| Hitachi Cable has long been committed to environmental protection as a major element of its corporate management strategy. Here we will explain some of our activities: environment-friendly products and technologies, for example (including those involving wires and cables), as well as green procurement activities designed to comply with the RoHS Directive. |

| Hitachi Cable's ECO-GREEN® cables emit no toxic gases — including halogen, hydrogen chloride, and dioxin — when they are burned. Burying the cables poses no danger of the release of lead or other heavy metals. ECO-GREEN® cables will emit no toxic substances in any environment; this is the major strength of this series. |
|
| This outstanding feature was achieved through an advanced material processing technique in which materials such as polyolefin resins and metal hydroxides are blended. We now offer a wide assortment of products based on these proprietary technologies. Consumers of our cost-effective products include government agencies and local municipalities promoting the creation of "green " government offices, as well as schools and private companies. In addition, we are vigorously working to develop high-quality and high-value-added products that take workplace efficiency into account. In cable development, for example, we have successfully reduced the friction resistance of cable insulation, increasing flexibility and minimizing whitening and surface roughness. |

| Following a number of fire-related accidents that occurred in power facilities and telephone stations in the 1980s, Hitachi Cable began to develop cables that would have no adverse effect on people or on the environment even when burned. In 1984, we launched a lineup of halogen-free cable products. Conventional halogen-free flame-retardant polyolefin insulators are not suitable for high-speed signal transmission cables due to their high permittivity. To overcome this problem, we developed an aromatic halogen-free flame-retardant polymer composite that is flame-retardant while offering superior electrical properties with lower permittivity. In 1996, we commercialized our halogen-free highly flame-retardant LAN cables capable of carrying high-speed digital signals of 10 to 100Mbps. |

| "Outgas " refers to molecular contaminants emitted from various materials. These contaminants are classified into organic substances, acid gases, basic gases, and dopant compounds. Under this classification, cables are considered a source of organic substances. Gaseous organic substances emitted from cables adhere to semiconductor wafers, affecting the electrical insulation of the gate oxide films or contaminating exposed lenses. These substances have posed a problem in semiconductor manufacturing facilities and the like, where extremely high levels of cleanliness are required. |
|
| Hitachi Cable modified its materials and manufacturing process to develop an environment-friendly low outgas PVC cable that offers excellent manageability and contains no lead or other heavy metals. We introduced this cable to the market in January 2003. Thanks to its reduced outgas values?approx. one-thousandth those of our conventional products?this cable is receiving widespread attention as an ideal wiring material not only for leading-edge electronics manufacturing facilities producing semiconductors or LEDs, but also for advanced medical devices, where high levels of cleanliness are essential. |
