EXHIBIT 10.33

                              EMPLOYMENT AGREEMENT

       EMPLOYMENT AGREEMENT, dated as of the 1st day of October, 1999, between
ACE*COMM Corporation (the "Company") and S. Joseph Dorr (the "Executive").

       WHEREAS, the Board of Directors of the Company has determined that it is
in the best interests of the Company and its shareholders to assure that the
Company will have the continued dedication of the Executive, notwithstanding the
possibility, threat or occurrence of a corporate reorganization or Change of
Control (as defined below) of the Company, and

        WHEREAS, the Board believes it is imperative to diminish the inevitable
distraction of the Executive by virtue of the personal uncertainties and risks
created by the recovery period or by a pending or threatened corporate
reorganization or Change of Control and, therefore, it is in the best interests
of the Company and its shareholders to provide the Executive with compensation
and benefits arrangements upon termination which ensure that the compensation
and benefits expectations of the Executive will be satisfied and are competitive
with those of other corporations.

       NOW, THEREFORE, in order to accomplish these objectives, and in
consideration of the promises and mutual agreements herein contained, the
Company and Executive hereby agree as follows:

       1. EMPLOYMENT, DUTIES.
       Subject to the provisions set forth elsewhere in this Agreement, the
Company hereby employs the Executive as its Executive Vice President - Business
Development and Customer Engagement (or such other title as is appropriate from
time to time as is determined by the Chief Executive Officer or President), with
such responsibilities and authority as shall be assigned to him from time to
time by the Board of Directors or the Chief Executive Officer or President of
the Company, provided that after a Change of Control, the Executive's position,
authority, duties and responsibilities shall be at least commensurate with those
held, exercised and assigned during the 120-day period immediately preceding the
Change of Control.

       Initially, the Executive's duties shall include duties as directed by the
Chief Executive Officer or President from time to time, including those set
forth on Exhibit A.

       The Executive's principal place of employment shall be at the Company's
main headquarters, in Gaithersburg, Maryland, subject to such travel as may be
required by his employment.

       The Executive hereby agrees to remain in the employ of the Company
subject to the terms and conditions of this Agreement, for the Term of this
Agreement (defined below) and to perform his duties faithfully, loyally and to
report to, and follow the directions of, the Chief Executive Officer or
President. During the Term, and excluding any periods of vacation and sick leave
to which the Executive is entitled, the Executive agrees to devote his full
business time and best efforts to the business and affairs of the Company and,
to the extent necessary to discharge the responsibilities assigned to the
Executive hereunder, to use his best efforts to perform faithfully and
efficiently such responsibilities. During the Term it shall not be a violation
of this Agreement for the Executive to (A) serve on corporate, civic or
charitable boards or committees, (B) deliver lectures, fulfill speaking
engagements or teach at educational institutions and (C) manage personal
investments, so long as such activities do not materially interfere with the
performance of the Executive's responsibilities as an employee of the Company in
accordance with this Agreement.

       The Executive represents and warrants that there are no agreements or
arrangements, whether written or oral, in effect which would prevent him from
rendering exclusive services to the Company

<PAGE>   2

during the term hereof, and that he has not made and will not make any
commitment, agreement or arrangement, or do any act, in conflict with this
Agreement and that entering into this Agreement will not be in violation of any
other agreement.

       2. TERM.
       The term of the Executive's employment under this Agreement shall
commence on October 1, 1999 (the "Effective Date") and shall end on the third
anniversary of the Effective Date, unless sooner terminated, as provided herein,
or renewed by mutual agreement of the parties (the "Term").

       3. COMPENSATION.
       As compensation for all services to be rendered pursuant to this
Agreement, the Company shall pay the Executive, during the Term, the following:

     "Base Salary" payable bi-weekly, less such amounts as shall be required to
     be withheld by applicable laws and regulations. The "Base Salary" shall be
     $175,000 per year, subject to consideration by the Compensation Committee
     of the Board of Directors as of October 1 of each year for increases as
     appropriate.

     "Bonus" In addition to his Base Salary, the Executive shall be eligible to
     receive with respect to each fiscal year (beginning with respect to the
     2000 fiscal year), payable on October 1, 2000, 2001 and 2002, respectively,
     for the prior fiscal year pursuant to a plan established for, and applied
     consistently to, all executives, a bonus of (1) up to $100,000 payable in
     cash and (2) an option for up to 20,000 shares of Common Stock. Such Bonus
     shall be payable, based on the Company's financial performance and personal
     objectives as determined by the Chief Executive Officer or President and
     the Board of Directors.

 Following a Change of Control, the Executive shall be eligible, for each fiscal
year ending during the balance of the Term, an annual bonus (the "Annual Bonus")
in cash and options at least equal to the average of the bonuses offered to the
Executive under the Company's annual bonus plan for the preceding three full
fiscal years prior to the Change of Control (the "Average Annual Bonus"). Each
such Annual Bonus shall be paid no later than the end of the third month of the
fiscal year next following the fiscal year for which the Annual Bonus is
awarded, unless the Executive shall elect to defer the receipt of such Annual
Bonus.

       4. OPTION GRANT.
       In connection with his employment, the Executive was granted an option
(the "Option") exercisable for 90,000 shares of Common Stock (the "Option
Shares") exercisable at $3.938 per share, the terms and conditions of which are
set forth in the Option Agreement effective as of August 24,1999, as amended and
restated in the Amended and Restated Omnibus Stock Plan Non-Qualified Stock
Option Grant Agreement dated of even date herewith and a copy of which is
attached hereto (as amended, the "Option Agreement"). To the extent that the
terms of the Option evidenced in the Option Agreement and in the Amended and
Restated Omnibus Stock Plan (the "Plan") are in any way inconsistent with the
terms of this Agreement, the terms of the Option as set forth in the Option
Agreement and Plan shall supersede any terms set forth herein with respect
thereto.

       5. PERQUISITES.

       During the Term the Executive shall be eligible to participate in benefit
plans generally available to all executive level employees and reimbursement for
business expenses in accordance with Company policy.

       The Company agrees to use reasonable efforts to maintain liability
insurance for present and former directors and officers during the Term and for
up to one year thereafter on substantially the terms of

<PAGE>   3

the policy currently maintained by the Company, provided that the premium cost
of such insurance to the Company does not increase substantially over the cost
paid for the Company's current policy - including any subsequent adjustments
related to extraordinary events affecting the current policy (which was entered
into in August 1999).

       After a Change of Control, the Executive shall be eligible to participate
in benefit plans at least as favorable to the Executive as were available to the
Executive at the Company within the 120 days prior to the Change of Control. In
addition, specifically, if, as a result of a Change of Control, the Executive is
asked to relocate his employment to a location more than 40 miles away from the
Executive's residence, the Executive shall be entitled to receive relocation
benefits of up to $90,000, subject to presentation of reasonable documentation.

       6. TERMINATION AND COMPENSATION THEREFOR PRIOR TO A CHANGE OF CONTROL.

       6.1 DEATH: If the Executive dies during the Term and prior to a Change of
Control, this Agreement shall terminate automatically as of the date of death of
the Executive. In the event of such termination, all compensation and other
benefits payable or provided hereunder shall cease as of the date of termination
(except to the extent that death benefits are then payable), and Base Salary,
unpaid Bonus from a prior year, and all accrued benefits (if any) then payable
to the Executive pursuant to the terms of any plans or arrangements referred to
in Sections 3 or 5, shall be paid to the Executive (or to his heirs, legatees
and/or personal representatives) through the date of termination. No Bonus shall
be payable with respect to the year in which the Executive dies. Any bonus, the
payment of which was deferred pursuant to the terms of the Executive Bonus Plan,
will be paid in full. The Option will remain exercisable for up to one year from
the date of death in accordance with the terms of the Option Agreement with
respect to Option Shares that have vested as of the date of death. Unvested
Option Shares will be deemed cancelled upon the date of death.

       6.2 DISABILITY: If the Company determines in good faith that the
Disability of the Executive has occurred during the Term (pursuant to the
definition of Disability set forth below), it may give to the Executive written
notice of its intention to terminate the Executive's employment. In such event,
the Executive's employment with the Company shall terminate effective on the
30th day after the date of such notice (the "Disability Effective Date"),
provided that, within the 30 days after such receipt, the Executive shall not
have returned to full-time performance of the Executive's duties. For purposes
of this Agreement, "Disability" shall mean the Executive' incapacity due to
mental or physical illness which is determined to be total and permanent by a
physician selected by the Company or its insurers and reasonably acceptable to
the Executive or the Executive's legal representative. In the event of such
termination, all compensation and other benefits payable or provided hereunder
shall cease as of the effective date of termination (except to the extent that
disability benefits are then payable), and Base Salary, unpaid Bonus from a
prior year, and all accrued benefits (if any) then payable to the Executive
pursuant to the terms of any plans or arrangements referred to in Sections 3 or
5, shall be paid to the Executive (or to his guardian or personal
representatives) through the date of termination. No Bonus shall be payable with
respect to the year in which the Executive is determined by the Board of
Directors to have become disabled. The Option will remain exercisable for up to
90 days from the effective date of termination in accordance with the terms of
the Option Agreement, with respect to Option Shares that have vested as of the
effective date of termination. Unvested Option Shares will be deemed cancelled
upon the effective date of termination.

       6.3 TERMINATION AT ELECTION OF THE COMPANY:

       (a) FOR CAUSE: Notwithstanding any other provision of this Agreement, the
Company may terminate the Executive's employment hereunder at any time prior to
a Change of Control, effective after sufficient notice of such termination and
failure to cure, upon the occurrence of any of the following: (i) the
Executive's engaging in conduct that constitutes gross neglect or willful
misconduct in carrying out his duties under this Agreement; (ii) the Executive's
engaging in any acts or omissions involving dishonesty or that demonstrate a
lack of integrity; (iii) the Executive's making knowing material
misrepresentations to

<PAGE>   4

the Company that injure the business and affairs of the Company, monetarily or
otherwise; (iv) the Executive's committing a material breach of any of his
obligations under this Agreement. Such termination will be deemed for "Cause."

       In the event of termination of the Executive's employment for Cause, all
compensation and other benefits payable or provided hereunder shall cease as of
the date of termination and Base Salary, unpaid Bonus from a prior year, and all
accrued benefits (if any) then payable to the Executive pursuant to the terms of
any plans or arrangements referred to in Sections 3 or 5, shall be paid to the
Executive through the date of termination. No Bonus shall be payable with
respect to the year in which the Executive is terminated for Cause. Any bonus,
the payment of which was deferred pursuant to the terms of the Executive Bonus
Plan, will be paid in full. Upon termination of the Executive for Cause, the
Option shall terminate immediately and no longer be exercisable.

       (b) OTHER THAN FOR CAUSE: In addition to the Company's right to terminate
the Executive's employment pursuant to Sections 6.3(a), prior to a Change of
Control the Company may, for any reason or for no reason, terminate the
Executive's employment upon written notice to the Executive effective upon the
date of the notice. In the event of such termination, all compensation and other
benefits payable or provided hereunder shall cease as of the date of termination
and Base Salary, unpaid Bonus from a prior year, and all accrued benefits (if
any) then payable to the Executive pursuant to the terms of any plans or
arrangements referred to in Sections 3 or 5, shall be paid to the Executive
through the date of termination. No Bonus shall be payable with respect to the
year in which the Executive is terminated other than for Cause. Any bonus, the
payment of which was deferred pursuant to the terms of the Executive Bonus Plan,
will be paid in full. As additional compensation for such termination, the
Company shall pay the Executive upon such termination a lump sum equal to one
year's Base Salary as is in effect as of immediately prior to such termination.

       If the termination occurs before October 1, 2000, 30,000 of the Option
Shares (not previously vested) shall vest and become exercisable as of the date
of termination; if the termination occurs on or after October 1, 2000 but before
October 1, 2001, the remaining 30,000 of the Option Shares shall vest and become
exercisable as of the date of termination. The Option will remain exercisable
for up to 90 days from the effective date of termination in accordance with the
terms of the Option Agreement with respect to Option Shares that have vested as
of the effective date of termination. Unvested Option Shares will be deemed
cancelled upon the effective date of termination.

       6.4 TERMINATION BY THE EXECUTIVE: Notwithstanding any other provision of
this Agreement, prior to a Change of Control the Executive may terminate his
employment upon written notice of termination delivered to the Board of
Directors, effective upon the date of receipt of such notice by the Board. In
the event of such termination, all compensation and other benefits payable or
provided hereunder shall cease as of the date of termination, all accrued
benefits (if any) then payable to the Executive pursuant to the terms of any
plans or arrangements referred to in Sections 3 or 5, shall be paid to the
Executive through the date of termination and Base Salary shall be paid to the
Executive through a date that is 60 days from the date of termination. No Bonus
shall be payable with respect to the year in which such termination is
effective. Any bonus, the payment of which was deferred pursuant to the terms of
the Executive Bonus Plan, will be paid in full. Upon termination by the
Executive, the unvested portion of the Option shall terminate immediately and no
longer be exercisable; the vested portion of the Option shall remain exercisable
for 90 days and thereafter shall terminate.

       7. Termination and Compensation therefor following a Change of Control.

       7.1 DEFINITION OF CHANGE OF CONTROL: For the purpose of this Agreement, a
"Change of Control" shall mean:

       (a)    The acquisition by any individual, entity or group (within the
       meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of
       1934, as amended (the "Exchange Act")) (a

<PAGE>   5

       "Person") of beneficial ownership (within the meaning of Rule 13d-3
       promulgated under the Exchange Act) of 51% or more of either (i) the then
       outstanding shares of common stock of the Company (the "Outstanding
       Company Common Stock") or (ii) the combined voting power of the then
       outstanding voting securities of the Company entitled to vote generally
       in the election of directors (the "Outstanding Company Voting
       Securities"); provided, however, that for purposes of this subsection
       (a), the following acquisitions shall not constitute a Change of Control:
       (i) any acquisition directly from the Company, (ii) any acquisition by
       the Company, (iii) any acquisition by any employee benefit plan (or
       related trust) sponsored or maintained by the Company or any corporation
       controlled by the Company or (iv) any acquisition by any corporation
       pursuant to a transaction which complies with clauses (A) and (B) of
       subsection (c) of this Section 7.1; or

              (b)    Individuals who, as of the date hereof, constitute the
       Board (the "Incumbent Board") cease for any reason to constitute at least
       a majority of the Board; provided, however, that any individual becoming
       a director subsequent to the date hereof whose election, or nomination
       for election by the Company's shareholders, was approved by a vote of at
       least a majority of the directors then comprising the Incumbent Board
       shall be considered as though such individual were a member of the
       Incumbent Board, but excluding, for this purpose, any such individual
       whose initial assumption of office occurs as a result of an actual or
       threatened election contest with respect to the election or removal of
       directors or other actual or threatened solicitation of proxies or
       consents by or on behalf of a Person other than the Board; or

              (c)    Consummation of a reorganization, merger or consolidation
       involving the Company or any subsidiary of the Company or sale or other
       disposition of all or substantially all of the assets of the Company (a
       "Business Combination"), in each case, unless, following such Business
       Combination, either (A)(i) all or substantially all of the individuals
       and entities who were the beneficial owners, respectively, of the
       Outstanding Company Common Stock and Outstanding Company Voting
       Securities immediately prior to such Business Combination beneficially
       own, directly or indirectly, more than 50% of, respectively, the then
       outstanding shares of common stock and the combined voting power of the
       then outstanding voting securities entitled to vote generally in the
       election of directors, as the case may be, of the corporation resulting
       from such Business Combination (including, without limitation, a
       corporation which as a result of such transaction owns the Company or all
       or substantially all of the Company's assets either directly or through
       one or more subsidiaries) in substantially the same proportions as their
       ownership, immediately prior to such Business Combination of the
       Outstanding Company Common Stock and Outstanding Company Voting
       Securities, as the case may be or (ii) at least a majority of the members
       of the board of directors of the corporation resulting from such Business
       Combination were members of the Incumbent Board at the time of the
       execution of the initial agreement, or of the action of the Board,
       providing for such Business Combination and (B) no Person (excluding any
       corporation resulting from such Business Combination or any employee
       benefit plan (or related trust) of the Company or such corporation
       resulting from such Business Combination) beneficially owns, directly or
       indirectly, 35% or more of, respectively, the then outstanding shares of
       common stock of the corporation resulting from such Business Combination
       or the combined voting power of the then outstanding voting securities of
       such corporation except to the extent that such ownership existed prior
       to the Business Combination.

       7.1 DEATH: If the Executive dies during the Term after a Change of
Control, this Agreement shall terminate automatically as of the date of death of
the Executive. In the event of such termination, all compensation and other
benefits payable or provided hereunder shall cease as of the date of termination
(except to the extent that death benefits are then payable), and Base Salary,
any unpaid Bonus from a prior year, and all accrued benefits (if any) then
payable to the Executive pursuant to the terms of any plans or arrangements
referred to in Sections 3 or 5, shall be paid to the Executive (or to his heirs,
legatees and/or personal representatives) through the date of termination. No
Bonus shall be payable with respect to the year in which the Executive dies. The
Option will remain exercisable for up to one year from the date of

<PAGE>   6

death in accordance with the terms of the Option Agreement with respect to
Option Shares that have vested as of the date of death. Unvested Option Shares
will be deemed cancelled upon the date of death.

       With respect to the provision of plans or arrangements pursuant to
Sections 3 or 5, these shall include, without limitation, and the Executive's
estate and/or beneficiaries shall be entitled to receive, benefits at least
equal to the benefits that would have been provided by the Company to the estate
and beneficiaries of the Executive under such plans, programs, practices and
policies relating to death benefits, if any, as in effect with respect to such
Executive and his beneficiaries at any time during the 120-day period
immediately preceding the Change of Control.

       7.2 DISABILITY: If during the Term and after a Change of Control the
Company determines in good faith that the Disability of the Executive has
occurred during the Term (pursuant to the definition of Disability set forth in
Section 6.2), it may give to the Executive written notice of its intention to
terminate the Executive's employment. In such event, the Executive's employment
with the Company shall terminate effective on the 30th day after the date of
such notice (the "Disability Effective Date"), provided that, within the 30 days
after such receipt, the Executive shall not have returned to full-time
performance of the Executive's duties. In the event of such termination, all
compensation and other benefits payable or provided hereunder shall cease as of
the effective date of termination (except to the extent that disability benefits
are then payable), and Base Salary, any unpaid Bonus from a prior year, and all
accrued benefits (if any) then payable to the Executive pursuant to the terms of
any plans or arrangements referred to in Sections 3 or 5, shall be paid to the
Executive (or to his guardian or personal representatives) through the date of
termination. No Bonus shall be payable with respect to the year in which the
Executive is determined by the Board of Directors to have become disabled. The
Option will remain exercisable for up to 90 days from the effective date of
termination in accordance with the terms of the Option Agreement, with respect
to Option Shares that have vested as of the effective date of termination.
Unvested Option Shares will be deemed cancelled upon the effective date of
termination.

       7.3 TERMINATION AT ELECTION OF THE COMPANY:

       (a) FOR CAUSE: Notwithstanding any other provision of this Agreement, the
Company may terminate the Executive's employment hereunder at any time after a
Change of Control upon the occurrence of any of the following: (i) the willful
and continued failure of the Executive to perform substantially the Executive's
duties with the Company or one of its affiliates (other than any such failure
resulting from incapacity due to physical or mental illness), after a written
demand for substantial performance is delivered to the Executive by the Board or
the Chief Executive Officer or President of the Company which identifies the
manner in which the Board or Chief Executive Officer or President believes that
the Executive has not substantially performed the Executive's duties, or (ii)
the willful engaging by the Executive in illegal conduct or gross misconduct
which is materially and demonstrably injurious to the Company. Following a
Change of Control, only such termination will be deemed for Cause.

       The cessation of employment of the Executive shall not be deemed to be
for Cause following a Change of Control unless and until there shall have been
delivered to the Executive a copy of a resolution duly adopted by the
affirmative vote of not less than a majority of the Board at a meeting of the
Board called and held for such purpose (after reasonable notice is provided to
the Executive and the Executive is given an opportunity, together with counsel,
to be heard before the Board), finding that, in the good faith opinion of the
Board, the Executive is guilty of the conduct described in subparagraph (i) or
(ii) above, and specifying the particulars thereof in detail.

       In the event of such termination of the Executive's employment, all
       compensation and other benefits payable or provided hereunder shall cease
       as of the date of termination and Base Salary, any unpaid Bonus from a
       prior year, and all accrued benefits (if any) then payable to the
       Executive pursuant to the terms of any plans or arrangements referred to
       in Sections 3 or 5, shall be paid to the Executive through the date of
       termination. No Bonus shall be payable with respect

<PAGE>   7

       to the year in which the Executive is so terminated for Cause. Upon
       termination of the Executive for Cause, the Option shall terminate
       immediately and no longer be exercisable.

       (b) OTHER THAN FOR CAUSE: In addition to the Company's right to terminate
the Executive's employment pursuant to Sections 7.3(a), following a Change of
Control the Company may, for any reason or for no reason, terminate the
Executive's employment upon written notice to the Executive. In the event of
such termination, all compensation and other benefits payable or provided
hereunder shall cease as of the date of termination and Base Salary, unpaid
Bonus from a prior year, and all accrued benefits (if any) then payable to the
Executive pursuant to the terms of any plans or arrangements referred to in
Sections 3 or 5, shall be paid to the Executive through the date of termination.
No Bonus shall be payable with respect to the year in which the Executive is
terminated other than for Cause. As additional compensation for such
termination, the Company shall pay the Executive upon such termination a lump
sum equal to one year's Base Salary as is in effect as of immediately prior to
such termination. In addition, any Option Shares that are unvested as of the
date of termination shall immediately vest and become exercisable as of the
effective date of termination. The Option shall be exercisable with respect to
such accelerated shares and any other Option Shares previously vested as of the
effective date of termination and shall remain exercisable for 90 days from the
effective date of termination.

       7.4        Termination by the Executive:

       (a) FOR GOOD REASON: The Executive may terminate his employment for Good
Reason at any time following a Change of Control. For purposes of this
Agreement, "Good Reason" shall mean:

              (i) a substantial diminishment in the position, authority, duties
       and responsibility of the Executive, excluding for this purpose an
       isolated, insubstantial and inadvertent action not taken in bad faith and
       which is remedied by the Company promptly after receipt of notice thereof
       given by the Executive;

              (ii) any failure by the Company to comply with any of the
       provisions of Sections 3 and 5 of this Agreement, other than a failure
       not occurring in bad faith and which is remedied by the Company promptly
       after receipt of written notice thereof given by the Executive;

              (iii) the Company's requiring the Executive to be based at a
       location that is more than 40 miles away from his residence as of
       immediately prior to the Change of Control;

              (iv) any purported termination by the Company of the Executive's
       employment otherwise than as expressly permitted by this Agreement; or

              (v) any failure by the Company to comply with and satisfy Section
       10.6 of this Agreement.

       In the event of such termination, all compensation and other benefits
payable or provided hereunder shall cease as of the date of termination and Base
Salary, unpaid Bonus from a prior year, and all accrued benefits (if any) then
payable to the Executive pursuant to the terms of any plans or arrangements
referred to in Sections 3 or 5, shall be paid to the Executive through the date
of termination. No Bonus shall be payable with respect to the year in which the
Executive is terminated other than for Cause. As additional compensation for
such termination, the Company shall pay the Executive upon such termination a
lump sum equal to one year's Base Salary as is in effect as of immediately prior
to such termination. In addition, any Option Shares that are unvested as of the
date of termination shall immediately vest and become exercisable as of the
effective date of termination. The Option shall be exercisable with respect to
such accelerated shares and any other Option Shares previously vested as of the
effective date of termination and shall remain exercisable for 90 days from the
effective date of termination.

<PAGE>   8

       Any termination by the Executive for Good Reason, shall be communicated
by notice of termination to the Company indicating the specific termination
provision in this Agreement relied upon, and, to the extent applicable,
reasonable detail as to the facts and circumstances claimed to provide a basis
for termination under the provision so indicated and specifying the termination
date (which date shall be not more than thirty days after the giving of such
notice).

       (b) OTHER THAN FOR GOOD REASON. Notwithstanding any other provision of
this Agreement, the Executive may terminate his employment effective as of the
date of his written notice of termination delivered to the Board of Directors.
In the event of such termination, all compensation and other benefits payable or
provided hereunder shall cease as of the date of termination and Base Salary and
all accrued benefits (if any) then payable to the Executive pursuant to the
terms of any plans or arrangements referred to in Sections 3 or 5, shall be paid
to the Executive through the date of termination. No Bonus shall be payable with
respect to the year in which the Executive effects such termination. Upon such
termination by the Executive, the Option shall terminate immediately and shall
no longer be exercisable.

       8. CERTAIN COVENANTS OF THE EXECUTIVE.

       8.1 At all times during the Term, and following termination of this
Agreement for any reason, the Executive shall keep secret and retain in
strictest confidence, and shall not use for the benefit of himself or others
except in connection with the business and affairs of the Company, all
confidential matters relating to the business of the Company or matters relating
to this Agreement, learned by the Executive heretofore or hereafter, and shall
not disclose them to anyone outside of the Company, except (i) as required in
the course of performing his duties hereunder, (ii) with the Company's express
written consent, or (iii) to the extent that the confidential matter (a) is in
the public domain or is generally known in the industry through no unlawful act
of the Executive or (b) must be disclosed by the Executive pursuant to law.

       8.2 All memoranda, notes, lists, records and other documents or papers
made or compiled by or on behalf of the Executive, or made available to the
Executive in connection with his employment are and shall be the property of the
Company and shall be delivered to the Company promptly upon termination of the
Executive's employment with the Company or at any other time upon request.

       8.3 The Executive agrees that during the Term and for a period of one
year from the date of termination of this Agreement for reason other than
termination by the Company without Cause or termination by Executive for Good
Reason, he will not, either within or without the United States, directly or
indirectly, as a stockholder, partner, investor, director, officer, employee,
consultant, contractor, agent or in any other capacity, engage in any business
that is in competition with the Business of the Company. "Business" shall mean
the business of providing mediation software and hardware, telecommunications
data warehousing and analysis systems, billing systems or billing service bureau
for telecommunications and internet carriers, including Integrated Services
Providers (.e.g., CLECs, ILECs, RBOCS, ISPs, PTTs) or system accounting software
for enterprises and government telephony and data networks. Provided that the
foregoing shall not prohibit the Executive from owning beneficially less than 5%
of the outstanding stock of any class of stock of a corporation the securities
of which are regularly traded or quoted on a national securities exchange and
the foregoing shall not prohibit Executive from performing services as a
director, officer, employee, consultant, contractor, agent or in any other
capacity, if such services are performed for a company with multiple lines of
business and such services are not for the line of business that is in
competition with the Company's Business. Specifically, but without limiting the
generality of the foregoing, the Executive shall not directly or indirectly:

       e)  Contract with, represent, solicit business or engage in the Business
       to develop, market or sell billing data collection or network management
       systems or services;

       f)  Solicit business or in any other way interfere with or disrupt the
       Company's business relationships with any persons in the Business;

<PAGE>   9

       g)  Except as otherwise set forth below, solicit, hire, contract with or
       enter into any business dealings with, entice or aid or cooperate with
       others in soliciting or enticing any current or future employees of the
       Company to leave the Company and join any other company in the Business;

       h)  Divulge any confidential information regarding the Company to anyone
       not connected with the Company;

       "Indirect" competition shall include any competition undertaken through
an entity owned in whole or in part by the Executive or any of his agents or
affiliates.

       For a period of one year from the date of termination of this Agreement,
as a result of termination of employment or expiration of the Term, the
Executive shall not directly or indirectly, (a) solicit or encourage any
employee of the Company to leave such employment, or (b) hire any such employee
who has left such employment within one year of the termination of such
employment without the prior written agreement of the Company.

       8.4 If the Executive breaches, or threatens to breach, any of the
provisions of Section 8 (the "Restrictive Covenants"), the Company shall have,
in addition to its right immediately to terminate this Agreement for Cause, the
right and remedy (which right and remedy shall be independent of others and
severally enforceable, and which shall be in addition to, and not in lieu of,
any other rights and remedies available to the Company under law or in equity)
to seek an injunction or other equitable relief to prevent any such breach or
continuing breach, including having the Restrictive Covenants specifically
enforced by any court having equity jurisdiction, it being acknowledged and
agreed that any such breach or threatened breach will cause irreparable injury
to the Company and that money damages will not provide adequate remedy to the
Company.

       8.5 SEVERABILITY OF COVENANTS: The Executive acknowledges and agrees that
the Restrictive Covenants are reasonable and valid in all respects. If any court
determines that any of the Restrictive Covenants or any part thereof, is invalid
or unenforceable, the remainder of the Restrictive Covenants shall not thereby
be affected and shall be given full effect, without regard to the invalid
portions. The parties agree that such court shall be empowered to substitute, to
the extent enforceable, provisions similar hereto or other provisions so as to
provide to the Company, to the fullest extent possible under applicable law, the
benefits intended by this Agreement. The validity, legality or enforceability of
this Agreement shall not be affected by any such modification.

       8.6 ENFORCEABILITY IN JURISDICTIONS: The parties intend to and hereby
confer jurisdiction to enforce the Restrictive Covenants upon the courts of
Maryland.

                   NON-QUALIFIED STOCK OPTION GRANT AGREEMENT

This Amended and Restated Omnibus Stock Plan Non-Qualified Stock Option Grant
Agreement (the "Agreement") amends and restates the Non-Qualified Stock Option
Grant Agreement dated as of August 24, 1999 (the "Grant Date") entered into, by
and between ACE*COMM Corporation, a Maryland corporation (the "Company"), and
Joseph Dorr ("Grantee").

                                    ARTICLE 1

                                 GRANT OF OPTION

       SECTION 1.1 GRANT OF OPTION. Subject to the terms and conditions
prescribed in the Agreement and pursuant to the provisions of the Amended and
Restated Omnibus Stock Plan (the "Plan"), the Company hereby grants to Grantee
as of the Grant Date a Non-Qualified Stock Option (the "Option") to purchase all
or any part of 90,000 shares of voting common stock of the Company (the "Stock")
at an exercise price of $3.938 per share (the "Exercise Price").

       SECTION 1.2 TERM OF OPTION. Unless the Option granted pursuant to Section
1.1 hereof terminates earlier pursuant to other provisions of the Agreement, the
Option shall expire at 5:00 p.m. Eastern Time on the day following the tenth

                                    ARTICLE 2

                                     VESTING

                               EXERCISE OF OPTION

       SECTION 3.1 EXERCISABILITY OF OPTION. The Option shall be exercisable
with respect to any vested shares. Except as otherwise provided herein, no
portion of the Option shall be exercisable by

<PAGE>   14

Grantee prior to the time such portion of the Option has vested. Vested Option
Shares that have become exercisable shall remain exercisable throughout the term
of this Option, except as otherwise set forth in this Agreement, including
Article 4.

       SECTION 3.2 ACCELERATION OF EXERCISABILITY. Unless the Option has earlier
terminated pursuant to the provisions of the Agreement, the exercisability of
the Option granted to Grantee hereunder shall be accelerated so that the Vested
Option Shares shall become exercisable earlier in whole or in part upon the
terms and conditions set forth in the Employment Agreement dated as of October
1, 1999 between the Company and Mr. Dorr (the "Employment Agreement").

       SECTION 3.3 MANNER OF EXERCISE. The exercisable portion of the Option
shares may be exercised, in whole or in part, by delivering written notice to
the Compensation Committee of the Board of Directors in accordance with Section
5.8 hereof in such form as the Committee may require from time to time;
provided, however, that the Option may not be exercised at any one time as to
fewer than one hundred (100) shares (or such number of shares as to which the
Option is then exercisable if such number of shares then exercisable is less
than one hundred (100)). Such notice shall specify the number of shares of Stock
subject to the Option as to which the Option is being exercised, and shall be
accompanied by full payment of the Exercise Price of the shares of Stock as to
which the Option is being exercised and any applicable withholding taxes which
may be due. Payment of the Exercise Price and any withholding tax obligations
shall be made in cash (or cash equivalents acceptable to the Committee in the
Committee's discretion). In the Committee's sole and absolute discretion, the
Committee may authorize payment of the Exercise Price and any withholding tax
obligations to be made, in whole or in part, by such other means as the
Committee may prescribe. The Option may be exercised only in multiples of whole
shares and no partial shares shall be issued.

       The Committee, subject to such limitations as it may determine, may
authorize payment of the Exercise Price and any withholding tax obligations in
whole or in part, by delivery of a properly executed exercise notice, together
with irrevocable instructions: (i) to a brokerage firm approved by the Company
to deliver promptly to the Company the aggregate amount of sale or loan proceeds
to pay the exercise price and any withholding tax obligations that may arise in
connection with the exercise, and (ii) to the Company to deliver the
certificates for such purchased shares directly to such brokerage firm.

       SECTION 3.4 ISSUANCE OF SHARES AND PAYMENT OF CASH UPON EXERCISE. Upon
exercise of the Option, in whole or in part, in accordance with the terms of the
Agreement and upon payment of the Exercise Price and any withholding tax
obligations for the shares of Stock as to which the Option is exercised, the
Company shall issue to Grantee or Grantee's permitted transferee, as the case
may be, the number of shares of Stock so paid for, in the form of fully paid and
nonassessable Stock.

                                    ARTICLE 4

                              TERMINATION OF OPTION

       Unless the Option has earlier terminated pursuant to the provisions of
the Agreement, the Option granted to Grantee shall terminate in its entirety
upon the events and on the terms and conditions set forth in the Employment
Agreement, but in any event not later than on the tenth anniversary of the Grant
Date.

                                    ARTICLE 5

                                  MISCELLANEOUS

       SECTION 5.1 NON-GUARANTEE OF EMPLOYMENT OR OTHER RELATIONSHIP. Nothing in
the Plan or the Agreement shall be construed as a contract of employment or for
services between the Company (or an affiliate) and Grantee, or as a contractual
right of Grantee to continued employment or affiliation with the Company or an
affiliate, or as a limitation of the right of the Company or an affiliate to
terminate its relationship with Grantee at any time.

       SECTION 5.2 NO RIGHTS OF STOCKHOLDER. Grantee shall not have any of the
rights of a stockholder with respect to the shares of Stock that may be issued
upon the exercise of the Option until such shares of Stock have been issued to
him upon the due exercise of the Option.

       SECTION 5.3 WITHHOLDING OF TAXES. The Company or any affiliate shall have
the right to deduct from any compensation or any other payment of any kind
(including withholding the issuance of shares of Stock) due Grantee the amount
of any federal, state or local taxes required by law to be withheld as the
result of the exercise of the Option; provided, however, that the value of the
shares of Stock withheld may not exceed the statutory minimum withholding amount
required by law. In lieu of such deduction, the Committee may require Grantee to
make a cash payment to the Company or an affiliate equal to the amount required
to be withheld. If Grantee does not make such payment when requested, the
Company may refuse to issue any Stock certificate under the Plan until
arrangements satisfactory to the Committee for such payment have been made.

       SECTION 5.4 NONTRANSFERABILITY OF OPTION. Except as expressly authorized
by the Committee in writing, the Option shall be nontransferable otherwise than
by will or the laws of descent and distribution, and during the lifetime of
Grantee, the Option may be exercised only by Grantee or, during the period
Grantee is under a legal disability, by Grantee's guardian or legal
representative.

       SECTION 5.5 AGREEMENT SUBJECT TO CHARTER, BY-LAWS AND GOVERNING LAWS.
This Agreement is subject to the Charter and By-Laws of the Company, and any
applicable Federal or state laws, rules or regulations, including without
limitation, the laws, rules, and regulations of the State of Maryland, other
than the conflict of laws principles thereof.

       SECTION 5.6 GENDER. As used herein the masculine shall include the
feminine as the circumstances may require.

       SECTION 5.7 HEADINGS. The headings in the Agreement are for reference
purposes only and shall not affect the meaning or interpretation of the
Agreement.

       SECTION 5.8 NOTICES. All notices and other communications made or given
pursuant to the Agreement shall be in writing and shall be sufficiently made or
given if hand delivered or mailed by certified mail, addressed to Grantee at the
address contained in the records of the Company, or addressed to the Committee,
care of the Company for the attention of its Secretary at its principal office
or, if the receiving party consents in advance, transmitted and received via
telecopy or via such other electronic transmission mechanism as may be available
to the parties.

       SECTION 5.9 ENTIRE AGREEMENT; MODIFICATION. The Agreement contains the
entire agreement between the parties with respect to the subject matter
contained herein and may not be modified, except as provided in the Plan or in a
written document signed by each of the parties hereto.

       SECTION 5.10 CONFORMITY WITH PLAN. This Agreement is intended to conform
in all respects with, and is subject to all applicable provisions of, the Plan,
which is incorporated herein by reference. Unless stated otherwise herein,
capitalized terms in this Agreement shall have the same meaning as defined in
the Plan. Inconsistencies between this Agreement and the Plan shall be resolved
in accordance with the terms of the Plan. In the event of any ambiguity in the
Agreement or any matters as to which the Agreement is silent, the Plan shall
govern, as interpreted by the Committee in good faith.

       IN WITNESS WHEREOF, the parties have executed the Agreement as of the
date first above written.

                               EXERCISE OF OPTION

       SECTION 3.1 EXERCISABILITY OF OPTION. The Option shall be exercisable
with respect to any vested shares. Except as otherwise provided herein, no
portion of the Option shall be exercisable by Grantee prior to the time such
portion of the Option has vested. Vested Option Shares that have become

       SECTION 3.2 ACCELERATION OF EXERCISABILITY. Unless the Option has earlier

       SECTION 3.3 MANNER OF EXERCISE. The exercisable portion of the Option

provided, however, that the Option may not be exercised at any one time as to
fewer than one hundred (100) shares (or such number of shares as to which the
Option is then exercisable if such number of shares then exercisable is less
than one hundred (100)). Such notice shall specify the number of shares of Stock
subject to the Option as to which the Option is being exercised, and shall be
accompanied by full payment of the Exercise Price of the shares of Stock as to
which the Option is being exercised and any applicable withholding taxes which
may be due. Payment of the Exercise Price and any withholding tax obligations
shall be made in cash (or cash equivalents acceptable to the Committee in the
Committee's discretion). In the Committee's sole and absolute discretion, the
Committee may authorize payment of the Exercise Price and any withholding tax
obligations to be made, in whole or in part, by such other means as the
Committee may prescribe. The Option may be exercised only in multiples of whole
shares and no partial shares shall be issued.

       The Committee, subject to such limitations as it may determine, may
authorize payment of the Exercise Price and any withholding tax obligations in
whole or in part, by delivery of a properly executed exercise notice, together
with irrevocable instructions: (i) to a brokerage firm approved by the Company
to deliver promptly to the Company the aggregate amount of sale or loan proceeds
to pay the exercise price and any withholding tax obligations that may arise in
connection with the exercise, and (ii) to the Company to deliver the
certificates for such purchased shares directly to such brokerage firm.

       SECTION 3.4 ISSUANCE OF SHARES AND PAYMENT OF CASH UPON EXERCISE. Upon
exercise of the Option, in whole or in part, in accordance with the terms of the
Agreement and upon payment of the Exercise Price and any withholding tax
obligations for the shares of Stock as to which the Option is exercised, the
Company shall issue to Grantee or Grantee's permitted transferee, as the case
may be, the number of shares of Stock so paid for, in the form of fully paid and
nonassessable Stock.

                                  MISCELLANEOUS

       SECTION 5.1 NON-GUARANTEE OF EMPLOYMENT OR OTHER RELATIONSHIP. Nothing in
the Plan or the Agreement shall be construed as a contract of employment or for
services between the Company (or an affiliate) and Grantee, or as a contractual
right of Grantee to continued employment or affiliation with the Company or an
affiliate, or as a limitation of the right of the Company or an affiliate to
terminate its relationship with Grantee at any time.

       SECTION 5.2 NO RIGHTS OF STOCKHOLDER. Grantee shall not have any of the
rights of a stockholder with respect to the shares of Stock that may be issued
upon the exercise of the Option until such shares of Stock have been issued to
him upon the due exercise of the Option.

       SECTION 5.3 WITHHOLDING OF TAXES. The Company or any affiliate shall have
the right to deduct from any compensation or any other payment of any kind
(including withholding the issuance of shares of Stock) due Grantee the amount
of any federal, state or local taxes required by law to be withheld as the
result of the exercise of the Option; provided, however, that the value of the
shares of Stock withheld may not exceed the statutory minimum withholding amount
required by law. In lieu of such deduction, the Committee may require Grantee to
make a cash payment to the Company or an affiliate equal to the amount required
to be withheld. If Grantee does not make such payment when requested, the
Company may refuse to issue any Stock certificate under the Plan until
arrangements satisfactory to the Committee for such payment have been made.

       SECTION 5.4 NONTRANSFERABILITY OF OPTION. Except as expressly authorized
by the Committee in writing, the Option shall be nontransferable otherwise than
by will or the laws of descent and distribution, and during the lifetime of
Grantee, the Option may be exercised only by Grantee or, during the period
Grantee is under a legal disability, by Grantee's guardian or legal
representative.

       SECTION 5.5 AGREEMENT SUBJECT TO CHARTER, BY-LAWS AND GOVERNING LAWS.
This Agreement is subject to the Charter and By-Laws of the Company, and any
applicable Federal or state laws, rules or regulations, including without
limitation, the laws, rules, and regulations of the State of Maryland, other
than the conflict of laws principles thereof.

       SECTION 5.6 GENDER. As used herein the masculine shall include the
feminine as the circumstances may require.

       SECTION 5.7 HEADINGS. The headings in the Agreement are for reference
purposes only and shall not affect the meaning or interpretation of the
Agreement.

       SECTION 5.8 NOTICES. All notices and other communications made or given
pursuant to the Agreement shall be in writing and shall be sufficiently made or
given if hand delivered or mailed by certified mail, addressed to Grantee at the
address contained in the records of the Company, or addressed to the Committee,
care of the Company for the attention of its Secretary at its principal office
or, if the receiving party consents in advance, transmitted and received via
telecopy or via such other electronic transmission mechanism as may be available
to the parties.

entire agreement between the parties with respect to the subject matter
contained herein and may not be modified, except as provided in the Plan or in a
written document signed by each of the parties hereto.

       SECTION 5.10 CONFORMITY WITH PLAN. This Agreement is intended to conform
in all respects with, and is subject to all applicable provisions of, the Plan,
which is incorporated herein by reference. Unless stated otherwise herein,
capitalized terms in this Agreement shall have the same meaning as defined in
the Plan. Inconsistencies between this Agreement and the Plan shall be resolved
in accordance with the terms of the Plan. In the event of any ambiguity in the
Agreement or any matters as to which the Agreement is silent, the Plan shall
govern, as interpreted by the Committee in good faith.

       IN WITNESS WHEREOF, the parties have executed the Agreement as of the
date first above written.
