$650,000                                                           June 29, 2001

         FOR VALUE RECEIVED,  FOCUS  Enhancements,  Inc, a Delaware  corporation
(the  "Company"),  with its  principal  office at 1370 Dell Ave.,  Campbell,  CA
95118, unconditionally promises to pay to the order of Carl Berg (the "Payee" or
the "Holder"),  or registered  assigns,  the principal amount of Six Hundred and
Fifty Thousand  Dollars  ($650,000) or such amount thereof as may be outstanding
(the  principal  balance as it may change from time to time being the "Principal
Amount") on January 3, 2003 (the  "Maturity  Date")  together  with  accrued and
unpaid interest  thereon,  in the manner set forth herein.  The Company may draw
down under this Note in one or more  drawdowns of not less than  $100,000 at any
time prior to January 3, 2003.  Each such  drawdown  shall be noted on Exhibit A
attached  to this  Note.  The  Company  further  agrees to pay  interest  on the
Principal  Amount at the rate per annum of "Prime"  rate of interest  plus 1% on
the outstanding  Principal Amount.  The Principal Amount is payable in such coin
or currency of the United  States of America as at the time of payment  shall be
legal  tender for the payment of public and  private  debts.  Interest  shall be
calculated  from and  including  from the date of this Note to but not including
the date such Principal  Amount has been repaid in full.  Interest shall be paid
quarterly  (based  upon a  calendar  quarter)  on the  twenty-fifth  day of each
quarter and shall be  calculated  on the basis of a 365-day or 366-day  year, as
the case may be,  for the  actual  number of days  elapsed.  The  Prime  rate of
interest rate shall be determined on the date of this Note and shall be adjusted
every July 1 and January 1 of each year (the "Interest Rate Determination Date")
based on the Prime rate published in Western  Edition of The Wall Street Journal
on the last business day immediately  preceding the Interest Rate  Determination
Date.

         Each payment by the Company pursuant to this Note shall be made without
set-off or counterclaim and in immediately available funds.

         The Company (i) waives  presentment,  demand,  protest or notice of any
kind  (other  than  notice of  default)  in  connection  with this Note and (ii)
agrees, in the event of an Event of Default,  to pay to the holder of this Note,
on demand, all reasonable costs and expenses  (including legal fees) incurred in
connection with the enforcement and collection of this Note.

     1. Security Agreement. This Note is entitled to the benefit of that certain
Security  Agreement,  dated as of October 26, 2000 between Payee and the Company
(as amended from time to time hereafter, the "Security Agreement"),  pursuant to
which Payee is granted a first priority  security interest in the Collateral (as
such term is defined in the Security  Agreement).  This Note shall be subject to
the terms and conditions set forth in such Security Agreement.

     2. Conversion into Preferred Stock.

         A. The Note can be converted  upon the mutual  agreement of the Company
and the Holder. Furthermore, the Holder, upon written notice to the Company, can
elect to accept payment of interest on the Note in the form of Common Stock. The
value of such Common Stock issued in lieu of interest payments shall be based on
the  average of the  closing  bid and ask price of the Common  Stock on the last
trading day immediately preceding the date interest is payable.

         B. Conversion  Price.  The per share price of the Preferred Stock shall
be 1,000  multiplied by 125% of the trailing 30-day average closing price of the
Company's  common stock  ending June 28, 2001  ("Moving  Average").  In no event
shall the Moving Average be less than $1.07.

         C.  Terms.  Such  Preferred  Stock  shall be  subject  to the terms and
conditions  of the  Certificate  of  Designation,  substantially  in the form as
previously  approved by the Board in  connection  with its approval of Amendment
No. 1 to Secured  Promissory  Note dated April 24, 2001 issued by the Company to
Carl Berg  ("April  Amended  Note"),  subject to any  adjustments  necessary  to
reflect the terms of this Note.

         D. Issue  Taxes.  The  Company  shall pay any and all stamp,  issue and
other  taxes that may be payable in respect of the  issuance  or delivery of the
Preferred Stock.

         E. Reservation of Stock Issuable Upon Conversion.  The Company shall at
all times reserve and keep available out of its  authorized but unissued  shares
of Common Stock, solely for the purpose of effecting the conversion of this Note
as  described  in this Section 2, such number of its shares of Common Stock from
time to time issuable upon the conversion  hereof. If at any time such number of
authorized but unissued shares of Common Stock shall not be sufficient to effect
the conversion of the Preferred  Stock, the Company will take all such corporate
action as may be  necessary to increase its  authorized  but unissued  shares of
Common Stock,  to such number of shares as shall be sufficient for such purpose,
including,  without limitation,  obtaining the requisite stockholder approval of
any necessary amendment to the Company's certificate of incorporation.

         F. Registration Rights. The underlying Common Stock shall be subject to
an Investor Rights' Agreement  substantially in the form as previously  approved
by the Board in connection with its approval of the April Amended Note,  subject
to any adjustments necessary to reflect the terms of this Note.

         AND IT IS HEREBY FURTHER CONFIRMED by the Company that all the terms,
conditions, provisos, covenants and provisions contained in the Mortgage shall
affect and apply to the property in the Mortgage described and conveyed, and to
the estates, rights, obligations and duties of the Company and the Trustee and
the beneficiaries of the trust with respect to said property, and to the Trustee
and its successors in the trust, in the same manner and with the same effect as
if the said property had been owned by the Company at the time of the execution
of the Original Mortgage, and had been specifically and at length described in
and conveyed to said Trustee by the Original Mortgage as a part of the property
therein stated to be conveyed.

         The Company further covenants and agrees to and with the Trustee and
its successor or successors in such trust under the Mortgage, as follows:

                         TWENTY-SEVENTH SERIES OF BONDS

         (I) There shall be a series of bonds designated "First Mortgage Bonds,
7.75% Series due 2007" (herein sometimes referred to as the "bonds of the
Twenty-seventh Series" or the "Bonds"), and the form thereof, which has been
established by Resolution of the Board of Directors of the Company, is set forth
on Exhibit C hereto. The bonds of the Twenty-seventh Series shall be issued as
fully registered bonds in denominations of One Thousand Dollars and, at the
option of the Company, any amount in excess thereof (the exercise of such option
to be evidenced by the execution and delivery thereof) and shall be dated as in
Section 10 of the Mortgage provided.

         (II) The Bonds of the Twenty-seventh Series shall mature, shall bear
interest and shall be payable as set forth below:

the principal of bonds of the Twenty-seventh Series shall (unless theretofor
paid) be payable on the Stated Maturity Date (as hereinafter defined);

the Bonds of the Twenty-seventh Series shall bear interest at the rate of seven
and seventy-five one-hundredths per centum (7.75%) per annum; interest on such
bonds shall accrue from and including the date of the initial authentication and
delivery thereof, except as otherwise provided in the form of bond attached
hereto as Exhibit C; interest on such bonds shall be payable on each Interest
Payment Date and at Maturity (as each of such terms is hereafter defined); and
interest on such bonds during any period for which payment is made shall be
computed on the basis of a 360-day year consisting of twelve 30-days months;

the principal of and premium, if any, and interest on each bond of the
Twenty-seventh Series payable at Maturity shall be payable upon presentation
thereof at the office or agency of the Company in the Borough of Manhattan, The
City of New York, in such coin or currency as at the time of payment is legal
tender for public and private debts. The interest on each bond of the
Twenty-seventh Series (other than interest payable at Maturity) shall be payable
by check, in similar coin or currency, mailed to the registered owner thereof as
of the close of business on the Record Date next preceding each Interest Payment
Date; provided, however, that if such registered owner shall be a securities
depositary, such payment may be made by such other

                                       6
<PAGE>

means in lieu of check as shall be agreed upon by the Company, the Trustee and
such registered owner.

         (III) The bonds of the Twenty-seventh Series shall not be subject to
redemption prior to the Stated Maturity Date.

         (IV) (a) At the option of the registered owner, any bonds of the
Twenty-seventh Series, upon surrender thereof for cancellation at the office or
agency of the Company in the Borough of Manhattan, The City of New York, shall
be exchangeable for a like aggregate principal amount of bonds of the same
series of other authorized denominations.

         The bonds of the Twenty-seventh Series shall be transferable, upon the
surrender thereof for cancellation, together with a written instrument of
transfer in form approved by the registrar duly executed by the registered owner
or by his duly authorized attorney, at the office or agency of the Company in
the Borough of Manhattan, The City of New York.

         Notwithstanding the foregoing, if any bond to be transferred in whole
or in part is a Restricted Definitive Bond, or is a Regulation S Definitive Bond
and the transfer is to occur during the Restricted Period, then such transfer
may be effect only if the Trustee and the Company shall have received from the
transferor (1) a Restricted Securities Certificate, satisfactory to the Company
and duly executed by the registered holder or his attorney duly authorized in
writing, in which case the transferee shall take delivery in the form of a
Restricted Bond or (2) a Regulation S Certificate, satisfactory to the Company
and duly executed by the registered holder or his attorney duly authorized in
writing, in which case the transferee shall take delivery in the form of a
Regulation S Bond.

         Terms used in this Article which have not been heretofore defined or
are not defined in this Article are defined in Article III.

         Upon any exchange or transfer of bonds of the Twenty-seventh Series,
the Company may make a charge therefor sufficient to reimburse it for any tax or
taxes or other governmental charge, as provided in Section 12 of the Mortgage,
but the Company hereby waives any right to make a charge in addition thereto or
any exchange or transfer of bonds of the Twenty-seventh Series; provided,
however, that the Company shall not be required to make any transfer or exchange
of any bonds of the Twenty-seventh Series for a period of 10 days next preceding
any selection of such bonds for redemption, nor shall it be required to make
transfers or exchange of any bonds of the Twenty-seventh Series which shall have
been selected for redemption in whole or in part or as to which the Company
shall have received a notice for the redemption thereof in whole or in part at
the option of the registered owner.

         (b) The bonds of the Twenty-seventh Series are initially to be issued
in global form, registered in the name of Cede & Co., as nominee for The
Depository Trust Company (the "Depositary"), as provided in Article III hereof.
Notwithstanding the provisions of subdivision (a) above, such bonds shall not be
transferable, nor shall any purported transfer be registered, except as follows:

               (i) such bonds may be transferred in whole, and appropriate
          registration of transfer effected, to the Depositary, or by the
          Depositary to another nominee thereof, or by any nominee of the

                                       7
<PAGE>

          Depositary to any other nominee thereof, or by the Depositary or any
          nominee thereof to any successor securities depositary or any nominee
          thereof;

               (ii) such bonds may be transferred in whole, and appropriate
          registration of transfer effected, to the beneficial holders thereof,
          and thereafter shall be transferable subject to subsection (c) below,
          if:

                    (A) The Depositary, or any successor securities depositary,
               shall have notified the Company and the Trustee that (I) it is
               unwilling or unable to continue to act as securities depositary
               with respect to such bonds or (II) it is no longer a clearing
               agency registered under the Securities Exchange Act of 1934, as
               amended, and, in either case, the Trustee shall not have been
               notified by the Company within one hundred twenty (120) days of
               the identity of a successor securities depositary with respect to
               such bonds; or

                    (B) the Company shall have delivered to the Trustee a
               written order to the effect that such bonds shall be so
               transferable on and after a date specified therein.

               The bonds of the Twenty-seventh Series, when in global form,
shall bear a legend as to such global form and the foregoing restrictions on
transfer substantially as set forth below:

                This global bond is held by Cede & Co., as nominee for The
                Depository Trust Company (the "Depositary") for the benefit of
                the beneficial owners hereof. This bond may not be
                transferred, nor may any purported transfer be registered,
                except that (i) this bond may be transferred in whole, and
                appropriate registration of transfer effected, if such
                transfer is by Cede & Co., as nominee for the Depositary, 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 bonds depositary or any nominee thereof; and
                (ii) this bond may be transferred, and appropriate
                registration of transfer effected, to the beneficial holders
                hereof, and thereafter shall be transferable without
                restrictions (except as provided in the preceding paragraph)
                if: (A) the Depositary, or any successor securities
                depositary, shall have notified the Company and the Trustee
                that (I) it is unwilling or unable to continue to act as
                securities depositary with respect to the bonds or (II) it is
                no longer a clearing agency registered under the Securities
                Exchange Act of 1934, as amended, and, in either case, the
                Trustee shall not have been notified by the Company within one
                hundred twenty (120) days of the identity of a successor
                securities depositary with respect to the bonds; or (B) the
                Company shall have delivered to the Trustee a written order to
                the effect that the bonds shall be so transferable on and
                after a date specified therein.

                Any certificated Bond issued in exchange for an interest in a
Global Bond will bear the legend restricting transfers that is borne by such
Global Bond.

         (c)    Unless and until the Company shall have delivered to the Trustee
a written order to the contrary in accordance with this Twenty-ninth
Supplemental Indenture, each global bond of the Twenty-seventh Series shall bear
a legend to the effect of clause (b) above, and each bond of such series shall
bear a further legend as follows:

                (i)   in the case of a bond offered and sold in reliance on
         Rule 144A,

                and may not be offered, sold, pledged or otherwise transferred
                except (1) to a person whom the seller reasonably believes is

                144A under Securities Act purchasing for its own account or

                by Rule 144 thereunder (if available), in each case, in
                accordance with all applicable securities laws of the states
                of the Untied States."

                (ii) in the case of a bond offered and sold in reliance on

                and may not be offered, sold or delivered in the United States
                or to, or for the account or benefit of, any U.S. person,
                unless the bonds are registered under the Securities Act or an
                exemption from the registration requirements of the Securities
                Act is available."

                (V) For all purposes of this Twenty-ninth Supplemental

delivery by the Trustee of the bonds of the Twenty-seventh Series, the Company

and Pledged Property in the face amount of $150,000,000. The Trustee shall hold

beneficial interest in the 144A Global Bond wishes at any time to transfer such
interest to a Person who wishes to acquire the same in the form of a beneficial
interest in the Regulation S Global Bond, such transfer may be effected only in
accordance with the provisions of this subsection (a) and subject to the
Applicable Procedures. Upon receipt by the Custodian and the Company of (i) an
order given by the Depositary or its authorized representative directing that a
beneficial interest in such 144A Global Bond in a specified principal amount be
debited from a specified Agent Member's account and that a beneficial interest
in the corresponding Regulation S Global Bond in an equal principal amount be
credited to another specified Agent Member's account and (ii) a Regulation S
Certificate (in the form of Exhibit D hereto), satisfactory to the Company and
duly executed by the owner of such beneficial interest in the 144A Global Bond
or his attorney duly authorized in writing, then the Custodian shall reduce the
principal amount of such 144A Global Bond and increase the principal amount of
the corresponding Regulation S Global Bond by such specified principal amount.

         (b)    Regulation S Global Bond to 144A Global Bond. If the owner of a
beneficial interest in the Regulation S Global Bond wishes at any time to
transfer such interest to a Person who wishes to acquire the same in the form of
a beneficial interest in the corresponding 144A Global Bond, such transfer may
be effected only in accordance with this subsection (b) and subject to the
Applicable Procedures. Upon receipt by the Custodian and the Company of (i) an
order given by the Depositary or its authorized representative directing that a
beneficial interest in such Regulation S Global Bond in a specified principal
amount be debited from a specified Agent Member's account and that a beneficial
interest in the corresponding 144A Global Bond in an equal principal amount be
credited to another specified Agent Member's account and (ii) if such transfer
is to occur during the Restricted Period, a Restricted Securities Certificate
(in the form of Exhibit E hereto), satisfactory to the Company and duly executed
by the owner of such beneficial interest in such Regulation S Global Bond or his
attorney duly authorized in writing, then the Custodian shall reduce the
principal amount of such Regulation S Global Bond and

                                       13
<PAGE>

increase the principal amount of the corresponding 144A Global Bond by such
specified principal amount.

         (c)    Exchange Offer. Upon the consummation of the Exchange Offer, the
Company shall execute and deliver, and the Trustee shall authenticate (i) one or
more Global Bonds which bear neither the Private Placement Legend nor the
Regulation S Legend in an aggregate principal amount equal to the principal
amount of the beneficial interests in the 144A Global Bonds and the Regulation S
Global Bonds validly tendered and accepted for exchange in accordance with the
terms of the Exchange Offer or (ii) Definitive Bonds which bear neither the
Private Placement Legend nor the Regulation S Legend in an aggregate principal
amount equal to the principal amount of the Restricted Definitive Bonds and the
Regulation S Definitive Bonds validly tendered and accepted for exchange in

         AVISTA CORPORATION, a corporation of the State of Washington

                                                                         DOLLARS

or such other principal amount as is set forth in the Schedule of Exchanges of
Interests in the Global Bond attached hereto, and to pay the registered owner
hereof interest thereon from December 19, 2001 semi-annually in arrears on
January 1 and July 1 in each year (each such date being hereinafter called an
"Interest Payment Date"), commencing July 1, 2002, and at Maturity (as
hereinafter defined), at the rate of seven and seventy-five one-hundredths per
centum (7.75%) per annum, computed on the basis of a 360-day year consisting of

of such principal shall have been discharged. The principal of and premium, if
any, and interest on this bond payable at Maturity shall be paid upon

debts. The interest on this bond (other than interest payable at Maturity) shall
be paid by check, in the similar coin or currency, mailed to the registered
owner hereof as of the close of business on the December 15 or June 15, as the
case may be, next preceding each Interest Payment Date (each such date being
herein called a "Record Date"); provided, however, that if such registered owner
shall be a securities depositary, such payment shall be made by such other means
in lieu of check as shall be agreed upon by the Company, the Trustee and such
registered owner. Interest payable at Maturity shall be paid to the person to
whom principal shall be paid. As used herein, the term "Maturity" shall mean the
date on which the principal of this bond becomes due and payable, whether at
stated maturity, upon redemption or acceleration, or otherwise.

         This bond is one of an issue of bonds of the Company issuable in series
and is one of a series known as its First Mortgage Bonds, 7.75% Series due 2007,
all bonds of all such issue of series being issued and issuable under and
equally secured (except insofar as any sinking or other fund, established in
accordance with the provisions of the Mortgage hereinafter mentioned, may afford
additional security for the bonds of any particular series) by a Mortgage and
Deed of Trust, dated as of June 1, 1939, executed by the Company (formerly known
as The Washington Water Power Company) to City Bank Farmers Trust Company and
Ralph E. Morton, as Trustees (Citibank, N.A., successor Trustee to both said
Trustees). Such mortgage and deed of trust has been amended and supplemented by
various supplemental indentures, including the Twenty-ninth Supplemental
Indenture, dated as of December 1, 2001 (the "Twenty-ninth Supplemental
Indenture") and, as so amended and supplemented, is herein called the
"Mortgage". Reference is made to the Mortgage for a description of the property
mortgaged and pledged, the nature and extent of the security, the rights of the
holders of the bonds and of the Trustee in respect thereof, the duties and
immunities of the Trustee and the terms and conditions upon which the bonds are
and are to be secured and the circumstances under which additional bonds may be
issued. If there shall be a conflict between the terms of this bond and the
provisions of the Mortgage, the provisions of the Mortgage shall control to the
extent permitted by law. The holder of this bond, by its acceptance hereof,
shall be deemed to have consented and agreed to all terms and provisions of the
Mortgage and, further, in the event that such holder shall not be the sole
beneficial owner of this bond, shall be deemed to have agreed to use all
commercially reasonable efforts to cause all direct and indirect beneficial
owners of this bond to have knowledge of the terms and provisions of the
Mortgage and of this bond and to comply therewith, including particularly, but
without limitation, any provisions or restrictions in the Mortgage regarding the
transfer or exchange of such beneficial interests and any legend set forth on
this bond.

         With the consent of the Company and to the extent permitted by and as
provided in the Mortgage, the rights and obligations of the Company and/or the
rights of the holders of the bonds and/or coupons and/or the terms and
provisions of the Mortgage may be modified or altered by affirmative vote of the
holders of at least 75% in principal amount of the bonds then outstanding under
the Mortgage and, if the rights of one or more, but less than all, series of
bonds then outstanding are to be affected, then also by affirmative vote of the
holders of at least 75% in principal amount of the series of bonds so to be
affected (excluding in any case bonds challenged and disqualified from voting by
reason of the Company's interest therein as provided in the Mortgage). The
Company has amended the Mortgage, effective as of the Modification Effective
Date (as defined in the Twenty-ninth Supplemental Indenture), to provide that
the Mortgage may be modified or altered by affirmative vote of the holders of at
least 60% in principal amount of the bonds outstanding under the Mortgage,
considered as one class, or, if the rights of one or more, but less than all,
series of bonds then outstanding are to be affected, then such modification or
alteration may be effected with the affirmative vote only of 60% in principal
amount of the bonds outstanding of the series so to be affected, considered as
one class, and, furthermore, to provide that, for limited purposes, the Mortgage
may be modified or altered without any consent or other action of holders of any
series of bonds. No modification or alteration shall, however, permit an
extension of the Maturity of the principal of, or interest on, this bond or a
reduction in such principal or the rate of interest hereon or any other
modification in the terms of payment of such principal or interest or the
creation of any lien equal or prior to the lien of the Mortgage or deprive the
holder of a lien on the mortgaged and pledged property without the consent of
the holder hereof.

         The principal hereof may be declared or may become due prior to the
stated maturity date on the conditions, in the manner and at the time set forth
in the Mortgage, upon the occurrence of a completed default as in the Mortgage
provided.

         In the manner prescribed in the Mortgage, this bond is transferable by
the registered owner hereof in person, or by his duly authorized attorney, at
the office or agency of the Company in the Borough of Manhattan, The City of New
York, upon surrender and cancellation of this bond, together with a written
instrument of transfer whenever required by the Company duly executed by the
registered owner or by its duly authorized attorney, and, thereupon, a new fully
registered bond of the same series for a like principal amount will be issued to
the transferee in exchange herefor as provided in the Mortgage. The Company and
the Trustee may deem and treat the person in whose name this bond is registered
as the absolute owner hereof for the purpose of receiving payment and for all
other purposes.

         In the manner prescribed in the Mortgage, any bonds of this series,
upon surrender thereof for cancellation at the office or agency of the Company
in the Borough of Manhattan, The City of New York, are exchangeable for a like
aggregate principal amount of bonds of the same series of other authorized
denominations.

         The bonds of this series are not subject to redemption prior to the
stated maturity date thereof.

         No recourse shall be had for the payment of the principal of or
interest on this bond against any incorporator or any past, present or future
subscriber to the capital stock, stockholder, officer or director of the Company
or of any predecessor or successor corporation, as such, either directly or
through the Company or any predecessor or successor corporation, under any rule
of law, statute or constitution or by the enforcement of any assessment or
otherwise, all such liability of incorporators, subscribers, stockholders,
officers and directors being released by the holder or owner hereof by the
acceptance of this bond and being likewise waived and released by the terms of
the Mortgage.

         This bond shall not become obligatory until Citibank, N.A., the Trustee
under the Mortgage, or its successor thereunder, shall have signed the form of
certificate endorsed hereon.

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

Reference is made to the Mortgage and Deed of Trust, dated as of June 1, 1939,
between Avista Corporation (the "Company") and Citibank, N.A., successor
Trustee, as amended and supplemented (the "Mortgage"). Terms used herein and
defined in the Mortgage or in Regulation S or Rule 144 under the U.S. Securities
Act of 1933, as amended (the "Securities Act") are used herein as so defined.

This certificate relates to U.S. $_____________ principal amount of Bonds, which
are evidenced by the following certificate(s) (the "Specified Bonds"):

CUSIP No(s). ___________________________

CERTIFICATE No(s). _____________________

         The person in whose name this certificate is executed below (the
"Undersigned") hereby certifies that either (i) it is the sole beneficial owner
of the Specified Bonds or (ii) it is acting on behalf of all the beneficial
owners of the Specified Bonds and is duly authorized by them to do so. Such
beneficial owner or owners are referred to herein collectively as the "Owner."
If the Specified Bonds are represented by a Global Bond, they are held through
the Depositary or an Agent Member in the name of the Undersigned, as or on
behalf of the Owner. If the Specified Bonds are not represented by a Global
Bond, they are registered in the name of the Undersigned, as or on behalf of the
Owner.

The Owner has requested that the Specified Bonds be transferred to a person (the
"Transferee") who will take delivery in the form of a Regulation S Bond. In
connection with such transfer, the Owner hereby certifies that, unless such
transfer is being effected pursuant to an effective registration statement under
the Securities Act, it is being effected in accordance with Rule 904 or Rule 144
under the Securities Act and with all applicable securities laws of the states
of the United States and other jurisdictions. Accordingly, the Owner hereby
further certifies as follows:

         (1)  Rule 904 Transfers.  If the transfer is being effected in
accordance with Rule 904:

                                      D-1
<PAGE>

                (A) the Owner is not a distributor of the Bonds, an affiliate of
          the Company or any such distributor or a person acting on behalf of
          any of the foregoing;

               (B) the offer of the Specified Bonds was not made to a person in
          the United States;

               (C) either: (i) at the time the buy order was originated, the
          Transferee was outside the United States or the Owner and any person
          acting on its behalf reasonably believed that the Transferee was
          outside the United States, or (ii)the transaction is being executed
          in, on or through the facilities of the Eurobond market, as regulated
          by the Association of International Bond Dealers, or another
          designated offshore securities market and neither the Owner nor any
          person acting on its behalf knows that the transaction has been
          prearranged with a buyer in the United States;

               (D) no directed selling efforts have been made in the United
          States by or on behalf of the Owner or any affiliate thereof;

               (E) if the Owner is a dealer in securities or has received a
          selling concession, fee or other remuneration in respect of the
          Specified Bonds, and the transfer is to occur during the Restricted
          Period, then the requirements of Rule 904(c)(1) have been satisfied;
          and

               (F) the transaction is not part of a plan or scheme to evade the
          registration requirements of the Securities Act.

         (2)   Rule 144 Transfers. If the transfer is being effected pursuant to

                (A) the Specified Bonds are being transferred to a person that
          the Owner and any person acting on its behalf reasonably believe is a
          "qualified institutional buyer" within the meaning of Rule 144A,
          acquiring for its own account or for the account of a qualified
          institutional buyer; and

                (B) the Owner and any person acting on its behalf have taken
          reasonable steps to ensure that the Transferee is aware that the Owner
          may be relying on Rule 144A in connection with the transfer.

         (2) Rule 144 Transfers. If the transfer is being effected pursuant to
Rule 144:

          or from an affiliate of the Company, whichever is later, and is being
          effected in accordance with the applicable amount, manner of sale and
          notice requirements of Rule 144; or

          not been, an affiliate of the Company.

                                    AMENDMENTS TO MORTGAGE

         (1) The amendment of Article XVIII of the Original Mortgage to read as
follows:

                                 ARTICLE XVIII.

                      MEETINGS AND CONSENTS OF BONDHOLDERS.

         SECTION 107. Modifications and alterations of this Indenture and/or of
any indenture supplemental hereto and/or of the rights and obligations of the
Company and/or of the rights of the holders of bonds and coupons issued
hereunder may be made as provided in this Article XVIII.

         SECTION 108. The Corporate Trustee may at any time call a meeting of
the holders of bonds of one or more, or all, series and it shall call such a
meeting on written request of the Company, given pursuant to a Resolution of its
Board of Directors, or a resolution of the holders of a majority or more in
principal amount of the bonds of such series Outstanding hereunder, considered
as one class, at the time of such request. In the event of the Corporate
Trustee's failing for ten (10) days to call a meeting after being thereunto
requested by the Company or bondholders as above set forth, holders of
Outstanding bonds in the amount above specified in this Section or the Company,
pursuant to Resolution of its Board of Directors, may call such meeting. Every
such meeting called by and at the instance of the Corporate Trustee shall be
held in the Borough of Manhattan, The City of New York, or with the written
approval of the Company, at any other place in the United States of America, and
written notice thereof, stating the place and time thereof and in general terms
the business to be submitted, shall be mailed by the Corporate Trustee not less
than thirty (30) days before such meeting (a) to each registered holder of bonds
of the series in respect of which such meeting is being called, then Outstanding
hereunder addressed to him at his address appearing on the registry books, (b)
to all other holders of bonds of such series then Outstanding hereunder the
names and addresses of whom are preserved by the Corporate Trustee as required
by the provisions of Section 132 hereof and (c) to the Company addressed to it
at Spokane, Washington (or at such other address as may be designated by the
Company from time to time), and, if any bonds of such series shall not be in
fully registered form, shall be published by the Corporate Trustee at least once
a week for four (4) successive calendar weeks immediately preceding the meeting,
upon any secular day of each such calendar week, which need not be the same day
of each week, in a Daily Newspaper, printed in the English language, and
published and of general circulation in The City of New York; provided, however,
that, if such notice by publication shall have been given, the mailing of such
notice to any bondholders shall in no case be a condition precedent to the
validity of any action taken at such meeting. Any meeting of holders of the
bonds of one or more, or all, series shall be valid without notice if the
holders of all bonds of such series then Outstanding hereunder are present in
person or by proxy and if the Company and the Corporate Trustee are present by
duly authorized representatives, or if notice is waived in writing before or

<PAGE>

after the meeting by the Company, the holders of all bonds of such series
Outstanding hereunder and by the Corporate Trustee, or by such of them as are
not present in person or by proxy.

         SECTION 109. Officers and nominees of the Corporate Trustee and of the
Company may attend such meeting, but shall not as such be entitled to vote
thereat. Attendance by bondholders may be in person or by proxy. In order that
the holder of any bond payable to bearer and his proxy may attend and vote
without producing his bond, the Corporate Trustee, with respect to any such
meeting, may make and from time to time vary such regulations as it shall think
fit for deposit of bonds with, (i) any bank or trust or insurance company, or
(ii) any trustee, secretary, administrator or other proper officer of any
pension, welfare, hospitalization, or similar fund or funds, or (iii) the United
States of America, any Territory thereof, the District of Columbia, any State of
the United States, any municipality in any State of the United States or any
public instrumentality of the United States, or of any State or of any
Territory, or (iv) any other person or corporation satisfactory to the Corporate
Trustee, and for the issue to the persons depositing the same of certificates by
such depositaries entitling the holders thereof to be present and vote at any
such meeting and to appoint proxies to represent them and vote for them at any
such meeting in the same way as if the persons so present and voting, either
personally or by proxy, were the actual bearers of the bonds in respect of which
such certificate shall have been issued and any regulations so made shall be
binding and effective. A bondholder in any of the foregoing categories may sign
such a certificate in his own behalf. In lieu of or in addition to providing for
such deposit, the Corporate Trustee may, in its discretion, permit such
institutions to issue certificates which shall entitle the holders thereof to
vote at any meeting only if the bonds with respect to which they are issued are
not produced at the meeting by any other person and are not at the time of the
meeting registered in the name of any other person. Each such certificate shall
state the date on which the bond or bonds in respect of which such certificate
shall have been issued were deposited with or exhibited to such institution and
the series, maturities and serial numbers of such bonds. A bondholder in any of
the foregoing categories may sign such a certificate in his own behalf. In the
event that two or more such certificates shall be issued with respect to any
bond or bonds, the certificate bearing the latest date shall be recognized and
be deemed to supersede any certificate or certificates previously issued with
respect to such bond or bonds. If any such meeting shall have been called by
bondholders or by the Company as aforesaid upon failure of the Corporate Trustee
to call the same after having been so requested under the provisions of Section
108 hereof, regulations to like effect for such deposit of bonds and the issue
of certificates by (i) any bank or trust or insurance company organized under
the laws of the United States of America or of any state thereof, or (ii) any
trustee, secretary, administrator or other proper officer of any pension,
welfare, hospitalization, or similar fund or funds, or (iii) the United States
of America, any Territory thereof, the District of Columbia, any State of the
United States, any municipality in any State of the United States or any public
instrumentality of the United States, or of any State or of any Territory, shall
be similarly binding and effective for all purposes hereof if adopted or
approved by the bondholders calling such meeting or by the Board of Directors of
the Company, if such meeting shall have been called by the Company, provided
that in either such case copies of such regulations shall be filed with the

                                      F-2
<PAGE>

Corporate Trustee. A bondholder in any of the foregoing categories may sign such
a certificate in his own behalf.

         SECTION 110. Subject to the restrictions specified in Sections 109 and
113 hereof, any registered holder of bonds Outstanding hereunder and any holder
of a certificate provided for in Section 109 hereof relating to bonds
Outstanding hereunder, in either case of the series in respect of which a
meeting shall have been called, shall be entitled in person or by proxy to
attend and vote at such meeting as a holder of the bonds registered or certified
in the name of such holder without producing such bonds. All others seeking to
attend or vote at such meeting in person or by proxy must, if required by any
authorized representative of the Corporate Trustee or the Company or by any
other bondholder, produce the bonds claimed to be owned or represented at such
meeting and every one seeking to attend or vote shall, if required as aforesaid,
produce such further proof of bond ownership or personal identity as shall be
satisfactory to the authorized representative of the Corporate Trustee, or if
none be present then to the Inspectors of Votes hereinafter provided for.
Proxies shall be witnessed or in the alternative may (a) have the signature
guaranteed by a bank or trust company or a registered dealer in securities, (b)
be acknowledged before a Notary Public or other officer authorized to take
acknowledgements, or (c) have their genuineness otherwise established to the
satisfaction of the Inspector of Votes. All proxies and certificates presented
at any meeting shall be delivered to said Inspectors of Votes and filed with the
Corporate Trustee.

         SECTION 111. Persons nominated by the Corporate Trustee if it is
represented at the meeting shall act as temporary Chairman and Secretary,
respectively, of the meeting, but if the Corporate Trustee shall not be
represented or shall fail to nominate such persons or if any person so nominated
shall not be present, the bondholders and proxies present shall by a majority
vote, irrespective of the amount of their holdings, elect another person or
other persons from those present to act as temporary Chairman and/or Secretary.
A permanent Chairman and a permanent Secretary of such meeting shall be elected
from those present by the bondholders and proxies present by a majority vote
irrespective of the amount of their holdings. The Corporate Trustee, if
represented at the meeting, shall appoint two Inspectors of Votes who shall
decide as to the right of anyone to vote and shall count all votes cast at such
meeting, except votes on the election of a Chairman and Secretary, both
temporary and permanent, as aforesaid, and who shall make and file with the
permanent Secretary of the meeting their verified written report in duplicate of
all such votes so cast at said meeting. If the Corporate Trustee shall not be
represented at the meeting or shall fail to nominate such Inspectors of Votes or
if either Inspector of Votes fails to attend the meeting, the vacancy shall be
filled by appointment by the permanent Chairman of the meeting.

         SECTION 112. The holders of a majority in aggregate principal amount of
the bonds Outstanding hereunder of the series with respect to which a meeting
shall have been called as hereinbefore provided, considered as one class, shall
constitute a quorum for a meeting of holders of bonds of such series; provided,
however, that if any action is to be taken at such meeting which this Indenture
expressly provides may be taken by the holders of not less than sixty per centum
(60%) in principal amount of the bonds of such series Outstanding hereunder,
considered as one class, the holders of such percentage in principal amount of

                                      F-3
<PAGE>

the bonds of such series Outstanding hereunder, considered as one class, shall
constitute a quorum; and provided, further, that if any action is to be taken at
such meeting which this Indenture expressly provides may be taken by the holders
of a specified percentage which is less than a majority in principal amount of
the bonds of such series Outstanding hereunder, considered as one class, the
holders of such specified percentage in principal amount of the bonds of such
series Outstanding hereunder, considered as one class, shall constitute a
quorum. In the absence of a quorum within one hour of the time appointed for any
such meeting, the meeting shall, if convened at the request of holders of bonds
of such series, be dissolved. In any other case the meeting may be adjourned for
such period or periods as may be determined by the chairman of the meeting prior
to the adjournment thereof.

         SECTION 113. Any modification or alteration of this Indenture and/or of
any indenture supplemental hereto and/or of the rights and obligations of the
Company and/or the rights of the holders of bonds and/or coupons issued
hereunder in any particular may be made at a meeting of bondholders duly
convened and held in accordance with the provisions of this Article, but only by
resolution duly adopted by the affirmative vote of the holders of sixty per
centum (60%) or more in principal amount of the bonds Outstanding hereunder,
considered as one class (or, if such modification or alteration shall directly
affect the holders of bonds of one or more, but less than all, series then
Outstanding hereunder, then the affirmative vote only of the holders of sixty
per centum (60%) or more in aggregate principal amount of the bonds of the
series so directly affected then Outstanding hereunder, considered as one
class), when such meeting is held, and in every case approved by Resolution of
the Board of Directors of the Company as hereinafter specified; provided,
however, that no such modification or alteration shall, without the consent of
the holder of any bond issued hereunder affected thereby, permit (1) the
extension of the maturity of the principal of, or interest on, such bonds, or
(2) the reduction in such principal or the rate of interest thereon or any other
modification in the terms of payment of such principal or interest, or (3) the
creation of any lien ranking prior to, or on a parity with, the Lien of this
Indenture with respect to any of the Mortgaged and Pledged Property, or (4) the
deprivation of any non-assenting bondholder of a lien upon the Mortgaged and
Pledged Property for the security of his bonds (subject only to Excepted
Encumbrances) or (5) the reduction of the percentage required by the provisions
of this Section for the taking of any action under this Section with respect to
any bond Outstanding hereunder. For all purposes of this Article, the Trustees
shall be entitled to rely upon an Opinion of Counsel with respect to the extent,
if any, as to which any action taken at such meeting affects the rights under
this Indenture or under any indenture supplemental hereto of any holders of
bonds then Outstanding hereunder.

         Bonds owned and/or held by and/or for account of and/or for the benefit
or interest of the Company, or any corporation of which the Company shall own
twenty-five per centum (25 %) or more of the outstanding voting stock, shall not
be deemed Outstanding for the purpose of any vote or of any calculation of bonds
Outstanding in Article XVI hereof or in this Article XVIII or for the purpose of
the quorum provided for in Section 112 of this Article; provided, however, that
bonds so owned or held which have been pledged in good faith may be regarded as
Outstanding for purposes of this paragraph if the pledgee establishes to the

                                      F-4
<PAGE>

satisfaction of the Corporate Trustee the pledgee's right to vote or give
consents with respect to such bonds and that the pledgee is not the Company or a
corporation of which the Company shall own twenty-five per centum (25 %) or more
of the outstanding voting stock. For all purposes of this Indenture, the
Corporate Trustee, the Chairman and Secretary of any meeting held pursuant to
the provisions of this Article XVIII and the Inspectors of Votes at any such
meeting shall (unless the fact is challenged at such meeting by any holder of
bonds Outstanding hereunder entitled to vote at such meeting and a contrary fact
is established) be entitled conclusively to rely upon a notification in writing
by the Company, specifying the principal amount of bonds Outstanding hereunder
owned by or held by or for the account of or for the benefit or interest of the
Company or any corporation of which the Company shall own twenty-five per centum
(25 %) or more of the outstanding voting stock, or stating that no such bonds
are so owned or held. In case the meeting shall have been called otherwise than
on the written request of the Company, the Corporate Trustee shall be entitled
conclusively to assume that none of the bonds Outstanding hereunder is so owned
or held unless a notification by the Company is furnished as in this paragraph
provided or unless the fact is challenged at such meeting by any holder of bonds
Outstanding hereunder and a contrary fact is established.

         SECTION 114. A record in duplicate of the proceedings of each meeting
of bondholders shall be prepared by the permanent Secretary of the meeting and
shall have attached thereto the original reports of the Inspectors of Votes, and
affidavits by one or more persons having knowledge of the facts showing a copy
of the notice of the meeting, and showing that said notice was mailed and
published as provided in Section 108 hereof. Such record shall be signed and
verified by the affidavits of the permanent Chairman and the permanent Secretary
of the meeting, and one duplicate thereof shall be delivered to the Company and
the other to the Corporate Trustee for preservation by the Corporate Trustee.
Any record so signed and verified shall be proof of the matters therein stated,
and if such record shall also be signed and verified by the affidavit of a duly
authorized representative of the Corporate Trustee, such meeting shall be deemed
conclusively to have been duly convened and held and such record shall be
conclusive, and any resolution or proceeding stated in such record to have been
adopted or taken, shall be deemed conclusively to have been duly adopted or
taken by such meeting. A true copy of any resolution adopted by such meeting
shall be mailed by the Corporate Trustee to each registered holder of bonds
Outstanding hereunder addressed to him at his address appearing on the registry
books and to each holder of any such bond then Outstanding hereunder payable to
bearer whose name and address appear upon the last list of bondholders furnished
to the Corporate Trustee by the Company pursuant to the provisions of Section 43
hereof, addressed to him at such address, and proof of such mailing by the
affidavit of some person having knowledge of the fact shall be filed with the
Corporate Trustee, but failure to mail copies of such resolution as aforesaid
shall not affect the validity thereof. No such resolution shall be binding until
and unless such resolution is approved by Resolution of the Board of Directors
of the Company, of which such Resolution of approval, if any, it shall be the
duty of the Company to file a copy certified by the Secretary or an Assistant
Secretary of the Company with the Corporate Trustee, but if such Resolution of
the Board of Directors of the Company is adopted and a certified copy thereof is
filed with the Corporate Trustee, the resolution so adopted by such meeting

                                      F-5
<PAGE>

shall be deemed conclusively to be binding upon the Company, the Corporate
Trustee and the holders of all bonds and coupons issued hereunder, at the
expiration of sixty (60) days after such filing, except in the event of a final
decree of a court of competent jurisdiction setting aside such resolution, or
annulling the action taken thereby in a legal action or equitable proceeding for
such purposes commenced within such sixty (60) day period; provided, however,
that no such resolution of the bondholders, or of the Company, shall in any
manner be so construed as to change or modify any of the rights, immunities, or
obligations of the Corporate Trustee without its written assent thereto.

         SECTION 115. Bonds authenticated and delivered after the date of any
bondholders' meeting may bear a notation in form approved by the Corporate
Trustee as to the action taken at meetings of bondholders theretofore held, and
upon demand of the holder of any bond Outstanding at the date of any such
meeting and presentation of his bond for the purpose at the principal office of
the Corporate Trustee, the Company shall cause suitable notation to be made on
such bond by endorsement or otherwise as to any action taken at any meeting of
bondholders theretofore held. If the Company or the Corporate Trustee shall so
determine, new bonds so modified as in the opinion of the Corporate Trustee and
the Board of Directors of the Company to conform to such bondholders' resolution
shall be prepared, authenticated and delivered, and upon demand of the holder of
any bond then Outstanding and affected thereby shall be exchanged without cost
to such bondholder for bonds then Outstanding hereunder upon surrender of such
bonds with all unmatured coupons, if any, appertaining thereto. The Company or
the Corporate Trustee may require bonds Outstanding to be presented for notation
or exchange as aforesaid if either shall see fit to do so. Instruments
supplemental to this Indenture embodying any modification or alteration of this
Indenture or of any indenture supplemental hereto made at any bondholders'
meeting and approved by Resolution of the Board of Directors of the Company, as
aforesaid, may be executed by the Corporate Trustee and the Company and upon
demand of the Corporate Trustee, or if so specified in any resolution adopted by
any such bondholders' meeting, shall be executed by the Company and the
Corporate Trustee.

         SECTION 116. (A) Anything in this Article XVIII contained to the
contrary notwithstanding, the Corporate Trustee shall receive the written
consent (in any number of instruments of similar tenor executed by bondholders
or by their attorneys appointed in writing) of the holders of sixty per centum
(60%) or more in principal amount of the bonds Outstanding hereunder, considered
as one class (or, if any action proposed to be taken shall directly affect the
holders of bonds of one or more, but less than all, series then Outstanding
hereunder, then the consent only of the holders of sixty per centum (60%) or
more in aggregate principal amount of bonds of the series so directly affected
then Outstanding hereunder, considered as one class), at the time the last such
needed consent is delivered to the Corporate Trustee, in lieu of the holding of
a meeting pursuant to this Article XVIII and in lieu of all action at such a
meeting and with the same force and effect as a resolution duly adopted in
accordance with the provisions of Section 113 hereof.

                                      F-6
<PAGE>

         (B) Instruments of consent shall be witnessed or in the alternative may
(a) have the signature guaranteed by a bank or trust company or a registered
dealer in securities, (b) be acknowledged before a Notary Public or other
officer authorized to take acknowledgments, or (c) have their genuineness
otherwise established to the satisfaction of the Corporate Trustee.

         The amount of bonds payable to bearer, and the series and serial
numbers thereof, held by a person executing an instrument of consent (or whose
attorney has executed an instrument of consent in his behalf), and the date of
his holding the same, may be proved by exhibiting the bonds to and obtaining a
certificate executed by (i) any bank or trust or insurance company organized
under the laws of the United States of America or of any State thereof, or (ii)
any trustee, secretary, administrator or other proper officer of any pension,
welfare, hospitalization or similar fund or funds, or (iii) the United States of
America, any Territory thereof, the District of Columbia, any State of the
United States, any municipality in any State of the United States or any public
instrumentality of the United States, or of any State or of any Territory, or
(iv) any other person or corporation satisfactory to the Corporate Trustee. A
bondholder in any of the foregoing categories may sign a certificate in his own
behalf.

         Each such certificate shall be dated and shall state in effect that as
of the date thereof a coupon bond or bonds bearing a specified serial number or
numbers was exhibited to the signer of such certificate. The holding by the
person named in any such certificate of any bonds specified therein shall be
presumed to continue unless (1) any certificate bearing a later date issued in
respect of the same bond shall be produced, (2) the bond specified in such
certificate (or any bond or bonds issued in exchange or substitution for such
bond) shall be produced, or (3) the bond specified in such certificate shall be
registered as to principal in the name of another holder or shall have been
surrendered in exchange or a fully registered bond registered in the name of
another holder. The Corporate Trustee may nevertheless in its discretion require
further proof in cases where it deems further proof desirable. The ownership of
registered bonds shall be proved by the registry books.

         (C) Until such time as the Corporate Trustee shall receive the written
consent of the necessary per centum in principal amount of the bonds required by
the provisions of subsection (A) above for action contemplated by such consent,
any holder of a bond, the serial number of which is shown by the evidence to be
included in the bonds the holders of which have consented to such action, may,
by filing written notice with the Corporate Trustee at its principal office and
upon proof of holding as provided in subsection (B) above, revoke such consent
so far as it concerns such bond. Except as aforesaid, any such action taken by
the holder of any bond shall be conclusive and binding upon such holder and upon
all future holders of such bond (and any bond issued in lieu thereof or
exchanged therefor), irrespective of whether or not any notation of such consent
is made upon such bond, and in any event any action taken by the holders of the

                                                                       EXHIBIT G

                             AMENDMENTS TO MORTGAGE

         (1)    The amendment of Section 5 of the Original Mortgage to delete
the second paragraph thereof and to substitute therefor three paragraphs reading
as follows:

                In the event that in any certificate filed with the Trustee in
         connection with any of the transactions referred to in clauses
         (2),(3),(5),(6) or (7) of this Section, only a part of the Cost or fair
         value of the Property Additions described in such certificate shall be
         required for the purposes of such certificate, then such Property
         Additions shall be deemed to be Funded Property only to the extent so
         required for the purpose of such certificate.

                All Funded Property that shall be abandoned, destroyed,
         released or otherwise disposed of free of the Lien of this Indenture
         shall for the purpose of Section 4 hereof be deemed Funded Property
         retired and for other purposes of this Indenture shall thereupon cease
         to be Funded Property but as in this Indenture provided may at any time
         thereafter again become Funded Property. Neither any reduction in the
         Cost or book value of property recorded in the plant account of the
         Company, nor the transfer of any amount appearing in such account to
         intangible and/or adjustment accounts, otherwise than in connection
         with actual retirements of physical property so abandoned, destroyed,
         released or disposed of, and otherwise than in connection with the
         removal of such property in its entirety from plant account, shall be
         deemed to constitute a retirement of Funded Property.

                The Company may make allocations, on a pro-rata or other
         reasonable basis, for the purpose of determining the extent to which
         fungible properties, reflected in the same generic class of property in
         the Company's books of account and not otherwise specifically
         identified, constitute Funded Property or Funded Property retired.

         (2) The deletion of Section 7 of the Original Mortgage in its entirety
and the substitution therefor of a new Section 7 reading as follows:

         SECTION 7. The term "Net Earning Certificate" shall mean a certificate
signed and verified by the President or a Vice-President and the Treasurer or an
Assistant Treasurer of the Company, stating

                (A)   the Net Earnings of the Company for a period of twelve
         (12) consecutive calendar months within the eighteen (18) calendar
         months immediately preceding the first day of the month in which the
         application for the authentication and delivery under this Indenture of
         bonds then applied for is made, specifying;

                      (1)   its operating revenues (which may include revenues
                subject when collected or accrued to possible refund at a future
                date), with the principal divisions thereof;

                      (2)   its operating expenses, with the principal divisions
                thereof;

<PAGE>

                      (3)   the amount remaining after deducting such operating
                expenses from such operating revenues;

                      (4)   its rental expenses for plants or systems not
                otherwise deducted from revenues or from other income in such
                certificate;

                      (5)   the balance remaining after deducting such rental
                expenses from the amount required to be stated in such
                certificate by clause (3) of this Section;

                      (6)   its rental revenues from plants or systems not
                otherwise included in revenues, or in other income (net) in such
                certificate;

                      (7)   the sum of the amounts required to be stated in such
                certificate by clauses (5) and (6) of this Section;

                      (8)   its other income (net), which may include any
                portion of the allowance for funds used during construction or
                any portion of the allowance for funds used for conservation
                expenditures (or any analogous amount), in either case, which is
                not included in "other income" (or any analogous item) in the
                Company's books of account;

                      (9)   the sum of the amounts required to be stated in such
                certificate by clauses (7) and (8) of this Subdivision (A);

                      (10)  the amount, if any, by which the aggregate of (a)
                such other income (net) and (b) that portion of the amount
                required to be stated in such certificate by clause (7) of this
                Section which, in the opinion of the signers, is directly
                derived from the operations of the property (other than paving,
                grading and other improvements to, under or upon public high-
                ways, bridges, parks or other public properties of analogous
                character) not subject to the Lien of this Indenture at the date
                of such certificate, exceeds twenty per centum (20%) of the sum
                required to be stated by clause (9) of this Section;

                      (11)  the Net Earnings of the Company for such period of
                twelve (12) consecutive calendar months (being the amount
                remaining after deducting in such certificate the amount
                required to be stated by clause (10) of this Section from the
                sum required to be stated by clause (9) of this Section);

                (B)   the Annual Interest Requirements, being the interest
         requirements for twelve (12) months upon:

                      (i)   all bonds Outstanding hereunder at the date of
                such certificate, except any for the refunding of which the
                bonds applied for are to be issued;

                      (ii)  all bonds then applied for in pending applica-
                tions, including the application in connection with which such
                certificate is made;

                                      G-2
<PAGE>

                      (iii) all bonds deposited with or held in pledge by
                the Corporate Trustee under any of the provisions of this
                Indenture under conditions such that they may be issued or
                reissued;

                      (iv)  all Prior Lien Bonds which will be Outstanding
                immediately after the authentication of the bonds then applied
                for in pending applications, including the application in
                connection with which such certificate is made; and

                      (v) the principal amount of all other indebtedness
                (except indebtedness for the purchase, payment or redemption
                of which moneys in the necessary amount shall have been
                deposited with or be held by the Corporate Trustee or the
                trustee or other holder of a lien prior hereto with
                irrevocable direction so to apply the same; provided that, in
                the case of redemption, the notice required therefor shall
                have been given or have been provided for to the satisfaction
                of the Corporate Trustee), outstanding in the hands of the
                public on the date of such certificate and secured by lien
                prior or equal to the Lien of this Indenture upon property of
                the Company subject to the Lien of this Indenture, if said
                indebtedness has been assumed by the Company or if the Company
                customarily pays the interest upon the principal thereof.

                In calculating such Net Earnings, all the Company's expenses
         for taxes (other than income, profits and other taxes measured by, or
         dependent on, net income), assessments, rentals, insurance and expenses
         for current repairs and maintenance, shall be included in its operating
         expenses, or otherwise deducted from its revenues or other income;
         provided, however, that there shall not be required to be so included
         or deducted (A) any provision for renewal, replacement, depreciation,
         depletion or retirement of property, or for amortization, (B) expenses
         or provisions for interest on any of its indebtedness or for the
         amortization of debt discount, expense or loss on reacquired debt for
         any maintenance and replacement, improvement or sinking fund or other
         device for the retirement of any indebtedness, (C) expenses or
         provisions for any non-recurring charge to income of whatever kind or
         nature (including without limitation the recognition of expense due to
         the non-recoverability of investment), whether or not recorded as an
         extraordinary item in the Company's books of account or (D) provisions
         for any refund of revenues previously collected or accrued subject to
         possible refund.

                In calculating such Annual Interest Requirements (A) if any
         bonds issued hereunder, Prior Lien Bonds and/or other indebtedness
         bears interest at a variable rate or rates, the Annual Interest
         Requirements thereon shall be determined by reference to the rate or
         rates in effect on the date next preceding the date of the initial
         authentication and delivery of the bonds then applied for in the
         application in connection with which the Net Earning Certificate is
         made, (B) if such bonds then applied for and/or any bonds applied for
         in any other pending application are to bear interest at a variable
         rate or rates, the Annual Interest Requirements thereon shall be
         determined by reference to the rate or rates to be in effect at the
         time of the initial authentication and delivery thereof, and (C) the
         Annual Interest Requirements on bonds issued or to be issued hereunder,
         Prior Lien Bonds and any other indebtedness shall be determined by
         reference to the rate or rates at which such obligations are stated by
         their terms to bear simple interest, without regard to the effective

                                      G-3
<PAGE>

         interest cost to the Company of such obligations and without regard to
         the stated interest rate or rates upon, or the effective interest cost
         to the Company of, other obligations for which such obligations are or
         are to be pledged or otherwise delivered as security.

                If any of the property of the Company owned by it at the time
         of the making of any Net Earning Certificate shall have been acquired
         during or after any period for which Net Earnings of the Company are to
         be computed, the Net Earnings of such property (computed in the manner
         in this Section provided for the computation of the Net Earnings of the
         Company) during such period or such part of such period as shall have
         preceded the acquisition thereof, to the extent that the same have not
         otherwise been included and unless such property shall have been
         acquired in exchange or substitution for property the earnings of which
         have been included, may, at the option of the Company, be included in
         the Net Earnings of the Company for all purposes of this Indenture.

                Net Earnings, whether of the Company, or of a particular
         property, shall be determined in accordance with accepted principles of
         accounting.

         (3)    (a)   The amendment of Section 25 of the Original Mortgage to
delete the words "sixty per centum (60%)" from the first sentence thereof and to
substitute therefor the words "seventy per centum (70%)";

                (b)   The amendment of Section 26 of the Original Mortgage,

                      (i)   to delete the words "ten sixths (10/6)" from the

                "ten sevenths (10/7)";

                      (ii)  to delete the words "sixty per centum (60%)"
                from each of clause (c) and clause (d) of the fourth paragraph
                thereof and to substitute therefor the words "seventy per
                centum (70%)";

                      (iii) to insert immediately following the words
                "fifteen per centum of after clause (d) in the fourth
                paragraph thereof the words "the sum of (1)" and to insert at
                the end of such paragraph the words "and (2) all Prior Lien
                Bonds to be Outstanding upon the granting of such
                application." and

                      (iv)  to delete the words "fifty per centum (50%)"
                from the fourth paragraph thereof and to substitute therefor
                the words "seventy per centum (70%)".

                (c)   The amendment of Section 59 of the Original Mortgage,

                      (i)   to insert the phrase "ten-sevenths (10/7) of" at the
                beginning of clause (c) of subdivision (4) of the first
                paragraph thereof;

                      (ii)  to delete the words "sixty per centum (60%)"
                from the proviso to subdivision (4) of the first paragraph
                thereof and to substitute therefor the words "seventy per
                centum (70%)"; and

                                      G-4
<PAGE>

                      (iii) to delete the words "sixty per centum (60%)"
                from the second and third paragraphs thereof and to substitute
                therefor, in each case, the words "seventy per centum (70%)".

                (d)   The amendment of Section 61 of the Original Mortgage

                      (i)   to insert the words "ten sevenths (10/7) of"
                immediately before the words "the principal amount ..." in
                subdivision (2) of the first paragraph thereof; and

                      (ii)  to delete the words "sixty per centum (60%)"
                from the second and third paragraphs thereof and to substitute
                therefor, in each case, the words "seventy per centum (70%)";

         (4)    The amendment in its entirety of Section 38 of the Original
Mortgage to read as set forth below, and the deletion of all references in the
Mortgage to Section 38 to the extent such references are rendered nugatory by
such amendment:

                      Section 38. The Company will cause (or, with respect
                to property owned in common with others, make reasonable
                effort to cause) the Mortgaged and Pledged Property, as an
                operating system or systems, to be maintained and kept in good
                repair, working order and condition and will cause (or, with
                respect to property owned in common with others, make
                reasonable effort to cause) to be made such repairs, renewals
                and replacements thereof as, in the judgment of the Company,
                may be necessary in order that the operation of the Mortgaged
                and Pledged Property, considered as an operating system or
                systems, may be conducted in accordance with common industry
                practice; provided, however, that nothing in this Section
                shall prevent the Company from discontinuing, or causing or
                consenting to the discontinuance of, the operation and
                maintenance of any of its properties if such discontinuance
                is, in the judgment of the Company, desirable in the conduct
                of its business.

                After the effectiveness of such amendment, among other things,
         Funded Property shall not include any Property Additions that have at
         any time been deemed to have been made the basis of a credit under the
         provisions of Section 38, as in effect prior to such amendment, or
         substituted for other Property Additions that have so been deemed to
         have been made the basis of such a credit.

         (5)    (a)   The amendment of Section 85 of the Mortgage, as amended,
to add thereto a second paragraph reading as follows:

                      Nothing in this Indenture shall prevent any consolidation
                or merger after the consummation of which the
                Company would be the surviving or resulting corporation or any
                conveyance, transfer or lease of any part of the Mortgaged and
                Pledged Property which does not constitute the entirety, or
                substantially the entirety, thereof.

                ; and

<PAGE>

                (b)   The  amendment of Section 87 of the Original Mortgage to
         add  thereto a second  paragraph reading as follows:

                      In case the Company shall enter into any transaction
                contemplated in the second paragraph of Section 85 hereof,
                unless an indenture executed and delivered by the Company and
                the Trustee shall otherwise provide, this Indenture shall not
                become or be a lien upon any of the properties or franchises
                acquired by the Company in or as a result of such transaction
                or upon any improvements, extensions or additions thereto or
                any renewals or replacements thereof.

         (6)    The amendment of Section 102 of the Original Mortgage to insert
immediately after the first paragraph thereof a new paragraph reading as
follows:

                      (A) So long as no event which is, or after notice or
                lapse of time, or both, would become, a Completed Default (as
                defined in Section 65 hereof) shall have occurred and be
                continuing, if the Company shall have delivered to the Trustee
                (i) an instrument executed by order of its Board of Directors
                and duly acknowledged by proper officers of the Company
                appointing a successor Corporate Trustee, Individual Trustee
                or other 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, such
                trustee shall be deemed to have resigned as contemplated in
                Section 100, and such successor trustee shall be deemed to
                have been appointed pursuant to the first paragraph of this
                Section, all as of such date, and all other provisions of this
                Article shall be applicable to such resignation, appointment
                and acceptance except to the extent inconsistent with this
                paragraph

         (7)    The amendment of Section 120 of the Original Mortgage to read as
follows:

                SECTION 120. Anything in this Indenture to the contrary
         notwithstanding, without the consent of any holders of bonds, the
         Company and the Trustees, at any time and from time to time, may enter
         into one or more indentures supplemental hereto, in form satisfactory
         to the Trustees, for any of the following purposes:

                      (a)   to evidence the succession of another corporation to
                the Company and the assumption by any such successor of the
                covenants of the Company herein and in the bonds, all as
                provided in Article XV hereof, or

                      (b)   to add one or more covenants of the Company or
                other provisions for the benefit of all holders of the bonds
                or for the benefit of the holders of, or to remain in effect
                only so long as there shall be Outstanding, bonds of one or
                more specified series, and to make the occurrence of a default
                in the performance of any of such additional covenants an
                additional "Completed Default" under Section 65 permitting the
                enforcement of all or any of the several remedies provided in
                this Indenture, as herein set forth; provided, however, that
                in respect of any such additional covenant, such supplemental
                indenture may provide for a particular period of grace after
                default (which period may be shorter or longer than those
