         This Employment Agreement dated as of December 7, 2001 (this
"Agreement"), is made by and between Back Bay Technologies, Inc., a Delaware
corporation (the "Company"), and Marc P. Maselli (the "Employee").

         WHEREAS, the Company wishes to employ Employee and Employee desires to
be an employee of the Company;

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants and agreements herein contained, the parties hereto agree as follows:

         1. EMPLOYMENT. The Company hereby employs Employee to perform those
duties and services as the Company shall from time to time set forth, and
Employee accepts employment with the Company, upon the terms and conditions
hereinafter set forth. Employee shall serve as President of the Company and
shall report to the Board of Directors of the Company (the "Board"), which shall
have the right to review and change the responsibilities of Employee from time
to time as it may deem necessary or appropriate, PROVIDED, however, that such
responsibilities shall not be inconsistent with the Employee's position as
President.

         2. DUTY TO PERFORM SERVICES. Employee shall devote his full time during
normal business hours to rendering services to the Company hereunder, and shall
exert all reasonable efforts in the rendering of such services. Provided
Employee is in compliance with the immediately preceding sentence, nothing in
this Agreement shall prohibit Employee from (a) serving on the board of
directors of up to two companies not developing or selling a product or
technology in the same business of the Company, provided that he shall not be
required to render any material services with respect to the operations or
affairs of any such company, (b) making and managing passive investments, or (c)
engaging in religious, charitable or other community or non-profit activities.

         Employee agrees that in the rendering of all services to the Company
and in all aspects of employment hereunder, he shall comply in all material
respects with all directives, policies, standards and regulations from time to
time established by the Company, to the extent they are not in conflict with
this Agreement.

         3. TERM OF AGREEMENT. The term of Employee's employment with the
Company shall be three (3) years. The Company may terminate Employee's
employment with the Company at any time with or without Cause (as defined in
Section 17) and Employee may terminate his employment with the Company at any
time with or without Good Reason (as defined in Section 17).

         4.  COMPENSATION.

                  (a) BASE SALARY. During the term of this Agreement, the
Company shall pay Employee a base salary, payable in equal installments in
accordance with the Company's standard schedule for salary payments to its
employees, at an annual rate equal to $200,000

<PAGE>

PROVIDED, however, that Employee may unilaterally reduce his base salary for any
period, the beginning and ending of which shall be specified by Employee
entirely in his own discretion. Employee's base salary shall be reviewed
annually by the Company and may be increased on or after each anniversary of
this Agreement by the Company.

                  (b) BONUS. In December 2001 and on each anniversary
thereafter, the Company may pay Employee an annual year-end bonus in an amount
and in a form (E.G., cash or stock options) to be reasonably determined by the
Board. When determining the amount of Employee's annual bonus, the Board shall
consider the revenue, growth and profitability of the Company during the
preceding twelve months and Employee's achievement of any specific performance
goals that the Board and Employee shall agree upon from time to time. Employee
shall also be eligible to participate in the Company's profit-sharing plan,
along with other senior executives of the Company.

         5.  VACATIONS, HOLIDAYS AND SICK TIME; BENEFITS.

                  (a)   HOLIDAYS AND SICK TIME. Employee shall be entitled to 20
paid vacation days annually, and shall not be required to work but shall be paid
for all major U.S. holidays.

                  (b)   BENEFITS. Employee and, to the extent applicable,
Employee's family, dependents and beneficiaries, shall be entitled to
participate in the Company's 401(k) plan, receive medical, dental, disability
and life insurance coverage through the Company, use of wireless phone and
laptop computer for business purposes and such other benefits as may be provided
by the Company to its other employees generally from time to time (collectively,
the "Benefits").

         6. EXPENSES. The Company shall pay or reimburse Employee for all
reasonable business expenses incurred by Employee in connection with his
employment by the Company in accordance with the Company's policies in effect
from time to time, subject to presentation of appropriate documentation.

         7. CONFIDENTIAL INFORMATION. While employed by the Company and
thereafter, Employee shall not, directly or indirectly, use any Confidential
Information (as defined below) other than pursuant to his employment by and for
the benefit of the Company, or disclose any Confidential Information to anyone
outside of the Company, whether by private communication, public address,
publication or otherwise, or disclose any Confidential Information to anyone
within the Company who has not been authorized to receive such information,
except as directed in writing by an authorized representative of the Company.
The term "Confidential Information" as used throughout this Agreement shall mean
all trade secrets, proprietary information, know-how, data, designs,
specifications, processes, customer lists and other technical or business
information (and any tangible evidence, record or representation thereof),
whether prepared, conceived or developed by an employee of the Company
(including Employee) or received by the Company from an outside source, which is
in the possession of the Company (whether or not the property of the Company),
which in any way relates to the business of the Company, which is maintained in
confidence by the Company, or which might permit the Company or its customers to
obtain a competitive advantage over competitors who do not have access to such
trade secrets, proprietary


                                      -2-

relating to any of the foregoing (in each case whether or not reduced to
tangible form); and

               (b) the name of any employee, consultant, customer or prospective
customer, or any other customer or prospective customer information, any sales
plan, marketing material, plan or survey, business plan or opportunity, product

not apply to information which (i) the Company has voluntarily disclosed to the
public without restriction, (ii) has otherwise lawfully entered the public
domain or (iii) the Employee is required to use or disclose pursuant to an order
of law (provided that employee shall provide notice to the Company of such
action).

         Employee acknowledges that the Company from time to time has in its
possession information which is claimed by customers and potential business
partners to be proprietary and which the Company has agreed to keep
confidential. Employee agrees that all such information shall be Confidential
Information for purposes of this Agreement.

         8. OWNERSHIP AND ASSIGNMENT OF INTELLECTUAL PROPERTY. Employee agrees
that all originals and all copies of all manuscripts, drawings, prints, manuals,
diagrams, letters, notes, notebooks, reports, models, records, files, memoranda,
plans, sketches and all other documents and materials containing, representing,
evidencing, recording, or constituting any Confidential Information (as defined
in Section 7 above), however and whenever produced (whether by Employee or
others) during the course of his employment with the Company, shall be the sole
property of the Company.

         Employee agrees that all Confidential Information and all other
discoveries, inventions, ideas, specifications, designs, concepts, research and
other information, processes, products, methods and improvements, or parts
thereof conceived, developed, or otherwise made by him, alone or jointly with
others and in any way relating to the Company's present or proposed products,
programs or services or to tasks assigned to him during the course of his
employment, whether or not patentable or subject to copyright protection and
whether or not reduced to tangible form or reduced to practice, during the
period of his employment with the Company, whether or not made during his
regular working hours, and whether or not made on the Company's premises, and
whether or not disclosed by him to the Company (hereinafter referred to as
"Intellectual Property") together with all products or services which embody or
emulate any Intellectual Property shall be the sole property of the Company.


                                      -3-
<PAGE>

         Employee agrees to, and hereby does, assign to the Company all his
right, title and interest throughout the world in and to all Intellectual
Property and to anything tangible which evidences, incorporates, constitutes,
represents or records any Intellectual Property. Employee agrees that all
Intellectual Property shall constitute works made for hire under the copyright
laws of the United States and hereby assigns and, to the extent any such
assignment cannot be made at present, Employee hereby agrees to assign to the
Company all copyrights, patents and other proprietary rights Employee may have
in any Intellectual Property, together with the right to file for and/or own
wholly without restriction United States and foreign patents, trademarks, and
copyrights. Employee agrees to waive, and hereby waives, all moral rights or
proprietary rights in or to any Intellectual Property and, to the extent that
such rights may not be waived, agrees not to assert such rights against the
Company or its licensees, successors or assigns.

         Employee hereby certifies that EXHIBIT A sets forth any and all
confidential information and intellectual property that Employee claims as his
own or otherwise intends to exclude from this Agreement because it was developed
by him prior to the date of this Agreement. Employee understands that after
execution of this Agreement he shall have no right to exclude Confidential
Information or Intellectual Property from this Agreement.

         9.  EMPLOYEE'S OBLIGATION TO KEEP RECORDS. Employee shall make and
maintain adequate and current written records of all Intellectual Property,
including notebooks and invention disclosures, which records shall be available
to and remain the property of the Company at all times. Employee shall disclose
all Intellectual Property promptly, fully and in writing to the Company
immediately upon production or development of the same and at any time upon
request.

         10. EMPLOYEE'S OBLIGATION TO COOPERATE. Employee will, at any time
during his employment, or after it terminates, upon request of the Company,
execute all documents and perform all lawful acts which the Company considers
necessary or advisable to secure its rights hereunder and to carry out the
intent of this Agreement. Without limiting the generality of the foregoing,
Employee will assist the Company in any reasonable manner to obtain for its own
benefit patents or copyrights in any and all countries with respect to all
Intellectual Property assigned pursuant to Section 8, and Employee will execute,
when requested, patent and other applications and assignments thereof to the
Company, or persons designated by it, and any other lawful documents deemed
necessary by the Company to carry out the purposes of this Agreement, and
Employee will further assist the Company in every way to enforce any patents and
copyrights obtained, including testifying in any suit or proceeding involving
any of said patents or copyrights or executing any documents deemed necessary by
the Company, all without further consideration than provided for herein. It is
understood that reasonable out-of-pocket expenses of Employee's assistance
incurred at the request of the Company under this Section will be reimbursed by
the Company.

         11. NONCOMPETITION. During the Noncompetition Period (as defined in
Section 17), Employee shall not, directly or indirectly, on his own behalf, or
as owner, manager, stockholder, consultant, director, officer, or employee of
any business entity (except as a holder of not more than one (1%) percent of the
stock of a publicly held company) participate, directly or indirectly, in any
capacity, in any business that derives more than 50% of its revenues from
providing information technology consulting services.


                                      -4-
<PAGE>

         12. NONSOLICITATION. During the Noncompetition Period, Employee shall
not (i) solicit, encourage, initiate discussions with or take any other action
which is intended to induce any other employee of, or full-time consultant to,
the Company to terminate his employment or relationship with the Company in
order to become employed by or otherwise perform services for any other Person
or (ii) solicit, endeavor to entice away from the Company or otherwise interfere
with the relationship of the Company with any Person who is a client or customer
of the Company.

         13. RETURN OF PROPERTY. Upon termination of Employee's employment with
the Company, or at any other time upon request of the Company, Employee shall
return promptly any and all customer or prospective customer lists, other
customer or prospective customer information or related materials, computer
programs, software, electronic data, specifications, drawings, blueprints, data
storage devices, reproductions, sketches, notes, notebooks, memoranda, reports,
records, proposals, business plans, or copies of them, other documents or
materials, tools, equipment, or other property belonging to the Company or its
customers which Employee may then possess or have under his control.

         14.  AUTHORITY.  Employee hereby represents, warrants and agrees that

services required of him hereunder, without any restriction whatsoever (E.G.,
any noncompetition agreements with previous employers).

         15. TERMINATION EVENT. The following events shall each be considered a
"Termination Event" and, upon the occurrence of any of them, shall have the

limitation."

         19. AMENDMENTS AND SUPPLEMENTS. This Agreement may not be altered,

binding on the Company unless approved by the Board.

         20. NO WAIVER. The terms and conditions of this Agreement may be waived
only by a written instrument signed by the party waiving compliance. In the case
of the Company, no waiver shall be effective unless approved by the Board. The
failure of any party hereto to enforce at any time any of the provisions of this
Agreement shall in no way be construed to be a waiver of any such provision, nor
in any way to affect the validity of this Agreement or any part hereof or the
right of such party thereafter to enforce each and every such provision. No
waiver of any breach of or non-compliance with this Agreement shall be held to
be a waiver of any other or subsequent breach or non-compliance. The rights and

at the following addresses (or at such other address for a party as shall be
specified by like notice), and shall be deemed given on the date on which
delivered by hand or otherwise on the date of receipt as confirmed:

         To the Company:

                Back Bay Technologies, Inc.
                368 Hillside Avenue
                Needham, MA  02494
                Attention: President

         To Employee:

                Marc P. Maselli

         23. ENTIRE AGREEMENT, ASSIGNABILITY, ETC. This Agreement constitutes
the entire agreement among the parties with respect to the subject matter hereof
and supersedes all other prior agreements and understandings, both written and
oral, between the parties with respect to such subject matter. This Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and permitted assigns. This Agreement is not intended to
confer upon any person other than the parties hereto any rights or remedies
hereunder, except as otherwise expressly provided herein and shall not be
assignable by operation of law or otherwise.

         24. SURVIVAL; VALIDITY. Except as expressly provided herein, the
provisions of this Agreement shall not survive termination of Employee's
employment by the Company for any reason. In the event that any provision of
this Agreement shall be determined to be unenforceable by reason of its
extension for too great a period of time or over too large a geographic area or
over too great a range of activities, it shall be interpreted to extend only
over the maximum period of time, geographic area or range of activities as to
which it may be enforceable. If, after application of the preceding sentence,
any provision of this Agreement shall be determined to be invalid, illegal or
otherwise unenforceable by a court of competent jurisdiction, the validity,
legality and enforceability of the other provisions of this Agreement shall not
be affected thereby. Except as otherwise provided in this Section 24, any
invalid, illegal or unenforceable provision of this Agreement shall be
severable, and after any such severance, all other provisions hereof shall
remain in full force and effect.

         25. REMEDIES. The parties hereto recognize that money damages alone
would not adequately compensate the parties in the event of breach by the other
party of this Agreement, and the parties therefore agree that, in addition to
all other remedies available to them at law, in equity or otherwise, they shall
be entitled to injunctive relief for the enforcement hereof. All rights and
remedies hereunder are cumulative and are in addition to and not exclusive of
any other rights and remedies available at law, in equity, by agreement or
otherwise.

         26.  COUNTERPARTS.  This Agreement may be executed in one or more
counterparts, all of which together shall constitute one and the same Agreement.
