(b) Without limiting the generality of Section 5(a) hereof, the Company hereby irrevocably authorizes and empowers the Indenture Trustee for the ratable benefit of the Noteholders, upon the occurrence and during the continuation of any Event of Default, at the expense of the Company, either in the Indenture Trustee's own name or in the name of the Company, at any time and from time to time: (i) to ask, demand, receive, issue a receipt for, give acquittance for, settle and compromise any and all monies which may be or become due or payable or remain unpaid at any time or times to the Company, and any and all other property which may be or become deliverable at any time or times to the Company, under or with respect to the Collateral; (ii) to exercise any rights or remedies of the Company under the TARC Loan Documents and the TransTexas Loan Documents; (iii) to endorse any drafts, checks, orders or other instruments for the payment of money payable to the Company on account of the Collateral (including any such draft, check, order or instrument issued by any insurance company payable jointly to the Company and the Indenture Trustee); and (iv) to settle, compromise, prosecute or defend any action, claim or proceeding, or take any other action, all either in its own name or in the name of the Company or otherwise, which the Indenture Trustee may deem to be necessary or advisable for the purpose of exercising and enforcing its powers and rights under this Agreement or in furtherance of the purposes hereof, including any action which by the terms of this Agreement is to be taken by the Company. (c) Nothing in this Agreement shall be construed as requiring or obligating the Indenture Trustee to make any commitment or to make any inquiry as to the nature or sufficiency of any payment received by it, or to present or file any claim or notice, or to take any other action with respect to any of the Collateral or any part thereof or the amounts due or to become due in respect thereof or any property covered thereby, or to collect or enforce the payment of any amounts assigned to it or to which it may otherwise be entitled hereunder at any time or times other than to account for amounts or Collateral received. (d) The Indenture Trustee shall be entitled at any time to file this Agreement, or a carbon, photographic or any other reproduction of this Agreement, as a financing statement, but the failure of the Indenture Trustee to do so shall not impair the validity or enforceability of this Agreement. The Indenture Trustee shall have no duty to comply with any recording, filing or other legal requirements necessary to establish or maintain the validity, priority or enforceability of, or the Indenture Trustee's rights in or to, any of the Collateral. (e) In its discretion, the Indenture Trustee may discharge taxes and other encumbrances at any time levied or placed on any of the Collateral, make repairs thereto and pay any necessary filing fees. The Company agrees to reimburse the Indenture Trustee on demand 10 12 for any and all reasonable expenditures so made with interest on unpaid amounts at the maximum rate permitted by law. The Indenture Trustee shall have no obligation to the Company to make any such expenditures, nor shall the making thereof relieve the Company of any default. (f) Anything herein to the contrary notwithstanding, the Company shall remain liable under each contract or agreement comprised in the Collateral to be observed or performed by the Company thereunder. The Indenture Trustee shall not have any obligation or liability under any such contract or agreement by reason of or arising out of this Agreement or the receipt by the Indenture Trustee of any payment relating to any of the Collateral, nor shall the Indenture Trustee be obligated in any manner to perform any of the obligations of the Company under or pursuant to any such contract or agreement, to make inquiry as to the nature or sufficiency of any payment received by the Indenture Trustee in respect of the Collateral or as to the sufficiency of any performance by any party under any such contract or agreement, to present or file any claim, to take any action to enforce any performance or to collect the payment of any amounts which may have been assigned to the Indenture Trustee or to which the Indenture Trustee may be entitled at any time or times other than to account for amounts or Collateral received, and no action taken or omitted shall give rise to any defense, counterclaim or right of action against the Indenture Trustee, unless the Indenture Trustee's actions are taken or omitted to be taken with gross negligence or bad faith or constitute willful misconduct. The Indenture Trustee's sole duty with respect to the custody, safe keeping and physical preservation of the Collateral in its possession, under Section 9-207 of the UCC or otherwise, shall be to deal with such Collateral in the same manner as the Indenture Trustee deals with similar property for its own account. (g) If an Event of Default has occurred and is continuing, the Indenture Trustee may at any time, at its option, transfer to itself or any nominee any securities constituting the Pledged Collateral, receive any income thereon and hold such income as additional Collateral or apply it to the Indebtedness. Regardless of whether any Indebtedness is due, the Indenture Trustee may demand, sue for, collect, or make any settlement or compromise which it deems desirable with respect to the Collateral. Regardless of the adequacy of Collateral or any other security for the Indebtedness, any deposits or other sums at any time credited by or due from the Indenture Trustee to the Company may at any time be applied to or set off against any of the Indebtedness. (h) If an Event of Default shall have occurred and be continuing, the Company shall, at the request of the Indenture Trustee, notify obligors on chattel paper and general intangibles of the Company and obligors on instruments for which the Company is an obligee of the security interest of the Indenture Trustee in any chattel paper, general intangible or instrument and that payment thereof is to be made directly to the Indenture Trustee or to any financial institution designated by the Indenture Trustee as the Indenture Trustee's agent therefor, and the Indenture Trustee may itself, if an Event of Default shall have occurred and be continuing, without notice to or demand upon the Company, so notify said obligors. After the making of such a request or the giving of any such notification, the Company shall hold any proceeds of collection of chattel paper, general intangibles and instruments received by the Company as trustee for the Indenture Trustee without commingling the same with other funds of the Company and shall turn the same over to the Indenture Trustee in the identical form received, together with any necessary endorsements or assignments. The Indenture Trustee shall apply the proceeds of collection of chattel paper, general intangibles and instruments received by the Indenture Trustee to the Indebtedness, such proceeds to be immediately entered after final payment in cash of the items giving rise to them. 11 13 Section 6.Voting Rights, Dividends, Etc. (a) Until an Event of Default shall have occurred and be continuing: (i) except as otherwise provided in this Agreement, the Company shall be entitled to exercise any and all voting or consensual rights and powers, including subscription rights, in relation to the Pledged Collateral; provided, however, that no vote shall be cast or consent, waiver or ratification given or action taken which would materially impair the securities or the value thereof or violate any provision of this Agreement, the Indenture or any other ancillary document; (ii) except as otherwise provided in this Agreement, the Company shall be entitled to receive and retain any and all dividends, distributions or other payments in respect of the Pledged Collateral and the Indenture Trustee, upon receipt of any of the foregoing, shall promptly pay or distribute the same to the Company, and, to the extent so permitted, any distributions received by the Company and transferred to other persons shall pass free and clear of the lien and security interest hereof; and (iii) the Indenture Trustee shall execute and deliver to the Company or cause to be executed and delivered to the Company, all such proxies, powers of attorney, dividend orders and other instruments as the Company may reasonably request for the purpose of enabling it to exercise the voting or consensual rights and powers which the Company is entitled to exercise pursuant to the foregoing Section 6(a)(i) or to receive the dividends, distributions or other payments which the Company is authorized to retain pursuant to the foregoing Section 6(a)(ii). (b) Upon the occurrence and during the continuance of an Event of Default, all rights of the Company to exercise the voting or consensual rights and powers which the Company would otherwise be entitled to exercise pursuant to Section 6(a)(i) and to receive the dividends, distributions and other payments which the Pledgor would otherwise be authorized to receive and retain pursuant to Section 6(a)(ii) shall automatically cease, and all such rights shall thereupon become vested in the Indenture Trustee, which shall then have the sole and exclusive right and authority to exercise, in its sole discretion, all such voting and consensual rights and powers and to receive and retain as Collateral all such dividends, distributions and other payments. Without limiting the foregoing, in such event the Indenture Trustee may exercise all voting and corporate rights at any meeting of any corporation issuing any such securities and any and all rights of conversion, exchange, subscription or any other rights, privileges or options pertaining to any such securities as if it were the absolute owner thereof, including, without limitation, the rights to exchange at its discretion, any and all such securities upon the merger, consolidation, reorganization, recapitalization or other readjustment of any corporation issuing any such securities or upon the exercise by any such issuer or the Indenture Trustee of any right, privilege or option pertaining to any such securities, and, in connection therewith, to deposit and deliver any and all securities with any committee, depository, transfer agent, registrar or other designated agency upon such terms and conditions as it may determine, all without liability except to account for the property actually received by it, but the Indenture Trustee shall have no duty to exercise any of the aforesaid rights, privileges or options and the Indenture Trustee shall not be responsible for any failure to do so or delay in so doing. Section 7. Default. 12 14 (a) It shall constitute a Default or an Event of Default under this Agreement if a "Default" or an "Event of Default" shall occur under the Indenture. (b) If an Event of Default shall have occurred and is continuing and if the maturity of the Notes is accelerated under the provisions of the Indenture, in addition to any other rights and remedies that may be available to the Indenture Trustee under the UCC or the Indenture or under Section 5(a) or 5(b) of this Agreement or otherwise under this Agreement or at law, the Indenture Trustee, for the ratable benefit of the Noteholders, shall also have the following rights and powers: (i) The Indenture Trustee may, without being required to give any notice except as hereinafter provided, sell the Collateral, or any part thereof, at public or private sale, for cash, upon credit or for future delivery and at such price or prices as the Indenture Trustee deems satisfactory, and the Indenture Trustee and/or its collateral agent may be the purchaser for the ratable benefit of the Noteholders of any or all of the Collateral so sold at a public sale and thereafter hold the same absolutely free from any right or claim of whatsoever kind, and the Indebtedness or any portion of the Indebtedness may be applied as a credit against the purchase price. (ii) Upon any such sale, the Indenture Trustee shall have the right to deliver, assign and transfer to the purchaser thereof the Collateral so sold. Each purchaser at any such sale shall hold the property sold absolutely free from any claim or right of whatsoever kind by or on behalf of the Company, including any equity or rights of redemption of the Company, and the Company hereby specifically waives, to the full extent permitted by applicable law, all rights of redemption, stay or appraisal which it has or may have under any rule or law or statute now existing or hereafter adopted. (iii) The Indenture Trustee shall give the Company ten (10) business days' written notice (which the Company agrees is reasonable notification within the meaning of Section 9.504 of the UCC) of its intention to make any such public or private sale. Such notice, in case of public sale, shall state the time and place fixed for such sale and, in case of a private sale, shall state the date after which such sale is to be made. (iv) Any such public sale shall be held at such time or times within ordinary business hours and at such places as the Indenture Trustee may fix in the notices of such sale. At any such sale the Collateral may be sold in one lot as an entirety or in separate parcels, as the Indenture Trustee may, in its sole discretion, determine. (v) The Indenture Trustee shall not be obligated to make any sale of the Collateral if it shall determine not to do so, regardless of the fact that notice of sale of the Collateral may have been given. The Indenture Trustee may, without notice or publication, adjourn any public or private sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for the sale, and such sale may, without further notice, be made at any time or place to which the same shall be so adjourned. (vi) In case of any sale of all or any part of the Collateral on credit or for future delivery, the Collateral so sold may be retained by the Indenture Trustee until the selling price is paid by the purchaser thereof, but the Indenture Trustee shall not incur 13 15 any liability in case of the failure of such purchaser to take up and pay for the Collateral so sold and, in case of any such failure, such Collateral may again be sold upon like notice. (vii) The Indenture Trustee, instead of exercising the power of sale herein conferred upon it, may proceed by a suit or suits at law or in equity to exercise its remedies regarding the Collateral and sell the Collateral, or any portion thereof, under a judgment or decree of a court or courts of competent jurisdiction. (viii) The Company agrees that if any Event of Default shall have occurred and be continuing, then the Indenture Trustee shall have the right to take possession of the Collateral, and for that purpose the Indenture Trustee may, so far as the Company can give authority therefor, enter upon any premises on which the Collateral may be situated and remove the same therefrom with or without notice or process of law. The Company waives any and all rights that it may have to a judicial hearing in advance of the enforcement of any of the Indenture Trustee's rights hereunder, including, without limitation, its right following an Event of Default to take immediate possession of the Collateral and to exercise its rights with respect thereto. To the extent that any of the Obligations are to be paid or performed by a person other than the Company, the Company waives and agrees not to assert any rights or privileges which it may have under Section 9-112 of the UCC. (ix) If under mandatory requirements of applicable law, the Indenture Trustee shall be required to make disposition of the Collateral within a period of time that does not permit the giving of notice to the Company as hereinbefore provided, the Indenture Trustee need give the Company only such notice of disposition as shall be reasonably practicable in view of such mandatory requirements of law. (x) The Indenture Trustee may instruct the obligor or obligors on any agreement, instrument or other obligation constituting the Collateral, including the obligors under the Intercompany Notes, to make any payment or render any performance required by the terms of such agreement, instrument or obligation directly to the Indenture Trustee or its designee. (c) The Indenture Trustee shall incur no liability as a result of the sale of the Collateral, or any part thereof, at any private sale other than for its own gross negligence, willful misconduct or bad faith. The Company hereby waives, to the maximum extent permitted by applicable law, any claims against the Indenture Trustee and each Noteholder arising by reason of the fact that the price at which the Collateral may have been sold at such private sale was less than the price which might have been obtained at a public sale or was less than the aggregate amount of the Indebtedness, even if the Indenture Trustee accepts the first offer received and does not offer such Collateral to more than one offeree. (d) The Indenture Trustee shall not be obligated to pursue or exhaust its rights and remedies against any particular Collateral or other security for the Indebtedness before pursuing or enforcing its rights and remedies against any other Collateral or other security for the Indebtedness. 14 16 (e) To the extent permitted by law, the Company hereby waives (i) any rights to require the Indenture Trustee to proceed first against any other Person, to exhaust its rights in the Collateral or other security for the Indebtedness or to pursue any other right that the Indenture Trustee might have, (ii) with respect to the Notes, presentment and demand for payment, protest, notice of protest and nonpayment, notice of dishonor, notice of the intention to accelerate and notice of acceleration (except as otherwise set forth in the Indenture), and (iii) all rights of marshalling in respect of any and all of the Collateral. (f) Without precluding any other methods of sale, the Company acknowledges that the sale of the Collateral shall have been made in a commercially reasonable manner if conducted in conformity with reasonable commercial practices of banks disposing of similar property. The Indenture Trustee shall not be liable for any depreciation in the value of the Collateral. (g) The Company agrees that its obligation to deliver the Collateral is of the essence of this Agreement and that accordingly, upon application to a court of equity having jurisdiction, the Indenture Trustee shall be entitled to a decree requiring specific performance by the Company of such obligation. (h) Remedies of the Indenture Trustee are cumulative and the exercise of any one or more of the remedies provided herein shall not be construed as a waiver of any of the other remedies of the Indenture Trustee. (i) If an Event of Default shall have occurred and be continuing, the proceeds of any sale of or other realization upon all or any part of the Collateral and any other amounts held by the Indenture Trustee under this Agreement shall be applied by the Indenture Trustee as provided in the Indenture. Any amounts remaining after such applications and the payment in full of all Notes with respect to the Indebtedness shall be remitted to the Company, its successors or assigns, or as a court of competent jurisdiction may otherwise direct. Section 8. Registration Rights. (a) If the Indenture Trustee or the Noteholders shall determine to exercise the right to sell any or all of the Pledged Collateral pursuant to Section 7 hereof, and if in the opinion of counsel for the Indenture Trustee or the Noteholders it is necessary (or if in the opinion of the Indenture Trustee or the Noteholders it is advisable) to have the Pledged Collateral, or that portion thereof to be sold, registered under the provisions of the Securities Act of 1933, as amended (the "Securities Act"), the Company will cause each issuing corporation to execute and deliver, and cause the directors and officers of each thereof to execute and deliver, all at the Company's expense, all such instruments and documents, and to do or cause to be done all such other acts and things as may be necessary or, in the opinion of the Indenture Trustee or the Noteholders, advisable to register the Pledged Collateral, or that portion thereof to be sold, under the provisions of the Securities Act and to use its best efforts to cause the registration statement relating thereto to become effective and to remain effective for a period of one year from the date of the first public offering of the Pledged Collateral, or that portion thereof to be sold, and to make all amendments or supplements thereto and/or to the related prospectus which, in the opinion of the Indenture Trustee or the Noteholders, are necessary or advisable, all in conformity with the requirements of the Securities Act and the rules and regulations of the Securities and 15 17 Exchange Commission applicable thereto. The Company agrees to use its best efforts to cause each such issuing corporation to comply with the provisions of the securities or "Blue Sky" laws of any jurisdiction which the Indenture Trustee or the Noteholder shall designate and to cause each such issuing corporation to make available to its security holders, as soon as practicable, an earnings statement (which need not be audited) which will satisfy the provisions of Section 11(a) of the Securities Act. (b) The Company recognizes that the Indenture Trustee or the Noteholders may be unable, or find it undesirable, to effect a public sale of any or all the Pledged Collateral by reason of certain prohibitions contained in the Securities Act and applicable state securities laws or otherwise, but may be compelled or desire to resort to one or more private sales thereof to a restricted group of purchasers who will be obliged to agree, among other things, to acquire such securities for their own account for investment and not with a view to the distribution or resale thereof in violation of the Securities Act. The Company acknowledges and agrees that any such private sale may result in prices and other terms less favorable to the seller than if such sale were a public sale, but, notwithstanding such circumstances, such private sale shall be deemed to have been made in a commercially reasonable manner. The Indenture Trustee and the Noteholders shall be under no obligation to delay a sale of any of the Pledged Collateral for the period of time necessary to permit the issuing corporation of such securities to register such securities for public sale under the Securities Act, or under applicable state securities laws, even if the issuing corporation would agree to do so. (c) The Company further agrees to use commercially reasonable efforts to do or cause to be done all such other acts and things as may be necessary to make such sale or sales of any portion or all of the Pledged Collateral valid and binding and in compliance with any and all applicable laws, regulations, orders, writs, injunctions, decrees or awards of any and all courts, arbitrators or governmental instrumentalities, domestic or foreign, having jurisdiction over any such sale or sales, all at the Company's expense. The Company further agrees that a breach of any of the covenants contained in this Section 8 will cause irreparable injury to the Noteholders, that the Indenture Trustee and the Noteholders have no adequate remedy at law in respect of such breach and, as a consequence, agrees that each and every covenant contained in this Section 8 shall be specifically enforceable against the Company, and the Company hereby waives and agrees not to assert any defenses against an action for specific performance of such covenants except for a defense that no Event of Default has occurred under the Indenture. (d) In addition, the Company agrees to enter into, and to cause TransTexas to enter into, a Registration Rights Agreement, by and among the Company, TransTexas and the Indenture Trustee, satisfactory in both form and substance to both the Company and the Indenture Trustee, within 60 days of the date of this Agreement. Section 9. General Provisions. (a) Continuing Security Interest; Binding Effect. This Agreement shall create a continuing security interest in the Collateral and shall (a) remain in full force and effect until termination of the obligations of the Indenture Trustee under the Indenture and the indefeasible payment in full thereafter of the Obligations; (b) be binding upon the Company and its successors and assigns; and (c) inure to the benefit of the Indenture Trustee for the benefit of the Noteholders and their respective successors, transferees and assigns. Without limiting the generality of the foregoing clause (c), the Indenture Trustee may assign or otherwise transfer any 16 18 of its rights under this Agreement to any other Person, and such Person shall thereupon become vested with all the benefits in respect thereof granted herein or otherwise to the Indenture Trustee. Upon the termination of the obligations of the Indenture Trustee under the Indenture and the indefeasible payment in full thereafter of the Obligations, the Company shall be entitled to the return, upon its request and at its expense, of such of the Collateral as is in the Indenture Trustee's possession and as shall not have been sold or otherwise disposed of pursuant to the terms hereof. (b) Security Interest Absolute. The lien and security interest created hereunder and the Company's obligations hereunder and the Indenture Trustee's rights hereunder shall not be released, diminished, impaired or adversely affected by the occurrence of any one or more of the following events: (i) The taking or accepting of any other security or assurance for any or all of the Indebtedness; (ii) Any release, surrender, exchange, subordination or loss of any security or assurance at any time existing in connection with any or all of the Indebtedness; (iii) The modification of, amendment to, or waiver of compliance with any terms of the Indenture, the Notes, the TARC Loan Documents or the TransTexas Loan Documents; (iv) Any renewal, extension and/or rearrangement of the payment of any or all of the Indebtedness or any statement, indulgence, forbearance or compromise that may be granted or given by the Indenture Trustee to the Company or any other Person; (v) any neglect, delay, omission, failure or refusal of the Indenture Trustee to take or prosecute any action in connection with any agreement, document or other instrument evidencing, securing or assuring the payment of any or all of the Indebtedness; (vi) the illegality, invalidity or unenforceability of all or any part of the Indenture, the Notes, the TARC Loan Documents or the TransTexas Loan Documents; or (vii) any other circumstance (other than payment in full of the Obligations) that might otherwise constitute a defense available to, or a discharge of, the Company or any party to any document in respect of the Obligations. (c) Amendments. This Agreement or any term hereof may be amended or changed only by an instrument in writing executed jointly by the Company and the Indenture Trustee and in accordance with Article IX of the Indenture. (d) Remedies Cumulative. Each right, power and remedy herein specifically granted to the Indenture Trustee or otherwise available to it or now or hereafter existing in law or in equity shall be cumulative and concurrent, and shall be in addition to every other right, power and remedy herein specifically given or now or hereafter existing at law, in equity, or otherwise (including, without limitation, all rights, powers and remedies granted to a secured party under 17 19 the UCC), and each such right, power and remedy, whether specifically granted herein or otherwise existing, may be exercised at any time and from time to time as often and in such order as may be deemed expedient by the Indenture Trustee in its sole and complete discretion. The provisions of this Agreement may only be waived by an instrument in writing signed by the Indenture Trustee, and no failure on the part of the Indenture Trustee to exercise, and no delay in exercising, and no course of dealing with respect to, any such right, power or remedy, shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right. No notice to or demand on the Company hereunder shall, of itself, entitle the Company to any other or further notice or demand in the same or similar circumstances. (e) Assignment. Neither this Agreement nor any interest herein or in the Collateral, or any part thereof, may be assigned by the Company without the prior written consent of the Indenture Trustee, except as expressly permitted herein or in the Indenture or in the Disbursement Agreement. (f) Headings. The descriptive headings of the several sections of this Agreement are inserted for convenience only and shall not control or affect the meaning or construction of any of the provisions hereof. (g) Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof or affecting the validity of enforceability or such provision in any other jurisdiction. (h) Survival. All representations and warranties contained herein, in the Indenture or made in writing by the Company in connection herewith or therewith, shall survive the execution and delivery of this Agreement, the Indenture and any documents executed in connection herewith or therewith.

A complete set of counterparts shall be lodged with the Indenture Trustee. (j) Waiver. To the extent permitted by applicable law the Company hereby waives promptness, diligence, notice of acceptance and any other notice with respect to any of the Indenture obligations and this Agreement and any requirement that the Indenture Trustee protect, secure, perfect or insure any security interest or any property subject thereto or exhaust any right or take any action against the Company or any other person or entity; provided however, that the Indenture Trustee shall in any event take such care in the handling of any Collateral in its possession as it takes with respect to its own property of a similar nature in its possession. (k) Notices. Any notices or other communications required or permitted hereunder shall be in writing, and shall be sufficiently given if made by hand delivery, by telex, by facsimile or registered or certified mail, postage prepaid, return receipt requested, addressed as provided in Section 13.2 of the Indenture.

The Company may give notice to the Noteholders at the addresses set forth for them in the register kept by the Registrar under the Indenture or may request that the Indenture Trustee notify the Noteholders at such address. (l) Conflicting Terms. In the event of any conflict or inconsistency between the terms, covenants, conditions and provisions set forth in this Agreement and the terms, covenants, conditions and provisions set forth in the Indenture, the terms, covenants, conditions and provisions of the Indenture shall prevail. (m) Release. The Collateral, in whole or in part, may be released in accordance with the Indenture. (n) Conflicts. If any provision of the Indenture limits, qualifies, or conflicts with any similar provision of this Agreement, such provision of the Indenture shall control. (o) Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW EXCEPT SECTION 5-1401 OF THE NEW YORK GENERAL OBLIGATIONS LAW.
