Dr. Ellen Brady                                            August 5, 2002

Dear Ellen,

        On behalf of Esperion Therapeutics, Inc. (the "Company"), I am
     pleased to offer you a position with the Company. The following is an
     outline of the terms of this offer:

     1. The position offered is that of Senior Director of Clinical reporting on
        an interim basis to me. Upon hiring of a Sr. Vice President of Clinical
        and Regulatory, you will report to that individual.

     2. You shall be paid an initial monthly salary of $13,750 plus a bonus of
        up to 20% of base salary. The right to receive a bonus for the first
        year of employment or portion thereof for which the Company pays bonuses
        is dependent on continued employment during that period. The magnitude
        of the bonus, if any, will be determined, based upon achievement of a
        series of mutually agreed upon performance objectives/milestones.
        A proposed series of objectives/milestones will be developed between you
        and your supervisor.

     3. A benefits package will be provided to you, which are equivalent to that
        offered to other similarly situated employees with the Company.

     4. Esperion will provide you with a starting bonus of $50,000. In the event
        that your employment at Esperion is terminated by you within 12 months
        from the time of your full-time starting date, you will be required to
        immediately repay the starting bonus. In the event that your employment
        at Esperion is terminated by you after 12 months but before 24 months
        from the time of your full-time starting date, you will be required to
        repay 50% of the starting bonus. This repayment provision will not apply
        if the reason for termination is other than resignation or cause.

     5. Subject to meeting eligibility requirements, we intend to grant to you
        an option to purchase up to 50,000 shares of the Company's common stock
        under one of the Company's equity compensation plans, subject to the
        approval of our Board of Directors. The option grant will become
        effective on the date of such approval, and will have an exercise price
        that will be equal to or greater than the fair market value of a share
        of our stock on the date of such approval, as determined by the Board of
        Directors.  The terms and conditions of the option, along with the
        period during which the option will become exercisable, will be set
        forth in a Stock Option Agreement that you will be required to execute.

<PAGE>
     6. You will be required to execute the Company's standard forms of
        Non-Competition, as well as Confidentiality and Assignment Agreement.

     7. This employment relationship is one of employment at will. Either
        Esperion Therapeutics or you may terminate this employment agreement,
        with or without notice, and with or without cause at any time.

     8. If your employment is terminated by the Company for reasons other than
        cause, you will be provided a severance package of 6 months salary; with
        continuation of benefits during this period and 25% of your unvested
        options will automatically vest. Cause shall mean that the employee has
        engaged in disloyalty to the Company, including, without limitation,
        fraud, embezzlement, theft, commission of a felony or proven dishonesty
        in the course of his or her employment, has disclosed trade secrets or
        confidential information of the Company to persons not entitled to
        receive such information, or has engaged in such other behavior
        detrimental to the interests of the Company.  If you terminate your
        employment with the Company voluntarily or if your employment is
        terminated by the company for cause, you will forfeit the severance
        package, as well as any of your unvested stock options.

     If the terms of this offer are acceptable to you, please so indicate by
executing in the space provided below and fax to 734-222-1860, as well as mail
(an original copy) to the Company. Please respond to this offer within two weeks
from the date hereof. After this date (i.e. August 19, 2002) this offer may be
withdrawn at the discretion of the Company. If you have any questions, please
contact Susan Landauer, Human Resource Manager at 734-222-1826.

                             MASTER LEASE AGREEMENT

     Master Lease Agreement effective as of July 12, 2001, by and between
Southwest Michigan Innovation Center, Inc., a Michigan nonprofit corporation
("Lessor") and Esperion Therapeutics, Inc., a Delaware corporation ("Lessee").

     In consideration of the mutual agreements set forth in this Master Lease,
the payment of rent and other amounts as provided in this Master Lease, and any
equipment scheduled to be delivered pursuant to this Master Lease, the parties
agree as follows:

     1. Agreement to Lease. Lessor rents and leases to Lessee, and Lessee rents
and leases from Lessor, all of the tangible personal property listed on each
Equipment Schedule executed from time to time pursuant to this Master Lease
(with respect to any Equipment Schedule called the "Equipment"). The term
"Equipment" shall include all replacement parts, accessories or alterations
incorporated into or made to such tangible personal property. Each Equipment
Schedule shall be substantially in the form attached to this Master Lease as
Exhibit A (an "Equipment Schedule"), shall incorporate in it all the terms and
conditions of this Master Lease and shall contain such additional terms and
conditions as Lessor and Lessee shall agree upon.

     Notwithstanding any other provision, Lessor and Lessee jointly issued a
purchase order for a NMR Spectrometer on or after the effective date of this
Master Lease and Lessor paid to Lessee the sum of Two Hundred Sixty Eight
Thousand Two Hundred Dollars and No/100 ($268,200) with the Lessee of such
equipment on July 12, 2001, and paid an additional One Hundred Fourteen Thousand
One Hundred and no/100 ($114,100.00) to the Lessee on October 2, 2001. Lessor
intends to make an additional payment of Sixty Four Thousand Seven Hundred and
no/100 ($64,700.00) to Lessee. Lessor and Lessee acknowledge and agree that the
NMR Spectrometer shall be leased to Lessee pursuant to this Master Lease, as
evidenced by the attached Equipment Schedule and that the purchase price for the
NMR Spectrometer, including installation costs, shall be added to the Principal
Balance, as defined below, and recorded in the Payback Schedule, as defined
below. Lessee shall be entitled to payment of an additional Fifty-Three Thousand
and No/100 ($53,000.00) for reimbursement of the purchase of computer and lab
equipment to be used at the Southwest Michigan Innovation Center ("SMIC")
located at the Western Michigan University Business and Technology Park;
subject, however, to Esperion first entering into a sublease agreement for space
at SMIC and taking possession of those leased premises.

     2. Term. The term of this Master Lease shall begin on July 12, 2001 (the
"Commencement Date") and end seventy-two (72) months from the date of the last
drawdown under this Master Lease (the "Term"). This Master Lease cannot be
cancelled or terminated except as expressly permitted in this Master Lease. Upon
expiration of the Master Lease, Lessee shall purchase the Equipment for the
unamortized Principal Balance remaining under the Payback Schedule based upon
the payment terms described in Section 3

                                      _1_

<PAGE>

of this Master Lease.

     3. Rent and Payment; Net Lease. All sums paid by Lessor in connection with
the acquisition and installation of Equipment pursuant to this Master Lease
shall be recorded on the Payback Schedule. The parties agree that the Principal
Balance is defined as the amount reimbursed or paid to Lessee by Lessor for the
purchase of Equipment less any principal payments made under the applicable
Payback Schedule. Lessee shall pay to Lessor as rent the outstanding Principal
Balance plus interest according to the following terms beginning on the
Commencement Date:

Months                 Payment Amount

1 - 12                 No payment; interest will accrue on the outstanding
                       Principal Balance at four percent (4%) per annum.

13 - 36                Monthly interest only payments equal to four percent
                       (4%) per annum of the outstanding Principal Balance,
                       plus one  twenty-fourth (1/24th)of the interest accrued
                       during months 1 - 12.

37 - 72                Monthly principal and interest payments calculated using
                       a ten (10) year amortization at four percent (4%) per
                       annum of the outstanding Principal Balance.  The
                       outstanding Principal Balance shall be paid in full at
                       the expiration of the Term.

     Rental Payments shall be monthly and shall be due and payable in advance on
the first day of each calendar month (each such date being called a "Monthly
Rent Payment Date"). Rent shall be paid to Lessor by check or wire transfer so
as to constitute immediately available funds at the address of Lessor set forth
above or at such other place as Lessor shall designate in writing or if to an
Assignee (as defined in Section 14 below) of Lessor, at such place as such
Assignee shall designate in writing. All amounts shall be paid free and clear of
all claims, demands or set offs against Lessor or such Assignee. Lessor shall
not be required to invoice Lessee for each payment, however, Lessor shall
provide an amortization schedule, which will be incorporated into Exhibit B and
shall state due dates and amounts (the "Payback Schedule")

     Time is of the essence of this Master Lease. Lessee agrees to pay interest
on any late payment for the period beginning fifteen (15) days after the date
such late payment was due through the date such late payment is made at the
lesser of ten percent (10%) per annum or the maximum rate allowed by law.

     The Master Lease shall be non-cancelable for its entire term and Lessee
shall have the right of prepayment, without penalty for the unpaid Principal
Balance.

                                      _2_

     LESSOR AND LESSEE ACKNOWLEDGE AND AGREE THAT LESSEE'S OBLIGATION TO PAY ALL
RENTAL AND ANY OTHER AMOUNTS PAYABLE BY LESSEE UNDER THIS MASTER LEASE, AS
EVIDENCED BY EXHIBIT B, SHALL BE ABSOLUTE AND UNCONDITIONAL AND, EXCEPT IF THE
EQUIPMENT HAS BEEN DAMAGED TO THE EXTENT NOT REASONABLY OPERABLE BY LESSEE OR
DESTROYED AS A RESULT OF THE USE OF THE EQUIPMENT BY WESTERN MICHIGAN UNIVERSITY
FACULTY OR STUDENTS, SHALL NOT BE SUBJECT TO ANY ABATEMENT, REDUCTIONS, SET OFF,
DEFENSE, COUNTERCLAIM, INTERRUPTION, DEFERMENT OR RECOUPMENT FOR ANY REASON
WHATSOEVER, AND THAT SUCH PAYMENT SHALL BE AND CONTINUE TO BE PAYABLE IN ALL
EVENTS.

     4. Taxes and Fees. Lessee covenants and agrees to pay when due or reimburse
and indemnify and hold Lessor harmless from and against all taxes, fees or other
charges of any nature whatsoever (together with any related interest or
penalties not arising from negligence on the part of Lessor) now or subsequently
imposed or assessed ("Taxes") against Lessor, Lessee or the Equipment of any
Federal, state, county, or local governmental authority upon or with respect to
the Equipment or upon the ordering, purchase, sale, ownership, delivery,
leasing, possession, use, operation, return or other disposition, or upon the
rents, receipts, or earnings arising from the Equipment upon or with respect to
any Equipment Schedule, if any. If Lessee is required by law or administrative
practice to make any report or return with respect to such Taxes, Lessee shall
promptly notify Lessor in writing and shall cooperate with Lessor to confirm
that such reports are properly filed and accurately reflect Lessor's interest in
the Equipment.

     5. Insurance. Lessee shall obtain and maintain for the Term of the Master
Lease, at its own expense, property damage and general liability insurance,
including without limitation, loss by fire (including so-called extended
coverage), theft, collision, and such other risks of loss as are customarily
insured against the type of equipment leased under the Master Lease and by the
businesses in which Lessee is engaged, in such amounts and in such form, which
are reasonable with respect to the risk covered. All such insurance policies
shall protect Lessor and Lessee as named insureds, and shall provide that all
losses shall be payable to Lessor, adjusted solely with Lessor. On Lessor's
request, Lessee shall provide evidence of such insurance to Lessor within five
(5) days of such request. Notwithstanding anything to the contrary herein, the
parties agree that if the Equipment is damaged to the extent not reasonably
operable by Lessee or destroyed as a result of the use of the Equipment by
Western Michigan University faculty or students, then Lessor will be responsible
for replacing or repairing the damaged or destroyed Equipment to the extent such
repair or replacement costs are not covered by insurance.

     6. Location and Maintenance. Lessee shall use, operate and keep the
Equipment at McCracken Hall, Haenicke Hall, or the Southwest Michigan Innovation
Center. Lessee shall, at its sole expense, at all times during the Term of the
Master Lease, maintain the Equipment in good repair, condition and appearance
and protect the Equipment

                                      _3_

<PAGE>

from deterioration other than normal wear and tear. Lessee shall not use
the Equipment for any purpose other than that for which it was designed nor in
violation of any restriction on use set forth in the applicable Equipment
Schedule.

     Upon reasonable notice by Lessor, which will not exceed thirty-six (36)
hours, Lessee shall at all reasonable times during business hours, make the
Equipment available to the Lessor for inspection at the place where it is
normally located and shall make Lessee's log and maintenance records pertaining
to the Equipment available to Lessor for inspection, provided that a
representative of Lessee accompanies Lessor.

     7. Title; Financing Statement; Liens. Lessor and Lessee intend that this
Master Lease is an agreement of the lease. Accordingly, title to the Equipment
shall at all times remain with Lessor and nothing contained in any Equipment
Schedule shall give or convey to Lessee any right, title or interest in or to
the Equipment, except as a Lessee, as set forth in this Master Lease. Lessor has
and is relying upon its residual interest in the Equipment at the termination of
this Master Lease, whether by expiration, default or otherwise. Lessee appoints
and authorized Lessor, as its agent and attorney-in-fact, to execute and file,
on behalf of Lessee, any Uniform Commercial Code financing statements.

     Lessee shall, at its expense, protect and defend Lessor's title as well as
the interest of any Assignee against all persons claiming against or through
Lessee and shall at all times keep the Equipment free and clear from any legal
process, liens, or encumbrances, whatsoever (except those placed by Lessor) and
shall give Lessor immediate written notice of any liens and shall indemnify and
hold Lessor and any Assignee harmless from and against any loss caused by such
liens.

     8. Risk of Loss. Until such time as the Equipment is returned and delivered
to and accepted by Lessor pursuant to the terms of this Master Lease, Lessee
assumes and shall bear the entire risk of loss, damage, theft and destruction of
and to the Equipment or any portion of it from any cause whatsoever, commencing
with delivery of such Equipment to Lessee. No loss, damage, theft or destruction
of the Equipment for which Lessee has the risk of loss shall relieve Lessee in
any way from the obligations to pay rental or perform any other of its
obligations under this Master Lease. Notwithstanding anything to the contrary
herein, the parties agree that if the Equipment is damaged to the extent not
reasonably operable by Lessee or destroyed as a result of the use of the
Equipment by Western Michigan University faculty or students under this
Agreement, then Lessor will be responsible for replacing or repairing the
damaged or destroyed Equipment to the extent not covered by insurance. Lessee
shall promptly notify Lessor in writing of any loss, theft, damage or
destruction of the Equipment. In the event of such a loss, damage, theft or
destruction of any item of the Equipment, Lessee, at the option of Lessor,
shall:

        (a) Promptly place, at Lessee's expense, the Equipment in good repair,
            condition and working order in accordance with the manufacturer's
            specifications and to the reasonable satisfaction

                                      _4_

<PAGE>

            of Lessor; or

        (b) Promptly replace, at Lessee's expense, the Equipment with like
            Equipment of the same or a later model and specifications, with the
            additions, in good repair, condition and working order in accordance
            with the manufacturer's specifications and to the reasonable
            satisfaction of Lessor.

     In the event Lessor elects or requires Lessee to repair or replace any such
item of Equipment pursuant to (a) or (b) above, continuation of this Master
Lease, and/or any Equipment Schedule and the continued payment of rent shall not
be affected because of such loss, damage or destruction and the resulting repair
or replacement and the insurance proceeds received by Lessor, if any, pursuant
to Section 5 above, after the use of such funds to pay any accrued and unpaid
rentals under this Master Lease, shall be paid to Lessee upon Lessee's
furnishing proof reasonably satisfactory to Lessor that such repair or
replacement has been completed in a manner reasonably satisfactory to Lessor and
fully paid for by Lessee.

     9. No Lien or Modifications. Lessee shall not create or incur any mortgage,
lien, pledge or other encumbrance or attachment of any kind upon the Equipment.
Lessee shall not make any changes to the Equipment, except as permitted by
Lessor, except as required by any maintenance obligations of the Master Lease
Agreement. Lessee shall not assign or in any way dispose of all or any part of
its rights or obligations under the Master Lease Agreement.

     10. Selection; Finance Lease Status. Lessee acknowledges, represents and
warrants that is has made the selection of both (a) the Equipment and (b) the
supplier(s) (individually, a "Supplier" and collectively "Suppliers") from whom
Lessor is to purchase the Equipment, based on Lessee's own judgment and
expressly disclaims any reliance upon statements made by the Lessor. Lessee
requests that Lessor order and purchase the Equipment from Suppliers and arrange
for delivery of such Equipment to Lessee. Lessee authorizes Lessor to insert in
each Equipment Schedule the serial number and other identifying data of the
Equipment.

     To the extent possible, the parties agree that this Master Lease and each
Equipment Schedule are intended to qualify as a "finance lease" under Article 2A
of the Uniform Commercial Code ("UCC"). Lessee acknowledges that Lessee selected
and approved all Equipment leased under this Master Lease.

     11. Disclaimer of Warranties. LESSOR IS NOT THE MANUFACTURER OR SUPPLIER OF
ANY OF THE EQUIPMENT. ACCORDINGLY, LESSOR MAKES NO REPRESENTATION, WARRANTY OR
COVENANT, EITHER EXPRESS OR IMPLIED, AS TO ANY MATTER WHATSOEVER, INCLUDING

QUALITY OF THE MATERIAL OR WORKMANSHIP OF THE EQUIPMENT OR ANY CONFORMITY OF THE
EQUIPMENT TO THE PROVISIONS AND SPECIFICATIONS OF ANY PURCHASE ORDER(S) RELATING
TO THE EQUIPMENT. ALL EQUIPMENT SHALL BE ACCEPTED AND LEASED BY LESSEE "WHERE
IS", "AS IS", AND "WITH ALL FAULTS". LESSOR SHALL NOT BE RESPONSIBLE FOR ANY
PATENT OR LATENT DEFECTS IN ANY EQUIPMENT, FOR ANY INFRINGEMENT OF ANY PATENT,
TRADEMARK, OR COPYRIGHT, OR FOR DAMAGES WHETHER ACTUAL, SPECIAL, CONSEQUENTIAL
OR INCIDENTAL ARISING FROM ANY CAUSE WHATSOEVER. Lessor shall not be liable to
Lessee or any third party for consequential, incidental, special or exemplary
damages occurring out of or related to the Master Lease, or the transactions
contemplated under the Master Lease, except for Lessor's gross negligence or
willful misconduct. Lessee further understands and agrees that no employee or
agent of Lessor is authorized to waive or alter any term or condition of this
Master Lease or any Equipment Schedule, if any, including without limitation,
this Section 11.

     Lessor assigns to Lessee for and during the term of this Master Lease all
of its right, title and interest in and to any warranty made by any manufacturer
or Supplier of the Equipment to the extent the same is assignable. Lessor makes
no warranties independent of those made by such manufacturer and Lessee agrees
that it will look solely to such manufacturer. Lessee agrees to resolve all such
warranty claims directly with such manufacturer or Supplier. Provided that no
Event of Default under this Lease is then existing, Lessor shall cooperate with
Lessee to resolve such warranty claims in good faith and by appropriate
proceedings at Lessee's sole cost and expense. No such warranty claim shall
affect in any manner the unconditional obligation fo Lessee to make rent and
other payments under this Master Lease.

     12. Representations and Warranties of Lessee. Lessee represents, warrants
and covenants that with respect to the Master Lease and each Equipment Schedule
executed pursuant to the Master Lease:

        (a) Lessee has been duly authorized by all necessary corporate action to
            execute, deliver and perform this Master Lease, and will not violate
            Lessee's articles of incorporation, by-laws, or require the approval
            of any of its shareholders, other than those individuals executing
            this Master Lease.

        (b) The individual executing this Master Lease was duly authorized to
            do so.

        (c) The Master Lease, each Equipment Schedule and all Exhibits to this
            Master Lease constitute legal, valid and binding agreements of
            Lessee enforceable in accordance with their respective terms.

        (e) ALL EQUIPMENT IS LEASED FOR BUSINESS PURPOSES ONLY OR TO ALLOW FOR
            ACCESS TO WESTERN MICHIGAN UNIVERSITY, AND NOT FOR PERSONAL, FAMILY
            OR HOUSEHOLD PURPOSES.

     13. Assignment by Lessee. WITHOUT LESSOR'S PRIOR WRITTEN CONSENT, LESSEE
SHALL NOT (A) ASSIGN, TRANSFER, PLEDGE OR OTHERWISE DISPOSE OF THIS MASTER

of the Equipment or any of its rights, interests or obligations with respect to
them, including, without limitation, all rental and other sums due or to become
due under any Schedule to one or more persons or entities (each an "Assignee").
LESSEE ACKNOWLEDGES THAT ANY SUCH ASSIGNMENT OR TRANSFER BY LESSOR SHALL NOT
MATERIALLY IMPAIR LESSEE'S PROSPECT OF OBTAINING RETURN PERFORMANCE BY LESSOR,
MATERIALLY CHANGE LESSEE'S DUTIES OR OBLIGATIONS UNDER THE APPLICABLE EQUIPMENT
SCHEDULE, NOR MATERIALLY INCREASE THE BURDENS OR RISKS IMPOSED ON LESSEE. LESSEE
FURTHER AGREES THAT ANY SUCH ASSIGNMENT OR TRANSFER SHALL BE PERMITTED EVEN IF
IT COULD BE DEEMED TO MATERIALLY EFFECT THE INTERESTS OF LESSEE. Lessee shall,
upon receipt of notice of assignment from Lessor, be bound by any such
assignment. Any Assignee shall have all of the rights and obligations of Lessor
under this Master Lease and the applicable Equipment Schedule. Upon receipt of

willful misconduct of such indemnified party. In addition, the parties agree

or destroyed as a result of the use of the Equipment by Western Michigan
University faculty or students under this Agreement, then Lessor will indemnify
Lessee for the costs associated with replacing or repairing the damaged or
destroyed Equipment that are not covered by insurance. Both Lessee and Lessor
agree to give the other party prompt notice of any claim or liability that may
give rise to any indemnification under this Section. This Section shall remain
in effect notwithstanding the expiration or termination of this Master Lease or
any Equipment Schedule insofar as it relates to an event that occurred prior to
such expiration or termination.

             this Master Lease as and when the same becomes due and payable and
