ANN ALDRICH, District Judge. Defendant Santiago Santillana (“Santillana”) appeals a sentence imposed after he pled guilty to two counts of using a firearm during, and in relation to, a drug trafficking offense in violation of 18 U.S.C. § 924(c). The district court sentenced Santillana to 84 months and 156 months to run consecutively, representing a downward departure of 144 months. Although Santillana does not challenge the reasonableness of this sentence, he does challenge the district court’s decision not to make a further downward departure. Because we generally do not review a district court’s decision not to depart downward, and because no exception to that rule applies here, Santillana’s sentence is affirmed.

SUTTON, Circuit Judge. At stake in this case is the enforceability of a “gold clause” contained in a 1912 lease agreement.

Either way, in light of this ruling, the parties now know one of the effects of the 1982 assignment. By March 31, 2011, S&R will decide whether it wishes to exercise its option to renew the lease. In the interim, the case needs to be remanded to the district court. Because the court found that the gold clause was not enforceable under the 1933 statute, it did not reach the question of the gold clause’s effect on the rent owed under the lease. Because we conclude that the clause is enforceable, we thus remand the case to the district court to interpret the clause, to determine the obligation it imposes on S&R and to address any other defenses the district court has not yet had an opportunity to address in the first instance, including S&R’s estoppel-by-deed and waiver defenses.

For these reasons, we reverse and remand for further proceedings.
