Sample Business Contracts


Employment Agreement - Biopure Corp. and Ronald F. Richards

Employment Forms

  • Employers can customize an employment agreement that states the salary, benefits, working hours and other important provisions for their new or existing employee.
  • Answer simple questions to build a contract with a consultant. Specify the services rendered, when payment is due, as well as IP rights.
  • Employers who compensate their sales employees based on commissions can prepare an agreement to reduce misunderstandings by specifying the base salary and how commissions are calculated.
  • Companies may offer their business executives a contract that is different from the one provided to their regular employees. Executive employment agreements may be more complex because the compensation structure may include a combination of salary and commissions, provide for bonuses based on sales, stock or other financial targets, and include non-compete, confidentiality and severance provisions.
  • Independent sales representatives offer companies the potential to increase the sale of products or services without the burden of increasing headcount. Both parties should understand how commissions are calculated, when commissions will be paid, as well as how the representative will treat confidential information from the company and whether the representative may also sell a competing line of products or services.

with the terms of the Plan. The options shall be or become exercisable, i.e.,
shall vest, in respect of the shares underlying such options as follows:

            1. 30,000 shares     on the Effective Date;

            2. 120,000 shares    5,000 shares per month on the first of each

ability of the Board in its discretion to amend or eliminate any plan or policy
described or referred to in this Section 4, provided, however, that any such
amendment or elimination shall not adversely affect, impair or impact any
outstanding stock-based award held by the Executive as of the date of such
amendment or elimination.

      5. TERMINATION.

      5.1 Death or Disability. The Employment Period shall terminate
automatically upon the Executive's death. If, during the Employment Period, the
Disability (as defined below) of the Executive has occurred, the Company may
give to the Executive written notice of its intention to terminate the
Executive's employment due to such Disability. The Executive's employment with
the Company shall be terminated by the Company on the 30th day after receipt by
the Executive of such notice (the "Disability Effective Date"), if, within such
thirty (30) day period, the Executive shall not have returned to full-time
performance of the Executive's duties. For purposes of this Agreement,
"Disability" means a physical or mental disability resulting in the inability of
the Executive to substantially perform his duties full-time under this
Agreement, as set forth in Section 3, during any consecutive six-month period,
as determined by a licensed physician mutually selected by the Company and the
Executive or his legal representative. If the Company and the Executive cannot
agree as to the selection of a licensed physician for purposes of making such
determination, then each party shall select a licensed physician and these two
licensed physicians shall select a third licensed physician who shall make such
determination. Nothing in this Section 5.1 is intended to be inconsistent with
or in any way alter the parties' responsibilities under applicable federal or
state law regarding disabilities, if any.

      5.2 Cause.

            (a) The Board may terminate the employment of the Executive for
Cause by written notice to the Executive. Upon receipt of such written notice,
the Executive shall have the right to seek (within ten (10) business days) an
opportunity to be heard by the Board, which opportunity the Board shall arrange
as promptly and in such format as directors' schedules permit. For purposes of
this Agreement, "Cause" shall mean (a) an act or acts of material personal
dishonesty taken by, or committed at the request of, Executive, intended to
result in the personal enrichment of the Executive at the expense of the
Company, or any of its Affiliates, (b) repeated willful violations by Executive
of the material terms of this Agreement,


                                      -4-
<PAGE>

which have not been cured within thirty (30) days after written notice has been
given by the Board to the Executive, or (c) the conviction of Executive of a
felony.

            (b) In the event the Board wishes to terminate the Executive for
breach of this Agreement pursuant to Section 5.2(a), and such breach is capable
of being cured, the Board shall provide the Executive with written notice
specifying in reasonable detail the services or matters which it contends the
Executive has not adequately performed, or the material provisions of this
Agreement of which the Executive is in violation and the acts constituting such
violation, why the Company has Cause to terminate this Agreement and what the
Executive should do to adequately perform his obligations hereunder along with a
copy of a resolution, duly adopted by the Board at a meeting called and held for
the purpose (after reasonable notice to Executive and an opportunity for him to
be heard before the Board), finding that Executive is in default hereunder. If
within ten (10) days of receipt of the notice, the Board reasonably believes
that the Executive has performed the required services or has modified his
performance to correct the matters complained of, the Executive's breach will be
deemed cured, and the Executive shall not be terminated. However, if the nature
of the service not performed by the Executive or the matters complained of are
such that more than ten (10) days are reasonably required to perform the
required service or to correct the matters complained of, then his breach will
be deemed cured if the Executive commences to perform such service or to correct
such matters within the ten (10) day period and thereafter diligently prosecutes
such performance or correction to completion in a time frame established by the
Board, in its reasonable judgment. If the Executive does not perform the
required services or modify his performance to correct the matter complained of
within the ten (10) day period or the Board-approved extension thereof, the
Board shall have the right to terminate this Agreement at the end of the ten
(10) day period or extension thereof. If the Board, in its reasonable judgment,
determines that the Executive's breach of this Agreement pursuant to Section
5.2(a) is not capable of being cured, and in the event of any breach of Section
8 or of any of Sections 1 through 5 of the Protection of Company Property
Agreement (defined in Section 8), the Board may terminate the Executive
immediately for Cause by written notice to the Executive.

      5.3 Without Cause. During the Employment Period, upon written notice given
to the Executive, the Board may terminate the Executive's employment hereunder
other than for Cause.

      5.4 Termination by Executive for Good Reason. During the Employment
Period, the Executive may terminate his employment hereunder by written notice
for Good Reason. For purposes of this Agreement, "Good Reason" shall mean: (a)
the reduction of the Executive's Base Salary or target bonus opportunity without
the Executive's prior written consent; (b) the diminution, without his consent,
of the Executive's title, authority, duties or responsibilities as specified in
Section 3, or the assignment of duties and responsibilities that are
inconsistent with his positions as Chief Financial Officer and Senior Vice
President, Business Development of the Company, or if the Executive reports to
anyone other than the Chief Executive Officer and the Board; (c) the Company
requiring the Executive, without his consent, to be based in any office or
location other than the Company's headquarters office, and such headquarters
shall not be located during the Employment Period outside of a 30-mile radius of
Cambridge; (d) the material breach by the Company of any provision of this
Agreement which has not been cured within thirty (30) days after a notice of
termination has been given by the


                                      -5-
<PAGE>

Executive to the Company; (e) a request by the Chief Executive Officer or the
Board that the Executive engage in activities that would result in materially
misleading or inaccurate financial reporting by the Company under generally
accepted accounting principles or (f) failure of the Company to obtain the
assumption in writing of its obligations under this Agreement as a condition
precedent of such succession.

      5.5 Termination by Executive Without Good Reason. During the Employment
Period the Executive may terminate employment hereunder by written notice
without Good Reason, and such termination shall not be deemed to be a breach of
this Agreement.

      5.6 Date of Termination. "Date of Termination" shall mean:

            (a) if the Executive's employment is terminated by the Company,
other than for Cause or Disability, the Date of Termination shall be the date on
which the Company notifies the Executive in writing of such termination under
Section 5.3;

            (b) if the Executive's employment is terminated by the Company for
Cause, the Date of Termination shall be at the end of the 10-day period or any
extension given under Section 5.2;

            (c) if the Executive's employment is terminated by the Executive,
the date of termination shall be the date on which the Executive notifies the
Company of such termination (or the date on which the Company otherwise first
learns of such termination);

            (d) if the Executive's employment is terminated by reason of death
or Disability, the Date of Termination shall be the date of death of the
Executive or the Disability Effective Date, as the case may be.

      6. OBLIGATIONS OF THE COMPANY UPON TERMINATION.

      6.1 Cause, Death, Disability or Voluntarily by the Executive. If the
Executive's employment is terminated by reason of the Executive's death, the
Executive's Disability, for Cause by the Company or by the Executive voluntarily
(other than for Good Reason), the Executive, or the Executive's legal
representative, as the case may be, shall be entitled to receive (a) the
Executive's Base Salary through the Date of Termination; (b) any compensation
previously deferred by the Executive (together with any accrued interest thereon
through the Date of Termination) and not yet paid by the Company, and any bonus
earned in the previous year and not yet paid by the Company; (c) any accrued
vacation pay through the Date of Termination not yet paid by the Company; and
(d) a pro rata bonus for the year of termination calculated and payable after
year-end, if any, provided, however that no such pro rata bonus shall be paid to
the Executive if his employment is terminated for Cause or voluntarily by the
Executive without Good Reason (such amounts specified in clauses (a), (b), (c)
and (d) are hereinafter referred to as the "Accrued Obligations"). Accrued
Obligations shall not include other compensation not described in the preceding
sentence accrued but not yet paid through the Date of Termination. All such
Accrued Obligations except for that specified in clause (d) shall be paid to the
Executive or to the Executive's estate or beneficiary, as applicable, in a lump
sum in cash within thirty (30) days after the Date of Termination or as
otherwise provided by law,


                                      -6-
<PAGE>

whichever occurs first. In addition to the foregoing, if the Executive's
employment is terminated by reason of the Executive's death or Disability,
unvested options granted to the Executive during his employment shall
immediately vest and remain exercisable for one (1) year from the Date of
Termination. In the case of death, the Executive's family shall be entitled to
receive any family death benefits provided by the Company to surviving families
of senior executives. In the case of the Executive's Disability, the Executive
shall be entitled as of the Disability Effective Date to receive the disability
benefits provided by the Company to disabled senior executives.

      6.2 Other Than for Cause, Death or Disability, or by the Executive for
Good Reason. If, during the Employment Period, the Company terminates the
Executive's employment (other than for Cause, death or Disability) or the
Executive terminates his employment for Good Reason, the Executive shall be
entitled to receive, within thirty (30) days after the Date of Termination, the
following:

            (a) The Company shall pay to the Executive all Accrued Obligations.

            (b) The Company shall pay to the Executive in cash a lump sum amount
equal to the Executive's then current Base Salary for one year, provided,
however, that if the Executive's employment terminates other than for Cause,
death or Disability or if the Executive terminates his employment for Good
Reason during the 2-year period beginning on the date of a Change in Control (as
defined in the Company's 2002 Omnibus Securities and Incentive Plan), then the
Executive shall receive a lump sum payment equal to 200% of the Executive's then
current Base Salary.

            (c) The Company shall pay its proportionate share of the cost of the
Executive's COBRA continuation coverage for a period of 12 months or 24 months
if the Executive's employment terminates during the 2-year period beginning on
the date of Change in Control (as defined in the Plan).

            (d) All unvested options granted to the Executive during his
employment shall immediately vest and remain exercisable for ninety (90) days
from the Date of Termination.

            (e) The parties recognize and agree that, if the Company terminates
the Executive's employment during the Employment Period other than for Cause,
death or Disability or if the Executive terminates his employment during the
Employment Period for Good Reason, the actual damages to the Executive would be
difficult if not impossible to ascertain and agree that the Executive shall be
paid in accordance with the provisions of this Section 6.2. The Executive shall
not be required to mitigate the amount of any payment provided for in this
Section 6.2 by seeking other employment or otherwise, nor shall any compensation
earned by the Executive in other employment or otherwise reduce the amount of
any payment provided for in this Section 6.2.

      6.3 Full Satisfaction. The payments actually received, accepted and
retained by the Executive (or his legal representatives) under this Agreement
that are attributable to the termination of the Executive's employment shall be
in full and complete satisfaction of any and all claims the Executive (or his
legal representatives) may have against the Company which are


                                      -7-
<PAGE>

in any way related to the employment relationship (including the Executive's
hiring) between the Executive and the Company or the termination of that
relationship.

      6.4 Other Payments. Notwithstanding anything to the contrary contained
herein (including without limitation Section 6.3), any compensation or benefits,
if any, which are vested in the Executive or which the Executive is otherwise
entitled to receive under any plan, program or arrangement of the Company
before, at or subsequent to the Date of Termination shall be payable in
accordance with the terms and provisions of such plan, program or arrangement.
Any incentive, savings, retirement, or welfare or fringe benefit plan or program
may be changed by the Company in its discretion, provided, however, that such
change shall not adversely affect, impair or impact the Executive (unless such
change is broad-based and applies to all current and former employees of the
Company).

      7. TAXES. The Company may withhold from any amounts payable under this
Agreement such federal, state or local taxes or other withholdings as shall be
required or permitted to be withheld pursuant to any applicable law or
regulation, the operation of any incentive, savings, retirement, or welfare or
fringe benefit plan, or by written agreement with the Executive. In addition, if
any payment to the Executive would trigger "golden parachute" excise taxes
pursuant to Section 4999 of the Internal Revenue Code of 1986, as amended (the
"Code"), or any successor provision, a gross-up payment will be provided in an
amount sufficient to make the Executive whole for applicable excise taxes and
all income, employment, additional excise taxes or any interest or penalties
with respect to such gross-up payment (the "Gross-Up Payment"). All
determinations concerning whether a Gross-Up Payment is due to the Executive and
the amount of such Gross-Up Payment will be made by a nationally recognized
certified public accounting firm (the "Accounting Firm") selected by the Company
and subject to the approval of the Executive, such approval not to be
unreasonably withheld. If the Accounting Firm determines that any Gross-Up
Payment is due to the Executive, the Company shall pay the required Gross-Up
Payment to the Executive or on the Executive's behalf within ten (10) business
days after receipt of such determination and calculations. If the Accounting
Firm determines that no "golden parachute" excise taxes would be triggered, it
will, at the same time as it makes such determination, furnish the Executive
with an opinion that the Executive has substantial authority not to report any
excise tax on the Executive's federal, state, local income or other tax return.
Any determination by the Accounting Firm as to the amount of the Gross-Up
Payment will be binding upon the Company and the Executive.

      8. CONFIDENTIAL INFORMATION. The Executive shall execute and deliver to
the Company on or prior to the Effective Date an Employee Agreement Concerning
Protection of Company Property and the Arbitration of Legal Disputes
("Protection of Company Property Agreement") in the form attached hereto, the
terms of which are incorporated herein by reference; provided, however, that to
the extent that a term or provision of this Agreement conflicts with any term or
provision of the Protection of Company Property Agreement, such term or
provision of this Agreement shall prevail over such term or provision of the
Protection of Company Property Agreement..

      9. INDEMNIFICATION.


                                      -8-
<PAGE>

            (a) During the Employment Period, the Company agrees that if the
Executive is made a party, or is threatened to be made a party, to any action,
suit or proceeding, whether civil, criminal, administrative or investigative (a
"Proceeding"), by reason of the fact that he is or was a director, officer or
employee of the Company or is or was serving at the request of the Company as a
director, officer, member, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, including service with
respect to employee benefit plans, whether or not the basis of such Proceeding
is the Executive's alleged action in an official capacity while serving as a
director, officer, member, employee or agent, the Executive shall be indemnified
and held harmless by the Company to the fullest extent legally permitted or
authorized by the Company's certificate of incorporation or bylaws or
resolutions of the Board or, if greater, by the laws of the State of Delaware,
against all cost, expense, liability and loss (including, without limitation,
attorney's fees, judgments, fines, ERISA excise taxes or penalties and amounts
paid or to be paid in settlement) reasonably incurred or suffered by the
Executive in connection therewith, and such indemnification shall continue as to
the Executive even if he has ceased to be a director, member, employee or agent
of the Company or other entity and shall inure to the benefit of the Executive's
heirs, executors and administrators. The Company shall advance to the Executive
all reasonable costs and expenses incurred by him in connection with a
Proceeding within 20 days after receipt by the Company of a written request for
such advance. Such request shall include an undertaking by the Executive to
repay the amount of such advance if it shall ultimately be determined in a final
judgment by a court (not subject to further appeal) that he is not entitled to
be indemnified against such costs and expenses.

            (b) Neither the failure of the Company (including its Board,
independent legal counsel or stockholders) to have made a determination prior to
the commencement of any proceeding concerning payment of amounts claimed by the
Executive under Section 9(a) that indemnification of the Executive is proper
because he has met the applicable standard of conduct, nor a determination by
the Company (including its Board, independent legal counsel or stockholders)
that the Executive has not met such applicable standard of conduct, shall create
a presumption that the Executive has not met the applicable standard of conduct.

            (c) The Company agrees to continue and maintain a directors and
officers' liability insurance policy covering the Executive to the extent the
Company provides such coverage for its other executive officers.

            (d) If, at any time after the termination of this Agreement and any
associated severance period, the Executive is requested by the Company, or is
required, to testify or to provide evidence or otherwise to perform services in
relation to litigation or similar proceedings (civil, administrative, arbitral
or otherwise) in which the Company is a named party or is otherwise involved the
Company shall pay Executive: (i) with respect to each day that Executive appears
as a witness or is deposed, the sum of $2,000 per day or portion thereof and
(ii) with respect to each day that Executive is involved in the preparation
therefor, the sum of $1,000 per day or portion thereof. Notwithstanding the
foregoing, any time after the termination of this Agreement, the Company shall
reimburse Executive for reasonable travel and accommodation expenses if such
services are required to be performed outside of the city of Executive's
domicile.


                                      -9-

      10. SURVIVAL. The Executive agrees that Sections 8 and 9 of this Agreement
shall survive the termination of (a) this Agreement, (b) the Employment Period
and/or (c) the Executive's employment with the Company.

      11. SUCCESSORS. This Agreement is personal to the Executive and may not be
assigned by the Executive. This Agreement shall inure to the benefit of, and be
enforceable by, the Executive and the Executive's legal representatives, as
applicable. This Agreement shall inure to the benefit of and be binding upon the
