## EXHIBIT W - Retractable Roof Policy 

Whenever practical, playing conditions on the center court will remain the same as on all other courts. 

In the event rain is falling prior to the scheduled starting time of the match, the roof will remain closed for the duration of that match. 

If the rain stops and the forecast is good, the roof may be opened after the match in progress is completed. Decisions on re-opening the roof will be made on a match-by-match basis depending upon current conditions and the forecast. 

If play commences with the roof open, a decision to close the roof will normally be made after play has stopped because of rain, although if other factors warrant the roof to be closed prior to this, the Supervisor will make that decision. 

The roof will not normally be closed because of the threat of rain. 

In the event high winds, sufficient to harm the retractable roof, are forecast with reasonable certainty, the roof may be closed prior to the start of the match. The reverse is applicable when the roof is closed and high winds or other conditions necessitate, for safety reasons, that the roof be opened. 

In the event that the temperature is below 50F / 10C prior to the start of a match, in order to enhance the fan experience, the roof may be closed as directed by the Supervisor. Decisions on whether to close the roof for cold will be made on a match-by-match basis. 

In some instances, the roof must be partially closed for the lights to function prop - erly. In this case, the roof must be partially closed prior to the start of the match. 

The ATP Supervisor shall be the final authority on all decisions regarding the

## EXHIBIT X - Writing Table For Umpire Chairs 

In an effort to provide a comfortable platform for the Chair Umpires to place their hardware such as tablet, walkie-talkie, net device handset, it is requested that all tournaments attach a writing table according to the instructions below to the Chair Umpire’s chairs on all match courts. 

This simple and low cost upgrade will contribute tremendously to reduce scoring er - rors caused by data being accidentally entered as a result of the umpire holding the tablet in their hand and ease the process of entering data in the tablet. 

When setting up the writing tables, please make a note of the following: 

• Attach the writing table to the right side armrest. If there is a microphone attached to the chair, the microphone must be installed on the left side of the chair so as not to interfere with the writing platform on the right side armrest. 

• Ensure that the writing table is installed with the slender end at the back of the armrest. The design is made considering most armrests are 20 inches (50.8 cm) long and 3 inches (7.62 cm) wide. This design calls for the overall dimension of 32 inches (81.28 cm) which leaves a full 12 inches (30.48 cm) of space in front of the umpire for the various equipment. 

• A standard wood product could be used. For example, in the USA a 1 x 12 could be used and just cut to length and ripped for the 9 x 20 piece that is taken out. The actual dimension of a 1 x 12 is 11 ½ inches wide by ¾ inches thick. A comparable product could also be used in countries using the metric standard.
