Borrower acknowledges that if Borrower fails to timely furnish Lender with any financial record(s) required by this Agreement or otherwise fails to timely perform any other term, obligation or covenant required by this Agreement and Related Documents (singularly and collectively “Non-Compliance”), Lender will incur costs and damages as a result of Borrower’s Non-Compliance, and in consideration of such costs and damages, Borrower agrees to pay Lender a fee equal to 2.500% per annum of the then outstanding loan balance, calculated based on a 30 day month over 360 days per year (“Predetermined Fee Amount”).  Any fee under this section will be imposed monthly in the Predetermined Fee Amount and due on the interest payment due date until the Non-Compliance is cured by Borrower.  A Predetermined Fee Amount will be calculated and imposed in accordance with this section for each recurring event of Non-Compliance.

RECOVERY OF ADDITIONAL COSTS.  If the imposition of or any change in any law, rule, regulation, guideline, or generally accepted accounting principle, or the interpretation or application of any thereof by any court, administrative or governmental authority, or standard-setting organization (including any request or policy not having the force of law) shall impose, modify or make applicable any taxes (except federal, state or local income or franchise taxes imposed on Lender), reserve requirements, capital adequacy requirements or other obligations which would  (A)   increase the cost to Lender for extending or maintaining the credit facilities to which this Agreement relates,  (B)   reduce the amounts payable to Lender under this

Agreement or  the Related Documents, or  (C)  reduce the rate of return on Lender's capital as a consequence of Lender's obligations with respect to the credit facilities to which this Agreement relates, then Borrower agrees to pay Lender such additional amounts as will compensate Lender therefor, within five (5) days after Lender's written demand for such payment, which demand shall be accompanied by an explanation of such imposition or charge and a calculation in reasonable detail of the additional amounts payable by Borrower, which explanation and calculations shall be conclusive in the absence of manifest error.

LENDER'S EXPENDITURES.  If any action or proceeding is commenced that would materially affect Lender's interest in the Collateral or if Borrower fails to comply with any provision of this Agreement or any Related Documents, including but not limited to Borrower's failure to discharge or pay when due any amounts Borrower is required to discharge or pay under this Agreement or any Related Documents, Lender on Borrower's behalf may (but shall not be obligated to) take any action that Lender deems appropriate, including but not limited to discharging or paying all taxes, liens, security interests, encumbrances and other claims, at any time levied or placed on any Collateral and paying all costs for insuring, maintaining and preserving any Collateral.  All such expenditures incurred or paid by Lender for such purposes will then bear interest at the rate charged under the Note from the date incurred or paid by Lender to the date of repayment by Borrower.  All such expenses will become a part of the Indebtedness and, at Lender's option, will  (A)  be payable on demand;  (B)  be added to the balance of the Note and be apportioned among and be payable with any installment payments to become due during either  (1)  the term of any applicable insurance policy; or  (2)  the remaining term of the Note; or  (C)  be treated as a balloon payment which will be due and payable at the Note's maturity.

Continuity of Operations.  (1)  Engage in any business activities substantially different than those in which Borrower is presently engaged,  (2)  cease operations, liquidate, merge, transfer, acquire or consolidate with any other entity, change its name, dissolve or transfer or sell Collateral out of the ordinary course of business, or  (3)  pay any dividends on Borrower's stock (other than dividends payable in its stock), provided, however that notwithstanding the foregoing, but only so long as no Event of Default has occurred and is continuing or would result from the payment of dividends, if Borrower is a "Subchapter S Corporation" (as defined in the Internal Revenue Code of 1986, as amended), Borrower may pay cash dividends on its stock to its shareholders from time to time in amounts necessary to enable the shareholders to pay income taxes and make estimated income tax payments to satisfy their liabilities under federal and state law which arise solely from their status as Shareholders of a Subchapter S Corporation because of their ownership of shares of Borrower's stock, or purchase or retire any of Borrower's outstanding shares or alter or amend Borrower's capital structure.

Loans, Acquisitions and Guaranties.  (1)  Loan, invest in or advance money or assets to any other person, enterprise or entity,  (2)  purchase, create or acquire any interest in any other enterprise or entity, or  (3)  incur any obligation as surety or guarantor other than in the ordinary course of business.

Agreements.  Enter into any agreement containing any provisions which would be violated or breached by the performance of Borrower's obligations under this Agreement or in connection herewith.

CESSATION OF ADVANCES.  If Lender has made any commitment to make any Loan to Borrower, whether under this Agreement or under any other agreement, Lender shall have no obligation to make Loan Advances or to disburse Loan proceeds if:  (A)  Borrower or any Guarantor is in default under the terms of this Agreement or any of the Related Documents or any other agreement that Borrower or any Guarantor has with Lender;  (B)  Borrower or any Guarantor dies, becomes incompetent or becomes insolvent, files a petition in bankruptcy or similar proceedings, or is adjudged a bankrupt;  (C)  there occurs a material adverse change in Borrower's financial condition, in the financial condition of any Guarantor, or in the value of any Collateral securing any Loan; or  (D)  any Guarantor seeks, claims or otherwise attempts to limit, modify or revoke such Guarantor's guaranty of the Loan or any other loan with Lender.

DEFAULT.  Each of the following shall constitute an Event of Default under this Agreement:

Payment Default.  Borrower fails to make any payment when due under the Loan.

Other Defaults.  Borrower fails to comply with or to perform any other term, obligation, covenant or condition contained in this Agreement or in any of the Related Documents or to comply with or to perform any term, obligation, covenant or condition contained in any other agreement between Lender and Borrower.

Default in Favor of Third Parties.  Borrower or any Grantor defaults under any loan, extension of credit, security agreement, purchase or sales agreement, or any other agreement, in favor of any other creditor or person that may materially affect any of Borrower's or any Grantor's property or Borrower's or any Grantor's ability to repay the Loans or perform their respective obligations under this Agreement or any of the Related Documents.

False Statements.  Any warranty, representation or statement made or furnished to Lender by Borrower or on Borrower's behalf under this Agreement or the Related Documents is false or misleading in any material respect, either now or at the time made or furnished or becomes false or misleading at any time thereafter.

Insolvency.  The dissolution or termination of Borrower's existence as a going business, the insolvency of Borrower, the appointment of a receiver for any part of Borrower's property, any assignment for the benefit of creditors, any type of creditor workout, or the commencement of any proceeding under any bankruptcy or insolvency laws by or against Borrower.

Defective Collateralization.  This Agreement or any of the Related Documents ceases to be in full force and effect (including failure of any collateral document to create a valid and perfected security interest or lien) at any time and for any reason.

Creditor or Forfeiture Proceedings.  Commencement of foreclosure or forfeiture proceedings, whether by judicial proceeding, self-help, repossession or any other method, by any creditor of Borrower or by any governmental agency against any collateral securing the Loan.  This includes a garnishment of any of Borrower's accounts, including deposit accounts, with Lender.  However, this Event of Default shall not apply if there is a good faith dispute by Borrower as to the validity or reasonableness of the claim which is the basis of the creditor or forfeiture proceeding and if Borrower gives Lender written notice of the creditor or forfeiture proceeding and deposits with Lender monies or a surety bond for the creditor or forfeiture proceeding, in an amount determined by Lender, in its sole discretion, as being an adequate reserve or bond for the dispute.

Events Affecting Guarantor.  Any of the preceding events occurs with respect to any Guarantor of any of the Indebtedness or any Guarantor dies or becomes incompetent, or revokes or disputes the validity of, or liability under, any Guaranty of the Indebtedness.

Change in Ownership.  Any change in ownership of twenty-five percent (25%) or more of the common stock of Borrower.

Adverse Change.  A material adverse change occurs in Borrower's financial condition, or Lender believes the prospect of payment or performance of the Loan is impaired.

Right to Cure.  If any default, other than a default on Indebtedness, is curable and if Borrower or Grantor, as the case may be, has not been given a notice of a similar default within the preceding twelve (12) months, it may be cured if Borrower or Grantor, as the case may be, after Lender sends written notice to Borrower or Grantor, as the case may be, demanding cure of such default:  (1)  cure the default within fifteen (15) days; or  (2)  if the cure requires more than fifteen (15) days, immediately initiate steps which Lender deems in Lender's sole discretion to be sufficient to cure the default and thereafter continue and complete all reasonable and necessary steps sufficient to produce compliance as soon as reasonably practical.

Other Defaults Modified. Notwithstanding the section above entitled “Other Defaults”, Borrower fails to comply with or to perform any other term, obligation, covenant or condition contained in this Note or Agreement or in any of the Related Documents between Lender and Borrower; or any shareholder, member, trustor, or any owner of the Borrower also holding a controlling interest in any given entity’s common stock, membership interest, trust interest, or any other ownership interest (“Related Entity”), fails to comply with or to perform any other term, obligation, covenant or condition contained in any other agreement between Lender and the Related Entity.

EFFECT OF AN EVENT OF DEFAULT.  If any Event of Default shall occur, except where otherwise provided in this Agreement or the Related Documents, all commitments and obligations of Lender under this Agreement or the Related Documents or any other agreement immediately will terminate (including any obligation to make further Loan Advances or disbursements), and, at Lender's option, all Indebtedness immediately will become due and payable, all without notice of any kind to Borrower, except that in the case of an Event of Default of the type described in the "Insolvency" subsection above, such acceleration shall be automatic and not optional.  In addition, Lender shall have all the rights and remedies provided in the Related Documents or available at law, in equity, or otherwise.  Except as may be prohibited by applicable law, all of Lender's rights and remedies shall be cumulative and may be exercised singularly or concurrently.  Election by Lender to pursue any remedy shall not exclude pursuit of any other remedy, and an election to make expenditures or to take action to perform an obligation of Borrower or of any Grantor shall not affect Lender's right to declare a default and to exercise its rights and remedies.

CHOICE OF VENUE. If there is a lawsuit, the undersigned, and if more than one, each of the undersigned, agree upon Lender's request to submit to the jurisdiction of the courts of Los Angeles County, State of California.

CROSS ACCELERATION. In addition to the due dates and maturity date set forth in the Note, all principal and accrued interest and other amounts owed under this Note shall become due in full at such earlier time, if any, the obligations of Borrower to Lender under that promissory note loan number 30011277,  28933, 18700,  20002400 or that promissory note loan number 30011306 (as such notes may be amended or extended from time to time) are paid in full.

MISCELLANEOUS PROVISIONS.  The following miscellaneous provisions are a part of this Agreement:

Amendments.  This Agreement, together with any Related Documents, constitutes the entire understanding and agreement of the parties as to the matters set forth in this Agreement.  No alteration of or amendment to this Agreement shall be effective unless given in writing and signed by the party or parties sought to be charged or bound by the alteration or amendment.

Attorneys' Fees; Expenses.  Borrower agrees to pay upon demand all of Lender's costs and expenses, including Lender's attorneys' fees and Lender's legal expenses, incurred in connection with the enforcement of this Agreement.  Lender may hire or pay someone else to help enforce this Agreement, and Borrower shall pay the costs and expenses of such enforcement.  Costs and expenses include Lender's attorneys' fees and legal expenses whether or not there is a lawsuit, including attorneys' fees and legal expenses for bankruptcy proceedings (including efforts to modify or vacate any automatic stay or injunction), appeals, and any anticipated post-judgment collection services.  Borrower also shall pay all court costs and such additional fees as may be directed by the court.

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

Consent to Loan Participation.  Borrower agrees and consents to Lender's sale or transfer, whether now or later, of one or more participation interests in the Loan to one or more purchasers, whether related or unrelated to Lender.  Lender may provide, without any limitation whatsoever, to any one or more purchasers, or potential purchasers, any information or knowledge Lender may have about Borrower or about any other matter relating to the Loan, and Borrower hereby waives any rights to privacy Borrower may have with respect to such matters.  Borrower additionally waives any and all notices of sale of participation interests, as well as all notices of any repurchase of such participation interests.  Borrower also agrees that the purchasers of any such participation interests will be considered as the absolute owners of such interests in the Loan and will have all the rights granted under the participation agreement or agreements governing the sale of such participation interests.  Borrower further waives all rights of offset or counterclaim that it may have now or later against Lender or against any purchaser of such a participation interest and unconditionally agrees that either Lender or such purchaser may enforce Borrower's obligation under the Loan irrespective of the failure or insolvency of any holder of any interest in the Loan.  Borrower further agrees that the purchaser of any such participation interests may enforce its interests irrespective of any personal claims or defenses that Borrower may have against Lender.

Governing Law.  This Agreement will be governed by federal law applicable to Lender and, to the extent not preempted by federal law, the laws of the State of California without regard to its conflicts of law provisions.  This Agreement has been accepted by Lender in the State of California.

No Waiver by Lender.  Lender shall not be deemed to have waived any rights under this Agreement 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 waiver by Lender of a provision of this Agreement shall not prejudice or constitute a waiver of Lender's right otherwise to demand strict compliance with that provision or any other provision of this Agreement.  No prior waiver by Lender, nor any course of dealing between Lender and Borrower, or between Lender and any Grantor, shall constitute a waiver of any of Lender's rights or of any of Borrower's or any Grantor's obligations as to any future transactions.  Whenever the consent of Lender is required under this Agreement, 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 discretion of Lender.

Notices.  Any notice required to be given under this Agreement shall be given in writing, and 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 Agreement.  Any party may change its address for notices under this Agreement 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, Borrower agrees to keep Lender informed at all times of Borrower's current address.  Unless otherwise provided or required by law, if there is more than one Borrower, any notice given by Lender to any Borrower is deemed to be notice given to all Borrowers.

Severability.  If a court of competent jurisdiction finds any provision of this Agreement to be illegal, invalid, or unenforceable as to any circumstance, that finding shall not make the offending provision illegal, invalid, or unenforceable as to any other circumstance.  If feasible, the offending provision shall be considered modified so that it becomes legal, valid and enforceable.  If the offending provision cannot be so modified, it shall be considered deleted from this Agreement.  Unless otherwise required by law, the illegality, invalidity, or unenforceability of any provision of this Agreement shall not affect the legality, validity or enforceability of any other provision of this Agreement.

Subsidiaries and Affiliates of Borrower.  To the extent the context of any provisions of this Agreement makes it appropriate, including without limitation any representation, warranty or covenant, the word "Borrower" as used in this Agreement shall include all of Borrower's subsidiaries and affiliates.  Notwithstanding the foregoing however, under no circumstances shall this Agreement be construed to require Lender to make any Loan or other financial accommodation to any of Borrower's subsidiaries or affiliates.

Successors and Assigns.  All covenants and agreements by or on behalf of Borrower contained in this Agreement or any Related Documents shall bind Borrower's successors and assigns and shall inure to the benefit of Lender and its successors and assigns.  Borrower shall not, however, have the right to assign Borrower's rights under this Agreement or any interest therein, without the prior written consent of Lender.

Survival of Representations and Warranties.  Borrower understands and agrees that in making the Loan, Lender is relying on all representations, warranties, and covenants made by Borrower in this Agreement or in any certificate or other instrument delivered by Borrower to Lender under this Agreement or the Related Documents.  Borrower further agrees that regardless of any investigation made by Lender, all such representations, warranties and covenants will survive the making of the Loan and delivery to Lender of the Related Documents, shall be continuing in nature, and shall remain in full force and effect until such time as Borrower's Indebtedness shall be paid in full, or until this Agreement shall be terminated in the manner provided above, whichever is the last to occur.

Time is of the Essence.  Time is of the essence in the performance of this Agreement.

Waive Jury.  To the extent permitted by applicable law, all parties to this Agreement hereby waive the right to any jury trial in any action, proceeding, or counterclaim brought by any party against any other party.

Oral Agreements Not Effective. This Note or Agreement embodies the entire agreement and understanding between the parties hereto with respect to the subject matter hereof and supersedes all prior oral or written negotiations, agreements and understandings of the parties with respect to the subject matter hereof and shall remain in full force and effect in accordance with its terms and conditions.  Moreover, any subsequent oral statements, negotiations, agreements or understandings of the parties shall not be effective against Lender unless (i) expressly stated in writing, (ii) duly approved and authorized by an appropriate decision making committee of Lender on such terms and conditions as such committee shall deem necessary or appropriate in the committee’s sole and absolute opinion and judgment and (iii) executed by an authorized officer of Lender.  Borrower shall not rely or act on any oral statements, negotiations, agreements or understandings between the parties at anytime whatsoever, including before or during any Lender approval process stated above.  Borrower acknowledges and agrees that Borrower shall be responsible for its own actions, including any detrimental reliance on any oral statements, negotiations, agreements or understandings between the parties and that Lender shall not be liable for any possible claims, counterclaims, demands, actions, causes of action, damages, costs, expenses and liability whatsoever, known or unknown, anticipated or unanticipated, suspected or unsuspected, at law or in equity, originating in whole or in part in connection with any oral statements, negotiations, agreements or understandings between the parties which the Borrower may now or hereafter claim against the Lender.  Neither this Note or Agreement nor any other Related Document, nor any terms hereof or thereof may be amended, supplemented or modified except in accordance with the provisions of this section.  Lender may from time to time, (a) enter into with Borrower written amendments, supplements or modifications hereto and to the Related Documents or (b) waive, on such terms and conditions as Lender may specify in such instrument, any of the requirements of this Note or Agreement or the Related Documents or any Event Default and its consequences, if, but only if, such amendment, supplement, modification or waiver is (i) expressly stated in writing, (ii) duly approved and authorized by an appropriate decision making committee of Lender on such terms and conditions as such committee shall deem necessary or appropriate in the committee’s sole and absolute opinion and judgment and (iii) executed by an authorized officer of Lender.  Then such amendment, supplement, modification or waiver shall be effective only in the specific instance and specific purpose for which given.

Judicial Reference. If the waiver of the right to a trial by jury is not enforceable, the parties hereto agree that any and all disputes or controversies of any nature between them arising at any time shall be decided by a reference to a private judge, who shall be a retired state or federal court judge, mutually selected by the parties or, if they cannot agree, then any party may seek to have a private judge appointed in accordance with California Code of Civil Procedure §§ 638 and 640 (or pursuant to comparable provisions of federal law if the dispute falls within the exclusive jurisdiction of the federal courts). The reference proceedings shall be conducted pursuant to and in accordance with the provisions of California Code of Civil Procedure §§ 638 through 645.1, inclusive. The private judge shall have the power, among others, to grant provisional relief, including without limitation, entering temporary restraining orders, issuing preliminary and permanent injunctions and appointing receivers.  All such proceedings shall be closed to the public and confidential and all records relating thereto shall be permanently sealed. If during the course of any dispute, a party desires to seek provisional relief, but a judge has not been appointed at that point pursuant to the judicial reference procedures, then such party may apply to the Court for such relief. The proceeding before the private judge shall be conducted in the same manner as it would be before a court under the rules of evidence applicable to judicial proceedings. The parties shall be entitled to discovery which shall be conducted in the same manner as it would be before a court under the rules of discovery applicable to judicial proceedings. The private judge shall oversee discovery and may enforce all discovery rules and orders applicable to judicial proceedings in the same manner as a trial court judge. The parties agree that the selected or appointed private judge shall have the power to decide all issues in the action or proceeding, whether of fact or of law, and shall report a statement of decision thereon pursuant to California Code of Civil Procedure § 644(a). Nothing in this paragraph shall limit the right of any party at any time to

exercise self-help remedies, foreclose against collateral, or obtain provisional remedies. The private judge shall also determine all issues relating to the applicability, interpretation, and enforceability of this paragraph.

The parties agree that time is of the essence in conducting the referenced proceedings.  The parties shall promptly and diligently cooperate with one another and the referee, and shall perform such acts as may be necessary to obtain prompt and expeditious resolution of the dispute or controversy in accordance with the terms hereof.  The costs shall be borne equally by the parties.

PROMISSORY NOTE

PROMISE TO PAY.  Amphastar Pharmaceuticals, Inc. ("Borrower") promises to pay to East West Bank ("Lender"), or order, in lawful money of the United States of America, the principal amount of Nine Million & 00/100 Dollars ($9,000,000.00), together with interest on the unpaid principal balance from May 18, 2017, until paid in full.

PAYMENT.  Subject to any payment changes resulting from changes in the Index, Borrower will pay this loan in accordance with the following payment schedule:

Borrower will make principal payments on this loan as set forth in the attached Exhibit "A". Borrower's first principal payment is due July 5, 2017, and all subsequent principal payments are due on the same day of each month after that.  In addition, Borrower will pay regular monthly payments of all accrued unpaid interest due as of each payment date, beginning July 5, 2017 with all subsequent interest payments to be due on the same day of each month after that.  Borrower's final payment due June 5, 2027, will be for all principal and all accrued interest not yet paid.

 Unless otherwise agreed or required by applicable law, payments will be applied first to any accrued unpaid interest; then to principal; then to any late charges; and then to any unpaid collection costs.  Borrower will pay Lender at Lender's address shown above or at such other place as Lender may designate in writing.

VARIABLE INTEREST RATE.  The interest rate on this Note is subject to change from time to time based on changes in an independent index which is the rate quoted by Lender for successive 1 month LIBOR Interest Periods.  “LIBOR Interest Period” means a period of 1 month, determined and adjusted by Lender in accordance with the custom and practice for transactions in Eurodollars conducted in London, England and the provisions of this section.  Such interest rate shall be equivalent to Lender’s LIBOR Rate which is that rate determined by Lender’s Treasury Desk to be the Interbank lending rate for a period of 1-month which appears on the Bloomberg Screen B TMM Page under the heading “LIBOR Fix” as of 11:00 am (London Time) on the second Business Day prior to the first day of such period (adjusted for any and all assessments, surcharges and reserve requirements).  If such interest rate shall cease to be available from the described Bloomberg report, the London interbank offered rate shall be determined from such financial reporting service as Lender shall reasonably determine and use with respect to its other loan facilities on which interest is determined based on the London interbank offered rate. The LIBOR Rate shall be adjusted to occur on the same day as the payment due date as set forth in the section entitled Payment Due Date below (the "Index").  The Index is not necessarily the lowest rate charged by Lender on its loans.  If the Index becomes unavailable during the term of this loan, Lender may designate a substitute index after notifying Borrower.  Lender will tell Borrower the current Index rate upon Borrower's request.  The interest rate change will not occur more often than each 1 month.  Borrower understands that Lender may make loans based on other rates as well.  The Index currently is 0.999% per annum.  Interest on the unpaid principal balance of this Note will be calculated as described in the "INTEREST CALCULATION METHOD" paragraph using a rate of 2.500 percentage points over the Index, resulting in an initial rate of 3.499%.  NOTICE:  Under no circumstances will the interest rate on this Note be more than the maximum rate allowed by applicable law.  Whenever increases occur in the interest rate, Lender, at its option, may do one or more of the following:  (A)  increase Borrower's payments to ensure Borrower's loan will pay off by its original final maturity date,  (B)  increase Borrower's payments to cover accruing interest,  (C)  increase the number of Borrower's payments, and  (D)  continue Borrower's payments at the same amount and increase Borrower's final payment.

INTEREST CALCULATION METHOD.  Interest on this Note is computed 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.  All interest payable under this Note is computed using this method.

BUSINESS DAY. Any day other than a Saturday or a Sunday or any day on which commercial banks in Los Angeles, California, are authorized or required to close.

PAYMENT DUE DATE. If any payment required to be made by the Borrower hereunder becomes due and payable on a day other than a Business Day, the due date thereof shall be extended to the next succeeding Business Day and interest thereon shall be payable at the then applicable rate during such extension.

PREPAYMENT; MINIMUM INTEREST CHARGE.  Borrower agrees that all loan fees and other prepaid finance charges are earned fully as of the date of the loan and will not be subject to refund upon early payment (whether voluntary or as a result of default), except as otherwise required by law.   In any event, even upon full prepayment of this Note, Borrower understands that Lender is entitled to a minimum interest charge of $100.00.  Other than Borrower's obligation to pay any minimum interest charge, Borrower may pay without penalty all or a portion of the amount owed earlier than it is due.  Early payments will not, unless agreed to by Lender in writing, relieve Borrower of Borrower's obligation to continue to make payments under the payment schedule.  Rather, early payments will reduce the principal balance due and may result in Borrower's making fewer payments.  Borrower agrees not to send Lender payments marked "paid in full", "without recourse", or similar language.  If Borrower sends such a payment, Lender may accept it without losing any of Lender's rights under this Note, and Borrower will remain obligated to pay any further amount owed to Lender.  All written communications concerning disputed amounts, including any check or other payment instrument that indicates that the payment constitutes "payment in full" of the amount owed or that is tendered with other conditions or limitations or as full satisfaction of a disputed amount must be mailed or delivered to:  East West Bank, Loan Service Department, 9300 Flair Drive, 6th Floor El Monte, CA  91731.

LATE CHARGE.  If a payment is 11 days or more late, Borrower will be charged 6.000% of the unpaid portion of the regularly scheduled payment or $5.00, whichever is greater.

INTEREST AFTER DEFAULT.  Upon default, the interest rate on this Note shall, if permitted under applicable law, immediately increase by adding an additional 5.000 percentage point margin ("Default Rate Margin").  The Default Rate Margin shall also apply to each succeeding interest rate change that

would have applied had there been no default.

DEFAULT.  Each of the following shall constitute an event of default ("Event of Default") under this Note:

Payment Default.  Borrower fails to make any payment when due under this Note.

Other Defaults.  Borrower fails to comply with or to perform any other term, obligation, covenant or condition contained in this Note or in any of the related documents or to comply with or to perform any term, obligation, covenant or condition contained in any other agreement between Lender and Borrower.

Default in Favor of Third Parties.  Borrower or any Grantor defaults under any loan, extension of credit, security agreement, purchase or sales agreement, or any other agreement, in favor of any other creditor or person that may materially affect any of Borrower's property or Borrower's ability to repay this Note or perform Borrower's obligations under this Note or any of the related documents.

False Statements.  Any warranty, representation or statement made or furnished to Lender by Borrower or on Borrower's behalf under this Note or the related documents is false or misleading in any material respect, either now or at the time made or furnished or becomes false or misleading at any time thereafter.

Insolvency.  The dissolution or termination of Borrower's existence as a going business, the insolvency of Borrower, the appointment of a receiver for any part of Borrower's property, any assignment for the benefit of creditors, any type of creditor workout, or the commencement of any proceeding under any bankruptcy or insolvency laws by or against Borrower.

Creditor or Forfeiture Proceedings.  Commencement of foreclosure or forfeiture proceedings, whether by judicial proceeding, self-help, repossession or any other method, by any creditor of Borrower or by any governmental agency against any collateral securing the loan.  This includes a garnishment of any of Borrower's accounts, including deposit accounts, with Lender.  However, this Event of Default shall not apply if there is a good faith dispute by Borrower as to the validity or reasonableness of the claim which is the basis of the creditor or forfeiture proceeding and if Borrower gives Lender written notice of the creditor or forfeiture proceeding and deposits with Lender monies or a surety bond for the creditor or forfeiture proceeding, in an amount determined by Lender, in its sole discretion, as being an adequate reserve or bond for the dispute.

Events Affecting Guarantor.  Any of the preceding events occurs with respect to any guarantor, endorser, surety, or accommodation party of any of the indebtedness or any guarantor, endorser, surety, or accommodation party dies or becomes incompetent, or revokes or disputes the validity of, or liability under, any guaranty of the indebtedness evidenced by this Note.

Change In Ownership.  Any change in ownership of twenty-five percent (25%) or more of the common stock of Borrower.

Adverse Change.  A material adverse change occurs in Borrower's financial condition, or Lender believes the prospect of payment or performance of this Note is impaired.

Cure Provisions.  If any default, other than a default in payment, is curable and if Borrower has not been given a notice of a breach of the same provision of this Note within the preceding twelve (12) months, it may be cured if Borrower, after Lender sends written notice to Borrower demanding cure of such default:  (1)  cures the default within fifteen (15) days; or  (2)  if the cure requires more than fifteen (15) days, immediately initiates steps which Lender deems in Lender's sole discretion to be sufficient to cure the default and thereafter continues and completes all reasonable and necessary steps sufficient to produce compliance as soon as reasonably practical.

OTHER DEFAULTS MODIFIED. Notwithstanding the section above entitled “Other Defaults”, Borrower fails to comply with or to perform any other term, obligation, covenant or condition contained in this Note or Agreement or in any of the Related Documents between Lender and Borrower; or any shareholder, member, trustor, or any owner of the Borrower also holding a controlling interest in any given entity’s common stock, membership interest, trust interest, or any other ownership interest (“Related Entity”), fails to comply with or to perform any other term, obligation, covenant or condition contained in any other agreement between Lender and the Related Entity.

LENDER'S RIGHTS.  Upon default, Lender may declare the entire unpaid principal balance under this Note and all accrued unpaid interest immediately due, and then Borrower will pay that amount. 

JUDICIAL REFERENCE. If the waiver of the right to a trial by jury is not enforceable, the parties hereto agree that any and all disputes or controversies of any nature between them arising at any time shall be decided by a reference to a private judge, who shall be a retired state or federal court judge, mutually selected by the parties or, if they cannot agree, then any party may seek to have a private judge appointed in accordance with California Code of Civil Procedure §§ 638 and 640 (or pursuant to comparable provisions of federal law if the dispute falls within the exclusive jurisdiction of the federal courts). The reference proceedings shall be conducted pursuant to and in accordance with the provisions of California Code of Civil Procedure §§ 638 through 645.1, inclusive. The private judge shall have the power, among others, to grant provisional relief, including without limitation, entering temporary restraining orders, issuing preliminary and permanent injunctions and appointing receivers.  All such proceedings shall be closed to the public and confidential and all records relating thereto shall be permanently sealed. If during the course of any dispute, a party desires to seek provisional relief, but a judge has not been appointed at that point pursuant to the judicial reference procedures, then such party may apply to the Court for such relief. The proceeding before the private judge shall be conducted in the same manner as it would be before a court under the rules of evidence applicable to judicial proceedings. The parties shall be entitled to discovery which shall be conducted in the same manner as it would be before a court under the rules of discovery applicable to judicial proceedings. The private judge shall oversee discovery and may enforce all discovery rules and orders applicable to judicial proceedings in the same manner as a trial court judge. The parties agree that the selected or appointed private judge shall have the power to decide all issues in the action or proceeding, whether of fact or of law, and shall report a statement of decision thereon pursuant to California Code of Civil Procedure § 644(a). Nothing in this paragraph shall limit the right of any party at any time to exercise self-help remedies, foreclose against collateral, or obtain provisional remedies. The private judge shall also determine all issues relating to the applicability, interpretation, and enforceability of this paragraph.

The parties agree that time is of the essence in conducting the referenced proceedings.  The parties shall promptly and diligently cooperate with one another and the referee, and shall perform such acts as may be necessary to obtain prompt and expeditious resolution of the dispute or controversy in accordance with the terms hereof.  The costs shall be borne equally by the parties.

ATTORNEYS' FEES; EXPENSES.  Lender may hire or pay someone else to help collect this Note if Borrower does not pay.  Borrower will pay Lender that amount.  This includes, subject to any limits under applicable law, Lender's attorneys' fees and Lender's legal expenses, whether or not there is a

lawsuit, including attorneys' fees, expenses for bankruptcy proceedings (including efforts to modify or vacate any automatic stay or injunction), and appeals.  Borrower also will pay any court costs, in addition to all other sums provided by law.

JURY WAIVER.  To the extent permitted by applicable law, Lender and Borrower hereby waive the right to any jury trial in any action, proceeding, or counterclaim brought by either Lender or Borrower against the other.

GOVERNING LAW.  This Note will be governed by federal law applicable to Lender and, to the extent not preempted by federal law, the laws of the State of California without regard to its conflicts of law provisions.  This Note has been accepted by Lender in the State of California.

DISHONORED ITEM FEE.  Borrower will pay a fee to Lender of $25.00 if Borrower makes a payment on Borrower's loan and the check or preauthorized charge with which Borrower pays is later dishonored.

COLLATERAL.  Borrower acknowledges this Note is secured by the following collateral described in the security instruments listed herein:

(A)  a Deed of Trust dated May 18, 2017, to a trustee in favor of Lender on real property located in San Bernardino County, State of California.  That agreement contains the following due on sale provision:  Lender may, at Lender's option, declare immediately due and payable all sums secured by the Deed of Trust upon the sale or transfer, without Lender's prior written consent, of all or any part of the Real Property, or any interest in the Real Property.  A "sale or transfer" means the conveyance of Real Property or any right, title or interest in the Real Property; whether legal, beneficial or equitable; whether voluntary or involuntary; whether by outright sale, deed, installment sale contract, land contract, contract for deed, leasehold interest with a term greater than three (3) years, lease-option contract, or by sale, assignment, or transfer of any beneficial interest in or to any land trust holding title to the Real Property, or by any other method of conveyance of an interest in the Real Property.  If any Borrower is a corporation, partnership or limited liability company, transfer also includes any change in ownership of more than twenty-five percent (25%) of the voting stock, partnership interests or limited liability company interests, as the case may be, of such Borrower.  However, this option shall not be exercised by Lender if such exercise is prohibited by applicable law.

ADDENDUM TO PROMISSORY NOTE - INTEREST RATE SWAP

This ADDENDUM TO PROMISSORY NOTE - INTEREST RATE SWAP is attached to and by this reference is made a part of the Promissory Note, dated May 18, 2017, and executed in connection with a loan or other financial accommodations between EAST WEST BANK and Amphastar Pharmaceuticals, Inc.

The following sentence is hereby added to the paragraph headed "PREPAYMENT; MINIMUM INTEREST CHARGE":

"Notwithstanding the provisions of this paragraph, Borrower must consult with Lender prior to making any prepayments when a Financial Contract has been executed between Borrower and Lender in connection with this Note.  Borrower acknowledges that partial prepayments of the Note will require the Financial Contract to be amended, and full prepayment will terminate the Financial Contract. Full and partial prepayments will trigger an early termination valuation under the Financial Contract. Thus, an early termination fee may occur under the Financial Contract upon partial and full prepayment of the Note.” 

Notwithstanding the provisions of this paragraph, Borrower shall remain obligated to pay any fee due and owing under the Financial Contract, including but not limited to any fee owed upon early termination of the Financial Contract.

The subparagraph headed "Other Defaults," in the paragraph headed "DEFAULT," is hereby amended to read as follows:

"Other Defaults.  Borrower fails to comply with or to perform any other term, obligation, covenant or condition contained in this Note or in any of the Related Documents or to comply with or to perform any term, obligation, covenant or condition contained in any other agreement including but not limited to any Financial Contract between Lender and Borrower."

The subparagraph headed "Cure Provisions," in the paragraph headed "DEFAULT," is hereby amended to read as follows:

"Cure Provisions.  If any default, other than a default in payment or in a Financial Contract, is curable and if Borrower has not been given a notice of a breach of the same provision of this Note within the preceding twelve (12) months, it may be cured if Borrower, after Lender sends written notice to Borrower demanding cure of such default: (1) cures the default within fifteen (15) days; or (2) if the cure requires more than fifteen (15) days, immediately initiates steps which Lender deems in Lender's sole discretion to be sufficient to cure the default and thereafter continues and completes all reasonable and necessary steps sufficient to produce compliance as soon as reasonably practical."

The following sentence is hereby added to the paragraph headed "COLLATERAL”:

Borrower’s obligations under the Financial Contract shall be secured by the Deed of Trust and Commercial Security Agreement described in this section.

The following DEFINITION is hereby added to the Note:

"Financial Contract.  The words "Financial Contract" mean (1) an agreement (including terms and conditions incorporated by reference therein) which is a rate swap agreement, basis swap, forward rate agreement, commodity swap, commodity option, equity or equity index swap, bond option, interest rate option, foreign exchange agreement, rate cap agreement, rate floor agreement, rate collar agreement, currency swap agreement, cross-currency rate swap agreement, currency option, any other similar agreement (including any option to enter into any of the foregoing); or (2) any combination of the foregoing.

Financial Contract Interest Rate.  If Borrower enters into a Financial Contract, the applicable interest rate on the Note as of the effective date of the Financial Contract shall be as follows:

VARIABLE INTEREST RATE for Financial Contract Interest Rate.  The interest rate on this Note is subject to change from time to time based on changes in an independent index which is the rate quoted by Lender for successive 1 month LIBOR Interest Periods.  “LIBOR Interest Period” means a period of 1 month, determined and adjusted by Lender in accordance with the custom and practice for transactions in Eurodollars conducted in London, England and the provisions of this section.  Such interest rate shall be equivalent to Lender’s LIBOR Rate which is that rate determined by Lender’s Treasury Desk to be the Interbank lending rate for a period of 1-month which appears on the Bloomberg Screen B TMM Page under the heading “LIBOR Fix” as of 11:00 am (London Time) on the second Business Day prior to the first day of such period (adjusted for any and all assessments, surcharges and reserve requirements).  If such interest rate shall cease to be available from the described Bloomberg report, the London interbank offered rate shall be determined from such financial reporting service as Lender shall reasonably determine and use with respect to its other loan facilities on which interest is determined based on the London interbank offered rate. The LIBOR Rate shall be adjusted to occur on the same day as the payment due date as set forth in the section entitled Payment Due Date below (the "Index").  The Index is not necessarily the lowest rate charged by Lender on its loans.  If the Index becomes unavailable during the term of this loan, Lender may designate a substitute index after notifying Borrower.  Lender will tell Borrower the current Index rate upon Borrower's request.  The interest rate change will not occur more often than each 1 month.  Borrower understands that Lender may make loans based on other rates as well.  The Index currently is 0.999% per annum.  Interest on the unpaid principal balance of this Note will be calculated as described in the "INTEREST CALCULATION METHOD" paragraph using a rate of 2.500 percentage points over the Index, resulting in an initial rate of 3.499%.  NOTICE:  Under no circumstances will the interest rate on this Note be more than the maximum rate allowed by applicable law.  Whenever increases occur in the interest rate, Lender, at its option, may do one or more of the following:  (A)  increase Borrower's payments to ensure Borrower's loan will pay off by its original final maturity date,  (B)  increase Borrower's payments to cover accruing interest,  (C)  increase the number of Borrower's payments, and  (D)  continue Borrower's payments at the same amount and increase Borrower's final payment.

Financial Contract Interest After Default.  If Borrower enters into a Financial Contract, the applicable interest rate upon default will be calculated as provided for in the section entitled "INTEREST AFTER DEFAULT" of the Note.

Financial Contract as a Separate and Distinct Obligation. Notwithstanding any contrary provisions of the Loan Documents, and without impairing Lender’s right under the Loan Documents, the amounts payable by Borrower under the Financial Contracts shall be, and at all times shall remain, separate

and independent debts owed by Borrower in accordance with the terms of the Financial Contract.

THIS ADDENDUM TO PROMISSORY NOTE - INTEREST RATE SWAP IS EXECUTED ON MAY 18, 2017.

under this Agreement.  Unless waived by Lender, all proceeds from any disposition of the Collateral (for whatever reason) shall be held in trust for Lender and shall not be commingled with any other funds; provided however, this requirement shall not constitute consent by Lender to any sale or other disposition.  Upon receipt, Grantor shall immediately deliver any such proceeds to Lender.

Title.  Grantor represents and warrants to Lender that Grantor holds good and marketable title to the Collateral, free and clear of all liens and encumbrances except for the lien of this Agreement.  No financing statement covering any of the Collateral is on file in any public office other than those which reflect the security interest created by this Agreement or to which Lender has specifically consented.  Grantor shall defend Lender's rights in the Collateral against the claims and demands of all other persons.

Repairs and Maintenance.  Grantor agrees to keep and maintain, and to cause others to keep and maintain, the Collateral in good order, repair and condition at all times while this Agreement remains in effect.  Grantor further agrees to pay when due all claims for work done on, or services rendered or material furnished in connection with the Collateral so that no lien or encumbrance may ever attach to or be filed against the Collateral.

Inspection of Collateral.  Lender and Lender's designated representatives and agents shall have the right at all reasonable times to examine and inspect the Collateral wherever located.

Taxes, Assessments and Liens.  Grantor will pay when due all taxes, assessments and liens upon the Collateral, its use or operation, upon this Agreement, upon any promissory note or notes evidencing the Indebtedness, or upon any of the other Related Documents.  Grantor may withhold any such payment or may elect to contest any lien if Grantor is in good faith conducting an appropriate proceeding to contest the obligation to pay and so long as Lender's interest in the Collateral is not jeopardized in Lender's sole opinion.  If the Collateral is subjected to a lien which is not discharged within fifteen (15) days, Grantor shall deposit with Lender cash, a sufficient corporate surety bond or other security satisfactory to Lender in an amount adequate to provide for the discharge of the lien plus any interest, costs, attorneys' fees or other charges that could accrue as a result of foreclosure or sale of the Collateral.  In any contest Grantor shall defend itself and Lender and shall satisfy any final adverse judgment before enforcement against the Collateral.  Grantor shall name Lender as an additional obligee under any surety bond furnished in the contest proceedings.  Grantor further agrees to furnish Lender with evidence that such taxes, assessments, and governmental and other charges have been paid in full and in a timely manner.  Grantor may withhold any such payment or may elect to contest any lien if Grantor is in good faith conducting an appropriate proceeding to contest the obligation to pay and so long as Lender's interest in the Collateral is not jeopardized.

Compliance with Governmental Requirements.  Grantor shall comply promptly with all laws, ordinances, rules and regulations of all governmental authorities, now or hereafter in effect, applicable to the ownership, production, disposition, or use of the Collateral, including all laws or regulations relating to the undue erosion of highly-erodible land or relating to the conversion of wetlands for the production of an agricultural product or commodity.  Grantor may contest in good faith any such law, ordinance or regulation and withhold compliance during any proceeding, including appropriate appeals, so long as Lender's interest in the Collateral, in Lender's opinion, is not jeopardized.

Hazardous Substances.  Grantor represents and warrants that the Collateral never has been, and never will be so long as this Agreement remains a lien on the Collateral, used in violation of any Environmental Laws or for the generation, manufacture, storage, transportation, treatment, disposal, release or threatened release of any Hazardous Substance.  The representations and warranties contained herein are based on Grantor's due diligence in investigating the Collateral for Hazardous Substances.  Grantor hereby  (1)  releases and waives any future claims against Lender for indemnity or contribution in the event Grantor becomes liable for cleanup or other costs under any Environmental Laws, and  (2)  agrees to indemnify, defend, and hold harmless Lender against any and all claims and losses resulting from a breach of this provision of this Agreement.  This obligation to indemnify and defend shall survive the payment of the Indebtedness and the satisfaction of this Agreement.

Maintenance of Casualty Insurance.  Grantor shall procure and maintain all risks insurance, including without limitation fire, theft and liability coverage together with such other insurance as Lender may require with respect to the Collateral, in form, amounts, coverages and basis reasonably acceptable to Lender and issued by a company or companies reasonably acceptable to Lender.  Grantor, upon request of Lender, will deliver to Lender from time to time the policies or certificates of insurance in form satisfactory to Lender, including stipulations that coverages will not be cancelled or diminished without at least thirty (30) days' prior written notice to Lender and not including any disclaimer of the insurer's liability for failure to give such a notice.  Each insurance policy also shall include an endorsement providing that coverage in favor of Lender will not be impaired in any way by any act, omission or default of Grantor or any other person.  In connection with all policies covering assets in which Lender holds or is offered a security interest, Grantor will provide Lender with such loss payable or other endorsements as Lender may require.  If Grantor at any time fails to obtain or maintain any insurance as required under this Agreement, Lender may (but shall not be obligated to) obtain such insurance as Lender deems appropriate, including if Lender so chooses "single interest insurance," which will cover only Lender's interest in the Collateral.

Application of Insurance Proceeds.  Grantor shall promptly notify Lender of any loss or damage to the Collateral if the estimated cost of repair or replacement exceeds $10,000.00, whether or not such casualty or loss is covered by insurance.  Lender may make proof of loss if Grantor fails to do so within fifteen (15) days of the casualty.  All proceeds of any insurance on the Collateral, including accrued proceeds thereon, shall be held by Lender as part of the Collateral.  If Lender consents to repair or replacement of the damaged or destroyed Collateral, Lender shall, upon satisfactory proof of expenditure,  pay or reimburse Grantor from the proceeds for the reasonable cost of repair or restoration.  If Lender does not consent to repair or replacement of the Collateral, Lender shall retain a sufficient amount of the proceeds to pay all of the Indebtedness, and shall pay the balance to Grantor.  Any proceeds which have not been disbursed within six (6) months after their receipt and which Grantor has not committed to the repair or restoration of the Collateral shall be used to prepay the Indebtedness.

Insurance Reserves.  Lender may require Grantor to maintain with Lender reserves for payment of insurance premiums, which reserves shall be created by monthly payments from Grantor of a sum estimated by Lender to be sufficient to produce, at least fifteen (15) days before the premium due date, amounts at least equal to the insurance premiums to be paid.  If fifteen (15) days before payment is due, the reserve funds are insufficient, Grantor shall upon demand pay any deficiency to Lender.  The reserve funds shall be held by Lender as a general deposit and shall constitute a non-interest-bearing account which Lender may satisfy by payment of the insurance premiums required to be paid by Grantor as they become due.  Lender does not hold the reserve funds in trust for Grantor, and Lender is not the agent of Grantor for payment of the insurance premiums required to be paid by Grantor.  The responsibility for the payment of premiums shall remain Grantor's sole responsibility.

Insurance Reports.  Grantor, upon request of Lender, shall furnish to Lender reports on each existing policy of insurance showing such information as Lender may reasonably request including the following:  (1)  the name of the insurer;  (2)  the risks insured;  (3)  the amount of the policy;  (4)  the property insured;  (5)  the then current value on the basis of which insurance has been obtained and the manner of determining that value; and  (6)  the expiration date of the policy.  In addition, Grantor shall upon request by Lender (however not more often than annually) have an independent appraiser satisfactory to Lender determine, as applicable, the cash value or replacement cost of the Collateral.

Financing Statements.  Grantor authorizes Lender to file a UCC financing statement, or alternatively, a copy of this Agreement to perfect Lender's security interest.  At Lender's request, Grantor additionally agrees to sign all other documents that are necessary to perfect, protect, and continue Lender's security interest in the Property.  This includes making sure Lender is shown as the first and only security interest holder on the title covering the Property.  Grantor will pay all filing fees, title transfer fees, and other fees and costs involved unless prohibited by law or unless Lender is required by law to pay such fees and costs.  Grantor irrevocably appoints Lender to execute documents necessary to transfer title if there is a default.  Lender may file a copy of this Agreement as a financing statement.

GRANTOR'S RIGHT TO POSSESSION.  Until default, Grantor may have possession of the tangible personal property and beneficial use of all the Collateral and may use it in any lawful manner not inconsistent with this Agreement or the Related Documents, provided that Grantor's right to possession and beneficial use shall not apply to any Collateral where possession of the Collateral by Lender is required by law to perfect Lender's security interest in such Collateral.  If Lender at any time has possession of any Collateral, whether before or after an Event of Default, Lender shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral if Lender takes such action for that purpose as Grantor shall request or as Lender, in Lender's sole discretion, shall deem appropriate under the circumstances, but failure to honor any request by Grantor shall not of itself be deemed to be a failure to exercise reasonable care.  Lender shall not be required to take any steps necessary to preserve any rights in the Collateral against prior parties, nor to protect, preserve or maintain any security interest given to secure the Indebtedness.

LENDER'S EXPENDITURES.  If any action or proceeding is commenced that would materially affect Lender's interest in the Collateral or if Grantor fails to comply with any provision of this Agreement or any Related Documents, including but not limited to Grantor's failure to discharge or pay when due any amounts Grantor is required to discharge or pay under this Agreement or any Related Documents, Lender on Grantor's behalf may (but shall not be obligated to) take any action that Lender deems appropriate, including but not limited to discharging or paying all taxes, liens, security interests, encumbrances and other claims, at any time levied or placed on the Collateral and paying all costs for insuring, maintaining and preserving the Collateral.  All such expenditures incurred or paid by Lender for such purposes will then bear interest at the rate charged under the Note from the date incurred or paid by Lender to the date of repayment by Grantor.  All such expenses will become a part of the Indebtedness and, at Lender's option, will  (A)  be payable on demand;  (B)  be added to the balance of the Note and be apportioned among and be payable with any installment payments to become due during either  (1)  the term of any applicable insurance policy; or  (2)  the remaining term of the Note; or  (C)  be treated as a balloon payment which will be due and payable at the Note's maturity.  The Agreement also will secure payment of these amounts.  Such right shall be in addition to all other rights and remedies to which Lender may be entitled upon Default.

DEFAULT.  Each of the following shall constitute an Event of Default under this Agreement:

Payment Default.  Grantor fails to make any payment when due under the Indebtedness.

Other Defaults.  Grantor fails to comply with or to perform any other term, obligation, covenant or condition contained in this Agreement or in any of the Related Documents or to comply with or to perform any term, obligation, covenant or condition contained in any other agreement between Lender and Grantor.

Default in Favor of Third Parties.  Grantor defaults under any loan, extension of credit, security agreement, purchase or sales agreement, or any other agreement, in favor of any other creditor or person that may materially affect any of Grantor's property or ability to perform Grantor's obligations under this Agreement or any of the Related Documents.

False Statements.  Any warranty, representation or statement made or furnished to Lender by Grantor or on Grantor's behalf under this Agreement or the Related Documents is false or misleading in any material respect, either now or at the time made or furnished or becomes false or misleading at any time thereafter.

Defective Collateralization.  This Agreement or any of the Related Documents ceases to be in full force and effect (including failure of any collateral document to create a valid and perfected security interest or lien) at any time and for any reason.

Insolvency.  The dissolution or termination of Grantor's existence as a going business, the insolvency of Grantor, the appointment of a receiver for any part of Grantor's property, any assignment for the benefit of creditors, any type of creditor workout, or the commencement of any proceeding under any bankruptcy or insolvency laws by or against Grantor.

Creditor or Forfeiture Proceedings.  Commencement of foreclosure or forfeiture proceedings, whether by judicial proceeding, self-help, repossession or any other method, by any creditor of Grantor or by any governmental agency against any collateral securing the Indebtedness.  This includes a garnishment of any of Grantor's accounts, including deposit accounts, with Lender.  However, this Event of Default shall not apply if there is a good faith dispute by Grantor as to the validity or reasonableness of the claim which is the basis of the creditor or forfeiture proceeding and if Grantor gives Lender written notice of the creditor or forfeiture proceeding and deposits with Lender monies or a surety bond for the creditor or forfeiture proceeding, in an amount determined by Lender, in its sole discretion, as being an adequate reserve or bond for the dispute.

Events Affecting Guarantor.  Any of the preceding events occurs with respect to any guarantor, endorser, surety, or accommodation party of any of the Indebtedness or guarantor, endorser, surety, or accommodation party dies or becomes incompetent or revokes or disputes the validity of, or liability under, any Guaranty of the Indebtedness.

Adverse Change.  A material adverse change occurs in Grantor's financial condition, or Lender believes the prospect of payment or performance of the Indebtedness is impaired.

Cure Provisions.  If any default, other than a default in payment, is curable and if Grantor has not been given a notice of a breach of the same provision of this Agreement within the preceding twelve (12) months, it may be cured if Grantor, after Lender sends written notice to Grantor demanding cure of such default:  (1)  cures the default within fifteen (15) days; or  (2)  if the cure requires more than fifteen (15) days, immediately initiates steps which Lender deems in Lender's sole discretion to be sufficient to cure the default and thereafter continues and completes all reasonable and necessary steps sufficient to produce compliance as soon as reasonably practical.

RIGHTS AND REMEDIES ON DEFAULT.  If an Event of Default occurs under this Agreement, at any time thereafter, Lender shall have all the rights of a secured party under the California Uniform Commercial Code.  In addition and without limitation, Lender may exercise any one or more of the following rights and remedies:

Accelerate Indebtedness.  Lender may declare the entire Indebtedness, including any prepayment penalty which Grantor would be required to pay, immediately due and payable, without notice of any kind to Grantor.

Assemble Collateral.  Lender may require Grantor to deliver to Lender all or any portion of the Collateral and any and all certificates of title and other documents relating to the Collateral.  Lender may require Grantor to assemble the Collateral and make it available to Lender at a place to be designated by Lender.  Lender also shall have full power to enter upon the property of Grantor to take possession of and remove the Collateral.  If the Collateral contains other goods not covered by this Agreement at the time of repossession, Grantor agrees Lender may take such other goods, provided that Lender makes reasonable efforts to return them to Grantor after repossession.

Sell the Collateral.  Lender shall have full power to sell, lease, transfer, or otherwise deal with the Collateral or proceeds thereof in Lender's own name or that of Grantor.  Lender may sell the Collateral at public auction or private sale.  Unless the Collateral threatens to decline speedily in value or is of a type customarily sold on a recognized market, Lender will give Grantor, and other persons as required by law, reasonable notice of the time and place of any public sale, or the time after which any private sale or any other disposition of the Collateral is to be made.  However, no notice need be provided to any person who, after Event of Default occurs, enters into and authenticates an agreement waiving that person's right to notification of sale.  The requirements of reasonable notice shall be met if such notice is given at least ten (10) days before the time of the sale or disposition.  All expenses relating to the disposition of the Collateral, including without limitation the expenses of retaking, holding, insuring, preparing for sale and selling the Collateral, shall become a part of the Indebtedness secured by this Agreement and shall be payable on demand, with interest at the Note rate from date of expenditure until repaid.

Appoint Receiver.  Lender shall have the right to have a receiver appointed to take possession of all or any part of the Collateral, with the power to protect and preserve the Collateral, to operate the Collateral preceding foreclosure or sale, and to collect the rents from the Collateral and apply the proceeds, over and above the cost of the receivership, against the Indebtedness.  The receiver may serve without bond if permitted by law.  Lender's right to the appointment of a receiver shall exist whether or not the apparent value of the Collateral exceeds the Indebtedness by a substantial amount.  Employment by Lender shall not disqualify a person from serving as a receiver.

Collect Revenues, Apply Accounts.  Lender, either itself or through a receiver, may collect the payments, rents, income, and revenues from the Collateral.  Lender may at any time in Lender's discretion transfer any Collateral into Lender's own name or that of Lender's nominee and receive the payments, rents, income, and revenues therefrom and hold the same as security for the Indebtedness or apply it to payment of the Indebtedness in such order of preference as Lender may determine.  Insofar as the Collateral consists of accounts, general intangibles, insurance policies, instruments, chattel paper, choses in action, or similar property, Lender may demand, collect, receipt for, settle, compromise, adjust, sue for, foreclose, or realize on the Collateral as Lender may determine, whether or not Indebtedness or Collateral is then due.  For these purposes, Lender may, on behalf of and in the name of Grantor, receive, open and dispose of mail addressed to Grantor; change any address to which mail and payments are to be sent; and endorse notes, checks, drafts, money orders, documents of title, instruments and items pertaining to payment, shipment, or storage of any Collateral.  To facilitate collection, Lender may notify account debtors and obligors on any Collateral to make payments directly to Lender.

Obtain Deficiency.  If Lender chooses to sell any or all of the Collateral, Lender may obtain a judgment against Grantor for any deficiency remaining on the Indebtedness due to Lender after application of all amounts received from the exercise of the rights provided in this Agreement.  Grantor shall be liable for a deficiency even if the transaction described in this subsection is a sale of accounts or chattel paper. 

Other Rights and Remedies.  Lender shall have all the rights and remedies of a secured creditor under the provisions of the Uniform Commercial Code, as may be amended from time to time.  In addition, Lender shall have and may exercise any or all other rights and remedies it may have available at law, in equity, or otherwise.

Election of Remedies.  Except as may be prohibited by applicable law, all of Lender's rights and remedies, whether evidenced by this Agreement, the Related Documents, or by any other writing, shall be cumulative and may be exercised singularly or concurrently.  Election by Lender to pursue any remedy shall not exclude pursuit of any other remedy, and an election to make expenditures or to take action to perform an obligation of Grantor under this Agreement, after Grantor's failure to perform, shall not affect Lender's right to declare a default and exercise its remedies.

FINANCIAL CONTRACT. The words "Financial Contract" mean (1) an agreement (including terms and conditions incorporated by reference therein) which is a rate swap agreement, basis swap, forward rate agreement, commodity swap, commodity option, equity or equity index swap, bond option, interest rate option, foreign exchange agreement, rate cap agreement, rate floor agreement, rate collar agreement, currency swap agreement, cross-currency rate swap agreement, currency option, any other similar agreement (including any option to enter into any of the foregoing); or (2) any combination of the foregoing.

CHOICE OF VENUE. If there is a lawsuit, the undersigned, and if more than one, each of the undersigned, agree upon Lender's request to submit to the jurisdiction of the courts of Los Angeles County, State of California.

ORAL AGREEMENTS NOT EFFECTIVE. This Note or Agreement embodies the entire agreement and understanding between the parties hereto with respect to the subject matter hereof and supersedes all prior oral or written negotiations, agreements and understandings of the parties with respect to the subject matter hereof and shall remain in full force and effect in accordance with its terms and conditions.  Moreover, any subsequent oral statements, negotiations, agreements or understandings of the parties shall not be effective against Lender unless (i) expressly stated in writing, (ii) duly approved and authorized by an appropriate decision making committee of Lender on such terms and conditions as such committee shall deem necessary or appropriate in the committee’s sole and absolute opinion and judgment and (iii) executed by an authorized officer of Lender.  Borrower shall not rely or act on any oral statements, negotiations, agreements or understandings between the parties at anytime whatsoever, including before or during any Lender approval process stated above.  Borrower acknowledges and agrees that Borrower shall be responsible for its own actions, including any detrimental reliance on any oral statements, negotiations, agreements or understandings between the parties and that Lender shall not be liable for any possible claims, counterclaims, demands, actions, causes of action, damages, costs, expenses and liability whatsoever, known or unknown, anticipated or unanticipated, suspected or unsuspected, at law or in equity, originating in whole or in part in connection with any oral statements, negotiations, agreements or understandings between the parties which the Borrower may now or hereafter claim against the Lender.  Neither this Note or Agreement nor any other Related Document, nor any terms hereof or thereof may be amended, supplemented or modified except in accordance with the provisions of this section.  Lender may from time to time, (a) enter into with Borrower written amendments, supplements or modifications hereto and to the Related Documents or (b) waive, on such terms and conditions as Lender may specify in such instrument, any of the requirements of this Note or Agreement or the Related Documents or any Event Default and its consequences, if, but only if, such amendment, supplement, modification or waiver is (i) expressly stated in writing, (ii) duly approved and authorized by an appropriate decision making committee of Lender on such terms and conditions as such committee shall deem necessary or appropriate in the committee’s sole and absolute opinion and judgment and (iii) executed by an authorized officer of Lender.  Then such amendment, supplement, modification or waiver shall be effective only in the specific instance and specific purpose for which given.

JUDICIAL REFERENCE. If the waiver of the right to a trial by jury is not enforceable, the parties hereto agree that any and all disputes or controversies of any nature between them arising at any time shall be decided by a reference to a private judge, who shall be a retired state or federal court judge, mutually

selected by the parties or, if they cannot agree, then any party may seek to have a private judge appointed in accordance with California Code of Civil Procedure §§ 638 and 640 (or pursuant to comparable provisions of federal law if the dispute falls within the exclusive jurisdiction of the federal courts). The reference proceedings shall be conducted pursuant to and in accordance with the provisions of California Code of Civil Procedure §§ 638 through 645.1, inclusive. The private judge shall have the power, among others, to grant provisional relief, including without limitation, entering temporary restraining orders, issuing preliminary and permanent injunctions and appointing receivers.  All such proceedings shall be closed to the public and confidential and all records relating thereto shall be permanently sealed. If during the course of any dispute, a party desires to seek provisional relief, but a judge has not been appointed at that point pursuant to the judicial reference procedures, then such party may apply to the Court for such relief. The proceeding before the private judge shall be conducted in the same manner as it would be before a court under the rules of evidence applicable to judicial proceedings. The parties shall be entitled to discovery which shall be conducted in the same manner as it would be before a court under the rules of discovery applicable to judicial proceedings. The private judge shall oversee discovery and may enforce all discovery rules and orders applicable to judicial proceedings in the same manner as a trial court judge. The parties agree that the selected or appointed private judge shall have the power to decide all issues in the action or proceeding, whether of fact or of law, and shall report a statement of decision thereon pursuant to California Code of Civil Procedure § 644(a). Nothing in this paragraph shall limit the right of any party at any time to exercise self-help remedies, foreclose against collateral, or obtain provisional remedies. The private judge shall also determine all issues relating to the applicability, interpretation, and enforceability of this paragraph.

The parties agree that time is of the essence in conducting the referenced proceedings.  The parties shall promptly and diligently cooperate with one another and the referee, and shall perform such acts as may be necessary to obtain prompt and expeditious resolution of the dispute or controversy in accordance with the terms hereof.  The costs shall be borne equally by the parties.

CROSS-COLLATERALIZATION. In addition to the Note, this Agreement secures all obligations, debts and liabilities, plus interest thereon, of Grantor to Lender, or any one or more of them, as well as all claims by Lender against Grantor or any one or more of them, whether now existing or hereafter arising, whether related or unrelated to the purpose of the Note, including any Financial Contract whether voluntary or otherwise, whether due or not due, direct or indirect, determined or undetermined, absolute or contingent, liquidated or unliquidated, whether Grantor may be liable individually or jointly with others, whether obligated as guarantor, surety, accommodation party or otherwise, and whether recovery upon such amounts may be or hereafter may become barred by any statute of limitations, and whether the obligation to repay such amounts may be or hereafter may become otherwise unenforceable".

Preference Payments.  Any monies Lender pays because of an asserted preference claim in Grantor's bankruptcy will become a part of the Indebtedness and, at Lender's option, shall be payable by Grantor as provided in this Agreement.

No Waiver by Lender.  Lender shall not be deemed to have waived any rights under this Agreement 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 waiver by Lender of a provision of this Agreement shall not prejudice or constitute a waiver of Lender's right otherwise to demand strict compliance with that provision or any other provision of this Agreement.  No prior waiver by Lender, nor any course of dealing between Lender and Grantor, shall constitute a waiver of any of Lender's rights or of any of Grantor's obligations as to any future transactions.  Whenever the consent of Lender is required under this Agreement, 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 discretion of Lender.

Power of Attorney.  Grantor hereby appoints Lender as Grantor's irrevocable attorney-in-fact for the purpose of executing any documents necessary to perfect, amend, or to continue the security interest granted in this Agreement or to demand termination of filings of other secured parties.  Lender may at any time, and without further authorization from Grantor, file a carbon, photographic or other reproduction of any financing statement or of this Agreement for use as a financing statement.  Grantor will reimburse Lender for all expenses for the perfection and the continuation of the perfection of Lender's security interest in the Collateral.

Waiver of Co-Obligor's Rights.  If more than one person is obligated for the Indebtedness, Grantor irrevocably waives, disclaims and relinquishes all claims against such other person which Grantor has or would otherwise have by virtue of payment of the Indebtedness or any part thereof, specifically including but not limited to all rights of indemnity, contribution or exoneration.

Severability.  If a court of competent jurisdiction finds any provision of this Agreement to be illegal, invalid, or unenforceable as to any circumstance,

that finding shall not make the offending provision illegal, invalid, or unenforceable as to any other circumstance.  If feasible, the offending provision shall be considered modified so that it becomes legal, valid and enforceable.  If the offending provision cannot be so modified, it shall be considered deleted from this Agreement.  Unless otherwise required by law, the illegality, invalidity, or unenforceability of any provision of this Agreement shall not affect the legality, validity or enforceability of any other provision of this Agreement.

Survival of Representations and Warranties.  All representations, warranties, and agreements made by Grantor in this Agreement shall survive the execution and delivery of this Agreement, shall be continuing in nature, and shall remain in full force and effect until such time as Grantor's Indebtedness shall be paid in full.

Time is of the Essence.  Time is of the essence in the performance of this Agreement.

THIS DEED OF TRUST, INCLUDING THE ASSIGNMENT OF RENTS AND THE SECURITY INTEREST IN THE RENTS AND PERSONAL PROPERTY, IS GIVEN TO SECURE  (A)  PAYMENT OF THE INDEBTEDNESS AND  (B)  PERFORMANCE OF ANY AND ALL OBLIGATIONS OF THE TRUSTOR UNDER THE NOTE, THE RELATED DOCUMENTS, AND THIS DEED OF TRUST.  THIS DEED OF TRUST

IS GIVEN AND ACCEPTED ON THE FOLLOWING TERMS:

PAYMENT AND PERFORMANCE.  Except as otherwise provided in this Deed of Trust, Trustor shall pay to Lender all amounts secured by this Deed of Trust as they become due, and shall strictly and in a timely manner perform all of Trustor's obligations under the Note, this Deed of Trust, and the Related Documents.

POSSESSION AND MAINTENANCE OF THE PROPERTY.  Trustor agrees that Trustor's possession and use of the Property shall be governed by the following provisions:

Possession and Use.  Until the occurrence of an Event of Default, Trustor may  (1)  remain in possession and control of the Property;  (2)  use, operate or manage the Property; and  (3)  collect the Rents from the Property.

Duty to Maintain.  Trustor shall maintain the Property in tenantable condition and promptly perform all repairs, replacements, and maintenance necessary to preserve its value.

Compliance With Environmental Laws.  Trustor represents and warrants to Lender that:  (1)  During the period of Trustor's ownership of the Property, there has been no use, generation, manufacture, storage, treatment, disposal, release or threatened release of any Hazardous Substance by any person on, under, about or from the Property;  (2)  Trustor has no knowledge of, or reason to believe that there has been, except as previously disclosed to and acknowledged by Lender in writing,  (a)  any breach or violation of any Environmental Laws,  (b)  any use, generation, manufacture, storage, treatment, disposal, release or threatened release of any Hazardous Substance on, under, about or from the Property by any prior owners or occupants of the Property, or  (c)  any actual or threatened litigation or claims of any kind by any person relating to such matters; and  (3)  Except as previously disclosed to and acknowledged by Lender in writing,  (a)  neither Trustor nor any tenant, contractor, agent or other authorized user of the Property shall use, generate, manufacture, store, treat, dispose of or release any Hazardous Substance on, under, about or from the Property; and  (b)  any such activity shall be conducted in compliance with all applicable federal, state, and local laws, regulations and ordinances, including without limitation all Environmental Laws.  Trustor authorizes Lender and its agents to enter upon the Property to make such inspections and tests, at Trustor's expense, as Lender may deem appropriate to determine compliance of the Property with this section of the Deed of Trust.  Any inspections or tests made by Lender shall be for Lender's purposes only and shall not be construed to create any responsibility or liability on the part of Lender to Trustor or to any other person.  The representations and warranties contained herein are based on Trustor's due diligence in investigating the Property for Hazardous Substances.  Trustor hereby  (1)  releases and waives any future claims against Lender for indemnity or contribution in the event Trustor becomes liable for cleanup or other costs under any such laws; and  (2)  agrees to indemnify, defend, and hold harmless Lender against any and all claims, losses, liabilities, damages, penalties, and expenses which Lender may directly or indirectly sustain or suffer resulting from a breach of this section of the Deed of Trust or as a consequence of any use, generation, manufacture, storage, disposal, release or threatened release occurring prior to Trustor's ownership or interest in the Property, whether or not the same was or should have been known to Trustor.  The provisions of this section of the Deed of Trust, including the obligation to indemnify and defend, shall survive the payment of the Indebtedness and the satisfaction and reconveyance of the lien of this Deed of Trust and shall not be affected by Lender's acquisition of any interest in the Property, whether by foreclosure or otherwise.

Nuisance, Waste.  Trustor shall not cause, conduct or permit any nuisance nor commit, permit, or suffer any stripping of or waste on or to the Property or any portion of the Property.  Without limiting the generality of the foregoing, Trustor will not remove, or grant to any other party the right to remove, any timber, minerals (including oil and gas), coal, clay, scoria, soil, gravel or rock products without Lender's prior written consent.

Removal of Improvements.  Trustor shall not demolish or remove any Improvements from the Real Property without Lender's prior written consent.  As a condition to the removal of any Improvements, Lender may require Trustor to make arrangements satisfactory to Lender to replace such Improvements with Improvements of at least equal value.

Duty to Protect.  Trustor agrees neither to abandon or leave unattended the Property.  Trustor shall do all other acts, in addition to those acts set forth above in this section, which from the character and use of the Property are reasonably necessary to protect and preserve the Property.

DUE ON SALE - CONSENT BY LENDER.  Lender may, at Lender's option, declare immediately due and payable all sums secured by this Deed of Trust upon the sale or transfer, without Lender's prior written consent, of all or any part of the Real Property, or any interest in the Real Property.  A "sale or transfer" means the conveyance of Real Property or any right, title or interest in the Real Property; whether legal, beneficial or equitable; whether voluntary or involuntary; whether by outright sale, deed, installment sale contract, land contract, contract for deed, leasehold interest with a term greater than three (3) years, lease-option contract, or by sale, assignment, or transfer of any beneficial interest in or to any land trust holding title to the Real Property, or by any other method of conveyance of an interest in the Real Property.  If any Trustor is a corporation, partnership or limited liability company, transfer also includes any change in ownership of more than twenty-five percent (25%) of the voting stock, partnership interests or limited liability company interests, as the case may be, of such Trustor.  However, this option shall not be exercised by Lender if such exercise is prohibited by applicable law.

TAXES AND LIENS.  The following provisions relating to the taxes and liens on the Property are part of this Deed of Trust: 

Payment.  Trustor shall pay when due (and in all events at least ten (10) days prior to delinquency) all taxes, special taxes, assessments, charges (including water and sewer), fines and impositions levied against or on account of the Property, and shall pay when due all claims for work done on or for services rendered or material furnished to the Property.  Trustor shall maintain the Property free of all liens having priority

over or equal to the interest of Lender under this Deed of Trust, except for the lien of taxes and assessments not due and except as otherwise provided in this Deed of Trust.

Right to Contest.  Trustor may withhold payment of any tax, assessment, or claim in connection with a good faith dispute over the obligation to pay, so long as Lender's interest in the Property is not jeopardized.  If a lien arises or is filed as a result of nonpayment, Trustor shall within fifteen (15) days after the lien arises or, if a lien is filed, within fifteen (15) days after Trustor has notice of the filing, secure the discharge of the lien, or if requested by Lender, deposit with Lender cash or a sufficient corporate surety bond or other security satisfactory to Lender in an amount sufficient to discharge the lien plus any costs and attorneys' fees, or other charges that could accrue as a result of a foreclosure or sale under the lien.  In any contest, Trustor shall defend itself and Lender and shall satisfy any adverse judgment before enforcement against the Property.  Trustor shall name Lender as an additional obligee under any surety bond furnished in the contest proceedings.

Evidence of Payment.  Trustor shall upon demand furnish to Lender satisfactory evidence of payment of the taxes or assessments and shall authorize the appropriate governmental official to deliver to Lender at any time a written statement of the taxes and assessments against the Property.

Notice of Construction.  Trustor shall notify Lender at least fifteen (15) days before any work is commenced, any services are furnished, or any materials are supplied to the Property, if any mechanic's lien, materialmen's lien, or other lien could be asserted on account of the work, services, or materials and the cost exceeds $20,000.00.  Trustor will upon request of Lender furnish to Lender advance assurances satisfactory to Lender that Trustor can and will pay the cost of such improvements.

PROPERTY DAMAGE INSURANCE.  The following provisions relating to insuring the Property are a part of this Deed of Trust.

Maintenance of Insurance.  Trustor shall procure and maintain policies of fire insurance with standard extended coverage endorsements on a replacement basis for the full insurable value covering all Improvements on the Real Property in an amount sufficient to avoid application of any coinsurance clause, and with a standard mortgagee clause in favor of Lender.  Trustor shall also procure and maintain comprehensive general liability insurance in such coverage amounts as Lender may request with Trustee and Lender being named as additional insureds in such liability insurance policies.  Additionally, Trustor shall maintain such other insurance, including but not limited to hazard, business interruption, and boiler insurance, as Lender may reasonably require.  Notwithstanding the foregoing, in no event shall Trustor be required to provide hazard insurance in excess of the replacement value of the improvements on the Real Property.  Policies shall be written in form, amounts, coverages and basis reasonably acceptable to Lender and issued by a company or companies reasonably acceptable to Lender.  Trustor, upon request of Lender, will deliver to Lender from time to time the policies or certificates of insurance in form satisfactory to Lender, including stipulations that coverages will not be cancelled or diminished without at least thirty (30) days prior written notice to Lender.  Each insurance policy also shall include an endorsement providing that coverage in favor of Lender will not be impaired in any way by any act, omission or default of Trustor or any other person.  Should the Real Property be located in an area designated by the Administrator of the Federal Emergency Management Agency as a special flood hazard area, Trustor agrees to obtain and maintain Federal Flood Insurance, if available, within 45 days after notice is given by Lender that the Property is located in a special flood hazard area, for the full unpaid principal balance of the loan and any prior liens on the property securing the loan, up to the maximum policy limits set under the National Flood Insurance Program, or as otherwise required by Lender, and to maintain such insurance for the term of the loan.

Application of Proceeds.  Trustor shall promptly notify Lender of any loss or damage to the Property if the estimated cost of repair or replacement exceeds $25,000.00.  Lender may make proof of loss if Trustor fails to do so within fifteen (15) days of the casualty.  If in Lender's sole judgment Lender's security interest in the Property has been impaired, Lender may, at Lender's election, receive and retain the proceeds of any insurance and apply the proceeds to the reduction of the Indebtedness, payment of any lien affecting the Property, or the restoration and repair of the Property.  If the proceeds are to be applied to restoration and repair, Trustor shall repair or replace the damaged or destroyed Improvements in a manner satisfactory to Lender.  Lender shall, upon satisfactory proof of such expenditure, pay or reimburse Trustor from the proceeds for the reasonable cost of repair or restoration if Trustor is not in default under this Deed of Trust.  Any proceeds which have not been disbursed within 180 days after their receipt and which Lender has not committed to the repair or restoration of the Property shall be used first to pay any amount owing to Lender under this Deed of Trust, then to pay accrued interest, and the remainder, if any, shall be applied to the principal balance of the Indebtedness.  If Lender holds any proceeds after payment in full of the Indebtedness, such proceeds shall be paid to Trustor as Trustor's interests may appear.

Trustor's Report on Insurance.  Upon request of Lender, however not more than once a year, Trustor shall furnish to Lender a report on each existing policy of insurance showing:  (1)  the name of the insurer;  (2)  the risks insured;  (3)  the amount of the policy;  (4)  the property insured, the then current replacement value of such property, and the manner of determining that value; and  (5)  the expiration date of the policy.  Trustor shall, upon request of Lender, have an independent appraiser satisfactory to Lender determine the cash value replacement cost of the Property.

LENDER'S EXPENDITURES.  If any action or proceeding is commenced that would materially affect Lender's interest in the Property or if Trustor fails to comply with any provision of this Deed of Trust or any Related Documents, including but not limited to Trustor's failure to discharge or pay when due any amounts Trustor is required to discharge or pay under this Deed of Trust or any Related Documents, Lender on Trustor's behalf may (but shall not be obligated to) take any action that Lender deems appropriate, including but not limited to discharging or paying all taxes, liens, security interests, encumbrances and other claims, at any time levied or placed on the Property and paying all costs for insuring, maintaining and preserving the Property.  All such expenditures incurred or paid by Lender for such purposes will then bear interest at the rate charged under the Note from the date incurred or paid by Lender to the date of repayment by Trustor.  All such expenses will become a part of the Indebtedness and, at Lender's option, will  (A)  be payable on demand;  (B)  be added to the balance of the Note and be apportioned among and be payable with any installment payments to become due during either  (1)  the term of any applicable insurance policy; or  (2)  the remaining term of the Note; or  (C)  be treated as a balloon payment which will be due and payable at the Note's maturity.  The Deed of Trust also will secure payment of these amounts.  Such right shall be in addition to all other rights and remedies to which Lender may be entitled upon Default.

WARRANTY; DEFENSE OF TITLE.  The following provisions relating to ownership of the Property are a part of this Deed of Trust:

Title.  Trustor warrants that:  (a) Trustor holds good and marketable title of record to the Property in fee simple, free and clear of all liens and encumbrances other than those set forth in the Real Property description or in any title insurance policy, title report, or final title opinion issued in favor of, and accepted by, Lender in connection with this Deed of Trust, and  (b) Trustor has the full right, power, and authority to execute and deliver this Deed of Trust to Lender.

Defense of Title.  Subject to the exception in the paragraph above, Trustor warrants and will forever defend the title to the Property against the lawful claims of all persons.  In the event any action or proceeding is commenced that questions Trustor's title or the interest of Trustee or Lender under this Deed of Trust, Trustor shall defend the action at Trustor's expense.  Trustor may be the nominal party in such proceeding, but Lender shall be entitled to participate in the proceeding and to be represented in the proceeding by counsel of Lender's own choice, and Trustor will deliver, or cause to be delivered, to Lender such instruments as Lender may request from time to time to permit such participation.

Compliance With Laws.  Trustor warrants that the Property and Trustor's use of the Property complies with all existing applicable laws, ordinances, and regulations of governmental authorities.

Survival of Representations and Warranties.  All representations, warranties, and agreements made by Trustor in this Deed of Trust shall survive the execution and delivery of this Deed of Trust, shall be continuing in nature, and shall remain in full force and effect until such time as Trustor's Indebtedness shall be paid in full.

CONDEMNATION.  The following provisions relating to eminent domain and inverse condemnation proceedings are a part of this Deed of Trust:

Proceedings.  If any eminent domain or inverse condemnation proceeding is commenced affecting the Property, Trustor shall promptly notify Lender in writing, and Trustor shall promptly take such steps as may be necessary to pursue or defend the action and obtain the award.  Trustor may be the nominal party in any such proceeding, but Lender shall be entitled, at its election, to participate in the proceeding and to be represented in the proceeding by counsel of its own choice, and Trustor will deliver or cause to be delivered to Lender such instruments and documentation as may be requested by Lender from time to time to permit such participation.

Application of Net Proceeds.  If any award is made or settlement entered into in any condemnation proceedings affecting all or any part of the Property or by any proceeding or purchase in lieu of condemnation, Lender may at its election, and to the extent permitted by law, require that all or any portion of the award or settlement be applied to the Indebtedness and to the repayment of all reasonable costs, expenses, and attorneys' fees incurred by Trustee or Lender in connection with the condemnation proceedings.

Default on Other Payments.  Failure of Trustor within the time required by this Deed of Trust to make any payment for taxes or insurance, or any other payment necessary to prevent filing of or to effect discharge of any lien.

Default in Favor of Third Parties.  Should Grantor default under any loan, extension of credit, security agreement, purchase or sales agreement, or any other agreement, in favor of any other creditor or person that may materially affect any of Grantor's property or Grantor's ability to repay the Indebtedness or Grantor's ability to perform Grantor's obligations under this Deed of Trust or any of the Related Documents.

False Statements.  Any warranty, representation or statement made or furnished to Lender by Trustor or on Trustor's behalf under this Deed of Trust or the Related Documents is false or misleading in any material respect, either now or at the time made or furnished or becomes false or misleading at any time thereafter.

Defective Collateralization.  This Deed of Trust or any of the Related Documents ceases to be in full force and effect (including failure of any collateral document to create a valid and perfected security interest or lien) at any time and for any reason.

Adverse Change.  A material adverse change occurs in Trustor's financial condition, or Lender believes the prospect of payment or performance of the Indebtedness is impaired.

Right to Cure.  If any default, other than a default in payment, is curable and if Trustor has not been given a notice of a breach of the same provision of this Deed of Trust within the preceding twelve (12) months, it may be cured if Trustor, after Lender sends written notice to Trustor demanding cure of such default:  (1)  cures the default within fifteen (15) days; or  (2)  if the cure requires more than fifteen (15) days, immediately initiates steps which Lender deems in Lender's sole discretion to be sufficient to cure the default and thereafter continues and completes all reasonable and necessary steps sufficient to produce compliance as soon as reasonably practical.

Election of Remedies.  Election by Lender to pursue any remedy shall not exclude pursuit of any other remedy, and an election to make expenditures or to take action to perform an obligation of Trustor under this Deed of Trust, after Trustor's failure to perform, shall not affect Lender's right to declare a default and exercise its remedies.

Foreclosure by Sale.  Upon an Event of Default under this Deed of Trust, Beneficiary may declare the entire Indebtedness secured by this Deed of Trust immediately due and payable by delivery to Trustee of written declaration of default and demand for sale and of written notice of default and of election to cause to be sold the Property, which notice Trustee shall cause to be filed for record.  Beneficiary also shall deposit with Trustee this Deed of Trust, the Note, other documents requested by Trustee, and all documents evidencing expenditures secured hereby.  After the lapse of such time as may then be required by law following the recordation of the notice of default, and notice of sale having been given as then required by law, Trustee, without demand on Trustor, shall sell the Property at the time and place fixed by it in the notice of sale, either as a whole or in separate parcels, and in such order as it may determine, at public auction to the highest bidder for cash in lawful money of the United States, payable at time of sale.  Trustee may postpone sale of all or any portion of the Property by public announcement at such time and place of sale, and from time to time thereafter may postpone such sale by public announcement at the time fixed by the preceding postponement in accordance with applicable law.  Trustee shall deliver to such purchaser its deed conveying the Property so sold, but without any covenant or warranty, express or implied.  The recitals in such deed of any matters or facts shall be conclusive proof of the truthfulness thereof.  Any person, including Trustor, Trustee or Beneficiary may purchase at such sale.  After deducting all costs, fees and expenses of Trustee and of this Trust, including cost of evidence of title in connection with sale, Trustee shall apply the proceeds of sale to payment of:  all

sums expended under the terms hereof, not then repaid, with accrued interest at the amount allowed by law in effect at the date hereof; all other sums then secured hereby; and the remainder, if any, to the person or persons legally entitled thereto.

Judicial Foreclosure.  With respect to all or any part of the Real Property, Lender shall have the right in lieu of foreclosure by power of sale to foreclose by judicial foreclosure in accordance with and to the full extent provided by California law.

UCC Remedies.  With respect to all or any part of the Personal Property, Lender shall have all the rights and remedies of a secured party under the Uniform Commercial Code, including without limitation the right to recover any deficiency in the manner and to the full extent provided by California law.

Collect Rents.  Lender shall have the right, without notice to Trustor to take possession of and manage the Property and collect the Rents, including amounts past due and unpaid, and apply the net proceeds, over and above Lender's costs, against the Indebtedness.  In furtherance of this right, Lender may require any tenant or other user of the Property to make payments of rent or use fees directly to Lender.  If the Rents are collected by Lender, then Trustor irrevocably designates Lender as Trustor's attorney-in-fact to endorse instruments received in payment thereof in the name of Trustor and to negotiate the same and collect the proceeds.  Payments by tenants or other users to Lender in response to Lender's demand shall satisfy the obligations for which the payments are made, whether or not any proper grounds for the demand existed.  Lender may exercise its rights under this subparagraph either in person, by agent, or through a receiver.

Appoint Receiver.  Lender shall have the right to have a receiver appointed to take possession of all or any part of the Property, with the power to protect and preserve the Property, to operate the Property preceding foreclosure or sale, and to collect the Rents from the Property and apply the proceeds, over and above the cost of the receivership, against the Indebtedness.  The receiver may serve without bond if permitted by law.  Lender's right to the appointment of a receiver shall exist whether or not the apparent value of the Property exceeds the Indebtedness by a substantial amount.  Employment by Lender shall not disqualify a person from serving as a receiver.

Tenancy at Sufferance.  If Trustor remains in possession of the Property after the Property is sold as provided above or Lender otherwise becomes entitled to possession of the Property upon default of Trustor, Trustor shall become a tenant at sufferance of Lender or the purchaser of the Property and shall, at Lender's option, either  (1)  pay a reasonable rental for the use of the Property, or  (2)  vacate the Property immediately upon the demand of Lender. 

Other Remedies.  Trustee or Lender shall have any other right or remedy provided in this Deed of Trust or the Note or available at law or in equity.

Notice of Sale.  Lender shall give Trustor reasonable notice of the time and place of any public sale of the Personal Property or of the time after which any private sale or other intended disposition of the Personal Property is to be made.  Reasonable notice shall mean notice given at least ten (10) days before the time of the sale or disposition.  Any sale of the Personal Property may be made in conjunction with any sale of the Real Property.

Sale of the Property.  To the extent permitted by applicable law, Trustor hereby waives any and all rights to have the Property marshalled.  In exercising its rights and remedies, the Trustee or Lender shall be free to sell all or any part of the Property together or separately, in one sale or by separate sales.  Lender shall be entitled to bid at any public sale on all or any portion of the Property.

Attorneys' Fees; Expenses.  If Lender institutes any suit or action to enforce any of the terms of this Deed of Trust, Lender shall be entitled to recover such sum as the court may adjudge reasonable as attorneys' fees at trial and upon any appeal.  Whether or not any court action is involved, and to the extent not prohibited by law, all reasonable expenses Lender incurs that in Lender's opinion are necessary at any time for the protection of its interest or the enforcement of its rights shall become a part of the Indebtedness payable on demand and shall bear interest at the Note rate from the date of the expenditure until repaid.  Expenses covered by this paragraph include, without limitation, however subject to any limits under applicable law, Lender's attorneys' fees and Lender's legal expenses, whether or not there is a lawsuit, including attorneys' fees and expenses for bankruptcy proceedings (including efforts to modify or vacate any automatic stay or injunction), appeals, and any anticipated post-judgment collection services, the cost of searching records, obtaining title reports (including foreclosure reports), surveyors' reports, and appraisal fees, title insurance, and fees for the Trustee, to the extent permitted by applicable law.  Trustor also will pay any court costs, in addition to all other sums provided by law.

Rights of Trustee.  Trustee shall have all of the rights and duties of Lender as set forth in this section.

ORAL AGREEMENTS NOT EFFECTIVE. This Note or Agreement embodies the entire agreement and understanding between the parties hereto with respect to the subject matter hereof and supersedes all prior oral or written negotiations, agreements and understandings of the parties with respect to the subject matter hereof and shall remain in full force and effect in accordance with its terms and conditions.  Moreover, any subsequent oral statements, negotiations, agreements or understandings of the parties shall not be effective against Lender unless (i) expressly stated in writing, (ii) duly approved and authorized by an appropriate decision making committee of Lender on such terms and conditions as such committee shall deem necessary or appropriate in the committee’s sole and absolute opinion and judgment and (iii) executed by an authorized officer of Lender.  Borrower shall not rely or act on any oral statements, negotiations, agreements or understandings between the parties at anytime whatsoever, including before or during any Lender approval process stated above.  Borrower acknowledges and agrees that Borrower shall be responsible for its own actions, including any detrimental reliance on any oral statements, negotiations, agreements or understandings between the parties and that Lender shall not be liable for any possible claims, counterclaims, demands, actions, causes of action, damages, costs, expenses and liability whatsoever, known or unknown, anticipated or unanticipated, suspected or unsuspected, at law or in equity, originating in whole or in part in connection with any oral statements, negotiations, agreements or understandings between the parties which the Borrower may now or hereafter claim against the Lender.  Neither this Note or Agreement nor any other Related Document, nor any terms hereof or thereof may be amended, supplemented or modified except in accordance with the provisions of this section.  Lender may from time to time, (a) enter into with Borrower written amendments, supplements or modifications hereto and to the Related Documents or (b) waive, on such terms and conditions as Lender may specify in such instrument, any of the requirements of this Note or Agreement or the Related Documents or any Event Default and its consequences, if, but only if, such amendment, supplement, modification or waiver is (i) expressly stated in writing, (ii) duly approved and authorized by an appropriate decision making committee of Lender on such terms and conditions as such committee shall deem necessary or appropriate in the committee’s sole and absolute opinion and judgment and (iii) executed by an authorized officer of Lender.  Then such amendment, supplement, modification or waiver shall be effective only in the specific instance and specific purpose for which given.

JUDICIAL REFERENCE. If the waiver of the right to a trial by jury is not enforceable, the parties hereto agree that any and all disputes or controversies of any nature between them arising at any time shall be decided by a reference to a private judge, who shall be a retired state or federal court judge, mutually selected by the parties or, if they cannot agree, then any party may seek to have a private judge appointed in accordance with California Code of Civil Procedure §§ 638 and 640 (or pursuant to comparable provisions of federal law if the dispute falls within the exclusive jurisdiction of the federal courts).

The private judge shall have the power, among others, to grant provisional relief, including without limitation, entering temporary restraining orders, issuing preliminary and permanent injunctions and appointing receivers.  All such proceedings shall be closed to the public and confidential and all records relating thereto shall be permanently sealed. If during the course of any dispute, a party desires to seek provisional relief, but a judge has not been appointed at that point pursuant to the judicial reference procedures, then such party may apply to the Court for such relief. The proceeding before the private judge shall be conducted in the same manner as it would be before a court under the rules of evidence applicable to judicial proceedings. The parties shall be entitled to discovery which shall be conducted in the same manner as it would be before a court under the rules of discovery applicable to judicial proceedings. The private judge shall oversee discovery and may enforce all discovery rules and orders applicable to judicial proceedings in the same manner as a trial court judge. The parties agree that the selected or appointed private judge shall have the power to decide all issues in the action or proceeding, whether of fact or of law, and shall report a statement of decision thereon pursuant to California Code of Civil Procedure § 644(a). Nothing in this paragraph shall limit the right of any party at any time to exercise self-help remedies, foreclose against collateral, or obtain provisional remedies. The private judge shall also determine all issues relating to the applicability, interpretation, and enforceability of this paragraph.

The parties agree that time is of the essence in conducting the referenced proceedings.  The parties shall promptly and diligently cooperate with one another and the referee, and shall perform such acts as may be necessary to obtain prompt and expeditious resolution of the dispute or controversy in accordance with the terms hereof.  The costs shall be borne equally by the parties.

No Requirement to Act.  Lender shall not be required to do any of the foregoing acts or things, and the fact that Lender shall have performed one or more of the foregoing acts or things shall not require Lender to do any other specific act or thing.

APPLICATION OF RENTS.  All costs and expenses incurred by Lender in connection with the Property shall be for Grantor's account and Lender may pay such costs and expenses from the Rents.  Lender, in its sole discretion, shall determine the application of any and all Rents received by it; however, any such Rents received by Lender which are not applied to such costs and expenses shall be applied to the Indebtedness.  All expenditures made by Lender under this Assignment and not reimbursed from the Rents shall become a part of the Indebtedness secured by this Assignment, and shall be payable on demand, with interest at the Note rate from date of expenditure until paid.

FULL PERFORMANCE.  If Grantor pays all of the Indebtedness when due and otherwise performs all the obligations imposed upon Grantor under this Assignment, the Note, and the Related Documents, Lender shall execute and deliver to Grantor a suitable satisfaction of this Assignment and suitable statements of termination of any financing statement on file evidencing Lender's security interest in the Rents and the Property.  Any termination fee required by law shall be paid by Grantor, if permitted by applicable law.

LENDER'S EXPENDITURES.  If any action or proceeding is commenced that would materially affect Lender's interest in the Property or if Grantor fails to comply with any provision of this Assignment or any Related Documents, including but not limited to Grantor's failure to discharge or pay when due any amounts Grantor is required to discharge or pay under this Assignment or any Related Documents, Lender on Grantor's behalf may (but shall not be obligated to) take any action that Lender deems appropriate, including but not limited to discharging or paying all taxes, liens, security interests, encumbrances and other claims, at any time levied or placed on the Rents or the Property and paying all costs for insuring, maintaining and preserving the Property.  All such expenditures incurred or paid by Lender for such purposes will then bear interest at the rate charged under the Note from the date incurred or paid by Lender to the date of repayment by Grantor.  All such expenses will become a part of the Indebtedness and, at Lender's option, will  (A)  be payable on demand;  (B)  be added to the balance of the Note and be apportioned among and be payable with any installment payments to become due during either  (1)  the term of any applicable insurance policy; or  (2)  the remaining term of the Note; or  (C)  be treated as a balloon payment which will be due and payable at the Note's maturity.  The Assignment also will secure payment of these amounts.  Such right shall be in addition to all other rights and remedies to which Lender may be entitled upon Default.

DEFAULT.  Each of the following, at Lender's option, shall constitute an Event of Default under this Assignment:

Payment Default.  Grantor fails to make any payment when due under the Indebtedness.

Other Defaults.  Grantor fails to comply with or to perform any other term, obligation, covenant or condition contained in this Assignment or in any of the Related Documents or to comply with or to perform any term, obligation, covenant or condition contained in any other agreement between Lender and Grantor.

Default on Other Payments.  Failure of Grantor within the time required by this Assignment to make any payment for taxes or insurance, or any other payment necessary to prevent filing of or to effect discharge of any lien.

Default in Favor of Third Parties.  Grantor defaults under any loan, extension of credit, security agreement, purchase or sales agreement, or any other agreement, in favor of any other creditor or person that may materially affect any of Grantor's property or ability to perform Grantor's obligations under this Assignment or any of the Related Documents.

False Statements.  Any warranty, representation or statement made or furnished to Lender by Grantor or on Grantor's behalf under this Assignment or the Related Documents is false or misleading in any material respect, either now or at the time made or furnished or becomes false or misleading at any time thereafter.

Defective Collateralization.  This Assignment or any of the Related Documents ceases to be in full force and effect (including failure of any collateral document to create a valid and perfected security interest or lien) at any time and for any reason.

Insolvency.  The dissolution or termination of Grantor's existence as a going business, the insolvency of Grantor, the appointment of a receiver for any part of Grantor's property, any assignment for the benefit of creditors, any type of creditor workout, or the commencement of any proceeding under any bankruptcy or insolvency laws by or against Grantor.

Creditor or Forfeiture Proceedings.  Commencement of foreclosure or forfeiture proceedings, whether by judicial proceeding, self-help, repossession or any other method, by any creditor of Grantor or by any governmental agency against the Rents or any property securing the Indebtedness.  This includes a garnishment of any of Grantor's accounts, including deposit accounts, with Lender.  However, this Event of Default shall not apply if there is a good faith dispute by Grantor as to the validity or reasonableness of the claim which is the basis of the creditor or forfeiture proceeding and if Grantor gives Lender written notice of the creditor or forfeiture proceeding and deposits with Lender monies or a surety bond for the creditor or forfeiture proceeding, in an amount determined by Lender, in its sole discretion, as being an adequate reserve or bond for the dispute.

Property Damage or Loss.  The Property is lost, stolen, substantially damaged, sold, or borrowed against.

Events Affecting Guarantor.  Any of the preceding events occurs with respect to any guarantor, endorser, surety, or accommodation party of any of the Indebtedness or any guarantor, endorser, surety, or accommodation party dies or becomes incompetent, or revokes or disputes the validity of, or liability under, any Guaranty of the Indebtedness.

Adverse Change.  A material adverse change occurs in Grantor's financial condition, or Lender believes the prospect of payment or performance of the Indebtedness is impaired.

Cure Provisions.  If any default, other than a default in payment, is curable and if Grantor has not been given a notice of a breach of the same provision of this Assignment within the preceding twelve (12) months, it may be cured if Grantor, after Lender sends written notice to Grantor demanding cure of such default:  (1)  cures the default within fifteen (15) days; or  (2)  if the cure requires more than fifteen (15) days, immediately initiates steps which Lender deems in Lender's sole discretion to be sufficient to cure the default and thereafter continues and completes all reasonable and necessary steps sufficient to produce compliance as soon as reasonably practical.

RIGHTS AND REMEDIES ON DEFAULT.  Upon the occurrence of any Event of Default and at any time thereafter, Lender may exercise any one or more of the following rights and remedies, in addition to any other rights or remedies provided by law:

Accelerate Indebtedness.  Lender shall have the right at its option without notice to Grantor to declare the entire Indebtedness immediately due and payable, including any prepayment fee that Grantor would be required to pay.

Collect Rents.  Lender shall have the right, without notice to Grantor, to take possession of the Property and collect the Rents, including amounts past due and unpaid, and apply the net proceeds, over and above Lender's costs, against the Indebtedness.  In furtherance of this right, Lender shall have all the rights provided for in the Lender's Right to Receive and Collect Rents Section, above.  If the Rents are collected by Lender, then Grantor irrevocably designates Lender as Grantor's attorney-in-fact to endorse instruments received in payment thereof in the name of Grantor and to negotiate the same and collect the proceeds.  Payments by tenants or other users to Lender in response to Lender's demand shall satisfy the obligations for which the payments are made, whether or not any proper grounds for the demand existed.  Lender may exercise its rights under this subparagraph either in person, by agent, or through a receiver.

Appoint Receiver.  Lender shall have the right to have a receiver appointed to take possession of all or any part of the Property, with the power to protect and preserve the Property, to operate the Property preceding foreclosure or sale, and to collect the Rents from the Property and apply the proceeds, over and above the cost of the receivership, against the Indebtedness.  The receiver may serve without bond if permitted by law.  Lender's right to the appointment of a receiver shall exist whether or not the apparent value of the Property exceeds the Indebtedness by a substantial amount.  Employment by Lender shall not disqualify a person from serving as a receiver.

Other Remedies.  Lender shall have all other rights and remedies provided in this Assignment or the Note or by law.

Election of Remedies.  Election by Lender to pursue any remedy shall not exclude pursuit of any other remedy, and an election to make expenditures or to take action to perform an obligation of Grantor under this Assignment, after Grantor's failure to perform, shall not affect Lender's right to declare a default and exercise its remedies.

Attorneys' Fees; Expenses.  If Lender institutes any suit or action to enforce any of the terms of this Assignment, Lender shall be entitled to recover such sum as the court may adjudge reasonable as attorneys' fees at trial and upon any appeal.  Whether or not any court action is involved, and to the extent not prohibited by law, all reasonable expenses Lender incurs that in Lender's opinion are necessary at any time for the protection of its interest or the enforcement of its rights shall become a part of the Indebtedness payable on demand and shall bear interest at the Note rate from the date of the expenditure until repaid.  Expenses covered by this paragraph include, without limitation, however subject to any limits under applicable law, Lender's attorneys' fees and Lender's legal expenses, whether or not there is a lawsuit, including attorneys' fees and expenses for bankruptcy proceedings (including efforts to modify or vacate any automatic stay or injunction), appeals, and any anticipated post-judgment collection services, the cost of searching records, obtaining title reports (including foreclosure reports), surveyors' reports, and appraisal fees, title insurance, and fees for the Trustee, to the extent permitted by applicable law.  Grantor also will pay any court costs, in addition to all other sums provided by law.

CHOICE OF VENUE. If there is a lawsuit, the undersigned, and if more than one, each of the undersigned, agree upon Lender's request to submit to the jurisdiction of the courts of Los Angeles County, State of California.

ORAL AGREEMENTS NOT EFFECTIVE. This Note or Agreement embodies the entire agreement and understanding between the parties hereto

with respect to the subject matter hereof and supersedes all prior oral or written negotiations, agreements and understandings of the parties with respect to the subject matter hereof and shall remain in full force and effect in accordance with its terms and conditions.  Moreover, any subsequent oral statements, negotiations, agreements or understandings of the parties shall not be effective against Lender unless (i) expressly stated in writing, (ii) duly approved and authorized by an appropriate decision making committee of Lender on such terms and conditions as such committee shall deem necessary or appropriate in the committee’s sole and absolute opinion and judgment and (iii) executed by an authorized officer of Lender.  Borrower shall not rely or act on any oral statements, negotiations, agreements or understandings between the parties at anytime whatsoever, including before or during any Lender approval process stated above.  Borrower acknowledges and agrees that Borrower shall be responsible for its own actions, including any detrimental reliance on any oral statements, negotiations, agreements or understandings between the parties and that Lender shall not be liable for any possible claims, counterclaims, demands, actions, causes of action, damages, costs, expenses and liability whatsoever, known or unknown, anticipated or unanticipated, suspected or unsuspected, at law or in equity, originating in whole or in part in connection with any oral statements, negotiations, agreements or understandings between the parties which the Borrower may now or hereafter claim against the Lender.  Neither this Note or Agreement nor any other Related Document, nor any terms hereof or thereof may be amended, supplemented or modified except in accordance with the provisions of this section.  Lender may from time to time, (a) enter into with Borrower written amendments, supplements or modifications hereto and to the Related Documents or (b) waive, on such terms and conditions as Lender may specify in such instrument, any of the requirements of this Note or Agreement or the Related Documents or any Event Default and its consequences, if, but only if, such amendment, supplement, modification or waiver is (i) expressly stated in writing, (ii) duly approved and authorized by an appropriate decision making committee of Lender on such terms and conditions as such committee shall deem necessary or appropriate in the committee’s sole and absolute opinion and judgment and (iii) executed by an authorized officer of Lender.  Then such amendment, supplement, modification or waiver shall be effective only in the specific instance and specific purpose for which given.

JUDICIAL REFERENCE. If the waiver of the right to a trial by jury is not enforceable, the parties hereto agree that any and all disputes or controversies of any nature between them arising at any time shall be decided by a reference to a private judge, who shall be a retired state or federal court judge, mutually selected by the parties or, if they cannot agree, then any party may seek to have a private judge appointed in accordance with California Code of Civil Procedure §§ 638 and 640 (or pursuant to comparable provisions of federal law if the dispute falls within the exclusive jurisdiction of the federal courts). The reference proceedings shall be conducted pursuant to and in accordance with the provisions of California Code of Civil Procedure §§ 638 through 645.1, inclusive. The private judge shall have the power, among others, to grant provisional relief, including without limitation, entering temporary restraining orders, issuing preliminary and permanent injunctions and appointing receivers.  All such proceedings shall be closed to the public and confidential and all records relating thereto shall be permanently sealed. If during the course of any dispute, a party desires to seek provisional relief, but a judge has not been appointed at that point pursuant to the judicial reference procedures, then such party may apply to the Court for such relief. The proceeding before the private judge shall be conducted in the same manner as it would be before a court under the rules of evidence applicable to judicial proceedings. The parties shall be entitled to discovery which shall be conducted in the same manner as it would be before a court under the rules of discovery applicable to judicial proceedings. The private judge shall oversee discovery and may enforce all discovery rules and orders applicable to judicial proceedings in the same manner as a trial court judge. The parties agree that the selected or appointed private judge shall have the power to decide all issues in the action or proceeding, whether of fact or of law, and shall report a statement of decision thereon pursuant to California Code of Civil Procedure § 644(a). Nothing in this paragraph shall limit the right of any party at any time to exercise self-help remedies, foreclose against collateral, or obtain provisional remedies. The private judge shall also determine all issues relating to the applicability, interpretation, and enforceability of this paragraph.

The parties agree that time is of the essence in conducting the referenced proceedings.  The parties shall promptly and diligently cooperate with one another and the referee, and shall perform such acts as may be necessary to obtain prompt and expeditious resolution of the dispute or controversy in accordance with the terms hereof.  The costs shall be borne equally by the parties.

AGREEMENT TO PROVIDE INSURANCE

INSURANCE REQUIREMENTS.  Grantor, Amphastar Pharmaceuticals, Inc. ("Grantor"), understands that insurance coverage is required in connection with the extending of a loan or the providing of other financial accommodations to Grantor by Lender.  These requirements are set forth in the security documents for the loan.  The following minimum insurance coverages must be provided on the following described collateral (the "Collateral"): 

Type:  Fire and extended coverage.

Amount:  Full Insurable Value; however in no event greater than the value of the replacement cost of the improvements.

Latest Delivery Date:  By the loan closing date.

INSURANCE COMPANY.  Grantor may obtain insurance from any insurance company Grantor may choose that is reasonably acceptable to Lender.  Grantor understands that credit may not be denied solely because insurance was not purchased through Lender.

FLOOD INSURANCE.  Flood Insurance for the Collateral securing this loan is described as follows: 

Real Estate at 13760 Magnolia Avenue, Chino, CA  91710; 13770 Magnolia Avenue, Chino, CA 91710 and 11525 6th Street, Rancho Cucamonga, CA  91730.

 The Collateral securing this loan is not currently located in an area identified as having special flood hazards.  Therefore, no special flood hazard insurance is necessary at this time.  Should the Collateral at any time be deemed to be located in an area designated by the Administrator of the Federal Emergency Management Agency as a special flood hazard area, Grantor agrees to obtain and maintain Federal Flood Insurance, if available, within 45 days after notice is given by Lender that the Collateral is located in a special flood hazard area, for the full unpaid principal balance of the loan and any prior liens on the property securing the loan, up to the maximum policy limits set under the National Flood Insurance Program, or as otherwise required by Lender, and to maintain such insurance for the term of the loan.  Flood insurance may be purchased under the National Flood Insurance Program or from private insurers.

FAILURE TO PROVIDE INSURANCE.  Grantor agrees to deliver to Lender, on the latest delivery date stated above, evidence of the required insurance as provided above, with an effective date of May 18, 2017, or earlier.  Grantor acknowledges and agrees that if Grantor fails to provide any required insurance or fails to continue such insurance in force, Lender may do so at Grantor's expense as provided in the applicable security document.  The cost of any such insurance, at the option of Lender, shall be added to the indebtedness as provided in the security document.  GRANTOR ACKNOWLEDGES THAT IF LENDER SO PURCHASES ANY SUCH INSURANCE, THE INSURANCE WILL PROVIDE LIMITED PROTECTION AGAINST PHYSICAL DAMAGE TO THE COLLATERAL, UP TO AN AMOUNT EQUAL TO THE LESSER OF (1) THE UNPAID BALANCE OF THE DEBT, EXCLUDING ANY UNEARNED FINANCE CHARGES, OR (2) THE VALUE OF THE COLLATERAL; HOWEVER, GRANTOR'S EQUITY IN THE COLLATERAL MAY NOT BE INSURED.  IN ADDITION, THE INSURANCE MAY NOT PROVIDE ANY PUBLIC LIABILITY OR PROPERTY DAMAGE INDEMNIFICATION AND MAY NOT MEET THE REQUIREMENTS OF ANY FINANCIAL RESPONSIBILITY LAWS.

AUTHORIZATION.  For purposes of insurance coverage on the Collateral, Grantor authorizes Lender to provide to any person (including any insurance agent or company) all information Lender deems appropriate, whether regarding the Collateral, the loan or other financial accommodations, or both. 

GRANTOR ACKNOWLEDGES HAVING READ ALL THE PROVISIONS OF THIS AGREEMENT TO PROVIDE INSURANCE AND AGREES TO ITS TERMS.  THIS AGREEMENT IS DATED MAY 18, 2017.
