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,

     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

     succeeding Rate Period at a price payable in immediately

     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

     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

     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

     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;

     (iii)      all amounts required to be deposited into the

  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.

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.

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
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

  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;

  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

  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

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:

  pursuant to Section 8.01 hereof, such moneys to be applied
  only to the purchase of Bonds which are deemed to be paid

     (ii)  moneys furnished by the Company to the Tender Agent
  pursuant  to  Section 10.02 of the  Loan  Agreement  and

  under any Security Arrangement;

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

     (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.

required  to  be  tendered  pursuant  to  Section  2.02(h)
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

       accordance  with  the  directions  of  the  obligor
       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
agencies  is,  at  any  time while  the  contract  or  any
extension  of  the contact is in effect,  an  employee  or

respect to the subject matter of the contract.

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

Registered Owner of this Bond has the right to tender this
Bond  for  purchase  at the principal amount  hereof  plus

including  the payment of interest on such Bond after  the
tender date, other than the purchase price for such  Bond,

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

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

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
States  of America as, at the respective times of payment,

                    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
Control  Corporation has caused this Bond to  be  executed
with the manual or facsimile signature of its President or

     The Undersigned DTC Participant representing the beneficial
owner of the book-entry bonds described below (the "Tendered
Book-Entry Bonds") does hereby irrevocably tender the Tendered
Book-Entry Bonds to [      ] or its successor as Tender Agent
(the "Tender Agent", for purchase by the Tender Agent seven days
from the date of the Tender Agent's receipt, by telecopy or
otherwise, of this notice, or the next Business Day if such day
is not a Business Day* (the "Tender Date"); provided, however,
that if this notice is received by the Tender Agent by telecopy,
this notice shall be of no force or effect, and the Tendered
Book-Entry Bonds shall not be accepted or purchased by the Tender
Agent, unless the Tender Agent receives this notice in original
executed form by hand delivery prior to 2:00 p.m. New York time
on the Business Day next succeeding its receipt of such notice by
telecopy. The Purchase Price of Tendered Book-Entry Bonds shall
be the unpaid principal amount of the Tendered Book-Entry Bonds
plus accrued and unpaid interest, if any, thereon to, but not
including, the Tender Date, and without premium (the "Purchase
Price"). In the event that the Tender Date is also an interest

_________
*  "Business Day" shall have the meaning ascribed thereto by the
Indenture of Trust under which the    Bonds are issued.
    THE UNDERSIGNED ACKNOWLEDGES AND AGREES BY THE EXECUTION AND
DELIVERY OF THIS NOTICE (1) THAT THE TENDER OF THE TENDERED
BOOK-ENTRY BONDS IS IRREVOCABLE; (2) THAT THE UNDERSIGNED IS
CONTRACTUALLY BOUND TO TENDER SUCH TENDERED BOOK-ENTRY BONDS TO
THE TENDER AGENT ON THE TENDER DATE; AND (3) THAT IN THE EVENT OF
A FAILURE TO TENDER THE TENDERED BOOK-ENTRY BONDS TO THE TENDER
AGENT ON OR BEFORE 10:30 A.M. NEW YORK TIME ON THE TENDER DATE
THE UNDERSIGNED SHALL PAY TO THE TENDER AGENT AN AMOUNT (THE
"DEFAULT AMOUNT") EQUAL TO THE DIFFERENCE BETWEEN (A) THE COSTS
ARISING OUT OF THE FAILURE TO TENDER AND (B) THE PURCHASE PRICE,
AS DEFINED ABOVE, WHICH WOULD HAVE BEEN PAID TO THE UNDERSIGNED
UPON A TENDER. AS USED HEREIN THE "COSTS ARISING OUT OF THE
FAILURE TO TENDER" SHALL MEAN THE SUM OF (X) THE AMOUNT EXPENDED
BY THE TENDER AGENT, EITHER DIRECTLY OR THROUGH AN AGENT, IN
ACQUIRING BOOK-ENTRY BONDS IN SUBSTITUTION OF THE TENDERED

INCURRED IN CONNECTION WITH THE ACQUISITION OF SUCH SUBSTITUTE
BOOK-ENTRY BONDS.

DIRECTLY OR THROUGH AN AGENT, MAY ACQUIRE SUCH SUBSTITUTE BONDS
IN SUCH MANNER AND MARKET AS IT DEEMS COMMERCIALLY REASONABLE,

OF THE ANTICIPATED HARM CAUSED BY THE FAILURE TO TENDER AND THE
INCONVENIENCE OF OBTAINING ANY OTHER REMEDY.


    THE UNDERSIGNED HEREBY IRREVOCABLY APPOINTS THE TENDER AGENT
AS HIS DULY AUTHORIZED ATTORNEY AND DIRECTS THE TENDER AGENT TO
EFFECT THE TRANSFER OF THE TENDERED BOOK-ENTRY BONDS.
