                                 VOXWARE, INC.
                      1994 STOCK OPTION PLAN, as amended

1.   PURPOSE. The purpose of the Voxware, Inc. 1994 Stock Option Plan (the
     --------
     "Plan") is to enable Voxware, Inc. (the "Company") and its stockholders to
     secure the benefits of common stock ownership by key personnel of the
     Company and its subsidiaries. The Board of Directors of the Company (the
     "Board") believes that the granting of options under the Plan will foster
     the Company's ability to attract, retain and motivate those individuals who
     will be largely responsible for the profitability and long-term future
     growth of the Company.

2.   STOCK SUBJECT TO THE PLAN. The Company may issue and sell a total of
     --------------------------
     4,000,000 shares of its common stock (the "Common Stock") pursuant to the
     Plan. Such shares may be either authorized and unissued or held by the
     Company in its treasury. New options may be granted under the Plan with
     respect to shares of Common Stock which are covered by the unexercised
     portion of an option which has terminated or expired by its terms, by
     cancellation or otherwise.

3.   ADMINISTRATION. The Plan will be administered by the Board or a
     ---------------
     committee (the "Committee") consisting of at least two directors appointed
     by and serving at the pleasure of the Board (or, if there is only one
     director, the Committee shall consist of the sole director). Subject to the
     provisions of the Plan, the Board or the Committee, as the case may be,
     acting in its sole and absolute discretion, will have full power and
     authority to grant options under the Plan, to interpret the provisions of
     the Plan, to fix and interpret the provisions of option agreements made
     under the Plan, to supervise the administration of the Plan, and to take
     such other action as may be necessary or desirable in order to carry out
     the provisions of the Plan. A majority of the members of the Committee will
     constitute a quorum. The Committee may act by the vote of a majority of its
     members present at a meeting at which there is a quorum or by unanimous
     written consent. The decision of the Board or the Committee, as the case
     may be, as to any disputed question, including questions of construction,
     interpretation and administration, will be final and conclusive on all
     persons. The Committee will keep a record of its proceedings and acts and
     will keep or cause to be kept such books and records as may be necessary in
     connection with the proper administration of the Plan.

4.   ELIGIBILITY. Options may be granted under the Plan to present or
     ------------
     future key employees of the Company or a subsidiary of the Company (a
     "Subsidiary") within the meaning of Section 424(f) of the Internal Revenue
     Code of 1986 (the "Code"), and to directors of and consultants to the
     Company or a Subsidiary who are not employees. Subject to the provisions of
     the Plan, the Board or the Committee, as the case may be, may from time to
     time select the persons to whom options will be granted, and will fix the
     number of shares covered by each such option and establish the terms and
     conditions thereof (including, without limitation, the exercise price,
     restrictions on exercisability of the option and/or on the disposition of
     the
<PAGE>

     shares of Common Stock issued upon exercise thereof, and whether or not the
     option is to be treated as an incentive stock option within the meaning of
     Section 422 of the Code (an "Incentive Stock Option").

5.   TERMS AND CONDITIONS OF OPTIONS.  Each option granted under the Plan  will
     --------------------------------
     be evidenced by a written agreement in a form approved by the Board or the
     Committee. Each such option will be subject to the terms and conditions set
     forth in this paragraph and such additional terms and conditions not
     inconsistent with the Plan as the Board or the Committee deems appropriate.

     A.   OPTION EXERCISE PRICE.  In the case of an option which is not treated
          ----------------------
          as an Incentive Stock Option, the exercise price per share may not be
          less than the par value of a share of Common Stock on the date the
          option is granted; and, in the case of an Incentive Stock Option, the
          exercise price per share may not be less than 100% of the fair market
          value of a share of Common Stock on the date the option is granted
          (110% in the case of an optionee who, at the time the option is
          granted, owns stock possessing more than 10% of the total combined
          voting power of all classes of stock of the Company or a Subsidiary (a
          "ten percent shareholder")). For purposes hereof, the fair market
          value of a share, of Common Stock on any date will be equal to the
          closing sale price per share as published by a national securities
          exchange on which shares of the Common Stock are traded on such date
          or, if there is no sale of Common Stock on such date, the average of
          the bid and asked prices on such exchange at the closing of trading on
          such date or, if shares of the Common Stock are not listed on a
          national securities exchange on such date, the closing price or, if
          none, the average of the bid and asked prices in the over the counter
          market at the close of trading on such date, or if the Common Stock is
          not traded on a national securities exchange or the over the counter
          market, the fair market value of a share of the Common Stock on such
          date as determined in good faith by the Board or the Committee.

     B.   OPTION PERIOD.  The period during which an option may be exercised
          --------------
          will  be fixed by the Board or the Committee and will not exceed ten
          years from the date the option is granted (five years in the case of
          an Incentive Stock Option granted to a "ten percent shareholder").

     C.   EXERCISE OF OPTIONS.  Except as otherwise determined by the Board or
          --------------------
          the Committee, no option will become exercisable unless the person to
          whom the option was granted remains in the continuous employ or
          service of the Company or a Subsidiary for at least six months from
          the date the option is granted.  The Board or the Committee may
          determine and set forth in the option agreement any vesting or other
          restrictions on the exercisability of an option, subject to earlier
          termination of the option as provided herein.  All or part of the
          exercisable portion of an option may

                                       2
<PAGE>

          be exercised at any time during the option period. An option may be
          exercised by transmitting to the Company (a) a written notice
          specifying the number of shares to be purchased, and (b) payment of
          the exercise price (or, if applicable, delivery of a secured
          obligation therefor), together with the amount, if any, deemed
          necessary by the Board or the Committee to enable the Company to
          satisfy its income tax withholding obligations with respect to such
          exercise (unless other arrangements acceptable to the Company are made
          with respect to the satisfaction of such withholding obligations).

     D.   PAYMENT OF EXERCISE PRICE.  The purchase price of shares of Common
          --------------------------
          Stock acquired pursuant to the exercise of an option granted under the
          Plan may be paid in cash and/or such other form of payment as may be
          permitted under the option agreement, including, without limitation,
          previously-owned shares of Common Stock.  The Board or the Committee
          may permit the payment of all or a portion of the purchase price in
          installments (together with interest) over a period of not more than
          five years.

     E.   RIGHTS AS A STOCKHOLDER.  No shares of Common Stock will be issued in
          ------------------------
          respect of the exercise of an option granted under the Plan until full
          payment therefor has been made (and/or provided for where all or a
          portion of the purchase price is being paid in installments).  The
          holder of an option will have no rights as a stockholder with respect
          to any shares covered by an option until the date a stock certificate
          for such shares is issued to him or her. Except as otherwise provided
          herein, no adjustments shall be made for dividends or distributions of
          other rights for which the record date is prior to the date such stock
          certificate is issued.

     F.   NONTRANSFERABILITY OF OPTIONS.  No option shall be assignable or
          ------------------------------
          transferrable except upon the optionee's death to a beneficiary
          designated by the optionee in accordance with procedures established
          by the Committee or, if no designated beneficiary shall survive the
          optionee, pursuant to the optionee's will or by the laws of descent
          and distribution.  During an optionee's lifetime, options may be
          exercised only by the optionee or the optionee's guardian or legal
          representative.

     G.   TERMINATION OF EMPLOYMENT OR OTHER SERVICE.  Unless otherwise
          -------------------------------------------
          determined by the Board or the Committee, if an optionee ceases to be
          employed by or to perform services for the Company and any Subsidiary
          for any reason other than death or disability (defined below), then
          each outstanding option granted to him or her under the Plan will
          terminate on the date three months after the date of such termination
          of employment or service, provided, however, that, if the optionee's
          employment or service is terminated by the Company for cause (defined
          below), then the option will terminate upon the date of such
          termination of employment or service.  If an optionee's employment or
          service is terminated by reason of the optionee's death

                                       3
<PAGE>

          or disability (or if the optionee's employment or service is
          terminated by reason of his or her disability and the optionee dies
          within one year after such termination of employment or service), then
          each outstanding option granted to the optionee under the Plan will
          terminate on the date one year after the date of such termination of
          employment or service (or one year after the later death of a disabled
          optionee) or, if earlier, the date specified in the option agreement.
          For purposes hereof, unless otherwise agreed by the Board or the
          Committee in an option agreement, the term "disability" means the
          inability of an optionee to perform the customary duties of his or her
          employment or other service for the Company or a Subsidiary by reason
          of a physical or mental incapacity which is expected to result in
          death or be of indefinite duration; and, unless otherwise agreed by
          the Board or the Committee in an option agreement, the term "cause"
          means (1) failure or refusal by optionee to perform the duties of his
          or her employment with the Company, (2) commission by the optionee of
          a crime involving moral turpitude, or (3) the optionee's dishonesty or
          willful engagement in conduct which is injurious to the business or
          reputation of the Company, all as determined by the Board in its sole
          discretion.

     H.   OTHER PROVISIONS.  The Board or the Committee may impose such other
          -----------------
          conditions with respect to the exercise of options, including, without
          limitation, any conditions relating to the application of federal or
          state securities laws, as it may deem necessary or advisable.

6.   CHANGE IN CONTROL; CAPITAL CHANGES.
     -----------------------------------

     a.   Unless otherwise determined by the Board in an option agreement with
          respect to any particular option, if any event constituting a "Change
          in Control of the Company" shall occur, all options granted under the
          Plan which are outstanding at the time a Change of Control of the
          Company shall occur shall immediately become exercisable.  Unless
          otherwise determined by the Board in an  option agreement with respect
          to any particular option, a "Change in Control of the Company" shall
          be deemed to occur if (i) there shall be consummated (x) any
          consolidation or merger of the Company in which the Company is not the
          continuing or surviving corporation or pursuant to which shares of the
          Company's Common Stock would be converted into cash, securities or
          other property, other than a merger of the Company in which the
          holders of the Company's Common Stock immediately prior to the merger
          have the same proportionate ownership of common stock of the surviving
          corporation immediately after the merger, or (y) any sale, lease,
          exchange or other transfer (in one transaction or a series of related
          transactions) of all, or substantially all, of the assets of the
          Company, or (ii) the stockholders of the Company shall approve any
          plan or proposal for liquidation or dissolution of the Company, or
          (iii) any person (as such term is used in Section 13(d) and 14(d)(2)
          of the Securities Exchange Act of 1934, as amended (the "Exchange
          Act")), shall become the beneficial owner (within the meaning of Rule

                                       4
<PAGE>

          13d-3 under the Exchange Act) of more than 50% of the Company's
          outstanding Common Stock other than pursuant to a plan or arrangement
          entered into by such person and the Company, or (iv) during any period
          of two consecutive years, individuals who at the beginning of such
          period constitute the entire Board of Directors shall cease for any
          reason to constitute a majority thereof unless the election, or the
          nomination for election by the Company's stockholders, of each new
          director was approved by a vote of at least two-thirds of the
          directors then still in office who were directors at the beginning of
          the period; provided, however, that stock ownership changes and
          changes in the composition of the Board will not constitute a "change
          in control" for purposes hereunder if and to the extent any such
          change occurs as a result of or in connection with a public offering
          of the Company's stock.

     b.   In the event of any stock split, stock dividend or similar transaction
          which increases or decreases the number of outstanding shares of
          Common Stock, appropriate adjustment shall be made by  the Board to
          the number and option exercise price per share of Common Stock which
          may be purchased under any outstanding options. In the case of a
          merger, consolidation or similar transaction which results in a
          replacement of the Company's Common Stock with stock of another
          corporation but does not constitute Change in Control of the Company,
          the Company will make a reasonable effort, but shall not be required,
          to replace any outstanding options granted under the Plan with
          comparable options to purchase the stock of such other corporation, or
          will, unless otherwise determined by the Committee or the Board in an
          option agreement with respect to any particular option, the Company
          will provide for immediate maturity of all outstanding options, with
          all options not being exercised within the time period specified by
          the Board being terminated.

     c.   In the event of any adjustment in the number of shares covered by any
          option pursuant to the provisions hereof, any fractional shares
          resulting from such adjustment will be disregarded and each such
          option will cover only the number of full shares resulting from the
          adjustment.

     d.   All adjustments under this paragraph 6 shall be made by the Board, and
          its determination as to what adjustments shall be made, and the extent
          thereof, shall be final, binding and conclusive.

7.   AMENDMENT AND TERMINATION OF THE PLAN.  The Board may amend or terminate
     --------------------------------------
     the Plan. Except as otherwise provided in the Plan with respect to equity
     changes, any amendment which would increase the aggregate number of shares
     of Common Stock as to which options may be granted under the Plan, change
     the minimum option price for options, materially increase the benefits
     under the Plan, or modify the class of persons eligible to receive options
     under the Plan shall be subject to the approval of the Company's

                                       5
<PAGE>

     stockholders. No amendment or termination may affect adversely any
     outstanding option without the written consent of the optionee.

8.   NO RIGHTS CONFERRED.  Nothing contained herein will be deemed to give any
     --------------------
     individual any right to receive an option under the Plan or to be retained
     in the employ or service of the Company or any Subsidiary.

9.   GOVERNING LAW.  The Plan and each option agreement shall be governed by the
     --------------
     laws of the State of Delaware.

10.  DECISIONS AND DETERMINATIONS OF COMMITTEE TO BE FINAL.  Except to the
     ------------------------------------------------------
     extent rights or powers under this Plan are reserved specifically to the
     discretion of the Board, all decisions and determinations of the Committee
     are final and binding.

11.  TERM OF THE PLAN.  The Plan shall be effective as of the date on which it
     -----------------
     is adopted by the Board, subject to the approval of the stockholders of the
     Company within one year from the date of adoption by the Board. The Plan
     will terminate on the date ten years after the date of adoption by the
     Board, unless sooner terminated by the Board. The rights of optionees under
     options outstanding at the time of the termination of the Plan shall not be
     affected solely by reason of the termination and shall continue in
     accordance with the terms of the option (as then in effect or thereafter
     amended).

prior to the Closing Date, including, but not limited to, negligence, product
liability, whether based on contract or tort, or warranty claims regarding such
products, goods or services arising out of transactions, accidents or events on,
prior to, or after the Closing Date, and regardless of any claim was filed or
made known to the Seller or Buyer prior to the Closing Date ("Product Claims").

     (c)  Additional Liabilities. Notwithstanding the provisions of Subparagraph
2(a) to the contrary, and as an express exception thereto, Buyer shall assume,
perform and discharge Seller's liability, existing as of the Closing Date, with
respect to all duties and obligations of Seller with respect to the distribution
and sales agreements listed in Exhibit 1.(e), the assumption of which Buyer
expressly and separately acknowledges to Seller on the Closing Date ("Sales
Agreement Liabilities").

<PAGE>

     (b)  If Seller's Inventories, determined in accordance with Section 5(h),
are less than $100,000, then the difference shall be subtracted from the Price.
If Seller's Receivables exceed $130,000, the excess shall be subtracted from the
Price. The purchase price to be paid by Buyer shall be reduced by the aggregate
dollar amount of all Receivables that are not collected by Buyer within 60 days
following the Closing Date ("Uncollected Receivables"). Buyer shall use its best
efforts (which shall not include an obligation to commence collection
litigation) to collect the Receivables. Payments shall be applied to the oldest
invoice first, unless the customer otherwise indicates. All Uncollected
Receivables shall be reassigned to Seller and their value shall be deducted from
any future purchase price payments owed to Seller by Buyer; provided if no
future purchase price payments are owed to Seller by Buyer, then Seller shall
pay Buyer the amount of Uncollected Receivables within 10 business days
("Receivables Payment") (plus interest at eight percent (8%) if the Receivables
Payment is not paid timely).

     (c)  An amount equal to Fifteen Thousand Dollars ($15,000) of the Remaining
Cash Payment shall be assigned to a Covenant Not To Compete from Seller and
Salerno pursuant to Paragraph 23.

     (d)  The purchase price to be paid by Buyer shall be allocated in the
manner required by Section 1060 of the Internal Revenue Code of 1986, as amended

Certificate of Allocation substantially in the form of attached Exhibit 3.(d)
                                                                -------------
This allocation shall be conclusive and binding on the Buyer and Seller for all
purposes, including the reporting and disclosure requirements of the Code.

completion of the transaction shall be as of the close of business on the 31st

shall be deemed to be independently material and relied upon by Buyer,
regardless of any investigation made by, or information known to, Buyer:

     (a)  Organization and Qualification. Seller is validly existing and in good
standing under the laws of the State of Massachusetts. No failure on the part of

lease or similar agreement all of the Purchased Assets and to carry on the
Business as it is now being conducted.

     (b)  No Violation. Except as disclosed in Exhibit 5.(b), the execution and
                                               -------------
delivery of this Agreement by Seller and the consummation of the transactions
contemplated by it will not violate any provision of law, order, or regulation
of any governmental authority, the corporate charter or by-laws of Seller or
constitute a default under any judgment, order or decree of any court of
governmental agency or instrumentality, or conflict or constitute a breach or a
default under any agreement to which the Seller is a party or by which it is
bound.

     (c)  Financial Information. Seller has provided in Exhibit 5.(c) its (i)
                                                        -------------

records of Seller.

          (2)  Fairly present and are true, complete and correct statements of
Seller's financial position, the results of its operation, stockholder's equity
and cash flows of Seller as of and for the periods specified in the Financial
Statements.

          (3)  Have been prepared in accordance with generally accepted
accounting principles ("GAAP") consistently applied.

          (4)  Do not include or omit to state any fact that renders them
misleading.

          (5)  Make full and adequate disclosure of all Seller's obligations and

<PAGE>

          (6)  Do not contain any items of special or non-recurring income or
expenses except as expressly stated in the Financial Statements.

Seller, as evidenced in Exhibit 5.(d).ii (collectively, "Contracts"). All
                        ----------------

environmental, health and safety rules and other rules and regulations. All of
the Purchased Assets utilized in the Business, including all their components
and parts, are ready for operation, and, taking into account their ages, are in
normal operating condition and good order and repair. There are no conditions or

Assets, which would prevent the continued normal operation of the Purchased
Assets or would otherwise materially and adversely affect their operation or use
by Buyer after the Closing as currently used by Seller.

proceeds to which the Indemnified Party is entitled and (iii) any warranty
reimbursements (collectively, "Damages").

     (e)  Assertion and Defense of Indemnification Claims.

          (1)  Assertion of Claim. Buyer or Seller and Salerno under Paragraphs
9.(b) and (d), respectively ("Indemnified Party"), shall give notice to the
other ("Indemnifying Party") as soon as reasonably possible after the
Indemnified Party has actual knowledge of any claim to which the Indemnifying
Party has an obligation to indemnify, including the amount, if known, and shall
promptly supply any other information in possession of the Indemnified Party
supporting the claim. The omission by the Indemnified Party to give Notice as
soon as reasonably possible will not relieve the Indemnifying Party of its
indemnification obligations, unless the failure to give notice to the
Indemnifying Party materially prejudices the Indemnifying Party or notice is
given after the end of the survival period of the applicable representation of
warranty or other basis of the claim. All indemnification claims must be
asserted by giving notice within the survival period of the applicable
representation or warranty or other basis for the claim. Buyer shall have the
right to set off any Damages it may incur against the amount it owes Seller.
This right of set off shall be in addition to any other rights or remedies Buyer
may have against Seller.

          (2)  Defense of Undisputed Claim. The Indemnified Party will permit
the Indemnifying Party (at its expense) to assume the defense of any third party
claim in any litigation. The Indemnifying Party may settle or compromise any
third party claim or litigation only with the consent of the Indemnified Party,
which consent shall not be unreasonably withheld. The Indemnified Party shall
have the right at all times to participate in the defense, settlement,
negotiations or litigation relating to any third party claim or demand at its
own expense. If the Indemnifying Party does not assume the defense of any matter
which it has an obligation to indemnify, then the Indemnified Party shall have
the right to defend any such third party claim or demand, and will be entitled
to settle any such claim or demand in its discretion, all at the expense of the
Indemnifying Party. In any event, the Indemnified Party will cooperate in the
defense of any such action at the expense of the Indemnifying Party and the
pertinent records of each party shall be available to the other with respect to
the defense.

          (3)  Defense of Disputed Claim. Should an Indemnifying Party provide
Notice to the Indemnified Party regarding a claim or action by a third party for
which the Indemnifying Party denies liability, the Indemnified Party shall give
the Indemnifying Party a reasonable opportunity: (1) to conduct any proceedings
or negotiations in connection therewith; (2) to take all other required steps or
proceedings to settle or defend any third party action; or (3) to employ counsel
to contest any third party claim or action in the name of the Indemnified Party
or otherwise. If the Indemnifying Party desires to assume the defense of the
third party claim or action, it shall promptly give Notice to the Indemnified
Party. The Indemnifying Party and the Indemnified Party may participate in the
defense at their own expense.

     (f)  Limitation on Recovery. Anything in this Paragraph 9 to the contrary
notwithstanding, there shall be no recovery (I) under Paragraphs 9.(b)(1) or (6)
until the total claims for indemnification under those provisions exceed $5,000;
and (II) under Paragraph 9.(b) after the total recovery on all claims for
indemnification under Paragraph 9.(b) have exceeded the Price.

     (g)  Attempt at Resolving Disputes. Seller and Buyer agree to use
reasonable efforts to settle any dispute during the 30 days immediately
following a claim for indemnity being made; provided, Buyer shall have no duty
to seek resolution under this Paragraph 9.(g) of any breach, threatened breach
or dispute pursuant to Paragraphs 23 and 24.

     10.  Covenants.

     (a)  Salerno's and Seller's Covenants. Seller and Salerno covenant and

parties consent to jurisdiction and waive all claims of improper venue and forum
non-conviens.

          15.  Bulk Transfer. Buyer agrees to waive compliance with the
provisions of any applicable bulk sale or transfer of law in exchange for
Seller's covenant to indemnify and hold Buyer harmless from and against all
liabilities Buyer may incur arising from such non-compliance.

          16.  Integration. This Agreement and the Confidentiality Agreement,
dated on or about April 25, 2000 (between Buyer and The Walden Group, Inc.),
sets forth the entire agreement and understanding between the parties as to the
subject matter, and supersedes all prior discussions, representations,
amendments or understandings of every kind and nature between them.

          17.  Amendments. Any amendment, alteration, supplement, modification
or waiver shall be invalid unless it is set forth in writing, signed by the
party intending to be bound thereby.

          18.  Severability. If any provision of this Agreement becomes or is
declared by a court of competent jurisdiction to be illegal, unenforceable or
void, this Agreement shall continue in full force and effect without the
provision.

          19.  Assignability. This Agreement may be assigned by Buyer without
the prior written consent of Seller; provided, Buyer shall continue to be liable
for the performance of all obligations pursuant to the Agreement. This Agreement
may not be assigned by Seller or Salerno without the prior written consent of
Buyer.

          20.  Benefit. This Agreement shall be binding upon and inure to the
benefit of Buyer and Seller and their respective successors and permitted

to refer to the masculine, feminine, neuter, singular or plural as the identity
of the parties may require.

          23.  Covenant Not to Compete. Without prior written consent of Buyer,
Seller and Salerno each agree that, for a ten year period from and after the

agent, employee, director, representative, stockholder, partner, co-venturer,
independent contractor or otherwise, of any other corporation, non-profit
organization or any other entity, directly or indirectly, own, manage, operate,
or control in the ownership, management, operation, or control of or work for,
or permit the use of their names by, or be connected in any manner with any
business or activity in any country which is at the time competitive with any
product of the Business as defined in Recital A. Anything in the preceding
sentence to the contrary notwithstanding, Seller and Salerno shall be permitted
to manufacture and sell Fura-Zone Products with its present formula and
packaging without being in violation of this Paragraph 23. While the
restrictions set forth above are considered by the parties to be reasonable in
all circumstances, it is recognized that restrictions of the nature in question
may fail for technical reasons unforeseen and accordingly it is hereby agreed
and declared that if any of such restrictions shall be adjudged to be void as
going beyond what is reasonable in all the circumstances for the protection of
the interests of the Buyer but would be valid if part of the wording were
deleted or the periods reduced or the range of activities or area dealt with
reduced in scope, these restrictions shall be applied with such modifications as
may be necessary to make them valid and effective.

          As consideration for this agreement not to compete, Fifteen Thousand
Dollars ($15,000) as a part of the Remaining Cash Payment shall be deemed as
payment for this covenant not to compete to Seller and Salerno. No additional
consideration shall be paid by Buyer.

          24.  Confidential Information. It is agreed that the products,
information and technology relating to the Business and anticipated improvements
relating to them constitute trade secrets. Seller and Salerno agree that they
shall not individually or jointly disclose to any person any Confidential
Information regardless of nature, type or physical manifestation or any other
information concerning the business affairs of Buyer and the Business,
including, but not limited to, information related to the products identified in
Recital A and improvements made thereto, except as specifically consented to in
advance in writing by Buyer. This restriction shall include information imparted
or divulged to, gained or developed by, or otherwise discovered by Seller or
Salerno in executing this Agreement. Anything in this Agreement to the contrary
notwithstanding, Seller and Salerno shall not be bound by this Paragraph 24 to
the extent that the information they desire to divulge is or becomes publicly
known, other than through a breach of their obligations pursuant any agreement
with Buyer or as required by law.

          25.  Injunctive Relief. Seller and Salerno acknowledge that a breach
of any of the covenants, agreements or promises contained in Paragraphs 23 and
24 could result in irreparable injury to Buyer for which there might be no
adequate remedy at law, and that, in the event of such a breach or threatened
breach, Buyer shall be entitled to obtain a temporary restraining order,
preliminary injunction and permanent injunction restraining Seller and Salerno
from engaging in any of the activities prohibited by Paragraphs 23 and 24.

          26.  Exhibits. The parties agree that the Exhibits attached to this
Agreement shall be treated for all purposes as part of this Agreement.

          27.  Prevailing Party. The prevailing party in any litigation
involving this Agreement (other than those matters governed by Paragraph 9,
which, for the avoidance of doubt, contains its own provision for fees and
expenses) shall be entitled to recover, in addition to any other relief
obtained, the costs and expenses, including reasonable attorney's fees and
expenses, incurred by the prevailing party.

          28.  Construction of Agreement. The parties agree that this Agreement
has been jointly drafted and that neither party may assert an ambiguity in the
construction of this Agreement against another party because the other party
