Exhibit 10.16

EMPLOYMENT AGREEMENT


MICHAEL D. KAISER


This Employment Agreement (this "Agreement"), is made and entered into as of 
the 28th day of September, 1998 (the "Effective Date"), by and 
between Corporate Realty Management, LLC., a Maryland LLC (the "Employer"), 
and Corporate Office Management Inc. ("COMI"), a subsidiary of Corporate 
Office Properties Trust ("COPT"), and Michael D. Kaiser (the "Executive").

RECITALS

A. The Employer desires to employ the Executive as an officer of the Employer 
for a specified term, and the Executive is willing to accept such employment 
upon the terms and conditions hereinafter set forth.

B. The Employer recognizes that circumstances may arise in which a change of 
control of the Employer, through acquisition or otherwise, may occur, thereby 
causing uncertainty of employment without regard to the competence or past 
contributions of the Executive, and that such uncertainty may result in the 
loss of valuable services of the Executive.  Accordingly, the Employer and 
the Executive wish to provide reasonable security to the Executive against 
changes in the employment relationship in the event of any such change of 
control.

NOW, THEREFORE, in consideration of the premises and of the covenants and 
agreements hereinafter contained, it is covenanted and agreed by and between 
the parties hereto as follows:

accountants, with regard to any question concerning the amount or requirement 
of any such withholding.

                                       2
 

3.   TERM AND TERMINATION.

(a) BASIC TERM.  The Executive's employment hereunder shall be for a 
continuous and self-renewing two (2) year term, commencing as of the 
Effective Date, unless terminated by either party, with or without cause, 
effective as of the first (1st) business day after written notice to that 
effect is delivered to the other party.

(b) PREMATURE TERMINATION.

(i) In the event of the termination of the employment of the Executive under 
this Agreement by the Employer for any reason other than expiration of the 
term hereof or a "for-cause" termination in accordance with the provisions of 
paragraph (d) of this Section 3, then notwithstanding any actual or allegedly 
available alternative employment or other mitigation of damages by or 
available to the Executive, the Executive shall be entitled to a "Lump Sum 
Payment" equal to the sum of:  (w) his monthly Base Salary then payable, 
multiplied by the remaining number of months or partial months until 
expiration of the Basic Term or renewal term, if any, (but not less than 18 
months), and an annualized and proportional amount equal to the average of 
the two (2) most recent annual Performance Bonuses that the Executive 
received; For purposes of calculating the Lump Sum Payment amounts due, the 
Executive's employment with the Employer shall be agreed to have commenced on 
October 1, 1998.  In the event of a termination governed by this subparagraph 
(b)(i) of Section 3, the Employer shall also:  (y) notwithstanding the 
vesting schedule otherwise applicable, fully vest all of Executive's options 
outstanding under any option or stock incentive plan herein after established 
by Employer ("Option Plan") and allow a period of eighteen (18) months 
following the termination of employment for the Executive to exercise any 
such options; and (z) continue for the Executive (provided that such items 
are not available to him by virtue of other employment secured after 
termination) the perquisites, plans and benefits provided under the 
Employer's Perquisite Policy and Benefit Plans as of and after the date of 
termination, [all items in (z) being collectively referred to as 
"Post-Termination Perquisites and Benefits"], for the lesser of the number of 
full months the Executive has theretofore been employed by the Employer (but 
not less than twelve (12) months)or eighteen (18) months following such 
termination.  The payments and benefits provided under (w), (x), (y) and (z) 
above by the Employer shall not be offset against or diminish any other 
compensation or benefits accrued as of the date of termination.

(ii) Payment to the Executive under this Section 3(b) will be made monthly 
over twelve (12) months, unless mutually agreed by the parties to minimize 
the Executives' tax burden in any year.

(c) CONSTRUCTIVE TERMINATION.  If at any time during the term of this 
Agreement, except in connection with a "for-cause" termination pursuant to 
paragraph (d) of this Section 3, the Executive is Constructively Discharged 
(as hereinafter defined), then the Executive shall have the right, by written 
notice to the Employer given within one hundred and twenty (120) days of such 
Constructive Discharge, to terminate his services hereunder, effective as of 
thirty (30) days after such notice, and the Executive shall have no rights or 
obligations under this Agreement other than as provided in Section 5 hereof. 
The Executive shall in such event be entitled to a Lump Sum Payment of Base 
Salary and Performance Bonus compensation as well as all of the 
Post-Termination Prerequisites and Benefits, as if such termination of his 
employment had been effectuated pursuant to paragraph (b) of this Section 3.

For purposes of this Agreement, the Executive shall be deemed to have been 
"Constructively Discharged" upon the occurrence of any one of the following 
events:

(i) The Executive is not re-elected to, or is removed from, the position with 
the Employer set forth in Section 1 hereof, other than as a result of the 
Executive's election or appointment to positions of equal or superior scope 
and responsibility; or

(ii) The Executive shall fail to be vested by the Employer with the powers,
authority and support services normally attendant to any of said offices; or

                                       3

Executive will be terminated or materially modified in the future or that the 
Executive will be Constructively Discharged in the future; or

(iv) The Employer changes the primary employment location of the Executive to 
a place that is more than fifty (50) miles from the primary employment 
location, 8815 Centre Park Drive, Columbia Maryland 21045, as of the 
Effective Date of this Agreement; or

(v) The Employer otherwise commits a material breach of its obligations under 
this Agreement.

(vi) The Employer seeks protection under U.S. Bankruptcy codes.

(d) TERMINATION FOR CAUSE.  The employment of the Executive and this 
Agreement may be terminated "for-cause" as hereinafter defined.  Termination 
"for-cause" shall mean the termination of employment on the basis or as a 
result of:  (i) the Executive's death or his permanent disability, which 
latter term shall mean the Executive's inability, as a result of physical or 
mental incapacity, substantially to perform his duties hereunder for a period 
of either six (6) consecutive months, or one hundred and twenty (120) 
business days within a consecutive twelve (12) month period; (ii) a material 
violation by the Executive of any applicable material law or regulation 
respecting the business of the Employer; (iii) the Executive being found 
guilty of, or being publicly associated with, to the Employer's detriment, a 
felony or an act of dishonesty in connection with the performance of his 
duties as an officer of the Employer, or the Executive's commission of an act 
which in the opinion of a reasonable third party disqualifies the Executive 
from serving as an officer or director of the Employer; or (iv) the willful 
or negligent failure of the Executive to perform his duties hereunder in any 
material respect.  The Executive shall be entitled to at least thirty (30) 
days' prior written notice of the Employer's intention to terminate his 
employment for any cause (except the Executive's death), specifying the 
grounds for such termination, affording the Executive a reasonable 
opportunity to cure any conduct or act (if curable) alleged as grounds for 
such termination, and a reasonable opportunity to present to the Board his 
position regarding any dispute relating to the existence of such cause.

(e) TERMINATION UPON DEATH.  In the event payments are due and owing under 
this Agreement at the death of the Executive, such payments shall be made to 
such beneficiary, designee or fiduciary as Executive may have designated in 
writing, or failing such designation, to the executor or administrator of his 
estate, in full settlement and satisfaction of all claims and demands on 
behalf of the Executive.  Such payments shall be in addition to any other 
death benefits of the Employer made available for the benefit of the 
Executive, and in full settlement and satisfaction of all payments provided 
for in this Agreement.

(f) TERMINATION UPON DISABILITY.  The Employer may terminate the Executive's 
employment after the Executive is determined to be disabled under the current 
Employer program or by a physician engaged by the Employer and reasonably 
approved by the Executive.  In the event of a dispute regarding the 
Executive's "disability," such dispute shall be resolved through arbitration 
as provided in paragraph (d) of Section 9 hereof, except that the arbitrator 
appointed by the American Arbitration Association shall be a duly licensed 
medical doctor.  The Executive shall be entitled to the compensation and 
benefits provided for under this Agreement during any period of 
incapacitation occurring during the term of this Agreement, and occurring 
prior to the establishment of the Executive's "disability" during which the 
Executive is unable to work due to a physical or mental infirmity.  
Notwithstanding anything contained in this Agreement to the contrary, until 
the date specified in a notice of termination relating to the Executive's 
disability, the Executive shall be entitled to return to his positions with 
the Employer as set forth in this Agreement, in which event no disability of 
the Executive will be deemed to have occurred.

                                       4


(g) TERMINATION UPON CHANGE OF CONTROL.

(i) In the event of a Change in Control (as defined below) of the Employer 
and the termination of the Executive's employment by Executive or by the 
Employer under either 1 or 2 below, the Executive shall, be entitled to a 
Lump Sum Payment equal to the sum of:  (w) his monthly Base Salary then 
payable, multiplied by twenty-four (24); plus (x) two (2) times the average 
of the two (2) most recent annual Performance Bonuses that the Executive 
received; provided, however, that if the Executive has been employed by the 
Employer for fewer than two (2) years, then the amount set forth in (x) above 
shall be equal to two (2) times the average of the annual Performance Bonuses 
that the Executive has theretofore received from the Employer.  The Employer 
shall also: (y) notwithstanding the vesting schedule otherwise applicable, 
fully vest all of Executive's options outstanding under any Option Plan and 
allow a period of eighteen (18) months following the termination of 
employment of the Executive for the Executive's exercise of such options; and 
(z) continue for the Executive (provided that such items are not available to 
him by virtue of other employment secured after termination) all of the 
perquisites, plans and benefits provided under paragraph (c) of Section 2, 
for 18 months following such termination. The payments and benefits provided 
under (w), (x), (y) and (z) above by the Employer shall not be offset against 
or diminish any other compensation or benefits accrued as of the date of 
termination. The following shall constitute termination under this paragraph:

1.   The Executive terminates his employment under this Agreement pursuant to 
a written notice to that effect delivered to the Board within six (6) months 
after the occurrence of the Change in Control.

2.   Executive's employment is terminated, including Constructively 
Discharged, by the Employer or its successor either in contemplation of or 
after Change in Control, other than on a for-cause basis.

(ii) For purposes of this paragraph, the term "Change in Control" shall mean 
the following occurring after the date of this Agreement:

1.   The consummation of the acquisition by any person (as such term is 
defined in Section 13(d) or 14(d) of the Securities Exchange Act of 1934, as 
amended (the "1934 Act") of beneficial ownership (within the meaning of Rule 
13d-3 promulgated under the 1934 Act) of forty percent (40%) or more of the 
combined voting power embodied in the then-outstanding voting securities of 
COPT or the Employer; or

2.   Approval by the stockholders of the Employer of:  (1) a merger or 
consolidation of the Employer, if the stockholders of COPT or the Employer 
immediately before such merger or consolidation do not, as a result of such 
merger or consolidation, own, directly or indirectly, more than fifty percent 
(50%) of the combined voting power of the then outstanding voting securities 
of the entity resulting from such merger or consolidation in substantially 
the same proportion as was represented by their ownership of the combined 
voting power of the voting securities of COPT or the Employer outstanding 
immediately before such merger or consolidation; or (2) a complete or 
substantial liquidation or dissolution, or an agreement for the sale or other 
disposition, of all or substantially all of the assets of COPT or the 
Employer.

Notwithstanding the foregoing, a Change in Control shall not be deemed to 
occur solely because forty percent (40%) or more of the combined voting 
then-outstanding securities is acquired by:  (1) a trustee or other fiduciary 
holding securities under one or more employee benefit plans maintained for 
employees of the entity; or (2) any corporation or other entity which, 
immediately prior to such acquisition, is owned directly or in directly the 
stockholders of the Employer in the same proportion as their ownership of 
stock in COPT or the Employer immediately prior to such acquisition.

(ii) If it is determined, in the opinion of the Employer's independent 
accountants, in consultation with the Employer's independent counsel, that any
amount payable to the Executive by the Employer under this Agreement, or any 
other plan or agreement under which the Executive participates or is a party, 
would 

                                       5


constitute an "Excess Parachute Payment" within the meaning of Section 280G 
of the Internal Revenue Code of 1986, as amended (the "Code") and be subject 
to the excise tax imposed by Section 4999 of the Code (the "Excise Tax"), the 
Employer shall pay to the Executive a "grossing-up" amount equal to the 
amount of such Excise Tax and all federal and state income or other taxes 
with respect payment of the amount of such Excise Tax, including all such 
taxes with respect to any such grossing-up amount.  If at a later date, the 
Internal Revenue Service assesses a deficiency against the Executive for the 
Excise Tax which is greater than that which was determined at the time such 
amounts were paid, the Employer shall pay to the Executive the amount of such 
unreimbursed Excise Tax plus any interest, penalties and professional fees or 
expenses, incurred by the Executive as a result of such assessment, including 
all such taxes with respect to any such additional amount.  The highest 
marginal tax rate applicable to individuals at the time of payment of such 
amounts will be used for purposes of determining the federal and state income 
and other taxes with respect thereto.  The Employer shall withhold from any 
amounts paid under this Agreement the amount of any Excise Tax or other 
federal, state or local taxes then required to be withheld. Computations of 
the amount of any grossing-up supplemental compensation paid under this 
subparagraph shall be made by the Employer's independent accountants, in 
consultation with the Employer's independent legal counsel.  The Employer 
shall pay all accountant and legal counsel fees and expenses.

4.   CONFIDENTIALITY AND LOYALTY.  The Executive acknowledges that heretofore 
or hereafter during the course of his employment he has produced and 
received, and may hereafter produce, receive and otherwise have access to 
various materials, records, data, trade secrets and information not generally 
available to the public (collectively, "Confidential Information") regarding 
the Employer and its subsidiaries and affiliates.  Accordingly, during and 
subsequent to termination of this Agreement, the Executive shall hold in 
confidence and not directly or indirectly disclose, use, copy or make lists 
of any such Confidential Information, except to the extent that such 
information is or thereafter becomes lawfully available from public sources, 
or such disclosure is authorized in writing by the Employer, required by law 
or by any competent administrative agency or judicial authority, or otherwise 
as reasonably necessary or appropriate in connection with the performance by 
the Executive of his duties hereunder.  All records, files, documents, 
computer diskettes, computer programs and other computer-generated material, 
as well as all other materials or copies thereof relating to the Employer's 
business, which the Executive shall prepare or use, shall be and remain the 
sole property of the Employer, shall not be removed from the Employer's 
premises without its written consent, and shall be promptly returned to the 
Employer upon termination of the Executive's employment hereunder.  The 
Executive agrees to abide by the Employer's reasonable policies, as in effect 
from time to time, respecting confidentiality and the avoidance of interests 
conflicting with those of the Employer.

5.   NON-COMPETITION COVENANT.

(a) RESTRICTIVE COVENANT.  The Employer and the Executive have jointly reviewed
the tenant lists, property submittals, logs, broker lists, and operations of 
the Employer, and have agreed that as an essential ingredient of and in 
consideration of this Agreement and the payment of the amounts described in 
Sections 2 and 3 hereof, the Executive hereby agrees that, except with the 
express prior written consent of the Employer, for a period equal to the 
lesser of the number of full months the Executive has at any time been 
employed by the Employer or  twenty-four (24) months after the termination of 
the Executive's employment with the Employer (the "Restrictive Period"), he 
will not directly or indirectly compete with the then existing business of 
the Employer, including, but not by way of limitation, by directly or 
indirectly owning, managing, operating, controlling, financing, or by 
directly or indirectly serving as an employee, officer or director of or 
consultant to, or by soliciting or inducing, or attempting to solicit or 
induce, any employee or agent of Employer to terminate employment with 
Employer and become employed by any person, firm, partnership, corporation, 
trust or other entity which owns or operates a business similar to that of 
the Employer (the "Restrictive Covenant").  For purposes of this subparagraph 
(a), a business shall be considered "similar" to that of the Employer if it 
is engaged in the acquisition, development, ownership, operation, management 
or leasing of suburban office property (i) in any geographic market or 
submarket in which the Employer owns more than 750,000 s.f. of properties 

                                        6


either as of the date hereof or as of the date of termination of the 
Executive's employment.  However, it is expressly understood that this 
restriction shall apply only to the operations of the Employer as of the date 
of termination of this agreement.  If the Executive violates the Restrictive 
Covenant and the Employer brings legal action for injunctive or other relief, 
the Employer shall not, as a result of the time involved in obtaining such 
relief, be deprived of the benefit of the full period of the Restrictive 
Covenant. Accordingly, the Restrictive Covenant shall be deemed to have the 
duration specified in this paragraph (a) computed from the date the relief is 
granted but reduced by the time between the period when the Restrictive 
Period began to run and the date of the first violation of the Restrictive 
Covenant by the Executive.  In the event that a successor of the Employer 
assumes and agrees to perform this Agreement or otherwise acquires the 
Employer, this Restrictive Covenant shall continue to apply only to the 
primary service area of the Employer as it existed immediately before such 
assumption or acquisition and shall not apply to any of the successor's other 
offices or markets.  The foregoing Restrictive Covenant shall not prohibit 
the Executive from owning, directly or indirectly, capital stock or similar 
securities which are listed on a securities exchange or quoted on the 
National Association of Securities Dealers Automated Quotation System which 
do not represent more than five percent (5%) of the outstanding capital stock 
of any corporation.  

(b) REMEDIES FOR BREACH OF RESTRICTIVE COVENANT.  The Executive acknowledges 
that the restrictions contained in Sections 4 and 5 of this Agreement are 
reasonable and necessary for the protection of the legitimate proprietary 
business interests of the Employer; that any violation of these restrictions 
would cause substantial injury to the Employer and such interests; that the 
Employer would not have entered into this Agreement with the Executive 
without receiving the additional consideration offered by the Executive in 
binding himself to these restrictions; and that such restrictions were a 
material inducement to the Employer to enter into this Agreement.  In the 
event of any violation or threatened violation of these restrictions, the 
Employer shall be relieved of any further obligations under this Agreement, 
shall be entitled to any rights, remedies or damages available at law, in 
equity or otherwise under this Agreement, and shall be entitled to 
preliminary and temporary injunctive relief granted by a court of competent 
jurisdiction to prevent or restrain any such violation by the Executive and 
any and all persons directly or indirectly acting for or with him, as the 
case may be, while awaiting the decision of the arbitrator selected in 
accordance with paragraph (d) of Section 9 of this Agreement, which decision, 
if rendered adverse to the Executive, may include permanent injunctive relief 
to be granted by the court.  

6.   INTERCORPORATE TRANSFERS.  If the Executive shall be voluntarily 
transferred to an affiliate of the Employer, such transfer shall not be 
deemed to terminate or modify this Agreement, and the employing corporation 
to which the Executive shall have been transferred shall, for all purposes of 
this Agreement, be construed as standing in the same place and stead as the 
Employer as of the date of such transfer.  For purposes hereof, an affiliate 
of the Employer shall mean any corporation or other entity directly or 
indirectly controlling, controlled by, or under common control with the 
Employer.  The Employer shall be secondarily liable to the Executive for the 
obligations hereunder in the event the affiliate of the Employer cannot or 
refuses to honor such obligations.  For all relevant purposes hereof, the 
tenure of the Executive shall be deemed to include the aggregate term of his 
employment by the Employer or its affiliate.

7.   INTEREST IN ASSETS.  Neither the Executive nor his estate shall acquire 
hereunder any rights in funds or assets of the Employer, otherwise than by 
and through the actual payment of amounts payable hereunder; nor shall the 
Executive or his estate have any power to transfer, assign (except into a 
trust for purposes of estate planning), anticipate, hypothecate or otherwise 
encumber in advance any of said payments; nor shall any of such payments be 
subject to seizure for the payment of any debt, judgment, alimony, separate 
maintenance or be transferable by operation of law in the event of 
bankruptcy, insolvency or otherwise of the Executive.

8.   INDEMNIFICATION. 

(a) The Employer shall provide the Executive (including his heirs, personal 
representatives, executors and 

                                       7


administrators), during the term of this Agreement and thereafter throughout 
all applicable limitations periods, with coverage under the Employer's 
then-current directors' and officers' liability insurance policy, at the 
Employer's expense.

(b) In addition to the insurance coverage provided for in paragraph (a) of 
this Section 8, the Employer shall defend, hold harmless and indemnify the 
Executive (and his heirs, executors and administrators) to the fullest extent 
permitted under applicable law, and subject to the requirements, limitations 
and specifications set forth in the Bylaws and other organizational documents 
of the Employer, against all expenses and liabilities reasonably incurred by 
him in connection with or arising out of any action, suit or proceeding in 
which he may be involved by reason of his having been an officer of the 
Employer (whether or not he continues to be an officer at the time of 
incurring such expenses or liabilities), such expenses and liabilities to 
include, but not be limited to, judgments, court costs and attorneys' fees 
and the cost of reasonable settlements.

(c) In the event the Executive becomes a party, or is threatened to be made a 
party, to any action, suit or proceeding for which the Employer has agreed to 
provide insurance coverage or indemnification under this Section 8, the 
Employer shall, to the full extent permitted under applicable law, advance 
all expenses (including the reasonable attorneys' fees of the attorneys 
selected by Employer and approved by Executive for the representation of the 
Executive), judgments, fines and amounts paid in settlement (collectively 
"Expenses") incurred by the Executive in connection with the investigation, 
defense, settlement, or appeal of any threatened, pending or completed 
action, suit or proceeding, subject to receipt by the Employer of a written 
undertaking from the Executive covenanting: (i) to reimburse the Employer for 
all Expenses actually paid by the Employer to or on behalf of the Executive 
in the event it shall be ultimately determined that the Executive is not 
entitled to indemnification by the Employer for such Expenses; and (ii) to 
assign to the Employer all rights of the Executive to insurance proceeds, 
under any policy of directors' and officers' liability insurance or 
otherwise, to the extent of the amount of Expenses actually paid by the 
Employer to or on behalf of the Executive.

9.   GENERAL PROVISIONS.

(a) SUCCESSORS; ASSIGNMENT.  This Agreement shall be binding upon and inure to
the benefit of the Executive, the Employer and his and its respective 
personal representatives, successors and assigns, and any successor or assign 
of the Employer shall be deemed the "Employer" hereunder.  The Employer shall 
require any successor to all or substantially all of the business and/or 
assets of the Employer, whether directly or indirectly, by purchase, merger, 
consolidation, acquisition of stock, or otherwise, by an agreement in form 
and substance satisfactory to the Executive, expressly to assume and agree to 
perform this Agreement in the same manner and to the same extent as the 
Employer would be required to perform if no such succession had taken place.

(b) ENTIRE AGREEMENT; MODIFICATIONS.  This Agreement constitutes the entire 
agreement between the parties respecting the subject matter hereof, and 
supersedes all prior negotiations, undertakings, agreements and arrangements 
with respect thereto, whether written or oral.  Except as otherwise 
explicitly provided herein, this Agreement may not be amended or modified 
except by written agreement signed by the Executive and the Employer.

(c) ENFORCEMENT AND GOVERNING LAW.  The provisions of this Agreement shall be 
regarded as divisible and separate; if any of said provisions should be 
declared invalid or unenforceable by a court of competent jurisdiction, the 
validity and enforceability of the remaining provisions shall not be affected 
thereby.  This Agreement shall be construed and the legal relations of the 
parties hereto shall be determined in accordance with the laws of the State 
of Maryland as it constitutes the situs of the corporation and the employment 
hereunder, without reference to the law regarding conflicts of law.

(d) ARBITRATION.  Except as provided in paragraph (b) of Section 5, any dispute
or controversy arising under or in connection with this Agreement or the 
Executive's employment by the Employer shall be settled exclusively by 
arbitration, conducted by a single arbitrator sitting in Baltimore, MD in 
accordance with the rules of the American Arbitration Association (the "AAA") 
then in effect.  The arbitrator shall be 

                                      8


selected by the parties from a list of eleven (11) arbitrators provided by 
the AAA, provided that no arbitrator shall be related to or affiliated with 
either of the parties.  No later than ten (10) days after the list of 
proposed arbitrators is received by the parties, the parties, or their 
respective representatives, shall meet at a mutually convenient location in 
Baltimore, Maryland, or telephonically.  At that meeting, the party who 
sought arbitration shall eliminate one (1) proposed arbitrator and then the 
other party shall eliminate one (1) proposed arbitrator.  The parties shall 
continue to alternatively eliminate names from the list of proposed 
arbitrators in this manner until each party has eliminated five (5) proposed 
arbitrators.  The remaining arbitrator shall arbitrate the dispute.  Each 
party shall submit, in writing, the specific requested action or decision it 
wishes to take, or make, with respect to the matter in dispute, and the

the Employer shall be entitled to make requisite and appropriate public 
disclosure of the terms of this Agreement, without the Executive's consent or 
approval, as required under applicable statutes, and the rules and 
regulations of the Securities and Exchange Commission and the Stock Exchange 
on which the shares of Employer may from time to time be listed.

(f) WAIVER.  No waiver by either party at any time of any breach by the other 
party of, or compliance with, any condition or provision of this Agreement to 
be performed by the other party, shall be deemed a waiver of any similar or 
dissimilar provisions or conditions at the same time or any prior or 
subsequent time.

prepaid. Notices to the Employer shall be addressed to the principal 
headquarters of the Employer, Attention:  Chairman.  Notices to the Executive 
shall be sent to the address set forth below the Executive's signature on
