time. [BCA Section 3.10(j)]

     Section 1.2 Registered Office in Illinois. The Registered Office of the
Corporation required by the Illinois Business Corporation Act of 1983 ("BCA") to
be maintained in the State of Illinois may be, but need not be, the same as the

Illinois, but shall in any event be identical with the business office of the
Corporation's Registered Agent in Illinois. [BCA Section 5.05] The address of
the Registered Office in Illinois may be changed from time to time by the Board
of Directors or by such Registered Agent. [BCA Sections 5.10, 5.20]

                                    Article 2
                                  SHAREHOLDERS

     Section 2.1 Annual Meeting. Except as the Board of Directors of the
Corporation may otherwise provide by resolution duly adopted pursuant to the
authority granted hereby, the Annual Meeting of Shareholders of the Corporation
shall be held each year on the First Monday of December 31 (beginning with the
year 1992), commencing at the hour of 10:00 A.M., for the purpose of electing
Directors and for the transaction of such other business as may properly come
before the Meeting. If the day fixed for the Annual Meeting shall be a legal
holiday, such Meeting shall be held on the next succeeding business day. [BCA
Section 7.05]

     Section 2.2 Special Meetings. Special Meetings of the Shareholders may be
called by the President, by the Board of Directors, or by the holders of not
less than one-fifth of all the outstanding shares of the Corporation entitled to
vote on the matter for which the Special Meeting is called. [BCA Section 7.05]

     Section 2.3 Place of Meeting. The Board of Directors may by resolution
designate any place, either within or without the State of Illinois, as the
place of meeting for any Annual Meeting of Shareholders or for any Special
Meeting called by the Board of Directors or by the President, and may designate

Shareholders. A waiver of notice signed by all Shareholders may designate any
place, either within or without the State of Illinois, as the place for the
holding of any Meeting. If no designation of a meeting place is made, or if a
Special Meeting be otherwise called, the place of meeting shall be the
Registered Office of the Corporation in the State of Illinois, except as
otherwise provided in Section 2.5 of these By-Laws. [BCA Section 7.05]

     Section 2.4 Notice of Meeting. Written notice stating the place, day 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 delivered not less than ten
(10) nor more than sixty (60) days before the date of



                    LIFECARE AMBULANCE SERVICE, INC. BY-LAWS

the Meeting, or, in the case of a merger, consolidation, share exchange,
dissolution, or sale, lease or exchange of assets requiring Shareholder
approval, not less than twenty (20) nor more than sixty (60) days before the
date of the Meeting, either personally or by mail, by or at the direction of the
President, or the Secretary, or the Officer or persons calling the meeting, to
each Shareholder of record entitled to vote at such Meeting. If mailed, such
notice shall be deemed to be delivered when deposited in the United States mail,
addressed to the Shareholder at his or her address as it appears on the records
of the Corporation, with postage thereon prepaid. [BCA Section 7.15]

     Section 2.5 Meeting Of All Shareholders. If all of the Shareholders shall

consent to the holding of a Meeting at such time and place, such Meeting shall
be valid without call or notice, and at such Meeting any corporate action may be
taken. [BCA Section 7.20]

     Section 2.6 Fixing of Record Date. For the purpose of determining
Shareholders entitled to notice of or to vote at any Meeting of Shareholders, or
Shareholders entitled to receive payment of any dividend or distribution, or in
order to make a determination of Shareholders for any other proper purpose, the
Board of Directors of the Corporation may fix in advance a date as the record
date for any such determination of Shareholders, such date in any case to be not
more than sixty (60) days immediately preceding the date of the Meeting, payment
or other transaction, and, for a Meeting of Shareholders, not less than ten (10)
days, or in the case of a merger, consolidation, share exchange, dissolution, or
sale, lease or exchange of assets requiring Shareholder approval, not less than
twenty (20) days, immediately preceding such Meeting. If no record date is fixed
for the determination of Shareholders entitled to notice of or to vote at a
Meeting of Shareholders, or Shareholders entitled to receive payment of a
dividend or other distribution, the date on which notice of the Meeting is
mailed or the date on which the resolution of the Board of Directors declaring
such dividend or distribution is adopted, as the case may be, shall be the
record date for such determination of Shareholders. When a determination of
Shareholders entitled to vote at any Meeting of Shareholders has been made as
provided in this Section 2.6, such determination shall apply to any adjournment
thereof. [BCA Section 7.25]

     Section 2.7 Voting Lists. The Officer or agent having charge of the
transfer books and records for shares of the Corporation shall make, within
twenty (20) days after the record date for a Meeting of Shareholders or ten (10)
days before such Meeting, whichever is earlier, a complete list of the
Shareholders entitled to vote at such Meeting, arranged in alphabetical order,
with the address of and the number of shares held by each, which list, for a
period of ten (10) days prior to such Meeting, shall be kept on file at the
Registered Office of the Corporation and shall be subject to inspection by any
Shareholder, and to copying at the Shareholder's expense, at any time during
usual business hours. Such list shall also be produced and kept open at the time
and place of the Meeting and shall be subject to the inspection of any
Shareholder during the whole time of the Meeting. The original share ledger or
transfer book, or a duplicate thereof kept in Illinois, shall be prima facie
evidence as to who are the Shareholders entitled to examine such list or share
ledger or transfer book, or to vote at any Meeting of Shareholders. Failure to
comply with the requirements of this Section 2.7 shall not affect the validity
of any action taken at such Meeting. An Officer or agent having charge of the
transfer books or records who shall fail to prepare the list of Shareholders, or
keep the same on file for a period of ten (10) days, or


                                       2



                    LIFECARE AMBULANCE SERVICE, INC. BY-LAWS

produce and keep the same open for inspection at the Meeting, as provided in
this Section 2.7, shall be liable to any Shareholder suffering damage on account
of such failure, to the extent of such damage as provided by law. [BCA Section
7.30]

     Section 2.8 Quorum of Shareholders. A majority of the outstanding shares of
the Corporation entitled to vote on a matter, represented in person or by proxy,
shall constitute a quorum for consideration of such matter at a meeting of
Shareholders. If a quorum is present, the affirmative vote of the majority of
the shares represented at the Meeting and entitled to vote on a matter shall be
the act of the Shareholders, unless the vote of a greater number or voting by
classes is required by the Illinois Business Corporation Act of 1983, by the
Corporation's Articles of Incorporation, or by these By-Laws. [BCA Section 7.60]

     Section 2.9 Proxies. A Shareholder may appoint a proxy to vote or otherwise
act for him or her by signing an appointment form and delivering it to the
person so appointed. No proxy shall be valid after the expiration of eleven (11)
months from the date thereof unless otherwise provided in the proxy. Every proxy
continues in full force and effect until revoked by the person executing it
prior to the vote pursuant thereto, except as otherwise provided in this Section
2.9 and in Section 7.50 of the Illinois Business Corporation Act of 1983. Such
revocation may be effected by a writing delivered to the Corporation stating
that the proxy is revoked or by a subsequent proxy executed by, or by attendance
at the Meeting and voting in person by, the person executing the proxy. The
dates contained on the forms of proxy presumptively determine the order of
execution, regardless of any postmark dates on envelopes in which they are
mailed. An appointment of a proxy is revocable by the Shareholder unless the
appointment form conspicuously states that it is irrevocable and the appointment
is coupled with an interest in the shares or in the Corporation generally.
Unless the appointment of a proxy contains an express limitation on the proxy's
authority, the Corporation may accept the proxy's vote or other action as that
of the Shareholder making the appointment. [BCA Section 7.50]

     Section 2.10 Voting of Shares. Each outstanding share of the Corporation
shall be entitled to one vote in each matter submitted to a vote by the
Shareholders, except as the Illinois Business Corporation Act of 1983 and the
Corporation's Articles of Incorporation may otherwise limit or deny voting
rights or provide special voting rights as to any class or classes or series of
shares. [BCA Section 7.40]

     Section 2.11 Voting of Shares by Certain Holders. Shares of its own stock
belonging to this Corporation shall not be voted, directly or indirectly, at any
Meeting and shall not be counted in determining the total of outstanding shares
at any given time, but shares of the Corporation held by the Corporation in a
fiduciary capacity may be voted and shall be counted in determining the total
number of outstanding shares entitled to vote at any given time.

     Shares registered in the name of another corporation, domestic or foreign,
may be voted by any Officer, agent, proxy or other legal representative
authorized to vote such shares under the law of incorporation of such
corporation. The Corporation may treat the president or other person holding the
position of chief executive officer of such other corporation as authorized to
vote such shares, together with any other person indicated and any other holder
of an office indicated by the corporate Shareholder to the Corporation as a
person or office authorized to vote such shares. Such persons and offices
indicated shall be registered by the Corporation on the


                                       3



                    LIFECARE AMBULANCE SERVICE, INC. BY-LAWS

transfer books for shares and included in any voting list prepared in accordance
with Section 2.7 of these By-Laws.

     Shares registered in the name of a deceased person, a minor ward or a
person under legal disability may be voted by his or her administrator, executor
or court appointed guardian, either in person or by proxy without a transfer of
such shares into the name of such administrator, executor or court appointed
guardian. Shares registered in the name of a trustee may be voted by him or her,
either in person or by proxy.

     Shares registered in the name of a receiver may be voted by such receiver,
and shares held by or under the control of a receiver may be voted by such
receiver without the transfer thereof into his or her name if authority so to do
is contained in an appropriate order of the court by which such receiver was
appointed.

     A Shareholder whose shares are pledged shall be entitled to vote such
shares until the shares have been transferred into the name of the pledgee, and
thereafter the pledgee shall be entitled to vote the shares so transferred. [BCA
Section 7.45]

     Section 2.12 Voting by Ballot; Inspectors. Voting by Shareholders on any
matter or in any election may be viva voce unless the Chairman of the Meeting
shall order, or any Shareholder entitled to vote thereon shall demand, that
voting be by ballot.

     At any Meeting of Shareholders, the Chairman of the Meeting may, or upon
the request of any Shareholder shall, appoint one or more persons as inspectors
for such Meeting. Such inspectors shall ascertain and report the number of
shares represented at the Meeting, based upon their determination of the
validity and effect of proxies; count all votes and report the results; and do
such other acts as are proper to conduct the election and voting with
impartiality and fairness to all the Shareholders. Each report of an inspector
shall be in writing and signed by him or her or by a majority of them if there
be more than one inspector acting at such Meeting. If there is more than one
inspector, the report of a majority shall be the report of the inspectors. The
report of the inspector or inspectors on the number of shares represented at the
Meeting and the results of the voting shall be prima facie evidence thereof.
[BCA Section 7.35]

     Section 2.13 Informal Action by Shareholders. Any action required to be
taken at any Annual or Special Meeting of Shareholders of the Corporation, or
any other action which may be taken at a Meeting of the Shareholders, may be
taken without a Meeting and without a vote, if a consent in writing, setting
forth the action so taken, shall be signed (i) by the holders of outstanding
shares 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 voting or (ii) by all of the Shareholders entitled
to vote with respect to the subject matter thereof. If such consent is signed by
less than all of the Shareholders entitled to vote, then such consent shall
become effective only if, at least five (5) days prior to the execution of the
consent, a notice of the proposed action is delivered in writing to all of the
Shareholders entitled to vote with respect to the subject matter thereof and,
after the effective date of the consent, prompt notice of the taking of the
action without a meeting by less than unanimous written consent shall be
delivered in writing to those Shareholders who have not consented in writing.

the successor shall not take office until the effective date. [BCA Sections
8.01, 8.10]

     Section 3.3 Regular Meetings. A Regular Meeting of the Board of Directors

notice than such resolution. [BCA Sections 8.20, 8.25]

     Section 3.4 Special Meetings. Special Meetings of the Board of Directors
may be called by or at the request of the President or any two Directors. The
person or persons authorized to call Special Meetings of the Board of Directors

for holding any Special Meeting of the Board of Directors called by them. [BCA
Sections 8.20, 8.25]

     Section 3.5 Notice. Notice of any Special Meeting shall be given at least
three days previous thereto by written notice delivered personally or by
telegram or mailgram to each Director at his or her business address, or given
at least five (5) days previous thereto if mailed. If mailed, such notice shall
be deemed to be delivered on the second day following the date on which it was
deposited in the United States mail so addressed, with proper postage thereon
prepaid. If notice be given by telegram or mailgram, such notice shall be deemed
to be delivered when the telegram or mailgram is delivered to the telegraph

waiver of notice. The attendance of a Director at any Meeting shall constitute a
waiver of notice of such Meeting, except where a Director attends a Meeting for
the express purpose of objecting 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 Board
of Directors need be specified in the notice or waiver of notice of such
Meeting. [BCA Section 8.25]

     Section 3.7 Manner Of Action. The act of the majority of Directors present
at a Meeting at which a quorum is present shall be the act of the Board of
Directors. [BCA Section 8.15 (c)]

     Section 3.8 Vacancies. Any vacancy occurring in the Board of Directors and
any directorship to be filled by reason of an increase in the number of
Directors may be filled by election at an Annual Meeting or at a Special Meeting
of Shareholders called for that purpose. In the absence of a Special Meeting of
Shareholders, the Board of Directors may fill the vacancy, except as otherwise
specified in the Articles of Incorporation. A Director elected by the
Shareholders to fill a vacancy shall hold office for the balance of the term for
which he or she was elected. A Director appointed to fill a vacancy shall serve
until the next Meeting of Shareholders at which Directors are to be elected.
[BCA Section 8.30]

     Section 3.9 Removal Of Directors. One or more of the Directors may be
removed, with or without cause, at a Meeting of Shareholders by the affirmative
vote of the holders of a majority of the outstanding shares then entitled to
vote at an election of Directors, except that:

     (a) No Director shall be removed at a Meeting of Shareholders unless the
notice of such Meeting shall state that a purpose of the Meeting is to vote upon
the removal of one or more Directors named in the notice. Only the named
Director or Directors may be removed at such Meeting.

     Section 3.10 Compensation. Except as otherwise provided in any written
agreement and except as otherwise set forth below, the Board of Directors, by
the affirmative vote of a majority of Directors then in office, and irrespective
of any personal interest of any of its members, shall have authority to
establish reasonable compensation of all Directors for services to the
Corporation as Directors, Officers or otherwise. [BCA Section 8.05 (b)] By
resolution of the Board of Directors, the Directors may be paid their expenses,
if any, of attendance at each Meeting of the Board of Directors. In the event
the Internal Revenue Service shall determine any such compensation paid to a
Director to be unreasonable or excessive, such Director must repay to the
Corporation the excess over what is determined to be reasonable compensation,
with interest on such excess at the rate of nine percent (9%) per annum, within
ninety (90) days after notice from the Corporation.

     Section 3.11 Presumption Of Assent. A Director of the Corporation who is
present at a Meeting of the Board of Directors at which action on any corporate
matter is taken shall be conclusively presumed to have assented to the action
taken unless his or her dissent shall be entered in the minutes of the Meeting
or unless he or she shall file his or her written dissent to such action with
the person acting as the Secretary of the Meeting before the adjournment thereof
or shall forward such dissent by registered or certified mail to the Secretary
of the Corporation immediately after the adjournment of the Meeting. Such right

the Board of Directors, or any other action which may be taken at a Meeting of
the Board of Directors or of a Committee thereof, may be taken without a Meeting
if a consent in writing, setting forth the action so taken, is signed by all the
Directors entitled to vote with respect to the subject matter thereof, or by all
the members of such Committee, as the case may be. The consent shall be
evidenced by one or more written approvals, each of which sets forth the action
taken and bears the signature of one or more Directors. All the approvals
evidencing the consent shall be delivered to the Secretary to be filed in the
corporate records. The action taken shall be effective when all the Directors
have approved the consent unless the consent specifies a different effective
date. Any such consent signed by all the Directors or all the members of a
Committee shall have the same effect as a unanimous vote. [BCA Section 8.45]

     Section 3.13 Participation By Conference Telephone. Members of the Board of
Directors or of any Committee of the Board of Directors may participate in and
act at any Meeting of the Board of Directors or any Committee through the use of
a conference telephone or other communications equipment by means of which all
persons participating in the Meeting can hear each other. Participation in such
Meeting shall constitute attendance and presence in person at the Meeting of the
person or persons so participating. [BCA Section 8.15 (d)]

     Section 3.14 Committees. A majority of the Directors may create one or more
Committees and appoint members of the Board of Directors to serve on such
Committee or Committees. Each Committee shall have two or more members, who
serve at the pleasure of the Board of Directors.

     Unless the appointment by the Board of Directors requires a greater number,
a majority of any Committee shall constitute a quorum and a majority of a quorum
is necessary for Committee action. A Committee may act by unanimous consent in
writing without a meeting and, subject to the provisions of these By-Laws or
action by the Board of Directors, such Committee, by majority vote of its
members, shall determine the time and place of meetings and the notice required
therefor.

     To the extent specified by the Board of Directors, each Committee may
exercise the authority of the Board of Directors under Section 3.1 of these
By-Laws; provided, however, that a Committee may not:

     (a) authorize distributions;

     (b) approve or recommend to Shareholders any act which is required to be
approved by Shareholders;

     (c) fill vacancies on the Board of Directors or on any of its Committees;

     (d) elect or remove Officers or fix the compensation of any member of the
Committee;

     (e) adopt, amend or repeal these By-Laws;

     (f) approve a plan of merger not requiring Shareholder approval;

     (g) authorize or approve reacquisition of shares, except according to a
general formula or method prescribed by the Board of Directors;

     (h) authorize or approve the issuance or sale, or contract for sale, of
shares or determine the designation and relative rights, preferences and
limitations of a series of shares, except that the Board of Directors may direct
a Committee to fix the specific terms of the issuance or sale or contract for
sale or the number of shares to be allocated to particular employees under an
employee benefit plan; or

     (i) amend, alter, repeal or take action inconsistent with any resolution or
action of the Board of Directors when the resolution or action of the Board of
Directors provides by its terms that it shall not be amended, altered or
repealed by action of a Committee. [BCA Section 8.40]

     Section 3.15 Director Conflict of Interest. If a transaction is fair to the
Corporation at the time it is authorized, approved or ratified, the fact that a
Director of the Corporation is directly or indirectly a party to the transaction
is not grounds for invalidating the transaction.

     In a proceeding contesting the validity of a transaction described in the
preceding paragraph, the person asserting validity has the burden of proving
fairness unless:

     (1) the material facts of the transaction and the Director's interest or
relationship were disclosed or known to the Board of Directors or a Committee of
the Board of Directors and the Board of Directors or Committee authorized,
approved or ratified the transaction by the affirmative votes of a majority of
disinterested Directors, even though the disinterested Directors be less than a
quorum; or

     (2) the material facts of the transaction and the Director's interest or
relationship were disclosed or known to the Shareholders entitled to vote and
they authorized, approved or ratified the transaction without counting the vote
of any Shareholder who was an interested Director.

     The presence of the Director, who is directly or indirectly a party to the
transaction described in the first paragraph of this section, or a Director who
is otherwise not disinterested, may be counted in determining whether a quorum
is present but may not be counted when the Board of Directors or a Committee of
the Board of Directors takes action on the transaction.

     A Director is "indirectly" a party to a transaction if the other party to
the transaction is an entity in which the Director has a material financial
interest or of which the Director is an Officer, Director or General Partner.

                     INDEMNIFICATION OF OFFICERS, DIRECTORS,
                         EMPLOYEES AND AGENTS; INSURANCE

     Section 5.1 Actions Other Than Actions By or in the Right of the
Corporation. The Corporation shall indemnify any of its Directors or Officers
and may indemnify any of its employees and agents who was or is a party, or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the Corporation) by reason of the
fact that he or she or it is or was a Director, Officer, employee or agent of
the Corporation, or who is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by such person in connection with such action, suit or proceeding, if
such person acted in good faith and in a manner he or she or it reasonably
believed to be in, or not opposed to, the best interests of the Corporation and,
with respect to any criminal action or proceeding, had no reasonable cause to
believe his or her or its conduct was unlawful. The termination of any action,
suit or proceeding by judgment, order, settlement, conviction, or upon a plea of
nolo contendere or its equivalent, shall not, of itself, create a presumption
that the person did not act in good faith and in a manner which he or she or it
reasonably believed to be in, or not opposed to, the best interests of the
Corporation or, with respect to any criminal action or proceeding, that the
person had reasonable cause to believe that his or her or its conduct was
unlawful. [BCA Section 8.75(a)]

     Section 5.2 Actions By or in the Right of the Corporation. The Corporation
may indemnify any person who was or is a party, or is threatened to be made a
party to any threatened, pending or completed action or suit by or in the right
of the Corporation to procure a judgment in its favor by reason of the fact that
such person 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, partnership, joint venture, trust or
other enterprise, against expenses (including attorneys' fees) actually and
reasonably incurred by such person in connection with the defense or settlement
of such action or suit, if such person acted in good faith and in a manner he or
she reasonably believed to be in, or not opposed to, the best interests of the
Corporation, provided that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable for negligence or misconduct in the performance of his or her duty to the
Corporation, unless, and only to the extent that, the court in which such action
or suit was brought shall determine upon application that, despite the
adjudication of liability, but in view of all the circumstances of the case,
such person is fairly and reasonably entitled to indemnity for such expenses as
the court shall deem proper. [BCA Section 8.75(b)]

     Section 5.3 Indemnification in Event of Successful Defense. To the extent
that a Director, Officer, employee or agent of the Corporation has been
successful, on the merits or otherwise, in the defense of any action, suit or
proceeding referred to in Sections 5.1 or 5.2, or in defense of any claim, issue
or matter therein, such person shall be indemnified against expenses (including
attorneys' fees) actually and reasonably incurred by such person in connection
therewith. [BCA Section 8.75(c)]

     Section 5.4 Procedures for Indemnification. Any indemnification under
Sections 5.1 and 5.2 (unless ordered by a court) shall be made by the
Corporation only as authorized in the specific case, upon a determination that
indemnification of the Director, Officer, employee or agent is proper in the
circumstances because he or she or it has met the applicable standard of conduct
set forth in said Sections. Such determination shall be made (a) by the Board of
Directors by a majority vote of a quorum consisting of Directors who were not
parties to such action, suit or proceeding, or (b) if such a quorum is not
obtainable, or even if obtainable, if a quorum of disinterested Directors so
directs, by independent legal counsel in a written opinion, or (c) by the
Shareholders. [BCA Section 8.75(d)]

     Expenses incurred in defending a civil or criminal action, suit or
proceeding may be paid by the Corporation in advance of the final disposition of
such action, suit or proceeding, as authorized by the Board of Directors in the
specific case, upon receipt of a written undertaking by or on behalf of the
Director, Officer, employee or agent to repay such amount unless it shall
ultimately be determined that he or she or it is entitled to be indemnified by
the Corporation as authorized in this Article 5. [BCA Section 8.75(e)]

     The indemnification provided by this Article 5 shall not be deemed
exclusive of any other rights to which those seeking indemnification may be
entitled under any By-Law, agreement, vote of Shareholders or disinterested
Directors, or otherwise, both as to action in his or her or its official
capacity and as to action in another capacity while holding such Office, and
shall continue as to a person who has ceased to be a Director, Officer, employee
or agent, and shall inure to the benefit of the heirs, executors and
administrators of such a person. [BCA S8.75(f)]

     If the Corporation has paid indemnity or has advanced expenses to a
Director, Officer, employee or agent, the Corporation shall report the
indemnification or advance in writing to the Shareholders with or before the
notice of the next Shareholders' Meeting. [BCA S8.75(h)]

     For purposes of this Article 5, references to the "Corporation" shall
include, in addition to the surviving corporation, any merging corporation
(including any corporation having merged with a merging corporation) absorbed in
a merger which, if its separate existence had continued, would have had the
power and authority to indemnify its Directors, Officers, and employees or
agents, so that any person who was a director, officer, employee or agent of
such merging corporation, or was serving at the request of such merging
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 Article 5 with respect to the surviving
corporation as such person would have with respect to such merging corporation
if its separate existence had continued. [BCA Section 8.75(i)]

     For purposes of this Article 5, references to "other enterprises" shall
include employee benefit plans; references to "fines" shall include any excise
taxes assessed on a person with respect to an employee benefit plan; and
references to "serving at the request of the Corporation" shall include any
service as a Director, Officer, employee or agent of the Corporation which
imposes duties on, or involves services by, such Director, Officer, employee, or
agent with respect to an employee benefit plan, its participants, or
beneficiaries. A person who acted in good faith and in a manner he or she or it
reasonably believed to be in the best interests of the participants and
beneficiaries of an employee benefit plan shall be deemed to have acted in a

manner "not opposed to the best interest of the Corporation" as referred to in
this Article 5. [BCA Section 8.75(j)]

     Section 5.5 Indemnity Insurance. The Corporation may purchase and maintain
insurance on behalf of any person who is or was a Director, Officer, employee or
agent of the Corporation, or who is or was serving at the request of the
Corporation as a Director, Officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, against any liability
asserted against such person and incurred by such person in any such capacity,
or arising out of his or her status as such, whether or not the Corporation
would have the power to indemnify such person against such liability under the
provisions of this Article 5 or under the provisions of Section 8.75 of the
Illinois Business Corporation Act of 1983. [BCA Section 8.75(g)]

     Section 6.1 Contracts. The Board of Directors may expressly authorize any
Officer or Officers and agent or agents of the Corporation to enter into any
contract or execute and deliver any instrument in the name and on behalf of the
Corporation, and such authority may be general or confined to specific
instances. [BCA Section 8.50]

     Section 6.2 Loans. All loans contracted on behalf of the Corporation and

Section 11.55]

     Section 6.4 Checks, Drafts, Etc. All checks, drafts or other orders for the
payment of money, notes or other evidences of indebtedness issued in the name of

resolution of the Board of Directors.

                            SHARES AND THEIR TRANSFER

     Section 7.1 Consideration for Shares. Shares may be issued for such
consideration as shall be authorized from time to time by the Board of Directors
through action which establishes a price in cash or other consideration, or
both, or a minimum price or a general formula or method by which the price can
be determined. Upon authorization by the Board of Directors, the Corporation may
issue its own shares in exchange for or in conversion of its outstanding shares,
or may distribute its own shares pro rata to its Shareholders or the
Shareholders of one or more


                                       13



                    LIFECARE AMBULANCE SERVICE, INC. BY-LAWS

classes or series to effectuate dividends or splits, and any such transactions
shall not require consideration; provided, that no such issuance of shares of
any class or series shall be made to the holders of shares of any other class or
series unless it is either expressly provided for in the Articles of
Incorporation or authorized by an affirmative vote of the holders of at least a
majority of the outstanding shares of the class or series in which the
distribution is to be made. [BCA Section 6.25]

     Section 7.2 Payment for Shares. The consideration for the issuance of
shares shall be paid, in whole or in part, in money, in other property, tangible
or intangible, or in labor or services actually performed for the Corporation,
as determined by the Board of Directors. When payment of the consideration for
which shares are to be issued shall have been received by the Corporation, such
shares shall be deemed to be fully paid and non-assessable. In the absence of
actual fraud in the transaction, and subject to the provisions of the Business
Corporation Act of 1983, the judgment of the Board of Directors or the
Shareholders, as the case may be, as to the value of the consideration received
for shares shall be conclusive. [BCA Section 6.30]

     Section 7.3 Shares Represented by Certificates. Except as otherwise
provided pursuant to this Article 7, the issued shares of the Corporation shall
be represented by certificates. Certificates shall be signed by the appropriate
corporate Officers and may be sealed with the seal, or a facsimile of the seal,
of the Corporation. In case the seal of the Corporation is changed after the
certificate is sealed with the seal or a facsimile of the seal of the
Corporation, but before it is issued, the certificate may be issued by the
Corporation with the same effect as if the seal had not been changed. If a
certificate is countersigned by a transfer agent or registrar, other than the
Corporation itself or its employee, any other signatures or countersignatures on
the certificate may be facsimiles. In case any Officer of the Corporation, or
any officer or employee of the transfer agent or registrar who has signed, or
whose facsimile signature has been placed upon, such certificate ceases to be an
Officer of the Corporation, or an officer or employee of the transfer agent or
registrar, before such certificate is issued, the certificate may be issued by
the Corporation with the same effect as if the Officer of the Corporation, or
the officer or employee of the transfer agent or registrar, had not ceased to be
such at the date of its issue.

     Every certificate representing shares issued by the Corporation at a time
when the Corporation is authorized to issue shares of more than one class shall
set forth upon the face or back of the certificate a full summary or statement
of all of the designations, preferences, qualifications, limitations,
restrictions and special or relative rights of the shares of each class
authorized to be issued, and, if the Corporation is authorized to issue any
preferred or special class in series, the variations in the relative rights and
preferences between the shares of each such series so far as the same have been
fixed and determined, and the authority of the Board of Directors to fix and
determine the relative rights and preferences of subsequent series. Such
statement may be omitted from the certificate if it shall be set forth upon the
face or back of the certificate that such statement, in full, will be furnished
by the Corporation to any Shareholder upon request and without charge.

     Each certificate representing shares shall also state:

     (a) That the Corporation is organized under the laws of Illinois;


                                       14



                    LIFECARE AMBULANCE SERVICE, INC. BY-LAWS

     (b) The name of the person to whom issued; and

     (c) The number and class of shares, and the designation of the series, if
any, which such certificate represents;

     No certificate shall be issued for any share until such share is fully
paid. [BCA Section 6.35]

     Section 7.4 Uncertificated Shares. The Board of Directors of the
Corporation may provide by resolution that some or all of any or all classes and
series of its shares shall be uncertificated shares, provided that such
resolution shall not apply to shares represented by a certificate until such
certificate is surrendered to the Corporation. Within a reasonable time after
the issuance or transfer of uncertificated shares, the Corporation shall send to
the registered owner thereof a written notice containing the information
required to be set forth or stated on certificates pursuant to this Article 7.
Except as otherwise expressly provided by law, the rights and obligations of the
holders of uncertificated shares and the rights and obligations of holders of
certificates representing shares of the same class and series shall be
identical. [BCA Section 6.35 ]

year of the Corporation shall begin on the first day of January in each year and
end on the last day of December 31 in each year.
