                              AMENDED AND RESTATED

                 AGREEMENT AND PLAN OF REORGANIZATION AND MERGER

         This AMENDED AND RESTATED AGREEMENT AND PLAN OF REORGANIZATION AND
MERGER (the "Agreement") is made as of March 31, 1998 by and among SUPERSHUTTLE
INTERNATIONAL, INC., a Delaware corporation ("SuperShuttle"); SUPERSHUTTLE
ACQUISITION COMPANY II, an Arizona corporation and a wholly owned subsidiary of
SuperShuttle ("Merger Sub"); TAMARACK TRANSPORTATION, INC., a California
corporation ("Tamarack"); and those Tamarack shareholders listed on Schedule "1"
hereto (collectively, the "Shareholders" and, individually, a "Shareholder").

                                    RECITALS

         A. SuperShuttle and Tamarack are parties to a letter agreement dated
March 2, 1998 (the "Letter of Intent"), which contemplates the acquisition by
SuperShuttle of all of the outstanding capital stock of Tamarack.

         B. SuperShuttle has caused the formation of Merger Sub for the purpose
of effecting the acquisition through a reverse triangular merger with and into
Tamarack.

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

         D. 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 Tamarack for which they are jointly and severally
liable.

         E. The parties have determined that it is in their respective interests
to merge Merger Sub with and into Tamarack (the "Merger") and to undertake such
other actions described herein, all on the terms and subject to the conditions
set forth in this Agreement.

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

                                    ARTICLE 1

                                   THE MERGER

         The respective boards of directors of SuperShuttle, Merger Sub and
Tamarack have, by resolutions duly adopted, approved the following provisions of
this Article 1 as the plan/agreement of merger required by Section  1108 of the
California Corporations Code, as amended (the "California Law") and Section
10-1107 of the Arizona Business Corporation Act, as amended (the "Arizona Law")
(collectively, the "Merger Statutes"), in connection with the Merger:

         1.1 The Merger, Incidental Transactions. At the Effective Time (as
defined in Section



                                       1
<PAGE>   7
1.3), in accordance with this Agreement, the Agreement and Plan of Merger
attached hereto as Exhibit "1.1" and the Merger Statutes, Merger Sub shall be
merged with and into Tamarack. The separate corporate existence of Merger Sub
(except as such existence may be continued by operation of law) shall cease, and
Tamarack shall continue as the surviving corporation. Tamarack, in its capacity
as the corporation surviving the Merger, sometimes is referred to herein as the
"Surviving Corporation." The parties shall use their reasonable best efforts to
undertake a corporate name change for the Surviving Corporation with the
California Secretary of State to "SuperShuttle Los Angeles, Inc." when expedient
to do so considering the California Public Utilities Commission (the "PUC")
process, among other factors.

                  As an incident to the Merger transactions and as a predicate
and condition to them, certain assets are required to be transferred into
Tamarack or other accommodations made in order to effect the purpose of allowing
the Surviving Corporation to operate the business of Tamarack as presently
conducted. In this regard, the assets described on Schedule 1.1 attached hereto
and incorporated by reference herein shall be transferred in the manner
contemplated by Schedule 1.1 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 Tamarack immediately prior to the Effective Time shall be and become
the property of the Surviving Corporation effective upon the Merger through the
processes described on Schedule 1.1 without any further form of consideration or
payment owing to Tamarack or any of the Shareholders. The transactions
contemplated by Schedule 1.1 are a fundamental part of this Agreement and the
consummation of those transactions is a condition to the effectiveness of the
Merger.

         1.2 Effect of the Merger. At the Effective Time, the Surviving
Corporation shall possess all the rights, privileges, immunities and franchises
of each of Merger Sub and Tamarack (collectively, the "Constituent
Corporations"); all property, real, personal and mixed, and all debts,
liabilities and duties due on whatever account, and all and every other interest
of or belonging to or due to each of the Constituent Corporations shall be taken
and deemed to be transferred to and vested in the Surviving Corporation without
further act or deed; and the Surviving Corporation shall be responsible and
liable for liabilities and obligations of each of the Constituent Corporations,
in each case in accordance with the Merger Statutes.

         1.3 Consummation of the Merger. As soon as is practicable after the
satisfaction or waiver of the conditions set forth in Sections 7.1, 7.2 and 7.3
of Article 7, the parties hereto shall cause the Agreement and Articles of
Merger to be delivered to the Arizona Corporation Commission of the State of
Arizona and the Agreement and officers' certificates of each Constituent
Corporation to be delivered to the Secretary of State of the State of
California, in such form as required by and executed in accordance with the
Arizona Law and the California Law, respectively. The Merger shall be effective
at such time as such documents are duly filed with (i) the Arizona Corporation
Commission of the State of Arizona, and (ii) the Secretary of State of the State
of California, which filings shall be made reasonably simultaneously. The date
and time when the Merger shall become effective is referred to as the "Effective
Time." It is contemplated that the conditions to consummation of the Merger will
be satisfied, if at all, on or before March 31, 1998, and that the Effective
Time shall be as soon as practicable following the satisfaction of the
conditions set forth in Sections 7.1, 7.2 and 7.3 of Article 7 hereof on or


                                       2
<PAGE>   8
before March 31, 1998.

         1.4 Articles of Incorporation and Bylaws; Directors and Officers. The
Articles of Incorporation and the Bylaws of the Surviving Corporation shall be
restated in the forms of Exhibits "A" and "B" hereto and incorporated herein.
The persons identified on Exhibit "C" shall be the directors and officers of the
Surviving Corporation at the Effective Time.

         1.5 Conversion of Securities. At the Effective Time, by virtue of the
Merger and without any action on the part of Merger Sub, Tamarack or the holders
of any of the following securities:

                  (a) Each share of Common Stock, no par value, of Tamarack (the
         "Tamarack Common Stock") issued and outstanding immediately prior to
         the Effective Time shall, by virtue of the Merger and without any
         action on the part of the holders thereof, automatically be canceled
         and extinguished and the total number of outstanding shares of Tamarack
         Common Stock shall be converted into and become a right to receive
         731,621 shares of Common Stock, $0.01 par value per share, of
         SuperShuttle (the "SuperShuttle Common Stock") (the "Exchange Ratio"),
         payable to the Shareholders pro rata to their Tamarack Common Stock
         ownership as reflected on Schedule 1. The aggregate number of shares of
         SuperShuttle Common Stock to be issued in order to give effect to this
         provision will represent approximately eleven percent (11%) of the
         total number of outstanding shares of SuperShuttle Common Stock when
         issued.

                  (b) Each share of Tamarack Common Stock issued and outstanding
         immediately prior to the Effective Time and held in the treasury of
         Tamarack shall automatically be canceled and extinguished and no
         payment shall be made with respect thereto.

                  (c) Each share of Common Stock, par value $0.01 per share, of
         Merger Sub issued and outstanding immediately prior to the Effective
         Time shall automatically be converted into and become one validly
         issued, fully paid and nonassessable share of Common Stock, no par
         value per share, of the Surviving Corporation. Each stock certificate
         of Merger Sub evidencing ownership of any such shares shall continue to
         evidence ownership of such shares of capital stock of the Surviving
         Corporation.

                  (d) The Exchange Ratio 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 Tamarack Common Stock), reorganization,
         recapitalization or other like change with respect to SuperShuttle
         Common Stock or Tamarack Common Stock occurring after the date hereof
         and prior to the Effective Time, but shall not be adjusted for the
         exercise or conversion of any outstanding SuperShuttle securities
         convertible into SuperShuttle Common Stock.

         1.6 No Fractional Shares. No fractional shares of SuperShuttle Common
Stock shall be issued. Fractional shares of such stock shall be rounded to the 
nearest whole share.





                                       3
<PAGE>   9
1.7 Exchange for Merger Consideration. At the Effective Time, each of the
Shareholders shall surrender the certificate or certificates representing shares
of Tamarack Common Stock to SuperShuttle. Promptly following surrender,
SuperShuttle shall issue the SuperShuttle Common Stock payable to the
Shareholders pursuant to Section 1.5. The certificates of Tamarack Common Stock
surrendered to SuperShuttle shall be duly endorsed and otherwise in proper form
for transfer as SuperShuttle may require. SuperShuttle shall not be obligated to
deliver the consideration to which any Shareholder is entitled as a result of
the Merger until such Shareholder surrenders his or her certificate or
certificates representing the shares of Tamarack Common Stock to be exchanged.
After the Effective Time, each outstanding certificate or certificates that
represented shares of Tamarack Common Stock as of the Effective Time shall be
deemed for all corporate purposes to evidence only the right of the holder
thereof to receive such person's share of the consideration calculated pursuant
to Section 1.5 in exchange therefor. No interest shall be paid or accrued on any
consideration payable upon the surrender of the certificates.

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

         1.9      Dissenter's Rights.  Subject to Section  7.2(e):

                  (a) Any shares of capital stock of Tamarack held by a holder
         who has exercised dissenters' rights for such shares in accordance with
         Chapter 13 of the California Corporations Code and who, as of the
         Effective Time, has not effectively withdrawn or lost (through failure
         to perfect or otherwise) such dissenters' rights ("Dissenting Shares"),
         shall not be converted into or represent a right to receive
         SuperShuttle Common Stock pursuant to Section  1.5 but the holder
         thereof shall only be entitled to such rights as are granted by
         applicable corporate law.

                  (b) Notwithstanding the provisions of subsection (a), if any
         holder of Dissenting Shares shall effectively withdraw or lose his
         dissenters' rights, then, as of the later of the Effective Time or the
         occurrence of such event, such holder's shares shall automatically be
         converted into and represent only the right to receive the Merger
         consideration set forth in Section  1.5, without interest thereon, upon
         surrender of the certificate or certificates representing such
         Dissenting Shares.

                  (c) Tamarack shall give SuperShuttle (i) prompt notice of any
         written demands received by Tamarack to require Tamarack to purchase
         shares of capital stock of Tamarack, withdrawals of such demands, and
         any other instruments served pursuant to Chapter 13 of the California
         Corporations Code and received by Tamarack and (ii) the opportunity to
         participate in all negotiations and proceedings with respect to such
         demands. Tamarack shall not, except with the prior written consent of
         SuperShuttle, voluntarily make any payment with respect to any such
         demands or offer to settle or settle any such demands.




                                       4
<PAGE>   10
         1.10 Lost, Stolen or Destroyed Certificates. In the event any
certificates representing shares of Tamarack 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
Sections 1.5 and 1.6; 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.

         1.11 Taking of Necessary Action; Further Action. SuperShuttle and
Merger Sub, on the one hand, and Tamarack 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
Merger) as may be necessary or appropriate in order to effectuate the Merger 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 and
to vest the Surviving Corporation with full possession of all the rights,
privileges, immunities and franchises of the Constituent Corporations, or fully
subject the Surviving Corporation to all liabilities and obligations of the
Constituent Corporations, the officers and directors of the Surviving
Corporation are fully authorized in the name of the Constituent Corporations or
otherwise to take, and shall take, all such lawful and necessary actions.

         1.12 Escrow. Concurrent with the filing of the Articles, officers'
certificates and Agreement of Merger as set forth in Section  1.3 above, the
parties shall deliver the stock certificates of SuperShuttle and Tamarack to be
exchanged to an escrow agent (the "Escrow Agent") to hold in escrow pending the
Closing (as defined in Section  1.13), subject to the terms of the Escrow
Agreement, a copy of which is attached hereto as Exhibit "F."

         1.13 Effective Date; Closing. The Effective Date of this Agreement
shall be March 31, 1998. The Closing of the transactions contemplated by this
Agreement shall occur upon the satisfaction of the conditions set forth in
Article 7 of this Agreement, all of which conditions shall be satisfied on or
before the Closing Date or such other date as required by the applicable
conditions, and the escrow is broken.

                                    ARTICLE 2

                 REPRESENTATIONS AND WARRANTIES OF SUPERSHUTTLE

                                 AND MERGER SUB

         SuperShuttle and Merger Sub hereby represent and warrant to Tamarack as
of the date hereof, and again at the Effective Time (subject to any changes
permitted or contemplated hereby), each of the following, except to the extent
set forth in the disclosure schedule that has been delivered to Tamarack
hereunder (the "SuperShuttle Disclosure Schedule"):

         2.1 Organization and Qualification. Each of SuperShuttle and Merger Sub
is a corporation duly organized, validly existing and in good standing under the
laws of the State of Delaware and the State of Arizona, respectively, and has
the requisite corporate power and


                                       5
<PAGE>   11
authority to own and operate its properties and to carry on its business as now
conducted in every jurisdiction where the failure to do so would have a material
adverse effect on its business, properties or ability to conduct the business
currently conducted by it. The copies of the Certificate of Incorporation,
Articles of Incorporation and Bylaws of SuperShuttle and Merger Sub previously
furnished to Tamarack are correct and complete and reflect all amendments
thereto.

         2.2 Authority Relative to This Agreement. Each of SuperShuttle and
Merger Sub has the requisite corporate power and authority to enter into this
Agreement and to carry out its obligations hereunder. The execution and delivery
of this Agreement by SuperShuttle and Merger Sub and the consummation by
SuperShuttle and Merger Sub of the transactions contemplated hereby have been
duly authorized by SuperShuttle and Merger Sub, and no other corporate
proceedings on the part of SuperShuttle or Merger Sub are necessary to authorize
this Agreement and such transactions. This Agreement has been duly executed and
delivered by SuperShuttle and Merger Sub and, assuming the due authorization,
execution and delivery by Tamarack, constitutes a valid and binding obligation
of each, enforceable in accordance with its terms, except as the enforceability
thereof may be limited by bankruptcy, insolvency, reorganization or other
similar laws relating to the enforcement of creditors' rights generally and by
general principles of equity. Except as set forth in the SuperShuttle Disclosure
Schedule, neither SuperShuttle nor Merger Sub is subject to, or obligated under,
any provision of (a) its Articles or Certificate of Incorporation or Bylaws, (b)
any material agreement, arrangement or understanding, (c) any material license,
franchise or permit, or (d) any law, regulation, order, judgment or decree,
which would be breached or violated, or in respect of which a right of
termination or acceleration would arise or any encumbrance on any of its or any
of its subsidiaries' assets would be created, by its execution, delivery and

outstanding, all of which shares are validly issued, fully paid and

         There are no obligations, contingent or otherwise, of SuperShuttle or
any of its subsidiaries to repurchase, redeem or otherwise acquire any shares of
SuperShuttle Common Stock or the capital stock of any subsidiary or to provide
funds to or make any investment (in the form of a loan, capital contribution or
otherwise) in any such subsidiary or any other entity. All of the outstanding
shares of capital stock of each of SuperShuttle's subsidiaries are duly
authorized, validly issued, fully paid and nonassessable and, except as

limitations in SuperShuttle's voting rights, charges or other encumbrances of
any nature whatsoever.

         2.4 Financial Statements. SuperShuttle has delivered a balance sheet
dated as of January 31, 1998, and other financial statements for the years ended
September 30, 1997 and September 30, 1996 to Tamarack (collectively, the

prepared in accordance with generally accepted accounting principles applied on
a consistent basis throughout the periods involved and present fairly the
consolidated financial position, results of operations, and cash flows of
SuperShuttle and its consolidated subsidiaries as of the dates and for the
periods indicated therein, subject, in the case of unaudited interim statements,
to normal year-end accounting adjustments and the absence of complete footnote
disclosure.

         2.5 Subsidiaries; Merger Sub. Except as set forth in the SuperShuttle
Disclosure Schedule, SuperShuttle does not have any subsidiaries and does not
otherwise own any stock, partnership interest, joint venture interest, or any
other security issued by or equity interest in any other corporation,
organization or entity. For purposes hereof, the term "subsidiary" means any
corporation of which securities having a majority of the ordinary voting power
in electing directors are owned directly or indirectly by a party. Merger Sub is
not subject to any liabilities, obligations or claims, whether absolute or
contingent, liquidated or unliquidated. Merger Sub was formed solely for the
purpose of consummating the transactions contemplated by this Agreement and has
not engaged in any business or other activities for any other purpose. Unless
the context requires otherwise, the term "SuperShuttle" shall hereafter refer to
SuperShuttle and/or its Subsidiaries.

or otherwise, whether due or to become due and regardless of when asserted),
except (a) obligations under contracts or commitments described in Section  2.6
of the SuperShuttle Disclosure Schedule; (b) liabilities reflected on the

         historical practice of SuperShuttle;

                  (c) discharged or satisfied any lien or encumbrance or paid

         SuperShuttle; or

                  (e) suffered any material theft, damage, destruction or loss

Disclosure Schedule, SuperShuttle (i) has obtained all applicable permits,
licenses and other authorizations (a list of which is set forth in the
SuperShuttle Disclosure Schedule) which are required under federal, state or
local laws relating to pollution or protection of the environment, including
laws relating to emissions, discharges, releases or threatened releases of
pollutants, contaminants, or hazardous or toxic materials or wastes into ambient

transport or handling of pollutants, contaminants or hazardous or toxic
materials or wastes by SuperShuttle (or its agents); (ii) is in compliance with
all terms and conditions of any required permits, licenses and authorizations,

demand letter issued, entered, promulgated or approved thereunder; (iii) is not
aware of nor has it received notice of 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, based on or resulting from SuperShuttle's (or any
agent's) manufacture, processing, distribution, use, treatment, storage,
disposal, transport, or handling, or the


                                       8

         2.12 Tax Matters. Except as set forth in the SuperShuttle Disclosure
Schedule, SuperShuttle has filed all federal, foreign, state, county and local
income, excise, property, sales and other tax returns which are required to be
filed by it for all periods prior to the Effective Time, and all such returns
are true and correct; all taxes due and payable by SuperShuttle (whether or not

SuperShuttle, the assessment of any additional taxes relating to SuperShuttle

has not received notice of any unresolved questions or claims concerning the tax
liability of SuperShuttle. SuperShuttle has not filed any consent agreement

Code) at any time within the applicable period specified in Section

<PAGE>   16
         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 SuperShuttle, in each case relating to its
         business (collectively, "Intellectual Property Rights"). The
         Intellectual Property Rights listed in the SuperShuttle Disclosure
         Schedule are all those used by SuperShuttle in connection with its
         business.

                  (b) No person has a right to receive a royalty or similar
         payment in respect of any Intellectual Property Rights. SuperShuttle
         has no licenses granted, sold or otherwise transferred by or to it or

         SuperShuttle has not received any notice of invalidity or infringement
         of any rights of others with respect to such Intellectual Property
         Rights. SuperShuttle has taken all reasonable and prudent steps to
         protect the Intellectual Property Rights from infringement by any other
         firm, corporation, association or person. SuperShuttle's use of the
         Intellectual Property Rights is not infringing upon or otherwise
         violating the rights of any third party in or to such Intellectual
         Property Rights, nor has such infringement been alleged by any third
         party. All of the Intellectual Property Rights are valid and
         enforceable rights of SuperShuttle and will not cease to be valid and
         in full force and effect by reason of the execution, delivery and
         performance of this Agreement or the consummation of the transactions
         contemplated by this Agreement.

         2.16 Litigation. Except as set forth in the SuperShuttle Disclosure

proceedings, orders or investigations pending or, to the knowledge of
SuperShuttle, threatened against SuperShuttle, 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, and there is no
basis known to SuperShuttle for any of the foregoing. Except as set forth in the
SuperShuttle Disclosure Schedule, SuperShuttle has not received any opinion or
legal advice to the effect that SuperShuttle is exposed from a legal standpoint
to any material liability. No governmental entity has at any time challenged or
questioned the legal right of SuperShuttle to offer or provide any of its
services in the present manner or style thereof.

         2.17 Brokers' Fees. SuperShuttle is not liable for any brokerage
commissions, finders' fees or similar compensation in connection with the
transactions contemplated by this Agreement.

         2.18 Compliance With Laws; Permits; Certain Operations. SuperShuttle
and its officers, directors, 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 SuperShuttle and to which SuperShuttle may be
subject, and no claims have been filed against SuperShuttle alleging a violation
of any such law or regulation, except as set forth in the SuperShuttle
Disclosure


                                       11
<PAGE>   17
Schedule. Without limiting the generality of the foregoing, SuperShuttle 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. SuperShuttle 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, governmental employee or any
other person in a position to assist or hinder SuperShuttle in connection with
any actual or proposed transaction. SuperShuttle holds all material permits,
licenses, certificates and other authorizations of foreign, federal, state and
local governmental agencies required for the conduct of its business.

         2.19 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, and there is
no fact which has not been disclosed to Tamarack that materially affects
adversely or could reasonably be anticipated to materially affect adversely the
assets, financial condition or operating results, customer, employee or supplier
relations, business condition or prospects, or financing arrangements of
SuperShuttle.

                   REPRESENTATIONS AND WARRANTIES OF TAMARACK

                              AND THE SHAREHOLDERS

         Tamarack and the Shareholders hereby represent and warrant to
SuperShuttle and Merger Sub as of the date hereof, and again at the Effective
Time (subject to any changes permitted or contemplated hereby), each of the
following, all of which are made jointly and severally by Tamarack and the
Shareholders who agree to be bound to and liable for the representations and
warranties set forth below and all other obligations of Tamarack under this
Agreement. Each of the following representations and warranties are qualified to
the extent set forth in the disclosure schedule that has been delivered to
SuperShuttle simultaneously with the execution and delivery of this Agreement
(the "Tamarack Disclosure Schedule"). The Tamarack Disclosure Schedule describes
exceptions to each applicable representation below by section numbers
corresponding to the section number of the applicable qualified representation.

         3.1 Organization and Qualification. Tamarack is a corporation duly
organized, validly existing and in good standing under the laws of the State of
California, and has the requisite corporate power and authority to own and
operate its properties and to carry on its business as now conducted in every
jurisdiction where the failure to do so would have a material adverse effect on
its business, properties or ability to conduct the business currently conducted
by it. The copies of the Articles of Incorporation and Bylaws of Tamarack
previously furnished to SuperShuttle are correct and complete and reflect all
amendments thereto.

         3.2 Authority Relative to This Agreement. Tamarack has the requisite
corporate power and authority to enter into this Agreement and to carry out its
obligations hereunder. The execution and delivery of this Agreement by Tamarack
and the consummation by Tamarack of the transactions contemplated hereby have
been duly authorized by Tamarack, and no other corporate proceedings on the part
of Tamarack are necessary to authorize this Agreement and


                                       12
<PAGE>   18
such transactions (other than the approval of the Shareholders). This Agreement
has been duly executed and delivered by Tamarack and, assuming the due
authorization and delivery thereof by SuperShuttle and Merger Sub, constitutes a
valid and binding obligation of Tamarack, enforceable in accordance with its
terms, except as the enforceability thereof may be limited by bankruptcy,
insolvency, reorganization or other similar laws relating to the enforcement of
creditors' rights generally and by general principles of equity. Except as set
forth in the Tamarack Disclosure Schedule, Tamarack is not subject to, or
obligated under, any provision of (a) its Articles of Incorporation or Bylaws,
(b) any material agreement, arrangement or understanding, (c) any material
license, franchise or permit, or (d) any law, regulation, order, judgment or
decree, which would be breached or violated, or in respect of which a right of
termination or acceleration would arise or any encumbrance on any of its or its
subsidiaries' assets would be created, by Tamarack's execution, delivery and
performance of this Agreement and the consummation by it of the transactions
contemplated hereby. Except for such filings to be made pursuant to the Merger
Statutes in order to effect the Merger, no authorization, consent or approval
of, or filing with, any public body, court or authority is necessary on the part
of Tamarack for the consummation by Tamarack of the transactions contemplated by
this Agreement.

         3.3 Capitalization. The authorized equity capitalization of Tamarack
consists of 100,000 shares of Common Stock. As of the date hereof, 5,000 shares
of Common Stock are issued and outstanding, all of which shares are validly
issued, fully paid and nonassessable. All of the issued and outstanding shares
of Common Stock of Tamarack are owned by the Shareholders. Except as set forth
in Section  3.3 of the Tamarack Disclosure Schedule, there are no options,
warrants, conversion privileges or other rights, agreements, arrangements or
commitments obligating Tamarack to issue or sell any shares of capital stock or
securities or obligations of any kind convertible into or exchangeable for any
shares of capital stock thereof or of any other corporation, nor are there any
stock appreciation, phantom stock or similar rights outstanding based upon the
book value or any other attribute of Tamarack. No holders of outstanding shares
of Tamarack Common Stock are entitled to any preemptive or other similar rights.
There are no obligations, contingent or otherwise, of Tamarack to repurchase,
redeem or otherwise acquire any shares of Tamarack or to provide funds to or
make any investment (in the form of a loan, capital contribution or otherwise)
in any entity other than guarantees of bank obligations of subsidiaries entered
into in the ordinary course of business. Upon consummation of the Merger,
SuperShuttle will own, directly or indirectly, the entire equity interest in
Tamarack, and there will be no options, warrants, conversion privileges or other
rights, agreements, arrangements or commitments obligating Tamarack to issue or
sell any shares of capital stock of Tamarack or any other corporation.

         3.4 Financial Statements. The consolidated financial statements of
Tamarack for the fiscal years ended December 31, 1995, 1996 and 1997, and for
the interim period ended February 28, 1998, (the "Tamarack Financial
Statements") have been delivered to SuperShuttle and were prepared in accordance
with generally accepted accounting principles applied on a consistent basis
throughout the periods involved and present fairly and accurately the
consolidated financial position, results of operations, and cash flows of
Tamarack as of the dates and for the periods indicated therein, subject, in the
case of unaudited interim statements, to normal year-end accounting adjustments.

                  (a) Tamarack owns good and marketable title to the properties
         and assets reflected on the December 31, 1997 Tamarack Balance Sheet or
         acquired since the date thereof, free and clear of all liens and
         encumbrances, except for (A) liens for current taxes not yet due and

         Schedule, (C) the properties subject to the leases set forth in Section
         3.9(a) of the Tamarack Disclosure Schedule, and (D) assets disposed of
         since December 31, 1997, in the ordinary course of business.

                  (b) (i) Tamarack does not own any real estate; (ii) the
         properties subject to the real property leases described in Section

         Tamarack's business, to public roads and to all utilities, including
         electricity, sanitary and storm sewer, potable water, natural gas and

                  (c) The real property leases described in Section  3.9(c) of
         the Tamarack Disclosure Schedule are in full force and effect, and

         SuperShuttle complete and accurate copies of each of the leases and
         none of such leases has been modified in any respect, except to the
         extent that such modifications are disclosed by the copies delivered to
         SuperShuttle. Tamarack is not in default, and no circumstances exist
         which could result in such default, under any of such leases, nor, to

         default.

         of machinery and equipment used in the business of Tamarack is included
         as Section 3.9(d) of the Tamarack Disclosure Schedule. Tamarack owns or
         leases under valid leases, all buildings, machinery, equipment and
         other tangible assets necessary for the conduct of its business.
         Tamarack has delivered to SuperShuttle complete and accurate copies of
         all equipment leases and such leases are listed in the Tamarack
         Disclosure Schedule. None of such equipment leases has been modified in
         any respect, except to the extent that such modifications are disclosed
         by the copies delivered to SuperShuttle. Tamarack is not in default,
         and no circumstances exist which could result in such default, under
         any of such equipment leases, nor, to the knowledge of Tamarack, is any
         other party to any of such equipment leases in default.

                  (e) Tamarack is not in any material respect in violation of
         any applicable zoning ordinance or other law, regulation or requirement
         relating to the operation of any properties used in the operation of
         its business, and Tamarack has not received any notice of any such
         violation, or of the existence of any condemnation proceeding with
         respect to any properties owned or leased by Tamarack.

of any required permits, licenses and authorizations, and with all other
limitations, restrictions, conditions, standards, prohibitions, requirements,
obligations, schedules and timetables contained in such laws or in any
regulation, code, plan, order, decree, judgment, notice or demand letter issued,
entered, promulgated or approved thereunder; (iii) is not aware of nor has it
received notice of any event, condition, circumstance, activity, practice,
incident, action or plan which is reasonably likely to interfere with or prevent

statutory liability, or otherwise form the basis of any claim, action, suit or
proceeding, based on or resulting from Tamarack's (or any agent's) manufacture,
processing, distribution, use, treatment, storage, disposal, transport, or

reserves set forth on the books and records of Tamarack or as disclosed in the
Tamarack Disclosure Schedule. All such accounts receivable of Tamarack arose in
the ordinary course of business and are carried at values determined in
accordance with generally accepted accounting principles consistently applied.

         3.12 Tax Matters. Except as set forth in the Tamarack Disclosure
Schedule, Tamarack has filed all federal, foreign, state, county and local

filed by it for all periods prior to the Effective Time, and all such returns
are true and correct; all taxes due and payable by Tamarack (whether or not
shown on any tax return) for all periods prior to the Effective Time have been
paid; Tamarack's reserves and provisions for taxes on the balance sheets
included in the Tamarack Financial Statements are sufficient for all accrued and
unpaid taxes as of the dates of such balance sheets; Tamarack 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; Tamarack 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; to the best knowledge of Tamarack, the
assessment of any additional taxes relating to Tamarack for periods for which
returns have been filed is not expected; and Tamarack has not received notice of
any unresolved questions or claims concerning the tax liability of Tamarack.
Tamarack has not filed any consent agreement under Section  341(f) of

Regulation Section 1.1502-6 (or any similar provision of state, local or foreign
law) as a transferee or successor by contract or otherwise. Tamarack is not a
party to a tax sharing or allocation agreement nor does Tamarack owe any amount
under any such agreement. Tamarack 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. Tamarack 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

commitment, judgment, injunction, order or decree to which Tamarack is a party

         3.15 Intellectual Property Rights.

                  (a) The Tamarack Disclosure Schedule lists all of Tamarack'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 Tamarack 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 Tamarack, in each case relating to its business
         (collectively, "Intellectual Property Rights"). The Intellectual
         Property Rights listed in the Tamarack Disclosure Schedule are all
         those used by Tamarack in connection with its business.

                  (b) No person has a right to receive a royalty or similar

         of the Intellectual Property Rights, except as set forth in the
         Tamarack Disclosure Schedule.

                  (c) Tamarack owns and has the sole right to use each of the
         Intellectual Property Rights. None of the Intellectual Property Rights
         is involved in any pending or threatened litigation. Tamarack has not
         received any notice of invalidity or infringement of any rights of
         others with respect to such Intellectual Property Rights. Tamarack has
         taken all reasonable and prudent steps to protect the Intellectual
         Property Rights from infringement by any other firm, corporation,
         association or person. Tamarack's use of the Intellectual Property
         Rights is not infringing upon or otherwise violating the rights of any
         third party in or to such Intellectual Property Rights, nor has such
         infringement been alleged by any third party. All of the Intellectual
         Property Rights are valid and enforceable rights of Tamarack and will
         not cease to be valid and in full force and effect



                                       19

pending or, to the knowledge of Tamarack, threatened against Tamarack, at law or

department, commission, board, bureau, agency or instrumentality, domestic or
foreign, and there is no basis known to Tamarack for any of the foregoing.
Except as set forth in the Tamarack Disclosure Schedule, Tamarack has not
received any opinion or legal advice to the effect that Tamarack is exposed from

                  (a) With respect to the employees and former employees of
         Tamarack, except as set forth in the Tamarack Disclosure Schedule,
         Tamarack does not presently maintain, contribute to or have any
         liability (including current or potential multi-employer plan
         withdrawal liability under ERISA) under any (i) nonqualified deferred

         employee pension benefit plan, (iii) defined benefit pension plan or

         arrangement for present or future retirees or present or future
         terminated employees which is an "employee welfare benefit plan" as
         such term is defined in Section 3(1) of ERISA, except as required by
         Section 4980B of the Code or Section s 601 through 609 of ERISA, or
         (vi) any other employee welfare benefit plan.

                  (b) With respect to each of the employee benefit plans listed

<PAGE>   26
         determination letter received from the Internal Revenue Service, (iii)
         the latest actuarial valuation, (iv) the latest financial statement,
         (v) the last Form 5500 Annual Report, and (vi) all related trust
         agreements, insurance contracts or other funding agreements which
         implement such employee benefit plan. Neither Tamarack nor any of its
         directors, officers, employees or any other "fiduciary," as such term
         is defined in Section  3(21) of ERISA, has any liability for failure to
         comply with ERISA or the Code for any action or failure to act in
         connection with the administration or investment of such plans.

                  (c) With respect to each plan listed in the Tamarack
         Disclosure Schedule: (i) Tamarack has performed in all material
         respects all obligations required to be performed by it under each such
         plan and each such plan has been established and maintained in all
         material respects in accordance with its terms and in compliance with
         all applicable laws, statutes, rules, and regulations, including but
         not limited to the Code and ERISA; (ii) there are no actions, suits or
         claims pending or, to the knowledge of Tamarack, threatened (other than
         routine claims for benefits) against any such plan; (iii) each such
         plan can be amended or terminated after the Effective Time in
         accordance with its terms, without liability to Tamarack; and (iv)
         there are no inquiries or proceedings pending or, to the knowledge of
         Tamarack, threatened by the Internal Revenue Service or the Department

                  (d) With respect to the insurance contracts or funding
         agreements which implement any of the employee benefit plans listed in
         the Tamarack Disclosure Schedule, such insurance contracts or funding
         agreements are fully insured or the reserves under such contracts are
         sufficient to pay claims incurred.

                  (e) Each plan listed in the Tamarack Disclosure Schedule that
         is intended to be qualified under Section  401(a) of the Code has been
         determined by the Internal Revenue Service to so qualify and each trust
         created thereunder has been determined by the Internal Revenue Service
         to be exempt from tax under Section  501(a) of the Code and, to the
         knowledge of Tamarack, nothing has occurred since the date of the most
         recent determination that would be reasonably likely to cause any such
         plan or trust to fail to qualify under Section  401(a) of the Code.

         3.20 Insurance. The Tamarack Disclosure Schedule lists and briefly
describes each insurance policy and fidelity bond currently maintained by
Tamarack as well as each such policy and bond maintained by it for the five
years prior to the date of this Agreement, with respect to its properties,
assets, employees and officers and directors and sets forth the date of
expiration of each insurance policy. All insurance policies listed as currently
maintained are in full force and effect and Tamarack 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 Tamarack 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. Tamarack has no knowledge of any
threatened termination of, or material premium increase with respect to, any
such policies. To its knowledge, the insurance coverage of Tamarack is customary
for corporations of similar size engaged in similar lines of businesses.

         3.21 Insider Transactions. Except as set forth herein or in the
Tamarack Disclosure Schedule, no officer, director or shareholder of Tamarack 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 Tamarack or any interest in any property, real, personal
or mixed, tangible or intangible, used in or pertaining to the business of
Tamarack nor has had any such agreement or interest for the five years prior to
the date of this Agreement. 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. A list of all payments made to or for the benefit of any Insiders
during the prior five years is included within Section 3.21 of the Tamarack
Disclosure Schedule.

         3.22 Compliance With Laws; Permits; Certain Operations. Tamarack and
its officers, directors, 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 Tamarack and to which Tamarack may be subject, and
no claims have been filed against Tamarack alleging a violation of any such law
or regulation, except as set forth in the Tamarack Disclosure Schedule. Without
limiting the generality of the foregoing, Tamarack 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. Tamarack 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 Tamarack in connection with any actual or proposed
transaction. Tamarack holds all permits, licenses, 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
Tamarack 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, and there is
no fact which has not been disclosed to SuperShuttle that materially affects
adversely or could reasonably be anticipated to materially affect adversely the
assets, financial condition or operating results, customer, employee or supplier
relations, business condition or prospects, or financing arrangements of
Tamarack.

         3.24 Minute Books. The minute books of Tamarack shall be made available
to counsel for SuperShuttle and those delivered shall be the only minute books
of Tamarack 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 Tamarack.

            ADDITIONAL REPRESENTATIONS AND WARRANTIES OF SHAREHOLDERS

         Each of the Shareholders hereby represents and warrants to SuperShuttle
and Merger Sub as of the date hereof, and again at the Effective Time, with
respect to itself each of the following:

         4.1 Organization, Standing and Authority of Shareholders. The
Shareholder has all requisite power and authority to execute and deliver this
Agreement, to perform its obligations hereunder and to consummate the
transactions contemplated hereby.

         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, other laws affecting generally the enforcement of
         creditors' rights, or by public policy related to the availability of
         equitable remedies.

                  (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
Shareholder of this Agreement and the consummation by Shareholder of the
transactions contemplated hereby do not require Shareholder to obtain any
consent, approval or action of, or make any filing with or give any notice to,
any corporation, person or firm or any public, governmental or judicial
authority except: (a) such as have been duly obtained or made, as the case may
be, and are in full force and effect on the date hereof; and (b) those which the
failure to obtain would have no material adverse affect on the transactions
contemplated hereby.

         4.4 Brokers. All negotiations relative to this Agreement and the
transactions contemplated hereby have been carried out by Shareholder directly
with the other parties hereto, without the intervention of any person on behalf
of Shareholder in such manner as to give rise to any claim by any person against
the Company, Tamarack or Shareholders for a finder's fee, brokerage commission
or similar payment.



                                       23
<PAGE>   29
         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 the Securities Act of 1933 (the "Securities Act"), as
amended, 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.

         4.6      Shareholder Experience and Investment Representations.

                  (a) The Shareholder is able to bear the economic risk of an
         investment in the securities acquired by it pursuant to this Agreement
         and can afford to sustain a total loss on such investment.

                  (b) The Shareholder is an experienced and sophisticated
         investor and has such knowledge and experience in financial and
         business 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. The
         Shareholder represents and warrants that the nature and amount of the
         securities it is purchasing is consistent with its investment
         objectives, abilities and resources.

                  (c) The Shareholder, by reason of its business or financial
         experience and the business or financial experience of its professional
         advisors (who are unaffiliated with and who are not compensated by the
         Company or any affiliate or selling agent of the Company, directly or
         indirectly), has the capacity to protect its own interest in connection
         with the purchase of the securities. The Shareholder has consulted with
         counsel of its own choosing in making an informed decision with respect
         to the Merger consideration and the terms of this Agreement.

                  (d) The Shareholder is an "accredited investor" as defined in
         and for purposes of Rule 501 and Regulation D promulgated by the
         Securities and Exchange Commission ("SEC") under the Securities Act.

         its business or in the operation of its properties and of any
         governmental or third party complaints, investigations or hearings (or
         communications indicating that the same may be contemplated); and (iii)
         shall not take any action which would render, or which reasonably may
         be expected to render, any representation or warranty made by it in
         this Agreement untrue at, or at any time prior to, the Effective Time;

                  (c) Tamarack shall not, directly or indirectly, do or permit

         previously granted options) or (B) any of its assets, except in the
         ordinary course of business consistent with past practices; (iii)
         split, combine or reclassify any of its outstanding shares, or declare,

         stock, property or otherwise with respect to any shares of its capital
         stock; (iv) redeem, purchase or acquire or offer to acquire any shares
         of its capital stock; (v) acquire (by merger, exchange, consolidation,
         acquisition of stock or assets or otherwise) any corporation,
         partnership, joint venture or other business organization or division
         or material assets thereof or any interest therein; (vi) incur any
         indebtedness for borrowed money or issue any debt securities (other

         past practices); (vii) make any loans (except for advances to sales
         personnel in the ordinary course of business and consistent with past
         practice); (viii) enter into any Insider transactions; or (ix) enter
         into or propose to enter into, or modify or propose to modify, any

                                       25
<PAGE>   31
                  (d) Tamarack shall not, directly or indirectly, enter into or
         modify any contract, agreement or understanding, written or oral, that
         involves consideration or performance of Tamarack, as the case may be,

         in the ordinary course of business and consistent with past practice;

                  (e) Tamarack shall not enter into or modify any employment,
         severance or similar agreements or arrangements with, or grant any
         bonuses, salary increases, or severance or termination pay to, any
         officers, directors, employees or consultants other than in the
         ordinary course of business and consistent with past practice;

                  (f) Tamarack shall not adopt or amend in any material respect
         any bonus, profit sharing, compensation, stock option, pension,
         retirement, deferred compensation, employment or other benefit plan,
         trust, fund or group arrangement for the benefit or welfare of any
         officers, directors or employees; and

                  (g) Tamarack shall not allow its current insurance policies to
         be canceled or terminated or any of the coverage thereunder to lapse,
         unless simultaneous with such termination, cancellation or lapse,
         replacement policies providing coverage equal to or greater than the
         coverage under the canceled, terminated or lapsed policies for
         substantially similar premiums are in full force and effect.

         5.2 Conduct Subsequent to the Merger.

                  (a) SuperShuttle agrees and covenants to use its best efforts
         to consummate an initial public offering of SuperShuttle Common Stock
         within a reasonable period of time, which shall not exceed 130 days
         from the date of this Agreement. If SuperShuttle does not consummate an
         initial public offering of SuperShuttle Common Stock within such
         period, the Shareholders shall have the right to repurchase, at fair
         market value, all of the shares of Tamarack Common Stock transferred to
         SuperShuttle. Tamarack will be responsible for payment of its own and
         its Shareholders' fees and expenses in connection with the exercise of
         such repurchase right. Each of SuperShuttle and Tamarack agree that if
         the Shareholders exercise the repurchase right referenced above, the
         exchange of Tamarack's SuperShuttle Common Stock for Tamarack Common
         Stock will occur with no liability on the part of SuperShuttle as to
         the condition of Tamarack during the time SuperShuttle was in
         possession of the Tamarack Common Stock.

                  (b) Until the earlier of (a) an underwritten public offering
         by SuperShuttle of its common stock pursuant to an effective
         registration statement under the Securities Act, or (b) 60 days after
         July 31, 1998, SuperShuttle shall (i) not cause the Surviving
         Corporation to make any material changes in its business, operations,
         facilities or personnel unless such change is approved by the holders
         of a majority of the stock issued pursuant to Section  1.5(a), (ii)
         shall use its best efforts to preserve intact the business organization
         and goodwill of the Surviving Corporation, (iii) will not cause the
         Surviving Corporation to take any of the actions described in Section
         5.1(c) and (iv) shall devote reasonable financial and personnel
         resources to the Surviving Corporation.



                                       26
<PAGE>   32
                  (c) Each of SuperShuttle and Tamarack covenant and agree that
         SuperShuttle shall have the right (for thirty (30) days following the
         applicable target date) to repurchase, at fair market value, all of the
         SuperShuttle Common Stock to be transferred to Tamarack in connection
         with the Merger, if either of the conditions in Section  7.4 are not
         satisfied. SuperShuttle will be responsible for payment of its own fees
         and expenses in connection with the exercise of such repurchase right.

                  (d) The parties intend to effect the Merger as a tax-free
         reorganization. SuperShuttle undertakes to do all things reasonably
         necessary to effect the transaction in a tax-free manner as requested
         by Tamarack, provided such actions do not affect the underlying
         economics of the transaction for SuperShuttle. However, SuperShuttle
         shall not be responsible for any set of circumstances that affects the
         tax-free nature of the transaction.

                  (e) SuperShuttle agrees to undertake to remove the
         Shareholders as personal guarantors of any and all loans and leases of
         the Surviving Corporation and to replace the Shareholders as the
         guarantors of such obligations, provided that there has been no
         personal wrongdoing or misrepresentation on the part of the
         Shareholders in connection with such obligations. This assumption of
         personal guarantees will take effect upon the later of (a) an
         underwritten public offering by SuperShuttle of its common stock
         pursuant to an effective registration statement under the Securities
         Act or (b) 60 days after July 31, 1998. Unless and until such personal
         guarantees of Shareholders have been removed, SuperShuttle agrees to
         indemnify, defend and hold harmless the Shareholders from and against
         any and all claims, damages and expenses arising from or related to
         such personal guarantees.

                                    ARTICLE 6

                              ADDITIONAL AGREEMENTS

hereof, take all action necessary in accordance with California Law and its
Articles of Incorporation and Bylaws to convene a meeting of the Shareholders to
consider the Merger (the "Tamarack Shareholders Meeting") (or solicit the
written consent of the Shareholders to the Merger). Tamarack shall consult
SuperShuttle as to the date of the Tamarack Shareholders Meeting (or the date
written consents are expected to be requested) and shall not postpone or adjourn
(other than for the absence of a quorum) the Tamarack Shareholders Meeting
without the consent of SuperShuttle. Tamarack shall use its reasonable best
efforts to secure the vote (or consent) of the Shareholders required by
California Law to effect the Merger. Tamarack has received irrevocable consents
from the Shareholders executing this Agreement to approve the Merger and by
their signatures below the Shareholders agree to all acts and things necessary
to effect the Merger on the terms hereof.

         6.4 Notification of Certain Matters. SuperShuttle and Tamarack shall
give prompt notice to each other of (i) the occurrence or failure to occur of

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.

         SuperShuttle and Merger Sub shall have the opportunity to make a
         complete review of the books, records, business and affairs of
         Tamarack. Such review may be conducted at any and all reasonable times
         by such persons as SuperShuttle designates. To facilitate such review,
         Tamarack shall provide to SuperShuttle and its agents complete access
         to all of its records and documents, shall provide the other party 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, Merger Sub and Tamarack agrees that

         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 Tamarack on March 2, 1998.

         6.6 Consents; Approvals. SuperShuttle, Merger Sub and Tamarack shall

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

and 7.3(a).

         6.8 Non-Solicitation of Employees. For a period of one year from the

SuperShuttle's Board of Directors.

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

                  (a) that until the later of a period of three years following
         the consummation of the Merger transactions or following the
         termination of the employment agreement referenced in Section  7.1(d),
         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 Tamarack, SuperShuttle or Merger Sub, 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 other information of a proprietary or
         confidential character;

                  (b) that until the later of a period of three years following
         the consummation of the Merger transactions or following the
         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 Tamarack, SuperShuttle or any affiliate
         of either of them as such business is presently conducted in either
         Orange, Los Angeles, Riverside or San Diego counties or any county
         contiguous



                                       29
<PAGE>   35
         thereto (the "Applicable Counties"). Not limiting the generality of the
         foregoing, the business of Tamarack 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, but excluding the
         operation of taxis;

                  (c) that until the later of a period of three years following
         the consummation of the Merger transactions or following the
         termination of the employment agreement referenced in Section  7.1(d),
         the Shareholder shall not solicit or negotiate any contract or
         agreement that constitutes or would constitute engaging in competition
         with the business of Tamarack or SuperShuttle in the Applicable
         Counties; and

                  (d) each of the Shareholders by execution of this Agreement
         grants to Tamarack a fully paid irrevocable license to use any and all
         rights and interests in the business concept employed by Tamarack 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 at any place at
         which SuperShuttle or any of its affiliates conduct business. To the
         extent that any business concept employed by a Shareholder would
         involve the conduct of any form of shared ride transportation business,
         the license granted to SuperShuttle shall be deemed exclusive to
         SuperShuttle.

         In connection with the limitation protections afforded to SuperShuttle
by the covenants set forth above in this Section  6.10, the Shareholders
recognize that SuperShuttle has a need for the covenants and that need is based
upon the following:

                  (i) SuperShuttle's expenditure of substantial time, money and
         effort in developing its business and the valuable list of customers
         and information about the requirements and needs associated with the
         business, including the business of Tamarack being acquired through the
         Merger;

                  (ii) Shareholder through the course of his or her relationship
         with Tamarack has been or may have been entrusted with or exposed to
         certain trade secrets and other confidential information, the
         confidentiality of which is critical to the ongoing business of
         SuperShuttle, including the business to be acquired through the Merger
         of Tamarack into Merger Sub;

                  (iii) SuperShuttle provides and will provide services
         throughout the Applicable Counties; and

                  (iv) SuperShuttle would suffer great loss and irreparable harm
         if the Shareholders were to violate the foregoing covenants.

         The Shareholders hereby specifically acknowledge and agree that the
temporal, geographical and other restrictions contained in this Section 6.10 are
reasonable and necessary to protect the business and prospects of Tamarack and
SuperShuttle and that the enforcement of


                                       30
<PAGE>   36
the provisions of this Section 6.10 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 6.10 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 6.10 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  6.10 are held to be invalid or
unenforceable as against public policy, the remaining provisions of this
Agreement shall not be affected thereby.

         restraining, enjoining or otherwise prohibiting the Merger;

                  (d) by either SuperShuttle or Tamarack if the Merger shall not
         have been consummated on or before March 31, 1998, or such later date
         as may be mutually agreed upon by the parties;

                  (e) by SuperShuttle, if the conditions set forth in Section
         7.2 hereof shall have not been complied with or performed and such

Agreement as provided in Section 8.1, this Agreement shall become void and there
