Aug 17 (Reuters) -

Private equity group Advent International said on Sunday it

has agreed to take over Switzerland's U-Blox Holding in

a cash offer worth some 1.05 billion Swiss francs ($1.30

billion).

Advent said its public tender offer for U-Blox's shares

would be carried out by its indirect subsidiary ZI Zenith.

The 135 Swiss francs per share offer represents a 53%

premium to the undisturbed volume-weighted average share price

of the last six months, Advent said in a statement with U-Blox.

The tender offer is subject to terms and conditions, and

regulatory approvals customary for such transactions, and is

expected to be settled within the next six months, it added.

U-Blox, a maker of microchips and software for car

navigation, said on Friday it was in talks with Advent.

The Swiss technology group, which went public in 2007,

said last week it cut its first-half loss before interest and

tax to 7.7 million francs from a loss of 28 million a year

earlier.

Earlier this year, the firm sold a unit making cellular

modules for wireless communication to focus on navigation and

positioning technology used in cars, robots and farm equipment.
