accrued and unpaid interest to that date was $19,873.84.

     B.   Payment of the Revolving Note is secured by, without limitation, all

     C.   Payment of the Revolving Note is also secured by, without limitation,
a Deed of Trust dated August 30, 1995, and filed for record with the Douglas
County Register of Deeds on August 31, 1995, as Document No. 13536, encumbering
certain real property as more specifically described therein, as the same may

     D.   Payment of the Revolving Note is also secured by, without limitation,
an Assignment of Leases and Rent dated August 30, 1995, and filed for record

     E.   Payment of the Revolving Note is guaranteed by Design and
Manufacturing, Inc., Xenotech Strong, Inc., Strong Westrex, Inc., and Xenotech
Rental Corp. by their corporate guaranties dated December 1, 1998 (collectively

accounts, inventory, equipment, and general intangibles as more specifically
described in their security agreements dated August 30, 1995 and December 1,
1998.

     F.   The Borrower and Guarantors executed a Loan Repayment Agreement dated
December 29, 2000; an Extension Agreement dated January 31, 2001; a Second
Extension Agreement dated March 15, 2001; and a Third Extension Agreement dated
April 27, 2001, which set forth additional terms and conditions with regard to
the above described indebtedness (collectively "the Agreement"). Terms not
otherwise defined in this Fourth Extension shall have the same meanings ascribed
to them in the Agreement.

     G.   The Revolving Note again matures June 30, 2001, and the Borrower and
Guarantors have requested that the Bank extend the Revolving Note in order for
the Borrower to conclude its efforts to refinance the loan, which the Bank has
agreed to do pursuant to the terms and conditions of this Fourth Extension.

     NOW, THEREFORE, in consideration of the foregoing and for good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged, the
parties agree as follows:

     1.   ACKNOWLEDGMENT. The Borrower and the Guarantors acknowledge and agree
that the recitals herein are true and correct and that the indebtedness under
the Revolving Note is due and owing to the Bank without offset, defense or
counterclaims and further acknowledge that the Security Agreement, Deed of
Trust, Assignment and other documents evidencing the security for the Revolving
Note are valid, binding and fully enforceable according to their terms; and
further acknowledge that the Guaranties and security agreements therefor are
valid and binding and fully enforceable according to their terms.

     2.   EXTENSION OF REVOLVING NOTE. Subject to the other terms and conditions
of this Fourth Extension, and subject to all terms and conditions of the
Agreement, as amended herein, the indebtedness evidenced by the Revolving Note

     10.  MISCELLANEOUS.

          10.1 The provisions of this Fourth Extension shall be in addition to
     those of any guaranties, deeds of trust, assignments, pledges, security
     agreements, note or other evidence of liability held by the Bank and
     executed by the Borrower or the Guarantors, all of which shall be construed
     as complementary to each other. Nothing herein contained shall prevent the
     Bank from enforcing any or all other guaranties, deeds of trust,
     assignments, pledges, security agreements, note or other evidence of
     liability in accordance with their respective terms.

          10.2 The Bank shall have the right at all times to enforce the
     provisions of this Fourth Extension and the collateral documents in strict
     accordance with the terms hereof and thereof, notwithstanding any conduct
     or custom on the part of the Bank in refraining from so doing at any time
     or times. The failure of the Bank at any time or times to enforce its
     rights under such provisions, strictly in accordance with the same, shall
     not be construed as having created a custom, conduct or course of dealing
     in any way or manner contrary to specific provisions of this Fourth
     Extension or as having in any way or manner modified or waived the same.
     All rights and remedies of the Bank are cumulative and concurrent and the
     exercise of one right or remedy shall not be deemed a waiver or release of
     any other right or remedy.

          10.3 This Fourth Extension shall inure to the benefit of, and shall be
     binding upon, the respective successors and permitted assigns of the
     parties hereto. The Borrower and the Guarantors have no right to assign any
     of its rights or obligations hereunder without the prior written consent of
     the Bank. This Fourth Extension, and the documents referred to herein or
     executed and delivered pursuant hereto, constitute the entire agreement
     between the parties, and may be amended only by a writing signed on behalf
     of each party. There are no promises, inducements or terms and conditions
     other than as specifically set forth herein.

          10.4 If any provision of this Fourth Extension shall be held invalid
     under any applicable laws, such invalidity shall not affect any other
     provision of this Fourth Extension that can be given effect without the
     invalid provision, and, to this end, the provisions hereof are severable.

          10.5 No failure of the Bank, or of the holder of the Revolving Note,
     in exercising any right, power or privilege hereunder shall affect such
     right, power or privilege, nor shall any single or partial exercise thereof
     preclude any further

                                      -5-

<Page>

     exercise thereof or the exercise of any other right, power or privilege.
     The rights and remedies of the Bank or the holder of the Revolving Note or
     other evidence of liability under this Fourth Extension are cumulative and
     not exclusive of any rights and remedies which it may otherwise have.

          10.6 This Fourth Extension may be executed in any number of
     counterparts, each of which shall be deemed to be an original, but all of
     which together shall constitute but one and the same instrument.

          10.7 If any provision contained in this Fourth Extension is
     inconsistent with any provision of any of the documents described herein or
     any other document in favor of the Bank, the provision contained in this
     Fourth Extension shall supersede such inconsistent provision in the
     document described herein or any document in favor of the Bank.

          10.8 The substantive laws of the State of Nebraska shall govern the
     construction of this Fourth Extension and the rights and remedies of the
     parties hereto.

     11.  FEES AND EXPENSES. Upon execution of this Fourth Extension, the
Borrower shall pay to the Bank an extension fee of $10,000.00, which shall be
deemed fully earned and not applied to the outstanding indebtedness under the
Revolving Note. In addition the Borrower agrees, within 10 days of invoice, to
pay to the Bank all expenses including, but not limited to, (i) the reasonable
fees and expenses of legal counsel for the Bank, incurred in connection with the
preparation, administration, amendment, modification or enforcement of this
Fourth Extension and the collateral documents and the collection or attempted
collection of the indebtedness; and (ii) expenses of future collateral audits
conducted by the Bank at the Bank's customary rates.

     12.  ADVICE OF COUNSEL. The Borrower and the Guarantors acknowledge that
they have reviewed this Fourth Extension in its entirety, having consulted such
legal, tax or other advisors as they deem appropriate and understand and agree
to each of the provisions of this Fourth Extension and further acknowledge that
they have entered into this Fourth Extension voluntarily.

         9. MISCELLANEOUS.

                  9.1 The provisions of this Fifth Extension shall be in
         addition to those of any guaranties, deeds of trust, assignments,
         pledges, security agreements, note or other evidence of liability held
         by the Bank and executed by the Borrower or the Guarantors, all of
         which shall be construed as complementary to each other. Nothing herein
         contained shall prevent the Bank from enforcing any or all other
         guaranties, deeds of trust, assignments, pledges, security agreements,
         note or other evidence of liability in accordance with their respective
         terms.

                  9.2 The Bank shall have the right at all times to enforce the
         provisions of this Fifth Extension and the collateral documents in
         strict accordance with the terms hereof and thereof, notwithstanding
         any conduct or custom on the part of the Bank in refraining from so
         doing at any time or times. The failure of the Bank at any time or
         times to enforce its rights under such provisions, strictly in
         accordance with the same, shall not be construed as having created a
         custom, conduct or course of dealing in any way or manner contrary to
         specific provisions of this Fifth Extension or as having in any way or
         manner modified or waived the same. All rights and remedies of the Bank
         are cumulative and concurrent and the exercise of one right or remedy
         shall not be deemed a waiver or release of any other right or remedy.

                  9.3 This Fifth Extension shall inure to the benefit of, and
         shall be binding upon, the respective successors and permitted assigns
         of the parties hereto. The Borrower and the Guarantors have no right to
         assign any of its rights or obligations hereunder without the prior
         written consent of the Bank. This Fifth Extension, and the documents
         referred to herein or executed and delivered pursuant hereto,
         constitute the entire agreement between the parties, and may be amended
         only by a writing signed on behalf of each party. There are no
         promises, inducements or terms and conditions other than as
         specifically set forth herein.

                  9.4 If any provision of this Fifth Extension shall be held
         invalid under any applicable laws, such invalidity shall not affect any
         other provision of this Fifth Extension that can be given effect
         without the invalid provision, and, to this end, the provisions hereof
         are severable.

                  9.5 No failure of the Bank, or of the holder of the Revolving
         Note, in exercising any right, power or privilege hereunder shall
         affect such right, power or privilege, nor shall any single or partial
         exercise thereof preclude any further exercise thereof or the exercise
         of any other right, power or privilege. The rights and remedies of the
         Bank or the holder of the Revolving Note or other evidence of liability
         under this Fifth Extension are cumulative and not exclusive of any
         rights and remedies which it may otherwise have.

                  9.6 This Fifth Extension may be executed in any number of
         counterparts, each of which shall be deemed to be an original, but all
         of which together shall constitute but one and the same instrument.

                  9.7 If any provision contained in this Fifth Extension is
         inconsistent with any provision of any of the documents described
         herein or any other document in favor of the Bank, the provision
         contained in this Fifth Extension

                                      -5-

<Page>

         shall supersede such inconsistent provision in the document described
         herein or any document in favor of the Bank.

                  9.8 The substantive laws of the State of Nebraska shall govern
         the construction of this Fifth Extension and the rights and remedies of
         the parties hereto.

         10. FEES AND EXPENSES. Upon execution of this Fifth Extension, the
Borrower shall pay to the Bank an extension fee of $0.00, which shall be deemed
fully earned and not applied to the outstanding indebtedness under the Revolving
Note. In addition the Borrower agrees, within 10 days of invoice, to pay to the
Bank all expenses including, but not limited to, (i) the reasonable fees and
expenses of legal counsel for the Bank, incurred in connection with the
preparation, administration, amendment, modification or enforcement of this
Fifth Extension and the collateral documents and the collection or attempted
collection of the indebtedness; and (ii) expenses of future collateral audits
conducted by the Bank at the Bank's customary rates.

         11. ADVICE OF COUNSEL. The Borrower and the Guarantors acknowledge that
they have reviewed this Fifth Extension in its entirety, having consulted such
legal, tax or other advisors as they deem appropriate and understand and agree
to each of the provisions of this Fifth Extension and further acknowledge that

Extension as of the day and year first above written.
