Releases of Collateral (i) If any Collateral shall be sold, transferred or otherwise disposed of by any Obligor in a transaction permitted by the Credit Agreement, then the Administrative Agent, at the request and sole expense of such Obligor, shall promptly execute and deliver to such Obligor all releases and other documents, and take such other action, reasonably necessary for the release of the Liens created hereby or by any other Collateral Document on such Collateral. (ii) The Administrative Agent may release any of the Pledged Equity from this Agreement or may substitute any of the Pledged Equity for other Pledged Equity without altering, varying or diminishing in any way the force, effect, lien, pledge or security interest of this Agreement as to any Pledged Equity not expressly released or substituted, and this Agreement shall continue as a first priority lien on all Pledged Equity not expressly released or substituted.
Subsidiary Guarantors; Pledges; Additional Collateral; Further Assurances (a) As promptly as possible but in any event within thirty (30) days (or such later date as may be agreed upon by the Administrative Agent) after any Person qualifies as, or is designated by the Borrower or the Administrative Agent as, a Subsidiary Guarantor pursuant to the definition of “Material Subsidiary”, the Borrower shall provide the Administrative Agent with written notice thereof setting forth information in reasonable detail describing the material assets of such Person and shall cause each such Person which qualifies as a Material Subsidiary to deliver to the Administrative Agent a joinder to the Subsidiary Guaranty and the Security Agreement (in each case in the form contemplated thereby) pursuant to which such Person agrees to be bound by the terms and provisions thereof, such Subsidiary Guaranty and the Security Agreement to be accompanied by appropriate corporate resolutions, other corporate documentation and legal opinions in form and substance reasonably satisfactory to the Administrative Agent and its counsel.
Additional Collateral; Additional Guarantors (a) In connection with each redetermination of the Borrowing Base, the Borrower shall review the Reserve Report and the list of current Mortgaged Properties (as described in Section 8.12(c)(vi)) to ascertain whether the Mortgaged Properties represent at least 80% of the total value of the Oil and Gas Properties evaluated in the most recently completed Reserve Report after giving effect to exploration and production activities, acquisitions, dispositions and production. In the event that the Mortgaged Properties do not represent at least 80% of such total value, then the Borrower shall, and shall cause its Subsidiaries to, grant to the Administrative Agent or its designee as security for the Indebtedness a first-priority Lien interest (provided the Excepted Liens of the type described in clauses (a) to (d) and (f) of the definition thereof may exist, but subject to the provisos at the end of such definition) on additional Oil and Gas Properties not already subject to a Lien of the Security Instruments such that after giving effect thereto, the Mortgaged Properties will represent at least 80% of such total value. All such Liens will be created and perfected by and in accordance with the provisions of deeds of trust, security agreements and financing statements or other Security Instruments, all in form and substance reasonably satisfactory to the Administrative Agent or its designee and in sufficient executed (and acknowledged where necessary or appropriate) counterparts for recording purposes. In order to comply with the foregoing, if any Subsidiary places a Lien on its Oil and Gas Properties and such Subsidiary is not a Guarantor, then it shall become a Guarantor and comply with Section 8.14(b).
