said right of exercise (the "Right of Acceleration"), on the sole condition that

Acceleration at any time or times on or before the date of the closing of any
transaction referred to in (i), (ii) or (iii) of this Section 6(c), or at any

Option Shares with respect to which the option is being exercised, together with
payment of the Exercise Price therefor. The Exercise Price may be paid in cash

such other manner as Company may permit. Upon the exercise of the option in
accordance with this Agreement and collection of the Exercise Price, Company
shall deliver to Employee a certificate or certificates for the Option Shares;
provided, however, that the time of such delivery may be postponed by Company
for such period as may be required for it with reasonable diligence to comply

such Option Shares pursuant to any cashless exercise program approved by the
Company.
