The Rights Holder named above is entitled to acquire one Class B Subordinated Beneficiary Interest (a "Class B Subordinated Interest") in AFG Investment Trust B (the "Trust") for each Right held. Please Note: Minimum subscription is the lesser of (a) the amount of Class B Subordinated Interests which the Rights Holder is permitted to acquire, which is equal to the number of Rights set forth above, or (b) 400 Class B Subordinated Interests for IRAs or other Qualified Plans or (c) 1,000 Class B Subordinated Interests for all other subscribers (with a higher minimum purchase in certain states). To subscribe for Class B Subordinated Interests, the Exercising Rights Holder must present to Gemisys Corporation (the "Subscription Agent"), prior to 5:00 p.m., Boston time, on July 15, 1997 unless extended by the Trust (the "Expiration Date"), at the address set forth on the reverse side of this Certificate: a properly completed and executed Subscription Certificate and a money order or check drawn on a bank located in the United States and payable to Trust Company of America, as agent for the Trust, in the amount of the Subscription Price for the number of Class B Subordinated Interests subscribed for under his or her Basic Subscription Rights. The Subscription Price for the number of Class B Subordinated Interests, if any, for which the Over-Subscription Privilege is being exercised is payable as set forth below. If the Rights Holder subscribes for additional Class B Subordinated Interests pursuant to the Over-Subscription Privilege, Part B of Section I of this Subscription Certificate must be completed to indicate the maximum number of Class B Subordinated Interests for which the Over-Subscription Privilege is being exercised. Immediately following the Expiration Date, the Subscription Agent will notify each Exercising Rights Holder (or, if the Trust's Class A Interests are held by a nominee, such nominee) as to the number of Class B Subordinated Interests purchased pursuant to his or her Basic Subscription Rights and, if applicable, pursuant to the Over-Subscription Privilege, explaining the allocation of Class B Subordinated Interests pursuant to the Over- Subscription Privilege. The Subscription Agent will also indicate whether or not the Special Beneficiary and its Affiliates have obtained voting control of the Trust through their purchases of Class B Subordinated Interests, and, if such control had been obtained, the Exercising Rights Holder will have the opportunity to revoke his or her subscription in whole or in part. No later than 3 business days following such notice from the Subscription Agent, the Exercising Rights Holder (unless such Rights Holder has elected to revoke his or her subscription) must remit to the Subscription Agent a money order or check drawn on a bank located in the United States and payable to Trust Company of America in the amount of the Subscription Price for the number of Class B Subordinated Interests purchased by him or her pursuant to the Over-Subscription Privilege. All payments tendered in connection with the exercise of Basic Subscription Rights by Exercising Rights Holders who subsequently revoke their subscriptions will be refunded by mail as promptly as practicable after the Expiration Date. If an Exercising Rights Holder does not make payment of any amounts due in respect of Class B Subordinated Interests subscribed for, the Trust and the Subscription Agent reserve the right to (i) find other Rights Holders for the subscribed and unpaid for Class B Subordinated Interests; (ii) apply any payment actually received by it toward the purchase of the greatest whole number of Class B Subordinated Interests which could be acquired by such Holder upon exercise of his or her Basic Subscription Rights and/or pursuant to the Over-Subscription Privilege, and/or (iii) exercise any and all other rights and/or remedies to which it may be entitled, including, without limitation, the right to set-off against payment actually received by it with respect to such subscribed Class B Subordinated Interests.
