AGREEMENT AND PLAN OF MERGER

Agreement entered into as of December 17, 2003 by and among Red Hat, Inc., a Delaware corporation (the “Buyer”), Wild Acquisition Corp., a Delaware corporation and a wholly-owned subsidiary of the Buyer (the “Transitory Subsidiary”), and Sistina Software, Inc., a Delaware corporation (the “Company”).

This Agreement contemplates a merger of the Transitory Subsidiary into the Company. In such merger, the stockholders of the Company will receive common stock of the Buyer in exchange for their capital stock of the Company.

For United States federal income tax purposes, it is intended that the Merger shall qualify as a reorganization within the meaning of Section 368(a) of the Code and that this Agreement be adopted by the Parties as a plan of reorganization.

Capitalized terms shall have the meanings ascribed to such terms in Article IX herein.

Now, therefore, in consideration of the representations, warranties and covenants herein contained, the Parties agree as follows.

ARTICLE I

THE MERGER

1.1 The Merger. Upon and subject to the terms and conditions of this Agreement, the Transitory Subsidiary shall merge with and into the Company at the Effective Time. From and after the Effective Time, the separate corporate existence of the Transitory Subsidiary shall cease and the Company shall continue as the Surviving Corporation. The Merger shall have the effects set forth in Section 259 of the Delaware General Corporation Law.

1.2 The Closing. The Closing shall take place at the offices of ▇▇▇▇ and ▇▇▇▇ LLP in Boston, Massachusetts, commencing at 9:00 a.m. local time on the Closing Date.

(f) the Buyer, the Indemnification Representatives and the Escrow Agent shall execute and deliver the Escrow Agreement and the Buyer shall deliver to the Escrow Agent a certificate for the Escrow Shares being placed in escrow on the Closing Date pursuant to Section 1.9.

1.5 Conversion of Shares. At the Effective Time, by virtue of the Merger and without any action on the part of any Party or the holder of any of the following securities:

(a) Each Common Share issued and outstanding immediately prior to the Effective Time (other than Common Shares owned beneficially by the Buyer or the Transitory Subsidiary, Dissenting Shares and Common Shares held in the Company’s treasury) shall be converted into and represent the right to receive (subject to the provisions of Section 1.9) such number of shares of Buyer Common Stock as is equal to the result obtained by dividing (i) the Closing Consideration Amount minus the Preference Amount by (ii) the sum of (A) the number of outstanding Common Shares immediately prior to the Effective Time (after giving effect to the conversion into Common Shares of all outstanding Preferred Shares) and (B) the number of Common Shares issuable upon exercise of all Options and Warrants vested or exercisable, as the case may be, immediately prior to the Effective Time, but excluding the Common Shares issuable due to the acceleration of the Retained Employee Double Trigger Options pursuant to Section 4.12, and dividing such amount by (iii) the average of the last reported sale prices per share of the Buyer Common Stock on the Nasdaq National Market over the ten (10) consecutive trading days ending on the trading day that is one (1) trading day prior to the Closing Date (the “Common Conversion Ratio”). The Common Conversion Ratio shall be subject to equitable adjustment in the event of any stock split, stock dividend, reverse stock split or similar event affecting the Buyer Common Stock between the beginning of such ten-day period and the Effective Time.

(b) Each Series B-1 Preferred Share issued and outstanding immediately prior to the Effective Time (other than Series B-1 Preferred Shares owned beneficially by the Buyer or the Transitory Subsidiary, Dissenting Shares and Preferred Shares held in the Company’s treasury) shall be converted into and represent the right to receive (subject to the provisions of Section 1.9) such number of shares of Buyer Common Stock as is equal to the sum of (i) the result obtained by dividing (x) the Series B-1 Preference Amount by (y) the number of outstanding Series B-1 Preferred Shares immediately prior to the Effective Time and dividing such amount by (z) the average of the last reported sale prices per share of the Buyer Common Stock on the Nasdaq National Market over the ten consecutive trading days ending on the trading day that is one (1) trading day prior to the Closing Date plus (ii) the result obtained by multiplying the Common Conversion Ratio by the number of Common Shares into which each Series B-1 Preferred Share is convertible immediately prior to the Effective Time (the “Series B-1 Preferred Conversion Ratio”). The Series B-1 Preferred Conversion Ratio shall be subject to equitable adjustment in the event of any stock split, stock dividend, reverse stock split or similar event affecting the Buyer Common Stock between the beginning of the ten-day period referred to in the definition of Common Conversion Ratio and the Effective Time.

-2-

(c) Each Series B-2 Preferred Share issued and outstanding immediately prior to the Effective Time (other than Series B-2 Preferred Shares owned beneficially by the Buyer or the Transitory Subsidiary, Dissenting Shares and Preferred Shares held in the Company’s treasury) shall be converted into and represent the right to receive (subject to the provisions of Section 1.9) such number of shares of Buyer Common Stock as is equal to the sum of (i) the result obtained by dividing (x) the Series B-2 Preference Amount by (y) the number of outstanding Series B-2 Preferred Shares immediately prior to the Effective Time and dividing such amount by (z) the average of the last reported sale prices per share of the Buyer Common Stock on the Nasdaq National Market over the ten consecutive trading days ending on the trading day that is one (1) trading day prior to the Closing Date plus (ii) the result obtained by multiplying the Common Conversion Ratio by the number of Common Shares into which each Series B-2 Preferred Share is convertible immediately prior to the Effective Time (the “Series B-2 Preferred Conversion Ratio”). The Series B-2 Preferred Conversion Ratio shall be subject to equitable adjustment in the event of any stock split, stock dividend, reverse stock split or similar event affecting the Buyer Common Stock between the beginning of the ten-day period referred to in the definition of Common Conversion Ratio and the Effective Time.

(d) Each Company Stockholders shall be entitled to receive as of the Closing that number of shares of Buyer Common Stock equal to (i) 90% of the shares into which their Company Shares were converted pursuant to this Section 1.5, minus (ii) his, her or its pro rata share (based on the number of the Merger Shares received by such Indemnifying Stockholder as a percentage of the total number of Merger Shares issued) of the number of shares of Buyer Common Stock having a Value of $3,000,000, in each case, rounded to the nearest whole number (collectively, the “Initial Shares”). The (x) 10% of the shares of Buyer Common Stock into which each Company Stockholders’ Company Shares were converted pursuant to this Section 1.5, plus (y) the aggregate number of shares of Buyer Common Stock having a Value of $3,000,000, in each case, rounded to the nearest whole number (collectively, the “Escrow Shares”), shall be deposited in escrow pursuant to Section 1.9 and shall be held and disposed of in accordance with the terms of the Escrow Agreement. No Company Stockholder shall be entitled to receive any shares of Buyer Common Stock until such time as the Company Stockholder has delivered to the Buyer a completed Investment Representation Letter in the form attached hereto as Exhibit A.

(e) Each Company Share held in the Company’s treasury immediately prior to the Effective Time and each Company Share owned beneficially by the Buyer or the Transitory Subsidiary shall be cancelled and retired without payment of any consideration therefor.

1.6 Dissenting Shares.

(a) Dissenting Shares shall not be converted into or represent the right to receive Merger Shares, unless such Company Stockholder shall have forfeited his, her or its right to appraisal under the Delaware General Corporation Law or properly withdrawn his, her or its demand for appraisal. If such Company Stockholder has so forfeited or withdrawn his, her or its right to appraisal of Dissenting Shares, then (i) as of the occurrence of such event, such holder’s Dissenting Shares shall cease to be Dissenting Shares and shall be converted into and represent the right to receive the Merger Shares issuable in respect of such Company Shares pursuant to Section 1.5, and (ii) promptly following the occurrence of such event, the Buyer shall deliver to such Company Stockholder a certificate representing 90% of the Merger Shares to which such holder is entitled pursuant to Section 1.5 (which shares shall be considered Initial Shares for all purposes of this Agreement) and shall deliver to the Escrow Agent a certificate representing the remaining 10% of the Merger Shares to which such holder is entitled pursuant to Section 1.5 (which shares shall be considered Escrow Shares for all purposes of this Agreement).

(b) The Company shall give the Buyer (i) prompt notice of any written demands for appraisal of any Company Shares, withdrawals of such demands, and any other instruments that relate to such demands received by the Company and (ii) the opportunity to direct all negotiations and proceedings with respect to demands for appraisal under the Delaware General Corporation Law. The Company shall not, except with the prior written consent of the Buyer, make any payment with respect to any demands for appraisal of Company Shares or offer to settle or settle any such demands.

1.7 Fractional Shares. No certificates or scrip representing fractional Initial Shares shall be issued to former Company Stockholders upon the surrender for exchange of Certificates, and such former Company Stockholders shall not be entitled to any voting rights, rights to receive any dividends or distributions or other rights as a stockholder of the Buyer with respect to any fractional Initial Shares that would have otherwise been issued to such former Company Stockholders. In lieu of any fractional Initial Shares that would have otherwise been issued, each former Company Stockholder that would have been entitled to receive a fractional Initial Share from the Buyer or the Transitory Subsidiary shall, upon proper surrender of such person’s Certificates, receive a cash payment equal to the closing price per share of the Buyer Common Stock on the Nasdaq National Market, as reported by Nasdaq, on the business day immediately preceding the Closing Date, multiplied by the fraction of a share that such Company Stockholder would otherwise be entitled to receive.

1.8 Options and Warrants.

(a) As of the Effective Time, all Options, whether vested or unvested, and the Option Plan, insofar as it relates to Options outstanding under such Plan as of the Closing, shall be assumed by the Buyer. Immediately after the Effective Time, each Option outstanding immediately prior to the Effective Time shall be deemed to constitute an option to acquire, on the same terms and conditions as were applicable under such Option at the Effective Time (i) such number of shares of Buyer Common Stock as is equal to the number of Common Shares subject to the unexercised portion of such Option immediately prior to the Effective Time multiplied by the Common Conversion Ratio (with any fraction resulting from such multiplication to be rounded down to the nearest whole number), plus (ii) if, during the Initial Earn-Out Period, the Buyer achieves Bookings of at least $1,500,000, such number of shares of

-4-

Buyer Common Stock as is equal to the number of Common Shares subject to the unexercised portion of such Option immediately prior to the Effective Time multiplied by the Initial Earn-out Share Conversion Ratio (with any fraction resulting from such multiplication to be rounded down to the nearest whole number), plus (iii) if, during the Second Earn-Out Period, the Buyer achieves Bookings of at least $2,000,000, such number of shares of Buyer Common Stock as is equal to the number of Common Shares subject to the unexercised portion of such Option immediately prior to the Effective Time multiplied by the Second Earn-out Share Conversion Ratio (with any fraction resulting from such multiplication to be rounded down to the nearest whole number) and plus (iv) if, during the Full Earn-Out Period, the Buyer achieves Bookings of at least $7,000,000, such number of shares of Buyer Common Stock as is equal to the number of Common Shares subject to the unexercised portion of such Option immediately prior to the Effective Time multiplied by the Full Earn-out Share Conversion Ratio (with any fraction resulting from such multiplication to be rounded down to the nearest whole number). The exercise price per share of each such assumed Option shall be equal to the exercise price of such Option immediately prior to the Effective Time, divided by the Common Conversion Ratio (rounded up to the nearest whole cent). The term, exercisability, vesting schedule, status as an “incentive stock option” under Section 422 of the Code, if applicable, and all of the other terms of the Options shall otherwise remain unchanged. In the event any such Option is exercised prior to issuance of the Initial Earn-out Shares, the Second Earn-out Shares or the Full Earn-out Shares, as the case may be, the Earn-out Shares issuable to such Option holder with respect to the portion of the Option so exercised shall be issued to the such Option holder at the time of issuance of the Initial Earn-out Shares, the Second Earn-out Shares or the Full Earn-out Shares, as the case may be.

(b) As of the Effective Time, all Warrants, whether exercisable or not, shall be assumed by the Buyer. Immediately after the Effective Time, each Warrant outstanding immediately prior to the Effective Time shall be deemed to constitute the right to acquire, on the same terms and conditions as were applicable under such Warrant at the Effective Time, (i) such number of shares of Buyer Common Stock as is equal to the number of Common Shares subject to the unexercised portion of such Warrant immediately prior to the Effective Time multiplied by the Common Conversion Ratio (with any fraction resulting from such multiplication to be rounded down to the nearest whole number), plus (ii) if, during the Initial Earn-Out Period, the Buyer achieves Bookings of at least $1,500,000, such number of shares of Buyer Common Stock as is equal to the number of Common Shares subject to the unexercised portion of such Warrant immediately prior to the Effective Time multiplied by the Initial Earn-out Share Conversion Ratio (with any fraction resulting from such multiplication to be rounded down to the nearest whole number), plus (iii) if, during the Second Earn-Out Period, the Buyer achieves Bookings of at least $2,000,000, such number of shares of Buyer Common Stock as is equal to the number of Common Shares subject to the unexercised portion of such Warrant immediately prior to the Effective Time multiplied by the Second Earn-out Share Conversion Ratio (with any fraction resulting from such multiplication to be rounded down to the nearest whole number) and plus (iv) if, during the Full Earn-Out Period, the Buyer achieves Bookings of at least $7,000,000, such number of shares of Buyer Common Stock as is equal to the number of Common Shares subject to the unexercised portion of such Warrant immediately prior to the Effective Time multiplied by the Full Earn-out Share Conversion Ratio (with any fraction resulting from such multiplication to be rounded down to the nearest whole number). The exercise price per share of each such assumed Warrant shall be equal to the exercise price of such Warrant immediately prior to the

-5-

Effective Time, divided by the Common Conversion Ratio (rounded up to the nearest whole cent). The term, exercisability, vesting schedule and all of the other terms of the Warrants shall otherwise remain unchanged. In the event any such Warrant is exercised prior to issuance of the Initial Earn-out Shares, the Second Earn-out Shares or the Full Earn-out Shares, as the case may be, the Earn-out Shares issuable to such Warrant holder with respect to the portion of the Warrant so exercised shall be issued to the such Warrant holder at the time of issuance of the Initial Earn-out Shares, the Second Earn-out Shares or the Full Earn-out Shares, as the case may be.

(c) As soon as practicable after the Effective Time, the Buyer or the Surviving Corporation shall deliver to the holders of Options and Warrants appropriate notices setting forth such holders’ rights pursuant to such Options and Warrants, as amended by this Section 1.8, and the agreements evidencing such Options and Warrants shall continue in effect on the same terms and conditions (subject to the amendments provided for in this Section 1.8 and set forth in such notice).

(d) The Buyer shall take all corporate action necessary to reserve for issuance a sufficient number of shares of Buyer Common Stock for delivery upon exercise of the Options and Warrants assumed in accordance with this Section 1.8. Within forty-five (45) days after the Effective Time, the Buyer shall file a Registration Statement on Form S-8 (or any successor form) under the Securities Act with respect to all shares of Buyer Common Stock subject to such Options that may be registered on a Form S-8 (the “Eligible Option Shares”), and shall use its Reasonable Best Efforts to maintain the effectiveness of such Registration Statement for so long as such Options remain outstanding.

(e) The Company shall obtain, prior to the Closing, the consent from each holder of an Option or a Warrant to the amendment of such Option or Warrant pursuant to this Section 1.8 (unless such consent is not required under the terms of the applicable agreement, instrument or plan).

1.9 Escrow.

(a) On the Closing Date, the Buyer shall deliver to the Escrow Agent a certificate (issued in the name of the Escrow Agent or its nominee) representing the Escrow Shares issuable pursuant to Section 1.5, for the purpose of securing the indemnification obligations of the Indemnifying Stockholders set forth in this Agreement. The Escrow Shares shall be held by the Escrow Agent under the Escrow Agreement pursuant to the terms thereof. The Escrow Shares shall be held as a trust fund and shall not be subject to any lien, attachment, trustee process or any other judicial process of any creditor of any party, and shall be held and disbursed solely for the purposes and in accordance with the terms of the Escrow Agreement.

(b) The adoption of this Agreement and the approval of the Merger by the stockholders of the Company shall constitute approval of the Escrow Agreement and of all of the arrangements relating thereto, including the placement of the Escrow Shares in escrow and the appointment of the Indemnification Representatives.

(b) The By-laws of the Surviving Corporation immediately following the Effective Time shall be the same as the By-laws of the Transitory Subsidiary immediately prior to the Effective Time, except that the name of the corporation set forth therein shall be changed to the name of the Company.

1.11 No Further Rights. From and after the Effective Time, no Company Shares shall be deemed to be outstanding, and holders of Certificates shall cease to have any rights with respect thereto, except as provided herein or by law.

1.12 Closing of Transfer Books. At the Effective Time, the stock transfer books of the Company shall be closed and no transfer of Company Shares shall thereafter be made. If, after the Effective Time, Certificates are presented to the Buyer or the Surviving Corporation, they shall be cancelled and exchanged for Initial Shares and Escrow Shares in accordance with Section 1.5 and Section 1.9, and subject to applicable law in the case of Dissenting Shares.

1.13 Additional Consideration.

(a) If, during the Initial Earn-Out Period, the Buyer achieves Bookings of at least $1,500,000, then, subject to the provisions of this Section 1.13, the holder of each Company Share issued and outstanding immediately prior to the Effective Time (other than Company Shares owned beneficially by the Buyer or the Transitory Subsidiary, Dissenting Shares and Company Shares held in the Company’s treasury) shall be entitled to receive such number of additional shares of Buyer Common Stock as is equal to the result obtained by dividing (i) $3,000,000 by (ii) the sum of (A) the number of outstanding Company Shares immediately prior to the Effective Time and (B) the number of Common Shares issuable upon exercise of all Options and Warrants vested or exercisable, as the case may be, immediately prior to the Effective Time, but excluding the Common Shares issuable due to the acceleration of the Retained Employee Double Trigger Options pursuant to Section 4.12, and dividing such amount by (iii) the average of the last reported sale prices per share of the Buyer Common Stock on the Nasdaq National Market over the ten (10) consecutive trading days ending on the trading day that is one (1) trading day prior to the issuance of such Buyer Common Stock (the “Initial Earn-out Share Conversion Ratio”). The Initial Earn-out Share Conversion Ratio shall be subject to equitable adjustment in the event of any stock split, stock dividend, reverse stock split or similar event affecting the Buyer Common Stock between the beginning of such ten-day period and the issuance date.

(b) If, during the Second Earn-Out Period, the Buyer achieves Bookings of at least $2,000,000, then, subject to the provisions of this Section 1.13, the holder of each Company Share issued and outstanding immediately prior to the Effective Time (other than Company Shares owned beneficially by the Buyer or the Transitory Subsidiary, Dissenting Shares and Company Shares held in the Company’s treasury) shall be entitled to receive such number of

-7-

additional shares of Buyer Common Stock as is equal to the result obtained by dividing (i) $1,500,000 by (ii) the sum of (A) the number of outstanding Company Shares immediately prior to the Effective Time and (B) the number of Common Shares issuable upon exercise of all Options and Warrants vested or exercisable, as the case may be, immediately prior to the Effective Time, but excluding the Common Shares issuable due to the acceleration of the Retained Employee Double Trigger Options pursuant to Section 4.12, and dividing such amount by (iii) the average of the last reported sale prices per share of the Buyer Common Stock on the Nasdaq National Market over the ten (10) consecutive trading days ending on the trading day that is one (1) trading day prior to the issuance of such Buyer Common Stock (the “Second Earn-out Share Conversion Ratio”). The Second Earn-out Share Conversion Ratio shall be subject to equitable adjustment in the event of any stock split, stock dividend, reverse stock split or similar event affecting the Buyer Common Stock between the beginning of such ten-day period and the issuance date.

(c) If, during the Full Earn-Out Period, the Buyer achieves Bookings of at least $7,000,000, then, subject to the provisions of this Section 1.13, the holder of each Company Share issued and outstanding immediately prior to the Effective Time (other than Company Shares owned beneficially by the Buyer or the Transitory Subsidiary, Dissenting Shares and Company Shares held in the Company’s treasury) shall be entitled to receive such number of additional shares of Buyer Common Stock as is equal to the result obtained by dividing (i) the Applicable Consideration Amount by (ii) the sum of (A) the number of outstanding Company Shares immediately prior to the Effective Time and (B) the number of Common Shares issuable upon exercise of all Options and Warrants vested or exercisable, as the case may be, immediately prior to the Effective Time, but excluding the Common Shares issuable due to the acceleration of the Retained Employee Double Trigger Options pursuant to Section 4.12, and dividing such amount by (iii) the average of the last reported sale prices per share of the Buyer Common Stock on the Nasdaq National Market over the ten (10) consecutive trading days ending on the trading day that is one (1) trading day prior to the issuance of such Buyer Common Stock (the “Full Earn-out Share Conversion Ratio”). The Full Earn-out Share Conversion Ratio shall be subject to equitable adjustment in the event of any stock split, stock dividend, reverse stock split or similar event affecting the Buyer Common Stock between the beginning of such ten-day period and the issuance date.

(d) No later than (i) April 15, 2004 with respect to the Initial Earn-out Period, (ii) July 15, 2004 with respect to the Second Earn-out Period and (iii) April 15, 2005 with respect to the Full Earn-out Period, Buyer shall prepare (or cause to be prepared) and deliver to the Indemnification Representatives, a calculation of the Bookings for the Initial Earn-out Period, the Second Earn-out Period and the Full Earn-out Period, as the case may be, and a statement of the total number, if any, of the Initial Earn-out Shares, Second Earn-out Shares and the Full Earn-out Shares, as the case may be, issuable based on such Bookings, together with any documentation as may be reasonably necessary to enable the Indemnification Representatives to assess such calculation. After receipt from the Buyer of the calculation of the Bookings for each of the Initial Earn-out Period, the Second Earn-out Period and the Full Earn-out Period, as applicable, the Indemnification Representatives shall have the right, at the expense of the Company Stockholders, and upon not less than ten (10) days’ prior notice to the Buyer, to meet with the Buyer to discuss the Buyer’s calculation and have reasonable access during normal business hours to inspect the records and working papers relating to the calculation of such

-8-

Bookings and in each case solely for the purpose of verifying the calculation of the Bookings hereunder. Unless the Indemnification Representatives challenge the Buyer’s determination of the Bookings within ten (10) days after delivery of the calculation of the Bookings for each of the Initial Earn-out Period, the Second Earn-out Period and the Full Earn-out Period, as applicable, the Buyer’s determination shall be conclusive and binding for all purposes of this Agreement.

(e) In the event that the Indemnification Representatives dispute the Buyer’s determination of the Bookings for the Initial Earn-out Period, the Second Earn-out Period or the Full Earn-out Period, as applicable, or there is a dispute with regard to any other provision of this Section 1.13, the Indemnification Representatives shall so notify the Buyer by delivering an Earn-Out Dispute Notice to the Buyer. With respect to disputes regarding the Buyer’s determination of the Bookings, the Indemnification Representatives shall deliver the Earn-Out Dispute Notice within ten (10) days after delivery by the Buyer of the Bookings calculation for the Initial Earn-out Period, the Second Earn-out Period or the Full Earn-out Period, as applicable. In the event of such a dispute, the Buyer and the Indemnification Representatives shall first use diligent good faith efforts to resolve such dispute among themselves. If they are unable to resolve the dispute within thirty (30) days after the delivery of such Earn-Out Dispute Notice, then the dispute shall be submitted to the Earn-Out Arbitrator for determination in accordance with the Commercial Rules in effect from time to time and the following provisions.

(i) In the event of any conflict between the Commercial Rules in effect from time to time and the provisions of this Agreement, the provisions of this Agreement shall prevail and be controlling.

(ii) Not later than thirty (30) days after the conclusion of the arbitration hearing, the Earn-out Arbitrator shall prepare and distribute to the parties a writing setting forth the Bookings for the applicable period and the Earn-out Arbitrator’s reasons therefor. Any decision rendered by the Earn-out Arbitrator shall be final, conclusive and binding upon the parties, and judgment thereon may be entered and enforced in any court of competent jurisdiction (subject to Section 10.11).

(iii) The Earn-out Arbitrator shall have no power or authority, under the Commercial Rules or otherwise, to (x) modify or disregard any provision of this Agreement, including the provisions of this Section 1.13(e), or (y) address or resolve any issue not submitted by the parties.

(iv) The fees and expenses of the Earn-Out Arbitrator in connection with the resolutions of disputes pursuant to this paragraph (e) shall be shared equally by the Company Stockholders on the one hand and the Buyer on the other, provided that, if the Earn-Out Arbitrator determines that one party has adopted a position(s) that is frivolous or clearly without merit, the Earn-Out Arbitrator may, in its discretion, assign a greater portion of such fees and expenses to such party.

(f) In order to support and facilitate the attainment of Bookings, the Buyer agrees, through the term of the Full Earn-out Period, to maintain four (4) fully dedicated sales personnel (provided, however that through March 31, 2004 the Buyer shall maintain five (5)

fully dedicated sales personnel) and that 16 of the Buyer’s other sales personnel will be trained, at least once a calendar quarter, to sell the Products and Services. All of the Buyer’s sales personnel shall be compensated on the same basis for the sale of the Products and Services as such personnel are compensated for the sale of the Buyer’s other products and services. Buyer agrees that the price for the sale by the Buyer or any of its Affiliates of any single node of the Products and Services shall be at a price of at least $1,000. All sales of Products and Services for more than a single node shall be sold with discounts off of list price that are consistent with the discounts off of list price offered by the Buyer in the sales of its other similar products and services. Buyer shall offer the Products and Services to potential partners for redistribution at substantially similar pricing discounts as it offers its other similar products to these partners. In the event Buyer is in material breach of any of the covenants set forth in this Section 1.13(f) and does not cure such breach within thirty (30) days after notice from the Indemnification Representatives, the Buyer shall issue to the Company Stockholders all of the Earn-Out Shares issuable with respect to those Earn-out Periods that have not expired as of the date of such material breach.

(h) The applicable Earn-out Shares shall be issued within five (5) days after (i) the expiration of the ten (10) day period for giving an Earn-out Dispute Notice, if no Earn-out Dispute Notice is given, or (ii) the resolution of the applicable Earn-out Dispute pursuant to this Section 1.13.

(i) No certificates or scrip representing fractional Earn-out Shares shall be issued to Company Stockholders, and such Company Stockholders shall not be entitled to any voting rights, rights to receive any dividends or distributions or other rights as a stockholder of the Buyer with respect to any fractional Earn-out Shares that would have otherwise been issued to such Company Stockholders. In lieu of any fractional Earn-out Shares that would have otherwise been issued, each Company Stockholder that would have been entitled to receive a fractional Earn-out Share shall receive a cash payment equal to the closing price per share of the Buyer Common Stock on the Nasdaq National Market, as reported by Nasdaq, on the business day immediately preceding the issuance of such Earn-out Share, multiplied by the fraction of a share that such Company Stockholder would otherwise be entitled to receive. In the event the Buyer is acquired prior to the expiration of the Full Earn-out Period, then after the date of any such acquisition, in lieu of receiving shares of Buyer Common Stock under this Section 1.13, the Company Stockholders shall be entitled to receive as consideration, to the extent Earn-Out Shares are earned hereunder, the kind and amount of securities, cash or other property which the Company Stockholders would have been entitled to receive pursuant to such acquisition if such Earn-out Shares had been issued immediately prior to such acquisition, which consideration, in the case of securities, shall be subject to equitable adjustment in the event of any stock split, stock dividend, reverse stock split or similar event affecting such securities between the date of such acquisition and the issuance date.

Without limitation of the foregoing, the Surviving Corporation shall deduct and withhold the Tax imposed by Section 4999 of the Code on excess parachute payments in the event the required stockholder vote referred to in Section 4.14 of this Agreement is not successfully obtained.

For this purpose, Taxes attributable to a taxable period beginning before and ending after the Closing Date shall be allocable to the portion of such period ending on the Closing Date to the extent (x) in the case of Taxes that (A) are based upon or related to income or receipts or (B) imposed in connection with any sale or other transfer or assignment of property, other than the Taxes described in Section 6.1(f), of the amount of such Taxes that would be payable if the taxable year ended with the Closing Date, and (y) in the case of other Taxes imposed on a periodic basis (including property Taxes), the amount of such Taxes for the entire tax period multiplied by a fraction, the numerator of which is the number of calendar days in the period ending with the Closing Date and the denominator of which is the number of calendar days in the entire period;

6.3 Indemnification Claims.

(a) An Indemnified Party shall give written notification to the Indemnifying Party of the commencement of any Third Party Action. Such notification shall be given within fifteen (15) days after receipt by the Indemnified Party of notice of such Third Party Action, and shall describe in reasonable detail (to the extent known by the Indemnified Party) the facts constituting the basis for such Third Party Action and the amount of the claimed damages; provided, however, that no delay or failure on the part of the Indemnified Party in so notifying the Indemnifying Party shall relieve the Indemnifying Party of any liability or obligation hereunder except to the extent of any damage or liability caused by or arising out of such failure. Within fifteen (15) days after delivery of such notification, the Indemnifying Party may, upon written notice thereof to the Indemnified Party, assume control of the defense of such Third Party Action with counsel reasonably satisfactory to the Indemnified Party; provided that (i) the Indemnifying Party may only assume control of such defense if (A) it acknowledges in writing to the Indemnified Party that any damages, fines, costs or other liabilities that may be assessed against the Indemnified Party in connection with such Third Party Action constitute Damages for

-40-

which the Indemnified Party shall be indemnified pursuant to this Article VI and (B) the ad damnum is less than or equal to the amount of Damages for which the Indemnifying Party is liable under this Article VI and (ii) the Indemnifying Party may not assume control of the defense of Third Party Action involving criminal liability or in which equitable relief is sought against the Indemnified Party. If the Indemnifying Party does not, or is not permitted under the terms hereof to, so assume control of the defense of a Third Party Action, the Indemnified Party shall control such defense. The Non-controlling Party may participate in such defense at its own expense. The Controlling Party shall keep the Non-controlling Party advised of the status of such Third Party Action and the defense thereof and shall consider in good faith recommendations made by the Non-controlling Party with respect thereto. The Non-controlling Party shall furnish the Controlling Party with such information as it may have with respect to such Third Party Action (including copies of any summons, complaint or other pleading which may have been served on such party and any written claim, demand, invoice, billing or other document evidencing or asserting the same) and shall otherwise cooperate with and assist the Controlling Party in the defense of such Third Party Action. The fees and expenses of counsel to the Indemnified Party with respect to a Third Party Action shall be considered Damages for purposes of this Agreement if (i) the Indemnified Party controls the defense of such Third Party Action pursuant to the terms of this Section 6.3(a) or (ii) the Indemnifying Party assumes control of such defense and the Indemnified Party reasonably concludes that the Indemnifying Party and the Indemnified Party have conflicting interests or different defenses available with respect to such Third Party Action. Except as set forth in the foregoing sentence, the Indemnifying Party shall not be liable to the Indemnified Party for the fees and expenses of counsel to the Indemnified Party in connection with the defense of any Third Party Action. The Indemnifying Party shall not agree to any settlement of, or the entry of any judgment arising from, any Third Party Action without the prior written consent of the Indemnified Party, which shall not be unreasonably withheld, conditioned or delayed. The Indemnified Party shall not agree to any settlement of, or the entry of any judgment arising from, any such Third Party Action without the prior written consent of the Indemnifying Party, which shall not be unreasonably withheld, conditioned or delayed.

(b) In order to seek indemnification under this Article VI, an Indemnified Party shall deliver a Claim Notice to the Indemnifying Party. If the Indemnified Party is the Buyer, the Indemnifying Party shall deliver a copy of the Claim Notice to the Escrow Agent.

(c) Within fifteen (15) days after delivery of a Claim Notice, the Indemnifying Party shall deliver to the Indemnified Party a Response, in which the Indemnifying Party shall: (i) agree that the Indemnified Party is entitled to receive all of the Claimed Amount (in which case the Response shall be accompanied by a payment by the Indemnifying Party to the Indemnified Party of the Claimed Amount, by check or by wire transfer; provided that if the Indemnified Party is the Buyer, the Indemnifying Party and the Indemnified Party shall deliver to the Escrow Agent, within three (3) business days following the delivery of the Response, a written notice executed by both parties instructing the Escrow Agent to distribute to the Buyer such number of Escrow Shares as have an aggregate Value equal to the Claimed Amount), (ii) agree that the Indemnified Party is entitled to receive the Agreed Amount (in which case the Response shall be accompanied by a payment by the Indemnifying Party to the Indemnified Party of the Agreed Amount, by check or by wire transfer; provided that if the Indemnified Party is the Buyer, the Indemnifying Party and the Indemnified Party shall deliver to the Escrow

-41-

Agent, within three (3) business days following the delivery of the Response, a written notice executed by both parties instructing the Escrow Agent to distribute to the Buyer such number of Escrow Shares as have an aggregate Value equal to the Agreed Amount) or (iii) dispute that the Indemnified Party is entitled to receive any of the Claimed Amount. For purposes of this Article VI, the “Value” of any Escrow Shares delivered in satisfaction of an indemnity claim shall be the average of the last reported sale prices per share of the Buyer Common Stock on the Nasdaq National Market over the ten consecutive trading days ending on the trading day that is one (1) trading day prior to the Closing Date (subject to equitable adjustment in the event of any stock split, stock dividend, reverse stock split or similar event affecting the Buyer Common Stock since the beginning of such ten-day period), multiplied by the number of such Escrow Shares.

(d) During the 30-day period following the delivery of a Response that reflects a Dispute, the Indemnifying Party and the Indemnified Party shall use good faith efforts to resolve the Dispute. If the Dispute is not resolved within such 30-day period, the Indemnifying Party and the Indemnified Party shall discuss in good faith the submission of the Dispute to binding arbitration, and if the Indemnifying Party and the Indemnified Party agree in writing to submit the Dispute to such arbitration, then the provisions of Section 6.3(e) shall become effective with respect to such Dispute. The provisions of this Section 6.3(d) shall not obligate the Indemnifying Party and the Indemnified Party to submit to arbitration or any other alternative dispute resolution procedure with respect to any Dispute, and in the absence of an agreement by the Indemnifying Party and the Indemnified Party to arbitrate a Dispute, such Dispute shall be resolved in a state or federal court sitting in New Castle County, Delaware, in accordance with Section 10.11. If the Indemnified Party is the Buyer and is seeking to enforce the claim that is the subject of the Dispute pursuant to the Escrow Agreement, the Indemnifying Party and the Indemnified Party shall deliver to the Escrow Agent, promptly following the resolution of the Dispute (whether by mutual agreement, arbitration, judicial decision or otherwise), a written notice executed by both parties instructing the Escrow Agent as to what (if any) portion of the Escrow Shares shall be distributed to the Buyer and/or the Indemnifying Stockholders (which notice shall be consistent with the terms of the resolution of the Dispute).

(e) If, as set forth in Section 6.3(d), the Indemnified Party and the Indemnifying Party agree to submit any Dispute to binding arbitration, the arbitration shall be conducted by a single arbitrator (the “Arbitrator”) in accordance with the Commercial Rules in effect from time to time and the following provisions:

(i) In the event of any conflict between the Commercial Rules in effect from time to time and the provisions of this Agreement, the provisions of this Agreement shall prevail and be controlling.

(ii) The parties shall commence the arbitration by jointly filing a written submission with the New Castle County, Delaware office of the AAA in accordance with Commercial Rule 5 (or any successor provision).

(iii) Not later than thirty (30) days after the conclusion of the arbitration hearing, the Arbitrator shall prepare and distribute to the parties a writing setting forth the arbitral award and the Arbitrator’s reasons therefor. Any award rendered by the Arbitrator

-42-

shall be final, conclusive and binding upon the parties, and judgment thereon may be entered and enforced in any court of competent jurisdiction (subject to Section 10.11), provided that the Arbitrator shall have no power or authority to grant injunctive relief, specific performance or other equitable relief.

(iv) The Arbitrator shall have no power or authority, under the Commercial Rules or otherwise, to (x) modify or disregard any provision of this Agreement, including the provisions of this Section 6.3(e), or (y) address or resolve any issue not submitted by the parties.

(v) In connection with any arbitration proceeding pursuant to this Agreement, each party shall bear its own costs and expenses, except that the fees and costs of the AAA and the Arbitrator, the costs and expenses of obtaining the facility where the arbitration hearing is held, and such other costs and expenses as the Arbitrator may determine to be directly related to the conduct of the arbitration and appropriately borne jointly by the parties (which shall not include any party’s attorneys’ fees or costs, witness fees (if any), costs of investigation and similar expenses) shall be shared equally by the Indemnified Party and the Indemnifying Party.

(f) Notwithstanding the other provisions of this Section 6.3, if a third party asserts (other than by means of a lawsuit) that an Indemnified Party is liable to such third party for a monetary or other obligation which may constitute or result in Damages for which such Indemnified Party may be entitled to indemnification pursuant to this Article VI, and such Indemnified Party reasonably determines that it has a substantial business reason to fulfill such obligation, then (i) such Indemnified Party shall be entitled to satisfy such obligation, without prior notice to or consent from the Indemnifying Party, (ii) such Indemnified Party may subsequently make a claim for indemnification in accordance with the provisions of this Article VI, and (iii) such Indemnified Party shall be reimbursed, in accordance with the provisions of this Article VI, for any such Damages for which it is entitled to indemnification pursuant to this Article VI (subject to the right of the Indemnifying Party to dispute the Indemnified Party’s entitlement to indemnification, or the amount for which it is entitled to indemnification, under the terms of this Article VI).

(g) For purposes of this Section 6.3 and the second and third sentences of Section 6.4, (i) if the Indemnifying Stockholders comprise the Indemnifying Party, any references to the Indemnifying Party (except provisions relating to an obligation to make any payments) shall be deemed to refer to the Indemnification Representatives, and (ii) if the Indemnifying Stockholders comprise the Indemnified Party, any references to the Indemnified Party (except provisions relating to an obligation to make or a right to receive any payments) shall be deemed to refer to the Indemnification Representatives.

Without limiting the generality of the foregoing, the Company Stockholders, by virtue of their approval of this Agreement, for themselves and their respective heirs, executors, administrators, successors and assigns, hereby authorize the Indemnification Representatives to: (i) give and receive notices and communications pursuant to this Agreement, the Escrow Agreement, and the other transaction documents and to make and receive service of process in any legal action or proceeding arising out of or related to this Agreement, the Escrow Agreement, or the other transaction documents or any of the transactions contemplated hereunder or thereunder, (ii) agree to, negotiate, enter into settlements and compromises of, and demand dispute resolution with respect to any dispute, claim, action, suit or proceeding arising out of this Agreement, the Escrow Agreement, or the other transaction documents, including, without limitation, pursuant to Section 1.13 and this Article VI, and to comply with orders of courts and awards of arbitrators with respect to such claims, (iii) effect any amendment to this Agreement, the Escrow Agreement, or the other transaction documents that the Indemnification Representatives deem necessary or desirable (provided that any such amendment does not adversely prejudice the rights of the Indemnifying Stockholders in general or an Indemnifying Stockholder in particular), (iv) execute and deliver on their behalf all documents and instruments which may be executed and delivered pursuant to this Agreement, the Escrow Agreement, or the other transaction documents (except for letters of transmittal and stock powers), (v) appoint or provide for successor Indemnification Representatives, and (vi) take all actions necessary or appropriate in the judgment of the Indemnification Representatives for the accomplishment of the foregoing. Such agency of the Indemnification Representatives may be changed by the Company Stockholders from time to time upon not less than 30 days’ prior written notice to Buyer and the Escrow Agent; provided that the Indemnification Representatives may not be removed unless holders of a majority in interest of the Escrow Shares agree to such removal and to the identity of the substituted Indemnification Representatives. The Indemnification Representatives shall not be responsible for any act done or omitted thereunder as Indemnification Representatives unless such action or omission results from or arises out of fraud, gross negligence, bad faith, or willful misconduct on the part of the Indemnification Representatives. The Company Stockholders shall severally indemnify the Indemnification Representatives and hold the Indemnification Representatives harmless against any loss, liability, or expense incurred without fraud, gross negligence, bad faith, or willful misconduct on the part of the Indemnification Representatives and arising out of or in connection with the acceptance or administration of the Indemnification Representatives’ duties hereunder, including the reasonable fees and expenses of any legal counsel or other professional retained by the Indemnification Representatives. Each Company Stockholder hereby agrees to pay all costs and expenses, including those of any legal counsel or other professional retained by the Indemnification Representatives, in connection with the acceptance or administration of the Indemnification Representatives’ duties hereunder. A decision, act, consent, or instruction of the Indemnification Representatives shall constitute a decision of all the Company Stockholders, and shall be final, binding and conclusive upon each of the Company Stockholders, and the Escrow Agent and the Buyer may rely upon any decision, act, consent or instruction of the Indemnification Representatives as being the decision, act, consent or instruction of each and all

-44-

of the Company Stockholders. The Escrow Agent and the Buyer are hereby relieved from any liability to any person for any acts done by them in accordance with such decision, act, consent or instruction of the Indemnification Representatives.

All representations and warranties that are covered by the indemnification agreements in Section 6.1(a) and Section 6.2(a) shall (a) survive the Closing and (b) shall expire on the date fifteen (15) months following the Closing Date. If an Indemnified Party delivers to an Indemnifying Party, before expiration of a representation or warranty, either a Claim Notice based upon a breach of such representation or warranty, or an Expected Claim Notice based upon a breach of such representation or warranty, then the applicable representation or warranty shall survive until, but only for purposes of, the resolution of the matter covered by such notice. If the legal proceeding or written claim with respect to which an Expected Claim Notice has been given is definitively withdrawn or resolved in favor of the Indemnified Party, the Indemnified Party shall promptly so notify the Indemnifying Party; and if the Indemnified Party has delivered a copy of the Expected Claim Notice to the Escrow Agent and Escrow Shares have been retained in escrow after the Termination Date (as defined in the Escrow Agreement) with respect to such Expected Claim Notice, the Indemnifying Party and the Indemnified Party shall promptly deliver to the Escrow Agent a written notice executed by both parties instructing the Escrow Agent to distribute such retained Escrow Shares to the Indemnifying Stockholders in accordance with the terms of the Escrow Agreement.

(c) Except with respect to claims based on an intent to deceive or to defraud, and except as otherwise provided in Section 6.5(d) with respect to a claim based on the Section 6.1(i) Matters, (i) the Escrow Agreement shall be the sole and exclusive means for the Buyer to collect any Damages for which it is entitled to indemnification under this Article VI, (ii) the aggregate liability of the Buyer for Damages under this Article VI shall not exceed $3,100,000, (iii) after the Closing, the rights of indemnification of the Indemnified Parties under this Article VI and the Escrow Agreement shall be the sole and exclusive remedy of the Indemnified Parties with respect to any and all claims resulting from or relating to any misrepresentation, breach of warranty or failure to perform any covenant or agreement contained in this Agreement and (iv) and any such claim can only be made within the fifteen (15) month period following the Closing Date. Without limitation of the foregoing, effective as of the Closing, the Buyer and its Affiliates hereby waive and release, to the fullest extent provided by law, any other claim the Buyer or any Affiliate may have against any Company Stockholder relating to the subject matter of this Article VI. With respect to claims based on an intent to deceive or to defraud the aggregate liability of the Indemnifying Stockholders shall not exceed $31,000,000 plus (x) the Value, as of the date of issuance, of any Earn-out Shares issued to the Indemnifying Stockholders pursuant to Section 1.13 of this Agreement and minus (y) the Value of any Escrow Shares previously distributed to Buyer in connection with an indemnification obligation under this Article VI.

(d) Notwithstanding the provisions of Section 6.5(c)(i), Section 6.5(c)(ii) and Section 6.5(c)(iv), with respect to any claim relating to the Section 6.1(i) Matters (i) following the termination of the Escrow Agreement, but subject to clause (iii) below, the Escrow Agreement shall not be the sole and exclusive means for the Buyer to collect any Damages for which it is entitled to indemnification under Section 6.1(i), (ii) the liability of the Indemnifying Stockholders for claims with respect to the Section 6.1(i) Matters shall not exceed $3,000,000 and (iii) the Buyer may make claims with respect to the Section 6.1(i) Matters for a period of three (3) years after the Closing.

(f) The amount of Damages recoverable by an Indemnified Party under this Article VI with respect to an indemnity claim shall be reduced by any proceeds actually received by such Indemnified Party or an Affiliate, with respect to the Damages to which such indemnity claim relates, from an insurance carrier; provided, however, that the Indemnifying Party shall not be required to seek any such insurance recovery.

-46-

(g) The representations and warranties (and, if applicable, the related Disclosure Schedule) set forth in this Agreement are the sole and exclusive representations and warranties made by the Parties in connection with the transactions contemplated hereby and no Party shall be deemed to have made any representation or warranty other than as expressly made in this Agreement. Without limiting the foregoing, no Party makes any representation or warranty with respect to any information or documents made available to any other Party, or its or their counsel, accountants, advisors or representatives except for the express representations and warranties made in this Agreement (and, if applicable, the related Disclosure Schedule).

6.6 Treatment of Indemnity Payments. Any payments made to an Indemnified Party pursuant to this Article VI or pursuant to the Escrow Agreement shall be treated as an adjustment to the Merger Consideration for Tax purposes.
