Company agrees to continue to pay the Executive a base salary at the annualized
rate of $545,000 (Base Salary).  The

performance-based annual bonus for each fiscal year of the Term (the Annual
Bonus). The Annual Bonus shall be based  2


upon annual quantitative
and qualitative performance targets as established by the Board in its sole
discretion in accordance with the Companys bonus plan; provided, that

Employment Period.  4.2           At the election of the Company, for
Cause (as defined below), immediately upon written notice by the Company to the
Executive, which notice shall identify the Cause upon which termination is
based.  For the purposes of this Section 4.2,
Cause for termination shall mean:  (a) the
Executives willful and continued failure to substantially perform his
reasonable assigned duties (other than any such failure resulting from
incapacity due to physical or mental illness or any failure after the Executive
gives notice of termination for Good Reason and Good Reason exists), which

performance is received by the Executive from the Board of Directors of the
Company which specifically identifies the manner in which the Board of
Directors believes the Executive has not substantially performed the Executives
duties; (b) the Executives willful engagement in illegal conduct or gross
misconduct which is materially and demonstrably injurious to the Company; or (c) a
material breach of Section 6 or 7 of this Agreement by the Executive.  For purposes of this Section 4.2, no act
or failure to act by the Executive shall be considered willful unless it is
done, or omitted to be done, in bad faith and without reasonable belief that
the Executives action or omission was in the best interests of the Company.  4.3           Upon the death or disability of the
Executive.  As used in this Agreement,
the term disability shall mean the Executives absence from the full-time
performance of the Executives duties with the Company for one hundred eighty
(180) consecutive calendar days as  4


a result of incapacity
due to mental or physical illness which is determined to be total and permanent
by a physician selected by the Company or its insurers and acceptable to the
Executive or the Executives legal representative.  4.4           At the election of the Executive for
Good Reason as defined herein.  The
Executive may terminate his employment for Good Reason at any time, following
30-days prior written notice of such termination to the Company. Such notice
shall provide factual details of the basis behind such termination and the
Company shall have a thirty (30) day period thereafter to cure such
matter.  As used herein, the term Good
Reason shall mean:  (a) a material
breach by the Company of the terms of this Agreement, including the failure to
pay Base Salary or any Annual Bonus when due; or (b) any material adverse
change by the Company in Executives titles, authorities, duties,
responsibilities or lines of reporting inconsistent with the terms hereof or
the assignment to Executive by the Company of titles, authorities, duties,
responsibilities or lines of reporting inconsistent with the terms hereof, or (c) a
relocation of the offices of the Company where the Executive is working to an
area more than forty (40) miles from the location of such offices as of the
date hereof.  4.5           At the election of the Executive
without Good Reason, upon not less than sixty (60) calendar days prior written
notice of termination by the Executive to the Company; provided, however,
that the Company may, in its sole discretion, determine that the termination of
the Executive shall become effective immediately and in which case the
termination shall still be considered at the election of the Executive without
Good Reason.  4.6           At the election of the Company,
without Cause, upon not less than sixty (60) days written notice to Executive.  5

Control shall have the meaning set forth in the ERA.  5.Effect of Termination.  5.1           Non-Renewal, Termination Without
Good Reason By the Executive or Termination For Cause By the Company.  In the event the Executives employment is
terminated by non-renewal pursuant to Section 4.1, for Cause by the
Company pursuant to Section 4.2, or at the election of the Executive
pursuant to Section 4.5, the Company shall pay to the Executive the
compensation and benefits otherwise payable to him under Section 3 through
the last calendar day of his actual employment by the Company.  5.2           Termination for Death or
Disability.  In the event the
Executives employment is terminated by death or because of disability pursuant
to Section 4.3, the Company shall pay to the estate of the Executive or to
the Executive, as the case may be, (A) within thirty (30) days of the date
of the Executives death or determination of disability, the compensation which
would otherwise be payable to the Executive up to the end of the month in which
the termination of his employment because of death or disability occurs; and (B) an
annual bonus, payable when bonuses are paid for that year, in an amount equal
to the total bonus he would be paid for such year, if any, multiplied by a
fraction, the numerator of which is the number of days in the year that have
elapsed since January 1 and the denominator of which is 365 (a Pro Rata
Bonus).  5.3Termination By the Executive With Good Reason or
By the Company Without Cause.  In
the event the Executives employment is terminated by the Executive with  6


Good Reason pursuant to Section 4.4
or by the Company without Cause pursuant to Section 4.6, the Company shall

Schedule B hereto, the Company shall(a) continue
to pay the Executive the Base Salary for twenty four (24) months in accordance
with the Companys regular payroll practices; (b) pay the Executive a Pro

allow the Executive to participate in the Companys executive retiree health
benefit program based on the same cost sharing arrangement that applied

terminated pursuant to Section 4.7 by the Company or by the Executive
within 24 months following the Change in Control Date as defined in the ERA,
the Executive will be entitled to the benefits set forth in the ERA in
accordance with the terms of the ERA.  5.5Participation
in Executive Retirement Health Benefit Program.  Following the date of the Executives
termination and, if applicable, the twenty-four (24) month period referred to
in Section 5.3(d) or the period referred to in Section 4.2(a)(ii) of
the ERA, in the event the Executive elects to participate in the Companys
executive retiree health benefit program set forth on Exhibit A
hereto (the Program), he will reimburse the Company with respect to his
participation in the Program at the lesser of (a) the actual cost to the
Company of  7


the employees
participation and (b) the rate applicable to former employees of the
Company to elect COBRA health coverage.  5.6           Payments Subject to Section 409A.  (a)           Subject to thisSection 5.6,
payments or benefits under Section 5 
shall begin only upon the date of a separation from service of the
Executive (determined as set forth below) which occurs on or after the
termination of the Executives employment. 
The following rules shall apply with respect to distribution of the
payments and benefits, if any, to be provided to the Executive under Section 5,
as applicable:  (i)            It is intended that each installment
of the payments and benefits provided under Section 5  shall be treated as a separate payment for
purposes of Section 409A of the Code and the guidance issued thereunder (Section 409A).  Neither the Company nor the Executive shall
have the right to accelerate or defer the delivery of any such payments or
benefits except to the extent specifically permitted or required by Section 409A.  (ii)           If, as of the date of the separation
from service of the Executive from the Company, the Executive is not a specified
employee (within the meaning of Section 409A), then each installment of
the payments and benefits shall be made on the dates and terms set forth in Section 5.  (iii)          If, as of the date of the separation
from service of the Executive from the Company, the Executive is a specified
employee (within the meaning of Section 409A), then:  (1)           Each
installment of the payments and benefits due under Section 5 that, in
accordance with the dates and terms set forth herein, will in all
circumstances, regardless of when the separation from service occurs, be paid
within the Short-  8


Term
Deferral Period (as hereinafter defined) shall be treated as a short-term
deferral within the meaning of Treasury Regulation Section 1.409A-1(b)(4) to
the maximum extent permissible under Section 409A.  For purposes of this Agreement, the Short-Term
Deferral Period means the period ending on the later of the 15th
day of the third month following the end of the Executives tax year in which
the separation from service occurs and the 15th day of the third
month following the end of the Companys tax year in which the separation from
service occurs; and  (2)           Each
installment of the payments and benefits due under Section 5 that is not
described inSection 5.6 (a)(iii)(1) and that would,
absent this subsection, be paid within the six-month period following the separation
from service of the Executive from the Company shall not be paid until the
date that is six months and one day after such separation from service (or, if
earlier, the Executives death), with any such installments that are required
to be delayed being accumulated during the six-month period and paid in a lump
sum on the date that is six months and one day following the Executives
separation from service and any subsequent installments, if any, being paid in
accordance with the dates and terms set forth herein; provided, however,
that the preceding provisions of this sentence shall not apply to any
installment of payments and benefits if and to the maximum extent that that
such installment is deemed to be paid under a separation pay plan that does not
provide for a deferral of compensation by reason of the application of Treasury
Regulation 1.409A-1(b)(9)(iii) (relating to separation pay upon an
involuntary separation from service). 
Any installments that qualify for the exception under Treasury
Regulation Section 1.409A-1(b)(9)(iii) must be paid no later than the
last day of the Executives second taxable year following his taxable year in
which the separation from service occurs.  9


(b)           The determination of whether and when
a separation from service of the Executive from the Company has occurred shall
be made and in a manner consistent with, and based on the presumptions set
forth in, Treasury Regulation Section 1.409A-1(h).  Solely for purposes of thisSection 5.6
(b), Company shall include all persons with whom the Company would be
considered a single employer under Section 414(b) and 414(c) of
the Code.  (c)           All reimbursements and in-kind
benefits provided under the Agreement shall be made or provided in accordance
with the requirements of Section 409A to the extent that such
reimbursements or in-kind benefits are subject to Section 409A.  6.             Non-Competition
and Non-Solicitation.  (a)           While the Executive is employed by
the Company and for a period of twelve (12) months following the Executives
termination or cessation of such employment for any reason, the Executive will
not directly or indirectly:  (i)            Engage in any business or enterprise
(whether as an owner, partner, officer, employee, director, investor, lender,
consultant, independent contractor or otherwise, except as the holder of not
more than 5% of the combined voting power of the outstanding stock of a
publicly held company) that (A) is competitive with the Companys business
and (B) develops, designs, produces, markets, sells or renders any product
or service competitive with any product developed, produced, marketed, sold or
rendered by the Company while the Executive was employed by the Company;  (ii)           Either
alone or in association with
others, recruit or solicit, any person who was employed by the Company at any
time during the period of the Executives employment with the Company, except
for an individual whose employment with the Company has been terminated for a
period of six months or longer; and  10


(iii)          Either
alone or in association with
others, solicit, divert or take away, or attempt to divert or to take away, the
business or patronage of any of the clients, customers or accounts, or
prospective clients, customers or accounts, of the Company which were
contacted, solicited or served by the Executive while he was employed by the
Company.  (b)           If
any restriction set forth in this Section 6 is found by any court of competent jurisdiction to be unenforceable
because it extends for too long a period of time or over too great a range of
activities or in too broad a geographic area, it shall be interpreted to extend
only over the maximum period of time, range of activities or geographic area as
to which it may be enforceable.  (c)           The
Executive acknowledges that the
restrictions contained in this Agreement are necessary for the protection of
the business and goodwill of the Company and are considered by the Executive to
be reasonable for such purpose.  The
Executive agrees that any breach of this Agreement will cause the Company
substantial and irrevocable damage and therefore, in the event of any such
breach, in addition to such other remedies which may be available, the Company
shall have the right to seek specific performance and injunctive relief without
posting a bond.  (d)           The
geographic scope of this Section shall extend to anywhere the Company or
any of its subsidiaries is doing business during the Term or has plans, during
the Term, to do business.  (e)           The Executive agrees to provide a copy of this Agreement to all
person and Entities with whom the Executive
seeks to be hired or do business before accepting employment or engagement with
any of them.  11


(f)            If
the Executive violates the provisions
of this Section, the Executive shall continue to be held by the restrictions
set forth in this Section, until a period equal to the period of restriction
has expired without any violation.  7.Proprietary
Information and Developments.  7.1           Proprietary
Information.  (a)           The Executive agrees that all
information, whether or not in writing, of a private, secret or confidential
nature concerning the Companys business, business relationships or financial
affairs (collectively, Proprietary Information) is and shall be the exclusive
property of the Company.  By way of
illustration, but not limitation, Proprietary Information may include
discoveries, inventions, products, product improvements, product enhancements,
processes, methods, techniques, formulas, compositions, compounds, negotiation
strategies and positions, projects, developments, plans (including business and
marketing plans), research data, clinical data, financial data (including
sales, costs, profits and pricing methods), personnel data, computer programs
(including software used pursuant to a license agreement), customer and
supplier lists, and contacts at or knowledge of customers or prospective
customers of the Company.  Except as
required by applicable law, the Executive will not disclose any Proprietary
Information to any person or entity other than employees of the Company or use
the same for any purposes (other than in the performance of his duties as an
employee of the Company) without prior written approval from the Chief
Executive Officer, either during or after his employment with the Company,
unless and until such Proprietary Information has become public knowledge
without fault by the Executive.  (b)           The Executive agrees that all files,
documents, letters, memoranda, reports, records, data, sketches, drawings,
methods, laboratory notebooks, program listings,  12


computer equipment or
devices, computer programs or other written, photographic, or other tangible
material containing Proprietary Information, whether created by the Executive
or others, which shall come into his custody or possession, shall be and are
the exclusive property of the Company and are to be used by the Executive only
in the performance of his duties for the Company.  All such materials or copies thereof and all
tangible property of the Company in the custody or possession of the Executive
shall be delivered to the Company upon the earlier of (i) a request by the
Company or (ii) termination of his employment.  After such delivery, the Executive shall not
retain any such materials or copies thereof or any such tangible property.  (c)           The Executive agrees that his
obligation not to disclose or to use information and materials of the types set
forth in subsections (a) and (b) above, and his obligation to return
materials and tangible property set forth in subsection (b) above, also
extends to such types of information, materials and tangible property of
customers of the Company or suppliers to the Company or other third parties who
may have disclosed or entrusted the same to the Company or to the Executive.  7.2           Developments.  (a)           The Executive will make full and
prompt disclosure to the Company of all inventions, creations, improvements,
discoveries, trade secrets, secret processes, technology, know-how,
copyrightable materials, methods, developments, software, and works of
authorship or other creative works, whether patentable or not, which are
created, made, conceived or reduced to practice by him or under his direction
or jointly with others during his employment by the Company, whether or not
during normal working hours or on the premises of the Company (all of which are
collectively referred to in this Agreement as Developments).  13


(b)           The Executive agrees to assign and
does hereby assign to the Company (or any person or entity designated by the
Company) all his right, title and interest in and to all Developments and all
related patents, patent applications, copyrights and copyright
applications.  However, this subsection (b) shall
not apply to Developments that do not relate to any business or research and
development conducted or planned to be conducted by the Company at the time
such Development is created, made, conceived or reduced to practice and that
are made and conceived by the Executive not during normal working hours, not on
the Companys premises and not using the Companys tools, devices, equipment or
Proprietary Information.  The Executive
understands that, to the extent this Agreement shall be construed in accordance
with the laws of any state that precludes a requirement in an employee agreement
to assign certain classes of inventions made by an employee, this subsection (b) shall
be interpreted not to apply to any invention that a court rules and/or the
Company agrees falls within such classes. 
The Executive also hereby waives all claims to moral rights in any
Developments.  (c)           The Executive agrees to cooperate
fully with the Company and to take such further actions as may be necessary or
desirable, both during and after his employment with the Company, with respect
to the procurement, maintenance and enforcement of copyrights, patents and
other intellectual property rights (both in the United States and foreign
countries) relating to Developments.  The
Executive shall sign all papers, including, without limitation, copyright
applications, patent applications, declarations, oaths, formal assignments,
assignments of priority rights and powers of attorney, that the Company may
deem necessary or desirable in order to protect its rights and interests in any
Development.  The Executive further
agrees that if the Company is unable, after reasonable effort, to secure the
signature of the Executive on any such papers, the Chief Executive Officer of
the Company shall be entitled to execute any such  14


papers as the agent and
the attorney-in-fact of the Executive, and the Executive hereby irrevocably
designates and appoints the Chief Executive Officer of the Company as his agent
and attorney-in-fact to execute any such papers on his behalf and to take any
and all actions as the Company may deem necessary or desirable in order to
protect its rights and interests in any Development under the conditions
described in this sentence.  7.3           United States Government
Obligations.  The Executive
acknowledges that the Company from time to time may have agreements with other
parties or with the United States Government, or agencies thereof, which impose
obligations or restrictions on the Company regarding inventions made during the
course of work under such agreements or regarding the confidential nature of
such work.  The Executive agrees to be
bound by all such obligations and restrictions that are made known to the
Executive and to take all action necessary to discharge the obligations of the
Company under such agreements.  7.4           Other Agreements.  The Executive hereby represents that he is
not bound by the terms of any agreement with any previous employer or other
party to refrain from competing, directly or indirectly, with the business of
such previous employer or any other party. 
The Executive further represents that his performance of all the terms
of this Agreement and the performance of his duties as an employee of the
Company does not and will not breach any agreement to keep in confidence
proprietary information, knowledge or data acquired by him in confidence or in
trust prior to his employment with the Company and that the Executive will not
disclose to the Company or induce the Company to use any confidential or
proprietary information, knowledge or material belonging to any previous
employer or others.  The Executive
further represents that his performance of all the terms of this Agreement and
the performance of his duties as an employee of the Company does not and will
not breach any  15


agreement to refrain from
soliciting employees, customers or suppliers of any former employer or others.  8.             Indemnification.  The Company shall indemnify the Executive in
accordance with its Certificate of Incorporation and By-Laws.  9.             Survival.  The provisions of Sections 6, 7 and 8
shall survive the termination of this Agreement for any reason.  10.           Notices.  Any notices delivered under this Agreement
shall be deemed duly delivered three (3) business days after it is sent by
registered or certified mail, return receipt requested, postage prepaid, or one
(1) business day after it is sent for next-business day delivery via a
reputable nationwide overnight courier service, in each case to the address of
the recipient set forth in the introductory paragraph hereto.  Either party may change the address to which
notices are to be delivered by giving notice of such change to the other party
in the manner set forth in this Section 10.  11.           Compliance with Code Section 409A.  This Agreement is intended to comply with the
provisions of Section 409A and the Agreement shall, to the extent
practicable, be construed in accordance therewith.  The Company makes no representation or
warranty and shall have no liability to the Executive or any other person if
any provisions of this Agreement are determined to constitute deferred
compensation subject to Section 409A and do not satisfy an exemption from,
or the conditions of, Section 409A.  12.           Pronouns.  Whenever the context may require, any
pronouns used in this Agreement shall include the corresponding masculine,
feminine or neuter forms, and the singular forms of nouns and pronouns shall
include the plural, and vice versa.  16


13.           Entire Agreement.  This Agreement, together with the ERA,
constitutes the entire agreement between the parties and supersedes all prior
agreements and understandings, whether written or oral, relating to the subject
matter of this Agreement, including, without limitation, the letter agreement
between the Company and the Executive dated March 11, 2003 and the
Original Agreement.  14.           Amendment.  This Agreement may be amended or modified
only by a written instrument executed by both the Company and the Executive.  15.           Governing Law.  This Agreement shall be governed by and
construed in accordance with the laws of the Commonwealth of Massachusetts
(without reference to the conflict of laws provisions thereof).  Any action, suit or other legal proceeding
arising under or relating to any provision of this Agreement shall be commenced
only in a court of the Commonwealth of Massachusetts (or, if appropriate, a
federal court located within the Commonwealth of Massachusetts), and the
Company and the Executive each consents to the jurisdiction of such a court.  The Company and the Executive each hereby
irrevocably waive any right to a trial by jury in any action, suit or other
legal proceeding arising under or relating to any provision of this Agreement
or any other dealing between them relating to the subject matter of this
transaction and the relationship that is being established.  16.           Successors and Assigns.  This Agreement shall be binding upon and
inure to the benefit of both parties and their respective successors and
assigns, including any corporation with which or into which the Company may be
merged or which may succeed to its assets or business; provided, however,
that the obligations of the Executive are personal and shall not be assigned by
him.  17


17.Acknowledgment.  The Executive states and represents that he
has had an opportunity to fully discuss and review the terms of this Agreement
with an attorney.  The Executive further

purpose of the Accrued Vacation Policy is to provide paid time off for
employees to cover vacations and personal time.  2.Accrual rate for
employees at Director level and above  2.1Employees
accrue vacation hours monthly that may be used for paid time off to cover
vacations and personal time. Regular full-time employees, Director level or
above, will accrue vacation time at a rate of ten (10) hours per month
during the first year of employment, for a total of fifteen (15) days per year,
equal to one hundred twenty (120) hours. 
Additional time begins to accrue in the month of the employees
anniversary date, up to a maximum of twenty-three (23) days per year, equal to
one hundred eighty-four (184) hours. Please see schedule below for details on

  15.33  3.Administration  3.1Accrual of vacation
time is pro-rated for employees who are regularly scheduled to work less than
forty (40) hours but work at least twenty (20) hours per week.  For example, an employee with a weekly
schedule of twenty (20) hours will accrue five (5) hours per month, and a
thirty (30) hour employee will accrue seven and a half (7.5) hours of vacation
time per month.


Accrued Vacation Policy: Director Level and
Above  3.Administration
(Continued)  3.2The
current months accrual is accrued on the 15th of every month.  An employee must be employed on the 15th
in order to receive that monthly accrual. 
For example, if an employee is hired on or before the 15th,
they will receive that months accrual, and if they are hired after the 15th,
they will not.  Also, if an employee
terminates employment before the 15th they will not be paid for that
months accrual, but if they terminate after the 15th they will.  3.3Employees
may carry over a maximum of forty (40) accrued vacation hours into the next
calendar year.  The carryover vacation
hours must be used by July 31st of the new calendar year.  Any carried over vacation hours not used by
this date will be forfeited.*  3.3.1*In
accordance with state law, California residents will not have a limit on
carryover time into the next calendar year. 
Once an employee accrues twenty-three (23) days of vacation, equal to
one hundred eighty-four (184) hours, the employee will cease to accrue any
additional vacation time until the vacation balance falls below that
level.  Please refer to Sepracor Human
Resources for more information.  3.4It
is your responsibility to request and schedule the use of accrued vacation time
with your manager.  Approval of vacation
time will depend on the business needs of the organization.  It is your responsibility to accurately track
your use of accrued vacation time through the iTime Tracking system.  3.5At
the minimum, vacation time for full time employees should be taken in four (4) hour
increments, with the norm being eight (8) hour increments. For those with
schedules of 20-39 hours, increments of time used would be pro-rated according
to hours worked.  For example, if you
were regularly scheduled to work six (6) hours, then you would be paid a
six (6) hour vacation day.  3.6Your
manager may approve the borrowing of vacation time, up to a maximum of forty
(40) hours for regular full-time employees and pro-rated accordingly for
regular part-time employees.  Employees
with a negative vacation balance may not borrow additional vacation time until
the existing vacation time balance has been satisfied and then upon approval
from your manager.  Under no circumstances
may an employee borrow vacation time from a future calendar year.  3.7If it has
been verified by Payroll and the manager that an employee has a balance of
accrued and unused vacation time left at the end of employment, the balance
will be converted to cash and included in his/her final paycheck.  In the event an employee ends his/her
employment before having enough accrued time to cover any borrowed vacation
time, the employees final paycheck will reflect a deduction equal to the cash
value of the borrowed vacation time.
