The mark consists of the word "VOLTERA" using capitalized letters of a stylized font wherein the horizontal sections of the letters "E" and "A" and the lower portion of the circular section of the letter "R" are separated from the left part of those letters. Beneath the word "VOLTERA" are five equally sized and equally spaced rectangles shaded from darkest to lightest. The color white in the mark merely represents transparent background and is not claimed as a feature of the mark.
