Earlier this week we wrote about how some directors of The First Marblehead Corporation, who were also large shareholders, were feeling the financial pain of the company’s recent stock swoon.

The company, and the directors, got some relief Friday from Goldman Sachs, which agreed to invest up to $260.5 million in the Boston-based packager of student loans.

It has been an especially tough couple weeks for Leslie Alexander, the largest shareholder of The First Marblehead Corporation, a packager of student loans.

Alexander owns the Houston Rockets of the NBA. He also controls more than 18.2 million shares of First Marblehead stock.
