                              EMPLOYMENT AGREEMENT

        AGREEMENT, dated this 20th day of November, 2000 by and between i3
MOBILE, INC., a Delaware corporation with principal executive offices at 181
Harbor Drive, Stamford, Connecticut 06902 ("i3 Mobile"), and JOHN A. LACK,
residing at 40 East 94th Street, New York, New York 10128 ("Lack").

                              W I T N E S S E T H :

        i3 Mobile is desirous of employing Lack as President and Chief Executive
Officer of i3 Mobile and Lack is desirous of serving i3 Mobile in such
capacities, all upon the terms and subject to the conditions hereinafter
provided.

        NOW, THEREFORE, in consideration of the mutual covenants and agreements
herein contained, the parties hereto, intending to be legally bound, agree as
follows:

1.      EMPLOYMENT.

        i3 Mobile agrees to employ Lack, and Lack agrees to be employed by i3
Mobile, upon the terms and subject to the conditions of this Agreement.

2.      TERM.

        The employment of Lack by i3 Mobile as provided in Section 1 will
commence on the date hereof and terminate on December 31, 2003, unless sooner
terminated as hereinafter provided (the "Term"), and shall automatically renew
from year to year thereafter unless either party gives at least ninety (90) days
prior written notice of termination.

3.      DUTIES; BEST EFFORTS; INDEMNIFICATION.

        Lack shall serve as President and Chief Executive Officer of i3 Mobile
and shall have the overall responsibility for, supervision of and control over
the day-to-day management of the business and operations of i3 Mobile, subject
to the general policy directions of the Board of Directors of i3 Mobile and the
Executive Committee of the Board. Lack shall also have such other powers and
duties as may be from time to time assigned to him by the Board of Directors or
Executive Committee, provided that the nature of Lack's powers and duties so
assigned shall not be inconsistent with Lack's positions and duties hereunder.

        Lack shall devote his full business time, attention and energies to the
business and affairs of i3 Mobile, shall use his best efforts to advance the
best interests of i3 Mobile and shall not during the Term be actively engaged in
any other business activity, whether or not such business activity is pursued
for gain, profit or other pecuniary advantage, that will interfere with the
performance by Lack of his duties hereunder or Lack's availability to perform
such duties or that will adversely affect, or negatively reflect upon, i3
Mobile.

        Subject to the provisions of i3 Mobile's Certificate of Incorporation
and Bylaws, each as amended from time to time, i3 Mobile shall indemnify Lack to
the fullest extent permitted by the

<PAGE>   2

General Corporation Law of the State of Delaware, as amended from time to time,
for all amounts (including, without limitation, judgments, fines, settlement
payments, expenses and attorney's fees) actually and reasonably incurred or paid
by Lack in connection with any action, suit, investigation or proceeding arising
out of relating to the performance by Lack of services for, or the acting by
Lack as a director, officer or employee of, i3 Mobile, or any other person or
enterprise at i3 Mobile's request if Lack acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of i3 Mobile,
and, with respect to any criminal action or proceeding, had no reasonable cause
to believe his conduct was unlawful. i3 Mobile shall use its best efforts to
maintain in full force and effect during the Term directors' and officers'
liability insurance policies providing full and adequate protection to Lack for
his capacities, provided that the Board of Directors of i3 Mobile shall have no
obligation to maintain such insurance if, in its opinion, coverage is available
only on unreasonable terms.

4.      PLACE OF PERFORMANCE.

        In connection with his employment by i3 Mobile, Lack shall be based at
the principal executive offices of i3 Mobile, which shall be in the Stamford,
Connecticut area. If i3 Mobile's principal executive offices are relocated more
than fifty (50) miles from their present location without the consent of Lack,
Lack shall have the right prior to such relocation to terminate his employment
hereunder pursuant to Section 6(c) hereof; provided, however, that if Lack does
not exercise such right and instead remains in the employ of i3 Mobile following
such relocation, i3 Mobile will promptly pay (or reimburse Lack for) all
reasonable moving and moving-related expenses incurred by Lack as a consequence
of a change of his principal residence in connection with any such relocation of
i3 Mobile's principal executive offices.

5.     COMPENSATION.

        (a)     Base Salary. i3 Mobile shall pay Lack a base salary (the "Base
Salary") at a rate of $300,000 per annum, payable in equal semimonthly
installments during the Term. The Board of Directors of i3 Mobile at least
annually will review the Base Salary and other compensation during the Term with
a view to increase thereof based upon then prevailing industry salary scales for
equivalently valued businesses for the chief executive officer position, Lack's
performance, the performance of i3 Mobile, inflation and other relevant factors.

        (b)     Out-of-Pocket Expenses. i3 Mobile shall promptly pay to Lack the
reasonable expenses incurred by him in the performance of his duties hereunder,
including, without limitation, those incurred in connection with business
related travel or entertainment, or, if such expenses are paid directly by Lack,
shall promptly reimburse him for such payment, provided that Lack properly
accounts therefor in accordance with i3 Mobile's policy.

        (c)     Participation in Benefit Plans. Lack shall be entitled to
participate in i3 Mobile's executive benefits plan that may include, but not be
limited to, a pension plan, profit sharing plan, stock option plan, stock
purchase plan or arrangement, group life insurance plan and health and accident
plan. Lack shall also be entitled to participate in any other employee benefit
plan or arrangement now available or made available in the future by i3 Mobile
to its executives and key management employees.

        (d)     Key-Man Life Insurance. i3 Mobile shall maintain a key-man life
insurance policy on the life of Lack in the aggregate amount of at least
$2,000,000, the proceeds of which shall be payable directly to i3 Mobile. Lack
agrees to submit to such medical examinations, to complete such

<PAGE>   3

documentation and otherwise to cooperate with i3 Mobile as may be required to
enable i3 Mobile to obtain and maintain such key-man life insurance.

        (e)     Vacation. Lack shall be entitled to paid vacation days in each
calendar year determined by i3 Mobile from time to time, but not less than four
(4) weeks in any calendar year, prorated in any calendar year during which Lack
is employed hereunder for less than an entire year in accordance with the number
of days in such year during which he is so employed. Lack shall also be entitled
to all paid holidays given by i3 Mobile to its executives and key management
employees.

        (f)     Incentive Compensation. i3 Mobile shall pay Lack on the date
hereof a signing bonus (the "Signing Bonus") in the amount of $50,000. i3 Mobile
shall also pay Lack a performance bonus (the "Performance Bonus"), in addition
to and separate from his Base Salary and other incentive compensation provided
for hereunder and subject to the achievement of certain mutually agreed
performance goals, in an amount up to fifty percent (50%) of his Base Salary.
Lack shall be entitled to the Performance Bonus on a prorata basis for partial
achievement of the performance goals.

        (g)     Dues and Subscriptions. i3 Mobile shall pay, or reimburse Lack
for, the cost of dues and subscriptions associated with business purposes in an
amount not to exceed $5,000 annually.

        (h)     Automobile. i3 Mobile shall provide Lack with exclusive use of
an automobile for business purposes during the Term and shall pay all costs in
connection therewith, including, without limitation, insurance, gas and repairs.
Such automobile shall be replaced periodically during the Term, and Lack shall
have the right, at the end of the Term or at any earlier termination thereof, to
purchase the automobile he is then using at its then depreciated book value.

        (i)     Stock Options. i3 Mobile shall grant to Lack stock options (the
"Options") under its 2000 Stock Incentive Plan to acquire an aggregate of
750,000 shares of i3 Mobile's Common Stock at an exercise price per share, (i)
equal to the closing market price of the Common Stock on the date hereof (the
"Market Price") for the first 250,000 shares, (ii) equal to the Market Price
plus $2.00 for the next 250,000 shares and (iii) equal to the Market Price plus
$4.00 for the last 250,000 shares. The Options shall vest on the basis of
125,000 shares on the six-month anniversary of the date hereof, 125,000 shares
on the twelve-month anniversary of the date hereof, 250,000 shares on the
twenty-four month anniversary of the date hereof and 250,000 shares on the
thirty-six month anniversary of the date hereof. The vesting schedule for the
Options shall be accelerated in the event of either of the events referred to in
Section 6(c)(iv) or (v) hereof unless Lack's employment continues without change
after the occurrence of either of such events.

6.      Termination.

        Lack's  employment hereunder shall be terminated upon Lack's death and
may be terminated as follows:

        (a)     By i3 Mobile for "Cause." A termination for Cause is a
termination evidenced by a resolution adopted by a vote of a majority of the
members of the Board finding that Lack has (i) willfully failed to comply with
any of the material terms of this Agreement, (ii) willfully and repeatedly
failed to perform his duties hereunder, (iii) engaged in gross misconduct
injurious to i3 Mobile or (iv) been convicted of, or pleaded nolo contendere to,
a felony or a crime of moral turpitude; provided, however, that Lack shall
receive thirty (30) days' advance written notice that the Board intends to meet
to consider Lack's termination for Cause and specifying the actions constituting
Cause, Lack shall not

<PAGE>   4

have cured the actions constituting Cause during such thirty (30) day period and
Lack shall be given a reasonable opportunity to be heard by the Board on the
issue prior to the Board's vote on the matter.

        (b)     By i3 Mobile due to Lack's "Disability." For purposes of this
Agreement, a termination for Disability shall occur (i) upon the thirtieth
(30th) day after the Board has provided a written termination notice to Lack
supported by a written statement from a reputable independent physician to the
effect that Lack shall have become so incapacitated as to be unable to resume,
within the ensuing twelve (12) months, his employment hereunder by reason of
physical or mental illness or injury or (ii) upon rendering of a written
termination notice by the Board after Lack has been unable to substantially
perform his duties hereunder for six (6) consecutive months or for nine (9)
months in any twelve (12) month period (exclusive of any vacation permitted
under Section 5(e) hereof) by reason of any physical or mental illness. For
purposes of this Section 6(b), Lack agrees to make himself available and to
cooperate in any reasonable examination by a reputable independent physician
retained by i3 Mobile.

        (c)     By Lack for "Good Reason." For purposes of this Agreement, Good
Reason shall mean (i) any circumstance that has the effect of significantly
reducing Lack's duties or authority provided for or contemplated herein (a
"Material Change"), (ii) a breach by i3 Mobile of its material obligations under
this Agreement (a "Material Breach"), (iii) the relocation of the principal
executive offices of i3 Mobile in excess of fifty (50) miles from their present
location not consented to by Lack, (iv) the acquisition by any person (as such
term is defined in Section 13(d) and 14(d)(2) of the Securities Exchange Act of
1934, as amended), directly or indirectly, of securities of i3 Mobile
representing fifty percent (50%) or more of the combined voting power of i3
Mobile's then outstanding securities in a transaction to which Lack does not
consent or (v) the future disposition by i3 Mobile (whether direct or indirect,
by sale of assets or stock, merger, consolidation or otherwise) of all or
substantially all of its business and/or assets in a transaction to which Lack
does not consent; provided, however, that a Material Change or a Material Breach
shall constitute Good Reason only if Lack has notified the Board in writing of
the existence and particulars of such Material Change or Material Breach and the
Board has failed to remedy such Material Change or Material Breach within thirty
(30) days of such notice.

7.      COMPENSATION UPON TERMINATION.

        (a)     In the event of the termination of Lack's employment as a result
of Lack's death, i3 Mobile shall (i) pay to Lack's estate his Base Salary and
accrued Performance Bonus through the date of his death and (ii) for the longer
of (x) eighteen (18) months following his death or (y) the balance of the Term
(as if such termination had not occurred) provide continuation coverage to Lack
and the members of Lack's family under all major medical and other health,
accident, life or other disability plans and programs in which Lack and such
family members participated immediately prior to his death.

        (b)     In the event of the termination of Lack's employment by i3
Mobile for Cause or by Lack other than for Good Reason, i3 Mobile shall pay to
Lack his Base Salary and accrued Performance Bonus through the date of his
termination, and Lack shall have no further entitlement to any other
compensation or benefits from i3 Mobile.

        (c)     In the event of the termination of Lack's employment by i3
Mobile due to Lack's Disability, i3 Mobile shall pay to Lack his Base Salary and
accrued Performance Bonus through the date of his termination. In addition, for
eighteen (18) months following any such termination, i3 Mobile shall (i)
continue to pay Lack the Base Salary in effect at the time of such termination
less the amount, if any, then payable to Lack under any disability benefits of
i3 Mobile and (ii) provide Lack continuation coverage under all major medical
and other health, accident, life or other disability plans and programs in which
Lack participated immediately prior to such termination.

<PAGE>   5

        (d)     In the event that Lack's employment is terminated by i3 Mobile
other than (i) as a result of Lack's death or (ii) for reasons specified in
Section 6(a) or (b) or by Lack for Good Reason, i3 Mobile shall continue to pay
to Lack his Base Salary and Performance Bonus for the greater of (x) eighteen
(18) months following any such termination or (y) the balance of the Term (as if
such termination had not occurred) and provide Lack continuation coverage under
all major medical and other health, accident, life or other disability plans or
programs in which Lack participated immediately prior to such termination for
the same period. Notwithstanding the foregoing, the amounts otherwise payable to
Lack pursuant to this Section 7(d) shall be subject to reduction (but not below
zero) to the extent determined reasonably necessary by i3 Mobile to prevent any
payments or benefits to or for the benefit of Lack (whether pursuant to this
Agreement or any other plan, arrangement or agreement) from being treated as a
"parachute payment" under Section 280G of the Internal Revenue Code of 1986, as
amended.

        (e)     The continuation coverage under any major medical and other
health, accident, life or other disability plans and programs for the periods
provided in Section 7(a), 7(c) and 7(d) shall be provided (i) at the expense of
i3 Mobile and (ii) in satisfaction of i3 Mobile's obligation under Section 4980B
of the Internal Revenue Code (and any similar state law) with respect to the
period of time such benefits are continued hereunder.

        (f)     If Lack disputes the termination of his employment by i3 Mobile
pursuant to Section 6(a) or 6(b) herein and such dispute results in a final
determination to the effect that i3 Mobile did not have a proper basis for such
termination, i3 Mobile shall promptly pay to Lack all payments Lack would have
been entitled to receive had his employment hereunder had not been improperly
terminated; provided, however, that any payments or benefits under this Section
7(f) shall be reduced by the amount of any payments or benefits provided under
any other provision of Section 7 hereof.

        (g)     This Section 7 sets forth the only obligations of i3 Mobile with
respect to the termination of Lack's employment with i3 Mobile, and Lack
acknowledges that, upon the termination of his employment, he shall not be
entitled to any payments or benefits which are not explicitly provided herein.

8.      COVENANT REGARDING INVENTIONS AND COPYRIGHTS.

        Lack shall disclose promptly to i3 Mobile any and all inventions,
discoveries, improvements and patentable or copyrightable works initiated,
conceived or made by him, either alone or in conjunction with others, during the
Term and related to the business or activities of i3 Mobile and he assigns all
of his interest therein to i3 Mobile or its nominee; whenever requested to do so
by i3 Mobile, Lack shall execute any and all applications, assignments or other
instruments which i3 Mobile shall deem necessary to apply for and obtain letters
patent or copyrights of the United States or any foreign country, or otherwise
protect i3 Mobile's interest therein. These obligations shall continue beyond
the conclusion of the Term with respect to inventions, discoveries, improvements
or copyrightable works initiated, conceived or made by Lack during the Term and
shall be binding upon Lack's assigns, executors, administrators and other legal
representatives.

9.      PROTECTION OF CONFIDENTIAL INFORMATION.

        Lack acknowledges that he has been and will be provided with information
about, and his employment by i3 Mobile will, throughout the Term, bring him into
close contact with, many confidential affairs of i3 Mobile and its subsidiaries,
including proprietary information about costs,

<PAGE>   6

profits, markets, sales, products, key personnel, pricing policies, operational
methods, technical processes and other business affairs and methods, plans for
future developments and other information not readily available to the public,
all of which are highly confidential and proprietary and all of which were
developed by i3 Mobile at great effort and expense. Lack further acknowledges
that the services to be performed by him under this Agreement are of a special,
unique, unusual, extraordinary and intellectual character, that the business of
i3 Mobile will be conducted throughout the world (the "Territory"), that its
services will be marketed throughout the Territory, that i3 Mobile competes and
will compete in all of its business activities with other organizations which
are located in any part of the Territory and that the nature of the relationship
of Lack with i3 Mobile is such that Lack is capable of competing with i3 Mobile
from nearly any location in the Territory. In recognition of the foregoing, Lack
covenants and agrees during the Term and for a period of five (5) years
thereafter:

        (i)     That he will keep secret all confidential matters of i3 Mobile
and not disclose them to anyone outside of i3 Mobile, either during or after the
Term, except with i3 Mobile's prior written consent or, if during the Term, in
the performance of his duties hereunder, Lack makes a good faith determination
that it is the best interest of i3 Mobile and to disclose such matters;

        (ii)    That he will not make use of any such confidential matters for
his own purposes or the benefit of anyone other than i3 Mobile; and

        (iii)   That he will deliver promptly to i3 Mobile on termination of
this Agreement, or at any time i3 Mobile may so request, all confidential
memoranda, notes, records, reports and other confidential documents (and all
copies thereof) relating to the business of i3 Mobile, which he may then possess
or have under his control.

The foregoing shall not apply to information or confidential matters of i3
Mobile to the extent, but only to the extent, that such information: (i) is
already known to Lack free of any restriction at the time it is obtained from i3
Mobile; (ii) is subsequently learned by Lack from an independent third party
free of any restriction and without breach of this Agreement or any agreement
with such third party; (iii) becomes publicly available through no wrongful act
of Lack; or (iv) is independently developed by Lack without reference to any
confidential matters of i3 Mobile.

10.     RESTRICTION ON COMPETITION, INTERFERENCE AND SOLICITATION.

        In recognition of the considerations described in Section 9 hereof, Lack
covenants and agrees that, during the Term and for a period of one (1) year or
such longer period of time during which Lack is continuing to receive
compensation from i3 Mobile after such termination, Lack will not, directly or
indirectly, (A) enter into the employ of, or render any services to, any person,
firm or corporation engaged in any business directly competitive with the
business of i3 Mobile in any part of the Territory in which i3 Mobile is
actively engaged in business on the date of termination; (B) engage in any such
business for his own account; (C) become interested in any such business as an
individual, partner, shareholder, creditor, director, officer, principal, agent,
employee, trustee, consultant, advisor, franchisee or in any other relationship
or capacity; or (D) interfere with i3 Mobile's relationship with, or endeavor to
employ or entice away from i3 Mobile any person, firm, corporation, governmental
entity or other business organization who or which is or was an employee,
customer or supplier of, or maintained a business relationship with, i3 Mobile
at any time (whether before or during the Term), or which i3 Mobile has
solicited or prepared to solicit; provided, however, that the provisions of
clause (A) shall not be deemed to preclude Lack from engagement by a corporation
some of the activities of which are competitive with the business of i3 Mobile
if Lack's engagement does not relate directly to such competitive business, and
nothing contained in this Section 10 shall be deemed to prohibit Lack from

<PAGE>   7

acquiring or holding, solely for investment, publicly traded securities of any
corporation some of the activities of which are competitive with the business of
i3 Mobile so long as such securities do not, in the aggregate, constitute more
than five percent (5%) of any class or series of outstanding securities of such
corporation.

11.     SPECIFIC REMEDIES.

        For purposes of Sections 8, 9 and 10 of this Agreement, references to i3
Mobile shall include all current and future majority-owned subsidiaries of i3
Mobile and all current and future joint ventures in which i3 Mobile shall have a
significant ownership or operational interest. It is understood by Lack and i3
Mobile that the covenants contained in this Section 11 and in Sections 8, 9 and
10 hereof are essential elements of this Agreement and that, but for the
agreement of Lack to comply with such covenants, i3 Mobile would not have agreed
to enter into this Agreement. i3 Mobile and Lack have independently consulted
with their respective counsel and have been advised concerning the
reasonableness and propriety of such covenants with specific regard to the
nature of the business conducted by i3 Mobile and all interests of i3 Mobile.
Lack agrees that the covenants of Sections 8, 9 or 10 hereof are reasonable and
valid. If Lack commits a breach of any of the provisions of Sections 8, 9 or 10
hereof, such breach shall be deemed to be grounds for termination for Cause. In
addition, Lack acknowledges that i3 Mobile may have no adequate remedy at law if
he violates any of the terms hereof. Lack therefore understands and agrees that
i3 Mobile shall have (i) the right to have such provisions specifically enforced
by any court having equity jurisdiction, it being acknowledged and agreed that
any such breach will cause irreparable injury to i3 Mobile and that money
damages will not provide an adequate remedy to i3 Mobile, and (ii) the right to
require Lack to account for and pay over to i3 Mobile all compensation, profits,
monies, accruals, increments and other benefits (collectively "Benefits")
derived or received by Lack as a result of any transaction constituting a breach
of any of the provisions of Sections 8, 9 or 10 and Lack hereby agrees to
account for and pay over such Benefits to i3 Mobile.

12.     INDEPENDENCE, SEVERABILITY AND NON-EXCLUSIVITY.

        Each of the rights enumerated in Sections 8, 9 or 10 hereof and the
remedies enumerated in Section 11 hereof shall be independent of the others and
shall be in addition to and not in lieu of any other rights and remedies
available to i3 Mobile at law or in equity. If any of the covenants contained in
Sections 8, 9 or 10, or any part of any of them, is hereafter construed or
adjudicated to be invalid or unenforceable, the same shall not affect the
remainder of the covenant or covenants or right or remedies which shall be given
full effect without regard to the invalid portions. The parties intend to and do
hereby confer jurisdiction to enforce the covenants contained in Sections 8, 9
or 10 and the remedies enumerated in Section 11 upon the federal and state
courts of Connecticut sitting in Fairfield County. If any of the covenants
contained in Sections 8, 9 or 10 is held to be invalid or unenforceable because
of the duration of such provision or the area covered thereby, the parties agree
that the court making such determination shall be the power to reduce the
duration and/or area of such provision and in its reduced from said provision
shall then be enforceable. No such holding of invalidity or unenforceability in
one jurisdiction shall bar on in any way affect i3 Mobile's right to the relief
provided in Section 11 or otherwise in the courts of any other state or
jurisdiction within the geographical scope of such covenants as to breaches of
such covenants in such other respective states or jurisdictions, such covenants
being, for this purpose, severable into diverse and independent covenants.

13.     DISPUTES.

        If i3 Mobile or Lack shall dispute any termination of Lack's employment
hereunder or if a dispute concerning any payment hereunder shall exist:

        (a)     either party shall have the right (but not the obligation), in
addition to all other rights and remedies provided by law, to compel binding,
enforceable and non-appealable arbitration of the dispute in the City of New
York under the rules of the American Arbitration Association by giving written
notice of arbitration to the other party within thirty (30) days after notice of
such dispute has been received by the party to whom notice has been given; and

        (b)     if such dispute (whether or not submitted to arbitration
pursuant to Section 13(a) hereof) results in a determination that (i) i3 Mobile
did not have the right to terminate Lack's employment under the provisions of
this Agreement or (ii) the position taken by Lack concerning payments to Lack is
correct, i3 Mobile shall promptly pay, or if theretofore paid by Lack, shall
promptly reimburse Lack for, all costs and expenses (including reasonable
attorneys' fees) reasonably incurred by Lack in connection with such dispute.

14.     Successors; Binding Agreement.

        In the event of a future disposition by i3 Mobile (whether direct or
indirect), by sale of assets or stock, merger, consolidation or otherwise, of
all or substantially all of its business and/or assets, i3 Mobile will require
any successor to expressly assume and agree to perform this Agreement in the
same manner and to the same extent that i3 Mobile would be required to perform
if no such disposition had taken place.

        This Agreement and all rights of Lack hereunder shall inure to the
benefit of, and be enforceable by, Lack's personal or legal representatives,
executors, administrators, administrators cta, successors, heirs, distributees,
devisees and legatees. If Lack should die while any amount would still be
payable to him hereunder if he had continued to live, all such amounts, unless
otherwise provided herein, shall be paid in accordance with the terms of this
Agreement to Lack's estate.

15.     NOTICES.

        All notices, consents and other communications required or permitted to
be given by any party hereunder shall be in writing (including telecopy or other

                              EMPLOYMENT AGREEMENT

AGREEMENT, effective as of the 21st day of December, 2000 by and between i3
MOBILE, INC., a Delaware corporation with principal executive offices at 181
Harbor Drive, Stamford, Connecticut 06902 ("i3 Mobile"), and WES TRAGER,
residing at 108C Bayville Avenue, Bayville, NY 11709 ("Trager").

                              W I T N E S S E T H :

WHEREAS, i3 Mobile is desirous of employing Trager as Chief Technology Officer
of i3 Mobile and Trager is desirous of serving in such capacity for i3 Mobile,
all upon the terms and subject to the conditions hereinafter provided.

NOW, THEREFORE, in consideration of the mutual covenants and agreements herein
contained, the parties hereto, intending to be legally bound, agree as follows:

1.      Employment.

        i3 Mobile agrees to employ Trager, and Trager agrees to be employed by
i3 Mobile, upon the terms and subject to the conditions of this Agreement.

2.      Term.

        The employment of Trager by i3 Mobile as provided in Section 1 will be
for a period of two (2) years commencing on the date hereof, unless sooner
terminated as hereinafter provided (the "Term"), and shall automatically renew
from year to year thereafter unless either party gives at least ninety (90) days
prior written notice of termination.

3.      Duties; Best Efforts; Indemnification.

        Trager shall serve as Chief Technology Officer of i3 Mobile and shall
perform, subject to the policy directions of the President and Chief Executive
Officer and the Board of Directors of i3 Mobile, such duties as are customarily
performed by the Chief Technology Officer. Trager shall also have such other
powers and duties as may be from time to time prescribed by the President and
Chief Executive Officer or the Board of Directors of i3 Mobile, provided that
the nature of Trager's powers and duties so prescribed shall not be inconsistent
with Trager's position and duties hereunder.

        Trager shall devote his business time, attention and energies to the
business and affairs of i3 Mobile, shall use his best efforts to advance the
best interests of i3 Mobile and shall not, during the Term, be actively engaged
in any other business activity, whether or not such business activity is pursued
for gain, profit or other pecuniary advantage, that will interfere with the
performance by Trager of his duties hereunder or Trager's availability to
perform such duties or that will adversely affect, or negatively reflect upon,
i3 Mobile.

        Subject to the provisions of i3 Mobile's Certificate of Incorporation
and Bylaws, each as amended from time to time, i3 Mobile shall indemnify Trager
to the fullest extent permitted by the General Corporation Law of the State of
Delaware, as amended from time to time, for all amounts (including, without
limitation, judgments, fines, settlement payments, expenses and attorney's fees)
actually and reasonably incurred or paid by Trager on a when- and as-incurred
basis in connection with any action, suit, investigation or proceeding arising
out of or relating to the performance by Trager of services for, or the acting
by Trager as a director, officer, or employee of, i3 Mobile, or any other person
or enterprise at i3 Mobile's request if Trager acted in good faith and in a
manner he reasonably believed to be in or not opposed to the best interests of
i3 Mobile, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. i3 Mobile shall use its
best efforts to obtain and maintain in full force and effect during the Term
directors' and officers' liability insurance policies providing full and
adequate protection to Trager for his capacity, provided that the Board of
Directors of i3 Mobile shall have no obligation to purchase such insurance if,
in its opinion, coverage is available only on unreasonable terms. Trager agrees
that, if it is finally judicially determined or finally determined by an
arbitrator that he is not or was not entitled to any amounts paid on his behalf
or for which he has been

<PAGE>   2

reimbursed under this third paragraph of this Section 3 by virtue of having
failed to have met the standards set forth in the first sentence of this third
paragraph of this section 3, Trager shall promptly reimburse i3 Mobile for such
amounts.

4.      Place of Performance.

        In connection with his employment by i3 Mobile, Trager shall be based at
the principal executive offices of i3 Mobile which shall be in the New York
Metropolitan area.

5.      Compensation.

    (a) Base Salary. i3 Mobile shall pay Trager a base salary (the "Base
Salary") at a rate of not less than $200,000 per annum, payable in equal
semi-monthly installments during the Term. The President and Chief Executive
Officer of i3 Mobile at least annually will review the Base Salary and other
compensation during the Term with a view to increase thereof based upon then
prevailing industry salary scales for equivalently valued businesses for the
Chief Technology Officer position, Trager's performance, the performance of i3
Mobile, inflation and other relevant factors.

    (b) Out-of-Pocket Expenses. i3 Mobile shall promptly pay to Trager the
reasonable expenses incurred by him in the performance of his duties hereunder,
including, without limitation, those incurred in connection with business
related travel or entertainment, or, if such expenses are paid directly by
Trager, shall promptly reimburse him for such payment, provided that Trager
properly accounts therefor in accordance with i3 Mobile's policy. i3 Mobile
shall provide Trager with corporate credit and phone cards to be used with
respect to the foregoing expenses.

    (c) Participation in Benefit Plans. Trager shall be eligible to participate
in the current i3 Mobile health, accident, life and disability insurance,
pension, profit sharing, stock option, stock purchase plans or arrangements.
Trager shall also be entitled to participate in any other employee benefit plan
or arrangement made available in the future by i3 Mobile to its executives and
key management employees.

    (d) Vacation. Trager shall be entitled to paid vacation days in each
calendar year determined by i3 Mobile from time to time, in accordance with i3
Mobile's standard vacation policy, prorated in any calendar year during which
Trager is employed hereunder for less than an entire year in accordance with the
number of days in such year during which he is so employed. Trager shall also be
entitled to all paid holidays given by i3 Mobile to its executives and key
management employees

    (e) Incentive Compensation. i3 Mobile agrees to pay Trager a bonus (the
"Bonus") which shall be determined by the President and Chief Executive Officer
of i3 Mobile, in addition to and separate from his Base Salary and subject to
the achievement of certain mutually agreed upon performance goals, in an amount
up to one-third (1/3) of his Base Salary. Trager shall be entitled to the Bonus
on a pro-rata basis for partial achievement of the performance goals.

6.      Termination.

        Trager's employment hereunder shall be terminated upon Trager's death
and may be terminated as follows:

        (a) By i3 Mobile for "Cause." For purposes of this Agreement, a
termination for Cause shall occur if Trager has (i) willfully failed to comply
with any of the material terms of this Agreement, (ii) willfully and repeatedly
failed to perform his duties hereunder, (iii) engaged in gross misconduct
materially injurious to i3 Mobile or (iv) been convicted of, or pleaded nolo
contendere to, a felony or a crime of moral turpitude; provided, however, that
Trager shall receive thirty (30) days' advance written notice specifying the
actions constituting Cause and Trager shall not have cured the actions
constituting Cause during such thirty (30) day period.

        (b) By i3 Mobile due to Trager's "Disability." For purposes of this
Agreement, a termination for Disability shall occur (i) upon the thirtieth
(30th) day after i3 Mobile has provided a written termination notice to Trager

<PAGE>   3

supported by a written statement from a reputable independent physician to the
effect that Trager shall have become so incapacitated as to be unable to resume,
within the ensuing twelve (12) months, his employment hereunder by reason of
physical or mental illness or injury, or (ii) upon rendering of a written
termination notice by i3 Mobile after Trager has been unable to substantially
perform his duties hereunder for six (6) consecutive months or for nine (9)
months in any twelve (12) month period (exclusive of any vacation permitted
under Section 5(f) hereof) by reason of any physical or mental illness. For
purposes of this Section 6(b), Trager agrees to make himself available and to
cooperate in any reasonable examination by a reputable independent physician
retained by i3 Mobile.

        (c) By Trager for "Good Reason upon Change in Control." For purposes of
this Agreement, "GOOD REASON" shall mean any of the following that occurs
coincident with or following a Change in Control, if not cured and corrected by
i3 Mobile or its successor within ten business days after written notice thereof
by Trager to i3 Mobile or its successor: (i) any change in Trager's title or
position that constitutes a material diminution in authority as compared to the
authority of Trager's title or position immediately prior to the occurrence of
the Change in Control; (ii) any material reduction in the Trager's annual base
salary as in effect on the effective date of the Change in Control; (iii) the
relocation of the principal executive offices of i3 Mobile in excess of fifty
(50) miles from their present location not consented to by Trager, or (iv) a
substantial diminution in the Trager's duties and responsibilities (other than a
change due to Trager's Total and Permanent Disability or as an accommodation
under the Americans With Disabilities Act); provided, however, that no
diminution of title, position, duties or responsibilities shall be deemed to
occur solely because i3 Mobile becomes a subsidiary of another corporation or
entity or because there has been a change in the reporting hierarchy incident
thereto involving Trager. "CHANGE IN CONTROL" means: (i) the effective date of
any merger, share exchange, consolidation or other reorganization or business
combination of i3 Mobile if immediately after such transaction either (A)
persons who were directors of i3 Mobile immediately prior to such transaction do
not constitute at least a majority of the directors of the surviving entity, or
(B) persons who hold a majority of the outstanding voting securities entitled to
vote generally in the election of directors of the surviving entity are not
persons who held a majority of the voting capital stock of i3 Mobile immediately
prior to such transaction; (ii) the closing of a sale or conveyance of all or
substantially all of the assets of i3 Mobile; (iii) an acquisition (other than
from i3 Mobile) in a transaction or a series of related transactions by any
person, entity or "group," within the meaning of Section 13(d)(3) or 14(d)(2) of
the Securities Exchange Act of 1934 (the "EXCHANGE ACT"), (excluding for this
purpose, (A) i3 Mobile or its subsidiaries, (B) any employee benefit plan of i3
Mobile or its subsidiaries which acquires beneficial ownership of voting
securities of i3 Mobile, (C) an underwriter temporarily holding securities
pursuant to an offering of such securities, or (D) any corporation owned,
directly or indirectly, by the stockholders of i3 Mobile in substantially the
same proportions as their ownership of the then outstanding voting securities of
i3 Mobile entitled to vote generally in the election of directors) of beneficial
ownership, within the meaning of Rule 13d-3 promulgated under the Exchange Act,
of 50% or more of either the then outstanding shares of common stock or the
combined voting power of i3 Mobile's then outstanding voting securities entitled
to vote generally in the election of directors; (iv) individuals who were the
Board's nominees for election as directors immediately prior to a meeting of the
stockholders of i3 Mobile involving an actual or threatened election contest
relating to the election of the directors of i3 Mobile, as such terms are used
in Rule 14a-11 of Regulation 14A promulgated under the Exchange Act, cease to
constitute a majority of the Board following the election; or (v) the
dissolution or liquidation of i3 Mobile.

7.      Compensation upon Termination.

    (a) In the event of the termination of Trager's employment as a result of
Trager's death, i3 Mobile shall (i) pay to Trager's estate his Base Salary and
Bonus through the date of his death and (ii) for the longer of twelve (12)
months following his death or the balance of the Term (as if such termination
had not occurred) provide continuation coverage to the members of Trager's
family under all major medical and other health, accident, life or other
disability plans and programs in which such family members participated
immediately prior to his death.

    (b) In the event of the termination of Trager's employment by i3 Mobile for
Cause or by Trager other than for Good Reason upon Change in Control, i3 Mobile
shall pay to Trager his Base Salary and accrued Bonus through the date of his
termination, and Trager shall have no further entitlement to any other
compensation or benefits from i3 Mobile.

<PAGE>   4

    (c) In the event of the termination of Trager's employment by i3 Mobile due
to Disability, i3 Mobile shall pay to Trager his Base Salary and accrued Bonus
through the date of his termination. In addition, for twelve (12) months
following any such termination, i3 Mobile shall (i) continue to pay Trager the
Base Salary in effect at the time of such termination less the amount, if any,
then payable to Trager under any disability benefits of i3 Mobile and (ii)
provide Trager continuation coverage under all major medical and other health,
accident, life or other disability plans and programs in which Trager
participated immediately prior to such termination.

    (d) In the event that Trager's employment is terminated (i) by i3 Mobile
other than (A) as a result of Trager's death or (B) for reasons specified in
Section 6(a) or (b) or (ii) by Trager for Good Reason upon Change in Control, i3
Mobile shall continue to pay to Trager his Base Salary and Bonus for six (6)
months following any such termination and provide Trager continuation coverage
under all major medical and other health, accident, life or other disability
plans or programs in which Trager participated immediately prior to such
termination for the same period. Notwithstanding the foregoing, the amounts
otherwise payable to Trager pursuant to this Section 7(d) shall be subject to
reduction (but not below zero) to the extent determined necessary by i3 Mobile
to prevent any payments or benefits to or for the benefit of Trager (whether
pursuant to this Agreement or any other plan, arrangement or agreement) from
being treated as a "parachute payment" under Section 280G of the Internal
Revenue Code of 1986, as amended. In the event that Trager's employment is
terminated by Trager for Good Reason upon Change in Control, all stock options
and other equity incentive awards granted to Trager by i3 Mobile shall
immediately fully vest on an accelerated basis and be exercisable for a 30-day
period following the occurrence of the event comprising Good Reason upon Change
in Control.

    (e) If Trager disputes the termination of his employment by i3 Mobile
pursuant to Section 6(a) or 6(b) herein and such dispute results in a final
determination to the effect that i3 Mobile did not have a proper basis for such
termination, i3 Mobile shall promptly pay to Trager all payments Trager would
have been entitled to receive had his employment hereunder had not been
improperly terminated; provided, however, that any payments or benefits under
this Section 7(e) shall be reduced by the amount of any payments or benefits
provided under any other provision of Section 7 hereof.

    (f) The continuation coverage under any major medical and other health,
accident, life or other disability plans and programs for the periods provided
in Section 7(a), 7(c) and 7(d) shall be provided (i) at the expense of i3 Mobile
and (ii) in satisfaction of i3 Mobile's obligation under Section 4980B of the
Internal Revenue Code (and any similar state law) with respect to the period of
time such benefits are continued hereunder.

    (g) This Section 7 sets forth the only obligations of i3 Mobile with respect
to the termination of Trager's employment with i3 Mobile, and Trager
acknowledges that, upon the termination of his employment, he shall not be
entitled to any payments or benefits which are not explicitly provided herein.

8.      Covenant Regarding Inventions and Copyrights.

        Trager shall disclose promptly to i3 Mobile any and all inventions,
discoveries, improvements and patentable or copyrightable works initiated,
conceived or made by him, either alone or in conjunction with others, during the
Term and related to the business or activities of i3 Mobile and he assigns all
of his interest therein to i3 Mobile or its nominee; whenever requested to do so
by i3 Mobile, Trager shall execute any and all applications, assignments or
other instruments which i3 Mobile shall deem necessary to apply for and obtain
letters patent or copyrights of the United States or any foreign country, or
otherwise protect i3 Mobile's interest therein. These obligations shall continue
beyond the conclusion of the Term with respect to inventions, discoveries,
improvements or copyrightable works initiated, conceived or made by Trager
during the Term and shall be binding upon Trager's assigns, executors,
administrators and other legal representatives.

9.      Protection of Confidential Information.

        Trager acknowledges that he has been and will be provided with
information about, and his employment by i3 Mobile will, throughout the Term,
bring him into close contact with, many confidential affairs of i3 Mobile and
its subsidiaries, including proprietary information about costs, profits,
markets, sales, products, key personnel, pricing policies, operational methods,
technical processes and other business affairs and methods, plans for future
developments and other information not readily available to the public, all of
which are highly confidential and proprietary and all of which were developed by
i3 Mobile at great effort and expense. Trager

<PAGE>   5

further acknowledges that the services to be performed by him under this
Agreement are of a special, unique, unusual, extraordinary and intellectual
character, that the business of i3 Mobile will be conducted throughout the world
(the "Territory"), that its services will be marketed throughout the Territory,
that i3 Mobile competes and will compete in all of its business activities with
other organizations which are located in any part of the Territory and that the
nature of the relationship of Trager with i3 Mobile is such that Trager is
capable of competing with i3 Mobile from nearly any location in the Territory.
In recognition of the foregoing, Trager covenants and agrees during the Term and
for a period of five (5) years thereafter:

    (i) That he will keep secret all confidential matters of i3 Mobile and not
disclose them to anyone outside of i3 Mobile, either during or after the Term,
except with i3 Mobile's prior written consent or, if during the Term, in the
performance of his duties hereunder, Trager makes a good faith determination
that it is the best interest of i3 Mobile and to disclose such matters;

    (ii) That he will not make use of any such confidential matters for his own
purposes or the benefit of anyone other than i3 Mobile; and

    (iii) That he will deliver promptly to i3 Mobile on termination of this
Agreement, or at any time i3 Mobile may so request, all confidential memoranda,
notes, records, reports and other confidential documents (and all copies
thereof) relating to the business of i3 Mobile, which he may then possess or
have under his control.

10.     Restriction on Competition, Interference and Solicitation.

        In recognition of the considerations described in Section 9 hereof,
Trager covenants and agrees that, during the Term and for a period of one (1)
year or such longer period of time during which Trager is continuing to receive
compensation from i3 Mobile after such termination, Trager will not, directly or
indirectly, (A) enter into the employ of, or render any services to, any person,
firm or corporation engaged in any business directly competitive with the
business of i3 Mobile in any part of the Territory in which i3 Mobile is
actively engaged in business on the date of termination; (B) engage in any such
business for his own account; (C) become interested in any such business as an
individual, partner, shareholder, creditor, director, officer, principal, agent,
employee, trustee, consultant, advisor, franchisee or in any other relationship
or capacity; or (D) interfere with i3 Mobile's relationship with, or endeavor to
employ or entice away from i3 Mobile any person, firm, corporation, governmental
entity or other business organization who or which is or was an employee,
customer or supplier of, or maintained a business relationship with, i3 Mobile
at any time (whether before or after the Term), or which i3 Mobile has solicited
or prepared to solicit; provided, however, that the provisions of clause (A)
shall not be deemed to preclude Trager from engagement by a corporation some of
the activities of which are competitive with the business of i3 Mobile if
Trager's engagement does not relate, directly or indirectly, to such competitive
business, and nothing contained in this Section 10 shall be deemed to prohibit
Trager from acquiring or holding, solely for investment, publicly traded
securities of any corporation some of the activities of which are competitive
with the business of i3 Mobile so long as such securities do not, in the
aggregate, constitute more than five percent (5%) of any class or series of
outstanding securities of such corporation.

11.     Specific Remedies.

        For purposes of Sections 8, 9 and 10 of this Agreement, references to i3
Mobile shall include all current and future majority-owned subsidiaries of i3
Mobile and all current and future joint ventures in which i3 Mobile may from
time to time be involved. It is understood by Trager and i3 Mobile that the
covenants contained in this Section 11 and in Sections 8, 9 and 10 hereof are
essential elements of this Agreement and that, but for the agreement of Trager
to comply with such covenants, i3 Mobile would not have agreed to enter into
this Agreement. i3 Mobile and Trager have independently consulted with their
respective counsel and have been advised concerning the reasonableness and
propriety of such covenants with specific regard to the nature of the business
conducted by i3 Mobile and all interests of i3 Mobile. Trager agrees that the
covenants of Sections 8, 9 or 10 hereof are reasonable and valid. If Trager
commits a breach of any of the provisions of Sections 8, 9 or 10 hereof, such
breach shall be deemed to be grounds for termination for Cause. In addition,
Trager acknowledges that i3 Mobile may have no adequate remedy at law if he
violates any of the terms hereof. Trager therefore understands and agrees that
i3 Mobile shall have (i) the right to have such provisions specifically enforced
by any court having equity jurisdiction, it being acknowledged and agreed that
any such breach will cause irreparable injury to i3 Mobile and that money
damages will not provide an adequate remedy to i3 Mobile, and (ii) the right

<PAGE>   6

to require Trager to account for and pay over to i3 Mobile all compensation,
profits, monies, accruals, increments and other benefits (collectively
"Benefits") derived or received by Trager as a result of any transaction
constituting a breach of any of the provisions of Sections 8, 9 or 10 and Trager
hereby agrees to account for and pay over such Benefits to i3 Mobile.

12.     Independence, Severability and Non-Exclusivity.

        Each of the rights enumerated in Sections 8, 9 or 10 hereof and the
remedies enumerated in Section 11 hereof shall be independent of the others and
shall be in addition to and not in lieu of any other rights and remedies
available to i3 Mobile at law or in equity. If any of the covenants contained in
Sections 8, 9 or 10, or any part of any of them, is hereafter construed or
adjudicated to be invalid or unenforceable, the same shall not affect the
remainder of the covenant or covenants or right or remedies which shall be given
full effect without regard to the invalid portions. The parties intend to and do
hereby confer jurisdiction to enforce the covenants contained in Section 8, 9 or
10 and the remedies enumerated in Section 11 upon the federal and state courts
of Connecticut sitting in Fairfield County. If any of the covenants contained in
Sections 8, 9 or 10 is held to be invalid or unenforceable because of the
duration of such provision or the area covered thereby, the parties agree that
the court making such determination shall be the power to reduce the duration
and/or area of such provision and in its reduced from said provision shall then
be enforceable. No such holding of invalidity or unenforceability in one
jurisdiction shall bar or in any way affect i3 Mobile's right to the relief
provided in Section 11 or otherwise in the courts of any other state or
jurisdiction within the geographical scope of such covenants as to breaches of
such covenants in such other respective states or jurisdictions, such covenants
being, for this purpose, severable into diverse and independent covenants.

13. Disputes. If i3 Mobile or Trager shall dispute any termination of Trager's
employment hereunder or if a dispute concerning any payment hereunder shall
exist:

    (a) either party shall have the right (but not the obligation), in addition
to all other rights and remedies provided by law, to compel binding, enforceable
and non-appealable arbitration of the dispute in the City of New York under the
rules of the American Arbitration Association by giving written notice of
arbitration to the other party within thirty (30) days after notice of such
dispute has been received by the party to whom notice has been given; and

    (b) if such dispute (whether or not submitted to arbitration pursuant to
Section 13(a) hereof) results in a determination that (i) i3 Mobile did not have
the right to terminate Trager's employment under the provisions of this
Agreement or (ii) the position taken by Trager concerning payments to Trager is
correct, i3 Mobile shall promptly pay, or if theretofore paid by Trager, shall
promptly reimburse Trager for, all costs and expenses (including reasonable
attorneys' fees) reasonably incurred by Trager in connection with such dispute.

14.     Successors; Binding Agreement.

        In the event of a future disposition by i3 Mobile (whether direct or
indirect), by sale of assets or stock, merger, consolidation or otherwise of all
or substantially all of its business and/or assets in a transaction to which
Trager consents, i3 Mobile will require any successor, by agreement in form and
substance satisfactory to Trager, to expressly assume and agree to perform this
Agreement in the same manner and to the same extent that i3 Mobile would be
required to perform if no such disposition had taken place. This Agreement and
all rights of Trager hereunder shall inure to the benefit of, and be enforceable
by, Trager's personal or legal representatives, executors, administrators,
administrators cta, successors, heirs, distributees, devisees and legatees. If
Trager should die while any amount would still be payable to him hereunder if he
had continued to live, all such amounts, unless otherwise provided herein, shall
be paid in accordance with the terms of this Agreement to Trager's estate.

15.     Notices.

        All notices, consents and other communications required or permitted to
be given by any party hereunder shall be in writing (including telecopy or other
similar writing) and shall be given be personal delivery, certified or
registered mail, postage prepaid, or telecopy (or other similar writing) as
follows:
