ITEM 2.  TENDER OFFER OF THE BIDDER
 
    This Statement relates to a tender offer by MedTrans Acquisition Co., a
Delaware corporation (the "Purchaser") and an indirect wholly owned subsidiary
of Laidlaw Inc., a Canadian corporation (the "Parent" or "Laidlaw"), disclosed
in a Tender Offer Statement on Schedule 14D-1 (the "Schedule 14D-1") dated
January 10, 1997 to purchase all outstanding shares (the "Shares") of the Common
Stock at a price of $40.00 per Share, net to the seller in cash, without
interest thereon upon the terms and subject to the conditions set forth in the
Offer to Purchase dated January 10, 1997 (the "Offer to Purchase") and the
related Letter of Transmittal (which together constitute the "Offer").
 
    The Offer is being made pursuant to an Agreement and Plan of Merger dated as
of January 6, 1997 (the "Merger Agreement") among the Parent, the Purchaser and
the Company. The Merger Agreement provides that, among other things, as soon as
practicable after the consummation of the Offer and satisfaction or, if
permissible, waiver of the conditions to the Merger, the Purchaser shall be
merged with and into the Company (the "Merger"), the separate corporate
existence of the Purchaser shall cease, and the Company shall continue as the
surviving corporation (the "Surviving Corporation"). A copy of the Merger
Agreement is filed as Exhibit 1 to this Statement and is incorporated herein by
reference.

ITEM 3.  IDENTITY AND BACKGROUND
 
    (a) The name and address of the Company, which is the person filing this
Statement, are set forth in Item 1 above.
 
    (b) Certain contracts, agreements, arrangements or understandings between
the Company and its executive officers, directors and affiliates are described
on pages 11-12, 16 and 18 of the Company's Proxy Statement dated May 9, 1996 for
its 1996 Annual Meeting of Stockholders (the "1996 Proxy Statement"). Pages
11-12, 16 and 18 are filed as Exhibit 2 to this Statement and are incorporated
herein by reference.
 
    In April 1996, David C. Colby entered into an employment agreement with the
Company that entitles him to receive an annual base salary as well as such
bonuses as may be authorized from time to time by the Board of Directors. The
agreement has an initial term of three years, with automatic extensions of one
year added annually unless terminated, and with a covenant-not-to-compete with
the Company for a period of two years following termination of employment. Under
Mr. Colby's employment agreement, if the Company terminates Mr. Colby's
employment agreement other than for cause or if Mr. Colby terminates his
employment for Good Reason (as defined), Mr. Colby will be entitled to a
termination payment approximately equal to his base salary, plus 1.5 times the
greater of (i) any bonus or incentive compensation paid to him for an eighteen
month period or (ii) 50% of his base salary. In addition, all options to
purchase Common Stock which were previously granted to Mr. Colby shall
immediately vest. Annual base salary currently in effect for Mr. Colby is
$283,250.
 
    In December 1996, the Company and one of its wholly-owned subsidiaries, STAT
Healthcare, Inc. ("STAT"), entered into an employment agreement with Russell D.
Schneider, who became a director of the Company in December 1996. Mr.
Schneider's annual base salary is currently $150,000. Mr. Schneider's
 
                                       1
<PAGE>
employment agreement has a term of three years and provides that if his
employment with STAT is terminated other than for cause by STAT within the three
years after December 1996, he will receive his base compensation in effect on
the date prior to termination for an additional period of twelve months and
continuation of coverage and participation in current medical and dental
insurance plans for such twelve month period. In addition, Mr. Schneider's
employment agreement also provides that if Mr. Schneider sells or otherwise
disposes of his shares of Common Stock received by Mr. Schneider in the
acquisition of STAT before the dates specified in the agreement, he is required
to pay to STAT the difference between the average selling price of such shares
and the closing price of the Common Stock on the first date such shares are not
subject to such provisions. The Company expects to release Mr. Schneider from
these provisions in connection with the Offer and the Merger.
 
    David C. Colby and George B. DeHuff have each entered into an agreement with
the Company and Parent relating to his employment with the Company following
consummation of the Offer. Under the terms of these agreements, as an inducement
to remain in their respective positions with the Company following the Offer and
the Merger, Messrs. and DeHuff will each be paid an amount ($841,500 in the case
of Mr. Colby and $817,000 in the case of Mr. DeHuff) on August 31, 1997 if he is
still employed by the Company on that date, provided that if he is terminated
without cause (as defined in the Company's Executive Separation Allowance Plan
(the "Separation Plan")) prior to August 31, 1997 or if he terminates his
employment following the occurrence of certain specified events he will receive
such amount upon such termination and will be entitled to receive certain
specified benefits. In addition, the agreements amend the respective employment
agreements with Messrs. Colby and DeHuff effective upon consummation of the
Offer to (i) increase the annual base salary of each of Messrs. Colby and DeHuff
to $325,000, (ii) provide that each is eligible for an annual performance bonus
with a target of 50% of his base salary, based on quantitative and qualitative
performance factors to be established by the Company, and that he will
participate in any other bonus program that Parent or the Company makes
available for senior executives of the Company, (iii) amend the provisions
relating to severance benefits to be provided under his existing employment
agreements to provide that in the event that he is terminated without cause by
the Company or by him for Good Reason (as defined) he will be entitled to
receive his cash compensation earned to the date of termination plus the greater
of the pro rata portion of his target bonus for the preceding twelve months or
the pro rata portion of 50% of his then current base salary, and, in respect of
any other bonus plan in which he is then participating, an amount that reflects
his achievement of any performance goals under such plan to the date of
termination. The agreements also provide that each of Messrs. Colby and DeHuff
will be granted, effective January 6, 1997, the date the Merger Agreement was
executed, an option to purchase 30,000 shares of Parent's Class B Nonvoting
Shares at an exercise price equal to the closing price of the shares on January
3, 1997, the date preceding the date on which the Merger Agreement was executed
and will be granted, in May 1997, an option to purchase an additional 30,000
shares of Parent's Class B Nonvoting Shares at an exercise price equal to the
fair market value of such shares on the date of grant. Such options will vest in
five equal annual installments commencing on the first anniversary of the date
of grant. Under the agreements, effective upon consummation of the Offer, each
of Messrs. Colby and DeHuff waives his rights under the Separation Plan, except
as otherwise provided in the agreement with respect to continuation of certain
employee benefits following termination of the executive's employment with the
Company without cause or for Good Reason prior to August 31, 1997.
 
    At a meeting of the Board of Directors of the Company held on January 5,
1997, the Board accelerated the vesting of all options to purchase Common Stock,
including options held by executive officers, directors and affiliates of the
Company, effective on the date on which Purchaser purchases shares of Common
Stock pursuant to the Offer. Under the terms of the Merger Agreement, each
holder of an option to purchase Common Stock who executes an agreement to cancel
such option shall be entitled to receive as soon as practicable thereafter from
the Company in consideration for such cancellation an amount in cash (less
applicable withholding taxes) equal to the product of (i) the number of shares
of Common Stock previously subject to such option MULTIPLIED BY (ii) the excess,
if any, of the per share
 
                                       2
<PAGE>
amount paid to holders tendering their shares in the Offer over the exercise
price per share of the Common Stock previously subject to such option.
 
    (c) Except as described below or incorporated herein, to the knowledge of
the Company, as of the date hereof, there exists no material contract,
agreement, arrangement or understanding and no actual or potential conflict of
interest between the Company or its affiliates and (i) the Company, its
executive officers, directors or affiliates or (ii) the Purchaser or its
executive officers, directors or affiliates.
 
INDEMNIFICATION UNDER DELAWARE LAW, THE COMPANY'S CERTIFICATE OF INCORPORATION
  AND BY-LAWS AND THE MERGER AGREEMENT
 
    The Company is a Delaware corporation. Under Delaware law, indemnification
of directors and officers is generally permitted for expenses incurred by them
by reason of their position with the corporation, if the director or officer has
acted in good faith and with the reasonable belief that his conduct was in the
best interest of the corporation. However, Delaware law does not permit a
corporation to indemnify persons against judgments in actions brought by or in
the right of the corporation (although it does permit indemnification in such
situations if approved by the Delaware Court of Chancery and for expenses of
such actions). Article X of the Company's Certificate of Incorporation, as
amended, provides that the Company shall, to the maximum extent permitted under
Delaware law, indemnify and advance expenses to any person who is or was a party
or is threatened to be made a party to any action, suit, proceeding or claim, by
reason of being a director or officer of the Company.
 
    The Company maintains insurance policies that provide for the
indemnification of directors and officers pursuant to the provisions described
above.
 
    The Merger Agreement provides that Parent will cause the Surviving
Corporation to keep in effect the provisions in its Certificate of Incorporation
and By-Laws containing the provisions with respect to indemnification and
exculpation set forth in the Certificate of Incorporation and the By-Laws of the
Company on the date of the Merger Agreement to the fullest extent permitted
under applicable law. These provisions may not be amended, repealed or otherwise
modified for a period of three years from the date of the Merger in any manner
that would adversely affect the rights of those who were directors, officers,
employees or agents of the Company at the date of the Merger, unless such
modification is required by law.
 
    The Merger Agreement provides that the Company shall, to the fullest extent
permitted under applicable law or under the Company's Certificate of
Incorporation or By-Laws, and, after the date of the Merger, the Surviving
Corporation shall, to the fullest extent permitted under applicable law or under
the Surviving Corporation's Certificate of Incorporation or By-Laws, indemnify
and hold harmless, each present and former director, officer or employee of the
Company or any of its subsidiaries (collectively, the "Indemnified Parties")
against any costs or expenses (including attorneys' fees), judgments, fines,
losses, claims, damages, liabilities and amounts paid in settlement in
connection with any claim, action, suit, proceeding or investigation, whether
civil, criminal, administrative or investigative, arising out of or pertaining
to the transactions contemplated by the Merger Agreement, or otherwise with
respect to any acts or omissions occurring at or prior to the date of the
Merger, to the same extent as provided in the Company's Certificate of
Incorporation or By-Laws or any applicable contract or agreement as in effect on
the date of the Merger Agreement, in each case for a period of three years after
the date of the Merger Agreement. In the event of any such claim, action, suit,
proceeding or investigation (whether arising before or after the date of the
Merger), (i) any counsel retained by the Indemnified Parties for any period
after the date of the Merger shall be reasonably satisfactory to the Surviving
Corporation, (ii) after the date of the Merger, the Surviving Corporation shall
pay the reasonable fees and expenses of such counsel, promptly after statements
therefor are received, and (iii) the Surviving Corporation will cooperate in the
defense of any such matter; PROVIDED, HOWEVER, that the Surviving Corporation
shall not be liable for any settlement effected without its written consent
(which consent shall not be unreasonably withheld); and
 
                                       3
<PAGE>
PROVIDED, FURTHER, that, in the event that any claim or claims for
indemnification are asserted or made within such three-year period, all rights
to indemnification in respect of any such claim or claims shall continue until
the disposition of any and all such claims. The Indemnified Parties as a group
may retain only one law firm to represent them with respect to any single action
unless there is, under applicable standards of professional conduct, a conflict
on any significant issue between the positions of any two or more Indemnified
Parties. Such indemnity agreements of Parent and the Surviving Corporation shall
extend, on the same terms to, and shall inure to the benefit of and shall be
enforceable by, each person or entity who controls, or in the past controlled,
any present or former director, officer or employee of the Company or any of its
subsidiaries.
 
    The Merger Agreement provides that the Surviving Corporation shall honor and
fulfill in all respects the obligations of the Company pursuant to
indemnification agreements with the Company's directors and officers existing at
or before the date of the Merger.
 
    Pursuant to the Merger Agreement, for a period of five years after the date
of the Merger, Parent shall cause the Surviving Corporation to maintain in
effect, if available, directors' and officers' liability insurance covering
those persons who are currently covered by the Company's directors' and
officers' liability insurance policy on terms (including the amounts of coverage
and the amounts of deductibles, if any) that are comparable to the terms now
applicable to directors and officers of Parent, or, if more favorable to the
Company's directors and officers, the terms now applicable to them under the
Company's current policies; PROVIDED, HOWEVER, that in no event shall Parent or
the Surviving Corporation be required to expend in excess of 300% of the annual
premium currently paid by the Company for such coverage; and provided further,
that if the premium for such coverage exceeds such amount, Parent or the
Surviving Corporation shall purchase a policy with the greatest coverage
available for such 300% of the annual premium.
 
    Under the Merger Agreement, from and after the Merger, Parent is
guaranteeing the obligations of the Surviving Corporation under the provisions
of the Merger Agreement relating to indemnification and directors' and officers'
liability insurance.
 
THE MERGER AGREEMENT
 
    The following is a summary of certain provisions of the Merger Agreement.
Such summary is qualified in its entirety by reference to the Merger Agreement,
a copy of which is filed herewith as Exhibit 1 and is incorporated herein by
reference. Capitalized terms not otherwise defined in the following summary of
certain provisions of the Merger Agreement have the respective meanings ascribed
to them in the Merger Agreement. In particular, when the term material adverse
effect is used herein it has the meaning as defined in the Merger Agreement.
 
    THE OFFER.  The Merger Agreement provides that the Purchaser will commence
the Offer and that, upon the terms and subject to the prior satisfaction or
waiver of the conditions of the Offer, the Purchaser will purchase all Shares
validly tendered pursuant to the Offer. The Merger Agreement provides that the
Purchaser may in its sole discretion waive, in whole or in part, at any time or
from time to time, any condition (other than the Minimum Condition, which may
not be waived without the prior written consent of the Company), increase the
price per Share payable in the Offer or make any other changes in the terms and
conditions of the Offer; provided that, unless previously approved by the
Company in writing, no change may be made that decreases the price per Share
payable in the Offer, changes the form of consideration payable in the Offer,
reduces the maximum number of Shares to be purchased in the Offer or imposes
conditions to the Offer in addition to those set forth herein. As of December
31, 1996, there were 21,047,345 Shares issued and outstanding, 1,999,180 shares
of Common Stock reserved for issuance under the Company's stock option plans and
agreements and stock purchase plan, 3,311,258 shares of Common Stock reserved
for issuance upon conversion of the Notes, and 3,919,900 shares of Common Stock
issuable in connection with the acquistion of STAT Healthcare, Inc., and that,
except as otherwise
 
                                       4
<PAGE>
disclosed in the Merger Agreement, no other stock of the Company is outstanding
or committed to be issued. Based on this information and assuming all holders of
outstanding options to purchase shares of Common Stock will have entered into
agreements to cancel such options on or prior to the date Purchaser purchases
the Shares pursuant to the Offer, the Company believes that the Minimum
Condition will be satisfied if the Purchaser acquires at least 18,852,335 Shares
in the Offer. Laidlaw has informed the Company that it directly or indirectly
holds 480,000 shares which will not be tendered but will count toward the
satisfaction of the Minimum Condition. Certain other conditions to the Offer are
described in the Offer to Purchase.
 
    THE MERGER.  The Merger Agreement provides that, subject to the terms and
conditions thereof, and in accordance with Delaware Law, the Purchaser shall be
merged with and into the Company as soon as practicable after satisfaction or
waiver of the conditions set forth in the Merger Agreement (the "Effective
Time"). The Merger shall become effective upon the filing of a Certificate of
Merger with the Secretary of State of the State of Delaware (or such later date
as is specified in the Certificate of Merger). As a result of the Merger, the
separate corporate existence of the Purchaser will cease and the Company will
continue as the surviving corporation (the "Surviving Corporation"). In the
Merger, each issued and outstanding Share (other than Shares owned directly or
indirectly by Laidlaw or any of its subsidiaries or by the Company as treasury
stock, and other than Shares owned by stockholders who have properly exercised
rights of appraisal under Delaware Law) will be converted into the right to
receive $40.00 per Share, without interest, and each issued and outstanding
share of common stock of the Purchaser will be converted into one fully paid and
non-assessable share of common stock of the Surviving Corporation.
 
    The Merger Agreement provides that the certificate of incorporation and
by-laws of the Purchaser at the Effective Time will be the certificate of
incorporation and by-laws of the Surviving Corporation until amended in
accordance with applicable law. The Merger Agreement also provides that the
directors of the Purchaser at the Effective Time will be the directors of the
Surviving Corporation, and the officers of the Purchaser at the Effective Time
will be the officers of the Surviving Corporation.
 
    THE COMPANY'S BOARD OF DIRECTORS.  The Merger Agreement provides that,
commencing upon the purchase of Shares pursuant to the Offer, and from time to
time thereafter, Purchaser will be entitled to designate such number of
directors, rounded up to the next whole number, on the Board of Directors of the
Company as will give Purchaser representation on the Board equal to the product
of (i) the total number of directors on the Board and (ii) the percentage that
the number of Shares owned by the Purchaser and its affiliates (including Shares
purchased pursuant to the Offer) bears to the total number of outstanding
Shares, and the Company has agreed, upon request of the Purchaser, promptly
either to increase the size of the Board (and, if necessary, amend the Company's
by-laws to permit such an increase) or to use its reasonable best efforts to
secure the resignations of such number of directors as is necessary to enable
the Purchaser's designees to be elected to the Board and to cause the
Purchaser's designees to be so elected. The Merger Agreement also provides that
following the election or appointment of Purchaser's designees to the Company's
Board of Directors any amendment of the Merger Agreement or any amendment to the
Restated Certificate of Incorporation or Bylaws of the Company inconsistent with
the Merger Agreement, any termination of the Merger Agreement by the Company,
any extension of time for performance of any of the obligations or other acts of
Laidlaw or Purchaser or any waiver of any of the Company's rights under the
Merger Agreement will require the concurrence of a majority of the directors of
the Company then in office who are not designees of the Purchaser or employees
of the Company. The Company's obligation to appoint the Purchaser's designees to
the Board of Directors is subject to Section 14(f) of the Exchange Act and Rule
14f-1 promulgated thereunder.
 
    STOCKHOLDERS MEETING.  Pursuant to the Merger Agreement, the Company will,
if required by applicable law in order to consummate the Merger, duly call and
hold a special meeting of its stockholders (the "Special Meeting") as promptly
as practicable following the acceptance for payment and purchase of Shares by
the Purchaser pursuant to the Offer for the purpose of voting upon the Merger
Agreement, the
 
                                       5
<PAGE>
Merger and related matters. The Board shall recommend approval and adoption of
the Merger Agreement by the Company's stockholders.
 
    INTERIM OPERATIONS.  In the Merger Agreement, the Company has agreed that,
except as otherwise agreed in writing by Laidlaw, prior to the time Purchaser's
designees are elected as directors, the businesses of the Company and its
subsidiaries shall be conducted only in the ordinary course of business
consistent with past practice, the Company will use its reasonable commercial
efforts to preserve substantially intact its business organization, keep
available the services of the present officers, employees and consultants of the
Company and its subsidiaries, and preserve the present relationships of the
Company and it subsidiaries with customers, suppliers, and other persons with
which the Company or any of its subsidiaries has significant business relations.
In addition, except as expressly contemplated by the Merger Agreement or without
the prior written consent of Laidlaw, each of the Company and its subsidiaries
will not:
 
        (a) amend or otherwise change the Certificate of Incorporation or By-
    Laws of the Company or any of its subsidiaries;
 
        (b) issue, sell, pledge, dispose of or encumber, or authorize the
    issuance, sale, pledge, disposition or encumbrance of, any shares of capital
    stock of any class of the Company or any of the Company's subsidiaries, or
    any options, warrants, convertible securities or other rights of any kind to
    acquire any shares of capital stock, or any other ownership interest
    (including, without limitation, any phantom interest) in the Company or any
    of its subsidiaries or affiliates (except for (i) the issuance of shares of
    Company Common Stock issuable pursuant to certain stock options; (ii) the
    grant of options under the Company's stock option plans consistent with past
    practice to purchase up to 50,000 shares of Company Common Stock at the
    market value on the date of grant to newly hired employees (excluding
    executive officers), and the issuance of shares upon exercise thereof, (iii)
    the issuance of shares of Company Common Stock issuable upon conversion of
    the Notes, (iv) the issuance of shares of Company Common Stock issuable to
    participants in the Company's Employee Stock Purchase Plan pursuant to the
    terms thereof, (v) the issuance of shares of Company Common Stock at not
    less than the fair market value thereof in connection with certain permitted
    acquisitions, and (vi) the issuance of shares of Company Common Stock to
    former holders of shares of capital stock of STAT Healthcare, Inc.);
 
        (c) sell, pledge, dispose of or encumber any assets of the Company or
    any of its subsidiaries (except for (i) sales of assets in the ordinary
    course of business and in a manner consistent with past practice, (ii)
    disposition of obsolete or worthless assets, (iii) sales of immaterial
    assets not in excess of $500,000, and (iv) encumbrances on assets to secure
    purchase money financings of equipment and capital improvements and in
    connection with the financing of permitted acquisitions);
 
        (d) (i) declare, set aside, make or pay any dividend or other
    distribution (whether in cash, stock or property or any combination thereof)
    in respect of any of its capital stock, except that a wholly-owned
    subsidiary of the Company may declare and pay a dividend or make advances to
    its parent or the Company, (ii) split, combine or reclassify any of its
    capital stock or issue or authorize or propose the issuance of any other
    securities in respect of, in lieu of or in substitution for shares of its
    capital stock, or (iii) amend the terms or change the period of
    exercisability of, purchase, repurchase, redeem or otherwise acquire, or
    permit any subsidiary to purchase, repurchase, redeem or otherwise acquire,
    any of its securities or any securities of its subsidiaries, including,
    without limitation, shares of Company Stock or any option, warrant or right,
    directly or indirectly, to acquire shares of Company Common Stock, or
    propose to do any of the foregoing; except for the acceleration of options
    pursuant to the terms of the Company stock option plans and the net exercise

inquiries or proposals being referred to herein as an "Acquisition Proposal"),
(ii) engage in negotiations or discussions concerning, or provide any nonpublic
information to any person relating to, any Acquisition Proposal or (iii) agree
to approve or recommend any Acquisition Proposal. Nothing contained in the
Merger Agreement prevents the Board of Directors of the Company from
considering, negotiating, approving and recommending to the stockholders of the
Company, or under certain circumstances providing nonpublic information with
respect to, a bona fide Acquisition Proposal not solicited in violation of the
Merger Agreement, provided the Board of Directors of the Company determines in
good faith (upon written advice of independent counsel) that it is required to

Company Stock Option shall be entitled to receive from the Company, in
consideration for such cancellation, an amount in cash (less applicable
withholding taxes) equal to the product of (i) the number of shares previously
subject to such Company Stock Option multiplied by (ii) the excess, if any, of
the Per Share Amount over the exercise price per share of the Company Common
Stock previously subject to such Company Stock Option. Each Company Stock Option

January 6, 1997 were the end of an "Option Period" (as defined in the Plan)
unless a participant withdraws from the Plan. Payroll deductions under the Plan
not used to purchase shares will be returned to the participants.

investigation or other inquiry that might result in such an action or
proceeding) by any governmental authority, nor shall there be in effect any
judgment, decree or order seeking to prohibit or limit Laidlaw from exercising
all material rights and privileges pertaining to its ownership of the Surviving
Corporation or the ownership or operation by Laidlaw or any of its subsidiaries
of all or a material portion of the business or assets of Laidlaw or any of its
subsidiaries, or seeking to compel Laidlaw or any of its subsidiaries to dispose
of or hold separate all or any material portion of the business or assets of

if the Purchaser shall have (A) terminated the Offer or (B) failed to accept for

case if the Purchaser shall have failed to accept for purchase and pay for
Shares by July 15, 1997 (provided that the right to terminate the Merger

resulted in any of the circumstances described in clauses (A) and (B) before
such date); or (iv) by Laidlaw or the Company, prior to the purchase of Shares
pursuant to the Offer, if the Board of Directors of the Company shall withdraw,
modify or change its approval or recommendation of the Offer, the Merger
Agreement or the Merger in a manner adverse to Laidlaw; (v) by Laidlaw or the
Company, prior to the purchase of Shares pursuant to the Offer, (A) if any

Breach"), PROVIDED, THAT, if such Terminating Breach is curable by the Company
or Laidlaw, as the case may be, through the exercise of its reasonable best
efforts and for so long as the Company or Laidlaw, as the case may be, continues
to exercise such reasonable best efforts, neither Laidlaw nor the Company,
respectively, may terminate the Merger Agreement under this provision.
 
    If the Merger Agreement is terminated by Laidlaw pursuant to its rights
described in clauses (iv) or (v) of the preceding paragraph, to compensate
Laidlaw and the Purchaser for entering into the Merger Agreement, their taking
action to consummate the transactions hereunder and incurring the costs and
expenses related thereto and other losses and expenses, including the foregoing
by Laidlaw of other opportunities, the Company will pay Laidlaw a fee of $17.5
million.
 
ITEM 4.  THE SOLICITATION OR RECOMMENDATION
 
RECOMMENDATION OF THE BOARD OF DIRECTORS.
 
    At a special meeting held on January 5, 1997, the Board of Directors of the
Company (the "Board") approved the Merger Agreement and the transactions
contemplated thereby and determined that the Merger and the Offer, taken
together, are fair to, and in the best interests of, the Company and its
stockholders. THE BOARD UNANIMOUSLY RECOMMENDS THAT HOLDERS OF SHARES ACCEPT THE
OFFER AND TENDER THEIR SHARES PURSUANT TO THE OFFER. Copies of a letter to the
Company's stockholders and a press release communicating such approval and
recommendation are filed as Exhibits 3 and 4, respectively, to this Statement
and are incorporated herein by reference.
 
                                       9

BACKGROUND OF THE MERGER AND THE OFFER.
 
    On October 29, 1996, Paul T. Shirley, the President and Chief Executive
Officer of the Company, and James R. Bullock, the President and Chief Executive
Officer of Laidlaw, met in Denver, Colorado. The two had not previously met, and
the purpose of the meeting was to discuss generally the healthcare
transportation industry and its future. There was no discussion about a
potential transaction between the parties at that time. Subsequent to the
meeting in Denver, during the first week of November, 1996, Laidlaw engaged
Merrill Lynch & Co. to provide advice to it on a prospective transaction with
the Company. During the third week of November, 1996, Merrill Lynch reported to
Laidlaw on the results of its analysis of the publicly available information on
the Company. Thereafter, Laidlaw determined that it was in the best interests of
its stockholders to acquire Shares prior to any discussion with respect to a
potential transaction. 480,000 Shares were purchased by Laidlaw between November
21, 1996 and December 5, 1996 at an aggregated purchase price of $14.4 million.
 
    In December, 1996, Mr. Bullock contacted Mr. Shirley and asked to meet
again. They met on December 13, 1996 in Denver, and Mr. Bullock advised Mr.
Shirley that Laidlaw had completed an extensive analysis of the Company and felt
that it was a good fit with Laidlaw's MedTrans business. Mr. Bullock told Mr.
Shirley that Laidlaw was interested in acquiring the Company. He suggested that
Laidlaw would be willing to make a cash offer or, if some or all of the
Company's stockholders wanted to receive Laidlaw securities, a combination of
cash and preferred stock. Mr. Bullock and Mr. Shirley discussed the
opportunities for the two combined businesses. Although Mr. Bullock suggested
that Mr. Shirley could have a role in the combined business, Mr. Shirley
deferred those discussions until after all other terms of the proposed
combination were fully determined. Mr. Bullock advised Mr. Shirley that
Laidlaw's analysis suggested that a fair price for the Company would be in the
range of $37.00 to $38.00 per share. Mr. Shirley suggested that a price closer
to $44.00 per share would be appropriate.
 
    On December 16, 1996, the Company's Board of Directors held a special
meeting by conference telephone to discuss the negotiations with Laidlaw. At the
meeting, Mr. Shirley described his conversations with representatives of Laidlaw
and informed the Board that Laidlaw would possibly be willing to pay $40 per
share for the Company's outstanding shares. The Board instructed Mr. Shirley to
continue discussions with Laidlaw.
 
    On December 16, 1996, Mr. Shirley advised Mr. Bullock that while there was a
genuine interest in pursuing a merger with Laidlaw, the purchase price would
need to be in the range of $42.00 to $44.00. Mr. Bullock advised Mr. Shirley
that the absolute "top price" Laidlaw was willing to pay was $40.00 per share.
On December 17 and 18, 1996, the Company's Board of Directors held special
meetings by conference telephone. At the meetings, Mr. Shirley informed the
Board as to the status of negotiations with Mr. Bullock. Mr. Shirley indicated
that he had been informed by Mr. Bullock $40.00 per share was the highest price
Laidlaw was willing to pay. The Board instructed Mr. Shirley to continue
discussions with Laidlaw. There were various conversations between Mr. Bullock
and Mr. Shirley in which they discussed their valuation issues and attempted to
agree upon a per share price. Ultimately these discussions led to an agreement
of $40.00 per share, subject to satisfactory resolution of the other significant
transaction issues.
 
    Also as a result of this discussion between Mr. Bullock and Mr. Shirley,
Laidlaw and the Company entered into a confidentiality agreement on December 23,
1996. The confidentiality agreement also provided for a one-year standstill on
purchases of Company stock and similar transactions, with certain exceptions.
Pursuant to that confidentiality agreement Laidlaw and its advisors were
provided access to various due diligence materials and Laidlaw performed
diligence to confirm its prior analysis of the Company. On December 20, 1996,
counsel for the Company distributed a draft Agreement and Plan of Merger to
Laidlaw.
 
    On January 3, 1997, the Company's Board of Directors met at a special
meeting. At the meeting, the Board received presentations from management and
from the Company's legal and financial advisors. The Company's management
reviewed the status of negotiations with Laidlaw with respect to the proposed
 
                                       10
<PAGE>
transaction. Ropes & Gray, counsel to the Company, reviewed the Board's
fiduciary duties, and Smith Barney presented its analysis of the proposed
consideration to be received by the Company's stockholders. Ropes & Gray also
reviewed the terms and conditions of the proposed Agreement and Plan of Merger.
Following the presentations of the Board, management and the Company's advisors
discussed the proposed transaction.
 
    In the evening of January 5, 1997, after completion of the negotiations over
the proposed Agreement and Plan of Merger, the Board of Directors of the Company
held a special meeting by conference phone to review, with the advice and
assistance of the Company's financial and legal advisors, the proposed Agreement
and Plan of Merger, and the transaction contemplated thereby, including the
Offer and the Merger. At the meeting, Mr. Shirley described the outcome to the
Board of the final negotiations with Laidlaw with respect to the substantive
terms of the proposed Agreement and Plan of Merger. Smith Barney updated its
analysis presented to the Board at the January 3 meeting of the Board and
delivered its oral opinion to the Board (which was subsequently confirmed by
delivery of a written opinion dated January 6, 1997) to the effect that, as of
such date and based upon and subject to certain matters stated in such opinion,
the cash consideration of $40.00 per share to be received by holders of shares
(other than Laidlaw and its affiliates) in the Offer and the Merger, taken
together, was fair, from a financial point of view, to such holders. Following a
number of questions from, and discussions among, the directors, the Company's
Board of Directors (i) approved the Merger Agreement and the transactions
contemplated thereby and authorized the execution and delivery thereof, (ii)
determined that the Offer and the Merger, taken together, are fair to, and in
the best interests of, the Company and its stockholders, and (iii) recommended
that the Company's stockholders accept the Offer and tender their shares to
Purchaser.
 
    During the period from December 30, 1996, through January 6, 1997, the
Company and Laidlaw negotiated the Merger Agreement and the terms of the Offer.
 
    The Board of Directors of Laidlaw approved the transaction on January 6,
1997, and the Board of Directors of the Company, after discussing the
transaction on several occasions, approved the transaction on January 5, 1997.
 
    On Sunday, January 5, 1997, representatives of the Company and Laidlaw
completed their negotiations of all substantive terms of the Merger Agreement.
On January 5, 1997, the Board of Directors of the Company met and approved the
Offer, the Merger Agreement and related matters. On January 6, 1997, the Boards
of Directors of Laidlaw and Purchaser also took the steps required under the
corporate and securities laws to approve the Offer, the Merger and the Merger
Agreement. Laidlaw, the Purchaser and the Company executed the Merger Agreement
in the afternoon on January 6, 1997. On January 6, 1997, after the closing of
trading, Laidlaw and the Company separately announced the transaction. On
January 10, 1997, Purchaser commenced the Offer.
 
    To the extent any of the foregoing background information describes events
to which the Company was not a party, it is based upon information provided by
Laidlaw.
 
    The Company issued the following press release on January 6, 1997:

FOR IMMEDIATE RELEASE
 
                               LAIDLAW TO ACQUIRE
                        AMERICAN MEDICAL RESPONSE, INC.
 
              MERGER WILL COMBINE TOP TWO AMBULANCE COMPANIES IN U.S.
 
JANUARY 6, 1997 -- AURORA, COLORADO -- American Medical Response, Inc.
(NYSE:EMT) announced today that it had signed a definitive agreement through
which Laidlaw Inc. (NYSE:LDWB) will acquire American Medical Response.
 
According to the terms of the merger agreement, Laidlaw will commence a tender
offer to acquire 100 percent of American Medical Response's outstanding shares
for $40 per share, or an equity value of approximately of $1.12 billion. The
transaction is expected to close in February, subject to a tender of a minimum
of two-thirds of American Medical Response's outstanding shares, required
regulatory approvals, and other customary conditions. American Medical Response
currently has approximately 28 million fully diluted common shares outstanding.
 
Laidlaw plans to merge its San Diego, California-based MedTrans ambulance
services unit with American Medical Response. The combined entity will operate
as American Medical Response, Inc. and will remain headquartered in Aurora,
Colorado. Paul T. Shirley, currently Chief Executive Officer of American Medical
Response, will continue in that role.
 
"This transaction represents a significant realization of value for our
shareholders," said Paul T. Shirley, Chief Executive Officer. "American Medical
Response and MedTrans are two highly successful medical transportation providers
sharing a common view of the future of emergency medical services. The
combination will create an organization with even greater operating efficiencies
and improved service for our patients. As a combined entity, we will be well
positioned to expand the scope of emergency and urgent care services offered to
municipalities and health care payors."
 
"We have known and respected the management of MedTrans for the past several
years," Mr. Shirley continued. "We plan to capitalize on the experience of both
executive teams as we grow the new company."
 
Since its initial public offering in 1992, American Medical Response has
acquired more than 70 ambulance providers. MedTrans, acquired by Laidlaw in
mid-1993, has acquired 80 ambulance companies and currently operates in 23
states. Both companies provide a variety of emergency and non-emergency medical
transportation and related services to municipalities, health care payors, and
individuals. Upon completion of the merger, approximately 40% of Laidlaw's total
revenue will be derived from medical transportation and related services.
 
American Medical Response's Board of Directors received a fairness opinion
regarding the merger from Smith Barney. Merrill Lynch & Co. is acting as the
financial advisor to Laidlaw for the transaction.
 
American Medical Response is the nation's leading provider of emergency and
non-emergency medical transportation services, with operations in 28 states and
over 12,000 employees. Laidlaw, Inc. is a major provider of transportation and
environmental services to municipalities and industries through the United
States and Canada.

    The Purchaser commenced the Offer on January 10, 1997.
 
REASONS FOR THE RECOMMENDATION OF THE COMPANY'S BOARD OF DIRECTORS.
 
    In light of the Board's review of the Company's competitive and financial
position, recent operating results and prospects, the Board determined that the
Offer and the Merger, taken together, are fair to, and in the best interests of,
the Company and its stockholders. In making such recommendation and in approving
the Merger Agreement and the transactions contemplated thereby, the Board
considered a number of factors, including, but not limited to, the following:
 
    (i) the terms and conditions of the Merger Agreement;
 
    (ii) the views expressed by management of the Company (at the Board meetings
on January 3, 1997 and January 5, 1997 and at several previous Board meetings)
regarding the financial condition, results of operations, business and prospects
of the Company, including the prospects of the Company if the Company were to
remain independent;
 
   (iii) the recent trading price of the shares of Common Stock and that the
$40.00 per Share to be paid in the Offer and as the consideration in the Merger
represents a premium of approximately 19% over the $33.625 closing sale price
for the Shares on the New York Stock Exchange on January 3, 1997, the last
trading day prior to the public announcement of the execution of the Merger
Agreement, and a premium of approximately 36% over the $29.50 closing sale price
for the Shares on the New York Stock Exchange one month prior to January 6,
1997;
 
    (iv) the views expressed by management and the Board's conclusion that it
was not likely that any other party would consider a transaction that was more
favorable to the Company and its stockholders;
 
    (v) the financial presentations of Smith Barney at the January 3 and January
5, 1997 Board meetings and the oral opinion of Smith Barney delivered to the
Board at the January 5, 1997 Board meeting (which opinion was subsequently
confirmed by delivery of a written opinion dated January 6, 1997) to the effect
that, as of such date and based upon and subject to certain matters stated in
such opinion, the cash consideration of $40.00 per Share to be received by
holders of Shares (other than Parent and its affiliates) in the Offer and the
Merger, taken together, was fair, from a financial point of view, to such
holders. Smith Barney's opinion is directed only to the fairness, from a
financial point of view, of the cash consideration to be received in the Offer
and the Merger to holders of Shares (other than Parent and its affiliates) and
is not intended to constitute, and does not constitute, a recommendation as to
whether any stockholder should tender Shares pursuant to the Offer. A copy of
the opinion of Smith Barney is attached hereto as Annex II to this Schedule
14D-9 and is incorporated herein by reference. STOCKHOLDERS ARE URGED TO READ
THE OPINION OF SMITH BARNEY CAREFULLY AND IN ITS ENTIRETY;
 
    (vi) the Merger Agreement permits the Board, in the exercise of its
fiduciary duties, to furnish nonpublic information and data, and enter into
discussions and negotiations, in connection with an unsolicited acquisition
proposal and recommend an unsolicited acquisition proposal to the Company's
stockholders;
 
   (vii) the Merger Agreement permits the Board, in the exercise of its
fiduciary duties, to terminate the Merger Agreement in favor of an alternative
acquisition proposals; upon such termination, the Company shall pay Parent a fee
of $17,500,000 (representing approximately 1.46% of the total value of the
consideration to be paid in the Offer and the Merger); and
 
  (viii) the transactions contemplated by the Merger Agreement provided for an
all cash payment to shareholders, with no financing condition.
 
                                       13
<PAGE>
    The Board did not assign relative weights to the above factors or determine
that any factor was of particular importance. Rather, the Board viewed its
position and recommendations as being based on the totality of the information
presented to and considered by it.
 
    The Board recognized that, while the consummation of the Offer gives the
Company's stockholders the opportunity to realize a significant premium over the
price at which the Shares were traded prior to the public announcement of the
Offer, tendering in the Offer would eliminate the opportunity for such
stockholders to participate in the future growth and profits of the Company. The
Board believes that the loss of the opportunity to participate in the growth and
profits of the Surviving Corporation was reflected in the Offer price of $40.00
per Share. The Board also recognized that there can be no assurance as to the
level of growth or profits to be attained by the Surviving Corporation in the
future.
 
    It is expected that, if the Shares are not purchased by Parent in accordance
with the terms of the Offer or if the Merger is not consummated, the Company's
current management, under the general direction of the Board, will continue to
manage the Company as an ongoing business.

    This Information Statement, which is being mailed on or about January 10,
1997 to the holders of shares of the common stock, par value $.01 per share (the
"Common Stock") of American Medical Response, Inc., a Delaware corporation (the
"Company"), is being furnished in connection with the designation by MedTrans
Acquisition, Inc., a Delaware corporation (the "Purchaser") and a wholly owned
subsidiary of Laidlaw Inc., a Canadian corporation (the "Parent"), of persons
(the "Purchaser Designees") to the Board of Directors of the Company (the
"Board"). Such designation is to be made pursuant to an Agreement and Plan of
Merger dated as of January 6, 1997 (the "Merger Agreement") among the Company,
the Parent and the Purchaser.
 
    Pursuant to the Merger Agreement, among other things, the Purchaser
commenced a cash tender offer on January 10, 1997 to purchase all of the issued
and outstanding shares (the "Shares") of Company Stock at a price of $40.00 per
Share, net to the seller in cash, as described in the Purchaser's Offer to
Purchase dated January 10, 1997 and the related Letter of Transmittal (which
Offer to Purchase and related Letter of Transmittal together constitute the
"Offer"). The Offer is scheduled to expire at 12:00 midnight on Friday, February
7, 1997, unless extended. The Offer is subject to, among other things, the
condition that a number of Shares representing not less than two-thirds of the
Company's outstanding voting power on a fully diluted basis being validly
tendered prior to the expiration of the Offer and not withdrawn (the "Minimum
Condition"). The Merger Agreement also provides for the merger (the "Merger") of
the Purchaser with and into the Company as soon as practicable after
consummation of the Offer. Following the consummation of the Merger (the
"Effective Time"), the Company will be the surviving corporation (the "Surviving
Corporation") and a wholly owned subsidiary of the Parent. In the Merger, each
Share issued and outstanding immediately prior to the Effective Time (other than
Shares held in the treasury of the Company or by the Parent, the Purchaser, or
any indirect or direct wholly owned subsidiary of the Parent or the Company, all
of which will be canceled) will be converted into the right to receive cash in
an amount of $40.00.
 
    Following the election or appointment of the Purchaser Designees and prior
to the Effective Time, any amendment of the Merger Agreement or any amendment to
the Restated Certificate of Incorporation or By-laws of the Company inconsistent
with the Merger Agreement, any termination of the Merger Agreement by the
Company, any extension by the Company of the time for the performance of any of
the obligations or other acts of Parent or Purchaser or any waiver of any of the
Company's rights thereunder shall require the concurrence of a majority of the
directors of the Company then in office who are not designees of Purchaser or
employees of the Company.

    The terms of the Merger Agreement, a summary of the events leading up to the
Offer and the execution of the Merger Agreement and other information concerning

Solicitation/Recommendation Statement on Schedule 14D-9 of the Company (the
"Schedule 14D-9") with respect to the Offer, copies of which are being delivered
to stockholders of the Company contemporaneously herewith. Certain other
documents (including the Merger Agreement) were filed with the Securities and
Exchange Commission (the "SEC") as exhibits to the Schedule 14D-9 and as
exhibits to the Tender Offer Statement on Schedule 14D-1 of the Purchaser and
Parent (the "Schedule 14D-1"). The exhibits to the Schedule 14D-9 and the

regional offices of and public reference facilities maintained by the SEC
(except that the exhibits thereto cannot be obtained from the regional offices
of the SEC) in the manner set forth in Sections 7 and 17 of the Offer to
Purchase.
 
    No action is required by the stockholders of the Company in connection with
the election or appointment of the Purchaser Designees to the Board. However,
Section 14(f) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), requires the mailing to the Company's stockholders of the information set
forth in this Information Statement prior to a change in a majority of the
Company's directors otherwise than at a meeting of the Company's stockholders.
 
    The information contained in this Information Statement concerning the
Parent, the Purchaser and the Purchaser Designees has been furnished to the
Company by such persons, and the Company assumes no responsibility for the
accuracy or completeness of such information. The Schedule 14D-1 indicates that

RIGHT TO DESIGNATE DIRECTORS; THE PURCHASER DESIGNEES
 
    The Merger Agreement provides that, promptly upon the purchase by Purchaser
of Shares pursuant to the Offer and from time to time thereafter, Purchaser

of directors on the Board (giving effect to the election of any additional
directors pursuant to the Merger Agreement) and (ii) the percentage that the
number of Shares owned by Purchaser and its affiliates (including any Shares
purchased pursuant to the Offer) bears to the total number of outstanding
Shares, and the Company shall, upon request by Purchaser, promptly either
increase the size of the Board (and shall if necessary, amend the Company's
By-Laws to permit such an increase) or use its reasonable best efforts to secure
the resignation of such number of directors as is necessary to enable
Purchaser's designees to be elected to the Board and shall cause Purchaser's
designees to be so elected. The Merger Agreement also provides that, promptly
upon request by Purchaser, the Company will use its reasonable best efforts to
cause persons designated by Purchaser to constitute the same percentage as the
number of Purchaser's designees to the Board bears to the total number of
directors on the Board on (i) each committee of the Board, (ii) each board of
directors or similar governing body or bodies of each subsidiary of the Company
designated by Purchaser and (iii) each committee of each such board or body.

each committee meeting attended. Directors are reimbursed for their reasonable
expenses in attending board and committee meetings. Directors who are not

immediately vest. Base salaries for 1996 are: Mr. Shirley -- $300,000, Mr. Colby
- -- $275,000 and Mr. DeHuff -- $250,000.
 
CHANGE-IN-CONTROL ARRANGEMENTS
 
    The Company maintains an Executive Separation Allowance Plan (the
"Separation Plan") under which a participating executive is entitled to certain
benefits if, within 90 days following a change in control of the Company, the
executive is terminated other than for cause or if the executive terminates his
employment for good reason. Good reason includes a major reduction in the
executive's responsibilities, a significant reduction in base salary or total
benefits or a relocation outside of 50 miles from the executive's principal
location of employment. The terminated executive is entitled to a cash payment
equal to a designated multiple of the sum of his highest annual base salary
during the last five years and the highest annual bonus during the last three
years. In addition, the executive will receive one year's life insurance
coverage in an amount equal to two times his highest annual base salary during
the previous five years and
 
                                      I-10
<PAGE>
medical and dental coverage for one year. All stock options held by the
executive will also become exercisable. Messrs. Shirley and DeHuff participate
in the Separation Plan and their designated salary and bonus multiples are 2.99
and 2.00, respectively.
 
SEVERANCE AND CONSULTING ARRANGEMENTS
 
    Beginning in 1996, Mr. Verrochi ceased being a full-time employee of the
Company. In connection with his change in status and the cancellation of his
then existing employment contract, Mr. Verrochi executed a severance agreement
and the Company agreed to make a lump sum payment to him of $952,000 and to
accelerate the exercisability of stock options covering 96,000 shares of Common
Stock held by Mr. Verrochi. Mr. Verrochi has agreed not to compete with the
Company for a period of two years.
 
    Beginning in April 1996, Mr. Puopolo ceased being a full-time employee of
the Company. In connection with his change in status and the cancellation of his
then existing employment contract, Mr. Puopolo executed a severance agreement
and the Company agreed to make a lump sum payment to him of $802,000 and to
accelerate the exercisability of stock options covering 92,000 shares of Common
Stock held by Mr. Puopolo. Mr. Puopolo has agreed not to compete with the
Company for a period of two years. Mr. Puopolo remains as member of the Board of
Directors.
 
    The Company has also entered into consulting agreements with Exel Holdings
Ltd., a company owned by Messrs. Verrochi and Puopolo, to provide consulting
services in connection with the Company's acquisition program. Payments under
the consulting agreements, each of which has a term of one year, in the
aggregate are $20,000 per acquisition up to a maximum of $200,000.
 
    In connection with Mr. Paolella's termination of active employment with the
Company, the Company entered into a severance arrangement with him under which
the Company agreed to make to him a lump sum payment of $252,700 and to
accelerate the exercisability of stock options covering 8,000 shares of Common
Stock that Mr. Paolella holds. Mr. Paolella has agreed not to compete with the
Company for a period of two years.
 
    Until December 1995 the Company had been paying to James E. McGrath a
monthly consulting retainer of $5,600 in connection with services he performed.
Beginning in 1996 the Company ceased paying the retainer, although Mr. McGrath
will remain available on an hourly basis if requested by the Company. In
connection with this restructuring of this consulting arrangement the Company
agreed to make a lump sum payment to Mr. McGrath of $134,400.
 
CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
    The Company leases two ambulance stations in Santa Cruz, California from
Paul T. Shirley. The aggregate amount of lease payments for these properties
incurred by the Company in 1995 was approximately $59,000.
 
    The Company leases its administrative facility in New Haven, Connecticut
from P&J Realty, a partnership in which Joseph R. Paolella is a partner. The
lease and related real estate tax payments paid by the Company to P&J Realty for
this property in 1995 totaled approximately $423,000. On March 31, 1996, the
Company made a payment to P&J Realty of $527,403 which represented the
discounted present value of future payments under the lease in excess of the
fair market value and the then current version of the lease was canceled. The
Company has entered into a new lease which provides for annual base rent of
$290,940 during the initial term with an increase to $339,430 seventeen months
after the commencement of any renewal period. The new lease is for five years
and allows either party to renew for an additional five-year period.
 
    The Company has leased its administrative facility in Gulfport, Mississippi
from Mr. Rester. The Company paid $163,000 in lease payments on this property
during 1995. The lease for this property has a term of five years and expires in
January 1999, with an option for the Company to extend the term for an
 
                                      I-11
<PAGE>
additional five-year period. The lease provides for annual rent of approximately
$131,300. Mr. Rester has expanded the facility at the Company's request and rent
payments when approved for the new facilities will increase the annual rent by
approximately $40,800 annually to annual rent of approximately $172,100.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    Messrs. Thompson, Hammond and Michael A. Baker, none of whom is or was an
executive officer or employee of the Company, served on the Compensation
Committee during 1995. The Company is a party to a consulting agreement with
DECCS, Inc., a company owned by a trust for the benefit of Mr. Baker's children,
pursuant to which Mr. Baker provides certain merger and acquisition advice as
required by the Company. Under that Agreement, DECCS is paid monthly at the rate
of $75,000 per year. During 1995, the Company paid DECCS approximately $90,000
pursuant to the consulting agreement.
 
COMPLIANCE WITH SECTION 16(a) OF THE EXCHANGE ACT
 
    Section 16(a) of the Exchange Act requires the Company's directors and
executive officers, and persons who own more than ten percent of a registered
class of the Company's equity securities, to file with the Securities and
Exchange Commission initial reports of ownership and reports of changes in
ownership of Common Stock and other equity securities of the Company. Officers,
directors and greater-than-ten-percent shareholders are required by SEC
regulation to furnish the Company with copies of all Section 16(a) forms they
file.
 
    To the Company's knowledge, based solely on a review of the copies of such
reports furnished to the Company, during the fiscal year ended December 31,
1996, all Section 16(a) filing requirements applicable to its officers,
directors and greater-than-ten-percent beneficial owners were complied with.

The Board of Directors
American Medical Response, Inc.
2821 South Parker Road
Aurora, Colorado 80014
 
Members of the Board:
 
    You have requested our opinion as to the fairness, from a financial point of
view, to the holders of the common stock of American Medical Response, Inc.
("AMR") of the consideration to be received by such holders pursuant to the
terms and subject to the conditions set forth in the Agreement and Plan of
Merger, dated as of January 6, 1997 (the "Merger Agreement"), by and among
Laidlaw Inc. ("Laidlaw"), MedTrans Acquisition Co., a wholly owned subsidiary of
Laidlaw ("Acquisition"), and AMR. As more fully described in the Merger
Agreement, (i) Laidlaw and Acquisition will make a tender offer to purchase all
outstanding shares of the common stock, par value $0.01 per share, of AMR (the
"AMR Common Stock") at a purchase price of $40.00 per share, net to the seller
in cash (the "Tender Offer") and (ii) subsequent to the Tender Offer,
Acquisition will be merged with and into AMR (the "Merger" and, together with
the Tender Offer, the "Transaction") and each outstanding share of AMR Common
Stock not previously tendered will be converted into the right to receive $40.00
in cash.
 
    In arriving at our opinion, we reviewed the Merger Agreement and held
discussions with certain senior officers, directors and other representatives
and advisors of AMR concerning the business, operations and prospects of AMR. We
examined certain publicly available business and financial information relating
to AMR as well as certain financial forecasts and other information and data for
AMR which were provided to or otherwise discussed with us by the management of
AMR. We reviewed the financial terms of the Transaction as set forth in the
Merger Agreement in relation to, among other things: current and historical
market prices and trading volumes of AMR Common Stock; the historical and
projected earnings and other operating data of AMR; and the capitalization and
financial condition of AMR. We considered, to the extent publicly available, the
financial terms of similar transactions recently effected which we considered
relevant in evaluating the Transaction and analyzed certain financial, stock
market and other publicly available information relating to the businesses of
other companies whose operations we considered relevant in evaluating those of
AMR. In addition to the foregoing, we conducted such other analyses and
examinations and considered such other financial, economic and market criteria
as we deemed appropriate in arriving at our opinion.
 
    In rendering our opinion, we have assumed and relied, without independent
verification, upon the accuracy and completeness of all financial and other
information and data publicly available or furnished to or otherwise reviewed by
or discussed with us. With respect to financial forecasts and other information
and data provided to or otherwise reviewed by or discussed with us, we have been
advised by the management of AMR that such forecasts and other information and
data were reasonably prepared on bases reflecting the best currently available
estimates and judgments of the management of AMR as to the future financial
performance of AMR. We have not made or been provided with an independent
evaluation or appraisal of the assets or liabilities (contingent or otherwise)
of AMR nor have we made any
 
                                      II-1
<PAGE>
physical inspection of the properties or assets of AMR. In connection with our
engagement, we were not requested to, and did not, solicit third party
indications of interest in acquiring all or a part of AMR. Our opinion is
necessarily based upon information available to us, and financial, stock market
and other conditions and circumstances existing and disclosed to us, as of the
date hereof.
 
    Smith Barney has been engaged to render financial advisory services to AMR
in connection with the proposed Transaction and will receive a fee for such
services, a significant portion of which is contingent upon the consummation of
the Transaction. We also will receive a fee upon the delivery of this opinion.
In the ordinary course of our business, we and our affiliates may actively trade
or hold the securities of AMR and Laidlaw for our own account or for the account
of our customers and, accordingly, may at any time hold a long or short position
in such securities. We have in the past provided financial advisory and
investment banking services to AMR unrelated to the proposed Transaction, for
which services we have received compensation. In addition, we and our affiliates
(including Travelers Group Inc. and its affiliates) may maintain relationships
with AMR and Laidlaw.
 
    Our advisory services and the opinion expressed herein are provided for the
information of the Board of Directors of AMR in its evaluation of the proposed
Transaction, and our opinion is not intended to be and does not constitute a
recommendation to any stockholder as to whether or not such stockholder should
tender shares of AMR Common Stock in the Tender Offer or how such stockholder
should vote on the proposed Merger. Our opinion may not be published or
otherwise used or referred to, nor shall any public reference to Smith Barney be
made, without our prior written consent.
 
    Based upon and subject to the foregoing, our experience as investment
bankers, our work as described above and other factors we deemed relevant, we
are of the opinion that, as of the date hereof, the cash consideration to be
received by the holders of AMR Common Stock (other than Laidlaw and its
affiliates) in the Transaction is fair, from a financial point of view, to such
holders.
 
Very truly yours,
 
SMITH BARNEY INC.

                          AGREEMENT AND PLAN OF MERGER

     THIS AGREEMENT AND PLAN OF MERGER, dated as of January 6, 1997, is among
American Medical Response, Inc., a Delaware corporation (the "Company"), Laidlaw
Inc., a Canadian corporation ("Parent") and MedTrans Acquisition Co., a Delaware
corporation and a wholly owned subsidiary of Parent ("Acquisition").

     WHEREAS, the Board of Directors of Parent, Acquisition and the Company have
each approved the acquisition of the Company by Parent upon the terms and
subject to the conditions set forth in this Agreement;

     WHEREAS, in furtherance thereof, it is proposed that Acquisition shall make
a tender offer to acquire all outstanding shares (the "Shares") of common stock,
par value $0.01 per share, of the Company (the "Common Stock") for a cash amount
of $40.00 per Share (such amount, or any greater amount per Share paid pursuant
to the tender offer, being hereinafter referred to as the "Per Share Amount") in
accordance with the terms and subject to the conditions provided for herein (the
"Offer");

     WHEREAS, the Board of Directors of the Company (the "Board") has (i)
determined that the consideration to be paid for each Share in the Offer and the
Merger (as defined below) is fair to and in the best interests of the
stockholders of the Company and (ii) approved this Agreement and the
transactions contemplated hereby and resolved to recommend acceptance of the
Offer and approval and adoption of this Agreement by the stockholders of the
Company; and

     WHEREAS, the Boards of Directors of Parent and Acquisition have each
approved the merger (the "Merger") of Acquisition with and into the Company
following the Offer in accordance with the Delaware General Corporation Law (the
"Delaware Law") upon the terms and subject to the conditions set forth herein.

     NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements herein contained, and intending to be legally bound hereby, the
Company, Parent and Acquisition hereby agree as follows:
<PAGE>

                                   ARTICLE I

                                   THE OFFER

     SECTION 1.1  The Offer.

     (a)  Commencement.  Provided that this Agreement shall not have been
terminated in accordance with Section 8.1, as promptly as practicable, but in
any event within five business days of the public announcement of the terms of
this Agreement, Acquisition shall commence the Offer.  The obligation of
Acquisition to accept for payment and pay for Shares tendered pursuant to the
Offer shall be subject to the condition that a number of Shares representing not
less than two-thirds of the Company's outstanding voting power (assuming the
exercise of all outstanding options to purchase shares of Common Stock the
holders of which have not entered into an agreement to cancel such options as
described in Section 2.6(c)(i) and the conversion of all of the Company's 5 1/4%
Convertible Subordinated Notes due February 1, 2001 (the "Notes")) shall have
been validly tendered and not withdrawn prior to the expiration date of the
Offer (the "Minimum Condition"), and the obligation of Acquisition to accept for
payment and pay for Shares tendered pursuant to the Offer shall be subject to
the other conditions set forth in Annex A hereto.  It is agreed that the Minimum
Condition and the other conditions set forth in Annex A hereto are for the sole
benefit of Acquisition and may be asserted by Acquisition regardless of the
circumstances giving rise to any such condition unless Parent, Acquisition or
their affiliates shall have caused the circumstances giving rise to such
condition.  Acquisition expressly reserves the right in its sole discretion to
waive, in whole or in part, at any time or from time to time, any such condition
(other than the Minimum Condition, which may not be waived without the prior
written consent of the Company), to increase the price per Share payable in the
Offer or to make any other changes in the terms and conditions of the Offer;
provided that, unless previously approved by the Company in writing, no change
may be made that decreases the price per Share payable in the Offer, changes the
form of consideration payable in the Offer, reduces the maximum number of Shares
to be purchased in the Offer or imposes conditions to the Offer in addition to
those set forth in Annex A hereto.  Acquisition covenants and agrees that,
subject to the conditions of the Offer set forth in Annex A hereto, Acquisition
shall accept for payment and pay for Shares which have been validly tendered and
not withdrawn pursuant to the Offer as soon as it is permitted to do so under
applicable law; provided that, if the number of Shares that have been validly
tendered and not withdrawn represent less than 90% of the Company's outstanding
voting power (calculated as described above), Acquisition may extend the Offer
up to the tenth business day following the date on which all conditions to the
Offer shall first have been satisfied or waived.  The Per Share Amount payable
in the Offer shall be paid net to the seller in cash, upon the terms and subject
to the conditions of the Offer.  Acquisition agrees that if all conditions set
forth in Annex A are not satisfied on the initial expiration date of the Offer,
Acquisition shall extend (and re-extend) the Offer through April 15, 1997 to
provide time to satisfy such conditions; provided that, if Acquisition shall not
have purchased Shares pursuant to the Offer prior to April 15, 1997 as the
result of the receipt by the Company of an

                                      -2-
<PAGE>

Acquisition Proposal (as defined below) or as a result of a failure of the
applicable waiting period under the HSR Act (as defined below) to expire or the
failure to obtain any necessary governmental or regulatory approvals,
Acquisition shall extend (and re-extend) the Offer through July 15, 1997.

     (b) Filing Offer Documents.  As soon as practicable on the date of
commencement of the Offer, Parent and Acquisition shall file with the Securities
and Exchange Commission (the "SEC") a Tender Offer Statement on Schedule 14D-1
with respect to the Offer which will contain the offer to purchase and form of
the related letter of transmittal (together with any supplements or amendments
thereto, the "Offer Documents").  Parent, Acquisition and the Company each
agrees promptly to correct any information provided by it for use in the Offer
Documents if and to the extent that any such information shall have become false
or misleading in any material respect and Parent and Acquisition each further
agrees to take all steps necessary to cause the Offer Documents as so corrected
to be filed with the SEC and to be disseminated to holders of Shares, in each
case as and to the extent required by applicable federal securities laws.  The
Company and its counsel shall be given a reasonable opportunity to review and
comment on the Offer Documents prior to their filing with the SEC and shall be
provided with any comments Parent, Acquisition and their counsel may receive
from the SEC or its staff with respect to the Offer Documents promptly after
receipt of such comments.

     SECTION 1.2  Company Action.

     (a)  Board Approval.  The Company hereby approves of and consents to the
Offer and represents and warrants that the Board, at a meeting duly called and
held on January 5, 1997, unanimously (i) determined that this Agreement and the
transactions contemplated hereby, including the Offer and the Merger, are fair
to and in the best interests of the stockholders of the Company, (ii) approved
this Agreement and the transactions contemplated hereby, including the Offer and
the Merger and (iii) resolved to recommend that the stockholders of the Company
accept the Offer, tender their Shares thereunder to Acquisition and, if required
by applicable law, approve and adopt this Agreement and the Merger.  The Company
further represents and warrants that Smith Barney Inc. ("Smith Barney") has
delivered to the Board its opinion to the effect that, as of the date of this
Agreement, the Per Share Amount to be received by the holders of Shares (other
than Parent and its affiliates) pursuant to the Offer and the Merger, taken
together, is fair to such holders from a financial point of view.  The Company
has been authorized by Smith Barney to permit the inclusion of such opinion in
its entirety in the Offer Documents and the Schedule 14D-9 referred to below and
the Proxy Statement referred to in Section 3.13, so long as such inclusion is in
form and substance reasonably satisfactory to Smith Barney and its counsel.
Subject to the fiduciary duties of the Board under applicable law (as determined
in good faith after consultation with independent counsel), the Company hereby
consents to the inclusion in the Offer Documents of the recommendations of the
Board described in this Section 1.2(a).

     (b) Schedule 14D-9.  As soon as practicable on the date of commencement of
the Offer, the Company shall file with the SEC a Solicitation/Recommendation
Statement on Schedule 14D-9 (together with any amendments or supplements
thereto, the "Schedule 14D-9") and shall mail the Schedule 14D-9 to the
stockholders of the Company promptly after the commencement of the Offer.  The
Schedule 14D-9 shall, subject to the fiduciary duties of the Board under
applicable law (as determined in good faith after consultation with independent
counsel), at all times contain the determinations, approvals and recommendations
described in Section 1.2(a). Parent, Acquisition and the Company each agrees
promptly to correct any information provided by it for use in the Schedule 14D-9

misleading in any material respect and the Company further agrees to take all
steps necessary to cause the Schedule 14D-9 as so corrected to be filed with the
SEC and to be disseminated to holders of Shares, in each case as and to the
extent required by applicable federal securities laws.  Parent, Acquisition and
their counsel shall be given a reasonable opportunity to review and comment on
the Schedule 14D-9 prior to its filing with the SEC and shall be provided with

with respect to the Schedule 14D-9 promptly after receipt of such comments.

     (c) Dissemination of the Offer.  In connection with the Offer, the Company

furnish Acquisition with such additional information and assistance (including,
without limitation, updated lists of stockholders, mailing labels and lists of
securities positions) as Acquisition or its agents may reasonably request in
communicating the Offer to the record and beneficial holders of Shares.  Subject
to the requirements of applicable law, and except for such steps as are
necessary to disseminate the Offer Documents and any other documents necessary
to consummate the Merger, Acquisition and its affiliates and associates shall
hold in confidence the information contained in any such labels, listings and
files, will use such information only in connection with the Offer and the
Merger, and, if this Agreement shall be terminated, will deliver to the Company
all copies of such information then in their possession.


     SECTION 1.3  Boards of Directors and Committees; Section 14(f).

     (a) Board Representation.  Promptly upon the purchase by Acquisition of
Shares pursuant to the Offer and from time to time thereafter, Acquisition shall
be entitled to designate up to such number of directors, rounded up to the next
whole number, on the Board that equals the product of (i) the total number of
directors on the Board (giving effect to the election of any additional
directors pursuant to this Section) and (ii) the percentage that the number of
Shares owned by Acquisition and its affiliates (including any Shares purchased
pursuant to the Offer) bears to the total number of outstanding Shares, and the
Company shall, upon request by Acquisition, subject to the provisions of Section
1.3(b), promptly either

                                      -4-

Laws to permit such an increase) or use its reasonable best efforts to secure
the resignation of such number of directors as is necessary to enable
Acquisition's designees to be elected to the Board and shall cause Acquisition's
designees to be so elected.  Promptly upon request by Acquisition, the Company
will, subject to the provisions of Section 1.3(b), use its reasonable best
efforts to cause persons designated by Acquisition to constitute the same
percentage as the number of Acquisition's designees to the Board bears to the
total number of directors on the Board on (i) each committee of the Board, (ii)
each board of directors or similar governing body or bodies of each subsidiary
of the Company designated by Acquisition and (iii) each committee of each such
board or body.

     (b) Compliance with Section 14(f).  The Company's obligations to appoint
designees to the Board shall be subject to Section 14(f) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), and Rule 14f-1
promulgated thereunder.  The Company shall promptly take all actions required
pursuant to Section 14(f) and Rule 14f-1 in order to fulfill its obligations
under this Section 1.3 and shall include in the Schedule 14D-9 or a separate
Rule 14f-1 Statement provided to shareholders such information with respect to
the Company and its officers and directors as is required under Section 14(f)
and Rule 14f-1.  Parent or Acquisition will supply to the Company in writing and
be solely responsible for any information with respect to either of them and
their nominees, officers, directors and affiliates required by Section 14(f) and
Rule 14f-1.

     (c) Action by Disinterested Directors.  Following the election or
appointment of Acquisition's designees pursuant to this Section 1.3 and prior to
the Effective Time (as defined below), any amendment of this Agreement or any
amendment to the Restated Certificate of Incorporation or By-Laws of the Company
inconsistent with this Agreement, any termination of this Agreement by the
Company, any extension by the Company of the time for the performance of any of
the obligations or other acts of Parent or Acquisition or any waiver of any of
the Company's rights hereunder will require the concurrence of a majority of the
directors of the Company then in office who are not designees of Acquisition or
employees of the Company.

     SECTION 2.6   Effect on Capital Stock.  At the Effective Time, by virtue of
the Merger and without any action on the part of the Parent, Acquisition, the

     (c)  Stock Options and Employee Stock Purchase Plan.

            (i)   On the date Acquisition purchases Shares pursuant to the

the 1996 Stock Incentive Plan of STAT Healthcare, Inc. (the "Company Stock
Option Plans") or pursuant to any other employee stock option plan or agreement
entered into by the Company with any employee of the Company or any subsidiary
thereof listed on Section 3.11(c) of the Company Disclosure Schedule, whether or
not then exercisable, shall become exercisable, and each holder of a Stock
Option who executes an agreement to cancel such Stock Option shall be entitled
to receive as soon as practicable thereafter from the Company in consideration
for such cancellation an amount in cash (less applicable withholding taxes)
equal to the product of (i) the number of shares of Company Common Stock
previously subject to such Stock Option multiplied by (ii) the excess, if any,
                                        ---------- --
of the Per Share Amount over the exercise price per share of Company Common
Stock previously subject to such Stock Option.

            (ii)  The Board of Directors of the Company, or an appropriate
committee thereof, shall promptly cause written notice of this Agreement to be
given to persons holding options or other rights to purchase Company Common
Stock ("Purchase Rights") under the Company's 1992 Employee Stock Purchase Plan
(the "Company

                                      -7-
<PAGE>

Stock Purchase Plan").  On the date that Acquisition purchases Shares pursuant
to the Offer, all Purchase Rights shall be accelerated and shall be exercised
automatically for shares of Company Common Stock as if the date of this
Agreement were the end of an Option Period (as defined in the Company Stock
Purchase Plan) unless a Participant (as defined in the Company Stock Purchase
Plan) withdraws from the Company Stock Purchase Plan.  Payroll deductions under
the Company Stock Purchase Plan not used to purchase shares of Company Common
Stock shall be returned to the Participant.

     (d)   Capital Stock of Acquisition.  Each share of common stock, $.01 par
value, of Acquisition issued and outstanding immediately prior to the Effective
Time shall be converted into and exchanged for one validly issued, fully paid
and nonassessable share of common stock, $.01 par value, of the Surviving
Corporation.

     SECTION 2.7   Exchange of Certificates.

     (a)  Exchange Agent and Procedures.  Prior to the Effective Time, a bank or
trust company shall be designated by Parent (the "Paying Agent") to act as agent
in connection with the Merger to receive the funds to which holders of Shares
shall become entitled pursuant to Section 2.6(a). Promptly after the Effective
Time, the Surviving Corporation shall cause to be mailed to each record holder,
as of the Effective Time, of a certificate or certificates (the"Certificates")
that, prior to the Effective Time, represented Shares, a form of letter of
transmittal and instructions for use in effecting the surrender of the
Certificates for payment of the Merger Consideration therefor.  Upon the
surrender of each such Certificate formerly representing Shares, together with
such letter of transmittal, duly completed and validly executed in accordance
with the instructions thereto, the Paying Agent shall pay the holder of such
Certificate the Merger Consideration multiplied by the number of Shares formerly
represented by such Certificate, in exchange therefor, and such Certificate
shall forthwith be canceled.  Until so surrendered and exchanged, each such
Certificate (other than Shares held by Parent, Acquisition or the Company, or
any direct or indirect subsidiary thereof) shall represent solely the right to
receive the Merger Consideration.  No interest shall be paid or accrue on the
Merger Consideration.  If the Merger Consideration (or any portion thereof) is
to be delivered to any person other than the person in whose name the
Certificate formerly representing Shares surrendered in exchange therefor is
registered, it shall be a condition to such exchange that the Certificate so
surrendered shall be properly endorsed or otherwise be in proper form for
transfer and that the person requesting such exchange shall pay to the Paying
Agent any transfer or other taxes required by reason of the payment of the
Merger Consideration to a person other than the registered holder of the
Certificate surrendered, or shall establish to the satisfaction of the Paying
Agent that such tax has been paid or is not applicable.

     (b)   Consideration.   When and as needed, Parent or Acquisition shall
deposit, or cause to be deposited, in trust with the Paying Agent the Merger
Consideration to which holders of Shares shall be entitled at the Effective Time
pursuant to Section 2.6(a) hereof.

                                       8
<PAGE>

     (c)   Investment of Merger Consideration. The Merger Consideration shall be
invested by the Paying Agent, as directed by Parent, provided such investments
shall be limited to direct obligations of the United States of America,
obligations for which the full faith and credit of the United States of America
is pledged to provide for the payment of principal and interest, commercial
paper rated of the highest quality by Moody's Investors Service, Inc. or
Standard & Poor's Corporation, or certificates of deposit issued by a commercial
bank having at least $1,000,000,000 in assets.

     (d)   Termination of Duties.  Promptly following the date which is six
months after the Effective Time, Parent will cause the Paying Agent to deliver
to the Surviving Corporation all cash and documents in its possession relating
to the transactions described in this Agreement, and the Paying Agent's duties
shall terminate.  Thereafter, each holder of a Certificate formerly representing
a Share may surrender such Certificate to the Surviving Corporation and (subject
to applicable abandoned property, escheat and similar laws) receive in exchange
therefor the Merger Consideration, without any interest thereon.

     (e)   No Liability.  Neither Parent, Acquisition nor the Company shall be
liable to any holder of Company Common Stock for any Merger Consideration
delivered to a public official pursuant to any applicable abandoned property,
escheat or similar law.

     (f)   Withholding Rights.  Parent or the Exchange Agent shall be entitled
to deduct and withhold from the Merger Consideration otherwise payable pursuant
to this Agreement to any holder of Company Common Stock such amounts as Parent
or the Exchange Agent is required to deduct and withhold with respect to the
making of such payment under the Internal Revenue Code of 1986, as amended (the
"Code"), or any provision of state, local or foreign tax law. To the extent that
amounts are so withheld by Parent or the Exchange Agent, such withheld amounts
shall be treated for all purposes of this Agreement as having been paid to the
holder of the Shares in respect of which such deduction and withholding was made
by Parent or the Exchange Agent.

     SECTION 2.8   Stock Transfer Books.  At the Effective Time, the stock
transfer books of the Company shall be closed, and there shall be no further
registration of transfers of the Company Common Stock thereafter on the records
of the Company.

     SECTION 2.9   No Further Ownership Rights in Company Common Stock.  The
Merger Consideration delivered upon the surrender for exchange of Shares in
accordance with the terms hereof shall be deemed to have been issued in full
satisfaction of all rights pertaining to such Shares, and there shall be no
further registration of transfers on the records of the Surviving Corporation of
Shares which were outstanding immediately prior to the Effective Time.  If,
after the Effective Time, Certificates are presented to the Surviving
Corporation for any reason, they shall be canceled and exchanged as provided in
this Article II.

                                       9
<PAGE>

     SECTION 2.10   Lost, Stolen or Destroyed Certificates.  In the event any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall
deliver in exchange for such lost, stolen or destroyed Certificates, upon the
making of an affidavit of that fact by the holder thereof, the Merger
Consideration such Parent Shares as may be required pursuant to Section 2.6;
provided, however, that Parent may, in its discretion and as a condition
precedent to the issuance thereof, require the owner of such lost, stolen or
destroyed Certificates to deliver a bond in such sum as it may reasonably direct
as indemnity against any claim that may be made against Parent or the Exchange
Agent with respect to the Certificates alleged to have been lost, stolen or
destroyed.

     SECTION 2.11   Taking of Necessary Action; Further Action.  Each of Parent,
Acquisition and the Company will take all such reasonable and lawful action as
may be necessary or appropriate in order to effectuate the Merger in accordance
with this Agreement as promptly as possible.  If, at any time after the
Effective Time, any such further action is necessary or desirable to carry out
the purposes of this Agreement and to vest the Surviving Corporation with full
right, title and possession to all assets, property, rights, privileges, powers
and franchises of the Company and Acquisition, the officers and directors of the
Company and Acquisition immediately prior to the Effective Time are fully
authorized in the name of their respective corporations or otherwise to take,
and will take, all such lawful and necessary action.

     SECTION 2.12   Stockholders' Meeting.  If approval by the Company's
stockholders is required by applicable law to consummate the Merger, the
Company, acting through the Board, shall in accordance with applicable law and
subject to the fiduciary duties of the Board under applicable law (as determined
in good faith after consultation with independent counsel), as soon as
practicable following the consummation of the Offer:

     (i)  duly call, give notice of, convene and hold an annual or special
     meeting of its stockholders (the "Stockholders' Meeting") for the purpose
     of considering and taking action upon this Agreement;

     (ii)  include in the Proxy Statement (as defined in Section 3.13) the
     recommendation of the Board that stockholders of the Company vote in favor
     of the approval and adoption of this Agreement and the transactions
     contemplated hereby; and

     (iii)  use its reasonable best efforts (A) to obtain and furnish the
     information required to be included by it in the Proxy Statement and, after
     consultation with Parent, respond promptly to any comments made by the SEC
     with respect to the Proxy Statement and any preliminary version thereof and
     cause the Proxy Statement to be mailed to its stockholders at the earliest
     practicable time following the consummation of the Offer and (B) to obtain
     the necessary

                                       10
<PAGE>

     approvals by its stockholders of this Agreement and the transactions
     contemplated hereby.

At such meeting, Parent and Acquisition will vote all Shares owned by them in
favor of this Agreement and the transactions contemplated hereby.

     SECTION 2.13   Material Adverse Effect.  When used in connection with the
Company or any of its subsidiaries, or Parent or any of its subsidiaries, as the
case may be, the term "Material Adverse Effect" means any change, effect or
circumstance that is materially adverse to the business, assets, financial
condition or results of operations of the Company and its subsidiaries, or
Parent and its subsidiaries, as the case may be, in each case taken as a whole,
other than any such changes, effects or circumstances:  (i) set forth or
contemplated by the Company Disclosure Schedule or the Parent Disclosure
Schedule, as the case may be; (ii) set forth or described in the Company SEC
Reports or the Parent SEC Reports, as the case may be; or (iii) affecting the
ambulance service industry generally.

<PAGE>

Effective Time, contain any untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary in order to make
the statements therein, in light of the circumstances under which they are made,
not misleading.  Notwithstanding the foregoing, the Company makes no
representation or warranty with respect to any information provided by Parent,
Acquisition and/or by their auditors, legal counsel, financial advisors or other
consultants or advisors specifically for use in the Schedule 14D-9 or the Proxy

regulations thereunder.

     SECTION 3.14   Restrictions on Business Activities.  Except for this
Agreement or as set forth in Section 3.14 of the Company Disclosure Schedule, to
the best of the Company's knowledge, there is no material agreement, judgment,
injunction, order or decree binding upon the Company or any of its subsidiaries
which has or could reasonably be expected to have the effect of prohibiting or
impairing any material business practice of the Company or any of its
subsidiaries, any acquisition of property by the Company or any of its
subsidiaries or the conduct of business by the Company or any of its
subsidiaries as currently conducted or as proposed to be conducted by the
Company, except for any prohibition or impairment as would not have a Material
Adverse Effect.

     SECTION 3.15   Title to Property.  Except as set forth in Section 3.15 of
the Company Disclosure Schedule, the Company and each of its subsidiaries have
good and defensible title to all of their properties and assets, free and clear
of all liens, charges and encumbrances, except liens for taxes not yet due and
payable and such liens or other imperfections of title, if any, as do not
materially detract from the value of or interfere with the present use of the
property affected thereby or which would not have a Material Adverse Effect;
and, to the best knowledge of the Company, all leases pursuant to which the
Company or any of its subsidiaries lease from others material amounts of real or
personal property are in good standing, valid and effective in accordance with
their respective terms, and there is not, to the knowledge of the Company, under
any of such leases, any existing material default or event of default (or event
which with notice or lapse of time, or both, would constitute a material
default), except where the lack of such good standing, validity and
effectiveness or the existence of such default or event of default would not
have a Material Adverse Effect.

     SECTION 3.16   Taxes.

     (a)  For purposes of this Agreement, "Tax" or "Taxes" shall mean taxes,
fees, levies, duties, tariffs, imposts, and governmental impositions or charges
of any kind in the nature of (or similar to) taxes, payable to any federal,
state, local or foreign taxing authority, including (without limitation) (i)
income, franchise, profits, gross receipts, ad valorem, net worth, value added,
sales, use, service, real or personal property, special assessments, capital
stock, license, payroll, withholding, employment, social security, workers'
compensation, unemployment compensation, utility, severance, production, excise,
stamp, occupation,

                                      -19-
<PAGE>

premiums, windfall profits, transfer and gains taxes, and (ii) interest,
penalties, additional taxes and additions to tax imposed with respect thereto;
and "Tax Returns" shall mean returns, reports, and information statements with
respect to Taxes required to be filed with the IRS or any other taxing
authority, domestic or foreign, including, without limitation, consolidated,
combined and unitary tax returns.

     (b)   Other than as disclosed in Section 3.16(b) of the Company Disclosure
Schedule, the Company and its subsidiaries (for such periods as each subsidiary
was owned, directly or indirectly, by the Company) have filed all United States
federal income Tax Returns and all other material Tax Returns required to be
filed by them, and the Company and its subsidiaries have paid and discharged all
Taxes due in connection with or with respect to the periods or transactions
covered by such Tax Returns and have paid all other Taxes as are due, except
such as are being contested in good faith by appropriate proceedings (to the
extent that any such proceedings are required) and except as may be determined
to be owed upon completion of any Tax Return not yet filed based upon an
extension of time to file, and there are no other Taxes that would be due if
asserted by a taxing authority, except with respect to which the Company is
maintaining reserves to the extent currently required except to the extent the
failure to do so would not have a Material Adverse Effect.  Except as does not
involve or would not result in liability to the Company or any of its
subsidiaries that would have a Material Adverse Effect, (i) there are no tax
liens on any assets of the Company or any subsidiary thereof; and (ii) neither
the Company nor any of its subsidiaries has granted any waiver of any statute of
limitations with respect to, or any extension of a period for the assessment of,
any Tax.  The accruals and reserves for Taxes (including deferred taxes)
reflected in the 1996 Company Balance Sheet are in all material respects
adequate to cover all Taxes required to be accrued through the date thereof
(including interest and penalties, if any, thereon and Taxes being contested) in
accordance with generally accepted accounting principles.

     (c)   Neither the Company nor any of its subsidiaries is, or has been, a
United States real property holding corporation (as defined in Section 897(c)(2)
of the Code) during the applicable period specified in Section 897(c)(1)(A)(ii)
of the Code.  To the best knowledge of the Company, neither the Company nor any
of its subsidiaries owns any property of a character, the indirect transfer of
which, pursuant to this Agreement, would give rise to any material documentary,
stamp or other transfer tax.

     SECTION 3.17   Environmental Matters.  Except as set forth in Section 3.17
of the Company Disclosure Schedule, and except in all cases as, in the
aggregate, have not had and would not have a Material Adverse Effect, the
Company and each of its subsidiaries to the best of the Company's knowledge (i)
have obtained all applicable permits, licenses and other authorizations which

any regulation, code, plan, order, decree, judgment, notice or demand letter
issued, entered, promulgated or approved thereunder relating to pollution or
protection of the environment, including laws relating to emissions, discharges,
releases or threatened releases

                                      -20-

(or their respective agents); (ii) are in compliance with all terms and
conditions of such required permits, licenses and authorizations, and also are

have received notice of any past or present violations of Environmental Laws or
any event, condition, circumstance, activity, practice, incident, action or plan
which is reasonably likely to interfere with or prevent continued compliance
with or which would give rise to any common law or statutory liability, or
otherwise form the basis of any claim, action, suit or proceeding, against the
Company or any of its subsidiaries based on or resulting from the manufacture,
processing, distribution, use, treatment, storage, disposal, transport or
handling, or the emission, discharge or release into the environment, of any
pollutant, contaminant or hazardous or toxic material or waste; and (iv) have
taken all actions necessary under applicable Environmental Laws to register any
products or materials required to be registered by the Company or its
subsidiaries (or any of their respective agents) thereunder.

to which the Company is authorized to use any third-party patents, trademarks,
service marks and copyrights ("Third-Party Intellectual Property Rights").  No

of any use, reproduction or distribution of such Third Party Intellectual
Property Rights by or through the Company or any of its subsidiaries, are
currently pending or, to the knowledge of the Company, are overtly threatened by
any person.  The Company does not know of any

                                      -21-
<PAGE>

valid grounds for any bona fide claims (i) to the effect that the manufacture,

     SECTION 6.4   Indemnification and Insurance.

     (a)  The Certificate of Incorporation and By-Laws of the Surviving
Corporation shall contain the provisions with respect to indemnification and
exculpation set forth in the Certificate of Incorporation and By-Laws of the
Company, which provisions shall not be amended, repealed or otherwise modified
for a period of three years from the Effective Time in any manner that would
adversely affect the rights thereunder of individuals who at the Effective Time
were directors, officers, employees or agents of the Company, unless such
modification is required by law.

     (b)   The Company shall, to the fullest extent permitted under applicable
law or under the Company's Certificate of Incorporation or By-Laws and

omissions occurring at or prior to the Effective Time, to the same extent as
provided in the respective Certificate of Incorporation or By-Laws of the
Company or the subsidiaries or any applicable contract or agreement as in effect
on the date hereof, in each case for a period of three years after the date

three-year period, all rights to indemnification in respect of any such claim

                                      -31-

of any two or more Indemnified Parties.  The indemnity agreements of Parent and

or entity who controls, or in the past controlled, any present or former
director, officer or employee of the Company or any of its subsidiaries.

     (c)   The Surviving Corporation shall honor and fulfill in all respects the
obligations of the Company pursuant to indemnification agreements with the

and officers' liability insurance covering those persons who are currently
covered by the Company's directors' and officers' liability insurance policy (a
copy of which has been made available to Parent) on terms (including the amounts
of coverage and the amounts of deductibles, if any) that are comparable to the
terms now applicable to directors and officers of Parent, or, if more favorable
to the Company's directors and officers, the terms now applicable to them under
the Company's current policies; provided, however, that in no event shall Parent
or the Surviving Corporation be required to expend in excess of 300% of the
annual premium currently paid by the Company for such coverage; and provided
further, that if the premium for such coverage exceeds such amount, Parent or
the Surviving Corporation shall purchase a policy with the greatest coverage
available for such 300% of the annual premium.

     (e)  From and after the Effective Time, Parent shall guarantee the
obligations of the Surviving Corporation under this Section 6.4.

Effective Time, is intended to benefit the Company, the Surviving Corporation
and the Indemnified Parties, shall be binding on all successors and assigns of
the Surviving Corporation and shall be enforceable by the Indemnified Parties.

assigns (i) consolidates or merges into any other person or entity and shall not
be the continuing or surviving corporation or entity in such consolidation or
merger or (ii) transfers all or substantially all of its properties and assets
to any person or entity, then and in such case, proper provisions shall be made

the case may be) assume the obligations of Parent and the Surviving Corporation
set forth in this Section.

<PAGE>

cause any representation or warranty contained in this Agreement to be
materially untrue or inaccurate, or (ii) any failure of the Company, Parent or
Acquisition, as the case may be, materially to comply with or satisfy any
covenant, condition or agreement to be complied with or satisfied by it
hereunder; provided, however, that the delivery of any notice pursuant to this
Section shall not limit or otherwise affect the remedies available hereunder to
the party receiving such notice.

     SECTION 6.6  Further Action.  Upon the terms and subject to the conditions
hereof, each of the parties hereto shall use all reasonable efforts to take, or
cause to be taken, all actions, and to do, or cause to be done, all other things
necessary, proper or advisable to consummate and make effective as promptly as
practicable the transactions contemplated by this Agreement, to obtain in a
timely manner all necessary waivers, consents and approvals and to effect all
necessary registrations and filings, and otherwise to satisfy or cause to be
satisfied all conditions precedent to its obligations under this Agreement.  The

Parent or the Company except such actions that would not have a Material Adverse
Effect on Parent and its subsidiaries taken as a whole.

with each other before issuing any press release with respect to the Merger or
this Agreement and shall not issue any such press release or make any such
public statement without the prior consent of the other party, which shall not
be unreasonably withheld; provided, however, that a party may, without the prior
consent of the other party, issue such press release or make such public
statement as may upon the advice of counsel be required by law or the rules and
regulations of the New York Stock Exchange, Inc. ("NYSE"), if it has used all
reasonable efforts to consult with the other party.

     SECTION 6.8   Conveyance Taxes.  Parent and the Company shall cooperate in
the preparation, execution and filing of all returns, questionnaires,
applications, or other documents regarding any real property transfer or gains,
sales, use, transfer, value added, stock transfer and stamp taxes, any transfer,
recording, registration and other fees, and any similar taxes which become
payable in connection with the transactions contemplated hereby that are
required or permitted to be filed on or before the Effective Time.

stockholders of the Company or Parent:

     (a)   by mutual written consent duly authorized by the Boards of Directors

nonappealable final order, decree or ruling or taken any other action having the
effect of permanently restraining, enjoining or otherwise prohibiting the Merger
(provided that the right to terminate this Agreement under this Section 8.1(b)
shall not be available to any party who has not complied with its obligations
under Section 6.6 and such noncompliance materially contributed to the issuance
of any such order, decree or ruling or the taking of such action); or

     (c)  by either Parent or the Company if Acquisition shall have (A)
terminated the Offer or (B) failed to accept for purchase and pay for Shares
pursuant to the Offer by April 15, 1997 unless Acquisition's actions are a
result of the receipt by the Company of an Acquisition Proposal or a request for
additional information under the HSR Act or the failure to obtain any necessary
governmental or regulatory approval, in which case if Acquisition shall have
failed to accept for purchase and pay for Shares by July 15, 1997 (provided that
the right to terminate this Agreement under this Section 8.1(c) shall not be
available to any party whose failure to fulfill any obligation under this
Agreement has been the cause of or resulted in any of the circumstances
described in clauses (A) and (B) before such date); or

     (d)   by Parent or the Company, prior to the purchase of Shares pursuant to
the Offer, if the Board of Directors of the Company shall withdraw, modify or
change its approval or recommendation of the Offer, this Agreement or the Merger
in a manner adverse to Parent; or

     (e)   by Parent or the Company, prior to the purchase of Shares pursuant to
the Offer, (i) if any representation or warranty of the Company or Parent,
respectively, set forth in this Agreement shall be untrue when made, or (ii)
upon a breach in any material respect of any covenant or agreement on the part
of the Company or Parent, respectively, set forth in this Agreement, in each
case where such untruth or breach would have a Material Adverse Effect on the
Company or the Parent, as the case may be (either (i) or (ii) above being a
"Terminating Breach"), provided, that, if such Terminating Breach is curable by
the Company or Parent, as the case may be, through the exercise of its
reasonable best efforts and for so long as the Company or Parent, as the case
may be, continues to exercise such reasonable best efforts, neither Parent nor
the Company, respectively, may terminate this Agreement under this Section
7.1(e).

     SECTION 8.2   Effect of Termination.  In the event of the termination of
this Agreement pursuant to Section 8.1, this Agreement shall forthwith become
void and there shall be no liability on the part of any party hereto or any of
its affiliates, directors, officers or stockholders except (i) as set forth in
Section 8.3 and Section 9.1 hereof, and (ii) except as otherwise provided in
Section 8.3, nothing herein shall relieve any party from liability for any
Termination Breach hereof by such party.

Fee"), upon the first to occur of the following events:

           (i)  the termination of this Agreement by Parent pursuant to Section
8.1(d); or

          (ii)  the termination of this Agreement by Parent pursuant to Section
8.1(e) on account of a Terminating Breach by the Company.

     (c)  The Company Fee payable pursuant to Section 8.3(b) shall be paid
within two (2) business days after the first to occur of any of the events
described in Section 8.3(b)(i) or (ii); provided, that, in no event shall the
Company be required to pay such Fee to Parent if, immediately prior to the
termination of this Agreement, Parent was in breach of any of its material
obligations under this Agreement.  The payment of Company Fee shall be Parent's
sole and exclusive remedy for the event giving rise to the payment of the
Company Fee.

                                                            ANNEX A


                                OFFER CONDITIONS

          The capitalized terms used in this Annex A have the meanings set forth
in the attached Agreement, except that the term "Merger Agreement" shall be
deemed to refer to the attached Agreement and the term "Commission" shall be
deemed to refer to the SEC.

          Notwithstanding any other provision of the Offer, Acquisition shall
not be required to accept for payment or, subject to any applicable rules and
regulations of the Commission, including without limitation, Rule 14e-1(c) under
the Exchange Act (relating to Acquisition's obligation to pay for or return
Shares promptly after termination or withdrawal of the Offer), pay for any
Shares tendered pursuant to the Offer, and may postpone the acceptance for
payment or, subject to the restriction referred to above, payment for any Shares
tendered pursuant to the Offer, and may terminate or amend the Offer and not
accept for payment any Shares, if (i) the Minimum Condition shall not have been
satisfied, or (ii) any applicable waiting period under the HSR Act shall not
have expired or been terminated; provided, that prior to April 15, 1997, (or, if
the conditions to the Offer have not been satisfied prior to April 15, 1997 as
the result of the receipt by the Company of an Acquisition Proposal or as a
result of a failure of the applicable waiting period under the HSR Act to expire
or the failure to obtain any necessary governmental or regulatory approvals,
prior to July 15, 1997) Acquisition shall not terminate the Offer by reason of
the nonsatisfaction of any of the conditions and shall extend the Offer, or
(iii) Acquisition shall not have been reasonably satisfied that the provisions
of Section 203 of the Delaware General Corporation Law are inapplicable to the
Offer and Merger, or (iv) at any time on or after five days after announcement
and prior to the acceptance for payment of Shares, any of the following
conditions occurs:

          (a) there shall have been any action or proceeding brought by any
governmental authority before any court located or having jurisdiction within
the United States or Canada or any statute, regulation, legislation, judgment or
order, enacted, entered, enforced, promulgated, amended, issued or deemed
applicable to the Offer or the Merger by any court, governmental, administrative
or regulatory authority or agency located or having jurisdiction within the
United States or Canada that could result in a Material Adverse Effect and have
the effect of:  (i) making illegal, or otherwise directly or indirectly
restraining or prohibiting or imposing material penalties or fines or requiring
the payment of material damages in connection with the making of, the Offer, the
acceptance for payment of, payment for, or ownership, directly or indirectly, of
some of or all the Shares by Parent or Acquisition, the consummation of the
Offer or the Merger; (ii) prohibiting or materially limiting the direct or
indirect ownership or operation by the Company or by Parent of all or any
material portion of the business or assets of the Company and its subsidiaries,
taken as a whole, or compelling Parent to dispose of or hold separate all or any
material portion of the business or assets of the
<PAGE>

Company and its subsidiaries, taken as a whole, as a result of the transactions
contemplated by the Merger Agreement; (iii) imposing or confirming material
limitations on the ability of Parent effectively to hold or to exercise full
rights of ownership of Shares, including, without limitation, the right to vote
any Shares on all matters properly presented to the stockholders of the Company;
or (iv) requiring divestiture by Parent or Acquisition, directly or indirectly,
of any Shares; or

          (b) the Company shall have breached or failed to perform in any
material respect any of its covenants or agreements under the Merger Agreement
or any of the representations and warranties of the Company set forth in the
Merger Agreement shall not be true and correct both when made and as of the date
of consummation of the Offer (except to the extent such representations and
warranties of the Company address matters only as of a particular date, in which
case as of such date) except where the failure to perform such covenants or
agreements or the failure of such representation and warranties to be so true
and correct would not have a Material Adverse Effect; or

          (c) The Merger Agreement shall have been terminated in accordance with
its terms or the Offer shall have been amended or terminated with the consent of
the Company;

which, in the reasonable judgment of Acquisition in any such case, and
regardless of the circumstances (including any action or omission by Acquisition
not inconsistent with the Merger Agreement) giving rise to any such condition,
makes it inadvisable to proceed with such acceptance for payment or payments of
Shares.

          The foregoing conditions are for the sole benefit of Acquisition 
and may be asserted by Acquisition regardless of the circumstances giving 
rise to any such condition or may be waived by Acquisition in whole or in 
part at any time or from time to time in its sole discretion. The failure by 
Acquisition at any time to exercise any of the foregoing rights shall not be 
deemed a waiver of any such right, the waiver of any such right with respect 
to particular facts or circumstances shall not be deemed a waiver with 
respect to any other facts or circumstances, and each such right shall be 
deemed an ongoing right that may be asserted at any time or from time to time.

Each agreement has an initial term of three years, with automatic extensions of
one year added annually unless terminated, and with a covenant-not-to-compete
with the Company for a period of two years following termination of employment.
Each agreement requires the executive to devote his full time, attention and
efforts to the business and affairs of the Company.  If the Company terminates
Mr. Shirley's employment agreement other than for cause, Mr. Shirley will be
entitled to a termination payment approximately equal to two times his base
salary, plus two times the greater of (i) any bonus or incentive compensation
paid to him during the previous twelve months or (ii) 50% of his base salary.
In addition, all options to purchase Common Stock which were previously granted
to Mr. Shirley shall immediately vest.  If the Company terminates Mr. DeHuff's
employment agreement other than for cause, Mr. DeHuff will be entitled to a
termination payment approximately equal to 1.5 times his base salary, plus 1.5
times the greater of (i) any bonus or incentive compensation paid to him during
the previous twelve months or (ii) 50% of his base salary.  In addition, all
options to purchase Common Stock which were previously granted to Mr. DeHuff
shall immediately vest.  Base salaries for 1996 are: Mr. Shirley -- $300,000 and
Mr. DeHuff -- $250,000.

CHANGE-IN-CONTROL ARRANGEMENTS

     The Company maintains an Executive Separation Allowance Plan (the
"Separation Plan") under which a participating executive is entitled to certain
benefits if, within 90 days following a change in control of the Company, the
executive is terminated other than for cause or if the executive terminates his
employment for good reason.  Good reason includes a major reduction in the
executive's responsibilities, a significant reduction in base

<PAGE>

salary or total benefits or a relocation outside of 50 miles from the
executive's principal location of employment.  The terminated executive is
entitled to a cash payment equal to a designated multiple of the sum of his
highest annual base salary during the last five years and the highest annual
bonus during the last three years.  In addition, the executive will receive one
year's life insurance coverage in an amount equal to two times his highest
annual base salary during the previous five years and medical and dental
coverage for one year.  All stock options held by the executive will also become
exercisable.  Messrs. Shirley and DeHuff participate in the Separation Plan and
their designated salary and bonus multiples are 2.99 and 2.00, respectively.

SEVERANCE AND CONSULTING ARRANGEMENTS

     Beginning in 1996, Mr. Verrochi ceased being a full-time employee of the
Company.  In connection with his change in status and the cancellation of his
then existing employment contract, Mr. Verrochi executed a severance agreement
and the Company agreed to make a lump sum payment to him of $952,000 and to
accelerate the exercisability of stock options covering 96,000 shares of Common
Stock held by Mr. Verrochi.  Mr. Verrochi has agreed not to compete with the
Company for a period of two years.

     Beginning in April 1996, Mr. Puopolo ceased being a full-time employee of
the Company.  In connection with his change in status and the cancellation of
his then existing employment contract, Mr. Puopolo executed a severance
agreement and the Company agreed to make a lump sum payment to him of $802,000
and to accelerate the exercisability of stock options covering 92,000 shares of
Common Stock held by Mr. Puopolo.  Mr. Puopolo has agreed not to compete with
the Company for a period of two years.   Mr. Puopolo remains as member of the
Board of Directors.

     The Company has also entered into consulting agreements with Exel Holdings
Ltd., a company owned by Messrs. Verrochi and Puopolo, to provide consulting
services in connection with the Company's acquisition program.  Payments under
the consulting agreements, each of which has a term of one year, in the
aggregate are $20,000 per acquisition up to a maximum of $200,000.

     In connection with Mr. Paolella's termination of active employment with the
Company, the Company entered into a severance arrangement with him under which
the Company agreed to make to him a lump sum payment of $252,700 and to
accelerate the exercisability of stock options covering 8,000 shares of Common
Stock that Mr. Paolella holds.  Mr. Paolella has agreed not to compete with the
Company for a period of two years.

     Until December 1995 the Company had been paying to James E. McGrath a
monthly consulting retainer of $5,600 in connection with services he performed.
Beginning in 1996 the Company ceased paying the retainer, although Mr. McGrath
will remain available on an hourly basis if requested by the Company.  In
connection with this restructuring of this consulting arrangement the Company
agreed to make a lump sum payment to Mr. McGrath of $134,400.

           COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     Messrs. Thompson, Hammond and Michael A. Baker, none of whom is or was an
executive officer or employee of the Company, served on the Compensation
Committee during 1995.  The Company is a party to a consulting agreement with
DECCS, Inc., a company owned by a trust for the benefit of Mr. Baker's children,
pursuant to which Mr. Baker provides certain merger and acquisition advice as
required by the Company.  Under that Agreement, DECCS is paid monthly at the
rate of $75,000 per year.  During 1995, the Company paid DECCS approximately
$90,000 pursuant to the consulting agreement.

             ITEM 3 - AMENDMENT TO 1992 EMPLOYEE STOCK PURCHASE PLAN

     On February 22, 1996, the Board of Directors approved, subject to
stockholder approval, an amendment (the "Amendment") to the 1992 Employee Stock
Purchase Plan (the "Purchase Plan") to increase the maximum number of shares of
Common Stock available for issuance under the Purchase Plan from 200,000 to
400,000 (subject to adjustment for stock splits and similar changes).  During
1993, 1994 and 1995, employees purchased 44,862, 55,595 and 71,368 shares of
stock under the Purchase Plan.  The Board of Directors believes that the
Purchase Plan provides a convenient way for employees to become stockholders of
the Company and to align their interests more closely with those of the
stockholders.  The Board believes that it is possible that, at the current rate
of employee participation, the number of shares reserved for issuance would be
awarded prior to the time of the next annual meeting of stockholders.
Accordingly, it adopted the Amendment, subject to stockholder approval.

     The Purchase Plan is designed to enable eligible employees to purchase
shares of Common Stock at a discount through payroll deductions.  All employees
who customarily work more than 20 hours per week and who have completed at least
six months of continuous service, other than employees owning 5% or more of the
Common Stock, are eligible to participate.  As of April 1, 1996, there were
approximately 8,800 employees eligible to participate in the Purchase Plan.
Purchases occur twice a year at the end of six-month option periods beginning on
January 1 and July 1.  The purchase price for Common Stock under the Purchase
Plan is 85% of the lesser of the fair market value of the Common Stock at the
beginning of the option period and the fair market value of the Common Stock at
the end of the option period.  Participants may elect under the Purchase Plan to
have between 2% and 10% of their pay withheld and applied to the purchase of
shares at the end of the option period.

     If a participant's employment with the Company terminates, the
participant's option to purchase shares for that period will be deemed canceled
and the balance of the participant's payroll withholding account will be
refunded.  If a participant dies during an option period, the participant's
option will be deemed canceled and the balance of his or her payroll withholding
account refunded unless the participant elected, as part of a valid beneficiary
designation, to have such balance applied at the end of the period toward the
purchase of shares of Common Stock to be delivered to the beneficiary.

     The following discussion of certain federal income tax consequences
associated with participation in the Purchase Plan is based on the law as in
effect on April 1, 1996.  It does not purport to cover federal employment tax or
other federal tax consequences that may be associated with the Purchase Plan,
nor does it cover state, local or non-U.S. taxes.

                          TRANSACTIONS WITH MANAGEMENT

REAL PROPERTY TRANSACTIONS

     The Company leases two ambulance stations in Santa Cruz, California from
Paul T. Shirley.  The aggregate amount of lease payments for these properties
incurred by the Company in 1995 was approximately $59,000.

     The Company leases its administrative facility in New Haven, Connecticut
from P&J Realty, a partnership in which Joseph R. Paolella is a partner.  The
lease and related real estate tax payments paid by the Company to P&J Realty for
this property in 1995 totaled approximately $423,000.  On March 31, 1996, the
Company made a payment to P&J Realty of $527,403 which represented the
discounted present value of future payments under the lease in excess of the
fair market value and the then current version of the lease was canceled.  The
Company has entered into a new lease which provides for annual base rent of
$290,940 during the initial term with an increase to $339,430 seventeen months
after the commencement of any renewal period.  The new lease is for five years
and allows either party to renew for an additional five-year period.

     The Company has leased its administrative facility in Gulfport, Mississippi
from Mr. Rester.  The Company paid $163,000 in lease payments on this property
during 1995.  The lease for this property has a term of five years and expires
in January 1999, with an option for the Company to extend the term for an
additional five-year period.  The lease provides for annual rent of
approximately $131,300.  Mr. Rester has expanded the facility at the Company's
request and rent payments when approved for the new facilities will increase the
annual rent by approximately $40,800 annually to annual rent of approximately
$172,100.

COMPANY POLICY

     The Company adopted a policy in June 1992 whereby any future transaction
with an officer, director or affiliate will be on terms no less favorable to the
Company than could be obtained from unrelated third parties and will be approved
by a majority of the disinterested members of the Company's Board of Directors.

                     RELATIONSHIP WITH INDEPENDENT AUDITORS

     The Board of Directors has selected the firm of KPMG Peat Marwick,
certified public accountants, as auditors for the Company for the fiscal year
ending December 31, 1996.  A representative of KPMG Peat Marwick is expected to
be present at the Meeting with the opportunity to make a statement if he or she
desires and to respond to appropriate questions.

                              STOCKHOLDER PROPOSALS

     Proposals of stockholders intended to be included in the Company's proxy
materials for the Company's 1997 annual meeting of stockholders must be received
by the Company not later than December 10, 1996 at its principal executive
office, 2821 South Parker Road, 10th floor, Aurora, Colorado  80014.

Dear Stockholder:
 
    We are pleased to report that, on January 6, 1997, American Medical
Response, Inc. (the "Company") entered into a merger agreement with Laidlaw Inc.
and one of its subsidiaries that provides for the acquisition of the Company by
Laidlaw at a price of $40.00 per share in cash. Under the terms of the proposed
transaction, a Laidlaw subsidiary is today commencing a cash tender offer for
all outstanding shares of the Company common stock at $40.00 per share.
Following the successful completion of the Laidlaw tender offer, the Laidlaw
subsidiary will be merged into the Company and all shares not purchased in the
Laidlaw tender offer will be converted into the right to receive $40.00 per
share in cash in the merger.
 
    YOUR BOARD OF DIRECTORS HAS APPROVED THE LAIDLAW TENDER OFFER AND DETERMINED
THAT THE TERMS OF THE TENDER OFFER AND THE MERGER, TAKEN TOGETHER, ARE FAIR TO,
AND IN THE BEST INTERESTS OF, THE COMPANY AND ITS STOCKHOLDERS. ACCORDINGLY, THE
BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT ALL COMPANY STOCKHOLDERS ACCEPT
THE LAIDLAW TENDER OFFER AND TENDER THEIR SHARES TO LAIDLAW.
 
    In arriving at its recommendations, the Board of Directors gave careful
consideration to a number of factors. These factors included the opinion dated
January 6, 1997 of Smith Barney Inc., financial advisor to the Company, to the
effect that, as of such date and based upon and subject to certain matters
stated in such opinion, the cash consideration of $40.00 per share to be
received by Company stockholders (other than Laidlaw and its affiliates) in the
offer and the merger, taken together, was fair from a financial point of view to
such stockholders.
 
    Accompanying this letter is a copy of the Company's
Solicitation/Recommendation Statement on Schedule 14D-9. Also enclosed is
Laidlaw's Offer to Purchase and related materials, including a Letter of
Transmittal for use in tendering shares. We urge you to read the enclosed
materials, including Smith Barney's opinion which is attached to the Schedule
14D-9, carefully.
 
    The management and directors of American Medical Response, Inc. thank you
for the support you have given the Company.
 
                                          Sincerely,
 
                                                 [SIGNATURE]
                                          Paul T. Shirley

FOR IMMEDIATE RELEASE

                               LAIDLAW TO ACQUIRE
                         AMERICAN MEDICAL RESPONSE, INC.

             MERGER WILL COMBINE TOP TWO AMBULANCE COMPANIES IN U.S.


JANUARY 6, 1997 -- AURORA, COLORADO -- American Medical Response, Inc.
(NYSE:EMT) announced today that it had signed a definitive agreement through
which Laidlaw Inc. (NYSE:LDWB) will acquire American Medical Response.

According to the terms of the merger agreement, Laidlaw will commence a tender
offer to acquire 100 percent of American Medical Response's outstanding shares
for $40 per share, or an equity value of approximately of $1.12 billion.  The
transaction is expected to close in February, subject to a tender of a minimum
of two-thirds of American Medical Response's outstanding shares, required
regulatory approvals, and other customary conditions.  American Medical Response
currently has approximately 28 million fully diluted common shares outstanding.

Laidlaw plans to merge its San Diego, California-based MedTrans ambulance
services unit with American Medical Response.  The combined entity will operate
as American Medical Response, Inc. and will remain headquartered in Aurora,
Colorado.  Paul T. Shirley, currently Chief Executive Officer of American
Medical Response, will continue in that role.

"This transaction represents a significant realization of value for our
shareholders," said Paul T. Shirley, Chief Executive Officer.  "American Medical
Response and MedTrans are two highly successful medical transportation providers
sharing a common view of the future of emergency medical services.  The
combination will create an organization with even greater operating efficiencies
and improved service for our patients.  As a combined entity, we will be well
positioned to expand the scope of emergency and urgent care services offered to
municipalities and health care payors."

<PAGE>

"We have known and respected the management of MedTrans for the past several
years," Mr. Shirley continued.  "We plan to capitalize on the experience of both
executive teams as we grow the new company."

Since its initial public offering in 1992, American Medical Response has
acquired more than 70 ambulance providers.  MedTrans, acquired by Laidlaw in
mid-1993, has acquired 80 ambulance companies and currently operates in 23
states.  Both companies provide a variety of emergency and non-emergency medical
transportation and related services to municipalities, health care payors, and
individuals.  Upon completion of the merger, approximately 40% of Laidlaw's
total revenue will be derived from medical transportation and related services.

American Medical Response's Board of Directors received a fairness opinion
regarding the merger from Smith Barney.  Merrill Lynch & Co. is acting as the
financial advisor to Laidlaw for the transaction.

American Medical Response is the nation's leading provider of emergency and non-
emergency medical transportation services, with operations in 28 states and over
12,000 employees.  Laidlaw, Inc. is a major provider of transportation and
environmental services to municipalities and industries through the United
States and Canada.

                              EMPLOYMENT AGREEMENT
 
    This Agreement among American Medical Response, Inc., a Delaware corporation
(the "Company") and David C. Colby ("Executive") is hereby entered into as of
April 1, 1996.
 
                                   RECITALS:
 
    As of the date of this Agreement, the Company and its affiliates are engaged
in the business of medical transportation services. The operations of the
Company and its subsidiaries are a complex matter requiring direction and
leadership in a variety of arenas, including financial, strategic planning,
regulatory, community relations and others. The Executive is possessed of
certain experience and expertise that qualify him to provide the direction and
leadership required by the Company and its subsidiaries.
 
    Executive is or will be employed by the Company in a confidential
relationship wherein Executive, in the course of his employment with the
Company, will become familiar with and aware of information as to the specific
manner of doing business and the customers of the Company, and its subsidiaries
and future plans with respect thereto, all of which will be established and
maintained at great expense to the Company and its subsidiaries; this
information is a trade secret and constitutes the valuable goodwill of the
Company and its subsidiaries.
 
    Executive recognizes that the business of the Company and its subsidiaries
depends upon a number of trade secrets, including secret techniques, methods and
data. The protection of these trade secrets is of critical importance to the
Company and its subsidiaries.
 
    The Company and its subsidiaries will sustain great loss and damage if
Executive should violate the provisions of paragraph 3 of this Agreement.
Further, monetary damages for such losses would be extremely difficult to
measure.
 
    NOW, THEREFORE, in consideration of the mutual promises, terms, covenants
and conditions set forth herein and the performance of each, it is hereby agreed
as follows:
 
    1.  EMPLOYMENT AND DUTIES.
 
        (a) The Company hereby employs Executive as Chief Financial Officer and
    Executive Vice President to perform the duties normally associated
    therewith. Executive hereby accepts this employment upon the terms and
    conditions herein contained. Executive shall faithfully adhere to, execute
    and fulfill all policies established by the Company. During the term of his
    employment, as defined in paragraph 6(a), Executive shall devote his full
    time, attention and efforts to promote and further the business and services
    of the Company and perform all services not inconsistent with his position
    which the Company s Board of Directors and Chief Executive Officer shall
    designate, use his best efforts to promote the Company s interests, and
    serve as director of the Company if elected as such.
 
        (b) Executive shall perform such duties, assume such responsibilities
    and devote such time, attention and energy to the business of the Company as
    the Board of Directors and President of the Company shall from time to time
    require and shall have all powers and duties consistent with such positions,
    subject to the direction of the Board.
 
        (c) All funds received by Executive on behalf of the Company, if any,
    shall be held in trust for the Company and shall be delivered to the Company
    as soon as practicable.
 
        (d) The Company agrees to propose to the shareholders of the Company,
    upon the recommendation of the Nominating Committee of the Board of
    Directors, at each appropriate Annual Meeting of such shareholders during
    the term hereof (provided the Executive continues in his position and is not
    in material violation of this Agreement) the election or reelection of the
    Executive as a member of the Board of Directors of the Company, provided
    that the Executive is otherwise eligible for such election.
<PAGE>
    2.  COMPENSATION AND EXPENSES.  For all services rendered by Executive to
the Company, the Company shall compensate the Executive as follows:
 
        (a)  BASE SALARY.  The base salary payable to Executive shall be not
    less than $275,000 per year payable in accordance with the Company's
    customary pay practices.
 
        (b)  ANNUAL BONUS.  Executive shall be eligible for an annual
    performance bonus subject to the evaluation and approval of the Compensation
    Committee of the Board of Directors.
 
        (c)  EXPENSES.  Executive shall be entitled to reimbursement for
    expenses incurred on behalf of the Company in the performance of his duties
    hereunder, consistent with the Company's reimbursement policies.
 
        (d)  DISABILITY.  Executive shall be entitled to receive for a period of
    up to six (6) months his base salary and a pro rata portion of his bonus
    during such time as, because of illness or physical or mental disability or
    other incapacity, he is unable to perform his duties under this Agreement.
    Such amounts payable shall be offset by any amounts paid to Executive under
    disability insurance policies maintained by the Company.
 
        (e)  OTHER BENEFITS.  In addition to the benefits described above,
    Executive shall be entitled, during the term hereof and subject to any
    contribution therefor generally required of executives of the Company, to
    participate in any and all employee benefit plans from time to time in
    effect for employees or executives of the Company generally, except to the
    extent such plans are in a category of benefit otherwise provided to the
    Executive. Such benefits and participation shall be subject to (i) the terms
    of the applicable plan documents, (ii) generally applicable Company policies
    and (iii) the discretion of the Board or any administrative or other
    committee provided for in or contemplated by such plan. The Company may
    alter, modify, add to or eliminate its employee benefit plans at any time as
    it, in its sole judgment, determines to be appropriate, without recourse by
    the Executive.
 
        (f)  CHANGE OF CONTROL.  The parties acknowledge that the Executive is
    subject to the provisions of and entitled to certain benefits under the
    Company s Executive Separation Allowance Plan. The Executive acknowledges
    and agrees that in addition to this Agreement, his inclusion in the Company
    s Executive Separation Allowance Plan constitutes good and valuable
    consideration for his covenants under Paragraph 3 of this Agreement.
 
    3.  NON-COMPETITION AGREEMENT; TRADE SECRETS.
 
        (a) Executive agrees that, during the term of his employment with the
    Company and for a two-year period following termination of his employment
    with the Company for any reason, he shall not, directly or indirectly, for
    himself or on behalf of any other person, company, partnership, corporation
    or business of whatever nature:
 
           (i) knowingly call upon any then current customer of the Company or
       any of its subsidiaries (including any such customer obtained by the
       Executive) for the purpose of soliciting or selling any services or
       products in competition with those of the Company or any of its
       subsidiaries;
 
           (ii) knowingly solicit any employee of the Company or any of its
       subsidiaries for the purpose or with the intent of enticing them away
       from or out of the employ of the Company or any of its subsidiaries for
       any reason whatsoever;
 
           (iii) establish, enter into, be employed by or for, advise, consult
       with or become an owner in or a part of, any company, partnership,
       corporation or other business entity or venture, or in any way engage in
       business where a material portion of such entity or business competes in
       the business of providing medical transportation services with the
       Company or any of its subsidiaries, within the United States of America
       or within 100 miles of any location in which the Company or any of its
       subsidiaries conducts business; or
 
                                       2
<PAGE>
           (iv) call upon any prospective acquisition candidates on Executive's
       own behalf or on behalf of any competitor, which candidate was either
       called upon by the Executive or for which Executive made an acquisition
       analysis for the Company.
 
    Ownership of not more than one percent of the voting stock of a corporation
whose stock is traded on a national securities exchange or over-the-counter
shall not of itself constitute a violation of this paragraph 3(a).
 
        (b) Executive agrees that he will not, during or after the term of his
    employment with the Company, disclose or use for his personal benefit,
    nonpublic confidential information relating to the customers or other trade
    secrets (whether in existence or proposed) of the Company or any of its
    subsidiaries, or any other confidential information of the Company or its
    subsidiaries to any person, firm, partnership, corporation or business for
    any reason or purpose whatsoever.
 
        (c) Because of the difficulty of measuring economic losses to the
    Company and its subsidiaries as a result of the breach of any of the
    foregoing covenants, and because of the immediate and irreparable damage
    that would be caused to the Company and its subsidiaries for which they may
    have no other adequate remedy, Executive agrees that, in the event of a
    breach by him of any of the foregoing covenants, the Company or any of its
    subsidiaries may, in addition to obtaining any other remedy or relief
    available to it, enforce the foregoing covenants by all equitable relief,
    including injunctions and restraining orders.
 
        (d) The covenants in this paragraph 3 are severable and separate, and
    the unenforceability of any specific covenant shall not affect the
    provisions of any other covenant. Moreover, in the event any court of
    competent jurisdiction shall determine that the scope, time or territorial
    restrictions set forth are unreasonable, then it is the intention of the
    parties that such restrictions be enforced to the fullest extent which the
    court deems reasonable, and this Agreement shall thereby be reformed.
 
        (e) It is specifically agreed that the post-termination non-competition
    period referred to in paragraph 3(a) shall be computed by excluding from
    such computation any time during which Executive is in violation of any
    provision of this paragraph 3 as determined by a final and nonappealable
    decree of a court of competent jurisdiction.
 
    4.  RETURN OF COMPANY PROPERTY.  All records, plans, memoranda, lists and
other property delivered to Executive by or on behalf of the Company or any of
its subsidiaries or by a customer of any of them (including but not limited to,
any such customers obtained by Executive), and all records compiled by the
Executive which pertain to the business of the Company or any of its
subsidiaries shall be and remain the property of the Company or such subsidiary,
as the case may be, and be subject at all times to its discretion and control.
Likewise, all correspondence with customers or representatives, reports,
records, charts, advertising materials, and any data collected by Executive, or
by or on behalf of the Company, any of its respective subsidiaries or any
representative of any of them shall be delivered promptly to the Company without
request by them upon termination of Executive's employment.
 
    5.  INVENTIONS.  Executive shall disclose promptly to the Company any and
all conceptions and ideas for inventions, improvements, discoveries and works,

Executive solely or jointly with another during the period of employment which
are related to the business or activities of the Company or any of its
subsidiaries or which Executive conceives as a result of his employment by the
Company (collectively, "Proprietary Rights"), and Executive hereby assigns and
agrees to assign all his interests therein to the Company or its nominee. All
copyrightable Proprietary Rights shall be considered to be "works made for
hire". Whenever requested to do so by the Company, Executive shall execute any
and all applications, assignments or other instruments and do such other acts
that the Company shall request to apply for and obtain Letters Patent of the
United States or any foreign country or to otherwise protect the Company's
interest therein. These obligations

shall continue beyond the termination of employment with respect to inventions,
improvements, discoveries and works, whether or not patentable or copyrightable,
conceived, made or acquired by Executive during the period of employment, and

legal representatives.

    shall not otherwise accelerate the payment date of any monies accrued or
    accruing to the account of Executive as a result of any bonuses or other
    compensation, nor shall termination vest in Executive any right in
    connection therewith.
 
        (d) In the event of termination of Executive's employment for any reason
    provided in this paragraph 6, all rights and obligations of the Company and
    Executive under this Agreement shall cease immediately, except that

or non-competition covenant in favor of a former employer or any other person or
entity (other than the Company and its subsidiaries), and that the execution of

Employee to perform any services which interfere with the performance of
Employee's duties under this Agreement.
 
    5.  CONFIDENTIALITY, NON-DISCLOSURE AND OWNERSHIP OF CONFIDENTIAL
INFORMATION.  The Employee acknowledges that during his employment, he will gain
access to, or possession or knowledge of, numerous trade secrets, confidential
information and other valuable properties, including, but not limited to,
hospital and healthcare facility client lists, client files and records, lists
of potential clients, prospects or targets, and/ or other market and marketing

manuals and plans, business and sales techniques and research and development
(hereinafter referred to collectively as "Confidential Information").
Confidential Information shall not include information in the public domain or
attainable from information generally available to the public. Employee
acknowledges that such Confidential Information is unique and a valuable asset
which is owned solely by Employer and is to be used only for Employer's benefit.
Employee shall not, during or after the term of employment, disclose, divulge,
reveal, transfer, reproduce, sell, capitalize upon or take advantage of such
Confidential Information and in addition, Employee shall exercise all reasonable
efforts and precautions to protect such Confidential Information form
misappropriation, misuse, disclosure, breach of confidentiality, or other
conduct or action inconsistent with Employer's rights. Upon termination,
Employee shall return immediately to Employer all Employer's property
(including, without limitation, Confidential Information) in Employee's
possession or control.
 
    6.  CONFIDENTIAL INFORMATION: COVENANT NOT TO COMPETE.
 
    a.  Employer acknowledges that Employee has previously been involved in an
       executive capacity for a long period of time in the healthcare services
       business and that Employee has acquired substantial knowledge concerning
       that business as a result of such experience. Employee acknowledges that
       his
 
                                       2
<PAGE>
       contact with physicians and medical institutions as a result of his
       employment by Employer will result in a personal relationship being
       established between Employee and such physicians and/or the
       administration of such medical institutions whereby Employee could
       influence the future actions of such medical institutions and/or
       physicians relative to the renewal or cancellation of contractual
       relationships between Employer, its subsidiaries and/or affiliates and
       such medical institutions and/or physicians. Furthermore, Employee
       acknowledges and agrees that Employee's employment by Employer will
       result in the acquisition by Employee of confidential information
       concerning the method of operation and administration of Employer and its
       subsidiaries and affiliates and of medical institutions and physicians
       with whom Employer and its subsidiaries and affiliates transact business,
       including, but not limited to, fee schedules, formulas and special client
       requirements. Employee acknowledges and agrees that such confidential
       information would create an unfair advantage in the event Employee were
       to attempt to solicit or provide services of a similar nature to a
       medical client of Employer, its subsidiaries or affiliates.
 
            Accordingly, Employee agrees not to disclose Confidential
        Information and agrees not to interfere with the contractual
        relationship between Employer, its subsidiaries, and/or affiliates and
        any medical institution and/or physician for a period of two (2) years
        after termination of employment.
 
    b.  Employee agrees, during the term hereof, and for a period of two (2)
       years following the termination of employment hereunder, that he will
       not, directly or indirectly, by himself, or as a shareholder, employee,
       director, officer, partner, contractor or agent of another, enter into
       any business or activity anywhere within 100 miles of any location in
       which Employer or any of its subsidiaries or affiliates conducts
       non-transportation business in competition with Employer or its
       subsidiaries or affiliates and that would involve the following: (i) the
       solicitation of hospitals or other healthcare facilities to provide
       emergency department, kidney dialysis, or healthcare management services
       or other contract physician services similar to or in competition with
       such services provided by Employer or any of its subsidiaries or
       affiliates providing similar services; or (ii) the solicitation of
       hospitals or other healthcare facilities that are clients or prospective
       clients (potential clients as to which a marketing presentation has been
       made within six (6) months of the date of termination of this Agreement)
       of Employer to provide any physician staffing, recruitment or management
       services similar to or in competition with services provided by Employer
       or its subsidiaries and with which Employee was associated.
       Notwithstanding the foregoing, Ownership of up to 5% of the outstanding
       equity or debt securities of any publicly traded entity which engages in
       such activities shall not of itself constitute a breach of this
       Agreement.
 
    c.  Employee acknowledges that Employer is a party to those certain
       Professional Services Agreements with Columbia/HCA Healthcare Corporation
       ("Columbia") dated as of February 1, 1996 and October 1, 1996,
       respectively, (collectively, the "Columbia Agreements") whereby Employer
       provides services to certain Columbia facilities ("Facilities"). Employee
       agrees that, for a period commencing on the date hereof and continuing
       until two (2) years following termination of the Columbia Agreements, he
       will not, without prior written approval of Columbia, either individually
       or as an employee, agent, officer or director of a third party, directly
       or indirectly (i) render any professional, administrative, advisory or
       consulting services to or for any physician clinic, independent physician
       organization or similar physician organization within a ten mile radius
       of any hospital or similar facility to which Employer has provided
       services under the Columbia Agreements, or (ii) solicit, raid, entice or
       induce any person who is (or was at any time within the one year period
       immediately preceding such termination) an employee or independent
       contractor of any Facility to (y) terminate his employment or contract
       with such Facility, or (z) become employed by or contract with any other
       person, firm, or corporation, and Employee will not approach any such
       employee or independent contractor for such purpose or authorize or
       knowingly approve the taking of such actions by any other persons.
 
                                       3
<PAGE>
    7.  SOLICITATION OF OTHER EMPLOYEES.  Employee shall not, until two (2)
years subsequent to the termination of employment, solicit or seek to influence,
either directly or indirectly, any employee or any physician or healthcare
provider under contract with Employer or any of its subsidiaries or affiliates,
to enter into any employment agreements, independent contractor arrangement, or
any other contractual arrangement whereby such individual would perform services
for compensation, either directly or indirectly, for any person, firm,
corporation or other entity or business that provides products or services in
competition with the Employer or any of its subsidiaries or affiliates.
 
    8.  TRANSFER OF AMERICAN COMMON STOCK.  Employee acknowledges and agrees
that as an executive he will be subject to American's policies with respect to
transactions in American Common Stock, as such policies are in effect from time
to time. Employee acknowledges that, as of the Effective Date, he is the owner
of 703,730 shares (the "Employee Shares") of the common stock of American, $.01
par value ("American Common Stock"), which Employee Shares represent all of the
shares of American Common Stock held by Employee. In the event that Employee
shall, without the prior written consent of American, sell, assign, pledge,
hypothecate or otherwise dispose of, directly or indirectly, any Employee Shares
(including any shares of American Common Stock distributed in respect of the
Employee Shares), except in such amounts and on or following such dates (the
"Release Dates") set forth on SCHEDULE A hereto, Employee shall pay to Employer
on or as soon as practicable following each such Release Date the product of (y)
the number of shares of American Common Stock sold by Employee in excess of that
permitted hereunder as of such Release Date (the "Excess Shares"), and (z) the
