Twenty-four-year-old Caprice (pictured below) has agreed a two-year deal with the O’s, and arrives at the Matchroom Stadium after leaving new league rivals Woking.
Having started out in the youth ranks at Crystal Palace, Caprice signed his first professional contract with the Eagles in 2011, though was unable to make the breakthrough at Selhurst Park and signed for Blackpool a year later.
The defender was unable to make his mark at Bloomfield Road, however, as he found his opportunities limited before making his professional debut whilst on loan at Dagenham & Redbridge in December 2012.
The 2013/14 campaign also saw the defender head out on loan, first to Scottish side St Mirren before ending the season with National League North outfit Tamworth.
Following two seasons at Blackpool, Caprice then completed a switch to Lincoln City in August 2014, and quickly became a consistent figure for the Imps as he racked up a total of thirty-seven appearances throughout the 2014/15 season.
After impressing during that season at Sincil Bank, the defender found himself on the move again by agreeing a pre-contract with Woking ahead of the 2015/16 campaign.
The pacey Caprice wasted little time in making the right-back spot his own, and during his two seasons with the Cards made a total of eighty-nine appearances.
Lee, 30, joins after leaving Sky Bet League Two outfit Stevenage, and has signed a two-year deal in E10.
A graduate of the Tottenham Hotspur youth system, Lee signed his first professional contract with the North Londoners in 2005, although was unable to make the breakthrough at White Hart Lane before moving to Peterborough United in 2007.
The move to London Road would provide Lee with both first real taste of consistent first-team football and success, as the midfielder scooped the player of the year award in successive seasons to help Posh reach the Championship with back-to-back promotions in both 2007/08 and 2008/09.
Lee went on to make a total of 177 appearances for Peterborough, before leaving in 2011 to join Gillingham following a successful loan.
Whilst with the Gills, the midfielder would go on to experience the third promotion of his career the Kent side finished the 2012/13 season as champions of League Two.
Comfortable playing in midfield and at left-back, Lee then made the switch to Stevenage in 2014, and chalked up 130 appearances during his three years at the Lamex Stadium.
