ARTICLE VI

SCOPE OF
RELEASES, COVENANT NOT TO SUE AND INDEMNIFICATION

 

Section 6.1 Scope of Releases and Discharge.  The beneficiaries of the releases set forth
in Sections 4.1, 4.2, 4.3, 5.1, 5.2, 5.3 and 5.4 (collectively, as it relates
to the party granting a release, the “Released Claims”) are, collectively, the “Released
Persons.” The parties acknowledge and agree that they may be unaware of or may
discover facts in addition to or different from those which they now know or
believe to be true related to or concerning the Released Claims or the Released
Persons. 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.

 

8

 

Section 6.2 Covenant Not to Sue.  Each of the parties hereto covenants, on
behalf of itself and (i) the Investor Releasing Parties and the
Investor-Edge Releasing Parties, in the case of the Series B Investors, (ii) the
Chaparral Releasing Parties and Chaparral-Edge Releasing Parties, in the case
of Chaparral, (iii) the Post Oak Releasing Parties and the Post Oak-Edge
Releasing Parties, in the case of Post Oak, and, (iv) to the fullest
extent allowed by law, the Edge Releasing Parties, in the case of Edge, and
with respect to the Chaparral Releasing Parties, the Chaparral-Edge Releasing
Parties and the Edge Releasing Parties, effective upon the payment and receipt
of the Termination Payment as provided in Section 2.1(c), not to bring any
Released Claim before any court, arbitrator, or other tribunal in any
jurisdiction, whether as a claim, cross-claim, or counterclaim.  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 sue.

 

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 

 

9

 

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.

 

ARTICLE VII

Section 7.2 Non-Disparagement.  Other than as (and to the extent) a party may
determine is necessary or appropriate to respond to any legal or regulatory
process or proceeding or to give appropriate testimony or to file any necessary
documents in any legal or regulatory proceeding or is otherwise required by
law, legal process or regulation, no party to this Agreement shall make any
public statements or any private statements that disparage, denigrate or malign
any of the other parties or persons released herein, concerning the subject
matter of this Agreement, the Letter of Intent, Stock Purchase Agreement,
Assumption Agreements, Merger Agreement, Commitment Letter or the business or
practices of the other parties hereto. Notwithstanding anything set forth in
Sections 5.1 and 5.2 to the contrary, nothing herein shall prevent or limit any
parties’ right or ability to (a) accurately and fully describe the
transactions, agreements and other matters set forth herein or underlying this
Agreement to existing or potential investors, creditors or other third parties
or (b) make any other disclosure required by law, legal process or
regulation.  This Agreement constitutes
the termination of the Letter of Intent, Stock Purchase Agreement and

of any wrongdoing, liability or damages by any of the parties hereto.

 

Section 7.3 Counterparts; Effectiveness.  This Agreement may be executed in two or more
counterparts (including by facsimile), each of which shall be an original, with

courts of the State of Delaware and waive any objection or defense thereto with
respect to any dispute regarding this Agreement, including any action for
indemnification hereunder. ALL PARTIES WAIVE ANY RIGHT TO TRIAL BY JURY.

4.3, 5.1, 5.2, 5.3 and 5.4, (ii) the covenants not to sue contained in Section 6.2
and (iii) the indemnification provisions contained in Section 6.4 of

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.
