                                     OFFICES

     Section 1. PRINCIPAL OFFICES. The board of directors shall fix the location
of the principal office of the corporation at any place within or outside the
State of California. If the principal executive office is located outside this
state, and the corporation has one or more business offices in this state, the
board of directors shall fix and designate a principal business office in the
State of California.

     Section 2. OTHER OFFICES. The board of directors may at any time establish
branch or subordinate offices at any place or places where the corporation is
qualified to do business.

                                   ARTICLE II

                            MEETINGS OF SHAREHOLDERS

     Section 1. PLACE OF MEETINGS. Meetings of shareholders shall be held at any
place within or outside the State of California designated by the board of
directors. In the absence of any such designation, shareholders' meetings shall
be held at the principal executive office of the corporation.

     Section 2. ANNUAL MEETING. The annual meeting of shareholders shall be held
during the month of MARCH in each year, the exact date and time of which shall
be designated by the board of directors. At each meeting, directors shall be
elected, and any other proper business may be transacted. In no event shall the
date of the annual meeting be more than 15 months since the last annual meeting
of the shareholders.

     Section 3. SPECIAL MEETING. A special meeting of the shareholders may be
called at any time by the board of directors, or by the chairman of the board,
or by the president, or by one or more shareholders holding shares in the
aggregate entitled to cast not less than 10% of the votes at that meeting.

     If a special meeting is called by any person or persons other than the
board of directors, the request shall be in writing, specifying the time of such
meeting and the general nature of the business proposed to be transacted, and
shall be delivered personally or sent by registered mail or by telegraphic or
other facsimile transmission to the chairman of the board, the president, any
vice president, or the secretary of the corporation. The officer receiving the
request shall cause notice to be promptly given to the shareholders entitled to
vote, in accordance with the provisions of Sections 4 and 5 of this Article II,
that a meeting will be held at the time requested



by the person or persons calling the meeting, not less than thirty-five (35) nor
more than sixty (60) days after the receipt of the request. If the notice is not
given within twenty (20) days after receipt of the request, the person or
persons requesting the meeting may give the notice. Nothing contained in this
paragraph of this Section 3 shall be construed as limiting, fixing or affecting
the time when a meeting of the shareholders called by action of the board of
directors may be held.

     Section 4. NOTICE OF SHAREHOLDERS' MEETINGS. All notices of meetings of
shareholders shall be sent or otherwise given in accordance with Section 5 of
this Article II not less than ten (10) nor more than sixty (60) days before the
date of the meeting. The notice shall specify the place, date and hour of the
meeting and (i) in the case of a special meeting, the general nature of the
business to be transacted, or (ii) in the case of the annual meeting, those
matters which the board of directors, at the time of giving the notice, intends
to present for action by the shareholders. The notice of any meeting at which
directors are to be elected shall include the name of any nominee or nominees
whom, at the time of the notice, management intends to present for election.

     If action is proposed to be taken at any meeting for approval of (i) a
contract or transaction in which a director has a direct or indirect financial
interest, pursuant to Section 310 of the Corporations Code of California, (ii)
an amendment of the articles of incorporation, pursuant to Section 902 of that
Code, (iii) a reorganization of the corporation, pursuant to Section 1201 of
that code, (iv) a voluntary dissolution of the corporation, pursuant to Section
1900 of that Code, or (v) a distribution in dissolution other than in accordance
with the rights of outstanding preferred shares, pursuant to Section 2007 of
that Code, the notice shall also state the general nature of that proposal.

     Section 5. MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE. Notice of any
meeting of shareholders shall be given either personally or by first-class mail
or telegraphic or other written communication, charges prepaid, addressed to the
shareholder at the address of that shareholder appearing on the books of the
corporation or given by the shareholder to the corporation for the purpose of
notice. If no such address appears on the corporation's books or is given,
notice shall be deemed to have been given if sent to that shareholder by
first-class mail or telegraphic or other written communication to the
corporation's principal executive office, or if published at least once in a
newspaper of general circulation in the county where that office is located.
Notice shall be deemed to have been given at the time when delivered personally
or deposited in the mail or sent by telegram or other means of written
communication.

     If any notice addressed to a shareholder at the address of that shareholder
appearing on the books of the corporation is returned to the corporation by the
United States Postal Service marked to indicate that the United States Postal
Service is unable to deliver the notice to the shareholder at that address, all
future notices or reports shall be deemed to have been duly given without
further mailing if these shall be available to the shareholder on written demand
of the shareholder at the principal executive office of the corporation for a
period of one year from the date of the giving of the notice.

     An affidavit of the mailing or other means of giving any notice of any
shareholders' meeting shall be executed by the secretary, assistant secretary,
or any transfer agent of the


                                        2



corporation giving the notice, and shall be filed and maintained in the minute
book of the corporation.

     Section 6. QUORUM. The presence in person or by proxy of the holders of a
majority of the shares entitled to vote at any meeting of shareholders shall
constitute a quorum for the transaction of business. The shareholders present at
a duly called or held meeting at which a quorum is present may continue to do
business until adjournment, notwithstanding the withdrawal of enough
shareholders to leave less than a quorum, if any action taken (other than
adjournment) is approved by at least a majority of the shares required to
constitute a quorum.

     Section 7. ADJOURNED MEETING; NOTICE. Any shareholders' meeting, annual or
special, whether or not a quorum is present, may be adjourned from time to time
by the vote of the majority of the shares represented at the meeting, either in
person or by proxy, but in the absence of a quorum, no other business may be
transacted at that meeting, except as provided in Section 6 of this Article II.

     When any meeting of shareholders, either annual or special, is adjourned to
another time or place, notice need not be given of the adjourned meeting if the
time and place are announced at a meeting at which the adjournment is taken,
unless a new record date for the adjourned meeting is fixed, or unless the
adjournment is for more than forty-five (45) days from the date set for the
original meeting, in which case the board of directors shall set a new record
date. Notice of any such adjourned meeting shall be given to each shareholder of
record entitled to vote at the adjourned meeting in accordance with the
provisions of Sections 4 and 5 of this Article II. At any adjourned meeting the
corporation may transact any business which might have been transacted at the
original meeting.

     Section 8. VOTING. The shareholders entitled to vote at any meeting of
shareholders shall be determined in accordance with the provisions of Section 11
of this Article II, subject to the provisions of Sections 702 to 704, inclusive,
of the Corporations Code of California (relating to voting shares held by
fiduciary, in the name of a corporation, or in joint ownership). The
shareholders' vote may be by voice vote or by ballot; provided, however, that
any election for directors must be by ballot if demanded by any shareholder
before the voting has begun. On any matter other than elections of directors,
any shareholder may vote part of the shares in favor of the proposal and refrain
from voting the remaining shares or vote them against the proposal, but, if the
shareholder fails to specify the number of shares which the shareholder is
voting affirmatively, it will be conclusively presumed that the shareholder's
approving vote is with respect to all shares that the shareholder is entitled to
vote. If a quorum is present, the affirmative vote of the majority of the shares
represented at the meeting and entitled to vote on any matter (other than the
election of directors) shall be the act of the shareholders, unless the vote of
a greater number or voting by classes is required by California General
Corporation Law or by the articles of incorporation.

     At a shareholders' meeting at which directors are to be elected, no
shareholder shall be entitled to cumulate votes (i.e., cast for any one or more
candidates a number of votes greater than the number of shareholder's shares)
unless the candidates' names have been placed in nomination prior to
commencement of the voting and a shareholder has given notice prior to
commencement of the voting of the shareholder's intention to cumulate votes. If
any


                                        3



shareholder has given such a notice, then every shareholder entitled to vote may
cumulate votes for candidates in nomination and give one candidate a number of
votes equal to the number of directors to be elected multiplied by the number of
votes to which that shareholder's shares are entitled or distribute the
shareholder's votes on the same principle among any or all of the candidates as
the shareholder thinks fit. The candidates receiving the highest number of
votes, up to the number of directors to be elected, shall be elected.

     Section 9. WAIVER OF NOTICE OR CONSENT BY ABSENT SHAREHOLDERS. The
transactions of any meeting of shareholders either annual or special, however
called and noticed, and wherever held, shall be as valid as though had at a
meeting duly held after regular call and notice, if a quorum be present either
in person or by proxy, and if, either before or after the meeting, each person
entitled to vote, who was not present in person or by proxy, signs a written
waiver of notice or a consent to a holding of the meeting, or an approval of the
minutes. The waiver of notice or consent need not specify either the business to
be transacted or the purpose of any annual or special meeting of shareholders,
except that if action is taken or proposed to be taken for approval of any of
those matters specified in the second paragraph of Section 4 of this Article II,
the waiver of notice or consent shall state the general nature of the proposal.
All such waivers, consents or approvals shall be filed with the corporate
records or made a part of the minutes of the meeting.

     Attendance by a person at a meeting shall also constitute a waiver of
notice of that meeting, except when the person objects, at the beginning of the
meeting, to the transaction of any business because the meeting is not lawfully
called or convened, and except that attendance at a meeting is not a waiver of
any right to object to the consideration of matters not included in the notice
of the meeting if that objection is expressly made at the meeting.

     Section 10. SHAREHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING. Any
action which may be taken at any annual or special meeting of the shareholders
may be taken without a meeting and without prior notice, if a consent in
writing, setting forth the action so taken, is signed by the holders of
outstanding shares having not less than the minimum number of votes that would
be necessary to authorize or take that action at a meeting at which all shares
entitled to vote on that action were present and voted. In the case of election
of directors, such a consent shall be effective only if signed by the holders of
all outstanding shares entitled to vote for the election of directors; provided,
however, that a director may be elected at any time to fill a vacancy on the
board of directors that has not been filled by the directors, by the written
consent of the holder of a majority of the outstanding shares entitled to vote
for the election of directors. All such consents shall be filed with the
secretary of the corporation and shall be maintained in the corporate records.
Any shareholder giving a written consent, or the shareholder's proxy holders, or
a transferee of the shares or a personal representative of the shareholder or
their respective proxy holders, may revoke the consent by a writing received by
the secretary of the corporation before written consent of the number of shares
required to authorize the proposed action have been filed with the secretary.

     If the consents of all shareholders entitled to vote have not been
solicited in writing, and if the unanimous written consent of all such
shareholders shall not have been received, the secretary shall give prompt
notice of the corporate action approved by the shareholders without a meeting.
This notice shall be given in the manner specified in Section 5 of this Article
II. In the


                                        4



case of approval of (i) contracts or transactions in which a director has a
direct or indirect financial interest, pursuant to Section 310 of the
Corporations Code of California, (ii) indemnification of agents of the
corporation, pursuant to Section 317 of that Code, (iii) a reorganization of the
corporation, pursuant to Section 1201 of that Code, and (iv) a distribution in
dissolution other than in accordance with the rights of outstanding preferred
shares, pursuant to Section 2007 of that Code, the notice shall be given at
least ten (10) days before the consummation of any action authorized by that
approval.

     Section 11. RECORD DATE FOR SHAREHOLDER NOTICE, VOTING, AND GIVING
CONSENTS. For purposes of determining the shareholders entitled to notice of any
meeting or to vote or entitled to give consent to corporate action without a
meeting, the board of directors may fix, in accordance, a record date, which
shall not be more than sixty (60) days nor less then ten (10) days before the
date of any such meeting nor more than sixty (60) days before any such action
without a meeting, and in this event only shareholders of record on the date so
fixed are entitled to notice and to vote or to give consents, as the case may
be, notwithstanding any transfer of any shares on the books of the corporation
after the record date, except as otherwise provided in the California General
Corporation Law.

     If the board of directors does not so fix a record date:

     (a) The record date for determining shareholders entitled to notice of or
to vote at a meeting of shareholders shall be at the close of business on the
business day next preceding the day on which notice is given or, if notice is
waived, at the close of business on the business day next preceding the day on
which the meeting is held.

     (b) The record date for determining shareholders entitled to give consent
to corporate action in writing without a meeting, (i) when no prior action by
the board has been taken, shall be at the close of business on the day on which
the board adopts the resolution relating to that action, or the sixtieth (60th)
day before the date of such other action, whichever is later.

     Section 12. PROXIES. Every person entitled to vote for directors or on any
other matter shall have the right to do so either in person or by one or more
agents authorized by a written proxy signed by the person and filed with the
secretary of the corporation. A proxy shall be deemed signed if the
shareholder's name is placed on the proxy (whether by manual signature,
typewriting, telegraphic transmission, or otherwise) by the shareholder or the
shareholder's attorney in fact. A validly executed proxy which does not state
that it is irrevocable shall continue in full force and effect unless (i)
revoked by the person executing it, before the vote pursuant to that proxy by a
writing delivered to the corporation stating that the proxy is revoked, or by a
subsequent proxy executed by, or attendance at the meeting and voting in person
by, the person executing the proxy; or (ii) written notice of the death or
incapacity of the maker of that proxy is received by the corporation before the
vote pursuant to that proxy is counted; provided, however, that no proxy shall
be valid after the expiration of eleven (11) months from the date of the proxy,
unless otherwise provided in the proxy. The revocability of a proxy that states
on its face that it is irrevocable shall be governed by the provisions of
Sections 705(e) and 705(f) of the Corporations Code of California.


                                        5



     Section 13. INSPECTORS OF ELECTION. Before any meeting of shareholders, the
board of directors may appoint any persons other than nominees for office to act
as inspectors of election at the meeting or its adjournment. If no inspectors of
election are so appointed, the chairman of the meeting may, and on the request
of any shareholder or a shareholder's proxy shall, appoint inspectors of
election at the meeting. The number of inspectors shall be either one (1) or
three (3). If inspectors are appointed at a meeting on the request of one or
more shareholders or proxies, the holders of a majority of shares or their
proxies present at the meeting shall determine whether one (1) or three (3)
inspectors are to be appointed. If any person appointed as inspector fails to
appear or fails or refuses to act, the chairman of the meeting may, and upon the
request of any shareholder or a shareholder's proxy shall, appoint a person to
fill that vacancy.

     These inspectors shall:

     (a) Determine the number of shares outstanding and the voting power of
each, the shares represented at the meeting, the existence of a quorum, and the
authenticity, validity, and effect of proxies;

     (b) Receive votes, ballots, or consents;

     (c) Hear and determine all challenges and questions in any way arising in
connection with the right to vote;

     (d) Count and tabulate all votes or consents;

     (e) Determine when the polls shall close;

     (f) Determine the result; and

     (g) Do any other act that may be proper to conduct the election or vote
with fairness to all shareholders.

                                   ARTICLE III

                                    DIRECTORS

     Section 1. POWERS. Subject to the provisions of the California General
Corporation Law and any limitations in the articles of incorporation and these
bylaws relating to action required to be approved by the shareholders or by the
outstanding shares, the business and affairs of the corporation shall be managed
and all corporate powers shall be exercised by or under the direction of the
board of directors.

     Without prejudice to these general powers, and subject to the same
limitations, the directors shall have the power to:

     (a) Select and remove all officers, agents, and employees of the
corporation; prescribe any powers and duties for them that are consistent with
law, with the articles of


                                        6



incorporation, and with these bylaws; fix their compensation; and require from
them security for faithful service.

     (b) Change in the principal executive office or the principal business
office in the State of California from one location to another; cause the
corporation to be qualified to do business in any other state, territory,
dependency, or country and conduct business within or without the State of
California; and designate any place within or without the State of California
for the holding of any shareholders' meeting, or meetings, including annual
meetings.

     (c) Adopt, make, and use a corporate seal; prescribe the forms of
certificates of stock; and alter the form of the seal and certificates.

     (d) Authorize the issuance of shares of stock of the corporation on any
lawful terms, in consideration of money paid, labor done, services actually
rendered, debts or securities cancelled, or tangible or intangible property
actually received;

     (e) Borrow money and incur indebtedness on behalf of the corporation, and
cause to be executed and delivered for the corporation's purposes, in the
corporate name, promissory notes, bonds, debentures, deeds of trust, mortgages,
pledges, hypothecations, and other evidences of debt and securities.

     Section 2. NUMBER AND QUALIFICATION OF DIRECTORS. The authorized number of
directors shall be five (5) until changed by a duly adopted amendment to the
articles of incorporation or by an amendment to this bylaw adopted by the vote
or written consent of holders of a majority of the outstanding shares entitled
to vote; provided, however, that an amendment reducing the number of directors
to a number less than five (5) cannot be adopted if the votes cast against its
adoption at a meeting, or the shares not consenting in the case of action by
written consent, are equal to more than 16-2/3% of the outstanding shares
entitled to vote.

     Section 3. ELECTION AND TERM OF OFFICE OF DIRECTORS. Directors shall be
elected at each annual meeting of the shareholders to hold office until the next
annual meeting. Each director, including a director elected to fill a vacancy,
shall hold office until the expiration of the term for which elected and until a
successor has been elected and qualified.

     Section 4. VACANCIES. Vacancies in the board of directors may be filled by
a majority of the remaining directors, though less than a quorum, or by a sole
remaining director, except that a vacancy created by the removal of a director
by the vote or written consent of the shareholders or by court order may be
filled only by the vote of a majority of the shares entitled to vote represented
at a duly held meeting at which a quorum is present, or by the written consent
of the holders of a majority of the outstanding shares entitled to vote. Each
director so elected shall hold office until the next annual meeting of the
shareholders and until a successor has been elected and qualified.

     A vacancy or vacancies in the board of directors shall be deemed to exist
in the event of the death, resignation, or removal of any director, or if the
board of directors by resolution declares vacant the office of a director who
has been declared of unsound mind by an order of court or convicted of a felony,
or if the authorized number of directors is increased, or if the


                                        7



shareholders fail, at any meeting of shareholders at which any director or
directors are elected, to elect the number of directors to be voted for at that
meeting.

     The shareholders may elect a director or directors at any time to fill any
vacancy or vacancies not filled by the directors, but any such election by
written consent shall require the consent of a majority of the outstanding
shares entitled to vote.

     Any director may resign effective on giving written notice to the chairman
of the board, the president, the secretary, or the board of directors, unless
the notice specifies a later time for that resignation to become effective. If
the resignation of a director is effective at a future time, the board of
directors may elect a successor to take office when the resignation becomes
effective.

     No reduction of the authorized number of directors shall have the effect of
removing any director before that director's term of office expires; provided,
however, the entire Board of Directors or any individual director may be removed
from office in the manner provided by law. A director, other than the sole
shareholder-director, who becomes a disqualified person as defined in Section
13401(d) of the California Corporations Code shall cease to be a director upon
the effective date of his or her disqualification (unless he or she shall have
sooner resigned) and his or her office shall be vacant until filled as provided
in this Section.

     Section 5. PLACE OF MEETINGS AND MEETINGS BY TELEPHONE. Regular meetings of
the board of directors may be held at any place within or outside the State of
California that has been designated from time to time by resolution of the
board. In the absence of such a designation, regular meetings shall be held at
the principal executive office of the corporation. Special meetings of the board
shall be held at any place within or outside the State of California that has
been designated in the notice of the meeting or, if not stated in the notice or
there is no notice, at the principal executive office of the corporation. Any
meeting, regular or special, may be held by conference telephone or similar
communication equipment, so long as all directors participating in the meeting
can hear one another, and all such directors shall be deemed to be present in
person at the meeting.

     Section 6. ANNUAL MEETING. Immediately following each annual meeting of
shareholders, the board of directors shall hold a regular meeting for the
purpose of organization, any desired election of officers, and the transaction
of other business. Notice of this meeting shall not be required.

     Section 7. OTHER REGULAR MEETINGS. Other regular meetings of the board of
directors shall be held without call at such time as shall from time to time be
fixed by the board of directors. Such regular meetings may be held without
notice. Unless dispensed with by action of the board, a regular meeting of the
board shall be held on the 2nd Thursday of March, June, September and December
of each year, the exact date and time of which shall be set by the chairman of
the board, or if he fails to do so by the president, by the secretary, any vice
president or any two directors.


                                        8



     Section 8. SPECIAL MEETINGS. Special meetings of the board of directors for
any special purpose or purposes may be called at any time by the chairman of the
board or the president or any vice president or the secretary or any two
directors.

     Notice of the time and place of special meetings shall be delivered
personally or by telephone to each director or sent by first-class mail or
telegram, charges prepaid, addressed to each director at that director's address
as it is shown on the records of the corporation. In case the notice is mailed,
it shall be deposited in the United States mail at least four (4) days before
the time of holding of the meeting. In case the notice is delivered personally,
or by telephone or telegram, it shall be delivered personally or by telephone or
to the telegraph company at least forty-eight (48) hours before the time of the
holding of the meeting. Any oral notice given personally or by telephone may be
communicated either to the director or to a person at the office of the director
who the person giving the notice has reason to believe will promptly communicate
it to the director. The notice need not specify the purpose of the meeting nor
the place if the meeting is to be held at the principal executive office of the
corporation.

     Section 9. QUORUM. A majority of the authorized number of directors shall
constitute a quorum for the transaction of business, except to adjourn as
provided in Section 11 of this Article III. Every act or decision done or made
by a majority of the directors present at a meeting duly held at which a quorum
is present shall be regarded as the act of the board of directors, subject to
the provisions of Section 310 of the Corporations Code of California ( as to
approval of contracts or transactions in which a director has a direct or
indirect material financial interest), Section 311 of that Code (as to
appointment of committees), and Section 317(e) of that Code (as to
indemnification of directors), and subject to the following limitations:

     (a) The authorization for the issuance of shares of stock of the
corporation shall be approved by the affirmative vote of 75% or more of the
authorized number of directors of the corporation;

     (b) The act or decision to terminate the employment of any employee of the
corporation who is also a shareholder of the corporation shall be approved by
the affirmative vote of 75% or more of the authorized number of directors of the
corporation; and

     (c) The adoption of a new bylaw or amendment of a bylaw reducing the
super-majority requirements of the affirmative vote of 75% or more of the
authorized number of directors of the corporation as required by subsections (a)
or (b) of this Section 9 of this Article III shall be approved by the
affirmative vote of the authorized number of directors of the corporation.

A meeting at which a quorum is initially present may continue to transact
business notwithstanding the withdrawal of directors, if any action taken is
approved by at least a majority of the required quorum for that meeting.

     Section 10. WAIVER OF NOTICE. The transaction of any meeting of the board
of directors, however called and noticed or wherever held, shall be as valid as
though had at a meeting duly held after regular call and notice if a quorum is
present and if, either before or after the meeting, each of the directors not
present signs a written waiver of notice, a consent to


                                        9



holding the meeting or an approval of the minutes. The waiver of notice or
consent need not specify the purpose of the meeting. All such waivers, consents,
and approvals shall be filed with the corporate records or made a part of the
minutes of the meeting. Notice of a meeting shall also be deemed given to any
director who attends the meeting without protesting before or at its
commencement, the lack of notice to that director.

     Section 11. ADJOURNMENT. A majority of the directors present, whether or
not constituting a quorum, may adjourn any meeting to another time and place.

     Section 12. NOTICE OF ADJOURNMENT. Notice of the time and place of holding
an adjourned meeting need not be given, unless the meeting is adjourned for more
than twenty-four hours, in which case notice of the time and place shall be
given before the time of the adjourned meeting, in the manner specified in
Section 8 of this Article III, to the directors who were not present at the time
of the adjournment.

     Section 13. ACTION WITHOUT MEETING. Any action required or permitted to be
taken by the board of directors may be taken without a meeting, if all members
of the board shall individually or collectively consent in writing to that
action. Such action by written consent shall have the same force and effect as a
unanimous vote of the board of directors. Such written consent or consents shall
be filed with the minutes of the proceedings of the board.

     Section 14. FEES AND COMPENSATION OF DIRECTORS. Directors and members of
committees may receive such compensation, if any, for their services, and such
reimbursement of expenses, as may be fixed or determined by resolution of the
board of directors. This Section 14 shall not be construed to preclude any
director from serving the corporation in any other capacity as an officer,
agent, employee, or otherwise, and receiving compensation for those services.

                                   ARTICLE IV

                                   COMMITTEES

     Section 1. COMMITTEES OF DIRECTORS. The board of directors may, by
resolution adopted by a majority of the authorized number of directors,
designate one or more committees, each consisting of two or more directors, to
serve at the pleasure of the board. The board may designate one or more

California, also requires shareholders' approval or approval of the outstanding

notice), 11 (adjournment), 12 (notice of adjournment), and 13 (action without

members, except that the time of regular meetings of committees may be
determined either by resolution of the board of directors or by resolution of
the committee; special meetings of committees may also be called by resolution
of the board of directors; and notice of special meetings of committees shall
also be given to all alternate members, who shall have the right to attend all

                                   ARTICLE VI

                               INDEMNIFICATION OF
                    OFFICERS, DIRECTORS, EMPLOYEES AND AGENTS

     Section 1. RIGHT TO INDEMNIFICATION. Each person who was or is a party or
is threatened to be made a party to or is involved (as a party, witness, or
otherwise), in any threatened, pending, or completed action, suit, or
proceeding, whether civil, criminal, administrative, or investigative (hereafter
a "Proceeding"), by reason of the fact that he, or a person of whom he 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 foreign or domestic
corporation, partnership, joint venture, trust, or other enterprise, or was a
director, officer, employee or agent of a foreign or domestic corporation that
was a predecessor corporation of the corporation or of another enterprise at the
request of such predecessor corporation, including service with respect to
employee benefit plans, whether the basis of the Proceeding is alleged action in
an official capacity as a director, officer, employee, or agent or in any other
capacity while service as a director, officer, employee, or agent (hereafter an
"Agent"), shall be indemnified and held harmless by the corporation to the
fullest extent authorized by statutory and decisional law, as the same exists or
may hereafter be interpreted or amended (but, in the case of any such amendment
or interpretation, only to the extent that such amendment or interpretation
permits the corporation to provide broader indemnification rights than were
permitted prior thereto) against all expenses, liability, and loss (including
attorney's fees, judgments, fines, ERISA excise taxes and penalties, amounts
paid or


                                       13



to be paid in settlement, any interest, assessments, or other charges imposed
thereon, and any federal, state, local, or foreign taxes imposed on any Agent as
a result of the actual or deemed receipt of any payments under this Article)
reasonably incurred or suffered by such person in connection with investigating,
defending, being a witness in, or participating in (including the appeal), or
preparing for any of the foregoing in, any Proceeding (hereafter "Expenses");
provided, however, that except as to actions to enforce indemnification rights
pursuant to Section 3. of this ARTICLE VI, the corporation shall indemnify any
Agent seeking indemnification in connection with a Proceeding (or part thereof)
initiated by such person only if the Proceeding (or part thereof) was authorized
by the Board of Directors of the corporation.

The right to indemnification conferred in this Article shall be a contract
right. It is the corporation's intention that these bylaws provide
indemnification in excess of that expressly permitted by Section 317 of the
California General Corporation Law, as authorized by the corporation's Articles
of Incorporation.

     Section 2. AUTHORITY TO ADVANCE EXPENSES. Expenses incurred by an officer
or director (acting in his capacity as such) in defending a Proceeding shall be
paid by the corporation in advance of the final disposition of such Proceeding,
provided, however, that if required by the California General Corporation Law,
as amended, such Expenses shall be advanced only upon delivery to the
corporation of an undertaking by or on behalf of such director or officer to
repay such amount if it shall ultimately be determined that he is not entitled
to be indemnified by the corporation as authorized in this Article or otherwise.
Expenses incurred by other Agents of the corporation (or by the directors or
officers not acting in their capacity as such, including service with respect to
employee benefit plans) may be advanced upon the receipt of a similar
undertaking, if required by law, and upon such other terms and conditions as the
Board of Directors deems appropriate. Any obligations to reimburse the
corporation for Expense advances shall be unsecured and no interest shall be
charged thereon.

     Section 3. RIGHT OF CLAIMANT TO BRING SUIT. If a claim under Section 1. or
2. of this ARTICLE VI is not paid in full by the corporation within thirty (30)
days after a written claim has been received by the corporation, the claimant
may at any time thereafter bring suit against the corporation to recover the
unpaid amount of the claim and, if successful in whole or in part, the claimant
shall be entitled to be paid also the expense (including attorney's fees) of
prosecuting such claim. It shall be a defense to any such action (other than an
action brought to enforce a claim for expenses incurred in defending a
Proceeding in advance of its final disposition where the required undertaking
has been tendered to the corporation) that the claimant has not met the
standards of conduct that make it permissible under the California General
Corporation Law for the corporation to indemnify the claimant for the amount
claimed. The burden of proving such a defense shall be on the corporation.
Neither the failure of the corporation (including its Board of Directors,
independent legal counsel, or its stockholders) to have made a determination
prior to the commencement of such action that indemnification of the claimant is
proper under the circumstances because he has met the applicable standard of
conduct set forth in the California General Corporation Law, nor an actual
determination by the corporation (including its Board of Directors, independent
legal counsel, or its stockholders) that the claimant had not met such
applicable standard of conduct, shall be a defense to the action or create a
presumption that claimant has not met the applicable standard of conduct.


                                       14



     Section 4. PROVISIONS NONEXCLUSIVE. The rights conferred on any person by
this Article shall not be exclusive of any other rights that such person may
have or hereafter acquire under any statute, provision of the Articles of
Incorporation, agreement, vote of stockholders or disinterested directors, or
otherwise, both as to action in an official capacity and as to action on another
capacity while holding such office. To the extent that any provision of the
Articles, agreement, or vote of the stockholders or disinterested directors is
inconsistent with these bylaws, the provision, agreement, or vote shall take
precedence.

     Section 5. AUTHORITY TO INSURE. The corporation may purchase and maintain
insurance to protect itself and any Agent against any Expense asserted against
or incurred by such person, whether or not the corporation would have the power
to indemnify the Agent against such Expense under applicable law or the
provisions of this Article, provided that, in cases where the corporation owns
all or a portion of the shares of the company issuing the insurance policy, the
company and/or the policy must meet one of the two sets of conditions set forth
in Section 317 of the California General Corporation Law, as amended.

     Section 6. SURVIVAL OF RIGHTS. The rights provided by this Article shall
continue as to a person who has ceased to be an Agent and shall inure to the
benefit of the heirs, executors, and administrators of such person.

     Section 7. SETTLEMENT OF CLAIMS. The corporation shall not be liable to
indemnify any Agent under this Article (a) for any amounts paid in settlement of
any action or claim effected without the corporation's written consent, which
consent shall not be unreasonably withheld; or (b) for any judicial award, if
the corporation was not given a reasonable and timely opportunity, at its
expense, to participate in the defense of such action.

     Section 8. EFFECT OF AMENDMENT. Any amendment, repeal, or modification of
this Article shall not adversely affect any right or protection of any Agent
existing at the time of such amendment, repeal, or modification.

     Section 9. SUBROGATION. In the event of payment under this Article, the
corporation shall be subrogated to the extent of such payment to all of the
rights of recovery of the Agent, who shall execute all papers required and shall
do everything that may be necessary to secure such rights, including the
execution of such documents necessary to enable the corporation effectively to
bring suit to enforce such rights.

     Section 10. DUPLICATION OF PAYMENTS. The corporation shall not be liable
under this Article to make any payment in connection with any claim made against
the Agent to the extent the Agent has otherwise actually received payment (under
any insurance policy, agreement, vote, or otherwise) of the amounts otherwise
indemnifiable hereunder.

                                   ARTICLE VII

                               RECORDS AND REPORTS

     Section 1. MAINTENANCE AND INSPECTION OF SHARE REGISTER. The corporation
shall keep at its principal executive office, or at the office of its transfer
agent or registrar, if either be appointed and as determined by resolution of
the board of directors, a


                                       15



record of its shareholders, giving the names and addresses of all shareholders
and the number and class of shares held by each shareholder.

     A shareholder or shareholders of the corporation holding at least five
percent (5%) in the aggregate of the outstanding voting shares of the
corporation may (i) inspect and copy the records of shareholders' names and
addresses and shareholdings during usual business hours on five days prior
written demand on the corporation, and (ii) obtain from the transfer agent of
the corporation, on written demand and on the tender of such transfer agent's
usual charges for such list, a list of the shareholders' names and addresses,
who are entitled to vote for the election of directors, and their shareholdings,
as of the most recent record date for which that list has been compiled or as of
a date specified by the shareholder after the date of demand. This list shall be
made available to any such shareholder by the transfer agent on or before the
later of five (5) days after the demand is received or the date specified in the
demand as the date as of which the list is to be compiled. The record of
shareholders shall also be open to inspection on the written demand of any
shareholders shall also be open to inspection on the written demand of any
shareholder or holder of a voting trust certificate, at any time during usual
business hours, for a purpose reasonably related to the holder's interests as a
shareholder or as the holder of a voting trust certificate. Any inspection and
copying under this Section 1 may be made in person or by an agent or attorney of
the shareholder or holder of a voting trust certificate making the demand.

     Section 2. MAINTENANCE AND INSPECTION OF BYLAWS. The corporation shall keep
at its principal executive office, or if its principal business office is not in
this state, the original or a copy of the bylaws as amended to date, which shall
be open to inspection by the shareholders at all reasonable times during office
hours. If the principal executive office of the corporation is outside the State
of California and the corporation has no principal business office in this
state, the secretary shall, upon the written request of any shareholder, furnish
to that shareholder a copy of the bylaws as amended to date.

     Section 3. MAINTENANCE AND INSPECTION OF OTHER CORPORATE RECORDS. The
accounting books and records and minutes of proceedings of the shareholders and
the board of directors and any committee or committees of the board of directors
shall be kept at such place or places designated by the board of directors, or,
in the absence of such designation, at the principal executive office of the
corporation. The minutes shall be kept in written form and the accounting books
and records shall be kept either in written form or in any other form capable of
being converted into written form. The minutes and accounting books and records
shall be open to inspection upon the written demand of any shareholder or holder
of a voting trust certificate, at any reasonable time during usual business
hours, for a purpose reasonably related to the holder's interests as a
shareholder or as the holder of a voting trust certificate. The inspection may
be made in person or by an agent or attorney, and shall include the right to
copy and make extracts. These rights of inspection shall extend to the records
of each subsidiary corporation of the corporation.

     Section 4. INSPECTION BY DIRECTORS. Every director shall have the absolute
right at any reasonable time to inspect all books, records, and documents of
every kind and the physical properties of the corporation and each of its
subsidiary corporations. This inspection by a director may be made in person or
by an agent or attorney and the right of inspection includes the right to copy
and make extracts of documents.


                                       16



     Section 5. ANNUAL REPORT TO SHAREHOLDERS. The annual report to shareholders
referred to in Section 1501 of the California General Corporation Law is
expressly dispensed with, but nothing herein shall be interpreted as prohibiting
the board of directors from issuing annual or other periodic reports to the
shareholders of the corporation as they consider appropriate.

     Section 6. FINANCIAL STATEMENTS. A copy of any annual financial statement
and any income statement of the corporation for each quarterly period of each
fiscal year, and any accompanying balance sheet of the corporation as of the end
of each such period, that has been prepared by the corporation shall be kept on
file in the principal executive office of the corporation for twelve (12) months
and each such statement shall be exhibited at all reasonable times to any
shareholder demanding an examination of any such statement or a copy shall be
mailed to any such shareholder.

     If a shareholder or shareholders holding at least five percent (5%) of the
outstanding shares of any class of stock of the corporation makes a written
request to the corporation for an income statement of the corporation for the
three-month, six-month or nine-month period of the then current fiscal year
ended more than thirty (30) days before the date of the request, and a balance
sheet of the corporation as of the end of that period, the chief financial
officer shall cause that statement to be prepared, if not already prepared, and
shall deliver personally or mail that statement or statements to the person
making the request within thirty (30) days after the receipt of the request. If
the corporation has not sent to the shareholders its annual report for the last
fiscal year, this report shall likewise be delivered or mailed to the
shareholder or shareholders within thirty (30) days after the request.

     The corporation shall also, on the written request of any shareholder, mail
to the shareholder a copy of the last annual, semi-annual, or quarterly income
statement which it has prepared, and a balance sheet as of the end of that
period.

     The quarterly income statements and balance sheets referred to in this

                                       17



     Section 1. ONLY LICENSED PERSONS SHALL OWN. No shares may be issued to any
person other than a licensed person as defined in Section 13401(c) of the
California Corporations Code or a medical corporation which renders professional
services if such medical corporation has only one shareholder who is a licensed
person as defined in Section 13401 of the California Corporations Code.

     Section 2. TRANSFER OF SHARES. A transfer or purported transfer of shares
of this corporation to any unlicensed person or in violation of the regulations
issued by the Board of Medical Quality Assurance shall be void.

     Section 3. SHARES OF DECEASED OR DISQUALIFIED SHAREHOLDER. When this
corporation has two or more shareholders and one of its shareholders dies or
becomes a disqualified person as defined in Section 13401(d) of the California
Corporations Code, his or her shares shall be sold and transferred to this
corporation, to one or more of the other shareholders of this corporation or to
other eligible licensed persons on such terms as are agreed upon. Such sale or
transfer shall not be later than six (6) months after any such death and not
later than ninety (90) days after the date the shareholder becomes a
disqualified person. If no such agreement shall be in effect, or, if in effect,
if such agreement shall be in dispute, in default, or unperformed, then upon the
last day for mandatory sale required by this Section 3, the corporation may
cancel all of such shares without the necessity of the physical surrender of the
certificates evidencing such shares and such deceased or disqualified
shareholder shall upon cancellation cease to be a shareholder of this
corporation. Nothing in this Section 3 shall in any way impair any of the rights
of any such disqualified shareholder or representative of any such deceased
shareholder to claim just compensation for the value of his or her shares.

     Section 4. REPURCHASE OF SHARES. This corporation may repurchase its own
shares without regard to any restrictions provided by law upon the repurchase of

corporation attributable to professional services rendered while any shareholder
is a disqualified person as defined in the Professional Corporations Act shall
in any manner be distributed or accrue to the benefit of such shareholder or his
or her shares in this corporation.

     Section 6. REPURCHASE BY A DISQUALIFIED PERSON -- SHARE CERTIFICATE LEGEND.
In the event any shareholder becomes a disqualified person and his or her shares
are transferred and sold to the corporation and/or its other shareholders, and
if the corporation and its shareholders agree that such shares may be resold to
such person if and when he or she becomes an eligible shareholder, then the
share certificates of the corporation shall contain an appropriate legend
setting forth such restrictions.

                                   ARTICLE IX

                            GENERAL CORPORATE MATTERS

     Section 1. RECORD DATE FOR PURPOSES OTHER THAN NOTICE AND VOTING. For
purposes of determining the shareholders entitled to receive payment of any


                                       18



dividend or other distribution or allotment of any rights or entitled to
exercise any rights in respect of any other lawful action (other than action by
shareholders by written consent without a meeting), the board of directors may
fix, in advance, a record date, which shall not be more than sixty (60) days
before any such action, and in that case only shareholders of record on the date
so fixed are entitled to receive the dividend, distribution, or allotment of
rights or to exercise the rights, as the case may be, notwithstanding any
transfer of any shares on the books of the corporation after the record date so
fixed, except as otherwise provided in the California General Corporation Law.

     If the board of directors does not so fix a record date, the record date
for determining shareholders for any such purpose shall be at the close of
business on the day on which the board adopts the applicable resolution or the
sixtieth (60th) day before the date of that action, whichever is later.

     Section 2. CHECKS, DRAFTS, EVIDENCES OF INDEBTEDNESS. All checks, drafts,
or other orders for payment of money, notes, or other evidences of indebtedness,
issued in the name of or payable to the corporation, shall be signed or endorsed
by such person or persons and in such manner as, from time to time, shall be
determined by resolution of the board of directors.

     Section 3. CORPORATE CONTRACTS AND INSTRUMENTS; HOW EXECUTED. The board of
directors, except as otherwise provided in these bylaws, may authorize any
officer or officers, agent or agents, to enter into any contract or execute any
instrument in the name of and on behalf of the corporation, and this authority
may be general or confined to specific instances; and, unless so authorized or
ratified by the board of directors or within the agency power of an officer, no
officer, agent, or employee shall have any power or authority to bind the
corporation by any contract or engagement or to pledge its credit or to render
it liable for any purpose or for any amount.

     Section 4. CERTIFICATES FOR SHARES. A certificate or certificates for
shares of the capital stock of the corporation shall be issued to each
shareholder when any of these shares are fully paid, and the board of directors
may authorize the issuance of certificates or shares as partly paid provided
that these certificates shall state the amount of the consideration to be paid
for them and the amount paid. All certificates shall be signed in the name of
the corporation by the chairman of the board or vice chairman of the board or
the president or vice president and by the chief financial officers or an
assistant treasurer or the secretary or any assistant secretary, certifying the
number of shares and the class or series of shares owned by the shareholder. Any
or all of the signatures on the certificate may be facsimile. In case any
officer, transfer agent, or registrar who has signed or whose facsimile
signature has been placed on a certificate shall have ceased to be that officer,
transfer agent, or registrar before that certificate is issued, it may be issued
by the corporation with the same effect as if that person were an officer,
transfer agent, or registrar at the date of issue.

     Section 5. LOST CERTIFICATES. Except as provided in this Section 5, no new
certificates for shares shall be issued to replace an old certificate unless the
latter is surrendered to the corporation and cancelled at the same time. The
board of directors may, in case any share certificate or certificate for any
other security is lost, stolen, or destroyed, authorize the issuance


                                       19



of a replacement certificate on such terms and conditions as the board may
require, including provision for indemnification of the corporation secured by a
bond or other adequate security sufficient to protect the corporation against
any claim that may be made against it, including any expense or liability, on
account of the alleged loss, theft, or destruction of the certificate or the
issuance of the replacement certificate.

     Section 6. REPRESENTATION OF SHARES OF OTHER CORPORATIONS. The chairman of
