     Loan  Agreement,  any payment made using other than a Fleet  National  Bank
     check  or wire  transfer,  there  is an  automatic  delay of one (1) day in
     posting the "payment" (as such term is defined  below)  because the payment
     is not considered to be in "immediately available funds."

2.   Payments. All payments shall be made by Borrowers to Bank at 208 Harristown
     --------
     Road, Glen Rock, New Jersey 07452 or such other place as Bank may from time
     to time  specify  in  writing in lawful  currency  of the United  States of
     America in immediately  available funds, without counterclaim or setoff and
     free and clear of, and without any deduction or withholding  for, any taxes
     or other payments.

3.   Application of Payments. All payments shall be applied first to the payment
     -----------------------
     of all  fees,  expenses  and  other  amounts  due to  the  Bank  (excluding
     principal  and  interest),  then to accrued  interest,  and the  balance on
     account of outstanding  principal;  provided,  however, that after default,
     payments  will be applied to the  obligations  of Borrowers to Bank as Bank
     determines in its sole discretion.

4.   Payment of Fees and Expenses.  Borrowers shall pay on demand all reasonable
     ----------------------------
     expenses  of Bank  in  connection  with  the  preparation,  administration,
     default,  collection,  waiver or amendment of the Loan Agreement and/or any
     of the Loan Documents, or in connection with Bank's exercise,  preservation
     or  enforcement  of any of  its  rights,  remedies  or  options  hereunder,
     including, without limitation,  reasonable fees of outside legal counsel or
     the  allocated  reasonable  costs of in-house  legal  counsel,  accounting,

     any  reasonable  fees or  expenses  associates  with  travel or other costs
     relating to any appraisals or examinations conducted in connection with the
     Loan  Agreement,  any of the Loan  Documents  and/or any of the  Collateral
     and/or  the Term Loan  Collateral  and the  amount  of all such  reasonable
     expenses  shall,  until  paid,  bear  interest  at the rate  applicable  to
     principal  thereunder  (including  the default  rate) and be an  obligation
     secured by all of the Collateral and the Term Loan Collateral.

5.   Interest  Computation.  All  computations  of interest shall be made on the
     ---------------------
     basis of a three hundred sixty (360) day year and the actual number of days

6.   Following Business Day Convention.  At all times throughout the term of the
     ---------------------------------
     Loan  Agreement and the other Loan  Documents,  the payment dates should be
     adjusted in accordance  with the "Following  Business Day  Convention,"  as
     hereinafter defined. The Following Business Day Convention shall be used to
     adjust any relevant date if that date would otherwise fall on a day that is
     not a Business Day. For the purposes herein,  the term "Following  Business
     Day Convention"  shall mean that an adjustment will be made if any relevant
     date would  otherwise  fall on a day that is not a Business Day so that the
     date will be the first  following  day that is a Business  Day. A "Business
     Day" means,  in respect of any date that is specified in the Loan Agreement
     to be subject to adjustment in accordance  with the Following  Business Day
     Convention,  a day on which commercial banks settle payments (i) in London,
     if the payment  obligation is calculated by reference to the LIBOR Rate, or
     (ii) New York, if the payment  obligation is calculated by reference to the
     Base Rate. All payments  hereunder shall be adjusted in accordance with the
     Following Business Day Convention.

7.   Default  Interest Rate.  Upon an Event of Default  (whether or not the Bank
     ----------------------
     has  accelerated  payment of the Revolving  Credit Note, the Line of Credit
     Note, and/or the Term Note), the Borrowers' right to select pricing options
     shall  cease,  and the  amounts  outstanding  under said  notes  shall bear
     interest,  payable on demand,  at a rate, per annum,  determined on a daily
     basis,  of five (5%)  percent in excess of the Base  Rate,  but in no event
     more than the highest rate permitted by the applicable usury law in respect
     of the Borrowers, until the unpaid balance of said notes and interest shall
     have been paid in full.

8.   Replacement  of  Promissory  Note or Other  Documents.  Upon  receipt of an
     -----------------------------------------------------
     affidavit of an officer of the Bank as to the loss,  theft,  destruction or
     mutilation of any promissory  note or any other security  document which is
     not of public record, and in the case of any such loss, theft,  destruction
     or  mutilation,  upon  surrender  and  cancellation  of such  note or other
     document,  Borrowers will issue, in lieu thereof, a replacement  promissory
     note or other security  document in the same  principal  amount thereof and
     otherwise of like tenor.

9.   Pledge to the Federal  Reserve.  The Bank may at any time pledge all or any
     ------------------------------
     portion of its rights under the Loan Documents including any portion of the
     Revolving Credit Note, the Line of Credit Note, and/or the Term Note to any
     of the twelve (12) Federal  Reserve Banks  organized under Section 4 of the
     Federal  Reserve Act, 12 U.S.C.  Section 341. No such pledge or enforcement
     thereof shall release the Bank from its  obligations  under any of the Loan
     Documents.

10.  Late Fee. If the entire amount of any required principal and/or interest is
     --------
     not paid in full  within  ten (10) days  after  the same is due,  Borrowers
     shall pay to Bank a late fee  equal to five  percent  (5%) of the  required
     payment (but in no event more than $2,500.00).

11.  Interest  Limitation.  All agreements  between Borrowers and Guarantors and
     --------------------
     Bank  are  hereby  expressly  limited  so that in no  contingency  or event
     whatsoever,   (whether  by  reason  of  acceleration  of  maturity  of  the
     indebtedness  evidenced hereby or otherwise) shall the amount paid or agree
     to be paid to Bank  for  the  use or the  forbearance  of the  indebtedness
     evidence  hereby exceed the maximum  permissible  under  applicable law.

                                    -10-
<PAGE>

     As used herein,  the term  "applicable law" shall mean the law in effect as
     of the date hereof; provided,  however, that in the event there is a change
     in the law which results in a higher permissible rate of interest, then the
     Revolving  Credit Note, the Line of Credit Note, and the Term Note shall be
     governed by such new law as of its effective  date.  In this regard,  it is
     expressly  agreed  that  it is the  intent  of  Borrowers  and  Bank in the
     execution,  delivery and acceptance of the Revolving  Credit Note, the Line
     of Credit Note, and the Term Note to contract in strict compliance with the
     laws of the State of New Jersey from  time-to-time in effect.  If, under or
     from any circumstances  whatsoever,  fulfillment of any provision hereof or
     of any of the Loan  Documents at the time of  performance of such provision
     shall  be due,  shall  involve  transcending  the  limit  of such  validity
     prescribed by applicable  law,  then the  obligation to be fulfilled  shall
     automatically  be reduced to the limits of such  validity,  and if under or
     from  circumstances  whatsoever  Bank  should  ever  receive as interest an
     amount which would exceed the highest lawful rate,  such amount which would
     be excessive  interest  shall be applied to the  reduction of the principal
     balance evidenced hereby and not to the payment of interest. This provision
     shall control every other  provision of all agreements  between  Borrowers,
     Guarantors and Bank.

12.  Sale of Loan.  The Bank  shall have the  unrestricted  right at any time or
     ------------
     from time to time, and without  Borrowers' or any Guarantor's  consent,  to
     assign all or any portion of its rights and obligations hereunder to one or
     more banks or other  financial  institutions  (each,  an  "Assignee"),  and
     Borrowers and each  Guarantor  agree that they shall execute or cause to be
     executed such documents,  including, without limitation,  amendments to the
     Loan  Agreement  and to any other  documents,  instruments  and  agreements
     executed in connection  herewith as Bank shall deem necessary to effect the
     foregoing.  In  addition,  at the  request  of Bank and any such  Assignee,
     Borrowers shall issue one or more new promissory  notes, as applicable,  to
     any  such  Assignee  and,  if  Bank  has  retained  any of its  rights  and
     obligations  hereunder  following  such  assignment,  to  Bank,  which  new
     promissory  notes shall be issued in  replacement  of, but not in discharge
     of, the liability  evidenced by the  promissory  note held by Bank prior to
     such assignment and shall reflect the amount of the respective  commitments
     and  loans  held by such  Assignee  and Bank  after  giving  effect to such
     assignment.  Upon the  execution  and  delivery of  appropriate  assignment
     documentation,  amendments and any other documentation  required by Bank in
     connection  with such  assignments,  and the  payment  by  Assignee  of the
     purchase price agreed to by Bank and such Assignee,  such Assignee shall be
     a party to the Agreement  and shall have all of the rights and  obligations
     of Bank  hereunder  (and  under  any and all other  guaranties,  documents,
     instruments and agreements  executed in connection  herewith) to the extent
     that such rights and obligations have been assigned by Bank pursuant to the
     assignment  documentation between Bank and such Assignee, and Bank shall be
     released from its  obligations  hereunder and thereunder to a corresponding
     extent. The Bank may furnish any information  concerning the Borrowers to a
     prospective  Assignee(s),   provided  that  the  Bank  shall  require  such
     prospective Assignee to agree in writing to maintain the confidentiality of
     such information.

13.  Right to Sell a Portion of a Loan to a Prospective Participant.  Bank shall
     --------------------------------------------------------------
     have the unrestricted right at any time and from time-to-time,  and without
     the consent of or notice to Borrowers or any Guarantor,  to grant to one or
     more  banks  or  other  financial   institutions  (each,  a  "Participant")
     participating  interests in Bank's  obligation to lend hereunder and/or any
     or all of the loans held by Bank hereunder.  In the event of any such grant

                                      -11-

<PAGE>

     by Bank of a participating  interest to a Participant,  whether or not upon
     notice to Borrowers,  Bank shall remain  responsible for the performance of
     its  obligations  hereunder and Borrowers shall continue to deal solely and
     directly  with  Bank in  connection  with  Bank's  rights  and  obligations
     hereunder.  Bank may furnish any  information  concerning  Borrowers in its
     possession  from  time-to-time to prospective  Participants,  provided that
     Bank shall require any such prospective  Participant to agree in writing to
     maintain the confidentiality of such information.

14.  Setoff.  The Borrowers  and any Guarantor  hereby grant to the Bank a lien,
     ------
     security  interest and right of setoff as security for all  liabilities and
     obligations to the Bank,  whether now existing or hereafter  arising,  upon
     and  against  all  deposits,  credits,  collateral  and  property,  now  or
     hereafter in the possession, custody, safekeeping or control of the Bank or
     any entity under the control of FleetBoston  Financial  Corporation and its
     successors  and assigns,  or in transit to any of them  (collectively,  the
     "Deposits").  In addition to the Bank's common law setoff rights and not in
     limitation  thereof,  at any time  after  the  occurrence  and  during  the
     continuance of an Event of Default,  without demand or notice, the Bank may
     set off the same or any part thereof and apply the same to any liability or
     obligation of the Borrowers  and any  Guarantor  even though  unmatured and
     regardless   of  the  adequacy  of  any  other   collateral   securing  the
     Obligations.  ANY AND ALL RIGHTS TO REQUIRE THE BANK TO EXERCISE ITS RIGHTS
     OR REMEDIES  WITH RESPECT TO ANY OTHER  COLLATERAL  WHICH SECURES THE LOAN,
     PRIOR TO  EXERCISING  ITS RIGHT OF SETOFF  WITH  RESPECT TO SUCH  DEPOSITS,
     CREDITS OR OTHER  PROPERTY OF THE  BORROWERS OR ANY  GUARANTOR,  ARE HEREBY
     KNOWINGLY,  VOLUNTARILY AND IRREVOCABLY  WAIVED. Such right of debit may be
     exercised by the Bank against the Borrowers (and all Guarantors) or against
     any bankruptcy trustee,  debtor-in-possession,  assignee for the benefit of
     creditors,  receiver, or execution, judgment, or attachment creditor of the
     Borrowers (and all Guarantors),  or against anyone else claiming through or
     against the Borrowers (and all Guarantors).

     Furthermore, in the event any attachment,  trustee process, garnishment, or
other levy or lien  (collectively a  "Garnishment")  issues against any Deposits
(the "Liened Funds"),  then the Bank shall have the unconditional right, without
prior notice to the  Borrowers  (and all  Guarantors),  to debit any such Liened
Funds  immediately prior to giving effect to such Garnishment and apply the same
to any  indebtedness of the Borrowers (and all Guarantors) to the Bank under the
Loan Documents, whether or not the same has matured.

     In addition,  without  limiting  any of the  foregoing  rights,  during the
existence  of an Event of  Default  (or any  Default),  the Bank  shall have the
right,  without notice, to "freeze" or segregate any or all of the Deposits such
that the Borrowers (and all  Guarantors) may not access,  control,  or draw upon
them.

                                      -12-

15.  Waiver  of Trial by Jury.  BORROWERS  AND BANK (BY  ACCEPTANCE  OF THE LOAN
     ------------------------
     DOCUMENTS)  MUTUALLY HEREBY KNOWINGLY,  VOLUNTARILY AND INTENTIONALLY WAIVE
     THE RIGHT TO A TRIAL BY JURY IN RESPECT OF ANY CLAIM BASED HEREON,  ARISING
     OUT OF, UNDER OR IN CONNECTION  WITH THE LOAN DOCUMENTS  CONTEMPLATED TO BE
     EXECUTED  IN  CONNECTION  HEREWITH  OR ANY  COURSE  OF  CONDUCT,  COURSE OF
     DEALINGS,  STATEMENTS  (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF ANY PARTY,
     INCLUDING,  WITHOUT LIMITATION,  ANY COURSE OF CONDUCT, COURSE OF DEALINGS,
     STATEMENTS OR ACTIONS OF BANK RELATING TO THE ADMINISTRATION OR ENFORCEMENT
     OF THE LOAN AGREEMENT OR THE LOAN  DOCUMENTS,  AND AGREE THAT NO SUCH PARTY
     WILL SEEK TO  CONSOLIDATE  ANY SUCH ACTION WITH ANY OTHER ACTION IN WHICH A
     JURY TRIAL CANNOT BE OR HAS NOT BEEN WAIVED  EXCEPT AS  PROHIBITED  BY LAW,
     BORROWERS  HEREBY  WAIVE ANY RIGHT THEY MAY HAVE TO CLAIM OR RECOVER IN ANY
     LITIGATION  ANY  SPECIAL,  EXEMPLARY,  PUNITIVE OR  CONSEQUENTIAL  DAMAGES.
     BORROWERS  CETIFY  THAT NO  REPRSENTATIVE,  AGENT OR  ATTORNEY  OF BANK HAS
     REPRESENTED,  EXPRESSLY OR  OTHERWISE  THAT BANK WOULD NOT, IN THE EVENT OF
     LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER. THIS WAIVER CONSTITUTES A
     MATERIAL  INDUCEMENT  FOR  BANK TO  ACCEPT  THE  LOAN  DOCUMENTS  AND  MAKE
     ADVANCES, THE TERM LOAN AND OTHER FINANCIAL  ACCOMODATIONS AVAILABLE TO THE
     BORROWERS.

                              [END OF SCHEDULE "A"]
                                  ------------THIRD SUBSTITUTE REVOLVING CREDIT NOTE

$12,500,000.00                                                September 30, 2002

     FOR  VALUE  RECEIVED,  the  undersigned,  BALTEK  CORPORATION,  a  Delaware
corporation and CRUSTACEA  CORPORATION,  a Delaware  corporation (each of Baltek
Corporation  and  Crustacea   Corporation  a  "Borrower"  and  collectively  the
"Borrowers"),  hereby jointly and severally unconditionally promise to pay on or
before December 31, 2003 (the "Maturity  Date"),  to the order of FLEET NATIONAL
BANK, a national banking association, as successor-by-merger to Summit Bank (the
"Bank"),  at the office of the Bank located at 208 Harristown  Road,  Glen Rock,
New Jersey,  or at such other  location as the Bank shall  designate,  in lawful
money of the United States of America and in immediately  available  funds,  the
principal amount of (i)  $12,500,000.00  or (ii) so much thereof (or any greater
amount,  if any) as shall have been advanced (the "Advances") by the Bank to the
Borrower  pursuant to that certain  Revolving Loan and Security  Agreement dated
December  21,  1999,  as  amended by a First  Amendment  to  Revolving  Loan and
Security  Agreement  dated as of  September  30,  2000,  a Second  Amendment  to
Revolving  Loan and  Security  Agreement  dated as of December 31, 2000, a Third
Amendment to Revolving Loan and Security Agreement and Modification to Equipment
Line of Credit  Note dated as of  September  28,  2001,  a Fourth  Amendment  to
Revolving Loan and Security  Agreement  dated as of July 31, 2002, but effective
as of June 30,  2002,  and a Fifth  Amendment  to  Revolving  Loan and  Security
Agreement and the Other Loan  Documents  dated  September  30, 2002,  all by and
among the  Borrowers  and the Bank,  as such Loan and Security  Agreement may be
further amended from time to time (collectively, the "Agreement"). Defined terms
used but not  expressly  defined  herein shall have the same  meanings when used
herein as set forth in the Agreement.

     The Borrowers  jointly and severally  further agree to pay interest in like
money at such office on the unpaid  principal amount hereof from time to time as
hereinafter  provided.  The unpaid  principal  amount hereof shall bear interest
commencing  with the date  hereof at a  fluctuating  rate per annum equal to the
Base Rate minus  three-quarters of one percent (3/4 of 1%). As used herein,  the
term "Base Rate" shall mean the rate of interest  announced from time to time by
the Bank as its "base  rate" or "base  lending  rate".  This rate of interest is
determined from time to time by the Bank as a means of pricing some loans to its
customers and is neither tied to any external rate of interest or index nor does
it necessarily  reflect the lowest rate of interest actually charged by the Bank
to any particular class or category of customers of the Bank.

     Interest  shall be calculated on the basis of a 360-day year for the actual
number of days elapsed and shall be adjusted  automatically as of the opening of
business  on each day on which any change in the Base Rate is  announced  by the
Bank at its principal office.

     Installments  of  accrued  interest  only shall be due and  payable  hereon
monthly,  with the first such installment being due and payable on the

<PAGE>

first day of the first month  following  the date hereof,  and the  remainder of
such monthly  installments of interest being due and payable on the first day of
each and every month  thereafter  until this Third  Substitute  Revolving Credit
Note shall have been paid in full.

     Notwithstanding  anything  contained herein to the contrary,  the Borrowers
shall have the option,  in  accordance  with  Section 2.1 of the  Agreement,  to
convert  all or any part of their  "Base Rate Loans" (as such term is defined in
the  Agreement)  to "LIBOR  Based  Rate  Loans"  (as such term is defined in the
Agreement),  and upon doing shall,  jointly and  severally,  pay interest on the
unpaid principal amount of this Third Substitute Revolving Credit Note from time
to time outstanding on a monthly basis.

     All advances  made by the Bank to the  Borrowers  hereunder may be noted by
the Bank on the Schedule annexed hereto, and the Bank is authorized to make such
notations  which  shall  be  prima  facie  evidence  of  the  principal   amount
outstanding  hereunder at any time; provided,  however, that any failure to make
such a notation (or any error in notation)  shall not limit or otherwise  affect
the obligation of the Borrowers hereunder which is and shall remain absolute and
unconditional.

     In the event that any  payment  due under this Third  Substitute  Revolving
Credit  Note shall not be received by Bank within ten (10) days of the due date,
the Borrowers  shall, to the extent  permitted by law, pay Bank a late charge of
five percent (5%) of the overdue  payment (but in no event more than  $2,500.00)
as  compensation to Bank. Any such late charge shall be in addition to all other
rights and remedies to which Bank may be entitled and shall be  immediately  due
and  payable.  Borrowers  acknowledge  that (i) such late  charge is a  material
inducement  to Bank to make the loan,  (ii) Bank would not have made the loan in
the absence of the agreement of the Borrowers to pay such late charge, and (iii)
such late charge in not a penalty and  represents a  reasonable  estimate of the
cost to Bank in allocating its resources  (both  personnel and financial) to the
additional review, monitoring, administration and collection of the loan.

     All payments received  hereunder may be applied first to the payment of any
expenses or charges payable hereunder and accrued interest, and the balance only
applied to principal.

     Subject to the  provisions  of  Section  2.7 of the  Agreement,  this Third
Substitute  Revolving  Credit Note may be prepaid,  in whole or in party, at one
time or from time to time, without prepayment premium or fee.

     This Third Substitute  Revolving Credit Note is a replacement of the Second
Substitute   Revolving  Credit  Note  dated  December  31,  2000,  which  was  a
replacement of the Substitute  Revolving  Credit Note dated  September 30, 2000,
which was a  replacement  of the Revolving  Credit Note dated  December 21, 1999
referred to in the Agreement and this Third Substitute  Revolving Credit Note is
the "Third Substitute  Revolving Credit Note" referred to in the Fifth Amendment
to Revolving  Loan and Security  Agreement  and the Other Loan  Documents  dated
September 30, 2002, and is secured by the Collateral  described in the Agreement
and the Guaranty Agreement.

                                       2
<PAGE>

     The Bank may  declare  this Third  Substitute  Revolving  Credit Note to be
immediately due and payable if an Event of Default shall have occurred under the
Agreement  or any of the other  Loan  Documents  (including  any  grace  periods
provided herein or therein).

     To the  extent  permitted  by law,  whenever  there is any Event of Default
under this Third  Substitute  Revolving Credit Note, the rate of interest on the
unpaid  principal  balance shall,  at the option of the Bank, be 5% in excess of
the rate of interest  provided  herein.  Borrowers  acknowledge  that:  (i) such
additional  rate is a material  inducement  to Bank to make the loan;  (ii) Bank
would not have made the loan in absence of the agreement of the Borrowers to pay
such additional  rate;  (iii) such additional rate represents  compensation  for
increased  risk to Bank that the loan will not be repaid;  and (iv) such rate is
not a penalty and  represents a  reasonable  estimate of (a) the cost to Bank in
allocating its resources (both personnel and financial) to the on-going  review,
monitoring,  administration  and collection of the loan and (b)  compensation to
Bank for losses that are difficult to ascertain.

     This Third Substitute  Revolving Credit Note may not be changed orally, but
only by an agreement in writing, signed by the party against whom enforcement of
any waiver, change, modification or discharge is sought.

     Should the  indebtedness  represented  by this Third  Substitute  Revolving
Credit  Note  or any  part  hereof  be  collected  at law  or in  equity,  or in
bankruptcy,  receivership,  or any other court proceeding,  or should this Third
Substitute  Revolving  Credit  Note be  placed  in the  hands of  attorneys  for
collection  upon  default,  the  Borrowers  agree  to pay,  in  addition  to the
principal  and  interest  due  and  payable  hereon,  all  reasonable  costs  of
collecting or attempting to collect this Third Substitute Revolving Credit Note,
including reasonable attorneys' fees and expenses and further including, without
limitation, all post judgment collection costs and expenses.

     This Third  Substitute  Revolving  Credit  Note shall be and remain in full
force and effect and in no way impaired until the actual payment  thereof to the
Bank, its successors or assigns.

     Anything  herein to the contrary  notwithstanding,  the  obligations of the
Borrowers under this Third Substitute  Revolving Credit Note shall be subject to
the  limitation  that  payments of interest  shall not be required to the extent
that receipt of any such payment by the Bank would be contrary to  provisions of
law  applicable to the Bank  limiting the maximum rate of interest  which may be
charged or collected by the Bank.

     Each of the  Borrowers  and all  endorsers  and  guarantors  of this  Third
Substitute  Revolving Credit Note hereby waive  presentment,  demand of payment,
protest and notice of dishonor of this Third Substitute Revolving Credit Note.

     This Third  Substitute  Revolving Credit Note is binding upon the Borrowers
and their  respective  successors  and assigns and shall inure to the benefit of
the Bank and its successors and assigns.

     This Third  Substitute  Revolving Credit Note and the rights and obligation
of the parties  hereto shall be subject to and governed by the laws of the State
of New Jersey.

                                       3

       IN WITNESS  WHEREOF,  the undersigned  have caused this Third  Substitute
Revolving  Credit  Note to be  duly  executed  by  their  respective  authorized
officers, all on the day and year above written.
