         4.       Option to Acquire Bonus Shares.
                  -------------------------------

                  4.1 The Company hereby agrees to grant to Executive as a bonus

an option to acquire three hundred (300,000) thousand (the "Bonus Shares") fully

paid and  non-assessable  shares of common stock, par value $0.01 per share (the

"Common Stock") of the Company. The purchase price for each Bonus Share shall be

the average of the closing price of the Company's Common Stock during the fiscal

quarter ended  December 31, 1999.  One hundred  (100,000)  thousand of the Bonus

Shares may be acquired by Executive on or after March 15, 2000,  and one hundred

(100,000)  thousand of the Bonus Shares may be acquired by Executive on or after

each of October 1, 2001,  and October 1, 2002.  If  Executive is not employed by

the  Company at any of the three  vesting  dates,  he shall not be  entitled  to

acquire the Bonus Shares  attributable  to that date.  The Company  shall at all

times reserve for issuance  and/or  delivery such number of shares of its Common

Stock as shall  be  required  for  issuance  or  delivery  as Bonus  Shares.  No

fractional  shares or scrip  representing  fractional  shares shall be issued as

Bonus  Shares.  Bonus  Shares  will not be  registered  under  federal  or state

securities laws, and will have the status of restricted securities. Bonus Shares

may not be sold or offered  for sale in the  absence of  effective  registration

under such securities laws, or an opinion of counsel satisfactory to the Company

that such  registration is not required.  The Company will not include any Bonus

Shares  in  any  registration   statement  unless  there  shall  be  a  specific

affirmative agreement to do so by an investment banking firm which has agreed to

serve as  underwriter  of a public cash  offering of the  Company's  securities.

Bonus  Shares may be sold by the  Executive  in  transactions  permitted  by the

provisions of Rule 144 of the Securities Act of 1933,  but  notwithstanding  the

provisions  of  Rule  144,  Executive  agrees  that he will  not  undertake  any

disposition of the Bonus Shares in the twelve month period  beginning when sales

under  Rule 144 are  permissible  without  the  approval  of a  majority  of the

disinterested  members of the Board of  Directors  of the  Company.  In case the


                                       -4-


<PAGE>




Company shall at any time subdivide or combine the outstanding  shares of Common

Stock,  the number of Bonus Shares the Executive shall have the right to acquire

shall be proportionately  increased in the case of such subdivision or decreased

in the  case  of  such  combination  (on  the  date  that  such  subdivision  or

combination  shall become  effective).  Bonus  Shares shall bear an  appropriate

restrictive legend, referring to the provisions hereof.

         5. Incentive Compensation.  As incentive compensation to Executive, the

Company hereby grants to Executive the right to acquire from the Company,  on an

original  issue basis,  an aggregate of seven hundred  (700,000)  thousand fully

paid and non-assessable  shares of Common Stock (the "Incentive  Shares") at the

the  several  corporate   accomplishments   (the  "Milestones")   listed  below.

Executive's  right as set forth  herein  shall be  available  at any time on and

employed by the Company,  but not later than 5:00 P.M. (New York time)  December

number of shares which Executive is acquiring  determined in accordance with the

provisions hereof.

         receive such dividend or other  distribution)  or decreased in the case

         of such  subdivision or increased in the case of such  combination  (on

         Paragraph (F) to the contrary notwithstanding, the Company shall not be

         required to give effect to any  adjustment in the Purchase Price unless

         number of shares of Common Stock initially  issuable upon achieving any

         Milestone  by the  Purchase  Price in  effect  on the date  hereof  and

         dividing the product so obtained by the new Purchase Price.

                  of  Common  Stock)  or in case of any  sale or  conveyance  to

                  another  corporation  of the  property  of the  Company  as an

                  entirety or  substantially  as an entirety,  the Company shall

                  cause  effective  provision  to be made so that the  Executive

                  shall  have  the  right  thereafter  as he  has  hereunder  to

                  purchase  the kind and  amount  of  shares  of stock and other

                  sale or conveyance. The foregoing provisions of this Paragraph

                  (G) shall  similarly  apply to  successive  reclassifications,

                  capital  reorganizations and changes of shares of Common Stock

                  sale or conveyance, additional shares of Common Stock shall be

                  of Common  Stock  covered by the  provisions  hereof  with the

                  amount of the  consideration  received  upon the issue thereof

                  being  determined  by the Board of  Directors  of the Company,

                  such determination to be final and binding on the Executive.

and be covered by each  pension,  life  insurance,  accident  insurance,  health

insurance,  hospitalization  and any other employee benefit plan of Company,  as

the case may be, made available  generally from and after the date hereof to its

respective  senior  executives,  on the same basis as shall be available to such

other executives without restriction or limitation by reason of this Agreement.

                  8.5 Nothing herein contained shall prevent the Company from at

any time  increasing the  compensation  herein provided to be paid to Executive,

either  permanently  or for a limited  period,  or from paying bonuses and other

additional compensation to Executive,  whether or not based upon the earnings of

the business of Company,  or from  increasing or expanding any employee  benefit

program  applicable  to the  Executive,  in the event the  Company,  in its sole

discretion,  shall  deem  it  advisable  so to  do in  order  to  recognize  and

compensate fairly Executive for the value of his services.

         9.       Death or Disability.
                  --------------------

                  9.1 If  Executive  shall  die  during  the term  hereof,  this

Agreement  shall   immediately   terminate,   except  that   Executive's   legal

representatives or designated beneficiaries shall be entitled to receive (i) the

Base Salary due to Executive  hereunder  to the last day of the month  following

the month in which his death occurs,  payable in  accordance  with the Company's

regular payroll practices,  (ii) all other benefits payable upon death under any

employee  benefit  program or other  insurance  covering the Executive as of the

date of death;  and (iii) a pro-rated  portion of the Bonus Shares payable under

Section 4.

                  9.2 In  the  event  of the  Disability  of the  Executive,  as

hereinafter  defined,  the  Executive  shall be  entitled to continue to receive

payment of his Base Salary (prorated as may be necessary) in accordance with the

terms of Section 3 hereof through the last day of the third month  following the

month in which  Executive's  employment  hereunder is  terminated as a result of

such  Disability.  At any time  after  the date of the  Notice  (as  hereinafter

defined) and during the continuance of the Executive's  Disability,  the Company

may at any time thereafter terminate Executive's employment hereunder by written

notice to the  Executive.  The term  "Disability"  shall mean physical or mental

illness or injury which  prevents the Executive  from  performing  his customary

duties  for the  Company  for a period  of  sixty  (60)  consecutive  days or an

aggregate period of one hundred twenty (120) days out of any consecutive  twelve

(12) months.  The date of commencement of Disability shall be the date set forth

in the notice  (the  "Notice")  given by Company  to the  Executive  at any time

following a  determination  of Disability,  which date shall not be earlier than

the date the  Notice is given by  Company.  A  determination  of  Disability  by

Company shall be solely for the purposes of this Section 9.2 and shall in no way

affect the  Executive's  status under any other  benefit plan  applicable to the

Executive.

                  9.3 Upon the  occurrence  of a  Disability,   and  unless  the

Executive's  employment  shall have been  terminated as provided in Section 9.2,

the Executive shall, during such time as he is continuing to receive Base Salary

payments  as set forth in  Section  9.2,  perform  such  services  for  Company,

consistent with his duties under Section 1 hereof,  as he is reasonably  capable

of  performing  in light  of the  condition  giving  rise to a  Disability.  All

payments due under  Section 9.2 shall be payable in  accordance  with  Company's

regular  payroll  practices.  Any  amount  paid to  Executive  pursuant  to this


                                      -13-


<PAGE>



Agreement by reason of his Disability,  shall be reduced by the aggregate amount

of all monthly  disability  payments  which the Executive is entitled to receive

under all workers compensation plans,  disability plans and accident,  health or

other  insurance plans or programs  maintained for the Executive by Company,  by

any company controlling, controlled by or under common control with, Company.

                  9.4 In the event the Executive's  employment is terminated due

to Disability,  the Executive shall be entitled,  in addition to the Base Salary

payments  described in Section 9.2, to the Bonus  Shares  payable in  accordance

with Section 4 for the fiscal year in which such Disability occurs, pro-rated by

multiplying the Bonus Shares otherwise issuable by a fraction,  the numerator of

which is the number of days the Executive  was employed  during such fiscal year

and the denominator of which is 365.

         10.      Termination for Cause.
                  ----------------------

                  10.1     The  employment of the Executive may be terminated by

the Company for Cause.  For this purpose, "Cause" shall mean:

                     (i)   an  act   constituting  a  felony  and  resulting  or

                           intended to result,  directly or  indirectly,  in his

                           gain or  personal  enrichment  at the  expense of the

                           Company and its shareholders;

                     (ii)  dishonest acts against the Company;

                     (iii) illegal  drug use;

                     (iv)  grossly  or  willfully  neglecting  to carry  out his

                           duties under this

                           Agreement resulting in material harm to the Company.

         The  Executive's  employment  shall not be  terminated  for Cause under

         clauses (ii) or (iv) unless

         (a) the  Executive has received at least 15 days notice of a meeting of

         the Board of  Directors at which  meeting the Board shall  consider the


                                      -14-


<PAGE>



         existence of Cause,  shall provide the Executive with an opportunity to

         be heard  before the  Board,  and,  following  such  consideration  and

         hearing, the Board has determined,  based upon credible evidence,  that

         grounds for Cause exist; and (b) the misconduct or breaches on which an

         assertion of Cause is based are not cured within 30 days  thereafter if

         such misconduct or breaches are capable of being cured.

                  10.2 In the event of a  termination  for Cause,  the Executive

shall (a) be  entitled  to any  unpaid  Base  Salary pro rated up to the date of

termination,  and (b)  shall  have  no  further  rights  under  this  Agreement.

Furthermore,  the  Executive  shall be and remain  subject to all  provisions of

Section 13 below for the period indicated therein,  but shall not receive any of

the compensation set forth therein.

         11.     Termination Upon Change of Control or by Company Without Cause.
                 ---------------------------------------------------------------

                 11.1 A  "Change in Control" shall occur: (A) if any Person,  or

combination of Persons (as hereinafter  defined), or any affiliate of any of the

above,  is  or  becomes  the  "beneficial  owner"  (as  defined  in  Rule  13d-3

promulgated  under the Securities  Exchange Act of 1934) directly or indirectly,

of securities of the Company  representing twenty- five percent (25%) or more of

the total number of outstanding shares of common stock of the Company; or (B) if

individuals  who,  at the date of this  Agreement,  constitute  the  Board  (the

"Incumbent  Directors") cease, for any reason, to constitute at least a majority

thereof, provided that any new director whose election was approved by a vote of

at least  75% of the  Incumbent  Directors  shall  be  treated  as an  Incumbent

Director. For purposes hereof, "person" shall mean any individual,  partnership,

joint  venture,  association,  trust,  or other  entity,  including a "group" as

referred to in section 13(d)(3) of the Securities Exchange Act of 1934.

                                      -15-


<PAGE>



                  11.2 If  there  occurs  a  Change  in  Control,  and if  there

subsequently  occurs a material adverse change,  without the Executive's written

consent,  in the  Executive's  working  conditions or status,  including but not

limited  to a  significant  change  in the  nature  or scope of the  Executive's

authority,  powers,  duties or responsibilities,  or a reduction in the level of

support  services or staff,  then,  whether or not such change  would  otherwise

constitute  a breach of this  Agreement by the Company,  this  Agreement  may be

terminated by notice given by the  Executive,  specifying  the Change of Control

and significant adverse change or changes.

                  11.3 Upon the termination of this Agreement in accordance with

Section 11.2 above, the Executive will be entitled, without any duty to mitigate

damages, to:

                       (a) All unpaid  Base Salary  pro-rated  up to the date of

                           termination; and

                       (b) The full number of unissued Bonus Shares  pursuant to

                           Section  4;

                       (c) A  severance  payment  equal to 2.99  times  the Base

                           Salary in effect for the prior fiscal year; and

                       (d) All benefits  available under the Company's  employee

                           benefit programs,  to the extent applicable to senior

                           executives  voluntarily  and amicably  retiring  from

                           employment with the Company.

                  11.4  In  the  event  that  the  Company  shall   actually  or

constructively  terminate this Agreement  during the Initial Term or any Renewal

Term  without  cause (and with or without a Change of  Control),  the  Executive

shall be entitled to the same payments,  compensation  and rights as provided in

the case of a termination by the Executive under Section 11.3.

                                      -16-


<PAGE>



                  11.5 The payments and any other  compensation  and benefits to

which the Executive is entitled under this Section 11 shall be made available to

the  Executive no later than thirty (30) days after the date of any  termination

referred to in Section 11.2, 11.3 or 11.4.

                  11.6 In the event that Executive receives the payments and any

other compensation and benefits referred to in this Section 11, he will be bound

by the  restrictive  provisions of Section 13 for the period  therein  provided,

subject to the right to receive the compensation therein set forth.

         12.      Termination by Executive.
                  -------------------------

                  12.1 If the Executive  shall  terminate his  employment  under

this Agreement during the Initial Term without either (i) a Change of Control or

(ii)  the  express  written  consent  of the  Company,  then,  for  purposes  of

establishing the rights of the Executive upon such termination, such termination

shall be deemed the  equivalent of a  termination  for Cause under Section 12.1,

and the Executive  shall have only those rights with regard to  compensation  as

are set forth in Section  12.2,  and the  restrictive  provisions  of Section 13

below  shall  fully  apply  (but the  Executive  shall not have any right to the

compensation set forth therein).

                  12.2 If the Executive  shall  terminate his  employment  under

this Agreement during any Renewal Term without either (i) a Change of Control or

(ii)  the  express  written  consent  of the  Company,  then,  for  purposes  of

establishing  the rights of the Executive upon such  termination,  the Executive

shall be entitled to receive:

                       (a) All unpaid  Base Salary  pro-rated  up to the date of

                           termination; and

                       (b) the full and  absolute  ownership of all Bonus Shares

                           previously   delivered   to  him,   subject   to  the

                           provisions  of the  securities  laws  of  the  United

                           States,  but without  the  specific  limitations  set

                           forth in Section 4 hereof.

<PAGE>



                  12.3 In the case of a  termination  pursuant to Section  12.2,

the restrictions set forth in Section 13 shall apply to Executive for the period

therein  stated,  and the  Executive  shall receive the  compensation  set forth

therein.

         13.      Restrictive Covenants; Compensation.
                  ------------------------------------

                  13.1  During  such time as this  Agreement  shall be in effect

and,  except as otherwise  explicitly  stated herein,  for a period of three (3)

years  following the  termination  of  Executive's  employment,  and without the

Company's  prior written consent (which may be withheld for any reason or for no

reason in Company's sole discretion), Executive shall not do anything in any way

inconsistent  with his duties to, or adverse to the  interests  of, the Company,

nor shall Executive,  directly or indirectly,  himself or by or through a family

member or otherwise,  alone or as a member of a partnership or joint venture, or

as a principal,  officer, director,  consultant,  employee or stockholder of any

other entity,  compete with Company or be engaged in or connected with any other

business competitive with that of Company or any of its affiliates,  except that

Executive may own as a passive investment not more than five percent (5%) of the

securities of any publicly held  corporation  that may engage in such a business

competitive with that of Company or any of its Affiliates.

                  13.2 In view of the fact that  Executive  will be brought into

close contact with many  confidential  affairs of Company and its Affiliates not

readily  available  to the  public,  Executive  agrees  during  the Term of this

Agreement and thereafter:

                           (a) to  keep  secret  and  retain  in  the  strictest

                  confidence all non-public  information  about (i) research and

                  development,  test  results,  suppliers,  venture or strategic

                  partners, licenses and patents or patent applications, planned


                                      -18-


<PAGE>



                  or existing products,  knowhow,  financial condition and other

                  financial affairs (such as costs,  pricing,  profits and plans

                  for future  development,  methods of operation  and  marketing

                  concepts) of Company and its  Affiliates;  (ii) the employment

                  policies  and plans of the  Company  and its  Affiliates;  and

                  (iii)  any  other  proprietary  information  relating  to  the

                  Company  and its  Affiliates,  their  operations,  businesses,

                  financial condition and financial affairs  (collectively,  the

                  "Confidential  Information")  and, for such time as Company or

                  any  of its  Affiliates  is  operating,  Executive  shall  not

                  disclose the  Confidential  Information  to anyone not then an

                  officer,  director  or  authorized  employee of Company or its

                  Affiliates, either during or after the term of this Agreement,

                  except in the course of  performing  his duties  hereunder  or

                  with Company's express written consent or except to the extent

                  that such  confidential  information can be shown to have been

                  in the public domain through no fault of Executive; and

                           (b) to  deliver  to  Company  within  ten days  after

                  termination  of his  services,  or at any time  Company may so

                  request,  all  memoranda,  notes,  records,  reports and other

                  documents  relating to Company or its Affiliates,  businesses,

                  financial  affairs or operations  and all property  associated

                  therewith,  which  he may  then  possess  or  have  under  his

                  control.

                  13.3  Executive  shall not at any time  during the  three-year

period  following the  termination of his employment for any reason  whatsoever,

including  termination resulting from the natural expiration of the term of this

Agreement,  (i) employ any  individual who was employed by Company or any of its

Affiliates at any time during  the such period or during the 12  calendar months

                                      -19-


<PAGE>



immediately preceding such termination,  or (ii) in any way cause,  influence or

participate  in the  employment  of any such  individual  by anyone  else in any

business that is competitive with any of the businesses engaged in by Company or

any of its Affiliates.

                  13.4  Executive  shall not at any time  during the three -year

period following the termination of his employment,  for any reason  whatsoever,

including  termination resulting from the natural expiration of the term of this

Agreement,  directly or  indirectly,  either (i) persuade or attempt to persuade

any customer or client of the Company or of any of its Affiliates to cease doing

business with Company or with any Affiliate, or to reduce the amount of business

it does with Company or with any of its Affiliates,  or (ii) solicit for himself

or any person other than Company or any of its  Affiliates,  the business of any

individual  or business  which was a customer or client of Company or any of its

Affiliates at any time during the eighteen  month period  immediately  preceding

such termination.

                  13.5 Executive acknowledges that the execution and delivery by

him of the promises set forth in this Section 13 is an essential  inducement  to

Company to enter into this  Agreement,  and that Company  would not have entered

into this Agreement but for such promises.  Executive further  acknowledges that

his services are unique and that any breach or threatened breach by Executive of

any of the foregoing  provisions of this Section 13 cannot be remedied solely by

damages.  In the event of a breach or a threatened breach by Executive of any of

the  provisions  of this  Section 13,  Company  shall be entitled to  injunctive

relief restraining Executive and any business,  firm,  partnership,  individual,

corporation or other entity  participating  in such breach or attempted  breach.

Nothing herein, however, shall be construed as prohibiting Company from pursuing


                                      -20-


<PAGE>



any other  remedies  available at law or in equity for such breach or threatened

breach,  including the recovery of damages and the immediate  termination of the

employment of Executive hereunder.

                  13.6 If any of the  provisions  of, or promises  contained in,

this Section 13 are hereafter  construed to be invalid or  unenforceable  in any

jurisdiction,  the same shall not affect the remainder of the  provisions or the

enforceability  thereof  in any other  jurisdiction,  which  shall be given full

effect,  without regard to the invalid portions or the  unenforceability in such

other jurisdiction.  If any provisions  contained in this Section 13 are held to

be unenforceable  in any jurisdiction  because of the duration or scope thereof,

the parties hereto agree that the court making such determination shall have the

power to reduce the  duration  and/or scope (if such  provision,  in its reduced

form, shall be enforceable);  provided,  however, that the determination of such

court shall not affect the enforceability,  duration or scope of this Section 13

in any other jurisdiction.

                  13.7 As separate and additional compensation to be paid to the

Executive in  consideration  of the observance  and  performance of the promises

contained  in this  Section 13, the Company  agrees  that,  during the period of

restrictions  set forth in this Section 13, the Executive will be entitled to be

paid an amount  equal to 100% of the Base  Salary  computed  at the annual  rate

prevailing  immediately  prior to the termination of his employment (such amount

to be paid in the same  manner  as the  Company's  regular  payroll  practices),

except that, (i) in the case of termination  of the  Executive's  employment for

Cause,  or in case the Executive  shall  terminate this Agreement  under Section

12.1 during the Initial Term, the Executive will receive no such compensation

         14.      Relationship of Parties.

and may, on a date established by the tiebreaker within fifteen calendar days of

the day the tiebreaker is chosen,  make an oral  presentation  not to exceed two

tiebreaker  may be  enforced  on  application  of  either  party by the order or

judgment  of any  Federal or state  court in the State of  Maryland as the party

making such application shall elect, having jurisdiction over the subject matter

thereof. Each of the parties hereto hereby submits itself to the jurisdiction of

any such court and agree that  service of process on it in any  action,  suit or

proceeding  to  enforce  any such  award may be  effected  by the means by which

notices are to be given to it under this Agreement.
