Before RICHARD S. ARNOLD, FAGG, and HANSEN, Circuit Judges.

PER CURIAM.




                                          -2-
       Roeles Ortiz, Sean Demarco Stone, Eric Gabriel Ortiz, and Ramon Ortiz, Jr.
(collectively Appellants) appeal the district court's adverse rulings on their motions for
new trial and to vacate their sentences. We affirm.

       The Appellants raise several contentions in support of their claims for a new trial
and for correction of their sentences. Having reviewed the record, we reject their
arguments. We agree with the district court's conclusions that, first, the newly
discovered exculpatory evidence the government failed to disclose would not likely
produce an acquittal if a new trial were granted or provide a basis to correct the
Appellants' sentences, and second, because the withheld evidence does not undermine
confidence in the verdicts and the sentences, the evidence does not satisfy the
materiality requirement under Brady v. Maryland, 

, 87 (1963). We also
conclude the district court's sentence-related factual findings about drug quantities and
roles in the offenses are not clearly erroneous, the district court properly imposed a
weapons enhancement, and the district court neither violated nor misapplied the
sentencing guidelines. We are satisfied the district court properly denied the
Appellants' motions for a new trial and to vacate their sentences, the appeal simply
involves the application of settled principles of law to unique facts, and the issues do
not warrant a comprehensive opinion. We thus affirm the district court without further
discussion. See 8th Cir. R. 47B.

             Attest:

                     CLERK, U.S. COURT OF APPEALS, EIGHTH CIRCUIT.
