The parties know that such presently unknown or unappreciated facts could materially affect the claims or defenses of a party or parties and the desirability of entering into this Agreement. It is nonetheless the intent of the parties to give a full and complete release and discharge of the Released Claims. To that end, with respect to the Released Claims only, the parties expressly waive and relinquish any and all provisions, rights and benefits conferred by any law of the United States or of any state or territory of the United States or of any other relevant jurisdiction, or principle of common law, which is similar, comparable or equivalent to Section 1542 of the California Civil Code. With respect to the Released Claims only, the Parties expressly waive and relinquish, to the fullest extent permitted by law, the provisions, rights, and benefits of Section 1542 of the California Civil Code, or any New York, Delaware, Illinois, Oklahoma, Texas or other state’s counterpart thereto, which provides:

A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS SETTLEMENT WITH THE DEBTOR.

Section 6.2 Covenant Not to Xxx.

However, any Released Person may plead this Agreement as a complete defense and bar to any Released Claim brought or threatened in derogation of this covenant not to xxx.

Section 6.3 Accord and Satisfaction. This Agreement and the releases reflected herein shall be effective as a full and final accord and satisfaction and release of all of the Released Claims.

Section 6.4 Indemnification of the Series B Investors and Post Oak.

(a) Chaparral agrees to hold harmless and indemnify the Series B Investors, Post Oak and each of their respective parents, subsidiaries and affiliates and their respective officers, directors, managing directors, stockholders, partners, members, predecessor entities, successors and assigns, parents, subsidiaries, affiliates, employees and attorneys and other advisors and agents (including debt and equity financing sources) (collectively, the “Chaparral Series B Indemnified Persons”), from and against any and all losses, claims, demands, judgments, damages, liabilities and expenses, including (without limitation) any payments made in settlement of any such claims (each, a “Loss” and, collectively, the “Losses”) whatsoever (including reasonable expenses incurred in preparing or defending against any litigation or proceeding, commenced or threatened, or any claims whatsoever whether or not resulting in any liability) imposed on or incurred by any Chaparral Series B Indemnified Person, to the extent that such Loss results from any claim or cause of action that is a Chaparral Released Claim brought by or on behalf of any one or more of the Chaparral Releasing Parties. Any person indemnified initially hereunder shall remain so indemnified, regardless of any subsequent change in their position or status that qualified such person for indemnification initially.

(b) Edge agrees to hold harmless and indemnify the Series B Investors, Post Oak and each of their respective parents, subsidiaries and affiliates and their respective officers, directors, managing directors, stockholders, partners, members, predecessor entities, successors and assigns, parents, subsidiaries, affiliates, employees and attorneys and other advisors and agents (including debt and equity financing sources) (collectively, the “Edge Series B Indemnified Persons”), from and against any and all Losses whatsoever (including reasonable expenses incurred in preparing or defending against any litigation or proceeding, commenced or threatened, or any claims whatsoever

whether or not resulting in any liability) imposed on or incurred by any Edge Series B Indemnified Person, to the extent that such Loss results from any claim or cause of action that is an Edge Released Claim brought by Edge. Any person indemnified initially hereunder shall remain so indemnified, regardless of any subsequent change in their position or status that qualified such person for indemnification initially.

(c) The beneficiaries of the indemnification provisions set forth in Sections 6.4(a) and 6.4(b) are, collectively, the “Indemnified Persons.” If an Indemnified Person intends to seek indemnification pursuant to this Section 6.4 with respect to any claim, demand or cause of action described in Sections 6.4(a) or 6.4(b) , such Indemnified Person shall promptly provide written notice to the party from whom indemnification is being sought (in accordance with Section 7.5 hereof) describing such claim, demand or cause of action in reasonable detail and providing copies of all material written evidence thereof and the estimated amount of the Losses that have been or may be sustained by the Indemnified Person; provided, however, that the failure to provide such notice or information shall not affect the obligations of the indemnifying party unless it is actually prejudiced thereby, and then it will be relieved of such obligation only to the extent of the prejudice. Any Indemnified Person shall be entitled to retain its own counsel in connection with any such asserted claim, demand or cause of action or defense thereof. No Indemnified Person shall agree to a settlement of, or the entry of any judgment arising from, any claim or cause of action, without the prior written consent of the indemnifying party, such consent not to be unreasonably conditioned, withheld or delayed; provided, however, that in no event shall an Indemnified Person be required to admit or consent to any finding of any liability, wrongdoing, damages or injunctive relief whatsoever.

This Agreement shall be binding upon and shall inure to the benefit of the parties hereto (including the Released Persons) and their respective successors and, subject to the preceding sentence, assigns.

Section 7.7 Severability. Any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or

unenforceable the remaining terms and provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, such provision shall be interpreted to be only as broad as is enforceable.

Section 7.8 Entire Agreement; No Third-Party Beneficiaries. This Agreement constitutes the entire agreement of the parties hereto with respect to the subject matter hereof, and supersedes all other prior agreements and understandings, both written and oral, between the parties, or any of them, with respect to the subject matter hereof and thereof. Each party hereto acknowledges and agrees that each of the non-party Released Persons are express third party beneficiaries of: (i) the releases of such non-party Released Persons contained in Sections 4.1, 4.2, 4.3, 5.1, 5.2, 5.3 and 5.4, (ii) the covenants not to xxx contained in Section 6.2 and (iii) the indemnification provisions contained in Section 6.4 of this Agreement, and such non-party Released Persons are entitled to enforce rights under such sections to the same extent that such non-party Released Persons could enforce such rights if they were a party to this Agreement. Except as provided in the preceding sentence, there are no third party beneficiaries to this Agreement, and this Agreement is not otherwise intended to and shall not otherwise confer upon any person other than the parties hereto any rights or remedies hereunder.

Section 7.9 Headings. Headings of the Articles and Sections of this Agreement are for convenience of the parties only and shall be given no substantive or interpretive effect whatsoever.

Section 7.10 Interpretation. When a reference is made in this Agreement to an Article or Section, such reference shall be to an Article or Section of this Agreement unless otherwise indicated. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The words “hereof,” “herein,” “hereafter” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The word “or” shall be deemed to mean “and/or.” The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms and to the masculine as well as to the feminine and neuter genders of such term. Any agreement, instrument or statute defined or referred to herein or in any agreement or instrument that is referred to herein means such agreement, instrument or statute as from time to time amended, modified or supplemented, including (in the case of agreements or instruments) by waiver or consent and (in the case of statutes) by succession of comparable successor statutes and references to all attachments thereto and instruments incorporated therein. Each of the parties has participated in the drafting and negotiation of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement must be construed as if it is drafted by all the parties, and no provision of this Agreement shall be construed against any party based on its authorship of any of the provisions of this Agreement.
