      E. Securities Act Representations, Warranties and Understandings. Becker,
Hargrave, N. R. Broussard and Danny Broussard hereby make the following
representations and warranties to OMNI:

            (1)   Accredited Investor. Becker, Hargrave, N. R. Broussard and
                  Danny Broussard represent and warrant that they are each an
                  accredited investor as that term is defined in Rule 501 of
                  Regulation D, and are acquiring the Common Shares solely for
                  their own account as a principal and not with a present view
                  to the public resale or distribution of all or any part
                  thereof, except pursuant to sales that are exempt from the
                  registration requirement of the Securities Act and/or sales
                  registered under the Securities Act; provided, however that in
                  making such representation, neither agrees to hold the Common
                  Shares for any minimum or specific term and reserves the right
                  to sell, transfer or otherwise dispose of the Common Shares at
                  any time in accordance with Federal and state securities laws
                  applicable to such sale, transfer or disposition. Each has the
                  knowledge and experience in business and financial matters so
                  as to enable it to understand the risks of and form an
                  investment decision with respect to its investment in Common
                  Shares.

            (2)   Information. OMNI has made available to Becker, Hargrave, N.
                  R. Broussard and Danny Broussard and their advisors and
                  representatives, if any, information regarding the business,
                  operations and financial condition of OMNI, and has granted to
                  each the opportunity to ask questions of and receive answers
                  from representatives of OMNI, its officers, directors,
                  employees and agents concerning the Company. OMNI answered all
                  of the questions asked by each, their advisors and
                  representatives.

            (3)   Limitations on Disposition. Becker, Hargrave, N. R. Broussard
                  and Danny Broussard acknowledge that the Common Shares have
                  not been and are not currently being registered under the
                  Securities Act and may not be transferred or resold without
                  registration under the Securities Act or unless pursuant to an
                  exemption therefrom.

            (4)   Legend. Becker, Hargrave, N. R. Broussard and Danny Broussard
                  understand that the certificates representing the Common
                  Shares except as



                  set forth below, shall bear at issuance a restrictive legend
                  in substantially the following form:

                        "The securities represented by this certificate have not
                        been registered under the Securities Act of 1933, as
                        amended (the "Securities Act"), or the securities laws
                        of any state, and may not be offered for sale, sold,
                        transferred or assigned unless a registration statement
                        under the Securities Act and applicable state securities
                        laws shall have become effective with regard thereto, or
                        an exemption from registration under the Securities Act
                        and applicable state securities laws is available in
                        connection with such offer or sale."

                  Notwithstanding the foregoing, it is agreed that, as long as
                  (A) the resale or transfer (including without limitation a
                  pledge) of any of the Common Shares is registered pursuant to
                  an effective registration statement, (B) such Common Shares
                  have been sold pursuant to Rule 144 under the Securities Act
                  or any successor provision ("Rule 144"), subject to receipt by
                  OMNI of customary documentation in connection therewith, or
                  (C) such Common Shares are eligible for resale under Rule
                  144(k) or any successor provision, such Common Shares shall be
                  issued without any legend or other restrictive language and,
                  with respect to Common Shares upon which such legend is
                  stamped, OMNI shall issue new certificates with such legend to
                  the holder upon request.

            (5)   Reliance on Exemptions. Becker, Hargrave, N. R. Broussard and
                  Danny Broussard understand that the Common Shares are being
                  offered and sold to it in reliance upon specific exemptions
                  from the registration requirements of United States federal
                  and state securities laws and that OMNI is relying upon the
                  truth and accuracy of the representations and warranties of
                  Becker, Hargrave, N. R. Broussard and Danny Broussard set
                  forth herein in order to determine the availability of such
                  exemptions and the eligibility of Becker, Hargrave, N. R.
                  Broussard and Danny Broussard to acquire the Common Shares.

            (6)   Non-Affiliate Status; Common Stock Ownership. Neither Becker,
                  Hargrave, N. R. Broussard and Danny Broussard is an Affiliate
                  of OMNI. Becker's, Hargrave's, N. R. Broussard's and Danny
                  Broussard's investment in the Common Shares is not for the
                  purpose of acquiring, directly or indirectly, control of, and
                  it has no intent to acquire or exercise control of, the
                  Company or to influence the decisions or policies of OMNI's
                  Board of Directors.



      F. Registration Rights. In addition, and in connection with the issuance
of the Common Shares described above, OMNI warrants and represents that if for
any reason, OMNI causes a registration statement to be filed with the intention
of satisfying the requirements of the Securities and Exchange Act of 1933 for
the purpose of authorizing the issuance of any additional Common Shares of OMNI,
irrespective of the primary purpose of said issuance of additional Common
Shares, OMNI shall include in said registration statement the 50,000 Common
Shares issued to Becker, the 50,000 Common Shares issued to Hargrave the 50,000
Common Shares issued to N. R. Broussard and the 50,000 Common Shares issued to
Danny Broussard without having Becker, Hargrave, N. R. Broussard and Danny
Broussard incur any costs whatsoever. Notice of filing the registration
statement shall be provided within 7 days of such filing.

      G. Rule 144. Should any party need a Rule 144 Opinion of Counsel letter to
sale or transfer all or any portion of their respective Common Shares, OMNI will
engage securities counsel at its sole cost and expense to render and deliver the
opinion. In addition, OMNI will help facilitate any such transfer or sale by
engaging brokers, to handle the transfer at OMNI's discount brokerage rate, but
such fee is to be paid by the selling party, not OMNI.

      H. Agreement Not to Sue. OMNI agrees to not bring any action against or
otherwise pursue Becker, Hargrave, N. R. Broussard or Danny Broussard for any
breaches under the Agreements. OMNI reserves its rights to sue or otherwise
pursue any and all other parties to the Agreements for breaches thereof. OMNI
agrees to defend, indemnify and hold harmless Becker, Hargrave, N.R. Broussard
and Danny Broussard from and against any action that Edward Laborde and/or Karl
Comeaux might bring against one or more of them under or with respect to the
Agreements.

      I. Confidentiality. The parties hereto agree to keep the terms and
provisions of this Agreement confidential, except that the provisions hereof and
a copy of this Agreement may be provided to GECC, WBCC and their respective
counsel.

      J. Miscellaneous. This Agreement shall be binding upon the heirs, estates,
representatives, successors, and assigns of the parties hereto. This Agreement
shall constitute the entire agreement of the parties hereto relating to the
subject matter hereof. It does not however, affect matters provided for in the
original Agreements that are unaffected by this Agreement. No provision of this
Agreement shall be amended, modified, or waived except as agreed in writing by
the parties hereto. This Agreement shall be construed and enforced in accordance
with the laws of the State of Louisiana. In the event any of the sections,
paragraphs, provisions, sub-paragraphs, or portions thereof of this Agreement
are held to be unenforceable and invalid by any Court of competent jurisdiction,
the validity and enforceability of the remaining sections, paragraphs,
provisions, sub-paragraphs, or portions thereof shall not be affected thereby,
and each term and provision of the Agreement shall be valid and enforceable to
the fullest extent permitted by law. This Agreement is the product of mutual
negotiations between Becker, Hargrave, N. R. Broussard, Danny Broussard, OMNI,
Trussco and Trussco Properties. Becker, Hargrave, N. R, Broussard and Danny
Broussard have obtained the advice of counsel prior to



entering into this Agreement. This Agreement has been negotiated and drafted by
all parties, and if any disagreement shall arise as to the construction or
meaning of this Agreement, the parties hereto agree that the rule of contract
interpretation that documents may be construed against the drafter shall have no
application to this Agreement.

      K. Prevails Party Attorney Fees. If any party has to resort to legal
action in order to enforce any provision of this Agreement, said party, if that
party prevails, is entitled to reasonable attorney's fees to be set by the
court.

      L. Representations and Warranties. Hargrave hereby represents that prior
to the assignment set forth above, he had a 1/3 interest in each of Seller Note
No.1 and Seller Note No. 2 and had not otherwise sold, assigned, encumbered or
pledged any of his interest in such notes to any person or entity. Hargrave
further represents and warrants that he had full right, power and authority to
transfer and assign such interest to Omni Properties Corp. free and clear of all
liens, security interests and encumbrances. Each of Becker, N. R. Broussard and
Danny Broussard represent that he has not sold, assigned, encumbered or pledged
any or all of his interest in Seller Note No. 3. Becker, N. R. Broussard and
Danny Broussard hereby collectively represent and that they have full right,
power and authority to surrender Seller Note No. 3 and accept the obligations of
OMNI set forth herein in full satisfaction of Seller Note No. 3 and further
authorize and direct any attorney holding Seller Note No. 3 on their behalf to
deliver such note to OMNI contemporaneously with the execution of this
Agreement.

      M. Further Assurances. At any time and from time to time, upon the written
request of OMNI, each of Becker, Hargrave, N.R. Broussard and Danny Broussard
agrees that he will promptly and duly execute and deliver any and all such
further instruments and documents and take such further actions as OMNI may deem
desirable to accomplish the surrender, release and satisfaction of Seller Note
No. 3 and the transfer and assignment of Hargrave's 1/3 interest in Seller Note
No. 1 and Seller Note No. 2.
