     2. Principal and Interest.

     (a) The Company shall pay interest to the Holder on the then outstanding principal amount of
this Note at a rate of 11.25% per annum, as the same may be adjusted from time to time pursuant to
the terms hereof (the “Interest Rate”). The Interest Rate shall be reduced from time to time by
100 basis points (1.0%) for each Interest Rate Adjustment Event (if any), as of the date of that
Interest Rate Adjustment Event, but in no event below zero, provided that the Equity Conditions are
satisfied on, and at all times during the sixty day period preceding, the applicable Interest
Payment Date. The Interest Rate reductions shall be reversed if the Current Market Price at any
time after a reduction in the Interest Rate is less than the product of the Conversion Price
multiplied by the Factor. Interest shall be payable monthly in arrears (each, a “Monthly Interest
Payment”) in cash on the last day of each month, except if such date is not a Trading Day in which
case such interest shall be payable on the next succeeding Trading Day (each, an “Interest Payment
Date”); provided, that the Company may elect to pay any Monthly
Interest Payment by issuing shares of Common Stock if (i) the Company would be permitted on
such Interest Payment Date to pay a Monthly Installment by issuing shares of Common Stock without
exceeding the Monthly Installment Volume Limitation and (ii) the Company confirms to the Holder in
writing concurrently with such issuance that the Company does not believe that the Holder, or any
employee, officer, director, agent or representative of the Holder, has been provided any material
non-public information relating to the Company by the Company or any Subsidiary, or any of their
respective employees, officers, directors, agents or representatives (provided,
further, that the Company shall notify the Holder in writing within three (3) Trading Days
prior to such Interest Payment Date if the Company is not able to make such confirmation, and in
such event the Holder shall have the option, exercisable by written notice to the Company on or
prior to such Interest Payment Date, to either (A) defer the due date of such Monthly Interest
Payment and any unpaid previously deferred Monthly Interest Payments (except to the extent elected
to be paid in Common Stock pursuant to clause (B) below) to the next succeeding Interest Payment
Date (each such deferred Monthly Interest Payment, a “Deferred Monthly Interest Payment”) or
(B) receive such Monthly Interest Payment and/or any prior unpaid Deferred Monthly Interest
Payments (as indicated in such notice) by issuance of shares of Common Stock; if the Holder does
not deliver such written notice, then such Monthly Interest Payment shall be a Deferred Monthly
Interest Payment unless the Company pays it in cash when due). On each Interest Payment Date, all
unpaid Deferred Monthly Interest Payments shall be due and payable unless deferred to the next
succeeding Interest Payment Date in accordance with the preceding sentence. The first Interest
Payment Date shall be June 30, 2007. Subject to the limitations set forth in Section 6(c)
below, the Holder may, upon written notice to the Company not less than 10 Trading Days prior to an
Interest Payment Date, require the Company to pay such interest payable on such Interest Payment
Date in shares of Common Stock in accordance with Section 2(d) below. During the pendancy
of any Event of Default , the Interest Rate shall equal the Default Rate.

     (b) The Company shall pay the principal balance of this Note to the Holder in eighteen (18)
equal monthly installments (each, a “Monthly Installment”) commencing on December 30, 2008 (or such
later date as the Holder may, in its sole discretion, determine by written notice to the Company)
and continuing each month thereafter on the last day of each month, except if such date is not a
Trading Day in which case such Monthly Installment shall be payable on the next succeeding Trading
Day (each, a “Principal Payment Date”), until the outstanding principal balance of this Note has
been paid in full, provided, however, that, in the event that the Company is not
permitted pursuant to Section 2(c) below to pay such Monthly Installment by issuing shares of
Common Stock because of the Monthly Installment Volume Limitation (but would otherwise be entitled
pursuant to Section 2(c) below to do so), the Company may elect, by written notice to the Holder (a
“Deferral Notice”), to pay by issuance of Common Stock the portion of such Monthly Installment that
may be paid without exceeding the Monthly Installment Volume Limitation and, in respect of up to
four (4) Monthly Installments in any calendar year, to defer payment of the balance of such Monthly
Installment until the next Principal Payment Date (a “Deferred Monthly Installment”);
provided, further, that (i) if the Holder elects by written notice to the Company
within five (5) Business Days after receipt of a Deferral Notice to accept payment of all or part
of such Monthly Installment by issuance of Common Stock notwithstanding the Monthly Installment
Volume Limitation, the Company shall pay all or such indicated portion of such Monthly Installment
by issuance of Common Stock, and (ii) until any outstanding Deferred Monthly Installments have been
paid in full, interest shall
continue to accrue on such Deferred Monthly Installment at the Interest Rate (or Default Rate,
if applicable), and any payment (in cash or Common Stock) on this Note shall be applied first to
the repayment of the interest portion of all unpaid Deferred Monthly Installments, in the order
such Deferred Monthly Installments were deferred, and then to the repayment of the principal
portion of all unpaid Deferred Monthly Installments, in the order such Deferred Monthly
Installments were deferred, before application to other amounts owing under this Note. If the
Holder elects to convert any portion of the principal amount of this Note, that amount shall be
applied as a credit to the next succeeding Monthly Installment or Monthly Installments, as
applicable or such other Monthly Installment(s) as specified by the Holder.

7

 

     (c) Unless the Holder otherwise consents in writing, and subject to the limitations set forth
in Section 6(c) below, the Company shall pay each Monthly Installment by issuing shares of
Common Stock if (i) all of the Equity Conditions are satisfied on and at all times during the ten
(10) days preceding the applicable Principal Payment Date (or the Holder otherwise waives in
writing the Equity Conditions), and (ii) the arithmetic average of the VWAP for each of the 20
consecutive Trading Days prior to such Principal Payment Date is greater than 110% of the
Conversion Price then in effect; provided, however, that, unless and to the extent
waived by the Holder, the aggregate number of shares of Common Stock issuable by the Company to the
Holder as payment in respect of such Monthly Installment, together with any shares of Common Stock
then issuable as payment in respect of a Monthly Interest Payment (not including any unpaid
Deferred Monthly Interest Payment), shall not exceed 100% of the arithmetic average of the Daily
Trading Volume for each of the 20 consecutive Trading Days preceding such Principal Payment Date
(the “Monthly Installment Volume Limitation”). Any Monthly Installment or any portion thereof that
is not required or permitted to be paid in Common Stock pursuant to this Section 2(c) shall be paid
by the Company in cash on the applicable Principal Payment Date. In the event that the Company
pays a Monthly Installment (or any portion thereof) in cash, then the amount payable to the Holder
shall equal 102% of the Monthly Installment. Any payment of a Monthly Installment plus accrued
interest in whole or in part in shares of Common Stock shall effectively be treated as a partial
conversion of that portion of the principal amount of this Note or accrued interest, with a credit
applied against such Monthly Installment or accrued interest.

     (d) In the event that the Company pays a Monthly Installment (or any portion thereof) in
shares of Common Stock or the Holder elects to have interest paid in shares of Common Stock, the
number of shares of Common Stock to be issued to the Holder as payment for such interest or Monthly
Installment (or any portion thereof) shall be (i) with respect to interest, determined by dividing
the aggregate amount of interest payable to the Holder by the Market Price (as defined below) as of
the applicable Interest Payment Date, and rounding up to the nearest whole share, (ii) with respect
to a Monthly Installment, determined by dividing the Monthly Installment (or any portion thereof)
by the Conversion Price (as adjusted in accordance herewith) and rounding up to the nearest whole
share, and (iii) paid to the Holder in accordance with Section 2(e) below. The term
“Market Price” shall mean 93% of the arithmetic average of the VWAP for each of the 20 consecutive
Trading Days prior to the applicable Principal Payment Date (not including such date).

8

 

     (e) In the event that any interest or a Monthly Installment (or any portion thereof) is paid
in Common Stock, the Company shall on such Interest Payment Date or Principal Payment Date, as
applicable, (i) issue (or cause to be issued) and deliver (or cause to be delivered) to the
Holder a certificate, bearing the restrictive legends set forth herein, registered in the name
of the Holder, for the number of shares of Common Stock to which the Holder shall be entitled, or
(ii) at all times after (x) the Company is eligible to deliver its Common Stock electronically
through The Depository Trust Company (the “DTC”) in connection with a resale by the Holder of such
shares pursuant to the Registration Statement and (y) the Holder has notified the Company that this
clause (ii) shall apply, credit the number of shares of Common Stock to which the Holder shall be
entitled to the Holder’s or its designee’s balance account with the DTC through its Deposit
Withdrawal Agent Commission System.

     (f) Notwithstanding the foregoing, the Holder may elect to defer (i) any Monthly Installment
prior to its Principal Payment Date and/or (ii) any interest payment prior to its Interest Payment
Date. If the Holder elects to defer a Monthly Installment and/or an interest payment, the Company
shall pay such deferred Monthly Installment and/or interest payment (together with all other
amounts that may be due and payable by the Company) on the Maturity Date or such earlier date as
the Holder may otherwise elect in writing (but not prior to the Principal Payment Date or, if
applicable, the Interest Payment Date, when it was otherwise due). If the Holder elects to defer a
Monthly Installment and/or an interest payment, no interest shall accrue on any such deferred
amounts.

     (g) This Note may not be prepaid in whole or in part absent the consent of the Majority
Holders.

     3. Ranking and Covenants.

     (a) Except as permitted in Section 4.10(a) of the Purchase Agreement, (i) no Indebtedness of
the Company is senior to or on a parity with this Note in right of payment, whether with respect to

issuance of Common Stock pursuant to the definition of Excluded Stock), or (iii) without prejudice
to the rights of Holder pursuant to Section 4.13 of the Purchase Agreement or in respect of a

(A) the aggregate amount of such Indebtedness or Subsequent Placement or proceeds of such Major
Asset Sale, and (B) the aggregate amount required to repurchase this entire Note pursuant to this
Section 3(c). All Notes repurchased under this Section 3(c) shall be repurchased

     (i) If any of the Accounts (i) exceeding $100,000 or (ii) if the Holder requests such notice
or action, exceeding $25,000, arises out of a contract with a U.S. Agency, the Company shall
promptly notify Agent thereof in writing and shall execute any instruments, send any notices and
take any other action required, or requested by Agent, to comply with the provisions of the Federal
Assignment of Claims Act.

10

 

     (j) The Company shall not, at all times when any Note is outstanding:

     (i) Accelerate any payments which are not currently due under any maintenance, license
or any other agreement or contract with any customer;

     (ii) Enter into any maintenance agreement or maintenance contract with a term of
greater than one (1) year, other than a maintenance agreement or maintenance contract
providing for maintenance payments not less frequently than annually and pursuant to which
such maintenance payments are pro rata over the term of the contract;

     (iii) Renew any maintenance, license or other agreement or contract that is not within
three (3) months, for domestic contracts, and within four (4) months, for international
contracts, of the expiration date for the license or services contained in such agreement;

     (iv) Renew or reinstate any maintenance, license or other agreement that has expired
for an amount less than the annual amount of maintenance or other payable during the last
period such agreement was in effect for items to be covered under the new maintenance
contract.

     4. Registration of Notes. The Company shall register the Notes upon records to be
maintained by the Company for that purpose (the “Note Register”) in the name of each record holder
thereof from time to time. The Company may deem and treat the registered Holder of this Note as
the absolute owner hereof for the purpose of any conversion hereof or any payment of interest or
principal hereon, and for all other purposes, absent actual notice to the contrary.

     5. Registration of Transfers and Exchanges. This Note and all rights hereunder are
transferable in whole or in part upon the books of the Company by the Holder hereof; provided,
however, that the transferee shall agree in writing to be bound by the terms and subject to the
conditions of this Note and the Purchase Agreement. The Company shall register the transfer of any
portion of this Note in the Note Register upon surrender of this Note to the Company at its address
for notice set forth herein. Upon any such registration or transfer, a new Note, in substantially
the form of this Note (any such new Note, a “New Note”), evidencing the portion of this Note so
transferred shall be issued to the transferee and a New Note evidencing the remaining portion of
this Note not so transferred, if any, shall be issued to the transferring Holder. The acceptance
of the New Note by the transferee thereof shall be deemed the acceptance by such transferee of all
of the rights and obligations of a holder of a Note. This Note is exchangeable for an equal
aggregate principal amount of Notes of different authorized denominations, as requested by the
Holder surrendering the same. No service charge or other fee will be imposed in connection with
any such registration of transfer or exchange.

11

 

     6. Conversion.

     (a) At the Option of the Holder. All or any portion of this Note shall be convertible
into shares of Common Stock (subject to the limitations set forth in Section 6(c)), at the
option of the Holder, at any time and from time to time from and after the Original Issue Date.
The number of Underlying Shares issuable upon any conversion hereunder shall equal the outstanding
principal amount of this Note to be converted, plus the amount of any accrued but
unpaid interest on this Note through the Conversion Date, divided by the Conversion Price on
the Conversion Date. The Holder shall effect conversions under this Section 6(c) by
delivering to the Company a Conversion Notice together with a schedule in the form of Schedule
2 attached hereto (the “Conversion Schedule”). If the Holder is converting less than all of
the principal amount of this Note, or if a conversion hereunder may not be effected in full due to
the application of Section 6(c), the Company shall honor such conversion to the extent
permissible hereunder and shall promptly deliver to the Holder a Conversion Schedule indicating the
principal amount (and accrued interest) which has not been converted.

     (b) At the Option of the Company. If at any time (i) the Market Price is 200%
greater than the Conversion Price then in effect for at least sixty-five (65) consecutive Trading
Days, and (ii) the Equity Conditions are satisfied for such sixty-five (65) consecutive Trading Day
period and through the Conversion Date, then the Company may elect to require the Holders to
convert a portion of the outstanding principal amount of this Note, up to its entirety, into Common
Stock by delivering an irrevocable written notice of such election to the Holders. The amount of
principal amount of this Note convertible as provided in the preceding sentence shall be limited to
the amount that is convertible into a number of shares of Common Stock which, together with all
other shares of Common Stock received upon conversion of all Notes in the 30-day period preceding
the applicable Conversion Date, does not exceed the arithmetic average of the Daily Trading Volume
for each of the 20 consecutive Trading Days preceding that Conversion Date. The tenth (10th)
Trading Day after the delivery of such notice will be the “Conversion Date” for such required
conversion. For purposes of example only, if the Conversion Price is $1.00, then the Market Price
would need to be greater than $3.00 during the relevant period for the condition set forth Section
6(b)(i) to be satisfied.

     (c) Certain Conversion Restrictions.

     (i) Subject to Section 6(c)(ii), the number of shares of Common Stock that may be
acquired by a Holder upon any conversion of Notes (or otherwise in respect hereof) shall be
limited to the extent necessary to insure that, following such conversion (or other
issuance), the total number of shares of Common Stock then beneficially owned by such Holder
and its Affiliates and any other Persons whose beneficial ownership of Common Stock would be
aggregated with such Holder’s for purposes of Section 13(d) of the Exchange Act, does not
exceed 4.999% of the total number of issued and outstanding shares of Common Stock
(including for such purpose the shares of Common Stock issuable upon such conversion), (the
“Threshold Percentage”). For such purposes, beneficial ownership shall be determined in
accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated
thereunder.

     (ii) Notwithstanding the provisions of Section 6(c)(i), the Holder shall have the right
at any time and from time to time, to waive the provisions of this Section insofar as they
relate to the Threshold Percentage or to increase its Threshold Percentage (but not in
excess of 9.999% (or such lower percentage if Section 16 of the Exchange Act or the rules
promulgated thereunder (or any successor statute or rules) is changed to reduce the
beneficial ownership percentage threshold thereunder to a percentage less than 9.999%)) by
written instrument delivered to the Company, but (i) any such waiver or increase will not be
effective until the 61st day after such notice is delivered to the
Company, and (ii) any such waiver or increase or decrease will apply only to the Holder
and not to any other holder of Notes.

12

 

     7. Mechanics of Conversion; Restrictive Legends.

     (a) Upon conversion of this Note, the Company shall promptly (but in no event later than three
Trading Days after the Conversion Date) issue or cause to be issued and cause to be delivered to or
upon the written order of the Holder and in such name or names as the Holder may designate a
certificate for the Underlying Shares issuable upon such conversion. The Holder, or any Person so
designated by the Holder to receive Underlying Shares, shall be deemed to have become holder of
record of such Underlying Shares as of the Conversion Date. The Company shall, upon request of the
Holder, use its reasonable best efforts to deliver the Underlying Shares hereunder electronically
through the DTC in connection with a resale by the Holder of such shares pursuant to the
Registration Statement.

     (b) The Holder shall not be required to deliver the original Note in order to effect a
conversion hereunder. Execution and delivery of the Conversion Notice shall have the same effect
as cancellation of the original Note and issuance of a New Note representing the remaining
outstanding principal amount; provided that the cancellation of the original Note shall not
be deemed effective until a certificate for such Underlying Shares is delivered to the Holder, or
the Holder or its designee receives a credit for such Underlying Shares to its balance account with
the DTC through its Deposit Withdrawal Agent Commission System. Upon surrender of this Note
following one or more partial conversions, the Company shall promptly deliver to the Holder a New
Note representing the remaining outstanding principal amount. The Holder shall deliver the
original Note to the Company within thirty (30) days after the conversion of the entire Note
hereunder, provided, that the Holder’s failure to so deliver the original Note shall not
affect the validity of such conversion or any of the Company’s obligations under this Note, and the
Company’s sold remedy for the Holder’s failure to deliver the original Note shall be to obtain an
affidavit of lost note from the Holder.

     (c) The Company’s obligations to issue and deliver Underlying Shares upon conversion of this
Note in accordance with the terms and subject to the conditions hereof are absolute and
unconditional, irrespective of any action or inaction by the Holder to enforce the same, any waiver
or consent with respect to any provision hereof, the recovery of any judgment against any Person or
any action to enforce the same, or any set-off, counterclaim, recoupment, limitation or
termination, or any breach or alleged breach by the Holder or any other Person of any obligation to
the Company or any violation or alleged violation of law by the Holder or any other Person, and
irrespective of any other circumstance which might otherwise limit such obligation of the Company
to the Holder in connection with the issuance of such Underlying Shares (other than such
limitations contemplated by this Note).

     (d) If by the fifth Trading Day after a Conversion Date the Company fails to deliver or cause
to be delivered to the Holder such Underlying Shares in such amounts and in the manner required
pursuant to Section 7(a), then the Holder will have the right to rescind such conversion.

13

 

     (e) If by the third Trading Day after a Conversion Date the Company fails to deliver or cause
to be delivered to the Holder such Underlying Shares in such amounts and in the manner required
pursuant to Section 7(a), and if after such third Trading Day the Holder purchases (in an
open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale
by the Holder of the Underlying Shares which the Holder anticipated receiving upon such conversion
(a “Buy-In”), then the Company shall either (i) pay cash to the Holder (in addition to any other
remedies available to or elected by the Holder) in an amount equal to the Holder’s total purchase
price (including brokerage commissions, if any) for the shares of Common Stock so purchased (the
“Buy-In Price”), at which point the Company’s obligation to deliver such certificate (and to issue
such Common Stock) shall terminate, or (ii) promptly honor its obligation to deliver to the Holder
a certificate or certificates representing such Common Stock and pay cash to the Holder in an
amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of
shares of Common Stock, times (B) the Closing Price on the date of the event giving rise to the
Company’s obligation to deliver such certificate.

     (f) Each certificate for Underlying Shares shall bear a restrictive legend to the extent and
as provided in the Purchase Agreement and any certificate issued at any time in exchange or
substitution for any certificate bearing such legend, shall also bear such legend, unless, in the
opinion of counsel for the holder thereof (which opinion shall be reasonably satisfactory to
counsel for the Company), the securities represented thereby are not, at such time, required by law
to bear such legend.

     8. Redemption.

     (a) At any time following the 90th Trading Day following the Original Issue Date, the Company
shall have the right to repurchase (an “Optional Redemption”) all (but not some only) of the Notes
then outstanding at a price equal to 125% of principal and all accrued but unpaid interest due
under such Notes (the “Optional Redemption Price”), in cash, provided, that if the
aggregate value of the Underlying Shares for which all of the Notes may then be converted (based on
the arithmetic average of the Closing Prices on the most recent ten (10) Trading Days prior to the
proposed Optional Redemption) exceeds the Optional Redemption Price, then the Company shall have
the right to effect the Optional Redemption only if (i) all of the Equity Conditions are satisfied
on and at all times during the twenty (20) days preceding the date of the proposed Optional
Redemption and (ii) the aggregate number of Underlying Shares issuable on such date does not exceed
100% of the arithmetic average of the Daily Trading Volume for each of the 20 consecutive Trading
Days preceding the date of the proposed Optional Redemption. To effect an Optional Redemption the
Company must deliver a notice of the Optional Redemption to the Holders at least twenty (10)
Trading Days prior the date of the Optional Redemption (the “Optional Redemption Date”), which
notice shall state the date of the Optional Redemption Date and the Optional Redemption Price.

     (b) Upon receipt of payment of the Optional Redemption Price by the Holders of Notes, each
Holder will deliver the certificate(s) evidencing the Notes redeemed by the Company against payment
of the Optional Redemption Price therefor, unless such Holder is awaiting receipt of a new
certificate evidencing such shares from the Company pursuant to another provision hereof. At any
time on or prior to the Optional Redemption Date, the Holder may
convert all or any portion of this Note, and the Company shall honor any such conversions in
accordance with the terms hereof.

14

 

     9. Events of Default.

     (a) “Event of Default” means any one of the following events (whatever the reason and whether
it shall be voluntary or involuntary or effected by operation of law or pursuant to any judgment,
decree or order of any court, or any order, rule or regulation of any administrative or
governmental body):

          (i) any default in the payment (free of any claim of subordination) of principal,
interest or liquidated damages in respect of any Notes, as and when the same becomes due and
payable (whether on a date specified for the payment of interest or the date on which the
obligations under the Note mature or by acceleration, redemption, prepayment or otherwise),
which default continues uncured for a period of five (5) days;

          (ii) the Company or any Significant Subsidiary defaults in any of its covenants or
other obligations in respect of (A) any Indebtedness permitted by Section 4.10(a) of the
Purchase Agreement, or (B) any other note or any mortgage, credit agreement or other
facility, indenture agreement, factoring agreement or other instrument under which there may
be issued, or by which there may be secured or evidenced, any Indebtedness for borrowed
money or money due under any long term leasing or factoring arrangement of the Company or
any Significant Subsidiary in an amount exceeding $500,000, whether such Indebtedness now
exists or is hereafter created, or any event or circumstance occurs that with notice or
lapse of time would constitute such a default, which default has not been cured;

          (iii) the Company or any Significant Subsidiary is in default under any contract or
agreement, financial or otherwise, between the Company or any Significant Subsidiary, as
applicable, and any other Person and such default involves claimed actual damages in excess
of $1,000,000 and either (A) the Company has paid or acknowledged liability for such claim
or (B) the other party thereto commences litigation or arbitration proceedings to exercise
its rights and remedies under such contract or agreement as a consequence of such default;

          (iv) there is entered against the Company or any Significant Subsidiary and not
discharged or stayed (A) a final judgment or order for the payment of money in an aggregate
amount exceeding $1,000,000, or (B) any one or more non-monetary final judgments that have,
or could reasonably be expected to have, individually or in the aggregate, a material
adverse effect on the Company or any Significant Subsidiary;

          (v) any Transaction Document, at any time after the Original Issue Date, and for any
reason other than as expressly permitted thereunder, ceases to be in full force and effect;
or the Company or any Subsidiary contests in any manner the validity or enforceability of
any Transaction Document or any provision thereof; or the Company or any Subsidiary denies
that it has any or further liability or obligation under any
Transaction Document, or purports to revoke, terminate or rescind any Transaction
Documents;

          (vi) any Security Agreement ceases to give the Agent (as defined in the Security
Agreements) the primary benefits thereof, including a perfected, enforceable first priority
security interest in, and Lien on, all of the Collateral (as defined therein);

          (vii) the occurrence of a Triggering Event; or

          (viii) the occurrence of a Bankruptcy Event.

15

 

     (b) At any time or times following the occurrence of an Event of Default, the Holder shall
have the option to elect, by notice to the Company (an “Event Notice”), to require the Company to
repurchase all or any portion of the outstanding principal amount of this Note, at a repurchase
price equal to 125% of such outstanding principal amount, plus all accrued but unpaid interest
thereon through the date of payment. The aggregate amount payable pursuant to the preceding
sentence is referred to as the “Event Price.” The Company shall pay the Event Price to the Holder
no later than the third Trading Day following the date of delivery of the Event Notice, and upon
receipt thereof the Holder shall deliver this Note and certificates evidencing any Underlying
Shares so repurchased to the Company (to the extent such certificates have been delivered to the
Holder).

     (c) Upon the occurrence of any Bankruptcy Event, all amounts pursuant to Section 9(b)
shall immediately become due and payable in full in cash, without any further action by the Holder.

     (d) In connection with any Event of Default, the Holder need not provide, and the Company
hereby waives, any presentment, demand, protest or other notice of any kind, and the Holder may
immediately and without expiration of any grace period enforce any and all of its rights and
remedies hereunder and all other remedies available to it under applicable law. Any such
declaration may be rescinded and annulled by the Holder at any time prior to payment hereunder. No
such rescission or annulment shall affect any subsequent Event of Default or impair any right
incidental thereto.

     (e) In the event that the Event Price is not paid in cash when due, then, in addition to all
other remedies that may be available, the Holder may require the Company to pay the Event Price in
shares of Common Stock of the Company, to be issued at 93% of the Current Market Price. In the
event the Holder exercises its rights under this paragraph, the Company agrees promptly to take all
actions as may be required, including without limitation seeking to obtain shareholder approval if
required, in order to comply with its obligations under this paragraph.

     10. Charges, Taxes and Expenses. Issuance of certificates for Underlying Shares upon
conversion of (or otherwise in respect of) this Note shall be made without charge to the Holder for
any issue or transfer tax, withholding tax, transfer agent fee or other incidental tax or expense
in respect of the issuance of such certificate, all of which taxes and expenses shall be paid by
the Company; provided, however, that the Company shall not be required to pay any
tax which may be payable in respect of any transfer involved in the registration of any
certificates for Underlying Shares or Notes in a name other than that of the Holder. The Holder
shall be
responsible for all other tax liability that may arise as a result of holding or transferring
this Note or receiving Underlying Shares in respect hereof.

16

 

     11. Certain Adjustments. The Conversion Price is subject to adjustment from time to
time as set forth in this Section 11.

     (a) Stock Dividends and Splits. If the Company, at any time while this Note is
outstanding, (i) pays a stock dividend on its Common Stock or otherwise makes a distribution on any
class of capital stock that is payable in shares of Common Stock, (ii) subdivides outstanding
shares of Common Stock into a larger number of shares, or (iii) combines outstanding shares of
Common Stock into a smaller number of shares, then in each such case the Conversion Price shall be
multiplied by a fraction of which the numerator shall be the number of shares of Common Stock
outstanding immediately before such event and of which the denominator shall be the number of
shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to
clause (i) of this Section 11(a) shall become effective immediately after the record date
for the determination of stockholders entitled to receive such dividend or distribution, and any
adjustment pursuant to clause (ii) or (iii) of this Section 11(a) shall become effective
immediately after the effective date of such subdivision or combination.

     (b) Pro Rata Distributions. If the Company, at any time while this Note is
outstanding, distributes to all holders of Common Stock (i) evidences of its indebtedness, (ii) any
security (other than a distribution of Common Stock described in Section 11(a)),
(iii) rights or warrants to subscribe for or purchase any security, or (iv) cash or any other asset
(in each case, “Distributed Property”), then the Company shall deliver to the Holder (on the
effective date of such distribution), the Distributed Property that the Holder would have been
entitled to receive in respect of the Underlying Shares for which this Note could have been
converted immediately prior to the date on which holders of Common Stock became entitled to receive
such Distributed Property (without giving effect to any limitation on conversion in Section
6(c)).

     (c) Fundamental Changes. If, at any time while this Note is outstanding, (i) the
Company effects any merger or consolidation of the Company with or into another Person, (ii) the
Company effects any sale of all or substantially all of its assets in one or more transactions,
(iii) any tender offer or exchange offer (whether by the Company or another Person) is completed
pursuant to which holders of Common Stock are permitted to tender or exchange their shares for
other securities, cash or property, (iv) the Company effects any reclassification of the Common
Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted
into or exchanged for other securities, cash or property (other than as a result of a subdivision
or combination of shares of Common Stock described in Section 11(a)), or (v) there is a
Change of Control (each case in clauses (i) through (v) above, a “Fundamental Change”), then upon
any subsequent conversion of this Note, the Holder shall have the right to receive (except to the
extent previously distributed to the Holder pursuant to Section 11(b)), for each Underlying
Share that would have been issuable upon such conversion absent such Fundamental Change (without
giving effect to any limitation on conversion in Section 6(c)), the same kind and amount of
securities, cash or property as it would have been entitled to receive upon the occurrence of such
Fundamental Change if it had been, immediately prior to such Fundamental Change, the holder of one
share of Common Stock (the “Alternate Consideration”). If holders of Common Stock are given any
choice as to the securities, cash or
property to be received in a Fundamental Change, then the Holder shall be given the same
choice as to the Alternate Consideration it receives upon any conversion of this Note following
such Fundamental Change. In the event of a Fundamental Change, the Company or the successor or
purchasing Person, as the case may be, shall execute with the Holder a written agreement providing
that:

     (x) this Note shall thereafter entitle the Holder to purchase the Alternate
Consideration;

17

 

     (y) in the case of any such successor or purchasing Person, upon such consolidation,
merger, statutory exchange, combination, sale or conveyance such successor or purchasing
Person shall be jointly and severally liable with the Company for the performance of all of
the Company’s obligations under this Note and the other Transaction Documents; and

     (z) if registration or qualification is required under the Exchange Act or applicable
state law for the public resale by the Holder of shares of stock and other securities so
issuable upon exercise of this Note, such registration or qualification shall be completed
prior to such reclassification, change, consolidation, merger, statutory exchange,
combination or sale.

If, in the case of any Fundamental Change, the Alternate Consideration includes shares of stock,
other securities, other property or assets of a Person other than the Company or any such successor
or purchasing Person, as the case may be, in such Fundamental Change, then such written agreement
shall also be executed by such other Person and shall contain such additional provisions to protect
the interests of the Holder as the Board of Directors of the Company shall reasonably consider
necessary by reason of the foregoing. At the Holder’s request, any successor to the Company or
surviving Person in such Fundamental Change shall issue to the Holder a new Note consistent with
the foregoing provisions and evidencing the Holder’s right to convert such Note into Alternate
Consideration. The terms of any agreement pursuant to which a Fundamental Change is effected shall
include terms requiring any such successor or surviving Person to comply with the provisions of
this Section 11(c) and insuring that this Note (or any such replacement security) will be
similarly adjusted upon any subsequent transaction analogous to a Fundamental Change. If any
Fundamental Change constitutes or results in a Change of Control, then at the request of the
Holder, the Company (or any such successor or surviving entity) will purchase this Note from the
Holder for a purchase price, payable in cash within five Trading Days after such request, equal to
the greater of (x) 125% of such outstanding principal amount, plus all accrued but unpaid interest
thereon through the date of payment, and (y) the Event Equity Value of the Underlying Shares
issuable upon conversion of such principal amount and all such accrued but unpaid interest thereon.

     (d) Subsequent Equity Sales.

          (i) If, at any time while this Note is outstanding, the Company directly or indirectly
issues additional shares of Common Stock or rights, warrants, options or other securities or
debt convertible, exercisable or exchangeable for shares of Common Stock or otherwise
entitling any Person to acquire shares of Common Stock (collectively,

18

 

“Common Stock Equivalents”) at an effective net price to the Company per share of
Common Stock (the “Effective Price”) less than the Conversion Price (as adjusted hereunder
to such date), then the Conversion Price shall be reduced to equal the Effective Price. For
purposes of this paragraph, in connection with any issuance of any Common Stock Equivalents,
(A) the maximum number of shares of Common Stock potentially issuable at any time upon
conversion, exercise or exchange of such Common Stock Equivalents (the “Deemed Number”)
shall be deemed to be outstanding upon issuance of such Common Stock Equivalents, (B) the
Effective Price applicable to such Common Stock shall equal the minimum dollar value of
consideration payable to the Company to purchase such Common Stock Equivalents and to
convert, exercise or exchange them into Common Stock (net of any discounts, fees,
commissions and other expenses), divided by the Deemed Number, and (C) no further adjustment
shall be made to the Conversion Price upon the actual issuance of Common Stock upon
conversion, exercise or exchange of such Common Stock Equivalents.

          (ii) If, at any time while this Note is outstanding, the Company directly or indirectly
issues Common Stock Equivalents with an Effective Price or a number of underlying shares
that floats or resets or otherwise varies or is subject to adjustment based (directly or
indirectly) on market prices of the Common Stock (a “Floating Price Security”), then for
purposes of applying the preceding paragraph in connection with any subsequent conversion,
the Effective Price will be determined separately on each Conversion Date and will be deemed
to equal the lowest Effective Price at which any holder of such Floating Price Security is
entitled to acquire Common Stock on such Conversion Date (regardless of whether any such
holder actually acquires any shares on such date).

          (iii) The Company shall not issue any Common Stock Equivalents at an Effective Price
less than the Conversion Price (as adjusted hereunder to such date) unless prior to such
issuance (A) the Holder has consented to such issuance in writing and (B) the Company shall
have obtained all necessary shareholder and other approvals, including under the rules or
regulations of The NASDAQ Stock Market required for the Conversion Price under this Note to
be reduced to such Effective Price.

          (iv) Notwithstanding the foregoing, no adjustment will be made under this paragraph (d)
in respect of any issuances of Common Stock and Common Stock Equivalents made pursuant to
the definition of Excluded Stock.

     (e) Calculations. All calculations under this Section 11 shall be made to the
nearest cent or the nearest 1/100th of a share, as applicable. The number of shares of Common
Stock outstanding at any given time shall not include shares owned or held by or for the account of
the Company, and the disposition of any such shares shall be considered an issue or sale of Common
Stock.

     (f) Notice of Adjustments. Upon the occurrence of each adjustment pursuant to this
Section 11, the Company at its expense will promptly compute such adjustment in accordance
with the terms hereof and prepare and deliver to the Holder a certificate describing in reasonable
detail such adjustment and the transactions giving rise thereto, including all facts upon
which such adjustment is based.

19

 

     (g) Notice of Corporate Events. If the Company (i) declares a dividend or any other
distribution of cash, securities or other property in respect of its Common Stock, including
without limitation any granting of rights or warrants to subscribe for or purchase any capital
stock of the Company or any Subsidiary (other than Incentives or pursuant to Incentives), (ii)
authorizes or approves, enters into any agreement contemplating or solicits stockholder approval
for a Fundamental Change or (iii) authorizes the voluntary dissolution, liquidation or winding up
of the affairs of the Company, then the Company shall deliver to the Holder a notice describing the
material terms and conditions of such transaction, at least 20 Trading Days prior to the applicable
record or effective date on which a Person would need to hold Common Stock in order to participate
in or vote with respect to such transaction, and the Company will take all steps reasonably
necessary in order to insure that the Holder is given the practical opportunity to convert this
Note prior to such time so as to participate in or vote with respect to such transaction.

     12. No Fractional Shares. The Company shall not issue or cause to be issued
fractional Underlying Shares on conversion of this Note. If any fraction of an Underlying Share
would, except for the provisions of this Section 12, be issuable upon conversion of this
Note, the number of Underlying Shares to be issued will be rounded up to the nearest whole share.

     13. Notices. Any and all notices or other communications or deliveries hereunder
(including any Conversion Notice) shall be in writing and shall be deemed given and effective on
the earliest of (i) the date of transmission, if such notice or communication is delivered via
facsimile at the facsimile number specified in this Section 13 prior to 6:30 p.m. (New York
City time) on a Trading Day, (ii) the next Trading Day after the date of transmission, if such
notice or communication is delivered via facsimile at the facsimile number specified in this
Section 13 on a day that is not a Trading Day or later than 6:30 p.m. (New York City time)
on any Trading Day, (iii) the Trading Day following the date of mailing, if sent by nationally
recognized overnight courier service specifying next Business Day delivery, or (iv) upon actual
receipt by the party to whom such notice is required to be given, if by hand delivery. The address
and facsimile number of a party for such notices or communications shall be as set forth in the
Purchase Agreement, unless changed by such party by two Trading Days’ prior notice to the other
party in accordance with this Section 13.

     14. Miscellaneous.

     (a) This Note shall be binding on and inure to the benefit of the parties hereto and their
respective successors and permitted assigns. Subject to the restrictions on transfer set forth
herein, this Note may be assigned by the Holder. The Company shall not be permitted to assign this
Note absent the prior written consent of the Holder.

     (b) Subject to Section 13(a), nothing in this Note shall be construed to give to any
person or corporation other than the Company and the Holder any legal or equitable right, remedy or
cause under this Note.

20

 

     (c)  Governing Law; Venue; Waiver Of Jury Trial. all questions
concerning the construction, validity, enforcement and interpretation of this Note shall be
governed by and construed and enforced in accordance with the internal laws of the state of new
york (except for matters governed by corporate law in the state of maryland), without regard to the
principles of conflicts of law thereof. each party hereby irrevocably submits to the exclusive
jurisdiction of the state and federal courts sitting in the city of new york, borough of manhattan,

AMENDED AND RESTATED

WARRANT

			
	Warrant No. A-1
	 	Dated: June 8, 2007, as amended and
	 
	 	restated as of July 12, 2007

     ACE*COMM CORPORATION, a Maryland corporation (the “Company”), hereby certifies that, for value
received, Hale Fund Management, LLC or its registered assigns (the “Holder”), is entitled to
purchase from the Company up to a total of 155,063 shares of common stock, $0.01 par value per
share (the “Common Stock”), of the Company (each such share, a “Warrant Share” and all such shares,
the “Warrant Shares”) at an exercise price equal to $0.84 per share (as adjusted from time to time
as provided in Section 9, the “Exercise Price”), at any time and from time to time from and
after the date hereof and through and including June 8, 2014 (the “Expiration Date”), and subject
to the following terms and conditions. This Warrant (this “Warrant”) is one of a series of similar
warrants issued pursuant to that certain Securities Purchase Agreement, dated as of June 4, 2007 by
and among the Company and the Purchasers identified therein (the “Purchase Agreement”). All such
warrants are referred to herein, collectively, as the “Warrants.”

     This Warrant amends and restates in its entirety that certain Warrant numbered A-1 issued by
the Company, without constituting a novation thereof.

     1. Definitions. In addition to the terms defined elsewhere in this Warrant,
capitalized terms that are not otherwise defined herein have the meanings given to such terms in
the Purchase Agreement.

     2. Registration of Warrant. The Company shall register this Warrant, upon records to
be maintained by the Company for that purpose (the “Warrant Register”), in the name of the record
Holder hereof from time to time. The Company may deem and treat the registered Holder
of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any
distribution to the Holder, and for all other purposes, absent actual notice to the contrary.

 

 

     3. Registration of Transfers. This Warrant and all rights hereunder are transferable
in whole or in part upon the books of the Company by the Holder hereof; provided, however, that the
transferee shall agree in writing to be bound by the terms and subject to the conditions of this
Warrant and the Purchase Agreement. The Company shall register the transfer of any portion of this
Warrant in the Warrant Register, upon surrender of this Warrant, with the Form of Assignment
attached hereto duly completed and signed, to the Transfer Agent or to the Company at its address
specified herein. Upon any such registration or transfer, a new warrant to purchase Common Stock,
in substantially the form of this Warrant (any such new warrant, a “New Warrant”), evidencing the
portion of this Warrant so transferred shall be issued to the transferee and a New Warrant
evidencing the remaining portion of this Warrant not so transferred, if any, shall be issued to the
transferring Holder. The acceptance of the New Warrant by the transferee thereof shall be deemed
the acceptance by such transferee of all of the rights and obligations of a holder of a Warrant.

     4. Exercise and Duration of Warrants.

          (a) Subject to the limitations set forth in Section 12 hereof, this Warrant shall be
exercisable by the registered Holder at any time and from time to time on or after the date hereof
to and including the Expiration Date. At 6:30 P.M., New York City time on the Expiration Date, the
portion of this Warrant not exercised prior thereto shall be and become void and of no value;
provided that, if the average of the Closing Prices for the five Trading Days immediately prior to
(but not including) the Expiration Date exceeds the Exercise Price on the Expiration Date, then
this Warrant shall be deemed to have been exercised in full (to the extent not previously
exercised, and subject to the limitations set forth in Section 12 hereof) on a “cashless
exercise” basis at 6:30 P.M. New York City time on the Expiration Date. Notwithstanding anything
to the contrary herein, the Expiration Date shall be extended for each day following the Effective
Date that the Registration Statement is not effective.

          (b) A Holder may exercise this Warrant by delivering to the Company (i) an exercise notice, in
the form attached hereto (the “Exercise Notice”), appropriately completed and duly signed, and
(ii) payment of the Exercise Price for the number of Warrant Shares as to which this Warrant is
being exercised (which may take the form of a “cashless exercise” if so indicated in the Exercise
Notice and if a “cashless exercise” may occur at such time pursuant to Section 10 below),
and the date such items are delivered to the Company (as determined in accordance with the notice
provisions hereof) is an “Exercise Date.” The Holder shall not be required to deliver the original
Warrant in order to effect an exercise hereunder. Execution and delivery of the Exercise Notice
shall have the same effect as cancellation of the original Warrant and issuance of a New Warrant
evidencing the right to purchase the remaining number of Warrant Shares. The Holder shall deliver
the original Warrant to the Company within thirty (30) days after the full exercise of this
Warrant, provided, that the Holder’s failure to so deliver the original Warrant shall not
affect the validity of such exercise or any of the Company’s obligations under this Warrant and the
Company’s sole remedy for the Holder’s failure to deliver the original Warrant shall be to obtain
an affidavit of lost warrant from the Holder.

2

 

     5. Delivery of Warrant Shares.

          (a) Subject to Section 5(c) below and the limitations set forth in Section 12,
upon exercise of this Warrant, the Company shall promptly (but in no event later than three Trading
Days after the Exercise Date) issue or cause to be issued and cause to be delivered to or upon the
written order of the Holder and in such name or names as the Holder may designate, a certificate
for the Warrant Shares issuable upon such exercise, free of restrictive legends unless a
registration statement covering the resale of the Warrant Shares and naming the Holder as a selling
stockholder thereunder is not then effective and the Warrant Shares are not freely transferable
without volume restrictions pursuant to Rule 144 under the Securities Act. The Holder, or any
Person so designated by the Holder to receive Warrant Shares, shall be deemed to have become holder
of record of such Warrant Shares as of the Exercise Date. The Company shall, upon request of the
Holder, use its best efforts to deliver Warrant Shares hereunder electronically through the
Depository Trust Corporation or another established clearing corporation performing similar
functions.

          (b) Subject to Section 5(c) below and the limitations set forth in Section 12
hereof, this Warrant is exercisable, either in its entirety or, from time to time, for a portion of
the number of Warrant Shares. Upon surrender of this Warrant following one or more partial
exercises, the Company shall issue or cause to be issued, at its expense, a New Warrant evidencing
the right to purchase the remaining number of Warrant Shares.

          (c) In addition to any other rights available to a Holder, if the Company fails to deliver or
cause to be delivered to the Holder a certificate representing Warrant Shares by the third Trading
Day after the date on which delivery of such certificate is required by this Warrant, and if after
such third Trading Day the Holder purchases (in an open market transaction or otherwise) shares of
Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant Shares that the
Holder anticipated receiving from the Company (a “Buy-In”), then the Company shall, within three
Trading Days after the Holder’s request and in the Holder’s discretion, either (i) pay cash to the
Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions, if
any) for the shares of Common Stock so purchased (the “Buy-In Price”), at which point the Company’s
obligation to deliver such certificate (and to issue such Common Stock) shall terminate, or (ii)
promptly honor its obligation to deliver to the Holder a certificate or certificates representing
such Common Stock and pay cash to the Holder in an amount equal to the excess (if any) of the
Buy-In Price over the product of (A) such number of shares of Common Stock, times (B) the Closing
Price on the date of the event giving rise to the Company’s obligation to deliver such certificate.

          (d) The Company’s obligations to issue and deliver Warrant Shares in accordance with the terms
and subject to the conditions hereof are absolute and unconditional, irrespective of any action or
inaction by the Holder to enforce the same, any waiver or consent with respect to any provision
hereof, the recovery of any judgment against any Person or any action to enforce the same, or any
setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the
Holder or any other Person of any obligation to the Company or any violation or alleged violation
of law by the Holder or any other Person, and irrespective of any other circumstance which might
otherwise limit such obligation of the Company to the Holder in connection with the issuance of
Warrant Shares (other than such
limitations contemplated by this Warrant). Nothing herein shall limit a Holder’s right to
pursue any other remedies available to it hereunder, at law or in equity including, without
limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s
failure to timely deliver certificates representing shares of Common Stock upon exercise of the
Warrant as required pursuant to the terms hereof.

3

 

          (e) Each certificate for Warrant Shares shall bear a restrictive legend to the extent and as
provided in the Purchase Agreement and any certificate issued at any time in exchange or
substitution for any certificate bearing such legend shall also bear such legend, unless, in the
opinion of counsel for the Holder thereof (which opinion shall be reasonably satisfactory to
counsel for the Company), the securities represented thereby are not, at such time, required by law
to bear such legend.

     6. Charges, Taxes and Expenses. Issuance and delivery of certificates for shares of
Common Stock upon exercise of this Warrant shall be made without charge to the Holder for any issue
or transfer tax, withholding tax, transfer agent fee or other incidental tax or expense in respect
of the issuance of such certificates, all of which taxes and expenses shall be paid by the Company;
provided, however, that the Company shall not be required to pay any tax which may be payable in
respect of any transfer involved in the registration of any certificates for Warrant Shares or
Warrants in a name other than that of the Holder or an Affiliate thereof. The Holder shall be
responsible for all other tax liability that may arise as a result of holding or transferring this
Warrant or receiving Warrant Shares upon exercise hereof.

     7. Replacement of Warrant. If this Warrant is mutilated, lost, stolen or destroyed,
the Company shall issue or cause to be issued in exchange and substitution for and upon
cancellation hereof, or in lieu of and substitution for this Warrant, a New Warrant, but only upon
receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction and
customary and reasonable indemnity, if requested. Applicants for a New Warrant under such
circumstances shall also comply with such other reasonable regulations and procedures and pay such
other reasonable third-party costs as the Company may prescribe.

     8. Reservation of Warrant Shares. The Company covenants that it will at all times
reserve and keep available out of the aggregate of its authorized but unissued and otherwise
unreserved Common Stock, solely for the purpose of enabling it to issue Warrant Shares upon
exercise of this Warrant as herein provided, the number of Warrant Shares which are then issuable
and deliverable upon the exercise of this entire Warrant, free from preemptive rights or any other
contingent purchase rights of persons other than the Holder (taking into account the adjustments
and restrictions of Section 9). The Company covenants that all Warrant Shares so issuable
and deliverable shall, upon issuance and the payment of the applicable Exercise Price in accordance
with the terms hereof, be duly and validly authorized, issued and fully paid and nonassessable.
The Company will take all such action as may be necessary to assure that such shares of Common
Stock may be issued as provided herein without violation of any applicable law or regulation, or of
any requirements of any securities exchange or automated quotation system upon which the Common
Stock may be listed.

4

 

     9. Certain Adjustments. The Exercise Price and number of Warrant Shares issuable upon
exercise of this Warrant are subject to adjustment from time to time as set forth in this
Section 9.

          (a) Stock Dividends and Splits. If the Company, at any time while this Warrant is
outstanding, (i) pays a stock dividend on its Common Stock or otherwise makes a distribution on any
class of capital stock that is payable in shares of Common Stock, (ii) subdivides outstanding
shares of Common Stock into a larger number of shares, or (iii) combines outstanding shares of
Common Stock into a smaller number of shares, then in each such case the Exercise Price shall be
multiplied by a fraction of which the numerator shall be the number of shares of Common Stock
outstanding immediately before such event and of which the denominator shall be the number of
shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to
clause (i) of this paragraph shall become effective immediately after the record date for the
determination of stockholders entitled to receive such dividend or distribution, and any adjustment
pursuant to clause (ii) or (iii) of this paragraph shall become effective immediately after the
effective date of such subdivision or combination.

          (b) Pro Rata Distributions. If the Company, at any time while this Warrant is
outstanding, distributes to holders of Common Stock (i) evidences of its indebtedness, (ii) any
security (other than a distribution of Common Stock covered by the preceding paragraph),
(iii) rights or warrants to subscribe for or purchase any security, or (iv) cash or any other asset
(in each case, “Distributed Property”), then in each such case the Exercise Price in effect
immediately prior to the record date fixed for determination of stockholders entitled to receive
such distribution shall be adjusted (effective on such record date) to equal the product of such
Exercise Price times a fraction of which the denominator shall be the average of the Closing Prices
for the five Trading Days immediately prior to (but not including) such record date and of which
the numerator shall be such average less the then fair market value of the Distributed Property
distributed in respect of one outstanding share of Common Stock, as determined by the Company’s
independent certified public accountants that regularly examine the financial statements of the
Company (an “Appraiser”). In such event, the Holder, after receipt of the determination by the
Appraiser, shall have the right to select an additional appraiser (which shall be a nationally
recognized accounting firm), in which case such fair market value shall be deemed to equal the
average of the values determined by each of the Appraiser and such appraiser. As an alternative to
the foregoing adjustment to the Exercise Price, at the request of the Holder delivered before the
90th day after such record date, the Company will deliver to such Holder, within five Trading Days
after such request (or, if later, on the effective date of such distribution), the Distributed
Property that such Holder would have been entitled to receive in respect of the Warrant Shares for
which this Warrant could have been exercised immediately prior to such record date. If such
Distributed Property is not delivered to a Holder pursuant to the preceding sentence, then upon
expiration of or any exercise of the Warrant that occurs after such record date, such Holder shall
remain entitled to receive, in addition to the Warrant Shares otherwise issuable upon such exercise
(if applicable), such Distributed Property.

5

 

          (c) Fundamental Transactions. If, at any time while this Warrant is outstanding, (i)
the Company effects any merger or consolidation of the Company with or into another Person, (ii)
the Company effects any sale of all or substantially all of its assets in one or a series of
related transactions, (iii) any tender offer or exchange offer (whether by the Company
or another Person) is completed pursuant to which holders of Common Stock are permitted to
tender or exchange their shares for other securities, cash or property, (iv) the Company effects
any reclassification of the Common Stock or any compulsory share exchange pursuant to which the
Common Stock is effectively converted into or exchanged for other securities, cash or property
(other than as a result of a subdivision or combination of shares of Common Stock covered by
Section 9(a) above), or (v) there is a Change of Control (in any such case, a “Fundamental
Transaction”), then the Holder shall have the right thereafter to receive), upon exercise of this
Warrant, the same amount and kind of securities, cash or property as it would have been entitled to
receive upon the occurrence of such Fundamental Transaction if it had been, immediately prior to
such Fundamental Transaction, the holder of the number of Warrant Shares then issuable upon
exercise in full of this Warrant (the “Alternate Consideration”). The aggregate Exercise Price for
this Warrant will not be affected by any such Fundamental Transaction, but the Company shall
apportion such aggregate Exercise Price among the Alternate Consideration in a reasonable manner
reflecting the relative value of any different components of the Alternate Consideration. If
holders of Common Stock are given any choice as to the securities, cash or property to be received
in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate
Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction.
In the event of a Fundamental Transaction, the Company or the successor or purchasing Person, as
the case may be, shall execute with the Holder a written agreement providing that:

     (x) this Warrant shall thereafter entitle the Holder to purchase the Alternate
Consideration in accordance with this Section 9(c),

     (y) in the case of any such successor or purchasing Person, upon such consolidation,
merger, statutory exchange, combination, sale or conveyance such successor or purchasing
Person shall be jointly and severally liable with the Company for the performance of all of
the Company’s obligations under this Warrant and the Purchase Agreement, and

     (z) if registration or qualification is required under the Exchange Act or applicable
state law for the public resale by the Holder of shares of stock and other securities so
issuable upon exercise of this Warrant, such registration or qualification shall be
completed prior to such reclassification, change, consolidation, merger, statutory exchange,
combination or sale.

If, in the case of any Fundamental Transaction, the Alternate Consideration includes shares of
stock, other securities, other property or assets of a Person other than the Company or any such
successor or purchasing Person, as the case may be, in such Fundamental Transaction, then such
written agreement shall also be executed by such other Person and shall contain such additional
provisions to protect the interests of the Holder as the Board of Directors of the Company shall
reasonably consider necessary by reason of the foregoing. At the Holder’s request, any successor
to the Company or surviving entity in such Fundamental Transaction shall issue to the Holder a New
Warrant consistent with the foregoing provisions and evidencing the Holder’s right to purchase the
Alternate Consideration for the aggregate Exercise Price upon exercise thereof.

6

 

The terms of any
agreement pursuant to which a Fundamental Transaction is effected
shall include terms requiring any such successor or surviving entity to comply with the provisions
of this paragraph (c) and insuring that the Warrant (or any such replacement security) will be
similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction. Without
limiting the foregoing, in the event of a Fundamental Transaction, at the request of the Holder
delivered before the 90th day after such Fundamental Transaction, the Company (or any such
successor or surviving entity) will purchase the Warrant from the Holder for a purchase price,
payable in cash within five Trading Days after such request (or, if later, on the effective date of
the Fundamental Transaction), equal to the Black-Scholes value of the remaining unexercised portion
of this Warrant on the date of such request.

          (d) Subsequent Equity Sales.

          (i) If, at any time while this Warrant is outstanding, the Company or any Subsidiary
issues additional shares of Common Stock or rights, warrants, options or other securities or
debt convertible, exercisable or exchangeable for shares of Common Stock or otherwise
entitling any Person to acquire shares of Common Stock (collectively, “Common Stock
Equivalents”) at an effective net price to the Company per share of Common Stock (the
“Effective Price”) less than the Exercise Price (as adjusted hereunder to such date), then
the Exercise Price shall be reduced to equal the Effective Price. For purposes of this
paragraph, in connection with any issuance of any Common Stock Equivalents, (A) the maximum
number of shares of Common Stock potentially issuable at any time upon conversion, exercise
or exchange of such Common Stock Equivalents (the “Deemed Number”) shall be deemed to be
outstanding upon issuance of such Common Stock Equivalents, (B) the Effective Price
applicable to such Common Stock shall equal the minimum dollar value of consideration
payable to the Company to purchase such Common Stock Equivalents and to convert, exercise or
exchange them into Common Stock (net of any discounts, fees, commissions and other
expenses), divided by the Deemed Number, and (C) no further adjustment shall be made to the
Exercise Price upon the actual issuance of Common Stock upon conversion, exercise or
exchange of such Common Stock Equivalents.

          (ii) If, at any time while this Warrant is outstanding, the Company directly or
indirectly issues Common Stock Equivalents with an Effective Price or a number of underlying
shares that floats or resets or otherwise varies or is subject to adjustment based (directly
or indirectly) on market prices of the Common Stock (a “Floating Price Security”), then for
purposes of applying the preceding paragraph in connection with any subsequent exercise, the
Effective Price will be determined separately on each Exercise Date and will be deemed to
equal the lowest Effective Price at which any holder of such Floating Price Security is
entitled to acquire Common Stock on such Exercise Date (regardless of whether any such
holder actually acquires any shares on such date).

          (iii) The Company shall not issue any Common Stock Equivalents at an Effective Price
less than the Exercise Price (as adjusted hereunder to such date) unless prior to such
issuance (A) the Holder has consented to such issuance in writing and (B) the Company shall
have obtained all necessary shareholder and other approvals
required for the Conversion Price under this Warrant to be reduced to such Effective
Price.

7

 

          (iv) Notwithstanding the foregoing, no adjustment will be made under this paragraph (d)
in respect of any issuances of Common Stock or Common Stock Equivalents made pursuant to the
definition of Excluded Stock except for clause (D) thereof.

          (e) Number of Warrant Shares. Simultaneously with any adjustment to the Exercise
Price pursuant to paragraphs (a), (b) or (d) of this Section, the number of Warrant Shares that may
be purchased upon exercise of this Warrant shall be increased or decreased proportionately, so that
after such adjustment the aggregate Exercise Price payable hereunder for the increased or decreased
number of Warrant Shares shall be the same as the aggregate Exercise Price in effect immediately
prior to such adjustment.

          (f) Calculations. All calculations under this Section 9 shall be made to the
nearest cent or the nearest 1/100th of a share, as applicable. The number of shares of Common
Stock outstanding at any given time shall not include shares owned or held by or for the account of
the Company, and the disposition of any such shares shall be considered an issue or sale of Common
Stock.

          (g) Notice of Adjustments. Upon the occurrence of each adjustment pursuant to this
Section 9, the Company at its expense will promptly compute such adjustment in accordance
with the terms of this Warrant and prepare a certificate setting forth such adjustment, including a
statement of the adjusted Exercise Price and adjusted number or type of Warrant Shares or other
securities issuable upon exercise of this Warrant (as applicable), describing the transactions
giving rise to such adjustments and showing in detail the facts upon which such adjustment is
based. Upon written request, the Company will promptly deliver a copy of each such certificate to
the Holder and to the Company’s Transfer Agent.

          (h) Notice of Corporate Events. If the Company (i) declares a dividend or any other
distribution of cash, securities or other property in respect of its Common Stock, including
without limitation any granting of rights or warrants to subscribe for or purchase any capital
stock of the Company or any Subsidiary, (ii) authorizes or approves, enters into any agreement
contemplating or solicits stockholder approval for a Fundamental Transaction or (iii) authorizes
the voluntary dissolution, liquidation or winding up of the affairs of the Company, then the
Company shall deliver to the Holder a notice describing the material terms and conditions of such
transaction, at least 20 calendar days prior to the applicable record or effective date on which a
Person would need to hold Common Stock in order to participate in or vote with respect to such
transaction, and the Company will take all steps reasonably necessary in order to insure that the
Holder is given the practical opportunity to exercise this Warrant prior to such time so as to
participate in or vote with respect to such transaction; provided, however, that the failure to
deliver such notice or any defect therein shall not affect the validity of the corporate action
required to be described in such notice.

8

 

     10. Payment of Exercise Price. The Holder, at its election, may either pay the
Exercise Price in immediately available funds, or satisfy its obligation to pay the Exercise Price
through a “cashless exercise,” in which event the Company shall issue to the Holder the number
of Warrant Shares determined as follows:

	 	 	 	 	 
	 

	 	 	 	X = Y [(A-B)/A]
	 

	 	where:	 	 
	 

	 	 	 	X = the number of Warrant Shares to be
issued to the Holder.
	 
	 	 	 	 
	 

	 	 	 	Y = the number of Warrant Shares with
respect to which this Warrant is being
exercised.
	 
	 	 	 	 
	 

	 	 	 	A = the Current Market Price (as of the
date of such calculation) of one share of
Common Stock .
	 
	 	 	 	 
	 

	 	 	 	B = the Exercise Price (as adjusted to the
date of such calculation).

          For purposes of this Warrant, the “Current Market Price” of one share of the Company’s Common
Stock as of a particular date shall be determined as follows: (a) if traded on a national
securities exchange or through the Nasdaq Stock Market, the Current Market Price shall be deemed to
be the arithmetic average of the VWAPs for the five consecutive Trading Days immediately preceding
the applicable date; (b) if traded over-the-counter but not on the Nasdaq Stock Market, the Current
Market Price shall be deemed to be the average of the closing bid and asked prices as of five
business days immediately prior to the date of exercise indicated in the Notice of Exercise; and
(c) if there is no active public market, the Current Market Price shall be the fair market value of
the Common Stock as of the date of exercise, as determined by an independent appraiser selected in
good faith by the Holder.

          For purposes of Rule 144 promulgated under the Securities Act, it is intended, understood and
acknowledged that the Warrant Shares issued in a cashless exercise transaction shall be deemed to
have been acquired by the Holder, and the holding period for the Warrant Shares shall be deemed to
have commenced, on the date this Warrant was originally issued pursuant to the Purchase Agreement.

     11. Subject to the provisions of this Section 11, if following the two-year
anniversary of the date hereof, the Closing Prices for any 30 consecutive Trading Days are 200%
greater than the Exercise Price (the “Threshold Price”), then the Company will have the right, but
not the obligation (the “Call Right”), on 45 Trading Days prior written notice to the Holder, to
redeem any unexercised portion of this Warrant specified in that notice (the “Call Amount”). For
purposes of example only, if the Exercise Price is $1.00, then the Threshold Price would be $3.00
for the condition set forth in the preceding sentence to be satisfied.

9

 

          (a) To exercise the Call Right, the Company shall deliver to the Holder (a) an irrevocable
written notice (a “Call Notice”), indicating the Call Amount and (b) an Exchange Warrant (as
defined below). The date that the Company delivers the Call Notice to the Holders will be referred
to as the “Call Date.” Within 45 Trading Days of receipt of the Call Notice, the Holder shall
exercise this Warrant for up to the Call Amount in accordance with Section 4(b) above (provided,
that the Holder shall not have the right to elect “cashless exercise” pursuant to
Section 10 in connection with such exercise). Any portion of the Call Amount that is not
exercised by 6:30 p.m. (New York City time) on the 45th Trading Day following the date of receipt
of the Call Notice (the “Redemption Date”) shall be cancelled; provided, that if the average of the
Closing Prices for the five Trading Days immediately prior to (but not including) the Expiration
Date exceeds the Exercise Price on the Expiration Date, then this Warrant shall be deemed to have
been exercised in full (to the extent not previously exercised) on a “cashless exercise” basis at
6:30 P.M. New York City time on the Expiration Date if a “cashless exercise” may occur at such time
pursuant to Section 10 above. Any unexercised portion of this Warrant to which the Call Notice
does not pertain (the “Remaining Portion”) will be unaffected by such Call Notice. The Company
covenants and agrees that it will honor any Exercise Notice with respect to the Call Amount that is
tendered from the Call Date through and including 6:30 p.m. (New York City time) on the Redemption
Date.

          (b) Notwithstanding anything to the contrary set forth in this Warrant, the Company may not
require the cancellation of any unexercised Call Amount (and any Call Notice will be void), unless
from the beginning of the 30 consecutive Trading Days used to determine whether the Common Stock
has achieved the Threshold Price through the Redemption Date (the “Call Period”) (i) the Closing
Prices for each Trading Day during such Call Period exceeds the Threshold Price, (ii) the Company
shall have honored in accordance with the terms of this Warrant any Exercise Notice delivered by
6:30 p.m. (New York City time) on the Redemption Date, and (iii) the Registration Statement shall
be effective as to all Warrant Shares and the Prospectus thereunder available for use by the Holder
for the resale all such Warrant Shares.

          (c) Concurrently with the delivery of a Call Notice, the Company shall issue and deliver to
the Holder an Exchange Warrant (the “Exchange Warrant”), containing the same terms and conditions
as this Warrant, except that (i) the Exchange Warrant will entitle the Holder to purchase up to
such number of shares of Common Stock equal to the amount of Warrant Shares indicated in the Call
Notice as being subject to such Call Notice, and (ii) the “Exercise Price” for the Exchange Warrant
will equal [ ]% of the Closing Price on the Trading Day immediately preceding the Call Date. Any
Call Notice that is delivered without an Exchange Warrant meeting the requirements of this
Section 11(c) will be void and of no effect.

          (d) Notwithstanding anything to the contrary herein, if following the two-year anniversary of
the Effective Date the average of the Closing Prices for any 30 consecutive Trading Days are 200%
greater than the Exercise Price, then the Holder shall have the right to send the Company a written
notice (the “Holder Notice”) requiring the Company to exercise its Call Right with respect to all
or any portion of this Warrant. Upon receipt of the Holder Notice, the Company shall issue the
Call Notice to the Holder in accordance with this Section 11.

     12. Limitation on Exercise.

          (i) Subject to Section 12(ii), the number of shares of Common Stock that may be
acquired by a Holder upon any exercise of Warrants (or otherwise in respect hereof) shall be
limited to the extent necessary to insure that, following such exercise (or other issuance),
the total number of shares of Common Stock then beneficially owned by such Holder and its
Affiliates and any other Persons whose beneficial ownership of Common Stock would be
aggregated with such Holder’s for purposes of Section 13(d) of
the Exchange Act, does not exceed 4.999% of the total number of issued and outstanding
shares of Common Stock (including for such purpose the shares of Common Stock issuable upon
such conversion) (the “Threshold Percentage”). For such purposes, beneficial ownership
shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and
regulations promulgated thereunder.

10

 

          (ii) Notwithstanding the provisions of Section 12(i), the Holder shall have the right
at any time and from time to time, to waive the provisions of this Section insofar as they
relate to the Threshold Percentage or to increase its Threshold Percentage (but not in
excess of 9.999% (or such lower percentage if Section 16 of the Exchange Act or the rules
promulgated thereunder (or any successor statute or rules) is changed to reduce the
beneficial ownership percentage threshold thereunder to a percentage less than 9.999%)) by
written instrument delivered to the Company, but (i) any such waiver or increase will not be
effective until the 61st day after such notice is delivered to the Company, and (ii) any
such waiver or increase or decrease will apply only to the Holder and not to any other
holder of Warrants.

          (iii) Notwithstanding anything to the contrary contained herein, the maximum number of
shares of Common Stock that the Company may issue pursuant to the Transaction Documents at
an effective purchase price less than the Closing Price on the Trading Day immediately
preceding the Closing Date equals 19.99% of the outstanding shares of Common Stock
immediately preceding the Closing Date (the “Issuable Maximum”), unless the Company obtains
stockholder approval. If, at the time any Holder requests an exercise of any of the
Warrants and/or a conversion of any of the Series A Notes (or the Company is required or
permitted to pay in shares of Common Stock any principal or interest due under the Series A
Notes), the Actual Minimum would cause the Issuable Maximum to be exceeded (and if the
Company has not previously obtained the required stockholder approval), then the Company
shall issue to the Holder requesting such exercise and/or such conversion (and/or such
payment of principal or interest) a number of shares of Common Stock not exceeding such
Holder’s pro-rata portion of the Issuable Maximum (based on such Holder’s share (vis-à-vis
other Holders) of the aggregate purchase price paid under the Purchase Agreement and taking
into account any Warrant Shares previously issued to such Holder). For the purposes hereof,
“Actual Minimum” shall mean, as of any date, the maximum aggregate number of shares of
Common Stock then issued or potentially issuable in the future pursuant to the Transaction
Documents, including any Underlying Shares issuable upon exercise in full of all Warrants,
without giving effect to (x) any limits on the number of shares of Common Stock that may be
owned by a Holder at any one time, or (y) any additional Underlying Shares that could be
issuable as a result of any future possible adjustments made under Section 9(d).

     13. Fractional Shares. The Company shall not be required to issue or cause to be
issued fractional Warrant Shares on the exercise of this Warrant. If any fraction of a Warrant
Share would, except for the provisions of this Section, be issuable upon exercise of this Warrant,
the number of Warrant Shares to be issued will be rounded up to the nearest whole share or right to
purchase the nearest whole share, as the case may be.

11

 

     14. Notices. Any and all notices or other communications or deliveries hereunder
(including without limitation any Exercise Notice) shall be in writing and shall be deemed given
and effective on the earliest of (i) the date of transmission, if such notice or communication is
delivered via facsimile at the facsimile number specified in this Section prior to 6:30 p.m. (New
York City time) on a Trading Day, (ii) the next Trading Day after the date of transmission, if such
notice or communication is delivered via facsimile at the facsimile number specified in this
Section on a day that is not a Trading Day or later than 6:30 p.m. (New York City time) on any
Trading Day, (iii) the Trading Day following the date of mailing, if sent by a nationally
recognized overnight courier service specifying next Business Day delivery, or (iv) upon actual
receipt by the party to whom such notice is required to be given, if by hand delivery. The address
and facsimile number of a party for such notices or communications shall be as set forth in the
Purchase Agreement, unless changed by such party by two Trading Days’ prior notice to the other
party in accordance with this Section 14.

     15. Warrant Agent. The Company shall serve as warrant agent under this Warrant. Upon
30 days’ notice to the Holder, the Company may appoint a new warrant agent. Any corporation into
which the Company or any new warrant agent may be merged or any corporation resulting from any
consolidation to which the Company or any new warrant agent shall be a party or any corporation to
which the Company or any new warrant agent transfers substantially all of its corporate trust or
stockholders services business shall be a successor warrant agent under this Warrant without any
further act. Any such successor warrant agent shall promptly cause notice of its succession as
warrant agent to be mailed (by first class mail, postage prepaid) to the Holder at the Holder’s
last address as shown on the Warrant Register.

     16. Extension of Expiration Date. At the option of the Holder, the Expiration Date may
be extended for the number of Trading Days during any period occurring after the Required
Effectiveness Date in which (i) trading in the Common Stock is suspended by any Trading Market,
(ii) the Registration Statement is not effective, or (iii) the prospectus included in the
Registration Statement may not be used by the Holders for the resale of Registrable Securities
thereunder.

     17. Miscellaneous.

          (a) Subject to the restrictions on transfer set forth on the first page hereof and in
Section 3, this Warrant may be assigned by the Holder. This Warrant may not be assigned by
the Company except to a successor in the event of a Fundamental Transaction or with the prior
written consent of the Holder. This Warrant shall be binding on and inure to the benefit of the
parties hereto and their respective successors and assigns. Subject to the preceding sentence,
nothing in this Warrant shall be construed to give to any Person other than the Company and the
Holder any legal or equitable right, remedy or cause of action under this Warrant. This Warrant,
together with the other Transaction Documents, constitutes the entire agreement of the parties with
respect to the subject matter hereof. This Warrant may be amended only in writing signed by the
Company and the Holder and their successors and assigns. The restrictions set forth in Section
12 hereof may not be amended or waived.

12

 

          (b) The Company will not, by amendment of its governing documents or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities
or any other voluntary action, avoid or seek to avoid the observance or performance of any of the
terms of this Warrant, but will at all times in good faith assist in the carrying out of all such
terms and in the taking of all such action as may be necessary or appropriate in order to protect
the rights of the Holder against impairment. Without limiting the generality of the foregoing, the
Company (i) will not increase the par value of any Warrant Shares above the amount payable therefor
on such exercise, (ii) will take all such action as may be reasonably necessary or appropriate in
order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares on
the exercise of this Warrant, and (iii) will not close its stockholder books or records in any
manner which interferes with the timely exercise of this Warrant.

          (c) Governing Law; Venue; Waiver Of Jury Trial. all questions
concerning the construction, validity, enforcement and interpretation of this warrant shall be
governed by and construed and enforced in accordance with the laws of the state of new york (except
for matters governed by corporate law in the state of Maryland). each party hereby irrevocably
submits to the exclusive jurisdiction of the state and federal courts sitting in the city of new
york, borough of manhattan, for the adjudication of any dispute hereunder or in connection herewith
or with any transaction contemplated hereby or discussed herein (including with respect to the
enforcement of any of the transaction documents), and hereby irrevocably waives, and agrees not to
assert in any suit, action or proceeding, any claim that it is not personally subject to the
jurisdiction of any such court, that such suit, action or proceeding is improper. each party
hereby irrevocably waives personal service of process and consents to process being served in any
such suit, action or proceeding by mailing a copy thereof via registered or certified mail or
overnight delivery (with evidence of delivery) to such party at the address in effect for notices
to it under this agreement and agrees that such service shall constitute good and sufficient
service of process and notice thereof. nothing contained herein shall be deemed to limit in any way
any right to serve process in any manner permitted by law. the company hereby waives all rights to
a trial by jury.

          (d) The headings herein are for convenience only, do not constitute a part of this Warrant and
shall not be deemed to limit or affect any of the provisions hereof.

          (e) In case any one or more of the provisions of this Warrant shall be invalid or
unenforceable in any respect, the validity and enforceability of the remaining terms and provisions
of this Warrant shall not in any way be affected or impaired thereby and the parties will attempt
in good faith to agree upon a valid and enforceable provision which shall be a commercially
reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision
in this Warrant.

The undersigned is the Holder of Warrant No.                      (the “Warrant”) issued by ACE*COMM
