Revenues
TXP currently derives almost all of our revenue from our prototyping and material supply chain management services. Prototyping services are priced based on the complexity, time-to turn and volume of the customer project. TXP's material supply chain management services are priced at the cost of the material plus 5% to 25%. Revenues increased 480% from $1,032,000 in Q2004 to $5,989,000 in Q2005. Material supply chain management services decreased 39% from $460,000 in Q2004 to $281,000 in Q2005. Prototyping and assembly services decreased 18% from $572,000 in Q2004 to $471,000 in Q2005. Photonics Prototyping increased from $0 in Q2004 to $5,237,000 in Q2005. Photonics prototyping accounted for 87% of the overall increase in revenues. These revenues were from a single customer and represent a new revenue source for TXP as we expanded our offering in 2005 to include photonics prototyping.
