Company officials said it will issue 6.3 million shares of stock for all the shares of SupplierMarket.com, a privately held company that registered in March with the Securities and Exchange Commission for an initial public offering.
SupplierMarket.com helps buyers and suppliers of direct and indirect materials locate new trading partners, negotiate purchases and collaborate on the Internet.

Harmonic shares should slip after it warned of lower-than-expected earnings in its second quarter.
It's now expecting a profit of between 12 cents to 14 cents a share, woefully short of the consensus estimate of 29 cents a share.
The communications equipment maker said sales will lumber in at $74 million to $82 million mainly because sales to AT&T (NYSE: T) have dried up.

"Early in the quarter, new advanced software features were incorporated into the company's then current software release," the company said in a prepared release.

Last quarter, Network Peripherals lost $3.8 million, or 28 cents a share, on sales of $3.3 million.
Its shares surged to a 52-week high of 79 in February after falling to a low of 15 5/16 in September.
