Burrow, acting as the shareholder representative for the Significant PEI Shareholders (the "Shareholder Representative"), and Johnny J. Williams (the "Escrow Agent"). RECITALS: -------- A. Parent, Purchaser, IDS Engineering Management, LC, a Texas limited liability company, and Petrocon Engineering Inc., a Texas corporation ("PEI"), entered into a Merger Agreement on or about July 31, 2001 (the "Merger Agreement"). B. The Merger Agreement provides that each outstanding and unexercised PEI stock option and warrant that represents a right to acquire securities in PEI shall be assumed by Parent and converted into an option or warrant, as the case may be (together, the "Surviving Options"), to purchase shares of Parent common stock, par value $.001 per share (the "Common Stock"), in an amount and at an exercise price set forth in the Merger Agreement. C. The Merger Agreement further provides that the Significant PEI Shareholders are to deposit the number of shares of Common Stock equal to the number of shares issuable on the exercise of the Surviving Options (the "Escrow Shares"), into an escrow created by this Agreement, which shall be a fund to satisfy the obligations under the Surviving Options pursuant to the Merger Agreement. D. Pursuant to the terms of the Merger Agreement, upon the exercise of any Surviving Option, the Parent shall deliver the aggregate exercise price (less any amount required to be paid in by Parent for social security and Medicare taxes as a result of such exercise) received by Parent (the "Consideration") to the Escrow Agent for deposit into an escrow created by this Agreement. E. This Agreement, together with the Merger Agreement, shall govern the terms upon which Escrow Agent may distribute the Escrow Shares to holders of the Surviving Options (the "Surviving Option Holders") and to the Significant PEI Shareholders. Capitalized terms used in this Agreement but not defined herein shall have the definition ascribed to them in the Merger Agreement. NOW, THEREFORE, in consideration of the promises contained herein and in the Merger Agreement and other good and valuable consideration, the receipt of which is hereby acknowledged, the parties hereto agree as follows: 1 AGREEMENT: 1. Appointment of Escrow Agent; Delivery of Escrow Shares; Delivery of ------------------------------------------------------------------- Exercise Price. Each of the Parent, Purchaser, and the Shareholder -------------- Representative hereby appoints Johnny J. Williams as Escrow Agent, and Escrow Agent hereby accepts such appointment. Immediately after the Closing, the Shareholder Representative shall deliver or cause to be delivered to Escrow Agent original share certificates registered in the name of the Shareholder Representative as agent for the Significant PEI Shareholders, and representing the Escrow Shares, together with a fully executed blank stock power bearing the name of Escrow Agent as the transferee. Upon the exercise of any Surviving Option after the Closing, the Parent shall deliver the Consideration to the Escrow Agent. 2. Parent's Claim Certificates. Parent, from time to time on or prior to --------------------------- the expiration of the Surviving Options, may make a claim to some or all of the Escrow Shares (the "Parent's Claim") by delivering to Escrow Agent a certificate (the "Parent's Claim Certificate") signed by the president or a vice president of Parent stating: (a) That a Surviving Option Holder has exercised a Surviving Option; (b) The amount of Consideration received by Parent from the Surviving Option Holder, and that such Consideration has been delivered to the Escrow Agent; (c) The amount of the Parent's Claim (rounded to the nearest whole share), which shall be a number of Escrow Shares equal to the number of shares issuable upon the exercise of the Surviving Option; (d) That, upon payment of the Parent's Claim, the Parent shall cancel a number of Escrow Shares equal to the amount of the Parent's Claim; and (e) That Parent has delivered a copy of such Parent's Claim Certificate to the Shareholder Representative and the date on which such copy was delivered. 3.

Any claim which is disputed or objected to by the Shareholder Representative shall, to the extent of such dispute or objection, constitute a "Disputed Claim." 4. Distribution of Escrow Shares. ----------------------------- (a) If Escrow Agent receives from the Shareholder Representative written notice of consent or agreement to all or part of a Parent's Claim, or fails to receive a timely Shareholder Representative's Objection Notice, Escrow Agent shall thereupon promptly: (1) deliver to Parent from the Escrow Shares a share certificate or certificates representing a number of shares equal to the amount of such Parent's Claim. (2) deliver the Consideration to each Significant PEI Shareholder based on their Pro Rata Share (as hereinafter defined); provided however that if any Significant PEI Shareholder's Pro Rata Share of the Consideration is less than $500, the Escrow Agent may hold such funds in escrow, in a non-interest bearing account, until the amount of the disbursements due to such Significant PEI Shareholders aggregate at least $500. (b) If the Escrow Shares are not sufficient to satisfy in full any obligations to Parent under the preceding Section 4(a), Escrow Agent shall deliver to Parent such Escrow Shares as are available. 5. Shareholder Representative's Claim Certificates. The Shareholder ----------------------------------------------- Representative, upon the expiration of any Surviving Options, may make a claim to some or all of the Escrow Shares (the "Shareholder Representative's Claim") by delivering to Escrow Agent a certificate (the "Shareholder Representative's Claim Certificate") signed by the Shareholder Representative stating: (a) That a Surviving Option has expired; (b) The amount of the Shareholder Representative's Claim (rounded to the nearest whole share), which shall be a number of Escrow Shares equal to the number of shares that would otherwise have been issued upon exercise of the expired Surviving Option; and (c) That the Shareholder Representative has delivered a copy of such Shareholder Representative's Claim Certificate to the Parent and the date on which such copy was delivered. 6.

Payment of Shareholder Representative's Claims. ---------------------------------------------- (a) If Escrow Agent receives from the Parent written notice of consent or agreement to all or part of a Shareholder Representative's Claim, or fails to receive a timely Parent's Objection Notice, Escrow Agent shall thereupon promptly deliver to the Significant PEI Shareholders the number of shares equal to their Pro Rata Share (as hereinafter defined); provided however that if any Significant PEI Shareholder's Pro Rata Share of such shares is less than 500 shares, the Escrow Agent may hold such shares in escrow until the aggregate number of undisbursed shares attributable to such Significant PEI Shareholders' Pro Rata Share (together with any other undisbursed shares attributable to such Significant PEI Shareholder's Pro Rata Share) is 500 or more shares. (b) If the Escrow Shares are not sufficient to pay in full any amounts payable to the Significant PEI Shareholders under Section 7(a), Escrow Agent shall pay to Significant PEI Shareholders such Escrow Shares as are available. 8. Distribution of Escrow Shares. ----------------------------- (a) Escrow Agent shall not make any distribution of Escrow Shares with respect to any Parent's Claim or Shareholder Representative's Claim until: (1) it receives the written consent or agreement of the Parent or the Shareholder Representative, as the case may be, with respect to such distribution, or fails to receive a timely Shareholder Representative's Objection Notice or Parent's Objection Notice; or (2) there is a Final Decision with respect to a Disputed Claim. "Final Decision" means a decision, order, judgment or decree of an arbitrator or court having jurisdiction which is either not subject to appeal or as to which notice of appeal has not been timely filed or served. (b) In addition to the foregoing, Parent, Purchaser, Escrow Agent and the Shareholder Representative agree that at any time and from time to time, Parent shall be authorized, upon the joint written request of the Shareholder Representative and a Surviving Option Holder and within five days of such request, to issue to such Surviving Option Holder the number of shares of Common Stock specified by the Shareholder Representative and such Surviving Option Holder (which number may be zero) in such request (the "Requested Shares"), provided that contemporaneous with such written request: -------- (1) the Surviving Option is thereby canceled; 4 (2) the Escrow Agent surrenders to Parent for cancellation a number of shares of Common Stock equal to the number of shares that the Shareholder Representative and such Surviving Option Holder have requested Parent to issue in such request; (3) the number of Escrow Shares remaining would be equal to or greater than the aggregate number of shares issuable upon exercise of all then outstanding Surviving Options. (c) Promptly following the issuance of any Requested Shares, the Escrow Agent shall issue to the Significant PEI Shareholders the number of Escrow Shares equal to the difference between the total number of shares issuable upon the exercise of the Surviving Option canceled in connection with the issuance of the Requested Shares (regardless of whether such shares were vested) and the number of Requested Shares. 9. Adjustments to Escrow Shares; Dividends; Voting. ----------------------------------------------- (a) If Parent or any Significant PEI Shareholder is entitled to receive any securities or other distributions in respect of or in exchange for any of the Escrow Shares (other than dividends declared by the Board of Directors of Parent on the Escrow Shares that are payable in cash), whether by way of stock dividends, share splits, recapitalizations, liquidations, mergers, consolidations, split-ups, spin-offs, redemptions, exchanges or conversions of shares and the like ("New Shares"), such Significant PEI Shareholder shall deliver share certificates representing such New Shares and such other distributions (registered in the name of the Shareholder Representative as agent for such Significant PEI Shareholder) to Escrow Agent, along with a fully executed blank stock power bearing the name of the Escrow Agent as the transferee. Upon receipt of such New Shares and other distributions, Escrow Agent shall hold in escrow such securities and the same shall be subject to all of the provisions of this Agreement relating to the Escrow Shares. Notwithstanding anything to the contrary herein, any dividend declared by the Board of Directors of Parent that is payable in cash with respect to the Escrow Shares shall not be delivered to the Escrow Agent and each Significant PEI Shareholder shall be entitled to receive such Significant PEI Shareholder's Pro Rata Share of such cash dividend. (b) Subject to the terms of the Voting Agreement, the Shareholder Representative shall have all voting rights with respect to the Escrow Shares for so long as such Escrow Shares are held in the Escrow Fund; provided that if -------- so directed by the Requisite Shareholders (as hereinafter defined) with respect to any matter submitted to a vote of the shareholders of IDS, the Shareholder Representative shall, subject to the Voting Agreement, vote the Escrow Shares as directed by the Requisite Shareholders.

Shareholder Representative as Agent. ----------------------------------- (a) Appointment. Each Significant PEI Shareholder hereby designates ----------- and appoints the Shareholder Representative as its Shareholder Representative and agent under this Agreement, and each Significant PEI Shareholder hereby irrevocably authorizes Shareholder Representative to execute and deliver the documents and to take such action or to refrain from taking such action on its behalf under the provisions of this Agreement and to exercise such powers as are set forth herein or therein, together with such other powers as are reasonably incidental thereto. In performing its functions and duties under this Agreement, Shareholder Representative shall act solely as agent of the Significant PEI Shareholders and does not assume and shall not be deemed to have assumed any obligation toward or relationship of agency or trust with or for Parent or Purchaser. (b) Nature of Duties. The duties of the Shareholder Representative ---------------- shall be mechanical and administrative in nature. The Shareholder Representative shall not have by reason of this Agreement a fiduciary relationship in respect of any Significant PEI Shareholder.

If Shareholder Representative seeks the consent or approval of any Significant PEI Shareholder to the taking or refraining from taking any action hereunder, then Shareholder Representative shall send notice thereof to each Significant PEI Shareholder. Shareholder Representative shall promptly notify each Significant PEI Shareholder any time that the Requisite Shareholders have instructed Shareholder Representative to act or refrain from acting pursuant hereto.

Shareholder Representative may at any time request instructions from the Significant PEI Shareholders with respect to any actions or approvals which by the terms of this Agreement, Shareholder Representative is permitted or required to take or to grant, and if such instructions are promptly requested, Shareholder Representative shall be absolutely entitled to refrain from taking any action or to withhold any approval and shall not be under any liability whatsoever to any person or entity for refraining from any action or withholding any approval under this Agreement until it shall have received such instructions from Requisite Shareholders or all or such other portion of the Significant PEI Shareholders as shall be prescribed by this Agreement. Without limiting the foregoing, no Significant PEI Shareholder shall have any right of action whatsoever against Shareholder Representative as a result of Shareholder Representative acting or refraining from acting under this Agreement in accordance with the instructions of Requisite Shareholders and, notwithstanding the instructions of Requisite Shareholders, the Shareholder Representative shall have no obligation to take any action if it believes, in good faith, that such action exposes Shareholder Representative to any liability for which it has not received satisfactory indemnification in accordance with Section 11(d). 6 (d) Indemnification. Significant PEI Shareholders will reimburse --------------- and indemnify Shareholder Representative for and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses (including, without limitation, reasonable attorneys' fees and expenses), advances or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against Shareholder Representative in any way relating to or arising out of this Agreement or any action taken or omitted by Shareholder Representative under this Agreement, in proportion to each Significant PEI Shareholders' Pro Rata Share, but only to the extent that any of the foregoing is not reimbursed by Parent or Purchaser; provided, -------- however, that no Significant PEI Shareholders shall be liable for any portion of ------- such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses, advances or disbursements to the extent resulting from Shareholder Representative's gross negligence or willful misconduct as determined by a court of competent jurisdiction. If any indemnity furnished to Shareholder Representative for any purpose shall, in the opinion of Shareholder Representative, be insufficient or become impaired, Shareholder Representative may call for additional indemnity and cease, or not commence, to do the acts indemnified against even if so directed by Requisite Shareholders until such additional indemnity is furnished.
