    OPINION
    PER CURIAM:
    Robert Keith Neely appeals his convictions on money laundering
    and narcotics charges, contending that they are invalid on several
    grounds. Specifically, Neely claims that: (1) the district court erred in
    refusing to dismiss for prosecutorial misconduct; (2) the Government
    used documents in its investigation of Neely that he produced pursu-
    ant to a use-immunity order, in violation of Neely's Fifth Amendment
    right against compelled self-incrimination; (3) the Government know-
    ingly allowed counsel laboring under an actual conflict of interest to
    represent Neely, in violation of his Sixth Amendment right to coun-
    sel; (4) the Government abused the grand jury process; (5) the district
    court erred in permitting two Government case agents to remain in the
    courtroom during trial; and (6) Neely's convictions on Counts Two
    and Three are mutually exclusive, requiring vacatur of the conviction
    on Count Three. We reject all of these contentions and accordingly
    affirm Neely's convictions.
    I.
    The evidence presented at trial, viewed in the light most favorable
    to the Government, Glasser v. United States, 
    315 U.S. 60
    , 80 (1942),
    establishes the following facts. Until his convictions, Neely was an
    attorney with a sole-practice law firm, R. Keith Neely, P.C., in Chris-
    tiansburg, Virginia, specializing in criminal defense work. In May
    1986, while representing one of several defendants in a complex drug
    conspiracy case, Neely met Donald Kimbler, a private investigator
    from Miami, Florida, who was working for another attorney involved
    in the same case. At that time, Kimbler, a former agent for the Bureau
    of Alcohol, Tobacco, and Firearms (ATF), was a small-scale cocaine
    dealer in the Miami area, but had never used cocaine himself. Kim-
    bler and Neely quickly became close friends, and Neely introduced
    Kimbler to the use of cocaine.
    2
    At Kimbler's request, Neely introduced Kimbler to persons inter-
    ested in purchasing cocaine. Neely arranged a meeting between Kim-
    bler and Leigh Hurst, a drug dealer and longtime friend of Neely's.
    Hurst was wary of Kimbler's former connection to ATF, and refused
    to deal with Kimbler unless Neely acted as intermediary. Accord-
    ingly, Neely, Hurst, and Kimbler devised an arrangement pursuant to
    which Neely brokered cocaine transactions between Hurst and Kim-
    bler. Neely simply was present during some transactions, but on other
    occasions Neely received cocaine from Kimbler and delivered it to
    Hurst, who gave money to Neely for delivery to Kimbler. In return
    for his efforts, Neely received approximately $200 per ounce from
    Kimbler, or one-third of Kimbler's profits; Neely also received 2.5
    grams of cocaine from Hurst for every ounce Hurst purchased. Hurst
    estimated that he purchased eight pounds of cocaine from Kimbler
    through Neely from October 1986 through November 1987.
    Neely also introduced Kimbler to Fred Roland "Butch" Franklin,
    III, a high-school classmate of Neely's. As with Kimbler and Hurst,
    Neely facilitated cocaine transactions between Kimbler and Franklin.
    Kimbler estimated that he sold approximately 4.56 pounds of cocaine
    to Franklin through Neely.
    In 1987, Neely agreed to purchase a parcel of land near Claytor
    Lake in Pulaski County, Virginia for $50,000. Neely was to make a
    down payment of $8,000 and to pay the balance in quarterly install-
    ments of $4,200. Neely, evidently unable to meet this payment sched-
    ule, approached Kimbler and offered to make him a silent partner in
    the land purchase. Ultimately, Kimbler made the $8,000 down pay-
    ment and agreed to alternate installment payments with Neely. How-
    ever, Kimbler's name was not recorded on the deed to the property,
    nor was the agreement memorialized. Kimbler testified that the
    $8,000 used for the down payment came from a payment he had
    received for guarding a shipment of cocaine to Miami. Neely depos-
    ited the $8,000 into either his personal account or one of the law
    firm's corporate accounts, then drew a check on that account, payable
    to the seller of the land, for $8,000. This pattern of conduct was
    repeated for each quarterly payment made by Kimbler.
    In August 1988, Kimbler and Neely had a disagreement concerning
    the payments on the property, as a result of which Kimbler ceased to
    3
    make quarterly installment payments. Shortly thereafter, Neely sought
    to make a new partnership arrangement with another friend, Michael
    Giacolone, for the purpose of continuing the payments. Giacolone
    gave Neely $42,000 in cash in exchange for a one-half interest in the
    property; this money represented profits from drug transactions.
    Neely instructed his secretary to deposit the $42,000 into his corpo-
    rate and personal accounts in small increments in order to evade fed-
    eral reporting requirements. Although Neely and Giacolone executed
    a partnership agreement, Giacolone's name was never recorded on the
    deed to the property.
    The Government began to investigate Neely's activities in the late
    1980s. In a 1990 case unrelated to the instant offenses, Neely pleaded
    guilty to misdemeanor possession of cocaine after he was videotaped
    using cocaine with a government informant. Also in 1990, Neely was
    indicted on charges of tampering with a grand jury, although he evi-
    dently was never prosecuted.1
    A grand jury in the Western District of Virginia returned a
    fourteen-count, superseding indictment on September 22, 1992,
    charging Neely with racketeering, see 
    18 U.S.C.A. § 1962
    (c) (West
    1984) (Count One) (including six acts of racketeering); conspiracy to
    aid and abet the distribution of marijuana and cocaine, to possess with
    intent to distribute marijuana and cocaine, and to distribute marijuana
    and cocaine, see 
    18 U.S.C.A. § 2
     (West 1969), 
    21 U.S.C.A. § 841
    (a)(1) (West 1981) (Count Two); aiding and abetting the distri-
    bution of cocaine, see 
    18 U.S.C.A. § 2
    , 
    21 U.S.C.A. § 841
     (Count
    Three); money laundering, see 18 U.S.C.A.§ 1956(a)(1)(B)(i) (West
    Supp. 1995) (Counts Four through Nine);2 distribution of marijuana,
    _________________________________________________________________
    1 The district court dismissed the indictment because the prosecution
    failed to provide exculpatory evidence to the grand jury. The Govern-
    ment appealed, and we reversed on the authority of United States v.
    Williams, 
    504 U.S. 36
     (1992) (holding that prosecutor is not required to
    present exculpatory evidence to the grand jury). See United States v.
    Neely, 
    966 F.2d 1445
     (4th Cir. 1992) (per curiam) (unpublished), cert.
    denied, 
    113 S. Ct. 1261
     (1993). Although the record before us is unclear,
    apparently the Government did not re-indict Neely.
    2 Counts Four and Five related to Neely's dealings with Kimbler
    regarding the Claytor Lake property. Counts Six through Nine charged
    Neely with money laundering related to his various dealings with Giaco-
    lone, including the $42,000 paid by Giacolone for a one-half interest in
    the Claytor Lake property (Count Seven).
    4
    see 
    21 U.S.C.A. § 841
    (a)(1) (Count Ten); accessory after the fact to
    Giacolone's drug offenses, see 18 U.S.C.A.§ 3 (West Supp. 1995)
    (Counts Eleven and Twelve); tampering with a witness, see 
    18 U.S.C.A. § 1512
     (West Supp. 1995) (Count Thirteen); and criminal
    forfeiture of certain assets and property, see 
    18 U.S.C.A. § 982
     (West
    Supp. 1995) (Count Fourteen). The district court dismissed Counts
    Twelve and Thirteen and one act of racketeering prior to trial, and
    Neely proceeded to trial on the remaining counts. After a two-week
    trial, the jury convicted Neely of conspiracy to possess cocaine for
    personal use (the lesser included offense of Count Two), aiding and
    abetting the distribution of cocaine (Count Three), money laundering
    (Count Seven), and distribution of marijuana (Count Ten).3 The dis-
    trict court sentenced Neely to 121 months imprisonment, but released
    him on bond pending appeal.
    Throughout the pretrial proceedings, trial, and post-trial proceed-
    ings, Neely filed a plethora of motions seeking to exclude evidence
    or to dismiss the indictment altogether. Although Neely has been
    somewhat more selective in his arguments on appeal, he nevertheless
    asserts a broad array of reversible errors. We address these conten-
    tions seriatim.
    II.
    Neely first asserts that the district court erred in denying his numer-
    ous motions to dismiss the indictment for prosecutorial misconduct.4
    Relying in part on the precept that, "while [the prosecutor] may strike
    hard blows, he is not at liberty to strike foul ones," Berger v. United
    States, 
    295 U.S. 78
    , 88 (1935), overruled on other grounds by Stirone
    v. United States, 
    361 U.S. 212
     (1960), Neely urges us to vacate his
    convictions on two grounds. First, Neely claims that the Government
    committed certain acts of misconduct during the course of the investi-
    gation and preparation of the case against Neely. Second, Neely
    claims that the Government withheld numerous pieces of exculpatory
    _________________________________________________________________
    3 Neely's conviction for distribution of marijuana was based on his pro-
    vision of marijuana to Shirley Bassett, a friend.
    4 Neely moved to dismiss the indictment based on allegations of pro-
    secutorial misconduct and withholding of exculpatory evidence no fewer
    than five times.

    evidence in violation of Brady v. Maryland, 
    373 U.S. 83
     (1963), and
    its progeny.
    The duty of the Government is not to obtain a conviction, but
    rather is to ensure that justice is achieved. Berger, 
    295 U.S. at 88
    . Jus-
    tice is not obtained, and reversal is required, when improper conduct
    by the prosecutor "so infect[s] the trial with unfairness as to make the
    resulting conviction a denial of due process." Darden v. Wainright,
    
    477 U.S. 168
    , 181 (1986) (internal quotation marks omitted). In order
    to obtain reversal of his convictions based on misconduct by the Gov-
    ernment, Neely must satisfy a two-prong test: "`(1) the prosecutor's
    remarks or conduct must in fact have been improper, and (2) such
    remarks or conduct must have prejudicially affected the defendant's
    substantial rights so as to deprive the defendant of a fair trial.'"
    United States v. Brockington, 
    849 F.2d 872
    , 875 (4th Cir. 1988)
    (quoting United States v. Hernandez, 
    779 F.2d 456
    , 458 (8th Cir.
    1985)). To the extent that the district court makes factual findings
    regarding a defendant's claims of prosecutorial misconduct, our
    review is for clear error; in the absence of such findings, however, our
    review is plenary. United States v. McDonald, 
    61 F.3d 248
    , 253 (4th
    Cir. 1995). We first examine the acts of misconduct alleged by Neely
    and then proceed to an examination of his Brady claims.
    A.
    Neely claims that the Government committed three acts of miscon-
    duct during the investigation and preparation of the case against him.
    First, Neely contends that the Government violated its duty to inform
    the district court of the existence of a conflict of interest when it
    knowingly permitted Neely's former attorney, James C. Turk, Jr., to
    represent Hurst despite Turk's knowledge that Hurst intended to tes-
    tify against Neely. See United States v. Tatum , 
    943 F.2d 370
    , 379-80
    (4th Cir. 1991) ("[W]hen a conflict situation becomes apparent to the
    government, the government has a duty to bring the issue to the
    court's attention and, if necessary, move for disqualification of coun-
    sel."). We address this purported conflict in more detail in Part IV,
    infra. For purposes of addressing Neely's prosecutorial misconduct
    claim, we need only note that Turk did not represent Neely on the
    instant charges; thus, any conflict that may have existed was not
    related to this case, and, even if the Government did have a duty to
    6
    inform the court of the presence of a conflict, that duty did not exist
    in this case. See generally Hoffman v. Leeke, 
    903 F.2d 280
    , 285-86
    (4th Cir. 1990) (delineating circumstances in which attorney faces
    actual conflict of interest).
    Second, Neely maintains that the Government violated his Sixth
    Amendment right to counsel when it, knowing that Neely was repre-
    sented by counsel on pending charges of grand jury tampering,
    equipped Hurst with a recording device and tape-recorded two con-
    versations between Neely and Hurst. See Massiah v. United States,
    
    377 U.S. 201
     (1964) (holding that covert interrogation of defendant
    after right to counsel has attached violates Sixth Amendment). Of
    course, Neely is correct that, under Massiah, "[a]ny secret interroga-
    tion of the defendant, from and after the finding of the indictment,
    without the protection afforded by the presence of counsel" is a viola-
    tion of the defendant's Sixth Amendment right to counsel. 
    Id. at 205
    (internal quotation marks omitted). The Sixth Amendment right to
    counsel, however, "is offense specific. It cannot be invoked once for
    all future prosecutions, for it does not attach until a prosecution is
    commenced," e.g., upon the return of an indictment. McNeil v.
    Wisconsin, 
    501 U.S. 171
    , 175 (1991); see also Kirby v. Illinois, 
    406 U.S. 682
    , 689 (1972) (stating that the Sixth Amendment right to coun-
    sel attaches upon "the initiation of adversary judicial criminal
    proceedings--whether by way of formal charge, preliminary hearing,
    indictment, information, or arraignment"). Accordingly, the mere fact
    that an individual has been indicted for a criminal offense does not
    preclude the investigation of other suspected criminal activity:
    The police have an interest . . . in investigating new or addi-
    tional crimes [after an individual is formally charged with
    one crime.] . . . [T]o exclude evidence pertaining to charges
    as to which the Sixth Amendment right to counsel had not
    attached at the time the evidence was obtained, simply
    because other charges were pending at that time, would
    unnecessarily frustrate the public's interest in the investiga-
    tion of criminal activities.
    Maine v. Moulton, 
    474 U.S. 159
    , 179-80 (1985); see also 
    id.
     at 180
    n.16 ("Incriminating statements pertaining to other crimes, as to
    which the Sixth Amendment right has not yet attached, are, of course,
    7
    admissible at a trial of those offenses."); United States v. Kidd, 
    12 F.3d 30
    , 32 (4th Cir. 1993) (same), cert. denied , 
    114 S. Ct. 1629
    (1994).
    Neely's claim that the Government violated Massiah is based on
    the fact that he was represented by counsel at the time of the tape-
    recorded conversations with Hurst. When the tape-recorded conversa-
    tions occurred, however, Neely was represented by counsel on
    charges of conspiracy to defraud the United States by interfering with
    grand jury secrecy, see 
    18 U.S.C.A. § 371
     (West 1966 & Supp. 1995),
    obstruction of justice, see 18 U.S.C.A.§ 1503 (West Supp. 1995), and
    criminal contempt, see 
    18 U.S.C.A. § 401
    (3) (West 1966).5 United
    States v. Neely, 
    966 F.2d 1445
     (4th Cir. 1992) (per curiam) (unpub-
    lished), cert. denied, 
    113 S. Ct. 1261
     (1993), but had not yet been
    indicted on the instant charges. Hence, although any incriminating
    statements made by Neely with respect to the pending charges would
    have been inadmissible, any incriminating statements made by Neely
    relating to allegations not yet charged would have been admissible
    against Neely at a trial on those charges. See United States v.
    DeVillio, 
    983 F.2d 1185
    , 1190-91 (2d Cir. 1993) (affirming admission
    of incriminating statements related to uncharged offense that were
    obtained after defendants had been indicted for another crime).
    Indeed, DeVillio is particularly instructive in light of the fact that in
    that case, the defendants made incriminating statements that related
    to both charged and uncharged offenses during the course of a
    covertly recorded conversation between the defendants and a codefen-
    dant acting as a government informant. In holding that the statements
    related to the uncharged crime were admissible, the Second Circuit
    implicitly concluded that the inadmissibility of the statements related
    to the charged offense did not taint statements regarding the
    uncharged offense. See 
    id. at 1191
    . Hence, for the Government to tape
    record Hurst's conversations with Neely in an effort to obtain evi-
    dence against Neely for use in prosecuting him on the instant charges
    was not improper.6
    _________________________________________________________________
    5 At the time of the recorded conversations, the district court had dis-
    missed these charges, and the Government's appeal was pending before
    this court.
    6 Even if the Government's conduct had been improper, the impropri-
    ety could not have denied Neely a fair trial because the district court
    excluded from evidence the tape-recorded conversations.
    8
    Third, Neely posits that the Government deliberately misled the
    district court and his attorneys respecting Kimbler's condition and
    ability to travel. According to Neely, the Government claimed that
    Kimbler was too ill to travel from a federal prison in Missouri to Roa-
    noke, Virginia to be deposed; accordingly, Neely's attorneys travelled
    to Missouri to take Kimbler's deposition. Upon arriving, they discov-
    ered that Kimbler was to be transferred to a federal prison in Florida
    for a hearing on a motion to be released from custody. In short, Neely
    argues, the Government misled the district court and defense counsel
    about the need to travel to Missouri. Of course, if Neely's allegations
    are true, substantial questions are raised concerning the Government's
    conduct, and, unfortunately, the Government does not dispute the fac-
    tual basis of this claim. Nevertheless, even if we were to assume that
    the Government acted improperly, we would not reverse Neely's con-
    victions because Neely made no showing that the misconduct so prej-
    udiced him as to deny him a fair trial. See Brockington, 
    849 F.2d at 875
    . Indeed, the fact that Kimbler was deposed by Neely's defense
    counsel prior to trial indicates that any prosecutorial misconduct with
    respect to representations about Kimbler's location and condition did
    not deprive Neely of a fair trial.
    B.
    Neely also contends that the Government's repeated failure to turn
    over exculpatory evidence was a part of a pattern of misconduct and
    that this misconduct constituted a due process violation. Neely alleges
    five instances of nondisclosure by the Government: (1) impeachment
    evidence regarding Hurst's conviction for perjury, his use of narcot-
    ics, and his illegal narcotics-dealing activities; (2) impeachment mate-
    rials related to Kimbler, including a tape recording of a debriefing of
    Kimbler by federal agents regarding Kimbler's participation in an
    interstate drug ring; (3) impeachment materials relevant to the testi-
    mony of Jamel Agemy, a Government witness; (4) information relat-
    ing to the Government's seeking early release and a reduction in fine
    for Giacolone in exchange for his testimony; and (5) information
    regarding a statement by Gary Duncan, an individual on the Govern-
    ment's witness list, that Duncan and Kimbler had not used drugs
    together. We address these challenges in turn, keeping in mind that
    a determination of whether the Government acted improperly neces-
    sarily requires a determination of whether any Brady violation in fact
    9
    occurred; if there was no Brady violation, the Government's conduct
    cannot be considered improper.
    Brady v. Maryland, 373 U.S 83 (1963), and its progeny require that
    the Government disclose to the defense all material evidence that is
    favorable to the accused. This duty applies equally to evidence that
    is directly exculpatory and to evidence that allows the defendant to
    impeach a witness. See United States v. Bagley , 
    473 U.S. 667
    , 676
    (1985). However, the Government has no duty to disclose evidence
    that could have been discovered through the exercise of due diligence
    by the defendant. See United States v. Wilson , 
    901 F.2d 378
    , 380 (4th
    Cir. 1990). Thus, there is no Brady violation if "the exculpatory infor-
    mation is not only available to the defendant but also lies in a source
    where a reasonable defendant would have looked." 
    Id. at 381
    .
    Not every failure to disclose favorable information requires that the
    defendant's conviction be vacated; rather, "the suppression by the
    prosecution of evidence favorable to an accused . . . violates due pro-
    cess [only] where the evidence is material either to guilt or to punish-
    ment, irrespective of the good faith or bad faith of the prosecution."
    Brady, 
    373 U.S. at 87
    . Evidence is material"if there is a reasonable
    probability that, had the evidence been disclosed to the defense, the
    result of the proceeding would have been different." Bagley, 
    473 U.S. at 682
    . A "reasonable probability" of a different result exists "when
    the Government's evidentiary suppression `undermines confidence in
    the outcome of the trial.'" Kyles v. Whitley , 
    115 S. Ct. 1555
    , 1566
    (1995) (quoting Bagley, 
    473 U.S. at 678
    ).
    With respect to Neely's first alleged instance of nondisclosure, we
    note that this claim relates to the Government's failure to disclose evi-
    dence that could be used to impeach Hurst during a hearing regarding
    pre-trial detention. Brady, however, is concerned only with the ques-
    tion of whether the defendant received a fair trial. Because Neely
    does not claim that the Government failed to provide the information
    in sufficient time for it to be used at trial, see United States v. Smith
    Grading & Paving, Inc., 
    760 F.2d 527
    , 532 (4th Cir.), cert. denied,
    
    474 U.S. 1005
     (1985), we conclude that Neely's first allegation of
    nondisclosure does not state a cognizable Brady claim.
    Similar reasoning applies to Neely's second claim of nondisclo-
    sure, which relates to the Government's alleged failure to provide,
    10
    prior to the taking of Kimbler's deposition, a tape recording of a
    debriefing of Kimbler that revealed his involvement in an interstate
    drug conspiracy and a murder-for-hire scheme. Even if Neely did not
    receive the tape recording prior to Kimbler's deposition (a fact that
    is not at all clear), the parties do not dispute that the recording was
    provided to defense counsel well in advance of trial. As noted above,
    the fact that Neely received the tape recording in time to use it at trial
    precludes a Brady claim.
    With respect to Neely's third allegation of nondisclosure, the dis-
    trict court found that the Government's failure to disclose two investi-
    gation reports containing information useful in impeaching Agemy
    constituted a Brady violation and, accordingly, excluded Agemy's
    testimony. Obviously, the fact that Agemy never testified precludes
    a finding that the Brady violation related to Agemy's testimony
    undermines confidence in the verdict.
    Neely's fourth contention is that the Government failed to reveal
    that Giacolone was promised early release from prison and a reduc-
    tion in fine in exchange for his testimony. The Government argues
    that this contention lacks a factual basis, claiming that Giacolone in
    fact received only a two-week furlough so that he could help the Gov-
    ernment prepare its case and that no agreement existed between the
    Government and Giacolone regarding a reduction in Giacolone's fine.
    Furthermore, the Government asserts, any promises made to Giaco-
    lone could have been discovered through diligent cross-examination
    of Giacolone. Because this information could have been discovered
    through due diligence by defense counsel, the Government posits, it
    had no duty under Brady to disclose it. We agree with the Govern-
    ment that any promises actually made to Giacolone could have been
    discovered by defense counsel during cross-examination. Addition-
    ally, we note that Brady does not necessarily require that exculpatory
    information be produced prior to trial; provided the information is dis-
    covered in time for its effective use by the defense, there is no Brady
    violation. See Smith Grading & Paving, 760 F.2d at 532 (holding that
    disclosure of exculpatory evidence during cross-examination of first
    Government witness did not violate Brady). Therefore, we conclude
    that there is no Brady violation here because Neely himself, through
    the exercise of due diligence, could have obtained information regard-
    11
    ing any promises made to Giacolone in time to use it effectively at
    trial.
    Finally, Neely claims that the Government violated Brady by con-
    cealing a statement by Duncan that he had never used cocaine with
    Kimbler. Neely argues that this statement would have allowed him to
    impeach Kimbler's testimony. While this may or may not be true,
    Neely cannot show that Duncan's statement was material to his
    defense. Neely employed a host of impeachment material during his
    cross-examination of Kimbler, most of it far more damning than Dun-
    can's statement. Accordingly, we conclude that assuming the Govern-
    ment was obligated to disclose Duncan's statement to the defense, the
    failure to do so does not give rise to a reasonable probability that, had
    the statement been disclosed, the outcome of the trial would have
    been different.
    III.
    Second, Neely maintains that his convictions were obtained in vio-
    lation of his Fifth Amendment right against compelled self-
    incrimination. Specifically, Neely contends that he produced two sets
    of documents pursuant to immunity orders and that the Government
    violated those immunity orders by: (1) using documents to prepare its
    case against Neely; (2) referring to Neely as the source of documents
    before the grand jury; and (3) referring to Neely as the source of doc-
    uments at trial. We conclude that none of these claims has merit.
    The Fifth Amendment provides in part that no person"shall be
    compelled in any criminal case to be a witness against himself." U.S.
    Const. amend. V. The Supreme Court has held repeatedly that the
    contents of voluntarily prepared business records are not protected by
    the Fifth Amendment because, while possibly incriminating, their cre-
    ation was not compelled. See, e.g., United States v. Doe, 
    465 U.S. 605
    , 610 (1984) ("[T]he Fifth Amendment protects the person assert-
    ing the privilege only from compelled self-incrimination. Where the
    preparation of business records is voluntary, no compulsion is pres-
    ent." (citation & footnote omitted)); Fisher v. United States, 
    425 U.S. 391
    , 409 (1976) ("[T]he Fifth Amendment would not be violated by
    the fact alone that [an accountant's workpapers] on their face might
    incriminate the [defendant], for the privilege protects a person only
    12
    against being incriminated by his own compelled testimonial commu-
    nications. . . . Furthermore, . . . the preparation of all of the papers
    sought in these cases was wholly voluntary . . . ." (citations omitted)).
    Whether the act of producing business records has independent tes-
    timonial significance and may not be compelled absent a grant of
    immunity coextensive with the privilege is, however, another ques-
    tion. Thus, even though the contents of business records are not pro-
    tected,
    "[t]he act of producing evidence in response to a subpoena
    nevertheless has communicative aspects of its own, wholly
    aside from the contents of the papers produced. Compliance
    with the subpoena tacitly concedes the existence of the
    papers demanded and their possession or control by the
    [defendant]. It would also indicate the [defendant's] belief
    that the papers are those described in the subpoena. The ele-
    ments of compulsion are clearly present, but the more diffi-
    cult issues are whether the tacit averments of the[defendant]
    are both `testimonial' and `incriminating' for purposes of
    applying the Fifth Amendment. These questions perhaps do
    not lend themselves to categorical answers; their resolution
    may instead depend on the facts and circumstances of par-
    ticular cases or classes thereof."
    Braswell v. United States, 
    487 U.S. 99
    , 103 (1988) (quoting Fisher,
    
    425 U.S. at 410
    ) (citation omitted). According to the Braswell court,
    the custodian of corporate records does not possess a Fifth Amend-
    ment privilege against the production of those records, because he
    holds those records only as a representative of the organization. See
    id. at 104. However, in the case of a sole proprietorship, Braswell
    holds that, under Doe, the custodian of the records must "be provided
    the opportunity to show that his act of production would entail testi-
    monial self-incrimination." Id. If the custodian makes such a showing,
    the Government cannot compel production of the records unless it
    first grants the custodian immunity coextensive with the scope of the
    privilege. See Kastigar v. United States, 
    406 U.S. 441
    , 449 (1972).
    The district court's conclusion with respect to whether an individual
    is entitled to immunity for his act of producing business records is a
    13
    finding of fact that we may overturn only if it is unsupported by the
    record. See Doe, 
    465 U.S. at 613-14
    .
    In December 1990, the grand jury issued a subpoena addressed to
    "ROBERT KEITH NEELY, ESQ., Custodian of Records for sole
    practice law firm" requesting "ANY AND ALL client related records
    and documents . . . relative to Michael Giacolone, Jamel Agemy,
    James Regan for the period 1980 to September 1990." (J.A. at 508,
    510) (Document Set One.) Neely moved to quash the subpoena, argu-
    ing that the documents were protected by attorney-client privilege and
    that being required to produce the records would violate his Fifth
    Amendment right against compelled self-incrimination. After the dis-
    trict court granted the motion to quash, Neely agreed to produce the
    documents pursuant to a grant of immunity. Thereafter, at the Gov-
    ernment's request, the district court entered an order granting Neely
    immunity for "testimony or . . . other information which he refuses
    to give or to provide on the basis of his privilege against self incrimi-
    nation." (J.A. at 543-44.) Neely then produced the documents.
    In May 1991, the grand jury served another subpoena, addressed
    to "Keith Neely, Custodian of Records, R. Keith Neely, P.C.," seek-
    ing "ANY AND ALL records, files, [etc.] . .. maintained by the
    R. Keith Neely law firm" related to the purchase of the Claytor Lake
    property and to Kimbler, Hurst, and Franklin. (J.A. at 1151, 1153)
    (Document Set Two.) Neely moved to quash this subpoena; in
    response, the Government moved for an order of act-of-production
    immunity. After examining the subpoenaed documents in camera, the
    district court granted in part Neely's motion to quash. The district
    court held that some of the documents were subject to attorney-client
    privilege and that the compulsory production of others would violate
    Neely's right against compelled self-incrimination. With respect to
    the rest, the district court concluded that the documents were corpo-
    rate papers not protected by the Fifth Amendment. 7 Neely subse-
    _________________________________________________________________
    7 The district court's rulings with respect to the two sets of documents
    leave some question as to whether it viewed R. Keith Neely, P.C. as a
    sole proprietorship or as a corporation. We need not resolve this ambigu-
    ity because the contents of the subpoenaed documents were not privi-
    leged under either characterization and because we conclude that,
    assuming Neely's act of producing the documents was protected by a
    Fifth-Amendment privilege, any reference to Neely as the source of the
    documents was harmless beyond a reasonable doubt.
    14
    quently produced these documents.8
    Neely argues that the district court granted him use immunity for
    the contents of Document Set One, and therefore claims that the Gov-
    ernment violated his right against compelled self-incrimination in
    showing the documents to two witnesses, Giacolone and Tangie Vest,
    a former employee of Neely's, to help the Government prepare for
    trial. In response, the Government argues first, that the order grants
    Neely only act-of-production immunity, and second, that even if the
    order did grant use immunity, the documents are corporate records
    and therefore not protected by the Fifth Amendment. After a lengthy
    hearing on this issue, the district court found that Neely "would enjoy
    immunity as to any act of production, but not as to the contents of the
    documents produced. While the order granting immunity was broad
    enough to cover any activity or testimony of the defendant, the evi-
    dence shows that the only testimonial act the defendant performed
    was producing the records." (J.A. at 663.)
    We cannot conclude that the district court's finding that Neely's
    only testimonial act was the production of Document Set One is
    clearly erroneous. See Doe, 
    465 U.S. at 613-14
    . The subpoena clearly
    sought business records of the law firm, and Neely does not dispute
    that those records were created voluntarily. Accordingly, Neely pos-
    sessed no Fifth Amendment right with respect to the contents of those
    documents. See 
    id. at 610
    . And, given that Neely operated his law
    firm as a sole practitioner, the district court's finding that Neely was
    entitled to immunity for his act of producing the documents is not
    clearly erroneous. Thus, although the Government was barred from
    using Neely's act of producing Document Set One against him, it was
    free to use the contents of Document Set One to prepare its case
    against Neely.9
    _________________________________________________________________
    8 We can find no support in the record for Neely's assertion that the
    district court granted the Government's motion for act-of-production
    immunity. The document to which Neely points, (see J.A. at 562-63), is
    simply a draft order submitted by the Government with its motion. The
    draft order was never signed by the district court.
    9 Neely argues that, having granted him use immunity, the Government
    was required to show that none of the evidence offered against Neely at
    15
    The district court's finding that Neely was entitled to immunity for
    his act of producing Document Set One necessarily means that Agent
    Higginbotham acted improperly when he referred to Neely as the
    source of Document Set One before the grand jury that received those
    documents. Indeed, the Government does not dispute that Agent Hig-
    ginbotham's comments violated Neely's Fifth Amendment right.
    Rather, the Government contends that the violation was harmless
    beyond a reasonable doubt and reversal of Neely's convictions there-
    fore is not required. See United States v. Harris, 
    973 F.2d 333
    , 338
    (4th Cir. 1992) (noting that use of compelled testimony does not
    require reversal if error is harmless beyond a reasonable doubt). In
    advancing this contention, the Government rightly points out that, in
    addition to the fact that the Government reminded the grand jury that
    it was not to consider that Neely had produced the documents, the
    grand jury that indicted Neely was not the same grand jury that
    received the records, and no improper references were made to Neely
    as the source of Document Set One before the grand jury that actually
    indicted him. Under these circumstances, we conclude that neither
    Neely's indictment nor his trial suffered even the slightest taint from
    the improper references and that the error was harmless beyond a rea-
    sonable doubt.
    Neely also contends that reversal of his convictions is required
    because IRS Agent Suzanne Hines, who testified at trial regarding
    various financial records including several checks that had been pro-
    duced pursuant to one of the grand jury subpoenas, referred to "the
    defense" as the source of the checks. (J.A. at 871WW.) According to
    Neely, Hines's statement requires reversal of his convictions because
    it referred to Neely's testimonial act of producing the documents,
    thereby violating his right against compelled self-incrimination. The
    Government concedes that Hines's statement constituted error but
    maintains that the district court correctly determined that this error
    was harmless beyond a reasonable doubt.
    _________________________________________________________________
    trial was derived from the contents of Document Set One. See Kastigar,
    
    406 U.S. at 460
    . Because the documents were not privileged, however,
    there was no prohibition against the Government using them to prepare
    its case against Neely. Neely's claim that the Government failed to meet
    its burden under Kastigar is therefore misplaced.
    16
    In concluding that Hines's reference to Neely as the source of doc-
    uments was harmless beyond a reasonable doubt, the district court
    employed the test of Williams v. Zahradnick, 
    632 F.2d 353
    , 361-62
    (4th Cir. 1980). Under Williams, the determination of whether an
    error is harmless beyond a reasonable doubt depends on five factors:
    (1) the use to which the Government put the improper reference; (2)
    "[w]ho elected to pursue the line of questioning"; (3) "[t]he quantum
    of other evidence indicative of guilt"; (4) "[t]he intensity and fre-
    quency of the reference"; and (5) "[t]he availability to the trial judge
    of an opportunity to grant a motion for mistrial or to give curative
    instructions." 
    Id.
     The district court concluded that none of these fac-
    tors weighed in favor of reversal, noting that the reference was brief,
    equivocal, and inadvertent; that the evidence of Neely's guilt was
    substantial; and that the court had considered and rejected the options
    of a mistrial or a curative instruction.10 The district court was in the
    best position to observe the impact of Agent Hines's remark in the
    context of the trial as a whole. Hence, we are reluctant to disturb the
    district court's carefully considered ruling that the error was harmless
    beyond a reasonable doubt. Moreover, our review of the record leaves
    us with no doubt as to the fleeting nature of the reference and its mini-
    mal significance when considered in light of all of the evidence pres-
    ented during the lengthy trial. We therefore agree with the district
    court that this error does not warrant reversal because it was harmless
    beyond a reasonable doubt.
    IV.
    Next, Neely mounts a Sixth Amendment challenge to his convic-
    tions. Specifically, he posits that he was deprived of his Sixth Amend-
    ment right to counsel because the Government knowingly allowed his
    former attorney to represent one of the Government's witnesses on
    charges unrelated to the investigation of Neely. According to Neely,
    the Government failed to disclose to the district court a known con-
    flict of interest, thereby resulting in Neely's being represented by
    counsel with an actual conflict of interest. Neely asserts that this vio-
    _________________________________________________________________
    10 The district court stated that it elected not to give a curative instruc-
    tion because it feared that the cure would be worse than the disease, i.e.,
    that the curative instruction would draw more attention to the error than
    it warranted.
    17
    lation of his Sixth Amendment right to counsel entitles him to a new
    trial.
    The district court held a lengthy hearing on Neely's Sixth Amend-
    ment claim, at which the following facts were adduced. The Govern-
    ment's investigation of Neely, led by FBI Agent Gerald Fayed and
    IRS Agent Hines, began sometime in the late 1980s. In 1990, Neely
    pleaded guilty to misdemeanor cocaine possession. Neely was repre-
    sented in the case by his friend Turk. Neely was placed on probation
    after his guilty plea; at this point Turk believed that his representation
    of Neely had ended.
    In March 1992, Neely contacted Turk and requested that Turk rep-
    resent Hurst, who had been charged with money laundering and
    released on bond. Turk undertook the representation only after being
    assured by both Neely and Hurst that no conflict of interest existed.
    At approximately the same time, Turk made several inquiries to the
    court and to the probation office regarding the possibility of an early
    release from probation for Neely. Turk avowed that he made the
    inquiries as a favor to Neely, not as his counsel, emphasizing to the
    district court that he informed Neely that he was not representing
    Neely at that time. Turk's last activity regarding Neely's probation
    status occurred on April 15, 1992.
    Shortly after he agreed to represent Hurst, the Government
    informed Turk of its belief that Hurst, Neely, and Kimbler had partici-
    pated jointly in drug-related activities and offered the possibility of a
    reduced sentence for Hurst if he agreed to testify against Neely. Addi-
    tionally, Turk reviewed discovery material in the Government's pos-
    session and found an affidavit by Kimbler indicating that Hurst and
    Neely might be linked to drug trafficking. In response to Turk's
    inquiry, Hurst stated that he did not want to testify against Neely, but
    did not admit or deny the truth of the Government's allegations
    regarding his association with Neely. According to Turk, Neely
    repeatedly contacted him regarding the Hurst case, making inquiries
    and suggesting strategies in a manner that made Turk suspect that
    "Neely was trying to manipulate Hurst's defense in order to protect
    himself." (J.A. at 1358.)
    On May 12, 1992, the Government moved to revoke Hurst's bond
    on the basis of a urinalysis that tested positive for cocaine use. Hurst
    18
    informed Turk that Neely gave him the cocaine that had resulted in
    the positive urinalysis and told Turk that he now wished to testify
    against Neely. At that point, Turk informed Hurst that he could no
    longer serve as his attorney and advised him to seek new counsel.
    Before officially withdrawing as counsel, however, Turk attended a
    meeting between Hurst and the Government to negotiate a plea agree-
    ment. After the meeting, Hurst met with Government investigators
    several more times and met with Neely while wearing a recording
    device. Turk stated that he had no specific knowledge of these activi-
    ties and that he did not provide Hurst with any legal advice regarding
    them. Turk was present at Hurst's plea hearing because Hurst's sub-
    stitute counsel was unavailable. At that time, Turk informed the court
    of the conflict and formally withdrew as counsel.
    Prior to trial, Neely moved to suppress Hurst's testimony on the
    basis that Turk's simultaneous representation of Hurst (on money
    laundering charges unrelated to Neely) and Neely (on early release
    from probation) violated Neely's right to counsel in this case. The dis-
    trict court held a lengthy hearing at which Turk and others testified.
    Ruling from the bench, the district court concluded that, regardless of
    Turk's view that he was not "representing" Neely with respect to
    Neely's probation status, Turk remained Neely's counsel throughout
    Turk's representation of Hurst. The court also opined, however, that
    Neely's Sixth Amendment right with respect to the instant charges
    was not implicated by the dual representation because Neely had not
    yet been indicted. Additionally, the district court held that any preju-
    dice to Neely from the dual representation affected only Neely's pos-
    sible early release from probation, not the pending charges.
    That a defendant's Sixth Amendment right to counsel includes the
    right to counsel free from serious conflicts of interest is beyond ques-
    tion. See Hoffman, 
    903 F.2d at 285
    . A defendant's right to counsel has
    been violated when an "actual conflict of interest adversely affect[s]
    his lawyer's performance." 
    Id. at 286
     (internal quotation marks omit-
    ted). Such a conflict exists when an attorney simultaneously repre-
    sents two individuals whose interests are adverse. See 
    id. at 285
    .
    Neely's Sixth Amendment claim is patently without merit. Assum-
    ing that Turk labored under an actual conflict of interest in his simul-
    taneous representation of Hurst and Neely, this conflict related only
    19
    to Turk's representation of Neely on the cocaine-possession matter.
    Because Turk did not represent Neely on the instant charges --
    indeed, the conflict was resolved before Neely was even indicted on
    these charges -- Neely was not represented by counsel laboring under
    an actual conflict of interest, and could not have suffered a depriva-
    tion of his right to counsel.
    V.
    Neely further contends that the Government abused the grand jury
    process by commencing a grand jury investigation of Franklin before
    Neely's trial took place. According to Neely, the investigation of
    Franklin was a mere pretext for the Government's real purpose,
    namely acquiring more evidence against Neely. The Government
    counters that its investigation of Franklin was legitimate. We find
    Neely's claim to be without merit.
    A court should not intervene in the grand jury process absent a
    compelling reason. See United States v. Dionisio , 
    410 U.S. 1
    , 16-18
    (1973). A presumption of regularity attaches to grand jury proceed-
    ings, and Neely has the burden of showing that this presumption is
    unwarranted. See United States v. Moss, 
    756 F.2d 329
    , 332 (4th Cir.
    1985). While the Government may not utilize a grand jury "solely or
    even primarily for the purpose of gathering evidence in pending liti-
    gation," 
    id.,
     the existence of a pending indictment does not preclude
    the Government from using a grand jury to make a good-faith inquiry
    into charges not included in the indictment, 
    id.
     Provided investigation
    of the defendant is not the Government's "sole or dominant purpose"
    in convening the grand jury, no abuse of the grand jury process has
    occurred. 
    Id.
     The advantage of this rule is that it allows grand juries
    to conduct continuing investigations without waiting to indict persons
    against whom sufficient evidence to indict has been obtained:
    Lacking clairvoyance, grand juries must be allowed to
    investigate freely individuals suspected of involvement in
    crimes for which indictments have already been issued.
    When applied correctly, the sole or dominant purpose test
    plainly permits grand juries to investigate additional individ-
    uals who become suspects only after an indictment has been
    20
    returned, while precluding improper use of the grand jury
    for discovery.
    
    Id.
     The district court's determination regarding the Government's sole
    or dominant purpose in conducting a grand jury investigation is a fac-
    tual finding, which we review only for clear error. 
    Id.
    Franklin was named, but not indicted, in the indictment charging
    Neely. After the indictment was returned, but before Neely's trial, a
    grand jury was convened to investigate Franklin on charges unrelated
    to the Neely indictment. Immediately upon learning of the investiga-
    tion, Neely filed an emergency motion to enjoin the grand jury pro-
    ceedings. The district court held an emergency hearing on Neely's
    motion, during which Neely asserted his belief that the investigation
    of Franklin was being used as a discovery device in the Government's
    case against Neely. In response, the Government proffered, under
    seal, its reasons for investigating Franklin. Agent Fayed testified that
    the grand jury's investigation of Franklin was related to Franklin's
    suspected distribution of marijuana and cocaine and that the Govern-
    ment had proceeded with its investigation of Franklin because its key
    witness, Kimbler, was suffering from terminal cancer, making it nec-
    essary to secure his testimony for trial in the form of a videotaped
    deposition. The Government, therefore, had to determine whether
    there was sufficient evidence against Franklin to indict him so that he
    could be present during the deposition.
    Based on this information, the district court concluded that the
    Government's investigation of Franklin was conducted in good faith,
    and that the investigation was not being carried out for the sole or
    dominant purpose of acquiring evidence against Neely. We cannot
    say that this finding was clearly erroneous, and accordingly, decline
    to reverse Neely's convictions on this basis.
    VI.
    Neely next maintains that the district court committed reversible
    error by allowing the Government to designate two case agents,
    Agents Fayed and Hines, both of whom were exempted from the
    21
    district court's order sequestering witnesses. See Fed. R. Evid. 615.11
    While we agree with Neely that an error was committed, we find the
    error harmless.
    Rule 615 provides for the exclusion of witnesses at the request of
    a party. Exclusion is a matter of right; once a request is made, the
    court "shall" sequester the witnesses. 
    Id.
     ; see United States v.
    Farnham, 
    791 F.2d 331
    , 334-35 (4th Cir. 1986). Rule 615 is designed
    to aid the truth-seeking process by denying the opportunity for wit-
    nesses to collude or for one witness to tailor his testimony to the testi-
    mony of another. See 
    id. at 334-35
    . Every witness need not be
    excluded, however. Rule 615 exempts from sequestration: (1) a party
    who is a natural person; (2) a designated representative of a party that
    is not a natural person; and (3) a person whose presence is essential
    to the presentation of the case. Fed. R. Evid. 615. That the Govern-
    ment's investigating agent may be exempted from sequestration pur-
    suant to Rule 615(2) is beyond dispute, see United States v. Parodi,
    
    703 F.2d 768
    , 773 (4th Cir. 1983); that the Government may desig-
    nate only one such agent is equally clear. Farnham, 
    791 F.2d at 335
    .
    The Government erroneously relies on United States v. Kosko, 
    870 F.2d 162
    , 164 (4th Cir.), cert. denied, 
    491 U.S. 909
     (1989), for the
    proposition that "a district court may permit two case agents to remain
    in the courtroom if their testimony does not overlap and undermine
    the integrity of the fact-finding process." (Appellee's Brief at 35.) In
    Kosko, we affirmed the district court's ruling allowing a DEA agent
    and an IRS agent, both of whom had participated in the investigation
    of the defendant, to remain in the courtroom during trial because the
    latter agent was present in the courtroom as an expert witness whose
    presence was essential to the presentation of the Government's case.
    _________________________________________________________________
    11 Rule 615 provides:
    At the request of a party the court shall order witnesses
    excluded so that they cannot hear the testimony of other wit-
    nesses, and it may make the order of its own motion. This rule
    does not authorize exclusion of (1) a party who is a natural per-
    son, or (2) an officer or employee of a party which is not a natu-
    ral person designated as its representative by its attorney, or (3)
    a person whose presence is shown by a party to be essential to
    the presentation of the party's cause.
    22
    Kosko, 870 F.2d at 164; see Fed. R. Evid. 615(3). Indeed, Kosko
    explicitly reaffirmed the holding of Farnham that the Government
    may designate only one case agent as its representative. Kosko, 870
    F.2d at 164. Regardless of the wisdom of the Government's position
    that a district court may designate more than one case agent when
    each agent represents a different governmental agency and their trial
    testimony will not overlap, we are bound by Farnham and Kosko to
    reject it.
    In short, the district court erred in permitting the Government to
    designate two case agents, both of whom were exempted from the
    sequestration order and both of whom testified at Neely's trial. The
    question remains, however, whether this error requires us to reverse
    some or all of Neely's convictions. See Farnham , 
    791 F.2d at 335
    (holding that a violation of Rule 615 does not require vacatur of con-
    victions if the error was harmless). Although both agents testified dur-
    ing the trial, their testimony concerned entirely different matters:
    Agent Fayed's testimony concerned Neely's telephone records, while
    Agent Hines testified regarding Neely's financial records. Cf. Kosko,
    870 F.2d at 164 (concluding that because "the testimony of the two
    agents did not overlap as to any matter on which they had personal
    knowledge, . . . their mutual presence during trial could not have
    undermined the integrity of the fact-finding process"); Farnham, 
    791 F.2d at 334
     (finding violation of Rule 615 not harmless when two
    agents testified regarding their personal knowledge of the same
    events). We therefore conclude that the error was harmless.
    VII.
    Finally, Neely contends that his convictions for conspiracy to pos-
    sess cocaine for personal use (Count Two) and aiding and abetting the
    distribution of cocaine (Count Three) are mutually exclusive, thereby
    requiring reversal of Count Three, the more serious crime. Specifi-
    cally, Neely claims that the affirmative finding of intent required for
    a conviction on the possession count -- i.e., the intent to possess
    cocaine -- necessarily precludes an affirmative finding of the intent
    required for conviction on the aiding and abetting count -- i.e., the
    intent to distribute cocaine -- because one cannot intend simulta-
    neously to possess something and to distribute it.
    23
    We are not persuaded by this argument. There was ample evidence
    from which the jury could conclude that Neely conspired with other
    individuals to obtain cocaine for his personal use while simulta-
    neously aiding and abetting Kimbler in his distribution activities. At
    most, the jury's verdicts on these counts are inconsistent, but this does
    not entitle Neely to an acquittal on Count Three. See United States v.
    Powell, 
    469 U.S. 57
    , 63 (1984); see also United States v. Arrington,
    
    719 F.2d 701
    , 705 (4th Cir. 1983) (concluding that acquittal on con-
    spiracy charge is not a valid basis for reversal of conviction on charge
    of aiding and abetting), cert. denied, 
    465 U.S. 1028
     (1984).
    VIII.
    We have reviewed carefully all of Neely's assignments of error and
    conclude that none of them warrants reversal of his convictions.
    Accordingly, Neely's convictions are affirmed.
    AFFIRMED
