administrators, attorneys, agents, representatives, successors (including
successors to the business by way of asset purchase), assigns, and all persons
acting by, through, or in concert with them (collectively, the "Castle Creek

cross-claim, third-party action, arbitration or mediation, demand, loss of
services, compensation, charges, complaints, debts, obligations, promises or

trespass, negligence, or strict liability), loss of quality of life, property
damage (including but not limited to injury to property) or liabilities of any

(by means of any individual or group charges or complaints or in any other
manner) against Castle Creek or any other Castle Creek Releasees before any
court or other agency of federal, state or local government, or any other forum.

     Voxware warrants and represents to the best of Voxware's knowledge that no

future claim, demand, order, directive, action, suit, cause of action, request
for declaratory relief, cross-claim, third-party action, arbitration or

negligence, or strict liability), loss of quality of life, property damage
(including but not limited to injury to property) or liabilities of any kind,
whether at law or in equity, whether presently known, unknown or unknowable, or
any other statutory, regulatory, administrative or common law cause of action of
any sort or nature from the beginning of the world to the date hereof, which
Castle Creek may have or claim to have against the Voxware Releasees as follows,
(i) in the case of the Voxware Company Releasees, arising out of, from or
relating in any way to any occurrence up to and including the date of execution
of this Settlement Agreement (the "Castle Creek Company Claims"), including
without limitation any claims relating to the terms of the Series B Stock, the
Series D Stock or the Financing, and, (ii) in the case of Voxware Investor
Releasees, arising out of, from or relating in any way to the terms of the
Series B Stock or the Series D Stock or any occurrence otherwise arising out of,
from or relating in any way to the Financing (the "Castle Creek Investor
Claims", collectively with the Castle Creek Company Claims, shall be referred to
as the "Castle Creek Claims"); provided, however, that nothing herein shall be
deemed to limit (a) Castle Creek's rights or claims under the Series D Stock
Purchase Agreement arising out of, from or relating in any way to any occurrence
after the date of execution of this Settlement Agreement or (b) Castle Creek's
rights or claims under the other transaction documents related to the Financing
to which Voxware is a party or otherwise bound, including without limitation the
Amended and Restated Charter, arising out of, from or relating in any way to any
occurrence after the Closing.

     Upon the date of Closing, Castle Creek forever waives, surrenders and
abandons any and all Castle Creek Claims, on its own behalf and on behalf of all
persons and entities acting through or under, or in control of it or controlled
by it. Castle Creek hereby expressly assumes

                                       7

<PAGE>

the risk that there may be Castle Creek Claims against Voxware or other Voxware
Releasees that are unknown or unknowable to it and that the damages or costs
sustained by them as a result of any released Castle Creek Claims may be greater
than each currently realizes, that the damages may increase in amount or in
severity over time, that the injuries, damages, and/or claims may be
progressive, cumulative, unknown and/or unforeseeable, and that there may be
hidden, unknown and unknowable damages or costs. Castle Creek hereby
acknowledges that it is aware that it may hereafter discover facts in addition
to or different from those it now knows or believes to be true with respect to
the subject matter of the Castle Creek Claims, but that it is its intention
hereby to fully, finally and forever to settle and release any and all matters,
disputes and differences, known or unknown, suspected or unsuspected, which do
now or may in the future exist and that, in furtherance of such intention,
releases hereby given shall be and remain in effect as full and complete general
releases, notwithstanding the discovery or existence of any such additional or
different facts.

     Castle Creek warrants and represents that, other than the Litigation, it
has not filed any Castle Creek Claims (by means of any individual or group
charges or complaints or in any other manner) against Voxware or any other
Voxware Releasees before any court or other agency of federal, state or local
government, or any other forum.

     Castle Creek warrants and represents that, to the best of Castle Creek's
knowledge, other than the Litigation, no Castle Creek Claim has been asserted or
filed against Voxware or any other Voxware Releasees by any person or entity
acting through or under, in control of or controlled by Castle Creek.

     9.   Covenant Not to Sue. The actions to be taken in furtherance of this
Settlement Agreement shall resolve any and all Voxware Claims and Castle Creek
Claims. Upon the

                                       8

<PAGE>

Closing: (a) Voxware covenants that neither Voxware, nor any entity who controls
it or is controlled by it, shall sue, or take any civil or administrative
action, or bring any other proceeding against Castle Creek or any other Castle
Creek Releasees to seek relief with respect to any Voxware Claims; and (b)
Castle Creek covenants that neither Castle Creek nor any entity who controls it
or is controlled by it shall sue, or take any civil or administrative action, or
bring any other proceeding against Voxware or any other Voxware Releasees to
seek relief with respect to any Castle Creek Claims. The Parties further
expressly covenant and agree that they will not participate in any charge or
complaint that may be made by and person or organization on their respective
behalf.

     10.  Foreclosure from Claims Against Third Parties. Except as specifically
set forth herein, the Parties, each on its own behalf and on behalf of all
persons and entities acting through or under, in control of it or controlled by
it, do hereby agree: (a) that this Settlement Agreement affirmatively and
expressly forecloses Voxware and all persons and entities acting through or
under, in control of it or controlled by it from prosecuting Voxware Claims
against other third persons or entities, including all Castle Creek Releasees;
and (b) that this Settlement Agreement affirmatively and expressly forecloses
Castle Creek and all persons and entities acting through or under, in control of
or controlled by it, from prosecuting Castle Creek Claims against other third
persons or entities, including all Voxware Releasees. Except as specifically set
forth herein, the Parties further expressly covenant and agree forever to
refrain from bringing any suit or proceeding at law or in equity against third
parties or entities relating to any Voxware Claims or Castle Creek Claims.
Notwithstanding the foregoing or any other provision of this Settlement
Agreement, any Party shall have the right to assert a Voxware Claim or a Castle
Creek Claim against any Castle Creek Releasee or Voxware Releasee, respectively,
solely in the event that

                                       9

<PAGE>

such Castle Creek Releasee or Voxware Releasee asserts a Castle Creek Claim or a
Voxware Claim against such Party in a court of competent jurisdiction.

     11.  Enforcement. Each of the Parties acknowledge and agree that
irreparable damage would occur if any of the provisions of this Settlement
Agreement were not performed in accordance with their specific terms or were
otherwise breached and that monetary damages would be an inadequate remedy
therefore. Accordingly, each of the Parties will be entitled to seek an
injunction or injunctions to prevent breaches of this Settlement Agreement and
to enforce specifically its provisions in any foreign court, court of the United
States or any state court having jurisdiction, this being in addition to any
other remedy to which the Parties may be entitled at law or in equity.

     12.  Assignment. Voxware and Castle Creek each represent and warrant that,
as of the date hereof and the Closing, neither Party has or will have assigned,
transferred, conveyed, or purported to assign, transfer or convey any Voxware
Claims or Castle Creek Claims, respectively, to any other person or entity, nor
shall they hereafter do so.

     13.  No Admission. By entering into this Settlement Agreement, the Parties
do not intend to make, nor shall they be deemed to have made, any admission of
any kind. Nothing contained in this Settlement Agreement shall be construed as
an admission by any Party as to the merit or lack of merit of any particular
theory relating to the payment of Voxware Claims or Castle Creek Claims, as
applicable. Statements made in the course of negotiations have been and shall be
without prejudice to the rights of the Parties in any disputes or transactions
with any other persons or entities not a party to this Settlement Agreement.

     14.  Protection Afforded. In addition to any confidentiality provisions
contained herein and not by way of limitation thereof, this Settlement Agreement
shall be deemed to fall

                                       10

<PAGE>

within the protection afforded compromises and offers to compromise by Rule 408
of the Federal Rules of Evidence and any similar law provision.

     15.  Notices. Any statements, communications or notices to be provided
pursuant to this Settlement Agreement shall be in writing and shall be sent by
certified mail, return receipt requested, postage prepaid, to the attention of
the Parties at the addresses indicated below, until such time as notice of any
change of person to be notified or change of address is forwarded to all

consistent with, applicable law.

     19.  No Waiver. No failure or delay on the part of any Party to exercise

right or privilege preclude other or further exercise thereof or of any other
right, power or privilege.

     20.  Successors and Assigns; Third Party Rights. This Settlement Agreement
shall bind the successors and assigns of the Parties, and inure to the benefit
of any successor or assign of any of the Parties; provided, however, that no

receipt requested, at the addresses specified or determined in accordance with
the provisions of Section 15, and service so made shall be deemed completed on
