                               W-I-T-N-E-S-S-E-T-H

under the Acquisition Agreement) (all such shares are collectively referred to
herein as the "Payment Shares");

     WHEREAS, in accordance with the Acquisition Agreement, Purchaser has

     WHEREAS, Purchaser has agreed to undertake to register under the Securities
Act (i) the Payment Shares and (ii) the shares of Common Stock issuable upon
exercise of the Warrants (the "Warrant Shares") in accordance with the terms
hereof.

     NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the parties hereto hereby agree as follows:

                                       1
<PAGE>

     1. Definitions. For purposes of this Agreement:

        (a) The terms "register," "registered" and "registration" refer to a
registration effected by preparing and filing a registration statement or
statements or similar documents in compliance with the Securities Act and
pursuant to Rule 415 under the Securities Act or any successor rule providing
for offering securities on a continuous basis ("Rule 415"), and the declaration
or ordering of effectiveness of such registration statement or document by the
Securities and Exchange Commission (the "SEC").

        (b) The term "Registrable Securities" means (i) the Payment Shares and
(ii) the Warrant Shares; provided that, to the extent that Payment Shares or
Warrants are forfeited by Seller in accordance with the terms of the Escrow
Agreement and the Acquisition Agreement, Voxware shall have no obligation
hereunder to register such forfeited Payment Shares or the applicable Warrant
Shares, and such forfeited securities shall not be "Registrable Securities"
hereunder.

        (c) The term "Registration Date" means January 3, 2001.

        (d) The term "Transfer" means, with respect to any Registrable
Securities, directly or indirectly, to sell, assign, transfer, pledge, convey,
distribute, mortgage, encumber, hypothecate or otherwise dispose, whether by
gift, for consideration or for no consideration.

     2. Registration.

        (a) Subject to, and in accordance with, the provisions contained in this
Agreement, Voxware shall use its best efforts to effect the registration under
the Securities Act of all Payment Shares and the Warrant Shares prior to the
Registration Date.

        (b) Voxware shall not be obligated to register any Payment Share or
Warrant Share more than once pursuant to this Agreement.

     3. Obligations of Voxware. In connection with the registration of the
Registrable Securities pursuant to this Agreement, Voxware shall, as
expeditiously as reasonably possible:

        (a) Prepare and file with the SEC a registration statement or statements
or similar documents (each, a "Registration Statement") with respect to the
Registrable Securities, and use its best efforts to cause each Registration
Statement to become effective as soon as reasonably possible after such filing
and on or prior to the Registration Date, and to keep the Registration Statement
effective pursuant to Rule 415 at all times until the Expiration Date (as
defined below), which Registration Statement (including any amendments or
supplements thereto and prospectuses contained therein) shall not contain any
untrue statement of a material fact or omit to state a material

                                       2
<PAGE>

fact required to be stated therein, or necessary to make the statements
therein, in light of the circumstances in which they were made, not misleading.

        (b) Prepare and file with the SEC such amendments (including
post-effective amendments) and supplements to each Registration Statement and
the prospectus used in connection with each Registration Statement as may be
necessary to keep the Registration Statement effective at all times until the
Expiration Date and during such period to comply with the provisions of the
Securities Act with respect to the disposition of all securities covered by the
Registration Statement. The Expiration Date shall be, with respect to each
Registration Statement, the first to occur of (i) the later of (A) nine months
after the effective date of the Registration Statement or (B) if the
Registration Statement covers the resale of Warrant Shares, the date which is
nine months after the Warrant Shares become issuable upon the exercise of
Warrants and (ii) the date on which all of the Registrable Securities covered by
the Registration Statement have been sold or transferred by the selling
stockholders named therein.

        (c) Furnish promptly to Seller such numbers of copies of a prospectus,
including a preliminary prospectus, and all amendments and supplements thereto
and such other documents as Seller may reasonably request in order to facilitate
the disposition of the Registrable Securities.

        (d) Use its reasonable efforts to register and qualify the Registrable
Securities under such other securities or Blue Sky laws of such jurisdiction as
shall be reasonably requested by Seller and prepare and file in those
jurisdictions such amendments (including post-effective amendments) and
supplements and to take such other actions as may be necessary to maintain such
registration and qualification in effect at all times until the Expiration Date,
and to take all other actions necessary or advisable to enable the disposition
of such securities in such jurisdictions, provided that Voxware shall not be
required in connection therewith or as a condition thereto to qualify to do
business, to file a general consent to service of process or to subject itself
to general taxation in any such states or jurisdictions or to provide any
undertaking or make any change in its charter or by-laws which the Board of
Directors of Voxware determines to be contrary to the best interest of Voxware
and its shareholders.

        (e) In the event Voxware selects underwriters for the offering and
Seller consents in its sole discretion to the use of underwriters for the
offering (in which case Stratos shall be deemed to have consented to the use of
underwriters for the offering), enter into and perform its obligations under an
underwriting agreement, in usual and customary form, including, without
limitation, customary indemnification and contribution obligations, with the
managing underwriter of such offering. If the offering is to involve an
underwriting and if the managing underwriter advises Seller and Stratos that
marketing factors require a limitation on the number of Registrable Securities
to be underwritten, the managing underwriter may limit the number of Registrable
Securities to be included in the offering. The number of securities that are
entitled to be included in the offering shall be allocated first to Seller and
Stratos (pro rata based on the number of Warrants held by them) and thereafter
to other persons exercising "piggy-back" registration rights, and

                                       3
<PAGE>

directors, officers and other participating management personnel of Voxware. In
the event that any Payment Shares or Warrant Shares are excluded from the
offering pursuant to this Section 3(e), Voxware's obligations pursuant to
Section 2(a) shall not be deemed to have been met with respect to such Payment
Shares and Warrant Shares so excluded.

        (f) Notify Seller and Stratos, at any time when a prospectus relating to
Registrable Securities is required to be delivered under the Securities Act, of
the happening of any event as a result of which the prospectus included in the
Registration Statement, as then in effect, includes an untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary to make the statements therein not misleading in light of the
circumstances then existing. Voxware shall use its best efforts to promptly
amend or supplement the Registration Statement to correct any such untrue
statement or omission.

        (g) Notify Seller and Stratos (or in the event of an underwritten
offering, the managing underwriters) of the issuance by the SEC of any stop
order suspending the effectiveness of any Registration Statement or the
initiation of any proceedings for that purpose. Voxware will make every
reasonable effort to prevent the issuance of any stop order and, if any stop
order is issued, to obtain the lifting thereof at the earliest possible time.

        (h) Permit a single firm of counsel, designated as selling shareholders'
counsel by Seller, to review each Registration Statement and all amendments and
supplements thereto a reasonable period of time prior to their filing, and shall
not file any document in a form to which such counsel reasonably objects.

        (i) Make generally available to its security holders as soon as
practicable, but not later than 90 days after the close of the period covered
thereby, an earnings statement (in form complying with the provisions of Rule
158 under the Securities Act) covering a twelve-month period beginning not later
than the first day of Voxware's fiscal quarter next following the effective date
of each Registration Statement.

        (j) At the request of Seller, furnish to the underwriters on the date
that Registrable Securities are delivered to the underwriters for sale in
connection with a registration pursuant to this Agreement (i) an opinion, dated
such date, of the counsel representing Voxware for the purposes of such
registration, in form and substance as is customarily given to underwriters in
an underwritten public offering, addressed to the underwriters and (ii) a
letter, dated such date, from the independent certified public accountants of
Voxware, in form and substance as is customarily given by independent certified
public accountants to underwriters in an underwritten public offering, addressed
to the underwriters.

        (k) Make available for inspection by Seller, any underwriters
participating in the offering pursuant to a Registration Statement and the
counsel, accountants or other agents retained by Seller or any such underwriter
(collectively the "Inspectors"), all pertinent financial and other records,
corporate documents and properties of Voxware (collectively, the "Records"), and

                                       4
<PAGE>

cause Voxware's officers, directors and employees to supply all information
reasonably requested by Seller or any such underwriters in connection with the
Registration Statement. Records and other information which Voxware determines
in good faith to be confidential, and of which determination the Inspectors are
so notified, shall not be disclosed by the Inspectors (or used for any purpose
unrelated to the offering) unless (i) the disclosure of such Records is
necessary in the written opinion of counsel to Seller delivered to Voxware (such
counsel being reasonably satisfactory to Voxware) to comply with the Federal
securities laws, (ii) the disclosure of such Records is necessary to avoid or
correct a misstatement or omission in the Registration Statement, (iii) the
release of such Records is ordered pursuant to a subpoena or other order from a
court of competent jurisdiction, or (iv) the information in such Records has
been made generally available to the public other than by disclosure in
violation of this or any other agreement. Voxware shall not be required to
disclose any confidential information or other Records to any Inspectors until
and unless the Inspectors shall have entered into reasonable confidentiality
agreements (in the form and substance reasonably satisfactory to Voxware) with
Voxware with respect thereto; provided, however, that if the opinion identified
in the preceding sentence is delivered to Voxware, then Seller shall be
permitted to disclose in the Registration Statement the Records covered by such
opinion. Seller agrees that it shall, upon learning that disclosure of such
Records is sought in a court of competent jurisdiction or through other means,
give prompt notice to Voxware and allow Voxware, at its expense, to undertake
appropriate action to prevent disclosure of the Records deemed confidential.

        (l) If the Common Stock is then listed on a national securities
exchange, use its best efforts to cause the Registrable Securities to be listed
on such exchange if the listing of such Registrable Securities is then permitted
under the rules of such exchange, or if the Common Stock is not then listed on a
national securities exchange, use its best efforts to facilitate the quotation
of the Common Stock on NASDAQ.

        (m) Provide a transfer agent and registrar, which may be a single
entity, for the Registrable Securities not later than the effective date of the
Registration Statement.

        (n) Take all actions reasonably necessary to facilitate the timely
preparation and delivery of certificates (not bearing any restrictive legend)
representing the Registrable Securities to be sold pursuant to the Registration
Statement and to enable such certificates to be in such denominations and
registered in such names as Seller or any underwriters may reasonably request.

        (o) Take all other actions reasonably necessary to expedite and
facilitate disposition by Seller and Stratos of the Registrable Securities
pursuant to the Registration Statement.

        (p) Notwithstanding anything contained in this Section 3 to the
contrary, Voxware shall have no obligation pursuant to Sections 2 or 3 to
continue to maintain the accuracy and effectiveness of a registration of
Registrable Securities held by Seller after the date on which both (i) Seller
would be entitled to sell under Rule 144 within a single three-month period (or
such other unitary period prescribed under Rule 144 as may be provided by
amendment thereof) all of the

                                       5
<PAGE>

Registrable Securities then held by Seller, and (ii) the number of Registrable
Securities held by Seller is within the volume limitations under paragraph (e)
of Rule 144 (calculated as if Seller were an affiliate within the meaning of
Rule 144).

     4. Obligations of Seller and Stratos. In connection with each registration
of the Registrable Securities, Seller and Stratos shall have the following
obligations:

        (a) It shall be a condition precedent to the obligations of Voxware to
take any action pursuant to this Agreement with respect to Seller and Stratos
that each of Seller and Stratos shall furnish to Voxware such information
regarding itself, the Registrable Securities held by it, and the intended method
of disposition of such securities as shall be reasonably required to effect the
registration of the Registrable Securities and shall execute such documents in
connection with such registration as Voxware may reasonably request.

        (b) Each of Seller and Stratos, by its acceptance of the Registrable
Securities, agrees to cooperate with Voxware in connection with the preparation
and filing of any Registration Statement hereunder.

        (c) In the event underwriters are selected by Voxware for any offering
consented to by Seller in accordance with Section 3(e), each of Seller and
Stratos agrees to enter into and perform its obligations under an underwriting
agreement, in usual and customary form, including, without limitation, customary
indemnification and contribution obligations and market stand-off obligations,
with the managing underwriter of such offering and to take such other actions as
are reasonably required in order to expedite or facilitate the disposition of
the Registrable Securities.

        (d) Each of Seller and Stratos agrees that, upon receipt of any notice
from Voxware of the happening of any event of the kind described in Section
3(f), Seller and Stratos will immediately discontinue disposition of Registrable
Securities pursuant to the Registration Statement covering such Registrable
Securities until their receipt of the copies of the supplemented or amended
prospectus contemplated by Section 3(f) and, if so desired by Voxware, they
shall deliver to Voxware (at the expense of Voxware) or destroy (and deliver to
Voxware a certificate of such destruction) all copies, other than permanent file
copies then in their possession, of the prospectus covering such Registrable
Securities current at the time of receipt of such notice.

        (e) Neither Seller nor Stratos may participate in any underwritten
registration hereunder unless Seller and Stratos (i) agree to sell their
Registrable Securities on the basis provided in any underwriting arrangements
approved by Seller entitled hereunder to approve such arrangements, (ii)
complete and execute all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents reasonably required under the terms
of such underwriting arrangements and (iii) agree to pay their pro rata portion
of all underwriting discounts and commissions.

                                       6
<PAGE>

     5. Expenses of Registration. All expenses, other than underwriting
discounts and commissions which are incurred in connection with registration,
filings, or qualifications pursuant to Sections 2 and 3, including, without
limitation, all registration, listing, filing and qualification fees, printers
and accounting fees, the fees and disbursements of legal counsel (including fees
and expenses of a single counsel for all sellers of Registrable Securities in
such registration), shall be borne by Voxware.

     6. Indemnification. In the event any Registrable Securities are included in
a Registration Statement under this Agreement:

        (a) To the extent permitted by law, Voxware will indemnify and hold
harmless Seller and Stratos, their directors, their officers who sign the
Registration Statement, each person, if any, who controls Seller or Stratos, any
underwriter (as defined in the Securities Act) for Seller or Stratos and each
person, if any, who controls any such underwriter within the meaning of the
Securities Act or the Securities Exchange Act of 1934, as amended (the "1934
Act"), against any losses, claims, damages, expenses or liabilities (joint or
several) to which any of them may become subject under the Securities Act, the
1934 Act or otherwise, insofar as such losses, claims, damages, expenses or
liabilities (or actions or proceedings, whether commenced or threatened, in
respect thereof) arise out of or are based upon any of the following statements,
omissions or violations (collectively, a "Violation"): (i) any untrue statement
or alleged untrue statement of a material fact contained in the Registration
Statement, including any preliminary prospectus or final prospectus contained
therein or any amendments or supplements thereto, (ii) the omission or alleged
omission to state therein a material fact required to be stated therein, or
necessary to make the statements therein, in light of the circumstances in which
they were made, not misleading or (iii) any violation or alleged violation by
Voxware of the Securities Act, the 1934 Act, any state securities law or any
rule or regulation promulgated under the Securities Act, the 1934 Act or any
state securities law; and subject to the restrictions set forth in Section 6(c)
with respect to the number of legal counsel, Voxware will reimburse Seller,
Stratos and each such underwriter or controlling person, promptly as such
expenses are incurred, for any legal or other expenses reasonably incurred by
them in connection with investigating or defending any such loss, claim, damage,
liability, action or proceeding; provided, however, that the indemnity agreement
contained in this subsection 6(a) (I) shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the prior written consent of Voxware, which
consent shall not be unreasonably withheld, (II) shall not apply to any such
case for any such loss, claim, damage, liability or action arising out of or
based upon a Violation which occurs in reasonable reliance upon and in
conformity with written information furnished expressly for use in connection
with such registration by Seller, Stratos or any such underwriter or controlling
person, as the case may be, and (III) with respect to any preliminary
prospectus, shall not inure to the benefit of any person from whom the person
asserting any such claim purchased the Registrable Securities that are the
subject thereof (or to the benefit of any person controlling such person) if the
untrue statement or omission of material fact contained the preliminary
prospectus was corrected in the prospectus, as then

                                       7
<PAGE>

amended or supplemented. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of Seller, Stratos or any
such underwriter or controlling person and shall survive the transfer of the
Registrable Securities by Seller or Stratos pursuant to Section 8.

        (b) To the extent permitted by law, Seller and Stratos will indemnify
and hold harmless, to the same extent and in the same manner set forth in
Section 6(a), Voxware, each of its directors, each of its officers who have
signed the Registration Statement, each person, if any, who controls Voxware
within the meaning of the Securities Act or the 1934 Act, any underwriter and
any other stockholder selling securities pursuant to the Registration Statement
or any of its directors or officers or any person who controls such holder or
underwriter, against any losses, claims, damages or liabilities (joint or
several) to which any of them may become subject, under the Securities Act, the
1934 Act or other federal or state law, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon
any Violation, in each case to the extent (and only to the extent) that such
Violation occurs in reliance upon and in conformity with written information
furnished by Seller or Stratos expressly for use in connection with such
registration; and Seller and Stratos will reimburse any legal or other expenses
reasonably incurred by any of them in connection with investigating or defending
any such loss, claim, damage, liability or action; provided, however, that
Seller and Stratos shall be liable under this paragraph for only that amount of
losses, claims, damages and liabilities as does not exceed the proceeds to
Seller or Stratos as a result of the sale of Registrable Securities pursuant to
such registration. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of such indemnified party
and shall survive the transfer of the Registrable Securities by Seller or
Stratos pursuant to Section 8. Voxware shall be entitled to receive indemnities
from underwriters, selling brokers, dealer managers and similar securities
industry professionals participating in the distribution, to the same extent as
provided above, with respect to information about such persons so furnished in
writing by such persons expressly for inclusion in the Registration Statement.

        (c) Promptly after receipt by an indemnified party under this Section 6
of notice of the commencement of any action (including any governmental action),
such indemnified party will, if a claim in respect thereof is to be made against
any indemnifying party under this Section 6, deliver to the indemnifying party a
written notice of the commencement thereof, and the indemnifying party shall
have the right to participate in, and, to the extent the indemnifying party so
desires, jointly with any other indemnifying party similarly noticed, to assume
control of the defense thereof with counsel satisfactory to the indemnifying
parties; provided, however, that an indemnified party shall have the right to
retain its own counsel, with the fees and expenses to be paid by the
indemnifying party, if, in the reasonable opinion of counsel for the
indemnifying party, representation of such indemnified party by the counsel
retained by the indemnifying party would be inappropriate due to actual or
potential differing interests between such indemnified party and any other party
represented by such counsel in such proceeding. Voxware shall pay for only one
legal counsel for Seller and Stratos; such legal counsel shall be selected by
Seller. The failure to deliver written notice to the indemnifying party within a
reasonable time of the commencement of any such action shall relieve such
indemnifying party of any liability to the indemnified party under this Section
6 only to the extent prejudicial to its ability to defend such action, but the
omission so to

                                       8
<PAGE>

deliver written notice to the indemnifying party will not relieve it of any
liability that it may have to any indemnified party otherwise than under this
Section 6. The indemnification required by this Section 6 shall be made by
periodic payments of the amount thereof during the course of the investigation
or defense, promptly as such expense, loss, damage or liability is incurred and
is due and payable.

        (d) To the extent any indemnification by an indemnifying party is
prohibited or limited by law, the indemnifying party agrees to make the maximum
contribution with respect to any amounts for which it would otherwise be liable
under this Section 6 to the extent permitted by law; provided that (i) no
contribution shall be made under circumstances where the maker would not have
been liable for indemnification under the fault standards set forth in this
Section 6, (ii) no seller of Registrable Securities guilty of fraudulent
misrepresentation (within the meaning of Section 11 of the Securities Act) shall
be entitled to contribution from any seller of Registrable Securities who was
not guilty of such fraudulent misrepresentation and (iii) contribution by any
seller of Registrable Securities shall be limited in amount to the net amount of
proceeds received by such seller from the sale of such Registrable Securities.

     7. Reports Under Securities Exchange Act of 1934. With a view to making
available to Seller and Stratos the benefits of Rule 144 promulgated under the
Securities Act and any other rule or regulation of the SEC that may at any time
permit Seller and Stratos to sell securities of Voxware to the public without
registration, Voxware agrees to:

        (a) make and at all times keep public information available, as those
terms are understood and defined in Rule 144 under the Securities Act;

        (b) file with the SEC in a timely manner all reports and other documents
required of Voxware under the Securities Act and the 1934 Act; and

        (c) furnish to Seller and Stratos, so long as Seller owns any
Registrable Securities, forthwith upon request (i) a written statement by
Voxware that it has complied with the reporting requirements of Rule 144 under
the Securities Act, the Securities Act and the 1934 Act, (ii) a copy of the most
recent annual or quarterly report of Voxware and such other reports and
documents so filed by Voxware and (iii) such other information as may be
reasonably requested in availing Seller and Stratos of any rule or regulation of
the SEC which permits the selling of any such securities without registration.

     8. Assignment of Registration Rights. The rights to have Voxware register
securities granted to Seller and Stratos by Voxware hereunder may be transferred
or assigned in connection with a transfer of the Registrable Securities which is
not in violation of this Agreement (other than to a transferee pursuant to Rule
144 or pursuant to a Registration Statement); provided that, Voxware is given
written notice at the time of said transfer or assignment stating the name and
address of said transferee or assignee and identifying the Registrable
Securities with respect to which such registration rights are being transferred
or assigned, and provided further that the transferee or

                                       9
<PAGE>

assignee of such rights assumes the obligations of Seller or Stratos under this
Agreement with respect to the transferred Registrable Securities, and; provided
further, that said transferee or assignee is not a competitor or an affiliate of
a competitor of Voxware.

     9. Transfer Restrictions.

        (a) The holder of each certificate representing Registrable Securities
by acceptance thereof agrees to comply in all respects with the provisions of
this Agreement. Prior to any proposed Transfer of any Registrable Securities
(other than (i) a Transfer not involving a change in beneficial ownership, (ii)
in transactions involving the distribution without consideration of Registrable
Securities by Seller to any of its stockholders in dissolution, (iii) in
transactions involving the transfer without consideration of Registrable
Securities by any Person during his or her lifetime by way of gift or on death
by will or intestacy, (iv) in transactions involving the transfer or
distribution of Registrable Securities by a corporation to any subsidiary,
parent or affiliate of such corporation, (v) in transactions in compliance with
Rule 144, (vi) Transfers under and pursuant to any Registration Statement or
(vii) in transactions involving the Transfer of Registrable Securities by a
partnership or limited liability company to its partners or members; provided,
that, in the case of (i), (ii), (iii), (iv), (vi) and (vii), the transferee
agrees to be bound by the terms of this Agreement as if it were Seller
hereunder), unless there is in effect a registration statement under the
Securities Act covering the proposed Transfer, the holder thereof shall give
written notice to Voxware of such holder's intention to effect such Transfer,
sale, assignment or pledge. Each such notice shall describe the manner and
circumstances of the proposed Transfer, sale, assignment or pledge in suffi
cient detail, and if requested by Voxware shall be accompanied at such holder's
expense by either (i) an unqualified written opinion of legal counsel who shall
be reasonably satisfactory to Voxware, addressed to Voxware and reasonably
satisfactory in form and substance to Voxware's counsel, to the effect that the
proposed transfer of the Registrable Securities may be effected without
registration under the Securities Act and applicable state securities laws, or
(ii) a "no-action" letter from the SEC to the effect that the distribution of
such securities without registration will not result in a recommendation by the
staff of the SEC that action be taken with respect thereto, whereupon the holder
of such Registrable Securities shall be entitled to transfer such Registrable
Securities in accordance with the terms of the notice delivered by the holder to
Voxware. Each certificate evidencing the Registrable Securities transferred as
above provided

                                       10
<PAGE>

shall bear the appropriate restrictive legend set forth below, except that such
certificate shall not bear such restrictive legend if in the opinion of counsel
for Voxware such legend is not required in order to establish compliance with
any provisions of the Securities Act or applicable state securities laws.

        (b) Notwithstanding anything herein to the contrary, Seller agrees that
it shall not Transfer Payment Shares, Warrants or Warrant Shares and Stratos
agrees that it shall not Transfer any Warrants or Warrant Shares until the
Registration Date except in Transfers described in clauses (i), (ii), (iii),
(iv), (vi) and (vii) of Section 9(a) above.

        (c) Each certificate representing the Warrants, the Payment Shares or
the Warrant Shares or any other securities issued upon any stock split, stock
dividend, recapitalization, merger, consolidation or similar event shall (unless
