Input:  Person1:     I'm pleased to meet you again , Mrs . King . 
 Person2:  Pleased to see you , too , Mr . Brown . 
 Person1:      You've had a good trip , I hope . 
 Person2:  Yes , a very pleasant journey , thank you . 
 Person1:      It's been a full two years since we last saw each other . 
 Person2:  So it is , I've come again to renew our sole agency agreement for another 2 years . 
 Person1:      We shall be pleased to talk the matter over with you . You've done very well in fulfilling the agreement . 
 Person2:  I'm glad you're satisfied with our work . I can assure you we've spared no effort and spent quite a sum of money in pushing the sales of your products . 
 Person1:      Yes , we appreciate your efforts in pushing the sales of our pianos . We can see you are experienced in this particular line . 
 Person2:  Thank you . 
 Person1:      But I think the annual sale of 300 pianos for a sole distributorship in Canada is rather conservative . After all , you sold around 400 pieces there last year . You can sell more this year according to the marketing conditions at your end . 
 Person2:  That is the result of our hard work . Well , what annual quantity would you suggest for the new agreement then ? 
 Person1:      500 pieces . 
 Person2:  No , no . That's too big a number to be acceptable . Let's put it at 450 pieces . And we'll strive to sell more , of course . We wish to add another clause . For every 50 pieces sold in excess of the quota , we'll get 1 % more in commission for our efforts . 
 Person1:      All right , let's fix it at 450 pieces then . And for every additional 50 pianos sold , we'll give you 1 % higher commission . 
 Person2:  I suppose all the other terms remain unchanged . 
 Person1:      We would like to make a specific mention of one more point . As our sole distributor , you will neither handle the same or similar products of other origins nor re-export our goods to any other area outside your own . 
 Person2:  No , certainly not . That's a reasonable restriction . 
 Person1:      Another thing is that every six months we would like to receive from you a detailed report on current market conditions and the users comments on our products . 
 Person2:  Yes , we've already prepared one . I've brought it with me . I'll put it forward when we talk with the manufacturers tomorrow . 
 Person1:      Good , that's all then . 
 Person2:  Good .
