          2.3 POST-CLOSING DATE PURCHASE PRICE ADJUSTMENT.

               (a) The target working capital of the Company as of the Closing
          Date is $0 (such target working capital, the "TARGET WORKING
          CAPITAL"). "Working Capital" means the current assets of the Company
          minus all current liabilities of the Company; provided, however, that
          the following shall be excluded from the calculation of Working

          extent any such specific intercompany payables are expressly assumed
          by Buyer at the Closing (e.g., accrued bonuses and related benefit
          costs, Seller funded infrastructure costs, etc.); (ii) deferred
          revenues; and (iii) income taxes, whether prepaid, paid, owing or
          deferred. Notwithstanding anything to the contrary herein, for
          purposes of this Section 2.3, Working Capital shall include any income
          tax liability related to deferred revenues which originate after
          December 31, 2005 and which remain on the Closing Balance Sheet, but
          only to the extent Seller has received cash for such deferred
          revenues, and such income tax liability shall be calculated using a
          combined overall tax rate of 40% for Federal and state income tax
          purposes.

               (b) Within 90 days following the Closing Date, Buyer shall
          deliver to Seller a balance sheet of the Company as of the open of
          business on the Closing Date (the "CLOSING BALANCE SHEET") and a
          statement setting forth a reasonably detailed calculation of Working
          Capital as of the Closing Date ("CLOSING WORKING CAPITAL"), prepared
          in accordance with the books and records of the Company (the "CLOSING
          WORKING CAPITAL STATEMENT"). The Closing Balance Sheet and the Closing
          Working Capital Statement shall be prepared in accordance with GAAP
          applied using the same accounting methods, practices, principles,
          policies and procedures, with consistent classifications, judgments
          and valuation and estimation methodologies that were used in the
          preparation of the Company's Unaudited Financial Statements. The
          Closing Working Capital shall be consistent with the calculation set
          forth in SECTION 2.3(B) OF THE DISCLOSURE SCHEDULE of Working Capital
          as of December 31, 2005.

               (c) ACCEPTANCE OF STATEMENTS; DISPUTE PROCEDURES. The Closing
          Balance Sheet and the Closing Working Capital Statement (and the
          computation of Closing Working Capital indicated thereon) delivered by
          Buyer to Seller shall be conclusive and binding upon the parties
          unless Seller, within 30 days after delivery to the Seller of the
          Closing Balance Sheet and the Closing Working Capital Statement,
          notifies Buyer in writing that Seller disputes any of the amounts set
          forth therein, specifying in reasonable detail the nature of the
          dispute and the basis therefor. The parties shall in good faith
          attempt to resolve any dispute and, if the parties so resolve such
          dispute, the Closing Balance Sheet and the Closing Working Capital
          Statement (and the computation of Closing Working Capital indicated
          thereon), as amended to the extent necessary to reflect the resolution
          of the dispute, shall be conclusive and binding on the parties. If the
          parties do not reach agreement in resolving the dispute within 60 days
          after notice is given by Seller to Buyer pursuant to the second
          preceding sentence, the parties shall submit the dispute to a partner
          at the New York office of Deloitte & Touche LLP (the "ARBITER") for
          resolution. If the parties cannot agree on the selection of a partner
          to act as Arbiter, the parties shall request the American Arbitration
          Association to appoint such a partner, and such appointment shall be
          conclusive and binding on the parties. Promptly, but no later than 30
          days after acceptance of his or her appointment as Arbiter, the
          Arbiter shall determine (it being understood that in making such
          determination, the Arbiter shall be functioning as an expert and not
          as an arbitrator), based solely on written submissions by Buyer and
          Seller, and not by independent review, only those issues in dispute
          and shall render a written report as to the resolution of the dispute
          and the resulting computation of the Closing Working Capital which
          shall be conclusive and binding on the parties. In resolving any
          disputed item, the Arbiter (x) shall be bound by the provisions of
          this SECTION 2.3 and (y) may not assign a value to any item greater
          than the greatest value for such items claimed by either party or less
          than the smallest value for such items claimed by either party. The
          fees, costs and expenses of the Arbiter shall be allocated to and
          borne by Buyer and Seller based on the inverse of the percentage that
          the Arbiter's determination (before such allocation) bears to the
          total amount of the total items in dispute as originally submitted to
          the Arbiter. For example, should the items in dispute total in amount
          to $1,000 and the Arbiter awards $600 in favor of Seller's position,
          60% of the costs of its review would be borne by Buyer and 40% of the
          costs would be borne by Seller.

               (d) PAYMENT. Upon final determination of Closing Working Capital
          as provided in SECTION 2.3(C) above, (A) if Closing Working Capital is
          greater than Target Working Capital, the Purchase Price shall be
          increased by the excess of Closing Working Capital over Target Working
          Capital and Buyer shall promptly, but no later than five business days
          after such final determination, pay the amount of such difference to
          Seller, and (B) if Closing Working Capital is less than Target Working
          Capital, the Purchase Price shall be decreased by the excess of Target
          Working Capital over Closing Working Capital and Seller shall
          promptly, but no later than five business days after such final
          determination, pay to Buyer the amount of such difference.

          2.4 CLOSING. The closing of the transactions contemplated by this
     Agreement (the "CLOSING") shall take place at the offices of Bryan Cave
     LLP, 120 Broadway, Suite 300, Santa Monica CA 90401, at 9:00 a.m., local
     time, on the second Tuesday of June, 2006 or, if the conditions to the

               (b) Buyer shall not, for a period (the "REVIEW PERIOD") of four
          years after the Closing Date or such longer period as retention
          thereof is required by applicable law or by any record retention
          agreements entered into with any Taxing Authority, dispose of or

          4.1 ORGANIZATION. Seller is a corporation duly organized, validly
     existing and in good standing under the laws of the State of California.
     The Company is a corporation duly organized, validly existing and in good
     standing under the laws of the State of Nevada. The Company has all
     requisite corporate and other power and corporate authority to own, lease
     and operate its properties and to carry on its operations as now being
     conducted. The Company is duly qualified, authorized or licensed to do
     business as a foreign corporation and is in good standing in each
     jurisdiction in which the property owned, leased or operated by the Company
     or the nature of the business conducted by the Company makes such
     qualification necessary, except in any such jurisdiction where the failure
     to be so duly qualified, authorized or licensed and in good standing would
     not have a Material Adverse Effect. The Company has previously made
     available to Buyer complete and correct copies of the Company's Articles of
     Incorporation and Bylaws of the Company, as currently in effect (the
     "COMPANY CHARTER DOCUMENTS"). The Company has no direct or indirect
     subsidiaries or any other equity interest in any Person.

          4.2 AUTHORIZATION. Seller has the requisite corporate power and
     authority to execute and deliver this Agreement and each other agreement,
     document, instrument or certificate contemplated hereby or to be executed
     and delivered by Seller in connection with the consummation of the
     transactions contemplated by this Agreement (the "TRANSACTION DOCUMENTS")
     and consummate the transactions contemplated hereby. The execution,
     delivery and performance of this Agreement and each of the Transaction
     Documents, and the consummation of the transactions contemplated hereby and
     thereby, have been duly authorized and approved by all necessary corporate
     action on the part of Seller. This Agreement has been duly executed and
     delivered by Seller and constitutes, and, when executed and delivered, each
     of the Transaction Documents will constitute (assuming in each case the
     valid authorization, execution and delivery of such agreement by Buyer),
     the legal valid and binding obligation of Seller, enforceable against
     Seller in accordance with its terms, except that (a) such enforcement may
     be subject to any bankruptcy, insolvency, reorganization, moratorium,
     fraudulent transfer or other laws, now or hereafter in effect, relating to
     or limiting creditors' rights generally and (b) the remedy of specific
     performance and injunctive and other forms of equitable relief may be
     subject to equitable defenses and to the discretion of the court before
     which any proceeding therefor may be brought.

          4.3 COMMON STOCK. The authorized capital stock of the Company consists
     solely of 20,000,000 shares of Common Stock, par value $0.01 per share, of
     which the Shares are the only shares issued and outstanding. All of the
     Shares are duly authorized, validly issued, fully paid and non assessable
     and were not issued in violation of any law or any preemptive or similar
     rights. There are no outstanding securities convertible into, exchangeable
     for, or carrying the right to acquire, equity securities of the Company,
     nor are there any subscriptions, warrants, options, rights or other
     arrangements or commitments (other than this Agreement) which could
     obligate the Company to issue or Seller to sell any shares of Common Stock.
     There are no obligations, contingent or otherwise, of the Company to (i)
     repurchase, redeem or otherwise acquire any shares of capital stock or
     other equity of the Company, or (ii) provide material funds to, or make any
     material investment in (in the form of a loan, capital contribution or
     otherwise), or provide any guarantee with respect to the obligations of,
     any Person. There are no outstanding share appreciation, phantom shares,
     profit participation or similar rights of the Company. There are no voting
     agreements, voting trusts, irrevocable proxies or other contracts or
     understandings to which the Company is a party or is bound with respect to
     the voting of any shares of capital stock or other equity of the Company.

          4.4 OWNERSHIP OF THE SHARES. Seller is the sole record and beneficial
     owner of the Shares and the Shares constitute all of the capital stock of
     the Company owned by Seller. Seller has good title to such Shares, free and
     clear of all Liens.

          4.5 CONSENTS AND APPROVALS; NO VIOLATIONS. Except for applicable
     requirements of the Hart Scott Rodino Antitrust Improvement Act of 1976, as
     amended (the "H-S-R ACT"), neither the execution and delivery of this
     Agreement or the Transaction Documents nor the consummation by Seller of
     the transactions contemplated hereby will (a) conflict with or result in
     any breach of any provision of the Company Charter Documents or the
     Articles of Incorporation or Bylaws of Seller; (b) require any filing with,
     or the obtaining of any Permit, order, authorization, consent or approval
     of, any Governmental Authority; (c) except as set forth in SECTION 4.5 OF

     acceleration under, any of the terms, conditions or provisions of any
     Contract to which the Company or Seller is a party or by which the Company
     or Seller or any of their assets may be bound; or (d) violate any judgment,
     order, injunction, decree, ruling, writ, assessment or arbitration
     applicable to the Company or Seller, excluding from the foregoing clauses
     (b), (c) and (d), such requirements, conflicts, defaults, rights or
     violations which, individually or in the aggregate, would not have or be
     reasonably likely to have a Material Adverse Effect and would not adversely
     affect or be reasonably likely to adversely affect the ability of Seller to
     consummate the transactions contemplated by this Agreement.

          material to the operation of the Company's business currently being
          used by the Company are in good operational condition and repair,
          normal wear and tear excepted, other than items currently under, or

          or by which the properties or assets of the Company is bound, except
          those that are terminable by the Company without penalty on 60 or
          fewer days notice. All of the items of personal property under the
          Personal Property Leases are in good condition and repair (ordinary
          wear and tear excepted) and are suitable for the purposes used, and
          such property is in all material respects in the condition required of
          such property by the terms of the lease applicable thereto during the
          term of the lease. Seller has made available to Buyer true, correct

          moratorium and similar laws affecting creditor rights and remedies
          generally and subject, as to enforceability, to general principles of
          equity (regardless of whether enforcement is sought in a proceeding at
          law or in equity). Each of the Personal Property Leases is in full
          force and effect and the Company has not received or given notice of
          any default or event that, to the knowledge of Seller, with notice or
          lapse of time, or both, would constitute a default by the Company
          under any Personal Property Leases and, to the knowledge of Seller, no
          other party is in material default thereof, and no party to the
          Personal Property Leases has exercised any termination rights with
          respect thereto.

          Company Intellectual Property Rights that are Registered Intellectual
          Property Rights ("COMPANY REGISTERED IP") and all material
          unregistered copyrights, trademarks and service marks. All Company
          Registered IP is currently in compliance with formal legal

          fees or taxes or actions due within 90 days after the Closing Date.
          There are no proceedings or actions pending or, to the knowledge of
          Seller, threatened before any court or tribunal (including the PTO or
          equivalent authority) related to any such Company Registered IP other
          than those set forth in SECTION 4.12(G)(II) OF THE DISCLOSURE
          SCHEDULE. Seller is not aware of any reasonable basis for any
          assertions by any third party that any Company Registered IP is not
          valid and enforceable.

               (h) Neither the Company nor Seller is aware of any claim
          currently being asserted by any Person or of any facts that cause
          Seller to believe, that any aspects of the Business, the Company
          Intellectual Property Rights, the Company Technology, the Licensed
          Intellectual Property Rights or the Licensed Technology, or the use
          thereof in connection with the conduct of the business and operations
          of the Company infringe or misappropriate the Intellectual Property
          Rights of any Person or constitute unfair competition or trade
          practices under the laws of any jurisdiction, and to the knowledge of
          Seller, the conduct of the business and operations of the Company
          (including the development, manufacture, sale and distribution of
          Products) does not infringe or misappropriate, and has not infringed
          or misappropriated, the Intellectual Property Rights of any Person.
          SECTION 4.12(H) OF THE DISCLOSURE SCHEDULE lists all agreements
          pursuant to which the Company has agreed to indemnify any third party
          against any charge of infringement or misappropriation of any

               (i) To the knowledge of Seller, no Person is infringing or
          misappropriating any Company Intellectual Property Rights.

               (j) The Company has the right to use, pursuant to valid licenses,
          all Licensed Intellectual Property Rights and Licensed Technology that
          are material to the Business as currently conducted by the Company.
          Except with respect to licenses of Software generally available for an
          annual license fee of no more than $25,000, SECTION 4.12(J) OF THE
          DISCLOSURE SCHEDULE sets forth a complete and accurate list of all
          contracts, licenses and agreements pursuant to which the Company
          licenses or otherwise is authorized to use any Technology or
          Intellectual Property Rights used in the businesses of the Company,
          ("LICENSE IN AGREEMENTS"). Neither the execution and delivery of this
          Agreement nor the consummation by Seller of the transactions
          contemplated hereby will violate, conflict with or result in a default
          (or any event that, with notice or lapse of time or both, would
          constitute a default) under, or give rise to any right of termination
          or cancellation under, any of the terms, conditions or provisions of
          any such material License In Agreement, excluding such violations,
          conflicts, defaults and rights which become applicable as a result of
          the business or activities in which Buyer is or proposes to be engaged
          or as a result of any acts or omissions by, or the status of or any
          facts pertaining to, Buyer. Except with respect to licenses of
          Software generally available for an annual license fee of no more than
          $25,000 and the licenses set forth on SECTION 4.12(J) OF THE
          DISCLOSURE SCHEDULE, the Company is not required, obligated, or under
          any liability under any agreements to make any payments by way of
          royalties, fees or otherwise to any third party with respect to use of
          any Intellectual Property Rights or Technology used in the business of
          the Company. No loss or expiration of any Intellectual Property Rights
          licensed to the Company under any License In Agreement is pending or
          reasonably foreseeable or, to the knowledge of Seller, threatened
          other than pursuant to the scheduled expiration of the term of any
          License In Agreement in the ordinary course. The execution, delivery
          and performance by the Company or Seller of this Agreement, and the
          consummation of the transactions contemplated hereby, will not result
          in the loss or impairment of, or give rise to any right of any third
          party to terminate or reprice or otherwise modify any of the Company's
          rights or obligations under any License In Agreement.

               (m) Except as set forth in SECTION 4.12(M) OF THE DISCLOSURE
          SCHEDULE, Seller has no knowledge of any facts or circumstances that

          application or registration with respect to any Intellectual Property
          Rights owned by the Company.

               (n) The Software owned by the Company operates substantially as
          described in the user manuals and does not contain any program

          malicious logic, worm, trojan horse, bug, error, defect or trap door,
          that is capable of deleting, disabling, deactivating, interfering
          with, or otherwise harming the Software or Buyer's hardware, data, or
          computer programs or codes, or that is capable of providing access or
          produce modifications not authorized by Buyer (collectively,
          "DISABLING PROCEDURES"). Such representation and warranty applies
          regardless of whether such Disabling Procedures are authorized by
          Seller to be included in the Software.

          of ERISA, for the benefit of any Company Employee or any former
          employee of the Company, or with respect to which the Company has any
          liability, contingent or direct (a "PLAN" and collectively, the
          "PLANS"). The Company has made available to Buyer correct and complete
          copies to the extent applicable of (i) each of the Plans including all

          regulations, and each of the Plans intended to be "qualified" within
          the meaning of Section 401(a) of the Code, has been determined by the
          Internal Revenue Service (the "IRS") to be so qualified and Seller

          such qualification. None of the Plans is subject to Title IV of ERISA
          and neither Seller, the Company nor any of their ERISA Affiliates have
          within the past 6 years maintained, sponsored, contributed to or been
          obligated to contribute to any "employee benefit plan" (as defined in
          Section 3(3) of ERISA) subject to Title IV of ERISA, including any
          multiemployer plan (as defined in Section 3(37) of ERISA). No Plan

          payable to any third party, including Seller or any of its Affiliates;

          licensees and others having business relationships with the Company
          and (B) to preserve the present business operations, organization and
          goodwill of the Company.

          6.2 ACCESS TO INFORMATION.

               (a) Until the Closing, Seller shall cause the Company to (i) give
          Buyer and its authorized representatives reasonable access to all
          books, records, offices and other facilities and properties of the
          Company; (ii) permit Buyer to make such inspections thereof as Buyer

          HOWEVER, that Buyer shall in each instance give reasonable prior
          notice to Seller and that any such investigation shall be conducted
          during normal business hours under the supervision of Seller's or the
          Company's personnel and in such a manner as to maintain the
          confidentiality of this Agreement and the transactions contemplated
          hereby and shall not interfere unreasonably with the business
          operations of the Company; and, PROVIDED, FURTHER, that any such
          disclosure shall not be required if it would violate any laws or the
          terms or conditions of any contracts or adversely affect the ability
          of Seller or the Company to assert attorney-client, attorney work
          product or other similar privilege.

<PAGE>

               (b) Any disclosure whatsoever during such investigation by Buyer
          shall not constitute an enlargement of or additional representations
          or warranties of Seller beyond those specifically set forth in Article
          IV of this Agreement.

               (c) All information concerning the Company and/or Seller
          furnished or provided by the Company or Seller to Buyer or its
          representatives (whether furnished before or after the date of this
          Agreement) shall be held subject to a confidentiality agreement among
          the Company, Seller and Buyer dated as of December 5, 2005 (the
          "CONFIDENTIALITY AGREEMENT").

          6.3 CONSENTS.

               (a) Each of Seller and Buyer shall cooperate, and use its
          Reasonable Efforts, to make all filings and obtain all licenses,
          Permits, consents, approvals, authorizations, qualifications and
          orders of Governmental Authorities necessary to consummate the
          transactions contemplated by this Agreement. Without limiting the
          generality of the foregoing, Seller and Buyer shall (i) make any and
          all notifications and filings required to be made to any court,
          administrative agency or commission or other governmental agency,
          authority or instrumentality having supervisory or regulatory
          authority with respect to the relevant party or parties to this
          Agreement in connection with the transactions contemplated by this
          Agreement; and (ii) file any Notification and Report Forms and related
          material that such party may be required to file with the Federal
          Trade Commission and the Antitrust Division of the United States
          Department of Justice under the H-S-R Act, use its Reasonable Efforts
          to cause the early termination of the waiting period(s) and to respond
          to any request for additional information and documentary material, as
          may be necessary, proper or advisable in connection therewith. Any and
          all filing fees in respect of such filings shall be paid by Buyer.
          Notwithstanding the foregoing, neither Buyer nor any of its Affiliates
          shall be required, in connection with the matters set forth in this
          Section 6.3, to hold separate (including by trust or otherwise) or
          divest any of their respective businesses, product lines or assets.

               (b) Seller shall use and shall cause the Company to use its
          Reasonable Efforts to obtain any third party consents or approvals
          that Buyer may reasonably request in connection with the consummation
          of the transactions contemplated by this Agreement. Buyer agrees to
          provide such assurances as to financial capability, resources and
          creditworthiness as may be reasonably requested by any third party
          whose consent or approval is sought hereunder.

               (c) With respect to any agreements for which any required consent
          or approval is not obtained prior to the Closing, Seller and Buyer
          shall each use its Reasonable Efforts to obtain any such consent or
          approval after the Closing Date until such consent or approval has
          been obtained.

          6.4 REASONABLE EFFORTS. Each of Seller and Buyer shall cooperate, and
     use its Reasonable Efforts to take, or cause to be taken, all actions, and
     to do, or cause to be done, all things necessary, proper or advisable under
     applicable laws and regulations to consummate the transactions contemplated
     by this Agreement (including satisfaction, but not waiver, of the closing
     conditions set forth herein).

                                       32
<PAGE>

          6.5 COVENANT TO SATISFY CONDITIONS. Seller will use its Reasonable
     Efforts to ensure that the conditions set forth in Article VII hereof are
     satisfied, insofar as such matters are within the control of Seller. Buyer
     will use its Reasonable Efforts to ensure that the conditions set forth in
     Article VII hereof are satisfied, insofar as such matters are within the
     control of Buyer. Notwithstanding the foregoing, none of the parties to
     this Agreement shall be required to waive any condition herein to its
     obligations at the Closing or to incur any substantial cost not otherwise
     required under this Agreement. Seller and Buyer further covenant and agree,
     with respect to a threatened or pending preliminary or permanent injunction
     or other order, decree or ruling or statute, rule, regulation or executive
     order that would adversely affect the ability of the parties hereto to
     consummate the transactions contemplated hereby, to use all Reasonable
     Efforts to prevent or lift the entry, enactment or promulgation thereof, as
     the case may be. Notwithstanding the foregoing, neither Buyer nor any of
     its Affiliates shall be required, in connection with the matters set forth
     in this Section 6.5, to hold separate (including by trust or otherwise) or
     divest any of their respective businesses, product lines or assets.

          6.6 PUBLIC ANNOUNCEMENTS. Prior to the Closing, except as otherwise
     agreed to by the parties and except for disclosures made by Buyer to its
     lenders or potential lenders pursuant to customary confidentiality
     provisions, the parties shall not issue any report, statement or press
     release or otherwise make any public statements with respect to this
     Agreement and the transactions contemplated hereby without obtaining the
     prior approval of the other party hereto, which approval will not be
     unreasonably withheld or delayed, unless, in the reasonable judgment of the
     party intending to make such release, disclosure is otherwise required by
     applicable law or by the applicable rules of any stock exchange on which
     such party or its Affiliates lists securities, PROVIDED, that, to the
     extent required by applicable law, the party intending to make such release
     shall use its Reasonable Efforts consistent with such applicable law to
     consult with the other party with respect to the text thereof. Upon the
     Closing, Seller and Buyer will consult with each other with respect to the
     issuance of a joint report, statement or press release with respect to this
     Agreement and the transactions contemplated hereby.

          6.7 USE OF "TEKELEC" NAME. From and after the Closing, Buyer agrees
     not to use and shall cause the Company and Buyer's affiliates not to use
     the "TEKELEC" name in any manner in any part of the world as part of their
     company names or in any manner in connection with their respective
     businesses.

          6.8 EMPLOYEES; EMPLOYEE BENEFITS.

               (a) Prior to the Closing Date, Seller shall transfer the
          employment of all Company Employees to the Company. Seller shall be
          solely responsible for any Liability incurred in connection with such
          transfers of employment (including, without limitation, any
          Liabilities under any Plan or under the WARN Act or any other
          applicable law). In connection with such transfers of employment,
          Seller shall obtain federal and state taxpayer identification numbers
          for the Company, activate income and employment tax accounts, and
          report and remit appropriate taxes with respect to compensation earned
          by Company Employees prior to the Closing Date, as well as ensure that
          the Company Employees receive workers' compensation coverage (or, to
          the extent it is not possible to complete such actions before the
          Closing Date, the Seller shall use Reasonable Efforts to initiate such
          actions). Because the Company does not directly employ most employees,
          and most employees who perform services for the Company are employed
          directly by Seller, certain Intellectual Property Rights and
          Technology used in the current operation of the Company's business may
          be owned by Seller pursuant to confidentiality, nondisclosure and
          invention assignment agreements between Seller and the Company
          Employees listed on SECTION 4.16 OF THE DISCLOSURE SCHEDULE and by
          virtue of the employer--employee relationship between Seller and the
          Company Employees. Prior to the Closing, Seller shall assign to the
          Company all of the Seller's right, title and interest to all
          Intellectual Property Rights and Technology (other than the
          intellectual property and associated rights comprising and related to
          the Company's ASi 4000 technology) used in the current operations of
          the Company's business that was developed or created by the Company
          Employees, and Seller shall assign to the Company all of Seller's
          right, title and interest under such agreements between Seller and
          such Company Employees. The covenants set forth in SECTION 4.12(A) OF
          THE DISCLOSURE SCHEDULE are hereby incorporated into this Agreement in
          their entirety.

                                       33
<PAGE>

               (b) Buyer agrees that prior to the Closing, it will not require
          or request of Seller or the Company that Seller or the Company
          terminate any Company Employees. For a one-year period following the
          Closing, Buyer shall, or shall cause the Company to, provide each
          Company Employee who continues as an employee of the Company (an
          "EMPLOYEE") with benefits that are at least substantially comparable
          in the aggregate to those benefits provided to similarly situated
          employees of Buyer (other than equity and performance based
          compensation). Buyer shall give full credit for all service with the
          Company or any Affiliate thereof, and any predecessor thereto to the
          extent that service with such predecessor entity was recognized under
          the applicable Plan of the Company or any Affiliate, to each Employee
          for purposes of vesting and eligibility, including waiting periods
          relating to preexisting conditions under medical plans (except for
          purposes of determining the amount of any benefit under any defined
          benefit pension plan and eligibility for early retirement or any
          subsidized benefit), any employee benefit plan (including any
          "employee benefit plan" as defined in Section 3(3) of ERISA)
          maintained by Buyer or its subsidiaries (including any vacation or
          accrued sick pay plan or policy) in which the Employees participate on
          or after the Closing Date. Prior to the Closing, the Company shall
          furnish Buyer with a list of the length of service with the Company or
          its Affiliates for each of the Employees. For purposes of computing
          deductible amounts (or like adjustments or limitations on coverage)
          under any employee welfare benefit plan (including any "employee
          welfare benefit plan" as defined in Section 3(1) of ERISA), expenses
          and claims previously recognized for similar purposes under the
          applicable welfare benefit plan of the Company or any Affiliate shall
          be credited or recognized under the comparable plan maintained after
          the Closing Date by Buyer or its subsidiaries in which the Employees
          participate.

                                       34
<PAGE>

               (c) Notwithstanding anything in paragraph (a) of this Section to
          the contrary, if any Employee is discharged by the Company on or
          within 12 months after the Closing Date, then the Company shall be
          responsible for severance for such discharged Employee, such severance
          payable to be determined at the greater of the Company's severance
          policy as set forth in SECTION 6.8(C) OF THE DISCLOSURE SCHEDULE or
          Buyer's then current severance policy, giving effect to the provisions
          of Section 6.8(b). The Company shall be responsible and assume all
          liability for all notices or payments due to any Employee, and all
          notices, payments, fines or assessments due to any government
          authority, pursuant to any applicable foreign, Federal, state or local
          law, common law, statute, rule or regulation with respect to the
          employment, discharge or layoff of employees by the Company after the
          Closing, including WARN and any rules or regulations as have been
          issued in connection with the foregoing.

               (d) Buyer shall cause the Company to indemnify, defend and hold
          harmless the officers, directors and employees of the Company to the
          same extent that such persons are entitled to indemnification as of
          the date hereof pursuant to the Company's Articles of Incorporation,
          Bylaws and any agreements between such persons and the Company, for
          any acts or omissions prior to the Closing Date. Until the seventh
          anniversary of the Closing Date, Buyer shall provide policies of
          officers' and directors' liability insurance with reputable and
          financially sound carriers of at least the same coverage and amount
          and containing terms and conditions that are no less favorable in
          respect of acts or omissions occurring prior to the Closing Date
          covering each such person currently covered by such policies in effect
          of the date hereof.

               (e) Seller shall retain all liabilities for claims incurred by an
          Employee (and his or her eligible spouse and dependents) on or prior
          to the Closing Date under the Plans that are welfare benefit plans
          within the meaning of Section 3(1) or ERISA and all short term
          disability and salary continuation plans or arrangements (the "WELFARE
          PLANS"). For this purpose claims under any medical, dental, vision or
          prescription drug plan will be deemed to be incurred on the date that
          the service giving rise to such claim is performed and not when such
          claim is made; PROVIDED, HOWEVER, that with respect to claims relating
          to hospitalization the claim will be deemed to be incurred on the
          first day of such hospitalization and not on the date that such
          services are performed. Claims for disability under any long or short
          term disability plan or arrangement will be incurred on the date the
          Employee is first absent from work because of the condition giving
          rise to such disability and not when the Employee is determined to be
          eligible for benefits under the applicable Welfare Plan or other
          arrangement. Seller will provide any continuation coverage required
          under COBRA to each "qualified beneficiary" (as defined in COBRA)
          whose first "qualifying event" (as defined in COBRA) occurs on or
          prior to the Closing Date. The Company shall be responsible for the
          continuation of health plan coverage, in accordance with the
          requirements of COBRA for any Employee or a qualified beneficiary
          under a Company health plan who first has a qualifying event after the
          Closing Date.

                                       35
<PAGE>

               (f) Effective as of the Closing Date, Seller shall transfer, or
          cause to be transferred, to Buyer an amount, in cash, equal to the
          excess, if any, of the aggregate 2006 contributions of all Employees
          then participating in Seller's or its Affiliate's flexible benefits
          plan (the "SELLER FLEXIBLE BENEFITS PLAN"), over the aggregate 2006
          reimbursements to all Employees under such plan. Buyer shall cause
          such amounts to be credited to each such employee's accounts under
          Buyer's (or one of its affiliate's) corresponding flexible benefit
          plan (the "BUYER FLEXIBLE BENEFITS PLAN") which shall be established
          and in effect for such employees as of the Closing Date, and all
          claims for reimbursement which have not been paid as of the date of
          the transfer to Buyer and credited under the Buyer Flexible Benefits
          Plan shall be paid pursuant to and under the terms of the Buyer
          Flexible Benefits Plan. In connection with such transfer, Buyer shall
          deem that such employees' deferral elections made under the Seller
          Flexible Benefits Plan for the 2006 calendar year shall continue in
          effect under the Buyer Flexible Benefits Plan for the remainder of the
          2006 calendar year following the Closing Date.

               (g) Buyer shall cause the Company to recognize and provide all
          accrued but unused vacation and personal days as of the Closing Date
          to the extent reflected on the Most Recent Balance Sheet.

               (h) On the date of this Agreement, Buyer and each of the key
          Company Employees designated by Buyer shall enter into agreements
          which shall provide for the terms of such employees employment after
          the Closing Date.

               (i) To the extent Seller and the Company deem advisable, Company
          Employees shall become fully vested in their accounts under the
          Tekelec 401(k) Plan.

          6.9 CERTAIN TAX MATTERS.

               (a) Seller shall accurately prepare and file all federal Income
          Tax Returns and all other Income Tax Returns with respect to the
          Company for all periods ending on or prior to the Closing Date. Such
          Tax Returns shall include any gain or income recognized by the Company
          as a result of: (i) the distribution by the Company of shares of stock
          of Santera Systems Inc. to Seller in November, 2003; (ii) the
          distribution by the Company to Seller of intellectual property and
          associated rights comprising and related to the ASi 4000 technology on
          or before the Closing Date; and (iii) the balance in the deferred
          revenue account of the Company on December 31, 2005 determined
          pursuant to Revenue Procedure 2004-34. Seller shall be responsible for
          the payment of all Taxes with respect to such Tax Returns. Seller
          shall also be responsible for (i) the accurate preparation of all
          Non-Income Tax Returns that are required to be filed with respect to
          the Company that are due before the Closing Date and (ii) for the
          payment of all Taxes payable with respect thereto. Buyer and its
          authorized representatives shall have the right to review and audit
          all Income Tax Returns of the Company that are required to be filed
          after the Closing Date, provided that in the case of the federal
          Income Tax Return, such review and audit shall be limited to the
          portions that relate to the Company and the supporting detail and work
          papers. Buyer and Seller agree to consult and resolve in good faith
          any issues arising as a result of the review and audit of such Tax
          Return by Buyer or its authorized representative. If, after the
          Closing Date, Buyer or the Company pays any such Taxes for which
          Seller is responsible, Seller shall reimburse Buyer or the Company
          within 5 days after the date Seller is notified by Buyer or the
          Company that such Taxes were paid. The covenants set forth in SECTION
          4.18(A) OF THE DISCLOSURE SCHEDULE are hereby incorporated into this
          Agreement in their entirety.

                                       36
<PAGE>

               (b) Buyer or the Company shall accurately prepare and file all
          Non-Income Tax Returns for the Company for all periods ending prior to
          the Closing Date that are required to be filed after the Closing Date.
          Seller shall cooperate with Buyer in filing and causing to be filed
          such Tax Returns. Seller shall be responsible for payment of, and
          shall pay when due, any Non-Income Taxes shown due on such returns or
          that are otherwise payable with respect to such Tax Returns. If, after
          the Closing Date, Buyer or the Company pays any such Non-Income Taxes
          for which Seller is responsible, Seller shall reimburse Buyer or the
          Company within 5 days after the date Seller is notified by Buyer or
          the Company that such Taxes were paid.

               (c) Buyer shall prepare or cause to be prepared and file or cause
          to be filed all Tax Returns for the Company for all Straddle Periods.
          All Taxes with respect to the Company attributable to Pre-Closing
          Periods shall be allocated to and paid by Seller, except to the extent
          such Taxes have been previously paid by Seller including amounts paid
          in respect of estimated Taxes, and all Taxes with respect to the
          Company attributable to Post-Closing Periods shall be allocated to and
          paid by Buyer. In the case of any Taxes with respect to the Company
          for a Straddle Period, the portion of such Taxes that are allocated to
          the Pre-Closing Period shall (x) be deemed to be the amount that would
          be payable if the relevant Tax period ended as of the Closing Date
          pursuant to an interim closing of the books in the case of all Income
          Taxes with respect to the Company and any Non-Income Taxes with
          respect to the Company not described in (y) below and (y) in the case
          of Non-Income Taxes with respect to the Company that cannot be
          allocated based upon an interim closing of the books (e.g., property
          or net worth taxes), be deemed to the amount of such Taxes for the
          entire Taxable period multiplied by a fraction, the numerator of which
          is the total number of days in that portion of such Taxable period
          ending on the Closing Date and the denominator of which is the total
          number of days in such Tax period. Seller shall pay to Buyer within 5
          days after the date Seller is notified that Taxes with respect to the
          Company attributable to a Straddle Period were paid by Buyer an amount
          equal to the portion of such Taxes attributable to the Pre-Closing
          Period and shall indemnify Buyer against such portion of such Taxes.
          All determination necessary to give effect to the foregoing
          allocations shall be made in a manner consistent with prior practice
          of Seller.

               (d) With respect to any Tax Return of the Company required to be
          filed by Buyer or the Company after the Closing Date for Pre-Closing
          Periods or Straddle Periods, Seller and its authorized representatives
          shall have the right to review and audit such Tax Returns prior to
          filing of the Tax Returns. Buyer and Seller agree to consult and
          resolve in good faith any issues arising as a result of the review and
          audit of such Tax Return by Seller or its authorized representative.

               (e) Buyer covenants that without the prior consent of Seller,
          which shall not be unreasonably withheld, it will not, and will not
          cause or permit the Company or any Affiliate of Buyer, to make or
          change any Tax election, amend any Tax Return or take any Tax position
          on any Tax Return, that results in any increased Tax liability of the
          Company or Seller in respect of any Pre-Closing Tax Period.
          Notwithstanding the foregoing, consent of Seller shall not be required
          to the extent any foregoing action by Buyer or Company is required by
          applicable law.

                                       37

               (f) Buyer and Seller agree to furnish or cause to be furnished to
          each other, upon written request, as promptly as practicable, such
          information (including access to books and records) and assistance
          relating to the Company as is reasonably necessary for the filing of
          any Tax Return, for the preparation for any audit, and for the
          prosecution or defense of any claim, suit or proceeding relating to
          any proposed adjustment. Buyer and Seller shall cooperate with each
          other in the conduct of any audit or other proceedings involving the
          Company for any Tax purposes and each shall execute and deliver such
          powers of attorney and other documents as are necessary to carry out
          the intent of this subsection. Any Tax audit or other Tax proceeding
          shall be deemed to be a third party claim subject to the procedures
          set forth in Section 9.6 of this Agreement.

               (g) Buyer shall promptly pay or shall cause prompt payment to be
          made to Seller of all refunds of Taxes and interest thereon received
          by, or credited against the Tax liability of Buyer, any Affiliate of
          Buyer or the Company attributable to Taxes paid by Seller or the
          Company with respect to any Pre-Closing Tax Period or any portion of
          the Straddle Period prior to the Closing Date. If, with respect to a
          Tax Return required to be filed by the Company, Seller reasonably
          determines that the Company is entitled to file a claim for refund or
          an amended Tax Return with respect to a Pre-Closing Tax Period, Buyer
          shall, upon Seller's reasonable request, cause the Company to file all
          such claims or amended Tax Returns; provided that Buyer shall not be
          required to cause the Company to file any such claim or amended Tax
          Return if so doing (i) could have the effect of increasing the Tax
          liability of Buyer or the Company in any Post-Closing Tax Period or
          (ii) in Buyer's reasonable judgment is contrary to applicable law.
          Seller shall reimburse Buyer and Company for all reasonable expenses
          incurred to comply with Seller's request, including any third party
          professional, legal or accounting fees.

               (h) Notwithstanding any other provisions of this Agreement to the
          contrary, all transfer, documentary, sales, use, stamp, registration,
          and other such Taxes and fees (including any penalties and interest)
          incurred in connection with the transactions contemplated by this
          Agreement shall be paid by Buyer. Buyer shall at its own expense
          accurately file or cause to be filed all necessary Tax Returns and
          other documentation with respect such Taxes and timely pay all such
          Taxes.

          6.10 EXCLUSIVITY. From and after the date of this Agreement until the
     earlier of the Closing Date or termination of this Agreement pursuant to
     Article VIII, Seller shall not, directly or indirectly, solicit offers
     from, or in any manner initiate or encourage the submission of any proposal
     of, or enter into negotiations or agreement with any third party relating
     to the acquisition of all or substantially all of the Company's capital
     stock or assets, including any acquisition structured as a tender offer,
     exchange offer, merger, consolidation, recapitalization or share exchange.

          6.11 DISCLOSURE SCHEDULE. Notwithstanding any specific reference to
     the disclosure of any matter pursuant to any Section of the Disclosure
     Schedule, all disclosures made pursuant to any Section hereunder or on the
     Disclosure Schedule shall be deemed made for all other Sections to which
     such disclosure may apply to the extent its relevance to such other
     Sections is reasonably apparent, and any headings or captions on any
     Section herein or therein are for convenience of reference only.

          6.12 NON-COMPETITION; NON-SOLICITATION.

               (a) For a period of three years from and after the Closing Date,
          Seller shall not, and shall cause its majority owned subsidiaries not
          to, directly or indirectly, own, manage, engage in, operate, control,
          work for, consult with, render services for, do business with,
          maintain any interest in (proprietary, financial or otherwise) or
          participate in the ownership, management, operation or control of, any
          business, whether in witness corporate, proprietorship or partnership
          form or otherwise, engaged in the work force management call center
          contact business as currently conducted by the Company (a "RESTRICTED
          BUSINESS"); PROVIDED, HOWEVER, that the restrictions contained in this
          Section 6.12(a) shall not restrict the acquisition by Seller, directly
          or indirectly, of less than 5% (in the aggregate) of the outstanding
          capital stock of any publicly traded company engaged in a Restricted
          Business.

               (b) For a period of two years from and after Closing Date, except
          with Buyer's consent, Seller shall not, and shall cause its directors,
          officers, employees and majority owned subsidiaries not to, directly
          or indirectly (i) cause, solicit, induce or encourage any employees of
          the Company to leave such employment or hire, employ or otherwise
          engage any such individual; or (ii) cause, induce or encourage any
          material actual or prospective client, customer, supplier or licensor
          of the Company (including any former customer of the Company and any
          Person that becomes a customer of the Company after the Closing) or
          any other Person who has a material business relationship with the
          Company to terminate or modify any such actual or prospective
          relationship.

               (c) For the avoidance of doubt, and as a material inducement to
          Seller to enter into this Agreement, the parties agree that,
          notwithstanding anything to the contrary in the foregoing provisions
          of Section 6.12, in the event that a person, firm, corporation or
          other business acquires Seller or any of its majority-owned
          subsidiaries by merger, consolidation or otherwise (any such person,
          firm, corporation or other business, an "Acquiror"), such Acquiror and
          its Affiliates (other than Seller) shall not be deemed to be in
          breach, default or violation of any of the covenants set forth in
          Section 6.12 above unless, in taking any actions that would constitute
          a breach or violation of the obligation of Seller under the provisions
          of Section 6.12, such Acquiror or any of its Affiliates (other than
          Seller) uses: (a) the Company's corporate name or trademarks in
          existence as of the Closing Date; (b) any Company Technology or
          Company Intellectual Property Rights in existence as of the Closing
          Date; or (c) the services of any individuals who are employees of the
          Company as of the Closing Date.

               (d) The covenants and undertakings contained in this Section 6.12
          relate to matters which are of a special, unique and extraordinary
          character and a violation of any of the terms of this Section 6.12
          will cause irreparable injury to Buyer, the amount of which will be
          impossible to estimate or determine and which cannot be adequately
          compensated. Accordingly, the remedy at law of any breach of this
          Section 6.13 will be inadequate. Therefore, Buyer will be entitled to
          seek a temporary and permanent injunction, restraining order or other
          equitable relief from any court of competent jurisdiction in the event
          of any breach of this Section 6.12 without the necessity of proving
          actual damage or posting any bond whatsoever. The rights and remedies
          provided this Section 6.12 are cumulative and in addition to any other
          rights and remedies which Buyer may have hereunder or at law or in
          equity.

          6.13 REMITTANCES OF RECEIVABLES. After the Closing, if Seller or any
     of its Affiliates receive any accounts receivables or other amounts that
     are otherwise properly due and owing to the Company or Buyer, Seller shall
     remit, or shall cause to be remitted, such amount to Buyer within 5
     Business Days of receipt of such funds.

          6.14 TERMINATION OF CERTAIN CONTRACTS. On or prior to the Closing
     Date, Seller agrees to terminate, or cause to be terminated, all Contracts
     set forth in Section 4.24 of the Disclosure Schedules.

          6.15 AUDITED FINANCIAL STATEMENTS. At least five Business Days prior
     to the Closing, Seller shall deliver to Buyer audited balance sheets for
     the fiscal years ended December 31, 2005, 2004 and 2003, and the related
     statements of income, changes in stockholders' equity and cash flow for the
     fiscal years ended December 31, 2005, 2004 and 2003 (the "AUDITED FINANCIAL
     STATEMENTS"). The Audited Financial Statements shall (i) be prepared in
     accordance with GAAP and the books and records of the Company and (ii)
     present fairly, in all material respects, the financial position of the
     Company as of the date thereof, and the results of operations of the
     Company for the period indicated.

          6.16 BLUE PUMPKIN SOFTWARE LICENSE. On or prior to the Closing Date,
     the Company shall assign to Buyer all of its rights and obligations under
     the license granted to it under the Blue Pumpkin Licensed Patents, as
     defined below, pursuant to the Confidential Settlement and Cross License
     Agreement dated as of April 6, 2006 by and between Blue Pumpkin Software
     LLC, Blue Pumpkin Software, Inc. and the Company (the "BLUE PUMPKIN
     CROSS-LICENSE AGREEMENT"); PROVIDED, HOWEVER, that Buyer acknowledges and
     agrees that the Company may assign, on or prior to the Closing Date, its
     right to receive royalty payments under Section 6 of the Blue Pumpkin
     Cross-License Agreement to Seller. "BLUE PUMPKIN LICENSED PATENTS" shall
     have the meaning set forth in Section 1.5 of the Blue Pumpkin Cross-License
     Agreement.

     shall forthwith be given by the party so terminating to the other party and
     this Agreement shall terminate and the transactions contemplated hereby

          hereof, to the party furnishing the same, and all confidential

               (b) All filings, applications and other submissions made pursuant
          hereto shall, at the option of Seller, and to the extent practicable,

               (c) There shall be no liability or obligation hereunder on the
          part of Seller or Buyer or any of their respective Affiliates, except
          that Seller or Buyer, as the case may be, may have liability to the
          other party if the basis of termination is a willful, material breach
          by Seller or Buyer, as the case may be, of one or more of the
          provisions of this Agreement, and except that the obligations provided
          for in Sections 6.2(c), 8.2(a), 8.2(b) and 10.1 hereof shall survive
          any such termination.

     after the end of the period of performance thereunder (in each case, as
     applicable, the "INDEMNITY PERIOD"); PROVIDED, HOWEVER, that any
     obligations under Sections 9.2 and 9.3 shall not terminate with respect to
     any Damages as to which the Person to be indemnified shall have given
     notice (stating in reasonable detail the basis of the claim for
     indemnification) to the indemnifying party in accordance with Section 9.4
     before the termination of the applicable Indemnity Period.

          9.2 SELLER'S AGREEMENT TO INDEMNIFY. Subject to the terms and
     conditions set forth herein, from and after the Closing, Seller shall

     successors and assigns (collectively, the "BUYER INDEMNITEES") from and
     against all liability, demands, claims, actions or causes of action,
     assessments, losses, damages, costs and expenses (including the reasonable
     fees and expenses of attorneys and experts) (collectively "DAMAGES")
     asserted against or incurred by any Buyer Indemnitee, and pay to the
     applicable Buyer Indemnitee, the amount of all Damages, whether or not
     involving a third party claim, resulting from or arising out of (i) any
     breach or inaccuracy in any representation or warranty made by Seller under

     and pay to the applicable Seller Indemnitee the amount of all Damages,
     whether or not involving a third party claim, resulting from or arising out

          9.4 NOTICE OF CLAIMS.

               (a) Upon obtaining knowledge of any Damages, the party entitled
          to indemnification (the "INJURED PARTY") shall promptly deliver
          written notice (a "NOTICE OF CLAIM") to the party liable for such
          indemnification (the "INDEMNIFYING PARTY") which Notice of Claim shall
          set forth in reasonable detail and to the extent then known the basis
          of the claim for Damages and, to the extent reasonably practicable, a
          reasonable estimate of the amount thereof. The failure of an Injured
          Party to timely deliver a Notice of Claim to the Indemnifying Party
          shall not release the Indemnifying Party from its indemnity
          obligations under this Article IX, except to the extent that the
          Indemnifying Party is materially prejudiced in its ability to defend
          such claim.

               (b) The Injured Party and Indemnifying Party shall attempt for
          not less than 30 days to negotiate a mutually satisfactory resolution
          of the matter set forth in a Notice of Claim. In the event such
          parties are not able to agree on a mutually satisfactory resolution,
          either party may seek to resolve the depute by litigation in any court
          of competent jurisdiction in accordance with the provision of Section
          10.8 hereof.

          9.5 GENERAL LIMITATIONS; EXCLUSIVE REMEDY.

               (a) Each Indemnifying Party shall be obligated to indemnify the
          Injured Party only for those claims giving rise to Damages as to which
          the Injured Party has given to the Indemnifying Party written notice
          thereof prior to the end of the applicable Indemnity Period.

               (b) The provisions of this Article IX shall constitute the
          exclusive remedy for money damages of the parties with respect to any
          and all Damages resulting from or arising out of any breach of any
          representation, warranty, covenant or other provision of this
          Agreement, or otherwise resulting from or arising out of the
          transactions contemplated hereby and which may be asserted on or after
          the Closing (other than any claim relating to fraud).

               (c) Seller's obligations to indemnify the Buyer Indemnitees
          pursuant to Section 9.2 hereof with respect to a breach of a
          representation, warranty, covenant or agreement (excluding the
          covenants and agreements set forth in Sections 2.3, 3.2 and 6.9(a))
          contained in this Agreement are subject to the following limitations:

                    (i) No indemnification shall be made by Seller unless the
               aggregate amount of Damages exceeds $2,000,000 and, in such
               event, indemnification shall be made by Seller from first dollar
               provided that such limitation shall not apply to Damages related
               to breaches of Sections 4.2 (Authorization), 4.3 (Common Stock),
               4.4 (Ownership of the Shares) or 4.18 (Taxes);

                    (ii) In no event shall Seller's aggregate obligation to
               indemnify the Buyer Indemnitees exceed 20% of the Purchase Price,
               PROVIDED that such aggregate obligation shall not apply to
               Damages related to breaches of Sections 4.2 (Authorization), 4.3
               (Common Stock), 4.4 (Ownership of the Shares) or 4.18 (Taxes).

                                       45
<PAGE>

               (d) The amount of any Damages that may be subject to
          indemnification hereunder shall be reduced by any amount actually
          recovered by an Injured Party under insurance policies with respect to
          such Damages.

               (e) Solely for purposes of calculating any Damages hereunder as a
          result of any breach or inaccuracy in any representation or warranty
          or breach or violation of any covenant or agreement made in this
          Agreement, any materiality or Material Adverse Effect qualifications
          in the representations, warranties, covenants and agreements shall be
          disregarded.

          9.6 THIRD PARTY INDEMNIFICATION.

               (a) If the Injured Party settles or compromises any third-party
          claims, or initiates action which is for the purpose in whole or in
          part of causing a claim to be asserted, prior to giving a Notice of
          Claim to the Indemnifying Party, the Indemnifying Party shall be
          released from its indemnity obligation.

               (b) With respect to any action or any claim set forth in a Notice
          of Claim relating to a third-party claim, the Indemnifying Party may
          defend, in good faith and at its expense, any such claim or demand,
          and the Injured Party, at its expense, shall have the right, but not
          the obligation, to participate in (but not control) at its expense in
          the defense of any such third-party claim so long as (i) the
          Indemnifying Party shall have acknowledged in writing to the relevant
          Injured Party its obligation to indemnify such Injured Party as
          provided hereunder, (ii) the third-party claim involves primarily
          money damages and (iii) the Indemnifying Party conducts the defense of
          the third-party claim actively and diligently. So long as the
          Indemnifying Party is defending any such third-party claim, the
          Injured Party shall not settle or compromise such third-party claim
          without the consent of the Indemnifying Party. If such claim is
          settled by the Injured Party without the Indemnifying Party's consent,
          the Injured Party shall be deemed to have waived all rights hereunder
          for money damages arising out of such claim. The Indemnifying Party
          may settle or compromise such third-party claim without the consent of
          the Injured Party, if the settlement or compromise involves only the
          payment of monetary damages and included in such settlement or
          compromise as an unconditional term thereof is the delivery to Injured
          Party of a written release from all liability in respect of such
          third-party claim. Otherwise, the Indemnifying Party may not settle or
          compromise such third-party claim without the consent of the Injured
          Party, which consent shall not be unreasonably withheld. The Injured
          Party shall make available to the Indemnifying Party or its
          representatives all records and other materials reasonably required
          for use in contesting any third-party claim. The Injured Party shall
          cooperate fully with the Indemnifying Party in the defense of all such
          claims.

                                       46
<PAGE>

               (c) If the Indemnifying Party fails to assume the defense of any
          such third-party claims, within thirty (30) days after receipt of a
          Notice of Claim (or such shorter period of time that the Injured Party
          may be required to respond to any suit or governmental action), the
          Injured Party shall have the right to undertake the defense, settle or
          compromise any such third-party claim at the risk and expense of the
          Indemnifying Party, subject to the right of the Indemnifying Party to
          assume the defense of such claim at any time prior to settlement,
          compromise or final determination thereof. The failure of the
          Indemnifying Party to respond in writing to the aforesaid notice of
          the Injured Party with respect to such third-party claim within thirty
          (30) days after receipt thereof shall be deemed an election not to
          defend same. The Indemnifying Party will not, however, be responsible
          for any Damages if and to the extent that they arise from action taken
          or omitted to be taken by the Injured Party in bad faith,
          fraudulently, negligently or as a result of a breach of this Agreement
          by the Injured Party.

          9.7 INDEMNITY PAYMENTS. Except as provided by applicable law, for Tax
     purposes any indemnification payments shall be treated as adjustments to
     purchase price.

                                   ARTICLE X
                                  MISCELLANEOUS

          10.1 FEES AND EXPENSES. Except as otherwise provided herein, each of
     Seller, on the one hand, and Buyer, on the other hand, shall pay all fees
     and expenses incurred by, or on behalf of, such party in connection with,
     or in anticipation of, this Agreement and the consummation of the
     transactions contemplated hereby, including fees and expenses of attorneys,
     accountants and financial advisors, except any fees or expenses incurred to
     obtain the third party consents, approvals, waivers and notices set forth
     in SECTION 7.3(F) OF THE DISCLOSURE SCHEDULE shall be borne by Seller. In
     addition, each of Seller, on the one hand, and Buyer, on the other hand,
     shall indemnify and hold harmless the other party from and against any and
     all claims or liabilities for financial advisory and finders' fees incurred
     by reason of any action taken by such party or otherwise arising out of the
     transactions contemplated by this Agreement by any person claiming to have
     been engaged by such party.

          10.2 FURTHER ASSURANCES. From time to time after the Closing Date, at
     the reasonable request of another party hereto and at the expense of the
     party so requesting, each of the parties hereto shall execute and deliver
     to such requested party such documents and take such other action as such
     requesting party may reasonably request in order to consummate more
     effectively the transactions contemplated hereby. Seller shall not, in
     connection therewith or as a result thereof, incur any legal liability
     beyond that provided for in this Agreement.

          10.3 NOTICES. All notices, requests, demands, waivers and other
     communications required or permitted to be given under this Agreement shall
     be in writing and may be given by any of the following methods: (a)

     Neither this Agreement nor any of the rights, interests or obligations
     hereunder shall be assigned, directly or indirectly, including by operation
     of law, by any party hereto without the prior written consent of the other
     party hereto; provided however that Buyer may assign its rights and
     obligations hereunder to any subsidiary of Buyer. In the event that Buyer
     exercises its right to assign this Agreement, Buyer shall deliver an
     executed guarantee to Seller in the form of Exhibit C hereto.

          10.6 NO THIRD PARTY BENEFICIARIES. This Agreement is solely for the
     benefit of Seller, and its successors and permitted assigns, with respect
     to the obligations of Buyer under this Agreement, and for the benefit of
     Buyer, and its respective successors and permitted assigns, with respect to
     the obligations of Seller, under this Agreement, and this Agreement shall
     not be deemed to confer upon or give to any other third party any remedy,
     claim, liability, reimbursement, cause of action or other right, except for
     the parties entitled to the benefits of Sections 6.8(c), 9.2 and 9.3.

          10.7 INTERPRETATION.

               (a) The article and section headings contained in this Agreement
          are solely for the purpose of reference, are not part of the agreement
          of the parties and shall not in any way affect the meaning or
          interpretation of this Agreement.

               (b) The parties have participated substantially in the
          negotiation and drafting of this Agreement and agree that no ambiguity
          herein should be construed against the draftsman.

          10.8 JURISDICTION AND CONSENT TO SERVICE. Each of Seller and Buyer (a)
     agrees that any suit, action or proceeding arising out of or relating to
     this Agreement may be brought solely in the state courts having competent
     jurisdiction within the County of New York in the State of New York or
     Federal courts having competent jurisdiction within the southern district
     of New York; (b) consents to the exclusive jurisdiction of each such court
     in any suit, action or proceeding relating to or arising out of this
     Agreement; (c) waives any objection which it may have to the laying of
     venue in any such suit, action or proceeding in any such court; and (d)
     agrees that service of any court paper may be made in such manner as may be
     provided under applicable laws or court rules governing service of process.

          10.9 ATTORNEYS' FEES. In the event that litigation arises in
     connection with enforcement of any provision of this Agreement, the
     prevailing party in such litigation shall be entitled to recover its
     reasonable attorneys' fees and expenses, in addition to any other relief to
     which it may be deemed entitled.

          10.10 GOVERNING LAW. This Agreement shall be governed by and construed
     in accordance with the laws of the State of New York (regardless of the
     laws that might otherwise govern under applicable principles of conflicts
     of laws thereof) as to all matters, including but not limited to matters of
     validity, construction, effect, performance and remedies.

          10.11 SPECIFIC PERFORMANCE. The parties acknowledge and agree that any
     breach of the terms of this Agreement would give rise to irreparable harm
     for which money damages would not be an adequate remedy and accordingly the
     parties agree that, in addition to any other remedies, each shall be
     entitled to enforce the terms of this Agreement by a decree of specific
     performance without the necessity of proving the inadequacy of money
     damages as a remedy.

          10.12 ENTIRE AGREEMENT. This Agreement, the Confidentiality Agreement
     and the Disclosure Schedule and other documents referred to herein or
     delivered pursuant hereto which form a part hereof constitute the entire
     agreement among the parties with respect to the subject matter hereof and
     supersede all other prior agreements and understandings, both written and
     oral, between the parties or any of them with respect to the subject matter
     hereof.

          10.13 AMENDMENT, MODIFICATION AND WAIVER. This Agreement may be
     amended, modified or supplemented at any time by written agreement of
     Seller and Buyer. Any failure of Seller or Buyer to comply with any term or
     provision of this Agreement may be waived, with respect to the Buyer, on
     the one hand, by Seller, and with respect to Seller, on the other hand, by
     Buyer, by an instrument in writing signed by or on behalf of the
     appropriate party, but such waiver of failure to insist upon strict
     compliance with such term or provision shall not operate as a waiver of, or
     estoppel with respect to, any subsequent or other failure to comply.

          10.14 COUNTERPARTS. This Agreement may be executed in counterparts,
     each of which shall be deemed to be an original, but which together shall
     constitute one and the same agreement.

                               AMENDMENT NO. 2 TO
                        ASSET PURCHASE AND SALE AGREEMENT

     THIS AMENDMENT NO. 2 TO ASSET PURCHASE AND SALE AGREEMENT (this "AMENDMENT
NO. 2") is made and entered into as of March 27, 2006, by and between Dictaphone
Corporation, a Delaware corporation ("Dictaphone"), and NICE Systems Inc., a
Delaware corporation ("BUYER"), in connection with that certain Asset Purchase
and Sale Agreement, dated as of April 11, 2005, by and among Buyer and
Dictaphone, as amended by Amendment No. 1 to the Asset Purchase and Sale
Agreement dated as of May 31, 2005 between Dictaphone and Buyer (as so amended,
the "Agreement").

                                   WITNESSETH:

     WHEREAS, pursuant to Section 11.12 thereof, the Agreement may be amended
only by a written agreement signed by Buyer and Dictaphone; and

     WHEREAS, Buyer and Dictaphone are desirous of further amending the
Agreement as set forth herein;

     NOW, THEREFORE, in consideration of the premises, the parties hereto,
intending to be legally bound, hereby agree as follows:

     1. DEFINED TERMS

     All capitalized terms used in this Amendment No. 2 and not otherwise
defined herein shall have the respective meanings assigned thereto in the
Agreement.

     2. FINAL ADJUSTMENT TO PURCHASE PRICE; CLOSING BALANCE SHEET

     (a) Pursuant to Section 2.5(b) of the Agreement, and without limiting the
Buyer's rights under Article 9 of the Agreement, Dictaphone will pay to Buyer
the sum of Two-Million Dollars (US$2,000,000.00) (such sum being the "FINAL
ADJUSTMENT AMOUNT") as a final adjustment (decrease) to the Purchase Price under
the Agreement, to be considered as such for accounting and all Tax purposes.
Such Final Adjustment Amount shall be paid by deduction from the Indemnification
Escrowed Funds in accordance with Section 4 of this Amendment No. 2. In
addition, the parties agree that Buyer shall be entitled to all previously
undistributed interest and other investment income earned with respect to the
Indemnification Escrowed Funds.

     (b) Dictaphone will deliver to Buyer as promptly as practicable following
the date hereof (and in any event, no later than April 15, 2006), an audited
Closing Balance Sheet that reflects a Net Adjusted Working Capital Level that is
less than $0.00 by an amount which is equal to the Final Adjustment Amount.
Buyer and Dictaphone hereby acknowledge and agree that upon payment of the Final
Adjustment Amount, all obligations and rights of either party under Section
2.5(b)(iv) and (v) of the Agreement are terminated, PROVIDED THAT Buyer shall
retain all rights under Article 9 except as modified by this Amendment No. 2.

     3. INDEMNIFICATION MODIFICATIONS.

     (a) Buyer hereby waives any rights to indemnification by Dictaphone or any
successor or assign of Dictaphone arising from Section 9.1(b). The parties agree
that this waiver shall not reduce or impair Buyer's ability to pursue remedies
or implement any procedure contemplated in Article 9 with respect to
indemnification claims arising from Section 9.1(a) or Section 9.1(c).

     (b) Dictaphone hereby waives any rights to indemnification by Buyer or any
successor or assign of Buyer arising from Section 9.2(b). The parties agree that
this waiver shall not reduce or impair Dictaphone's or any successor or assign
of Dictaphone's ability to pursue remedies or implement any procedure
contemplated in Article 9 with respect to indemnification claims arising from
Section 9.2(a) or Section 9.2(c).

     4. RELEASE OF ESCROW. Notwithstanding anything to the contrary in Section
2.7(a) of the Agreement or Section 4(b) of the Escrow Agreement, the parties
hereto agree that the Final Adjustment Amount shall be paid out from the
Indemnification Escrowed Funds to the Buyer or its designee, and the remaining
$1,000,000 of the Indemnification Escrowed Funds shall be paid to Dictaphone or
its designee. The parties further agree that all previously undistributed
interest and other investment income earned with respect to the Indemnification
Escrowed Funds shall be paid to the Buyer or its designee. Within five (5)
Business Days following the delivery to Buyer by Dictaphone of the Closing

hereto shall execute and deliver to the Escrow Agent a Joint Written Direction
in the form attached hereto as Exhibit A to effectuate the agreed payments. Any
fees and expenses of the Escrow Agent shall be borne equally by the parties as
provided in Section 10 of the Escrow Agreement.
