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. Leventhal understands and accepts that all terms
contained herein are subject to the formal written ratification and approval of
the Compensation Committee and/or the Board of Directors of i3 Mobile.

3.  Duties; Best Efforts; Indemnification

Leventhal shall serve as Senior Vice President, Marketing 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 Senior Vice President, Marketing. Leventhal 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 Leventhal's powers and duties so prescribed shall
not be inconsistent with Leventhal's position and duties hereunder.

Leventhal shall devote her business time, attention and energies to the business
and affairs of i3 Mobile, shall use her best efforts to advance the best
interests of i3 Mobile and shall not, during the Term, be actively engaged in

advantage, that will interfere with the performance by Leventhal of her duties
hereunder or Leventhal'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 Leventhal
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 Leventhal 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 Leventhal of services for, or the
acting by Leventhal as a director, officer, or employee of, i3 Mobile, or any
other person or enterprise at i3 Mobile's request if Leventhal acted in good
faith and in a manner she 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 her 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

terms. Leventhal agrees that, if it is finally judicially determined or finally
determined by an arbitrator that she is not or was not entitled to any amounts
paid on her behalf or for which she has been 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,
Leventhal shall promptly reimburse i3 Mobile for such amounts.

perform her duties hereunder, (iii) engaged in gross misconduct materially
injurious to i3 Mobile or (iv) been convicted of, or pleaded nolo contendere to,

constituting Cause, Leventhal shall not have cured the actions constituting
Cause during such thirty (30) day period and Leventhal shall be given a

be unable to resume, within the ensuing twelve (12) months, her employment
hereunder by reason of physical or mental illness or injury, or (ii) upon
rendering of a written termination notice by i3 Mobile after Leventhal has been

of 500/c 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

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.

                                       5

<PAGE>

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

(d) In the event that Leventhal's employment is terminated (i) by i3 Mobile
other than (A) as a result of Leventhal's death or (B) for reasons specified in
Section 6(a) or (b) or (ii) by Leventhal for Good Reason upon Change in Control
or upon Change of CEO, i3 Mobile shall continue to pay Leventhal (1) if

all major medical and other health, accident, life or other disability plans or
programs in which Leventhal participated immediately prior to such termination
and continue all automobile lease payments specified in Section 5(f) for the
same period. Notwithstanding the foregoing, the amounts otherwise payable to
Leventhal 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 Leventhal (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 Leventhal's employment is terminated by
Leventhal for Good Reason upon Change in Control, all stock options and other
equity incentive awards granted to Leventhal 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 Leventhal disputes the termination of her 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 Leventhal all payments Leventhal
would have been entitled to receive had her 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.

                                       6

<PAGE>

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

8.  Covenant Regarding Inventions and Copyrights

Leventhal 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 she assigns all
of her interest therein to i3 Mobile or its nominee; whenever requested to do so
by i3 Mobile, Leventhal 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 Leventhal
during the Term and shall be binding upon Leventhal's assigns, executors,
administrators and other legal representatives.

9.  Protection of Confidential Information

Leventhal acknowledges that she has been and will be provided with information
about, and her 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. Leventhal 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 Leventhal with
i3 Mobile is such that Leventhal is capable of competing with i3 Mobile from
nearly any location in the Territory. In recognition of the foregoing, Leventhal
covenants and agrees during the Term and for a period of five (5) years
thereafter:

(i) That she 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 her duties hereunder, Leventhal makes a good faith determination
that it is the best interest of i3 Mobile and to disclose such matters;

                                       7

<PAGE>

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

(iii) That she 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 she may then possess or
have under her control.

10.   Restriction on Competition, Interference and Solicitation

In recognition of the considerations described in Section 9 hereof, Leventhal
covenants and agrees that, during the Term and for a period of one (1) year or
such longer period of time during which Leventhal is continuing to receive
compensation from i3 Mobile after such termination, Leventhal 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; (8) engage in any such
business for her own account; (C) become interested in any such business as an
individual, partner, shareholder, creditor, director, officer, principal, agent,
employee, trustee, consultant, advisor, francheree 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 Leventhal from engagement by a corporation some
of the activities of which are competitive with the business of i3 Mobile if
Leventhal's engagement does not relate, directly or indirectly, to such
competitive business, and nothing contained in this Section 10 shall be deemed
to prohibit Leventhal 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 (50/0) 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 Leventhal 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 Leventhal to
comply with such covenants, i3 Mobile would not have agreed to enter into this
Agreement. i3 Mobile and Leventhal 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. Leventhal agrees that

                                       8

<PAGE>

the covenants of Sections 8, 9 or 10 hereof are reasonable and valid. If
Leventhal 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, Leventhal acknowledges that i3 Mobile may have no adequate remedy at
law if she violates any of the terms hereof. Leventhal 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 Leventhal to account for and pay over to i3 Mobile
all compensation, profits, monies, accruals, increments and other benefits
(collectively "Benefits") derived or received by Leventhal as a result of any
transaction constituting a breach of any of the provisions of Sections 8, 9 or
10 and Leventhal 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 Leventhal shall dispute any termination of Leventhal'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

                                       9

<PAGE>

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 Leventhal's employment under the provisions of this Agreement
or (ii) the position taken by Leventhal concerning payments to Leventhal is
correct, i3 Mobile shall promptly pay, or if theretofore paid by Leventhal,
shall promptly reimburse Leventhal for, all costs and expenses (including
reasonable attorneys' fees) reasonably incurred by Leventhal 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
Leventhal consents, i3 Mobile will require any successor, by agreement in form
and substance satisfactory to Leventhal, 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 Leventhal hereunder shall inure to the benefit of,
and be enforceable by, Leventhal's personal or legal representatives, executors,
administrators, administrators cta, successors, heirs, distributees, devisees
and legatees. If Leventhal should die while any amount would still be payable to
him hereunder if she had continued to live, all such amounts, unless otherwise
provided herein, shall be paid in accordance with the terms of this Agreement to
Leventhal'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:
