      Re:   Lock-Up of Shares of Common Stock

Ladies and Gentlemen:

      The  undersigned  party  or  parties  (whether  one or more,  referred  to
collectively  herein as the  "undersigned")  is delivering this letter agreement
(this "letter  agreement")  to you in connection  with and as a condition to (i)
the  closing of the  private  placement  conducted  by CCP  Worldwide,  Inc.,  a
Delaware  corporation  (the  "Company"),  of  "Investment  Units" (the  "Private
Placement")  consisting  of shares of common  stock of the Company  (the "Common
Stock")  and  warrants  to  purchase  shares  of  the  Common  Stock  ("Investor
Warrants"),  and (ii) the  consummation of a reverse  triangular  merger between
Dyadic International, Inc., a Florida corporation ("Dyadic"), and a wholly-owned
subsidiary of the Company,  pursuant to which Dyadic will become a  wholly-owned
subsidiary  of the Company and Dyadic's  shareholders  will become the owners of
shares of Common  Stock (the  "Merger")  (the Private  Placement  and the Merger
being hereinafter collectively referred to as the "Transactions"). Following the
consummation  of  the   Transactions,   the  Company  will  be  renamed  "Dyadic
International, Inc."

      The undersigned is currently the holder of 295,000  outstanding  shares of
Common Stock of the Company.  In connection with the  Transactions,  the Company
has agreed to use its  reasonable  best  efforts  file a Form SB-2  Registration
Statement  (the  "Registration  Statement")  with the  Securities  and  Exchange
Commission ("SEC") in order to register the resale of the shares of Common Stock
sold in the Private Placement and certain of the shares of Common Stock received
by existing Dyadic stockholders,  including the undersigned,  as a result of the
Merger. The Company expects that the SEC will declare the Registration Statement
effective on a date (the "Effective  Date") that is no later than six (6) months
following the consummation of the Merger (the "Outside Date"). As a condition to
the consummation of the Merger,  the Company and Dyadic have required,  and as a
condition to participating in the Private Placement, the placement agents, Brean
Murray & Co.,  Inc.  ("BMCI")  and  Sanders  Morris  Harris Inc.  ("SMH"),  have
required,  that the undersigned  enter into a lock up agreement with the Company
by which he agrees not to  transfer  certain  of his shares of Common  Stock for
specified periods following consummation of the Transactions.

of the  consummation of the Transactions and six (6) months after the earlier of
the Effective Date or the Outside Date (the "6-Month  Lock-Up  Period"),  either
privately  sell,  contract to sell or  otherwise  transfer  (unless the proposed
transferee agrees to be bound by the restrictions on transfer  contained in this
letter agreement),  or publicly sell,  contract to sell, or otherwise  transfer,
all  or any  portion  of  112,500  of the  shares  of  Common  Stock  which  the
undersigned beneficially owns;

      (ii) agrees that,  without the prior written consent of the Company,  BMCI
and  SMH  (which  consent  may  be  withheld  in  their  sole  discretion),  the

contract to sell or otherwise transfer (unless the proposed transferee agrees to
be bound by the restrictions on transfer contained in this letter agreement), or
publicly sell,  contract to sell, or otherwise  transfer,  all or any portion of
56,250 of the shares of Common Stock which the  undersigned  beneficially  owns;

      (iii)  authorizes  the  Company  during  the  6-Month  Lock-Up  Period and
One-Year Lock-Up Period to cause the Company's  transfer agent to place a legend
on any  certificates  representing,  and to decline to transfer and to note stop
transfer  restrictions  on the  transfer  books and records of the Company  with
respect to, the shares of Common Stock that are restricted from transfer by this

representatives,  successors  and assigns of the  undersigned.  The  undersigned
further  understands  that the  consummation of the Transactions is subject to a

and Dyadic's  shareholders will become the owners of shares of Common Stock (the
"Merger") (the Private Placement and the Merger being  hereinafter  collectively
referred  to  as  the   "Transactions").   Following  the  consummation  of  the
Transactions, the Company will be renamed "Dyadic International, Inc."

      The  undersigned is currently the holder of  outstanding  shares of common
stock of Dyadic  ("Dyadic  Shares")  that will be exchanged for shares of Common
Stock as a result  of the  Merger.  In  connection  with the  Transactions,  the
Company  has  agreed  to use  its  reasonable  best  efforts  file  a Form  SB-2
Registration  Statement (the  "Registration  Statement") with the Securities and
Exchange  Commission  ("SEC") in order to  register  the resale of the shares of
Common Stock sold in the Private  Placement  and certain of the shares of Common
Stock received by existing Dyadic stockholders,  including the undersigned, as a
result  of the  Merger.  The  Company  expects  that  the SEC will  declare  the
Registration  Statement  effective on a date (the  "Effective  Date") that is no
later than six (6) months following the consummation of the Merger (the "Outside
Date"). As a condition to the consummation of the Merger, the Company and Dyadic
have required, and as a condition to participating in the Private Placement, the
placement  agents,  Brean Murray & Co., Inc.  ("BMCI") and Sanders Morris Harris
Inc.  ("SMH"),  have required,  that certain  existing holders of Dyadic Shares,
including the  undersigned,  enter into lock up  agreements  with the Company by
which they agree not to transfer the shares of Common Stock that they receive in
the Merger for a specified period following consummation of the Transactions.
