    BRIEF: Steven R. Freeman, FREEMAN, WOLFE & GREENBAUM, P.A., Towson,
    Maryland, for Appellant.
    Unpublished opinions are not binding precedent in this circuit.
    See Local Rule 36(c).
    SHEDD, Circuit Judge:
    Robert Sanders, a Maryland attorney, filed suit against Olsman,
    Ganos & Mueller (“OGM”), a Michigan law firm, claiming entitlement
    to a share of attorneys fees recovered by OGM for representing
    clients in three separate personal injury cases -- the Ambrose,
    Greer, and Holtquist cases.         The district court granted summary
    judgment in favor of OGM on Sanders’ claim for attorneys fees in the
    Greer and Holtquist cases.       After the jury awarded Sanders $300,000
    for the reasonable value of the services he rendered in the Ambrose
    case, the district court granted OGM’s motion for judgment as a
    matter of law on the issue of damages and reduced Sanders’ award to
    $1.    For the following reasons, we reverse the grant of judgment as
    a matter of law in favor of OGM in the Ambrose case, reverse the
    grant of summary judgment in favor of OGM in the Greer and Holtquist
    cases on Sanders’ breach of contract claims, and affirm the grant
    of summary judgment in the Greer and Holtquist cases on Sanders’
    quantum meruit and unjust enrichment claims.
    I.
    Because we are reviewing a grant of judgment as a matter of law
    and summary judgment, we view the evidence in the light most
    favorable to Sanders. See Anderson v. G.D.C., Inc., 
    281 F.3d 452
    ,
    457 (4th Cir. 2002) (judgment as a matter of law); Williams v.
    Staples, Inc., 
    372 F.3d 662
    , 667 (4th Cir. 2004) (summary judgment).
    In    1995,   Sanders’   young   daughter   was   killed   in   a   low-impact
    2
    automobile collision.       Sanders claims that his daughter’s death
    resulted from the deployment of the air bag in his Chrysler minivan
    rather than from the force of the collision.                 Soon after his
    daughter’s tragic death, Sanders helped form a public interest group
    to lobby Congress to require air bag warnings in vehicles and to
    strengthen federal air bag performance requirements.
    Sanders also retained Wolfgang Mueller, a former Chrysler
    engineer and an associate at OGM, to file a products liability
    lawsuit against Chrysler.1       Although Mueller was a young lawyer
    who had never handled an air bag case, Sanders liked his technical
    background and aggressiveness.        Mueller agreed to allow Sanders to
    participate in preparing the case for trial.
    As a result of Sanders’ involvement with his lobbying group,
    he came into contact with several families across the nation whose
    children had been killed or injured in accidents involving air bag
    deployments.    If the families inquired about filing a lawsuit,
    Sanders referred them to Mueller. Sanders first recommended Mueller
    to Richard Kaplan, whose son suffered an eye injury from an air bag
    deployment. Although Sanders did not request any fee, Mueller wrote
    a letter to Sanders offering to pay him one-third of any attorney’s
    fees   recovered,   which   Mueller       represented   to   be   the   typical
    arrangement in Michigan.      Kaplan’s son recovered from his injury,
    1
    Sanders also sued Mueller in this action. The district court
    dismissed all claims against Mueller, and Sanders does not
    challenge that ruling.
    3
    and the case was not prosecuted.             Sanders thereafter recommended
    Mueller to several other families, including the Ambroses from
    Tennessee and the Greers from Idaho.            The Ambroses were originally
    represented     by   a   law   firm    in    Nashville,   Tennessee.   Sanders
    introduced    Mueller    to    the    Nashville   firm,   and   ultimately   the
    Nashville firm retained OGM as co-counsel in the Ambrose case.                As
    agreed between these two firms, OGM would receive 55% and the
    Nashville firm would receive 45% of attorneys fees recovered in the
    Ambrose suit.    The Greers were not represented by local counsel, so
    they directly retained Mueller of OGM.            After the Ambroses and the
    Greers retained Mueller, Mueller confirmed that Sanders would be
    allowed to perform legal work on these two cases and would receive
    the same one-third share of OGM’s fees that Mueller had promised in
    the Kaplan case.
    In April 1997, Mueller and Jules Olsman, the sole shareholder
    of OGM, proposed to modify their fee-sharing arrangement with
    Sanders. OGM explained that it did not want to have a straight one-
    third fee agreement with Sanders in the Ambrose case because it
    would not be financially feasible in light of its other fee-sharing
    agreement with the Nashville firm.                OGM instead proposed that
    Sanders’ fee in the Ambrose case would be based on the “totality of
    the circumstances,” including how much work Sanders performed in the
    case, his role in referring the client to OGM, how much of the
    litigation expenses he paid, and several other factors.              Depending
    on how these factors weighed, Sanders could receive less than one-
    4
    third or more than one-third of OGM’s fee.            By contrast, in cases
    such as Greer, where OGM was not retained by local counsel, Sanders’
    fee would remain the standard one-third.       Moreover, OGM would allow
    Sanders to perform legal work on all the cases.
    After    agreeing   to    this   modification,    Sanders   recommended
    Mueller to the Holtquists, a Minnesota family whose child had died
    in an air bag accident.       Mueller again confirmed that Sanders would
    be allowed to participate in the legal work on the case and would
    receive one-third of the fees recovered by OGM.
    The Ambrose case in Nashville was the first case scheduled for
    trial.    All the attorneys representing the Ambroses agree that the
    case was hotly disputed and extraordinarily time-consuming.           In the
    two years leading up to trial in Tennessee state court, the lead
    partner in the Nashville firm spent half her time working on the
    Ambrose case.     Mueller took nearly sixty depositions across the
    nation. Sanders discussed with Mueller the possibility of preparing
    a motion for partial summary judgment on the issue of liability.
    Mueller enthusiastically agreed with this strategy and sent Sanders
    several boxes of technical documents and deposition transcripts.
    Sanders spent half of his work days for the next six months
    reviewing and analyzing the technical background information on air
    bags that Mueller had sent and that he had discovered in his own
    research.     For the following three months he worked full-time
    drafting almost fifty versions of the partial summary judgment
    motion.     During this period, Sanders worked closely with Mueller,
    5
    talking with him by telephone at least once every day. Sanders sent
    at least three drafts of the motion to Mueller for review and
    comment.   The final motion advanced several technical arguments and
    was accompanied by nearly 1,000 pages of supporting documentation.
    Shortly before the scheduled trial, Mueller filed the Sanders motion
    on behalf of the Ambroses.   Although the Tennessee court denied the
    motion, Mueller considered the motion to be worthwhile.      Sanders
    also prepared several other pretrial motions to exclude certain
    defense evidence at trial as well as other filings to ensure
    admission of evidence helpful to the Ambroses.      Further, Sanders
    traveled to Tennessee to attend and critique a mock trial.    As the
    trial date neared, Mueller also asked Sanders to make plans to
    attend the trial to lend his expertise and counsel.          Sanders
    calculated that he worked a total of nearly 1,500 hours on the
    Ambrose case.    The vast majority of that time was spent researching
    and drafting the motion for partial summary judgment.
    Four days before trial and soon after the motion for partial
    summary judgment was denied, the Ambrose case settled.    OGM and the
    Nashville firm recovered more than $1 million in attorneys fees,
    with OGM receiving more than $550,000 and the Nashville firm
    receiving more than $450,000.
    Sanders requested from OGM his share of the attorneys fees that
    OGM recovered.    Olsman refused to pay Sanders any amount that could
    be considered a referral fee.      Instead, Olsman asked Sanders to
    verify how much time he expended on the case.         Olsman assured
    6
    Sanders that, once Olsman determined the amount of the fee for “the
    work and technical assistance” Sanders performed, Sanders would find
    the amount “to be significant and appropriate.”
    Although it had no fee-sharing agreement with Sanders, the
    Nashville law firm paid Sanders $20,000.       Sanders claims this
    payment was a gift from the Nashville firm in appreciation for his
    valuable work on the case.
    In October 1998, OGM and Sanders reached an impasse on the
    amount of fees Sanders should receive in the Ambrose case.   Olsman
    disavowed any agreement to pay Sanders any fee in the Greer and
    Holtquist cases and informed Sanders that he would not be allowed
    to perform any legal work on those pending cases.   More than a year
    later, the Greer and Holtquist cases settled, and OGM recovered
    attorneys fees in both cases.
    II.
    Sanders filed this lawsuit against OGM seeking recovery of his
    share of attorneys fees in the Ambrose, Greer, and Holtquist cases
    on several different theories, including breach of contract, quantum
    meruit, and unjust enrichment.   The district court granted summary
    judgment in favor of OGM on Sanders’ claim for attorneys fees in the
    Greer and Holtquist cases.   As for the breach of contract claims,
    the court ruled that the fee-sharing agreement between Sanders and
    OGM violates two provisions of Rule 1.5(e) of the Maryland Lawyers
    7
    Rules of Professional Conduct (MLRPC) because (1) Sanders failed to
    notify the Greers and the Holtquists that he would be performing
    legal work on their cases; and (2) Sanders’ work on those cases was
    not proportionate to the one-third fee that he would receive under
    the fee-sharing agreement.    The district court further found that
    OGM was entitled to the protection of a Maryland equitable defense
    to the contract claims.    Accordingly, the district court declared
    the fee-sharing agreement between OGM and Sanders unethical and
    unenforceable.   The district court also ruled that Sanders’ quantum
    meruit and unjust enrichment claims failed because Sanders did not
    perform any work on the Greer and Holtquist cases.
    Sanders’ claim for fees in the Ambrose case was tried to a jury
    on two alternative theories, breach of contract and quantum meruit.
    The district court instructed the jury to award Sanders “the fair
    value of the services rendered” by him.    The jury awarded Sanders
    $300,000.    OGM filed a post-trial motion for judgment as a matter
    of law.     Although the district court concluded that Sanders had
    presented sufficient evidence to prevail on the issue of liability,
    it granted OGM’s motion as to damages, concluding that Sanders had
    failed to present “evidence from which a reasonable jury could
    determine with any reasonable degree of certainty the fair value of
    his services in any amount in excess of” the $20,000 the Nashville
    law firm had already paid to Sanders.     Based on its ruling that
    8
    Sanders proved liability but not damages, the district court awarded
    Sanders nominal damages of $1.     This appeal followed.

    In a diversity action, state law of the forum court governs
    substantive issues, and federal law governs procedural issues.
    Dixon v. Edwards, 
    290 F.3d 699
    , 710 (4th Cir. 2002).            Accordingly,
    we apply the law of Maryland to determine the substantive issues in
    this appeal.
    We review the district court’s grant of judgment as a matter
    of law de novo.    Corti v. Storage Tech. Corp., 
    304 F.3d 336
    , 341
    (4th Cir. 2002). In conducting our review, we view the evidence and
    the   reasonable   inferences   drawn    therefrom   in   the    light   most
    favorable to the nonmoving party.        G.D.C., Inc.,

    Judgment as a matter of law is appropriate only when “there is no
    legally sufficient evidentiary basis for a reasonable jury to find
    for that party on that issue."     Fed. R. Civ. P. 50(a).
    We also review de novo the district court's grant of summary
    judgment.    Staples, Inc., 
    372 F.3d at 667
    .          “In reviewing the
    evidence, the court must draw all reasonable inferences in favor of
    the nonmoving party and may not make credibility determinations or
    weigh the evidence.”    
    Id.
         Summary judgment is appropriate only
    when there is no genuine issue of material fact and the moving party
    9
    is entitled to judgment as a matter of law.   Edell & Assocs. v. Law
    Offices of Peter G. Angelos, 
    264 F.3d 424
    , 436 (4th Cir. 2001).
    IV.
    We first address the district court’s grant of judgment as a
    matter of law in favor of OGM on Sanders’ claim for attorneys fees
    in the Ambrose case.      Because OGM has not cross-appealed the
    judgment for Sanders as to liability, the only issue before us is
    whether, under either a breach of contract or quantum meruit theory,
    there is a legally sufficient evidentiary basis for the jury’s
    conclusion that Sanders is entitled to $300,000 in fees.
    Under Maryland law, recovery in quantum meruit2 is based on the
    amount that the parties intended as the contract price or, if that
    amount is not expressed, “the fair market value of the plaintiff's
    services.”   Mogavero v. Silverstein, 
    790 A.2d 43
    , 53 (Md. Ct. Spec.
    App. 2002); see also Houston v. Monumental Radio, Inc., 
    148 A. 536
    ,
    543 (Md. 1930) (noting that under an implied-in-fact contract
    2
    Under Maryland law, a quantum meruit claim based on an
    implied-in-fact contract is an alternative to recovery based on
    breach of an express contract. See Alternatives Unlimited, Inc. v.
    New Baltimore City Bd. of Sch. Comm’rs, 
    843 A.2d 252
    , 295 (Md. Ct.
    Spec. App. 2004). We choose to base our opinion on Sanders’ quantum
    meruit cause of action because we question whether the parties’
    agreement to share fees based on the “totality of the
    circumstances” is sufficiently definite to be an enforceable
    express contract under Maryland law. See Peoples Drug Stores v.
    Fenton Realty Corp., 
    62 A.2d 273
    , 276 (Md. 1948).       Because we
    conclude that the jury verdict can be sustained under quantum
    meruit, we need not decide the breach of contract issue.
    10
    appellant     was     entitled   to   the   "reasonable   worth   of   [his]
    services”).3        Moreover, when a plaintiff is employed to perform
    specified work, he is entitled to recover in quantum meruit the
    value of his time and effort without reference to the benefit or
    advantage actually conferred on the defendant. Mogavero, 
    790 A.2d at 53
    .
    The parties do not dispute that the total attorneys fees of
    more than $1 million is a reasonable fee award in the Ambrose case.
    The district court informed the jury of this amount, and the jury
    was never instructed that it could question the reasonableness of
    these fees.    In essence, the jury was instructed to consider this
    total fee as the reasonable value for the amount of time and effort
    expended by all of the attorneys who performed legal work on behalf
    of the Ambroses. The question in this case thus becomes what is the
    fair market value of Sanders’ time and effort compared to the time
    and effort of all the other attorneys who represented the Ambroses.
    3
    Maryland law distinguishes between two types of quantum
    meruit claims, one based on an implied-in-fact contract (usually
    designated as quantum meruit) and the other based on an implied-in-
    law contract (usually designated as unjust enrichment). Mogavero,
    
    790 A.2d at 52-53
    . One of the primary differences between the two
    claims is the proper measure of damages.      Unjust enrichment is
    measured by the gain bestowed on the defendant, while quantum
    meruit is measured by the reasonable value of the work performed by
    the plaintiff. 
    Id.
     Although Sanders’ complaint and papers refer
    to both quantum meruit and unjust enrichment, the case was tried to
    the jury and argued to this court as a quantum meruit claim, so we
    decline to consider any potential unjust enrichment claim for fees
    in the Ambrose case.
    11
    Viewed in the light most favorable to Sanders, the evidence
    showed   that   Sanders’   “time,   energy   and   effort”   constituted
    approximately fifty percent of the total legal services performed
    by all the attorneys on behalf of the Ambroses.          Based on this
    evidence, the jury could reasonably find that Sanders was entitled
    to at least $500,000 of the more than $1 million awarded for
    attorneys fees in the Ambrose case.      Thus, we conclude that there
    is sufficient evidence from which a jury could find that the
    reasonable value of the services rendered by Sanders, compared with
    the work performed by the other lawyers, was at least $300,000.4
    Accordingly, we reverse the district court’s grant of judgment as
    a matter of law in favor of OGM.
    V.
    We next review the district court’s grant of summary judgment
    in favor of OGM on Sanders’ claims of breach of contract and quantum
    meruit and unjust enrichment as to the Greer and Holtquist cases.
    4
    The jury was not required to articulate how it reached its
    award. It is sufficient for our review that the jury could have
    awarded an even greater amount.
    12
    A.
    Although OGM denies that it ever contracted to pay any fees to
    Sanders in the Greer and Holtquist cases,5 the evidence, when viewed
    in the light most favorable to Sanders, shows that OGM agreed to pay
    Sanders a one-third fee and to allow him to perform legal work in
    both cases.   Assuming for purposes of summary judgment that the
    contract existed, OGM raised MLRPC 1.5(e) as a defense, asserting,
    in effect, that it would be inequitable for its alleged agreement
    with Sanders to be enforced.    The district court granted summary
    judgment by determining, as a matter of law, that the agreement made
    by OGM and Sanders was a “clear and flagrant” violation of MLRPC
    1.5(e), and that “non-enforcement of these invalid agreements would
    not lead to a ‘manifestly unjust or unfair’ result.”
    MLRPC 1.5(e) governs fee-sharing agreements.   It states:
    e) A division of fee between lawyers who are not in the
    same firm may be made only if:
    (1) the division is in proportion to the services
    performed by each lawyer or, by written agreement with
    the client, each lawyer assumes joint responsibility for
    the representation;
    (2) the client is advised of and does not object to
    the participation of all the lawyers involved; and
    (3) the total fee is reasonable.
    5
    On remand, OGM will be allowed to pursue this defense. If
    the factfinder determines that the parties never agreed to share
    fees in the Greer and Ambrose cases, then the issues regarding
    compliance with MLRPC 1.5(e) will become moot.
    13
    Under Maryland law, the MLRPC “constitutes an expression of public
    policy having the force of law.” Post v. Bregman, 
    707 A.2d 806
    , 816
    (Md.   1998).    MLRPC   1.5(e)   “is   not   limited   to   disciplinary
    proceedings.    It may extend to holding fee-sharing agreements in
    clear and flagrant violation of Rule 1.5(e) unenforceable.”        Id. at
    818.   A violation of MLRPC 1.5(e) is not, however, a per se defense
    to the enforceability of a fee-sharing agreement.        Id. at 819.    A
    court may not invalidate a fee-sharing agreement merely because the
    agreement fails to comply with all the requirements of MLRPC 1.5(e);
    instead “[p]arties have the right to make their contracts in what
    form they please, provided they consist with the law of the land;
    and it is the duty of the courts so to construe them, if possible,
    as to maintain them in their integrity and entirety.” Id. (quoting
    Webster v. People’s Loan, Sav. & Deposit Bank, 
    152 A. 815
    , 817 (Md.
    1931)).   Thus, instead of a per se defense, Rule 1.5(e) is “in the
    nature of an equitable defense, and principles of equity ought to
    be applied.”    Post v. Bregman, 707 A.2d at 819.       A court must not
    declare invalid a fee-sharing agreement for violations “that are
    merely technical, incidental, or insubstantial or when it would be
    manifestly unfair and inequitable not to enforce the agreement.”
    Id.    When a party raises this defense, the court must review the
    totality of the circumstances to determine whether (1) MLRPC 1.5(e)
    has actually been violated and, if so, (2) whether seven specified
    14
    factors militate in favor of declaring the agreement unenforceable.
    Id.
    Based on this test, we must first decide whether the parties’
    fee-sharing agreement violates MLRPC 1.5(e).          Under MLRPC 1.5(e),
    an oral fee-sharing agreement is valid only if: (1) the division of
    labor is in proportion to the services performed by each lawyer;
    (2)   the   client   is   advised   of   and   does   not   object   to   the
    participation of the lawyers who have agreed to share fees; and (3)
    the total amount of attorneys fees is reasonable.           The third factor
    is not at issue, because the parties agree that the total attorneys
    fees in the Greer and Holtquist cases are reasonable.
    As for the first factor, whether the division of labor is
    proportionate with the services performed by each lawyer, Sanders
    contends that OGM deprived him of the opportunity to participate in
    the cases when it disavowed the fee-sharing agreement and prohibited
    him from working on the Greer and Holtquist cases.6            The argument
    necessarily follows that OGM, as the breaching party, cannot assert
    Sanders’ failure to perform approximately one-third of the legal
    work on those two cases.      We agree.
    6
    Sanders also argues that he indirectly worked on the Greer
    and Holtquist cases while he was working on the Ambrose case
    because all three cases were similar. Even if we agreed that
    Sanders worked on the Greer and Holtquist cases, there is no
    evidence in the record showing that his participation was
    proportionate with the agreed one-third fee.
    15
    Because Sanders recommended Mueller to the Greers and the
    Holtquists, OGM agreed to share one-third of its fees with Sanders
    and also agreed that Sanders would be allowed to work on the two
    cases.   Because OGM thereafter repudiated the agreement, depriving
    Sanders of the opportunity to perform any work on the two cases, OGM
    is estopped from asserting that Sanders failed to perform his
    required proportionate share of the work to satisfy MLRPC 1.5(e)(1).
    See Parker v. Columbia Bank, 
    604 A.2d 521
    , 531 (Md. Ct. Spec. App.
    1992) (Motz, J.) (stating that Maryland law “prohibits one party to
    a contract from acting in such a manner as to prevent the other
    party from performing his obligations under the contract.”); see
    also Edell & Assocs., 264 F.3d at 444.
    The second factor is whether the client was advised of and did
    not object to the participation of Sanders as a lawyer in the case.
    In his deposition, Sanders testified that he told Mr. Greer that he
    was working on his case.   Sanders also testified that he believed
    he “must have discussed” the fact of his participation in the case
    with Mr. Holtquist.   From this evidence, a reasonable jury could
    find that Sanders informed the two clients that he would be working
    on their cases.    Also, there is no evidence in the record that
    either the Greers or Holtquists objected to Sanders’ participation.
    Thus, when viewed in the light most favorable to Sanders, a
    reasonable jury could find that the fee-sharing agreement entered
    into by OGM and Sanders did not violate either of the two factors
    16
    in dispute. The evidence shows that a fee-sharing agreement existed
    and that OGM’s breach of that agreement kept Sanders from performing
    a proportionate share of the work to justify the one-third fee, so
    that OGM is estopped from asserting otherwise.         The evidence also
    shows that the Greers and Holtquists were informed of Sanders’
    participation, and there is no evidence that they objected. Because
    a reasonable jury could find that MLRPC 1.5(e) was not violated, the
    district court’s grant of summary judgment in favor of OGM on
    Sanders’ breach of contract claim must be reversed.
    Even if we were to find that the fee-sharing agreement violated
    MLRPC 1.5(e), we would nonetheless reverse summary judgment because
    there is evidence, when viewed in the light most favorable to
    Sanders, that would make several, if not all, of the enumerated
    factors of the equitable defense militate in favor of enforcing the
    fee-sharing agreement.7      See In re Apex Express Corp. v. The Wise
    Co., 
    190 F.3d 624
    , 636 (4th Cir. 1999)(reversing summary judgment
    because   genuine   issues   of   material   fact   existed   relating   to
    equitable defenses).    Once a court determines that the fee-sharing
    agreement violates MLRPC 1.5(e), it must also consider the following
    seven factors to decide, based on equitable principles, whether the
    agreement should not be enforced:
    7
    Sanders also argues that the district court improperly placed
    on him the burden of proof as to the equitable defense raised by
    OGM. We leave this issue to the district court to decide in the
    first instance on remand.
    17
    (1) the nature of the alleged violation, (2) how the
    violation came about, (3) the extent to which the parties
    acted in good faith, (4) whether the lawyer raising the
    defense is at least equally culpable as the lawyer
    against whom the defense is raised and whether the
    defense is being raised simply to escape an otherwise
    valid contractual obligation, (5) whether the violation
    has some particular public importance, such that there is
    a public interest in not enforcing the agreement, (6)
    whether the client, in particular, would be harmed by
    enforcing the agreement, and, in that regard, if the
    agreement is found to be so violative of the Rule as to
    be unenforceable, whether all or any part of the disputed
    amount should be returned to the client on the ground
    that, to that extent, the fee is unreasonable, and (7)
    any other relevant considerations.
    Post v. Bregman, 707 A.2d at 819.     There is evidence, for example,
    that would firmly establish the fourth factor -- perhaps the most
    important of the seven factors -- in favor of Sanders.    The fourth
    factor requires the court to consider “whether the lawyer raising
    the defense is a least equally culpable [for the violation] as the
    lawyer against whom the defense is raised and whether the defense
    is being raised simply to escape an otherwise valid contractual
    obligation.”    Id.   Sanders has produced evidence that OGM was at
    least as culpable, if not more so, for the alleged violations of
    MLRPC 1.5(e).   As for failing to inform the Greers and Holtquists
    of Sanders’ participation, OGM had the same opportunity, if not
    more, to inform them but declined to do so.     OGM was lead counsel
    on the cases and had much more contact with the clients.     OGM had
    a written contract with the Greers and the Holtquists, which
    specifically allowed OGM to hire counsel to assist on the case.    A
    reasonable factfinder could deem OGM more culpable than Sanders for
    18
    failing to inform the clients about Sanders’ proposed participation.
    As for the other alleged violation, the lack of proportionate work,
    Sanders produced evidence that he was ready and eager to work on the
    cases but OGM prohibited him from participating after the fee
    dispute in Ambrose arose. Also, Sanders’ evidence suggests that the
    main reason that OGM is now raising the equitable defense of MLRPC
    1.5(e) is to keep it from having to pay Sanders the fees it promised
    to pay him in the Greer and Holtquist cases. Because genuine issues
    of material fact exist as to whether the seven factors militate in
    favor of declaring the fee-sharing agreement unenforceable, the
    district court’s grant of summary judgment must be reversed.    See
    Edell & Assocs., 264 F.3d at 442-43 (“Of course, the nature of [the]
    ethical considerations would require a jury to resolve factual
    issues raised by those considerations before actually considering
    the merits of the defense” of MLRPC 1.5(e)).
    B.
    Last, we affirm the district court’s grant of summary judgment
    on Sanders’ quantum meruit and unjust enrichment claims in the Greer
    and Holtquist cases.   Sanders has failed to produce any evidence
    that he worked directly on the Greer and Holtquist cases. Moreover,
    although Sanders argues in a conclusory fashion that his work on the
    Ambrose case would have benefitted the prosecution of the Greer and
    Holtquist cases, he has failed to produce any concrete evidence that
    19
    his work on the Ambrose case would have had any direct relevance to
    the specific issues and claims in the Greer and Holtquist cases.
    VI.
    For the foregoing reasons, we reverse the district court’s
    grant of judgment as a matter of law in the Ambrose case and its
    grant of summary judgment on the breach of contract claims in the
    Greer and Holtquist cases.   We affirm the district court’s grant of
    summary judgment in favor of OGM on Sanders’ quantum meruit and
    unjust enrichment claims in the Greer and Holtquist cases.
