Exhibit 10.18    
    


CONTINUING GUARANTY  


        For
value received and in consideration of the extension of credit by BANK OF THE WEST (the "Bank") to INTERNATIONAL MEDICATION SYSTEMS,
LIMITED (the "Debtor") or the benefits to the undersigned derived therefrom, the undersigned (each, a
"Guarantor"), guarantees and promises to pay to the Bank any and all Indebtedness (as defined in Subsection 1 below) and agrees as follows: 


	1.
	Indebtedness. The term "Indebtedness" is used herein in its most comprehensive sense and
includes any and all advances, debts, obligations, guaranties and liabilities of the Debtor, or anyone or more of them, heretofore, now, or hereafter made, incurred or created, whether voluntary or
involuntary and however arising, whether direct or acquired by the Bank by assignment, succession, or otherwise, whether due or not due, absolute or contingent, liquidated or unliquidated, determined
or undetermined, secured or unsecured, whether on original, renewed, extended or revised terms, and whether the Debtor may be liable individually or jointly with others, or whether recovery upon any
Indebtedness may be or hereafter becomes barred by any statute of limitations or whether any Indebtedness may be or hereafter becomes otherwise unenforceable.



	2.
	Guaranty. The Guarantor unconditionally agrees to pay to the Bank or its order, on demand, in lawful money of the United States of
America, an amount equal to the amount of the Indebtedness and to otherwise perform any obligation of the Debtor undertaken pursuant to any Indebtedness. The Guarantor agrees to (a) bear the
expenses enumerated in Subsection 21 hereof and (b) pay interest on the Indebtedness at the rate(s) applicable thereto.



	3.
	Right to Amend or Modify Indebtedness and/or Collateral. The Guarantor authorizes the Bank, at its sole discretion, with or without
notice and without affecting the Guarantor's liability hereunder, from time to time to: (a) change the time or manner of payment of any Indebtedness by renewal, extension, modification,
acceleration or otherwise; (b) alter or change any provision of any Indebtedness including, but not limited to, the rate of interest thereon, and any document, instrument or agreement (other
than this Guaranty) evidencing, guaranteeing, securing or related to any Indebtedness; (c) release, discharge, exonerate, substitute or add one or more parties liable on any Indebtedness or one
or more endorsers, cosigners or guarantors for any Indebtedness; (d) obtain collateral for the payment of any Indebtedness or any guaranty thereof; (e) release existing or after-acquired
collateral on such terms as the Bank, in its sole discretion, shall determine; (f) apply any sums received from the Debtor, any endorser, cosigner, other guarantor or other person liable on any
Indebtedness or from the sale or collection of collateral or its proceeds to any indebtedness whatsoever owed or to be owed to the Bank by the Debtor in any order or amount and regardless of whether
or not such indebtedness is guaranteed hereby, is secured by collateral or is due and payable; (g) apply any sums received from the Guarantor or from the sale of collateral granted by the
Guarantor to any Indebtedness in any order or amount regardless of whether such Indebtedness is secured by collateral or is due and payable.



	4.
	Waivers. The Guarantor hereby unconditionally and irrevocably acknowledges and agrees to the matters set forth below:



	(a)
	Deficiency. In the event that any Indebtedness is now or hereafter secured by a deed of trust, the Guarantor waives any defense and all
rights and benefits of those laws purporting to state that no deficiency judgment may be recovered on certain real property purchase money obligations (as presently contained in Section 580b of
the California Code of Civil Procedure and as it may be amended or superseded in the future) and those laws purporting to state that no deficiency judgment may be recovered after a trustee's sale
under a deed of trust (as presently contained in Section 580d of the California Code of Civil Procedure and as it may 





1







 


be
amended or superseded in the future). THE GUARANTOR ACKNOWLEDGES THAT A FORECLOSURE BY A TRUSTEE'S SALE UNDER A DEED OF TRUST MAY RESULT IN THE DESTRUCTION OF THE GUARANTOR'S SUBROGATION RIGHTS
THAT MAY OTHERWISE EXIST AND THAT A DESTRUCTION OF THOSE RIGHTS MAY CREATE A DEFENSE TO A DEFICIENCY JUDGMENT AGAINST THE DEBTOR AND/OR THE GUARANTOR. 






THE
GUARANTOR WAIVES ALL RIGHTS AND DEFENSES THAT GUARANTOR MAY HAVE BECAUSE THE INDEBTEDNESS OR ANY PORTION THEREOF IS SECURED BY REAL PROPERTY. THIS MEANS, AMONG OTHER THINGS, 


	(1)
	BANK
MAY COLLECT FROM THE GUARANTOR WITHOUT FIRST FORECLOSING ON ANY REAL OR PERSONAL PROPERTY PLEDGED BY THE DEBTOR



	(2)
	IF
THE BANK FORECLOSES ON ANY REAL PROPERTY COLLATERAL PLEDGED BY THE DEBTOR,



	A.
	THE
AMOUNT OF THE INDEBTEDNESS MAY BE REDUCED ONLY BY THE PRICE FOR WHICH THAT COLLATERAL IS SOLD AT THE FORECLOSURE SALE, EVEN IF THE COLLATERAL IS WORTH MORE THAN THE SALE PRICE.



	B.
	BANK
MAY COLLECT FROM THE GUARANTOR EVEN IF THE CREDITOR, BY FORECLOSING ON THE REAL PROPERTY COLLATERAL, HAS DESTROYED ANY RIGHT THE GUARANTOR MAY HAVE TO COLLECT FROM THE DEBTOR. 







THIS
IS AN UNCONDITIONAL AND IRREVOCABLE WAIVER OF ANY RIGHTS AND DEFENSES THE GUARANTOR MAY HAVE BECAUSE THE INDEBTEDNESS IS SECURED BY REAL PROPERTY. THESE RIGHTS AND DEFENSES INCLUDE, BUT ARE NOT
LIMITED TO, ANY RIGHTS AND DEFENSES BASED ON SECTION 580a, 580b, 5800, OR 726 OF THE CALIFORNIA CODE OF CIVIL PROCEDURE. 



	(b)
	Election of Remedies. The Guarantor waives any defense based upon the Guarantor's loss of a right against the Debtor arising from the
Bank's election of a remedy on any Indebtedness under bankruptcy or other debtor relief laws or under any other laws, including, but not limited to, those purporting to reduce the Bank's right against
the Guarantor in proportion to the principal obligation of any Indebtedness (as presently contained in Section 2809 of the California Civil Code and as it may be amended or superseded in the
future). 





Without
limiting the generality of the foregoing, Guarantor waives all rights and defenses arising out of an election of remedies by the Bank, even though that election of remedies, such as a
nonjudicial foreclosure with respect to security for a guaranteed obligation, has destroyed the Guarantor's rights of subrogation and reimbursement against the Debtor (principal) by operation of
Section 580d of the Code of Civil Procedure or otherwise. 



	(c)
	Statute of Limitations. To the maximum extent permitted by law, the Guarantor waives the benefit of the statute of limitations
affecting the Guarantor's liability hereunder or the enforcement hereof.



	(d)
	Action Against the Debtor and Collateral (and Other Remedies). The Guarantor waives all right to require the Bank to:
(i) proceed against the Debtor, any endorser, cosigner, other guarantor or other person liable on any Indebtedness; (ii) join the Debtor or any endorser, cosigner, other guarantor or
other person liable on any Indebtedness in any action or actions that may be brought and prosecuted by the Bank solely and separately against the Guarantor 



2







 


on
any Indebtedness; (iii) proceed against any item or items of collateral securing any Indebtedness or any guaranty thereof; or (iv) pursue or refrain from pursuing any other remedy
whatsoever in the Bank's power. 



	(e)
	Debtor's Defenses. The Guarantor waives any defense arising by reason of any disability or other defense of the Debtor, the Debtor's
successor or any endorser, cosigner, other guarantor or other person liable on any Indebtedness including, without limitation, any statute of limitation defense that may be available to Debtor or such
other person. Until all Indebtedness has been paid in full, even though it may be in excess of the liability incurred hereby and Bank has no further commitment to lend or extend financial
accommodations to Debtor, the Guarantor shall not have any right of subrogation and the Guarantor waives any benefit of and right to participate in any collateral now or hereafter held by the Bank.
The Guarantor waives all presentments, demands for performance, notices of nonperformance, protests, notices of protest, notices of dishonor, notices of sale of any collateral securing any
Indebtedness or any guaranty thereof, and notice of the existence, creation or incurring of new or additional Indebtedness.



	(f)
	Debtor's Financial Condition. The Guarantor hereby recognizes, acknowledges and agrees that advances may be made from time to time with
respect to any Indebtedness without authorization from or notice to the Guarantor even though the financial condition of the Debtor, any endorser, cosigner, other guarantor or other person liable on
any Indebtedness may have deteriorated since the date of this Guaranty. The Guarantor waives all right to require the Bank to disclose any information with respect to: any Indebtedness; the financial
condition, credit or character of the Debtor, any endorser, cosigner, other guarantor or other person liable on any Indebtedness; any collateral securing any Indebtedness or any guaranty thereof; or
any action or inaction on the part of the Bank, the Debtor or any endorser, cosigner, other guarantor or other person liable on any Indebtedness. The Guarantor hereby assumes the responsibility for
being informed of the financial condition, credit and character of the Debtor and of all circumstances bearing upon the risk of non-payment of any Indebtedness which diligent inquiry would
reveal.






	5.
	Right of Set-off; Grant of Security Interest. In addition to all liens upon and rights of set-off against any
monies, securities or other property of the Guarantor given to the Bank by law, the Bank shall have a security interest in and a right to set off against all monies, securities and other property of
the Guarantor now or hereafter in the possession of or on deposit with the Bank, the Bank's agents or anyone or more of them, whether held in general or special account or deposit or for safekeeping
or otherwise; and each such security interest and right of set-off may be exercised without demand upon or notice to the Guarantor. No action or inaction by the Bank with respect to any
security interest or right of set-off shall be deemed a waiver thereof and every right of set-off and security interest shall continue in full force and effect until
specifically released by the Bank in writing. The security interest created hereby shall secure all of the Guarantor's obligations under this Guaranty.



	6.
	Right of Foreclosure. The Bank may foreclose, either by judicial foreclosure or by exercise of power of sale, any deed of trust securing
any Indebtedness even though such foreclosure may destroy or diminish the Guarantor's rights against the Debtor. The Guarantor shall be liable to the Bank for any part of any Indebtedness remaining
unpaid after any such foreclosure whether or not such foreclosure was for fair market value.



	7.
	Subordination. Any indebtedness of the Debtor or any endorser, cosigner, other guarantor or other person liable on any Indebtedness now
or hereafter owed to the Guarantor is hereby subordinated to the Indebtedness. Such indebtedness owed to the Guarantor shall, if the Bank so requests, be collected, enforced and received by the
Guarantor as trustee for the Bank and be paid 


3







 

over
to the Bank on account of the Indebtedness but without reducing or affecting in any manner the liability of the Guarantor set forth herein. Should the Guarantor fail to collect the proceeds of
any such indebtedness owed to it and pay the proceeds to the Bank, the Bank, as the Guarantor's attorney-in-fact, may do such acts and sign such documents in the Guarantor's
name as the Bank considers necessary to effect such collection, and Guarantor hereby appoints Bank as Guarantor's attorney-in-fact for such purposes. 



	8.
	Invalid, Fraudulent or Preferential Payments. The Guarantor agrees that, to the extent the Debtor or any endorser, cosigner, other
guarantor or other person liable on any Indebtedness makes a payment or payments to, or is credited for any payment or payments made for or on behalf of the Debtor to the Bank, which payment or
payments, or any part thereof, is subsequently invalidated, determined to be fraudulent or preferential, set aside or required to be repaid to any trustee, receiver, assignee or any other party
whether under any bankruptcy, state or federal law or under any common law or equitable cause or otherwise, then, to the extent thereof, the obligation or part thereof intended to be satisfied thereby
shall be revived, reinstated and continued in full force and effect as if such payment or payments had not originally been made or credited.



	9.
	Joint and Several Obligations; Independent Obligations. If more than one Guarantor signs
this Guaranty, the obligations hereunder are joint and several. The Guarantor's obligations hereunder are independent of the obligations of the Debtor or any endorser, cosigner, other guarantor or
other person liable on any Indebtedness and a separate action or actions may be brought and prosecuted against the Guarantor on any Indebtedness.



	10.

representation made by the Bank, or any employee, agent or representative of the Bank, with respect to the status, financial condition or other matters related to the Debtor or the relationship
between the Debtor and the Bank.
