When it looked like both would have settled down, they threw away their wickets.
Kotak, while trying to cut Harbhajan Singh, gave a simple catch to Mandeep Singh at first slip.
He made 54 with nine fours. Shah failed to clear his lofted shot off Bipul Sharma and was caught by Sandip Sharma at long on. He made 87.
The in-form Arpit Vasavada did not last long and was adjudged leg before off Kaul.
Jackson and Makwana then added 45 runs for the unbroken sixth-wicket partnership.
