governmental or regulatory authority, agency, commission, body or other
governmental entity, in connection with the execution and delivery of this
Agreement by Centra or the carrying out and consummation of any transactions

         applicable state laws and its certificate of incorporation, by-laws and

         suffered in connection with any claim action, suit, proceeding or
         investigation, whether civil, criminal or administrative, arising out
         of matters existing or occurring prior to the Closing, whether asserted
         or claimed prior to, at or after the Closing, which is based in whole
         or in part on, or arising in whole or in part out of the fact that such
         person is or was a director or officer of Rako including, without
         limitation, all losses, claims, damages, costs, expenses, liabilities,
         judgments or settlement amounts based in whole or in part on, or
         arising in whole or in part out of, or pertaining to this Agreement or
         the transactions contemplated hereby to the fullest extent that Centra
         could have been permitted under applicable state laws and its
         certificate of incorporation, by-laws and other agreements in effect on
         the date hereof to indemnify such individual. Notwithstanding the
         foregoing, no indemnity shall be provided to Centra or any such
         Shareholder, director or officer in respect of the following:

                  (i) any matter alleging a breach of Centra's representations,
                  warranties and/or covenants in this Agreement; or

                  (ii) any matter alleging the Shareholder, director or officer
                  willfully acted in violation of his duty under applicable law.

         (c) Any indemnified party wishing to claim indemnification under
         subsection (a) or (b) of this Section 6.4, upon leaning of any such
         claim, action , suit, proceeding or investigation, will promptly notify
         Centra if under subsection (a), or Rako if under subsection (b), but
         failure to so notify the appropriate party will not relieve the
         indemnifying party from any liability which it may have under this
         Section 6.4 except to the extent such failure materially prejudices
         such party. In the event of any such claim, action, suit, proceeding or
         investigation, (i) the indemnifying party will have the right to assume
         the defense thereof and will not be liable to any such indemnified
         party in connection with the defense thereof, (ii) the indemnified
         party will cooperate in all respects as requested by the indemnifying
         party in the defense of any such matter, and (iii) the indemnifying
         party will not be liable for any settlement effected without its prior
         written consent, which consent will not be unreasonably withheld;
         provided, however, that the indemnifying party will not have any
         obligation hereunder to any indemnified party if and when a court will
         ultimately determine, and such determination will have

                                      -14-
<PAGE>

         become final, that the indemnification of such indemnified party in the
         manner contemplated hereby is prohibited by law.

SECTION 6.5. Confidentiality. All parties hereto agree to keep confidential this
Agreement and all information and documents relating to this Agreement until
such time as the Agreement and the transactions contemplated hereunder are made
public by means of an appropriate press release or by any other means reasonably
assured to make such information publicly available.

Osprey Investments II, Inc.
1050 Riverside Avenue
Jacksonville, FL 32204
Attn.  D. Robert Murphy, Jr., President

Re: Contribution of Shares

Gentlemen:

         By this agreement Osprey Investments II, Inc. ("Osprey") agrees to
contribute to the Company shares of its common stock, par value $0.001 per share
(the "Shares") in the amount set forth next to Osprey's name on the attached
Schedule A, in accordance with, and subject to, the terms and conditions
described below.

1.0      OSPREY'S REPRESENTATIONS

         Osprey hereby represents, warrants and acknowledges to, and agrees
with, the Company as follows:

         1.1 Osprey is the principal shareholder of RAKO Capital Corporation
(the "Company") and has access to all of the Company's books and records and
information relevant to its decision to contribute the Shares on the terms of
this Agreement. Osprey has carefully considered and has, to the extent Osprey
believes such discussion necessary, discussed with its own professional legal,
tax, accounting, and financial advisers the suitability of contributing the
Shares in view of Osprey's particular tax, legal and financial situation.

         1.2 Osprey acknowledges that all documents, records, and books
pertaining to its decision to contribute the Shares which Osprey has requested
have been made available for its inspection or inspection by its attorney(s),
accountant(s), or adviser(s).

         1.3 Osprey and/or its adviser(s) has/have had a reasonable opportunity
to ask questions of, and receive answers from, a person or persons acting on
behalf of the Company concerning the Company's business and financial affairs
and the Shares and all such questions have been answered to Osprey's full
satisfaction.

         1.4 Osprey or its investment advisor, as the case may be, have such
knowledge and experience in financial, tax, legal, and business matters so as to
enable Osprey to utilize the

                                                                               1
<PAGE>

information made available to it in connection with its contribution of the
Shares, and to make an informed decision with respect thereto.

         1.5 Osprey agrees to surrender for cancellation certificates
representing presently outstanding shares registered in its name (as set forth
in the attached Schedule A) and, if the number of shares represented by that
certificate exceeds the number being surrendered for cancellation, to accept a
new certificate for the number of shares retained by Osprey after contributing
the agreed number of Shares (as set forth in the attached Schedule A). Osprey
acknowledges that the certificates representing the Shares shall be stamped or
otherwise imprinted with a legend substantially in the following form and that
the Company may issue stop transfer instructions to the transfer agent of such
securities:

         "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
         UNITED STATES FEDERAL OR STATE SECURITIES LAWS AND MAY NOT BE OFFERED
         FOR SALE, SOLD, OR OTHERWISE DISPOSED OF OR ASSIGNED FOR VALUE,
         DIRECTLY OR INDIRECTLY, NOR MAY ANY OF THE FOREGOING SECURITIES BE
         TRANSFERRED ON THE BOOKS OF THE CORPORATION, WITHOUT REGISTRATION OF
         SUCH SECURITIES UNDER ALL APPLICABLE UNITED STATES FEDERAL AND STATE
         SECURITIES LAWS OR COMPLIANCE WITH AN APPLICABLE EXEMPTION THEREFROM.
         SUCH COMPLIANCE (AT THE OPTION OF THE CORPORATION) SHALL BE EVIDENCED
         BY AN OPINION OF COUNSEL TO THE HOLDER THEREOF, IN FORM AND SUBSTANCE
         ACCEPTABLE TO THE CORPORATION, THAT NO VIOLATION OF SUCH REGISTRATION
         PROVISIONS WOULD RESULT FROM ANY PROPOSED TRANSFER OR ASSIGNMENT."

         1.6 Osprey will not sell or otherwise transfer any Shares without
registration under the Securities Act of 1933, as amended (the "Securities
Act"), or applicable state securities laws or an exemption therefrom. Osprey
understands that the Shares have not been registered under the Securities Act or
under the securities laws of any state. Osprey represents that it has acquired
and are holding the Shares for its own account, for investment, and not with a
view to resale or distribution, except in compliance with the Securities Act.
Osprey has not offered or sold any portion of the Shares held by it nor does it
have any present intention of dividing such Shares with others or of selling,
distributing, or otherwise disposing of any portion of such Shares either
currently or after the passage of a fixed or determinable period of time or upon
the occurrence or non-occurrence of any predetermined event or circumstance in
violation of the Securities Act.

         1.7 Osprey agrees to indemnify and hold harmless the Company, and each
officer, director, employee, agent, representative or control person thereof,
who is or may be a party to, or is or may be threatened to be made a party to,
any threatened, pending, or completed action, suit, or proceeding, whether
civil, criminal, administrative, or investigative, by reason of, or arising
from, any actual or alleged misrepresentation or misstatement of facts or
omission to represent or state facts made or alleged to have been made by Osprey
to the Company or any agent or representative thereof, or omitted or alleged to
have been omitted by Osprey, concerning Osprey's authority to contribute the

                                                                               2
<PAGE>

Shares, including, without limitation, any such misrepresentation, misstatement,
or omission contained in any document submitted by Osprey against losses,
liabilities, and expenses (including reasonable attorneys' fees, judgments,
fines, and amounts paid in settlement) actually and reasonably incurred by the
Company, or other such indemnified person in connection with such action, suit,
or proceeding, for which the Company, or other such indemnified person, has not
otherwise been reimbursed.

2.0      UNDERSTANDINGS.

         Osprey understands, acknowledges, and agrees with the Company as
follows:

         2.1 Osprey's contribution of the Shares to the Company and acceptance
of a new certificate for the Shares retained by it is intended to be exempt from
registration under the Securities Act of 1933, as amended (the "Securities
Act"), and the Florida Securities Act, which is in part dependent upon the
truth, completeness, and accuracy of the statements made by Osprey.

         2.2 Insofar as indemnification for liabilities under the Securities Act
may be permitted to directors, officers or controlling persons of the Company,
the Company has been informed that, in the opinion of the Securities and
Exchange Commission, such indemnification is against public policy as expressed
in the Securities Act and is therefore unenforceable to such extent.

         2.3 IN MAKING ITS DECISION TO CONTRIBUTE THE SHARES, OSPREY MUST RELY
ON ITS OWN EXAMINATION OF THE COMPANY AND THE CONTRIBUTION, INCLUDING THE MERITS
AND RISKS INVOLVED. THE SHARES HAVE NOT BEEN RECOMMENDED BY ANY FEDERAL OR STATE
SECURITIES COMMISSION OR REGULATORY AUTHORITY. FURTHERMORE, THE FOREGOING
AUTHORITIES HAVE NOT CONFIRMED THE ACCURACY OR DETERMINED THE ADEQUACY OF THIS
DOCUMENT. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

3.0      MISCELLANEOUS.

         3.1 Notices required or permitted to be given hereunder shall be in
writing and shall be deemed to be sufficiently given when personally delivered
or sent by registered mail, return receipt requested, addressed: (i) if to the
Company, at RAKO Capital Corporation., Two North College Avenue, Fayetteville,

Ray A. Mantle, Esq. or (ii) if to Osprey, at the address appearing on the
Company's records, or at such other address as may have been specified by
written notice given in accordance with this Section 3.1.

         3.2 Failure of Osprey or the Company to exercise any right or remedy
under this Agreement or any other agreement between the Company and Osprey, or
otherwise, or delay by Osprey or the Company in exercising such right or remedy,
