         SANMINA'S GROWTH STRATEGY

- -        ENHANCED ABILITY TO MEET FUTURE CUSTOMER DEMANDS FOR INNOVATIVE,
         COST-EFFECTIVE TECHNOLOGY SOLUTIONS

Commenting on the merger, Jure Sola, Sanmina's Chairman and Chief Executive
Officer, said, "We are enthusiastic about our merger with Hadco, a leading
supplier of printed circuit boards in North America. Both companies provide
customers with cost-effective solutions and focus on advanced engineering design
and technology. We also share the same customer commitment to providing high-end
quality products, on-time delivery, and highly responsive customer service. The
merger with Hadco is a natural extension of our strategy to combine our printed
circuit board expertise with our other advanced manufacturing capabilities to
better serve the fast growing, high-end/low to medium volume electronics
manufacturing markets.

 "We believe our merger with Hadco clearly reflects an opportunity to grow our
business by satisfying the increasing demand for leading-edge interconnect
technology. Founded as a manufacturer of high-end printed circuit boards,
Sanmina has leveraged this technology to become one of the most successful
electronics contract service companies in the world. As a result of our
end-to-end solution capabilities, customer demand for our superior circuit
technology has been very strong, requiring increased capacity.

 "Importantly, the combination of our two companies enhances our ability to meet
the increasing demands by our telecommunications customers for advanced optical
networking technology. We believe this merger firmly establishes Sanmina as the
global leader in printed circuit board fabrication technology," Sola concluded.

Andrew E. Lietz, President and Chief Executive Officer of Hadco, said, "We are
very excited about this merger. Sanmina is a great company with a proven track
record in successfully meeting the demands of the rapidly growing EMS market. As
a result of the merger, we believe that Hadco's growth opportunities will
accelerate as we bring more value-added services to our clients. In addition,
the combined company will have increased leverage in material procurement and
supply chain management. We believe that the growth prospects for the combined
company are substantial and the business combination is in the best interests of
our employees, customers and shareholders."

Headquartered in Salem, New Hampshire, Hadco is the leading manufacturer in
North America of complex, multi-layer rigid printed circuit boards and
backplanes. The company has approximately 1.8 million square feet of engineering
design, printed circuit board fabrication and backplane assembly space located
in key regions throughout the U.S. and Malaysia. Hadco's customers are leading
electronic manufacturers in the communications, industrial automation, and
high-end computing industries. Clients include Sun Microsystems, Cisco, Lucent
and Nortel Networks.

The merger is subject to several conditions, including the approval of Hadco's
stockholders and the expiration of the waiting period under the federal
Hart-Scott-Rodino Antitrust Improvements Act. In the event that the Sanmina
share price falls below $40.00 per share based on the average closing stock
price over a 20 day period ending on the third trading day prior to the Hadco
stockholder meeting, the Hadco Board of Directors has the right, but not the
obligation, to terminate the definitive agreement. If this event were to occur,
Sanmina has the right to increase the exchange ratio such that each Hadco
