Service in a way or


                                       18


for any purpose that infringes or misappropriates any third party's copyrights,

      7.1 Compaq's Indemnities. Compaq agrees to indemnify and hold DoubleClick
and its Affiliates, officers, directors, employees and agents (each a
"DoubleClick Indemnitee") harmless from and against any and all claims, actions,
losses, damages, liability, costs and expenses (including, without limitation,
reasonable attorneys' fees and disbursements incurred by a DoubleClick
Indemnitee in any action between Compaq and the DoubleClick Indemnitee, or
between the DoubleClick Indemnitee and any third party or otherwise) arising out
of or in connection with any breach of any of Compaq's representations,
warranties or obligations set forth in this Agreement. DoubleClick shall
promptly notify Compaq of all claims and proceedings related thereto of which
DoubleClick becomes aware.

      7.2 DoubleClick's Indemnities. DoubleClick agrees to indemnify and hold
Compaq and its Affiliates, officers, directors, employees and agents (each a
"Compaq Indemnitee") harmless from and against any and all claims, actions,
losses, damages, liability, costs and expenses (including, without limitation,
