AMENDED AND RESTATED TERM NOTE

$5,400,000.00

August 12, 2010

FOR VALUE RECEIVED, the undersigned, UNILENS CORP. USA, a Delaware corporation
and UNILENS VISION SCIENCES INC., a Delaware corporation (jointly and severally,
“Maker”), promise to pay to the order of REGIONS BANK, an Alabama banking
corporation (“Lender”), in lawful money of the United States of America, in
immediately available funds, at the principal office of Lender at 100 North
Tampa Street, Suite 3100, Tampa, Florida 33602, or at such other location as the
Lender may designate from time to time, the principal sum of Five Million Four
Hundred Thousand and No/100 Dollars ($5,400,000.00) or so much thereof which may
be advanced by Lender in accordance with the terms of the Credit and Security
Agreement dated as of November 9, 2009, as modified by that certain Joinder
Agreement and First Amendment to Credit and Security Agreement dated as of the
date hereof between Lender and Maker (as amended, “Loan Agreement”), together
with interest thereon, as described below. Capitalized terms used herein and not
otherwise defined shall have the meaning assigned to them in the Loan Agreement.

This Note shall bear interest on the daily outstanding balance of principal at a
variable rate per annum, calculated on a 365/360 basis, equal to (i) the LIBOR
Rate plus three and one quarter percent (3.25%) if the Funded Debt to EBITDA
ratio is less than 1:00 to 1:00, or (ii) the LIBOR Rate plus three and three
quarters percent (3.75%) if the Funded Debt to EBITDA ratio is equal to or
greater than 1:00 to 1:00, such LIBOR Rate to change automatically from time to
time, but not more often than once per month. Notwithstanding the foregoing, in
no event shall the interest rate thereunder be less than four and three quarters
percent (4.75%) per annum; provided, however, such foregoing minimum rate shall
not be applicable during any time that Swap Documents (as hereinafter defined)
are in effect. Any necessary change to the interest rate spread shall occur
within thirty (30) days after Lender’s receipt of Maker’s required financial
reporting requirements.

The principal and interest under this Note shall be payable as follows:

(i) a principal payment in the amount of One Hundred Thousand and No/100 Dollars
($100,000.00) plus all accrued and unpaid interest shall be due and payable
beginning on August 19, 2010 and continuing on the nineteenth (19th ) of each
calendar month thereafter (each a “Payment Date”); and

(ii) The entire outstanding unpaid principal balance of this Note, together with
accrued and unpaid interest and any other amounts due under this Note, the Loan
Agreement and the other Loan Documents shall be due and payable on January 19,
2015 (“Maturity Date”).

Interest on the indebtedness evidenced by this Note shall accrue and be
calculated on a 365/360 basis; that is by applying the ratio of the interest
rate over a year of 360 days, multiplied by the outstanding principal balance,
multiplied by the actual number of days the principal balance is outstanding.

--------------------------------------------------------------------------------

For purposes of this Note, the following terms shall have the following
meanings:

“Interest Period” means, with respect to the initial Interest Period hereunder,
the period commencing on the date funds are advanced on the Original Note (as
hereinafter defined) and, with respect to any subsequent Interest Period
hereunder, the period commencing on the last day of the immediately preceding
Interest Period, and in any case ending on the day numerically corresponding to
the date funds are advanced on this Note in the first month thereafter; provided
that any Interest Period which begins on a day of a calendar month for which
there is no numerically corresponding day in the appropriate subsequent calendar
month shall end on the last day of the appropriate subsequent calendar month.

“LIBOR Business Day” shall mean a day on which the office of Lender at which
payments on the Loan are to be made is open for business and on which dealings
in U.S. dollar deposits are carried out in the London Interbank market.

“LIBOR Rate” shall mean, with respect to any Interest Period, the rate for
deposits in U.S. dollars for a period comparable to the terms of such Interest
Period which appears on Reuters Screen LIBOR01 Page as of 11:00 a.m., London,
England time on the day (the “Pricing Date”) that is two LIBOR Business Days
preceding the first day of such Interest Period, as such rate is published on
the Business Day next following the Pricing Date in the Money Market Section of
The Wall Street Journal. If such rate cannot be so determined for any reason,
Lender will request the principal London office of at least two banks to provide
a quotation of its rate for deposits in U.S. dollars for a period comparable to
the applicable quotations.

This Note is the Term Note referred to in, and issued pursuant to, the Loan
Agreement, the terms of which are incorporated herein by reference. The Loan
Agreement contains provisions for, among other things, the acceleration of the
stated maturity of this Note upon the happening of certain stated events set
forth therein.

Maker does hereby authorize and instruct Lender to debit and draft maker’s
checking account maintained with Lender bearing account number 0123277386
(and/or any other accounts maintained with Lender) for all payments and amounts
due to Lender monthly hereunder, as the monthly payments hereunder may vary from
month to month.

The principal amount of this Note may be prepaid in whole or in part at any time
without penalty. Early payments will not, unless agreed to by Lender in writing,
relieve Maker of Maker’s obligation to make payments under the payment schedule.

In the event this Note is not paid in full on the Maturity Date, the amount due
hereunder shall bear interest at a rate per annum equal to the interest rate
calculated pursuant to the second paragraph hereof, plus an additional plus two
percent (2.00%), such interest rate to change automatically from time to time,
payable on demand. The aforesaid interest rate shall continue to apply whether
or not judgment shall be entered on this Note.

If any payment of principal or interest on this Note shall become due on a
Saturday, Sunday or on any other day on which Lender’s offices in Birmingham,
Alabama or such other office designated by Lender, are not open for business,
such payment shall be made on the preceding Business Day.

--------------------------------------------------------------------------------

If any payment is 15 or more days late, Maker will be charged a late fee equal
to five percent (5.00%) of the unpaid portion of such payment.

In no contingency or event whatsoever shall the interest rate charged hereunder
exceed the highest rate permissible under applicable state and federal law. In
the event Lender has received interest hereunder in excess of the highest
allowed rate, Lender shall promptly refund such excess to Maker.

All payments received by Lender hereunder shall be applied first to unpaid
interest, second to the principal balance hereof and third to other charges
payable by Maker.

The Term Loan made by Lender to Maker pursuant to the Loan Agreement and all
payments and prepayments on account of the principal and interest thereof shall
be recorded by Lender on the Term Loan Account which account statements, absent
manifest error, shall be conclusive and binding on Maker; provided, however,
that the failure of Lender to make any such recordation shall not limit or
otherwise affect the obligation of Maker hereunder.

If Maker fails to pay any portion of the amounts due hereunder when due and
payable or if Maker fails to perform, keep or observe any other term, provision,
condition, covenant, warranty or representation contained herein, in the Loan
Agreement, in the Revolving Credit Note, in the Swap Documents or in any of the
Other Agreements, it shall be an Event of Default hereunder.

Maker hereby waives presentment, demand, protest and notice of any kind in
connection with this Note.

This Note shall bind Maker and its successors and assigns, and the benefits
hereof shall inure to the benefit of Lender and its successors and assigns. All
references herein to the “Maker” and “Lender” shall be deemed to apply to Maker
and Lender, respectively, and their respective successors and assigns.

Maker covenants and agrees that it will maintain in full force and effect that
certain ISDA Master Agreement between Maker and Lender, or its affiliate, and
all swap documents, and related agreements, together with any related schedules
and confirmations entered into now or in the future (being collectively referred
to as the “Swap Documents”), and promptly pay and perform all of its obligations
under the Swap Documents. The payment of the Note, and the payment and
performance of Maker’s obligations under the Swap Documents are hereby secured
by the Loan Agreement and other related security instruments and all Swap
Documents are deemed to be part of the Loan Documents. A default under any of
the Swap Documents shall be a default under the Note, the Loan Agreement, and
all security instruments related thereto. Notwithstanding any language contained
in such documents, Maker shall not prepay the Note, or any indebtedness without
simultaneously paying all sums due under the Swap Documents attributable or
arising from such prepayment.

To the extent permitted by applicable law, Maker hereby grants to Lender and
Lender reserves a right of setoff in all Maker’s accounts with Lender (whether
checking, savings, or some other account). This includes all accounts Maker
holds jointly with someone else and all accounts Maker may open in the future.
However, this does not include any IRA or Keogh accounts, or any trust accounts
for which setoff would be prohibited by law. Maker authorizes

--------------------------------------------------------------------------------

Lender, to the extent permitted by applicable law, to charge or setoff all sums
owing on the Indebtedness against any and all such accounts, and, at Lender’s
option, to administratively freeze all such accounts to allow Lender to protect
Lender’s charge and setoff rights provided in this paragraph.

Maker hereby consents and agrees, without notice from Lender, to any extension
of payment or waiver thereof with respect to this Note.

This Note, for all purposes, shall be governed by, and construed in accordance
with, the laws of the State of Florida. In the event any provision of this Note
shall be prohibited or invalid under applicable law, such provision shall be
ineffective to the extent of such prohibition or invalidity without invalidating
the remainder of such provision or the remaining provisions of this Note.

The obligations of each person and entity comprising Maker shall be joint and
several. The unenforceability or invalidly of any provision of this Note as to
any entity or circumstance shall not render that provision unenforceable or
invalid as to any other entity or circumstance and all provisions hereof, in all
other respects shall remain valid and enforceable.

WAIVER OF JURY TRIAL. NO PARTY TO THIS NOTE OR ANY ASSIGNEE, SUCCESSOR, HEIR OR
PERSONAL REPRESENTATIVE OF A PARTY SHALL SEEK A JURY TRIAL IN ANY LAW SUIT,
PROCEEDING, COUNTERCLAIM, OR ANY OTHER LITIGATION PROCEDURE BASED UPON OR
ARISING OUT OF THIS NOTE, ANY RELATED AGREEMENT OR INSTRUMENT, ANY SECURITY FOR
THE INDEBTEDNESS EVIDENCED HEREBY OR THE DEALINGS OR THE RELATIONSHIP BETWEEN OR
AMONG THE PARTIES, OR ANY OF THEM. NO PARTY WILL SEEK TO CONSOLIDATE ANY SUCH
ACTION, IN WHICH A JURY TRIAL HAS BEEN WAIVED, WITH ANY OTHER ACTION IN WHICH A
JURY TRIAL CANNOT OR HAS NOT BEEN WAIVED. THE PROVISIONS OF THIS PARAGRAPH HAVE
BEEN FULLY DISCUSSED BY THE PARTIES HERETO, AND THESE PROVISIONS SHALL BE
SUBJECT TO NO EXCEPTIONS. NO PARTY HAS IN ANY WAY AGREED WITH OR REPRESENTED TO
ANY OTHER PARTY THAT THE PROVISIONS OF THIS PARAGRAPH WILL NOT BE FULLY ENFORCED
IN ALL INSTANCES.

Maker hereby agrees that this is a renewal of that certain Term Note dated
November 9, 2009 (“Original Note”) from Unilens Corp. USA to Lender
(“Obligation”) and not a refinance of said Obligation. Maker further
acknowledges and agrees that the Obligation has remained and shall continue
without interruption or derogation of the security interest granted in
connection therewith.

“Maker”), promises to pay to the order of REGIONS BANK, an Alabama banking
corporation (“Lender”), in lawful money of the United States of America, in
immediately available funds, at the principal office of Lender at 100 North
Tampa Street, Suite 3100, Tampa, Florida 33602, or at such other location as
Lender may designate from time to time, the principal sum of One Million Five
Hundred Thousand and No/100 Dollars ($1,500,000.00) or so much thereof which may
have been advanced pursuant to the Credit and Security Agreement dated as of
November 9, 2009, as modified pursuant to that certain Joinder Agreement and
First Amendment to Credit and Security Agreement dated of even date herewith
between Lender and Maker (as amended, “Loan Agreement”), together with interest
thereon, as described below. Capitalized terms used herein and not otherwise
defined shall have the meaning assigned to them in the Loan Agreement.

This Note shall bear interest on the daily outstanding balance of principal at a
variable rate per annum, calculated on a 365/360 basis, equal to (i) the LIBOR
Rate plus three and one quarter percent (3.25%) if the Funded Debt to EBITDA
ratio is less than 1:00 to 1:00, or (ii) the LIBOR Rate plus three and three
quarters percent (3.75%) if the Funded Debt to EBITDA ratio is equal to or
greater than 1:00 to 1:00, such LIBOR Rate to change automatically from time to
time, but not more often than once per month. Notwithstanding the foregoing, in
no event shall the interest rate hereunder be less than four and three quarters
percent (4.75%) per annum. Any necessary change to the interest rate spread
shall occur within thirty (30) days after Lender’s receipt of Maker’s required
financial reporting requirements.

The principal and interest under this Note shall be payable as follows:

(i) an interest payment of all accrued unpaid interest on the outstanding
principal balance of the Loan shall be due and payable beginning on September 9,
2010 and continuing on the ninth (9th) day of each calendar month thereafter

(ii) the entire outstanding unpaid principal balance of this Note, together with
accrued and unpaid interest and any other amounts due under this Note, the Loan
Agreement and the other Loan Documents shall be due and payable on November 8,
2010, subject to extension as more particularly described below (“Maturity

Interest on the indebtedness evidenced by this Note shall accrue and be
calculated on a 365/360 basis; that is by applying the ratio of the interest
rate over a year of 360 days, multiplied by the outstanding principal balance,
multiplied by the actual number of days the principal balance is outstanding.

This is a revolving credit note and the principal may be paid down and
reborrowed during the term of this Note.

--------------------------------------------------------------------------------

In Lender’s sole discretion, the Maturity Date may be extended for a term of 364
days. No more than two such extensions of the Maturity Date will be made. If
Lender elects to allow the Maturity Date to be extended, no further action or
documentation will be required of Lender or Borrower. If Lender elects to not
allow the Maturity Date to be extended, Lender will mail a written notice of
Lender’s election to Borrower’s address as reflected on Lender’s records for the
Revolving Loan. Any such extension of the Maturity Date will be on the same
terms, conditions and provisions of this Agreement and the Revolving Credit Note
(except for the Maturity Date, which will be extended by 364 days), including,
without limitation, Borrower’s obligation to make payments of principal and/or
interest and this Note shall continue in full force and effect. Lender will have
no obligation to extend the Maturity Date, and no extension of the Maturity Date
will further obligate Lender to grant any subsequent, further or additional
extensions of the Maturity Date.

For purposes of this Note, the following terms shall have the following
meanings:

“Interest Period” means, with respect to the initial Interest Period hereunder,
the period commencing on the date of the Original Note (as hereinafter defined)
and, with respect to any subsequent Interest Period hereunder, the period
commencing on the last day of the immediately preceding Interest Period, and in
any case ending on the day numerically corresponding to the date of this Note in
the first month thereafter; provided that any Interest Period which begins on a
day of a calendar month for which there is no numerically corresponding day in
the appropriate subsequent calendar month shall end on the last day of the
appropriate subsequent calendar month.

“LIBOR Business Day” shall mean a day on which the office of Lender at which
payments on the Loan are to be made is open for business and on which dealings
in U.S. dollar deposits are carried out in the London Interbank market.

“LIBOR Rate” shall mean, with respect to any Interest Period, the rate for
deposits in U.S. dollars for a period comparable to the terms of such Interest
Period which appears on Reuters Screen LIBOR01 Page as of 11:00 a.m., London,
England time on the day (the “Pricing Date”) that is two LIBOR Business Days
preceding the first day of such Interest Period, as such rate is published on
the Business Day next following the Pricing Date in the Money Market Section of
The Wall Street Journal. If such rate cannot be so determined for any reason,
Lender will request the principal London office of at least two banks to provide
a quotation of its rate for deposits in U.S. dollars for a period comparable to
the applicable Interest Period and the rate for such Interest Period will be the
arithmetic mean of such quotations.

“Minimum Rate” shall mean four and three quarters percent (4.75%) per annum.

This Note is the Revolving Credit Note referred to in, and issued pursuant to,
the Loan Agreement, the terms of which are incorporated herein by reference. The
Loan Agreement contains provisions for, among other things, the acceleration of
the stated maturity of this Note upon the happening of certain stated events set
forth therein.

--------------------------------------------------------------------------------

Maker does hereby authorize and instruct Lender to debit and draft maker’s
checking account maintained with Lender bearing account number 0123277386
(and/or any other accounts maintained with Lender) for all payments and amounts
due to Lender monthly hereunder, as the monthly payments hereunder may vary from
month to month.

The principal amount of this Note may be prepaid in whole or in part at any time
without penalty. Early payments will not, unless agreed to by Lender in writing,
relieve Maker of Maker’s obligation to make payments under the payment schedule.

In the event this Note is not paid in full on the Maturity Date, the amount due
hereunder shall bear interest at a rate per annum equal to the interest rate
calculated pursuant to the second paragraph hereof, plus an additional two
percent (2.00%), such interest rate to change automatically from time to time,
payable on demand. The aforesaid interest rate shall continue to apply whether
or not judgment shall be entered on this Note.

If any payment of principal or interest on this Note shall become due on a
Saturday, Sunday or on any other day on which Lender’s offices in Birmingham,
Alabama or such other office designation by Lender, are not open for business,
such payment shall be made on the preceding Business Day.

If any payment is 15 or more days late, Maker will be charged a late fee equal
to five percent (5.00%) of the unpaid portion of such payment.

In no contingency or event whatsoever shall the interest rate charged hereunder
exceed the highest rate permissible under applicable state and federal law. In
the event Lender has received interest hereunder in excess of the highest
allowed rate, Lender shall promptly refund such excess to Maker.

All payments received by Lender hereunder shall be applied first to unpaid
interest, second to the principal balance hereof and third to other charges
payable by Maker.

All advances under the Revolving Credit Loan made by Lender to Maker pursuant to
the Loan Agreement and all payments and prepayments on account of the principal
and interest thereof shall be recorded by Lender on the Revolving Credit Loan
Account which account statements, absent manifest error, shall be conclusive and
binding on Maker; provided, however, that the failure of Lender to make any such
recordation shall not limit or otherwise affect the obligation of Maker
hereunder.

If Maker fails to pay any portion of the amounts due hereunder when due and
payable or if Maker fails to perform, keep or observe any other term, provision,
condition, covenant, warranty or representation contained herein, in the Loan
Agreement, in the Term Note, in the Swap Documents or in any of the Other
Agreements, it shall be an Event of Default hereunder.

Maker hereby waives presentment, demand, protest and notice of any kind in
connection with this Note.

This Note shall bind Maker and its successors and assigns, and the benefits
hereof shall inure to the benefit of Lender and its successors and assigns. All
references herein to the “Maker” and “Lender” shall be deemed to apply to Maker
and Lender, respectively, and their respective successors and assigns.

--------------------------------------------------------------------------------

Provided that Maker draws funds under the Term Loan, Maker covenants and agrees
that it will maintain in full force and effect that certain ISDA Master
Agreement between Maker and Lender, or its affiliate, and all swap documents,
and related agreements, together with any related schedules and confirmations
entered into now or in the future (being collectively referred to as the “Swap
Documents”), and promptly pay and perform all of its obligations under the Swap
Documents. The payment of the Note, and the payment and performance of Maker’s
obligations under the Swap Documents are hereby secured by the Loan Agreement
and other related security instruments and all Swap Documents are deemed to be
part of the Loan Documents. A default under any of the Swap Documents shall be a
default under the Note, the Loan Agreement, and all security instruments related
thereto. Notwithstanding any language contained in such documents, Maker shall
not prepay the Note, or any indebtedness without simultaneously paying all sums
due under the Swap Documents attributable or arising from such prepayment.

To the extent permitted by applicable law, Maker hereby grants to Lender and
Lender reserves a right of setoff in all Maker’s accounts with Lender (whether
checking, savings, or some other account). This includes all accounts Maker
holds jointly with someone else and all accounts Maker may open in the future.
However, this does not include any IRA or Keogh accounts, or any trust accounts
for which setoff would be prohibited by law. Maker authorizes Lender, to the
extent permitted by applicable law, to charge or setoff all sums owing on the
Indebtedness against any and all such accounts, and, at Lender’s option, to
administratively freeze all such accounts to allow Lender to protect Lender’s
charge and setoff rights provided in this paragraph.

Maker hereby consents and agrees, without notice from Lender, to any extension
of payment or waiver thereof with respect to this Note.

This Note, for all purposes, shall be governed by, and construed in accordance
with, the laws of the State of Florida. In the event any provision of this Note
shall be prohibited or invalid under applicable law, such provision shall be
ineffective to the extent of such prohibition or invalidity without invalidating
the remainder of such provision or the remaining provisions of this Note.

The obligations of each person and entity comprising Maker shall be joint and
several. The unenforceability or invalidly of any provision of this Note as to
any entity or circumstance shall not render that provision unenforceable or
invalid as to any other entity or circumstance and all provisions hereof, in all
other respects shall remain valid and enforceable.

WAIVER OF JURY TRIAL. NO PARTY TO THIS NOTE OR ANY ASSIGNEE, SUCCESSOR, HEIR OR
PERSONAL REPRESENTATIVE OF A PARTY SHALL SEEK A JURY TRIAL IN ANY LAW SUIT,
PROCEEDING, COUNTERCLAIM, OR ANY OTHER LITIGATION PROCEDURE BASED UPON OR
ARISING OUT OF THIS NOTE, ANY RELATED AGREEMENT OR INSTRUMENT, ANY SECURITY FOR
THE INDEBTEDNESS EVIDENCED HEREBY OR THE DEALINGS OR THE RELATIONSHIP BETWEEN OR
AMONG THE PARTIES, OR ANY OF THEM. NO PARTY WILL SEEK TO

--------------------------------------------------------------------------------

CONSOLIDATE ANY SUCH ACTION, IN WHICH A JURY TRIAL HAS BEEN WAIVED, WITH ANY
OTHER ACTION IN WHICH A JURY TRIAL CANNOT OR HAS NOT BEEN WAIVED. THE PROVISIONS
OF THIS PARAGRAPH HAVE BEEN FULLY DISCUSSED BY THE PARTIES HERETO, AND THESE
PROVISIONS SHALL BE SUBJECT TO NO EXCEPTIONS. NO PARTY HAS IN ANY WAY AGREED
WITH OR REPRESENTED TO ANY OTHER PARTY THAT THE PROVISIONS OF THIS PARAGRAPH
WILL NOT BE FULLY ENFORCED IN ALL INSTANCES.

Maker hereby agrees that this is a renewal of that certain Revolving Credit Note
dated November 9, 2009 (“Original Note”) from Unilens Corp. USA to Lender
(“Obligation”) and not a refinance of said Obligation. Maker further
acknowledges and agrees that the Obligation has remained and shall continue
without interruption or derogation of the security interest granted in
connection therewith.

IN WITNESS WHEREOF, Maker has executed this Note on the date first above
written.
