the offices of the Company as set forth on the signature page of this Agreement,
together  with payment of the aggregate Warrant Exercise Price for the number of
Warrant  Shares  in respect of which such Warrants are being exercised in lawful
money  of the United States of America.  The Warrants may also be exercised in a
"cashless"  or "net-issue" exercise by delivery to the offices of the Company of
(A)  a  written  notice  of  election to exercise Warrants, duly executed by the
Warrant  Holder  in  the  form set forth on the reverse of, or attached to, such

be  deemed to have become holder of record of such Warrant Shares as of the date
of  exercise  of  such  Warrants;  provided,  that,  no  Warrant  Holder will be
permitted  to  designate  that such Warrant Shares be issued to any Person other
than  such Warrant Holder unless each condition to transfer contained in Article
V  hereof  which would be applicable to a transfer of Warrants or Warrant Shares
has  been  satisfied."

stock  (whether  shares  of  such  Common Stock or of capital stock of any other

combine the outstanding Common Stock into a smaller number of shares, the number
of Warrant Shares purchasable upon an exercise of each Warrant after the time of
the  record  date  for  such  dividend  or  of the effective date of such split,
subdivision  or  combination  shall be adjusted to equal the number of shares of
Common  Stock  and  other  securities  which  a Holder having the same number of
shares  of  Common  Stock, and other securities, as the number of Warrant Shares
into  which each Warrant is exercisable immediately prior to such record date or

payable  upon  exercise  of the  Warrant  shall  simultaneously  be  adjusted by
multiplying  such  Warrant  Price  immediately  prior  to such  adjustment  by a
fraction,  the  numerator  of which  shall be the number of Warrant  Shares into
which such Warrant was exercisable immediately prior to such adjustment, and the
denominator  of which  shall be the  number of  Warrant  Shares  into which such
Warrant was exercisable immediately thereafter."

to 3TEC from each party  receiving  securities  of 3TEC  pursuant to the Merger;
notwithstanding  the  foregoing,  although  all  parties  hereto  will  take all
reasonable efforts to obtain such letters, the receipt of such letter from those
parties receiving only Warrants will not be a condition to Closing;

attached hereto."

("Damages")  which  may be incurred by any 3TEC Indemnified Party relating to or
arising  out  any  breach  by Prepayout Members of any of their representations,

Interests"  as  described in Section 9.6(c) of the Magellan Operating Agreement)
or  (y)  commences  an  action  or  proceeding  of the type described in Section
6.1(k),  and  as a result any party hereto terminates this Agreement pursuant to
Section  11.1  due  to the failure of a condition precedent described in Section

exercises  a  preferential  right  to  purchase  under Article XV.J of the Joint
Operating  Agreement dated March 23, 1994 relating to leases at Breton Sound and
then  3TEC  terminates  this  Agreement  pursuant  to  Section 11.1 as a result.
Subject  to the terms of this Section 12.4, the Prepayout Members severally (and
expressly  not  joint and severally) agree to reimburse 3TEC for one-half of its

Section  11.1  due  to the failure of the condition described in Section 6.2(h).
For  purposes  of  this  Section,  "Transaction  Costs"  mean all documented and
reasonable  out-of-pocket  expenses  and  disbursements  incurred  by  3TEC  in

severally  (and expressly not jointly and severally) agree to indemnify and hold
harmless the 3TEC Indemnified Parties and, after the Closing, Magellan, from and
against  any and all Damages which may be incurred by any 3TEC Indemnified Party
or  Magellan relating to or arising out of any actions or proceedings brought by

value  of  the  Lafourche  Basin  Levee  District's and the West Jefferson Levee
District's  leases  in  the  Bay  de  Chene Field as a result of the judgment or
settlement  of  Lafourche Basin Levee District and West Jefferson Levee District

v.  Texaco,  Inc., et al. Docket No. 76337, Seventeenth Judicial District Court,

prospects  as identified on Exhibit J attached hereto and any amounts which 3TEC
or  Magellan  may hereafter invest in such prospects or any future value created
by  3TEC's or Magellan's drilling and other operating activities associated with
such  leases.  Notwithstanding  any  other  provisions  of  this  Agreement, the
indemnification  obligations  under this Section 12.4(d) shall survive until the
above-referenced  lawsuit  has  been  dismissed  with  prejudice  or  a  final
non-appealable  judgment has been entered which does not include cancellation or
diminution  of  value  of  such  leases.

     (e)     The liability of Prepayout Members under this Section 12.4 shall be
several  (and expressly not joint and several), except in the instance of a 3TEC
Claim relating to or out of any breach by a Prepayout Member of a representation
and  warranty  in  Section  7.2,  Section  7.3  or  Section  7.19  that  applies
                   ------------   ------------      -------------
specifically to such Prepayout Member (in which event such Prepayout Member, and
no  other  Prepayout  Member,  shall  have  liability).  With  respect  to  any
indemnification  obligation  under this Section 12.4 for which Prepayout Members
have  several  liability, the several share of each Prepayout Member shall be as
set  forth  in  Exhibit A and in no event shall such Prepayout Member's share of
any  such  indemnification  obligation  exceed  such  several  share.

     (f)     Notwithstanding  the  foregoing  or  anything  else  herein  to the
contrary,  the  indemnification  obligation of the Prepayout Members pursuant to
subparagraphs (a) through (e) above of this Section 12.4 shall be subject to the
following:



     (i) No  indemnification  shall be required to be made by Prepayout  Members
     pursuant to this Section  12.4 with respect to any 3TEC Claims  arising out
     or resulting  from the breach of the  representations  and  warranties  set
     forth in Article VII (exclusive of the representations set forth in Section
     7.18)),  except to the  extent  that the  aggregate  amount of the  Damages
     incurred  by the 3TEC  Indemnified  Parties  with  respect to all such 3TEC
     Claims exceeds $100,000.

     (ii) No  indemnification  shall be required to be made by Prepayout Members
     pursuant to this Section  12.4 with respect to any 3TEC Claims  arising out
     or resulting  from the breach of the  representations  and  warranties  set
     forth in Section 7.18,  except to the extent that the  aggregate  amount of
     the Damages  incurred by the 3TEC  Indemnified  Parties with respect to all
     such 3TEC Claims exceeds $100,000.

     (iii) No Prepayout  Member  shall be obligated to pay the 3TEC  Indemnified
     Parties pursuant to this Section 12.4 (excluding for this purpose,  Section
     12.4(c)) an  aggregate  amount in excess of (x) the amount  stipulated  for
     such Prepayout Member in Exhibit A minus (y) all amounts previously paid by
     such Prepayout Member pursuant to Section 12.4(c).  The deduction described
     in the  preceding  sentence  relating to amounts  paid  pursuant to Section
     12.4(c)  shall not be  construed to require any 3TEC  Indemnified  Party to
     return any amounts previously  received by it pursuant to this Section 12.4
     from  the  Prepayout  Members  or to put  any cap on the  liability  of the
     Prepayout Members under Section 12.4(c).



     (iv) A Prepayout Member shall have the right to satisfy any indemnification
     obligation  under this Section 12.4 (other than  obligations  under Section
     12.4(b)) by delivering,  at its election,  Common Stock Shares or Preferred
     Stock Shares, as provided in this subsection (f)(iv). If a Prepayout Member
     so  exercises  its right,  the number of Common  Stock  Shares or Preferred
     Stock Shares so delivered shall be equal to the amount (or portion thereof)
     of the  obligation so owed to be paid with Common Stock Shares or Preferred
     Stock Shares (as  applicable)  divided by (A) in the instance of the Common
     Stock Shares,  the Current  Market Price (as defined  below) and (B) in the
     instance of the Preferred  Stock Shares,  the greater of (x) $18.00 and (y)
     the aggregate Current Market Price of the shares of Common Stock into which
     such Preferred Stock Shares are then  convertible  divided by the number of
     Preferred Stock Shares to be delivered.  As used herein,  the term "Current
     Market Price" shall mean the average of the last reported  sales prices for
     the Common Stock for the 10  consecutive  Trading Days ending on the second
     Trading  Day  prior to  delivery  in  satisfaction  of the  indemnification
     obligation.  The last  reported  sales price for each day shall be the last
     reported sales price of the Common Stock on such date on the exchange where
     it is  primarily  traded,  or,  if the  Common  Stock is not  traded  on an
     exchange, the Common Stock shall be valued at the last reported sales price
     on such date on the NASDAQ National Market System,  or, if the Common Stock
     is not traded on the NASDAQ National Market System or any similar system of
     automated  dissemination  of quotations of  securities  prices,  the Common
     Stock  shall be valued at the  closing bid price (or average of bid prices)
     last quoted on such date as reported on an  established  quotation  service
     for  over-the-counter  securities.  As used in this subsection (f)(iv), the
     term  "Trading  Days"  shall  mean (1) if the  Common  Stock is  listed  or
     admitted for trading on any generally  recognized U.S. securities exchange,
     days on which such securities  exchange is open for business and (2) if the
     Common Stock is quoted on the NASDAQ  National Market System or any similar
     system of automated  dissemination of quotations of securities prices, days
     on which trades may be made on such system.

     (g)     Subject to the terms of this Section 12.4, 3TEC agrees to indemnify
and  hold  harmless,  each  Prepayout  Member  and  their  respective  partners,
shareholders,  members,  directors,  officers,  managers,  employees,  agents,
successors  and  assigns  (collectively,  the  "Prepayout  Member  Indemnified
Parties")  from  and  against  any  and all Damages which may be incurred by any
Prepayout Member Indemnified Party relating to or arising out any breach by 3TEC
of  any of its representations, warranties, covenants or agreements contained in
this  Agreement  or the other Transaction Documents ("Prepayout Member Claims").

     (h)     Promptly  after  receipt  by  an  indemnified  party  under Section
12.4(a), Section 12.4(c) or 12.4(d) of notice of the commencement of any action,
such  indemnified  party  shall,  if  a  claim  in respect thereof is to be made
against  an  indemnifying  party  under such Section, give written notice to the
indemnifying party of the commencement thereof, but the failure so to notify the
indemnifying party shall not relieve it of any liability that it may have to any
indemnified  party except to the extent the indemnifying party demonstrates that
the defense of such action is prejudiced thereby.  In case any such action shall
be  brought against an indemnified party and it shall give written notice to the
indemnifying  party of the commencement thereof, the indemnifying party shall be
entitled  to  participate therein and, to the extent that it may wish, to assume
the  defense  thereof  with  counsel reasonably satisfactory to such indemnified
party.  If  the  indemnifying party elects to assume the defense of such action,
the indemnified party shall have the right to employ separate counsel at its own
expense  and  to  participate in the defense thereof.  If the indemnifying party
elects  not  to  assume  (or  fails  to  assume) the defense of such action, the
indemnified  party  shall  be entitled to assume the defense of such action with
counsel  of  its  own  choice, at the expense of the indemnifying party.  If the
action is asserted against both the indemnifying party and the indemnified party
and there is a conflict of interests which renders it inappropriate for the same
counsel  to represent both the indemnifying party and the indemnified party, the
indemnifying  party shall be responsible for paying for separate counsel for the
indemnified party; provided, however, that if there is more than one indemnified
party,  the indemnifying party shall not be responsible for paying for more than
one  separate firm of attorneys to represent the indemnified parties, regardless
of  the  number  of  indemnified  parties.  If  the indemnifying party elects to
assume  the  defense of such action, (i) no compromise or settlement thereof may
be  effected  by  the indemnifying party without the indemnified party's written
consent  (which  shall  not  be  unreasonably  withheld)  unless the sole relief
provided is monetary damages that are paid in full by the indemnifying party and
(ii)  the  indemnifying  party  shall  have  no  liability  with  respect to any
compromise  or  settlement  thereof  effected without its written consent (which
shall  not  be  unreasonably  withheld).



     (i)     THE  PARTIES  RECOGNIZE  THAT  AN  INDEMNITEE  MAY  BE  ENTITLED TO
INDEMNIFICATION  HEREUNDER  FROM  ACTS  OR OMISSIONS THAT ARISE OUT OF OR RESULT
FROM  THE  ORDINARY, STRICT, SOLE OR CONTRIBUTORY NEGLIGENCE OF SUCH INDEMNITEE.

     (j)     In  relation  to  any  breach,  default  or  nonperformance  of any
representation,  warranty,  covenant or agreement made by a party hereto in this
Agreement, the exclusive relief and remedy available to the other parties hereto
in  respect  of said breach, default or nonperformance shall be (i) termination,
but  only  if  said  termination  is expressly permitted under the provisions of
Section 11.1, or (ii) indemnification as provided in this Section 12.4, but only
- ------------                                              ------------
to  the  extent  properly  claimable  hereunder and as limited pursuant hereto."

            -----------
with  Exhibit  A  attached  hereto.

     10.     EXHIBIT  D.   Exhibit  D  shall  be  deleted  in  its  entirety and

             ------------------------------------------

this  Second  Amendment,  the  terms and provisions of the Original Agreement as
amended  by  the  First  Amendment  are  in  full  force  and  effect.

     16.     BINDING  EFFECT.  This  Second  Amendment shall be binding upon the
