NO SUCH SALE OR DISPOSITION MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION

                             STOCK OPTION AGREEMENT

         Calton, Inc., a New Jersey corporation (the "Company") hereby grants to
Steven R. Tetreault (the "Optionee") the option (the "Option") to purchase one
hundred thousand (100,000) shares (the "Shares") of the Company's Common Stock,
$.01 par value (the "Common Stock") at the price determined as provided herein.
The Option may be exercised in whole or in part.

1.       NATURE OF THE OPTION. This Option is not intended to qualify for any
         special tax benefits to the Optionee and is not intended to qualify as
         an incentive stock option under Section 422 of the Internal revenue
         Code of 1986.

2.       EXERCISE PRICE. The exercise price is Four and 02/100 Dollars ($4.02)
         per share (the "Exercise Price").

3.       METHOD OF EXERCISE. The Option shall not become exercisable until the
         six month anniversary of the Date of Grant (as set forth below). The
         Option shall thereafter be exercisable by written notice (a "Notice of
         Exercise of Stock Option") in the form attached hereto as Exhibit A.
         The Notice of Exercise of Stock Option shall be signed by Optionee and
         shall be delivered in person or by certified mail to the President,
         Secretary or Chief Financial Officer of the Company, or to such other
         agent as the Company shall designate in writing to the Optionee, and
         shall be accompanied by payment of the Exercise Price. The Option shall
         be deemed to be exercised upon receipt by the Company of the executed
         Notice of Exercise of Stock Option accompanied by payment of the
         Exercise Price. Payment of the Exercise Price may be made by cash or
         check.

         The Shares will not be transferred pursuant to the exercise of the
         Option unless such transfer and such exercise shall comply with all
         relevant provisions of law, including federal and state securities
         laws. Assuming such compliance, for income tax purposes the Shares
         shall be considered transferred to the Optionee on the date on which
         the Option is exercised.

4.       REPRESENTATIONS; RESTRICTIONS ON TRANSFER.

         (a)      By receipt of the Option, by its execution and by its
                  exercise, the Optionee represents to the Company the
                  following:



   2

                  (i)      The Optionee understands that the Option and the
                           Shares purchased upon its exercise are securities,
                           the issuance of which requires compliance with
                           federal and state securities laws.

                  (ii)     The Optionee is aware of the Company's business
                           affairs and has acquired sufficient information about
                           the Company to reach an informed and knowledgeable
                           decision to acquire the Company's securities. The
                           Optionee is acquiring the Company's securities for
                           investment for the Optionee's own account only and
                           not with a view to, or for resale in connection with,
                           any "distribution" thereof within the meaning of the
                           Securities Act of 1933, as amended (the "Securities
                           Act").

                  (iii)    The Optionee acknowledges and understands that the
                           Company's securities constitute "restricted
                           securities" under the Securities Act and must be held
                           indefinitely unless they are subsequently registered
                           under the Securities Act or an exemption from such
                           registration is available. The Optionee further
                           acknowledges and understands that the Company is
                           under no obligation to register securities. The
                           Optionee further acknowledges and understands that
                           any certificate evidencing the issuance of the
                           Company's securities to the Optionee will be
                           imprinted with a legend which prohibits the transfer
                           of such securities unless they are registered or such
                           registration is not required in the opinion of
                           counsel satisfactory to the Company and they are
                           transferred in accordance with the provisions set
                           forth below, and with any other legend required under
                           applicable state securities laws.

         (b)      The Company has the requisite power and authority to execute
                  and deliver this Option Agreement (this "Agreement") and to
                  perform its obligations hereunder and to sell, assign,
                  transfer and convey the Shares to the Optionee upon the due
                  exercise of the Option.

5.       NON-TRANSFERABILITY OF OPTION. The Option may not be transferred in any
         manner other than by will or by the laws of descent or distribution and
         may be exercised (i) during the lifetime of the Optionee by the
         Optionee only and (ii) after the death of the Optionee, by those who
         take under Optionee's will or by the laws of descent or distribution.
         The terms of this Agreement shall be binding upon the executors,
         administrators, heirs, successors and permitted assigns of the
         Optionee.

6.       TERM OF OPTION. The Option shall not terminate until the five (5) year
         anniversary of the Date of Grant (as provided below), and may be
         exercised during such term only in accordance with the terms of this
         Agreement.

7.       TAX CONSEQUENCES. The Optionee has reviewed with the Optionee's own tax
         advisors the federal, state, local and foreign tax consequences of the
         transactions contemplated by this Agreement. The Optionee is relying
         solely on such advisors and not on any statements or representations of
         the Company or any of its agents. The Optionee understands that the



                                       2
   3

         Optionee (and not the Company) shall be responsible for any tax
         liability of the Optionee that may arise as a result of the
         transactions contemplated by this Agreement.

8.       STOCK DIVIDENDS, RECLASSIFICATION AND RECAPITALIZATION. In case the
         Company shall (i) pay a dividend or make a distribution on all of its
         outstanding shares of Common Stock in shares of Common Stock, (ii)
         subdivide, reclassify or recapitalize its outstanding Common Stock into
         a greater number of shares or (iii) combine, reclassify or recapitalize
         its outstanding Common Stock into a smaller number of shares, the
         Exercise Price in effect at the time of the record date for such
         dividend or distribution or on the effective date of such subdivision,
         combination, reclassification or recapitalization shall be
         proportionately adjusted (but in no event shall the aggregate Exercise
         Price for all of the shares of Common Stock subject to this Option be
         in excess of $402,000) and the Optionee, upon the exercise of this
         option after such date, shall be entitled to receive the aggregate
         number and kind of shares which, if this Option had been exercised
         immediately prior to such time, he would have owned upon such exercise
         and been entitled to receive upon such dividend, subdivision,
         combination, reclassification or recapitalization. Such adjustment
         shall be made successively whenever any event listed in this Section 8
         shall occur.

9.       PURCHASE RIGHTS UPON MERGER, CONSOLIDATION, ETC. In case of any
         consolidation of the Company with or merger of the Company into another
         corporation or in case of any sale or conveyance to another corporation
         of the property of the Company as an entirety or substantially as an
         entirety, the surviving corporation, if other than the Company,
         resulting therefrom or the acquiring corporation, as the case may be,
         shall assume by written agreement the obligation to deliver, upon
         exercise of this Option and payment of the Exercise Price in effect
         immediately prior to such corporate event, the kind and amount of
         shares or other securities and property which the Optionee would have
         owned or have been entitled to receive after the happening of such
         consolidation, merger, sale or conveyance had this Option been
         exercised immediately prior thereto.

10.      FRACTIONAL INTERESTS. The Company shall not be required to issue
         fractional Shares on the exercise of this Option. If any fraction of a
         Share would, except for the provisions of this Section 10, be issuable
         on the exercise of this Option (or specified portion hereof), then the
         Company shall elect, at its option to either (i) round such fractional
         Share upwards to the nearest whole Share or (ii) pay to the holder an
         amount in cash equal to such fraction multiplied by the then current
         fair value of a Share, determined as follows:

         (a)      If the Common Stock is listed on a national securities
                  exchange or admitted to unlisted trading privileges on such
                  exchange, the current fair value shall be the last reported
                  sale price of the Common Stock on such exchange on the last
                  business day prior to the date of exercise of this Option or
                  if no such sale is made on such day, the average of the
                  closing bid and asked prices for such day on such exchange; or

         (b)      If the Common Stock is not so listed or admitted to unlisted
                  trading privileges, the current fair value shall be the mean
                  of the last reported bid and asked prices reported by the
                  Nasdaq Stock Market (or, if not so quoted on the Nasdaq Stock



                                       3
   4

                  Market, by the NASD Electronic Bulletin Board) on the last
                  business day prior to the day of the exercise of this Warrant;
                  or

(c)               If the Common Stock is not so listed or admitted to unlisted
                  trading privileges and bid and asked prices are not so
                  reported, the current value shall be an amount determined in
                  such reasonable manner as may be prescribed by the Board of
                  Directors of the Company, such determination to be final and
                  binding on the Holder.

11.      REGISTRATION. The Company agrees to register the Shares on Form S-8
         under the Securities Act of 1933 within six (6) months from the Date of
         Grant.

         Boulevard, Vero Beach, Florida 32960, and any notice to be given to the

         with written notice of such change pursuant to the provisions of this
         Section 12. Any notice hereunder shall be deemed duly given to the
         party to whom such notice is addressed when delivered personally, when
         delivery is refused, when delivered by overnight courier service of
         national reputation providing receipted delivery, or two (2) days after
         being mailed by certified mail, return receipt requested.

         and enforced in accordance with the laws of the State of New Jersey
         other than any choice of law rules calling for the application of laws
