                         REPRESENTATIONS OF THE COMPANY

         The Company represents and warrants to the Purchaser as of the date of
this Agreement and as of the date of the Closing as follows:

         2.1 Existence and Good Standing. The Company is a corporation duly
organized, validly existing and in good standing under the laws of the State of
California. The Company has the power to own or lease its properties and assets
and to carry on its business as now being conducted. The Company is duly
qualified to do business and is in good standing in California, which is the

                                       3
<PAGE>

only jurisdiction in which the character or location of the properties owned or
leased by the Company or the nature of the business conducted by the Company
makes such qualification necessary. However, the failure to be so qualified or
in good standing in any given jurisdiction will not be deemed to be a breach of
this Section 2.1 unless the failure of the Company to be in good standing in any
such jurisdiction individually or in all such jurisdictions collectively has or
is likely to have a material adverse effect on the Company or on the
transactions contemplated herein.

         2.2 Capital Stock. The Company has an authorized capitalization
consisting of 10,000,000 shares of stock, $.001 par value, of which 8,000,000
shares are Common Stock and 2,000,000 shares are Preferred Stock. There are
3,807,755 shares of Common Stock issued and outstanding and no shares of
Preferred Stock are either issued or outstanding. All such outstanding shares
have been duly authorized and validly issued and are fully paid and
nonassessable. Except as set forth as Schedule 2.2 attached hereto, there are no
outstanding options, warrants, rights, calls, commitments, conversion rights,
rights of exchange, plans or other agreements, commitments or arrangements of
any character providing for the purchase, subscription, issuance or sale of any
shares of the capital stock of the Company, other than the sale of the Company
Shares as contemplated by this Agreement.

         2.3 Financial Statements and No Material Changes. Annexed hereto as
Schedule 2.3 is the unaudited consolidated balance sheet of the Company (the
"Financial Statements") as of March 31, 2004 (the "Balance Sheet Date").

         The Financial Statements were carefully prepared from the books and
records of the Company, and although the Financial Statements are not audited
and do not contain the footnotes which would be required in audited financial
statements, present fairly the financial position, assets and liabilities of the
Company and the results of its operations, on a cash basis for the respective
periods indicated applying accounting principles on a consistent basis.

         The Company maintains accurate books and records reflecting its assets
and liabilities and maintains proper and adequate internal accounting controls
which provide assurance that (i) transactions are executed with management's
authorization; (ii) transactions are recorded as necessary to maintain
accountability for the Company's consolidated assets; (iii) access to the
Company's assets is permitted only in accordance with management's
authorization; (iv) the reporting of the Company's assets is compared with
existing assets at regular intervals; and (v) accounts, notes and other
receivables and inventory are recorded accurately, and proper and adequate
procedures are implemented to effect the collection thereof on a current and
timely basis.

         Since the Balance Sheet Date there has been (a) no material adverse
change in the assets or liabilities, or in the business or condition, financial
or otherwise, or in the results of operations or prospects, of the Company
whether as a result of any legislative or regulatory change, revocation of any
license or rights to do business, fire, explosion, accident, casualty, labor
trouble, flood, drought, riot, storm, condemnation or act of God or other public
force or otherwise and (b) no material adverse change in the assets or
liabilities, or in the business or condition, financial or otherwise, or in the

                                       4
<PAGE>

results of operations or prospects, of the Company and to the best knowledge,
information and belief of the Shareholders, no fact or condition exists or is
contemplated or threatened which might cause such a change in the future.

         2.4 Books and Records. The corporate materials supplied to the
Purchaser are true, correct and complete in all material respects.

         2.5 Title to Properties; Encumbrances.

                  intangible), including, without limitation, all of the
                  properties and assets reflected in the balance sheet included

                  days prior to the date of this Agreement, have been set forth
                  on Schedule 2.5 attached hereto; in each case subject to no
                  encumbrance, lien, charge or other restriction of any kind or
                  character, except for (i) liens reflected in the balance
                  sheet, included as part of the Financial Statements; (ii)
                  liens consisting of zoning or planning restrictions,
                  easements, permits and other restrictions or limitations on
                  the use of real property or irregularities in title thereto
                  which do not materially detract from the value of, or impair
                  the use of, such property by the Company in the operation of
                  its business; (iii) liens for current taxes, assessments or
                  governmental charges or levies on property not yet due and
                  delinquent; and (iv) liens described on Schedule 2.5 attached
                  hereto (liens of the type described in clause (i), (ii) and
                  (iii) above are hereinafter sometimes referred to as
                  "Permitted Liens").

         (b)      The rights, properties and other assets presently owned,
                  leased or licensed, by the Company reflected on the balance
                  sheet included in the Financial Statements or acquired since
                  the Balance Sheet Date include all rights, properties and
                  other assets necessary to permit the Company to conduct its
                  business in the same manner as its business has heretofore
                  been conducted. All such properties and assets owned or leased
                  by the Company are in satisfactory condition and repair, other
                  than ordinary wear and tear.

                  To the Company's knowledge, no structure or improvement on the
                  real property leased by the Company, whether now existing or
                  intended to be constructed pursuant to existing plans and
                  specifications, violates, or if completed would violate, any
                  applicable zoning or building regulations or ordinances or
                  similar federal, state or municipal law.

                  With respect to the real property and structures and
                  improvements, whether now existing, under construction or
                  intended to be constructed pursuant to existing plans and
                  specifications, the Company has all governmental permits,
                  approvals, consents or similar authorizations necessary to own
                  or lease, construct and operate its properties, each of which
                  are listed on Schedule 2.5(b). Such governmental permits,

                                       5
<PAGE>

                  approvals, consents or similar authorizations will remain in
                  effect or, if due to expire by its terms, the Shareholders
                  have no reason to believe that they will not be renewable in
                  accordance with their terms.

                  To the Company's knowledge, no violations of any easements or
                  restrictions relating to the real property exist.

                  To the Company's knowledge, no material structural defects in
                  any of the buildings or other improvements erected on the
                  leased real property exist.

         2.6 Leases. Schedule 2.6 attached hereto, contains an accurate and
complete list and description of the terms of all leases to which the Company is
a party (as lessee or lessor). Each lease set forth on Schedule 2.6 (or required
to be set forth on Schedule 2.6) is in full force and effect; all rents and
additional rents due to date on each such lease have been paid; in each case,
the lessee has been in peaceable possession since the commencement of the
original term of such lease and is not in default thereunder and no waiver,
indulgence or postponement of the lessee's obligations thereunder has been
granted by the lessor; and there exists no event of default or event,
occurrence, condition or act (including the consummation of the transactions
contemplated hereby) which, with the giving of notice, the lapse of time or the
happening of any further event or condition, would become a default under such
lease. The Company has not violated any of the terms or conditions under any
such lease in any material respect. The property leased by the Company is in a
state of good maintenance and repair and is adequate and suitable for the
purposes for which it is presently being used.

hereto, the Company is not bound by:

         (a)      any agreement, contract or commitment relating to the

                  indebtedness or obligation of any Person (other than the

         (g)      any agreement, contract or commitment not entered into in the

                  is not cancelable without penalty or premium within 30 days;
                  or

         (h)      any agreement, contract or commitment which might reasonably
                  be expected to have a potential adverse impact on the business
                  or operations of the Company; or

         (i)      any agreement, contract or commitment not reflected in the
                  Financial Statement under which the Company is obligated to
                  make cash payments of, or deliver products or render services

                  commitment which is material to the conduct of the business of
                  the Company.

         Each contract or agreement set forth on Schedule 2.7 (or not required
to be set forth on Schedule 2.7) is in full force and effect and, to the
Company's knowledge, there exists no default or event of default or event,
occurrence, condition or act (including the consummation of the transactions
contemplated hereby) which, with the giving of notice, the lapse of time or the
happening of any other event or condition, would become a default or event of
default thereunder. The Company has not violated any of the terms or conditions
of any contract or agreement set forth on Schedule 2.7 (or not required to be
set forth on Schedule 2.7) in any material respect, and, to the knowledge, of
the Shareholders, all of the covenants to be performed by any other party
thereto have been fully performed. Except as set forth on Schedule 2.7, the
consummation of the transactions contemplated hereby does not constitute an
event of default (or an event, which with notice or the lapse of time or both
would constitute a default) under any such contract or agreement.

         2.8 Restrictive Documents. (a) Except as set forth on Schedule 2.8

law, rule, ordinance, regulation, order, judgment or decree, or any other
restriction of any kind or character, which could materially adversely affect
the business practices, operations or condition of the Company or any of its

business after the date hereof or the Closing Date (as hereinafter defined) on

                                       7

substantially the same basis as heretofore operated or which would restrict the
ability of the Company to acquire any property or conduct business in any area.

         2.9 Litigation. Except as set forth on Schedule 2.9 attached hereto,
there is no action, suit, proceeding at law or in equity, arbitration or
administrative or other proceeding by or before (or to the knowledge of the
Shareholders any investigation by) any governmental or other instrumentality or
agency, pending, or, to the knowledge of the Shareholders, threatened, against
or affecting the Company, or any of its properties or rights, or any officer,
director or employee of the Company other than such items which are
insignificant and immaterial and which do not adversely affect (i) the right or
ability of the Company to carry on business as now conducted; (ii) the
condition, whether financial or otherwise, or properties of the Company; or
(iii) the consummation of the transactions contemplated hereby. To the knowledge
of the Company there is no valid basis for any such action, proceeding or

judgments, injunctions, awards or decrees of any court, governmental or
regulatory body or arbitration tribunal by which either the Company, or any
officer, director or employee of the Company, or the securities, assets,
properties or business of any of them is bound, other than any such items which

caused to be filed, within the times and within the manner prescribed by law,
all federal, state, local and foreign tax returns and tax reports which are

reports reflect accurately all known liability for taxes of the Company for the
periods covered thereby. Except as set forth on Schedule 1.12, all federal,
state, local and foreign income, profits, franchise, employment, sales, use,
occupancy, excise and other taxes and assessments, stock and transfer taxes
(including interest and penalties) payable by, or shown to be due from, the
Company and any member of the consolidated group of which the Company is a part,
have been fully paid and fully provided for in the books and financial
statements of the Company. To the knowledge of the Company, no examination of
any tax return of the Company or any member of a consolidated group of which the
Company is a part, is currently in progress. There are no outstanding agreements

                          COVENANTS OF THE SHAREHOLDERS

         7.1 Non-Competition; Non-Interference. In consideration of the purchase
of the Shares by Purchaser, each Shareholder individually agrees that from the
date of this Agreement until the earlier of (i) June 30, 2007 and (ii) exercise
of the option under the Technology Acquisition Agreement, such Shareholder will
not, whether for their own account or for the account of any other person,
directly or indirectly:

         (a)      engage or invest in, own, manage, operate, control or
                  participate in the ownership, management, operation or control
                  of, be employed by, associated or in any manner connected with
                  or render services or advice to, any business, the products or
                  services of which compete, in whole or in part, with the
                  products or activities of the Company in which the Company was
                  engaged at the time up to the Closing Date;

         (b)      solicit any potential customer or client to which the Company
                  has made a presentation, or with which the Company has been in
                  contact, not to hire the Company, or to hire another company
                  whether or not such Company Party had personal contact with
                  such person during or by reason of his or its association with
                  the Company; or

         (c)      solicit the business of any company, which is a customer or
                  client of the Company, or was its customer or client within
                  two years prior to the date of this Agreement;

                                       26
<PAGE>

         (d)      persuade or attempt to persuade any employee of the Company,
                  or any individual who was its employee during the two years
                  prior to the date of this Agreement, to leave the Company's
                  employ, or to become employed by or otherwise be engaged as an
                  independent consultant or otherwise for, any person other than
                  the Company; or

         (e)      disclose or use any confidential information of the Company or
                  any of their clients and customers. For purposes of this
                  section "confidential information" with respect to any entity
                  shall mean trade secrets concerning such entity's operations,
                  future plans, projected and historical sales, marketing,
                  costs, production, growth and distribution, any customer
                  lists, customer information or other information relating to
                  the products or services, whether patentable or not,
                  concerning the business of such entity as conducted prior to
                  the Closing Date.

         (f)      Notwithstanding the foregoing, the Shareholder's duties and
                  obligations under this Section 7.1 shall terminate if the
                  Shareholders exercise their right to reacquire the Company's
                  technology pursuant to the terms of the Technology Agreement.

         7.2 Construction. It is the desire and intent of the parties to this
Agreement that the provisions of Section 7.1 shall be enforced to the fullest
extent permissible under the laws and public policies applied in each
jurisdiction in which enforcement is sought. If any particular provisions or
portion of Section 7.1 shall be adjudicated to be invalid or unenforceable, for
any reason, including, without limitation, the geographic or business scope or
duration thereof, such provision shall be construed in such a way as to make it
valid and enforceable to the maximum extent possible. Any validity or
unenforceability of any provision of this Agreement shall attach only to such
provision and shall not effect or render invalid any other provision of this
Agreement or any other agreement or instrument.

         7.3 Enforcement. The parties recognize that the performance of the
obligations under Section 7 by each Shareholder is special, unique and
extraordinary in character, and that in the event of the breach by such
Shareholder of the terms and conditions of Section 7.1 to be performed, the
Company and/or the Purchaser would suffer irreparable harm for which there would
be no adequate remedy at law. Accordingly, each Shareholder agrees that in such
event, in addition to any other remedies which the Company and/or Purchaser may
have in law or equity for money damages or other relief, the Company and the
Purchaser shall be entitled to temporary and/or injunctive relief, without the
necessity of posting a bond therefor or of proving damages, to enforce the
provisions hereof.

                 CONDUCT OF BUSINESS; EXCLUSIVE DEALING; REVIEW

                                       27
<PAGE>

         8.1. Conduct of Business of the Company. During the period from the
date of this Agreement to the Closing Date, the Shareholders shall cause the
Company and each of its subsidiaries to conduct their respective operations only
according to their ordinary and usual course of business and to use their best
efforts to preserve intact their respective business organizations, keep
available the services of their officers and employees and maintain satisfactory
relationships with licensors, suppliers, distributors, clients and others having
business relationships with them. Notwithstanding the immediately preceding
sentence, prior to the Closing Date, except as may be first approved by the
Purchaser or as is otherwise permitted or required by this Agreement, the
Shareholders will cause (a) the Company's and each of its subsidiaries'
respective Certificate of Incorporation and By-Laws to be maintained in their
form on the date of this Agreement, (b) the compensation payable or to become
payable by the Company and each of its subsidiaries to any officer, employee or
agent on the Balance Sheet Date to be maintained at their levels on the date of
this Agreement, (c) the Company and each of its subsidiaries to refrain from
making any bonus, pension, retirement or insurance payment or arrangement to or
with any such persons except those that may have already been accrued, (d) the
Company and each of its subsidiaries to refrain from entering into any contract
or commitment except contracts in the ordinary course of business, (e) the
Company and each of its subsidiaries to refrain from making any change affecting
any bank, safe deposit or power of attorney arrangements of the Company or any
such subsidiary and (f) the Company and each of its subsidiaries to refrain from
taking any of the actions referred to in Section 2.17 hereof. The Shareholders
agree not to take any action, or omit to take any action, which would cause the
representations and warranties contained in Article I hereof to be untrue or
incorrect. During the period from the date of this Agreement to the Closing
Date, the Shareholders shall cause the Company to confer on a regular and
frequent basis with one or more designated representatives of the Purchaser to
report material operational matters and to report the general status of ongoing
operations. The Shareholders shall cause the Company and each of its
subsidiaries to notify Purchaser of any unexpected emergency or other change in
the normal course of its business or in the operation of its properties and of
any governmental complaints, investigations or hearings (or communications
indicating that the same may be contemplated), adjudicatory proceedings, budget
meetings or submissions involving any material property of the Company and each
of its subsidiaries, and to keep Purchaser fully informed of such events and
permit its representatives prompt access to all materials prepared in connection
therewith.

         8.2. Exclusive Dealing. During the period from the date of this
Agreement to the earlier of (a) Closing Date or (b) termination of this
Agreement in accordance with Section 10.15 below, the Shareholders shall not,
and shall cause the Company to refrain from taking any action to, directly or
indirectly, encourage, initiate or engage in discussions or negotiations with,
or provide any information to, any Person, other than the Purchaser, concerning
any purchase of the shares, securities of the Company or any merger, sale of
assets or similar transaction involving the Company.

         8.3. Further Review. Shareholders and the Purchaser may, prior to the
Closing Date, through their representatives, review the properties, books and
records of the Company or Purchaser, respectively, and each of its subsidiaries

                                       28
<PAGE>

and its financial and legal condition as they deem necessary or advisable to
familiarize themselves with such properties and other matters; such review shall
not, however, affect the representations and warranties made by the other party
hereunder or the remedies of the reviewing party for breaches of those
representations and warranties. The Shareholders shall cause the Company and
each of its subsidiaries to, and Purchaser shall permit, after the date of
execution of this Agreement, full access to the premises and to all the books
and records of the Purchaser and Company, respectively, and their subsidiaries
and to cause the officers of the Purchaser and Company and each of their
subsidiaries to furnish the reviewing party and their representatives with such
financial and operating data and other information with respect to the business
and properties of the Purchaser or Company, as the case may be, and their
subsidiaries as the reviewing party shall from time to time reasonably request.
In the event of termination of this Agreement, the reviewing party shall keep
confidential any material information obtained from the Purchaser, the
Shareholders or the Company or any subsidiary concerning respective properties,
operations and business (unless readily ascertainable from public or published
information or trade sources) until the same ceases to be material (or becomes
so ascertainable) and, at the request of the reviewed party, shall return to the
reviewed party and its subsidiaries all copies of any schedules, statements,
documents or other written information obtained in connection therewith. The
reviewed party shall deliver or cause to be delivered such additional
instruments as the reviewing party may reasonably request for the purpose of
consummating the transactions contemplated by this Agreement.

                 SURVIVAL OF REPRESENTATIONS; INDEMNITY; SET-OFF

         9.1 Survival of Covenants and Agreements. The respective
representations, warranties, covenants and agreements of the Shareholders, the
Company and the Purchaser contained in this Agreement, or any Schedule attached
hereto or any agreement or document delivered pursuant to this Agreement shall
survive for a period of one year from the consummation of the transactions
contemplated hereby; provided, however, that the representations, warranties and
agreements made with regard to taxes and ERISA matters shall survive until the
applicable statutes of limitations have expired.

         9.2 Indemnification.

         (a)      The Shareholders agree to indemnify and hold the Purchaser and
                  their officers, directors, shareholders, employees, affiliates
                  and agents harmless from damages, losses, liabilities,
                  assessments, judgments, costs or expenses (including, without
                  limitation, penalties, interest and reasonable counsel fees
                  and expenses), (each a "Claim"), in excess of $25,000 in the
                  aggregate, as a result of or arising out of the material
                  breach of any representation or warranty made by the
                  Shareholders and the Company, or the failure of any material
                  representation or warranty made by the Shareholders and the
                  Company in this Agreement or in any Schedule attached hereto

                                       29
<PAGE>

                  or any document or agreement delivered hereunder to be true
                  and correct in all material respects as of the date of this
                  Agreement and as of the Closing Date.

         (b)      The Purchaser agrees to indemnify and hold the Shareholders
                  and each of their officers, directors, shareholders,
                  employees, affiliates and agents harmless from damages, losses
                  or expenses (including, without limitation, reasonable counsel
                  fees and expenses) in excess of $25,000, in the aggregate,
                  suffered or paid, directly or indirectly, as a result of or
                  arising out of the failure of any representation or warranty
                  made by the Purchaser in this Agreement to be true and correct
                  in all respects as of the date of this Agreement and as of the
                  Closing Date.

         9.3 Conditions of Indemnification.

         (a)      A party entitled to indemnification hereunder (the
                  "Indemnified Party") shall notify the party or parties liable
                  for such indemnification (the "Indemnified Party") in writing
                  of any Claim or potential liability for Taxes ("Tax Claim")
                  which the Indemnified Party has determined has given or could
                  give rise to a right of indemnification under this Agreement.
                  Such notice shall be given within a reasonable (taking into
                  account the nature of the Claim or Tax Claim) period of time
                  after the Indemnified Party has actual knowledge thereof. The
                  Indemnifying Party shall satisfy its obligations under this
                  Article 8 within forty days after receipt of subsequent
                  written notice from the Indemnified Party if an amount is
                  specified therein, or promptly following receipt of subsequent
                  written notice or notices specifying the amount of such Claim
                  or Tax Claim additions thereto; provided, however, that for so
                  long as the Indemnifying Party is in good faith defending a
                  Claim or Tax Claim pursuant to Section 9.3(b) hereof, its
                  obligation to indemnify the Indemnified Party with respect
                  thereto shall be suspended (other than with respect to any
                  costs, expenses or other liabilities incurred by the
                  Indemnified Party prior to the assumption of the defense by
                  the Indemnifying Party). Failure to provide a notice of Claim
                  or Tax Claim within the time period referred to above shall
                  not constitute a defense to a Claim or Tax Claim or release
                  the Indemnifying Party from any obligation hereunder to the
                  extent that such failure does not prejudice the position of
                  the Indemnifying Party.

         (b)      If the facts giving rise to any such indemnification involve
                  any actual, threatened or possible Claim or demand or Tax
                  Claim by any person not a party to this Agreement against the
                  Indemnified Party, the Indemnifying Party shall be entitled to
                  contest or defend such Claim or demand Tax Claim at its
                  expense and through counsel of its own choosing, which counsel
                  shall be reasonably acceptable to the Indemnified Party, such
                  right to contest or defend shall only apply if the

                                       30
<PAGE>

                  Indemnifying Party gave written notice of its intention to
                  assume the contest and defense of such Claim or demand Tax
                  Claim to the Indemnified Party as soon as practicable, but in
                  no event more than thirty days after receipt of the notice of
                  Claims or Tax Claim, and provided the Indemnified Party with
                  appropriate assurances as to the creditworthiness of the
                  Indemnifying Party, and that the Indemnifying Party will be in
                  a position to pay all fees, expenses and judgments that might
                  arise out of such Claim or demand Tax Claim. The Indemnified
                  Party shall have the obligation to cooperate in the defense of
                  any such Claim or demand Tax Claim and the right, at its own
                  expense, to participate in the defense of any Claim or Tax
                  Claim. So long as the Indemnifying Party is defending in good
                  faith any such Claim or demand Tax Claim asserted by a third
                  party against the Indemnified Party, the Indemnified Party
                  shall not settle or compromise such Claim or demand Tax Claim.
                  The Indemnifying Party shall have the right to settle or
                  compromise any such Claim or demand Tax Claim without the
                  consent of the Indemnified Party at any time utilizing its own
                  funds to do so if in connection with such settlement or
                  compromise the Indemnified Party is fully released by the
                  third party and is paid in full any indemnification amounts
                  due hereunder. The Indemnified Party shall make available to
                  the Indemnifying Party or its agents all records and other
                  materials in the Indemnified Party's possession reasonably
                  required by it for its use in contesting any third party Claim
                  or demand Tax Claim and shall otherwise cooperate, at the
                  expense of the Indemnifying Party, in the defense thereof in
                  such manner as the Indemnifying Party may reasonably request.
                  Whether or not the Indemnifying Party elects to defend such
                  Claim or demand Tax Claim, the Indemnified Party shall have no
                  obligation to do so.

         9.4 Limitations on Indemnification for Breaches of Representations and
Warranties. Notwithstanding anything contained in this Agreement to the
contrary, (a) the individual liability of the Shareholders under Section 9.2 for
any liability arising as a result of the failure of Shareholders' or Company's
representations and warranties to be true and correct or arising for any other
reason under Section 9.2(a), shall not exceed the number of Escrowed Shares
multiplied by the $.95 (the "Closing Value") and the cancellation of the
Escrowed Shares shall be the sole remedy of Purchaser in respect of such
indemnification; and (b) the aggregate liability of Purchaser and its affiliates
under Section 9.2(b) for any liability arising as a result of the failure of
Purchaser's representations and warranties to be true and correct, shall not
exceed the number of Contingent Shares multiplied by the Closing Value and the
release of Contingent Shares form escrow to Shareholders shall be the sole
remedy in respect of such indemnification.

         9.5 Payment of Indemnification Liabilities.

         (a)      At the sole discretion of the indemnifying party, payments of
                  claims to an indemnified party may be made by wire transfer of
                  immediately available funds within 10 business days after the
                  date of the notice of sums due and owing provided for in
                  Section 9.2, in lieu of the release of shares from the
                  Purchaser or Shareholder Escrows.

                                       31
<PAGE>

         (b)      In the event that Purchaser, in accordance with Section
                  9.5(a), does not elect to pay any liabilities owing by it by
                  wire transfer, the number of Contingent Shares to be released
                  with respect to any such liability shall be determined by
                  dividing the amount of such liability by $.95 and multiplying
                  the result thus obtained by 1.15.

         (c)      In the event that a Shareholder does not elect to pay
                  liabilities owing by wire transfer, the number of Escrowed to
                  be released from Escrow to Purchaser with respect to such
                  liability and to be cancelled shall be determined by dividing
                  the amount of such liability by $.95.
