provided to the Purchaser and the representations and warranties of the Seller

Section 6 shall survive the purchase and sale of the Note and Warrant, and any
investigation made by the Seller shall not diminish the right of the Seller to

warrants to the Seller as follows.

6.1 ORGANIZATION. The Purchaser represents and warrants that it
is a limited liability company duly organized and validly existing under the
laws of the state of its formation and the

14
17
execution, delivery and performance by the Purchaser of this Agreement, each of
the Related Documents to which it is a party and of any instrument or agreement
required by this Agreement and the Related Documents to which it is a party are
within its powers, have been duly authorized, and are not in conflict with the
terms of any provision of its partnership agreement or other organizational
documents.

Agreement, the Related Documents and any other instrument or agreement required
by this Agreement to which the Purchaser is a party have been duly authorized
by all requisite action on the part of the Purchaser and are not in conflict

Purchaser is a party or by which the Purchaser is bound or affected.

6.3 ENFORCEABILITY. This Agreement is a legal, valid and binding
agreement of the Purchaser, enforceable against the Purchaser in accordance
with its terms and the Related Documents and any other instrument or agreement
required under this Agreement, when executed or delivered by the Purchaser,
will be legal, valid, binding and enforceable in accordance with their
respective terms, subject to (a) laws of general application relating to
bankruptcy, insolvency, and the relief of debtors, (b) rules of law governing
specific performance, injunctive relief, or other equitable remedies, and (c)

the meaning of Rule 501(a) of Regulation D promulgated under the Securities Act
and has substantial experience in evaluating and investing in securities of
companies similar to the Seller and has made investments of securities other

business or financial experience and financial condition, it has the ability to
analyze and bear the entire risk of its investment pursuant to this Agreement,
the Note and the Warrant.

The Purchaser may sell a beneficial interest (but not of record) in the Note
and a proportionate share of the Warrant Shares to Accredited Investors. The
Purchaser understands that the issuance and sale of the Securities purchased by
it hereunder (and

15
18
the issuance of Warrant Shares upon the exercise of the Warrant) have not been,
and will not be, subject to a registration statement filed under the Securities
Act or any applicable state securities law by reason of a specific exemption
from the registration provisions of the Securities Act and such state
securities laws, which exemption depends upon, among other things, the bona
fide nature of the investment intent and the accuracy of the Purchaser's
representation as expressed herein.

6.7 RULE 144. The Purchaser acknowledges that the securities
which are or could be acquired hereunder are restricted securities within the
meaning of Rule 144 promulgated under the Securities Act and must be held
indefinitely unless subsequently registered under the Securities Act and
applicable state securities laws or unless an exemption from such registration

hereunder. The purchase of such Securities is not a result of an advertisement
of an offering in connection with the sale of such Securities.

respect to the delivery of any one Financial Report shall be $2,500. The

of the Warrant, the Seller shall, unless the Purchaser waives compliance

12.1 INDEMNIFICATION. The Seller shall indemnify and hold the
Purchaser harmless from and against any and all Indemnified Losses related to,
caused by or arising from any misrepresentation, breach of warranty or failure
to fulfill any covenant or agreement contained herein, except to the extent
that any such loss, damage, expense, suit, action, claim, liability or
obligation arises from the Purchaser's gross negligence or willful misconduct,
and provided that in no event shall this Section 12 be construed to require the
Seller to indemnify the Purchaser with respect to any litigation or dispute
between the parties to the extent that the same is ultimately resolved in favor
of the Seller.

24
27
12.2 PROCEDURES FOR INDEMNIFIED LOSSES. In order to claim
Indemnified Losses under this Section:

(a) Purchaser shall give written Notice to the Seller of any
claimed Indemnified Losses, which Notice shall set forth a reasonably detailed
statement of the Indemnified Losses, including the cost, expense, loss, damage
and liability Purchaser has incurred and expects to incur by reason thereof.

(b) Such Indemnified Loss shall be effected on the last to occur
of (i) the expiration of 30 days from the date of such Notice (the "Notice of
Contest Period"); (ii) if such claim is contested as hereinafter provided, the
date the dispute is resolved in accordance with this Section, or (iii) the date
such claim becomes liquidated in amount.

(c) If, prior to the expiration of the Notice of Contest Period,
the Seller notifies Purchaser in writing of the Seller's intention to dispute
the claim for Indemnified Losses, and if such dispute is not resolved with 30
days after the expiration of such Notice of Contest Period ("Resolution
Period"), then the matter may be submitted by Purchaser and the Seller to a
Person recognized in the field of alternate dispute resolution agreed upon by
the Parties ("Mediator") within 10 days after the expiration of the Resolution
Period. The Mediator shall be requested to recommend to the Parties in writing
a procedure for non-binding mediation ("Mediation") to resolve such dispute.
The Parties shall cooperate and diligently pursue resolution through Mediation
within 45 days after the Mediator has been agreed upon. If the dispute cannot
be resolved within such period as the Mediator deems reasonable, the Mediator
shall, upon the request of Purchaser or the Seller, certify to the Parties that
the dispute is incapable of resolution through the Mediation process. The
expenses of such Mediation (excluding expenses incurred solely by Purchaser or
the Seller in such Mediation, which shall be borne by the party incurring such
expenses) shall be borne 50% by Purchaser and 50% by the Seller. Since the
Mediation is conducted for the purpose of settling the dispute, all proposals
and settlement offers shall be inadmissible for any purpose (including
arbitration) by virtue of Rule 408 of the Federal Rules of Evidence and the
principles expressed in such rule.

(d) If Purchaser and the Seller are unable to agree upon a
Mediator within 10 days after the Resolution Period or the Mediator certifies
to the Parties that the dispute is incapable of resolution through the
Mediation process, then such dispute shall be resolved by a committee of three
arbitrators (one appointed by the Seller, one appointed by Purchaser and one
appointed by the other two so appointed), who shall be appointed within 60 days
after such inability to agree or such certification by the Mediator. The
arbitrators shall be located in, and the arbitration shall take place, in
Columbus, Ohio in accordance with the rules of the American Arbitration
Association and their decision shall be final and binding on the Seller and
Purchaser. The expenses of such arbitration (excluding expenses incurred
solely by Purchaser or the Seller in bringing or defending such proceeding,
which shall be borne by the party incurring such expenses) shall be borne
one-half by Purchaser and one-half by the Seller. The Parties shall

25
28
cooperate and diligently pursue the arbitration of such claim for offset in
order for a decision to be made by the arbitrators within 45 days after their
appointment.
