                             SHAREHOLDERS AGREEMENT

     THIS SHAREHOLDERS AGREEMENT ("Agreement") is entered into effective as of
the 1st day of September, 1997, by and among SUPERSHUTTLE INTERNATIONAL, INC.,
a Delaware corporation (hereinafter referred to as "SSI"), SHUTTLE EXPRESS,
INC., a Maryland corporation (hereinafter referred to as the "Company"), and
YELLOW HOLDING, INC., a Maryland corporation (hereinafter referred to as
"Yellow"). SSI and Yellow are herein sometimes referred to collectively as the
"Shareholders", and each singly as "Shareholder".

     WHEREAS, the Shareholders aggregately own all of the capital stock of the
Company (hereinafter referred to as "Shares"), and they and the Company wish to
restrict stock ownership of the Company to parties with whom they mutually
choose to deal to assure the continued ease of administration of the Company's
business.

     WHEREAS, the parties desire to promote their individual interests and the
interests of the Company by imposing certain restrictions and obligations on
the Shareholders, the Company, and the Shares.

     NOW, THEREFORE, in consideration of the foregoing premises and mutual
covenants hereinafter contained, and for other good and lawful consideration,
the receipt and sufficiency of which are hereby acknowledged, the parties
agree as follows:


                                   ARTICLE 1
                         RESTRICTION ON SALE OF SHARES

     1.1 Endorsement of Stock. Upon the execution of this Agreement, the
certificates representing the Shares shall be surrendered to the Secretary of
the Company and endorsed as follows:

     THE SHARES OF STOCK REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A
     SHAREHOLDERS AGREEMENT TO WHICH THE COMPANY IS A PARTY, AND NONE OF SUCH
     SHARES, OR ANY INTEREST THEREIN, SHALL BE TRANSFERRED, PLEDGED, ENCUMBERED
     OR OTHERWISE DISPOSED OF EXCEPT AS PROVIDED IN SUCH AGREEMENT. A COPY OF
     THE AGREEMENT IS ON FILE IN THE OFFICE OF THE COMPANY AND WILL BE MADE
     AVAILABLE FOR INSPECTION TO ANY PROPERLY INTERESTED PERSON WITHOUT CHARGE
     WITHIN FIVE (5) WORKING DAYS AFTER THE COMPANY'S RECEIPT OF A WRITTEN
     REQUEST.


                                       1
<PAGE>   2
     A copy of this Agreement, together with any amendments thereto shall remain
on file with the Secretary of the Company and shall be available for inspection
to any properly interested person without charge within five (5) working days
after the Company's receipt of a written request therefor.

     Subject to the terms of this Agreement, the Shareholders shall be entitled
to exercise all rights of ownership in the Shares.

     No shares of any class of stock of the Company, other than the Shares, are
presently issued and outstanding. If the Company issues additional shares, the
Company shall cause all shares so issued to bear the above endorsement, and to
be subject to all the terms and conditions of this Agreement, and such shares
shall for all purposes be deemed "Shares" hereunder. Each person receiving such
issued shares shall automatically be deemed a "Shareholder" hereunder, and in
furtherance thereof, each such person shall execute and deliver to the parties
hereto an agreement in writing to be bound by this Agreement.

     1.2  Restrictions on Transfer or Encumbrance.  Except as otherwise set
forth in this Agreement, no Shareholder shall, without the prior written consent
of all other Shareholders, transfer, or permit the transfer of, all or any part
of the Shares, or any interest therein, whether legal or beneficial, now owned
or hereafter acquired by such Shareholder. Any attempted transaction not in
compliance with this Section 1.2 shall be void. As used in this Agreement, the
verb "transfer," in whatever form, number or tense, shall mean, as the case may
be, encumber or in any manner use as collateral, to transfer, or to sell or
otherwise to dispose of, or suffer disposition or encumbrance, voluntarily or
involuntarily.
                                        
                                   ARTICLE II
                    SPECIFIC OPTIONS BETWEEN SSI AND YELLOW

     2.1  Call and Put Options.  SSI shall have a call option and Yellow shall
have a put option on the shares of stock of the Company owned by Yellow as
follows. SSI may exercise its call option at any time after the date thereof
through 5:00 p.m., Baltimore Time, June 1, 1999. Yellow may exercise its put
option only for the period between January 1, 1999 through 5:00 p.m., Baltimore
Time, June 1, 1999. The purchase price for either SSI's call option or Yellow's
put option shall be equal to 4.5 times the product of one-half (1/2) of the
Earnings Before Income Taxes ("EBIT") of the Company for the 12-month period
ending the calendar month immediately preceding the exercise of the put or call
option, but in no event for a price of less than One Million Dollars
($1,000,000.00) The EBIT of the Company for the relevant period shall be
determined by the accountant regularly employed by the Company at the time of
the triggering event, or if for any reason that accountant is then unable or
unwilling to act, or if there be no such accountant, then any certified public
accountant acceptable to the parties may be retained by for this purpose.

     The payment of the purchase price in the event of the exercise of a put or
call option shall be paid, at the option of SSI, as follows:

                                       2
<PAGE>   3
     An initial payment in cash at the closing of such sale of twenty-five
     percent (25%) of said price, with the balance payable in equal monthly
     installments over a period of thirty-six (36) months. The balance shall be
     evidenced by a promissory note bearing interest at the prime rate of
     interest charged by the primary bank of the Company in effect at the time
     of the closing. Yellow shall retain a security interest in the shares
     transferred as security for performance of SSI's obligations under the
     promissory note, and SSI agrees to execute and deliver such instruments
     (including share certificates) and documents as shall be necessary to
     create and perfect such security interest.

     2.2 Rejection of Yellow's Put Option By SSI. The foregoing notwithstanding,
SSI may reject Yellow's exercise of its put option, in which event either party
may immediately market all but not less than all of the authorized, issued and
outstanding stock or assets of the Company, for a period of 12 months, to any
bona fide third party purchaser. Upon receipt of a bona fide offer from a third
party purchaser acceptable to the party obtaining the offer, the other party
shall not unreasonably withhold its consent to the sale of its stock (or
substantially all of the assets) of or in the Company to said third party
purchaser. The total consideration to be received for the sale of all of the
Company's outstanding stock or all of its assets shall be shared equally by SSI
and Yellow.

     In addition, if SSI rejects the put option of Yellow then SSI shall cause
one of the directors of the Company who had been appointed by SSI to resign and
such director shall be replaced by the President of Yellow. SSI agrees to vote
its shares in such manner as to elect the President of Yellow as the fifth
director of the Company.

                                  ARTICLE III
                           TRANSFERS TO THIRD PARTIES

     3.1 Offering Notice; Non-Cash Consideration, Involuntary Transfers. Each
Shareholder hereby covenants, during the term of this Agreement, not to
transfer, or permit the transfer of, any Shares, or any interest therein,
whether legal or beneficial, to any third party until June 2, 1999, and then
only after first offering to transfer the same to or for the benefit of the
Company or the Shareholders as provided in this Article.

     (a) The Offering Notice. Any Shareholder (the "Selling Shareholder") having
received a bona fide offer from a third party and desiring to accept the offer,
or desiring to transfer any Shares to a third party, shall before accepting the
offer or proposing the transfer submit the offer or proposal in writing to each
of the other Shareholders (individually called "Optionee" and collectively
called "Optionees") and to the Company. The offer or proposal (the "Offering
Notice") shall identify the number of Shares and the interest therein that the
Selling Shareholder proposes to transfer (the "Offered Shares"), and shall set
forth the consideration for which the Offered Shares are proposed to be
transferred, the identity and the address of the third party (the "Proposed
Purchaser"), and all other terms and conditions of the proposed transaction.



                                       3


<PAGE>   4
     (b) Non-Cash Consideration. In the event the Offering Notice sets forth a
cash value for non-cash consideration, the Company and each Optionee shall have
ten (10) days, beginning with the day following receipt of the Offering Notice
by the Company and all Optionees, to make written, good faith objections to the
cash value specified for all or any part of the non-cash consideration. If the
Company or any Optionee objects to the cash value specified in the Offering
Notice for all or any part of the non-cash consideration, each objecting party
shall notify the Selling Shareholder, the Secretary of the Company, and the
other Optionees, as the case may be, in writing setting forth the cash value he
or it would assign to the disputed non-cash consideration and the reason(s)
therefor. If after ten (10) days, beginning with the day following receipt of
each such notice of objection by the Selling Shareholder, the Company and all
Optionees, there remains any objection to the cash value of any item of non-cash
consideration, the dispute over the cash value of such items shall be submitted
for arbitration pursuant to Section 4.4(o) hereof.

     (c) Involuntary Transfer. Any Shareholder who becomes aware that there is a
reasonable possibility Shares held by such Shareholder or any other Shareholder
may be transferred involuntarily in the reasonably foreseeable future shall
provide written notice to the Company and all other Shareholders describing in
reasonable detail the known circumstances concerning the possible transfer and
thereafter keep the Company and other Shareholders reasonably informed with
respect to the potential transfer. The date upon which an involuntary transfer
becomes effective shall be an "Involuntary Transfer Date" for purposes of this
Agreement. In the event of the occurrence of an Involuntary Transfer Date, any
person or entity who receives Shares as a result of the transfer that occurred
on the Involuntary Transfer Date shall be deemed to be a "Selling Shareholder"
for purposes of this Agreement, such Shares shall be deemed to be "Offered
Shares", and upon receipt of notice of such event, the Company shall send
written notice of such event identifying the number of Shares and the interest
therein held by the Selling Shareholder to all "Optionees," who shall consist
for this purpose of all Shareholders other than the Selling Shareholder and the
Shareholder, if any, from whom the Selling Shareholder acquired the Shares, and
such notice shall be deemed to be an "Offering Notice." Such Optionees and the
Company shall have the right to purchase such Shares pursuant to Section 3.2.

     3.2 Options to Purchase.

     (a) First Option. The Company shall have an option, continuing for thirty
(30) days, beginning with the day following receipt of the Offering Notice, to
elect to acquire all or any part of the Offered Shares on the terms set forth in
Section 3.4 hereof. If the Company elects to acquire all of the Offered Shares,
the Secretary of the Company shall, no later than the last day of the Company's
thirty (30) day option period, notify the Selling Shareholder and Optionees of
its decision in writing. (As used in this section and hereinafter in this
Agreement, the verb "acquire," in whatever form, number or tense, shall mean, as
the case may be, to take as security or as collateral, to accept a transfer, to
purchase, or otherwise to acquire.)

     (b) Second Option. If the Company elects not to exercise its option under
the preceding subsection or elects to acquire less than all the Offered Shares,
the Secretary of the Company shall,

                                       4
<PAGE>   5
no later than the last day of the Company's thirty (30) day option period,
notify the Selling Shareholder and Optionees of its decision in writing. Each
Optionee then shall have an option, continuing for a period of thirty (30)
days, beginning with the day following receipt of such notice by all Optionees,
to acquire, on the terms set forth in Section 3.4 hereof, all or any part of
the Offered Shares not acquired by the Company in the same ratio as the total
number of shares of the Company's capital stock owned by such Optionee bears to
the total number of shares of the capital stock of the Company then outstanding
and owned by all Optionees. Any Optionee desiring to acquire all or any part of
the Offered Shares not acquired by the Company shall deliver to the Secretary
of the Company within said thirty (30) day period a written election so to
acquire the Offered Shares or a specified portion thereof up to his
proportionate share.

     (c) Subsequent Options. If any Optionee does not elect to acquire his or
its proportionate share, the Secretary of the Company shall give written notice
thereof to all Optionees who elected to exercise their options (the "Exercising
Optionees"), no later than five (5) days following the last day of the option
period of the last Optionee to receive notice. Each Exercising Optionee shall
then have a further option, continuing for five (5) days, beginning with the
day following receipt of such notice by all Exercising Optionees, to elect to
acquire the still unsold Offered Shares in the same ratio that the total number
of shares of the Company's capital stock owned by him or it bears to the total
number of shares of the capital stock of the Company then outstanding and owned
by all Exercising Optionees. Any Exercising Optionee desiring to acquire all or
any part of the Offered Shares not acquired by the Company or by any Optionee
shall deliver a written election during said five (5) days period. Such notices
and options shall continue to be given in the same manner and for the same
periods until election(s) to acquire all of the Offered Shares are made, or
until no Exercising Optionee is willing to exercise his or its option to
acquire the remaining Offered Shares. Only an Exercising Optionee who shall
have fully exercised his or its last option under this Section 3.2(c) shall be
deemed to be an Exercising Optionee for purposes of notice and exercise of the
next subsequent option, if any, under this Section 3.2(c).

     3.3 Failure to Acquire All Offered Shares. To the extent the Company and
Optionees collectively do not elect pursuant to Section 3.2 to acquire all the
Offered Shares, then, if applicable, (i) the options granted hereunder to the
Company and Optionees shall, for purposes of the Offering Notice only, be
forfeited and the Selling Shareholder may complete the transaction with the
Proposed Purchaser, no later than the thirtieth (30th) day following the last
day of the last option period provided for herein, for the consideration per
Offered Share, for all, but not less than all the Offered Shares and upon all
the terms and conditions set forth in the Offering Notice, or (ii) with
respect to Offered Shares acquired upon an Involuntary Transfer Date, the
Company shall record the Selling Shareholder as the owner of record of such
Shares. The Offered Shares shall for all purposes remain subject to this
Agreement and the Proposed Purchaser, any person taking the Shares as
collateral pursuant to a pledge or other encumbrance, or any person holding
such Shares on account of the occurrence of an Involuntary Transfer Date
shall, upon completion of the transaction, immediately and automatically be
deemed a Shareholder hereunder and shall be bound by this Agreement. If
requested by the Company or any Shareholder, any such transferee shall, as a
condition to transfer, agree in writing to be bound by the terms of this
Agreement, including, in the case of a person taking

                                       5

<PAGE>   6
Shares as collateral, the requirement that he or it provide notice of default
and/or foreclosure to the Shareholders and the Company pursuant to Section 3.1.
A person taking the Shares as collateral pursuant to a pledge or other
encumbrance shall not have the right to exercise any option under Section 3.2 by
virtue of his so holding such shares as collateral or following foreclosure. If
the transaction with the Proposed Purchaser is not consummated by such
thirtieth (30th) day pursuant to the exact terms and conditions set forth in
the Offering Notice, then all the provisions of this Agreement shall be deemed
to apply again to all the Offered Shares.

     3.4  Election to Acquire Offered Shares. If the Company and/or the
Optionees elect to acquire Offered Shares pursuant to Section 3.2 hereof, the
Company and each Exercising Optionee shall be obligated to consummate his or
its election to acquire the Offered Shares pursuant to such election(s) no later
than the sixtieth (60th) day following the last exercise of an option, or the
sixtieth (60th) day following the determination of the Fair Market Value
pursuant to Section 3.5, if applicable (the "Closing").

     The price to acquire each Offered Share shall be the price, if any, set
forth in the Offering Notice (computed on the basis of the cash value of all
consideration as determined under Section 3.1(b)), or otherwise the Fair Market
Value as defined in Section 3.5 hereof or. With respect to a transfer that is
not an involuntary transfer, the price shall be paid upon the terms set forth in
the Offering Notice. With respect to involuntary transfers, the price may be
paid by the Company and/or each Exercising Optionee, as they, in their sole
discretion elect, as follows:

     (a)  cash in full, payable at the time of the Closing; or

     (b)  (except in the event the Selling Shareholder proposes only pledge,
          encumber or otherwise use the Offered Shares as collateral) an initial
          payment in cash at the closing of twenty-five percent (25%) of said
          price, with the balance payable in equal monthly installments over a
          period of thirty-six (36) months. The balance shall be evidenced by a
          promissory note bearing interest at the prime rate of interest charged
          by the primary bank of the Company in effect at the time of the
          closing. The Selling Shareholder shall retain a security interest in
          the Offered Shares subject to the exercised option as security for
          performance of the Company's and/or the Exercising Optionees
          obligations under the promissory note, and the Exercising Optionee
          and/or Company agree to execute and deliver such instruments
          (including share certificates) and documents as shall be necessary to
          create and perfect such security interest.

     When the Offering Notice pertains to an offer to lend funds to the Selling
Shareholder, secured by Shares of the Company, the Exercising Optionees sole
option shall be to elect to lend the funds on the terms set forth in the
Offering Notice.

     3.5  Fair Market Value.
<PAGE>   7
     (a) The Fair Market Value of a Share of the capital stock of the Company
shall mean that value which is determined pursuant to this Section 3.5. The
Fair Market Value may be mutually agreed upon by the selling and acquiring
parties of the shares of Stock. If the parties do not mutually agree upon the
Fair Market Value of a share of Stock within ten (10) days after delivery of a
written notice of exercise of a purchase right or obligation under this
Agreement, then the Fair Market Value of a share of Stock shall be equal to the
fair market value of such share as determined as of the date of such notice
pursuant to Section 3.5(b) below.

     (b) The net worth of the Company for purposes of this Agreements shall be
computed and determined as follows:

     (1) The net worth of the Company shall be equal to 4.5 times the Earnings
Before Income Taxes ("EBIT") of the Company for the 12-month period ending the
calendar month immediately preceding the date of the notice of exercise. The
EBIT of the Company for the relevant period shall be determined by the
accountant regularly employed by the Company at the time of the notice of
exercise, or if for any reason that accountant is then unable or unwilling to
act, or if there be no such accountant, then any certified public accountant
acceptable to the parties may be retained by for this purpose. Any dispute in
the selection of an accountant which continues for more than thirty (30) days
shall be resolved by arbitration pursuant to Section 4.4(o) of this Agreement.

     (3) The Fair Market Value of a share of stock of the Company shall be its
allocate portion of the Company's net worth so determined.
