Plaintiff United States hereby certifies that it has complied with the provisions of Section 5 of the Clayton Act, as amended by Section 2 of the Antitrust Procedures and Penalties Act (codified at 15 U.S.C. §§ 16(b)-(h) ("Tunney Act")), and states:

1.	The proposed Final Judgment against Wind River Systems, Inc. was filed with the Court on June 21, 2002. 15 U.S.C. § 16(b).

2.	The proposed Final Judgment against The MathWorks, Inc. was filed with the Court on August 15, 2002. 15 U.S.C. § 16(b).

3.	The Competitive Impact Statement was filed with the Court on September 15, 2002. 15 U.S.C. § 16(b).

4.

5.	Pursuant to 15 U.S.C. § 16(b) the proposed Final Judgments and the Competitive Impact Statement were published in the Federal Register on October 21, 2002, at 67 Fed. Reg. 64657 (2002).

6.	A summary of the terms of the proposed Final Judgments and the Competitive Impact Statement were published in The Washington Post for seven consecutive days, from September 28, 2002, through October 4, 2002. 15 U.S.C. § 16(c).

7.	The 60-day period for public comments on the proposed Final Judgments, specified in 15 U.S.C. § 16(d), commenced on October 21, 2002 and expired on December 20, 2002.

8.	The United States received and responded to two comments on the proposed Final Judgments. The United States' response to the public comments, as well as the comments received, were filed with the Court on January 15, 2003, and published in the Federal Register on January 23, 2003, at 68 Fed. Reg. 3267 (2003). 15 U.S.C. § 16(d).

Pursuant to the Stipulations filed on June 21, 2002, and August 15, 2002, the Court may enter the proposed Final Judgments after it determines that the Judgments satisfy the public interest standard of 15 U.S.C. § 16(e). Plaintiff's Competitive Impact Statement and Response to Public Comments demonstrate that the proposed Final Judgments are in the public interest. Accordingly, Plaintiff requests that the Court enter the proposed Final Judgments without further hearings. Copies of the Wind River and The MathWorks Final Judgments are attached at Tabs 1 and 2, respectively.
