United Concrete Pipe Corporation, Petitioner v. Spin-Line Company, Inc., Respondent

Summary

The Texas Supreme Court held that the agreement between United Concrete Pipe and Spin-Line was validly accepted on January 10, 1964, that the deletions and wording changes in the agreement were not material alterations, and that such non‑material changes, even if beneficial to the surety, do not discharge the endorsers from liability. Accordingly, the court affirmed the judgments against Spin-Line and S. Mort Zimmerman and reversed the portion of the lower judgment favoring the other endorsers.
