We propose to observe the first gamma-ray emitting z>3 BL Lac object, 4FGLJ1219.0+3653 (z=3.59), for 50 ksec with EPIC-PN CCD on XMM-Newton. It is theonly spectroscopically confirmed BL Lac source beyond z=3. However, this sourcehas no previous X-ray spectral measurements. The XMM observations will allow usto characterize the X-ray spectral behavior of the source which will enables usto accurately determine the associated jet power and the particle populationresponsible for the observed emission. We will compare the derived results withother gamma-ray emitting z>3 flat spectrum radio quasars.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
