond bearing interest at a Flexible Rate shall
  be  subject to mandatory tender for purchase on the  day
  immediately following the last day of each Flexible Rate
  Period applicable to such Bond at a purchase price equal
  to  100%  of  the  principal amount  thereof;  provided,
  however, that any such Bond shall not be subject to such
  mandatory tender for purchase if, prior to 3:00 p.m.  on
  the  Business Day next preceding the day such  mandatory
  tender would otherwise occur hereunder, the Owner of such
  Bond  by  notice  delivered in writing or  by  telephone
  (promptly confirmed in writing) to the Remarketing Agent
  shall have elected to retain such Bond for an additional
  Flexible Rate Period and such Owner shall have agreed with
  the Remarketing Agent as to the duration of the additional
  Flexible Rate Period and the Flexible Rate to be effective
  during such period.

     (ii)   Bonds to be converted to the Fixed Rate or from one
  type  of  Rate Period to another (other than conversions
  between Daily and Weekly Rate Periods) or from any  Term
  Rate Period to a Term Rate Period of a different duration
  are  subject  to mandatory tender for purchase  on  such
  Conversion Date at a purchase price equal to 100% of the
  principal amount thereof.

     (iii)       Bonds shall be subject to mandatory tender for
  purchase  at  a purchase price that would  be  the  then
  applicable redemption price set forth in Section 3.01 (a)
  or (c) hereof if such Bonds were redeemed on such day, on
  the  first  day of the month in which the Expiration  or
  Termination of the term of any Security Arrangement shall
  occur;  provided, however, that there shall be  no  such
  mandatory  tender  if  prior to  the  giving  of  notice
  described in Section 2.10 hereof, (A) the Company  shall
  have delivered to the Tender Agent a certificate or letter
  from Moody's, if the Bonds are then rated by Moody's, and
  from  S&P,  if the Bonds are then rated by S&P,  to  the
  effect that the Termination or Expiration of such Security
  Arrangement,   or  the  Termination  of  such   Security
  Arrangement  and  the  provision  of  another   Security
  Arrangement in lieu thereof, as the case may be, will not,
  by  itself, result in a reduction or withdrawal  of  its
  ratings  then in effect on the Bonds and (B) if  another
  Security  Arrangement is to be provided in lieu thereof,
  such  substitute  Security Arrangement shall  have  been
  delivered to the Trustee and shall, by its terms, become
  effective on or before the Expiration or Termination  of
  the term of any existing Security Arrangement.

     (iv)   Bonds are subject to mandatory tender for purchase
  at a purchase price equal to 100% of the principal amount
  thereof  plus accrued interest to the date of  purchase,
  upon the occurrence of either of the following events:

           (A) receipt by the Trustee, following a drawing
     on  a Security Arrangement on which the Company shall
     not  be  the obligor to pay accrued interest, or  the
     portion  of purchase price equal to accrued interest,
     on the Bonds, of notice from the Bank that the amount
     available  to  be drawn on such Security  Arrangement
     will  not  be  reinstated (in respect of interest  or
     portion  of purchase price equal to accrued interest)
     in  the  amount of such drawing, unless  such  notice
     also  directs  the Trustee to provide notice  to  the
     Pollution  Control Corporation of its  obligation  to
     redeem  the Bonds pursuant to Section 3.01(e) hereof;
     or

           (B)  receipt by the Trustee of notice from  the
     Bank  stating  that  an Event of  Default  under  the
     Reimbursement  Agreement (or other agreement  between
     the  Company and the Bank pursuant to which the  Bank
     issued  and  delivered  to  the  Trustee  a  Security
     Arrangement)  has occurred and is continuing,  unless
     such  notice  also  directs the  Trustee  to  provide
     notice  to the Pollution Control Corporation  of  its
     obligation  to redeem the Bonds pursuant  to  Section
     3.01(e) hereof.

  Upon the occurrence of an event specified in clause  (A)
  or  (B)  of  the  immediately preceding  paragraph,  the
  Trustee  shall direct the Tender Agent to purchase,  and
  the  Tender Agent shall purchase, the Bonds on the first
  Business  Day after the receipt by the Trustee  of  such
  notice  on  which  the Trustee may  make  a  drawing  or
  drawings  on such Security Arrangement and on which  the
  proceeds   of   such  drawing  or  drawings   shall   be
  immediately available, but not prior to such date.

  II.13.       Form of Bonds.  Bonds shall be authenticated
and  delivered hereunder solely as fully registered  bonds
without  coupons  in  the  denomination  of  $100,000   or
integral  multiples thereof in the case of  Bonds  bearing
interest  at  a  Variable  Rate  other  than  Term  Rates,
$100,000 or integral multiples of $5,000 in excess thereof
in  the case of Bonds bearing interest at a Flexible  Rate
and  $5,000 or integral multiples thereof, in the case  of
bonds  bearing interest at Term Rates or the  Fixed  Rate.
Bonds  shall be numbered as determined by the Trustee  and
shall be dated the date of the initial authentication  and
delivery thereof.

    Principal  of and premium, if any, on Bonds  shall  be
payable to the Owners of such Bonds upon presentation  and
surrender  of  such Bonds at the Principal Office  of  the
Paying  Agent  or  any Co-Paying Agent.  Interest  on  the
Bonds  shall be paid by check drawn upon the Paying  Agent
and mailed to the Owners of such Bonds as of the close  of
business  on the Record Date with respect to each Interest
Payment Date at the registered addresses of such Owners as
they  shall  appear as of the close of  business  on  such
Record  Date on the registration books maintained pursuant
to Section 2.09 hereof notwithstanding the cancellation of
any  such  Bond  upon  any  exchange  or  registration  of
transfer  subsequent to such Record Date, except  that  if
and  to  the extent that there should be a default on  the
payment  of interest on any Bond, such defaulted  interest
shall  be  paid to the Owners in whose name such Bond  (or
any Bond or Bonds issued upon any exchange or registration
of  transfer  thereof) is registered as of  the  close  of
business  on  a  date  selected  by  the  Trustee  in  its
discretion, but not more than 15 days or less than 10 days
prior  to  the date of payment of such defaulted interest;
notwithstanding the foregoing, except in respect of a Term
Rate Period and the Fixed Rate Period, upon request to the
Paying  Agent  by an Owner of not less than $1,000,000  in
aggregate  principal  amount of Bonds,  interest  on  such
Bonds and, after presentation and surrender of such Bonds,
the  principal thereof shall be paid to such Owner by wire
transfer  to the account maintained within the continental
United  States specified by such Owner or, if  such  Owner
maintains  an  account with the entity  acting  as  Paying
Agent, by deposit into such account.  Payment as aforesaid
shall  be  made  in such coin or currency  of  the  United
States  of America as, at the respective times of payment,
shall  be  legal  tender  for the payment  of  public  and
private debts.

   The Bonds and the form for registration of transfer and
the form of certificate of authentication to be printed on
the Bonds are to be in substantially the forms thereof set
forth  in  Exhibits A, B and C hereto, respectively,  with
necessary   or   appropriate  variations,  omissions   and
insertions as permitted or required by this Indenture.

  II.14.        Execution of Bonds.  The  Bonds  shall  be
executed on behalf of the Pollution Control Corporation by
the President or a Vice President of the Pollution Control
Corporation   and   shall  have  affixed,   impressed   or
reproduced  thereon  the official seal  of  the  Pollution
Control  Corporation  which  shall  be  attested  by   the
Secretary  or  an  Assistant Secretary  of  the  Pollution
Control  Corporation.  Each of the foregoing officers  may
execute or cause to be executed with a facsimile signature
in  lieu  of his manual signature the Bonds, provided  the
signature  of either the President or a Vice President  of
the  Pollution  Control Corporation or  the  Secretary  or
Assistant  Secretary of the Pollution Control  Corporation
shall,   if  required  by  applicable  laws,  be  manually
subscribed.

     In   case  any  officer  of  the  Pollution   Control
Corporation  whose  signature  or  a  facsimile  of  whose
signature shall appear on the Bonds shall cease to be such
officer  before  the  authentication by  the  Trustee  and
delivery  of such Bonds, such signature or such  facsimile
shall  nevertheless  be  valid  and  sufficient  for   all
purposes,  the same as if he had remained in office  until
delivery;  and  any Bond may be signed on  behalf  of  the
Pollution Control Corporation by such persons as,  at  the
time  of  execution  of such Bond,  shall  be  the  proper
officers of the Pollution Control Corporation, even though
at  the date of such Bond or of the execution and delivery
of this Indenture any such person was not such officer.

  II.15.       Authentication of Bonds.  Only such Bonds as
shall    have   endorsed   thereon   a   certificate    of
authentication  substantially in the  form  set  forth  in
Exhibit  C  hereto duly executed by the Trustee  shall  be
entitled to any right or benefit under this Indenture.  No
Bond  shall be valid or obligatory for any purpose  unless
and  until  such certificate of authentication shall  have
been  duly  executed  by the Trustee,  and  such  executed
certificate of authentication of the Trustee upon any such
Bonds shall be conclusive evidence that such Bond has been
authenticated  and  delivered under this  Indenture.   The
Trustee's certificate of authentication on any Bond  shall
be  deemed to have been executed by it if signed  with  an
authorized signature of the Trustee, but it shall  not  be
necessary  that  the same person sign the  certificate  of
authentication on all of the Bonds issued hereunder.  This
Section 2.05 is subject to the provisions of Section 10.17
hereof.

  II.16.       Bonds Not General Obligations.  Neither the
County of Coconino, Arizona nor the State of Arizona shall
in any event be liable for the payment of the principal of
or  premium, if any, or interest on the Bonds, and neither
the  Bonds  nor  the  premium, if  any,  or  the  interest
thereon,  shall be construed to constitute an indebtedness
of  County  of Coconino, Arizona or the State  of  Arizona
within  the  meaning  of any constitutional  or  statutory
provisions whatsoever.  The Bonds and the premium, if any,
and  the interest thereon shall be limited obligations  of
the  Pollution Control Corporation payable solely from the
Receipts and Revenues of the Pollution Control Corporation
from  the  Loan  Agreement and the  other  moneys  pledged
therefor  under  this Indenture, and such  fact  shall  be
plainly  stated on the face of each Bond.   The  Pollution
Control  Corporation  shall not be obligated  to  pay  the
purchase price of Bonds from any source.

  II.17.        Prerequisites to Authentication of  Bonds.
The   Pollution  Control  Corporation  shall  execute  and
deliver  to the Trustee and the Trustee shall authenticate
the Bonds and deliver said Bonds to the initial purchasers
thereof  as  may be directed hereinafter in  this  Section
2.07.

    Upon  conversion to a Term Rate Period or to the Fixed
Rate Period, a new form of Bond may be prepared containing
a  summary  of tender and redemption provisions applicable
to  the  Bonds during such Term Rate Period or Fixed  Rate
Period.

    Prior  to  the  delivery on original issuance  by  the
Trustee of any authenticated Bonds there shall be or  have
been delivered to the Trustee:

     (a)   a duly certified copy of a resolution of the Board
  of   Directors  of  the  Pollution  Control  Corporation
  authorizing the execution and delivery of this Indenture
  and the Loan Agreement and the issuance of the Bonds;

     (b)   an original duly executed counterpart or a duly
  certified copy of the Loan Agreement;

     (c)   the Letter of Credit;

     (d)   a request and authorization to the Trustee on behalf
  of  the  Pollution Control Corporation,  signed  by  its
  President or a Vice President, to authenticate and deliver
  the Bonds in the aggregate principal amount determined by
  this  Indenture  to the purchaser or purchasers  therein
  identified  upon  payment to the Trustee,  but  for  the
  account of the Pollution Control Corporation, of  a  sum
  specified  in  such request and authorization  plus  any
  accrued  interest on such Bonds to the date of delivery;
  and

     (e)    a  written statement on behalf of the Company,
  executed  by  the President, any Vice President  or  the
  Treasurer, (i) approving the issuance and delivery of the
  Bonds and (ii) consenting to each and every provision of
  this Indenture.

  II.18.       Lost or Destroyed Bonds or Bonds Canceled in
Error.   If  any Bond, whether in temporary or  definitive
form,  is  lost (whether by reason of theft or otherwise),
destroyed (whether by mutilation, damage, in whole  or  in
part,  or  otherwise) or canceled in error, the  Pollution
Control  Corporation  may  execute  and  the  Trustee  may
authenticate a new Bond of like date and denomination  and
bearing   a   number  not  contemporaneously  outstanding;
provided that (a) in the case of any mutilated Bond,  such
mutilated  Bond shall first be surrendered to the  Trustee
and (b) in the case of any lost Bond or Bond destroyed  in
whole,  there  shall be first furnished to  the  Pollution
Control  Corporation, the Trustee and the Company evidence
of such loss or destruction.  In every case, the applicant
for  a substitute Bond shall furnish the Pollution Control
Corporation, the Trustee and the Company such security  or
indemnity as may be required by any of them.  In the event
any  lost  or destroyed Bond or a Bond canceled  in  error
shall  have  matured or is about to mature,  or  has  been
called  for  redemption, instead of issuing  a  substitute
Bond  the  Trustee may, in its discretion,  pay  the  same
without   surrender  thereof  if  there  shall  be   first
furnished  to  the  Pollution  Control  Corporation,   the
Trustee and the Company evidence of such loss, destruction
or  cancellation, together with indemnity, satisfactory to
them.   Upon  the  issuance of any  substitute  Bond,  the
Pollution Control Corporation and the Trustee may  require
the  payment of a sum sufficient to cover any tax or other
governmental  charge  that  may  be  imposed  in  relation
thereto.   The Trustee may charge the Owner  of  any  such
Bond  with  the Trustee's reasonable fees and expenses  in
connection with any transaction described in this  Section
2.08.

   Every substitute Bond issued pursuant to the provisions
of  this Section 2.08 by virtue of the fact that any  Bond
is  lost,  destroyed or canceled in error shall constitute
an  additional  contractual obligation  of  the  Pollution
Control  Corporation, whether or not  the  Bond  so  lost,
destroyed  or  canceled shall be at any time  enforceable,
and  shall  be  entitled  to  all  the  benefits  of  this
Indenture  equally and proportionately with  any  and  all
other  Bonds  duly issued hereunder.  All Bonds  shall  be
held  and  owned upon the express condition that,  to  the
extent  permitted  by  law, the foregoing  provisions  are
exclusive  with respect to the replacement or  payment  of
lost,    destroyed    or   improperly   canceled    Bonds,
notwithstanding  any  law  or  statute  now  existing   or
hereafter enacted.

  II.19.       Transfer, Registration and Exchange of Bonds.
The  Registrar  shall maintain and keep, at its  Principal
Office,  books  for the registration and  registration  of
transfer  of Bonds, which, at all reasonable times,  shall
be   open   for   inspection  by  the  Pollution   Control
Corporation,  the  Trustee  and  the  Company;  and,  upon
presentation  for  such purpose of any  Bond  entitled  to
registration or registration of transfer at the  Principal
Office  of the Registrar, the Registrar shall register  or
register   the  transfer  in  such  books,    under   such
reasonable  regulations  as the Registrar  may  prescribe.
The  Registrar  shall  make all  necessary  provisions  to
permit  the exchange or registration of transfer of  Bonds
at its Principal Office.

    The transfer of any Bond shall be registered upon  the
registration books of the Registrar at the written request
of  the  Owner thereof or his attorney duly authorized  in
writing, upon surrender thereof at the Principal Office of
the  Registrar,  together  with a  written  instrument  of
transfer  satisfactory to the Registrar duly  executed  by
the  Owner  or  his  duly authorized attorney.   Upon  the
registration  of transfer of any such Bond or  Bonds,  the
Pollution Control Corporation shall issue in the  name  of
the transferee, in authorized denominations, a new Bond or
Bonds  in  the  same  aggregate principal  amount  as  the
surrendered Bond or Bonds.

    The  Pollution Control Corporation, the  Trustee,  the
Tender  Agent, the Paying Agent, any Co-Paying Agent,  the
Registrar and the Remarketing Agent may deem and treat the
Owner  of  any  Bond as the absolute owner of  such  Bond,
whether such Bond shall be overdue or not, for the purpose
of  receiving payment of, or on account of, the  principal
of and premium, if any, and, except as provided in Section
2.03  hereof, interest on, or the purchase price of,  such
Bond and for all other purposes, and neither the Pollution
Control  Corporation, the Trustee, the Tender  Agent,  the
Paying  Agent, any Co-Paying Agent, the Registrar nor  the
Remarketing Agent shall be affected by any notice  to  the
contrary.  All such payments so made to any such Owner  or
upon his order shall be valid and effective to satisfy and
discharge  the liability upon such Bond to the  extent  of
the sum or sums so paid.

    Bonds, upon surrender thereof at the Principal  Office
of  the Registrar may, at the option of the Owner thereof,
be  exchanged for an equal aggregate principal  amount  of
Bonds of any authorized denomination.

   In all cases in which the privilege of exchanging Bonds
or  registering  the transfer of Bonds is  exercised,  the
Pollution  Control  Corporation  shall  execute  and   the
Trustee shall authenticate and deliver Bonds in accordance
with  the  provisions of this Indenture.  For  every  such
exchange  or  registration of transfer of  Bonds,  whether
temporary    or   definitive,   the   Pollution    Control
Corporation,  the  Registrar, or the Trustee  may  make  a
charge  sufficient to reimburse it for any  tax  or  other
governmental  charge required to be paid with  respect  to
such  exchange or registration of transfer, which  sum  or
sums  shall be paid by the person requesting such exchange
or  registration of transfer as a condition  precedent  to
the  exercise of the privilege of making such exchange  or
registration of transfer.  Except in connection  with  the
tender  of Bonds for purchase pursuant to their terms  and
the delivery thereof pursuant to Section 13.07 hereof, the
Registrar  shall  not be obligated (a) to  make  any  such
exchange  or registration of transfer of Bonds during  the
fifteen (15) days next preceding the date on which  notice
of  any proposed redemption of Bonds is given, (b) to make
any  exchange  or registration of transfer  of  any  Bonds
called  for redemption or (c) in the case of Bonds bearing
interest  at a Term Rate or the Fixed Rate, in the  period
following  the  Record  Date and  prior  to  the  Interest
Payment Date to which such Record Date relates.

   The Bonds are to be initially registered in the name of
Cede  &  Co., as nominee for the Depositary.   Such  Bonds
shall  not be transferable or exchangeable, nor shall  any
purported transfer be registered, except as follows:

     (a)    such  Bonds may be transferred in  whole,  and
  appropriate registration of transfer effected,  if  such
  transfer is by such nominee to the Depositary, or by the
  Depositary to another nominee thereof, or by any nominee
  of the Depositary to any other nominee thereof, or by the
  Depositary  or  any  nominee thereof  to  any  successor
  securities depositary or any nominee thereof; and

     (b)   such Bond may be exchanged for definitive Bonds
  registered  in  the respective names of  the  beneficial
  holders  thereof, and thereafter shall  be  transferable
  without restriction, if:

     (i)    the Depositary shall have notified the Company and
  the Trustee that it is unwilling or unable to continue to
  act  as securities depositary with respect to such Bonds
  and  the  Trustee  shall not have been notified  by  the
  Company  within ninety (90) days of the  identity  of  a
  successor  securities depositary with  respect  to  such
  Bonds;

     (ii)   the Company shall have delivered to the Trustee a
  written instrument to the effect that such Bonds shall be
  so exchangeable on an after a date specified therein; or

     (iii)       (1) an Event of Default shall have occurred
  and be continuing, (2) the Trustee shall have given notice
  of such Event of Default pursuant to Section 10.19 hereof
  and (3) there shall have been delivered to the Pollution
  Control  Corporation, the Company  and  the  Trustee  an
  opinion of counsel to the effect that the interests of the
  beneficial owners of such Bonds in respect thereof will be
  materially impaired unless such owners become owners  of
  definitive Bonds.

    The  Bonds delivered to the Depositary may  contain  a
legend   reflecting   the   foregoing   restrictions    on
registration of transfer and exchange.

  II.2  0.  Notice of Mandatory Tender; Special Notice  by
Tender Agent During Flexible Rate Period.  (a)  The Tender
Agent shall give notice to the Owners of the Bonds of each
event  which  requires the mandatory tender of  the  Bonds
pursuant to Section 2.02(h), other than the occurrence  of
a  last day of a Flexible  Rate Period which shall not  be
the  effective date of a new Rate Period and other than  a
mandatory   tender  for  purchase  pursuant   to   Section
2.02(h)(iv).  Such notice shall be given in the manner and
at  the  times  set forth in Section 3.03 hereof  for  the
giving  of  a  notice of redemption.   Such  notice  shall
describe the event which requires the Bonds to be tendered
and,  if such event shall be the Termination or Expiration
of   a  Security  Arrangement,  shall  also  contain   the
information referred to in Section 4.08(c) hereof.  Notice
of  a  mandatory tender for purchase pursuant  to  Section
2.02(h)(iv) shall be given by the Tender Agent as soon  as
practicable  by Mail upon receipt by the Tender  Agent  of
the   notice   from  the  Trustee  specified  in   Section
2.02(h)(iv) to all Owners of Outstanding Bonds.

  (a)     Upon  each registration of transfer  of  a  Bond
bearing  interest  at a Flexible Rate, the  Tender   Agent
shall  give written notice to the transferee that  (i)  no
notices of the length of any Flexible Rate Period  or  the
Flexible Rate borne by his Bond during such period will be
given  to the Owner of the Bond, but that such information
may  be obtained, upon request, from the Remarketing Agent
and setting forth the manner that such information may  be
obtained, (ii) the Owner of any Bond bearing interest at a
Flexible Rate will be required to tender such Bond on  its
Interest  Payment Date and (iii) no additional  notice  of
any such requirement to tender will be given to the Owner.

  II.22.        Other Obligations.  The Pollution  Control
Corporation expressly reserves the right to issue, to  the
extent  permitted by law, but shall not  be  obligated  to
issue,  obligations under another indenture or  indentures
to   provide   additional  funds  to  pay  the   cost   of
construction  of the Facilities or to refund  all  or  any
principal amount of the Bonds, or any combination thereof.

  II.23.       Temporary Bonds.  Pending the preparation of
definitive  Bonds, the Pollution Control  Corporation  may
execute  and  the Trustee shall authenticate  and  deliver
temporary  Bonds.  Temporary Bonds shall  be  issuable  as
registered   Bonds  without  coupons,  of  any  authorized
denomination,  and  substantially  in  the  form  of   the
definitive  Bonds but with such omissions, insertions  and
variations as may be appropriate for temporary Bonds,  all
as may be determined by the Pollution Control Corporation.
Temporary  Bonds  may  contain  such  reference   to   any
provisions of this Indenture as may be appropriate.  Every
temporary Bond shall be executed by the Pollution  Control
Corporation and be authenticated by the Trustee  upon  the
same conditions and in substantially the same manner,  and
with like effect, as the definitive Bonds.  As promptly as
practicable   the  Pollution  Control  Corporation   shall
execute  and shall furnish definitive Bonds and  thereupon
temporary  Bonds  may be surrendered in exchange  therefor
without charge at the Principal Office of the Trustee, and
the Trustee shall authenticate and deliver in exchange for
such temporary Bonds a like aggregate principal amount  of
definitive  Bonds of authorized denominations.   Until  so
exchanged  the  temporary Bonds shall be entitled  to  the
same benefits under this Indenture as definitive Bonds.

  II.24.       Cancellation of Bonds.  All Bonds which shall
have been surrendered to the Paying Agent or any Co-Paying
Agent for payment or redemption, and all Bonds which shall
have  been  surrendered to the Registrar for  exchange  or
registration  of  transfer,  shall  be  delivered  to  the
Trustee  for  cancellation.  All  Bonds  delivered  to  or
acquired by the Trustee for cancellation shall be canceled
and  destroyed by the Trustee.  The Trustee shall  furnish
to  the  Pollution Control Corporation, the Paying  Agent,
the Registrar and the Company counterparts of certificates
evidencing   such   cancellation   and   destruction   and
specifying such Bonds by number.

  II.25.       Payment of Principal and Interest.  For the
payment  of  interest on the Bonds, the Pollution  Control
Corporation shall cause to be deposited in the Bond  Fund,
on  each Interest Payment Date, solely out of the Receipts
and Revenues of the Pollution Control Corporation from the
Loan  Agreement  and  other moneys  pledged  therefor,  an
amount  sufficient to pay the interest to  become  due  on
such  Interest  Payment  Date.   The  obligation  of   the
Pollution Control Corporation to cause any such deposit to
be made hereunder shall be reduced by the amount of moneys
in  the Bond Fund available on such Interest Payment  Date
for the payment of interest on the Bonds.

    For  the  payment of the principal of the  Bonds  upon
maturity, the Pollution Control Corporation shall cause to
be   deposited  in  the  Bond  Fund,  on  the  stated   or
accelerated  date of maturity, solely out of the  Receipts
and Revenues of the Pollution Control Corporation from the
Loan  Agreement  and  other moneys  pledged  therefor,  an
amount sufficient to pay the principal of the Bonds.   The
obligation of the Pollution Control Corporation  to  cause
any such deposit to be made hereunder shall be reduced  by
the  amount  of moneys in the Bond Fund available  on  the
maturity  date  for the payment of the  principal  of  the
Bonds.


III                REDEMPTION OF BONDS

  III.11.      Redemption Provisions.  (a) When interest on
the  Bonds is payable at Flexible Rates or a Variable Rate
other  than  a  Term Rate, the Bonds shall be  subject  to
redemption  by the Pollution Control Corporation,  at  the
direction of the Company, in whole at any time or in  part
from  time  to time, at the principal amount thereof  plus
accrued interest to the redemption date.

  (a)     When interest on the Bonds is payable at a  Term
Rate  or  the  Fixed Rate, the Bonds shall be  subject  to
redemption  by the Pollution Control Corporation,  at  the
direction  of  the Company, in whole at any  time  at  the
principal  amount  thereof plus accrued  interest  to  the
redemption date, if:

     (i)     the  Company shall have determined  that  the
  continued  operation  of  the  Plant  is  impracticable,
  uneconomical or undesirable for any reason;

     (ii)    the  Company shall have determined  that  the
  continued  operation of the Facilities is impracticable,
  uneconomical or undesirable due to (A) the imposition of
  taxes, other than ad valorem taxes currently levied upon
  privately owned property used for the same general purpose
  as  the Facilities, or other liabilities or burdens with
  respect  to  the  Facilities or operation  thereof,  (B)
  changes in technology, in environmental standards or legal
  requirements or in the economic availability of materials,
  supplies,  equipment or labor or (C) destruction  of  or
  damage to all or part of the Facilities;

     (iii)       all or substantially all of the Facilities or
  the  Plant shall have been condemned or taken by eminent
  domain; or

     (iv)   the operation of the Facilities or the Plant shall
  have been enjoined or shall have otherwise been prohibited
  by,  or shall conflict with, any order, decree, rule  or
  regulation of any court or of any federal, state or local
  regulatory   body,  administrative   agency   or   other
  governmental body.

  (b)     When interest on the Bonds is payable at a  Term
Rate  for a Term Rate Period of five years or more or  the
Fixed  Rate,  the Bonds shall be subject to redemption  by
the Pollution Control Corporation, at the direction of the
Company,  on any day in whole at any time or in part  from
time  to  time, at the applicable redemption  price  shown
below,   in  each  case  plus  accrued  interest  to   the
redemption date, as follows:

     Anything   in   this  Indenture   to   the   contrary
notwithstanding,  in  the event  that  the  Company  shall
consolidate with, merge with or into, or sell or otherwise
transfer  all  or  substantially all  of  its  assets  to,
another corporation in accordance with Section 6.01 of the
Loan  Agreement, the Bonds shall be subject to  redemption
by  the Pollution Control Corporation, at the direction of
the Company, in whole, at any time prior to the first date
on  which  the  Bonds  are  redeemable  as  herein  before
provided  in  paragraph (c) at the redemption price  which
would be applicable on such date plus accrued interest  to
the redemption date.

  (c)    The Bonds shall be subject to mandatory redemption
by  the  Pollution Control Corporation, at  the  principal
amount  thereof  plus accrued interest to  the  redemption
date,  on  the 180th day (or such earlier date as  may  be
designated by the Company) after a final determination  by
a  court  of  competent jurisdiction or an  administrative
agency,  to  the effect that, as a result of a failure  by
the  Company to perform or observe any covenant, agreement
or  representation  contained in the Loan  Agreement,  the
interest  payable  on  the Bonds is included  for  federal
income  tax  purposes in the gross income  of  the  owners
thereof,  other  than  any  owner  of  a  Bond  who  is  a
"substantial user" of the Facilities or a "related person"
within the meaning of Section 103(b)(13) of the 1954 Code.
No  determination  by  any court or administrative  agency
shall be considered final for the purposes of this Section
3.01  (d) unless the Company shall have been given  timely
notice   of   the  proceeding  which  resulted   in   such
determination  and an opportunity to participate  in  such
proceeding, either directly or through an owner of a Bond,
and until the conclusion of any appellate review sought by
any party to such proceeding or the expiration of the time
for  seeking  such  review. The Bonds  shall  be  redeemed
either  in whole or in part in such principal amount  that
the  interest  payable on the Bonds remaining  outstanding
after  such redemption would not be included in the  gross
income of any owner thereof, other than an owner of a Bond
who  is  a  "substantial  user" of  the  Facilities  or  a
"related  person" within the meaning of Section 103(b)(13)
of the 1954 Code.

  (d)    The Bonds shall be subject to mandatory redemption
by  the  Pollution Control Corporation, at  the  principal
amount  thereof  plus accrued interest to  the  redemption
date,  upon  the  occurrence of either  of  the  following
events:

  (i)   receipt by the Trustee, following a drawing  on  a
  Security Arrangement on which the Company shall  not  be
  the  obligor to pay accrued interest, or the portion  of
  purchase price equal to accrued interest, on the  Bonds,
  of  notice from the Bank that the amount available to be
  drawn   on  such  Security  Arrangement  will   not   be
  reinstated  (in  respect  of  interest  or  portion   of
  purchase price equal to accrued interest) in the  amount
  of  such  drawing and directing the Trustee  to  provide
  notice  to  the  Pollution Control  Corporation  of  its
  resulting obligation to redeem the Bonds; or

  (ii)   receipt  by the Trustee of notice from  the  Bank
  stating   that   an   Event   of   Default   under   the
  Reimbursement Agreement (or other agreement between  the
  Company  and the Bank pursuant to which the Bank  issued
  and  delivered  to  the Trustee a Security  Arrangement)
  has   occurred  and  is  continuing  and  directing  the
  Trustee  to  provide  notice to  the  Pollution  Control
  Corporation  of its resulting obligation to  redeem  the
  Bonds.

    Upon  the occurrence of either of the events described
in  the  immediately  preceding paragraph,  the  Pollution
Control Corporation shall be obligated to redeem the Bonds
on  the  first Business Day after the occurrence  of  such
event  on which the Trustee may make a drawing or drawings
on  a Security Arrangement on which the Company shall  not
be  the  obligor and on which the proceeds of such drawing
or  drawings shall be available, but shall not redeem  the
Bonds  prior to such date.  The Trustee shall give written
notice  of  such  obligation to redeem the  Bonds  to  the
Pollution Control Corporation, the Company, the Bank,  the
Tender  Agent  and the Remarketing Agent  and  shall  give
notice thereof as soon as practicable by Mail upon receipt
by  the  Trustee of the notice specified in  Section  3.01
(e)(i) or (ii) to all Owners of Outstanding Bonds.

    The  provisions of the second preceding paragraph  are
subject  to  the condition that if either  of  the  events
described  in  clause (i) or (ii) of the second  preceding
paragraph  shall  have occurred and if the  Trustee  shall
thereafter have received notice from the Bank (a) that the
notice  which requires a mandatory redemption pursuant  to
the  second preceding paragraph has been withdrawn and (b)
that  the  amounts available to be drawn on  the  Security
Arrangement to pay (i) the principal of the Bonds  or  the
portion  of  purchase price equal to  principal  and  (ii)
interest  on  the Bonds and the portion of purchase  price
equal  to accrued interest have been reinstated, then,  in
every  such case, the event giving rise to such  mandatory
redemption   shall  be  deemed  to  be  waived   and   all
proceedings  for  such redemption shall be  rescinded  and
annulled,  and  the  Trustee shall promptly  give  written
notice  of  such waiver, rescission and annulment  to  the
Pollution Control Corporation, the Company, the Bank,  the
Tender Agent and the Remarketing Agent, and, if notice  of
such redemption shall have been given to the Owners of the
Bonds, shall give notice thereof by Mail to all Owners  of
Outstanding  Bonds;  but  no such waiver,  rescission  and
annulment  shall extend to or affect any subsequent  event
requiring  a mandatory redemption or impair any  right  or
remedy consequent thereon.

  III.12.       Selection  of Bonds  to  be  Redeemed.   A
redemption of Bonds shall be a redemption of the whole  or
of any part of the Bonds from any funds available for that
purpose.   If less than all the Bonds shall be called  for
redemption   under   any  provision  of   this   Indenture
permitting  such partial redemption, the particular  Bonds
or  portions of Bonds to be redeemed shall be selected  by
the  Trustee,  in  such  manner  as  the  Trustee  in  its
discretion  may  deem  proper, in the aggregate  principal
amount  designated  to  the  Trustee  by  the  Company  or
otherwise   as  required  by  this  Indenture;   provided,
however,  that  if,  as indicated in a certificate  of  an
Authorized   Company  Representative  delivered   to   the
Trustee,  the  Company shall have offered to purchase  all
Bonds  then Outstanding and less than all such Bonds  have
been  tendered  to  the  Company for  such  purchase,  the
Trustee,  at  the  direction  of  an  Authorized   Company
Representative, shall select for redemption all such Bonds
which  shall  not  have  been so  tendered  and  provided,
further, that, if the redemption date shall not be  during
a Flexible Rate Period, Term Rate Period or the Fixed Rate
Period, the portion of any Bond to be redeemed shall be in
the principal amount of $100,000 or some integral multiple
thereof  and that, in selecting Bonds for redemption,  the
Trustee shall treat each Bond as representing that  number
of  Bonds  which  is  obtained by dividing  the  principal
amount  of  such Bond by $100,000; and provided,  further,
that,  if  the redemption date shall be during a  Flexible
Rate  Period, a Term Rate Period or the Fixed Rate Period,
the  portion of any Bond to be redeemed shall  be  in  the
principal  amount  of  $5,000 or  some  integral  multiple
thereof (and, in the case of a Flexible Rate Period, in  a
minimum  principal  amount  of  $100,000)  and  that,   in
selecting  Bonds for redemption, the Trustee  shall  treat
each  Bond as representing that number of Bonds  which  is
obtained by dividing the principal amount of such Bond  by
$5,000. For any redemption not occurring during a Flexible
Rate Period, Term Rate Period or the Fixed Rate Period, if
it  is  determined that one or more, but not all,  of  the
$100,000 units of principal amount represented by any such
Bond is to be called for redemption, then, upon notice  of
intention to redeem such $100,000 unit or units the  Owner
of  such Bond shall forthwith surrender such Bond  to  the
Paying  Agent  or any Co-Paying Agent for (a)  payment  to
such Owner of the redemption price of the $100,000 unit or
units  of principal amount called for redemption  and  (b)
delivery  to  such Owner of a new Bond  or  Bonds  in  the
aggregate  principal amount of the unredeemed  balance  of
the  principal  amount of such Bond.  For  any  redemption
occurring  during  a  Flexible Rate Period,  a  Term  Rate
Period or the Fixed Rate Period, if it is determined  that
one or more, but not all, of the $5,000 units of principal
amount  represented by any such Bond is to be  called  for
redemption, then, upon notice of intention to redeem  such
$5,000  unit  or  units,  the Owner  of  such  Bond  shall
forthwith surrender such Bond to the Paying Agent  or  any
Co-Paying  Agent  for (y) payment to  such  Owner  of  the
redemption  price  (including the redemption  premium,  if
any,   and   accrued  interest  to  the  date  fixed   for
redemption)  of  the  $5,000 unit or  units  of  principal
amount  called  for redemption and (z)  delivery  to  such
Owner  of  a new Bond or Bonds in the aggregate  principal
amount  of the unredeemed balance of the principal  amount
of  any  such  Bond.   Bonds representing  the  unredeemed
balance of the principal amount of any such Bond shall  be
delivered  to the Owner thereof, without charge  therefor.
In  selecting Bonds for redemption, (i) the Trustee  shall
first  select Bonds tendered for purchase pursuant to  the
terms   thereof   and  delivered,  and   then   held,   as
contemplated  in  Section 13.07(c)  hereof  and  (ii)  the
Trustee   may  treat  Bonds  so  tendered  and   otherwise
delivered  pursuant  to Section 13.07  hereof  during  the
fifteen  (15)  days next preceding the  first  mailing  of
notice of any proposed redemption of Bonds as though  such
tender  and delivery had not occurred.  If a Bond selected
for  redemption shall have been tendered pursuant  to  the
terms  thereof  and delivered pursuant  to  Section  13.07
hereof on or after the fifteenth (15th) day next preceding
the first mailing of notice of any proposed redemption  of
Bonds,  then  the  Bond so delivered pursuant  to  Section
13.07  hereof shall be deemed to be the Bond  so  tendered
and  selected for redemption.  If the Owner  of  any  such
Bond  of  a  denomination greater  than  $100,000  ($5,000
during a Term Rate Period or the Fixed Rate Period)  shall
fail  to  present  such Bond to the Paying  Agent  or  any
Co-Paying  Agent  for payment and exchange  as  aforesaid,
such  Bond shall, nevertheless, become due and payable  on
the  date  fixed  for  redemption to  the  extent  of  the
$100,000  ($5,000 during a Term Rate Period or  the  Fixed
Rate Period) unit or units of principal amount called  for
redemption (and to that extent only).

  III.13.      Procedure for Redemption.  (a) In the event
any  of  the Bonds are called for redemption, the  Trustee
shall  give  notice, in the name of the Pollution  Control
Corporation, of the redemption of such Bonds, which notice
shall (i) specify the Bonds to be redeemed, the redemption
date,  the redemption price, and the place or places where
amounts  due  upon such redemption will be payable  (which
shall  be the Principal Office of the Paying Agent or  any
Co-Paying Agent) and, if less than all of the Bonds are to
be  redeemed, the numbers of the Bonds to be redeemed, and
the  portion  of the principal amount of any  Bond  to  be
redeemed  in  part,  (ii)  state  any  condition  to  such
redemption  and  (iii) state that on the redemption  date,
and upon the satisfaction of any such condition, the Bonds
or  portions  thereof to be redeemed shall cease  to  bear
interest.   Such  notice  may  set  forth  any  additional
information  relating  to  such redemption.   Such  notice
shall  be  given by Mail at least thirty (30)  days  prior
(except  in  the case of a redemption pursuant to  Section
3.01(e)) to the date fixed for redemption to the Owners of
the  Bonds to be redeemed; provided, however, that failure
duly  to  give such Notice by Mail, or any defect therein,
shall  not affect the validity of any proceedings for  the
redemption of Bonds as to which there shall have  been  no
such  failure  or defect; and provided, further,  that  if
such Notice by Mail shall not have been given with respect
to a Bond delivered pursuant to Section 13.07 hereof on or
after  the  fifteenth (15th) day next preceding the  first
mailing of notice of any proposed redemption of Bonds, and
if  such  Bond  shall be deemed to have been selected  for
redemption  pursuant to Section 3.02 hereof,  such  notice
shall  be  attached  to such Bond prior  to  the  delivery
thereof pursuant to Section 13.07 hereof.  If a notice  of
redemption shall be unconditional, or if the conditions of
a   conditional  notice  or  redemption  shall  have  been
satisfied, then upon presentation and surrender  of  Bonds
so  called  for  redemption at  the  place  or  places  of
payment, such Bonds shall be redeemed.  The Trustee  shall
promptly  deliver to the Company and the Bank  a  copy  of
each such notice of redemption.

  (a)     With  respect to any notice of  an  event  which
requires the Owners of the Bonds to tender their Bonds  in
accordance  with Section 2.02(h)(iii) hereof, such  notice
shall  contain  the  information referred  to  in  Section
4.08(c) hereof.

  (b)   With respect to any notice of redemption of Bonds in
accordance with subsection (a), (b) or (c) of Section 3.01
hereof, unless, upon the giving of such notice, such Bonds
shall  be  deemed to have been paid within the meaning  of
Article  VIII  hereof, such notice shall state  that  such
redemption shall be conditional upon the receipt,  by  the
Trustee at or prior to the opening of business on the date
fixed for such redemption, of moneys sufficient to pay the
principal  of  and premium, if any, and interest  on  such
Bonds  to  be redeemed, and that if such moneys shall  not
have been so received said notice shall be of no force and
effect and the Pollution Control Corporation shall not  be
required  to  redeem such Bonds.  In the event  that  such
notice  of redemption contains such a condition  and  such
moneys  are not so received, the redemption shall  not  be
made  and  the  Trustee  shall within  a  reasonable  time
thereafter give notice, in the manner in which the  notice
of  redemption  was given, that such moneys  were  not  so
received.

  (c)     Any Bonds and portions of Bonds which have  been
duly  selected for redemption and which are deemed  to  be
paid in accordance with Article VIII hereof shall cease to
bear interest on the specified redemption date.

  (d)    The Trustee shall not give any notice of redemption
to  be made in accordance with Section 3.01(c) hereof when
a  Security  Arrangement shall be in effect on  which  the
Company  shall  not be the obligor unless,  prior  to  the
giving   of   such  notice,  either  (i)   such   Security
Arrangement shall expressly allow a drawing thereunder for
the purpose of paying, and in an amount sufficient to pay,
any  redemption  premium payable upon such redemption,  or
(ii) there shall be on deposit in the Bond Fund moneys  in
an  amount  sufficient to pay such premium and  which  are
Available Moneys.

  III.14.        No  Partial  Redemption  After   Default.
Anything    in    this   Indenture   to    the    contrary
notwithstanding,  if  there shall  have  occurred  and  be
continuing an Event of Default defined in clause (a),  (b)
or  (c)  of  the first paragraph of Section  9.01  hereof,
there shall be no redemption of less than all of the Bonds
at the time Outstanding.

  III.15.       Payment  of  Redemption  Price.   For  the
redemption  of  any  of the Bonds, the  Pollution  Control
Corporation shall cause to be deposited in the Bond  Fund,
on  the  redemption date, solely out of the  Receipts  and
Revenues  of  the Pollution Control Corporation  from  the
Loan  Agreement, an amount sufficient to pay the principal
of and premium, if any, and interest to become due on such
redemption date.  The obligation of the Pollution  Control
Corporation to cause any such deposit to be made hereunder
shall be reduced by the amount of moneys in the Bond  Fund
available  on  such  redemption date for  payment  of  the
principal of and premium, if any, and accrued interest  on
the Bonds to be redeemed.


IV                    THE BOND FUND

otherwise provided in subsection (c) of this Section  4.04
and in Sections 4.06, 9.01 and 10.04 hereof, moneys in the

General Account.

  (c)    Upon  receipt by the Trustee from the Bank  of  a

amount equal to the lesser of (i) the total amount owed by
the  Company  to  the Bank in respect of such  drawing  or
drawings  as specified in such notice and (ii)  the  total
amount  on deposit in all accounts and subaccounts  within
the Bond Fund; provided, however, that there shall not  be

directions  that  the  same are  to  be  maintained  in  a
segregated  account or subaccount until  the  same  became
Available  Moneys or (z) proceeds from the investment  and
reinvestment  of  moneys described in clause  (x)  or  (y)
above.

  IV.15.       Custody of Bond Fund; Withdrawal of Moneys.
The  Bond Fund shall be in the custody of the Trustee  but
in  the name of the Pollution Control Corporation and  the
Pollution   Control  Corporation  hereby  authorizes   and
directs  the  Trustee to withdraw from the Bond  Fund  and
furnish to the Paying Agent funds constituting part of the
Trust  Estate  sufficient  to pay  the  principal  of  and
premium,  if  any, and interest on the Bonds as  the  same
shall  become  due and payable, and to withdraw  from  the
Bond  Fund  funds  sufficient to  pay  any  other  amounts
payable  therefrom  as  the  same  shall  become  due  and
payable.

  IV.16.        Bonds Not Presented for Payment.   In  the
event  any  Bonds shall not be presented for payment  when
the  principal thereof and premium, if any, thereon become
due,  either  at  maturity  or  at  the  date  fixed   for
redemption  thereof or otherwise, if moneys sufficient  to
pay  such  Bonds  are  held by the  Paying  Agent  or  any
Co-Paying Agent for the benefit of the Owners thereof, the
Paying  Agent  shall  segregate and hold  such  moneys  in
trust,  without  liability for interest thereon,  for  the
benefit  of  holders of such Bonds, who shall,  except  as
provided   in  the  following  paragraph,  thereafter   be
restricted  exclusively to such  fund  or  funds  for  the
satisfaction of any claim of whatever nature on their part
under this Indenture or relating to said Bonds.

    Any moneys which the Paying Agent shall segregate  and
hold  in  trust  for the payment of the principal  of  and
premium,  if  any, or interest on any Bond  and  remaining
unclaimed  for one year after such principal, premium,  if
any,  or  interest has become due and payable shall,  upon
the Company's written request to the Paying Agent, be paid
to the Company, with notice to the Trustee of such action;
provided,  however,  that, if a  Security  Arrangement  on
which  the  Company shall not be an obligor is in  effect,
prior to any such payment to the Company as aforesaid, the
Paying Agent shall deliver to the Bank a notice specifying
the  date  of such payment (which date shall not  be  less
than four (4) Business Days after the date of delivery  of
such notice), and if prior to such specified date the Bank
shall  have delivered to the Paying Agent a notice stating
that amounts are owed by the Company to the Bank under the
Reimbursement  Agreement  and  have  not  been  paid,  the
Trustee,  prior  to  any such payment to  the  Company  as
aforesaid,  shall pay to the Bank an amount equal  to  the
lesser of (a) the total amount owed by the Company to  the
Bank  as specified in such notice and (b) the total amount
of  such  unclaimed  moneys; and provided,  further,  that
before the Paying Agent shall be required to make any such
repayment, the Paying Agent may, and at the request of the
Trustee shall, at the expense of the Company cause  notice
to  be  given once by Publication to the effect 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 notice by Publication, any unclaimed
balance of such moneys then remaining will be paid to  the
Company.   After the payment of such unclaimed  moneys  to
the  Company, the Owner of such Bond shall thereafter look
only  to  the  Company for the payment  thereof,  and  all
liability of the Trustee and the Paying Agent with respect
to such moneys shall thereupon cease.

  IV.17.        Moneys  Held  in Trust.   All  moneys  and
Investment  Securities held by the  Trustee  in  the  Bond
Fund, and all moneys required to be deposited with or paid
to  the  Trustee for deposit into the Bond Fund,  and  all
moneys  withdrawn  from the Bond  Fund  and  held  by  the
Trustee,  the  Paying Agent, any Co-Paying Agent,  or  the
Tender  Agent,  shall be held by the Trustee,  the  Paying
Agent,  any  Co-Paying Agent or the Tender Agent,  as  the
case  may  be,  in trust, and such moneys  and  Investment
Securities  (other  than moneys held pursuant  to  Section
4.06  hereof and moneys or Investment Securities  held  in
any  subaccount  within  the  Bond  Fund  established   in
furtherance of the obligations of the Company under clause
(b)  of Section 6.04 of the Loan Agreement), while so held
or  so  required to be deposited or paid, shall constitute
part  of  the Trust Estate and be subject to the lien  and
security  interest created hereby in favor of the Trustee,
first, for the benefit of the Owners from time to time  of
the  Bonds and, second, for the benefit of the Bank as and
to  the extent provided herein.  The Company shall have no
right,  title  or interest in the Bond Fund,  except  such
rights as may arise after the right, title and interest of
the  Trustee in and to the Trust Estate and all covenants,
agreements and other obligations of the Pollution  Control
Corporation  under  this  Indenture  shall  have   ceased,
terminated  and become void and shall have been  satisfied
and discharged in accordance with Article VIII hereof.

  IV.18.        Security Arrangements.  (a) The Letter  of
Credit  shall be the obligation of the Bank to pay to  the
Trustee,  in  accordance  with  the  terms  thereof,  such
amounts as shall be specified therein and available to  be
drawn  thereunder for the timely payment of the  principal
of and premium, if any, and interest on the Bonds, and the
purchase price of Bonds, required to be made pursuant  to,
and  in accordance with, the provisions of this Indenture.
Drawings  under  the Letter of Credit for the  payment  of
principal  of,  and premium, if any, and interest  on  the
Bonds  shall be made only to the extent moneys from  other
eligible sources specified in Section 4.04(a) hereof shall
not  be  available for such payment.  The Letter of Credit
shall  be reduced to the extent of any drawings thereunder
and reinstated in accordance with the terms thereof.

    The  Trustee  shall draw moneys under  the  Letter  of
Credit   and   take  action  under  any   other   Security
Arrangement  in accordance with the terms thereof  to  the
extent  necessary to make timely payments of principal  of
and premium, if any, and interest on the Bonds required to
be  made  from  the  Bond Fund; provided,  however,  that,
anything  herein  to the contrary notwithstanding,  in  no
event  shall  the Trustee draw moneys under  any  Security
Arrangement  on  which the Company is not the  obligor  in
order to make payments of principal of or premium, if any,
or  interest on Bonds or the purchase price of Bonds  held
of  record by the Company or by the Tender Agent  for  the
account of the Company pursuant to Section 13.07(d) hereof
if  the  Security Arrangement prohibits  by  its  terms  a
drawing  thereunder for such purpose.  Upon any  reduction
in  the  aggregate principal amount of Bonds  Outstanding,
the  Trustee  shall,  at the direction  of  an  Authorized
Company Representative, request the Bank to make permanent
correlative  reductions in the amounts that may  be  drawn
under  the Letter of Credit or take corresponding  actions
with  respect  to  any  other Security  Arrangement.   For
extensions  of  the term of the Letter of  Credit  or  any
Security  Arrangement, the Trustee shall, at the direction
of an Authorized Company Representative, take such actions
as  are required to effect such extension of the Letter of
Credit,  surrender the Letter of Credit  to  the  Bank  in
exchange for a letter of credit of the Bank conforming  in
all  material respects to the Letter of Credit except that
the   Expiration   date  shall  be   extended   and   take
corresponding  actions with respect to any other  Security
Arrangement.  If at any time there shall cease to  be  any
Bonds  Outstanding hereunder, the Trustee  shall  promptly
surrender  the Letter of Credit to the Bank, in accordance
with  the  terms of the Letter of Credit, for cancellation
or  shall take corresponding actions with respect  to  any
other Security Arrangement.

  (a)   If at any time there shall have been delivered  to
the  Trustee,  all as described in and in accordance  with
the  applicable  provisions of Section 6.07  of  the  Loan
Agreement, (i) a notice of the Company, (ii) the  required
opinion  of  Bond  Counsel, if  any,  (iii)  the  required
certificates or letters of Moody's and S&P,  if  any,  and
(iv)  the Security Arrangement, if any, described in  such
notice,  then  the  Trustee shall accept  such  substitute
Security   Arrangement,  if  any,  and  comply  with   the
direction  of  the  Company, if  any,  contained  in  such
notice.

  (b)    The Trustee shall give notice, in the name of the
Pollution   Control  Corporation,  of  any  amendment   or
Termination or Expiration of any Security Arrangement  and
of  the  provision of any substitute Security Arrangement,
which  notice  shall (i) describe generally  the  Security
Arrangement,  if  any, in effect prior to  any  amendment,
Termination,  Expiration  or provision  and  the  Security
Arrangement,  if any, in effect or to be  in  effect  upon
such  amendment, Termination, Expiration or provision  and
(ii)  state  the  date  of  such  amendment,  Termination,
Expiration  or provision.  Such notice shall be  given  by
Mail to all Owners of Bonds promptly after such amendment,
Termination, Expiration or provision, except that if, as a
result  of such amendment, Termination or Expiration,  the
Bonds shall be required to be tendered for purchase,  such
notice may be given together with the notice thereof given
by  the  Tender Agent pursuant to Section 2.10 hereof  and
shall,  if  such information is furnished by the  Company,
state  the  Rating Category or Categories  (including  any
refinements or gradations thereof), if any, in  which  the
Bonds  are  expected  to  be  rated  by  Moody's  and  S&P
subsequent to such amendment, Termination or Expiration of
a Security Arrangement and the provision of any substitute
Security Arrangement.

  (c)   Anything in this Indenture or the Loan Agreement to
the   contrary  notwithstanding,  in  the  event  that   a
Termination  of a Security Arrangement, or the Termination
of  a  Security Arrangement and the provision  of  another
Security  Arrangement in lieu thereof, shall  require  the
Owners  of  Bonds to tender their Bonds for  purchase  the
Trustee  shall not surrender any evidence of the  Security
Arrangement to be Terminated until the Trustee shall  have
made  such drawings, if any, or taken such other  actions,
if  any,  thereunder  as  shall  be  required  under  this
Indenture  in order to provide sufficient moneys  for  the
related purchase of Bonds and such moneys shall have  been
provided to the Trustee.


V                DISPOSITION OF PROCEEDS

  V.11.        Disposition of Proceeds.  The proceeds from
the  issuance  and sale of the Bonds shall be  applied  as
provided in Section 4.03 of the Loan Agreement.


VI                     INVESTMENTS

  VI.11.        Investments.  The moneys in the Bond  Fund
shall,  at  the direction of the Company, be invested  and
reinvested  in  Investment Securities; provided,  however,
that  moneys  constituting proceeds  of  a  drawing  on  a
Security  Arrangement  on which the  Company  is  not  the
obligor  and,  while a Security Arrangement on  which  the
Company  is not the obligor is in effect, any moneys  held
by the Paying Agent pursuant to Section 4.06 hereof, or by
the  Tender  Agent  pursuant to Section  13.03(c)  hereof,
shall  be  invested  only  in  Government  Obligations  as
described  in  clause (a) of the definition thereof  which
shall  not  contain provisions permitting  the  redemption
thereof  at  the  option of the issuer and  which  have  a
remaining  term to maturity not exceeding 30 days  and  in
any  event  maturing as needed.  Any Investment Securities
may  be  purchased subject to options or other  rights  in
third  parties to acquire the same.  In addition,  subject
to  the  proviso contained in the first sentence  of  this
Section  6.01 and except for moneys in the General Account
of  the Bond Fund, the Trustee shall, at the direction  of
the Company, enter into (i) reverse repurchase agreements,
option  agreements and agreements to lend securities  with
respect  to any Investment Securities held by it and  (ii)
transactions for the purchase or sale of financial futures
contracts   in  obligations  which  constitute  Investment
Securities  or options on financial futures  contracts  in
obligations   which   constitute  Investment   Securities.
Subject  to  the further provisions of this Section  6.01,
such  investments shall be made by the Trustee as directed
and  designated  by  the Company in a certificate  of,  or
telephonic advice promptly confirmed by a certificate  of,
an  Authorized Company Representative.  As  and  when  any
amounts thus invested may be needed for disbursements from
the  Bond  Fund, the Trustee shall request the Company  to
designate   such  investments  to  be  sold  or  otherwise
converted  into  cash to the credit of the  Bond  Fund  as
shall be sufficient to meet such disbursement requirements
and shall then follow any directions in respect thereto of
an Authorized Company Representative.  As long as no Event
of  Default (as defined in Section 9.01 hereof) shall have
occurred  and  be continuing, the Company shall  have  the
right  to  designate the investments to  be  sold  and  to
otherwise direct the Trustee in the sale or conversion  to
cash  of the investments made with the moneys in the  Bond
Fund,  provided  that  the Trustee shall  be  entitled  to
conclusively  assume  the absence of  any  such  Event  of
Default unless it has notice thereof within the meaning of
Section  10.05  hereof.  At any time that S&P  or  Moody's
rates the Bonds, the General Account of the Bond Fund  may
only  be  invested in Investment Securities with a  rating
level at least as high as the current rating of the Bonds.


VII                 GENERAL COVENANTS

  VII.11.       No  General Obligations.  Each  and  every
covenant herein made, including all covenants made in  the
various  sections of this Article VII, is predicated  upon
the condition that neither the County of Coconino, Arizona
nor  the State of Arizona shall in any event be liable for
the  payment of the principal of, or premium, if  any,  or
interest on the Bonds or for the purchase of Bonds or  for
the  performance  of any pledge, mortgage,  obligation  or
agreement  created by or arising out of this Indenture  or
the  issuance of the Bonds, and further that  neither  the
Bonds,  nor the premium, if any, or interest thereon,  nor
any  such obligation or agreement of the Pollution Control
Corporation   shall   be  construed   to   constitute   an
indebtedness  of the County of Coconino,  Arizona  or  the
State  of Arizona within the meaning of any constitutional
or  statutory  provisions whatsoever.  The Bonds  and  the
interest  and  premium, if any, thereon shall  be  limited
obligations  of the Pollution Control Corporation  payable
solely  from  the Receipts and Revenues of  the  Pollution
Control Corporation from the Loan Agreement and the  other
moneys pledged therefor.

    The Pollution Control Corporation shall promptly cause
to  be  paid,  solely from the sources stated herein,  the
principal  of and premium, if any, and interest  on  every
Bond  issued  under this Indenture at the  place,  on  the
dates  and in the manner provided herein and in said Bonds
according  to  the true intent and meaning  thereof.   The
Pollution Control Corporation shall have no obligation  or
responsibility with respect to the purchase  of  Bonds  or
the  making  or  continuation  of  arrangements  therefor,
except  that  the  Pollution  Control  Corporation   shall
generally cooperate with the Company, the Tender Agent and
the  Remarketing  Agent as contemplated  in  Article  XIII
hereof.

  VII.12.       Performance of Covenants of the  Pollution
Control   Corporation;  Representations.   The   Pollution
Control Corporation shall faithfully perform at all  times
any  and  all  covenants, undertakings,  stipulations  and
provisions contained in this Indenture, in any  and  every
Bond executed, authenticated and delivered hereunder,  and
in  all  proceedings  pertaining thereto.   The  Pollution
Control  Corporation represents that it is duly authorized
under the Constitution and laws of the State of Arizona to
issue the Bonds authorized hereby, to enter into the  Loan
Agreement and this Indenture, and to pledge and assign  to
the  Trustee the Trust Estate, and that the Bonds  in  the
hands  of  the  Owners thereof are and will be  valid  and
binding  limited  obligations  of  the  Pollution  Control
Corporation.

  VII.13.      Maintenance of Rights and Powers; Compliance
with Laws.  The Pollution Control Corporation shall at all
times  use  its  best  efforts to maintain  its  corporate
existence  or  assure the assumption  of  its  obligations
under this Indenture by any public body succeeding to  its
powers  under the Act; and it shall at all times  use  its
best  efforts  to  comply  with  all  valid  acts,  rules,
regulations,  orders  and directions of  any  legislative,
executive, administrative or judicial body known to it  to
be applicable to the Loan Agreement and this Indenture.

  VII.14.       Enforcement of Obligations of the Company;
Amendments.  Upon receipt of written notification from the
Trustee, the Pollution Control Corporation shall cooperate
with  the  Trustee  in  enforcing the  obligation  of  the
Company  to  pay or cause to be paid all the payments  and
other  costs and charges payable by the Company under  the
Loan  Agreement and on any Security Arrangement  on  which
the   Company  is  the  obligor.   The  Pollution  Control
Corporation  shall not enter into any agreement  with  the
Company  amending  the Loan Agreement  without  the  prior
written consent of the Trustee and the Bank and compliance
with  Sections  12.06  and  12.07  of  this  Indenture  (a
revision  to  Exhibit  A to the Loan Agreement  not  being
deemed an amendment for purposes of this Section).

  VII.15.      Further Instruments.  The Pollution Control
Corporation  shall,  upon the reasonable  request  of  the
Trustee,  from  time  to  time execute  and  deliver  such
further instruments and take such further action as may be
reasonable  and  as  may  be required  to  carry  out  the
purposes  of  this Indenture; provided, however,  that  no
such  instruments or actions shall pledge  the  credit  or
taxing  power  of  the  State of Arizona,  the  County  of
Coconino,  the Pollution Control Corporation or any  other
political subdivision of said State.

  VII.16.      No Disposition of Trust Estate.  Except  as
permitted   by  this  Indenture,  the  Pollution   Control
Corporation  shall  not  sell, lease,  pledge,  assign  or
otherwise dispose of or encumber its interest in the Trust
Estate and will promptly pay or cause to be discharged  or
make adequate provision to discharge any lien or charge on
any part thereof not permitted hereby.

  VII.17.      Financing Statements.  The Pollution Control
Corporation  and  the  Trustee shall  cooperate  with  the
Company  in  causing appropriate financing statements  and
continuation statements, naming the Trustee as pledgee  of
the   Receipts  and  Revenues  of  the  Pollution  Control
Corporation  from  the Loan Agreement  and  of  the  other
moneys pledged under the Indenture for the payment of  the
principal  of  and premium, if any, and  interest  on  the
Bonds,  and as pledgee and assignee of the balance of  the
Trust  Estate,  to  be  duly filed  and  recorded  in  the
appropriate  state and county offices as required  by  the
provisions of the Uniform Commercial Code or other similar
law  as  adopted  in the State of Arizona  and  any  other
applicable jurisdiction, as from time to time amended,  in
order  to  perfect  and  maintain the  security  interests
created by this Indenture.

  VII.18.       Tax  Covenants;  Rebate  Fund.   (a)   The
Pollution Control Corporation covenants for the benefit of
all  Owners  from time to time of the Bonds and  the  Bank
that  it  will not directly or indirectly use or  (to  the
extent  within  its  control),  permit  the  use  of,  the
proceeds  of  any of the Bonds or any other funds  of  the
Pollution Control Corporation, or take or omit to take any
other  action, if and to the extent that such use, or  the
taking or omission to take such action, would cause any of
the  Bonds  to be "arbitrage bonds" within the meaning  of
Section  148 of the Code or otherwise subject  to  federal
income  taxation by reason of Sections 103 and 141 through
150  of  the  Code  or Section 103 of the  1954  Code,  as
applicable,  and  any  applicable regulations  promulgated
thereunder.  To that end the Pollution Control Corporation
covenants  to comply with all covenants set forth  in  the
Tax  Agreement,  which  is hereby incorporated  herein  by
reference as though fully set forth herein.

  (a)     The Trustee shall establish and maintain a  fund
separate  from  any other fund established and  maintained
hereunder   designated  the  "Coconino   County,   Arizona
Pollution  Control Corporation Pollution Control Refunding
Revenue  Bonds,  1996  Series  B  (Tucson  Electric  Power
Company  Project) Rebate Fund" (herein called the  "Rebate
Fund").   Within  the  Rebate  Fund,  the  Trustee   shall
maintain such accounts as shall be directed by the Company
in  order  for the Pollution Control Corporation  and  the
Company   to  comply  with  the  provisions  of  the   Tax
Agreement.  Subject to the transfer provisions provided in
paragraph  (c) below, all money at any time  deposited  in
the Rebate Fund shall be held by the Trustee in trust,  to
the  extent required to satisfy the Rebate Requirement (as
defined  in the Tax Agreement), for payment to the  United
States  of America, and neither the Company, the Pollution
Control Corporation or the Owners shall have any rights in
or claim to such moneys.  All amounts deposited into or on
deposit  in  the  Rebate Fund shall be  governed  by  this
Section 7.08, by Section 6.04 of the Loan Agreement and by
the  Tax  Agreement.   The Trustee shall  conclusively  be
deemed to have complied with such provisions if it follows
the  directions  of the Company, including  supplying  all
necessary information in the manner set forth in  the  Tax
Agreement,  and shall not be required to take any  actions
thereunder in the absence of written directions  from  the
Company.

  (b)    Upon receipt of the Company's written instructions,
the Trustee shall remit part or all of the balances in the
Rebate  Fund  to  the  United States  of  America,  as  so
directed.   In  addition, if the Company so  directs,  the
Trustee  shall deposit moneys into or transfer moneys  out
of  the Rebate Fund from or into such accounts or funds as
directed  by the Company's written directions.  Any  funds
remaining in the Rebate Fund after all of the Bonds  shall
have  been paid and any Rebate Requirement shall have been
satisfied,  or provision therefor reasonably  satisfactory
to the Trustee shall have been made, and all amounts owing
to  the  Bank under the Reimbursement Agreement have  been
paid, shall be withdrawn and remitted to the Company.

  (c)     Notwithstanding any provision of this Indenture,
the  obligation  to  remit the Rebate Requirement  to  the
United  States  of America and to comply  with  all  other
requirements  of this Section 7.08, Section  6.04  of  the
Loan  Agreement  and the Tax Agreement shall  survive  the
payment of the Bonds and the satisfaction and discharge of
this Indenture.

  VII.19.      Notices of Trustee.  The Trustee shall give
notice  to both the Pollution Control Corporation and  the
Company  whenever it is required hereby to give notice  to
either  and, additionally, shall furnish to the  Pollution
Control  Corporation and the Company copies of any  notice
by  mailing  or  Publication given by it pursuant  to  any
provision hereof.

  VII.2      0. No Transfer of Security Arrangement.   The
Trustee  shall not sell, assign or transfer  any  Security
Arrangement  except  to  a successor  trustee  under  this
Indenture.


VIII                    DEFEASANCE

  VIII.11.      Defeasance.   If  the  Pollution   Control
Corporation shall pay or cause to be paid to the Owner  of
any  Bond secured hereby the principal of and premium,  if
any,  and  interest  due and payable,  and  thereafter  to
become due and payable, upon such Bond or, if not during a
Flexible  Rate  Period or Term Rate Period or  Fixed  Rate
Period, any portion of any Bond in the principal amount of
$100,000 or any integral multiple thereof, or, if during a
Flexible  Rate  Period or Term Rate Period or  Fixed  Rate
Period,  any portion of such Bond in the principal  amount
of  $5,000 or any integral multiple thereof (and,  in  the
case  of  a  Flexible Rate Period, in a minimum  principal
amount  of  $100,000), such Bond or portion thereof  shall
cease  to  be  entitled to any lien, benefit  or  security
under   this   Indenture.    If  the   Pollution   Control
Corporation shall pay or cause to be paid to the Owners of
all the Bonds secured hereby the principal of and premium,
if  any,  and interest due and payable, and thereafter  to
become due and payable, thereon, and shall pay or cause to
be  paid  all  other  sums  payable  hereunder  including,
without  limitation, amounts payable pursuant  to  Section
10.04 hereof, then, and in that case, the right, title and
interest  of the Trustee in and to the Trust Estate  shall
thereupon  cease,  terminate and  become  void.   In  such
event, the Trustee shall assign, transfer and turn over to
the   Company   the   Trust  Estate,  including,   without
limitation,  any surplus in the Bond Fund and any  balance
remaining  in any other fund created under this Indenture;
provided,  however,  that, if a  Security  Arrangement  on
which  the  Company shall not be an obligor is in  effect,
prior to any such assignment, transfer and turning over to
the Company as aforesaid, the Trustee shall deliver to the
Bank  a  notice  specifying the date of  such  assignment,
transfer  and turning over (which date shall not  be  less
than four (4) Business Days after the date of delivery  of
such notice), and if prior to such specified date the Bank
shall have delivered to the Trustee a notice stating  that
amounts  are  owed by the Company to the  Bank  under  the
Reimbursement  Agreement  and  have  not  been  paid,  the
Trustee,  prior  to  any  such  assignment,  transfer  and
turning over to the Company as aforesaid, shall pay to the
Bank an amount equal to the lesser of (a) the total amount
owed  by  the  Company to the Bank as  specified  in  such
notice  and  (b) the total amount remaining in  all  funds
created under this Indenture.

    All  or  any portion of Outstanding Bonds or,  if  not
during  a Flexible Rate Period, a Term Rate Period or  the
Fixed  Rate Period, portions of Bonds in principal amounts
of $100,000 or any integral multiple thereof or, if during
a  Flexible Rate Period, a Term Rate Period or  the  Fixed
Rate  Period,  portions of Bonds in principal  amounts  of
$5,000 or any integral multiple thereof (and, in the  case
of  a  Flexible Rate Period, in a minimum principal amount
of  $100,000),  shall prior to the maturity or  redemption
date  thereof  be  deemed to have  been  paid  within  the
meaning  and  with the effect expressed  in  this  Article
VIII, and the entire indebtedness of the Pollution Control
Corporation  with respect thereof shall be  satisfied  and
discharged, when

     (a)   in the event said Bonds or portions thereof have
  been  selected for redemption in accordance with Section
  3.02 hereof, the Trustee shall have given, or the Company
  shall have given to the Trustee in form satisfactory to it
  irrevocable instructions to give, on a date in accordance
  with  the  provisions of Section 3.03 hereof  notice  of
  redemption of such Bonds or portions thereof,

     (b)   there shall have been deposited with the Trustee
  either moneys in an amount which shall be sufficient, or,
  during the Fixed Rate Period, Government Obligations which
  shall  not  contain provisions permitting the redemption
  thereof at the option of the issuer, the principal of and
  the interest on which, when due, and without regard to any
  reinvestment thereof, will provide moneys which, together
  with  the moneys, if any, deposited with or held by  the
  Trustee,  shall  be  sufficient, to  pay  when  due  the
  principal of and premium, if any, and interest  (at  the
  Maximum Rate, if such deposit shall not be made during the
  Fixed Rate Period) due and to become due on said Bonds or
  portions thereof on and prior to the redemption date  or
  maturity  date  thereof, as the case may  be;  provided,
  however,  that  such  moneys shall constitute  Available
  Moneys  and that such Government Obligations either  (i)
  shall have been purchased with Available Moneys or, (ii)
  shall have been held by the Trustee for the period of time
  for which the moneys used for the purchase thereof would
  be  required to be so held in order for such  moneys  to
  constitute  Available  Moneys if such  moneys  had  been
  deposited  with  the Trustee and the  purchase  of  such
  Government Obligations were disregarded, and

     (c)   in the event said Bonds or portions thereof do not
  mature  and  are  not  to be redeemed  within  the  next
  succeeding sixty (60) days, the Company shall have given
  the  Trustee  in  form satisfactory  to  it  irrevocable
  instructions to give, as soon as practicable in the same
  manner  as  a notice of redemption is given pursuant  to
  Section 3.03 hereof, a notice to the holders of said Bonds
  or  portions thereof that the deposit required by clause
  (b)  above has been made with the Trustee and that  said
  Bonds or portions thereof are deemed to have been paid in
  accordance with this Article VIII and stating the maturity
  or redemption date upon which moneys are to be available
  for the payment of the principal of and premium, if any,
  and interest on said Bonds or portions thereof.

    Notwithstanding the foregoing, no Bond shall be deemed
paid  and discharged pursuant to this Section 8.01  during
any  period  when a Letter of Credit is in  effect  unless
written  evidence is received from S&P,  if  S&P  is  then
rating  the Bonds, and Moody's, if Moody's is then  rating
the  Bonds, that such defeasance will not adversely affect
the ratings on the Bonds.

   Neither the Government Obligations nor moneys deposited
with  the  Trustee  pursuant  to  this  Article  VIII  nor
principal  or  interest payments on  any  such  Government
Obligations  shall be withdrawn or used  for  any  purpose
other  than, and such Government Obligations,  moneys  and
principal or interest payments shall be held in trust for,
the  payment of the principal of and premium, if any,  and
interest  on said Bonds or portions thereof,  or  for  the
payment  of the purchase price of said Bonds in accordance
with  Section 13.03 hereof; provided, that, prior  to  the
Fixed Rate Date, such moneys, if not then needed for  such
purposes,  shall, to the extent practicable,  be  invested
and  reinvested in Government Obligations maturing  on  or
prior  to  the  earlier of (a) the date  moneys  shall  be
required  for  the purchase of Bonds pursuant  to  Section
13.03  hereof  and  (b)  the Interest  Payment  Date  next
succeeding  the  date of investment or  reinvestment,  and
interest  earned from such investments shall be paid  over
to the Company, as received by the Trustee, free and clear
of  any  trust,  lien or pledge hereunder;  and  provided,
further,  that,  during the Fixed Rate  Period,  any  cash
received from such principal or interest payments on  such
Government Obligations deposited with the Trustee, if  not
then  needed  for  such  purposes, shall,  to  the  extent
practicable, be invested in Government Obligations of  the
type  described  in  clause  (b)  of  the  next  preceding
paragraph  maturing at times and in amounts sufficient  to
pay  when  due the principal of and premium, if  any,  and
interest  to become due on said Bonds or portions  thereof
on  and  prior  to such redemption date or  maturity  date
thereof, as the case may be, and interest earned from such
reinvestments  shall  be  paid over  to  the  Company,  as
received by the Trustee, free and clear of any trust, lien
or  pledge  hereunder.  If payment of less  than  all  the
Bonds  is  to be provided for in the manner and  with  the
effect  provided in this Article VIII, the  Trustee  shall
select  such  Bonds  or portions of Bonds  in  the  manner
specified  by  Section  3.02  hereof  for  selection   for
redemption of less than all Bonds in the principal  amount
designated  to the Trustee by the Company.  If  the  Bonds
are  rated  by S&P or Moody's, Government Obligations  for
purposes  of this Section 8.01 shall be limited  to  those
described in clause (a) of such definition and at or prior
to  the  time of the deposit of any Government  Obligation
with  the  Trustee  pursuant to  this  Section  8.01,  the
Company  shall provide S&P and Moody's with a  certificate
of  an accountant or accounting firm as to the sufficiency
of   such  Government  Obligation  to  pay  when  due  the
principal of and premium, if any, and interest due and  to
become  due  as  set forth in clause (b) of the  preceding
paragraph.


IX                DEFAULTS AND REMEDIES

  IX.11.        Events of Default.  Each of the  following
events  shall  constitute  and  is  referred  to  in  this
Indenture as an "Event of Default":

     (a)   a failure to pay the principal of or premium, if
  any, on any of the Bonds when the same shall become  due
  and payable at maturity, upon redemption or otherwise;

     (b)   a failure to pay an installment of interest on any
  of the Bonds after such interest shall have become due and
  payable  for a period of two (2) Business Days, if  such
  failure shall occur in respect of interest determined at a
  Flexible Rate or a Variable Rate other than a Term Rate,
  or for a period of sixty (60) days, if such failure shall
  occur in respect of interest determined at a Term Rate or
  the Fixed Rate;

     (c)   a failure to pay an amount due in respect of  a
  tender  for purchase after such amount shall have become
  due and payable;

     (d)   a failure by the Pollution Control Corporation to
  observe and perform any covenant, condition, agreement or
  provision (other than as specified in clauses (a), (b) and
  (c)  of this Section 9.01) contained in the Bonds or  in
  this  Indenture  on  the part of the  Pollution  Control
  Corporation  to be observed or performed, which  failure
  shall  continue for a period of ninety (90)  days  after
  written  notice, specifying such failure and  requesting
  that  it  be  remedied, shall have  been  given  to  the
  Pollution  Control Corporation and the  Company  by  the
  Trustee, which may give such notice in its discretion and
  which  shall give such notice at the written request  of
  Owners  of not less than 25% in principal amount of  the
  Bonds then Outstanding or of the Bank, unless the Trustee,
  or the Trustee and Owners of a principal amount of Bonds
  not less than the principal amount of Bonds the Owners of
  which requested that such notice be given or the Bank, 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 Owners of such
  principal amount of Bonds or the Bank, as the case may be,
  shall  be deemed to have agreed to an extension of  such
  period if corrective action is initiated by the Pollution
  Control  Corporation, or the Company on  behalf  of  the
  Pollution Control Corporation, within such period and is
  being diligently pursued.

    Upon  the occurrence and continuance of any  Event  of
Default  described  in  clause (a),  (b)  or  (c)  of  the
preceding  paragraph, the Trustee may, and at the  written
request of Owners of not less than 25% in principal amount
of Bonds then Outstanding or of the Bank shall, by written
notice to the Pollution Control Corporation, the Bank  and
the  Company, declare the Bonds to be immediately due  and
payable,  whereupon  they shall, without  further  action,
become  and  be immediately due and payable,  anything  in
this   Indenture   or  in  the  Bonds  to   the   contrary
notwithstanding, and the Trustee shall give notice thereof
to  the Tender Agent and the Remarketing Agent, and  shall
give  notice  thereof by Mail to all Owners of Outstanding
Bonds;  provided, however, that so long as the  Letter  of
Credit shall be in effect and no drawing on the Letter  of
Credit  shall  have  been,  and shall  remain,  wrongfully
dishonored, the Trustee shall not declare the acceleration
of  the  maturity of the Bonds without the consent of  the
Bank.  In the case of an Event of Default described in the
preceding  paragraph occurring when a Security Arrangement
on which the Company shall not be the obligor is in effect
and  with  respect  to which the Trustee  is  required  to
accelerate the Bonds, the Trustee shall make the aforesaid
declaration on the first Business Day after the occurrence
of  such  Event  of Default that the Trustee  may  make  a
drawing  or drawings on such Security Arrangement  and  on
which  the proceeds of such drawing or drawings  shall  be
immediately available, but shall not make such declaration
prior  to such date.  With respect to an Event of  Default
described  in  the  preceding paragraph occurring  when  a
Security Arrangement on which the Company shall not be the
obligor  is  in  effect, but with  respect  to  which  the
Trustee  is  not  required to accelerate  the  Bonds,  the
Trustee may make the aforesaid declaration only on a  date
when  the Trustee may make a drawing or drawings  on  such
Security Arrangements.  Upon such declaration, interest on
the Bonds shall cease to accrue.

   The provisions of the preceding paragraph, however, are
subject, when no Security Arrangement on which the Company
shall  not  be  the  obligor shall be in  effect,  to  the
condition that if, after the principal of the Bonds  shall
have  been  so declared to be due and payable, and  before
any  judgment or decree for the payment of the moneys  due
shall   have  been  obtained  or  entered  as  hereinafter
provided, the Pollution Control Corporation shall cause to
be  deposited with the Trustee a sum sufficient to pay all
matured  installments of interest upon all Bonds  and  the
principal of any and all Bonds which shall have become due
otherwise  than  by  reason  of  such  declaration   (with
interest   upon   such  principal  and,  to   the   extent
permissible  by law, on overdue installments of  interest,
at the rate per annum borne by the Bonds) and such amounts
as  shall  be  sufficient to cover reasonable compensation
and  reimbursement of expenses payable to the Trustee  and
any   predecessor  Trustee,  and  all  Events  of  Default
hereunder other than nonpayment of the principal of  Bonds
which shall have become due by said declaration shall have
been  remedied, then, in every such case,  such  Event  of
Default  shall  be deemed waived and such declaration  and
its  consequences rescinded and annulled, and the  Trustee
shall   promptly  give  written  notice  of  such  waiver,
rescission   and   annulment  to  the  Pollution   Control
Corporation,  the  Company,  the  Tender  Agent  and   the
Remarketing  Agent, and, if notice of the acceleration  of
the  Bonds  shall  have been given to the  Owners  of  the
Bonds, shall give notice thereof by Mail to all Owners  of
Outstanding  Bonds;  but  no such waiver,  rescission  and
annulment  shall extend to or affect any subsequent  Event
of  Default  or  impair  any right  or  remedy  consequent
thereon.

  IX.12.         Remedies.    Upon  the   occurrence   and
continuance  of any Event of Default, then  and  in  every
such case the Trustee in its discretion may, and upon  the
written request of the Bank or Owners of not less than 25%
in  principal  amount  of the Bonds then  Outstanding  and
receipt of indemnity to its satisfaction shall, in its own
name and as the Trustee of an express trust:

     (a)   by mandamus, or other suit, action or proceeding at
  law or in equity, enforce all rights of the Owners of the
  Bonds, and require the Pollution Control Corporation, the
  Bank or the obligor on any other Security Arrangement or
  the  Company to carry out any agreements with or for the
  benefit of such Owners and to perform its or their duties
  under the Act, the Loan Agreement, the Letter of Credit or
  other Security Arrangement and this Indenture;

     (b)   bring suit upon the Bonds; or

     (c)   by action or suit in equity enjoin any acts  or
  things which may be unlawful or in violation of the rights
  of the Owners of the Bonds.

   The Trustee shall give to the Bank prompt notice of its
election  of  any  one or more of the foregoing  remedies,
anything herein to the contrary notwithstanding,  so  long
as  the Letter of Credit shall be in effect and no drawing
on the Letter of Credit shall have been, and shall remain,
wrongfully dishonored, the Trustee shall not pursue any of
such remedies without the consent of the Bank.

  IX.13.       Restoration to Former Position.  In the event
that  any  proceeding taken by the Trustee to enforce  any
right under this Indenture shall have been discontinued or
abandoned  for  any reason, or shall have been  determined
adversely  to  the  Trustee, then  the  Pollution  Control
Corporation, the Trustee and the Owners shall be restored,
subject to any determination in such proceeding, to  their
former  positions and rights hereunder, respectively,  and
all  rights,  remedies  and powers of  the  Trustee  shall
continue as though no such proceeding had been taken.

  IX.14.         Bank's   or  Owners'  Right   to   Direct
Proceedings.   Anything in this Indenture to the  contrary
notwithstanding,  the  Bank or Owners  of  a  majority  in
principal  amount of the Bonds then Outstanding  hereunder
shall have the right, by an instrument in writing executed
and  delivered to the Trustee, to direct the time,  method
and place of conducting all remedial proceedings available
to  the  Trustee  under this Indenture or  exercising  any
trust or power conferred on the Trustee by this Indenture;
provided, however, that the Bank shall have no such rights
in  respect  of  remedies against the Bank; and  provided,
further,  that such direction shall not be otherwise  than
in   accordance  with  law  and  the  provisions  of  this
Indenture  and that the Trustee shall have the right  (but
not   the  obligation)  to  decline  to  follow  any  such
direction if the Trustee, being advised by counsel,  shall
determine  that the action or proceeding so  directed  may
not  lawfully  be taken, or if the Trustee in  good  faith
shall determine that the action or proceedings so directed
would involve the Trustee in personal liability or if  the
Trustee  in good faith shall so determine that the actions
or forbearances specified in or pursuant to such direction
would be unduly prejudicial to the interests of Owners not
joining  in  the  giving  of  said  direction,  it   being
understood  that  the  Trustee  shall  have  no  duty   to
ascertain whether or not such actions or forbearances  are
unduly  prejudicial to such Owners.  In  the  event  of  a
conflict  between the directions of the Bank and those  of
the  Owners of the Bonds, so long as the Letter of  Credit
shall  be in effect and no drawing on the Letter of Credit
shall  have  been, and shall remain wrongfully dishonored,
the  directions of the Bank shall prevail; otherwise,  the
directions of the Owners of the Bonds shall prevail.

  IX.15.        Limitation on Owners' Right  to  Institute
Proceedings.   No Owner of Bonds shall have any  right  to
institute any suit, action or proceeding in equity  or  at
law for the execution of any trust or power hereunder,  or
any  other remedy hereunder or on said Bonds, unless  such
Owner  previously shall have given to the Trustee  written
notice of an Event of Default as hereinabove provided  and
unless the Owners of not less than 25% in principal amount
of  the  Bonds  then Outstanding shall have  made  written
request  of  the  Trustee so to do,  after  the  right  to
institute  said  suit,  action or  proceeding  shall  have
accrued,  and shall have afforded the Trustee a reasonable
opportunity to proceed to institute the same in either its
or  their  name,  and unless there also  shall  have  been
offered to the Trustee security and indemnity satisfactory
to  it  against the costs, expenses and liabilities to  be
incurred  therein  or thereby, and the Trustee  shall  not
have  complied with such request within a reasonable time;
and  such notification, request and offer of indemnity are
hereby  declared in every such case, at the option of  the
Trustee, to be conditions precedent to the institution  of
said  suit, action or proceeding; it being understood  and
intended  that no one or more of the Owners of  the  Bonds
shall  have  any right in any manner whatever  by  his  or
their  action to affect, disturb or prejudice the security
of  this  Indenture, or to enforce any right hereunder  or
under the Bonds, except in the manner herein provided, and
that  all  suits, actions and proceedings  at  law  or  in
equity  shall  be  instituted, had and maintained  in  the
manner  herein provided and for the equal benefit  of  all
Owners of the Bonds.  No Owner of any Bond shall have  any
right to make a drawing on a Security Arrangement on which
the  Company shall not be the obligor or to institute  any
suit, action or proceeding in equity or at law against the
Bank  to  enforce a drawing on a Security  Arrangement  on
which the Company shall not be the obligor.

  IX.16.        No Impairment of Right to Enforce Payment.
Notwithstanding any other provision in this Indenture, the
right  of  any Owner of a Bond to receive payment  of  the
principal  of  and premium, if any, and interest  on  such
Bond,  on  or  after  the respective due  dates  expressed
therein, or to institute suit for the enforcement  of  any
such payment on or after such respective dates, shall  not
be impaired or affected without the consent of such Owner.

  IX.17.       Proceedings by Trustee without Possession of
Bonds.  All rights of action under this Indenture or under
any  of the Bonds secured hereby which are enforceable  by
the  Trustee may be enforced by it without the  possession
of  any  of  the Bonds, or the production thereof  on  the
trial or other proceedings relative thereto, and any  such
suit, action or proceeding instituted by the Trustee shall
be  brought in its name for the equal and ratable  benefit
of  the Owners of the Bonds, subject to the provisions  of
this Indenture.

  IX.18.        No  Remedy  Exclusive.  No  remedy  herein
conferred upon or reserved to the Trustee or to the Owners
of  the  Bonds  is intended to be exclusive of  any  other
remedy  or remedies, and each and every such remedy  shall
be  cumulative,  and shall be in addition to  every  other
remedy given hereunder, under the Loan Agreement or  under
any Security Arrangement, now or hereafter existing at law
or in equity or by statute.

  IX.19.       No Waiver of Remedies.  No delay or omission
of  the Trustee or of any Owner of a Bond to exercise  any
right or power accruing upon any default shall impair  any
such  right or power or shall be construed to be a  waiver
of any such default, or an acquiescence therein; and every
power  and remedy given by this Article IX to the  Trustee
and  to  the  Owners  of the Bonds, respectively,  may  be
exercised from time to time and as often as may be  deemed
expedient.

  IX.2 0. Application of Moneys.  Any moneys received by the
Trustee,  by  any  receiver or by  any  Owner  of  a  Bond
pursuant  to  any  right given or action taken  under  the
provisions of this Article IX, after payment of the  costs
and   expenses  of  the  proceedings  resulting   in   the
collection  of such moneys and of all amounts due  to  the
Trustee  and  any predecessor Trustee under Section  10.04
hereof, shall be deposited in the Bond Fund and all moneys
so deposited in the Bond Fund during the continuance of an
Event  of  Default (other than moneys for the  payment  of
Bonds  which had matured or otherwise become payable prior
to  such  Event of Default or for the payment of  interest
due  prior  to such Event of Default) shall be applied  as
follows  (provided,  however,  that  any  drawing  by  the
Trustee  on  any Security Arrangement for the  payment  of
principal of, or premium, if any, or interest on the Bonds
shall  be applied only to the payment of the principal  of
or  premium, if any, or interest on the Bonds pursuant  to
the terms of the Security Arrangement):

     (a)   Unless the principal of all the Bonds shall have
  become due and payable, all such moneys shall be applied
  (i) first, to the payment to the persons entitled thereto
  of  all  installments of interest then due on the Bonds,
  with interest on overdue installments, if lawful, at the
  rate  per  annum  borne by the Bonds, in  the  order  of
  maturity of the installments of such interest and, if the
  amount available shall not be sufficient to pay in  full
  any  particular  installment of interest,  then  to  the
  payment  ratably, according to the amounts due  on  such
  installment,  and  (ii) second, to the  payment  to  the
  persons entitled thereto of the unpaid principal of any of
  the  Bonds which shall have become due (other than Bonds
  called for redemption for the payment of which money  is
  held pursuant to the provisions of this Indenture), with
  interest on such Bonds at their rate from the respective
  dates  upon  which they became due and,  if  the  amount
  available shall not be sufficient to pay in full Bonds due
  on any particular date, together with such interest, then
  to  the  payment  ratably, according to  the  amount  of
  principal and interest due on such date, in each case to
  the persons entitled thereto, without any discrimination
  or privilege; provided, however, that moneys derived from
  the rights of the Trustee under any Security Arrangement
  on which the Company shall not be the obligor shall not be
  applied to the payment of the principal of or premium, if
  any, or interest on Bonds held of record by the Company,
  or  by  the Tender Agent for the account of the  Company
  pursuant  to  Section 13.07(c) hereof, if such  Security
  Arrangement prohibits by its terms a drawing  thereunder
  for such purpose.

     (b)   If the principal of all the Bonds shall have become
  due and payable, all such moneys shall be applied to the
  payment of the principal and interest then due and unpaid
  upon  the  Bonds, with interest on overdue interest  and
  principal, as aforesaid, without preference or priority of
  principal over interest or of interest over principal, or
  of any installment of interest over any other installment
  of interest, or of any Bond over any other Bond, ratably,
  according  to the amounts due respectively for principal
  and interest, to the persons entitled thereto without any
  discrimination  or  privilege; provided,  however,  that
  moneys derived from the rights of the Trustee under  any
  Security Arrangement in which the Company shall not be the
  Obligor  shall  not  be applied to the  payment  of  the
  principal of or premium, if any, or interest on Bonds held
  of record by the Company, or by the Tender Agent for the
  account  of  the  Company pursuant to  Section  13.07(c)
  hereof,  if such Security Arrangement prohibits  by  its
  terms a drawing thereunder for such purpose.

     (c)   If the principal of all the Bonds shall have come
  due and payable, and if acceleration of the maturity  of
  the  Bonds  by  reason of such Event  of  Default  shall
  thereafter  have been rescinded and annulled  under  the
  provisions  of  this Article IX, then,  subject  to  the
  provisions of clause (b) of this Section 9.10 which shall
  be applicable in the event that the principal of all the
  Bonds shall later become due and payable, the moneys shall
  be applied in accordance with the provisions of clause (a)
  of this Section 9.10.

  IX.22.       Severability of Remedies.  It is the purpose
and  intention  of this Article IX to provide  rights  and
remedies  to  the  Trustee and the  Owners  which  may  be
lawfully  granted under the provisions  of  the  Act,  but
should  any right or remedy herein granted be held  to  be
unlawful, the Trustee and the Owners shall be entitled, as
above  set forth, to every other right and remedy provided
in this Indenture and by law.


X    TRUSTEE; PAYING AGENT AND CO-PAYING AGENTS; REGISTRAR


  X.11.         Acceptance of Trusts.  The Trustee  hereby
accepts  and agrees to execute the trusts hereby  created,
but  only  upon  the additional terms set  forth  in  this
Article   X,  to  all  of  which  the  Pollution   Control
Corporation  agrees  and the respective  Owners  agree  by
their acceptance of delivery of any of the Bonds.

  X.12.          No  Responsibility  for  Recitals.    The
recitals, statements and representations contained in this
Indenture  or  in  the  Bonds,  save  only  the  Trustee's
authentication  upon  the  Bonds,  are  not  made  by  the
Trustee,  and the Trustee does not assume, and  shall  not
have, any responsibility or obligation for the correctness
of any thereof.  The Trustee makes no representation as to
the  validity  or  sufficiency of this  Indenture  or  the
Bonds.

  X.13.        Limitations on Liability.  The Trustee  may
execute any of the trusts or powers hereof and perform the
duties  required of it hereunder by or through  attorneys,
agents, receivers, or employees, and shall be entitled  to
advice of counsel concerning all matters of trust and  its
duty  hereunder, and the Trustee shall not  be  answerable
for the default or misconduct of any such attorney, agent,
receiver, or employee selected by it with reasonable care.
The  Trustee  shall not be answerable for the exercise  of
any  discretion  or  power under  this  Indenture  or  for
anything  whatsoever in connection with the trust  created
hereby, except only for its own negligence or bad faith.

     Anything   in   this  Indenture   to   the   contrary
notwithstanding, the Trustee shall in no event be required
to  expend  or  risk  its  own funds  or  otherwise  incur
personal financial liability in the performance of any  of
its  duties  or  in the exercise of any of its  rights  or
powers, if there shall be reasonable grounds for believing
that  the  repayment  of such funds or adequate  indemnity
against such liability is not reasonably assured to it.

  X.14.         Compensation, Expenses and Advances.   The
Trustee,  the  Paying Agent and any Co-Paying  Agent,  the
Registrar,  the  Tender  Agent and the  Remarketing  Agent
under  this  Indenture  shall be  entitled  to  reasonable
compensation  for their services rendered  hereunder  (not
limited by any provision of law regarding the compensation
of  the  trustee of an express trust) and to reimbursement
for their actual out-of-pocket expenses (including counsel
fees)  reasonably incurred in connection therewith  except
as  a  result of their negligence or bad faith, including,
without   limitation,  compensation   for   any   services
rendered, and reimbursement for any expenses incurred,  at
and  subsequent to the time the Bonds are deemed  to  have
been paid in accordance with Article VIII hereof.  If  the
Pollution Control Corporation shall fail to perform any of
the  covenants or agreements contained in this  Indenture,
other  than the covenants or agreements in respect of  the
payment  of  the  principal of and premium,  if  any,  and
interest   on   the  Bonds,  the  Trustee  may,   in   its
uncontrolled discretion and without notice to  the  Owners
of  the  Bonds,  at any time and from time to  time,  make
advances  to effect performance of the same on  behalf  of
the  Pollution Control Corporation, but the Trustee  shall
be  under  no  obligation so to do; and any and  all  such
advances  may  bear  interest at  a  rate  per  annum  not
exceeding  the  base  rate  then  in  effect  for   90-day
commercial  loans  by the Trustee or a commercial  banking
affiliate of the Trustee designated as such by the Trustee
in  the  city in which is located the Principal Office  of
the  Trustee (or such affiliate, as the case  may  be)  to
borrowers  of  the highest credit standing;  but  no  such
advance  shall  operate to relieve the  Pollution  Control
Corporation  from any default hereunder.  In Section  5.03
of the Loan Agreement, the Company has agreed that it will
pay  to  the Trustee (including any predecessor  Trustee),
the  Paying  Agent and any Co-Paying Agent, the Registrar,
the   Tender   Agent  and  the  Remarketing  Agent,   such
compensation  and reimbursement of expenses and  advances,
but the Company may, without creating a default hereunder,
contest  in  good  faith the reasonableness  of  any  such
services,  expenses and advances.  If  the  Company  shall
have  failed  to  make any payment to the Trustee  or  any
predecessor  Trustee  under  Section  5.03  of  the   Loan
Agreement and such failure shall have resulted in an Event
of  Default under the Loan Agreement, the Trustee, and any
predecessor Trustee, shall have, in addition to any  other
rights  hereunder,  a claim, prior to  the  claim  of  the
Owners,  for  the  payment  of its  compensation  and  the
reimbursement of its expenses and any advances made by it,
as  provided  in this Section 10.04, upon the  moneys  and
obligations  in  the  Bond Fund; provided,  however,  that
neither the Trustee nor any predecessor Trustee shall have
any  such  claim upon proceeds of drawings on  a  Security
Arrangement on which the Company shall not be the  obligor
or  upon  moneys or obligations deposited with or paid  to
the  Trustee for the redemption or payment of Bonds  which
are  deemed  to have been paid in accordance with  Article
VIII  hereof; and provided, further, that, so  long  as  a
Security Arrangement on which the Company shall not be the
obligor  is  in  effect,  neither  the  Trustee  nor   any
predecessor  Trustee shall have any such  claim  upon  any
moneys  or  obligations  in the Bond  Fund  unless,  after
satisfaction of such claim, there shall remain in the Bond
Fund  moneys  sufficient to pay all amounts  then  due  in
respect of the Bonds.

    In Section 5.04 of the Loan Agreement, the Company has
agreed  to  indemnify  the  Trustee  and  any  predecessor
Trustee to the extent provided therein.

  X.15.         Notice of Events of Default.  The  Trustee
shall not be required to take notice, or be deemed to have
notice,  of  any  default or Event of Default  under  this
Indenture other than an Event of Default under clause  (a)
or  (b)  of  the first paragraph of Section  9.01  hereof,
unless  an  officer assigned by the Trustee to  administer
its   corporate  trust  business  has  been   specifically
notified in writing of such default or Event of Default by
Owners  of  at least 25% in principal amount of the  Bonds
then  Outstanding or by the Bank, the Tender Agent or  the
Remarketing Agent.  The Trustee may, however, at any time,
in  its  discretion,  require  of  the  Pollution  Control
Corporation and the Company full information and advice as
to the performance of any of the covenants, conditions and
agreements contained herein.

  X.16.         Action by Trustee.  The Trustee  shall  be
under  no obligation to take any action in respect of  any
default  or  Event  of  Default hereunder  or  toward  the
execution  or  enforcement of any  of  the  trusts  hereby
created, or to institute, appear in or defend any suit  or
other proceeding in connection therewith, unless requested
in writing so to do by Owners of at least 25% in principal
amount of the Bonds then Outstanding or the Bank, and,  if
in  its  opinion  such action may tend to  involve  it  in
expense or liability, unless furnished, from time to  time
as  often  as it may require, with security and  indemnity
satisfactory  to  it;  provided,  however,  that  no  such
security  or  indemnity  shall be required  prior  to  the
Trustee  taking  any  action  on  a  Security  Arrangement
(including  a  drawing on the Letter of Credit)  otherwise
required  by  the terms hereof, but the Trustee  shall  be
entitled  to  such security or indemnity  thereafter.  The
foregoing  provisions are intended only for the protection
of  the  Trustee, and shall not affect any  discretion  or
power  given  by any provisions of this Indenture  to  the
Trustee to take action in respect of any default or  Event
of  Default without such notice or request from the Owners
of  the  Bonds  or the Bank, or without such  security  or
indemnity.

  X.17.        Good Faith Reliance.  The Trustee shall  be
protected  and  shall  incur no  liability  in  acting  or
proceeding  in  good  faith upon any  resolution,  notice,
telegram, telex, facsimile transmission, request, consent,
waiver, certificate, statement, affidavit, voucher,  bond,
requisition or other paper or document which it  shall  in
good  faith believe to be genuine and to have been  passed
or  signed by the proper board, body or person or to  have
been  prepared  and  furnished  pursuant  to  any  of  the
provisions  of  this Indenture or the Loan  Agreement,  or
upon  the  written  opinion  of  any  attorney,  engineer,
accountant or other expert believed by the Trustee  to  be
qualified  in  relation  to the subject  matter,  and  the
Trustee  shall  be under no duty to make any investigation
or  inquiry  as  to  any statements contained  or  matters
referred  to  in any such instrument, but may  accept  and
rely upon the same as conclusive evidence of the truth and
accuracy  of  such statements.  Neither the  Trustee,  the
Paying  Agent, any Co-Paying Agent, the Registrar nor  the
Tender Agent shall be bound to recognize any person as  an
Owner  of  a  Bond or to take any action  at  his  request
unless   the   ownership  of  such  Bond  is   proved   as
contemplated in Section 11.01 hereof.

  X.18.         Dealings in Bonds and with  the  Pollution
Control  Corporation and the Company.   The  Trustee,  the
Paying  Agent,  any  Co-Paying Agent, the  Registrar,  the
Tender  Agent or the Remarketing Agent, in its  individual
or  any other capacity, may in good faith buy, sell,  own,
hold  and  deal in any of the Bonds issued hereunder,  and
may  join in any action which any Owner of a Bond  may  be
entitled to take with like effect as if it did not act  in
any  capacity  hereunder.  The Trustee, the Paying  Agent,
any  Co-Paying Agent, the Registrar, the Tender  Agent  or
the  Remarketing  Agent, in its individual  or  any  other
capacity, either as principal or agent, may also engage in
or  be  interested  in any financial or other  transaction
with the Pollution Control Corporation or the Company, and
may act as depositary, trustee, or agent for any committee
or  body  of  Owners  of  Bonds secured  hereby  or  other
obligations of the Pollution Control Corporation as freely
as if it did not act in any capacity hereunder.

  X.19.        Allowance of Interest.  The Trustee may, but
shall not be obligated to, allow and credit interest  upon
any  moneys which it may at any time receive under any  of
the provisions of this Indenture, at such rate, if any, as
it  customarily allows upon similar funds of similar  size
and under similar conditions.  All interest allowed on any
such moneys shall be credited as provided in Articles  IV,
V and VI with respect to interest on investments.

  X.2   0.  Construction of Indenture.   The  Trustee  may
construe  any of the provisions of this Indenture  insofar
as  the  same  may appear to be ambiguous or  inconsistent
with  any other provision hereof, and any construction  of
any  such  provisions hereof by the Trustee in good  faith
shall be binding upon the Owners of the Bonds.

  X.21.         Resignation of Trustee.  The  Trustee  may
resign  and  be discharged of the trusts created  by  this
Indenture  by executing an instrument in writing resigning
such  trust  and specifying the date when such resignation
shall  take effect, and filing the same with the President
of  the Pollution Control Corporation, and with the Tender
Agent,  the Remarketing Agent, the Company and  the  Bank,
not  less  than  forty-five  (45)  days  before  the  date
specified  in such instrument when such resignation  shall
take  effect, and by giving notice of such resignation  by
Mail  to all Owners of Bonds.  Such resignation shall take
effect  on the later to occur of (i) the day specified  in
such  instrument and notice, unless previously a successor
Trustee shall have been appointed as hereinafter provided,
in   which  event  such  resignation  shall  take   effect
immediately upon the appointment of such successor Trustee
and (ii) the appointment of a successor Trustee.

    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 Pollution Control
Corporation  shall have delivered to the  Trustee  (i)  an
instrument appointing a successor Trustee, 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 in  accordance  with  Section
10.16,  the  Trustee shall be deemed to have  resigned  as
contemplated in this Section, the successor Trustee  shall
be  deemed  to have been appointed pursuant to  subsection
(b)  of Section 10.13 and such appointment shall be deemed
to  have  been accepted as contemplated in Section  10.16,
all  as  of  such date, and all other provisions  of  this
Article   X  shall  be  applicable  to  such  resignation,
appointment   and   acceptance  except   to   the   extent
inconsistent  with this paragraph.  The Pollution  Control
Corporation   shall   deliver  any  such   instrument   of
appointment at the direction of the Company.

  X.22.         Removal  of Trustee.  The Trustee  may  be
removed at any time by filing with the Trustee so removed,
and  with  the Pollution Control Corporation,  the  Tender
Agent,   the   Remarketing  Agent  and  the  Company,   an
instrument   or  instruments  in  writing,  appointing   a
successor,  or  an instrument or instruments  in  writing,
consenting  to  the  appointment by the Pollution  Control
Corporation  (at  the  direction  of  the  Company)  of  a
successor  and accompanied by an instrument of appointment
by  the Pollution Control Corporation (at the direction of
the  Company) of such successor, and in any event executed
by  Owners of not less than a majority in principal amount
of  the Bonds then Outstanding, such filing to be made  by
any Owner of a Bond or his duly authorized attorney.

  X.23.         Appointment of Successor Trustee.  (a)  In
case  at  any  time the Trustee shall be  removed,  or  be
dissolved,  or if its property or affairs shall  be  taken
under  the  control  of  any state  or  federal  court  or
administrative  body because of insolvency or  bankruptcy,
or  for  any other reason, then a vacancy shall  forthwith
and ipso facto exist and a successor may be appointed, and
in  case at any time the Trustee shall resign or be deemed
to  have  resigned, then a successor may be appointed,  by
filing  with the Pollution Control Corporation, the Tender
Agent, the Remarketing Agent and the Company an instrument
in  writing appointing such successor Trustee executed  by
Owners of not less than a majority in principal amount  of
Bonds  then  Outstanding, together with, so  long  as  the
Letter of Credit shall be in effect and no drawing on  the
Letter  of  Credit  shall  have been,  and  shall  remain,
wrongfully  dishonored, a consent  of  the  Bank  to  such
appointment   (such   consent  not  to   be   unreasonably
withheld).   Copies of such instrument shall  be  promptly
delivered  by  the  Pollution Control Corporation  to  the
predecessor  Trustee to the Trustee so appointed  and  the
Company.

  (a)    Until a successor Trustee shall be appointed by the
Owners  of  the Bonds as herein authorized, the  Pollution
Control Corporation, shall appoint a successor Trustee  as
directed  by  the Company with, so long as the  Letter  of
Credit shall be in effect and no drawing on the Letter  of
Credit  shall  have  been,  and shall  remain,  wrongfully
dishonored, the consent of the Bank (such consent  not  to
be  unreasonably withheld).  After any appointment by  the
Pollution  Control Corporation, it shall cause  notice  of
such  appointment  to be given by Mail to  all  Owners  of
Bonds.   Any  new  Trustee so appointed by  the  Pollution
Control  Corporation shall immediately and without further
act be superseded by a Trustee appointed by the Owners  of
the Bonds in the manner above provided.

  (b)     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.

  X.24.        Qualifications of Successor Trustee.  Every
successor  Trustee (a) shall be a bank  or  trust  company
duly organized under the laws of the United States or  any
state  or  territory thereof authorized by law to  perform
all  the duties imposed upon it by this Indenture and  (b)
shall  have (or the parent holding company of which  shall
have)  a  combined  capital stock, surplus  and  undivided
profits  of at least $100,000,000 if there can be located,
with  reasonable effort, such an institution  willing  and
able  to  accept  the  trust on reasonable  and  customary
terms.

  X.25.         Judicial Appointment of Successor Trustee.
In  case  at  any  time the Trustee shall  resign  and  no
appointment of a successor Trustee shall be made  pursuant
to the foregoing provisions of this Article X prior to the
date  specified in the notice of resignation as  the  date
when  such  resignation is to take  effect,  the  retiring
Trustee  may  forthwith  apply to  a  court  of  competent
jurisdiction  for the appointment of a successor  Trustee.
If  no  appointment of a successor Trustee shall  be  made
pursuant  to  the foregoing provisions of this  Article  X
within  six months after a vacancy shall have occurred  in
the  office of Trustee, any Owner of a Bond may  apply  to
any court of competent jurisdiction to appoint a successor
Trustee.  Such court may thereupon, after such notice,  if
any,  as  it  may  deem  proper and prescribe,  appoint  a
successor Trustee.

  X.26.         Acceptance of Trusts by Successor Trustee.
Any  successor Trustee appointed hereunder shall  execute,
acknowledge   and   deliver  to  the   Pollution   Control
Corporation   an  instrument  accepting  such  appointment
hereunder,  and thereupon such successor Trustee,  without
any  further  act, deed or conveyance, shall  become  duly
vested  with  all  the estates, property, rights,  powers,
trusts, duties and obligations of its predecessor  in  the
trust  hereunder, with like effect as if originally  named
Trustee  herein.   Upon  request  of  such  Trustee,  such
predecessor  Trustee and the Pollution Control Corporation
shall  execute  and deliver an instrument transferring  to
such  successor Trustee all the estates, property, rights,
powers  and  trusts hereunder of such predecessor  Trustee
and,  subject  to the provisions of Section 10.04  hereof,
such  predecessor Trustee shall pay over to the  successor
Trustee all moneys and other assets at the time held by it
hereunder.

  X.27.        Successor by Merger or Consolidation.   Any
corporation   or  association  into  which   any   Trustee
hereunder may be merged or converted or with which it  may
be   consolidated,  or  any  corporation  or   association
resulting  from any merger or consolidation to  which  any
Trustee hereunder shall be a party, shall be the successor
Trustee  under  this Indenture, without the  execution  or
filing of any paper or any further act on the part of  the
parties hereto, anything in this Indenture to the contrary
notwithstanding.

If,  at  the time any such successor to the Trustee  shall
succeed  to the trusts created by this Indenture,  any  of
the Bonds shall have been authenticated but not delivered,
such  successor  Trustee  may  adopt  the  certificate  of
authentication of any predecessor Trustee and deliver such
Bonds  so authenticated; and if at that time, any  of  the
Bonds  shall  not have been authenticated, such  successor
Trustee may authenticate such Bonds either in the name  of
any  such  predecessor hereunder or in the  name  of  such
successor;  and,  in all such cases, such  certificate  of
authentication  shall  have the full  force  which  it  is
anywhere  in the Bonds or in this Indenture provided  that
the  certificate  of authentication of the  Trustee  shall
have;  provided,  however, that the  right  to  adopt  the
certificate  of authentication of any predecessor  Trustee
or  to  authenticate Bonds in the name of any  predecessor
Trustee shall apply only to its successor or successors by
merger, conversion or consolidation.

  X.28.        Standard of Care.  Notwithstanding any other
provisions  of  this Article X, the Trustee shall,  during
the  existence of an Event of Default of which the Trustee
has  actual notice, exercise such of the rights and powers
vested in it by this Indenture and use the same degree  of
skill  and  care in their exercise as a prudent man  would
use and exercise under the circumstances in the conduct of
his own affairs.

  X.29.         Notice  to  Owners of Bonds  of  Event  of
Default.   If  an  Event of Default occurs  of  which  the
Trustee by Section 10.05 hereof is required to take notice
and  deemed to have notice, or any other Event of  Default
occurs of which the Trustee has been specifically notified
in  accordance  with Section 10.05 hereof,  and  any  such
Event  of  Default shall continue for at  least  two  days
after  the Trustee acquires actual notice thereof,  unless
the  Trustee  shall  have theretofore given  a  notice  of
acceleration pursuant to Section 9.01 hereof, the  Trustee
shall  give  notice  thereof  to  the  Tender  Agent,  the
Remarketing Agent and the Bank and give Notice by Mail  to
all Owners of Outstanding Bonds.

  X.3   0.  Intervention in Litigation  of  the  Pollution
Control Corporation.  In any judicial proceeding to  which
the Pollution Control Corporation is a party and which  in
the  opinion  of  the  Trustee  and  its  counsel  has   a
substantial  bearing on the interests  of  the  Owners  of
Bonds,  the Trustee may intervene on behalf of the  Owners
of   the  Bonds  and  shall,  upon  receipt  of  indemnity
satisfactory  to  it,  do so if requested  in  writing  by
Owners  of  at least 25% in principal amount of the  Bonds
then   Outstanding  if  permitted  by  the  court   having
jurisdiction in the premises.

  X.31.          Paying  Agent;  Co-Paying  Agents.    The
Pollution Control Corporation shall, with the approval  of
the  Company, appoint the Paying Agent for the  Bonds  and
may at any time or from time to time, with the approval of
the  Company, appoint one or more Co-Paying Agents for the
Bonds,  subject  to the conditions set  forth  in  Section
10.22  hereof.  The Paying Agent and each Co-Paying  Agent
shall  designate to the Trustee its Principal  Office  and
signify  its  acceptance  of the  duties  and  obligations
imposed  upon  it  hereunder by a  written  instrument  of
acceptance  delivered to the Pollution Control Corporation
and  the  Trustee in which such Paying Agent or  Co-Paying
Agent will agree, particularly:

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

     (b)    to  keep  such books and records as  shall  be
  consistent with prudent industry practice, to make  such
  books  and  records  available  for  inspection  by  the
  Pollution Control Corporation, the Trustee and the Company
  at  all reasonable times and, in the case of a Co-Paying
  Agent,  to  promptly furnish copies of  such  books  and
  records to the Paying Agent; and

     (c)   in the case of a Co-Paying Agent, upon the request
  of  the Paying Agent, to forthwith deliver to the Paying
  Agent all sums so held in trust by such Co-Paying Agent.

    The Pollution Control Corporation shall cooperate with
the  Trustee  and  the  Company  to  cause  the  necessary
arrangements  to  be  made and to be thereafter  continued
whereby  funds  derived  from  the  sources  specified  in
Sections  4.03 and 4.04 hereof will be made  available  to
the  Paying Agent and each Co-Paying Agent for the payment
when  due  of  the  principal of,  premium,  if  any,  and
interest on the Bonds.

  X.32.        Qualifications of Paying Agent and Co-Paying
Agents;  Resignation; Removal.  The Paying Agent  and  any

or  any  state  or  territory thereof, having  a  combined
capital  stock, surplus and undivided profits of at  least
$15,000,000  and  authorized by law  to  perform  all  the
duties  imposed upon it by this Indenture; provided  that,
if  the  Bonds  shall  be rated by  Moody's  and  if  such
corporation shall not be a bank or trust company, its long
term  debt  or  that of its parent shall  have  a  Moody's
rating  not lower than Baa3 or the equivalent thereof  and
its  short-term debt or that of its parent  shall  have  a
Moody's  rating  not  lower than  P-3  or  the  equivalent
thereof  unless,  in either case, there  shall  have  been
furnished  to  the  Pollution  Control  Corporation,   the
Trustee  and the Company written evidence from Moody's  to
the  effect  that  the appointment of the proposed  Paying
Agent or Co-Paying Agent will not, by itself, result in  a
reduction  or withdrawal of its ratings then in effect  on
the  Bonds.  The Paying Agent and any Co-Paying Agent  may
at  any  time resign and be discharged of the  duties  and
obligations created by this Indenture by giving  at  least
sixty   (60)   days'  notice  to  the  Pollution   Control
Corporation,  the  Company and the  Trustee.   The  Paying

at  the direction of the Company, by an instrument, signed
by  the  Pollution  Control Corporation,  filed  with  the
Paying Agent or such Co-Paying Agent, as the case may  be,
and with the Trustee.

    In  the  event  of the resignation or removal  of  the
Paying  Agent or any Co-Paying Agent, the Paying Agent  or

be  dissolved, or if the property or affairs of the Paying
Agent  shall  be taken under the control of any  state  or
federal court or administrative body because of bankruptcy
or  insolvency, or for any other reason, and the Pollution
Control Corporation shall not have appointed its successor
as Paying Agent, the Trustee shall ipso facto be deemed to
be  the  Paying  Agent for all purposes of this  Indenture
until the appointment by the Pollution Control Corporation
of the Paying Agent or successor Paying Agent, as the case
may be.

    Upon the appointment of a successor Paying Agent,  the
Trustee shall give notice thereof by Mail to all Owners of
Bonds.

  X.33.        Registrar.  The Pollution Control Corporation
shall,  with  the  approval of the  Company,  appoint  the
Registrar  for  the Bonds, subject to the  conditions  set
forth  in  Section  10.24  hereof.   The  Registrar  shall
designate to the Trustee its Principal Office and  signify
its acceptance of the duties imposed upon it hereunder  by
a  written  instrument  of  acceptance  delivered  to  the

books  and  records  as shall be consistent  with  prudent
industry  practice  and  to make such  books  and  records

arrangements  to  be  made and to be thereafter  continued
whereby   Bonds,   executed  by  the   Pollution   Control
Corporation  and  authenticated by the Trustee,  shall  be
made available for exchange, registration and registration
of transfer at the Principal Office of the Registrar.  The
Pollution  Control  Corporation shall cooperate  with  the
Trustee,  the  Registrar  and the  Company  to  cause  the
necessary arrangements to be made and thereafter continued
whereby the Paying Agent, any Co-Paying Agent, the  Tender
Agent  and  the Remarketing Agent shall be furnished  such
records and other information, at such times, as shall  be
required to enable the Paying Agent, such Co-Paying Agent,
the  Tender Agent and the Remarketing Agent to perform the
duties and obligations imposed upon them hereunder.

  X.34.         Qualifications of Registrar;  Resignation;
Removal.    The  Registrar  shall  be  a  corporation   or
association  duly organized under the laws of  the  United
States  of  America  or  any state or  territory  thereof,
having  a  combined capital stock, surplus  and  undivided
profits of at least $15,000,000 and authorized by  law  to
perform  all the duties imposed upon it by this Indenture.
The Registrar may at any time resign and be discharged  of
the  duties  and obligations created by this Indenture  by
giving  at  least sixty (60) days' notice to the Pollution
Control  Corporation, the Trustee and  the  Company.   The
Registrar may be removed at any time, at the direction  of
the  Company,  by  an instrument signed by  the  Pollution
Control  Corporation  filed with  the  Registrar  and  the
Trustee.

    In  the  event  of the resignation or removal  of  the
Registrar, the Registrar shall deliver any Bonds  held  by
it  in  such capacity to its successor or, if there be  no
successor, to the Trustee.

    In  the  event that the Pollution Control  Corporation
shall  fail to appoint a Registrar hereunder,  or  in  the
event that the Registrar shall resign or be removed, or be
dissolved, or if the property or affairs of the  Registrar
shall  be taken under the control of any state or  federal
court  or  administrative body because  of  bankruptcy  or
insolvency,  or  for any other reason, and  the  Pollution
Control Corporation shall not have appointed its successor
as Registrar, the Trustee shall ipso facto be deemed to be
the Registrar for all purposes of this Indenture until the
appointment  by the Pollution Control Corporation  of  the
Registrar or successor Registrar, as the case may be.

    Upon  the  appointment of a successor  Registrar,  the
Trustee shall give notice thereof by Mail to all Owners of
Bonds.

  X.35.        Several Capacities.  Anything herein to the
contrary  notwithstanding,  the  same  entity  may   serve
hereunder  as the Trustee, the Paying Agent or a Co-Paying
Agent, the Registrar, the Tender Agent and the Remarketing
Agent,  and in any combination of such capacities  to  the
extent permitted by law.


XI   EXECUTION OF INSTRUMENTS BY OWNERS OF BONDS AND
               PROOF OF OWNERSHIP OF BONDS

  XI.11.       Execution of Instruments; Proof of Ownership.
Any  request,  direction, consent or other  instrument  in
writing,  whether  or not required or  permitted  by  this
Indenture to be signed or executed by Owners of the Bonds,
may  be in any number of concurrent instruments of similar
tenor and may be signed or executed by Owners of the Bonds
or  by  an  agent appointed by an instrument  in  writing.
Proof  of the execution of any such instrument and of  the
ownership of Bonds shall be sufficient for any purpose  of
this  Indenture and shall be conclusive in  favor  of  the
Trustee  with regard to any action taken by it under  such
instrument if made in the following manner:

     (a)   The fact and date of the execution by any person of
  any such instrument may be proved by the certificate  of
  any officer in any jurisdiction who, by the laws thereof,
  has   power   to   take  acknowledgments   within   such
  jurisdiction, to the effect that the person signing such
  instrument acknowledged before him the execution thereof,
  or by an affidavit of a witness to such execution.

     (b)   The ownership or former ownership of Bonds shall be
  proved by the registration books kept under the provisions
  of Section 2.09 hereof.

   Nothing contained in this Article XI shall be construed
as  limiting the Trustee to such proof, it being  intended
that  the Trustee may accept any other evidence of matters
herein  stated which it may deem sufficient.  Any  request
or  consent of any Owner of a Bond shall bind every future
Owner of the same Bond or any Bond or Bonds issued in lieu
thereof in respect of anything done by the Trustee or  the
Pollution Control Corporation in pursuance of such request
or consent.


XII  MODIFICATION OF THIS INDENTURE AND THE LOAN AGREEMENT

  XII.11.      Limitations.  Neither this Indenture nor the
Loan Agreement shall be modified or amended in any respect
subsequent to the original issuance of the Bonds except as
provided  in  and in accordance with and  subject  to  the
provisions of this Article XII and Section 7.04 hereof.

    The  Trustee may, but shall not be obligated to, enter
into   any   Supplemental  Indenture  which  affects   the
Trustee's  own  rights,  duties or immunities  under  this
Indenture or otherwise.

  XII.12.        Supplemental  Indentures  without   Owner
Consent.   The  Pollution  Control  Corporation  and   the
Trustee  may,  from time to time and at any time,  without
the consent of or notice to the Owners of the Bonds, enter
into Supplemental Indentures as follows:

     (a)   to cure any formal defect, omission, inconsistency
  or  ambiguity in this Indenture, provided, however, that
  such cure shall not materially and adversely affect  the
  interests of the Owners of the Bonds;

     (b)   to grant to or confer or impose upon the Trustee for
  the  benefit  of the Owners of the Bonds any  additional
  rights, remedies, powers, authority, security, liabilities
  or  duties  which may lawfully be granted, conferred  or
  imposed;

     (c)    to add to the covenants and agreements of, and
  limitations and restrictions upon, the Pollution Control
  Corporation in this Indenture other covenants, agreements,
  limitations  and  restrictions to  be  observed  by  the
  Pollution Control Corporation;

     (d)   to confirm, as further assurance, any pledge under,
  and the subjection to any claim, lien or pledge created or
  to  be  created by, this Indenture, of the Receipts  and
  Revenues  of the Pollution Control Corporation from  the
  Loan  Agreement  or of any other moneys,  securities  or
  funds;

     (e)    to  authorize  a  different  denomination   or
  denominations  of  the  Bonds and  to  make  correlative
  amendments and modifications to this Indenture regarding
  exchange  ability  of Bonds of different  denominations,
  redemptions   of   portions  of  Bonds   of   particular
  denominations and similar amendments and modifications of
  a technical nature;

     (f)   to modify, alter, amend or supplement this Indenture
  in  any and all respects which may be correlative to any
  and   all  modifications,  alterations,  amendments  and
  supplements  to the Loan Agreement referred  to  in  the
  second paragraph of Section 12.06 hereof or which may be
  necessary,   desirable  or  appropriate  in   connection
  therewith (including without limitation the insertion of
  provisions relating to the priority of sources of funds to
  be used for the payment of the principal of and premium,
  if  any,  and  interest  on the Bonds,  changes  to  the
  provisions relating to the priority of sources of funds to
  be used for the purchase of Bonds, changes to the default
  provisions hereof and the insertion of provisions relating
  to the non-transferability and surrender of the evidence
  of  the  additional security referred to in  the  second
  paragraph of Section 12.06 hereof) or to carry  out  the
  purposes thereof; provided, however, that anything in this
  clause  (f)  of Section 12.02 or Section  12.06  to  the
  contrary    notwithstanding,   no   such   modification,
  alteration, amendment or supplement to this Indenture or
  the Loan Agreement shall render the Receipts and Revenues
  of  the  Pollution  Control Corporation  from  the  Loan
  Agreement (as such term is defined in this Indenture  as
  originally executed and delivered or as modified, altered,
  amended or supplemented) insufficient to pay the principal
  of and premium, if any, and interest on the Bonds;

     (g)   to modify, alter, supplement or amend this Indenture
  in  such manner as shall permit the qualification hereof
  under  the Trust Indenture Act of 1939, as from time  to
  time amended;

     (h)   to modify, alter, supplement or amend this Indenture
  in  such  manner  as  shall be necessary,  desirable  or
  appropriate  in  order to provide for or  eliminate  the
  registration and registration of transfer of  the  Bonds
  through a book-entry or similar method, whether or not the
  Bonds are evidenced by certificates;

     (i)   to provide a different method for the determination
  of the Daily Rate, Weekly Rate, Monthly Rate, Term Rate,
  Flexible Rates or the Fixed Rate if the method set forth
  herein is unavailable or unrealistic in the marketplace,
  but  only after notice thereof shall have been given  by
  Mail to all Owners of the Bonds;

     (j)   to modify, alter, amend or supplement this Indenture
  in  any other respect which is not materially adverse to
  the Owners and which does not involve a change described
  in  clause (i), (ii), (iii) or (iv) of Section  12.03(a)
  hereof;

     (k)   to provide any additional procedures, covenants or
  agreements necessary or desirable to maintain  the  tax-
  exempt status of interest on the Bonds; and

     (l)   to modify, alter, amend or supplement this Indenture
  in  any other respect, including amendments which  would
  otherwise be described in Section 12.03 hereof,  if  the
  effective date of such amendment is a date on which  all
  Bonds affected thereby are subject to mandatory tender for
  purchase pursuant to Section 2.02(h) or if Notice by Mail
  of  the  proposed amendment is given to  Owners  of  the
  affected Bonds at least 30 days before the effective date
  thereof and, on or before such effective date, such Owners
  have the right to demand purchase of their Bonds pursuant
  to Section 2.02(g) hereof.

    Before  the  Pollution  Control  Corporation  and  the
Trustee   shall  enter  into  any  Supplemental  Indenture
pursuant  to  this Section 12.02, there  shall  have  been
delivered  to  the  Trustee an  opinion  of  Bond  Counsel
stating that such Supplemental Indenture is authorized  or
permitted  by  this Indenture and the Act,  complies  with
their  respective  terms, will,  upon  the  execution  and
delivery  thereof, be valid and binding upon the Pollution
Control Corporation in accordance with its terms and  will
not, in and of itself, adversely affect the exclusion from
gross  income for federal tax purposes of the interest  on
the Bonds.

  XII.13.       Supplemental Indentures  with  Consent  of
Owners.  (a) Except for any Supplemental Indenture entered
into  pursuant  to Section 12.02 hereof,  subject  to  the
terms  and provisions contained in this Section 12.03  and
Section 12.05 and not otherwise, Owners of not less than a
majority  in aggregate principal amount of the Bonds  then
Outstanding  which  would  be adversely  affected  thereby
shall  have the right from time to time to consent to  and
approve  the  execution  and  delivery  by  the  Pollution
Control  Corporation and the Trustee of  any  Supplemental
Indenture  deemed necessary or desirable by the  Pollution
Control   Corporation  for  the  purposes  of   modifying,
altering,  amending, supplementing or rescinding,  in  any
particular,  any of the terms or provisions  contained  in
this  Indenture; provided, however, that, unless  approved
in writing by the Owners of all the Bonds then Outstanding
which  would be adversely affected thereby, nothing herein
contained shall permit, or be construed as permitting, (i)
a  change in the times, amounts or currency of payment  of
the  principal of or premium, if any, or interest  on  any
Outstanding Bond, a change in the purchase price  or  time
of  purchase  of  Bonds  tendered pursuant  to  the  terms
hereof,  a reduction in the principal amount or redemption
price of any Outstanding Bond or a change in the method of
determining   the  rate  of  interest  thereon,   or   any
impairment of the right of any Owner to institute suit for
the  payment of any Bond owned by it, or (ii) the creation
of  a claim or lien upon, or a pledge of, the Receipts and
Revenues  of  the Pollution Control Corporation  from  the
Loan  Agreement ranking prior to or on a parity  with  the
claim, lien or pledge created by this Indenture (except as
referred  to  in  Section  10.04  hereof),  or   (iii)   a
preference or priority of any Bond or Bonds over any other
Bond  or  Bonds,  or  (iv) a reduction  in  the  aggregate
principal  amount of Bonds the consent of  the  Owners  of
which  is required for any such Supplemental Indenture  or
which  is  required, under Section 12.07 hereof,  for  any
modification, alteration, amendment or supplement  to  the
Loan Agreement.

  (a)    If  at any time the Pollution Control Corporation
shall  request the Trustee to enter into any  Supplemental
Indenture  for any of the purposes of this Section  12.03,
the   Trustee   shall  cause  notice   of   the   proposed
Supplemental Indenture to be given by Mail to  all  Owners
of  Outstanding Bonds and to the Bank.  Such notice  shall
briefly  set forth the nature of the proposed Supplemental
Indenture and shall state that a copy thereof is  on  file
at  the Principal Office of the Trustee for inspection  by
all Owners of Bonds and by the Bank.

  (b)   Within two years after the date of the first mailing
of  such notice, the Pollution Control Corporation and the
Trustee  may  enter  into such Supplemental  Indenture  in
substantially  the form described in such notice  only  if
there  shall have first been delivered to the Trustee  (i)
the  required consents, in writing, of Owners of Bonds and
(ii)   an  opinion  of  Bond  Counsel  stating  that  such
Supplemental Indenture is authorized or permitted by  this
Indenture  and  the  Act, complies with  their  respective
terms  and, upon the execution and delivery thereof,  will
be   valid   and   binding  upon  the  Pollution   Control
Corporation  in  accordance with its terms  and  will  not
adversely   affect  the  exemption  from  federal   income
taxation of interest on the Bonds.

  (c)   If Owners of not less than the percentage of Bonds
required by this Section 12.03 shall have consented to and
approved  the  execution and delivery  thereof  as  herein
provided, no Owner shall have any right to object  to  the
execution and delivery of such Supplemental Indenture,  or
to  object  to  any of the terms and provisions  contained
therein  or  the operation thereof, or in  any  manner  to
question  the  propriety  of the  execution  and  delivery
thereof,  or  to enjoin or restrain the Pollution  Control
Corporation  or the Trustee from executing and  delivering
the  same  or  from  taking any  action  pursuant  to  the
provisions thereof.

  (d)    Subject to the terms and provisions contained  in
this subsection (e) of Section 12.03 and in Section 12.05,
the  Owners of all the Bonds at any time Outstanding shall
have the right, and the Pollution Control Corporation  and
the  Trustee  by  their  execution and  delivery  of  this
Indenture  hereby expressly confer upon  such  Owners  the
right to modify, alter, amend or supplement this Indenture
in any respect, including without limitation in respect of
the matters described in clauses (i), (ii), (iii) and (iv)
of the proviso contained in subsection (a) of this Section
12.03, by delivering to the Pollution Control Corporation,
the  Trustee  and  the  Company a  written  instrument  or
instruments,  executed  by or on behalf  of  such  Owners,
containing  a  form of Supplemental Indenture  which  sets
forth  such  modifications,  alterations,  amendments  and
supplements, and, upon the expiration of a thirty (30) day
period  commencing  on  the date of such  delivery  during
which no notice of objection shall have been delivered  by
the  Pollution  Control Corporation, the  Trustee  or  the
Company  to  such Owners at an address specified  in  such
written  instrument, such Supplemental Indenture shall  be
deemed  to  have  been  approved  and  confirmed  by   the
Pollution Control Corporation and the Trustee, to the same
extent  as  if  actually executed  and  delivered  by  the
Pollution Control Corporation and the Trustee, and to have
been  approved  by  the  Company,  and  such  Supplemental
Indenture  shall thereupon become and be for all  purposes
in  full  force and effect without further action  by  the
Pollution Control Corporation, the Trustee or the Company.
The  foregoing  provisions are, however,  subject  to  the
following conditions:

     (i)   no such Supplemental Indenture shall in any way
  affect  the  limited  nature of the obligations  of  the
  Pollution Control Corporation under this Indenture as set
  forth in Sections 2.06 and 7.01 hereof or shall adversely
  affect any of its rights hereunder;

     (ii)  no such Supplemental Indenture shall be to  the
  prejudice of the Paying Agent or any Co-Paying Agent, the
  Registrar, the Tender Agent or the Remarketing Agent; and

     (iii)       there  shall have been delivered  to  the
  Pollution Control Corporation, the Trustee and the Company
  an opinion of Bond Counsel stating that such Supplemental
  Indenture is authorized or permitted by this Indenture and
  the Act, complies with their respective terms, will, upon
  the expiration of the aforesaid thirty (30) day period, be
  valid and binding upon the Pollution Control Corporation
  in accordance with its terms and will not adversely affect
  the  exclusion of the interest on the Bonds  from  gross
  income for federal income tax purposes.

  XII.14.      Effect of Supplemental Indenture.  Upon the
execution  and  delivery  of  any  Supplemental  Indenture
pursuant  to the provisions of this Article XII (including
the  becoming  effective  of a Supplemental  Indenture  as
provided in Section 12.03(e) hereof), this Indenture shall
be,  and  be  deemed to be, modified, altered, amended  or
supplemented  in accordance therewith, and the  respective
rights, duties and obligations under this Indenture of the
Pollution  Control Corporation, the Trustee and Owners  of
all Bonds then Outstanding shall thereafter be determined,
exercised and enforced under this Indenture subject in all
respects  to  such modifications, alterations,  amendments
and supplements.

  XII.15.       Consent of the Company and  Obligor  under
Security  Arrangement.  Anything herein  to  the  contrary
notwithstanding,  any  Supplemental Indenture  under  this
Article  XII which affects any rights, powers,  agreements
or  obligations of the Company under the Loan Agreement or
of the obligor under any Security Arrangement, or requires
a   revision  of  the  Loan  Agreement  or  any   Security
Arrangement, shall not become effective unless  and  until
the  Company  or such obligor, as the case may  be,  shall
have consented to such Supplemental Indenture.

  XII.16.      Amendment of Loan Agreement without Consent
of Owners.  Without the consent of or notice to the Owners
of  the Bonds, the Pollution Control Corporation may enter
into any Supplemental Loan Agreement, and the Trustee  may
consent  thereto, as may be required (a) by the provisions
of  the  Loan  Agreement and this Indenture, (b)  for  the
purpose   of   curing   any   formal   defect,   omission,
inconsistency  or ambiguity therein, (c)  to  provide  any
additional  procedures, covenants or agreements  necessary
or desirable to maintain the tax-exempt status of interest
on  the  Bonds, or (d) in connection with any other change
therein  which is not materially adverse to the Owners  of
the  Bonds.  A revision of Exhibit A to the Loan Agreement
pursuant  to  Section 3.03 thereof shall not be  deemed  a
Supplemental   Loan  Agreement  for   purposes   of   this
Indenture.

   In addition to the foregoing, without the consent of or
notice  to the Owners of the Bonds, the Pollution  Control
Corporation  may  modify, alter, amend or  supplement  the
Loan Agreement, and the Trustee shall consent thereto,  in
any  and  all respects necessary, desirable or appropriate
in  connection  with the Termination, in  accordance  with
Section 6.07(c) of the Loan Agreement, or any provision of
any  Security Arrangement, including, without  limitation,
to  provide that the obligation of the Company to make (a)
the  Loan  Payments, (b) that portion of the Loan Payments
equal  to  the principal amount of the Bonds, or (c)  that
portion of the Loan Payments equal to the principal amount
of  the Bonds plus all or any portion of the Loan Payments
equal  to the premium, if any, and interest on the  Bonds,
shall  be  either evidenced or secured by  First  Mortgage
Bonds  issued and delivered to the Trustee.  In connection
with  any  such  modification,  alteration,  amendment  or
supplement  made  in connection with the delivery  to  the
Trustee  of  First Mortgage Bonds, (a) the First  Mortgage
Bonds shall (i) bear no interest, (ii) bear interest at  a
fixed  rate or (iii) bear interest at a rate equal to  the
rate of interest borne by the Bonds, as determined by  the
Company, (b) the First Mortgage Bonds shall be voted,  and
consents    shall   be   given   with   respect   thereto,
proportionately with what the Trustee reasonably  believes
will  be  the vote or consent of the holders of all  other
bonds outstanding under the Company Mortgage which vote or
consent,  or  otherwise as provided in such  modification,
alteration,  amendment  or  supplement,  (c)   the   First
Mortgage  Bonds  shall  be pledged  and  assigned  by  the
Pollution  Control Corporation to the Trustee as  part  of
the  Trust Estate and may be pledged and assigned  by  the
Pollution Control Corporation, secondarily and subject  to
the  rights of the Trustee therein, to the obligor on  any
other Security Arrangement as collateral security for  the
obligations of the Company to such obligor, and (d) to the
extent  that  the First Mortgage Bonds shall evidence  the
obligation  of the Company to make the Loan Payments,  the
obligation of the Company contained in the Loan  Agreement
to make the Loan Payments may be extinguished.

    The right of the Pollution Control Corporation to make
any  modification, alteration, amendment or supplement  to
the  Loan  Agreement  pursuant to the preceding  paragraph
shall  include  the  right  to  make  any  and  all   such
additional   modifications,  alterations,  amendments   or
supplements  to  the Loan Agreement as may  be  necessary,
desirable  or  appropriate to carry out the  purposes  set
forth in such paragraph.

    Before  the Pollution Control Corporation shall  enter
into,  and  the Trustee shall consent to, any Supplemental
Loan Agreement pursuant to this Section 12.06, there shall
have  been  delivered to the Trustee an  opinion  of  Bond
Counsel  stating that such Supplemental Loan Agreement  is
authorized  or permitted by this Indenture  and  the  Act,
complies  with  their  respective terms,  will,  upon  the
execution and delivery thereof, be valid and binding  upon
the  Pollution  Control Corporation  and  the  Company  in
accordance with its terms and will not, in and of  itself,
adversely  affect  the  exclusion from  gross  income  for
federal tax purposes of interest on the Bonds.

  XII.17.      Amendment of Loan Agreement with Consent of
Owners.    Except   in  the  case  of  Supplemental   Loan
Agreements  referred  to  in  Section  12.06  hereof,  the
Pollution  Control Corporation shall not enter  into,  and
the  Trustee  shall not consent to, any Supplemental  Loan
Agreement without the written approval or consent  of  the
Owners  of not less than a majority in aggregate principal
amount  of  the  Bonds  then Outstanding  which  would  be
adversely affected thereby, given and procured as provided
in  Section 12.03 hereof; provided, however, that,  unless
approved  in  writing  by the Owners  of  all  Bonds  then
Outstanding  which  would be adversely  affected  thereby,
nothing herein contained shall permit, or be construed  as
permitting,  a  change in the obligations of  the  Company
under  Section 5.01 of the Loan Agreement or a  change  in
the  obligations of the Company under Section 10.01(a)  of
the  Loan Agreement.  If at any time the Pollution Control
Corporation  or the Company shall request the  consent  of
the   Trustee  to  any  such  proposed  Supplemental  Loan
Agreement, the Trustee shall cause notice of such proposed
Supplemental Loan Agreement to be given in the same manner
as  provided  by  Section  12.03 hereof  with  respect  to
Supplemental  Indentures.  Such notice shall  briefly  set
forth  the  nature  of  such  proposed  Supplemental  Loan
Agreement  and  shall state that copies of the  instrument
embodying the same are on file at the Principal Office  of
the  Trustee for inspection by all Owners of the Bonds and
by  the Bank.  The Pollution Control Corporation may enter
into,  and  the Trustee may consent to, any such  proposed
Supplemental   Loan   Agreement  subject   to   the   same
conditions,  and  with  the same effect,  as  provided  by
Section   12.03   hereof  with  respect  to   Supplemental
Indentures.


XIII  TENDER  AGENT; REMARKETING AGENT;  PURCHASE  AND  RE
MARKETING OF BONDS

  XIII.11.     Tender Agent.  Subject to the conditions set
forth  in Section 13.02 hereof, the Tender Agent shall  be
appointed   by  the  Company.   The  Tender  Agent   shall
designate  its Principal Office and signify its acceptance
of the duties and obligations imposed upon it hereunder by
a  written  instrument  of  acceptance  delivered  to  the
Pollution   Control   Corporation,   the   Trustee,    the
Remarketing Agent, the Company and the Bank in  which  the
Tender Agent will agree, particularly:

     (a)    to hold all Bonds delivered to it for purchase
  hereunder  in  trust for the benefit of  the  respective
  Owners  which shall have so delivered such  Bonds  until
  moneys representing the purchase price of such Bonds shall
  have  been delivered to or for the account of or to  the
  order of such Owners;

     (b)   to hold all moneys delivered to it hereunder for the
  purchase of Bonds, other than moneys delivered to it  by
  the Company during the term of a Security Arrangement on
  which the Company shall not be the obligor, as agent and
  bailee of, and in escrow for the benefit of, the person or
  entity which shall have so delivered such moneys until the
  Bonds  to be purchased with such moneys shall have  been
  delivered to or for the account of such person or entity;

     (c)   to hold all moneys delivered to it by the Company
  for the purchase of Bonds in trust for the benefit of the
  Owners or former Owners who shall deliver Bonds to it for
  purchase until the Bonds purchased with such moneys shall
  have been delivered to or for the account of the Company;
  provided, however, that if the Bonds shall at  any  time
  become due and payable, the Tender Agent shall cause such
  moneys  (other  than  moneys held  pursuant  to  Section
  13.03(c) hereof) to be deposited into the Bond Fund;

     (d)   to hold Bonds for the account of the Company as and
  to  the  extent directed by the Bank as contemplated  by
  Section 13.07(c) hereof, such Bonds to be released to or
  upon the order of the Company upon receipt by the Tender
  Agent from the Bank of a written notice to the effect that
  such  Bonds  are released from any security interest  in
  favor of the Bank, the Letter of Credit is reinstated in
  full and that the Trustee is entitled to draw under  the
  Security Arrangement, to pay (i) principal of the  Bonds
  and the portion of purchase price equal to principal and
  (ii)  interest on the Bonds and the portion of  purchase
  price  equal to accrued interest, amounts equal  to  the
  amounts that could be drawn under a Security Arrangement
  if   the  drawing  made  to  purchase  such  Bonds  were
  disregarded (it being understood that, if so requested by
  the  Bank, the Tender Agent shall hold such Bonds in its
  capacity as custodian or collateral agent for the  Bank,
  subject  to any security interest of the Bank  therein);
  and, in the event of a redemption of any of such Bonds or
  the  acceleration of all Outstanding Bonds, to  hold  in
  trust moneys delivered to the Tender Agent in payment of
  the Bonds so held by it and to turn such moneys over  to
  the Bank to the extent of the amount specified by the Bank
  to the Tender Agent as the aggregate amount then owed by
  the Company to the Bank under the Reimbursement Agreement
  in respect of drawings under the Security Arrangement and
  interest thereon, any balance to be turned over  to  the
  Company;

     (e)   to give the notice specified in Section 2.10 hereof
  to the Owners of the Bonds; and

     (f)    to  keep  such books and records as  shall  be
  consistent with prudent industry practice and to make such
  books  and  records  available  for  inspection  by  the
  Pollution Control Corporation, the Trustee, the  Company
  and the Remarketing Agent at all reasonable times.

    The Pollution Control Corporation shall cooperate with
the Trustee, the Registrar, the Company, the Tender Agent,
the  Remarketing Agent and the Bank to cause the necessary
arrangements  to  be  made and to be thereafter  continued
whereby funds from the sources specified herein and in the
Loan Agreement will be made available for the purchase  of
Bonds  delivered  to the Principal Office  of  the  Tender
Agent for purchase in accordance with Section 2.02 hereof,
and  to otherwise enable the Tender Agent to carry out its
duties hereunder.

  XIII.12.      Qualifications of Tender Agent; Resignation;
Removal.   The  Tender Agent shall be a  corporation  duly
organized  under the laws of the United States of  America
or  any  state  or  territory thereof, having  a  combined
capital  stock, surplus and undivided profits of at  least
$100,000,000  and  authorized by law to  perform  all  the
duties  imposed upon it by this Indenture; provided  that,
if  the  Bonds  shall  be rated by  Moody's  and  if  such
corporation  shall  not be a bank or  trust  company,  its
long-term debt or that of its parent shall have a  Moody's
rating  not lower than Baa3 or the equivalent thereof  and
its  short-term debt or that of its parent  shall  have  a
Moody's  rating  not  lower than  P-3  or  the  equivalent
thereof  unless,  in either case, there  shall  have  been
furnished  to  the  Pollution  Control  Corporation,   the
Trustee  and the Company written evidence from Moody's  to
the  effect  that  the appointment of the proposed  Tender
Agent  will  not,  by itself, result  in  a  reduction  or
withdrawal  of  its ratings then in effect on  the  Bonds.
The  Tender Agent may at any time resign and be discharged
of the duties and obligations created by this Indenture by
giving  at  least sixty (60) days' notice to the Pollution
Control   Corporation,  the  Trustee,  the  Company,   the
Remarketing Agent and the Bank.  The Tender Agent  may  be
removed  at  any  time  by  an instrument  signed  by  the
Company,  filed  with  the  Tender  Agent,  and  with  the
Pollution   Control   Corporation,   the   Trustee,    the
Remarketing Agent and the Bank.

    In  the  event  of the resignation or removal  of  the
Tender Agent, the Tender Agent shall deliver any Bonds and
moneys held by it in such capacity to its successor or, if
there be no successor, to the Trustee.

    In the event that the Company shall fail to appoint  a
Tender Agent, or in the event that the Tender Agent  shall
resign  or be removed, or be dissolved, or if the property
or  affairs of the Tender Agent shall be taken  under  the
control  of  any  state or federal court or administrative
body because of bankruptcy or insolvency, or for any other
reason,  and  the  Company shall not  have  appointed  its
successor  as Tender Agent, the entity acting  as  Trustee
shall ipso facto be deemed to be the Tender Agent for  all
purposes  of this Indenture until the appointment  by  the
Company of the Tender Agent or successor Tender Agent,  as
the case may be.

  XIII.13.     Purchase of Bonds; Notices.  (a) On any date
Bonds are to be purchased pursuant to Section 2.02 hereof,
the  Tender Agent shall purchase, as agent and not for its
own  account, but only from the funds listed  below,  such
Bonds  from the Owners thereof at the applicable  purchase
price thereof specified in Section 2.02 hereof.  Funds for
the  payment of such purchase price shall be derived  from
the following sources in the order of priority indicated:

     (i)   moneys furnished by the Trustee to the Tender Agent
  pursuant to Section 8.01 hereof, such moneys to be applied
  only to the purchase of Bonds which are deemed to be paid
  in accordance with Article VIII hereof;

     (ii)  moneys furnished by the Company to the Tender Agent
  pursuant  to  Section 10.02 of the  Loan  Agreement  and
  proceeds  from the investment thereof, which  constitute
  Available Moneys;

     (iii)      proceeds of the sale of such Bonds pursuant to
  Section  13.06 hereof, provided such proceeds  are  made
  available or credited to the Tender Agent at or prior to
  the  last time the Trustee may demand payment of  moneys
  under any Security Arrangement;

     (iv)  moneys representing proceeds of a drawing on the
  Letter  of  Credit  or proceeds of  any  other  Security
  Arrangement; and

     (v)   moneys furnished by the Company to the Tender Agent
  pursuant to Section 10.01 of the Loan Agreement.

     (b)   (i) If moneys sufficient to pay the purchase price
  of Bonds tendered for purchase or required to be tendered
  for  purchase by their terms shall be held by the Tender
  Agent  on the date such Bonds are to be purchased,  such
  Bonds  shall be deemed to have been purchased,  for  all
  purposes of this Indenture, irrespective of whether or not
  such Bonds shall have been delivered to the Tender Agent,
  and  the  former  Owner or Owners shall  have  no  claim
  thereon, under this Indenture or otherwise, for any amount
  other than the purchase price thereof.

  (ii)  The Trustee shall authenticate and deliver to  the
  Tender  Agent  a  new  Bond or  Bonds  in  an  aggregate
  principal amount equal to the principal amount of  Bonds
  deemed  to  have been purchased in accordance with  this
  subsection (b) of Section 13.03 and bearing a number  or
  numbers  not contemporaneously outstanding.  Every  Bond
  authenticated   and  delivered  as   provided   in   the
  preceding  sentence  shall  be  entitled  to   all   the
  benefits  of  this Indenture equally and proportionately
  with  any  and  all  other Bonds duly issued  hereunder.
  The  Tender Agent shall maintain a record of  the  Bonds
  deemed  to  have  been  purchased as  provided  in  this
  subsection  (b)  of  Section 13.03,  together  with  the
  names and addresses of the former Owners thereof.

     (c)   In the event any Bonds shall not be presented for
  purchase  as provided in subsection (b) of this  Section
  13.03,  if moneys sufficient to purchase such Bonds  are
  held  by the Tender Agent for the benefit of the  former
  Owners thereof, the Tender Agent shall segregate and hold
  such  moneys  in trust, without liability  for  interest
  thereon,  for the benefit of the former Owners  of  such
  Bonds,  who  shall, except as provided in the  following
  sentence, thereafter be restricted exclusively  to  such
  fund or funds for the satisfaction of any claim for  the
  purchase price of such Bonds.  Any moneys which the Tender
  Agent shall segregate and hold in trust for the payment of
  the purchase price of any Bond and remaining unclaimed for
  one  year  after  the date of purchase shall,  upon  the
  Company's written request to the Tender Agent, be paid to
  the  Company; provided, however, that before the  Tender
  Agent shall be required to make any such repayment,  the
  Tender  Agent may, at the expense of the Company,  cause
  notice  to be given once by Mail to the former Owner  of
  such Bond or once by Publication, or both, to the effect
  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 the latest such notice,  any
  unclaimed balance of such moneys then remaining will  be
  paid to the Company.  After the payment of such unclaimed
  moneys to the Company, the former Owner of such Bond shall
  thereafter look only to the Company for the payment of the
  purchase price therefor, and all liability of the Tender
  Agent with respect to such moneys shall thereupon cease.

     (d)   (i) On any date Bonds are to be purchased pursuant
  to Section 2.02 and subsection (a) of this Section 13.03,
  the  Tender  Agent  shall give immediate  telephonic  or
  telegraphic  notice,  promptly confirmed  by  a  written
  notice, to the Remarketing Agent specifying the principal
  amount of Bonds delivered to it for purchase.

     (i)    On any date Bonds are to be purchased pursuant to
  Section  2.02 and subsection (a) of this Section  13.03,
  unless the Tender Agent shall have received a notice given
  by  the  Remarketing Agent pursuant to Section  13.06(b)
  hereof  indicating  that all Bonds to  be  sold  by  the
  Remarketing Agent pursuant to Section 13.06(a)  on  such
  date  have  been  remarketed and  that  all  remarketing
  proceeds have been received, the Tender Agent shall give
  telephonic or telegraphic notice no later than 11:15 a.m.,
  New  York  City time, promptly confirmed  by  a  written
  notice, to the Trustee and the Company which notice shall
  specify (A) the principal amount of the Bonds, if any, so
  sold by the Remarketing Agent and the remarketing proceeds
  thereof in its possession and (B) the amount to be drawn
  on  the  Letter of Credit or other Security Arrangement,
  and,  simultaneously therewith, the Tender  Agent  shall
  direct  the  Trustee to make drawings on the  Letter  of
  Credit  or  other Security Arrangement in such specified
  amount in accordance with Section 13.08 hereof.  In giving
  the  foregoing notice the Tender Agent shall utilize the
  information provided to it by the Remarketing Agent in the
  notice  required pursuant to Section 13.06(b); provided,
  however, that in the event that the Tender Agent shall not
  have received such notice from the Remarketing Agent prior
  to  the  Tender  Agent  being required  to  give  notice
  hereunder, the Tender Agent shall assume that such Bonds
  have not been remarketed.

  XIII.14.     Remarketing Agent.  Subject to the conditions
set  forth in Section 13.05 hereof, the Remarketing  Agent
shall  be appointed by the Company.  The Remarketing Agent
shall  designate  its  Principal Office  and  signify  its
acceptance of the duties and obligations imposed  upon  it
hereunder  by a written instrument of acceptance delivered
to  the  Pollution Control Corporation, the  Trustee,  the
Company  and  the  Tender Agent in which  the  Remarketing
Agent will agree, particularly:

     (a)   to hold all Bonds, if any, delivered to it hereunder
  as agent and bailee of, and in escrow for the benefit of,
  the  person or entity which shall have so delivered such
  Bonds until moneys representing the purchase price of such
  Bonds shall have been delivered to or for the account of
  or to the order of such person or entity;

     (b)    to  hold all moneys, if any, delivered  to  it
  hereunder for the purchase of Bonds as agent and  bailee
  of, and in escrow for the benefit of, the person or entity
  which shall have so delivered such moneys until the Bonds
  purchased with such moneys shall have been delivered to or
  for the account of such person or entity; and

     (c)    to  keep  such books and records as  shall  be
  consistent with prudent industry practice and to make such

  Pollution  Control Corporation, the Trustee, the  Tender
  Agent and the Company at all reasonable times.

    The Pollution Control Corporation shall cooperate with
the  Trustee, the Registrar, the Company, the Tender Agent
and   the   Remarketing  Agent  to  cause  the   necessary
arrangements  to  be  made and to be thereafter  continued
whereby   Bonds,   executed  by  the   Pollution   Control
Corporation  and  authenticated by the Trustee,  shall  be
delivered to the Remarketing Agent to the extent necessary
for  delivery  pursuant to Section 13.07  hereof,  and  to

States or any state or territory thereof having a combined
capital  stock, surplus and undivided profits of at  least
$15,000,000,  and, in either case, authorized  by  law  to
perform  all the duties imposed upon it by this Indenture;
provided that, if the Bonds shall be rated by Moody's  and
if  the proposed Remarketing Agent shall not be a bank  or
trust  company, its long-term debt or that of  its  parent
shall  have  a Moody's rating not lower than Baa3  or  the
equivalent thereof and its short-term debt or that of  its
parent  shall have a Moody's rating not lower than P-3  or

have  been furnished to the Pollution Control Corporation,
the  Trustee and the Company written evidence from Moody's
to   the  effect  that  the  engagement  of  the  proposed
Remarketing  Agent  will  not,  by  itself,  result  in  a
reduction  or withdrawal of its ratings then in effect  on
the  Bonds.  The Remarketing Agent may at any time  resign
and be discharged of the duties and obligations created by
this Indenture by giving at least thirty (30) days' notice
to  the  Pollution Control Corporation, the  Trustee,  the
Company,  the Tender Agent and the Bank.  The  Remarketing
Agent  may be removed at any time by an instrument, signed
by  the Company, filed with the Remarketing Agent and with
the  Trustee,  the  Tender Agent,  the  Pollution  Control

the Tender Agent.

    In  the event that the Company shall fail to engage  a
Remarketing  Agent  hereunder, or in the  event  that  the
Remarketing  Agent  shall resign  or  be  removed,  or  be
dissolved,   or  if  the  property  or  affairs   of   the

state  or federal court or administrative body because  of
bankruptcy or insolvency, or for any other reason, and the
Company   shall  not  have  appointed  its  successor   as

provisions  of the first paragraph of this Section  13.05,
shall ipso facto be deemed to be the Remarketing Agent for
all  purposes  of this Indenture until the appointment  by
the   Company  of  the  Remarketing  Agent  or   successor
Remarketing Agent, as the case may be; provided,  however,
that  the  Tender  Agent, in its capacity  as  Remarketing
Agent,  shall  not be required to sell Bonds  pursuant  to
Section  13.06  hereof  if  the  Tender  Agent  should  be
prohibited by law from conducting such activities.

(unless the Pollution Control Corporation, the Company  or
such  person  owns  all Bonds which are then  Outstanding,
determined without regard to this Section 14.05) shall  be
disregarded  and  deemed  not to be  Outstanding  for  the
purpose  of any such determination, except that,  for  the
purpose  of  determining  whether  the  Trustee  shall  be
protected  in  relying on any such direction,  consent  or
waiver,  only Bonds which the Trustee knows are  so  owned
shall be so disregarded.  Upon the request of the Trustee,
the  Company  and the Pollution Control Corporation  shall
furnish  to  the  Trustee  a certificate  identifying  all
Bonds,  if  any, actually known to either of  them  to  be
owned  or  held  by  or  for the account  of  any  of  the
above-described persons, and the Trustee shall be entitled
to  rely on such certificate as conclusive evidence of the
facts  set  forth  therein and that all  other  Bonds  are
Outstanding for the purposes of such determination.  Bonds
so  owned  which have been pledged in good  faith  may  be
regarded as Outstanding if the pledgee establishes to  the
satisfaction of the Trustee the pledgee's right so to  act
with respect to such Bonds and that the pledgee is not the
Pollution Control Corporation or the Company or any person
directly  or  indirectly controlling or controlled  by  or
under  direct or indirect common control with the Company;
provided,  however, that Bonds delivered to the  Bank,  or
held by the Tender Agent, pursuant to Section 14.07 hereof
shall  be  regarded as Outstanding for  purposes  of  this
Section 14.05.  In case of a dispute as to such right, any
decision  by the Trustee taken upon the advice of  counsel
shall be full protection to the Trustee.

  XIV.16.      Counterparts.  This Indenture may be executed

same Indenture.

  XIV.17.       Governing Law.  The laws of the  State  of

enforcement  of  the  rights and  duties  of  the  Trustee
hereunder and the construction of Section 14.09 hereof and
the computation of any period of grace provided herein.

Registered Owner:
Principal                                          Amount:
Dollars


   Coconino County, Arizona Pollution Control Corporation,
a  political  subdivision of the  State  of  Arizona  (the
"Pollution  Control  Corporation"),  for  value  received,
hereby  promises to pay (but only out of the Receipts  and
Revenues  of  the Pollution Control Corporation  from  the
Loan  Agreement, as hereinafter defined, and other  moneys
pledged therefor) to the Registered Owner identified above
or  registered  assigns, on the Maturity  Date  set  forth
above,  upon  the presentation and surrender  hereof,  the
Principal Amount set forth above and to pay (but only  out
of  the  Receipts  and Revenues of the  Pollution  Control
Corporation  from  the  Loan Agreement  and  other  moneys
pledged therefor), interest on said Principal Amount until
said Principal Amount has become due and payable, from the
Interest  Payment Date (as hereinafter defined)  to  which
interest  on this Bond shall have been paid in full  which
is, or immediately precedes, the date of authentication of
this  Bond or, if no interest shall have been paid on  the
Bonds,   from  the  date  of  original  issuance  thereof.
Interest  shall be paid on each Interest Payment Date  (as
hereinafter defined) at the rates determined as set  forth
in  the Indenture and described herein.  Interest on  this
Bond  will  be paid at the lesser of (a) a Daily  Rate,  a
Weekly Rate, a Monthly Rate, a Flexible Rate, a Term  Rate
or  the  Fixed Rate (each as defined in the Indenture)  as
selected in accordance with the Indenture and (b) 12%  per
annum.   Interest will be initially payable  at  a  Weekly
Rate.   While there exists an Event of Default  under  the
Indenture, the interest rate on the Bonds will be the rate
on  the  Bonds  on  the day before the  Event  of  Default
occurred,  except that if interest on the Bonds  was  then
payable  at Flexible Rates, the default rate will  be  the
highest Flexible Rate then in effect for any Bond.

  When interest is payable at a Variable Rate other than a
Term Rate or a Flexible Rate, interest will be computed on
the basis of the actual number of days elapsed over a year
of  365 days (366 in leap years).  When payable at a  Term
Rate  or the Fixed Rate, interest will be computed on  the
basis  of  a  360-day year of twelve 30-day  months.   For
purposes of any such calculation of interest payable  with
respect  to the final interest payment during a Term  Rate
Period  immediately followed by a Flexible, Daily,  Weekly
or Monthly Rate Period, the amount of interest which shall
be  payable  with  respect to such final  interest  period
shall  be  determined as if the Interest Payment Date  for
such  period  were  the  first  day  of  the  sixth  month
following    the   preceding   Interest   Payment    Date,
notwithstanding any extension of such month to  the  first
Business  Day  (as hereinafter defined) of such  month  by
reason  of the conversion to such Flexible, Daily,  Weekly
or Monthly Rate Period.

   As  used  in  this Bond, "Interest Payment Date"  means
(a)  when this Bond bears interest at the Daily or Monthly
Rate,  the  first Business Day of each calendar  month  to
which  interest at such rate has accrued,  (b)  when  this
Bond  bears interest at a Weekly Rate, the first Wednesday
of  each calendar month to which interest at such rate has
accrued, (c) when this Bond bears interest at a Term  Rate
or  the  Fixed  Rate, the first day of the sixth  calendar
month following the month in which the Term or Fixed  Rate
Conversion  Date (as defined in the Indenture) occurs  and
the  first day of each sixth calendar month thereafter  to
which  interest at such rate has accrued, except that  the
last  Interest Payment Date for any Term Rate Period which
is followed by a conversion to any type of Rate Period (as
defined below) (except a Term or Fixed Rate Period)  shall
be the first Business Day of the sixth month following the
preceding Interest Payment Date, (d) when this Bond  bears
interest at a Flexible Rate, the day after the last day of
each  Flexible  Rate Period applicable  thereto,  and  (e)
May 1, 2031.

  The regular record date ("Record Date") for any Interest
Payment  Date  shall  be  the close  of  business  on  the
(a) Business Day immediately preceding an Interest Payment
Date,  in  the case of Bonds bearing interest at Flexible,
Daily,   Weekly  and  Monthly  Rates,  and  (b)  fifteenth
(15th) day (whether or not a Business Day) of the calendar
month immediately preceding the Interest Payment Date,  in
the  case of Bonds bearing interest at a Term Rate or  the
Fixed Rate.

   As  used  in this bond, "Rate Period" means the  period
during which a particular rate of interest determined  for
the  Bonds as hereinafter provided is to remain in  effect
until  a subsequently determined rate of interest pursuant
to Article II of the Indenture becomes effective.

   Prior  to  any conversion of the interest rate  on  the
Bonds  to  the Fixed Rate, the Bonds may bear interest  at
Flexible  Rates or a Variable Rate effective for "Flexible
Rate  Periods" in the case of Flexible Rates and "Variable
Rate  Periods" in the case of Variable Rates  selected  by
the Company from time to time.  The rate of interest to be
borne by the Bonds during any particular Rate Period  will
be  determined  by the Remarketing Agent.  The  Bonds  may
bear interest as follows:

Variable Rates

   The Bonds may bear interest at a Variable Rate computed
on  a  Daily, Weekly, Monthly or Term basis in  accordance
with the applicable provisions of the Indenture.

  Daily Rate.

   While  the  Bonds bear interest at a  Daily  Rate,  the
interest  rate established for the Bonds will be effective
from day to day until changed by the Remarketing Agent.

  Weekly Rate.

  While the Bonds bear interest at a Weekly Rate, the rate
of interest on the Bonds will be determined on the Tuesday
or  next  Business Day immediately preceding the Wednesday
which  is the commencement date of the Weekly Rate  Period
by  the  Remarketing Agent to be effective for a seven-day
period  commencing  on such Wednesday and  ending  on  the
following Tuesday.

  Monthly Rate.

   While  the Bonds bear interest at a Monthly  Rate,  the
rate  of  interest  will  be  determined  monthly  by  the
Remarketing   Agent  on  the  Business   Day   immediately
preceding the commencement date of the Monthly Rate Period
to  which  it  relates  to be in effect  for  the  related
Monthly Rate Period.

  Term Rate.

   While  the  Bonds  bear interest at a  Term  Rate,  the
interest rate will be determined by the Remarketing  Agent
on the Business Day immediately preceding the commencement
date  of  the  Term Rate Period to which it relates,  such
interest  rate  to remain in effect for the  related  Term
Rate Period.

Flexible Rates

   While  the  Bonds bear interest at Flexible Rates,  the
interest  rate for each particular Bond will be determined
by the Remarketing Agent and will remain in effect for the
duration  (not  exceeding 270 days) of the  Flexible  Rate
Period  selected  for that Bond by the Remarketing  Agent.
While the Bonds bear interest at Flexible Rates, Bonds may
have  successive Flexible Rate Periods of any duration  up
to  270 days each and any Bond may bear interest at a rate
and for a period different from any other Bond.

Fixed Rate

  If the Bonds are to bear interest at the Fixed Rate, the
interest rate will be determined by the Remarketing  Agent
and  will remain in effect until the final maturity of the
Bonds.

   The duration and beginning and ending dates of any Rate
Period  may vary in the event of conversions between  Rate
Periods.  The type of Rate Period selected by the  Company
will  remain  in  effect until changed by the  Company  in
accordance with the Indenture.

   Bonds  which  bear interest at Flexible Rates  will  be
issued  in  the  determination of  $100,000  and  integral
multiples  of $5,000 in excess thereof.  Bonds which  bear
interest at a Daily, Weekly or Monthly Rate will be issued
in   denominations  of  $100,000  and  integral  multiples
thereof.   Bonds which bear interest at a  Term  or  Fixed
Rate  will  be  issued in the denomination of  $5,000  and
integral multiples thereof.

OPTIONAL TENDERS

    While this Bond bears interest at a Variable Rate  the
Registered Owner of this Bond has the right to tender this
Bond  for  purchase  at the principal amount  hereof  plus
accrued  and  unpaid  interest, if any,  as  follows:  (i)
during a Daily Rate Period on any Business Day prior to  a
conversion  from a Daily Rate Period to a  different  Rate
Period upon telephone notice to the Tender Agent not later
than  10:45 am., New York City time, on the purchase date,
(ii) during a Weekly Rate Period on any Business Day prior
to the conversion from a Weekly Rate Period to a different
Rate Period upon written or telephonic notice (in the case
of  telephonic notice promptly confirmed in writing by the
Registered Owner) to the Tender Agent not later than  5:00
p.m.,  New York City time, on a Business Day which is  not
fewer  than  seven days prior to the purchase date,  (iii)
during a Monthly Rate Period on any Interest Payment  Date

Business Day which is not fewer than fifteen days prior to
the  purchase date, all as more particularly  provided  in
the Indenture.

   The  Registered Owner of any Bond which such Registered
Owner   has  elected  to  tender  (as  described  in   the
Indenture)  and which is not tendered on the tender  date,
but  for  which there has been irrevocably deposited  with
the  Tender Agent an amount sufficient to pay the purchase
price  thereof,  shall  not be entitled  to  any  payment,
including  the payment of interest on such Bond after  the
tender date, other than the purchase price for such  Bond,
and  such Bond shall no longer be outstanding and entitled
to  the  benefits of the Indenture, except for the payment
of the purchase price of such Bond from moneys held by the
Tender  Agent  for such payment. On the tender  date,  the
Tender  Agent  shall  authenticate and deliver  substitute
Bonds in lieu of such untendered Bonds.

MANDATORY TENDERS

   This  Bond  shall  be subject to mandatory  tender  for
purchase  (i) while this Bond bears interest at a Flexible
Rate,  on  the day following the last day of each Flexible
Rate  Period  applicable to this Bond at a purchase  price
equal  to  100% of the principal amount hereof,  provided,
however,  that  this  Bond shall not be  subject  to  such
mandatory  tender for purchase if, prior to 3:00  p.m.  on
the  Business  Day next preceding the day  such  mandatory
tender  would otherwise occur, the Owner of this  Bond  by
notice  delivered  in  writing or by  telephone  (promptly
confirmed in writing) to the Remarketing Agent shall  have
elected  to  retain  this Bond for an additional  Flexible
Rate  Period  and  such Owner shall have agreed  with  the
Remarketing  Agent  as to the duration of  the  additional
Flexible Rate Period and the Flexible Rate to be effective
during  such  period,  (ii) on  the  Conversion  Date  (as
defined  in the Indenture) on which this Bond is converted
to  the Fixed Rate or from one Rate Period to another type
of  Rate Period (other than conversions between Daily  and
Weekly  Rate  Periods) or from any Term Rate Period  to  a
Term  Rate  Period of a different duration, at a  purchase
price  equal  to  100%  of the principal  amount  thereof,
(iii)  at  the  price  that would be the  then  applicable
redemption  price  set forth in the redemption  provisions
lettered  (a) or (c) below if such Bond were  redeemed  on
the  date of the tender, on the first day of the month  in
which  the  expiration or termination of the term  of  any
Security Arrangement (as hereinafter defined) shall occur;
provided,  however, that there shall be no such  mandatory
tender  if the Company shall have delivered to the  Tender
Agent  letters or certificates to the effect specified  in
Section  6.07(c) of the Loan Agreement, and  (iv)  on  the
first Business Day on which the Trustee may make a drawing
or drawings on a Security Arrangement on which the Company
shall not be the obligor and on which the proceeds of such
drawing  or  drawings shall be immediately available,  but
not  prior  to such date, on or after the receipt  by  the
Trustee of notice that either (a) following a drawing on a
Security Arrangement on which the Company shall not be the
obligor  to  pay  accrued  interest,  or  the  portion  of
purchase  price equal to accrued interest, on  the  Bonds,
that  the  amount available to be drawn on  such  Security
Arrangement will not be reinstated to the amount specified
in  the Indenture, or (b) an "Event of Default" under  the
Reimbursement  Agreement has occurred and  is  continuing,
unless  in  either such case, the notice received  by  the
Trustee also directs it to provide notice to the Pollution
Control Corporation of its obligation to redeem the  Bonds
pursuant to the Indenture.

   If an Owner of a Bond is required to tender its Bond as
set  forth  in the preceding paragraph such Bond  will  be
deemed to be purchased at the price set forth above on the
date   that   the  Bond  is  required  to   be   tendered,
notwithstanding  the  failure  of  the  Owner  thereof  to
deliver  the Bond to the Tender Agent.  If a  Bond  is  so
deemed  to be purchased, the Owner thereof at the time  of
such  purchase  shall  not  be  entitled  to  receive  any
interest accruing on such Bond on and after the date it is
deemed  to be purchased, and shall not be entitled to  any
benefits  under  the Indenture except  for  the  right  to
receive the purchase price for such Bond.

WRITTEN NOTICE OF CHANGE IN TYPE OF RATE PERIOD

   While this Bond bears interest at a Flexible Rate or at
a Variable Rate, the Tender Agent shall give notice to the
Owners  of  all Bonds of the conversion from one  type  of
Rate  Period to another type of Rate Period (or to a  Term
Rate  Period  from  a  Term Rate  Period  of  a  different
duration) at the times described in the Indenture.  If the
Company does not elect in a timely fashion to convert to a
new  type  of Rate Period for the Bonds (or to a different
Term  Rate Period for the Bonds) or any condition to  such
conversion under the Indenture is not satisfied, the  type
of  Rate Period then in effect will continue until changed
by  timely notice and, in the case of a Term Rate  Period,
the duration of the Term Rate Period shall be one year.

CONVERSION TO THE FIXED RATE

    The   Indenture  provides  that,  subject  to  certain
conditions,  the  Company has the  right  to  convert  the
interest  rate on this Bond to the Fixed Rate to maturity.
This  Bond  shall  be  subject  to  mandatory  tender  for
purchase  on  the Fixed Rate Conversion Date.   After  the
Fixed  Rate Conversion Date, the Owner of this Bond  shall
have no right to tender this Bond for purchase.

York,  National Association, as Paying Agent,  or  at  the
principal  office  of  any co-paying  agent  appointed  in
accordance  with  the  Indenture, at  the  option  of  the
registered Owner hereof.  Interest on this Bond is payable
by  check  drawn upon the Paying Agent and mailed  to  the
registered address of the registered owner of this bond as
of  the  close of business on the Record Date.  Except  in
respect  of a Term Rate Period and the Fixed Rate  Period,
owners  of  not  less than $1,000,000 aggregate  principal
amount  of  Bonds may request that interest on  the  Bonds
and,  after presentation and surrender of such Bonds,  the
principal  thereof be paid by wire transfer to an  account
maintained within the continental United States  specified
by  the  owner thereof.  Payment of the principal  of  and
premium,  if any, and interest on, and purchase price  of,
this  Bond shall be in any coin or currency of the  United
States  of America as, at the respective times of payment,
shall  be  legal  tender  for the payment  of  public  and
private debts.

   This  Bond  is  one  of  the duly authorized  Pollution
Control  Refunding Revenue Bonds, 1996  Series  B  (Tucson

control  facilities  (the  "Facilities")  at  the   Navajo
Generating  Station (the "Plant").  Pursuant to  the  Loan

between  the  Pollution  Control  Corporation  and  Tucson
Electric  Power  Company,  a  corporation  organized   and
existing  under  the  laws of the State  of  Arizona  (the
"Company"), the proceeds of the Bonds, other than  accrued
interest, if any, paid by the initial purchasers  thereof,
will be loaned from time to time to the Company.

  drawings  or  other demands for payment  on  a  Security
  Arrangement  (as  hereinafter  defined)  on  which   the
  Company shall not be the obligor, if any, are made,  are
  not  required  or  authorized to remain  closed  and  on
  which The New York Stock Exchange is not closed; and

     (b)  the term "Security Arrangement" means any letter
  of  credit, first mortgage bonds of the Company,  credit
  facility,  insurance  policy  or  other  credit  support
  agreement  or  mechanism  arranged  by  the  Company  to
  evidence  its  obligations under the Loan  Agreement  or
  for  the  purpose of securing the Bonds, but  shall  not
  include any facility, agreement or mechanism, such as  a
  liquidity  facility or line of credit, that  is  not  an
  irrevocable obligation to pay amounts in respect of  the
  obligations of the Company under the Loan Agreement.

  The Bonds are equally and ratably secured, to the extent
provided in the Indenture, by the pledge thereunder of the
"Receipts   and   Revenues  of   the   Pollution   Control
Corporation from the Loan Agreement", which term  is  used
herein  as  defined in the Indenture and which as  therein
defined  means all moneys paid or payable to  the  Trustee
for  the  account of the Pollution Control Corporation  by
the Company in respect of the loan payments, including all
moneys drawn by the Trustee under any Security Arrangement
in  satisfaction of the Company's obligation to  make  the
loan  payments,  and  all receipts of the  Trustee  which,
under  the provisions of the Indenture, reduce the amounts
of  such  payments. The Pollution Control Corporation  has
also  pledged and assigned to the Trustee as security  for
the  Bonds all other rights and interests of the Pollution
Control  Corporation under the Loan Agreement (other  than
its  rights  to  indemnification  and  his  administrative
expenses and certain other rights).

   The transfer of this Bond shall be registered upon  the
registration  books  kept  at  the  principal  office   of
_________________________________, as  Registrar,  at  the
written  request  of the registered owner  hereof  or  his
attorney  duly  authorized in writing, upon  surrender  of
this   Bond  at  said  office,  together  with  a  written
instrument of transfer satisfactory to the Registrar  duly
executed  by  the registered owner or his duly  authorized
attorney.

  The Company may, but is not obligated to, provide one or
more Security Arrangements in order to secure, evidence or
otherwise   further  its  obligations   under   the   Loan
Agreement.  The  Company has authorized and  directed  the
Trustee  to take action under any Security Arrangement  in
accordance with the terms thereof and of the Indenture.

   In  the  manner  and with the effect  provided  in  the
Indenture,  each  of the Bonds may be  redeemed  prior  to
maturity, as follows:

     (a)   When  interest  on  the  Bonds  is  payable  at
  Flexible  Rates  or a Variable Rate other  than  a  Term
  Rate,  the Bonds shall be subject to redemption  by  the
  Pollution Control Corporation, at the direction  of  the
  Company,  in whole at any time or in part from  time  to
  time,  at  the  principal amount  thereof  plus  accrued
  interest to the redemption date.

  redemption by the Pollution Control Corporation, at  the
  direction  of the Company, in whole at any time  at  the
  principal  amount thereof plus accrued interest  to  the
  redemption date, if:

           (i) the Company shall have determined that  the
     continued  operation of the Plant  is  impracticable,
     uneconomical or undesirable for any reason;

           (ii) the Company shall have determined that the
     continued    operation   of   the    Facilities    is
     impracticable, uneconomical or undesirable due to (A)
     the  imposition of taxes, other than ad valorem taxes
     currently  levied upon privately owned property  used
     for  the  same general purpose as the Facilities,  or
     other  liabilities  or burdens with  respect  to  the
     Facilities  or  operation  thereof:  (B)  changes  in
     technology,  in  environmental  standards  or   legal
     requirements  or  in  the  economic  availability  of
     materials,  supplies,  equipment  or  labor  or   (C)
     destruction  of  or  damage to all  or  part  of  the
     Facilities;

          (iii) all or substantially all of the Facilities
     or  the  Plant shall have been condemned or taken  by
     eminent domain; or

           (iv)  the  operation of the facilities  or  the
     Plant   shall  have  been  enjoined  or  shall   have
     otherwise been prohibited by, or shall conflict with,
     any order, decree, rule or regulation of any court or
     of  any  federal,  state  or local  regulatory  body,
     administrative agency or other governmental body.

     (c)  When interest on the Bonds is payable at a  Term
Rate  for a Term Rate Period of five years or more or  the

the Pollution Control Corporation, at the direction of the
Company,  on any day in whole at any time or in part  from

   Anything  herein or in the Indenture  to  the  contrary
notwithstanding,  in  the event  that  the  Company  shall
consolidate with, merge with or into, or sell or otherwise
transfer  all  or  substantially all  of  its  assets  to,
another corporation in accordance with Section 6.01 of the
Loan  Agreement, the Bonds shall be subject to  redemption
by  the Pollution Control Corporation, at the direction of
the Company, in whole, at any time prior to the first date
on  which  the  Bonds  are  redeemable  as  herein  before
provided,   at  the  redemption  price  which   would   be
applicable  on  such  date plus accrued  interest  to  the
redemption date.

   (d)  The Bonds shall be subject to mandatory redemption
by  the  Pollution Control Corporation, at  the  principal
amount  thereof  plus accrued interest to  the  redemption
date,  on  the 180th day (or such earlier date as  may  be
designated by the Company) after a final determination  by
a  court  of  competent jurisdiction or an  administrative
agency,  to  the effect that, as a result of a failure  by
the  Company to perform or observe any covenant, agreement
or  representation  contained in the Loan  Agreement,  the
interest  payable  on  the Bonds is included  for  Federal
income  tax  purposes in the gross income  of  the  owners
thereof,  other  than  any  owner  of  a  Bond  who  is  a
"substantial user" of the Facilities or a "related person"
within  the meaning of Section 103(b)(13) of the  Internal
Revenue  Code  of  1954,  as amended,  as  applicable.  No
determination by any court or administrative agency  shall
be considered final for the purposes of this paragraph (d)
unless the Company shall have been given timely notice  of
the proceeding which resulted in such determination and an
opportunity  to  participate in  such  proceeding,  either
directly  or  through an owner of a Bond,  and  until  the
conclusion of any appellate review sought by any party  to
such  proceeding or the expiration of the time for seeking
such  review. The Bonds shall be redeemed either in  whole
or  in  part  in such principal amount that  the  interest
payable  on  the  Bonds remaining outstanding  after  such
redemption  would not be included in the gross  income  of
any owner thereof, other than an owner of a Bond who is  a
"substantial user" of the Facilities or a "related person"
within the meaning of Section 103(b)(13) of the 1954 Code.


   (e)  The Bonds shall be subject to mandatory redemption
by  the  Pollution Control Corporation, at  the  principal
amount  thereof  plus accrued interest to  the  redemption
date,  upon  the  occurrence of either  of  the  following
events:

     (i)  receipt by the Trustee, following a drawing on a
  Security Arrangement on which the Company shall  not  be
  the  obligor to pay accrued interest, or the portion  of
  purchase price equal to accrued interest, on the  Bonds,
  of  notice from the Bank that the amount available to be
  drawn   on  such  Security  Arrangement  will   not   be
  reinstated  (in  respect  of  interest  or  portion   of
  purchase price equal to accrued interest) in the  amount
  of  such  drawing and directing the Trustee  to  provide
  notice  to  the  Pollution Control  Corporation  of  its
  resulting obligation to redeem the Bonds; or

     (ii)  receipt by the Trustee of notice from the  Bank
  stating   that   an   Event   of   Default   under   the
  Reimbursement Agreement (or other agreement between  the
  Company  and the Bank pursuant to which the Bank  issued
  and  delivered  to  the Trustee a Security  Arrangement)
  has   occurred  and  is  continuing  and  directing  the
  Trustee  to  provide  notice to  the  Pollution  Control
  Corporation  of its resulting obligation to  redeem  the
  Bonds.

  Upon the occurrence of either of the events described in
the immediately preceding paragraph, the Pollution Control
Corporation shall be obligated to redeem the Bonds on  the
first  Business Day after the occurrence of such event  on
which  the  Trustee may make a drawing or  drawings  on  a
Security Arrangement on which the Company shall not be the
obligor  and  on  which the proceeds of  such  drawing  or
drawings  shall  be available, but shall  not  redeem  the
Bonds prior to such date.

   The  provisions  of clause (e) of the second  preceding
paragraph  are subject to the condition that if either  of
the  events described in clause (i) or (ii) of the  second
preceding paragraph shall have occurred and if the Trustee
shall  thereafter have received notice from the  Bank  (a)
that  the  notice  which requires a  mandatory  redemption
pursuant  to  the  second  preceding  paragraph  has  been
withdrawn and (b) that the amounts available to  be  drawn
on  the  Security Arrangement to pay (i) the principal  of
the  Bonds  or  the  portion of purchase  price  equal  to
principal  and (ii) interest on the Bonds and the  portion
of  purchase  price  equal to accrued interest  have  been
reinstated then, in every such case, the event giving rise
to  such mandatory redemption shall be deemed to be waived
and all proceedings for such redemption shall be rescinded
and annulled.

   If  less  than all of the Bonds at the time outstanding
are  to be called for redemption, the particular Bonds  or
portions of Bonds to be redeemed shall be selected by  the
Trustee,  in such manner as the Trustee in its  discretion
may  deem  proper, in the principal amounts designated  to
the Trustee by the Company or otherwise as required by the
Indenture;  provided, however, that, if the Company  shall
have  offered  to purchase all Bonds then outstanding  and
less than all such Bonds have been tendered to the Company
for  such purchase, the Trustee, at the direction  of  the
Company, shall select for redemption all such Bonds  which
shall not have been so tendered.

  In the event any of the Bonds are called for redemption,
the  Trustee  shall  give  notice,  in  the  name  of  the
Pollution Control Corporation, of the redemption  of  such
Bonds.   Such notice shall be given by mailing a  copy  of
the  redemption notice by first-class mail at least thirty
(30)  days  prior  (except in the  case  of  a  redemption
pursuant  to clause (e) of the fourth preceding paragraph)
to  the  date  fixed for redemption to the owners  of  the
Bonds  to  be  redeemed  at the  addresses  shown  on  the
registration  books; provided, however, that failure  duly
to  give  such  notice by mailing, or any defect  therein,
shall  not affect the validity of any proceedings for  the
redemption of the Bonds as to which there shall be no such
failure or defect.

   With  respect to any notice of redemption of  Bonds  in
accordance  with the redemption provisions  lettered  (a),
(b)  or (c) above, unless, upon the giving of such notice,
such  Bonds  shall be deemed to have been paid within  the
meaning  of  the Indenture, such notice shall  state  that
such redemption, shall be conditional upon the receipt, by
the  Trustee on or prior to the opening of business on the
date fixed for such redemption of moneys sufficient to pay
the principal of and premium, if any, and interest on such
Bonds  to  be redeemed, and that if such moneys shall  not
have been so received said notice shall be of no force and
effect and the Pollution Control Corporation shall not  be
required  to  redeem such Bonds. In the  event  that  such
notice  of redemption contains such a condition  and  such
moneys  are not so received, the redemption shall  not  be
made  and  the  Trustee  shall within  a  reasonable  time
thereafter give notice, in the manner in which the  notice
of  redemption  was given, that such moneys  were  not  so
received.

   If a notice of redemption shall be unconditional, or if
the conditions of a conditional notice of redemption shall
have  been satisfied, then upon presentation and surrender
of  Bonds so called for redemption at the place or  places
of payment, such Bonds shall be redeemed.

   Any  Bonds and portions of Bonds which have  been  duly
selected  for redemption or deemed selected for redemption
and  which  are deemed to be paid in accordance  with  the
Indenture  shall cease to bear interest on  the  specified
redemption date and shall thereafter cease to be  entitled
to any lien, benefit or security under the Indenture.

   The  owner of this Bond shall have no right to  enforce
the provisions of the Indenture, or to institute action to
enforce the covenants therein, or to take any action  with
respect  to  any  default  under  the  Indenture,  or   to
institute,  appear  in  or  defend  any  suit   or   other
proceeding with respect thereto, except as provided in the
Indenture.

    With  certain  exceptions  as  provided  therein,  the
Indenture  and  the  Loan Agreement  may  be  modified  or
amended  only with the consent of the owners of a majority
in  aggregate  principal amount of all  Bonds  outstanding
under  the  Indenture  which would be  adversely  affected
thereby.

   Reference is hereby made to the Indenture and the  Loan
Agreement,  copies of which are on file with the  Trustee,
for  the  provisions, among others, with  respect  to  the
nature and extent of the rights, duties and obligations of
the   Pollution  Control  Corporation,  the  Company,  the
Trustee, the Remarketing Agent, the Tender Agent, the Bank
and  the  owners of the Bonds. The owner of this Bond,  by
the  acceptance  hereof,  is deemed  to  have  agreed  and
consented to the terms and provisions of the Indenture and
the Loan Agreement.

   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  within the meaning and with the effect expressed  in
the   Indenture,  and  the  entire  indebtedness  of   the
Pollution Control Corporation in respect thereof shall  be
satisfied  and  discharged, if there has been  irrevocably
deposited  with the Trustee, in trust, money in an  amount
which will be sufficient and/or Government Obligations (as
defined  in the Indenture), the principal of and  interest
on  which,  when  due, without regard to any  reinvestment
thereof,  will provide moneys which, together with  moneys
deposited with or held by the Trustee, will be sufficient,
to  pay when due the principal of and premium, if any, and
interest  on  this Bond or such portion of  the  principal
amount hereof when due.

   The  Pollution  Control Corporation, the  Trustee,  the
Registrar,  the Tender Agent, the Remarketing  Agent,  the
Paying  Agent, any authenticating agent and any  co-paying
agent  may  deem and treat the person in whose  name  this
Bond  is  registered as the absolute owner hereof for  all
purposes, whether or not this Bond is overdue, and neither
the Pollution Control Corporation, the Trustee, the Tender
Agent,  the  Remarketing Agent, the Paying Agent  nor  any
co-paying  agent shall be affected by any  notice  to  the
contrary.

   It  is hereby certified, recited and declared that  all
acts,  conditions and things required by the  Constitution
and  laws  of  the  State of Arizona  to  exist,  to  have
happened and to have been performed, precedent to  and  in
the  execution  and  delivery of  the  Indenture  and  the
issuance  of this Bond, do exist, have happened  and  have
been performed in regular and due form as required by law.

Indenture shall be deemed to be a covenant or agreement of
any  official, officer, agent or employee of the Pollution
Control  Corporation  in  his  individual  capacity,   and
neither  the  members  of the Board of  Directors  of  the
Pollution  Control Corporation, nor any official executing
this  Bond, shall be liable personally on this Bond or  be
subject  to  any  personal liability or accountability  by
reason of the issuance or sale of this Bond.

   This Bond shall not be entitled to any right or benefit
under the Indenture, or be valid or become obligatory  for
any purpose, until this Bond shall have been authenticated
by  the  execution  by the Trustee, or  its  successor  as
Trustee,  or  an  authenticating  agent  thereof,  of  the
certificate of authentication inscribed hereon.

    IN WITNESS WHEREOF, Coconino County, Arizona Pollution

proceedings to terminate a Plan by the PBGC or the
appointment by the PBGC or a court of competent
jurisdiction of a trustee to administer a Plan, or (v) any

No. 87, based upon the actuarial assumptions used by the
plan's actuary in the most recent annual valuation of the
Plan.

          I.02.       Computation of Time Periods.  In this
Agreement, in the computation of a period of time from a
specified date to a later specified date, the word "from"
means "from and including" and the words "to" and "until"
each means "to but excluding".

          I.03.       Accounting Terms.  All accounting terms not
specifically defined herein shall be construed in
accordance with generally accepted United States accounting
principles consistent (except as otherwise stated herein)
with those applied in the preparation of the December 31,
1995 financial statements referred to in Section 4.01(f).

          I.04.       Internal References.  The words "herein",
"hereof" and "hereunder" and words of similar import, when

                            II.
         AMOUNT AND TERMS OF THE LETTER OF CREDIT

          II.01.      The Letter of Credit.  The Bank agrees, on the
terms and conditions hereinafter set forth, to issue the
Letter of Credit to the Trustee on any Business Day during
the period from the date hereof to and including May 1,
1996 (the "Commitment Termination Date").

          II.02.      Issuing the Letter of Credit.  The Letter of
Credit shall be issued on at least three Business Days'
notice from the Company to the Bank specifying the Business
Day of issuance thereof.  On such Business Day specified by
the Company in such notice and upon fulfillment of the
applicable conditions precedent set forth in Article III,
the Bank will issue the Letter of Credit to the Trustee.

          II.03.      Commissions and Fees.  (a) The Company hereby
agrees to pay to the Bank a letter of credit fee on the
Stated Amount from the date the Letter of Credit is issued
until the Cancellation Date, at the Applicable L/C Rate as
adjusted from time to time, which letter of credit fee
shall be payable quarterly in arrears on the last Business
Day of each June, September, December and March commencing
on June 28, 1996, and on the Cancellation Date.

          (a)       The Company hereby agrees to pay to the Bank a
transfer commission of $2,000 upon each transfer of the
Letter of Credit in accordance with its terms.

          (b)       The Company agrees to pay to the Bank the fees
and other amounts set forth in the Fee Letter on the dates
set forth therein.

          II.04.      Reimbursement On Demand.  Except as otherwise
specified in Section 2.05 (and provided the conditions
precedent specified therein shall have been fulfilled),
each amount paid by the Bank under the Letter of Credit
(including, without limitation, amounts in respect of any
reinstatement of the Interest Component (as defined in the
Letter of Credit) at the election of the Bank
notwithstanding any failure by the Company to reimburse the
Bank for any previous drawing to pay interest on the Bonds)
shall constitute a demand loan made by the Bank to the
Company on the date of such payment by the Bank under the
Letter of Credit.  The Company agrees to pay each such
demand loan on the date of its making.  Any such demand
loan (or any portion thereof) not so paid on such date
shall bear interest, payable on demand, from the date of
making of such demand loan until payment in full, at a
fluctuating interest rate per annum equal to the Default
Rate.

          II.05.      Advances and Interest.  (a)  If the Bank shall
make any payment under the Letter of Credit in response to
a Tender Drawing submitted thereunder pursuant to Section
2.02(g) of the Indenture and to a Redemption/Mandatory
Purchase Drawing pursuant to Sections 2.02(h)(i) and (ii)
of the Indenture, such payment shall, notwithstanding
Section 2.04, constitute an advance made by the Bank to the
Company on the date and in the amount of such payment (each
such advance being an "Advance").  The Company shall pay
interest on the unpaid principal amount of each Advance
quarterly in arrears on the last Business Day of March,
June, September and December of each calendar year.  Each
Advance shall bear interest (i) from the date of the
incurrence thereof until the earlier of (A) the date upon
which such Advance is paid in full and (B) the date which
is 90 days after the date of the incurrence thereof, at the
Alternate Base Rate and (ii) from and after the 90th day
from the date of incurrence thereof until the date upon
which such Advance is paid in full, at the Alternate Base
Rate plus 1%.  Notwithstanding any other provision to the
contrary herein, each Advance shall be due and payable by
the Company to the Bank on the Cancellation Date.

          (a)       Notwithstanding any provision to the contrary
herein, the Company shall pay interest on all past-due
amounts of principal and (to the fullest extent permitted
by law) interest, costs, fees and expenses hereunder, from
the date when such amounts became due until paid in full,
payable on demand, at the Default Rate in effect from time
to time.

     II.06.      Prepayments.  (a)  The Company may, upon at
least two Business Days' notice to the Bank, prepay the
outstanding amount of any Advance in whole or in part with
accrued interest to the date of such prepayment on the
amount prepaid.

          (a)       Prior to or simultaneously with the resale of all
of the Bonds purchased with the proceeds of a Tender
Drawing under the Letter of Credit, the Company shall
prepay or cause to be prepaid in full the then outstanding
principal amount (pursuant to Section 2.04) or Advance
arising pursuant to such Tender Drawing, together with all
interest thereon to the date of such prepayment.  If less
than all of such Bonds are resold, then prior to or
simultaneously with such resale the Company shall prepay or
cause to be prepaid a portion (as specified below) of the
then outstanding principal amount (pursuant to Section
2.04) or Advance arising pursuant to such Tender Drawing,
together with all interest thereon to the date of such
prepayment.  The portion of such principal amount or such
Advance to be prepaid shall be determined by multiplying
such principal amount or such Advance by a fraction, the
numerator of which shall be the face amount of the Bonds
resold and the denominator of which shall be the face
amount of all of the Bonds purchased with the proceeds of
the relevant Tender Drawing.

          II.07.      Increased Costs.  If either (i) the
introduction of or any change (including, without
limitation, any change by way of imposition or increase of
reserve requirements other than those referred to in the
definition of "Domestic Reserve Percentage" in or in the
interpretation of any law or regulation or (ii) the
compliance by the Bank with any guideline or request from
any central bank or other governmental authority (whether
or not having the force of law), shall either (A) impose,
modify or deem applicable any reserve, special deposit or
similar requirement against letters of credit issued by, or
assets held by, or deposits in or for the account of, the
Bank or participated in by any Participant or (B) impose on
the Bank any other condition regarding this Agreement, the
Letter of Credit, any amount outstanding hereunder or any
Advance, and the result of any event referred to in clause
(A) or (B), above, shall be to increase the cost to the
Bank or any Participant of issuing or maintaining the
Letter of Credit (or its participation therein) or agreeing
to make or making, funding or maintaining any Advance by an
amount which the Bank or any such Participant deems to be
material, then, upon demand by the Bank, the Company shall
pay to the Bank (for its own account or for the account of
such Participant, as the case may be, within 10 days of
receipt of such notice and from time to time as specified
by the Bank, all additional amounts which shall be
sufficient to compensate the Bank for such increased costs.
A certificate setting forth such increased costs incurred
by the Bank as a result of any event referred to in clause
(i) or (ii), above, submitted by the Bank to the Company,
shall constitute such demand and shall, in the absence of
manifest error, be conclusive and binding for all purposes.

          II.08.      Increased Capital.  If the Bank determines
(1) the adoption of any applicable law, rule or regulation
after the date hereof regarding capital adequacy, or any
change therein, or any change in the interpretation or
administration thereof by any court or administrative or
governmental authority charged with the interpretation or
administration thereof, or (2) compliance by the Bank with
any directive regarding capital adequacy of any such admini
strative or governmental authority, generally affects banks
issuing letters of credit or entering into agreements
similar to or of the same type as this Agreement and has or
would have the effect of reducing the rate of return on the
Bank's capital as a consequence of issuing or maintaining
the Letter of Credit to a level below that which the Bank
would have achieved but for such adoption, change or com
pliance (taking into consideration the Bank's policies with
respect to capital adequacy), then, upon demand by the
Bank, the Company shall immediately pay to the Bank, from
time to time as specified by the Bank, additional amounts
sufficient to compensate the Bank in the light of such
circumstances, to the extent that the Bank reasonably
determined such capital to be allocable to this Agreement
or the issuance or maintenance of the Letter of Credit.  In
determining such increased fee, the Bank may use reasonable
and customary averaging and attribution methods.  A
certificate as to such amounts submitted to the Company by
the Bank shall constitute such demand and shall, in the
absence of manifest error, be conclusive and binding for
all purposes.

          II.09.      Payments and Computations.  The Company shall
make each payment hereunder not later than 12:00 noon (Los
Angeles time) on the day when due in lawful money of the
United States of America to the Bank at its address
referred to in Section 7.02 in same day funds. Computations
of (i) the Alternate Base Rate, the Prime Rate and the
Default Rate shall be made by the Bank on the basis of a
year of 365/366 days, as the case may be, and the actual
number of days (including the first day but excluding the
last day) elapsed and (ii) the commissions and fees under
Section 2.03 shall be made by the Bank on the basis of a
year of 360 days and the actual number of days (including
the first day but excluding the last day) elapsed.
Paragraph definition changed to X.  1.
Starting paragraph ?.10.
I.01.
          II.010.     Non-Business Days.  Whenever any payment to be
made hereunder shall be stated to be due on a day which is
not a Business Day, such payment shall be made on the next
succeeding Business Day, and such extension of time shall
in such case be included in the computation of interest,
commission or fee, as the case may be.
II.011.
          II.011.     Extension of the Stated Termination Date;
Reduction of Stated Amount.  (a)  Unless the Letter of
Credit shall have expired in accordance with its terms, at
least 75 but not more than 120 days before each of the
first and second anniversary of the date of issuance of the
Letter of Credit, the Company may request the Bank in
writing (each such request being irrevocable) to extend for
one year the Stated Termination Date.  If the Company shall
make any such request, the Bank shall, no later than 30
days following the date on which the Bank shall have
received such request, notify the Company in writing (with
a copy of such notice to the Trustee) whether or not the
Bank consents, in its sole discretion, to such request and,
if the Bank does so consent, the conditions of such consent
(including conditions relating to legal documentation).  If
the Bank shall not so notify the Company, the Bank shall be
deemed not to have consented to such request.  Upon the
Bank's consenting to any such extension, the Company shall
cause the Trustee to surrender the Letter of Credit to the
Bank.  Simultaneously with such surrender, the Bank may at
its option either (a) return the Letter of Credit after
amendment thereof to reflect the extension of the scheduled
expiration date or (b) cancel the Letter of Credit and
issue to the Trustee, in substitution therefor, a
substitute irrevocable letter of credit in the form of
Exhibit A hereto, dated the date of such surrender,
reflecting the extension of the scheduled expiration date
but otherwise having terms substantially identical to the
Letter of Credit being so extended.

     (b)  The Company shall have the right at any time to
permanently reduce the Stated Amount of the Letter of
Credit in the amount of Bonds which have been defeased in
an amount equal to such principal amount plus the amount of
interest, calculated in accordance with the Letter of
Credit, with respect to such principal amount, upon
directing the Trustee to give written notice to the Bank
pursuant to Paragraph 4 of the Letter of Credit.

          II.012.     Evidence of Debt.  The Bank shall maintain, in
accordance with its usual practice, an account or accounts
evidencing the indebtedness of the Company resulting from
each drawing under the Letter of Credit and from each
Advance made from time to time hereunder and the amounts of
principal and interest payable and paid from time to time
hereunder.  In any dispute, legal action or proceeding in
respect of this Agreement, the entries made in such account
or accounts shall, in the absence of manifest error, be
conclusive evidence of the existence and amounts of the
obligations of the Company therein recorded.

          II.013.     Obligations Absolute.  The payment obligations
of the Company under this Agreement shall be unconditional
and irrevocable, and shall be paid strictly in accordance
with the terms of this Agreement under all circumstances,
including, without limitation, the following circumstances:

                    (i)       any lack of validity or enforceability of the
     Letter of Credit, the Bonds, the Indenture, the Loan
     Agreement, the Custodian Agreement, the Fee Letter, the
     Bond Purchase Agreement, the Remarketing Agreement, the
     Master Restructuring Agreement, the Supplement to Company
     Mortgage or the First Mortgage Bonds (collectively, the
     "Related Documents") or any other agreement or instrument
     relating thereto;

                    (ii)      any amendment or waiver of or any consent to or
     departure from all or any of the Related Documents;

                    (iii)          the existence of any claim, set-off, defense
     or other right which the Company may have at any time
     against the Trustee or any other beneficiary, or any
     transferee, of the Letter of Credit (or any Person for whom
     the Trustee, any such beneficiary or any such transferee
     may be acting), the Bank, or any other Person, whether in
     connection with this Agreement, the transactions
     contemplated herein or in the Related Documents, or any
     unrelated transaction;

                    (iv)      any statement or any other document presented
     under the Letter of Credit proving to be forged,
     fraudulent, invalid or insufficient in any respect or any
     statement therein being untrue or inaccurate in any
     respect, provided that acceptance of such statement or
     other document by the Bank does not result from the Bank's
     gross negligence or willful misconduct;

                    (v)       payment by the Bank under the Letter of Credit
     against presentation of a draft or certificate which does
     not comply with the terms of the Letter of Credit, provided
     that such payment shall not have constituted gross
     negligence or willful misconduct of the Bank; or

                    (vi)      any other circumstance or happening whatsoever,
     whether or not similar to any of the foregoing, provided
     that such other circumstance or happening shall not have
     been the result of gross negligence or willful misconduct
     of the Bank.

          II.014.     Taxes.  (a) All payments made by the Company
hereunder will be made without setoff, counterclaim or
other defense.  All such payments will be made free and
clear of, and without deduction or withholding for, any
present or future taxes, levies, imposts, duties, fees,
assessments or other charges of whatever nature now or
hereafter imposed by any jurisdiction or by any political
subdivision or taxing authority thereof or therein (but
excluding, except as provided below, any tax imposed on or
measured by the net income of the Bank pursuant to the laws
of the jurisdiction (or any political subdivision or taxing
authority thereof or therein) in which the principal office
or lending office of the Bank is located) and all interest,
penalties or similar liabilities with respect thereto
(collectively, "Taxes").  If the Company shall be required
by law to deduct any Taxes from or in respect of any sum
payable hereunder or under the Fee Letter, (i) the sum
payable shall be increased as necessary so that after
making all required deductions (including deductions
applicable to additional sums payable under this Section
2.14) such Bank receives an amount equal to the sum it
would have received had no such deductions been made, (ii)
the Company shall make all such required deductions and
shall pay the full amount deducted to the relevant taxing
authority in accordance with applicable law and (iii) the
Company will furnish to the Bank, within 45 days after the
date the payment of any Taxes is due, certified copies of
tax receipts evidencing such payment by the Company.  If
any amounts are payable in respect of Taxes pursuant to the
preceding sentence, the Company agrees to reimburse the
Bank, upon the written request of the Bank for taxes
imposed on or measured by the net income of the Bank
pursuant to the laws of the jurisdiction (or any political
subdivision or taxing authority thereof or therein) in
which the principal office or lending office of the Bank is
located and for any withholding of taxes as the Bank shall
determine are payable by, or withheld from, the Bank in
respect of such amounts so paid to or on behalf of the Bank
pursuant to the preceding sentence and in respect of any
amount paid to or on behalf of the Bank pursuant to this
sentence.  The Company will indemnify and hold harmless the
Bank, and reimburse the Bank upon its written request, for
the amount of any Taxes so levied or imposed and paid by
the Bank.  The Bank shall use reasonable efforts (subject
to overall policy considerations of the Bank) to avoid or
minimize, as the case may be, the payment by the Company of
any additional sums under this Section 2.14 or the
subjection of any payment by the Company to Taxes
pertaining to the Bank, provided that such avoidance or
minimization is made on such terms that the Bank suffers no
economic, legal or regulatory disadvantage.

          (b)  The Bank represents and warrants to the
Company that either (1) as of the date of this Agreement it
is entitled to the benefits of an income tax treaty with
the United States which provides for an exemption from
United States withholding tax on interest and other
payments to be made by the Company to the Bank pursuant to
the terms of this Agreement; or (2) all interest and other
payments to be made by the Company to the Bank pursuant to
the terms of this Agreement will be effectively connected
with the conduct by the Bank of a trade or business within
the United States (within the meaning of Section 882 of the
Code).  Prior to the date of issuance of the Letter of
Credit and, to the extent legally entitled to do so,
thereafter upon the request of the Company, the Bank agrees
to furnish to the Company two copies of either U.S.
Internal Revenue Service Form 4224 or U.S. Internal Revenue
Service Form 1001 (wherein the Bank claims entitlement to
complete exemption from U.S. federal withholding tax on all
interest and other payments hereunder).  In the event the
Bank fails to provide an accurate Form 4224 or Form 1001
required by this paragraph and which it is legally entitled
to provide, the Company shall not be required to pay any
additional amounts with respect to U.S. Federal income
taxes to such Bank pursuant to this paragraph.
Notwithstanding any other provisions of this Agreement and
except in the event of a change in applicable law, the
representations, warranties and obligations of the Bank set
forth in this paragraph in respect of any interest in this
Agreement or the Letter of Credit shall survive until the
assignment, sale, payment or other disposition of such
interest or the Letter of Credit.

VII.                  MISCELLANEOUS

          VII.01.     Amendments, Etc.  No amendment or waiver of any

          VII.03.     No Waiver; Remedies.  No failure on the part of
the Bank to exercise, and no delay in exercising, any right

any other right.  The remedies herein provided are
cumulative and not exclusive of any remedies provided by
law.

          VII.04.     Right of Set-off.  (a) Upon the occurrence and
during the continuance of any Event of Default, the Bank is
hereby authorized at any time and from time to time, to the
fullest extent permitted by law, to set off and apply any

provisional or final) at any time held and other
indebtedness at any time owing by the Bank to or for the
credit or the account of the Company against any and all of
the obligations of the Company now or hereafter existing
under this Agreement, irrespective of whether or not the
Bank shall have made any demand hereunder and although such
obligations may be contingent or unmatured.  The rights of
the Bank under this Section are in addition to other rights
and remedies (including, without limitation, other rights
of set-off) which the Bank may have.

     (b)  The Bank agrees promptly to notify the Company

          VII.05.     Indemnification.  The Company hereby
indemnifies and holds the Bank, its officers, directors,
employees and agents harmless from and against any and all
claims, damages, losses, liabilities, costs and expenses
which the Bank may incur or which may be claimed against
the Bank, its officers, directors, employees and agents by
any Person:

               (a)   by reason of or in connection with the execution,
     delivery or performance of, or the sale or resale of, the
     Bonds including those resulting from any misstatement in or
     omission from any official statement or other offering
     document or supplement thereto relating to the Bonds
     (except any misstatement in or omission resulting from
     information furnished in writing by the Bank expressly for
     inclusion in such offering documents), the Indenture, the
     Loan Agreement, any other Related Document or any
     transaction contemplated thereby, other than as specified
     in subsection (b) below; or

               (b)   by reason of or in connection with the execution
     and delivery, transfer or use of the proceeds of, or
     payment or failure to make payment under, the Letter of
     Credit; provided, however, that the Company shall not be
     required to indemnify the Bank pursuant to this Section
     7.05(b) for any claims, damages, losses, liabilities, costs
     or expenses to the extent caused by (i) the Bank's willful
     misconduct or gross negligence in determining whether
     documents presented under the Letter of Credit are genuine
     or comply with the terms of the Letter of Credit or (ii)
     the Bank's willful or grossly negligent failure to make
     lawful payment under the Letter of Credit after the
     presentation to it by the Trustee under the Indenture of a
     draft and certificate strictly complying with the terms and
     conditions of the Letter of Credit.

               (c)    The Company will also indemnify and hold harmless
     the Bank from and against all losses and reasonable costs
     or expenses which the Bank may incur by reason of either
     (i) any failure of the Remarketing Agent to pay when due
     the purchase price of any Bond for which the Remarketing
     Agent has given the notice referred to in alternate 2 of
     paragraph (1) of Exhibit 4 of the Letter of Credit and/or
     (ii) any failure by the Trustee promptly to turn over to
     the Bank in accordance with the provisions of the Indenture
     the proceeds from the sale of any such Bond received from
     the Remarketing Agent.  The Company shall pay to the Bank
     any such amounts not paid by the Remarketing Agent or the
     Trustee, as the case may be, upon demand.

Nothing in this Section 7.05 is intended to limit the
Company's obligations contained in Article II.  Without
prejudice to the survival of any other obligation of the
Company hereunder, the indemnities and obligations of the
Company contained in this Section 7.05 shall survive the
payment in full of amounts payable pursuant to Article II
and the termination of the Letter of Credit.

          VII.06.  Bank Not Liable.  (a)  The Company assumes all
risks of the acts or omissions of the Trustee, the
Remarketing Agent and any beneficiary or transferee of the
Letter of Credit with respect to its use of the Letter of
Credit.  Neither the Bank nor any of its officers,
directors, employees or agents shall be liable or
responsible for:  (a) the use which may be made of the
Letter of Credit or any acts or omissions of the Trustee
and any other beneficiary or transferee in connection
therewith; (b) the validity, sufficiency or genuineness of
documents, or of any endorsement thereon, even if such
documents should prove to be in any or all respects
invalid, insufficient, fraudulent or forged; (c) payment by
the Bank against presentation of documents which do not
comply with the terms of the Letter of Credit, including
failure of any documents to bear any reference or adequate
reference to the Letter of Credit; or (d) any other
circumstances whatsoever in making or failing to make
payment under the Letter of Credit, except that the Company
shall have a claim against the Bank, and the Bank shall be
liable to the Company, to the extent of any direct, as
opposed to consequential, damages suffered by the Company
which the Company proves were caused by (i) the Bank's
willful misconduct or gross negligence in determining
whether documents presented under the Letter of Credit are
genuine or comply with the terms of the Letter of Credit or
(ii) the Bank's willful or grossly negligent failure to
make lawful payment under the Letter of Credit after the
presentation to it by the Trustee under the Indenture of a
draft and certificate strictly complying with the terms and
conditions of the Letter of Credit.  In furtherance and not
in limitation of the foregoing, the Bank may accept
original or facsimile (including telecopy) sight drafts and
accompanying certificates presented under the Letter of
Credit that appear on their face to be in order, without
responsibility for further investigation, regardless of any
notice or information to the contrary.

          (b)  The Bank shall not have any liability to the
Company, and the obligations of the Company under this
Agreement shall not be affected by (1) the form,
sufficiency, correctness, validity, genuineness and legal
effect of any drafts, demands and other documents,
instruments and other papers relating thereto, (2) the good
faith and acts of any Person, (3) the existence, form,
sufficiency and breach of contracts of any nature
whatsoever, including the Related Documents, (4) the
solvency, standing and responsibility of any Person, (5)
any delay in giving or failure to give any notice, demand
or protest, (6) failure of any Person to comply with the
terms of the Letter of Credit, (7) errors, omissions or
delays in or nondelivery of any message, however sent, and
(8) any other error, neglect or omission, except as
provided in the last sentence of paragraph (a) of this
Section.

          (c)  The Bank shall not have any liability to the
Company for, and the Company waives any right to object to,
payment made under the Letter of Credit against a demand
varying in punctuation, capitalization, spelling or similar
matters of form.  The determination whether a demand has
been made before the expiration of the Letter of Credit and
whether a demand is in proper and sufficient form for
compliance with the Letter of Credit shall be made by the
Bank in its sole discretion, which determination shall be
conclusive and binding upon the Company except as otherwise
expressly provided in this Agreement.

          VII.07.     Costs, Expenses and Taxes.  The Company agrees
to pay on demand all costs and expenses in connection with
the preparation, execution, delivery, filing, recording,
and administration (including any amendment or waiver) of
this Agreement and any other documents which may be
delivered in connection with this Agreement, including,
without limitation, the reasonable fees and out-of-pocket
expenses of counsel for the Bank, and local counsel who may
be retained by said counsel, with respect thereto and with
respect to advising the Bank as to its rights and
responsibilities under this Agreement and such other
documents which may be delivered in connection with this
Agreement and all costs and expenses (including counsel
fees and expenses) in connection with (i) the enforcement

otherwise) of this Agreement and such other documents which
may be delivered in connection with this Agreement or
(ii) any action or proceeding relating to a court order,
injunction, or other process or decree restraining or
seeking to restrain the Bank from paying any amount under
the Letter of Credit.  In addition, the Company shall pay
any and all stamp and other taxes and fees payable or
determined to be payable in connection with the execution,
delivery, filing and recording of this Agreement or the
Letter of Credit or any of such other documents, and agrees
to save the Bank harmless from and against any and all
liabilities with respect to or resulting from any delay in
paying or omission to pay such taxes and fees.

          VII.08.     Binding Effect.  This Agreement shall become
effective when it shall have been executed and delivered by
the Company and the Bank and thereafter shall be binding
upon and inure to the benefit of the Company and the Bank
and their respective successors and assigns, except that
the Company shall not have the right to assign its rights
hereunder or any interest herein without the prior written
consent of the Bank.

          VII.09.   Severability.  Any provision of this Agreement
which is prohibited, unenforceable or not authorized in any
jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition, unenforceability or
non-authorization without invalidating the remaining
provisions hereof or affecting the validity, enforceability
or legality of such provision in any other jurisdiction.

          VII.010.    Governing Law; Submission to Jurisdiction; etc.
This Agreement shall be governed by, and construed in
accordance with, the laws of the State of New York.  Any
action or proceeding arising out of or relating to this
Agreement or the Letter of Credit shall be heard and
determined in an appropriate state or federal court in the
State of New York.  The Company irrevocably waives, to the
fullest extent permitted by law, any objection which it may
now or hereafter have to the laying of venue of any such
suit, action or proceeding brought in such courts and any
claim that any such suit, action or proceeding has been
brought in an inconvenient forum.  The Company also irrevo
cably consents to the service of any and all process in any
such suit, action or proceeding by mailing of copies of
such process to the Company at its address provided in
Section 7.02.  The Company agrees that a final judgment not
stayed in any such action or proceeding shall be conclusive
and may be enforced in other jurisdictions by suit on the
judgment or in any other manner provided by law.  All
mailings under this Section 7.10 shall be by certified
mail, return receipt requested.  Nothing in this Section
7.10 shall affect the right of the Bank to serve legal
process in any other manner permitted by law or affect the
right of the Bank to bring any suit, action or proceeding
against the Company or its property in the courts of any
other jurisdiction.

          VII.011.    Headings.  Section headings in this Agreement
are included herein for convenience of reference only and

purpose.

          VII.012.    Counterparts.  This Agreement may be executed
by the parties hereto in separate counterparts, each of
which when so executed and delivered shall be an original,
but all such counterparts shall together constitute but one

          VII.013.    Waiver of Jury Trial.  EACH PARTY HEREBY
WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT
IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION
DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN
CONNECTION WITH THIS AGREEMENT.  THE PARTIES HERETO (a)
CERTIFY THAT NO REPRESENTATIVE OR ATTORNEY OF ANY OTHER
PERSON HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH
OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO
ENFORCE THE FOREGOING WAIVER, AND (b) ACKNOWLEDGE THAT THEY
HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE
TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT AND THE OTHER
RELATED DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL
WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION.

          VII.014.       Assignment and Participation.  (a) The Bank
may with the consent of the Company (which consent may not
be unreasonably withheld) assign to one or more financial
institutions all, or a proportional part of all, of its
rights and obligations under this Agreement, as such
assignee shall assume such rights and obligations.  Upon
any such assignment the assignee shall become a party to
this Agreement, shall be a "Bank" hereunder and shall be
entitled to all of the rights and benefits hereunder
(including, without limitation, the rights set forth in
Sections 2.07, 2.08, 2.14, 7.04, 7.05 and 7.07).

Company (which consent may not be unreasonably withheld),
sell participations to one or more banks or other financial
institutions (each a "Participant") in all or a portion of
its rights and obligations under this Agreement; provided,
however, (1) the Bank's obligations under this Agreement
shall remain unchanged, (ii) the Bank shall remain solely
responsible to the Company for the performance of such
obligations, (iii) except as expressly set forth herein,
any such Participant shall be entitled to the benefit of
the cost and fee protection and indemnification provisions

to the same extent as if the Participant were the Bank
hereunder, and (iv) the Trustee and the Issuer shall
continue to deal solely and directly with the Bank in
connection with the Bank's rights and obligations under
this Agreement and the Related Documents and the Bank shall
retain the sole right to approve any amendment,

          (c)  The Bank may disclose to any assignee or
Participant or proposed assignee or Participant any
information that the Company has delivered or is required

other Related Documents.

          VII.015.       Beneficiaries.  This Agreement is made

assigns, and the Company, its successors and assigns and no
other Person shall have any right, benefit or interest

                [Environmental Disclosure]

                                                 SCHEDULE 4.01(v)
                                                                 
                                                                 
                                                                 
(2)(B).    The  Company  received  a  letter  requesting  certain
information  pursuant to CERCLA Section 104 on  March  17,  1994
from  the  Arizona Dept. of Environmental Quality  (ADEQ).   This
request  dealt with a parcel that had been owned by the Company's
predecessor,  Tucson Gas & Electric (TG&E), from  1974  to  1984.
This  parcel, and other nearby non-Company parcels, had  received
some  dumping  of processed aluminum airplane parts ("dross")  in
the  late  1960's.  ADEQ had inspected the property in  1987  and
issued  a  report in 1988, with no other activity apparent  until
the ADEQ request letter of 1994.
           TG&E  conducted  no  activities  on  this  undeveloped
3)(A).    The Company is subject to a Consent Judgment with  the
Arizona Dept. of Environmental Quality (ADEQ) dated September 12,
1995,  concerning the Springerville Generating Station  (SGS)  in
Apache County, Arizona.  No judgment of any actual violations was
entered as part of this voluntary order, which centered on  tests
and  inspections  conducted  in July 1993;  rather,  the  Company
agreed to perform quarterly (rather than annual) particulate  air
quality  tests  on SGS Unit 2 for a period of one  year,  and  to
submit written plans for 1) additional particulate reductions  at
SGS, and 2) providing for backup ambient monitors in the event of
equipment failure.
           Both  written  plans were duly submitted  to  ADEQ  on
October 12, 1995, and two of the four quarters' testing have been
successfully  completed to date.  After two more quarterly  tests
are  completed,  the  Company may apply to  the  Maricopa  County
Superior Court for an order terminating the agreement.


(5).       The Company is a generator of hazardous waste at  both
its   Irvington  and  Springerville  Generation  Stations.   Both
operations are registered with the Arizona Dept. of Environmental
Quality  as Small Quantity Generators, and neither site  has  any
outstanding  notices of violation for hazardous waste activities.
The   treatment,  storage,  and  disposal  of  these  wastes  are
conducted  off-site  by  other parties under  contract  with  the
Company.

          "Collateral" means each Pledged Bond, all
payments of principal and interest payable on Pledged
Bonds, all of the Company's rights to receive Pledged Bonds
and amounts payable thereon and all of the Company's right,
title and interest in and to Pledged Bonds and such

irrespective of whether the obligation to pay any such
amount is direct or indirect, absolute or contingent, joint

arises by operation of law or otherwise or is from time to
time reduced and thereafter reincurred.  To the extent any

such payment so rescinded, recovered, restored or avoided

                    SECURITY INTEREST

          IX.01.      Grant of Security Interest.  As security for
the due and punctual payment in full of each of the
Obligations, the Company hereby grants to the Bank a
continuing first lien on and security interest in the
Collateral.

          IX.02.      Interest Continuing and Absolute.  Until
payment in full of all the Obligations has been
indefeasibly made after the Cancellation Date, the Bank's
security interest in the Collateral hereunder shall
continue in full force and effect, and it and the Company's
obligations hereunder shall be effective irrespective of
any illegality, invalidity or unenforceability of the
Bonds, the Letter of Credit, the Reimbursement Agreement or
any other Related Document.

          IX.03.      Perfection.  The Company shall perfect the
security interest of the Bank in the Collateral (a) in the

on the day such Bond becomes a Pledged Bond and, in the
case of proceeds, immediately.

          X.01.       Representations and Warranties.  The Company
represents and warrants to the Bank and, so long as any of
the Obligations remains unpaid, shall be deemed
continuously to represent and warrant to the Bank and the
Custodian, as follows:

          (a)       At the time of delivery to the Bank or the
     Custodian of any Collateral, the Company will have good and
     marketable title to, and be the sole owner of, such

     filed and no security agreement with respect to any of the
     Collateral shall have been executed by the Company, other
     than with respect to such security interest in favor of the
     Bank.

          (b)       The Bank has a valid and perfected first priority
     security interest in the Collateral.

          (c)       The Collateral may be properly pledged hereunder.

          (d)       No consents or approvals of any Person are
     required for the assignment and transfer by the Company of
     any of the Collateral to the Bank hereunder, or the
     subsequent sale or transfer of the Collateral by the Bank
     pursuant to the terms hereof.

          (e)       This Agreement has been duly executed and
     delivered by the Company and constitutes a legal, valid and
     binding obligation of the Company, enforceable against the
     Company in accordance with its terms.


                             XI.

                        COVENANTS

          XI.01.      Protection of the Bank's Security Interest.
The Company shall defend its title to, and the Bank's
security interest in, the Collateral against all claims of
all other Persons, and shall keep the Collateral free from
all liens and encumbrances (other than the Bank's security
interest hereunder) and pay or cause to be paid promptly
when due all taxes, fees, assessments and other charges now
or hereafter imposed on or in respect of any of the
Collateral.

          XI.02.      Sale of Collateral.  The Company shall not,
without the prior written consent of the Bank, sell,
transfer or otherwise dispose of, or permit any other
Person to sell, transfer or otherwise dispose of, any of
the Collateral or any of the Company's interests therein,
except in accordance with the terms of this Agreement, the
Indenture and the Remarketing Agreement.  The receipt by
the Bank of all or any part of the proceeds of any sale,
transfer or other disposition of any of the Collateral,
except in accordance with the prior sentence, shall not be
deemed or construed to be a consent by the Bank to any such
sale, transfer or other disposition.

          XI.03.      Further Assurances.  The Company shall execute
and deliver to the Bank or the Custodian such assignments
and other documents and instruments, and shall take all
other action relating to the Collateral and the
preservation, protection or perfection of the Bank's
security interest therein, as the Bank may request, and the
Company shall not file or permit to be filed any financing
statement (or amendment or continuation statement) or
execute any security agreement with respect to any of the
Collateral unless it names the Bank as the only secured
party.  To the extent permitted by law, the Company hereby
appoints the Bank as its attorney-in-fact (without
requiring the Bank to act as such) to perform all acts that
the Bank deems appropriate to preserve, protect and perfect
its continuing security interest in the Collateral or to
preserve or protect the Collateral.


                             XII.

   REMEDIES UPON THE OCCURRENCE OF AN EVENT OF DEFAULT

          XII.01.     Default Remedies.  If an Event of Default under
the Reimbursement Agreement shall occur and be continuing,
the Bank shall be entitled to exercise any one or more (at
the Bank's discretion, at one or more times) of the
following remedies:

          (a)       The Bank shall have the right to receive the
     Collateral, if any, then held by the Custodian, the
     Remarketing Agent, the Trustee or any other Person,
     endorse, assign or deliver in its own name or the name of
     the Company any and all checks, drafts and other
     instruments for the payment of money relating to or
     constituting part of the Collateral, and cause the
     Collateral to be registered in the name of the Bank or its
     designee, and the Company hereby waives presentment,
     protest and notice of nonpayment of any instrument so
     endorsed.  In furtherance of the foregoing, the Company
     hereby irrevocably appoints the Bank, or any of its
     officers or designees, the Company's lawful
     attorney-in-fact (without requiring the Bank so to act),
     with power of substitution, in the name of the Company or
     in the name of the Bank (i) to endorse the name of the
     Company upon any of the Collateral, including proceeds, and
     to cause any of the Collateral to be registered in the name
     of the Bank or its designee; (ii) to demand, collect,
     receive payment of, receipt for and give discharges and
     releases of any of the Collateral; (iii) to commence and
     prosecute any and all actions or proceedings at law or in
     equity in any court to collect or otherwise realize on any
     of the Collateral to enforce any rights in respect thereof;
     (iv) to initiate, settle, compromise, compound, adjust or
     defend any actions, suits or proceedings relating or
     pertaining to any of the Collateral; and (v) to sell,
     transfer, assign, discount, negotiate or otherwise deal in
     all or any portion of the Collateral or the proceeds
     thereof and generally to perform all other acts necessary
     or desirable to realize on, and obtain the benefits of, the
     Collateral and otherwise to carry out the intention of this
     Agreement, as fully and effectively as though the Bank were
     the absolute owner thereof, and the Company hereby ratifies
     and confirms all that the Bank shall do by virtue of this
     appointment.  The Bank shall not, under any circumstances,
     have any liability for any error or omission made in the
     settlement, collection or payment or other disposition of
     any or all of the Collateral or of any instrument received
     in payment therefor.

          (b)       The Bank may sell or cause to be sold, in one or
     more sales, at such price as the Bank may deem adequate,
     and for cash or on credit or for future delivery, with or
     without assumption of any credit risk, all or any portion
     of the Collateral, at public or private sale, without
     demand of performance or notice of intention to sell or of
     time or place of sale (except such notice as may be
     required by applicable statute and cannot be waived), and
     the Bank may be the purchaser of all or any portion of the
     Collateral so sold; provided, however, that the Bank shall
     first give notice to the Trustee that an Event of Default
     has occurred and is continuing.  The purchaser(s) at any
     such sale shall thereafter hold the Collateral so sold
     absolutely, free from any claim or right whatsoever,
     including any equity of redemption, of the Company.  Any
     such demand, notice, claim, right or equity is hereby
     expressly waived and released by the Company.  Without
     limiting the foregoing, if any such notice of the time or
     place of sale is so required, the Company agrees that the
     Bank need not give more than ten days' notice of the time
     and place of any public sale or of the time after which a
     private sale or other intended disposition is to take place
     and that such notice is reasonable notification of such
     matters.  The Bank shall not, under any circumstances,
     incur any liability as a result of the sale of the
     Collateral or any part thereof at any sale conducted in
     accordance with the provisions of this Agreement.  The
     Company hereby waives any claims against the Bank arising
     by reason of the fact that the price at which the
     Collateral may have been sold at any private sale was less
     than the price which might have been obtained at a public
     sale or was less than the aggregate principal amount of the
     Pledged Bonds or the then total unpaid Obligations.

          (c)       The Company recognizes that the Bank may not deem
     it desirable to effect a public sale of any or all of the
     Pledged Bonds or otherwise but may deem it desirable to
     resort to one or more private sales thereof to a restricted
     group of purchasers who will be obliged to agree, among
     other things, to acquire such securities for their own
     account for investment and not with a view to the
     distribution or resale thereof.  The Bank shall be under no
     obligation to delay a sale of any of the Pledged Bonds for
     the period of time necessary to permit the Issuer to
     register them for public sale under the Securities Act of
     1933, as amended (the "Act"), or under applicable state
     securities laws, even should the Issuer agree to do so.

          (d)       The Company shall do or cause to be done all such
     other acts and things as may be deemed necessary or
     desirable by the Bank to make such sale or sales of any
     portion or all of the Pledged Bonds valid and binding and
     in compliance with all applicable laws, regulations,
     orders, writs, injunctions, decrees or awards of any and
     all courts, arbitrators or governmental instrumentalities,
     domestic or foreign, having jurisdiction over any such sale
     or sales, including registering such Bonds under the Act,
     or any state securities laws (to the extent necessary), all
     at the Company's expense.

          (e)       The Company acknowledges that a breach of any of
     the covenants contained in this Article 5 will cause
     irreparable injury to the Bank and that the Bank has no
     adequate remedy at law in respect of any such breach and,
     as a consequence, agrees that each and every covenant
     contained in this Article 5 shall be specifically
     enforceable against the Company, and the Company hereby
     waives and agrees not to assert any defenses against an
     action for specific performance of such covenants except
     for a defense that no Event of Default has occurred.

          XII.02.     Remedies Not Exclusive.  (a)  The remedies
provided for herein are cumulative and are not exclusive of
any other rights, powers, privileges or remedies provided
by law or under the Reimbursement Agreement, including,
without limitation, all rights and remedies of a secured
party under Article 9 of the Uniform Commercial Code as in
effect in the State of New York on the date of the exercise
of any such remedy.  The exercise by the Bank of any one or
more remedies under Section 5.1, above, shall not
constitute a waiver, or otherwise prohibit, the exercise by
the Bank of other remedies provided herein or by law at the
same or other times.

          (a)       The Bank shall not be required to exercise any
particular rights, powers, remedies or benefits hereunder
or under the Reimbursement Agreement or any Related
Document.  Without limiting the generality of the
foregoing, the Bank (i) shall be entitled to seek to
realize upon or enforce the Collateral in such order as it
may from time to time determine and without regard to
whether or not any other collateral or security for any of
the Obligations shall have been resorted to, and (ii) shall
not be required to exhaust or enforce any particular
portion of the Collateral before seeking to realize or
enforce upon any other portion thereof.


                             XIII.

       COLLECTIONS BY THE COMPANY AND APPLICATIONS
           OF PROCEEDS IN RESPECT OF COLLATERAL

          XIII.01.    Collections on Pledged Bonds by the Company.
(a)  If, while any of the Obligations are outstanding, the
Company becomes entitled to receive or receives any payment
in respect of any Pledged Bond, the Company shall accept
such payment as the Bank's agent, hold it in trust on
behalf of the Bank and deliver it forthwith to the Bank for
application to satisfaction of the Obligations then due and
payable.  All sums of money so paid in respect of any
payment of interest on, or any portion of purchase price
equal to the amount of accrued interest on, any Pledged
Bond which are received by the Company and paid to the Bank
shall be credited against the obligation of the Company to
pay interest to the Bank set forth in Sections 2.04 and
2.05 of the Reimbursement Agreement.  All sums of money so
paid in respect of any payment of principal of, or any
portion of purchase price equal to the principal amount of,
any Pledged Bond which are received by the Company and paid
to the Bank shall be credited against the obligation of the
Company to pay principal to the Bank set forth in Sections
2.04 and 2.05 of the Reimbursement Agreement.

          XIII.02.    Application of Proceeds.  All proceeds received
from the sale or other disposition of, or realization on or
with respect to, all or any part of the Collateral shall be
applied by the Bank, in such order as the Bank, in its sole
discretion, may determine to the payment of the costs and
expenses of such sale, disposition or realization,
including, without limitation, reasonable fees and expenses
of counsel for the Bank and all expenses, liabilities and
advances of the Bank in connection therewith, and to the
payment of the remaining Obligations.


                             XIV.

        RELEASE OF COLLATERAL; COMPANY'S LIABILITY
                      FOR DEFICIENCY

          XIV.01.     Release of Collateral.  If (a) the Company
prepays or causes to be prepaid any Advance pursuant to
Section 2.06 of the Reimbursement Agreement, (b) the
Remarketing Agent causes Pledged Bonds at the time held
hereunder to be sold, or (c) the Obligations are otherwise
satisfied, upon receipt of such prepayment or of the
proceeds of such sale or other satisfaction of the
Obligations, Pledged Bonds in an aggregate principal amount
equal to the prepayment so made, or the principal amount of
Pledged Bonds so sold, or the Obligations so satisfied,
shall be automatically released from the lien of this
Agreement and the Company or its designee shall be entitled
to have the released Bonds delivered to the Remarketing
Agent, the Company or such other Person as designated by
the Company in accordance with the terms of the Indenture;
provided, however, that before any delivery of such
released Bonds, the Trustee and the Custodian shall have
received notice from the Bank of the reinstatement of the
amounts so prepaid, sold or satisfied as available under
the Letter of Credit and such notice shall constitute
notice to the Custodian to release the Pledged Bonds to the
Trustee.

          XIV.02.     Company's Liability for Deficiency.  The
Company shall in any event remain liable for any deficiency
remaining unpaid after the application of the proceeds of
the Collateral to the satisfaction of the Obligations.


                             XV.

                         GENERAL

          XV.01.      Expenses.  The Company shall pay to the Bank
all expenses (including reasonable fees and expenses of
counsel) of, or incident to, any actual or attempted sale
or other disposition of, or any exchange, enforcement
(whether through negotiations, legal proceedings or
otherwise), collection, compromise or settlement of or with
respect to, all or any of the Collateral, by litigation or
otherwise.  The Company shall reimburse the Bank on demand
for all reasonable costs and expenses incurred in
connection with the negotiation, preparation, execution and
administration of this Agreement, including, without
limitation, any fees or expenses (including reasonable fees
and expenses of counsel to the Custodian) paid by the Bank
to the Custodian for its services in connection with this
Agreement.

          XV.02.      Notices.  All notices and other communications
provided for hereunder shall be in writing (including
telegraphic communication) and mailed, telecopied, telexed,
telegraphed or delivered to the parties to the telex or
telecopier number or address (as the case may be) specified
for the intended recipient on the signature page hereof, or
to such other number or address as such recipient may have
last specified by notice to the other party.  All such
notices and communications shall, when mailed, telecopied,
telexed or telegraphed, be effective when deposited in the
mails or sent by telecopy or telex or delivered to the
telegraph company, respectively, addressed as aforesaid.

          XV.03.      Remedies and Waivers.  No failure or delay on
the part of the Bank in exercising any right hereunder
shall operate as a waiver of, or impair, any such right.
No single or partial exercise of any such right shall
preclude any other or further exercise thereof or the
exercise of any other right.  No waiver of any such right
shall be effective unless given in writing.  No waiver of
any such right shall be deemed a waiver of any other right
hereunder.  The remedies herein provided are cumulative and
not exclusive of any remedies provided by law.

          XV.04.      Amendment.  No amendment or waiver of any
provision of this Agreement, nor consent to any departure
by the Company therefrom, shall in any event be effective
unless the same shall be in writing and signed by the
Custodian and the Bank, and then such waiver or consent
shall be effective only in the specific instance and for
the specific purpose for which given.

          XV.05.      Assignment.  (a)  This Agreement shall be
binding upon and inure to the benefit of the Custodian, the
Bank and the Company and their respective successors and
assigns; provided, however, that the Company may not assign
any of its rights or obligations under this Agreement
without the prior written consent of the Bank.

          (a)       If the Bank or the Custodian assigns or otherwise
transfers any of its rights and obligations hereunder, each
reference in this Agreement to the Bank or the Custodian,
as the case may be, shall be deemed to be a reference to
the Bank or the Custodian, as the case may be, and the
Person or Persons to which such rights and obligations were
assigned and transferred to the extent of their respective
interests.

          XV.06.      Governing Law.  This Agreement shall be
governed by, and construed and interpreted in accordance
with, the laws of the State of New York.

          XV.07.      Custodian Appointed Agent.  The Bank hereby
appoints the Custodian as its agent to receive and hold
Pledged Bonds constituting Collateral granted hereunder for
the Bank's account.  The Company acknowledges such
appointment and agrees with the Bank and the Custodian,
which by its execution of this Agreement accepts such
appointment, that, for so long as this Agreement shall
remain in full force and effect, all certificates or
instruments representing or evidencing the Pledged Bonds
shall be delivered to and held by the Custodian, as agent
for the Bank.

          XV.08.      Reasonable Care.  The Custodian shall be deemed
to have exercised reasonable care in the custody and
preservation of the Collateral in its possession if the
Collateral is accorded treatment substantially equal to
that which the Custodian accords its own property.  In
executing, delivering and performing under this Custodian
Agreement, the Custodian shall be entitled to all rights,
privileges and immunities afforded the Trustee under the
Indenture which are hereby incorporated by reference.

          XV.09.      Integration of Terms.  This Agreement contains
the entire agreement between the parties relating to the
subject matter hereof and supersedes all oral statements
and prior writings with respect thereto.

          XV.010.     Counterparts.  This Agreement may be executed
in counterparts, and such counterparts taken together shall
be deemed to constitute one and the same agreement.

          XV.011.     Severability.  Any provision of this Agreement
which is prohibited or unenforceable in any jurisdiction
shall, as to such jurisdiction, be ineffective to the
extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof or affecting
the validity or enforceability of such provision in any
other jurisdiction.

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

                                       Letter of Credit]

SOCIETE GENERALE, LOS ANGELES BRANCH
2029 Century Park East
Suite 2900
Los Angeles, California  90067


                   Nevada Power Company


Ladies and Gentlemen:

     I am Vice President and General Counsel of Tucson
Electric Power Company, an Arizona corporation (the
"Company"), and have acted as such in connection with:

     (a)    the Letter of Credit and Reimbursement Agreement,
dated as of May 1, 1996 (the "Reimbursement Agreement"),
between the Company and Societe Generale, Los Angeles
Branch (the "Bank");
(b)
     (b)    the Thirty-Second Supplemental Indenture, dated as
of May 1, 1996 (the "First Mortgage Supplement"), from the
Company to The Chase Manhattan Bank (National Association),
as trustee (the "First Mortgage Trustee"), creating a
series of First Mortgage Bonds, Pollution Control Series J
(the "First Mortgage Bonds"), being a supplement to the
Indenture, dated as of April 1, 1941 (the "Original First
Mortgage"), from the Company to the First Mortgage Trustee;

     (c)    the Bond Delivery Agreement, dated as of May 1,
1996, from the Company to the Bank relating to the First
Mortgage Bonds; and

     (d)    the Custodian Agreement, dated as of May 1, 1996,
from the Company to the Bank.


     The documents referred to above (other than the
Original First Mortgage) are herein collectively referred
to as the "Financing Documents."  The Original First
Mortgage, as amended and supplemented by all indentures
supplemental thereto including the First Mortgage
Supplement, is hereinafter referred to as the "First
Mortgage."

     In so acting I have reviewed all corporate proceedings
of the Company in connection with the authorization,
execution and delivery of the First Mortgage and the
Financing Documents and the authorization, execution and
issuance of the First Mortgage Bonds.  I have also examined
such other documents and satisfied myself as to such other
matters as I have deemed necessary as a basis for the
opinions set forth below.  I have relied as to various
questions of fact upon the representations and warranties
of the Company contained in the Financing Documents, and in
the certificates of public officials and officers of the
Company delivered thereunder and have further relied upon
certificates of the First Mortgage Trustee as to the
authentication of the First Mortgage Bonds.

     Based upon and subject to the foregoing, and subject
also to the qualifications hereinafter set forth, I am of
the opinion that:

     XVI.      The Company (a) is duly organized, validly
existing and in good standing under the laws of the State
of Arizona, (b) has the corporate power and authority to
own and operate its property, to lease the property it
operates as lessee and to conduct the business in which it
is currently engaged, and (c) is duly qualified as a
foreign corporation and in good standing under the laws of
each jurisdiction where its ownership, lease or operation
of property or the conduct of its business requires such
qualification and (d) is in compliance with all laws,
treaties, rules or regulations applicable to or binding
upon it or any of its property or to which it or its
property is subject except to the extent, in each of (c)
and (d), that the failure to comply therewith would not, in
the aggregate, have a material adverse effect on the
business or operations of the Company.

     XVII.          The Company has the corporate power and
authority to execute, deliver and perform the Financing
Documents and to incur indebtedness thereunder and to issue
and deliver the First Mortgage Bonds and has taken all
necessary corporate action to authorize the execution,
delivery and performance of the Financing Documents and to
incur indebtedness thereunder and issue and deliver the
First Mortgage Bonds.

     XVIII.         The First Mortgage and the Financing
Documents have been duly and validly executed and delivered
on behalf of the Company and constitute legal, valid and
binding obligations of the Company, enforceable against it
in accordance with their respective terms except that
certain of the remedial provisions of the First Mortgage
may be limited by the law of the state wherein the
mortgaged property is located (however, such law does not,
in my opinion, make the remedies afforded by the First
Mortgage inadequate for the practical realization of the
benefits thereof) and except as enforceability may be
limited by applicable bankruptcy, insolvency,
reorganization, moratorium or other similar laws affecting
the enforcement of mortgagees' and other creditors' rights
generally and by general equitable principles (whether
enforcement is sought by proceedings in equity or at law)
and subject to any principles of public policy limiting the
right to enforce indemnification or contribution provisions
contained in the Financing Documents with respect to
liabilities under federal or state securities laws.

     XIX.      The First Mortgage Bonds have been duly and
validly issued, executed and delivered by the Company and
authenticated by the First Mortgage Trustee and are legal,
valid and binding obligations of the Company enforceable in
accordance with their terms (subject to the exceptions
referred to in paragraph 3 above) and are entitled to the
security and benefits of the First Mortgage.

     XX.       No consent or authorization of, filing with or
other act by or in respect of, the federal government, any
state, county, city or other political subdivision or
agency thereof or any entity exercising executive,
legislative, judicial, regulatory or administrative
functions pertaining thereto (collectively, a "Governmental
Authority") or any other person is required in connection
with the incurrence of indebtedness by the Company under
the Reimbursement Agreement or the issuance and delivery by
the Company of the First Mortgage Bonds or the mortgaging
of the Company's properties as security for the First
Mortgage Bonds or the execution, delivery or performance by
the Company or the enforceability against the Company of
the First Mortgage, the Financing Documents or the First
Mortgage Bonds except the Opinion and Order, dated
April 24, 1996, of the ACC relating thereto which has been
obtained and which is, to the best of our knowledge, in
full force and effect; provided, however, that I express no
opinion as to compliance with the securities or "blue sky"
laws of any jurisdiction.

     XXI.      The execution, delivery and performance by the
Company of the First Mortgage, or the Financing Documents,
the incurrence of indebtedness thereunder and the issuance
and delivery of the First Mortgage Bonds will not violate
any law, treaty, rule or regulation applicable to or
binding upon the Company or any of its property or to which
the Company or any of its property is subject or any
material contractual obligation of the Company and will not
result in, or require, the creation or imposition of any
lien or other encumbrance on any of its properties or
revenues pursuant to any such law, treaty, rule or
regulation or any such material contractual obligation of
the Company other than as contemplated by the First
Mortgage and the Financing Documents.

     XXII.          No litigation, investigation or proceeding
of or before any arbitrator or Governmental Authority is
pending or, to the best of my knowledge, threatened by or
against the Company or against any of its properties or
revenues (a) with respect to the Financing Documents, the
First Mortgage, the First Mortgage Bonds or any of the
transactions contemplated thereby or (b) which would have a
material adverse effect on the business or operations of
the Company other than such litigations, proceedings and
investigations as are disclosed in the Company's Annual
Report on Form 10-K for the year-ended December 31, 1995

P.C., of Tucson, Arizona.  As a member of the Bar of the
State of Arizona, I do not hold myself out as an expert on

of title and the lien of the First Mortgage and the filing
and recordation of the First Mortgage in the State of New
Mexico and conformity to New Mexico law, and as to all
other matters governed by New Mexico law, I have relied,
with your consent, upon the opinion of even date herewith

P.A., of Albuquerque, New Mexico.  As to matters governed
by New York law, the Securities Act of 1933, as amended,
the Public Utility Holding Company Act of 1935, as amended,
the Federal Power Act, as amended, or the Investment

involving technical compliance with the conditions set
forth in the First Mortgage precedent to the issuance of
the First Mortgage Bonds (insofar as such matters are
governed by the Trust Indenture Act of 1939, as amended), I
have relied, with your consent, upon the opinion of even
date herewith rendered to you by Reid & Priest LLP of New
York, New York.

     Reid & Priest LLP, Dickerman & Marvin, P.C. and Rodey,

                                                  EXHIBIT D



      [LETTERHEAD OF SPECIAL COUNSEL TO THE COMPANY]


                                      [Dates of Issuance of
                                          Letter of Credit]


SOCIETE GENERALE, LOS ANGELES BRANCH
2029 Century Park East
Suite 2900
Los Angeles, California  90067


              Tucson Electric Power Company


Ladies and Gentlemen:


     We are counsel to Tucson Electric Power Company, an
Arizona corporation (the "Company"), and have acted as such
in connection with:

     (a)    the Letter of Credit and Reimbursement Agreement,
dated as of May 1, 1996 (the "Reimbursement Agreement"),
between the Company and Societe Generale, Los Angeles
Branch (the "Bank");
(b)
     (b)    the Thirty-Second Supplemental Indenture, dated as
of May 1, 1996 (the "First Mortgage Supplement"), from the
Company to The Chase Manhattan Bank (National Association),
as trustee (the "First Mortgage Trustee"), creating a
series of First Mortgage Bonds, Pollution Control Series J
(the "First Mortgage Bonds"), being a supplement to the
Indenture, dated as of May 1, 1941 (the "Original First
Mortgage"), from the Company to the First Mortgage Trustee;

     (c)    the Bond Delivery Agreement, dated as of May 1,
1996, from the Company to the Bank mentioned above relating
to the First Mortgage Bonds; and

     (d)    the Custodian Agreement, dated as of May 1, 1996
(the "Custodian Agreement") from the Company to the Bank.


     The documents referred to above (other than the
Original First Mortgage) are herein collectively referred
to as the "Financing Documents."  The Original First
Mortgage, as amended and supplemented by all indentures
supplemental thereto including the First Mortgage
Supplement, is hereinafter referred to as the "First
Mortgage."

     In so acting we have reviewed all corporate
proceedings of the Company in connection with the
authorization, execution and delivery of the First Mortgage
and the Financing Documents and the authorization,
execution and issuance of the First Mortgage Bonds.  We
have also examined such other documents and satisfied
ourselves as to such other matters as we have deemed
necessary as a basis for the opinions set forth below.  We
have relied as to various questions of fact upon the
representations and warranties of the Company contained in
the Financing Documents, and in the certificates of public
officials and officers of the Company delivered thereunder
and have further relied upon certificates of the First
Mortgage Trustee as to the authentication of the First
Mortgage Bonds.  We do not serve as counsel to direct or
indirect subsidiaries or affiliates of the Company, and, as
to various questions relating to the activities of such
subsidiaries and affiliates, we have further relied upon
certificates of officers thereof and opinions of counsel
thereto.

     Based upon and subject to the foregoing, and subject
also to the qualifications hereinafter set forth, we are of
the opinion that:

     XXIV.          The Company (a) is duly organized, validly
existing and in good standing under the laws of the State
of Arizona, (b) has the corporate power and authority to
own and operate its property, to lease the property it
operates as lessee and to conduct the business in which it
is currently engaged, and (c) is duly qualified as a
foreign corporation and in good standing under the laws of
each jurisdiction where its ownership, lease or operation
of property or the conduct of its business requires such
qualification.

     XXV.      The Company has the corporate power and authority
to execute, deliver and perform the Financing Documents and
to incur indebtedness thereunder and to issue and deliver
the First Mortgage Bonds and has taken all necessary
corporate action to authorize the execution, delivery and
performance of the Financing Documents and to incur
indebtedness thereunder and issue and deliver the First
Mortgage Bonds.

     XXVI.          The First Mortgage and the Financing
Documents have been duly and validly executed and delivered
on behalf of the Company and constitute legal, valid and
binding obligations of the Company, enforceable against it
in accordance with their respective terms except that
certain of the remedial provisions of the First Mortgage
may be limited by the law of the state wherein the
mortgaged property is located and except as enforceability
may be limited by applicable bankruptcy, insolvency,
reorganization, moratoriums or other similar laws affecting
the enforcement of mortgagees' and other creditors' rights
generally and by general equitable principles (whether
enforcement is sought by proceedings in equity or at law)
and subject to any principles of public policy limiting the
right to enforce indemnification or contribution provisions
contained in the Financing Documents with respect to
liabilities under federal or state securities laws.

     XXVII.         The First Mortgage Bonds have been duly and
validly issued, executed and delivered by the Company and
authenticated by the First Mortgage Trustee and are legal,
valid and binding obligations of the Company enforceable in
accordance with their terms (subject to the exceptions
referred to in paragraph 3 above) and are entitled to the
security and benefits of the First Mortgage.

     XXVIII.        No consent or authorization of, filing with
or other act by or in respect of, the Securities and
Exchange Commission ("SEC"), the Federal Energy Regulatory
Commission ("FERC") or the Arizona Corporation Commission
("ACC") is required in connection with the incurrence of
indebtedness by the Company under the Reimbursement
Agreement or the issuance and delivery by the Company of
the First Mortgage Bonds or the mortgaging of the Company's
properties as security for the First Mortgage Bonds or the
execution, delivery or performance by the Company or the
enforceability against the Company of the First Mortgage,
the Financing Documents or the First Mortgage Bonds except
the Opinion and Order, dated April 24, 1996 of the ACC
relating thereto which has been obtained and is, to the
best of our knowledge, in full force and effect; provided,
however, that we express no opinion in this paragraph as to
compliance with the securities or "blue sky" laws of any
jurisdiction.


     XXIX.          The execution, delivery and performance by
the Company of the First Mortgage, and the Financing
Documents, the borrowings thereunder, the use of the
proceeds thereof and the issuance and delivery of the First
Mortgage Bonds will not violate any law administered by or
any rule or regulation of the SEC, the FERC or the ACC or
any material contractual obligation of the Company arising
out of, (1) the Master Restructuring Agreement, dated as of
June 30, 1992 (the "MRA"), among the Company, Escavada
Company, Gallo Wash Development Company, Valencia Energy
Company, the several banks parties thereto, and Barclays
Bank PLC, New York Branch, as Administrative Agent and
Collateral Agent, (2) the Company's Restated Articles of
Incorporation, (3) the First Mortgage or (4) any agreement
or other instrument, of which we have knowledge after due
inquiry (A) to which the Company is a party relating to
pollution control revenue bonds or industrial development
revenue bonds issued to finance projects of the Company,
(B) to which the Company is a party relating to the
Irvington Unit 4 Lease (as defined in the MRA), (C) to
which the Company is a party relating to the Valencia Lease
(as defined in the MRA), (D) to which the Company is a
party relating to the Springerville Common Lease (as
defined in the MRA) or (E) to which te Company is a party
relating to the Springerville Unit 1 Lease (as defined in
the MRA) and will not result in, or require, the creation
or imposition of any lien or other encumbrance on any of
its respective properties or revenues pursuant to any such
law, rule or regulation or any such material contractual
obligation other than as contemplated by the First Mortgage
and the Financing Documents.

     XXX.      No taxes (as distinguished from filing and
recordation fees) are payable to the State of New York or
any subdivision or agency thereof in connection with the
execution, delivery and filing or recordation of the First
Mortgage Supplement or any related filings or recordings,
or the execution, authentication, issuance or delivery of
the First Mortgage Bonds.

     XXXI.          (a)  The Company is not an "investment
Company," or a company "controlled" by an "investment
company," within the meaning of the Investment Company Act
of 1940, as amended.

          (b)  The Company and its subsidiaries are exempt
from all provisions of the Public Utility Holding Company
Act of 1935, as amended, except Section 9(a)(2) thereof.


     XXXII.         The obligations of the Company under the
Reimbursement Agreement are not subordinated to any other
indebtedness or obligations of the Company.

     XXXIII.        The provisions of Section 13.01 and
13.07(c)(ii) of the Indenture (as defined in the
Reimbursement Agreement), together with the Custodian
Agreement, are effective to create a valid and perfected
security interest in the Company's right, title and
interest in the Bonds (as defined in the Reimbursement
Agreement) from time to time pledged under the Custodian
Agreement and held by the Tender Agent (as defined in the
Indenture) in accordance with such provisions of the
Indenture.

     As members of the Bar of the State of New York, we do
not hold ourselves out as experts on the laws of other
jurisdictions except the laws of the United States, and, to
the extent that the opinions enumerated above are dependent
upon matters governed by the law of the State of Arizona or
the State of New Mexico, we have relied, with your consent,
upon the opinion of even date herewith rendered to you by
Dennis R. Nelson, Esq., Vice President and General Counsel
of the Company, and the opinions of even date herewith
rendered to you by Dickerman & Marvin, P.C. and Rodey,
Dickason, Sloan, Akin & Robb, P.A., counsel to the Company.

     Dennis R. Nelson, Esq., Dickerman & Marvin, P.C. and

Federal law covered hereby.  This letter is not being
