                                 PROMISSORY NOTE

THEREFORE, FOR VALUE RECEIVED the undersigned, promises to pay to Jerome
Mahoney, the principal sum of One Hundred and Ninety Thousand Dollars
($190,000), at the rate of prime plus 1 percent annum on the unpaid balance
until paid or until default, both principal and interest payable in lawful money
of the United States of America, at SpeechSwitch , Inc. (the "Company") 750
Highway 34, Matawan, New Jersey 07747, or at such place as the legal holder
hereof may designate in writing. It is understood and agreed that additional
amounts may be advanced by the holder hereof as provided in the instruments, if
any, securing this Note and such advances will be added to the principal of this
Note and will accrue interest at the above specified rate of interest from the
date of advance until paid. Such advances may include, in addition to cash
advances: deferred compensation, deferred expense reimbursement, deferred
commissions and income tax reimbursement for the recognition of income upon the
sale of common stock for the purpose of the holder advancing additional funds to
the Company. The principal and interest shall be due and payable as follows: (a)
interest shall accrue monthly on the unpaid balance and shall be paid annually,
and (b) principal shall be payable on demand.

Notwithstanding anything to the contrary herein, the Note holder may elect
prepayment of the principal and/or interest owed pursuant to this Note by
requiring SpeechSwitch , Inc. to issue to Jerome Mahoney, or his assigns either:
(i) one Class B common stock share of the Company par value $.01 per share, for
each dollar owed, (ii) the number of Class A common stock shares of the Company
calculated by dividing (x) the sum of the principal and interest that the Note
holder has decided to have prepaid by (y) eighty percent (80%) of the lowest
issue price of Class A common stock since the first advance of funds under this
Note, or (iii), payment of the principal of this Note, before any repayment of
interest.

Unless otherwise provided, this Note may be prepaid in full or in part at any
time without penalty or premium. Partial prepayments shall be applied to
installments due in reverse order of their maturity.

In the event of (a) default in payment of any installment of principal or
interest hereof as the same becomes due and such default is not cured within ten
(10) days from the due date, or (b) default under the terms of any instrument
securing this Note, and such default is not cured within fifteen (15) days after
written notice to maker, then in either such event the holder may, without
further notice, declare the remainder of the principal sum, together with all
interest accrued thereon, and the prepayment premium, if any, at once due and
payable. Failure to exercise this option shall not constitute a waiver of the
right to exercise the same at any other time. The unpaid principal of this Note
and any part thereof, accrued interest and all other sums due

<PAGE>

under this Note shall bear interest at the rate of prime plus 2 percent per
annum after default until paid.

All parties to this Note, including maker and any sureties, endorsers, or
guarantors, hereby waive protest, presentment, notice of dishonor, and notice of
acceleration of maturity and agree to continue to remain bound for the payment
of principal, interest, and all other sums due under this Note, notwithstanding
any change or changes by way of release, surrender, exchange, modification or
substitution of any security for this Note or by way of any extension or
extensions of time for the payment of principal and interest; and all such
parties waive all and every kind of notice of such change or changes and agree
that the same may be made without notice or consent of any of them.

Upon default, the holder of this Note may employ an attorney to enforce the
holder's rights and remedies and the maker, principal, surety, guarantor and
endorsers of this Note hereby agree to pay to the holder reasonable attorneys
fees, plus all other reasonable expenses incurred by the holder in exercising
any of the holder's right and remedies upon default. The failure to exercise any
such right or remedy shall not be a waiver or release of such rights or remedies
or the right to exercise any of them at another time.

This Note is to be governed and construed in accordance with the laws of the
State of New Jersey.

IN TESTIMONY WHEREOF, each corporate maker has caused this instrument to be
executed in its corporate name by its President, and its corporate seal to be
hereto affixed, all by order of its Board of Directors first duly given, the day

         6. Escrow Agent.

         (a) Duties and Responsibilities. (i) The duties and responsibilities of
the Escrow Agent hereunder shall be limited to those expressly set forth in this
Escrow Agreement, and the Escrow Agent shall not be bound in any way by any
other contract or agreement between the parties hereto, whether or not the
Escrow Agent has knowledge of any such contract or agreement or of the terms or
conditions thereof. In the event that the Escrow Agent shall be uncertain as to
any duties or responsibilities hereunder or shall receive instructions from any
of the parties hereto with respect to the Escrow Property which in the Escrow
Agent's belief are in conflict with any of the provisions of this Escrow
Agreement, the Escrow Agent shall be entitled to refrain from taking any action
until it shall be directed to do so in writing by both parties hereto or by
order of a court of competent jurisdiction in proceedings which the Escrow Agent
or any other party hereto shall be entitled to commence. The Escrow Agent may
act upon the advice of its counsel in taking or refraining from taking any
action hereunder and may act upon any instrument or other writing believed in
good faith to be genuine and to be signed and presented by the proper person or
persons.

                  (ii) The Escrow Agent shall not be responsible for the
genuineness of any signature or document presented to it pursuant to this Escrow
Agreement and may rely conclusively upon and shall be protected in acting upon
any list, advice, judicial order or decree, certificate, notice, request,
consent, statement, instruction or other instrument believed by it in good faith
to be genuine or to be signed or presented by the proper person hereunder, or
duly authorized by such person or properly made. The Escrow Agent shall not be
responsible for any of the agreements contained herein except the performance of
its duties as expressly set forth herein. The duties and obligations of the
Escrow Agent hereunder shall be governed solely by the provisions of this Escrow
Agreement and the Escrow Agent shall have no duties other than the duties
expressly imposed herein and shall not be required to take any action other than
in accordance with the terms hereof. The Escrow Agent shall not be bound by any
notice of, or demand with respect to, any waiver, modification, amendment,
termination, cancellation, rescission or restatement of this Escrow Agreement,
unless in writing and signed by Buyer, Seller and the Shareholder, and, if the
duties of the Escrow Agent are affected thereby, unless Escrow Agent shall have
given its prior written consent thereto.

                                       3
<PAGE>

         (b) Liability. The Escrow Agent shall not be liable to anyone for any
damage, loss or expense incurred as a result of any act or omission of the
Escrow Agent, unless such damage, loss or expense is caused by the Escrow
Agent's willful default or gross negligence. Accordingly, and without limiting
the foregoing, the Escrow Agent shall not incur any such liability with respect
to (i) any action taken or omitted under this Escrow Agreement, or (ii) any
action taken or omitted in reliance upon any instrument, including any written
notice or instruction provided for herein, not only as to its due execution by
an authorized person and as to the validity and effectiveness of such
instrument, but also as to the truth and accuracy of any information contained
therein. Should any issue arise with respect to the delivery or ownership of the
Escrow Property, the Escrow Agent shall have no liability to any party hereto
for retaining dominion and control over the Escrow Property until such issue is
resolved by (i) mutual agreement of the parties; or (ii) final order, decree or
judgment by a court of competent jurisdiction. In no event shall the Escrow
Agent be under any duty whatsoever to institute or defend such proceeding.

         (c) Disputes. In the event of a dispute between any of the parties
hereto sufficient in the discretion of the Escrow Agent to justify its
initiation of legal proceedings, or in the event that Escrow Agent is joined as
a party to a lawsuit by virtue of the fact that it is holding the Escrow
Property, the Escrow Agent may, at its option, either (i) tender the Escrow
Property into the registry or custody of the court of competent jurisdiction
before which such lawsuit is pending, and thereupon be discharged from all
further duties and liabilities under this Escrow Agreement with respect to the
Escrow Property so tendered or (ii) deliver the Escrow Property in accordance
with the court's orders or ultimate disposition of such lawsuit. Any legal
action initiated by the Escrow Agent may be brought in any court as the Escrow
Agent shall determine to have jurisdiction with respect to such matter. Buyer,
Seller and the Shareholder hereby jointly and severally indemnify and hold the
Escrow Agent harmless from and against any damage, losses or expense suffered or
incurred by the Escrow Agent in connection with the exercise by the Escrow Agent
of the options authorized in this paragraph, including but not limited to,
reasonable attorneys' fees and costs and court costs at all trial and appellate
levels.

         (d) Attachment. In the event all or any part of the Escrow Property
shall be attached, garnished or levied upon pursuant to any court order, or the
delivery thereof shall be stayed or enjoined by a court order, or any other
order, judgment or decree shall be made or entered by any court affecting the
Escrow Property or any part hereof or any act of the Escrow Agent, the Escrow
Agent is authorized to obey and comply with all writs, orders, judgments or
decrees so entered or issued by any such court, without the necessity of
inquiring whether such court has jurisdiction; and if the Escrow Agent obeys or
complies with any such writ, order, or decree, the Escrow Agent shall not be
liable to any of the parties hereto or any other person by reason of such
compliance.

         (e) Legal Action. The Escrow Agent shall have no duty to incur any
out-of-pocket expenses or to take any legal action in connection with this
Escrow Agreement or towards its enforcement, or to appear in, prosecute or
defend any action or legal proceeding that would result in or might require it
to incur any cost, expense, loss, or liability, unless and until it shall
receive confirmation and at its option, security, with respect to
indemnification in accordance with Paragraph 6(f) of this Escrow Agreement.

                                       4
<PAGE>

         (f) Indemnification. Without determining or limiting any rights as
between or among Buyer, Seller and the Shareholder, which rights shall exist
outside this Escrow Agreement and not be prejudiced hereby, Buyer, Seller and
the Shareholder jointly and severally hereby agree to indemnify and hold
harmless the Escrow Agent from and against any and all cost, loss, damage,
disbursement, liability, and expense, including reasonable attorneys' fees and
costs, which may be imposed upon or incurred by the Escrow Agent hereunder, or
in connection with the performance of its duties hereunder, including any
litigation arising out of this Escrow Agreement, or involving the subject matter
hereof, except only costs, losses, claims, damages, disbursements, liabilities
and expenses arising out of the Escrow Agent's acts or omissions for which the
Escrow Agent is adjudged willfully malfeasant or grossly negligent by a final
decree, order or judgment of a court of competent jurisdiction from which no
appeal is taken within the applicable appeals period.

         (g) Resignation. The Escrow Agent, or the Escrow Agent's successor
hereinafter appointed, may at any time resign by giving notice in writing to
Buyer, Seller and the Shareholder, and shall be discharged of all further duties
hereunder upon the appointment of a successor escrow agent which shall be
appointed by agreement of each of Buyer, Seller and the Shareholder; provided,
however, that such resigning Escrow Agent shall remain entitled to
indemnification hereunder pursuant to Paragraph 6(f) hereof. If Buyer, Seller
and the Shareholder are unable to agree on a successor escrow agent, either of
such parties may petition a court of competent jurisdiction to appoint one. From
the date upon which the Escrow Agent sends notice of any resignation until the
acceptance by a successor escrow agent appointed as provided herein, the Escrow
Agent's sole obligation hereunder shall be to hold the Escrow Property delivered
to it in accordance with this Agreement. Any such successor escrow agent shall
deliver to Buyer, Seller and the Shareholder a written certificate accepting
such appointment hereunder, and thereupon it shall succeed to all the rights and
duties of the Escrow Agent hereunder and shall be entitled to receive the
benefit of the provisions set forth herein.

         (h) Law Firm Escrow Agent. Buyer, Seller and the Shareholder each
acknowledge and agree that nothing contained herein shall be deemed to prevent
any law firm serving as the Escrow Agent, or as a successor escrow agent, from
acting as counsel for Buyer, Seller or the Shareholder, or any of their
respective stockholders, or any of their respective affiliates, or any other
party in any matter, including resolution of disputes and claims subject to,
arising under or related to the Agreement or this Escrow Agreement, or acting as
an escrow agent on behalf of others.
         (i) Accounting. The Escrow Agent will provide to each of Buyer, Seller
and the Shareholder a written accounting of the investments held in escrow
hereunder and all transactions relating to this Escrow Agreement, including any
distributions of the Escrowed Amount, within twenty (20) business days following
written request of any such Party.

         7. Escrow Agent Fees and Expenses.

         (a) Compensation and Expenses. The Escrow Agent shall be entitled to
reimbursement for its out of pocket costs and expenses and payment of any
amounts to which the Escrow Agent is entitled under the indemnification
provisions contained herein. The costs and expenses of the Escrow Agent,
including reasonable attorneys' fees and costs, shall be borne

                                       5
<PAGE>

jointly and severally by Buyer, Seller and the Shareholder, any amounts owed by
Buyer, Seller and the Shareholder to the Escrow Agent, may be deducted by the
Escrow Agent from the Escrowed Amount before final distribution thereof.

         (b) Reporting. The Shareholder will provide the Escrow Agent with any
IRS Forms W-9 for taxpayer identification number certifications, or Forms W-8
for non-resident alien certifications, as may be appropriate at or prior to the
Closing Date.

         8. Relief.

         In the event litigation is maintained by a party to this Escrow
Agreement against any other party to enforce this Escrow Agreement or to seek
any remedy for breach, then the prevailing party in such litigation shall be
entitled to recover from the non-prevailing party reasonable attorneys' fees and
costs of suit.

         9. Miscellaneous.
