         3. COMPENSATION.

            (a)  Base Salary.  InforMax  shall pay, and Employee  shall  accept,

commensurate with performance at the  sole  discretion of  the CEO and the Board
of Directors of InforMax.

            (b)  Stock Options.  Employee  shall be granted  options to purchase
shares of  non-voting  common  stock as  described  in  separate  stock   option
agreements.  All  options  shall be  governed  by  InforMax's  Equity  Incentive
Compensation Plan.

            (c)  Benefit Plans. Employee  shall  be  entitled  to participate in
such benefit plan(s) of InforMax now in existence or which may hereafter  during
the term of this Agreement become  effective for senior  executives of InforMax.
Nothing in this Section 3(c) shall be deemed to prevent  InforMax  from altering
or  abolishing  any of such  plans or  benefits  provided  that all such  senior
executives are treated equally.

            (d)  Vacation. During the term of this Agreement,  Employee shall be
entitled to three (3) weeks paid  vacation in  accordance  with the  established
policy of  InforMax.  Employee  also shall be entitled to all paid  holidays and

            (e)  Expenses. InforMax  shall  promptly  pay  or reimburse Employee
upon  submission  of  vouchers  or  receipts  for all  reasonable  out-of-pocket
expenses for entertainment,  travel,  meals, hotel  accommodations and the like,

            (f)  Withholding.  Employee acknowledges  that InforMax may withhold
from amounts  payable to Employee  under this  Agreement with respect to certain
income,  unemployment and social security taxes required to be withheld from the
wages of employees  under  applicable  Federal,  State,  and local law. No other
taxes, fees, impositions,  duties or other charges of any kind shall be deducted
or withheld from amounts payable hereunder,  unless otherwise required by law or
agreed to by Employee.

         4. TERMINATION OF EMPLOYMENT.  Notwithstanding any provisions herein to
the contrary, Employee's employment with InforMax may be terminated prior to the
completion of the term described in Section 2 of this Agreement,  subject to the
following terms and conditions:

            (a)  Termination  for  Cause.   InforMax  may  terminate  Employee's
employment at any time for Cause.  For the purpose of this  Agreement,  the term
"Cause" shall mean  Employee's (1) willful  misconduct; (2) gross  negligence or
incompetence  in the performance of his duties for more than five (5) days after
receiving  written  notice from InforMax on the grounds of purported  failure to
perform and corresponding  failure by Employee to cure such breach within thirty
(30) days of written  notice;  (3)  willful  violation  of any law  (other  than
traffic

                                       2

<PAGE>

violations or similar offenses) or final cease-and-desist order  in  performance
of his duties; or (4) material breach of any provision of this Agreement.

            (b)  Termination  Without  Cause upon a Change of Control.  InforMax
shall pay Employee a sum equal to his annual base salary plus earned commissions
and  bonuses  for the  previous  twelve  (12) months at the time of a "Change in
Control" upon termination by InforMax or its successor or assignee of Employee's
employment  without  Cause  within  365 days of a "Change in  Control".  For the
purposes of this Section a "Change of Control" of the Company shall be deemed to
have  occurred  if (i) any  person or entity  other  than a person  currently  a
beneficial owner of the Company's securities becomes, after the date hereof, the
beneficial  owner of securities of the Company  representing  50% or more of the
combined voting power of the Company's then outstanding securities,  or (ii) the
Company sells all or substantially all or substantially all of the assets of the
Company.

            (c)  Termination  Without Cause other than upon a Change of Control.
InforMax  shall pay Employee a lump-sum cash payment in an amount equal to fifty
percent  (50%) of his  annual  salary  plus  fifty  percent  (50%) of his earned
commissions and bonuses for the previous twelve (12) months upon  termination by
InforMax  of  Employee's  employment  without  Cause  other than as  provided in
Section 4(b) above.  The severance  payment shall be paid to Employee in cash as
promptly as  practicable,  but in no event later than thirty (30) days following
the  termination  of his  employment.  Employee's  Options will continue to vest
until the end of the sixth month after termination without Cause.

            (d)  Termination by Employee for Breach by InforMax or its Successor
or Assignee.  In the event that InforMax or its  successor or assignee  breaches
this  Agreement  in any  material  respect  and fails to cure the breach  within
thirty (30) days of written notice,  Employee may terminate his  employment.  In
the event of such  termination,  InforMax or its successor or assignee shall pay
Employee a lump-sum  cash payment in an amount equal to fifty  percent  (50%) of
his annual salary plus fifty percent (50%) of his earned commissions and bonuses
for the previous  twelve (12) months.  The  severance  payment  shall be paid to
Employee in cash as promptly as  practicable,  but in no event later than thirty
(30) days following such termination.

            (e) Voluntary Termination by Employee without Cause. Any termination
of  Employee's  employment  by  resignation,  retirement  or any other action of
Employee  for any reason other than as set forth in Section 4(d) shall be deemed
to be a "Voluntary  Termination."  Employee shall give InforMax thirty (30) days
notice of a Voluntary Termination.

            (f) Payment Upon  Termination  For Cause or  Voluntary  Termination.
InforMax's  obligation  to pay  Employee any and all  compensation  and benefits
shall cease in the event of a Termination for Cause or a Voluntary  Termination,
and InforMax shall not be liable for any further payments to Employee  hereunder
except for accrued salary, accrued vacation

                                       3

<PAGE>

days,  reimbursement of appropriate expense vouchers, applicable indemnification
obligations and other benefit continuation obligations imposed by law.

         5.  DEVOTION  OF TIME.  Except for  vacations  as  provided  herein and
absences  due to temporary  illness or family  emergencies,  Employee  agrees to
devote his business  time,  best efforts and  undivided  attention  and energies
during  the term of this  Agreement  to the  performance  of his  duties  and to
advance InforMax's interests. During the term of this Agreement,  Employee shall
not,  without  the prior  written  approval  of the Board of  Directors,  or its
designee,  be engaged in any other business  activity  which,  in the reasonable
judgment  of the  Board of  Directors,  conflicts  with the duties of  Employee,
whether or not such  business  activity  is pursued for gain,  profit,  or other
pecuniary  advantage;  but this restriction shall not be construed as preventing
Employee  from  investing  his assets in such form or manner as will not require
the  performance of services of Employee in the operations of the affairs of the
enterprises or companies in which said investments are made. Notwithstanding the
foregoing, services  which are neither substantial nor significant, individually
or in the aggregate,  shall be permitted with respect to investments of Employee
provided  that  they  shall not have an  adverse  effect  on  Employee's  duties
hereunder.

         6.   NON-COMPETITION.   Employee  agrees  that  during  the  period  of
Employee's  employment  by  InforMax  and for a  period  of one (1)  year  after
termination of this Agreement in accordance with sections 4(a), 4(e) or 4(f):

               (i)   Employee will not solicit business from or perform work for
         any of  InforMax's  past  or  present  clients,  or  any of  InforMax's
         prospective clients to whom InforMax has made a written proposal within
         six (6) months prior to any  termination of Employee's  employment with
         InforMax,  either  directly  or  indirectly,  for the benefit of anyone
         other  than  InforMax,  or  participate  or  assist  in any  way in the
         solicitation  of  business  from or  performance  of work  for any such
         clients, as an independent contractor or consultant to any other entity
         unless the business being  solicited or the work being performed is not
         the Same Business as that in which InforMax is engaged. As used in this
         Agreement,  the term "Same  Business"  means any  business in which the
         InforMax  is  currently  engaged  at the  time  of  termination  or any
         business in which the Board of Directors has approved,  in its minutes,
         plans to enter.

               (ii)  Employee will not divert, solicit,  or pirate on Employee's
         behalf, or on the behalf of any other employer,  person, or entity, any
         employee of InforMax,  or directly or  indirectly  induce or attempt to
         influence any such employee to leave InforMax's employment.

               (iii) Employee will not,  directly or  indirectly,  on Employee's
         behalf or in the service or on behalf of others,  render or be retained
         to render services whether as an officer, partner, trustee, consultant,
         or employee, for any business engaged in the Same

                                       4

<PAGE>

         Business  as  InforMax  including  but not  limited to any  customer of
         InforMax  for whom  Employee has provided  services  during  Employee's
         employment  with InforMax,  unless the same is provided  solely to that
         portion or unit of any such  business  that is not  engaged in the Same
         Business.

               (iv) The business of InforMax is  international  in scope and the
         restrictions of this paragraph shall accordingly apply worldwide.

         7. NONDISCLOSURE OF PROPRIETARY INFORMATION.  Both during and after the
term  of  this   Agreement,   Employee   agrees  to  preserve  and  protect  the
confidentiality  of Proprietary  Information  as defined in Section 8 below.  In
addition,  Employee will not (i) disclose or disseminate Proprietary Information
to any third party, including  employees of InforMax  without a need to know, or
(ii) use  Proprietary  Information for his own benefit or for the benefit of any
third party. If Employee receives information with uncertain confidentiality, he
agrees to treat the information as Proprietary  Information until management has
verified to him that such information is neither confidential nor proprietary.

         8. DEFINITION OF PROPRIETARY  INFORMATION.  Proprietary  Information is
defined  as  information  regarding  InforMax's  current  and  planned  business
activities,  including (i)  information  which  relates to InforMax's  actual or
anticipated  products,  software,  research inventions,  processes,  techniques,
designs or other  technical  data; (ii)  information  regarding  administrative,
financial or marketing  activities of InforMax;  (iii) information received from
InforMax  clients and other third  parties;  and (iv) any materials or documents
containing  any of the  above  information.  Proprietary  Information  does  not
include  information which is or becomes publicly  available without a breach of
this  Agreement  by Employee or any  information  that  Employee is obligated to
disclose to third parties by law.

         9.  RETURN  OF  PROPRIETARY   INFORMATION.   Upon  termination  of  his
employment  with InforMax,  Employee agrees to deliver to InforMax all documents
and other tangibles  including  diskettes and other  electronic or other storage
media containing Proprietary Information.

         10. TRADE SECRETS.  Employee understands and agrees that the covenants,
restrictions and prohibitions against disclosure of Proprietary  Information set
forth in this  Agreement  are in addition  to, and not in lieu of, any rights or
remedies  which  InforMax  may  have  available  pursuant  to  the  laws  of any
jurisdiction  or at  common  law to  prevent  disclosure  of  trade  secrets  or
proprietary  information,  and the  enforcement  by  InforMax  of its rights and
remedies  pursuant to this  Agreement  shall not be construed as a waiver of any
other rights or available  remedies which it may possess in law or equity absent
this Agreement.

         11.  OWNERSHIP  OF WORKS.  During  the time  Employee  is  employed  by
InforMax,  InforMax  shall  own all  rights,  including  all trade  secrets  and
copyrights, in and to the following works created by Employee whether created on
InforMax's premises or at some other location:

                                       5

<PAGE>

(i) works which relate to or are derived from the actual or anticipated business
of  InforMax  and (ii) works  which  result  from or are  derived  from any task
assigned to Employee or work  performed by Employee for InforMax  (collectively,
the  "Works").  InforMax  shall own such Works even if  created  outside  normal
working hours and  regardless of whether  Employee's own equipment or InforMax's
equipment was used to create the Works.  Such Works shall include  program codes
and  documentation.  To the extent  that any such Works do not  qualify as works
made for hire under U.S.  copyright  law,  this  Agreement  will  constitute  an
irrevocable  assignment  by Employee to  InforMax of the  ownership  of, and all
rights of  copyright  in, such Works.  Employee  agrees to give  InforMax or its
designees all  assistance  reasonably  required to perfect such rights  provided
that following termination of this Agreement,  InforMax shall reimburse Employee
for his reasonable time and expense in assisting with such matters.

         12. INVENTIONS.  If Employee individually or jointly makes or conceives
of any invention,  technique,  process, or other know-how, whether patentable or
not, in the course of  performing  services  for Employee  for  InforMax,  which
relates in any manner to the  actual or  anticipated  business  of  InforMax  or
results  from any task  assigned to Employee or work  performed  by Employee for
InforMax (collectively,  "Inventions"),  Employee will and hereby does assign to
InforMax his entire right, title and interest in such Inventions.  Employee will
disclose any such  Inventions to an officer of InforMax and will,  upon request,
promptly sign a specific  assignment of title to InforMax,  and do anything else
reasonably  necessary to enable InforMax to secure patents,  trade secret or any
other  proprietary  rights in the United States or foreign  countries,  provided
that following termination of this Agreement,  InforMax shall reimburse Employee
for his  reasonable  time and  expense  in  assisting  with  such  matters.  Any
Inventions  Employee has made or  conceived  before the  effective  date of this
Agreement  are listed and described on Schedule A attached  hereto.  These items
are excluded from this Agreement.

         13.  INDEMNIFICATION.   InforMax  shall  indemnify  and  hold  harmless
Employee  in his  capacity  as an  officer as  provided  in the  certificate  of
incorporation  and  by-laws  of  InforMax,  as amended  from time to time.  This
provision shall in no manner limit  InforMax's right to amend its certificate of
incorporation or by-laws.

         14. ASSIGNABILITY. This Agreement and all rights hereunder are personal
to Employee and shall not be assignable  except in  accordance  with the laws of
descent and  distribution,  and any purported  assignment  in violation  thereof
shall not be valid or binding on InforMax. This Agreement,  however, shall inure
to the benefit  of, and be binding  upon each  successor  of  InforMax,  whether
resulting  from  a  merger  or  consolidation  or to  the  recipient  of  all or
substantially all of the assets of InforMax (and such successor shall thereafter
be deemed the same as InforMax for purposes of this  Agreement).  This Agreement
shall in no way restrict  InforMax's  right to merge,  consolidate,  sell all or
substantially  all of its assets or engage in any business  combination or other
transaction of any nature.

                                       6

         15.  ENTIRE  AGREEMENT.  This  Agreement,  including  any  Schedule  A,
supersedes  and  replaces any and all present,  written or oral,  agreements  of
employment between the parties hereto, and all such agreements are hereby deemed
canceled, revoked, and of no further force or effect.

          16.  ACKNOWLEDGMENT.  The restrictions  contained in Section 6 of this
Agreement are  considered  reasonable  by Employee and  InforMax,  and it is the
desire of both parties that such  restrictions  and the other provisions of this
Agreement be enforced to the fullest extent  permissible  under the laws and the
public policies applied in each  jurisdiction in which  enforcement is sought. A
deletion  resulting from any  adjudication  shall occur only with respect to the
operation  of the  provision  or a portion  thereof  affected in the  particular
jurisdiction  in which such  adjudication  is made, and each court or other body
having jurisdiction with respect to the enforcement of the provisions of Section
6 of this  Agreement are hereby  empowered to modify by  reduction,  rather than
deletion, the time periods or other restrictions referred to therein.

          17.  MODIFICATION.  This Agreement  constitutes the whole agreement of
employment  of  Employee  by  InforMax  and there are no terms  other than those
stated herein.  No variation  hereof shall be deemed valid unless in writing and
signed by the parties  hereto,  and no  discharge  of the terms  hereof shall be
deemed valid unless by full  performance  by the parties hereto and by a writing
signed by the parties  hereto.  No waiver by either  party of any  provision  or
condition  of this  Agreement  by him or it to be  performed  shall be  deemed a
waiver of similar or dissimilar  provisions  and  conditions at the same time or
any prior or subsequent time.

          18. NOTICES. Any notice, statement, report, request or demand required
or permitted  to be given by this  Agreement  shall be in writing,  and shall be
sufficient if addressed and sent by certified mail, return receipt requested, to
the parties at the  addresses set forth above or at such other place that either
party may designate by notice to the other.

          19.  EQUITABLE  RELIEF/PAYMENT  OF FEES. The parties to this Agreement
agree that each of them shall be  entitled,  in addition  to any other  remedies
they  may  have  under  this  Agreement,  at law,  or  otherwise,  to  immediate
injunctive and other  equitable  relief to prevent or curtail any breach of this
Agreement.  Each party  agrees to indemnify  the other party for all  reasonable
costs and attorneys' fees incurred in enforcing this Agreement  should the first
such party  prevail in any  litigation  over a breach of any  provision  of this
Agreement.

          20. GOVERNING LAW. This Agreement shall be governed by the laws of the
State of Maryland  (regardless  of the laws that might  otherwise  govern  under
applicable principles or conflicts of law) as to all matters,  including but not
limited to matters of validity, construction, effect, performance and remedies.

          21. COUNTERPARTS. This Agreement may be executed in counterparts, each
of which shall be deemed an original,  but which together  shall  constitute one
and the same instrument.

          23.  LIMITED  AGREEMENT.  This Agreement is intended by the parties to
govern only those rights and  obligations  described  herein,  and it is not the
parties'  intent to abrogate  any other  rights in favor of Employee or InforMax
provided under Federal or State Law.

          IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date set forth above.
