                This VOTING AND TENDER AGREEMENT (this “Agreement”), is made and entered into as of December 19, 2005, by and among Progress Software Corporation, a Massachusetts corporation (“Parent”), Noble Acquisition Corp., a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”), and the undersigned stockholder (“Stockholder”) of NEON Systems, Inc., a Delaware corporation (the “Company”).

RECITALS

                A.            Concurrently with the execution of this Agreement, Parent, Merger Sub and the Company are entering into an Agreement and Plan of Merger (the “Merger Agreement”) pursuant to which Merger Sub has agreed to make a tender offer (the “Offer”) for all outstanding shares of common stock, par value $0.01 per share, of the Company (“Company Common Stock”) at a price per share of $6.20, net to the seller in cash and subject to adjustment as set forth in the Merger Agreement (the “Offer Price”), such tender offer to be followed by the merger of Merger Sub with and into the Company (the “Merger”).  Capitalized terms used but not defined herein shall have the meanings given to them in the Merger Agreement.

                B.            Stockholder is the record holder of such number of outstanding shares of Company Common Stock as is indicated on the signature pages to this Agreement.

                C.            As a material inducement to enter into the Merger Agreement, Parent and Merger Sub desire Stockholder to agree, and Stockholder is willing to agree, to vote and tender the Shares (as defined in Section 1.1 below), and such other shares of capital stock of the Company over which Stockholder has voting power, so as to facilitate consummation of the Offer and the Merger.

                In consideration of the foregoing and the representations, warranties, covenants and agreements set forth in this Agreement, the parties agree as follows:

1.          Tender and Voting of Shares.

1.1           Shares.  The term “Shares” shall mean all issued and outstanding shares of Company Common Stock owned of record and beneficially owned by Stockholder or over which Stockholder exercises sole voting power, in each case, as of the date of this Agreement.  Stockholder agrees that any shares of capital stock of the Company that Stockholder purchases or with respect to which Stockholder otherwise acquires beneficial ownership or over which Stockholder exercises sole voting power after the date of this Agreement and prior to the termination of this Agreement pursuant to Section 4 below shall be subject to the terms and conditions of this Agreement to the same extent as if they constituted Shares as of the date hereof.

1.2           Agreement to Tender Shares.  Stockholder hereby covenants and agrees to tender and, subject to the satisfaction of the Minimum Condition, to sell to Merger Sub, not later than one (1) business day prior to the initial expiration date of the Offer, without regard to any

extension thereof (the “Initial Expiration Date”), all the Shares, pursuant to and in accordance with the Offer and this Agreement.  Stockholder agrees that Stockholder shall deliver or cause to be delivered to the depositary for the Offer, not later than one (1) business day before the Initial Expiration Date of the Offer, either a letter of transmittal together with the certificates for the Shares, if available, or a “Notice of Guaranteed Delivery”, if the certificates for the Shares are not available.  After such tender Stockholder shall not withdraw any such Shares, until this Agreement is terminated in accordance with its terms.  Stockholder further agrees not to enter into any agreement or understanding with any person the effect of which would be inconsistent with or violative or any provision contained in this Section 1.2.

1.3           Agreement to Vote Shares.  Stockholder hereby covenants and agrees that during the period commencing on the date hereof and continuing until this Agreement terminates pursuant to Section 4 hereof, at any meeting (whether annual or special and whether or not an adjourned or postponed meeting) of the stockholders of the Company, however called, and in any action by written consent of the stockholders of the Company, Stockholder shall appear at the meeting or otherwise cause any and all Shares to be counted as present thereat for purposes of establishing a quorum and vote (or cause to be voted) any and all Shares:  (i) in favor of the approval and adoption of the Merger Agreement and the approval of the Merger; and (ii) against any Acquisition Proposal or Superior Offer.  Stockholder further agrees not to enter into any agreement or understanding with any person the effect of which would be inconsistent with or violative of any provision contained in this Section 1.3.

1.4           Irrevocable Proxy.  Concurrently with the execution of this Agreement, Stockholder agrees to deliver to Parent a proxy in the form attached hereto as Exhibit I (the “Proxy”), which shall be irrevocable, with respect to the Shares, subject to the other terms of this Agreement.

1.5           Adjustments Upon Changes in Capitalization.  In the event of any change in the number of issued and outstanding shares of Company Common Stock by reason of any stock split, reverse split, stock dividend (including any dividend or distribution of securities convertible into Company Common Stock), combination, reorganization, recapitalization or other like change, conversion or exchange of shares, or any other change in the corporate or capital structure of the Company, the term “Shares” shall be deemed to refer to and include the Shares as well as all such stock dividends and distributions and any shares into which or for which any or all of the Shares may be changed or exchanged.

2

2.             Transfer and Other Restrictions.  Stockholder represents, covenants and agrees that, except for the proxy granted in Section 1.4 hereof and as contemplated by this Agreement:  (i) Stockholder shall not, directly or indirectly, during the period commencing on the date hereof and continuing until this Agreement terminates pursuant to Section 4 hereof, offer for sale or agree to sell, transfer, tender, assign, pledge, hypothecate or otherwise dispose of or enter into any contract, option or other arrangement or understanding with respect to, or consent to, the offer for sale, sale, transfer, tender, pledge, hypothecation, encumbrance, assignment or other disposition of, or create any Encumbrance of any nature whatsoever with respect to any or all of the Shares or any interest thereon; (ii) Stockholder shall not grant any proxy, irrevocable proxy or power of attorney or deposit any Shares into a voting trust or enter into a voting agreement or arrangement with respect to the voting of Shares (each a “Voting Proxy”) to any person except as provided by this Agreement; and (iii) Stockholder has granted no Voting Proxy which is currently (or which will hereafter become) effective with respect to the Shares, and if any Voting Proxy has been granted to any person, such Voting Proxy is hereby revoked.  Notwithstanding the foregoing, Stockholder may transfer any Shares as a bona fide gift or gifts, provided that it shall be a condition to such transfer that each donee thereof executes and delivers to Parent (A) an agreement with Parent and Merger Sub in the form of this Agreement and (B) an irrevocable proxy in the form attached hereto as Exhibit I, in each case with respect to any and all Shares so transferred.

3

contemplated hereby.  There is no beneficiary or holder of a voting trust certificate or other interest of any trust of which Stockholder is settlor or trustee or any other person or Governmental Entity whose consent, approval, order or authorization is required by or with respect to Stockholder for the execution, delivery and performance of this Agreement by Stockholder or the consummation by Stockholder of the transactions contemplated hereby.

3.3           Title.  Stockholder is the record owner of the shares of Company Common Stock indicated on the signature pages hereto, which, on and as of the date hereof, are free and clear of any Encumbrances that would adversely affect the ability of Stockholder to carry out the terms of this Agreement.  The number of Shares set forth on the signature pages hereto are the only Shares owned of record or beneficially owned by Stockholder or over which Stockholder exercises voting power and, except as set forth on such signature pages, Stockholder holds no options or warrants to purchase or rights to subscribe for or otherwise acquire any securities of the Company and has no other interest in or voting rights with respect to any securities of the Company.

4.             Effectiveness; Termination; No Survival.  This Agreement shall become effective upon its execution by Stockholder, Parent and Merger Sub and upon the execution of the Merger Agreement.  This Agreement may be terminated at any time by mutual written consent of Stockholder, Parent and Merger Sub.  This Agreement, and the obligations of Stockholder hereunder, including, without limitation, Stockholder’s obligations under Section 1 and Section 2 above, shall terminate, without any action by the parties hereto, upon the earliest to occur of the following: (i) such date and time as the Merger shall become effective in accordance with the terms and provisions of the Merger Agreement; (ii) such date and time as Merger Sub accepts for payment all of the Shares held by Stockholder; (iii) such date and time as the Merger Agreement has been amended by the parties thereto to lower or change the form of consideration set forth in the Offer Price; and (iv) such date and time as the Merger Agreement shall have been validly terminated pursuant to Article 8 thereof.
