      2. ISSUANCE OF VOTING SHARES TO THE VOTING TRUSTEE. The Voting Trustee
shall cause all Share Certificates deposited with it pursuant to Section 1 above
to be surrendered to and cancelled by the Company, and shall cause the Company
to issue and deliver to the Voting Trustee new share certificates representing
the Shares in the name of the Voting Trustee, as voting trustee, which shall
contain a legend stating that the Share Certificates are issued pursuant and
subject to the provisions of this Agreement. The Company's stock ledger and
journal shall indicate that such share certificates are subject to the
provisions of this Agreement. Except as herein provided, all share certificates
issued and delivered to the Voting Trustee pursuant to this Section 2 shall at
all times be and remain in the possession of the Voting Trustee or a depository
designated by the Voting Trustee. The Voting Trustee shall not transfer any
certificates representing Shares other than as provided in this Agreement.

      3. RECORDS OF VOTING TRUST CERTIFICATES.

            (a) Records. The Voting Trustee shall keep or cause to be kept books
of record of all Voting Trust Certificates issued pursuant to this Agreement,
and shall also fix and determine a place at which such books of record shall be
kept and at which Voting Trust Certificates may be transferred.

            (b) Inspection of Records of Voting Trust Certificates. Any owner of
a Voting Trust Certificate shall have the right to inspect the books of record
of the Voting Trust Certificates to be maintained by the Voting Trustee pursuant
to subsection (a) of this Section at the place at which such records are kept at
any reasonable time.

      4. TRANSFER OF VOTING TRUST CERTIFICATES.

            (a) Transfer of Voting Trust Certificates. All transfers of Voting
Trust Certificates shall be recorded on the books of record kept by the Voting
Trustee. The Voting Trustee may treat the record holder of the respective Voting
Trust Certificates as the absolute owner thereof for all purposes whatsoever and
shall not be bound to recognize any equitable interest in or claim to any such
Voting Trust Certificate or the Shares represented thereby on the part of any
other party until transferred on such books of record. The Voting Trustee shall
not be required to make any transfer of a Voting Trust Certificate upon such
books of record except upon surrender of a Voting Trust Certificate to be
transferred, properly assigned in such form as shall be acceptable to the Voting
Trustee, accompanied by such evidence as the Voting Trustee may reasonably
require as to the authority of any person other than the record holder thereof
who may seek to effect any such transfer and as to the genuineness of the
appropriate signatures. Upon each such transfer, the Voting Trust Certificates
surrendered for transfer shall be cancelled and the Voting Trustee shall issue a
new Voting Trust Certificate to the transferee and the transferee shall, by
acceptance thereof, assent to the terms and conditions of this Agreement. Any
such transferee shall be required to execute a supplemental copy of this
Agreement.

            (b) Replacement of Voting Trust Certificates. In the event any
Voting Trust Certificate shall become mutilated, lost, or destroyed, the Voting
Trustee, under such conditions with respect to indemnity or otherwise as it, in
its discretion, may prescribe, may provide for the

issuance of a new Voting Trust Certificate in lieu of such lost or destroyed
Voting Trust Certificate or in exchange for such mutilated Voting Trust
Certificate.

      5. POWERS AND DUTIES OF VOTING TRUSTEE.

            (a) Right to Vote. The Voting Trustee shall be entitled to exercise
all shareholder rights of the Shareholders in respect of the Shares, including,
but not limited to, the right to exercise the voting rights of such Shares on
each matter submitted to the Company's shareholders for their vote, consent,
waiver, release, or other action and the right to take part in any corporate or
shareholders' action of the Company, whether ordinary or extraordinary, by proxy
or otherwise. The right of the Voting Trustee to exercise the voting rights of
the Shares in accordance with the terms hereof includes, but is not limited to,
the exercise of voting rights relating to fixing the number and the election of
directors of the Company, the changing of the Company's capital structure, the
amendment of the Company's Articles of Incorporation or Code of Regulations, the
reclassification of the Shares, the purchase of assets by the Company, and the
merger, consolidation, liquidation or dissolution of the Company. The owners of
Voting Trust Certificates shall not have any right under such Voting Trust
Certificates or under this Agreement or otherwise, to exercise the voting rights
of such Shares or to take part in any corporate or shareholders' action or to do
or perform any act or thing that shareholders of the Company are now or may
hereafter become entitled to do or to perform, for so long as the Shares owned
by each such Shareholder are held by the Voting Trustee, except to receive cash
dividends and distributions when declared and paid and to review the books and
records of the Company during normal business hours. Notwithstanding anything to
the contrary, the Voting Trustee shall not have the right to sell or otherwise
transfer the Shares of any Shareholder.

            (b) Discretion of Voting Trustee. In exercising the voting rights of
the Shares, or in doing any act with respect to the control or management of the
Company or its affairs, or otherwise acting hereunder, the Voting Trustee shall
be free to exercise its full discretion. Notwithstanding anything to the
contrary, the Voting Trustee shall not have the right to sell or otherwise
transfer the Shares of any Shareholder.

            (c) Acting as Director or Officer. The Voting Trustee, or any
representative of the Voting Trustee, may act as a director, an officer or an
employee of the Company and may vote for itself as such and may have an
ownership interest in the Company. The Voting Trustee, or any person with whom
or which it may be associated, or any entity of which it may be a member, or any
corporation of which it may be a shareholder, director, or officer, may contract
with the Company or otherwise have a financial interest in any matter or
transaction to which the Company may be a party or in which the Company may be
in any way concerned, as though it were not Voting Trustee, but otherwise
subject to law.

            (d) Compensation. The Voting Trustee shall serve without
compensation. The Voting Trustee shall be reimbursed for all reasonable
expenses, disbursements and advances incurred or made by the Voting Trustee in
performance of its duties hereunder. The owners of the Voting Trust Certificates
agree to reimburse and indemnify the Voting Trustee for all reasonable claims,
expenses, and liabilities incurred by it in connection with the discharge of its
duties under this Agreement. Any such claims, expenses, or liabilities shall be
charged to the

                                       3
<PAGE>

Voting Trust Certificate owners, pro rata, and may be deducted from dividends or
other distributions to them, or may be made a charge payable as a condition to
the delivery of Share Certificates following the surrender to the Voting Trustee
of the Voting Trust Certificates, and the Voting Trustee shall be entitled to a
lien therefor on the Shares, funds, or other property in its possession. The
Voting Trustee shall disclose in reasonable detail on an annual basis, all
reimbursements received for reasonable expenses, disbursements, advances
incurred or made by the Voting Trustee in performance of its duties hereunder.

            (e) Immunities of the Voting Trustee. The Voting Trustee shall incur
no responsibility in its capacity as voting trustee, as a shareholder, or
otherwise, by reason of any error of judgment or mistake of law or other
mistake, for any act or omission of any agent or attorney, for any
misconstruction of this Agreement, or for any action of any sort taken or
omitted hereunder or believed by it to be in accordance with the provisions and
intent hereof or otherwise, except solely for its own individual willful
misconduct. In the discharge of its duties hereunder, the Voting Trustee shall
be fully protected in acting in reliance upon any instrument, document, or paper
believed by it to be genuine and to have been executed by the proper parties;
and, shall likewise be fully protected in issuing any Voting Trust Certificate
or in taking or refraining from taking any action hereunder in reliance upon any
certificate or certificates purporting to be duly signed, as to the existence or
non-existence of any fact or facts or the performance or non-performance of any
act or acts, and may accept as conclusive any statement made in any such
certificate. The Voting Trustee shall not be required to give bond or security
for the discharge of its duties under this Agreement. The Voting Trustee, may in
its discretion, consult with counsel to be selected by it and shall incur no
liability in respect of any action taken on the advice of any such counsel.

            (f) Dividends. The record owner of each Voting Trust Certificate
shall be entitled to receive his pro rata share of any dividends paid or
distributed by the Company upon the Shares represented by the Voting Trust
Certificates and all other corporate distributions made by the Company in
respect of such Voting Shares; provided, however, that, if any such dividend or
distribution includes shares of capital stock of the Company with voting rights,
the certificates representing such shares of stock shall be deposited with the
Voting Trustee subject to the terms of this Agreement, and the owner of the
Voting Trust Certificate evidencing the Shares upon which such dividend or
distribution is made shall be entitled to receive new Voting Trust Certificates
representing such newly-deposited shares of capital stock with voting rights.

            The record date fixed by the Company for the purpose of the payment
of any dividend or for the making of any other distribution shall be the record
date for the purpose of payment or distribution to the owners of Voting Trust
Certificates, and whenever any such record date shall be fixed, the owners of
record of Voting Trust Certificates at the date so fixed shall exclusively be
entitled to participate in the payment or distribution. Upon receipt by the
Voting Trustee of any dividend or other distribution in respect of any Shares
held by the Voting Trustee, the Voting Trustee shall promptly distribute the
funds or property so received by it to the owners of Voting Trust Certificates
to whom such funds or property should have been distributed by the Company if
the foregoing provisions hereof had been observed.

                                       4

            Notwithstanding the foregoing provisions of this Section 5, if the
Company shall reclassify its Shares, reorganize, sell all or substantially all
of its assets with or without dissolution, consolidate with or merge into
another corporation, or if another corporation shall merge into the Company, the
shares of capital stock into which the Shares then on deposit hereunder shall be
reclassified and any shares of capital stock issued in exchange or substitution
for the Shares then on deposit hereunder shall, if they are non-voting shares,
be distributed in accordance with the provisions of this Agreement directly to
the record owners of outstanding Voting Trust Certificates, issued in respect of
such Shares; or, if they are voting shares, they shall become subject to the
terms and conditions of this Agreement as if such voting shares had been
originally deposited hereunder, and shall be deposited with the Voting Trustee,
and the owner of outstanding Voting Trust Certificates shall be entitled to
receive new Voting Trust Certificates representing such newly deposited shares
of capital stock with voting rights.

            (g) Deductions for Distributions. There shall be deducted and
withheld from every distribution of every kind under this Agreement any taxes,
assessments, or other charges that may be required by law to be deducted or
withheld, as well as expenses and charges incurred pursuant to Section 5(d), to
the extent that the expenses and charges remain unpaid or unreimbursed.
