                              CAVIT SCIENCES, INC.
                         COMMON STOCK PURCHASE AGREEMENT

     This COMMON STOCK PURCHASE AGREEMENT ("Agreement") is made this 23rd day of
May 2006 by and between CAVIT SCIENCES,  INC., a Florida corporation ("CAVIT" or
the "Company"), and RAYMOND S. BAZLEY ("Bazley" or "Investor").

                                   Background

     As more fully set forth  herein,  Investor has agreed to purchase  from the
Company  shares of Common Stock of the Company  ("Common  Stock") for a purchase
price not to exceed $24,000.00 ("Commitment Amount").

Agreement

     NOW, THEREFORE,  intending to be legally bound hereby, the parties agree as
follows:

     1. Commitment.  Subject to the terms and conditions hereof, Investor agrees
to purchase  from CAVIT shares of Common  Stock at a purchase  price of $.08 per
share ("Commitment Purchase Amount") not to exceed the Commitment Amount.

     2. Share  Issuance.  Upon the payment of the  Commitment  Purchase Price as
aforesaid, the Company shall issue and cause to be delivered with all reasonable
dispatch to Investor and in the name of Investor,  a certificate or certificates
for the  number of shares of Common  Stock so  purchased.  Such  certificate  or
certificates shall be deemed to have been issued and Investor shall be deemed to
have become a holder of record of such Common Stock on and as of the date of the
delivery  to the  Company of and  payment of the  Commitment  Purchase  Price as
aforesaid.  If,  however,  at the date of  payment of such  Commitment  Purchase
Price, the transfer books for the Common Stock shall be closed, the certificates
for the Common Stock shall be issued and Investor shall become a record owner of
such  Common  Stock on and as of the  next  date on which  such  books  shall be
opened,  and until such date the  Company  shall be under no duty to deliver any
certificate for such Common Stock.

     3.  Representations  by Investor.  Investor  represents and warrants to the
Company as follows:

     a) Investor has relied only upon the information presented and contained in
     the Term Sheet provided by the Company ("Offering Materials"). Investor has
     had the opportunity to ask of the person or persons acting on behalf of the
     Company any and all relevant questions in connection with any aspect of the
     Company  including,  but not  limited to, the Common  Stock  offered by the
     Offering  Materials and has received answers which Investor considers to be
     reasonably  responsive to such questions.  Investor has had the opportunity
     to  verify  the  accuracy  of the  information  contained  in the  Offering
     Materials.

     (b) Investor  understands that Investor is subscribing for the Common Stock
     without being furnished any literature or prospectus in connection with the
     Offering  other than the Offering  Materials,  and that the Offering of the

                                       1

     Common  Stock  presented  in the  Offering  Materials  will not  have  been
     scrutinized by the Securities and Exchange  Commission or by the securities
     administrator  or similar  bureau,  agency,  or  department of the state of
     Investor's' residence.

     (c) Investor  understands (i) that the Common Stock has not been registered
     under the  Securities  Act of 1933,  as amended  ("Act"),  or registered or
     qualified under the securities laws of the state of Investor's'  residence,
     (ii) Investor has no right to require such  registration or  qualification,
     and (iii)  that,  therefore  Investor  must bear the  economic  risk of the
     investment  for an  indefinite  period of time because the Common Stock may
     not be sold unless so registered  or qualified or unless an exemption  from
     such registration and qualification is available.

     (d) The Common  Stock is being  purchased  for  Investor's  own account for
     investment  purposes  only and not for the interest of any other person and
     is not  being  purchased  with a view to or for the  resale,  distribution,
     subdivision or fractionalization  thereof.  Investor understands that there
     is not currently, and may not be at any future date, any established public
     trading market for the sale of such securities.

     (e) Investor is able to bear the economic  risks related to purchase of the
     Common Stock for an  indefinite  period of time (i.e.,  Investor is able to
     afford a complete  loss of the Common  Stock  Investor  is  subscribing  to
     purchase).  Investor's  net  worth  and  assets  are  sufficient  to enable
     Investor to purchase shares of Common Stock from Cavit in the amount of the
     Commitment Amount pursuant to this Agreement.

     (f)  Investor's  overall  commitment to  investments  which are not readily
     marketable is not  disproportionate  to Investor's net worth and Investor's
     investment in the Company will not cause such overall  commitment to become
     excessive.

     (g) Investor has adequate means of providing for  Investor's  current needs
     and possible personal contingencies.  Investor has no need for liquidity of
     the Common Stock  subscribed  to be  purchased  hereby and has no reason to
     anticipate any change in Investor's  personal  circumstances,  financial or
     otherwise,  which might cause or require any sale or  distribution  of such
     Common Stock subscribed to be purchased.

     (h) Investor  recognizes  that the purchase of the Common Stock  involves a
     high degree of risk including those special risks.

     (i) Investor understands that Investor's right to transfer the Common Stock
     will be restricted as set forth on the  certificate  evidencing  the Common
     Stock. Such restrictions  include  provisions  against transfer unless such
     transfer is not in violation  of the Act, or  applicable  state  securities
     laws (including investor suitability standards).

     (j) All information  which Investor has provided to the Company  including,
     but not  limited  to,  financial  position,  and  status  as an  accredited
     investor,  and knowledge of financial and business matters is true, correct
     and  complete  as of the  date of  execution  of this  Agreement.  Investor
     understands  that the  Company  will  rely in a  material  degree  upon the
     representations contained herein.

     (k)  Investor  understands  that a  legend  may  be  placed  on  any  stock
     certificate  representing  the Common Stock  substantially to the following
     effect:

     On the front side:

     "Transfer of the shares represented by this certificate is restricted - see
reverse side."

                                       2

     On the reverse side:

     "The  shares  represented  by this  certificate  have  been  issued  to the
registered owner in reliance upon written representations that these shares have
been taken for  investment.  These  shares  have not been  registered  under the
Securities Act of 1933, as amended ("Act"), and may not be sold,  transferred or
assigned  unless an opinion  of counsel  satisfactory  to the  company  has been
received  by the company to the effect  that such sale,  transfer or  assignment
will not be in  violation of the Act and the rules and  regulations  promulgated
thereunder or applicable state securities laws."

     (l) Investor is an "accredited investor" as defined in Rule 501 promulgated
under the Act because  Investor's  individual net worth (or Investor's joint net
worth with his spouse) on the date hereof exceeds $1,000,000.

     4.  Anti-Dilution;  Right of First  Refusal.  Subject  and  pursuant to the
provisions of this Section 4:

     a. The Company agrees to protect  Investor  against  dilution of Investor's
     ownership percentage of the Company's common stock in the event the Company
     issues for purposes other than raising capital,  in which event the Company
     shall issue to the Investor such additional shares of Common Stock as shall
     be necessary to maintain Investor's percentage ownership in the Company.

     b. In the event the  Company  decides to offer  additional  share of Common
     Stock for sale in the  future,  the  Investor  shall  have a right of first
     refusal to  purchase  Investor's  pro rate  portion  of such  shares on the
     identical terms and conditions as in such offer.

     5.  Securities  Laws.  As a condition  to the  issuance of any Common Stock
pursuant   this   Agreement,   Investor   shall   execute   and   deliver   such
representations,  warranties,  and covenants, that may be required by applicable
federal and state  securities law, or that the Company  determines is reasonably
necessary in connection with the issuance of such Common Stock. In addition, the
certificates  representing  the Common  Stock shall  contain  such  legends,  or
restrictive  legends,  or stop  transfer  instructions,  as shall be required by
applicable Federal or state securities laws, or as shall be reasonably  required
by the Company or its transfer agent. The Investor has completed and delivered a
Subscriber  Questionnaire,   which  is  attached  hereto  as  Exhibit  "A,"  and
incorporated herein by reference.

     6.  Binding  Effect.  This  Agreement  shall be  binding  upon the  party's
respective heirs, personal  representatives,  successors and assigns;  provided,
however, that this Agreement shall not be assignable by Investor, in whole or in
part, without the prior consent of the Company.

     7.  Applicable  Law. This  Agreement  shall be deemed to be a contract made

that no broker or  finder  has been  employed  or  engaged  by either of them in
connection  with the  transactions  contemplated  in this Agreement and that all
negotiations  relative to this Agreement  have been carried on directly  between
the parties hereto without the intervention of any other person.

                                       3

all of the parties to this Agreement. No waiver of any of the provisions of this
Agreement  shall be deemed or shall  constitute a waiver of any other  provision
