                                                                     -----------


                                     FORM OF

                             SUBSCRIPTION AGREEMENT


     Subscription Agreement (this "Agreement"), made this __ day of __________,
2002 by and between Wentworth III, Inc., a Delaware corporation (the "Company"),
and ________________ (the "Subscriber", and collectively with all other entities
entering into subscription agreements for Shares, the "Subscribers"). In
consideration of the mutual promises and covenants herein contained, the parties
hereto (the "Parties") agree as follows:


                                   ARTICLE I.

                                  SUBSCRIPTION


     1.1. Subscription Offer. Subject to the terms and conditions hereof and to
acceptance by the Company, the Subscriber hereby offers to purchase _____ shares
(the "Shares") of the Company's common stock, par value $.01 per share (the
"Common Stock"), at a price per share of $1.00, for a total purchase price of
$__________ (the "Purchase Price"). Such offer can be revoked only upon written
notice by the Subscriber to the Company, which notice is received by the Company
prior to acceptance of the offer. The Purchase Price is payable in full by check
made payable to "Key Bank National Association, Wentworth III, Inc. Escrow
Account administered by Corporate Stock Transfer" and sent to Corporate Stock
Transfer, Inc., as Administrator for Wentworth III, Inc., 3200 Cherry Creek
Drive South, Suite 430, Denver, Colorado 80209.


     1.2. Acceptance of Subscription. The Company reserves the right to reject
the Subscriber's offer in whole or in part, for any reason, and to allocate less
than the maximum number of Shares the Subscriber hereby offers to purchase. Any
sale of Shares to the Subscriber shall not be deemed to occur until the
Subscriber's offer is accepted in writing by the Company. The Subscriber shall
not have any recourse against the Company if a purchase offer is rejected in
whole or in part. The Company shall reasonably notify the Subscriber in writing
of the acceptance of a purchase offer. If the offer is rejected in whole or in
part, the Company will promptly return to the Subscriber, without deduction or
interest, all or a ratable portion of the subscription price, as the case may
be, together with all executed documents tendered by the Subscriber. If the
purchase offer is rejected in part only, the Subscriber shall immediately
complete, execute and deliver to the Company new subscription documents for the
appropriate reduced amount. 50,000 Shares are being offered by the Company on a
"best efforts, all or none basis." Thus, unless all 50,000 Shares are sold, none
will be sold. Initially, any funds received from Subscribers will be held in a
non-interest bearing escrow account with an insured depository institution. If
the Company is not successful in its efforts to sell 50,000 Shares in the
initial 90-day offering, all funds received from Subscribers will be promptly
returned to the Subscribers. If the Company is successful, after receipt and
acceptance of subscriptions for 50,000 Shares, funds held in the escrow account
shall bear interest.

     1.3. Escrow of Funds and Certificate and Restriction on Transfer of Shares.
The Shares have been registered under the Securities Act of 1933, as amended
(the "Act"), and the offering thereof is being conducted pursuant to Rule 419
under the Act ("Rule 419"). In accordance with that rule, the Subscriber's
funds, representing the Purchase Price, delivered pursuant to this agreement,
shall be promptly deposited into an escrow account.


     Rule 419 requires that before the Shares can be released, the Company must
first execute an agreement to acquire a business. The agreement must provide for
the acquisition of a business or assets for which the fair value of the business
or net assets to be acquired represents at least 80% of the maximum offering
proceeds and which must also represent 50% of the gross proceeds of the offering
pursuant to requirements of the Colorado Securities Act.

     Once the acquisition agreement has been executed, Rule 419 requires the
Company to update the registration statement with a post-effective amendment.
The post-effective amendment must contain information about:

     (i)    the proposed acquisition candidate and its business, including the
            requisite financial statements;

     (ii)   the results of the offering;

     (iii)  the use of the funds disbursed from the escrow account; and

     (iv)   the terms of the reconfirmation offer.

     1.4. The Reconfirmation Offering. The reconfirmation offer must commence
within five business days after the effective date of the post-effective
amendment and must include the following conditions:

     (i)    the prospectus contained in the post-effective amendment will be
            sent to each Subscriber within five business days after the
            effective date of the post-effective amendment;

     (ii)   each Subscriber will have no fewer than 20, and no more than 45,
            business days from the effective date of the post-effective
            amendment to notify the Company in writing that he elects to remain
            a Subscriber;

     (iii)  if the Company does not receive written notification from any
            Subscriber within 45 business days following the effective date, the
            Subscriber's escrowed securities will be returned to the Company and
            the Subscriber's escrowed funds to the Subscriber;

     (iv)   unless Subscribers representing 80% of the maximum offering proceeds
            elect to remain Subscribers, the acquisition of the target business
            would be prevented, deposited securities held in escrow will be
            returned to the Company and the escrowed funds, plus interest, to
            the Subscribers; and

                                      -2-

<PAGE>


     (v)    if a consummated acquisition has not occurred within 18 months from
            the date of this prospectus, the deposited securities held in the
            escrow account will be returned to the Company and the escrowed
            funds, plus interest, to the Subscribers.

     The Shares may be released to Subscribers after the escrow agent has
received a signed representation from the Company and any other evidence
acceptable by the escrow agent that:

     (i)    the Company has executed an agreement for the acquisition of a
            business for which the fair market value of the business represents
            at least 80% of the maximum offering proceeds and the Company has
            filed the required post-effective amendment;

     (ii)   the completion of a transaction or series of transactions whereby at
            least 50% of the gross offering proceeds have been committed to a
            specific line of business as defined in the Colorado Securities Act
            and regulations;

     (iii)  the expiration of nine (9) days after the receipt by the Colorado
            Commissioner of Securities of a notice of the proposed release of
            funds or authorization of the Commissioner of any earlier release;

     (iv)   the post-effective amendment has been declared effective;

     (v)    the reconfirmation offer has been completed;

     (vi)   the Company has satisfied all of the prescribed conditions of the
            reconfirmation offer; and

     (vii)  the acquisition of the business or net assets with the fair value of
            at least 80% of the maximum proceeds has been consummated.

                                  ARTICLE II.
