shall promptly notify Secured Party of (i) any change in the name of Debtor, (ii) any change in the state of its incorporation, organization or
registration, (iii) any relocation of its chief executive offices, (iv) any relocation of any of the Collateral, (v) any of the Collateral being lost, stolen, missing, destroyed,
materially damaged or worn out, or (vi) any lien, claim or encumbrance other than Permitted Liens attaching to or being made against any of the Collateral. 

        (b)   Debtor
will deliver to Secured Party financial statements as follows. If Debtor is a privately held company, then Debtor agrees to provide monthly financial statements,
certified by Debtor's president or chief financial officer including a balance sheet, statement of operations and cash flow statement within 30 days of each month end and its complete audited
annual financial statements, certified by a recognized firm of certified public accountants, within 120 days of fiscal year end or at such time as Debtor's Board of Directors receives the
audit. If Debtor is a publicly held company, then Debtor agrees to provide quarterly unaudited statements and annual audited statements, certified by a recognized firm of certified public accountants,
within 10 days after the statements are provided to the Securities and Exchange Commission ("SEC"). All such statements are to be prepared using generally accepted accounting principles
("GAAP") and, if Debtor is a publicly held company, are to be in compliance with SEC requirements. So long as Debtor is filing GAAP financial statements with the 

SEC
as part of its initial public offering, it shall be deemed to be a publicly held company for purposes hereof. 

6.     FURTHER ASSURANCES.  

        (a)   Debtor
shall, upon request of Secured Party, furnish to Secured Party such further information, execute and deliver to Secured Party such documents and instruments
(including, without limitation, Uniform Commercial Code financing statements) and shall do such other acts and things as Secured Party may at any time reasonably request relating to the perfection or
protection of the security interest created by this Agreement or for the purpose of carrying out the intent of this Agreement. Without limiting the foregoing, Debtor shall cooperate and do all acts
deemed necessary or advisable by Secured Party to continue in Secured Party a perfected first security interest in the Collateral, and shall obtain and furnish to Secured Party any subordinations,
releases, landlord waivers, lessor waivers, mortgagee waivers, or control agreements, and similar documents as may be from time to time requested by, and in form and substance satisfactory to, Secured
Party. 

        (b)   Debtor
authorizes Secured Party to file a financing statement and amendments thereto describing the Collateral and containing any other information required by
the applicable Uniform Commercial Code. Debtor irrevocably grants to Secured Party the power to sign Debtor's name and generally to act on behalf of Debtor to execute and file applications for title,
transfers of title, financing statements, notices of lien and other documents pertaining to any or all of the Collateral; this power is coupled with Secured Party's interest in the Collateral. Debtor
shall, if any certificate of title be required or permitted by law for any of the Collateral, obtain and promptly deliver to Secured Party such certificate showing the lien of this Agreement with
respect to the Collateral. Debtor ratifies its prior authorization for Secured Party to file financing statements and amendments thereto describing the Collateral and containing any other information
required by the Uniform Commercial Code if filed prior to the date hereof. 

        (c)   Debtor
shall indemnify and defend the Secured Party, its successors and assigns, and their respective directors, officers and employees, from and against all claims,
actions and suits (including, without limitation, related attorneys' fees) of any kind whatsoever arising, directly or indirectly, in connection with any of the Collateral.

	(vi)
	Any

proceeding is commenced against Debtor or any of the Collateral, which in the good faith judgment of Secured Party subjects any of the Collateral to a material risk of attachment, execution, 

levy,
seizure or confiscation and no bond is posted or protective order obtained to negate such risk; 

	(vii)
	Debtor
breaches or is in default under any other agreement between Debtor and Secured Party;

	(viii)
	Debtor
or any guarantor or other obligor for any of the Indebtedness (collectively "Guarantor") dissolves, terminates

	(xv)
	Debtor
defaults under any other material obligation for (A) borrowed money, (B) the deferred purchase price of property or (C) payments due under

of Debtor or all or substantially all of Debtor's assets, in either case, without Secured Party's prior written consent. 

        (b)   If
Debtor is in default, the Secured Party, at its option, may declare any or all of the Indebtedness (including the outstanding principal balance plus any accrued
default interest and late charges through the date the default is cured) to be immediately due and payable, without demand or notice to Debtor or any Guarantor. The accelerated obligations and
liabilities shall bear interest (both before and after any judgment) until paid in full at the lower of eighteen percent (18%) per annum or the maximum rate not prohibited by applicable law. 

        (c)   After
default, Secured Party shall have all of the rights and remedies of a Secured Party under the Uniform Commercial Code, and under any other applicable law. Without

of the Collateral, applying proceeds from such disposition to the obligations then in default. If requested by Secured Party, Debtor shall promptly assemble the Collateral and make it available to
Secured Party at a place to be designated by Secured Party which is reasonably convenient to both parties. Secured Party may also render any or all of the Collateral unusable at the Debtor's premises
and may dispose of such Collateral on such premises without liability for rent or costs. Any notice that Secured Party is required to give to Debtor under the Uniform Commercial Code of the time and
place of any public sale or the time after which any private sale or other intended disposition of the Collateral is to be made shall be deemed to constitute reasonable 

notice
if such notice is given to the last known address of Debtor at least five (5) days prior to such action. 

        (d)   Proceeds
from any sale or lease or other disposition shall be applied: first, to all costs of repossession, storage, and disposition including without limitation
attorneys', appraisers', and auctioneers' fees; second, to discharge the obligations then in default; third, to discharge any other Indebtedness of Debtor to Secured Party, whether as obligor,
endorser, guarantor, surety or indemnitor; fourth, to expenses incurred in paying or settling liens and claims against the Collateral; and lastly, to Debtor, if there exists any surplus. Debtor shall
remain fully liable for any deficiency. 

        (e)   Debtor
agrees to pay all reasonable attorneys' fees and other costs incurred by Secured Party in connection with the enforcement, assertion, defense or preservation of
Secured Party's rights and remedies under this Agreement, or if prohibited by law, such lesser sum as may be permitted. Debtor further agrees that such fees and costs shall constitute Indebtedness. 

        (f)    Secured
Party's rights and remedies under this Agreement or otherwise arising are cumulative and may be exercised singularly or concurrently. Neither the failure nor any
delay on the part of the Secured Party to exercise any right, power or privilege under this Agreement shall operate as a waiver, nor shall any single or partial exercise of any right, power or
privilege preclude any other or further exercise of that or any other right, power or privilege. SECURED PARTY SHALL NOT BE DEEMED TO HAVE WAIVED ANY OF ITS RIGHTS UNDER THIS AGREEMENT OR UNDER ANY
OTHER AGREEMENT, INSTRUMENT OR PAPER SIGNED BY DEBTOR UNLESS SUCH WAIVER IS EXPRESSED IN WRITING AND SIGNED BY SECURED PARTY. A waiver on any one occasion shall not be construed as a bar to or waiver
of any right or remedy on any future occasion. 

        (g)   DEBTOR
AND SECURED PARTY UNCONDITIONALLY WAIVE THEIR RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT, ANY OF THE OTHER
DEBT DOCUMENTS, ANY OF THE INDEBTEDNESS SECURED HEREBY, ANY DEALINGS BETWEEN DEBTOR AND SECURED PARTY RELATING TO THE SUBJECT MATTER OF THIS TRANSACTION OR ANY RELATED TRANSACTIONS, AND/OR THE
RELATIONSHIP THAT IS BEING ESTABLISHED BETWEEN DEBTOR AND SECURED PARTY. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL ENCOMPASSING OF ANY AND ALL DISPUTES THAT MAY BE FILED IN ANY COURT. THIS WAIVER
IS IRREVOCABLE. THIS WAIVER MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING. THE WAIVER ALSO SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT, ANY
OTHER DEBT DOCUMENTS, OR TO ANY OTHER DOCUMENTS OR AGREEMENTS RELATING TO THIS TRANSACTION OR ANY RELATED TRANSACTION. THIS AGREEMENT MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE COURT. 

8.     MISCELLANEOUS.  

        (a)   This
Agreement, any Note and/or any of the other Debt Documents may be assigned, in whole or in part, by Secured Party without notice to Debtor, and Debtor agrees not to
assert against any such assignee, or assignee's assigns, any defense, set-off, recoupment claim or counterclaim which Debtor has or may at any time have against Secured Party for any
reason whatsoever. Debtor agrees that if Debtor receives written notice of an assignment from Secured Party, Debtor will pay all amounts payable under any assigned Debt Documents to such assignee or
as instructed by Secured Party. Debtor also agrees to confirm in writing receipt of the notice of assignment as may be reasonably requested by Secured Party or assignee. 

        (b)   All
notices to be given in connection with this Agreement shall be in writing, shall be addressed to the parties at their respective addresses set forth in this
Agreement (unless and until a different address may be specified in a written notice to the other party), and shall be deemed given (i) on the date of receipt if delivered in hand or by
facsimile transmission, (ii) on the next business day after being sent by express mail, and (iii) on the fourth business day after being sent by regular, 

registered
or certified mail. As used herein, the term "business day" shall mean and include any day other than Saturdays, Sundays, or other days on which commercial banks in New York, New York are
required or authorized to be closed. 

        (c)   Secured
Party may correct patent errors and fill in all blanks in this Agreement or in any Collateral Schedule consistent with the agreement of the parties. 

        (d)   Time
is of the essence of this Agreement. This Agreement shall be binding, jointly and severally, upon all parties described as the "Debtor" and their respective heirs,
executors, representatives, successors and assigns, and shall inure to the benefit of Secured Party, its successors and assigns. 

        (e)   This
Agreement and its Collateral Schedules constitute the entire agreement between the parties with respect to the subject matter of this Agreement and supersede all
prior understandings (whether written, verbal or implied) with respect to such subject matter. THIS AGREEMENT AND ITS COLLATERAL SCHEDULES SHALL NOT BE CHANGED OR TERMINATED ORALLY OR BY COURSE OF
CONDUCT, BUT ONLY BY A WRITING SIGNED BY BOTH PARTIES. Section headings contained in this Agreement have been included for convenience only, and shall not affect the construction or interpretation of
this Agreement. 

        (f)    This
Agreement shall continue in full force and effect until all of the Indebtedness has been indefeasibly paid in full to Secured Party or its assignee. The surrender,
upon payment or otherwise, of any Note or any of the other documents evidencing any of the Indebtedness shall not affect the right of Secured Party to retain the Collateral for such other Indebtedness
as may then exist or as it may be reasonably contemplated will exist in the future. This Agreement shall automatically be reinstated if Secured Party is ever required to return or restore the payment
of all or any portion of the Indebtedness (all as though such payment had never been made). 

        (g)   Debtor
authorizes Secured Party to use its name, logo and/or trademark without notice to or consent by Debtor, in connection with certain promotional materials that
Secured Party may disseminate to the public. The promotional materials may include, but are not limited to, brochures, video tape, internet website, press releases, advertising in newspaper and/or
other periodicals, lucites, and any other materials relating the fact that Secured Party has a financing relationship with Debtor and such materials may be developed, disseminated and used without
Debtor's review. Nothing herein obligates Secured Party to use Debtor's name, logo and/or trademark, in any promotional materials of Secured Party. 

        (h)   THIS
AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL IN ALL RESPECTS BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE
STATE OF CONNECTICUT (WITHOUT REGARD TO THE CONFLICT OF LAWS PRINCIPLES OF SUCH STATE), INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE, REGARDLESS OF THE LOCATION OF THE COLLATERAL. 

        IN WITNESS WHEREOF, Debtor and Secured Party, intending to be legally bound hereby, have duly executed this Agreement in one or more
counterparts, each of which shall be deemed to be an original, as of the day and year first aforesaid.

PROMISSORY NOTE

                                         
       

(Date)  

FOR
VALUE RECEIVED, Amphastar Pharmaceuticals, Inc. a corporation located at the address stated below
("Maker") promises, jointly and severally if more than one, to pay to the order of General Electric Capital
Corporation or any subsequent holder hereof (each, a "Payee") at its office located at 83 Wooster Heights Road, Danbury, CT
06810 or at such other place as Payee or the holder hereof may designate, the principal sum of Five Million and 00/100 Dollars
($5,000,000), with interest on the unpaid principal balance, from the date hereof through and including dates of payment, at a floating per annum interest rate ("Contract
Rate") as hereinafter calculated. 

The
Contract Rate shall be equal to the sum of (i) Five and Fifty-Two Hundredths percent (5.52%) per annum plus (ii) a variable per annum interest rate ("Current LIBOR"),
which shall be equal to the rate listed for three month London Interbank Offered Rate ("LIBOR"), which is published in the "Money Rates" column of the Wall Street Journal, Eastern Edition (or, in the
event such rate is not so published, in such other nationally recognized publication as Payee may specify) on the first Business Day of the calendar month (notwithstanding any statement in such
publication as to the effective date of any published rate). As used herein, the term "Business Day" shall mean and include any calendar day other than a day on which all commercial banks in the City
of New York, New York are required or authorized to be closed. 

Subject
to the other provisions hereof, the principal and interest on this Note is payable in lawful money of the United States in Forty Eight (48) consecutive monthly installments as follows: 

	Periodic Installment
 
	 	Amount

	Forty-Eight (48) @	 	$	124,948.19

each
("Periodic Installment") and a final installment which shall be in the amount of the total outstanding unpaid principal and interest. The first Periodic Installment shall be due and payable on
                        and the following Periodic Installments shall be due and payable on the same day of each succeeding period
(each, a "Payment Date"). All payments shall be applied first to interest and
then to principal. The acceptance by Payee of any payment which is less than payment in full of all amounts due and owing at such time shall not constitute a waiver of Payee's right to receive payment
in full at such time or at any prior or subsequent time. Interest shall be calculated on the basis of a 360 day year (361 day leap year) and will be charged at the Contract Rate for each
calendar day on which any principal is outstanding. 

The
amount and number of the Periodic Installments will not change with fluctuations in the Contract Rate. Any increase in the Contract Rate shall be reflected by a corresponding decrease in the
portion of the Periodic Installment credited to the remaining unpaid principal balance. Any decrease in the Contract Rate shall be reflected as a corresponding increase in the portion of the Periodic
Installment credited to the remaining unpaid principal balance. Notwithstanding the foregoing, at the end of each three (3) month period commencing with the first Payment Date hereof, Maker
agrees to pay to Payee forthwith an additional sum ("Quarterly Payment") sufficient to amortize the unpaid principal over the balance of the original term hereof at the Contract Rate applicable for
the first Periodic Installment. 

If,
and for so long as, the amount of interest due exceeds the amount of the Periodic Installment, Maker agrees to pay forthwith, in addition to (i) any Periodic Installment then due and
(ii) any Quarterly Payment, the amount by which said interest exceeds the Periodic Installment. In the event interest only is required to be paid during any period, the interest for such period
shall be due and payable monthly as it accrues and shall be calculated on the unpaid principal balance existing at the commencement of such period. 

The
Contract Rate shall be subject to a quarterly adjustment (up or down) in accordance with the pricing grid set forth below, effective upon delivery of audited annual financial statements and
internally generated quarterly financial statements: 

	Debt Service Coverage Ratio

As defined below
 
	 	Contract Rate

	>1:40: 1 but < 1.75:1	 	LIBOR + 5.52%
	>1:75: 1 but < 2.00:1	 	LIBOR + 5.02%
	>2.00: 1 but < 2.25:1	 	LIBOR + 4.52%
	>2.25: 1 but < 2.50:1	 	LIBOR + 4.02%
	>2.50: 1	 	LIBOR + 3.50%

Downward
adjustments will only take effect (and only remain effective) provided no default has occurred and is continuing. 

"Debt
Service Coverage Ratio" shall be computed using the following formula: 

EBITDA
(defined as Q1 '05 × 4, Q2 '05 × 2, Q3 '05 and thereafter on a rolling 12 month basis)—Unfunded Capex (excluding the first
$6,000,000 and the unfunded calculation only applies to unfunded payments expected to be made in the next 12 months)—Less Dividends] divided by [principal
and interest payments on indebtedness for borrowed money due in the next twelve months] 

The
Maker hereby expressly authorizes the Payee to insert the date value is actually given in the blank space on the face hereof and on all related documents pertaining hereto. 

This
Note may be secured by a security agreement, chattel mortgage, pledge agreement or like instrument (each of which is hereinafter called a "Security
Agreement"). 

Time
is of the essence hereof. If any installment or any other sum due under this Note or any Security Agreement is not received within ten (10) days after its due date, the Maker agrees to
pay, in addition to the amount of each such installment or other sum, a late payment charge of five percent (5%) of the amount of said installment or other sum, but not exceeding any lawful maximum.
If (i) Maker fails to make payment of any amount due hereunder within ten (10) days after the same becomes due and payable; or (ii) Maker is in default under, or fails to perform
under any term or condition contained in any Security Agreement, then the entire principal sum remaining unpaid, together with all accrued interest thereon and any other sum payable under this Note or
any Security Agreement, at the election of Payee, shall immediately become due and payable, with interest thereon at the lesser of eighteen percent (18%) per annum or the highest rate not prohibited
by applicable law from the date of such accelerated maturity until paid (both before and after any judgment). 

The
Maker may prepay in full, but not in part, its entire indebtedness hereunder upon payment of the entire indebtedness plus an additional sum as a premium equal to the sum of: 

        (a)   the
following percentages of the remaining principal balance for the indicated period:

Prior to the first annual anniversary date of this Note: Not Allowed Thereafter and prior to the second annual anniversary date of this Note: Five percent (5%) Thereafter and prior to the third annual
anniversary date of this Note: Four and One Half percent (4.5%) Thereafter and prior to the fourth annual anniversary date of this Note: Four percent (4%) and zero percent (0%) thereafter, plus all
other sums due hereunder or under any Security Agreement. 

It
is the intention of the parties hereto to comply with the applicable usury laws; accordingly, it is agreed that, notwithstanding any provision to the contrary in this Note or any Security
Agreement, in no event shall this Note or any Security Agreement require the payment or permit the collection of interest in excess of the maximum amount permitted by applicable law. If any such
excess interest is contracted for, charged or received under this Note or any Security Agreement, or if all of the principal balance shall be prepaid, so that under any of such circumstances the
amount of interest contracted for, charged or received under this Note or any Security Agreement on the principal balance shall exceed the maximum amount of interest permitted by applicable law, then
in such event (a) the provisions of this paragraph shall govern and control, (b) neither Maker nor any other person or entity 

now
or hereafter liable for the payment hereof shall be obligated to pay the amount of such interest to the extent that it is in excess of the maximum amount of interest permitted by applicable law,
(c) any such excess which may have been collected shall be either applied as a credit against the then unpaid principal balance or refunded to Maker, at the option of the Payee, and
(d) the effective rate of interest shall be automatically reduced to the maximum lawful contract rate allowed under applicable law as now or hereafter construed by the courts having
jurisdiction thereof. It is further agreed that without limitation of the foregoing, all calculations of the rate of interest contracted for, charged or received under this Note or any Security
Agreement which are made for the purpose of determining whether such rate exceeds the maximum lawful contract rate, shall be made, to the extent permitted by applicable law, by amortizing, prorating,
allocating and spreading in equal parts during the period of the full stated term of the indebtedness evidenced hereby, all interest at any time contracted for, charged or received from Maker or
otherwise by Payee in connection with such indebtedness; provided, however, that if any applicable state law is amended or the law of the United States of America preempts any applicable state law, so
that it becomes lawful for the Payee to receive a greater interest per annum rate than is presently allowed, the Maker agrees that, on the effective date of such amendment or preemption, as the case
may be, the lawful maximum hereunder shall be increased to the maximum interest per annum rate allowed by the amended state law or the law of the United States of America. 

The
Maker and all sureties, endorsers, guarantors or any others (each such person, other than the Maker, an "Obligor") who may at any time become liable
for the payment hereof jointly and severally consent hereby to any and all extensions of time, renewals, waivers or modifications of, and all substitutions or releases of, security or of any party
primarily or secondarily liable on this Note or any Security Agreement or any term and provision of either, which may be made, granted or consented to by Payee, and agree that suit may be brought and
maintained against anyone or more of them, at the election of Payee without joinder of any other as a party thereto, and that Payee shall not be required first to foreclose, proceed against, or
exhaust any security hereof in order to enforce payment of this Note. The Maker and each Obligor hereby waives presentment, demand for payment, notice of nonpayment, protest, notice of protest, notice
of dishonor, and all other notices in connection herewith, as well as filing of suit (if permitted by law) and diligence in collecting this Note or enforcing any of the security hereof, and agrees to
pay (if permitted by law) all expenses incurred in collection, including Payee's actual attorneys' fees. Maker and each Obligor agrees that fees not in excess of twenty percent (20%) of the amount
then due shall be deemed reasonable. 

THE MAKER HEREBY UNCONDITIONALLY WAIVES ITS RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF, DIRECTLY OR INDIRECTLY, THIS NOTE, ANY OF THE
RELATED DOCUMENTS, ANY DEALINGS BETWEEN MAKER AND PAYEE RELATING TO THE SUBJECT MATTER OF THIS TRANSACTION OR ANY RELATED TRANSACTIONS, AND/OR THE RELATIONSHIP THAT IS BEING ESTABLISHED BETWEEN MAKER
AND PAYEE. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL ENCOMPASSING OF ANY AND ALL DISPUTES THAT MAY BE FILED IN ANY COURT (INCLUDING, WITHOUT LIMITATION, CONTRACT CLAIMS, TORT CLAIMS, BREACH OF
DUTY CLAIMS, AND ALL OTHER COMMON LAW AND STATUTORY CLAIMS.) THIS WAIVER IS IRREVOCABLE MEANING THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND THE WAIVER SHALL APPLY TO ANY SUBSEQUENT
AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS NOTE, ANY RELATED DOCUMENTS, OR TO ANY OTHER DOCUMENTS OR AGREEMENTS RELATING TO THIS TRANSACTION OR ANY RELATED TRANSACTION. IN THE EVENT OF
LITIGATION, THIS NOTE MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE COURT.

This
Note and any Security Agreement constitute the entire agreement of the Maker and Payee with respect to the subject matter hereof and supercedes all prior understandings, agreements and
representations, express or implied. 

No
variation or modification of this Note, or any waiver of any of its provisions or conditions, shall be valid unless in writing and signed by an authorized representative of Maker and Payee. Any
such 

waiver,
consent, modification or change shall be effective only in the specific instance and for the specific purpose given. 

Any
provision in this Note or any Security Agreement which is in conflict with any statue, law or applicable rule shall be deemed omitted, modified or altered to conform thereto.
