Any securities to be delivered to the Company or its shareholders shall be valued as follows: (A) If then listed or admitted to trading on any national securities exchange or traded on any national market system, the value of the securities shall be the average of the daily closing prices for the thirty (30) trading days ending five (5) business days before the closing of the transaction, excluding any trades which are not bona fide, arm's length transactions.

If any event occurs as to which the other --------------------- provisions of this Article IV are not strictly applicable but the failure to make any adjustment would not fairly protect the purchase rights represented by this Warrant in accordance with the essential intent and principles hereof, then, in each such case, the Board of Directors of the Company shall determine in good faith the adjustments, if any, on a basis consistent with the essential intent and principles established in this Article IV, necessary to preserve, without dilution, the purchase rights represented by this Warrant. Upon such determination, the Company shall promptly make such adjustments and notify the Holder thereof. 4.9 Amendment of Articles of Incorporation. So long as the Warrant is -------------------------------------- outstanding and no shares of Series B Preferred Stock are issued and outstanding and the Series B Preferred Stock has not been converted into Common Stock in connection with a Registration, the Company shall not amend, or otherwise take any action that would affect, Article III, Section (d) of the Articles of Incorporation, without the prior written consent of the Holders of majority in interest under this Warrant, given in their sole discretion. If the Articles of Incorporation are amended in violation of this Section 4.9, then the provisions of this Article IV shall be adjusted so that the Holder shall receive with respect to the shares of Common Stock received upon conversion of the shares of Series B Preferred Stock obtained upon exercise of this Warrant thereafter, what would have been received had the Articles of Incorporation not been so amended, open payment of the same amount as would have been required had the Articles of Incorporation not been so amended. 4.10 Certificates and Notices. ------------------------ (a) Adjustment Certificates. Upon any adjustment of the Exercise ----------------------- Price and/or the number of shares of Series B Preferred Stock purchasable upon exercise of this -13- Warrant, a certificate, signed by (i) the Company's President or Chief Financial Officer, or (ii) any independent firm of certified public accountants of recognized national standing the Company selects at its own expense, setting forth in reasonable detail the events requiring the adjustment and the method by which such adjustment was calculated, shall be mailed to the Holder and shall specify the adjusted Exercise Price and the number of shares of Series B Preferred Stock purchasable upon exercise of the Warrant after giving effect to the adjustment. (b) Extraordinary Corporate Events. If the Company, after the date ------------------------------ hereof, proposes to effect (i) any transaction described in Sections 4.2 or 4.4 hereof, (ii) a liquidation, dissolution or winding up of the Company described in Section 4.6 hereof, or (iii) any payment of a dividend or distribution with respect to Series B Preferred Stock or Common Stock, then, in each such case, the Company shall mail to the Holder a notice describing such proposed action and specifying the date on which the Company's books shall close, or a record shall be taken, for determining the holders of Series B Preferred Stock or Common Stock, as appropriate, entitled to participate in such action, or the date on which such reorganization, reclassification, consolidation, merger, sale, transfer, Liquidation, dissolution or winding up shall take place or commence, as the case may be, and the date as of which it is expected that holders of Series B Preferred Stock and Common Stock of record shall be entitled to receive securities and/or other property deliverable upon such action, if any such date is to be fixed. Such notice shall be mailed to the Holder at least fifteen (15) days prior to the record date for such action in the case of any action described in clause (i) or clause (iii) above, and in the case of any action described in clause (ii) above, at least fifteen (15) days prior to the date on which the action described is to take place and at least fifteen (15) days prior to the record date for determining holders of Series B Preferred Stock or Common Stock, as appropriate, entitled to receive securities and/or other property in connection with such action. 4.11 No Impairment. The Company shall not, by amendment of the Articles ------------- of Incorporation or through any reorganization, recapitalization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company, but shall at all times in good faith assist in the carrying out of all the provisions of this Article IV and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the Holder against impairment. 4.12 Application.

EXHIBIT "B" ----------- INVESTMENT REPRESENTATION CERTIFICATE ------------------------------------- Purchaser: Company: Latitude Communications, Inc. Security: Series B Preferred Stock Amount: Date: In connection with the purchase of the above-listed securities (the "Securities"), the undersigned (the "Purchaser") represents to the Company as - ----------- --------- follows: (a) The Purchaser is aware of the Company's business affairs and financial condition, and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Securities. The Purchaser is purchasing the Securities for its own account for investment purposes only and not with a view to, or for the resale in connection with, any "distribution" thereof for purposes of the Securities Act of 1933, as amended (the "Securities ---------- Act"); - --- (b) The Purchaser understands that the Securities have not been registered under the Securities Act in reliance upon a specific exemption therefor, which exemption depends upon, among other things, the bona fide nature of the Purchaser's investment intent as expressed herein. In this connection, the Purchaser understands that, In the view of the Securities and Exchange Commission ("SEC"), the statutory basis for such exemption may be unavailable if --- the Purchaser's representation was predicated solely upon a present intention to hold these Securities for the minimum capital gains period specified under tax statutes, for a deterred sale, for or until an increase or decrease in the market price of the Securities, or for a period of one year or any other fixed period in the future; (c) The Purchaser further understands that the Securities must be held indefinitely unless subsequently registered under the Securities Act or unless an exemption from registration is otherwise available. Moreover, the Purchaser understands that the Company is under no obligation to register the Securities. In addition, the Purchaser understands that the certificate evidencing the Securities will be imprinted with the legend referred to in the Warrant under which the Securities are being purchased; (d) The Purchaser is aware of the provisions of Rule 144, promulgated under the Securities Act, which, in substance, permit limited public resale of "restricted securities" acquired, directly or indirectly, from the issuer thereof (or from an affiliate of such issuer), in a non-public offering subject to the satisfaction of certain conditions, if applicable, including, among other things: (i) the availability of certain public information about the Company; (ii) the resale occurring not less than two (2) years after the party has purchased and paid for the securities to be sold; (iii) the sale being made through a broker in an unsolicited "broker's transaction" or in transactions directly with a market maker (as said term is defined under the Securities Exchange Act of 1934) and the amount of securities being sold during any three-month period not exceeding the specified limitations stated therein; (e) The Purchaser further understands that at the time it wishes to sell the Securities there may be no public market upon which to make such a sale, and that, even if such a public market upon which to make such a sale then exists, the Company may not be satisfying the current public information requirements of Rule 144, and that, in such event, the Purchaser may be precluded from selling the Securities under Rule 144 even if the two-year minimum holding period had been satisfied; (f) The Purchaser further understands that in the event all of the requirements of Rule 144 are not satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding; the fact that Rule 144 is not exclusive, the staff of the SEC has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rule 144 will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk; and (g) The Purchaser is an "accredited investor" as defined in Regulation D as promulgated by the SEC.

(b) The Company will use its best efforts to effect promptly after the Notice Period the registration under the Securities Act of all shares of Registrable Stock specified in the requests of the Initiating Holders and the requests of the other Holders subject, however, to the limitations set forth in Section 2.4. 2.3 Registration Procedures. Whenever the Company is required by ----------------------- the provisions of this Section 2 to use its best efforts to effect promptly the registration of shares of Registrable Stock, the Company will: (a) prepare and file with the Commission a registration statement with respect to such shares and use its best efforts to cause such registration statement to become and remain effective as provided herein; (b) prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective and current and to comply with the provisions of the Securities Act with respect to the disposition of all shares covered by such registration statement, including such amendments and supplements as may be necessary to reflect the intended method of disposition from time to time of the prospective seller or sellers of such shares, but for no longer than one hundred twenty (120) days subsequent to the effective date of such registration in the case of a registration statement on Form S-1 or S-2 and for no longer than ninety (90) days in the case of a registration statement on Form S-3; (c) furnish to each prospective seller such number of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as such seller may reasonably request in order to facilitate the public sale or other disposition of the shares owned by such seller; (d) use its best efforts to register or qualify the shares covered by such registration statement under such other securities or blue sky or other applicable laws of such jurisdiction within the United States as each prospective seller shall reasonably request, to enable such seller to consummate the public sale or other disposition in such jurisdictions of the shares -3- owned by such seller; provided, however, that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not at the time so qualified or to take any action which would subject it to service of process in suits other than those arising out of the offer or sale of the Registrable Stock covered by such registration statement in any jurisdiction where it is not at the time so subject; and (e) furnish to each prospective seller, to the extent requested by such seller, a signed counterpart, addressed to the prospective sellers, of (i) an opinion of counsel for the Company, dated the closing date of the sale of the applicable Registrable Stock, and (ii) a "comfort" letter signed by the independent public accountants who have certified the Company's financial statements included in the registration statement, covering substantially the same matters with respect to the registration statement (and the prospectus included therein) and (in the case of the "comfort" letter) with respect to events subsequent to the date of the financial statements, as are customarily covered in opinions of issuer's counsel and in "comfort" letters delivered to the underwriters in underwritten public offerings of securities. 2.4 Limitations on Required Registrations. ------------------------------------- (a) The Company shall not be required to effect more than two registrations pursuant to Section 2.2. The Company shall not be required to effect any registration unless the anticipated aggregate offering price, net of underwriting discounts and commissions, would exceed $2,000,000. (b) The Company shall not be required to cause a registration requested pursuant to Section 2.2 to become effective prior to the earlier of (i) four years after the date of the first closing under the First Series A Purchase Agreement or (ii) six (6) months after the Company's initial registration with the Commission (other than a registration effected solely to implement an employee benefit plan or a transaction to which Rule 145 of the Commission is applicable). (c) The Company shall not register securities for sale for its own account or for the account of holders of securities other than Registrable Stock in any registration requested pursuant to Section 2.2 without the written consent of Initiating Holders who hold at least 51% of the Registrable Stock as to which registration has been requested, unless such securities are entitled to be included in such registration only to the extent that the inclusion of such securities will not diminish the amount of Registrable Stock included in such registration or otherwise materially and adversely affect the right of the Initiating Holders to have their Registrable Securities registered. The Company may not cause any other registration of securities for sale for its own account (other than a transaction to which Rule 145 of the Commission is applicable or a registration effected solely to implement an employee benefit plan) to be initiated after a registration requested pursuant to Section 2.2 and to become effective less than 90 days after the effective date of any registration requested pursuant to Section 2.2. (d) Whenever a requested registration is for an underwritten offering, only shares which are to be included in the underwriting may be included in the registration. Notwithstanding the provisions of Sections 2.2(b) and 2.4(c), if the underwriter determines that -4- (i) marketing factors require a limitation of the total number of shares to be underwritten, or (ii) the offering price per share would be reduced by the inclusion of the shares of the Company or others, then the number of shares to be included in the registration and underwriting shall first be allocated among all Holders who indicated to the Company their decision to distribute any of their Registrable Stock through such underwriting, in proportion, as nearly as practicable, to the respective numbers of shares of Registrable Stock owned by such Holders at the time of filing the registration statement, then, if any, to the Company and others. No stock excluded from the underwriting by reason of the underwriter's marketing limitation shall be included in such registration. If the Company disapproves of any such underwriting, the Company may elect to withdraw therefrom by written notice to the Initiating Holders and the underwriter. The securities so withdrawn from such underwriting shall also be withdrawn from such registration. (e) If at the time of any request to register Registrable Stock pursuant to Section 2.2 hereof, the Company is engaged, or has fixed plans to engage within 90 days of the time of the request, in a registered public offering as to which the Holders may include Registrable Stock pursuant to Section 2.5 hereof or the Company is engaged in any other activity which, in the good faith determination of the Board, would be adversely affected by the requested registration to the material detriment of the Company, then the Company may at its option direct that such request be delayed for a period not in excess of 120 days from the effective date of such offering, or the date of commencement of such other material activity, as the case may be, such right to delay a request to be exercised by the Company not more than once in any 12- month period while the rights set forth in Section 2.2 are in effect. 2.5 Incidental Registration. If the Company at any time proposes ----------------------- to register any of its Common Stock under the Securities Act (other than a registration effected solely to implement an employee benefit plan or a transaction to which Rule 145 of the Commission is applicable), it will each such time give written notice to all Holders of its intention so to do. Upon the written request of a Holder or Holders given within 20 days after receipt of any such notice (stating the number of shares of Registrable Stock to be disposed of by such Holder or Holders and the intended method of disposition), the Company will use its best efforts to cause all such shares intended to be disposed of, which the Holders shall have requested registration thereof, to be registered under the Securities Act so as to permit the disposition (in accordance with the methods in said request) by such Holder or Holders of the shares so registered, subject, however, to the limitations set forth in Section 2.6. 2.6 Limitations on Incidental Registration. If the registration -------------------------------------- of which the Company gives notice pursuant to Section 2.5 is for an underwritten offering, only securities which are to be included in the underwriting may be included in the registration. Notwithstanding any provision of Section 2.5, if the underwriter determines that marketing factors require a limitation of the number of shares to be underwritten, the underwriter may exclude or otherwise limit the number of shares, including Registrable Stock, requested to be included in the registration and underwriting to a number of shares not less than twenty percent (20%) of the aggregate number of shares to be disposed of in the registration and underwriting, unless the registration is for an initial public offering (in which case the percentage may be less). The Company shall so advise all Holders of any limitation (except those Holders who have not indicated to the -5- Company their decision to distribute any of their Registrable Stock through such underwriting), and the number of shares, including Registrable Stock, that may be included in the registration and underwriting shall be allocated among the selling shareholders in proportion, as nearly as practicable, to the respective amounts of securities, including Registrable Stock, owned by such Holders and other selling shareholders entitled to be included therein at the time of filing the registration statement, in accordance with Section 2.12(a). No Registrable Stock excluded from the underwriting by reason of the underwriter's marketing limitation shall be included in such registration. If any Holder disapproves of any such underwriting, such person may elect to withdraw therefrom by written notice to the Company and the underwriter. The Registrable Stock and/or other securities so withdrawn from such underwriting shall also be withdrawn from such registration. The registration rights granted under Sections 2.2, 2.5 and 2.8 shall terminate as to any Holder or permissible transferee or assignee of such rights if such person (a) holds one percent (1%) or less of the outstanding shares of Common Stock of the Company (on an as-converted basis) and (b) is permitted to sell all of the Registrable Stock held by him or her in a single transaction to the public pursuant to Rule 144. 2.7 Designation of Underwriter. -------------------------- (a) In the case of any registration effected pursuant to Section 2.2 or Section 2.8, a majority in interest of the requesting Holders shall have the right to designate the managing underwriter in any underwritten offering, which underwriter shall be reasonably acceptable to the Company. (b) In the case of any registration initiated by the Company, the Company shall have the right to designate the managing underwriter in any underwritten offering. 2.8 Form S-3. The Company shall register its Common Stock under -------- the Securities Exchange Act of 1934, as amended, as promptly as reasonably practicable following the effective date of the first registration of any securities of the Company on Form S-1 and the Company shall thereafter effect all qualifications and compliances as would permit or facilitate the sale and distribution of its stock on Form S-3, to the extent available. After the Company has qualified for the use of Form S-3, the Holders shall have the right to request an unlimited number of registrations on Form S-3 (such requests shall be in writing and shall state the number of shares of Registrable Stock to be disposed of and the intended method of disposition) except that the Company (a) shall not be required to effect more than one registration pursuant to this Section 2.8 in any six-month period, and (b) shall not be required to effect a registration pursuant to this Section 2.8 unless the Holder or Holders requesting registration hold an aggregate of at least thirty percent (30%) of the Registrable Stock then outstanding and propose to dispose of shares of Registrable Stock having an aggregate expected public offering price (before deduction of underwriting discounts and expenses of sale) of at least $500,000. The Company shall give notice to all Holders of the receipt of a request for registration pursuant to this Section 2.8 and shall provide a reasonable opportunity for other -6- Holders to participate in the registration, provided that if the registration is for an underwritten offering, the terms of Section 2.4(d) shall apply to all participants in such offering. Subject to the foregoing, the Company will use its best efforts to effect promptly the registration of all shares of Registrable Stock on Form S-3 to the extent requested by the Holder or Holders thereof. 2.9 Cooperation by Prospective Sellers. ---------------------------------- (a) Each prospective seller of Registrable Stock, and each underwriter designated by each such seller, will furnish to the Company such information as the Company may reasonably require from such seller or underwriter in connection with the registration statement (and the prospectus included therein). (b) Failure of a prospective seller of Registrable Stock to furnish the information and agreements described in this Section 2 shall not affect the obligations of the Company under this Section 2 to the remaining sellers who furnish such information and agreements unless, in the reasonable opinion of counsel to the Company or the underwriters, such failure impairs or may impair the viability of the offering or the legality of the registration statement or the underlying offering. (c) The Holders holding shares included in the registration statement will not (until further notice) effect sales thereof after receipt of telegraphic or written notice from the Company to suspend sales to permit the Company to correct or update a registration statement or prospectus but the obligations of the Company with respect to maintaining any registration statement current and effective shall be extended by a period of days equal to the period such suspension is in effect unless (i) such extension would result in the Company's inability to use the financial statements in the registration statement initially filed pursuant to the Holder or Holders' request and (ii) such correction or update did not result from the Company's acts or failures to act. At the end of the period during which the Company is obligated to keep the registration statement current and effective as described in Section 2.3(b) (and any extensions thereof required by the preceding sentence), the Holders holding shares included in the registration statement shall discontinue sales of shares pursuant to such registration statement upon receipt of notice from the Company of its intention to remove from registration the shares covered by such registration statement which remain unsold, and such Holders shall notify the Company of the number of shares registered which remain unsold immediately upon receipt of such notice from the Company. 2.10 Expenses of Registration. All expenses incurred in effecting ------------------------ any registration pursuant to this Section 2 including, without limitation, all registration and filing fees, printing expenses, expenses of compliance with blue sky laws, fees and disbursements of counsel for the Company and expenses of any audits incidental to or required by any such registration, shall be borne by the Company, except that (a) all expenses, fees and disbursements of any counsel retained by the Holders and all underwriting discounts and commissions shall be borne by the Holders holding the securities registered pursuant to such registration, according to the quantity of the securities so registered; (b) the Company shall not be required to pay for any -7- expenses of any registration proceeding begun pursuant to Section 2.2 if the registration request is subsequently withdrawn at the request of the Holders of a majority of the Registrable Securities to be registered (in which case all participating Holders shall bear such expenses), unless the Holders of a majority of the Registrable Securities agree to forfeit their right to one demand registration pursuant to Section 2.2, provided however, that if immediately prior to the time of such withdrawal, the Holders have learned of a materially adverse change in the condition, business or prospects of the Company from that known to the Holders at the time of their request, then the Holders shall not be required to pay any of such expenses and shall retain their rights pursuant to Section 2.2; and (c) the Company shall not be required to pay any expenses associated with any registration of Registrable Stock requested by Holders pursuant to Section 2.8. 2.11 Indemnification. --------------- (a) To the extent permitted by law, the Company will indemnify each Holder requesting or joining in a registration, each agent, officer and director of such Holders, each person controlling such Holder and each underwriter and selling broker of the securities so registered (collectively, "Indemnitees") against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any prospectus, offering circular or other document incident to any registration, qualification or compliance (or in any related registration statement, notification or the like) or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances in which they were made, or any violation by the Company of any rule or regulation promulgated under the Securities Act applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification or compliance, and will reimburse each such Indemnitee, promptly and on a current basis from time to time, for any legal and any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action, provided, however, that the Company will not be liable in -------- ------- any such case to the extent that any such claim, loss, damage or liability is caused by any untrue statement or omission so made in strict conformity with written information furnished to the Company by an instrument duly executed by such Indemnitees and stated to be specifically for use therein and except that the foregoing indemnity agreement is subject to the condition that, insofar as it relates to any such untrue statement (or alleged untrue statement) or omission (or alleged omission) made in the preliminary prospectus but eliminated or remedied in the amended prospectus on file with the Commission at the time the registration statement becomes effective or in the amended prospectus filed with the Commission pursuant to Rule 424(b) (the "Final Prospectus"), such indemnity agreement shall not inure to the benefit of any underwriter, or any Indemnitee if there is no underwriter, if a copy of the Final Prospectus was not furnished to the person or entity asserting the loss, liability, claim or damage at or prior to the time such furnishing is required by the Securities Act; provided, further, that this indemnity shall not be deemed to relieve any underwriter of any of its due diligence obligations; provided, further, that the indemnity agreement contained in this Section 2.11(a) shall not apply to amounts paid in settlement of any -8- such claim, loss, damage, liability or action if such settlement is effected without the consent of the Company, which consent shall not be unreasonably withheld. (b) To the extent permitted by law, each Holder requesting or joining in a registration and each underwriter of the securities so registered will indemnify the Company and its officers and directors and each other Holder and each person, if any, who controls any thereof within the meaning of Section 15 of the Securities Act and their respective successors against all claims, losses, damages and liabilities or actions in respect thereof arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any prospectus, offering circular or other document incident to any registration, qualification or compliance (or in any related registration statement, notification or the like) or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances in which they were made and will reimburse, promptly and on a current basis from time to time, the Company and each other person indemnified pursuant to this Section 2.11(b) for any legal and any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action, provided, however, that this Section 2.11(b) shall apply only if (and -------- ------- only to the extent that) such statement or omission was made in reliance upon and in strict conformity with written information (including, without limitation, written negative responses to inquiries) furnished to the Company by an instrument duly executed by such Holder or underwriter and stated to be specifically for use in such prospectus, offering circular or other document (or related registration statement, notification or the like) or any amendment or supplement thereto and except that the foregoing indemnity agreement is subject to the condition that, insofar as it relates to any such untrue statement (or alleged untrue statement) or omission (or alleged omission) made in the preliminary prospectus but eliminated or remedied in the amended Prospectus on file with the Commission at the time the registration statement becomes effective or in the Final Prospectus, such indemnity agreement by a Holder other than an underwriter shall not inure to the benefit of (i) the Company and (ii) any underwriter or any Holder, if there is no underwriter, if a copy of the Final Prospectus was not furnished to the person or entity asserting the loss, liability, claim or damage at or prior to the time such furnishing is required by the Securities Act; provided, further, that this indemnity shall not be -------- ------- deemed to relieve any underwriter of any of its due diligence obligations; provided, further, that the indemnity agreement contained in this Section - -------- ------- 2.11(b) shall not apply to amounts paid in settlement of any such claim, loss, damage, liability or action if such settlement is effected without the consent of the Holder or underwriter, as the case may be, which consent shall not be unreasonably withheld, and provided, further, that the obligations of such -------- ------- Holders shall be limited to an amount equal to the proceeds to each such Holder from the sale of Registrable Stock as contemplated herein, unless such claim, loss, damage, liability or action resulted from such Holder's fraudulent misconduct. -9- (c) Each party entitled to indemnification hereunder (the "Indemnified Party") shall give notice to the party required to provide indemnification (the "Indemnifying Party") promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party (at its expense) to assume the defense of any claim or any litigation resulting therefrom, provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be satisfactory to the Indemnified Party, and the Indemnified Party may participate in such defense at such party's expense, and provided, further, that -------- ------- the omission by any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section 2.11 except to the extent that the omission results in a failure of actual notice to the Indemnifying Party and such Indemnifying Party is damaged solely as a result of the failure to give notice. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. (d) The reimbursement required by this Section 2.11 shall be made by periodic payments during the course of the investigation or defense, as and when bills are received or expenses incurred. (e) The obligations under this Section 2.11 shall survive the redemption and conversion, if any, of the Series A Preferred Stock or Series B Preferred Stock, the completion of any offering of Registrable Stock in a registration statement under this Section 2, or otherwise. 2.12 Rights Which May Be Granted to Subsequent Investors. --------------------------------------------------- (a) Within the limitations prescribed by this Section 2.12(a), but not otherwise, the Company may grant to subsequent investors in the Company rights of incidental registration (such as those provided in Section 2.5). Such rights may only pertain to shares of Common Stock, including shares of Common Stock into which any other securities may be converted. Such rights may be granted with respect to (i) registrations actually requested by Initiating Holders pursuant to Section 2.2, but only in respect of that portion of any such registration as remains after inclusion of all Registrable Stock requested by Holders and (ii) registrations initiated by the Company, but only in respect of that portion of such registration as is available under the limitations set forth in Section 2.6 (which limitations shall apply to all Holders) and such rights shall be limited in all cases to sharing in the available portion of the registration in question with Holders, such sharing to be based on the number of shares of Common Stock held by the respective Holders and held by such other investors, plus the number of shares of Common Stock into which other securities held by the Holders and such other investors are convertible, which are entitled to registration rights. With respect to registrations which are for underwritten public offerings, "available portion" shall mean the portion of the underwritten shares which is available as specified in clauses (i) and (ii) of the third sentence of this Section 2.12(a). Shares not included in such underwriting shall not be registered. -10- (b) The Company may not grant to subsequent investors in the Company rights of registration upon request (such as those provided in Section 2.2) unless (i) such rights are limited to shares of Common Stock, (ii) all Holders are given enforceable contractual rights to participate in registrations requested by such subsequent investors (the right of priority of registration being pro rata as between subsequent investors and Holders), where such participation is on a pro rata basis between subsequent investors and Holders, (iii) subject to the limitations described in the final three sentences of Section 2.12(a), such rights shall not become effective prior to 90 days after the effective date of the first registration by the Company pursuant to Section 2.2 and (iv) such rights shall not be more favorable than those granted to the Holders. 2.13 Transfer of Registration Rights. The registration rights ------------------------------- granted to each Investor under this Section 2 may be transferred only: (a) to a transferee who shall acquire not less than 50,000 shares of Series A Preferred Stock, Series B Preferred Stock or Registrable Stock (as adjusted for Recapitalization Events); or (b) in connection with the distribution by an Investor of Series A Preferred Stock, Series B Preferred Stock or Registrable Stock to the beneficial owners (including, without limitation, to partners of a general or limited partnership, shareholders of a corporation and beneficiaries of a trust) of securities of the Investor. The registration rights may only be transferred if the Company is, within a reasonable time after such transfer, furnished with written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being assigned; and only if immediately following such transfer the further disposition of the applicable securities by the transferee or assignee is restricted under the Securities Act. Notwithstanding any provision of this Section 2.13, the registration rights granted to each Investor under this Section 2 may not be assigned to any person or entity which, in the Company's reasonable judgment, is a competitor of the Company. 2.14 "Stand-off" Agreement. In consideration for the Company --------------------- performing its obligations under this Section 2 each Investor agrees for a period of time (not to exceed 180 days) from the effective date of any registration of securities of the Company (upon request of the Company or of the underwriters managing any underwritten offering of the Company's securities) not to sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any Registrable Stock, other than shares of Registrable Stock included in the registration, without the prior written consent of the Company or such underwriters, as the case may be, provided, however, that all -------- ------- officers and directors of the Company and each holder of more than 5% of the outstanding Common Stock shall have entered into similar agreements. -11- 3. Miscellaneous. ------------- 3.1 Notices. All notices, requests, consents and other ------- communications herein (except as stated in the last sentence of this Section 3.1) shall be in writing and shall be mailed by first-class or certified mail, postage prepaid, or personally delivered, as follows: (a) If to the Company: Latitude Communications, Inc. 4001 Burton Drive Santa Clara, CA 95054 with a copy to: Mr. Mark A.

For purposes of computing the time periods set forth herein, the date of mailing shall be deemed to be the delivery date. 3.2 Modification; Waiver. Neither this Agreement nor any provision -------------------- hereof may be changed, waived, discharged or terminated orally or in writing, except that any provision of this Agreement may be amended and the observance of any such provision may be waived (either generally or in a particular instance and either retroactively or prospectively) with (but only with) the written consent of (a) the Company, and (b) the Holders of at least 66-2/3% of the Registrable Stock (assuming the exercise and/or conversion of all exercisable or convertible securities). Any amendment or waiver effected in accordance with this paragraph shall be binding upon each Holder of Registrable Securities, and the Company. In the event that an underwriting agreement is entered into between the Company and any Holder, and such -12- underwriting agreement contains terms differing from this Agreement, as to any such Holder the terms of such underwriting agreement shall govern. 3.3 Entire Agreement. This Agreement contains the entire agreement ---------------- between the parties with respect to the transactions contemplated hereby, and supersedes all negotiations, agreements, representations, warranties, commitments, whether in writing or oral, prior to the date hereof. 3.4 Successors and Assigns. Subject to Section 2.13, all of the ---------------------- terms of this Agreement shall be binding upon and inure to the benefit of and be enforceable by the respective successors and assigns of the parties hereto. 3.5 Enforcement. ----------- (a) Remedies at Law or in Equity. If the Company shall default in ---------------------------- any of its obligations under this Agreement or if any representation or warranty made by or on behalf of the Company in this Agreement or in any certificate, report or other instrument delivered under or pursuant to any term hereof shall be untrue or misleading in any material respect as of the date of this Agreement or as of the date it was made, furnished or delivered, each Investor may proceed to protect and enforce its rights by suit in equity or action at law, whether for the specific performance of any term contained in this Agreement, the Company's Articles or for an injunction against the breach of any such term or in furtherance of the exercise of any power granted in this Agreement or the Company's Articles, or to enforce any other legal or equitable right of such Investor or to take any one or more of such actions. In the event any Investor brings such an action against the Company, the prevailing party in such dispute shall be entitled to recover from the losing party all fees, costs and expenses of enforcing any right of such prevailing party under or with respect to this Agreement or the Company's Articles, including without limitation such reasonable fees and expenses of attorneys and accountants, which shall include, without limitation, all reasonable fees, costs and expenses of appeals. (b) Remedies Cumulative; Waiver. No remedy referred to herein is --------------------------- intended to be exclusive, but each shall be cumulative and in addition to any other remedy referred to above or otherwise available to each Investor at law or in equity. No express or implied waiver by any Investor of any default shall be a waiver of any future or subsequent default. The failure or delay of each Investor in exercising any rights granted it hereunder shall not constitute a waiver of any such right and any single or partial exercise of any particular right by any Investor shall not exhaust the same or constitute a waiver of any other right provided herein. -13- 3.6 Execution and Counterparts. This Agreement may be executed in -------------------------- any number of counterparts, each of which when so executed and delivered shall be deemed an original, and such counterparts together shall constitute one instrument. Each party shall receive a duplicate original of the counterpart copy or copies executed by it and by the Company. 3.7 Governing Law and Severability.

The descriptive headings of the Sections hereof are -------- inserted for convenience only and do not constitute a part of this Agreement. -14- AMENDED AND RESTATED REGISTRATION RIGHTS AGT.

The Company has not elected pursuant to the Internal Revenue Code -7- of 1986, as amended ("Code"), to be treated as a Subchapter S corporation or a collapsible corporation pursuant to Section 341(f) or Section 1362(a) of the Code, nor has it made any other elections pursuant to the Code (other than elections which relate solely to methods of accounting, depreciation or amortization) which would have a material effect on the Company, its financial condition, its business as presently conducted or proposed to be conducted or any of its properties or material assets. 3.22 Insurance. The Company has in full force and effect fire and --------- casualty insurance policies, with extended coverage, sufficient in amount (subject to reasonable deductibles) to allow it to replace any of its properties that might be damaged or destroyed.

Representations, Warranties and Covenants of the Purchasers. Each ----------------------------------------------------------- Purchaser severally represents and warrants that: 4.1 Authorization. The execution and delivery of this Agreement and ------------- the Rights Agreement have been duly authorized by the Purchaser and this Agreement and the Rights Agreement constitute its valid and legally binding obligations, legally enforceable against such Purchaser in accordance with their terms, subject as to enforcement to bankruptcy, insolvency, reorganization and other laws of general applicability relating to or affecting creditors' rights, to general equity principles and as to the indemnification provisions contained in Section 2.11 of the Rights Agreement, as limited by applicable law.

Each Purchaser understands that: ----------------------- (a) The Series B Preferred Stock to be sold and issued hereunder (and the Common Stock into which it may be converted) has not been registered under the Securities Act on the ground that no distribution or public offering of the Preferred Stock (or the Common Stock into which it may be converted) is to be effected, and that in connection therewith the Company is relying in part on the representations of the Purchasers set forth in this Section 4. Further, the Series B Preferred Stock (and the Common Stock into which it may be converted) is required to be held indefinitely unless it is subsequently registered under the Securities Act, or an exemption from such registration is available. (b) Except as provided in the Rights Agreement, the Company is under no obligation to file a registration statement with the Securities and Exchange Commission (the "Commission") with respect to the Series B Preferred Stock or the Common Stock into which the Series B Preferred Stock may be converted.

Each Purchaser agrees that (a) it ------------------------ will not offer, sell, pledge, hypothecate or otherwise dispose of the Series B Preferred Stock (or the Common Stock into which it may be converted) unless such offer, sale, pledge, hypothecation or other disposition is (i) registered under the Securities Act, or (ii) in compliance with an opinion of counsel to the Purchasers, delivered to the Company and reasonably acceptable to it, to the effect that such offer, sale, pledge, hypothecation or other disposition is exempt from registration under the Securities Act, and (b) the certificate(s) representing the Series B Preferred Stock (and any Common Stock into which it may be converted) shall bear a legend stating in substance: THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER SAID ACT OR, IN THE OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION DOES NOT VIOLATE THE PROVISIONS OF SAID ACT. -9- THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND THE SHAREHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY. Upon request of a holder of Series B Preferred Stock (or the Common Stock into which it has been converted), the Company shall remove the legend set forth above from the certificates evidencing such Series B Preferred or Common Stock or issue to such holder new certificates therefor free of such legend, if with such request the Company shall have received an opinion of counsel selected by the holder and reasonably satisfactory to the Company, in form and substance reasonably satisfactory to the Company, to the effect that a transfer by said holder of such Series B Preferred Stock or Common Stock will not violate the Securities Act. 4.6 Transfer Instructions. Each Purchaser agrees that the Company --------------------- may provide for appropriate stop transfer instructions to implement the provisions of Section 4.5 hereof. 4.7 Economic Risk.

Covenants. --------- 5.1 Inspection. The Company covenants and agrees that, for so long ---------- as any Purchaser holds at least 250,000 shares of Series B Preferred Stock (or Common Stock into which it has been converted), as adjusted for stock splits, stock dividends, recapitalizations, reclassifications and similar events (together herein called "Recapitalization Events") (a "Major Purchaser") or for so long as a beneficial owner of any Purchaser (including, without limitation, partners of a general or limited partnership, shareholders of a corporation and beneficiaries of a trust) holds at least 250,000 shares of Series B Preferred Stock or Registrable Stock (as defined in the Rights Agreement) which has been distributed to it, as adjusted for Recapitalization Events (a "Substantial Beneficial Owner"), the Company will permit any authorized representatives of such Purchaser or Substantial Beneficial Owner, at its expense, to visit and inspect the Company's properties, to examine its books of accounts and records, and to discuss the Company's affairs, finances and accounts with its officers, all at such reasonable times as may be requested by such Purchaser or Substantial Beneficial Owner; provided, that the Company shall not be required by this Section 5.1 to provide access to any information which it reasonably considers to be a trade secret or similar confidential information. 5.2 Financial Statements. The Company will deliver: -------------------- (a) to each Purchaser holding at least 250,000 shares of Series B Preferred Stock (or shares of Common Stock into which such Series B Preferred Stock has been converted) within 30 days after the end of each month following the Closing, a balance sheet of the Company as of the end of each such month and a statement of operations for such month and -10- for the period from the beginning of the current fiscal year to the end of such month, setting forth in each case in comparative form the figures for the corresponding periods of the previous fiscal year; (b) to each purchaser holding more than 250,000 shares of Series B Preferred Stock (or shares of Common Stock into which such Series B Preferred Stock has been converted), within 45 days after the end of each of the first three quarters in each fiscal year of the Company, a balance sheet of the Company as of the end of each such quarter and statements of operations and of cash flows of the Company for each quarter and, in the case of the first, second and third quarterly periods, for the period from the beginning of the current fiscal year to the end of such quarter, setting forth in each case in comparative form the figures for the corresponding period of the previous fiscal year, all in reasonable detail and certified, subject to changes resulting from year-end audit adjustments, by the chief financial officer of the Company ("CFO") to the effect that such financial statements were prepared in accordance with generally accepted accounting principles applied on a basis consistent (except as otherwise disclosed therein and consented to by a majority of the Board, including the approval of the representatives on the Board elected by the holders of the Preferred Stock) with that of preceding periods, and except as otherwise stated therein, present fairly the financial position of the Company as of their date; and (c) to each Purchaser within 90 days after the end of each fiscal year of the Company, a balance sheet of the Company as of the end of such year and statements of operations and of cash flows of the Company for such year, setting forth in each case in comparative form the figures for the previous fiscal year, all in reasonable detail and accompanied by the opinion thereon of independent public accountants of recognized national standing which opinion shall state that such financial statements have been prepared in accordance with generally accepted accounting principles applied on a basis consistent with that of the preceding fiscal year (except as otherwise approved by a majority of the Board), and present fairly and accurately the financial position of the Company as of their date, and that the audit by such accountants in connection with such financial statements has been made in accordance with generally accepted auditing standards. 5.3 Termination of Covenants. The covenants set forth in Sections ------------------------ 5.1, 5.2, 5.6, 5.7 and 5.8 shall terminate and be of no further force or effect immediately upon consummation of the first firm commitment underwritten public offering of securities of the Company pursuant to a registration statement filed by the Company under the Securities Act, where the aggregate sales price of such securities (before deduction of underwriting discounts and expenses of sale) is not less than $10,000,000 and the price per share is not less than Seven Dollars Fifty Cents ($7.50), as adjusted for Recapitalization Events (a "Qualified Public Offering"). 5.4 Public Information. At any time and from time to time after the ------------------ earlier of the close of business on such date as (i) a registration statement filed by the Company under the Securities Act becomes effective, (ii) the Company registers a class of securities under Section 12 of the Securities Exchange Act of 1934, as amended, or any federal statute or code -11- which is a successor thereto (the "Exchange Act"), or (iii) the Company issues an offering circular meeting the requirements of Regulation A under the Securities Act, the Company shall undertake to make available to the public and the Holders (as hereinafter defined), pursuant to Rule 144, such information as is necessary to enable the Holders to make sales of Registrable Stock pursuant to that Rule. The Company shall comply with the current public information requirements of Rule 144 and shall furnish thereafter to any Holder, upon request, a written statement executed by the Company as to the steps the Company has taken to so comply. 5.5 Confidentiality. Any information provided pursuant to Sections --------------- 5.1 and 5.2 shall be used by the Purchasers or any Substantial Beneficial Owner solely in furtherance of its interests as an investor in the Company, and each Purchaser or any Substantial Beneficial Owner shall (except as otherwise required by law) use its best efforts to maintain the confidentiality of all nonpublic information of the Company obtained under said sections, provided the Company makes an appropriate designation of any such confidential information, and provided further, that the Company shall not be obligated to disclose any information, the disclosure of which it believes in good faith would be detrimental to the Company and its shareholders. 5.6 Nondisclosure. All employees, consultants and others at the ------------- Company with access to proprietary information shall sign confidentiality agreements in a form satisfactory to the Board of Directors. 5.7 Right of First Offer. Subject to the terms and conditions set -------------------- forth in this Section 5.7, the Company hereby grants to each Purchaser the right of first offer to purchase, pro rata, all or any part of New Securities (as defined in this Section 5.7) which the Company may, from time to time, propose to sell and issue. A pro rata share, for purposes of this right of first offer, is the ratio that the sum of the number of shares of Common Stock issuable upon conversion of the Series B Preferred Stock then held by such Purchaser bears to the sum of the total number of shares of Common Stock then outstanding plus the number of shares of Common Stock issuable upon conversion of the then outstanding Preferred Stock. (a) Definition of "New Securities." Except as set forth below, ----------------------------- "New Securities" shall mean any shares of capital stock of the Company including Common Stock and Preferred Stock, whether now authorized or not, and rights, options or warrants to purchase said shares of Common Stock or Preferred Stock, and securities of any type whatsoever that are, or may become, convertible into said shares of Common Stock or Preferred Stock. Notwithstanding the foregoing, "New Securities" does not include (i) the Series B Preferred Stock purchased under this Agreement, (ii) the Common Stock issuable upon conversion of the Series B Preferred Stock, (iii) shares of the Company's Common Stock or related options exercisable for such Common Stock issued pursuant to any arrangement approved by the Board of Directors to employees, officers and directors of, or consultants, advisors, customers or vendors to, or other persons performing services for, the Company, and (iv) shares, warrants, or options issued to equipment lessors or financial institutions solely in connection with extensions of credit to the Company on terms approved by the Board of Directors, or (v) securities issued in connection -12- with a bona fide business acquisition of or by the Company, whether by merger, consolidation, sale of assets, sale or exchange of stock or otherwise. (b) Notice. If the Company proposes to undertake or ------ undertakes an issuance of New Securities, it shall provide each Purchaser an opportunity to purchase a pro rata share of New Securities by giving notice prior to the issuance of New Securities, as provided in Section 5.7(b)(i) or after the issuance of New Securities, as provided in Section 5.7(b)(ii). (i) Prior to the issuance of New Securities, the Company shall give each Purchaser written notice describing the type of New Securities, and the price and terms upon which the Company proposes to issue the same. Each Purchaser shall then have thirty (30) days from the date of deemed receipt of any such notice to agree to purchase up to its pro rata share of such New Securities for the price and upon the terms specified in the notice by giving written notice to the Company and stating therein the quantity of New Securities it thereby irrevocably commits to purchase. If the Purchasers fail to exercise the right of first offer within said thirty (30) day period, the Company shall have ninety (90) days thereafter to sell or enter into an agreement (pursuant to which the sale of New Securities covered thereby shall be closed, if at all, within sixty (60) days from the date of said agreement) to sell the New Securities not elected to be purchased by Purchasers at a price and upon terms no more favorable to the purchasers of such securities than specified in the Company's notice. In the event the Company has not sold the New Securities or entered into an agreement to sell the New Securities within said ninety (90) day period (or sold and issued New Securities in accordance with the foregoing within sixty (60) days from the date of said agreement), the Company shall not thereafter issue or sell any New Securities, without first offering such securities to each Purchaser in the manner provided in this paragraph (i). (ii) If the Company has not given notice to the Purchasers prior to the issuance of New Securities as provided in Section 5.7(b)(i), then the Company shall give notice to the Purchasers within fifteen (15) days after the issuance of New Securities. Such notice shall describe the type, price and terms of the New Securities. Each Purchaser shall have thirty (30) days from the date of deemed receipt of such notice to elect to purchase from the Company its pro rata share of the New Securities. (The pro rata shares shall be calculated giving effect to the sale of New Securities to the Purchaser). The closing of such sale shall occur within thirty (30) days of the date of notice to the Purchaser. (c) Assignment of Right. The right of first offer hereunder ------------------- is not assignable except by any Purchaser which is a corporation or partnership to any wholly-owned subsidiary or constituent partner or limited partner of such Purchaser. (d) Termination of Right. The right of first offer hereunder -------------------- shall terminate upon the closing of a Qualified Public Offering. 5.8 Vesting Schedule. The Company covenants that any and all shares ---------------- of the Company's Common Stock or related options exercisable for such Common Stock issued employees, officers and directors of, or consultants, advisors, customers or vendors to, or other persons performing services for, the Company shall vest over a period of four years, vesting to -13- begin one year from the date of grant and equally on a monthly basis during the following three years; provided, however, that a different vesting schedule may be effected if such different vesting schedule is approved by the Board of Directors. 5.9 Offer, Sale or Grant of Securities. The Company shall not, at ---------------------------------- any time or from time to time, offer, sell or grant any security, whether or not pursuant to any employee equity incentive plan, without the approval of the Board of Directors. 5.10 Aggregation of Stock.. All Shares (or Common Stock into which -------------------- Shares have been converted) held or acquired by affiliated entities or persons shall be aggregated together for the purpose of determining the availability of any rights under this Section 5. 6. Survival of Agreements. All agreements, representations and ---------------------- warranties contained herein or made in writing in connection with the transactions contemplated hereby shall survive the execution and delivery of this Agreement (despite any investigation at any time made by the Purchasers or on their behalf) and any disposition of the Series B Preferred Stock or of the Common Stock issued upon conversion thereof. All statements contained in any certificate or other instrument executed and delivered by the Company or its duly authorized officers or representatives pursuant hereto in connection with the transactions contemplated hereby shall be deemed representations by the Company hereunder. 7.

Enforcement. ----------- (a) Remedies at Law or in Equity. If the Company shall default ---------------------------- in any of its obligations under this Agreement or if any representation or warranty made by or on behalf of the Company in this Agreement or in any certificate, report or other instrument delivered under or pursuant to any term hereof shall be untrue or misleading in any material respect as of the date of this Agreement or of the Closing Date or as of the date it was made, furnished or delivered, each Purchaser may proceed to protect and enforce its rights by suit in equity or action at law, whether for the specific performance of any term contained in this Agreement, the Company's Articles or for an injunction against the breach of any such term or in furtherance of the exercise of any power granted in this Agreement or the Company's Articles, or to enforce any other legal or equitable right of such Purchaser or to take any one or more of such actions. In the event any Purchaser brings such an action against the Company, the prevailing party in such dispute shall be entitled to recover from the losing party all fees, costs and expenses of enforcing -15- any right of such prevailing party under or with respect to this Agreement or the Company's Articles, including without limitation such reasonable fees and expenses of attorneys and accountants, which shall include, without limitation, all reasonable fees, costs and expenses of appeals.

No remedy referred to herein --------------------------- is intended to be exclusive, but each shall be cumulative and in addition to any other remedy referred to above or otherwise available to each Purchaser at law or in equity. No express or implied waiver by any Purchaser of any default shall be a waiver of any future or subsequent default. The failure or delay of each Purchaser in exercising any rights granted it hereunder shall not constitute a waiver of any such right and any single or partial exercise of any particular right by any Purchaser shall not exhaust the same or constitute a waiver of any other right provided herein. 12.

Headings. The descriptive headings of the Sections hereof and the -------- Schedule and Exhibits hereto are inserted for convenience only and do not constitute a part of this Agreement. 15. Waiver of Right of First Refusal.

II The purpose of this corporation is to engage in any lawful act or activity for which a corporation may be organized under the General Corporation Law of California other than the banking business, the trust company business or the practice of a profession permitted to be incorporated by the California Corporations Code. III (a) Authorized Shares. The corporation is authorized to issue two classes ----------------- of shares designated "Common Stock" and "Preferred Stock" respectively. The total number of shares that the corporation is authorized to issue is sixteen million (16,000,000) shares. Ten million (10,000,000) shares shall be Common Stock, par value $.001 per share, and six million (6,000,000) shares shall be Preferred Stock, par value $.001 per share. The Preferred Stock shall be issued in two series. The first series of Preferred Stock shall be designated Series A Preferred Stock and shall consist of three million three hundred thousand (3,300,000) shares. The second series of Preferred Stock shall be designated Series B Preferred Stock and shall consist of two million seven hundred thousand (2,700,000) shares. Upon the Amendment and Restatement of the Articles of Incorporation of this corporation as set forth herein, each outstanding share of the class of shares previously designated Series A Preferred Stock is converted into and reconstituted as one share of the series of shares designated Series A Preferred Stock. The Liquidation Amount for the Series A Preferred Stock is one dollar ($1.00) per share and the Liquidation Amount for the Series B Preferred Stock is two dollars and seventy-five cents ($2.75) per share, in each case subject to proportional and equitable adjustment for stock splits, reverse splits and similar recapitalizations. (b) Liquidation. ----------- (1) Upon the voluntary or involuntary liquidation, winding up or dissolution of the corporation, out of the assets available for distribution to shareholders, the holders of Series A Preferred Stock shall be entitled to receive, in preference to any payment to the holders of Common Stock, the Liquidation Amount for the Series A Preferred Stock for each share of Series A Preferred Stock then held by them plus any dividends previously declared and unpaid on such Series A Preferred Stock and the holders of Series B Preferred Stock shall be entitled to receive, in preference to any payment to the holders of Common Stock, the Liquidation Amount for the Series B Preferred Stock for each share of Series B Preferred Stock then held by them plus any dividends previously declared and unpaid on such Series B Preferred Stock. In the event the assets of the corporation are insufficient to pay the entirety of such amount required to be paid to the holders of Series A Preferred Stock and to the holders of Series B Preferred Stock under this paragraph (1), the entire remaining assets shall be paid ratably to the holders of Series A Preferred Stock and to the holders of Series B Preferred Stock (so that each shall receive the same percentage of the applicable preferential amount) and the Common Stock shall receive nothing. (2) After the entirety of the amount required under paragraph (1) has been paid to the holders of Series A Preferred Stock and to the holders of Series B Preferred Stock, the remaining assets shall be paid ratably to the holders of Common Stock. (3) For the purposes of this subdivision (b), a liquidation, winding up or dissolution is deemed to include the acquisition of the corporation by another entity, whether by merger, transfer of all or substantially all the assets or otherwise, or a transaction or series of related transactions in which more than 50% of the voting power of the corporation is transferred. (4) Whenever the distribution provided for in this subdivision (b) shall be payable in securities or property other than cash, the value of such distribution shall be the fair market value of such securities or other property as determined in good faith by the Board of Directors. (5) Each holder of an outstanding share of Preferred Stock shall be deemed to have consented, for purposes of Sections 502, 503 and 506 of the General Corporation Law of California, to distributions made by the corporation in connection with the repurchase at cost of shares of Common Stock issued to or held by officers, directors, employees or consultants upon termination of their employment or services pursuant to agreements providing for the right of said repurchase between the corporation and such persons, provided that the terms of such repurchase shall have been approved by the Board. (c) Voting Rights. ------------- (1) Each holder of Common Stock is entitled to one vote per share of Common Stock and each holder of Preferred Stock is entitled to a number of votes equal to the number of shares of Common Stock into which the holder's Preferred Stock is then convertible; for such purpose, any and all fractional shares otherwise issuable to each holder of Preferred Stock shall be aggregated and any resulting fractional shall be rounded off to the nearest whole number of shares (with one-half being rounded up). Except as provided by law or by paragraph -2- (2) following, the Common Stock and Preferred Stock shall vote together as a single class on all matters to come before the shareholders for approval. (2) In addition to any class or series voting rights under applicable law, without the approval of at least two-thirds of the outstanding shares of Preferred Stock voting as a separate class, the corporation shall not: (i) amend the articles of incorporation or the bylaws; (ii) redeem or otherwise acquire any Common Stock, either directly or through a subsidiary, other than pursuant to redemption or repurchase provisions approved by the Board of Directors; (iii) redeem or otherwise acquire any Preferred Stock, either directly or through a subsidiary; (iv) authorize or issue another class or series of equity securities or any securities convertible into, or exchangeable for, equity securities having rights, preferences or privileges greater than, senior to or on a parity with either the Series A Preferred Stock or the Series B Preferred Stock; (v) merge or consolidate with or into any other corporation (directly or indirectly through one or more subsidiaries), sell all or substantially all its assets, or engage in any reorganization or recapitalization of the Company or change of control transaction or any reclassification or other similar change of, or with respect to, any stock; or (vi) voluntarily elect to wind up and dissolve. (d) Conversion. ---------- (1) Subject to paragraph (2) below, the Preferred Stock shall be convertible into Common Stock at any time at the option of the respective holders of Preferred Stock. (2) The Preferred Stock shall automatically be converted into Common Stock immediately upon the closing of a firm commitment underwritten public offering of Common Stock pursuant to an effective registration statement on Form S-1 under the Securities Act of 1933 covering the offer and sale of Common Stock by the corporation to the public at an aggregate offering price of at least $10,000,000 and a per share offering price to the public at least equal to seven dollars and fifty cents ($7.50). (3) For the purposes of any conversion under either paragraph (1) or paragraph (2) above, the number of shares of Common Stock issuable with respect to shares of a series of Preferred Stock upon conversion shall be determined by dividing the aggregate dollar equivalent Liquidation Amount of all shares of such series of Preferred Stock at any one time surrendered for conversion by any one holder thereof by the applicable conversion price for such series in effect at the date of conversion. The initial conversion price per share for each series of the Preferred Stock shall be the Liquidation Amount for such series per share, and such -3- conversion price shall be subject to adjustment from time to time as provided in paragraph (5) of this subdivision (d). Upon conversion, no fractional shares shall be issued and the corporation shall in lieu thereof pay in cash the value of any remaining fraction, taking the conversion price in effect at the time as the value of a whole share of Common Stock; for such purpose, any and all fractional shares otherwise issuable to each holder of shares of a series of Preferred Stock shall be aggregated and any resulting fractional share shall be paid in cash as provided earlier in this sentence. The corporation shall reserve and keep reserved out of its authorized but unissued shares of Common Stock sufficient shares to effect the conversion of all shares of Preferred Stock outstanding from time to time. (4) A holder of Preferred Stock desiring to convert shall deliver the share certificate to the corporation at its principal executive office, accompanied by a written request to convert, specifying the number of shares to be converted. The endorsement of the share certificate and the request to convert shall be in form reasonably satisfactory to the corporation. At the close of business on the date of such delivery, the conversion shall be deemed to have occurred and the person entitled to receive share certificates for Common Stock to which he is entitled upon the conversion. Upon the automatic conversion of Preferred Stock pursuant to paragraph (2) above, the holder of Preferred Stock shall similarly deliver the share certificate to the corporation and the Preferred Stock shall not be deemed to have been converted to Common Stock until immediately prior to the closing of a sale of securities as described in paragraph (2). (5) If at any time or from time to time the corporation shall declare or pay, without consideration, any dividend on the Common Stock payable in Common Stock or in any right to acquire Common Stock for no consideration, or shall subdivide its outstanding shares of Common Stock into a greater number of shares, the conversion price in effect immediately prior to such subdivision shall be proportionately and equitably reduced and conversely, in case the outstanding shares of Common Stock of the corporation shall be combined into a smaller number of shares, the conversion price in effect immediately prior to such combination shall be proportionately and equitably increased. (6) If at any time or from time to time the corporation alters its capital structure so as to change the rights, privileges and preferences of the Common Stock or changes the Common Stock into the same or a different number of shares of any other class or classes of stock, whether by capital reorganization, reclassification or otherwise (except pursuant to a transaction constituting a liquidation pursuant to paragraph (b)(3) above), then each series of Preferred Stock shall be convertible into such number and type of other securities as the holders of such series of Preferred Stock would have received if they had converted the shares of such series of Preferred Stock held by them immediately prior to such reorganization or recapitalization. (7) Promptly after any change in the conversion price for a series of Preferred Stock, the corporation shall cause to be prepared a written statement setting forth in detail the facts and the revised conversion ratio. The statement shall be signed by the chief executive officer and by the chief financial officer and filed with the secretary of the corporation. A copy of the statement shall be promptly mailed to each holder of such series of Preferred Stock at its last known address on the stock records of the corporation. -4- (e) Dividends. --------- (1) The holders of Series A Preferred Stock and the holders of Series B Preferred Stock are entitled to receive, out of funds legally available therefor, if, when and as declared by the board of directors, an annual per share, non-cumulative dividend equal to ten percent (10%) of the Liquidation Amount for their respective series of Preferred Stock prior and in preference to any dividends (whether in cash or other property, and whether or not any such property consists of securities of any third party) payable on account of the Common Stock. (2) No dividends shall be paid on any share of Common Stock unless a dividend is paid with respect to all outstanding shares of Series A Preferred Stock and all outstanding shares of Series B Preferred Stock in amounts equal to or greater than (on an as-converted basis) the amount paid on the Common Stock. (3) No dividend shall be payable without the approval of the Board of Directors. (f) Board of Directors. ------------------ (1) The Board of Directors of the corporation shall consist of five members. Two members shall be elected by (and may only be removed by) the holders of the Preferred Stock, voting as a separate class. One member shall be elected by (and may only be removed by) the holders of Common Stock, voting as a separate class. Two members shall be elected only by (and may only be removed by) the holders of the Preferred Stock and Common Stock, voting together as a single class. (2) If the office of any director becomes vacant, such director's replacement shall be elected by the class (or classes, as applicable) of shares of which such director is the representative. (g) No Impairment. The corporation will not, through any reorganization, ------------- transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action not permitted hereunder, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed under this Article III and in the taking of all such action as may be necessary or appropriate in order to protect the rights, privileges and preferences of the holders of the Preferred Stock against impairment. (h) Notices of Record Date. In the event of the establishment by the ---------------------- corporation of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend (other than a cash dividend) or other distribution, or any right to subscribe for, purchase or otherwise acquire any shares of stock of any class or any other securities or property, or to receive any other right, the corporation shall mail to each holder of Preferred Stock at least twenty (20) days prior to the date specified therein a notice specifying the date on which any such record is to be taken for the purpose of such dividend, distribution or rights, and the amount and character of such dividend, distribution and right. -5- IV (a) The liability of the directors of this corporation for monetary damages shall be eliminated to the fullest extent permissible under California law. (b) This corporation is authorized to provide indemnification of agents (as defined in Section 317 of the California Corporations Code) through bylaw provisions, agreements with agents, vote of shareholders or disinterested directors or otherwise, in excess of the indemnification otherwise permitted by Section 317 of the California Corporations Code, subject only to the applicable limits set forth in Section 204 of the California Corporations Code with respect to actions for breach of duty to the corporation and its shareholders. (c) Any repeal of modifications of the foregoing provisions of this Article shall not adversely affect any right of indemnification or limitation of liability of an agent of this corporation relating to acts or omissions occurring prior to such repeal or modification." 3. The amended and restated Articles of Incorporation have been duly approved by the Board of Directors of the corporation. 4. The foregoing amendment was approved by the required vote of shareholders in accordance with Section 902 of the California General Corporation Law. The total number of outstanding shares of Common Stock of the corporation is 1,778,000, the total number of outstanding shares of Series A Preferred Stock of the corporation is 3,175,000, and the corporation has no other class of securities outstanding. The number of shares voting in favor of the amendment equaled or exceeded the vote required. The percentage vote required was more than 50% of the Common Stock and at least 66-2/3% of the Series A Preferred Stock, each voting separately as a class. -6- The undersigned declare under penalty of perjury under the laws of the State of California that the matters set forth in this certificate are true and correct of their own knowledge.

Upon written notice to the Founder within fifteen (15) business days of receipt by each Purchaser of notification from Founder of the proposed sale, a Purchaser may sell that number of shares of Co-Sale Securities equal to the total number of shares to be sold in the transaction multiplied by a fraction, the numerator of which is the number of shares of Co-Sale Securities held by such Purchaser and the denominator of which is the number of shares of Co-Sale Securities held by all selling Purchasers plus the Founder. 1.2 Limitations on Right of Co-Sale. Section 1.1 of this Agreement shall ------------------------------- not apply where the sale, assignment, transfer or other conveyance of Co-Sale Securities by the Founder is: (a) to the Founder's spouse, parents, or children or other members of the Founder's family (including relatives by marriage), or to a custodian, trustee or other fiduciary for the account of the Founder or members of his family in connection with a bona fide estate planning transaction; ---- ---- (b) by way of bequest or inheritance upon death; (c) to the Company; (d) by way of a bona fide gift; ---- ---- (e) by way of any pledge of Co-Sale Securities made by a Founder pursuant to a bona fide loan transaction that creates a mere security interest; ---- ---- provided, however, that any transferees pursuant to this Section 1.2 shall - -------- ------- receive and hold such shares subject in all respects to the provisions of this Co-Sale Agreement, and that there shall be no further transfer of such shares except in accordance herewith. 1.3 Termination of Co-Sale Right.

RECITALS -------- The Company and certain of the Investors have entered into a Series A Preferred Stock Purchase Agreement dated April 22, 1993 (the "First Series A Purchase Agreement") and the Company and another Investor have entered into a Series A Preferred Stock Purchase Agreement dated September 13, 1993 (the "Second Series A Purchase Agreement"), pursuant to both of which certain Investors (the "Series A Investors") acquired shares of the Company's Series A Preferred Stock (the "Series A Shares"). The Company and certain other Investors (the "Warrant Investors") have entered into an Equipment Lease Agreement dated as of June 30, 1993. In connection with the Equipment Lease Agreement, the Company has issued warrants (the "Warrants") to the Warrant Investors to purchase an aggregate of 60,500 shares of the Company's Series A Preferred Stock (the "Warrant Shares"). The Company and certain of the Investors (the "Series B Investors") are entering into a Series B Preferred Stock Purchase Agreement dated June 1, 1994 (the "Series B Purchase Agreement"), pursuant to which the Series B Investors are acquiring shares of the Company's Series B Preferred Stock (the "Series B Shares"). The Company, the Series A Investors and the Warrant Investors have entered into the First Amended and Restated Registration Rights Agreement dated July 19, 1993 (the "Prior Rights Agreement"), and wish to amend the Prior Rights Agreement to grant the Series B Investors the registration rights provided herein. NOW, THEREFORE, in consideration of the mutual promises and covenants contained herein, the parties agree as follows: 1. Termination of Prior Rights. Effective upon the execution of this --------------------------- Agreement by the Company and by the holders of at least 66 2/3% of the aggregate of the Series A Shares and the Warrant Shares, the Prior Rights Agreement is hereby amended and restated to read in its entirety as set forth herein. 2. Registration. ------------ 2.1 Definitions. As used herein, the following terms, have the ----------- following meanings: (a) "Forms S-1," "S-2" and "S-3:" The forms so designated, promulgated by the Commission for registration of securities under the Securities Act of 1933, as amended (the "Securities Act"), and any forms succeeding to the functions of such forms, whether or not bearing the same designation. (b) "Commission:" The Securities and Exchange Commission or any other federal agency at the time administering the Securities Act. (c) "Holder:" A holder of Registrable Stock, provided that anyone who acquires any Registrable Stock in a distribution pursuant to a registration statement filed by the Company under the Securities Act shall not thereby be deemed to be a "Holder." (d) "Register," "registered" and "registration" refer to a registration effected by filing a registration statement in compliance with the Securities Act, and the declaration or ordering by the Commission of effectiveness of such registration statement. (e) "Registrable Stock:" (i) the shares of Common Stock issuable or issued upon conversion of the Series A Shares, (ii) The shares of Common Stock issuable or issued upon conversion of the Series B Shares, (iii) the shares of Common Stock issuable or issued upon conversion of the Warrant Shares (the shares of Common Stock referred to in clauses (i), (ii), (iii) and (iv) hereof are collectively referred to hereafter as the "Stock"), and (iv) any other shares of Common Stock of the Company issued as (or issuable upon the conversion or exercise of any warrant, right or other security which is issued as) a dividend or other distribution with respect to, or in exchange for or in replacement of, the Stock, excluding in all cases, however, any Registrable Securities sold by a person in a transaction in which his or her rights under this Agreement are not assigned; provided, however, that Common Stock or other securities shall only be treated - -------- ------- as Registrable Stock if and so long as they have not been (A) sold to or through a broker or dealer or underwriter in a public distribution or a public securities transaction, or (B) sold in a transaction exempt from the registration and prospectus delivery requirements of the Securities Act under Section 4(1) thereof so that all transfer restrictions, and restrictive legends with respect thereto, if any, are removed upon the consummation of such sale. -2- 2.2 Required Registration. --------------------- (a) If the Holder or Holders of an aggregate of at least fifty percent (50%) of the Registrable Stock propose to dispose of their Registrable Stock (such Holder or Holders being herein called the "Initiating Holders"), the Initiating Holders may request the Company in writing to effect such registration, stating the number of shares of Registrable Stock to be disposed of by such Initiating Holders and the intended method of disposition, including, but not limited to, registration on Form S-1. Upon receipt of such request, the Company shall give prompt written notice thereof to all other Holders, whereupon such other Holders shall give written notice to the Company within 20 days after the date of the Company's notice (the "Notice Period") if they propose to dispose of any shares of Registrable Stock pursuant to such registration, stating the number of shares of Registrable Stock to be disposed of by such Holder or Holders and the intended method of disposition. (b) The Company will use its best efforts to effect promptly after the Notice Period the registration under the Securities Act of all shares of Registrable Stock specified in the requests of the Initiating Holders and the requests of the other Holders subject, however, to the limitations set forth in Section 2.4. 2.3 Registration Procedures. Whenever the Company is required by the ----------------------- provisions of this Section 2 to use its best efforts to effect promptly the registration of shares of Registrable Stock, the Company will: (a) prepare and file with the Commission a registration statement with respect to such shares and use its best efforts to cause such registration statement to become and remain effective as provided herein; (b) prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective and current and to comply with the provisions of the Securities Act with respect to the disposition of all shares covered by such registration statement, including such amendments and supplements as may be necessary to reflect the intended method of disposition from time to time of the prospective seller or sellers of such shares, but for no longer than one hundred twenty (120) days subsequent to the effective date of such registration in the case of a registration statement on Form S-1 or S-2 and for no longer than ninety (90) days in the case of a registration statement on Form S-3; (c) furnish to each prospective seller such number of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as such seller may reasonably request in order to facilitate the public sale or other disposition of the shares owned by such seller; (d) use its best efforts to register or qualify the shares covered by such registration statement under such other securities or blue sky or other applicable laws of such jurisdiction within the United States as each prospective seller shall reasonably request, to enable such seller to consummate the public sale or other disposition in such jurisdictions of the shares -3- owned by such seller; provided, however, that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not at the time so qualified or to take any action which would subject it to service of process in suits other than those arising out of the offer or sale of the Registrable Stock covered by such registration statement in any jurisdiction where it is not at the time so subject; and (e) furnish to each prospective seller, to the extent requested by such seller, a signed counterpart, addressed to the prospective sellers, of (i) an opinion of counsel for the Company, dated the closing date of the sale of the applicable Registrable Stock, and (ii) a "comfort" letter signed by the independent public accountants who have certified the Company's financial statements included in the registration statement, covering substantially the same matters with respect to the registration statement (and the prospectus included therein) and (in the case of the "comfort" letter) with respect to events subsequent to the date of the financial statements, as are customarily covered in opinions of issuer's counsel and in "comfort" letters delivered to the underwriters in underwritten public offerings of securities. 2.4 Limitations on Required Registrations. ------------------------------------- (a) The Company shall not be required to effect more than two registrations pursuant to Section 2.2. The Company shall not be required to effect any registration unless the anticipated aggregate offering price, net of underwriting discounts and commissions, would exceed $2,000,000. (b) The Company shall not be required to cause a registration requested pursuant to Section 2.2 to become effective prior to the earlier of (i) four years after the date of the first closing under the First Series A Purchase Agreement or (ii) six (6) months after the Company's initial registration with the Commission (other than a registration effected solely to implement an employee benefit plan or a transaction to which Rule 145 of the Commission is applicable). (c) The Company shall not register securities for sale for its own account or for the account of holders of securities other than Registrable Stock in any registration requested pursuant to Section 2.2 without the written consent of Initiating Holders who hold at least 51% of the Registrable Stock as to which registration has been requested, unless such securities are entitled to be included in such registration only to the extent that the inclusion of such securities will not diminish the amount of Registrable Stock included in such registration or otherwise materially and adversely affect the right of the Initiating Holders to have their Registrable Securities registered. The Company may not cause any other registration of securities for sale for its own account (other than a transaction to which Rule 145 of the Commission is applicable or a registration effected solely to implement an employee benefit plan) to be initiated after a registration requested pursuant to Section 2.2 and to become effective less than 90 days after the effective date of any registration requested pursuant to Section 2.2. (d) Whenever a requested registration is for an underwritten offering, only shares which are to be included in the underwriting may be included in the registration. Notwithstanding the provisions of Sections 2.2(b) and 2.4(c), if the underwriter determines that -4- (i) marketing factors require a limitation of the total number of shares to be underwritten, or (ii) the offering price per share would be reduced by the inclusion of the shares of the Company or others, then the number of shares to be included in the registration and underwriting shall first be allocated among all Holders who indicated to the Company their decision to distribute any of their Registrable Stock through such underwriting, in proportion, as nearly as practicable, to the respective numbers of shares of Registrable Stock owned by such Holders at the time of filing the registration statement, then, if any, to the Company and others. No stock excluded from the underwriting by reason of the underwriter's marketing limitation shall be included in such registration. If the Company disapproves of any such underwriting, the Company may elect to withdraw therefrom by written notice to the Initiating Holders and the underwriter. The securities so withdrawn from such underwriting shall also be withdrawn from such registration. (e) If at the time of any request to register Registrable Stock pursuant to Section 2.2 hereof, the Company is engaged, or has fixed plans to engage within 90 days of the time of the request, in a registered public offering as to which the Holders may include Registrable Stock pursuant to Section 2.5 hereof or the Company is engaged in any other activity which, in the good faith determination of the Board, would be adversely affected by the requested registration to the material detriment of the Company, then the Company may at its option direct that such request be delayed for a period not in excess of 120 days from the effective date of such offering, or the date of commencement of such other material activity, as the case may be, such right to delay a request to be exercised by the Company not more than once in any 12- month period while the rights set forth in Section 2.2 are in effect. 2.5 Incidental Registration. If the Company at any time proposes to ----------------------- register any of its Common Stock under the Securities Act (other than a registration effected solely to implement an employee benefit plan or a transaction to which Rule 145 of the Commission is applicable), it will each such time give written notice to all Holders of its intention so to do. Upon the written request of a Holder or Holders given within 20 days after receipt of any such notice (stating the number of shares of Registrable Stock to be disposed of by such Holder or Holders and the intended method of disposition), the Company will use its best efforts to cause all such shares intended to be disposed of, which the Holders shall have requested registration thereof, to be registered under the Securities Act so as to permit the disposition (in accordance with the methods in said request) by such Holder or Holders of the shares so registered, subject, however, to the limitations set forth in Section 2.6. 2.6 Limitations on Incidental Registration. If the registration of -------------------------------------- which the Company gives notice pursuant to Section 2.5 is for an underwritten offering, only securities which are to be included in the underwriting may be included in the registration. Notwithstanding any provision of Section 2.5, if the underwriter determines that marketing factors require a limitation of the number of shares to be underwritten, the underwriter may exclude or otherwise limit the number of shares, including Registrable Stock, requested to be included in the registration and underwriting to a number of shares not less than twenty percent (20%) of the aggregate number of shares to be disposed of in the registration and underwriting, unless the registration is for an initial public offering (in which case the percentage may be less). The Company shall so advise all Holders of any limitation (except those Holders who have not indicated to the -5- Company their decision to distribute any of their Registrable Stock through such underwriting), and the number of shares, including Registrable Stock, that may be included in the registration and underwriting shall be allocated among the selling shareholders in proportion, as nearly as practicable, to the respective amounts of securities, including Registrable Stock, owned by such Holders and other selling shareholders entitled to be included therein at the time of filing the registration statement, in accordance with Section 2.12(a). No Registrable Stock excluded from the underwriting by reason of the underwriter's marketing limitation shall be included in such registration. If any Holder disapproves of any such underwriting, such person may elect to withdraw therefrom by written notice to the Company and the underwriter. The Registrable Stock and/or other securities so withdrawn from such underwriting shall also be withdrawn from such registration. The registration rights granted under Sections 2.2, 2.5 and 2.8 shall terminate as to any Holder or permissible transferee or assignee of such rights if such person (a) holds one percent (1%) or less of the outstanding shares of Common Stock of the Company (on an as-converted basis) and (b) is permitted to sell all of the Registrable Stock held by him or her in a single transaction to the public pursuant to Rule 144. 2.7 Designation of Underwriter. -------------------------- (a) In the case of any registration effected pursuant to Section 2.2 or Section 2.8, a majority in interest of the requesting Holders shall have the right to designate the managing underwriter in any underwritten offering, which underwriter shall be reasonably acceptable to the Company. (b) In the case of any registration initiated by the Company, the Company shall have the right to designate the managing underwriter in any underwritten offering. 2.8 Form S-3. The Company shall register its Common Stock under the -------- Securities Exchange Act of 1934, as amended, as promptly as reasonably practicable following the effective date of the first registration of any securities of the Company on Form S-1 and the Company shall thereafter effect all qualifications and compliances as would permit or facilitate the sale and distribution of its stock on Form S-3, to the extent available. After the Company has qualified for the use of Form S-3, the Holders shall have the right to request an unlimited number of registrations on Form S-3 (such requests shall be in writing and shall state the number of shares of Registrable Stock to be disposed of and the intended method of disposition) except that the Company (a) shall not be required to effect more than one registration pursuant to this Section 2.8 in any six-month period, and (b) shall not be required to effect a registration pursuant to this Section 2.8 unless the Holder or Holders requesting registration hold an aggregate of at least thirty percent (30%) of the Registrable Stock then outstanding and propose to dispose of shares of Registrable Stock having an aggregate expected public offering price (before deduction of underwriting discounts and expenses of sale) of at least $500,000. The Company shall give notice to all Holders of the receipt of a request for registration pursuant to this Section 2.8 and shall provide a reasonable opportunity for other -6- Holders to participate in the registration, provided that if the registration is for an underwritten offering, the terms of Section 2.4(d) shall apply to all participants in such offering. Subject to the foregoing, the Company will use its best efforts to effect promptly the registration of all shares of Registrable Stock on Form S-3 to the extent requested by the Holder or Holders thereof. 2.9 Cooperation by Prospective Sellers. ---------------------------------- (a) Each prospective seller of Registrable Stock, and each underwriter designated by each such seller, will furnish to the Company such information as the Company may reasonably require from such seller or underwriter in connection with the registration statement (and the prospectus included therein). (b) Failure of a prospective seller of Registrable Stock to furnish the information and agreements described in this Section 2 shall not affect the obligations of the Company under this Section 2 to the remaining sellers who furnish such information and agreements unless, in the reasonable opinion of counsel to the Company or the underwriters, such failure impairs or may impair the viability of the offering or the legality of the registration statement or the underlying offering. (c) The Holders holding shares included in the registration statement will not (until further notice) effect sales thereof after receipt of telegraphic or written notice from the Company to suspend sales to permit the Company to correct or update a registration statement or prospectus but the obligations of the Company with respect to maintaining any registration statement current and effective shall be extended by a period of days equal to the period such suspension is in effect unless (i) such extension would result in the Company's inability to use the financial statements in the registration statement initially filed pursuant to the Holder or Holders' request and (ii) such correction or update did not result from the Company's acts or failures to act. At the end of the period during which the Company is obligated to keep the registration statement current and effective as described in Section 2.3(b) (and any extensions thereof required by the preceding sentence), the Holders holding shares included in the registration statement shall discontinue sales of shares pursuant to such registration statement upon receipt of notice from the Company of its intention to remove from registration the shares covered by such registration statement which remain unsold, and such Holders shall notify the Company of the number of shares registered which remain unsold immediately upon receipt of such notice from the Company. 2.10 Expenses of Registration. All expenses incurred in effecting any ------------------------ registration pursuant to this Section 2 including, without limitation, all registration and filing fees, printing expenses, expenses of compliance with blue sky laws, fees and disbursements of counsel for the Company and expenses of any audits incidental to or required by any such registration, shall be borne by the Company, except that (a) all expenses, fees and disbursements of any counsel retained by the Holders and all underwriting discounts and commissions shall be borne by the Holders holding the securities registered pursuant to such registration, according to the quantity of the securities so registered; (b) the Company shall not be required to pay for any -7- expenses of any registration proceeding begun pursuant to Section 2.2 if the registration request is subsequently withdrawn at the request of the Holders of a majority of the Registrable Securities to be registered (in which case all participating Holders shall bear such expenses), unless the Holders of a majority of the Registrable Securities agree to forfeit their right to one demand registration pursuant to Section 2.2, provided however, that if immediately prior to the time of such withdrawal, the Holders have learned of a materially adverse change in the condition, business or prospects of the Company from that known to the Holders at the time of their request, then the Holders shall not be required to pay any of such expenses and shall retain their rights pursuant to Section 2.2; and (c) the Company shall not be required to pay any expenses associated with any registration of Registrable Stock requested by Holders pursuant to Section 2.8. 2.11 Indemnification. --------------- (a) To the extent permitted by law, the Company will indemnify each Holder requesting or joining in a registration, each agent, officer and director of such Holders, each person controlling such Holder and each underwriter and selling broker of the securities so registered (collectively, "Indemnitees") against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any prospectus, offering circular or other document incident to any registration, qualification or compliance (or in any related registration statement, notification or the like) or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances in which they were made, or any violation by the Company of any rule or regulation promulgated under the Securities Act applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification or compliance, and will reimburse each such Indemnitee, promptly and on a current basis from time to time, for any legal and any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action, provided, however, that the Company will not be liable in -------- ------- any such case to the extent that any such claim, loss, damage or liability is caused by any untrue statement or omission so made in strict conformity with written information furnished to the Company by an instrument duly executed by such Indemnitees and stated to be specifically for use therein and except that the foregoing indemnity agreement is subject to the condition that, insofar as it relates to any such untrue statement (or alleged untrue statement) or omission (or alleged omission) made in the preliminary prospectus but eliminated or remedied in the amended prospectus on file with the Commission at the time the registration statement becomes effective or in the amended prospectus filed with the Commission pursuant to Rule 424(b) (the "Final Prospectus"), such indemnity agreement shall not inure to the benefit of any underwriter, or any Indemnitee if there is no underwriter, if a copy of the Final Prospectus was not furnished to the person or entity asserting the loss, liability, claim or damage at or prior to the time such furnishing is required by the Securities Act; provided, further, that this indemnity shall not be deemed to relieve any underwriter of any of its due diligence obligations; provided, further, that the indemnity agreement contained in this Section 2.11(a) shall not apply to amounts paid in settlement of any -8- such claim, loss, damage, liability or action if such settlement is effected without the consent of the Company, which consent shall not be unreasonably withheld. (b) To the extent permitted by law, each Holder requesting or joining in a registration and each underwriter of the securities so registered will indemnify the Company and its officers and directors and each other Holder and each person, if any, who controls any thereof within the meaning of Section 15 of the Securities Act and their respective successors against all claims, losses, damages and liabilities or actions in respect thereof arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any prospectus, offering circular or other document incident to any registration, qualification or compliance (or in any related registration statement, notification or the like) or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances in which they were made and will reimburse, promptly and on a current basis from time to time, the Company and each other person indemnified pursuant to this Section 2.11(b) for any legal and any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action, provided, however, that this Section 2.11(b) shall apply only if (and -------- ------- only to the extent that) such statement or omission was made in reliance upon and in strict conformity with written information (including, without limitation, written negative responses to inquiries) furnished to the Company by an instrument duly executed by such Holder or underwriter and stated to be specifically for use in such prospectus, offering circular or other document (or related registration statement, notification or the like) or any amendment or supplement thereto and except that the foregoing indemnity agreement is subject to the condition that, insofar as it relates to any such untrue statement (or alleged untrue statement) or omission (or alleged omission) made in the preliminary prospectus but eliminated or remedied in the amended Prospectus on file with the Commission at the time the registration statement becomes effective or in the Final Prospectus, such indemnity agreement by a Holder other than an underwriter shall not inure to the benefit of (i) the Company and (ii) any underwriter or any Holder, if there is no underwriter, if a copy of the Final Prospectus was not furnished to the person or entity asserting the loss, liability, claim or damage at or prior to the time such furnishing is required by the Securities Act; provided, further, that this indemnity shall not be -------- ------- deemed to relieve any underwriter of any of its due diligence obligations; provided, further, that the indemnity agreement contained in this Section - -------- ------- 2.11(b) shall not apply to amounts paid in settlement of any such claim, loss, damage, liability or action if such settlement is effected without the consent of the Holder or underwriter, as the case may be, which consent shall not be unreasonably withheld, and provided, further, that the obligations of such -------- ------- Holders shall be limited to an amount equal to the proceeds to each such Holder from the sale of Registrable Stock as contemplated herein, unless such claim, loss, damage, liability or action resulted from such Holder's fraudulent misconduct. -9- (c) Each party entitled to indemnification hereunder (the "Indemnified Party") shall give notice to the party required to provide indemnification (the "Indemnifying Party") promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party (at its expense) to assume the defense of any claim or any litigation resulting therefrom, provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be satisfactory to the Indemnified Party, and the Indemnified Party may participate in such defense at such party's expense, and provided, further, that -------- ------- the omission by any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section 2.11 except to the extent that the omission results in a failure of actual notice to the Indemnifying Party and such Indemnifying Party is damaged solely as a result of the failure to give notice. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. (d) The reimbursement required by this Section 2.11 shall be made by periodic payments during the course of the investigation or defense, as and when bills are received or expenses incurred. (e) The obligations under this Section 2.11 shall survive the redemption and conversion, if any, of the Series A Preferred Stock or Series B Preferred Stock, the completion of any offering of Registrable Stock in a registration statement under this Section 2, or otherwise. 2.12 Rights Which May Be Granted to Subsequent Investors. --------------------------------------------------- (a) Within the limitations prescribed by this Section 2.12(a), but not otherwise, the Company may grant to subsequent investors in the Company rights of incidental registration (such as those provided in Section 2.5). Such rights may only pertain to shares of Common Stock, including shares of Common Stock into which any other securities may be converted. Such rights may be granted with respect to (i) registrations actually requested by Initiating Holders pursuant to Section 2.2, but only in respect of that portion of any such registration as remains after inclusion of all Registrable Stock requested by Holders and (ii) registrations initiated by the Company, but only in respect of that portion of such registration as is available under the limitations set forth in Section 2.6 (which limitations shall apply to all Holders) and such rights shall be limited in all cases to sharing in the available portion of the registration in question with Holders, such sharing to be based on the number of shares of Common Stock held by the respective Holders and held by such other investors, plus the number of shares of Common Stock into which other securities held by the Holders and such other investors are convertible, which are entitled to registration rights. With respect to registrations which are for underwritten public offerings, "available portion" shall mean the portion of the underwritten shares which is available as specified in clauses (i) and (ii) of the third sentence of this Section 2.12(a). Shares not included in such underwriting shall not be registered. -10- (b) The Company may not grant to subsequent investors in the Company rights of registration upon request (such as those provided in Section 2.2) unless (i) such rights are limited to shares of Common Stock, (ii) all Holders are given enforceable contractual rights to participate in registrations requested by such subsequent investors (the right of priority of registration being pro rata as between subsequent investors and Holders), where such participation is on a pro rata basis between subsequent investors and Holders, (iii) subject to the limitations described in the final three sentences of Section 2.12(a), such rights shall not become effective prior to 90 days after the effective date of the first registration by the Company pursuant to Section 2.2 and (iv) such rights shall not be more favorable than those granted to the Holders. 2.13 Transfer of Registration Rights. The registration rights granted ------------------------------- to each Investor under this Section 2 may be transferred only: (a) to a transferee who shall acquire not less than 50,000 shares of Series A Preferred Stock, Series B Preferred Stock or Registrable Stock (as adjusted for Recapitalization Events); or (b) in connection with the distribution by an Investor of Series A Preferred Stock, Series B Preferred Stock or Registrable Stock to the beneficial owners (including, without limitation, to partners of a general or limited partnership, shareholders of a corporation and beneficiaries of a trust) of securities of the Investor. The registration rights may only be transferred if the Company is, within a reasonable time after such transfer, furnished with written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being assigned; and only if immediately following such transfer the further disposition of the applicable securities by the transferee or assignee is restricted under the Securities Act. Notwithstanding any provision of this Section 2.13, the registration rights granted to each Investor under this Section 2 may not be assigned to any person or entity which, in the Company's reasonable judgment, is a competitor of the Company. 2.14 "Stand-off" Agreement. In consideration for the Company --------------------- performing its obligations under this Section 2 each Investor agrees for a period of time (not to exceed 180 days) from the effective date of any registration of securities of the Company (upon request of the Company or of the underwriters managing any underwritten offering of the Company's securities) not to sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any Registrable Stock, other than shares of Registrable Stock included in the registration, without the prior written consent of the Company or such underwriters, as the case may be, provided, however, that all -------- ------- officers and directors of the Company and each holder of more than 5% of the outstanding Common Stock shall have entered into similar agreements. -11- 3. Miscellaneous. ------------- 3.1 Notices. All notices, requests, consents and other communications ------- herein (except as stated in the last sentence of this Section 3.1) shall be in writing and shall be mailed by first-class or certified mail, postage prepaid, or personally delivered, as follows: (a) If to the Company: Latitude Communications, Inc. 4001 Burton Drive Santa Clara, CA 95054 with a copy to: Mr. Mark A.

Neither this Agreement nor any provision -------------------- hereof may be changed, waived, discharged or terminated orally or in writing, except that any provision of this Agreement may be amended and the observance of any such provision may be waived (either generally or in a particular instance and either retroactively or prospectively) with (but only with) the written consent of (a) the Company, and (b) the Holders of at least 66-2/3% of the Registrable Stock (assuming the exercise and/or conversion of all exercisable or convertible securities). Any amendment or waiver effected in accordance with this paragraph shall be binding upon each Holder of Registrable Securities, and the Company. In the event that an underwriting agreement is entered into between the Company and any Holder, and such -12- underwriting agreement contains terms differing from this Agreement, as to any such Holder the terms of such underwriting agreement shall govern. 3.3 Entire Agreement. This Agreement contains the entire agreement ---------------- between the parties with respect to the transactions contemplated hereby, and supersedes all negotiations, agreements, representations, warranties, commitments, whether in writing or oral, prior to the date hereof. 3.4 Successors and Assigns. Subject to Section 2.13, all of the terms ---------------------- of this Agreement shall be binding upon and inure to the benefit of and be enforceable by the respective successors and assigns of the parties hereto. 3.5 Enforcement. ----------- (a) Remedies at Law or in Equity. If the Company shall default ---------------------------- in any of its obligations under this Agreement or if any representation or warranty made by or on behalf of the Company in this Agreement or in any certificate, report or other instrument delivered under or pursuant to any term hereof shall be untrue or misleading in any material respect as of the date of this Agreement or as of the date it was made, furnished or delivered, each Investor may proceed to protect and enforce its rights by suit in equity or action at law, whether for the specific performance of any term contained in this Agreement, the Company's Articles or for an injunction against the breach of any such term or in furtherance of the exercise of any power granted in this Agreement or the Company's Articles, or to enforce any other legal or equitable right of such Investor or to take any one or more of such actions. In the event any Investor brings such an action against the Company, the prevailing party in such dispute shall be entitled to recover from the losing party all fees, costs and expenses of enforcing any right of such prevailing party under or with respect to this Agreement or the Company's Articles, including without limitation such reasonable fees and expenses of attorneys and accountants, which shall include, without limitation, all reasonable fees, costs and expenses of appeals. (b) Remedies Cumulative; Waiver. No remedy referred to herein --------------------------- is intended to be exclusive, but each shall be cumulative and in addition to any other remedy referred to above or otherwise available to each Investor at law or in equity. No express or implied waiver by any Investor of any default shall be a waiver of any future or subsequent default. The failure or delay of each Investor in exercising any rights granted it hereunder shall not constitute a waiver of any such right and any single or partial exercise of any particular right by any Investor shall not exhaust the same or constitute a waiver of any other right provided herein. -13- 3.6 Execution and Counterparts. This Agreement may be executed in -------------------------- any number of counterparts, each of which when so executed and delivered shall be deemed an original, and such counterparts together shall constitute one instrument. Each party shall receive a duplicate original of the counterpart copy or copies executed by it and by the Company. 3.7 Governing Law and Severability.

The descriptive headings of the Sections hereof are -------- inserted for convenience only and do not constitute a part of this Agreement. -14- AMENDED AND RESTATED REGISTRATION RIGHTS AGT.
