Exhibit 99.1

Employment Arrangements with Brooks

      Upon the consummation of the merger, five current Helix executives, including Messrs. Gentilcore and Anastasi, will be appointed to designated positions at Brooks. Mr. Gentilcore will be appointed Brooks’ President and Chief Operating Officer, Semiconductor Products Group and Mr. Anastasi will be appointed Brooks’ Executive Vice President, Global Operations.

      Brooks has entered into agreements with these Helix executives which will become effective upon consummation of the merger, including an employment agreement, an indemnification agreement and an invention, non-disclosure, non-competition, non-solicitation agreement. These agreements will replace in their entirety the current agreements that these executives have with Helix, if any.

      Each employment agreement provides for, among other things, an annual base salary of $375,000 for Mr. Gentilcore and $290,000 for Mr. Anastasi, and an annual management bonus of 0% to 150% of 100% of base salary for Mr. Gentilcore and 0% to 150% of 70% of base salary for Mr. Anastasi. During the first year of employment, the employee will be eligible to participate in the current Helix benefit plans. Subsequently, the employee will be eligible to participate in all benefits normally offered to senior executives of Brooks. Mr. Gentilcore and Mr. Anastasi will receive options to purchase 25,000 shares and

15,000 shares, respectively, of Brooks common stock, which will vest quarterly over four years. Also, Mr. Gentilcore and Mr. Anastasi will receive grants of 12,500 shares and 7,500 shares, respectively, of restricted Brooks common stock, 25% of which will vest after each of the first two years and the remaining 50% of which will vest after the third year. Each agreement also provides that the employee will be entitled to severance including one year’s base salary and continued participation in benefit plans if terminated without “cause” or if the employee resigns for “good reason.” Cause is defined to include willful failure or refusal to perform the duties pertaining to the employee’s job, engagement in conduct that is fraudulent, dishonest, unlawful or otherwise in violation of Brooks’ standards of conduct or a material breach of the employment agreement or related agreements. Good reason is defined to include diminution of the responsibility or position of the employee, Brooks’ breach of the agreement, relocation of the employee more than 60 miles from Mansfield, Massachusetts or the Chelmsford, Massachusetts area if he relocates his primary residence to the Chelmsford area. In the case of Mr. Gentilcore, good reason also includes Brooks’ failure to offer him the position of Chief Executive Officer upon conclusion of the term of office of the Chief Executive Officer serving on the closing date of the merger. Payment of base salary and continued participation in benefit plans may be extended for up to one additional year if the employee is engaged in an ongoing search for replacement employment. Each employee will also be eligible for reimbursement of up to $100,000 in relocation expenses.

      The indemnification agreements provide that Brooks will indemnify an individual to the fullest extent permitted by applicable law in connection with any civil or criminal action or proceeding, including actions by or in the name of Brooks, where the individual’s involvement is by reason of the fact that he was serving on behalf of Brooks. This indemnification covers attorney’s fees, judgments, civil or criminal fines, settlement amounts, and other expenses customarily incurred in connection with legal proceedings. Under the indemnification agreements, an individual will receive indemnification unless he or she is found not to have acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of Brooks. The indemnification agreements also cover other matters pertaining to indemnification, including circumstances when indemnification is due with respect to some claims but not others, indemnification for service as a witness, advancement of expenses and various procedural matters.

      The invention, non-disclosure, non-competition and non-solicitation agreements provide that the employee will disclose and assign to Brooks all inventions, discoveries, trade secrets and improvements developed or made by the employee during his employment with Brooks and assist with obtaining and enforcing patent, copyright and other forms of related legal protection. The agreements provide that the employee will not disclose any information relating to such inventions or other confidential information received by the employee during his employment at Brooks. The agreements also prohibit the employee from directly or indirectly competing with, or soliciting employees of, Brooks so long as he is an employee of Brooks and for a period of one year thereafter.
