2

 

the “Exchange Act Filings”). All references herein to the Company’s “knowledge” shall refer to the
actual knowledge of any officer of the Company.

          4.1 Organization, Good Standing and Qualification. The Company is a corporation duly
organized, validly existing and in good standing under the laws of the Commonwealth of
Pennsylvania. The Company has the corporate power and authority to own and operate its properties
and assets, to execute and deliver this Agreement, and the Note and the Warrant to be issued in
connection with this Agreement, the Security Agreement relating to the Note dated as of the date
hereof between the Company and the Purchaser (the “Security Agreement”), the Registration Rights
Agreement relating to the Securities dated as of the date hereof between the Company and the

conversion of the Note (the “Note Shares”), to issue and sell the Warrant and the Warrant Shares,
and to carry out the provisions of this Agreement and the Related Agreements and to carry on its
business as presently conducted. The Company is duly qualified and is authorized to do business
and is in good standing as a foreign corporation in all jurisdictions in which the nature of its
activities and of its properties (both owned and leased) makes such qualification necessary, except
for those jurisdictions in which failure to do so would be reasonably expected not to have a
material adverse effect on the Company, its Subsidiaries or their assets, condition (financial or
otherwise), business or results of operations, taken as a whole (a “Material Adverse Effect”).

          4.2 Subsidiaries. The Company owns all of the issued and outstanding capital stock or other
equity interests of the business entities listed on Schedule 4.2 (the “Subsidiaries”). The Company
does not own or control any equity security or other interest of any other corporation, limited
partnership or other business entity.

          4.3 Capitalization; Voting Rights.

               (a) The authorized capital stock of the Company, as of the date hereof, consists of 38,000,000

10,832,152 shares of which are issued and outstanding, (ii) 5,000,000 are shares of Class B Common
Stock, no par value per share, none of which are issued and outstanding, and (iii) 3,000,000 are
shares of preferred stock, no par value per share, none of which are issued and outstanding.

               (b) Except as disclosed on Schedule 4.3 or the Exchange Act Filings, other than (i)
the shares reserved for issuance under the Company’s stock option plans; and (ii) shares which may
be granted pursuant to this Agreement and the Related Agreements, there are no outstanding options,
warrants, rights (including conversion or preemptive rights and rights of first refusal), proxy or
stockholder agreements, or arrangements or agreements of any kind for the purchase or acquisition
from the Company of any of its securities. Except as disclosed on Schedule 4.3 or the Exchange Act Filings, neither the offer, issuance or sale of any
of the Note or Warrant, or the issuance of any of the Note Shares or Warrant Shares, nor the
consummation of any transaction contemplated hereby will result in a change in the exercise or
conversion price or

3

 

number of any securities of the Company outstanding pursuant to anti-dilution
or other similar provisions binding upon the Company and contained in or affecting any such
securities.

               (c) All issued and outstanding shares of the Common Stock (i) have been duly authorized and
validly issued and are fully paid and nonassessable and (ii) were issued in compliance with all
applicable state and federal laws concerning the issuance of securities, except where the failure
to comply with state “blue sky” laws would not be reasonably expected to have a Material Adverse
Effect.

               (d) The rights, preferences, privileges and restrictions of the shares of the Common Stock are
as stated in the Company’s Articles of Incorporation (the “Charter”) and as provided under
applicable law. The Note Shares and Warrant Shares have been duly and validly reserved for
issuance. When issued in compliance with the provisions of this Agreement and the Company’s
Charter, the Securities will be validly issued, fully paid and nonassessable, and will be free of
any liens or encumbrances; provided, however, that the Securities may be subject to restrictions on
transfer under state and/or federal securities laws as set forth herein or as otherwise required by
such laws at the time a transfer is proposed.

          4.4 Authorization; Binding Obligations. All corporate action on the part of the Company, its
officers and directors necessary for the authorization of this Agreement and the Related
Agreements, the performance of all obligations of the Company hereunder at the Closing and, the
authorization, sale, issuance and delivery of the Note and Warrant has been taken or will be taken
prior to the Closing. The Agreement and the Related Agreements, when executed and delivered and to
the extent it is a party thereto, will be valid and binding obligations of the Company enforceable
in accordance with their terms, except (a) as limited by applicable bankruptcy, insolvency,
reorganization, moratorium or other laws of general application affecting enforcement of creditors’
rights, and (b) general principles of equity that restrict the availability of equitable or legal
remedies. The sale of the Note and the subsequent conversion of the Note into Note Shares are not
and will not be subject to any preemptive rights or rights of first refusal that have not been
properly waived or complied with. The issuance of the Warrant and the subsequent exercise of the
Warrant for Warrant Shares are not and will not be subject to any preemptive rights or rights of
first refusal that have not been properly waived or complied with.

          4.5 Liabilities. The Company, to its knowledge, has no material contingent liabilities,
except current liabilities incurred in the ordinary course of business and liabilities disclosed in
any Exchange Act Filings.

the Company arising from agreements entered into in the ordinary course of business), or (ii) the
transfer or license of any patent, copyright, trade secret or other proprietary right to or from
the

4

consistent with past practices); (iii) provisions restricting the development, manufacture or
distribution of the Company’s products or services, or (iv) indemnification by the Company with
respect to infringements of proprietary rights other than as incidental to licenses by the Company

               (b) Except as disclosed in the Exchange Act Filings, since December 31, 2002, the Company has
not (i) declared or paid any dividends, or authorized or made any distribution upon or with respect
to any class or series of its capital stock or otherwise, (ii) incurred any indebtedness for money
borrowed or any other liabilities (other than ordinary course obligations) individually in excess
of $150,000 or, in the case of indebtedness and/or liabilities individually less than $150,000, in
excess of $250,000 in the aggregate, (iii) made any loans or advances to any person not in excess,

such subsections.

          4.7 Obligations to Related Parties. Except as set forth on Schedule 4.7, there are no
obligations of the Company to officers, directors, or employees of the Company other than (a) for

expenses incurred on behalf of the Company, (c) for employee benefits made available to employees
or groups of employees (including stock option agreements outstanding under any stock option plan
approved by the Board of Directors of the Company) and (d) obligations listed in the Company’s
financial statements or disclosed in any of its Exchange Act Filings. Except as described above or
set forth on Schedule 4.7, none of the officers, directors or, to the Company’s knowledge,
key employees of the Company or any members of their immediate families, are indebted to the

opinions acceptable to the Purchaser from the Company’s legal counsel. The Company will provide,
at the Company’s expense, such other legal opinions in the future as are reasonably necessary for
the conversion of the Note and exercise of the Warrant.

     7. Covenants of the Purchaser.

          The Purchaser covenants and agrees with the Company as follows:

          7.1 Confidentiality. The Company agrees that it will not disclose, and will not include in any
public announcement, the name of the Purchaser, unless expressly agreed to by the Purchaser or
unless and until such disclosure is required by law or applicable regulation, and then only to the
extent of such requirement.

          7.2 Non-Public Information. The Purchaser agrees not to effect any sales in the shares of the
Company’s Common Stock while in possession of material, non-public information regarding the
Company if such sales would violate applicable securities law.

          7.3 No Shorting. Neither the Purchaser nor any of its affiliates or investment partners shall
or shall cause or advise any person or entity, directly or indirectly, to engage in “short sales”
of the Company’s Common Stock or any other hedging strategies involving the Company’s publicly
traded securities.

     7.4 Limitation on Acquisition of Common Stock of the Company. Notwithstanding anything
to the contrary contained in this Agreement, any Related Agreement, any document, instrument or
agreement entered into in connection with the transactions contemplated hereby or any document,
instrument or agreement entered into in connection with any other transaction entered into by and
between the Purchaser and the Company (and/or subsidiaries or affiliates of the Company), the
Purchaser shall not acquire stock in the Company (including, without limitation, pursuant to a
contract to purchase, by exercising an option or warrant, by converting any other security or
instrument, by acquiring or exercising any other right to acquire, shares of stock or other
security convertible into shares of stock in the Company, or otherwise, and such options, warrants,
conversion or other rights shall not be exercisable) to the extent such stock acquisition would
cause any interest (including any original issue discount) payable by the Company to the Purchaser
not to qualify as portfolio interest, within the meaning of Section 881(c)(2) of the Internal
Revenue Code of 1986, as amended (the “Code”) by reason of Section

16

 

881(c)(3) of the Code, taking into account the constructive ownership rules under Section 871(h)(3)(C) of the Code.

     8. Covenants of the Company and Purchaser Regarding Indemnification.

          8.1 Company Indemnification. The Company agrees to indemnify, hold harmless, reimburse and
defend Purchaser, each of Purchaser’s officers, directors, agents, affiliates, control persons, and
principal shareholders, against any claim, cost, expense, liability, obligation, loss or damage
(including reasonable legal fees) of any nature, incurred by or imposed upon the Purchaser which
results, arises out of or is based upon (i) any misrepresentations by Company or any breach of
representation or warranty by Company in this Agreement or in any exhibits or schedules attached
hereto or any Related Agreement, or (ii) any breach or default in performance by Company of any
covenant or undertaking to be performed by Company hereunder, or any other agreement entered into
by the Company and Purchaser relating hereto.

          8.2 Purchaser’s Indemnification. The Purchaser agrees to indemnify, hold harmless, reimburse
and defend the Company and each of the Company’s officers, directors, agents, affiliates, control
persons and principal shareholders, at all times against any claim, cost, expense, liability,
obligation, loss or damage (including reasonable legal fees) of any nature, incurred by or imposed
upon the Company which results, arises out of or is based upon (i) any misrepresentation by
Purchaser or any breach of any representation or warranty by Purchaser in this Agreement or in any
exhibits or schedules attached hereto or any Related Agreement; or (ii) any breach or default in
performance by Purchaser of any covenant or undertaking to be performed by Purchaser hereunder, or
any other agreement entered into by the Company and Purchaser relating hereto.

          8.3 Procedures. The procedures and limitations set forth in Section 9.5(c) and (d) shall
apply to the indemnifications set forth in Sections 8.1 and 8.2.

     9. Conversion of Convertible Note.

          9.1 Mechanics of Conversion.

               (a) Provided the Purchaser has notified the Company of the Purchaser’s intention to sell the
Note Shares and the Note Shares are included in an effective registration statement or are
otherwise exempt from registration when sold: (i) Upon the conversion of the Note or part thereof,
the Company shall, at its own cost and expense, take all necessary action (together with such other
documents as the transfer agent shall request) to assure that the Company’s transfer agent shall
issue shares of the Company’s Common Stock in the name of the Purchaser (or its nominee) or such
other persons as designated by the Purchaser in accordance with Section 9.1(b) hereof and in such
denominations to be specified representing the number of Note Shares issuable upon such conversion;
and (ii) The Company warrants that no instructions other than these instructions have been or will
be given to the transfer agent of the Company’s Common Stock and that after the Effective Date (as
hereinafter defined) the Note Shares issued will be freely transferable subject to the prospectus
delivery requirements of the Securities Act

17

 

and the provisions of this Agreement, and will not contain a legend restricting the resale or transferability of the Note Shares.

               (b) Purchaser will give notice of its decision to exercise its right to convert the Note or
part thereof by telecopying or otherwise delivering an executed and completed notice of the number
of shares to be converted to the Company (the “Notice of Conversion”). The Purchaser will not be
required to surrender the Note until the Purchaser receives a credit to the account of the
Purchaser’s prime broker through the DWAC system (as defined below), representing the Note Shares
or until the Note has been fully satisfied. Each date on which a Notice of Conversion is
telecopied or delivered to the Company in accordance with the provisions hereof shall be deemed a
“Conversion Date.” Pursuant to the terms of the Notice of Conversion, the Borrower will issue
instructions to the transfer agent accompanied by an opinion of counsel within one (1) business day
of the date of the delivery to Borrower of the Notice of Conversion and shall cause the transfer
agent to transmit the certificates representing the Conversion Shares to the Holder by crediting
the account of the Purchaser’s prime broker with the Depository Trust Company (“DTC”) through its
Deposit Withdrawal Agent Commission (“DWAC”) system within three (3) business days after receipt
by the Company of the Notice of Conversion (the “Delivery Date”).

               (c) The Company understands that a delay in the delivery of the Note Shares in the form
required pursuant to Section 9 hereof beyond the Delivery Date could result in economic loss to the
Purchaser. In the event that the Company fails to direct its transfer agent to deliver the Note
Shares to the Purchaser via the DWAC system within the time frame set forth in Section 9.1(b) above
and the Note Shares are not delivered to the Purchaser by the Delivery Date, as compensation to the
Purchaser for such loss, the Company agrees to pay late payments to the Purchaser for late issuance
of the Note Shares in the form required pursuant to Section 9 hereof upon conversion of the Note in the amount equal to the greater of (i) $500 per business
day after the Delivery Date or (ii) the Purchaser’s actual damages from such delayed delivery.
Notwithstanding the foregoing, the Company will not owe the Purchaser any late payments if the
delay in the delivery of the Note Shares beyond the Delivery Date is out of the control of the
Company and the Company is actively trying to cure the cause of the delay. The Company shall pay
any payments incurred under this Section in immediately available funds within three (3) trading
days of demand and, in the case of actual damages, the demand shall be accompanied by reasonable
documentation of the amount of such damages. Such documentation shall show the number of shares of
Common Stock the Purchaser is forced to purchase (in an open market transaction) which the
Purchaser anticipated receiving upon such conversion, and shall be calculated as the amount by
which (A) the Purchaser’s total purchase price (including customary brokerage commissions, if any)
for the shares of Common Stock so purchased exceeds (B) the aggregate principal and/or interest
amount of the Note, for which such Conversion Notice was not timely honored.

          Nothing contained herein or in any document referred to herein or delivered in connection
herewith shall be deemed to establish or require the payment of a rate of interest or other charges
in excess of the maximum permitted by applicable law. In the event that the rate of interest or
dividends required to be paid or other charges hereunder exceed the maximum amount permitted by
such law, any payments in excess of such maximum shall be credited against amounts owed by the
Company to a Purchaser and thus refunded to the Company.

18

 

          9.2 Maximum Conversion. The Purchaser shall not be entitled to convert on a Conversion Date,
nor shall the Company be permitted to require the Purchaser to accept, that amount of a Note in
connection with that number of shares of Common Stock which would be in excess of the sum of (i)
the number of shares of Common Stock actually owned by the Purchaser on a Conversion Date, and (ii)
the number of shares of Common Stock issuable upon the conversion of the Note and exercise of the
Warrant with respect to which the determination of this proviso is being made on a Conversion Date,
which would result in beneficial ownership by the Purchaser of more than 4.99% of the outstanding
shares of Common Stock of the Company on such Conversion Date. For the purposes of the immediately
preceding sentence, beneficial ownership shall be determined in accordance with Section 13(d) of
the Exchange Act and Regulation 13d-3 thereunder. The Purchaser may void the foregoing conversion
limitation upon 75 days prior notice to the Company or without any notice requirement upon the
occurrence of an Event of Default.

          9.3 Registration Rights.

          9.4 Registration Rights Granted. The Company hereby grants registration rights to the
Purchaser pursuant to a Registration Rights Agreement dated as of even date herewith between the
Company and the Purchaser.

          9.5 Indemnification.

               (a) In the event of a registration of any Registrable Securities under the Securities Act
pursuant to the Registration Rights Agreement, the Company will indemnify and hold harmless the
Purchaser, and its officers, directors and each other person, if any, who controls the Purchaser within the meaning of the Securities Act, against any losses, claims,
damages or liabilities, joint or several, to which the Purchaser, or such persons may become
subject under the Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or
alleged untrue statement of any material fact contained in any Registration Statement under which
such Registrable Securities were registered under the Securities Act pursuant to the Registration
Rights Agreement, any preliminary Prospectus or final Prospectus contained therein, or any
amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission
to state therein a material fact required to be stated therein or necessary to make the statements
therein not misleading, and will reimburse the Purchaser, and each such person for any reasonable
legal or other expenses incurred by them in connection with investigating or defending any such
loss, claim, damage, liability or action; provided, however, that the Company will
not be liable in any such case if and to the extent that any such loss, claim, damage or liability
(i) arises out of or is based upon an untrue statement or alleged untrue statement or omission or
alleged omission so made in conformity with information furnished by or on behalf of the Purchaser
or any such person in writing specifically for use in any such document or (ii) is pursuant to such
Purchaser’s use of an outdated or defective prospectus after the Company has provided written
notice to such Purchaser that the prospectus is outdated or defective.

               (b) In the event of a registration of the Registrable Securities under the Securities Act
pursuant to the Registration Rights Agreement, the Purchaser will indemnify and

19

 

hold harmless the Company, and its officers, directors and each other person, if any, who controls the Company within
the meaning of the Securities Act, against all losses, claims, damages or liabilities, joint or
several, to which the Company or such persons may become subject under the Securities Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon any untrue statement or alleged untrue statement of any material
fact which was furnished in writing by the Purchaser to the Company expressly for use in (and such
information is contained in) the Registration Statement under which such Registrable Securities
were registered under the Securities Act pursuant to the Registration Rights Agreement, any
preliminary Prospectus or final Prospectus contained therein, or any amendment or supplement
thereof, or arise out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements therein not
misleading, and will reimburse the Company and each such person for any reasonable legal or other
expenses incurred by them in connection with investigating or defending any such loss, claim,
damage, liability or action, provided, however, that the Purchaser will be liable
in any such case if and only to the extent that any such loss, claim, damage or liability arises
out of or is based upon an untrue statement or alleged untrue statement or omission or alleged
omission so made in conformity with information furnished in writing to the Company by or on behalf
of the Purchaser specifically for use in any such document. Notwithstanding the provisions of this
paragraph, the Purchaser shall not be required to indemnify any person or entity in excess of the
amount of the aggregate net proceeds received by the Purchaser in respect of Registrable Securities
in connection with any such registration under the Securities Act.

               (c) Promptly after receipt by a party entitled to claim indemnification hereunder (an
“Indemnified Party”) of notice of the commencement of any action, such Indemnified Party shall, if a claim for indemnification in respect thereof is to be made
against a party hereto obligated to indemnify such Indemnified Party (an “Indemnifying Party”),
notify the Indemnifying Party in writing thereof, but the omission so to notify the Indemnifying
Party shall not relieve it from any liability which it may have to such Indemnified Party other
than under this Section 9(c) and shall only relieve it from any liability which it may have to such
Indemnified Party under this Section 9(c) if and to the extent the Indemnifying Party is prejudiced
by such omission. In case any such action shall be brought against any Indemnified Party and it
shall notify the Indemnifying Party of the commencement thereof, the Indemnifying Party shall be
entitled to participate in and, to the extent it shall wish, to assume and undertake the defense,
and, after notice from the Indemnifying Party to such Indemnified Party of its election so to
assume and undertake the defense thereof, the Indemnifying Party shall not be liable to such
Indemnified Party under this Section 9(c) for any legal expenses subsequently incurred by such
Indemnified Party in connection with the defense thereof; if the Indemnified Party retains its own
counsel, then the Indemnified Party shall pay all fees, costs and expenses of such counsel,
provided, however, that, if the defendants in any such action include both the
Indemnified Party and the Indemnifying Party and the Indemnified Party shall have concluded upon
the written opinion of its counsel that there may be reasonable defenses available to it which are
different from or additional to those available to the Indemnifying Party or that the interests of
the Indemnified Party could reasonably be expected to conflict with the interests of the
Indemnifying Party, the Indemnified Party shall have the right to select one separate counsel and
to assume such legal defenses and otherwise to participate in the defense of such action, with

20

 

the reasonable expenses and fees of such separate counsel and other expenses related to such
participation to be reimbursed by the Indemnifying Party as incurred.

               (d) In order to provide for just and equitable contribution in the event of joint liability
under the Securities Act in any case in which either (i) the Purchaser, or any officer, director or
controlling person of the Purchaser, makes a claim for indemnification pursuant to this Section 9
but it is judicially determined (by the entry of a final judgment or decree by a court of competent
jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that
such indemnification may not be enforced in such case notwithstanding the fact that this Section 9
provides for indemnification in such case, or (ii) contribution under the Securities Act may be
required on the part of the Purchaser or such officer, director or controlling person of the
Purchaser in circumstances for which indemnification is provided under this Section 9; then, and in
each such case, the Company and the Purchaser will contribute to the aggregate losses, claims,
damages or liabilities to which they may be subject (after contribution from others) in such
proportion so that the Purchaser is responsible only for the portion represented by the percentage
that the public offering price of its securities covered by the Registration Statement bears to the
public offering price of all securities covered by such Registration Statement, provided,
however, that, in any such case, (A) the Purchaser will not be required to contribute any amount in
excess of the public offering price of all such securities offered by it pursuant to such
Registration Statement; and (B) no person or entity guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Act) will be entitled to contribution from any person or entity
who was not guilty of such fraudulent misrepresentation.

          9.6 Offering Restrictions. Except as previously disclosed in the SEC Reports or in the
Exchange Act Filings, or stock or stock options granted to employees or directors of the Company; or shares of preferred stock issued to pay
dividends in respect of the Company’s preferred stock; or equity or debt issued in connection with
an acquisition of a business or assets by the Company; or the issuance by the Company of stock in
connection with the establishment of a joint venture partnership or licensing arrangement (these
exceptions hereinafter referred to as the “Excepted Issuances”), the Company will not for so long
as the Note is outstanding issue any securities with a continuously variable/floating conversion
feature which are or could be (by conversion or registration) free-trading securities (i.e. common
stock subject to a registration statement) prior to the full repayment or conversion of the Note
(the “Exclusion Period”). Nothing contained in this Section 9.6 shall prohibit any fixed-price
offering of Company’s Common Stock (including the offering of securities convertible into Common
Stock at a fixed price); provided that (i) the fixed-price for such offering shall not be below the
then current market price of the Common Stock and (ii) the entire proceeds from such offering shall
be used to prepay all of the outstanding principal amount of the Note, plus any accrued and unpaid
interest thereon and any other applicable penalties or fees as set forth in the Note.

     10. Miscellaneous.

          10.1 Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAWS. ANY ACTION
BROUGHT BY EITHER PARTY AGAINST THE OTHER CONCERNING THE TRANSACTIONS CONTEMPLATED BY THIS
AGREEMENT SHALL BE BROUGHT

21

 

ONLY IN ANY STATE OR FEDERAL COURT SITTING IN THE BOROUGH OF MANHATTAN, CITY OF NEW YORK; PROVIDED THAT NOTHING CONTAINED IN THIS AGREEMENT SHALL BE DEEMED TO PRECLUDE
PURCHASER FROM BRINGING SUIT OR TAKING OTHER LEGAL ACTION IN ANY OTHER COURT OF COMPETENT
JURISDICTION AND NOTHING SHALL BE DEEMED TO PRECLUDE THE COMPANY FROM ASSERTING ANY DEFENSES OR
COUNTERCLAIMS IN ANY SUCH ACTIONS. BOTH PARTIES AND THE INDIVIDUALS EXECUTING THIS AGREEMENT AND
OTHER AGREEMENTS ON BEHALF OF SUCH PARTIES AGREE TO SUBMIT TO THE JURISDICTION OF SUCH COURTS AND
WAIVE TRIAL BY JURY. BOTH PARTIES AND THE INDIVIDUALS EXECUTING THIS AGREEMENT AND OTHER AGREEMENTS
ON BEHALF OF SUCH PARTIES FURTHER CONSENT THAT ANY SUMMONS, SUBPOENA OR OTHER PROCESS OR PAPERS
(INCLUDING, WITHOUT LIMITATION, ANY NOTICE OR MOTION OR OTHER APPLICATION TO EITHER OF THE
AFOREMENTIONED COURTS OR A JUDGE THEREOF) OR ANY NOTICE IN CONNECTION WITH ANY PROCEEDINGS
HEREUNDER OR THEREUNDER, MAY BE SERVED BY REGISTERED OR CERTIFIED MAIL, RETURN RECEIPT REQUESTED,
OR BY PERSONAL SERVICE PROVIDED A REASONABLE TIME FOR APPEARANCE IS PERMITTED, OR IN SUCH OTHER
MANNER AS MAY BE PERMISSIBLE UNDER THE RULES OF SAID COURTS. BOTH PARTIES AND THE INDIVIDUALS
EXECUTING THIS AGREEMENT AND OTHER AGREEMENTS ON BEHALF OF SUCH PARTIES WAIVE ANY OBJECTION TO
JURISDICTION AND VENUE OF ANY ACTION INSTITUTED HEREON OR THEREON IN THE SUPREME COURT FOR THE
STATE OF NEW YORK, COUNTY OF NEW YORK, OR THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN
DISTRICT OF NEW YORK AND SHALL NOT ASSERT ANY DEFENSE BASED ON LACK OF JURISDICTION OR VENUE OR BASED UPON
FORUM NON CONVENIENS FOR ANY ACTION FILED IN EITHER SUCH COURT. IN THE
EVENT THAT ANY PROVISION OF THIS AGREEMENT OR ANY OTHER AGREEMENT DELIVERED IN CONNECTION HEREWITH
IS INVALID OR UNENFORCEABLE UNDER ANY APPLICABLE STATUTE OR RULE OF LAW, THEN SUCH PROVISION SHALL
BE DEEMED INOPERATIVE TO THE EXTENT THAT IT MAY CONFLICT THEREWITH AND SHALL BE DEEMED MODIFIED TO
CONFORM WITH SUCH STATUTE OR RULE OF LAW. ANY SUCH PROVISION WHICH MAY PROVE INVALID OR
UNENFORCEABLE UNDER ANY LAW SHALL NOT AFFECT THE VALIDITY OR ENFORCEABILITY OF ANY OTHER PROVISION
OF ANY AGREEMENT.

          10.2 Survival. The representations, warranties, covenants and agreements made herein shall
survive any investigation made by the Purchaser and the closing of the transactions contemplated
hereby to the extent provided therein. All statements as to factual matters contained in any
certificate or other instrument delivered by or on behalf of the Company pursuant hereto in
connection with the transactions contemplated hereby shall be deemed to be representations and
warranties by the Company hereunder solely as of the date of this Agreement or such other
certificate or instrument.

          10.3 Successors and Assigns. Except as otherwise expressly provided herein, the provisions
hereof shall inure to the benefit of, and be binding upon, the successors, heirs, executors and
administrators of the parties hereto and shall inure to the benefit of and be enforceable by each
person who shall be a holder of the Securities from time to time, other than

22

 

the holders of Common Stock which has been sold by the Purchaser pursuant to Rule 144 or an effective registration
statement. Purchaser may assign the Note (or any portion thereof) or the Warrant, provided that
the assignees of the Note or the Warrant agree in writing to be bound by the terms of and perform
all of Purchaser’s obligations under this Agreement and the Related Agreements and such assignee
provides evidence reasonably satisfactory to the Company demonstrating compliance with applicable
securities laws, which shall include, without limitation, written certification from the assignee
of its sophistication and status as an accredited investor under Regulation D of the Securities Act
and a legal opinion from the transferor’s counsel that such transfer is exempt from the
registration requirements of applicable securities laws. Purchaser or any assignee may not assign
any of its rights or remedies under the Security Agreement or the Guaranty to any person or entity
other than a permitted assignee of the Note, and Purchaser may not assign any of its rights under
the Registration Rights Agreement to any person or entity other than a permitted assignee of the
Note or the Warrant. Purchaser or any assignee of the Note or Warrant may not assign its rights
hereunder or thereunder to a Competitor (as defined herein) of the Company. A “Competitor” shall
mean any business entity that (i) is primarily engaged in providing similar products or services as
the Company and from which such products and services the Company derived material revenues for the
prior twelve (12) months, and (ii) does business in any U.S. state in which the Company has an
established business. In the event there is more than one holder of the rights and obligations
under the Note, then an agent for such holders shall be appointed by the then holder(s) of the
majority principal amount outstanding under the Note for the sole purpose of dealing with the
Company in connection with administrative matters relating to this Agreement and the Related
Agreements, including in requesting waivers and consents. Unless such agent has authority from the holders to grant any such waiver, consent or to make any
amendments to this Agreement, the Note, the Guaranty or the Security Agreement without the consent
of the holders, all such grants of waivers, consents or amendments shall be made by such agent
acting upon the consent of the holders of a majority in principal amount then outstanding except
for (i) any modifications in the principal amount, rate of interest or fees payable under the Note
or any Related Agreement, (ii) postponements in any fixed payment date, (iii) releases or
discharges of the Company or any Subsidiary of any obligation or releases of any collateral except
as provided in this Agreement or the Related Agreements or (iv) any amendment to this Section 10.3,
which shall be approved by all holders affected thereby.

          10.4 Entire Agreement. This Agreement, the exhibits and schedules hereto, the Related
Agreements and the other documents delivered pursuant hereto constitute the full and entire
understanding and agreement between the parties with regard to the subjects hereof and no party
shall be liable or bound to any other in any manner by any representations, warranties, covenants
and agreements except as specifically set forth herein and therein.

          10.5 Severability. In case any provision of the Agreement shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby.

          10.6 Amendment and Waiver.

               (a) This Agreement may be amended or modified only upon the written consent of the Company and
the Purchaser.

23

 

               (b) The obligations of the Company and the rights of the Purchaser under this Agreement may be
waived only with the written consent of the Purchaser.

               (c) The obligations of the Purchaser and the rights of the Company under this Agreement may be
waived only with the written consent of the Company.

          10.7 Delays or Omissions. It is agreed that no delay or omission to exercise any right, power
or remedy accruing to any party, upon any breach, default or noncompliance by another party under
this Agreement or the Related Agreements, shall impair any such right, power or remedy, nor shall
it be construed to be a waiver of any such breach, default or noncompliance, or any acquiescence
therein, or of or in any similar breach, default or noncompliance thereafter occurring. All
remedies, either under this Agreement, the Note or the Related Agreements, by law or otherwise
afforded to any party, shall be cumulative and not alternative.

          10.8 Notices. All notices required or permitted hereunder shall be in writing and shall be
deemed effectively given: (a) upon personal delivery to the party to be notified, (b) when sent by
confirmed facsimile if sent during normal business hours of the recipient, if not, then on the next
business day, (c) three (3) business days after having been sent by registered or certified mail,
return receipt requested, postage prepaid, or (d) one day after deposit with a nationally
recognized overnight courier, specifying next day delivery, with written verification of receipt. All communications shall be sent to the
Company at the address as set forth on the signature page hereof with a copy in the case of the
Company to Legal Counsel, Numerex Corp., 1600 Parkwood Circle SE, Suite 200, Atlanta, Georgia
30339, facsimile number (770) 693-5951 and to Richard Baltz, Esq., Arnold & Porter LLP, 555
12th Street, N.W., Washington, D.C. 20004, facsimile number (202) 942-5999, to the
Purchaser at the address set forth on the signature page hereof for such Purchaser, with a copy in
the case of the Purchaser to Scott J. Giordano, Esq., Loeb & Loeb LLP, 405 Park Avenue, New York,
NY 10154, facsimile number (212) 407-4990, or at such other address as the Company or the Purchaser
may designate by written notice to the other parties hereto given in accordance herewith.

          10.9 Attorneys’ Fees. In the event that any suit or action is instituted to enforce any
provision in this Agreement, the prevailing party in such dispute shall be entitled to recover from
the losing party all fees, costs and expenses of enforcing any right of such prevailing party under
or with respect to this Agreement, including, without limitation, such reasonable fees and expenses
of attorneys and accountants, which shall include, without limitation, all fees, costs and expenses
of appeals. In the event of a settlement, each party shall bear its own fees, costs and expenses
unless otherwise directed by a court of competent jurisdiction.

          10.10 Titles and Subtitles. The titles of the sections and subsections of the Agreement are
for convenience of reference only and are not to be considered in construing this Agreement.

          10.11 Facsimile Signatures; Counterparts. This Agreement may be executed by facsimile
signatures and in any number of counterparts, each of which shall be an original, but all of which
together shall constitute one instrument. Any party delivering an executed

24

 

counterpart of this Agreement by facsimile transmission shall deliver an original of such counterpart to the other
party hereto within two (2) business days; provided, however, that the failure to so deliver any
original counterpart shall not affect the validity or enforceability of this Agreement as against
such party.

          10.12 Broker’s Fees. Except as set forth on Schedule 11.12 hereof, Each party hereto
represents and warrants that no agent, broker, investment banker, person or firm acting on behalf
of or under the authority of such party hereto is or will be entitled to any broker’s or finder’s
fee or any other commission directly or indirectly in connection with the transactions contemplated
herein. Each party hereto further agrees to indemnify each other party for any claims, losses or
expenses incurred by such other party as a result of the representation in this Section 11.12 being
untrue.

          10.13 Construction. Each party acknowledges that its legal counsel participated in the
preparation of this Agreement and the Related Agreements and, therefore, stipulates that the rule
of construction that ambiguities are to be resolved against the drafting party shall not be applied
in the interpretation of this Agreement to favor any party against the other.

25

CONVERTIBLE TERM NOTE

     FOR VALUE RECEIVED, NUMEREX CORP., a Pennsylvania corporation (the “Borrower”), hereby

FIVE HUNDRED THOUSAND DOLLARS ($1,500,000), or such lesser principal amount as may be from time to
time owing to the Holder hereunder, together with any accrued and unpaid interest hereon, on
January 28, 2008 (the “Maturity Date”) if not sooner paid.

     Capitalized terms used herein without definition shall have the meanings ascribed to such
terms in that certain Securities Purchase Agreement dated as of the date hereof between the
Borrower and the Holder (the “Purchase Agreement”).

     The following terms shall apply to this Note:

ARTICLE I

INTEREST & AMORTIZATION

     1.1. Interest Rate and Payment. Subject to Article IV and Section 5.1 hereof,
interest payable on this Note shall accrue at a rate per annum equal to eight percent (8%) (the
“Contract Rate”). Interest shall be payable monthly in arrears commencing on March 1, 2005, on the
first day of each consecutive calendar month thereafter (each, a “Repayment Date”), and on the
Maturity Date, whether by acceleration or otherwise.

     1.2. Monthly Principal Payments. Amortizing payments of the aggregate principal
amount outstanding under this Note at any time (the “Principal Amount”) shall begin on July 1,
2005 and shall recur on the first calendar day of each succeeding month thereafter (each, an
“Amortization Date”) until the Maturity Date. The Borrower shall make monthly payments to the
Holder as follows: beginning on the first Amortization Date and ending on the Amortization Date of
January 1, 2006, the Borrower shall pay to the Holder $26,000 per month on each Repayment Date;
beginning on the Amortization Date of February 1, 2006 and ending on the Amortization Date of July
1, 2006, the Borrower shall pay to the Holder $40,000 per month on each Repayment Date; and
beginning on the Amortization Date of August 1, 2006 and ending on the Maturity Date, the Borrower
shall pay to the Holder one eighteenth (1/18th) of the remaining principal balance due
under this Note in equal monthly installments on each Repayment Date;

 

each of the aforementioned monthly payments shall be made together with any accrued and unpaid
interest to date on such portion of the Principal Amount plus any and all other amounts which are
then owing under this Note but have not been paid (collectively, the “Monthly Amount”).

ARTICLE II

BORROWER PAYMENT OPTIONS

     2.1. (a) Payment of Monthly Amount in Cash or Common Stock. Subject to the terms
hereof, the Borrower shall have the sole option to determine whether to satisfy payment of the
Monthly Amount on each Repayment Date either in cash or in shares of its Class A common stock, no
par value per share (the “Common Stock”), or a combination of both. Each month, ten (10) days
prior to a Repayment Date, the Borrower shall deliver to the Holder a written irrevocable notice in
the form of Exhibit B attached hereto electing to pay the Monthly Amount payable on the
next Repayment Date in either cash or Common Stock, or a combination of both (each, a “Repayment
Election Notice”) (the date by which such notice is required to be given being hereinafter referred
to as the “Notice Date”). If a Repayment Election Notice is not delivered to the Holder by the
applicable Notice Date for such Repayment Date, then the Monthly Amount due on such Repayment Date
shall be paid in cash. Any portion of the Monthly Amount paid in cash on a Repayment Date, shall
be paid to the Holder an amount equal to 102% of the cash portion of the Monthly Amount then
payable in satisfaction of such obligation. If the Borrower repays all or a portion of the Monthly
Amount in shares of Common Stock, the number of such shares to be issued for such Repayment Date
shall be the number determined by dividing (x) the portion of the Monthly Amount to be paid in
shares of Common Stock, by (y) the Fixed Conversion Price. For purposes hereof, the “Fixed
Conversion Price” means $5.31; provided, however, that upon the occurrence of any stock split,
stock dividend, combination of shares or reverse stock split pertaining to the Common Stock, the
Fixed Conversion Price shall be proportionately increased or decreased as necessary to reflect the
proportionate change in the shares of Common Stock issued and outstanding as a result of such stock
split, stock dividend, combination of shares or reverse stock split.

     (b) Monthly Amount Common Stock Payment Guidelines. Subject to Sections 2.1 and 2.2
hereof, if the Borrower has elected to pay all or a portion of the Monthly Amount due on such
Repayment Date in shares of Common Stock and the closing price of the Common Stock as reported by
Bloomberg, L.P. on the Principal Market (as defined in Section 4.7 hereof) for the seven (7)
trading days preceding a Repayment Date was less than 110% of the Fixed Conversion Price, then the
Borrower shall pay the Monthly Amount in cash instead. Any part of the Monthly Amount due on such
Repayment Date that the Borrower did not elect to pay in shares of Common Stock shall be paid by
the Borrower in cash on such Repayment Date. Any part of the Monthly Amount due on such Repayment
Date which the Borrower elected to pay in shares of Common Stock but which must be paid in cash
(because the closing price of the Common Stock for the seven (7) trading days preceding the
applicable Repayment Date was less than 110% of the Fixed Conversion Price) shall be paid within
three (3) business days of the applicable Repayment Date.

     2.2. No Effective Registration. Notwithstanding anything to the contrary herein, the
Borrower shall not repay any part of its obligations to the Holder hereunder in shares of

2

 

Common Stock if (i) there fails to exist an effective current Registration Statement (as
defined in the Registration Rights Agreement) covering resale of the shares of Common Stock to be
issued in connection with such payment, or (ii) an Event of Default hereunder exists and is
continuing, unless such Event of Default is cured within any applicable cure period or is
otherwise waived in writing by the Holder in whole or in part at the Holder’s option.

     2.3. Optional Prepayments in Common Stock. Subject to Section 2.2 hereof, if the
average closing price of the Common Stock on the Principal Market is greater than 110% of the Fixed
Conversion Price for a period of at least five (5) consecutive trading days, then the Borrower may,
at its sole option, provide the Holder written notice (a “Prepayment Call Notice”) requiring the
conversion at the then applicable Fixed Conversion Price of all or a portion of the outstanding
principal, interest and fees outstanding under this Note (subject to compliance with this Section
2.3 and Section 3.2, together with accrued interest on the amount being prepaid, as of the date set
forth in such Prepayment Call Notice (the “Prepayment Call Date”). The Prepayment Call Date shall
be at least ten (10) trading days following the date of the Prepayment Call Notice. On the
Prepayment Call Date, the Borrower shall deliver to the Holder certificates evidencing the shares
of Common Stock issued in satisfaction of the principal and interest being prepaid.
Notwithstanding the foregoing, the Borrower’s right to issue shares of Common Stock in satisfaction
of its obligations under this Note shall be subject to the limitation that the market price of the
Common Stock issued in connection with any Prepayment Call Notice shall exceed the Fixed Conversion
Price as of the Prepayment Call Date and for the seven (7) trading days immediately preceding the
Prepayment Call Date. If the price of the Common Stock falls below 110% of the Fixed Conversion
Price as of, or during the seven (7) trading day period immediately preceding, the Prepayment Call
Date, then the Prepayment Call Notice shall be null and void and no conversion shall be required
hereunder.

     The Borrower shall not be permitted to give the Holder more than one Prepayment Call Notice
under this Note during any 22-day period.

     Any principal amount of this Note which is prepaid pursuant to this Section 2.3 shall be
deemed to constitute payments of outstanding principal applying to Monthly Amounts for the
remaining Repayment Dates in chronological order.

     2.4. Optional Redemption in Cash. (a) Subject to Section 2.4(b), the Borrower will
not have the option of redeeming or prepaying in cash any Principal Amount during the twelve (12)
months immediately following the date hereof. Thereafter, the Borrower will have the option of
redeeming or prepaying any Principal Amount (“Optional Redemption”) by paying to the Holder a sum
of money equal to: (i) 110% of the Principal Amount if such redemption or prepayment occurs after
twelve (12) months from the date hereof and prior to the end of the eighteenth (18th)
month from the date hereof; (ii) 105% of the Principal Amount if such redemption or prepayment
occurs during the period commencing on the first day following the eighteenth (18th)
month anniversary of the date hereof and prior to the end of the twenty-fourth (24th)
month from the date hereof; and (iii) 103% of the Principal Amount if such redemption or prepayment
occurs at any time thereafter but before the Maturity Date. Each such redemption or prepayment
made pursuant to this Section 2.4 shall include all accrued but unpaid interest on that portion of
the Principal Amount so prepaid or redeemed and any and all other sums due, accrued or payable to
the Holder arising under this Note or the Purchase Agreement or any Related

3

 

Document (as defined in the Purchase Agreement) (the “Redemption Amount”) outstanding on the
day written notice of redemption (the “Notice of Redemption”) is given to the Holder, which Notice
of Redemption shall specify the date for such Optional Redemption (the “Redemption Payment Date”).
A Notice of Redemption shall not be effective with respect to any portion of this Note for which
the Holder has a pending election to convert pursuant to Section 3.1 and the Redemption Amount
shall be determined as if such election to convert had been completed immediately prior to the date
of the Notice of Redemption. The Redemption Payment Date shall be not earlier than the day after
the date of the Notice of Redemption and not later than seven (7) days after the date of the Notice
of Redemption. On the Redemption Payment Date, the Redemption Amount must be paid in good funds to
the Holder. In the event the Borrower fails to pay the Redemption Amount by the Redemption Payment
Date, then such Redemption Notice will be null and void.

(b) Notwithstanding anything contained herein to the contrary, ifBorrower consummates any Permitted
Non-Core Asset Sale (as defined in the Convertible Term Note dated January 13, 2004 between
Borrower and Holder)then the Borrower shall prepay an amount equal to (i) fifty percent (50%) of
the net proceeds of each such Non-Core Asset Sale (i.e., gross proceeds less the reasonable costs
of such sales, which shall include, without limitation, reasonable fees, costs and expenses of
legal, financial, investment banking, accounting or other professional advisors, broker
commissions, closing costs, taxes, diligence fees and other costs of readying the Permitted
Non-Core Assets for sale) plus (ii) the Adjusted Premium, with such prepayments to be made
concurrently with the consummation of each Permitted Non-Core Asset Sale. For purposes hereof, the
term “Adjusted Premium” shall mean: (a) 10% of the reduction in the Principal Amount resulting from
the payment set forth in (i) above if such prepayment occurs prior to the end of the sixth
(6th) month from the date hereof; (b) 5% of the reduction in the Principal Amount if
such prepayment occurs during the period commencing on the first day following the sixth
(6th) month anniversary of the date hereof and prior to the end of the eighteenth
(18th) month from the date hereof; and (c) 3% of the reduction in the Principal Amount
if such prepayment occurs at any time thereafter but before the Maturity Date.

     2.5. Mandatory Redemption Upon Failure to Cause an Effective Registration Statement to be
Filed. If on or prior to January 28, 2006, the Borrower shall fail to file and cause to exist
a current effective Registration Statement (as defined in the Registration Rights Agreement)
covering resale of the shares of Common Stock underlying this Note and the Common Stock Purchase
Warrant, dated as of the date hereof, granted by the Borrower to the Holder, then Holder shall have
the right, upon six (6) month’s prior written notice to the Borrower, to demand repayment in full
of all amounts outstanding under this Note, including, but not limited to, any penalties set forth
in this Article IV and all accrued and unpaid interest and fees thereon.

ARTICLE III

CONVERSION RIGHTS

     3.1. Holder’s Conversion Rights. (a) The Holder shall have the right, but not the
obligation, to convert all or any portion of the then aggregate outstanding principal amount of
this Note, together with interest and fees due hereon, into shares of Common Stock subject to the
terms and conditions set forth in this Article III.

4

 

     (b) Notwithstanding anything contained herein to the contrary, during the six (6) month period
following an effective current Registration Statement (as defined in the Registration Rights
Agreement), so long as no Event of Default shall have occurred and be continuing, the Holder shall
limit the number of shares of Common Stock to which it voluntarily converts a portion of this Note,
on a monthly basis, to not greater than ten percent (10%) of the total number of shares of the
Borrower’s Common Stock that traded during the month immediately preceding such voluntary
conversion by the Holder. In addition, so long as no Event of Default shall have occurred and be
continuing, during the period commencing on the date hereof and ending on January 28, 2007, the
Holder shall not sell the Borrower’s Common Stock at a price per share less than the lower of (a)
$3.80 per share or (b) the volume weighted average closing price (the “VWAP”) of the Borrower’s
Common Stock for the three (3) trading days immediately preceding the date hereof (the “Floor
Price”), unless, in each case, the VWAP of the Borrower’s Common Stock remains below the Floor
Price for any ninety (90) day period.

     3.2. Conversion Limitation. Notwithstanding anything contained herein to the contrary,
pursuant to the terms of this Note, the Holder shall not be entitled to convert on a Conversion
Date (as defined in Section 3.3(b)) that number of shares of Common Stock which would be in excess
of the sum (i) the number of shares of Common Stock actually owned by the Holder and its affiliates
on a Conversion Date and (ii) the number of shares of Common Stock issuable upon the conversion of
this Note and exercise of the warrants held by such Holder and its affiliates with respect to which
the determination of this proviso is being made on a Conversion Date, which would result in
beneficial ownership by the Holder and its affiliates of more than 4.99% of the outstanding shares
of Common Stock of the Borrower on such date. For the purposes of the immediately preceding
sentence, beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange
Act and Regulation 13d-3 thereunder. The Holder may void the limitation described in this Section
3.2 upon 75 days prior notice to the Borrower or without any notice requirement upon an Event of
Default.

     3.3. Procedures for Conversion. (a) In the event that the Holder elects to convert
this Note into Common Stock, the Holder shall give written notice of such election by delivering to
the Borrower an executed and completed notice of conversion (the “Notice of Conversion”), such
Notice of Conversion shall provide a breakdown in reasonable detail of the Principal Amount,
accrued interest and fees being converted. On each Conversion Date (as hereinafter defined) and in
accordance with the Notice of Conversion, the Holder shall make the appropriate reduction to the
Principal Amount, accrued interest and fees as entered in its records and shall provide written
notice thereof to the Borrower within two (2) business days after the Conversion Date. Each date
on which a Notice of Conversion is delivered or telecopied to the Borrower in accordance with the
provisions hereof shall be deemed a Conversion Date (the “Conversion Date”). A form of Notice of
Conversion to be employed by the Holder is annexed hereto as Exhibit A.

     (b) Pursuant to the terms of the Notice of Conversion the Borrower will issue instructions to
the transfer agent (together with such other documents as the transfer agent may request), within
one (1) business day of the date of the delivery to Borrower of the Notice of Conversion. If the
Registration Statement (as defined in the Registration Rights Agreement) is effective or the
Conversion Shares are eligible for sale pursuant to Rule 144, Borrower shall cause the transfer
agent to transmit the certificates representing the Conversion Shares to the

5

 

Holder by crediting the account of the Holder’s designated broker with the Depository Trust
Corporation (“DTC”) through its Deposit Withdrawal Agent Commission (“DWAC”) system within three
(3) business days after receipt by the Borrower of the Notice of Conversion (the “Delivery Date”).
Upon delivery to Holder of such certificates through DWAC in accordance with this Section 3.3(b),
Holder covenants to Borrower to (i) sell, transfer or dispose of all Conversion Shares pursuant to
the Registration Statement in accordance with the plan of distribution described therein or the
provisions of Rule 144, as applicable, and (ii) fulfill applicable prospectus delivery requirements
imposed by applicable federal securities laws. In the case of the exercise of the conversion
rights set forth herein the conversion privilege shall be deemed to have been exercised and the
Conversion Shares issuable upon such conversion shall be deemed to have been issued upon the date
of receipt by the Borrower of the Notice of Conversion. The Holder shall be treated for all
purposes as the record holder of such Common Stock, unless the Holder provides the Borrower written
instructions to the contrary.

     3.4. Conversion Mechanics. (a) The number of shares of Common Stock to be issued upon
each conversion of this Note shall be determined by dividing that portion of the principal and
interest and fees to be converted, if any, by the Fixed Conversion Price. In the event of any
conversions of outstanding principal amount under this Note in part pursuant to this Article III,
such conversions shall be deemed to constitute conversions of outstanding principal amount applying
to Monthly Amounts for the remaining Repayment Dates in chronological order.

     (b) No fractional shares of Common Stock shall be issued upon any conversion of this Note. In
lieu of any fractional share to which Holder would otherwise be entitled, the Borrower shall pay
Holder cash equal to the product of such fraction multiplied by the fair market value as of the
date of Conversion of a share of Common Stock, as determined in good faith by the Borrower’s Board
of Directors (or an authorized subcommittee thereof).

ARTICLE IV

EVENTS OF DEFAULT

     If an Event of Default (as defined below) occurs and is continuing, the Borrower’s rights
under Sections 2.1, 2.3 and 2.4 shall immediately cease and be of no further effect until such time
as the Event of Default has been cured, or has been waived by the Holder. Upon the occurrence and
continuance of an Event of Default beyond any applicable grace period, the Holder, at its sole and
absolute discretion, may make all sums of principal, interest and other fees then remaining unpaid
hereon and all other amounts payable hereunder due and payable within five (5) days after written
notice from Holder to Borrower (each occurrence being a “Default Notice Period”), provided,
however, that such Default Notice Period shall not apply to Sections 4.3, 4.6 and 4.9
below. In the event of such an acceleration, the amount due and owing to the Holder shall be 115%
of the Principal Amount (plus accrued and unpaid interest and fees, if any). If, with respect to
any Event of Default other than a payment default described in Section 4.1 below, within the
Default Notice Period the Borrower cures the Event of Default, the Event of Default will be deemed
to no longer exist and any rights and remedies of Holder pertaining to such Event of Default will
be of no further force or effect.

     The occurrence of any of the following events is an “Event of Default”:

6

 

     4.1. Failure to Pay Principal, Interest or other Fees. The Borrower fails to pay when
due any installment of principal, interest or other fees hereon in accordance herewith, or the
Borrower fails to pay when due any amount due under any other promissory note issued by Borrower.

     4.2. Breach of Covenant. The Borrower breaches any material covenant or other term or
condition of this Note or the Purchase Agreement in any material respect and such breach, if
subject to cure, continues for a period of thirty (30) days after the occurrence thereof.

     4.3. Breach of Representations and Warranties. Any material representation or
warranty of the Borrower made herein, in the Purchase Agreement, or in any Related Document shall
have been materially false or misleading when made and shall not be cured for a period of ten (10)
days after written notice thereof is received by the Borrower from the Holder.

     4.4. Receiver or Trustee. The Borrower shall make an assignment for the benefit of
creditors, or apply for or consent to the appointment of a receiver or trustee for it or for a
substantial part of its property or business; or such a receiver or trustee shall otherwise be
appointed.

     4.5. Judgments. Any money judgment, writ or similar final process shall be entered or
filed against the Borrower or any of its property or other assets for more than $300,000, and shall
remain unvacated, unbonded or unstayed for a period of ninety (90) days.

     4.6. Bankruptcy. Bankruptcy, insolvency, reorganization or liquidation proceedings or
other proceedings or relief under any bankruptcy law or any law for the relief of debtors shall be
instituted by or against the Borrower and, in the case of an involuntary case or proceeding, such
case or proceeding is not dismissed within sixty (60) days following the commencement thereof.

     4.7. Stop Trade. An SEC stop trade order or Principal Market trading suspension of
the Common Stock shall be in effect for five (5) consecutive days or five (5) days during a period
of ten (10) consecutive days, excluding in all cases a suspension of all trading on a Principal
Market, provided that the Borrower shall not have been able to cure such trading suspension within
30 days of the notice thereof or list the Common Stock on another Principal Market within 60 days
of such notice. The “Principal Market” for the Common Stock shall include the NASD OTC Bulletin
Board, NASDAQ SmallCap Market, NASDAQ National Market System, American Stock Exchange, or New York
Stock Exchange, whichever of the foregoing is at the time the principal trading exchange or market
for the Common Stock, or any securities exchange or other securities market on which the Common
Stock is then being listed or traded.

     4.8. Default Under Security Agreement. An Event of Default shall have occurred under
and as defined in the Security Agreement, which shall not have been cured during any applicable
cure or grace period.

7

 

ARTICLE V

DEFAULT RELATED PROVISIONS

     5.1. Payment Grace Period. The Borrower shall have a three (3) business day grace
period to pay any monetary amounts due under this Note or the Purchase Agreement or any Related
Document, after which grace period a default interest rate of five percent (5%) per annum above the
then applicable interest rate hereunder shall apply to the monetary amounts due.

     5.2. Conversion Privileges. The conversion privileges set forth in Article III shall
remain in full force and effect immediately from the date hereof and until this Note is paid in
full or until all of the then outstanding Principal Amount and interest and other fees payable
hereunder shall have been converted into shares of Common Stock.

ARTICLE VI

MISCELLANEOUS

     6.1. Failure or Indulgence Not Waiver. No failure or delay on the part of the Holder
hereof in the exercise of any power, right or privilege hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise of any such power, right or privilege preclude
other or further exercise thereof or of any other right, power or privilege. All rights and
remedies existing hereunder are cumulative to, and not exclusive of, any rights or remedies
otherwise available.

     6.2. Notices. Any notice herein required or permitted to be given shall be in writing
and shall be deemed effectively given: (i) upon personal delivery to the party notified, (ii) when

nationally recognized overnight courier, specifying next day delivery, with written verification of
receipt. All communications shall be sent to the Borrower at the address provided in the Purchase

Purchase Agreement for such Holder, with a copy to John E. Tucker, Esq., 825 Third Avenue ,
14th Floor, New York, New York 10022, facsimile number (212) 541-4434, or at such other
address as the Borrower or the Holder may designate by ten days advance written notice to the other
parties hereto. A Notice of Conversion shall be deemed given when made to the Borrower pursuant to
the Purchase Agreement.

     6.3. Amendment Provision. The term “Note” and all reference thereto, as used
throughout this instrument, shall mean this instrument as originally executed, or if later amended
or supplemented, then as so amended or supplemented, and any successor instrument issued pursuant
to Section 3.5 hereof, as it may be amended or supplemented.

     6.4. Assignability. This Note shall be binding upon the Borrower and its successors
and assigns, and shall inure to the benefit of the Holder and its successors and assigns, and may
be assigned by the Holder only pursuant to the requirements of the Purchase Agreement and
applicable federal and state securities laws.

8

 

     6.5. Governing Law. (a) This Note cannot be changed or terminated orally, and shall be
governed by and construed in accordance with the laws of the State of New York, without regard to
principles of conflicts of laws. Any action brought by either party against the other concerning
the transactions contemplated by this Note shall be brought only in any state or federal court
sitting in the Borough of Manhattan, City of New York; provided that nothing contained in this Note
shall be deemed to preclude Holder from bringing suit or taking other legal action in any other
court of competent jurisdiction and nothing shall be deemed to preclude the Borrower from asserting
any defenses or counterclaims in any such actions. Both the Borrower and the individual executing
this Note on behalf of the Borrower agree to submit to the jurisdiction of such courts and waive
trial by jury. The Borrower and the individual executing this Note further consent that any
summons, subpoena or other process or papers (including, without limitation, any notice or motion
or other application to either of the aforementioned courts or a judge thereof) or any notice in
connection with any proceedings hereunder, may be served by registered or certified mail, return
receipt requested, or by personal service provided a reasonable time for appearance is permitted,
or in such other manner as may be permissible under the rules of said courts. The Borrower and the
individual executing this Note waive any objection to jurisdiction and venue of any action
instituted hereon in the Supreme Court for the State of New York, County of New York or the United
States District Court for the Southern District of New York and shall not assert any defense based
on lack of jurisdiction or venue or based upon forum non conveniens in any
action brought in either such court.

     (b) The prevailing party shall be entitled to recover from the other party its reasonable
attorney’s fees and costs; provided, however, that if the parties hereto agree to settle any claim,
action, proceeding or lawsuit brought by one party hereto against the other party hereto, then each
of the parties shall bear its own costs in connection with such claim, action, proceeding or
lawsuit, unless otherwise directed by a court of competent jurisdiction.

     (c) In the event that any provision of this Note is invalid or unenforceable under any
applicable statute or rule of law, then such provision shall be deemed inoperative to the extent
that it may conflict therewith and shall be deemed modified to conform with such statute or rule of
law. Any such provision which may prove invalid or unenforceable under any law shall not affect
the validity or unenforceability of any other provision of this Note.

     6.6. Maximum Payments. Nothing contained herein shall be deemed to establish or
require the payment of a rate of interest or other charges in excess of the maximum permitted by
applicable law. In the event that the rate of interest required to be paid or other charges
hereunder exceed the maximum permitted by such law, any payments in excess of such maximum shall be
credited against amounts owed by the Borrower to the Holder and thus refunded to the Borrower.

     6.7. Security Interest. The holder of this Note has been granted a security interest
in certain assets of the Borrower and of the guarantors of the Note, as more fully described in the
Security Agreement.

     6.8. Construction. Each party acknowledges that its legal counsel participated in the
preparation of this Note and, therefore, stipulates that the rule of construction that ambiguities

9

 

are to be resolved against the drafting party shall not be applied in the interpretation of
this Note to favor any party against the other.
