Item 5.Other Events

     On April 29, 1999, Comstock Resources, Inc. (the "Company") closed the sale
of $150 million in aggregate principal amount of 11.25% Senior Notes due in 2007
(the "Senior  Notes").  Interest on the Senior Notes is payable  semiannually on
May 1 and  November 1,  commencing  on November 1, 1999.  The Senior  Notes were
priced at a discount to yield  11.35% and  proceeds  from the sale of the Senior
Notes were used to reduce  amounts  outstanding  under the Company's bank credit
facility.  The  Senior  Notes  are  unsecured  obligations  of the  Company  and
guaranteed by all of the Company's principal operating subsidiaries. The Company
can redeem the Senior Note beginning on May 1, 2004.

     Concurrently  with the sale of the  Senior  Notes,  the  Company  also sold
1,948,001 shares of its Series A 1999 Convertible Preferred Stock, $10 par value
and 1,051,999  shares of its Series B 1999 Non-Convertible  Preferred Stock, $10
par value (the  "Preferred  Stock"),  in a private  placement for $30 million to
certain  funds and  institutions  for which Trust  Company of the West serves as
investment  manager and to Pacific  Life  Insurance  Company  and Aquila  Energy
Capital Corporation. The proceeds from the private placement were used to reduce
amounts  outstanding  under the Company's  bank credit  facility.  The Preferred
Stock  accrues  dividends  at an annual rate of 9% and are payable  quarterly in
cash or in shares of the Company's common stock, at the election of the Company.
Shares of the Series A 1999 Convertible Preferred Stock are convertible,  at the
option of the holder,  into shares of common stock of the Company.  Based on the
initial  conversion  price of $4.00  per share of common  stock,  each  share of
Series A 1999  Convertible  Preferred  Stock is  convertible  into 2.5 shares of
common stock.  At the Company's  upcoming  annual meeting of  stockholders to be
held on June 23,  1999,  the Company is asking its  stockholders  to approve the
issuance  by the  Company  of  1,051,999  shares  of  Series A 1999  Convertible
Preferred   Stock  upon   conversion  by  the  Company  of  the  Series  B  1999
Non-Convertible  Preferred  Stock  into  shares  of  Series  A 1999  Convertible
Preferred Stock.

     In connection  with the sale of the Senior Notes and the  Preferred  Stock,
the Company entered into a new $162.5 million revolving credit facility with The
First National Bank of Chicago as administrative agent and a syndicate of banks.
As of April 29, 1999, the Company has $104.0 million  outstanding  under the new
bank credit facility.

          cents ($0.225) per share;

                    (b) in  shares  (whether  whole  or  fractional)  of  Freely
          Tradeable  Common Stock valued at the Cash  Equivalent  Amount for the
          purposes of determining the number of shares (or fraction  thereof) of
          Freely Tradeable Common Stock to be issued; or

                    (c) by combination of cash and such shares;


                                       E-5

<PAGE>




provided,  that if any such dividend  shall be paid in a combination of cash and
shares  of Freely  Tradeable  Common  Stock,  all  holders  of the  Series  1999
Preferred Stock shall receive cash and shares of Freely  Tradeable  Common Stock
in the same ratio,  except that the Company, at its option, may pay cash in lieu
of  fractional  shares  of  Freely  Tradeable  Common  Stock  valued at the Cash
Equivalent Amount.

          3.3.  Record Date. The Board of Directors  shall fix a record date for
the  determination  of holders of the Series 1999  Preferred  Stock  entitled to
receive payment of a dividend declared  thereon,  which record date shall be not
more than sixty (60) days prior to the date fixed for the payment thereof.

          3.4.  Restricted  Payments.  Unless full  cumulative  dividends on the
Series 1999  Preferred  Stock have been paid, no dividends  shall be declared or
paid or set apart for payment or other  distribution  upon any Junior  Stock nor
shall any Junior  Stock be  redeemed,  purchased  or  otherwise  acquired by the
Company for any consideration (or any payment made to or available for a sinking
fund for the redemption of any shares of such stock) by the Company.

     4. Redemption.

          4.1. Mandatory Redemption.  On May 1st of each of 2005, 2006 and 2007,
or,  in the event  that any such date is not a  Business  Day,  the  immediately
preceding  Business Day before such date,  the Company  shall redeem a number of
shares (or such lesser  number of shares if a lesser  number of shares  shall be
outstanding  on such  date)  of the  Series  A 1999  Preferred  Stock  equal  to
one-third of (x) the number of Series A 1999 Preferred Stock  originally  issued
by the Company plus (y) the number of Series A 1999 Preferred  Stock issued upon
the  conversion of the Series B 1999  Preferred  Stock and a number of shares of
the Series B 1999  Preferred  Stock equal to one-third of the number of Series B
1999 Preferred Stock originally  issued by the Company (or such lesser number of
shares  if a lesser  number  of  shares  shall  be  outstanding  on such  date);
provided,  that if the  holders  of the  Series  1999  Preferred  Stock  are the
beneficial  owners of at least five percent  (5%) of the issued and  outstanding
Common Stock, the Company shall not be permitted to redeem an aggregate of 1,000
shares of the Series A 1999 Preferred  Stock on May 1, 2007 or thereafter  until
the holders of the Series 1999 Preferred  Stock as of any date of  determination
do not  beneficially own five percent (5%) or more of the issued and outstanding
Common Stock  issued by the Company upon the  conversion  or  redemption  of the
Series 1999  Preferred  Stock or paid by the Company as a dividend on the Series
1999 Preferred Stock, at which time the Company may redeem such shares by paying
the holders of such  shares in cash a price per share  equal to the  Liquidation
Amount. Redemptions pursuant to this Section 4.1 shall be paid, at the option of
the Company,  (i) in cash for a price per share of Series 1999  Preferred  Stock
equal to the Liquidation  Amount, (ii) with shares (whether whole or fractional)
of Freely  Tradeable  Common Stock having a Cash Equivalent  Amount equal to the
Liquidation  Amount or (iii) by combination  of cash and such shares;  provided,
that if such  redemption  shall be paid in a  combination  of cash and shares of
Freely  Tradeable  Common Stock,  all holders of the Series 1999 Preferred Stock
shall  receive  cash and  shares of Freely  Tradeable  Common  Stock in the same
ratio,  except  that  the  Company,  at its  option,  may  pay  cash  in lieu of
fractional shares of Freely Tradeable Common Stock valued at the Cash Equivalent
Amount. In the event that at any time less than all of the shares of Series 1999
Preferred Stock outstanding are to be redeemed pursuant to this Section 4.1, the
Company shall effect such  redemption pro rata according to the number of shares
of Series 1999 Preferred Stock held by each holder thereof.

          4.2.  Redemptions Upon Change of Control or Merger. (a) Upon the sale,
conveyance  or  disposition  of all or  substantially  all of the  assets of the
Company,  a merger,  consolidation or other  reorganization  of the Company in a
transaction   or  series  of  related   transactions   (except   for  a  merger,
consolidation or  reorganization  as to which Subsection 4.2(b) applies or after
the  consummation of which the stockholders of the Company own a majority of the


                                       E-6

<PAGE>


voting securities of the surviving corporation or its parent corporation),  or a
Change of Control, each holder of the Series 1999 Preferred Stock shall have the
right to require that the Company redeem all or any part of such holder's Series
1999  Preferred  Stock on a date that is no  earlier  than three  Business  Days
following the date such holder notifies the Company of its election to cause the
Company  to redeem  its  Series  1999  Preferred  Stock for cash out of  legally
available funds at a price per share equal to the Liquidation Amount.

          (b) Upon a merger or  consolidation  of the  Company  with or into any
other  corporation  or other  entity where (1) either (A) the Company is not the
surviving  corporation  or  (B)  the  Company  shall  issue  to  any  Person  as
consideration  in respect of such  consolidation  or merger any capital stock of
the  Company  representing  twenty  percent  (20%)  or  more  of  the  Company's
outstanding  capital  stock  prior to such  consolidation  or merger and (2) the
Company has not  received  the  affirmative  vote or consent of the holders of a
majority of the outstanding shares of the Series 1999 Preferred Stock, voting as
a separate class,  each holder of the Series 1999 Preferred Stock shall have the
right to require that the Company redeem all or any part of such holder's Series
1999  Preferred  Stock on a date that is no  earlier  than three  Business  Days
following the date such holder notifies the Company of its election to cause the
Company  to redeem  its  Series  1999  Preferred  Stock for cash out of  legally
available funds at a price per share equal to the Applicable IRR Amount.

          (c) If on the date of such sale,  conveyance,  disposition,  Change of
Control,  merger or  consolidation  funds legally  available for such redemption
shall be  insufficient  to redeem all of the  outstanding  shares of Series 1999
Preferred Stock held by holders who have elected to have their shares  redeemed,
funds to the extent  legally  available  shall be used for such  purpose and the
Company shall effect such  redemption pro rata according to the number of shares
of Series 1999  Preferred  Stock held by each  holder  thereof.  The  redemption
requirements provided hereby shall be continuous, so that if on the date of such
sale, conveyance,  disposition,  Change of Control, merger or consolidation such
requirements can not be fully  discharged,  without further action by any holder
of the Series 1999  Preferred  Stock funds  legally  available  shall be applied
therefor until such requirements are fulfilled.

          Prior to the payment in full of the amounts  owing under this  Section
4.2 to any holder of Series  1999  Preferred  Stock who has  elected to have its
shares  redeemed,  the dividends  with respect to such shares shall  continue to
accrue  dividends and such shares shall retain all rights  associated  with such
Series 1999  Preferred  Stock.  Upon payment in full of the amounts  owing under
this Section 4.2 to any holder of Series 1999 Preferred Stock who has elected to
have  its  shares  redeemed,   then  notwithstanding  that  the  certificate  or
certificates  evidencing  such  shares  shall  not have  been  surrendered,  the
dividends  with  respect to such shares  shall cease to accrue after the date of
such payment in full and all rights with respect to such shares shall  forthwith
terminate.

          4.3. Optional Redemption Prior to March 31, 2002. The shares of Series
1999 Preferred Stock may be redeemed, in whole but not in part, at the option of
the Company, at any time prior to March 31, 2002, if the Common Stock has traded
on a recognized  securities  exchange or national market system more than 75,000
shares  per  day  (as  adjusted  for  stock   dividends,   split-ups,   mergers,
recapitalizations,  combinations,  exchanges  of shares  or the  like)  over the
30-trading  day period prior to the date of the  Redemption  Notice  required by
Section 4.5 below at an average  closing  price on such  securities  exchange or
national  market  system  equal to or greater  than the  following  amounts  (as
adjusted   for   stock   dividends,   split-ups,   mergers,   recapitalizations,
combinations, exchanges of shares or the like):

<PAGE>



          On or prior to

           March 31:                          Average Closing Price:

              2000                                   $  6.25

              2001                                   $  8.25

              2002                                   $ 10.00

          Redemptions  pursuant to this Section 4.3 shall be paid, at the option
of the Company, (i) in cash for a price per share of Series 1999 Preferred Stock
equal to the 30-Day Average Price of the Common Stock  immediately prior to such
date of redemption  multiplied by the number of shares of Common Stock  issuable
upon the  conversion  of one share of Series  1999  Preferred  Stock at the then
applicable  Conversion  Price, (ii) with shares (whether whole or fractional) of
Freely  Tradeable  Common Stock valued at a Cash Equivalent  Amount equal to the
cash amount  provided in clause (i) above,  or (iii) with a combination  of cash
and such  shares in amounts  determined  pursuant to clauses (i) and (ii) above,
respectively;  provided,  that if such redemption shall be paid in a combination
of cash and shares of Freely  Tradeable  Common Stock, all holders of the Series
1999 Preferred  Stock shall receive cash and shares of Freely  Tradeable  Common
Stock in the same ratio, except that the Company, at its option, may pay cash in
lieu of fractional  shares of Freely  Tradeable  Common Stock valued at the Cash
Equivalent Amount. Notwithstanding anything set forth in this Section 4.3, there
shall be no trading volume  requirement if redemptions  pursuant to this Section
4.3 are paid in cash as set forth in  clause  (i) of the  immediately  preceding
sentence.  For purposes of calculating  the  redemption  payment of the Series B
1999 Preferred  Stock to be made pursuant to this Section 4.3, the Series B 1999
Preferred Stock shall be deemed to have the same Conversion  Price as the Series
A 1999 Preferred Stock.

          4.4.  Optional  Redemption  After March 31, 2002. The shares of Series
1999 Preferred Stock may be redeemed, in whole but not in part, at the option of
the  Company,  at any time on or after March 31,  2002,  if the Common Stock has
traded on a recognized  securities  exchange or national market system more than
75,000  shares per day (as adjusted  for stock  dividends,  split-ups,  mergers,
recapitalizations,  combinations,  exchanges  of shares  or the  like)  over the
30-trading  day period prior to the date of the  Redemption  Notice  required by
Section 4.5 below.

          Redemptions  pursuant to this Section 4.4 shall be made, at the option
of the Company, (i) in cash for a price per share of Series 1999 Preferred Stock
equal  to the  Applicable  IRR  Amount,  (ii)  with  shares  (whether  whole  or
fractional) of Freely Tradeable Common Stock valued at a Cash Equivalent  Amount
equal to the  Applicable IRR Amount or (iii) with a combination of cash and such
shares  in  amounts   determined   pursuant  to  clauses  (i)  and  (ii)  above,
respectively;  provided,  that if such redemption shall be paid in a combination
of cash and shares of Freely  Tradeable  Common Stock, all holders of the Series
1999 Preferred  Stock shall receive cash and shares of Freely  Tradeable  Common
Stock in the same ratio, except that the Company, at its option, may pay cash in
lieu of fractional  shares of Freely  Tradeable  Common Stock valued at the Cash
Equivalent Amount. Notwithstanding anything set forth in this Section 4.4, there
shall be no trading volume  requirement if redemptions  pursuant to this Section
4.4 are paid in cash as set forth in  clause  (i) of the  immediately  preceding
sentence.

          4.5.  Redemption  Notice.  The Company shall give written  notice (the
"Redemption  Notice") to each holder of the class of Series 1999 Preferred Stock
to be redeemed  by the Company at least 20 Business  Days prior to the date (the
"Redemption  Date") of any  redemption  required or  permitted to be made by the
Company  under this Section 4, such notice to be addressed to each holder at the
address as it appears on the stock  transfer  books of the Company.  Such notice



                                       E-8

<PAGE>


shall  specify  (i) the class or classes of Series  1999  Preferred  Stock to be
redeemed, (ii) the Redemption Date, (iii) the number of all shares of each class
of the Series 1999  Preferred  Stock of each holder to be redeemed  and (iv) the
amount  and form or forms of  payment  therefor  and the  method of  calculation
thereof (the "Redemption  Amount").  On or after each such Redemption Date, each
holder of the Series 1999  Preferred  Stock shall  surrender  a  certificate  or
certificates  representing the number of shares of each class of the Series 1999
Preferred  Stock to be redeemed as stated in the Redemption  Notice  provided by
the Company.  If the Redemption Notice shall have been duly given, and if on the
Redemption  Date  the  Redemption  Amount  is  either  paid or  made  reasonably
available  for  payment  in  immediately  available  funds,  Common  Stock  or a
combination  thereof  as  provided  herein to the  holders  of the  Series  1999
Preferred  Stock being  redeemed,  then  notwithstanding  that the  certificates
evidencing any of the Series 1999 Preferred Stock so called for redemption shall
not have been surrendered, the dividends with respect to such shares shall cease
to accrue after the  Redemption  Date and all rights with respect to such shares
shall forthwith  terminate after the Redemption  Date,  except only the right of
the holders to receive the Redemption  Amount without interest upon surrender of
their  certificate  or  certificates.  Notwithstanding  anything to the contrary
contained  herein,  with  respect to any shares of Series 1999  Preferred  Stock
scheduled for redemption  pursuant to a Redemption  Notice,  the holders of such
shares may at any time prior to the Redemption  Date, upon written notice to the
Company as provided  herein,  exercise their right to convert all or any portion
of such  shares into  Common  Stock at the  Conversion  Price.  For  purposes of
calculating  the redemption  payment of the Series B 1999 Preferred  Stock to be
made  pursuant to this Section 4.5, the Series B 1999  Preferred  Stock shall be
deemed to have the same Conversion Price as the Series A 1999 Preferred Stock.

          4.6.  Series B 1999 Preferred  Stock  Optional  Redemption on or after
December  30, 1999.  At any time and from time to time on or after  December 30,
1999,  each  holder the Series B 1999  Preferred  Stock  shall have the right to
require that the Company  redeem all or any part of such holder's  Series B 1999
Preferred  Stock on a date that is no earlier than three Business Days following
the date such holder  notifies  the Company of its election to cause the Company
to redeem its Series B 1999 Preferred Stock for a redemption  price equal to one
Unit per share of Series B 1999 Preferred Stock.  Each "Unit" shall be comprised
of (x) an amount equal to the Liquidation Amount for such share of Series B 1999
Preferred  Stock (the  "Non-SAR  Amount") and (y) two and  one-half  (2.5) Stock
Appreciation Rights ("SAR's"), in form satisfactory to the holders of the Series
B 1999  Preferred  Stock and their legal counsel,  constituting  the right to be
paid by the Company the difference  between Three Dollars and Seventy Five Cents
($3.75)  per share (the "SAR  Threshold  Amount")  of Common  Stock and the fair
market  value of a share of Common  Stock on the date the SAR is  redeemed  by a
holder of such SAR (the "SAR  Exercise  Amount").  Both the  number of shares of
SAR's and the SAR  Threshold  Amount of the SAR's shall be subject to adjustment
and non-impairment pursuant to anti-dilution  provisions providing substantially
equivalent  protections  as the terms of  Section 8 below in the same  manner as
Series A 1999 Preferred Stock. At any time and from time to time on or after the
grant of the SAR's,  each holder of an SAR shall have the right to require  that
the Company  redeem all or any part of such holder's  SAR's on a date that is no
earlier than three  Business Days  following  the date such holder  notifies the
Company  of its  election  to cause  the  Company  to  redeem  its  SAR's  for a
redemption price equal to the SAR Exercise Amount for such SAR's.

          The Non-SAR Amount shall be paid in (i) cash out of legally  available
funds,  (ii) with  shares  of Freely  Tradeable  Common  Stock  valued at a Cash
Equivalent  Amount equal to the cash amount provided in clause (i) above,  (iii)
with shares of Series A Preferred  Stock valued,  based on the par value of such
shares,  at an  amount  equal to the  Liquidation  Amount  of the  Series B 1999
Preferred Stock redeemed,  or (iv) with a combination of cash and such shares in
amounts determined  pursuant to clause (i), (ii) and (iii) above,  respectively;
provided,  that if the Non-SAR Amount shall be paid in a combination of cash and
shares of Series A 1999 Preferred  Stock and/or Freely  Tradeable  Common Stock,
all holders of the Series B 1999  Preferred  Stock electing to cause the Company
to redeem shares of Series B 1999 Preferred  Stock shall receive cash and shares
of  Series A 1999 Preferred  Stock and/or Freely  Tradeable Common Stock in  the


                                       E-9

<PAGE>



same ratio,  except that the Company, at its option, may (a) pay cash in lieu of
fractional  shares of Series A 1999 Preferred Stock valued at an amount equal to
the cash value of such fraction  shares of Series A 1999 Preferred Stock and (b)
may pay cash in lieu of  fractional  shares of  Freely  Tradeable  Common  Stock
valued at the Cash Equivalent Amount. The Company shall, in its sole discretion,
select from the options set forth in clauses (i) through  (iv) of the  preceding
sentence the form of consideration that the Company shall pay or issue to effect
such redemption;  provided, that if the Company is unable to legally effect such
redemption by one or more of the methods of redemption  set forth in clauses (i)
through  (iv) of the  preceding  sentence,  the Company  must choose a method of
redemption from among the remaining legal methods of redemption.

          The SAR  Exercise  Amount  shall be paid in (i)  cash  out of  legally
available  funds,  (ii) with shares of Freely  Tradeable  Common Stock, or (iii)
with a  combination  of cash and such shares in amounts  determined  pursuant to
clause (i) and (ii)  above,  respectively;  provided,  that if the SAR  Exercise
Amount  shall be paid in a  combination  of cash and shares of Freely  Tradeable
Common  Stock,  all  holders of the SAR's  electing  to cause the Company to pay
SAR's shall receive cash and shares of Freely Tradeable Common Stock in the same
ratio,  except  that  the  Company,  at its  option,  may  pay  cash  in lieu of
fractional shares of Freely Tradeable Common Stock valued at the Cash Equivalent
Amount.  The Company shall, in its sole discretion,  select from the options set
forth in  clauses  (i)  through  (iii)  of the  preceding  sentence  the form of
consideration  that the  Company  shall  pay or issue to  effect  such  payment;
provided, that if the Company is unable to legally effect such payment by one or
more of the methods of payment  set forth in clauses  (i)  through  (iii) of the
preceding  sentence,  the Company must choose a method of payment from among the
remaining legal methods of payment.

          Prior to the payment or issuance  in full of the  consideration  owing
under this  Section 4.6 to any holder of Series B 1999  Preferred  Stock who has
elected to have its shares  redeemed,  the dividends with respect to such shares
shall  continue  to accrue  dividends  and such shares  shall  retain all rights
associated with such Series B 1999 Preferred Stock.  Upon payment or issuance in
full of the consideration owing under this Section 4.6 to any holder of Series B
1999  Preferred  Stock  who  has  elected  to have  its  shares  redeemed,  then
notwithstanding  that the  certificate or  certificates  evidencing  such shares
shall not have been surrendered, the dividends with respect to such shares shall
cease to  accrue  after the date of such  payment  in full and all  rights  with
respect to such shares shall forthwith terminate.

     5. Liquidation Rights.  Upon any liquidation,  dissolution or winding up of
the affairs of the Company,  no distribution shall be made to the holders of any
Junior Stock unless,  prior to the first such  distribution,  the holders of the
Series 1999 Preferred Stock shall have received the Liquidation  Amount.  If the
assets  distributable  in any  such  event to the  holders  of the  Series  1999
Preferred  Stock are  insufficient  to permit the payment to such holders of the
full  preferential  amounts to which they may be entitled,  such assets shall be
distributed  ratably  among the  holders of the Series 1999  Preferred  Stock in
proportion to the full  preferential  amount each such holder would otherwise be
entitled to receive.

     6. Voting Rights of Series 1999 Preferred Stock.

          6.1 Voting Rights.  The holders of the Series A 1999  Preferred  Stock
shall be entitled,  on all matters submitted for a vote of the holders of shares
of Common Stock, whether pursuant to law or otherwise,  to a number of votes per
share of the  Series A 1999  Preferred  Stock  equal to the  number of shares of
Common  Stock  issuable  upon  conversion  of one  share  of the  Series  A 1999
Preferred  Stock on the date of such vote,  and on all such  matters  shall vote
together  as one class with the  holders of Common  Stock and the holders of all
other shares of stock  entitled to vote with the holders of Common Stock on such
matters.

          6.2 Special Voting Rights. In addition, the holders of the Series 1999
Preferred  Stock shall have the voting powers provided for by law and shall have
the further  voting powers  provided for below.  If one or more of the Events of


                                      E-10

<PAGE>


Noncompliance  (defined  below) occurs and remains  outstanding and has not been
specifically waived in writing by holders of eighty percent (80%) or more of the
shares of the Series 1999 Preferred Stock,  then, to the extent permitted by law
as relating to  directorships,  the holders of such Series 1999 Preferred  Stock
shall have the right,  voting as single class  separately from all other classes
and series, to elect two directors of the Company, the remaining directors to be
elected  by the other  classes  or series of stock  entitled  to vote  therefor,
including  the  Series  1999  Preferred  Stock as set forth in Section  6.1.  In
addition,  the Series  1999  Preferred  Stock  shall have the right to elect two
directors  each  time that the  Company  mandatorily  redeems  the  Series  1999
Preferred  Stock by issuing  Freely  Tradeable  Common  Stock to the  holders of
Series 1999  Preferred  Stock  pursuant  to the terms of Section 4.1 above.  The
maximum number of directors that the holders of Series 1999 Preferred  Stock may
elect  pursuant to this Section 6.2 shall be four. If and when such right of the
holders of the Series  1999  Preferred  Stock  becomes  operative,  the  maximum
authorized  number of members of the Board of  Directors  of the  Company  shall
automatically  be  increased  to the extent  necessary  to create any vacancy or
vacancies to be filled only by vote of the holders of the Series 1999  Preferred
Stock then  outstanding  as  hereinafter  set forth.  Whenever such right of the
holders of the Series 1999 Preferred  Stock shall become  operative,  such right
shall be exercised  initially  either at a special meeting of the holders of the
Series 1999  Preferred  Stock  called as provided in Section 6.3 below or at any
annual meeting of stockholders held for the purpose of electing  directors,  and
thereafter at such annual  meetings.  In electing the directors to be elected by
the holders of the Series 1999 Preferred Stock,  each holder of such stock shall
have one vote for each  share  thereof  held.  The right of the  holders  of the
Series 1999 Preferred Stock,  voting as a single class separately from all other
classes  and  series,  to elect two  members  of the Board of  Directors  of the
Company  as a  result  of the  occurrence  of an Event  of  Noncompliance  shall
continue  until such event is cured or waived as set forth above,  at which time
the right of the holders of the Series 1999 Preferred  Stock to vote  separately
and as a single class as provided in this Section 6.2 shall  terminate  (subject
to becoming operative again in the event of a subsequent Event of Noncompliance)
and the maximum  authorized  number of members of the Board of  Directors of the
Company shall  automatically be reduced if such number was increased at the time
when the  terminated  voting  right of the holders of the Series 1999  Preferred
Stock became  operative.  Notwithstanding  the foregoing,  in no event shall the
Company increase the number of members of the Board of Directors above six, plus
those  members of the Board of  Directors  elected by the  holders of the Series
1999  Preferred  Stock.  In the event that (i) the  holders  of the Series  1999
Preferred Stock elect members of the Board of Directors of the Company  pursuant
to this Section 6.2,  and (ii) all of the Series 1999  Preferred  Stock has been
converted or redeemed, so long as the holders of the Series 1999 Preferred Stock
are the beneficial  owners of the percentage of Common Stock listed below,  such
holders of the Series 1999  Preferred  Stock  shall  continue to have the right,
voting as a single class  separately from all other classes or series,  to elect
the number members of the Board of Directors of the Company listed below:

                  Percentage Ownership  No. of Members of
                       Common Stock        Board of Directors

                           20% or more               4

                           15 - 19.99%               3

                           10 - 14.99%               2

                             5 - 9.99%               1

                           Less than 5%              0;

provided,  that in  calculating  the  percentage  of Common  Stock  owned by the
holders,  only Common  Stock (x) issued by the Company  upon the  conversion  or



                                      E-11

redemption  of the Series 1999  Preferred  Stock or (y) paid by the Company as a
dividend  on  the  Series  1999  Preferred  Stock  shall  be  included  in  such
calculation.  If the  holder(s) of the Series 1999  Preferred  Stock elect fewer
directors  than  allowed by this Section  6.2,  the  director(s)  elected by the
holder(s) of the Series 1999 Preferred Stock shall  nonetheless  have the number
of votes  equal to the  number of  directors  the  holders  of the  Series  1999
Preferred Stock could have elected  pursuant to this Section 6.2, so that at any
subsequent  meeting of the Board of  Directors  of the  Company,  each  director
elected by the  holder(s) of the Series 1999  Preferred  Stock  pursuant to this
Section 6.2 shall have the number of votes equal to the number of directors that
the holder(s) of the Series 1999 Preferred Stock could have elected  pursuant to
this Section 6.2 (the "Available  Director  Seats") divided by the actual number
of  directors  elected by the  holder(s)  of the  Series  1999  Preferred  Stock
pursuant to this Section 6.2 and attending such meeting (the "Actual Directors")
and, for purposes of  determining  whether a quorum is present at such  meeting,
each such director that was elected by the holders of the Series 1999  Preferred
Stock and is present at such  meeting  shall be counted as a number of directors
equal to the number of the  Available  Director  Seats  divided by the number of
Actual Directors.

          Such  "Events of  Noncompliance",  in  addition  to those set forth in
Section 7, are:

                    (a) the  failure by the  Company to pay,  in the  aggregate,
          four  quarterly  dividends  or  the  equivalent  on  the  Series  1999
          Preferred  Stock on the  dates on which  the same  should  be  payable
          according to the terms hereof whether or not  consecutive  and whether
          or not such  dividends have been declared and whether or not there are
          any  monies of the  Company  properly  applicable  to the  payment  of
          dividends;

                    (b) the  failure by the  Company  to redeem the Series  1999
          Preferred Stock when such redemption is required hereunder;

                    (c) the  occurrence  of any event or condition in respect of
          any debts or security of the  Company or any of its  subsidiaries,  or
          under any agreement securing or relating to such debt or security, the
          effect of which is to cause or to permit  any  holder of such debts or
          other  security  or trustee to cause  (whether  or not such  holder or
          trustee elects to cause) such debts or security, or a portion thereof,
          to become due prior to its stated  maturity or prior to its  regularly
          scheduled  dates of payment  provided that,  with respect to any debts
          other than the Company's  senior bank or other credit  facility,  such
          debts in the aggregate exceed Ten Million Dollars ($10,000,000);

                    (d) a  breach  by the  Company  of  any  covenant,  term  or
          condition  hereof,  or in  respect  of any  debts or  security  of the
          Company  or any of  its  subsidiaries,  or  any  under  any  agreement
          securing  or  relating  to such  debts or  security,  which  breach is
          continuing and uncured for a period of at least 30 days after delivery
          of written notice thereof to the Company;  provided that, with respect
          to any debts  other than the  Company's  senior  bank or other  credit
          facility,  such  debts in the  aggregate  exceed Ten  Million  Dollars
          ($10,000,000);

          Allison  in  the  operations  and  affairs  of  the  Company  and  its
          subsidiaries  as Mr.  Allison is involved on the Closing Date,  unless
          Mr.  Allison  has been  replaced  in such  capacities  by a person  or
          persons  approved  in writing by the  holders of a majority or more of
          the Series 1999 Preferred Stock, in their sole discretion;

                    (f)  the  commencement  of  an  involuntary  case  or  other
          proceeding  against the Company or any of its subsidiaries which seeks
          liquidation,  reorganization or other relief with respect to it or its

          it or any substantial  part of its property,  or the entry of an order
          for relief against the Company or any of its  subsidiaries in any such
          case under the United States Bankruptcy Code;

                    (g)  the   commencement   by  the  Company  or  any  of  its
          subsidiaries  of  a  voluntary  case  or  other  proceeding,   seeking
          liquidation,  reorganization or other relief with respect to itself or
          its debts or other  liabilities  under any  bankruptcy,  insolvency or
          other   similar  law  now  or  hereafter  in  effect  or  seeking  the
          appointment  of a trustee,  receiver,  liquidator,  custodian or other
          similar  official of it or any  substantial  part of its property,  or

          possession  by any  such  official  in an  involuntary  case or  other
          proceeding  commenced  against it, or the making by the Company or any
          of its  subsidiaries  of a  general  assignment  for  the  benefit  of

          otherwise  being  satisfied  in  accordance  with its terms and is not
          stayed on appeal or otherwise  being  appropriately  contested in good
          faith and if reserves  adequate under  generally  accepted  accounting
          principles shall not have been established therefor.

                    6.3. Procedures Relating to Special Voting Rights.

                    (a) At any  time  when  the  special  voting  rights  of the
          holders of the Series  1999  Preferred  Stock  provided in Section 6.2
          above  shall have  become  operative  and not have been  exercised,  a
          proper officer of the Company shall,  upon the written  request of the
          holders of record of at least  twenty  percent  (20%) of the shares of
          Series  1999  Preferred  Stock  then  outstanding   addressed  to  the
          Secretary of the Company, call a special meeting of the holders of the
          Series  1999  Preferred  Stock for the  purpose  of  electing  the two
          directors  to be elected  by the Series  1999  Preferred  Stock.  Such
          meeting shall be held at the earliest practicable date upon the notice
          required  for annual  meetings  of  stockholders  at such place in the
          continental United States as may be specified in such written request.
          If such  meeting  shall  not be called by the  proper  officer  of the
          Company  within  twenty (20) days after the  personal  service of such
          written  request upon the  Secretary of the Company,  or within twenty
          (20)  days  after  mailing  the  same  within  the  United  States  by
          registered or certified mail enclosed in a postpaid envelope addressed
          to the  Secretary  of the Company at its  principal  office,  then the
          holders of record of at least  twenty  percent  (20%) of the shares of
          Series A 1999  Preferred  Stock  then  outstanding  may  designate  in
          writing one of their number to call such meeting at the expense of the
          Company,  and such  meeting may be called by the person so  designated
          upon the notice required for annual meetings of stockholders and shall
          be held at such  place  in the  continental  United  States  as may be
          specified  in such  notice.  Notwithstanding  the  provisions  of this
          Section 6.3, no such special meeting shall be called during the period
          of sixty (60) days immediately preceding the date fixed for any annual
          or special  meeting  of  stockholders  if the staff of the  Commission
          shall have  advised the Company  that the calling of any such  meeting
          shall require the Company to amend or supplement its proxy  soliciting
          materials  relating to such annual or special meeting of stockholders;
          and no such special meeting shall be called if in connection with such
          meeting a proxy  solicitation  conforming to the rules and regulations
          issued under the Securities Exchange Act of 1934, as amended, shall be
          required,  but in such event the  election of directors by the holders



                                      E-13

<PAGE>


          of the Series 1999 Preferred Stock shall take place at the next annual
          meeting of stockholders, unless the right of the holders of the Series
          1999  Preferred  Stock to elect  directors  shall in the meantime have
          terminated.

                    (b) Upon any  termination of the right of the holders of the
          Series 1999 Preferred Stock to elect directors as hereinabove provided
          (including  as  holders  of Common  Stock),  the term of office of any
          director  then in office  elected by the Series 1999  Preferred  Stock
          shall terminate immediately.  If the office of any director elected by
          the  holders of the Series  1999  Preferred  Stock  becomes  vacant by
          reason of death, resignation,  retirement,  disqualification,  removal
          from office or otherwise,  then the procedure  provided for in Section
          6.3(a) above shall be used to fill the vacancy.

                    (c) Subject to the  provisions of Section 6.2, the Bylaws of
          the Company shall automatically be deemed amended from time to time to
          provide for the increase or reduction in the maximum authorized number
          of members of the Board of Directors and for the election procedure as
          hereinabove in this Section 6.3 provided.

          6.4. Rights Relating to Board of Directors.  The Company will promptly
execute  and  deliver  to any  individual  elected  to the  Board of  Directors,
pursuant to Section  6.2, an  agreement  by the  Company to  indemnify  and hold
harmless such individual for any and all actions taken by such individual in his
capacity as a member of the Board of Directors to the fullest  extent  permitted
by the laws of the  state of  incorporation  of the  Company.  Unless  waived or
modified by the holders of a majority of the Series 1999 Preferred  Stock voting
as a single  class,  the  Company  will also use its best  efforts  to  promptly
provide for such individual such amount of director's  liability insurance as is
normal and customary for  corporations  which have common stock that is publicly
traded on the New York Stock Exchange or the NASDAQ National  Market System.  In
addition  to the rights of the  holders of the Series  1999  Preferred  Stock to
elect  directors  as  provided  herein,  any  holder  of  more  than  15% of the
outstanding  Series 1999  Preferred  Stock which does not have a  representative
acting as a member of the Board of Directors  shall have the right to appoint an
observer who may attend and  participate  in all meetings  (including  committee
meetings)  of the  Board of  Directors  and who  shall be  entitled  to the same
expense reimbursement as Directors of the Company.

          6.5.  Certain  Actions  by the  Company.  So long as any shares of the
Series 1999 Preferred Stock are  outstanding,  the Company will not, without the
affirmative  vote or consent of all of the holders of the outstanding  shares of
Series 1999 Preferred Stock,  voting as a separate classes,  amend or repeal any
provision of, or add any provision to, the Company's  Articles of  Incorporation
which affect the dividend  rate,  Liquidation  Amount,  liquidation  preference,
conversion  price,  put right,  dividend  and  liquidation  priority,  mandatory
redemption rights and terms of or any material rights or privileges  relating to
the Series 1999 Preferred Stock.

          Unless  the vote or  consent  of the  holders  of a greater  number of
shares shall then be required by law or as provided in the immediately preceding
paragraph,  and so long as any shares of the  Series  1999  Preferred  Stock are
outstanding,  the Company will not,  without the affirmative  vote or consent of
the holders of at least eighty percent (80%) of the outstanding shares of Series
1999 Preferred Stock, voting as separate classes:

                    (a) amend or repeal any  provision  of, or add any provision
          to, the  Company's  Articles of  Incorporation  which affect the other
          rights,  powers,  preferences  or terms of the Series  1999  Preferred
          Stock;

                    (b) merge or consolidate  with or into any other Person,  or
          sell, assign, convey,  transfer,  lease or otherwise dispose of all or
          substantially  all of the properties and assets of the Company and its
          subsidiaries  on a  consolidated  basis  to any  Person  or  group  of
          affiliated Persons,


                                      E-14

<PAGE>



          or permit any of its  subsidiaries to enter into any such  transaction
          or series of related  transactions  if such  transaction  or series of
          transactions,  in the aggregate, would result in the sale, assignment,
          conveyance,   transfer,   lease  or  other   disposition   of  all  or
          substantially  all of the properties and assets of the Company and its
          subsidiaries  on a consolidated  basis to any other Person or group of
          affiliated  Persons,  unless (I) at the time and after  giving  effect
          thereto either (A) if the  transaction  is a merger or  consolidation,
          the  Company  shall  be  the  surviving   Person  of  such  merger  or
          consolidation, or (B) the Person (if other than the Company) formed by
          such consolidation or into which the Company is merged or to which the
          properties and assets of the Company or its subsidiaries,  as the case
          may be, are sold, assigned, conveyed, transferred, leased or otherwise
          disposed of (any such surviving Person or transferee  Person being the
          "Surviving  Entity")  shall be a  corporation  organized  and existing
          under the laws of the United  States of America,  any state thereof or
          the District of Columbia and shall,  in either case,  issue  preferred
          stock of the  Surviving  Entity into which the Series  1999  Preferred
          Stock is converted or for which it is  exchanged  having  preferences,
          conversion and other rights,  privileges voting powers,  restrictions,
          limitations  as  to   distributions,   qualifications   and  terms  or
          conditions or redemption thereof identical to those of the Series 1999
          Preferred Stock; (II) immediately  before and immediately after giving
          effect to such transaction or series of related  transactions on a pro
          forma  basis  (and  treating  any   indebtedness   not  previously  an
          obligation of the Company or any of its subsidiaries  which becomes an
          obligation  of the Company or any of its  subsidiaries  in  connection
          with or as a result of such  transactions  having been incurred at the
          time of such  transaction),  no default or event of default shall have
          occurred  and be  continuing  under  any  funded  indebtedness  of the
          Company  or the  Surviving  Entity;  (III)  except  in the case of the
          consolidation  or merger of any  subsidiary  with or into the Company,
          immediately after giving effect to such transaction or transactions on
          a pro forma  basis,  the  consolidated  net worth  (as  determined  in
          accordance  with GAAP) of the Company (or the Surviving  Entity if the
          Company  is  not  the  surviving  entity)  is at  least  equal  to the
          consolidated  net  worth  of  the  Company   immediately  before  such
          transaction  or   transactions;   (IV)  except  in  the  case  of  the
          consolidation  or merger of the Company with or into a  subsidiary  or
          any  subsidiary  with or  into  the  Company  or  another  subsidiary,
          immediately  before  and  immediately  after  giving  effect  to  such
          transaction or  transactions  on a pro forma basis  (assuming that the
          transaction or transactions occurred on the first day of the period of
          four fiscal quarters ending  immediately  prior to the consummation of
          such  transaction or  transactions,  with the appropriate  adjustments
          with respect to the transaction or transactions being included in such
          pro forma  calculation),  the Company (or the Surviving  Entity if the
          Company is not the  surviving  entity) could incur $1.00 of additional
          indebtedness (other than specifically permitted indebtedness) pursuant
          to the  provisions of the senior debt  facilities of the Company;  and
          (V) the  Company  (or the  Surviving  Entity if the Company is not the
          surviving  entity)  shall have  delivered to the holders of the Series
          1999 Preferred,  in form and substance reasonably  satisfactory to the
          holders of a majority of the outstanding  Series 1999 Preferred Stock,
          (a) an officers' certificate stating that such consolidation,  merger,
          transfer, lease or other disposition and any supplemental indenture in
          respect thereto comply with the  requirements  under this  Certificate
          and (b) an opinion of counsel stating that the  requirements of clause
          (I) of this paragraph have been satisfied;

                    (c) sell or convey all or substantially all of the assets of
          the Company, or dissolve or liquidate the Company;

                    (d)  reclassify  any  Common  Stock into  shares  having any
          preference  or  priority  as  to  the  payment  of  dividends  or  the
          distribution  of  assets  superior  to or on a  parity  with  any such
          preference or priority of the Series 1999 Preferred Stock; or

                    (e) declare or pay any dividend,  or make any  distribution,
          or purchase,  redeem or otherwise  acquire for value any capital stock


                                      E-15

          or other interest in the Company now or hereafter outstanding, or make
          any other  distribution  of its  assets,  to the holders of any Junior
          Stock, unless (i) no Event of Noncompliance shall have occurred and be
          continuing immediately prior to and after such distributions, (ii) all
          accumulated  dividends with respect to the Series 1999 Preferred Stock
          have  been paid in full  immediately  prior to such  distribution  and
          (iii) the aggregate  amount of all such  distributions in any 12-month
          period does not exceed One Hundred Thousand Dollars ($100,000).

     7. Covenants of the Company.  The failure by the Company to comply with any
of the  covenants  set forth  below,  unless  specifically  waived in writing by
holders of a majority or more of the Series 1999  Preferred  Stock,  shall be an
Event of  Noncompliance.  Except as specifically set forth in Section 7.1 below,
the  holders of the Series  1999  Preferred  Stock  shall have no  remedies  for
violation of the  covenants set forth below other than (i) election of directors
as provided in Section  6.2 and (ii) a right to  specific  performance  or other
equitable  remedies.  7.1.  Board  of  Directors.  So  long as the  Series  1999
Preferred  Stock shall remain  outstanding,  the Company  shall not increase the
number  of  directors  above  six,  except in  connection  with the right of the
holders of the Series A 1999 Preferred  Stock to elect  directors as provided in
Section 6.2 above.

          7.8. Common Stock Reserved;  Legality.  The Company shall at all times
reserve and keep available out of its authorized but unissued  Common Stock such
number of shares of Common  Stock as shall  from time to time be  sufficient  to
effect the conversion of all  outstanding  shares of the Series A 1999 Preferred
Stock;  all of such shares of the Common Stock which are issuable to the holders
of the Series 1999 Preferred Stock by way of conversion,  redemption or dividend
will,  when  issued,  be duly  authorized  and  validly  issued,  fully paid and
nonassessable, and free from all taxes, liens and charges.

     8. Conversion of Series A 1999 Preferred Stock. The Series A 1999 Preferred
Stock shall be convertible as follows:

          8.1. Right to Convert. Each share of the Series A 1999 Preferred Stock
shall be convertible, without the payment of any additional consideration by the
holder  thereof and at the option of the holder  thereof,  at any time after the
date of  issuance of such  share,  at the office of the Company or any  transfer
agent for the Series A 1999 Preferred Stock, into the whole number of fully paid
and nonassessable  shares of Common Stock determined by dividing the Liquidation
Amount by the  Conversion  Price in effect at the time of  conversion,  plus, in
lieu of any fractional  share to which such holder would  otherwise be entitled,
cash equal to such fraction multiplied by the Conversion Price.

          8.2. Mechanics of Conversion.  In order for any holder of the Series A
1999  Preferred  Stock to convert the same into Common Stock,  such holder shall
deliver  a written  notice to the  Company  that he elects to  convert  all or a
specified  number of such  shares and  stating  therein  his name or the name or
names of his nominees in which he wishes the  certificate  or  certificates  for
Common  Stock to be issued  (the  "Conversion  Notice").  The holder  shall also
surrender to the Company at the office of the Company or of any  transfer  agent
for  the  Series  A  1999  Preferred  Stock,  the  certificate  or  certificates
representing  the Series A 1999  Preferred  Stock to be  converted.  The Company
shall,  as soon as practicable  thereafter,  issue and deliver at such office to
such holder of the Series A 1999 Preferred Stock, or to his nominee or nominees,
a certificate or certificates  representing the number of shares of Common Stock
to which he shall be entitled as aforesaid  and, if less than the full number of
shares  of the  Series A 1999  Preferred  Stock  evidenced  by such  surrendered
certificate  or  certificates  are  being   converted,   a  new  certificate  or
certificates,  of like  tenor,  for the  number of  shares of the  Series A 1999
Preferred Stock  evidenced by such  surrendered  certificate  less the number of
such shares being converted.  Any conversion made at the election of a holder of
the Series A 1999 Preferred Stock shall be deemed to have been made  immediately
prior to the  close of  business  on the date  the  Conversion  Notice  has been
received  by the  Company,  and the Person or Persons  entitled  to receive  the
Common Stock issuable upon  conversion  shall be treated for all purposes as the
record holder or holders of such Common Stock on such date.

          8.3. Adjustments to Conversion Price for Diluting Issues:

                    (a) Stock Dividends,  Subdivisions and Combinations. In case
          at any time or from time to time the Company shall:

                              (1)  take  a  record   of  the   holders   of  its
                    Nonpreferred  Stock for the  purpose  of  entitling  them to
                    receive a dividend  payable  in, or other  distribution  of,
                    Nonpreferred Stock;

                              (2)   subdivide   its   outstanding    shares   of
                    Nonpreferred  Stock  into  a  larger  number  of  shares  of
                    Nonpreferred Stock; or

                              (3) combine its outstanding shares of Nonpreferred
                    Stock into a smaller number of shares of Nonpreferred Stock;


                                      E-18

<PAGE>



          then the Conversion Price in effect immediately after the happening of
          any such  event  shall be  proportionately  decreased,  in case of the
          happening of events  described in  subparagraphs  (1) or (2) above, or
          proportionately   increased,  in  case  of  the  happening  of  events
          described in subparagraph (3) above.

                    (b) Certain Other  Dividends and  Distributions.  In case at
          any time or from time to time the  Company  shall take a record of the
          holders of its Nonpreferred Stock for the purpose of entitling them to
          receive any dividend or other distribution of:

                              (1) cash (other than a cash distribution made as a
                    dividend  and  payable  out of  earnings  or earned  surplus
                    legally  available  for the payment of  dividends  under the
                    laws of the jurisdiction of incorporation of the Company, to
                    the extent,  but only to the extent,  that the  aggregate of
                    all such  dividends  paid or declared after the date hereof,
                    does  not  exceed  the  consolidated  net  income,   net  of
                    consolidated net losses, of the Company and its consolidated
                    subsidiaries earned subsequent to the date hereof determined
                    in   accordance   with   generally    accepted    accounting
                    principles);

                              (2) any evidence of its  indebtedness  (other than
                    Convertible Securities), any shares of its stock (other than
                    Additional  Shares  of  Nonpreferred  Stock)  or  any  other
                    securities or property of any nature  whatsoever (other than
                    cash and other than  Convertible  Securities  or  Additional
                    Shares of Nonpreferred Stock); or

                              (3) any warrants or other rights to subscribe  for
                    or purchase any  evidences of its  indebtedness  (other than
                    Convertible Securities), any shares of its stock (other than
                    Additional  Shares  of  Nonpreferred  Stock)  or  any  other
                    securities or property of any nature  whatsoever (other than
                    cash and other than  Convertible  Securities  or  Additional
                    Shares of Nonpreferred Stock);

          then the  Conversion  Price in effect shall be adjusted to that number
          determined by  multiplying  the  Conversion  Price then in effect by a
          fraction (x) the numerator of which shall be the Fair Market Price per
          share of Common  Stock  immediately  prior to the date of taking  such
          record  minus the portion  applicable  to one share of Common Stock of
          any such cash so  distributable  and of the fair  value of any and all
          such evidences of indebtedness,  shares of stock,  other securities or
          property,  or warrants or other  subscription or purchase  rights,  so
          distributable  and (y) the  denominator  of  which  shall  be the Fair
          Market Price per share of Common Stock  immediately  prior to the date
          of taking such record. Such fair value shall be determined pursuant to
          the Valuation Procedure.  The "Valuation Procedure" is a determination
          of fair  value of any  property  made in good  faith  by the  Board of
          Directors; provided, that if the holders of a majority of the Series A
          1999 Preferred  Stock object to such  determination  within 10 days of
          receipt of written notification  thereof,  then the fair value of such
          property  shall be determined  in good faith by a recognized  national
          investment  bank selected by unanimous vote or consent of the Board of
          Directors,  which investment bank is not reasonably objected to by the
          holders of a majority of the Series A 1999 Preferred  Stock.  The fees
          and expenses of such investment  bank shall be paid by the Company.  A
          reclassification of the Nonpreferred Stock into shares of Nonpreferred
          Stock  and  shares  of any  other  class  of stock  shall be  deemed a
          distribution by the Company to the holders of its  Nonpreferred  Stock
          of such shares of such other class of stock within the meaning of this
          Section 8.3(b) and, if the outstanding  shares of  Nonpreferred  Stock
          shall  be  changed  into a larger  or  smaller  number  of  shares  of
          Nonpreferred Stock as a part of such reclassification, shall be deemed
          a subdivision or  combination,  as the case may be, of the outstanding
          shares of Nonpreferred Stock within the meaning of Section 8.3(a).

                    (c) Issuance of Additional Shares of Nonpreferred  Stock. In
          case at any time or from time to time  after  the  Closing  Date,  the
          Company  shall  (except as  hereinafter  provided)  issue,  whether in
          connection  with the  merger  of a  corporation  into the  Company  or
          otherwise,   any  Additional  Shares  of  Nonpreferred   Stock  for  a
          consideration  per share less than either the Conversion  Price or the
          Fair Market  Price per share of Common Stock on the  Computation  Date
          (determined as set forth in the last sentence of this Section 8.3(c)),
          then the Conversion Price shall be adjusted to the lower of either:

                              (i) that  number  determined  by  multiplying  the
                    Conversion  Price  in  effect   immediately  prior  to  such
                    adjustment by a fraction (x) the numerator of which shall be
                    the number of shares of Nonpreferred  Stock, plus the number
                    of  shares  of   Nonpreferred   Stock  which  the  aggregate
                    consideration for the total number of such Additional Shares
                    of  Nonpreferred  Stock so issued would purchase at the Fair
                    Market   Price  per  share  of  Common  Stock  and  (y)  the
                    denominator  of  which  shall be the  number  of  shares  of
                    Nonpreferred Stock plus the number of such Additional Shares
                    of Nonpreferred Stock so issued; or

                              (ii) the value of the  consideration per share for
                    which  such  Additional  Shares of  Nonpreferred  Stock were
                    issued (or, in the case of adjustments under Sections 8.3(d)
                    or 8.3(e), are issuable).

          No adjustment of the Conversion Price shall be made under this Section
          8.3(c) upon the  issuance  of any  Additional  Shares of  Nonpreferred
          Stock  which are issued  pursuant to the  exercise of any  warrants or
          other  subscription  or purchase rights or pursuant to the exercise of
          any conversion or exchange  rights in any Convertible  Securities,  if
          any such adjustment  shall previously have been made upon the issuance
          of such  warrants  or  other  rights  or  upon  the  issuance  of such
          Convertible  Securities  (or upon the issuance of any warrant or other
          rights therefor) pursuant to Section 8.3(d) or 8.3(e). For purposes of
          this Section 8.3(c),  the Computation Date shall be the earlier of (i)
          the date on which the Company shall enter into a firm contract for the
          issuance of such Additional Shares of Nonpreferred  Stock, or (ii) the
          date of actual  issuance  of such  Additional  Shares of  Nonpreferred
          Stock.

                    (d) Issuance of Warrants,  Options or Other Rights.  In case
          at any time or from time to time after the Closing  Date,  the Company
          shall take a record of the holders of its  Nonpreferred  Stock for the
          purpose  of  entitling  them to  receive a  distribution  of, or shall
          otherwise  issue,  any warrants,  options or other rights to subscribe
          for or purchase any  Additional  Shares of  Nonpreferred  Stock or any
          Convertible  Securities  and the  consideration  per  share  for which
          Additional Shares of Nonpreferred  Stock may at any time thereafter be
          issuable  pursuant  to such  warrants,  options  or  other  rights  or
          pursuant  to the terms of such  Convertible  Securities  shall be less
          than either the Conversion Price or the Fair Market Price per share of
          Common Stock on the Computation  Date  (determined as set forth in the
          last sentence of this Section 8.3(d)), then the Conversion Price shall
          be adjusted as provided in Section 8.3(c).  Such  adjustment  shall be
          made on the basis that (i) the maximum number of Additional  Shares of
          Nonpreferred Stock issuable pursuant to all such warrants,  options or
          other rights or necessary to effect the  conversion or exchange of all
          such Convertible  Securities shall be deemed to have been issued as of
          the Computation  Date (determined as set forth in the last sentence of
          this Section 8.3(d)),  and (ii) the aggregate  consideration  for such
          maximum  number of Additional  Shares of  Nonpreferred  Stock shall be
          deemed to be the minimum consideration  received and receivable by the
          Company for the  issuance of such  Additional  Shares of  Nonpreferred
          Stock pursuant to such  warrants,  options or other rights or pursuant
          to the terms of such  Convertible  Securities.  For  purposes  of this
          Section 8.3(d), the Computation Date shall be the earliest to occur of
          (a) the date on which the  Company  shall take a record of the holders


                                      E-20

<PAGE>



          of its Nonpreferred Stock for the purpose of entitling them to receive
          any such warrants,  options or other rights, (b) the date on which the
          Company  shall  enter into a firm  contract  for the  issuance of such
          warrants, options or other rights, and (c) the date of actual issuance
          of such warrants, options or other rights.

                    (e) Issuance of Convertible Securities.  In case at any time
          or from time to time after the Closing Date,  the Company shall take a
          record of the  holders of its  Nonpreferred  Stock for the  purpose of
          entitling them to receive a distribution of, or shall otherwise issue,
          any Convertible  Securities and the  consideration per share for which
          Additional Shares of Nonpreferred  Stock may at any time thereafter be
          issuable pursuant to the terms of such Convertible Securities shall be
          less than either the  Conversion  Price or the Fair  Market  Price per
          share of Common Stock on the Computation Date (determined as set forth
          in the last  sentence of this  Section  8.3(e)),  then the  Conversion
          Price  shall  be  adjusted  as  provided  in  Section   8.3(c).   Such
          adjustments  shall be made on the basis that (i) the maximum number of
          Additional  Shares of  Nonpreferred  Stock  necessary  to  effect  the
          conversion  or exchange of all such  Convertible  Securities  shall be
          deemed to have been issued as of the Computation  Date  (determined as
          set forth in the  penultimate  sentence of this Section  8.3(e)),  and
          (ii) the aggregate consideration for such maximum number of Additional
          Shares  of  Nonpreferred  Stock  shall  be  deemed  to be the  minimum
          consideration  received and receivable by the Company for the issuance
          of such Additional Shares of Nonpreferred  Stock pursuant to the terms
          of such Convertible Securities.  No adjustment of the Conversion Price
          shall be made under  this  Section  8.3(e)  upon the  issuance  of any
          Convertible  Securities  which are issued  pursuant to the exercise of
          any warrants or other subscription or purchase rights therefor, if any
          such adjustment  shall  previously have been made upon the issuance of
          such warrants or other rights pursuant to Section 8.3(d). For purposes
          of this Subsection,  the Computation Date shall be the earliest of (a)
          the date on which the  Company  shall take a record of the  holders of
          its  Nonpreferred  Stock for the purpose of entitling  them to receive
          any such  Convertible  Securities,  (b) the date on which the  Company
          shall enter into a firm contract for the issuance of such  Convertible
          Securities,  and (c) the date of actual  issuance of such  Convertible
          Securities.

                    (f) Superseding  Adjustment of Conversion  Price. If, at any
          time after any adjustment of the Conversion Price shall have been made
          pursuant to the foregoing Section 8.3(d) or 8.3(e) on the basis of the
          issuance  of  warrants  or  other  rights  or the  issuance  of  other
          Convertible Securities,  or after any new adjustment of the Conversion
          Price shall have been made pursuant to this Section 8.3(f):

                              (1) all of such warrants, options or rights or the
                    right of  conversion  or exchange in such other  Convertible
                    Securities shall expire, and none of such warrants,  options
                    or rights, or the right of conversion or exchange in respect
                    of such other  Convertible  Securities,  as the case may be,
                    shall have been exercised; or

                              (2)  the   consideration   per  share,  for  which
                    Additional   Shares  of  Nonpreferred   Stock  are  issuable
                    pursuant to all of such  warrants,  options or rights or the
                    terms of all of such other Convertible Securities,  shall be
                    increased solely by virtue of provisions  therein  contained
                    for an automatic  increase in such  consideration  per share
                    upon the arrival of a specified  date or the  happening of a
                    specified  event,  and  none of such  warrants,  options  or
                    rights, or the right of conversion or exchange in respect of
                    such other Convertible Securities, as the case may be, shall
                    have been exercised;

          such  previous  adjustment  shall be  rescinded  and  annulled and the
          Additional Shares of Nonpreferred Stock which were deemed to have been
          issued  by  virtue  of the  computation  made in  connection  with the
          adjustment so rescinded and annulled shall no longer be deemed to have



                                      E-21

<PAGE>


          been issued by virtue of such computation.  Thereupon, a recomputation
          shall be made of the  effect of such  warrants,  rights or  options or
          other  Convertible  Securities  on the  basis  of  treating  any  such
          warrants,  options or rights or any such other Convertible  Securities
          which  then  remain  outstanding  as  having  been  granted  or issued
          immediately  after the time of such increase of the  consideration per
          share for such Additional  Shares of  Nonpreferred  Stock are issuable
          under such warrants or rights or other Convertible Securities; and, if
          and to the  extent  called  for by the  foregoing  provisions  of this
          Section 8.3 on the basis aforesaid, a new adjustment of the Conversion
          Price shall be made, which new adjustment shall supersede the previous
          adjustment so rescinded and annulled.

                    (g) Other  Provisions  Applicable to Adjustments  Under this
          Section. The following provisions shall be applicable to the making of
          adjustments of the Conversion Price hereinbefore  provided for in this
          Section 8.3:

                              (1) Treasury Stock. The sale or other  disposition
                    of any issued shares of Nonpreferred  Stock owned or held by
                    or for  the  account  of the  Company  shall  be  deemed  an
                    issuance thereof for purposes of this Section 8.3.

                              (2)  Computation of  Consideration.  To the extent
                    that any  Additional  Shares  of  Nonpreferred  Stock or any
                    Convertible  Securities  or any  warrants,  options or other
                    rights to subscribe for or purchase any Additional Shares of
                    Nonpreferred  Stock or any Convertible  Securities  shall be
                    issued  solely  for cash  consideration,  the  consideration
                    received by the Company  therefor  shall be deemed to be the
                    amount of cash received by the Company therefor, or, if such
                    Additional  Shares  of  Nonpreferred  Stock  or  Convertible
                    Securities are offered by the Company for subscription,  the
                    subscription   price,  or,  if  such  Additional  Shares  of
                    Nonpreferred  Stock or  Convertible  Securities  are sold to
                    underwriters  or  dealers  for  public  offering  without  a
                    subscription offering, the initial public offering price, in
                    any such case  excluding any amounts paid or receivable  for
                    accrued interest or accrued  dividends and without deduction
                    of any compensation,  discounts or expenses paid or incurred
                    by the Company for and in the  underwriting of, or otherwise
                    in connection with, the issue thereof. The consideration for
                    any  Additional   Shares  of  Nonpreferred   Stock  issuable
                    pursuant  to  any  warrants,  options  or  other  rights  to
                    subscribe   for  or   purchase   the   same   shall  be  the
                    consideration  received  or  receivable  by the  Company for
                    issuing  such  warrant,  options or other  rights,  plus the
                    additional  consideration  payable to the  Company  upon the
                    exercise  of such  warrants,  options or other  rights.  The
                    consideration  for any  Additional  Shares  of  Nonpreferred
                    Stock  issuable  pursuant  to the  terms of any  Convertible
                    Securities shall be the consideration received or receivable
                    by the Company for issuing any  warrants or other  rights to
                    subscribe for or purchase such Convertible Securities,  plus
                    the consideration  paid or payable to the Company in respect
                    of the  subscription  for or  purchase  of such  Convertible
                    Securities,  plus  the  additional  consideration,  if  any,
                    payable to the  Company  upon the  exercise  of the right of
                    conversion or exchange in such  Convertible  Securities.  To
                    the extent that any  issuance  shall be for a  consideration
                    other than solely for cash, then, except as herein otherwise
                    expressly  provided,  the amount of such consideration shall
                    be deemed to be the fair value of such  consideration at the
                    time  of  such  issuance  as  determined   pursuant  to  the
                    Valuation Procedure.

                              (3) When  Adjustments to be Made. The  adjustments
                    required by the  preceding  subsections  of this Section 8.3
                    shall be made whenever and as often as any  specified  event
                    requiring  an  adjustment   shall  occur,   except  that  no
                    adjustment of the Conversion  Price that would  otherwise be
                    required  shall be made (except in the case of a subdivision
                    or  combination  of  shares  of the  Nonpreferred  Stock  as
                    provided  for in  Section  8.3(a))  unless  and  until  such
                    adjustment, either by  itself or with  other adjustments not


                                      E-22

<PAGE>



                    previously  made,  adds or  subtracts  at least  five  cents
                    ($0.05) to the Conversion Price, as determined in good faith
                    by the Board of  Directors of the  Company.  Any  adjustment
                    representing a change of less than such minimum amount shall
                    be  carried  forward  and  made as soon as such  adjustment,
                    together with other adjustments required by this Section 8.3
                    and  not  previously   made,   would  result  in  a  minimum
                    adjustment. For the purpose of any adjustment, any specified
                    event  shall be  deemed  to have  occurred  at the  close of
                    business on the date of its occurrence.

                              (4) Fractional Interests. In computing adjustments
                    under this Section 8.3, fractional interests in Nonpreferred
                    Stock   shall  be  taken  into   account   to  the   nearest
                    one-thousandth of a share.

                              (5) When  Adjustment Not Required.  If the Company
                    shall take a record of the holders of its Nonpreferred Stock
                    for the purpose of  entitling  them to receive a dividend or
                    distribution  or  subscription or purchase rights and shall,
                    thereafter   and   before   the   distribution   thereof  to
                    shareholders,  legally  abandon  its plan to pay or  deliver
                    such  dividend,   distribution,   subscription  or  purchase
                    rights,  then thereafter no adjustment  shall be required by
                    reason of the taking of such record and any such  adjustment
                    previously  made in respect  thereof  shall be rescinded and
                    annulled.

                    (h) Merger,  Consolidation or Disposition of Assets. In case
          the Company shall merge or consolidate  into another  corporation,  or
          shall sell,  transfer or otherwise dispose of all or substantially all
          of its  property,  assets  or  business  to  another  corporation  and
          pursuant to the terms of such merger,  consolidation  or  disposition,
          shares of common stock of the successor or acquiring  corporation  are
          to be received by or distributed to the holders of Nonpreferred  Stock
          of the  Company,  then  each  holder  of a share of the  Series A 1999
          Preferred  Stock  shall have the right  thereafter  to  receive,  upon
          exercise of such share of the Series A 1999 Preferred Stock, shares of
          common stock each  comprising  the number of shares of common stock of
          the successor or acquiring corporation  receivable upon or as a result
          of such merger,  consolidation or disposition of assets by a holder of
          the  number  of shares of  Common  Stock  into  which one share of the
          Series A 1999 Preferred Stock could be converted  immediately prior to
          such event. If, pursuant to the terms of such merger, consolidation or
          disposition of assets,  any cash,  shares of stock or other securities
          or  property  of any nature  whatsoever  (including  warrants or other
          subscription or purchase  rights) are to be received by or distributed
          to the  holders of  Nonpreferred  Stock of the  Company in addition to
          common  stock of the  successor  or  acquiring  corporation,  then the
          Conversion Price in effect shall be adjusted to that number determined
          by multiplying  the Conversion  Price then in effect by a fraction (x)
          the  numerator  of which shall be the Fair  Market  Price per share of
          Common  Stock  immediately  prior  to  the  closing  of  such  merger,
          consolidation or disposition minus the portion applicable to one share
          of  Common  Stock of any such  cash so  distributable  and of the fair
          value of any such shares of stock or other  securities  or property so
          received or distributed  and (y) the denominator of which shall be the
          Fair Market Price per share of Common Stock  immediately  prior to the
          closing of such merger,  consolidation or disposition.  The fair value
          of any such shares of stock or other  securities or property  shall be
          determined  pursuant to the Valuation  Procedure.  In case of any such
          merger,   consolidation  or  disposition  of  assets,   the  successor
          acquiring  corporation  shall  expressly  assume the due and  punctual
          observance  and  performance  of each and every covenant and condition
          hereof to be  performed  and  observed  by the  Company and all of the
          obligations and liabilities hereunder, subject to such modification as
          shall be necessary to provide for adjustments to the Conversion  Price
          which shall be as nearly  equivalent as practicable to the adjustments
          provided  for in this  Section.  For  the  purposes  of this  Section,
          "common stock of the successor or acquiring corporation" shall include


                                      E-23

<PAGE>


          stock of such  corporation of any class,  which is not preferred as to
          dividends or assets over any other class of stock of such  corporation
          and which is not  subject to  redemption,  and shall also  include any
          evidences of  indebtedness,  shares of stock or other securities which
          are  convertible  into or  exchangeable  for any  such  stock,  either
          immediately  or upon the arrival of a specified  date or the happening
          of a specified  event,  and any  warrants or other rights to subscribe
          for or  purchase  any such stock.  The  foregoing  provisions  of this
          Section   8.3(h)  shall   similarly   apply  to  successive   mergers,
          consolidations or dispositions of assets.

                    (i) Other Action  Affecting  Nonpreferred  Stock. In case at
          any  time or from  time to time the  Company  shall  take  any  action
          affecting its  Nonpreferred  Stock,  other than an action described in
          any of the foregoing  Sections  8.3(a) through (h),  inclusive,  then,
          unless in the opinion of the Board of  Directors  such action will not
          have a materially adverse effect upon the rights of the holders of the
          Series A 1999 Preferred  Stock, the Conversion Price shall be adjusted
          in such manner and at such time as the Board of Directors  may in good
          faith determine to be equitable in the circumstances.

          8.4. No Impairment. Other than in connection with the amendment of its
Articles of Incorporation approved by the requisite number of stockholders,  the
Company will not, through any reorganization, transfer of assets, consolidation,
merger, dissolution,  issue or sale of securities or any other voluntary action,
avoid  the  observance  or  performance  of any of the terms to be  observed  or
performed hereunder by the Company but will at all times in good faith assist in
the  carrying out of all the  provisions  of this Section 8 and in the taking of
all such  action as may be  necessary  or  appropriate  in order to protect  the
conversion  rights of the holders of the Series A 1999  Preferred  Stock against
impairment.  Without  limiting the generality of the foregoing,  the Company (i)
will not permit the par value of any shares of stock at the time receivable upon
the  conversion of the Series A 1999  Preferred  Stock to exceed the  Conversion
Price  then in effect,  (ii) will take all such  action as may be  necessary  or
appropriate  in order that the Company may validly and legally  issue fully paid
nonassessable  shares of stock on the  conversion of the Series A 1999 Preferred
Stock, and (iii) will not issue any Additional  Shares of Nonpreferred  Stock or
Convertible Securities or take any action which results in any adjustment of the
Conversion  Price if the total number of shares of Common Stock  issuable  after
such issuance or action upon the  conversion or redemption of, or payment of all
outstanding  dividends on, all of the then  outstanding  shares of Series A 1999
Preferred  Stock  will  exceed the total  number of shares of Common  Stock then
authorized  by the  Company's  Articles of  Incorporation  and available for the
purpose of issue upon such conversion or redemption or payment of such dividend.

          8.5.  Certificate  as to  Adjustments.  Upon  the  occurrence  of each
adjustment or readjustment  of the Conversion  Price pursuant to this Section 8,
the  Company  at  its  expense  shall  promptly   compute  such   adjustment  or
readjustment  in accordance  with the terms hereof and furnish to each holder of
the Series A 1999 Preferred Stock a certificate setting forth such adjustment or
readjustment  and  showing in detail the facts  upon  which such  adjustment  or
readjustment is based,  including a statement of (i) the consideration  received
or to be received by the Company for any Additional Shares of Nonpreferred Stock
issued  or sold or  deemed to have  been  issued,  (ii) the  number of shares of
Nonpreferred  Stock  outstanding  or  deemed  to be  outstanding,  and (iii) the
Conversion  Price  in  effect  immediately  prior  to such  issue or sale and as
adjusted and readjusted on account thereof,  showing how it was calculated.  The
Company shall,  upon the written request at any time of any holder of the Series
A 1999  Preferred  Stock  furnish or cause to be furnished to such holder a like
certificate  setting  forth  (i) the  Conversion  Price at the  time in  effect,
showing how it was calculated, and (ii) the number of shares of Common Stock and
the amount,  if any, of other  property which at the time would be received upon
the conversion of the Series A 1999 Preferred Stock.

          8.6. Notices of Record Date. In the event of any taking by the Company
of a record  of the  holders  of any  class of  securities  for the  purpose  of


                                      E-24

<PAGE>


determining  the  holders  thereof who are  entitled to receive any  dividend or
other distribution, or any right to subscribe for, purchase or otherwise acquire
any  shares of stock of any class or any other  securities  or  property,  or to
receive any other right,  the Company  shall mail to each holder of the Series A
1999 Preferred  Stock at least ten days prior to the date specified  therein,  a
notice  specifying  the date on which  any such  record  is to be taken  for the
purpose of such dividend or distribution.

          8.7 Conversion  Option. The Company will have the option, at any time,
to convert the Series A 1999 Preferred  Stock,  on the same terms and conditions
set forth herein, to convertible subordinated debt of the Company, provided that
all of the  following  conditions  are  satisfied:  (i) the  Company  shall have
delivered  to  the  holders  thereof  all  necessary  approvals,   subordination
agreements and other  documentation,  in form and substance  satisfactory to the
holders  of the  Series  A 1999  Preferred  Stock in  their  sole  and  absolute
discretion,  required in connection with such conversion (which will provide for
an  increase in the number of demand  registrations,  the  reasonable  costs and
expenses of which shall be payable by the Company, to a number acceptable to the
holders  of the  Series  A 1999  Preferred  Stock in  their  sole  and  absolute
discretion)  and (ii) the  holders  thereof  shall have  received  an opinion of
counsel to the Company (a) that such  conversion  neither  breaches nor violates
any existing  agreement to which the Company is a party or any other  obligation
of the  Company,  (b) such  conversion  shall  not  cause an  adjustment  in the
conversion  price,  option price or exercise price in any  convertible  security
issued by the Company, and (c) such other matters as the holders of the Series A
1999 Preferred Stock may request.

     9. Conversion of Series B 1999 Preferred Stock. The Series B 1999 Preferred
Stock  shall  be  convertible  as follows:

          9.1 Mandatory  Conversion.  The Series B 1999 Preferred Stock shall be
converted,  in whole but not in part,  into Series A 1999  Preferred  Stock upon
resolution of the Board of Directors of the Company on a share-for-share  basis,
as such number of shares of Series A 1999 Preferred Stock may be  proportionally
increased or decreased  upon the occurrence of an event set forth in Section 8.3
above;  provided,  that all  accumulated,  unpaid dividends on the Series B 1999
Preferred Stock are paid  concurrently  with the conversion of the Series B 1999
Preferred Stock into Series A 1999 Preferred Stock.

          9.2 Mechanics of  Conversion.  In order for the Company to convert the
Series B 1999 Preferred  Stock into Series A 1999 Preferred  Stock,  the Company
shall deliver a written notice to all of the holders of Series B Preferred Stock

                       FIFTH AMENDMENT TO RIGHTS AGREEMENT


     This Fifth  Amendment is entered into and is effective as of April 29, 1999
by and between  Comstock  Resources,  Inc. (the  "Company")  and American  Stock
Transfer & Trust Company,  as successor Rights Agent (the "Rights Agent"),  with
respect to that certain  Rights  Agreement  dated as of December  10,  1990,  as
amended,  a copy of  which is  attached  hereto  as  Exhibit  "A"  (the  "Rights
Agreement").

                                     RIGHTS

     A. The  Company  intends to issue and sell to certain  investors  (together
with their successors,  the "1999 Preferred  Holders") an aggregate of 3,000,000
shares of its Series A 1999  Convertible  Preferred  Stock and an  aggregate  of
1,051,999  shares of its  Series B 1999  Non-Convertible  Preferred  Stock  (the
Series A 1999 Convertible  Preferred Stock and the Series B 1999 Non-Convertible
Preferred  Stock are  collectively  referred to  hereafter  as the "Series  1999
Preferred  Stock") pursuant to the terms of a Stock Purchase  Agreement dated as
of April 29, 1999 between the Company,  Trust  Company of the West and TCW Asset
Management  Company in the capacities set forth therein,  Pacific Life Insurance
Company and Aquila Energy Capital Corporation (the "Stock Purchase  Agreement").
Capitalized  terms  used  herein but not  otherwise  defined  herein  shall have
meaning  ascribed  thereto  in the  Rights  Agreement  as in  effect on the date
hereof.

     B. Pursuant to the Certificate of Designation for the Series 1999 Preferred
Stock, the Company may also issue in connection with a redemption of some of the
Series 1999 Preferred Stock certain Stock Appreciation Rights ("SAR's").

     C. As a condition to their  purchase of the shares of Series 1999 Preferred
Stock,  the 1999  Preferred  Holders have required that the Rights  Agreement be
amended to exclude,  under certain conditions,  the Series 1999 Preferred Stock,
the Common Stock issued by way of conversion or redemption of, or payment of any
dividend on the Series 1999 Preferred  Stock or in satisfaction of amounts owing
under the SAR's  (collectively,  the  "Conversion  Shares"),  the 1999 Preferred
Holders  and  certain  other  Persons  from  certain  provisions  of the  Rights
Agreement.

     D. The  Company  has  determined  that the offer and sale of the  shares of
Series 1999  Preferred  Stock are in the best interest of the Company and all of
its stockholders, and is therefore willing to so amend the Rights Agreement.

                                    AGREEMENT

     NOW, THEREFORE, pursuant to Section 27 of the Rights Agreement, the Company

                    (b) any Affiliate, fund participant,  trust beneficiary,  or

          ("Tamco"),  listed in the  definition  of "TCW" in the Stock  Purchase
          Agreement  or any fund,  foundation,  trust or other  Person for whose
          benefit  any such  agreement  with  Trustco  or Tamco  relates  or any
          trustee, custodian or nominee of or for any such Person; and

                    (d) any  Person  (including  any  "group"  as defined in the

          or  Conversion  Shares  then held by any of the Persons  described  in

          given the Company the right of first  offer  described  in Section 1.2
          below).

whether  the  holder of such  shares is an  "Acquiring  Person"  or an  "Adverse
Person" for any purpose under the Rights Agreement.

          1.2 No  transferee  of any shares of Series  1999  Preferred  Stock or
Conversion  Shares shall be entitled to the  exclusions set forth in Section 1.1

transferor of such shares shall have  delivered a written  notice to the Company
offering to sell such shares to the Company or its designee for cash at the same
price and on the same terms as offered to the proposed  transferee  and (ii) the
Company or its designee  shall have failed to accept such offer within seven (7)
business  days of the  Company's  receipt  thereof  and to close  such  sale and
purchase on the scheduled closing date set forth in the terms offered.

     2. Miscellaneous

          2.1 Subject to the terms set forth herein,  the Rights Agreement shall
remain in full force and effect.

one and the same instrument.

warranties  of each Holder in Section  2.3, the Company has not  registered  the

Dividend  Shares  or the  Conversion  Shares  will be sold or  offered  for sale
without  registration  under  said  Act  or  the  availability  of an  exemption
therefrom  or if said  Act is not  applicable,  all as more  fully  provided  in
Section 4, nor in violation of any other law of the United  States of America or
any state.

          2.5.  Expenses.  Whether or not the  Preferred  Shares are sold to any
Holder,  the Company will pay all costs and expenses incurred by the Holders (a)

issuance of the Preferred  Shares  (including,  without  limitation,  reasonable
fees, office charges and expenses of Milbank, Tweed, Hadley & McCloy, counsel to
certain of the Holders and  $25,000 to TCW for its other  out-of-pocket  costs),
(b) provided for in Sections 4.7, 4.8, 5.1 and 5.2, (c) relating to printing the
instruments  evidencing the Preferred Shares or the Common Shares,  (d) expenses
relating to any  amendments,  waivers or consents  under this  Agreement and (e)
incident to the  enforcement by any Holder of, or the protection or preservation

Incorporation or any other agreement  furnished pursuant hereto or thereto or in

the following conditions are satisfied:  (i) the Company shall have delivered to
the  Holders  all  necessary  approvals,   subordination  agreements  and  other
documentation,  in form and substance  satisfactory  to Purchasers in their sole

costs  and  expenses  of which  shall be  payable  by the  Company,  to a number
acceptable  to Purchasers  in their sole and absolute  discretion)  and (ii) the
Holders  shall have  received an opinion of counsel to the Company (a) that such
conversion  neither  breaches nor  violates any existing  agreement to which the
Company is a party or any other  obligation of the Company,  (b) such conversion
shall not cause an adjustment in the conversion price,  option price or exercise
price in any  convertible  security  issued by the  Company,  and (c) such other

Preferred  Shares to be issued pursuant to this Agreement,  and (ii) options and
warrants to purchase an  aggregate  of  5,111,030  shares of Common Stock as set
forth on Schedule 3.1.1 hereto.

          3.1.2.  The Preferred  Shares will,  when issued,  be duly and validly
issued, fully paid and nonassessable and free from all taxes, liens and charges.

          3.1.3. The Company will at all times reserve and keep available out of
its  authorized but unissued  shares of Common Stock,  solely for the purpose of
the  conversion  of the Series A Preferred  Shares,  such  number of  Conversion
Shares  issuable  upon the  conversion  of all  outstanding  Series A  Preferred
Shares.  All Conversion  Shares,  Series B Conversion Shares and Dividend Shares
will, when issued, be duly and validly issued,  fully paid and nonassessable and
free from all taxes,  liens and charges.  The Company will take all such actions
as may be necessary to assure that all  Conversion  Shares,  Series B Conversion
Shares and Dividend Shares may be so issued without  violation of any applicable
law or governmental  regulation or any  requirements of any domestic  securities
exchange or national market upon which the Conversion Shares and Dividend Shares
may be listed.

          3.1.4.  None of the execution and delivery of this  Agreement,  or the
issue and sale of the Preferred  Shares,  the Conversion Shares and the Dividend
Shares, or the consummation of the transactions  herein or therein  contemplated
or  compliance  with the terms and  provisions  hereof and thereof will conflict
with or result in a breach of, or require any  consent  under,  the  Articles of
Incorporation of the Company, or any applicable law or regulation, or any order,
writ,  injunction  or decree of any court or  governmental  authority  or agency
(other than filings  which will be made by the Company as required by applicable
state securities laws), or any agreement or instrument to which the Company is a
party or by which it is bound or to which it is subject, or constitute a default
under any such agreement or instrument,  or result in the creation or imposition
of any lien upon any of the  revenues or assets of the  Company  pursuant to the
terms of any such agreement or instrument.

          3.1.5.  There is not in effect on the date hereof any agreement by the
Company (other than this Agreement)  pursuant to which any holders of securities
of the Company  have a right to cause the Company to  register  such  securities
under the Securities Act other than as set forth on Schedule 3.1.5 hereto.

          3.1.6.  The  Company  is a  corporation  duly  organized  and  validly
existing  in good  standing  under the laws of the  State of Nevada  and has the
corporate  power and  authority  to execute  and  deliver  this  Agreement,  the
Preferred  Shares,  the Conversion Shares and the Dividend Shares and to perform
the terms  hereof and  thereof.  The Company has taken all action  necessary  to
authorize  the  execution,  delivery  and  performance  of this  Agreement,  the
issuance of the Preferred Shares, the Conversion Shares and the Dividend Shares.
This Agreement has been duly  authorized and executed and constitutes the legal,


                                      E-34

valid and binding obligations of the Company, enforceable against the Company in
accordance  with its terms,  except as enforcement may be limited by bankruptcy,
insolvency,  reorganization,  moratorium or similar laws or equitable principles
relating to or limiting creditors' rights generally.

          3.1.7. As a condition to the obligations of the Holders  hereunder and
prior to the issuance of the Preferred  Shares  subscribed  for by Purchasers on
behalf of the parties to this Agreement  listed on Schedule A, the Company shall
have delivered to the Holders (in form and substance satisfactory to Holders and

          matters  contemplated  by this  Agreement,  (B)  attaching  a true and
          complete  copy of the  Articles  of  Incorporation  and by-laws of the

          3.2. Governmental  Consent.  Other than filings required by applicable
state securities laws which shall be made by the Company,  neither the nature of
the Company or of any its subsidiaries, or of any of their respective businesses
or properties,  nor any  relationship  between the Company or any subsidiary and
any other Person,  nor (except as expressly  provided for in this Agreement) any
circumstance  in  connection  with the  offer,  issue  or sale of the  Preferred
Shares,  the  Conversion  Shares and the  Dividend  Shares is such as to require
consent, approval or authorization of, or filing,  registration or qualification
with,  any  governmental  authority on the part of the Company as a condition to
the execution and delivery of this  Agreement or the execution and filing of the
Certificate  of  Designation  or any amendment of the Articles of  Incorporation
required in connection with the  authorization,  offer,  sale and/or issuance of
the Preferred Shares, the Conversion Shares or the Dividend Shares.

          3.3. Private Offering. Neither the Company nor any other Person acting
on behalf of the Company has offered any of the Preferred  Shares or any similar
securities  of the Company for sale to, or  solicited  offers to buy any thereof
from,  or otherwise  approached  or  negotiated  with  respect  thereto with any
prospective purchasers who are not accredited investors,  as defined in Rule 501
of Regulation D promulgated  under the  Securities  Act. The Company agrees that
neither the  Company  nor anyone  acting on its behalf has offered or will offer
the Preferred Shares or any part thereof or any similar  securities for issue or
sale to, or has  solicited  or will solicit any offer to acquire any of the same
from, anyone so as to bring the issuance and sale of the Preferred Shares within
the  provisions  of  Section  5 of the  Securities  Act.  Based  in  part on the
representations of the Holders set forth herein, the offer, sale and issuance of
the Preferred  Shares in conformity  with the terms of this Agreement are exempt
from the  registration  requirements  of the  Securities  Act and any applicable
state securities laws.

adverse to the Company,  would have a material  adverse effect on the Company or
on any of its  subsidiaries  or the  ability of the  Company to  consummate  the
transactions contemplated hereby.

          3.5.  No  Material  Misstatements.  No  representation,  warranty,  or
statement  by  Company  in  this  Agreement  or  in  any  written  statement  or
certificate  furnished  or to be  furnished  to the  Holders  pursuant  to  this
Agreement  contains  any  untrue  statement  of a material  fact or,  when taken
together,  omits a material fact necessary to make the statements made herein or
therein not misleading.

          3.6.  Ownership of  Subsidiaries.  The Company has good and marketable
title to all the outstanding stock of each of its subsidiaries free and clear of
all liens other than as set forth on Schedule 3.6 hereof.  None of the Company's
subsidiaries  have  outstanding (i) any stock or securities  convertible into or
exchangeable for any shares of capital stock or (ii) any rights to subscribe for
or to purchase,  or any options for the purchase of, or any agreements providing

claims of any character relating to any capital stock or stock or securities.

          3.7.  Material  Adverse  Change.  There has been no  material  adverse
change in the business, prospects or financial standing of the Company since the

          SECTION 4. RESTRICTIONS ON TRANSFERABILITY; REGISTRATION RIGHTS

          The Restricted  Securities  shall not be transferable  except upon the
conditions specified in this Section 4; provided that, notwithstanding any other
provisions of this Section 4, each Holder (and each other Person mentioned below
in this clause)  shall have the right to transfer any  Restricted  Securities to



                                      E-36

<PAGE>



any Affiliate, fund participant,  trust beneficiary,  or limited partner of such
Holder,  any party to any investment  management or other similar agreement with
Trustco or Tamco, any fund, foundation,  trust or other Person for whose benefit
any such  agreement  with Trustco or Tamco relates or any trustee,  custodian or
nominee of or for any such Person  (each a  "Permitted  Transferee").  Each such
transferee  shall be subject to the same  transfer  restrictions  imposed on the
Holders by this  Agreement.  All rights and obligations of the Holders set forth
in  this  Section  4 will  inure  to the  benefit  of and be  binding  upon  any
transferee of the Restricted Securities.

          4.1. Restrictive Legend.  Unless and until otherwise permitted by this
Section 4, each  certificate  for Preferred  Shares issued under this Agreement,
each certificate for any Preferred Shares issued to any subsequent transferee of
any such  certificate,  each  certificate for any Conversion  Shares issued upon
exercise of any Preferred Shares and each certificate for any Conversion  Shares
issued to any subsequent transferee of any such certificate, shall be stamped or
otherwise imprinted with a legend in substantially the following form:

          "The shares  evidenced by this  certificate  have not been  registered
under the Securities Act of 1933, as amended, and may be reoffered and sold only
if  registered  pursuant  to the  provisions  of  said  Securities  Act or if an
exemption from registration is available."

          4.2. Notice of Proposed Transfers.  Prior to any transfer or attempted
transfer of any Restricted  Securities not subject to an effective  registration
statement and not covered by the proviso contained in the introductory paragraph
to Section  4, the  holder of such  Restricted  Certificate  shall give  written
notice to the Company of such holder's  intention to effect such transfer.  Each
such notice (i) shall  describe  the manner and  circumstances  of the  proposed
transfer in sufficient  detail,  and shall contain an  undertaking by the Person
giving such notice to furnish  such other  information  as may be  required,  to
enable  counsel  to  render  the  opinions  referred  to below,  and (ii)  shall
designate the counsel for the Person giving such notice. Except as otherwise set
forth herein,  such Person shall obtain the services of counsel  described below
at its own expense. The Person giving such notice shall submit a copy thereof to
the counsel designated in such notice. If in the opinion of such counsel,  which
is  reasonably  satisfactory  to the  Company,  the  proposed  transfer  of such
Restricted  Securities evidenced by such Restricted  Certificate may be effected
without registration of such Restricted Securities under the Securities Act, the
Company  shall,  within ten (10) business days after delivery of such opinion to
the Company, so notify the holder of such Restricted Certificate and such holder
shall thereupon be entitled to transfer such Restricted Securities in accordance
with the terms of the  notice  delivered  by such  holder to the  Company.  Each
certificate  evidencing the Restricted  Securities  thus to be transferred  (and
each  certificate   evidencing  any  untransferred  balance  of  the  Restricted
Securities evidenced by such Restricted  Certificate) shall bear the restrictive
legend set forth in Section 4.1.

          4.3. Demand Registration.

                    (a) Subject to the limitations  contained in Section 4.7, at
          any time and from  time to time,  the  holders  of at least 51% of the
          outstanding  Series A Preferred  Shares and Conversion  Shares held by
          the TCW  Holders  and the  holders of at least 51% of the  outstanding
          Series A Preferred  Shares and  Conversion  Shares held by the Pacific
          Holders and the Aquila  Holders may give written notice to the Company
          (i) of  their  intention  to  convert  all or  part  of the  Series  A
          Preferred  Shares held by them and to transfer the  Conversion  Shares
          held or obtained by  conversion  of the Series A Preferred  Shares and
          (ii) requesting the registration of said Conversion Shares.

                    (b)  Whenever  the Company  shall have  received a demand to
          effect a registration  pursuant to Section  4.3(a),  the Company shall



                                      E-37

<PAGE>


          promptly  give written  notice of such  proposed  registration  to all
          other Holders. Any such Holder may request in writing that all of such
          Holder's Conversion Shares, or any portion thereof, designated by such
          Holder, be included in the registered offering.

                    (c)  The  Company  shall,  as   expeditiously   as  possible
          following  receipt of a demand pursuant to Section 4.3(a),  effect the
          registration of such  Conversion  Shares under the Securities Act. The
          Sellers of the  Conversion  Shares  shall have the right to select the
          managing   underwriter  or  underwriters  for  the  offering  of  such
          Conversion Shares.

                    (d)  In the  case  of an  underwritten  public  offering  of
          Restricted Securities to be so registered, if the managing underwriter
          advises in its opinion that (i) the inclusion in such  registration of
          some or all of such Common Stock requested to be registered (including
          without  limitation,  securities to be included pursuant to incidental
          or "piggyback"  rights  heretofore or hereafter granted by the Company
          to other  Persons)  will cause the  proceeds or price per share to the
          Sellers  to be reduced  or (ii) that the  number of  securities  to be
          registered at the request of the Sellers  pursuant to this Section 4.3
          plus the number of  securities  sought to be  registered by such other
          Persons is too large a number to be reasonably  sold,  then the number
          of securities to be included in such  registration  will be reduced as
          set forth below:

                    (i) the  number  of  shares  of  Common  Stock  sought to be
          registered by any Holders of Common Stock,  other than the  Conversion
          Shares,  shall be reduced pro rata to the extent  necessary  to reduce
          the number of securities to be registered to the number recommended by
          the managing underwriter (the "Recommended Number");

                    (ii) if the  reduction  provided  for in clause (i) does not
          reduce the number of shares of Common  Stock to be  registered  to the
          Recommended  Number, then the number of Conversion Shares sought to be
          registered by Holders other than the Holders that exercised the demand
          to effect  such  registration  pursuant  to  Section  4.3(a)  shall be
          reduced pro rata, in  proportion  to the number of  Conversion  Shares
          sought to be registered by such Holders of Conversion  Shares,  to the
          extent  necessary to reduce the number of shares of Common Stock to be
          registered to the Recommended Number; and

                    (iii) if the reduction  provided for in clauses (i) and (ii)
          above  does not  reduce  the  number of  shares of Common  Stock to be
          registered to the  Recommended  Number,  then the number of Conversion
          Shares  sought  to  be  registered  shall  be  reduced  pro  rata,  in
          proportion to the number of Conversion  Shares sought to be registered
          by the Holders of such Conversion  Shares,  to the extent necessary to
          reduce the number of shares of Common  Stock to be  registered  to the
          Recommended Number;

provided,  that in no event  shall  the  holders  of the  Conversion  Shares  so
included in such  registration be required to pay any expenses  relating to such
registration,  including,  without limitation, all the expenses described in the
first  paragraph of Section 4.7, which are related to the inclusion of any other
holders' Common Stock in the registration.

                    (e) The Company  will not grant to any Person at any time on
          or after the date  hereof the right (a  "Piggyback  Right") to request
          the  Company to  register  any  securities  of the  Company  under the
          Securities  Act by reason of the  exercise by any Holder of its rights
          under this Section 4.3 unless such Piggyback  Right provides that such
          securities  shall not be  registered  and sold at the same time if the
          managing  underwriter for the respective Sellers believes that sale of
          such  securities  would  adversely  affect  the amount of, or price at
          which,  the respective  Conversion  Shares being registered under this
          Section 4.3 can be sold.

                    (f) The  Company  agrees  (1) not to  effect  any  public or
          private sale or  distribution  of its equity  securities,  including a
          sale pursuant to  Regulation D under the  Securities  Act,  during the
          10-day  period prior to, and during the 120-day  period  beginning on,
          the  closing  date of an  underwritten  offering  made  pursuant  to a
          registration  statement  filed pursuant to this Section 4.3 and (2) to
          cause each holder of its privately placed equity securities  purchased
          from the Company at any time on or after the date of this Agreement to
          agree  not to  effect  any  public  sale or  distribution  of any such
          securities  during such period,  including a sale pursuant to Rule 144
          under  the  Securities  Act  (except  as  part  of  such  underwritten
          registration, if permitted).

                    Except  pursuant to a registration  statement filed pursuant
          to this Section 4.3,  each Holder agrees not to effect any public sale
          or  distribution,  including a sale pursuant to Rule 144 or 144A under
          the  Securities  Act, of any Restricted  Securities  during the 10-day
          period  prior to, and  during the  120-day  period  beginning  on, the
          closing  date  of  an   underwritten   offering  made  pursuant  to  a
          registration statement filed pursuant to this Section 4.3.

                    (g)  The  Company  recognizes  that  money  damages  may  be
          inadequate  to  compensate  Holders for a breach by the Company of its
          obligations under this Section 4.3, and the Company agrees that in the
          event of such a breach  the  Holders  may apply for an  injunction  of
          specific  performance or the granting of such other equitable remedies
          as may be awarded  by a court of  competent  jurisdiction  in order to
          afford  Holders the  benefits of this Section 4.3 and that the Company
          shall not  object to such  application,  entry of such  injunction  or
          granting of such other  equitable  remedies on the grounds  that money
          damages will be sufficient to compensate the Holders.

          4.4. Piggy-Back Registration.

                    (a) Subject to the limitations  contained in Section 4.7, if
          the Company at any time  proposes to  register  any of its  securities
          under the Securities Act (other than a registration effected solely to
          implement an employee benefit plan, a registration of the Notes or any
          other  registration on Form S-4),  whether of its own accord or at the
          request of any holder or holders of such securities, it will each such
          time give  written  notice to all  holders  of  outstanding  Preferred
          Shares and Conversion Shares of its intention so to do.

                    (b) Upon the  written  request of a holder or holders of any
          such Preferred Shares and Conversion Shares given within 30 days after
          receipt of any such notice (stating the intended method of disposition
          of such securities by the prospective Seller or Sellers),  the Company
          will use its best efforts to cause all Conversion  Shares, the holders
          of  which  shall  have  so  requested   registration  thereof,  to  be
          registered  under the Securities  Act, all to the extent  requisite to
          permit the sale or other  disposition (in accordance with the intended
          methods thereof as aforesaid) by the prospective  Seller or Sellers of
          the Conversion Shares so registered;  provided,  however,  the Company
          may  elect  not to  file a  registration  statement  pursuant  to this
          Section 4.4 or may withdraw any registration  statement filed pursuant
          to this Section 4.4 at any time prior to the  effective  date thereof.
          In the case of an underwritten  public equity offering by the Company,
          each Seller shall, if requested by the managing underwriter, agree not
          to sell  publicly  any equity  securities  of the Company held by such
          Seller (other than the Conversion  Shares so registered)  for a period
          of up to 120 days  following  the effective  date of the  registration
          statement relating to such offering.

                    (c) If the managing  underwriter for the respective offering
          advises that the inclusion in such  registration of some or all of the
          Conversion Shares sought to be registered by the Seller in its opinion
          will  cause  the  proceeds  or  price  per  unit  the  Company  or the

          requesting  or demanding  holder of  securities  will derive from such
          registration  to be  reduced or that the  number of  securities  to be
          registered  at the  instance  of the  Company  or such  requesting  or
          demanding holder plus the number of securities sought to be registered
          by the Sellers is too large a number to be reasonably  sold,  then the
          number of  securities  to be  included  in such  registration  will be
          reduced as set forth below:

                    (i) the  number  of  shares  of  Common  Stock  sought to be
          registered by any holders of Common Stock,  other than the  Conversion
          Shares,  shall be reduced pro rata to the extent  necessary  to reduce
          the number of securities to be registered to the Recommended Number;

                    (ii) if the reduction  provided for in clause (i) above does
          not  reduce  the  number  of   securities  to  be  registered  to  the
          Recommended  Number,  then the  number of shares of the  Common  Stock
          sought to be issued and  registered on account of the Company shall be
          reduced  to the  extent  necessary  to reduce  the number of shares of
          Common Stock to be registered  to the  Recommended  Number;  provided,
          however,  that this clause (ii) shall be of no effect with  respect to
          the registration and sale of such Common Stock by the Company which is
          necessary  to  repay  any debt or  obligation  of the  Company  or its
          subsidiaries  then  becoming  due and payable or which is necessary to
          finance the  acquisition  of assets or a majority  of the  outstanding
          stock of another  corporation by the Company or its subsidiaries which
          acquisition will be consummated  within 6 months of the effective date
          of such  registration;  and  (iii) if the  reduction  provided  for in
          clauses  (i) and (ii)  above  does not  reduce the number of shares of
          Common Stock to be  registered  to the  Recommended  Number,  then the
          number of Conversion  Shares sought to be registered  shall be reduced
          pro rata, in  proportion to the number of Conversion  Shares sought to
          be  registered  by the holders  thereof,  to the extent  necessary  to
          reduce the number of shares of Common  Stock to be  registered  to the
          Recommended Number.

                    (d) The Company  will not grant to any Person at any time on
          or after the date  hereof the right to request the Company to register
          any  securities  of the Company under the  Securities  Act unless such
          right provides that such  securities  shall not be registered and sold
          at the  same  time if the  managing  underwriter  for  the  respective
          sellers  believes that sale of such securities  would adversely affect
          the amount of, or price at which,  the  respective  Conversion  Shares
          being registered under this Section 4.4 can be sold.

          4.5.  Registration  of  Dividend  Shares.  The  Company  shall cause a
registration statement to be filed pursuant to Rule 415 under the Securities Act
(the "Shelf  Registration  Statement") and to be declared effective prior to the
issuance of Dividend Shares to any Holder,  which Shelf  Registration  Statement
shall provide for resales of all Dividend  Shares that are issued by the Company
to the Holders and which Shelf  Registration  Statement  shall remain  effective
until the earlier of (a) the date all such Dividend  Shares have been sold under
such Shelf  Registration  Statement or (b) the date such Dividend  Shares can be
sold pursuant to Rule 144(k) promulgated under the Securities Act.

          4.6.  Registration  Procedures.  (a) If and  whenever  the  Company is
required by the  provisions  of this Section 4 to use its best efforts to effect
the  registration of any of the Conversion  Shares or to effect the registration
of the  Dividend  Shares under the  Securities  Act, the Company will (except as
otherwise provided in this Agreement), as expeditiously as possible:

                    (i) cooperate with any underwriters for, and the Sellers of,
          such  Common  Shares,  and  will  enter  into a  usual  and  customary
          underwriting  agreement  with respect  thereto and take all such other
          reasonable  actions as are necessary or advisable to permit,  expedite
          and  facilitate  the  disposition  of such Common Shares in the manner
          contemplated by the related registration statement in each case to the
          same extent as if all the securities  then being  offered were for the

          account of the Company and the Company  will  provide to any Seller of
          Common  Shares,  any  underwriter  participating  in any  distribution
          thereof  pursuant  to a  registration  statement,  and  any  attorney,
          accountant  or other  agent  retained  by any  Seller or  underwriter,
          reasonable  access to  appropriate  Company  officers and employees to
          answer questions and to supply information reasonably requested by any
          such Seller, underwriter,  attorney, accountant or agent in connection
          with such registration statement;

                    (ii)  furnish  or cause to be  furnished  to each  Seller of
          Common  Shares  covered  by  such   registration   statement  and  the
          underwriters,  if any, addressed to such Sellers and the underwriters,
          if any,  such  opinion of counsel  for the  Company,  and a  "comfort"
          letter signed by the independent public accountants who have certified
          the  Company's  financial  statements  included  in  the  registration
          statement  in  each  case  covering  matters  customarily  covered  in
          opinions and "comfort" letters requested in underwritten offerings and
          such other matters as may be  reasonably  requested by the Sellers and
          underwriters, if any;

                    (iii)  prepare and file with the  Commission a  registration
          statement with respect to such  securities and use its best efforts to
          cause such  registration  statement to become and remain  continuously
          effective  and  provide all  requisite  financial  statements  for the
          period specified in paragraph (b) of this Section 4.6; and prepare and
          file with the  Commission  such  amendments  and  supplements  to such
          registration statement and the prospectus used in connection therewith
          (including  without  limitation such amendments and supplements as the
          Sellers may deem necessary in their  reasonable  discretion) as may be
          necessary to keep such registration  statement  continuously effective
          and to comply with the  provisions of the  Securities Act with respect
          to the sale or other  disposition  of all  securities  covered by such
          registration   statement  whenever  the  Seller  or  Sellers  of  such
          securities  shall  desire to sell or  otherwise  dispose  of the same;
          provided  that no such  registration  statement  will be  filed by the
          Company until counsel for the Sellers of securities  included  therein
          shall  have had a  reasonable  opportunity  to review  the same and to
          exercise their rights under clause (i) above with respect  thereto and
          no amendment to any such registration statement naming such Sellers as
          selling  shareholders  shall be filed with the  Commission  until such
          Sellers shall have had at least seven days to review such registration
          statement as originally  filed and  theretofore  amended,  to exercise
          their rights under clause (i) above and to approve or  disapprove  any
          portion of such registration statement describing or referring to such
          Sellers;

                    (iv)  furnish  to each  Seller  such  numbers of copies of a
          summary  prospectus  or  other  prospectus,  including  a  preliminary
          prospectus, in conformity with the requirements of the Securities Act,
          and such other  documents,  as such Seller may  reasonably  request in
          order  to  facilitate  the  public  sale or other  disposition  of the
          securities owned by such Seller;

                    (v)  use  its  best  efforts  to  register  or  qualify  the
          securities  covered by such  registration  statement  under such other
          securities or blue sky laws of such jurisdictions as each Seller shall
          request,  and do any  and all  other  acts  and  things  which  may be
          necessary or advisable to enable such Seller to consummate  the public
          sale or other  disposition  in such  jurisdictions  of the  securities
          owned by such Seller,  except that the Company  shall not for any such
          purpose be required to qualify to do business as a foreign corporation
          in any jurisdiction  wherein it is not so qualified or to file therein
          any general consent to service;

                    (vi)  in  the  event  of the  issuance  of  any  stop  order
          suspending the  effectiveness of any registration  statement or of any
          order suspending or preventing the use of any prospectus or suspending
          the  qualification of any Common Shares for sale in any  jurisdiction,
          use its best efforts promptly to obtain its withdrawal;


                                      E-41

<PAGE>



                    (vii)  otherwise  use its best  efforts  to comply  with all
          applicable rules and regulations of the Commission, and make available
          to its  security  holders,  as  soon  as  reasonably  practicable,  an
          earnings  statement  covering  the period of at least  twelve  months,
          beginning with the first fiscal quarter  beginning after the effective
          date of the  registration  statement,  which earnings  statement shall
          satisfy the provisions of Section 11(a) of the Securities Act; and

                    (viii) list such  securities on any  securities  exchange on
          which any stock of the Company is then listed,  if the listing of such
          securities is then permitted under the rules of such exchange;

                    (b)  Notwithstanding  any other provision of this Section 4,
          the Company shall not be required to maintain the effectiveness of (i)
          any  registration  statement filed by the Company  pursuant to Section
          4.3 or Section  4.4  hereof for a period in excess of two years  (plus
          any period during which the  effectiveness  of such  registration  has
          been  suspended)  or (ii)  any  registration  statement  filed  by the
          Company  pursuant  to Section  4.5 for a period in excess of two years
          (plus any period during which the  effectiveness of such  registration
          has been  suspended)  following the later of (a) the date on which the
          Company  issues shares of Common Stock in payment of a dividend on the
          Preferred Shares for the last dividend payment made in Common Stock by
          the Company with respect to the  Preferred  Shares and (b) the date on
          which the Company  issues  shares of Common Stock to redeem all of the
          then issued and outstanding  Preferred Shares. From time to time after
          a transfer of Shares pursuant to a registration  statement the Company
          will file all reports  required to be filed by it under the Securities
          Act and the Securities Exchange Act of 1934, as amended, and the rules
          and regulations  adopted by the Commission  thereunder,  and will take
          such  further  action as any holder or  holders  of Common  Shares may
          reasonably request,  all to the extent required to enable such holders
          to sell Common Shares  pursuant to Rule 144 and Rule 144A  promulgated
          under the  Securities  Act (or any  successor  thereto).  Upon written
          request,  the Company will deliver to such holders a written statement
          as to whether it has complied with such requirements.

          4.7. Expenses;  Limitations on Registration. The Company shall pay all
expenses incident to the Company's  performance of its obligations in connection
with any  registration  of the  Sellers'  Common  Shares  under  this  Agreement
including,   without   limitation,   (i)  printing   expenses,   (ii)  fees  and
disbursements of counsel for the Company, (iii) fees of the National Association
of  Securities  Dealers,  Inc.  in  connection  with its review of any  offering
contemplated in any registration statement,  (iv) expenses of any special audits
to which the  Company  shall agree or which  shall be  necessary  to comply with
governmental  requirements  in connection  with any such  registration,  (v) all
registration  and filing fees for the Sellers'  Common  Shares under Federal and
State  securities  laws,  (vi) expenses of complying with the securities or blue
sky laws of any jurisdictions pursuant to Section 4.6(a)(v),  and (vii) fees and
expenses  of not more than one special  counsel for the Seller or Sellers  whose
Common  Shares are included in such  registration,  such  special  counsel to be
selected by the Holder(s) of a majority of such Common  Shares  included in such
registration.

          It shall be a condition  precedent to the obligation of the Company to
take any action  pursuant to this Section 4 in respect of the Conversion  Shares
which are to be  registered  at the request of any  prospective  Seller that (i)
subject to the immediately preceding paragraph,  the Company shall have received
an undertaking  satisfactory to it from such prospective  Seller to pay, or have
deducted  from the proceeds  from the sale of  Conversion  Shares  pursuant to a
registration,  all expenses to be incurred by or for the account of and required
to be paid by such Seller, and (ii) such prospective Seller shall furnish to the
Company such  information  regarding the securities  held by such Seller and the
intended method of disposition  thereof as the Company shall reasonably  request
and as shall be  required  in  connection  with  the  action  to be taken by the
Company.

          The TCW Holders of  Preferred  Shares and  Conversion  Shares shall be
entitled to an aggregate  of two  effective  registrations  pursuant to requests
made under  Section 4.3;  provided that in the case any TCW Holder shall acquire
any Conversion  Shares by conversion of such Preferred  Stock following a Notice
of Redemption  (as defined in the  Certificate  of  Designation)  the holders of
Preferred  Shares and  Conversion  Shares  shall be entitled to an  aggregate of
three  effective  registrations  pursuant to requests  made under  Section  4.3;
provided, further, that any registration request made by the requisite number of
Holders, as set forth in the first paragraph of Section 4.3, which request shall
be  withdrawn  (other  than by reason of the  Company's  failure to perform  its
obligations  hereunder or a material adverse change in its financial position or
business)  by the holders of at least 75% of the shares  evidenced or covered by
the Conversion Shares sought to be registered, after the respective registration
statement  shall have  become  effective,  shall be  treated  as an  "effective"
registration for purposes hereof.

          The Pacific  Holders and the Aquila  Holders of  Preferred  Shares and
Conversion   Shares  shall  be  entitled  to  an  aggregate  of  one   effective
registration  pursuant to a request made under Section 4.3; provided that in the
case any Pacific Holder or Aquila Holder shall acquire any Conversion  Shares by
conversion of such Preferred  Stock following a Notice of Redemption (as defined
in  the  Certificate  of  Designation)  the  holders  of  Preferred  Shares  and
Conversion   Shares  shall  be  entitled  to  an  aggregate  of  two   effective
registrations  pursuant to requests made under Section 4.3;  provided,  further,
that any registration  request made by the requisite  number of Holders,  as set
forth in the first  paragraph of Section 4.3,  which  request shall be withdrawn
(other  than by reason of the  Company's  failure  to  perform  its  obligations
hereunder or a material adverse change in its financial position or business) by
the holders of at least 75% of the shares evidenced or covered by the Conversion
Shares sought to be  registered,  after the  respective  registration  statement
shall have become effective, shall be treated as an "effective" registration for
purposes hereof.

          The  Company  agrees  that it will not file a  registration  statement
under the Securities  Act,  either for  securities  held by any of the Company's
securityholders  other than holders of Preferred Shares and Common Shares or for
securities  newly issued by the Company,  until 30 days after the effective date
of any  registration  statement  filed  pursuant  to the  request of a Seller or
Sellers made under Section 4.3.

          4.8. Indemnification.

          4.8.1. In the event of any registration of any of its securities under
the Securities  Act pursuant to this Section 4, the Company shall  indemnify and
hold  harmless  the  Seller of such  Common  Shares,  such  Seller's  directors,
officers,  employees,  agents,  and each other person, if any, who controls such
Seller  within  the  meaning of the  Securities  Act (a  "Controlling  Person"),
against any losses, claims,  damages or liabilities,  joint or several, to which
such  Seller or any such  director or officer or  Controlling  Person may become
subject under the Securities Act or any other statute or at common law,  insofar
as such losses,  claims,  damages or liabilities (or actions in respect thereof)
arise out of or are based upon (i) alleged untrue statement of any material fact
contained,  on the effective date thereof,  in any registration  statement under
which such  securities  were  registered  under the  Securities  Act,  or in any
preliminary  prospectus or final prospectus  contained therein, or any amendment
or supplement thereto, or (ii) alleged omission to state therein a material fact
required to be stated  therein or necessary to make the  statements  therein not
misleading,  and shall  reimburse  such  Seller  or such  director,  officer  or
Controlling  Person for any legal or any other expenses  reasonably  incurred by
such Seller or such director,  officer or Controlling  Person in connection with
investigating or defending any such loss,  claim,  damage,  liability or action;
provided,  however, that the Company shall not be liable in any such case to the
extent that any such loss, claim,  damage or liability arises out of or is based
upon any alleged untrue statement or alleged omission made in such  registration
statement,  preliminary  prospectus,  prospectus,  or amendment or supplement in
reliance  upon and in  conformity  with  written  information  furnished  to the
Company through an instrument duly executed by such Seller  specifically for use
therein.  Such indemnity shall remain in full force and effect regardless of any
investigation  made by or on behalf of such Seller or such director,  officer or
Controlling  Person,  and shall survive the transfer of such  securities by such
Seller.

          4.8.2. Each holder of any Common Shares shall, by acceptance  thereof,
indemnify  and hold  harmless the Company,  its  directors and officers and each
other  person,  if any,  who controls  the Company  against any losses,  claims,
damages  or  liabilities,  joint or  several,  to which the  Company or any such
director or officer or any such person may become  subject under the  Securities
Act or any other  statute  or at common  law,  insofar as such  losses,  claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon (i) any untrue statement or omission of any material fact contained, on the
effective date thereof,  in any  registration  statement under which  securities
were registered  under the Securities  Act, or in any preliminary  prospectus or
final prospectus  contained therein,  or any amendment or supplement thereto, or
(ii) any omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading,  in each case to the
extent,  but only to the extent  that such  untrue  statement  or  omission  was
contained in written information  furnished to the Company through an instrument
duly executed by such holder  specifically for use therein,  and shall reimburse
the Company or such director, officer or other person for any legal or any other
expenses  reasonably  incurred in connection with investigating or defending any
such loss, claim, damage, liability or action.

          4.8.3.  Indemnification similar to that specified in Subsections 4.8.1
and 4.8.2 shall be given by the  Company  and each  holder of any Common  Shares
(with  such  modifications  as shall be  appropriate)  to any  underwriter  with
respect to any required registration or other qualification of any Common Shares
under any Federal or state law or  regulation  of  governmental  authority.  The
indemnity and expense reimbursements  obligations of the Company and the Holders
under  Subsections  4.8.1 and 4.8.2 shall be in addition  to any  liability  the
Company and the Holders may otherwise have.

          4.8.4.   Each  Person  (an   "Indemnitor")  who  under  the  preceding
provisions  of  this  Section  4.8  agrees  to  indemnify   another  Person  (an
"Indemnitee")  shall  have the  right,  subject  to the  provisions  hereto,  to
designate  counsel  (acceptable  to  the  Indemnitee)  to  defend  any  case  or
proceeding  against the Indemnitee  arising in respect of any claim of liability


                                      E-44

<PAGE>


for which such  indemnification  may be claimed,  to the end that duplication of
legal expense may be minimized;  provided that, if the  Indemnitee  notifies the
Indemnitor  that the former  has been  advised  by its  counsel  that any single
counsel  in such  case or  proceeding  would  have a  conflict  of  interest  in
representing  both  the  Indemnitor  and  the  Indemnitee,  the  Indemnitee  may
designate  its own  counsel  in such case or  proceeding  and,  to the extent so
provided  above in this Section 4.8,  shall be entitled to be reimbursed for its
legal expenses  reasonably  incurred in connection with defending itself in such
case or proceeding.

          4.9.  Termination  of  Restrictions.   Notwithstanding  the  foregoing
provisions  of this Section 4, the  restrictions  imposed by this Section 4 upon
the transferability of the Restricted Securities shall cease and terminate as to
any particular Restricted Security when such Restricted Security shall have been
effectively  registered  under the Securities Act and sold by the holder thereof
in accordance with such  registration or sold under Rule 144 or 144A promulgated
by the  Commission.  Whenever the  restrictions  imposed by this Section 4 shall
terminate as to any Restricted Certificate,  as hereinabove provided, the holder
thereof shall be entitled to receive from the Company,  without  expense,  a new
certificate not bearing the restrictive  legend  otherwise  required to be borne
thereby.

          4.10.  Rule 144.  At all  times,  in order to permit  the  holders  of
Preferred Shares and Common Shares to sell the same, if they so desire, pursuant
to Rule 144 or 144A  promulgated  by the  Commission  (or any  successor to such
rule),  the Company will comply with all rules and regulations of the Commission
applicable in connection  with use of Rule 144 and 144A (or any successor  rules
thereto),  including the provision of information concerning the Company and the
timely  filing  of all  reports  with the  Commission  in order to  enable  such
holders,  if they so elect,  to utilize  Rule 144 or 144A,  and the Company will
cause any restrictive legends to be removed and any transfer  restrictions to be
rescinded with respect to any sale of Preferred Shares or Common Shares which is
exempt from registration under the Securities Act pursuant to Rule 144 or 144A.

          SECTION 5. COVENANTS OF THE COMPANY

          5.1. Delivery  Expenses.  If any Holder surrenders any certificate for
Preferred  Shares,  Conversion  Shares or  Dividend  Shares to the  Company or a
transfer   agent  of  the  Company  for  exchange  for   instruments   of  other
denominations or registered in another name or names, the Company will,  subject
to the provisions of Section 4, cause such new instruments to be issued and will
pay the cost of  delivering  to or from the office of the Holder  from or to the
Company or its transfer agent, duly insured, the surrendered  instrument and any
new  instruments  issued in  substitution  or  replacement  for the  surrendered
instrument.

          5.2. Taxes. The Company will pay all taxes (other than Federal,  State
or local income taxes) which may be payable in connection with the execution and
delivery of this Agreement or the issuance and sale of the Preferred Shares, the
Conversion  Shares and the Dividend  Shares  hereunder or in connection with any
modification of the Preferred  Shares,  Conversion Shares or Dividend Shares and
will save the Holders harmless without limitation as to time against any and all
liabilities  with respect to or resulting from any delay in paying,  or omission
to pay such taxes.  The  obligations of the Company under this Section 5.2 shall
survive  any  redemption,   repurchase  or  acquisition  of  Preferred   Shares,
Conversion  Shares or Dividend Shares by the Company and the termination of this
Agreement.  5.3.  Replacement  of  Instruments.  Upon  receipt by the Company of
evidence reasonably  satisfactory to it of the ownership of and the loss, theft,
destruction  or  mutilation of any  certificate  or  instrument  evidencing  any
Preferred Shares, Conversion Shares or Dividend Shares, and

                    (a) in the case of loss, theft or destruction,  of indemnity
          reasonably satisfactory to it (provided that, if the owner of the same

          agreement of indemnity shall be deemed to be satisfactory), or

                    (b)  in  the  case  of   mutilation,   upon   surrender  and
          cancellation thereof,

the  Company,  at its expense,  will  execute,  register  and  deliver,  in lieu
thereof,  a new  certificate  or instrument for (or covering the purchase of) an
equal number of shares of Preferred Shares, Conversion Shares or Dividend Shares
 .

          5.4. Restrictions on Certain Actions.  Prior to the day next following
the issuance of Preferred Shares hereunder the Company will not:

                    (a) pay or  declare  any  dividend  payable in shares of its
          common stock or take any other action  which,  if taken after the date
          of such issuance,  would result under the terms of the Preferred Stock
          in a  change  in the  number  of  Conversion  Shares  into  which  the
          Preferred Shares may be converted; or

                    (b) make any amendment to the Articles of  Incorporation  of
          the Company, or file any resolution of the board of directors with the
          Nevada  Secretary  of State  containing  any  provisions,  which would
          materially and adversely  affect or otherwise impair the rights of the
          holders of the Preferred Shares.

          5.5. Use of Proceeds.  The Company  shall use the proceeds of the sale
of the Preferred Shares to repay amounts outstanding under the Credit Agreement.

          5.6. Rights  Agreement.  The Company will not, without the affirmative
vote or  consent  of the  Requisite  Holders,  supplement,  amend or repeal  any
provision of the Rights Agreement,  or adopt any other agreement or plan similar
to the Rights Agreement,  which could materially adversely affect the Holders of
the Preferred  Stock, the Conversion  Shares or Dividend  Shares,  in their sole
discretion.

          5.7.  Maintenance of NYSE Listing.  For as long as any Purchaser holds
any Preferred Shares,  Conversion  Shares or Dividend Shares,  the Company shall
cause the Common Stock to be continuously  listed on the New York Stock Exchange
or, if the Common Stock is delisted from the New York Stock Exchange, the NASDAQ
National  Market  System or the  American  Stock  Exchange;  provided,  that the
Company shall not be liable for a failure to maintain such listing if the Common
Stock  of  the  Company  fails  to  meet  the  eligibility  requirements  of the
particular  exchange  if and  only  if the  failure  to  meet  such  eligibility
requirements shall not have been caused by any action of the Company.

          5.8.  Election of  Directors;  Maintenance  of Directors  and Officers
Insurance.

                    (a) The Company and its Board of  Directors  shall cause the
          Board of  Directors of the Company  following  the  redemption  of the
          Series A Preferred  Shares  pursuant  to the terms of the  Articles of
          Incorporation  and  Certificate of Designation to at all times include
          as  members  of  the  Board  of  Directors  a  number  of  individuals
          designated  as  directors  by  Purchasers  on  behalf  of the  initial
          purchasers  of the  Preferred  Shares  pursuant to this  Agreement and
          their Permitted  Transferees equal to the number of directors that the
          Holders of  Preferred  Shares  were  entitled  to elect  prior to such
          redemption  pursuant to the terms of the Articles of Incorporation and
          the Certificate of Designation. The obligations of the Company and the
          Board of  Directors  to cause the Board of Directors of the Company to
          be so constituted shall continue for so long as the initial purchasers
          of the Preferred Shares pursuant to this Agreement and their Permitted
          Transferees hold at least 20% of the issued and outstanding  shares of
          Common  Stock  of the  Company;  provided,  that  in  calculating  the
          percentage of Common Stock held by such initial  purchasers  and their
          Permitted  Transferees,  only  Common  Stock (x) issued by the Company
          upon the conversion or redemption of the Preferred  Shares or (y) paid
          by the Company as a dividend on the Preferred Shares shall be included


                                      E-46

<PAGE>



in such  calculation.  In the event that such  Holders at anytime hold less than
20% of the issued and  outstanding  shares of Common Stock of the  Company,  the
Company and its Board of Directors shall cause the Board of Directors to include
as members of the Board of Directors  one director  designated  by Purchasers on
behalf of such  Holders  for each 5% of the  issued  and  outstanding  shares of
Common Stock of the Company held by such Holders;  provided, that in calculating
the  percentage  of  Common  Stock  held by such  initial  purchasers  and their
Permitted  Transferees,  only Common  Stock (x) issued by the  Company  upon the
conversion or redemption of the Preferred Shares or (y) paid by the Company as a
dividend on the  Preferred  Shares  shall be included in such  calculation.  The
Company and the Board of Directors  of the Company  agree that at all times that
the Holders  have the right to  designate  directors  pursuant  to this  Section
5.8(a), the number of directors  constituting the whole Board of Directors shall
be no greater than six directors  plus the number of Directors  that the Holders
are  entitled to elect  pursuant to the terms of this  Section  5.8(a).  If such
Holders  designate  fewer  directors  than allowed by this Section  5.8(a),  the
directors  designated by such Holders shall nonetheless have the number of votes
equal to the  number  of  directors  that such  Holders  could  have  designated
pursuant this Section 5.8(a) so that at any meeting of the Board of Directors of
the Company each director  designated  by such Holders  pursuant to this Section
5.8(a) shall have the number of votes equal to the number of directors that such
Holders could have  designated  pursuant to this Section 5.8(a) (the  "Available
Director  Seats")  divided by the actual number of directors  designated by such
Holders  pursuant to this Section 5.8(a) and attending such meeting (the "Actual
Directors") and, for purposes of determining whether a quorum is present at such
meeting,  each such director that was  designated by such Holders and is present
at such meeting shall be counted as a number of directors equal to the number of
Available Director Seats divided by the number of Actual Directors.

                    (b) So long as the Holders are entitled to elect one or more
          directors  pursuant to the terms of this  Section 5.8 and for a period
          of three years  after such time as the Holders are no longer  entitled
          to elect any  directors,  the Company shall  maintain  director's  and
          officer's  insurance  providing  for such amount of coverage  and such
          terms as shall be  satisfactory  to Purchasers.  In the event that the
          Company (i) consolidates  with or merges with or into any other person
          and shall not be the continuing or surviving  corporation or entity of
          such  consolidation  or merger or (ii) transfers all or  substantially
          all of its  properties  and assets to any person  then,  in each case,
          proper  provision  shall be made such that the  successors and assigns
          shall assume the obligations set forth in this Section 5.8(b).

          5.9.  Shareholder  Approval.  The Company  shall call a meeting of its
shareholders  to be held no later than July 31,  1999 for the  purpose of voting
upon the  approval  of the  issuance  of the  Series B  Conversion  Shares,  the
Conversion Shares and the Dividend Shares. The Company will through its Board of
Directors  recommend to its  shareholders the approval of such matters and shall
not  withdraw,  modify or change its  recommendation  in any  manner  that would
adversely  effect the  ability of the  Company to issue the Series B  Conversion
Shares,  Conversion Shares or the Dividend Shares.  The Purchasers agree to vote
all of their Series A Preferred  Shares in favor of such  recommendation  of the
Board of Directors  authorizing the issuance of the Series B Conversion  Shares,
the Conversion Shares and the Dividend Shares.

          5.10 Issuance of  Additional  Series A Preferred  Shares.  The Company
shall not issue any  additional  shares of Series A Preferred  Shares other than
the Series B Conversion Shares.

by the Holders and shall survive the issuance of the Preferred Shares regardless
of any investigation made by or on behalf of the Holders.  All statements in any
such   certificate   or  other   instrument   so  delivered   shall   constitute
representations and warranties by the Company hereunder.

          All  representations,  warranties  and  covenants  made by the Holders

survive the issuance to the Holders of the  Preferred  Shares  regardless of any

issuance to the  Holders of the  Preferred  Shares,  the  Conversion  Shares and

observance  of any term of this  Agreement  may be  waived,  but  only  with the
written consent of the Requisite Holders. No failure or delay on the part of the
Holders in exercising any right,  power or remedy  hereunder  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,  power or  remedy.  The  remedies  provided  for herein are
cumulative  and are not  exclusive of any remedies  that may be available to the
Holders  at law or in  equity or  otherwise.  No  waiver  of or  consent  to any

Agreement  may be signed by the parties,  each of which shall be an original but
all of which together shall constitute one and the same instrument.

          6.6. Severability. In the event that any one or more of the provisions
contained  herein,  or the  application  thereof  in any  circumstance,  is held
invalid, illegal or unenforceable,  the validity, legality and enforceability of

this  Agreement.  Such terms,  together  with the other terms defined in Section
1.1,  shall  include both the singular and the plural forms thereof and shall be
construed  accordingly.  All computations  required  hereunder and all financial
terms used herein shall be made or construed in accordance with GAAP unless such
principles are inconsistent with the express requirements of this Agreement.

     SECTION 2. The Commitments.

     2.1 Advances. (a) Each Bank agrees, for itself only, to lend and to relend,
and to participate in Letter of Credit Advances pursuant to Section 3.1, in each
case subject to the terms and conditions of this Agreement,  to the Borrowers at
any time and from time to time from the  Effective  Date  until the  Termination
Date amounts equal to such Bank's Pro Rata Share of such  aggregate  Advances as
any Borrower  may from time to time  request,  provided  that no Advances may be
made if the aggregate  outstanding amount of all Advances to all Borrowers would
exceed the lesser of the Commitments or the Borrowing Base;  provided,  however,
that the aggregate principal amount of Letters of Credit outstanding at any time
shall not exceed $5,000,000.  Each Loan made hereunder shall be evidenced by the
Notes, which shall mature and bear interest as set forth in Section 4 hereof and
in such Notes.  On the Effective  Date, the Borrowers shall issue and deliver to
each Bank a Note in the  principal  amount  of such  Bank's  Commitment  for the
period  beginning on the Effective Date. Each Loan which is a Floating Rate Loan
shall be in a minimum  amount of $500,000 and in integral  multiples of $100,000
and each  Loan  which is a  Eurodollar  Loan  shall be in a  minimum  amount  of
$1,000,000 and in integral multiples of $1,000,000.  No more than ten Eurodollar
Interest  Periods  shall be permitted  to exist at any one time.  Subject to the



                                      E-68

<PAGE>



terms and onditions of this Agreement, the Borrowers may borrow, prepay pursuant
to Section 4.1(b) and reborrow under this Section 2.1(a).

          (b) For  purposes of this  Agreement,  a Letter of Credit  Advance (i)
shall be deemed  outstanding in an amount equal to the sum of the maximum amount
available to be drawn under the related Letter of Credit on or after the date of
determination and on or before the stated expiry date thereof plus the amount of
any draws under such Letter of Credit that have not been  reimbursed as provided
in Section 3.3 and (ii) shall be deemed  outstanding  at all times on and before
such stated  expiry date or such earlier date on which all amounts  available to
be drawn under such Letter of Credit have been fully drawn, and thereafter until
all related reimbursement obligations have been paid pursuant to Section 3.3. As
provided in Section  3.3,  upon each payment made by the Agent in respect of any
draft or other demand for payment under any Letter of Credit,  the amount of any
Letter of Credit Advance outstanding  immediately prior to such payment shall be
automatically  reduced by the amount of each Loan deemed  advanced in respect of
the related reimbursement obligation of the Borrowers.

          (c) The  Borrowers  shall  have the right to  terminate  or reduce the
Commitments  at any time and from time to time,  provided that (i) the Borrowers
shall give notice of such  termination or reduction to the Agent  specifying the
amount  and  effective  date  thereof,   (ii)  each  partial  reduction  of  the
Commitments shall be in a minimum amount of $1,000,000 and in integral multiples
of  $1,000,000   and  shall  reduce  the   Commitments   of  all  of  the  Banks
proportionally in accordance with the respective Commitment amounts of each such
Bank,  (iii)  no such  termination  or  reduction,  either  in whole or part and
including without limitation any termination, shall be permitted with respect to
any  portion  of the  Commitments  as to which a request  for  Advances  is then
pending, and (iv) the Commitments may not be terminated if any Advances are then
outstanding  and may not be reduced below the principal  amount of Advances then
outstanding. The Commitments or any portion thereof so terminated or reduced may
not be reinstated.  Any Borrower may request Advances without the consent of any
other  Borrower,  and  each  Borrower  consents  to and  approves  any  Advances
requested by any other Borrower.  The Advances  hereunder  replace the revolving
credit loans and letters of credit outstanding pursuant to Section 2.1(a) of the
Existing Credit Agreement and provide additional credit as described above.

          (d) This Agreement amends and restates the Existing Credit  Agreement,
and all Advances  and Letters of Credit  outstanding  under the Existing  Credit
Agreement shall  constitute  Advances and Letters of Credit under this Agreement
and all fees and other  obligations  accrued under the Existing Credit Agreement
will continue to accrue and be paid under this Agreement. As stated in the Notes
and the Consent and  Amendment  to Security  Documents,  the  Advances and other
obligations  pursuant  hereto are issued in  exchange  and  replacement  for the
Advances and other obligations under an Existing Credit Agreement,  shall not be
a novation or satisfaction  thereof and shall be entitled to the same collateral
with the same priority.

     SECTION 3. The Advances.

     3.1 Disbursement of Advances.  (a) Borrowers shall give notice to the Agent
of each requested Advance in substantially  the form of Exhibit C hereto,  which
notice  given shall be received by the Agent not later than 10:00 a.m.  (Chicago
time), (i) three Business Days prior to the date such Advance is requested to be
made if such Advance is to be made as a Eurodollar  Loan,  (ii) one Business Day
prior to the date such  Advance is requested to be made if such Advance is to be
made as a Floating  Rate Loan and (iii)  three  Business  Days prior to the date
such  Advance is to be made if such  Advance is to be made as a Letter of Credit
Advance.  Each  such  notice  given  shall be  irrevocable  and  binding  on the
Borrowers,  any such notice must  specify  the  Advance  Date,  which shall be a
Business  Day,  the  aggregate  amount  of such  Advance,  the  Type of  Advance
selected,  in the case of any Eurodollar  Loan, the Eurodollar  Interest  Period



                                      E-69

<PAGE>



applicable  thereto,  and in the case of any Letter of Credit Advance such other
information  and documents with respect thereto as may be required by the Agent.
The Agent shall  provide  notice of such  requested  Advance to each Bank on the
same  Business Day such notice is received  from the  Borrowers.  Subject to the
terms and conditions of this Agreement,  the Agent shall, on the date any Letter
of Credit Advance is requested to be made, issue the related Letter of Credit on
behalf of the Banks for the account of the designated Borrower.  Notwithstanding
anything  herein to the  contrary,  the Agent may decline to issue any requested
Letter of Credit on the basis that the  beneficiary,  the purpose of issuance or
the terms or the  conditions  of drawing  are illegal or contrary to a policy of
the Agent.

          (b) Floating  Rate Loans shall  continue as Floating Rate Loans unless
and until such Floating Rate Loans are converted  into  Eurodollar  Loans.  Each
Eurodollar  Loan of any Type shall  continue as a  Eurodollar  Loan of such Type
until the end of the then  applicable  Interest Period  therefor,  at which time
such Eurodollar Loan shall be automatically  converted into a Floating Rate Loan
unless the Borrower shall have given the Agent a Conversion/Continuation  Notice
requesting that, at the end of such Interest Period, such Eurodollar Loan either
continue  as a  Eurodollar  Loan for the same or another  Interest  Period or be
converted into a Loan of another Type.  Subject to the terms of Section 2.1, the
Borrower may elect from time to time to convert all or any part of a Loan of any
Type into any other Type or Types of a Loan; provided that any conversion of any
Eurodollar  Loan  shall be made on,  and only on,  the last day of the  Interest
Period applicable thereto. The Borrowers shall give the Agent irrevocable notice
(a   "Conversion/Continuation   Notice")  of  each   conversion  of  a  Loan  or
continuation  of a Eurodollar  Loan not later than 10:00 a.m.  (Chicago time) at
least one Business  Day, in the case of a conversion  into a Floating Rate Loan,
or three Business Days, in the case of a conversion  into or  continuation  of a
Eurodollar Loan, prior to the date of the requested  conversion or continuation,
specifying:

               (i) the  requested  date,  which shall be a Business Day, of such
conversion or continuation,

               (ii) the  aggregate  amount  and Type of the Loan  which is to be
converted or continued, and

               (iii) the amount and  Type(s) of Loan(s)  into which such Loan is
to be  converted  or  continued  and,  in  the  case  of a  conversion  into  or
continuation  of  a  Eurodollar  Loan,  the  duration  of  the  Interest  Period
applicable thereto.

          (c)  Subject  to the  terms  and  conditions  of this  Agreement,  the
proceeds of such  requested  Loan shall be made  available  to the  Borrowers by
depositing the proceeds thereof, in immediately  available funds, on the Advance
Date for such Loan in an account  maintained  and designated by the Borrowers at
the principal  office of the Agent.  Each Bank, on the Advance Date of each such
Loan  shall  make  its Pro Rata  Share of such  Loan  available  in  immediately
available  funds at the principal  office of the Agent for  disbursement  to the
Borrowers.  Unless the Agent shall have  received  notice from any Bank prior to
the date of any  requested  Loan under this  Section 3.1 that such Bank will not
make  available  to the Agent such Bank's Pro Rata  Share,  the Agent may assume
that such Bank has made such share available to the Agent on the Advance Date of
such Loan in accordance with this Section 3.1(b). If and to the extent such Bank
shall not have so made such Pro Rata Share available to the Agent, the Agent may
(but shall not be obligated  to) make such amount  available to the Borrowers on
the relevant Advance Date, and such Bank agrees to pay to the Agent forthwith on
demand such amount  together with interest  thereon,  for each day from the date
such amount is made  available to the Borrowers by the Agent until the date such
amount is paid to the Agent,  at the Federal  Funds Rate. If such Bank shall pay
to the Agent such  amount,  such amount so paid shall  constitute a Loan by such
Bank as a part of such borrowing for purposes of this Agreement.  The failure of
any Bank to make its Pro Rata  Share of any such  Loan  available  to the  Agent



                                      E-70

<PAGE>



shall not relieve any other Bank of its  obligations  to make  available its Pro
Rata Share of such Loan on the Advance  Date of such Loan,  but no Bank shall be
responsible  for failure of any other Bank to make such Pro Rata Share available
to the Agent on the Advance Date of any such Loan.

          (d) Each Bank may book its Loans at any Lending Installation  selected
by such Bank and may  change its  Lending  Installation  from time to time.  All
terms of this  Agreement  shall apply to any such Lending  Installation  and the
Notes  shall  be  deemed  held by each  Bank  for the  benefit  of such  Lending
Installation.  Each Bank may,  by written  or telex  notice to the Agent and the
Borrowers,  designate a Lending Installation through which Loans will be made by
it and for whose account Loan payments are to be made.

          (e)  Nothing  in this  Agreement  shall be  construed  to  require  or
authorize any Bank to issue any Letter of Credit,  it being  recognized that the
Agent has the sole obligation under this Agreement to issue Letters of Credit on
behalf of the Banks, and the Commitment of each Lender with respect to Letter of
Credit Advances is expressly  conditioned  upon the Agent's  performance of such
obligations.  Upon such issuance by the Agent, each Bank shall automatically and
unconditionally  acquire a risk participation  interest to the extent of its Pro
Rata Share in such Letter of Credit Advance based on its respective  Commitment.
If the Agent shall honor a draft or other  demand for payment  presented or made
under any Letter of Credit,  the Agent shall provide notice thereof to each Bank
on the date such draft or demand is  honored  unless  the  Borrowers  shall have
satisfied  their  reimbursement  obligation  under Section 3.3 by payment to the
Agent on such date.  Each Bank,  not later than the Business Day after the Agent
shall have given the notice specified in the previous  sentence,  shall make its
Pro  Rata  Share  of the  amount  paid by the  Agent  available  in  immediately
available  funds at the  principal  office of the Agent for the  account  of the
Agent.  If and to the extent such Bank shall not have made any required Pro Rata
Share  amount  available  to the  Agent or made its  portion  of Loan  available
pursuant to Section  3.3(a)(i),  such Bank and the Borrowers  severally agree to
pay to the Agent forthwith on demand such amount together with interest thereon,
for each day from the date such  amount was paid by the Agent  until such amount
is so made  available to the Agent at (i) the interest  rate then  applicable to
Floating  Rate Loans for such day in the case of the Borrowers and (ii) the rate
per  annum  equal  to the  Federal  Funds  Rate for the  first  five  days,  and
thereafter at the interest rate  applicable to Floating Rate Loans,  in the case
of any Bank. If such Bank shall pay such amount to the Agent  together with such
interest,  such amount so paid shall  constitute  a Loan by such Bank as part of
the Loans disbursed in respect of the reimbursement  obligation of the Borrowers
under  Section 3.3 for  purposes of this  Agreement.  The failure of any Bank to
make its Pro Rata Share of any such  amount paid by the Agent  available  to the
Agent shall not relieve any other Bank of its  obligation to make  available its
Pro Rata Share of such amount,  but no Bank shall be responsible  for failure of
any other Bank to make such Pro Rata Share available to the Agent.

     3.2 Conditions of Advances.  The Banks and the Agent shall not be obligated
to make any Advance hereunder at any time unless:

          (a) On the Effective Date,  which may not be after May 14, 1999, there
shall have been  delivered  to each Bank the  following  documents,  in form and

               (v) the Consent and Amendment of Security Documents duly executed

               (vii) the  execution  by the  Borrowers  of the Agent's  standard

               (viii) the Banks shall have  determined that the Loans to be made
are equal to or less than the Borrowing Base;

Agreement,  (B) all Indenture Debt Documents and the Preferred  Stock  Documents
shall  have been  delivered  to the Agent and the Banks and shall be in form and

have been completed; and



                                      E-72

and  amendments  of  existing  Security  Documents,  all in form  and  substance
satisfactory to the Banks.

          (b) The aggregate  outstanding  principal amount of all Advances after
giving  effect  to the  proposed  Advance,  does not  exceed  the  lesser of the
Commitments or the Borrowing Base.

          (c) On and as of the date of each such  Advance,  the  representations
and  warranties  contained  in Section 6 hereof shall be true and correct in all
material respects as if made on such date; provided,  however, that for purposes
of this Section 3.2(c) the representations  and warranties  contained in Section
6.7 hereof  shall be deemed made with respect to both the  financial  statements
referred to therein and the most recent financial  statements delivered pursuant
to Section 7.1(d)(ii) and (iii).

          (d) No  Default or event or  condition  which  could  cause a Material
Adverse   Effect  has  occurred  and  is  continuing  or  will  exist  upon  the

deemed to be a  certification  by the Borrowers at such time with respect to the
matters set forth in subparagraphs (b), (c) and (d) of this Section 3.2.

     3.3 Letter of Credit Reimbursement Payments.  (a)(i) The Borrowers agree to
pay to the  Agent,  on the day on which the Agent  shall  honor a draft or other
demand for payment presented or made under any Letter of Credit, an amount equal
to the amount paid by the Agent in respect of such draft or other  demand  under
such Letter of Credit and all  expenses  paid or incurred by the Agent  relative
thereto.  Unless the Borrowers shall have made such payment to the Agent on such
day,  upon each such  payment  by the Agent,  the Agent  shall be deemed to have
disbursed to the Borrowers, and the Borrowers shall be deemed to have elected to
satisfy the  reimbursement  obligation by borrowing,  a Loan bearing interest at
the Floating  Rate for the account of the Banks in an amount equal to the amount
so paid by the Agent in respect of such draft or other  demand under such Letter
of Credit.  Such Loan shall be  disbursed,  and each Bank shall  advance its Pro
Rata Share  thereof,  notwithstanding  any failure to satisfy any conditions for
disbursement of any Loan set forth in Article III or any other condition and, to
the  extent  of the  Loan so  disbursed,  the  reimbursement  obligation  of the
Borrowers under this Section 3.3 shall be deemed satisfied;  provided,  however,
that  such  disbursement  shall  not be  deemed  to be a waiver  of any Event of
Default or Default, if any.

               (ii) If for any reason (including  without limitation as a result
of the occurrence of an Event of Default pursuant to Section  6.1(h)),  Floating
Rate Loans may not be made by the Banks as described in Section 3.3(a)(i),  then
(A) the Borrowers agree that each reimbursement  amount not paid pursuant to the
first sentence of Section  3.3(a)(i)  shall bear interest,  payable on demand by
the Agent, at the interest rate then applicable to Floating Rate Loans,  and (B)
effective on the date each such  Floating  Rate Loan would  otherwise  have been
made, each Bank severally agrees that it shall  unconditionally and irrevocably,
without regard to the occurrence of any Default or Event of Default,  in lieu of
a deemed  disbursement  of Loans,  to the extent of such  Bank's Pro Rata Share,
purchase a participating  interest in each reimbursement  amount. Each Bank will
immediately  transfer  to the  Agent,  in same  day  funds,  the  amount  of its
participation.  Each Bank  shall  share in  accordance  with its Pro Rata  Share
(calculated  by reference to the  Commitments)  in any  interest  which  accrues
thereon and in all repayments  thereof. If and to the extent that any Bank shall
not have so made the  amount of such  participating  interest  available  to the
Agent, such Bank and the Borrowers agree to pay to the Agent forthwith on demand
such amount together with interest thereon, for each day from the date of demand



                                      E-73

<PAGE>


by the Agent until the date such amount is paid to the Agent, at (x) in the case
of the Borrowers,  the interest rate then  applicable to Floating Rate Loans and
(y) in the case of such Bank,  the  Federal  Funds Rate for the first five days,
and thereafter the interest rate applicable to Floating Rate Loans.

          (b) The reimbursement  obligations of the Borrowers under this Section
3.3 shall be absolute,  unconditional  and  irrevocable and shall remain in full
force and effect  until all  obligations  of the  Borrowers to the Agent and the
Banks hereunder shall have been satisfied, and such obligations of the Borrowers
shall not be  affected,  modified or impaired  upon the  happening of any event,
including without limitation,  any of the following,  whether or not with notice
to, or the consent of, the Borrowers:

               (i) Any lack of  validity  or  enforceability  of any  Letter  of
Credit  or  any  documentation  relating  to  any  Letter  of  Credit  or to any
transaction  related in any way to such Letter of Credit (the  "Letter of Credit
Documents");

               (ii) Any  amendment,  modification,  waiver  or  consent,  or any
substitution,  exchange  or release of or failure  to perfect  any  interest  in
collateral or security, with respect to any of the Letter of Credit Documents.

               (iii) The existence of any claim, setoff,  defense or other right
which  the  Borrowers  may  have at any  time  against  any  beneficiary  or any
transferee of any Letter of Credit (or any persons or entities for whom any such
beneficiary or any such transferee may be acting),  the Agent or any Bank or any
other person or entity,  whether in connection  with any of the Letter of Credit
Documents,  the  transactions  contemplated  herein or therein or any  unrelated
transactions;

               (iv) Any draft or other statement or document presented under any
Letter of Credit proving to be forged,  fraudulent,  invalid or  insufficient in
any respect or any statement therein being untrue or inaccurate in any respect;

               (v) Payment by the Agent to the  beneficiary  under any Letter of
Credit against  presentation  of documents which do not comply with the terms of
the Letter of Credit,  including  failure of any documents to bear any reference
or adequate reference to such Letter of Credit;

               (vi)  Any  failure,  omission,  delay  or lack on the part of the
Agent or any Bank or any  party to any of the  Letter  of  Credit  Documents  to
enforce, assert or exercise any right, power or remedy conferred upon the Agent,
any Bank or any such party under this  Agreement  or any of the Letter of Credit
Documents,  or any other acts or omissions on the part of the Agent, any Bank or
any such party; or

               (vii) Any other event or circumstance  that would, in the absence
of this  clause,  result in the  release or  discharge  by  operation  of law or
otherwise the Borrowers from the  performance  or observance of any  obligation,
covenant or agreement  contained  in this Section 3.3. No setoff,  counterclaim,
reduction or diminution  of any  obligation or any defense of any kind or nature
which the Borrowers  have or may have against the  beneficiary  of any Letter of
Credit shall be available  hereunder to the  Borrowers  against the Agent or any
Bank.  Nothing in this  Section  3.3 shall limit the  liability,  if any, of the
Borrowers to the Banks pursuant to Section 10.5(b).

     3.4.  Withholding  Tax Exemption.  At least five Business Days prior to the
first date on which  interest or fees are payable  hereunder  for the account of
any Bank, each Bank that is not incorporated under the laws of the United States
of  America, or a  state thereof,  agrees that it  will deliver to  each  of the



                                      E-74

<PAGE>



Borrowers  and the Agent two duly  completed  copies of United  States  Internal
Revenue  Service Form 1001 or 4224,  certifying in either case that such Bank is
entitled  to  receive  payments  under  this  Agreement  and the  Notes  without
deduction or withholding  of any United States  federal income taxes.  Each Bank
which so delivers a Form 1001 or 4224 further  undertakes  to deliver to each of
the Borrowers and the Agent two  additional  copies of such form (or a successor
form) on or before the date that such form expires (currently,  three successive
calendar  years for Form 1001 and one  calendar  year for Form  4224) or becomes
obsolete  or after the  occurrence  of any event  requiring a change in the most
recent forms so delivered by it, and such  amendments  thereto or  extensions or
renewals  thereof as may be reasonably  requested by the Borrowers or the Agent,
in each case  certifying  that such Bank is entitled to receive  payments  under
this  Agreement and the Notes  without  deduction or  withholding  of any United
States federal income taxes,  unless an event (including  without limitation any
change in treaty, law or regulation) has occurred prior to the date on which any
such  delivery  would  otherwise  be  required  which  renders  all  such  forms
inapplicable  or  which  would  prevent  such  Bank  from  duly  completing  and
delivering  any such form with respect to it and such Bank advises the Borrowers
and the Agent that it is not capable of receiving payments without any deduction
or withholding of United States federal income tax.

     SECTION 4. Payment and Prepayment; Fees; Change in Circumstances.

     4.1 Principal Payments.

          (a) Unless  earlier  payment is  required  under this  Agreement,  the
Borrowers shall pay the entire  outstanding  principal amount of the Advances on
the Termination Date.

          (b) The Borrowers may from time to time prepay all or a portion of the
Advances without premium or penalty,  provided,  however, that (i) the Borrowers
shall have given not less than one Business  Day's prior written  notice thereof
to the Agent, (ii) other than mandatory payments,  each such prepayment,  in the
case of  prepayment of Floating  Rate Loans,  shall be in the minimum  amount of
$500,000 and in integral multiples of $100,000 and, in the case of prepayment of
Eurodollar  Loans,  shall be in the minimum amount of $1,000,000 and in integral
multiples  thereof,  (iii)  any  prepayment  of any  Eurodollar  Loan  shall  be
accompanied by any amount required pursuant to Section 4.10.

          (c) If it should be  determined by the Agent at any time and from time
to time that the principal  amount of the Advances exceed the lesser of the then
Borrowing Base or the Commitments (such condition defined herein as a "Borrowing
Base Deficiency"), the Borrowers shall within thirty (30) days of written notice
to the Borrowers of such  Borrowing  Base  Deficiency,  in addition to all other
payments of principal and interest  required to be paid on the Advances,  prepay
upon demand and without  premium or penalty the  Advances in an amount by which,
in the determination of the Agent, such aggregate  principal amount  outstanding
exceeds the lesser of the then Borrowing Base or the Commitments,  provided that
such  prepayment  shall be made  first on the Loans and if the Loans are paid in
full and such excess still exists,  the Borrowers  shall provide cash collateral
for any outstanding Letters of Credit to the extent of such remaining excess.

          (d) In addition to all other  payments  required  hereunder,  upon any
sale or other  disposition of any assets when a Default exists,  or if such sale
or other disposition would cause a Default or would cause a required  prepayment
of, or offer to purchase,  the Indenture  Notes,  the Borrowers shall prepay the
Advances by an amount equal to 100% of the net proceeds  (net only of reasonable
and  customary  costs  of  such  sale or  other  disposition)  of  such  sale or
disposition, which prepayment is due upon receipt of such net proceeds.

          (e) In addition to all other  payments  required  hereunder,  upon any
sale or other disposition of any assets when a Borrowing Base Deficiency exists,
or if such sale or other  disposition  would cause a Borrowing Base  Deficiency,
the  Borrower  shall  prepay the  Advances by the amount of the  Borrowing  Base
Deficiency from the net proceeds (net only of any reasonable and customary costs
of such sale or other disposition) of such sale or disposition, which prepayment
is due upon receipt of such net proceeds.

               Unless  specified as a determination to be made by all Banks, all
determinations  made  pursuant to this Section 4.1 shall be made by the Agent or
the Required Banks, as the case may be, and shall be conclusively binding on the
parties absent manifest error.

     4.2 Interest Payment.  (a) The Borrowers shall pay interest to the Banks on
the unpaid principal  amount of each Loan for the period  commencing on the date
such Loan is made until such Loan is paid in full, on each Interest Payment Date
and at maturity (whether at stated maturity, by acceleration or otherwise),  and
thereafter on demand,  at the following rates per annum: (i) during such periods
that such Loan is a Floating Rate Loan,  the Floating Rate, and (ii) during such
periods that such Loan is a Eurodollar  Loan, the Eurodollar  Rate applicable to
such Loan for each related Eurodollar Interest Period.

          (b)  Notwithstanding the foregoing paragraph (a), the Borrowers hereby
agree,  if  requested by the  Required  Banks,  to pay interest on demand at the
Overdue  Rate on the  outstanding  principal  amount  of any Loan and any  other
amount payable by the Borrowers  hereunder (other than interest) upon and during
the continuance of any Default.

     4.3 Fees.  (a) The  Borrowers  agree to pay to the Agent,  for the pro rata
account of the Banks in accordance with their Pro Rata Shares,  a commitment fee
computed at the per annum rate equal to the  Applicable  Margin on the amount by
which the Borrowing Base exceeds the aggregate  outstanding  principal amount of
the Advances for the period from the Effective Date until the Termination  Date.
Such fee shall be paid  quarterly  in arrears on the last  Business  Day of each
March, June, September and December and on the Termination Date.

          (b) The  Borrowers  agree (i) to pay to the Agent,  for the benefit of
the  Banks,  a fee  computed  at the  Applicable  Margin on the  maximum  amount
available  to be drawn under each Letter of Credit at the time such fee is to be
paid for the period  from and  including  the date of issuance of such Letter of
Credit to and  including  the stated  expiry date of such Letter of Credit,  and
(ii) to pay an additional  fee to the Agent for its own account  computed at the
rate of 0.25% per annum on such maximum amount for such period.  Such fees shall
be payable  each month in  advance,  payable on the date of the  issuance of any
Letter of Credit and each month thereafter.  Such fees are nonrefundable and the
Borrowers  shall not be entitled  to any rebate of any  portion  thereof if such
Letter of Credit  does not remain  outstanding  through  the date for which such
fees have been paid. The Borrowers further agree to pay to the Agent, on demand,
such other customary  administrative  fees, charges and expenses of the Agent in
respect  of the  issuance,  negotiation,  acceptance,  amendment,  transfer  and
payment  of  each  Letter  of  Credit  or  otherwise  payable  pursuant  to  the
application  and  related  documentation  under  which such  Letter of Credit is
issued.

          (c) The Borrowers agree to pay to the Agent,  for the pro rata benefit
of the Banks,  an upfront fee equal to 0.50% of the amount of the  Commitment of
each Bank, payable on the Effective Date.

          (d) The Borrowers  agree to pay to the Agent agency and servicing fees
for its  services  under this  Agreement  in such amounts as it may from time to
time be agreed upon  between  the  Borrowers  and the Agent,  which fee shall be
retained solely by the Agent.



                                      E-76

     4.4 Payment Method. All payments to be made by the Borrowers hereunder will
be made in  Dollars  and in  immediately  available  funds  to the  Agent at its
address set forth in Section 10.2 not later than 11:00 a.m.  Chicago time on the
date on which such payment shall become due.  Payments received after 11:00 a.m.
Chicago  time shall be deemed to be  payments  made prior to 11:00 a.m.  Chicago
time on the next  succeeding  Business  Day.  At the time of  making  each  such
payment,  the  Borrowers  shall  specify  to the Agent  that  obligation  of the
Borrowers  hereunder  to which such  payment is to be applied,  or, in the event
that the  Borrowers  fail to so  specify  or if an Event of  Default  shall have
occurred  and be  continuing,  the  Agent  may  apply  such  payments  as it may
determine in its sole  discretion.  On the day such payments are  received,  the
Agent  shall  remit  to the  Banks  their  respective  Pro Rata  Shares  of such
payments, in immediately available funds.

     4.5 No Setoff or  Deduction.  All  payments of principal of and interest on
the Advances and other amounts payable by the Borrowers  hereunder shall be made
by the  Borrowers  without  setoff or  counterclaim,  and free and clear of, and
without  deduction or  withholding  for, or on account of, any present or future
taxes, levies, imposts, duties, fees, assessments,  or other charges of whatever
nature, imposed by any governmental authority,  or by any department,  agency or
other political subdivision or taxing authority.


     4.6 Payment on Non-Business Day; Payment Computations.  Except as otherwise
provided  in  this  Agreement  to the  contrary,  whenever  any  installment  of
principal  of, or interest on, any Advances  outstanding  hereunder or any other
amount due  hereunder,  becomes due and payable on a day which is not a Business
Day, the maturity thereof shall be extended to the next succeeding  Business Day
and, in the case of any  installment  of  principal,  interest  shall be payable
thereon  at the rate per annum  determined  in  accordance  with this  Agreement
during such extension. Computations of interest and other amounts due under this
Agreement shall be made on the basis of a year of 360 days for the actual number
of days  elapsed,  including  the  first day but  excluding  the last day of the
relevant period.

     4.7. Yield Protection. If any law or any governmental or quasi-governmental
rule,  regulation,  policy,  guideline or  directive  (whether or not having the
force of law),  or any  interpretation  thereof,  or the  compliance of any Bank
therewith,

               (i) subjects any Bank or any applicable  Lending  Installation to
any tax, duty,  charge or withholding on or from payments due from the Borrowers
(excluding  federal taxation of the overall net income of any Bank or applicable
Lending Installation),  or changes the basis of taxation of payments to any Bank
in respect of its Loans or other amounts due it hereunder, or

               (ii)  imposes  or  increases  or deems  applicable  any  reserve,
assessment,  insurance charge,  special deposit or similar  requirement  against
assets of,  deposits with or for the account of, or credit extended by, any Bank
or any  applicable  Lending  Installation  (other than reserves and  assessments
taken into account in  determining  the interest  rate  applicable to Eurodollar
Loans), or

               (iii)  imposes  any  other  condition  the  result of which is to
increase the cost to any Bank or any applicable Lending  Installation of making,
funding or maintaining loans or reduces any amount receivable by any Bank or any
applicable  Lending  Installation in connection with loans, or requires any Bank
or any  applicable  Lending  Installation  to make  any  payment  calculated  by
reference  to the amount of loans held or interest  received by it, by an amount



                                      E-77

<PAGE>


deemed material by such Bank,  then,  within 30 days of demand by such Bank, the
Borrowers shall pay such Bank that portion of such increased expense incurred or
reduction in an amount  received which such Bank  determines is  attributable to
making, funding and maintaining its Loans and its Commitment.

     4.8.  Changes in Capital  Adequacy  Regulations.  If a Bank  determines the
amount of capital  required  or  expected  to be  maintained  by such Bank,  any
Lending  Installation of such Bank or any corporation  controlling  such Bank is
increased as a result of a Change,  then, within 15 days of demand by such Bank,
the Borrowers  shall pay such Bank the amount  necessary to  compensate  for any
shortfall in the rate of return on the portion of such  increased  capital which
such Bank  determines is  attributable  to this  Agreement,  its Advances or its
Commitment  (after  taking  into  account  such  Bank's  policies  as to capital
adequacy). "Change" means (i) any change after the date of this Agreement in the
Risk-Based  Capital  Guidelines  or (ii) any  adoption of or change in any other
law, governmental or quasi-governmental  rule,  regulation,  policy,  guideline,
interpretation,  or directive (whether or not having the force of law) after the
date of this Agreement which affects the amount of capital  required or expected
to be  maintained  by any Bank or any Lending  Installation  or any  corporation
controlling any Bank.  "Risk-Based  Capital Guidelines" means (i) the risk-based
capital guidelines in effect in the United States on the date of this Agreement,
including  transition  rules,  and (ii) the  corresponding  capital  regulations
promulgated by regulatory authorities outside the United States implementing the
July 1988 report of the Basle  Committee on Banking  Regulation and  Supervisory
Practices  Entitled  "International  Convergence  of  Capital  Measurements  and
Capital  Standards,"  including  transition  rules,  and any  amendments to such
regulations adopted prior to the date of this Agreement.

     4.9.  Availability  of  Types of  Advances.  If any  Bank  determines  that
maintenance of its Eurodollar  Loans at a suitable  Lending  Installation  would
violate any  applicable  law,  rule,  regulation,  or directive,  whether or not
having the force of law, or if the Required Banks determine that (i) deposits of
a type and maturity appropriate to match fund Eurodollar Loans are not available
or (ii) the interest rate  applicable  to a Type of Advance does not  accurately
reflect the cost of making or  maintaining  such  Advance,  then the Agent shall
suspend  the  availability  of the  affected  Type of Advance  and  require  any
Eurodollar Loans of the affected Type to be repaid.

     4.10. Funding  Indemnification.  If any payment of a Eurodollar Loan occurs
on a date which is not the last day of the applicable  Interest Period,  whether
because of  acceleration,  prepayment or otherwise,  or a Eurodollar Loan is not
made on the date specified by the Borrowers for any reason other than default by
the Banks,  the Borrowers will indemnify each Bank for any loss or cost incurred
by it resulting therefrom,  including,  without limitation,  any loss or cost in
liquidating  or employing  deposits  acquired to fund or maintain the Eurodollar
Loan.

     4.11.  Bank  Statements;  Survival of Indemnity.  To the extent  reasonably
possible,  each Bank shall  designate an  alternate  Lending  Installation  with
respect to its Eurodollar Loans to reduce any liability of the Borrowers to such
Bank  under  Sections  4.7 and 4.8 or to avoid the  unavailability  of a Type of
Advance under Section 4.9, so long as such designation is not disadvantageous to
such  Bank.  Each Bank  shall  deliver a written  statement  of such Bank to the
Borrowers  (with  a copy to the  Agent)  as to the  amount  due,  if any,  under
Sections 4.7, 4.8 or 4.10. Such written  statement shall set forth in reasonable
detail the calculations upon which such Bank determined such amount and shall be
final, conclusive and binding on the Borrowers in the absence of manifest error.
Determination  of amounts  payable  under such  Sections  in  connection  with a
Eurodollar  Loan shall be calculated  as though each Bank funded its  Eurodollar
Loan through the purchase of a deposit of the type and maturity corresponding to
the deposit used as a reference in determining the Eurodollar Rate applicable to
such Loan,  whether in fact that is the case or not. Unless  otherwise  provided
herein,  the amount  specified  in the  written  statement  of any Bank shall be



                                      E-78

<PAGE>



payable on demand after receipt by the Borrowers of such written statement.  The
obligations  of the  Borrowers  under  Sections  4.7, 4.8 and 4.10 shall survive
payment of the Bank Obligations and termination of this Agreement.

     SECTION 5. Security

     5.1  Security  Documents.  To  secure  all  indebtedness,  obligations  and
liabilities  under  this  Agreement,  the Notes,  the  Security  Documents,  the
Advances,  any Swap  Agreements  among any Borrower and any Lender and to secure

Banks pursuant thereto, whether direct or indirect,  absolute or contingent, due

previously  executed and delivered in favor of the Agent or any Bank (as amended
or modified from time to time,  the  "Mortgages"  and together with the Security
Agreements, and all agreements and documents described in this Section 5.1(a) or
in 5.1(b) or 5.2 and all other agreements and documents securing any of the Bank
Obligations  at any time or otherwise  executed by any Borrower with or in favor
of the Agent and the  Banks,  and  including  without  limitation  the Letter of
Credit  Documents,  as  amended or  modified  from time to time,  the  "Security
Documents"),  in form and substance satisfactory to the Required Banks, granting
the Agent,  for the  benefit  of the  Banks,  a  first-priority,  perfected  and
enforceable lien and security interest,  subject only to the Permitted Liens, in
the following (collectively,  with all other assets described in Section 5.1(b),
the  "Collateral"):  all oil, gas and mineral properties and all other assets of
the Borrowers as requested at any time by the Required Banks,  including without
limitation  all  leasehold  and  royalty  interests  and  all  other  rights  in
connection  therewith,  and all  interests in machinery,  equipment,  materials,
improvements,  hereditaments,  appurtenances and other property,  real, Personal
and/or  mixed,  now or hereafter a part of or obtained in or used in  connection
with such  properties and all interests in and to any and all oil, gas and other
minerals now in storage or now or hereafter  located in,  under,  on or produced
from,  such  properties and an assignment of production  from such properties to
the Agent;

          (b) Execute and deliver to the Agent, on or before the Effective Date,
such security  agreements,  pledge  agreements,  financing  statements and other
agreements,  including without  limitation the Consent and Amendment of Security
Documents   confirming  the  continuing   effectiveness  of  Security  Documents
previously  executed  and  delivered  to the  Agent or any Bank (as  amended  or
modified from time to time,  the "Security  Agreements"),  in form and substance
satisfactory  to the Required Banks,  granting to the Agent,  for the benefit of
the  Banks,  a  first-priority,  perfected  and  enforceable  lien and  security
interest,  subject only to the Permitted  Liens,  in all other  assets,  whether
real,  personal  or mixed,  and  whether  now owned or  hereafter  existing  and
wherever located, of the Borrowers.

     5.2 Additional Security Documents. If at any time requested by the Agent or
the Required  Banks,  the Borrowers  shall  execute and deliver such  additional
documents,  and shall take such other action, as the Agent or the Required Banks
may reasonably consider necessary or proper to evidence or perfect the liens and
security interests described in Section 5.1 hereof.



                                      E-79

     SECTION 6. Representations and Warranties.

     Each of the Borrowers represents and warrants that:

     6.1 Corporate  Existence and Power.  It is a  corporation  duly  organized,
validly  existing and in good standing under the laws of the jurisdiction of its
incorporation, and is duly qualified to do business and in good standing in each
additional  jurisdiction  where  failure  to so  qualify  would  have a Material
Adverse Effect.  It has all requisite  corporate power to own its properties and
to carry on its business as now being conducted and as proposed to be conducted,
and to execute and deliver this Agreement,  the Notes and the Security Documents
and to engage in the transactions  contemplated by this Agreement, the Notes and
the Security Documents.

     6.2 Corporate Authority.  The execution,  delivery and performance by it of
this  Agreement,  the Notes and the Security  Documents are within its corporate
powers,  have been duly authorized by all necessary corporate action and are not
in contravention of any law, rule or regulation, or any judgment,  decree, writ,
injunction,  order or award of any arbitrator,  court or governmental authority,
or of the terms of its charter or by-laws,  or of any contract or undertaking to
which it is a party or by which it or its property may be bound or affected.

     6.3  Binding  Effect.  This  Agreement  is, and the Notes and the  Security
Documents to which it is a party when delivered  hereunder will be, legal, valid
and binding obligations of each Borrower, enforceable against each in accordance
with their respective terms.

     6.4  Subsidiaries.  All  Subsidiaries  of CRI are duly  organized,  validly
existing  and in  good  standing  under  the  laws  of  their  jurisdictions  of
organization  and are duly qualified to do business in each  jurisdiction  where
failure to so qualify  would have a Material  Adverse  Effect.  All  outstanding
shares of Capital  Stock of each class of each  Subsidiary  of CRI have been and
will be validly issued and are and will be fully paid and  nonassessable and are
and will be owned,  beneficially  and of record,  by CRI,  free and clear of any
Liens.  Schedule 6.4 is a complete list of all  Subsidiaries  of CRI. COG is and
will  remain  a wholly  owned  subsidiary  of CRI and COGL is and will  remain a
wholly owned  subsidiary  of COG, and Offshore is and will remain a wholly owned
subsidiary of COGL.

     6.5 Liens.  The  properties  of each  Borrower and each  Subsidiary  of any
Borrower  (including  without  limitation the Collateral) are not subject to any
Lien except Permitted Liens.

     6.6 Litigation.  There is no action,  suit or proceeding pending or, to the
best of its  knowledge,  threatened  against  or  affecting  it before or by any
court, governmental authority, or arbitrator which would be reasonably likely to
result in, either  individually or collectively,  a Material Adverse Effect and,
to the best of the Borrowers' knowledge,  there is no basis for any such action,
suit or proceeding.

     6.7  Financial  Condition.  The  consolidated  balance sheet of CRI and its
Subsidiaries and the consolidated  statements of income and cash flow of CRI and
its  Subsidiaries for the fiscal year ended December 31, 1998 and reported on by
Arthur Andersen,  LLP, copies of which have been furnished to the Banks,  fairly
present,  and  the  financial  statements  of CRI  and  its  Subsidiaries  to be
delivered  pursuant  to Section  7.1(d) will fairly  present,  the  consolidated
financial  position  of CRI  and its  Subsidiaries  as of the  respective  dates
thereof,  and the consolidated results of operations of CRI and its Subsidiaries
for the respective periods indicated,  all in accordance with generally accepted
accounting  principles   consistently  applied.  There  has  been  no  event  or



                                      E-80

<PAGE>



development  which  has had or would be  reasonably  likely  to have a  Material
Adverse  Effect  since  December  31,  1998.  There  is no  material  Contingent
Liability  of CRI or any of its  Subsidiaries  that  is not  reflected  in  such
financial statements or in the notes thereto.

     6.8 Use of  Advances.  The  Advances  will be used for working  capital and
general corporate  purposes.  No Borrower extends or maintains,  in the ordinary
course of business,  credit for the purpose, whether immediate,  incidental,  or
ultimate, of buying or carrying margin stock (within the meaning of Regulation U
of the Board of Governors  of the Federal  Reserve  System),  and no part of the
proceeds  of each  Advance  will be used  for the  purpose,  whether  immediate,
incidental,  or  ultimate,  of  buying  or  carrying  any such  margin  stock or
maintaining or extending  credit to others for such purpose.  After applying the
proceeds of the Advances, such margin stock will not constitute more than 25% of
the value of the assets that are subject to any  provisions of this Agreement or
any Security  Document  that may cause the  Advances to be secured,  directly or
indirectly by margin stock.

     6.9  Security  Documents.   The  Security  Documents  create  a  valid  and
enforceable first-priority lien on and perfected security interest in all right,
title and interest of each Borrower in and to the Collateral  described therein,
securing  all  amounts  intended  to  be  secured  thereby   (including  without
limitation  all  principal  of and  interest on the Notes)  subject  only to the
Permitted Liens. The respective net revenue interests of each Borrower in and to
the Oil and Gas  Interests as set forth in the Security  Documents  are true and
correct and  accurately  reflect the interests to which each Borrower is legally
entitled, subject only to the Permitted Liens.

     6.10  Consents,   Etc.  No  consent,   approval  or   authorization  of  or
declaration,  registration  or filing  with any  governmental  authority  or any
nongovernmental  Person or entity,  including without limitation any creditor or
stockholder  of it,  is  required  on the  part  of it in  connection  with  the
execution,  delivery and performance of this Agreement,  the Notes, the Security
Documents  or the  transactions  contemplated  hereby or as a  condition  to the
legality,  validity or enforceability of this Agreement, the Notes or any of the
Security Documents.

     6.11  Taxes.  It has  filed all tax  returns  (federal,  state  and  local)
required to be filed and has paid all taxes shown  thereon to be due,  including
interest and penalties,  or has established  adequate  financial reserves on its
books and records for payment  thereof,  except where the failure to do so would
not have a Material Adverse Effect.

     6.12 Title to Properties.  It has good and defensible title to, and a valid
indefeasible ownership interest in, all of its properties and assets (including,
without  limitation,  the Collateral subject to the Security Documents) free and
clear of any Lien  except the  Permitted  Liens,  and it is the owner of all the
Collateral described in the Security Documents to which it is a party. All wells
on any of the mortgaged premises have been drilled, operated, shut-in, abandoned
or  suspended  in  accordance  with  good  oil and gas  field  practices  and in
compliance with all applicable laws, permits,  statutes, orders, licenses, rules
and  regulations.  All leases with respect to any Oil and Gas Interests owned by
any  Borrower  are in good  standing  and  are in full  force  and  effect,  all
royalties,  rents,  taxes,  assessments  and other  payments  thereunder or with
respect thereto have been properly and timely paid and all conditions  necessary
to keep such leases in full force have been fully performed,  including  without
limitation  any condition to maintain  continuous  production or other  activity
with respect  thereto.  The Borrowers have delivered to the Agent title opinions
satisfactory  to the Agent and the Agent's  counsel with respect to at least 80%
of the value of the assets included in the Borrowing Base.

     6.13 ERISA.  CRI and its  Subsidiaries and their Plans are in compliance in
all material  respects with those  provisions of ERISA and of the Code which are



                                      E-81

<PAGE>



applicable  with respect to any Plan. No prohibited  transaction  (as defined in
Section 406 of ERISA and Section 9975 of the Code) and no  reportable  event (as
defined in ERISA) has occurred with respect to any Plan. Neither CRI, any of its
Subsidiaries  nor any of its ERISA Affiliates is an employer with respect to any
multiemployer  plan (as  defined  in Section  4001(a)(3)  of  ERISA).  CRI,  its
Subsidiaries and the ERISA Affiliates have met the minimum funding  requirements
under ERISA and the Code with respect to each of the respective  Plans,  if any,
and  have not  incurred  any  liability  to the  PBGC or any  Plan.  There is no
unfunded benefit liability with respect to any Plan.

     6.14 Environmental and Safety Matters.  It is in compliance in all material
respects  with all federal,  state and local laws,  ordinances  and  regulations
relating to safety and  industrial  hygiene or to the  environmental  condition,
including without limitation all Environmental Laws in jurisdictions in which it
owns any  interest in or operates,  a well, a facility or site,  or arranges for
disposal or treatment of hazardous  substances,  solid waste,  or other  wastes,
accepts for transporting any hazardous substances, solid waste, or other wastes,
or holds any  interest in real  property  or  otherwise,  except  where any such
noncompliance  would not have a  Material  Adverse  Effect.  No  demand,  claim,
notice, suit, suit in equity, action,  administrative  action,  investigation or
inquiry whether brought by any governmental authority,  private Person or entity
or otherwise, arising under, relating to or in connection with any Environmental
Laws is pending or, to the best of any Borrower's knowledge,  threatened against
it, any real  property  in which it holds or has held an interest or any past or
present  operation  of  it.  It (a)  does  not  know  of any  federal  or  state
investigation  evaluating  whether any remedial action is needed to respond to a
release of any toxic  substances,  radioactive  materials,  hazardous  wastes or
related  materials into the environment,  (b) has not received any notice of any
toxic substances,  radioactive  materials,  hazardous waste or related materials
in, or upon any of its  properties in violation of any  Environmental  Laws, and
(c) does not know of any basis for any such investigation,  notice or violation.
No material release,  threatened  release or disposal of hazardous waste,  solid
waste or other  wastes is  occurring  or has  occurred  on, under or to any real
property in which it holds any  interest or performs any of its  operations,  in
violation of any Environmental Law which would have a Material Adverse Effect.

     6.15 Direct  Benefit.  The initial  Advances  hereunder and all  additional
Advances are for the direct  benefit of each of the  Borrowers,  and the initial
Advances  hereunder  are  used to  refinance  and  replace  indebtedness  owing,
directly or indirectly,  by the Borrowers to the Banks under the Existing Credit
Agreement.  The Borrowers are engaged as an integrated  group in the business of
oil and gas exploration and related fields,  and any benefits to any Borrower is
a  benefit  to all  of  them,  both  directly  or  indirectly,  inasmuch  as the
successful  operation  and  condition of the  Borrowers  is  dependent  upon the
continued  successful  performance of the functions of the integrated group as a
whole.

     6.16  Solvency.  Each of the  following  is true for each  Borrower and the
Borrowers on a consolidated  basis:  (a) the fair saleable value of its property
is (i) greater than the total amount of its  liabilities  (including  contingent
liabilities), and (ii) greater than the amount that would be required to pay its
probable aggregate  liability on its then existing debts as they become absolute
and matured; (b) its property is not unreasonable in relation to its business or
any contemplated or undertaken transaction; and (c) it does not intend to incur,
or believe  that it will  incur,  debts  beyond its ability to pay such debts as
they become due.

     6.17  Disclosure.  This  Agreement and all other  documents,  certificates,
reports or statements or other information furnished to any Bank or the Agent in
writing by or on behalf of any Borrower in connection  with the  negotiation  or
administration  of this Agreement or any transactions  contemplated  hereby when
read together do not contain any untrue  statement of a material fact or omit to
state a material fact necessary in order to make the statements contained herein
and therein not  misleading.  There is no fact known to any  Borrower  which has



                                      E-82

<PAGE>



caused,  or which likely would in the future in the  reasonable  judgment of the
Borrowers cause, a Material  Adverse Effect (except for any economic  conditions
which  affect   generally   the  industry  in  which  the  Borrowers  and  their
Subsidiaries  conduct business),  which has not been set forth in this Agreement
or  in  the  other  documents,  certificates,   statements,  reports  and  other
information furnished in writing to the Banks by or on behalf of any Borrower in
connection with the transactions contemplated hereby.

     6.18  Indenture  Debt  Documents  and  Preferred   Stock   Documents.   All
representations  and warranties of the Borrowers contained in any Indenture Debt
Document  or  Preferred  Stock  Document  are true and  correct in all  material
respects.  CRI has issued  the  Indenture  Notes in the face  amount of at least
$150,000,000  on or prior to the Effective Date and all Indenture Debt Documents
have been delivered to the Agent and the Banks prior to the Effective  Date. CRI
has issued the Preferred  Stock in the amount of  $30,000,000 on or prior to the
Effective  Date and all Preferred  Stock  Documents  have been  delivered to the
Agent and the Banks prior to the Effective Date. There is no event of default or
event or  condition  which could become an event of default with notice or lapse
of time or both, under the Indenture Debt Documents or Preferred Stock Documents
and each of the Indenture Debt Documents and the Preferred Stock Documents is in
full force and effect.

     6.19 Year 2000. The Borrowers  have made a full and complete  assessment of
the Year 2000 Issues. Based on such assessment,  the Borrowers do not reasonably
anticipate that Year 2000 Issues will have a Material Adverse Effect.

of interest rates, exchange rates or commodity prices) for purposes of financial
speculation  or  otherwise  not  in  the  ordinary  course  of  business  of the
Borrowers, and any Swap Agreement with respect to fluctuations in interest rates
shall be entered into by the  Borrowers  only with respect to  Indebtedness  for
borrowed money of the Borrowers.

          (n) Payments and  Modification of Indenture Debt.  Make, or permit any
Subsidiary  to make,  any  optional  payment,  defeasance  (whether  a  covenant
defeasance,  legal defeasance or other defeasance),  prepayment or redemption of

grace provided with respect thereto,  which  individually or together with other
such  Indebtedness  as to  which  any  such  failure  exists  has  an  aggregate
outstanding principal amount in excess of $10,000,000;  or if any Borrower fails
to perform or observe any other term,  covenant or  agreement  contained  in any
agreement,  document or instrument evidencing or securing any such Indebtedness,
or under which any such Indebtedness was issued or created, beyond any period of
grace,  if any,  provided with respect  thereto if the effect of such failure is
either (i) to cause, or permit the holders of such Indebtedness (or a trustee on
behalf of such holders) to cause, any payment in respect of such Indebtedness to
become  due  prior  to its  due  date  or (ii) to  permit  the  holders  of such
Indebtedness  (or a trustee on behalf of such holder) to elect a majority of the

partial   withdrawal   under   ERISA   from  any   Multiemployer   Plan  or  the
reorganization,  insolvency,  or termination of any  Multiemployer  Plan, and in
each of the foregoing  cases,  such event or condition,  together with all other
events or  conditions,  if any,  could in the  opinion of the Banks  subject any
Borrower  to any tax,  penalty,  or other  liability  to a Plan,  the  PBGC,  or

faith by appropriate  proceedings,  such proceedings shall remain undismissed or



                                      E-90

<PAGE>



unstayed  for a period  of 30  days;  or any  Borrower  shall  take  any  action
(corporate or other) to authorize or further any of the actions  described above
in this subsection; or

          (h) Any event of default described in any Security Document shall have
occurred and be continuing,  or any material  provision of any Security Document
shall at any time for any reason  cease to be valid and binding and  enforceable
against  any  obligor   thereunder,   or  the   validity,   binding   effect  or
enforceability  thereof shall be contested or  repudiated by any Person,  or any
obligor,  shall  deny  that  it  has  any or  further  liability  or  obligation
thereunder,  or any Security  Document shall be  terminated,  invalidated or set
aside, or be declared  ineffective or inoperative or in any way cease to give or

          (j) or the occurrence of any "Change of Control",  "Change in Control"

     8.2 Remedies.

          (a) Upon the  occurrence  and during the  continuance  of any Event of
Default,  the Agent may, and upon being directed to do so by the Required Banks,
shall,  by notice to the  Borrowers  terminate  the  Commitments  or declare the
outstanding  principal  of,  and  accrued  interest  on, the Notes and all other
amounts due under this Agreement and all other Loan Documents, to be immediately
due and  payable,  or demand  immediate  delivery  of cash  collateral,  and the
Borrowers agree to deliver such cash  collateral upon such demand,  in an amount
equal to the maximum  amount that may be available to be drawn at any time prior
to the stated expiry of all outstanding  Letters of Credit, or all of the above,
whereupon the Commitments  shall terminate  forthwith and all such amounts shall
become  immediately due and payable,  or both, as the case may be, provided that
in the  case  of any  event  or  condition  described  in  Section  8.1(g),  the
Commitments shall  automatically  terminate forthwith and all such amounts shall
automatically  become  immediately due and payable without notice;  in each case
without demand,  presentment,  protest,  diligence,  notice of dishonor or other
formality, all of which are hereby expressly waived.

          (b) Upon the  occurrence  and during the  continuance of such Event of
Default,  the Agent may, and upon being directed to do so by the Required Banks,
shall,  in addition to the  remedies  provided  in Section  8.2(a),  enforce its
rights  either by suit in equity,  or by action at law, or by other  appropriate
proceedings,  whether for the specific  performance (to the extent  permitted by
law) of any  covenant or agreement  contained  in this  Agreement or in any then
outstanding Note or any Security Document or in aid of the exercise of any power
granted in this Agreement,  any then outstanding Notes or any Security Document,
and may enforce the payment of any then  outstanding  Notes and any of the other
rights of the Agent and the Banks in any other  agreement or available at law or
in equity.

          (c) Upon the  occurrence  and during the  continuance  of any Event of
Default  hereunder,  each  Bank may at any time and from  time to time,  without
notice to the Borrowers (any  requirement for such notice being expressly waived
by the  Borrowers)  set off and apply against any and all of the  obligations of
any Borrower now or hereafter existing under this Agreement, any of the Notes or
the  Security  Documents,  any and all  deposits  (general or  special,  time or
demand,  provisional  or final) at any time held and other  indebtedness  at any
time owing by such Bank to or for the credit or the account of any  Borrower and
any  property  of any  Borrower  from time to time in  possession  of such Bank,
irrespective of whether or not any Bank shall have made any demand hereunder and



                                      E-91

<PAGE>



although such  obligations  may be contingent and  unmatured.  The rights of the
Banks under this  Section  8.2(c) are in addition to other  rights and  remedies
(including,  without  limitation,  other  rights of setoff)  which the Banks may
have.

     8.3  Distribution  of  Proceeds.  All  proceeds of any  realization  on the
Collateral  received by the Agent  pursuant  to the  Security  Documents  or any
payments on any of the liabilities secured by the Security Documents received by
the Agent or any Bank upon and  during the  continuance  of any Event of Default
shall be allocated and distributed as follows:

          (a) First, to the payment of all costs and expenses, including without
limitation all attorneys'  fees, of the Agent in connection with the enforcement
of the Security Documents and otherwise administering this Agreement;

          (b) Second, to the payment of all costs,  expenses and fees, including
without  limitation,  commitment  fees and attorneys'  fees,  owing to the Banks
pursuant to the Bank Obligations on a pro rata basis in accordance with the Bank
Obligations  consisting of fees, costs and expenses owing to the Banks under the
Bank Obligations for application to payment of such liabilities;

          (c)  Third,  to the Banks on a pro rata basis in  accordance  with the
Bank  Obligations  consisting of interest and principal owing to the Banks under
the Bank  Obligations,  with any  obligations  owing to any Bank pursuant to any
Swap Agreement to which it is a party (whether pursuant to a termination thereof
or otherwise) and with any reimbursement  obligations or other liabilities owing
to any Bank pursuant to any Letter of Credit, for application to payment of such
liabilities;

          (c) Fourth,  to the payment of any and all other  amounts owing to the
Banks  on a pro  rata  basis  in  accordance  with  the  total  amount  of  such
Indebtedness  owing to each of the  Banks,  for  application  to payment of such
liabilities; and

          (d) Fifth,  to the  Borrowers  or such other  Person as may be legally
entitled thereto.

     8.4  Letter  of  Credit  Liabilities.  For the  purposes  of  payments  and
distributions  under Section 8.3, the full amount of Bank Obligations on account
of any Letter of Credit then  outstanding  but not drawn upon shall be deemed to
be then due and owing.  Amounts  distributable to any of the Banks on account of
such Bank  Obligations  under  such  Letter of Credit  shall be  deposited  in a
separate  interest  bearing  collateral  account  in the name of and  under  the
control of the Agent and held by the Agent first as security  for such Letter of
Credit Bank  Obligations and then as security for all other Bank Obligations and
the  amount  so  deposited  shall  be  applied  to the  Letter  of  Credit  Bank
Obligations  at such times and to the  extent  that such  Letter of Credit  Bank
Obligations become absolute liabilities. If and to the extent that the Letter of
Credit Bank Obligations fail to become absolute Bank Obligations  because of the
expiration or  termination  of the  underlying  Letters of Credit  without being
drawn upon, then such amounts shall be applied to the remaining Bank Obligations
in the order provided in Section 8.3. Each Borrower  hereby grants to the Agent,
for the  benefit of the Banks,  a lien and  security  interest in all such funds
deposited in such separate interest bearing collateral  account, as security for
all the Bank Obligations as set forth above. The Borrowers acknowledge and agree
that all  reimbursement  and other  obligations and liabilities  pursuant to any
Letters  of  Credit  issued by the Agent for the  account  of any  Borrower  are
secured by all Collateral and the Security Documents.

     SECTION 9. The Administrative Agent, the Syndication Agent and the Banks.

     9.1 Appointment; Nature of Relationship. The First National Bank of Chicago
is hereby appointed by the Banks as the administrative agent hereunder and under
each other Loan Document, and each of the Banks irrevocably authorizes the Agent
to act as the contractual representative of such Bank with the rights and duties
expressly set forth herein and in the other Loan Documents.  The Agent agrees to
act as such contractual  representative upon the express conditions contained in
this  Section 9.  Notwithstanding  the use of the  defined  term  "Agent," it is
expressly  understood  and agreed  that the Agent  shall not have any  fiduciary
responsibilities  to any Bank by reason  of this  Agreement  or any  other  Loan
Document and that the Agent is merely acting as the  representative of the Banks
with only those  duties as are  expressly  set forth in this  Agreement  and the
other Loan Documents. In its capacity as the Banks' contractual  representative,
the Agent (i) does not hereby assume any  fiduciary  duties to any of the Banks,
(ii) is a  "representative"  of the Banks within the meaning of Section 9-105 of
the Uniform  Commercial  Code and (iii) is acting as an independent  contractor,
the rights and duties of which are limited to those  expressly set forth in this
Agreement  and the other  Loan  Documents.  Each of the Banks  hereby  agrees to
assert no claim  against the Agent on any agency  theory or any other  theory of
liability  for breach of  fiduciary  duty,  all of which claims each Bank hereby
waives.

     9.2 Powers.  The Agent shall have and may  exercise  such powers  under the
Loan Documents as are  specifically  delegated to the Agent by the terms of each
thereof,  together with such powers as are reasonably  incidental  thereto.  The
Agent shall have no implied duties to the Banks,  or any obligation to the Banks
to take any action  thereunder  except any action  specifically  provided by the
Loan Documents to be taken by the Agent.

     9.3 General Immunity. Neither the Agent nor any of its directors, officers,
agents or employees shall be liable to the Borrowers, any Borrower, the Banks or
any Bank for any action taken or omitted to be taken by it or them  hereunder or
under any other Loan Document or in connection  herewith or therewith except for
its or their own gross negligence or willful misconduct.

     9.4 No Responsibility for Loans,  Recitals,  etc. Neither the Agent nor any
of its directors, officers, agents or employees shall be responsible for or have
any duty to ascertain,  inquire into, or verify (i) any  statement,  warranty or
representation  made in  connection  with any  Loan  Document  or any  borrowing
hereunder;  (ii)  the  performance  or  observance  of any of the  covenants  or
agreements  of  any  obligor  under  any  Loan  Document,   including,   without
limitation,  any agreement by an obligor to furnish information directly to each
Bank;  (iii) the  satisfaction  of any  condition  specified  in Section  3.2 or
otherwise   hereunder;   (iv)  the  validity,   enforceability,   effectiveness,
sufficiency  or  genuineness  of any Loan  Document or any other  instrument  or
writing  furnished  in  connection  therewith;  or (v) the  value,  sufficiency,
creation, perfection or priority of any interest in any collateral security. The
Agent  shall  have no duty to  disclose  to the  Banks  information  that is not
required to be  furnished  by the  Borrowers  to the Agent at such time,  but is
voluntarily  furnished by the  Borrowers to the Agent (either in its capacity as
Agent or in its individual capacity).

     9.5 Action on Instructions of Banks.  The Agent shall in all cases be fully
protected in acting, or in refraining from acting, hereunder and under any other
Loan Document in  accordance  with written  instructions  signed by the Required
Banks,  and such  instructions  and any action  taken or failure to act pursuant
thereto  shall be binding on all of the Banks and on all  holders of Notes.  The
Banks  hereby  acknowledge  that  the  Agent  shall be under no duty to take any
discretionary  action  permitted to be taken by it pursuant to the provisions of
this  Agreement  or any other  Loan  Document  unless it shall be  requested  in
writing to do so by the Required  Banks.  The Agent shall be fully  justified in
failing  or  refusing  to take any  action  hereunder  and under any other  Loan



                                      E-93

<PAGE>


Document  unless it shall first be indemnified to its  satisfaction by the Banks
pro rata  against any and all  liability,  cost and expense that it may incur by
reason of taking or continuing to take any such action.

     9.6  Employment  of Agents and  Counsel.  The Agent may  execute any of its
duties  as Agent  hereunder  and under any other  Loan  Document  by or  through
employees,  agents,  and  attorneys-in-fact  and shall not be  answerable to the
Banks, except as to money or securities received by it or its authorized agents,
for the default or misconduct of any such agents or  attorneys-in-fact  selected
by it with  reasonable  care.  The Agent  shall be entitled to advice of counsel
concerning  all matters  pertaining to the agency hereby  created and its duties
hereunder and under any other Loan Document.

     9.7  Reliance on  Documents;  Counsel.  The Agent shall be entitled to rely
upon any  Note,  notice,  consent,  certificate,  affidavit,  letter,  telegram,
statement,  paper or  document  believed  by it to be genuine and correct and to
have been  signed or sent by the proper  Person or  Persons,  and, in respect to
legal matters,  upon the opinion of counsel selected by the Agent, which counsel
may be employees of the Agent.

     9.8 Agent's Reimbursement and Indemnification. The Banks agree to reimburse
and indemnify the Agent  ratably in proportion to their  respective  Commitments
(or, if the Commitments have been terminated, in proportion to their Commitments
immediately prior to such termination) (i) for any amounts not reimbursed by the
Borrowers  for which the Agent is entitled  to  reimbursement  by the  Borrowers
under the Loan Documents,  (ii) for any other expenses  incurred by the Agent on
behalf of the Banks, in connection with the  preparation,  execution,  delivery,
administration  and  enforcement  of  the  Loan  Documents  and  (iii)  for  any
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs,  expenses or disbursements of any kind and nature whatsoever which may be
imposed on, incurred by or asserted  against the Agent in any way relating to or
arising out of the Loan Documents or any other document  delivered in connection
therewith or the transactions contemplated thereby, or the enforcement of any of
the terms thereof or of any such other documents, provided that no Bank shall be
liable  for any of the  foregoing  to the  extent  they  arise  from  the  gross
negligence or willful  misconduct  of the Agent.  The  obligations  of the Banks
under  this  Section  9.8 shall  survive  payment  of the Bank  Obligations  and
termination of this Agreement.

     9.9 Notice of Default.  The Agent shall not be deemed to have  knowledge or
notice of the occurrence of any Default or Event of Default hereunder unless the
Agent has received  written  notice from a Bank or a Borrower  referring to this
Agreement  describing  such  Default or Event of Default and  stating  that such
notice is a "notice of  default".  In the event that the Agent  receives  such a
notice, the Agent shall give prompt notice thereof to the Banks.

     9.10  Rights as a Bank.  In the event the Agent is a Bank,  the Agent shall
have the same rights and powers  hereunder  and under any other Loan Document as
any Bank and may exercise the same as though it were not the Agent, and the term
"Bank"  or  "Banks"  shall,  at any time when the  Agent is a Bank,  unless  the
context otherwise indicates,  include the Agent in its individual capacity.  The
Agent may accept deposits from, lend money to, and generally  engage in any kind
of trust, debt, equity or other  transaction,  in addition to those contemplated
by this Agreement or any other Loan Document,  with any Borrower or any of their
respective  Subsidiaries  in  which  any  Borrower  or  such  Subsidiary  is not
restricted  hereby  from  engaging  with any other  Person.  The  Agent,  in its
individual capacity, is not obligated to remain a Bank.

     9.11  Bank  Credit   Decision.   Each  Bank   acknowledges   that  it  has,
independently and without reliance upon the Agent or any other Bank and based on
the financial  statements prepared by the Borrowers and such other documents and
information  as it has  deemed  appropriate,  made its own credit  analysis  and
decision to enter into this  Agreement and the other Loan  Documents.  Each Bank
also  acknowledges  that it will,  independently  and without  reliance upon the



                                      E-94

<PAGE>


Agent or any other Bank and based on such documents and  information as it shall
deem  appropriate  at the time,  continue  to make its own credit  decisions  in
taking or not taking action under this Agreement and the other Loan Documents.

     9.12  Successor  Agent.  The Agent may resign at any time by giving written
notice thereof to the Banks and the Borrowers,  such resignation to be effective
upon the  appointment  of a successor  Agent or, if no successor  Agent has been
appointed,  forty-five  days  after  the  retiring  Agent  gives  notice  of its
intention to resign.  Upon any such  resignation,  the Required Banks shall have
the right to  appoint,  on behalf of the  Borrowers  and the Banks,  a successor
Agent.  If no successor Agent shall have been so appointed by the Required Banks
within thirty days after the resigning Agent's giving notice of its intention to
resign,  then the resigning Agent may appoint,  on behalf of the Borrowers,  and
the Banks, a successor  Agent.  If the Agent has resigned and no successor Agent
has been appointed,  the Banks may perform all the duties of the Agent hereunder
and the Borrowers shall make all payments in respect of the Bank  Obligations to
the  applicable  Bank and for all other  purposes  shall deal  directly with the
Banks. No successor  Agent shall be deemed to be appointed  hereunder until such
successor Agent has accepted the appointment.  Any such successor Agent shall be
a commercial bank having capital and retained earnings of at least  $50,000,000.
Upon the acceptance of any appointment as Agent hereunder by a successor  Agent,
such successor Agent shall  thereupon  succeed to and become vested with all the
rights,  powers,  privileges  and  duties  of  the  resigning  Agent.  Upon  the
effectiveness  of the  resignation  of the Agent,  the resigning  Agent shall be
discharged  from  its  duties  and  obligations  hereunder  and  under  the Loan
Documents.  After  the  effectiveness  of  the  resignation  of  an  Agent,  the
provisions  of this  Section 9 shall  continue in effect for the benefit of such
Agent in respect of any actions  taken or omitted to be taken by it while it was
acting as the Agent hereunder and under the other Loan Documents.

     9.13 Pro Rata  Sharing by Banks.  Each Bank  agrees  with every  other Bank
that,  in the event that it shall  receive  and retain any payment on account of
the  Borrower's  obligations  under this  Agreement,  the Notes or the  Security
Documents in a greater  proportion than that received by any other Bank, whether
such payment be voluntary, involuntary or by operation of law, by application of
set-off of any indebtedness or otherwise, then such Bank shall promptly purchase
a participation interest from the other Banks, without recourse, for cash and at
face value,  ratably in  accordance  with its Pro Rata Share,  in such an amount
that each Bank shall have  received  payment in respect of such  obligations  in
accordance with its Pro Rata Share; provided,  that if any such purchase be made
by any Bank and if any such excess payment  relating thereto or any part thereof
is thereafter  recovered from such Bank,  appropriate  adjustment in the related
purchase from the other Banks shall be made by rescission and restoration of the
purchase  price as to the portion of such  excess  payment so  recovered.  It is
further  agreed that,  to the extent there is then owing by the Borrowers to any
Bank indebtedness other than that evidenced by this Agreement, the Notes and the
Security  Documents  to which such Bank may apply any  involuntary  payments  of
indebtedness by the Borrowers, including those resulting from exercise of rights
of  set-off  or  similar  rights,  such Bank  shall  apply all such  involuntary
payments first to obligations of the Borrowers to the Banks  hereunder and under
the Notes and the Security Documents and then to such other indebtedness owed to
it by the Borrowers. In addition, it is further agreed that any and all proceeds
resulting  from a sale or  other  disposition  of any  collateral  which  may be
hereafter  granted for the benefit of the Banks to secure the obligations of the
Borrowers  hereunder,  shall be applied first to obligations of the Borrowers to
the Banks  hereunder  and under the Notes and the Security  Documents,  and then
ratably to any other  indebtedness  owed by the  Borrowers to the Banks which is
secured by such collateral.

     9.14  Determination  of Borrowing  Base, Etc. (a) As of the Effective Date,
the  Borrowing  Base  shall be  equal  to  $162,500,000  and  scheduled  monthly
reductions  to the  Borrowing  Base shall be $0 (any monthly  reductions  in the
Borrowing Base  redetermined  at any time under this Section 9.14 are defined as
the "Monthly Borrowing Base Reductions").




                                      E-95

<PAGE>



          (b)  Any  redetermination  of  the  Borrowing  Base  and  the  Monthly
Borrowing Base Reductions shall be made by the Agent and submitted to the Banks.
Such  redetermined  Borrowing Base and Monthly  Borrowing Base Reductions  shall
then be  effective  when  approved  by Banks  holding  not less  than 75% of the
aggregate  principal  amount of the  Advances  then  outstanding  (or 75% of the
Commitments if no Advances are then  outstanding).  If any of such  redetermined
Borrowing Base and Monthly  Borrowing Base  Reductions are not approved by Banks
holding not less than 75% of the aggregate principal amount of the Advances then
outstanding  (or 75% of the  Commitments  if no Advances  are then  outstanding)
within  ten (10) days  after they are  submitted  to the Banks,  each Bank shall
submit to the Agent,  on or within ten (10) days  after the Agent  notifies  the
Banks that such Banks have not approved any such redetermined  Borrowing Base or
Monthly  Borrowing Base Reductions,  its  determination of each of the foregoing
which was not so approved,  and the redetermined amount of each of the foregoing
which  was  not so  approved  will  be  based  on the  weighted  average  of the
redetermined   amount  thereof  of  each  Bank  which   properly   submits  such
redetermination to the Agent, weighted according to each Bank's Commitment.

NOTWITHSTANDING  ANYTHING  HEREIN TO THE  CONTRARY,  WITHOUT  THE PRIOR  WRITTEN
APPROVAL OF ALL THE BANKS,  SUCH APPROVAL TO BE IN EACH BANK'S SOLE  DISCRETION,
(1) THE BORROWING BASE MAY NOT BE GREATER THAN $162,500,000 AT ANY TIME, (2) THE
REDETERMINATION  OF THE BORROWING BASE AND THE MONTHLY BORROWING BASE REDUCTIONS
SCHEDULED TO OCCUR ON OR ABOUT OCTOBER, 1999 SHALL BE EFFECTIVE WHEN APPROVED BY
ALL OF THE BANKS AND (3) THE MONTHLY BORROWING BASE REDUCTIONS DETERMINED AT ANY
TIME AND IN ACCORDANCE WITH THE ABOVE PROCEDURE MAY NOT BE MODIFIED.

          (c) The Borrowing Base and the Monthly  Borrowing Base  Reductions may
be  redetermined  from time to time as requested by the Required Banks (provided
that the Required Banks may not request any such optional  redetermination until
after the mandatory redetermination scheduled to occur on or about October, 1999
unless any representation or warranty contained in Section 6 hereof shall not be
true and  correct in all  material  respects  at any time as if made at any such
time), and will be redetermined upon the request of the Borrowers (provided that
the Borrowers  cannot request a  redetermination  of the Borrowing  Base, or the
Monthly   Borrowing  Base  Reductions  more  than  once  between  the  mandatory
redeterminations  hereinafter  provided for),  and, in addition,  at least twice
each year (provided that the first such redetermination  shall not be made until
October,  1999) as follows:  upon receipt of the reserve reports  referred to in
Section  7.1(d)(vii)  hereof  (and  in  connection  with  such  twice  per  year
redeterminations of the Borrowing Base and the Monthly Borrowing Base Reductions
the Agent shall submit the redetermined Borrowing Base and the Monthly Borrowing
Base Reductions as required under this Section 9.14 on or prior to 30 days after
the receipt of each (i) reserve report  referred to in Section  7.1(d)(vii)  (A)
hereof and (ii)  reserve  report  referred to in Section  7.1(d)(vii)(B)).  Each
redetermination  of the Monthly  Borrowing Base Reductions  shall determine such
reductions for each of the six months following such  determination.  Except for
the scheduled  redeterminations  of the Borrowing Base and the Monthly Borrowing
Base Reductions,  each Bank requesting a  redetermination  of the Borrowing Base
and the Monthly Borrowing Base Reductions agrees to give notice to the Agent and
the Borrowers of such request.

          (d) Within  five days after  notification  to  Borrower of a Borrowing
Base  redetermination  pursuant to the  provisions  of this  Section  9.14,  the
Borrowers may notify Agent as to what portion of the Borrowing  Base they desire
access (the "Elected  Borrowing  Limit").  Thereafter,  the Borrowers may obtain
Advances which do not exceed in the aggregate the lesser of (i) the  Commitments
or  (ii)  the   Elected   Borrowing   Limit  until  the  next   Borrowing   Base
redetermination,  subject to the provisions of Section 9.14(b) and (c) above. If
no such  notification is received by the Agent the Elected Borrowing Limit shall
be the Borrowing Base as so determined.  Notwithstanding  anything herein to the
contrary,  the  Elected  Borrowing  Limit may not  exceed  the lesser of (A) the



                                      E-96

Borrowing Base or (B) the aggregate stated Commitment  amounts for the Banks set
forth  next  to the  names  of  the  Banks  on the  signature  pages  hereof  or
established  pursuant to Section 10.6, as the case may be, as such amount may be
reduced from time to time. As of the Effective Date, the Elected Borrowing Limit
shall be equal to $162,500,000.

     9.15 Syndication and Documentation Agent.  Toronto Dominion (Texas),  Inc.,
as Syndication Agent hereunder,  and Paribas,  as Documentation Agent hereunder,
shall have no duties or liabilities hereunder in such capacities.

     SECTION 10. Miscellaneous.

     10.1  Amendments;  Etc. (a) This Agreement and any term or provision hereof
may be amended, waived or terminated by an instrument in writing executed by the
Borrowers and the Required Banks,  and to the extent any rights or duties of the
Agent may be  affected  thereby,  the  Agent,  provided,  that,  notwithstanding
anything in this  Agreement to the contrary,  except by an instrument in writing
executed by the Borrowers  and all of the Banks,  no such  amendment,  waiver or
termination  shall  authorize  or permit the  extension  of the time or times of
payment of the  principal  of, or  interest  on, the Notes or the  reduction  in
principal  amount thereof or the rate of interest  thereon,  or any fees payable
hereunder,  or increase or extend the aggregate  Commitments  or the  respective
Commitments  of any  Bank,  or  change  the  percentage  of Banks  required  for
approvals of the  Borrowing  Base as specified in Section  9.14,  or release any
Borrower from any of its obligations hereunder or under any other Loan Document,
or release any material amount of the Collateral from the Liens granted pursuant
hereto or the Security Documents, or amend this Section 10.1.

          (b) Any such amendment,  waiver or termination shall be effective only
in the specific instance and for the specific purpose for which given.

          (c) Notwithstanding anything herein to the contrary, any Bank that has
failed to fund any  Advance or other  amount  required to be funded by such Bank
hereunder  shall not be entitled to vote  (whether to consent or to withhold its
consent) with respect to any amendment,  modification,  termination or waiver of
any  provision of any Loan  Document or a departure  therefrom or any  direction
from the Banks to the Agent and, for purposes of determining the Required Banks,
the Commitments and Advances of such Bank shall be disregarded.

     10.2 Notices.  (a) Except as otherwise  provided in Section 10.2(c) hereof,
all notices,  requests,  consents and other communications hereunder shall be in
writing and shall be delivered or sent to the Borrowers, the Banks and the Agent
at the respective addresses for notices set forth on the signature pages hereof,
or to such other address as may be designated by the Borrowers, the Agent or any
Bank by notice to the other parties hereto.  All notices shall be deemed to have
been given at the time of actual delivery thereof to such address, or if sent by
the Agent or any Bank to the Borrowers by certified or registered mail,  postage
prepaid, to such address, on the fifth day after the date of mailing.

          (b) Notices by the Borrowers to the Agent with respect to requests for
Advances  pursuant to Section 3.1 and notices of prepayment  pursuant to Section
4.1(c) shall be irrevocable and binding on the Borrowers.

          (c) Any notice to be given by the  Borrowers to the Agent  pursuant to
Section  4.1(c) or  Section  3.1 and any  notice to be given by the Agent or any
Bank hereunder, may be given by telephone, by telex or by facsimile transmission



                                      E-97

<PAGE>


and must be immediately  confirmed in writing in the manner  provided in Section
10.2(a).  Any such notice given by  telephone,  telex or facsimile  transmission
shall be deemed  effective upon receipt thereof by the party to whom such notice
is given.

     10.3 Conduct No Waiver;  Remedies  Cumulative.  No course of dealing on the
part of the  Agent or the  Banks,  nor any delay or  failure  on the part of the
Agent or any Bank in exercising any right,  power or privilege  hereunder  shall
operate as a waiver of such right, power or privilege or otherwise prejudice the
Agent's or the Banks'  rights and  remedies  hereunder;  nor shall any single or
partial  exercise  thereof preclude any further exercise thereof or the exercise
of any other right,  power or privilege.  No right or remedy  conferred  upon or
reserved  to the Agent or the Banks  under  this  Agreement  is  intended  to be
exclusive  of any other  right or remedy,  and every  right and remedy  shall be
cumulative and in addition to every other right or remedy given hereunder or now
or hereafter  existing under any applicable law. Every right and remedy given by
this  Agreement or by applicable  law to the Agent or the Banks may be exercised
from time to time and as often as may be deemed expedient by them.

     10.4 Reliance on and Survival of Various Provisions.  All terms, covenants,
agreements,  representations  and  warranties of the Borrowers made herein or in
any certificate or other document  delivered  pursuant hereto shall be deemed to
be  material  and to have been  relied  upon by the Banks,  notwithstanding  any
investigation  heretofore or hereafter made by any Bank or on any Bank's behalf,
and those  covenants  and  agreements of the Borrowers set forth in Section 10.5
hereof shall survive the repayment in full of the Advances and other obligations
of the Borrowers  hereunder and under Security  Documents and the termination of
the Commitments.

     10.5 Expenses; Indemnification. (a) The Borrowers agree to pay and save the
Agent  harmless  from  liability  for the  payment  of the  reasonable  fees and
expenses  of any  counsel  the  Agent  shall  employ,  in  connection  with  the
preparation,  execution  and  delivery  of this  Agreement,  the  Notes  and the
Security Documents and the consummation of the transactions  contemplated hereby
and in connection with any amendments,  waivers or consents and other matters in
connection therewith, and all reasonable costs and expenses of the Agent and the
Banks (including reasonable fees and expenses of counsel) in connection with any
enforcement of this Agreement, the Notes or the Security Documents.

                  (b) Each of the  Borrowers  hereby  indemnifies  and agrees to
hold harmless the Banks and the Agent, and their respective officers, directors,
employees  and agents,  from and against  any and all claims,  damages,  losses,
liabilities,  costs or expenses of any kind or nature whatsoever which the Banks
or the Agent or any such Person may incur or which may be claimed against any of
them by reason of or in  connection  with any Letter of Credit,  and neither any
Bank nor the Agent or any of their respective officers, directors,  employees or
agents shall be liable or responsible  for: (i) the use which may be made of any
Letter of Credit or for any acts or omissions of any  beneficiary  in connection
therewith; (ii) the validity,  sufficiency or genuineness of documents or of any
endorsement thereon, even if such documents should in fact prove to be in any or
all respects invalid,  insufficient,  fraudulent or forged; (iii) payment by the
Agent to the  beneficiary  under any Letter of Credit  against  presentation  of
documents which do not comply with the terms of any Letter of Credit,  including
failure of any  documents to bear any  reference  or adequate  reference to such
Letter  of  Credit;  (iv)  any  error,   omission,   interruption  or  delay  in
transmission,   dispatch  or   delivery  of  any  message  or  advice,   however
transmitted,  in connection with any Letter of Credit; or (v) any other event or
circumstance  whatsoever  arising  in  connection  with any  Letter  of  Credit;
provided,  however,  that the  Borrowers  shall not be required to indemnify the
Agent and such other Persons,  and the Agent shall be liable to the Borrowers to
the extent,  but only to the extent,  of any direct, as opposed to consequential
or  incidental,  damages  suffered by any Borrower  which were caused by (A) the
Agent's  wrongful  dishonor of any Letter of Credit after the presentation to it
by the  beneficiary  thereunder of a draft or other demand for payment and other
documentation strictly complying with the terms and conditions of such Letter of
Credit,  or (B) the payment by the Agent to the beneficiary  under any Letter of



                                      E-98

<PAGE>


Credit against  presentation  of documents which do not comply with the terms of
the Letter of Credit to the extent,  but only to the extent,  that such  payment
constitutes gross negligence or wilful misconduct of the Agent. It is understood
that in making  any  payment  under a Letter of  Credit  the Agent  will rely on
documents  presented to it under such Letter of Credit as to any and all matters
set forth therein without further  investigation and regardless of any notice or
information  to the contrary,  and such reliance and payment  against  documents
presented  under a Letter  of  Credit  substantially  complying  with the  terms
thereof shall not be deemed gross  negligence or wilful  misconduct of the Agent
in connection with such payment.  It is further  acknowledged  and agreed that a
Borrower may have rights against the  beneficiary  or others in connection  with
any Letter of Credit with respect to which the Agent is alleged to be liable and
it shall be a precondition  of the assertion of any liability of the Agent under
this  Section  that such  Borrower  shall first have taken  reasonable  steps to
enforce remedies in respect of the alleged loss against such beneficiary and any
other parties  obligated or liable in connection  with such Letter of Credit and
any related transactions.

          (c) In  consideration  of the execution and delivery of this Agreement
by  each  Bank  and the  extension  of the  Commitments,  the  Borrowers  hereby
indemnify,  exonerate and hold the Agent, each Bank and each of their respective
officers,  directors,  employees  and  agents  (collectively,  the  "Indemnified
Parties")  free and  harmless  from and against any and all  actions,  causes of
action, suits, losses, costs,  liabilities and damages, and expenses incurred in
connection  therewith  (irrespective of whether any such Indemnified  Party is a
party to the action for which  indemnification  hereunder is sought),  including
reasonable  attorneys' fees and  disbursements  (collectively,  the "Indemnified
Liabilities"),  incurred by the  Indemnified  Parties or any of them as a result
of, or arising out of, or relating to:

               (i) any  transaction  financed  or to be  financed in whole or in
part, directly or indirectly, with the proceeds of any Advance;

               (ii) the entering into and  performance of this Agreement and any
other  agreement or  instrument  executed in  connection  herewith by any of the
Indemnified  Parties  (including  any  action  brought  by or on  behalf  of the
Borrowers as the result of any  determination  by the Required Banks not to fund
any Advance in compliance with this Agreement);

               (iii) any investigation,  litigation or proceeding related to any
acquisition   or  proposed   acquisition  by  the  Borrowers  or  any  of  their
Subsidiaries of any portion of the stock or assets of any Person, whether or not
the Agent or such Bank is party thereto;

               (iv) any  investigation,  litigation or proceeding related to any
environmental cleanup, audit, compliance or other matter relating to any release
by the Borrowers or any of their  Subsidiaries of any hazardous  material or any
violations of Environmental Laws; or

               (v) the presence on or under,  or the escape,  seepage,  leakage,
spillage, discharge,  emission,  discharging or releases from, any real property
owned or operated by the  Borrowers or any  Subsidiary  thereof of any Hazardous
Material (including any losses, liabilities,  damages, injuries, costs, expenses
or claims  asserted  or arising  under any  Environmental  Law),  regardless  of
whether  caused by, or within the control of, the Borrowers or such  Subsidiary,
except  for any  such  Indemnified  Liabilities  arising  for the  account  of a
particular  Indemnified  Party by reason of the  activities  of the  Indemnified
Party on the property of the Borrowers conducted  subsequent to a foreclosure on
such  property  by the Banks or by reason of the  relevant  Indemnified  Party's
gross negligence or wilful misconduct or breach of this Agreement, and if and to
the extent that the foregoing  undertaking may be unenforceable  for any reason,
the Borrowers  hereby agree to make the maximum  contribution to the payment and
satisfaction of each of the Indemnified  Liabilities  which is permissible under



                                      E-99

<PAGE>


applicable  law. The Borrowers  shall be obligated to indemnify the  Indemnified
Parties for all Indemnified Liabilities subject to and pursuant to the foregoing
provisions, regardless of whether the Borrowers or any of their Subsidiaries had
knowledge  of the  facts  and  circumstances  giving  rise to  such  Indemnified
Liability.

         10.6  Successors and Assigns.  (a) This Agreement shall be binding upon
and inure to the benefit of the parties hereto and their  respective  successors
and assigns,  provided that the Borrowers may not,  without the prior consent of
the Banks,  assign their rights or obligations  hereunder or under the Notes and
the Banks shall not be  obligated  to make any Advance  hereunder  to any entity
other than the Borrowers.

          (b) Any  Bank  may  sell a  participation  interest  to any  financial
institution or institutions,  and such financial institution or institutions may
further sell, a participation  interest  (undivided or divided) in, the Advances
and such Bank's  rights and  benefits  under this  Agreement,  the Notes and the
Security Documents and to the extent of that participation,  such participant or
participants shall have the same rights and benefits against the Borrowers under
Section 6.2(c) as it or they would have had if participation of such participant
or  participants  were the Bank making the Advances to the Borrowers  hereunder,
provided,  however,  that (i) such Bank's obligations under this Agreement shall
remain  unmodified and fully effective and  enforceable  against such Bank, (ii)
such Bank shall remain solely  responsible  to the other parties  hereto for the
performance of such obligations,  (iii) such Bank shall remain the holder of its
Note for all purposes of this Agreement,  (iv) the Borrowers,  the Agent and the
other  Banks  shall  continue  to deal  solely  and  directly  with such Bank in
connection with such Bank's rights and obligations under this Agreement, and (v)
such Bank shall not grant to its  participant  any rights to consent or withhold
consent to any action taken by such Bank or the Agent under this Agreement other
than action requiring the consent of all of the Banks hereunder.  The Agent from
time to time in its sole  discretion  may  appoint  agents  for the  purpose  of
servicing and  administering  this Agreement and the  transactions  contemplated
hereby and enforcing or exercising  any rights or remedies of the Agent provided
under this Agreement,  the Notes,  or otherwise.  In furtherance of such agency,
the Agent may from  time to time  direct  that the  Borrowers  provide  notices,
reports  and other  documents  contemplated  by this  Agreement  (or  duplicates
thereof) to such agent.  The Borrowers hereby consent to the appointment of such
agent and agree to provide all such notices,  reports and other documents and to
otherwise  deal with such agent acting on behalf of the Agent in the same manner
as would be required if dealing with the Agent itself.

          (c) Each Bank may,  with the prior  consent  of the  Borrowers  (which
consent  shall not be  unreasonably  withheld and shall not be required upon the
occurrence and during the continuance of any Event of Default which is not cured
or  waived  within 30 days (or 0 days in the case of an Event of  Default  under
Section  8.1(g))  after  the  occurrence  of such  Event of  Default  or if such
assignment  by such Bank is to an Affiliate of such Bank or to another Bank) and
the Agent, assign to one or more banks or other entities all or a portion of its
rights and obligations under this Agreement (including,  without limitation, all
or a portion of its  Commitment,  the Advances owing to it and the Note or Notes
and the Security  Documents held by it); provided,  however,  that (i) each such
assignment  shall be of a uniform,  and not a varying,  percentage of all rights
and  obligations,  (ii) except in the case of an  assignment  of all of a Bank's
rights and obligations under this Agreement, (A) the amount of the Commitment of
the assigning Bank being assigned  pursuant to each such assignment  (determined
as of the date of the Assignment and Acceptance with respect to such assignment)
shall  in no  event  be less  than  $5,000,000,  and in  integral  multiples  of
$1,000,000 thereafter,  or such lesser amount as the Borrowers and the Agent may
consent to and (B) after giving  effect to each such  assignment,  the amount of
the Commitment of the assigning Bank shall in no event be less than  $5,000,000,
and (iii) the parties to each such  assignment  shall execute and deliver to the
Agent,  for its  acceptance  and  recording in the Register,  an Assignment  and
Acceptance  in the form of Exhibit D hereto (an  "Assignment  and  Acceptance"),
together with any Note or Notes subject to such  assignment and a processing and
recordation  fee of  $3,500.  Upon  such  execution,  delivery,  acceptance  and
recording,  from and after the effective date  specified in such  Assignment and
Acceptance,  (x) the  assignee  thereunder  shall be a party  hereto and, to the
extent that rights and  obligations  hereunder have been assigned to it pursuant



                                      E-100

<PAGE>


to such  Assignment and  Acceptance,  have the rights and  obligations of a Bank
hereunder and (y) the Bank assignor  thereunder shall, to the extent that rights
and  obligations  hereunder have been assigned by it pursuant to such Assignment
and Acceptance, relinquish its rights and be released from its obligations under
this Agreement (and, in the case of an Assignment and Acceptance covering all of
the remaining  portion of an assigning Bank's rights and obligations  under this
Agreement, such Bank shall cease to be a party hereto).

          (d) By executing and delivering an Assignment and Acceptance, the Bank
assignor  thereunder and the assignee  thereunder confirm to and agree with each
other and the other  parties  hereto as  follows:  (i) other than as provided in
such Assignment and Acceptance,  such assigning Bank makes no  representation or
warranty  and  assumes  no  responsibility   with  respect  to  any  statements,
warranties or  representations  made in or in connection  with this Agreement or
the execution, legality, validity, enforceability,  genuineness,  sufficiency or
value of this Agreement or any other instrument or document  furnished  pursuant
hereto; (ii) such assigning Bank makes no representation or warranty and assumes
no  responsibility  with respect to the financial  condition of the Borrowers or
the performance or observance by the Borrowers of any of their obligations under
this Agreement or any other  instrument or document  furnished  pursuant hereto;
(iii) such  assignee  confirms  that it has  received a copy of this  Agreement,
together with copies of the financial  statements referred to in Section 6.7 and
such other  documents and  information as it has deemed  appropriate to make its
own credit  analysis and decision to enter into such  Assignment and Acceptance;
(iv) such assignee will,  independently  and without reliance on the Agent, such
assigning Bank or any other Bank and based on such documents and  information as
it shall deem appropriate at the time, continue to make its own credit decisions
in taking or not taking action under this Agreement;  (v) such assignee appoints
and  authorizes  the Agent to take such  action  as agent on its  behalf  and to
exercise such powers and discretion under this Agreement as are delegated to the
Agent by the terms  hereof,  together  with such  powers and  discretion  as are
reasonably  incidental  thereto;  and (vi)  such  assignee  agrees  that it will
perform in accordance with their terms all of the obligations  that by the terms
of this Agreement are required to be performed by it as a Bank.

          (e)  The  Agent  shall  maintain  at  its  address  designated  on the
signature pages hereof a copy of each Assignment and Acceptance delivered to and
accepted by it and a register for the  recordation of the names and addresses of
the Banks and the Commitment of, and principal  amount of the Advances owing to,
each Bank from time to time (the "Register").  The entries in the Register shall
be  conclusive  and binding for all purposes,  absent  manifest  error,  and the
Borrowers,  the Agent and the Banks may treat each Person whose name is recorded
in the  Register as a Bank  hereunder  for all purposes of this  Agreement.  The
Register  shall be available for  inspection by the Borrowers or any Bank at any
reasonable time and from time to time upon reasonable prior notice.

          (f) Upon its receipt of an Assignment  and  Acceptance  executed by an
assigning Bank and an assignee,  together with any Note or Notes subject to such
assignment,  the  Agent  shall,  if such  Assignment  and  Acceptance  has  been
completed,   (i)  accept  such  Assignment  and  Acceptance,   (ii)  record  the
information  contained  therein in the  Register  and (iii) give  prompt  notice
thereof to the  Borrowers.  Within five  Business Days after its receipt of such
notice,  the Borrowers,  at their own expense,  shall execute and deliver to the
Agent in exchange for the  surrendered  Note or Notes a new Note to the order of
such  assignee in an amount  equal to the  Commitment  assumed by it pursuant to
such  Assignment  and  Acceptance  and,  if the  assigning  Bank has  retained a
Commitment hereunder, a new Note to the order of the assigning Bank in an amount
equal to the Commitment  retained by it hereunder.  Such new Note or Notes shall
be in an aggregate  principal amount equal to the aggregate  principal amount of
such  surrendered  Note or  Notes,  shall be dated  the  effective  date of such
Assignment and Acceptance and shall  otherwise be in  substantially  the form of
Exhibit B hereto.



                                      E-101

          (g) The Banks may, in connection with any assignment or  participation
or proposed assignment or participation  pursuant to this Section 10.6, disclose
to the  assignee  or  participant  or  proposed  assignee  or  participant,  any
information  relating to the Borrowers,  provided that such proposed assignee or
participant  has agreed to hold such  information  confidential  under the terms
described in Section 10.20.

          (h)  Notwithstanding any other provisions set forth in this Agreement,
any Bank may at any time create a security  interest  in, or assign,  all or any
portion of its rights under this Agreement (including,  without limitation,  the
Advances  owing to it and the Note or Notes held by it) in favor of any  Federal
Reserve Bank in  accordance  with  Regulation A of the Board of Governors of the
Federal  Reserve System;  provided that such creation of a security  interest or
assignment  shall  not  release  such  Bank  from  its  obligations  under  this
Agreement.

     10.7  Subsidiaries  as  Borrowers.  In the  event  that CRI,  COG,  COGL or
Offshore shall create or acquire a Subsidiary,  such Subsidiary  shall execute a
joinder agreement in form and substance satisfactory to the Agent, together with
such  Security  Documents,  other  documents  and  opinions  as  the  Agent  may
reasonably require, and shall become a Borrower hereunder.

     10.8  CHOICE OF LAW.  THE LOAN  DOCUMENTS  (OTHER THAN THOSE  CONTAINING  A
CONTRARY  EXPRESS CHOICE OF LAW PROVISION) SHALL BE CONSTRUED IN ACCORDANCE WITH
THE INTERNAL LAWS (AND NOT THE LAW OF  CONFLICTS) OF THE STATE OF ILLINOIS,  BUT
GIVING EFFECT TO FEDERAL LAWS APPLICABLE TO NATIONAL BANKS.

     10.9 Table of Contents and Headings. The table of contents and the headings
of the various subdivisions hereof are for the convenience of reference only and
shall in no way modify any of the terms or provisions hereof.

     10.10  Construction  of  Certain  Provisions.   All  computations  required
hereunder  and all  financial  terms used herein  shall be made or  construed in
accordance  with GAAP unless such principles are  inconsistent  with the express
requirements of this Agreement. If any provision of this Agreement refers to any
action  to be taken by any  Person,  or which  such  Person is  prohibited  from
taking, such provision shall be applicable whether such action is taken directly
or  indirectly  by such  Person,  whether  or not  expressly  specified  in such
provision.

     10.11  Integration  and  Severability.  This Agreement  embodies the entire
agreement and understanding  between the Borrowers and the Banks, and supersedes
all prior agreements and understandings,  relating to the subject matter hereof.
In  case  any  one or  more  of the  obligations  of the  Borrowers  under  this
Agreement,  the Notes or any  Security  Documents  shall be invalid,  illegal or
unenforceable in any jurisdiction,  the validity, legality and enforceability of
the remaining  obligations of the Borrowers  shall not in any way be affected or
impaired thereby,  and such invalidity,  illegality or  unenforceability  in one
jurisdiction  shall not affect the validity,  legality or  enforceability of the
obligations  of the Borrowers  under this  Agreement,  the Notes or any Security
Documents in any other jurisdiction.

     10.12  Interest Rate  Limitation.  Notwithstanding  any  provisions of this
Agreement,  the Notes or any Security Documents, in no event shall the amount of
interest paid or agreed to be paid by the Borrowers exceed an amount computed at
the highest  rate of interest  permissible  under  applicable  law. If, from any
circumstances  whatsoever,  fulfillment of any provision of this Agreement,  the
Notes or any Security  Documents at the time performance of such provision shall
be due, shall involve exceeding the interest rate limitation  validly prescribed



                                      E-102

by law which a court of competent jurisdiction may deem applicable hereto, then,
ipso  facto,  the  obligations  to be  fulfilled  shall be  reduced to an amount
computed at the highest rate of interest  permissible  under applicable law, and
if for any reason  whatsoever the Banks shall ever receive as interest an amount
which would be deemed  unlawful under such applicable law such interest shall be
automatically  applied to the payment of principal  of the Advances  outstanding
and other  obligations of the Borrowers  hereunder  (whether or not then due and
payable)  and not to the  payment  of  interest,  or  shall be  refunded  to the
Borrowers  if such  principal  has been  paid in full.  Anything  herein  to the
contrary notwithstanding,  the obligations of the Borrowers under this Agreement
shall be  subject to the  limitation  that  payments  of  interest  shall not be
required  to the extent that  receipt of any such  payment by the Banks would be
contrary to provisions  of law  applicable to the Banks which limits the maximum
rate of interest which may be charged or collected by the Banks.

     10.13  Counterparts.  This  Agreement  may be  executed  in any  number  of
counterparts,  all of which taken  together  shall  constitute  one and the same
instrument  and any of the parties  hereto may execute this Agreement by signing
any such counterpart.

     10.14  Independence  of Covenants.  All covenants  hereunder shall be given
independent  effect so that if a particular action or condition is not permitted
by any such covenant, the fact that it would be permitted by an exception to, or
would be otherwise  within the limitations of, another  covenant shall not avoid
the  occurrence  of an Event of  Default  or any event or  condition  which with
notice or lapse of time, or both,  could become such an Event of Default if such
action is taken or such condition exists.

     10.15  Consent  to  Jurisdiction.   Notwithstanding  the  place  where  any
liability  originates  or  arises,  or is to be  repaid,  any  suit,  action  or
proceeding arising out of or relating to this Agreement, any Security Documents,
or the Notes may be  instituted  in any court of competent  jurisdiction  in the
State of Illinois,  each Borrower hereby  irrevocably waives any objection which
it may have or  hereafter  has to the  laying  of such  venue of any such  suit,
action or proceeding and any claim that any such suit,  action or proceeding has
been brought in an  inconvenient  forum,  and each Borrower  hereby  irrevocably
submits  its Person and  property to the  jurisdiction  of any such court in any
such suit, action or proceedings. Nothing in this Section 10.15 shall affect the
right of the Bank to bring  proceedings  against the  Borrowers  or any of their
property in the courts of any other court of competent jurisdiction.

     10.16 JURY TRIAL  WAIVER.  THE AGENT,  THE BANKS AND EACH  BORROWER,  AFTER
CONSULTING OR HAVING HAD THE  OPPORTUNITY  TO CONSULT WITH  COUNSEL,  KNOWINGLY,
VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHT ANY OF THEM MAY HAVE TO A TRIAL BY
JURY IN ANY LITIGATION  BASED UPON OR ARISING OUT OF THIS AGREEMENT,  THE NOTES,
THE SECURITY  DOCUMENTS,  OR ANY RELATED  INSTRUMENT  OR AGREEMENT OR ANY OF THE
TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT, THE NOTES OR THE SECURITY DOCUMENTS
OR ANY COURSE OF  CONDUCT,  DEALING,  STATEMENTS  (WHETHER  ORAL OR  WRITTEN) OR
ACTIONS OF ANY OF THEM. NEITHER THE AGENT, THE BANKS NOR ANY BORROWER SHALL SEEK
TO CONSOLIDATE,  BY  COUNTERCLAIM OR OTHERWISE,  ANY SUCH ACTION IN WHICH A JURY
TRIAL HAS BEEN WAIVED WITH ANY OTHER  ACTION IN WHICH A JURY TRIAL  CANNOT BE OR
HAS NOT BEEN WAIVED.  THESE PROVISIONS SHALL NOT BE DEEMED TO HAVE BEEN MODIFIED
IN ANY  RESPECT  OR  RELINQUISHED  BY  EITHER  THE  AGENT  AND THE  BANKS OR THE
BORROWERS EXCEPT BY A WRITTEN INSTRUMENT EXECUTED BY ALL OF THEM.

     10.17 Joint and Several Obligations;  Contribution Rights;  Savings Clause.
(a) Notwithstanding  anything to the contrary set forth herein or in any Note or
in any other Loan Document, the obligations of the Borrowers hereunder and under
the Notes and the other Loan Documents are joint and several.



                                      E-103

          (b)  If  any  Borrower   makes  a  payment  in  respect  of  the  Bank
Obligations,  it shall have the rights of  contribution  set forth below against
the other Borrowers; provided that such Borrower shall not exercise its right of
contribution until all the Bank Obligations shall have been finally paid in full
in cash. If any Borrower makes a payment in respect of the Bank Obligations that
is smaller in proportion to its Payment Share (as hereinafter defined) than such
payments  made by the other  Borrowers are in proportion to the amounts of their
respective  Payment  Shares,  the Borrower making such  proportionately  smaller
payment  shall,  when  permitted  by the  preceding  sentence,  pay to the other
Borrowers an amount such that the net  payments  made by the Borrower in respect
of the  Bank  Obligations  shall  be  shared  among  the  Borrowers  pro rata in
proportion to their  respective  Payment  Shares.  If any Borrower  receives any
payment that is greater in proportion  to the amount of its Payment  Shares than
the payments received by the other Borrowers are in proportion to the amounts of
their respective  Payment Shares,  the Borrower  receiving such  proportionately
greater payment shall, when permitted by the second preceding  sentence,  pay to
the other  Borrowers an amount such that the payments  received by the Borrowers
shall be shared among the Borrowers  pro rata in proportion to their  respective
Payment  Shares.  Notwithstanding  anything to the  contrary  contained  in this
paragraph or in this Agreement,  no liability or obligation of any Borrower that
shall  accrue  pursuant to this  paragraph  shall be paid nor shall it be deemed
owed  pursuant  to this  paragraph  until all of the Bank  Obligations  shall be
finally paid in full in cash.

     For purposes hereof,  the "Payment Share" of each Borrower shall be the sum
of (a) the aggregate proceeds of the Bank Obligations  received by such Borrower
plus (b) the product of (i) the aggregate Bank  Obligations  remaining unpaid on
the date such Bank Obligations become due and payable in full, whether by stated
maturity,  acceleration,  or otherwise (the "Determination Date") reduced by the
amount of such Bank Obligations  attributed to all or such Borrowers pursuant to
clause  (a)  above,  times  (ii) a  fraction,  the  numerator  of  which is such
Borrower's net worth on the effective  date of this Agreement  (determined as of
the end of the immediately  preceding fiscal reporting period of such Borrower),
and the denominator of which is the aggregate net worth of all Borrowers on such
effective date.

          (c) It is the  intent of each  Borrower,  the Agent and the Banks that
each Borrower's maximum Bank Obligations shall be in, but not in excess of:

               (i) in a case or proceeding commenced by or against such Borrower
under the  Bankruptcy  Code on or within  one year from the date on which any of
the Bank  Obligations are incurred,  the maximum amount that would not otherwise
cause the Bank  Obligations  (or any other  obligations  of such Borrower to the
Agent and the Banks) to be avoidable  or  unenforceable  against  such  Borrower
under  (A)  Section  548 of the  Bankruptcy  Code  or (B) any  state  fraudulent
transfer  or  fraudulent  conveyance  act or  statute  applied  in such  case or
proceeding by virtue of Section 544 of the Bankruptcy Code; or

               (ii)  in a  case  or  proceeding  commenced  by or  against  such
Borrower under the Bankruptcy Code subsequent to one year from the date on which
any of the Bank  Obligations  are  incurred,  the maximum  amount that would not
otherwise cause the Bank Obligations (or any other  obligations of such Borrower
to the Agent and the  Banks)  to be  avoidable  or  unenforceable  against  such
Borrower  under any state  fraudulent  transfer or fraudulent  conveyance act or
statute  applied in any such case or  proceeding by virtue of Section 544 of the
Bankruptcy Code; or

               (iii)  in a case  or  proceeding  commenced  by or  against  such
Borrower under any law,  statute or regulation  other than the  Bankruptcy  Code
(including,   without   limitation,   any  other   bankruptcy,   reorganization,
arrangement,  moratorium,  readjustment  of debt,  dissolution,  liquidation  or
similar debtor relief laws),  the maximum amount that would not otherwise  cause
the Bank Obligations (or any other obligations of such Borrower to the Agent and



                                      E-104

<PAGE>


the Banks) to be avoidable or  unenforceable  against such  Borrower  under such
law, statute or regulation including,  without limitation,  any state fraudulent
transfer or  fraudulent  conveyance  act or statute  applied in any such case or
proceeding.

          (d) The Borrowers  acknowledge and agree that they have requested that
the Banks make credit available to the Borrowers with each Borrower expecting to
derive  benefit,  directly  and  indirectly,  from the Advances and other credit
extended by the Banks to the Borrowers.

     10.18  Consents to Renewals,  Modifications  and Other  Actions and Events.
This  Agreement  and all of the  obligations  of the Borrowers  hereunder  shall
remain in full force and  effect  without  regard to and shall not be  released,
affected or impaired by: (a) any amendment,  assignment,  transfer, modification
of or addition or supplement to the Bank Obligations,  this Agreement,  any Note
or any other Loan Document; (b) any extension,  indulgence, increase in the Bank
Obligations  or other action or inaction in respect of any of the Loan Documents
or otherwise with respect to the Bank Obligations, or any acceptance of security
for, or guaranties  of, any of the Bank  Obligations or Loan  Documents,  or any
surrender,  release, exchange,  impairment or alteration of any such security or
guaranties  including  without  limitation  the  failing  to  perfect a security
interest  in any  such  security  or  abstaining  from  taking  advantage  or of
realizing  upon  any  guaranties  or upon  any  security  interest  in any  such
security;  (c) any default by any Borrower  under, or any lack of due execution,
invalidity or  unenforceability  of, or any irregularity or other defect in, any
of the Loan  Documents;  (d) any waiver by the Banks or any other  Person of any
required  performance  or otherwise of any condition  precedent or waiver of any
requirement  imposed by any of the Loan  Documents,  any guaranties or otherwise
with respect to the Bank  Obligations;  (e) any exercise or  non-exercise of any
right,  remedy,  power or privilege  in respect of this  Agreement or any of the
other Loan Documents;  (f) any sale, lease, transfer or other disposition of the
assets of any Borrower or any  consolidation  or merger of any Borrower  with or
into  any  other  Person,  corporation,  or  entity,  or any  transfer  or other
disposition  by any Borrower or any other holder of any shares of Capital  Stock
of any  Borrower;  (g) any  bankruptcy,  insolvency,  reorganization  or similar
proceedings involving or affecting any Borrower; (h) the release or discharge of
any Borrower from the performance or observance of any agreement, covenant, term
or condition  under any of the Bank  Obligations or contained in any of the Loan
Documents  by  operation  of law;  or (i) any other  cause  whether  similar  or
dissimilar  to the  foregoing  which,  in the absence of this  provision,  would
release, affect or impair the obligations,  covenants,  agreements and duties of
any Borrower hereunder,  including without limitation any act or omission by the
Agent,  or the Bank or any other any Person  which  increases  the scope of such
Borrower's risk; and in each case described in this paragraph whether or not any
Borrower shall have notice or knowledge of any of the  foregoing,  each of which
is specifically waived by each Borrower. Each Borrower warrants to the Agent and
the Banks that it has  adequate  means to obtain  from each other  Borrower on a
continuing  basis  information  concerning  the  financial  condition  and other
matters with respect to the Borrowers and that it is not relying on the Agent or
the Banks to provide such information either now or in the future.

     10.19 Waivers, Etc. Each Borrower unconditionally waives: (a) notice of any
of the matters  referred to in Section 10.18 above; (b) all notices which may be
required  by statute,  rule or law or  otherwise  to preserve  any rights of the
Agent or the Banks including,  without limitation,  presentment to and demand of
payment or performance  from the other  Borrowers and protect for non-payment or
dishonor;  (c) any right to the exercise by the Agent or the Banks of any right,
remedy, power or privilege in connection with any of the Loan Documents; (d) any
requirement  that the  Agent or the  Banks in the  event of any  default  by any
Borrower,  first make  demand  upon or seek to enforce  remedies  against,  such
Borrower or any other  Borrower  before  demanding  payment  under or seeking to
enforce this Agreement  against any other  Borrower;  (f) any right to notice of
the  disposition  of any security which the Agent or the Banks may hold from any
Borrower or otherwise and any right to object to the  commercial  reasonableness
of the  disposition  of any such  security;  and (g) all errors and omissions in
connection  with the  Agent's  or any Bank's  administration  of any of the Bank
Obligations,  any of the Loan  Documents,  or any other act or  omission  of the
Agent or any Bank which changes the scope of the  Borrower's  risk,  except as a



                                      E-105

<PAGE>


result of the gross  negligence or willful  misconduct of the Agent or any Bank.
The  obligations  of each  Borrower  hereunder  shall be  complete  and  binding
forthwith  upon the  execution  of this  Agreement  and subject to no  condition
whatsoever, precedent or otherwise, and notice of acceptance hereof or action in
reliance hereon shall not be required.

     10.20 Confidentiality.  The Banks and the Agent shall hold all confidential
information  obtained  pursuant to the  requirements of this Agreement which has
been  identified  as such by any  Borrower in  accordance  with their  customary
procedures  for  handling  confidential   information  of  this  nature  and  in
accordance  with  safe and  sound  banking  practices  and in any event may make
disclosure to its examiners,  affiliates,  outside  auditors,  counsel and other
professional  advisors  in  connection  with  this  Agreement  or as  reasonably
required by any bona fide  transferee  or  participant  in  connection  with the
contemplated  transfer  of any Note or  participation  therein or as required or
requested by any governmental  agency or  representative  thereof or pursuant to
legal process.  Without limiting the foregoing,  it is expressly understood that
such confidential  information shall not include  information which, at the time
of disclosure is in the public domain or, which after  disclosure,  becomes part
of the public  domain or  information  which any Bank or the Agent had  obtained
prior to the time of disclosure  and  identification  by any Borrower under this
Section  10.20,  or  information  received by any Bank or the Agent from a third
party. Nothing in this Section 10.20 or otherwise shall prohibit any Bank or the
Agent from  disclosing  any  confidential  information to the other Banks or the
Agent or render any of them liable in connection with any such disclosure.

Memorandum,  each a  "Memorandum")  including  or  incorporating  by reference a
description  of the terms of the  Securities,  the terms of the  offering  and a
description of the Company.  As used herein, the term "Memorandum" shall include
in each  case  the  documents  incorporated  by  reference  therein.  The  terms

     environmental  safety  or  similar  law  or  regulation  applicable  to its
     business  relating  to the  protection  of human  health  and  safety,  the
     environment  or  hazardous or toxic  substances  or wastes,  pollutants  or
     contaminants  ("Environmental Laws"), lacks any permits,  licenses or other
     approvals  required  of them under  applicable  Environmental  Laws to own,

     in the manner described in the Final Memorandum, is violating any terms and
     conditions  of any such  permit,  license or approval or has  permitted  to
     occur any event that allows,  or after notice or lapse of time would allow,
     revocation or termination of any such permit, license or approval or result
     in any other  impairment  of their  rights  thereunder,  which in each case
     would have a material  adverse effect on the Company and its  subsidiaries,
     taken as a whole.

          (t) The  Company  and each of its  subsidiaries  maintain  a system of
     internal  accounting  controls  sufficient to provide reasonable  assurance
     that (1) transactions are executed in accordance with management's  general
     or specific  authorizations;  (2) transactions are recorded as necessary to
     permit  preparation  of financial  statements in conformity  with generally
     accepted accounting  principles and to maintain asset  accountability;  (3)
     access to assets is permitted only in accordance with management's  general
     or specific  authorization;  and (4) the recorded accountability for assets
     is  compared  with  the  existing   assets  at  reasonable   intervals  and
     appropriate action is taken with respect to any differences.

     registrations, trade names, copyrights, licenses, inventions, trade secrets
     and rights  described in the Final Memorandum as being owned by them or any
     of them or necessary for the conduct of their  respective  businesses,  and
     the Company is not aware of any claim to the  contrary or any  challenge by
     any other  person to the rights of the  Company and its  subsidiaries  with
     respect to the foregoing.

          (w) The Company and its  subsidiaries  are insured by the  insurers of
     recognized  financial  responsibility  against such losses and risks and in
     such amounts as are prudent and  customary in the  businesses in which they
     are  engaged;  neither  the Company  nor any of its  subsidiaries  has been
     refused  any  insurance  coverage  sought or applied  for;  and neither the
     Company nor any of its  subsidiaries has any reason to believe that it will
     not be able to renew  its  existing  insurance  coverage  as and when  such
     coverage expires or to obtain similar coverage from similar insurers as may
     be  necessary  to  continue  its  business  at a cost that would not have a
     material  adverse  effect on the Company and its  subsidiaries,  taken as a
     whole, except as described in the Final Memorandum.

          (x)  The  Company  has  reviewed  its   operations  and  that  of  its
     subsidiaries  to evaluate the extent to which the business or operations of
     the  Company or any of its  subsidiaries  will be affected by the Year 2000
     Problem (that is, any significant  risk that computer  hardware or software
     applications used by the Company and its subsidiaries will not, in the case
     of dates or time periods  occurring  after  December 31, 1999,  function at
     least as  effectively  as in the case of  dates or time  periods  occurring
     prior to January 1, 2000); as a result of such review,  (1) the Company has
     no reason to believe,  and does not believe,  that (A) there are any issues
     related to the Company's preparedness to address the Year 2000 Problem that
     are of a  character  required to be  described  or referred to in the Final



                                      E-116

     Memorandum which have not been accurately described in the Final Memorandum
     and (B) the Year 2000  Problem will have a material  adverse  effect on the
     condition,  financial  or  otherwise,  or  on  the  earnings,  business  or
     operations of the Company and its subsidiaries, taken as a whole, or result
     in any material loss or interference with the business or operations of the
     Company  and its  subsidiaries,  taken  as a  whole;  and  (2) the  Company
     reasonably  believes,  after  due  inquiry,  that the  suppliers,  vendors,
     customers or other material third parties used or served by the Company and
     such subsidiaries are addressing or will address the Year 2000 Problem in a
     timely manner, except to the extent that a failure to address the Year 2000
     Problem by any supplier, vendor, customer or material third party would not
     have a material adverse effect on the condition, financial or otherwise, or
     on  the   earnings,   business  or   operations  of  the  Company  and  its
     subsidiaries, taken as a whole.

          (y) All  indebtedness  of the Company and the Guarantors  that will be
     repaid with the  proceeds of the issuance  and sale of the  Securities  was
     incurred,  and the  indebtedness  represented  by the  Securities  is being
     incurred, for proper purposes and in good faith and each of the Company and
     the Guarantors was, at the time of the incurrence of such indebtedness that
     will  be  repaid  with  the  proceeds  of  the  issuance  and  sale  of the
     Securities,  and will be on the Closing  Date (after  giving  effect to the
     application of the proceeds from the issuance of the  Securities)  solvent,
     and had at the time of the  incurrence  of such  indebtedness  that will be
     repaid with the  proceeds of the issuance  and sale of the  Securities  and
     will have on the Closing Date (after  giving effect to the  application  of
     the proceeds from the issuance of the  Securities)  sufficient  capital for
     carrying  on  their  respective  business  and  were,  at the  time  of the
     incurrence  of such  indebtedness  that will be repaid with the proceeds of
     the  issuance  and sale of the  Securities  and will be on the Closing Date
     (after giving effect to the  application  of the proceeds from the issuance
     of the Securities), able to pay their respective debts as they mature.

          (z) The Company is not,  and after  giving  effect to the offering and
     sale of the  Securities  and the  application  of the  proceeds  thereof as
     described in the Final Memorandum,  will not be an "investment  company" as
     such term is defined in the Investment Company Act of 1940, as amended.

          (aa) Neither the Company nor any  affiliate (as defined in Rule 501(b)
     of Regulation D under the Securities  Act, an  "Affiliate")  of the Company
     has directly,  or through any agent, (i) sold, offered for sale,  solicited
     offers to buy or  otherwise  negotiated  in respect  of, any  security  (as
     defined in the Securities Act) which is or will be integrated with the sale
     of the Securities in a manner that would require the registration under the
     Securities  Act of the  Securities  or (ii)  engaged in any form of general
     solicitation or general  advertising in connection with the offering of the
     Securities,  (as those terms are used in Regulation D under the  Securities
     Act) or in any manner  involving  a public  offering  within the meaning of
     Section 4(2) of the Securities Act.

          (bb) None of the Company,  its  Affiliates or any person acting on its
     or their behalf has engaged or will engage in any directed  selling efforts
     (within the meaning of Regulation S) with respect to the Securities and the
     Company and its  Affiliates  and any person  acting on its or their  behalf
     have complied and will comply with the offering restrictions requirement of
     Regulation  S, except no  representation,  warranty or agreement is made by
     the Company in this paragraph with respect to the Placement Agents.

          (cc) It is not  necessary  in  connection  with  the  offer,  sale and
     delivery  of  the  Securities  to  the  Placement   Agents  in  the  manner
     contemplated   by  this  Agreement  to  register  the  Securities  and  the
     Subsidiary  Guarantees under the Securities Act or to qualify the Indenture
     under the Trust Indenture Act of 1939, as amended.

     does it  require  any  consent,  approval,  authorization  or order  of, or
     qualification  with, any governmental body or agency. The issuance and sale
     of the Series A  Preferred  Stock and the Series B  Preferred  Stock by the
     Company does not require the consent,  or approval or  authorization of the
     New York Stock Exchange or the shareholders of the Company.

     2.  Agreements to Sell and Purchase.  The Company  hereby agrees to sell to
the several  Placement  Agents,  and each Placement Agent, upon the basis of the
representations  and warranties herein contained,  but subject to the conditions
hereinafter  stated,  agrees,  severally  and not jointly,  to purchase from the
Company the  respective  principal  amount of Securities set forth in Schedule I
hereto opposite its name at a purchase price of 96.7453% of the principal amount
thereof (the  "Purchase  Price") plus accrued  interest,  if any, to the Closing
Date.

     The Company hereby agrees that, without the prior written consent of Morgan
Stanley  & Co.  Incorporated  on behalf of the  Placement  Agents,  it will not,
during the period  beginning on the date hereof and  continuing to and including
the Closing Date, offer, sell, contract to sell or otherwise dispose of any debt
of the Company or warrants to purchase debt of the Company substantially similar
to the Securities (other than the sale of the Securities under this Agreement).

     3. Terms of  Offering.  You have  advised  the Company  that the  Placement
Agents will make an offering of the Securities purchased by the Placement Agents
hereunder  on the  terms to be set  forth in the  Final  Memorandum,  as soon as
practicable  after  this  Agreement  is  entered  into  as in your  judgment  is
advisable.

     4. Payment and Delivery.  Payment for the  Securities  shall be made to the
Company in Federal or other funds immediately available in New York City against
delivery of such Securities for the respective accounts of the several Placement
Agents at 10:00 a.m.,  New York City time,  on April 29, 1999,  or at such other
time on the same or such other  date,  not later  than May 6, 1999,  as shall be
designated in writing by you. The time and date of such payment are  hereinafter
referred to as the "Closing Date."

     Certificates for the Securities shall be in definitive form or global form,
as specified by you, and registered in such names and in such  denominations  as
you shall  request in writing not later than one full  business day prior to the
Closing Date. The  certificates  evidencing the Securities shall be delivered to
you on the Closing  Date for the  respective  accounts of the several  Placement
Agents,  with any transfer taxes payable in connection  with the transfer of the
Securities to the Placement  Agents duly paid,  against  payment of the Purchase
Price  therefor  plus  accrued  interest,  if any,  to the date of  payment  and
delivery.

     5. Conditions to the Placement Agents' Obligations. The several obligations
of the  Placement  Agents to purchase and pay for the  Securities on the Closing
Date are subject to the following conditions:

               (i) there shall not have occurred any downgrading,  nor shall any
          notice have been given of any intended or potential  downgrading or of
          any review for a possible  change that does not indicate the direction
          of the possible  change,  in the rating  accorded any of the Company's
          securities or in the rating outlook for the Company by any "nationally
          recognized  statistical rating  organization," as such term is defined
          for purposes of Rule 436(g)(2) under the Securities Act; and

               (ii) there shall not have occurred any change, or any development

          and its  subsidiaries,  taken as a whole,  from  that set forth in the
          Final Memorandum  (exclusive of any amendments or supplements  thereto
          subsequent to the date of this Agreement)  that, in your judgment,  is
          material   and   adverse   and  that  makes  it,  in  your   judgment,
          impracticable  to market the Securities on the terms and in the manner
          contemplated in the Final Memorandum.

          (b) The  Placement  Agents  shall have  received on the Closing Date a

     the Company and each of the Guarantors,  to the effect set forth in Section
     5(a)(i) and to the effect that the  representations  and  warranties of the
     Company and the Guarantors contained in this Agreement are true and correct
     as of the  Closing  Date and  that  the  Company  and the  Guarantors  have
     complied with all of the  agreements and satisfied all of the conditions on
     their part to be performed or satisfied  hereunder on or before the Closing
     Date.

     The officers  signing and delivering  such  certificates  may rely upon the
best of his or her knowledge as to proceedings threatened.

          (c) The  Placement  Agents shall have  received on the Closing Date an
     opinion of Locke  Liddell & Sapp LLP,  outside  counsel for the Company and
     the Guarantors,  dated the Closing Date, to the effect set forth in Exhibit

     the Company and the Guarantors and shall so state therein.

          (d) The  Placement  Agents shall have  received on the Closing Date an
     opinion of Baker & Botts,  L.L.P.,  counsel for the Placement Agents, dated
     the Closing Date, to the effect set forth in Exhibit B.

     hereof and the Closing Date a letter,  dated the date hereof or the Closing
     Date,  as the  case  may be,  in form  and  substance  satisfactory  to the
     Placement Agents, from Arthur Andersen LLP, independent public accountants,
     containing  statements and information of the type  ordinarily  included in
     accountants'   "comfort  letters"  to  underwriters  with  respect  to  the
     financial  statements  and certain  financial  information  contained in or
     incorporated  by reference  into the Final  Memorandum;  provided  that the
     letter delivered on the Closing Date shall use a "cut-off date" not earlier
     than the date hereof.

          (f) The Placement Agents shall have received a counterpart,  conformed
     as  executed,  of the  Indenture  which shall have been entered into by the
     Company, the Guarantors and the Trustee.

          (g)  The  Company  and  the   Guarantors   shall  have   executed  the
     Registration  Rights Agreement and the Placement Agents shall have received

          (h) The  sale by the  Company  of  1,948,001  shares  of its  Series A
     preferred Stock and 1,051,999 shares of its Series B preferred Stock for an
     aggregate  purchase price of $30,000,000  shall have been consummated prior
     to or concurrently with the sale by the Company of the Securities  pursuant
     to this Agreement.

     6. Covenants of the Company. In further  consideration of the agreements of
the Placement Agents contained in this Agreement, the Company and the Guarantors
covenant with each Placement Agent as follows:

          (a) To furnish to you in New York City, without charge, prior to 10:00
     a.m.  New York City time on the business  day next  succeeding  the date of

     you a copy of each such proposed amendment or supplement and not to use any
     such proposed amendment or supplement to which you reasonably object.

     on which  all of the  Securities  shall  have  been  sold by the  Placement
     Agents, any event shall occur or condition exist as a result of which it is
     necessary to amend or supplement the Final  Memorandum in order to make the
     statements  therein,  in the  light of the  circumstances  when  the  Final
     Memorandum  is  delivered  to a purchaser,  not  misleading,  or if, in the
     opinion of the Placement Agents, it is necessary to amend or supplement the
     Final  Memorandum to comply with applicable  law,  forthwith to prepare and
     furnish, at its own expense, to the Placement Agents,  either amendments or
     supplements  to the Final  Memorandum  so that the  statements in the Final
     Memorandum  as so amended  or  supplemented  will not,  in the light of the
     circumstances  when the Final  Memorandum  is delivered to a purchaser,  be
     misleading  or so that the Final  Memorandum,  as amended or  supplemented,
     will comply with applicable law.

          (d) To endeavor to qualify the Securities for offer and sale under the

     request,  provided  that in no event  shall the  Company  be  obligated  to
     qualify to do business in any jurisdiction where it is not now so qualified
     or to take any  action  which  would  subject  it to  service of process in
     suits,  other  than  those  arising  out of the  offering  or  sale  of the
     Securities, in any jurisdiction where it is not now so subject.

          (e) Whether or not the transactions contemplated in this Agreement are
     consummated or this Agreement is terminated, to pay or cause to be paid all
     expenses  incident  to the  performance  of their  obligations  under  this

     to the Placement Agents, in the quantities herein above specified, (ii) all

          (h) While any of the Securities remain "restricted  securities" within
     the meaning of the Securities Act, to make available,  upon request, to any
     seller of such  Securities  the  information  specified in Rule  144A(d)(4)
     under the Securities  Act, unless the Company is then subject to Section 13

     Inc. relating to trading in the PORTAL Market.

          (j) None of the Company, its Affiliates or any person acting on its or

Agent,  severally and not jointly,  represents  and warrants that such Placement
Agent is a  qualified  institutional  buyer as  defined  in Rule 144A  under the
Securities  Act (a "QIB").  Each  Placement  Agent,  severally  and not jointly,
agrees  with the Company  that (i) it will not  solicit  offers for, or offer or
sell, such Securities by any form of general solicitation or general advertising
(as those terms are used in  Regulation  D under the  Securities  Act) or in any
manner  involving a public  offering  within the meaning of Section  4(2) of the
Securities  Act and (ii) it will solicit offers for such  Securities  only from,
and will offer such Securities  only to, persons that it reasonably  believes to
be (A) in the case of offers inside the United States,  QIBs and (B) in the case
of offers  outside  the  United  States,  to  persons  other  than U.S.  persons
("foreign  purchasers,"  which term shall include dealers or other  professional
fiduciaries  in the United  States acting on a  discretionary  basis for foreign
beneficial owners (other than an estate or trust)) in reliance upon Regulation S
under the Securities Act that, in each case, in purchasing  such  Securities are
deemed to have  represented and agreed as provided in the Final Memorandum under
the caption "Transfer Restrictions".

     (b) Each Placement Agent, severally and not jointly, represents,  warrants,
and agrees with respect to offers and sales outside the United States that:

          (i) such Placement Agent  understands  that no action has been or will
     be taken in any  jurisdiction  by the  Company  that would  permit a public
     offering  of the  Securities,  or  possession  or  distribution  of  either
     Memorandum  or any other  offering or  publicity  material  relating to the
     Securities, in any country or jurisdiction where action for that purpose is
     required;

          (ii) such  Placement  Agent will comply with all  applicable  laws and
     regulations in each  jurisdiction  in which it acquires,  offers,  sells or
     delivers  Securities  or  has  in  its  possession  or  distributes  either
     Memorandum or any such other material, in all cases at its own expense;

          (iii) the Securities have not been registered under the Securities Act
     and may not be offered or sold  within the United  States or to, or for the
     account or benefit of, U.S.  persons except in accordance with Rule 144A or
     Regulation S under the Securities Act or pursuant to another exemption from
     the registration requirements of the Securities Act;

          (iv) such  Placement  Agent has offered the  Securities and will offer
     and sell the Securities (A) as part of their  distribution  at any time and
     (B)  otherwise  until 40 days  after the later of the  commencement  of the
     offering  and  the  Closing  Date,  only in  accordance  with  Rule  903 of
     Regulation  S or as  otherwise  permitted  in  Section  7(a);  accordingly,
     neither such Placement  Agent, its Affiliates nor any persons acting on its
     or their behalf have engaged or will engage in any directed selling efforts
     (within the meaning of  Regulation S) with respect to the  Securities,  and
     any such Placement Agent, its Affiliates and any such persons have complied
     and will comply with the offering restrictions requirement of Regulation S;

          (v) such  Placement  Agent  has (A) not  offered  or sold and will not
     offer or sell any  Securities  to persons in the United  Kingdom  except to
     persons  whose  ordinary  activities  involve them in  acquiring,  holding,
     managing  or  disposing  of  investments  (as  principal  or agent) for the
     purposes of their businesses or otherwise in  circumstances  which have not
     resulted  and will not  result  in an offer  to the  public  in the  United
     Kingdom  within the meaning of the Public Offers of Securities  Regulations
     1995 or the Financial  Services Act 1986; (B) complied and will comply with
     all applicable  provisions of the Financial  Services Act 1986 with respect
     to anything done by it in relation to the  Securities in, from or otherwise
     involving  the United  Kingdom;  and (C) only  issued or passed on and will
     only issue or pass on in the United Kingdom any document  received by it in
     connection  with the issue of the  Securities  to a person who is of a kind



                                      E-122

<PAGE>



     described in Article 11(3) of the Financial  Services Act 1986  (Investment
     Advertisements) (Exemptions) Order 1996 (as amended) or is a person to whom
     such document may otherwise lawfully be issued or passed on;

          (vi) such Placement  Agent  understands  that the Securities  have not
     been and will not be registered  under the  Securities  and Exchange Law of
     Japan,  and  represents  that it has not offered or sold, and agrees not to
     offer or sell,  directly or indirectly,  any Securities in Japan or for the
     account of any resident  thereof except  pursuant to any exemption from the
     registration  requirements  of the Securities and Exchange Law of Japan and
     otherwise in compliance with applicable provisions of Japanese law; and

          (vii) such Placement Agent agrees that, at or prior to confirmation of
     sales of the Securities,  it will have sent to each distributor,  dealer or
     person  receiving  a selling  concession,  fee or other  remuneration  that
     purchases Securities from it during the restricted period a confirmation or
     notice to substantially the following effect:

          "The Securities covered hereby have not been registered under the U.S.
     Securities  Act of 1933 (the  "Securities  Act") and may not be offered and
     sold within the United States or to, or for the account or benefit of, U.S.
     persons  (i) as part of their  distribution  at any time or (ii)  otherwise
     until 40 days after the later of the  commencement  of the offering and the
     closing  date,  except in either case in accordance  with  Regulation S (or
     Rule 144A if available) under the Securities Act. Terms used above have the
     meaning given to them by Regulation S."

Terms used in this Section 7(b) have the meanings given to them by Regulation S.

     8. Indemnity and Contribution.  (a) The Company and the Guarantors, jointly
and  severally,  agree to indemnify and hold harmless each  Placement  Agent and
each person,  if any, who  controls  any  Placement  Agent within the meaning of
either  Section 15 of the  Securities Act or Section 20 of the Exchange Act from
and against  any and all losses,  claims,  damages and  liabilities  (including,
without  limitation,   any  legal  or  other  expenses  reasonably  incurred  in
connection with defending or  investigating  any such action or claim) caused by
any untrue statement or alleged untrue statement of a material fact contained in
either  Memorandum  (as  amended  or  supplemented  if the  Company  shall  have
furnished any amendments or supplements  thereto),  or caused by any omission or
alleged  omission  to  state  therein  a  material  fact  necessary  to make the
statements therein in the light of the circumstances  under which they were made
not misleading,  except insofar as such losses,  claims,  damages or liabilities
are caused by any such untrue  statement or omission or alleged untrue statement
or omission based upon information  relating to any Placement Agent furnished to
the Company in writing by such  Placement  Agent  through you  expressly for use
therein.

     (b) Each Placement  Agent agrees,  severally and not jointly,  to indemnify
and hold harmless the Company, the Guarantors, their directors, its officers and
each  person,  if any,  who  controls  the Company or any  Guarantor  within the
meaning of either Section 15 of the Securities Act or Section 20 of the Exchange
Act to the same  extent as the  foregoing  indemnity  from the  Company  and the
Guarantors  to such  Placement  Agent,  but only with  reference to  information
relating to such  Placement  Agent  furnished  to the Company in writing by such
Placement  Agent  through  you  expressly  for use in either  Memorandum  or any
amendments or supplements thereto.

     (c) In case any proceeding (including any governmental investigation) shall
be instituted  involving any person in respect of which  indemnity may be sought
pursuant to Section 8(a) or 8(b),  such person (the  "indemnified  party") shall
promptly  notify the  person  against  whom such  indemnity  may be sought  (the
"indemnifying party") in writing and the indemnifying party, upon request of the



                                      E-123

<PAGE>



indemnified  party,   shall  retain  counsel  reasonably   satisfactory  to  the
indemnified  party  to  represent  the  indemnified  party  and any  others  the
indemnifying  party may designate in such  proceeding and shall pay the fees and
disbursements  of  such  counsel  related  to  such  proceeding.   In  any  such
proceeding,  any  indemnified  party  shall  have the  right to  retain  its own
counsel,  but the fees and expenses of such  counsel  shall be at the expense of
such  indemnified  party unless (i) the  indemnifying  party and the indemnified
party shall have  mutually  agreed to the  retention of such counsel or (ii) the
named parties to any such proceeding  (including any impleaded  parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel  would be  inappropriate  due to actual or potential
differing  interests between them. It is understood that the indemnifying  party
shall  not,  in  respect  of the  legal  expenses  of any  indemnified  party in
connection with any proceeding or related  proceedings in the same jurisdiction,
be liable for the fees and expenses of more than one separate  firm (in addition
to any local  counsel) for all such  indemnified  parties and that all such fees
and  expenses  shall be  reimbursed  as they are  incurred.  Such firm  shall be
designated  in  writing  by Morgan  Stanley & Co.  Incorporated,  in the case of
parties indemnified pursuant to Section 8(a), and by the Company, in the case of
parties  indemnified  pursuant to Section 8(b). The indemnifying party shall not
be liable for any  settlement  of any  proceeding  effected  without its written
consent,  but if settled with such  consent or if there be a final  judgment for
the plaintiff,  the indemnifying party agrees to indemnify the indemnified party
from and against any loss or liability by reason of such settlement or judgment.
Notwithstanding  the foregoing  sentence,  if at any time an  indemnified  party
shall have requested an indemnifying  party to reimburse the  indemnified  party
for fees and  expenses  of  counsel  as  contemplated  by the  second  and third
sentences  of this  paragraph,  the  indemnifying  party agrees that it shall be
liable for any settlement of any proceeding effected without its written consent
if (i) such  settlement  is entered into more than 30 days after receipt by such
indemnifying  party of the aforesaid  request and (ii) such  indemnifying  party
shall not have reimbursed the indemnified  party in accordance with such request
prior to the date of such settlement.  No indemnifying party shall,  without the
prior written  consent of the  indemnified  party,  effect any settlement of any
pending or threatened proceeding in respect of which any indemnified party is or
could have been a party and indemnity  could have been sought  hereunder by such
indemnified party, unless such settlement  includes an unconditional  release of
such indemnified  party from all liability on claims that are the subject matter
of such proceeding.

     (d) To the extent the indemnification  provided for in Section 8(a) or 8(b)
is unavailable to an indemnified party or insufficient in respect of any losses,
claims, damages or liabilities referred to therein, then each indemnifying party
under such paragraph, in lieu of indemnifying such indemnified party thereunder,
shall  contribute to the amount paid or payable by such  indemnified  party as a
result of such losses,  claims, damages or liabilities (i) in such proportion as
is appropriate to reflect the relative  benefits received by the Company and the
Guarantors on the one hand and the  Placement  Agents on the other hand from the
offering of the Securities or (ii) if the allocation  provided by clause 8(d)(i)
above is not permitted by applicable  law, in such  proportion as is appropriate
to reflect not only the relative  benefits  referred to in clause  8(d)(i) above
but also the relative  fault of the Company and the  Guarantors  on the one hand
and of the Placement  Agents on the other hand in connection with the statements
or omissions that resulted in such losses,  claims,  damages or liabilities,  as
well as any other  relevant  equitable  considerations.  The  relative  benefits
received  by the Company and the  Guarantors  on the one hand and the  Placement
Agents on the other hand in connection with the offering of the Securities shall
be deemed to be in the same respective  proportions as the net proceeds from the
offering of the Securities  (before deducting  expenses) received by the Company
and the  Guarantors  and the total  discounts  and  commissions  received by the
Placement Agents, in each case as set forth in the Final Memorandum, bear to the
aggregate  offering price of the  Securities.  The relative fault of the Company
and the Guarantors on the one hand and of the Placement Agents on the other hand
shall be determined  by reference to, among other things,  whether the untrue or
alleged untrue  statement of a material fact or the omission or alleged omission
to state a material fact relates to information  supplied by the Company and the
Guarantors  or by  the  Placement  Agents  and  the  parties'  relative  intent,
knowledge,  access to  information  and  opportunity  to correct or prevent such


                                      E-124

<PAGE>


statement  or  omission.   The  Placement  Agents'  respective   obligations  to
contribute  pursuant  to  this  Section  8 are  several  in  proportion  to  the
respective principal amount of Securities they have purchased hereunder, and not
joint.

     (e) The Company,  the  Guarantors  and the  Placement  Agents agree that it
would not be just or equitable if  contribution  pursuant to this Section 8 were
determined by pro rata allocation  (even if the Placement Agents were treated as
one entity for such purpose) or by any other method of allocation  that does not
take account of the equitable  considerations  referred to in Section 8(d).  The
amount  paid or  payable  by an  indemnified  party as a result  of the  losses,
claims,  damages and liabilities  referred to in Section 8(d) shall be deemed to
include, subject to the limitations set forth above, any legal or other expenses
reasonably  incurred by such indemnified party in connection with  investigating
or defending any such action or claim.  Notwithstanding  the  provisions of this
Section 8, no  Placement  Agent shall be required  to  contribute  any amount in
excess of the amount by which the total price at which the Securities  resold by
it in the initial placement of such Securities were offered to investors exceeds
the amount of any damages that such Placement  Agent 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 remedies provided for in this Section 8 are not exclusive
and shall not limit any rights or remedies  which may  otherwise be available to
any indemnified party at law or in equity.

     (f) The indemnity and contribution  provisions  contained in this Section 8
and  the  representations,  warranties  and  other  statements  of  the  Company
contained in this Agreement shall remain  operative and in full force and effect
regardless of (i) any termination of this Agreement, (ii) any investigation made
by or on behalf of any Placement  Agent or any person  controlling any Placement
Agent or by or on behalf of the Company,  or any  Guarantor,  their  officers or
directors  or any person  controlling  the  Company or any  Guarantor  and (iii)
acceptance of and payment for any of the Securities.

     9.  Termination.  This Agreement  shall be subject to termination by notice
given by you to the  Company,  if (a) after the  execution  and delivery of this
Agreement  and prior to the Closing Date (i) trading  generally  shall have been
suspended  or  materially  limited  on or by, as the case may be, any of the New
York Stock Exchange,  the American Stock Exchange,  the National  Association of
Securities  Dealers,  Inc., the Chicago Board of Options  Exchange,  the Chicago
Mercantile  Exchange  or  the  Chicago  Board  of  Trade,  (ii)  trading  of any
securities  of the Company  shall have been  suspended on any exchange or in any
over-the-counter  market,  (iii) a  general  moratorium  on  commercial  banking
activities  in New York shall have been  declared by either  Federal or New York
State  authorities  or (iv) there shall have occurred any outbreak or escalation
of  hostilities  or any change in  financial  markets or any  calamity or crisis
that,  in your  judgment,  is material and adverse and (b) in the case of any of
the events specified in clauses 9(a)(i) through 9(a)(iv),  such event, singly or
together with any other such event, makes it, in your judgment, impracticable to
market the Securities on the terms and in the manner  contemplated  in the Final
Memorandum.

     10. Effectiveness; Defaulting Placement Agents. This Agreement shall become
effective upon the execution and delivery hereof by the parties hereto.

     If, on the Closing Date, any one or more of the Placement Agents shall fail
or refuse  to  purchase  Securities  that it or they  have  agreed  to  purchase
hereunder on such date, and the aggregate  principal  amount of Securities which
such defaulting Placement Agent or Placement Agents agreed but failed or refused
to purchase is not more than  one-tenth  of the  aggregate  principal  amount of
Securities  to be purchased on such date,  the other  Placement  Agents shall be
obligated  severally in the proportions  that the principal amount of Securities
set forth opposite their  respective  names in Schedule I bears to the aggregate
principal  amount  of  Securities  set  forth  opposite  the  names  of all such
non-defaulting  Placement  Agents,  or in  such  other  proportions  as you  may
specify,  to purchase the Securities  which such  defaulting  Placement Agent or
Placement Agents agreed but failed or refused to purchase on such date; provided



                                      E-125

<PAGE>


that in no event shall the  principal  amount of  Securities  that any Placement
Agent has agreed to purchase pursuant to this Agreement be increased pursuant to
this Section 10 by an amount in excess of one-ninth of such principal  amount of
Securities  without  the written  consent of such  Placement  Agent.  If, on the
Closing Date any  Placement  Agent or  Placement  Agents shall fail or refuse to
purchase  Securities which it or they have agreed to purchase  hereunder on such
date and the aggregate principal amount of Securities with respect to which such
default  occurs is more than  one-tenth  of the  aggregate  principal  amount of
Securities to be purchased on such date, and  arrangements  satisfactory  to you
and the Company for the purchase of such Securities are not made within 36 hours
after such default, this Agreement shall terminate without liability on the part
of any non-defaulting  Placement Agent or of the Company and the Guarantors.  In
any such case  either you or the Company  shall have the right to  postpone  the
Closing  Date,  but in no event for longer  than seven  days,  in order that the
required  changes,  if any, in the Final Memorandum or in any other documents or
arrangements  may be effected.  Any action taken under this paragraph  shall not
relieve any defaulting  Placement Agent from liability in respect of any default
of such Placement Agent under this Agreement.

     If this Agreement  shall be terminated by the Placement  Agents,  or any of
them,  because  of any  failure  or  refusal  on the part of the  Company or any
Guarantor to comply with the terms or to fulfill any of the  conditions  of this
Agreement,  or if for any reason the Company or any Guarantor shall be unable to
perform its  obligations  under this  Agreement,  the Company and the Guarantors
will  reimburse  the  Placement  Agents  or  such  Placement  Agents  as have so
terminated  this  Agreement  with  respect  to  themselves,  severally,  for all
out-of-pocket  expenses  (including the fees and disbursements of their counsel)
reasonably  incurred by such Placement  Agents in connection with this Agreement
or the offering contemplated hereunder.

     11.   Counterparts.   This  Agreement  may  be  signed  in  any  number  of
counterparts, each of which shall be an original, with the same effect as if the
signatures thereto and hereto were upon the same instrument.

     12.  Applicable  Law. This Agreement  shall be governed by and construed in
accordance with the internal laws of the State of New York.

     13.  Headings.  The  headings of the sections of this  Agreement  have been
inserted for  convenience  of  reference  only and shall not be deemed a part of
this Agreement.

          This Agreement is made pursuant to the Placement Agreement dated April

Company's 11 1/4% Senior Notes due 2007 (the  "Securities").  In order to induce
the Placement Agents to enter into the Placement Agreement,  the Company and the
Guarantors  here agreed to provide to the Placement  Agents and their direct and
indirect  transferees the registration  rights set forth in this Agreement.  The
execution of this  Agreement is a condition to the closing  under the  Placement
Agreement.

          In  consideration  of the  foregoing,  the  parties  hereto  agree  as

          6. Registration Under the 1933 Act.

          (a) To the extent not  prohibited by any  applicable law or applicable
interpretation of the Staff of the SEC, the Company and the Guarantors shall use

and the Guarantors shall commence the Exchange Offer promptly after the Exchange
Offer  Registration  Statement  has been  declared  effective by the SEC and use
their best efforts to have the Exchange Offer consummated not later than 60 days
after such effective  date.  The Company and the  Guarantors  shall commence the
Exchange Offer by mailing the related exchange offer Prospectus and accompanying
documents to each Holder stating,  in addition to such other  disclosures as are
required by applicable law:

<PAGE>



                    (i) that the Exchange  Offer is being made  pursuant to this
          Registration  Rights  Agreement  and that all  Registrable  Securities
          validly tendered will be accepted for exchange;

                    (ii) the dates of acceptance for exchange  (which shall be a
          period  of at least 20  business  days  from the date  such  notice is
          mailed) (the "Exchange Dates");

                    (iii) that any Registrable Security not tendered will remain
          outstanding and continue to accrue  interest,  but will not retain any
          rights under this Registration Rights Agreement;

                    (iv) that Holders  electing to have a  Registrable  Security
          exchanged pursuant to the Exchange Offer will be required to surrender
          such  Registrable  Security,  together  with the  enclosed  letters of
          transmittal,  to the  institution  and at the address  (located in the
          Borough of  Manhattan,  The City of New York)  specified in the notice
          prior to the close of business on the last Exchange Date; and

                    (v) that  Holders  will  be  entitled  to  withdraw   their
          election,  not later than the close of business  on the last  Exchange
          Date, by sending to the institution and at the address (located in the
          Borough of Manhattan,  The City of New York) specified in the notice a
          telegram,  telex,  facsimile  transmission or letter setting forth the
          name of such Holder,  the principal  amount of Registrable  Securities
          delivered for exchange and a statement that such Holder is withdrawing
          his election to have such Registrable Securities exchanged.

                    As soon as  practicable  after the last Exchange  Date,  the
          Company shall:

                    (i) accept for exchange  Registrable  Securities or portions
          thereof  tendered and not validly  withdrawn  pursuant to the Exchange
          Offer; and

                    (ii) deliver,  or cause to be delivered,  to the Trustee for
          cancellation  all  Registrable   Securities  or  portions  thereof  so
          accepted for exchange by the Company and issue,  and cause the Trustee
          to promptly authenticate and mail to each Holder, an Exchange Security
          equal in principal  amount to the principal  amount of the Registrable
          Securities surrendered by such Holder.

The  Company and the  Guarantors  shall use their best  efforts to complete  the
Exchange   Offer  as  provided  above  and  shall  comply  with  the  applicable
requirements  of the  1933  Act,  the  1934 Act and  other  applicable  laws and
regulations in connection with the Exchange Offer.  The Exchange Offer shall not
be  subject  to any  conditions,  other  than that the  Exchange  Offer does not
violate applicable law or any applicable interpretation of the Staff of the SEC.
The Company shall inform the Placement  Agents of the names and addresses of the
Holders to whom the Exchange Offer is made, and the Placement  Agents shall have
the right,  subject to  applicable  law, to contact such  Holders and  otherwise
facilitate the tender of Registrable Securities in the Exchange Offer.

          (b) In the event that (i) the  Company  and the  Guarantors  determine
that the Exchange Offer  Registration  provided for in Section 2(a) above is not
available  or may not be  consummated  as soon as  practicable  after  the  last
Exchange  Date  because  it  would  violate  applicable  law or  the  applicable
interpretations  of the Staff of the SEC, (ii) the Exchange Offer is not for any
other reason  consummated  by October 29, 1999 or (iii) the  Exchange  Offer has
been  completed  and in the  opinion  of  counsel  for the  Placement  Agents  a
Registration  Statement must be filed and a Prospectus  must be delivered by the
Placement  Agents  in  connection  with  any  offering  or sale  of  Registrable
Securities, the Company and the Guarantors shall use their best efforts to cause
to be filed as soon as practicable after such  determination,  date or notice of
such  opinion of counsel  is given to the  Company,  as the case may be, a Shelf
Registration  Statement  providing  for the  sale by the  Holders  of all of the



                                      E-132

<PAGE>


Registrable  Securities and to have such Shelf  Registration  Statement declared
effective by the SEC. In the event the Company and the  Guarantors  are required
to file a  Shelf  Registration  Statement  solely  as a  result  of the  matters
referred  to in clause  (iii) of the  preceding  sentence,  the  Company and the
Guarantors  shall use their best efforts to file and have declared  effective by
the SEC both an Exchange Offer  Registration  Statement pursuant to Section 2(a)
with respect to all Registrable  Securities and a Shelf  Registration  Statement
(which  may  be a  combined  Registration  Statement  with  the  Exchange  Offer
Registration  Statement)  with  respect  to  offers  and  sales  of  Registrable
Securities held by the Placement  Agents after completion of the Exchange Offer.
The Company and the Guarantors agree to use their best efforts to keep the Shelf
Registration Statement continuously effective until the expiration of the period
referred to in Rule 144(k) with respect to the  Registrable  Securities  or such
shorter  period  that  will  terminate  when all of the  Registrable  Securities
covered by the Shelf Registration Statement have been sold pursuant to the Shelf
Registration  Statement.  The  Company  and  the  Guarantors  further  agree  to
supplement or amend the Shelf  Registration  Statement if required by the rules,
regulations  or  instructions  applicable to the  registration  form used by the
Company and the Guarantors for such Shelf Registration  Statement or by the 1933
Act or by any other rules and regulations  thereunder for shelf  registration or
if reasonably requested by a Holder with respect to information relating to such
Holder,  and to use its best  efforts  to cause  any such  amendment  to  become
effective  and such Shelf  Registration  Statement  to become  usable as soon as
thereafter  practicable.  The Company and the Guarantors agree to furnish to the
Holders of  Registrable  Securities  copies of any such  supplement or amendment
promptly after it is used or filed with the SEC.

          (c) The Company shall pay all Registration Expenses in connection with
the  registration  pursuant to Section 2(a) and Section 2(b).  Each Holder shall
pay all  underwriting  discounts and  commissions  and transfer  taxes,  if any,
relating to the sale or  disposition  of such  Holder's  Registrable  Securities
pursuant to the Shelf Registration Statement.

          (d) An Exchange Offer Registration  Statement pursuant to Section 2(a)
hereof or a Shelf  Registration  Statement  pursuant to Section 2(b) hereof will
not be deemed to have become effective unless it has been declared  effective by
the SEC; provided,  however, that, if, after it has been declared effective, the
offering of Registrable Securities pursuant to a Shelf Registration Statement is
interfered  with by any stop order,  injunction or other order or requirement of
the SEC or any other governmental  agency or court, such Registration  Statement
will  be  deemed  not to  have  become  effective  during  the  period  of  such
interference  until the  offering  of  Registrable  Securities  pursuant to such
Registration  Statement may legally  resume.  In the event the Exchange Offer is
not consummated and the Shelf  Registration  Statement is not declared effective
on or prior to October 29, 1999,  the interest  rate on the  Securities  will be
increased by 0.5% per annum until the Exchange Offer is consummated or the Shelf
Registration Statement is declared effective by the SEC.

          (e) Without  limiting the remedies  available to the Placement  Agents
and the Holders, the Company and the Guarantors  acknowledge that any failure by
the Company or any Guarantor to comply with their respective  obligations  under
Section 2(a) and Section 2(b) hereof may result in material  irreparable  injury
to the Placement  Agents or the Holders for which there is no adequate remedy at
law, that it will not be possible to measure damages for such injuries precisely
and that, in the event of any such failure,  the Placement  Agents or any Holder
may obtain such relief as may be required to specifically  enforce the Company's
and the Guarantors' obligations under Section 2(a) and Section 2(b) hereof.

          7. Registration Procedures.

          In connection  with the  obligations of the Company and the Guarantors
with respect to the Registration Statements pursuant to Section 2(a) and Section
2(b) hereof, the Company and the Guarantors shall as expeditiously as possible:

          Registration,  be available for the sale of the Registrable Securities
          by the selling  Holders thereof and (z) shall comply as to form in all
          material  respects with the  requirements  of the applicable  form and

          Section 2 hereof;

                    (b)  prepare  and  file  with the SEC  such  amendments  and
          post-effective  amendments  to each  Registration  Statement as may be
          necessary  to  keep  such  Registration  Statement  effective  for the
          applicable  period and cause each Prospectus to be supplemented by any
          required  prospectus  supplement and, as so supplemented,  to be filed
          pursuant  to Rule 424  under the 1933  Act;  to keep  each  Prospectus
          current  during the period  described  under Section 4(3) and Rule 174
          under the 1933 Act that is  applicable to  transactions  by brokers or
          dealers  with  respect  to  the  Registrable  Securities  or  Exchange

          copies of each Prospectus,  including each preliminary Prospectus, and
          any amendment or supplement  thereto and such other  documents as such
          Holder or Underwriter may reasonably  request,  in order to facilitate
          the public sale or other  disposition of the  Registrable  Securities;
          and  the  Company  and  the  Guarantors  consent  to the  use of  such
          Prospectus and any amendment or supplement  thereto in accordance with
          applicable  law  by  each  of  the  selling   Holders  of  Registrable
          Securities and any such  Underwriters  in connection with the offering
          and sale of the  Registrable  Securities  covered by and in the manner
          described in such Prospectus or any amendment or supplement thereto in
          accordance with applicable law;

                    (d)  use  its  best  efforts  to  register  or  qualify  the
          Registrable  Securities under all applicable state securities or "blue
          sky"  laws  of  such   jurisdictions  as  any  Holder  of  Registrable
          Securities  covered  by  a  Registration  Statement  shall  reasonably
          request in writing by the time the applicable  Registration  Statement
          is declared  effective by the SEC, to  cooperate  with such Holders in

          Association of Securities Dealers,  Inc. and do any and all other acts
          and things  which may be  reasonably  necessary or advisable to enable
          such Holder to consummate the disposition in each such jurisdiction of
          such Registrable Securities owned by such Holder;  provided,  however,
          that  neither  the Company or any  Guarantor  shall be required to (i)
          qualify as a foreign  corporation  or as a dealer in securities in any

          of Registrable Securities, counsel for the Holders and counsel for the
          Placement  Agents  promptly  and, if  requested  by any such Holder or

          Statement has become effective and when any  post-effective  amendment
          thereto has been filed and becomes  effective,  (ii) of any request by
          the  SEC  or  any  state  securities   authority  for  amendments  and
          supplements  to  a  Registration   Statement  and  Prospectus  or  for
          additional  information  after the  Registration  Statement has become

          authority  of  any  stop  order  suspending  the  effectiveness  of  a
          Registration  Statement or the initiation of any  proceedings for that

          the Company or any Guarantor receives any notification with respect to
          the suspension of the qualification of the Registrable  Securities for
          sale in any  jurisdiction or the initiation of any proceeding for such
          purpose,  (v) of the  happening of any event during the period a Shelf
          Registration  Statement is effective which makes any statement made in
          such  Registration  Statement or the related  Prospectus untrue in any
          material  respect or which  requires the making of any changes in such
          Registration  Statement or Prospectus in order to make the  statements
          therein not misleading and (vi) of any determination by the Company or
          any  Guarantor  that  a  post-effective  amendment  to a  Registration
          Statement would be appropriate;

                    (f)make every reasonable  effort to obtain the withdrawal of
          any order suspending the effectiveness of a Registration  Statement at
          the  earliest  possible  moment and provide  immediate  notice to each
          Holder of the withdrawal of any such order;

                    (g) in the  case of a Shelf  Registration,  furnish  to each
          Holder  of  Registrable  Securities,  without  charge,  at  least  one

          enable  such  Registrable  Securities  to  be  in  such  denominations
          (consistent  with the  provisions of the  Indenture) and registered in
          such names as the selling Holders may reasonably  request at least one
          business  day  prior  to  the  closing  of  any  sale  of  Registrable
          Securities;

                    (i) in the case of a Shelf Registration, upon the occurrence
          of any event  contemplated  by Section  3(e)(v)  hereof,  use its best
          efforts  to   prepare   and  file  with  the  SEC  a   supplement   or

          Prospectus or any document  incorporated  therein by reference or file
          any other  required  document so that, as thereafter  delivered to the
          purchasers of the  Registrable  Securities,  such  Prospectus will not
          contain  any untrue  statement  of a material  fact or omit to state a
          material fact  necessary to make the statements  therein,  in light of
          the  circumstances  under which they were made,  not  misleading.  The
          Company and the Guarantors  agree to notify the Holders to suspend use
          of the Prospectus as promptly as  practicable  after the occurrence of
          such an event,  and the  Holders  hereby  agree to suspend  use of the

          Placement  Agents  and  their  counsel  (and,  in the  case of a Shelf
          Registration  Statement,  the Holders and their counsel) and make such
          of the  representatives  of the Company and the Guarantors as shall be
          reasonably requested by the Placement Agents or their counsel (and, in

          any time file or make any amendment to the Registration Statement, any
          Prospectus  or  any  amendment  of  or  supplement  to a  Registration
          Statement or a Prospectus or any document which is to be  incorporated
          by reference into a Registration  Statement or a Prospectus,  of which

          Agents  or their  counsel  (and,  in the case of a Shelf  Registration
          Statement, the Holders or their counsel) shall object;

                    (k) obtain a CUSIP  number for all  Exchange  Securities  or
          Registrable  Securities,  as the  case  may be,  not  later  than  the
          effective date of a Registration Statement;

                    (l)  cause the  Indenture  to be  qualified  under the Trust
          Indenture Act of 1939, as amended (the "TIA"),  in connection with the
          registration of the Exchange Securities or Registrable Securities,  as
          the case may be,  cooperate with the Trustee and the Holders to effect
          such changes to the  Indenture as may be required for the Indenture to
          be so qualified in  accordance  with the terms of the TIA and execute,
          and use its  best  efforts  to  cause  the  Trustee  to  execute,  all
          documents  as may be  required  to effect  such  changes and all other
          forms and  documents  required  to be filed with the SEC to enable the
          Indenture to be so qualified in a timely manner;

          inspection  by a  representative  of the  Holders  of the  Registrable

          designated  by the Holders,  at  reasonable  times and in a reasonable
          manner,  all  financial  and other  records,  pertinent  documents and

          Registration Statement;

                    (n) in the  case  of a  Shelf  Registration,  use  its  best
          efforts  to cause  all  Registrable  Securities  to be  listed  on any
          securities exchange or any automated quotation system on which similar
          securities issued by the Company and the Guarantors are then listed if
          requested  by the  Majority  Holders,  to the extent such  Registrable
          Securities satisfy applicable listing requirements;

                    (o) use its best efforts to cause the Exchange Securities or
          Registrable  Securities,  as the  case  may  be,  to be  rated  by two
          nationally  recognized  statistical rating organizations (as such term
          is defined in Rule 436(g)(2) under the 1933 Act);

                    (p) if  reasonably  requested  by any Holder of  Registrable
          Securities   covered  by  a  Registration   Statement,   (i)  promptly
          incorporate  in a Prospectus  supplement or  post-effective  amendment
          such information with respect to such Holder as such Holder reasonably
          requests to be included  therein and (ii) make all required filings of
          such Prospectus supplement or such post-effective amendment as soon as
          the  Company  has   received   notification   of  the  matters  to  be
          incorporated in such filing; and

                    (q) in the case of a Shelf  Registration,  enter  into  such
          customary  agreements  and take all such other  actions in  connection
          therewith  (including  those requested by the Holders of a majority of
          the  Registrable  Securities  being  sold)  in order  to  expedite  or
          facilitate the disposition of such Registrable  Securities  including,
          but not limited to, an Underwritten  Offering and in such  connection,
          (i) to the extent possible,  make such  representations and warranties
          to the Holders and any  Underwriters  of such  Registrable  Securities
          with  respect to the  business of the  Company  and its  subsidiaries,
          including the Guarantors,  the Registration Statement,  Prospectus and
          documents   incorporated  by  reference  or  deemed   incorporated  by
          reference,  if any, 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  requested,  (ii) obtain  opinions of
          counsel to the Company and the Guarantors (which counsel and opinions,



                                      E-136

<PAGE>


          in form, scope and substance,  shall be reasonably satisfactory to the
          Holders and such Underwriters and their respective  counsel) addressed
          to each selling  Holder and  Underwriter  of  Registrable  Securities,
          covering  the matters  customarily  covered in opinions  requested  in
          underwritten  offerings,  (iii) obtain "cold comfort" letters from the
          independent  certified  public  accountants  of the  Company  and  the
          Guarantors (and, if necessary,  any other certified public  accountant
          of any subsidiary of the Company,  or of any business  acquired by the
          Company or any Guarantor for which financial  statements and financial
          data are or are required to be included in the Registration Statement)
          addressed  to each  selling  Holder  and  Underwriter  of  Registrable
          Securities,  such letters to be in customary form and covering matters
          of  the  type  customarily   covered  in  "cold  comfort"  letters  in
          connection  with  underwritten   offerings,   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 or the  Underwriters,  and which are customarily
          delivered  in  underwritten   offerings,  to  evidence  the  continued
          validity of the  representations and warranties of the Company and the
          Guarantors   made  pursuant  to  clause  (i)  above  and  to  evidence
          compliance with any customary  conditions contained in an underwriting
          agreement.

          In the case of a Shelf  Registration  Statement,  the  Company and the
Guarantors may require each Holder of  Registrable  Securities to furnish to the
Company  and the  Guarantors  such  information  regarding  the  Holder  and the
proposed  distribution  by such  Holder of such  Registrable  Securities  as the
Company and the Guarantors may from time to time reasonably request in writing.

          In the case of a Shelf  Registration  Statement,  each  Holder  agrees
that,  upon  receipt of any notice  from the  Company  or any  Guarantor  of the
happening of any event of the kind  described in Section  3(e)(v)  hereof,  such
Holder will forthwith discontinue disposition of Registrable Securities pursuant
to a  Registration  Statement  until such Holder's  receipt of the copies of the
supplemented or amended Prospectus  contemplated by Section 3(i) hereof, and, if
so  directed by the Company or any  Guarantor,  such Holder will  deliver to the
Company (at its expense) all copies in its possession, other than permanent file
copies  then  in such  Holder's  possession,  of the  Prospectus  covering  such
Registrable  Securities  current at the time of receipt of such  notice.  If the
Company or any Guarantor  shall give any such notice to suspend the  disposition
of Registrable Securities pursuant to a Registration Statement,  the Company and
the Guarantors shall extend the period during which the  Registration  Statement
shall be maintained  effective  pursuant to this Agreement by the number of days
during the period  from and  including  the date of the giving of such notice to
and  including  the date when the  Holders  shall  have  received  copies of the
supplemented or amended Prospectus  necessary to resume such  dispositions.  The
Company and the  Guarantors  may give any such notice only twice  during any 365
day period and any such  suspensions  may not exceed 30 days for each suspension
and there  may not be more than two  suspensions  in effect  during  any 365 day
period.

          The Holders of Registrable  Securities covered by a Shelf Registration
Statement  who  desire  to do so may  sell  such  Registrable  Securities  in an
Underwritten  Offering. In any such Underwritten Offering, the investment banker
or  investment  bankers and manager or managers (the  "Underwriters")  that will
administer  the  offering  will  be  selected  by the  Majority  Holders  of the
Registrable Securities included in such offering.

          8. Participation of Broker-Dealers in Exchange Offer.

          (a) The Staff of the SEC has taken the position that any broker-dealer
that receives  Exchange  Securities for its own account in the Exchange Offer in
exchange for Securities that were acquired by such  broker-dealer as a result of
market-making or other trading  activities (a  "Participating  Broker- Dealer"),
may be deemed to be an "underwriter" within the meaning of the 1933 Act and must
deliver a prospectus meeting the requirements of the 1933 Act in connection with
any resale of such Exchange Securities.


                                      E-137

<PAGE>




          The  Company  and the  Guarantors  understand  that it is the  Staff's
position that if the  Prospectus  contained in the Exchange  Offer  Registration
Statement  includes a plan of  distribution  containing a statement to the above
effect  and the  means by which  Participating  Broker-Dealers  may  resell  the
Exchange  Securities,   without  naming  the  Participating   Broker-Dealers  or
specifying the amount of Exchange  Securities owned by them, such Prospectus may
be  delivered  by  Participating  Broker-Dealers  to  satisfy  their  prospectus
delivery  obligation  under the 1933 Act in connection  with resales of Exchange
Securities for their own accounts, so long as the Prospectus otherwise meets the
requirements of the 1933 Act.

          (b) In light of the above,  notwithstanding  the other  provisions  of
this Agreement, the Company and the Guarantors agree that the provisions of this
Agreement as they relate to a Shelf Registration shall also apply to an Exchange
Offer Registration to the extent, and with such reasonable modifications thereto
as may  be,  reasonably  requested  by the  Placement  Agents  or by one or more
Participating Broker-Dealers,  in each case as provided in clause (ii) below, in
order to expedite or facilitate the  disposition  of any Exchange  Securities by
Participating  Broker-Dealers consistent with the positions of the Staff recited
in Section 4(a) above; provided that:

                    (i) the Company and the Guarantors  shall not be required to
          amend or supplement  the  Prospectus  contained in the Exchange  Offer
          Registration  Statement, as would otherwise be contemplated by Section
          3(i), for a period exceeding 180 days after the last Exchange Date (as
          such period may be extended  pursuant to the penultimate  paragraph of
          Section 3 of this Agreement) and  Participating  Broker-Dealers  shall
          not be  authorized  by the Company and the  Guarantors  to deliver and
          shall not deliver such Prospectus after such period in connection with
          the resales contemplated by this Section 4; and

                    (ii) the  application of the Shelf  Registration  procedures
          set  forth  in  Section  3 of  this  Agreement  to an  Exchange  Offer
          Registration, to the extent not required by the positions of the Staff
          of the SEC or the 1933 Act and the rules and  regulations  thereunder,
          will be in conformity  with the  reasonable  request to the Company by
          the Placement Agents or with the reasonable  request in writing to the
          Company by one or more  broker-dealers  who  certify to the  Placement
          Agents and the Company in writing that they  anticipate that they will
          be  Participating  Broker-Dealers;   and  provided  further  that,  in
          connection with such application of the Shelf Registration  procedures
          set forth in Section 3 to an Exchange Offer Registration,  the Company
          and the Guarantors shall be obligated (x) to deal only with one entity
          representing the Participating  Broker-Dealers,  which shall be Morgan
          Stanley  & Co.  Incorporated  unless  it  elects  not to  act as  such
          representative,  (y) to pay the fees and  expenses of only one counsel
          representing the Participating Broker-Dealers,  which shall be counsel
          to the Placement  Agents unless such counsel  elects not to so act and
          (z) to cause to be delivered only one, if any,  "cold comfort"  letter
          with  respect  to the  Prospectus  in the  form  existing  on the last
          Exchange  Date  and  with  respect  to each  subsequent  amendment  or
          supplement, if any, effected during the period specified in clause (i)
          above.

          (c) The Placement  Agents shall have no liability to the Company,  any
Guarantor or any Holder with respect to any request that it may make pursuant to
Section 4(b) above.

          9. Indemnification and Contribution.

          (a) The Company and the Guarantors  agree,  severally and jointly,  to
indemnify and hold harmless the Placement  Agents,  each Holder and each Person,
if any,  who controls any  Placement  Agent or any Holder  within the meaning of
either  Section 15 of the 1933 Act or  Section  20 of the 1934 Act,  or is under
common  control with, or is  controlled  by, any Placement  Agent or any Holder,
from and against all losses, claims, damages and liabilities (including, without
limitation,  any legal or other  expenses  reasonably  incurred by any Placement



                                      E-138

<PAGE>


Agent,  any Holder or any such  controlling  or affiliated  Person in connection
with defending or  investigating  any such action or claim) caused by any untrue
statement  or alleged  untrue  statement  of a material  fact  contained  in any
Registration  Statement (or any amendment  thereto)  pursuant to which  Exchange
Securities  or  Registrable  Securities  were  registered  under  the 1933  Act,
including all  documents  incorporated  therein by  reference,  or caused by any
omission or alleged  omission to state  therein a material  fact  required to be
stated therein or necessary to make the statements  therein not  misleading,  or
caused by any untrue  statement or alleged  untrue  statement of a material fact
contained in any  Prospectus (as amended or  supplemented  if the Company or any
Guarantor shall have furnished any amendments or supplements thereto), or caused
by any omission or alleged  omission to state therein a material fact  necessary
to make the statements  therein in light of the  circumstances  under which they
were made not  misleading,  except  insofar as such losses,  claims,  damages or
liabilities  are caused by any such  untrue  statement  or  omission  or alleged
untrue  statement or omission based upon  information  relating to the Placement
Agents or any Holder  furnished to the Company or any Guarantor in writing by or
through Morgan Stanley & Co.  Incorporated  or any selling Holder  expressly for
use therein.  In connection with any Underwritten  Offering permitted by Section
3, the Company and the  Guarantors,  severally and jointly,  will also indemnify
the  Underwriters,  if any,  selling  brokers,  dealers and  similar  securities
industry  professionals  participating in the  distribution,  their officers and
directors and each Person who controls  such Persons  (within the meaning of the
1933 Act and the 1934 Act) to the same extent as provided  above with respect to
the  indemnification  of the  Holders,  if  requested  in  connection  with  any
Registration Statement.

          (b) Each Holder  agrees,  severally and not jointly,  to indemnify and
hold harmless the Company,  the Guarantors,  the Placement  Agents and the other
selling Holders, and each of their respective  directors,  officers who sign the
Registration  Statement and each Person,  if any, who controls the Company,  any
Guarantor,  any Placement  Agent and any other selling Holder within the meaning
of either  Section  15 of the 1933 Act or Section 20 of the 1934 Act to the same
extent as the  foregoing  indemnity  from the Company and the  Guarantors to the
Placement  Agents  and the  Holders,  but only  with  reference  to  information
relating to such Holder  furnished to the Company or any Guarantor in writing by
such Holder  expressly for use in any  Registration  Statement (or any amendment
thereto) or any Prospectus (or any amendment or supplement thereto).

          (c) In case any proceeding (including any governmental  investigation)
shall be instituted  involving  any Person in respect of which  indemnity may be
sought pursuant to either paragraph (a) or paragraph (b) above, such Person (the
"indemnified  party")  shall  promptly  notify  the  Person  against  whom  such
indemnity  may  be  sought  (the  "indemnifying   party")  in  writing  and  the
indemnifying  party, upon request of the indemnified party, shall retain counsel
reasonably  satisfactory to the  indemnified  party to represent the indemnified
party and any others the indemnifying party may designate in such proceeding and
shall pay the fees and disbursements of such counsel related to such proceeding.
In any such proceeding, any indemnified party shall have the right to retain its
own counsel,  but the fees and expenses of such counsel  shall be at the expense
of such indemnified party unless (i) the indemnifying  party and the indemnified
party shall have  mutually  agreed to the  retention of such counsel or (ii) the
named parties to any such proceeding  (including any impleaded  parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel  would be  inappropriate  due to actual or potential
differing  interests between them. It is understood that the indemnifying  party
shall not, in connection with any proceeding or related  proceedings in the same
jurisdiction,  be liable for (a) the fees and expenses of more than one separate
firm (in  addition  to any  local  counsel)  for the  Placement  Agents  and all
Persons,  if any, who control any  Placement  Agent within the meaning of either
Section  15 of the 1933 Act or  Section  20 of the  1934  Act,  (b) the fees and
expenses of more than one separate  firm (in addition to any local  counsel) for
the Company and the Guarantors,  their  respective  directors,  their respective
officers  who sign the  Registration  Statement  and each  Person,  if any,  who
controls the Company or any Guarantor  within the meaning of either such Section
and (c) the fees and expenses of more than one separate firm (in addition to any
local counsel) for all Holders and all Persons,  if any, who control any Holders
within the meaning of either such  Section,  and that all such fees and expenses



                                      E-139

<PAGE>


shall be reimbursed as they are incurred.  In such case  involving the Placement
Agents  and  Persons  who  control  the  Placement  Agents,  such firm  shall be
designated  in  writing  by  Morgan  Stanley  & Co.  Incorporated.  In such case
involving the Holders and such Persons who control  Holders,  such firm shall be
designated  in writing by the Majority  Holders.  In all other cases,  such firm
shall be designated by the Company.  The indemnifying  party shall not be liable
for any settlement of any proceeding  effected  without its written consent but,
if settled with such consent or if there be a final  judgment for the plaintiff,
the  indemnifying  party  agrees to  indemnify  the  indemnified  party from and
against  any  loss or  liability  by  reason  of such  settlement  or  judgment.
Notwithstanding  the foregoing  sentence,  if at any time an  indemnified  party
shall have requested an indemnifying  party to reimburse the  indemnified  party
for fees and  expenses  of  counsel  as  contemplated  by the  second  and third
sentences  of this  paragraph,  the  indemnifying  party agrees that it shall be
liable for any settlement of any proceeding effected without its written consent
if (i) such  settlement  is entered into more than 30 days after receipt by such
indemnifying  party of the aforesaid  request and (ii) such  indemnifying  party
shall not have  reimbursed the  indemnified  party for such fees and expenses of
counsel in accordance with such request prior to the date of such settlement. No
indemnifying  party shall,  without the prior written consent of the indemnified
party, effect any settlement of any pending or threatened  proceeding in respect
of which  such  indemnified  party is or could  have been a party and  indemnity
could  have  been  sought  hereunder  by such  indemnified  party,  unless  such
settlement includes an unconditional  release of such indemnified party from all
liability on claims that are the subject matter of such proceeding.


          (d) If the indemnification  provided for in paragraph (a) or paragraph
(b) of this Section 5 is unavailable to an indemnified  party or insufficient in
respect of any losses,  claims,  damages or liabilities,  then each indemnifying
party under such  paragraph,  in lieu of  indemnifying  such  indemnified  party
thereunder,  shall  contribute to the amount paid or payable by such indemnified
party as a  result  of such  losses,  claims,  damages  or  liabilities  in such
proportion as is appropriate  to reflect the relative fault of the  indemnifying
party or parties on the one hand and of the indemnified  party or parties on the
other hand in connection  with the statements or omissions that resulted in such
losses, claims, damages or liabilities,  as well as any other relevant equitable
considerations.  The  relative  fault of the  Company,  the  Guarantors  and the
Holders shall be  determined  by reference  to, among other things,  whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company
and  the  Guarantors  or by  the  Holders  and  the  parties'  relative  intent,
knowledge,  access to  information  and  opportunity  to correct or prevent such
statement  or  omission.  The  Holders'  respective  obligations  to  contribute
pursuant  to this  Section  5(d) are  several in  proportion  to the  respective
principal  amount of Registrable  Securities of such Holder that were registered
pursuant to a Registration Statement.

          (e) The Company,  each  Guarantor  and each Holder agree that it would
not be just or  equitable  if  contribution  pursuant  to  this  Section  5 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 paragraph (d)
above.  The amount  paid or payable by an  indemnified  party as a result of the
losses, claims, damages and liabilities referred to in paragraph (d) above shall
be deemed to include,  subject to the limitations set forth above,  any legal or
other expenses  reasonably incurred by such indemnified party in connection with
investigating  or  defending  any such  action  or  claim.  Notwithstanding  the
provisions  of this  Section 5, no Holder  shall be  required  to  indemnify  or
contribute  any amount in excess of the amount by which the total price at which
Registrable  Securities  were  sold by such  Holder  exceeds  the  amount of any
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 1933 Act)  shall be  entitled  to  contribution  from any Person who was not
guilty of such fraudulent  misrepresentation.  The remedies provided for in this
Section 5 are not exclusive and shall not limit any rights or remedies which may
otherwise be available to any indemnified party at law or in equity.



                                      E-140

<PAGE>



          The indemnity and contribution  provisions contained in this Section 5
shall  remain  operative  and in full  force and  effect  regardless  of (i) any
termination of this Agreement,  (ii) any  investigation  made by or on behalf of
the Placement Agents,  any Holder or any Person  controlling any Placement Agent
or any  Holder,  or by or on behalf of the  Company or any  Guarantor,  or their
respective  officers or directors,  or any Person controlling the Company or any
Guarantor,  (iii) acceptance of any of the Exchange Securities and (iv) any sale
of Registrable Securities pursuant to a Shelf Registration Statement.

          10. Miscellaneous.

          (a) No  Inconsistent  Agreements.  The Company and the Guarantors have
not  entered  into,  and on or after the date of this  Agreement  will not enter
into, any agreement which is inconsistent with the rights granted to the Holders
of  Registrable  Securities in this  Agreement or otherwise  conflicts  with the
provisions hereof. The rights granted to the Holders hereunder do not in any way
conflict with and are not inconsistent with the rights granted to the holders of
the Company's or any Guarantor's  other issued and outstanding  securities under
any such agreements.

          (b)  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  in  aggregate  principal  amount  of the  outstanding
Registrable  Securities  affected by such amendment,  modification,  supplement,
waiver  or  consent;  provided,   however,  that  no  amendment,   modification,
supplement,  waiver or consent to any departure from the provisions of Section 5
hereof shall be effective as against any Holder of Registrable Securities unless
consented to in writing by such Holder.

          (c)  Notices.  All notices and other  communications  provided  for or
permitted  hereunder  shall  be made in  writing  by  hand-delivery,  registered
first-class  mail,  telex,  telecopier,  or any courier  guaranteeing  overnight
delivery (i) if to a Holder, at the most current address given by such Holder to
the Company by means of a notice given in accordance with the provisions of this
Section 6(c), which address  initially is, with respect to the Placement Agents,
the address set forth in the Placement Agreement;  and (ii) if to the Company or
any Guarantor,  initially at the Company's or the Guarantor's respective address
set forth in the  Placement  Agreement  and  thereafter  at such other  address,
notice of which is given in accordance with the provisions of this Section 6(c).

          All such notices and communications  shall be deemed to have been duly
given:  at the time  delivered by hand, if personally  delivered;  five business
days after  being  deposited  in the mail,  postage  prepaid,  if  mailed;  when
answered back, if telexed; when receipt is acknowledged,  if telecopied;  and on
the  next  business  day if  timely  delivered  to an air  courier  guaranteeing
overnight delivery.

          Copies of all such notices,  demands, or other communications shall be
concurrently  delivered  by the Person  giving the same to the  Trustee,  at the
address specified in the Indenture.

          (d) Successors and Assigns.  This Agreement shall inure to the benefit
of and be binding upon the  successors,  assigns and  transferees of each of the
parties,  including,  without  limitation  and  without  the need for an express
assignment,  subsequent Holders; provided that nothing herein shall be deemed to
permit any assignment,  transfer or other disposition of Registrable  Securities
in violation of the terms of the Placement  Agreement.  If any transferee of any
Holder shall acquire Registrable Securities, in any manner, whether by operation
of law or otherwise, such Registrable Securities shall be held subject to all of
the  terms  of this  Agreement,  and by  taking  and  holding  such  Registrable
Securities such Person shall be  conclusively  deemed to have agreed to be bound


                                      E-141

<PAGE>


by and to perform all of the terms and  provisions  of this  Agreement  and such
Person shall be entitled to receive the benefits  hereof.  The Placement  Agents
(in their capacity as Placement Agents) shall have no liability or obligation to
the Company and the Guarantors with respect to any failure by a Holder to comply
with,  or any breach by any Holder of,  any of the  obligations  of such  Holder
under this Agreement.

          (e) Purchases and Sales of Securities.  The Company and the Guarantors
shall  not,  and shall use their  best  efforts to cause  their  affiliates  (as
defined  in Rule 405  under the 1933 Act) not to,  purchase  and then  resell or
otherwise transfer any Securities.

          (f)  Third  Party  Beneficiary.  The  Holders  shall  be  third  party
beneficiaries  to the  agreements  made  hereunder  between  the Company and the
Guarantors,  on the one hand, and the Placement  Agents,  on the other hand, and
shall have the right to enforce such agreements  directly to the extent it deems
such  enforcement  necessary or advisable to protect its rights or the rights of
Holders hereunder.

          (g)  Counterparts.  This  Agreement  may be  executed in any number of
counterparts and by the parties hereto in separate  counterparts,  each of which
when so  executed  shall be  deemed  to be an  original  and all of which  taken
together shall constitute one and the same agreement.

          (h) Headings.  The headings in this  Agreement are for  convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

          (i) Governing Law. This Agreement shall be governed by the laws of the
State of New York.

          (j) Severability.  In the event that any one or more of the provisions
contained  herein,  or the  application  thereof  in any  circumstance,  is held

             DEFINITIONS AND OTHER PROVISIONS OF GENERAL APPLICATION

     Section 1.1 Definitions.

     "Acquired  Indebtedness" means Indebtedness of a Person (a) existing at the
time such Person  becomes a Restricted  Subsidiary  or (b) assumed in connection
with  acquisitions of Properties  from such Person (other than any  Indebtedness
incurred in connection  with,  or in  contemplation  of, such Person  becoming a
Restricted  Subsidiary  or such  acquisition).  Acquired  Indebtedness  shall be
deemed to be  incurred  on the date the  acquired  Person  becomes a  Restricted
Subsidiary  or the date of the  related  acquisition  of  Properties  from  such
Person.

     "Act," when used with respect to any Holder,  has the meaning  specified in
Section 13.3.

     "Additional   Assets"  means  (i)  any  Property  (other  than  cash,  Cash
Equivalents  or  securities)  used in the Oil and Gas  Business or any  business
ancillary  thereto,  (ii) Investments in any other Person engaged in the Oil and
Gas Business or any business  ancillary thereto  (including the acquisition from
third  parties of Capital  Stock of such Person) as a result of which such other
Person becomes a Restricted Subsidiary, (iii) the acquisition from third parties
of Capital  Stock of a Restricted  Subsidiary  or (iv)  Investments  pursuant to
clause (v) of the definition of "Permitted Investments."

     "Adjusted Consolidated Net Tangible Assets" means (without duplication), as

     (i) the sum of (A)  discounted  future net revenues from proved oil and gas
reserves of the Company and its Restricted Subsidiaries calculated in accordance
with Commission guidelines before any state, federal or foreign income taxes, as
estimated  by the Company  and  confirmed  by a  nationally  recognized  firm of
independent  petroleum  engineers in a reserve report  prepared as of the end of
the Company's most recently  completed  fiscal year for which audited  financial
statements are available, as increased by, as of the date of determination,  the
estimated  discounted  future net revenues from (1) estimated proved oil and gas
reserves acquired since such year-end, which reserves were not reflected in such
year-end reserve report, and (2) estimated oil and gas reserves  attributable to
upward revisions of estimates of proved oil and gas reserves since such year-end
due to  exploration,  development  or  exploitation  activities,  in  each  case
calculated  in  accordance  with  Commission  guidelines  (utilizing  the prices
utilized in such year-end reserve  report),  and decreased by, as of the date of
determination,  the estimated  discounted future net revenues from (3) estimated
proved oil and gas reserves  produced or disposed of since such year-end and (4)
estimated oil and gas reserves  attributable to downward  revisions of estimates
of proved oil and gas reserves  since such year-end due to changes in geological
conditions or other factors which would,  in accordance  with standard  industry
practice,  cause such  revisions,  in each case  calculated in  accordance  with
Commission  guidelines  (utilizing the prices utilized in such year-end  reserve
report);  provided that, in the case of each of the determinations made pursuant
to clauses (1) through (4), such  increases and decreases  shall be as estimated


                                      E-145

by the Company's  petroleum  engineers,  unless there is a Material  Change as a

discounted future net revenues utilized for purposes of this clause (i)(A) shall
be confirmed in writing by a nationally recognized firm of independent petroleum
engineers,  (B) the  capitalized  costs  that  are  attributable  to oil and gas
properties of the Company and its Restricted Subsidiaries to which no proved oil
and gas reserves are  attributable,  based on the Company's books and records as

financial statements,  (C) the Net Working Capital on a date no earlier than the

third parties to fully satisfy the obligations of the Company and its Restricted
Subsidiaries  with respect to Volumetric  Production  Payments  (determined,  if
applicable,  using the  schedules  specified  with respect  thereto) and (D) the
discounted  future  net  revenues,  calculated  in  accordance  with  Commission
guidelines,  attributable to reserves subject to  Dollar-Denominated  Production

as required to be paid under such lease  subsequent to the first date upon which
it may be so terminated.

     "Average Life" means, with respect to any  Indebtedness,  as at any date of

or any  Restricted  Subsidiary  (other than any  Permitted  Lien or any Lien the
creation or imposition of which shall have been in compliance  with Section 9.14
hereof);  provided,  however,  that with respect to clause (a), the Company or a
Restricted  Subsidiary  may  be  liable  for  Indebtedness  of  an  Unrestricted
Subsidiary  if (1)  such  liability  constituted  a  Permitted  Investment  or a
Restricted  Payment permitted by Section 9.9 hereof, in each case at the time of
incurrence,  or (2) the liability would be a Permitted Investment at the time of
designation  of  such  Subsidiary  as  an  Unrestricted  Subsidiary.   Any  such
designation  by the Board of Directors of the Company  shall be evidenced to the
Trustee by filing a Board  Resolution  with the  Trustee  giving  effect to such
designation.   The  Board  of  Directors  of  the  Company  may   designate  any
Unrestricted  Subsidiary as a Restricted Subsidiary if, immediately after giving
effect to such  designation,  on a pro forma  basis (i) no  Default  or Event of
Default  shall have  occurred and be  continuing,  (ii) the Company  could incur
$1.00 of additional  Indebtedness  (not  including  the  incurrence of Permitted
Indebtedness) under Section 9.11(a) hereof and (iii) if any of the Properties of
the Company or any of its Restricted  Subsidiaries  would upon such  designation
become  subject to any Lien  (other  than a  Permitted  Lien),  the  creation or
imposition of such Lien shall have been in compliance with Section 9.14 hereof.

     "Vice  President,"  when used with  respect to the Company or the  Trustee,

words added before or after the title "vice president."

the happening of any contingency).

(ii) such Restricted Subsidiary does substantially all of its business in one or
more  foreign   jurisdictions  and  is  required  by  the  applicable  laws  and

regulations  of any  such  foreign  jurisdiction  to be  partially  owned by the
government of such foreign  jurisdiction or individual or corporate  citizens of

indirectly,  owns the  remaining  Capital  Stock or  ownership  interest in such
Restricted Subsidiary and, by contract or otherwise, controls the management and
business of such  Restricted  Subsidiary  and derives the  economic  benefits of
ownership of such Restricted  Subsidiary to substantially  the same extent as if

     The aggregate  principal  amount of Securities  Outstanding at any one time
may not exceed  $225,000,000  except as  provided  in Section  2.7  hereof.  All
Securities  shall be  identical  in all  respects  other  than  issue  price and

however,  that any Securities  issued with original  issue discount  ("OID") for
Federal  income tax  purposes  shall not be issued as part of the same series as
any Securities that are issued with a different  amount of OID or are not issued
with OID.

     Subject to Section  2.3,  the Trustee  shall  authenticate  Securities  for
original  issue  on  the  Issue  Date  in  the  aggregate  principal  amount  of
$150,000,000 (the "Original Securities").  With respect to any Securities issued

pursuant to Section  2.7,  2.8,  2.9,  9.15,  9.16 or 10.6 or Appendix A), there
shall be  established  in or pursuant to a resolution  of the Board of Directors

an Officer's Certificate,  or established in one or more indentures supplemental
hereto, prior to the issuance of such Securities:


                                      E-165

<PAGE>



     (1) whether  such  Securities  shall be issued as part of a new or existing
series of Securities and the title of such Securities  (which shall  distinguish
the Securities of the series from Securities of any other series);

     (2)  the  aggregate  principal  amount  of  such  Securities  which  may be
authenticated and delivered under this Indenture, which shall be in an aggregate
principal amount not to exceed $75,000,000 (except for Securities  authenticated
and delivered upon  registration  of transfer of, or in exchange for, or in lieu
of, other Securities of the same series pursuant to Section 2.7, 2.8, 2.9, 9.15,
9.16 or 10.6 or Appendix A and except for Securities which,  pursuant to Section
2.3, are deemed never to have been authenticated and delivered hereunder);

     (3) the issue price and issuance  date of such  Securities,  including  the
date from which interest on such Securities shall accrue;

     (4) if applicable,  that such  Securities  shall be issuable in whole or in
part  in the  form of one or more  Global  Securities  and,  in such  case,  the
respective  depositories for such Global  Securities,  the form of any legend or
legends  which shall be borne by any such  Global  Security in addition to or in
lieu of that set  forth in  Exhibit 1 to  Appendix  A and any  circumstances  in
addition  to or in lieu of those set forth in Section 2.3 of Appendix A in which
any such Global  Security may be  exchanged  in whole or in part for  Securities
registered,  and any transfer of such Global Security in whole or in part may be
registered,  in the name or names of Persons other than the  depository for such
Global Security or a nominee thereof; and

     (5) if applicable,  that such Securities shall not be issued in the form of
Initial  Securities  subject to  Appendix  A, but shall be issued in the form of
Exchange Securities as set forth in Exhibit A.

     If any of the terms of any series are  established by action taken pursuant
to a resolution of the Board of Directors,  a copy of an  appropriate  record of
such action shall be certified by the  Secretary or any  Assistant  Secretary of
the Company  and  delivered  to the  Trustee at or prior to the  delivery of the
Officers' Certificate or the trust indenture supplementary thereto setting forth
the terms of the series.

     Notwithstanding  anything to the  contrary in this  Section or otherwise in
this  Indenture,  any  additional  issuance of Securities  after the Issue Date,
whether such Securities are of the same or a different  series than the Original
Securities, shall be in a principal amount greater than or equal to $25,000,000.

         Section 2.2       Form and Dating.

         Provisions  relating to the Initial  Securities  of each series and the
Exchange Securities are set forth in Appendix A, which is hereby incorporated in
and  expressly  made a part of this  Indenture.  The Initial  Securities of each
series and the Trustee's certificate of authentication shall be substantially in
the  form of  Exhibit  1 to  Appendix  A which  is  hereby  incorporated  in and
expressly  made a part  of  this  Indenture.  The  Exchange  Securities  and the
Trustee's  certificate of  authentication  shall be substantially in the form of
Exhibit A, which is hereby  incorporated  in and  expressly  made a part of this
Indenture.  The  Securities  of each  series  may  have  notations,  legends  or
endorsements  required by law,  stock  exchange  rule,  agreements  to which the
Company is subject, if any, or usage, provided that any such notation, legend or
endorsement  is in a form  reasonably  acceptable to the Company.  Each Security
shall be dated the date of its  authentication.  The terms of the  Securities of
each  series set forth in Exhibit 1 to  Appendix A and Exhibit A are part of the
terms of this Indenture.


                                      E-166

     Section 2.3 Execution and Authentication.

     Two Officers of the Company  shall sign the  Securities  for the Company by
manual or facsimile  signature.  The Company's  seal may be impressed,  affixed,
imprinted or reproduced on the Securities and may be in facsimile form.

     If an Officer whose  signature is on a Security no longer holds that office
at the time the Trustee authenticates the Security,  the Security shall be valid
nevertheless.

     At any time and from time to time after the  execution and delivery of this
Indenture,  the  Company may deliver  Securities  of any series  executed by the
Company to the Trustee for authentication,  together with a written order of the
Company  signed  by two  Officers  of the  Company  for the  authentication  and
delivery of such  Securities,  and the Trustee in  accordance  with such written
order of the Company shall authenticate and deliver such Securities.

     A Security shall not be valid until an authorized  signatory of the Trustee
manually signs the certificate of authentication on the Security.  The signature
shall be conclusive evidence that the Security has been authenticated under this
Indenture.

     The Trustee may appoint an  authenticating  agent reasonably  acceptable to
the Company to authenticate the Securities.  Unless limited by the terms of such
appointment,  an authenticating  agent may authenticate  Securities whenever the
Trustee may do so. Each  reference in this  Indenture to  authentication  by the
Trustee includes  authentication by such agent. An authenticating  agent has the
same rights as any  Registrar,  Paying Agent or agent for service of notices and
demands.

     Section 2.4 Registrar and Paying Agent.

     The Company  shall  maintain an office or agency  where  Securities  may be
presented for registration of transfer or for exchange (the  "Registrar") and an
office or agency  where  Securities  may be  presented  for payment (the "Paying
Agent").  The Registrar  shall keep a register (the "Security  Register") of the
Securities and of their transfer and exchange.  The Company may have one or more
co-registrars and one or more additional paying agents.  The term "Paying Agent"
includes any additional paying agent.

     The  Company  shall enter into an  appropriate  agency  agreement  with any
Registrar,  Paying Agent or co-registrar  not a party to this  Indenture,  which
shall  incorporate  the terms of the TIA.  The  agreement  shall  implement  the
provisions of this Indenture that relate to such agent. The Company shall notify
the Trustee of the name and address of any such agent.  If the Company  fails to
maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be
entitled to  appropriate  compensation  therefor  pursuant to Section  5.6.  The
Company may act as Paying Agent, Registrar, co-registrar or transfer agent.

     The Company initially appoints the Trustee as Registrar and Paying Agent in
connection with the Securities.

     Section 2.5 Paying Agent To Hold Money in Trust.

     Not later than 10:00 a.m.,  Eastern  standard time, on each due date of the
principal  and  interest on any  Security,  the Company  shall  deposit with the
Paying  Agent a sum  sufficient  to pay  such  principal  and  interest  when so
becoming  due.  The Company  shall  require  each Paying  Agent  (other than the
Trustee) to agree in writing  that the Paying  Agent shall hold in trust for the
benefit of Securityholders or the Trustee all money held by the Paying Agent for
the payment of principal of or interest on the  Securities  and shall notify the
Trustee of any default by the Company in making any such payment. If the Company
acts as Paying  Agent,  it shall  segregate the money held by it as Paying Agent
and hold it as a separate  trust  fund.  The  Company at any time may  require a
Paying  Agent to pay all money held by it to the  Trustee and to account for any


                                      E-167

<PAGE>



funds  disbursed by the Paying Agent.  Upon  complying  with this  Section,  the
Paying  Agent shall have no further  liability  for the money  delivered  to the
Trustee.

     Section 2.6 Securityholder Lists.

     The  Trustee  shall  preserve  in  as  current  a  form  as  is  reasonably
practicable  the most recent list  available to it of the names and addresses of
Securityholders.  If the Trustee is not the Registrar, the Company shall furnish
to the  Trustee,  in writing at least five  Business  Days before each  interest
payment  date and at such other times as the  Trustee may request in writing,  a
list in such form and as of such date as the Trustee may  reasonably  require of
the names and addresses of Securityholders.

     Section 2.7 Replacement Securities.

     If a mutilated Security is surrendered to the Registrar or if the Holder of
a Security  claims that such  Security has been lost,  destroyed  or  wrongfully
taken, the Company shall issue and the Trustee shall  authenticate a replacement
Security if the requirements of Section 8-405 of the Uniform Commercial Code are
met and the Holder satisfies any other  reasonable  requirements of the Trustee.
If  required  by the  Trustee  or the  Company,  such  Holder  shall  furnish an
indemnity  bond  sufficient  in the  judgment  of the Company and the Trustee to
protect the Company,  the  Trustee,  the Paying  Agent,  the  Registrar  and any
co-registrar  from any  loss  which  any of them may  suffer  if a  Security  is
replaced.  The Company and the Trustee may charge the Holder for their  expenses
in replacing a Security.

     Every replacement Security is an additional obligation of the Company.

     Section 2.8 Outstanding Securities.

     Securities outstanding at any time are all Securities  authenticated by the
Trustee except for those canceled by it, those delivered to it for  cancellation
and those  described in this  Section as not  outstanding.  A Security  does not
cease to be outstanding because the Company or an Affiliate of the Company holds
the Security.

     If a  Security  is  replaced  pursuant  to  Section  2.7,  it  ceases to be
outstanding  unless the Trustee and the Company  receive proof  satisfactory  to
them that the replaced Security is held by a bona fide purchaser.

     If the Paying Agent  segregates and holds in trust, in accordance with this
Indenture,  on a redemption  date or maturity  date money  sufficient to pay all
principal and interest  payable on that date with respect to the  Securities (or
portions thereof) to be redeemed or maturing, as the case may be, and the Paying
Agent is not prohibited  from paying such money to the  Securityholders  on that
date pursuant to the terms of this  Indenture,  then on and after that date such
Securities (or portions  thereof)  cease to be outstanding  and interest on them
ceases to accrue.

     Section 2.9 Temporary Securities.

     Until definitive Securities are ready for delivery, the Company may prepare
and the Trustee shall authenticate  temporary  Securities.  Temporary Securities
shall  be  substantially  in the  form of  definitive  Securities  but may  have
variations  that the Company  considers  appropriate  for temporary  Securities.
Without  unreasonable  delay,  the Company  shall  prepare and the Trustee shall
authenticate  definitive  Securities  and deliver them in exchange for temporary
Securities.



                                      E-168

<PAGE>


     Section 2.10 Cancellation.

     The  Company  at  any  time  may  deliver  Securities  to the  Trustee  for
cancellation.  The  Registrar  and the Paying Agent shall forward to the Trustee
any Securities  surrendered to them for  registration  of transfer,  exchange or
payment.  The Trustee and no one else shall  cancel and destroy  (subject to the
record  retention  requirements of the Exchange Act) all Securities  surrendered
for registration of transfer,  exchange, payment or cancellation and shall, upon
written request,  deliver a certificate of such destruction to the Company.  The
Company may not issue new Securities to replace Securities it has redeemed, paid
or delivered to the Trustee for cancellation.

     Section 2.11 Defaulted Interest.

     If the Company  defaults in a payment of  interest  on the  Securities,  it
shall pay the  defaulted  interest  in any  lawful  manner  plus,  to the extent
lawful,  interest  payable on the  defaulted  interest,  to the  persons who are
Securityholders  on a subsequent  special  record date, in each case at the rate
provided in the Securities  and in Section 9.1 hereof.  The Company shall fix or
cause  to be  fixed  any  such  special  record  date  and  payment  date to the
reasonable  satisfaction  of  the  Trustee  and  shall  promptly  mail  to  each
Securityholder  a notice that states the special  record date,  the payment date
and the amount of defaulted interest to be paid.

     Section 2.12 CUSIP Numbers.

     The Company in issuing  the  Securities  may use  "CUSIP"  numbers (if then
generally in use) and, if so, the Trustee  shall use "CUSIP"  numbers in notices
of redemption  as a convenience  to Holders;  provided,  however,  that any such
notice may state that no  representation  is made as to the  correctness of such
numbers  either as printed on the  Securities or as contained in any notice of a
redemption  and that  reliance  may be placed  only on the other  identification
numbers printed on the Securities, and any such redemption shall not be affected
by any defect in or omission of such numbers.

                                  ARTICLE III.

                           SATISFACTION AND DISCHARGE

     Section 3.1 Satisfaction and Discharge of Indenture.

     This  Indenture  shall upon Company  Request cease to be of further  effect

Securities,  as expressly  provided for in this Indenture) as to all Outstanding
Securities,  and the Trustee, at the expense of the Company, shall, upon payment
of all  amounts  due the  Trustee  under  Section  5.6  hereof,  execute  proper
instruments acknowledging satisfaction and discharge of this Indenture when

     (a) either

     (i)  Securities  which have been replaced as provided in Section 2.7 hereof
     and (ii)  Securities for whose payment money or United States  governmental
     obligations  of the type  described in clause (i) of the definition of Cash
     Equivalents  have  theretofore  been deposited in trust with the Trustee or
     any  Paying  Agent or  segregated  and held in  trust  by the  Company  and
     thereafter repaid to the Company or discharged from such trust, as provided
     in Section 9.3 hereof) have been delivered to the Trustee for cancellation,
     or

          (2) all such Securities not  theretofore  delivered to the Trustee for
     cancellation

               (i) have become due and payable, or


                                      E-169

<PAGE>



               (ii) will become due and payable at their Stated  Maturity within
          one year, or

               (iii) are to be  called  for  redemption  within  one year  under
          arrangements  satisfactory  to the Trustee for the giving of notice of
          redemption  by the  Trustee in the name,  and at the  expense,  of the
          Company,

     and the Company,  in the case of clause (2)(i),  (2)(ii) or (2)(iii) above,
     has irrevocably  deposited or caused to be deposited with the Trustee funds
     in an amount  sufficient to pay and discharge  the entire  indebtedness  on
     such Securities not theretofore  delivered to the Trustee for cancellation,
     for  principal  (and  premium,  if any)  and  interest  to the date of such
     deposit (in the case of Securities which have become due and payable) or to
     the Stated  Maturity or Redemption  Date, as the case may be, together with
     instructions  from the Company  irrevocably  directing the Trustee to apply
     such funds to the payment  thereof at maturity or  redemption,  as the case
     may be;

          (b) the  Company has paid or caused to be paid all other sums then due
     and payable hereunder by the Company; and

          (c) the Company has delivered to the Trustee an Officers'  Certificate
     and an Opinion of Counsel, which, taken together, state that all conditions
     precedent  herein  relating  to the  satisfaction  and  discharge  of  this
     Indenture have been complied with.

     Notwithstanding  the  satisfaction  and  discharge of this  Indenture,  the
obligations of the Company to the Trustee under Section 5.6 hereof and, if money
shall  have been  deposited  with the  Trustee  pursuant  to this  Section,  the
obligations  of the Trustee under  Section 3.2 hereof and the last  paragraph of
Section 9.3 hereof shall survive.

     Section 3.2 Application of Trust Money.

     Subject to the provisions of the last paragraph of Section 9.3 hereof,  all
money deposited with the Trustee pursuant to Section 3.1 hereof shall be held in
trust and applied by it, in accordance with the provisions of the Securities and
this  Indenture,  to the  payment,  either  directly or through any Paying Agent
(including  the  Company  acting as its own  Paying  Agent) as the  Trustee  may
determine,  to the Persons entitled thereto,  of the principal (and premium,  if
any) and  interest  for whose  payment  such money has been  deposited  with the
Trustee.

                                   ARTICLE IV.

     "Event of Default,"  wherever  used herein,  means any one of the following
events  (whatever  the reason for such Event of Default  and whether it shall be
voluntary or  involuntary  or be effected by operation of law or pursuant to any
judgment,  decree or order of any court or any order,  rule or regulation of any
administrative or governmental body):

     (a) default in the payment of the  principal of or premium,  if any, on any

due at Stated Maturity, upon redemption, upon repurchase pursuant to a Change of
Control Offer or a Prepayment Offer, upon acceleration or otherwise; or

     (b) default in the payment of any installment of interest on any of the
Securities, when it becomes due and payable, and the continuance of such default

     Section 4.2 Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default (other than an Event of Default specified in Section
4.1(h) or (i) hereof)  occurs and is  continuing,  the Trustee or the Holders of
not  less  than  25%  in  aggregate  principal  amount  of the  Securities  then
Outstanding, by written notice to the Company (and to the Trustee if such notice
is given by the  Holders),  may, and the Trustee upon the request of the Holders
of not less than 25% in aggregate principal amount of the Outstanding Securities
shall, by a notice in writing to the Company,  declare all unpaid  principal of,
premium, if any, and accrued and unpaid interest on all the Securities to be due
and payable  immediately,  upon which declaration all amounts payable in respect
of the Securities  shall be immediately due and payable.  If an Event of Default
specified in Section 4.1(h) or (i) hereof occurs and is continuing,  the amounts
described  above shall  become and be  immediately  due and payable  without any
declaration, notice or other act on the part of the Trustee or any Holder.

     Promptly after the occurrence of a declaration of acceleration, the Company
shall notify each holder of Senior Indebtedness thereof, but failure to give any
such notice shall not affect such declaration or its consequences.

     At any time after a declaration of acceleration  has been made and before a
judgment or decree for payment of the money due has been obtained by the Trustee
as hereinafter in this Article provided,  the Holders of a majority in aggregate
principal  amount  of the  Securities  Outstanding,  by  written  notice  to the
Company,  the Subsidiary  Guarantors and the Trustee, may rescind and annul such
declaration and its consequences if

     (a) the Company or any Subsidiary  Guarantor has paid or deposited with the
Trustee a sum sufficient to pay,

          (1) all overdue interest on all Outstanding Securities,

          (2) all unpaid principal of (and premium,  if any, on) any Outstanding
     Securities  which have become due  otherwise  than by such  declaration  of
     acceleration, including any Securities required to have been purchased on a
     Change of Control Date or a Purchase  Date  pursuant to a Change of Control
     Offer or a Prepayment  Offer,  as  applicable,  and interest on such unpaid
     principal at the rate borne by the Securities,

          (3) to the extent that payment of such interest is lawful, interest on
     overdue interest and overdue  principal at the rate borne by the Securities
     (without  duplication  of any amount paid or deposited  pursuant to clauses
     (1) and (2) above), and

          (4) all  sums  paid  or  advanced  by the  Trustee  hereunder  and the
     reasonable  compensation,  expenses,  disbursements  and  advances  of  the
     Trustee, its agents and counsel;

     (b) the  rescission  would not  conflict  with any  judgment or decree of a
court of competent jurisdiction as  certified to the Trustee by the Company; and

                                      E-172

<PAGE>



     (c) all  Events of  Default,  other  than the  non-payment  of  amounts  of
principal  of (or  premium,  if any,  on) or interest on  Securities  which have
become due solely by such declaration of acceleration, have been cured or waived
as provided in Section 4.13 hereof.

     No such rescission shall affect any subsequent  default or impair any right
consequent thereon.

     Notwithstanding the foregoing,  if an Event of Default specified in Section
4.1(e) hereof shall have occurred and be  continuing,  such Event of Default and
any  consequential   acceleration  shall  be  automatically   rescinded  if  the
Indebtedness that is the subject of such Event of Default has been repaid, or if
the  default  relating  to such  Indebtedness  is  waived  or cured  and if such
Indebtedness has been accelerated, then the holders thereof have rescinded their
declaration of acceleration in respect of such Indebtedness  (provided,  in each
case,  that such  repayment,  waiver,  cure or rescission  is effected  within a
period of 10 days from the  continuation  of such default  beyond the applicable
grace period or the occurrence of such acceleration), and written notice of such
repayment, or cure or waiver and rescission, as the case may be, shall have been
given to the  Trustee by the Company  and  countersigned  by the holders of such
Indebtedness or a trustee, fiduciary or agent for such holders or other evidence
satisfactory to the Trustee of such events is provided to the Trustee, within 30
days after any such  acceleration in respect of the  Securities,  and so long as
such  rescission of any such  acceleration  of the Securities  does not conflict
with any judgment or decree as certified to the Trustee by the Company.

     Section  4.3  Collection  of  Indebtedness  and  Suits for  Enforcement  by
Trustee.

     The Company covenants that if

     (a)  default is made in the payment of any  installment  of interest on any
Security when such interest  becomes due and payable and such default  continues
for a period of 30 days, or

     (b) default is made in the payment of the principal of (or premium, if any,
on) any  Security  at the  Maturity  thereof  or with  respect  to any  Security
required to have been purchased by the Company on the Change of Control Purchase
Date or the Purchase  Date  pursuant to a Change of Control  Offer or Prepayment
Offer, as applicable,  then the Company will, upon demand of the Trustee, pay to
the Trustee for the benefit of the Holders of such Securities,  the whole amount
then due and payable on such Securities for principal (and premium,  if any) and
interest,  and interest on any overdue  principal (and premium,  if any) and, to
the extent that payment of such interest shall be legally enforceable,  upon any
overdue  installment of interest,  at the rate borne by the Securities,  and, in
addition thereto,  such further amount as shall be sufficient to cover the costs
and expenses of  collection,  including the reasonable  compensation,  expenses,
disbursements and advances of the Trustee, its agents and counsel.

     If the Company fails to pay such amounts  forthwith  upon such demand,  the
Trustee,  in its own name as  trustee  of an  express  trust,  may  institute  a
judicial  proceeding  for the  collection  of the  sums so due and  unpaid,  may
prosecute  such  proceeding to judgment or final decree and may enforce the same
against the Company or any other  obligor  upon the  Securities  and collect the
money adjudged or decreed to be payable in the manner provided by law out of the
Property  of the  Company or any other  obligor  upon the  Securities,  wherever
situated.

         If an Event of Default occurs and is continuing, the Trustee may in its
discretion  proceed  to  protect  and  enforce  its rights and the rights of the
Holders by such appropriate  judicial proceedings as the Trustee shall deem most
effectual  to protect  and  enforce any such  rights,  whether for the  specific
enforcement  of any  covenant or  agreement  in this  Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

judicial  proceeding  relative to the Company,  any Subsidiary  Guarantor or any
other  obligor  upon the  Securities,  their  creditors  or the  Property of the
Company,  any  Subsidiary  Guarantor  or of  such  other  obligor,  the  Trustee
(irrespective  of whether the principal of the Securities  shall then be due and
payable as therein  expressed or by declaration or otherwise and irrespective of
whether the Trustee  shall have made any demand on the Company,  the  Subsidiary
Guarantors or such other obligor for the payment of overdue principal,  premium,
if any, or interest)  shall be entitled and empowered,  by  intervention in such
proceeding or otherwise,

     (a) to file and  prove a claim  for the  whole  amount  of  principal  (and
premium,  if any) and interest owing and unpaid in respect of the Securities and
to file such other  papers or  documents  and take any other  actions  including
participation  as a full  member of any  creditor or other  committee  as may be
necessary or advisable in order to have the claims of the Trustee (including any
claim for the reasonable compensation,  expenses,  disbursements and advances of
the Trustee, its agents and counsel) and of the Holders allowed in such judicial
proceeding, and

     (b) to  collect  and  receive  any  money  or  other  Property  payable  or
deliverable on any such claims and to distribute the same;

and any custodian,  receiver,  assignee,  trustee,  liquidator,  sequestrator or
similar  official in any such judicial  proceeding is hereby  authorized by each
Holder to make such  payments to the Trustee  and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay the
Trustee  any  amount  due  to it  for  the  reasonable  compensation,  expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 5.6 hereof.

     Nothing  herein  contained  shall be deemed to  authorize  the  Trustee  to
authorize  or  consent to or accept or adopt on behalf of any Holder any plan of
reorganization,  arrangement, adjustment or composition affecting the Securities
or  the  Subsidiary  Guarantees  or the  rights  of any  Holder  thereof,  or to
authorize  the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

the Subsidiary  Guarantees may be prosecuted and enforced by the Trustee without

proceeding relating thereto,  and any such proceeding  instituted by the Trustee
shall be brought in its own name and as  trustee  of an express  trust,  and any
recovery of judgment  shall,  after  provision for the payment of the reasonable
compensation,  expenses,  disbursements and advances of the Trustee,  its agents
and  counsel,  be for the ratable  benefit of the Holders of the  Securities  in
respect of which such judgment has been recovered.


     Section 4.6 Application of Money Collected.

     Any money  collected  by the  Trustee  pursuant  to this  Article  shall be
applied in the following  order,  at the date or dates fixed by the Trustee and,
in the case of the  distribution  of such  money on  account  of  principal  (or
premium,  if any) or  interest,  upon  presentation  of the  Securities  and the

Outstanding  Securities  shall  have made  written  request  to the  Trustee  to
institute  proceedings  in  respect  of such Event of Default in its own name as
Trustee hereunder;

     (c) such  Holder or Holders  have  offered to the Trustee  such  reasonable
indemnity as it may require  against the costs,  expenses and  liabilities to be
incurred in compliance with such request;

     (d) the Trustee for 60 days after its receipt of such  notice,  request and
offer of indemnity has failed to institute any such proceeding; and

     (e) no direction  inconsistent  with such written request has been given to
the Trustee  during  such 60-day  period by the Holders of a majority or more in

right in any manner  whatever by virtue of, or by availing of, any  provision of

right or remedy under this Indenture and such  proceeding has been  discontinued
or abandoned for any reason, or has been determined  adversely to the Trustee or
to such Holder,  then and in every such case,  subject to any  determination  in
such proceeding,  the Company,  the Subsidiary  Guarantors,  the Trustee and the
Holders shall be restored  severally and  respectively to their former positions

in addition to every other right and remedy given  hereunder or now or hereafter

     No delay or  omission  of the  Trustee or of any Holder of any  Security to
exercise any right or remedy accruing upon any Event of Default shall impair any

the Trustee or to the Holders may be exercised  from time to time,  and as often
as may be deemed  expedient,  by the Trustee or by the Holders,  as the case may
be.

     Section 4.12 Control by Holders.

     The Holders of not less than a majority in  aggregate  principal  amount of
the Outstanding  Securities shall have the right to direct the time,  method and
place of conducting any proceeding for any remedy  available to the Trustee,  or
exercising any trust or power conferred on the Trustee, provided that

     (a) such  direction  shall not be in conflict  with any rule of law or with
this Indenture,

     (b) the  Trustee  may take any other  action  deemed  proper by the Trustee
which is not inconsistent with such direction, and

     (c) the Trustee need not take any action which might involve it in personal
liability  or expense  for which the  Trustee  has not  received a  satisfactory

     Section 4.13 Waiver of Past Defaults.

     The Holders of not less than a majority in  aggregate  principal  amount of

     (b) in respect of a covenant or provision  hereof which under  Article VIII
hereof  cannot be modified or amended  without the consent of the Holder of each
Outstanding Security affected thereby.

     Upon any such waiver, such Default or Event of Default shall cease to exist
for every purpose under this  Indenture,  but no such waiver shall extend to any
subsequent  or other  fault or Event of Default  or impair any right  consequent
thereon.

     Section 4.14 Waiver of Stay, Extension or Usury Laws.

     Each of the Company and the Subsidiary  Guarantors covenants (to the extent
that each may lawfully do so) that it will not at any time insist upon, plead or
in any manner  whatsoever  claim or take the benefit or advantage  of, any stay,
extension,  or  usury  law or other  law  wherever  enacted,  now or at any time
hereafter  in  force,  which  would  prohibit  or  forgive  the  Company  or any
Subsidiary  Guarantor  from  paying  all or any  portion  of  the  principal  of
(premium,  if any, on) or interest on the Securities as contemplated  herein, or
which may affect the covenants or the performance of this Indenture; and (to the
extent  that it may  lawfully  do so)  each of the  Company  and the  Subsidiary
Guarantors hereby expressly waives all benefit or advantage of any such law, and
covenant  that they will not hinder,  delay or impede the execution of any power
herein granted to the Trustee, but will suffer and permit the execution of every
such power as though no such law had been enacted.

                                   THE TRUSTEE

     Section 5.1 Duties of Trustee.

     (a) If an Event of Default  has  occurred  and is  continuing,  the Trustee
shall  exercise the rights and powers vested in it by this Indenture and use the
same  degree  of care and skill in their  exercise  as a  prudent  person  would
exercise or use under the circumstances in the conduct of his own affairs.

     (b) Except during the continuance of an Event of Default:

          (i) the Trustee undertakes to perform such duties and only such duties

     therein,  upon  certificates  or  opinions  furnished  to the  Trustee  and
     conforming to the requirements of this Indenture;  provided, however, that,
     in the case of any such  certificates  or opinions  which by any  provision
     hereof are  specifically  required  to be  furnished  to the  Trustee,  the
     Trustee shall examine the certificates and opinions to determine whether or
     not they conform to the requirements of this Indenture, but the Trustee has
     no obligation to determine the accuracy or  completeness  (other than as to
     conformity with the  requirements of this Indenture) of the statements made
     therein.

     (c) The Trustee may not be relieved  from  liability  for its own negligent
action,  its own negligent failure to act or its own wilful  misconduct,  except
that:

          (i) this paragraph shall not limit the effect of Section 5.1(b);

     good faith by a Responsible  Officer,  unless it is proved that the Trustee

     takes  or  omits  to take in good  faith  in  accordance  with a  direction

facsimile  form),  or  document  believed  by it to be genuine  and to have been
signed or presented by the proper party or parties;

an Officers' Certificate;

     (d) the Trustee may consult  with counsel and the advice of such counsel or

     (e) the Trustee  shall be under no obligation to exercise any of the rights
or powers  vested in it by this  Indenture at the request or direction of any of

liabilities  which might be incurred by it in  compliance  with such  request or
direction;

additional  indebtedness  hereunder  and  shall  survive  the  satisfaction  and
discharge of this  Indenture or any other  termination  under any  Insolvency or

funds held in trust for payment of  principal  of (and  premium,  if any, on) or
interest on particular Securities.  Such lien shall survive the satisfaction and

of an Event of Default  specified in paragraph (h) or (i) of Section 4.1 of this

     There shall at all times be a Trustee  hereunder which shall be eligible to
act as Trustee under TIA Section 310(a)(1) and shall have a combined capital and

condition at least annually,  pursuant to law or to the requirements of federal,
state,  territorial or District of Columbia  supervising or examining authority,
then for the purposes of this  Section 5.7, the combined  capital and surplus of
such  corporation  shall be deemed to be its combined capital and surplus as set
forth in its most recent  report of condition so  published.  If at any time the
Trustee  shall cease to be eligible in  accordance  with the  provisions of this
Section,  it  shall  resign  immediately  in the  manner  and  with  the  effect
hereinafter specified in this Article.

     Section 5.8 Conflicting Interests.

securities or certificates of interest or  participation  in other securities of
the Company are outstanding if the  requirements for such exclusion set forth in
TIA Section 310(b)(1) are met.

     Section 5.9 Resignation and Removal; Appointment of Successor.

successor  Trustee  pursuant to this Article  shall become  effective  until the
acceptance  of  appointment  by the  successor  Trustee in  accordance  with the
applicable requirements of Section 5.10 hereof.

     (b) The Trustee may resign at any time by giving  written notice thereof to
the Company.  If the instrument of acceptance by a successor Trustee required by

after the  giving of such  notice of  resignation,  the  resigning  Trustee  may
petition any court of competent  jurisdiction for the appointment of a successor
Trustee.

less  than  a  majority  in  aggregate   principal  amount  of  the  Outstanding
Securities, delivered to the Trustee and to the Company.

     (d) If at any time:

          (1) the  Trustee  shall  fail to  comply  with the  provisions  of TIA
     Section  310(b)  after  written  request  therefor by the Company or by any
     Holder  who has been a bona  fide  Holder  of a  Security  for at least six
     months, or

<PAGE>



          (2) the Trustee  shall cease to be eligible  under  Section 5.7 hereof
     and shall fail to resign after written  request  therefor by the Company or
     by any  Holder who has been a bona fide  Holder of a Security  for at least
     six months, or

          (3) the Trustee shall become  incapable of acting or shall be adjudged
     a bankrupt or  insolvent  or a receiver  of the Trustee or of its  property
     shall be  appointed or any public  officer  shall take charge or control of
     the   Trustee  or  of  its   property   or  affairs   for  the  purpose  of
     rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company,  by a Board Resolution,  may remove the
Trustee,  or (ii) subject to TIA Section 315(e),  any Holder who has been a bona
fide Holder of a Security  for at least six months may, on behalf of himself and
all others similarly situated,  petition any court of competent jurisdiction for
the removal of the Trustee and the appointment of a successor Trustee.

     (e) If the Trustee shall resign,  be removed or become incapable of acting,

one year after such resignation,  removal or incapability,  or the occurrence of
such vacancy,  a successor Trustee shall be appointed by Act of the Holders of a
majority in aggregate principal amount of the Outstanding  Securities  delivered
to the Company and the  retiring  Trustee,  the  successor  Trustee so appointed
shall,  forthwith upon its acceptance of such appointment,  become the successor
Trustee and  supersede  the successor  Trustee  appointed by the Company.  If no
successor Trustee shall have been so appointed by the Company or the Holders and
accepted appointment in the manner hereinafter provided, the retiring Trustee or
any Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated,  petition any court
of  competent  jurisdiction  for the  appointment  of a successor  Trustee.  The
evidence of such successorship may, but need not be, evidenced by a supplemental
indenture.

     (f) The Company shall give notice of each  resignation  and each removal of
the  Trustee  and each  appointment  of a  successor  Trustee to the  Holders of
Securities in the manner provided for in Section 13.5 hereof.  Each notice shall
include the name of the successor Trustee and the address of its Corporate Trust
Office.

5.9, the Company's  obligations under Section 5.6 shall continue for the benefit
of the retiring Trustee.

     Section 5.10 Acceptance of Appointment by Successor.

     Every successor Trustee appointed hereunder shall execute,  acknowledge and
deliver to the Company and to the retiring Trustee an instrument  accepting such
appointment,  and thereupon the  resignation or removal of the retiring  Trustee
shall become effective and such successor Trustee, without any further act, deed
or  conveyance,  shall  become  vested with all the rights,  powers,  trusts and
duties of the retiring Trustee;  but, on request of the Company or the successor
Trustee,  such retiring Trustee shall,  upon payment of all amounts due it under
Section 5.6  hereof,  execute and  deliver an  instrument  transferring  to such
successor Trustee all the rights,  powers and trusts of the retiring Trustee and
shall duly assign,  transfer and deliver to such successor Trustee all money and
other Property held by such retiring Trustee hereunder. Upon request of any such
successor  Trustee,  the Company shall execute any and all  instruments for more
fully and certainly vesting in and confirming to such successor Trustee all such
rights, powers and trusts.

     No successor  Trustee  shall accept its  appointment  unless at the time of

association resulting from any merger,  conversion or consolidation to which the
Trustee shall be a party, or any corporation or banking  association  succeeding
to all or  substantially  all of the  corporate  trust  business of the Trustee,

banking  association  shall be  otherwise  qualified  and  eligible  under  this
Article,  without the execution or filing of any paper or any further act on the
part of any of the  parties  hereto.  In case any  Securities  shall  have  been
authenticated,  but not delivered,  by the Trustee then in office, any successor
by merger,  conversion or consolidation to such authenticating Trustee may adopt
such  authentication  and deliver the Securities so authenticated  with the same
effect as if such successor  Trustee had itself  authenticated  such Securities;

have been  cured or waived;  provided,  however,  that,  except in the case of a
Default in the payment of the principal of (or premium,  if any, on) or interest
on any Security,  the Trustee shall be protected in  withholding  such notice if
and so long as the  board  of  directors,  the  executive  committee  or a trust
committee of directors and/or Responsible  Officers of the Trustee in good faith
determines  that  the  withholding  of such  notice  is in the  interest  of the
Holders.  The Trustee  shall not be deemed to have notice of any Default,  other
than a Default  under 4.1(a) or (b),  unless the Trustee shall have been advised
in writing that a Default has occurred. No duty imposed upon the Trustee in this
Indenture  shall be applicable  with respect to any Default of which the Trustee
is not deemed to have notice.

other office or agency for one or more of such  purposes.  The Company will give
prompt  written  notice to the Trustee of any change in the location of any such
office or agency.  If at any time the Company  shall fail to  maintain  any such


                                      E-187

<PAGE>


required  office or agency or shall fail to furnish the Trustee with the address

notices and demands.

     The Company may also from time to time  designate one or more other offices
or agencies where the Securities may be presented or surrendered  for any or all
such purposes and may from time to time rescind any such  designation.  Further,
if at any time there  shall be no such  office or agency in The City of New York
where the Securities may be presented or  surrendered  for payment,  the Company
shall  forthwith  designate and maintain such an office or agency in The City of
New York, in order that the Securities shall at all times be payable in The City
of New York.  The Company will give prompt  written notice to the Trustee of any
such  designation or rescission and any change in the location of any such other
office or agency.

     Section 9.3 Money for Security Payments to Be Held in Trust.

     If the Company shall at any time act as its own Paying Agent,  it shall, on
or before 10:00 a.m.,  Eastern  time,  on each due date of the principal of (and
premium, if any, on) or interest on any of the Securities, segregate and hold in
trust for the benefit of the Persons  entitled  thereto a sum  sufficient to pay
the principal  (and premium,  if any) or interest so becoming due until such sum
shall be paid to such  Persons or otherwise  disposed of as herein  provided and
will promptly notify the Trustee of its action or failure so to act.

     Whenever  the  Company  shall  have  one or  more  Paying  Agents  for  the
Securities,  it will on or before 10:00 a.m.,  Eastern time, on each due date of
the  principal of (and  premium,  if any,  on), or interest on, any  Securities,
deposit with a Paying Agent  immediately  available funds in a sum sufficient to
pay the principal (and premium,  if any) or interest so becoming due, such funds
to be held in trust for the benefit of the Persons  entitled to such  principal,
premium or  interest,  and (unless such Paying Agent is the Trustee) the Company
shall promptly notify the Trustee of such action or any failure so to act.

     The  Company  shall  cause each Paying  Agent  (other than the  Trustee) to
execute  and  deliver to the Trustee an  instrument  in which such Paying  Agent
shall agree with the Trustee,  subject to the  provisions of this Section,  that
such Paying Agent will:

     (a) hold all  sums  held by it for the  payment  of the  principal  of (and
premium,  if any, on) or interest on  Securities in trust for the benefit of the
Persons  entitled  thereto  until  such sums  shall be paid to such  Persons  or
otherwise disposed of as herein provided;

     (b) give the  Trustee  notice of any  default by the  Company (or any other
obligor  upon the  Securities)  in the making of any payment of  principal  (and
premium, if any) or interest; and

     (c) at any  time  during  the  continuance  of any such  default,  upon the
written request of the Trustee, forthwith pay to the Trustee all sums so held in
trust by such Paying Agent.

     The Company may at any time, for the purpose of obtaining the  satisfaction
and  discharge of this  Indenture or for any other  purpose,  pay, or by Company
Order  direct any Paying  Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying  Agent,  such sums to be held by the Trustee upon the
same  trusts as those  upon  which  such sums were held by the  Company  or such
Paying Agent;  and,  upon such payment by any Paying Agent to the Trustee,  such
Paying Agent shall be released from all further  liability  with respect to such
sums. The Trustee and each Paying Agent shall promptly pay to the Company,  upon
Company  Request,  any money held by them (other than pursuant to Article XI) at
any time in excess of amounts  required to pay  principal,  premium,  if any, or
interest on the Securities.

     Subject to  applicable  escheat  and  abandoned  property  laws,  any money
deposited with the Trustee or any Paying Agent, or then held by the Company,  in
trust for the payment of the principal of (and premium,  if any, on) or interest
on any Security and remaining  unclaimed for two years after such principal (and
premium,  if any) or interest  has become due and  payable  shall be paid to the
Company on Company Request, or (if then held by the Company) shall be discharged
from  such  trust;  and the  Holder of such  Security  shall  thereafter,  as an
unsecured  general creditor,  look only to the Company for payment thereof,  and
all  liability  of the Trustee or such Paying  Agent with  respect to such trust
money,  and all  liability of the Company as trustee  thereof,  shall  thereupon
cease.

     Section 9.4 Corporate Existence.

     Except as expressly permitted by Article VII hereof, Section 9.16 hereof or
other provisions of this Indenture, the Company shall do or cause to be done all
things  necessary  to preserve  and keep in full force and effect the  corporate
existence, rights (charter and statutory) and franchises of the Company and each
Restricted Subsidiary; provided, however, that the Company shall not be required
to  preserve  any such  existence  of its  Restricted  Subsidiaries,  rights  or
franchises,  if the Board of Directors of the Company shall  determine  that the
preservation  thereof is no longer  desirable  in the conduct of the business of
the Company and its Restricted Subsidiaries, taken as a whole, and that the loss
thereof is not disadvantageous in any material respect to the Holders.

     Section 9.5 Payment of Taxes; Maintenance of Properties; Insurance.

     The  Company  shall  pay or  discharge  or cause to be paid or  discharged,
before the same shall become delinquent, (a) all material taxes, assessments and
governmental  charges  levied or  imposed  upon the  Company  or any  Restricted
Subsidiary  or upon the  income,  profits  or  Property  of the  Company  or any
Restricted  Subsidiary  and (b) all  lawful  claims  for  labor,  materials  and
supplies,  which, if unpaid, might by law become a Lien upon the Property of the
Company or any Restricted Subsidiary;  provided, however, that the Company shall
not be required to pay or discharge or cause to be paid or  discharged  any such
tax,  assessment,  charge or claim whose  amount,  applicability  or validity is
being  contested  in  good  faith  by  appropriate  proceedings  and  for  which
appropriate provision has been made in accordance with GAAP.

     The Company shall cause all material Properties owned by the Company or any
Restricted Subsidiary and used or held for use in the conduct of its business or
the business of any  Restricted  Subsidiary  to be  maintained  and kept in good
condition, repair and working order (ordinary wear and tear excepted), all as in
the judgment of the Company or such  Restricted  Subsidiary  may be necessary so
that its  business may be properly  and  advantageously  conducted at all times;
provided, however, that nothing in this Section shall prevent the Company or any
Restricted  Subsidiary  from  discontinuing  the  maintenance  of  any  of  such
Properties  if such  discontinuance  is, in the  judgment of the Company or such
Restricted  Subsidiary,  as the case may be,  desirable  in the  conduct  of the
business of the Company or such Restricted Subsidiary and not disadvantageous in
any material  respect to the Holders.  Notwithstanding  the  foregoing,  nothing
contained  in this Section 9.5 shall limit or impair in any way the right of the
Company and its Restricted  Subsidiaries to sell, divest and otherwise to engage
in transactions that are otherwise permitted by this Indenture.

     The Company  shall at all times keep all of its,  and cause its  Restricted
Subsidiaries to keep their,  Properties which are of an insurable nature insured
with insurers, believed by the Company to be responsible, against loss or damage
to the extent that property of similar  character  and in a similar  location is
usually  so  insured  by  corporations   similarly   situated  and  owning  like
Properties.

     The  Company  or any  Restricted  Subsidiary  may adopt  such other plan or
method of  protection,  in lieu of or  supplemental  to insurance with insurers,
whether  by the  establishment  of an  insurance  fund or reserve to be held and
applied to make good losses from  casualties,  or  otherwise,  conforming to the


                                      E-189

<PAGE>



systems of self-insurance maintained by corporations similarly situated and in a
similar location and owning like  Properties,  as may be determined by the Board
of Directors of the Company or such Restricted Subsidiary.

     Section 9.6 Limitation on Conduct of Business.

     The  Company  shall  not,  and  shall  not  permit  any of  its  Restricted
Subsidiaries  to,  engage in the conduct of any business  other than the Oil and
Gas Business.

first,  second  and  third  quarters  of each  fiscal  year of the  Company,  an
Officers' Certificate stating that a review of the activities of the Company and
its Restricted  Subsidiaries during the preceding fiscal quarter or fiscal year,
as applicable,  has been made under the supervision of the signing Officers with

fulfilled its obligations under this Indenture,  and further stating, as to each
such  Officer  signing  such  certificate,  that to the  best of such  Officer's
knowledge the Company has kept, observed, performed and fulfilled each and every
condition  and covenant  contained in this  Indenture and no Default or Event of
Default has  occurred  and is  continuing  (or, if a Default or Event of Default
shall have  occurred to either such  Officer's  knowledge,  describing  all such
Defaults or Events of Default of which such Officer may have  knowledge and what
action the  Company is taking or proposes to take with  respect  thereto).  Such
Officers'  Certificate shall comply with TIA Section 314(a)(4).  For purposes of
this Section 9.7(a),  such compliance shall be determined  without regard to any
period of grace or requirement of notice under this Indenture.

     (b) The Company  shall,  so long as any of the  Securities is  outstanding,
deliver to the Trustee,  upon any of its Officers  becoming aware of any Default
or Event of Default, an Officers'  Certificate  specifying such Default or Event
of Default and what action the Company  proposes to take with  respect  thereto,
within 10 days of its occurrence.

     Section 9.8 Provision of Financial Information.

     The Company (and the Subsidiary Guarantors,  if applicable) shall file on a
timely  basis with the SEC,  to the extent  such  filings  are  accepted  by the
Commission  and whether or not the Company has a class of securities  registered
under  the  Exchange  Act,  the  annual  reports,  quarterly  reports  and other
documents  that the  Company  would be  required  to file if it were  subject to
Section  13  or 15  of  the  Exchange  Act.  The  Company  (and  the  Subsidiary
Guarantors, if applicable) shall also file with the Trustee (with exhibits), and
provide to each Holder of Securities  (without  exhibits),  without cost to such
Holder,  copies of such reports and  documents  within 15 days after the date on
which the Company  (and the  Subsidiary  Guarantors,  if  applicable)  file such
reports and documents  with the Commission or the date on which the Company (and
the Subsidiary Guarantors, if applicable) would be required to file such reports
and  documents if the Company  were so required  and, if filing such reports and
documents with the Commission is not accepted by the Commission or is prohibited
under the  Exchange  Act,  the Company  shall  supply at its cost copies of such
reports  and  documents  (including  any  exhibits  thereto)  to any  Holder  of
Securities  promptly upon written  request given in accordance with Section 13.4
hereof. The Company is obligated to make available,  upon request, to any Holder
of Securities the information  required by Rule 144A(d)(4)  under the Securities
Act,  during  any period in which the  Company  is not  subject to Section 13 or

         Indebtedness  does  not  exceed  the  principal  amount  (or,  if  such
         Subordinated  Indebtedness being refinanced provides for an amount less
         than  the  principal  amount  thereof  to be  due  and  payable  upon a
         declaration of acceleration  thereof, such lesser amount as of the date
         of determination) of the Subordinated  Indebtedness being so purchased,
         redeemed, repaid, defeased, acquired or retired, plus the amount of any
         premium  required  to be  paid  in  connection  with  such  refinancing

          Subordinated  Indebtedness so purchased,  redeemed,  repaid, defeased,
          acquired or retired, and (C) such new Indebtedness has an Average Life
          to Stated  Maturity  that is longer  than the  Average  Life to Stated
          Maturity  of the  Securities  and such new  Indebtedness  has a Stated
          Maturity for its final scheduled principal payment that is at least 91

         of  the  Company  in an  aggregate  amount  not  to  exceed  $1,000,000
         outstanding  at any one time, the proceeds of which are used solely (A)
         to purchase common stock of the Company in connection with a restricted
         stock or employee  stock  purchase  plan, or to exercise  stock options
         received pursuant to an employee or director stock option plan or other

         of such stock options or (B) to refinance loans,  together with accrued

          The actions  described in clauses (i), (ii),  (iii),  (iv) and (vi) of
this  paragraph (b) shall be  Restricted  Payments that shall be permitted to be
made in  accordance  with this  paragraph  (b) but shall  reduce the amount that
would  otherwise  be  available  for  Restricted  Payments  under  clause (3) of
paragraph  (a)  (provided  that any dividend paid pursuant to clause (i) of this
paragraph  (b) shall reduce the amount that would  otherwise be available  under
clause (3) of paragraph (a) when declared,  but not also when  subsequently paid
pursuant to such clause (i)),  and the actions  described in clause (iv) of this
paragraph (b) shall be permitted to be taken in accordance  with this  paragraph
and shall not reduce the amount that would otherwise be available for Restricted

Company shall use audited financial  statements for the portions of the relevant
period for which  audited  financial  statements  are  available  on the date of
determination  and unaudited  financial  statements and other current  financial
data based on the books and records of the Company for the remaining  portion of
such period and (2) the Company  shall be permitted to rely in good faith on the
financial statements and other financial data derived from the books and records
of the Company that are available on the date of  determination.  If the Company
makes a Restricted  Payment which,  at the time of the making of such Restricted
Payment would in the good faith  determination of the Company be permitted under
the requirements of this Indenture,  such Restricted  Payment shall be deemed to
have been made in compliance with this Indenture  notwithstanding any subsequent
adjustments made in good faith to the Company's financial  statements  affecting
Consolidated Net Income of the Company for any period.

     Section 9.10 Limitation on Guarantees by Subsidiary Guarantors.

         The Company shall not permit any Subsidiary  Guarantor to guarantee the
payment of any  Subordinated  Indebtedness  of the Company unless such guarantee
shall be  subordinated to such Subsidiary  Guarantor's  Subsidiary  Guarantee at
least to the same extent as such  Subordinated  Indebtedness  is subordinated to
the  Securities;  provided,  however,  that  this  Section  9.10  shall  not  be
applicable to any guarantee of any Subsidiary  Guarantor that (i) existed at the
time such Person became a Subsidiary of the Company and (ii) was not incurred in
connection with, or in contemplation  of, such Person's becoming a Subsidiary of
the Company.

Restricted Subsidiaries to, issue any Disqualified Capital Stock (except for the
issuance by the Company of (A) 1,948,001  shares of Series A Preferred Stock and

in accordance with their terms) and (B) Disqualified  Capital Stock (1) which is
redeemable  at the Company's  option in cash or Qualified  Capital Stock and (2)

Subsidiaries  that are  Subsidiary  Guarantors may incur  Indebtedness  or issue
shares of Disqualified  Capital Stock if (i) at the time of such event and after
giving  effect  thereto  on a pro forma  basis  the  Consolidated  Fixed  Charge
Coverage  Ratio for the four full  quarters  immediately  preceding  such event,
taken as one  period,  would have been  equal to or greater  than 2.5 to 1.0 and

determining  compliance with this Section 9.11(a),  in the event that an item of
Indebtedness  meets the criteria of one or more of the  categories  of Permitted
Indebtedness  described  in clauses (i) through  (xi) of such  definition  or is
entitled  to be incurred  (whether  incurred  under the Bank Credit  Facility or
otherwise) pursuant to the proviso of the foregoing  sentence,  the Company may,
in its sole  discretion,  classify such item of  Indebtedness in any manner that
complies  with this  covenant and such item of  Indebtedness  will be treated as
having been incurred  pursuant too only one of such clauses of the definition of
Permitted  Indebtedness or the proviso of the foregoing  sentence and an item of
Indebtedness  may be  divided  and  classified  in more than one of the types of
Indebtedness permitted hereunder.

     (b) The amount of any guarantee by the Company or any Restricted Subsidiary
of any Indebtedness of the Company or one or more Restricted  Subsidiaries shall
not be deemed to be  outstanding  or incurred  for purposes of this Section 9.11
hereof in addition to the amount of Indebtedness which it guarantees.

     (c) For  purposes of this  Section  9.11,  Indebtedness  of any Person that
becomes a Restricted  Subsidiary by merger,  consolidation or other  acquisition
shall  be  deemed  to have  been  incurred  by the  Company  and the  Restricted
Subsidiary at the time such Person becomes a Restricted Subsidiary.

     Section 9.12 Additional Subsidiary Guarantors.

     (a) The Company shall cause each  Restricted  Subsidiary  that becomes,  or
comes  into  existence  as,  a  Restricted  Subsidiary  after  the  date of this
Indenture and has assets, businesses, divisions, real property or equipment with
a  Fair  Market  Value  in  excess  of  $5,000,000  to  execute  and  deliver  a
supplemental  indenture  to this  Indenture  agreeing  to be bound by its  terms
applicable to a Subsidiary Guarantor and providing for a Subsidiary Guarantee of
the Securities by such Restricted Subsidiary.

     (b)  Notwithstanding  the  foregoing  and  the  other  provisions  of  this
Indenture, any Subsidiary Guarantee incurred by a Restricted Subsidiary pursuant
to this Section 9.12 shall  provide by its terms that it shall be  automatically
and  unconditionally  released and discharged  upon the terms and conditions set
forth in Section 12.3 hereof.

     Section  9.13  Limitation  on  Issuances  and  Sales  of  Capital  Stock by

                                      E-194

the time such Restricted  Subsidiary became a Restricted  Subsidiary or acquired
by such Person in connection with the formation of the Restricted Subsidiary, or
transfers  thereof or (iii) a sale of all of the Capital  Stock of a  Restricted

Capital Stock of a Foreign  Subsidiary that is required to be issued to or owned
by the government of a foreign  jurisdiction or individual or corporate citizens
of such foreign  jurisdiction  in order for such Foreign  Subsidiary to transact
business in such foreign jurisdiction,  provided, that any such sale or issuance
shall be deemed to be an Asset Sale to the extent  the  percentage  of the total
outstanding   Voting  Stock  of  such  Foreign  Subsidiary  owned  directly  and
indirectly  by the Company is reduced as a result of such sale or  issuance  and
any such sale or issuance  must be made in  compliance  with the  provisions  of
Section 9.16 hereof.

     Section 9.14 Limitation on Liens.

     The Company shall not, and shall not permit any  Restricted  Subsidiary to,

their  respective  Properties,  whether now owned or acquired  after the date of
this  Indenture,  or any  income or profits  therefrom,  or assign or convey any
right to receive  income  thereon,  unless (a) in the case of any Lien  securing
Subordinated Indebtedness, the Securities are secured by a lien on such Property
or  proceeds  that is senior in priority to such Lien and (b) in the case of any
other Lien,  the Securities  are directly  secured  equally and ratably with the
obligation or liability secured by such Lien.

     Section 9.15 Purchase of Securities Upon Change of Control.

     (a) Upon the  occurrence  of a Change  of  Control,  the  Company  shall be
obligated to make an offer to purchase (a "Change of Control  Offer") all of the
then  Outstanding  Securities,  in whole or in part,  from the  Holders  of such
Securities in integral  multiples of $1,000, at a purchase price (the "Change of
Control Purchase Price") equal to 101% of the aggregate principal amount of such
Securities,  plus accrued and unpaid interest,  if any, to the Change of Control
Purchase Date (as defined below), in accordance with the procedures set forth in
paragraphs (b), (c) and (d) of this Section.  The Company shall,  subject to the
provisions  described  below,  be required to purchase all  Securities  properly
tendered  into the Change of Control Offer and not  withdrawn.  The Company will
not be  required  to make a Change of Control  Offer upon a Change of Control if
another Person makes the Change of Control Offer at the same purchase  price, at
the same times and otherwise in  substantial  compliance  with the  requirements
applicable  to a Change of Control Offer to be made by the Company and purchases
all Securities  validly  tendered and not withdrawn under such Change of Control
Offer.

     (b) The Change of Control  Offer is required to remain open for at least 20
Business Days and until the close of business on the fifth Business Day prior to
the Change of Control Purchase Date (as defined below).

     (c) Not  later  than the 30th day  following  any  Change of  Control,  the
Company  shall give to the Trustee in the manner  provided  in Section  13.4 and
each Holder of the  Securities in the manner  provided in Section 13.5, a notice
(the "Change of Control  Notice")  governing  the terms of the Change of Control
Offer and stating:

          (1) that a Change in Control has occurred and that such Holder has the
     right to require the Company to  repurchase  such Holder's  Securities,  or
     portion thereof, at the Change of Control Purchase Price;

          (2) any  information  regarding such Change of Control  required to be
     furnished  pursuant  to Rule  13e-1  under the  Exchange  Act and any other
     securities laws and regulations thereunder;


                                      E-195

<PAGE>



          (3) a purchase  date (the  "Change of Control  Purchase  Date")  which
     shall be on a Business  Day and no  earlier  than 30 days nor later than 60
     days from the date the Change of Control occurred;

          (4) that any Security,  or portion  thereof,  not tendered or accepted
     for payment will continue to accrue interest:

          (5) that unless the  Company  defaults  in  depositing  money with the
     Paying Agent in  accordance  with the last  paragraph of clause (d) of this
     Section 9.15, or payment is otherwise prevented,  any Security,  or portion
     thereof, accepted for payment pursuant to the Change of Control Offer shall
     cease to accrue interest after the Change of Control Purchase Date; and

          (6) the  instructions  a  Holder  must  follow  in  order  to have his
     Securities repurchased in accordance with paragraph (d) of this Section.

If any of the  Securities  subject to the Change of Control Offer is in the form
of a Global Security, then the Company shall modify the Change of Control Notice
to the  extent  necessary  to  accord  with  the  procedures  of the  depository
applicable thereto.

     (d)  Holders  electing  to have  Securities  purchased  will be required to
surrender  such  Securities to the Paying Agent at the address  specified in the
Change of  Control  Notice at least  five  Business  Days prior to the Change of
Control  Purchase  Date.  Holders will be entitled to withdraw their election if
the Paying  Agent  receives,  not later than  three  Business  Days prior to the
Change of Control Purchase Date, a telegram,  telex,  facsimile  transmission or
letter  setting  forth  the  name of the  Holder  and  principal  amount  of the
Securities  delivered  for purchase by the Holder as to which his election is to
be withdrawn  and a statement  that such Holder is  withdrawing  his election to
have such Securities  purchased.  Holders whose Securities are purchased only in
part will be issued new Securities  equal in principal amount to the unpurchased
portion of the Securities surrendered.

     On the Change of Control  Purchase  Date,  the Company shall (i) accept for
payment  Securities or portions thereof validly tendered pursuant to a Change of
Control  Offer,  (ii) deposit with the Paying Agent money  sufficient to pay the
purchase  price of all  Securities  or portions  thereof so tendered,  and (iii)
deliver or cause to be delivered to the Trustee the Securities so accepted.  The
Paying  Agent shall  promptly  mail or deliver to Holders of the  Securities  so
tendered  payment in an amount equal to the purchase  price for the  Securities,
and the Company  shall execute and the Trustee  shall  authenticate  and mail or
make  available  for delivery to such Holders a new Security  equal in principal
amount to any unpurchased  portion of the Security which any such Holder did not
surrender  for purchase.  The Company shall  announce the results of a Change of
Control Offer on or as soon as practicable  after the Change of Control Purchase
Date.  For  purposes of this  Section  9.15,  the Trustee will act as the Paying
Agent.

     (e) The Company shall comply with Rule 14e-1 under the Exchange Act and any
other  securities  laws and  regulations  thereunder to the extent such laws and
regulations are applicable, in the event that a Change of Control occurs and the
Company is required to purchase Securities as described in this Section 9.15.

     Section 9.16 Limitation on Asset Sales.

     (a) The  Company  shall not,  and shall not  permit  any of its  Restricted
Subsidiaries  to,  consummate  any Asset  Sale  unless  (i) the  Company or such
Restricted Subsidiary, as the case may be, receives consideration at the time of
such Asset Sale at least equal to the Fair Market Value of the Property  subject
to such Asset Sale and (ii) all of the consideration paid to the Company or such
Restricted Subsidiary in connection with such Asset Sale is in the form of cash,


                                      E-196

<PAGE>


Cash Equivalents,  Liquid Securities,  Exchanged Properties or the assumption by
the  purchaser of  liabilities  of the Company  (other than  liabilities  of the
Company that are by their terms  subordinated  to the Securities) or liabilities
of any Subsidiary Guarantor that made such Asset Sale (other than liabilities of
a Subsidiary  Guarantor that are by their terms  subordinated to such Subsidiary
Guarantor's Subsidiary Guarantee), in each case as a result of which the Company
and  its  remaining  Restricted  Subsidiaries  are no  longer  liable  for  such
liabilities ("Permitted Consideration"); provided, however, that the Company and
its Restricted  Subsidiaries  shall be permitted to receive  Property other than
Permitted Consideration,  so long as the aggregate Fair Market Value of all such
Property other than Permitted  Consideration  received from Asset Sales and held
by the  Company or any  Restricted  Subsidiary  at any one time shall not exceed
7.5% of Adjusted  Consolidated Net Tangible Assets.  The Net Available Cash from
Asset  Sales by the  Company or a  Restricted  Subsidiary  may be applied by the
Company  or such  Restricted  Subsidiary,  to the  extent  the  Company  or such
Restricted  Subsidiary  elects  (or is  required  by  the  terms  of any  Senior
Indebtedness  of  the  Company  or  a  Subsidiary   Guarantor),   to  (i)  repay
Indebtedness  of the Company  under the Bank Credit  Facility,  (ii) reinvest in
Additional Assets (including by means of an Investment in Additional Assets by a
Restricted Subsidiary with Net Available Cash received by the Company or another
Restricted  Subsidiary) or (iii) purchase Securities or purchase both Securities
and one or more  series  or issues of other  Senior  Indebtedness  on a pro rata
basis (excluding  Securities and Senior  Indebtedness owned by the Company or an
Affiliate of the Company).  Pending any reinvestment  pursuant to clause (ii) in
the preceding sentence,  the Company may temporarily  prepay,  repay or purchase
Senior Indebtedness of the Company or a Subsidiary Guarantor.

     (b) Any Net  Available  Cash from an Asset Sale not  applied in  accordance
with the  preceding  paragraph  within 365 days from the date of such Asset Sale
shall constitute "Excess Proceeds." When the aggregate amount of Excess Proceeds
exceeds $10,000,000,  the Company shall be required to make an offer to purchase
Securities having an aggregate principal amount equal to the aggregate amount of
Excess  Proceeds (the  "Prepayment  Offer") at a purchase price equal to 100% of
the principal  amount of such  Securities plus accrued and unpaid  interest,  if
any,  to the  Purchase  Date (as  defined)  in  accordance  with the  procedures
(including prorating in the event of oversubscription)  set forth herein. If the
aggregate principal amount of Securities tendered by Holders thereof exceeds the
amount  of  available  Excess  Proceeds,  then  such  Excess  Proceeds  shall be
allocated pro rata according to the principal amount of the Securities  tendered
and the Trustee  shall  select the  Securities  to be  purchased  in  accordance
herewith.  To the  extent  that any  portion  of the  amount of Excess  Proceeds
remains after compliance with the second sentence of this paragraph and provided
that all Holders of Securities  have been given the  opportunity to tender their
Securities  for purchase as described in the  following  paragraph in accordance
with this Indenture,  the Company and its Restricted  Subsidiaries  may use such
remaining  amount for  purposes  permitted by this  Indenture  and the amount of
Excess Proceeds shall be reset to zero.

     (c) (1) Within 30 days after the 365th day  following  the date of an Asset
Sale,  the Company  shall,  if it is  obligated to make an offer to purchase the
Securities pursuant to the preceding paragraph,  send a written Prepayment Offer
notice,  by  first-class  mail, to the Trustee and the Holders of the Securities
(the "Prepayment Offer Notice"),  accompanied by such information  regarding the
Company and its  Subsidiaries as the Company  believes shall enable such Holders
of the  Securities to make an informed  decision with respect to the  Prepayment
Offer  (which at a minimum  shall  include (i) the most  recently  filed  Annual
Report on Form 10-K (including audited consolidated financial statements) of the
Company, the most recent subsequently filed Quarterly Report on Form 10-Q of the
Company and any Current  Report on Form 8-K of the Company  filed  subsequent to
such  Quarterly  Report,  other than  Current  Reports  describing  Asset  Sales
otherwise  described  in the  offering  materials,  or  corresponding  successor
reports  (or,  during any time that the Company is not subject to the  reporting
requirements of Section 13 or 15(d) of the Exchange Act,  corresponding  reports
prepared  pursuant to Section 9.8), (ii) a description of material  developments
in the Company's  business  subsequent to the date of the latest of such reports
and  (iii) if  material,  appropriate  pro  forma  financial  information).  The
Prepayment Offer Notice shall state, among other things, (i) that the Company is
offering to purchase  Securities  pursuant to the provisions of this  Indenture,
(ii) that any Security (or any portion  thereof)  accepted for payment (and duly


                                      E-197

<PAGE>


paid on the  Purchase  Date)  pursuant  to the  Prepayment  Offer shall cease to
accrue  interest on the Purchase  Date,  (iii) that any  Securities (or portions
thereof) not  properly  tendered  shall  continue to accrue  interest,  (iv) the
purchase  price and  purchase  date,  which  shall be,  subject to any  contrary
requirements of applicable law, no less than 30 days nor more than 60 days after
the date the Prepayment  Offer Notice is mailed (the "Purchase  Date"),  (v) the
aggregate principal amount of Securities to be purchased,  (vi) a description of
the procedure  which Holders of Securities  must follow in order to tender their
Securities and the procedures that Holders of Securities must follow in order to
withdraw an election to tender their  Securities for payment and (vii) all other
instructions  and  materials  necessary to enable  Holders to tender  Securities
pursuant to the Prepayment Offer.

          (2) Not later than the date upon which written  notice of a Prepayment
     Offer is  delivered  to the Trustee as provided  above,  the Company  shall
     deliver to the Trustee an Officers' Certificate as to (i) the amount of the
     Prepayment  Offer (the  "Offer  Amount"),  (ii) the  allocation  of the Net
     Available Cash from the Asset Sales pursuant to which such Prepayment Offer
     is  being  made  and  (iii)  the  compliance  of such  allocation  with the
     provisions  of  Section  9.16(a).  On such  date,  the  Company  shall also
     irrevocably  deposit  with the Trustee or with the Paying Agent (or, if the
     Company is the Paying Agent,  shall segregate and hold in trust) in cash an
     amount equal to the Offer Amount to be held for payment in accordance  with
     the provisions of this Section. Upon the expiration of the period for which
     the Prepayment Offer remains open (the "Offer  Period"),  the Company shall
     deliver to the Trustee for  cancellation the Securities or portions thereof
     which have been properly tendered to and are to be accepted by the Company.
     The  Trustee or the Paying  Agent  shall,  on the  Purchase  Date,  mail or
     deliver  payment to each  tendering  Holder in the  amount of the  purchase
     price.  In the event that the aggregate  purchase  price of the  Securities
     delivered by the Company to the Trustee is less than the Offer Amount,  the
     Trustee  or the  Paying  Agent  shall  deliver  the  excess to the  Company
     immediately  after the  expiration of the Offer Period for  application  in
     accordance with this Section.

          (3) Holders electing to have a Security purchased shall be required to
     surrender the Security,  with an appropriate  form duly  completed,  to the
     Company or its agent at the address  specified in the notice at least three
     Business  Days prior to the  Purchase  Date.  Holders  shall be entitled to
     withdraw  their  election if the Trustee or the Company  receives not later
     than one  Business  Day prior to the  Purchase  Date,  a  telegram,  telex,
     facsimile  transmission or letter setting forth the name of the Holder, the
     principal  amount of the Security  which was  delivered for purchase by the
     Holder and a statement that such Holder is withdrawing his election to have
     such  Security  purchased.  If at the  expiration  of the Offer  Period the
     aggregate principal amount of Securities surrendered by Holders exceeds the
     Offer Amount,  the Company shall select the Securities to be purchased on a
     pro rata basis (with such  adjustments as may be deemed  appropriate by the
     Company so that only  Securities in  denominations  of $1,000,  or integral
     multiples  thereof,  shall be  purchased).  Holders  whose  Securities  are
     purchased  only in part shall be issued new  Securities  equal in principal
     amount to the unpurchased portion of the Securities surrendered.

          (4) At the time the Company  delivers  Securities to the Trustee which
     are to be  accepted  for  purchase,  the  Company  shall  also  deliver  an
     Officers'  Certificate  stating that such  Securities are to be accepted by
     the Company  pursuant to and in  accordance  with the terms of this Section
     9.16. A Security  shall be deemed to have been accepted for purchase at the
     time the Trustee or the Paying Agent mails or delivers  payment therefor to
     the surrendering Holder.

     (d)  The  Company  shall  comply,  to  the  extent  applicable,   with  the
requirements of Rule 14e-1 under the Exchange Act and any other  securities laws
or regulations thereunder to the extent such laws and regulations are applicable
in connection with the purchase of Securities as described  above. To the extent
that the  provisions of any  securities  laws or  regulations  conflict with the
provisions  relating to the Prepayment  Offer, the Company shall comply with the

the sale,  purchase,  exchange  or lease of  Property  or the  rendering  of any
services)  with, or for the benefit of, any Affiliate of the Company (other than
the  Company  or  a  Wholly  Owned  Restricted  Subsidiary),   unless  (a)  such
transaction  or  series of  related  transactions  is on terms  that are no less
favorable to the Company or such Restricted Subsidiary, as the case may be, than
would be available in a comparable  transaction in arm's-length dealings with an
unrelated  third party,  (b) with respect to a transaction  or series of related
transactions  involving aggregate payments in excess of $2,500,000,  the Company
delivers  an  Officers'   Certificate  to  the  Trustee   certifying  that  such
transaction or series of related transactions complies with clause (a) above and

majority of the Disinterested  Directors of the Company, and (c) with respect to
any one  transaction  or  series of  related  transactions  involving  aggregate
payments in excess of  $10,000,000,  the  Officers'  Certificate  referred to in
clause (b) above also certifies that the Company has obtained a written  opinion
from an independent  nationally  recognized investment banking firm or appraisal
firm  specializing  or having a speciality in the type and subject matter of the
transaction or series of related  transactions at issue,  which opinion shall be
to the effect set forth in clause (a) above or shall state that such transaction
or series of related  transactions is fair from a financial point of view to the
Company or such Restricted  Subsidiary;  provided,  however,  that the foregoing
restriction shall not apply to (i) loans or advances to officers,  directors and
employees  of the  Company or any  Restricted  Subsidiary  made in the  ordinary
course of business in an aggregate amount not to exceed  $1,000,000  outstanding
at any one time, (ii)  indemnities of officers,  directors,  employees and other
agents of the  Company  or any  Restricted  Subsidiary  permitted  by  corporate
charter or other organizational document,  bylaw or statutory provisions,  (iii)
the payment of reasonable  and customary fees to directors of the Company or any
of its  Restricted  Subsidiaries  who are not  employees  of the  Company or any
Affiliate,   (iv)  the  Company's   employee   compensation  and  other  benefit
arrangements,  (v) transactions exclusively between or among the Company and any

Indenture, and (vi) any Restricted Payment permitted to be paid pursuant Section
9.9.

     Section  9.18  Limitation  on  Dividends  and  Other  Payment  Restrictions
                    Affecting Restricted Subsidiaries.

     The Company shall not, and shall not permit any  Restricted  Subsidiary to,
directly or indirectly,  create or suffer to exist or allow to become  effective
any  consensual  encumbrance  or  restriction  of any kind on the ability of any
Restricted  Subsidiary to (a) pay dividends,  in cash or otherwise,  or make any
other  distributions  on or in respect of its Capital Stock, or make payments on
any Indebtedness owed, to the Company or any other Restricted Subsidiary, (b) to
make loans or advances to the Company or any other Restricted  Subsidiary or (c)
to  transfer  any of  its  Property  to the  Company  or  any  other  Restricted
Subsidiary (any such  restrictions  being  collectively  referred to herein as a
"Payment  Restriction"),  except for such encumbrances or restrictions  existing
under  or by  reason  of (i)  customary  provisions  restricting  subletting  or
assignment  of any lease  governing a  leasehold  interest of the Company or any
Restricted  Subsidiary,  or customary  restrictions in licenses  relating to the
Property  covered  thereby and entered into in the ordinary  course of business,
(ii) any instrument  governing  Indebtedness of a Person acquired by the Company
or any Restricted Subsidiary at the time of such acquisition,  which encumbrance
or restriction is not applicable to any other Person,  other than the Person, or
the Property of the Person, so acquired, provided that such Indebtedness was not
incurred in anticipation  of such  acquisition or (iii) the Bank Credit Facility
as in  effect  on the  date of this  Indenture  or any  agreement  that  amends,
modifies,  supplements,  restates,  extends, renews,  refinances or replaces the
Bank Credit  Facility,  provided  that the terms and  conditions  of any Payment
Restriction  thereunder are not materially  less favorable to the Holders of the

     Section 9.19 Limitation on Sale and Leaseback Transactions.

     The  Company  will  not,  and  will  not  permit  any  of  its   Restricted
Subsidiaries  to,  enter  into any  Sale/Leaseback  Transaction  unless  (i) the
Company  or such  Restricted  Subsidiary,  as the case may be,  would be able to
incur  Indebtedness  in an amount equal to the  Attributable  Indebtedness  with
respect  to  such  Sale/Leaseback  Transaction  or  (ii)  the  Company  or  such
Restricted Subsidiary receives proceeds from such Sale/Leaseback  Transaction at
least equal to the fair market value thereof (as determined in good faith by the
Company's Board of Directors,  whose determination in good faith, evidenced by a
resolution of such Board shall be  conclusive)  and such proceeds are applied in
the same manner and to the same extent as Net Available Cash and Excess Proceeds
from an Asset Sale.

     Section 9.20 Waiver of Certain Covenants.

     The  Company may omit in any  particular  instance to comply with any term,
provision or condition set forth in Sections 9.5 through 9.11, Sections 9.13 and
9.14 and Sections 9.17 through 9.19 hereof if, before or after the time for such
compliance,  the Holders of at least a majority in aggregate principal amount of
the Outstanding Securities and the Subsidiary Guarantors, by Act of such Holders
and written  agreement of the Subsidiary  Guarantors,  waive such  compliance in
such instance with such term,  provision or condition,  but no such waiver shall
extend to or affect such term,  provision or  condition  except to the extent so
expressly waived, and, until such waiver shall become effective, the obligations
of the  Company  and the  duties of the  Trustee  in  respect  of any such term,
provision or condition shall remain in full force and effect.

                                   ARTICLE X.

                            REDEMPTION OF SECURITIES

     Section 10.1 Notice to Trustee.

     If the Company elects to redeem  Securities  pursuant to paragraph 5 of the
Securities,  it shall notify the Trustee in writing of the redemption  date, the
principal  amount of Securities to be redeemed and that such redemption is being
made pursuant to paragraph 5 of the Securities.

     The  Company  shall give each notice to the  Trustee  provided  for in this
Section at least 60 days before the Redemption Date unless the Trustee  consents
to  a  shorter  period.  Such  notice  shall  be  accompanied  by  an  Officers'
Certificate  and an Opinion of Counsel  from the Company to the effect that such
redemption  will  comply  with the  conditions  herein.  Any  election to redeem
Securities  shall be revocable  until the Company  gives a notice of  redemption
pursuant to Section 10.2 to the Holders of Securities to be redeemed.

     Section 10.2 Selection by Trustee of Securities to Be Redeemed.

     If  less  than  all  the  Securities  are to be  redeemed,  the  particular
Securities to be redeemed  shall be selected not less than 30 days nor more than
60 days  prior to the  Redemption  Date by the  Trustee,  from  the  Outstanding
Securities  not  previously  called for  redemption,  pro rata, by lot or by any
other  method  as the  Trustee  shall  deem fair and  appropriate  and which may
provide  for the  selection  for  redemption  of portions  of the  principal  of
Securities;  provided,  however,  that any such partial  redemption  shall be in
integral multiples of $1,000.

     The Trustee shall promptly  notify the Company in writing of the Securities
selected for redemption and, in the case of any Securities  selected for partial
redemption, the principal amount thereof to be redeemed.


                                      E-200

<PAGE>



     For all purposes of this Indenture,  unless the context otherwise requires,
all provisions relating to redemption of Securities shall relate, in the case of
any  Security  redeemed  or to be redeemed  only in part,  to the portion of the
principal amount of such Security which has been or is to be redeemed.

     Section 10.3 Notice of Redemption.

     Notice of redemption  shall be given in the manner  provided for in Section
13.5 hereof not less than 30 nor more than 60 days prior to the Redemption Date,
to each Holder of Securities to be redeemed.

     All notices of redemption shall state:

     (a) the Redemption Date;

     (b) the Redemption Price;

     (c) if  less  than  all  Outstanding  Securities  are to be  redeemed,  the
identification (and, in the case of a partial redemption, the principal amounts)
of the particular Securities to be redeemed;

     (d) that on the Redemption Date the Redemption Price (together with accrued
interest,  if any, to the  Redemption  Date  payable as provided in Section 10.5
hereof)  will become due and  payable  upon each such  Security,  or the portion
thereof,  to be  redeemed,  and that,  unless the Company  shall  default in the
payment of the Redemption Price and any applicable  accrued  interest,  interest
thereon will cease to accrue on and after said date; and

     (e) the place or places where such  Securities  are to be  surrendered  for
payment of the Redemption Price.

     Notice of  redemption  of  Securities to be redeemed at the election of the
Company  shall be given by the  Company  or, at the  Company's  request,  by the
Trustee  in the name and at the  expense  of the  Company.  Failure to give such
notice by mailing to any Holder of  Securities  or any defect  therein shall not
affect the validity of any proceedings for the redemption of other Securities.

     Section 10.4 Deposit of Redemption Price.

     On or before 10:00 a.m.,  Eastern time, on any Redemption Date, the Company
shall  deposit  with the  Trustee or with a Paying  Agent (or, if the Company is
acting as its own  Paying  Agent,  segregate  and hold in trust as  provided  in
Section 9.3 hereof) an amount of money  sufficient to pay the  Redemption  Price
of, and  accrued  and unpaid  interest  on, all the  Securities  which are to be
redeemed on such Redemption Date.

     Section 10.5 Securities Payable on Redemption Date.

     Notice of redemption  having been given as aforesaid,  the Securities so to
be  redeemed  shall,  on the  Redemption  Date,  become  due and  payable at the
Redemption Price therein  specified  (together with accrued and unpaid interest,
if any,  to the  Redemption  Date),  and from and after  such date  (unless  the
Company  shall  default in the payment of the  Redemption  Price and accrued and
unpaid interest) such Securities shall cease to bear interest. Upon surrender of
any such Security for redemption in accordance  with said notice,  such Security
shall be paid by the Company at the Redemption Price,  together with accrued and
unpaid interest, if any, to the Redemption Date.

     If any Security  called for redemption  shall not be so paid upon surrender
thereof for redemption,  the principal (and premium,  if any) shall, until paid,
bear interest from the Redemption Date at the rate borne by the Securities.

     Section 10.6 Securities Redeemed in Part.

     Any Security  which is to be redeemed only in part shall be  surrendered at
the office or agency of the  Company  maintained  for such  purpose  pursuant to
Section  9.2 hereof  (with,  if the  Company or the  Trustee  so  requires,  due
endorsement by, or a written  instrument of transfer in form satisfactory to the
Company and the Trustee duly  executed by, the Holder  thereof or such  Holder's
attorney duly  authorized in writing),  and the Company shall  execute,  and the
Trustee shall  authenticate  and deliver to the Holder of such Security  without
service charge, a new Security or Securities,  of any authorized denomination as
requested by such Holder, in aggregate principal amount equal to and in exchange
for  the  unredeemed  portion  of  the  principal  amount  of  the  Security  so
surrendered.

                                   ARTICLE XI.

                       DEFEASANCE AND COVENANT DEFEASANCE

     Section 11.1 Company's Option to Effect Defeasance or Covenant Defeasance.

     The  Company  may,  at its option by Board  Resolution,  at any time,  with
respect to the  Securities,  elect to have either  Section  11.2 or Section 11.3
hereof  be  applied  to all  Outstanding  Securities  upon  compliance  with the
conditions set forth below in this Article XI.

     Section 11.2 Defeasance and Discharge.

     Upon the  Company's  exercise  under  Section  11.1  hereof  of the  option
applicable to this Section 11.2, the Company and the Subsidiary Guarantors shall
be deemed to have been discharged from their respective obligations with respect
to all  Outstanding  Securities on the date the  conditions set forth in Section
11.4 hereof are satisfied (hereinafter,  "legal defeasance").  For this purpose,
such legal defeasance means that the Company and the Subsidiary Guarantors shall
be deemed (i) to have paid and discharged their respective obligations under the
Outstanding Securities; provided, however, that the Securities shall continue to
be deemed to be "Outstanding"  for purposes of Section 11.5 hereof and the other
Sections of this Indenture referred to in clauses (A) and (B) below, and (ii) to
have satisfied all their other  obligations  with respect to such Securities and
this  Indenture  (and the Trustee,  at the expense and direction of the Company,
shall  execute  proper  instruments  acknowledging  the  same),  except  for the
following  which  shall  survive  until   otherwise   terminated  or  discharged
hereunder:  (A) the rights of  Holders of  Outstanding  Securities  to  receive,
solely from the trust fund  described  in Section  11.4 hereof and as more fully
set forth in such Section,  payments in respect of the principal of (and premium
if any, on) and interest on such  Securities  when such  payments are due (or at
such time as the Securities  would be subject to redemption at the option of the
Company in accordance with this  Indenture),  (B) the respective  obligations of
the Company and the  Subsidiary  Guarantors  under  Sections 2.3, 2.4, 2.5, 2.6,
2.7, 2.8,  2.9, 4.8,  4.14,  5.6,  5.9,  5.10,  9.2, 9.3, 12.1 (to the extent it
relates to the  foregoing  Sections and this Article XI),  12.4 and 12.5 hereof,
(C) the rights,  powers, trusts, duties and immunities of the Trustee hereunder,
and (D) the obligations of the Company and the Subsidiary  Guarantors under this
Article XI. Subject to compliance with this Article XI, the Company may exercise
its option  under this Section 11.2  notwithstanding  the prior  exercise of its
option under Section 11.3 hereof with respect to the Securities.

     Section 11.3 Covenant Defeasance.

     Upon the  Company's  exercise  under  Section  11.1  hereof  of the  option
applicable to this Section 11.3, the Company and each Subsidiary Guarantor shall
be released from their respective  obligations  under any covenant  contained in
Article  VII,  in  Sections  9.5  through  9.19 and in Section  12.2 hereof with
respect to the  Outstanding  Securities on and after the date the conditions set
forth  below  are  satisfied  (hereinafter,   "covenant  defeasance"),  and  the
Securities shall  thereafter be deemed not to be "Outstanding"  for the purposes


                                      E-202

<PAGE>


of any  direction,  waiver,  consent or  declaration  or Act of Holders (and the
consequences  of any  thereof)  in  connection  with such  covenants,  but shall
continue to be deemed  "Outstanding" for all other purposes hereunder.  For this
purpose,  such covenant  defeasance  means that, with respect to the Outstanding
Securities,  the Company and each  Subsidiary  Guarantor may omit to comply with
and shall have no liability in respect of any term,  condition or limitation set
forth in any such covenant,  whether  directly or  indirectly,  by reason of any
reference elsewhere herein to any such covenant or by reason of any reference in
any such  covenant to any other  provision  herein or in any other  document and
such  omission to comply  shall not  constitute a Default or an Event of Default
under Section  4.1(c) or 4.1(d)  hereof,  but,  except as specified  above,  the
remainder of this Indenture and such Securities shall be unaffected thereby.

     Section 11.4 Conditions to Defeasance or Covenant Defeasance.

     The following shall be the conditions to application of either Section 11.2
or Section 11.3 hereof to the Outstanding Securities:

     (a)  The  Company  or  any  Subsidiary  Guarantor  shall  irrevocably  have
deposited  or  caused to be  deposited  with the  Trustee  (or  another  trustee
satisfying the requirements of Section 5.7 hereof who shall agree to comply with
the  provisions of this Article XI applicable to it) as trust funds in trust for
the purpose of making the following payments,  specifically  pledged as security
for, and dedicated solely to, the benefit of the Holders of such Securities, (A)
cash in United States dollars in an amount, or (B) U.S.  Government  Obligations
which through the scheduled payment of principal and interest in respect thereof
in accordance  with their terms will provide,  not later than one day before the
due date of any  payment,  money in an  amount,  or (C) a  combination  thereof,
sufficient, in the opinion of a nationally recognized firm of independent public
accountants  expressed  in a  written  certification  thereof  delivered  to the
Trustee,  to pay and  discharge,  and which  shall be applied by the Trustee (or
other qualifying  trustee) to pay and discharge,  the principal of (and premium,
if any, on) and interest on the  Outstanding  Securities on the Stated  Maturity
thereof (or  Redemption  Date, if  applicable),  provided that the Trustee shall
have been  irrevocably  instructed in writing by the Company to apply such money
or the  proceeds  of such U.S.  Government  Obligations  to said  payments  with
respect to the  Securities.  Before such a deposit,  the Company may give to the
Trustee,  in  accordance  with Section 10.1 hereof,  a notice of its election to
redeem all of the  Outstanding  Securities at a future date in  accordance  with
Article X hereof, which notice shall be irrevocable. Such irrevocable redemption
notice,  if given,  shall be given  effect in applying the  foregoing.  For this
purpose,  "U.S.  Government  Obligations"  means  securities that are (x) direct
obligations  of the United States of America for the timely payment of which its
full faith and credit is pledged or (y)  obligations  of a Person  controlled or
supervised by and acting as an agency or instrumentality of the United States of
America  the timely  payment of which is  unconditionally  guaranteed  as a full
faith and credit  obligation by the United States of America,  which,  in either
case,  are not callable or redeemable at the option of the issuer  thereof,  and
shall also include a depository  receipt issued by a bank (as defined in Section
3(a)(2) of the  Securities  Act),  as  custodian  with  respect to any such U.S.
Government  Obligation or a specific  payment of principal of or interest on any
such U.S.  Government  Obligation  held by such custodian for the account of the
holder of such  depository  receipt,  provided  that (except as required by law)
such  custodian is not  authorized to make any deduction from the amount payable
to the  holder  of such  depository  receipt  from any  amount  received  by the
custodian in respect of the U.S.  Government  Obligation or the specific payment
of principal of or interest on the U.S. Government  Obligation evidenced by such
depository receipt.

     (b) No Default or Event of Default  with  respect to the  Securities  shall
have  occurred  and be  continuing  on the date of such  deposit or,  insofar as
Sections  4.1(h) and 4.1(i) are concerned,  at any time during the period ending
on the 91st day after the date of such deposit.

     (c) Such  legal  defeasance  or  covenant  defeasance  shall  not cause the
Trustee  to have a  conflicting  interest  under  this  Indenture  or the  Trust
Indenture Act with respect to any  securities  of the Company or any  Subsidiary
Guarantor.

                                      E-203

<PAGE>



     (d) Such legal  defeasance  or  covenant  defeasance  shall not result in a
breach or  violation  of, or  constitute  a default  under,  any other  material
agreement or  instrument to which the Company or any  Subsidiary  Guarantor is a
party or by which it is bound,  as  evidenced  to the  Trustee  in an  Officers'
Certificate delivered to the Trustee concurrently with such deposit.

     (e) In the case of an election under Section 11.2 hereof, the Company shall
have delivered to the Trustee an Opinion of Counsel stating that (i) the Company
has received from, or there has been published by, the Internal  Revenue Service
a ruling,  or (ii) since the date of this  Indenture  there has been a change in
the  applicable  federal  income tax laws,  in either  case  providing  that the
Holders of the Outstanding  Securities will not recognize  income,  gain or loss
for federal income tax purposes as a result of such legal defeasance and will be
subject to federal income tax on the same amounts, in the same manner and at the
same times as would have been the case if such legal defeasance had not occurred
(it being understood that (x) such Opinion of Counsel shall also state that such
ruling or applicable  law is  consistent  with the  conclusions  reached in such
Opinion  of  Counsel  and (y) the  Trustee  shall  be  under  no  obligation  to
investigate the basis or correctness of such ruling).

     (f) In the case of an election under Section 11.3 hereof, the Company shall
have  delivered  to the  Trustee an  Opinion  of Counsel to the effect  that the
Holders of the Outstanding  Securities will not recognize  income,  gain or loss
for federal income tax purposes as a result of such covenant defeasance and will
be subject to federal income tax on the same amounts,  in the same manner and at
the same times as would have been the case if such covenant  defeasance  had not
occurred.

     (g)  The  Company  shall  have   delivered  to  the  Trustee  an  Officers'
Certificate and an Opinion of Counsel,  which,  taken  together,  state that all
conditions  precedent provided for relating to either the legal defeasance under
Section 11.2 hereof or the covenant  defeasance  under Section 11.3 (as the case
may be) have been complied with.

     Section  11.5  Deposited Money and U.S.  Government  Obligations to Be Held
                    in Trust; Other Miscellaneous Provisions.

     Subject to the provisions of the last paragraph of Section 9.3 hereof,  all
money and U.S. Government Obligations (including the proceeds thereof) deposited
with the Trustee (or other qualifying trustee--collectively for purposes of this
Section 11.5, the  "Trustee")  pursuant to Section 11.4 hereof in respect of the
Outstanding  Securities  shall be held in trust and applied by the  Trustee,  in
accordance  with the provisions of such  Securities and this  Indenture,  to the
payment,  either  directly or through any Paying  Agent  (including  the Company
acting as its own Paying Agent) as the Trustee may determine,  to the Holders of
such  Securities  of all  sums due and to  become  due  thereon  in  respect  of
principal  (and  premium,  if any)  and  interest,  but such  money  need not be
segregated from other funds except to the extent required by law.

     The Company shall pay and indemnify the Trustee against all taxes,  fees or
other charges imposed on or assessed against the U.S.  Governmental  Obligations
deposited pursuant to Section 11.4 hereof or the principal and interest received
in respect  thereof other than any such tax, fee or other charge which by law is
for the account of the Holders of the Outstanding Securities.

     Anything in this  Article XI to the contrary  notwithstanding,  the Trustee
shall  deliver or pay to the Company from time to time upon Company  Request any
money or U.S.  Government  Obligations  held by it as provided  in Section  11.4
hereof  which,  in the opinion of a nationally  recognized  firm of  independent
public accountants expressed in a written certification thereof delivered to the
Trustee,  are in excess of the amount thereof which would then be required to be
deposited to effect an equivalent  legal defeasance or covenant  defeasance,  as
applicable, in accordance with this Article.

     Section 11.6 Reinstatement.

     If the  Trustee  or any  Paying  Agent  is  unable  to apply  any  money in
accordance  with  Section  11.5 hereof by reason of any order or judgment of any
court or governmental authority enjoining,  restraining or otherwise prohibiting
such application,  then the Company's and the Subsidiary Guarantors' obligations
under this  Indenture  and the  Securities  shall be revived and  reinstated  as
though no deposit had occurred  pursuant to Section 11.2 or 11.3 hereof,  as the
case may be,  until such time as the  Trustee or Paying  Agent is  permitted  to
apply all such money in accordance with Section 11.5 hereof; provided,  however,
that if the Company or any Subsidiary  Guarantor  makes any payment of principal
of  (or  premium,  if  any,  on)  or  interest  on any  Security  following  the
reinstatement of its obligations, the Company or such Subsidiary Guarantor shall
be  subrogated  to the rights of the Holders of such  Securities to receive such
payment from the money held by the Trustee or Paying Agent.

                                  ARTICLE XII.

                              SUBSIDIARY GUARANTEES

     Section 12.1 Unconditional Guarantee.

     Each Subsidiary  Guarantor hereby  unconditionally,  jointly and severally,
guarantees  (each such guarantee  being  referred to herein as this  "Subsidiary
Guarantee," with all such guarantees being referred to herein as the "Subsidiary
Guarantees")  to each Holder of  Securities  authenticated  and delivered by the
Trustee and to the Trustee and its successors  and assigns,  the full and prompt
performance of the Company's obligations under this Indenture and the Securities
and that:

     (a)  the  principal  of (and  premium,  if any,  on)  and  interest  on the
Securities  will be  promptly  paid in full when due,  whether at  maturity,  by
acceleration,  redemption or otherwise, and interest on the overdue principal of
and  interest on the  Securities,  if any, to the extent  lawful,  and all other
obligations of the Company to the Holders or the Trustee hereunder or thereunder
will be promptly  paid in full or performed,  all in  accordance  with the terms
hereof and thereof; and

     (b) in  case  of any  extension  of  time  of  payment  or  renewal  of any
Securities or of any such other  obligations,  the same will be promptly paid in
full when due or  performed  in  accordance  with the terms of the  extension or
renewal,  whether at Stated  Maturity,  by acceleration  or otherwise;  subject,
however,  in the case of clauses (a) and (b) above, to the limitations set forth
in Section 12.4 hereof.

     Failing  payment when due of any amount so guaranteed or any performance so
guaranteed for whatever  reason,  the Subsidiary  Guarantors will be jointly and
severally  obligated  to pay the same  immediately.  Each  Subsidiary  Guarantor
hereby agrees that its obligations  hereunder  shall, to the extent permitted by
law,  be   unconditional,   irrespective   of  the   validity,   regularity   or
enforceability of the Securities or this Indenture, the absence of any action to
enforce  the same,  any waiver or consent by any Holder of the  Securities  with
respect to any  provisions  hereof or  thereof,  the  recovery  of any  judgment
against the  Company,  any action to enforce the same or any other  circumstance
which might otherwise  constitute a legal or equitable discharge or defense of a
guarantor.  Each Subsidiary  Guarantor hereby waives, to the extent permitted by
law, diligence, presentment, demand of payment, filing of claims with a court in
the event of insolvency  or  bankruptcy  of the Company,  any right to require a
proceeding first against the Company, protest, notice and all demands whatsoever
and covenants  that its Subsidiary  Guarantee  will not be discharged  except by
complete  performance  of the  obligations  contained  in the  Securities,  this
Indenture  and in this  Subsidiary  Guarantee.  If any Holder or the  Trustee is
required by any court or  otherwise  to return to the  Company,  any  Subsidiary
Guarantor,  or any  custodian,  trustee,  liquidator or other  similar  official
acting in relation to the Company or any Subsidiary  Guarantor,  any amount paid
by the Company or any Subsidiary  Guarantor to the Trustee or such Holder,  this
Subsidiary Guarantee, to the extent theretofore discharged,  shall be reinstated
in full  force and  effect.  Each  Subsidiary  Guarantor  agrees it shall not be
entitled  to enforce  any right of  subrogation  in  relation  to the Holders in


                                      E-205

<PAGE>


respect  of any  obligations  guaranteed  hereby  until  payment  in full of all
obligations guaranteed hereby. Each Subsidiary Guarantor further agrees that, as
between  each  Subsidiary  Guarantor,  on the one hand,  and the Holders and the
Trustee,  on the other  hand,  (x) the  maturity of the  obligations  guaranteed
hereby may be  accelerated  as provided in Article IV hereof for the purposes of
this  Subsidiary  Guarantee,  notwithstanding  any  stay,  injunction  or  other
prohibition   preventing  such   acceleration  in  respect  of  the  obligations
guaranteed  hereby, and (y) in the event of any acceleration of such obligations
as  provided  in Article IV hereof,  such  obligations  (whether  or not due and
payable) shall forthwith become due and payable by each Subsidiary Guarantor for
the purpose of this Subsidiary Guarantee.

     Section 12.2 Subsidiary Guarantors May Consolidate, etc., on Certain Terms.

     (a) Except as set forth in Article VII hereof,  nothing  contained  in this
Indenture or in any of the Securities shall prevent any  consolidation or merger
of a  Subsidiary  Guarantor  with or into  the  Company  or  another  Subsidiary
Guarantor or shall prevent any sale,  conveyance or other  disposition of all or
substantially  all the  Properties  of a Subsidiary  Guarantor to the Company or
another Subsidiary Guarantor.

     (b) Except as set forth in Article VII hereof,  nothing  contained  in this
Indenture or in any of the Securities shall prevent any  consolidation or merger
of a  Subsidiary  Guarantor  with or into a Person  other  than the  Company  or
another  Subsidiary  Guarantor  (whether or not  Affiliated  with the Subsidiary
Guarantor),  or  successive  consolidations  or  mergers  in which a  Subsidiary
Guarantor or its successor or successors  shall be a party or parties,  or shall
prevent any sale,  conveyance or other  disposition of all or substantially  all
the  Properties of a Subsidiary  Guarantor to a Person other than the Company or
another  Subsidiary  Guarantor  (whether or not  Affiliated  with the Subsidiary
Guarantor)  authorized to acquire and operate the same; provided,  however, that
(i) immediately after such transaction, and giving effect thereto, no Default or
Event of Default  shall have  occurred  as a result of such  transaction  and be
continuing,  (ii) such  transaction  shall not violate any of the  covenants  of
Sections 9.1 through 9.19 hereof,  and (iii) each  Subsidiary  Guarantor  hereby
covenants and agrees that, upon any such consolidation, merger, sale, conveyance
or other disposition, such Subsidiary Guarantor's Subsidiary Guarantee set forth
in this Article XII, and the due and punctual  performance and observance of all
of the  covenants  and  conditions  of this  Indenture  to be  performed by such
Subsidiary  Guarantor,  shall  be  expressly  assumed  (in the  event  that  the
Subsidiary  Guarantor  is  not  the  surviving  corporation  in  a  merger),  by
supplemental  indenture  satisfactory  in  form  to the  Trustee,  executed  and
delivered to the Trustee, by such Person formed by such  consolidation,  or into
which the Subsidiary  Guarantor  shall have merged,  or by the Person that shall
have  acquired such  Property  (except to the extent the following  Section 12.3
would  result in the release of such  Subsidiary  Guarantee,  in which case such
surviving  Person or transferee  of such Property  shall not have to execute any
such  supplemental  indenture  and  shall  not have to  assume  such  Subsidiary
Guarantor's  Subsidiary  Guarantee).  In the  case  of any  such  consolidation,
merger,  sale,  conveyance or other  disposition  and upon the assumption by the
successor  Person,  by  supplemental  indenture  executed  and  delivered to the
Trustee  and  satisfactory  in form  to the  Trustee  of the  due  and  punctual
performance  of all of the  covenants  and  conditions  of this  Indenture to be
performed by the Subsidiary  Guarantor,  such successor  Person shall succeed to
and be substituted  for the  Subsidiary  Guarantor with the same effect as if it
had been named herein as the initial Subsidiary Guarantor.

     Section 12.3 Release of Subsidiary Guarantors.

     Upon the sale or  disposition  (by  merger or  otherwise)  of a  Subsidiary
Guarantor (or all or substantially all of its Properties) to a Person other than
the Company or another  Subsidiary  Guarantor and pursuant to a transaction that
is otherwise in compliance with the terms of this  Indenture,  including but not
limited to the  provisions  of Section  12.2  hereof or  pursuant to Article VII
hereof,  such Subsidiary  Guarantor shall be deemed released from its Subsidiary
Guarantee and all related obligations under this Indenture;  provided,  however,
that any such  release  shall occur only to the extent that all  obligations  of
such  Subsidiary  Guarantor under all of its guarantees of, and under all of its
pledges of assets or other security  interests which secure,  other Indebtedness
of the Company or any other Restricted  Subsidiary  shall also  be released upon

                                      E-206

<PAGE>



such  sale or other  disposition.  The  Trustee  shall  deliver  an  appropriate
instrument evidencing such release upon receipt of a Company Request accompanied
by an Officers'  Certificate and an Opinion of Counsel certifying that such sale
or other  disposition  was made by the Company in accordance with the provisions
of  this  Indenture.   Each  Subsidiary  Guarantor  that  is  designated  as  an
Unrestricted  Subsidiary in  accordance  with the  provisions of this  Indenture
shall be released  from its  Subsidiary  Guarantee  and all related  obligations
under this Indenture for so long as it remains an Unrestricted  Subsidiary.  The
Trustee shall deliver an appropriate instrument evidencing such release upon its
receipt of the Board Resolution  designating such Unrestricted  Subsidiary.  Any
Subsidiary  Guarantor  not released in  accordance  with this Section 12.3 shall
remain liable for the full amount of principal of (and premium,  if any, on) and
interest on the Securities as provided in this Article XII.

     Section 12.4 Limitation of Subsidiary Guarantors' Liability.

     Each Subsidiary Guarantor, and by its acceptance hereof each Holder, hereby
confirm that it is the  intention of all such parties that the guarantee by such
Subsidiary  Guarantor  pursuant to its  Subsidiary  Guarantee  not  constitute a
fraudulent  transfer or conveyance for purposes of the Federal  Bankruptcy Code,
the Uniform Fraudulent  Conveyance Act, the Uniform  Fraudulent  Transfer Act or
any similar  federal or state law. To effectuate  the foregoing  intention,  the
Holders  and  each  Subsidiary  Guarantor  hereby  irrevocably  agree  that  the
obligations of such Subsidiary Guarantor under its Subsidiary Guarantee shall be
limited  to the  maximum  amount  as will,  after  giving  effect  to all  other
contingent and fixed  liabilities of such Subsidiary  Guarantor and after giving
effect to any  collections  from or  payments  made by or on behalf of any other
Subsidiary  Guarantor  in respect of the  obligations  of such other  Subsidiary
Guarantor  under its  Subsidiary  Guarantee  or pursuant to Section 12.5 hereof,
result in the  obligations  of such  Subsidiary  Guarantor  under its Subsidiary
Guarantee not constituting such a fraudulent  conveyance or fraudulent transfer.
This  Section  12.4 is for  the  benefit  of the  creditors  of each  Subsidiary
Guarantor.

     Section 12.5 Contribution.

     In  order  to  provide  for  just  and  equitable  contribution  among  the
Subsidiary  Guarantors,  the Subsidiary  Guarantors agree, inter se, that in the
event  any  payment  or  distribution  is made by any  Subsidiary  Guarantor  (a
"Funding  Guarantor")  under its Subsidiary  Guarantee,  such Funding  Guarantor
shall be entitled to a  contribution  from each other  Subsidiary  Guarantor (if
any) in a pro rata amount based on the  Adjusted  Net Assets of each  Subsidiary
Guarantor  (including  the  Funding  Guarantor)  for all  payments,  damages and
expenses  incurred  by that  Funding  Guarantor  in  discharging  the  Company's
obligations with respect to the Securities or any other  Subsidiary  Guarantor's
obligations with respect to its Subsidiary Guarantee.

     Section 12.6 Severability.

     In case any  provision  of this  Subsidiary  Guarantee  shall  be  invalid,
illegal or  unenforceable,  that portion of such  provision that is not invalid,
illegal or unenforceable shall remain in effect, and the validity, legality, and
enforceability  of the remaining  provisions shall not in any way be affected or
impaired thereby.

                                  ARTICLE XIII.

                                  MISCELLANEOUS

     Section 13.1 Compliance Certificates and Opinions.

     Upon any application or request by the Company or any Subsidiary  Guarantor
to the Trustee to take any action  under any  provision of this  Indenture,  the
Company or such Subsidiary  Guarantor,  as the case may be, shall furnish to the
Trustee  such  certificates  and  opinions  as may be  required  under the Trust


                                      E-207

<PAGE>


Indenture  Act or this  Indenture.  Each such  certificate  and each such  legal
opinion  shall be in the  form of an  Officers'  Certificate  or an  Opinion  of
Counsel,  as  applicable,  and  shall  comply  with  the  requirements  of  this
Indenture.

     Every certificate or opinion with respect to compliance with a condition or
covenant provided for in this Indenture shall include:

          (1) a statement that each Person  signing such  certificate or opinion
     has read such covenant or condition  and the  definitions  herein  relating
     thereto;

          (2) a brief statement as to the nature and scope of the examination or
     investigation  upon which the  statements  or  opinions  contained  in such
     certificate or opinion are based;

          (3) a statement that, in the opinion of each such Person,  such Person
     has made such examination or investigation as is necessary to enable him to
     express an informed opinion as to whether or not such covenant or condition
     has been complied with; and

          (4) a  statement  as to whether,  in the opinion of each such  Person,
     such condition or covenant has been complied with.

     The  certificates and opinions  provided  pursuant to this Section 13.1 and
the  statements  required  by this  Section  13.1 shall be  satisfactory  to the
Trustee and comply in all respects with TIA Sections 314(c) and (e).

     Section 13.2 Form of Documents Delivered to Trustee.

     In any case where  several  matters  are  required to be  certified  by, or
covered by an opinion of, any specified  Person,  it is not  necessary  that all
such  matters  be  certified  by, or covered by the  opinion  of,  only one such
Person,  or that they be so certified or covered by only one  document,  but one
such Person may certify or give an opinion  with respect to some matters and one
or more other such Persons as to other matters,  and any such Person may certify
or give an opinion as to such matters in one or several documents.

     Any  certificate  or  opinion  of an  officer  may be based,  insofar as it
relates to legal matters,  upon a certificate or opinion of, or  representations
by,  counsel,  unless such officer knows,  or in the exercise of reasonable care
should know, that the certificate or opinion or representations  with respect to
the matters upon which his  certificate or opinion is based are  erroneous.  Any
such Opinion of Counsel may be based,  insofar as it relates to factual matters,
upon an officers' certificate,  unless such counsel knows, or in the exercise of
reasonable care should know,  that the certificate  with respect to such matters
is erroneous.

     Where  any  Person  is  required  to  make,  give  or  execute  two or more
applications,  requests, consents,  certificates,  statements, opinions or other
instruments  under this Indenture,  they may, but need not, be consolidated  and
form one instrument.

     Section 13.3 Acts of Holders.

     (a) Any request, demand, authorization,  direction, notice, consent, waiver
or other action  provided by this  Indenture to be given or taken by Holders may
be embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such  Holders in person or by agents duly  appointed in writing;
and, except as herein  otherwise  expressly  provided,  such action shall become
effective when such  instrument or instruments are delivered to the Trustee and,
where it is hereby  expressly  required,  to the  Company.  Such  instrument  or
instruments (and the action embodied  therein and evidenced  thereby) are herein
sometimes  referred to as the "Act" of the Holders  signing such  instrument  or
instruments.  Proof  of  execution  of  any  such  instrument  or  of a  writing


                                      E-208

<PAGE>


appointing  any such agent shall be sufficient for any purpose of this Indenture
and  conclusive  in favor of the Trustee and the Company,  if made in the manner
provided in this Section.

     (b) The fact and date of the execution by any Person of any such instrument
or writing may be proved by the affidavit of a witness of such execution or by a
certificate  of a notary  public  or  other  officer  authorized  by law to take
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him the execution thereof. Where such execution is by
a  signer  acting  in a  capacity  other  than  his  individual  capacity,  such
certificate or affidavit  shall also constitute  sufficient  proof of authority.
The fact and date of the  execution of any such  instrument  or writing,  or the
authority  of the  Person  executing  the same,  may also be proved in any other
manner which the Trustee deems sufficient.

     (c) The ownership,  principal  amount and serial numbers of Securities held
by any Person, and the date of holding the same, shall be proved by the Security
Register.

     (d) If the  Company  shall  solicit  from the  Holders  of  Securities  any
request, demand, authorization, direction, notice, consent, waiver or other Act,
the Company  may, at its option,  by or pursuant to a Board  Resolution,  fix in
advance a record  date for the  determination  of Holders  entitled to give such
request, demand, authorization, direction, notice, consent, waiver or other Act,
but the Company shall have no obligation to do so.  Notwithstanding  TIA Section
316(c),  such record date shall be the record date  specified  in or pursuant to
such Board  Resolution,  which shall be a date not earlier than the date 30 days
prior to the first solicitation of Holders generally in connection therewith and
not later than the date such solicitation is completed. If such a record date is
fixed, such request, demand,  authorization,  direction, notice, consent, waiver
or other Act may be given before or after such record date, but only the Holders
of record at the close of  business  on such  record  date shall be deemed to be
Holders  for the  purposes  of  determining  whether  Holders  of the  requisite
proportion of Outstanding  Securities  have authorized or agreed or consented to
such request, demand, authorization, direction, notice, consent, waiver or other
Act, and for that  purpose the  Outstanding  Securities  shall be computed as of
such record date, provided that no such  authorization,  agreement or consent by
the Holders on such record date shall be deemed effective unless it shall become
effective  pursuant to the  provisions  of this  Indenture not later than eleven
months after the record date.

     (e) Any request, demand, authorization,  direction, notice, consent, waiver
or other Act of the Holder of any Security shall bind every future Holder of the
same Security and the Holder of every Security  issued upon the  registration of
transfer  thereof  or in  exchange  therefor  or in lieu  thereof  in respect of
anything  done,  omitted or suffered to be done by the Trustee or the Company in
reliance  thereon,  whether  or not  notation  of such  action is made upon such
Security.

     Section 13.4 Notices, etc. to Trustee, Company and Subsidiary Guarantors.

     Any request, demand,  authorization,  direction, notice, consent, waiver or
Act of Holders or other  document  provided or permitted by this Indenture to be
made upon, given or furnished to or filed with,

          (1) the Trustee by any Holder, the Company,  any Subsidiary  Guarantor
     or any holder of Senior  Indebtedness shall be sufficient for every purpose
     hereunder  if made,  given,  furnished  or filed in writing (in the English
     language) and delivered in person or mailed by certified or registered mail
     (return receipt requested) to the Trustee at its Corporate Trust Office; or

          (2) the Company or any  Subsidiary  Guarantor by the Trustee or by any
     Holder shall be sufficient for every purpose  hereunder  (unless  otherwise
     herein  expressly  provided)  if in writing (in the English  language)  and
     delivered  in person or mailed by  certified  or  registered  mail  (return
     receipt  requested)  to  the  Company  or  such  Subsidiary  Guarantor,  as
     applicable,  addressed to it at the Company's  offices  located at 5005 LBJ


                                      E-209

<PAGE>



     Freeway,  Suite 1000,  Dallas,  Texas  75244,  Attention:  Chief  Financial
     Officer,  or at any other  address  otherwise  furnished  in writing to the
     Trustee by the Company.

     Section 13.5 Notice to Holders; Waiver.

     Where  this  Indenture  provides  for notice of any event to Holders by the
Company  or the  Trustee,  such  notice  shall  be  sufficiently  given  (unless
otherwise herein expressly provided) if in writing (in the English language) and
mailed,  first-class  postage prepaid, to each Holder affected by such event, at
his address as it appears in the  Security  Register,  not later than the latest
date, and not earlier than the earliest date,  prescribed for the giving of such
notice.  In any case  where  notice to  Holders  is given by mail,  neither  the
failure to mail such  notice,  nor any  defect in any  notice so mailed,  to any
particular  Holder shall affect the  sufficiency  of such notice with respect to
other  Holders.  Any notice mailed to a Holder in the manner  herein  prescribed
shall be  conclusively  deemed to have been received by such Holder,  whether or
not such Holder actually receives such notice. Where this Indenture provides for
notice  in any  manner,  such  notice  may be waived in  writing  by the  Person
entitled to receive  such  notice,  either  before or after the event,  and such
waiver  shall be the  equivalent  of such  notice.  Waivers of notice by Holders
shall be filed  with the  Trustee,  but such  filing  shall  not be a  condition
precedent to the validity of any action taken in reliance upon such waiver.

     In case by reason of the  suspension of or  irregularities  in regular mail
service  or by reason  of any other  cause,  it shall be  impracticable  to mail
notice of any event to Holders when such notice is required to be given pursuant
to any  provision  of this  Indenture,  then any manner of giving such notice as
shall be satisfactory  to the Trustee shall be deemed to be a sufficient  giving
of such notice for every purpose hereunder.

     Section 13.6 Effect of Headings and Table of Contents.

     The Article and Section  headings  herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.

     Section 13.7 Successors and Assigns.

     All  covenants  and  agreements  in this  Indenture  by the Company and the
Subsidiary  Guarantors  shall  bind their  respective  successors  and  assigns,
whether so  expressed or not. All  agreements  of the Trustee in this  Indenture
shall bind its successor.

     Section 13.8 Severability.

     In  case  any  provision  in this  Indenture  or in the  Securities  or the
Subsidiary Guarantees shall be invalid, illegal or unenforceable,  the validity,
legality and enforceability of the remaining  provisions shall not in any way be
affected or impaired thereby,  and a Holder shall have no claim therefor against
any party hereto.

     Section 13.9 Benefits of Indenture.

     Nothing in this Indenture or in the Securities,  express or implied,  shall
give to any  Person  (other  than the  parties  hereto,  any Paying  Agent,  any
Registrar  and their  successors  hereunder,  the Holders and, to the extent set
forth in Section 12.4 hereof, creditors of Subsidiary Guarantors and the holders
of Senior  Indebtedness) any benefit or any legal or equitable right,  remedy or
claim under this Indenture.

     Section 13.10 Governing Law; Trust Indenture Act Controls.

     (a) THIS INDENTURE,  THE SUBSIDIARY  GUARANTEES AND THE SECURITIES SHALL BE
GOVERNED BY, AND  CONSTRUED  AND ENFORCED IN  ACCORDANCE  WITH,  THE LAWS OF THE
STATE OF NEW  YORK  BUT  WITHOUT  GIVING  EFFECT  TO  APPLICABLE  PRINCIPLES  OF
CONFLICTS  OF LAW TO THE  EXTENT  THAT THE  APPLICATION  OF THE LAWS OF  ANOTHER
JURISDICTION  WOULD  BE  REQUIRED  THEREBY.  THE  COMPANY  AND  EACH  SUBSIDIARY
GUARANTOR  IRREVOCABLY  SUBMIT TO THE  NON-EXCLUSIVE  JURISDICTION OF ANY UNITED
STATES FEDERAL OR NEW YORK STATE COURT SITTING IN THE BOROUGH OF MANHATTAN,  THE
CITY OF NEW YORK IN ANY ACTION OR PROCEEDING  ARISING OUT OF OR RELATING TO THIS
INDENTURE, THE SECURITIES OR THE SUBSIDIARY GUARANTEES, AND THE COMPANY AND EACH
SUBSIDIARY GUARANTOR IRREVOCABLY AGREE THAT ALL CLAIMS IN RESPECT OF SUCH ACTION
OR PROCEEDING MAY BE HEARD AND DETERMINED BY ANY SUCH COURT.

     (b) This Indenture is subject to the provisions of the Trust  Indenture Act
that  are  required  to be part of  this  Indenture  and  shall,  to the  extent
applicable,  be  governed  by such  provisions.  If and to the  extent  that any
provision of this  Indenture  limits,  qualifies  or  conflicts  with the duties
imposed by operation of Section 318(c) of the Trust  Indenture Act, or conflicts
with any provision  (an  "incorporated  provision")  required by or deemed to be
included in this  Indenture by operation  of such Trust  Indenture  Act section,
such imposed duties or incorporated provision shall control.

     Section 13.11 Legal Holidays.

     In any case where any Interest  Payment  Date,  Redemption  Date, or Stated
Maturity  or  Maturity  of any  Security  shall  not  be a  Business  Day,  then
(notwithstanding  any other  provision of this Indenture or of the Securities or
the Subsidiary Guarantee) payment of interest or principal (and premium, if any)
need not be made on such date, but may be made on the next  succeeding  Business
Day with the same  force and  effect as if made on the  Interest  Payment  Date,
Redemption Date or at the Stated Maturity or Maturity;  provided,  however, that
no interest  shall  accrue for the period from and after such  Interest  Payment
Date, Redemption Date, Stated Maturity or Maturity, as the case may be.

     Section 13.12 No Recourse Against Others.

     A director, officer, employee,  stockholder,  incorporator or Affiliate, as
such, past, present or future, of the Company or any Subsidiary  Guarantor shall
not have any personal liability under the Securities or this Indenture by reason
of his or its status as a director, officer, employee, stockholder, incorporator
or  Affiliate  or any  liability  for  any  obligations  of the  Company  or any
Subsidiary  Guarantor  under the  Securities or this  Indenture or for any claim
based on, in respect of or by reason of such obligations or their creation. Each
Holder,  by  accepting  any of the  Securities,  waives  and  releases  all such
liability to the extent permitted by applicable law.

     Section 13.13 Duplicate Originals.

     The  parties  may  sign  any  number  of  copies  or  counterparts  of this
Indenture.  Each  signed  copy shall be an  original,  but all of them  together
represent the same agreement.

     Section 13.14 No Adverse Interpretation of Other Agreements.

     This Indenture may not be used to interpret another indenture, loan or debt
agreement of the Company or any of its Subsidiaries. Any such indenture, loan or
debt agreement may not be used to interpret this Indenture.
