                                 (JUNE 30, 2002)

                                    ARTICLE I

                                  Stockholders

         Section 1.1. Annual Meetings. An annual meeting of stockholders shall
be held for the election of directors at such date, time and place, either
within or without the State of California, as may be designated by resolution of
the Board of Directors from time to time. Any other proper business may be
transacted at the annual meeting.

         Section 1.2. Special Meetings. Special meetings of stockholders for any
purpose or purposes may be called at any time by the Board of Directors, or by a
committee of the Board of Directors which has been duly designated by the Board
of Directors and whose powers and authority, as expressly provided in a
resolution of the Board of Directors, include the power to call such meetings,
but such special meetings may not be called by any other person or persons.

         Section 1.3. Notice of Meetings. Whenever stockholders are required or
permitted to take any action at a meeting, a written notice of the meeting shall
be given which shall state the place, date and hour of the meeting, and, in the
case of a special meeting, the purpose or purposes for which the meeting is
called. Unless otherwise provided by law, the certificate of incorporation or
these bylaws, the written notice of any meeting shall be given not less than ten
nor more than sixty days before the date of the meeting to each stockholder
entitled to vote at such meeting. If mailed, such notice shall be deemed to be
given when deposited in the mail, postage prepaid, directed to the stockholder
at his, her or its address as it appears on the records of the corporation.

         Section 1.4. Adjournments. Any meeting of stockholders, annual or
special, may adjourn from time to time to reconvene at the same or some other
place, and notice need not be given of any such adjourned meeting if the time
and place thereof are announced at the meeting at which the adjournment is
taken. At the adjourned meeting the corporation may transact any business which
might have been transacted at the original meeting. If the adjournment is for
more than thirty days, or if after the adjournment a new record date is fixed
for the adjourned meeting, a notice of the adjourned meeting shall be given to
each stockholder of record entitled to vote at the meeting.



         Section 1.5. Quorum. Except as otherwise provided by law, the
certificate of incorporation or these bylaws, at each meeting of stockholders
the presence in person or by proxy of the holders of shares of stock having a
majority of the votes which could be cast by the holders of all outstanding
shares of stock entitled to vote at the meeting shall be necessary and
sufficient to constitute a quorum. In the absence of a quorum, the stockholders
so present may, by majority vote, adjourn the meeting from time to time in the
manner provided in Section 1.4 of these bylaws until a quorum shall attend.
Shares of its own stock belonging to the corporation or to another corporation,
if a majority of the shares entitled to vote in the election of directors of
such other corporation is held, directly or indirectly, by the corporation,
shall neither be entitled to vote nor be counted for quorum purposes; provided,
however, that the foregoing shall not limit the right of the corporation to vote
stock, including but not limited to its own stock, held by it in a fiduciary
capacity.

         Section 1.6. Organization. Meetings of stockholders shall be presided
over by the Chairman of the Board, if any, or in his or her absence by the Vice
Chairman of the Board, if any, or in his or her absence by the President, or in
his or her absence by a Vice President, or in the absence of the foregoing
persons by a chairman designated by the Board of Directors, or in the absence of
such designation by a chairman chosen at the meeting. The Secretary shall act as
secretary of the meeting, but in his or her absence the chairman of the meeting
may appoint any person to act as secretary of the meeting.

         Section 1.7. Voting; Proxies. Except as otherwise provided by the
certificate of incorporation, each stockholder entitled to vote at any meeting
of stockholders shall be entitled to one vote for each share of stock held by
him, her or it which has voting power upon the matter in question. Each
stockholder entitled to vote at a meeting of stockholders may authorize another
person or persons to act for him, her or it by proxy, but no such proxy shall be
voted or acted upon after three years from its date, unless the proxy provides
for a longer period. A duly executed proxy shall be irrevocable if it states
that it is irrevocable and if, and only as long as, it is coupled with an
interest sufficient in law to support an irrevocable power. A stockholder may
revoke any proxy which is not irrevocable by attending the meeting and voting in
person or by filing an instrument in writing revoking the proxy or another duly
executed proxy bearing a later date with the Secretary of the corporation.
Voting at meetings of stockholders need not be by written ballot and need not be
conducted by inspectors of election unless so determined by the holders of
shares of stock having a majority of the votes which could be cast by the
holders of all outstanding shares of stock entitled to vote thereon which are
present in person or by proxy at such meeting. At all meetings of stockholders
for the election of directors, a plurality of the votes cast shall be sufficient
to elect. All other elections and questions shall, unless otherwise provided by
law, the certificate of incorporation or these bylaws, be decided by the vote of
the holders of shares of stock

                                       2



having a majority of the votes which could be cast by the holders of all shares
of stock entitled to vote thereon which are present in person or represented by
proxy at the meeting.

         Section 1.8. Fixing Date for Determination of Stockholders of Record.
In order that the corporation may determine the stockholders entitled to notice
of or to vote at any meeting of stockholders or any adjournment thereof, or to
express consent to corporate action in writing without a meeting, or entitled to
receive payment of any dividend or other distribution or allotment of any
rights, or entitled to exercise any rights in respect of any change, conversion
or exchange of stock or for the purpose of any other lawful action, the Board of
Directors may fix a record date, which record date shall not precede the date
upon which the resolution fixing the record date is adopted by the Board of
Directors and which record date: (1) in the case of determination of
stockholders entitled to vote at any meeting of stockholders or adjournment
thereof, shall, unless otherwise required by law, not be more than sixty nor
less than ten days before the date of such meeting; (2) in the case of
determination of stockholders entitled to express consent to corporate action in
writing without a meeting, shall not be more than ten days from the date upon
which the resolution fixing the record date is adopted by the Board of Directors
and (3) in the case of any other action, shall not be more than sixty days prior
to such other action. If no record date is fixed: (1) the record date for
determining stockholders entitled to notice of or to vote at a meeting of
stockholders shall be at the close of business on the day next preceding the day
on which notice is given, or, if notice is waived, at the close of business on
the day next preceding the day on which the meeting is held; (2) the record date
for determining stockholders entitled to express consent to corporate action in
writing without a meeting when no prior action of the Board of Directors is
required by law, shall be the first date on which a signed written consent
setting forth the action taken or proposed to be taken is delivered to the
corporation in accordance with applicable law, or, if prior action by the Board
of Directors is required by law, shall be at the close of business on the day on
which the Board of Directors adopts the resolution taking such prior action and
(3) the record date for determining stockholders for any other purpose shall be
at the close of business on the day on which the Board of Directors adopts the
resolution relating thereto. A determination of stockholders of record entitled
to notice of or to vote at a meeting of stockholders shall apply to any
adjournment of the meeting; provided, however that the Board of Directors may
fix a new record date for the adjourned meeting.

         Section 1.9. List of Stockholders Entitled to Vote. The Secretary shall
prepare and make, at least ten days before every meeting of stockholders, a
complete list of the stockholders entitled to vote at the meeting, arranged in
alphabetical order, and showing the address of each stockholder and the number
of shares registered in the name of each stockholder. Such list shall be open to
the examination of any stockholder, for any

                                       3



purpose germane to the meeting, during ordinary business hours, for a period of
at least ten days prior to the meeting, either at a place within the city where
the meeting is to be held, which place shall be specified in the notice of the
meeting, or, if not so specified, at the place where the meeting is to be held.
The list shall also be produced and kept at the time and place of the meeting
during the whole time thereof and may be inspected by any stockholder who is
present. Upon the willful neglect or refusal of the directors to produce such a
list at any meeting for the election of directors, they shall be ineligible for
election to any office at such meeting. The stock ledger shall be the only
evidence as to who are the stockholders entitled to examine the stock ledger,
the list of stockholders or the books of the corporation, or to vote in person
or by proxy at any meeting of stockholders.

         Section 1.10. Action By Consent of Stockholders. Unless otherwise
restricted by the certificate of incorporation, any action required or permitted
to be taken at any annual or special meeting of the stockholders may be taken
without a meeting, without prior notice and without a vote, if a consent in
writing, setting forth the action so taken, shall be signed by the holders of
outstanding stock having not less than the minimum number of votes that would be
necessary to authorize or take such action at a meeting at which all shares
entitled to vote thereon were present and voted. Prompt notice of the taking of
the corporate action without a meeting by less than unanimous written consent
shall be given to those stockholders who have not consented in writing.

                                   ARTICLE II

consist of one or more members, the number thereof to be determined from time to
time by resolution of the Board of Directors. Directors need not be
stockholders.

         Section 2.2. Election; Resignation; Removal; Vacancies. The Board of
Directors shall initially consist of the persons named as directors in the
certificate of incorporation, or a subsequent action of the incorporator, and
each director so elected shall hold office until the first annual meeting of
stockholders or until his or her successor is elected and qualified. At the
first annual meeting of stockholders and at each annual meeting thereafter, the
stockholders shall elect directors, each of whom shall hold office for a term of
one year or until his or her successor is elected and qualified. Any director
may resign at any time upon written notice to the corporation. Any newly created
directorship or any vacancy occurring in the Board of Directors for any cause
may be filled by a majority of the remaining members of the Board of Directors,
although such majority is less than a quorum, or by a plurality of the votes
cast at a meeting of

                                       4



stockholders, and each director so elected shall hold office until the
expiration of the term of office of the director whom he or she has replaced or
until his or her successor is elected and qualified.

         Section 2.3. Regular Meetings. Regular meetings of the Board of
Directors may be held at such places within or without the State of
<<State Incorp>> and at such times as the Board of Directors may from time to
time determine, and if so determined, notices thereof need not be given.

         Section 2.4. Special Meetings. Special meetings of the Board of
Directors may be held at any time or place within or without the State of
<<State Incorp>> whenever called by the President, any Vice President, the
Secretary, or by any member of the Board of Directors. Notice of a special
meeting of the Board of Directors shall be given by the person or persons
calling the meeting at least twenty-four hours before the special meeting.

         Section 2.5. Telephonic Meetings Permitted. Members of the Board of
Directors, or any committee designated by the Board of Directors, may
participate in a meeting thereof by means of conference telephone or similar
communications equipment in which all persons participating in the meeting can
hear each other, and participation in the meeting pursuant to this bylaw shall
constitute presence in person at such meeting.

         Section 2.6. Quorum; Vote Required for Action. At all meetings of the
Board of Directors a majority of the whole Board of Directors shall constitute a
quorum for the transaction of business. Except in cases in which the certificate
of incorporation or these bylaws otherwise provide, the vote of a majority of
the directors present at a meeting at which a quorum is present shall be the act
of the Board of Directors.

         Section 2.7. Organization. Meetings of the Board of Directors shall be
presided over by the Chairman of the Board, if any, or in his or her absence by
the Vice Chairman of the Board, if any, or in his or her absence by the
President, or in their absence by a chairman chosen at the meeting. The
Secretary shall act as secretary of the meeting, but in his or her absence the
chairman of the meeting may appoint any person to act as secretary of the
meeting.

         Section 2.8. Informal Action by Directors. Unless otherwise restricted
by the certificate of incorporation or these bylaws, any action required or
permitted to be taken at any meeting of the Board of Directors, or of any
committee thereof, may be taken without a meeting if all members of the Board of
Directors or such committee, as the case may be, consent thereto in writing, and
the writing or writings are filed with the

                                       5



minutes of proceedings of the Board of Directors or such committee.

                                   ARTICLE III

                                   Committees

         Section 3.1. Committees. The Board of Directors may, by resolution
passed by a majority of the whole Board of Directors, designate one or more
committees, each committee to consist of one or more of the directors of the
corporation. The Board of Directors may designate one or more directors as
alternate members of any committee, who may replace any absent or disqualified
member at any meeting of the committee. In the absence or disqualification of a
member of the committee, the member or members thereof present at any meeting
and not disqualified from voting, whether or not he, she or they constitute a
quorum, may unanimously appoint another member of the Board of Directors to act
at the meeting in place of any such absent or disqualified member. Any such
committee, to the extent permitted by law and to the extent provided in the
resolution of the Board of Directors, shall have and may exercise all the powers
and authority of the Board of Directors in the management of the business and
affairs of the corporation, and may authorize the seal of the corporation (if
any) to be affixed to all papers which may require it.

         Section 3.2. Committee Rules. Unless the Board of Directors otherwise
provides, each committee designated by the Board of Directors may make, alter

each committee shall conduct its business in the same manner as the Board of
Directors conducts its business pursuant to Article III of these bylaws.

                                   ARTICLE IV

                                    Officers

         Section 4.1. Executive Officers; Election; Qualifications; Term of
Office; Resignation; Removal; Vacancies. The Board of Directors shall elect a
President and Secretary, and it may, if it so determines, choose a Chairman of
the Board and a Vice Chairman of the Board from among its members. The Board of
Directors may also choose one or more Vice Presidents, one or more Assistant
Secretaries, a Treasurer and one or more Assistant Treasurers. Each such officer
shall hold office until the first meeting of the Board of Directors after the
annual meeting of stockholders next succeeding his or her election, and until
his or her successor is elected and qualified or until his or her earlier
resignation or removal. Any officer may resign at any time upon written notice
to the corporation. The Board of Directors may remove any officer with

                                       6



or without cause at any time, but such removal shall be without prejudice to the
contractual rights of such officer, if any, with the corporation. Any number of
offices may be held by the same person. Any vacancy occurring in any office of
the corporation by death, resignation, removal or otherwise may be filled for
the unexpired portion of the term by the Board of Directors at any regular or
special meeting.

         Section 4.2. Powers and Duties of Executive Officers. The officers of
the corporation shall have such powers and duties in the management of the
corporation as may be prescribed by the Board of Directors and, to the extent

officer, agent or employee to give security for the faithful performance of his
or her duties.

                                   ARTICLE V

have a certificate signed by or in the name of the corporation by the Chairman
or a Vice Chairman of the Board of Directors, if any, or the President or a Vice
President, and by the Treasurer or an Assistant Treasurer, or the Secretary or
an Assistant Secretary, of the corporation, certifying the number of shares
owned by him, her or it in the corporation. Any of or all the signatures on the
certificate may be a facsimile. In case any officer, transfer agent or registrar
who has signed or whose facsimile signature has been placed upon a certificate
shall have ceased to be such officer, transfer agent or registrar before such
certificate is issued, it may be issued by the corporation with the same effect
as if he or she were such officer, transfer agent or registrar at the date of
issue.

         Section 5.2. Lost, Stolen or Destroyed Stock Certificates; Issuance of
New Certificates. The corporation may issue a new certificate of stock in the
place of any certificate theretofore issued by it, alleged to have been lost,
stolen or destroyed, and the corporation may require the owner of the lost,
stolen or destroyed certificate, or his, her or its legal representative, to
give the corporation a bond sufficient to indemnify it against any claim that
may be made against it on account of the alleged loss, theft or destruction of
any such certificate or the issuance of such new certificate.

         Section 6.1. Right to Indemnification. The corporation shall indemnify
and hold harmless, to the fullest extent permitted by applicable law as it
presently exists or may hereafter be amended, any person who was or is made or
is threatened to be made a party or is otherwise involved in any action, suit or
proceeding, whether civil, criminal, administrative or investigative (a
"proceeding") by reason of the fact that he or she, or a person for whom he or
she is the legal representative, is or was a director, officer, employee or
agent of the corporation or is or was serving at the request of the corporation
as a director, officer, employee or agent of another corporation or of a
partnership, joint venture, trust, enterprise or non-profit entity, including
service with respect to employee benefit plans, against all liability and loss
suffered and expenses reasonably incurred by such person. The corporation shall
be required to indemnify a person in connection with a proceeding initiated by
such person only if the proceeding was authorized by the Board of Directors of
the corporation.

         Section 6.2. Repayment of Expenses. The corporation shall pay the
expenses incurred in defending any proceeding in advance of its final
disposition; provided, however, that the payment of expenses incurred by a
director or officer in advance of the final disposition of the proceeding shall
be made only upon receipt of an undertaking by the director or officer to repay
all amounts advanced if it should be ultimately determined that the director or
officer is not entitled to be indemnified under this Article or otherwise.

         Section 6.3. Claims. If a claim for indemnification or payment of
expenses under this Article is not paid in full within sixty days after a
written claim therefor has been received by the corporation the claimant may
file suit to recover the unpaid amount of such claim and, if successful in whole
or in part, shall be entitled to be paid the expense of prosecuting such claim.
In any such action the corporation shall have the burden of proving that the
claimant was not entitled to the requested indemnification or payment of
expenses under applicable law.

         Section 6.4. Non-Exclusivity of Rights. The rights conferred on any
person by this Article VI shall not be exclusive of any other rights which such
person may have or hereafter acquire under any statute, provision of the
certificate or incorporation, these bylaws, agreement, vote of stockholders or
disinterested directors or otherwise.

         Section 6.5. Other Indemnification. The corporation's obligation, if
any, to indemnify any person who was or is serving at its request as a director,
officer,

                                       8



employee or agent of another corporation, partnership, joint venture, trust,
enterprise or non-profit entity shall be reduced by any amount such person may
collect as indemnification from such other corporation, partnership, joint
venture, trust, enterprise or non-profit entity.

         Section 6.6. Amendment or Repeal. Any repeal or modification of the
foregoing provisions of this Article VI shall not adversely affect any right or
protection hereunder of any person in respect of any act or omission occurring
prior to the time of such repeal or modification.

                                  ARTICLE VII

         Section 7.2. Seal. The Board of Directors shall determine whether or
not the corporation shall have a corporate seal. The corporate seal (if any)
shall have the name of the corporation inscribed thereon and shall be in such
form as may be approved from time to time by the Board of Directors.

         Section 7.3. Waiver of Notice of Meetings of Stockholders, Directors
and Committees. Any written waiver of notice, signed by the person entitled to
notice, whether before or after the time stated therein, shall be deemed
equivalent to notice. Attendance of a person at a meeting shall constitute a
waiver of notice of such meeting, except when the person attends a meeting for
the express purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or
convened. Neither the business to be transacted at, nor the purpose of any
regular or special meeting of the stockholders, directors, or members of a
committee of directors need be specified in any written waiver of notice.

         Section 7.4. Interested Directors; Quorum. No contract or transaction
between the corporation and one or more of its directors or officers, or between
the corporation and any other corporation, partnership, association or other
organization in which one or more of its directors or officers are directors or
officers, or have a financial interest, shall be void or voidable solely for
this reason, or solely because the director or officer is present at or
participates in the meeting of the Board of Directors or committee thereof which
authorizes the contract or transaction, or solely because his, her or their
votes are counted for such purpose, if: (1) the material facts as to his, her or
their relationship or interest and as to the contract or transaction are
disclosed or are known to the Board of

                                       9



Directors or the committee, and the Board of Directors or committee in good
faith authorizes the contract or transaction by the affirmative votes of a
majority of the disinterested directors, even though the disinterested directors
be less than a quorum; or (2) the material facts as to his, her or their
relationship or interest and as to the contract or transaction are disclosed or
are known to the stockholders entitled to vote thereon, and the contract or
transaction is specifically approved in good faith by vote of the stockholders
or (3) the contract or transaction is fair as to the corporation as of the time
it is authorized, approved or ratified, by the Board of Directors, a committee
thereof, or the stockholders. Common or interested directors may be counted in
determining the presence of a quorum at a meeting of the Board of Directors or
of a committee which authorizes the contract or transaction. Nothing in this
Section 7.4 shall be construed to imply that any contract or transaction between
the corporation and Northern States Power Company ("NSP"), or between the
corporation and any other corporation that is a direct or indirect wholly-owned
subsidiary of NSP, shall be void or voidable, whether or not such contract or
transaction complies with the requirements of clauses (1), (2) or (3) of the
immediately preceding sentence.

         Section 7.5. Form of Records. Any records maintained by the corporation
in the regular course of its business, including its stock ledger, books of
account and minute books, may be kept on, or be in the form of, punch cards,
magnetic tape, photographs, microphotographs or any other information storage
device, provided that the records so kept can be converted into clearly legible
form within a reasonable time. The corporation shall so convert any records so
kept upon the request of any person entitled to inspect the same.

         Section 7.6. Amendment of Bylaws. These bylaws may be altered or
repealed, and new bylaws made, by the Board of Directors, but the stockholders
may make additional bylaws and may alter and repeal any bylaws whether adopted
by them or otherwise.

                                       10
