SUPPLEMENT TO CARE AGREEMENT

               This Supplement to CARE Agreement is entered into as of September
22, 2000, and supplements the Agreement Among Rentrak  Shareholders  dated as of
May 24, 2000 (the "CARE Agreement"), among the shareholders (the "Shareholders")
named on Attachment A hereto.

               Because the  Shareholders  have  accomplished  their objective to
replace the incumbent  directors of Rentrak  Corporation and related matters set
forth in the CARE Agreement, the Shareholders now hereby agree as follows:

               1. An amended  Schedule 13D will be filed with the Securities and
Exchange  Commission  to report the  termination  of the CARE  Agreement and the
termination  of  "group"  status  within the  meaning  of  Section  13(d) of the
Securities Exchange Act of 1934 and the rules promulgated thereunder.

               2.  Effective  as of the date  first  set forth  above,  the CARE
Agreement  will  be  terminated  and  the  Shareholders  will  have  no  further
obligations  thereunder,  except that Paul  Rosenbaum is hereby  authorized  and
directed on behalf of the  Shareholders to arrange for the filing of the amended
Schedule 13D described  above promptly after the execution of this Supplement to
the CARE Agreement.

               3. The Power of Attorney signed by each  Shareholder  pursuant to
the CARE  Agreement will remain in effect as necessary or desirable to carry out
the intent and purposes of this Supplement to CARE Agreement.




               Paul A.  Rosenbaum  has duly  executed  this  Supplement  to CARE
Agreement on his own behalf and on behalf of each other Shareholder  pursuant to
an effective Power of Attorney as of September 22, 2000.
