AMOUNT OF GUARANTY. The principal amount of this Guaranty is Two Hundred Forty
Six Thousand One Hundred and Twenty-eight & 00/100 Dollars ($246,128.00).

CONTINUING GUARANTY. For good and valuable consideration, Bradley Ross
("Guarantor") absolutely and unconditionally guarantees and promises to pay to
City National Bank ("Lender") or its order, in legal tender of the United States
of America, the Indebtedness (as that term is defined below) of Lenscard
Corporation, a Delaware Corporation ("Borrower") to Lender on the terms and
conditions set forth in this Guaranty. The obligations of Guarantor under this
Guaranty are continuing.

MAXIMUM LIABILITY. The maximum liability of Guarantor under this Guaranty shall
not exceed at any one time the sum of the principal amount of $246,128.00, plus
all interest thereon, plus all of Lender's costs, expenses, and attorneys fees
incurred in connection with or relating to (A) the collection of the indebted
ness, (B) the collection and sale of any collateral for the Indebtedness or this
Guaranty, or (C) the enforcement of this Guaranty. Attorney's fees include,
without limitation, attorneys' fees whether or not there is a lawsuit, and if
there is a lawsuit, any fees and costs for trial and appeals.

The above limitation on liability is not a restriction on the amount of the
indebtedness of Borrower to Lender either in the aggregate or at any one time.
If Lender presently holds one or more guaranties, or hereafter receives
additional guaranties from Guarantor, the rights of Lender under all guaranties
shall be cumulative. This Guaranty shall not (unless specifically provided below
to the contrary) affect or invalidate any such other guaranties. The liability

<PAGE>

of Guarantor will be the aggregate liability of Guarantor under the terms of
this Guaranty and any such other unterminated guaranties.

INDEBTEDNESS GUARANTEED. The indebtedness guaranteed by this Guaranty includes
any and all of Borrower's indebtedness to Lender and is used in the most
comprehensive sense and means and includes any and all of Borrower's
liabilities, obligations and debts to Lender, now existing or hereinafter
incurred or created, including, without limitation, all loans, advances,
interest, costs, debts, overdraft indebtedness, credit card indebtedness, lease
obligations, other obligations, and liabilities of Borrower, or any of them, and
any present or future judgments against Borrower, or any of them; and whether
any such indebtedness is voluntarily or involuntarily incurred, due or not due,
absolute or contingent, liquidated or unliquidated, determined or undetermined;
whether Borrower may be liable individually or jointly with others, or primarily
or secondarily, or as guarantor or surety; whether recovery on the indebtedness
may be or may become barred or unenforceable against Borrower for any reason
whatsoever; and whether the indebtedness arises from transactions which may be
voidable on account of infancy, insanity ultra vires or otherwise.

DURATION OF GUARANTY. This Guaranty will take effect when received by Lender
without the necessity of any acceptance by Lender, or any notice to Guarantor or
to Borrower, and will continue in full force until all Indebtedness incurred or
contracted before receipt by lender of any notice of revocation shall have been
fully and finally paid and satisfied and all of Guarantor's other obligations
under this Guaranty shall have been performed in full. If Guarantor elects to
revoke this Guaranty, Guarantor may only do so in writing. Guarantor's written
notice of revocation must be mailed to Lender, by certified mail, at Lender's
address listed above or such other place as Lender may designate in writing.
Written revocation of this Guaranty will apply only to advances or new
Indebtedness created after actual receipt by Lender of Guarantor's written
revocation. For this purpose and without limitation, the term "new Indebtedness"
does not include Indebtedness which at the time of notice of revocation is
contingent, unliquidated, undetermined or not due and which later becomes
absolute, liquidated, determined or due. This Guaranty will continue to bind
Guarantor for all Indebtedness incurred by Borrower or committed by Lender prior
to receipt of Guarantor's written notice of revocation, including any
extensions, renewals, substitutions or modifications of the Indebtedness. All
renewals, extensions, substitutions, and modifications of the Indebtedness
granted after Guarantor's revocation, are contemplated under this Guaranty and,
specifically will not be considered to be new Indebtedness. This Guaranty shall
bind Guarantor's estate as to Indebtedness created both before and after
Guarantor's death or incapacity, regardless of Lender's actual notice of
Guarantor's death. Subject to the foregoing, Guarantor's executor or
administrator or other legal representative may terminate this Guaranty in the
same manner in which Guarantor might have terminated it and with the same
effect. Release of any other guarantor or termination of any other guaranty of
the Indebtedness shall not affect the liability of Guarantor under this
Guaranty. A revocation Lender receives from any one or more Guarantors shall not
affect the liability of any remaining Guarantors under this Guaranty. It is
anticipated that fluctuations may occur in the aggregate amount of Indebtedness
covered by this Guaranty, and Guarantor specifically acknowledges and agrees
that reductions in the amount of Indebtedness, even to zero dollars ($0.00),

<PAGE>

prior to Guarantor's written revocation of this Guaranty shall not constitute a
termination of this Guaranty. This Guaranty is binding upon Guarantor and
Guarantor's heirs, successors and assigns so long as any of the guaranteed
Indebtedness remains unpaid and even though the Indebtedness guaranteed may from
time to time be zero dollars ($0.00).

OBLIGATIONS OF MARRIED PERSONS. Any married person who signs this Guaranty
hereby expressly agrees that recourse under this Guaranty may be had against
both his or her separate property and community property.

GUARANTORS AUTHORIZATION TO LENDER. Guarantor authorizes Lender, either before
or after any revocation hereof, without notice or demand and without lessening
Guarantor's liability under this Guaranty, from time to time: (A) prior to
revocation as set forth above, to make one or more additional secured or
unsecured loans to Borrower, to lease equipment or other goods to Borrower, or
otherwise to extend additional credit to Borrower; (B) to alter, compromise,
renew, extend, accelerate, or otherwise change one or more times the time of
payment or other terms of the Indebtedness or any part of the Indebtedness,
including increases and decreases of the rate of interest on the Indebtedness;
extensions may be repeated and may be for longer than the original loan term;
(C) to take and hold security for the payment of this Guaranty or the
Indebtedness, and exchange, enforce, waive, subordinate, fail or decide not to
perfect, and release any such security, with or without the substitution of new

or more of Borrower's sureties, endorsers, or other guarantors on any terms or
in any manner Lender may choose; (E) to determine how, when and what application

(G) to sell, transfer, assign, or grant participation in all or any part of the
Indebtedness; and (H) to assign or transfer this Guaranty in whole or in part.

Guarantor which would limit or qualify in any way the terms of this Guaranty;
(B) this Guaranty is executed at Borrower's request and not at the request of

written consent of Lender, sell, lease, assign, encumber, hypothecate, transfer,
or otherwise dispose of all or substantially all of Guarantor's assets, or any

financial and credit information in for acceptable to Lender, and all such

Guaranty, and Guarantor further agrees that, absent a request for information,
Lender shall have no obligation to disclose to Guarantor any information or
documents acquired by Lender in the course of its relationship with Borrower.

GUARANTOR'S WAIVERS. Except as prohibited by applicable law, Guarantor waives
any right to require Lender to (A) make any presentment, protest, demand, or
notice of any kind, including notice of change of any terms of repayment of the
Indebtedness, default by Borrower or any other guarantor or surety, any action
or nonaction taken by Borrower, Lender, or any other guarantor or surety of
Borrower, or the creation of new or additional Indebtedness; (B) proceed against
any person, including Borrower, before proceedings against Guarantor; (C)
proceed against any collateral for the Indebtedness, including Borrower's
collateral, before proceeding against Guarantor; (D) apply any payments or

terms, time, and place of any sale of the collateral pursuant to the Uniform
Commercial Code or any other law governing such sale; (F) disclose any
information about the Indebtedness, the Borrower, the collateral, or any other
guarantor or surety, or about any action or nonaction of Lender; or (G) pursue
any remedy or course of action in Lender's power whatsoever.

Guarantor also waives any and all rights or defenses arising by reason of (H)
any disability or other defense of Borrower, any other guarantor or surety or
any other person; (I) the cessation from any cause whatsoever, others than
payment in full, of the Indebtedness; (J) the application of proceeds of the
Indebtedness by Borrower for purposes other than the purposes understood and
intended by Guarantor and Lender; (K) any act or omission or commission by
lender which directly or indirectly results in or contributes to the discharge
of Borrower or any other guarantor or surety, or the Indebtedness, or the loss
or release of any collateral by operation of law or otherwise; (L) any statute
of limitations in any action under this Guaranty or on the Indebtedness; or (M)
any modification or change in terms of the Indebtedness, whatsoever, including

time and that payment of the Indebtedness is due and any change in the interest
rate, and including any such modification or change in terms after revocation of
this Guaranty on Indebtedness incurred prior to such revocation.

Guarantor waives all rights and any defenses arising out of an election of
remedies by Lender even though that the election of remedies, such as a
non-judicial foreclosure with respect to security for a guaranteed obligation,
has destroyed Guarantor's rights of subrogation and reimbursement against

<PAGE>

Borrower by operation of Section 580d of the California Code of Civil Procedure
or otherwise.

Guarantor waives all rights and defenses that Guarantor may have because
Borrower's obligation is secured by real property. This means among other
things: (1) Lender may collect from Guarantor without first foreclosing on any
real or personal property collateral pledged by Borrower. (2) If Lender
forecloses on any real property collateral pledged by Borrower: (a) the amount
of Borrower's obligation may be reduced only by the price for which the
collateral is sold at the foreclosure sale, even if the collateral is worth more
than the sale price. (b) Lender may collect from Guarantor even if Lender, by
foreclosing on the real property collateral, has destroyed any right Guarantor
may have to collect from borrower. This is an unconditional waiver of any rights
and defenses Guarantor may have because Borrower's obligation is secured by real
property. These rights and defenses include, but are not limited to, any rights
and defenses based upon Section 580a, 580b, 580d, or 726 of the Code of Civil
Procedure.

Guarantor understands and agrees that the foregoing waivers are waivers of
substantive rights and defenses to which Guarantor might otherwise be entitled
to under state and federal law. The rights and defenses waived include, without
limitation, those provided by California laws of suretyship and guaranty,
anti-deficiency laws, and the Uniform Commercial Code. Guarantor acknowledges
that guarantor has provided these waivers of rights and defenses with the
intention that they may be fully relied upon by Lender. Until all Indebtedness
is paid in full, Guarantor waives any right to enforce any remedy Lender may
have against the Borrower or any other guarantor, surety, or other person, and
further Guarantor waives any right to participate in any collateral for the
Indebtedness now or hereafter held by Lender.

GUARANTOR'S UNDERSTANDING WITH RESPECT TO WAIVERS. Guarantor warrants and agrees
that each of the waivers set froth above is made with Guarantor's full knowledge
of its significance and consequences and that, under the circumstances, the
waivers are reasonable and not contrary to public policy or law. If any such
waiver is determined to be contrary to any applicable law or public policy, such
wavier shall be effective only to the extent permitted by law or public policy.

SUBORDINATION OF BORROWER'S DEBTS TO GUARANTOR. Guarantor agrees that the
Indebtedness of Borrower to Lender, whether now existing or hereafter crated,
shall be superior to any claim that Guarantor may now have or hereafter acquire
against Borrower, whether or not Borrower becomes insolvent. Guarantor hereby
expressly subordinates any claim Guarantor may have against Borrower, upon any
account whatsoever, to any claim that Lender may now or hereafter have against
Borrower. In the event of insolvency and consequent liquidation of the assets of
Borrower, through bankruptcy, by an assignment for the benefit of creditors, by
voluntary liquidation, or otherwise, the assets of Borrower applicable to the
payment of the claims or both Lender and Guarantor shall be paid to Lender and
shall be first applied by Lender to the Indebtedness of Borrower to Lender.
Guarantor does hereby assign to Lender all claims which it may have or acquire
against Borrower or against any assignee or trustee in bankruptcy of Borrower;
provided however, that such assignment shall be effective only for the purpose

<PAGE>

of assuring to lender full payment in legal tender of the Indebtedness. If
Lender so requests, any notes or credit agreements now or hereafter evidencing
any debts or obligations of Borrower to Guarantor shall be marked with a legend
that the same are subject to this Guaranty and shall be delivered to Lender.
Guarantor agrees, and Lender hereby is authorized, in the name of Guarantor,
from time to time to execute and the financing statements and continuation
statements and to execute such other documents and to take such other actions as
Lender deems necessary or appropriate to perfect, preserve and enforce its
rights under this Guaranty.

         legal expenses whether or not there is a lawsuit, including attorneys'

         anticipated post-judgment collection services. Guarantor also shall pay
         all court costs and such additional fees as may be directed by the
         court.

         Caption Headings. Caption headings in this Guaranty are for convenience
         purposes only and are not to be used to interpret or define the
         provisions of this Guaranty.

         Governing Law. This Guaranty will be governed by, construed and
         enforced in accordance with federal law and the laws of the State of
         California. This Guaranty has been accepted by Lender in the State of
         California.

         Choice of Venue. IF there is a lawsuit, Guarantor agrees upon Lender's
         request to submit to the jurisdiction of the courts of LOS ANGELES
         county, State of California.

         Integration. Guarantor further agrees that Guarantor has read and fully
         understand the terms of this Guaranty; Guarantor has had the
         opportunity to be advised by Guarantor's attorney with respect to this
         Guaranty; the Guaranty fully reflects Guarantor's intentions and parol
         evidence is not required to interpret the terms of this Guaranty.

<PAGE>

         suffered or incurred by Lender as a result of any breach by Guarantor
         of the warranties, representations and agreements of this paragraph.

         Interpretation. In all cases where there is more than one Borrower or
         Guarantor, then all words used in this Guaranty in the singular shall
         be deemed to have been used in the plural where the context and
         construction so require: and where there is more than one Borrower
         named in this Guaranty or when this Guaranty is executed by more than
         one Guarantor, the words "Borrower" and "Guarantor" respectively shall
         mean all and any one or more of them. The words "Guarantor,"
         "Borrower," and "Lender" include the heirs, successors, assigns, and
         transferees of each of them. If a court finds that any provision of
         this Guaranty is not valid or should not be enforced, that fact by
         itself will not mean that the rest of this Guaranty will not be valid
         or enforced. Therefore, a court will enforce the rest of the provisions
         of this Guaranty even if a provision of this Guaranty may be found to
         be invalid or unenforceable. If any one or more of Borrower or
         Guarantor are corporations, partnerships, limited liability companies
         or similar entities, it is not necessary for Lender to inquire into the
         powers of Borrower or Guarantor or of the officers, directors,
         partners, managers or other agents acting or purporting to act on their
         behalf, and any Loan Indebtedness made or created in reliance upon the
         professed exercise of such powers shall be guaranteed under this
         Guaranty.

         Notices. Any notice required to be given under this Guaranty shall be
         given in writing, and, except for revocation notices by Guarantor,
         shall be effective when actually delivered, when actually received by
         telefacsimile (unless otherwise required by law), when deposited with a
         nationally recognized overnight courier, or, if mailed, when deposited
         in the United States mail, as first class, certified or registered mail
         postage prepaid, directed to the addresses shown near the beginning of
         this Guaranty. All revocation notices by Guarantor shall be in writing
         and shall be effective upon delivery to Lender as provided in the
         section of this Guaranty entitled "DURATION OF GUARANTY." Any party may
         change its address for notices under this Guaranty by giving formal
         written notice to the other parties, specifying that the purpose of the
         notice is to change the party's address. For notice purposes, Guarantor
         agrees to keep Lender informed at all times of Guarantor's current
         address. Unless otherwise provided or required by law, if these if more
         than one Guarantor, any notice given by Lender to any Guarantor is
         deemed to be notice given to all Guarantors.

         No Waiver by Lender. Lender shall not be deemed to have waived any
         rights under this Guaranty unless such waiver is given in writing and
         signed by Lender. No delay or omission on the part of Lender in
         exercising any right shall operate as a waiver of such right or any
         other right. A wavier by Lender of a provision of this Guaranty shall
         not prejudice or constitute a wavier of Lender's right otherwise to
         demand strict compliance with that provision or any other provision of
         this Guaranty. No prior waiver by Lender, nor any course of delaying
         between Lender and Guarantor, shall constitute a waiver of any of
         Lender's rights or of any of Guarantor's obligations as to any future

<PAGE>

         transactions. Whenever the consent of Lender is required under this
         Guaranty, the granting of such consent by Lender in any instance shall
         not constitute continuing consent to subsequent instances where such
         consent is required and in all cases such consent may be granted or
         withheld in the sole reasonable discretion of Lender.

         Successors and Assigns. Subject to any limitations stated in this
         Guaranty on transfer of Guarantor's interest, this Guaranty shall be
         binding upon and inure to the benefit of the parties, their successors
         and assigns.

Six Thousand One Hundred and Twenty-eight & 00/100 Dollars ($246,128.00).

CONTINUING GUARANTY. For good and valuable consideration, Dr. Luc Berthoud

City National Bank ("Lender") or its order, in legal tender of the United States
of America, the Indebtedness (as that term is defined below) of Lenscard

conditions set forth in this Guaranty. The obligations of Guarantor under this
Guaranty are continuing.

not exceed at any one time the sum of the principal amount of $246,128.00, plus
all interest thereon, plus all of Lender's costs, expenses, and attorneys fees
incurred in connection with or relating to (A) the collection of the indebted
ness, (B) the collection and sale of any collateral for the Indebtedness or this
Guaranty, or (C) the enforcement of this Guaranty. Attorney's fees include,
without limitation, attorneys' fees whether or not there is a lawsuit, and if

The above limitation on liability is not a restriction on the amount of the
indebtedness of Borrower to Lender either in the aggregate or at any one time.
If Lender presently holds one or more guaranties, or hereafter receives
additional guaranties from Guarantor, the rights of Lender under all guaranties
shall be cumulative. This Guaranty shall not (unless specifically provided below
to the contrary) affect or invalidate any such other guaranties. The liability
of Guarantor will be the aggregate liability of Guarantor under the terms of
this Guaranty and any such other unterminated guaranties.

<PAGE>

INDEBTEDNESS GUARANTEED. The indebtedness guaranteed by this Guaranty includes
any and all of Borrower's indebtedness to Lender and is used in the most
comprehensive sense and means and includes any and all of Borrower's
liabilities, obligations and debts to Lender, now existing or hereinafter
incurred or created, including, without limitation, all loans, advances,
interest, costs, debts, overdraft indebtedness, credit card indebtedness, lease
obligations, other obligations, and liabilities of Borrower, or any of them, and
any present or future judgments against Borrower, or any of them; and whether
any such indebtedness is voluntarily or involuntarily incurred, due or not due,
absolute or contingent, liquidated or unliquidated, determined or undetermined;
whether Borrower may be liable individually or jointly with others, or primarily
or secondarily, or as guarantor or surety; whether recovery on the indebtedness
may be or may become barred or unenforceable against Borrower for any reason
whatsoever; and whether the indebtedness arises from transactions which may be
voidable on account of infancy, insanity ultra vires or otherwise.

DURATION OF GUARANTY. This Guaranty will take effect when received by Lender
without the necessity of any acceptance by Lender, or any notice to Guarantor or
to Borrower, and will continue in full force until all Indebtedness incurred or
contracted before receipt by lender of any notice of revocation shall have been
fully and finally paid and satisfied and all of Guarantor's other obligations
under this Guaranty shall have been performed in full. If Guarantor elects to
revoke this Guaranty, Guarantor may only do so in writing. Guarantor's written
notice of revocation must be mailed to Lender, by certified mail, at Lender's
address listed above or such other place as Lender may designate in writing.
Written revocation of this Guaranty will apply only to advances or new
Indebtedness created after actual receipt by Lender of Guarantor's written
revocation. For this purpose and without limitation, the term "new Indebtedness"
does not include Indebtedness which at the time of notice of revocation is
contingent, unliquidated, undetermined or not due and which later becomes
absolute, liquidated, determined or due. This Guaranty will continue to bind
Guarantor for all Indebtedness incurred by Borrower or committed by Lender prior
to receipt of Guarantor's written notice of revocation, including any
extensions, renewals, substitutions or modifications of the Indebtedness. All
renewals, extensions, substitutions, and modifications of the Indebtedness
granted after Guarantor's revocation, are contemplated under this Guaranty and,
specifically will not be considered to be new Indebtedness. This Guaranty shall
bind Guarantor's estate as to Indebtedness created both before and after
Guarantor's death or incapacity, regardless of Lender's actual notice of
Guarantor's death. Subject to the foregoing, Guarantor's executor or
administrator or other legal representative may terminate this Guaranty in the
same manner in which Guarantor might have terminated it and with the same
effect. Release of any other guarantor or termination of any other guaranty of
the Indebtedness shall not affect the liability of Guarantor under this
Guaranty. A revocation Lender receives from any one or more Guarantors shall not
affect the liability of any remaining Guarantors under this Guaranty. It is
anticipated that fluctuations may occur in the aggregate amount of Indebtedness
covered by this Guaranty, and Guarantor specifically acknowledges and agrees
that reductions in the amount of Indebtedness, even to zero dollars ($0.00),
prior to Guarantor's written revocation of this Guaranty shall not constitute a
termination of this Guaranty. This Guaranty is binding upon Guarantor and
Guarantor's heirs, successors and assigns so long as any of the guaranteed
Indebtedness remains unpaid and even though the Indebtedness guaranteed may from
time to time be zero dollars ($0.00).

<PAGE>

GUARANTOR'S WAIVERS. Except as prohibited by applicable law, Guarantor waives
any right to require Lender to (A) make any presentment, protest, demand, or
notice of any kind, including notice of change of any terms of repayment of the
Indebtedness, default by Borrower or any other guarantor or surety, any action
or nonaction taken by Borrower, Lender, or any other guarantor or surety of
Borrower, or the creation of new or additional Indebtedness; (B) proceed against
any person, including Borrower, before proceedings against Guarantor; (C)
proceed against any collateral for the Indebtedness, including Borrower's
collateral, before proceeding against Guarantor; (D) apply any payments or
proceeds received against the Indebtedness in any order; (E) give notice of the
terms, time, and place of any sale of the collateral pursuant to the Uniform
Commercial Code or any other law governing such sale; (F) disclose any
information about the Indebtedness, the Borrower, the collateral, or any other
guarantor or surety, or about any action or nonaction of Lender; or (G) pursue
any remedy or course of action in Lender's power whatsoever.

Guarantor also waives any and all rights or defenses arising by reason of (H)
any disability or other defense of Borrower, any other guarantor or surety or
any other person; (I) the cessation from any cause whatsoever, others than
payment in full, of the Indebtedness; (J) the application of proceeds of the
Indebtedness by Borrower for purposes other than the purposes understood and
intended by Guarantor and Lender; (K) any act or omission or commission by
lender which directly or indirectly results in or contributes to the discharge
of Borrower or any other guarantor or surety, or the Indebtedness, or the loss
or release of any collateral by operation of law or otherwise; (L) any statute
of limitations in any action under this Guaranty or on the Indebtedness; or (M)
any modification or change in terms of the Indebtedness, whatsoever, including

time and that payment of the Indebtedness is due and any change in the interest
rate, and including any such modification or change in terms after revocation of
this Guaranty on Indebtedness incurred prior to such revocation.

Guarantor waives all rights and any defenses arising out of an election of
remedies by Lender even though that the election of remedies, such as a
non-judicial foreclosure with respect to security for a guaranteed obligation,
has destroyed Guarantor's rights of subrogation and reimbursement against
Borrower by operation of Section 580d of the California Code of Civil Procedure
or otherwise.

<PAGE>

Guarantor waives all rights and defenses that Guarantor may have because
Borrower's obligation is secured by real property. This means among other
things: (1) Lender may collect from Guarantor without first foreclosing on any
real or personal property collateral pledged by Borrower. (2) If Lender
forecloses on any real property collateral pledged by Borrower: (a) the amount
of Borrower's obligation may be reduced only by the price for which the
collateral is sold at the foreclosure sale, even if the collateral is worth more
than the sale price. (b) Lender may collect from Guarantor even if Lender, by
foreclosing on the real property collateral, has destroyed any right Guarantor
may have to collect from borrower. This is an unconditional waiver of any rights
and defenses Guarantor may have because Borrower's obligation is secured by real
property. These rights and defenses include, but are not limited to, any rights
and defenses based upon Section 580a, 580b, 580d, or 726 of the Code of Civil
Procedure.

Guarantor understands and agrees that the foregoing waivers are waivers of
substantive rights and defenses to which Guarantor might otherwise be entitled
to under state and federal law. The rights and defenses waived include, without
limitation, those provided by California laws of suretyship and guaranty,
anti-deficiency laws, and the Uniform Commercial Code. Guarantor acknowledges
that guarantor has provided these waivers of rights and defenses with the
intention that they may be fully relied upon by Lender. Until all Indebtedness
is paid in full, Guarantor waives any right to enforce any remedy Lender may
have against the Borrower or any other guarantor, surety, or other person, and
further Guarantor waives any right to participate in any collateral for the
Indebtedness now or hereafter held by Lender.

GUARANTOR'S UNDERSTANDING WITH RESPECT TO WAIVERS. Guarantor warrants and agrees
that each of the waivers set froth above is made with Guarantor's full knowledge
of its significance and consequences and that, under the circumstances, the
waivers are reasonable and not contrary to public policy or law. If any such
waiver is determined to be contrary to any applicable law or public policy, such
wavier shall be effective only to the extent permitted by law or public policy.

SUBORDINATION OF BORROWER'S DEBTS TO GUARANTOR. Guarantor agrees that the
Indebtedness of Borrower to Lender, whether now existing or hereafter crated,
shall be superior to any claim that Guarantor may now have or hereafter acquire
against Borrower, whether or not Borrower becomes insolvent. Guarantor hereby
expressly subordinates any claim Guarantor may have against Borrower, upon any
account whatsoever, to any claim that Lender may now or hereafter have against
Borrower. In the event of insolvency and consequent liquidation of the assets of
Borrower, through bankruptcy, by an assignment for the benefit of creditors, by
voluntary liquidation, or otherwise, the assets of Borrower applicable to the
payment of the claims or both Lender and Guarantor shall be paid to Lender and
shall be first applied by Lender to the Indebtedness of Borrower to Lender.
Guarantor does hereby assign to Lender all claims which it may have or acquire
against Borrower or against any assignee or trustee in bankruptcy of Borrower;
provided however, that such assignment shall be effective only for the purpose
of assuring to lender full payment in legal tender of the Indebtedness. If
Lender so requests, any notes or credit agreements now or hereafter evidencing
any debts or obligations of Borrower to Guarantor shall be marked with a legend
that the same are subject to this Guaranty and shall be delivered to Lender.
Guarantor agrees, and Lender hereby is authorized, in the name of Guarantor,
from time to time to execute and the financing statements and continuation
statements and to execute such other documents and to take such other actions as
Lender deems necessary or appropriate to perfect, preserve and enforce its
rights under this Guaranty.

         provisions of this Guaranty.

         Governing Law. This Guaranty will be governed by, construed and
         enforced in accordance with federal law and the laws of the State of

         of the warranties, representations and agreements of this paragraph.

<PAGE>

         Interpretation. In all cases where there is more than one Borrower or
         Guarantor, then all words used in this Guaranty in the singular shall
         be deemed to have been used in the plural where the context and
         construction so require: and where there is more than one Borrower
         named in this Guaranty or when this Guaranty is executed by more than
         one Guarantor, the words "Borrower" and "Guarantor" respectively shall
         mean all and any one or more of them. The words "Guarantor,"
         "Borrower," and "Lender" include the heirs, successors, assigns, and
         transferees of each of them. If a court finds that any provision of
         this Guaranty is not valid or should not be enforced, that fact by
         itself will not mean that the rest of this Guaranty will not be valid
         or enforced. Therefore, a court will enforce the rest of the provisions
         of this Guaranty even if a provision of this Guaranty may be found to
         be invalid or unenforceable. If any one or more of Borrower or
         Guarantor are corporations, partnerships, limited liability companies
         or similar entities, it is not necessary for Lender to inquire into the
         powers of Borrower or Guarantor or of the officers, directors,
         partners, managers or other agents acting or purporting to act on their
         behalf, and any Loan Indebtedness made or created in reliance upon the
         professed exercise of such powers shall be guaranteed under this
         Guaranty.

         Notices. Any notice required to be given under this Guaranty shall be
         given in writing, and, except for revocation notices by Guarantor,
         shall be effective when actually delivered, when actually received by
         telefacsimile (unless otherwise required by law), when deposited with a
         nationally recognized overnight courier, or, if mailed, when deposited
         in the United States mail, as first class, certified or registered mail
         postage prepaid, directed to the addresses shown near the beginning of
         this Guaranty. All revocation notices by Guarantor shall be in writing
         and shall be effective upon delivery to Lender as provided in the
         section of this Guaranty entitled "DURATION OF GUARANTY." Any party may
         change its address for notices under this Guaranty by giving formal
         written notice to the other parties, specifying that the purpose of the
         notice is to change the party's address. For notice purposes, Guarantor
         agrees to keep Lender informed at all times of Guarantor's current
         address. Unless otherwise provided or required by law, if these if more
         than one Guarantor, any notice given by Lender to any Guarantor is
         deemed to be notice given to all Guarantors.

         No Waiver by Lender. Lender shall not be deemed to have waived any
         rights under this Guaranty unless such waiver is given in writing and
         signed by Lender. No delay or omission on the part of Lender in
         exercising any right shall operate as a waiver of such right or any
         other right. A wavier by Lender of a provision of this Guaranty shall
         not prejudice or constitute a wavier of Lender's right otherwise to
         demand strict compliance with that provision or any other provision of
         this Guaranty. No prior waiver by Lender, nor any course of delaying
         between Lender and Guarantor, shall constitute a waiver of any of
         Lender's rights or of any of Guarantor's obligations as to any future
         transactions. Whenever the consent of Lender is required under this
         Guaranty, the granting of such consent by Lender in any instance shall
         not constitute continuing consent to subsequent instances where such
         consent is required and in all cases such consent may be granted or
         withheld in the sole reasonable discretion of Lender.

<PAGE>

         Successors and Assigns. Subject to any limitations stated in this
         Guaranty on transfer of Guarantor's interest, this Guaranty shall be
         binding upon and inure to the benefit of the parties, their successors
         and assigns.
