      sixty (60) days from receipt of such notice so as to secure the conformity
      to VHS Standards and/or other quality requirements imposed by Licensor.

(4)   Even if Licensee does not manufacture magnetic tapes or component parts
      for Licensed Products but procures them for Licensee's manufacture of
      Licensed Products from any other licensee, Licensee shall confirm, as its
      own responsibility, that such magnetic tapes or component


                                      -11-

(6)   Upon Licensee's request and subject to Licensor's reasonable convenience,
      Licensor agrees to have a technical meeting with Licensee's engineer(s) to
      provide Licensee with technical counsel for the interpretation of
      Technical Information and the performance measurement of Licensed Products
      at Licensee's cost and expenses.
