    BLACKHAWK HEATING & PLUMBING CO., INC., and Andrew Machata, Appellants, v. DATA LEASE FINANCIAL CORPORATION, Appellee.
    No. 73-278.
    District Court of Appeal of Florida, Fourth District.
    Dec. 14, 1973.
    Rehearing Denied Jan. 16, 1974.
    John A. Gentry, III, of Moyle, Gentry, Jones & Flanigan, West Palm Beach, and Richard Joseph Brennan and Edward J. Wendrow of Winston & Strawn, Chicago, for appellants.
    Robert T. Scott, Palm Beach, for appel-lee.
   PER CURIAM.

The trial court denied specific performance and plaintiffs appeal. We have reviewed the final judgment in light of the excellent appellate presentations and thereby conclude that there has been no demonstration of reversible error. The critical decisions that the contract terms were vague and uncertain and that the option had not been properly exercised find adequate competent support in the record, Finding no error of law or otherwise, the judgment is

Affirmed.

OWEN, C. J., WALDEN, J., and GONZALEZ, JOSE A., Jr., Associate Judge, concur.
