Corollary 3

Commutative Algebra, chapter X, § 4. Anneaux réguliers

Every finitely generated reflexive module over a regular noetherian local ring of dimension 2 is free.

In fact, a regular noetherian local ring is integrally closed (VIII, § 5, No. 2, cor. 1 of th. 1). Corollary 3 therefore follows from corollary 2 and § 1, No. 10, prop. 16.

Bourbaki puts the proof directly after the statement, so what is above is the statement and its proof together.
