    (December 21, 1993)
    Before WIENER and EMILIO M. GARZA, Circuit Judges, and LITTLE*,
    District Judge.
    EMILIO M. GARZA, Circuit Judge:
    Defendants Ellis Ray Thomas ("Thomas"), Jerry Thomas Maxwell
    ("Maxwell"), Steven Darrel Gregg ("Gregg"), Modesto Serna Sanchez,
    Jr. ("Sanchez"), and Roy Lee Hodgkiss ("Hodgkiss") were jointly
    tried before a jury and convicted of various offenses stemming from
    a conspiracy to distribute narcotics.       Thomas, Maxwell, Gregg, and
    Sanchez were convicted of conspiring to possess a controlled
    substance with intent to distribute, in violation of 21 U.S.C. §§
    *
    District Judge of the Western District of Louisiana, sitting by
    designation.
    841(a)(1) and 846 (1988).          The jury also found Thomas and Sanchez
    guilty   of    possessing     a    controlled         substance    with     intent   to
    distribute and aiding and abetting such possession, in violation of
    21 U.S.C. § 841(a)(1) and 18 U.S.C. § 2.                Additionally, Sanchez was
    found guilty of money laundering and aiding and abetting money
    laundering, in violation of 18 U.S.C. §§ 1956(a)(1)(A)(i) and 2.
    Hodgkiss   was    convicted       of   engaging       in    a   continuing   criminal
    enterprise ("CCE"), in violation of 21 U.S.C. § 848(a)(1), and of
    using or carrying a machine gun in relation to a drug trafficking
    offense,   in    violation    of       18    U.S.C.    §    924(c)(1).       All   five
    defendants now appeal their convictions and sentences.                       We affirm
    in part and reverse and remand in part.
    I
    From 1986 to 1989, Hodgkiss operated an extensive conspiracy
    to distribute cocaine, amphetamine, methamphetamine, and marijuana
    in   central    Texas.      Hodgkiss        employed       many   people,    including
    government witnesses Aaron Clark and Robbie Curtis, to store,
    transport, and distribute controlled substances. To facilitate the
    purchase and sale of narcotics, and to insulate the conspiracy from
    detection by law enforcement personnel, Hodgkiss devised a code
    system utilizing digital pagers. Hodgkiss assigned code numbers to
    various people,1 types of drugs, and locations where the sales were
    1
    John Rogala and his associates were "01"; Alan Gardner
    and his associates were "03"; Sanchez was "06"; Thomas was "07";
    Vance Zimmerman was "10"; Wesley Schneider was "13"; Clark was
    "14"; Curtis was "17"; Keith and Angela Norman were "26"; and
    Donald Copeland was "333". The government was unable to discover
    -2-
    to be consummated.        Customers would contact Hodgkiss to set up a
    drug deal.      Hodgkiss then would use the pagers to notify his
    employees that, for example, person "01" would be waiting at
    location    "01"   to   purchase   a   specified    amount    of   drug   "01."
    Hodgkiss kept records detailing many of the drug transactions he
    arranged.
    Hodgkiss obtained the drugs distributed by his retailers from
    various sources.        John Rogala provided Hodgkiss with much of the
    cocaine distributed by the conspiracy, while Alan Gardner sold
    large quantities of methamphetamine to Hodgkiss.2                  Eventually,
    Hodgkiss and Rogala began manufacturing methamphetamine themselves
    at a laboratory they established near Smithville, Texas.              Hodgkiss
    and Rogala also attempted to import large quantities of marijuana
    into the United States from Mexico, although they ultimately were
    unsuccessful.
    An investigation by local and federal authorities led to the
    arrests of twenty-nine participants in the Hodgkiss conspiracy,
    including the defendants, all of whom were charged in an indictment
    alleging a number of drug-related offenses.3          A jury found the five
    the identities of "09", "10", and "69".
    2
    Hodgkiss also arranged purchases of drugs from David LeBoeuf, Joe
    Reed, Kanetha Childers, Diane Watson, Clyde McCullar, and Billy Basham.
    3
    On December 14, 1989, agents seized from Hodgkiss's home drug
    ledgers, a list of code numbers and telephone numbers assigned to Hodgkiss's
    distributors, a small amount of methamphetamine, over $20,000 in cash, a
    telephone scrambling device, and firearms.     Agents already had seized drug
    ledgers, methamphetamine, marihuana, and other narcotics from Gregg's home.
    Agents who searched Sanchez's residence in March 1990 seized a scale of the type
    commonly used to weigh drugs, a trunk containing marihuana residue, and a
    telephone scrambling device. Agents searching Maxwell's house seized several
    -3-
    defendants guilty of all charged offenses. The district court then
    sentenced Thomas to a prison term of 240 months.                           Maxwell received
    a    term    of   124    months.         Gregg       received    a   324    month    term    of
    imprisonment.           The district court sentenced Sanchez to a prison
    term of 240 months, and Hodgkiss to life imprisonment.                                      The
    defendants now appeal their convictions and sentences.
    II
    Joint Claims
    A
    All five defendants generally argue that the evidence proved
    the    existence        not   of    the    single       conspiracy         alleged   in     the
    indictment, but of multiple conspiracies.                            Gregg specifically
    argues that there was a "material variance" between the single
    conspiracy alleged in the indictment and the multiple conspiracies
    proved by the government at trial.                     A conspiracy is "an agreement
    by two or more persons to commit one or more unlawful acts and an
    overt       act   by    one   of   the    conspirators          in   furtherance     of     the
    conspiracy."           United States v. Romeros, 
    600 F.2d 1104
    , 1106 (5th
    Cir. 1979), cert. denied, 
    444 U.S. 1077
    , 
    100 S. Ct. 1025
    , 
    62 L. Ed. 2d
    759 (1980).            A conspiracy conviction must be upheld if any
    reasonable trier of fact could find beyond a reasonable doubt that
    "a    conspiracy        existed,     that        each    co-defendant        knew    of     the
    conspiracy, and that each co-defendant voluntarily joined it."
    United States v. Simmons, 
    918 F.2d 476
    , 483-84 (5th Cir. 1990)
    hand scales, firearms, and a cocaine grinder.
    -4-
    (internal quotation omitted).      "No evidence of overt conduct is
    required.     A conspiracy agreement may be tacit, and the trier of
    fact may infer agreement from circumstantial evidence."            United
    States v. Hernandez-Palacios, 
    838 F.2d 1346
    , 1348 (5th Cir. 1988).
    "In general, once an indictment has been returned, its charges
    may not be broadened through amendment except by the grand jury."
    United States v. Baytank (Houston), Inc., 
    934 F.2d 599
    , 606 (5th
    Cir. 1991).     A material variance occurs when a variation between
    proof and indictment occurs, but does not modify an essential
    element of the offense charged.      
    Id. "With variance,
    our concern
    is whether the indictment, assuming it has otherwise alleged the
    elements of the offense, has so informed a defendant that he can
    prepare his defense without surprise and has protected him against
    a second prosecution for the same offenses."            United States v.
    Cochran, 
    697 F.2d 600
    , 604 (5th Cir. 1983).      If a material variance
    occurs, we determine whether the defendant has been prejudiced by
    it using the harmless error analysis.       United States v. Lokey, 
    945 F.2d 825
    , 832 (5th Cir. 1991).
    Whether the evidence, or the reasonable inferences drawn
    therefrom, proved one or more conspiracies turns on the following
    elements:   (1) the time period involved, (2) the persons acting as
    co-conspirators,    (3)   the   statutory    offenses   charged   in   the
    indictment, (4) the nature and scope of the criminal activity, and
    (5) the places where the events alleged as the conspiracy took
    place.   
    Lokey, 945 F.2d at 831
    ;    United States v. Devine, 934 F.2d

    1325, 1333 (5th Cir. 1991), cert. denied, ___ U.S. ___, 
    112 S. Ct. 954
    , 
    117 L. Ed. 2d 120
    (1992).        Here, the jury was presented with
    evidence from which it could reasonably infer that the defendants
    were involved in a single conspiracy between 1986 and 1989.              For
    example, Clark and Curtis both testified that they delivered drugs
    at Hodgkiss's direction to Thomas and Sanchez during the relevant
    time period. Curtis also testified that he obtained his "job" with
    Hodgkiss through Alan Gardner, who often would collect the proceeds
    of drug sales from Curtis for Hodgkiss.          Moreover, Gardner would
    inform Curtis of the pick-up locations for methamphetamine that
    Hodgkiss purchased. Additionally, Clark testified that John Rogala
    and Patrick Palmer set up the Smithville methamphetamine laboratory
    at Hodgkiss's direction and that Rogala brought the methamphetamine
    produced at the laboratory to Clark for distribution pursuant to
    Hodgkiss's directions. Palmer stated that Rogala introduced him to
    Hodgkiss and that Hodgkiss and Rogala jointly reimbursed him for
    expenses he incurred while leasing the Smithville property. Edward
    Crawford,   who   oversaw   the   manufacture   of   methamphetamine     for
    Hodgkiss, testified that he was paid for his services by Hodgkiss
    through   Gardner.    Donald      Copeland   testified   that   Rogala   and
    Hodgkiss attempted to smuggle a large quantity of marijuana into
    the United States from Mexico.         Gardner testified that he often
    purchased narcotics from Hodgkiss and that Hodgkiss knew Gardner
    would be distributing the drugs to others, including Maxwell.
    Richard Townsen, one of Rogala's employees, testified that Gregg
    -6-
    delivered up to fifteen kilograms of cocaine to him, many of which
    Rogala then delivered to Hodgkiss.               Finally, Norman Allanson
    testified that Gregg transported fifteen kilograms of cocaine that
    Rogala had purchased from Florida to Texas.
    Nonetheless, the defendants assert that because they did not
    know the identity of other members of the Hodgkiss conspiracy, they
    could not be guilty of conspiring with them.             However, a jury may
    find a defendant guilty of conspiring with unknown persons where a
    sufficient overlap of personnel occurs))i.e., "if a pivotal figure,
    such as [Hodgkiss], directs and organizes the illegal activity, and
    has extensive dealings with each of the parties."                 
    Lokey, 945 F.2d at 833
    .     Thus, "[p]arties who knowingly participate with core
    conspirators to achieve a common goal may be members of an overall
    conspiracy,"      even    in    the   absence    of     contact      with    other
    conspirators. United States v. Richerson, 
    833 F.2d 1147
    , 1154 (5th
    Cir. 1987) (internal quotation omitted).             Therefore, as noted, the
    jury's    conclusion     that   Hodgkiss,   Gregg,     Sanchez,      Thomas,     and
    Maxwell    were   co-conspirators     was   reasonable       in    light    of   the
    evidence presented at trial.
    Moreover, the jury reasonably could have inferred from the
    evidence that the defendants had a common goal of distributing
    illegal drugs for profit, that they knew they were part of a larger
    venture,    and   that    the   activities      of    each   conspirator         were
    advantageous to the success of the overall venture:
    Where the activities of one aspect of the scheme are
    necessary or advantageous to the success of another
    -7-
    aspect of the scheme or to the overall success of the
    venture, where there are several parts inherent in a
    larger common plan, or where the character of the
    property involved or nature of the activity is such that
    knowledge on the part of one member concerning the
    existence and function of other members of the same
    scheme is necessarily implied due to the overlapping
    nature of the various roles of the participants, the
    existence of a single conspiracy will be inferred.
    United States v. Elam, 
    678 F.2d 1234
    , 1246 (5th Cir. 1982).                  "[I]n
    many narcotics distribution networks the ultimate retailers may not
    know the identities of those who supply their wholesaler, and the
    retailers' identities may be unknown to those suppliers;                   but all
    are       well   aware   that   they    are   participating    in   a   collective
    venture."         
    Lokey, 945 F.2d at 831
    (internal quotation omitted).
    The jury reasonably could have found that the defendants were part
    of a single conspiracy:                Gregg as a supplier, Hodgkiss as a
    wholesaler, and Thomas, Maxwell, and Sanchez as retailers.                   Thus,
    we find that the jury convicted the defendants only of the single
    conspiracy charged, not the multiple conspiracies defendants allege
    existed.4
    4
    In fact, the district court specifically instructed the jury that
    [i]f you find that the conspiracy charged did not exist, then you
    must return a not guilty verdict as to each Defendant . . . , even
    though you find that some other conspiracy or conspiracies existed.
    If you find that a defendant was not a member of the conspiracy
    charged in the indictment, then you must find that Defendant not
    guilty, even though the Defendant may have been a member of some
    other conspiracy.
    This instruction, which substantially tracks our Pattern Jury Instructions, does
    not permit the jury to convict the defendants for crimes not charged in the
    indictment. See Zafiro v. United States, ___ U.S. ___, 
    113 S. Ct. 933
    , 939, 
    122 L. Ed. 2d 317
    (1993) (noting that "`juries are presumed to follow their
    instructions'") (quoting Richardson v. Marsh, 
    481 U.S. 200
    , 209, 
    107 S. Ct. 1702
    ,
    1708, 
    95 L. Ed. 2d 176
    (1987)).
    -8-
    Finally, even if the evidence did prove the existence of
    multiple conspiracies, the defendants, to obtain reversal, still
    must demonstrate that the variance affected their substantial
    rights.      Here, we find that the indictment sufficiently informed
    the defendants of the offenses charged and that they were not
    surprised at trial.           See 
    Cochran, 697 F.2d at 604
    .             Nor were the
    convictions based upon a "set of facts distinctly different from
    that set forth in the indictment."               United States v. Chandler, 
    858 F.2d 254
    ,    257   (5th   Cir.   1988)      (internal     quotation    omitted).
    Accordingly, if any material variance occurred, we find that it was
    harmless error.          See 
    Lokey, 945 F.2d at 834
    ; see also United States
    v.   Jackson,      
    978 F.2d 903
    ,    911    (5th   Cir.    1992)    ("[W]hen   the
    indictment alleges the conspiracy count as a single conspiracy, but
    the `government proves multiple conspiracies and a defendant's
    involvement in at least one of them, then clearly there is no
    variance        affecting     that      defendant's     substantial       rights.'")

    B
    The defendants contend that the evidence was insufficient to
    support their          respective    convictions       for    various   drug-related
    offenses. However, they failed to move for a judgment of acquittal
    at the close of their cases.5             Accordingly, we restrict our review

    Maxwell and Gregg moved for a judgment of acquittal at the close of
    the government's case, but not at the close of their cases.
    -9-
    of their claims to whether their convictions resulted in a manifest
    miscarriage of justice.              United States v. Vaquero, 
    997 F.2d 78
    , 82
    (5th Cir.), petition for cert. filed (1993);                        United States v.
    Galvan, 
    949 F.2d 777
    , 782 (5th Cir. 1991).                     "Such a miscarriage
    would exist only if the record is devoid of evidence pointing to
    guilt, or . . . [if] the evidence on a key element of the offense
    was so tenuous that a conviction would be shocking."                       
    Galvan, 949 F.2d at 782-83
    (citations omitted). "In making this determination,
    the   evidence,      as     with      the   regular     standard     for   review    of
    insufficiency of evidence claims, must be considered `in the light
    most favorable to the government, giving the government the benefit
    of all reasonable inferences and credibility choices.'"                           United
    States   v.    Ruiz,      
    860 F.2d 615
    ,     617   (5th   Cir.   1988)      (quoting
    
    Hernandez-Palacios, 838 F.2d at 1348
    ).                   Moreover, "[o]nly slight
    evidence      is   needed       to   connect     an    individual    to    an   illegal
    conspiracy once the [government] has produced evidence of that
    conspiracy."       
    Vaquero, 997 F.2d at 82
    .
    1
    Maxwell contends that the evidence is insufficient to support
    his conviction for conspiracy to possess controlled substances with
    intent to distribute.                However, Alan Gardner))who at one time
    supplied Hodgkiss with drugs but later began purchasing drugs at
    wholesale prices from Hodgkiss))testified that he began selling
    cocaine to Maxwell in March 1988.                  Gardner stated that although
    Maxwell usually purchased two ounces of uncut cocaine every other
    -10-
    week, Maxwell on occasion would order up to four ounces.              Moreover,
    Gardner normally      "fronted"6 the       cocaine   to   Maxwell.      Gardner
    employee Charles Barton corroborated Gardner's testimony.                Ronald
    McWilliams, who at one time supplied cocaine to Maxwell, testified
    that he purchased cocaine from Maxwell on two occasions in 1989.
    The jury could have concluded from this evidence that Maxwell
    was a member of the Hodgkiss conspiracy.             Maxwell received uncut
    cocaine from Gardner, who purchased cocaine from Hodgkiss with
    Hodgkiss's knowledge that the cocaine would be resold.                Moreover,
    Gardner also fronted the cocaine to Maxwell, allowing the jury to
    infer that Maxwell was acting as a retailer of the cocaine.                This
    inference is supported by the testimony of McWilliams, who stated
    that    he   purchased    cocaine    from    Maxwell      on   two   occasions.
    Accordingly, Maxwell's conviction did not result in a manifest
    miscarriage of justice.
    2
    Gregg also argues that the evidence did not support his
    conviction for conspiracy to possess with intent to distribute.
    However, Richard Townsen, who worked for Rogala, testified that on
    several occasions Gregg delivered multiple kilograms of cocaine to
    6
    "The term `fronted' refers to a transfer of drugs in which one person
    transfers the drugs to a second person in return for the second person's promise
    to pay the sales price within a few days." United States v. Alfaro, 
    919 F.2d 962
    , 963 (5th Cir. 1990); see also United States v. Chase, 
    838 F.2d 743
    , 746
    (5th Cir.) (defining "fronted" to mean "delivered on consignment"), cert. denied,
    
    486 U.S. 1035
    , 
    108 S. Ct. 2022
    , 
    100 L. Ed. 2d 609
    (1988). Thus, the jury may
    reasonably infer that if a person has been fronted drugs, that person likely is
    a dealer who intends to sell all or a portion of the drugs in order to pay the
    drug supplier.
    -11-
    him that had been purchased by Rogala.                   Pursuant to instructions
    from Rogala, Townsen would park his truck at a specified location
    and then "disappear" for a couple of hours.                     Gregg, who obtained
    the keys to Townsen's truck from Rogala, would place the cocaine in
    the truck during Townsen's absence. Norman Allanson testified that
    he sold cocaine to Rogala and Grey Hayes.7                  On one occasion, Gregg
    transported eight kilograms of cocaine from Florida to Texas for
    Rogala.    On a second occasion, Gregg transported seven kilograms
    from Florida to Texas for Rogala.                   On a third occasion, Gregg
    transported a sizable quantity of marijuana to Florida, picked up
    five kilograms of cocaine from Allanson, but sold some of the
    cocaine in Florida when he was not able to sell the marijuana.
    Consequently, viewing the evidence in the light most favorable to
    the government, Gregg's conviction did not result in a manifest
    miscarriage of justice.         See United States v. Greenwood,

    Thomas contends that the evidence was insufficient to support
    his conspiracy conviction.        Curtis, however, testified that while
    he worked for Hodgkiss, he delivered one to two ounce quantities of
    controlled substances to Thomas twice a week.                Clark testified
    that, pursuant to instructions given to him by Hodgkiss, he gave
    both drugs and records of drug sales to Thomas for delivery to
    Hodgkiss.      Moreover, Clark stated that he delivered controlled
    substances to Thomas on several occasions, and Hodgkiss assigned a
    code number to Thomas to facilitate the distribution of narcotics.8
    As with Gregg, we find that this evidence is sufficient to support
    Thomas's    conviction     for   conspiring    to   possess     a       controlled
    substance with intent to distribute.

    Sanchez contends that the evidence was insufficient to support

    must   prove   that   Sanchez    (1)    knowingly   conducted       a   financial
    8
    Thomas further argues that the government did not establish the
    identity of "07" because the government's "entire case was based on
    circumstantial evidence."     However, the government may use circumstantial
    evidence to establish the identity of a conspirator. See 
    Hernandez-Palacios, 838 F.2d at 1348
    (allowing the jury to infer that a defendant voluntarily joined a
    conspiracy from circumstantial evidence). Moreover, Clark testified that Thomas
    was "07" and Curtis testified that he delivered cocaine to Thomas on a regular
    basis. Thus, the evidence supports the jury's finding that Thomas was "07."

    113 S. Ct. 185
    , 
    121 L. Ed. 2d 129
    (1992).
    Sanchez argues that the evidence supporting his conviction is
    insufficient because it consists only of "government agents piecing
    together some written materials seized during drug raids which
    materials purportedly referenced [Sanchez] selling marijuana to
    someone unknown in the Hodgkiss organization."            We disagree.
    Clark testified that Sanchez, whose code number was "06,"
    delivered ten to fifteen pound quantities of marijuana to Clark
    "more than once."      Clark stated that these transactions would be
    reflected in the drug ledgers seized from his residence.              Officer
    Philip Steen testified that Clark's drug ledgers showed that Clark
    received fifteen pounds of marijuana from and paid $8,800 to
    Sanchez in March 1988.         Steen also stated that a similar sale
    occurred in April 1988 and that Sanchez was paid with money derived
    from drug sales.     As Clark was a member of the Hodgkiss conspiracy
    and the drug ledgers reflected the movement of drug proceeds from
    Clark to Sanchez, the evidence supports the jury's conclusion that
    Sanchez was guilty of money laundering.
    9
    A "financial transaction" is defined as "the movement of funds by
    wire or other means or . . . one or more monetary instruments" that "in any way
    or degree affects interstate or foreign commerce." 18 U.S.C. § 1956(c)(4).

    a
    Hodgkiss first argues that the evidence is insufficient to
    support his conviction for engaging in a CCE, in violation of 21
    U.S.C. § 848, because he did not organize, supervise, or otherwise
    manage five participants in his drug-trafficking conspiracy.10
    Hodgkiss, however, admits in his brief that he supervised three
    persons)) Aaron Clark, Robbie Curtis, and Gina Raven, Hodgkiss's
    girlfriend.11     Thus, the question before us is whether the evidence
    supports   a    finding   that   Hodgkiss     supervised    two   additional
    participants in the conspiracy.
    Edward Crawford, who has a doctorate in chemistry, testified
    that, for the sum of $25,000, he manufactured methamphetamine for
    Hodgkiss   and,    at   Hodgkiss's   direction,     instructed        two   other
    persons))"Jake" and Patrick Palmer))"in the art and science of
    manufacturing methamphetamine."           Crawford, Jake, and Palmer used
    chemicals obtained from Wesley Schneider to produce approximately
    10
    Section 848(c) provides that a person engages in a CCE if:
    (1) he violates any provision of [title 21] the punishment for which
    is a felony, and
    (2) such violation is part of a continuing series of violations of
    [title 21]))
    (A) which are undertaken by such person in concert with
    five or more other persons with respect to whom such
    person occupies a position of organizer, a supervisory
    position, or any other position of management, and
    (B) from which such person obtains substantial income or
    resources.

    Hodgkiss conceded at oral argument that he "probably" supervised a
    fourth person))Edward Crawford.

    twenty-four     pounds   of   methamphetamine      at   a   "meth   lab"     near
    Smithville, Texas.        Thus, the jury reasonably could infer from
    Crawford's testimony that Hodgkiss directed Crawford, Jake, and
    Palmer.12    Consequently, examining the evidence in the light most
    favorable to the government and giving the government the benefit
    of all reasonable inferences and credibility choices, we find that
    Hodgkiss managed at least five persons within the meaning of the
    statute.13
    b
    Hodgkiss also appeals his conviction for using or carrying a
    machine gun in relation to a drug trafficking offense, in violation
    of 18 U.S.C. § 924(c)(1).14           Hodgkiss argues that the firearm
    12
    Moreover, Palmer testified that Hodgkiss directed him to find a
    suitable location for a methamphetamine lab. Palmer then found the Smithville
    site, leased it in his own name with his own funds, and subsequently was
    reimbursed by John Rogala and Hodgkiss. After Crawford and Palmer manufactured
    one batch of methamphetamine, Hodgkiss instructed Palmer to place the remaining
    chemicals and lab equipment in storage.
    13
    Because we find that Hodgkiss organized, supervised, or managed
    Crawford and Palmer, we need not discuss whether Hodgkiss managed anyone else.
    However, we note that substantial evidence indicates that Hodgkiss likely managed
    several other persons at various times during the conspiracy's existence. See
    United States v. Phillips, 
    664 F.2d 971

    This section provides that
    [w]hoever, during and in relation to any crime of violence or drug
    trafficking crime . . . for which he may be prosecuted in a court of
    the United States, uses or carries a firearm, shall, in addition to
    the punishment provided for such crime of violence or drug
    trafficking crime, be sentenced . . . if the firearm is a machine
    gun . . . to imprisonment for thirty years.
    18 U.S.C. § 924(c)(1). "The term `machinegun' means any weapon which shoots, is
    designed to shoot, or can be readily restored to shoot, automatically more than
    one shot, without manual reloading, by a single function of the trigger." 26
    U.S.C. § 5845(b).
    -16-
    alleged by the government to be a machine gun actually was not such
    a weapon, that he did not "use or carry" the machine gun within the
    meaning of the statute, and that the district court erred in not
    granting a judgment of acquittal on the machine gun count.                    We
    disagree with all three contentions.
    (i)
    Hodgkiss initially argues that the AR-15 rifle found in his
    house by government agents was not a machine gun within the meaning
    of § 924(c)(1).     However, two expert witnesses))Bureau of Alcohol,
    Tobacco,     and    Firearms    agents        Davy   Aguilera    and   Geoffrey
    Descheemaeker))testified that the weapon had been altered to fire
    as a machine gun.      Thus, the evidence sufficiently supported the
    jury's conclusion that the weapon at issue was a machine gun.15               See
    
    Greenwood, 974 F.2d at 1458
        ("Assessing     the    credibility   of
    witnesses . . . is the exclusive province of the jury.").
    (ii)
    Hodgkiss next contends that he did not "use or carry" the
    firearm within the meaning of the statute because the machine gun
    was unloaded and stored in a zippered gun bag in a second-floor
    closet.    The presence of firearms at the home of a defendant where
    drugs, money, and ammunition are also found, however, is sufficient
    to establish the "use" of a firearm as an integral part of a drug-
    trafficking crime in violation of § 924(c).             See United States v.
    15
    Interestingly, Hodgkiss's attorney conceded during closing argument
    that the weapon was a machine gun: "I started out trying to downplay the fact
    that it was a machine gun. But after [Descheemaeker] got on, I just))he just
    backed me down. I))it's a machine gun, I give up."

    amount of methamphetamine, and over $20,000 in cash.           Don Howell,
    the stepfather of Hodgkiss's girlfriend, Gina Raven, testified that
    Hodgkiss on one occasion stated that he needed the weapon for
    protection because of "his line of business."16         See United States
    v. Martinez, 
    808 F.2d 1050
    , 1057 (5th Cir.) ("Firearms are `tools

    ,

    (1987).
    Based upon the record evidence, the jury was entitled to conclude
    based that Hodgkiss used the machine gun in relation to a drug-
    trafficking offense.       See, e.g., United States v. Capote-Capote,
    
    946 F.2d 1100
    , 1104 (5th Cir. 1991) (machine gun found with a

    (unloaded shotgun in gun rack of vehicle containing marijuana
    violated § 924(c) even though no shells were found in the vehicle).
    (iii)
    Hodgkiss finally contends that the district erred in denying
    his post-trial motion for a judgment of acquittal on the machine
    gun count, which defined the predicate drug trafficking crime
    required by § 924(c) to be the conspiracy alleged in count two of
    the indictment.       Hodgkiss argues that because he was acquitted of
    the conspiracy upon which the § 924(c) violation was predicated, he
    could not have been guilty of a § 924(c) violation.17
    Hodgkiss misinterprets the requirements of § 924(c). "[T]here
    is   no   statutory     requirement     that   the    government   secure   an
    17
    Although the jury found Hodgkiss guilty of the conspiracy alleged in
    count two, the district court entered a judgment of acquittal on that count
    because the jury also found Hodgkiss guilty of engaging in a continuing criminal
    enterprise, of which conspiracy is a lesser-included offense. See 
    Devine, 934 F.2d at 1342
    (noting that "a § 846 conspiracy is a lesser-included offense of a
    § 848 continuing criminal enterprise").

    underlying drug-trafficking conviction as a predicate for invoking
    section 924(c)(1)."    United States v. Munoz-Fabela, 
    896 F.2d 908
    ,
    909 (5th Cir.), cert. denied, 
    498 U.S. 824
    , 
    111 S. Ct. 76
    , 112 L.
    Ed. 2d 49 (1990).     Instead, "it is only the fact of the offense,
    and not a conviction, that is needed to establish the required
    predicate."   
    Id. at 911;
      see also United States v. Ruiz, 
    986 F.2d 905
    , 911 (5th Cir.) (acquittal on the predicate count does not
    preclude a conviction under § 924(c) if a reasonable jury could
    have found the defendant guilty of the predicate act), cert.

    114 S. Ct. 145
    , 
    126 L. Ed. 2d 107
    (1993).
    Thus, the jury's finding that Hodgkiss engaged in a conspiracy to
    distribute illegal drugs qualifies as a drug-trafficking offense
    under § 924(c), and is more than sufficient to support Hodgkiss's
    conviction.    Accordingly,   the   district   court   did   not    err   in
    refusing to enter a judgment of acquittal.
    C
    Sanchez and Hodgkiss contend that the district court erred in
    denying their motions for severance under Fed. R. Crim. P. 14.
    Sanchez contends that he was entitled to a severance because he had
    only a minimal involvement in the conspiracy, the jury was "simply
    overwhelmed" by the volume of evidence, and evidence admissible
    against other defendants was inadmissible as to him.               Hodgkiss
    argues that he was entitled to severance because evidence was
    admissible against other defendants but inadmissible against him
    -20-
    and his defense strategy conflicted with that of at least one of
    his co-defendants.18
    Denial of a motion for severance is reviewable only for an
    abuse of discretion.      Zafiro v. United States, ___ U.S. ___, 113 S.
    Ct. 933, 939,

    against which the trial court was unable to afford protection."
    
    Arzola-Amaya, 867 F.2d at 1516
    .                 "The rule, rather than the
    exception, is that persons indicted together should be tried
    together, especially in conspiracy cases."                     United States v.

    114 S.    Ct.   266,   126   L.   Ed.    2d    218   (1993).     Accordingly,   a
    quantitative disparity in the evidence "is clearly insufficient in
    itself to justify severance." United States v. Harrelson, 
    754 F.2d 1153
    , 1175 (5th Cir.), cert. denied, 
    474 U.S. 1034
    , 
    106 S. Ct. 599
    ,
    
    88 L. Ed. 2d 578
    (1985).            Moreover, "the mere presence of a
    spillover effect does not ordinarily warrant severance."                 United
    States v. Sparks, 
    2 F.3d 574
    , 583 (5th Cir. 1993).                     Finally,
    18
    Sanchez and Hodgkiss further allege that the indictment incorrectly
    charged a single conspiracy, thus demonstrating that joinder was initially
    incorrect under Fed. R. Crim. P. 8(b). In such cases, the defendants, to obtain
    a reversal of their convictions, need only establish that the misjoinder resulted
    in "actual prejudice." United States v. Lane, 
    474 U.S. 438
    , 449, 
    106 S. Ct. 725
    ,
    732, 
    88 L. Ed. 2d 814
    (1986). However, we already have found that the evidence
    supported the jury's verdict that a single conspiracy existed. See part 
    II.A. supra
    . Consequently, the Lane test is inapplicable. See also United States v.
    Piaget, 
    915 F.2d 138
    , 142 (5th Cir. 1990) (stating that Rule 8(b) "is to be
    broadly construed in favor of initial joinder").
    -21-
    severance is not required merely because co-defendants present
    mutually antagonistic defenses:          "Rule 14 leaves the determination
    of risk of prejudice and any remedy that may be necessary to the
    sound discretion of the district court."              
    Zafiro, 113 S. Ct. at 938-39
    .
    In this case, the government offered sufficient evidence
    demonstrating that Sanchez and Hodgkiss were guilty of the crimes
    charged.      See parts II.B.4 and 
    .5 supra
    .          Moreover, even if some
    risk of prejudice existed, the district court properly instructed
    the jury to limit evidence to the appropriate defendant,19 and
    "`juries are presumed to follow their instructions.'"              
    Zafiro, 113 S. Ct. at 939
    (quoting Richardson v. Marsh, 
    481 U.S. 200
    , 209, 
    107 S. Ct. 1702
    , 1708, 
    95 L. Ed. 2d 176
    (1987)).            Sanchez and Hodgkiss
    provide no sound reason for departing from this principle. Because
    Sanchez and Hodgkiss did not suffer compelling prejudice against
    which the district court was unable to afford protection, the
    district court did not abuse its discretion in refusing to sever
    their cases.
    19
    In addition to the multiple conspiracy instruction, see 
    note 4 supra
    ,
    the district court gave the following instruction:
    In determining whether a Defendant was a member of the alleged
    conspiracy, . . . you should consider only the evidence, if any,
    pertaining to his own acts and statements. He is not responsible
    for the acts or declarations of other alleged participants until it
    is established beyond a reasonable doubt first that a conspiracy
    existed, and second, that the Defendant was one of the members.
    The district court also instructed the jury that the defendants were not "on
    trial for any act, conduct or offense or offenses not alleged in the superseding
    indictment."

    D
    Sanchez and Hodgkiss next contend that the district court's
    denial of their requests for production of notes prepared by
    federal agents who debriefed several plea-bargaining defendants
    violated both the Jencks Act, 18 U.S.C. § 3500,20 and the Supreme
    Court's holding in Brady v. Maryland, 
    373 U.S. 83
    , 87, 
    83 S. Ct. 1194
    , 1196-97, 
    10 L. Ed. 2d 215
    (1963).21                 The government contends
    that        the   debriefing    notes    are    neither     Jencks   Act    nor   Brady
    material.
    Under the Jencks Act, a "statement" is (1) a written statement
    signed or otherwise adopted or approved by the witness, or (2) a
    "substantially verbatim recital" of an oral statement made by the
    witness.          18 U.S.C. § 3500;     United States v. Pierce, 
    893 F.2d 669
    ,
    675 (5th Cir. 1990).              An agent's interview notes thus are not
    "statements" of the witnesses interviewed unless the witnesses
    "signed, read, or heard the entire document read."                         
    Pierce, 893 F.2d at 675

    This section provides in relevant part:
    (b) After a witness called by the United States has testified
    on direct examination, the court shall, on motion of the defendant,
    order the United States to produce any statement (as hereinafter
    defined) of the witness in the possession of the United States which
    relates to the subject matter as to which the witness has testified.
    If the entire contents of any such statement relate to the subject
    matter of the testimony of the witness, the court shall order it to
    be delivered directly to the defendant for his examination and use.

    In Brady, the Supreme Court held that "the suppression by the
    prosecution of evidence favorable to an accused upon request violates due process
    where the evidence is material either to guilt or punishment, irrespective of the
    good faith or bad faith of the 
    prosecution." 373 U.S. at 87

    each of the government witnesses, they were unable to produce any
    evidence that one of these three conditions was met. See 
    id. Similarly, there
    is no evidence that any portion of the notes was
    a substantially verbatim transcription of the witness's statements.
    Thus, the notes are not discoverable under the Jencks Act as
    statements of the plea-bargaining defendants.22           United States v.
    Mora, 
    994 F.2d 1129
    , 1138 (5th Cir.), cert. denied, ___ U.S. ___,

    The defendants also contend that the notes constitute Brady
    material    because   they   contain   either   exculpatory    evidence    or
    evidence useful for impeachment purposes.            Prior to trial, the
    defendants requested from the government any Brady evidence.              The
    district court denied their motions as moot in light of the
    government's assurances that all Jencks and Brady material would be
    produced.    During trial, however, the defendants discovered that
    the government failed to produce the notes made by agents during
    debriefing sessions with the plea-bargaining defendants.                  The
    government contends that the debriefing notes did not have to be
    produced because they contained no exculpatory or otherwise useful
    information.     The record is unclear as to whether the district

    Although the district court addressed the issue whether the notes

    exact     findings   of    the     district       court    regarding    the   material
    reviewed in camera by the court.24
    Accordingly,         rather    than    determine       ourselves     whether   the
    government should have produced the notes pursuant to the Brady
    doctrine))i.e., whether the notes contain evidence material either
    to guilt or      punishment))we        remand       this    matter   to   permit    the
    district court to make such a determination in the first instance.

    court concludes that the notes need not have been produced, it
    should supplement the record with the notes and with sufficiently
    detailed findings to enable us to review the decision.                     Welch, 810
    23
    The government contends that the district court                     reviewed
    all debriefing notes prepared by government agents. The                       record,
    however, indicates that the government produced only two                      sets of
    notes))one for the debriefing sessions of Alan Gardner and                    one for
    witness Don Howell. Moreover, only the notes related to                       Gardner
    are included in the record on appeal.
    24
    The district court reviewed in camera the notes from
    Gardner's debriefing sessions. The court then denied Maxwell's
    motion for production of the notes, thereby implying that the notes
    contained no Brady material. However, in denying Maxwell's motion,
    the court remarked that "to say there is no exculpatory or Brady
    material in that would be to engage in severe overstatement."

    misstated his conclusion, the exact import of its ruling is unclear

    reasonable probability that, had the evidence been disclosed to the
    defense, the result of the proceeding would have been different."

    Maxwell contends that the trial judge should have given to the
    jury the "buyer-seller" instruction that he requested.                    This
    25
    Because we remand this matter the district court, we need not address
    the defendants' additional contention that the notes constitute Jencks Act
    statements of the testifying agents. Notes taken by an agent during witness
    interviews can constitute statements of the agent under the Jencks Act, even if
    the notes do not constitute statements of the witnesses. See United States v.
    Sink, 
    586 F.2d 1041
    , 1051 (5th Cir. 1978) (finding an agent's report, prepared
    from his notes and recollections from witness interviews, to be a statement of

    instruction, apparently based on United States v. Hughes,

    , 
    108 S. Ct. 170
    , 
    98 L. Ed. 2d 124
    (1987), directed the jury to acquit Maxwell if they
    believed that he received cocaine "for his own personal use and not
    to facilitate the conspiracy or because he was a member of the
    conspiracy."     The government argues that the essence of Maxwell's
    proposed   instruction    was   substantially    covered    by    the   charge
    actually given to the jury.      We agree.
    The district court's refusal to give a requested instruction
    is reviewed for an abuse of discretion.         United States v. Sellers,
    
    926 F.2d 410
    , 414 (5th Cir. 1991).        Under this standard of review,
    the   district    court   has   "substantial     latitude    in    tailoring
    instructions so long as they fairly and adequately cover the issues
    presented," United States v. Pool, 
    660 F.2d 547
    , 558 (5th Cir. Unit
    B Nov. 1981), and is "under no obligation to give a requested
    instruction that misstates the law, is argumentative, or has been
    adequately covered by other instructions."             United States v.
    L'Hoste, 
    609 F.2d 796
    , 805 (5th Cir.), cert. denied,

    ,
    
    101 S. Ct. 104
    , 
    66 L. Ed. 2d 39
    (1980).
    "While it is true that a buyer-seller relationship, without
    more, will not prove a conspiracy, evidence of such activity goes
    to whether the defendant intended to join in the conspiracy or
    whether his or her participation was more limited in nature."
    United States v. Maserati, 
    1 F.3d 330
    , 336 (5th Cir. 1993).
    Accordingly, the drug conspiracy laws focus exclusively on the
    -27-
    question "whether the participants knowingly joined an agreement to
    distribute drugs in violation of the law."           
    Id. Therefore, if
    the
    evidence demonstrates only that someone purchased drugs from the
    conspiracy and did not agree to join it, "the elements necessary to
    prove a conspiracy would be lacking, and a not guilty verdict would
    result."      
    Id. In this
    case, the district court, using our Pattern
    Jury   Charge,      accurately   instructed    the   jury    on    the     law   of
    conspiracy, and the jury found Maxwell guilty of conspiring to
    distribute drugs.       Thus, the jury, by rendering a guilty verdict,
    specifically found that Maxwell agreed to join the conspiracy.                   We
    therefore find that Maxwell's theory was adequately covered by the
    instructions, and the district court did not abuse its discretion
    in refusing to give the requested instruction.             See id.;

    Gregg argues that the district court incorrectly denied his
    motion   to    suppress   evidence    seized   during      the    search    of   an
    automobile he was driving.       Gregg contends that the police officer
    who searched the vehicle lacked probable cause to do so, thus

    Hodgkiss argues that the district court erred in refusing to instruct
    the jury that they had to unanimously agree on the identity of the five
    individuals whom Hodgkiss managed as part of the CCE. However, as Hodgkiss noted
    at oral argument, the jury need not unanimously agree on the identities of the
    five individuals. United States v. Linn,

    , 
    111 S. Ct. 43

    (1990). The district
    court thus did not abuse its discretion in rejecting the proposed instruction.

    making the seized evidence the fruit of an illegal search.                     The
    government argues that the officer had probable cause to search the
    vehicle and that Gregg abandoned the bag in which the officer found
    the contraband, thereby barring Gregg from challenging the legality
    of the search.
    "In   reviewing   a    district   court's   ruling     on   a    motion    to
    suppress evidence based on testimony at a suppression hearing, we
    must accept the district court's factual findings unless they are
    clearly erroneous or are influenced by an incorrect view of the
    law."    United States v. Garcia, 
    849 F.2d 917
    , 917 n.1 (5th Cir.
    1988).     "Further, we must view the evidence in the light most
    favorable to the party that prevailed below."             
    Id. However, we
    review de novo the ultimate conclusion drawn from the district
    court's factual finding.      United States v. Diaz, 
    977 F.2d 163
    , 164
    (5th Cir. 1992).
    The Fourth Amendment provides that "the right of the people to
    be secure in their persons, houses, papers, and effect, against
    unreasonable     searches    and   seizures   shall   not     be      violated."
    Evidence obtained by the government in violation of a defendant's
    Fourth Amendment rights may not be used to prove the defendant's
    guilt at trial.     Weeks v. United States, 
    232 U.S. 383
    , 398, 34 S.
    Ct. 341, 346,

    ,
    
    88 S. Ct. 1868
    , 
    20 L. Ed. 2d 889
    (1968), the Supreme Court stated
    that where there is a reasonable and articulable suspicion that a
    person has committed a crime, a limited search and seizure is not
    -29-
    unreasonable.       Thus,    if   the   detaining   officer    can   "point   to
    specific and articulable facts which, taken together with rational
    inferences from those facts, reasonably warrant [the search and
    seizure]," the intrusion is lawful.            
    Id. at 21,
    88 S. Ct. at 1880.
    Mississippi Deputy Sheriff Billy Collins initially stopped the
    vehicle Gregg was driving because the automobile was weaving
    between lanes.     Thus, the initial detention was proper under Terry
    because Collins had reasonable and articulable facts that warranted
    the intrusion))Gregg had violated traffic laws.             United States v.
    Shabazz, 
    993 F.2d 431
    , 435 (5th Cir. 1993);            United States v. Kye
    Soo Lee, 
    898 F.2d 1034
    , 1040 (5th Cir. 1990).                 After Gregg was
    initially detained, however, Collins was presented with a second
    set of circumstances that, in our opinion, justified Gregg's
    continued detention.        This second set of facts included the smell
    of marijuana emanating both from Gregg's person and from the
    vehicle, Gregg's deception regarding whether he had ever been
    arrested,27 and that Gregg was not the registered owner of the
    vehicle. These factors gave Collins probable cause to believe that
    the vehicle contained contraband, thus giving him the right to
    search the vehicle.       See United States v. Ryles, 
    988 F.2d 13
    , 14
    n.2 (5th Cir.) (noting that an officer's "smelling marijuana
    afford[s] probable cause to engage in a warrantless search" of a

    Collins asked Gregg whether he had ever been arrested, and Gregg replied that he
    had not. See

    (finding that an officer may lawfully ask
    questions of traffic-stop detainees while waiting for the results of computer

    previously had been arrested in Florida for a drug-related offense.

    Gregg nevertheless contends that because Collins did not have
    probable cause to search the camera bag in which Collins found
    marijuana and cocaine, the evidence should be suppressed. However,
    Gregg ignores the fact that he abandoned the camera bag.                 When
    Collins asked Gregg who owned the bag, Gregg shrugged his shoulders
    and stated that he did not know.28         Gregg thus abandoned the bag,
    allowing Collins to examine its contents.

    abandonment is not a product of improper police conduct, the
    defendant cannot challenge the subsequent search of the bag."
    
    Piaget, 915 F.2d at 140
    .        As Collins had probable cause both to
    stop Gregg's vehicle and to search it, Gregg could not have
    abandoned     the   bag   as   result    of   improper    police    conduct.
    Consequently, we find no error in the district court's denial of
    Gregg's motion to suppress.
    28
    Gregg appears to challenge the district court's decision to credit
    the testimony of officer Collins over that of Gregg. However, we must give due
    deference to the credibility determinations of the district court, who has the
    opportunity to observe the demeanor of witnesses. See Amadeo v. Zant, 
    486 U.S. 214
    , 
    108 S. Ct. 1771

    B
    Gregg    further    argues       that     the    prosecutor     engaged    in
    prosecutorial misconduct by improperly bolstering the credibility
    of government witnesses and expressing his personal opinion about
    the credibility of one government witness during closing arguments.
    The government contends that the prosecutor simply responded,
    albeit in a "rhetorically excessive" fashion, to defense counsel's
    attack on the credibility of the witnesses.
    Thomas did not object to the prosecutor's statements that he
    now contends requires reversal of his conviction. Consequently, we
    must consider whether the statements were improper and, if so,
    whether they amounted to plain error under Fed. R. Crim. P. 52(b).29
    United States v. Hernandez, 
    891 F.2d 521
    , 526 (5th Cir. 1989),

    , 
    110 S. Ct. 1935
    , 
    109 L. Ed. 2d 298
    (1990).    We must review the allegedly improper argument "in light
    of the argument to which it responded."               United States v. Canales,
    
    744 F.2d 413
    , 424 (5th Cir. 1984).             Thus, the government "may even
    present   what    amounts    to   be    a     bolstering   argument    if   it   is
    specifically done in rebuttal to assertions made by defense counsel
    in order to remove any stigma cast upon [the prosecutor] or his
    witnesses."      United States v. Dorr, 
    636 F.2d 117
    , 120 (5th Cir.
    1981).

    Fed. R. Crim. P. 52(b) provides that "[p]lain errors or defects
    affecting substantial rights may be noticed although they were not brought to the
    attention of the court."
    -32-
    During closing arguments, defense counsel contended that the
    plea bargain agreements between many of the government witnesses
    and the prosecution invited the witnesses to perjure themselves so
    as to procure lesser sentences.                Specifically, defense counsel
    argued   that   Clark,   who     testified      that   he   was   afraid   of   the
    prosecutor,     lied   because    of     the    "Draconian    thumb"     that   the
    government placed on his neck.30               The prosecutor, in rebuttal,
    responded in kind:
    Perhaps I should turn to Aaron Clark and why he is afraid
    of me.    And you know, Ladies and Gentlemen, they're
    right, Aaron Clark was afraid of me, and I hope he was
    afraid of me. I hope he remains afraid of me, because he
    did something that is unforgivable, he lied under oath to
    you; that isn't tolerable.
    As Clark admitted under oath that he lied to the jury with regard
    to whether he was an employee of Hodgkiss or an "independent
    contractor," the prosecutor was entitled to comment before the jury
    on   Clark's    testimony.       Moreover,      the    prosecutor's     statements
    directly   responded     to    defense    counsel's      attacks   on    both   the
    prosecutor and government witnesses who testified pursuant to plea
    agreements. Accordingly, the comments were not improper and do not
    constitute plain error under Rule 52(b).
    30
    Defense counsel also argued that the government first determined what
    it believed to be the truth and then "put[] the thumbscrew on the witness" to
    agree with the government's version.

    Thomas contends that he was denied his Sixth Amendment right
    to effective assistance of counsel because his trial counsel failed
    to make various objections at trial and also failed to move for a
    judgment of acquittal following the close of the evidence. Thomas,
    however, failed to present this issue to the district court.31
    "The   general    rule    in   this    circuit    is    that     a   claim   of
    ineffective assistance of counsel cannot be resolved on direct
    appeal when the claim has not been before the district court since
    no opportunity existed to develop the record on the merits of the
    allegation."     United States v. Higdon, 
    832 F.2d 312
    , 313-14 (5th
    Cir. 1987), cert. denied,

    , 
    108 S. Ct. 1051
    , 
    98 L. Ed. 2d
    1013 (1988).     If the defendant fails to raise the claim before
    the district court, we will reach the merits of the claim only if
    the record is well-developed.         
    Id. This is
    not such a case.         As in
    United States v. Freeze, 
    707 F.2d 132
    , 139 (5th Cir. 1983),
    [w]hile we might be able to determine, on the basis of
    the trial record, whether the defendant had been deprived
    of effective assistance of counsel with regard to the
    failure to make a motion for judgment of acquittal, we
    can only speculate about why defense counsel made no
    objections to the evidence. Accordingly, we decline to
    reach the merits of the defendant's ineffective
    assistance claim.
    Thomas,   of   course,    may    raise      this    issue    in   an   appropriate
    proceeding under 28 U.S.C. § 2255.           Id.;    see also United States v.
    31
    Although Thomas in his brief cited two instances where he raised his
    claim before the district court, we have reviewed the record without finding any
    indication that the district court was made aware of Thomas's allegation that his
    trial counsel was constitutionally ineffective.

    Sentencing
    The defendants appeal the sentences imposed by the district
    court under the Sentencing Guidelines. We will affirm any sentence
    imposed by the district court "so long as it results from a correct
    application of the guidelines to factual findings which are not
    clearly erroneous."   United States v. Sarasti, 
    869 F.2d 805
    , 806
    (5th Cir. 1989).   "A factual finding is not clearly erroneous as
    long as it is plausible in light of the record as a whole."   United
    States v. Sanders, 
    942 F.2d 894
    , 897 (5th Cir. 1991).
    A
    The defendants initially argue that the district court erred
    by calculating their sentences on the basis of drug purchases and
    sales not only by themselves, but also by other co-conspirators.32
    32
    The presentence investigative report ("PSR") found that
    the Hodgkiss conspiracy distributed over 150 kilograms of cocaine
    or its equivalent.    The PSRs additionally found that Hodgkiss,
    Thomas, Gregg, and Sanchez each should be held responsible for that
    amount.    The defendants objected to these findings during
    sentencing. The district court, however, overruled the objections
    and adopted the PSRs's findings. Hodgkiss, Gregg, and Sanchez now
    argue that the district court did not comply with Fed. R. Crim. P.
    32(c)(3)(D) because it failed to specifically find that they knew
    or reasonably should have foreseen that the conspiracy would
    involve over 150 kilograms of cocaine. However, an oral rejection
    of a defendant's objection to a PSR satisfies the rule. United
    States v. Sparks, 
    2 F.3d 574
    , 588 (5th Cir. 1993); United States
    v. Stouffer, 
    986 F.2d 916
    , 927 (5th Cir.), cert. denied, ___ U.S.
    ___, 
    114 S. Ct. 115
    , 
    126 L. Ed. 2d 80
    (1993); United States v.
    Lghodaro, 
    967 F.2d 1028
    , 1030 (5th Cir. 1992).
    -36-
    They contend that because they could not have reasonably foreseen
    that the Hodgkiss conspiracy would involve such a large quantity of
    drugs, the district court should not have taken into account the
    entire     amount   of   drugs   attributed     to    the    conspiracy      when
    determining their respective base offense levels.33
    "A district court's findings about the quantity of drugs
    implicated by the crime are factual findings reviewed under the
    `clearly erroneous' standard."         United States v. Rivera, 
    898 F.2d 442
    , 445 (5th Cir, 1990).        Applying this standard, we uphold the
    district     court's     determinations     that     the    defendants    could
    reasonably foresee the amount of cocaine for which they were held
    responsible.
    1
    Hodgkiss contends that the evidence does not support the
    district court's finding that he knew or should have reasonably
    foreseen that the conspiracy he founded distributed over 150
    kilograms of cocaine or its equivalent.               However, drug ledgers
    seized from Hodgkiss's residence indicate that the conspiracy was
    responsible for distributing approximately 56 kilograms of cocaine
    33
    A defendant's base offense level is determined on the basis of
    all acts and omissions committed or aided and abetted by the
    defendant, or for which the defendant would be otherwise
    accountable, that occurred during the commission of the offense of
    conviction, in preparation for that offense, or in the course of
    attempting to avoid detection or responsibility for that offense, or
    that otherwise were in furtherance of that offense.
    U.S.S.G. § 1B1.3(a)(1). "Conduct `for which the defendant would otherwise be
    accountable' . . . includes conduct of others in furtherance of the execution of
    the jointly-undertaken criminal activity that was reasonably foreseeable by the
    defendant." U.S.S.G. § 1B1.3, comment. (n.1).
    -37-
    from January 27, 1988 to July 7, 1989.            As this period constitutes
    approximately one-third of the conspiracy's life-span, the district
    court, in light of the record evidence, reasonably could have
    inferred that the conspiracy was responsible for distributing in
    excess of 150 kilograms of cocaine during its existence. Moreover,
    testimony presented by the government and evidence contained in the
    PSR, including information obtained from other defendants, also
    established that the conspiracy distributed in excess of 150
    kilograms of cocaine.34     Consequently, the district court's finding
    that Hodgkiss, who organized and retained control over every aspect
    of the conspiracy, knew or should have reasonably foreseen the
    amount of controlled substances distributed by the conspiracy is
    not clearly erroneous.
    2
    Gregg also contends that the district court improperly held
    him accountable for an excessive quantity of drugs.                 However,
    Gregg, pursuant to a carefully devised plan, delivered multiple
    kilograms of cocaine to Richard Townsen for John Rogala that Rogala
    later sold to Hodgkiss.      Moreover, Norman Allanson testified that
    Gregg transported, or attempted to transport, twenty-one kilograms
    of cocaine from Florida to Texas for Rogala, who also joined forces
    with Hodgkiss to manufacture a large quantity of methamphetamine.
    Furthermore,    the   PSR   indicates      that    Gregg   was   involved   in
    34
    We note that government agents repeatedly classified this as
    "conservative" estimate of the entire amount of illegal substances distributed
    during the life of the conspiracy.
    -38-
    transporting massive quantities of cocaine for Allanson and Rogala.
    See also part 
    II.B.2 supra
    .        "[A]n individual dealing in a sizable
    amount of controlled substances ordinarily will be presumed to
    recognize that the drug organization with which he deals extends
    beyond his universe of involvement."35 United States v. Thomas, 
    963 F.2d 63
    , 65 (5th Cir. 1992).         Thus, the district court's finding
    that Gregg     was   responsible    for   the   distribution    of   over   150
    kilograms of cocaine is not clearly erroneous.36
    35
    In this regard, we note that Gregg apparently was not a novice in
    matters related to the distribution of controlled substances. Ledgers seized
    from Gregg's residence indicated that, separate from the Hodgkiss conspiracy, he
    was responsible for drug sales of over $245,000 between 1987 and 1990.
    36
    Gregg argues that recent amendments to the commentaries
    and application notes for U.S.S.G. § 1B1.3 indicate that the
    district court erroneously held him accountable for a quantity of
    drugs not reasonably foreseeable to him. Illustration (c)(7) to
    application note 2 provides:
    Defendant R recruits Defendant S to distribute 500 grams
    of cocaine. Defendant S knows that Defendant R is the
    prime figure in a conspiracy involved in importing much
    larger quantities of cocaine. As long as Defendant S's
    agreement and conduct is limited to the distribution of
    the 500 grams, Defendant S is accountable only for that
    500 gram amount . . ., rather than the much larger
    quantity imported by Defendant R.
    In United States v. Maseratti, 
    1 F.3d 330
    , 340 (5th Cir. 1993), we
    cited this illustration when vacating the sentences of defendants
    convicted of conspiring to distribute drugs "who may [have been]
    involved in less than the entire conspiracy." Maseratti, however,
    is distinguishable from the present case because the evidence
    indicates that Gregg, like the other defendants, did not enter into
    an agreement involving limited conduct like that described in the
    illustration.   Instead, Gregg agreed to enter into an ongoing
    relationship with other co-conspirators involving not only the
    acquisition and distribution of drugs, but also protecting the
    conspiracy from detection using the relatively sophisticated code
    and delivery systems. Moreover, the evidence indicates that Gregg
    knew both that he was part of a larger conspiracy and that his
    actions helped to ensure))indeed, were necessary for))the success
    -39-
    3
    Thomas argues that the district court improperly held him
    accountable         for   the   entire   amount     of     controlled    substances
    distributed by the Hodgkiss conspiracy.                  Hodgkiss's drug ledgers
    indicated that between January 1988 and July 1989, Thomas))whom
    Hodgkiss assigned code number "07"))received in excess of two
    kilograms of cocaine and amphetamine from Hodgkiss. Moreover, both
    Curtis   and    Clark      identified     Thomas    as   someone    to    whom    they
    delivered narcotics on a regular basis for several years.                    Thomas
    also served as a conduit for the delivery of drug ledgers and drugs
    from Clark to Hodgkiss.           See also part 
    II.B.3 supra
    .           Accordingly,
    the district court's finding that Thomas knew or should have
    reasonably foreseen that the conspiracy of which he was a member
    would distribute in excess of 150 kilograms of cocaine is not
    clearly erroneous.
    4
    Sanchez contends that he could not reasonably foresee that the
    Hodgkiss conspiracy would distribute the amount of drugs for which
    the district court held him responsible.                   However, Sanchez))whom
    Hodgkiss    assigned       code   number   "06"))sold       large   quantities      of
    marijuana      to    Hodgkiss     on   three    separate    occasions.       On    two
    occasions, Sanchez received $8,800 in drug-related proceeds from
    Clark as payment for the marijuana.              Clark also identified Sanchez
    as one of Hodgkiss's distributors to whom Clark delivered cocaine
    of the conspiracy.
    -40-
    and   amphetamine   on   numerous     occasions.      Ledgers     seized    from
    Hodgkiss's residence indicated that from January 27, 1988 to July
    7, 1989, Sanchez received twenty-two ounces of cocaine and five
    ounces   of   amphetamine    from    Hodgkiss.      Moreover,     a   telephone
    scrambling device seized from Sanchez's residence matched a similar
    device found in possession of Hodgkiss.               See also part 
    II.B.4 supra
    . Consequently, the district court's finding that Sanchez knew
    or should have reasonably foreseen that his co-conspirators would
    be responsible for distributing in excess of 150 kilograms of
    cocaine is not clearly erroneous.
    5
    The district court ultimately held Maxwell responsible only
    for the distribution of between fifteen and fifty kilograms of
    cocaine or its equivalent.      This amount roughly corresponds to the
    amount of cocaine sold by Alan Gardner during the time that Gardner
    supplied both Hodgkiss and Maxwell with cocaine.              In 1988, Maxwell
    began purchasing on a regular basis multi-ounce quantities of uncut
    cocaine from Gardner.       Gardner's employee Charles Barton usually
    delivered the cocaine to Maxwell, and Gardner often "fronted"
    Maxwell the uncut cocaine.          Cf. U.S.S.G. § 2D1.1, comment. (n.8)
    (noting "the fact that a defendant is in possession of unusually
    pure narcotics may indicate a prominent role in the criminal
    enterprise and proximity to the source of the drugs. . . . [T]his
    factor   is   particularly   relevant       where   smaller    quantities    are
    involved.").    Maxwell also sold cocaine to Ronald McWilliams, who
    -41-
    at one time had been a supplier of cocaine to Maxwell.               See also
    part 
    II.B.1. supra
    .    The district court found from this evidence
    that Maxwell reasonably should have foreseen from this evidence
    both that the conspiracy with which he was involved extended beyond
    himself and that the conspiracy was distributing at least fifteen
    kilograms   of   cocaine.    Because    this    finding   is   not    clearly
    erroneous, we will uphold Maxwell's sentence.
    B
    Thomas and Hodgkiss argue that the district court erred in
    sentencing them under the amendments to the sentencing guidelines
    effective November 1, 1989, because the Hodgkiss conspiracy ended
    before that date. They contend that because the 1989 amendments to
    the guidelines increased the penalties to which they were subject,
    the district court violated the Ex Post Facto Clause of the
    Constitution by sentencing them under the amendments.
    "[A]n increase in sentence based on an amendment to the
    guidelines effective after the offense was committed `would be an
    obvious . . . violation' of the ex post facto clause in article 1
    of the United States Constitution."       United States v. Suarez, 
    911 F.2d 1016
    , 1021 (5th Cir. 1990) (quoting United States v. Woolford,
    
    896 F.2d 99
    , 102 n.4 (5th Cir. 1990)).         A conspiracy, however, "is
    a continuing offense.       So long as there is evidence that the
    conspiracy continued after the effective date of the [amendments to
    the] guidelines, the Ex Post Facto Clause is not violated." United

    Thomas    and   Hodgkiss      argue    that    no      evidence     exists
    demonstrating that any acts related to the conspiracy took place
    after November 1, 1989.        They do not, however, argue that they
    withdrew     from   the   conspiracy    by    taking       "affirmative       acts
    inconsistent with the object of the conspiracy and communicated in
    a   manner   reasonably    calculated   to   reach       other   conspirators."

    ___, 
    112 S. Ct. 1165
    , 
    117 L. Ed. 2d 412
    (1992).              If a conspirator
    fails to effectively withdraw from the conspiracy, he "will be
    sentenced under the [amendments to the] guidelines even if he
    himself did not commit an act in furtherance of the conspiracy
    after [November 1, 1989], or did not know of acts committed by
    other   co-conspirators     after    [November      1,    1989],    if   it    was
    foreseeable that the conspiracy would continue past the effective
    date of the [amendments]."       
    Devine, 934 F.2d at 1332
    .
    The district court determined that the defendants should be
    sentenced under the 1989 amendments because the evidence adduced
    both at trial and during sentencing indicated that the conspiracy
    did not cease until, at the earliest, the search of Hodgkiss's home
    in December 1989.         We regard this determination as a factual
    finding protected by the clearly erroneous standard of review. 
    Id. -43- After
    reviewing the record as a whole, we find that the district
    court's conclusion was not clearly erroneous.37 Moreover, the jury,
    as alleged in the indictment, found the defendants guilty of
    conspiring to distribute drugs from "on or about June 1, 1986 and
    continuing until December 15, 1989."            Consequently, the district
    court's use during sentencing of the amendments in effect at the
    time the conspiracy concluded did not violate the Ex Post Facto
    Clause.
    C
    Gregg contends that he was entitled to a downward adjustment
    under the sentencing guidelines for minimal or minor participation
    in the conspiracy.38      He argues that he was only slightly involved
    with the conspiracy and therefore is less culpable than the other
    conspirators.      Section 3B1.2, however, is designed to reduce a
    sentence only when a defendant is substantially less culpable than
    the    average   participant     in   the    offense.     United    States    v.
    Buenrostro, 
    868 F.2d 135
    , 138 (5th Cir. 1989), cert. denied, 
    495 U.S. 923
    , 
    110 S. Ct. 1957
    , 
    109 L. Ed. 2d 319
    (1990).              The district
    37
    For example, we note that Hodgkiss's drug ledgers indicate that at
    least one drug transaction occurred during December 1989. Moreover, Clark))whom
    Hodgkiss concedes was his employee))testified that his relationship with Hodgkiss
    did not end until December 1989.
    38
    U.S.S.G. § 3B1.2 provides:
    Based on the defendant's role in the offense, decrease the offense
    level as follows:
    (a) If the defendant was a minimal participant in any criminal
    activity, decrease by 4 levels.
    (b) If the defendant was a minor participant in any criminal
    activity, decrease by 2 levels.
    In cases falling in between (a) and (b), decrease by three levels.
    -44-
    court denied Gregg's request for a downward adjustment because
    Gregg was not substantially less culpable than the average co-
    conspirator. We agree that the record belies Gregg's argument that
    he was a minimal or minor participant in the Hodgkiss conspiracy.
    See parts II.B.2 and 
    VI.A.2 supra
    .             Consequently, we will not
    disturb the district court's finding that Gregg was not a minimal
    or minor participant.
    D
    Gregg argues he was entitled to a downward adjustment in his
    offense level because he accepted responsibility for his crimes.
    Under § 3E1.1(a) of the guidelines, "[i]f the defendant clearly
    demonstrates a recognition and affirmative acceptance of personal
    responsibility for his criminal conduct," a district court may
    reduce the defendant's offense level by two points.              However, the
    adjustment "is not intended to apply to a defendant who puts the
    government to its burden of proof at trial by denying the essential
    factual elements of guilt, is convicted, and only then admits guilt
    and expresses remorse."        U.S.S.G. § 3E1.1. comment. (n.2).            The
    district court found that Gregg did not fully accept responsibility
    for his crimes and refused to reduce the offense level.              We review
    this finding using the clearly erroneous standard.             United States
    v. Hardeman, 
    933 F.2d 278
    , 283 (5th Cir. 1991).39
    39
    We have not definitively determined what standard applies when
    reviewing a district court's refusal to credit a defendant's acceptance of
    responsibility.    Compare 
    Hardeman, 933 F.2d at 283
    (applying the clearly
    erroneous standard) with United States v. Thomas, 
    870 F.2d 174
    , 176 (5th Cir.
    1989) (applying the "without foundation" standard) and United States v. Brigman,
    
    953 F.2d 906
    , 909 (5th Cir.) (applying the "great deference" standard), cert.
    -45-
    While Gregg accepted responsibility for some acts, he did not
    demonstrate "sincere contrition" regarding the full extent of his
    criminal conduct.      United States v. Beard, 
    913 F.2d 193
    , 199 (5th
    Cir. 1990). Instead, Gregg both minimized his participation in the
    conspiracy even after he was found guilty and refused to discuss
    information contained in the drug ledgers seized from his home.
    See United States v. Windham, 
    991 F.2d 181
    , 183 (5th Cir.) (noting
    that a defendant is required under the pre-1992 guidelines to
    accept responsibility for all relevant criminal conduct to be
    eligible for a downward departure under § 3E1.1), cert. denied, ___

    919 F.2d 962
    , 968 (5th Cir. 1990) (same). Accordingly, the district court's
    finding that Gregg did not accept responsibility is not erroneous.
    E
    Gregg further contends that the district court miscalculated
    his criminal history category for sentencing purposes.40                  Gregg
    contends that the district court improperly considered hearsay
    evidence, supplied by a government agent, indicating that Gregg was
    involved in narcotics activity while on probation from a previous
    conviction.     However, a district court "may properly consider any

    ,

    three standards." United States v. Cartwright, ___ F.3d ___, slip op. at 893

    The guidelines direct the district court to "[a]dd 2 points [to the
    defendant's offense level] if the defendant committed the instant offense while

    rules     of     evidence     applicable       at    trial,   provided      that     the
    information has sufficient indicia of reliability to support its
    probable accuracy'" during sentencing.                    
    Alfaro, 919 F.2d at 964
    (quoting U.S.S.G. § 6A1.3(a)).
    Sworn testimony given by a government agent at a sentencing
    hearing generally bears sufficient indicia of reliability to be
    considered by the trial judge during sentencing.                      See 
    id. at 966
    (noting        that   a   PSR    generally      bears     sufficient       indicia    of
    reliability);         United States v. Cuellar-Flores, 
    891 F.2d 92
    , 93
    (5th Cir. 1989) (finding uncorroborated hearsay testimony provided
    by a probation agent to be sufficiently reliable).                    Merely because
    the agent's testimony was based on information obtained from one of
    Gregg's co-conspirators is not sufficient to bar the district court
    from considering it.            Consequently, the district court did not err
    by considering the agent's testimony when determining Gregg's
    criminal history category.
    F
    The      jury   found     Gregg   guilty      of   conspiring   to    possess    a
    controlled substance with intent to distribute, in violation of 21
    U.S.C. §§ 841(a)(1) and 846.             Section 841(b)(1)(A), which is the
    applicable sentencing provision, establishes one sentencing range
    for first-time offenders and another for repeat offenders.41                       Gregg
    41
    In cases where death or serious injury does not result from the use
    of an illegal substance, first-time offenders "shall be sentenced to a term of
    imprisonment which may not be less than 10 years or more than life" while repeat
    offenders must be sentenced to not "less than 20 years [or] more than life." 21
    -47-
    contends that the district court erred in sentencing him under the
    repeat-offender provision of the statute because the government
    failed to give timely notice pursuant to § 851(a)(1) of its intent
    to seek such enhancement.         The government responds that the notice
    provision of § 851(a)(1) does not apply to enhancement under the
    recidivist provisions of § 841(b).
    Section    851(a)(1)        requires      the   government   to    file    an
    information identifying the prior drug-related convictions upon
    which a defendant convicted of an offense under § 841 is to be
    given an enhanced sentence:
    No person who stands convicted of an offense under this
    part shall be sentenced to increased punishment by reason
    of one or more prior convictions, unless before trial, or
    before entry of a plea of guilty, the United States
    attorney files an information with the court (and serves
    a copy of such information on the person or counsel for
    the person) stating in writing the previous conviction to
    be relied upon. . . .
    Thus, the § 851(a)(1) notice requirement applies "to situations in
    which a convicted defendant's statutory minimum or maximum penalty
    is enhanced under [21 U.S.C § 841]."            United States v. Wallace, 
    895 F.2d 487
    , 490 (8th Cir. 1990);          see also United States v. Marshall,
    
    910 F.2d 1241
    , 1244-45 (5th Cir. 1990) ("the notice requirement
    applies to persons convicted of an offense under Title 21 when the
    Government    seeks      to   enhance   the    maximum   penalties     under   the
    recidivist provision of that statute"), cert. denied, 
    498 U.S. 1092
    , 
    111 S. Ct. 976
    , 
    112 L. Ed. 2d 1061

    904 F.2d 306
    , 309 (5th Cir. 1990) (same), cert. denied,

    , 
    111 S. Ct. 76
    5, 
    112 L. Ed. 2d 784
    (1991).           As a result,
    the government failed to comply with § 851(a) by filing the
    enhancement notice after trial.
    Because the government did not timely comply with § 851(a)(1),
    the district court did not have jurisdiction to enhance Gregg's
    sentence under the recidivist provisions of § 841(b).               United
    States v. Noland, 
    495 F.2d 529
    , 533 (5th Cir.), cert. denied,

    95 S. Ct. 228
    , 
    42 L. Ed. 2d 181
    (1974);        see also Suveges
    v. United States, ___ F.3d ___, 
    1993 WL 403091
    (1st Cir. Oct. 14,
    1993)     ("The    filing     of   such   an   informational    notice   is
    jurisdictional.");      United States v. Belanger, 
    970 F.2d 416
    , 417
    (7th Cir. 1992) ("Failure to file the notice prior to trial
    deprives the district court of jurisdiction to impose an enhanced
    sentence."); United States v. Novey, 
    922 F.2d 624
    , 627 (10th Cir.)
    (same), cert. denied, ___ U.S. ___, 
    111 S. Ct. 2861
    , 
    115 L. Ed. 2d 1028
    (1991).      Moreover,
    [e]ven when the defendant is not surprised by the
    enhanced sentence, was aware from the outset that his
    previous conviction could lead to an enhanced sentence,
    never challenged the validity of the prior conviction,
    and admitted it at the sentencing hearing, the statute
    prohibits an enhanced sentence unless the government
    first seeks it by properly filing an information prior to
    trial.
    United States v. Weaver, 
    905 F.2d 1466
    , 1481 (11th Cir. 1990),
    cert. denied, 
    498 U.S. 1091
    , 
    111 S. Ct. 972
    ,          
    112 L. Ed. 2d 1058
    (1991);    see also 
    Noland, 495 F.2d at 533
    (same).       Accordingly, we
    -49-
    vacate Gregg's sentence and remand this matter to the district
    court for resentencing.
    VII
    For the foregoing reasons, we REMAND to permit the district
    court   to   determine   in   the   first   instance   whether   the   notes
    described herein constitute either Jencks Act or Brady material.
    We REVERSE as to Gregg's sentence and REMAND for resentencing.           We
    AFFIRM the district court's decision in all other respects.
