                                  VOXWARE, INC.

                            2003 STOCK INCENTIVE PLAN

1.   Purpose

     The purpose of this 2003 Stock Incentive Plan (the "Plan") of Voxware,
Inc., a Delaware corporation (the "Company"), is to advance the interests of the
Company's stockholders by enhancing the Company's ability to attract, retain and
motivate persons who make (or are expected to make) important contributions to
the Company by providing such persons with equity ownership opportunities and
performance-based incentives and thereby better aligning the interests of such
persons with those of the Company's stockholders. Except where the context
otherwise requires, the term "Company" shall include any of the Company's
present or future parent or subsidiary corporations as defined in Sections
424(e) or (f) of the Internal Revenue Code of 1986, as amended, and any
regulations promulgated thereunder (the "Code") and any other business venture
(including, without limitation, joint venture or limited liability company) in
which the Company has a controlling interest, as determined by the Board of
Directors of the Company (the "Board").

2.   Eligibility

     All of the Company's employees, officers, directors, consultants and
advisors are eligible to be granted options or restricted stock awards (each, an
"Award") under the Plan. Each person who has been granted an Award under the
Plan shall be deemed a "Participant".

3.   Administration and Delegation

     (a) Administration by Board of Directors. The Plan will be administered by
the Board. The Board shall have authority to grant Awards and to adopt, amend
and repeal such administrative rules, guidelines and practices relating to the
Plan as it shall deem advisable. The Board may correct any defect, supply any
omission or reconcile any inconsistency in the Plan or any Award in the manner
and to the extent it shall deem expedient to carry the Plan into effect and it
shall be the sole and final judge of such expediency. All decisions by the Board
shall be made in the Board's sole discretion and shall be final and binding on
all persons having or claiming any interest in the Plan or in any Award. No
director or person acting pursuant to the authority delegated by the Board shall
be liable for any action or determination relating to or under the Plan made in
good faith.

     (b) Appointment of Committees. To the extent permitted by applicable law,
the Board may delegate any or all of its powers under the Plan to one or more
committees or subcommittees of the Board (a "Committee"). All references in the
Plan to the "Board" shall mean the Board or a Committee of the Board to the
extent that the Board's powers or authority under the Plan have been delegated
to such Committee.

4.   Stock Available for Awards

     (a) Number of Shares. Subject to adjustment under Section 7, Awards may be
made under the Plan for up to 90,000,000 shares of common stock, $0.001 par
value per share, of the Company (the "Common Stock"). If any Award expires or is
terminated, surrendered or canceled without having been fully exercised or is
forfeited in whole or in part (including as the result of shares of Common Stock
subject to such Award being repurchased by the Company at the original issuance
price pursuant to a contractual repurchase right) or results in any Common Stock
not being issued, the unused Common Stock covered by such Award shall again be
available for the grant of Awards under the Plan, subject, however, in the case
of Incentive Stock Options (as hereinafter defined), to any limitations under
the Code. Shares issued under the Plan may consist in whole or in part of
authorized but unissued shares or treasury shares.

     (b) Per-Participant Limit. Subject to adjustment under Section 7, the
maximum number of shares of Common Stock with respect to which Awards may be
granted to any Participant under the Plan shall be 30,000,000 per calendar year.
The per-Participant limit described in this Section 4(b) shall be construed and
applied consistently with Section 162(m) of the Code ("Section 162(m)").

5.   Stock Options

     (a) General. The Board may grant options to purchase Common Stock (each, an
"Option") and determine the number of shares of Common Stock to be covered by
each Option, the exercise price of each Option and the conditions and
limitations applicable to the exercise of each Option, including conditions
relating to applicable federal or state securities laws, as it considers
necessary or advisable. An Option which is not intended to be an Incentive Stock
Option (as hereinafter defined) shall be designated a "Nonstatutory Stock
Option".

     (b) Incentive Stock Options. An Option that the Board intends to be an
"incentive stock option" as defined in Section 422 of the Code (an "Incentive
Stock Option") shall only be granted to employees of Voxware, Inc., any of
Voxware, Inc.'s present or future parent or subsidiary corporations as defined
in Sections 424(e) or (f) of the Code, and any other entities the employees of
which are eligible to receive Incentive Stock Options under the Code, and shall
be subject to and shall be construed consistently with the requirements of
Section 422 of the Code. The Company shall have no liability to a Participant,
or any other party, if an Option (or any part thereof) that is intended to be an
Incentive Stock Option is not an Incentive Stock Option.

     (c) Exercise Price. The Board shall establish the exercise price at the
time each Option is granted and specify it in the applicable option agreement.

     (d) Duration of Options. Each Option shall be exercisable at such times and
subject to such terms and conditions as the Board may specify in the applicable
option agreement provided, however, that no Option will be granted for a term in
excess of 10 years.

     (e) Exercise of Option. Options may be exercised by delivery to the Company
of a written notice of exercise signed by the proper person or by any other form
of notice (including

                                       -2-

<PAGE>

electronic notice) approved by the Board together with payment in full as
specified in Section 5(f) for the number of shares for which the Option is
exercised.

     (f) Payment Upon Exercise. Common Stock purchased upon the exercise of an
Option granted under the Plan shall be paid for as follows:

          (1) in cash or by check, payable to the order of the Company;

          (2) except as the Board may, in its sole discretion, otherwise provide
in an option agreement, by (i) delivery of an irrevocable and unconditional
undertaking by a creditworthy broker to deliver promptly to the Company
sufficient funds to pay the exercise price and any required tax withholding or
(ii) delivery by the Participant to the Company of a copy of irrevocable and
unconditional instructions to a creditworthy broker to deliver promptly to the
Company cash or a check sufficient to pay the exercise price and any required
tax withholding;

          (3) when the Common Stock is registered under the Securities Exchange
Act of 1934 (the "Exchange Act"), by delivery of shares of Common Stock owned by
the Participant valued at their fair market value as determined by (or in a
manner approved by) the Board in good faith ("Fair Market Value"), provided (i)
such method of payment is then permitted under applicable law and (ii) such
Common Stock, if acquired directly from the Company was owned by the Participant
at least six months prior to such delivery; or

          (4) by any combination of the above permitted forms of payment.

     (g) Substitute Options. In connection with a merger or consolidation of an
entity with the Company or the acquisition by the Company of property or stock
of an entity, the Board may grant Options in substitution for any options or
other stock or stock-based awards granted by such entity or an affiliate
thereof. Substitute Options may be granted on such terms as the Board deems
appropriate in the circumstances, notwithstanding any limitations on Options
contained in the other sections of this Section 5 or in Section 2.

6.   Restricted Stock.

     (a) Grants. The Board may grant Awards entitling recipients to acquire
shares of Common Stock, subject to the right of the Company to repurchase all or
part of such shares at their issue price or other stated or formula price (or to
require forfeiture of such shares if issued at no cost) from the recipient in
the event that conditions specified by the Board in the applicable Award are not
satisfied prior to the end of the applicable restriction period or periods
established by the Board for such Award (each, a "Restricted Stock Award").

     (b) Terms and Conditions. The Board shall determine the terms and
conditions of any such Restricted Stock Award, including the conditions for
repurchase (or forfeiture) and the issue price, if any.

     (c) Stock Certificates. Any stock certificates issued in respect of a
Restricted Stock Award shall be registered in the name of the Participant and,
unless otherwise determined by the Board, deposited by the Participant, together
with a stock power endorsed in blank, with the

                                       -3-

<PAGE>

Company (or its designee). At the expiration of the applicable restriction
periods, the Company (or such designee) shall deliver the certificates no longer
subject to such restrictions to the Participant or if the Participant has died,
to the beneficiary designated, in a manner determined by the Board, by a
Participant to receive amounts due or exercise rights of the Participant in the
event of the Participant's death (the "Designated Beneficiary"). In the absence
of an effective designation by a Participant, Designated Beneficiary shall mean
the Participant's estate.

7.   Adjustments for Changes in Common Stock and Certain Other Events

     (a) Changes in Capitalization. In the event of any stock split, reverse
stock split, stock dividend, recapitalization, combination of shares,
reclassification of shares, spin-off or other similar change in capitalization
or event, or any distribution to holders of Common Stock other than a normal
cash dividend, (i) the number and class of securities available under this Plan,
(ii) the per-Participant limit set forth in Section 4(b), (iii) the number and
class of securities and exercise price per share subject to each outstanding
Option, and (iv) the repurchase price per share subject to each outstanding
Restricted Stock Award shall be appropriately adjusted by the Company (or
substituted Awards may be made, if applicable) to the extent the Board shall
determine, in good faith, that such an adjustment (or substitution) is necessary
and appropriate. If this Section 7(a) applies and Section 7(c) also applies to
any event, Section 7(c) shall be applicable to such event, and this Section 7(a)
shall not be applicable.

     (b) Liquidation or Dissolution. In the event of a proposed liquidation or
dissolution of the Company, the Board shall upon written notice to the
Participants provide that all then unexercised Options will (i) become
exercisable in full as of a specified time at least 10 business days prior to
the effective date of such liquidation or dissolution and (ii) terminate
effective upon such liquidation or dissolution, except to the extent exercised
before such effective date. The Board may specify the effect of a liquidation or
dissolution on any Restricted Stock Award granted under the Plan at the time of
the grant.

     (c) Reorganization Events.

          (1) Definition. A "Reorganization Event" shall mean: (a) any merger or
consolidation of the Company with or into another entity as a result of which
all of the Common Stock of the Company is converted into or exchanged for the
right to receive cash, securities or other property or (b) any exchange of all
of the Common Stock of the Company for cash, securities or other property
pursuant to a share exchange transaction.

          (2) Consequences of a Reorganization Event on Options. Upon the
occurrence of a Reorganization Event, or the execution by the Company of any
agreement with respect to a Reorganization Event, the Board shall provide that
all outstanding Options shall be assumed, or equivalent options shall be
substituted, by the acquiring or succeeding corporation (or an affiliate
thereof). For purposes hereof, an Option shall be considered to be assumed if,
following consummation of the Reorganization Event, the Option confers the right
to purchase, for each share of Common Stock subject to the Option immediately
prior to the consummation of the Reorganization Event, the consideration
(whether cash, securities or other property) received as a result of the
Reorganization Event by holders of Common Stock for each share of Common Stock
held immediately prior to the consummation of the Reorganization Event (and if
holders

                                       -4-

<PAGE>

were offered a choice of consideration, the type of consideration chosen by the
holders of a majority of the outstanding shares of Common Stock); provided,
however, that if the consideration received as a result of the Reorganization
Event is not solely common stock of the acquiring or succeeding corporation (or
an affiliate thereof), the Company may, with the consent of the acquiring or
succeeding corporation, provide for the consideration to be received upon the
exercise of Options to consist solely of common stock of the acquiring or
succeeding corporation (or an affiliate thereof) equivalent in fair market value
to the per share consideration received by holders of outstanding shares of
Common Stock as a result of the Reorganization Event.

     Notwithstanding the foregoing, if the acquiring or succeeding corporation
(or an affiliate thereof) does not agree to assume, or substitute for, such
Options, then the Board shall, upon written notice to the Participants, provide
that all then unexercised Options will become exercisable in full as of a
specified time prior to the Reorganization Event and will terminate immediately
prior to the consummation of such Reorganization Event, except to the extent
exercised by the Participants before the consummation of such Reorganization
Event; provided, however, that in the event of a Reorganization Event under the
terms of which holders of Common Stock will receive upon consummation thereof a
cash payment for each share of Common Stock surrendered pursuant to such
Reorganization Event (the "Acquisition Price"), then the Board may instead
provide that all outstanding Options shall terminate upon consummation of such
Reorganization Event and that each Participant shall receive, in exchange
therefor, a cash payment equal to the amount (if any) by which (A) the
Acquisition Price multiplied by the number of shares of Common Stock subject to
such outstanding Options (whether or not then exercisable), exceeds (B) the
aggregate exercise price of such Options. To the extent all or any portion of an
Option becomes exercisable solely as a result of the first sentence of this
paragraph, upon exercise of such Option the Participant shall receive shares
subject to a right of repurchase by the Company or its successor at the Option
exercise price. Such repurchase right (1) shall lapse at the same rate as the
Option would have become exercisable under its terms and (2) shall not apply to
any shares subject to the Option that were exercisable under its terms without
regard to the first sentence of this paragraph.

          (3) Consequences of a Reorganization Event on Restricted Stock Awards.
Upon the occurrence of a Reorganization Event, the repurchase and other rights
of the Company under each outstanding Restricted Stock Award shall inure to the
benefit of the Company's successor and shall apply to the cash, securities or
other property which the Common Stock was converted into or exchanged for
pursuant to such Reorganization Event in the same manner and to the same extent
as they applied to the Common Stock subject to such Restricted Stock Award.

8.   General Provisions Applicable to Awards

     (a) Transferability of Awards. Except as the Board may otherwise determine
or provide in an Award, Awards shall not be sold, assigned, transferred, pledged
or otherwise encumbered by the person to whom they are granted, either
voluntarily or by operation of law, except by will or the laws of descent and
distribution, and, during the life of the Participant, shall be exercisable only
by the Participant. References to a Participant, to the extent relevant in the
context, shall include references to authorized transferees.

                                       -5-

<PAGE>

     (b) Documentation. Each Award shall be evidenced in such form (written,
electronic or otherwise) as the Board shall determine. Each Award may contain
terms and conditions in addition to those set forth in the Plan.

     (c) Board Discretion. Except as otherwise provided by the Plan, each Award
may be made alone or in addition or in relation to any other Award. The terms of
each Award need not be identical, and the Board need not treat Participants
uniformly.

     (d) Termination of Status. The Board shall determine the effect on an Award
of the disability, death, retirement, authorized leave of absence or other
change in the employment or other status of a Participant and the extent to
which, and the period during which, the Participant, the Participant's legal
representative, conservator, guardian or Designated Beneficiary may exercise
rights under the Award.

     (e) Withholding. Each Participant shall pay to the Company, or make
provision satisfactory to the Board for payment of, any taxes required by law to
be withheld in connection with Awards to such Participant no later than the date
of the event creating the tax liability. Except as the Board may otherwise
provide in an Award, when the Common Stock is registered under the Exchange Act,
Participants may satisfy such tax obligations in whole or in part by delivery of
shares of Common Stock, including shares retained from the Award creating the
tax obligation, valued at their Fair Market Value; provided, however, that the
total tax withholding where stock is being used to satisfy such tax obligations
cannot exceed the Company's minimum statutory withholding obligations (based on
minimum statutory withholding rates for federal and state tax purposes,
including payroll taxes, that are applicable to such supplemental taxable
income). The Company may, to the extent permitted by law, deduct any such tax
obligations from any payment of any kind otherwise due to a Participant.

     (f) Amendment of Award. The Board may amend, modify or terminate any
outstanding Award, including but not limited to, substituting therefor another
Award of the same or a different type, changing the date of exercise or
realization, and converting an Incentive Stock Option to a Nonstatutory Stock
Option, provided that the Participant's consent to such action shall be required
unless the Board determines that the action, taking into account any related
action, would not materially and adversely affect the Participant.

     (g) Conditions on Delivery of Stock. The Company will not be obligated to
deliver any shares of Common Stock pursuant to the Plan or to remove
restrictions from shares previously delivered under the Plan until (i) all
conditions of the Award have been met or removed to the satisfaction of the
Company, (ii) in the opinion of the Company's counsel, all other legal matters
in connection with the issuance and delivery of such shares have been satisfied,
including any applicable securities laws and any applicable stock exchange or
stock market rules and regulations, and (iii) the Participant has executed and
delivered to the Company such representations or agreements as the Company may
consider appropriate to satisfy the requirements of any applicable laws, rules
or regulations.

     (h) Acceleration. The Board may at any time provide that any Award shall
become immediately exercisable in full or in part, free of some or all
restrictions or conditions, or otherwise realizable in full or in part, as the
case may be.

                                       -6-

9.   Miscellaneous

     (a) No Right To Employment or Other Status. No person shall have any claim
or right to be granted an Award, and the grant of an Award shall not be
construed as giving a Participant the right to continued employment or any other
relationship with the Company. The Company expressly reserves the right at any
time to dismiss or otherwise terminate its relationship with a Participant free
from any liability or claim under the Plan, except as expressly provided in the
applicable Award.

     (b) No Rights As Stockholder. Subject to the provisions of the applicable
Award, no Participant or Designated Beneficiary shall have any rights as a
stockholder with respect to any shares of Common Stock to be distributed with
respect to an Award until becoming the record holder of such shares.
Notwithstanding the foregoing, in the event the Company effects a split of the
Common Stock by means of a stock dividend and the exercise price of and the
number of shares subject to such Option are adjusted as of the date of the
distribution of the dividend (rather than as of the record date for such
dividend), then an optionee who exercises an Option between the record date and
the distribution date for such stock dividend shall be entitled to receive, on
the distribution date, the stock dividend with respect to the shares of Common
Stock acquired upon such Option exercise, notwithstanding the fact that such
shares were not outstanding as of the close of business on the record date for
such stock dividend.

     (c) Effective Date and Term of Plan. The Plan shall become effective on the
date on which it is adopted by the Board, but no Award granted to a Participant
that is intended to comply with Section 162(m) shall become exercisable, vested
or realizable, as applicable to such Award, unless and until the Plan has been
approved by the Company's stockholders to the extent stockholder approval is
required by Section 162(m) in the manner required under Section 162(m)
(including the vote required under Section 162(m)). No Awards shall be granted
under the Plan after the completion of ten years from the earlier of (i) the
date on which the Plan was adopted by the Board or (ii) the date the Plan was
approved by the Company's stockholders, but Awards previously granted may extend
beyond that date.

     (d) Amendment of Plan. The Board may amend, suspend or terminate the Plan
or any portion thereof at any time, provided that to the extent required by
Section 162(m), no Award granted to a Participant that is intended to comply
with Section 162(m) after the date of such amendment shall become exercisable,
realizable or vested, as applicable to such Award, unless and until such
amendment shall have been approved by the Company's stockholders if required by
Section 162(m) (including the vote required under Section 162(m)).

     (e) Governing Law. The provisions of the Plan and all Awards made hereunder
shall be governed by and interpreted in accordance with the laws of the State of
Delaware, without regard to any applicable conflicts of law.
