Schedule "1" hereto (collectively, the "Shareholders" and, individually, a
"Shareholder") and amends and restates in its entirety that certain Stock
Purchase Agreement dated March 31, 1998, by and among SuperShuttle, Southern and
the Shareholders.

                                    RECITALS

         A. SuperShuttle and Southern are parties to a letter agreement dated
February 25, 1998 (the "Letter of Intent"), and SuperShuttle, Southern and the
Shareholders are parties to that certain Stock Purchase Agreement dated March
31, 1998, which contemplates the acquisition by SuperShuttle of all of the
outstanding capital stock of Southern.

         B. The Shareholders currently and collectively own all of the issued
and outstanding shares of capital stock of Southern, with each Shareholder
owning the number of shares set forth opposite such Shareholder's name on
Schedule 1.

         C. The Shareholders are joined herein for purposes of affirming the
representations and warranties made in Article 3, and to otherwise be bound
hereto for the obligations of Southern for which they are jointly and severally
liable.

         NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements herein contained, the parties agree as follows:

                                    ARTICLE 1
                               THE STOCK PURCHASE

         1.1 Basic Transaction.

                  (a) On and subject to the terms and conditions of this
         Agreement, SuperShuttle agrees to purchase from the Shareholders, and
         each of the Shareholders agrees to sell to SuperShuttle, all of his or
         her shares of capital stock of Southern (the "Southern Common Stock")
         and the Shareholders agree to purchase from SuperShuttle, and
         SuperShuttle agrees to sell to the Shareholders, 978,882 shares of
         Common Stock, $0.01 par value per share, of SuperShuttle (the
         "SuperShuttle Common Stock"), pro rata to their Southern Common Stock
         ownership as reflected on Schedule 1 (hereinafter, the "Exchange"). The
         aggregate number of shares of SuperShuttle Common Stock to be issued in
         order to give effect to this provision will represent fifteen percent
         (15%) on a fully-diluted basis of the total number of outstanding
         shares of SuperShuttle Common Stock when issued (after giving effect to
         any SuperShuttle Common Stock issued in connection with the
         contemporaneous

                                        1
   7
         acquisitions of the Los Angeles and Orange County franchisees and AAA
         Wheelchair Wagon Services, Inc., Wheelchair Ambulance of Hollywood,
         Inc., Limousines of South Florida, Inc. and A1A Snowbird Leasing, Inc.
         and the conversion of the currently outstanding shares of
         SuperShuttle's Series B Convertible Preferred Stock into shares of
         SuperShuttle Common Stock).

                  The number of shares of SuperShuttle Common Stock to be issued
         to the Shareholders shall be adjusted to reflect fully the effect of
         any stock split, reverse split, stock dividend (including any dividend
         or distribution of securities convertible into SuperShuttle Common
         Stock or Southern Common Stock), reorganization, recapitalization or
         other like change with respect to SuperShuttle Common Stock or Southern
         Common Stock occurring after the date hereof and prior to the Effective
         Time, but shall not be adjusted for the exercise of any outstanding
         SuperShuttle options or warrants convertible into SuperShuttle Common
         Stock. No fractional shares of SuperShuttle Common Stock shall be
         issued. Fractional shares of such stock shall be rounded up to the
         nearest whole share.

                  (b) SuperShuttle agrees to grant the Shareholders registration
         rights pursuant to the terms of the Registration Rights Agreement, a
         form of is attached hereto as Exhibit "A."

                  (c) As an incident to the share exchange transactions and as a
         predicate and condition to them, certain assets are required to be
         transferred into Southern or other accommodations made in order to
         effect the purpose of allowing Southern to operate the business of
         Southern as presently conducted. In this regard, the assets described
         on Schedule 1.1(a) attached hereto and incorporated by reference herein
         shall be assigned to Southern immediately prior to the Effective Time.
         It is acknowledged by the parties hereto that any and all radio
         frequencies, real estate interests, permits, and similar assets
         necessary to the conduct of the business of Southern immediately prior
         to the Effective Time shall be and become the property of Southern
         effective upon the Exchange through the processes described on Schedule
         1.1(a) without any further form of consideration or payment owing to
         Southern or any of the Shareholders. As an incident to the share
         exchange transactions and as a predicate and condition to them, certain
         assets are required to be transferred from Southern to third parties or
         affiliates. In this regard, the assets described on Schedule 1.1(b)
         attached hereto and incorporated by reference herein and any
         indebtedness relating hereto shall be transferred to the party
         identified therein on or before April 30, 1998. The transactions
         contemplated by Schedules 1.1(a) and 1.1(b) are a fundamental part of
         this Agreement and the consummation of those transactions is a
         condition to the effectiveness of the Agreement.

         1.2 Effective Time; Closing Date. The date and time when the share
exchange shall become effective, March 31, 1998, is referred to as the
"Effective Time." The closing of the transactions contemplated hereunder (the

   8
satisfaction or waiver of the conditions provided at Article 7, or (ii) April
30, 1998 (the "Closing Date") at the offices of Shareholders' counsel, or such
other place as the parties may agree.

         1.3 Articles of Incorporation and Bylaws. The Articles of Incorporation
and the Bylaws of Southern shall be restated in the forms of Exhibits "B" and
"C" hereto and incorporated herein.

         1.4 Deliveries at the Effective Time. At the Effective Time, each of
the Shareholders shall surrender the certificate or certificates representing
shares of Southern Common Stock to the Escrow Agent. Promptly following
surrender, SuperShuttle shall issue the SuperShuttle Common Stock to the
Shareholders pursuant to Section 1.1. The certificates of Southern Common Stock
surrendered to the Escrow Agent shall be duly endorsed and otherwise in proper
form for transfer as SuperShuttle may require. Escrow Agent shall not be
obligated to deliver the consideration to which any Shareholder is entitled as a
result of the share exchange until such Shareholder surrenders his or her
certificate or certificates representing the shares of Southern Common Stock to
be exchanged.

         1.5 Closing of Southern Transfer Books. At the Effective Time, the
stock transfer books of Southern shall be closed and no transfer of shares of
Southern Common Stock issued and outstanding immediately prior to the Effective
Time shall thereafter be made (except as provided for or contemplated in Section
1.1 above).

         1.6 Lost, Stolen or Destroyed Certificates. In the event any
certificates representing shares of Southern Common Stock shall have been lost,
stolen or destroyed, SuperShuttle shall issue in exchange for such lost, stolen
or destroyed certificates, upon the making of an affidavit of that fact by the
holder thereof, such shares of SuperShuttle Common Stock as required pursuant to
Section 1.1; provided, however, that SuperShuttle 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 an indemnity agreement in such form
as SuperShuttle may reasonably direct as indemnity against any claim that may be
made against SuperShuttle with respect to the certificates alleged to have been
lost, stolen or destroyed.

         1.7 Taking of Necessary Action; Further Action. SuperShuttle, on the
one hand, and Southern on the other hand, shall use reasonable best efforts to
take all such actions (including, without limitation, actions to cause the
satisfaction of the conditions of the other to effect the share exchange) as may
be necessary or appropriate in order to effectuate the Exchange as promptly as
possible. If, at any time after the Effective Time, any further action is
necessary or desirable to carry out the purposes of this Agreement, the officers
and directors of the SuperShuttle are fully authorized in the name of Southern
or otherwise to take, and shall take, all such lawful and necessary actions.

         1.8 Tax Treatment. The parties hereto acknowledge and agree that the
transactions contemplated hereby are intended to be a tax free reorganization
under Section 368(a)(1)(B) of the U.S. Internal Revenue Code of 1986, as amended

paid; Southern's reserves and provisions for taxes on the balance sheets
included in the Southern Financial Statements are sufficient for all accrued and
unpaid taxes as of the dates of such balance sheets; Southern has paid all taxes
due and payable by it or which it is obligated to withhold from amounts owing to
any employee, creditor, or third party; Southern has not waived any statute of
limitations in respect of taxes or agreed to any extension of time with respect
to a tax assessment or deficiency; and Southern has not received notice of any
unresolved questions or claims concerning the tax liability of Southern.
Southern has not filed any consent agreement under Section 341(f) of the Code or
agreed to have Section 341(f)(2) of the Code apply to any disposition of a
"subsection (f) asset" as defined in Section 341(f)(4) of the Code) owned by
Southern. Southern (i) is not and has not been a member of an affiliated group
filing a consolidated federal income tax return (other than an affiliated group
the common parent of which was Southern) and (ii) does not have any liability
for taxes of any person (other than Southern) under Treasury Regulation Section

transferee or successor by contract or otherwise. Southern is not a party to a
tax sharing or allocation agreement nor does Southern owe any amount under any
such agreement. Southern is not obligated to make any payments and is not a
party to any agreement that under certain circumstances could obligate it to
make any payments that, either in whole or in part, would be nondeductible under
Sections 280G or 162 of the Code. Southern has not been a "United States real
property holding corporation" (within the meaning of Section 897(c)(2) of the
Code) at any time within the applicable period specified in Section
897(c)(1)(A)(ii) of the Code.

                  (a) The Southern Disclosure Schedule lists all of Southern's
         federal, state and foreign registrations of trademarks, service marks
         and other marks, trade names or other trade rights, and all pending
         applications for any such registrations, all other trademarks and other
         marks, trade names and other trade rights, or in which Southern has any
         interest whatsoever, and all other trade secrets and other intellectual
         property rights, whether or not registered, created or used by or on
         behalf of Southern, in each case relating to its business
         (collectively, "Intellectual Property Rights"). The Intellectual
         Property Rights listed in the Southern Disclosure Schedule are all
         those used by Southern in connection with its business.

                  (b) Except as set forth on the Southern Disclosure Schedule,
         Southern has full legal right, title and interest to the Intellectual
         Property and has not granted any rights in or to the same to any third
         party. To the knowledge Southern and except as set forth on the
         Southern Disclosure Schedule, conduct of the business as presently
         conducted and the conduct, use and exploitation of the Intellectual
         Property does not infringe or misappropriate any rights held or
         asserted by any person or entity and no person or entity is infringing
         on the Intellectual Property. Except as set forth on the Southern
         Disclosure Schedule, no payments are required for the continued use of
         the Intellectual Property. None of the Intellectual Property has ever
         been declared invalid or unenforceable or is the subject of any pending
         or to the knowledge of Southern threatened action for opposition,
         cancellation, declaration, infringement or invalidity, unenforceability
         or misappropriation or like claim, action or proceeding.

         3.16 Litigation. Except as set forth in the Southern Disclosure
Schedule, there are no actions, suits, proceedings, orders or investigations
pending or, to the knowledge of Southern, threatened against Southern, at law or
in equity, or before or by any federal, state, municipal or other governmental
department, commission, board, bureau, agency or instrumentality, domestic or
foreign, which, if determined adversely to Southern, would result in a material
adverse effect to Southern's operations and financial condition and there is no
basis known to Southern for any of the foregoing. Except as set forth in the
Southern Disclosure Schedule, Southern has not received any opinion or legal
advice to the effect that Southern is exposed from a legal standpoint to any
material liability. No governmental entity has at any time challenged or
questioned the legal right of Southern to offer or provide any of its services
in the present manner or style thereof.

problems pending; and (iii) its labor relations are satisfactory in all material
respects.

currently maintained are in full force and effect and Southern is not in default
with respect to its obligations under any of such insurance policies. All
premiums have been paid and there is no retroactive premium adjustment
obligation of any kind or character. There is no claim of Southern pending under
any of such policies or bonds as to which coverage has been questioned, denied
or disputed by the underwriters of such policies or bonds. Southern has no
knowledge of any threatened termination of, or material premium increase with
respect to, any such policies.

         3.21 Insider Transactions. Except as set forth herein or in the
Southern Disclosure Schedule, no officer, director or shareholder of Southern or
any member of the immediate family of any such officer, director or shareholder,
or any entity in which any of such persons owns any beneficial interest (other
than a publicly-held corporation whose stock is traded on a national securities
exchange or in the over-the-counter market and less than 5% of the stock of
which is beneficially owned by any of such persons) (collectively "Insiders"),
has any agreement with Southern or any interest in any property, real, personal
or mixed, tangible or intangible, used in or pertaining to the business of
Southern. For purposes of the preceding sentence, the members of the immediate
family of an officer, director or shareholder shall consist of the spouse,
parents, children, siblings, mothers- and fathers-in-law, sons- and
daughters-in-law, and brothers- and sisters-in-law of such officer, director or
shareholder.

         3.22 Compliance With Laws; Permits; Certain Operations. Southern and
its officers, directors, and to its knowledge agents and employees have complied
in all material respects with all applicable laws and regulations of foreign,
federal, state and local governments and all agencies thereof which affect the
business or any owned or leased properties of Southern and to which Southern may
be subject, and no claims have been filed against Southern alleging a violation
of any such law or regulation, except as set forth in the Southern Disclosure
Schedule. Without limiting the generality of the foregoing, Southern has not
violated, or received a notice or charge asserting any violation of, the
Occupational Safety and Health Act of 1970, or any other state or federal acts
(including rules and regulations thereunder) regulating or otherwise affecting
employee health and safety. Southern has not given or agreed to give any money,
gift or similar benefit (other than incidental gifts of articles of nominal
value) to any actual or potential customer, supplier, governmental employee or
any other person in a position to assist or hinder Southern in connection with
any actual or proposed transaction. Southern holds all permits, licenses,

                                       16
   22
certificates and other authorizations of foreign, federal, state and local
governmental agencies required for the conduct of its business, including
specifically the permits, licenses, certificates and other authorizations
described in Section 3.22 of the Southern Disclosure Schedule.

         3.23 Disclosure. Neither this Agreement nor any of the schedules or
exhibits hereto contains any untrue statement of a material fact or omits a
material fact necessary to make the statements contained herein or therein, in
light of the circumstances in which they were made, not misleading.

         3.24 Minute Books. The minute books of Southern shall be made available
to counsel for SuperShuttle and those delivered shall be the only minute books
of Southern and shall contain an accurate summary of all meetings of directors
(or committees thereof) and shareholders or actions by written consent since the
time of incorporation of Southern.

         3.25 Compensation. Any amounts paid, if any, as compensation or
otherwise to the Shareholders following the Effective Time shall equal the fair
value for services provided by the Shareholders to Southern and/or to
SuperShuttle.

         3.26 Medicaid and Other Third Party Payor Matters.

                  (a) To the best of Southern's knowledge, Southern has met and
         continues to meet without material exception, all State and Federal
         laws and regulations governing participation in the Third Party Payor
         programs and plans, all of the terms and conditions set forth in the
         Third Party Payor agreements and all of the terms and conditions for
         participation in the health care plans described in the Third Party
         Payor agreements. In addition, Southern has not received any notice
         from any governmental or public body, agency or instrumentality
         alleging that the operation of Southern is not in accordance with
         regulations affecting its certifications or participation in any Third
         Party Payor program.

                  (b) Except as otherwise set forth in the Southern Disclosure
         Schedules, there is no claim, action, temporary restraining order,
         injunction, suit, proceeding, inquiry or investigation, at law or in
         equity, before or by an internal board or body of Southern, any
         external board, body or entity chosen, retained or hired by Southern,
         any judicial or administrative court, governmental agency, public board
         or body, pending, contemplated or, to the best of Southern's knowledge,
         threatened against Southern, nor is there any basis therefore wherein
         an unfavorable decision, ruling or finding would in any way adversely
         affect Southern's compensation and/or reimbursement under the Third
         Party Payor agreements.

                                    ARTICLE 4

         4.2 Execution and Delivery; No Conflicts.

                  (a) This Agreement has been duly executed and delivered by
         Shareholder and the agreements of Shareholder contained herein
         constitute the valid and binding obligations of the Shareholder,
         enforceable against Shareholder in accordance with their terms, except
         as the same may be limited by bankruptcy, insolvency, reorganization,
         moratorium, or other laws affecting generally the enforcement of
         creditors' rights.

                  (b) The execution, delivery and performance of this Agreement
         by Shareholder and the consummation of the transactions contemplated
         hereby (i) have been duly and validly authorized by all necessary
         action on the part of the Shareholder; and (ii) are not prohibited by,
         do not violate any provision of, and will not result in the breach of,
         or accelerate or permit the acceleration of the performance required by
         the terms of any applicable law, rule, regulation, judgment, decree,
         order or other requirement of the United States or any state of the
         United States, or any court, authority, department, commission, board,
         bureau, agency or instrumentality of either thereof, in a manner which
         would have a material adverse affect on the ability of the Shareholder
         to enter into and consummate this Agreement, or any material contract,
         indenture, agreement or commitment to which Shareholder is a party or
         is bound in a manner which would have a material adverse affect on
         Shareholder.

         4.3 Consents and Approvals. The execution, delivery and performance by

or similar payment.

         4.5 Securities Laws Compliance. The securities to be acquired by
Shareholders under the terms of this Agreement will be acquired for
Shareholder's own account for the purpose of investment and not with the present
intention of public resale or public distribution of all or any part of the
securities. Each Shareholder agrees that he/she will refrain from transferring
or otherwise disposing of any of the securities, or any interest therein, in
such manner as to violate

                                       18
   24
the Securities Act of 1933 (the "Securities Act") or of any applicable state
securities law regulating the disposition thereof. Shareholder agrees that the
certificates representing the securities shall bear legends to the effect that
such securities have not been registered under the Securities Act or any
applicable state securities laws and that no interest therein may be transferred
or otherwise disposed of in violation of the provisions thereof or of the rules
and regulations issued thereunder.

         investor in the shuttle transportation business and has such knowledge
         and experience in such matters that it is capable of evaluating the
         risks and merits of acquiring the SuperShuttle securities. The
         Shareholder has not been formed or organized for the specific purpose
         of acquiring the securities. The Shareholder has had, during the course
         of this transaction and prior to its acquisition of the SuperShuttle
         securities, the opportunity to ask questions of, and receive answers
         from, SuperShuttle and its management concerning SuperShuttle and the
         terms and conditions of this Agreement. The Shareholder hereby
         acknowledges that it or its representatives has received all such
         information as it considers necessary for evaluating the risks and
         merits of acquiring the securities and for verifying the accuracy of
         any information furnished to it or to which it had access.

                  (c) The Shareholder has had the opportunity to consult with
         financial advisers and counsel of its own choosing in making an
         informed decision with respect to the Exchange consideration and has
         consulted with counsel of its own choosing in making an informed
         decision with respect to the terms of this Agreement.

         substantially similar premiums are in full force and effect; and

                  (h) Southern shall promptly notify SuperShuttle if Southern
         learns of any dispute between Southern and any governmental or
         regulatory body which, if adversely determined, would have a material
         adverse effect, (ii) any material change in the manner, method or
         procedure of Medicaid reimbursement in the State of Florida, or notice
         from any governmental or public body, agency or instrumentality that
         Southern is proposed to be excluded, suspended or debarred from any
         governmental health care program advising that Southern is not in
         compliance with statutes or regulations affecting its operations,
         including statutes and regulations under the Medicaid program.

         5.2 Conduct Subsequent to the Exchange.

                  (a) The Share Exchange shall be rescinded automatically
         without further notice (the "Recision") upon the occurrence of any of
         the following events: (i) if SuperShuttle does not file a registration
         statement for an initial public offering on Form S-1 with the SEC by
         May 31, 1998 to register for sale shares of SuperShuttle Common Stock;
         (ii) if the SEC does not declare such registration statement effective
         by July 31, 1998, or (iii) if the underwritten initial registration
         statement for an initial public offering on a firm commitment basis
         does not close by August 10, 1998, providing a per share offering price
         to the public of at least $6.50.

                  (b) As security for each party's rights of recision hereunder,
         the parties designate Akerman, Senterfitt & Eidson, P.A. as escrow
         agent (the "Escrow Agent") to hold: (i) the stock certificates in
         Southern formerly held by the Shareholders to be held for the benefit
         of SuperShuttle; and (ii) the stock certificates in SuperShuttle issued
         hereunder for the benefit of the Shareholders as their respective
         interests may appear in accordance with Schedule 1. If this Agreement
         is rescinded in accordance with Section 5.2(a), the Escrow Agent shall
         immediately, and without any further action by any party, deliver (a)
         to SuperShuttle the stock certificates of SuperShuttle, which
         certificates shall be immediately canceled, and (b) to each Shareholder
         the stock certificates of Southern delivered by each Shareholder to the
         Escrow Agent. During the period in which the stock

                                       21
   27
         certificates as held in escrow, the Escrow Agent shall vote the
         SuperShuttle Common Stock as directed by the Shareholders and shall
         vote the Southern Common Stock as directed by SuperShuttle.

                  (c) If this Agreement is rescinded, the parties' rights and
         obligations shall cease as if this Agreement never existed, except for
         the indemnification provisions set forth in Section 5.2(d) below.
         SuperShuttle, Southern and each Shareholder upon recision agrees to
         treat this transaction as rescinded effective as of the Effective Time
         and file all tax returns, reports or other statements consistent with
         such agreement.

                  (d) In the event that the Share Exchange is rescinded,
         SuperShuttle shall indemnify and hold the Shareholders and Southern
         harmless from and against the aggregate of all expenses, losses, costs,
         deficiencies, liabilities and damages, including, without limitation,
         related counsel and paralegal fees and expenses incurred or suffered by
         the Shareholders or Southern arising out of or resulting from a breach
         by Super Shuttle of any covenant or agreement as set forth in Section
         5.3 and a breach of the representation set forth in Section 2.13.

         5.3 SuperShuttle Recision Right. SuperShuttle shall have the option to
rescind the Share Exchange if Southern has not received the written approval of
the Aviation Department for Dade County of the changes in ownership of Southern
to Supershuttle by the effective date of SuperShuttle's registration statement
on Form S-1.

         5.4 Conduct by SuperShuttle. During the time from the Closing Date to
such time as the Share Exchange is rescinded or until the Recision rights expire
(the "Option Period"), SuperShuttle shall not take any action which could affect
the Recision rights and affect the ability of the Shareholders to then operate
Southern as if the exchange never occurred, including, but not limited to:

                  (a)      Cancellation of any material contracts;

                  (b)      Combining any operations, duties or tasks of Southern
                           with and into any operations of SuperShuttle or its
                           subsidiaries;

                  (c)      Combining any employee benefit plans with the plans
                           of SuperShuttle;

                  (d)      Pledging, encumbering or incurring any liens upon the
                           assets, properties, business or the shares of
                           Southern (the "Transferred Assets");

                  (e)      Declaring any dividends in property or cash;

                  (f)      Taking any of the actions contemplated by Section
                           5.1;

                                       22
   28
                  (g)      Using or allowing the use of the Transferred Assets
                           to satisfy any judgments or claims.

In addition, during the Option Period, the board of directors of Southern will
be comprised of three members: Mark Levitt, Karen N. Caputo and a designee of
SuperShuttle and Mark Levitt shall remain as President. If the Share Exchange is
rescinded, the SuperShuttle designee shall immediately resign from the board of
directors of Southern. Upon the expiration of the Recision rights, the board of
directors of Southern will be comprised of: R. Brian Wier, Thomas C. LaVoy and a
designee of the Shareholders.

                              ADDITIONAL AGREEMENTS

         6.1 Expenses. Each of SuperShuttle and Southern shall bear their own
legal and accounting fees and other expenses relating to this transaction. In
addition, Southern will bear the expenses associated with the conduct of the
required accounting audit of its books and records relating to this transaction.

         6.2 No Negotiations. Until March 31, 1998, or such later date as the
parties may mutually agree, Southern and the Shareholders agree that neither
they nor Southern's directors, officers, employees or agents (i) shall solicit,
negotiate or accept any offers for the sale of Southern or any substantial
portion thereof (whether by merger or sale of stock or assets or otherwise) or
provide any non-public information with respect thereto, or (ii) shall solicit,
negotiate, or accept any offers for the acquisition of any material business.
Southern shall promptly notify SuperShuttle if it (or to its knowledge any of
the other enumerated persons or any Shareholder) is approached by any person
interested in acquiring the assets or capital stock of Southern.

         6.3 Notification of Certain Matters. SuperShuttle and Southern shall
give prompt notice to each other of (i) the occurrence or failure to occur of
any event, which occurrence or failure would be likely to cause any
representation or warranty on its part contained in this Agreement to be untrue
or inaccurate at, or at any time prior to, the Effective Time, and (ii) any
material failure of such party, or any officer, director, shareholder, employee
or agent thereof, to comply with or satisfy any covenant, condition or agreement
to be complied with or satisfied by it hereunder.

         6.4 Access to Information; Confidentiality.

                  (a) Until March 31, 1998, or the Effective Time each of
         SuperShuttle and Southern shall have the opportunity to make a complete
         review of the books, records, business and affairs of Southern or
         SuperShuttle, as applicable. Such review may be conducted at any and
         all reasonable times by such persons as SuperShuttle or Southern
         designates. To facilitate such review, the parties shall provide to the
         other party and its agents complete access to all of its records and
         documents, shall provide the other party

                                       23
   29
         with personal, bank and professional references, and shall use
         reasonable efforts to make available for consultation customers,
         employees, suppliers and distribution channels.

                  (b) Each of SuperShuttle and Southern agrees that all
         non-public information provided to the other enumerated parties will be
         treated as confidential, and if this Agreement is terminated, will
         return to such other parties all confidential documents (and all copies
         thereof) in its possession, or will certify to the other parties that
         all such documents not returned have been destroyed. Further,
         regardless of whether this Agreement is terminated, each party shall
         continue to hold all confidential information of the other in strictest
         confidence in accordance with the Letter of Intent entered into by
         SuperShuttle and Southern on February 25, 1998.

         6.5 Consents; Approvals. SuperShuttle and Southern shall each use their
reasonable best efforts to obtain all consents, waivers, approvals,
authorizations or orders, and each such party shall make all filings required in
connection with the authorization, execution and delivery of this Agreement by
such party and the consummation by them of the transactions contemplated hereby.
Each of SuperShuttle and Southern shall furnish all information required to be
included for any application or filing to be made pursuant to the rules and
regulations of any applicable governmental body in connection with the
transactions contemplated by this Agreement.

         6.6 Supplements to Disclosure Schedules. From time to time prior to the
Effective Time, SuperShuttle and Southern will each promptly supplement or amend
their respective Disclosure Schedules with respect to any matter hereafter
arising which, if existing or occurring at the date of this Agreement, would
have been required to be set forth or described in any such Disclosure Schedule
or which is necessary to correct any information in any such Disclosure Schedule
which has been rendered inaccurate thereby. No supplement or amendment to any
such Disclosure Schedule shall have any effect for the purpose of determining
satisfaction of the conditions set forth in Sections 7.2 or 7.3 of this
Agreement, as the case may be, except as otherwise provided in Sections 7.2(a)
and 7.3(a).

         6.7 Non-Solicitation of Employees. For a period of one year from the
date hereof, no party shall solicit, negotiate with or hire any employee of the
other party.

         6.8 Election of Directors. SuperShuttle shall promptly after the date
hereof take all action necessary in accordance with Delaware Law and its
Certificate of Incorporation and Bylaws to (i) increase, effective as of the
Effective Time, the number of directors serving on the SuperShuttle Board of
Directors to accommodate the election of one (1) designee of Southern
(designated collectively with AAA Wheelchair Wagon Service, Inc. and Limousines
of South Florida, Inc.); (ii) elect, effective as of the Effective Time, that
one designee to SuperShuttle's Board of Directors; and (iii) appoint such
designee to Supershuttle's "pricing committee" of the Board of Directors.

         6.9 Confidential Information and Covenant Not To Compete. Each of the
Shareholders hereby covenants and agrees as follows:

                                       24
   30
                  (a) at any time following execution of this Agreement and
         consummation of the Exchange transactions, unless the Share Exchange
         Agreement is rescinded the Shareholder shall not use or disclose,
         directly or indirectly, for any reason whatsoever or in any way any
         confidential information or trade secrets of Southern or SuperShuttle,
         including by way of example, names or descriptions of customers,
         financial statements, product or service pricing or other information,
         contract proposals and bidding information, and any and other
         information of a proprietary or confidential character;

                  (b) that until the later of three (3) years following the
         consummation of the Exchange transactions or termination of the
         employment agreement referenced in Section 7.1(d), the Shareholder
         shall not, directly or indirectly, either as an employee, employer,
         consultant, agent, principal, partner, stockholder, corporate officer,
         director or in any other capacity whatsoever, engage or participate in
         any businesses in competition in any manner whatsoever with the
         business of Southern, SuperShuttle or any affiliate of either of them
         as such business is presently conducted (the "Business") in either
         Dade, Palm Beach, Broward and Orange Counties, Florida (the "Applicable
         Counties"). Not limiting the generality of the foregoing, the business
         of Southern and SuperShuttle shall be deemed to consist of the
         transportation, over land, of passengers for hire, including, by way of
         example, transportation to and from airports, ports or stations of
         embarkation for travel. In addition, until the expiration of five years
         following the consummation of the Exchange transactions the
         Shareholder, shall not enter into any agreement with a party currently
         doing business with Southern, Super Shuttle or any affiliates of either
         of them for the provision of services substantially similar to those
         provided currently. Notwithstanding the foregoing the parties
         acknowledge that Robert Siedlecki currently holds certain interests in
         the taxi cab business, and such current interests and future expansion
         of such business shall not be a violation of Subsections 6.9(b) and
         (c).

                  (c) from and after the date of this Agreement, the Shareholder
         shall not solicit or negotiate any contract or agreement that
         constitutes or would constitute engaging in competition with the
         Business of Southern or SuperShuttle in the Applicable Counties;

                  (d) each of the Shareholders by execution of this Agreement
         assigns to Southern any and all rights and interests in the business
         concept employed by Southern to the extent that they have any interest
         therein, and in any name under which such businesses may have been
         conducted, and agree not to undertake to conduct business employing any
         such name or business concept at any place at which SuperShuttle or any
         of its affiliates conduct business.

In the event that the Share Exchange Agreement is rescinded, this Section 6.9
shall be void and of no further effect and any employment agreement between
Southern and a Shareholder in effect shall be terminated and the non-competition
provisions hereof shall immediately terminate.

         The Shareholders hereby specifically acknowledge and agree that the
temporal, geographical and other restrictions contained in this Section 6.9 are
reasonable and necessary to

                                       25
   31
protect the business and prospects of Southern and SuperShuttle and that the
enforcement of the provisions of this Section 6.9 will not work an undue
hardship on the Shareholders. Shareholders further agree that in the event that
either the temporal, geographical or any other restrictions, or a portion
thereof, set forth in this Section 6.9 is determined to be overly restrictive
and nonenforceable, the covenants set forth shall be reduced and modified to
those which are reasonable and enforceable under the circumstances to the
fullest extent permitted under applicable law in the judgment of the applicable
court. The Shareholders acknowledge and agree that SuperShuttle does not have an
adequate remedy at law for the breach or threatened breach of the covenants
contained in this Section 6.9 and the Shareholders therefore specifically agree
that SuperShuttle may, in addition to any other remedies which may be available
hereunder or as a matter of law or in equity, file a suit in equity to enjoin
the Shareholder from the breach or threatened breach.

         If the provisions of this Section 6.9 are held to be invalid or
unenforceable as against public policy, the remaining provisions of this
Agreement shall not be affected thereby.

         6.10 Collateral and/or Guarantees for Certain Southern Loans. As soon
as practical after the expiration of the Recision rights, SuperShuttle shall
take such steps to replace (i) the personal guarantees of the Shareholders on
certain Southern loans and (ii) the cash collateral pledged by certain
Shareholders to secure certain bonds and letters of credit established on behalf
of Southern. Notwithstanding the foregoing, Southern may at its option, replace
such personal guaranties and cash collateral with such bonds as are acceptable
to the lender.

         6.11 Shareholder Loans. The Shareholder loans reflected on the books of
Southern, which are listed on Schedule 6.11 hereto, shall be forgiven by
Southern.

         6.12 Tax Treatment. The parties hereto will use their respective best
efforts to cause the Exchange to be a tax free reorganization under Section
368(a)(1)(B) of the Code and do not intend to take any action after the
Effective Date to cause the Exchange to lose its tax free status. All parties
hereto agree to file the Share Exchange Agreement with its respective Federal
Income Tax returns in the year in which the Exchange is effective and to comply
with the reporting requirements. The parties shall take no action with respect
to the Share Exchange to jeopardize such tax free status.

                                    ARTICLE 7

         directors of SuperShuttle and Southern;

                  (b) no temporary restraining order, preliminary or permanent
         injunction or other order issued by any court of competent jurisdiction
         or other legal restraint or prohibition preventing the consummation of
         the Exchange shall be in effect, nor shall any proceeding brought by an
         administrative agency or commission or other governmental authority or
         instrumentality, domestic or foreign, seeking any of the foregoing be
         pending; and there shall not be any action taken, or any statute, rule,
         regulation or order enacted, entered, enforced or deemed applicable to
         the Exchange, which makes the consummation of the Exchange illegal;

                  (c) no party hereto shall have terminated this Agreement as
         permitted herein; and

                  (d) Southern and Mark Levitt shall have entered into an
         Employment Agreement substantially in the form attached hereto as

         and except for the updating or correction of the disclosures in the
         Southern Disclosure Schedule which do not reflect any change that is
         reasonably likely to have a material adverse effect on the assets,
         liabilities, business, results of operations, financial condition or
         prospects of Southern); and Southern shall in all material respects
         have performed each obligation and agreement and complied with each

         any of its subsidiaries of all or a material portion of the business or
         assets of SuperShuttle or any of its subsidiaries, or seeking to compel
