                 than 30 days after the date notice thereof is mailed to the
                 Holders (or longer if required by applicable law);





                                       4
   5
                          (iii)   utilize the services of a depository for the
                 Exchange Offer with an address in the Borough of Manhattan,
                 The City of New York;

                          (iv)    permit Holders to withdraw tendered Notes at
                 any time prior to the close of business, New York time, on the
                 last Business Day on which the Exchange Offer shall remain
                 open; and

                          (v)     otherwise comply with all laws applicable to
                 the Exchange Offer.

                 (d)      As soon as practicable after the close of the
         Exchange Offer, the Company shall:

                          (i)     accept for exchange all Notes validly
                 tendered and not validly withdrawn pursuant to the Exchange
                 Offer;

                          (ii)    deliver to the Trustee for cancellation all
                 Notes so accepted for exchange; and

                          (iii)   cause the Trustee promptly to authenticate
                 and deliver to each Holder of Notes, Exchange Securities equal
                 in aggregate principal amount to the Notes of such Holder so
                 accepted for exchange.

                 (e)      Interest on each Exchange Security and Private
         Exchange Security will accrue (or principal will accrete, as
         applicable) from the last interest payment date on which interest was
         paid on the Notes surrendered in exchange therefor or, if no interest
         has been paid on the Notes, from the date of original issue of the
         Notes.  Each Exchange Security and Private Exchange Security shall
         bear interest at the rate set forth thereon; provided, that interest
         with respect to the period prior to the issuance thereof shall accrue
         at the rate or rates borne by the Notes from time to time during such
         period.

                 (f)      The Company shall include within the Prospectus
         contained in the Exchange Offer Registration Statement a section
         entitled "Plan of Distribution," containing a summary statement of the
         positions taken or policies made by the staff of the SEC with respect
         to the potential "underwriter" status of any broker-dealer that is the
         beneficial owner (as defined in Rule 13d-3 under the Exchange Act) of
         Exchange Securities received by such broker-dealer in the Exchange
         Offer (a "Participating Broker-Dealer").  Such "Plan of Distribution"
         section shall also allow the use of the Prospectus by all Persons
         subject to the prospectus delivery requirements of the Securities Act,
         including (without limitation) all Participating Brokers-Dealers, and
         include a statement describing the means by which Participating
         Broker-Dealers may resell the Exchange Securities.  The Company shall
         use its best efforts to keep the Exchange Offer Registration Statement
         effective and to amend and supplement the Prospectus to be lawfully
         delivered by all Persons subject to the prospectus delivery
         requirement of the Securities Act for such period of time as such
         Persons must comply with such requirements in order to resell the
         Exchange Securities; provided that such period shall not exceed 180
         days after consummation of the Exchange Offer (as such period may be
         extended pursuant to the last paragraph of Section 6 (the "Applicable
         Period")).

                 (g)      If, prior to consummation of the Exchange Offer, the
         Purchaser holds any Securities acquired by it and having the status as
         an unsold allotment in the initial distribution, the Company shall,
         upon the request of the Purchaser, simultaneously with the delivery of
         the





                                       5
   6
         Exchange Securities in the Exchange Offer, issue (pursuant to the same
         indenture as the Exchange Securities) and deliver to the Purchaser, in
         exchange for the Securities held by the Purchaser (the "Private
         Exchange"), a like principal amount of debt securities of the Company
         that are identical to the Exchange Securities (the "Private Exchange
         Securities").  The Private Exchange Securities shall bear the same
         CUSIP number as the Exchange Securities.

                 (h)      The Company may require each Holder participating in
         the Exchange Offer to represent to the Company that at the time of the
         consummation of the Exchange Offer (i) any Exchange Securities
         received by such Holder in the Exchange Offer will be acquired in the
         ordinary course of its business, (ii) such Holder will have no
         arrangement or understanding with any Person to participate in the
         distribution of the Exchange Securities within the meaning of the
         Securities Act or resale of the Exchange Securities in violation of
         the Securities Act, (iii) if such Holder is not a broker-dealer, that
         it is not engaged in and does not intend to engage in, the
         distribution of the Exchange Securities, (iv) if such Holder is a
         broker-dealer that will receive Exchange Securities for its own
         account in exchange for Notes that were acquired as a result of
         market- making or other trading activities, that it will deliver a
         prospectus, as required by law, in connection with any resale of such
         Exchange Securities and (v) if such Holder is an affiliate of the
         Company, that it will comply with the registration and prospectus
         delivery requirements of the Securities Act applicable to it.

                 (i)      If (i) prior to the consummation of the Exchange
         Offer, either the Company or the Holders of a majority in aggregate
         principal amount of Registrable Securities determines in its or their
         reasonable judgment that (A) the Exchange Securities would not, upon
         receipt, be tradeable by the Holders thereof without restriction under
         the Securities Act and the Exchange Act and without material
         restrictions under applicable Blue Sky or state securities laws, or
         (B) the interests of the Holders under this Agreement, taken as a
         whole, would be materially adversely affected by the consummation of
         the Exchange Offer, (ii) applicable interpretations of the staff of
         the SEC would not permit the consummation of the Exchange Offer prior
         to 90 days after the Effectiveness Date, (iii) subsequent to the
         consummation of the Private Exchange but within one year of the
         Closing Date, the Purchaser so requests, (iv) the Exchange Offer is
         not consummated within 270 days of the Closing Date for any reason or
         (v) in the case of any Holder not permitted to participate in the
         Exchange Offer or of any Holder participating in the Exchange Offer
         that receives Exchange Securities that may not be sold without
         material restriction under state and federal securities laws (other
         than due solely to the status of such Holder as an affiliate of the
         Company within the meaning of the Securities Act) and, in either case
         contemplated by this clause (v), such Holder notifies the Company
         within six months of consummation of the Exchange Offer, then the
         Company shall promptly deliver to the Holders (or in the case of any
         occurrence of the event described in clause (v) of this Section 2(i),
         to any such Holder) and the Trustee notice thereof (the "Shelf
         Notice") and shall as promptly as possible thereafter file an Initial
         Shelf Registration pursuant to Section 3.

         3.      Shelf Registration.  If a Shelf Notice is required to be
delivered pursuant to Section 2(i)(i), (ii), (iii) or (iv),  then this Section
3 shall apply to all Registrable Securities.  Otherwise, upon consummation of
the Exchange Offer in accordance with Section 2, the provisions of this Section
3 shall apply solely with respect to (i) Notes held by any Holder thereof not
permitted to participate in the Exchange Offer and (ii) Exchange Securities
that are not freely tradeable as contemplated by Section 2(i)(v).





                                       6
   7
                 (a)      Initial Shelf Registration.  The Company shall use
         its best efforts to prepare and file with the SEC a Registration
         Statement for an offering to be made on a continuous basis pursuant to
         Rule 415 covering all of the Registrable Securities (the "Initial
         Shelf Registration").  If the Company has not yet filed an Exchange
         Offer Registration Statement, the Company shall use its best efforts
         to file with the SEC the Initial Shelf Registration on or prior to the
         Filing Date.  Otherwise, the Company shall use its best efforts to
         file the Initial Shelf Registration within 20 days of the delivery of
         the Shelf Notice or as promptly as possible following the request of
         the Purchaser.  The Initial Shelf Registration shall be on Form S-1 or
         another appropriate form permitting registration of such Registrable
         Securities for resale by such holders in the manner or manners
         designated by them (including, without limitation, one or more
         underwritten offerings).  The Company shall (i) not permit any
         securities other than the Registrable Securities to be included in any
         Shelf Registration, and (ii) use its best efforts to cause the Initial
         Shelf Registration to be declared effective under the Securities Act
         as promptly as practicable after the filing thereof and to keep the
         Initial Shelf Registration continuously effective under the Securities
         Act until the date that is 24 months from the Effectiveness Date
         (subject to extension pursuant to the last paragraph of Section 6)
         (the "Effectiveness Period"), or such shorter period ending when (i)
         all Registrable Securities covered by the Initial Shelf Registration
         have been sold or (ii) a Subsequent Shelf Registration covering all of
         the Registrable Securities has been declared effective under the
         Securities Act.

                 (b)      Subsequent Shelf Registrations.  If any Shelf
         Registration ceases to be effective for any reason at any time during
         the Effectiveness Period (other than because of the sale of all of the
         Registrable Securities registered thereunder), the Company shall use
         its best efforts to obtain the prompt withdrawal of any order
         suspending the effectiveness thereof, and in any event shall within 30
         days of such cessation of effectiveness amend the Shelf Registration
         in a manner reasonably expected to obtain the withdrawal of the order
         suspending the effectiveness thereof, or file an additional "shelf"
         Registration Statement pursuant to Rule 415 covering all of the
         Registrable Securities (a "Subsequent Shelf Registration").  If a
         Subsequent Shelf Registration is filed, the Company shall use its best
         efforts to cause the Subsequent Shelf Registration to be declared
         effective as soon as practicable after such filing and to keep such
         Subsequent Shelf Registration continuously effective for a period
         equal to the number of days in the Effectiveness Period less the
         aggregate number of days during which the Initial Shelf Registration,
         and any Subsequent Shelf Registration, was previously effective.

         4.      Liquidated Damages.

                 (a)      The Company acknowledges and agrees that the holders
         of Registrable Securities will suffer damages, and that it would not
         be feasible to ascertain the extent of such damages with precision, if
         the Company fails to fulfill its obligations hereunder.  Accordingly,
         in the event of such failure, the Company agrees to pay liquidated
         damages to each Holder under the circumstances and to the extent set
         forth below:

                          (i)      if neither the Exchange Offer Registration
                 Statement nor the Initial Shelf Registration has been filed
                 with the SEC on or prior to the Filing Date; or

                          (ii)    if neither the Exchange Offer Registration
                 Statement nor the Initial Shelf Registration is declared
                 effective by the SEC on or prior to the Effectiveness Date; or





                                       7
   8
                          (iii)   if the Company has not accepted for exchange
                 Exchange Securities for all Notes validly tendered in
                 accordance with the terms of the Exchange Offer within 30 days
                 after the date on which an Exchange Offer Registration
                 Statement is declared effective by the SEC; or

                          (iv)    if a Shelf Registration is filed and declared
                 effective by the SEC but thereafter ceases to be effective
                 without being succeeded within 30 days by a Subsequent Shelf
                 Registration filed and declared effective;

         (each of the foregoing a "Registration Default," and the date on which
         the Registration Default occurs being referred to herein as a
         "Registration Default Date").

                          Upon the occurrence of any Registration Default, the
         Company shall be obligated to pay, or cause to be paid, in addition to
         amounts otherwise due under the Indenture and the Registrable
         Securities, as liquidated damages, and not as a penalty, to each
         holder of a Registrable Security, an additional amount (the "Weekly
         Liquidated Damages Amount") equal to (A) for each weekly period
         beginning on the Registration Default Date for the first 120-day
         period immediately following such Registration Default Date, $0.05 per
         week per $1,000 principal amount of Registrable Securities held by
         such holder, and (B) for each weekly period beginning with the first
         full week after the 120-day period set forth in the foregoing clause
         (A), $0.15 per week per $1,000 principal amount of Registrable
         Securities held by such holder; provided that such liquidated damages
         will, in each case, cease to accrue (subject to the occurrence of
         another Registration Default) on the date on which all Registration
         Defaults have been cured.  A Registration Default under clause (i)
         above shall be cured on the date that either the Exchange Offer
         Registration Statement or the Initial Shelf Registration is filed with
         the SEC; a Registration Default under clause (ii) above shall be cured
         on the date that either the Exchange Offer Registration Statement or
         the Initial Shelf Registration is declared effective by the SEC; a
         Registration Default under clause (iii) above shall be cured on the
         earlier of the date (A) the Exchange Offer is consummated with respect
         to all Notes validly tendered or (B) the Company delivers a Shelf
         Notice to the Holders; and a Registration Default under clause (iv)
         above shall be cured on the earlier of (A) the date on which the
         applicable Shelf Registration is no longer subject to an order
         suspending the effectiveness thereof or proceedings relating thereto
         or (B) a Subsequent Shelf Registration is declared effective.

                 (b)      The Company shall notify the Trustee within five
         Business Days after each Registration Default Date.  The Company shall
         pay the liquidated damages due on the Registrable Securities by
         depositing with the Trustee, in trust, for the benefit of the Holders
         thereof, by 12:00 noon, New York City time, on or before the
         semi-annual interest payment date for any of the Registrable
         Securities, immediately available funds in sums sufficient to pay the
         liquidated damages then due.  With respect to the Senior Secured Notes
         (and with respect to the Senior Secured Discount Notes after June 15,
         1999), the liquidated damages amount due shall be payable on each
         interest payment date to the Holder entitled to receive the interest
         payment to be made on such date as set forth in the Indenture.  With
         respect to the Senior Secured Discount Notes on or prior to June 15,
         1999, the liquidated damages amount due shall be payable on each June
         15 and December 15 to the Holder of record on the immediately
         preceding June 1 or December 1, respectively.

         5.      Hold-Back Agreements.  The Company agrees (i) without the
prior written consent of the Holders of a majority of the aggregate principal
amount of the then outstanding Securities, not to effect





                                       8
   9

Regulation D under the Securities Act) of any securities the same as or
substantially similar to those covered by a Registration Statement filed
pursuant to Section 2 or 3, or any securities convertible into or exchangeable
or exercisable for such securities, during the 10 days prior to, and during the
90-day period beginning on, (A) the effective date of any Registration
Statement filed pursuant to Sections 2 and 3, unless the Holders of a majority
in aggregate principal amount of Registrable Securities to be included in such
Registration Statement consent or (B) the commencement of an underwritten
public distribution of Registrable Securities, where the managing underwriter
so requests; and (ii) to cause each holder of such securities that are the same
as or substantially similar to Registrable Securities issued at any time after
the date of this Agreement (other than securities purchased in a registered
public offering) to agree, unless prevented by applicable statute or
regulation, not to effect any public sale or distribution of any such
securities during such periods, including a sale pursuant to Rule 144 or Rule
144A.

         6.      Registration Procedures.  In connection with the registration
of any Securities pursuant to Sections 2 or 3, the Company shall effect such
registrations to permit the sale of such Securities in accordance with the
intended method or methods of disposition thereof, and pursuant thereto the
Company shall:

                 (a)      Prepare and file with the SEC, as soon as practicable
         after the date hereof but in any event on or prior to the Filing Date,
         a Registration Statement or Registration Statements as prescribed by
         Section 2 or 3, and use its best efforts to cause each such
         Registration Statement to become effective and remain effective as
         provided herein; provided, that, if (i) such filing is pursuant to
         Section 3 or (ii) a Prospectus contained in an Exchange Offer
         Registration Statement filed pursuant to Section 2 is required to be
         delivered under the Securities Act by any Participating Broker-Dealer
         who seeks to sell Exchange Securities during the Applicable Period,
         before filing any Registration Statement or Prospectus or any
         amendments or supplements thereto, the Companies shall, if requested,
         furnish to and afford the Holders of the Registrable Securities
         covered by such Registration Statement, their Special Counsel, each
         Participating Broker-Dealer, the managing underwriters, if any, and
         their counsel, a reasonable opportunity to review and make available
         for inspection by such Persons copies of all such documents (including
         copies of any documents to be incorporated by reference therein and
         all exhibits thereto) proposed to be filed, such financial and other
         information and books and records of the Companies, and cause the
         officers, directors and employees of the Companies, Company counsel
         and independent certified public accountants of the Company, to
         respond to such inquiries, as shall be necessary, in the opinion of
         respective counsel to such holders, Participating Broker-Dealer and
         underwriters, to conduct a reasonable investigation within the meaning
         of the Securities Act.  The Company may require each Holder to agree
         to keep confidential any non-public information relating to the
         Company received by such Holder and not disclose such information
         (other than to an Affiliate or prospective purchaser who agrees to
         respect the confidentiality provisions of this Section 6(a)) until
         such information has been made generally available to the public
         unless the release of such information is required by law or necessary
         to respond to inquiries of regulatory authorities (including the
         National Association of Insurance Commissioners, or similar
         organizations or their successors).  The Company shall not file any
         Registration Statement or Prospectus or any amendments or supplements
         thereto in respect of which the Holders must be afforded an
         opportunity to review prior to the filing of such document, if the
         Holders of a majority in aggregate principal amount of the Registrable
         Securities covered by such Registration Statement, their Special
         Counsel, any Participating Broker-Dealer or the managing underwriters,
         if any, or their counsel shall reasonably object.

         Securities or the Exchange Securities, as the case may be, and cause
         the Indenture (or other indenture relating to the Registrable
         Securities) to be qualified under the TIA not later than the effective
         date of the first Registration Statement; and in connection therewith,

                 (c)      Prepare and file with the SEC such amendments and
         post-effective amendments to the Registration Statement as may be
         necessary to keep such Registration Statement continuously effective
         for the time periods required hereby; cause the related Prospectus to
         be supplemented by any Prospectus supplement required by applicable
         law, and as so supplemented to be filed pursuant to Rule 424 (or any
         similar provisions then in force) under the Securities Act; and comply
         in all material respects with the provisions of the Securities Act and
         the Exchange Act applicable thereto with respect to the disposition of
         all securities covered by such Registration Statement, as so amended,
         or in such Prospectus, as so supplemented, in accordance with the
         intended methods of distribution set forth in such Registration
         Statement or Prospectus as so amended.

                 (d)      Furnish to such selling Holders and Participating
         Broker-Dealers who so request (i) upon the Company's receipt, a copy

         number of copies of such Registration Statement and of each amendment
         and supplement thereto (in each case including any documents

         reasonable number of copies of the Prospectus included in such
         Registration Statement (including each preliminary Prospectus), and

         the Company pursuant to Rule 424(b) under the Securities Act, in

         other documents (including any amendments required to be filed

         Prospectus by each of the selling Holders of Registrable Securities or
         each such Participating Broker-Dealer, as the case may be, and the
         underwriters or agents, if any, and dealers (if any), in connection
         with the offering and sale of the Registrable Securities covered by,
         or the sale by Participating Broker- Dealers of the Exchange
         Securities pursuant to, such Prospectus and any amendment thereto.

                 (e)      If (A) a Shelf Registration is filed pursuant to
         Section 3 or (B) a Prospectus contained in an Exchange Offer
         Registration Statement filed pursuant to Section 2 is required to be
         delivered under the Securities Act by any Participating Broker-Dealer
         who seeks to sell Exchange Securities during the Applicable Period,
         notify the selling Holders of Registrable Securities, their Special
         Counsel, each Participating Broker- Dealer and the managing
         underwriters, if any, promptly (but in any event within two Business
         Days), and confirm such notice in writing, (i) when a Prospectus has
         been filed, and, with respect to a Registration Statement or any
         post-effective amendment, when the same has become effective under the
         Securities Act, (ii) of the issuance by the SEC of any stop order
         suspending the effectiveness of a Registration Statement or of any
         order preventing or suspending the use of any Prospectus or the
         initiation of any proceedings for that purpose, (iii) if, at any time
         when a Prospectus is required by the Securities Act to be delivered in
         connection with sales of the Registrable Securities, the
         representations and warranties of any of the Companies contained in
         any





                                       10
   11
         agreement (including any underwriting agreement) contemplated by
         Section 6(n) below cease to be true and correct in any material
         respect, (iv) of the receipt by any of the Companies of any
         notification with respect to the suspension of the qualification or
         exemption from qualification of a Registration Statement or any of the
         Registrable Securities or the Exchange Securities to be sold by any
         Participating Broker-Dealer for offer or sale in any jurisdiction, or
         the contemplation, initiation or threatening of any proceeding for
         such purpose, (v) of the happening of any event that makes any
         statement made in such Registration Statement or related Prospectus or
         any document incorporated or deemed to be incorporated therein by
         reference untrue in any material respect or that requires the making
         of any changes in such Registration Statement, Prospectus or documents
         so that it will not contain any untrue statement of a material fact or
         omit to state any material fact required to be stated therein or
         necessary to make the statements therein, in light of the
         circumstances under which they were made, not misleading, and (vi) of
         the Company's reasonable determination that a post- effective
         amendment to a Registration Statement would be appropriate.

                 (f)      Use its reasonable efforts to register or qualify,
         and, if applicable, to cooperate with the selling Holders of
         Registrable Securities, the underwriters, if any, and their respective
         counsel in connection with the registration or qualification (or
         exemption from such registration or qualification) of, Securities to
         be included in a Registration Statement for offer and sale under the
         securities or Blue Sky laws of such jurisdictions within the United
         States as any selling Holder, Participating Broker-Dealer or the
         managing underwriters reasonably request in writing; and, if
         Securities are offered other than through an Underwritten Offering,
         the Company shall cause its counsel to perform Blue Sky investigations
         and file registrations and qualifications required to be filed
         pursuant to this Section 6(f) at the expense of the Company; keep each
         such registration or qualification (or exemption therefrom) effective
         during the period such Registration Statement is required to be kept
         effective and do any and all other acts or things necessary or
         advisable to enable the disposition in such jurisdictions of the
         Securities covered by the applicable Registration Statement, provided,
         however, that none of the Companies shall be required to (i) qualify
         generally to do business in  any jurisdiction where it is not then so
         qualified, (ii) to take action that would subject it to general
         service of process in any jurisdiction where it is not so subject or
         (iii) subject it to taxation in excess of a nominal dollar amount in
         any such jurisdiction where it is not then subject.

                 (g)      Use its best efforts to prevent the issuance of any
         order suspending the effectiveness of a Registration Statement or of
         any order preventing or suspending the use of a Prospectus or
         suspending the qualification (or exemption from qualification) of any
         of the Securities for sale in any jurisdiction, and, if any such order
         is issued, to use its best efforts to obtain the withdrawal of any
         such order at the earliest possible time.

                 (h)      If (A) a Shelf Registration is filed pursuant to
         Section 3 or (B) a Prospectus contained in an Exchange Offer
         Registration Statement filed pursuant to Section 2 is required to be
         delivered under the Securities Act by any Participating Broker-Dealer
         who seeks to sell Exchange Securities during the Applicable Period,
         and if requested by the managing underwriters, if any, or the Holders
         of a majority in aggregate principal amount of the Registrable
         Securities, (i) promptly incorporate in a Prospectus or post-effective
         amendment such information as the managing underwriters, if any, or
         such Holders reasonably request to be included therein required to
         comply with any applicable law and (ii) make all required filings of
         such Prospectus or such post-effective amendment as soon as
         practicable after the Company has received notification of





                                       11
   12
         such matters required by Applicable Law to be incorporated in such
         Prospectus or post-effective amendment.

                 (i)      If (A) a Shelf Registration is filed pursuant to

         delivered under the Securities Act by any Participating Broker-Dealer
         who seeks to sell Exchange Securities during the Applicable Period,
         cooperate with the selling Holders and the managing underwriters, if
         any, to facilitate the timely preparation and delivery of certificates
         representing Registrable Securities to be sold, which certificates
         shall not bear any restrictive legends and shall be in a form eligible
         for deposit with The Depository Trust Company ("DTC"); and enable such
         Registrable Securities to be in such denominations and registered in
         such names as the managing underwriters, if any, or Holders may
         reasonably request.

                 (j)      If (i) a Shelf Registration is filed pursuant to
         Section 3 or (ii) a Prospectus contained in an Exchange Offer
         Registration Statement filed pursuant to Section 2 is required to be
         delivered under the Securities Act by any Participating Broker-Dealer
         who seeks to sell Exchange Securities during the Applicable Period,
         upon the occurrence of any event contemplated by paragraph 6(e)(v) or
         6(e)(vi) above, as promptly as practicable prepare a supplement or
         post-effective amendment to the Registration Statement or a supplement
         to the related Prospectus or any document incorporated or deemed to be
         incorporated therein by reference, or file any other required document
         so that, as thereafter delivered to the purchasers of the Registrable
         Securities being sold thereunder or to the purchasers of the Exchange
         Securities to whom such Prospectus will be delivered by a
         Participating Broker-Dealer, such Prospectus will not contain an
         untrue statement of a material fact or omit to state a material fact
         required to be stated therein or necessary to make the statements
         therein, in light of the circumstances under which they were made, not
         misleading.

                 (k)      Use its best efforts to cause the Securities covered
         by a Registration Statement to be rated with the appropriate rating
         agencies, if appropriate, if so requested by the Holders of a majority
         in aggregate principal amount of Securities covered by such
         Registration Statement or the managing underwriters, if any.

                 (l)      Prior to the effective date of the first Registration
         Statement relating to the Securities, (i) provide the applicable
         trustee with printed certificates for the Securities in a form
         eligible for deposit with DTC and (ii) provide a CUSIP number for each

                 (m)      Use its best efforts to cause all Securities covered
         by such Registration Statement to be listed on each securities
         exchange, if any, on which similar debt securities issued by the
         Company are then listed.

                 (n)      If a Shelf Registration is filed pursuant to Section
         3, enter into such agreements (including an underwriting agreement in
         form, scope and substance as is customary in Underwritten Offerings)
         and take all such other actions in connection therewith (including
         those reasonably requested by the managing underwriters, if any, or
         the Holders of a majority in aggregate principal amount of the
         Registrable Securities being sold) in order to expedite or facilitate
         the registration or the disposition of such Registrable Securities,
         and in such connection, regardless of whether an underwriting
         agreement is entered into and regardless of whether the registration
         is an Underwritten Registration, (i) make such representations and
         warranties to the Holders and the underwriters, if any, with respect
         to the business of the Company and its

         documents, if any, incorporated or deemed to be incorporated by
         reference therein, in each case, in form, substance and scope as are
         customarily made by issuers to underwriters in Underwritten Offerings,
         and confirm the same if and when reasonably requested; (ii) obtain
         opinions of counsel to the Company and updates thereof (which counsel
         and opinions (in form, scope and substance) shall be reasonably
         satisfactory to the managing underwriters, if any, and the Holders of
         a majority in aggregate principal amount of the Registrable Securities

         accountants of the Company (and, if necessary, any other independent
         certified public accountants of any subsidiary of the Company or of
         any business acquired by the Company for which financial statements
         and financial data are, or are required to be, included in the

         connection with Underwritten Offerings and such other matters as
         reasonably requested by underwriters; and (iv) deliver such documents
         and certificates as may be reasonably requested by the Holders of a
         majority in principal amount of the Registrable Securities being sold

         validity of the representations and warranties of the Company and its
         subsidiaries made pursuant to clause (i) above and to evidence
         compliance with any conditions contained in the underwriting agreement
         or other similar agreement entered into by the Company.

                 (o)      Comply with all applicable rules and regulations of
         the SEC and make generally available to its security holders earnings
         statements satisfying the provisions of Section 11(a) of the
         Securities Act and Rule 158 thereunder (or any similar rule

         end of any 12-month period (or 90 days after the end of any 12-month
         period if such period is a fiscal year) (i) commencing on the first
         day of the fiscal quarter following each fiscal quarter in which
         Registrable Securities are sold to underwriters in a firm commitment
         or best efforts underwritten offering and (ii) if not sold to
         underwriters in such an offering, commencing on the first day of the
         first fiscal quarter of the Company after the effective date of a
         Registration Statement, which statements shall cover said 12-month
         periods.

                 (p)      Upon consummation of an Exchange Offer or Private
         Exchange, obtain an opinion of counsel to the Company (in form, scope
         and substance reasonably satisfactory to the Purchaser), addressed to
         all Holders participating in the Exchange Offer or Private Exchange,
         as the case may be, to the effect that (i) the Company has duly
         authorized, executed and delivered the Exchange Securities or the
         Private Exchange Securities, as the case may be, and the Indenture,
         (ii) the Exchange Securities or the Private Exchange Securities, as
         the case may be, and the Indenture constitute legal, valid and binding
         obligations of the Company, enforceable against the Company in
         accordance with their respective terms, except as such enforcement may
         be subject to (x) applicable bankruptcy, insolvency, reorganization,
         moratorium and similar laws affecting creditors' rights and remedies
         generally and (y) general principles of equity (regardless of whether
         such enforcement is sought in a proceeding in equity or at law), and
         (iii) all obligations of the Company under the Exchange Securities or
         the Private Exchange Securities, as the case may be, and the Indenture
         are secured by Liens on the assets securing the obligations of the
         Company under the Notes.

   14
                 (q)      If an Exchange Offer or Private Exchange is to be
         consummated, upon delivery of the Registrable Securities by such
         Holders to the Company (or to such other Person as directed by the
         Company) in exchange for the Exchange Securities or the Private
         Exchange Securities, as the case may be, the Company shall mark, or
         caused to be marked, on such Registrable Securities that such
         Registrable Securities are being cancelled in exchange for the
         Exchange Securities or the Private Exchange Securities, as the case
         may be; in no event shall such Registrable Securities be marked as
         paid or otherwise satisfied.

                 (r)      Cooperate with each seller of Registrable Securities
         covered by any Registration Statement and each underwriter, if any,
         participating in the disposition of such Registrable Securities and
         their respective counsel in connection with any filings required to be
         made with the NASD.

                 (s)      Use its best efforts to take all other steps
         reasonably necessary to effect the registration of the Registrable
         Securities covered by a Registration Statement contemplated hereby.

                 The Company may require each seller of Registrable Securities
or Participating Broker-Dealer as to which any registration is being effected
to furnish to the Company such information regarding such seller or
Participating Broker-Dealer and the distribution of such Registrable Securities
or Exchange Securities as the Company may, from time to time, reasonably
request in writing.  The Company may exclude from such registration the
Registrable Securities of any seller or Exchange Securities of any
Participating Broker-Dealer who unreasonably fails to furnish such information.

                 Each Holder and each Participating Broker-Dealer agrees by
acquisition of such Registrable Securities or Exchange Securities of any
Participating Broker-Dealer that, upon receipt of written notice from the
Company of the happening of any event of the kind described in Section
6(e)(ii), 6(e)(iv), 6(e)(v) or 6(e)(vi), such Holder will forthwith discontinue
disposition (in the jurisdictions specified in a notice of a 6(e)(iv) event,
and elsewhere in a notice of a 6(e)(ii), 6(e)(v) or 6(e)(vi) event) of such
Securities covered by such Registration Statement or Prospectus until such
Holder's receipt of the copies of the supplemented or amended Prospectus
contemplated by Section 6(j), or until it is advised in writing (the "Advice")
by the Company that offers or sales in a particular jurisdiction may be resumed
or that the use of the applicable Prospectus may be resumed, as the case may
be, and has received copies of any amendments or supplements thereto.  If the
Company shall give such notice, each of the Effectiveness Period and the
Applicable Period shall be extended by the number of days during such periods
from and including the date of the giving of such notice to and including the
date when each seller of such Securities covered by such Registration Statement
shall have received (x) the copies of the supplemented or amended Prospectus
contemplated by Section 6(j) or (y) the Advice.

         7.      Registration Expenses.

                 (a)      All fees and expenses incident to the performance of
         or compliance with this Agreement by the Companies shall be borne by
         the Company, regardless of whether the Exchange Offer or a Shelf
         Registration is filed or becomes effective, including, without
         limitation:

                          (i)     all registration and filing fees (including,

   15
                 reasonable fees and disbursements of counsel in connection
                 with Blue Sky qualifications of the Registrable Securities or
                 Exchange Securities and determination of the eligibility of
                 the Registrable Securities or Exchange Securities for
                 investment under the laws of such jurisdictions (x) where the
                 Holders are located, in the case of the Exchange Securities,
                 or (y) as provided in Section 6(f), in the case of Registrable
                 Securities or Exchange Securities to be sold by a
                 Participating Broker-Dealer during the Applicable Period);

                          (ii)    printing expenses (including, without
                 limitation, expenses of printing certificates for Registrable
                 Securities or Exchange Securities in a form eligible for
                 deposit with DTC and of printing Prospectuses if the printing
                 of Prospectuses is requested by the managing underwriters, if
                 any, or, in respect of Registrable Securities or Exchange
                 Securities to be sold by a Participating Broker-Dealer during
                 the Applicable Period, by the Holders of a majority in
                 aggregate principal amount of the Registrable Securities
                 included in any Registration Statement or of such Exchange
                 Securities, as the case may be);

                          (iii)   messenger, telephone, duplication, word
                 processing and delivery expenses incurred by the Company in
                 the performance of its obligations hereunder;

                          (iv)    fees and disbursements of counsel for the
                 Company;

                          (v)     fees and disbursements of all independent
                 certified public accountants referred to in Section 6(n)(iii)
                 (including, without limitation, the expenses of any special
                 audit and "cold comfort" letters required by or incident to
                 such performance);

                          (vi)    fees and expenses of any "qualified
                 independent underwriter" or other independent appraiser
                 participating in an offering pursuant to Section 3 of Schedule
                 E to the By-laws of the NASD, but only where the need for such
                 a "qualified independent underwriter" arises due to a
                 relationship with the Company;

                          (vii)   Securities Act liability insurance, if the
                 Company so desires such insurance;

                          (viii)  fees and expenses of all other Persons
                 retained by the Company; internal expenses of the Company
                 (including, without limitation, all salaries and expenses of
                 officers and employees of the Company performing legal or
                 accounting duties); and the expense of any annual audit; and

                          (ix)    rating agency fees and the fees and expenses
                 incurred in connection with the listing of the Securities to
                 be registered on any securities exchange.

                 (b)      The Company shall reimburse the Holders for the
         reasonable fees and disbursements of not more than one counsel (in
         addition to appropriate local counsel) chosen by the Holders of a
         majority in aggregate principal amount of the Registrable Securities
         to be included in any Registration Statement and other reasonable and
         necessary out-of-pocket expenses of the Holders incurred in connection
         with the registration of the Registrable Securities.

         8.      Indemnification.

                 (a)      Indemnification by the Companies.  Each of the
         Companies, jointly and severally, shall, without limitation as to
         time, indemnify and hold harmless each Holder and each Participating
         Broker-Dealer selling Exchange Securities during the Applicable
         Period, each Person who controls each such Holder (within the meaning
         of Section 15 of the Securities Act or Section 20(a) of the Exchange
         Act) and the officers, directors, partners, employees, representatives
         and agents of each such Holder, Participating Broker-Dealer and
         controlling person, to the fullest extent lawful, from and against any
         and all losses, claims, damages, liabilities, costs (including,
         without limitation, reasonable costs of preparation and reasonable
         attorneys' fees) and expenses (including, without limitation,
         reasonable costs and expenses incurred in connection with
         investigating, preparing, pursuing or defending against any of the
         foregoing) (collectively, "Losses"), as incurred, directly or
         indirectly caused by, related to, based upon, arising out of or in
         connection with any untrue or alleged untrue statement of a material
         fact contained in any Registration Statement, Prospectus or form of
         prospectus, or in any amendment or supplement thereto, or in any
         preliminary prospectus, or any omission or alleged omission to state
         therein a material fact required to be stated therein or necessary to
         make the statements therein, in the light of the circumstances under
         which they were made, not misleading, except insofar as such Losses
         are based upon information relating to such Holder or Participating
         Broker-Dealer and furnished in writing to the Company by such Holder
         or Participating Broker-Dealer expressly for use therein; provided,
         however, that none of the Companies shall be liable to any Indemnified
         Party to the extent that any such losses arise solely out of an untrue
         statement or alleged untrue statement or omission or alleged omission
         made in any preliminary prospectus if (i) such Indemnified Party or
         related holder of a Registrable Security failed to send or deliver a
         copy of the Prospectus with or prior to the delivery of written
         confirmation of the sale by such Indemnified Party or the related
         holder of a Registrable Security to the person asserting the claim
         from which such Losses arise, (ii) the Prospectus would have corrected
         such untrue statement or alleged untrue statement or omission or
         alleged omission, and (iii) the Company has complied with its
         obligations under Section 6(e).  Each of the Companies shall also,
         jointly and severally, indemnify underwriters, selling brokers, dealer
         managers and similar securities industry professionals participating
         in the distribution, their officers, directors, agents and employees
         and each Person who controls such Persons (within the meaning of
         Section 15 of the Securities Act or Section 20(a) of the Exchange Act)
         to the same extent as provided above with respect to the
         indemnification of the Holders or the Participating Broker-Dealer.
         Notwithstanding any provision hereof to the contrary, the liability of
         each of TARC and TransTexas pursuant to this Section 8(a) shall be
         limited to the amount of proceeds of the Offering (as defined in the
         Purchase Agreement) received directly or indirectly by such
         corporation, including without limitation pursuant to the transactions
         contemplated hereby, by the Purchase Agreement or by the Offering
         Circular (as defined in the Purchase Agreement).

                 (b)      Indemnification by Holder of Registrable Securities.
         In connection with any Registration Statement, Prospectus or form of
         prospectus, any amendment or supplement thereto, or any preliminary
         prospectus in which a Holder is participating, such Holder shall
         furnish to the Company in writing such information as the Company
         reasonably requests for use in connection with any Registration
         Statement, Prospectus or form of prospectus, any amendment or
         supplement thereto, or any preliminary prospectus and shall, without
         limitation as to time, indemnify and hold harmless the Company, its
         officers, directors, partners, employees, representatives and agents,
         each Person, if any, who controls the Company (within the meaning of
         Section 15 of the Securities Act and Section 20(a) of the Exchange
         Act), and the officers, directors, partners,





                                       16
   17
         employees, representatives and agents of such controlling persons, to
         the fullest extent lawful, from and against all Losses arising out of
         or based upon any untrue or alleged untrue statement of a material
         fact contained in any Registration Statement, Prospectus or form of
         prospectus or in any amendment or supplement thereto or in any
         preliminary prospectus, or any omission or alleged omission to state
         therein a material fact required to be stated therein or necessary to
         make the statements therein, in the light of the circumstances under
         which they were made, not misleading to the extent, but only to the
         extent, that such untrue statement or alleged untrue statement of a
         material fact or omission or alleged omission of a material fact is
         contained in any information so furnished in writing by such holder to
         the Company expressly for use therein.  In no event shall the
         liability of any selling Holder be greater in amount than the dollar
         amount of the proceeds (net of payment of all expenses) received by
         such Holder upon the sale of the Registrable Securities giving rise to
         such indemnification obligation.

                 (c)      Conduct of Indemnification Proceedings.  If any
         Proceeding shall be brought or asserted against any Person entitled to
         indemnity hereunder (an "Indemnified Party"), such Indemnified Party
         shall promptly notify the party or parties from which such indemnity
         is sought (the "Indemnifying Parties") in writing; provided, that the
         failure to so notify the Indemnifying Parties shall not relieve the
         Indemnifying Parties from any obligation or liability except to the
         extent that it shall be finally determined by a court of competent
         jurisdiction (which determination is not subject to appeal) that the
         Indemnifying Parties have been prejudiced materially by such failure.

                          The Indemnifying Party shall have the right,
         exercisable by giving written notice to an Indemnified Party, within
         20 Business Days after receipt of written notice from such Indemnified
         Party of such Proceeding, to assume, at its expense, the defense of
         any such Proceeding, provided, that an Indemnified Party shall have
         the right to employ separate counsel in any such Proceeding and to
         participate in the defense thereof, but the fees and expenses of such
         counsel shall be at the expense of such Indemnified Party or parties
         unless: (1) the Indemnifying Party has agreed to pay such fees and
         expenses; or (2) the Indemnifying Party shall have failed promptly to
         assume the defense of such Proceeding or shall have failed to employ
         counsel reasonably satisfactory to such Indemnified Party; or (3) the
         named parties to any such Proceeding (including any impleaded parties)
         include both such Indemnified Party and the Indemnifying Party or any
         of its affiliates or controlling persons, and such Indemnified Party
         shall have been advised by counsel that there may be one or more
         defenses available to such Indemnified Party that are in addition to,
         or in conflict with, those defenses available to the Indemnifying
         Party or such affiliate or controlling person (in which case, if such
         Indemnified Party notifies the Indemnifying Parties in writing that it
         elects to employ separate counsel at the expense of the Indemnifying
         Parties, the Indemnifying Parties shall not have the right to assume
         the defense thereof and the reasonable fees and expenses of such
         counsel shall be at the expense of the Indemnifying Party; it being
         understood, however, that, the Indemnifying Party shall not, in
         connection with any one such Proceeding or separate but substantially
         similar or related Proceedings in the same jurisdiction, arising out
         of the same general allegations or circumstances, be liable for the
         fees and expenses of more than one separate firm of attorneys
         (together with appropriate local counsel) at any time for such
         Indemnified Parties).

                          No Indemnifying Party shall be liable for any
         settlement of any such Proceeding effected without its written
         consent, but if settled with its written consent, or if there be a
         final judgment for the plaintiff in any such Proceeding, each
         Indemnifying Party jointly and severally agrees, subject to the
         exceptions and limitations set forth above, to indemnify and hold
         harmless





                                       17
   18
         each Indemnified Party from and against any and all Losses by reason
         of such settlement or judgment.  The Indemnifying Party shall not
         consent to the entry of any judgment against an indemnified party or
         enter into any settlement that imposes any obligation on any
         indemnified party that does not include as a term thereof the giving
         by the claimant or plaintiff to each Indemnified Party of a release,
         in form and substance reasonably satisfactory to the Indemnified
         Party, from all liability in respect of such Proceeding for which such
         Indemnified Party would be entitled to indemnification hereunder
         (regardless of whether any Indemnified Party is a party thereto).

                 (d)      Contribution.  If the indemnification provided for in
         this Section 8 is unavailable to an Indemnified Party or is
         insufficient to hold such Indemnified Party harmless for any Losses in
         respect of which this Section 8 would otherwise apply by its terms
         (other than by reason of exceptions provided in this Section 8), then
         each applicable Indemnifying Party, in lieu of indemnifying such
         Indemnified Party, shall have a joint and several obligation to
         contribute to the amount paid or payable by such Indemnified Party as
         a result of such Losses, in such proportion as is appropriate to
         reflect the relative fault of the Indemnifying Party, on the one hand,
         and such Indemnified Party, on the other hand, in connection with the
         actions, statements or omissions that resulted in such Losses as well
         as any other relevant equitable considerations.  The relative fault of
         such Indemnifying Party, on the one hand, and Indemnified Party, on
         the other hand, shall be determined by reference to, among other
         things, whether any untrue or alleged untrue statement of a material
         fact or omission or alleged omission to state a material fact relates
         to information supplied by such Indemnifying Party or Indemnified
         Party, and the parties' relative intent, knowledge, access to
         information and opportunity to correct or prevent any such statement
         or omission.  The amount paid or payable by an Indemnified Party as a
         result of any Losses shall be deemed to include any legal or other
         fees or expenses incurred by such party in connection with any
         Proceeding, to the extent such party would have been indemnified for
         such fees or expenses if the indemnification provided for in Section
         8(a) or 8(b) was available to such party.

                 The parties hereto agree that it would not be just and
         equitable if contribution pursuant to this Section 8(d) were
         determined by pro rata allocation or by any other method of allocation
         that does not take account of the equitable considerations referred to
         in the immediately preceding paragraph. Notwithstanding the provisions
         of this Section 8(d), an Indemnifying Party that is a selling Holder
         shall not be required to contribute, in the aggregate, any amount in
         excess of such Holder's Maximum Contribution Amount.  A selling
         Holder's "Maximum Contribution Amount" shall equal the excess of (i)
         the aggregate proceeds received by such Holder pursuant to the sale of
         such Registrable Securities over (ii) the aggregate amount of damages
         that such Holder has otherwise been required to pay by reason of such
         untrue or alleged untrue statement or omission or alleged omission.
         No person guilty of fraudulent misrepresentation (within the meaning
         of Section 11(f) of the Securities Act) shall be entitled to
         contribution from any Person who was not guilty of such fraudulent
         misrepresentation.

                 The indemnity and contribution agreements contained in this
Section 8 are in addition to any liability that the Indemnifying Parties may
have to the Indemnified Parties.

         9.      Rule 144 and Rule 144A.  Each of the Companies covenants that
it shall (a) file the reports required to be filed by it (if so required) under
the Securities Act and the Exchange Act in a timely manner and, if at any time
any such Person is not required to file such reports, it will, upon the request
of any Holder, make publicly available other information necessary to permit
sales pursuant to





                                       18
   19
Rule 144 and Rule 144A and (b) take such further action as any Holder may
reasonably request, all to the extent required from time to time to enable such
Holder to sell Registrable Securities without registration under the Securities
Act pursuant to the exemptions provided by Rule 144 and Rule 144A.  Upon the
request of any Holder, the Companies shall deliver to such Holder a written
statement as to whether they have complied with such information and
requirements.

         10.     Underwritten Registrations.  If any of the Registrable
Securities covered by any Shelf Registration are to be sold in an Underwritten
Offering, the investment banker or investment bankers and manager or managers
that will manage the offering will be selected by the Holders of a majority in
aggregate principal amount of such Registrable Securities included in such
offering.  No Holder may participate in any Underwritten Registration hereunder
unless such Holder (a) agrees to sell such Holder's Registrable Securities on
the basis provided in any underwriting arrangements approved by the Persons
entitled hereunder to approve such arrangements and (b) completes and executes
all questionnaires, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements.

         11.     Miscellaneous.

                 (a)      Remedies.  In the event of a breach by any of the
         Companies of any of its respective obligations under this Agreement,
         each Holder, in addition to being entitled to exercise all rights
         provided herein, in the Indenture or, in the case of the Purchaser, in
         the Purchase Agreement, or granted by law, including recovery of
         damages, will be entitled to specific performance of its rights under
         this Agreement.  Each of the Companies agrees that monetary damages
         would not be adequate compensation for any loss incurred by reason of
         a breach by it of any of the provisions of this Agreement and hereby
         further agrees that, in the event of any action for specific
         performance in respect of such breach, it shall waive the defense that
         a remedy at law would be adequate.

                 (b)      No Inconsistent Agreements.  The Company has not
         entered into, as of the date hereof, and shall not enter into, after
         the date of this Agreement, any agreement with respect to any of its
         securities that is inconsistent with the rights granted to the holders
         of Registrable Securities in this Agreement or otherwise conflicts
         with the provisions hereof.

                 (c)      Amendments and Waivers.  The provisions of this
         Agreement, including the provisions of this sentence, may not be
         amended, modified or supplemented, and waivers or consents to
         departures from the provisions hereof may not be given, unless the
         Company has obtained the written consent of Holders of at least a
         majority of the then outstanding aggregate principal amount of
         Registrable Securities; provided, that Sections 6(a) and 8 shall not
         be amended, modified or supplemented, and waivers or consents to
         departures from this proviso may not be given, unless the Company has
         obtained the written consent of each Holder affected thereby.
         Notwithstanding the foregoing, a waiver or consent to depart from the
         provisions hereof with respect to a matter that relates exclusively to
         the rights of Holders whose securities are being sold pursuant to a
         Registration Statement and that does not directly or indirectly affect
         the rights of other Holders may be given by Holders of at least a
         majority in aggregate principal amount of the Registrable Securities
         being sold by such Holders pursuant to such Registration Statement,
         provided that the provisions of this sentence may not be amended,
         modified or supplemented except in accordance with the provisions of
         the immediately preceding sentence.
