    a gas well (the Well), liable for conversion and fraud for its

    that Texas law does not support a tort action for conversion or

    I
    FACTS AND PROCEEDINGS
    Samson is lessee and operator of the Well by virtue of several
    oil and gas leases covering lands within the Samson Trammel Trust
    Gas Unit # 1 (the Unit).       The Unit covers 704 acres of the William
    Johns Survey A-39 in Polk County, Texas.
    Beginning in 1980, Samson acquired oil and gas leases from
    Exxon,   Republic   National    Bank,    Trustee,   and   the   Intervenors,
    covering most of the mineral interests that would eventually
    constitute the Unit.2    Samson drilled the Well and began producing
    it in 1981.     As permitted by the pooling clauses in the leases,
    Samson established the Unit by filing a Unit Designation in the
    public records of Polk County on February 27, 1984.
    It turned out, however, that Samson had failed to obtain oil
    and gas leases covering approximately five percent of the mineral
    interests   comprising   the    Unit.     Beginning   in   1989,   Mitchell
    obtained leases covering these unleased mineral interests while
    2
    In many cases, the Intervenors are heirs of the           original
    lessors. In addition, two of the Intervenors' leases            were
    obtained in 1973 by Highland Resources, Inc and later           assigned to
    Samson. Samson obtained ratification of these leases            in 1980.
    2
    acquiring other leases in the course of doing title work in and
    around the Unit area for the purposes of its own drilling.            That is
    how Mitchell came to own an unleased mineral interest in the Unit.
    As stipulated at trial, ownership of the Unit is as follows3:
    Mitchell Energy Corporation               4.93323%
    Intervenors                               5.55961%
    Republic National Bank, Trustee          82.94986%
    Exxon                                     5.20014%
    From 1981 to 1994, the Unit produced gross revenue of over $15
    million.4    Although Exxon and Republic National Bank, Trustee were
    paid royalties pursuant to their leases, the Intervenors were not
    paid royalties, and Mitchell was not paid its share of profits
    (gross production less expenses) as an unleased cotenant.             Samson
    neither notified Mitchell or Intervenors of the well production nor
    sent division orders to Intervenors for execution.
    Mitchell made its first demand for an accounting on February
    5, 1991.         After Samson refused this demand, Mitchell filed an
    action in Texas state court for an accounting, as well as damages
    for conversion and "fraudulent taking."             This action was later
    removed     to    federal   district   court   by   Samson   on   grounds    of
    diversity.       Upon learning of the Well from Mitchell, Intervenors
    joined the suit and asserted that Samson had breached their leases
    and committed fraud and conversion.            Prior to their joining the
    3
    These ownership percentages total to only 98.64284%.             The
    owners of the remaining 1.35716% remain unknown.
    4
    The Railroad Commission records reflecting the volume of
    gas produced from this well are available to the public.
    3
    suit, Intervenors had made no demand on Samson.
    The two sides paint diametrically opposed pictures of Samson's
    motives and conduct. Samson presented evidence at trial, including
    several title opinions, indicating that the reason Mitchell and
    Intervenors had not been paid was because the ownership of those
    mineral estates was not clear and royalties attributable to the
    questionable estates were being held "in suspense" until Samson was
    certain of the true ownerships. Mitchell and Intervenors countered
    with expert testimony that there was no title dispute in 1980, the
    year in which Samson began work on the Well, and that Samson had
    sufficient information to determine the correct ownership of these
    minerals.
    The money due the allegedly unknown owners was not segregated
    or placed in an escrow account by Samson.     Instead, Samson used
    these funds in its own business, a practice which Samson insists is
    common in the industry.    Some of these funds were distributed by
    Samson to other working interest owners of the well who were
    affiliates of Samson.   Neither did Samson make accounting entries
    on its books to reflect the suspension of these funds.      Samson
    describes this bookkeeping omission as a failure of communication
    among its employees;      the Appellees describe it as intentional
    obfuscation.
    The jury found against Samson on both the conversion and fraud
    claims and assessed actual damages of $1,354,752.11 for Mitchell
    and $1,664,222.80 for the Intervenors.    The jury also found that
    Samson had repudiated the Intervenors' leases.    Accordingly, the
    4
    actual damages for the Intervenors were calculated as if they were
    unleased cotenants rather than lessors under the lease agreements.
    Punitive damages in the amounts of $10 million and $40 million were
    awarded    to      Mitchell   and   the    Intervenors,   respectively.   In
    addition, the judgment of the district court enjoins Samson to pay
    Mitchell and Intervenors 100 percent of their mineral percentages
    in the future, without deduction for expenses, and awards Mitchell
    attorneys' fees of $65,718.75 pursuant to the Eastern District
    Civil Justice and Delay Reduction Plan.
    Samson filed a Motion for Judgment as a Matter of Law and a
    Motion for a New Trial, both of which were denied.                Samson now
    appeals.

    ANALYSIS
    A. STANDARD   OF   REVIEW
    A jury's findings of fact will not be overturned unless the
    facts and inferences point so strongly and overwhelmingly in favor
    of one party that the court believes that reasonable jurors could
    not arrive at a contrary verdict.5              We review a district court's
    application of state law de novo.6             Most of the relevant facts in
    this case are uncontested, and this opinion focuses primarily on
    the district court's determination and application of Texas law.

    Mitchell's    predecessors           had   not   leased    their    mineral
    interests in the Unit to Samson or anyone else.                  Thus, as the owner
    of undivided mineral interests in the Unit, Mitchell is Samson's
    unleased cotenant and was properly treated as such by the district
    court.
    The Intervenors, on the other hand, had leased their mineral
    interests in the Unit to Samson.                  The jury found, however, that
    Samson had repudiated these leases.7                    Thus, the district court
    treated the Intervenors as unleased cotenants, rather than as
    lessors under the lease agreements, which Samson contends was
    error.      We agree.
    In Texas, an oil and gas lease conveys an estate in real
    property to the lessee, namely, a fee simple determinable in the
    mineral estate.8        Samson thus retains title to the minerals under
    its   leases    for     as   long   as   production         in   paying     quantities
    continues.       Absent      a   specific       lease   clause   to   the    contrary,
    nonpayment of royalty does not terminate an oil and gas lease;                     the
    lessor's sole remedy lies in an action for damages based on breach
    of covenant.9
    The leases in the instant case contain no clause providing for
    7
    Interrogatory No. 3 defined "repudiation" to mean "when a
    party indicates by its words or actions that it is not going to
    perform its obligations under an agreement or lease and shows a
    fixed intention to abandon, renounce and refuse to perform the
    agreement or lease without just excuse."

    termination    upon   the   failure   to   pay    royalty.           Moreover,    all
    conditions necessary for Samson to retain the fee (i.e., production
    in   paying   quantities)    have   been   satisfied.              Therefore,    even
    assuming that Samson's failure to pay royalties to the Intervenors
    was intentional, as a matter of law this conduct could not result
    in Samson's mineral estate terminating and reverting back to the
    Intervenors.
    Intervenors, insisting that Texas law permits an oil and gas
    lease to be repudiated in these circumstances, erroneously rely on
    cases discussing the doctrine of repudiation.10                       That doctrine
    provides that a lessor may be estopped from asserting that a lease
    has terminated as a result of the lessee 's nonperformance when the
    lessor has directly contributed to that nonperformance.11                       Thus,
    this doctrine relieves a lessee from any obligation to conduct
    operations which are necessary to maintain the lease while a
    judicial resolution of the controversy between the lessee and
    lessor over the validity of the lease is pending.12                    The doctrine
    of repudiation, however, provides no support for Intervenors'
    position that Samson, the lessee, has repudiated these leases.
    Furthermore, the other cases relied on by Intervenors involve the
    rescission of ordinary bilateral contracts—as opposed to oil and
    10

    7
    gas leases, which convey estates in realty—and are therefore
    inapposite.     Thus, we conclude as a matter of law that Samson's oil
    and gas leases—mineral estates—have not terminated by repudiation
    or otherwise, so that Intervenors must be treated as lessors under
    oil and gas leases, not as unleased cotenants.
    C. CONVERSION
    Under Texas law, a party commits conversion if it exercises
    wrongful dominion and control over personal property belonging to
    another.13    The right to payment for minerals already severed from
    the ground is considered personal property, not realty.14     Mitchell
    and Intervenors thus argue that the jury properly found Samson
    liable for the tort of conversion for failing to pay them the
    amounts they were owed.      We disagree, concluding that Texas law
    does not support a tort action for conversion of the proceeds of
    mineral production under these circumstances.
    As for Mitchell, it and Samson are cotenants in the mineral
    interests within the Unit.       A unique legal relationship exists
    between cotenants.     Unlike one who is not a party to the cotenancy,
    any cotenant has the right to extract minerals from the common
    property without consent or participation of the other cotenants.15
    This right is subject only to a duty to account for the other

    cotenants' proportionate part of the value of the oil and gas
    produced,       less   their     proportionate       part     of    the   drilling   and
    operating expenses.16          Thus, the parties do agree that Samson did
    not convert gas by producing it and selling it.17                         Instead, the
    issue is whether a tort action lies against Samson for converting
    the proceeds of the gas sales when it failed to pay Mitchell.                          We
    conclude that no conversion action lies.
    Mitchell has not cited, and we have not found, a Texas case
    that has held one cotenant liable for the tort of conversion for
    failing to pay another cotenant the profits to which that other
    cotenant        is   entitled.       The     law,     of    course,       provides   the
    nonconsenting        cotenant     a remedy—the        right    to    an   accounting.18
    Moreover,        a   Texas   statute       also     allows,    at     least    in    some
    circumstances, the recovery of interest and attorneys' fees when
    recovering these amounts due.19 This right to an accounting for the
    profits of production, however, is not a tort remedy for which
    punitive damages are available.
    Similarly, the authorities relied on by Mitchell fail to
    16
    
    Id. 17 Samson
    argues that Mitchell's concession on this point is
    fatal because Interrogatory No. 1 asked whether Samson
    "intentionally converted property or revenues." Samson thus
    essentially contends that this interrogatory was based on two
    theories, the first of which (i.e., conversion of real property)
    was not legally sound. We find this argument unpersuasive in
    that
    we do not interpret this interrogatory to be based upon two legal
    theories.
    18
    E.g., Cox v. Davison, 
    397 S.W.2d 200
    (Tex.1965).
    19
    See Tex.Nat.Res.Code Ann. §§ 91.401-91.406.
    9
    support    the    contention       that     conversion      is    a    proper    remedy.
    Although it is certainly true that the Texas courts have found that
    the proceeds from the sale of oil and gas can be the subject of
    conversion, each case in which the courts of Texas have so held
    involved a trespasser or other person with no legal right in and to
    the minerals.20        As discussed above, however, a cotenant has the
    legal right to extract and sell minerals from the common property.
    Thus, this line of cases lacks relevance to the issue before us.
    Similarly,       the    Gardner     Machinery      case,     which      involved     the
    conversion of sale proceeds by an agent selling particular items of
    machinery owned by its principal, is also inapposite.21
    Texas law does recognize that one cotenant may have an action
    for   conversion        against    another       cotenant    in       certain    limited
    circumstances.         Thus, "a suit for conversion may be maintained by
    one   tenant     in    common     against    another     tenant        in   common   who
    appropriates the entire property owned in common between them."22
    We note that in Grabes the property owned in common was machinery;
    profits from real property were not involved.                    The rule announced
    in that case is inapplicable to the situation at hand.                          The most
    that can be said for the instant case is that only proceeds of
    20

    10
    production have been "appropriated," not the entire mineral estate
    owned by the cotenants.          Therefore, the unique situation under
    which one cotenant may have an action for conversion against
    another cotenant is not present.
    Mitchell, Intervenors, and Samson all argue that the line of
    cases involving money as the subject of conversion supports their
    respective positions on this issue. Texas jurisprudence holds that
    money can be the subject of conversion, but only when it is in the
    form of specific chattel, such as old coins, or when "the money is
    delivered to another party for safekeeping, the keeper claims no
    title, and the money is required and intended to be segregated,
    either substantially in the form in which it was received or as an
    intact fund."23     An obligation to pay money generally, however, is
    treated differently under Texas law.         "Where money is involved, it
    is   subject   to   conversion    only    when   it   can   be   described   or
    identified as a specific chattel, but not where an indebtedness may
    be discharged by the payment of money generally."24
    We first note that none of these "money conversion" cases
    involves the right of a cotenant with respect to profits from the
    common property.       Thus, these cases are not truly on point.
    23
    Dixon v. State,

    , 723 (Tex.App.—Austin 1991,

    York, 
    568 S.W.2d 139
    , 144 (Tex.Civ.App.—Tyler 1978, writ ref'd
    n.r.e.) (holding that an employee could not recover against his
    employer on the theory of conversion when he did not seek return
    of specific money but was only seeking repayment of money
    generally which he alleged was wrongfully withheld from his
    commissions).
    11
    Although Mitchell does have a right to a percentage of the profits
    of production, this does not give Mitchell a right to a specific
    and identifiable portion of the proceeds received that could be
    considered specific chattel.       Rather, Mitchell's right is to an
    amount equal to its proportionate share of the value of gas
    produced, which is not necessarily the same as the amount of the
    sale proceeds less reasonable drilling and operating expenses.
    Therefore, regardless of the extent to which this line of cases may
    be relevant, we are satisfied that the obligation owed to Mitchell
    under the law of cotenancy is more analogous to an obligation to
    pay money generally than to return or deliver money as specific
    chattel. Moreover, this conclusion comports with the fact that the
    law of cotenancy provides no remedy for conversion under these
    circumstances.
    Mitchell further argues that Texas Property Code section
    75.102 supports a conversion action against a cotenant.           That
    section provides that "[a] holder of abandoned property shall
    preserve that property and may not by any procedure, including a
    deduction for service, maintenance, or other charge, transfer,
    convert, or reduce the property to the profits or assets of the
    holder."25     This unclaimed property statute has no application to
    the rights and remedies of cotenants.     Neither does the mere use of
    the word "convert" in an illustrative list somehow create a cause
    of action in tort where none exists independently. Therefore, this
    argument by Mitchell fails.
    25
    TEX.PROP.CODE ANN. § 75.102 (Vernon 1995) (emphasis added).
    12
    At oral argument, Mitchell conceded that normally the only
    remedy available in this type of situation is an action for an
    accounting. Mitchell insists, however, that this case is different
    because Samson neither made a bookkeeping entry to reflect that
    these funds were held in suspense nor placed them in escrow.     We
    are not convinced that the omission of these acts—which are not
    expressly required by law—can somehow transform a right to an
    accounting into the tort of conversion.   Accordingly, we conclude
    that Mitchell has no action in conversion against its cotenant,
    Samson, to recover its share of profits in the mineral estate.
    We reach the same conclusion as to Intervenors.   As discussed
    above, they are properly treated as Samson's lessors under the oil
    and gas leases, not as Samson's cotenants.   Their causes of action
    sound only in contract, and not in tort.26   Thus, Intervenors too
    have no claim for conversion.
    D. FRAUD
    The jury also found that Samson had committed fraud.     This
    finding was based on Samson's failure to disclose material facts
    (i.e., that money was owed to Mitchell and Intervenors as a result
    of gas production from the Well), which it purportedly had a duty
    to disclose pursuant to an asserted fiduciary relationship. Samson
    contends that such a position is not supported under Texas law—and
    we agree.
    Absent a fiduciary or confidential relationship, the failure
    26
    See Harrison v. Bass Enter. Prod. Co., 
    888 S.W.2d 532
    , 536
    (Tex.App.—Corpus Christi 1994, no writ).
    13
    to disclose information is not actionable as fraud.27        Under Texas
    law neither a cotenancy nor a lessor/lessee relationship imports a
    fiduciary relationship.28   Although a confidential relationship can
    arise not only from technical fiduciary relationships but from
    partnerships, joint ventures, and some informal relationships,29
    there is no evidence in this case to suggest the existence of some
    other relationship between Samson on the one hand and either
    Mitchell or Intervenors on the other that could support such a
    finding by the jury.
    Mitchell    contends   that   Samson   had   a   fiduciary   duty   of
    disclosure as a matter of law, arguing that the duty to account, by
    its very nature, includes the duty to disclose.          No authority is
    cited for this contention, and we have found none through our own
    research.     Mitchell's argument does not withstand scrutiny:           It
    emerges as simply an attempt to bootstrap a cotenant's right to an
    accounting into the tort of fraud based on failure to render an
    accounting.
    Mitchell further contends that Samson was a trustee of that

    14
    portion of the proceeds of production from the Well to which
    Mitchell was entitled.      Mitchell relies on a single phrase from a
    single Texas case in which it is stated that "rents and profits
    received   by    one   cotenant    are    held   by   him   in   trust   for   his
    cotenants."30 That case then goes on to state that for the cotenant
    to acquire title to these funds as a result of the running of the
    statute of limitations, the cotenant must have repudiated the
    trust.
    Mitchell's reliance on this isolated phrase is misplaced.
    True, the "in trust" language of the case makes clear that the one
    cotenant does not own the proceeds allocable to the other cotenant,
    and describes the implications for the statute of limitations.
    Nevertheless, this isolated and imprecise use of the word "trust"
    does not justify the stretch that would be required to approbate
    Mitchell's      assertion   that    a    cotenant's    failure     to    disclose
    information regarding an accounting results in a breach of a
    fiduciary duty which in turn can serve as the basis for the tort
    remedy of fraud. Other Texas cases that involve an accounting owed
    by a cotenant do not mention a fiduciary duty.
    We conclude that Samson had no confidential or fiduciary duty
    vis-à-vis Mitchell or Intervenors.            It follows that no actionable
    fraud could arise from Samson's failure to disclose information
    about production from the Well or to pay them their respective
    shares of the proceeds thereof.

    Paso 1980, writ ref'd n.r.e.) (emphasis added).
    15
    E. MODIFICATION   OF   JUDGMENT
    Samson concedes that, as a cotenant, Mitchell is entitled to
    an accounting for its share of the net proceeds of production, and
    that Intervenors are entitled to royalty payments in accordance
    with their lease agreements. Moreover, the parties have stipulated
    to minimum payments due based on evidence presented to the district
    court.      As the record evidence available to us is sufficient to
    permit a determination of the payments to which Mitchell and
    Intervenors are entitled on the basis of our holding, we need not
    remand this case to the district court for the calculation of
    various amounts due and entry of judgment therefor.
    1. Actual Damages for Mitchell
    In calculating the actual damages for Mitchell, the district
    court awarded an amount equal to Mitchell's ownership percentage of
    the gross revenues produced by the Well.        The court did not deduct
    Mitchell's share of expenses and taxes from the gross amount of the
    actual damages.          This was error.   Under Texas law, a producing
    cotenant must account to nonproducing cotenants "on the basis of
    the value of any minerals taken, less the necessary and reasonable
    costs of production and marketing."31          Thus, Mitchell's actual
    damages must take into consideration Mitchell's share of the
    operating expenses.
    Citing Mayfield v. de Benavides,32 Mitchell argues that Samson
    31
    
    Byrom, 717 S.W.2d at 605
    (emphasis added).

    (Tex.App.—San Antonio 1985, writ ref'd
    n.r.e.).
    16
    is a willful and deliberate converter who should not be able to
    recover costs of production.         Mayfield, however, holds that a bad
    faith trespasser      's   measure   of    damages   does   not   include   the
    recovery of drilling and operating costs.33 In addition to the fact
    that no finding was made that Samson was a bad faith trespasser,
    Samson's valid leases with Exxon and Republic National Bank,
    Trustee, would preclude such a finding as a matter of law.              Thus,
    the district court's damage calculation for Mitchell is wrong and
    must be reduced by Mitchell's share of drilling and operating
    costs, taxes, and the like.
    Based on the evidence in the record (and before taking into
    account prejudgment interest), the amount of actual damages payable
    to Mitchell, calculated through September 30, 1994, is $424,999.82.
    2. Actual Damages for the Intervenors
    The district court awarded actual damages to the Intervenors
    as though they were unleased cotenants, rather than royalty owners,
    based on the jury's finding that Samson repudiated the Intervenors'
    leases.     As with Mitchell, this calculation was not reduced by the
    Intervenors' share of expenses.
    That is immaterial as to Intervenors, though, because as a
    matter of law the nonpayment of royalty cannot support a finding
    that Samson repudiated their leases. Accordingly, the Intervenors'
    damages must equate with their royalty interests under their
    leases, not with the share of gross proceeds attributable to their
    fee ownerships, regardless whether or not the latter is reduced by
    33
    
    Mayfield, 693 S.W.2d at 506
    .
    17
    costs and expenses of production.
    In light of the evidence in the record (and before taking into
    account prejudgment interest), the amount of royalty payments due
    and   owing      to   Intervenors,   through    September   30,   1994,   is
    $109,035.17.34
    3. Prejudgment Interest
    The district court's judgment calculation included a Treasury
    bill (T-bill) rate of interest applied to the actual damages.             On
    top of that, prejudgment interest at a rate of 10 percent per annum
    was added to the damages, which already included interest, clearly
    constituting a double interest award.
    State law governs the award of prejudgment interest in
    diversity cases.35 Under Tex.Rev.Civ.Stat.Ann. art. 5069-1.05, the
    proper rate of prejudgment interest is 10 percent per annum, not a

    These actual damages are allocated among the Intervenors
    as follows:
    Bliss Interest                 $    3,336.60
    Mayo Interest                       5,735.31

    T-bill rate of interest.   Moreover, the district court erred in
    awarding a double recovery for the time value of money.36        As
    Mitchell and Intervenors all but concede, the damage award should
    include only one recovery for the time value of money, and that one
    recovery should be calculated using the statutory 10 percent per
    annum rate for prejudgment interest.37       Therefore, taking into
    account the correct rate of prejudgment interest through February
    2, 1995, the day before the district court's judgment was signed,
    the judgment for actual damages through September 30, 1994 is
    modified as follows:

    Mitchell                    $766,719.00

    entire judgment, which Mitchell and the Intervenors shall have and
    recover against Samson in the amount of $977,886, plus costs of
    court, shall      earn    interest       at    the   rate   of   7.03%,   compounded
    annually, beginning on February 3, 1995, the day the district
    court's judgment was signed, in accordance with 28 U.S.C. § 1961.39
    4. Punitive Damages
    Texas law requires the existence of an independent tort to
    support     an   award   of    punitive       damages.40     In    this   case,   the
    independent torts of conversion and fraud are not supported by
    Texas law.       The remedies to which Mitchell and Intervenors are
    entitled, flowing as they do from actions for an accounting and for
    breach of contract—and not from tort—do not supply a basis for
    38

    amount of the judgment, including prejudgment interest).

    20
    punitive damages.41    Therefore, the judgment with respect to the
    award of punitive damages is reversed and vacated.
    5. Additional Relief
    Under the heading "Additional Relief Granted," the district
    court "Orders that Samson Resources Company pay to Mitchell Energy
    Corporation 100% of its mineral interests and Intervenors 100% of
    their mineral interests based on future production after September,
    1994 for such time as the well in question produces in paying
    quantities, without allowance for deduction of expenses."
    The amounts ordered to be paid in this "additional relief"
    portion of the district court's judgment are incorrect.    Instead,
    as we have noted, Mitchell's future right is to receive timely its
    proportionate part of the proceeds of production less reasonable
    operating expenses;     and Intervenors' future right is to receive
    royalty payments timely, pursuant to the terms of their respective
    lease agreements.     In light of our reversal of the judgment that
    was premised on the theories of conversion and fraud and the fact
    that the parties have an adequate remedy at law, we see no need to
    remand this "additional relief" aspect of the district court's
    judgment for disposition by that court.   Accordingly, the judgment
    with respect to the "additional relief" is reversed and vacated.
    6. Attorneys' Fees
    The district court's judgment also awards Mitchell attorneys'
    fees in the amount of $65,718.75 pursuant to the Eastern District
    of Texas Civil Justice and Delay Reduction Plan (Eastern District
    41
    See 
    id. 21 Plan).42
      The sole foundation for Mitchell's attorneys' fees claim
    is its letter of November 15, 1993.    Mitchell contends that this
    letter constitutes an "offer of judgment" within the meaning of the
    Eastern District Plan.   Samson counters that Mitchell's letter is
    not sufficient, that it is merely a settlement proposal.   We agree
    with Samson.
    The letter in question states Mitchell's belief that it is
    "entitled to receive in settlement of the matter the sum of
    $246,093.06 for past production plus $143,921.13 as pre-judgment
    interest at the rate of 10%."     The next sentence in the letter
    42
    The relevant portion of the Eastern District of Texas
    Civil Justice and Delay Reduction Plan reads as follows:
    Article Six. Miscellaneous Matters
    (9) Offer of Judgment. At the Management
    Conference or anytime thereafter, a party may make a
    written offer of judgment. If the offer of judgment is
    not accepted and the final in the case is of more
    benefit to the party who made the offer by 10%, then
    the party who rejected the offer must pay the
    litigation costs incurred after the offer was rejected.
    In personal injury and civil rights cases involving
    contingent attorneys' fees, the award of litigation
    costs shall not exceed the amount of the final
    judgment. The Court may, in its discretion, reduce the
    award of litigation costs in order to prevent undue
    hardship to a party.
    "Litigation costs" means those costs which are
    directly related to preparing the case for trial and
    actual trial expenses, including but not limited to
    reasonable attorneys' fees, deposition costs and fees
    for expert witnesses.
    The party who makes an offer of judgment shall set
    forth the deadline by which the offer must be accepted.
    The deadline must be reasonable. If the offer is not
    accepted in writing by the deadline, the offer is
    deemed rejected on that day.
    22
    contains an offer to settle the case by having Mitchell sell its
    working   interest   to   Samson   for   approximately   $91,000,   with
    conditions on the royalty interest.        And the sentence after that
    proposes, as an alternative to sale, that the parties enter into an
    operating agreement.
    More significant than what Mitchell's letter says is what it
    does not say:    It makes no reference to offering a "judgment";      it
    appears to contemplate future negotiations; and it is also unclear
    whether this settlement offer is conditioned on entering a sale or
    an   operating   agreement.    Additionally,    although   the   Eastern
    District Plan does not specify a format or require any "magic
    words" for an offer of judgment, it does provide that the offer
    must specify a deadline.       The closest thing to a deadline in
    Mitchell's letter is the closing sentence which states, "I look
    forward to hearing from you this week."        It would be too great a
    stretch to call this imprecise language—which appears to be little
    more than a courteous salutation—a deadline, particularly given the
    other shortcomings of Mitchell's letter.
    These observations lead us to conclude that Mitchell's letter
    does not rise to the level of an "offer of judgment" within the
    contemplation of the Eastern District Plan. Accordingly, the award
    of attorneys' fees for Mitchell is vacated.
    III
    CONCLUSION
    Samson failed to disclose or pay the amounts owed to Mitchell
    and Intervenors as a result of gas production from the Well.          As
    23
    Samson's cotenant, Mitchell's remedy is an action for an accounting
    of its proportionate share of the Well's profits, i.e., the value
    of the gas produced less drilling and operating expenses.        As
    Samson's lessors, Intervenors' remedy is a breach of contract claim
    against Samson for the royalty payments owed to them pursuant to
    the terms of their respective lease agreements.   Under Texas law,
    Samson retains the mineral estate conveyed to it by the oil and gas
    leases entered into with the Intervenors. Neither Mitchell nor the
    Intervenors can maintain an action in tort against Samson for
    conversion or fraud under these circumstances, and absent an
    independent tort, punitive damages do not lie.     As the evidence
    before the court is sufficient to enable us to calculate the
    damages for which Samson is liable based on our holdings, the
    judgment of the district court is reversed and vacated in part,
    modified in part, and, as modified, rendered, as follows:    Samson
    to pay Mitchell $766,719, plus costs of court, plus post-judgment
    interest from February 3, 1995, until paid in full, at the rate of
    7.03% per annum;      and Samson to pay Intervenors $206,167, plus
    costs of court, plus post-judgment interest from February 3, 1995,
    until paid in full, at the rate of 7.03% per annum.
    REVERSED and VACATED in part;     MODIFIED in part;    and, as
    modified, RENDERED.
