2.       Interest Rate

         This Note shall bear interest from the date of this Note until maturity
         at the rate of 6% per annum and thereafter at the rate provided in Item
         5.

3.       Dredging and Deep Water Pier Construction Agreement

         This Note is being issued pursuant to that certain Dredging and
         Deepwater Pier Construction Agreement and all exhibits thereto between
         Maker and Payee dated April 3, 1987 (the "Agreement") and all other
         amendments thereto (the "Amendments"). This Note consolidates and
         replaces the promissory notes listed in Exhibit A to this Promissory
         Note. It is expressly understood and agreed that the terms of this Note
         are subject to the terms of the Agreement and the Amendments. Terms
         defined in the Agreement and the Amendments shall have the same meaning
         when used herein. In the case of any conflict this Note shall prevail.

4.       Events of Default

         The unpaid balance of the Note, including principal and accrued
         interest, shall at the option of Payee become immediately due and
         payable upon the occurrence of any one or more of the following events
         ("Events of Default"), regardless of the cause thereof and whether
         within or beyond the control of the Maker:

         (a)      The failure of Maker to pay any sum due under this Note within
                  60 days after notice to Maker that a payment has not been made
                  when due.

                  this Note.

5.       Default Rate of Interest

         From and after the occurrence and during the continuation of any Event
         of Default, regardless of whether Payee also elects to accelerate the
         maturity of the Note, at Payee's sole option the unpaid balance of the
         Note shall bear interest at 10% (the "Default Rate"); provided,
         however, that after judgment all such sums shall bear interest at the
         greater of the Default Rate or the rate prescribed by applicable law
         for judgments. All interest which accrues at the Default Rate shall be
         due and payable on Payee's demand from time to time.

6.       Rights and Remedies of Payee

         Payee shall be entitled to pursue any and all rights and remedies
         provided by applicable law and/or under the terms of this Note, all of
         which shall be cumulative and may be exercised successively or
         concurrently. Payee's delay in exercising or failure to exercise any
         rights or remedies to which Payee may be entitled if any Event of
         Default occurs shall not constitute a waiver of any of Payee's rights
         or remedies with respect to that or any subsequent Event of Default,
         whether of the same or a different nature, nor shall any single or
         partial exercise of any right or remedy by Payee preclude any other or
         further exercise of that or any other right or remedy. No waiver of any
         right or remedy by Payee shall be effective unless made in writing and
         signed by Payee, nor shall any waiver on one occasion apply to any
         future occasion, but shall be effective only with respect to the
         specific occasion addressed in that signed writing.

7.       Waiver and Consent

         To the fullest extent permitted by law Maker hereby: (a) waives demand,
         presentment, protest, notice of dishonor, suit against or joinder of
         any other person, and all other requirements necessary to charge or
         hold Maker liable with respect to the Note (except as otherwise
         expressly set forth herein); (b) waives any right to interpose any
         set-off or counterclaim or to plead any statute of limitations as a
         defense in any such action or proceeding. No provision of this Note
         shall limit Payee's right to serve legal process in any manner
         permitted by law or to bring any such action or proceeding in any
         competent jurisdiction. Until Payee receives all sums due under this
         Note in immediately available funds, Maker shall not be released from
         liability with respect to the Note unless Payee expressly releases
         Maker in a writing signed by Payee.

8.       Costs, Indemnities and Expenses

         Maker agrees to pay all filing fees and similar charges and all costs
         incurred by Payee in collection or securing or attempting to collect or
         secure the Note, including reasonable attorney's fees, whether or not
         involving arbitration, litigation and/or appellate or administrative
         proceedings. Maker agrees to pay any documentary stamp taxes,
         intangible taxes, withholding tax or other taxes which may now or
         hereafter apply to any payment made in respect of the Note, and Maker
         agrees to indemnify and hold Payee harmless from and against any
         liability, reasonable costs, reasonable attorney's fees, penalties,
         interest or expenses relating to any such taxes, as and when the same
         may be incurred.

9.       Maximum Interest Rate

         In no event shall any agreed to or actual exaction charged, reserved or
         taken as an advance or forbearance by Payee as consideration for the
         Note exceed the limits (if any) imposed or provided by the law
         applicable from time to time to the Note for the use or detention of
         money or for forbearance in seeking its collection; Payee hereby waives
         any right to demand such excess. In the event that the interest
         provisions of this Note or any exactions provided for in this Note
         shall result at any time or for any reason in an effective rate of
         interest that transcends the maximum interest rate permitted by
         applicable law (if any), then without further agreement or notice the
         obligation to be fulfilled shall be automatically reduced to such limit
         and all sums received by Payee in excess of those lawfully collectible
         as interest shall be applied against the principal of the Note
         immediately upon Payee's receipt thereof, with the same force and
         effect as though the Maker had specifically designated such extra sums
         to be applied to principal and Payee had agreed to accept such extra
         payment(s) as a premium-free prepayment or prepayments. During any time
         that the Note bears interest at the maximum lawful rate (whether by
         application of this paragraph, the Default Rate provisions of this Note
         or otherwise), interest shall be computed on the basis of the actual
         number of days elapsed and a year of 360 days.

10.      Governing Law

         The Note shall be governed by, and construed and enforced in accordance
         with, the laws of Antigua and Barbuda, W.I., as currently in effect and
         subject to the principles of public international law. Antigua hereby
         irrevocably and unconditionally waives any and all defenses it may have
         based in whole or in part upon the doctrine of sovereign immunity.

11.      Severability

         Any provision of this Note which is prohibited or unenforceable in any
         jurisdiction shall, as to such jurisdiction only, be ineffective only
         to the extent of such prohibition or unenforceability without
         invalidating the remaining provisions hereof or affecting the validity
         or enforceability of such provision in any other jurisdiction.

12.      Interpretation

         The term "Payee" shall be deemed to include any subsequent holder(s) of
         this Note. Whenever used in this Note, words in the singular include
         the plural, words in the plural include the singular, and pronouns of
         any gender include the other genders, all as may be appropriate.
         Captions and paragraph headings in this Note are for convenience of
         reference only and shall not affect its interpretation.

13.      Miscellaneous

         Time shall be of the essence with respect to the terms of this Note.
         This Note cannot be changed or modified orally. This Note may be
         prepaid in whole or in part at any time without penalty. Unless
         otherwise provided in the Agreement, no prepayment need include imputed
         interest not accrued through the date of prepayment, and no imputed
         interest shall accrue thereafter on any amount prepaid. In furtherance
         of the above, except as otherwise required by law or by the provisions
         of this Note or designated by Payee, payments received by Payee
         hereunder shall be applied first against interest accrued on the Note,
         and next in reduction of the remaining balance of the Note, except that
         during the continuance of any Event of Default Payee may apply such
         payments in any order to priority determined by Payee in its exclusive
         judgement. Except as otherwise required by the provisions of this Note
         or designated by Payee, any notice required to be given to Maker shall
         be deemed sufficient if made personally or if mailed, postage prepaid,
         to Maker's address as it appears on the signature page of this Note (as
         the same may hereinafter be changed by written notice to Payee from
         Maker).

THIS NOTE IS SIGNED, SEALED, AND DELIVERED AS OF THE DATE FIRST WRITTEN ABOVE BY
AND THROUGH ITS SIGNATORY DULY AUTHORIZED.

         This Note shall bear interest from the date of this Note until maturity
         at the rate of 6% per annum and thereafter at the rate provided in Item
         5.

3.       Dredging and Deep Water Pier Cconstruction Agreement

         This Note is being issued pursuant to that certain Dredging and
         Deepwater Pier Construction Agreement and all exhibits thereto between
         Maker and Payee dated April 3, 1987 (the "Agreement") and all other
         amendments thereto (the "Amendments"). This Note consolidates and
         replaces the promissory notes listed in Exhibit A to this Promissory
         Note. It is expressly understood and agreed that the terms of this Note
         are subject to the terms of the Agreement and the Amendments. Terms
         defined in the Agreement and the Amendments shall have the same meaning
         when used herein. In the case of any conflict this Note shall prevail.

4.       Events of Default

         The unpaid balance of the Note, including principal and accrued
         interest, shall at the option of Payee become immediately due and
         payable upon the occurrence of any one or more of the following events
         ("Events of Default"), regardless of the cause thereof and whether
         within or beyond the control of the Maker:

         (a)      The failure of Maker to pay any sum due under this Note within
                  60 days after notice that a payment has not been made when
                  due.

                  this Note.

5.       Default Rate of Interest

         of Default, regardless of whether Payee also elects to accelerate the
         maturity of the Note, at Payee's sole option the unpaid balance of the
         Note shall bear interest at 10% (the "Default Rate"); provided,
         however, that after judgment all such sums shall bear interest at the
         greater of the Default Rate or the rate prescribed by applicable law
         for judgments. All interest which accrues at the Default Rate shall be
         due and payable on Payee's demand from time to time.

6.       Rights and Remedies of Payee

         Payee shall be entitled to pursue any and all rights and remedies
         provided by applicable law and/or under the terms of this Note, all of
         which shall be cumulative and may be exercised successively or
         concurrently. Payee's delay in exercising or failure to exercise any
         rights or remedies to which Payee may be entitled if any Event of
         Default occurs shall not constitute a waiver of any of Payee's rights
         or remedies with respect to that or any subsequent Event of Default,
         whether of the same or a different nature, nor shall any single or
         partial exercise of any right or remedy by Payee preclude any other or
         further exercise of that or any other right or remedy. No waiver of any
         right or remedy by Payee shall be effective unless made in writing and
         signed by Payee, nor shall any waiver on one occasion apply to any
         future occasion, but shall be effective only with respect to the
         specific occasion addressed in that signed writing.

7.       Waiver and Consent

         To the fullest extent permitted by law Maker hereby: (a) waives demand,
         presentment, protest, notice of dishonor, suit against or joinder of
         any other person, and all other requirements necessary to charge or
         hold Maker liable with respect to the Note (except as otherwise
         expressly set forth herein); (b) waives any right to interpose any
         set-off or counterclaim or to plead any statute of limitations as a
         defense in any such action or proceeding. No provision of this Note
         shall limit Payee's right to serve legal process in any manner
         permitted by law or to bring any such action or proceeding in any
         competent jurisdiction. Until Payee receives all sums due under this
         Note in immediately available funds, Maker shall not be released from
         liability with respect to the Note unless Payee expressly releases
         Maker in a writing signed by Payee.

8.       Costs, Indemnities and Expenses

         Maker agrees to pay all filing fees and similar charges and all costs
         incurred by Payee in collection or securing or attempting to collect or
         secure the Note, including reasonable attorney's fees, whether or not
         involving arbitration, litigation and/or appellate or administrative
         proceedings. Maker agrees to pay any documentary stamp taxes,
         intangible taxes, withholding tax or other taxes which may now or
         hereafter apply to any payment made in respect of the Note, and Maker
         agrees to indemnify and hold Payee harmless from and against any
         liability, reasonable costs, reasonable attorney's fees, penalties,
         interest or expenses relating to any such taxes, as and when the same
         may be incurred.

9.       Maximum Interest Rate

         In no event shall any agreed to or actual exaction charged, reserved or
         taken as an advance or forbearance by Payee as consideration for the
         Note exceed the limits (if any) imposed or provided by the law
         applicable from time to time to the Note for the use or detention of
         money or for forbearance in seeking its collection; Payee hereby waives
         any right to demand such excess. In the event that the interest
         provisions of this Note or any exactions provided for in this Note
         shall result at any time or for any reason in an effective rate of
         interest that transcends the maximum interest rate permitted by
         applicable law (if any), then without further agreement or notice the
         obligation to be fulfilled shall be automatically reduced to such limit
         and all sums received by Payee in excess of those lawfully collectible
         as interest shall be applied against the principal of the Note
         immediately upon Payee's receipt thereof, with the same force and
         effect as though the Maker had specifically designated such extra sums
         to be applied to principal and Payee had agreed to accept such extra
         payment(s) as a premium-free prepayment or prepayments. During any time
         that the Note bears interest at the maximum lawful rate (whether by
         application of this paragraph, the Default Rate provisions of this Note
         or otherwise), interest shall be computed on the basis of the actual
         number of days elapsed and a year of 360 days.

10.      Governing Law

         The Note shall be governed by, and construed and enforced in accordance
         with, the laws of Antigua and Barbuda, W.I., as currently in effect and
         subject to the principles of public international law. Antigua hereby
         irrevocably and unconditionally waives any and all defenses it may have
         based in whole or in part upon the doctrine of sovereign immunity.

11.      Severability

         Any provision of this Note which is prohibited or unenforceable in any
         jurisdiction shall, as to such jurisdiction only, be ineffective only
         to the extent of such prohibition or unenforceability without
         invalidating the remaining provisions hereof or affecting the validity
         or enforceability of such provision in any other jurisdiction.

12.      Interpretation

         The term "Payee" shall be deemed to include any subsequent holder(s) of
         this Note. Whenever used in this Note, words in the singular include
         the plural, words in the plural include the singular, and pronouns of
         any gender include the other genders, all as may be appropriate.
         Captions and paragraph headings in this Note are for convenience of
         reference only and shall not affect its interpretation.

13.      Miscellaneous

         Time shall be of the essence with respect to the terms of this Note.
         This Note cannot be changed or modified orally. This Note may be
         prepaid in whole or in part at any time without penalty. Unless
         otherwise provided in the Agreement, no prepayment need include imputed
         interest not accrued through the date of prepayment, and no imputed
         interest shall accrue thereafter on any amount prepaid. In furtherance
         of the above, except as otherwise required by law or by the provisions
         of this Note or designated by Payee, payments received by Payee
         hereunder shall be applied first against interest accrued on the Note,
         and next in reduction of the remaining balance of the Note, except that
         during the continuance of any Event of Default Payee may apply such
         payments in any order to priority determined by Payee in its exclusive
         judgement. Except as otherwise required by the provisions of this Note
         or designated by Payee, any notice required to be given to Maker shall
         be deemed sufficient if made personally or if mailed, postage prepaid,
         to Maker's address as it appears on the signature page of this Note (as
         the same may hereinafter be changed by written notice to Payee from
         Maker).

THIS NOTE IS SIGNED, SEALED, AND DELIVERED AS OF THE DATE FIRST WRITTEN ABOVE BY
AND THROUGH ITS SIGNATORY DULY AUTHORIZED.
