                  a. MANDATORY REGISTRATION. The Company shall by no later than
10 Trading Days from the date hereof, file with the SEC the Registration
Statement. The Investor and its counsel shall have a reasonable opportunity to
review and comment upon such registration statement or amendment to such
registration statement and any related prospectus prior to its filing with the
SEC. Investor shall furnish all information reasonably requested by the Company
for inclusion therein. The Company shall use its best efforts to have the
Registration Statement or amendment declared effective by the SEC at the
earliest possible date. The Company shall use reasonable best efforts to keep
the Registration Statement effective pursuant to Rule 415 promulgated under the
1933 Act and available for sales of all of the Registrable Securities at all
times until the earlier of (i) the date as of which the Investor may sell all of
the Registrable Securities without restriction pursuant to Rule 144(k)
promulgated under the 1933 Act (or successor thereto) or (ii) the date on which
(A) the Investor shall have sold all the Registrable Securities and no Available
Amount remains under the Purchase Agreement (the "REGISTRATION Period"). The
Registration Statement (including any amendments or supplements thereto and
prospectuses contained therein) shall not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein, or
necessary to make the statements therein, in light of the circumstances in which
they were made, not misleading.

applicable securities regulations, from time to time file with the SEC, pursuant
to Rule 424 promulgated under the 1933 Act, the prospectus and prospectus
supplements, if any, to be used in connection with sales of the Registrable
Securities under the Registration Statement. The Investor and its counsel shall
have a reasonable opportunity to review and comment upon such prospectus prior
to its filing with the SEC. The Investor shall use its reasonable best efforts
to comment upon such prospectus within one (1) Trading Day from the date the
Investor receives the final version of such prospectus.

                  c. SUFFICIENT NUMBER OF SHARES REGISTERED. In the event the
number of shares available under the Registration Statement is insufficient to
cover all of the Registrable Securities, the Company shall amend the
Registration Statement or file a new registration statement (a "NEW REGISTRATION
STATEMENT"), so as to cover all of such Registrable Securities as soon as
practicable, but in any event not later than ten (10) Trading Days after the
necessity therefor arises. The Company shall use it reasonable best efforts to
cause such amendment and/or New Registration Statement to become effective as
soon as practicable following the filing thereof.

         3.       RELATED OBLIGATIONS.
                  --------------------

         With respect to the Registration Statement and whenever any Registrable
Securities are to be registered pursuant to Section 2(b) including on any New
Registration Statement, the Company shall use its reasonable best efforts to
effect the registration of the Registrable Securities in accordance with the
intended method of disposition thereof and, pursuant thereto, the Company shall
have the following obligations:

                  a. The Company shall prepare and file with the SEC such
amendments (including post-effective amendments) and supplements to any
registration statement and the prospectus used in connection with such
registration statement, which prospectus is to be filed pursuant to Rule 424
promulgated under the 1933 Act, as may be necessary to keep the Registration
Statement or any New Registration Statement effective at all times during the
Registration Period, and, during such period, comply with the provisions of the
1933 Act with respect to the disposition of all Registrable Securities of the
Company covered by the Registration Statement or any New Registration Statement
until such time as all of such Registrable Securities shall have been disposed
of in accordance with the intended methods of disposition by the seller or
sellers thereof as set forth in such registration statement.

                  b. The Company shall permit the Investor to review and comment
upon the Registration Statement or any New Registration Statement and all
amendments and supplements thereto at least two (2) Trading Days prior to their
filing with the SEC, and not file any document in a form to which Investor
reasonably objects. The Investor shall use its reasonable best efforts to
comment upon the Registration Statement or any New Registration Statement and
any amendments or supplements thereto within two (2) Trading Days from the date
the Investor receives the final version thereof. The Company shall furnish to
the Investor, without charge any correspondence from the SEC or the staff of the
SEC to the Company or its representatives relating to the Registration Statement
or any New Registration Statement.

                  c. Upon request of the Investor, the Company shall furnish to
the Investor, (i) promptly after the same is prepared and filed with the SEC, at
least one copy of such registration statement and any amendment(s) thereto,
including financial statements and schedules, all documents incorporated therein
by reference and all exhibits, (ii) upon the effectiveness of any registration
statement, ten (10) copies of the prospectus included in such registration
statement and all amendments and supplements thereto (or such other number of
copies as the Investor may reasonably request) and (iii) such other documents,
including copies of any preliminary or final prospectus, as the Investor may
reasonably request from time to time in order to facilitate the disposition of
the Registrable Securities owned by the Investor.

                  d. The Company shall use reasonable best efforts to (i)
register and qualify the Registrable Securities covered by a registration
statement under such other securities or "blue sky" laws of such jurisdictions
in the United States as the Investor reasonably requests, (ii) prepare and file
in those jurisdictions, such amendments (including post-effective amendments)
and supplements to such registrations and qualifications as may be necessary to
maintain the effectiveness thereof during the Registration Period, (iii) take
such other actions as may be necessary to maintain such registrations and
qualifications in effect at all times during the Registration Period, and (iv)
take all other actions reasonably necessary or advisable to qualify the
Registrable Securities for sale in such jurisdictions; provided, however, that

                                       3
<PAGE>

the Company shall not be required in connection therewith or as a condition
thereto to (x) qualify to do business in any jurisdiction where it would not
otherwise be required to qualify but for this Section 3(d), (y) subject itself
to general taxation in any such jurisdiction, or (z) file a general consent to
service of process in any such jurisdiction. The Company shall promptly notify
the Investor who holds Registrable Securities of the receipt by the Company of
any notification with respect to the suspension of the registration or
qualification of any of the Registrable Securities for sale under the securities
or "blue sky" laws of any jurisdiction in the United States or its receipt of
actual notice of the initiation or threatening of any proceeding for such
purpose.

                  e. As promptly as practicable after becoming aware of such
event or facts, the Company shall notify the Investor in writing of the
happening of any event or existence of such facts as a result of which the
prospectus included in any registration statement, as then in effect, includes
an untrue statement of a material fact or omits to state a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading, and
promptly prepare a supplement or amendment to such registration statement to
correct such untrue statement or omission, and deliver ten (10) copies of such
supplement or amendment to the Investor (or such other number of copies as the
Investor may reasonably request). The Company shall also promptly notify the
Investor in writing (i) when a prospectus or any prospectus supplement or
post-effective amendment has been filed, and when a registration statement or
any post-effective amendment has become effective (notification of such
effectiveness shall be delivered to the Investor by facsimile on the same day of
such effectiveness and by overnight mail), (ii) of any request by the SEC for
amendments or supplements to any registration statement or related prospectus or
related information, and (iii) of the Company's reasonable determination that a
post-effective amendment to a registration statement would be appropriate.

                  f. The Company shall use its reasonable best efforts to
prevent the issuance of any stop order or other suspension of effectiveness of
any registration statement, or the suspension of the qualification of any
Registrable Securities for sale in any jurisdiction and, if such an order or
suspension is issued, to obtain the withdrawal of such order or suspension at
the earliest possible moment and to notify the Investor of the issuance of such
order and the resolution thereof or its receipt of actual notice of the
initiation or threat of any proceeding for such purpose.

                  g. The Company shall (i) cause all the Registrable Securities
to be listed on each securities exchange on which securities of the same class
or series issued by the Company are then listed, if any, if the listing of such
Registrable Securities is then permitted under the rules of such exchange, or
(ii) secure designation and quotation of all the Registrable Securities on the
Principal Market. The Company shall pay all fees and expenses in connection with
satisfying its obligation under this Section.

                  h. The Company shall cooperate with the Investor to facilitate
the timely preparation and delivery of certificates (not bearing any restrictive
legend) representing the Registrable Securities to be offered pursuant to any
registration statement and enable such certificates to be in such denominations
or amounts as the Investor may reasonably request and registered in such names
as the Investor may request.

                  i. The Company shall at all times provide a transfer agent and
registrar with respect to its Common Stock.

                  j. If reasonably requested by the Investor, the Company shall
(i) immediately incorporate in a prospectus supplement or post-effective
amendment such information as the Investor believes should be included therein
relating to the sale and distribution of Registrable Securities, including,
without limitation, information with respect to the number of Registrable
Securities being sold, the purchase price being paid therefor and any other
terms of the offering of the Registrable Securities; (ii) make all required
filings of such prospectus supplement or post-effective amendment as soon as
notified of the matters to be incorporated in such prospectus supplement or
post-effective amendment; and (iii) supplement or make amendments to any
registration statement.

                                       4
<PAGE>

                  k. The Company shall use its reasonable best efforts to cause
the Registrable Securities covered by the any registration statement to be
registered with or approved by such other governmental agencies or authorities
as may be necessary to consummate the disposition of such Registrable
Securities.

                  l. Within one (1) Trading Day after any registration statement
which includes the Registrable Securities is ordered effective by the SEC, the
Company shall deliver, and shall cause legal counsel for the Company to deliver,
to the transfer agent for such Registrable Securities (with copies to the
Investor) confirmation that such registration statement has been declared
effective by the SEC in the form attached hereto as EXHIBIT A.

                  m. The Company shall take all other reasonable actions
necessary to expedite and facilitate disposition by the Investor of Registrable
Securities pursuant to any registration statement.

         4.       OBLIGATIONS OF THE INVESTOR.
                  ----------------------------

                  a. The Company shall notify the Investor in writing of the
information the Company reasonably requires from the Investor in connection with
any registration statement hereunder. The Investor shall furnish to the Company
such information regarding itself, the Registrable Securities held by it and the
intended method of disposition of the Registrable Securities held by it as shall
be reasonably required to effect the registration of such Registrable Securities
and shall execute such documents in connection with such registration as the
Company may reasonably request.

                  b. The Investor agrees to cooperate with the Company as
reasonably requested by the Company in connection with the preparation and
filing of any registration statement hereunder.

                  c. The Investor agrees that, upon receipt of any notice from
the Company of the happening of any event or existence of facts of the kind
described in Section 3(f) or the first sentence of 3(e), the Investor will
immediately discontinue disposition of Registrable Securities pursuant to any
registration statement(s) covering such Registrable Securities until the
Investor's receipt of the copies of the supplemented or amended prospectus
contemplated by Section 3(f) or the first sentence of 3(e). Notwithstanding
anything to the contrary, the Company shall cause its transfer agent to promptly
deliver shares of Common Stock without any restrictive legend in accordance with
the terms of the Purchase Agreement in connection with any sale of Registrable
Securities with respect to which an Investor has entered into a contract for
sale prior to the Investor's receipt of a notice from the Company of the
happening of any event of the kind described in Section 3(f) or the first
sentence of 3(e) and for which the Investor has not yet settled.

         5.       EXPENSES OF REGISTRATION.
                  -------------------------

                  All reasonable expenses, other than sales or brokerage
commissions, incurred in connection with registrations, filings or
qualifications pursuant to Sections 2 and 3, including, without limitation, all
registration, listing and qualifications fees, printers and accounting fees, and
fees and disbursements of counsel for the Company, shall be paid by the Company.

                                       5
<PAGE>

         6.       INDEMNIFICATION.
                  ----------------

                  a. To the fullest extent permitted by law, the Company will,
and hereby does, indemnify, hold harmless and defend the Investor, each Person,
if any, who controls the Investor, the members, the directors, officers,
partners, employees, agents, representatives of the Investor and each Person, if
any, who controls the Investor within the meaning of the 1933 Act or the
Securities Exchange Act of 1934, as amended (the "1934 ACT") (each, an
"INDEMNIFIED PERSON"), against any losses, claims, damages, liabilities,
judgments, fines, penalties, charges, costs, attorneys' fees, amounts paid in
settlement or expenses, joint or several, (collectively, "CLAIMS") incurred in
investigating, preparing or defending any action, claim, suit, inquiry,
proceeding, investigation or appeal taken from the foregoing by or before any
court or governmental, administrative or other regulatory agency, body or the
SEC, whether pending or threatened, whether or not an indemnified party is or
may be a party thereto ("INDEMNIFIED DAMAGES"), to which any of them may become
subject insofar as such Claims (or actions or proceedings, whether commenced or
threatened, in respect thereof) arise out of or are based upon: (i) any untrue
statement or alleged untrue statement of a material fact in the Registration
Statement, any New Registration Statement or any post-effective amendment
thereto or in any filing made in connection with the qualification of the
offering under the securities or other "blue sky" laws of any jurisdiction in
which Registrable Securities are offered ("BLUE SKY FILING"), or the omission or
alleged omission to state a material fact required to be stated therein or
necessary to make the statements therein not misleading, (ii) any untrue
statement or alleged untrue statement of a material fact contained in the final
prospectus (as amended or supplemented, if the Company files any amendment
thereof or supplement thereto with the SEC) or the omission or alleged omission
to state therein any material fact necessary to make the statements made
therein, in light of the circumstances under which the statements therein were
made, not misleading, (iii) any violation or alleged violation by the Company of
the 1933 Act, the 1934 Act, any other law, including, without limitation, any
state securities law, or any rule or regulation thereunder relating to the offer
or sale of the Registrable Securities pursuant to the Registration Statement or
any New Registration Statement or (iv) any material violation by the Company of
this Agreement (the matters in the foregoing clauses (i) through (iv) being,
collectively, "VIOLATIONS"). The Company shall reimburse each Indemnified Person
promptly as such expenses are incurred and are due and payable, for any legal
fees or other reasonable expenses incurred by them in connection with
investigating or defending any such Claim. Notwithstanding anything to the
contrary contained herein, the indemnification agreement contained in this
Section 6(a): (i) shall not apply to a Claim by an Indemnified Person arising
out of or based upon a Violation which occurs in reliance upon and in conformity
with information furnished in writing to the Company by such Indemnified Person
expressly for use in connection with the preparation of the Registration
Statement, any New Registration Statement or any such amendment thereof or
supplement thereto, if such prospectus was timely made available by the Company
pursuant to Section 3(c) or Section 3(e); (ii) with respect to any superceded
prospectus, shall not inure to the benefit of any such person from whom the
person asserting any such Claim purchased the Registrable Securities that are
the subject thereof (or to the benefit of any person controlling such person) if
the untrue statement or omission of material fact contained in the superceded
prospectus was corrected in the revised prospectus, as then amended or
supplemented, if such revised prospectus was timely made available by the
Company pursuant to Section 3(c) or Section 3(e), and the Indemnified Person was
promptly advised in writing not to use the incorrect prospectus prior to the use
giving rise to a violation and such Indemnified Person, notwithstanding such
advice, used it; (iii) shall not be available to the extent such Claim is based
on a failure of the Investor to deliver or to cause to be delivered the
prospectus made available by the Company, if such prospectus was timely made
available by the Company pursuant to Section 3(c) or Section 3(e); and (iv)
shall not apply to amounts paid in settlement of any Claim if such settlement is
effected without the prior written consent of the Company, which consent shall
not be unreasonably withheld. Such indemnity shall remain in full force and
effect regardless of any investigation made by or on behalf of the Indemnified
Person and shall survive the transfer of the Registrable Securities by the
Investor pursuant to Section 9.

                                       6
<PAGE>

                  b. In connection with the Registration Statement or any New
Registration Statement, the Investor agrees to severally and not jointly
indemnify, hold harmless and defend, to the same extent and in the same manner
as is set forth in Section 6(a), the Company, each of its directors, each of its
officers who signs the Registration Statement or any New Registration Statement,
each Person, if any, who controls the Company within the meaning of the 1933 Act
or the 1934 Act (collectively and together with an Indemnified Person, an
"INDEMNIFIED PARTY"), against any Claim or Indemnified Damages to which any of
them may become subject, under the 1933 Act, the 1934 Act or otherwise, insofar
as such Claim or Indemnified Damages arise out of or are based upon any
Violation, in each case to the extent, and only to the extent, that such
Violation occurs in reliance upon and in conformity with written information
about the Investor set forth on EXHIBIT B attached hereto and furnished to the
Company by the Investor expressly for use in connection with such registration
statement; and, subject to Section 6(d), the Investor will reimburse any legal
or other expenses reasonably incurred by them in connection with investigating
or defending any such Claim; provided, however, that the indemnity agreement
contained in this Section 6(b) and the agreement with respect to contribution
contained in Section 7 shall not apply to amounts paid in settlement of any
Claim if such settlement is effected without the prior written consent of the
Investor, which consent shall not be unreasonably withheld; provided, further,
however, that the Investor shall be liable under this Section 6(b) for only that
amount of a Claim or Indemnified Damages as does not exceed the net proceeds to
the Investor as a result of the sale of Registrable Securities pursuant to such
registration statement. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of such Indemnified Party
and shall survive the transfer of the Registrable Securities by the Investor
pursuant to Section 9.

                  c. Promptly after receipt by an Indemnified Person or
Indemnified Party under this Section 6 of notice of the commencement of any
action or proceeding (including any governmental action or proceeding) involving
a Claim, such Indemnified Person or Indemnified Party shall, if a Claim in
respect thereof is to be made against any indemnifying party under this Section
6, deliver to the indemnifying party a written notice of the commencement
thereof, and the indemnifying party shall have the right to participate in, and,
to the extent the indemnifying party so desires, jointly with any other
indemnifying party similarly noticed, to assume control of the defense thereof
with counsel mutually satisfactory to the indemnifying party and the Indemnified
Person or the Indemnified Party, as the case may be; provided, however, that an
Indemnified Person or Indemnified Party shall have the right to retain its own
counsel with the fees and expenses to be paid by the indemnifying party, if, in
the reasonable opinion of counsel retained by the indemnifying party, the
representation by such counsel of the Indemnified Person or Indemnified Party
and the indemnifying party would be inappropriate due to actual or potential
differing interests between such Indemnified Person or Indemnified Party and any
other party represented by such counsel in such proceeding. The Indemnified
Party or Indemnified Person shall cooperate fully with the indemnifying party in
connection with any negotiation or defense of any such action or claim by the
indemnifying party and shall furnish to the indemnifying party all information
reasonably available to the Indemnified Party or Indemnified Person which
relates to such action or claim. The indemnifying party shall keep the
Indemnified Party or Indemnified Person fully apprised at all times as to the
status of the defense or any settlement negotiations with respect thereto. No
indemnifying party shall be liable for any settlement of any action, claim or
proceeding effected without its written consent, provided, however, that the
indemnifying party shall not unreasonably withhold, delay or condition its
consent. No indemnifying party shall, without the consent of the Indemnified
Party or Indemnified Person, consent to entry of any judgment or enter into any
settlement or other compromise which does not include as an unconditional term
thereof the giving by the claimant or plaintiff to such Indemnified Party or
Indemnified Person of a release from all liability in respect to such claim or
litigation. Following indemnification as provided for hereunder, the
indemnifying party shall be subrogated to all rights of the Indemnified Party or
Indemnified Person with respect to all third parties, firms or corporations

                                       7
<PAGE>

relating to the matter for which indemnification has been made. The failure to
deliver written notice to the indemnifying party within a reasonable time of the
commencement of any such action shall not relieve such indemnifying party of any
liability to the Indemnified Person or Indemnified Party under this Section 6,
except to the extent that the indemnifying party is prejudiced in its ability to
defend such action.

                  d. The indemnification required by this Section 6 shall be
made by periodic payments of the amount thereof during the course of the
investigation or defense, as and when bills are received or Indemnified Damages
are incurred.

                  e. The indemnity agreements contained herein shall be in
addition to (i) any cause of action or similar right of the Indemnified Party or
Indemnified Person against the indemnifying party or others, and (ii) any
liabilities the indemnifying party may be subject to pursuant to the law.

         7.       CONTRIBUTION.
                  -------------

                  To the extent any indemnification by an indemnifying party is
prohibited or limited by law, the indemnifying party agrees to make the maximum
contribution with respect to any amounts for which it would otherwise be liable
under Section 6 to the fullest extent permitted by law; provided, however, that:
(i) no seller of Registrable Securities guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the 1933 Act) shall be entitled to
contribution from any seller of Registrable Securities who was not guilty of
fraudulent misrepresentation; and (ii) contribution by any seller of Registrable
Securities shall be limited in amount to the net amount of proceeds received by
such seller from the sale of such Registrable Securities.

         8.       REPORTS AND DISCLOSURE UNDER THE SECURITIES ACTS.
                  -------------------------------------------------

                  With a view to making available to the Investor the benefits
of Rule 144 promulgated under the 1933 Act or any other similar rule or
regulation of the SEC that may at any time permit the Investor to sell
securities of the Company to the public without registration ("RULE 144"), the
Company agrees, at the Company's sole expense, to:

                  a. make and keep public information available, as those terms
are understood and defined in Rule 144;

                  b. file with the SEC in a timely manner all reports and other
documents required of the Company under the 1933 Act and the 1934 Act so long as
the Company remains subject to such requirements and the filing of such reports
and other documents is required for the applicable provisions of Rule 144; and

                  c. furnish to the Investor so long as the Investor owns
Registrable Securities, promptly upon request, (i) a written statement by the
Company that it has complied with the reporting and or disclosure provisions of
Rule 144, the 1933 Act and the 1934 Act, (ii) a copy of the most recent annual
or quarterly report of the Company and such other reports and documents so filed
by the Company, and (iii) such other information as may be reasonably requested

                          DATED AS OF FEBRUARY 1, 2003
                  FROM H&L CONCEPTS, INC. TO ROBERT M. FELDMAN
                    AND GUARANTEED BY HEALTH & LEISURE, INC.

                            COGNOVIT PROMISSORY NOTE

$25,600                                                         February 1, 2003

         FOR VALUE RECEIVED, H & L Concepts, Inc., an Ohio corporation, whose
address is 203 East Broad Street, Columbus, Ohio 43215 ("Maker"), promises to
pay to the order of Robert M. Feldman, an individual, whose address is 2720
Sonata Drive, Columbus, Ohio 43209 ("Payee"), the principal sum of Twenty-Five
Thousand Six Hundred ($25,600) Interest will be earned on the principal amount
of this note at the rate of 6.5% per annum. The principal sum, plus accrued
interest thereon, is due and payable in 60 equal monthly installments of
principal and interest beginning March 1, 2004, with interest accrued through
February 28, 2004, being added to principal. The first payment shall be due and
payable March 1, 2004, and payments shall continue on the first day of each
month thereafter until all principal and accrued interest is paid in full. All
or any portion of the principal and accrued interest may be prepaid at any time
without penalty. All prepayments shall be applied first to accrued interest and
then to principal in inverse order of maturity. Notwithstanding the foregoing to
the contrary, in the event of a change in control of Health & Leisure, Inc., a
Delaware corporation, or in the event of a change in control of the Maker, at
the option of the holder of this note, all principal and accrued interest under
this Note shall become and be immediately due and payable. For purposes of this
Note, a change in control is defined to mean:

         (i) When any "person" as defined in Section 3(a)(9) of the Securities
Exchange Act of 1934 (the "Exchange Act") and as used in Sections 13(d) and
14(d) thereof, including a "group" as defined in Section 13(d) of the Exchange
Act, but excluding the Company and any subsidiary and any employee benefit plan
sponsored or maintained by the Company or any subsidiary (including any trustee
of such plan acting as trustee), directly or indirectly, becomes the "beneficial
owner" (as defined in Rule 13d-3 under the Exchange Act, as amended from time to
time) of securities of the Company representing 20% or more of the combined
voting power of the Company's then outstanding securities; or

         (ii) When, during any period of 24 consecutive months, the individuals
who, at the beginning of such period, constitute the Board of Directors (the
"Incumbent Directors") cease for any reason other than death to constitute at
least a majority thereof; provided, however, that a director who was not a
director at the beginning of such 24-month period shall be deemed to have
satisfied such 24-month requirement (and be an Incumbent Director) if such
director was elected by, or on the recommendation of or with the approval of, at
least two-thirds of the directors who then qualified as Incumbent Directors
either actually (because they were directors at the beginning of such 24-month
period) or by prior operation of this subparagraph (ii); or

         (iii) Upon the occurrence of a transaction requiring stockholder
approval for the acquisition of the Company by an entity other than the Company
or a subsidiary through purchase of assets, purchase of stock, by merger or
otherwise.

<PAGE>

         All payments under this Note shall be payable at Payee's address
indicated above or at such other address as any holder of this Note may from
time to time designate in writing to Maker.

         Upon default in payment of any installment within 10 days after the
same is due, this Note shall, at the option of the holder hereof, bear interest
thereafter at the rate of 12% per annum, and the entire principal hereof then
remaining unpaid, together with all accrued interest, shall at said holder's
option, become immediately due and payable without any notice or demand.

         All persons now or hereafter liable for the payment of the principal or
interest due on this Note, or any part thereof, do hereby expressly waive
presentment for payment, notice of dishonor, protest and notice of protest and
agree that the time for the payment of this Note may be extended without
releasing or otherwise affecting their liability on this Note.

         Each right, power or privilege specified or referred to in this Note or
in any related writing is in addition to any other rights, powers and privileges
that Payee may otherwise have or require by operation of law, by other contract
or otherwise. No course of dealing in respect of, nor any omission or delay in
the exercise of, any right, power, or privilege by Payee or the holder hereof
shall operate as a waiver thereof, nor shall any single or partial exercise
thereof preclude any further or other exercise thereof or of any other, as each
right, power or privilege may be exercised independently or concurrently with
others and as often and in such order as the holder may deem expedient. No
waiver or consent granted by the holder in respect of this Note or any related
writing shall be binding upon the holder unless specifically granted in writing,
which writing shall be strictly construed. Each right, power or privilege
granted to the holder in this Note or in any related writing is for the benefit
of and exercisable by each subsequent holder, if any, of this Note, and all
provisions of this Note shall be binding upon Maker, its successors and assigns,
including each subsequent holder, if any, of this Note.

         Maker hereof and the undersigned guarantor, each irrevocably authorizes
any attorney at law to appear for it in any court in Franklin County, Ohio, with
or without process, at any time after the above indebtedness becomes due, to
waive the issuance and service of process, to admit the maturity and nonpayment
of the indebtedness and to confess judgment against Maker and/or such guarantor
in favor of the holder of this Note for the amount then appearing due, together
with costs of suit, and thereupon to release all errors and waive all right of
second trial, appeal, and stay of execution. The foregoing warrant of attorney
shall survive any judgment. Should any judgment be vacated for any reason, the
foregoing warrant of attorney may thereafter be utilized for obtaining
additional judgment or judgments.
