         1.       REGISTERED AND OTHER OFFICES.

                  1.1      REGISTERED OFFICE. The registered office of the
Corporation shall be in the City of Santa Fe, County of Santa Fe, State of New
Mexico.

                  1.2      OTHER OFFICES. The Corporation may also have offices
at such other places both within and without the State of New Mexico as the
Board of Directors of the Corporation ("Board") may from time to time determine
or the business of the Corporation may require.

         2.       SHAREHOLDERS.

                  2.1      ANNUAL MEETING. The annual meeting of the
shareholders of the Corporation, for the election of directors, the
consideration of financial statements and other reports, and the transaction of
such other business as may properly be brought before such meeting, shall be
held at such time, at such place and on such date as may be designated by the
Board. In the event the annual meeting is not held or if directors are not
elected at the annual meeting, a special meeting may be called and held for that
purpose.

                  2.2      SPECIAL MEETING. Special meetings of the
shareholders, for any purpose or purposes, may be called at any time by the
Board or the Chairman.

                  2.3      PLACE OF MEETING. All meetings of the shareholders
for the election of directors shall be held at such place either within or
without the State of New Mexico as shall be designated from time to time by the
Board and stated in the notice of the meeting. Meetings of shareholders for any
other purpose may be held at such time and place either within or without the
State of New Mexico as shall be stated in the notice of such meeting.

                  2.4      NOTICE OF MEETINGS AND ADJOURNED MEETINGS. Written
notice of the annual meeting or a special meeting stating 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, shall be given to each shareholder
entitled to vote at such meeting not fewer than 10 nor more than 60 days before
the date of the meeting. When a meeting is adjourned to another time or place,
notice need not be given of the adjourned meeting if the time and place thereof
are announced at the meeting at which the adjournment is taken. At the adjourned
meeting, the shareholders may transact any business which might have been
transacted at the original meeting. If the adjournment is for more than 30 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 shareholder of
record entitled to vote at the meeting.

                  2.5      SHAREHOLDERS' LIST. The officer who has charge of the
stock ledger of the Corporation shall prepare and make, at least 10 days before
every meeting of shareholders, a



complete list of the shareholders entitled to vote at the meeting, arranged in
alphabetical order and showing the address of each shareholder and the number of
shares registered in the name of each shareholder. Such list shall be open to
the examination of any shareholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least 10 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 shareholder who is present.

                  2.6      QUORUM AND ADJOURNMENT. At any meeting of
shareholders, the holders of a majority of the issued and outstanding shares of
stock entitled to vote present in person or represented by proxy shall
constitute a quorum. If, however, such quorum shall not be present or
represented at any meeting of the shareholders, the chairman of the meeting or a
majority of the shareholders who are entitled to vote at the meeting, present in
person or represented by proxy, shall have power to adjourn the meeting from
time to time, without notice other than announcement at the meeting, until a
quorum shall be present or represented.

                  2.7      VOTING. When a quorum is present or represented at
any meeting, the vote of the holders of a majority of the shares of stock having
voting power present in person or represented by proxy shall decide any question
brought before such meeting, unless the question is one upon which by express
provision of the New Mexico Business Corporation Act or of the Articles of
Incorporation or of these Bylaws a different vote is required, in which case
such express provision shall govern and control the decision of such question.
At each meeting of the shareholders, each shareholder shall, unless otherwise
provided by the Articles of Incorporation, be entitled to one vote in person or
by proxy for each share of stock held by the shareholder which has voting power
upon the matter in question.

                  2.8      PROXIES. No proxy shall be voted after three years
from its date, unless the proxy provides for a longer period.

                  2.9      ACTION OF SHAREHOLDERS WITHOUT A MEETING. Whenever
the vote of shareholders at a meeting thereof is required or permitted to be
taken for or in connection with any corporate action, whether by any provision
of the New Mexico Business Corporation Act or of the Articles of Incorporation
or these Bylaws or otherwise, such corporate action may be taken without a
meeting if a consent in writing, setting forth the action so taken, is signed by
all of the shareholders entitled to vote with respect to the subject matter
thereof. Such consent has the same effect as a unanimous vote of shareholders,
and may be stated as such in any articles or document filed with the commission
under the New Mexico Business Corporation Act..

         3.       DIRECTORS.

                  3.1      NUMBER OF DIRECTORS. The business affairs of the
Corporation shall be managed by its Board. The number of directors which shall
constitute the whole Board shall be as fixed by resolution of the Board from
time to time, except as otherwise provided by the Articles of Incorporation.

                                       -2-



                  3.2      ELECTION OF DIRECTORS. Directors shall be elected at
the annual meeting of shareholders, or if not so elected, at a special meeting
of shareholders called for that purpose; provided, that if the Corporation has
no shareholders, directors may be appointed by the incorporators. At any
meeting of shareholders at which directors are to be elected, only persons
nominated as candidates shall be eligible for election, and the candidates
receiving the greatest number of votes shall be elected.

                  3.3      TERM. Each director shall hold office until the next
annual meeting of the shareholders and until the director's successor has been
elected and qualified or until the director's earlier resignation, removal from
office, or death.

                  3.4      REMOVAL. Any director or the entire Board may be
removed, with or without cause, at any time, by the holders of a majority of the
shares then entitled to vote at an election of directors at a special meeting of
the shareholders called for the purpose.

                  3.5      VACANCIES. Any vacancy occurring on the Board for any
reason, including, but not limited to, the resignation, removal, or death of a
director, or an increase in the number of authorized directors, may be filled by
a majority of the directors then in office, although less than a quorum.

                  3.6      ANNUAL MEETING. After each annual election of
directors, on the same day, the Board may meet for the purpose of organization,
the appointment of officers and the transaction of such other business at the
place where the annual meeting of the shareholders for the election of directors
is held. Notice of such meeting need not be given. Such meeting may be held at
any other time or place which shall be specified in a notice given as
hereinafter provided for special meetings of the Board or in a consent and
waiver of notice thereof signed by all the directors.

                  3.7      REGULAR MEETINGS. Regular meetings of the Board may
be held at such places either within or without the State of New Mexico and at
such times as the Board shall by resolution determine. If any day fixed for a
regular meeting shall be a legal holiday at the place where the meeting is to be
held, then the meeting which would otherwise be held on that day shall be held
at such place at the same hour and on the next succeeding business day not a
legal holiday. Notice of regular meetings need not be given.

                  3.8      SPECIAL MEETINGS. Special meetings of the Board shall
be held whenever called by the Chairman, the President, or a majority of the
directors. Notice of each such meeting shall be given to each director, at least
two days before the day on which the meeting is to be held, in accordance with
Section 5. Each such notice shall state the time and place either within or
without the State of New Mexico of the meeting but need not state the purpose
thereof, except as otherwise provided by the New Mexico Business Corporation Act
or by these Bylaws. Notice of any meeting of the Board need not be given to any
director who is present at such meeting; and any meeting of the Board shall be a
legal meeting without any notice thereof having been given if all of the
directors then in office are present at the meeting unless a director 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.

                                       -3-



                  3.9      QUORUM. Except as otherwise provided by the New
Mexico Business Corporation Act or by the Articles of Incorporation, a majority
of the total number of directors shall be required to constitute a quorum for
the transaction of business at any meeting, and the affirmative vote of a
majority of the directors present at a meeting at which a quorum is present
shall be necessary for the adoption of any resolution or the taking of any other
action.

                  3.10     TELEPHONE COMMUNICATIONS. Members of the Board or any
committee thereof may participate in a meeting of the Board or committee by
means of conference telephone or similar communications equipment by means of
which all persons participating in the meeting can hear each other.
Participation in a meeting pursuant to this subsection shall constitute presence
in person at such meeting.

                  3.11     ACTION OF DIRECTORS WITHOUT A MEETING. Any action
required or permitted to be taken at any meeting of the Board or of any
committee thereof may be taken without a meeting if all members of the Board or
of such committee, as the case may be, consent thereto in writing and such
written consent is filed with the minutes of proceedings of the Board or such
committee.

                  3.12     COMPENSATION. By resolution of the Board, each
director may be paid the director's expenses, if any, of attendance at each
meeting of the Board and may be paid a stated annual stipend as director or a
fixed sum for attendance at each meeting of the Board. No such payment shall
preclude any director from serving the Corporation in any other capacity and
receiving compensation therefor.

                  3.13     COMMITTEES. The Board may, by resolution passed by a
majority of the whole Board, designate one or more committees, each committee to
consist of one or more of the directors of the Corporation. The Board 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. Any
such committee, to the extent provided in the resolution and not prohibited by
the New Mexico Business Corporation Act, shall have and may exercise the powers
of the Board in the management of the business and affairs of the Corporation,
and may authorize the seal of the Corporation to be affixed to all papers which
may require it. Such committee or committees shall have such name or names as
may be determined from time to time by resolution adopted by the Board. Each
committee shall keep regular minutes of its meetings and report the same to the
Board when required.

         4.       OFFICERS.

                  4.1      OFFICERS. The Corporation may have such officers as
the Board may determine from time to time, including a Chairman ("Chairman"),
President, one or more Vice Presidents, a Secretary, a Treasurer, and, an
Assistant Secretary and an Assistant Treasurer. Any two or more offices may be

such manner, have such duties and hold their offices for such terms, as may be
determined by resolution of the Board.

                  4.2      APPOINTMENT OF OFFICERS. The officers shall be
appointed by the Board and each shall hold office at the pleasure of the Board
and until such officer's successor shall have been

                                       -4-

shall resign or shall have been removed in the manner hereinafter provided.

                  4.3      NO CONTRACT RIGHTS AS OFFICER. Appointment of an
officer shall not in itself create contract rights. The removal or resignation
of an officer shall not affect the officer's contract rights, if any, with the
Corporation.

                  4.4      RESIGNATION. Any officer may resign at any time by
giving written notice of resignation to the Board or to the Chairman. Any such
resignation shall take effect at the time specified therein; and, unless
otherwise specified therein, the acceptance of such resignation shall not be
necessary to make it effective.

                  4.5      REMOVAL. Any officer may be removed, either with or

general, perform all duties incident to the office of Chairman and such other

may be assigned by the Board or its Chairman or the President. In the absence of
the President, or in the event of the President's death, or inability or refusal
to act, the Vice President (or, in the event there be more than one Vice
President, the Vice Presidents in the order designated at the time of their
appointment, or in the absence of any designation, then in the order of their
appointment), if that office be created and filled, shall perform the duties of

                  4.13     POWERS AND DUTIES. In the absence of any officer of
the Corporation, or for any other reason the Board may deem sufficient, the
Board may delegate for the time being, the powers or duties of such officer, or
any of them, to any other officer or to any director. The Board may from time to
time delegate to any officer authority to appoint and remove subordinate
officers and to prescribe their authority and duties.

                  4.14     COMPENSATION. The compensation of the officers shall
be fixed from time to time by the Board. Nothing contained herein shall preclude
any officer from serving the Corporation in any other capacity, including that
of director, or from serving any of its shareholders, subsidiaries or affiliated
corporations in any capacity, and receiving proper compensation therefor.

         5.       NOTICES.

                  5.1      Notices. Whenever, under the provisions of the New
Mexico Business Corporation Act or of the Articles of Incorporation or of these
Bylaws, notice is required to be given

                                       -6-

hand-delivered or sent by United States mail with postage thereon pre-paid.
Notice to any director may be transmitted by telephonic facsimile transmission
or sent by a nationally recognized overnight courier service, in each case
addressed to the director at the director's address as it appears on the records
of the Corporation. Such notice shall be deemed to be given on the date of hand
delivery or deposit with the United States mail, or the overnight courier, or on
the date of the facsimile transmission. Notice to directors may also be given
orally, in person or by telephone, or by telegram or telex, and such notice
shall be deemed to be given upon transmission, in the case of a notice by
telegram, or upon receipt of the answer back of the telex machine of the
receiving party, in the case of a notice by telex.

                  5.2      WAIVER OF NOTICE. Whenever any notice is required to
be given under the provisions of the New Mexico Business Corporation Act or of
the Articles of Incorporation or of these Bylaws, a waiver thereof in writing,

specific instances.

                  6.2      LOANS AND EVIDENCES OF INDEBTEDNESS. No loan shall be
contracted on behalf of the Corporation, and no evidence of indebtedness shall
be issued in its name, unless authorized by the Board. Such authorization may be
general or confined to specific instances. Loans so authorized by the Board may
be effected at any time for the Corporation from any bank, trust company or
other institution, or from any firm, corporation or individual. All bonds,
debentures, notes and other obligations or evidences of indebtedness of the
Corporation issued for such loans shall be made, executed and delivered as the
Board shall authorize. When so authorized by the Board, any part of or all of
the properties, including contract rights, assets, business or good will of the
Corporation, whether then owned or thereafter acquired, may be mortgaged,
pledged, hypothecated or conveyed or assigned in trust as security for the
payment of such bonds, debentures, notes and other obligations or evidences of
indebtedness of the Corporation, and of the interest thereon, by instruments
executed and delivered in the name of the Corporation.

                  6.3      BANKING. All funds of the Corporation not otherwise
employed shall be deposited from time to time to the credit of the Corporation
in such banks, trust companies or other depositaries as the Board may authorize.

accounts, consistent with the provisions of these Bylaws, as it may deem
expedient. For the purpose of deposit and for the purpose of collection for the
account of the Corporation, checks, drafts and other orders for the payment of
money which are payable to the order of the Corporation shall be endorsed,
assigned and delivered by such person or persons and in such manner as may from
time to time be authorized by the Board.

                                       -7-



                  6.4      SECURITIES HELD BY THE CORPORATION. Unless otherwise
provided by resolution adopted by the Board, the Chairman may from time to time
appoint an attorney or attorneys, or an agent or agents, to exercise in the name
and on behalf of the Corporation the powers and rights which the Corporation may
have as the holder of stock or other securities in any other corporation to vote
or to consent in respect of such stock or other securities; and the Chairman may
instruct the person or persons so appointed as to the manner of exercising such
powers and rights and the Chairman may execute or cause to be executed in the
name and on behalf of the Corporation and under its corporate seal, or
otherwise, all such written proxies, powers of attorney or other written
instruments as he may deem necessary in order that the Corporation may exercise
such powers and rights.

         7.       STOCK CERTIFICATES.

                  7.1      STOCK CERTIFICATES. Every shareholder shall be
entitled to have a certificate certifying the number of shares of stock of the
Corporation owned by the shareholder, signed by, or in the name of the
Corporation by the Chairman and the Secretary or an Assistant Secretary of the
Corporation.

                  7.2      LOST, STOLEN OR DESTROYED CERTIFICATES. The Board may
direct a new certificate or certificates to be issued in place of any
certificate or certificates theretofore issued by the Corporation and alleged to
have been lost, stolen or destroyed, upon the making of an affidavit of that
fact by the person claiming the certificate of stock to be lost, stolen or
destroyed. When authorizing such issue of a new certificate or certificates, the
Board may, in its discretion and as a condition precedent to the issuance
thereof, require the owner of such lost, stolen or destroyed certificate or
certificates, or the shareholder's legal representative, to give the Corporation
an indemnity or a bond in such sum as it may direct as indemnity against any
claim that may be made against the Corporation with respect to the certificate
alleged to have been lost, stolen or destroyed.

                  7.3      RECORD DATE FOR DIVIDEND. In order that the
Corporation may determine the shareholders entitled to receive payment of any
dividend or other distribution or allotment of any rights or the shareholders
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 may fix a
record date which shall not precede the date upon which the resolution fixing
the record date is adopted, and which record date shall not be more than sixty
days prior to such action. If no record date is fixed, the record date for
determining the shareholders for any such purpose shall be at the close of
business on the date on which the Board adopts a resolution relating thereto.

                  7.4      PROTECTION OF CORPORATION. The Corporation shall be
entitled to recognize the exclusive right of a person registered on its books as
the owner of stock to receive dividends and shall not be bound to recognize any
equitable or other claim to or interest in such stock on the part of any other
person, whether or not it shall have express or other notice thereof, except as
otherwise provided by the laws of the State of New Mexico.

         8.       EMERGENCY REGULATIONS. The Board may adopt, either before or
during an emergency, as that term is defined by the New Mexico Business
Corporation Act, any emergency

                                       -8-



regulations permitted by the New Mexico Business Corporation Act which shall be
operative only during an emergency. In the event the Board does not adopt any
such emergency regulations, the special rules provided in the New Mexico
Business Corporation Act shall be applicable during an emergency as therein
defined.

         9.       INDEMNIFICATION.

                  9.1      RIGHT TO INDEMNIFICATION. Subject to Section 9.2,
each person who was or is made a party or is threatened to be made a party to or
is involved in any action, suit or proceeding, whether civil, criminal,
administrative or investigative (hereinafter a "proceeding"), by reason of the
fact that such person, or a person of whom such person is the legal
representative, is or was a director or officer 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 or other
enterprise, including service with respect to employee benefit plans, whether
the basis of such proceeding is alleged action in an official capacity as a
director, officer, employee or agent or in any other capacity while serving as a
director, officer, employee or agent, shall be indemnified and held harmless by
the Corporation to the fullest extent authorized by the New Mexico Business
Corporation Act, as the same exists or may hereafter be amended (but, in the
case of any such amendment, only to the extent that such amendment permits the
Corporation to provide broader indemnification rights than said law permitted
the Corporation to provide prior to such amendment), against all expense,
liability and loss (including attorneys' and experts' fees, judgments, fines,
excise taxes under the Employee Retirement Income Security Act of 1974, as in
effect from time to time, penalties and amounts to be paid in settlement)
reasonably incurred or suffered by such person in connection therewith. The
Corporation may, by action of its Board of Directors, provide indemnification to
other employees or agents of the Corporation with the same scope and effect as
the indemnification of directors and officers pursuant to this Section 9.

                  9.2      PROCEDURE FOR INDEMNIFICATION. Any indemnification
under this Section 9 (unless ordered by a court) shall be made by the
Corporation only as authorized in the specific case upon a determination that
indemnification is proper in the circumstances because the indemnitee has met
the applicable standard of conduct set forth in the New Mexico Business
Corporation Act, as the same exists or hereafter may be amended (but, in the
case of any such amendment, only to the extent that such amendment permits the
Corporation to provide broader indemnification rights than said law permitted
the Corporation to provide prior to such amendment). Such determination shall be
made (i) by the Board of Directors by a majority vote of a quorum consisting of
directors who are not parties to such action, suit or proceeding ("Disinterested
Directors"), or (ii) if such a quorum of Disinterested Directors is not
obtainable, or, even if obtainable, a quorum of Disinterested Directors so
directs, by independent legal counsel and a written opinion, or (iii) by the
shareholders. The majority of Disinterested Directors may, as they deem
appropriate, elect to have the Corporation indemnify any other employee, agent
or other person acting for or on behalf of the Corporation.

                  9.3      ADVANCES FOR EXPENSES. Costs, charges and expenses
(including attorneys' fees and experts' fees) incurred by a director or officer
of the Corporation, or such other person acting on behalf of the Corporation as
determined in accordance with Section 9.2, in defending a civil or criminal
action, suit or proceeding shall be paid by the Corporation in advance of the
final

                                       -9-



disposition of such action, suit or proceeding upon receipt of a undertaking by
or on behalf of the director, officer or other person to repay all amounts so
advanced in the event that it shall ultimately be determined that such director,
officer or other person is not entitled to be indemnified by the Corporation as
authorized in this Section 9 or otherwise.

                  9.4      OTHER RIGHTS; CONTINUATION OF RIGHT TO
INDEMNIFICATION. The indemnification and advancement of expenses provided by
this Section 9 shall not be deemed exclusive of any other rights to which a
claimant may be entitled under any law (common or statutory), bylaw, agreement,
vote of shareholders or Disinterested Directors or otherwise, both as to action
in his or her official capacity and as to any action in another capacity while
holding office or while employed by or acting as agent for the Corporation, and
shall inure to the benefit of the estate, heirs, executors and administrators of
such person. All rights to indemnification under this Section 9 shall be deemed
to be a contract between the Corporation and each director and officer of the
Corporation who serves or served in such capacity at any time while this Section
9 is in effect. Any repeal or modification of this Section 9 or any repeal or
modification of relevant provisions of the New Mexico Business Corporation Act
or any other applicable law shall not in any way diminish any rights to
indemnification of such director, officer or the obligations of the Corporation
arising hereunder with respect to any action, suit or proceeding arising out of,
or relating to, any actions, transactions or facts occurring prior to the final
adoption of such modification or repeal. For the purposes of this Section 9,
references to the "Corporation" include all constituent corporations absorbed in
a consolidation or merger as well as the resulting or surviving corporation, so
that any person who is or was a director or officer of such a constituent
corporation or is or was serving at the request of such constituent corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise shall stand in the same position under
the provisions of this Section 9, with respect to the resulting or surviving
corporation, as such person would if such person had served the resulting or
surviving corporation in the same capacity.

                  9.5      INSURANCE. The Corporation may maintain insurance, at
its expense, to protect itself and any director, officer, employee or agent of
the Corporation or another corporation, partnership, joint venture, trust or
other enterprise against any such expense, liability or loss, whether or not the
Corporation would have the power to indemnify such person against such expense,
liability or loss under the New Mexico Business Corporation Act.

         10.      MISCELLANEOUS.

                  10.1     AMENDMENTS. The Board shall have the power and
authority to alter, amend or repeal these Bylaws by the vote of a majority of
the entire Board, subject always to the power of the shareholders to change or
repeal such Bylaws.

                  10.2     FISCAL YEAR. The Board shall have the power to fix,
and from time to time change, the fiscal year of the Corporation.

                  10.3     SEAL. The Board may adopt a corporate seal which
shall be circular in form and shall have inscribed thereon the name of the
Corporation, New Mexico as the state of incorporation and the word "CORPORATE
SEAL."

                                      -10-



                  10.4     CONSTRUCTION. Unless the context specifically
requires otherwise, any reference in these Bylaws to any gender shall include
all other genders, any reference to the singular shall include the plural and
any reference to the plural shall include the singular.

                  10.5     HEADINGS. The headings in these Bylaws are included
for purposes of convenience only and shall not be considered a part of these
Bylaws in construing or interpreting any provision hereof.

                  10.6     SEVERABILITY OF PROVISIONS. If any provision of these
Bylaws or its application to any person or circumstance is held invalid or
unenforceable by a court of competent jurisdiction, the remainder of these
Bylaws, or the application of such provision to persons or circumstances other
than those to which it was held to be invalid or unenforceable, shall not be
affected thereby.

         The above Bylaws of this Corporation were adopted by the Board of
Directors of this Corporation on April 24, 2002.
