Exhibit A

Description of Corporate Restructuring
 
All capitalized terms not otherwise defined herein shall have the meaning assigned to such terms in the Amendment to which this Exhibit A is an exhibit.

1.
Gran Tierra will form a new Cayman corporation, referred to as “ CFC 1 .”  CFC 1 will be a wholly-owned direct subsidiary of Gran Tierra.
 
2.

4.
Gran Tierra will form a new Delaware limited liability company, referred to as “ LLC 1 .”  LLC 1 will initially be a wholly-owned direct subsidiary of Gran Tierra.
 
5.
Prior to the time that the Restructuring becomes effective (the “ Restructuring Effective Time ”), Argosy Energy Corp., a Delaware corporation and general partner in the Partnership (“ AEI ”), will convert (the “ AEI Conversion ”) from a Delaware corporation into a newly formed Delaware limited liability company (“ AEI LLC ”) by simultaneously filing articles of organization and a certificate of conversion with the Secretary of State of Delaware.
 
 
a)
Existing stock ownership in AEI will convert to membership interests in AEI LLC on a pro rata basis.
 
 
b)
Gran Tierra will own 100% of the outstanding stock of AEI immediately prior to the AEI Conversion and will own 100% of the membership interest in AEI LLC immediately following the AEI Conversion.
 
 
c)
There will be executed a Limited Liability Company Agreement providing for the governance of AEI LLC.  The sole Member of AEI LLC will be Gran Tierra.
 
6.
At the Restructuring Effective Time, Gran Tierra will transfer 100% of its ownership interest in the Partnership and 100% of its ownership interest in AEI LLC to LLC 1.  As a result, as of the Restructuring Effective Time:
 
a)           LLC 1 will hold 100% of the membership interest in AEI LLC.
 
 
b)
AEI LLC will continue to be the general partner of the Partnership, holding a .7413% interest therein.
 
 
c)
LLC 1 will become the limited partner of the Partnership, holding a 99.2857% interest therein.
 
 
d)
LLC 1 will directly or indirectly control 100% of the equity interests in the Partnership.
 
7.
LLC 1 will create separate LLC 1 series (individually or collectively, the “ LLC Series ”).
 
 

 
 
 
a)
Each Series will have separate rights, powers and duties and will be generally treated as a separate entity under Delaware law.
 
 
b)
Each Series will represent rights to one of the nine Colombian Properties, as defined below. Thus, for example, Series 1 may represent rights to the interests in the Santana Block and Series 2 may represent rights to the interests in the Guauyaco block. As such:
 
 
i.
Series 1 will have rights, exclusive to other Series, in the assets in the Santana Block and the income derived therefrom.
 
 
ii.
No other Series will have a claim of right to the assets of or income derived from the Santana block.
 
 
iii.
Liability of Series 1 will be limited to the assets of the Santana block.
 
c)           There will be a total of nine separate LLC Series created under LLC 1, as follows:
 
 
i.
Three LLC Series will be created, each representing one of the three Colombian production properties (the “ Colombian Production Properties ”), as follows:
 
·            Santana block – 35% economic interest;
 
·            Guayuyaco block – 35% economic interest; and
 
·            Chaza block – 50% economic interest.
 
 
ii.
Six additional LLC Series will be created, each representing one of the six Colombian Exploration Properties (the “ Colombian Exploration Properties ” and together with the Colombian Production Properties, the “ Colombian Properties ”) as follows:
 
 
·
Rio Magdalena – 100% economic interest (currently farming out 60% of economic interest);
 
 
·
Talora – 20% economic interest (currently farming out whole interest);
 
 
·
Mecaya – 15% economic interest (currently farming out whole interest);
 
 
·
Azar – 40% economic interest (currently farming out 50-80% of economic interest);
 
 
·
Putumayo West A – Currently under evaluation but if converted to E&E contract, portion to be farmed out; and
 
 
·
Putumayo West B – Negotiating E&E contract; portion will be farmed out.
 
 
d)
All assets and other rights held in any of the Colombian Properties are the result of contracts to which the Partnership is a party.
 
 

 
 
 
i.
The Partnership will continue to be the party to such agreements following the Restructuring Effective Time.
 
 
ii.
No assignment or other transfer of any such agreement or rights provided thereunder will occur as a result of the Restructuring.
 
 
e)
Collectively, the nine LLC Series will represent ownership of 100% of the interests in the Colombian Properties and thus 100% of the assets of the Partnership.
 
8.
The partnership agreement of the Partnership will be amended and restated in connection with the Restructuring primarily to cause the Partnership to account separately for each of the nine Colombian Properties related to each of the nine LLC Series.
 
9.
Each of the LLC Series will enter into an indemnity agreement (the “ Indemnity Agreement ”).
 
 
a)
The parties to the Indemnity Agreement will be each of the nine LLC Series, AEI LLC, and the Partnership.
 
 
b)
Under the Indemnity Agreement, each respective LLC Series will indemnify all other LLC Series against judgments or liabilities not related to the assets held by such other LLC Series.
 
 
c)
Under the Indemnity Agreement, each of the nine LLC Series will indemnify the Partnership and AEI LLC against losses arising from assets of such LLC Series.
 
10.
Additionally, the Indemnity Agreement will include a guaranty.
 
 
a)
The guarantors will be Gran Tierra and CFC 1 as the members of the Series and each guarantor will guarantee any obligations of any of the LLC Series owned by such guarantor arising from the Indemnity Agreement.
 
11.
At the Restructuring Effective Time, Gran Tierra will transfer its interests in the three LLC Series related to the three Colombian Production Properties to CFC 1.
 
 
a)
The transfer will be made as an additional capital contribution by Gran Tierra to CFC 1, its wholly-owned foreign subsidiary.
 
 
b)
No consideration will be received by Gran Tierra in return for such contribution.
 
 
c)
The end result of such transfers will be that profits derived from the Colombian Production Properties will be earned by and attributed to a Cayman entity, CFC 1.
 
 
d)
Interests in the other six series of LLC 1, attributable to the Colombian Exploration Properties, will be treated as continuing to be held by Gran Tierra.
 
12.
At the Restructuring Effective Time, Gran Tierra Energy Inc., an Alberta corporation (“ GT CAN ”) will transfer all management agreements to which GT CAN is a party (but not lease agreements for property and equipment) and all of its employees to ULC.
 

 
13.
Gran Tierra will amend its credit facility agreement and related agreements (the “ Credit Facility ”) with Standard Bank to terminate certain existing pledges created thereunder and to create new pledges granted by newly formed entities to properly reflect the post-Restructuring structure.
 
14.
In a separate and subsequent action Gran Tierra may assign the Credit Facility to CFC 1.

-5-

 
(b)            By accepting this Agreement, the Pledgee and the Secured Parties do not intend to become a partner of the Issuer or otherwise be deemed to be a partner or co-venturer with respect to any Pledgor or the Issuer either before or after an Event of Default shall have occurred.  The Pledgee and the Secured Parties shall have only those powers set forth herein and shall assume none of the duties, obligations or liabilities of any Pledgor or of a partner of the Issuer.  Neither the Pledgee nor any Secured Party shall be obligated to perform or discharge any obligation of any Pledgor as a result of the pledge hereby effected.
 
(c)            The acceptance by the Pledgee and the Secured Parties of this Agreement, with all of the rights, powers, privileges and authority so created, shall not at any time or in any event obligate the Pledgee or any Secured Party to appear in or defend any action or proceeding relating to the Pledged Property to which it is not a party, or to take any action hereunder or thereunder, or to expend any money or incur any expense or perform or discharge any obligation, duty or liability hereunder or otherwise with respect to the Pledged Property.
 
7.             RIGHTS AND REMEDIES
 
At any time after an Event of Default exists or has occurred and is continuing, in addition to all other rights and remedies of the Pledgee and the Secured Parties, whether provided under this Agreement, the Credit Agreement, the other Loan Documents, applicable law or otherwise, the Pledgee shall have the following rights and remedies which may be exercised without notice to, or consent by, any Pledgor except as such notice or consent is expressly provided for hereunder or such notices which such Pledgor may not waive in accordance with applicable law:
 
(a)            The Pledgee, at its option, shall be empowered to exercise its continuing right to instruct the Issuer in writing (or the appropriate transfer agent of the Pledged Interests) to register any or all of the Pledged Interests in the name of the Pledgee or in the name of the Pledgee’s nominee (including, without limitation, any Secured Party) and the Pledgee may complete, in any manner the Pledgee may deem expedient, any assignments or other documents heretofore or hereafter executed in blank by the Secured Parties and delivered to the Pledgee.  After said written instruction, and without further notice, the Pledgee shall have the exclusive right to exercise all voting and partnership rights with respect to the Pledged Property, and exercise any and all rights of conversion, redemption, exchange, subscription or any other rights, privileges, or options pertaining to the Pledged Property as if the Pledgee were the absolute owner thereof, including, without limitation, the right to exchange, in its discretion, any and all of the Pledged Property upon any merger, consolidation, reorganization, recapitalization or other readjustment with respect thereto.  Upon the exercise of any such rights, privileges or options by the Pledgee, the Pledgee shall have the right to deposit and deliver any and all of the Pledged Property to any committee, depository, transfer agent, registrar or other designated agency upon such terms and conditions as the Pledgee may determine, all without liability, except to account for property actually received by the Pledgee.  However, the Pledgee shall have no duty to exercise any of the aforesaid rights, privileges or options (all of which are exercisable in the sole discretion of the Pledgee) and shall not be responsible for any failure to do so or delay in doing so.
 
-6-

 
(b)            The Pledgee may, in its good faith discretion (i) collect, foreclose, receive, appropriate, setoff and realize upon any and all Pledged Property, (ii) sell, lease, transfer, assign, deliver or otherwise dispose of any and all Pledged Property (including entering into contracts with respect thereto, public or private sales at any exchange, broker’s board, at any office of the Pledgee or elsewhere) at such prices or terms as the Pledgee may deem reasonable, for cash, upon credit or for future delivery, with the Pledgee having the right to purchase the whole or any part of the Pledged Property at any such public sale, all of the foregoing being free from any right or equity of redemption of any Pledgor, which right or equity of redemption is hereby expressly waived and released by each Pledgor (to the extent permitted by applicable law).  If notice of disposition of Pledged Property is required by law, ten (10) days prior notice by the Pledgee to any Pledgor designating the time and place of any public sale or the time after which any private sale or other intended disposition of Pledged Property is to be made, shall be deemed to be reasonable notice thereof and any other notice.  The Pledgee shall apply the cash proceeds of Pledged Property actually received by the Pledgee from any sale, lease, foreclosure or other disposition of the Pledged Property to payment of the Obligations then due, in whole or in part and in accordance with the terms of Section 10 of the Credit Agreement, and thereafter may hold such proceeds as cash collateral for the Obligations not then due.  Each Pledgor shall remain liable to the Pledgee and the Secured Parties for the payment of any deficiency with interest at the highest rate provided for in the Credit Agreement and agrees to indemnify the Pledgee and the Secured Parties from all costs and expenses of collection or enforcement incurred in good faith by each of them or on their behalf, including reasonable attorneys’ fees and expenses, as provided in the Credit Agreement.
 
(c)            Each Pledgor recognizes that the Pledgee may be unable to effect a public sale of all or part of the Pledged Property by reason of certain prohibitions contained in the Securities Act of 1933, as amended, as now or hereafter in effect or in applicable Blue Sky or other state securities law, as now or hereafter in effect, but may be compelled to resort to one or more private sales to a restricted group of purchasers who will be obliged to agree, among other things, to acquire such Pledged Property for their own account for investment and not with a view to the distribution or resale thereof.  If at the time of any sale of the Pledged Property or any part thereof, the same shall not, for any reason whatsoever, be effectively registered under the Securities Act of 1933 (or other applicable state securities law), as then in effect, the Pledgee in its sole and absolute discretion is authorized to sell such Pledged Property or such part thereof by private sale in such manner and under such circumstances as the Pledgee or its counsel may deem necessary or advisable in order that such sale may legally be effected without registration.  Each Pledgor agrees that private sales so made may be at prices and other terms less favorable to the seller than if such Pledged Property were sold at public sale, and that the Pledgee has no obligation to delay the sale of any such Pledged Property for the period of time necessary to permit the Issuer, even if the Issuer would agree, to register such Pledged Property for public sale under such applicable securities laws.  Each Pledgor agrees that any private sales made under the foregoing circumstances shall be deemed to have been made in a commercially reasonable manner.
 
-7-

 
(d)            All of the rights and remedies of the Pledgee and the Secured Parties, including, but not limited to, the foregoing and those otherwise arising under this Agreement, the Credit Agreement and the other Loan Documents, the instruments comprising the Pledged Property, applicable law or otherwise, shall be cumulative and not exclusive and shall be enforceable alternatively, successively or concurrently as the Pledgee may deem expedient.  No failure or delay on the part of the Pledgee or any Secured Party in exercising any of its options, powers or rights or partial or single exercise thereof, shall constitute a waiver of such option, power or right.
 
8.             JURY TRIAL WAIVER; OTHER WAIVERS AND CONSENTS; GOVERNING LAW
 
(a)            The validity, interpretation and enforcement of this Agreement and any dispute arising out of the relationship between any Pledgor and the Pledgee or any Secured Party, whether in contract, tort, equity or otherwise, shall be governed by the laws of the State of New York, including, without limitation, Section 5-1401 of the New York General Obligations Law.
 
(b)            Each Pledgor hereby irrevocably consents and submits to the non-exclusive jurisdiction of the Supreme Court of the State of New York, sitting in the Borough of Manhattan, The City of New York and the United States District Court for the Southern District of New York, whichever the Pledgee may elect, and waives any objection based on venue or forum non conveniens with respect to any action instituted therein arising under this Agreement or any of the other Loan Documents or in any way connected with or related or incidental to the dealings of any Pledgor and the Pledgee or any Secured Party in respect of this Agreement or any of the other Loan Documents or the transactions related hereto or thereto, in each case whether now existing or hereafter arising, and whether in contract, tort, equity or otherwise, and agrees that any dispute with respect to any such matters shall be heard only in the courts described above (except that the Pledgee and the Secured Parties shall have the right to bring any action or proceeding against any Pledgor or its property in the courts of any other jurisdiction that the Pledgee deems necessary or appropriate in order to realize on any collateral at any time granted by the Borrower or any Pledgor to the Pledgee or any Secured Party or to otherwise enforce its rights against any Pledgor or its property).
 
(c)            Each Pledgor hereby irrevocably designates, appoints and empowers CT Corporation as its designee, appointee and agent to receive, accept and acknowledge for and on its behalf, and in respect of its property, service of any and all legal process which may be served in any action or proceeding.  If for any reason CT Corporation shall cease to be available to act as such, each Pledgor agrees to designate a new designee, appointee and agent on the terms and for the purposes of this provision satisfactory to the Pledgee.  Each Pledgor hereby irrevocably consents to the service of process out of any of the courts mentioned in Section 8(b) above in any such action or proceeding by the mailing of copies thereof by registered or certified mail, postage prepaid to such Pledgor at its respective address set forth on the signature pages hereof.
 
-8-

 
(d)            EACH PLEDGOR HEREBY WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (i) ARISING UNDER THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS OR (ii) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO OR THERETO IN RESPECT OF THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS OR THE TRANSACTIONS RELATED HERETO OR THERETO IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT, EQUITY OR OTHERWISE.  EACH PLEDGOR HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT ANY PLEDGOR, ANY SECURED PARTY OR THE PLEDGEE MAY FILE AN ORIGINAL COUNTERPART OF A COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF PLEDGORS TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.
 
(e)            Neither the Pledgee nor any Secured Party shall have any liability to any Pledgor (whether in tort, contract, equity or otherwise) for losses suffered by such Pledgor in connection with, arising out of, or in any way related to the transactions or relationships contemplated by this Agreement, or any act, omission or event occurring in connection herewith, unless with respect to the Pledgee or any Secured Party, as applicable, it is determined by a final and non-appealable judgment or court order binding on the Pledgee or such Secured Party, as applicable, that the losses were the result of acts or omissions constituting gross negligence or willful misconduct or bad faith of the Pledgee or the relevant Secured Party, as applicable.  In any such litigation, the Pledgee and the Secured Parties shall be entitled to the benefit of the rebuttable presumption that they acted in good faith and with the exercise of ordinary care in the performance by them of the terms of the Credit Agreement and the other Loan Documents.  Each Pledgor: (i) certifies that neither the Pledgee nor any Secured Party nor any representative, agent or attorney acting for or on behalf of the Pledgee or any Secured Party has represented, expressly or otherwise, that the Pledgee and the Secured Parties would not, in the event of litigation, seek to enforce any of the waivers or other agreements for their benefit provided for in this Agreement or any of the other Loan Documents and (ii) acknowledges that in entering into this Agreement and the other Loan Documents, the Pledgee and the Secured Parties are relying upon, among other things, the waivers and certifications set forth in this Section 8(e) and elsewhere herein and therein.
 
9.             RELEASE OF COLLATERAL
 
(a)            Upon termination of the Commitments and payment and satisfaction in full (in cash or other immediately available funds) of all Loans and all other Obligations and, in respect of contingent Letter of Credit Liabilities, after cash collateral has been deposited with respect thereto or after such Letter of Credit Liabilities have been fully guaranteed by Export Development Canada (EDC) on terms in form and substance acceptable to the Majority Banks in accordance with the terms and conditions of the Credit Agreement, the Pledged Property shall be released from the Lien created hereby and this Agreement and all obligations of the Pledgee and the Pledgors hereunder shall terminate, all without delivery of any instrument or performance of any act by any Person, and all rights to the Pledged Property shall revert to the Pledgors.  At the request of the Pledgors following any such termination, the Pledgee shall deliver to Pledgors any Pledged Property held by the Pledgee hereunder and execute and deliver to Pledgors such documents as Pledgors shall reasonably request to evidence such termination.
 
-9-

 
(b)            If the Pledgee, pursuant to the terms of the Credit Agreement or any other Loan Documents, shall release any Lien upon any Pledged Property, such Pledged Property shall be released from the Lien created hereby to the extent provided under, and subject to the terms and conditions set forth in the Credit Agreement or such other Loan Document.  In connection therewith, the Pledgee, at the request and of Pledgors, shall execute and deliver to Pledgors all releases or other documents, including, without limitation, UCC amendment or termination statements, reasonably necessary or desirable for the release of the Lien created hereby on such Pledged Property.
 
10.             MISCELLANEOUS
 
(a)            Each Pledgor authorizes the Pledgee to file or record UCC financing statements with respect to the Pledged Property of such Pledgor with or without the signature of such Pledgor, in such form and in such offices as the Pledgee reasonably determines appropriate to perfect the security interests of the Pledgee under this Agreement; provided that nothing herein shall relieve such Pledgor from its obligation to file or record any UCC financing or continuation statement with respect to its Pledged Property.
 
(b)            Each Pledgor agrees that at any time and from time to time upon the written request of the Pledgee, such Pledgor shall execute and deliver such further documents, in form satisfactory to the Pledgee’s counsel, and will take or cause to be taken such further acts as the Pledgee may request in order to effect the purposes of this Agreement and perfect or continue the perfection of the security interest in the Pledged Property granted to the Pledgee hereunder.
 
(c)            Beyond the exercise of reasonable care to assure the safe custody of the Pledged Property (whether such custody is exercised by the Pledgee, or the Pledgee’s nominee, agent or bailee) the Pledgee or the Pledgee’s nominee agent or bailee shall have no duty or liability to protect or preserve any rights pertaining thereto and shall be relieved of all responsibility for the Pledged Property upon surrendering it to Pledgors or foreclosure with respect thereto.
 
(d)            All notices, requests and other communications provided for herein (including, without limitation, any modifications of, or waivers or consents under, this Agreement) shall be given or made by fax or other writing and faxed, mailed or delivered to the intended recipient at the “Address for Notices” specified below its name on the signature pages hereof.
 
(e)            All references to the plural herein shall also mean the singular and to the singular shall also mean the plural.  All references to any Pledgor, the Pledgee, any Secured Party and the Issuer pursuant to the definitions set forth in the recitals hereto, or to any other person herein, shall include their respective successors and assigns.  The words “hereof,” “herein,” “hereunder,” “this Agreement” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not any particular provision of this Agreement and as this Agreement now exists or may hereafter be amended, modified, supplemented, extended, renewed, restated or replaced.
 
-10-

 
(f)            This Agreement shall be binding upon each Pledgor and its respective successors and assigns and shall inure to the benefit of and be enforceable by the Pledgee and the Secured Parties and their respective successors, endorsees, transferees and assigns, except that no Pledgor may assign its rights under this Agreement without the prior written consent of the Pledgee and the Secured Parties.  Any such purported assignment without such express prior written consent shall be void.  The liquidation, dissolution or termination of any Pledgor shall not terminate this Pledge as to such entity or as to any of the other Pledgors. The terms and provisions of this Agreement are for the purpose of defining the relative rights and obligations of the Borrower, the Pledgors, the Pledgee and the Secured Parties with respect to the transactions contemplated hereby and there shall be no third party beneficiaries of any of the terms and provisions of this Agreement.
 
(g)            If any provision of this Agreement is held to be invalid or unenforceable, such invalidity or unenforceability shall not invalidate this Agreement as a whole, but this Agreement shall be construed as though it did not contain the particular provision held to be invalid or unenforceable and the rights and obligations of the parties shall be construed and enforced only to such extent as shall be permitted by applicable law.
 
(h)            This Agreement, any supplements hereto, and any instruments or documents delivered or to be delivered in connection herewith, represents the entire agreement and understanding of the parties hereto concerning the subject matter hereof, and supersedes all other prior agreements, understandings, negotiations and discussions, commitments, proposals, offers and contracts concerning the subject matter hereof, whether oral or written.  In the event of any inconsistency between the terms of this Agreement and any exhibit hereto, the terms of this Agreement shall govern.
 
(i)            Neither this Agreement nor any provision hereof shall be amended, modified, waived or discharged orally or by course of conduct, but only by a written agreement signed by an authorized officer of the Pledgee.  The Pledgee shall not by any act, delay, omission or otherwise be deemed to have expressly or impliedly waived any of its rights, powers and/or remedies unless such waiver shall be in writing and signed by an authorized officer of the Pledgee.  Any such waiver shall be enforceable only to the extent specifically set forth therein.  A waiver by the Pledgee of any right, power and/or remedy on any one occasion shall not be construed as a bar to or waiver of any such right, power and/or remedy that the Pledgee would otherwise have on any future occasion, whether similar in kind or otherwise.
 
(j)            This Agreement may be executed in any number of counterparts, each of which shall be an original, but all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of this Agreement by telefacsimile or electronic delivery shall have the same force and effect as the delivery of an original executed counterpart of this Agreement.  Any party delivering an executed counterpart of this Agreement by telefacsimile or electronic transmission shall also deliver an original executed counterpart, but the failure to do so shall not affect the validity, enforceability or binding effect of this Agreement.
 
-11-

 
(k)            Each Pledgor agrees that, if pursuant to Section 9.16 of the Credit Agreement, it shall be required to cause a Subsidiary that is not a pledgor to become a pledgor hereunder, or if for any reason the Borrower desires any such Subsidiary to become a pledgor hereunder, such Subsidiary shall execute and deliver to the Pledgee a Pledge Agreement Supplement in substantially the form of Exhibit B (a “ Pledge Supplement ”) attached hereto and shall thereafter for all purposes be a party hereto and have the same rights, benefits and obligations as a pledgor party hereto as if originally named as a pledgor herein.  The rights and obligations of each Pledgor hereunder shall remain in full force and effect notwithstanding the addition of any new Pledgor as a party to this Agreement.

7.               RIGHTS AND REMEDIES
 
At any time after an Event of Default exists or has occurred and is continuing, in addition to all other rights and remedies of the Pledgee and the Secured Parties, whether provided under this Agreement, the Credit Agreement, the other Loan Documents, applicable law or otherwise, the Pledgee shall have the following rights and remedies which may be exercised without notice to, or consent by, the Pledgor except as such notice or consent is expressly provided for hereunder or such notices which the Pledgor may not waive in accordance with applicable law:
 
-5-

 
(a)            The Pledgee, at its option, shall be empowered to exercise its continuing right to instruct the Issuer in writing (or the appropriate transfer agent of the Pledged Interests) to register any or all of the Pledged Interests in the name of the Pledgee or in the name of the Pledgee’s nominee (including, without limitation, any Secured Party) and the Pledgee may complete, in any manner the Pledgee may deem expedient, any assignments or other documents heretofore or hereafter executed in blank by the Secured Parties and delivered to the Pledgee.  After said written instruction, and without further notice, the Pledgee shall be admitted as a member of the Issuer without any further approval of the Pledgor or the Issuer and without any requirement for the Pledgee to comply with any of the conditions or other requirements of the LLC Agreement and without conferring upon any member of the Issuer any option (whether under the LLC Agreement or otherwise) to acquire the membership interests so transferred to the Pledgee and shall have the exclusive right to exercise all voting and limited liability company rights with respect to the Pledged Property, and exercise any and all rights of conversion, redemption, exchange, subscription or any other rights, privileges, or options pertaining to the Pledged Property as if the Pledgee were the absolute owner thereof, including, without limitation, the right to exchange, in its discretion, any and all of the Pledged Property upon any merger, consolidation, reorganization, recapitalization or other readjustment with respect thereto.  Upon the exercise of any such rights, privileges or options by the Pledgee, the Pledgee shall have the right to deposit and deliver any and all of the Pledged Property to any committee, depository, transfer agent, registrar or other designated agency upon such terms and conditions as the Pledgee may determine, all without liability, except to account for property actually received by the Pledgee.  However, the Pledgee shall have no duty to exercise any of the aforesaid rights, privileges or options (all of which are exercisable in the sole discretion of the Pledgee) and shall not be responsible for any failure to do so or delay in doing so.
 
(b)            The Pledgee may, in its good faith discretion (i) collect, foreclose, receive, appropriate, setoff and realize upon any and all Pledged Property, (ii) sell, lease, transfer, assign, deliver or otherwise dispose of any and all Pledged Property (including entering into contracts with respect thereto, public or private sales at any exchange, broker’s board, at any office of the Pledgee or elsewhere) at such prices or terms as the Pledgee may deem reasonable, for cash, upon credit or for future delivery, with the Pledgee having the right to purchase the whole or any part of the Pledged Property at any such public sale, all of the foregoing being free from any right or equity of redemption of the Pledgor, which right or equity of redemption is hereby expressly waived and released by the Pledgor (to the extent permitted by applicable law).  If notice of disposition of Pledged Property is required by law, ten (10) days prior notice by the Pledgee to the Pledgor designating the time and place of any public sale or the time after which any private sale or other intended disposition of Pledged Property is to be made, shall be deemed to be reasonable notice thereof and any other notice.  The Pledgee shall apply the cash proceeds of Pledged Property actually received by the Pledgee from any sale, lease, foreclosure or other disposition of the Pledged Property to payment of the Obligations then due, in whole or in part and in accordance with the terms of Section 10 of the Credit Agreement, and thereafter may hold such proceeds as cash collateral for the Obligations not then due.  The Pledgor shall remain liable to the Pledgee and the Secured Parties for the payment of any deficiency with interest at the highest rate provided for in the Credit Agreement and agrees to indemnify the Pledgee and the Secured Parties from all costs and expenses of collection or enforcement incurred in good faith by each of them or on their behalf, including reasonable attorneys’ fees and expenses, as provided in the Credit Agreement.
 
-6-

 
(c)            The Pledgor recognizes that the Pledgee may be unable to effect a public sale of all or part of the Pledged Property by reason of certain prohibitions contained in the Securities Act of 1933, as amended, as now or hereafter in effect, or in applicable Blue Sky or other state securities law, as now or hereafter in effect, but may be compelled to resort to one or more private sales to a restricted group of purchasers who will be obliged to agree, among other things, to acquire such Pledged Property for their own account for investment and not with a view to the distribution or resale thereof.  If at the time of any sale of the Pledged Property or any part thereof, the same shall not, for any reason whatsoever, be effectively registered under the Securities Act of 1933 (or other applicable state securities law), as then in effect, the Pledgee in its sole and absolute discretion is authorized to sell such Pledged Property or such part thereof by private sale in such manner and under such circumstances as the Pledgee or its counsel may deem necessary or advisable in order that such sale may legally be effected without registration.  The Pledgor agrees that private sales so made may be at prices and other terms less favorable to the seller than if such Pledged Property were sold at public sale, and that the Pledgee has no obligation to delay the sale of any such Pledged Property for the period of time necessary to permit the Issuer, even if the Issuer would agree, to register such Pledged Property for public sale under such applicable securities laws.  The Pledgor agrees that any private sales made under the foregoing circumstances shall be deemed to have been made in a commercially reasonable manner.
 
(d)            All of the rights and remedies of the Pledgee and the Secured Parties, including, but not limited to, the foregoing and those otherwise arising under this Agreement, the Credit Agreement and the other Loan Documents, the instruments comprising the Pledged Property, applicable law or otherwise, shall be cumulative and not exclusive and shall be enforceable alternatively, successively or concurrently as the Pledgee may deem expedient.  No failure or delay on the part of the Pledgee or any Secured Party in exercising any of its options, powers or rights or partial or single exercise thereof, shall constitute a waiver of such option, power or right.
 
8.              JURY TRIAL WAIVER; OTHER WAIVERS AND CONSENTS; GOVERNING LAW
 
(a)            The validity, interpretation and enforcement of this Agreement and any dispute arising out of the relationship between the Pledgor and the Pledgee or any Secured Party, whether in contract, tort, equity or otherwise, shall be governed by the laws of the State of New York, including, without limitation, Section 5-1401 of the New York General Obligations Law.
 
(b)            The Pledgor hereby irrevocably consents and submits to the non-exclusive jurisdiction of the Supreme Court of the State of New York, sitting in the Borough of Manhattan, The City of New York and the United States District Court for the Southern District of New York, whichever the Pledgee may elect, and waives any objection based on venue or forum non conveniens with respect to any action instituted therein arising under this Agreement or any of the other Loan Documents or in any way connected with or related or incidental to the dealings of the Pledgor and the Pledgee or any Secured Party in respect of this Agreement or any of the other Loan Documents or the transactions related hereto or thereto, in each case whether now existing or hereafter arising, and whether in contract, tort, equity or otherwise, and agrees that any dispute with respect to any such matters shall be heard only in the courts described above (except that the Pledgee and the Secured Parties shall have the right to bring any action or proceeding against the Pledgor or its property in the courts of any other jurisdiction that the Pledgee deems necessary or appropriate in order to realize on any collateral at any time granted by the Pledgor to the Pledgee or any Secured Party or to otherwise enforce its rights against the Pledgor or its property).

(e)            All references to the plural herein shall also mean the singular and to the singular shall also mean the plural.  All references to the Pledgor, the Pledgee, any Secured Party and the Issuer pursuant to the definitions set forth in the recitals hereto, or to any other person herein, shall include their respective successors and assigns.  The words “hereof,” “herein,” “hereunder,” “this Agreement” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not any particular provision of this Agreement and as this Agreement now exists or may hereafter be amended, modified, supplemented, extended, renewed, restated or replaced.
 
(f)            This Agreement shall be binding upon the Pledgor and its respective successors and assigns and shall inure to the benefit of and be enforceable by the Pledgee and the Secured Parties and their respective successors, endorsees, transferees and assigns, except that no Pledgor may assign its rights under this Agreement without the prior written consent of the Pledgee and the Secured Parties.  Any such purported assignment without such express prior written consent shall be void.  The liquidation, dissolution or termination of the Pledgor shall not terminate this Pledge. The terms and provisions of this Agreement are for the purpose of defining the relative rights and obligations of the Pledgor, the Pledgee and the Secured Parties with respect to the transactions contemplated hereby and there shall be no third party beneficiaries of any of the terms and provisions of this Agreement.
 
(g)            If any provision of this Agreement is held to be invalid or unenforceable, such invalidity or unenforceability shall not invalidate this Agreement as a whole, but this Agreement shall be construed as though it did not contain the particular provision held to be invalid or unenforceable and the rights and obligations of the parties shall be construed and enforced only to such extent as shall be permitted by applicable law.
 
(h)            This Agreement, any supplements hereto, and any instruments or documents delivered or to be delivered in connection herewith, represents the entire agreement and understanding of the parties hereto concerning the subject matter hereof, and supersedes all other prior agreements, understandings, negotiations and discussions, commitments, proposals, offers and contracts concerning the subject matter hereof, whether oral or written.  In the event of any inconsistency between the terms of this Agreement and any exhibit hereto, the terms of this Agreement shall govern.
 
(i)            Neither this Agreement nor any provision hereof shall be amended, modified, waived or discharged orally or by course of conduct, but only by a written agreement signed by an authorized officer of the Pledgee.  The Pledgee shall not by any act, delay, omission or otherwise be deemed to have expressly or impliedly waived any of its rights, powers and/or remedies unless such waiver shall be in writing and signed by an authorized officer of the Pledgee.  Any such waiver shall be enforceable only to the extent specifically set forth therein.  A waiver by the Pledgee of any right, power and/or remedy on any one occasion shall not be construed as a bar to or waiver of any such right, power and/or remedy that the Pledgee would otherwise have on any future occasion, whether similar in kind or otherwise.

(j)            This Agreement may be executed in any number of counterparts, each of which shall be an original, but all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of this Agreement by telefacsimile or electronic delivery shall have the same force and effect as the delivery of an original executed counterpart of this Agreement.  Any party delivering an executed counterpart of this Agreement by telefacsimile or electronic transmission shall also deliver an original executed counterpart, but the failure to do so shall not affect the validity, enforceability or binding effect of this Agreement.
 
(k)            The Pledgor agrees that, if pursuant to Section 9.16 of the Credit Agreement, it shall be required to cause a Subsidiary to become a pledgor hereunder, or if for any reason the Pledgor desires any such Subsidiary to become a pledgor hereunder, such Subsidiary shall execute and deliver to Pledgee a Pledge Agreement Supplement in substantially the form of Exhibit A (a “ Pledge Supplement ”) attached hereto and shall thereafter for all purposes be a party hereto and have the same rights, benefits and obligations as a pledgor party hereto as if originally named as a pledgor herein.  The rights and obligations of the Pledgor hereunder shall remain in full force and effect notwithstanding the addition of any new pledgor as a party to this Agreement.
