The date on which the Closing occurs is hereinafter referred to as the "Closing Date." Section 1.03. Effective Time.

Section 1.04. Effect of the Merger. At the Effective Time, the effect of the Merger shall be as provided in Section 259 of the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time all the property, rights, privileges, powers and franchises of Merger Sub and the Company shall vest in the Surviving Corporation, and all debts, obligations, liabilities and duties of each of Merger Sub and the Company shall become the debts, obligations, liabilities and duties of the Surviving Corporation. CORPDAL:59869.4 22768-00022 2 <PAGE> Section 1.05. Certificate of Incorporation. At the Effective Time, the Certificate of Incorporation of the Company shall be the Certificate of Incorporation of Merger Sub as in effect immediately prior to the Effective Time. Section 1.06.

At the Effective Time and without further action on the part of the Company or VTEL, the Bylaws of the Surviving Corporation shall be the Bylaws of Merger Sub in effect as of the Effective Time. Section 1.07. Directors and Officers. The directors of Merger Sub immediately prior to the Effective Time shall be the directors of the Surviving Corporation, each to hold office in accordance with the Certificate of Incorporation and Bylaws of the Surviving Corporation, and the officers of the Company immediately prior to the Effective Time shall be the officers of the Surviving Corporation, in each case until their respective successors are duly elected or appointed and qualified.

ARTICLE II CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES Section 2.01. Merger Consideration: Conversion and Cancellation of Securities. At the Effective Time, by virtue of the Merger and without any action on the part of the VTEL Companies, the Company or the holders of any of the Company's securities: (a) Subject to the other provisions of this Article II, each share of common stock, par value $.001 per share, of the Company ("Company Common Stock") issued and outstanding immediately prior to the Effective Time (excluding any Company Common Stock described in Section 2.01(e) of this Agreement) shall be converted into the right to receive .46 of one fully paid and nonassessable share of common stock, par value $.0l per share, of VTEL ("VTEL Common Stock") (the "Common Stock Conversion Ratio"). (b) Subject to the other provisions of this Article II, each share of Series C Preferred Stock, par value $.001 per share, of the Company ("Series C Preferred Stock") issued and outstanding immediately prior to the Effective Time (excluding any Series C Preferred Stock described in Section 2.01(e) of this Agreement and any Dissenting Shares, as herein defined) shall be converted into the right to receive 3.15 fully paid and CORPDAL:59869.4 22768-00022 3 <PAGE> nonassessable share of VTEL Common Stock (the "Series C Preferred Stock Conversion Ratio"). (c) Notwithstanding the foregoing, if between the date of this Agreement and the Effective Time the outstanding shares of VTEL Common Stock or Company Common Stock shall have been changed into a different number of shares or a different class, by reason of any stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares, the Common Stock Conversion Ratio and the Series C Preferred Stock Conversion Ratio shall be correspondingly adjusted to reflect such stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares. (d) As a result of their conversion pursuant to Section 2.01(a) and Section 2.01(b), all shares of Company Common Stock and Series C Preferred Stock shall cease to be outstanding and shall automatically be canceled and retired. Each certificate previously evidencing Company Common Stock outstanding immediately prior to the Effective Time (other than Company Common Stock described in Section 2.01(e) of this Agreement) ("Converted Common Shares") shall thereafter represent, subject to Section 2.02(d) of this Agreement, the right to receive that number of shares of VTEL Common Stock into which the shares of Company Common Stock represented by such certificate have been converted pursuant to subsection (a) of this Section 2.01 determined pursuant to the Common Stock Conversion Ratio and, if applicable, the right to receive cash pursuant to Section 2.02(d) of this Agreement ("Common Stock Merger Consideration"). Each certificate previously evidencing Series C Preferred Stock outstanding immediately prior to the Effective Time (other than Series C Preferred Stock described in Section 2.01(e) of this Agreement and any Dissenting Shares) (the "Converted Series C Preferred Shares" and, together with the Converted Common Shares, the "Converted Shares") shall thereafter represent, subject to Section 2.02(d) of this Agreement, the right to receive that number of shares of VTEL Common Stock into which the shares of Series C Preferred Stock represented by such certificate have been converted pursuant to subsection (b) of this Section 2.01 determined pursuant to the Series C Preferred Stock Conversion Ratio and, if applicable, the right to receive cash pursuant to Section 2.02(d) of this Agreement (the "Series C Preferred Stock Consideration" and, with the Common Stock Consideration, the "Merger Consideration"). The holders of certificates previously evidencing Converted Shares shall cease to have any rights with respect to such Converted Shares except the right to receive the Merger Consideration applicable thereto and as otherwise provided herein or by law. Such certificates previously evidencing Converted Shares shall be exchanged for certificates evidencing whole shares of VTEL Common Stock issued in consideration therefor upon the surrender of such certificates in accordance with the provisions of Section 2.02 of this Agreement. No fractional shares of VTEL Common Stock shall be issued and, in lieu thereof, a cash payment shall be made pursuant to Section 2.02(d) of this Agreement. CORPDAL:59869.4 22768-00022 4 <PAGE> (e) Notwithstanding any provision of this Agreement to the contrary, each share of Company Common Stock or Series C Preferred Stock held in the treasury of the Company and each share of Company Common Stock owned by VTEL or any direct or indirect wholly owned subsidiary of VTEL or of the Company immediately prior to the Effective Time shall be canceled and extinguished without any conversion thereof and no payment shall be made with respect thereto. (f) Each share of common stock, par value $.0l per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and exchanged for one newly and validly issued, fully paid and nonassessable share of common stock of the Surviving Corporation. Section 2.02. Exchange Agency; Surrender of Certificates. (a) Exchange Fund. At or prior to the Effective Time, VTEL shall deposit, or cause to be deposited, with a bank or trust company designated by VTEL (the "Exchange Agent"), for the benefit of the holders of Converted Shares, for exchange in accordance with this Article II, through the Exchange Agent (i) certificates evidencing a number of shares of VTEL Common Stock equal to the product of the Common Stock Conversion Ratio multiplied by the number of Converted Common Shares issued and outstanding immediately prior to the Effective Time, (ii) certificates evidencing a number of shares of VTEL Common Stock equal to the product of the Series C Preferred Stock Conversion Ratio multiplied by the number of shares of Series C Preferred Stock issued and outstanding immediately prior to the Effective Time, and (iii) cash in an amount sufficient to provide for the payments to be made in lieu of issuing any fractional shares of VTEL Common Stock as provided in Section 2.02(d) of this Agreement. Additionally, subject to the provisions of subsection (e) of this Section 2.02, VTEL shall, if and when a payment date has occurred with respect to a dividend or distribution that has been declared subsequent to the Effective Time, deposit with the Exchange Agent an amount in cash (or property of like kind to that which is the subject of such dividend or distribution) equal to the dividend or distribution per share of VTEL Common Stock times the number of shares of VTEL Common Stock evidenced by certificates theretofore representing Converted Shares that have not theretofore been surrendered for exchange in accordance with this Section 2.02. The certificates and cash (and property, if any) deposited with the Exchange Agent in accordance with this Section 2.02(a) are hereinafter referred to as the "Exchange Fund." The Exchange Agent shall, pursuant to irrevocable instructions, deliver VTEL Common Stock (and any dividends or distribution related thereto) and/or cash, as described above, in exchange for surrendered certificates pursuant to the terms of this Agreement out of the Exchange Fund. (b) Exchange Procedures. As soon as practicable after the Effective Time, VTEL shall cause the Exchange Agent to send to each record holder of Company Common Stock and Series C Preferred Stock at the Effective Time (i) a letter of transmittal (which CORPDAL:59869.4 22768-00022 5 <PAGE> shall specify that delivery shall be effected, and risk of loss and title to the certificates theretofore representing Company Common Stock or Series C Preferred Stock (the "Certificates") shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in such form and contain such other provisions as VTEL and the Company shall reasonably determine), and (ii) instructions for use in effecting the surrender of the Certificates in exchange for certificates representing shares of VTEL Common Stock and any cash in lieu of fractional shares, into which the shares of Company Common Stock or Series C Preferred Stock represented by such Certificate or Certificates shall have been converted pursuant to this Agreement. Upon surrender of a Certificate for cancellation to the Exchange Agent, together with such letter of transmittal, duly executed, the holder of such Certificate shall be entitled to receive in exchange therefor, a certificate representing that number of whole shares of VTEL Common Stock which such holder has the right to receive pursuant to the provisions of this Article II and cash in the amount such holder has the right to receive pursuant to such provisions, and the Certificate so surrendered shall forthwith be canceled. In the event of a transfer of ownership of Company Common Stock or Series C Preferred Stock which is not registered in the transfer records of the Company, a certificate evidencing the proper number of shares of VTEL Common Stock may be issued to the transferee if the Certificate evidencing the Company Common Stock or Series C Preferred Stock shall be surrendered to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer taxes have been paid. Until surrendered for exchange in accordance with the provisions of Section 2.02 of this Agreement, each Certificate theretofore representing Converted Shares (other than shares of Company Common Stock and Series C Preferred Stock to be canceled pursuant to Section 2.01(e) of this Agreement and any Dissenting Shares) shall from and after the Effective Time represent for all purposes only the right to receive the applicable Merger Consideration as set forth in this Agreement. If any holder of Converted Shares shall be unable to surrender such holder's Certificates because such Certificates have been lost or destroyed, such holder may deliver in lieu thereof an affidavit and indemnity bond in form and substance and with surety reasonably satisfactory to VTEL. No interest shall be paid on any Merger Consideration payable to former holders of Converted Shares. (c) Distributions with Respect to VTEL Common Stock. No dividends or other distributions declared or made after the Effective Time with respect to VTEL Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate theretofore representing shares of Company Common Stock or Series C Preferred Stock with respect to any shares of VTEL Common Stock evidenced thereby, and no Merger Consideration shall be paid to any such holders until the holder of such Certificate shall surrender such Certificate theretofore representing shares of Company Common Stock or shares of Series C Preferred Stock . Subject to applicable laws, following surrender of any such Certificate, there shall be paid to the holder of the certificates evidencing whole shares of VTEL Common Stock issued in exchange therefor, without interest, (i) promptly following the surrender of such Certificate and in addition CORPDAL:59869.4 22768-00022 6 <PAGE> to the amount of any cash payable with respect to a fractional share of VTEL Common Stock to which such holder is entitled pursuant to Section 2.02(d) of this Agreement, the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of VTEL Common Stock and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to surrender and a payment date occurring after surrender payable with respect to such whole shares of VTEL Common Stock. (d) No Fractional Shares. No certificates or scrip evidencing fractional shares of VTEL Common Stock shall be issued upon the surrender for exchange of Certificates, and such fractional share interests shall not entitle the owner thereof to any rights of a stockholder of VTEL. In lieu of any such fractional shares, (i) each holder of a Certificate previously evidencing Company Common Stock or Series C Preferred Stock, upon surrender of such Certificate for exchange pursuant to this Article II, shall be paid an amount in cash (without interest), rounded to the nearest cent, determined by multiplying (A) the Average Closing Price by (B) the fractional interest to which such holder would otherwise be entitled (after taking into account all shares of Company Common Stock or Series C Preferred Stock held of record by such holder at the Effective Time). "Average Closing Price" means the average closing sales price of the VTEL Common Stock on The NASDAQ Stock Market (or such other quotation system or securities exchange on which the VTEL Common Stock is then quoted or listed) as reported by the Wall Street Journal for the 20 consecutive trading days beginning 22 trading days prior to the scheduled Closing Date as provided in Section 1.02 hereof. (e) Termination of Exchange Fund. Any portion of the Exchange Fund that remains unclaimed by the former holders of Converted Shares on the first anniversary of the Closing Date shall be delivered to VTEL, upon demand, and any former holders of Converted Shares who have not theretofore complied with this Article II shall thereafter look only to VTEL for the Merger Consideration and dividends or distributions to which they are entitled, without any interest thereon. Neither VTEL nor the Company shall be liable to any former holder of Converted Shares for any Merger Consideration (or dividends or distributions with respect thereto) or cash delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. (f) Withholding. VTEL (or any affiliate thereof) shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any former holder of Converted Shares such amounts as VTEL (or any affiliate thereof) is required to deduct and withhold with respect to the making of such payment under the Code or any other provision of federal, state, local or foreign tax law and VTEL agrees to remit to the proper taxing authority such amounts so withheld. To the extent that amounts are so withheld by VTEL, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the former holder of the Converted Shares in respect of which such deduction and withholding was made by VTEL. CORPDAL:59869.4 22768-00022 7 <PAGE> Section 2.03. Stock Transfer Books. At the Effective Time, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers of shares of Company Common Stock or Series C Preferred thereafter on the records of the Company. If, after the Effective Time, Certificates are presented to the Surviving Corporation, they shall be canceled and exchanged for the Merger Consideration, deliverable in respect thereof pursuant to this Agreement in accordance with the procedures set forth in this Article II. Certificates surrendered for exchange by any person constituting an "affiliate" of the Company for purposes of Rule 145(c) under the Securities Act of 1933, as amended (the "Securities Act"), shall not be exchanged until VTEL has received a written agreement from such person as provided in Section 6.04. Section 2.04. Dissenters' Rights. (a) The holders of shares of Company Common Stock shall not be entitled to appraisal rights. Notwithstanding anything in this Agreement to the contrary, each share of Series C Preferred Stock issued and outstanding immediately prior to the Effective Time and held by stockholders who have not voted such shares in favor of the Merger or consented thereto in writing and qualify under and have complied with all of the provisions of Section 262 of the DGCL ("Dissenting Shares") shall not, by virtue of the Merger, be converted into the right to receive the Series C Preferred Stock Consideration but such stockholder shall be entitled to receive payment of the appraised value of such shares of Series C Preferred Stock held by them in accordance with the provisions of Section 262 of the DGCL; provided, however, that if any holder of Dissenting Shares (i) subsequently delivers a written withdrawal of his demand for appraisal rights (with the written consent of VTEL if such written withdrawal is not made within 60 days after the Effective Time), or (ii) fails to perfect dissenter's rights as provided in Section 262 of the DGCL, or (iii) if neither any holder of Dissenting Shares nor the Surviving Corporation has filed a petition demanding a determination of the value of Dissenting Shares within the time provided in Section 262 of the DGCL, the Dissenting Shares held by such holder or holders (as the case may be) shall thereupon be deemed to have been converted into and to have become exchangeable for, as of the Effective Time, the right to receive the Series C Preferred Stock Consideration, as provided in this Agreement without any interest thereon. (b) The Company shall give VTEL (i) prompt notice of any written demands for appraisal, withdrawal of demands for appraisal and any other instruments served pursuant to Section 262 of the DGCL and (ii) the opportunity to direct all negotiations and proceedings with respect to demands for appraisal under Section 262 of the DGCL. The Company agrees that prior to the Effective Time, it will not, without the prior written consent of VTEL, voluntarily make or agree to make any payment with respect to, or settle or offer to settle, any such demands. CORPDAL:59869.4 22768-00022 8 <PAGE> (c) Each holder of Dissenting Shares who becomes entitled, pursuant to the provisions of Section 262 of the DGCL, to payment of his or its Dissenting Shares shall receive payment therefor after the Effective Time from the Surviving Corporation (but only after the amount thereof shall have been agreed upon or finally determined pursuant to such provisions) and such shares shall be canceled.

The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which such person reasonably believed to be in or not opposed to the best interests of the Company, and, with respect to any criminal action or proceeding, that such person and reasonable cause to believe that his conduct was unlawful. In the event of any such claim, action, suit, proceeding or investigation (whether asserted or commenced before or after the Effective Time), the Company, VTEL or the Surviving Corporation, as the case may be, will be entitled to participate in and, to the extent that it may wish, to assume the defense thereof; provided, however, that if any Indemnified Party (or group of Indemnified Parties) reasonably believes that it is advisable for such Indemnified Parties to be represented by separate counsel as a result of a conflict, on any significant issue between the positions of the Indemnified Party (or group of Indemnified Parties) and the Company, VTEL or the Surviving Corporation, as the case may be, as determined under applicable standards of professional conduct or if the Company, VTEL or the Surviving Corporation shall promptly fail to assume responsibility for such defense, such Indemnified Party (or group of Indemnified Parties) may retain counsel satisfactory to such Indemnified Party (or group of Indemnified Parties), who will represent such Indemnified Party (or group of Indemnified Parities), and the Company, VTEL or the Surviving Corporation, as the case may be, shall pay all reasonable fees and expenses of such counsel promptly as statements therefor are received; provided, that the CORPDAL:59869.4 22768-00022 48 <PAGE> Indemnified Parties and the Company, VTEL or the Surviving Corporation, as the case may be, will use their respective best efforts to assist in the vigorous defense of any such matter; provided, further, that neither the Company, VTEL nor the Surviving Corporation shall be liable for any settlement effected without their written consent, which consent, if the Company, VTEL or the Surviving Corporation fails to assume the defense of any such matter, shall not be unreasonably withheld and in no event shall be withheld in bad faith; and provided, further, that neither the Company, VTEL nor the Surviving Corporation shall have any obligation hereunder to any Indemnified Party when and if a court of competent jurisdiction shall ultimately determine, after exhaustion of all avenues of appeal, that such Indemnified Party is not entitled to indemnification hereunder (at which point such Indemnified Party shall promptly refund, without interest, to the indemnifying party all amounts previously paid by the indemnifying party hereunder). Any Indemnified Party wishing to claim indemnification under this Section 6.14, upon learning of any such claim, action, suit, proceeding or investigation, shall promptly notify the indemnifying party thereof. In the event the Indemnified Parties are entitled to separate counsel pursuant to this paragraph (a), the Indemnified Parties may as a group retain only one such law firm to represent them with respect to any such matter unless there is, under applicable standards of professional conduct, a conflict on any significant issue between the positions of any two or more Indemnified Parties in which case the Indemnified Parties may retain, at the expense of the Company, VTEL or the Surviving Corporation, as the case may be, two additional law firms.

(d) This Section shall survive the closing of the transactions contemplated hereby, is intended to benefit the Company, VTEL, the Surviving Corporation and each of the Indemnified Parties (each of whom shall be entitled to enforce this Section against the Company or the Surviving Corporation, as the case may be) and shall be binding on all successors and assigns of the Surviving Corporation. The exercise by any person of such person's rights under any of paragraphs (a), (b) or (c) of this Section shall not preclude the exercise of such person's rights under any such other paragraph of this section, provided that such party shall not be entitled to multiple recoveries thereunder. (e) For six years from the Effective Time, VTEL shall cause the Surviving Corporation to provide to the Company's current directors and officers liability insurance protection of the same kind and scope as that provided by the Company's directors' and CORPDAL:59869.4 22768-00022 49 <PAGE> officers' liability insurance policies (copies of which have been made available to VTEL) in effect on the date hereof; provided, however, that in no event shall the Surviving Corporation be required to expend in any one year an amount in excess of 150% of the annual premiums currently paid by the Company for such insurance; and, provided, further, that if the annual premiums of such insurance coverage exceeds such amount, the Surviving Corporation shall be obligated to obtain a policy with the greatest coverage available for a cost not exceeding such amount. (f) In the event the Surviving Corporation, VTEL or any of their respective successors or assigns (i) consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) transfers all or substantially all of its properties and assets to any person, then, and in each such case, proper provision shall be made so that the successors and assigns of the Surviving Corporation or VTEL, as the case may be, assume the obligations set forth in this Section 6.14.

VTEL will further supply such person with any information in its possession which he may reasonably request in connection with any such proposed sale. (c) If any of the certificates representing any VTEL Common Stock acquired in the Merger is presented to VTEL's transfer agent for registration of transfer in connection with any sale theretofore made under paragraph (d) of Rule 145, provided such certificate is duly endorsed for transfer or accompanied by a duly executed stock power and is accompanied by an opinion of counsel satisfactory to VTEL that such transfer has complied with the requirements of Rule 145, VTEL will promptly instruct its transfer agent to register such transfer and to issue one or more new certificates free of any stop transfer order or restrictive legend.

(d) Issuer shall notify Grantee promptly in writing of the occurrence of any Initial Triggering Event or Subsequent Triggering Event of which it has notice (together, a "Triggering Event"), it being understood that the giving of such notice by Issuer shall not be a condition to the right of the Holder to exercise the Option.

(f) At the closing referred to in subsection (e) of this Section 2, the Holder shall pay to Issuer the aggregate purchase price for the shares of Common Stock purchased pursuant to the exercise of the Option in immediately available funds by wire transfer to a bank account designated by Issuer, provided that failure or refusal of Issuer to designate such a bank account shall not preclude the Holder from exercising the Option. (g) At such closing, simultaneously with the delivery of immediately available funds as provided in subsection (f) of this Section 2, Issuer shall deliver to the Holder a certificate or certificates representing the number of shares of Common Stock purchased by the Holder and, if the Option should be exercised in part only, a new Option evidencing the rights of the Holder thereof to purchase the balance of the shares purchasable hereunder, and the Holder shall deliver to Issuer a copy of this Agreement and a letter agreeing that the Holder will not offer to sell or otherwise dispose of such shares in violation of applicable law or the provisions of this Agreement. (h) Certificates for Common Stock delivered at a closing hereunder may be endorsed with a restrictive legend that shall read substantially as follows: "The transfer of the shares represented by this certificate is subject to certain provisions of an agreement between the registered holder hereof and Issuer and to resale restrictions arising under the Securities Act of 1933, as amended. A copy of such agreement is on file at the principal office of Issuer and will be provided to the holder hereof without charge upon receipt by Issuer of a written request therefor." It is understood and agreed that: (i) the reference to the resale restrictions of the Securities Act of 1933, as amended (the "1933 Act"), in the above legend shall be removed by delivery of substitute certificates) without such reference if the Holder shall have delivered to Issuer a copy of a letter from the staff of the SEC, or an opinion of counsel, in form and substance reasonably satisfactory to Issuer, to the effect that such legend is not required for purposes of the 1933 Act; (ii) the reference to the provisions to this Agreement in the above legend shall be removed by delivery of substitute certificate(s) without such reference if the shares have been sold or transferred in compliance with the provisions of this Agreement and under circumstances that do not require the retention of such reference; and (iii) the legend shall be removed in its entirety if the conditions in the preceding clauses (i) and (ii) are both satisfied. In addition, such certificates shall bear any other legend as may be required by law. (i) Upon the giving by the Holder to Issuer of the written notice of exercise of the Option provided for under subsection (e) of this Section 2 and the tender of the applicable purchase price in immediately available funds, the Holder shall be deemed to be the holder of CORPDAL:59868.4 22768-00022 4 <PAGE> record of the shares of Common Stock issuable upon such exercise, notwithstanding that the stock transfer books of Issuer shall then be closed or that certificates representing such shares of Common Stock shall not then be actually delivered to the Holder. Issuer shall pay all expenses, and any and all United States federal, state and local taxes and other charges that may be payable in connection with the preparation, issue and delivery of stock certificates under this Section 2 in the name of the Holder or its assignee, transferee or designee. 3. Issuer agrees: (i) that it shall at all times maintain, free from preemptive rights, sufficient authorized but unissued or treasury shares of Common Stock so that the Option may be exercised without additional authorization of Common Stock after giving effect to all other options, warrants, convertible securities and other rights to purchase Common Stock; (ii) that it will not, by charter amendment or through reorganization, consolidation, merger, dissolution or sale of assets, or by any other voluntary act, avoid or seek to avoid the observance or performance of any of the covenants, stipulations or conditions to be observed or performed hereunder by Issuer; (iii) promptly to take all action as may from time to time be required (including complying with all premerger notification, reporting and waiting period requirements specified in 15 U.S.C. ss.18a and regulations promulgated thereunder) in order to permit the Holder to exercise the Option and Issuer duly and effectively to issue shares of Common Stock pursuant hereto; and (iv) promptly to take all action provided herein to protect the rights of the Holder against dilution. 4. This Agreement (and the Option granted hereby) are exchangeable, without expense, at the option of the Holder, upon presentation and surrender of this Agreement at the principal office of Issuer, for other Agreements providing for Options of different denominations entitling the holder thereof to purchase, on the same terms and subject to the same conditions as are set forth herein, in the aggregate the same number of shares of Common Stock purchasable hereunder. The terms "Agreement" and "Option" as used herein include any Stock Option Agreements and related Options for which this Agreement (and the Option granted hereby) may be exchanged. Upon receipt by Issuer of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Agreement, and (in the case of loss, theft or destruction) of reasonably satisfactory indemnification, and upon surrender and cancellation of this Agreement, if mutilated, Issuer will execute and deliver a new Agreement of like tenor and date. Any such new Agreement executed and delivered shall constitute an additional contractual obligation on the part of Issuer, whether or not the Agreement so lost, stolen, destroyed or mutilated shall at any time be enforceable by anyone. 5. In addition to the adjustment in the number of shares of Common Stock that are purchasable upon exercise of the Option pursuant to Section 1 of this Agreement, the number of shares of Common Stock purchasable upon the exercise of the Option and the Option Price shall be subject to adjustment from time to time as provided in this Section 5. In the event of any change in, or distributions in respect of, the Common Stock by reason of stock dividends, split-ups, mergers, recapitalizations, combinations, subdivisions, conversions, exchanges of shares, distributions on or in respect of the Common Stock that would be prohibited under the terms of the Merger Agreement, or the like, the type and number of shares of Common Stock purchasable upon exercise hereof and the Option Price shall be appropriately adjusted in such manner as shall fully preserve the economic benefits provided hereunder and proper provision shall be made in CORPDAL:59868.4 22768-00022 5 <PAGE> any agreement governing any such transaction to provide for such proper adjustment and the full satisfaction of the Issuer's obligations hereunder. 6. Upon the occurrence of a Subsequent Triggering Event that occurs prior to an Exercise Termination Event, Issuer shall, at the request of Grantee delivered within 90 days of such Subsequent Triggering Event (whether on its own behalf or on behalf of any subsequent holder of this Option (or part thereof) or any of the shares of Common Stock issued pursuant hereto), promptly prepare, file and keep current a shelf registration statement under the 1933 Act covering this Option and any shares issued and issuable pursuant to this Option and shall use its reasonable best efforts to cause such registration statement to become effective and remain current in order to permit the sale or other disposition of this Option and any shares of Common Stock issued upon total or partial exercise of this Option ("Option Shares") in accordance with any plan of disposition requested by Grantee. Issuer will use its reasonable best efforts to cause such registration statement first to become effective and then to remain effective for such period not in excess of 180 days from the day such registration statement first becomes effective or such shorter time as may be reasonably necessary to effect such sales or other dispositions. Grantee shall have the right to demand two such registrations. The foregoing notwithstanding, if, at the time of any request by Grantee for registration of the Option or Option Shares as provided above, Issuer is in registration with respect to an underwritten public offering of shares of Common Stock, and if in the good faith judgment of the managing underwriter or managing underwriters, or, if none, the sole underwriter or underwriters, of such offering the inclusion of the Holder's Option or Option Shares would interfere with the successful marketing of the shares of Common Stock offered by Issuer, the number of Option Shares otherwise to be covered in the registration statement contemplated hereby may be reduced; and provided, however, that after any such required reduction the number of Option Shares to be included in such offering for the account of the Holder shall constitute at least 25% of the total number of shares to be sold by the Holder and Issuer in the aggregate; and provided further, however, that if such reduction occurs, then the Issuer shall file a registration statement for the balance as promptly as practical and no reduction shall thereafter occur. Each such Holder shall provide all information reasonably requested by Issuer for inclusion in any registration statement to be filed hereunder. If requested by any such Holder in connection with such registration, Issuer shall become a party to any underwriting agreement relating to the sale of such shares, but only to the extent of obligating itself in respect of representations, warranties, indemnities and other agreements customarily included in secondary offering underwriting agreements for the Issuer. Upon receiving any request under this Section 6 from any Holder, Issuer agrees to send a copy thereof to any other person known to Issuer to be entitled to registration rights under this Section 6, in each case by promptly mailing the same, postage prepaid, to the address of record of the persons entitled to receive such copies. Notwithstanding anything to the contrary contained herein, in no event shall Issuer be obligated to effect more than two registrations pursuant to this Section 6 by reason of the fact that there shall be more than one Grantee as a result of any assignment or division of this Agreement. 7. (a) Immediately prior to the occurrence of a Repurchase Event (as defined below), (i) following a request of the Holder, delivered prior to an Exercise Termination Event (or such later period as provided in Section 10), Issuer (or any successor thereto) shall repurchase the Option from the Holder at a price (the "Option Repurchase Price") equal to the amount by which CORPDAL:59868.4 22768-00022 6 <PAGE> (A) the Market/Offer Price (as defined below) exceeds (B) the Option Price, multiplied by the number of shares for which this Option may then be exercised and (ii) at the request of the owner of Option Shares from time to time (the "Owner"), delivered within 90 days of such occurrence (or such later period as provided in Section 10), Issuer shall repurchase such number of the Option Shares from the Owner as the owner shall designate at a price (the "Option Share Repurchase Price") equal to the Market/Offer Price multiplied by the number of Option Shares so designated. The term "Market/Offer Price" shall mean the highest of (i) the price per share of Common Stock at which a tender offer or exchange offer therefor has been made, (ii) the price per share of Common Stock to be paid by any third party pursuant to an agreement with Issuer entered into subsequent to the date hereof, (iii) the highest closing price for shares of Common Stock within the six-month period immediately preceding the date the Holder gives notice of the required repurchase of this Option or the Owner gives notice of the required repurchase of Option Shares, as the case may be, or (iv) in the event of a sale of all or a substantial portion of Issuer's assets, the sum of the price paid in such sale for such assets and the current market value of the remaining assets of Issuer as determined by a nationally recognized investment banking firm mutually selected by the Holder or the Owner, as the case may be, on the one hand, and the Issuer, on the other, divided by the number of shares of Common Stock of Issuer outstanding at the time of such sale. In determining the Market/Offer Price, the value of consideration other than cash shall be determined by a nationally recognized investment banking firm mutually selected by the Holder or Owner, as the case may be, on the one hand, and the Issuer, on the other. (b) The Holder and the Owner, as the case may be, may exercise its right to require Issuer to repurchase the Option and any Option Shares pursuant to this Section 7 by surrendering for such purpose to Issuer, at its principal office, a copy of this Agreement or certificates for Option Shares, as applicable, accompanied by a written notice or notices stating that the Holder or the Owner, as the case may be, elects to require Issuer to repurchase this Option and/or the Option Shares in accordance with the provisions of this Section 7. Within the latter to occur of (x) five business days after the surrender of the Option and/or certificates representing Option Shares and the receipt of such notice or notices relating thereto and (y) the time that is immediately prior to the occurrence of a Repurchase Event, Issuer shall deliver or cause to be delivered to the Holder the Option Repurchase Price and/or to the Owner the Option Share Repurchase Price therefor or the portion thereof that issuer is not then prohibited under applicable law and regulation from so delivering. (c) To the extent that Issuer is prohibited under applicable law or regulation from repurchasing the Option and/or the Option Shares in full, Issuer shall immediately so notify the Holder and/or the Owner and thereafter deliver or cause to be delivered, from time to time, to the Holder and/or the Owner, as appropriate, the portion of the Option Repurchase Price and the Option Share Repurchase Price, respectively, that it is no longer prohibited from delivering, within five business days after the date on which Issuer is no longer so prohibited; provided, however, that if Issuer at any time after delivery of a notice of repurchase pursuant to paragraph (b) of this Section 7 is prohibited under applicable law or regulation from delivering to the Holder and/or the Owner, as appropriate, the Option Repurchase Price and the Option Share Repurchase Price, respectively, in full (and Issuer hereby undertakes to use its best efforts to obtain all required regulatory and legal approvals and to file any required notices as promptly as practicable CORPDAL:59868.4 22768-00022 7 <PAGE> in order to accomplish such repurchase), the Holder or Owner may revoke its notice of repurchase of the Option or the Option Shares either in whole or to the extent of the prohibition, whereupon, in the latter case, Issuer shall promptly (i) deliver to the Holder and/or the Owner, as appropriate, that portion of the Option Repurchase Price or the Option Share Repurchase Price that Issuer is not prohibited from delivering; and (ii) deliver, as appropriate, either (A) to the Holder, a new Stock Option Agreement evidencing the right of the Holder to purchase that number of shares of Common Stock obtained by multiplying the number of shares of Common Stock for which the surrendered Stock Option Agreement was exercisable at the time of delivery of the notice of repurchase by a fraction, the numerator of which is the Option Repurchase Price less the portion thereof theretofore delivered to the Holder and the denominator of which is the Option Repurchase Price, or (B) to the Owner, a certificate for the Option Shares it is then so prohibited from repurchasing. (d) For purposes of this Section 7, a Repurchase Event shall be deemed to have occurred (i) upon the consummation of any merger, consolidation or similar transaction involving Issuer or any purchase, lease or other acquisition of all or a substantial portion of the assets of Issuer or (ii) upon the acquisition by any person of beneficial ownership of 50% or more of the then outstanding shares of Common Stock, provided that no such event shall constitute a Repurchase Event unless a Subsequent Triggering Event shall have occurred prior to an Exercise Termination Event. The parties hereto agree that Issuer's obligations to repurchase the Option or Option Shares under this Section 7 shall not terminate upon the occurrence of an Exercise Termination Event unless no Subsequent Triggering Event shall have occurred prior to the occurrence of an Exercise Termination Event. 8. (a) In the event that prior to an Exercise Termination Event, Issuer shall enter into an agreement (i) to consolidate with or merge into any person, other than Grantee or one of its Subsidiaries, and shall not be the continuing or surviving corporation of such consolidation or merger, (ii) to permit any person, other than Grantee or one of its Subsidiaries, to merge into Issuer and Issuer shall be the continuing or surviving corporation, but, in with such merger, the then outstanding shares of Common Stock shall into or exchanged for stock or other securities of any other person any other property or the then outstanding shares of Common Stock shall after such merger represent less than 50% of the outstanding voting shares and voting share equivalents of the merged company, or (iii) to sell or otherwise transfer all or substantially all of its assets to any person, other than Grantee or one of its Subsidiaries, then, and in each such case, the agreement governing such transaction shall make proper provision so that the Option shall, upon the consummation of any such transaction and upon the terms and conditions set forth herein, be converted into, or exchanged for, an Option (the "Substitute Option"), at the election of the Holder, of either (x) the Acquiring Corporation (as hereinafter defined) or (y) any person that controls the Acquiring Corporation. (b) The following terms have the meanings indicated: (1) "Acquiring Corporation" shall mean (i) the continuing or surviving corporation of a consolidation or merger with Issuer (if other than Issuer), (ii) Issuer in a merger CORPDAL:59868.4 22768-00022 8 <PAGE> in which Issuer is the continuing or surviving person, and (iii) the transferee of all or substantially all of Issuer's assets. (2) "Substitute Common Stock" shall mean the common stock issued by the issuer of the Substitute Option upon exercise of the Substitute Option. (3) "Assigned Value" shall mean the Market/Offer Price, as defined in Section 7. (4) "Average Price" shall mean the average closing price of a share of the Substitute Common Stock for the one year immediately preceding the consolidation, merger or sale in question, but in no event higher than the closing price of the shares of Substitute Common Stock on the day preceding such consolidation, merger or sale; provided that if Issuer is the issuer of the Substitute Option, the Average Price shall be computed with respect to a share of common stock issued by the person merging into Issuer or by any company which controls or is controlled by such person, as the Holder may elect. (c) The Substitute Option shall have the same terms as the Option, provided, that if the terms of the Substitute Option cannot, for legal reasons, be the same as the Option, such terms shall be as similar as possible and in no event less advantageous to the Holder. The issuer of the Substitute Option shall also enter into an agreement with the then Holder or Holders of the Substitute Option in substantially the same form as this Agreement, which shall be applicable to the Substitute Option. (d) The Substitute Option shall be exercisable for such number of shares of Substitute Common Stock as is equal to the Assigned Value multiplied by the number of shares of Common Stock for which the Option is then exercisable, divided by the Average Price. The exercise price of the Substitute Option per share of Substitute Common Stock shall then be equal to the Option Price multiplied by a fraction, the numerator of which shall be the number of shares of Common Stock for which the Option is then exercisable and the denominator of which shall be the number of shares of Substitute Common Stock for which the Substitute Option is exercisable. (e) In no event, pursuant to any of the foregoing paragraphs, shall the Substitute Option be exercisable for more than 19.9% of the shares of Substitute Common Stock outstanding prior to exercise of the Substitute Option. In the event that the Substitute Option would be exercisable for more than 19.9% of the shares of Substitute Common Stock outstanding prior to exercise but for this clause (e), the issuer of the Substitute Option (the "Substitute Option Issuer") shall make a cash payment to Holder equal to the excess of (i) the value of the Substitute Option without giving effect to the limitation in this clause (e) over (ii) the value of the Substitute Option after giving effect to the limitation in this clause (e). This difference in value shall be determined by a nationally recognized investment banking firm selected by the Holder or the Owner, as the case may be, and reasonably acceptable to the Acquiring Corporation. CORPDAL:59868.4 22768-00022 9 <PAGE> (f) Issuer shall not enter into any transaction described in subsection (a) of this Section 8 unless the Acquiring Corporation and any person that controls the Acquiring Corporation assume in writing all the obligations of Issuer hereunder. 9. (a) At the request of the holder of the Substitute Option (the "Substitute Option Holder"), the Substitute Option Issuer shall repurchase the Substitute Option from the Substitute Option Holder at a price (the "Substitute Option Repurchase Price") equal to (x) the amount by which (i) the Highest Closing Price (as hereinafter defined) exceeds (ii) the exercise price of the Substitute Option, multiplied by the number of shares of Substitute Common Stock for which the Substitute Option may then be exercised plus (y) Grantee's reasonable out-of-pocket expenses (to the extent not previously reimbursed), and at the request of the owner (the "Substitute Share Owner") of shares of Substitute Common Stock (the "Substitute Shares"), the Substitute Option Issuer shall repurchase the Substitute Shares at a price (the "Substitute Share Repurchase Price") equal to (x) the Highest Closing Price multiplied by the number of Substitute Shares so designated plus (y) Grantee's reasonable out-of-pocket expenses (to the extent not previously reimbursed). The term "Highest Closing Price" shall mean the highest closing price for shares of Substitute Common Stock within the six-month period immediately preceding the date the Substitute Option Holder gives notice of the required repurchase of the Substitute Option or the Substitute Share Owner gives notice of the required repurchase of the Substitute Shares, as applicable. (b) The Substitute Option Holder and the Substitute Share Owner, as the case may be, may exercise its respective right to require the Substitute Option Issuer to repurchase the Substitute Option and the Substitute Shares pursuant to this Section 9 by surrendering for such purpose to the Substitute Option Issuer, at its principal office, the agreement for such Substitute Option (or, in the absence of such an agreement, a copy of this Agreement) and certificates for Substitute Shares accompanied by a written notice or notices stating that the Substitute Option Holder or the Substitute Share Owner, as the case may be, elects to require the Substitute Option Issuer to repurchase the Substitute Option and/or the Substitute Shares in accordance with the provisions of this Section 9. As promptly as practicable, and in any event within five business days after the surrender of the Substitute Option and/or certificates representing Substitute Shares and the receipt of such notice or notices relating thereto, the Substitute Option Issuer shall deliver or cause to be delivered to the Substitute Option Holder the Substitute Option Repurchase Price and/or to the Substitute Share Owner the Substitute Share Repurchase Price therefor or, in either case, the portion thereof which the Substitute Option Issuer is not then prohibited under applicable law and regulation from so delivering. (c) To the extent that the Substitute Option Issuer is prohibited under applicable law or regulation from repurchasing the Substitute Option and/or the Substitute Shares in part or in full, the Substitute Option Issuer following a request for repurchase pursuant to this Section 9 shall immediately so notify the Substitute Option Holder and/or the Substitute Share Owner and thereafter deliver or cause to be delivered, from time to time, to the Substitute Option Holder and/or the Substitute Share Owner, as appropriate, the portion of the Substitute Share Repurchase Price, respectively, which it is no longer prohibited from delivering, within five business days after the date on which the Substitute Option Issuer is no longer so prohibited; provided, however, that if the Substitute Option Issuer is at any time after delivery of a notice of repurchase pursuant CORPDAL:59868.4 22768-00022 10 <PAGE> to subsection (b) of this Section 9 prohibited under applicable law or regulation from delivering to the Substitute Option Holder and/or the Substitute Share Owner, as appropriate, the Substitute Option Repurchase Price and the Substitute Share Repurchase Price, respectively, in full (and the Substitute Option Issuer shall use its best efforts to receive all required regulatory and legal approvals as promptly as practicable in order to accomplish such repurchase), the Substitute Option Holder or Substitute Share Owner may revoke its notice of repurchase of the Substitute Option or the Substitute Shares either in whole or to the extent of the prohibition, whereupon, in the latter case, the Substitute Option Issuer shall promptly (i) deliver to the Substitute Option Holder or Substitute Share Owner, as appropriate, that portion of the Substitute Option Repurchase Price or the Substitute Share Repurchase Price that the Substitute Option Issuer is not prohibited from delivering; and (ii) deliver, as appropriate, either (A) to the Substitute Option Holder, a new Substitute Option evidencing the right of the Substitute Option Holder to purchase that number of shares of the Substitute Common Stock obtained by multiplying the number of shares of the Substitute Common Stock for which the surrendered Substitute Option was exercisable at the time of delivery of the notice of repurchase by a fraction, the numerator of which is the Substitute Option Repurchase Price less the portion thereof theretofore delivered to the Substitute Option Holder and the denominator of which is the Substitute Option Repurchase Price, or (B) to the Substitute Share Owner, a certificate for the Substitute Common Shares it is then so prohibited from repurchasing. 10. The 90-day period for exercise of certain rights under Sections 2, 6, 7, 9 and 13 shall be extended: (i) to the extent necessary to obtain all regulatory approvals for the exercise of such rights, and for the expiration of all statutory waiting periods; and (ii) to the extent necessary to avoid liability under Section 16(b) of the 1934 Act by reason of such exercise. 11. Issuer hereby represents and warrants to Grantee as follows: (a) Issuer has full corporate power and authority to execute and deliver this Agreement and to consummate the transactions contemplated hereby. The execution and delivery of this Agreement and the consummation of the transactions contemplated hereby have been duly and validly authorized by the Board of Directors of Issuer and no other corporate proceedings on the part of Issuer are necessary to authorize this Agreement or to consummate the transactions so contemplated. This Agreement has been duly and validly executed and delivered by Issuer, and constitutes a legal and binding agreement, enforceable against Issuer in accordance with its terms. (b) Issuer has taken all necessary corporate action to authorize and reserve and to permit it to issue, and at all times from the date hereof through the termination of this Agreement in accordance with its terms will have reserved for issuance upon the exercise of the Option, that number of shares of Common Stock equal to the maximum number of shares of Common Stock at any time and from time to time issuable hereunder, and all such shares, upon issuance pursuant hereto, will be duly authorized, validly issued, fully paid, nonassessable, and will be delivered free and clear of all claims, liens, encumbrance and security interests and not subject to any preemptive rights. 12. Grantee hereby represents and warrants to Issuer that: CORPDAL:59868.4 22768-00022 11 <PAGE> (a) Grantee has all requisite corporate power and authority to enter into this Agreement and, subject to any approvals or consents referred to herein, to consummate the transactions contemplated hereby. The execution and delivery of this Agreement and the consummation of the transactions contemplated hereby have been duly authorized by all necessary corporate action on the part of Grantee. This Agreement has been duly executed and delivered by Grantee, and constitutes a legal and binding agreement, enforceable against Grantee in accordance with its terms. (b) The Option is not being, and any shares of Common Stock or other securities acquired by Grantee upon exercise of the Option will not be, acquired with a view to the public distribution thereof and will not be transferred or otherwise disposed of except in a transaction registered or exempt from registration under the Securities Act. 13. Neither of the parties hereto may assign any of its rights or obligations under this Option Agreement or the Option created hereunder to any other person, without the express written consent of the other party, except that in the event a Subsequent Triggering Event shall have occurred prior to an Exercise Termination Event, Grantee, subject to the express provisions hereof, may assign in whole or in part its rights and obligations hereunder within 90 days following such Subsequent Triggering Event (or such later period as provided in Section 10). 14. Each of Grantee and Issuer will use its best efforts to make all filings with, and to obtain consents of, all third parties and governmental authorities necessary to the consummation of the transactions contemplated by this Agreement, including without limitation making application to list the shares of Common Stock issuable hereunder on the Nasdaq Stock Market upon official notice of issuance. 15. The parties hereto acknowledge that damages would be an inadequate remedy for a breach of this Agreement by either party hereto and that the obligations of the parties hereto shall be enforceable by either party hereto through injunctive or other equitable relief. 16. If any term, provision, covenant or restriction contained in this Agreement is held by a court or a federal or state regulatory agency of competent jurisdiction to be invalid, void or unenforceable, the remainder of the terms, provisions and covenants and restrictions contained in this Agreement shall remain in full force and effect, and shall in no way be affected, impaired or invalidated. If for any reason such court or regulatory agency determines that the Holder is not permitted to acquire, or Issuer is not permitted to repurchase pursuant to Section 7, the full number of shares of Common Stock provided in Section l(a) hereof (as adjusted pursuant to Section l(b) or 5 hereof), it is the express intention of Issuer to allow the Holder to acquire or to require Issuer to repurchase such lesser number of shares as may be permissible, without any amendment or modification hereof. 17. All notices, requests, claims, demands and other communications hereunder shall be deemed to have been duly given when delivered in person, by cable, telegram, telecopy or telex, or by registered or certified mail (postage prepaid, return receipt requested) at the respective addresses of the parties set forth in the Merger Agreement.

Except as otherwise expressly provided herein, each of the parties hereto shall bear and pay all costs and expenses incurred by it or on its behalf in connection with the transactions contemplated hereunder, including fees and expenses of its own financial consultants, investment bankers, accountants and counsel. 21. Except as otherwise expressly provided herein or in the Merger Agreement, this Agreement contains the entire agreement between the parties with respect to the transactions contemplated hereunder and supersedes all prior arrangements or understandings with respect thereof, written or oral.
