Section 4.2      Transfer Restrictions.
 
(a)  The Securities may only be disposed of pursuant to an effective
registration statement under the Securities Act or pursuant to an available
exemption from the registration requirements of the Securities Act, and in
compliance with any applicable state securities laws. The Securities shall
contain a restrictive legend in the following form:
 
THESE SECURITIES HAVE NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE
COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN
EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
“SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT
TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO
AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE
REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.
 
(b)  Each Purchaser agrees that the removal of the restrictive legend from
certificates representing Securities as set forth in this Section 4.2 is
expressly predicated upon the Purchaser’s covenant and agreement in this Section
4.2(b) that the Purchaser shall in all cases sell or otherwise transfer the
Securities pursuant to:  (i) an effective registration statement under the
Securities Act, in full compliance with all prospectus delivery requirements
under the Securities Act and in accordance with the plan of distribution
described in the prospectus delivered by Purchaser, or (ii) an available
exemption from registration under the Securities Act.
 
Section 4.3     Furnishing of Information.
 
(a)   For such period as the Purchaser continues to own the Shares, the Company
covenants to use its reasonable efforts to timely file (or obtain extensions in
respect thereof and file within the applicable grace period) all reports
required to be filed by the Company after the date hereof pursuant to the
Exchange Act.  In addition, the Company shall use its reasonable efforts to take
all actions necessary to meet the “registrant eligibility” requirements set
forth in the general instructions to Form S-3 or any successor form thereto, to
continue to be eligible to register the resale of its Common Stock on a
registration statement on Form S-3 under the Securities Act.
 
(b)   For such period as the Purchaser continues to own the Shares, if the
Company is not required to file reports pursuant to the Exchange Act, it will
prepare and furnish to the Purchaser and make publicly available in accordance
with Rule 144 such information as is required for the Purchaser to sell the
Securities under Rule 144 and the Company further covenants that it will take
such further action as any holder of Securities may reasonably request, all to
the extent required from time to time to enable such Person to sell such
Securities without registration under the Securities Act within the limitation
of the exemptions provided by Rule 144.
 
 
12

--------------------------------------------------------------------------------

 
 
(c)  For such period as the Purchaser continues to own the Shares, the Company
shall ensure that each of the following reports are available at www.sec.gov: 
(i) within ten days after the filing thereof with the SEC, a copy of its Annual
Report on Form 10-K, its Quarterly Reports on Form 10-Q, its proxy statements
and any Current Reports on Form 8-K; and (ii) within one day after release,
copies of all press releases issued by the Company or any of its Subsidiaries.
 
Section 4.4 Trading Market of Common Stock.  The Company hereby agrees to use
its reasonable efforts to maintain the eligibility for trading of the Common
Stock on the Trading Market.  The Company further agrees, if the Company applies
to have the Common Stock traded on any other trading market, it will include in
such application the Shares, and will take such other action as is necessary or
desirable in the opinion of the Purchaser to cause the Shares to be listed on
such other trading market as promptly as possible.  The Company will take all
action reasonably necessary to continue the listing and trading of its Common
Stock on a trading market and will comply in all respects with the Company’s
reporting, filing and other obligations under the bylaws or rules of the trading
market.
 
Section 4.5  Sales by Purchasers. Each Purchaser covenants to sell any
Securities sold by it in compliance with applicable prospectus delivery
requirements, if any, or otherwise in compliance with the requirements for an
exemption from registration under the Securities Act.  Each Purchaser will not
make any sale, transfer or other disposition of the Securities in violation of
federal or state securities laws.
 
ARTICLE V
MISCELLANEOUS
 
Section 5.1.  Entire Agreement.  The Transaction Documents, together with the
exhibits and schedules thereto, contain the entire understanding of the parties
with respect to the Securities and supersede all prior agreements and
understandings, oral or written, with respect to such matters, which the parties
acknowledge have been merged into such documents, exhibits and schedules.
 
Section 5.2.  Amendments; Waivers.  No provision of this Agreement may be waived
or amended except in a written instrument signed, in the case of an amendment,
by the Company and the Purchaser or, in the case of a waiver, by the party
against whom enforcement of any such waiver is sought.  No waiver of any default
with respect to any provision, condition or requirement of this Agreement shall
be deemed to be a continuing waiver in the future or a waiver of any subsequent
default or a waiver of any other provision, condition or requirement hereof, nor
shall any delay or omission of either party to exercise any right hereunder in
any manner impair the exercise of any such right.
 
 
13

--------------------------------------------------------------------------------

 

Section 5.3.  Successors and Assigns.  This Agreement shall be binding upon and
inure to the benefit of the parties and their successors and permitted
assigns.  The Company may not assign this Agreement or any rights or obligations
hereunder without the prior written consent of the Purchaser; provided, however,
that no consent shall be required in connection with a merger, consolidation or
sale of substantially all of the Company’s assets.  Any Purchaser may assign any
or all of its rights under this Agreement to any Person in connection with the
transfer of the Securities, provided such transferee agrees in writing to be
bound, with respect to the transferred Securities, by the provisions hereof that
apply to the “Purchaser”.
 
Section 5.4.  No Third-Party Beneficiaries.  This Agreement is intended for the
benefit of the parties hereto and their respective successors and permitted
assigns and is not for the benefit of, nor may any provision hereof be enforced
by, any other Person.
 
Section 5.5.  Governing Law.  All questions concerning the construction,
validity, enforcement and interpretation of the Transaction Documents shall be
governed by and construed and enforced in accordance with the internal laws of
the State of Florida, without regard to the principles of conflicts of law
thereof.  Each party agrees that all legal proceedings concerning the
interpretations, enforcement and defense of the transactions contemplated by
this Agreement and any other Transaction Documents (whether brought against a
party hereto or its respective affiliates, directors, officers, shareholders,
employees or agents) shall be commenced exclusively in the United States federal
courts and the state courts located in the County of Hillsborough, State of
Florida.  Each party hereto hereby irrevocably submits to the exclusive
jurisdiction of the state and federal courts sitting in the County of
Hillsborough, State of Florida for the adjudication of any dispute hereunder or
in connection herewith or with any transaction contemplated hereby or discussed
herein (including with respect to the enforcement of any of the Transaction
Documents), and hereby irrevocably waives, and agrees not to assert in any suit,
action or proceeding, any claim that it is not personally subject to the
jurisdiction of any such court, that such suit, action or proceeding is
improper.  Each party hereto hereby irrevocably waives personal service of
process and consents to process being served in any such suit, action or
proceeding by delivering a copy thereof via overnight delivery (with evidence of
delivery) to such party at the address in effect for notices to it under this
Agreement and agrees that such service shall constitute good and sufficient
service of process and notice thereof.  Nothing contained herein shall be deemed
to limit in any way any right to serve process in any manner permitted by
law.  Each party hereto (including its affiliates, agents, officers, directors
and employees) hereby irrevocably waives, to the fullest extent permitted by
applicable law, any and all right to trial by jury in any legal proceeding
arising out of or relating to this Agreement or the transactions contemplated
hereby.  If either party shall commence an action or proceeding to enforce any
provisions of a Transaction Document, then the prevailing party in such action
or proceeding shall be reimbursed by the other party for its attorneys’ fees and
other costs and expenses incurred with the investigation, preparation and
prosecution of such action or proceeding.
 
Section 5.6.  Execution.  This Agreement may be executed in two or more
counterparts, all of which when taken together shall be considered one and the
same agreement and shall become effective when counterparts have been signed by
each party and delivered to the other party, it being understood that both
parties need not sign the same counterpart.  In the event that any signature is
delivered by facsimile or other electronic transmission, such signature shall
create a valid and binding obligation of the party executing (or on whose behalf
such signature is executed) with the same force and affect as if such facsimile
or other electronically transmitted signature page were an original thereof.
 
 
14

--------------------------------------------------------------------------------

 
 
Section 5.7.  Severability.  If any provision of this Agreement is held to be
invalid or unenforceable in any respect, the validity and enforceability of the
remaining terms and provisions of this Agreement shall not in any way be
affected or impaired thereby and the parties will attempt to agree upon a valid
and enforceable provision that is a reasonable substitute therefor, and upon so
agreeing, shall incorporate such substitute provision in this Agreement.
 
Section 5.8.  Construction.  The headings herein are for convenience only, do
not constitute a part of this Agreement and shall not be deemed to limit or
affect any of the provisions hereof.  The parties agree that each of them and/or
their respective counsel has reviewed and had an opportunity to revise the
Transaction Documents and, therefore, the normal rule of construction to the
effect that any ambiguities are to be resolved against the drafting party shall
not be employed in the interpretation of the Transaction Documents or any
amendments hereto.
 
Section 5.9.  Legal Counsel. The Company and KFLP acknowledge that the law firm
Shumaker, Loop & Kendrick, LLP ("Shumaker") currently represents the Company and
KFLP on unrelated matters.  The Company and KFLP hereby waive any potential
conflict of interest arising from the representation by Shumaker and consents to
the continued representation by Shumaker of the Company in connection with the
matters covered by this Agreement.  The KFLP further acknowledges and represents
that it has had an opportunity to retain its own separate legal counsel to
represent it in this matter.
