FORM OF D&O SUPPORT AGREEMENT

SUPPORT AGREEMENT (this “Agreement”), dated as of July 26, 2016 between Document Technologies, LLC, a Georgia limited liability company (“Parent”), and the undersigned stockholder, a natural person (“Stockholder”).

WHEREAS, in connection with Parent and Purchaser entering into an Agreement and Plan of Merger, dated as of the date hereof (the “Merger Agreement”), with Epiq Systems, Inc., a Missouri corporation (the “Company”), Parent has requested Stockholder, and Stockholder has agreed, to enter into this Agreement with respect to all shares of common stock, par value $0.01 per share, of the Company (the “Company Common Stock”) that Stockholder beneficially owns (such shares, together with all other shares of common stock of the Company acquired (whether beneficially or of record) by Stockholder after the date hereof and prior to the earlier of the Effective Time and the termination of Stockholder’s obligations under this Agreement, the “Shares”). Capitalized terms used but not otherwise defined herein shall have the respective meanings set forth in the Merger Agreement;

WHEREAS, at a meeting duly called and held prior to the execution of this Agreement, the Board of Directors of the Company has, upon the terms and subject to the conditions set forth in the Merger Agreement, duly adopted an amendment to the bylaws of the Company to expressly provide that Section 351.407 of the MGBCL (which is related to “control share acquisitions” as defined in Section 351.015(4) of the MGBCL) does not apply to control share acquisitions of shares of capital stock of the Company, thus rendering the provisions of Section 351.407 of the MGBCL inapplicable to the acquisition of the Shares in connection with the Merger; and

WHEREAS, Stockholder acknowledges that Parent and Purchaser are entering into the Merger Agreement in reliance on the representations, warranties, covenants and other agreements of Stockholder set forth in this Agreement.

MISCELLANEOUS

Section 5.01. Further Assurances. Parent and Stockholder shall each execute and deliver, or cause to be executed and delivered, all further documents and instruments and use its commercially reasonable efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable under applicable Law, to consummate and make effective the transactions contemplated by this Agreement.

This Agreement shall terminate upon the earliest of (a) the termination of the Merger Agreement in accordance with its terms, (b) the date of any Company Adverse Recommendation Change, and (c) without the prior written consent of the Stockholder, the making of any change, by amendment, waiver, or other modification, by any party, to any provision of the Merger Agreement that reduces or changes the form of consideration payable pursuant to the Merger Agreement.

Section 5.05. Governing Law. This Agreement shall be construed in accordance with and governed by the laws of the State of Missouri, without giving effect to any choice or conflict of laws provision or rule (whether of the State of Missouri or any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of Missouri.

Section 5.06. Specific Performance. Each party acknowledges that monetary damages would not be an adequate remedy in the event that any covenant or agreement in this Agreement is not performed in accordance with its terms, and therefore agrees that, in addition to and without limiting any other remedy or right available to the parties, each party will have the right to an injunction, temporary restraining order or other equitable relief in any court of competent jurisdiction enjoining any such breach and enforcing specifically the terms and provisions hereof. Each party agrees not to oppose the granting of such

5

relief in the event a court determines that such a breach has occurred, and to waive any requirement for the securing or posting of any bond in connection with such remedy. All rights, powers, and remedies provided under this Agreement or otherwise available in respect hereof at law or in equity shall be cumulative and not alternative, and the exercise or beginning of the exercise of any thereof by a party shall not preclude the simultaneous or later exercise of any other such right, power or remedy by a party.

This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement shall become effective when each party hereto shall have received counterparts hereof signed by all of the other parties hereto. Until and unless each party has received a counterpart hereof signed by the other party hereto, this Agreement shall have no effect and no party shall have any right or obligation hereunder (whether by virtue of any other oral or written agreement or other communication).

Section 5.08. Severability. If any term, provision or covenant of this Agreement is held by a court of competent jurisdiction or other authority to be invalid, void or unenforceable, the remainder of the terms, provisions and covenants of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated. If a final judgment of a court of competent jurisdiction declares that any term or provision of this Agreement is invalid or unenforceable, the parties hereto agree that the court making such determination shall have the power to limit such term or provision, to delete specific words or phrases or to replace such term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be valid and enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the parties hereto agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term or provision.

Section 5.09. Capacity. Stockholder is signing this Agreement solely in Stockholder’s capacity as a stockholder of the Company, and not in any other capacity and this Agreement shall not limit or otherwise affect the actions of Stockholder or any Affiliate, employee, designee or Representative of Stockholder or any of its Affiliates in any other capacity, including, if applicable, as an officer or director of the Company or any of its Subsidiaries.
