                                  THE COMPANY
 
     Nextera Enterprises, Inc. provides leading-edge business strategy,
operations improvement, organizational design and information technology ("IT")
consulting services primarily to Fortune 500 and other multinational companies.
The Company provides services in four practice areas, which enables it to offer
a breadth and balance of services that assist clients in achieving enhanced
business performance by anticipating and addressing their complex,
multi-disciplinary consulting needs. By developing dynamic business strategies
and high performance business processes and enhancing organizational
effectiveness, the Company helps clients identify and examine business problems
and implement the strategic, organizational and operational responses needed to
solve such problems and sustain performance improvement.
 
     The professional consulting services industry is driven by changes in the
business environment, such as increased competition, deregulation,
globalization, technological advances and evolving organizational models. In
response to these changes, many organizations are altering traditional
approaches to overall strategy, business processes, organizational design and
the use of IT. Lacking the skilled personnel, technical capabilities and time
necessary to formulate and implement strategies to benefit from these changes,
many organizations are increasingly retaining third-party service professionals
for help and expertise. According to an industry source, the worldwide market
for professional consulting services is estimated to be $46.3 billion in 1997
and is projected to increase to $88.5 billion in 2002. Consulting service
providers employing traditional approaches typically do not offer the broad and
balanced perspective and integrated solutions critical to solving the
multi-disciplinary problems organizations are currently facing. In order to
solve such problems, organizations are demanding that third-party providers have
experience in a breadth of practice areas.
 
     The Company's portfolio of practice areas includes Business Research
Services, Strategic Management Services, Human Capital Services, and Business
Performance Solutions. The Business Research Services practice provides in-depth
and forward-looking analyses of business challenges, frameworks, and innovative
business practices. The Strategic Management Services practice helps
organizations set and pursue their goals and develop the ability of senior
management to proactively refine and manage business strategies, action plans,
and core competencies as these goals are implemented throughout the
organization. The Human Capital Services practice assists clients to implement
organizational and strategic changes established by senior management through
all levels of the organization. The Business Performance Solutions practice
helps organizations solve complex operational issues through major business
transformation programs, redesigned business processes, best practices
adaptation, and the use of emerging technologies such as web-based technologies
and electronic commerce for high impact business process support systems and
knowledge management systems.

     Nextera's flexible delivery model and its ability to leverage its knowledge
base enable it to provide timely and unbiased perspectives on clients'
enterprise-wide management problems and cost-effectively implement
multi-disciplinary solutions. The Company's breadth of expertise enables it to
deliver services initially in any of its four practice areas and offers
opportunities to expand the scope of its engagements to include complementary or
follow-on services in other practice areas. The Company provides its services
across a broad spectrum of industries, including communications, consumer
products and services, entertainment, financial services, health care,
insurance, manufacturing, professional services, retail and technology.
Representative clients include The Chubb Corporation, International Business
Machines Corporation, Levi Strauss & Co., Mead Johnson & Company, National
Broadcasting Company, Inc. and SmithKline Beecham, PLC.
 
     The Company was founded in February 1997 by executives with extensive
experience at major consulting firms and industry-leading companies. The Company
has focused on building its portfolio of practice areas through selective
acquisitions and internal growth to provide a balanced perspective on the
problems and issues facing its clients in today's competitive environment. Since
inception, the Company has built competencies in its four practice areas
primarily through acquisitions. Each Acquired Company maintains a business focus
which complements the businesses of the other Acquired Companies, enabling
synergies to be realized across all of Nextera's practice areas.
 
     The Company's objective is to be a leading provider of consulting services
in its four practice areas. Nextera intends to achieve this objective by: (i)
expanding service offerings through selective acquisitions; (ii) leveraging
cross-selling opportunities to expand the scope of engagements; (iii) attracting
and retaining key personnel who will enhance and complement the Company's
service capabilities; (iv) building a common identity for the services the
Company provides by marketing the Nextera brand name; and (v) expanding
Nextera's international presence.
 
     The Company is a Delaware corporation and maintains its principal executive
office at One Cranberry Hill, Lexington, Massachusetts 02421. The Company's
telephone number is (781) 778-4400.

                                  RISK FACTORS
 
     The following risk factors should be considered carefully in addition to
the other information contained in this Prospectus before purchasing the shares
of Class A Common Stock offered hereby. This Prospectus contains forward-looking
statements that involve risks and uncertainties. The Company's actual results
could differ materially from those contained in the forward-looking statements.
Factors that may cause such differences include, but are not limited to, those
discussed below as well as those discussed elsewhere in this Prospectus.
 
     Limited Combined Operating History; Recent Acquisitions. Nextera was formed
in February 1997 and has grown substantially since its inception, principally
through the acquisitions of the Acquired Companies. Although the Acquired
Companies have been in operation for some time, the Company has a limited
history of combined operations. Consequently, the historical and pro forma
information herein may not be indicative of Nextera's financial condition and
future performance. There can be no assurances that the Company will not
encounter financial, managerial or other difficulties as a result of its lack of
combined operating history. Further, the success of Nextera's acquisitions will
depend on a number of factors, including the Company's ability to integrate the
businesses and operations of the Acquired Companies, to retain certain key
employees of the Acquired Companies and to preserve and expand the businesses
and operations of the Acquired Companies. There can be no assurance that Nextera
will be able to successfully integrate and operate the businesses of the
Acquired Companies or that the Company will not experience losses as a result of
these acquisitions. Failure to achieve the anticipated benefits of these
acquisitions or to successfully integrate the operations of the Acquired
Companies could materially adversely affect the business, operating results and
financial condition of the Company. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Business--Acquisitions."
 
     Management of Growth. Nextera has experienced a period of rapid growth that
has challenged, and will likely continue to challenge, the Company's managerial
and other resources. Since the Company's inception in February 1997 through
August 31, 1998, the number of consultants employed by the Company has increased
to 355 and the scope of Nextera's geographic coverage has expanded
significantly. Nextera intends to hire additional consultants through
acquisitions and its own recruiting efforts and expects its geographic coverage
to continue to grow in the future. The Company's success in managing its growth
will depend on its ability to continue to enhance its operating, financial and
management information systems and to recruit, develop, motivate and manage
effectively its expanding work force. For example, Nextera is in the process of
integrating a new financial reporting system, and any failure or significant
delay in achieving the integration of such system or complications with respect
to the change to such system could materially adversely affect the Company. In
addition, Nextera's future success will depend in large part on its ability to
continue to set rates and fees competitively and to maintain high employee
utilization rates and project quality, particularly if the average size or
number of the Company's projects increases. If Nextera is unable to manage
growth or new employees effectively or if its personnel are unable to achieve
anticipated performance or utilization levels, the Company's services, its
ability to retain key personnel, and its business, operating results and
financial condition could be materially adversely affected. There can be no
assurance that Nextera will be able to effectively manage its growth or that the
Company's business will continue to expand. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations," "Business--Growth
Strategy" and "--Human Resources."
 
     Risks Related to Acquisitions. Since its inception, Nextera has
significantly expanded through acquisitions and expects to pursue additional
acquisitions in order to enhance its service offerings and client base, expand
its geographic presence and obtain experienced consultants. The timing,
magnitude and success of the Company's acquisition efforts and the related
capital expenditures and commitments cannot be predicted. Nextera competes for
acquisitions with companies that have significantly greater financial and
management resources than the Company, which may lead to limited acquisition
opportunities for Nextera and may result in higher purchase prices or
transaction costs. There can be no assurance that the Company will be able to
integrate successfully any acquired businesses without substantial expense,
delays or other operational or financial costs or problems, including costs in
pursuing and negotiating with acquisition candidates, or that it will be able to
identify, acquire or profitably manage additional businesses or acquisitions.
Acquisitions may
                                        6
<PAGE>   8
 
involve certain risks, including significant diversion of management's
attention, failure to retain key acquired personnel, unanticipated events or
circumstances and legal liabilities. Client satisfaction or performance problems
at a single acquired firm could have a material adverse impact on the reputation
of Nextera as a whole. Further, there can be no assurance that the Company's
future acquired businesses will achieve expected results or generate anticipated
revenues or earnings. In order to pursue additional acquisitions, Nextera may
also require debt or equity financing that may not be available on terms
favorable to the Company, if at all, and may result in dilution to the holders
of Class A Common Stock. Nextera will be unable to account for future
acquisitions under the pooling-of-interests method of accounting. Accordingly,
the Company will be required to account for acquisitions under the purchase
method of accounting, which may result in substantial additional annual non-cash
amortization charges for goodwill and other intangible assets in Nextera's
statements of operations. In addition, the Company could be required to make
substantial cash payments related to any such acquisition. Any of these factors
could materially adversely affect Nextera's business, operating results and
financial condition. See "--Substantial Amount of Goodwill," "Management's
Discussion and Analysis of Financial Condition and Results of Operations,"
"Business--Growth Strategy" and "--Acquisitions."
 
     Attraction and Retention of Skilled Consultants. Because Nextera's business
involves the delivery of professional services and is labor-intensive, the
Company's success depends in large part upon its ability to attract, motivate
and retain highly skilled consultants. Qualified business consultants are in
great demand and are likely to remain a limited resource for the foreseeable
future. There can be no assurance that Nextera will be able to attract, motivate
and retain sufficient numbers of highly skilled consultants. Any inability to do
so could impair the Company's ability to effectively manage and complete its
client projects and to secure future client engagements, and as a result could
materially adversely affect Nextera's business, operating results and financial
condition. Because the Company has experienced growth principally through the
acquisitions of the Acquired Companies, substantially all of Nextera's current
consultants were initially hired by one of the Acquired Companies and not the
Company. There can be no assurance that these consultants will continue to be
satisfied with the culture or benefits of the Company or prospects for
advancement within Nextera. Further, even if the Company is able to expand the
number of qualified consultants, the resources required to attract, motivate and
retain such consultants may adversely affect Nextera's operating margins, which
could materially adversely affect the Company's business, operating results and
financial condition. To the extent that Nextera is unable to attract, motivate
or retain qualified consultants from among individuals currently legally
eligible to work in the United States, the Company may need to utilize foreign
labor under H-1B and other employment-related permits and visas granted by the
United States government. In the event that such visas are unavailable, either
due to a change in policy or law or a reduction in the number of such visas
granted, Nextera may be unable to attract or retain additional qualified
consultants or may incur unexpected substantial additional labor costs, any of
which could materially adversely affect the Company's business, operating
results and financial condition. See "Business--Human Resources."
 
     Control by Knowledge Enterprises, Inc.; Effect of Class B Common
Stock. After the Offering, Knowledge Enterprises will own           shares of
Class A Common Stock and           shares of Class B Common Stock, which
together will represent      % of the voting power of the outstanding Common
Stock. The Class A Common Stock entitles its holders to one vote per share and
the Class B Common Stock entitles its holders to ten votes per share, on all
matters submitted to a vote of Nextera's stockholders, including in connection
with the election of the Board of Directors. Accordingly, Knowledge Enterprises
will be able to elect all of the Company's directors, except for one director to
be elected in accordance with the terms of a stockholders agreement, and
determine the disposition of all matters submitted to a vote of Nextera's
stockholders, including mergers, transactions involving a change in control of
the Company and other corporate transactions and the terms thereof. Such control
by Knowledge Enterprises could materially adversely affect the market price of
the Class A Common Stock or delay or prevent a change in control of Nextera.
There can be no assurance that conflicts of interest between Knowledge
Enterprises and the Company will not arise or that any such conflict of interest
will be resolved in a manner favorable to Nextera, including potential
competitive business activities, indemnity arrangements, registration rights,
sales or distributions by Knowledge Enterprises of Nextera's Class A Common
Stock and Class B Common Stock and the exercise by Knowledge Enterprises of its
ability to control the management and affairs of the Company.
                                        7
<PAGE>   9
 
Knowledge Enterprises is controlled by Knowledge Universe. The Company believes
that through ownership or voting control of various intermediate entities,
Lawrence J. Ellison, Michael R. Milken and Lowell J. Milken may each be deemed
to have the power to direct the voting and disposition of, and to share
beneficial ownership of, any shares of Common Stock owned by Knowledge
Enterprises. Any change in Nextera's relationship with Knowledge Enterprises or
Knowledge Universe could materially adversely affect the Company's business,
operating results and financial condition. See "The Company--Transfer to
Knowledge Enterprises," "Management--Board of Directors," "Certain
Transactions," "Principal Stockholders" and "Description of Capital Stock."
 
     Variability and Seasonality of Quarterly Operating Results. Nextera may
experience fluctuations in its future quarterly operating results. Variations in
the Company's net revenues and operating results from quarter-to-quarter may be
caused by such factors as the number of active client projects, termination of
major client projects, the number of business days in a quarter, hiring,
integration and utilization of consultants and other employees, the mix and
timing of client projects, re-evaluation of progress on and completion of client
projects, variations in utilization rates and average billing rates for
consultants, the accuracy of estimates of resources required to complete ongoing
projects, the integration of acquired entities, and the length of Nextera's
sales cycle. Because a relatively high percentage of the Company's expenses is
relatively fixed, a variation in the number or timing of client projects,
particularly at or near the end of any quarter, may cause significant variations
in operating results from quarter-to-quarter and could result in losses to
Nextera for any particular fiscal period. Events such as write-offs of
uncollectable accounts, the unanticipated termination of a major project or the
completion during a single quarter of several major client projects without
deploying consultants to new engagements could result in the Company's
underutilization of consultants which could, in turn, materially adversely
affect Nextera's business, operating results and financial condition. To the
extent that increases in the numbers of consultants are not followed by
corresponding increases in net revenues, the operating results of the Company
could be materially adversely affected. In addition, it is difficult for Nextera
to forecast the timing of revenues because project cycles depend on factors such
as the size and scope of consulting projects and circumstances specific to each
client. Because the Company's consultants only generate revenues when they are
engaged on client projects, Nextera's operating results are adversely affected
when its consultants cannot perform services for clients due to vacations, sick
days, holidays, inclement weather, training schedules or other reasons. In
particular, the Company can be expected to generate a smaller proportion of its
net revenues and realize lower operating income during the fourth quarter of the
year due to the number of holidays in that quarter. Given the foregoing factors,
Nextera believes that quarter-to-quarter comparisons of its operating results
are not necessarily meaningful and that the results for one quarter should not
be relied upon as an indication of future performance. Demand for Nextera's
services is significantly affected by the general level of economic activity.
When economic activity slows, clients may delay or cancel plans that involve the
hiring of consultants. The Company is unable to predict the level of economic
activity at any particular time, and fluctuations in the general economy could
materially adversely affect Nextera's business, operating results and financial
condition. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations."
 
     Substantial Amount of Goodwill. As of June 30, 1998, on a pro forma basis
reflecting the Sibson Acquisitions, the Company's intangible assets, net of
accumulated amortization, were approximately $81.2 million. As a result of the
acquisitions of the Acquired Companies, intangible assets are being amortized by
Nextera on a straight-line basis over 5 years for intangibles relating to
personnel and over 40 years for all other intangibles, including goodwill.
Future acquisitions by Nextera are expected to result in additional goodwill and
intangible assets. The amount amortized in a particular period constitutes a
non-cash expense that reduces the Company's net income. In accordance with
Statement of Financial Accounting Standards No. 121, Accounting for the
Impairment of Long-Lived Assets to be Disposed Of ("SFAS No. 121"), the Company
periodically evaluates the recoverability of goodwill by reviewing the
anticipated undiscounted future cash flows from operations and comparing such
cash flows to the carrying value of the associated goodwill. If goodwill becomes
impaired, Nextera will be required to write down the carrying value of the
goodwill and incur a related charge to its income. A write down of goodwill
would result in a reduction in net income which could materially adversely
affect Nextera's business, operating results and financial condition. See
"--Risks

Related to Acquisitions," "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business--Acquisitions."
 
     Concentration of Net Revenues. Nextera has in the past derived, and may in
the future derive, a significant portion of its net revenues from a relatively
limited number of clients. For example, for the year ended December 31, 1997 and
for the six months ended June 30, 1998, on a pro forma basis, the Company's ten
largest clients accounted for approximately 29%, and 36% of its net revenues,
respectively. For the year ended December 31, 1997 and for the six months ended
June 30, 1998, on a pro forma basis, the Company's largest client during such
period accounted for approximately 8% and 7% of Nextera's net revenues,
respectively. There can be no assurance that these significant clients will
continue to engage the Company for additional projects or do so at the same
revenue levels or that the portion of Nextera's net revenues attributable to a
relatively limited number of clients will not increase in the future or that the
Company will not experience concentration of receivables. The loss of any such
client, or a reduction in the scope of engagements undertaken for such client,
could materially adversely affect Nextera's business, operating results and
financial condition. Clients engage the Company on a project-by-project basis,
often without a written contract, and a client can generally terminate an
engagement with little or no notice to Nextera and without penalty. Further,
clients in the financial services, manufacturing and health care industries
accounted for approximately 23%, 17% and 11%, respectively, of Nextera's pro
forma net revenues for the year ended December 31, 1997. Any economic conditions
or other factors adversely affecting any of the foregoing industries or any
increase in the size or number of the Company's competitors within these
industries could materially adversely affect Nextera's business, operating
results and financial condition. See "--Absence of Written Contracts,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business--Clients and Representative Engagements."
 
     Dependence on Key Personnel. The Company's success is highly dependent upon
the efforts, abilities, business generation capabilities and project execution
skills of its senior consulting executives and other key personnel. The loss of
the services of any of these persons for any reason could materially adversely
affect Nextera's business, operating results and financial condition, including
its ability to secure and complete engagements. There can be no assurance that
the Company will be able to retain these persons or to attract suitable
replacements or additional personnel if required. In addition, if one or more of
Nextera's key personnel resigns from the Company to join a competitor or to form
a competing business, any resulting loss of existing or potential clients to any
such competitor could materially adversely affect Nextera's business, operating
results and financial condition. In the event of the loss of any such personnel,
there can be no assurance that the Company would be able to prevent the
unauthorized disclosure or use of its technical knowledge, practices or
procedures by such personnel. Nextera generally does not maintain key person
life insurance coverage for employees. See "Business--Human Resources" and
"Management."
 
     Project Risks; Fixed Price Contracts. The Company's client engagements
often involve projects that are critical to the operation of a client's business
and provide benefits that may be difficult to quantify. Nextera's failure or
inability to meet a client's expectations in the performance of its services
could result in a client's refusal to pay or give rise to claims against the
Company or damage Nextera's reputation, any of which could materially adversely
affect its business, operating results and financial condition. There can be no
assurance that the Company will not fail to satisfy certain clients'
expectations. Nextera has undertaken and expects in the future to undertake
certain projects under fixed-price or capped-fee billing arrangements, which are
distinguishable from the Company's principal method of utilizing time and
materials billing arrangements. On a pro forma basis, fixed-price or capped-fee
billing arrangement projects accounted for approximately 11% and 19%, of
Nextera's net revenues for the year ended December 31, 1997 and for the six
months ended June 30, 1998, respectively. The failure of Nextera to complete
such fixed-price or capped-fee projects within budget or below the cap would
expose the Company to risks associated with potentially unrecoverable cost
overruns, which could materially adversely affect Nextera's business, operating
results and financial condition. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
     Absence of Written Contracts. Nextera derives a significant portion of its
net revenues from client projects involving significant dollar values.
Accordingly, the cancellation, delay or significant reduction in the
 
                                        9
<PAGE>   11
 
scope of a large engagement could materially adversely affect the Company's
business, operating results and financial condition. Clients engage the Company
on a project-by-project basis, often without a written contract, and a client
can generally terminate an engagement with little or no notice to Nextera and
without penalty. As a result, Nextera believes that the number of clients or the
number and size of its existing projects are not reliable indicators or measures
of future net revenues. The Company has in the past provided, and is likely in
the future to provide, services to clients without a written contract. When a
client defers, modifies or cancels a project, Nextera must be able to rapidly
deploy its consultants to other projects in order to minimize the
underutilization of employees and the resulting adverse impact on operating
results. In addition, the Company's operating expenses are relatively fixed and
cannot be reduced on short notice to compensate for unanticipated variations in
the number or size of projects in progress. As a result, any termination,
significant reduction or modification of its business relationships with any of
its significant clients or with a number of smaller clients could materially
adversely affect Nextera's business, operating results and financial condition.
 
     Competition. The consulting services industry includes a large number of
competitors, is subject to rapid change and is highly competitive. Nextera
believes that its ability to compete depends in part on a number of factors
outside of its control, including the ability of its competitors to hire, retain
and compensate consultants, offer lower-priced services, respond to client
requirements, and develop advanced services or technology. Nextera's primary
competitors include participants from a variety of market segments, including
general management consulting companies, boutique management consulting firms
that provide specialized services or focus on certain industries, "Big Five" and
other accounting firms, systems consulting and implementation firms, application
software firms, service groups of computer equipment companies, outsourcing
companies, and systems integration companies. Many of these competitors have
significantly greater financial, technical, and marketing resources, and greater
name recognition than Nextera. In addition, many of these competitors have been
operating for a significantly longer period of time than the Company and have
established long-term client relationships. Nextera also competes with its
clients' internal resources, particularly where the resources represent a fixed
cost to the client. Such competition may impose additional pricing pressures on
Nextera. In addition, Nextera faces intense competition in its efforts to
recruit and retain qualified consultants. There can be no assurance that the
Company will be able to compete successfully with its existing competitors or
any new competitors. See "Business--Competition."
 
     Foreign Operations. Nextera derived approximately 8% and 6% of its net
revenues on a pro forma basis from clients outside of the United States for the
year ended December 31, 1997 and the six months ended June 30, 1998,
respectively. The Company has engaged in projects in Canada and the United
Kingdom and intends to continue to seek an increasing number of foreign
engagements. One of the components of Nextera's growth strategy is to expand its
international presence and seek additional business outside the United States.
Nextera's international business operations are and will be subject to a number
of risks, including difficulties in managing foreign operations, enforcing
agreements and collecting receivables through foreign legal systems; longer
payment cycles; fluctuations in the value of foreign currencies; and unexpected
regulatory, economic or political changes in foreign markets. The relationship
between non-dollar denominated revenues and dollar denominated expenses may
subject the Company to significant foreign exchange risks. In addition, Nextera
may in the future acquire an interest in entities that operate in countries
where the repatriation or conversion of currency is restricted. There can be no
assurance that these factors will not materially adversely affect the Company's
business, operating results and financial condition. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
"Business--Growth Strategy."
 
     Rapid Technological Change. Nextera's success will depend in part on its
ability to develop business consulting and strategic information technology
solutions that keep pace with continuing changes in information processing
technology and the effect of such changes on client needs and preferences. Part
of the Company's strategy is to focus on business performance solutions, which
include strategic/knowledge management systems and enabling technologies. There
can be no assurance that Nextera will be successful in adequately addressing
developments in IT on a timely basis or that, if these developments are
addressed, the Company will be successful in the marketplace. In addition, there

tive or obsolete. The Company's failure to identify or address these
developments could materially adversely affect Nextera's business, operating
results and financial condition.
 
     Year 2000 Risks. Many currently installed computer systems are coded to
accept only two digit entries in the date code field. These date code fields
need to be modified or upgraded to accept four digit entries to distinguish 21st
century dates from 20th century dates. Many organizations are expending
significant resources to modify or upgrade their computer systems for such "Year
2000" compliance. These expenditures may result in reduced funds available to
purchase the types of services offered by the Company as resources that might
otherwise be directed towards the purchase of outside consulting services are
utilized for Year 2000 compliance. Any such reduction in the purchase of the
types of services offered by Nextera could materially adversely affect the
Company's business, operating results and financial condition. Nextera has
completed an assessment of its computer systems for Year 2000 compliance.
Although the Company does not believe that the costs of addressing Year 2000
compliance issues with respect to Nextera's own systems will materially
adversely affect its business, operating results or financial condition, the
Company depends on smooth and timely interactions with its vendors, clients and
other third parties. Any unexpected costs or disruption in the operations or
activities of such vendors, clients or other third parties as a result of Year
2000 compliance issues within such entities could materially adversely affect
Nextera's business, operating results and financial condition.
 
     The Company has in the past and may in the future perform services related
to the planning, implementation and testing of Year 2000 compliance work for its
clients. Failure to timely or accurately perform these services could cause a
client to experience failures of one or more key systems or result in
miscalculations causing material disruptions of one or more of a client's
operations, including an inability to process transactions or engage in business
activities. A claim for product or service liability brought against Nextera
could result in substantial cost to the Company and divert management's
attention from Nextera's operations, which could materially adversely affect the
Company's business, operating results and financial condition.
 
     Anti-Takeover Effect of Certain Charter and Bylaw Provisions. The Company's
Amended and Restated Certificate of Incorporation ("Certificate of
Incorporation") and Bylaws, as well as Delaware corporate law, contain certain
provisions that could have the effect of delaying, deferring or preventing a
change in control of Nextera. These provisions could limit the price that
certain investors might be willing to pay in the future for shares of the Class
A Common Stock. The Certificate of Incorporation authorizes the Company's Board
of Directors to issue shares of Preferred Stock of Nextera, in one or more
series, and to establish the rights and preferences (including the
convertibility of such shares of Preferred Stock into shares of Class A Common
Stock) of any series of Preferred Stock so issued. Such provisions could
diminish the opportunities for a stockholder to participate in tender offers,
including tender offers at a price above the then current market value of the
Class A Common Stock. Such provisions also may inhibit fluctuations in the
market price of the Class A Common Stock that could result from takeover
attempts. Other provisions impose various procedural and other requirements that
could make it difficult for stockholders to take certain corporate actions. In
particular, the Certificate of Incorporation provides that any action required
or permitted to be taken by stockholders of Nextera must be effected at a duly
called annual or special meeting of stockholders and may not be effected by any
consent in writing, and the Bylaws require stockholders to comply with special
advance notice procedures in order to make a proposal or director nomination
which such stockholder desires to present at any annual or special meeting of
stockholders. Special meetings of stockholders may be called only by the Board
of Directors, the Chairman of the Board, or the President of the Company. See
"--Control by Knowledge Enterprises, Inc.; Effect of Class B Common Stock" and
"Description of Capital Stock."
 
     Intellectual Property Rights. Nextera's success is dependent in part upon
certain methodologies and other proprietary intellectual property rights.
Nextera relies upon a combination of nondisclosure, confidentiality, license and
other contractual arrangements and trade secret, copyright and trademark laws to
protect its proprietary rights and the proprietary rights of third parties from
whom Nextera licenses intellectual property. In addition, Nextera generally
limits the distribution of its proprietary information. There can be no
assurance, however, that the steps taken by Nextera to protect its intellectual
property rights will be adequate to deter misappropriation of proprietary
information or that the Company will be able to detect unauthorized use and
                                       11
<PAGE>   13
 
take appropriate steps to enforce its intellectual property rights or that
competitors will not be able to develop similar or functionally equivalent
methodologies. Furthermore, effective copyright and trade secret protection may
be unavailable or limited in certain foreign countries, and no assurance can be
given that foreign copyright and trade secret laws will adequately protect the
Company's intellectual property rights. Although Nextera believes that its
services do not infringe on the intellectual property rights of others and that
it has all rights necessary to utilize the intellectual property employed in its
business, there can be no assurance that Nextera's employees will not
misappropriate the intellectual property of others. Accordingly, the Company is
subject to the risk of claims alleging infringement of third-party intellectual
property rights. Any such claims could require Nextera to spend significant sums
in litigation, pay damages, develop non-infringing intellectual property or
acquire licenses to the intellectual property that is the subject of asserted
infringement, any of which could materially adversely affect the Company's
business, operating results and financial condition. The Company presently holds
no patents or registered copyrights.
 
     No Prior Public Market; Possible Volatility of Stock Price. Prior to the
Offering, there has been no public market for the Class A Common Stock.
Consequently, the initial public offering price per share will be determined by
negotiations between Nextera and the representatives of the Underwriters and may
not be indicative of the market price of the Class A Common Stock after the
Offering. See "Underwriting" for a discussion of factors to be considered in
determining the initial public offering price per share. Application has been
made for quotation of the Class A Common Stock on the Nasdaq National Market;
however, there can be no assurance that an active trading market will develop
and be sustained after the Offering. In the absence of a public trading market,
investors may be unable to liquidate their investments in the Company. The
market price of the Class A Common Stock may fluctuate substantially due to a
variety of factors, including quarterly fluctuations in results of operations,
adverse circumstances affecting the introduction or market acceptance of new
services offered by Nextera, announcements of new services by competitors,
changes in earnings estimates by analysts, changes in accounting principles,
sales of Class A Common Stock or Class B Common Stock by existing holders, the
depth and liquidity of the market for Class A Common Stock, loss of key
personnel, general market conditions and other factors. Equity securities of
entities with businesses similar to the Company's are subject to greater
volatility than the general market. In addition, the stock market from time to
time has experienced broad price and volume fluctuations that often have been
unrelated or disproportionate to the operating performance of individual
companies. These broad market fluctuations, as well as shortfalls in operating
results as compared to securities analysts' expectations or changes in such
analysts' projections or recommendations, and general economic market
conditions, may materially and adversely affect the market price of the Class A
Common Stock. In the past, following periods of volatility in the market price
of a company's securities, class action litigation has often been instituted
against such a company. Any such litigation brought against the Company could
result in substantial costs and a diversion of management's attention and
resources, which could materially adversely affect Nextera's business, operating
results and financial condition.
 
     Dilution. Purchasers of shares of Class A Common Stock in the Offering will
experience immediate and substantial dilution in the pro forma net tangible book
value per share of Class A Common Stock after the Offering. To the extent
outstanding options to purchase Class A Common Stock are exercised, there will
be further dilution. There can be no assurance that the Company will not require
additional funds to support its working capital requirements or for other
purposes, in which case Nextera may seek to raise such additional funds through
public or private debt or equity financing or from other sources. There can be
no assurance that such additional financing will be available or that, if
available, such financing will be obtained on terms favorable to the Company and
would not result in additional dilution of Nextera's stockholders. See
"Dilution."
 
     Shares Eligible for Future Sale; Registration Rights Agreement. Sales of
significant amounts of Common Stock in the public market after the Offering or
the perception that such sales will occur could materially adversely affect the
market price of the Class A Common Stock or the future ability of the Company to
raise capital through an offering of its equity securities. Of the shares of
Common Stock to be outstanding upon completion of the Offering, the
               shares offered hereby will be eligible for
 
                                       12
<PAGE>   14
 
immediate sale in the public market without restriction unless such shares are
purchased by "affiliates" of Nextera within the meaning of Rule 144 ("Rule 144")
under the Securities Act.
 
     The remaining                shares of Common Stock (including Class A
Common Stock issuable upon exchange of the Exchangeable Shares) held by existing
stockholders upon completion of the Offering will be "restricted securities" as
that term is defined in Rule 144. Restricted securities may be sold in the
public market only if registered or if they qualify for an exemption from
registration under the Securities Act. Directors, officers and certain
stockholders of the Company holding an aggregate of                shares of
Class A Common Stock and                shares of Class B Common Stock have
agreed that they will not sell, directly or indirectly, any Common Stock,
subject to certain exceptions, without the prior consent of Donaldson, Lufkin &
Jenrette Securities Corporation ("DLJ") for a period of 180 days from the date
of this Prospectus (the "Lock-up Agreements"). In addition, Nextera's
Certificate of Incorporation provides that each holder of Common Stock, other
than the holders of the shares of Class A Common Stock acquired in the Offering,
agrees not to sell, directly or indirectly, any Common Stock, subject to certain
exceptions, without the prior consent of DLJ for a period of 180 days from the
date of this Prospectus. Subject to these Lock-up Agreements and the foregoing
provisions of the Company's Certificate of Incorporation, additional shares of
Class A Common Stock (including Class A Common Stock issuable upon conversion of
Class B Common Stock and the exchange of the Exchangeable Shares) will be
available for sale in the public market (subject in certain circumstances to
compliance with certain volume and other restrictions under Rule 144) as
follows: (i)                shares will be eligible for sale 180 days after the
date of this Prospectus; and (ii)                shares will become eligible
thereafter for sale under Rule 144 upon the expiration of the applicable
one-year holding periods. In addition, if the restrictions of the Lock-up
Agreements described above and the foregoing provisions of the Company's
Certificate of Incorporation were waived in full on the date hereof: (i)
               shares of Common Stock would become eligible for sale in the
public market from and after the date of this Prospectus; and (ii)
               shares of Common Stock would be eligible for sale in the public
market 90 days after the date of this Prospectus.
 
     Following the date of this Prospectus, Nextera intends to register on one
or more registration statements on Form S-8 approximately                shares
of Class A Common Stock issuable under the 1998 Equity Participation Plan. Of
the                shares of Class A Common Stock issuable under the 1998 Equity
Participation Plan,           shares were subject to outstanding options as of
September 1, 1998, of which                will be exercisable at the time of
the Offering.
 
     Upon completion of the Offering, the holders of           shares of Class A
Common Stock and shares of Class B Common Stock (after conversion to Class A
Common Stock) will be entitled to certain registration rights with respect to
such shares. If such holders, by exercising their registration rights, cause a
large number of shares of Class A Common Stock to be registered and sold in the
public market, such sales could materially adversely affect the market price of
the Class A Common Stock. In addition, if the Company is required, pursuant to
such registration rights, to include shares held by such persons in a
registration statement which Nextera files to raise additional capital, the
inclusion of such shares could adversely affect the Company's ability to raise
needed capital. See "Management--Employee Benefit Plans," "Principal
Stockholders" and "Shares Eligible for Future Sale."

                                  THE COMPANY
 
     The following discussion summarizes the Company's formation and certain
other significant events relating to its capital structure prior to the
Offering. For additional related information see "Management's Discussion and
Analysis of Financial Condition and Results of Operation--Liquidity and Capital
Resources" and "Certain Transactions."
 
     Formation. The Company was formed on February 26, 1997 as Education
Technology Consulting, L.L.C. and renamed Nextera Enterprises, L.L.C. on April
11, 1997. The Company will operate as a Delaware limited liability company until
the consummation of the Exchange Transaction (as defined below). The initial
members of Nextera LLC were Nextera Enterprises Holdings, L.L.C. (formerly
Education Technology Consulting Holdings, LLC) ("NEH") and EDU, L.L.C. ("EDU"),
each of which was an affiliate of Knowledge Universe. In connection with the
commencement of their respective employment, Gresham T. Brebach, Jr., the
Company's President, Chief Executive Officer and Chairman of the Board of
Directors, Ronald K. Bohlin, the Company's Chief Operating Officer and Director,
Michael P. Muldowney, the Company's Chief Financial Officer, Debra I. Bergevine,
the Company's Vice President, Marketing, and certain additional individuals
became members of NEH. See "Certain Transactions--Investments in the Company."
 
     Recapitalization. Effective as of April 30, 1998, approximately $48.0
million of Nextera LLC's contributed capital was redesignated as debt in the
form of (i) a debenture dated March 20, 1997 with a principal amount of $23.0
million, which matures on May 1, 2002 and bears interest at a rate of 10% per
annum (the "March Debenture") and (ii) a debenture dated January 5, 1998 with a
principal amount of $25.0 million, which matures on May 1, 2002 and bears
interest at a rate of 10% per annum (the "January Debenture" and together with
the March Debenture, the "Debentures"), and NEH was liquidated and dissolved. In
connection with these transactions, the former members of NEH became members of
Nextera LLC and interests in the January Debenture and March Debenture were
distributed to Knowledge Universe, Messrs. Brebach, Bohlin and Muldowney, Ms.
Bergevine and certain other employees of Nextera LLC. The March Debenture is
subordinated to the January Debenture. The interest on the principal amount of
the Debentures is deemed to have begun to accrue on the date the respective
redesignated capital contributions were originally contributed to Nextera LLC.
See "Use of Proceeds" and Note 9 of Notes to the Company's Consolidated
Financial Statements.
 
     Transfer to Knowledge Enterprises. Effective August 5, 1998, Knowledge
Universe contributed all of its Class A Common Units and Class B Common Units of
Nextera LLC to Knowledge Universe, Inc. ("KU, Inc.") in exchange for shares of
its capital stock. Effective August 7, 1998, KU, Inc. and EDU contributed all of
their Class A Common Units and Class B Common Units of Nextera LLC to Knowledge
Enterprises in exchange for capital stock of Knowledge Enterprises (the "KE
Transaction"). See "Principal Stockholders."
 
     Exchangeable Preference Shares. In connection with the Sibson Acquisitions,
Nextera LLC formed Sibson Acquisition Co., a wholly owned Canadian subsidiary,
which issued Exchangeable Preference Shares ("Exchangeable Shares") to the
holders of capital stock of Sibson Canada, Inc. The holders of Exchangeable
Shares may exchange such shares at any time for an aggregate of      shares of
Class A Common Stock. The Exchangeable Shares are designed to provide an
opportunity for the shareholders of Sibson Canada, Inc. to achieve a Canadian
tax deferral in certain circumstances. The holders of Exchangeable Shares are
entitled to dividend and other rights equivalent to shares of Class A Common
Stock but are not entitled to vote on matters submitted to the holders of Class
A Common Stock until such time as the holders of Exchangeable Shares exchange
such shares for Class A Common Stock.
 
     Exchange Transaction. Prior to the Offering, all of the members of Nextera
LLC (the "Members") other than the two entities that owned Sibson & Company,
L.P. prior to its acquisition by Nextera LLC (together, the "Sibson Entities")
will contribute all of their membership interests in Nextera LLC to Nextera in
exchange for Common Stock. The percentage interests and classes of Common Stock
received by each Member (other than the Sibson Entities) will correspond to the
percentage interests and classes of the Nextera LLC membership interests held by
such Member. Each Member that contributes Class A Common Units of Nextera LLC
will receive shares of Class A Common Stock and each member that contributes
Class B Common Units of Nextera LLC will receive shares of Class B Common Stock.
Contemporaneous with the exchange of membership interests of Nextera LLC for
Common Stock, the shareholders of the Sibson Entities will contribute all of the
issued and outstanding common stock of the Sibson Entities to Nextera in
exchange for shares of Class A Common Stock. The aggregate percentage interests
of Class A Common Stock that will be received by the shareholders of the Sibson
Entities will correspond to the percentage interests of Class A Common Units in
Nextera LLC held by the Sibson Entities (the collective contributions of
membership interests in Nextera LLC and capital stock of the Sibson Entities to
Nextera are referred to as the "Exchange Transaction"). After the Exchange
Transaction, the Company will hold directly 85.9% of the membership interests in
Nextera LLC and, indirectly through the Sibson Entities, will hold the remaining
14.1%. See "Principal Stockholders."

                                USE OF PROCEEDS
 
     The net proceeds to Nextera from the sale of the                     shares
offered by the Company pursuant to the Offering are estimated to be
approximately $     million ($     million if the Underwriters' over-allotment
option is exercised in full), at an assumed offering price of $     per share
after deducting the estimated underwriting discounts and commissions and
Offering expenses payable by the Company. The principal purposes of the Offering
are to create a public market for the Class A Common Stock, enhance Nextera's
ability to use its Class A Common Stock as a means of attracting, motivating and
retaining key employees, facilitate the Company's future access to public equity
markets, repay indebtedness, and obtain additional working capital. Nextera
intends to use the net proceeds from the Offering as follows:
 
          (i) approximately $     million to repay outstanding principal and
     interest under a $40 million revolving credit facility entered into
     effective August 31, 1998 (the "Bridge Loan") which bears interest at the
     rate of LIBOR plus 450 basis points (10.2% as of August 31, 1998) per
     annum, and matures on February 28, 1999. The Company borrowed $38.0 million
     under the Bridge Loan to finance the Sibson Acquisitions. See "Management's
     Discussion and Analysis of Financial Condition and Results of
     Operations--Liquidity and Capital Resources" and "Underwriting."
 
          (ii) approximately $     million to repay outstanding principal and
     interest on the March Debenture and approximately $     million to repay
     outstanding principal and interest on the January Debenture. All of the
     interests in the Debentures are held by Knowledge Universe, Messrs.
     Brebach, Bohlin and Muldowney, Ms. Bergevine, and two other employees of
     Nextera. The indebtedness associated with the Debentures was incurred to
     finance acquisitions and for general working capital purposes. See "The
     Company--Recapitalization" and "Certain Transactions--Investments in the
     Company."
 
          (iii) approximately $       to pay accrued management fees to
     Knowledge Universe. See "Certain Transactions--Management Agreement."
 
          (iv) the remaining net proceeds for general corporate purposes.
 
     Although Nextera examines potential acquisition opportunities from time to
time, the Company has no current plans, commitments, agreements or
understandings with respect to any material acquisitions or investments as of
the date of this Prospectus, and no portion of the net proceeds has been
allocated for any specific material acquisition or investment. Pending such
uses, Nextera intends to invest the net proceeds from the Offering in
short-term, investment-grade, interest-bearing securities. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources."
 
                                DIVIDEND POLICY
 
     Nextera has never declared or paid any cash dividends on its capital stock.
The Company currently intends to retain all future earnings, if any, for use in
the operation and development of its business and, therefore, does not expect to
declare or pay any cash dividends on its Common Stock in the foreseeable future.
The payment of dividends in the future, if any, will be at the discretion of the
Board of Directors.

                                    DILUTION
 
     As of June 30, 1998, the pro forma net tangible book value of Nextera was
$     , or $     per share of Common Stock. Pro forma net tangible book value
per share gives effect to the Sibson Acquisitions and is equal to the amount of
total pro forma tangible assets less total pro forma liabilities, divided by the
total pro forma number of shares of Common Stock outstanding. After giving
effect to the sale of the           shares of Class A Common Stock offered
hereby at an assumed initial public offering price of $     per share, and after
deducting the estimated underwriting discounts and commissions and Offering
expenses payable by the Company, the pro forma net tangible book value of
Nextera as of June 30, 1998 would have been $          , or $     per share of
Common Stock. This represents an immediate increase in pro forma net tangible
book value of $     per share of Common Stock to existing stockholders and an
immediate dilution of $     per share of Common Stock to new stockholders. The
following table illustrates this dilution on a per share basis:

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
     The following section of this Prospectus contains certain forward-looking
statements that involve substantial risks and uncertainties. When used in this
section, the words "anticipate," "believe," "estimate," and "expect" and similar
expressions as they relate to the Company or its management are intended to
identify such forward-looking statements. Nextera's actual results, performance
or achievements could differ materially from the results, performance or
achievements expressed in, or implied by, these forward-looking statements.
Factors that could cause or contribute to such differences include those
discussed in "Risk Factors" and elsewhere in this Prospectus.
 
OVERVIEW
 
     Nextera Enterprises, Inc. provides leading-edge business strategy,
operations improvement, organizational design and IT consulting services
primarily to Fortune 500 and other multinational companies. The Company provides
services in four practice areas, which enables it to offer a breadth and balance
of services that assist clients in achieving enhanced business performance by
anticipating and addressing their complex, multi-disciplinary consulting needs.
By developing dynamic business strategies and high performance business
processes and enhancing organizational effectiveness, the Company helps clients
identify and examine business problems and implement the strategic,
organizational and operational responses needed to solve such problems and
sustain performance improvement.
 
     Nextera was founded in February 1997 and has focused on building its
portfolio of practice areas primarily through selective acquisitions and
internal growth. The Company has pursued an acquisition strategy that has
resulted in the acquisitions of the Acquired Companies. The Company's results of
operations have been, and will continue to be, affected by substantial annual
non-cash amortization charges for goodwill as a result of these acquisitions
being accounted for under the purchase method of accounting. Nextera will be
unable to account for future acquisitions under the pooling-of-interests method
of accounting. Accordingly, the Company will be required to account for
acquisitions under the purchase method of accounting, which may result in
substantial additional annual non-cash amortization charges for goodwill and
other intangible assets in Nextera's statements of operations. Intangible assets
are being amortized by Nextera on a straight-line basis over 5 years for
intangibles relating to personnel and over 40 years for all other intangibles,
including goodwill. In accordance with SFAS No. 121, the Company will
periodically evaluate whether recent events and circumstances have occurred that
indicate the acquired goodwill may warrant revision.
 
     Nextera is affiliated with Knowledge Universe and Knowledge Enterprises and
from time to time has been engaged on an arm's-length basis to provide
consulting services for Knowledge Universe and its affiliates. The Company
expects that it may also be engaged to provide such services in the future. See
"Certain Transactions--Engagement of the Company by Knowledge Universe or its
Affiliates." Nextera expects to benefit from its association with Knowledge
Universe and Knowledge Enterprises through increased access to prospective
client contacts and other business opportunities and the potential ability of
Knowledge Universe and Knowledge Enterprises to enhance the Company's market
exposure, although there can be no assurance that these expected benefits will
be realized.
 
     The Company generates net revenues by providing business and IT consulting
services primarily under time and materials, fixed-price or capped-fee billing
arrangements. Under time and materials billing arrangements, revenues are
recognized as the services are performed. Revenues on fixed-price and capped-fee
contracts are recognized using the percentage of completion method of accounting
and are adjusted monthly for the cumulative impact of any revision in estimates.
The Company determines the percentage of completion of its contracts by
comparing costs incurred to date to total estimated costs. Contract costs
include all direct labor and expenses related to the contract performance. On a
pro forma basis, fixed price or capped-fee billing arrangements accounted for
approximately 11.0% and 19.0% of Nextera's net revenues for the year ended
December 31, 1997 and for the six months ended June 30, 1998, respectively. See
"Risk Factors--Project Risks; Fixed Price Contracts." The Company believes that
the majority of its work will continue to be performed under time and materials
billing arrangements. Net revenues exclude reimbursable expenses
 
                                       19
<PAGE>   21
 
charged to clients. The Company typically bills on a monthly basis to monitor
client satisfaction and manage its outstanding accounts receivable balances.
Substantially all of the Company's net revenues are derived from clients located
in the United States and Canada. The Company's 10 largest clients accounted for
approximately 29.1% and 36.1% of pro forma net revenues for the year ended
December 31, 1997 and for the six months ended June 30, 1998, respectively. For
the year ended December 31, 1997 and the six months ended June 30, 1998, none of
the Company's clients individually accounted for 10% or more of the Company's
pro forma net revenues. See "Risk Factors--Concentration of Revenues."
 
     Gross profit is derived from net revenues less the cost of revenues, which
includes salaries, bonuses and benefits paid to consultants. Nextera's financial
performance is primarily based upon billing margin (billable daily rate less the
consultant's daily cost) and personnel utilization rates (billable days divided
by paid days). The Company monitors its engagements to manage billing and
utilization rates. Because most of the Company's engagements are billed on a
time and materials basis, increases in its cost of revenues are generally passed
along to the Company's clients. Generally, clients are billed for expenses
incurred by Nextera on the clients' behalf. In addition, Nextera closely
monitors and attempts to control expenses that are not passed through to its
clients. Incentive compensation expenses paid to consultants have a large
variable component relating to net revenues and profit and, therefore, vary
based upon the Company's ability to achieve its operating objectives.
 
     Selling, general and administrative expenses consist of salaries and
benefits of certain senior management and other administrative personnel and
training, marketing and promotional costs. These expenses are associated with
the Company's development of new business and with the Company's management,
finance, recruiting, marketing and administrative activities. Incentive
compensation expenses for certain senior management also have a significant
variable component relating to net revenues and profit and, therefore, vary
based upon the Company's ability to achieve its operating objectives.
 
     The Company's income tax rates may vary from the federal statutory rate of
34% predominately due to nondeductible goodwill amortization, the utilization of
various net operating loss carryforwards, state and local taxes and
nondeductible meal expenses. As of June 30, 1998, Symmetrix, Inc. ("Symmetrix")
had net operating loss carryforwards of approximately $5.8 million which arose
principally as a result of disqualifying dispositions of Symmetrix' previously
outstanding stock options. As a result of the ownership change of Symmetrix due
to its acquisition by the Company, these net operating losses are subject to
limitations under the Internal Revenue Code. See Note 6 of Notes to the
Company's Consolidated Financial Statements.
 
ACQUISITIONS
 
     All acquisitions completed by Nextera have been accounted for under the
purchase method of accounting. Accordingly, the historical Consolidated
Financial Statements of the Company included in this Prospectus include
operating results of the Acquired Companies only from the effective date of each
respective acquisition and are not necessarily indicative of the future
financial condition or results of operations of the Company.

     The following table sets forth, for periods indicated, the percentage
relationship to net revenues of the Company's results of operations. This
information for quarterly periods has been prepared on the same basis as the
Consolidated Financial Statements and, in the opinion of the Company's
management, reflects all adjustments (consisting only of normal and recurring
adjustments and adjustments related to the Company's equity recapitalization)
necessary for the fair presentation of the information for the periods
presented.

</TABLE>
 
     In light of the Company's inception on February 26, 1997, the number of
acquisitions completed and the absence of significant operations through June
30, 1997, management has decided to present a comparison of results for the
three months ended June 30, 1998 versus the three months ended March 31, 1998
and for the three months ended March 31, 1998 versus the three months ended
December 31, 1997 because it believes that such comparisons are the most
meaningful presentation of the Company's operating results.
 
     All acquisitions completed by Nextera have been accounted for under the
purchase method of accounting. Accordingly, the historical Consolidated
Financial Statements of the Company included in the Prospectus include operating
results of the Acquired Companies only from the date of each respective
acquisition. As the Sibson Acquisitions were completed after June 30, 1998, the
following period-to-period comparisons do not reflect the Sibson Acquisitions.
 
COMPARISON OF THREE MONTHS ENDED JUNE 30, 1998 AND THREE MONTHS ENDED MARCH 31,
1998
 
     Net Revenues. Net revenues increased 69.9% to $13.9 million for the three
months ended June 30, 1998 from $8.2 million for the three months ended March
31, 1998. This increase was due predominately to the net revenues generated by
PTG and Pyramid, which were acquired effective March 31, 1998, and to a lesser
extent from higher utilization rates and greater business levels at Symmetrix.
No net revenues from PTG or Pyramid were recorded by Nextera in the three months
ended March 31, 1998.
 
     Gross Profit. Gross profit increased 79.2% to $4.6 million for the three
months ended June 30, 1998 from $2.6 million for the three months ended March
31, 1998. Gross margin increased to 33.0% for the three months ended June 30,
1998 from 31.3% for the three months ended March 31, 1998. The increase in gross
margin was due primarily to the addition of PTG and Pyramid and, to a lesser
extent, more effective utilization of consultants on billable projects and a
lower utilization of outside contractors, which decreased cost of revenues.
 
     Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased 52.0% to $4.4 million for the three months
ended June 30, 1998 from $2.9 million for the three months ended March 31, 1998.
As a percentage of net revenues, such expenses decreased to 31.7% for the three
months ended June 30, 1998 from 35.3% for the three months ended March 31, 1998.
The dollar increase was due primarily to the increase in the number of employees
attributable to the PTG and Pyramid acquisitions, as
 
                                       22
<PAGE>   24
 
well as additional hirings. The decrease as a percentage of net revenues was due
primarily to a greater increase in net revenues in relation to the increase in
such expenses.
 
     Interest Income (Expense), Net. Interest expense decreased 29.5% to $1.2
million for the three months ended June 30, 1998 from $1.6 million for the three
months ended March 31, 1998. This decrease was due primarily to the inclusion in
the three months ended March 31, 1998 of $0.8 million related to 1997 interest
on the Debentures, which was accrued in such period due to the recapitalization
of the Company. This decrease was partially offset by increased borrowings to
fund the PTG and Pyramid acquisitions. See "--Liquidity and Capital Resources,"
"Use of Proceeds" and Note 9 of Notes to the Company's Consolidated Financial
Statements.
 
     COMPARISON OF THREE MONTHS ENDED MARCH 31, 1998 AND THREE MONTHS ENDED
DECEMBER 31, 1997
 
     Net Revenues. Net revenues increased 65.1% to $8.2 million for the three
months ended March 31, 1998 from $5.0 million for the three months ended
December 31, 1997. This increase was due to the net revenues generated from
SiGMA, which was acquired under the purchase method of accounting on January 5,
1998, partially offset by reserves taken on a fixed fee contract which has now
been completed. No net revenues from SiGMA were recorded by Nextera for the
three months ended December 31, 1997.
 
     Gross Profit. Gross profit increased 22.5% to $2.6 million for the three
months ended March 31, 1998 from $2.1 million for the three months ended
December 31, 1997. Gross margin decreased to 31.3% for the three months ended
March 31, 1998 from 42.2% for the three months ended December 31, 1997. The
decrease in gross margin was due primarily to reserves taken on a fixed-fee
contract which has been completed, partially offset by the increased gross
profit generated from SiGMA.
 
     Selling, General and Administrative. Selling, general and administrative
expenses increased 16.8% to $2.9 million for the three months ended March 31,
1998 from $2.5 million for the three months ended December 31, 1997. As a
percentage of net revenues, such expenses decreased to 35.3% for the three
months ended March 31, 1998 from 49.8% for the three months ended December 31,
1997. The dollar increase was due primarily to the increase in the number of
employees attributable to the SiGMA acquisition as well as additional hirings.
The decrease as a percentage of net revenues was due primarily to a greater
increase in net revenues in relation to the increase in such expenses.
 
     Interest Income (Expense), Net. Net interest expense increased to $1.6
million for the three months ended March 31, 1998 from $43,000 for the three
months ended December 31, 1997. This increase was due primarily to interest on
the Debentures which was accrued in the three months ended March 31, 1998, $0.8
million of which related to contributions made in 1997. See "--Liquidity and
Capital Resources," "Use of Proceeds" and Note 9 of Notes to the Company's
Consolidated Financial Statements.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     To date, the Company has funded its operations primarily through the
proceeds of equity issuances and borrowings. Nextera LLC initially issued common
and preferred equity units between February 1997 and April 1998 for total
proceeds of approximately $50.0 million. On April 30, 1998, in connection with
the recapitalization of Nextera LLC, the preferred units and a portion of the
common units were converted into the Debentures. The Debentures accrue interest
at 10% per annum, and interest on the principal amount of the Debentures was
deemed to have begun to accrue on the date the respective equity capital
contributions were originally made. The total Debentures outstanding, including
accrued interest, at June 30, 1998 was $50.7 million. The Company intends to
repay the outstanding principal balance of the Debentures plus accrued interest
with a portion of the proceeds of the Offering. See "Use of Proceeds," "Certain
Transactions--Investments in the Company" and Note 12 of Notes to the Company's
Consolidated Financial Statements.
 
     As of June 30, 1998, the Company had utilized $41.1 million in connection
with acquisitions. Cash used by operations totaled $4.5 million and $0.1 million
for the period from February 26, 1997 (date of inception) through December 31,
1997 and the six months ended June 30, 1998, respectively.
 
                                       23
<PAGE>   25
 
     On August 31, 1998, the Company entered into the Bridge Loan. The Bridge
Loan is secured by substantially all of the Company's assets and contains
certain restrictive covenants. The Bridge Loan provides for financing in the
amount of $40.0 million, of which $38.0 million was used to finance the Sibson
Acquisitions. The Bridge Loan bears interest at the rate of LIBOR plus 450 basis
points (10.2% as of August 31, 1998) per annum and matures on February 28, 1999.
As of September 1, 1998, $38.0 million was outstanding under the Bridge Loan,
which will be repaid with a portion of the net proceeds of the Offering. See
"Use of Proceeds" and "Underwriting."
 
     Net cash used in operating activities was $0.1 million for the six months
ended June 30, 1998. The primary components of the net cash used in operations
were a net loss of $3.6 million, an increase in accounts and notes receivable of
$1.7 million, which were partially offset by depreciation and amortization of
$0.9 million, an increase in accounts payable and accrued liabilities of $1.7
million, and an increase in accrued interest related to the Debentures of $2.7
million.
 
     Net cash used in investing activities was $26.2 million for the six months
ended June 30, 1998. The primary components of the net cash used in investing
activities were (i) the acquisition of SiGMA in January 1998, the acquisition of
PTG effective in March 1998, and the acquisition of Pyramid effective in March
1998 totalling $25.8 million, exclusive of $1.5 million of cash acquired and
(ii) expenditures of $0.4 million for furniture, equipment and leasehold
improvements. See Note 1 of Notes to the Company's Consolidated Financial
Statements.
 
     Nextera, through the Acquired Companies, had an aggregate of $8.4 million
under credit facilities (collectively, the "Credit Facilities") as of August 31,
1998. Interest rates on the Credit Facilities are based on prime or commercial
paper interest rates plus margins varying from 0% to 3%. The Credit Facilities
are secured by substantially all of the assets of the applicable borrower.
Collectively, on a pro forma basis, $4.3 million was outstanding under the
Company's Credit Facilities at June 30, 1998 and bore interest at a weighted
average rate of 8.8%. Certain of the Credit Facilities contain restrictive
covenants relating to maintenance of financial ratios, operating restrictions,
and restrictions of the payment of dividends to Nextera. The Company intends to
consolidate these Credit Facilities in a new credit arrangement, however there
can be no assurances that such new credit arrangement will be obtained, and if
so, when and on what terms.
 
     The Company believes that the working capital generated from the net
proceeds from the Offering, together with available borrowings under the Credit
Facilities and cash flow expected to be generated from operations, will be
sufficient to finance the Company's currently anticipated capital requirements
for at least the next twelve months. There can be no assurance, however, that
the Company's actual needs will not exceed anticipated levels or that the
Company will generate sufficient net revenues to fund its operations in the
absence of other sources. There also can be no assurance that any additional
required financing will be available through additional bank borrowings, debt or
equity offerings or otherwise, or that if such financing is available, that it
will be available on terms favorable to the Company.
 
YEAR 2000 COMPLIANCE
 
     Many currently installed computer systems are coded to accept only two
digit entries in the date code field. These date code fields need to be modified
or upgraded to accept four digit entries to distinguish 21st century dates from
20th century dates. Nextera has completed an assessment of its computer systems
for Year 2000 compliance. Although the Company does not believe that the costs
of addressing Year 2000 compliance issues with respect to Nextera's own systems
will materially adversely affect its business, operating results or financial
condition, the Company depends on smooth and timely interactions with its
vendors, clients and other third parties. Any unexpected costs or disruption in
the operations or activities of such vendors, clients or other third parties as
a result of Year 2000 compliance issues within such entities could materially
adversely affect Nextera's business, operating results and financial condition.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
     During 1997, the Financial Accounting Standards Board issued Statement No.
130, Reporting Comprehensive Income ("Statement 130"). The Company will adopt
the provisions of Statement 130 during fiscal
 
                                       24
<PAGE>   26
 
year 1998. At that time, the Company will be required to disclose comprehensive
income. Comprehensive income is generally defined as all changes in members'
equity (deficit) exclusive of transactions with owners such as capital
investments and dividends.
 
     In June 1997, the Financial Accounting Standards Board issued Statement No.
131, Disclosures About Segments of an Enterprise and Related Information
("Statement 131"), which is required to be adopted for years beginning after
December 15, 1997. Management of the Company believes that they operate in only
one segment and accordingly does not expect the adoption of Statement 131 to
have a material impact on the Company's financial statement disclosures.

INDUSTRY BACKGROUND
 
     Change is one of the most important factors driving demand for professional
consulting services. Increased competition, deregulation, globalization,
technological advances, and evolving organizational models are leading to
changes in the business environment. Traditional barriers to competition are
becoming less effective in protecting competitive positions. Regulatory changes
have led to increased competition both from within industries and from new
entrants from other market sectors. Commercial activity is becoming increasingly
global, requiring consideration of both domestic and international operations in
strategic decision-making and resource utilization. With the advent of the
Internet and electronic commerce, technology is increasingly being used in a
variety of innovative, strategic ways to create new products and services, open
new sales and marketing channels, and reduce costs and time-to-market for
products and services. Moreover, business and IT strategies continue to converge
as organizations recognize that technology can create new business opportunities
as well as support existing business. In response to these challenges and
opportunities,
 
                                       26

organizations are altering traditional approaches to overall strategy, business
processes, organizational design, and the use of IT.
 
     Many organizations lack the skilled personnel, technical capabilities, and
time necessary to formulate strategies and implement changes needed to benefit
from these new challenges and opportunities. In addition, organizations must
continually keep pace with new technological and competitive developments, which
further strain internal resources. Moreover, organizations expect timely and
substantial economic returns from their investments in strategic initiatives and
organizational change. As a result, many organizations are increasingly
retaining third-party professionals for help and expertise.
 
     Demand for professional consulting services is expected to grow rapidly.
According to an industry source, the worldwide market for professional
consulting services is estimated at $46.3 billion in 1997, and is projected to
increase to $88.5 billion in 2002. It is estimated that the worldwide market for
strategy and business consulting services will grow at an annual rate of 12%,
from $19.9 billion in 1997 to $34.9 billion in 2002. The worldwide market for IT
consulting is estimated to grow at an annual rate of 14%, from $12.7 billion in
1997 to $24.8 billion in 2002. It is estimated that the worldwide market for
custom application development and integration will grow at an annual rate of
15%, from $13.7 billion in 1997 to $28.8 billion in 2002. Moreover, the Company
believes that the professional consulting services industry is highly fragmented
and will experience consolidation as service providers seek to expand and
enhance service to clients.
 
     Professional consulting services have traditionally been focused on issues
of business strategy, operations improvement, organizational design, and IT
consulting. Historically, consulting service providers have offered services
focusing on one or two of these issues and few providers have had the breadth of
expertise or balanced approach to providing services to address effectively
multi-disciplinary business problems. For example, service providers oriented
around strategy formulation and market assessment often provide some expertise
in addressing operational or organizational issues, but typically do not address
IT issues or opportunities.
 
     Given the rapidly changing nature of today's business environment,
traditional approaches do not provide the broad perspective or range of
expertise required for a comprehensive examination of the causes of business
problems. Consequently, consulting service providers employing traditional
approaches do not offer the types of balanced and integrated solutions critical
to solving the multi-disciplinary problems that organizations currently face. In
order to solve such problems, organizations are demanding that third-party
service providers have experience in a breadth of practice areas. For example,
organizations increasingly seek assistance not only to formulate strategy, but
also to implement strategic processes that support ongoing strategic decision-
making. As a result, organizations now demand highly-participative, fact-driven
strategic management processes that focus on strategic objectives and explicitly
link business processes, human capital, and IT strategies.
 
NEXTERA ADVANTAGE
 
     Through its portfolio of practice areas, Nextera offers a breadth and
balance of services that assist clients in achieving enhanced business
performance by anticipating and addressing their complex, multi-disciplinary
consulting needs. The Company helps organizations develop dynamic business
strategies and high performance business processes, and enhance organizational
effectiveness needed to achieve their visions and goals. The Company's flexible
delivery model, which combines expertise in business strategy, operations
improvement, organizational design, and IT consulting, along with its ability to
leverage its knowledge base, enables Nextera to solve its clients'
enterprise-wide management problems and deliver results which are timely and
cost-effective. The key elements of Nextera's advantage include:
 
     Portfolio of Complementary Practice Areas. Through its portfolio of four
practice areas--Business Research Services, Strategic Management Services, Human
Capital Services, and Business Performance Solutions--the Company addresses its
clients' needs from varying perspectives and draws on its experience from each
to provide multi-disciplinary services to its clients. Nextera utilizes this
balanced perspective to help clients identify and examine business problems and
to develop and implement the strategic, operational, and organizational
responses needed to solve such problems and sustain performance improvement. As
a result,
 
                                       27
<PAGE>   29
 
the Company, with its balanced perspective, offers objective and independent
services which are valued by organizations.
 
     Experience and Expertise. Nextera's experience within industries and
practice areas enables its consultants to more fully and rapidly understand
their clients' businesses and the competitive industry environments in which
they operate. The Company's senior consulting executives average more than 20
years of consulting or industry experience and have all held senior level
positions in large organizations with management responsibility for large
numbers of consultants. Of the Company's consultants, 54% have more than 10
years of consulting, technical or industry experience and 52% have either
doctorate or master's degrees.
 
     Long-term Client Relationships. The Company has established long-term
relationships with numerous clients, many of whom are Fortune 500 companies.
Through these relationships, the Company gains in-depth knowledge of its
clients' businesses and industries, which facilitates the Company's
identification of other complementary services and the ability to offer timely
services to these clients. As a result of these long-term relationships, the
Company has amassed significant expertise in a wide range of industries,
including the financial services, health care, utilities, and manufacturing
industries.
 
     Flexible Delivery Model. Nextera's flexible delivery model enables it to
provide timely and unbiased perspectives on client problems and implement
multi-disciplinary solutions. Initially, the Company is able to deliver services
in any of its practice areas and then expand the scope of its engagements to
include complementary or follow-on services in other practice areas. Nextera
delivers its services through Client Service Teams with the support of Affinity
Groups. For each engagement, Nextera establishes a Client Service Team managed
by a senior-level client service director and comprised of consultants who are
selected to provide the appropriate combination of industry experience,
functional expertise, and geographic coverage. Client service teams enhance
overall client satisfaction by enabling the senior-level client service director
to provide a single point of contact for the client and the overall team to take
a multi-disciplinary approach to engagements. Client Service Teams are supported
by Affinity Groups, which are comprised of individuals from across the Company's
practice areas as well as third-party practitioners. Affinity Group members draw
from their respective client work, industry experience, and expertise to share
knowledge and experiences and develop methodologies and tools used in the
delivery of services.
 
     Proprietary Information System and Scaleable Infrastructure. Nextera has
developed and is expanding its proprietary information system that facilitates
synergies across its practice areas and provides a scaleable infrastructure. The
foundation of the Company's IT infrastructure, Nextnet, provides the backbone
and architecture for a collection of integrated applications accessed through a
common, web-based user interface. Nextera's information system enables it to
share business information and knowledge among its consultants and to
effectively manage its corporate resources. Nextnet provides an interactive
environment through which defined groups, including Client Service Teams, can
collaborate to solve complex client problems. In addition to its information
system, Nextera's scaleable infrastructure incorporates recruiting, staff
development and deployment, collaborative marketing initiatives, sharing of
intellectual capital, and enterprise management systems.
 
     Nextera Culture. The Company emphasizes professionalism, independence, and
objectivity among its consultants, and believes that these attributes are
reflected in the quality of the services it provides to its clients. Nextera
encourages teamwork and knowledge sharing to foster the professional growth of
its consultants and enhance the delivery of services to clients. The Company
seeks to sustain high retention rates for consultants achieved by the Acquired
Companies by retaining certain key cultural elements of each Acquired Company.
Toward this end, Nextera's compensation and incentive programs are designed to
give all consultants the ability to become equity participants in the Company.
Stability among the Company's consultants leads to consistency in the
composition of Client Service Teams and a reduced learning curve on new projects
for existing clients.

GROWTH STRATEGY
 
     The Company's objective is to be a leading provider of consulting services
in its four practice areas. The key elements of the Company's growth strategy
include:
 
     Expand Service Offerings through Selective Acquisitions. Nextera intends to
continue to take advantage of the highly fragmented nature of the consulting
industry by acquiring select complementary consulting businesses. The Company is
developing its business around its practice areas and intends to broaden and
enhance its substantive expertise, service offerings, and geographic coverage
through strategic acquisitions. For example, to capitalize on the growth in
electronic commerce, the Company intends to evaluate potential acquisitions
designed to strengthen its capabilities in this area. From time to time, the
Company may also evaluate selective potential acquisitions outside these
practice areas if justified by client needs and market demand.
 
     Leverage Cross-selling Opportunities. Nextera intends to provide additional
services and expand the scope of engagements during delivery to include
follow-on complementary activities. The Company believes that its integrated
approach to its portfolio of practice areas and its ability to cross-sell will
significantly enhance its ability to establish, sustain, and expand
relationships with clients. The Company's close working relationship with its
clients affords it the opportunity to become aware of, and to help define,
additional project opportunities and to market additional capabilities to its
clients. Client service opportunities are disseminated and coordinated in
real-time through Nextera's Business Development System, a proprietary Nextnet
application providing company-wide access and the identification and sharing of
sales, marketing, and other business data.
 
     Attract and Retain Key Personnel. The Company intends to attract and retain
consultants who will enhance and complement the Company's service capabilities
by fostering a creative, innovative, collaborative work environment and through
competitive compensation and incentive programs. Nextera has a national
recruiting program aimed at hiring entry-level consultants as well as
consultants with experience at major management consulting firms, IT and process
consulting firms, technology companies, and from the industries that the Company
serves. Nextera's broad client base and flexible delivery model provide its
consultants diverse client experiences for professional growth. The Company
offers its consultants the opportunity to become equity participants in the
Company and has implemented policies and programs designed to accommodate
individual needs. For example, Nextera employs a "virtual office" concept to
provide travel and relocation flexibility where appropriate.
 
     Market the Nextera Brand Name. Nextera intends to continue to build a
common identity for the services it provides under the Nextera brand name. The
Company actively promotes its name and capabilities through its sales and
marketing activities. The Company believes that using a common brand name for
its services enhances its visibility and recognition in the market and improves
its ability to compete for new and expanded business. Nextera also believes that
its association with Knowledge Enterprises and Knowledge Universe will increase
the Company's market exposure and provide prospective client contacts and other
business opportunities.
 
     Expand International Presence. The Company intends to expand its
international presence through the growth of existing practices and selective
acquisitions of complementary consulting businesses in international markets.
The Company believes that clients will increasingly demand a global presence
from consulting service providers and Nextera intends to expand internationally
to participate in the market for global consulting services and to generate new
opportunities. Nextera's geographic priority is to expand its service offerings
in Europe within the Company's existing portfolio of practice areas.
 
SERVICE OFFERINGS
 
     The Company's portfolio of practice areas enables it to provide a breadth
and balance of services to its clients. By offering clients a combination of
business strategy, operations improvement, organizational design, and IT
consulting services, Nextera helps clients identify and examine business
problems and develop and implement the strategic, organizational, and
operational initiatives needed to solve such problems and sustain
 
                                       29
<PAGE>   31
 
performance improvement. Each of the Company's practice areas has a
well-articulated perspective that not only addresses its own particular service
offerings, but also promotes the logical flow of consulting services from
research to strategy to implementation and IT processes.
 
     For example, the Business Research Services practice area provides analyses
which often demonstrate the need for organizations to develop a business
strategy to proactively respond to new competitive challenges. The Strategic
Management Services practice area assists organizations in developing such
business strategy that can be interactively managed throughout the organization.
In order to successfully implement such business strategy, the Human Capital
Services practice area provides innovative services to address the need for
flexible and leverageable organizational structures. Finally, the Business
Performance Solutions practice area develops the creative business processes and
technology-enabled solutions that are designed to yield the desired results.
 
     The Company's four practice areas are as follows:
 
      Business Research Services. The Company provides in-depth and
forward-looking analyses of business challenges, relevant business frameworks,
and innovative business practices. This analysis and commentary gives clients an
early understanding of innovative yet practical ways to increase their
competitive strengths. Nextera combines the expertise of its consultants with
that of clients, third-party practitioners, and academics to provide focused
research on issues of client concern, including strategic management, product
development, demand chain management, supply chain management, customer
relationship management, human capital development, and knowledge management. To
date, the Company has published two research reports and commenced its first
multi-client study. Nextera intends to expand its research services to include
additional publications, multi-client studies, conferences, and electronic
information services.
 
      Strategic Management Services. The Company assists organizations in
developing, refining, and implementing successful business strategies. Nextera
works with the senior management of a client to develop multiple probable
scenarios based on external market conditions as well as current and potential
operational capabilities. Through the use of IT, the Company conducts analyses
of such information, assesses alternative strategies, and provides a basis for
consensus building. For example, a major regional bank, faced with significant
market discontinuity resulting from bank consolidations and the emergence of new
competitors, sought Nextera's assistance to determine strategies for future
growth. Through an analytically rigorous scenario planning process, the Company
helped its client decide to acquire a leading competitor and invest in emerging
business opportunities that could be critical to the client's future growth. As
a result of this new strategy, this client has strengthened its leading regional
market position.
 
      Human Capital Services. Nextera helps clients invest in and gain leverage
from their human capital by identifying the impact on their workforce of various
strategies. The Company also assists in developing new organizational designs by
establishing programs for personnel selection, recruitment, development, and
succession, identifying the drivers of business performance, and helping
organizations achieve critical focus from their workforce through programs to
enhance "business literacy." The Company also helps clients communicate and
implement organizational changes designed to respond to new opportunities or
competitive threats and establish reward programs for broad employee groups,
managers and executives. For example, when a leading defense contractor
transitioned its market focus from government clients to commercial clients, it
experienced uneven earnings across diversified business units. Nextera assisted
in establishing corporate and business unit goals focused on sustaining
profitable growth and enhancing shareholder value. In addition, the Company
helped design short- and long-term incentives for the client's senior managers
that were based on the expected contribution of their individual areas of
responsibility.
 
      Business Performance Solutions. Nextera helps organizations solve complex
operational issues through major business transformation programs, redesigned
business processes, best practices adaptation, and the use of emerging
technologies for high impact business process support systems and knowledge
management systems. The Company develops custom solutions that employ electronic
commerce and web-based technologies to redefine clients' processes for customer
service, new product development, and channel expansion. For example, Nextera
assisted a leading health care insurer in redesigning its process for developing
customized health care benefit plans in order to reduce operating costs while
maintaining or improving product quality and service delivery. As a result of
the Company's analysis, this client implemented Core Knowledge,
 
                                       30
<PAGE>   32
 
Nextera's proprietary automated system, to capture, organize, and process health
care information and provide a framework for the development of new health care
plans customized to meet the specifications of the client's customers. Core
Knowledge uses object-oriented technology to facilitate the creation and reuse
of modules which can be easily accessed and modified in the development and
deployment of new health care plans. The Company believes that these Core
Knowledge applications will enable the client to improve accuracy, enhance
product delivery, and significantly reduce costs.

</TABLE>
 
     Recent representative client engagements include the following:
 
     Strategic Management Services.  A major global insurance and financial
services company retained Nextera to develop a new corporate strategy for one of
its global businesses and to identify organizational and operational changes
needed to enable the client to pursue such new strategy. The Company's
consultants worked with the client's management team in a scenario based
planning process, which developed multiple probable future scenarios based on
external market factors as well as current and potential operational
capabilities, and then conducted simulations to test the effectiveness of
various strategies against each probable scenario. Using the results of these
simulations, the client's management team worked with Nextera to gain consensus
on their strategic direction. As a result of this process, the client decided to
pursue a strategy of focused growth and diversification, including selective
acquisitions. The client then worked closely with Nextera to conduct an
organizational alignment analysis, a highly structured process designed to
identify opportunities for work reduction and cost savings and to focus an
organization on the activities critical to providing the operational and
financial leverage necessary to execute the new strategy. The client has
estimated that the organizational alignment analysis identified annual cost
savings in excess of $100 million, which are expected to provide a financial
basis for the implementation of the client's new corporate strategy.
 
     Human Capital Services.  A leading consumer services company retained
Nextera to assist in addressing productivity and quality issues which the client
believed were hindering customer satisfaction and compressing margins.
Turn-around time demanded by customers had shortened and capital costs required
in this fast-
 
                                       32
<PAGE>   34
 
evolving business made cost management critical. Resulting downward pressure on
employee compensation was causing higher employee turnover and the client's
management team believed that its ability to hire better qualified employees was
being undermined by its compensation structure. Nextera studied quality and
productivity performance at 50 of the client's sites and identified the critical
points where the workforce had the most leverage over the process. Nextera then
helped the client develop employee incentive programs tailored to each
facility's process and geared toward the leverage points that could drive
productivity, quality, and cost performance in that facility. In addition,
Nextera developed a comprehensive communication program to introduce and
implement the new programs. The Company believes that the introduction of these
programs contributed to improved quality and productivity, decreased employee
turnover and absenteeism, and reduced overtime costs.
 
     Business Performance Solutions.  A subsidiary of a Fortune 500 company
retained Nextera to redesign its finance function by addressing issues of
organizational effectiveness and technology support. Working closely with the
client's financial management, the Company clarified the goals and role of the
finance function and analyzed the organizational factors and systems critical to
achieving such redesign. Nextera initiated a comprehensive solution that
modified the finance processes and standardized the client's general ledger and
financial reporting requirements. These initiatives were followed by the
Company's examination and conversion of the chart of accounts used by various
financial subsystems to conform to the new standardized accounting and reporting
requirements. Nextera also assisted the client in a broad variety of finance
initiatives, including process reengineering and redesign of its enterprise-wide
IT architecture. The Company believes that its services have enabled the client
to realize efficiencies in the finance function's information collection,
analysis and reporting activities.
 
FLEXIBLE DELIVERY MODEL
 
     Nextera's flexible delivery model provides clients with the full range of
the Company's expertise through a structured multi-disciplinary approach that
focuses on the needs and problems of each individual client. The Company's
breadth of expertise enables it to deliver services initially in any of its four
practice areas and expand the scope of its engagements to include complementary
or follow-on services in other practice areas. Nextera delivers its services
through Client Service Teams with the support of Affinity Groups. The key
elements of Nextera's flexible delivery model are as follows:
 
     Client Service Teams. For each engagement, Nextera establishes a Client
Service Team managed by a senior-level client service director and comprised of
consultants who are selected to provide the appropriate combination of industry
experience, functional expertise, and geographic coverage. Client service teams
enhance overall client satisfaction by enabling the senior-level client service
director to provide a single point of contact for the client and the overall
team to take a multi-disciplinary approach to engagements. In addition, Client
Service Teams increase visibility of potential opportunities and enhance the
Company's ability to establish strong relationships with the client's senior
executives. As a result, the Client Service Team develops an in-depth
understanding of the client's needs and focuses the Company's various service
capabilities to meet such needs, providing substantial value to the client.
Client Service Teams emphasize the Company's diverse capabilities to clients and
regularly cross-market across its practice areas.
 
     Affinity Groups. Client Service Teams are supported by Affinity Groups,
which are comprised of individuals from across the Company's practice areas and
third-party practitioners. Affinity Group members draw from their respective
client work, industry experience and expertise to share knowledge and best
practices and develop methodologies and tools used in the delivery of services
to clients and in the training of the Company's consultants. Affinity Groups
utilize Nextnet to facilitate the sharing of information and have formal and
informal meetings and discussions. The Company has established Affinity Groups
for the financial services, health care, and utilities industries and intends to
establish Affinity Groups for other key industry sectors and practice areas as
needed.

SALES AND MARKETING
 
     Nextera employs a variety of business development and marketing techniques
to reach prospective clients, including industry seminars featuring
presentations by Company personnel, trade press coverage, an Internet site, and
authoring of articles and other publications regarding market trends, emerging
business challenges and the Company's service offerings. Nextera's marketing
leadership team, with members from each of the Acquired Companies, sets the
Company's overall marketing priorities and provides oversight to key marketing
initiatives. The principal buyers of the Company's services are chief executive
officers and other senior executives with organizational policy-making
responsibilities.
 
     Nextera also relies to a significant extent on the efforts of its
employees, particularly its senior consulting executives and consultants, to
market the Company's services. Nextera employs a "selling practitioner" model in
which the Company's senior consulting executives are responsible for identifying
and obtaining new business as well as managing client engagements and
relationships. Consultants are encouraged to generate business from both
existing and new clients and successful efforts are rewarded with increased
compensation and promotions. Nextera's close working relationships with many of
its clients enable the Company's consultants to become aware of, and to help
define, additional project opportunities, thereby facilitating the Company's
ability to market additional capabilities to its clients. In pursuing new
business, the Company's consultants emphasize Nextera's overall capabilities and
experience while also promoting the expertise of the particular employees who
will work on the project. In addition, Nextera's senior consulting executives
meet with prospective clients and senior managers in organizations where Nextera
has worked in the past to make them aware of the Company's capabilities.
 
MANAGEMENT INFORMATION SYSTEM
 
     Nextera is investing in Nextnet to improve individual and organizational
performance through shared business information and knowledge. Nextnet provides
the backbone and architecture for a collection of integrated applications
accessed through a common web-based user interface. Nextnet facilitates rapid
delivery responsiveness by identifying the most qualified resources available
for each client engagement and encourages collaboration around resolution of
client problems, increasing quality, and expertise. The Company also utilizes
Nextnet to help integrate newly acquired companies into the Company's portfolio
of practice areas and rapidly adopt Nextera's business practices and procedures.
 
     The initial Nextnet application areas are the Nextera Business Development
System, the NextHR Employee Management System, and an integrated financial
system. The Business Development System, which is updated weekly by engagement
managers of each Acquired Company, provides company-wide management of all sales
leads and business opportunities and enhances Nextera's ability to set
priorities and manage future business. The first release of the NextHR Employee
Management System will provide skills and expertise location, staffing requests,
and job posting information. A company-wide, third-party financial management
system is being implemented and will be integrated with other Nextnet
applications.
 
     In addition to its application focus, Nextnet offers an interactive
environment through which user groups can share knowledge throughout the
Company. Using Nextnet, members of Client Service Teams and Affinity Groups
share timely information, tools, methodologies, and insights, which are
delivered to each consultant's personalized home page, creating a focused,
interactive environment.
 
     Nextnet has been developed to have a flexible and scaleable application
architecture. A high-performance SQL database drives the data elements of
Nextnet, while a full-text search engine enables knowledge management services.
Application logic is built using the latest web-development tools, and the
applications are delivered through an integrated browser interface.

HUMAN RESOURCES
 
     Nextera's ability to attract and retain experienced consultants to work on
client engagements and to generate new business is a key factor to Nextera's
success. As of August 31, 1998, the Company had 496 employees, including 355
consultants.
 
     Consulting Personnel. Nextera's senior consulting executives have an
average of 20 years of consulting or industry experience. Many of these senior
consulting executives are nationally recognized as experts in their respective
fields, having published articles and lectured extensively. Eight of the
Company's senior consulting executives have founded and managed successful
management and IT consulting firms. Of Nextera's consultants, 54% have more than
10 years of consulting, technical or industry experience and 52% have either
doctorate or master's degrees. This flexibility in staffing engagements enhances
Nextera's ability to apply its resources as needed to meet the demands of its
clients.
 
     Recruiting. Nextera seeks to hire consultants who not only have strong
analytical skills but also are creative, intellectually curious, and driven to
develop expertise in new practice areas and industries. The Company has a
national recruiting program aimed at hiring entry-level consultants as well as
consultants with experience at major management consulting, IT and process
consulting firms, technology companies, and from the industries that Nextera
serves. Entry-level consultants are recruited from leading graduate business
administration programs and undergraduate IT programs. In connection with its
hiring efforts, Nextera employs internal recruiters, retains several executive
search firms, and relies on personal and business contacts to recruit
experienced consultants.
 
     Compensation. In order to attract and retain consultants, Nextera offers
what it believes to be attractive compensation and benefits packages. Employee
compensation is a combination of base salary, bonus opportunity, and equity
participation. Consultant bonuses are paid out of bonus pools established for
each of the Acquired Companies through an annual operations planning process. A
consultant's bonus is based on the consultant's individual contributions and the
Acquired Company's performance. See "Management -- Bonus Plans."
 
     Training and Career Development. The Company has a career enhancement
program that offers its consultants career enrichment opportunities and access
to individualized training. Career development programs are specific to the
needs of each Acquired Company and all employees receive a combination of
orientation training, skills enhancement training, mentoring, and periodic
briefings. Nextera's flexible staffing methods are supported by its NextHR
Employee Management System to provide the Company's consultants with diverse and
challenging client experiences.
 
     Independent Contractors. When necessary, the Company supplements its
consultants on certain engagements with independent contractors. The Company
believes that its practice of retaining independent contractors on a
per-engagement basis provides it with greater flexibility in providing
specialized skills and adjusting consultant levels in response to changes in
demand for its services. Nextera's Business Research practice also employs
third-party practitioners and academics to conduct directed research on key
business performance topics.
 
COMPETITION
 
     The consulting services industry includes a large number of competitors, is
subject to rapid change, and is highly competitive. Nextera believes that the
principal competitive factors in the consulting services industry are
reputation, industry expertise, analytical ability, service, and price. The
Company believes it competes favorably with respect to these factors. Nextera
also believes that its ability to compete depends in part on a number of factors
outside of its control, including the ability of its competitors to hire, retain
and compensate consultants, offer lower-priced services, respond to client
requirements, and develop advanced services or technology. Nextera's primary
competitors include participants from a variety of market segments, including
general management consulting companies, boutique management consulting firms
that provide specialized services or focus on certain industries, "Big Five" and
other accounting firms, systems consulting and implementation firms, application
software firms, service groups of computer equipment companies, outsourcing
companies, and systems integration companies. Many of these competitors have
significantly greater
 
                                       35
<PAGE>   37
 
financial, technical, and marketing resources, and greater name recognition than
Nextera. In addition, many of these competitors have been operating for a
significantly longer period of time than the Company and have established
long-term client relationships. Nextera also competes with its clients' internal
resources, particularly where the resources represent a fixed cost to the
client. Such competition may impose additional pricing pressures on Nextera. In
addition, Nextera faces intense competition in its efforts to recruit and retain
qualified consultants. There can be no assurance that the Company will be able
to compete successfully with its existing competitors or any new competitors.
 
INTELLECTUAL PROPERTY RIGHTS
 
     The Company's success has resulted, in part, from its analytical templates,
application frameworks, software objects and customizable applications. Nextera
relies upon a combination of nondisclosure, confidentiality, license and other
contractual arrangements and trade secret, copyright and trademark laws to
protect its proprietary rights and the proprietary rights of third parties from
whom the Company licenses intellectual property. In addition, Nextera generally
limits the distribution of its proprietary information. There can be no
assurance, however, that the steps taken by Nextera to protect its intellectual
property will be adequate to deter misappropriation of proprietary information
or that the Company will be able to detect unauthorized use and take appropriate
steps to enforce its intellectual property rights or that competitors will not
be able to develop similar or functionally equivalent methodologies.
Furthermore, effective copyright and trade secret protection may be unavailable
or limited in certain foreign countries, and no assurance can be given that
foreign copyright and trade secret laws will adequately protect the Company's
intellectual property rights. Although Nextera believes that its services do not
infringe on the intellectual property rights of others and that it has all
rights necessary to utilize the intellectual property employed in its business,
there can be no assurance that Nextera's employees will not misappropriate the
intellectual property of others. Accordingly, the Company is subject to the risk
of claims alleging infringement of third-party intellectual property rights. Any
such claims could require the Company to spend significant sums in litigation,
pay damages, develop non-infringing intellectual property or acquire licenses to
the intellectual property that is the subject of asserted infringement. The
Company presently holds no patents or registered copyrights.
 
FACILITIES
 
     The Company's corporate headquarters is located in Lexington, Massachusetts
in a leased facility consisting of approximately 6,900 square feet, under a
four-year lease that expires in 2002. The Company also occupies leased office
space in Los Angeles, California; San Francisco, California; Chicago, Illinois;
Boston, Massachusetts; Lexington, Massachusetts; Princeton, New Jersey; New
York, New York; Rochester, New York; Raleigh, North Carolina; Toronto, Canada;
and London, England. The Company believes that its existing facilities are
adequate to meet its current requirements and that suitable space will be
available as needed on terms acceptable to the Company.
 
LEGAL PROCEEDINGS
 
     From time to time the Company is involved in legal proceedings, claims and
litigation arising in the ordinary course of business, the outcome of which, in
the opinion of management, would not have a material adverse effect on the
Company.

BOARD OF DIRECTORS
 
     The Company's Certificate of Incorporation and its Bylaws provide that the
Company's Board of Directors will consist of not less than seven nor more than
thirteen members, the exact number to be fixed from time to time by resolution
adopted by the directors of the Company. The Board of Directors currently
consists of seven directors. Directors will be elected by the holders of Class A
Common Stock and Class B Common Stock voting together as a class with the
holders of Class A Common Stock entitled to one vote per share and the holders
of the Class B Common Stock entitled to ten votes per share. See "Risk Factors--

Company prior to the Offering (including Knowledge Enterprises) agreed to vote

Audit Committee makes recommendations concerning the engagement of independent
public accountants, reviews with the independent public accountants the plans

compensation committee (the "Compensation Committee"), currently consisting of

BONUS PLANS
 
     As a key component of the annual compensation program, the Company has
implemented a bonus plan designed to recognize individual and Acquired Company
performance. The bonus plan is funded by the performance of each Acquired
Company (other than Sibson) and is intended to complement base compensation
while providing incentive and recognition for exceptional individual and team
efforts in meeting and exceeding such Acquired Company's operating targets. All
employees with three months or more of service are eligible to participate.
Employee target bonus percentages range from 10% to 50% of the individual's base
salary, dependent on their classification. Bonus calculations are dependent upon
an employee's target bonus percentage, individual performance rating, annualized
service as well as the final performance of the applicable Acquired Company.
 
     Sibson & Company, LLC, a subsidiary of the Company ("Sibson LLC") has
established an Annual Incentive Plan, the principal purpose of which is to
attract and motivate the principals and certain employees of Sibson LLC by
providing them with the opportunity to participate in Sibson LLC's success.
Bonus awards under the plan are distributed semi-annually to the participants
from an award pool based upon the performance of the individual participant and
Sibson LLC during such six-month period and the target bonus award for the
participant as established by Sibson LLC management. This plan provides for an
annual award pool based on Sibson LLC's financial performance and is
administered by Sibson LLC management, subject to the Company's approval with
respect to the establishment of performance criteria for the individual
participants and Sibson LLC.

(1) The potential realizable values are based on an assumption that the stock
    price of the Company's Class A Common Stock will appreciate at the annual
    rate shown (compounded annually) from the date of grant until the end of the
    option term. The Board of Directors has determined that the fair market
    value of the Company's Class A Common Stock on the date of grant was $0.20
    per share. These values do not take into account amounts required to be paid
    as income taxes under the Internal Revenue Code and any applicable state
    laws or option provisions providing for termination of an option following
    termination of employment, non-transferability or vesting. These amounts are
    calculated based on the requirements promulgated by the Commission and do
    not reflect the Company's estimate of future stock price growth of the
    shares of the Class A Common Stock, nor do they give effect to any actual
    appreciation in the Class A Common Stock. Actual gains, if any, on stock
    option exercises are dependent on the future performance of the Class A
    Common Stock and overall stock market conditions.

(1) Options are in-the-money if the market value of the shares covered thereby
    is greater than the option exercise price. This calculation is based on the
    fair market value at December 31, 1997 of $0.25 as determined by the Board
    of Directors.

EMPLOYEE BENEFIT PLANS
 
     1998 Equity Participation Plan. Nextera's 1998 Equity Participation Plan
provides incentives for officers, key employees and consultants of the Company
and its subsidiaries through granting of options, restricted stock and other
awards ("Awards"). In addition to Awards made to officers, key employees or
consultants, the 1998 Equity Participation Plan permits the granting of options
("Director Options") to the Company's independent non-employee directors.
 
                                       43
<PAGE>   45
 
     Under the 1998 Equity Participation Plan, not more than
shares of Class A Common Stock (or the equivalent in other equity securities)
are authorized for issuance upon exercise of options, stock appreciation rights
("SARs"), and other Awards, or upon vesting of restricted or deferred stock
awards. The maximum number of shares which may be subject to options or stock
appreciation rights granted under the 1998 Equity Participation Plan to any
individual in any calendar year cannot exceed                . As of September
1, 1998, options to purchase           shares of Class A Common Stock were
outstanding under the 1998 Equity Participation Plan.
 
     Prior to the closing of the Offering, the Board of Directors of the Company
will administer the 1998 Equity Participation Plan. After the closing of the
Offering, the Compensation Committee of the Board or another committee thereof
(the "Committee") will administer the 1998 Equity Participation Plan with
respect to grants to key employees or consultants of the Company and the full
Board of Directors will administer the 1998 Equity Participation Plan with
respect to Director Options. The Committee will consist of at least two members
of the Board of Directors, each of whom is a "non-employee director" for
purposes of Rule 16b-3 under the Securities Exchange Act of 1934, as amended
("Rule 16b-3") and, with respect to options and SARs which are intended to
constitute performance-based compensation under Section 162(m) of the Internal
Revenue Code of 1986, as amended (the "Code"), an "outside director" for the
purposes of Section 162(m) of the Code. Subject to the terms and conditions of
the 1998 Equity Participation Plan, the Board of Directors or Committee has the
authority to select the persons to whom Awards are to be made, to determine the
number of shares to be subject thereto and the terms and conditions thereof, and
to make all other determinations and to take all other actions necessary or
advisable for the administration of the 1998 Equity Participation Plan. The
Board of Directors or Committee may delegate to certain officers of the Company
its authority to select the persons to whom Awards are to be made, to determine
the number of shares to be subject thereto and the terms and conditions thereof.
In addition, the Board of Directors has discretion to determine the terms and
conditions of Director Options and to interpret and administer the 1998 Equity
Participation Plan with respect to Director Options. The Committee (and the
Board of Directors) are also authorized to adopt, amend and rescind rules
relating to the administration of the 1998 Equity Participation Plan.
 
     Options, SARs, restricted stock and other Awards under the 1998 Equity
Participation Plan may be granted to individuals who are then officers or other
key employees of the Company or any of its present or future subsidiaries. Such
Awards also may be granted to consultants of the Company selected by the Board
of Directors or Committee for participation in the 1998 Equity Participation
Plan. Non-employee directors of the Company may be granted NQSOs (as defined
herein) by the Board of Directors. The Committee may grant or issue stock
options, SARs, restricted stock, deferred stock, dividend equivalents,
performance awards, stock payments and other stock related benefits, or any
combination thereof to key employees and consultants. Each Award will be set
forth in a separate agreement with the person receiving the Award and will
indicate the type, terms and conditions of the Award.
 
     Nonqualified Stock Options ("NQSOs") will provide for the right to purchase
Class A Common Stock at a specified price which, except with respect to NQSOs
intended to qualify as performance-based compensation under Section 162(m) of
the Code, may be less than fair market value on the date of grant (but not less
than par value), and usually will become exercisable (in the discretion of the
Board of Directors) in one or more installments after the grant date, subject to
the participant's continued employment with the Company and/or subject to the
satisfaction of individual or Company performance targets established by the
Board of Directors and/or the Company. NQSOs may be granted for a term of up to
ten (10) years, as specified by the Board of Directors.
 
     Incentive Stock Options ("ISOs"), will be designed to comply with the
provisions of the Code and will be subject to certain restrictions contained in
the Code. Among such restrictions, ISOs must have an exercise price not less
than the fair market value of a share of Class A Common Stock on the date of
grant, may only be granted to key employees, must expire within a specified
period of time following the Optionee's termination of employment, and must be
exercised within the ten years after the date of grant; but may be subsequently
modified to disqualify them from treatment as ISOs. In the case of an ISO
granted to an individual who owns (or is deemed to own) at least 10% of the
total combined voting power of all classes of
 
                                       44
<PAGE>   46
 
stock of the Company, the 1998 Equity Participation Plan provides that the
exercise price must be at least 110% of the fair market value of a share of
Class A Common Stock on the date of grant and the ISO must expire upon the fifth
anniversary of the date of its grant.
 
     Restricted Stock may be sold to any key employee or consultant at various
prices (but not below par value) and made subject to such restrictions as may be
determined by the Committee. Restricted stock, typically, may be repurchased by
the Company at the original purchase price if the conditions or restrictions are
not met. In general, restricted stock may not be sold, or otherwise transferred
or hypothecated, until restrictions are removed or expire. Purchasers of
restricted stock, unlike recipients of options, will have voting rights and will
receive dividends prior to the time when the restrictions lapse.
 
     Deferred Stock may be awarded to any key employee or consultant, typically
without payment of consideration, but subject to vesting conditions based on
continued employment or on performance criteria established by the Committee.
Like restricted stock, deferred stock may not be sold, or otherwise transferred
or hypothecated, until vesting conditions are removed or expire. Unlike
restricted stock, deferred stock will not be issued until the deferred stock
award has vested, and recipients of deferred stock generally will have no voting
or dividend rights prior to the time when vesting conditions are satisfied.
 
     SARs may be granted to any key employee or consultant in connection with
stock options or other Awards, or separately. SARs granted by the Committee in
connection with stock options or other Awards will provide for payments to the
holder based upon increases in the price of the Company's Class A Common Stock
over the exercise price of the related option or other Awards. Except as
required by Section 162(m) of the Code with respect to an SAR intended to
qualify as performance-based compensation as described in Section 162(m) of the
Code, there are no restrictions specified in the 1998 Equity Participation Plan
on the exercise of SARs or the amount of gain realizable therefrom, although
restrictions may be imposed by the Board of Directors or Committee in the SAR
agreements. The Committee may elect to pay SARs in cash or in Class A Common
Stock or in a combination of both.
 
     Dividend Equivalents may be granted to any key employee or consultant by
the Board of Directors or the Committee. The amount of the Dividend Equivalents
represent the value of the dividends per share paid by the Company, calculated
with reference to the number of shares covered by the stock options, Deferred
Stock, Performance Awards, SARs or other Awards held by the participant.
 
     Performance Awards may be granted to any key employee or consultant by the
Committee. Generally, these Awards will be based upon specific performance
targets and may be paid in cash or in Class A Common Stock or in a combination
of both. Performance Awards may also include bonuses which may be granted by the
Committee which may be payable in cash or in Class A Common Stock or in a
combination of both.
 
     Stock Payments may be received by any key employee or consultant selected
by the Committee in the manner determined from time to time by the Committee.
The number of shares of Class A Common Stock or an option or other right to
purchase Class A Common Stock shall be determined by the Committee, and may be
based upon performance criteria as determined by the Committee.
 
     The 1998 Equity Participation Plan prohibits any participant in the plan
from, without the prior written consent of the representatives of the
Underwriters and subject to certain exceptions, selling or otherwise disposing
of any shares of Class A Common Stock or options to acquire shares of Class A
Common Stock during the 180-day period following the date of this Prospectus.
 
     Retirement Plans. Nextera and certain subsidiaries sponsor retirement
savings plans (the "Retirement Plans") under Section 401(k) of the Code for the
benefit of employees meeting certain minimum service requirements. Eligible
employees may elect to contribute to the plan subject to limitations established
by the Code. The trustees of the Retirement Plans select investment
opportunities from which participants may choose to contribute. The Company
matches up to 25% of the first 4% of eligible participant contributions for
employees of PTG, Pyramid, SiGMA and the Company's Executive Officers and
administrative personnel. The Company has agreed to match 25% of total
contributions (subject to the limitations of the Code) for individuals who are
active employees of Symmetrix as of December 31, 1998. Other contributions are
made at
 
                                       45
<PAGE>   47
 
the discretion of the Company. On a pro forma basis, the Company made
contributions to the Retirement Plans of $139,000 for the year ended December
31, 1997.
 
     Sibson LLC maintains a defined contribution profit-sharing plan (the
"Profit-Sharing Plan") providing retirement benefits to eligible employees of
Sibson LLC. Contributions by the Company to the Profit-Sharing Plan are at the
discretion of the management of Sibson LLC, subject to overall budgetary control
by Nextera. Participants are eligible to make elective deferral contributions,
without matching by Sibson LLC. Sibson LLC may also make qualified non-elective
contributions. For the year ended December 31, 1997 on a pro forma basis, Sibson
LLC contributed $1.5 million to the Profit-Sharing Plan. Sibson LLC intends to
make additional contributions to the Profit-Sharing Plan in the future as
determined by Sibson management.
 
     Other. The Company maintains customary health and benefit plans for its
employees. In addition, Sibson LLC currently provides post-retirement medical
benefits for Sibson LLC employees who retire after age 50 with at least 15 years
of service. Any such Sibson retiree may elect to receive medical coverage under
Sibson LLC's medical program until the earlier of age 65 or the retiree's death.
Sibson LLC pays 75% of the annual cost of the comprehensive medical coverage and
the retiree pays the remaining 25%. In connection with the Sibson Acquisitions,
the Company committed to maintain this post-retirement medical coverage (and all
other Sibson employee benefit programs) through December 31, 1999, subject to
certain limited exceptions, and the termination of applicable employment
agreements.

                              CERTAIN TRANSACTIONS
 
     Loans to Certain Officers. NEH made loans to Gresham T. Brebach, Jr., the
Company's Chief Executive Officer, Michael P. Muldowney, the Company's Chief
Financial Officer and Debra I. Bergevine, the Company's Vice President,
Marketing, the proceeds of which were used to purchase from NEH Preferred Units
of NEH. These loans were evidenced by promissory notes, dated January 2, 1998,
executed by the respective individuals in favor of NEH, and secured by a
security interest in the respective membership units purchased by these
individuals. All of the foregoing promissory notes bear interest at 10% per
annum and mature on January 2, 2003, subject to mandatory prepayment upon the
happening of certain events. The principal amounts of the promissory notes
executed by Messrs. Brebach and Muldowney and Ms. Bergevine are $576,000,
$72,000 and $62,000, respectively. All of the foregoing promissory notes and
security documents were contributed to, and are now held by, the Company. The
foregoing Preferred Units purchased by Messrs. Brebach and Muldowney and Ms.
Bergevine were ultimately converted to a 1.2%, 0.1% and 0.1% interest,
respectively, in the Debentures.
 
     Management Agreement. Effective March 1, 1997, Nextera entered into an oral
agreement with Knowledge Universe whereby Knowledge Universe provided certain

    Securities and Exchange Commission and includes voting or investment power
    with respect to securities. Shares of Common Stock issuable upon the
    exercise of stock options exercisable within 60 days hereof are deemed
    outstanding and to be beneficially owned by the person holding such option
    for purposes of computing such person's percentage ownership, but are not
    deemed outstanding for the purposes of computing the percentage ownership of
    any other person. Except for shares held jointly with a person's spouse or
    subject to applicable community property laws, or as indicated in the
    footnotes to this table, each stockholder identified in the table possesses
    the sole voting and disposition power with respect to all shares of Common

    Milken may each be deemed to have the power to direct the voting and
    disposition of, and to share beneficial ownership of, any shares of Common
    Stock owned by Knowledge Enterprises. The Company believes that Lawrence J.

                          DESCRIPTION OF CAPITAL STOCK
 
     Upon the consummation of the Offering, the authorized capital stock of the
Company will consist of 50,000,000 shares of Class A Common Stock, par value
$0.001 per share, 4,300,000 shares of Class B Common Stock, par value $0.001 per
share, and 10,000,000 shares of Preferred Stock, par value $0.001 per share. As
of September 1, 1998, there were        shares of Class A Common Stock issued
and outstanding (including the Exchangeable Shares) which were held by 45
shareholders (including the holders of Exchangeable Shares),        of Class B
Common Stock issued and outstanding which were held by 18 shareholders and no
shares of Preferred Stock issued and outstanding. In addition, there were 470
holders of options to acquire an aggregate of           shares of Class A Common
Stock. All outstanding shares of Common Stock are, and the shares of Class A
Common Stock offered hereby will be, upon payment therefor, fully paid and
nonassessable.
 
COMMON STOCK
 
     Voting Rights. The Class A Common Stock entitles its holders to one vote
per share and the Class B Common Stock entitles its holders to ten votes per
share on all matters submitted to a vote of the Company's stockholders,
including in connection with the election of the Board of Directors. Holders of
Class A Common Stock and Class B Common Stock vote together as a single class on
all matters presented to the stockholders for their vote or approval, except as
may be required by Delaware law or as otherwise expressly specified in the
Certificate of Incorporation. The Company, by action of its Board of Directors
and the affirmative vote of the holders of a majority of the voting power of the
Class A Common Stock and Class B Common Stock, voting together as a class, may
increase or decrease the number of authorized shares of Class A Common Stock or
Preferred Stock. The Company, by action of its Board of Directors and the
affirmative vote of both (i) the holders of a majority of the voting power of
the Class A Common Stock and Class B Common Stock, voting together as a class,
and (ii) the holders of a majority of the voting power of the Class B Common
Stock, voting as a separate class, may increase or decrease the number of
authorized shares of Class B Common Stock.
 
     Dividends. Holders of Class A Common Stock and Class B Common Stock are
entitled to receive dividends at the same rate, when and if declared by the
Board of Directors, out of legally available funds. The Company may not make any
dividend or distribution with respect to any class of Common Stock unless at the
same time the Company makes a ratable dividend or distribution with respect to
each outstanding share of Common Stock regardless of class. In the case of a
stock dividend or other distribution payable in shares of a class of Common
Stock, only shares of Class A Common Stock may be distributed with respect to
Class A Common Stock and only shares of Class B Common Stock may be distributed
with respect to Class B Common Stock, and the number of shares of Common Stock
payable per share will be equal for each class.
 
     Split, Subdivision or Combination. None of the Class A Common Stock or the
Class B Common Stock may be subdivided, consolidated, reclassified or otherwise
changed in any manner unless the other class is subdivided, consolidated,
reclassified or otherwise changed in the same proportion.
 
     Conversion Rights. The Class A Common Stock has no conversion rights. Each
share of Class B Common Stock is convertible at any time, at the option of the
holder, into one share of Class A Common Stock. Each share of Class B Common
Stock shall convert automatically into one share of Class A Common Stock upon
its sale, assignment, pledge, gift or other transfer (an "Assignment" or to
"Assign"), other than (a) to a Controlled Affiliate of the transferor; or (b)
pursuant to a Qualified Transfer (as defined below). The term "Controlled
Affiliate" means, with respect to a transferor, any individual or entity that is
controlled directly or indirectly (by ownership of voting securities, contract
or otherwise) by such transferor. "Qualified Transfer" means (i) any transfer of
shares of Class B Common Stock by will or pursuant to the laws of descent and
distribution to any member or members of a stockholder's Family, (ii) any
transfer of shares of Class B Common Stock by a stockholder to a domestic trust
created for the sole benefit of one or more of the stockholder or any member or
members of the stockholder's Family, (iii) any transfer of shares of Class B
Common Stock from a trust described in clause (ii) above to the stockholder (or
former stockholder) who transferred shares of Class B Common Stock to such
trust, (iv) any transfer to a domestic limited partnership or a domestic limited
liability company if there are no partners or members of such limited
partnership or
 
                                       52
<PAGE>   54
 
limited liability company other than a stockholder and members of a
stockholder's Family; (v) any transfer of Class B Common Stock from a limited
partnership or limited liability company described in clause (iv) above to a
stockholder (or former stockholder) who transferred Class B Common Stock to such
limited partnership or limited liability company; and (vi) any transfer of
shares of Class B Common Stock from one holder of Class B Common Stock to
another holder of Class B Common Stock as of August 31, 1998. "Family" means a
person's spouse, lineal descendants, parents, siblings, and lineal descendants
of siblings. Any such relationship by legal adoption shall be included.
 
     Upon any Assignment of Class B Common Stock by Knowledge Enterprises, other
than to a Controlled Affiliate or pursuant to a Qualified Transfer, a
proportionate amount of the Class B Common Stock held by the other holders of
Class B Common Stock will also automatically convert into Class A Common Stock.
For example, if Knowledge Enterprises Assigns 25% of its Class B Common Stock to
a third party who is not an Affiliate and not pursuant to a Qualified Transfer,
then those shares of Class B Common Stock will automatically convert into Class
A Common Stock on a one-to-one basis and 25% of the Class B Common Stock held by
each other holder of Class B Common Stock will automatically convert into Class
A Common Stock on a one-to-one basis.
 
     In the event that a group comprised of one or more of Michael R. Milken,
Lawrence J. Ellison or Lowell J. Milken cease to control, directly or indirectly
(through the ownership of voting securities, contract or otherwise), Knowledge
Enterprises or any other person or entity that owns any or all of the shares of
Class B Common Stock owned by Knowledge Enterprises on the date hereof, then all
shares of Class B Common Stock shall automatically convert into shares of Class
A Common Stock.
 
     Notwithstanding the foregoing, (i) these automatic conversion provisions
shall not apply in the case of a merger or similar transaction by the Company in
which all the outstanding shares of Common Stock of the Company regardless of
class are purchased by the acquiror, and (ii) any holder of Class B Common Stock
may pledge his shares of Class B Common Stock to a financial institution (the
"Pledgee") pursuant to a bona fide pledge of such shares as collateral security
for indebtedness due to the Pledgee, and, if the Pledgee forecloses or takes
similar action, such pledged shares of Class B Common Stock shall be converted
automatically into shares of Class A Common Stock.
 
     Merger. Upon the merger or consolidation of the Company, holders of each
class of Common Stock will be entitled to receive equal per share payments or
distributions, except that in any transaction in which shares of capital stock
are distributed, such shares may differ only to the extent that the Class A
Common Stock and the Class B Common Stock differ as provided in the Company's
Certificate of Incorporation.
 
     Liquidation Rights. Upon any dissolution or liquidation of the Company, the
holders of the Class A Common Stock and Class B Common Stock will be entitled to
receive ratably all assets of the Company available for distribution to
stockholders, subject to any preferential rights of any then outstanding shares
of Preferred Stock.
 
     Other Provisions. The holders of the Class A Common Stock and Class B
Common Stock are not entitled to preemptive rights. The rights of holders of
Class A Common Stock and Class B Common Stock are subject to the rights of
holders of shares of any series of Preferred Stock that the Company may
designate and issue in the future.
 
     The Certificate of Incorporation provides that each holder of shares of
Common Stock, other than shares of Common Stock acquired in the Offering,
agrees, subject to certain exceptions, not to (i) offer, pledge, sell, contract
to sell, sell any option or contract to purchase, purchase any option or
contract to sell, grant any option, right or warrant to purchase or otherwise
transfer or dispose of, directly or indirectly, any shares of Common Stock or
any securities convertible into or exercisable or exchangeable for Common Stock
or (ii) enter into any swap or other arrangement that transfers all or a portion
of the economic consequences associated with the ownership of any Common Stock
(regardless of whether any of the transactions described in clause (i) or (ii)
is to be settled by the delivery of Common Stock, or such other securities, in
cash or otherwise) for a period of 180 days after the date of this Prospectus
without the prior written consent of DLJ. In addition, during such period, each
holder of shares of Common Stock, other than shares of Common Stock
 
                                       53
<PAGE>   55
 
acquired in the Offering, agrees, subject to certain exceptions, not to make any
demand for, or exercise any right with respect to, the registration of any
shares of Common Stock or any securities convertible into or exercisable or
exchangeable for Common Stock without DLJ's prior written consent.
 
PREFERRED STOCK
 
     The Company's Certificate of Incorporation allows the Company to issue
without stockholder approval Preferred Stock having rights senior to those of
the Common Stock. As of the date of this Prospectus, no shares of Preferred
Stock will be outstanding. Therefore, the Board of Directors has the authority,
without further action by the stockholders, to issue up to 10,000,000 shares of
Preferred Stock from time to time in one or more series. Each series of
Preferred Stock will have the number of shares, designations, powers,
preferences, and special or relative rights and privileges as may be determined
by the Board of Directors, which may include dividend rights, voting rights,
redemption and sinking fund provisions, liquidation preferences, and conversion
rights. The authority of the Board of Directors to issue Preferred Stock without
further action by the stockholders provides flexibility in connection with
possible acquisitions and other corporate purposes, but may also result in the
issuance of Preferred Stock with voting, conversion or other rights that could
adversely affect the voting power and other rights of the holders of Common
Stock.
 
     The issuance of Preferred Stock may have the effect of delaying or
preventing a change in control of the Company. The issuance of Preferred Stock
could decrease the amount of earnings and assets available for distribution to
the holders of Common Stock and in some circumstances have the effect of
decreasing the market price of the Common Stock. The Company currently has no
plans to issue any shares of Preferred Stock.
 
EXCHANGEABLE SHARES
 
     In connection with the Sibson Acquisitions, Nextera LLC formed Sibson
Acquisition Co., a wholly owned Canadian subsidiary, which issued Exchangeable
Shares to the holders of capital stock of Sibson Canada, Inc. The holders of
Exchangeable Shares may exchange such shares at any time for an aggregate of
          shares of Class A Common Stock. The Exchangeable Shares are designed
to provide an opportunity for the shareholders of Sibson Canada, Inc. to achieve
a Canadian tax deferral in certain circumstances. The holders of Exchangeable
Shares are entitled to dividend and other rights equivalent to shares of Class A
Common Stock but are not entitled to vote on matters submitted to the holders of
Class A Common Stock until such time as the holders of Exchangeable Shares
exchange such shares for Class A Common Stock.
 
CERTAIN PROVISIONS OF DELAWARE LAW AND THE COMPANY'S CERTIFICATE INCORPORATION
 
     The following is a description of certain provisions of the Delaware
General Corporation Law (the "DGCL") and the Company's Certificate of
Incorporation and Bylaws. This summary does not purport to be complete and is
qualified in its entirety by reference to the DGCL, the Certificate of
Incorporation and the Bylaws.
 
     Certain provisions of the Certificate of Incorporation and the Bylaws could
have anti-takeover effects. These provisions are intended to enhance the
likelihood of continuity and stability in the composition of the policies
formulated by the Board of Directors. In addition, these provisions are intended
to ensure that the Board will have sufficient time to act in what the Board of
Directors believes to be the best interests of the Company and its stockholders.
These provisions also are designed to reduce the vulnerability of the Company to
an unsolicited proposal for a takeover of the Company that does not contemplate
the acquisition of all of its outstanding shares or an unsolicited proposal for
the restructuring or sale of all or part of the Company. The provisions are also
intended to discourage certain tactics that may be used in proxy fights.
 
     Delaware Anti-Takeover Law. The Company is a Delaware corporation that is
subject to Section 203 of the DGCL. Under Section 203, certain "business
combinations" between a Delaware corporation whose stock generally is publicly
traded or held of record by more than 2,000 stockholders and an "interested
stockholder" are prohibited for a three-year period following the date that such
stockholder became an interested stockholder, unless (i) the corporation has
elected in its Certificate of Incorporation or Bylaws not to be
 
                                       54
<PAGE>   56
 
governed by Section 203 (the Company has not made such an election), (ii) the
business combination or the transaction which resulted in the stockholder
becoming an interested stockholder was approved by the board of directors of the
corporation before such stockholder became an interested stockholder, (iii) upon
consummation of the transaction that made such stockholder an interested
stockholder, the interested stockholder owned at least 85% of the voting stock
of the corporation outstanding at the commencement of the transaction (excluding
voting stock owned by directors who are also officers or held in employee
benefit plans in which the employees do not have a confidential right to tender
stock held by the plan in a tender or exchange offer) or (iv) the business
combination is approved by the board of directors of the corporation and
authorized at a meeting by two-thirds of the voting stock which the interested
stockholder does not own. The three-year prohibition also does not apply to
certain business combinations proposed by an interested stockholder following
the announcement or notification of certain extraordinary transactions involving
the corporation and a person who had not been an interested stockholder during
the previous three years or who became an interested stockholder with the
approval of a majority of the corporation's directors. The term "business
combination" is defined generally to include mergers or consolidations between a
Delaware corporation and an interested stockholder, transactions with an
interested stockholder involving the assets or stock of the corporation or its
majority-owned subsidiaries, and transactions which increase an interested
stockholder's percentage ownership of stock. The term "interested stockholder"
is defined generally as (i) those stockholders who become beneficial owners of
15% or more of a Delaware corporation's voting stock, (ii) those affiliates or
associates of a Delaware corporation who were owners of 15% or more of such
corporation's voting stock within the three-year period prior to the date on
which it is sought to be determined whether such person is an interested
stockholder, and (iii) the affiliates or associates of such stockholders. The
Company believes that Knowledge Enterprises, which will have   % of the combined
voting power of the outstanding Common Stock upon consummation of the Offering,
is not such an "interested stockholder."
 
     No Stockholder Action by Written Consent; Special Meetings. The Certificate
of Incorporation provides that stockholder action can only be taken at an annual
or special meeting of stockholders and prohibits stockholder action by written
consent in lieu of a meeting. The Bylaws provide that special meetings of
stockholders may be called only by the Board of Directors, its Chairman or the
President of the Company. Stockholders are not permitted to call a special
meeting of stockholders or to require that the Board of Directors call a special
meeting.
 
     Advance Notice Requirements for Stockholder Proposals and Director
Nominees. The Bylaws establish an advance notice procedure for stockholders to
make nominations of candidates for election as directors or to bring other
business before an annual meeting of stockholders of the Company (the
"Stockholder Notice Procedure"). The Stockholder Notice Procedure provides that
only persons who are nominated by, or at the direction of, the Company's Notice
of Meeting, the Board of Directors or by a stockholder who has given timely
written notice to the Secretary of the Company prior to the meeting at which
directors are to be elected, will be eligible for election as directors of the
Company. The Stockholder Notice Procedure also provides that at an annual
meeting only such business may be conducted as has been brought before the
meeting by, or at the direction of, the Company's Notice of Meeting, the Board
of Directors or by a stockholder who has given timely written notice to the
Secretary of the Company of such stockholder's intention to bring such business
before such meeting. Under the Stockholder Notice Procedure, if a stockholder
desires to submit a proposal or nominate persons for election as directors at an
annual meeting, the stockholder must submit written notice to the Company not
less than 60 days nor more than 90 days prior to the first anniversary of the
previous year's annual meeting (or if the date of the annual meeting is not
within 30 days before or after such anniversary date, then, to be timely, notice
must be delivered not more than 90 nor less than 60 days prior to such annual
meeting or the 10th day after the earlier of (i) the date notice of the meeting
was mailed or (ii) the date a public announcement of the date of such meeting is
first made). In addition, under the Stockholder Notice Procedure, a
stockholder's notice to the Company proposing to nominate a person for election
as a director or relating to the conduct of business other than the nomination
of directors must contain, a brief description of the business desired to be
brought before the meeting, the reasons for conducting such business at the
meeting and any material interest in such business of such stockholder and the
beneficial owner, if any, on whose behalf the nomination or proposal is made. If
the chairman of a meeting
 
                                       55
<PAGE>   57
 
determines that business was not properly brought before the meeting, in
accordance with the Stockholder Notice Procedure, such business shall not be
discussed or transacted.
 
     Number of Directors; Removal; Filling Vacancies. The Bylaws provide that
the Company's Board of Directors will consist of between seven and thirteen
members, the exact number to be fixed from time to time by resolution adopted by
the affirmative vote of a majority of the directors of the Company. The Board of
Directors currently consists of seven directors. Further, subject to the rights
of the holders of any series of Preferred Stock then outstanding and the
Stockholders Agreement, the Bylaws authorize the Board of Directors to fill
newly created directorships. A director so elected by the Board of Directors
holds office until his successor is elected and qualified. Subject to the rights
of the holders of any series of Preferred Stock then outstanding, the Bylaws
also provide that directors may be removed only for cause and only by the
affirmative vote of holders of 66 2/3% of the outstanding shares of voting
securities then entitled to vote generally in the election of directors, voting
together as a single class. The effect of these provisions is to preclude a
stockholder from removing incumbent directors without cause and simultaneously
gaining control of the Company's Board of Directors by filling the vacancies
created by such removal with its own nominees.
 
     Limitation of Officer and Director Liability and Indemnification
Arrangements. The Company's Certificate of Incorporation provides that an
officer or director of the Company will not be personally liable to the Company
or its stockholders for monetary damages for any breach of his fiduciary duty as
an officer or director, except in certain cases where liability is mandated by
the DGCL. The provision has no effect on any non-monetary remedies that may be
available to the Company or its stockholders, nor does it relieve the Company or
its officers or directors from compliance with federal or state securities laws.
The Bylaws also generally provide that the Company shall indemnify, to the
fullest extent permitted by law, any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit, investigation, administrative hearing or any other proceeding (each, a
"Proceeding") by reason of the fact that he is or was a director or officer of
the Company, or is or was serving at the request of the Company as a director,
officer, employee or agent of another entity, against expenses incurred by him
in connection with such Proceeding. An officer or director shall not be entitled
to indemnification by the Company if (i) the officer or director did not act in
good faith and in a manner reasonably believed to be in, or not opposed to, the
best interests of the Company, or (ii) with respect to any criminal action or
proceeding, the officer or director had no reasonable cause to believe his
conduct was unlawful.
 
     Bylaws. The Bylaws are subject to adoption, amendment, alteration, repeal
or rescission either by (a) the Board of Directors or (b) the affirmative vote
of the holders of not less than 66 2/3% of the total voting power of all
outstanding securities of the Company then entitled to vote generally in the
election of directors, voting together as a single class, at any regular meeting
of the Board of Directors or of the stockholders or at any special meeting of
the Board of Directors or of the stockholders if notice of such adoption,
amendment, alteration, repeal or rescission is contained in the notice of such
special meeting.
 
TRANSFER AGENT AND REGISTRAR
 
     The Transfer Agent and Registrar for the Class A Common Stock will be

                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon the closing of the Offering, the Company will have
shares of Class A Common Stock and           shares of Class B Common Stock
outstanding, assuming no exercise of the Underwriters' over-allotment option and
no exercise of outstanding options to purchase Class A Common Stock. Of these
shares, the                shares of Class A Common Stock sold in the Offering
are freely tradable without restriction or further registration under the
Securities Act, except that any shares held by "affiliates" of the Company, as
that term is defined in Rule 144 under the Securities Act ("Rule 144"), may
generally be sold only in compliance with the limitations of Rule 144 described
below.
 
SALE OF RESTRICTED SHARES
 
     The remaining shares of Common Stock (including Class A Common Stock
issuable upon exchange of the Exchangeable Shares) are "restricted securities"
as defined under Rule 144. Restricted Securities may be sold in the public
market only if registered or if they qualify for an exemption from registration
under the Securities Act. Additionally, Nextera's Certificate of Incorporation
provides that each holder of Common Stock, other than the holders of the shares
of Common Stock acquired in the Offering, agrees not to sell, directly or
indirectly, any Common Stock, subject to certain exceptions, without the prior
consent of DLJ for a period of 180 days from the date of this Prospectus.
Subject to the Lock-up Agreements described below and the foregoing provisions
of the Company's Certificate of Incorporation, additional shares of Class A
Common Stock (including Class A Common Stock issuable upon conversion of Class B
Common Stock and the exchange of the Exchangeable Shares) will be available for
sale in the public market (subject in certain circumstances to compliance with
certain volume and other restrictions under Rule 144) as follows: (i)
               shares will be eligible for sale 180 days after the date of this
Prospectus; and (ii)                shares will become eligible thereafter for
sale under Rule 144 upon the expiration of the applicable one-year holding
periods. In addition, if the restrictions of the Lock-up Agreements described
below and the foregoing provisions of the Company's Certificate of Incorporation
were waived in full on the date hereof: (i)                shares of Common
Stock would be eligible for sale in the public market from and after the date of
this Prospectus, and (ii)                shares of Common Stock would be
eligible for sale in the public market 90 days after the date of this
Prospectus.
 
     In general, under Rule 144, a person (or persons whose shares are
aggregated) including an affiliate, who has beneficially owned shares for at
least one year is entitled to sell, within any three-month period commencing 90
days after the date of this Prospectus, a number of shares of Common Stock that
does not exceed the greater of (i) 1% of the then outstanding shares of Class A
Common Stock (approximately                shares as of the date of this
Prospectus) or (ii) the average weekly trading volume in the Class A Common
Stock during the four calendar weeks preceding the date on which notice of such
sale is filed, subject to certain restrictions. In addition, a person who is not
deemed to have been an affiliate of the Company at any time during the 90 days
preceding a sale and who has beneficially owned the shares proposed to be sold
for at least two years, would be entitled to sell such shares under Rule 144(k)
without regard to the volume limitations described above.
 
     An employee, officer or director of or consultant to the Company who
purchased his or her shares pursuant to a written compensatory plan or contract
is entitled to rely on the resale provisions of Rule 701 under the Securities
Act, which permits non-affiliates to sell their Rule 701 shares without having
to comply with the public information, holding period, volume limitation or
notice provisions of Rule 144 and permits affiliates to sell their Rule 701
shares without having to comply with Rule 144's holding period restrictions, in
each case commencing 90 days after the date of this Prospectus.
 
OPTIONS
 
     Upon consummation of the Offering, the Company will have outstanding
options for                shares of Class A Common Stock, of which
               are exercisable. Following the Offering, the Company intends to
file a Registration Statement on Form S-8 under the Securities Act to register
the                shares of Class A Common Stock that are issuable upon the
exercise of stock options either
 
                                       57
<PAGE>   59
 
outstanding or available for grant pursuant to the 1998 Equity Participation
Plan. Such Registration Statement will become effective immediately upon filing;
however, consistent with the terms of the 1998 Equity Participation Plan,
holders of options will be unable to sell any shares of Class A Common Stock
received upon the exercise of options granted thereunder until the expiration of
180 days after the date of this Prospectus without the prior written consent of
DLJ. Shares covered by such Registration Statement will be eligible for sale in
the public market after the effective date of such Registration, subject to Rule
144 limitations applicable to affiliates as well as to the limitations on sale
and vesting described above.
 
REGISTRATION RIGHTS
 
     Stockholders holding an aggregate of                shares of Class A
Common Stock (including shares of Class A Common Stock issuable upon conversion
of Class B Common Stock and exchange of the Exchangeable Shares) ("Holders") are
entitled to certain registration rights under the Stockholders Agreement.
Commencing 180 days after the Offering, Knowledge Enterprises or an affiliate
that then owns an equity interest in the Company may make a one-time written
request of the Company for registration with the Securities and Exchange
Commission (a "Demand Registration") of all or part of its Class A Common Stock
of the Company, provided, however, that the Company need not effect a Demand
Registration unless it includes at least 10% of the Company's issued and
outstanding Common Stock. The Company may defer such Demand Registration for a
single period not to exceed 180 days, if the Board of Directors determines in
the exercise of its reasonable judgment that effecting such Demand Registration
at such time would have a material adverse effect on the Company. In addition,
Holders who together hold at least 10% of the issued and outstanding Common
Stock of the Company may make a one-time written request of the Company for a
Demand Registration on the same terms as those applicable to Knowledge
Enterprises as set forth above.
 
     The Stockholders Agreement also provides piggyback registration rights to
Holders for their shares of Class A Common Stock ("Registrable Securities"). The
Company must provide prior written notice to those Holders whenever it proposes
to register any Common Stock (or securities convertible into or exchangeable
for, or options to purchase, Common Stock) with the Securities and Exchange
Commission on a form that would permit the registration of Registrable
Securities. The Company will register in such registration all Registrable
Securities requested to be included, provided that if, in the opinion of the
applicable underwriter, the number of securities proposed to be included is
greater that what could be sold without having a material impact on the
offering, the Company will include securities in the following priority: (i)
first, the Common Stock the Company proposes to sell, and (ii) second, the
Registrable Securities requested to be included in such registration by the
holders of Registrable Securities pro rata based on the number of Registrable
Securities that each such stockholder shall have requested to include therein.
 
     The Stockholders Agreement further provides that the Company will bear all
expenses incident to the Company's performance of its registration obligations,
other than the costs or expenses of any selling stockholders for underwriters'
commissions, brokerage fees or transfer taxes, or the fees and expenses of any
counsel, accountants or other representative retained by any selling
stockholder. The Company is obligated, however, to reimburse the selling
stockholders in each Demand Registration for the reasonable fees of one counsel
up to $25,000.
 
EFFECT OF SALES OF SHARES
 
     Prior to the Offering, there has been no public market for the Class A
Common Stock, and no precise prediction can be made as to the effect, if any,
that market sales of shares of Class A Common Stock or the availability of
shares of Class A Common Stock for sale will have on the market price of the
Class A Common Stock prevailing from time to time. Nevertheless, the sale of
substantial amounts of the Class A Common Stock in the public market could
adversely affect prevailing market prices and could impair the Company's future
ability to raise capital through the sale of its equity securities.

LOCK-UP AGREEMENTS
 
     All directors, officers and stockholders of the Company have agreed that
they will not, without the prior written consent of DLJ and subject to certain
exceptions, sell or otherwise dispose of any shares of Common Stock or options
to acquire shares of Common Stock during the 180-day period following the date
of this Prospectus. The Company has agreed not to sell or otherwise dispose of
any shares of Class A Common Stock during the 180-day period following the date
of this Prospectus without the prior written consent of DLJ, except the Company
may (i) issue, and grant options to purchase, shares of Class A Common Stock
under the 1998 Equity Participation Plan and (ii) issue shares of Class A Common
Stock in connection with acquisitions, if the terms of such issuance provide
that such Class A Common Stock shall not be resold prior to the expiration of
such 180-day period. DLJ may release any or all shares from Lock-Up Agreements
at any time or from time to time without notice.

     Subject to the terms and conditions of an Underwriting Agreement, dated
            , 1998 (the "Underwriting Agreement"), the Underwriters named below,
who are represented by Donaldson, Lufkin & Jenrette Securities Corporation,
BancBoston Robertson Stephens Inc., BT Alex. Brown Incorporated, and NationsBanc
Montgomery Securities LLC (collectively, the "Representatives"), have severally
agreed to purchase from the Company the respective number of shares of Class A
Common Stock set forth opposite their names below.

     The Underwriting Agreement provides that the obligations of the several
Underwriters to purchase and accept delivery of the shares of Class A Common
Stock offered hereby are subject to approval by their counsel of certain legal
matters and to certain other conditions. The Underwriters are obligated to
purchase and accept delivery of all the shares of Class A Common Stock offered
hereby (other than those shares covered by the over-allotment option described
below) if any are purchased.
 
     The Underwriters initially propose to offer the shares of Class A Common
Stock in part directly to the public at the initial public offering price set
forth on the cover page of this Prospectus and in part to certain dealers
(including the Underwriters) at such price less a concession not in excess of
$     per share. The Underwriters may allow, and such dealers may re-allow, to
certain other dealers a concession not in excess of $     per share. After the
initial offering of the Class A Common Stock, the public offering price and
other selling terms may be changed by the Representatives at any time without
notice. The Underwriters do not intend to confirm sales to any accounts over
which they exercise discretionary authority.
 
     The Company has granted to the Underwriters an option, exercisable within
30 days after the date of this Prospectus, to purchase, from time to time, in
whole or in part, up to an aggregate of                additional shares of
Class A Common Stock at the initial public offering price less underwriting
discounts and commissions. The Underwriters may exercise such option solely to
cover over-allotments, if any, made in connection with the Offering. To the
extent that the Underwriters exercise such option, each Underwriter will become
obligated, subject to certain conditions, to purchase its pro rata portion of
such additional shares proportionate to such Underwriter's underwriting
commitment as indicated in the preceding table.
 
     The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act, or to contribute to
payments that the Underwriters may be required to make in respect thereof.
 
     Effective August 31, 1998, the Company and Nextera Funding, Inc., an
affiliate of DLJ, entered into the Bridge Loan, which provides for a $40 million
revolving credit facility which bears interest at the rate of LIBOR plus 450
basis points (10.2% on August 31, 1998) per annum, and matures on February 28,
1999. The Company borrowed $38.0 million under the Bridge Loan to finance the
Sibson Acquisitions. The indebtedness incurred under the Bridge Loan will be
repaid with a portion of the net proceeds from the Offering. As a result of such
arrangements, the Conduct Rules of the National Association of Securities
Dealers, Inc. require that the initial public offering price of the Class A
Common Stock be no higher than that recommended by a qualified independent
underwriter, as defined in Rule 2720 of the Conduct Rules. BT Alex. Brown

Incorporated, one of the Representatives of the Underwriters, will serve as the
qualified independent underwriter and has assumed the responsibilities of acting
as qualified independent underwriter in pricing the Class A Common Stock offered
hereby and conducting "due diligence" in respect thereto. BT Alex. Brown
Incorporated will receive a fee of $5,000 from the Company as compensation to
act as qualified independent underwriter.
 
     DLJ and the Company are parties to a letter agreement dated August 31, 1998
(the "Engagement Letter"). Pursuant to the Engagement Letter, DLJ has the right
to act as the Company's lead placement agent, lead initial purchaser or lead
managing underwriter in the event that the Company determines to sell its
securities with the services of an outside financial advisor or investment bank
during the period ending August 31, 1999.
 
     Each of the Company, its executive officers and directors and shareholders
of the Company has agreed, subject to certain exceptions, not to (i) offer,
pledge, sell, contract to sell, sell any option or contract to purchase,
purchase any option or contract to sell, grant any option, right or warrant to
purchase or otherwise transfer or dispose of, directly or indirectly, any shares
of Class A Common Stock or any securities convertible into or exercisable or
exchangeable for Class A Common Stock or (ii) enter into any swap or other
arrangement that transfers all or a portion of the economic consequences
associated with the ownership of any Class A Common Stock (regardless of whether
any of the transactions described in clause (i) or (ii) is to be settled by the
delivery of Class A Common Stock, or such other securities, in cash or
otherwise) for a period of 180 days after the date of this Prospectus without
the prior written consent of DLJ. In addition, during such period, the Company
has also agreed not to file any registration statement with respect to, and each
of its executive officers, directors and certain shareholders of the Company has
agreed not to make any demand for, or exercise any right with respect to, the
registration of any shares of Class A Common Stock or any securities convertible
into or exercisable or exchangeable for Class A Common Stock without DLJ's prior
written consent.
 
     Prior to the Offering, there has been no established trading market for the
Class A Common Stock. The initial public offering price for the shares of Class
A Common Stock offered hereby will be determined by negotiation among the
Company and the Representatives. The factors to be considered in determining the
initial public offering price include the history of and the prospects for the
industry in which the Company competes, the prospects for future earnings of the
Company, the recent market prices of securities of generally comparable
companies and the general condition of the securities markets at the time of the
Offering.
 
     Other than in the United States, no action has been taken by the Company or
the Underwriters that would permit a public offering of the shares of Class A
Common Stock offered hereby in any jurisdiction where action for that purpose is
required. The shares of Class A Common Stock offered hereby may not be offered
or sold, directly or indirectly, nor may this Prospectus or any other offering
material or advertisements in connection with the offer and sale of any such
shares of Class A Common Stock be distributed or published in any jurisdiction,
except under circumstances that will result in compliance with the applicable
rules and regulations of such jurisdiction. Persons into whose possession this
Prospectus comes are advised to inform themselves about and to observe any
restrictions relating to the Offering and the distribution of this Prospectus.
This Prospectus does not constitute an offer to sell or a solicitation of an
offer to buy any shares of Class A Common Stock offered hereby in any
jurisdiction in which such an offer or a solicitation is unlawful.
 
     In connection with the Offering, the Underwriters may engage in
transactions that stabilize, maintain or otherwise affect the price of the Class
A Common Stock. Specifically, the Underwriters may overallot the Offering,
creating a syndicate short position. The Underwriters may bid for and purchase
shares of Class A Common Stock in the open market to cover such syndicate short
position or to stabilize the price of the Class A Common Stock. In addition, the
underwriting syndicate may reclaim selling concessions from syndicate members
and selected dealers if they repurchase previously distributed Class A Common
Stock in syndicate covering transactions, in stabilizing transactions or
otherwise. These activities may stabilize or maintain the market price of the
Class A Common Stock above independent market levels. The Underwriters are not
required to engage in these activities, and may end any of these activities at
any time.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
Board of Directors
Nextera Enterprises, L.L.C.
 
     We have audited the accompanying consolidated balance sheet of Nextera
Enterprises, L.L.C. (the Company) as of December 31, 1997, and the related
consolidated statements of operations, members' equity and cash flows for the
period from February 26, 1997 (date of inception) through December 31, 1997.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Nextera
Enterprises, L.L.C. at December 31, 1997, and the results of its operations and
its cash flows for the period from February 26, 1997 (date of inception) through
December 31, 1997 in conformity with generally accepted accounting principles.

</TABLE>
 
     The aggregate purchase price was $26,565,000, which consisted of
$25,877,000 in cash and the issuance of 1,469,667 Class A Common Units, as well
as the assumption of certain liabilities. One of the acquisition agreements
contains an earn-out provision providing for the payment of up to an additional
$800,000 in cash and 53,333 Class A Common Units of the Company upon the
achievement of certain revenue and pretax profit targets. The Company's goodwill
will be adjusted for any additional consideration earned.
 
     The acquisitions have been accounted for under the purchase method of
accounting. Accordingly, the purchase price was allocated to the underlying
assets and liabilities based on their respective estimated fair values at the
date of the acquisition.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
Principles of Consolidation
 
     The consolidated financial statements include the accounts of the Company
and its subsidiaries. All significant intercompany accounts and transactions
have been eliminated in consolidation.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
Interim Financial Statements (Unaudited)
 
     The balance sheet at June 30, 1998, and the statements of operations,
members' equity (deficit) and cash flows for the period from February 26, 1997
(inception) to June 30, 1997 and the six months ended June 30, 1998 are
unaudited, and, in the opinion of management, include all adjustments,
consisting only of normal recurring adjustments, necessary for a fair
presentation of the Company's consolidated financial position, results of
operations and cash flows.
 
Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the reported
period. Actual results could differ from those estimates.
 
Revenue Recognition
 
     The Company derives its revenues from consulting services under time and
materials, capped-fee and fixed-price billing arrangements. Under time and
materials arrangements, revenues are recognized as the services are provided.
Revenues on fixed-price and capped-fee contracts are recognized using the
percentage of completion method of accounting and are adjusted monthly for the
cumulative impact of any revision in estimates. The Company determines the
percentage of completion of its contracts by comparing costs incurred to date to
total estimated costs. Contract costs include all direct labor and expenses
related to the contract performance. Costs and estimated earnings in excess of
billings represents revenues recognized in excess of amounts billed. Deferred
revenue represents billings in excess of revenues recognized. Net revenues
exclude reimbursable expenses charged to clients.
 
Cash and Cash Equivalents
 
     Cash and cash equivalents consist of cash on hand and demand deposits
accounts. The Company considers all highly liquid investments with a maturity of
three months or less when purchased to be cash equivalents. Cash equivalents are
stated at cost, which approximates market value.
 
Property and Equipment
 
     Property and equipment are stated at cost. Depreciation is provided using
the straight-line method over the estimated useful lives of the assets as
follows:
 
<TABLE>
<S>                                                 <C>
Furniture and fixtures............................   5-7 years
Equipment.........................................   3-5 years
Software..........................................     3 years
</TABLE>
 
     Leasehold improvements are amortized over the lesser of the lease term or
the useful life of the property.
 
Intangible Assets
 
     Intangible assets consist principally of the cost in excess of assets
acquired resulting from acquisitions and are being amortized on a straight-line
basis over 5 years for intangibles relating to personnel and over 40 years for
all other intangibles. The Company periodically evaluates the carrying value of
intangible assets for impairment. Any impairment is charged to expense in the
period in which the impairment is incurred.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
Financial Instruments
 
     The carrying value of financial instruments such as cash equivalents,
accounts receivable, accounts payable and accrued expenses approximate their
fair values based on the short-term maturities of these instruments. The
carrying value of long-term debt approximates its fair value based on references
to similar instruments.
 
Concentration of Credit Risk
 
     The Company provides its services to customers in diversified industries,
primarily in the United States. The Company performs ongoing credit evaluations
of its customers and generally does not require collateral. The Company
maintains reserves for potential credit losses and such losses have been within
management's expectations. Sales to three significant customers accounted for
36%, 20% and 10% of net revenues during 1997. Two significant customers
accounted for 51% and 21% of receivables, net of related deferred revenue, at
December 31, 1997, respectively.
 
Basic and Diluted Earnings Per Common Unit
 
     On December 31, 1997, the Company adopted Statement of Financial Accounting
Standard No. 128, Earnings Per Share ("SFAS No. 128"). SFAS No. 128 requires the
presentation of two amounts, basic earnings per common unit and diluted earnings
per common unit. Earnings per common unit excludes any dilutive effects of
options, warrants and convertible securities. For the period ended December 31,
1997, basic and diluted earnings per common unit are the same due to the
antidilutive effect of potential common units outstanding.
 
Income Taxes
 
     Nextera is treated as a partnership for federal and state income tax
purposes. Therefore, all items of income, expense, and tax credit are passed
through to the individual unit holders. Accordingly, no provision for income
taxes is required for Nextera. Symmetrix, the Company's wholly owned subsidiary,
is subject to income taxes and reports its income tax provision using the
liability method in accordance with Financial Accounting Standards Board
Statement 109, Accounting for Income Taxes ("Statement 109"). Under Statement
109, deferred income taxes are provided for differences between the financial
reporting and tax bases of assets and liabilities at income tax rates expected
to be in effect when the taxes are actually paid or recovered.
 
Effect of Recent Accounting Pronouncements
 
     During 1997, the Financial Accounting Standards Board issued Statement No.
130, Reporting Comprehensive Income ("Statement 130"). The Company will adopt
the provisions of Statement 130 during fiscal year 1998. At that time, the
Company will be required to disclose comprehensive income. Comprehensive income
is generally defined as all changes in members' equity (deficit) exclusive of
transactions with owners such as capital investments and dividends. Management
of the Company does not expect the adoption of Statement 130 will have a
material impact on the Company's financial statement disclosures.
 
     In June 1997, the Financial Accounting Standards Board issued Statement No.
131, Disclosures About Segments of an Enterprise and Related Information
("Statement 131"), which is required to be adopted for years beginning after
December 15, 1997. Management of the Company believes that they operate in only
one segment and accordingly does not expect the adoption of Statement 131 will
have a material impact on the Company's financial statement disclosures.

     Symmetrix has approximately $5,819,000 of pre-acquisition net operating
loss carryforwards which expire through the year 2012. The net operating loss
carryforwards arose principally as a result of disqualifying dispositions of
Symmetrix' previously outstanding stock options. As a result of ownership
changes, these net operating losses are subject to limitations under the
Internal Revenue Code.

7. RELATED PARTY TRANSACTIONS
 
     During 1997, the Company entered into a professional services contract with
Product Point International, Inc. ("PPI"), a subsidiary of Knowledge Universe,
L.L.C. Revenues from PPI were $225,000 through December 31, 1997. At December
31, 1997, $225,000 was due from PPI.
 
     On July 31, 1995, Symmetrix entered into a four year non-compete agreement
("Agreement") with its then majority stockholder ("Stockholder") in conjunction
with the Stockholder's sale of his holdings in Symmetrix' common stock to a
non-affiliated third party. Symmetrix capitalized the value of the Agreement,
$986,000, and is amortizing the amount on a straight-line basis over the life of
the Agreement. At December 31, 1997, the carrying amount was $390,000 and was
included in other assets on the consolidated balance sheet.

9. MEMBERS' EQUITY
 
     The accompanying financial statements reflect the Company's historical
equity structure which is described below. As of April 30, 1998, the Company
amended and restated its capital structure (see Recapitalization below).
 
Historical
 
     As of December 31, 1997, the Company was authorized to issue two classes of
Units: Class A Common Units and Class B Preferred Units, to be owned by unit
holders of the limited liability company ("Members"). Each Class A Common Member
had one vote per Class A Common Unit owned by such Member. The Class B Preferred
Units were non-voting. At December 31, 1997, the Company had a warrant
outstanding to purchase 5,000,000 Class A Common Units at an exercise price of
$2.50 per unit, with an expiration date of August 1, 2002 (the "Warrant"). At
any time after May 1, 2002, or upon the exercise of the Warrant, the Class B
Preferred Members have the right to require the Company to redeem all of their
Class B Preferred Units for an amount equal to their adjusted capital balances.
The Class B Preferred Units also had a liquidation preference equal to their
Undistributed Return, as defined in the amended and restated Nextera operating
agreement. The Company had a right to approve or disapprove any proposed
transfer of Units.
 
Recapitalization
 
     During the period from January 1, 1998 through April 30, 1998, $30,223,000
of additional capital was contributed, bringing the total contributed capital to
$49,970,000. As of April 30, 1998, the Company undertook a recapitalization,
which was unanimously approved by all of the Members of the Company. The net
result of the recapitalization was the redesignation of $47,970,000 of capital
as debentures. As a result of the recapitalization transactions, the Company
issued two debentures with principal amounts of $24,970,000 and $23,000,000,
respectively. Both debentures are due on May 1, 2002. The debentures accrue
interest at a rate of 10% retroactive to the date the initial capital was
funded. Accordingly, for the six months ended June 30, 1998, the Company
incurred approximately $793,000 of interest expense pursuant to the
recapitalization related to the period ended December 31, 1997. The stated value
of the 10,000,000 Class A Common Units was reduced to $0.20 per unit from $2.50
per unit.
 
     In addition, pursuant to the recapitalization, the warrant to acquire
5,000,000 Class A Common Units was amended to provide that the units subject to
the warrant were changed to a new class of authorized Class B Common Units. The
Class B Common Units have the same economic characteristics as the Class A
Common Units, except that each Class B Common Member has ten votes per Class B
Common Unit owned

by such member. The warrant was contributed to the Company in exchange for
4,300,000 Class B Common Units on April 30, 1998.
 
Employee Equity Participation Plan
 
     In 1997, the Company established its Employee Equity Participation Plan
("EPP"), whereby the Board of Directors may make discretionary awards of stock
appreciation rights ("SAR") to employees of the Company. At the exercise date,
the Company may settle its SAR obligations by making either cash payments or
issuing Class A Common Units equal to the amount of the underlying appreciated
value of the Company's Class A Common Unit from the initial grant date. The
exercise of the SAR is limited by the provisions of each applicable employee
agreement, however, the exercise period cannot exceed seven years. For the
period ended December 31, 1997, 450,000 SARs were granted under the EPP, at an
initial price of $5.00. The Company recognized no compensation expense relating
to the SARs during the period ended December 31, 1997. Pursuant to the EPP,
4,500,000 SARs have been reserved for issuance.
 
     Subsequent to December 31, 1997, the Board of Directors approved the
conversion of all existing SARs into options pursuant to the provisions of the
EPP. The exercise price of the options was $5.00, which was equal to or exceeded
the fair value on the date of the conversion.

11. RETIREMENT SAVINGS PLAN
 
     The Company's subsidiary sponsors a Retirement Savings Plan (the
"Retirement Plan") under Section 401(k) of the Internal Revenue Code for the
benefit all of its employees meeting certain minimum service requirements.
Eligible employees may elect to contribute to the Retirement Plan subject to
limitations established by the Internal Revenue Code. The trustees of the plan
select investment opportunities from which participants may choose to
contribute. Matching contributions are made at the discretion of the Company.
There were no contributions to the Retirement Plan by the Company for the period
from February 26, 1997 (date of inception) through December 31, 1997.
 
12. SUBSEQUENT EVENTS
 
     Effective August 31, 1998, the Company acquired the assets and assumed
certain liabilities of Sibson & Company, L.P. and Sibson Canada, Inc.
(collectively, "Sibson") for cash of $37,375,000 and 2,810,900 Class A Common
Units (including the Exchangeable Shares, defined below). The acquisition of
Sibson was accounted for under the purchase method of accounting; accordingly,
the purchase price was allocated to the underlying assets and liabilities based
on their respective estimated fair values at the date of the acquisition.
 
     In connection with the acquisition of Sibson, the Company formed a wholly
owned Canadian subsidiary, Sibson Acquisition Co., which issued 197,813
Exchangeable Preference Shares ("Exchangeable Shares") to the holders of capital
stock of Sibson Canada, Inc. The Exchangeable Shares are exchangeable at any
time by the holders thereof for Class A Common Units. The holders of
Exchangeable Shares are entitled to dividend

and other rights equivalent to holders of Class A Common Units but are not
entitled to vote on matters submitted to the holders of Class A Common Units
until such time as the holders of Exchangeable Shares exchange such shares for
Class A Common Units.
 
     Also, in connection with the acquisition of Sibson, the Company secured a
$40,000,000 revolving credit facility (the "Bridge Loan"), which bears interest
at the rate of LIBOR plus 450 basis points per annum (10.2% at August 31, 1998)
and matures on February 28, 1999. The Bridge Loan is secured by substantially
all of the Company's assets and contains certain restrictive covenants. As of
August 31, 1998, $38,000,000 was outstanding under the Bridge Loan.

Board of Directors
Symmetrix, Inc.
 
     We have audited the accompanying consolidated balance sheets of Symmetrix,
Inc. and subsidiaries as of May 31, 1997 and July 30, 1997, and the related
consolidated statements of operations and accumulated deficit and cash flows for
the year ended May 31, 1997 and for the period from June 1, 1997 through July
30, 1997. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Symmetrix,
Inc. and subsidiaries at May 31, 1997 and July 30, 1997, and the results of
their operations and their cash flows for the year ended May 31, 1997 and for
the period from June 1, 1997 through July 30, 1997 in conformity with generally
accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                         MAY 31, 1997 AND JULY 30, 1997
 
1. THE COMPANY
 
     Symmetrix, Inc. ("Symmetrix" or the "Company") offers enhanced services in
acquisition due diligence, customer profitability, information technology
strategy assessment and design, construction, and deployment of complete
business systems. Symmetrix primarily offers its services to the financial
services, health care and insurance industries.
 
     On May 26, 1994, Symmetrix Capital Partners I Limited Partnership ("the
Partnership") was formed for the purpose of making investments in entities that
could benefit from the Company's management services. In the absence of any
dissolution events, as defined in the Partnership agreement, the Partnership
shall continue in existence until December 31, 2009, unless otherwise extended.
The Company is the general partner and a Class B Limited Partner. As of May 31,
1996, the Company had provided 74% of the Partnership's capital. During the year
ended May 31, 1995, certain Class B Limited Partners were admitted in place of a
portion of the Company's investment as a Class B Limited Partner. A total of
$125,000 was paid to the Company in return for this portion of the Company's
Class B Limited Partnership interest. To date, the Partnership has not generated
any revenues or expenses. Management intends to dissolve the Partnership.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the reported
period. Actual results could differ from those estimates.
 
Revenue Recognition
 
     The Company derives its revenues from consulting services under time and
materials, capped-fee, and fixed-price billing arrangements. Under time and
materials arrangements, revenues are recognized as the services are provided.
Revenues on fixed-price and capped-fee contracts are recognized using the
percentage of completion method of accounting and are adjusted monthly for the
cumulative impact of any revision in estimates. The Company determines the
percentage of completion of its contracts by comparing costs incurred to date to
total estimated costs. Contract costs include all direct labor and expenses
related to the contract performance. Costs and estimated earnings in excess of
billings represents revenues recognized in excess of amounts billed. Deferred
revenue represents billings in excess of revenues recognized. Net revenues
exclude reimbursable expenses charged to clients.
 
Cash and Cash Equivalents
 
     Cash and cash equivalents consist of cash on hand and demand deposits
accounts. The Company considers all highly liquid investments with a maturity of
three months or less when purchased to be cash equivalents. Cash equivalents are
stated at cost which approximates market value.

                         MAY 31, 1997 AND JULY 30, 1997
 
Property and Equipment
 
     Property and equipment are stated at cost. Depreciation is provided using
the straight-line method over the following estimated useful lives:
 
<TABLE>
<S>                                                 <C>
Furniture and fixtures............................  5-7 years
Equipment.........................................  3-5 years
Software..........................................    3 years
</TABLE>
 
     Leasehold improvements are amortized over the lesser of the lease term or
the useful life of the property.
 
Financial Instruments
 
     The carrying value of financial instruments such as cash equivalents,
accounts receivable, accounts payable and accrued expenses approximates their
fair values based on the short-term maturities of these instruments. The
carrying value of long-term debt approximates its fair value based on references
to similar instruments.
 
Concentration of Credit Risk
 
     The Company provides its services to customers in diversified industries,
primarily in the United States. The Company performs ongoing credit evaluations
of its customers and generally does not require collateral. The Company
maintains reserves for potential credit losses and such losses have been within
management's expectations. For the year ended May 31, 1997, revenues to three
significant customers accounted for 69% of net revenues. Three customers
accounted for 84% of receivables, net of related deferred revenue at May 31,
1997.
 
Stock Compensation
 
     The Company grants stock options for a fixed number of shares to employees
with an exercise price not less than the fair value of the shares at the date of
grant and accounts for stock options granted to employees in accordance with the
provisions of Accounting Principle Board Opinion No. 25, Accounting for Stock
Issued to Employees.
 
Income Taxes
 
     The Company utilizes the liability method of accounting for income taxes,
as set forth in Statement of Financial Accounting Standards No. 109, Accounting
for Income Taxes. Under this method, deferred tax liabilities and assets are
recognized for the expected future tax consequences of temporary differences
between the carrying amounts and the tax basis of assets and liabilities.
Deferred tax assets are recognized, net of any valuation allowance, for
deductible temporary differences and net operating loss and tax credit
carryforwards. Deferred tax expense represents the change in the deferred tax
asset or liability balances.
 
3. INVESTMENT
 
     The Company held an investment in Olympic Manufacturing Group, Inc.
("Olympic"), a privately-held manufacturing company. The Company did not have a
controlling interest in Olympic and the investment was valued at cost. The
investment was sold during the year ended May 31, 1997 at a gain of $1,883,927.

     The Company has approximately $5,819,000 of net operating loss
carryforwards which expire through the year 2012. The net operating loss
carryforwards arose principally as a result of disqualifying dispositions of the
Company's previously outstanding stock options. As a result of ownership
changes, these net operating losses are subject to limitations under the
Internal Revenue Code.

10. STOCKHOLDERS' EQUITY
 
Stock Option Plan
 
     The Company established the 1988 Stock Option Plan (the "Plan"), which
provided for the granting of incentive stock options and non-qualified stock
options to employees. The Plan provided for a maximum of 1,415,298 shares of
common stock of the Company to be granted over ten years from the date the Plan
was adopted.
 
     Incentive stock options may be issued under the Plan at an option price not
less than the fair market value at the date of grant as determined by the Board
of Directors (110% of fair market value in the case of stockholders having
ownership in excess of 10%). Non-qualified stock options may be issued under the
Plan at an option price as determined by the Board of Directors at the date of
the grant.
 
     The incentive stock options are exercisable for a period not to exceed ten
years from the date of grant (five years in the case of incentive stock options
for the stockholders having ownership in excess of 10%). The non-qualified
options are exercisable in accordance with the terms agreed for each option
granted.
 
     During the year ended May 31, 1997, the Company granted 112,000 options
with exercise prices equal to or exceeding the fair market value at the date of
grant of the Company's common stock, ranging from $2.55 to $5.05. There were
1,025,558 stock options outstanding at May 31, 1997. No stock options were
granted during the two months ended July 30, 1997.
 
     In July 1997, the Board of Directors approved a stock option repurchase
plan whereby all of the outstanding stock options were canceled. The repurchase
amount was accrued at July 30, 1997 at a cost of $4,126,000, which was charged
to operations in the two months ended July 30, 1997. As a result, no stock

options were outstanding at July 30, 1997. Accordingly, the disclosure of pro
forma net loss required by Statement of Financial Accounting Standards No. 123,
Accounting for Stock-Based Compensation has not been presented because such
information is not deemed to be meaningful. The Plan will expire by its own
terms on September 20, 1998.
 
11. RETIREMENT SAVINGS PLAN
 
     The Company sponsors a Retirement Savings Plan (the "Retirement Plan")
under Section 401(k) of the Internal Revenue Code for the benefit of all
employees meeting certain minimum service requirements. Eligible employees may
elect to contribute to the Retirement Plan subject to limitations established by
the Internal Revenue Code. The trustees of the Retirement Plan select investment
opportunities from which participants may choose to contribute. Matching
contributions are made at the discretion of the Company. The Company made
contributions to the Retirement Plan of $139,000 for the year ended May 31,
1997. There were no contributions to the Retirement Plan by the Company for the
period from June 1, 1997 through July 30, 1997.
 
12. SUBSEQUENT EVENT
 
     Effective July 30, 1997, all of the outstanding stock of the Company was
acquired by Nextera Enterprises, L.L.C. for cash of $15,500,000.

misstatement. An audit includes examining, on a test basis, evidence supporting

1. THE COMPANY
 
     Symmetrix, Inc. ("Symmetrix" or the "Company") offers enhanced services in
acquisition due diligence, customer profitability, information technology
strategy assessment and design construction, and deployment of complete business
systems. Symmetrix primarily offers its services to the financial services,
health care and insurance industries.
 
     On May 26, 1994, Symmetrix Capital Partners I Limited Partnership ("the
Partnership") was formed for the purpose of making investments in entities that
could benefit from the Company's management services. In the absence of any
dissolution events, as defined in the Partnership agreement, the Partnership
shall continue in existence until December 31, 2009, unless otherwise extended.
The Company is the general partner and a Class B Limited Partner. As of May 31,
1996, the Company had provided 74% of the Partnership's capital. During the year
ended May 31, 1995, certain Class B Limited Partners were admitted in place of a
portion of the Company's investment as a Class B Limited Partner. A total of
$125,000 was paid to the Company in return for this portion of the Company's
Class B Limited Partnership interest. To date, the Partnership has not generated
any revenues or expenses.
 
     On January 1, 1995, Symmetrix European Holdings, Inc. ("Symmetrix
Holdings") (a Delaware corporation) and Symmetrix Europe, SA ("Symmetrix
Europe") (a French corporation) were formed for the purpose of conducting
business in Europe. The Company holds 80% of the outstanding stock of Symmetrix
Holdings, which holds 99.9% of the outstanding stock of Symmetrix Europe.
Activity for these subsidiaries has been consolidated into the Company's
financial statements for the year ended May 31, 1996. In November 1995, the
Board of Directors approved the abandonment of the operating activities of
Symmetrix Holdings and Symmetrix Europe.
 
     The Partnership, Symmetrix Holdings and Symmetrix Europe have calendar
year-ends and thus for purposes of consolidation, the accounts of these
subsidiaries are based on a period which corresponds with the fiscal period of
the Company.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
Principles of Consolidation
 
     The consolidated financial statements include the accounts of the Company
and its subsidiaries. All significant intercompany accounts and transactions
have been eliminated in consolidation.
 
Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the reported
period. Actual results could differ from those estimates and assumptions.
 
Foreign Currency Translation and Transaction Gains and Losses
 
     Assets and liabilities of the Company's foreign operation are translated
into U.S. dollars at the exchange rate in effect as of the balance sheet date
and revenue and expenses are translated at average exchange rates during the
period. The resultant translation adjustment is reflected as a separate
component of stockholders' equity. Transaction gains and losses are reflected in
the consolidated statement of operations.

                                  MAY 31, 1996
 
Revenue Recognition
 
     The Company derives its revenues from consulting services under time and
materials, capped-fee and fixed-price billing arrangements. Under time and
materials arrangements, revenues are recognized as the services are provided.
Revenues on fixed-price and capped-fee contracts are recognized using the
percentage of completion method of accounting and are adjusted monthly for the
cumulative impact of any revision in estimates. The Company determines the
percentage of completion of its contracts by comparing costs incurred to date to
total estimated costs. Contract costs include all direct labor and expenses
related to the contract performance. Costs and estimated earnings in excess of
billings represents revenues recognized in excess of amounts billed from
fixed-price contracts. Deferred revenue represents billings in excess of
revenues earned. Revenues include reimbursable expenses charged to clients.
 
Cash and Cash Equivalents
 
     Cash and cash equivalents consist of cash on hand and demand deposit
accounts. The Company considers all highly liquid investments with a maturity of
three months or less when purchased to be cash equivalents. Cash equivalents are
stated at cost which approximates market value. The Company's cash equivalents
consist of an overnight repurchase agreement that is managed by a financial
institution with a strong credit rating. Accordingly, management believes the
investment is subject to minimal credit and market risk.
 
Property and Equipment
 
     Property and equipment are stated at cost. Depreciation is provided using
the straight-line method over the following estimated useful lives:
 
<TABLE>
<S>                                                <C>
Furniture and fixtures...........................   5-7 years
Equipment........................................   3-5 years
Software.........................................     3 years
</TABLE>
 
     Leasehold improvements are amortized over the lesser of the lease term or
the useful life of the property.
 
Financial Instruments
 
     The carrying value of financial instruments such as cash equivalents,
accounts receivable, accounts payable and accrued expenses approximates their
fair values based on short-term maturities of these instruments. The carrying
value of long-term debt approximates its fair value based on references to
similar instruments.
 
Concentration of Significant Customers
 
     The Company provides its services to customers in diversified industries,
primarily in the United States. The Company performs ongoing credit evaluations
of its customers and generally does not require collateral. The Company
maintains reserves for potential credit losses and such losses have been within
management's expectations. Sales to four significant customers accounted for
14%, 14%, 13% and 13%, respectively, of revenues for the year ended May 31,
1996.
 
Income Taxes
 
     The Company utilizes the liability method of accounting for income taxes,
as set forth in Statement of Financial Accounting Standards No. 109, Accounting
for Income Taxes. Under this method, deferred tax liabilities and assets are
recognized for the expected future tax consequences of temporary differences
between the carrying amounts and the tax basis of assets and liabilities.
Deferred tax assets are recognized, net of any valuation allowance, for
deductible temporary differences and net operating loss and tax credit
carryforwards. Deferred tax expense represents the change in the deferred tax
asset or liability balances.

3. INVESTMENT
 
     The Partnership has an investment in Olympic Manufacturing Group, Inc.
("Olympic"), a privately held manufacturing company. The Company does not have a
controlling interest in Olympic and the investment is carried at cost. The value
of $499,966 does not necessarily represent an amount which would be realized

less than the fair market value at the date of grant as determined by the Board
of Directors (110% of fair market value in the case of stockholders having
ownership in excess of 10%). Non-qualified stock options may be issued under the
Plan at an option price as determined by the Board of Directors at the date of
the grant.
 
     The incentive stock options are exercisable for a period not to exceed ten
years from the date of grant (five years in the case of incentive stock options
for the stockholders having ownership in excess of 10%). The non-qualified
options are exercisable in accordance with the terms agreed for each option
granted.

1. THE COMPANY
 
     Symmetrix, Inc. ("Symmetrix" or the "Company"), offers enhanced services in
acquisition due diligence, customer profitability, information technology
strategy assessment and design, construction, and deployment of complete
business systems. Symmetrix primarily offers its services to the financial
services, health care and insurance industries.
 
     On May 26, 1994, Symmetrix Capital Partners I Limited Partnership (the
"Partnership") was formed for the purpose of making investments in entities that
could benefit from the Company's management services. In the absence of any
dissolution events, as defined in the partnership agreement, the Partnership
shall continue in existence until December 31, 2009, unless otherwise extended.
The Company is the general partner and a Class B Limited Partner. As of May 31,
1995, the Company had provided 74% of the Partnership's capital. During fiscal
year 1995, certain Class B Limited Partners were admitted in place of a portion
of the Company's investment as a Class B Limited Partner. A total of $125,000
was paid to the Company in return for this portion of the Company's Class B
Limited Partnership interest. To date, the Partnership has not generated any
income, loss or expenses.
 
     On January 1, 1995, Symmetrix European Holdings, Inc. ("Symmetrix
Holdings") (a Delaware corporation company) and Symmetrix Europe, SA ("Symmetrix
Europe") (a French corporation) were formed for the purpose of conducting
business in Europe. The Company holds 80% of the outstanding stock of Symmetrix
Holdings, which holds 99.9% of the outstanding stock of Symmetrix Europe.
Activity for these subsidiaries has been consolidated into the Company's
financial statements for the year ended May 31, 1995.
 
     The Partnership, Symmetrix Holdings and Symmetrix Europe have calendar
year-ends and thus for purposes of consolidation, the accounts of these
subsidiaries are based on a period which corresponds with the fiscal period of
the Company.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
Principles of Consolidation
 
     The consolidated financial statements include the accounts of the Company
and its subsidiaries. All significant intercompany accounts and transactions
have been eliminated in consolidation.
 
Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the reported
period. Actual results could differ from those estimates.
 
Foreign Currency Translation and Transaction Gains and Losses
 
     Assets and liabilities of the Company's foreign operation are translated
into U.S. dollars at the exchange rate in effect as of the balance sheet date
and revenues and expenses are translated at average exchange rates during the
period. The resultant translation adjustment is reflected as a separate
component of stockholders' equity on the balance sheet. Transaction gains and
losses are reflected in the consolidated statement of operations.

                                  MAY 31, 1995
 
Revenue Recognition
 
     The Company derives its revenues from consulting services under time and
materials, capped-fee and fixed-price billing arrangements. Under time and
materials arrangements, revenues are recognized as the services are provided.
Revenues on fixed-price and capped-fee contracts are recognized using the
percentage of completion method of accounting and are adjusted monthly for the
cumulative impact of any revision in estimates. The Company determines the
percentage of completion of its contracts by comparing costs incurred to date to
total estimated costs. Contract costs include all direct labor and expenses
related to the contract performance. Costs and estimated earnings in excess of
billings represents revenues recognized in excess of amounts billed from
fixed-price contracts. Deferred revenue represents billings in excess of
revenues recognized. Revenues include reimbursable expenses charged to clients.
 
Cash and Cash Equivalents
 
     Cash and cash equivalents consist of cash on hand and demand deposit
accounts. The Company considers all highly liquid investments purchased with a
maturity of three months or less to be cash equivalents. Cash equivalents are
stated at cost which approximates market value. The Company's investments
consist of an overnight repurchase agreement that is managed by a financial
institution with a strong credit rating. Accordingly, the investment is subject
to minimal credit and market risk.
 
Property and Equipment
 
     Property and equipment are stated at cost. Depreciation is provided using
the straight-line method over the following estimated useful lives:

Furniture and fixtures......................................  5-7 years
Equipment...................................................  3-5 years
Software....................................................    3 years
</TABLE>
 
     Amortization expense related to equipment under capital leases was $18,934
for the year ended May 31, 1995.
 
Concentration of Credit Risk and Significant Customers
 
     The Company provides its services to customers in diversified industries,
primarily in the United States. The Company performs ongoing credit evaluations
of its customers and generally does not require collateral. The Company
maintains reserves for potential credit losses and such losses have been within
management's expectations. Sales to two significant customers accounted for 26%
and 12%, respectively, of revenues for the year ended May 31, 1995.
 
Income Taxes
 
     The Company utilizes the liability method of accounting for income taxes,
as set forth in Statement of Financial Accounting Standards No. 109, Accounting
for Income Taxes. Under this method, deferred tax liabilities and assets are
recognized for the expected future tax consequences of temporary differences
between the carrying amounts and the tax basis of assets and liabilities.
Deferred tax assets are recognized, net of any valuation allowance, for
deductible temporary differences and net operating loss and tax credit
carryforwards. Deferred tax expense represents the change in the deferred tax
asset or liability balances.

3. PROFIT SHARING PLAN
 
     Commencing in 1990, the Company made distributions to employees under a
discretionary profit sharing plan. Profit sharing expense was $396,716 in 1995.

Notes payable in the amount of $226,800 were issued in connection with the
purchase of the 1994 shares. The shares have been held in treasury at cost and
it is the Company's intention that these shares be available for issuance under
the 1988 Stock Option Plan.
 
5. STOCK OPTIONS
 
     The Company established the 1988 Stock Option Plan (the "Plan"), which
provided for the granting of incentive stock options and non-qualified stock
options to employees of the Company. The Plan currently provides for a maximum
of 516,800 shares of common stock of the Company to be granted over ten years
from the date the Plan was adopted.
 
     Incentive stock options may be issued under the Plan at an option price not
less than the fair market value at the date of grant as determined by the Board
of Directors (110% of fair market value in the case of stockholders having
ownership in excess of 10%). Non-qualified stock options may be issued under the
Plan at an option price as determined by the Board of Directors at the date of
the grant.
 
     The incentive stock options are exercisable for a period not to exceed ten
years from the date of grant (five years in the case of incentive stock options
for stockholders having ownership in excess of 10%). The non-qualified options
are exercisable in accordance with the terms agreed for each option granted.
 
     Stock option activity is summarized as follows:

     The Company has gross deferred tax assets at May 31, 1995 of approximately
$401,000, net of a valuation reserve of $156,500 described below. The Company
has gross deferred tax liabilities at May 31, 1995 of approximately $8,000.
 
     Deferred income taxes reflect the effect of temporary differences between
the tax basis of assets and liabilities and the reported amounts of assets and
liabilities for financial reporting purposes net of any valuation allowances.
The components of deferred taxes consist primarily of temporary differences
arising from accrued expenses and deferred revenue that are deductible or
taxable in future tax reporting periods.
 
     The following is a reconciliation between the amount of reported income tax
expense and the amount computed using the statutory rate of 35% for fiscal 1995:

     Symmetrix Europe reported a net operating loss of approximately $447,000
which expires in the year 2000. The Company has recorded a full valuation
allowance at May 31, 1995 on the deferred tax asset, and therefore no benefit
for the loss carryforward has been recognized since realization of these future
benefits is not sufficiently assured.

     The Company entered into a contract with Olympic Manufacturing Group, Inc.
("Olympic"), in which the Company has an investment as of May 31, 1995. The

8. LEASES
 
     The Company leases office space under a noncancelable operating lease. The
Company amended the lease on January 11, 1994 for additional space. The lease
expired in 1995 and the Company exercised an option to extend the lease for two
years. The lease requires the Company to pay a proportionate share of the
building operating costs and real estate taxes that exceed a base amount as
additional rent. Rental expense under the operating leases was approximately
$734,300 for the year ended May 31, 1995. Future minimum lease payments under
the operating lease as of May 31, 1995 consist of approximately $778,000 due in
fiscal year 1996 and approximately $713,000 due in fiscal year 1997.
Additionally, the Company leases certain office and computer equipment under
capital leases. At May 31, 1995, capital lease obligations, including interest,
are $17,591.

                         NOTES TO FINANCIAL STATEMENTS
 
1. BASIS OF PRESENTATION
 
     SiGMA Consulting, LLC ("SiGMA" or the "Company") offers consulting services
focusing on change management and helping organizations improve core business
processes, including product development, manufacturing and distribution, sales,
and enterprise management. SiGMA primarily offers its services to the
manufacturing, high technology, entertainment, and transportation industries.
 
     Effective January 1, 1996, SiGMA was formed as a successor company to SiGMA
Consulting, Inc. The results of operations for the twelve month period ended
December 31, 1995 are for SiGMA Consulting, Inc. Upon formation, the assets and
liabilities previously held by SiGMA Consulting, Inc. were assumed by SiGMA.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the reported
period. Actual results could differ from those estimates.
 
Revenue Recognition
 
     The Company primarily derives its revenues from consulting services under
time and materials, capped-fee and fixed-price billing arrangements. Under time
and material arrangements, revenues are recognized as the services are provided.
Revenues on fixed-price and capped-fee contracts are recognized using the
percentage of completion method of accounting and are adjusted monthly for the
cumulative impact of any revision in estimates. The Company determines the
percentage of completion of its contracts by comparing costs incurred to date to
total estimated costs. Contract costs include all direct labor and expenses
related to the contract performance. Costs and estimated earnings in excess of
billings represents revenue recognized in excess of amounts billed from
fixed-price contracts. Deferred revenue represents billings in excess of
revenues recognized. Net revenues exclude reimbursable expenses charged to
clients.
 
Property and Equipment
 
     Property and equipment are stated at cost. Depreciation has been provided
using the straight-line method over the following estimated useful lives:
 
<TABLE>
<S>                                                <C>
Furniture and fixtures...........................   5-7 years
Equipment........................................   3-5 years
</TABLE>
 
     Leasehold improvements are amortized over the lesser of the lease term or
the useful life of the property, whichever is shorter.
 
Financial Instruments
 
     The carrying value of financial instruments such as accounts receivable,
accounts payable and accrued expenses and notes payable to bank approximate
their fair values based on the short-term maturities of these instruments.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
Concentration of Credit Risk
 
     The Company provides its services to customers in diversified industries,
primarily in the United States. The Company performs ongoing credit evaluations
of its customers and generally does not require collateral. The Company
maintains reserves for potential credit losses and such losses have been within
management's expectations. Revenues from three significant customers accounted
for 62%, 49% and 49% of net revenues for the years ended December 31, 1995, 1996
and 1997, respectively. Two customers accounted for 31% and 52% of total
receivables, as of December 31, 1996 and 1997, respectively.
 
Income Taxes
 
     The Company is treated as a partnership for federal and state income tax
purposes. Therefore, all items of income, expense, and tax credit are passed
through to the individual unit holders. Accordingly, no provision for income
taxes is required. No tax provision was recorded for the year ended December 31,
1995 for SiGMA Consulting, Inc. as the Company was in a net loss position.
 
3. PROPERTY AND EQUIPMENT
 
     Property and equipment consists of the following:

                     THE PLANNING TECHNOLOGIES GROUP, INC.
 
                         NOTES TO FINANCIAL STATEMENTS
 
1. THE COMPANY
 
     The Planning Technologies Group, Inc. ("PTG" or the "Company") offers
strategy formulation, strategic planning process design, and business process
assessment and redesign services. PTG primarily offers its services to the
health care, insurance, financial services, consumer products, manufacturing and
high technology industries.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
Reclassification
 
     Certain prior year amounts have been reclassified to conform to the current
year presentation.
 
Interim Financial Statements (Unaudited)
 
     The balance sheet at March 31, 1998 and the statements of income and
retained earnings, and cash flows for the three months ended March 31, 1997 and
1998 are unaudited, and, in the opinion of management, include all adjustments,
consisting only of normal recurring adjustments, necessary for a fair
presentation of the Company's consolidated financial position, results of
operations and cash flows.
 
Use of Estimates
 
     The preparation of financial statements, in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the reported
period. Actual results could differ from those estimates.
 
Revenue Recognition
 
     The Company derives its revenues from consulting services under time and
materials billing arrangements. Revenues are recognized as the services are
provided. Deferred revenue represents billings in excess of revenues recognized.
Net revenues exclude reimbursable expenses charged to clients.
 
Cash and Cash Equivalents
 
     The Company considers all highly liquid investments and other short-term
investments with a maturity of three months or less when purchased to be cash
equivalents. Cash equivalents are stated at cost which approximates market
value.
 
Property and Equipment
 
     Property and equipment are stated at cost. Depreciation is provided using
the straight-line method over the following estimated useful lives of the assets
as follows:
 
<TABLE>
<S>                                                   <C>
Equipment...........................................  5 years
Furniture and fixtures..............................  7 years
</TABLE>
 
     Leasehold improvements are amortized over the lesser of the lease term or
the useful life of the property, whichever is shorter.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
Financial Instruments
 
     The carrying value of financial instruments such as cash equivalents,
accounts receivable, accounts payable and accrued expenses approximate their
fair values based on the short-term maturities of these instruments.
 
Concentration of Significant Customers
 
     The Company provides its services to customers in diversified industries,
primarily in the United States. The Company performs ongoing credit evaluations
of its customers and generally does not require collateral. Sales to three
significant customers accounted for 32%, 29% and 20%, respectively, of net
revenues for the year ended December 31, 1997.
 
Income Taxes
 
     The Company has elected to be taxed under the provisions of Subchapter "S"
of the Internal Revenue Code. Accordingly, no provision for federal income taxes
has been provided in the financial statements as all income of the Company is
taxed directly to the shareholders.

To the Partners of
Sibson & Company, L.P.
 
     We have audited the accompanying consolidated balance sheets of Sibson &
Company, L.P. and Subsidiaries as of December 31, 1996 and 1997 and the related
consolidated statements of operations and partners' capital and cash flows for
each of the three years in the period ended December 31, 1997. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Sibson &
Company, L.P. and Subsidiaries as at December 31, 1996 and 1997, and the results
of their operations and their cash flows for each of the three years in the

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. THE COMPANY
 
     Sibson & Company, L.P. (the "Company"), a limited partnership, provides
human capital consulting services offering human resource strategies,
outsourcing assessments, organizational designs, rewards/incentives programs,
performance management processes and systems, and executive coaching services.
The Company also serves sales and marketing organizations with sales strategy,
selling process, sales channel and selling effectiveness consulting.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
Principles of Consolidation
 
     The consolidated financial statements include the accounts of Sibson &
Company, L.P. and its 99% owned subsidiary, Sibson Europe, LLC and its 100%
owned subsidiary Sibson UK Limited. All significant intercompany accounts and
transactions have been eliminated in consolidation.
 
Interim Financial Statements (Unaudited)
 
     The balance sheet at June 30, 1998, and the statements of operations and
partners' capital, and cash flows for the six months ended June 30, 1997 and
1998 are unaudited, and, in the opinion of management, include all adjustments,
consisting only of normal recurring adjustments, necessary for a fair
presentation of the Company's consolidated financial position, results of
operations and cash flows.
 
Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the reported
period. Actual results could differ from those estimates.
 
Revenue Recognition
 
     The Company derives its revenues from consulting services primarily under
time and materials billing arrangements. Under time and materials arrangements,
revenues are recognized as the services are provided. Revenues exclude
reimbursable expenses charged to clients.
 
Cash and Cash Equivalents
 
     The Company considers all short-term investments with an original maturity
of three months or less when purchased to be cash equivalents.
 
Fixed Assets
 
     Fixed assets are stated at cost. Depreciation is provided using the
accelerated methods over estimated useful lives of five to seven years.
Leasehold improvements are amortized over the lesser of the lease term or the
estimated life of the improvements, whichever is shorter.
 
Financial Instruments
 
     The carrying value of financial instruments such as cash equivalents,
accounts receivable, accounts payable and accrued expenses approximate their
fair values based on the short-term maturities of these instruments. The
carrying value of long-term debt approximates its fair value based on references
to similar instruments.

Post-retirement Healthcare Benefit
 
     The Company presently provides a post-retirement healthcare benefits plan
which provides for 75% of the annual cost of medical coverage for a retiree with
at least 15 years of service and who is between 50 and 64 years of age. Coverage
ceases once the retiree reaches age 65.
 
     Effective January 1, 1995, the Company adopted SFAS No. 106, Employers
Accounting for Post-retirement Benefits Other Than Pensions ("SFAS No. 106").
This statement requires the Company to accrue, during the employee's years of
service, the expected cost of providing benefits. The cost of providing these
benefits was previously recognized in the period in which the benefits were
paid.
 
     The Company adopted SFAS No. 106 on a prospective basis. The net transition
obligation represents the difference between the Company's January 1, 1995
accrued post-retirement healthcare costs prior to the adoption of SFAS No. 106
and the unfunded liability for these costs as of that date. The Company does not
fund these costs. The net transition liability at January 1, 1995 was $684,766
and will be amortized over 20 years.
 
     The components of net periodic post-retirement healthcare benefit cost are
as follows:

     The assumed healthcare cost trend rate used in measuring the accumulated
post-retirement obligation was 7% with subsequent annual decrements of 0.15% to
an ultimate trend rate of 3.5%. A 1.0% increase in the assumed healthcare cost
trend rate for each year would increase the accumulated post-retirement
healthcare benefit obligation by approximately 11% and the net post-retirement
cost by approximately 15%. The discount rate used in determining the accumulated
post-retirement healthcare benefit liability was 7%.

To the Directors of
Sibson Canada, Inc.
 
     We have audited the balance sheet of Sibson Canada, Inc. as at December 31,
1997 and the statements of operations and retained earnings and changes in
financial position for the year then ended. These financial statements are the
responsibility of the company's management. Our responsibility is to express an

     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform an audit to obtain
reasonable assurance whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by

     In our opinion, these financial statements present fairly, in all material
respects, the financial position of the company as at December 31, 1997 and the
results of its operations and changes in its financial position for the year

2. SIGNIFICANT ACCOUNTING POLICIES
 
Basis of Presentation
 
     The financial statements have been prepared by management in accordance
with accounting principles generally accepted in Canada. See Note 10 for
differences between these principles and those generally accepted in the United
States. All amounts in the financial statements are expressed in Canadian
dollars.
 
Interim Financial Statements (Unaudited)
 
     The balance sheet at June 30, 1998, and the statements of operations and
retained earnings and changes in financial position for the six months ended
June 30, 1998 and 1997 are unaudited, and, in the opinion of management, include
all adjustments, consisting only of normal recurring adjustments, necessary for
a fair presentation of the Company's financial position, results of operations
and cash flows.
 
Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the reported
period. Actual results could differ from those estimates.
 
Revenue Recognition
 
     The company derives its revenues from consulting services under time and
materials billing arrangements. Revenues are recognized as services are
provided. Deferred income relates to funds received from clients for future
projects.
 
Depreciation
 
     Rates and bases of depreciation applied to write-off the cost less
estimated salvage value of property and equipment over their estimated lives are
as follows:

10. DIFFERENCES BETWEEN CANADIAN AND UNITED STATES GENERALLY ACCEPTED ACCOUNTING
PRINCIPLES
 
     The accounting principles utilized in the preparation of these financial
statements conform in all material respects with those generally accepted in the
United States ("US GAAP"), except as indicated below.
 
     The statement of changes in financial position included herein was prepared
in accordance with Canadian generally accepted accounting principles. Under US
GAAP, the bank indebtedness position would be reported as a financing item
rather than being included in the cash position. The 1997 statement of changes
in financial position would disclose a decrease in financing of $177,391, and
cash at the beginning of the year at $0.
 
11. SUBSEQUENT EVENTS
 
     On August 17, 1998, the Company and one of its corporate shareholders
continued as Nova Scotia corporations. Subsequently, the Company, the corporate
shareholder and a newly incorporated unlimited liability company, were
amalgamated under the laws of Nova Scotia and continued operating as Sibson
Canada Co.
 
     Effective August 31, 1998, all of the Company's Shareholders sold all of
their stock to Nextera Enterprises, L.L.C. in exchange for cash of US$2,611,000
and 197,813 Exchangeable Preference Shares. The Exchangeable Preference Shares
are exchangeable at any time by the holders thereof for Class A Common Stock of
Nextera Enterprises, L.L.C.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Under Section 145 of the Delaware General Corporation Law, the Company has
broad powers to indemnify its directors and officers against liabilities they
may incur in such capacities, including liabilities under the Securities Act.
 
     The Company's Certificate of Incorporation and Bylaws provide that the
Company will indemnify its directors and officers to the fullest extent
permitted by Delaware law. Delaware law permits, but does not require, a
corporation to indemnify officers, directors, employees or agents and expressly
provides that the indemnification provided for under Delaware law shall not be
deemed exclusive of any indemnification right under any bylaw, vote of
stockholders or disinterested directors, or otherwise. Delaware law permits
indemnification against expenses and certain other liabilities arising out of
legal actions brought or threatened against such persons for their conduct on
behalf of the Company, provided that each such person acted in good faith and in
a manner that he or she reasonably believed was in or not opposed to the
Company's best interests and in the case of a criminal proceeding, had no
reasonable cause to believe his or her conduct was unlawful. Delaware law does
not allow indemnification of directors in the case of an action by or in the
right of the Company (including stockholder derivative suits) unless the
directors successfully defend the action or indemnification is ordered by the
court.
 
     The Company is a party to indemnification agreements with each of its
directors and officers. In addition, the form of Underwriting Agreement filed as
Exhibit 1.1 hereto provides for the indemnification of the Company and its
directors and officers against certain liabilities, including liabilities under
the Securities Act.
 
     The Company maintains directors' and officers' liability insurance covering
its executive officers and directors. The policies have limits of up to
$          in the aggregate, subject to retentions of up to $          in the
aggregate.

ITEM 17. UNDERTAKINGS.
 
     The undersigned registrant hereby undertakes to provide to the underwriters
at the Closing specified in the underwriting agreements, certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions or otherwise, the Company has
been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Company of expenses incurred or paid
by a director, officer or controlling person of the Company in the successful
defense of any action, suit or proceeding) is asserted by such director, officer
or controlling person in connection with the securities being registered, the
Company will, unless in the opinion of its counsel the matter has been settled
by controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.

     The undersigned registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities
     Act, the information omitted from the form of prospectus filed as part of
     this Registration Statement in reliance upon Rule 430A and contained in a
     form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     Registration Statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of prospectus shall
     be deemed to be a new registration statement relating to the securities
     offered therein, and the Offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

                                  ARTICLE THREE
                                     PURPOSE

          The nature of the business and of the purposes to be conducted and
promoted by the Corporation shall be to engage in any lawful act or activity for
which corporations may be organized under the General Corporation Law. The
Corporation shall possess and exercise all the powers and privileges granted by
the General Corporation Law, by any other law or by this Amended and Restated
Certificate of



<PAGE>   2

Incorporation, together with any powers incidental thereto as far as such powers
and privileges are necessary or convenient to the conduct, promotion or
attainment of the purposes of the Corporation.


                                  ARTICLE FOUR
                                CAPITAL STRUCTURE

          The total number of shares of capital stock which the Corporation
shall have the authority to issue is [64,300,000] shares, consisting of three
classes of capital stock:

               (a) [50,000,000] shares of Class A Common Stock, par value
          [$0.001] per share (the "Class A Common Stock");

               (b) [4,300,000] shares of Class B Common Stock, par value
          [$0.001] per share (the "Class B Common Stock," and together with the
          Class A Common Stock, the "Common Stock"); and

               (c) [10,000,000] shares of Preferred Stock, par value [$0.001]
         per share (the "Preferred Stock").


                                  ARTICLE FIVE
                                  COMMON STOCK

          5.1 Identical Rights. Except as otherwise set forth in this ARTICLE
FIVE, the rights and privileges of the Common Stock shall be identical,
including, without limitation, the right to participate ratably in dividends and
other distributions (including distributions upon liquidation, dissolution or
other winding up of the Corporation), payable in cash, stock or property, except
that in the case of dividends or distributions payable in shares of a class of
Common Stock, only shares of Class A Common Stock may be distributed with
respect to Class A Common Stock and only shares of Class B Common Stock may be
distributed with respect to Class B Common Stock, and the number of shares of
Common Stock payable per share will be equal for each class. In addition,
neither the shares of Class A Common Stock nor the shares of Class B Common
Stock may be subdivided, consolidated, reclassified or otherwise changed unless
concurrently the shares of the other class of Common Stock are subdivided,
consolidated, reclassified or otherwise changed in the same proportion and the
same manner. The Corporation may not make any dividend or distribution with
respect to any class of Common Stock unless at the same time the Corporation
makes a ratable dividend or distribution with respect to each outstanding share
of Common Stock regardless of class. The rights of holders of Class A Common
Stock and Class B Common Stock are subject to the rights of holders of shares of
any series of Preferred Stock that the Corporation may designate and issue from
time to time.

          5.2 Voting Rights. The holders of the Common Stock shall vote as a
single class on all matters submitted to a vote of the stockholders to which the
holders of Common Stock are entitled to vote, except as may be required by
Delaware law or as otherwise expressly specified in this Amended and Restated
Certificate of Incorporation. Each share of Class A Common Stock shall be
entitled to one vote and each share of Class B Common Stock shall be entitled to
ten votes. The Corporation, by action of its Board of Directors and the
affirmative vote of the holders of a majority of the voting power of the capital
stock of the Corporation entitled to vote, may increase or decrease the number
of authorized shares of Common Stock or Preferred Stock of the Corporation (but
not below the number 


                                       2
<PAGE>   3
of shares of Common Stock or Preferred Stock, respectively, then outstanding)
irrespective of the provisions of Section 242(b)(2) of the General Corporation
Law; provided, however, that any increase or decrease the number of authorized
shares of Class B Common Stock shall in addition to the foregoing, require the
affirmative vote of the holders of a majority of the voting power of the Class B
Common Stock, voting as a separate class.

          5.3 Conversion Rights.

               (a) Voluntary Conversion. Each share of Class B Common Stock is
          convertible into one fully paid and non-assessable share of Class A
          Common Stock at any time at the option of the holder. In order to
          exercise the conversion privilege, the holder of any shares of Class B
          Common Stock to be converted shall present and surrender the
          certificate or certificates representing such shares during usual
          business hours at the principal executive offices of the Corporation,
          or if any agent for the registration of transfer of shares of Class B
          Common Stock is then duly appointed and acting (said agent being
          hereinafter called the "Transfer Agent"), then at the office of the
          Transfer Agent, accompanied by written notice that the holder elects
          to convert the shares of Class B Common Stock represented by such
          certificate or certificates, to the extent specified in such notice.
          Such notice shall also state the name or names (with addresses) in
          which the certificate or certificates for shares of Class A Common
          Stock which shall be issuable on such conversion shall be issued. If
          required by the Corporation, any certificate for shares of Class B
          Common Stock surrendered for conversion shall be accompanied by
          instruments of transfer, in form satisfactory to the Corporation and
          the Transfer Agent, duly executed by the holder of such shares or his
          or her duly authorized representative. As promptly as practicable
          after the receipt of such notice and the surrender of the certificate
          or certificates representing such shares of Class B Common Stock as
          aforesaid, the Corporation shall issue and deliver at such office to
          such holder, or on his or her written order, a certificate or
          certificates for the number of full shares of Class A Common Stock
          issuable upon the conversion of such shares. Each conversion of shares
          of Class B Common Stock shall be deemed to have been effected on the
          date on which such notice shall have been received by the Corporation
          or the Transfer Agent, as applicable, and the certificate or
          certificates representing such shares shall have been surrendered
          (subject to receipt by the Corporation or the Transfer Agent, as
          applicable, within thirty (30) days thereafter of any required
          instruments of transfer as aforesaid), and the person or persons in
          whose name or names any certificate or certificates for shares of
          Class A Common Stock shall be issuable upon such conversion shall be
          deemed to have become on said date the holder or holders of record of
          the shares represented thereby.

               (b) Automatic Conversion.

                    (i) Each share of Class B Common Stock shall convert
          automatically into one fully paid and non-assessable share of Class A
          Common Stock immediately prior to its sale, assignment, pledge, gift
          or other transfer (an "Assignment" or to "Assign"), other than (a) to
          a Controlled Affiliate of the transferor; or (b) pursuant to a
          Qualified Transfer (as defined below). For purposes of this Section
          5.3(b), the term "Controlled Affiliate" shall mean, with respect to a
          transferor, any individual or entity that is controlled directly or
          indirectly (by ownership of voting securities, contract or otherwise)
          by such transferor. "Qualified Transfer" means (i) any transfer of
          shares of Class B Common Stock by will or pursuant to the laws of
          descent and distribution to any member or members of a stockholder's
          Family, (ii) any transfer of shares of Class B Common Stock by a
          stockholder to a domestic trust created for the sole benefit of one or
          more of the stockholder or any member or members of the stockholder's
          Family, (iii) any transfer of shares of 



                                       3
<PAGE>   4
          Class B Common Stock from a trust described in clause (ii) above to
          the stockholder (or former stockholder) who transferred shares of
          Class B Common Stock to such trust, (iv) any transfer to a domestic
          limited partnership or a domestic limited liability company if there
          are no partners or members of such limited partnership or limited
          liability company other than a stockholder and members of a
          stockholder's Family; (v) any transfer of Class B Common Stock from a
          limited partnership or limited liability company described in clause
          (iv) above to a stockholder (or former stockholder) who transferred
          Class B Common Stock to such limited partnership or limited liability
          company; and (vi) any transfer of shares of Class B Common Stock from
          one holder of Class B Common Stock to another holder of Class B Common
          Stock as of August 31, 1998. "Family" means a person's spouse, lineal
          descendants, parents, siblings, and lineal descendants of siblings.
          Any such relationship by legal adoption shall be included.

                    (ii) Upon any Assignment of Class B Common Stock by
          Knowledge Enterprises, Inc. ("KE"), other than to a Controlled
          Affiliate or pursuant to a Qualified Transfer, a proportionate amount
          of the Class B Common Stock held by the other holders of Class B
          Common Stock will also automatically convert into fully paid and
          non-assessable shares of Class A Common Stock. For example, if KE
          Assigns 25% of its Class B Common Stock to a third party who is not a
          Controlled Affiliate and not pursuant to a Qualified Transfer, then
          those shares of Class B Common Stock will automatically convert into
          Class A Common Stock on a one to one basis and 25% of the Class B
          Common Stock held by each other holder of Class B Common Stock will
          automatically convert into Class A Common Stock on a one to one basis.

                    (iii) In the event that a group comprised of one or more of
          Michael R. Milken, Lawrence J. Ellison or Lowell J. Milken ceases to
          control, directly or indirectly (through the ownership of voting
          securities, contract or otherwise), KE or any other Person that owns
          any or all of the shares of Class B Common Stock owned by KE on the
          date hereof, then all Class B Common Stock shall automatically convert
          into fully paid and non-assessable shares of Class A Common Stock.

               Notwithstanding the foregoing, any holder of Class B Common Stock
          may pledge his shares of Class B Common Stock to a financial
          institution (the "Pledgee") pursuant to a bona fide pledge of such
          shares as collateral security for indebtedness due to the Pledgee,
          and, if the Pledgee forecloses or takes similar action, such pledged
          shares of Class B Common Stock shall be converted automatically into
          fully paid and non-assessable shares of Class A Common Stock
          immediately prior to such foreclosure or similar action.

               (c) Unconverted Shares. If less than all of the shares of Class B
          Common Stock evidenced by a certificate or certificates surrendered to
          the Corporation (in accordance with such procedures as the Board of
          Directors may determine) are converted, the Corporation shall execute
          and deliver to or upon the written order of the holder of such
          certificate or certificates a new certificate or certificates
          evidencing the number of shares of Class B Common Stock which are not
          converted without charge to the holder.

               (d) Converted Shares. Any share of Class B Common Stock converted
          pursuant to this Article Five shall thereupon be retired and may not
          be reissued.

               (e) Class A Common Stock. The Class A Common Stock has no
          conversion rights.



                                       4
<PAGE>   5

          5.4 Reservation. The Corporation hereby reserves, and shall at all
times reserve and keep available, out of its authorized and unissued shares of
Class A Common Stock, for the purposes of effecting conversions, such number of
duly authorized shares of Class A Common Stock as shall from time to time be
sufficient to effect the conversion of all outstanding shares of Class B Common
Stock. The Corporation covenants that all the shares of Class A Common Stock so
issuable shall, when so issued, be duly and validly issued, fully paid and
non-assessable. The Corporation shall take all such action as may be necessary
to assure that all such shares of Class A Common Stock may be so issued without
violation of any applicable law or regulation.

          5.5 Merger. Upon the merger or consolidation of the Corporation,
holders of each class of Common Stock will be entitled to receive equal per
share payments or distributions, except that in any transaction in which shares
of capital stock are distributed, such shares may differ to the extent that the
Class A Common Stock and the Class B Common Stock differ as provided in this
Amended and Restated Certificate of Incorporation.

          5.6 Liquidation. Upon any dissolution or liquidation of the
Corporation, the holders of the Class A Common Stock and Class B Common Stock
will be entitled to receive ratably all assets of the Corporation available for
distribution to stockholders, subject to any preferential rights of any then
outstanding shares of Preferred Stock.


                                   ARTICLE SIX
                                 PREFERRED STOCK

          Shares of Preferred Stock may be issued from time to time in one or
more series, each of such series to have such terms as stated in the resolution
or resolutions providing for the establishment of such series adopted by the
Board of Directors of the Corporation as hereinafter provided. Except as
otherwise expressly stated in the resolution or resolutions providing for the
establishment of a series of Preferred Stock, any shares of Preferred Stock
which may be redeemed, purchased or acquired by the Corporation may be reissued
except as otherwise expressly provided by law.

          Authority is hereby expressly granted to the Board of Directors of the
Corporation to issue, from time to time, shares of Preferred Stock in one or
more series, and, in connection with the establishment of any such series by
resolution or resolutions, to determine and fix such voting powers, full or
limited, or no voting powers, and such other powers, designations, preferences
and relative, participating, optional and other special rights, and the
qualifications, limitations and restrictions thereof, if any including, without
limitation, dividend rights, conversion rights, redemption and sinking fund
privileges, and liquidation preferences, as shall be stated in such resolution
or resolutions, all to the fullest extent permitted by the General Corporation
Law. Without limiting the generality of the foregoing, the resolution or
resolutions providing for the establishment of any series of Preferred Stock
may, to the extent permitted by law, provide that such series shall be superior
to, rank equally with or be junior to the Preferred Stock of any other series.
Except as otherwise expressly provided in the resolution or resolutions
providing for the establishment of any series of Preferred Stock, no vote of the
holders of shares of Preferred Stock or Common Stock shall be a prerequisite to
the issuance of any shares of any series of the Preferred Stock authorized by
and complying with the conditions of this Amended and Restated Certificate of
Incorporation.

                                  ARTICLE SEVEN
                               BOARD OF DIRECTORS

          7.1 Number of Directors. The business and affairs of the Corporation
shall be managed by or under the direction of a Board of Directors consisting of
not less than seven nor more than thirteen directors, the exact number of
directors to be determined from time to time solely by resolution adopted by the
affirmative vote of a majority of the entire Board of Directors.

          7.2 Removal. No director (other than directors elected by one or more
series of Preferred Stock) may be removed from office by the stockholders except
for cause and, in addition to any other vote required by law, upon the
affirmative vote of the holders of not less than 66 2/3% of the total voting
power of all outstanding securities of the Corporation then entitled to vote
generally in the election of directors, voting together as a single class.

          7.3 Limitation of Liability. No director of the Corporation shall be
personally liable to the Corporation or its stockholders for monetary damages
for breach of fiduciary duty as a director; provided that this provision shall
not eliminate or limit the liability of a director (a) for any breach of the
director's duty of loyalty to the Corporation or its stockholders, (b) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (c) under section 174 of the General Corporation Law
or (d) for any transaction from which the director derived any improper personal
benefits.

         If the General Corporation Law is amended after approval by the
stockholders of this ARTICLE SEVEN to authorize corporate action further
eliminating or limiting the personal liability of directors, then the liability
of a director of the Corporation shall be eliminated or limited to the fullest
extent permitted by the General Corporation Law, as so amended. No amendment to
or repeal of this provision shall apply to or have any effect on the liability
or alleged liability of any director of the Corporation for or with respect to
any acts or omissions of such director occurring prior to such amendment.

                                  ARTICLE EIGHT
                              CORPORATE GOVERNANCE

          The following provisions are inserted for the management of the
business and the conduct of the affairs of the Corporation and for the further
definition of the powers of the Corporation and its directors and stockholders:

               1. The Board of Directors shall have the power to adopt, amend or
          repeal the by-laws of the Corporation.

               2. The stockholders may adopt, amend, alter, repeal or rescind
          the by-laws of the Corporation only with, in addition to any other
          vote required by law, the affirmative vote of the holders of not less
          than 66 2/3% of the total voting power of all outstanding securities
          of the Corporation then entitled to vote generally in the election of
          directors, voting together as a single class.

               3. Elections of directors need not be by written ballot unless
          the by-laws of the Corporation so provide.

<PAGE>   7

               4. Any action required or permitted to be taken at any annual or
          special meeting of stockholders may be taken only upon the vote of
          stockholders at an annual or special meeting duly noticed and called
          in accordance with the General Corporation Law, and may not be taken
          by written consent of stockholders without a meeting.

               5. Special meetings of stockholders may be called by the Board of
          Directors, the Chairman of the Board of Directors or the President of
          the Corporation and may not be called by any other person.
          Notwithstanding the foregoing, whenever holders of one or more series
          of Preferred Stock shall have the right, voting separately as a
          series, to elect directors, such holders may call special meetings of
          such holders pursuant to the certificate of designation for such
          series.


                                  ARTICLE NINE
                               STOCKHOLDER LOCK-UP

          Until the date that is 180 days after the date of the final prospectus
relating to the Corporation's initial public offering of equity securities (the
"Initial Public Offering"), each holder of shares of Common Stock, other than
shares of Common Stock acquired in such Initial Public Offering, hereby:

               (a) agrees not to (x) offer, pledge, sell, contract to sell, sell
          any option or contract to purchase, purchase any option or contract to
          sell, grant any option, right or warrant to purchase, or otherwise
          transfer or dispose of, directly or indirectly, any shares of Common
          Stock or any securities convertible into or exercisable or
          exchangeable for Common Stock (including, without limitation, shares
          of Common Stock or securities convertible into or exercisable or 
          exchangeable for Common Stock which may be deemed to be beneficially
          owned by such holder in accordance with the rules and regulations of
          the Securities and Exchange Commission) or (y) enter into any swap or
          other arrangement that transfers all or a portion of the economic
          consequences associated with the ownership of Common Stock (regardless
          of whether any of the transactions described in clause (x) or (y) is
          to be settled by the delivery of Common Stock, or such other
          securities, in cash or otherwise), without the prior written consent
          of the lead managing underwriter of such Initial Public Offering;

               (b) agrees not to make any demand for, or exercise any right with
          respect to, the registration of any shares of Common Stock or any
          securities convertible into or exercisable or exchangeable for Common
          Stock, without the prior written consent of the lead managing
          underwriter of such Initial Public Offering; and

               (c) authorizes the Corporation to cause the transfer agent to
          decline to transfer and/or to note stop transfer restrictions on the
          transfer books and records of the Corporation with respect to any

                  Section 2. OTHER OFFICES. The corporation may also have
offices at such other places both within and without the State of Delaware as
the Board of Directors may from time to time determine or the business of the
corporation may require.
                                   ARTICLE II

                            MEETINGS OF STOCKHOLDERS

                  Section 1. PLACE OF MEETINGS. Meetings of stockholders shall
be held at any place within or outside the State of Delaware designated by the
Board of Directors. In the absence of any such designation, stockholders'
meetings shall be held at the principal executive office of the corporation.

                  Section 2. ANNUAL MEETING OF STOCKHOLDERS. The annual meeting
of stockholders shall be held each year on a date and a time designated by the
Board of Directors.

                  Section 3. QUORUM; ADJOURNED MEETINGS AND NOTICE THEREOF. A
majority of the voting power of the shares of capital stock of the corporation
issued and outstanding and entitled to vote at any meeting of stockholders, the
holders of which are present in person or represented by proxy, shall constitute
a quorum for the transaction of business except as otherwise provided by law, by
the Amended and Restated Certificate of Incorporation, or by these Bylaws. A
quorum, once established, shall not be broken by the withdrawal of enough votes
to leave less than a quorum and the votes present may continue to transact
business until adjournment. If, however, such quorum shall not be present or



                                       1
<PAGE>   5

represented at any meeting of the stockholders, a majority of the voting power
of the shares of capital stock represented in person or by proxy at such meeting
may adjourn the meeting from time to time, without notice other than
announcement at the meeting of the time and place of the adjourned meeting,
until a quorum shall be present or represented. At such adjourned meeting at

adjournment is for more than thirty days, or if after the adjournment a new
record date is fixed for the adjourned meeting, a notice of the adjourned
meeting shall be given to each stockholder of record entitled to vote thereat.

                  Section 4. VOTING. When a quorum is present at any meeting, in
all matters other than the election of directors, the vote of the holders of
stock representing a majority of the voting power present in person or
represented by proxy shall decide any question brought before such meeting,
unless the question is one upon which by express provision of the Amended and
Restated Certificate of Incorporation, or these Bylaws, or any rule, regulation
or statutory provision applicable to the corporation, a different vote is
required in which case such express provision shall govern and control the
decision of such question. Directors shall be elected by a plurality of the
votes of the shares present in person or represented by proxy at the meeting and
entitled to vote on the election of directors.

                  Section 5. PROXIES. At each meeting of the stockholders, each
stockholder having the right to vote may vote in person or may authorize another

writing subscribed by such stockholder and bearing a date not more than three
years prior to said meeting, unless said instrument provides for a longer
period. All proxies must be filed with the Secretary of the corporation at the
beginning of each meeting in order to be counted in any vote at the meeting.

                  Section 6. SPECIAL MEETINGS. Special meetings of the
stockholders, for any purpose, or purposes, unless otherwise prescribed by
statute or by the Amended and Restated Certificate of Incorporation, may be

President or the Secretary at the request in writing of the Board of Directors.
Business transacted at any special meeting of stockholders shall be limited to
the purposes stated in the notice.

writing to the Secretary of the corporation and such other business must

stockholder's notice shall be delivered to the Secretary at the principal
executive offices of the corporation not later than the close of business on the
60th day nor earlier than the close of business on the 90th day prior to the
first anniversary of the preceding year's annual meeting; provided, however,
that in the event that the date of the annual meeting is not within 30 days
before or after such anniversary date, notice by the stockholder to be timely
must be so delivered not earlier than the close of business on the 90th day
prior to such annual meeting and not later than the close of business on the
later of the 60th day prior to such annual meeting or the 10th day following the
earlier of (i) the day on which notice of the meeting was mailed or (ii) the
date public announcement of the date of such meeting is first made by the

annual meeting commence a new time period for the giving of a stockholder's
notice as described above. Such stockholder's notice shall set forth (a) as to
each person whom the stockholder proposes to nominate for election or
re-election as a director all information relating to such person that is
required to be disclosed in solicitations of proxies for election of directors
in an election contest, or is otherwise required, in each case pursuant to

<PAGE>   7

Exchange Act of 1934, as amended (the "Exchange Act"), and Rule 14A-11
thereunder (including such person's written consent to being named in the proxy
statement as a nominee and to serving as a director if elected); (b) as to any
other business that the stockholder proposes to bring before the meeting, a
brief description of the business desired to be brought before the meeting, the
reasons for conducting such business at the meeting and any material interest in
such business of such stockholder and the beneficial owner, if any, on whose
behalf the nomination or proposal is made; and (c) as to the stockholder giving
the notice and the beneficial owner, if any, on whose behalf the nomination or
proposal is made (i) the name and address of such stockholder and of such
beneficial owner, as they appear on the corporation's books, and (ii) the class
and number of shares of the corporation which are owned beneficially and of
record by such stockholder and such beneficial owner.

                  Section 8. MAINTENANCE AND INSPECTION OF STOCKHOLDER LIST. The
officer who has charge of the stock ledger of the corporation shall prepare and
make, at least ten days before every meeting of stockholders, a complete list of
the stockholders entitled to vote at the meeting, arranged in alphabetical
order, and showing the address of each stockholder and the number of shares
registered in the name of each stockholder. Such list shall be open to the
examination of any stockholder, for any purpose germane to the meeting, during
ordinary business hours, for a period of at least ten days prior to the meeting,
either at a place within the city where the meeting is to be held, which place
shall be specified in the notice of the meeting, or, if not so specified, at the
place where the meeting is to be held. The list shall also be produced and kept
at the time and place of the meeting during the whole time thereof, and may be

                  Section 1.  THE NUMBER OF DIRECTORS.

                  The number of directors (other than directors elected by one
or more series of Preferred Stock) which shall constitute the entire Board shall
be not less than seven nor more than thirteen directors, the exact number of
directors to be determined from time to time solely by resolution adopted by the
affirmative vote of a majority of the directors. The directors need not be
stockholders. The directors shall be elected at the annual meeting of the
stockholders, except as provided in Section 2 of this Article, and each director
elected shall hold office until his/her successor is duly elected and qualified.

                  Section 2. VACANCIES. Vacancies on the Board of Directors by
reason of death, resignation, removal, or otherwise, and newly created
directorships resulting from any increase in the number of directors may be
filled (other than directors elected by one or more series of Preferred Stock)
solely by a majority of the directors then in office (although less than a
quorum) or by a sole remaining director. Each director so chosen shall hold
office until such director's successor shall have been duly elected and
qualified or until such director's earlier death, resignation, disqualification
or removal. If, at the time of filling any vacancy or any newly created
directorship, the directors then in office shall constitute less than a majority
of the entire Board (as constituted immediately prior to any such increase), the
Court of Chancery may, upon application of any stockholder or stockholders
having the right to vote for such directors, summarily order an election to be
held to fill any such vacancies or newly created directorships, or to replace
the directors chosen by the directors then in office.

                  Section 3. REMOVAL. No director may be removed from office by
the stockholders except for cause with the affirmative vote of the holders of
two-thirds (66 2/3%) of all outstanding securities of the corporation then
entitled to vote generally in the election of directors, voting together as a
single class.

and do all such lawful acts and things as are not directed or required by
statute, by the Amended and Restated Certificate of Incorporation or by these
Bylaws to be exercised or done by the stockholders.

                  Section 5. PLACE OF DIRECTORS' MEETINGS. The directors may

Directors may be held without notice at such time and place as shall from time
to time be determined by the Board of Directors.

                  Section 7. SPECIAL MEETINGS. Special meetings of the Board of
Directors may be called by the Chairman of the Board or the President on
forty-eight hours' notice to each director, either personally or by mail,
telecopier, or other means of electronic transmission at the address of such
director on the books and records of the corporation; special meetings shall be
called by the President or the Secretary in like manner and on like notice on
the written request of two directors.

                  Section 8. QUORUM. At all meetings of the Board of Directors a
majority of the then authorized number of directors shall be necessary and
sufficient to constitute a quorum for the transaction of business, and the vote
of a majority of the directors present at any meeting at which there is a quorum
shall be the act of the Board of Directors, except as may be otherwise
specifically provided by statute, by the Amended and Restated Certificate of
Incorporation or by these Bylaws. If a quorum shall not be present at any
meeting of the Board of Directors, the directors present thereat may adjourn the
meeting from time to time, without notice other than announcement at the
meeting, until a quorum shall be present.

                  Section 9. ACTION WITHOUT MEETING. Unless otherwise restricted
by the Amended and Restated Certificate of Incorporation or these Bylaws, any
action required or permitted to be taken at 



                                       6
<PAGE>   10

any meeting of the Board of Directors or of any committee thereof may be taken
without a meeting, if all members of the Board of Directors or committee, as the
case may be, consent thereto in writing, and the writing or writings are filed
with the minutes of proceedings of the Board of Directors or committee.

                  Section 10. TELEPHONIC MEETINGS. Unless otherwise restricted
by the Amended and Restated Certificate of Incorporation or these Bylaws,
members of the Board of Directors, or any committee designated by the Board of
Directors, may participate in a meeting of the Board of Directors, or any
committee, by means of conference telephone or similar communications equipment
by means of which all persons participating in the meeting can hear each other,
and such participation in a meeting shall constitute presence in person at such
meeting.

                  Section 11. COMMITTEES OF DIRECTORS. The Board of Directors
may, by resolution passed by a majority of the entire Board of Directors,
designate one or more committees, each such committee to consist of one or more
of the directors of the corporation. The Board of Directors may designate one or
more directors as alternate members of any committee, who may replace any absent
or disqualified member at any meeting of the committee. In the absence or
disqualification of a member of a committee, the member or members thereof
present at any meeting and not disqualified from voting, whether or not he/she
or they constitute a quorum, may unanimously appoint another member of the Board
of Directors to act at the meeting in the place of any such absent or
disqualified member. Any such committee, to the extent provided in the
resolution of the Board of Directors, shall have and may exercise all the powers
and authority of the Board of Directors in the management of the business and
affairs of the corporation, and may authorize the seal of the corporation to be
affixed to all papers which may require it; but no such committee shall have the
power or authority in reference to amending the Amended and Restated Certificate
of Incorporation, adopting an agreement of merger or consolidation, recommending
to the stockholders the sale, lease or exchange of all or substantially all of
the corporation's property and assets, recommending to the stockholders a
dissolution of the corporation or a revocation of a dissolution, or amending the
Bylaws of the corporation; and, unless the resolution or the Amended and
Restated 


                                       7
<PAGE>   11

Certificate of Incorporation expressly so provide, no such committee shall have
the power or authority to declare a dividend or to authorize the issuance of
stock.

                  Section 12. MINUTES OF COMMITTEE MEETINGS. Each committee
shall keep regular minutes of its meetings and report the same to the Board of
Directors when required.

                  Section 13. COMPENSATION OF DIRECTORS. Unless otherwise
restricted by the Amended and Restated Certificate of Incorporation or these
Bylaws, the Board of Directors shall have the authority to fix the compensation
of directors. The directors may be paid their expenses, if any, of attendance at
each meeting of the Board of Directors and may be paid a fixed sum for
attendance at each meeting of the Board of Directors or a stated salary as
director. No such payment shall preclude any director from serving the
corporation in any other capacity and receiving compensation therefor. Members
of special or standing committees may be allowed like compensation for attending
committee meetings.

                                   ARTICLE IV

election of officers, the directors may by resolution determine the order of
their rank. Any number of offices may be held by the same person, unless the

                    INDEMNIFICATION OF DIRECTORS AND OFFICERS

                  (a) The corporation shall indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation) by
reason of the fact that he/she is or was a director, officer, employee or agent
of the corporation, or is or was serving at 



                                       11
<PAGE>   15

the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by him/her in connection with
such action or suit or proceeding if he/she acted in good faith and in a manner
he/she reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his/her conduct was unlawful. The termination of any
action, suit or proceeding by judgment, order, settlement, conviction, or upon a
plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which
he/she reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his/her conduct was unlawful.

                  (b) The corporation shall indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action or suit by or in the right of the corporation to procure a
judgment in its favor by reason of the fact that he/she is or was a director,
officer, employee or agent of the corporation, or is or was serving at the
request of the corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise against
expenses (including attorneys' fees) actually and reasonably incurred by him/her
in connection with the defense or settlement of such action or suit if he/she
acted in good faith and in a manner he/she reasonably believed in or not opposed
to the best interests of the corporation except that no such indemnification
shall be made in respect of any claim, issue or matter as to which such person
shall have been adjudged to be liable to the corporation unless and only to the
extent that the Court of Chancery of Delaware or the court in which such action
or suit was brought shall determine upon application that, despite the
adjudication of liability but in view of all the circumstances of the case, such
person is fairly and reasonably entitled to indemnity for such expenses which
such Court of Chancery or such other court shall deem proper.



                                       12
<PAGE>   16

                  (c) To the extent that a director, officer, employee or agent
of the corporation has been successful on the merits or otherwise in defense of
any action, suit or proceeding referred to in paragraphs (a) and (b), or in
defense of any claim, issue or matter therein, he/she shall be indemnified
against expenses (including attorneys' fees) actually and reasonably incurred by
him/her in connection therewith.

                  (d) Any indemnification under paragraphs (a) and (b) (unless
ordered by a court) shall made by the corporation only as authorized in the
specific case upon a determination that indemnification of the director,
officer, employee or agent is proper in the circumstances because he/she has met
the applicable standard of conduct set forth in paragraphs (a) and (b). Such
determination shall be made (1) by the Board of Directors by a majority vote of
a quorum consisting of directors who were not parties to such action, suit or
proceeding, or (2) if such a quorum is not obtainable, or, even if obtainable a
quorum of disinterested directors so directs, by independent legal counsel in a
written opinion, or (3) by the stockholders.

                  (e) Expenses incurred by an officer or director in defending
any civil or criminal, administrative or investigative action, suit or
proceeding shall be paid by the corporation in advance of the final disposition
of such action, suit or proceeding upon receipt of an undertaking by or on
behalf of such director or officer to repay such amount if it shall ultimately
be determined that he/she is not entitled to be indemnified by the corporation
as authorized in this Article V. Such expenses incurred by other employees and
agents may be so paid upon such terms and conditions, if any, as the Board of
Directors deems appropriate.

                  (f) The indemnification and advancement of expenses provided
by, or granted pursuant to, the other paragraphs of this Article V shall not be
deemed exclusive of any other rights to which those seeking indemnification or
advancement of expenses may be entitled under any bylaw, agreement, vote of
stockholders or disinterested directors or otherwise, both as to action in
his/her official capacity and as to action in another capacity while holding
such office.

<PAGE>   17

                  (g) The Board of Directors may authorize, by a vote of a
majority of a quorum of the Board of Directors, the corporation to purchase and
maintain insurance on behalf of any person who is or was a director, officer,
employee or agent of the corporation, or is or was serving at the request of the
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise against any liability
asserted against him/her and incurred by him/her in any such capacity, or
arising out of his/her status as such, whether or not the corporation would have
the power to indemnify him/her against such liability under the provisions of
this Article V.

                  (h) For the purposes of this Article V, references to "the
corporation" shall include, in addition to the resulting corporation, any
constituent corporation (including any constituent of a constituent) absorbed in
a consolidation or merger which, if its separate existence had continued would
have had power and authority to indemnify its directors, officers and employees
or agents, so that any person who is or was a director, officer, employee or
agent of such constituent corporation, or is or was serving at the request of
such constituent corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
shall stand in the same position under the provisions of this Article V with
respect to the resulting or surviving corporation as he/she would have with
respect to such constituent corporation if its separate existence had continued.

                  (i) For purposes of this section, references to "other
enterprises" shall include employee benefit plans; references to "fines" shall
include any excise taxes assessed on a person with respect to an employee
benefit plan; references to serving at the request of the "corporation" shall
include service as a director, officer, employee or agent of the corporation
which imposes duties on, or involves services by, such director, officer,
employee or agent with respect to an employee benefit plan, its participants or
beneficiaries; and a person who acted in good faith and in a manner he/she
reasonably believed to be in the best interest of the participants and
beneficiaries of an employee benefit plan shall be deemed to have acted in a
manner not opposed to the best interests of the "corporation" as referred to in
this section.

<PAGE>   18

                  (j) The indemnification and advancement of expenses provided
by, or granted pursuant to, this Article V shall, unless otherwise provided when
authorized or ratified, continue as to a person who has ceased to be a director,
officer, employee or agent and shall inure to the benefit of the heirs,
executors and administrators of such a person.

                                   ARTICLE VI

                     INDEMNIFICATION OF EMPLOYEES AND AGENTS

                  The corporation may, at its option, indemnify every person who
was or is a party or is or was threatened to be made a party to any action,
suit, or proceeding, whether civil, criminal, administrative or investigative,
by reason of the fact that he/she is or was an employee or agent of the
corporation or, while an employee or agent of the corporation, is or was serving
at the request of the corporation as an employee or agent or trustee of another
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise, against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by him/her in
connection with such action, suit or proceeding, to the extent permitted by
applicable law.

                                   ARTICLE VII

or registrar before such certificate is issued, it may be issued by the
corporation with the same effect as if he/she were such officer, transfer agent,
or registrar at the date of issue.

                  Section 3. STATEMENT OF STOCK RIGHTS, PREFERENCES, PRIVILEGES.
If the corporation shall be authorized to issue more than one class of stock or

certificate or certificates, or his/her legal representative, to advertise the

expressly provided by the laws of the State of Delaware.

               1.4 "Person" means any natural person, partnership, corporation,
limited liability company, trust, association, or other legal entity.

               1.5 "Qualified Initial Public Offering" means the Company's (or a
successor's to the Company's business) first underwritten initial public
offering of common equity interests under the Securities Act of 1933, as amended
(the "Securities Act") after the date hereof, that results in such common equity
interests being listed for trading on a national securities exchange or being
authorized for trading on the Nasdaq National Market System at such time.

               1.6 "Qualified Transfer" means (i) any transfer of shares of
Common Stock by will or pursuant to the laws of descent and distribution to any
member or members of a Stockholder's Family, (ii) any transfer of shares of
Common Stock by a Stockholder to a domestic trust created for the sole benefit
of one or more of the Stockholder or any member or members of the Stockholder's
Family, (iii) any transfer of shares of Common Stock from a trust described in
clause (ii) above to the Stockholder (or former Stockholder) who transferred
shares of Common Stock to such trust, and (iv) any transfer to a domestic
limited partnership or a domestic limited liability company if there are no
partners or members of such limited partnership or limited liability company
other than the Stockholder and members of the Stockholder's Family; (v) any
transfer of Common Stock from a limited partnership or limited liability company
described in clause (iv) above to the Stockholder (or former Stockholder) who
transferred Common Stock to such limited partnership or limited liability
company; and (vii) any transfer of 



                                       2
<PAGE>   3

shares of Common Stock from one Stockholder to another Stockholder; provided
that none of the above transfers shall constitute a "Qualified Transfer" unless
(a) the transferee agrees in writing to be bound by the terms and provisions of
this Agreement as a Stockholder, and specifically, without limiting the
generality of the foregoing, agrees that (i) the repurchase option provision of
Section 4.4 hereof (and if and to the extent such provision is modified by an
employment agreement, then as so modified) shall continue to apply to such
Common Stock as if they had not been transferred, (ii) to the extent the Common
Stock was Founders' Interests in the hands of the transferor, the restrictions
contained in Section 4.5 hereof shall continue to apply to such as Common Stock
as if they had not been transferred, (iii) to the extent that such Common Stock
was received by the transferor pursuant to the Company's 1998 Equity
Participation Plan, all provisions of the Company's 1998 Equity Participation
Plan, the Equity Participation Agreement by which such Common Stock was awarded,
the transferor's employment agreement with the Company or a subsidiary, if any,
and all relevant provisions of this Agreement shall continue to apply to such
shares of Common Stock as if they had not been transferred, and (iv) to the
extent the ownership of any shares of Common Stock which are held in an escrow
are so transferred, such shares of Common Stock shall remain subject to the
provisions of such escrow agreement as if they had not been transferred, and (b)
the Company receives an opinion of counsel reasonably acceptable to the Company
that such transfer does not violate federal or state securities laws (if the
Stockholder represents to the Company in writing that the transfer was made as a
bona fide gift without payment of consideration, no securities law opinion is
required), and further provided that if the transfer is to a limited
partnership, limited liability company, or trust of which the Stockholder (or
former Stockholder) is not the trustee, then such transfer will not constitute a
"Qualified Transfer" unless the limited partnership, limited liability company,
or trustee, as the case may be, gives a proxy to vote such shares of Common
Stock to a person acceptable to the Company. Any Stockholder or any person or
entity designated as a "Shareholder Representative" pursuant to the Exchange
Agreement or an escrow agreement to which the Company or Nextera is a party
shall be deemed acceptable to the Company. Any such proxy shall be deemed to be
terminated upon a Qualified Initial Public Offering. Qualified Transfer shall
also mean (i) any transfer or sale of shares of Common Stock between a
Stockholder and the Company or Nextera to satisfy an indemnification claim and
(ii) any pledge of shares of Common Stock pursuant to an escrow agreement to
which the Company or Nextera is a party.

          2. Representations and Warranties of each Stockholder. Each
Stockholder hereby, severally and not jointly, represents and warrants to
Nextera as of the date hereof in respect of himself or itself that such
Stockholder has all requisite power and authority to enter into this Agreement
and to consummate the transactions contemplated hereby. This Agreement has been
duly authorized, executed and delivered by the Stockholder and constitutes a
valid and binding obligation of the Stockholder enforceable against the
Stockholder in accordance with its terms (assuming the due authorization,
execution and delivery by the other parties hereto), subject to the effect of
any applicable bankruptcy, reorganization, insolvency, moratorium or similar
laws affecting creditors' rights generally and subject to the effect of general
principles of equity, including, without limitation, the possible unavailability
of specific performance or injunctive relief, regardless of whether considered
in a proceeding in equity or at law.



                                       3

          3. Representations and Warranties of Nextera and the Company. Nextera
hereby represents and warrants to each Stockholder that Nextera has all
requisite limited liability company power and authority, and that the Company
hereby represents and warrants that it has all requisite corporate power and
authority, to enter into this Agreement and to consummate the transactions
contemplated hereby. This Agreement has been duly authorized, executed and
delivered by Nextera and the Company, and constitutes a valid and binding
obligation of Nextera and the Company, enforceable against Nextera and the
Company in accordance with its terms (assuming the due authorization, execution
and delivery by the other parties hereto), subject to the effect of any
applicable bankruptcy, reorganization, insolvency, moratorium or similar laws
affecting creditors' rights generally and subject to the effect of general
principles of equity, including, without limitation, the possible unavailability
of specific performance or injunctive relief, regardless of whether considered
in a proceeding in equity or at law.

          4. Transfers of Interests.

               4.1 General. Except as otherwise provided in Sections 4.2 and
4.4, a Stockholder may not sell, assign, pledge, hypothecate, transfer, exchange
or otherwise dispose of (collectively "Assign") or offer to Assign, in whole or
in part, his or its Common Stock unless Stockholders holding a majority of the
Common Stock subject to the Agreement approve of such Assignment; provided,
however, that, Sections 4.1, 4.2, 4.3 and 4.4 hereof shall no longer apply if a
Stockholder desires to Assign his or its Common Stock following a Qualified
Initial Public Offering.

               4.2 Qualified Transfer. A Stockholder may, without consent,
transfer some or all of his or its shares of Common Stock pursuant to a
Qualified Transfer.

               4.3 Transferee Not A Stockholder. If a Stockholder attempts to
Assign, in whole or in part, his or its Common Stock in violation of Section
4.1, such assignment shall be void ab initio and of no effect and the purported
transferee shall not be recognized as a Stockholder and shall have no right to
participate in the business and affairs of the Company.

               4.4 Repurchase Option. Prior to a Qualified Initial Public
Offering, the Company shall have the right, but not an obligation, to repurchase
the shares of Common Stock of any Stockholder who is employed by or similarly
associated with the Company or any other entity controlled by or affiliated with
the Company at such time as such Stockholder is no longer employed by or so
associated with the Company or such other entity for any reason. For a six month
period (the "Repurchase Option Period") following such termination, the Company
shall have an option (the "Repurchase Option") to repurchase all or any portion
of the shares of Common Stock held by such Stockholder. If the Company so elects
to exercise the Repurchase Option in whole or in part, it shall give written
notice of such (the "Repurchase Notice") to such Stockholder (or his estate or
legal representative, as the case may be) during the Repurchase Option Period.
The fair market value of such Stockholder's shares of Common Stock being
repurchased shall be determined by the Board of Directors of the Company (the
"Board") and the Board shall give notice (the "Valuation Notice") of such
determination to such Stockholder (or his estate or legal representative, as the
case may be) within thirty (30) days of the Repurchase 



                                       4
<PAGE>   5

Notice. If such Stockholder (or his estate or legal representative, as the case
may be) does not dispute the fair market value of the shares of Common Stock
being repurchased within the time period specified below for giving the
Appraisal Notice, then the Company shall pay to such Stockholder (or his estate
or legal representative, as the case may be), in cash and within thirty days of
the date of the Valuation Notice, the fair market value of the shares of Common
Stock being repurchased. If such Stockholder (or his estate or legal
representative, as the case may be) disputes the fair market value of the shares
of Common Stock being repurchased as set forth in the Valuation Notice, then
such Stockholder (or his estate or legal representative, as the case may be)
shall so notify the Board in writing (the "Appraisal Notice") within five (5)
business days of receipt of the Valuation Notice. Within fifteen (15) business
days of the receipt of the Appraisal Notice, the Board and such Stockholder (or
his estate or legal representative, as the case may be) shall each appoint a
professional appraiser to determine the fair market value of the shares of
Common Stock being repurchased. Each appraiser shall have at least five (5)
years experience in appraising companies similar to the Company. The two
appraisers shall within the succeeding twenty (20) day period after their
selection, attempt to reach agreement on the fair market value. If the
appraisers reach such agreement, their agreement shall be final and binding on
the Company and such Stockholder (or his estate or legal representative, as the
case may be). If the appraisers fail to agree, they shall within ten (10) days
thereafter select a third appraiser with the same qualification requirements,
and the three (3) appraisers shall establish the fair market value by majority
vote within the succeeding twenty (20) day period and such determination of the
fair market value shall be final and binding on the Company and such Stockholder
(or his estate or legal representative, as the case may be). In all events, the
appraisers selected shall be unaffiliated with and otherwise independent of the
Company, the Board, such Stockholder and their affiliates. If the fair market
value of the shares of Common Stock being repurchased, as determined by the
appraisers, is less than or no more than five percent (5%) greater than the
value as determined by the Board, then such Stockholder (or his estate or legal
representative, as the case may be) shall pay all costs associated with the
appraisers, and such costs shall be deducted from the amount owed by the
Company. If the fair market value as determined by the appraisers is more than
five percent (5%) greater than the value as determined by the Board, then the
Company shall pay for all costs associated with the appraisers. Notwithstanding
the provisions of this Section 4.4, if such a Stockholder has an employment
contract with the Company or an entity controlled by or affiliated with the
Company and such employment contract provides for the repurchase of shares of
Common Stock being repurchased upon such Stockholder's termination of
employment, then to the extent there is any conflict between the terms of this
Section 4.4 and the terms of the employment contract, the terms of the
employment contract shall govern.

               4.5 Restrictions on Sale or Transfer After a Qualified Initial
Public Offering. If there is a Qualified Initial Public Offering of the Company
or a successor to the Company's business, then, subject to all applicable market
and legal restrictions, each Stockholder that holds Founders' Interests hereby
agrees and covenants that such Stockholder will not Assign any of such
Stockholder's Founders' Interests for a six month period following the Qualified
Initial Public Offering, and that subsequent to such six month period, such
Stockholder: (A) will not Assign more than one-third of such Founders' Interests
in the twelve calendar month period following such six month period; and (B)
will not Assign more than a total of two-thirds of such Founders' Interests in
the twenty-four calendar month period following such six month period.



                                       5
<PAGE>   6

               4.6 Compliance with Securities Laws. Each Stockholder agrees and
covenants that such Stockholder will not Assign any of his or its Common Stock
except in compliance with all applicable securities laws.

          5. Registration Rights. The Stockholders shall have registration
rights as specified in this Section 5.

               5.1 Piggyback Registration Rights.

                    5.1.1 Right to Piggyback. Whenever the Company proposes to
          register any Common Stock (or securities convertible into or
          exchangeable for, or options to purchase, Common Stock) with the
          Securities and Exchange Commission (the "Commission") under the
          Securities Act of 1933, as amended (the "Securities Act") and the
          registration form to be used may be used for the registration of the
          "Registrable Securities," as defined in Section 5.9 hereof (a
          "Piggyback Registration"), the Company (i) will give written notice to
          all Stockholders who hold Registrable Securities (collectively,
          "Holders") and each holder of an option to purchase Registrable
          Securities, no later than the later of (a) 45 days prior to the
          anticipated filing date or (b) promptly following its decision to
          file, of its intention to effect such a registration, which notice
          will specify the proposed offering price (or reasonable range
          thereof), the kind and number of securities proposed to be registered,
          the distribution arrangements and such other information that at the
          time would be appropriate to include in such notice, and (ii) will,
          subject to Section 5.1.2 below, include in such Piggyback Registration
          all Registrable Securities with respect to which the Company has
          received written requests for inclusion therein within 20 days after
          the date of the Company's notice. Notwithstanding the foregoing, the
          rights provided in this Section 5.1 shall not apply to the Qualified
          Initial Public Offering as long as no Stockholder is allowed to sell
          any Common Stock in such Qualified Initial Public Offering. The
          Company shall reasonably cooperate with the holders of options to
          purchase Registrable Securities in connection with such holders'
          desire, if any, to exercise such options contemporaneously with the
          sale of the underlying Registrable Securities.

                    5.1.2 Priority on Piggyback Registrations. If the managing
          underwriter or underwriters, if any, advise the selling Holders in
          writing that in its or their reasonable opinion or, in the case of a
          Piggyback Registration not being underwritten, the Company shall
          reasonably determine (and notify the selling Holders of such
          determination), based upon the written advice of an independent
          investment banker of nationally recognized standing, a copy of which
          advice shall also be delivered to the selling Holders, that the number
          or kind of securities proposed to be sold in such registration
          (including Registrable Securities to be included pursuant to Section
          5.1.1 above) is inconsistent with that which can be sold in such
          registration without having a material adverse effect on the success
          of the offering (including, without limitation, an impact on the
          selling price or the number of securities that any participant may
          sell), the Company will include in such registration the number of
          securities, if any, which, in the opinion of such underwriter or
          underwriters, or the Company, based upon the advice of an independent
          investment banker of nationally recognized standing, as the case may
          be, can be sold as follows: (i) first, the Common



                                       6
<PAGE>   7

          Stock the Company proposes to sell and (ii) second, the Registrable
          Securities requested to be included in such registration by the
          Holders. To the extent that the privilege of including Registrable
          Securities in any Piggyback Registration must be allocated among the
          selling Holders pursuant to clause (ii) above, the allocation shall be
          made pro rata based on the number of Registrable Securities that each
          such Holder shall have requested to include therein.

                    5.1.3 Selection of Underwriters. If any Piggyback
          Registration is an underwritten offering, the Company will (i) select
          a managing underwriter or underwriters to administer the offering,
          which managing underwriter or underwriters will be of nationally
          recognized standing and (ii) determine the terms under which such
          underwriting shall take place.

                    5.1.4 Withdrawal. A request for Piggyback Registration may
          be withdrawn by any Holder making such a request provided that such
          Holder reimburses the Company for all expenses reasonably incurred by
          the Company in connection with the request.

               5.2 Demand Registration Rights.

                    5.2.1 Right to Demand. After 180 days after a Qualified
          Initial Public Offering, Knowledge Enterprises, Inc. or an affiliate
          thereof that then owns an equity interest in the Company may make a
          one time written request of the Company for registration with the
          Commission, under and in accordance with the provisions of the
          Securities Act, of all or part of its Registrable Securities (a
          "Demand Registration"); provided, however, that (x) the Company need
          not effect a Demand Registration unless such Demand Registration shall
          include at least 10% of the issued and outstanding Common Stock of the
          Company and (y) the Company may, if the Board determines in the
          exercise of its reasonable judgment that effecting such Demand
          Registration at such time would have a material adverse effect on the
          Company, defer such Demand Registration for a single period not to
          exceed 180 days. Within 10 days after receipt of the request for a
          Demand Registration, the Company will send written notice (the
          "Notice") of such registration request and its intention to comply
          therewith to each of the other Holders and each holder of an option to
          purchase Registrable Securities and, subject to Section 5.2.3 below,
          the Company will include in such registration all Registrable
          Securities of the Holders with respect to which the Company has
          received written requests for inclusion therein within 20 business
          days after the effectiveness of the Notice. All requests made pursuant
          to this Section 5.2.1 will specify the aggregate number of Registrable
          Securities requested to be registered and will also specify the
          intended methods of disposition thereof. The Company shall reasonably
          cooperate with the holders of options to purchase Registrable
          Securities in connection with such holders' desire, if any, to
          exercise such options contemporaneously with the sale of the
          underlying Registrable Securities.



                                       7
<PAGE>   8

                    After 180 days after a Qualified Initial Public Offering,
          Holders who together hold at least 10% of the issued and outstanding
          Common Stock of the Company may make a one time written request of the
          Company for a Demand Registration on the terms set forth above.

                    5.2.2 Expenses; Number of Demand Registrations; Withdrawal.
          The expenses of each Demand Registration (including the fees and
          expenses of a total of one counsel for the selling Holders in
          accordance with Section 5.5.2 below) shall be borne by the Company. A
          Demand Registration shall not be counted as a Demand Registration
          hereunder until such Demand Registration has been declared effective
          by the Commission and maintained continuously effective for a period
          of at least six months or such shorter period when all Registrable
          Securities included therein have been sold in accordance with such
          Demand Registration. A Demand Registration may be withdrawn by the
          Holders making the demand without the demand counting as a Demand
          Registration hereunder provided that the Holders making the demand
          reimburse the Company for all reasonable expenses incurred by the
          Company in connection with the demand.

                    If the Company elects to issue and sell any equity
          securities pursuant to any Registration Statement filed in connection
          with a Demand Registration, then such Registration shall be deemed not
          to be a Demand Registration solely for purposes of determining the
          number of Demand Registrations granted by this Section 5.2.2.

                    5.2.3 Priority on Demand Registrations. If in any Demand
          Registration the managing underwriter or underwriters thereof advise
          the Company in writing that in its or their reasonable opinion (or in
          the case of a Demand Registration not being underwritten, the Company
          shall reasonably determine (and notify the selling Holders of such
          determination)), based upon the written advice of an independent
          investment banker of nationally recognized standing, a copy of which
          advice shall also be delivered to the selling Holders, that the number
          of securities proposed to be sold in such Demand Registration is
          inconsistent with that which can be sold in such offering without
          having a material adverse effect on the success of the offering
          (including, without limitation, an impact on the selling price or the
          number of Registrable Securities that any participating Holder may
          sell), the Company will include in such registration only the number
          of securities that, in the reasonable opinion of such underwriter or
          underwriters (or the Company, based upon the advice of an independent
          investment banker of nationally recognized standing, as the case may
          be) can be sold without having a material adverse effect on the
          success of the offering as follows: (i) first, the Registrable
          Securities requested to be included in such Demand Registration by
          Holders pro rata on the basis of the number of Registrable Securities
          requested to be included and (ii) second, any securities held by
          persons other than the Holders and requested to be included in such
          Demand Registration.

                    5.2.4 Selection of Underwriters. The Company shall have the
          right to determine whether any Demand Registration shall be
          underwritten or not underwritten. If any Demand Registration is an
          underwritten offering, the Company will (i) select a managing
          underwriter or underwriters to administer the offering, which managing


                                       8
<PAGE>   9
          underwriter or underwriters shall be of nationally recognized standing
          and (ii) determine the terms under which such underwriting shall take
          place.

               5.3 Registration Procedures. With respect to any Piggyback
          Registration or Demand Registration (generically, a "Registration"),
          the Company will, subject to Sections 5.1.2 and 5.2.3, as
          expeditiously as practicable:

                    5.3.1 Prepare and file with the Commission, within 90 days
          after mailing the applicable Notice, a registration statement or
          registration statements (the "Registration Statement") relating to the
          applicable Registration on any appropriate form under the Securities
          Act, which form shall be available for the sale of the Registrable
          Securities in accordance with the intended method or methods of
          distribution thereof; provided, however, that the Company will include
          in any Registration Statement on a form other than Form S-1 all
          information that the selling Holders shall reasonably request and
          shall include all financial statements required by the Commission to
          be filed therewith, cooperate and assist in any filings required to be
          made with the National Association of Securities Dealers, Inc.
          ("NASD") and use its best efforts to cause such Registration Statement
          to become effective; provided further, that before filing a
          Registration Statement or prospectus related thereto (a "Prospectus")
          or any amendments or supplements thereto, the Company will furnish to
          the Holders covered by such Registration Statement and the
          underwriters, if any, copies of all such documents proposed to be
          filed, which documents will be subject to the reasonable review of
          such Holders and underwriters and their respective counsel, and the
          Company will not file any Registration Statement or amendment thereto
          or any Prospectus or any supplement thereto to which the holders of a
          majority of the Registrable Securities covered by such Registration
          Statement or the underwriters, if any, shall reasonably object;

                    5.3.2 Prepare and file with the Commission such amendments
          and post-effective amendments to the Registration Statement as may be
          necessary to keep each Registration Statement effective for the
          applicable period, or such shorter period which will terminate when
          all Registrable Securities covered by such Registration Statement have
          been sold; cause each Prospectus to be supplemented by any required
          Prospectus supplement, and as so supplemented to be filed pursuant to
          Rule 424 under the Securities Act; and comply with the provisions of
          the Securities Act with respect to the disposition of all securities
          covered by such Registration Statement during the applicable period in
          accordance with the intended method or methods of distribution by the
          sellers thereof set forth in such Registration Statement or supplement
          to the Prospectus. The Company shall not be deemed to have used its
          best efforts to keep a Registration Statement effective during the
          applicable period if it voluntarily takes any action that would result
          in selling Holders covered thereby not being able to sell such
          Registrable Securities during that period unless such action is
          required under applicable law, provided that the foregoing shall not
          apply to actions taken by the Company in good faith and for valid
          business reasons, including, without limitation, the acquisition or
          divestiture of assets, so long as the Company promptly thereafter
          complies with the requirements of Section 5.3.11 below, if applicable;

          underwriters, if any, promptly, and (if requested by any such person
          or entity) confirm such advice in writing, (A) when the Prospectus or
          any Prospectus supplement or post-effective amendment has been filed,
          and, with respect to the Registration Statement or any post-effective
          amendment, when the same has become effective, (B) of any request by
          the Commission for amendments or supplements to the Registration
          Statement or the Prospectus or for additional information, (C) of the
          issuance by the Commission of any stop order suspending the
          effectiveness of the Registration Statement or the initiation of any
          proceedings for that purpose, (D) if at any time the representations
          and warranties of the Company contemplated by Section 5.3.14 below
          cease to be true and correct, (E) of the receipt by the Company of any
          notification with respect to the suspension of the qualification of
          the Registrable Securities for sale in any jurisdiction or the
          initiation or threatening of any proceeding for such purpose and (F)
          of the happening of any event which makes any statement made in the
          Registration Statement, the Prospectus or any document incorporated
          therein by reference untrue or which requires the making of any
          changes in the Registration Statement, the Prospectus or any document
          incorporated therein by reference in order to make the statements
          therein not misleading;

                    5.3.4 Make every reasonable effort to obtain the withdrawal
          of any order suspending the effectiveness of the Registration
          Statement at the earliest possible moment;

                    5.3.5 If requested by the managing underwriter or
          underwriters or a holder of Registrable Securities being sold in
          connection with an underwritten offering, promptly incorporate in a
          Prospectus supplement or post-effective amendment such information as
          the managing underwriters and the holders of a majority of the
          Registrable Securities being sold agree should be included therein
          relating to the plan of distribution with respect to such Registrable
          Securities, including, without limitation, information with respect to
          the number of Registrable Securities being sold to such underwriters,
          the purchase price being paid therefor by such underwriters and with
          respect to any other terms of the underwritten offering of the
          Registrable Securities to be sold in such offering; and make all
          required filings of such Prospectus supplement or post-effective
          amendment as soon as notified of the matters to be incorporated in
          such Prospectus supplement or post-effective amendment;

                    5.3.6 Furnish to each managing underwriter and, if requested
          by the holders of a majority of the Registrable Securities being sold,
          to each selling Holder, without charge, at least one signed copy of
          the Registration Statement and any amendment thereto, including

          if any, without charge, as many copies of the Prospectus (including
          each preliminary prospectus) and any amendment or supplement thereto
          as such Holder and underwriters may reasonably request. The Company
          consents to the use of each Prospectus or any amendment or supplement
          thereto by each of the selling Holders and the underwriters, if any,
          in

          jurisdictions as any seller or underwriter reasonably requests in
          writing, considering the amount of Registrable Securities proposed to
          be sold in each such jurisdiction, and do any and all other acts or
          things necessary or advisable to enable the disposition in such
          jurisdictions of the Registrable Securities covered by the
          Registration Statement; provided, however, that the Company will not
          be required to qualify generally to do business in any jurisdiction
          where it is not then so qualified or to take any action that would
          subject it to general service of process in any such jurisdiction
          where it is not then so subject;

                    5.3.9 Cooperate with the selling Holders and the managing
          underwriters, if any, to facilitate the timely preparation and

          amendment to the Registration Statement or the related Prospectus or
          any document incorporated therein by reference or file any other
          required document so that, as thereafter delivered to the purchasers
          of the Registrable Securities, the Prospectus will not contain an
          untrue statement of a material fact or omit to state any material fact
          necessary to make the statements therein not misleading;

                    5.3.12 Cause all Registrable Securities covered by any

          to be incorporated by reference into any Registration Statement or
          Prospectus (after initial filing of the Registration Statement),
          provide copies of such document to counsel to the selling Holders and
          to the managing underwriters, if any, make the Company's
          representatives available for discussion of such document and make
          such changes in such document prior to the filing thereof as counsel
          for such selling Holders or underwriters may reasonably request; and

                    5.3.18 Keep each seller of Registrable Securities advised in
          writing as to the initiation and progress of any Registration
          hereunder.

               The Company may require each seller of Registrable Securities as
to which any Registration is being effected to furnish to the Company such
information regarding the proposed distribution of such securities as the
Company may from time to time reasonably request in writing.

               Each Holder of Registrable Securities agrees by acquisition of
such Registrable Securities that, upon receipt of any notice from the Company of
the happening of any event of the kind described in Section 5.3.3(F), such
Holder will forthwith discontinue disposition of Registrable Securities pursuant
to the Registration Statement until such Holder (i) has received copies of the
supplemented or amended Prospectus as contemplated by Section 5.3.11 above or
until such Holder is advised in writing (the "Advice") by the Company that the
use of the Prospectus may be resumed and (ii) has received copies of any
additional or supplemental filings that are incorporated by reference in the
Prospectus, and, if so directed by the Company, such Holder will deliver to the
Company (at the Company's expense) all copies, other than permanent file copies
then in such Holder's possession, of the Prospectus covering such Registrable
Securities. In the event the Company shall give any such notice, the six-month
time period referred to in Section 5.2.2 shall be extended by the number of days
during the period from and including the date of the giving of such notice to
and including the date when each seller of Registrable Securities covered by
such Registration Statement shall have received the copies of the supplemented
or amended prospectus contemplated by Section 5.3.3(F) or the Advice.

               5.4 Restrictions on Public Sale.

                    5.4.1 Public Sale by Holders. To the extent not inconsistent
          with applicable law, each Holder (i) agrees not to effect any public
          sale or distribution of Common Stock, including a sale pursuant to

          Act, during the 180-day period (or such shorter period as may be
          agreed to by the managing underwriter or underwriters) following a
          Qualified Initial Public Offering and (ii) whose Registrable
          Securities are included in a Registration Statement hereunder, if

          Registrable Securities, including a sale pursuant to Rule 144 (or any
          similar provision then in force) under the Securities Act, during the

          shorter period as may be agreed to by such underwriter or
          underwriters) beginning on, the



                                       13

          Registration or Demand Registration (except as part of such Piggyback
          or Demand Registration).

                    5.4.2 Public Sale by the Company. If requested by the
          managing underwriter or underwriters for any underwritten Registration
          or by the holders of a majority of the Registrable Securities being
          registered in a Demand Registration that is not being underwritten,
          (i) the Company will not effect any public sale or distribution of
          Common Stock (or securities convertible into or exchangeable or
          exercisable for Common Stock) for its own account during the 15
          business days prior to, and during the 90-day period beginning on, the
          effective date of such Registration and (ii) the Company will use its
          best efforts to cause each other holder of Common Stock (or securities
          convertible into or exchangeable for, or options to purchase, Common
          Stock) purchased from the Company at any time after the date hereof
          (other than in a registered public offering) to agree not to effect
          any public sale or distribution of any such securities during the
          period described in (i) above (except as part of such Registration, if
          otherwise permitted).

                    5.4.3 Other Registrations. If the Company has previously
          filed a Registration Statement with respect to Registrable Securities,
          and if such previous Registration has not been withdrawn or abandoned,
          the Company will not file or cause to be effected any other
          registration of any of its Common Stock (or securities convertible
          into or exchangeable for, or options to purchase, Common Stock) under
          the Securities Act (except on Form S-4 or S-8 or any similar successor
          forms), whether on its own behalf or at the request of any holder or
          holders of Common Stock (or securities convertible into or
          exchangeable or exercisable for Common Stock), until a period of at
          least six months has elapsed from the effective date of such previous
          Registration; provided, however, that if the holders of 50% or more of
          the aggregate number of Registrable Securities included in such
          previous Registration shall agree in writing, such period may be
          shortened by the Company but not to a period shorter than three
          months.

               5.5 Registration Expenses.

                    5.5.1 All expenses incident to the Company's performance of

          Market System and all other costs and expenses incurred by the Company
          in connection with any Registration hereunder; provided, however,
          that, except as otherwise provided in Section 5.5.2 below, the Company
          shall not bear the costs and expenses of any selling Holder for
          underwriters' commissions, brokerage fees or transfer taxes, or the
          fees and expenses of any counsel, accountants or other representative
          retained by any selling Holder.

                    5.5.2 Notwithstanding the foregoing, in connection with each
          Demand Registration hereunder, the Company will reimburse the selling
          Holders for the reasonable fees and disbursements of not more than one
          counsel (up to a maximum of $25,000). Such counsel shall be chosen by
          the holders of a majority of the Registrable Securities covered by the
          Registration, subject to the approval of the Company (which approval
          shall not unreasonably be withheld).

               5.6 Indemnification.

                    5.6.1 Indemnification by the Company. The Company agrees to
          indemnify, to the full extent permitted by law, each Holder, its
          officers, directors and agents and each person who controls such
          Holder within the meaning of the Securities Act and the Securities
          Exchange Act of 1934, as amended (the "Exchange Act") (each, an
          "Indemnified Holder"), against all losses, claims, damages,
          liabilities and expenses caused by any untrue or alleged untrue
          statement of a material fact contained in any Registration Statement,
          Prospectus or preliminary Prospectus or any omission or alleged
          omission to state therein a material fact necessary to make the
          statements therein (in the case of a Prospectus or any preliminary
          Prospectus, in light of the circumstances under which they were made)
          not misleading, except to the extent that such untrue statement or
          omission is caused by any information with respect to such Indemnified
          Holder furnished in writing to the Company by such Indemnified Holder
          or its representative expressly for use therein. The Company will also
          indemnify underwriters, selling brokers, dealer managers and similar
          securities industry professionals participating in the distribution,
          their officers and directors and each person who controls such persons
          (within the meaning of the Securities Act) to the same extent as
          provided above with respect to Indemnified Holders; provided, however,
          that if pursuant to an underwritten public offering of Registrable
          Securities, the Company and any underwriters enter into an
          underwriting or purchase agreement relating to such offering that
          contains provisions relating to indemnification and contribution
          between the Company and such underwriters, such provisions shall be
          deemed to govern indemnification and contribution as between the
          Company and such underwriters.

                    5.6.2 Indemnification by Holders of Registrable Securities.
          In connection with any Registration, each Holder participating therein
          will furnish to the Company in writing such information with respect
          to the Holder as the Company reasonably requests for use in connection
          with any Registration Statement, Prospectus or preliminary Prospectus
          and agrees to indemnify, to the full extent permitted by law, the
          Company, the directors and officers of the Company signing the
          Registration Statement and each person who controls the Company
          (within the meaning of the Securities Act and the Exchange Act)
          against any losses, claims, damages, liabilities and expenses
          resulting from any untrue 



                                       15

          statement of a material fact or any omission to state a material fact
          required to be stated therein or necessary to make the statements in
          the Registration Statement, Prospectus or preliminary Prospectus (in
          the case of the Prospectus or any preliminary Prospectus, in light of
          the circumstances under which they were made) not misleading, to the
          extent, and only to the extent, that such untrue statement or omission
          is caused by any information with respect to the Holder so furnished
          in writing by the Holder or its representative specifically for
          inclusion therein. In no event shall the liability of any selling
          Holder hereunder be greater in amount than the dollar amount of the
          proceeds received by such Holder upon the sale of the Registrable
          Securities giving rise to such indemnification obligation. The Company
          shall be entitled to receive indemnities from underwriters, selling
          brokers, dealer managers and similar securities industry professionals
          participating in the distribution, to the same extent as provided
          above with respect to information with respect to such persons or
          entities so furnished in writing by such persons or entities or their
          representatives specifically for inclusion in any Registration
          Statement, Prospectus or preliminary Prospectus.

                    5.6.3 Conduct of Indemnification Proceedings. Any person or
          entity entitled to indemnification hereunder will (i) give prompt
          written notice to the indemnifying party after the receipt by the
          indemnified party of a written notice of the commencement of any
          action, suit, proceeding or investigation or threat thereof made in
          writing for which such indemnified party will claim indemnification or
          contribution pursuant to this Agreement; provided, however, that the
          failure of any indemnified party to give notice as provided herein
          shall not relieve the indemnifying party of its obligations under the
          preceding Section 5.6.1 or 5.6.2, as applicable, except to the extent
          that the indemnifying party is actually prejudiced by such failure to
          give notice and (ii) unless in such indemnified party's reasonable
          judgment a conflict of interest may exist between such indemnified and
          indemnifying parties with respect to such claim, permit such
          indemnifying party to assume the defense of such claim with counsel
          reasonably satisfactory to the indemnified party. Whether or not such
          defense is assumed by the indemnifying party, the indemnifying party
          will not be subject to any liability for any settlement made without
          its consent (but such consent will not be unreasonably withheld). No
          indemnifying party will be required to consent to the entry of any
          judgment or to enter into any settlement that does not include as an
          unconditional term thereof the giving by the claimant or plaintiff of
          a release from all liability in respect of such claim or litigation.
          An indemnifying party who is not entitled to, or elects not to, assume
          the defense of a claim will not be obligated to pay the fees and
          expenses of more than one counsel in any one jurisdiction for all
          parties indemnified by such indemnifying party with respect to such
          claim, unless in the reasonable judgment of any indemnified party a
          conflict of interest may exist between such indemnified party and any
          other of such indemnified parties with respect to such claim, in which
          event the indemnifying party shall be obligated to pay the fees and
          expenses of such additional counsel or counsels.

                    5.6.4 Contribution. If for any reason the indemnification
          provided for in the preceding Section 5.6.1 or 5.6.2, as applicable,
          is unavailable to an indemnified party as contemplated by such
          Section, then the indemnifying party, in lieu of indemnification,
          shall contribute to the amount paid or payable by the indemnified
          party as a result of such 



                                       16
<PAGE>   17

          loss, claim, damage, liability or expense in such proportion as is
          appropriate to reflect not only the relative benefits received by the
          indemnified party and the indemnifying party, but also the relative
          fault of the indemnified party and the indemnifying party, as well as
          any other relevant equitable considerations; provided, however, that
          no selling Holder shall be required to contribute in an amount greater
          than the difference between the net proceeds received by the Holder
          with respect to the sale of Registrable Securities and all amounts
          already contributed by the Holder with respect to such claims,
          including amounts paid for any legal or other fees or expenses
          incurred by the Holder.

               5.7 Rule 144. The Company agrees that at all times after it has
filed a registration statement pursuant to the requirements of the Securities
Act relating to any class of equity securities of the Company, it will file in a
timely manner all reports required to be filed by it pursuant to the Securities
Act and the Securities Exchange Act of 1934, as amended (the "Exchange Act") and
will take such further action as any Holder may reasonably request in order that
such Holder may effect sales of Registrable Securities pursuant to Rule 144. At
any reasonable time and upon request of a Stockholder, the Company will furnish
such Stockholder and others with such information as may be necessary to enable
the Stockholder to effect sales of Common Stock pursuant to Rule 144 under the
Securities Act and will deliver to such Stockholder a written statement as to
whether it has complied with such requirements. Notwithstanding the foregoing,
the Company may deregister any class of its equity securities under Section 12
of the Exchange Act or suspend its duty to file reports with respect to any
class of its securities pursuant to Section 15(d) of the Exchange Act if it is
then permitted to do so pursuant to the Exchange Act and the rules and
regulations thereunder.

               5.8 Participation in Underwritten Registrations. No Holder may
participate in any underwritten registration hereunder unless such Holder (i)
agrees to sell its Registrable Securities on the basis provided in any
underwriting arrangements approved by the Company and (ii) accurately completes
in a timely manner and executes all questionnaires, powers of attorney,
underwriting agreements and other documents customarily required under the terms
of such underwriting arrangements.

               5.9 Registrable Securities. The term Registrable Securities shall
mean the Class A Common Stock of the Company; provided, however, that a
Registrable Security shall cease to be a Registrable Security at such time that
(i) the Registrable Security has been effectively registered under the
Securities Act and disposed of in accordance with the registration statement
covering it or (ii) has been sold to the public pursuant to Rule 144 (or any
similar provision then in force) under the Securities Act.

          6. Tag-Along Right.

               6.1 General Tag-Along Right. Prior to a Qualified Initial Public
Offering, and notwithstanding the fact that the Stockholders have approved an
Assignment pursuant to Section 4.1, a Stockholder (the "proposed transferor")
shall not transfer, sell, or otherwise dispose of more than 5% of its Class A
Common Stock or Class B Common Stock (collectively a "proposed tag-along
transfer") to a person (a "proposed tag-along purchaser") other than pursuant to
a Qualified Transfer or, in the case of KE, other than pursuant to a transfer to
an entity controlled 



                                       17
<PAGE>   18

by KE, in one transaction or a related series of transactions, unless the
proposed tag-along purchaser shall offer to each of the Stockholders that hold
Common Stock, whether or not of the same class, (a "Tag-Along Offer") the
opportunity to include in the proposed tag-along transfer the same percentage of
his or its Common Stock as that percentage of Common Stock proposed to be
transferred by the proposed transferor (based upon all outstanding Common Stock)
upon the same terms and conditions, and with the same price per share of Common
Stock, form of consideration and terms of payment offered by the proposed
tag-along purchaser to the proposed transferor (it being understood that Class A
Common Stock and Class B Common Stock shall be treated alike for purposes of
this Section 6.1). The proposed transferor shall, not less than 45 nor more than
90 days prior to the proposed tag-along transfer, notify, or cause to be
notified, each other Stockholder (the "Other Stockholder" or "Other
Stockholders") in writing of such proposed tag-along transfer (the "Tag-Along
Notice"). The Tag-Along Notice shall set forth: (i) the name of the proposed
transferor, the number and class or classes of Common Stock that the proposed
transferor proposes to transfer, and the percentage of his or its Common Stock
of that class or classes that the proposed transferor proposes to transfer and
the percentage of all outstanding Common Stock represented thereby; (ii) the
name of the proposed tag-along purchaser; (iii) the proposed amount and form of
consideration and terms and conditions of payment offered by the proposed
tag-along purchaser; and (iv) that the proposed tag-along purchaser has been
informed of the tag-along right provided for in this Section 6.1 and has agreed
to purchase such Common Stock in accordance with the terms hereof. The Tag-Along
Offer may be accepted by any Other Stockholder holding Common Stock, whether or
not of the same class as is subject to the proposed transfer, by delivery of a
written notice (the "Exercise Notice") to the proposed transferor within 15 days
following the date the Tag-Along Notice is given (the "Exercise Period"). The
Exercise Notice shall state the maximum number of shares of Common Stock that
such Other Stockholder proposes to include in the transfer to the proposed
tag-along purchaser, as determined herein. In the event the total number of
shares of Common Stock proposed to be sold to the proposed tag-along purchaser
by the proposed transferor and the Other Stockholders exceeds the number of
shares of Common Stock which the proposed tag-along purchaser is willing to
purchase, the number of shares of Common Stock to be sold by the proposed
transferor and the Other Stockholders shall be reduced pro rata based on the
total number of shares of Common Stock offered for sale by the proposed
transferor and each Other Stockholder. At the closing of the transfer to the
proposed tag-along purchaser (of which the proposed transferor shall give each
selling Other Stockholder at least 10 business days prior written notice), each
selling Other Stockholder shall (i) execute any documents or instruments,
including, without limitation, representations and warranties, reasonably
requested by the proposed tag-along purchaser (if any selling Other Stockholder
is unwilling to make such representations and warranties and/or related
indemnification as may be required by the proposed tag-along purchaser, such
Other Stockholder shall not have the tag-along right provided for in this
Section 6.1) and (ii) deliver certificates for the shares of Common Stock being
sold, duly endorsed or accompanied by duly executed Common Stock assignments
separate from certificate, free and clear of all claims and encumbrances,
against delivery by the proposed tag-along purchaser of the consideration for
the total sales price of the Common Stock of such Other Stockholders being sold
pursuant to this Section 6.1.

               6.2 Special Tag-Along Right. If, prior to a Qualified Initial
Public Offering, equity securities of any entity which is a "Controlled
Affiliate" of the "KU Control Group" (in each case as defined below) and which,
directly, or indirectly through its Controlled Affiliates, owns Common Stock (a
"Common Stock Owning KU Affiliate") are sold to any Person (other than a
Controlled Affiliate of the KU Control Group) and the total aggregate sales
price of such transfer, sale or other disposition of such equity securities in
such transaction or in a series of related transactions exceeds $10,000,000,
then the "Sibson Persons" (as that term is defined below) shall have the right
(the "Special Tag-Along Right") to have KE purchase a portion of their Common
Stock as set forth herein. If the $10,000,000 threshold is exceeded, then KE
shall within 10 days thereafter notify the Sibson Persons in writing (the
"Threshold Notice") of the details of such transaction and the percentage of
Common Stock (the "Applicable Percentage") indirectly transferred as a result of
such sale (based upon the percentage of equity ownership of the Common Stock
Owning KU Affiliate sold in the transaction and the number of shares of Common
Stock held, directly, or indirectly through one or more intermediaries, by such
Common Stock Owning KU Affiliate). The Sibson Persons shall have 30 days from
receipt of the Threshold Notice (which notice shall contain the calculation of
the Applicable Percentage and the details of how it was determined) to notify KE
in writing (the "Special Tag-Along Notice") that they desire to invoke the
Special Tag-Along Right. If any Sibson Person invokes the Special Tag-Along
Right, then such Sibson Person shall have the right to require KE and KE hereby
agrees to purchase a percentage of such Sibson Person's Common Stock in the
Company equal to the Applicable Percentage multiplied by the total percentage of
Common Stock in the Company held by such Sibson Person (with respect to any
Sibson Person, the "Sibson Percentage"). In determining the Sibson Percentage
the total number of shares of Common Stock held by such Sibson Person (including
for this purpose the number of shares of Common Stock for which there are
outstanding vested options held by such Sibson Person) shall be divided by the
total number of outstanding shares of Common Stock of the Company (including for
this purpose the number of shares of Common Stock for which there are
outstanding vested options held by all persons). For example, if the Applicable
Percentage is 20% and the Sibson Percentage is 5%, then the Special Tag-Along
Right shall apply to a number of shares of Common Stock (and shares of Common
Stock for which there are vested options) equal to 1.0% of the shares of Common
Stock (and for which there are vested options) of the Company, and such Sibson
Person shall have the right to require KE and, if the Special Tag-Along Right is
exercised, KE shall be obligated to purchase from him or it a number of shares
of Common Stock (and vested options) equal to 1.0% of the total number of shares
of Common Stock and vested options. The purchase price of shares of Common Stock
to be sold pursuant to the Special Tag-Along Right shall be determined in the
same manner as provided in Section 4.4. The purchase price of a vested option
(on a per share of Common Stock basis) shall be the purchase price of a share of
Common Stock, as determined above, less the strike price of such vested option.
For purposes of this provision, the term "Sibson Persons" shall mean any and all
of the following: those persons who received shares of Common Stock pursuant to
the Exchange Agreement, those persons who received shares of Common Stock
pursuant to their employment agreements with SC/NE, LLC or any subsidiary of
SC/NE, LLC, those persons who received options to purchase shares of Common
Stock of the Company pursuant to their employment with SC/NE, LLC, or any
subsidiary of SC/NE LLC, those persons who received Common Stock pursuant to
rights granted in that certain Share Purchase Agreement dated as of the date
hereof by and among Nextera, Sibson Acquisition Co. 



                                       19
<PAGE>   20

and the holders of all of the shares of Sibson Canada, Inc. and transferees of
such persons if pursuant to a Qualified Transfer. For purposes hereof, the "KU
Control Group" shall mean a group comprised of one or more of the three natural
persons who as of the date hereof beneficially own directly or indirectly the
majority of the capital stock of KE, and a "Controlled Affiliate" shall mean,
with respect to any Person, any Person controlled, directly or indirectly, by
such Person by ownership of voting securities, contract or otherwise.

          7. Sibson Board Representative. Until such time as both (i) the
percentage of the Company's consolidated net revenue generated by SC/NE, LLC
falls below 15% of the Company's total consolidated net revenue for any fiscal
year and (ii) the earnings before interest, taxes, depreciation and amortization
("EBITDA") generated by of SC/NE, LLC falls below 15% of the Company's total
consolidated EBITDA less corporate headquarters expense for any such fiscal year
(such event being the "Board Representation Termination Event"), the
Stockholders shall be required to elect the "Manager/SMP" of SC/NE, LLC, as that
term is defined in the Limited Liability Company Agreement of SC/NE, LLC dated
as of the date hereof, to the Board of Directors of the Company and each
Stockholder agrees to vote his Subject Shares to effectuate the same. Following
the Board Representation Termination Event, the Stockholders shall have no
obligation to elect the Manager/SMP of SC/NE, LLC to the Board.

          8. Certain Transactions. The Company shall not enter into any "Covered
Transaction" (as hereinafter defined) with any Affiliate without the prior
approval of a majority of the members of the Board of Directors of the Company
who are not (and have not been within the past five years) directly or
indirectly affiliated with such Affiliate, do not receive (and have not received
during the past five years) directly or indirectly any compensation from such
Affiliate (except for service as a director of the Company) and do not own (and
have not owned within the past five years) directly or indirectly any equity
interest in such Affiliate or any Affiliate of such Affiliate (other than the
Company). A "Covered Transaction" shall mean (i) any transaction or related
series of transactions between the Company or any subsidiary of the Company and
an Affiliate (including Affiliates of such Affiliate) which involves, in the
aggregate, a transaction sum in excess of $2,000,000 or (ii) any transaction
between the Company or any subsidiary of the Company and an Affiliate (including
Affiliates of such Affiliate) if such transaction, when taken together with all
other transactions between the Company and such Affiliate (including all
Affiliates of such Affiliate) during any period of 24 consecutive months,
involves, in the aggregate, a total transaction sum or value in excess of
$2,000,000.

          9. Further Assurances. Each Stockholder will, from time to time,
execute and deliver, or cause to be executed and delivered, such additional or
further consents, documents and other instruments as the Company may reasonably
request for the purpose of effectively carrying out the transactions
contemplated by this Agreement.

          10. Certain Events. Each Stockholder agrees that this Agreement and
the obligations hereunder shall attach to such Stockholder's Subject Shares and
shall be binding upon any person or entity to which legal or beneficial
ownership of such Subject Shares shall pass, whether by operation of law or
otherwise, including such Stockholder's heirs, guardians, administrators or
successors. In the event of any stock split, stock dividend, merger,
reorganization, recapitalization or other change in the capital structure of the
Company affecting the Common 



                                       20
<PAGE>   21

Stock, or the acquisition of additional shares of Common Stock or other voting
securities of the Company by any Stockholder, the number of Subject Shares
listed in Schedule A beside the name of such Stockholder shall be adjusted
appropriately and this Agreement and the obligations hereunder shall attach to
any additional shares of Common Stock or other voting securities of the Company
issued to or acquired by such Stockholder.

          11. Assignment. Except in connection with an Assignment specifically
permitted by Section 4, neither this Agreement nor any of the rights, interests
or obligations hereunder shall be assigned by any Stockholder without the prior
written consent of the Company. Subject to the preceding sentence, this
Agreement will be binding upon, inure to the benefit of and be enforceable by
the parties and their respective successors and assigns.

          12. General Provisions.

               12.1 Amendments. This Agreement may not be amended except by an
instrument in writing signed by Nextera or the Company, Stockholders holding a
majority of the Subject Shares and Stockholders holding a majority of the
Subject Shares held by Sibson Persons.

               12.2 Notice. All notices and other communications hereunder shall
be in writing and shall be deemed given if delivered personally or sent by
overnight courier (providing proof of delivery) to Nextera or the Company, One
Cranberry Hill, Lexington, Massachusetts, Attention: President and to the
Stockholders at their respective addresses set forth on the records of the
Company, until such time as Schedule A is attached hereto when completed as
described in Section 16 below, and thereafter to the Stockholders at their
respective addresses set forth thereon (or at such other address for a party as
shall be specified in like notice).

               12.3 Interpretation. When a reference is made in this Agreement
to Sections, such reference shall be to a Section to this Agreement unless
otherwise indicated. The headings contained in this Agreement are for reference
purposes only and shall not affect in any way the meaning or interpretation of
this Agreement. Wherever the words "include," "includes" or "including" are used
in this Agreement, they shall be deemed to be followed by the words "without
limitation."

               12.4 Counterparts. This Agreement may be executed in one or more
counterparts, all of which shall be considered one and the same agreement, and
shall become effective when one or more of the counterparts have been signed by
each of the parties and delivered to the other party, it being understood that
each party need not sign the same counterpart.

               12.5 Entire Agreement; No Third-Party Beneficiaries. This
Agreement (including the documents and instruments referred to herein) (i)
constitutes the entire agreement and supersedes all prior agreements and
understandings, both written and oral, among the parties with respect to the
subject matter hereof and (ii) is not intended to confer upon any person other
than the parties hereto any rights or remedies hereunder.



                                       21
<PAGE>   22

               12.6 Governing Law. This Agreement shall be governed by, and
construed in accordance with, the laws of the State of Delaware regardless of
the laws that might otherwise govern under applicable principles of conflicts of
law thereof.

          13. Enforceable. The parties agree that irreparable damage would occur
in the event that any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached. It is
accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent breaches of this Agreement and to enforce specifically
the terms and provisions of this Agreement this being in addition to any other
remedy to which they are entitled at law or in equity.

          14. Public Announcements. Except as otherwise specifically provided in

Nextera, SC/NE, LLC, Sibson & Company, L.P., Sibson & Company, Inc., SC2, Inc.

shall issue any press release or other public statement with respect to the
transactions contemplated by this Agreement and the documents implementing the
Incorporation Transaction without the prior written consent of Nextera, except
as required by law.

          15. Severability. If any term or other provision of this Agreement is
invalid, illegal or incapable of being enforced by any rule or law or public
policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible to the fullest extent
permitted by applicable law in an acceptable manner to the end that the
transactions contemplated hereby are fulfilled to the extent possible.

          16. Schedule A. As soon as practical, but in no event later than ten
business days prior to the completion of the Incorporation Transaction (subject
to further updates through the Incorporation Transaction), Nextera agrees to
update and complete Schedule A hereto, including the number of shares of Class A
Common Stock and Class B Common Stock held by, and the address of, each
Stockholder and cause a copy thereof certified as being true and correct by
officers of each of the Company and Nextera to be delivered to the Stockholders
for attachment to this Agreement.

the Incorporation Transaction it shall adopt the Amended and Restated
Certificate of Incorporation and By-laws in substantially the forms attached as
Exhibit A-1 and Exhibit A-2 hereto, with any changes thereto as will not
materially adversely affect the rights of the Stockholders hereunder and

Incorporation Transaction, the Company and the Stockholders shall take all steps
reasonably necessary and appropriate from time to time to assure that the
Constituent Documents, to the extent permitted under applicable law, do not
conflict with the terms and provisions of this Agreement and that the rights of
holders of Class A Common Stock are identical to rights of holders of Class B
Common Stock (except for (i) holders of shares of Class A Common Stock being
entitled to ten votes per 



                                       22

share and (ii) that shares of Class B Common Stock will convert into shares of

               (b) indictment of the Optionee for (i) a felony or (ii) any
          misdemeanor involving moral turpitude, deceit, dishonesty or fraud
          ("indictment," for these purposes, meaning an indictment, probable
          cause hearing or any other procedure pursuant to which an initial
          determination of probable or reasonable cause with respect to such
          offense is made);

               (c) willful misconduct by the Optionee after three (3) days
          written notice and an opportunity to cure;

               (d) gross negligence, or willful failure or refusal of the
          Optionee to comply with explicit directions of the Board after fifteen
          (15) days written notice and an opportunity to cure.

          In making any determination under this Section 1.38 the Board shall
act fairly and in good faith and shall give the Optionee an opportunity to
appear and be heard at a meeting of the Board or any committee thereof and
present evidence on his behalf.

          1.39. Termination of Consultancy. "Termination of Consultancy" shall
mean the time when the engagement of a Holder as a Consultant to the Company or
a Subsidiary is terminated for any reason, with or without cause, including, but
not by way of limitation, by resignation, discharge, death or retirement; but
excluding terminations where there is a simultaneous commencement of employment
with the Company or any Subsidiary. The Administrator, in its absolute
discretion, shall determine the effect of all matters and questions relating to
Termination of Consultancy, including, but not by way of limitation, the
question of whether a Termination of Consultancy resulted from a discharge for
good cause, and all questions of whether a particular leave of absence
constitutes a Termination of Consultancy. Notwithstanding any other provision of
the Plan, the Company or any Subsidiary has an absolute and unrestricted right
to terminate a Consultant's service at any time for any reason whatsoever, with
or without cause, except to the extent expressly provided otherwise in writing.

          1.40. Termination of Directorship. "Termination of Directorship" shall
mean the time when a Holder who is an Independent Director ceases to be a
Director for any reason, including, but not by way of limitation, a termination
by resignation, failure to be elected, death or retirement. The Board, in its
sole and absolute discretion, shall determine the effect of all matters and
questions relating to Termination of Directorship with respect to Independent
Directors.

          1.41. Termination of Employment. "Termination of Employment" shall
mean the time when the employee-employer relationship between a Holder and the
Company or any Subsidiary is terminated for any reason, with or without cause,
including, but not by way of limitation, a termination by resignation,
discharge, death, Disability or retirement; but excluding (a) terminations where
there is a simultaneous reemployment or continuing employment of a Holder by the
Company or any Subsidiary, (b) at the discretion of the Administrator,
terminations which result in a temporary severance of the employee-employer
relationship, and (c) at the discretion of the Administrator, terminations which
are followed by the simultaneous establishment of a consulting relationship by
the Company or a Subsidiary with the former employee. The Administrator, in its
absolute discretion, shall determine the effect of all matters and questions
relating to Termination of Employment, including, but not by way of limitation,
the question of whether a Termination of Employment resulted from a discharge
for good cause, and all questions of whether a particular leave of absence
constitutes a Termination of Employment; provided, however, that, with respect
to Incentive Stock Options, unless otherwise determined by the Administrator in
its discretion, a leave of absence, change in status from an employee to an
independent contractor or other change in the employee-employer relationship
shall constitute a Termination of Employment if, and to the extent that, such
leave of absence, change in status or other change interrupts employment for the
purposes of Section 422(a)(2) of the Code and the then applicable regulations
and revenue rulings under said Section.

                                   ARTICLE II.

                             SHARES SUBJECT TO PLAN

          2.1. Shares Subject to Plan.

               (a) The shares of stock subject to Awards shall be Class A Common
          Stock, initially shares of the Company's Class A Common Stock, par
          value $ 0.001 per share. The aggregate number of such shares which may
          be issued upon exercise of such Options or rights or upon any such
          awards under the Plan shall not exceed _______________ (___________).
          The shares of Class A Common Stock issuable upon exercise of such
          Options or rights or upon any such awards may be either previously
          authorized but unissued shares or treasury shares.

               (b) The maximum number of shares which may be subject to Awards,
          granted under the Plan to any individual in any calendar year shall
          not exceed the Award Limit. To the extent required by Section 162(m)
          of the Code, shares subject to Options which are canceled continue to
          be counted against the Award Limit.

          2.2. Add-back of Options and Other Rights. If any Option, or other
right to acquire shares of Class A Common Stock under any other Award under the
Plan, expires or is canceled without having been fully exercised, or is
exercised in whole or in part for cash as permitted by the Plan, the number of
shares subject to such Option or other right but as to which such Option or
other right was not exercised prior to its expiration, cancellation or exercise
may again be optioned, granted or awarded hereunder, subject to the limitations
of Section 2.1. Furthermore, any shares subject to Awards which are adjusted
pursuant to Section 11.3 and 



                                       7
<PAGE>   8

become exercisable with respect to shares of stock of another corporation shall
be considered canceled and may again be optioned, granted or awarded hereunder,
subject to the limitations of Section 2.1. Shares of Class A Common Stock which
are delivered by the Holder or withheld by the Company upon the exercise of any
Award under the Plan, in payment of the exercise price thereof or tax
withholding thereon, may again be optioned, granted or awarded hereunder,
subject to the limitations of Section 2.1. If any shares of Restricted Stock are
surrendered by the Holder or repurchased by the Company pursuant to Section 7.4
or 7.5 hereof, such shares may again be optioned, granted or awarded hereunder,
subject to the limitations of Section 2.1. Notwithstanding the provisions of
this Section 2.2, no shares of Class A Common Stock may again be optioned,
granted or awarded if such action would cause an Incentive Stock Option to fail
to qualify as an incentive stock option under Section 422 of the Code.

                                  ARTICLE III.

                               GRANTING OF AWARDS

          3.1. Award Agreement. Each Award shall be evidenced by an Award
Agreement. Award Agreements evidencing Awards intended to qualify as
performance-based compensation as described in Section 162(m)(4)(C) of the Code
shall contain such terms and conditions as may be necessary to meet the
applicable provisions of Section 162(m) of the Code. Award Agreements evidencing
Incentive Stock Options shall contain such terms and conditions as may be
necessary to meet the applicable provisions of Section 422 of the Code.

          3.2. Provisions Applicable to Section 162(m) Participants.

               (a) The Committee, in its discretion, may determine whether an
          Award is to qualify as performance-based compensation as described in
          Section 162(m)(4)(C) of the Code.

               (b) Notwithstanding anything in the Plan to the contrary, the
          Committee may grant any Award to a Section 162(m) Participant,
          including Restricted Stock the restrictions with respect to which
          lapse upon the attainment of performance goals which are related to
          one or more of the Performance Criteria and any performance or
          incentive award described in Article VIII that vests or becomes
          exercisable or payable upon the attainment of performance goals which
          are related to one or more of the Performance Criteria.

               (c) To the extent necessary to comply with the performance-based
          compensation requirements of Section 162(m)(4)(C) of the Code, with
          respect to any Award granted under Articles VII and VIII which may be
          granted to one or more Section 162(m) Participants, no later than
          ninety (90) days following the commencement of any fiscal year in
          question or any other designated fiscal period or period of service
          (or such other time as may be required or permitted by Section 162(m)
          of the Code), the Committee shall, in writing, (i) designate one or
          more Section 162(m) Participants, (ii) select the Performance Criteria
          applicable to the fiscal year or other designated fiscal period or
          period of service, (iii) establish the various performance targets, in
          terms of an 



                                       8
<PAGE>   9

          objective formula or standard, and amounts of such Awards, as
          applicable, which may be earned for such fiscal year or other
          designated fiscal period or period of service and (iv) specify the
          relationship between Performance Criteria and the performance targets
          and the amounts of such Awards, as applicable, to be earned by each
          Section 162(m) Participant for such fiscal year or other designated
          fiscal period or period of service. Following the completion of each
          fiscal year or other designated fiscal period or period of service,
          the Committee shall certify in writing whether the applicable
          performance targets have been achieved for such fiscal year or other
          designated fiscal period or period of service. In determining the
          amount earned by a Section 162(m) Participant, the Committee shall
          have the right to reduce (but not to increase) the amount payable at a
          given level of performance to take into account additional factors
          that the Committee may deem relevant to the assessment of individual
          or corporate performance for the fiscal year or other designated
          fiscal period or period of service.

               (d) Furthermore, notwithstanding any other provision of the Plan
          or any Award which is granted to a Section 162(m) Participant and is
          intended to qualify as performance-based compensation as described in
          Section 162(m)(4)(C) of the Code shall be subject to any additional
          limitations set forth in Section 162(m) of the Code (including any
          amendment to Section 162(m) of the Code) or any regulations or rulings
          issued thereunder that are requirements for qualification as
          performance-based compensation as described in Section 162(m)(4)(C) of
          the Code, and the Plan shall be deemed amended to the extent necessary
          to conform to such requirements.

          3.3. Limitations Applicable to Section 16 Persons. Notwithstanding any
other provision of the Plan, the Plan, and any Award granted or awarded to any
individual who is then subject to Section 16 of the Exchange Act, shall be
subject to any additional limitations set forth in any applicable exemptive rule
under Section 16 of the Exchange Act (including any amendment to Rule 16b-3 of
the Exchange Act) that are requirements for the application of such exemptive
rule. To the extent permitted by applicable law, the Plan and Awards granted or
awarded hereunder shall be deemed amended to the extent necessary to conform to
such applicable exemptive rule.

          3.4. Consideration. In consideration of the granting of an Award under
the Plan, the Holder shall agree, in the Award Agreement, to render faithful and
efficient services to the Company or a Subsidiary.

          3.5. At-Will Employment. Nothing in the Plan or in any Award Agreement
hereunder shall confer upon any Holder any right to continue in the employ of,
or as a Consultant for, the Company or any Subsidiary, or as a director of the
Company, or shall interfere with or restrict in any way the rights of the
Company and any Subsidiary, which are hereby expressly reserved, to discharge
any Holder at any time for any reason whatsoever, with or without cause, except
to the extent expressly provided otherwise in a written employment agreement
between the Holder and the Company and any Subsidiary.

                                   ARTICLE IV.

                        GRANTING OF OPTIONS TO EMPLOYEES,
                      CONSULTANTS AND INDEPENDENT DIRECTORS

          4.1. Eligibility. Any Employee or Consultant selected by the Committee
pursuant to Section 4.4(a)(i) shall be eligible to be granted an Option. Each
Independent Director of the Company shall be eligible to be granted Options at
the times and in the manner set forth in Section 4.5.

          4.2. Disqualification for Stock Ownership. No person may be granted an
Incentive Stock Option under the Plan if such person, at the time the Incentive
Stock Option is granted, owns stock possessing more than ten percent (10%) of
the total combined voting power of all classes of stock of the Company or any
then existing Subsidiary or parent corporation (within the meaning of Section
422 of the Code) unless such Incentive Stock Option conforms to the applicable
provisions of Section 422 of the Code.

          4.3. Qualification of Incentive Stock Options. No Incentive Stock
Option shall be granted to any person who is not an Employee.

          4.4. Granting of Options to Employees and Consultants.

               (a) The Committee shall from time to time, in its absolute
          discretion, and subject to applicable limitations of the Plan:

                    (i) Determine which Employees are key Employees and select
          from among the key Employees or Consultants (including Employees or
          Consultants who have previously received Awards under the Plan) such
          of them as in its opinion should be granted Options;

                    (ii) Subject to the Award Limit, determine the number of
          shares to be subject to such Options granted to the selected key
          Employees or Consultants;

                    (iii) Subject to Section 4.3, determine whether such Options
          are to be Incentive Stock Options or Non-Qualified Stock Options and
          whether such Options are to qualify as performance-based compensation
          as described in Section 162(m)(4)(C) of the Code; and

                    (iv) Determine the terms and conditions of such Options,
          consistent with the Plan; provided, however, that the terms and
          conditions of Options intended to qualify as performance-based
          compensation as described in Section 162(m)(4)(C) of the Code shall
          include, but not be limited to, such terms and conditions as may be
          necessary to meet the applicable provisions of Section 162(m) of the
          Code.

               (a) Upon the selection of a key Employee or Consultant to be
          granted an Option, the Committee shall instruct the Secretary of the
          Company to issue the Option and may impose such conditions on the
          grant of the Option as it deems appropriate.



                                       10
<PAGE>   11

               (b) Any Incentive Stock Option granted under the Plan may be
          modified by the Committee, with the consent of the Holder, to
          disqualify such Option from treatment as an "incentive stock option"
          under Section 422 of the Code.

          4.5. Granting of Options to Independent Directors.

               The Board shall from time to time, in its absolute discretion,
and subject to applicable limitations of the Plan:

               (a) Select from among the Independent Directors (including
          Independent Directors who have previously received Options under the
          Plan) such of them as in its opinion should be granted Options;

               (b) Subject to the Award Limit, determine the number of shares to
          be subject to such Options granted to the selected Independent
          Directors;

               (c) Subject to the provisions of Article 5, determine the terms
          and conditions of such Options, consistent with the Plan.

          All the foregoing Option grants authorized by this Section 4.5 are
subject to stockholder approval of the Plan.

                                   ARTICLE V.

                                TERMS OF OPTIONS

          5.1. Option Price. The price per share of the shares subject to each
Option granted to Employees and Consultants shall be set by the Committee;
provided, however, that such price shall be no less than the par value of a
share of Class A Common Stock, unless otherwise permitted by applicable state
law and:

               (a) in the case of Options intended to qualify as
          performance-based compensation as described in Section 162(m)(4)(C) of
          the Code, such price shall not be less than 100% of the Fair Market
          Value of a share of Class A Common Stock on the date the Option is
          granted;

               (b) in the case of Incentive Stock Options such price shall not
          be less than 100% of the Fair Market Value of a share of Class A
          Common Stock on the date the Option is granted (or the date the Option
          is modified, extended or renewed for purposes of Section 424(h) of the
          Code);

               (c) in the case of Incentive Stock Options granted to an
          individual then owning (within the meaning of Section 424(d) of the
          Code) more than 10% of the total combined voting power of all classes
          of stock of the Company or any Subsidiary or parent corporation
          thereof (within the meaning of Section 422 of the Code), such price
          shall not be less than 110% of the Fair Market Value of a share of
          Class A Common Stock on the 



                                       11
<PAGE>   12

          date the Option is granted (or the date the Option is modified,
          extended or renewed for purposes of Section 424(h) of the Code).

          5.2. Option Term. The term of an Option granted to an Employee or
Consultant shall be set by the Committee in its discretion; provided, however,
that:

               (a) No Option may have a term that extends beyond the expiration
          of ten (10) years from the date the Option was granted;

               (b) In the case of Incentive Stock Options, the term shall not be
          more than ten (10) years from the date the Incentive Stock Option is
          granted, or five (5) years from such date if the Incentive Stock
          Option is granted to an individual then owning (within the meaning of
          Section 424(d) of the Code) more than ten percent (10%) of the total
          combined voting power of all classes of equity of the Company or any
          Subsidiary;

               (c) Except as limited by requirements of Section 422 of the Code
          and regulations and rulings thereunder applicable to Incentive Stock
          Options, the Committee (or the Board in the case of Options granted to
          Independent Directors) may extend the term of any outstanding Option
          in connection with any Termination of Directorship, Termination of
          Employment or Termination of Consultancy of the Optionee, or amend any
          other term or condition of such Option relating to such a termination;
          and

               (d) Unless otherwise permitted by applicable securities laws, in
          the event of an Optionee's Termination of Directorship, Termination of
          Employment or Termination of Consultancy for any reason except death,
          Disability or Termination for Cause, the Optionee shall have at least
          ninety (90) days from the date of such Termination of Directorship,
          Termination of Employment or Termination of Consultancy to exercise
          the Option, and in the event of an Optionee's Termination of
          Directorship, Termination of Employment or Termination of Consultancy
          due to the Optionee's death or Disability, the Optionee shall have at
          least one hundred eighty (180) days from the date of such Termination
          of Directorship, Termination of Employment or Termination of
          Consultancy to exercise the Option. Notwithstanding the forgoing, if
          an Optionee's Termination of Directorship, Termination of Employment
          or Termination of Consultancy also qualifies as a Termination for
          Cause, the Company, in its discretion, may terminate the Optionee's
          right to exercise his or her Options on the date of such termination
          or such other time as the Committee (or the Board in the case of
          Options granted to Independent Directors), in its discretion, shall
          deem appropriate.

          5.3. Option Vesting

               (a) The period during which the right to exercise, in whole or in
          part, an Option granted to an Employee or a Consultant vests in the
          Holder shall be set by the Committee and the Committee may determine
          that an Option may not be exercised in whole or in part for a
          specified period after it is granted; provided, however, that, unless
          the Committee otherwise provides in the terms of the Award Agreement
          or otherwise, no Option shall be exercisable by any Holder who is then
          subject to Section 16 of the 



                                       12
<PAGE>   13

          Exchange Act within the period ending six months and one day after the
          date the Option is granted. At any time after grant of an Option, the
          Committee may, in its sole and absolute discretion and subject to
          whatever terms and conditions it selects, accelerate the period during
          which an Option granted to an Employee or Consultant vests.

               (b) No portion of an Option granted to an Employee or Consultant
          which is unexercisable at Termination of Employment or Termination of
          Constancy, as applicable, shall thereafter become exercisable, except
          as may be otherwise provided by the Committee either in the Award
          Agreement or by action of the Committee following the grant of the
          Option; provided, however that if an Optionee's employment, in the
          case of an Employee, or provision of services, in the case of a
          Consultant, terminated by reason of death or Disability, the Option
          shall become exercisable with respect to one-hundred percent (100% of
          the Class A Common Units subject to such Option.

               (c) To the extent that the aggregate Fair Market Value of stock
          with respect to which "incentive stock options" (within the meaning of
          Section 422 of the Code, but without regard to Section 422(d) of the
          Code) are exercisable for the first time by a Holder during any
          calendar year (under the Plan and all other incentive stock option
          plans of the Company and any parent or subsidiary corporation, within
          the meaning of Section 422 of the Code) of the Company, exceeds
          $100,000, such Options shall be treated as Non-Qualified Options to
          the extent required by Section 422 of the Code. The rule set forth in
          the preceding sentence shall be applied by taking Options into account
          in the order in which they were granted. For purposes of this Section
          5.3(c), the Fair Market Value of stock shall be determined as of the
          time the Option with respect to such stock is granted.

          5.4. Terms of Options Granted to Independent Directors. The price per
share of the shares subject to each Option granted to an Independent Director
shall equal 100% of the Fair Market Value of a share of Class A Common Stock on
the date the Option is granted. Options granted to Independent Directors shall
become exercisable in cumulative annual installments of 25% on each of the
first, second, third and fourth anniversaries of the date of Option grant and,
subject to Section 6.6, the term of each Option granted to an Independent
Director shall be ten (10) years from the date the Option is granted. No portion
of an Option which is unexercisable at Termination of Directorship shall
thereafter become exercisable.

          5.5. Substitute Awards. Notwithstanding the foregoing provisions of
this Article V to the contrary, in the case of an Option that is a Substitute
Award, the price per share of the shares subject to such Option may be less than
the Fair Market Value per share on the date of grant, provided, that the excess
of:

               (a) the aggregate Fair Market Value (as of the date such
          Substitute Award is granted) of the shares subject to the Substitute
          Award; over

               (b) the aggregate exercise price thereof; does not exceed the
          excess of;



                                       13
<PAGE>   14

               (c) the aggregate fair market value (as of the time immediately
          preceding the transaction giving rise to the Substitute Award, such
          fair market value to be determined by the Committee) of the shares of
          the predecessor entity that were subject to the grant assumed or
          substituted for by the Company; over

               (d) the aggregate exercise price of such shares.

                                   ARTICLE VI.

                               EXERCISE OF OPTIONS

          6.1. Partial Exercise. An exercisable Option may be exercised in whole
or in part. However, an Option shall not be exercisable with respect to
fractional shares and the Administrator may require that, by the terms of the
Option, a partial exercise be with respect to a minimum number of shares.

          6.2. Manner of Exercise. All or a portion of an exercisable Option
shall be deemed exercised upon delivery of all of the following to the Secretary
of the Company or his office:

               (a) A written notice complying with the applicable rules
          established by the Administrator stating that the Option, or a portion
          thereof, is exercised. The notice shall be signed by the Holder or
          other person then entitled to exercise the Option or such portion of
          the Option;

               (b) Such representations and documents as the Administrator, in
          its absolute discretion, deems necessary or advisable to effect
          compliance with all applicable provisions of the Securities Act and
          any other federal or state securities laws or regulations. The
          Administrator may, in its absolute discretion, also take whatever
          additional actions it deems appropriate to effect such compliance
          including, without limitation, placing legends on share certificates
          and issuing stop-transfer notices to agents and registrars;

               (c) In the event that the Option shall be exercised pursuant to
          Section 11.1 by any person or persons other than the Holder,
          appropriate proof of the right of such person or persons to exercise
          the Option; and

               (d) Full cash payment to the Secretary of the Company for the
          shares with respect to which the Option, or portion thereof, is
          exercised. However, the Administrator, may in its discretion (i) allow
          a delay in payment up to thirty (30) days from the date the Option, or
          portion thereof, is exercised; (ii) allow payment, in whole or in
          part, through the delivery of shares of Class A Common Stock which
          have been owned by the Holder for at least six months, duly endorsed
          for transfer to the Company with a Fair Market Value on the date of
          delivery equal to the aggregate exercise price of the Option or
          exercised portion thereof; (iii) allow payment, in whole or in part,
          through the surrender of shares of Class A Common Stock then issuable
          upon exercise of the Option having a Fair Market Value on the date of
          Option exercise equal to the aggregate exercise




                                       14
<PAGE>   15

          price of the Option or exercised portion thereof; (iv) allow payment,
          in whole or in part, through the delivery of a full recourse
          promissory note bearing interest (at no less than such rate as shall
          then preclude the imputation of interest under the Code) and payable
          upon such terms as may be prescribed by the Administrator; (v) allow
          payment, in whole or in part, through the delivery of a notice that
          the Holder has placed a market sell order with a broker with respect
          to shares of Class A Common Stock then issuable upon exercise of the
          Option, and that the broker has been directed to pay a sufficient
          portion of the net proceeds of the sale to the Company in satisfaction
          of the Option exercise price, provided that payment of such proceeds
          is then made to the Company upon settlement of such sale; or (vii)
          allow payment through any combination of the consideration provided in
          the foregoing subparagraphs (ii), (iii), (iv), and (v). In the case of
          a promissory note, the Administrator may also prescribe the form of
          such note and the security to be given for such note. The Option may
          not be exercised, however, by delivery of a promissory note or by a
          loan from the Company when or where such loan or other extension of
          credit is prohibited by law.

          6.3. Conditions to Issuance of Stock Certificates. The Company shall
not be required to issue or deliver any certificate or certificates for shares
of stock purchased upon the exercise of any Option or portion thereof prior to
fulfillment of all of the following conditions:

               (a) The admission of such shares to listing on all stock
          exchanges on which such class of stock is then listed;

               (b) The completion of any registration or other qualification of
          such shares under any state or federal law, or under the rulings or
          regulations of the Securities and Exchange Commission or any other
          governmental regulatory body which the Administrator shall, in its
          absolute discretion, deem necessary or advisable;

               (c) The obtaining of any approval or other clearance from any
          state or federal governmental agency which the Administrator shall, in
          its absolute discretion, determine to be necessary or advisable;

               (d) The lapse of such reasonable period of time following the
          exercise of the Option as the Administrator may establish from time to
          time for reasons of administrative convenience; and

               (e) The receipt by the Company of full payment for such shares,
          including payment of any applicable withholding tax, which in the
          discretion of the Administrator may be in the form of consideration
          used by the Holder to pay for such shares under Section 6.2(d).

          6.4. Rights as Stockholders. Holders shall not be, nor have any of the
rights or privileges of, stockholders of the Company in respect of any shares
purchasable upon the exercise of any part of an Option unless and until
certificates representing such shares have been issued by the Company to such
Holders.



                                       15
<PAGE>   16

          6.5. Ownership and Transfer Restrictions. The Administrator, in its
absolute discretion, may impose such restrictions on the ownership and
transferability of the shares purchasable upon the exercise of an Option as it
deems appropriate. Any such restriction shall be set forth in the respective
Award Agreement and may be referred to on the certificates evidencing such
shares. The Holder shall give the Company prompt notice of any disposition of
shares of Class A Common Stock acquired by exercise of an Incentive Stock Option
within (a) two years from the date of granting (including the date the Option is
modified, extended or renewed for purposes of Section 424(h) of the Code) such
Option to such Holder or (b) one year after the transfer of such shares to such
Holder.

          6.6. Limitations on Exercise of Options Granted to Independent
Directors. No Option granted to an Independent Director may be exercised to any
extent by anyone after the first to occur of the following events:

               (a) the expiration of twelve (12) months from the date of the
          Holder's death;

               (b) the expiration of twelve (12) months from the date of the
          Holder's Termination of Directorship by reason of his Disability;

               (c) the expiration of three (3) months from the date of the
          Holder's Termination of Directorship for any reason other than such
          Holder's death or his Disability, unless the Holder dies within said
          three-month period; or

               (d) the expiration of ten (10) years from the date the Option was
          granted.

          6.7. Additional Limitations on Exercise of Options. Holders may be
required to comply with any timing or other restrictions with respect to the
settlement or exercise of an Option, including a window-period limitation, as
may be imposed in the discretion of the Administrator.

                                  ARTICLE VII.

                            AWARD OF RESTRICTED STOCK

          7.1. Eligibility. Subject to the Award Limit, Restricted Stock may be
awarded to any Employee who the Committee determines is a key Employee or any
Consultant who the Committee determines should receive such an Award.

          7.2. Award of Restricted Stock

               (a) The Committee may from time to time, in its absolute
          discretion:

                    (i) Determine which Employees are key Employees and select
          from among the key Employees or Consultants (including Employees 



                                       16
<PAGE>   17

          or Consultants who have previously received other awards under the
          Plan) such of them as in its opinion should be awarded Restricted
          Stock; and

                    (ii) Determine the purchase price, if any, and other terms
          and conditions applicable to such Restricted Stock, consistent with
          the Plan.

               (b) The Committee shall establish the purchase price, if any, and
          form of payment for Restricted Stock; provided, however, that such
          purchase price shall be no less than the par value of the Class A
          Common Stock to be purchased, unless otherwise permitted by applicable
          state law. In all cases, legal consideration shall be required for
          each issuance of Restricted Stock.

               (c) Upon the selection of a key Employee or Consultant to be
          awarded Restricted Stock, the Committee shall instruct the Secretary
          of the Company to issue such Restricted Stock and may impose such
          conditions on the issuance of such Restricted Stock as it deems
          appropriate.

          7.3. Rights as Stockholders. Subject to Section 7.4, upon delivery of
the shares of Restricted Stock to the escrow holder pursuant to Section 7.6, the
Holder shall have, unless otherwise provided by the Committee, all the rights of
a stockholder with respect to said shares, subject to the restrictions in his
Award Agreement, including the right to receive all dividends and other
distributions paid or made with respect to the shares; provided, however, that
in the discretion of the Committee, any extraordinary distributions with respect
to the Class A Common Stock shall be subject to the restrictions set forth in
Section 7.4.

          7.4. Restriction. All shares of Restricted Stock issued under the Plan
(including any shares received by holders thereof with respect to shares of
Restricted Stock as a result of stock dividends, stock splits or any other form
of recapitalization) shall, in the terms of each individual Award Agreement, be
subject to such restrictions as the Committee shall provide, which restrictions
may include, without limitation, restrictions concerning voting rights and
transferability and restrictions based on duration of employment with the
Company, Company performance and individual performance; provided, however,
that, unless the Committee otherwise provides in the terms of the Award
Agreement or otherwise, no share of Restricted Stock granted to a person subject
to Section 16 of the Exchange Act shall be sold, assigned or otherwise
transferred until at least six months and one day have elapsed from the date on
which the Restricted Stock was issued, and provided, further,] that, except with
respect to shares of Restricted Stock granted to Section 162(m) Participants, by
action taken after the Restricted Stock is issued, the Committee may, on such
terms and conditions as it may determine to be appropriate, remove any or all of
the restrictions imposed by the terms of the Award Agreement. Restricted Stock
may not be sold or encumbered until all restrictions are terminated or expire.
If no consideration was paid by the Holder upon issuance, a Holder's rights in
unvested Restricted Stock shall lapse, and such Restricted Stock shall be
surrendered to the Company without consideration, upon Termination of 
Employment or, if applicable, upon Termination of Consultancy with the Company;
provided, however, that the Committee in its sole and absolute discretion may
provide that such rights shall not lapse in the event of a Termination of



                                       17
<PAGE>   18

Employment following a "change of ownership or control" (within the meaning of
Treasury Regulation Section 1.162-27(e)(2)(v) or any successor regulation
thereto) of the Company or because of the Holder's death or Disability;
provided, further, except with respect to shares of Restricted Stock granted to
Section 162(m) Participants, the Committee in its sole and absolute discretion
may provide that no such lapse or surrender shall occur in the event of a
Termination of Employment, or a Termination of Consultancy, without cause or
following any Change in Control of the Company or because of the Holder's
retirement, or otherwise.

          7.5. Repurchase of Restricted Stock. The Committee shall provide in
the terms of each individual Award Agreement that the Company shall have the
right to repurchase from the Holder the Restricted Stock then subject to
restrictions under the Award Agreement immediately upon a Termination of
Employment or, if applicable, upon a Termination of Consultancy between the
Holder and the Company, at a cash price per share equal to the price paid by the
Holder for such Restricted Stock; provided, however, that the Committee in its
sole and absolute discretion may provide that no such right of repurchase shall
exist in the event of a Termination of Employment following a "change of
ownership or control" (within the meaning of Treasury Regulation Section
1.162-27(e)(2)(v) or any successor regulation thereto) of the Company or because
of the Holder's death or Disability; provided, further, that, except with
respect to shares of Restricted Stock granted to Section 162(m) Participants,
the Committee in its sole and absolute discretion may provide that no such right
of repurchase shall exist in the event of a Termination of Employment or a
Termination of Consultancy without cause or following any Change in Control of
the Company or because of the Holder's retirement, or otherwise.

          7.6. Escrow. The Secretary of the Company or such other escrow holder
as the Committee may appoint shall retain physical custody of each certificate
representing Restricted Stock until all of the restrictions imposed under the
Award Agreement with respect to the shares evidenced by such certificate expire
or shall have been removed.

          7.7. Legend. In order to enforce the restrictions imposed upon shares
of Restricted Stock hereunder, the Committee shall cause a legend or legends to
be placed on certificates representing all shares of Restricted Stock that are
still subject to restrictions under Award Agreements, which legend or legends
shall make appropriate reference to the conditions imposed thereby.

          7.8. Section 83(b) Election. If a Holder makes an election under
Section 83(b) of the Code, or any successor section thereto, to be taxed with
respect to the Restricted Stock as of the date of transfer of the Restricted
Stock rather than as of the date or dates upon which the Holder would otherwise
be taxable under Section 83(a) of the Code, the Holder shall deliver a copy of
such election to the Company immediately after filing such election with the
Internal Revenue Service.

<PAGE>   19

          8.1. Eligibility. Subject to the Award Limit, one or more Performance
Awards, Dividend Equivalents, awards of Deferred Stock, and/or Stock Payments
may be granted to any Employee whom the Committee determines is a key Employee
or any Consultant whom the Committee determines should receive such an Award.

          8.2. Performance Awards. Any key Employee or Consultant selected by
the Committee may be granted one or more Performance Awards. The value of such
Performance Awards may be linked to any one or more of the Performance Criteria
or other specific performance criteria determined appropriate by the Committee,
in each case on a specified date or dates or over any period or periods
determined by the Committee. In making such determinations, the Committee shall
consider (among such other factors as it deems relevant in light of the specific
type of award) the contributions, responsibilities and other compensation of the
particular key Employee or Consultant.

          8.3. Dividend Equivalents.

               (a) Any key Employee or Consultant selected by the Committee may
          be granted Dividend Equivalents based on the dividends declared on
          Class A Common Stock, to be credited as of dividend payment dates,
          during the period between the date a Stock Appreciation Right,
          Deferred Stock or Performance Award is granted, and the date such
          Stock Appreciation Right, Deferred Stock or Performance Award is
          exercised, vests or expires, as determined by the Committee. Such
          Dividend Equivalents shall be converted to cash or additional shares
          of Class A Common Stock by such formula and at such time and subject
          to such limitations as may be determined by the Committee.

               (b) Any Holder of an Option who is an Employee or Consultant
          selected by the Committee may be granted Dividend Equivalents based on
          the dividends declared on Class A Common Stock, to be credited as of
          dividend payment dates, during the period between the date an Option
          is granted, and the date such Option is exercised, vests or expires,
          as determined by the Committee. Such Dividend Equivalents shall be
          converted to cash or additional shares of Class A Common Stock by such
          formula and at such time and subject to such limitations as may be
          determined by the Committee.

               (c) Any Holder of an Option who is an Independent Director
          selected by the Board may be granted Dividend Equivalents based on the
          dividends declared on Class A Common Stock, to be credited as of
          dividend payment dates, during the period between the date an Option
          is granted, and the date such Option is exercised, vests or expires,
          as determined by the Board. Such Dividend Equivalents shall be
          converted to cash or additional shares of Class A Common Stock by such
          formula and at such time and subject to such limitations as may be
          determined by the Board.

               (d) Dividend Equivalents granted with respect to Options intended
          to be qualified performance-based compensation for purposes of Section
          162(m) of the Code shall be payable, with respect to pre-exercise
          periods, regardless of whether such Option is subsequently exercised.



                                       19
<PAGE>   20

          8.4. Stock Payments. Any key Employee or Consultant selected by the
Committee may receive Stock Payments in the manner determined from time to time
by the Committee. The number of shares shall be determined by the Committee and
may be based upon the Performance Criteria or other specific performance
criteria determined appropriate by the Committee, determined on the date such
Stock Payment is made or on any date thereafter.

          8.5. Deferred Stock. Any key Employee or Consultant selected by the
Committee may be granted an award of Deferred Stock in the manner determined
from time to time by the Committee. The number of shares of Deferred Stock shall
be determined by the Committee and may be linked to the Performance Criteria or
other specific performance criteria determined to be appropriate by the
Committee, in each case on a specified date or dates or over any period or
periods determined by the Committee. Class A Common Stock underlying a Deferred
Stock award will not be issued until the Deferred Stock award has vested,
pursuant to a vesting schedule or performance criteria set by the Committee.
Unless otherwise provided by the Committee, a Holder of Deferred Stock shall
have no rights as a Company stockholder with respect to such Deferred Stock
until such time as the Award has vested and the Class A Common Stock underlying
the Award has been issued.

          8.6. Term. The term of a Performance Award, Dividend Equivalent, award
of Deferred Stock and/or Stock Payment shall be set by the Committee in its
discretion.

          8.7. Exercise or Purchase Price. The Committee may establish the
exercise or purchase price of a Performance Award, shares of Deferred Stock, or
shares received as a Stock Payment; provided, however, that such price shall not
be less than the par value for a share of Class A Common Stock, unless otherwise
permitted by applicable state law.

          8.8. Exercise Upon Termination of Employment, Termination of
Consultancy or Termination of Directorship. A Performance Award, Dividend
Equivalent, award of Deferred Stock and/or Stock Payment is exercisable or
payable only while the Holder is an Employee, Consultant or Independent
Director, as applicable; provided, however, that the Administrator in its sole
and absolute discretion may provide that the Performance Award, Dividend
Equivalent, award of Deferred Stock and/or Stock Payment may be exercised or
paid subsequent to a Termination of Employment following a "change of control or
ownership" (within the meaning of Section 1.162-27(e)(2)(v) or any successor
regulation thereto) of the Company; provided, further, that except with respect
to Performance Awards granted to Section 162(m) Participants, the Administrator
in its sole and absolute discretion may provide that Performance Awards may be
exercised or paid following a Termination of Employment or a Termination of
Consultancy without cause, or following a Change in Control of the Company, or
because of the Holder's retirement, death or Disability, or otherwise.



          8.9. Form of Payment. Payment of the amount determined under Section
8.2 or 8.3 above shall be in cash, in Class A Common Stock or a combination of
both, as determined by the Committee. To the extent any payment under this
Article VIII is effected in Class A Common Stock, it shall be made subject to
satisfaction of all provisions of Section 6.3.

                                   ARTICLE IX.

                            STOCK APPRECIATION RIGHTS

          9.1. Grant of Stock Appreciation Rights. A Stock Appreciation Right
may be granted to any key Employee or Consultant selected by the Committee. A
Stock Appreciation Right may be granted (a) in connection and simultaneously
with the grant of an Option, (b) with respect to a previously granted Option, or
(c) independent of an Option. A Stock Appreciation Right shall be subject to
such terms and conditions not inconsistent with the Plan as the Committee shall
impose and shall be evidenced by an Award Agreement.

          9.2. Coupled Stock Appreciation Rights.

               (a) A Coupled Stock Appreciation Right ("CSAR") shall be related
          to a particular Option and shall be exercisable only when and to the
          extent the related Option is exercisable.

               (b) A CSAR may be granted to the Holder for no more than the
          number of shares subject to the simultaneously or previously granted
          Option to which it is coupled.

               (c) A CSAR shall entitle the Holder (or other person entitled to
          exercise the Option pursuant to the Plan) to surrender to the Company
          unexercised a portion of the Option to which the CSAR relates (to the
          extent then exercisable pursuant to its terms) and to receive from the
          Company in exchange therefor an amount determined by multiplying the
          difference obtained by subtracting the Option exercise price from the
          Fair Market Value of a share of Class A Common Stock on the date of
          exercise of the CSAR by the number of shares of Class A Common Stock
          with respect to which the CSAR shall have been exercised, subject to
          any limitations the Committee may impose.

          9.3. Independent Stock Appreciation Rights.

               (a) An Independent Stock Appreciation Right ("ISAR") shall be
          unrelated to any Option and shall have a term set by the Committee. An
          ISAR shall be exercisable in such installments as the Committee may
          determine. An ISAR shall cover such number of shares of Class A Common
          Stock as the Committee may determine; provided, however, that unless
          the Committee otherwise provides in the terms of the ISAR or
          otherwise, no ISAR granted to a person subject to Section 16 of the
          Exchange Act shall be exercisable until at least six months have
          elapsed from (but excluding) the date on which the Option was granted.
          The exercise price per share of Class A Common Stock subject to each
          ISAR shall be set by the Committee. An ISAR is exercisable only while
          the Holder is an Employee or Consultant; provided that the Committee
          may determine that the ISAR may be exercised subsequent to Termination
          of Employment or Termination of Consultancy without cause, or
          following a Change in Control of the Company, or because of the
          Holder's retirement, death or Disability, or otherwise.

               (b) An ISAR shall entitle the Holder (or other person entitled to
          exercise the ISAR pursuant to the Plan) to exercise all or a specified
          portion of the ISAR (to the extent then exercisable pursuant to its
          terms) and to receive from the Company an amount determined by
          multiplying the difference obtained by subtracting the exercise price
          per share of the ISAR from the Fair Market Value of a share of Class A
          Common Stock on the date of exercise of the ISAR by the number of
          shares of Class A Common Stock with respect to which the ISAR shall
          have been exercised, subject to any limitations the Committee may
          impose.

          9.4. Payment and Limitations on Exercise.

               (a) Payment of the amounts determined under Section 9.2(c) and
          9.3(b) above shall be in cash, in Class A Common Stock (based on its
          Fair Market Value as of the date the Stock Appreciation Right is
          exercised) or a combination of both, as determined by the Committee.
          To the extent such payment is effected in Class A Common Stock it
          shall be made subject to satisfaction of all provisions of Section 6.3
          above pertaining to Options.

               (b) Holders of Stock Appreciation Rights may be required to
          comply with any timing or other restrictions with respect to the
          settlement or exercise of a Stock Appreciation Right, including a
          window-period limitation, as may be imposed in the discretion of the
          Committee.

                                   ARTICLE X.

                                 ADMINISTRATION

          10.1. Compensation Committee. Prior to the Company's initial
registration of Class A Common Stock under Section 12 of the Exchange Act, the
Compensation Committee shall consist of the entire Board. Following such
registration, The Compensation Committee (or another committee or a subcommittee
of the Board assuming the functions of the Committee under the Plan) shall
consist solely of two or more Independent Directors appointed by and holding
office at the pleasure of the Board, each of whom is both a "non-employee
director" as defined by Rule 16b-3 and an "outside director" for purposes of
Section 162(m) of the Code. Appointment of Committee members shall be effective
upon acceptance of appointment. Committee members may resign at any time by
delivering written notice to the Board. Vacancies in the Committee may be filled
by the Board.

          10.2. Duties and Powers of Committee. It shall be the duty of the
Committee to conduct the general administration of the Plan in accordance with
its provisions. The Committee shall have the power to interpret the Plan and the
Award Agreements, and to adopt such rules for the administration,
interpretation, and application of the Plan as are consistent therewith, to
interpret, amend or revoke any such rules and to amend any Award Agreement
provided that the rights or obligations of the Holder of the Award that is the
subject of any such Award Agreement are not affected adversely. Any such grant
or award under the Plan need not be the same with respect to each Holder. Any
such interpretations and rules with respect to Incentive Stock Options shall be
consistent with the provisions of Section 422 of the Code. In its absolute



                                       22
<PAGE>   23

discretion, the Board may at any time and from time to time exercise any and all
rights and duties of the Committee under the Plan except with respect to matters
which under Rule 16b-3 or Section 162(m) of the Code, or any regulations or
rules issued thereunder, are required to be determined in the sole discretion of
the Committee. Notwithstanding the foregoing, the full Board, acting by a
majority of its members in office, shall conduct the general administration of
the Plan with respect to Options and Dividend Equivalents granted to Independent
Directors.

          10.3. Majority Rule; Unanimous Written Consent. The Committee shall
act by a majority of its members in attendance at a meeting at which a quorum is
present or by a memorandum or other written instrument signed by all members of
the Committee.

          10.4. Compensation; Professional Assistance; Good Faith Actions.
Members of the Committee shall receive such compensation, if any, for their
services as members as may be determined by the Board. All expenses and
liabilities which members of the Committee incur in connection with the
administration of the Plan shall be borne by the Company. The Committee may,
with the approval of the Board, employ attorneys, consultants, accountants,
appraisers, brokers, or other persons. The Committee, the Company and the
Company's officers and Directors shall be entitled to rely upon the advice,
opinions or valuations of any such persons. All actions taken and all
interpretations and determinations made by the Committee or the Board in good
faith shall be final and binding upon all Holders, the Company and all other
interested persons. No members of the Committee or Board shall be personally
liable for any action, determination or interpretation made in good faith with
respect to the Plan or Awards, and all members of the Committee and the Board
shall be fully protected by the Company in respect of any such action,
determination or interpretation.

          10.5. Delegation of Authority to Grant Awards. The Committee may, but
need not, delegate from time to time some or all of its authority to grant
Awards under the Plan to a committee consisting of one or more members of the
Committee or of one or more officers of the Company; provided, however, that the
Committee may not delegate its authority to grant Awards to individuals (i) who
are subject on the date of the grant to the reporting rules under Section 16(a)
of the Exchange Act, (ii) who are Section 162(m) Participants or (iii) who are
officers of the Company who are delegated authority by the Committee hereunder.
Any delegation hereunder shall be subject to the restrictions and limits that
the Committee specifies at the time of such delegation of authority and may be
rescinded at any time by the Committee. At all times, any committee appointed
under this Section 10.5 shall serve in such capacity at the pleasure of the
Committee.

                                   ARTICLE XI.

                            MISCELLANEOUS PROVISIONS

          11.1. Not Transferable. No Award under the Plan may be sold, pledged,
assigned or transferred in any manner other than by will or the laws of descent
and distribution or, subject to the consent of the Administrator, pursuant to a
DRO, unless and until such Award has been exercised, or the shares underlying
such Award have been issued, and all restrictions applicable to such shares have
lapsed. No Award or interest or right therein shall be liable for the 



                                       23
<PAGE>   24

debts, contracts or engagements of the Holder or his successors in interest or
shall be subject to disposition by transfer, alienation, anticipation, pledge,
encumbrance, assignment or any other means whether such disposition be voluntary
or involuntary or by operation of law by judgment, levy, attachment, garnishment
or any other legal or equitable proceedings (including bankruptcy), and any
attempted disposition thereof shall be null and void and of no effect, except to
the extent that such disposition is permitted by the preceding sentence.

          During the lifetime of the Holder, only he may exercise an Option or
other Award (or any portion thereof) granted to him under the Plan, unless it
has been disposed of with the consent of the Administrator pursuant to a DRO.
After the death of the Holder, any exercisable portion of an Option or other
Award may, prior to the time when such portion becomes unexercisable under the
Plan or the applicable Award Agreement, be exercised by his personal
representative or by any person empowered to do so under the deceased Holder's
will or under the then applicable laws of descent and distribution.

          11.2. Amendment, Suspension or Termination of the Plan. Except as
otherwise provided in this Section 11.2, the Plan may be wholly or partially
amended or otherwise modified, suspended or terminated at any time or from time
to time by the Administrator. However, without approval of the Company's
stockholders given within twelve months before or after the action by the
Administrator, no action of the Administrator may, except as provided in Section
11.3, increase the limits imposed in Section 2.1 on the maximum number of shares
which may be issued under the Plan. No amendment, suspension or termination of
the Plan shall, without the consent of the Holder alter or impair any rights or
obligations under any Award theretofore granted or awarded, unless the Award
itself otherwise expressly so provides. No Awards may be granted or awarded
during any period of suspension or after termination of the Plan, and in no
event may any Incentive Stock Option be granted under the Plan after the first
to occur of the following events:

               (a) The expiration of ten (10) years from the date the Plan is
          adopted by the Board; or

               (b) The expiration of ten (10) years from the date the Plan is
          approved by the Company's stockholders under Section 11.4.


          11.3. Changes in Class A Common Stock or Assets of the Company,
Acquisition or Liquidation of the Company and Other Corporate Events.

               (a) Subject to Section 11.3 (d), in the event that the
          Administrator determines that any dividend or other distribution
          (whether in the form of cash, Class A Common Stock, other securities,
          or other property), recapitalization, reclassification, stock split,
          reverse stock split, reorganization, merger, consolidation, split-up,
          spin-off, combination, repurchase, liquidation, dissolution, or sale,
          transfer, exchange or other disposition of all or substantially all of
          the assets of the Company, or exchange of Class A Common Stock or
          other securities of the Company, issuance of warrants or other rights
          to purchase Class A Common Stock or other securities of the Company,
          or other similar 



                                       24
<PAGE>   25

          corporate transaction or event, in the Administrator's sole
          discretion, affects the Class A Common Stock such that an adjustment
          is determined by the Administrator to be appropriate in order to
          prevent dilution or enlargement of the benefits or potential benefits
          intended to be made available under the Plan or with respect to an
          Award, then the Administrator shall, in such manner as it may deem
          equitable, adjust any or all of

                    (i) the number and kind of shares of Class A Common Stock
          (or other securities or property) with respect to which Awards may be
          granted or awarded (including, but not limited to, adjustments of the
          limitations in Section 2.1 on the maximum number and kind of shares
          which may be issued and adjustments of the Award Limit),

                    (ii) the number and kind of shares of Class A Common Stock
          (or other securities or property) subject to outstanding Awards, and

                    (iii) the grant or exercise price with respect to any Award.

               (b) Subject to Section 11.3(d), in the event of any transaction
          or event described in Section 11.3(a) or any unusual or nonrecurring
          transactions or events affecting the Company, any affiliate of the
          Company, or the financial statements of the Company or any affiliate,
          or of changes in applicable laws, regulations, or accounting
          principles, the Administrator, in its sole and absolute discretion,
          and on such terms and conditions as it deems appropriate, either by
          the terms of the Award or by action taken prior to the occurrence of
          such transaction or event and either automatically or upon the
          Holder's request, is hereby authorized to take any one or more of the
          following actions whenever the Administrator determines that such
          action is appropriate in order to prevent dilution or enlargement of
          the benefits or potential benefits intended to be made available under
          the Plan or with respect to any Award under the Plan, to facilitate
          such transactions or events or to give effect to such changes in laws,
          regulations or principles:

                    (i) To provide for either the purchase of any such Award for
          an amount of cash equal to the amount that could have been attained
          upon the exercise of such Award or realization of the Holder's rights
          had such Award been currently exercisable or payable or fully vested
          or the replacement of such Award with other rights or property
          selected by the Administrator in its sole discretion;

                    (ii) To provide that the Award cannot vest, be exercised or
          become payable after such event;

                    (iii) To provide that such Award shall be exercisable as to
          all shares covered thereby, notwithstanding anything to the contrary
          in Section 5.3 or 5.4 or the provisions of such Award;

                    (iv) To provide that such Award be assumed by the successor
          or survivor corporation, or a parent or subsidiary thereof, or 



                                       25
<PAGE>   26

          shall be substituted for by similar options, rights or awards covering
          the stock of the successor or survivor corporation, or a parent or
          subsidiary thereof, with appropriate adjustments as to the number and
          kind of shares and prices; and

                    (v) To make adjustments in the number and type of shares of
          Class A Common Stock (or other securities or property) subject to
          outstanding Awards, and in the number and kind of outstanding
          Restricted Stock or Deferred Stock and/or in the terms and conditions
          of (including the grant or exercise price), and the criteria included
          in, outstanding options, rights and awards and options, rights and
          awards which may be granted in the future.

                    (vi) To provide that, for a specified period of time prior
          to such event, the restrictions imposed under an Award Agreement upon
          some or all shares of Restricted Stock or Deferred Stock may be
          terminated, and, in the case of Restricted Stock, some or all shares
          of such Restricted Stock may cease to be subject to repurchase under
          Section 7.5 or forfeiture under Section 7.4 after such event.

               (c) Subject to Sections 11.3(d), 3.2 and 3.3, the Administrator
          may, in its discretion, include such further provisions and
          limitations in any Award, agreement or certificate, as it may deem
          equitable and in the best interests of the Company.

               (d) With respect to Awards which are granted to Section 162(m)
          Participants and are intended to qualify as performance-based
          compensation under Section 162(m)(4)(C), no adjustment or action
          described in this Section 11.3 or in any other provision of the Plan
          shall be authorized to the extent that such adjustment or action would
          cause such Award to fail to so qualify under Section 162(m)(4)(C), or
          any successor provisions thereto. No adjustment or action described in
          this Section 11.3 or in any other provision of the Plan shall be
          authorized to the extent that such adjustment or action would cause
          the Plan to violate Section 422(b)(1) of the Code. Furthermore, no
          such adjustment or action shall be authorized to the extent such
          adjustment or action would result in short-swing profits liability
          under Section 16 or violate the exemptive conditions of Rule 16b-3
          unless the Administrator determines that the Award is not to comply
          with such exemptive conditions. The number of shares of Class A Common
          Stock subject to any Award shall always be rounded to the next whole
          number.

               (e) Notwithstanding the foregoing, in the event that the Company
          becomes a party to a transaction that is intended to qualify for
          "pooling of interests" accounting treatment and, but for one or more
          of the provisions of this Plan or any Award Agreement would so
          qualify, then this Plan and any Award Agreement shall be interpreted
          so as to preserve such accounting treatment, and to the extent that
          any provision of the Plan or any Award Agreement would disqualify the
          transaction from pooling of interests accounting treatment (including,
          if applicable, an entire Award Agreement), then such provision shall
          be null and void. All determinations to be made in connection with the



                                       26
<PAGE>   27

          preceding sentence shall be made by the independent accounting firm
          whose opinion with respect to "pooling of interests" treatment is
          required as a condition to the Company's consummation of such
          transaction.

               (f) The existence of the Plan, the Award Agreement and the Awards
          granted hereunder shall not affect or restrict in any way the right or
          power of the Company or the shareholders of the Company to make or
          authorize any adjustment, recapitalization, reorganization or other
          change in the Company's capital structure or its business, any merger
          or consolidation of the Company, any issue of stock or of options,
          warrants or rights to purchase stock or of bonds, debentures,
          preferred or prior preference stocks whose rights are superior to or
          affect the Class A Common Stock or the rights thereof or which are
          convertible into or exchangeable for Class A Common Stock, or the
          dissolution or liquidation of the company, or any sale or transfer of
          all or any part of its assets or business, or any other corporate act
          or proceeding, whether of a similar character or otherwise.

          11.4. Approval of Plan by Stockholders. The Plan will be submitted for
the approval of the Company's stockholders (by a majority of the outstanding
common stock entitled to vote thereon with the voting rights set forth in the
Company's Amended and Restated Certificate of Incorporation) within twelve
months after the date of the Board's initial adoption of the Plan. Awards may be
granted or awarded prior to such stockholder approval, provided that such Awards
shall not be exercisable nor shall such Awards vest prior to the time when the
Plan is approved by the stockholders, and provided further that if such approval
has not been obtained at the end of said twelve-month period, all Awards
previously granted or awarded under the Plan shall thereupon be canceled and
become null and void. In addition, if the Board determines that Awards other
than Options or Stock Appreciation Rights which may be granted to Section 162(m)
Participants should continue to be eligible to qualify as performance-based
compensation under Section 162(m)(4)(C) of the Code, the Performance Criteria
must be disclosed to and approved by the Company's stockholders no later than
the first stockholder meeting that occurs in the fifth year following the year
in which the Company's stockholders previously approved the Performance
Criteria.

          11.5. Tax Withholding. The Company shall be entitled to require
payment in cash or deduction from other compensation payable to each Holder of
any sums required by federal, state or local tax law to be withheld with respect
to the issuance, vesting, exercise or payment of any Award. The Administrator
may in its discretion and in satisfaction of the foregoing requirement allow
such Holder to elect to have the Company withhold shares of Class A Common Stock
otherwise issuable under such Award (or allow the return of shares of Class A
Common Stock) having a Fair Market Value equal to the sums required to be
withheld.

          11.6. Loans. The Committee may, in its discretion, extend one or more
loans to key Employees in connection with the exercise or receipt of an Award
granted or awarded under the Plan, or the issuance of Restricted Stock or
Deferred Stock awarded under the Plan. The terms and conditions of any such loan
shall be set by the Committee.



                                       27
<PAGE>   28

          11.7. Forfeiture Provisions. Pursuant to its general authority to
determine the terms and conditions applicable to Awards under the Plan, the
Administrator shall have the right to provide, in the terms of Awards made under
the Plan, or to require a Holder to agree by separate written instrument, that
(a) (i) any proceeds, gains or other economic benefit actually or constructively
received by the Holder upon any receipt or exercise of the Award, or upon the
receipt or resale of any Class A Common Stock underlying the Award, must be paid
to the Company, and (ii) the Award shall terminate and any unexercised portion
of the Award (whether or not vested) shall be forfeited, if (b)(i) a Termination
of Employment, Termination of Consultancy or Termination of Directorship occurs
prior to a specified date, or within a specified time period following receipt
or exercise of the Award, or (ii) the Holder at any time, or during a specified
time period, engages in any activity in competition with the Company, or which
is inimical, contrary or harmful to the interests of the Company, as further
defined by the Administrator.

          11.8. Effect of Plan Upon Options and Compensation Plans.

               (a) The adoption of the Plan shall not affect any other
          compensation or incentive plans in effect for the Company or any
          Subsidiary, other than superseding the Amended and Restated Employee
          Equity Participation Plan of Nextera Enterprises, L.L.C., a Delaware
          limited liability company ("Nextera LLC"). Nothing in the Plan shall
          be construed to limit the right of the Company (i) to establish any
          other forms of incentives or compensation for Employees, Directors or
          Consultants of the Company or any Subsidiary or (ii) to grant or
          assume options or other rights or awards otherwise than under the Plan
          in connection with any proper corporate purpose including but not by
          way of limitation, the grant or assumption of options in connection
          with the acquisition by purchase, lease, merger, consolidation or
          otherwise, of the business, stock or assets of any corporation,
          partnership, limited liability company, firm or association.

               (b) Options granted under this Plan to replace options granted
          to the employees of Nextera LLC, shall have the aggregate option
          exercise price, the vesting schedule and term as set forth in the
          Equity Participation Agreements granted by Nextera LLC to the
          optionees thereunder.

          11.9. Lock-Up in Connection with Initial Public Offering. Each Award
Agreement issued pursuant to this Plan prior to the initial public offering of
the Company's Common Stock shall include provisions substantially similar to 
the following:

               "To induce the underwriters that may participate in an initial
          public offering (the "Initial Public Offering") of the Company's 
          Common Stock to continue their efforts in connection with the Initial
          Public Offering, the undersigned, during the period commencing on the
          date hereof and ending 180 days after the date of the final prospectus
          relating to the Initial Public Offering:

                    (i) agrees not to (x) offer, pledge, sell, contract to sell,
          sell any option or contract to purchase, purchase any option or
          contract to sell, grant any option, right or warrant to purchase, or
          otherwise transfer or dispose of, directly or indirectly, any shares
          of Common Stock or any securities convertible into or

          exercisable or exchangeable for Common Stock (including, without
          limitation, shares of Common Stock or securities convertible into or
          exercisable or exchangeable for Common Stock which may be deemed to be
          beneficially owned by the undersigned in accordance with the rules and
          regulations of the Securities and Exchange Commission) or (y) enter
          into any swap or other arrangement that transfers all or a portion of
          the economic consequences associated with the ownership of any Common
          Stock (regardless of whether any of the transactions described in
          clause (x) or (y) is to be settled by the delivery of Common Stock, or
          such other securities, in cash or otherwise), without the prior
          written consent of the lead managing underwriter of such Initial 
          Public Offering;

                    (ii) agrees not to make any demand for, or exercise any
          right with respect to, the registration of any shares of Common Stock
          or any securities convertible into or exercisable or exchangeable for

          underwriter of such Initial Public Offering; and

                    (iii) authorizes the Company to cause the transfer agent to
          decline to transfer and/or to note stop transfer restrictions on the
          transfer books and records of the Company with respect to any shares
          of Common Stock and any securities convertible into or exercisable or
          exchangeable for Common Stock for which the undersigned is the record
          holder and, in the case of any such shares or securities for which the

          records with respect to such shares or securities.

     Notwithstanding the foregoing, the restrictions set forth in clauses (i),
     (ii) and (iii) above shall not apply to any transfer of Common Stock to a
     "Controlled Affiliate" or pursuant to a "Qualified Transfer" (as each such
     term is defined in the Company's Amended and Restated Certificate of

     agrees in writing to be bound by the provisions of this Section ___.

     The undersigned hereby represents and warrants that the undersigned has
     full power and authority to enter into the agreements set forth in this
     Section, and that, upon request, the undersigned will execute any
     additional documents necessary or desirable in connection with the
     enforcement hereof. All authority herein conferred or agreed to be
     conferred shall survive the death or incapacity of the undersigned and any
     obligations of the undersigned shall be binding upon the heirs, personal
     representatives, successors, and assigns of the undersigned."

          11.10. Compliance with Laws. The Plan, the granting and vesting of
Awards under the Plan and the issuance and delivery of shares of Class A Common
Stock and the payment of money under the Plan or under Awards granted or awarded
hereunder are subject to compliance with all applicable federal and state laws,
rules and regulations (including but not limited to state and federal securities
law and federal margin requirements) and to such approvals by any listing,
regulatory or governmental authority as may, in the opinion of counsel for the
Company, be necessary or advisable in connection therewith. Any securities
delivered under the Plan shall be subject to such restrictions, and the person
acquiring such securities shall, if requested by the Company, provide such
assurances and representations to the Company as the Company may deem necessary
or desirable to assure compliance with all applicable legal requirements. To the
extent permitted by applicable law, the Plan and Awards granted or

          11.11. Titles. Titles are provided herein for convenience only and are

Agreement and each such other agreement, document and instrument have been duly
authorized by all necessary action of the Company and no other action on the
part of the Company or the Holders is required in connection therewith.

          This Agreement and each agreement, document and instrument executed
and delivered by the Company pursuant to this Agreement constitutes, or when

Company enforceable in accordance with their terms. The execution, delivery and
performance by the Company of this Agreement and each such agreement, document
and instrument:

                    (i) does not and will not violate any provision of the
          Articles of Organization or by-laws of the Company;

                    (ii) does not and will not violate any laws of the United
          States, or any state or other jurisdiction applicable to the Company
          or require the Company to obtain any approval, consent or waiver of,
          or make any filing with, any person or entity (governmental or
          otherwise) that has not been obtained or made; and

                    (iii) does not and will not result in a breach of,
          constitute a default under, accelerate any obligation under, or give
          rise to a right of termination of any indenture or loan or credit
          agreement or any other agreement, contract, instrument, mortgage,
          lien, lease, permit, authorization, order, writ, judgment, injunction,
          decree, determination or arbitration award to which the Company is a
          party or by which the property of the Company is bound or affected, or

          security interest or other charge or encumbrance on any of the
          Company's assets or the Company Shares, except as specifically
          identified on Schedule 2.5.

          2.6. Real and Personal Property.

               (a) Real Property. Neither the Company nor any of its
Subsidiaries owns any real property. All of the real property leased by the
Company or any of its Subsidiaries is identified on Schedule 2.6(a) (herein
referred to as the "Leased Real Property").

                    (i) Leases. All leases of Leased Real Property are
          identified on Schedule 2.6(a), and true and complete copies thereof
          have been delivered to Buyer. Each of said leases has been duly
          authorized and executed by the parties and is in full force and effect
          and binding and enforceable against the parties thereto. Neither the
          Company nor any of its Subsidiaries is in default under any of said
          leases, nor has any event occurred which, with notice or the passage
          of time, or both, would give rise to such a default. To the Company's
          knowledge, the other party to each of said leases is not in default
          under any of said leases and there is no 



                                       5
<PAGE>   10

          event which, with notice or the passage of time, or both, would give
          rise to such a default.

                    (ii) Consents. To the knowledge of the Company and the
          Representing Parties, except as set forth in Schedule 2.6(a), no
          consent or approval is required with respect to the transactions
          contemplated by this Agreement from the other parties to any lease of
          Leased Real Property or from any regulatory authority, no filing with
          any regulatory authority is required in connection therewith, and to
          the extent that any such consents, approvals or filings are required,
          the Company or the Holders will obtain or complete them before the
          Closing.

                    (iii) Condition of Leased Real Property. Except as set forth
          in Schedule 2.6(a), to the actual knowledge of the Company there are
          no material defects in the physical condition of any portion of the
          Leased Real Property and all such Leased Real Property is in good
          operating condition and repair, has been well maintained and is free
          from infestation by rodents or insects.

                    (iv) Compliance with the Law. Neither the Company nor any
          Subsidiary has received any notice from any governmental authority of
          any violation of any law, ordinance, regulation, license, permit or
          authorization issued with respect to the Leased Real Property that has
          not been heretofore corrected. Neither the Company nor any Subsidiary
          has received any notice of any real estate tax deficiency or
          assessment or is aware of any proposed deficiency, claim or assessment
          with respect to any of the Leased Real Property, or any pending or
          threatened condemnation thereof.

               (b) Personal Property. A complete description of the machinery
and equipment of the Company and each of its Subsidiaries is contained in
Schedule 2.6(b) hereto. Except as specifically disclosed in said Schedule or in
the Base Balance Sheet (as hereinafter defined), the Company and each of its
Subsidiaries has good and marketable title to all of its personal property. None
of such personal property or assets is subject to any mortgage, pledge, lien,
conditional sale agreement, security title, encumbrance or other charge except
as specifically disclosed in said Schedule or in the Base Balance Sheet. The
personal property register included in Schedule 2.6(b) reflects all significant
personal property of the Company and each of its Subsidiaries. Except as
otherwise specified in Schedule 2.6(b) hereto, all leasehold improvements,
furnishings, machinery and equipment of the Company and each of its Subsidiaries
presently necessary to the conduct of the business of the Company and its
Subsidiaries as such business is currently being conducted are in good repair,
have been well maintained, and substantially comply with all applicable laws,
ordinances and regulations, and such machinery and equipment is in good working
order. None of the Representing Parties has received notice of any such law,
ordinance or regulation which could adversely affect the Company, any of its
Subsidiaries or any of their businesses.

          2.7. Financial Statements.

               (a) The Company has delivered to Buyer the following financial
statements, copies of which are attached hereto as Schedule 2.7: consolidated
balance sheets of the Company and its Subsidiaries for its fiscal years ending

cash flows for the three years then ended, of which the consolidated statements
for fiscal years 1994 and 1995 are certified by Price Waterhouse and the
consolidated statements for fiscal year 1996 are certified by BDO Seidman, LLP,

consolidated balance sheet of the Company and its Subsidiaries for the interim
period ending March 31, 1997 (a copy of which is included in Schedule 2.7) which
is hereinafter referred to as the "Base Balance Sheet." Said financial
statements, and the pro forma balance sheet and income statement prepared by the
Company as of July 23, 1997, have been prepared in accordance with generally
accepted accounting principles applied consistently during the periods covered
thereby, and said financial statements, present fairly in all material respects
the financial condition of the Company and each of its Subsidiaries at the dates
of said statements and the results of its operations for the periods covered
thereby, and all other unaudited financial information provided by the Company
to Buyer since the date of the Base Balance Sheet presents fairly and completely
the information purported to be shown thereon.

               (b) As of the date of the Base Balance Sheet, neither the Company
nor any Subsidiary had any liabilities of any nature, whether accrued, absolute
or contingent (including without limitation, liabilities as guarantor or
otherwise with respect to obligations of others, liabilities for taxes due or
then accrued or to become due, or contingent or potential liabilities relating
to activities of the Company or any Subsidiary or the conduct of their business
prior to the date of the Base Balance Sheet), except liabilities stated or
adequately reserved against on the Base Balance Sheet, or reflected in Schedules
furnished to Buyer hereunder as of the date hereof.

               (c) All projected operating results for fiscal year 1997 which
have previously been supplied by the Company to Buyer have been prepared in good
faith on the basis of assumptions by the Company which the Company believed were
reasonable at the time of the preparation of such projections.

               (d) As of the date hereof and as of the Closing, neither the
Company nor any Subsidiary has had and will have any liabilities of any nature,
whether accrued, absolute or contingent (including without limitation,
liabilities as guarantor or otherwise with respect to obligations of others, or
liabilities for taxes due or then accrued or to become due or contingent or
potential liabilities relating to activities of the Company or any Subsidiary or
the conduct of their business prior to the date hereof or the Closing, as the
case may be, regardless of whether claims in respect thereof had been asserted
as of such date), except liabilities (i) stated or adequately reserved against
on the Base Balance Sheet or the notes thereto, (ii) reflected in Schedules
furnished to Buyer hereunder on the



                                       7

date hereof, or (iii) incurred in the ordinary course of business of the Company
or any Subsidiary consistent with the terms of this Agreement.

          2.8. Taxes.

franchise taxes, capital stock taxes, employment and payroll-related taxes,
withholding taxes, stamp taxes, transfer taxes, windfall profit taxes,

               (b) The Company and each of its Subsidiaries has in accordance
with applicable law filed all federal, state, local and foreign tax returns
required to be filed by it through the date hereof, and all such returns
correctly and accurately set forth the amount of any Taxes relating to the
applicable period. A list of all federal, state, local and foreign income tax
returns filed with respect to the Company and its Subsidiaries for taxable
periods ended on or after May 31, 1992 is set forth in Schedule 2.8 attached
hereto, and said Schedule indicates those returns that have been audited or
currently are the subject of an audit. For each taxable period of the Company
and its Subsidiaries ended on or after May 31, 1992, the Company has delivered
to Buyer correct and complete copies of all federal, state, local and foreign
income tax returns, examination reports and statements of deficiencies assessed
against or agreed to by the Company or any of its Subsidiaries.

               (c) Neither the Internal Revenue Service nor any other
governmental authority is now asserting or, to the knowledge of any Representing
Party, threatening to assert against the Company or any Subsidiary any
deficiency or claim for additional Taxes. No claim has ever been made by an
authority in a jurisdiction where the Company or any Subsidiary does not file
reports and returns that the Company or such Subsidiary is or may be subject to
taxation by that jurisdiction. There are no security interests on any of the
assets of the Company or any Subsidiary that arose in connection with any
failure (or alleged failure) to pay any Taxes. Neither the Company nor any
Subsidiary has ever entered into a closing agreement pursuant to Section 7121 of
the Internal Revenue Code of 1986, as amended (the "Code").

               (d) Except as set forth in Schedule 2.8 attached hereto, there
has not been any audit of any tax return filed by the Company or any Subsidiary,
no such audit is in progress, and neither the Company nor any Subsidiary has
been notified by any tax authority that any such audit is contemplated or
pending. Except as set forth in Schedule 2.8, no extension of time with respect
to any date on which a tax return was or is to be filed by the Company or any
Subsidiary is in force, and no waiver or agreement by the 



                                       8
<PAGE>   13

Company or any Subsidiary is in force for the extension of time for the
assessment or payment of any Taxes.

               (e) Neither the Company nor any Subsidiary has ever been (or has
ever had any liability for unpaid Taxes because it once was) a member of an
"affiliated group" (as defined in Section 1504(a) of the Code). Except as set
forth in Schedule 2.8, neither the Company nor any Subsidiary has ever filed,
and has ever been required to file, a consolidated, combined or unitary tax
return with any other entity. Except as set forth in Schedule 2.8, neither the
Company nor any Subsidiary owns and has ever owned a direct or indirect interest
in any trust, partnership, corporation or other entity. Except as set forth in
Schedule 2.8 attached hereto, neither the Company nor any Subsidiary is a party
to any tax sharing agreement.

               (f) The Company has never made any payments and is not obligated
to make any payments that would be deemed to an excess parachute payment under
section 280G of the Code.

               (g) For purposes of this Agreement, all references to Sections of
the Code shall include any predecessor provisions to such Sections and any
similar provisions of federal, state, local or foreign law.

          2.9. Accounts Receivable. All of the accounts receivable of the
Company or any Subsidiary shown or reflected on the Base Balance Sheet or
existing at the date hereof (less the reserve for bad debts set forth on the
Base Balance Sheet) are or will be at the Closing valid and enforceable claims,
fully collectible and subject to no set off or counterclaim. Neither the Company
nor any Subsidiary has any accounts or loans receivable from any person, firm or
corporation which is affiliated with the Company or any Subsidiary or from any
director, officer or employee of the Company or any Subsidiary, except as
disclosed on Schedule 2.9 hereto, and all accounts and loans receivable from any
such person, firm or corporation shall be paid in cash prior to the Closing,
except as disclosed on Schedule 2.9.

          2.10. Intentionally Omitted.

authority to grant the rights purported to be conferred thereby. True and
complete copies of all such licenses or other agreements, and any amendments
thereto, have been provided to Buyer.

valuable non-public information of Company and its Subsidiaries, to execute
agreements under which such employees are required to convey to the Company or a
Subsidiary ownership of all inventions and developments conceived or created by

all such information of Company and its Subsidiaries. Neither the Company nor
any of its Subsidiaries has made any such information available to any person
other than employees of Company and its Subsidiaries except pursuant to written
agreements requiring the recipients to maintain the confidentiality of such
information and appropriately restricting the use thereof. The Company has no
knowledge of any infringement by others of any Intellectual Property rights of
the Company or any Subsidiary.

               (f) The present and contemplated business, activities and
products of the Company and its Subsidiaries do not infringe any Intellectual
Property of any other person. No proceeding charging the Company or any of its
Subsidiaries with infringement of any adversely held Intellectual Property has
been filed or is threatened to be filed. To the Company's knowledge, there
exists no unexpired patent or patent application which 



                                       12
<PAGE>   17

includes claims that would be infringed by or otherwise adversely affect the
products, activities or business of the Company or any Subsidiary. Neither the
Company nor any of its Subsidiaries is making unauthorized use of any
confidential information or trade secrets of any person, including without
limitation, any former employer of any past or present employee of Company or

of their employees have any agreements or arrangements with any persons other
than the Company or its Subsidiaries related to confidential information or
trade secrets of such persons or restricting any such employee's ability to

               (b) Each Employee Program which has ever been maintained by the
Company or any of its Subsidiaries and which has at any time been intended to
qualify under Section 401 (a) or 501(c)(9) of the Code has received a favorable
determination or approval letter from the Internal Revenue Service ("IRS")
regarding its qualification under such section and has, in fact, been qualified
under the applicable section of the Code from the effective date of such
Employee Program through and including the Closing (or, if earlier, the date
that all of such Employee Program's assets were distributed). No event or
omission has occurred which would cause any such Employee Program to lose its
qualification under the applicable Code section.

               (c) The Company does not know and has no reason to know, of any
failure of any party to comply with any laws applicable to the Employee Programs
that have been maintained by the Company or any of its Subsidiaries. With
respect to any Employee Program ever maintained by the Company or any of its
Subsidiaries, there has occurred no "prohibited transaction," as defined in
Section 406 of the Employee Retirement Income Security Act of 1974, as amended
("ERISA") or Section 4975 of the Code, or breach of any duty under ERISA or
other applicable law (including, without limitation, any health care
continuation requirements or any other tax law requirements, or conditions to
favorable tax treatment, applicable to such plan), which could result, directly
or indirectly, in any taxes, penalties or other liability to the Company, any
Subsidiary, or Buyer. No litigation, arbitration, or governmental administrative
proceeding (or investigation) or other proceeding (other than those relating to
routine claims for benefits) is pending or threatened with respect to any such
Employee Program.

               (d) Neither the Company, any Subsidiary or any Affiliate (as
defined below) has ever maintained any Employee Program which has been subject
to title IV of ERISA (including, but not limited to, any Multiemployer Plan (as
defined below)) or (ii) has ever provided health care or any other non-pension
benefits to any employees after 



                                       16
<PAGE>   21

their employment is terminated (other than as required by part 6 of subtitle B
of title I of ERISA) or has ever promised to provide such post-termination
benefits.

               (e) With respect to each Employee Program maintained by the
Company or any Subsidiary within the three years preceding the Closing, complete
and correct copies of the following documents (if applicable to such Employee
Program) have previously been delivered to Buyer: (i) all documents embodying or
governing such Employee Program, and any funding medium for the Employee Program
(including, without limitation, trust agreements) as they may have been amended;
(ii) the most recent IRS determination or approval letter with respect to such
Employee Program under Code Sections 401 or 501(c)(9), and any applications for
determination or approval subsequently filed with the IRS; (iii) the three most
recently filed IRS Forms 5500, with all applicable schedules and accountants'
opinions attached thereto; (iv) the summary plan description for such Employee
Program (or other descriptions of such Employee Program provided to employees)
and all modifications thereto; (v) any insurance policy (including any fiduciary
liability insurance policy) related to such Employee Program; (vi) any documents
evidencing any loan to an Employee Program that is a leveraged employee stock
ownership plan; and (vii) all other materials reasonably necessary for Buyer to
perform any of its responsibilities with respect to any Employee Program
subsequent to the Closing (including, without limitation, health care
continuation requirements).

               (f) Each Employee Plan listed on Schedule 2.25 may be amended,
terminated, modified or otherwise revised prospectively by the Company including
the elimination of any and all future benefit accruals under any Employee Plan.

               (g) For purposes of this section:

                    (i) "Employee Program" means (A) all employee benefit plans
          within the meaning of ERISA Section 3(3), including, but not limited
          to, multiple employer welfare arrangements (within the meaning of
          ERISA Section 3(4)), plans to which more than one unaffiliated
          employer contributes and employee benefit plans (such as foreign or
          excess benefit plans) which are not subject to ERISA; and (B) all
          stock option plans, bonus or incentive award plans, severance pay
          policies or agreements, deferred compensation agreements, supplemental
          income arrangements, vacation plans, and all other employee benefit
          plans, agreements, and arrangements not described in (A) above. In the
          case of an Employee Program funded through an organization described
          in Code Section 501(c)(9), each reference to such Employee Program
          shall include a reference to such organization.

                    (ii) An entity "maintains" an Employee Program if such
          entity sponsors, contributes to, or provides (or has promised to
          provide) benefits under such Employee Program, or has any obligation
          (by agreement or under applicable law) to contribute to or provide
          benefits under such Employee Program, or if such 



                                       17
<PAGE>   22

          Employee Program provides benefits to or otherwise covers employees of
          such entity, or their spouses, dependents, or beneficiaries.

                    (iii) An entity is an "Affiliate" of the Company or a
          Subsidiary if it would have ever been considered a single employer
          with the Company or any of its Subsidiaries under ERISA Section
          4001(b) or part of the same "controlled group" as the Company or any
          of its Subsidiaries for purposes of ERISA Section 302(d)(8)(C).

                    (iv) "Multiemployer Plan" means a (pension or non-pension)
          employee benefit plan to which more than one employer contributes and
          which is maintained pursuant to one or more collective bargaining
          agreements.

question concerning representation exists respecting any employees of the
Company or any of its Subsidiaries. There are no grievances, complaints or
charges that have been filed against the Company or any of its Subsidiaries

bargaining agreement) that might have an adverse effect on the Company or any of
its Subsidiaries or the conduct of their respective businesses, and there is no
arbitration or similar proceeding pending and no claim therefor has been
asserted. No collective bargaining agreement is in effect or is currently being

that any of its employment policies or practices is currently being audited or
investigated by any federal, state or local government agency. The Company and

indications of interest from third parties regarding possible acquisitions,
joint ventures or additional types of financing, including a possible public

                                       36
<PAGE>   41

Parties for claims for indemnification shall be limited as follows:

                    (i) For claims for indemnification made prior to the date
          one year following the Closing pursuant to Tax Claims and General
          Claims, the aggregate amount to be payable to all Buyer Indemnified
          Parties shall in no event exceed the Escrow Amount plus the sum of ONE
          MILLION SEVEN HUNDRED AND FIFTY THOUSAND DOLLARS ($1,750,000);
          provided, however, (in addition to the foregoing overall aggregate
          limit for all such Tax Claims and General Claims) that (A) the
          aggregate amount to be payable to all Buyer Indemnified Parties for
          such claims for indemnification pursuant to General Claims shall not
          exceed the Escrow Amount (and a Buyer Indemnified Party's sole and
          exclusive remedy and recourse for all General Claims shall be limited
          to the Escrow Amount pursuant to the terms of the Escrow Agreement)
          and (B) the aggregate amount to be payable to all Buyer Indemnified
          Parties for such claims for indemnification pursuant to Tax Claims

          date one year following the Closing pursuant to Tax Claims, the
          aggregate amount to be payable to all Buyer Indemnified Parties shall

          claims for indemnification pursuant to Tax Claims made prior to the
          date one year following the Closing or (b) the sum of ONE MILLION
          SEVEN HUNDRED AND FIFTY THOUSAND DOLLARS ($1,750,000) plus any amounts
          distributed or distributable out of the Escrow Amount by the Escrow
          Agent to the Holders under the Escrow Agreement as of the date which
          is one year following the Closing minus the aggregate amount payable
          or paid in respect of claims for indemnification pursuant to Tax
          Claims made prior to the date one year following the Closing (other
          than any such amount paid out of the Escrow Amount); and



                                       37
<PAGE>   42

                    (iii) The aggregate amount payable to all Buyer Indemnified
          Parties for claims for indemnification pursuant to Non-Attributable
          Fraud Claims (as such term is defined below) by (i) SAIC or (ii) a
          Holder who receives aggregate proceeds (including any amounts
          deposited with the Escrow Agent pursuant to the terms of the Escrow
          Agreement) for such Holder's Company Shares and Options of less than
          TWO HUNDRED THOUSAND DOLLARS ($200,000), shall not exceed the
          aggregate proceeds received by such Holder whether or not such Holder
          obtains any reimbursement or recovery for such amount from any other
          party or entity. As used in this Section 10.2(d)(iii), a
          "Non-Attributable Fraud Claim" as it relates to a Holder is any Fraud
          Claim related to which a court of competent jurisdiction (or an
          arbitrator if such Fraud Claim is made against the Escrow Amount and
          is disputed pursuant to Section 4 of the Escrow Agreement) determines
          that such Holder did not personally commit fraud or intentional
          misrepresentation or cause or have knowledge of a deliberate or
          willful breach of any representation, warranty or covenant under this
          Agreement or in any certificate, schedule or exhibit delivered
          pursuant hereto.

               (e) Claims for indemnification with respect to covenants to be
performed post-Closing, Fraud Claims (other than as provided in Section
10.2(d)(iii)), Ownership and Authority Claims or Excluded Liability Claims
(other than as provided in Section 10.2(c)) made under this Agreement by any
Buyer Indemnified Party shall not be subject to the limitations set forth in
this Section 10.2.

               (f) The amount to be payable by a Holder to all Buyer Indemnified
Parties for claims for indemnification for General Claims shall in no event
exceed such Holder's pro rata share of the Escrow Amount and the amount to be
payable by a Holder (whether payable from the Escrow Account or otherwise) to
all Buyer Indemnified Parties for claims for indemnification pursuant to Tax
Claims shall in no event exceed such Holder's pro rata share of the total amount
to be paid to all Buyer Indemnified Parties for claims for indemnification

               (g) Anything contained in this Agreement to the contrary
notwithstanding, the aggregate amount payable by SAIC to all Buyer Indemnified
Parties for any claims for indemnification pursuant to Section 10.1, other than
claims for indemnification pursuant to an Individual Claim or Fraud Claims
(unless it is a Non-Attributable Fraud Claim, in which case Section 10.2 (d)
(iii) shall govern) shall not exceed the aggregate proceeds received by SAIC,
including any amounts received from the Escrow Agent pursuant to the terms of
the Escrow Agreement. After SAIC has paid the aggregate proceeds received by
SAIC to the Buyer Indemnified Parties, including any amounts received from the
Escrow Agent pursuant to the terms of the Escrow Agreement, whether or not SAIC
obtains any reimbursement or recovery for such amounts from any other party or
entity, SAIC shall have no liability or obligation to provide any
indemnification to any Buyer Indemnified party (other than to provide
indemnification for claims pursuant to an Individual Claim or Fraud Claims
(unless it is a Non-Attributable Fraud Claim, in which case Section 10.2 (d)
(iii) shall govern)) and no Buyer Indemnified Parties shall have any right to
indemnification under Section 10.1 against SAIC, except for claims pursuant to
an Individual Claim or Fraud Claims (unless it is a Non-Attributable Fraud
Claim, in which case Section 10.2 (d) (iii) shall govern).

          10.3. Indemnification by Buyer. Buyer agrees to indemnify and hold the
Holders (individually a "Holder Indemnified Party" and collectively the "Holder
Indemnified Parties") harmless from and against any damages, liabilities, losses
and expenses (including, without limitation, reasonable fees of counsel) of any
kind or nature whatsoever (whether or not arising out of third-party claims and
including all amounts paid in investigation, defense or settlement of the
foregoing) which may be sustained or suffered by any of them arising out of or
based upon any breach of any representation, warranty or covenant made by Buyer
in this Agreement or in any certificate delivered by Buyer hereunder, or by
reason of any claim, action or proceeding asserted or instituted growing out of
any matter or thing constituting such a breach.

          10.4. Limitation on Indemnification by Buyer. Notwithstanding the
foregoing, no indemnification shall be payable to the Holders with respect to
claims asserted pursuant to Section 10.3 above after the date which is six (6)
months after the Closing and the aggregate amount to be payable to Holders
pursuant to Section 10.3 shall not exceed ONE MILLION SEVEN HUNDRED AND FIFTY
THOUSAND DOLLARS ($1,750,000); provided, however, that the limitations set forth
herein shall not apply to a claim for indemnification based upon a breach of
Section 5.2 or 5.3 or covenants to be performed post-Closing.

          10.5. Notice; Defense of Claims. An indemnified party shall make
claims for indemnification hereunder by giving written notice thereof to the
indemnifying party within the period in which indemnification claims can be made
hereunder. If indemnification is sought for a claim or liability asserted by a
third party, the indemnified party shall also give written notice thereof to the
indemnifying party promptly after it receives notice of the claim or liability
being asserted, but the failure to do so shall not relieve the indemnifying
party from any liability except to the extent that it is prejudiced by the
failure or delay in giving such notice. Such notice shall summarize the bases
for the claim for indemnification and any claim or liability being asserted by a
third party. Within 20 days after receiving such notice the indemnifying party
shall give written 



                                       39
<PAGE>   44
notice to the indemnified party stating whether it disputes the claim for
indemnification and whether it will defend against any third party claim or
liability at its own cost and expense. If the indemnifying party fails to give
notice that it disputes an indemnification claim within 20 days after receipt of
notice thereof, it shall be deemed to have accepted and agreed to the claim,
which shall become immediately due and payable. The indemnifying party shall be
entitled to direct the defense against a third party claim or liability with
counsel selected by it (subject to the consent of the indemnified party, which
consent shall not be unreasonably withheld) as long as the indemnifying party is
conducting a good faith and diligent defense. The indemnified party shall at all
times have the right to fully participate in the defense of a third party claim
or liability at its own expense directly or through counsel; provided, however,
that if the named parties to the action or proceeding include both the
indemnifying party and the indemnified party and the indemnified party is
advised that representation of both parties by the same counsel would be
inappropriate under applicable standards of professional conduct, the
indemnified party may engage separate counsel at the expense of the indemnifying
party. If no such notice of intent to dispute and defend a third party claim or
liability is given by the indemnifying party, or if such good faith and diligent
defense is not being or ceases to be conducted by the indemnifying party, the
indemnified party shall have the right, at the expense of the indemnifying
party, to undertake the defense of such claim or liability (with counsel
selected by the indemnified party), and to compromise or settle it, exercising
reasonable business judgment. If the third party claim or liability is one that
by its nature cannot be defended solely by the indemnifying party, then the
indemnified party shall make available such information and assistance as the
indemnifying party may reasonably request and shall cooperate with the
indemnifying party in such defense, at the expense of the indemnifying party.

          10.6. Satisfaction of Holder Indemnification Obligations. In order to
satisfy the indemnification obligations of the Holders for General Claims, a
Buyer Indemnified Party shall have the sole right to proceed directly against
the Escrow Amount as further set forth in the Escrow Agreement. In order to
satisfy any other indemnification obligation of the Holders, a Buyer Indemnified
Party shall have the right to (i) proceed directly against the Escrow Amount as
further set forth in the Escrow Agreement; (ii) proceed directly against the
Holders (in the case of Tax Claims, subject to Section 10.2(f)); (iii) if such
obligation is covered by the Indemnification Insurance, make a claim against the
Indemnification Insurance; or (iv) exercise all of such remedies. Anything
herein contained to the contrary notwithstanding, if a Buyer Indemnified Party
shall receive payment for a claim, or a portion thereof, under the
Indemnification Insurance, such Buyer Indemnified Party shall have no right to
receive payment from the Escrow Amount or directly from any Holder for the
portion, if any, of the claim that is satisfied by payment to such Buyer
Indemnified Party under the Indemnification Insurance.

SECTION 11. MISCELLANEOUS.

          11.1. Fees and Expenses.

               (a) Each of the parties will bear its own expenses in connection
with the negotiation and the consummation of the transactions contemplated by
this Agreement; provided, however, that the Company shall pay expenses, not to
exceed 



                                       40
<PAGE>   45

$150,000, incurred by the Holders in connection with the transfer of the Company
Shares to Buyer, but not including taxes or the costs or expenses, if any,
incurred by the Optionholders in connection with the cancellation of the
Options.

          11.2. Governing Law. This Agreement shall be construed under and
governed by the internal laws of the Commonwealth of Massachusetts without
regard to its conflict of laws provisions.

          11.3. Notices. Any notice, request, demand or other communication
required or permitted hereunder shall be in writing and shall be deemed to have

receipt is acknowledged or the expiration of three days after deposit in United

Any notice given hereunder may be given on behalf of any party by his counsel or
other authorized representatives.

          11.4. Affirmation of Agreements. Buyer hereby agrees to be bound by
the terms of the Company's agreement with Massachusetts Mutual Life Insurance
Company executed in the form of Exhibit H, as required by Section 14 of such
agreement. Buyer also hereby acknowledges the Non-Competition and Endorsement
Agreement dated as of August 25, 1995 by and between the Company and George
Bennett and Buyer agrees to cause the Company to perform the obligations of the
Company under such agreement.

          11.5. Entire Agreement. This Agreement, including the Schedules and
Exhibits referred to herein and the other writings specifically identified
herein or contemplated hereby, is complete, reflects the entire agreement of the
parties with respect to its subject matter, and supersedes all previous written
or oral negotiations, commitments and writings. No promises, representations,
understandings, warranties and agreements have been made by any of the parties
hereto except as referred to herein or in such Schedules and Exhibits or in such
other writings; and all inducements to the making of this Agreement relied upon
by either party hereto have been expressed herein or in such Schedules or
Exhibits or in such other writings.

          11.6. Assignability; Binding Effect. This Agreement shall only be
assignable by Buyer to a corporation or partnership controlling, controlled by
or under common control with Buyer upon written notice to the Company and the
Holders. This Agreement may not be assigned by any Holders or the Company
without the prior written consent of Buyer. This Agreement shall be binding upon
and enforceable by, and shall inure to the benefit of, the parties hereto and
their respective successors and permitted assigns.

          11.7. Captions and Gender. The captions in this Agreement are for
convenience only and shall not affect the construction or interpretation of any
term or provision hereof. The 



                                       42
<PAGE>   47

use in this Agreement of the masculine pronoun in reference to a party hereto
shall be deemed to include the feminine or neuter, as the context may require.

          11.8. Execution in Counterparts. For the convenience of the parties
and to facilitate execution, this Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which shall
constitute one and the same document.

          11.9. Amendments. This Agreement may not be amended or modified, nor
may compliance with any condition or covenant set forth herein be waived, except
by a writing duly and validly executed by each party hereto, or in the case of a
waiver, the party waiving compliance.

          11.10. Publicity and Disclosures. No press releases or public
disclosure, either written or oral, of the transactions contemplated by this
Agreement, shall be made by a party to this Agreement without the prior
knowledge and written consent of Buyer and the Company.

          11.11. Consent to Jurisdiction. Each of the parties hereby consents to
personal jurisdiction, service of process and venue in the federal or state
courts of Massachusetts for any claim, suit or proceeding arising under this
Agreement, or in the case of a third party claim subject to indemnification
hereunder, in the court where such claim is brought.

          11.12. Specific Performance. The parties agree that it would be
difficult to measure damages which might result from a breach of this Agreement
by the Company or the Holders and that money damages would be an inadequate
remedy for such a breach. Accordingly, if there is a breach or proposed breach
of any provision of this Agreement by the Company or the Holders, and Buyer does
not elect to terminate under Section 8, Buyer shall be entitled, in addition to
any other remedies which it may have, to an injunction or other appropriate
equitable relief to restrain such breach without having to show or prove actual
damage to Buyer.

          11.13. Conflict with Option Cancellation Agreement. The Holders agree
that, in the event the amount payable to a Holder pursuant to the documents
canceling the Options held by such Holder is less than the amount payable to
such Holder as set forth on Exhibit B attached hereto, the amount payable to
such Holder for the cancellation of such Holder's Options shall be the amount
set forth on Exhibit B attached hereto.

                                                                EXHIBIT NO. 10.3

                                ESCROW AGREEMENT

          AGREEMENT made as of July 30, 1997 by and among Nextera Enterprises,
L.L.C., a Delaware limited liability company ("Buyer"), Symmetrix, Inc., a
Massachusetts corporation (the "Company"), the holders of the Company's capital
stock set forth on Exhibit A attached hereto (herein collectively referred to as
the "Stockholders" and individually as a "Stockholder") and certain holders of
options to purchase shares of the Company's capital stock set forth on Exhibit B
attached hereto (herein collectively referred to as the "Optionholders " and
individually as an "Optionholder;" the Stockholders and the Optionholders are
collectively referred to as the "Holders" and individually as a "Holder") and
State Street Bank and Trust Company, as escrow agent (the "Escrow Agent").

          WHEREAS, pursuant to a Stock Purchase Agreement (the "Stock Purchase
Agreement") dated as of July 30, 1997 by and among Buyer, the Company and the
Holders, Buyer is acquiring the all outstanding shares of the Company's capital
stock from the Stockholders and the Company is canceling the options to purchase
capital stock of the Company held by the Optionholders; and

          WHEREAS, the Holders have agreed to indemnify Buyer against breaches
of the representations, warranties and covenants made by the Company and certain
of the Holders in the Stock Purchase Agreement and against certain other matters
as specified in Section 10 of the Stock Purchase Agreement; and

          WHEREAS, to secure payment of certain of the Holders' indemnification
obligations, ONE MILLION SEVEN HUNDRED AND FIFTY THOUSAND DOLLARS ($1,750,000)
(such amount, the "Escrow Amount") is being deposited, pursuant to Section 1.3
of the Stock Purchase Agreement, in escrow to be held as hereinafter provided.

          NOW, THEREFORE, in consideration of the foregoing and the mutual
promises of the parties herein contained, and other good and valuable
consideration, receipt and sufficiency of which is hereby acknowledged, the
parties hereto agree as follows:

          1. Establishment of Escrow: Investment. Buyer has herewith deposited
the Escrow Amount with the Escrow Agent on the date of the Closing. The
consideration deposited hereunder, including any additions to or earnings on the
same, shall be referred to as the "Escrow Fund." The Escrow Fund shall be held
in escrow in an account designated as the Symmetrix, Inc. Escrow Account or an
account having such other similar designation, subject to the terms and
conditions set forth herein. Patrick Flynn shall serve as the exclusive
representative of the Holders with respect to the Escrow Fund and this Agreement
(the "Escrow Representative"). If, for any reason, the Escrow Representative
shall be either unable or unwilling to serve, a successor Escrow Representative
shall be appointed by written consent of all Holders and all references to the
Escrow Representative shall be deemed to include such successor. Unless
otherwise directed in writing by the Escrow Representative and Buyer, the Escrow
Agent shall invest the cash held in the Escrow Fund in any State Street Insured
Money Market Account, U.S. Government obligations, bank certificates of deposit
(up to the maximum insured amount of any such deposit) or repurchase agreements
secured by U.S. Government obligations, (individually, an "Investment" 



<PAGE>   2

and collectively, the "Investments"), and the Escrow Agent shall not be
responsible for any loss incurred upon any such investment made in good faith.
Unless otherwise directed in writing by the Escrow Representative and Buyer, the
Escrow Agent shall not invest all or any portion of the Escrow Fund in any
Investment if the maturity date of such Investment is later than the Termination
Date (as defined below).

          2. Amounts Earned on Escrow Fund: Tax Matters. All amounts earned,
paid or distributed with respect to the Escrow Fund (whether interest, dividends
or otherwise) shall become a part of the Escrow Fund, shall be held hereunder
upon the same terms as the original Escrow Fund and shall be distributed
together with the underlying portion of the original Escrow Fund pursuant to the
terms of this Agreement. The parties agree that to the extent permitted by
applicable law, including Section 46813(g) of the Internal Revenue Code of 1986,
as amended, the Buyer will include all amounts earned on the Escrow Fund in its
gross income for federal, state and local income tax (collectively, "income
tax") purposes and pay any income tax resulting therefrom.

          3. Claims Against Escrow Fund. At any time or times prior to the
expiration of this Agreement, Buyer may make claims against the Escrow Fund for
indemnification pursuant to and in accordance with Section 10 of the Stock
Purchase Agreement. Buyer shall notify the Escrow Representative and the Escrow
Agent in writing prior to the expiration of this Agreement of each such claim,
including a summary of the amount of and bases for such claim. If the Escrow
Representative shall dispute such claim, the Escrow Representative shall give
written notice thereof to Buyer and to the Escrow Agent within thirty (30) days
after receipt of notice of Buyer's claim, in which case the Escrow Agent shall
continue to hold the Escrow Fund in accordance with the terms of this Agreement;
otherwise, such claim shall be deemed to have been acknowledged to be payable
out of the Escrow Fund in the full amount thereof and the Escrow Agent shall use
its best efforts to pay such claim in immediately available funds to Buyer
within three (3) business days after expiration of said thirty day period or as
soon thereafter as possible. If the amount of the claim exceeds the value of the
Escrow Fund, the Escrow Agent shall have no liability or responsibility for any
deficiency.

          4. Disputed Claims.

               (a) If the Escrow Representative shall dispute an indemnification
claim of Buyer as above provided, the Escrow Agent shall set aside a portion of
the Escrow Fund sufficient to pay said claim in full (the "Set Aside Amount").
If Buyer notifies the Escrow Agent in writing that it has made out-of-pocket
expenditures in connection with any such disputed claim, and provides paid
receipts for such expenditures, in addition to expenditures included in the Set
Aside Amount, an amount equal to such additional expenditures shall be added to
the Set Aside Amount.

               (b) If the disputed indemnification claim has not been resolved
or compromised within sixty (60) days after the Escrow Representative sends
notice of dispute of the same, or in the event of a third-party claim or suit,
within fifteen (15) days after its resolution or compromise, said
indemnification claim shall be referred to the American Arbitration Association,
to be settled 



                                       2
<PAGE>   3

by binding arbitration in Boston, Massachusetts, in accordance with the
commercial arbitration rules of the Association. The fees and expenses of the
arbitrator shall, as between the Holders and Buyer, be borne by them in such
proportions as shall be determined by the arbitrator, or if there is no such
determination, then such fees and expenses shall be borne equally by the Holders
and Buyer. In no event shall the Escrow Agent be responsible for any fee or
expense of any party to any arbitration proceeding. The determination of the
arbitrator as to the amount, if any, of the indemnification claim which is
properly allowable shall be conclusive and binding upon the parties hereto and
judgment may be entered thereon in any court having jurisdiction thereof,
including, without limitation, any Superior Court in the Commonwealth of
Massachusetts. The Escrow Agent shall use its best efforts to make payment of
such claim, as and to the extent allowed, to Buyer out of the Set Aside Amount
(or if insufficient, out of the Escrow Fund) within three (3) business days
following said determination or as soon thereafter as possible.

               (c) Notwithstanding Section 4(b), if a disputed indemnification
claim has not been resolved or compromised as of the Termination Date (as
hereinafter defined), and such claim does not involve a third-party claim or
suit, Buyer and the Escrow Representative shall continue to negotiate in good
faith a settlement of such claims for a period of ten (10) days. If, after the
expiration of such ten-day period, such indemnification claim still has not been
resolved or compromised, such claim shall be settled in accordance with the
arbitration provisions set forth in Section 4(b).

               (d) It is understood and agreed that should any dispute arise
under this Section 4, the Escrow Agent, upon receipt of written notice of such
dispute or claim by the Escrow Representative, is authorized and directed to
retain in its possession without liability to anyone, the Set Aside Amount
relating to such dispute plus any expenditures of Buyer made pursuant to Section
4(a) until such dispute shall have been settled pursuant to this Section 4. The
Escrow Agent may, but shall be under no duty whatsoever to, institute or defend
any legal proceedings which relate to the Escrow Fund.

          5. Termination. This Agreement shall terminate on the date that the
Escrow Fund is reduced to zero as the result of payments by the Escrow Agent to
Buyer in accordance with the provisions of Section 3 or Section 4. If, however,
the Escrow Fund has not been reduced to zero as of the date that is one (1) year
following the date of this Agreement (the "Termination Date") and there are no
outstanding indemnification claims on the Termination Date, this Agreement shall
terminate and the Escrow Agent shall distribute the amount remaining in the
Escrow Fund to the Holders in accordance with their pro rata interest in the
Escrow Fund as set forth in Exhibit C attached hereto; otherwise this Agreement
shall continue in effect until all indemnification claims Buyer has made
pursuant to Section 3 hereof on or prior to the Termination Date shall have been
disposed of. As of the Termination Date, an amount of the Escrow Fund adequate
to cover all disputed and undisputed claims made by Buyer pursuant to Section 3
hereof, plus an additional twenty percent (20%) of any such amount to cover
expenses of Buyer associated with such claims, will be held by the Escrow Agent,
and the Escrow Agent shall distribute on the Termination Date the balance, if
any, of the Escrow Fund to the Holders in accordance with their pro rata
interest in the Escrow Fund as set forth in Exhibit C attached hereto. At such
time as all remaining indemnification claims hereunder have been resolved and
the Escrow Agent has 



                                       3
<PAGE>   4

received a written notice executed by Buyer and the Escrow Representative, or
notification of a determination of an arbitrator pursuant to Section 4(b), to
that effect and any amounts to be distributed to Buyer in connection therewith
have been so distributed, the Escrow Agent shall distribute the remaining Escrow
Fund, if any, to the Holders in accordance with their pro rata interest in the
Escrow Fund.

          6. The Escrow Agent. Notwithstanding anything herein to the contrary,
the Escrow Agent shall promptly dispose of all or any part of the Escrow Fund as
directed by a writing signed by the Escrow Representative and Buyer. The
reasonable fees and expenses of the Escrow Agent, including legal fees incurred
in connection with the preparation of this Agreement and including the fees and
disbursements of its counsel, if any, in connection with its performance of this
Agreement shall be paid from the income on the Escrow Fund and, if and to the
extent not so paid, shall be borne equally by the Holders and Buyer. The Escrow
Agent shall be entitled to reimbursement on demand for all expenses incurred in
connection with the administration of this Agreement or the escrow created
hereby which are in excess of its compensation for normal services hereunder,
including without limitation, payment of any legal fees and expenses incurred by
the Escrow Agent in connection with resolution of any dispute hereunder. The
Escrow Agent, its directors, officers and employees shall not be liable for any
act or omission to act under this Escrow Agreement except for its own gross
negligence or willful misconduct. The Escrow Agent shall not be liable for, and
Buyer, the Company and the Holders shall jointly and severally indemnify the
Escrow Agent against, any losses or claims arising out of or any action taken or
omitted in good faith hereunder and upon the advice of counsel, including
in-house counsel. The Escrow Agent may decline to act and shall not be liable
for failure to act if in doubt as to its duties under this Agreement. The Escrow
Agent may act upon any instrument or signature believed by it to be genuine and
shall have no responsibility for determining the accuracy thereof, and may
assume that any person purporting to give any notice or instruction hereunder,
reasonably believed by it to be authorized, has been duly authorized to do so.
The Escrow Agent's duties shall be determined only with reference to this Escrow
Agreement and applicable laws, and the Escrow Agent is not charged with
knowledge of or any duties or responsibilities in connection with any other
document or agreement, including the Stock Purchase Agreement. The Escrow Agent
shall not be obligated to take any legal or other action hereunder which might
in its judgment involve any expense or liability unless it shall have been
furnished with acceptable indemnification. In no event shall the Escrow Agent be
liable for indirect, punitive, special or consequential damages.

          Buyer, the Company and the Holders jointly and severally, agree to
assume any and all obligations imposed now or hereafter by any applicable tax
law with respect to the payment of Escrow Funds under this Agreement, and to
indemnify and hold the Escrow Agent harmless from and against any taxes,
additions for late payment, interest, penalties and other expenses, that may be
assessed against the Escrow Agent in any such payment or other activities under
this Agreement. Buyer, the Company and the Holders undertake to instruct the
Escrow Agent in writing with respect to the Escrow Agent's responsibility for
withholding and other taxes, assessments or other governmental charges,
certifications and governmental reporting in connection with its acting as
Escrow Agent under this Agreement. Buyer, the Company and the Holders, jointly
and severally, agree to indemnify and hold the Escrow Agent harmless from any



                                       4
<PAGE>   5

liability on account of taxes, assessments or other governmental charges,
including without limitation the withholding or deduction or the failure to
withhold or deduct the same, and any liability for failure to obtain proper
certifications or to properly report to governmental authorities, to which the
Escrow Agent may be or become subject in connection with or which arises out of
this Agreement, including costs and expenses (including reasonable legal fees
and expenses), interest and penalties.

          The Escrow Agent shall have the right at any time to resign hereunder
by giving written notice of its resignation to the parties hereto, at the
addresses set forth herein or at such other address as the parties shall
provide, at least thirty (30) business days prior to the date specified for such
resignation to take effect. If the parties hereto do not designate a successor
escrow agent within said thirty (30) business days, the Escrow Agent may apply
to a court of competent jurisdiction for appointment of a successor escrow
agent. The provisions of paragraph 6 shall survive termination of this
Agreement. Upon the effective date of such resignation, all cash and other
payments and all other property then held by the Escrow Agent hereunder shall be
delivered by it to such successor escrow agent or as otherwise shall be
designated in writing by the parties hereto.

          In the event that the Escrow Agent should at any time be confronted
with inconsistent or conflicting claims or demands by the parties hereto, the
Escrow Agent shall have the right but not the duty to interplead said parties in
any court of competent jurisdiction and request that such court determine such
respective rights of the parties with respect to this Escrow Agreement, and upon
doing so, the Escrow Agent shall be released from any obligations or liability
to either party as a consequence of any such claims or demands.

          The Escrow Agent may execute any of its powers or responsibilities
hereunder and exercise any rights hereunder, either directly or by or through
its agents or attorneys including in-house counsel. Nothing in this Escrow
Agreement shall be deemed to impose upon the Escrow Agent any duty to qualify to
do business or to act as fiduciary or otherwise in any jurisdiction other than
the State of Massachusetts. The Escrow Agent shall not be responsible for and
shall not be under a duty to examine into or pass upon the validity, binding
effect, execution or sufficiency of this Escrow Agreement or of any agreement
amendatory or supplemental hereto.

          7. Miscellaneous. This Agreement shall be construed under and governed
by the laws of the Commonwealth of Massachusetts and shall inure to the benefit
of and be binding upon the successors, assigns, heirs and personal
representatives of the parties hereto.

          8. Counterparts. This Escrow Agreement may be executed in one or more
counterparts, all of which documents shall be considered one and the same
document.

          9. Notices. Any notice or other communication required or permitted
hereunder shall be in writing and shall be deemed to have been given when
received, if personally delivered or sent by facsimile transmission, or three
(3) days after deposited in the U.S. mails for delivery by registered or
certified mail, return receipt requested, postage prepaid, addressed as follows:

agree to provide the Escrow Agent with a certified tax identification number by

to the Escrow Agent prior to the date on which any income earned on the
investment of the Escrow Funds is credited to such Escrow Funds. The parties
hereto understand that, in the event their tax identification numbers are not

          11. Consent to Jurisdiction and Service. Buyer, the Company and the

               1.3.   Time and Place of Closing.

          The closing of the purchase and sale provided for in this Agreement

parties.

               1.4.   Further Assurances.

          The Members from time to time after the Closing at the request of
Buyer and without further consideration shall execute and deliver further
instruments of transfer and assignment and take such other action as Buyer may
reasonably require to more effectively transfer and assign to, and vest in,
Buyer the Shares and all rights thereto, and to fully implement the provisions

               1.5.   Transfer Taxes.

          All transfer taxes, fees and duties under applicable law incurred in
connection with the sale and transfer of the Purchased Assets and/or Shares
under this Agreement, if any, will be borne and paid by the Company.

               1.6.   Excluded Interests.

          It is the understanding of Buyer and Nextera that the Company prior to
the date hereof had held equity interests in New Med Corporation, Screening
Technologies, Inc. and ReCall Services, Inc. (such equity interests, together
with the contracts and agreements between the Company and such entities,
hereinafter referred to collectively as the "Excluded Interests"). Prior to the
Closing, all Excluded Interests and all related contracts and agreements will be
transferred by the Company to an entity to be formed by the Company (the
"Excluded Entity"). Notwithstanding the purchase by Buyer of the Purchased
Assets and the Shares, the Company and the Members acknowledge and agree that
Buyer and Nextera will not acquire any assets or assume any liabilities
(hereinafter referred to as the "Excluded Liabilities") of the Company or of the
Members associated with or related to the Excluded Interests, including, without
limitation, any liabilities or obligations relating to work performed or to be
performed by the Company. The Members further represent and warrant (i) that the
sole purpose of the Excluded Entity is and shall continue to be holding the
Excluded Interests and to complete existing obligations related to work
performed for the Excluded Interests, (ii) that the Members will not devote any
time to the Excluded Entity other than Michael Martindale who may serve in a
passive oversight role as a director of the Excluded Entity, and (iii) that the
Excluded Entity will not compete directly or indirectly with the business of
Buyer or Nextera.

               1.7.   Holdback Amount.

               (a) Schedule of 1997 Revenue. As soon as practicable following
completion of the audit of the Company's financial statements for the fiscal
year ending December 31, 1997 ("Fiscal 1997"), the Company shall prepare, in
accordance with generally accepted accounting principles, consistent with those
used in the preparation of the Company's Financial Statements (as hereinafter
defined), a schedule of the Company's revenue for Fiscal 1997 (the "Revenue
Schedule") which shall include revenues generated



                                       3
<PAGE>   8

from the Excluded Interests. The aggregate Company revenues shown on the Revenue
Schedule shall be the "1997 Revenue." The Revenue Schedule shall be itemized by
customer and otherwise be in reasonably sufficient detail to identify and
analyze the Company services provided to generate the revenues. The Company
shall deliver the Revenue Schedule to Buyer and the Members promptly following
its completion.

               (b) Distribution of Holdback Amount. In the event that the 1997
Revenue exceeds Nine Million Two Hundred Fifty Thousand Dollars ($9,250,000)
(the "Base Amount"), Buyer shall pay to the Members from the Holdback Amount an
aggregate amount equal to (i) Two Dollars ($2.00), multiplied by (ii) the amount
by which 1997 Revenue exceeds the Base Amount, together with the interest earned
on such amount from the Closing. Any such amounts paid to the Members shall be
allocated among the Members in accordance with their respective interest in the
Holdback Amount as shown on Exhibit A-1 hereto. In no event shall any amounts
payable to the Members under this Section 1.7 exceed the Holdback Amount, plus
interest earned thereon. The amount of the Holdback Amount not so allocated to
the Members, together with interest earned thereon from the Closing, shall be
retained by Buyer. If the 1997 Revenue is less than or equal to the Base Amount,
the Company shall retain the entire Holdback Amount, together with interest
earned thereon.

               (c) Disputes. If Nextera or the Members shall disagree with the
amount of 1997 Revenues shown on the Revenue Schedule, it shall notify the other
in writing of such disagreement within fifteen (15) business days of its receipt
of the Revenue Schedule. If no notice of disagreement is so provided, the
Holdback Amount shall be distributed in accordance with Section 1.7(b) above. If
a disagreement exists, Nextera and the Members shall use their best efforts for
a period of thirty days following the notice of disagreement to resolve any
disagreement. If at the end of such period, Nextera and the Members are unable
to resolve the disagreement, a mutually agreed upon independent public
accounting firm (the "Arbitrator") shall be retained to make a final and binding
determination of 1997 Revenue. The fees and expenses of the Arbitrator shall be
borne equally by Nextera and the Members.

               1.8.   Working Capital. The amount of the cash payments to be
made by Buyer to the Company for the Purchased Assets at the Closing is premised
upon the Company having at least One Million Two Hundred Thousand Dollars
($1,200,000) of working capital, determined in accordance with generally
accepted accounting principles, at the Closing, taking into account all fees and
expenses of the Company related to the transactions contemplated by this
Agreement, accruals for year-end bonuses to the Members and accruals related to
amounts to be paid pursuant to Section 6.2 hereof and without taking into
account items related to the Excluded Investments (such amount being the
"Closing Working Capital"). No later than two business days prior to the
Closing, the Company shall advise Buyer and Nextera of its estimate of Closing
Working Capital. Without limiting other rights that Buyer and Nextera may have
under this Agreement, if the amount so estimated is less than One Million Two



                                       4
<PAGE>   9

Hundred Thousand ($1,200,000), the cash payment to the Company for the Purchased
Assets at Closing shall be reduced by the amount of such shortfall. If the
Closing Working Capital is One Million Two Hundred Thousand Dollars ($1,200,000)
or more, such excess shall become an account payable by the Buyer to the
Members, pro rata among the Members based on their respective ownership interest
in the Company as set forth in Exhibit A-1 (the "Working Capital Payable"). Such
account payable shall be made, without interest, at such time as payment can be
funded from the Company's operations without borrowing under the Company's line
of credit as determined in good faith by Nextera's Board of Directors and in no
event shall payment be made later than June 30, 1998. Within thirty (30) days
following the Closing, the Company shall determine the actual Closing Working
Capital and promptly notify Buyer, Nextera and the Members of such amount. If
such actual Closing Working Capital would have resulted in a different cash
payment to the Company for the Purchased Assets at the Closing or a different
account payable to the Members, Nextera and the Members shall reconcile the
payment discrepancy unless either Nextera or the Members disputes the
determination of actual Closing Working Capital. All such disputes shall be
governed by the same procedures as set forth in Section 1.7(c).

               (a) Real Property. The Company does not own any real property.
All of the real property leased by the Company is identified on Schedule 2.6(a)
(herein referred to as the "Leased Real Property").

                    (i) Leases. All leases of Leased Real Property are
          identified on Schedule 2.6(a), and true and complete copies thereof
          have been delivered to Nextera. Each of said leases has been duly

          and binding and enforceable against the parties thereto. The Company

          the Company has any event occurred which, with notice or the passage
          of time, or both, would give rise to such a default. To the Company's
          knowledge, the other party to each of said leases is not in default
          under any of said leases and there is no event which, with notice or
          the passage of time, or both, would give rise to such a default.

                    (ii) Consents. Except as set forth in Schedule 2.6(a), no
          consent or approval is required with respect to the transactions
          contemplated by this Agreement from the other parties to any lease of
          Leased Real Property or, to the Company's knowledge, from any
          regulatory authority, no filing with any regulatory authority is
          required in connection therewith, and to the extent that any such
          consents, approvals or filings are required, the Company or the
          Members will obtain or complete them before the Closing.

                    (iii) Condition of Leased Real Property. Except as set forth
          in Schedule 2.6(a), to the knowledge of the Company and the Members
          (1) there are no material defects in the physical condition of any
          portion of the Leased Real Property and (2) all such Leased Real
          Property is in good operating condition and repair, has been well
          maintained.

                    (iv) Compliance with the Law. The Company has not received
          any notice from any governmental authority of any violation of any
          law, ordinance, regulation, license, permit or authorization issued
          with respect to the Leased Real Property that has not been heretofore
          corrected. The Company has not received any notice of any real estate
          tax deficiency or assessment and is not aware of any proposed
          deficiency, claim or assessment with respect to any of the Leased Real
          Property, or any pending or threatened condemnation thereof.

the Company is contained in Schedule 2.6(b) hereto. Except as specifically
disclosed in said Schedule or in the Base Balance Sheet (as hereinafter

claims. None of such personal property or assets is subject to any mortgage,
pledge, lien, conditional sale agreement, security title, encumbrance or other
charge except as specifically disclosed in said Schedule or in the 



                                       7
<PAGE>   12

Base Balance Sheet. The personal property listed in Schedule 2.6(b) reflects all
material personal property of the Company. Except as otherwise specified in
Schedule 2.6(b) hereto, all leasehold improvements, furnishings, machinery and
equipment of the Company presently necessary to the conduct of the business of
the Company as such business is currently being conducted are in good repair,
have been well maintained, and comply in all material respects with all
applicable laws, ordinances and regulations, and such machinery and equipment is
in good working order. Neither the Company nor any of the Members has received
notice of any such law, ordinance or regulation which could adversely affect the
Company or its business.

          2.7. Financial Statements.

               (a) The Company has delivered to Nextera the following financial
statements, copies of which are attached hereto as Schedule 2.7: balance sheets
of the Company for its fiscal years ended December 31, 1995 and 1996 and
statements of income, retained earnings and cash flows for the years then ended
(with the exception of a statement of cash flow for the year ended December 31,
1995), and a balance sheet of the Company for the interim period ended September
30, 1997 and a statement of income, retained earnings and cash flows for the

Financial Statements, have been prepared in accordance with generally accepted
accounting principles applied consistently during the periods covered thereby,
and said Financial Statements, present fairly in all material respects the
financial condition of the Company at the dates of said statements and the
results of its operations for the periods covered thereby, and all other
unaudited financial information provided by the Company to Nextera since the
date of the Base Balance Sheet presents fairly and completely in all material
respects the information purported to be shown thereon.

               (b) As of the date of the Base Balance Sheet, the Company did not
have any liabilities of any nature, whether accrued, absolute or contingent
(including without limitation, liabilities as guarantor or otherwise with
respect to obligations of others, liabilities for taxes due or then accrued or
to become due, or contingent or potential liabilities relating to activities of
the Company or the conduct of its business prior to the date of the Base Balance
Sheet), except liabilities stated or adequately reserved against on the Base
Balance Sheet.

               (c) The projected operating results for fiscal year 1997 and the
Company's fiscal year 1998 operating budget which have previously been supplied
by the Company to Nextera have been prepared in good faith on the basis of
assumptions by the Company which the Company believed were reasonable at the
time of the preparation of such projections. It being recognized, however,
without affecting or limiting any other representation or warranty in this
Agreement, that such projections do not constitute any warranty as to the
Company's future performance and that some assumptions may not materialize and
unanticipated events and circumstances may occur subsequent to the date



                                       8
<PAGE>   13


hereof and that therefore actual results may vary materially from projected

limitation, liabilities as guarantor or otherwise with respect to obligations of
others, or liabilities for taxes due or then accrued or to become due or
contingent or potential liabilities relating to activities of the Company or the
conduct of its business prior to the date hereof or the Closing, as the case may
be, regardless of whether claims in respect thereof had been asserted as of such
date), except liabilities (i) stated or adequately reserved against on the Base
Balance Sheet or the notes thereto, or (ii) incurred in the ordinary course of
business of the Company consistent with the terms of this Agreement.

Company has no pending requests for any such waivers, extensions, or comparable
consents.

               (f) No audit or other proceeding by any federal, state, local or
foreign court, governmental, regulatory, administrative or similar authority is

the Company has not received written notice of any pending audits or

               (h) The Company uses the cash method of accounting for income tax
purposes and has not made any change in accounting methods, received a ruling
from any taxing authority or signed an agreement with any taxing authority that

expectation that any taxing authority may claim or assess any additional Taxes
payable by the Company for any period ending on or prior to the Closing Date and

any period ending on or prior to the Closing Date.

               (o) Schedule 2.8 sets forth each state, local and foreign
jurisdiction in which the Company is required, or has been at any time required,

patent or patent application which includes claims that would be infringed by or

          2.24. Employee Benefit Programs.

                (a) Schedule 2.24 lists every Employee Program (as defined
below) that has been maintained (as defined below) by the Company at any time
during the three-year period ending on the date of the Closing.

                (b) Each Employee Program which has ever been maintained by the
Company and which has at any time been intended to qualify under Section 401(a)
of the Code, and each associated trust which at any time has been intended to be
exempt from taxation pursuant to Section 501(a) of the Code is the subject of a
favorable determination, opinion or approval letter from the Internal Revenue
Service ("IRS") regarding its qualification or exemption from taxation, as
applicable, under such section and has, in fact, been qualified or tax exempt,
as applicable, under the applicable section of the Code for all periods for
which the applicable statute of limitations has not expired through and
including the Closing (or, if earlier, the date that all of such Employee
Program's assets were distributed). No event or omission has occurred which
would cause any such Employee Program to lose its qualification under the
applicable Code section.

                (c) The Company does not know and has no reason to know, of any
failure of any party to comply in any material respect with any laws applicable
to the Employee Programs that have been maintained by the Company. With respect
to any Employee Program ever maintained by the Company for all periods for which
the applicable statute of limitations has not expired, there has occurred no
"prohibited transaction," as defined in Section 406 of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA") or Section 4975 of the Code,
or any material violation of, or material breach of any duty under, ERISA or
other applicable law (including, without limitation, any health care
continuation requirements (under part 6 of subtitle B of Title I or ERISA, or
otherwise) or any other tax law requirements, or conditions to favorable tax
treatment, applicable to such plan), which could result, directly or indirectly,
in any taxes,



                                       18
<PAGE>   23


penalties or other liability to the Company, Buyer or Nextera. No litigation,
arbitration, or governmental administrative proceeding (or investigation) or
other proceeding (other than those relating to routine claims for benefits) is
pending or, to the knowledge of the Company, threatened with respect to any
Employee Program.

                (d) Neither the Company nor any Affiliate (as defined below) has
ever (i) maintained any Employee Program which has been subject to Title IV of
ERISA; (ii) maintained any Multiemployer Plan (as defined below); or (iii)
provided health care or any other non-pension benefits to any employees after
their employment is terminated (other than as required by part 6 of subtitle B
of title I of ERISA or benefits that continue for a brief period of time after
termination of employment, for example for the balance of the month in which an
employee terminates, or has ever promised to provide such post-termination
benefits).

                (e) With respect to each Employee Program maintained by the
Company within the three years preceding the Closing, complete and correct
copies of the following documents (if applicable to such Employee Program) have

such Employee Program, and any funding medium for the Employee Program
(including, without limitation, trust agreements) as they may have been amended;
(ii) the most recent IRS determination, opinion or approval letter with respect
to such Employee Program under Code Sections 401 and 501(a), and any
applications for determination or approval subsequently filed with the IRS;
(iii) the three most recently filed IRS Forms 5500, with all applicable
schedules and accountants' opinions attached thereto; (iv) the summary plan
description for such Employee Program (or other descriptions of such Employee
Program provided to employees) and all modifications thereto; (v) any insurance
policy (including any fiduciary liability insurance policy) related to such
Employee Program; (vi) any documents evidencing any loan to an Employee Program
that is a leveraged employee stock ownership plan; and (vii) all other materials
reasonably necessary for Buyer to perform any of its responsibilities with
respect to any Employee Program subsequent to the Closing (including, without
limitation, health care continuation requirements).

                (f) Neither the Company nor any Affiliate has any announced plan
or legally binding commitment to create any additional Employee Program which is
intended to cover employees or former employees of the Company or any Affiliate
(with respect to their relationship with such entities) or to amend or modify
any existing Employee Program which covers or has covered employees or former
employees of the Company or any Affiliate (with respect to their relationship
with such entities).]

                (g) Each Employee Plan listed on Schedule 2.24 may be amended,
terminated, modified or otherwise revised prospectively by the Company including
the elimination of any and all future benefit accruals under any Employee Plan.

                (h) No event has occurred in connection with which the Company,
any Affiliate or any Employee Program, directly or indirectly, could be subject
to any material



                                       19
<PAGE>   24

liability (A) under any statute, regulation or governmental order relating to
any Employee Programs or (B) pursuant to any obligation of the Company or any
Affiliate to indemnify any person against liability incurred under any such
statute, regulation or order as they relate to the Employee Programs.

                (i) Neither the execution and delivery of this Agreement by the
Company nor the consummation of the transactions contemplated hereby will result
in the acceleration or creation of any rights of any person to benefits under
any Employee Program (including, without limitation, the acceleration of the
vesting or exercisability of any stock options, the acceleration of the vesting
of any restricted stock, or the acceleration or creation of any rights under any
severance, parachute or change in control agreement).

                (j) Each Employee Program and related trust agreement or other
funding instrument, as applicable, which covers or has covered employees or
former employees of the Company or any Affiliate (with respect to their
relationship with such entities) is legally valid and binding and in full force
and effect.

                (k) There is no contract, agreement, plan or arrangement
covering any employee or former employee of the Company or any Affiliate (with
respect to its relationship with such entities) that, individually or
collectively, provides for the payment by the Company or any Affiliate of any
amount (i) that is not deductible under Section 162(a)(1) or 404 of the Code or
(ii) that is an "excess parachute payment" pursuant to Section 280G of the Code.

                (l) All contributions required to be made by the Company or any
Affiliate with respect to any Employee Program due as of any date through and
including the Closing Date have been made when due.

                (m) For purposes of this section:

                    (i) "Employee Program" means (A) any employee benefit plan
          within the meaning of ERISA Section 3(3), including, but not limited
          to, any multiple employer welfare arrangement (within the meaning of
          ERISA Section 3(4)), plan to which more than one unaffiliated employer
          contributes and any employee benefit plan (such as a foreign or excess
          benefit plan) which is not subject to ERISA; and (B) any employment,
          consulting, severance or other similar contract, arrangement or
          policy, any stock option plan, bonus or incentive award plan, deferred
          compensation agreement, supplemental income arrangement, vacation
          plan, any employee benefit arrangement described in Code Section
          501(c)(9), and any other employee benefit plan, agreement, and
          arrangement not described in (A) above. In the case of an Employee
          Program funded through a trust described in Code Section 501(a), each
          reference to such Employee Program shall include a reference to such
          trust.

<PAGE>   25


                    (ii) An entity "maintains" an Employee Program if such
          entity sponsors, contributes to, or provides (or has promised to
          provide) benefits under such Employee Program, or has any obligation
          (by agreement or under applicable law) to contribute to or provide
          benefits under such Employee Program, or if such Employee Program
          provides benefits to or otherwise covers employees of such entity, or
          their spouses, dependents, or beneficiaries.

                    (iii) An entity is an "Affiliate" of the Company if it would

          conditions set forth in Section 7.2 of this Agreement have not been

<PAGE>   46

evaluating the merits and risks of his or her sale of equity interests in the

set forth in Schedule 2.7 to this Agreement and such Member hereby represents
that he has not relied upon any representations, warranties or agreements of any
person other than those set forth in this Agreement.

        Such Member acknowledges and agrees that the provisions hereof are
reasonable in context and scope, are a material condition to the Company's
willingness to enter into and effect this Agreement and effect the transactions
contemplated hereby and are intended to be and shall be enforced to the full
extent set forth herein.

SECTION 10. INDEMNIFICATION.

          10.1. Indemnification by the Members.

          The Members jointly and severally agree subsequent to the Closing to
indemnify and hold the Company, Buyer, Nextera, Holdings, and their respective
subsidiaries and affiliates and persons serving as officers, directors,
partners, managers, stockholders, members, employees and agents thereof (other
than the Members, except to the extent of liabilities incurred in their
capacities as such an officer, director or employee after the Closing)
(individually a "Buyer Indemnified Party" and collectively the "Buyer
Indemnified Parties") harmless from and against any damages, liabilities,
losses, taxes, fines, penalties, costs, and expenses (including, without
limitation, reasonable fees of counsel) of any kind or nature whatsoever
(whether or not arising out of third-party claims and including all amounts paid
in investigation, defense or settlement of the foregoing) which may be sustained
or suffered by any of them arising out of or based upon any of the following
matters:

               (a) fraud, intentional misrepresentation or the cause or
knowledge of a deliberate or willful breach of any representations, warranties
or covenants of the Company or the Members under this Agreement or in any
certificate, schedule or exhibit delivered pursuant hereto (collectively, "Fraud
Claims");

               (b) any breach of any representation or warranty of the Members
set forth in Section 2.3 of this Agreement (collectively, "Ownership Claims");

               (c) any liability of the Company or the Members for Taxes arising
from the activities of the Company and all events and transactions on or prior
to the Closing and any breach of the representations and warranties set forth in
Section 2.8 hereof and any covenant with respect to Taxes or tax related matters
(collectively, "Tax Claims");


                                       42
<PAGE>   47

               (d) any liability of the Company, Buyer or Nextera with respect
to the Excluded Interests (collectively, "Excluded Liability Claims"); and

               (e) other than Fraud Claims, Ownership Claims, Tax Claims or
Excluded Liability Claims, any other breach of any representation, warranty or
covenant of the Members under this Agreement or in any schedule or exhibit
delivered pursuant hereto, or by reason of any claim, action or proceeding
asserted or instituted growing out of any matter or thing constituting a breach
of such representations, warranties or covenants (collectively, "General
Claims").

          Each Member severally, but not jointly, agrees subsequent to the
Closing to indemnify and hold all Buyer Indemnified Parties harmless from and
against any damages, liabilities, losses, taxes, fines, penalties, costs, and
expenses (including, without limitation, reasonable fees of counsel) of any kind
or nature whatsoever (whether or not arising out of third-party claims and
including all amounts paid in investigation, defense or settlement of the
foregoing) which may be sustained or suffered by any of them arising out of or
based upon fraud, intentional misrepresentation or any breach (whether or not
deliberate or willful) of any representation or warranty of such Member
contained in Section 3, or by reason of any claim, action or proceeding asserted
or instituted growing out of any matter or thing constituting a breach of such
representation or warranty (collectively, "Individual Claims").

          In the event that an indemnification claim is payable with respect to
a breach of a representation or warranty of the Members under Section 2.9 that
relates to a receivable or unbilled revenue not being enforceable or collectible
or which is subject to set off or counterclaim, the amount payable by the
Members to the Buyer Indemnified Party with respect to such claim shall be
determined as follows:

                    (i) any claim with respect to a receivable or unbilled
          revenues related to Company revenue for 1997 in excess of $10 million
          shall not be the basis for any recovery for breach of Section 2.9;
          provided, however, that such events may still be subject to
          indemnification by the Members to the Buyer Indemnified Party to the
          extent that such event resulted in an overpayment to the Members under
          Section 1.8 or Section 6.2;

                    (ii) for any claim not covered by (i) above, the amount
          payable by the Members to the Buyer Indemnified Party with respect to
          up to $750,000 of such receivables or unbilled revenues shall be twice
          the amount of the receivable or unbilled revenue which is not
          enforceable or collectible or subject to set off or counterclaim,
          together with all other items otherwise subject to indemnification
          under this Section 10.1; and

                    (iii) for any claim not covered by (i) or (ii) above, the
          standard provisions for indemnification set forth in Section 10 shall
          apply.



                                       43
<PAGE>   48

          10.2. Limitations on Indemnification by the Members.

          Anything contained in this Agreement to the contrary notwithstanding,
the liability of the Members to provide any indemnification to any Buyer
Indemnified Party and right of Buyer Indemnified Parties to indemnification
under Section 10.1 shall be subject to the following provisions:

               (a) No claims for indemnification shall be made under this
Agreement against any Member, and no indemnification shall be payable to any
Buyer Indemnified Party, with respect to General Claims after the date which is
eighteen (18) months following the Closing.

               (b) No claims for indemnification shall be made under this
Agreement against any Member, and no indemnification shall be payable to any
Buyer Indemnified Party, with respect to any Tax Claim after expiration of all
applicable statute of limitations with respect to the Tax that is the subject of
the indemnification claim and the expiration of all applicable statutes of
limitation with respect to collection of the Tax.

               (c) The aggregate amount to be payable to all Buyer Indemnified
Parties for claims for indemnification with respect to General Claims shall in
no event exceed Five Million Dollars ($5,000,000).

               (d) The amount to be payable by a Member to all Buyer Indemnified
Parties for claims for indemnification hereunder shall in no event exceed such
Member's pro rata share of the total amount to be paid to all Buyer Indemnified
Parties for claims for indemnification hereunder. The pro rata shares of the
Members for this purpose shall be the same percentages as the Members respective
ownership interests in the Company as set forth on Exhibit A-1.

               (e) In the event that any claim for indemnification arises from a
breach of representation, warranty or covenant which was made or undertaken by a
Member, by the express terms of this Agreement severally and not jointly, the
Members shall be severally, but not jointly, liable for indemnification in
respect of such a claim.

               (f) The Members shall have no obligation for indemnification with
respect to General Claims hereunder until aggregate claims for indemnification
with respect to General Claims hereunder exceed $50,000, in which case the
Members shall be obligated for indemnification of all General Claims including
the initial $50,000 of such claims.

               (g) Claims for indemnification with respect to Fraud Claims,
Ownership Claims, Tax Claims or Excluded Liability Claims made under this
Agreement by any Buyer Indemnified Party shall not be subject to any of the
limitations set forth in this Section 10.2 other than Section 10.2(b).

          10.3. Indemnification by Nextera. Nextera agrees to indemnify and hold
the Members (individually a "Member Indemnified Party" and collectively the
"Member Indemnified Parties") harmless from and against any damages,
liabilities, losses and expenses (including,





                                       44
<PAGE>   49

without limitation, reasonable fees of counsel) of any kind or nature whatsoever
(whether or not arising out of third-party claims and including all amounts paid
in investigation, defense or settlement of the foregoing) which may be sustained
or suffered by any of them arising out of or based upon any breach of any
representation, warranty or covenant made by Nextera in this Agreement or in any
certificate delivered by Nextera hereunder, or by reason of any claim, action or
proceeding asserted or instituted growing out of any matter or thing
constituting such a breach.

          10.4. Limitation on Indemnification by Nextera. Notwithstanding the
foregoing, (a) no indemnification shall be payable to the Members with respect
to claims asserted pursuant to Section 10.3 above after the date which is
eighteen (18) months after the Closing and the aggregate amount to be payable to
Members pursuant to Section 10.3 shall not exceed Five Million Dollars
($5,000,000) and (b) Nextera shall have no obligation for indemnification
hereunder until aggregate claims for indemnification hereunder exceed $50,000,
in which case Nextera shall be obligated for indemnification of all claims,
including the initial $50,000 of such claims; provided, however, that the
limitations set forth herein shall not apply to a claim for indemnification
based upon a breach of Section 5.2 or 5.3 or covenants to be performed
post-Closing. Claims for indemnification with respect to fraud, intentional
misrepresentation or the cause or knowledge of a deliberate or willful breach of
any representations, warranties or covenants of Nextera under this Agreement or
in any certificate, schedule or exhibit delivered pursuant hereto made under
this Agreement by any Member Indemnified Party shall not be subject to any of
the limitations set forth in this Section 10.4.

          10.5. Notice; Defense of Claims. An indemnified party shall make
claims for indemnification hereunder by giving written notice thereof to the
indemnifying party within the period in which indemnification claims can be made
hereunder. If indemnification is sought for a claim or liability asserted by a
third party, the indemnified party shall also give written notice thereof to the
indemnifying party promptly after it receives notice of the claim or liability
being asserted, but the failure to do so shall not relieve the indemnifying
party from any liability except to the extent that it is prejudiced by the
failure or delay in giving such notice. Such notice shall summarize the bases
for the claim for indemnification and any claim or liability being asserted by a
third party. Within 20 days after receiving such notice the indemnifying party
shall give written notice to the indemnified party stating whether it disputes
the claim for indemnification and whether it will defend against any third party
claim or liability at its own cost and expense. If the indemnifying party fails
to give notice that it disputes an indemnification claim within 20 days after
receipt of notice thereof, it shall be deemed to have accepted and agreed to the
claim, which shall become immediately due and payable. The indemnifying party
shall be entitled to direct the defense against a third party claim or liability
with counsel selected by it (subject to the consent of the indemnified party,
which consent shall not be unreasonably withheld) as long as the indemnifying
party is conducting a good faith and diligent defense. The indemnified party
shall at all times have the right to fully participate in the defense of a third
party claim or liability at its own expense directly or through counsel;
provided, however, that if the named parties to the action or proceeding include
both the indemnifying party and the indemnified party and the indemnified party
is advised that representation of both parties by the same counsel would be
inappropriate under applicable standards of professional conduct, the
indemnified party may engage separate counsel at the expense of the indemnifying
party. If no such notice of intent to




                                       45

<PAGE>   50

dispute and defend a third party claim or liability is given by the indemnifying
party, or if such good faith and diligent defense is not being or ceases to be
conducted by the indemnifying party, the indemnified party shall have the right,
at the expense of the indemnifying party, to undertake the defense of such claim
or liability (with counsel selected by the indemnified party), and to compromise
or settle it, exercising reasonable business judgment. If the third party claim
or liability is one that by its nature cannot be defended solely by the
indemnifying party, then the indemnified party shall make available such
information and assistance as the indemnifying party may reasonably request and
shall cooperate with the indemnifying party in such defense, at the expense of
the indemnifying party.

          10.6. Satisfaction of Member Indemnification Obligations. In order to
satisfy the indemnification obligations of the Members hereunder, a Buyer
Indemnified Party shall proceed first directly against the Escrow Deposit as
further set forth in the Escrow Agreement and then directly against the Members,
subject to the limitations set forth in Section 10.2(c) and (d), as applicable.
As further set forth in the Escrow Agreement, all claims against the Escrow
Amount shall be satisfied first against the cash portion thereof and then
against the Nextera Class A Units.

SECTION 11. MISCELLANEOUS.

          11.1. Fees and Expenses.

          Each of the parties will bear its own expenses in connection with the
negotiation and the consummation of the transactions contemplated by this
Agreement.

          11.2. Governing Law.

          This Agreement shall be construed under and governed by the internal
laws of the Commonwealth of Massachusetts without regard to its conflict of laws
provisions.

          11.3. Notices.

          Any notice, request, demand or other communication required or
permitted hereunder shall be in writing and shall be deemed to have been given
if delivered or sent by facsimile transmission, upon receipt, or if sent by
registered or certified mail, upon the sooner of the date on which receipt is
acknowledged or the expiration of three days after deposit in United States post
office facilities properly addressed with postage prepaid. All notices to a
party will be sent to the addresses set forth below or to such other address or
person as such party may designate by notice to each other party hereunder:

          11.4. Entire Agreement. This Agreement, including the Schedules and
Exhibits hereto, reflects the entire agreement of the parties with respect to

commitments and writings. No promises, representations, understandings,
warranties and agreements have been made by any of the parties hereto except as
referred to herein or in such Schedules and Exhibits; and all inducements to the
making of this Agreement relied upon by either party hereto have been expressed

controlled by or under common control with Buyer or Nextera upon written notice

          11.6. Captions and Gender. The captions in this Agreement are for
convenience only and shall not affect the construction or interpretation of any
term or provision hereof. The use in this Agreement of the masculine pronoun in
reference to a party hereto shall be deemed to include the feminine or neuter,
as the context may require.

          11.7. Execution in Counterparts. For the convenience of the parties
and to facilitate execution, this Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which shall
constitute one and the same document.

          11.8. Amendments. This Agreement may not be amended or modified, nor
may compliance with any condition or covenant set forth herein be waived, except
by a writing duly and validly executed by each party hereto, or in the case of a
waiver, the party waiving compliance.

          11.9. Publicity and Disclosures. No press releases or public
disclosure, either written or oral, of the transactions contemplated by this
Agreement, shall be made by a party to this Agreement without the prior
knowledge and written consent of Nextera and the Company.

          11.10. Specific Performance. The parties agree that it would be
difficult to measure damages which might result from a breach of this Agreement
by the Company or the Members and that money damages would be an inadequate
remedy for such a breach. Accordingly, if there is a breach or proposed breach
of any provision of this Agreement by the Company or the Members, and Nextera
does not elect to terminate under Section 8, Nextera shall be entitled, in
addition to any other remedies which it may have, to an injunction or other
appropriate equitable relief to restrain such breach without having to show or
prove actual damage to Nextera.

                                                                EXHIBIT NO. 10.5


                                ESCROW AGREEMENT

          This Escrow Agreement (the "Agreement") is entered into as of January
5, 1998 by and among SGM Consulting, L.L.C., a Delaware limited liability
company ("Buyer"), Nextera Enterprises, L.L.C., a Delaware limited liability
company and the controlling member of Buyer ("Nextera"), Nextera Enterprises
Holdings, L.L.C., a Delaware limited liability company and the controlling
member of Nextera ("Holdings"), SiGMA Consulting, LLC, a New York limited
liability company (the "Company"), the holders of the Company's membership
interests listed on Exhibit A attached hereto (herein collectively referred to
as the "Members" and individually as a "Member") and Chase Manhattan Trust
Company, National Association, as escrow agent (the "Escrow Agent").

          WHEREAS, pursuant to a Purchase Agreement (the "Purchase Agreement")
dated as of January 5, 1998 by and among Buyer, Nextera, Holdings, the Company
and the Members, Buyer is purchasing certain assets from the Company and
acquiring all of the issued and outstanding membership interests of the Company
from the Members; and

          WHEREAS, the Members have agreed to indemnify Buyer and Nextera
against certain breaches of the representations, warranties and covenants made
by the Company and the Members in the Purchase Agreement and against certain
other matters as specified in Section 10 of the Purchase Agreement; and

          WHEREAS, to secure payment of the Members' indemnification
obligations, EIGHT HUNDRED FIFTY THOUSAND DOLLARS ($850,000) in cash (the
"Escrowed Cash") and 200,000 Nextera Class A Units (the "Escrowed Units")
(together, the Escrowed Cash and the Escrowed Units and additions to or earnings
on the same, the "Escrow Deposit") are being deposited, pursuant to Section 1.2
of the Purchase Agreement, in escrow to be held as hereinafter provided.

          NOW, THEREFORE, in consideration of the foregoing and the mutual
promises of the parties herein contained, and other good and valuable
consideration, receipt and sufficiency of which is hereby acknowledged, the
parties hereto agree as follows:

          1. Establishment of Escrow: Investment. Buyer has herewith deposited
the Escrow Deposit with the Escrow Agent on the date of the Closing. The
Escrowed Units have been issued in the names of the Members who, subject to the
provisions herein, have the right to receive such shares, as set forth on
Exhibit A attached hereto, and shall be accompanied by stock powers or similar
instruments duly signed in blank by the appropriate Member. The Escrow Deposit
shall be held in escrow in an account designated as the SiGMA Consulting, LLC
Escrow Account or an account having such other similar designation, subject to
the terms and conditions set forth herein. Jacob H. Brooks shall serve as the
exclusive representative of the Members with respect to the Escrow Deposit and
this Agreement (the "Escrow Representative"). If, for any reason, the Escrow
Representative shall be either unable or unwilling to serve, a successor Escrow
Representative shall be appointed by written consent of all Members and all
references to the Escrow Representative shall be deemed to include such
successor. The Escrow Agent shall

invest all cash held as part of the Escrow Deposit only in such specific
investments as Buyer and the Escrow Representative shall from time to time
jointly direct in writing to the Escrow Agent; provided, however, that such
investments shall be limited to:

               (a)    time deposits, certificates of deposit and acceptances,
                      maturing within ninety (90) days from the date of
                      acquisition thereof, issued by national banks located in
                      the United States of America, including the Escrow Agent
                      or any of its affiliates, and having capital, surplus and
                      profits aggregating at least one hundred million dollars
                      ($100,000,000);

               (b)    securities or other obligations of, or guarantee by, the
                      United States of America or any agency thereof having
                      maturities of not greater than one (1) year;

               (c)    commercial paper rated A-1 or P-1 by Standard & Poor's or
                      Moody's Investors Service;

               (d)    repurchase agreements fully collateralized by obligations
                      described in clauses 1(a), 1(b) or 1(c) hereof;

               (e)    shares of investment companies registered under the
                      Investment Company Act of 1940 which invest in any
                      obligation described herein, or shares of the Dreyfus Cash
                      Management Plus Money Market Fund, including those for
                      which the Escrow Agent or any of its affiliates provide
                      services for a fee, whether as an investment advisor,
                      custodian, transfer agent, registrar, sponsor,
                      distributor, manage or otherwise.

          Until further written notice, cash in the Escrow Deposit shall be
invested in Dreyfus Cash Management Plus. Unless otherwise directed in writing
by the Escrow Representative and Buyer, the Escrow Agent shall not invest all or
any portion of the Escrow Deposit in any investment if the maturity date of such
investment is later than the Termination Date (as defined below).

          2. Amounts Earned on Escrow Deposit: Tax Matters. All amounts earned,
paid or distributed with respect to the Escrow Deposit (whether interest,
dividends, distributions from Nextera with respect to the Escrowed Units or
otherwise) shall become a part of the Escrow Deposit, shall be held hereunder
upon the same terms as the original Escrow Deposit and shall be distributed
together with the underlying portion of the original Escrow Deposit pursuant to
the terms of this Agreement. The parties agree that to the extent permitted by
applicable law, including Section 468B(g) of the Internal Revenue Code of 1986,
as amended, the Members will include all amounts earned on the Escrow Deposit in
their gross income for federal, state and local income tax (collectively,
"income tax") purposes and pay any income tax resulting therefrom.

          3. Claims Against Escrow Deposit.


                                       2
<PAGE>   3

               (a) At any time or times prior to the expiration of this
Agreement, Buyer may make claims against the Escrow Deposit for indemnification
pursuant to and in accordance with Section 10 of the Purchase Agreement. Buyer
shall notify the Escrow Representative and the Escrow Agent in writing prior to
the expiration of this Agreement of each such claim, including a summary of the
amount of and bases for such claim. If the Escrow Representative shall dispute
such claim, the Escrow Representative shall give written notice thereof to Buyer
and to the Escrow Agent within twenty (20) days after receipt of notice of
Buyer's claim, in which case the Escrow Agent shall continue to hold the Escrow
Deposit in accordance with the terms of this Agreement; otherwise, such claim
shall be deemed to have been acknowledged to be payable out of the Escrow
Deposit in the full amount thereof and the Escrow Agent shall use its best
efforts to pay such claim to Holdings within three (3) business days after
expiration of said twenty day period or as soon thereafter as possible. If the
amount of the claim exceeds the value of the Escrow Deposit, the Escrow Agent
shall have no liability or responsibility for any deficiency.

               (b) The Escrow Agent shall follow the procedure below in making
any payment in satisfaction of a claim against the Escrow Deposit:

                   (i) The Escrow Agent shall make such payment first from the
Escrowed Cash and any additions to or earnings on the Escrowed Cash until all
cash in the Escrow Deposit has been exhausted.

                   (ii) To the extent that any claim exceeds the amount of
Escrowed Cash or other cash in the Escrow Deposit, the Escrow Agent shall make
payment from the Escrowed Units in such number of Escrowed Units (computed to
the nearest whole unit) having a value equal to the value of the claim not
satisfied by cash payment. Any payment of Escrowed Units by the Escrow Agent to
Holdings shall be treated as a sale by the Members of such Escrowed Units for
the value described herein. The value of an Escrowed Unit for purposes of the
Section shall be the fair market value of such unit on the date of the claim as
determined by the Board of Directors of Nextera (the "Board"). The fair market
value shall be determined in good faith by the Board and the Board shall notify
the Escrow Representative and Escrow Agent in writing of its determination (the
"Valuation Notice"). If the Escrow Representative disputes the fair market value
of the Escrowed Units as determined by the Board, then the Escrow Representative
shall so notify the Board and Escrow Agent in writing (the "Appraisal Notice")
within five (5) business days of receipt of the Valuation Notice. Within fifteen
(15) business days of the receipt of the Appraisal Notice, the Board and the
Escrow Representative shall each appoint a professional appraiser to determine
the fair market value of the Escrowed Units. Each appraiser shall have at least
five (5) years experience in appraising companies similar to Nextera. The two
appraisers shall within the succeeding twenty (20) day period after their
selection, attempt to reach agreement on the fair market value. If the
appraisers reach such agreement they shall so notify the Escrow Agent and their
agreement shall be final and binding on Buyer, Nextera, Holdings, the Board, the
Company, the Escrow Representative, the Members,





                                       3
<PAGE>   4

and their affiliates. If the appraisers fail to agree, they shall within ten
(10) days thereafter select a third appraiser with the same qualification
requirements, and the three (3) appraisers shall establish the fair market value
by majority vote within the succeeding twenty (20) day period and shall notify
the Escrow Agent of their determination. Such determination of the fair market
value shall be final and binding on Buyer, Nextera, Holdings, the Board, the
Company, the Escrow Representative, the Members, and their affiliates. In all
events, the appraisers selected shall be unaffiliated with and otherwise
independent of Buyer, Nextera, Holdings, the Board, the Company, the Escrow
Representative, the Members, and their affiliates. If the fair market value of
the Escrowed Units, as determined by the appraisers, is less than or no more
than five percent (5%) greater than the value as determined by the Board, then
the Members shall pay all costs associated with the appraisers. If the fair
market value as determined by the appraisers is more than five percent (5%)
greater than the value as determined by the Board, then Buyer shall pay for all
costs associated with the appraisers. The Escrowed Units delivered to Holdings
in satisfaction of a claim shall be allocated among the Members so as to reduce
each Member's interest in the remaining Escrowed Units by an equal proportion.
In the event that the Escrow Agent must make payment with a number of units less
than or different from the number of units represented by a certificate in the
Escrow Deposit, the Escrow Agent shall surrender such certificate to Nextera and
Nextera shall issue to the Escrow Agent certificates of Nextera Class A Units
identical in form but for the number of units as necessary to allow for proper
payment of the claim so long as the number of units of the new certificates plus
the amount of units used to satisfy such claim shall be equivalent to the total
number of units covered by the surrendered certificate.

          4. Disputed Claims.

               (a) If the Escrow Representative shall dispute an indemnification
claim of Buyer as above provided, the Escrow Agent shall set aside a portion of
the Escrow Deposit sufficient to pay said claim in full (the "Set Aside
Amount"). If Buyer notifies the Escrow Agent in writing that it has made
out-of-pocket expenditures in connection with any such disputed claim, and
provides paid receipts for such expenditures, in addition to expenditures
included in the Set Aside Amount, an amount equal to such additional
expenditures shall be added to the Set Aside Amount.

               (b) If the disputed indemnification claim has not been resolved
or compromised within sixty (60) days after the Escrow Representative sends
notice of dispute of the same, or in the event of a third-party claim or suit,
within fifteen (15) days after its resolution or compromise, said
indemnification claim shall be referred to the American Arbitration Association,
to be settled by binding arbitration in Boston, Massachusetts, in accordance
with the commercial arbitration rules of the Association. The fees and expenses
of the arbitrator shall be borne equally by the Members and Buyer. In no event
shall the Escrow Agent be responsible for any fee or expense of any party to any
arbitration proceeding. The determination of the arbitrator as to the amount, if
any, of the indemnification claim which is properly allowable shall be
conclusive and binding upon the parties hereto and judgment may be entered
thereon in any court having jurisdiction thereof, including, without limitation,
any Superior Court in the Commonwealth of Massachusetts. The arbitrator shall
have the authority to award to the prevailing party reasonable costs and
expenses including attorney's fees and the cost of arbitration. The Escrow Agent
shall use its best efforts to make payment of such claim, as and to the extent
allowed, to Buyer out of the Set Aside Amount (or if insufficient, out of the
Escrow Deposit) within three (3) business days following said determination or
as soon thereafter as possible.

               (c) Notwithstanding Section 4(b), if a disputed indemnification
claim has not been resolved or compromised as of the Termination Date (as
hereinafter defined), and such claim




                                       4

does not involve a third-party claim or suit, Buyer and the Escrow
Representative shall continue to negotiate in good faith a settlement of such
claims for a period of ten (10) days. If, after the expiration of such ten-day
period, such indemnification claim still has not been resolved or compromised,
such claim shall be settled in accordance with the arbitration provisions set
forth in Section 4(b).

               (d) It is understood and agreed that should any dispute arise
under this Section 4, the Escrow Agent, upon receipt of written notice of such
dispute or claim by the Escrow Representative, is authorized and directed to
retain in its possession without liability to anyone, the Set Aside Amount
relating to such dispute plus any expenditures of Buyer made pursuant to Section
4(a) until such dispute shall have been settled pursuant to this Section 4. The
Escrow Agent may, but shall be under no duty whatsoever to, institute or defend
any legal proceedings which relate to the Escrow Deposit.

          5. Termination.

               (a) If the Escrowed Cash has not been reduced to zero as of the
date that is eighteen (18) months following the date of this Agreement and there
are no outstanding indemnification claims as of such date, the Escrow Agent
shall distribute the Escrowed Cash to the Members in accordance with their pro
rata interest therein as set forth on Exhibit A attached hereto; otherwise, the
Escrow Agent shall distribute the Escrowed Cash to the Members when all
indemnification claims made by Buyer or Nextera before the date that is eighteen
(18) months following the date of this Agreement pending as of such date have
been resolved.

               (b) This Agreement shall terminate on the date that the Escrow
Deposit is reduced to zero as the result of payments by the Escrow Agent to
Holdings in accordance with the provisions of Section 3 or Section 4. If,
however, the Escrow Deposit has not been reduced to zero as of the date that is
three (3) years following the date of this Agreement (the "Termination Date")
and there are no outstanding indemnification claims on the Termination Date,
this Agreement shall terminate and the Escrow Agent shall distribute the amount
remaining in the Escrow Deposit to the Members in accordance with their pro rata
interest in the Escrow Deposit as set forth in Exhibit A attached hereto;
otherwise this Agreement shall continue in effect until all indemnification
claims Buyer has made pursuant to Section 3 hereof on or prior to the
Termination Date shall have been disposed of. As of the Termination Date, an
amount of the Escrow Deposit adequate to cover all disputed and undisputed
claims made by Buyer pursuant to Section 3 hereof, plus an additional twenty
percent (20%) of any such amount to cover expenses of Buyer associated with such
claims, will be held by the Escrow Agent, and the Escrow Agent shall distribute
on the Termination Date the balance, if any, of the Escrow Deposit to the
Members in accordance with their pro rata interest in the Escrow Deposit as set
forth in Exhibit A attached hereto. At such time as all remaining
indemnification claims hereunder have been resolved and the Escrow Agent has
received a written notice executed by Buyer and the Escrow Representative, or
notification of a determination of an arbitrator pursuant to Section 4(b), to
that effect and any amounts to be distributed to Holdings in connection
therewith have been so distributed, the Escrow Agent shall distribute the
remaining Escrow Deposit, if any, to the Members in accordance with their pro
rata interest in the Escrow Deposit as set forth in Exhibit A attached hereto.

               6. The Escrow Agent.

               (a) Direction from Buyer and Escrow Representative.
Notwithstanding anything herein to the contrary, the Escrow Agent shall promptly
dispose of all or any part of the Escrow Deposit as directed by a writing signed
by Buyer and Escrow Representative.

               (b) Reliance by Escrow Agent; Liability of Escrow Agent. The
Escrow Agent shall be protected in acting upon any written notice, request,
waiver, consent, certificate, receipt, authorization or other paper or document
that the Escrow Agent believes to be genuine and what it purports to be. The
Escrow Agent may confer with its own corporate or outside legal counsel in the
event of any dispute or question as to the construction of any of the provisions
hereof, or its duties hereunder, and shall incur no liability and shall be fully
protected in acting in accordance with the written opinions of such counsel. The
duties of the Escrow Agent hereunder will be limited to the observance of the
express provisions of this Agreement. Except with respect to capitalized terms
used herein and defined in the Purchase Agreement, the Escrow Agent will not be
subject to, or be obliged to recognize, any other agreement between the parties
hereto or directions or instructions not specifically set forth as provided for
herein. The Escrow Agent will not make any payment or disbursement from or out
of the Escrow Deposit that is not expressly authorized pursuant to this
Agreement. The Escrow Agent may rely upon and act upon any instrument received
by it pursuant to the provisions of this Agreement that it reasonably believes
to be genuine and in conformity with the requirement of this Agreement. The
Escrow Agent undertakes to use the same degree of care and skill in performing
its services hereunder as an ordinary prudent person would do or use under the
circumstances in the conduct of his or her own affairs. The Escrow Agent will
not be liable for any action taken or not taken by it under the terms hereof in
the absence of breach of its obligations hereunder or gross negligence or
willful misconduct on its part.

               (c) Indemnification of Escrow Agent. Buyer and the Members will
jointly and severally indemnify and hold the Escrow Agent harmless from and
against any and all losses, costs, damages or expenses (including, but not
limited to, reasonable attorneys' fees) it may sustain by reason of its service
as Escrow Agent hereunder, except such losses, costs, damages or expenses
(including, but not limited to, reasonably attorneys' fees) incurred by reason
of acts or omissions for which the Escrow Agent is liable or responsible under
the last sentence of Section 6(b) hereof.

               (d) Fees and Expenses of the Escrow Agent. All fees of the Escrow
Agent for its services hereunder, together with any expenses reasonably incurred
by the Escrow Agent in connection with this Agreement, shall be shared equally
by Buyer on the one hand and the Members on the other. The fees to be paid by
the Members shall be reduced pro rata from the Members' individual interest in
the Escrow Deposit.

               (e) Resignation and Removal of Escrow Agent. Successor Escrow
Agent.

                    (i) The Escrow Agent may resign from its duties hereunder by
giving each of the parties hereto not less than thirty (30) days prior written
notice of the effective date of such resignation (which effective date shall be
at least thirty (30) days after the date such notice is





                                       6

given). In addition, the Escrow Agent may be removed and replaced on a date
designated in a written instrument signed by Buyer and the Members and delivered
to the Escrow Agent. The parties hereto intend that a successor escrow agent
mutually acceptable to the Escrow Representative and Buyer will be appointed to
fulfill the duties of the Escrow Agent hereunder for the remaining term of this
Agreement in the event of the Escrow Agent's resignation or removal. Upon the
effective date of such resignation or removal, the Escrow Agent shall deliver
the property comprising the Escrow Deposit to such successor escrow agent,
together with an accounting of the investments held by it and all transactions
related to this Agreement, including any distributions made and such records
maintained by the Escrow Agent in connection with its duties hereunder and other
information with respect to the Escrow Deposit as such successor may reasonably
request. If on or before the effective date of such resignation or removal, a
successor escrow agent has not been appointed, the Escrow Agent will thereupon
deposit the Escrow Deposit into the registry of a court of competent
jurisdiction.

                              Upon written acknowledgment by a successor escrow
agent appointed in accordance with this Section 6(e)(i) of its agreement to
serve as escrow agent hereunder and the receipt of the property then comprising
the Escrow Deposit, the Escrow Agent shall be fully released and relieved of all
duties, responsibilities and obligations under this Agreement, except for those
arising under the last sentence of Section 6(b) of this Agreement, and such
successor escrow agent shall for all purposes hereof be the Escrow Agent.

                    (ii) Any corporation, association or other entity into which
the Escrow Agent may be converted or merged, or with which it may be
consolidated, or to which it may sell or otherwise transfer all or substantially
all of its corporate trust business, or any corporation, association or other
entity resulting from any such merger, conversion, consolidation, sale or other
transfer, shall, ipso facto, be and become successor Escrow Agent hereunder,
vested with all of the powers, discretions, immunities, privileges and all other
matters as was its predecessor, without the execution or filing of any
instrument or any further act on the part or any of the parties hereto, anything
herein to the contrary notwithstanding.

          7. Voting of Escrowed Units. So long as any Escrowed Units are
retained by the Escrow Agent, each Member shall be entitled to exercise the
voting power, if any, with respect to that Member's proportional ownership of
the Escrowed Units.

          8. Governing Law. IT IS THE PARTIES' INTENT THAT THIS AGREEMENT SHALL
BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE
COMMONWEALTH OF MASSACHUSETTS (WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF
LAW).

          9. Counterparts. This Escrow Agreement may be executed in one or more
counterparts, all of which documents shall be considered one and the same
document.

          10. Notices. Any notice or other communication required or permitted
hereunder shall be in writing and shall be deemed to have been given when
received, if personally delivered or sent by facsimile transmission, or three

          11. Certification of Tax Identification Number. The parties hereto
agree to provide the Escrow Agent with a certified tax identification number by
signing and returning a Form W-9 (or Form W-8, in the case of non-U.S. persons)
to the Escrow Agent prior to the date on which any income earned on the
investment of the Escrow Deposits is credited to such Escrow Deposits. The
parties hereto understand that, in the event their tax identification numbers

without the express written consent of the parties hereto. No course of conduct
shall constitute a waiver of any of the terms and conditions of this Escrow
Agreement, unless such waiver is specified in writing, and then only to the
extent so specified. A waiver of any of the terms and conditions of this Escrow
Agreement on one occasion shall not constitute a waiver of the other terms of
this Escrow Agreement, or of such terms and conditions on any other occasion.

          14. Reproduction of Documents. This Agreement and all documents
relating thereto, including, without limitation, (a) consents, waivers and
modifications which may hereafter be executed, and (b) certificates and other
information previously or hereafter furnished, may be reproduced by a
photographic, photostatic, microfilm, optical disk, micro-card, miniature

regular course of business, and that any enlargement, facsimile or further
reproduction of such reproduction shall likewise be admissible in evidence.

                               PURCHASE AGREEMENT



        This Purchase Agreement (the "Agreement") is entered into as of March
31, 1998 by and among Nextera Enterprises, L.L.C., a Delaware limited liability
company ("Buyer"), Pyramid Imaging, Inc., a California corporation (the
"Company"), the holders of the Company's capital stock (identified on Exhibit A
as and herein collectively referred to as the "Holders" and individually as a
"Holder").



                               W I T N E S S E T H

        WHEREAS, the Holders own of record and beneficially all of the issued
and outstanding capital stock of the Company, consisting of 4,009,971 shares of
Common Stock (said shares referred to herein as the "Shares");

        WHEREAS, the Excluded Optionholders (as hereinafter defined) and Charles
Blackburn hold options to purchase shares of Common Stock of the Company, as
more fully described in Section 2.3(b);

        WHEREAS, the Holders desire to sell all of the Shares to Buyer, and
Buyer desires to acquire all of the Shares;

        WHEREAS, Buyer desires to issue membership interests pursuant to, and
subject to the terms and conditions of, this Agreement; and

        NOW, THEREFORE, in order to consummate said purchase and sale and in
consideration of the mutual agreements set forth herein, the parties hereto
agree as follows:

SECTION 1. SALE OF SHARES, CANCELLATION OF OPTIONS AND PURCHASE PRICE.

        1.1. Cancellation of Options. At the Closing (as hereinafter defined),
all outstanding options to purchase Common Stock of the Company shall be
canceled. Charles Blackburn and all other holders of options to purchase equity
securities of the Company (such other holders of options are identified on
Exhibit B as and referred to herein as "Excluded Optionholders") shall enter
into an Option Cancellation Agreement in the form attached hereto as Exhibit B
with the Company whereby each such optionholder shall agree to have the Company
cancel all options held by such optionholder.


<PAGE>   6

        1.2. Contribution of Company Shares.

               (a) Transfer of Shares. At the Closing (as hereinafter defined),
each Holder shall deliver or cause to be delivered to Buyer certificates
representing all of the Shares owned by such Holder, as set forth on Exhibit A.
Such certificates shall be presented with assignments duly executed in blank (or
the equivalent), with such other documents as may reasonably be required by
Buyer to effect a valid transfer of such Shares by such Holder, free and clear
of any and all liens, encumbrances, charges or claims.

               (b) Contribution of Shares and Exchange of Buyer Interest. In
return for the contribution from the Holders to Buyer of the Shares and the
cancellation by the Company of the outstanding options to purchase Common Stock
of the Company and in reliance upon the representations and warranties of the
Company and the Holders herein contained and made at the Closing and subject to
the satisfaction of all of the conditions contained herein, Buyer agrees that at
the Closing, it will (a) deliver to the Holders Eight Million Ninety-One
Thousand Six Hundred Sixty Seven Dollars ($8,091,667) in cash and 520,667 Class
A Common Units of Buyer ("Buyer Class A Units") issued pursuant to the Limited
Liability Company Agreement of Nextera Enterprises, L.L.C. dated as of April 9,
1997, as amended on January 6, 1998 (the "Buyer Operating Agreement"), which
shall be distributed in the amounts set forth opposite the name of each Holder
on Exhibit A subject to reductions as provided in Section 1.6 and reductions for
requirements with respect to withholdings under tax or employment laws (the cash
payment to be made by bank cashier's check in Boston Clearing House funds or by
wire transfer of immediately available funds), and (b) deliver to the Escrow
Agent Eight Hundred Twenty Five Thousand Dollars ($825,000) in cash and 66,000
Buyer Class A Units (the "Escrowed Units," together with the Escrowed Cash, the
"Escrow Deposit") to be held by the Escrow Agent pursuant to and in accordance
with the terms of the Escrow Agreement to be executed substantially in the form
attached hereto as Exhibit C.

        1.3. Time and Place of Closing. The closing of the purchase and sale
provided for in this Agreement (herein called the "Closing") shall be held at a
mutually agreeable location in San Francisco, California on April 7, 1998 or at
such other date and location as may be mutually agreed upon by the parties. The
Agreement shall be effective as of March 31, 1998 for all purposes.

        1.4. Further Assurances. The Holders from time to time after the Closing
at the request of Buyer and without further consideration shall execute and
deliver further instruments of transfer and assignment and take such other
action as Buyer may reasonably require to more effectively transfer and assign
to, and vest in, Buyer the Shares and all rights thereto, and to fully implement
the provisions of this Agreement. From time to time after the Closing, Buyer
shall




<PAGE>   7

execute and deliver further instruments and take such other action as the
Holders may reasonably request to confirm or perfect or otherwise to carry out
the transactions contemplated hereby.

        1.5. Transfer Taxes. All transfer taxes, fees and duties under
applicable law incurred in connection with the sale and transfer of the Shares
under this Agreement, if any, will be borne and paid by the Holders.

        1.6. Working Capital.

               (a) Working Capital Payable. The amount of the cash payments to
be made by Buyer to the Company at the Closing is premised upon the Company
having at least Five Hundred Fifty Thousand Dollars ($550,000) of net working
capital (current assets less current liabilities), determined in accordance with
generally accepted accounting principles, at the Closing (such amount being the
"Minimum Working Capital"), provided, however, that such calculation of $550,000
of working capital shall not take into account any accruals by the Company as of
the Closing of any payroll taxes and similar charges paid by the Company
relating to the compensation deemed to be received as a result of cancellation
of outstanding options to purchase Common Stock of the Company. No later than
two business days prior to the Closing, the Company shall advise Buyer of its
estimate of working capital at the Closing. Without limiting other rights that
Buyer may have under this Agreement, if the amount so estimated is less than the
Minimum Working Capital, the cash payment to the Holders for the transfer of the
Shares at the Closing shall be reduced by the amount of such shortfall.

        Within thirty (30) days following the Closing, the Holders and the
Company shall determine the actual working capital as of the Closing Date (the
"Closing Working Capital") and promptly notify Buyer of such amount. If the
Closing Working Capital is less than the lower of the Minimum Working Capital or
the estimated working capital as described in the preceding paragraph, as such
would have resulted in a reduced cash payment to the Holders for the Shares at
the Closing (such shortfall being the "Adjustment Amount"), the Holders shall
pay to Buyer the Adjustment Amount in cash.

        (b) Disputed Adjustment Amount. If Buyer shall disagree with the amount
determined to be the Closing Working Capital, it shall notify the Holders in
writing of such disagreement within fifteen (15) business days of its receipt of
the determination of Closing Working Capital. Buyer and the Holders shall use
their best efforts for a period of thirty (30) days following the notice of
disagreement to resolve any disagreement. If at the end of such period, Buyer
and the Holders are unable to resolve the disagreement, KPMG Peat Marwick LLP
(the "Arbitrator") shall be retained to make a final and binding determination
of the actual Closing Working Capital. The determination of the Arbitrator shall
be final, binding and conclusive on the parties. The fees and expenses of the
Arbitrator shall be borne equally by Buyer and the Holders.

        1.7 Additional Consideration.

               (a) Revenue Earn-Out. As additional consideration, Buyer shall
pay to the Holders an amount not to exceed $833,333 and 53,333 Buyer Class A
Units, calculated as set forth in the Earn-Out Schedule (such amount is referred
to herein as the "Additional Consideration") and subject to the terms set forth
in this Section 1.7; provided, however, that no Additional Consideration shall
be paid unless (a) the Company's earnings before interest, taxes and
depreciation ("EBITDA"), determined in accordance with generally accepted
accounting principles ("GAAP"), as a percentage of revenue is at least 14.8% for
the Earn-Out Period (as hereinafter defined) and (b) the Company's Qualified
Revenue (as hereinafter defined) for the Earn-Out Period is equal to or greater
than the amount that is 128.0% of the Company's 1997 Qualified Revenue. For
purposes of this Section 1.7, the term "Earn Out Period" shall mean the twelve
month period ended March 31, 1999 and the term "Qualified Revenue" shall mean
all revenue earned by the Company (including, without limitation, all payments,
reimbursements, fees or penalties received by the Company after March 31, 1998,
whether or not deemed to be earned by the Company prior to such date, in
connection with the termination, winding down of the system or final settling of
accounts of that certain Consulting & Systems Management Agreement between the
Company and Nelson Information, Inc. (the "Nelson Agreement"), or that are
intended to pay the company for services performed under such agreement at rates
higher than the earlier invoiced rates of $80.00 per hour, excluding amounts
billed for services through March 31, 1998, and reimbursable expenses incurred
prior to March 31, 1998), less the Company's actual cost of any resold third
party hardware and/or resold third party software. For purposes of this Section
1.7, EBITDA shall not take into account any payments by the Company of any
payroll taxes and similar charges paid by the Company relating to the
compensation deemed to be received by Charles Blackburn or the Excluded
Optionholders as a result of cancellation of outstanding options to purchase
Common Stock of the Company.

               (b) Earn-Out Statement. Not later than ten (10) days following
the completion of the financial statements of Buyer and the Company for the
period ended March 31, 1999, Buyer shall prepare and deliver to the Holders a
statement setting forth the EBITDA margin of the Company for the Earn-Out
Period, the Qualified Revenue of the Company for the Earn-Out Period, the
percentage growth in Qualified Revenue from 1997 to the end of the Earn-Out
Period and the amount of the Additional Consideration, if any, payable to the
Holders (the "Earn-Out Statement"). The amount of the Additional Consideration
reflected on the Earn-Out Statement shall be paid by Buyer not later than the
thirtieth (30th) business day following the date the Earn-Out Statement is
required to be delivered to the Holders. Notwithstanding the foregoing, the
amount of Additional Consideration, if any, shall be paid to the individuals
listed on Exhibit D (or their heirs or





<PAGE>   9

estates) not later than July 31, 1999. Any objections made to the calculation of
Additional Consideration shall be resolved in accordance with Section 1.7(d).

               (c) Form of Additional Consideration. The Additional
Consideration described on the Earn-Out Schedule shall be paid to the Holders in
accordance with their percentage interests set forth on Exhibit D and in the
form of cash until a total of $833,333 has been paid to such individuals as set
forth on Exhibit D. If the Additional Consideration shall exceed $833,333, Buyer
shall pay such additional amount to the Holders in accordance with their
percentage interests and in the form of Buyer Class A Units to the extent of
53,333 units as set forth on Exhibit D.

          Except as set forth in this Section 1, no additional consideration
will be paid to the Holders pursuant to this Agreement.

               (d) Disputed Additional Consideration. If the Holders shall
disagree with the amount determined to be the Additional Consideration, the 1998
Qualified Revenue or the EBITDA determination in Section 1.7, it shall notify
Buyer in writing of such disagreement within ten (10) business days of its
receipt of the Earn-Out Statement. Buyer shall pay any undisputed Additional
Consideration in accordance with Section 1.7(b). The parties acknowledge that

regulation or order as they relate to the Employee Programs.

and effect.

               (k) There is no contract, agreement, plan or arrangement covering
any employee or former employee of the Company or any Affiliate (with respect to

          to, any multiple employer welfare arrangement (within the meaning of
          ERISA Section 3(4)), plan to which more than one unaffiliated employer
          contributes and any employee benefit plan (such as a foreign or excess

          Employee Program shall include a reference to such trust.

                    (ii) An entity "maintains" an Employee Program if such
          entity sponsors, contributes to, or provides (or has promised to

          (by agreement or under applicable law) to contribute to or provide
          benefits under such Employee Program, or if such Employee Program
          provides benefits to or otherwise covers employees of such entity, or
          their spouses, dependents, or beneficiaries.

                    (iii) An entity is an "Affiliate" of the Company if it would
          have ever been considered a single employer with the Company under
          ERISA Section 4001(b) or part of the same "controlled group" as the
          Company or any of its Subsidiaries for purposes of ERISA Section

instrument to be executed and delivered by or on behalf of such Holder pursuant
to this Agreement and to carry out the transactions contemplated hereby and

delivered by such Holder pursuant to this Agreement constitutes a valid and
binding obligation of such Holder, enforceable in accordance with their
respective terms, subject to the effect of any applicable bankruptcy,
reorganization, insolvency, moratorium or similar laws affecting creditors'

including, without limitation, the possible unavailability of specific
performance or injunctive relief, regardless of whether considered in a
proceeding in equity or at law, and such Holder has full power and authority to
transfer, sell and deliver the Shares to Buyer pursuant to this Agreement. The
execution, delivery and performance of this Agreement and each such agreement,
document and instrument:

                    (i) does not and will not violate any provision of any laws
          of the United States or any state or other jurisdiction applicable to
          such Holder, or require such Holder to obtain any approval, consent or
          waiver from, or make any filing with, any person or entity
          (governmental or otherwise) that has not been obtained or made; and

                    (ii) does not and will not result in a breach of, constitute
          a default under, accelerate any obligation under, or give rise to a
          right of termination of, any indenture or loan or credit agreement or
          any other material agreement, contract, instrument, mortgage, lien,
          lease, permit, authorization, order, writ, judgment, injunction,

          Company or on Shares owned by such Holder.

          3.3. Finder's Fee. Except as disclosed in Section 2.20, such Holder
has not incurred or become liable for any broker's commission or finder's fee
relating to or in connection with the transactions contemplated by this
Agreement.

          3.4. Agreements. Other than as set forth on Schedule 3.4 and except
for agreements unrelated to the business of the Company (so long as any such
agreements could not be deemed to have an adverse effect on the Company), each
such Holder is not a party to any non-competition, trade secret or
confidentiality agreement with any party other than the




<PAGE>   33

Company, other than any such agreement that may be entered into in connection
with such Holder's employment by the Company. There are no agreements or
arrangements not contained herein or disclosed in a Schedule hereto, to which
such Holder is a party relating to the business of the Company or to such
Holder's rights and obligations as a shareholder, director or officer of the
Company. Except as set forth on Schedule 3.4, such Holder does not own, directly

Company, or any organization which has a contract or arrangement with the
Company.

          3.5. Experience; Accredited Investor. Each Holder has substantial
experience in evaluating and investing in private placement transactions of
securities in companies similar to the Buyer so that he is capable of evaluating
the merits and risks of acquiring the Buyer Class A Units as partial
consideration for sale of the Shares and has the capacity to protect his own
interests. Each Holder must bear the economic risk of holding the Buyer Class A
Units indefinitely unless such securities are registered pursuant to the
Securities Act, or an exemption from registration is available for the
disposition thereof. Each Holder understands that there is no assurance that any
exemption from registration under the Securities Act will be available. Except
as set forth on Schedule 3.5, each Holder is an "accredited investor" as defined
in Rule 501 under the Securities Act.

          3.6. Investment. Such Holder is acquiring the Buyer Class A Units for
such Holder's own account for investment only, and not with the view to, or for
resale in connection with, any distribution thereof. It understands that the
Buyer Class A Units acquired have not been, and will not be, registered under
the Securities Act by reason of a specific exemption from the registration
provisions of the Securities Act, the availability of which depends upon, among
other things, the bona fide nature of the investment intent and the accuracy of
the Holder's representations as express herein.

          3.7. No Public Market. Such Holder understands that no public market
now exists for any of the securities issued by Buyer has not made any assurances
that a public market will ever exist for such securities.

acquiring the Buyer Class A Units, which questions were answered to such
Holder's satisfaction.

decision was made is located at the address of the Holder set forth on the

with and make available to the other parties, during normal business hours, all
books and records, information and employees (without substantial disruption of
employment) which are necessary or useful in connection with any tax inquiry,
audit, investigation or dispute, any litigation or investigation or any other
matter requiring any such books and records, information or employees for any
reasonable business purpose. The party requesting any such books and records,
information or employees shall bear all of the out-of-pocket costs and expenses
(including, without limitation, reasonable attorneys' fees, but excluding
reimbursement for salaries and employee benefits) reasonably incurred in
connection with providing such books and records, information or employees. All
information received pursuant to this Section 6.4(a) shall be subject to the
terms of the Confidentiality Agreement.

               (b) Cooperation and Records Retention. The Holders and Buyer
shall (i) each provide the other with such assistance as may reasonably be
requested in connection with the preparation of any return, audit, or other
examination by any taxing authority or judicial or administrative proceedings
relating to liability for Taxes, (ii) each retain and provide the others with
any records or other information that may be relevant to such return, audit or
examination, proceeding or determination, and (iii) each provide the others with
any final determination of any such audit or examination, proceeding, or
determination that affects any amount required to be shown on any tax return of
the others for any period. Without limiting the generality of the foregoing, the
Holders and Buyer shall each retain, until the applicable statutes of
limitations (including any extensions) have expired, copies of all tax returns,
supporting work schedules, and other records or information that may be relevant
to such returns for all tax periods or portions thereof ending on or before the
Closing Date and shall not destroy or otherwise dispose of any such records
without first providing the other parties with a reasonable opportunity to
review and copy the same.

          6.4. Release of Personal Guarantees. Buyer agrees to use its
commercially reasonable efforts to have Messrs. Bhaskaran and Shepherd released
from those guarantees listed on Schedule 6.4 hereto (the "Guarantees"),
including the offer by Buyer to substitute Buyer for Messrs. Bhaskaran and
Shepherd on each such guaranty. To the extent that Buyer has not obtained all
such releases on or prior to the Closing, then Buyer shall indemnify and hold
harmless Messrs. Bhaskaran and Shepherd for any losses, costs, claims and
liabilities and expenses (including reasonable attorney's fees) resulting from
any of the obligations of Messrs. Bhaskaran and Shepherd under the Guarantees.

          6.5. Right of First Offer on Dispositions of Holders.



<PAGE>   43

               (a) Termination of Employment for other than Cause.
Notwithstanding Section 6.4 of the Buyer Operating Agreement, in the event a
Holder's employment with the Company is terminated by the Company for other than
Cause (as hereinafter defined), Buyer shall not have the right to repurchase the
Buyer Class A Units issued to such Holder in connection with this Agreement as
provided by Section 6.4 of the Buyer Operating Agreement; provided, however,
that Buyer shall have the right of first offer to purchase any such Buyer Class
A Units which such Holder, from time to time, proposes to sell or transfer as
set forth in Section 6.5(c) below (the "Right of First Offer"). Each Holder
acknowledges that in the event such Holder terminates such Holder's employment
with the Company, Buyer shall have the right, but not the obligation, to
repurchase such Holder's Buyer Class A Units as set forth in Section 6.4 of the
Buyer Operating Agreement. For purposes of this Section 6.5, Cause shall have
the meaning ascribed to such term in the Holder's written employment agreement
with the Company, if any. If the Holder has not entered into a written
employment agreement with the Company, Cause shall have the meaning ascribed to
such term in Buyer's form of Employee Equity Participation Agreement (which
definition is set forth on Schedule 6.5 hereto).

               (b) Sale by Ramesh Vasudevan, Padmini Vasudevan and Glenn Van
Straatum. Notwithstanding the foregoing and Section 6.4 of the Buyer Operating
Agreement, Buyer shall not have the right to repurchase the Buyer Class A Units
issued to Ramesh Vasudevan, Padmini Vasudevan and Glenn Van Straatum in
connection with this Agreement as provided by Section 6.4 of the Buyer Operating
Agreement, provided, however, that Buyer shall have the Right of First Offer to
purchase any such Buyer Class A Units which Ramesh Vasudevan, Padmini Vasudevan
and Glenn Van Straatum, from time to time, propose to sell or transfer as set
forth in Section 6.5(c) below.

               (c) Right of First Offer. If at any time the Holder wishes to
sell, assign, transfer or otherwise dispose of any or all of the Buyer Class A
Units owned by him, the Holder shall give a written notice (the "Transfer
Notice") to Buyer, describing fully the proposed transfer, including the number
of the Buyer Class A Units proposed to be transferred, the proposed transfer
price, other terms and conditions, if any, and the name and address of the
proposed transferee (the "Proposed Transferee"). The Transfer Notice shall be
signed both by the Holder and the Proposed Transferee and must constitute a
binding commitment of both such parties for the transfer of such Buyer Class A
Units. Buyer shall have the right to purchase the Buyer Class A Units subject to
the Transfer Notice at a price per share equal to the proposed per unit transfer
price and upon such other terms and conditions as are stated in the Transfer
Notice, by delivery of a notice of exercise of Buyer's Right of First Offer
within thirty (30) days after the date the Transfer Notice

assignable, in whole or in part.

<PAGE>   47



          any and all commitments, indebtedness, suits, demands, obligations and
          liabilities of every kind and nature, including claims and causes of

which such Holder and/or his heirs, executors, administrators, successors or

and such Holder hereby represents that he has not relied upon any
representations, warranties or agreements of any person other than those set
forth in this Agreement.

        Such Holder acknowledges and agrees that the provisions hereof are
reasonable in context and scope, are a material condition to the Company's
willingness to enter into and effect this Agreement and effect the transactions
contemplated hereby and are intended to be and shall be enforced to the full
extent set forth herein.

SECTION 9. INDEMNIFICATION.

          9.1. Indemnification by the Holders. The Holders jointly and severally
agree subsequent to the Closing to indemnify and hold the Company, Buyer and
their respective subsidiaries and affiliates and persons serving as officers,
directors, partners, managers, stockholders, members, employees and agents
thereof (other than the Holders, except to the extent of liabilities incurred in
their capacities as such an officer, director or employee after the Closing)
(individually a "Buyer Indemnified Party" and collectively the "Buyer
Indemnified Parties") harmless from and against any damages, liabilities,
losses, taxes, fines, penalties, costs, and expenses (including, without
limitation, reasonable fees of counsel) of any kind or nature whatsoever
(whether or not arising out of third-party claims and including all amounts paid
in investigation, defense or settlement of the foregoing) which may be sustained
or suffered by any of them arising out of or based upon any of the following
matters:

               (a) fraud, intentional misrepresentation or the cause or
knowledge of a deliberate or willful breach of any representations, warranties
or covenants of the Company or the Holders under this Agreement or in any
certificate, schedule or exhibit delivered pursuant hereto (collectively, "Fraud
Claims");

               (b) any breach of any representation or warranty of the Holders
set forth in Section 2.3 of this Agreement (collectively, "Ownership Claims");

               (c) any liability of the Company or the Holders for Taxes arising
from the activities of the Company and all events and transactions on or prior
to the Closing and any breach of the representations and warranties set forth in
Section 2.8 hereof and any covenant with respect to Taxes or tax related matters
(collectively, "Tax Claims"); and


<PAGE>   49

               (d) other than Fraud Claims, Ownership Claims or Tax Claims, any
other breach of any representation, warranty or covenant of the Holders under
this Agreement or in any schedule or exhibit delivered pursuant hereto, or by
reason of any claim, action or proceeding asserted or instituted growing out of
any matter or thing constituting a breach of such representations, warranties or
covenants (collectively, "General Claims").

        In addition, each Holder severally, but not jointly, agrees subsequent
to the Closing to indemnify and hold all Buyer Indemnified Parties harmless from
and against any damages, liabilities, losses, taxes, fines, penalties, costs,
and expenses (including, without limitation, reasonable fees of counsel) of any
kind or nature whatsoever (whether or not arising out of third-party claims and
including all amounts paid in investigation, defense or settlement of the
foregoing) which may be sustained or suffered by any of them arising out of or
based upon fraud, intentional misrepresentation or any breach (whether or not
deliberate or willful) of any representation or warranty of such Holder
contained in Section 3, or by reason of any claim, action or proceeding asserted
or instituted growing out of any matter or thing constituting a breach of such
representation or warranty (collectively, "Individual Claims").

          9.2. Limitations on Indemnification by the Holders. Anything contained
in this Agreement to the contrary notwithstanding, the liability of the Holders
to provide any indemnification to any Buyer Indemnified Party and right of Buyer
Indemnified Parties to indemnification under Section 9.1 shall be subject to the
following provisions: 

               (a) Other than any claim for breach of any representation or
warranty of the Company or the Holders set forth in Section 2.24 of this
Agreement, no claims for indemnification shall be made under this Agreement
against any Holder, and no indemnification shall be payable to any Buyer
Indemnified Party, with respect to General Claims after the date which is
eighteen (18) months following the Closing.

               (b) The amount to be payable by a Holder to all Buyer Indemnified
Parties for claims for indemnification hereunder shall in no event exceed such
Holder's pro rata share of the total amount to be paid to all Buyer Indemnified
Parties for claims for indemnification hereunder. The pro rata shares of the
Holders for this purpose shall be the same percentages as the Holders'
respective interests in the Additional Consideration as set forth on Exhibit D.

               (c) The aggregate amount to be payable to all Buyer Indemnified
Parties by each Holder for claims for indemnification with respect to General
Claims shall in no event exceed such Holder's pro rata portion of $4,583,333 and
293,333 Buyer Class A Units and one half of the amount determined to be the
Additional Consideration pursuant to Section 1.7.



<PAGE>   50

               (d) In the event that any claim for indemnification arises from a
breach of representation, warranty or covenant which was made or undertaken by a
Holder, by the express terms of this Agreement severally and not jointly, the
Holders shall be severally, but not jointly, liable for indemnification in
respect of such a claim.

               (e) The Holders shall have no obligation for indemnification with
respect to General Claims hereunder until aggregate claims for indemnification
with respect to General Claims hereunder exceed $50,000, in which case the
Holders shall be obligated for indemnification of all General Claims including
the initial $50,000 of such claims.

               (f) Claims for indemnification with respect to Fraud Claims,
Ownership Claims, Individual Claims, or Tax Claims made under this Agreement by
any Buyer Indemnified Party shall not be subject to any of the limitations set
forth in this Section 9.2.

          9.3. Indemnification by Buyer. Buyer agrees to indemnify and hold the
Holders (individually a "Holder Indemnified Party" and collectively the "Holder
Indemnified Parties") harmless from and against any damages, liabilities, losses
and expenses (including, without limitation, reasonable fees of counsel) of any
kind or nature whatsoever (whether or not arising out of third-party claims and
including all amounts paid in investigation, defense or settlement of the
foregoing) which may be sustained or suffered by any of them arising out of or
based upon any breach of any representation, warranty or covenant made by Buyer
in this Agreement or in any certificate delivered by Buyer hereunder, or by
reason of any claim, action or proceeding asserted or instituted growing out of
any matter or thing constituting such a breach.

          9.4. Limitation on Indemnification by Buyer. Notwithstanding the
foregoing, (a) no indemnification shall be payable to the Holders with respect
to claims asserted pursuant to Section 9.3 above after the date which is
eighteen (18) months after the Closing, and the aggregate amount to be payable
to Holders pursuant to Section 9.3 shall not exceed $4,583,333 and 293,333 Buyer
Class A Units and one half of the amount determined to be the Additional
Consideration pursuant to Section 1.7 and (b) Buyer shall have no obligation for
indemnification hereunder until aggregate claims for indemnification hereunder
exceed $50,000, in which case Buyer shall be obligated for indemnification of
all claims, including the initial $50,000 of such claims; provided, however,
that the limitations set forth herein shall not apply to a claim for
indemnification based upon a breach of Section 5.2 or 5.3 or covenants to be
performed post-Closing. Claims for indemnification with respect to fraud,
intentional misrepresentation or the cause or knowledge of a deliberate or
willful breach of any representations, warranties or covenants of Buyer under
this Agreement or in any certificate, schedule or exhibit delivered pursuant
hereto made under this Agreement by any Holder Indemnified Party shall not be
subject to any of the limitations set forth in this Section 9.4.


<PAGE>   51

          9.5. Notice; Defense of Claims. An indemnified party shall make claims
for indemnification hereunder by giving written notice thereof to the
indemnifying party within the period in which indemnification claims can be made
hereunder. If indemnification is sought for a claim or liability asserted by a
third party, the indemnified party shall also give written notice thereof to the
indemnifying party promptly after it receives notice of the claim or liability
being asserted, but the failure to do so shall not relieve the indemnifying
party from any liability except to the extent that it is prejudiced by the
failure or delay in giving such notice. Such notice shall summarize the bases
for the claim for indemnification and any claim or liability being asserted by a
third party. Within 20 days after receiving such notice the indemnifying party
shall give written notice to the indemnified party stating whether it disputes
the claim for indemnification and whether it will defend against any third party
claim or liability at its own cost and expense. If the indemnifying party fails
to give notice that it disputes an indemnification claim within 20 days after
receipt of notice thereof, it shall be deemed to have accepted and agreed to the
claim, which shall become immediately due and payable. The indemnifying party
shall be entitled to direct the defense against a third party claim or liability
with counsel selected by it (subject to the consent of the indemnified party,
which consent shall not be unreasonably withheld) as long as the indemnifying
party is conducting a good faith and diligent defense. The indemnified party
shall at all times have the right to fully participate in the defense of a third
party claim or liability at its own expense directly or through counsel;
provided, however, that if the named parties to the action or proceeding include
both the indemnifying party and the indemnified party and the indemnified party
is advised that representation of both parties by the same counsel would be
inappropriate under applicable standards of professional conduct, the
indemnified party may engage separate counsel at the expense of the indemnifying
party. If no such notice of intent to dispute and defend a third party claim or
liability is given by the indemnifying party, or if such good faith and diligent
defense is not being or ceases to be conducted by the indemnifying party, the
indemnified party shall have the right, at the expense of the indemnifying
party, to undertake the defense of such claim or liability (with counsel
selected by the indemnified party), and to compromise or settle it, exercising
reasonable business judgment. If the third party claim or liability is one that
by its nature cannot be defended solely by the indemnifying party, then the
indemnified party shall make available such information and assistance as the
indemnifying party may reasonably request and shall cooperate with the
indemnifying party in such defense, at the expense of the indemnifying party.

          9.6. Satisfaction of Holder Indemnification Obligations. In order to
satisfy the indemnification obligations of the Holders hereunder, a Buyer
Indemnified Party shall proceed first directly against the Escrow Deposit as
further set forth in the Escrow Agreement and then directly against the Holders,
subject to the limitations set forth in Section 9.2, as applicable. As further
set forth in the Escrow Agreement, all claims against the Escrow Deposit shall
be satisfied first against the cash portion thereof and then against the Buyer
Class A Units.



<PAGE>   52
          9.7. Valuation of Buyer Class A Units. Except as provided in the
Escrow Agreement, the Holders may, at their option, elect to satisfy any
indemnification claims under this Agreement by delivering Buyer Class A Units to
the Buyer Indemnified Parties up to a maximum of 293,333 Buyer Class A Units. To
the extent that Buyer Class A Units are used to satisfy indemnification claims
under this Agreement, such units shall be valued in accordance with the terms of
the Escrow Agreement.

SECTION 10. MISCELLANEOUS.

          10.1. Recapitalization of Buyer and Holdings. The Company and each of
the Holders hereby agree and acknowledge that they have been informed that Buyer
and Holdings have adopted a recapitalization plan (the "Recapitalization") which
has not yet been effectuated. It is the intention of Buyer, Holdings, and their
members to effectuate the Recapitalization as soon as practicable following the
Closing. The Company and each of the Holders hereby consents and agrees to each
and every element of the Recapitalization which is set forth on Schedule 10.1
attached hereto; the results of the Recapitalization are shown on Exhibit I
attached hereto in the form of a structure chart. Buyer and each Holder agree
and acknowledge that the terms of the Recapitalization as set forth on Schedule
10.1 and illustrated in Exhibit I do not incorporate or reflect the fact that
there are employee equity participation rights (" Buyer SARs") in Buyer which
may be converted into Class A Common Units of Buyer. There are currently 944,000
Buyer SARs outstanding with an equivalent strike price of $5.00 per unit and
927,010 Buyer SARs outstanding with an equivalent strike price of $7.50 per unit
and additional Buyer SARs may be issued. Additional Class A Common Units of
Buyer may be issued in future acquisitions. In addition, the terms of the
Recapitalization as set forth on Schedule 10.1 and illustrated on Exhibit I have
been prepared on the assumption that both this transaction and the so-called
"PTG" transaction will be consummated; in the event that the "PTG" transaction
does not close either prior to or after the Recapitalization, then the terms of
the Recapitalization will be adjusted accordingly. The Company and each Holder
further agree and acknowledge that no further consents need be obtained from
them to effectuate the Recapitalization after the Closing Date and that they
agree and consent to the necessary steps that will be taken and to the
documentation that will be prepared and executed to complete the
Recapitalization.

          10.2. Fees and Expenses. The Company will pay the reasonable fees and
out-of-pocket expenses of Pillsbury Madison & Sutro LLP for services as counsel
to the Company and the Holders in connection with the transactions contemplated
herein up to a maximum of $60,000 after submission of a reasonably detailed
invoice. At the Closing and for administrative convenience, Nextera will make a
payment by wire transfer on behalf of the Holders of $250,000 from the proceeds
otherwise due the Holders in full satisfaction of the investment banking fees of
Alliant Partners with respect to this transaction. The Holders shall bear all
other fees,





<PAGE>   53

commissions and expenses of the Company and the Holders incurred in connection
with the negotiation and the consummation of the transactions contemplated by
this Agreement.

          10.3. Governing Law. This Agreement shall be construed under and
governed by the internal laws of the Commonwealth of Massachusetts without

Any notice given hereunder may be given on behalf of any party by his counsel or
other authorized representatives.

          10.5. Entire Agreement. This Agreement, including the Schedules and
Exhibits hereto, reflects the entire agreement of the parties with respect to
its subject matter, and supersedes all previous written or oral negotiations,
commitments and writings. No promises, representations, understandings,
warranties and agreements have been made by any of the parties hereto except as
referred to herein or in such Schedules and Exhibits; and all inducements to the
making of this Agreement relied upon by either party hereto have been expressed
herein or in such Schedules or Exhibits.

          10.6. Assignability; Binding Effect. This Agreement (including any
obligation of Buyer to pay Additional Consideration to the Holders) shall only
be assignable by Buyer to a corporation or partnership controlling, controlled
by or under common control with Buyer upon written notice to the Company and the
Holders. This Agreement may not be assigned by any Holder or the Company without
the prior written consent of Buyer. This Agreement shall be binding upon and
enforceable by, and shall inure to the benefit of, the parties hereto and their
respective successors and permitted assigns.

          10.7. Captions and Gender. The captions in this Agreement are for
convenience only and shall not affect the construction or interpretation of any
term or provision hereof. The use in this Agreement of the masculine pronoun in
reference to a party hereto shall be deemed to include the feminine or neuter,
as the context may require.

          10.8. Execution in Counterparts. For the convenience of the parties
and to facilitate execution, this Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which shall

          10.9. Amendments. This Agreement may not be amended or modified, nor
may compliance with any condition or covenant set forth herein be waived, except
by a writing duly and validly executed by each party hereto, or in the case of a
waiver, the party waiving compliance.

          10.10. Publicity and Disclosures. No press releases or public
disclosure, either written or oral, of the transactions contemplated by this
Agreement, shall be made by a party to this Agreement without the prior
knowledge and written consent of Buyer and the Company.

          10.11. Specific Performance. The parties agree that it would be
difficult to measure damages which might result from a breach of this Agreement
by the Company or the Holders and that money damages would be an inadequate
remedy for such a breach. Accordingly, if there is a breach or proposed breach
of any provision of this Agreement by the Company or the Holders, and Buyer does
not elect to terminate under Section 8, Buyer shall be entitled, in addition to
any other remedies which it may have, to an injunction or other appropriate
equitable relief to restrain such breach without having to show or prove actual
damage to Buyer.

                                ESCROW AGREEMENT

matters as specified in Section 9 of the Purchase Agreement; and

                  WHEREAS, to secure payment of the Holders' indemnification

Representative and Buyer, the Escrow Agent shall not invest all or any portion

together with the underlying portion of the original Escrow Deposit pursuant to
the terms of this Agreement. The parties agree that to the extent permitted by
applicable law, including Section 468B(g) of the Internal Revenue Code of 1986,
as amended, the Holders will include all amounts earned on the Escrow Deposit in
accordance with their respective percentage interests in their gross income for
federal, state and local income tax (collectively, "income tax") purposes and
pay any income tax resulting therefrom.

                  3. Claims Against Escrow Deposit.

                  (a) At any time or times prior to the expiration of this
Agreement, Buyer may make claims against the Escrow Deposit for indemnification
pursuant to and in accordance with Article XII of the Purchase Agreement . Buyer
shall notify the Escrow Representative and the Escrow Agent in writing prior to
the expiration of this Agreement of each such claim, including a summary of the
amount of and bases for such claim. If the Escrow Representative shall dispute
such claim, the Escrow Representative shall give written notice thereof to Buyer
and to the Escrow Agent within thirty (30) days after receipt of notice of
Buyer's claim, in which case the Escrow Agent shall continue to hold the Escrow
Deposit in accordance with the terms of this Agreement; otherwise, such claim
shall be deemed to have been acknowledged to be payable out of the Escrow
Deposit in the full amount thereof and the Escrow Agent shall use its best
efforts to pay such claim to Holdings within three (3) business days after
expiration of said thirty day period or as soon thereafter as possible. If the
amount of the claim exceeds the value of the Escrow Deposit, the Escrow Agent
shall have no liability or responsibility for any deficiency.

                  (b) The Escrow Agent shall follow the procedure below in
making any payment in satisfaction of a claim against the Escrow Deposit:

                           (i) The Escrow Agent shall make such payment first
from the Escrowed Cash and any cash additions to or earnings on the Escrow
Deposit until all cash in the Escrow Deposit has been exhausted.

                           (ii) To the extent that any claim exceeds the amount
of Escrowed Cash or other cash in the Escrow Deposit, the Escrow Agent shall
make payment from the Escrowed Units in such number of Escrowed Units (computed
to the nearest whole unit) having a value equal to the value of the claim not
satisfied by cash payment. Any payment of Escrowed Units by the Escrow Agent to
Holdings shall be treated as a sale by the Holders of such Escrowed Units for
the value described herein. The value of an Escrowed Unit for purposes of this
Section shall be the fair market value of such unit on the date of the claim as
determined by the Board of Directors of Buyer (the "Board"). The fair market
value shall be determined in good faith by the Board and the Board shall notify
the Escrow Representative and Escrow Agent in writing of its determination (the
"Valuation Notice"). If the Escrow Representative disputes the fair market value
of the Escrowed Units as determined by the Board, then the Escrow Representative
shall so notify the Board and Escrow Agent in writing (the "Appraisal Notice")
within five (5) business days of receipt of the Valuation Notice. Within fifteen
(15) business days of the receipt of the Appraisal Notice, the Board and the
Escrow Representative shall each appoint a professional appraiser to determine
the fair market value of the Escrowed Units. Each appraiser shall have at least
five (5) years experience in appraising companies similar to Buyer. The two
appraisers shall within the succeeding twenty (20) day period after their
selection, attempt to reach agreement on the fair market value. If the
appraisers reach such agreement they shall so notify the Escrow Agent and their
agreement shall be final and binding on Buyer, Holdings, the Board, the Escrow
Representative, the Company, the Holders, and their affiliates. If the
appraisers fail to agree, they shall within ten (10) days thereafter select a
third appraiser with the same qualification requirements, and the three (3)
appraisers shall establish the fair market value by majority vote within the
succeeding twenty (20) day period and shall notify the Escrow Agent of their



                                       3

determination. Such determination of the fair market value shall be final and
binding on Buyer, Holdings, the Board, the Escrow Representative, the Holders,
the Company, and their affiliates. In all events, the appraisers selected shall
be unaffiliated with and otherwise independent of Buyer, Holdings, the Board,
the Company, the Escrow Representative, the Company, the Holders, and their
affiliates. If the fair market value of the Escrowed Units, as determined by the
appraisers, is less than or no more than five percent (5%) greater than the
value as determined by the Board, then the Holders shall pay all costs
associated with the appraisers. If the fair market value as determined by the
appraisers is more than five percent (5%) greater than the value as determined
by the Board, then Buyer shall pay for all costs associated with the appraisers.
The Escrowed Units delivered to Holdings in satisfaction of a claim shall be
allocated among the Holders so as to reduce each Holder's interest in the
remaining Escrowed Units by the pro rata interests shown in Exhibit A. In the
event that the Escrow Agent must make payment with a number of units less than
or different from the number of units represented by a certificate in the Escrow
Deposit, the Escrow Agent shall surrender such certificate to Buyer and Buyer
shall issue to the Escrow Agent certificates of Buyer Class A Units identical in
form but for the number of units as necessary to allow for proper payment of the
claim so long as the number of units of the new certificates plus the amount of
units used to satisfy such claim shall be equivalent to the total number of
units covered by the surrendered certificate.

                  4. Disputed Claims.

                  (a) If the Escrow Representative shall dispute an
indemnification claim of Buyer as above provided, the Escrow Agent shall set
aside a portion of the Escrow Deposit sufficient to pay said claim in full (the
"Set Aside Amount"). If Buyer notifies the Escrow Agent in writing that it has
made out-of-pocket expenditures in connection with any such disputed claim, and
provides paid receipts for such expenditures, in addition to expenditures
included in the Set Aside Amount, an amount equal to such additional
expenditures shall be added to the Set Aside Amount. If the Set Aside Amount
exceeds the amount of the Escrowed Cash, the Escrow Agent shall set aside an
appropriate number of Escrowed Units as determined by the procedure described in
Section 3(b)(ii) above.

                  (b) If the disputed indemnification claim has not been
resolved or compromised within sixty (60) days after the Escrow Representative
sends notice of dispute of the same, or in the event of a third-party claim or
suit, within fifteen (15) days after its resolution or compromise, said
indemnification claim shall be referred to the American Arbitration Association,
to be settled by binding arbitration in Boston, Massachusetts, in accordance
with the commercial arbitration rules of the Association. The fees and expenses
of the arbitrator shall be borne equally by the Holders and Buyer. In no event
shall the Escrow Agent be responsible for any fee or expense of any party to any
arbitration proceeding. The determination of the arbitrator as to the amount, if
any, of the indemnification claim which is properly allowable shall be
conclusive and binding upon the parties hereto and judgment may be entered
thereon in any court having jurisdiction thereof, including, without limitation,
any Superior Court in the Commonwealth of Massachusetts. The arbitrator shall
have the authority to award to the prevailing party reasonable costs and
expenses including attorney's fees and the cost of arbitration. The Escrow Agent
shall use its best efforts to make payment of such claim, as and to the extent
allowed, to Buyer out of the Set Aside 

                                       4


<PAGE>   5

Amount (or if insufficient, out of the Escrow Deposit) within three (3) business
days following the Escrow Agent's receipt of said determination or as soon
thereafter as possible.

                  (c) Notwithstanding Section 4(b), if a disputed
indemnification claim has not been resolved or compromised as of the Termination
Date (as hereinafter defined), and such claim does not involve a third-party
claim or suit, Buyer and the Escrow Representative shall continue to negotiate
in good faith a settlement of such claims for a period of ten (10) days. If,
after the expiration of such ten-day period, such indemnification claim still
has not been resolved or compromised, such claim shall be settled in accordance
with the arbitration provisions set forth in Section 4(b).

                  (d) It is understood and agreed that should any dispute arise
under this Section 4, the Escrow Agent, upon receipt of written notice of such
dispute or claim by the Escrow Representative, is authorized and directed to
retain in its possession without liability to anyone, the Set Aside Amount
relating to such dispute plus any expenditures of Buyer made pursuant to Section
4(a) until such dispute shall have been settled pursuant to this Section 4. The
Escrow Agent may, but shall be under no duty whatsoever to, institute or defend
any legal proceedings which relate to the Escrow Deposit.

                  5. Termination. This Agreement shall terminate on the date
that the Escrow Deposit is reduced to zero as the result of payments by the
Escrow Agent to Holdings in accordance with the provisions of Section 3 or
Section 4. If, however, the Escrow Deposit has not been reduced to zero as of
the date that is eighteen (18) months following the date of this Agreement (the
"Termination Date") and there are no outstanding indemnification claims on the
Termination Date, this Agreement shall terminate and the Escrow Agent shall
distribute the amount remaining in the Escrow Deposit to the Holders in
accordance with their pro rata interest in the Escrow Deposit as set forth in
Exhibit A attached hereto; otherwise this Agreement shall continue in effect
until all indemnification claims Buyer has made pursuant to Section 3 hereof on
or prior to the Termination Date shall have been disposed of. As of the
Termination Date, an amount of the Escrow Deposit adequate to cover all disputed
and undisputed claims made by Buyer pursuant to Section 3 hereof, plus an
additional ten percent (10%) of any such amount to cover potential expenses of
Buyer associated with such claims, will be held by the Escrow Agent, and the
Escrow Agent shall distribute on the Termination Date the balance, if any, of
the Escrow Deposit to the Holders in accordance with their pro rata interest in
the Escrow Deposit as set forth in Exhibit A attached hereto. At such time as
all remaining indemnification claims hereunder have been resolved and the Escrow
Agent has received a written notice executed by Buyer and the Escrow
Representative, or notification of a determination of an arbitrator pursuant to
Section 4(b), to that effect and any amounts to be distributed to Holdings in
connection therewith have been so distributed, the Escrow Agent shall distribute
the remaining Escrow Deposit, if any, to the Holders in accordance with their
pro rata interest in the Escrow Deposit as set forth in Exhibit A attached
hereto.

                  6. The Escrow Agent.

                  (a) Direction from Buyer and Escrow Representative.
Notwithstanding anything herein to the contrary, the Escrow Agent shall promptly
dispose of all or any part of the Escrow Deposit as directed by a writing signed
by Buyer and Escrow Representative.

                  (b) Reliance by Escrow Agent; Liability of Escrow Agent.
Except with respect to capitalized terms used herein and defined in the Purchase
Agreement, the Escrow Agent will not be subject to, or be obliged to recognize,
any other agreement between the parties hereto or directions or instructions not
specifically set forth as provided for herein. The Escrow Agent will not make
any payment or disbursement from or out of the Escrow Deposit that is not
expressly authorized pursuant to this Agreement. The Escrow Agent undertakes to
perform only such duties as are expressly set forth herein. The Escrow Agent may
rely and shall be protected in acting or refraining from acting upon any written
notice, instruction or request furnished to it hereunder and believed by it to
be genuine and to have been signed or presented by the proper party or parties.
The Escrow Agent shall be under no duty to inquire into or investigate the
validity, accuracy or content of any such document. The Escrow Agent shall have
no duty to solicit any payment which may be due it hereunder. The Escrow Agent
shall not be liable for any action taken or omitted by it in good faith unless a
court of competent jurisdiction determines that the Escrow Agent's gross
negligence or willful misconduct was the primary cause of any loss to the Buyer,
Holdings, the Company or the Holders. In the administration of the Escrow
Deposit hereunder, the Escrow Agent may execute any of its powers and perform
its duties hereunder directly or through agents or attorneys and may consult
with counsel, accountants and other skilled persons to be selected and retained
by it. The Escrow Agent shall not be liable for anything done, suffered or
omitted in good faith by it in accordance with the advice or opinion of any such
counsel, accountants or other skilled persons. The Buyer and the Holders jointly
and severally hereby agree to indemnify and hold the Escrow Agent and its
directors, officers, agents and employees (collectively, the "Indemnitees")
harmless from and against any and all claims, liabilities, losses, damages,
fines, penalties, and expenses, including out-of-pocket and incidental expenses
and legal fees and expenses ("Losses") that may be imposed on, incurred by, or
asserted against the Indemnitees or any of them for following any instructions
or other directions upon which the Escrow Agent is authorized to rely pursuant
to the terms of this Agreement. In addition to and not in limitation of the
immediately preceding sentence, the Buyer and the Holders also agree to
indemnify and hold the Indemnitees and each of them harmless from and against
any and all Losses that may be imposed on, incurred by, or asserted against the
Indemnitees or any of them in connection with or arising out of Escrow Agent's
performance under this Agreement, provided the Indemnitees have not acted with
gross negligence or engaged in willful misconduct. Anything in this Agreement to
the contrary notwithstanding, in no event shall the Escrow Agent be liable for
special, indirect or consequential loss or damage of any kind whatsoever
(including but not limited to lost profits). The provisions of this Section 6(b)
shall survive the termination of this Agreement and the resignation or removal
of the Escrow Agent for any reason.

                  (c) Fees and Expenses of the Escrow Agent. All fees of the
Escrow Agent for its services hereunder, together with any expenses reasonably
incurred by the Escrow Agent in connection with this Agreement, shall be shared
equally by Buyer on the one hand and the 

                                       6


<PAGE>   7

Holders on the other. The fees to be paid by the Holders shall be deducted from
the Escrow Deposit.

                  (d) Resignation and Removal of Escrow Agent. Successor Escrow
Agent.

                           (i) The Escrow Agent may resign from its duties 
hereunder by giving each of the parties hereto not less than thirty (30) days
prior written notice of the effective date of such resignation (which effective
date shall be at least thirty (30) days after the date such notice is given). In
addition, the Escrow Agent may be removed and replaced on a date designated in a
written instrument signed by Buyer and the Escrow Representative and delivered
to the Escrow Agent. The parties hereto intend that a successor escrow agent
mutually acceptable to the Escrow Representative and Buyer will be appointed to
fulfill the duties of the Escrow Agent hereunder for the remaining term of this
Agreement in the event of the Escrow Agent's resignation or removal. Upon the
effective date of such resignation or removal, the Escrow Agent shall deliver
the property comprising the Escrow Deposit to such successor escrow agent,
together with an accounting of the investments held by it and all transactions
related to this Agreement, including any distributions made and such records
maintained by the Escrow Agent in connection with its duties hereunder and other
information with respect to the Escrow Deposit as such successor may reasonably
request. If on or before the effective date of such resignation or removal, a
successor escrow agent has not been appointed, the Escrow Agent will thereupon
deposit the Escrow Deposit into the registry of a court of competent
jurisdiction.

                                Upon written acknowledgment by a successor 
escrow agent appointed in accordance with this Section 6(d)(i) of its agreement
to serve as escrow agent hereunder and the receipt of the property then
comprising the Escrow Deposit, the Escrow Agent shall be fully released and
relieved of all duties, responsibilities and obligations under this Agreement,
except for those arising under Section 6(b) of this Agreement, and such
successor escrow agent shall for all purposes hereof be the Escrow Agent.

                           (ii) Any corporation, association or other entity
into which the Escrow Agent may be converted or merged, or with which it may be
consolidated, or to which it may sell or otherwise transfer all or substantially
all of its corporate trust business, or any corporation, association or other
entity resulting from any such merger, conversion, consolidation, sale or other
transfer, shall, ipso facto, be and become successor Escrow Agent hereunder,
vested with all of the powers, discretions, immunities, privileges and all other
matters as was its predecessor, without the execution or filing of any
instrument or any further act on the part or any of the parties hereto, anything
herein to the contrary notwithstanding.

                  7. Voting of Escrowed Units. So long as any Escrowed Units are
retained by the Escrow Agent, the Holders shall not be entitled to exercise the
voting power, if any, with respect to that Holder's proportional interest in the
Escrowed Units as set forth in Exhibit A hereto.

                  8. Governing Law. IT IS THE PARTIES' INTENT THAT THIS
AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH 

                                       7

number by signing and returning a Form W-9 (or Form W-8, in the case of non-U.S.

hereto understand that, in the event their tax identification numbers are not

to time, may require withholding of a portion of any interest or other income
earned on the investment of the Escrow Deposit.

                  12. Force Majeure. Neither Buyer, Holdings, the Company, the

Escrow Agreement, unless such waiver is specified in writing, and then only to

Escrow Agreement on one occasion shall not constitute a waiver of the other
terms of this Escrow Agreement, or of such terms and conditions on any other
occasion.

        2.4.    Purchase Price. In consideration of the sale, transfer,
assignment, conveyance and delivery of the Assets by Seller to Buyer and in
reliance upon the representations and warranties of Seller herein contained and
made at the Closing and upon the terms and subject to the satisfaction of all of
the conditions set forth herein, Buyer agrees that at the Closing, it will (i)
pay to Seller the aggregate amount of (A) Five Million Seven Hundred Three
Thousand Five Hundred Dollars ($5,703,500) and (B) 181,900 Class A Common Units
of Nextera issued pursuant to the Nextera Operating Agreement (collectively with
the Escrow Amount as defined below, the "Purchase Price") (the cash payment to
be made by bank cashier's check in Boston Clearing House Funds or by wire
transfer of immediately available funds) and shall assume the Assumed
Liabilities pursuant to this Agreement and (ii) deliver to the Escrow Agent One
Million Six Thousand Five Hundred Dollars ($1,006,500) (the "Escrowed Cash") and
32,100 Class A Common Units of Nextera (the "Escrowed Units" and together with
the Escrowed Cash the "Escrow Amount") pursuant to and in accordance with the
terms of the Escrow Agreement to be executed in substantially the form attached
hereto as Exhibit B. The Purchase Price shall be allocated among the Assets in
the manner required by Section 1060 of the Code and regulations thereunder.
Exhibit C attached hereto sets forth the amount of the Purchase Price allocable
to the various Assets. Buyer and Seller agree to each prepare and file on a
timely basis with the Internal Revenue Service substantially identical initial
and supplemental Internal Revenue Service Forms 8594 "Asset Acquisition

to any Adjustment Amount determined in accordance with Section 2.5 hereof and to
file all relevant Tax Returns in a manner consistent therewith. Seller and the
Shareholders acknowledge that the value of the Nextera Class A Common Units is
$2.50 per unit.

        2.5.    Working Capital.


<PAGE>   16
                        (a)     Working Capital Adjustment. The amount of the
cash payment to be made by Buyer for the Assets at the Closing is premised upon
Seller delivering to Buyer at least Five Hundred Fifty Thousand Dollars
($550,000) of working capital of which Four Hundred Thousand Dollars ($400,000)
shall be cash, determined in accordance with generally accepted accounting
principles, at the Closing, (such amount being the "Minimum Working Capital").
No later than two (2) business days prior to the Closing Date, Seller shall
advise Buyer and Nextera of its estimate of working capital to be delivered at
the Closing. Without limiting other rights that Buyer and Nextera may have under
this Agreement, if the amount so estimated is less than the Minimum Working
Capital, the cash payment to Seller for the Assets at the Closing shall be
reduced by the amount of such shortfall. If the amount so estimated is greater
than the Minimum Working Capital, the cash payment to Seller for the Assets at
the Closing shall be increased by the amount of such surplus.

                        Within thirty (30) days following the Closing, Seller
shall determine the actual working capital as of the Closing Date (the "Closing
Working Capital") and promptly notify Buyer of such amount. If the Closing
Working Capital is less than the estimated working capital as described in the
preceding paragraph, and would have resulted in a reduced cash payment to Seller
for the Assets at the Closing, Seller and the Shareholders shall pay to Buyer
the amount of such shortfall in cash. If the Closing Working Capital is greater
than the estimated working capital as described in the preceding paragraph, and
would have resulted in an increased cash payment to Seller for the Assets at the
Closing, Buyer shall pay to Seller the amount of such surplus in cash.

                        (b)     Disputed Closing Working Capital. If Buyer shall
disagree with the amount determined to be the Closing Working Capital, it shall
notify Seller and the Shareholders in writing of such disagreement within
fifteen (15) business days of its receipt of the determination of Closing
Working Capital. Buyer, Seller and the Shareholders shall use their commercially
reasonable efforts for a period of thirty (30) days following the notice of
disagreement to resolve any disagreement. If at the end of such period, Buyer,
Seller and the Shareholders are unable to resolve the disagreement, a mutually
agreed upon independent public accounting firm (the "Arbitrator") shall be
retained to make a final and binding determination of the actual Closing Working
Capital. The determination of the Arbitrator shall be final, binding and
conclusive on the parties. The fees and expenses of the Arbitrator shall be
borne equally by Buyer and the Shareholders.

        2.6.    Closing Costs; Transfer Taxes and Fees. Seller shall be
responsible for any documentary and transfer taxes and any sales, use or other
taxes imposed by reason of the transfers of Assets provided hereunder and any
deficiency, interest or penalty asserted with respect thereto. Seller shall pay
the fees and costs of recording or filing all applicable conveyancing
instruments described in Section 3.2(a). Seller shall pay all costs of applying
for new Permits and obtaining the transfer of existing Permits which may be
lawfully transferred.

          REPRESENTATIONS AND WARRANTIES OF SELLER AND THE SHAREHOLDERS

                As a material inducement to Buyer, Nextera and Holdings to enter
into this Agreement and consummate the transactions contemplated hereby, Seller
and each of the Shareholders jointly and severally hereby represent and warrant
to Buyer, Nextera and Holdings as follows, which representations and warranties
are, as of the date hereof, and will be, as of the Closing Date, true and
correct:

        4.1.    Organization and Qualification of Seller. Seller is a
corporation duly organized, validly existing and in good standing under the laws
of the Commonwealth of Massachusetts with corporate power and authority to own
or lease its properties and to conduct its business in the manner and in the
places where such properties are owned or leased or such business as currently
conducted or proposed to be conducted. Copies of the Articles of Organization
and Bylaws of Seller, and all amendments thereto, heretofore delivered to Buyer
are accurate and complete as of the date hereof. Seller is not in violation of
any term of the Articles of Organization or Bylaws of Seller. Seller is not
required to be licensed or qualified to conduct its business or own its property
in any other jurisdiction in which failure to be so licensed or qualified would
have a material adverse effect on Seller.

        4.2.    Shares of Seller; Beneficial Ownership. The authorized capital
stock of Seller consists of 200,000 shares of Common Stock, no par value, of
which 126 shares are duly and validly issued, outstanding, fully paid and
non-assessable and of which 199,874 shares are authorized but unissued (after
giving effect to Seller's repurchase of shares from Patrick S. Noonan) . Other
than as set forth on Exhibit A-1, there are no outstanding options, warrants,
rights, commitments, preemptive rights or agreements of any kind for the
issuance or sale of, or outstanding securities convertible into, any additional
shares of capital stock of any class of Seller. None of Seller's capital stock
has been issued in violation of any federal or state law. There are no voting
trusts, voting agreements, proxies or other agreements, instruments or
undertakings with respect to the voting of the Shares to which Seller or any of
the Holders is a party.

        4.3.    No Subsidiaries. Seller has no subsidiaries or investments in
any other corporation or business organization.

        4.4.    Authority. Seller has full right, authority and power to enter
into this Agreement and each agreement, document and instrument to be executed
and delivered by Seller pursuant to this Agreement and to carry out the
transactions contemplated hereby. The execution, delivery and performance by
Seller of this Agreement and each such other agreement, document and instrument
have been duly authorized by all necessary action of Seller and no other action
on the part of Seller or Shareholders is required in connection therewith.


<PAGE>   19
                This Agreement and each agreement, document and instrument
executed and delivered by Seller and each of the Shareholders pursuant to this
Agreement constitutes, or when executed and delivered will constitute, valid and
binding obligations of Seller and each of the Shareholders enforceable in
accordance with their terms, subject to the effect of any applicable bankruptcy,
reorganization, insolvency, moratorium or similar laws affecting creditors'
rights generally and subject to the effect of general principles of equity,
including, without limitation, the possible unavailability of specific
performance or injunctive relief, regardless of whether considered in a
proceeding in equity or at law. The execution, delivery and performance by
Seller of this Agreement and each such agreement, document and instrument:

                                (i)     does not and will not violate any
provision of the Articles of Organization and Bylaws of Seller;

                                (ii)    does not and will not violate any laws
of the United States, or any state or other jurisdiction applicable to Seller or
require Seller to obtain any approval, consent or waiver of, or make any filing
with, any person or entity (governmental or otherwise) that has not been
obtained or made; and

                                (iii)   except as set forth in Schedule 4.4,
does not and will not result in a breach of, constitute a default under,
accelerate any obligation under, or give rise to a right of termination of any
indenture or loan or credit agreement or any other agreement, contract,
instrument, mortgage, lien, lease, permit, authorization, order, writ, judgment,
injunction, decree, determination or arbitration award to which Seller is a
party or by which the property of Seller is bound or affected and which is
material to the Seller, the Assets or the Business, or result in the creation or
imposition of any mortgage, pledge, lien, security interest or other charge or
encumbrance on any of Seller's capital stock.

        4.5.    Assets. Excluding the Leased Real Property, Seller has and will
transfer good and marketable title to the Assets and upon the consummation of
the transactions contemplated hereby, Buyer will acquire good and marketable
title to all of the Assets, free and clear of any Encumbrances other than the
Permitted Liens. The Assets include all assets necessary for the conduct of the
Business as currently conducted and proposed to be conducted. Schedule 4.5
contains accurate lists and summary descriptions of all tangible Assets where
the value of an individual item exceeds $5,000 or where an aggregate of similar
items exceeds $20,000. All tangible assets and properties which are part of the
Assets are in good operating condition and repair (normal wear and tear
excepted)and are usable in the ordinary course of business and conform in all
material respects to all applicable Regulations (including Environmental Laws)
relating to their construction, use and operation.

        4.6.    Real Property.

leased by Seller is identified on Schedule 4.6 (herein referred to as the
"Leased Real Property").

                        (a)     Leases. All leases of Leased Real Property are
identified on Schedule 4.6 (each such lease is herein referred to as a "Facility
Lease"), and true and complete


<PAGE>   20
copies thereof have been delivered to Nextera. Each Facility Lease has been duly
authorized and executed by the parties and is in full force and effect and
binding and enforceable against the parties thereto. Seller is not in default
under any Facility Lease, nor has any event occurred which, with notice or the
passage of time, or both, would give rise to such a default. To Seller's
knowledge, the other party to each Facility Lease is not in default under such
Facility Lease and there is no event which, with notice or the passage of time,
or both, would give rise to such a default.

                        (b)     Leases or Other Agreements. Except for Facility
Leases listed on Schedule 4.6, there are no leases, subleases, licenses,
occupancy agreements, options, rights, concessions or other agreements or
arrangements, written or oral, granting to any person the right to purchase, use
or occupy any real property in connection with the Business or any portion
thereof or interest in any such real property.

                        (c)     Facility Leases and Leased Real Property. With
respect to each Facility Lease, Seller has and will transfer to Buyer at the
Closing an unencumbered interest in the Leasehold Estate subject to the
Permitted Liens. Seller enjoys peaceful and undisturbed possession of all the
Leased Real Property.

                        (d)     Condition of Leased Real Property. To the
knowledge of Seller there are no material defects in the physical condition of
any portion of the Leased Real Property and all such Leased Real Property is in
good operating condition and repair (normal wear and tear excepted), and has
been well maintained.

                        (e)     Compliance with the Law. Seller has not received
any notice from any governmental authority of any violation of any law,
ordinance, regulation, license, permit or authorization issued with respect to
the Leased Real Property that has not been heretofore corrected. Seller has not
received any notice of any real estate tax deficiency or assessment and is not
aware of any proposed deficiency, claim or assessment with respect to any of the
Leased Real Property, or any pending or threatened condemnation thereof.

        4.7.    Financial Statements.

                        (a)     Seller has delivered to Nextera the following

Driscoll, and balance sheets of Seller as of January 31, 1998 and February 28,
1998 and statements of income, retained earnings and cash flows for the interim
periods ended January 31, 1998 and February 28, 1998 (the "Financial
Statements"). The December 31, 1997 balance sheet is hereinafter referred to as
the "Base Balance Sheet" and December 31, 1997 is hereafter referred to as the
"Base Balance Sheet Date." The Financial Statements, have been prepared in
accordance with generally accepted accounting principles applied consistently
during the periods covered thereby, and said Financial Statements, present
fairly in all material respects the financial condition of Seller at the dates
of said statements and the results of its operations for the periods covered
thereby, and the unaudited balance sheet and statements of income, retained
earnings and


<PAGE>   21
cash flows for the interim periods ended January 31, 1998 and February 28, 1998
provided by Seller to Nextera since the date of the Base Balance Sheet present
fairly and completely in all material respects the information purported to be
shown thereon. It is understood that the financial statements and results of the
interim periods do not include notes, may be subject to adjustments and are not
necessarily indicative of results that may be expected for the entire year or
other interim periods.

                        (b)     As of the date of the Base Balance Sheet, Seller
did not have any Liabilities of any nature, whether accrued, absolute or
contingent (including without limitation, Liabilities as guarantor or otherwise

of Seller or the conduct of its business prior to the date of the Base Balance
Sheet), except Liabilities stated or adequately reserved against on the Base
Balance Sheet or reflected in Disclosure Schedule and future performance
obligations under Contracts other than as a result of a default existing as of
the Closing.

                        (c)     Seller's fiscal year 1998 operating budget dated
March 6, 1998 which has previously been supplied by Seller to Nextera has been
prepared in good faith on the basis of assumptions by Seller which Seller
believed were reasonable at the time of the preparation of such projections. It
is recognized and understood, however, without affecting or limiting any other
representation or warranty in this Agreement, that such projections do not
constitute any representation or warranty as to the future performance of the
Business and that some assumptions may not materialize and unanticipated events
and circumstances may occur subsequent to the date of the projections and that
therefore actual results may vary materially from projected results and such
variations may be adverse.

                        (d)     Except as set forth on Schedule 4.7 and for the
Excluded Liabilities, as of the date hereof and as of the Closing, Seller has

otherwise with respect to obligations of others, or Liabilities for taxes due or

had been asserted as of such date), except Liabilities (i) stated or adequately
reserved against on the Base Balance Sheet or the notes thereto, (ii) incurred
or arising in the ordinary course of business under Contracts, Leases, Permits
and other business arrangements described in the Disclosure Schedule (and under

business of Seller consistent with the terms of this Agreement (none of which
relates to any Default under any Contract or Lease, breach of warranty, tort
infringement or violation of any Regulation or Court Order or arose out of any
Action) and none of which, individually or in the aggregate, has or would have a
material adverse effect on the Business or the Assets.

                                (iv)    Distribution, franchise, license,
technical assistance, sales, commission, consulting, agency or advertising
contracts related to the Assets or the Business;

                                (v)     Options with respect to any property,
real or personal, whether Seller shall be the grantor or grantee thereunder;

                                (vi)    Contracts involving future expenditures
or Liabilities, actual or potential, in excess of $25,000 or otherwise material
to the Business or the Assets;

                                (vii)   Contracts or commitments relating to
commission arrangements with others;

                                (viii)  Promissory notes, loans, agreements,
indentures, evidences of indebtedness, letters of credit, guarantees, or other
instruments relating to an obligation to pay money, individually in excess of or
in the aggregate in excess of $25,000, whether Seller shall be the borrower,
lender or guarantor thereunder or whereby any Assets are pledged (excluding
credit provided by Seller in the ordinary course of business to purchasers of
its products);

                                (ix)    Contracts containing covenants limiting
the freedom of Seller or any officer, director, shareholder or affiliate of
Seller, to engage in any line of business or compete with any person;

                                (x)     Any Contract to supply services to the
United States, state or local government or any agency or department thereof;

                                (xi)    Leases of real property;

                                (xii)   Leases of personal property not

                                Seller has delivered to Buyer true, correct and
complete copies of all of the Contracts listed on Schedule 4.9, including all
amendments and supplements thereto. Schedule 4.9 contains a true, correct and
complete (in all material respects) description of Seller's obligations under
all material oral Contracts. Seller represents that none of its "exclusive
focus" agreements (including without limitation Seller's agreements with The
Chubb Corporation, Mead Johnson Nutritionals U.S., and SmithKline Beecham) will
affect the rights of Nextera or any affiliate of Nextera, other than Buyer and
the Shareholders and the former employees of Seller, from engaging in any
business subsequent to the Closing, provided that the foregoing assumes that all
confidential and propriety information of any client subject to an "exclusive
focus" agreement of Seller shall not be disclosed or available to or in any way
used by Nextera or any affiliates of Nextera, other than Buyer, and Buyer will
operate as a separate and distinct business from Nextera's other operations.


<PAGE>   25
                        (b)     Absence of Defaults. Seller has fulfilled, or
taken all action necessary to enable it to fulfill when due, all of its material
obligations under each of such Contracts and Leases. To Seller's knowledge, all
other parties to such Contracts and Leases are currently in compliance in all
material respects with the provisions thereof, no party is in Default thereunder
and no notice of any claim of Default has been given to Seller. Seller has no
reason to believe that the products and services called for by any unfinished
Contract cannot be supplied in accordance with the terms of such Contract,
including time specifications, and has no reason to believe that any unfinished
Contract will upon performance by Seller result in a loss to Seller. With
respect to any Leases, Seller has not received any notice of cancellation or
termination under any option or right reserved to the lessor, or any notice of
Default, thereunder, except for those which have been waived or cured.

                        (c)     Warranty. Seller has committed no act, and there
has been no omission, which may result in, and there has been no occurrence
which may give rise to, Liability for breach of warranty (whether covered by
insurance or not) on the part of Seller, with respect to services rendered prior
to or on the Closing Date.

        4.10.   Permits.

                        (a)     Schedule 4.10 sets forth a complete list of all
Permits used in the operation of the Business or otherwise held by Seller.
Seller has, and at all times has had, all Permits required under any Regulation
(including Environmental Laws) in the operation of its Business or in the
ownership of the Assets (except where the failure to have any Permit has not had
and will not have a material adverse effect on Seller or the Business), and owns
or possesses such Permits free and clear of all Encumbrances other than the
Permitted Liens. Seller is not in Default, nor has it received any notice of any
claim of Default, with respect to any such Permit. Except as otherwise governed
by law, all such Permits are renewable by their terms or in the ordinary course
of business without the need to comply with any special qualification procedures
or to pay any amounts other than routine filing fees and will not be adversely
affected by the completion of the transactions contemplated by this Agreement.
To Seller's knowledge, no present or former Shareholder, director, officer or
employee of Seller or any affiliate thereof, or any other person, firm,
corporation or other entity, owns or has any proprietary, financial or other
interest (direct or indirect) in any Permit which Seller owns, possesses or
uses.

                        (b)     Except as disclosed on Schedule 4.10 hereto, no
notice to, declaration, filing or registration with, or Permit from, any
domestic or foreign governmental or regulatory body or authority, or any other
person or entity, is required to be made or obtained by Seller in connection
with the execution, delivery or performance of this Agreement and the
consummation of the transactions contemplated hereby.

        4.11.   Litigation. Except as set forth on Schedule 4.11, there are no
Actions pending or to the knowledge of Seller, threatened or anticipated (a)
against, related to or affecting (i) Seller, the Business or the Assets
(including with respect to Environmental Laws), (ii) any officers or directors
of Seller as such, or (iii) any Shareholder in such Shareholder's capacity as a
shareholder of Seller, (b) seeking to delay, limit or enjoin the transactions
contemplated by this Agreement (c) that involve the risk of criminal liability
on Seller or any of its officers or directors, or (d) in which


<PAGE>   26
Seller is a plaintiff, including any derivative suits brought by or on behalf of
Seller. Seller is not in Default with respect to or subject to any Court Order,
and there are no unsatisfied judgments against Seller, any Shareholder in such
Shareholder's capacity as a shareholder of Seller, the Business or the Assets.
There is not a reasonable likelihood of an adverse determination of any pending
Actions. There are no Court Orders or agreements with, or liens by, any
governmental authority or quasi-governmental entity relating to any
Environmental Law which regulate, obligate, bind or in any way affect Seller.

        4.12.   Compliance with Law. Except as set forth on Schedule 4.12 Seller
and the conduct of the Business have not violated and are in compliance with all
Regulations and Court Orders relating to the Assets or the Business or
operations of Seller, except where noncompliance would not have a material
adverse effect on the Assets, the Business or Seller. Seller has not received
any notice to the effect that, or otherwise been advised that, it is not in
compliance with any such Regulations or Court Orders, and Seller has no reason
to anticipate that any existing circumstances are likely to result in violations
of any of the foregoing.

        4.13.   Ordinary Course. Except for the transactions contemplated by
this Agreement and as set forth on Schedule 4.13 or the other schedules hereto,
since December 31, 1997, Seller has conducted its business only in the ordinary
course and consistently with its prior practices.

        4.14.   Directors and Officers. Schedule 4.14 hereto contains a true and
complete list of all current members of the Board of Directors and each of the
officers of Seller. In addition, Schedule 4.14 hereto contains a list of all
managers, employees and consultants of Seller who, individually, have received
or are scheduled to receive compensation from Seller for the fiscal years ending
December 31, 1997 and December 31, 1998, in excess of $25,000. In each case such
Schedule includes the current job title and aggregate annual compensation of
each such individual.

        4.15.   Employees; Labor Matters. As of the date of this Agreement
Seller employs a total of approximately nineteen (19) full-time employees.
Except for certain bonuses to be paid to the Shareholders as set forth on
Schedule 4.15(b), Seller is not delinquent in payments to any of its employees
for any wages, salaries, commissions, bonuses or other direct compensation for
any services performed for it to the date hereof or amounts required to be
reimbursed to such employees. Upon termination of the employment of any of said
employees by Seller (assuming Buyer has offered employment to all of said
employees), none of Buyer, Nextera or Holdings will by reason of the
transactions contemplated under this Agreement or anything done prior to the
Closing be liable to any of said employees for so-called "severance pay" or any
other payments. Seller has no policy, practice, plan or program of paying
severance pay or any form of severance compensation in connection with the
termination of employment, except as set forth in Schedule 4.15(c). Seller is in
compliance with all applicable laws and regulations respecting labor,
employment, fair employment practices, work place safety and health, terms and
conditions of employment, and wages and hours. There are no charges of
employment discrimination or unfair labor practices, nor are there any strikes,
slowdowns, stoppages of work, or any other concerted interference with normal
operations which are existing, pending or to Seller's knowledge threatened
against or involving Seller. No question concerning union representation exists
respecting any employees of Seller. There are no grievances, complaints or
charges that have


<PAGE>   27
been filed against Seller under any dispute resolution procedure (including, but
not limited to, any proceedings under any dispute resolution procedure under any
collective bargaining agreement) that might have an adverse effect on Seller or
the conduct of its business, and there is no arbitration or similar proceeding
pending and no claim therefor has been asserted. No collective bargaining
agreement is in effect or is currently being or is about to be negotiated by
Seller. Seller has not received any information indicating that any of its
employment policies or practices is currently being audited or investigated by
any federal, state or local government agency. Seller is, and at all times has
been, in compliance with the requirements of the Immigration Reform Control Act
of 1986.

        4.16.   Banking Relations. All of the arrangements which Seller has with
any banking institution are completely and accurately described in Schedule 4.16
attached hereto, indicating with respect to each of such arrangements the type
of arrangement maintained (such as checking account, borrowing arrangements,
safe deposit box, etc.) and the person or persons authorized in respect thereof.

        4.17.   No Brokers. Neither Seller, the Shareholders nor any of their
respective officers, directors, employees, or affiliates has employed or made
any agreement with any broker, finder or similar agent or any person or firm
which will result in the obligation of Buyer, Nextera, Holdings or any of their
affiliates to pay any finder's fee, brokerage fees or commission or similar
payment in connection with the transactions contemplated hereby.

        4.18.   No Other Agreements to Sell the Assets. Neither Seller, the
Shareholders nor any of their respective officers, directors, employees or
affiliates have any commitment or legal obligation, absolute or contingent, to
any other person or firm other than Buyer to sell, assign, transfer or effect a
sale of any of the Assets (other than inventory or services in the ordinary
course of business), to sell or effect a sale of the capital stock of Seller, to
effect any merger, consolidation, liquidation, dissolution or other
reorganization of Seller, or to enter into any agreement or cause the entering
into of an agreement with respect to any of the foregoing.

        4.19.   Customers, Distributors and Suppliers. Schedule 4.19(a) sets
forth any customer, sales representative or distributor (whether pursuant to a
commission, royalty or other arrangement) which will account for more than
$25,000 in revenue for Seller for the twelve months ending December 31, 1997
(collectively, the "Customers and Distributors"). Schedule 4.19(b) lists all of
the suppliers of Seller to whom during the fiscal year ending December 31, 1997
Seller will make payments aggregating $25,000 or more showing, with respect to
each, the name, address and dollar volume involved (the "Suppliers"). To
Seller's knowledge, the relationships of Seller with its Customers, Distributors
and Suppliers are good commercial working relationships. Except for arrangements
reflected in Seller's financial statements, no Customer, Distributor or Supplier
has canceled, materially modified, or otherwise terminated (other than in
accordance with the terms of a valid contract) its relationship with Seller, or
has during the last twelve months decreased materially its services, supplies or
materials to Seller or its usage or purchase of the services or products of
Seller, nor to the knowledge of Seller, does any Customer, Distributor or
Supplier have any plan or intention to do any of the foregoing, it being
understood that Seller is a management consulting firm and that, at any given 
time, Seller is 


<PAGE>   28
in a different stage of its engagement (i.e., some engagements are increasing
while others are winding down).

        4.20.   Backlog. As of the date hereof, Seller has a backlog of firm
orders for the sale or lease of products or services, for which revenues have
not been recognized by Seller, as set forth in Schedule 4.20.

        4.21.   Proprietary Rights.

                        (a)     Proprietary Rights. Schedule 4.21 lists all of
Seller's Proprietary Rights. The Proprietary Rights listed in the Disclosure
Schedule are all those used by Seller in connection with the Business.

                        (b)     Royalties and Licenses. Except as set forth on
Schedule 4.21 Seller, does not have any obligation to compensate any person for
the use of any such Proprietary Rights nor has Seller granted to any person any
license, option or other rights to use in any manner any of its Proprietary
Rights, whether requiring the payment of royalties or not.

                        (c)     Ownership and Protection of Proprietary Rights.
Except as set forth on Schedule 4.21, Seller owns or has a valid right to use
each of the Proprietary Rights, and the Proprietary Rights will not cease to be
valid rights of Seller by reason of the execution, delivery and performance of
this Agreement or the consummation of the transactions contemplated hereby.
Seller has taken commercially reasonable and prudent steps to protect the
Proprietary Rights from infringement by any other person. Except as set forth on
Schedule 4.21, no other person (i) has notified Seller that it is claiming any
ownership of or right to use such Proprietary Rights, or (ii) to Seller's
knowledge, is infringing upon any such Proprietary Rights in any way. To
Seller's knowledge, except as set forth on Schedule 4.21, Seller's use of the
Proprietary Rights does not and will not conflict with, infringe upon or
otherwise violate the valid rights of any third party in or to such Proprietary
Rights, and no Action has been instituted against or notices received by Seller
that are presently outstanding alleging that Seller's use of the Proprietary
Rights infringes upon or otherwise violates any rights of a third party in or to
such Proprietary Rights.

        4.22.   Taxes.

                        (a)     Except as otherwise set forth on Schedule 4.22,
all returns, declarations, reports, estimates, statements, schedules or other
information or documents with respect to Taxes (collectively, "Tax Returns")
required to be filed by Seller have been timely filed (giving effect to
extensions granted with respect thereto), and all such Tax Returns are true,
correct, and complete in all material respects.

                        (b)     Seller has timely paid all Taxes due from it or
claimed to be due from it by any federal, state, local, foreign or other taxing
authority.

                        (c)     There are no liens for Taxes upon any of the
assets of, or interest in Seller, except liens for taxes not yet due and
payable.


<PAGE>   29
                        (d)     No Tax Returns of Seller have been audited by
the relevant taxing authority. No deficiency for any Taxes has been proposed,
asserted or assessed against Seller that has not been resolved and paid in full.
There are no outstanding waivers, extensions, or comparable consents regarding
the application of the statute of limitations with respect to any Taxes or Tax
Returns that have been given by Seller (including the time for filing of Tax
Returns or paying Taxes) and Seller has no pending requests for any such
waivers, extensions, or comparable consents.

                        (e)     No audit or other proceeding by any federal,
state, local or foreign court, governmental, regulatory, administrative or
similar authority is presently pending with respect to any Taxes or Tax Return
of Seller, and Seller has not received written notice of any pending audits or
proceedings.

                        (f)     Seller has established adequate reserves in
accordance with generally accepted accounting principles for all Taxes not yet
due and payable, which reserves are set forth in Schedule 4.22.

                        (g)     Seller has not received a ruling from any taxing
authority or signed an agreement with any taxing authority that could reasonably
be expected to have a material adverse effect on Seller or its assets.

                        (h)     Except as otherwise set forth on Schedule 4.22,
Seller has complied in all material respects with all applicable laws, rules and
regulations relating to the payment and withholding of Taxes (including, without
limitation, withholding of Taxes pursuant to Sections 1441, 1442, 1445 and 1446
of the Code or similar provisions under any applicable state and foreign laws)
and has, within the time and the manner prescribed by law, paid over to the
proper governmental authorities all amounts so withheld.

                        (i)     Seller is not a party to and is not bound by or
has any obligation under any Tax sharing allocation or indemnity agreement or
similar contract or arrangement.

                        (j)     Seller is, and has been at all times since its
formation, properly characterized as an "S Corporation" for federal and
applicable state and local income tax purposes.

                        (k)     No power of attorney granted by Seller with
respect to any Taxes is currently in force.

                        (l)     Seller is not subject to any joint venture,
partnership or other arrangement or contract that is treated as a partnership
for U.S. federal income tax purposes.

                        (m)     Except as otherwise set forth in Schedule 4.22,
there is no expectation that any taxing authority may claim or assess any
material amount of Taxes payable by Seller for any period ending on or prior to
the Closing Date and there are no facts of which Seller or the Shareholders are
aware which would constitute grounds for the assessment of any material amount
of Taxes payable by Seller for any period ending on or prior to the Closing
Date.


<PAGE>   30
                        (n)     Seller is not subject to liability as a
transferee pursuant to Code Section 6901 et seq. or otherwise, nor will Buyer,
Nextera or Holdings be subject to such liability as a direct or indirect result
of Buyer's acquisition of the Assets.

                        (o)     None of the Assets is "tax-exempt use property"
within the meaning of Section 168(h) of the Code.

                        (p)     Seller is not a person other than a United
States person within the meaning of the Code.

                        (q)     The transaction contemplated herein is not
subject to the tax withholding provisions of Section 3406 of the Code, or of
Subchapter A of Chapter 3 of the Code or of any other provision of law.

        4.23.   Employee Benefit Programs

                        (a)     Schedule 4.23 lists every Employee Program (as
defined below) that has been maintained (as defined below) by Seller at any time
during the three-year period ending on the date of the Closing.

                        (b)     Each Employee Program which has ever been
maintained by Seller and which has at any time been intended to qualify under
Section 401(a) of the Code, and each associated trust which at any time has been
intended to be exempt from taxation pursuant to Section 501(a) of the Code is
the subject of a favorable determination, opinion or approval letter from the
Internal Revenue Service ("IRS") regarding its qualification or exemption from
taxation, as applicable, under such section and has, in fact, been qualified or
tax exempt, as applicable, under the applicable section of the Code for all
periods for which the applicable statute of limitations has not expired through
and including the Closing (or, if earlier, the date that all of such Employee
Program's assets were distributed). No event or omission has occurred which
would cause any such Employee Program to lose its qualification under the
applicable Code section.

                        (c)     Seller does not know and has no reason to know,
of any failure of any party to comply in any material respect with any laws
applicable to the Employee Programs that have been maintained by Seller. With
respect to any Employee Program ever maintained by Seller for all periods for
which the applicable statute of limitations has not expired, there has occurred
no "prohibited transaction," as defined in Section 406 of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA") or Section 4975 of
the Code, or any material violation of, or material breach of any duty under,
ERISA or other applicable law (including, without limitation, any health care
continuation requirements (under part 6 of subtitle B of Title I or ERISA, or
otherwise) or any other tax law requirements, or conditions to favorable tax
treatment, applicable to such plan), which could result, directly or indirectly,
in any taxes, penalties or other liability to Seller, Buyer or Nextera. No
litigation, arbitration, or governmental administrative proceeding (or
investigation) or other proceeding (other than those relating to routine claims
for benefits) is pending or, to the knowledge of Seller, threatened with respect
to any Employee Program.


<PAGE>   31
                        (d)     Neither Seller nor any ERISA Affiliate (as
defined below) has ever (i) maintained any Employee Program which has been
subject to Title IV of ERISA; (ii) maintained any Multiemployer Plan (as defined
below); or (iii) provided health care or any other non-pension benefits to any
employees after their employment is terminated (other than as required by part 6
of subtitle B of title I of ERISA or benefits that continue for a brief period
of time after termination of employment, for example for the balance of the
month in which an employee terminates, or has ever promised to provide such
post-termination benefits).

                        (e)     With respect to each Employee Program maintained
by Seller within the three years preceding the Closing, complete and correct
copies of the following documents (if applicable to such Employee Program) have
previously been delivered to Nextera: (i) all documents embodying or governing
such Employee Program, and any funding medium for the Employee Program
(including, without limitation, trust agreements) as they may have been amended;
(ii) the most recent IRS determination, opinion or approval letter with respect
to such Employee Program under Code Sections 401 and 501(a), and any
applications for determination or approval subsequently filed with the IRS;
(iii) the three most recently filed IRS Forms 5500, with all applicable
schedules and accountants' opinions attached thereto; (iv) the summary plan
description for such Employee Program (or other descriptions of such Employee
Program provided to employees) and all modifications thereto; (v) any insurance
policy (including any fiduciary liability insurance policy) related to such
Employee Program; (vi) any documents evidencing any loan to an Employee Program
that is a leveraged employee stock ownership plan; and (vii) all other materials
reasonably necessary for Buyer to perform any of its responsibilities with
respect to any Employee Program subsequent to the Closing (including, without
limitation, health care continuation requirements).

                        (f)     Neither Seller nor any ERISA Affiliate has any
announced plan or legally binding commitment to create any additional Employee
Program which is intended to cover employees or former employees of Seller or
any ERISA Affiliate (with respect to their relationship with such entities) or
to amend or modify any existing Employee Program which covers or has covered
employees or former employees of Seller or any ERISA Affiliate (with respect to
their relationship with such entities).

                        (g)     Each Employee Plan listed on Schedule 4.23 may
be amended, terminated, modified or otherwise revised prospectively by Seller
including the elimination of any and all future benefit accruals under any
Employee Plan.

                        (h)     No event has occurred in connection with which
Seller, any ERISA Affiliate or any Employee Program, directly or indirectly,
could be subject to any material liability (A) under any statute, regulation or
governmental order relating to any Employee Programs or (B) pursuant to any
obligation of Seller or any ERISA Affiliate to indemnify any person against
liability incurred under any such statute, regulation or order as they relate to
the Employee Programs.

                        (i)     Except as described on Schedule 4.23, neither
the execution and delivery of this Agreement by Seller nor the consummation of
the transactions contemplated hereby will result in the acceleration or creation
of any rights of any person to benefits under any


<PAGE>   32
Employee Program (including, without limitation, the acceleration of the vesting
or exercisability of any stock options, the acceleration of the vesting of any
restricted stock, or the acceleration or creation of any rights under any
severance, parachute or change in control agreement).

                        (j)     Each Employee Program and related trust
agreement or other funding instrument, as applicable, which covers or has
covered employees or former employees of Seller or any ERISA Affiliate (with
respect to their relationship with such entities) is legally valid and binding
and in full force and effect.

                        (k)     There is no contract, agreement, plan or
arrangement covering any employee or former employee of Seller or any ERISA
Affiliate (with respect to its relationship with such entities) that,
individually or collectively, provides for the payment by Seller or any ERISA
Affiliate of any amount (i) that is not deductible under Section 162(a)(1) or
404 of the Code or (ii) that is an "excess parachute payment" pursuant to
Section 280G of the Code.

                        (l)     All contributions required to be made by Seller
or any ERISA Affiliate with respect to any Employee Program due as of any date
through and including the Closing Date have been made when due.

                        (m)     For purposes of this section:

                                (i)     "Employee Program" means (A) any
employee benefit plan within the meaning of ERISA Section 3(3), including, but
not limited to, any multiple employer welfare arrangement (within the meaning of
ERISA Section 3(4)), plan to which more than one unaffiliated employer
contributes and any employee benefit plan (such as a foreign or excess benefit
plan) which is not subject to ERISA; and (B) any employment, consulting,
severance or other similar contract, arrangement or policy, any stock option
plan, bonus or incentive award plan, deferred compensation agreement,
supplemental income arrangement, vacation plan, any employee benefit arrangement
described in Code Section 501(c)(9), and any other employee benefit plan,
agreement, and arrangement not described in (A) above. In the case of an
Employee Program funded through a trust described in Code Section 501(a), each
reference to such Employee Program shall include a reference to such trust.

                                (ii)    An entity "maintains" an Employee
Program if such entity sponsors, contributes to, or provides (or has promised to
provide) benefits under such Employee Program, or has any obligation (by

cause, or restrict Buyer in the exercise of its independent business judgment in
modifying any of the terms and conditions of the employment of the Rehired
Employees.

                        (d)     No provision of this Agreement shall create any

dependents thereof, or any collective bargaining representative thereof, with
respect to the compensation, terms and conditions of employment and benefits
that may be provided to any Rehired Employee by Buyer or under any benefit plan
which Buyer may maintain.

                        (e)     Seller shall not, directly or indirectly, hire
or offer employment to or seek to hire or offer employment to any employee of

        7.9.    Holdings Class A Units. Holdings agrees that, in connection

to the public, or to otherwise deceive the public. Such amendment shall be in a
form acceptable for filing with the Secretary of State of the Commonwealth of
Massachusetts.

        9.10.   Permits. Buyer shall have obtained or been granted the right to
use all Permits necessary to its operation of the Business.

        9.11.   Escrow Agreement. Seller and the Shareholders shall have
executed and delivered the Escrow Agreement in substantially the form attached

        9.13.   Consent to Recapitalization. Each of the members of Nextera
shall have delivered to Nextera a signed letter of consent acknowledging his
agreement and consent to the Recapitalization (as defined in Section 14.1).

                                   ARTICLE X.

                             CONSENTS TO ASSIGNMENT

        10.1.   Consents to Assignment. Anything in this Agreement to the
contrary notwithstanding, this Agreement shall not constitute an agreement to
assign any Contract, Lease, Permit or any claim or right or any benefit arising
thereunder or resulting therefrom if an attempted assignment thereof, without
the consent of a third party thereto, would constitute a Default thereof or in
any way adversely affect the rights of Buyer thereunder. If such consent is not
obtained, or if an attempted assignment thereof would be ineffective or would
affect the rights thereunder so that Buyer would not receive all such rights,
Seller


<PAGE>   53
will cooperate with Buyer, in all reasonable respects, to provide to Buyer the
benefits under any such Contract, Lease, Permit or any claim or right, including
without limitation enforcement for the benefit of Buyer of any and all rights of
Seller and the Shareholders against a third party thereto arising out of the
Default or cancellation by such third party or otherwise. Nothing in this
Section 10.1 shall affect Buyer's right to terminate this Agreement under
Sections 9.2 and 13.1 in the event that any consent or approval to the transfer
of any Asset is not obtained. Any election by Buyer to proceed to the Closing
despite the failure to obtain any such consent, other than the consents of Pass
& Weisz, Inc. with respect to that certain Lease Agreement dated April 25, 1996
and Greentree Vender Services Corporation with respect to that certain Rental
Agreement dated April 14, 1997, shall constitute a waiver of any and all rights
of Seller, Nextera and/or Holdings with respect to the failure.

                                   ARTICLE XI.

                  RIGHTS AND OBLIGATIONS SUBSEQUENT TO CLOSING

        11.1.   Collection of Accounts Receivable and Letters of Credit. At the
Closing, Buyer will acquire hereunder, and thereafter Buyer or its designee
shall have the right and authority to collect for Buyer's or its designee's
account, all receivables, letters of credit and other items which constitute a
part of the Assets, and Seller and the Shareholders shall within promptly after
receipt of any payment in respect of any of the foregoing, properly endorse and
deliver to Buyer any letters of credit, documents, cash or checks received on
account of or otherwise relating to any such receivables, letters of credit or
other items. Seller and the Shareholders shall promptly transfer or deliver to
Buyer or its designee any cash or other property that Seller or any Shareholders
may receive in respect of any deposit, prepaid expense, claim, contract,
license, lease, commitment, sales order, purchase order, letter of credit or
receivable of any character, or any other item, constituting a part of the
Assets.

        11.2.   Books and Records; Tax Matters.

                        (a)     Books and Records. Each party agrees that it
will cooperate with and make available to the other party, during normal
business hours, all Books and Records, information and employees (without
substantial disruption of employment) retained and remaining in existence after
the Closing which are necessary or useful in connection with any tax inquiry,
audit, investigation or dispute, any litigation or investigation or any other
matter requiring any such Books and Records, information or employees for any
reasonable business purpose. The party requesting any such Books and Records,
information or employees shall bear all of the out-of-pocket costs and expenses
(including without limitation attorneys' fees, but excluding reimbursement for
salaries and employee benefits) reasonably incurred in connection with providing
such Books and Records, information or employees.

                        (b)     Cooperation and Records Retention. Seller, the
Shareholders and Buyer shall (i) each provide the others with such assistance as
may reasonably be requested by any of them in connection with the preparation of
any Tax Return, audit, or other examination by any taxing authority or judicial
or administrative proceedings relating to Liability for Taxes, (ii) each retain
and provide the others with any records or other information that may be
relevant 


<PAGE>   54
to such Tax Return, audit or examination, proceeding or determination, and (iii)
each provide the others with any final determination of any such audit or
examination, proceeding, or determination that affects any amount required to be
shown on any Tax Return of the other for any period. Without limiting the
generality of the foregoing, Seller, the Shareholders and Buyer shall each
retain, until the applicable statutes of limitations (including any extensions)
have expired, copies of all Tax Returns, supporting work schedules, and other
records or information that may be relevant to such Tax Returns for all tax
periods or portions thereof ending on or before the Closing Date and shall not
destroy or otherwise dispose of any such records without first providing the
other party with a reasonable opportunity to review and copy the same.

                        (c)     Preparation of Form W-2's. Pursuant to Revenue
Procedure 84-77 (1984-2 C.B. 753), provided that Seller provides Buyer with all
necessary payroll records for the calendar year which includes the Closing Date,
Buyer shall furnish a Form W-2 to each employee employed by Buyer who had been
employed by Seller disclosing all wages and other compensation paid for such
calendar year, and taxes withheld therefrom, and Seller shall be relieved of the
responsibility to do so.

                        (d)     Payment of Liabilities. Following the Closing
Date, Seller and the Shareholders shall pay promptly when due all of the debts
and Liabilities of Seller, including any Liability for Taxes, other than Assumed
Liabilities; provided, however, this covenant shall not apply to that portion
(or all) of any debt that Seller is contesting in good faith. Following the
Closing Date, Buyer shall pay promptly when due all of the Assumed Liabilities;
provided, however, this covenant shall not apply to that portion (or all) of any
Liability that Buyer is contesting in good faith.

        11.3.   Survival of Representations, Etc. Each of the representations,
warranties, agreements, covenants and obligations herein are material, shall be
deemed to have been relied upon by the other party and shall survive the Closing
regardless of any investigation and shall not merge in the performance of any
obligation by either party hereto; provided, however, that such representations
and warranties shall expire on the same dates as and to the extent that the
rights to indemnification with respect thereto under Article XII shall expire.


<PAGE>   55
                                  ARTICLE XII.

                                 INDEMNIFICATION

        12.1.   Indemnification by Seller and the Shareholders. Seller and each
of the Shareholders agrees subsequent to the Closing to indemnify and hold
Buyer, Nextera, Holdings, and their respective subsidiaries and affiliates and
persons serving as officers, directors, partners, managers, shareholders,
members, employees and agents thereof (other than the Shareholders, except to
the extent of Liabilities incurred in their capacities as an officer, director
or employee of Buyer after the Closing) (individually a "Buyer Indemnified
Party" and collectively the "Buyer Indemnified Parties") harmless from and
against any Damages which may be sustained or suffered by any of them arising
out of or based upon any of the following matters:

                        (a)     fraud, intentional misrepresentation or the
cause or knowledge of a deliberate or willful breach of any representations,
warranties or covenants of Seller or any of the Shareholders under this
Agreement or in any certificate, schedule or exhibit delivered pursuant hereto
(collectively, "Fraud Claims");

                        (b)     any breach of any representation or warranty of
the Shareholders set forth in Section 5.1 of this Agreement (collectively,
"Ownership Claims");

                        (c)     except for the Assumed Liabilities, any
liability of Seller or the Shareholders for Taxes arising from the activities of
Seller and all events and transactions on or prior to the Closing and any breach
of the representations and warranties set forth in Section 4.22 hereof and any
covenant with respect to Taxes or tax related matters (collectively, "Tax
Claims");

                        (d)     except for the Assumed Liabilities, any Excluded
Liability and any Liability imposed upon Buyer by reason of Buyer's status as
transferee of the Business or the Assets (collectively, "Excluded Liability
Claims");

                        (e)     other than Fraud Claims, Ownership Claims, Tax
Claims or Excluded Liability Claims, any other breach of any representation,
warranty or covenant of Seller or the Shareholders under this Agreement or in
any schedule or exhibit delivered pursuant hereto, or by reason of any claim,
action or proceeding asserted or instituted growing out of any matter or thing
constituting a breach of such representations, warranties or covenants
(collectively, "General Claims").

                In addition, each Shareholder severally, but not jointly, agrees
subsequent to the Closing to indemnify and hold all Buyer Indemnified Parties
harmless from and against any damages, liabilities, losses, taxes, fines,
penalties, costs, and expenses (including, without limitation, reasonable fees
of counsel) of any kind or nature whatsoever (whether or not arising out of
third-party claims and including all amounts paid in investigation, defense or
settlement of the foregoing) which may be sustained or suffered by any of them
arising out of or based upon fraud, intentional misrepresentation or any breach
(whether or not deliberate or willful) of any representation or warranty of such
Shareholder contained in Section 5, or by reason of any claim, 


<PAGE>   56
action or proceeding asserted or instituted growing out of any matter or thing
constituting a breach of such representation or warranty (collectively,
"Individual Claims").

        12.2.   Limitations on Indemnification by Seller and the Shareholders.
Anything contained in this Agreement to the contrary notwithstanding, the
liability of Seller and the Shareholders to provide any indemnification to any
Buyer Indemnified Party and right of Buyer Indemnified Parties to
indemnification under Section 12.1 (or otherwise) shall be subject to the
following provisions:

                        (a)     No claims for indemnification shall be made
under this Agreement against Seller or any Shareholder, and no indemnification
shall be payable to any Buyer Indemnified Party, with respect to General Claims
after the date which is eighteen (18) months following the Closing.

                        (b)     No claims for indemnification shall be made
under this Agreement against Seller or any Shareholder, and no indemnification
shall be payable to any Buyer Indemnified Party, with respect to any Tax Claim
after expiration of all applicable statutes of limitation with respect to the
Tax that is the subject of the indemnification claim and the expiration of all
applicable statutes of limitation taking into account any extensions thereof
with respect to collection of the Tax.

                        (c)     The aggregate amount to be payable by Seller and
the Shareholders to all Buyer Indemnified Parties for claims for indemnification
with respect to General Claims (including amounts subject to the Escrow
Agreement and any Nextera Class A Units delivered to Nextera in satisfaction of
an indemnification claim) shall in no event exceed Four Million Four Hundred
Seventy-three Thousand Seven Hundred Fifty Dollars ($4,473,750).

                        (d)     The amount payable by a Shareholder to all Buyer
Indemnified Parties for claims for indemnification hereunder (or otherwise)
shall in no event exceed such Shareholder's pro rata share of the total amount
to be paid to all Buyer Indemnified Parties for claims for indemnification
hereunder (or otherwise). The pro rata shares of the Shareholders for purposes
of this paragraph shall be the same percentages as the Shareholders' respective
ownership interests in Seller.

                        (e)     In the event that any claim for indemnification
arises from a breach of representation, warranty or covenant which was made or
undertaken by a Shareholder, by the express terms of this Agreement severally
and not jointly, the Shareholder shall be severally, but not jointly, liable for
indemnification in respect of such a claim.

                        (f)     Seller and the Shareholders shall have no
obligation for indemnification with respect to General Claims hereunder until
aggregate claims for indemnification with respect to General Claims hereunder
exceed $50,000, in which case Seller shall be obligated for indemnification of
all General Claims including the initial $50,000 of such claims.


<PAGE>   57
                        (g)     Claims for indemnification with respect to Fraud
Claims, Ownership Claims, Tax Claims, Excluded Liability Claims and Individual
Claims made under this Agreement by any Buyer Indemnified Party shall not be
subject to any of the limitations set forth in this Section 12.2.

                        (h)     Claims with respect to Damages resulting from
the Seller's election to proceed to the Closing without the waivers, consents
and approvals of Pass & Weisz, Inc. with respect to that certain Lease Agreement
dated April 25, 1996 and Greentree Vender Services Corporation with respect to
that certain Rental Agreement dated April 14, 1997 shall not be subject to the
limitations set forth in this Section 12.2.

        12.3.   Indemnification by Nextera. Buyer, Nextera and Holdings, jointly
and severally agree to indemnify and hold Seller, the Shareholders and their
affiliates and persons serving as officers, directors, partners, managers,
shareholders, members, employees and agents thereof (individually a "Seller
Indemnified Party" and collectively the "Seller Indemnified Parties") harmless
from and against any Damages which may be sustained or suffered by any of them
arising out of or based upon any breach of any representation, warranty or
covenant made by Buyer, Nextera and/or Holdings in this Agreement or in any
certificate delivered by Nextera, Buyer and/or Holdings hereunder, or by reason
of any claim, action or proceeding asserted or instituted growing out of any
matter or thing constituting such a breach.

        12.4.   Limitation on Indemnification by Nextera. Notwithstanding the
foregoing, (a) no indemnification shall be payable to Seller with respect to
claims asserted pursuant to Section 12.3 above after the date which is eighteen
months after the Closing and the aggregate amount to be payable to Seller
pursuant to Section 12.3 shall not exceed Four Million Four Hundred
Seventy-three Thousand Seven Hundred Fifty Dollars ($4,473,750) and (b) Buyer,
Nextera and Holdings shall have no obligation for indemnification hereunder
until aggregate claims for indemnification hereunder exceed $50,000, in which
case Buyer, Nextera and/or Holdings shall be obligated for indemnification of
all claims, including the initial $50,000 of such claims. Claims for
indemnification with respect to fraud, intentional misrepresentation or the
cause or knowledge of a deliberate or willful breach of any representations,
warranties or covenants of Buyer, Nextera and/or Holdings under this Agreement
or in any certificate, schedule or exhibit delivered pursuant hereto shall not
be subject to any of the limitations set forth in this Section 12.4. Claims with
respect to Damages resulting from any failure by Buyer to pay any Assumed
Liabilities pursuant to Section 2.2 or failure by Buyer, Nextera and/or Holdings
to perform any covenants required to be performed after the Closing shall not be
subject to the limitations set forth in this Section 12.4.

        12.5.   Notice; Defense of Claims. An indemnified party shall make
claims for indemnification hereunder by giving written notice thereof to the
indemnifying party promptly on discovery and in any event within the period in
which indemnification claims can be made hereunder. If indemnification is sought
for a claim or liability asserted by a third party, the indemnified party shall
also give written notice thereof to the indemnifying party promptly after it
receives notice of the claim or liability being asserted, but the failure to do
so shall not relieve the indemnifying party from any liability except to the
extent that it is prejudiced by the failure or delay in giving such notice. Such
notice shall summarize the bases for the claim for 


<PAGE>   58
indemnification and any claim or liability being asserted by a third party.
Within 20 days after receiving such notice the indemnifying party shall give
written notice to the indemnified party stating whether it disputes the claim
for indemnification and whether it will defend against any third party claim or
liability at its own cost and expense. If the indemnifying party fails to give
notice that it disputes an indemnification claim within 20 days after receipt of
notice thereof, it shall be deemed to have accepted and agreed to the claim,
which shall become immediately due and payable. The indemnifying party shall be
entitled to direct the defense against a third party claim or liability with
counsel selected by it (subject to the consent of the indemnified party, which
consent shall not be unreasonably withheld) as long as the indemnifying party is
conducting a good faith and diligent defense. The indemnified party shall at all
times have the right to fully participate in the defense of a third party claim
or liability at its own expense directly or through counsel; provided, however,
that if the named parties to the action or proceeding include both the
indemnifying party and the indemnified party and the indemnified party is
advised that representation of both parties by the same counsel would be
inappropriate under applicable standards of professional conduct, the
indemnified party may engage separate counsel at the expense of the indemnifying
party. If no such notice of intent to dispute and defend a third party claim or
liability is given by the indemnifying party, or if such good faith and diligent
defense is not being or ceases to be conducted by the indemnifying party, the
indemnified party shall have the right, at the expense of the indemnifying
party, to undertake the defense of such claim or liability (with counsel
selected by the indemnified party), and to compromise or settle it, exercising
reasonable business judgment. If the third party claim or liability is one that
by its nature cannot be defended solely by the indemnifying party, then the
indemnified party shall make available such information and assistance as the
indemnifying party may reasonably request and shall cooperate with the
indemnifying party in such defense, at the expense of the indemnifying party.

        12.6.   Satisfaction of Seller and Shareholder Indemnification
Obligations. In order to satisfy the indemnification obligations of Seller and
the Shareholders hereunder, a Buyer Indemnified Party shall proceed first
directly against the Escrow Deposit as further set forth in the Escrow Agreement
and then directly against Seller and each Shareholder subject to the limitations
set forth herein. As further set forth in the Escrow Agreement, all claims
against the Escrow Deposit shall be satisfied first against the cash portion
thereof and then against the Nextera Class A Units.

        12.7.   Bulk Sales. It may not be practicable to comply or attempt to
comply with the procedures of the "Bulk Sales Act" or similar law of any or all
of the states in which the Assets are situated or of any other state which may
be asserted to be applicable to the transactions contemplated hereby.
Accordingly, to induce Buyer to waive any requirements for compliance with any
or all of such laws, Seller and each of the Shareholders hereby agree that the
indemnity provisions of Article XII hereof shall apply to any Damages of Buyer
arising out of or resulting from the failure of Seller or Buyer to comply with
any such laws.

        12.8.   Valuation of Buyer Class A Units. Except as provided in the
Escrow Agreement, Seller and the Shareholders may, at their option, elect to
satisfy any indemnification claims under this Agreement by delivering Nextera
Class A Units to the Buyer Indemnified Parties. To the 


<PAGE>   59
extent that Nextera Class A Units are used to satisfy indemnification
obligations under this Agreement, such units shall be valued in accordance with
the terms of the Escrow Agreement.

        12.9.   Exclusive Remedy. Other than Fraud Claims, the foregoing
indemnification provisions in this Article XII shall be the exclusive remedy for
any breach of the representations and warranties of the Seller and the
Shareholders in Articles IV and V and of Buyer, Nextera and Holdings in Article
VI above.

                                  ARTICLE XIII.

                   TERMINATION OF AGREEMENT; RIGHTS TO PROCEED

        13.1.   Termination. At any time prior to the Closing, this Agreement
may be terminated as follows:

                                (i)     by mutual written consent of all of the
parties to this Agreement;

                                (ii)    by Buyer, Nextera or Holdings, pursuant
to written notice by Nextera to Seller, if any of the conditions set forth in
Article IX of this Agreement have not been satisfied at or prior to the Closing,
or if it has become reasonably and objectively certain that any of such
conditions, other than a condition within the control of Seller or the
Shareholders, will not be satisfied at or prior to the Closing, such written
notice to set forth such conditions which have not been or will not be so
satisfied; and

                                (iii)   by Seller or the Shareholders, pursuant
to written notice by Seller or the Shareholders to Buyer, Nextera and Holdings,
if any of the conditions set forth in Article VIII of this Agreement have not
been satisfied at or prior to the Closing, or if it has become reasonably and
objectively certain that any of such conditions, other than a condition within
the control of Buyer, Nextera and Holdings, will not be satisfied at or prior to
the Closing, such written notice to set forth such conditions which have not
been or will not be so satisfied.

        13.2.   Effect of Termination. All obligations of the parties hereunder
shall cease upon any termination pursuant to Section 13.1, provided, however,
that the provisions of this Article XIII, Section 14.2 and Section 14.11 hereof
shall survive any termination of this Agreement.

                                  ARTICLE XIV.

                                  MISCELLANEOUS

        14.1.   Recapitalization. Seller and each of the Shareholders hereby
agree and acknowledge that they have been informed that Nextera and Holdings
have adopted a recapitalization plan (the "Recapitalization") which has not yet
been effectuated. It is the intention of Nextera, Holdings, and their members to
effectuate the Recapitalization as soon as practicable following the Closing.
Seller and each of the Shareholders hereby consents and agrees to each and every
element of the Recapitalization which is set forth on Schedule 14.1 attached


<PAGE>   60
hereto; the results of the Recapitalization are shown on Exhibit K attached
hereto in the form of a structure chart. Nextera and each Shareholder agree and
acknowledge that the terms of the Recapitalization as set forth on Schedule 14.1
and illustrated in Exhibit K do not incorporate or reflect the fact that there
are employee equity participation rights (" Nextera SARs") in Nextera which may
be converted into Class A Common Units of Nextera. There are currently 944,000
Nextera SARs outstanding with an equivalent strike price of $5.00 per unit and
927,010 Nextera SARs outstanding with an equivalent strike price of $7.50 per
unit and additional Nextera SARs may be issued. Additional Class A Common Units
of Nextera may be issued in future acquisitions. In addition, the terms of the
Recapitalization as set forth on Schedule 14.1 and illustrated on Exhibit K have
been prepared on the assumption that both this transaction and the so-called
"Pyramid" Transaction will be consummate; in the event that the "Pyramid"
Transaction does not close either prior to or after the Recapitalization, then
the terms of the Recapitalization will be adjusted accordingly. Seller and each
Shareholder further agree and acknowledge that no further consents need be
obtained from them to effectuate the Recapitalization after the Closing Date and
that they agree and consent to the necessary steps that will be taken and to the
documentation that will be prepared and executed to complete the
Recapitalization.

        14.2.   Fees and Expenses. Except as otherwise specified in this
Agreement, each party hereto shall pay its own legal, accounting, out-of-pocket
and other expenses incident to this Agreement and to any action taken by such
party in preparation for carrying this Agreement into effect.

        14.3.   Governing Law. This Agreement shall be construed under and
governed by the internal laws of the Commonwealth of Massachusetts without
regard to its conflict of laws provisions.

        14.4.   Notices. Any notice, request, demand or other communication
required or permitted hereunder shall be in writing and shall be deemed to have
been given if delivered or sent by facsimile transmission, upon receipt, or if
sent by registered or certified mail, upon the sooner of the date on which
receipt is acknowledged or the expiration of three days after deposit in United
States post office facilities properly addressed with postage prepaid. All
notices to a party will be sent to the addresses set forth below or to such
other address or person as such party may designate by notice to each other

Any notice given hereunder may be given on behalf of any party by his counsel or
other authorized representatives.

        14.5.   Entire Agreement. This Agreement, including the schedules and
exhibits hereto, reflects the entire agreement of the parties with respect to
its subject matter, and supersedes all previous written or oral negotiations,
commitments and writings. No promises, representations, understandings,
warranties and agreements have been made by any of the parties hereto except as
referred to herein or in such schedules and exhibits; and all inducements to the
making of this Agreement relied upon by either party hereto have been expressed
herein or in such schedules or exhibits.

        14.6.   Assignability; Binding Effect. This Agreement shall only be
assignable by Buyer, Nextera or Holdings to an entity controlling, controlled by
or under common control with Buyer, Nextera or Holdings upon written notice to
Seller. This Agreement may not be assigned by Seller without the prior written
consent of Nextera. This Agreement shall be binding upon and enforceable by, and
shall inure to the benefit of, the parties hereto and their respective
successors and permitted assigns. Assignment of this Agreement by any party
shall not relieve such party from its obligations hereunder.

        14.7.   Captions and Gender. The captions in this Agreement are for
convenience only and shall not affect the construction or interpretation of any
term or provision hereof. The use in this Agreement of the masculine pronoun in
reference to a party hereto shall be deemed to include the feminine or neuter,
as the context may require.

        14.8.   Execution in Counterparts. For the convenience of the parties
and to facilitate execution, this Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which shall
constitute one and the same document.

        14.9.   Amendments. This Agreement may not be amended or modified, nor
may compliance with any condition or covenant set forth herein be waived, except
by a writing duly and validly executed by each party hereto, or in the case of a
waiver, the party waiving compliance.

        14.10.  Publicity and Disclosures. No press releases or public
disclosure, either written or oral, of the transactions contemplated by this
Agreement, shall be made by a party to this Agreement without the prior
knowledge and written consent of Nextera and Seller.

        14.11.  Specific Performance. The parties agree that it would be
difficult to measure damages which might result from a breach of this Agreement
by Seller or any of the Shareholders and that money damages would be an
inadequate remedy for such a breach. Accordingly, if there is a breach or
proposed breach of any provision of this Agreement by Seller or any of the
Shareholders, and Buyer, Nextera or Holdings do not elect to terminate under
Article XIII, Buyer, Nextera and Holdings shall be entitled, in addition to any
other remedies which it may have, to an injunction or other appropriate
equitable relief to restrain such breach without having to show or prove actual
damage to Buyer, Nextera or Holdings.

        14.12.  Obligations. All obligations of Buyer, Nextera and Holdings
hereunder or under any agreement executed in connection herewith shall be joint
and several obligations of Buyer, Nextera and Holdings.


<PAGE>   64
        14.13.  Agent of Sellers. The Shareholders hereby appoint Mason Tenaglia
as their sole and exclusive agent (the "Agent") with respect to this Agreement
and the Escrow Agreement. In his capacity as agent, the Agent shall be
authorized, in his discretion, to consent to such amendments, modifications,
waivers and revisions to this Agreement on behalf of the Shareholders as are
approved by the Agent, and to take any and all actions on behalf of the
Stockholders, including without limitation executing closing certificates and
documents, and his signature shall be sufficient to evidence the approval of the
Shareholders thereto. No Shareholder shall take any action with respect to this
Agreement or the matters contemplated hereby without the approval of the Agent.
The Agent shall not be liable to any Shareholder for any action taken by him in
good faith pursuant to this Agreement, and the Shareholders shall jointly and
severally indemnify the Agent from any losses, claims, damages and expenses
arising out of his service as agent hereunder. The Agent may resign at any time
on 20 days prior notice.


<PAGE>   65
IN WITNESS WHEREOF, the parties have caused this Agreement to be executed by
their duly authorized representatives, as of the date first written above.

                                                               EXHIBIT NO. 10.9

                                ESCROW AGREEMENT

                  This Escrow Agreement (the "Agreement") is entered into as of
March 31, 1998 by and among The Planning Technologies Group, L.L.C., a Delaware
limited liability company ("Buyer"), Nextera Enterprises, L.L.C., a Delaware
limited liability company and the controlling member of Buyer ("Nextera"),
Nextera Enterprises Holdings, L.L.C., a Delaware limited liability company and
the controlling member of Nextera ("Holdings"), The Planning Technologies Group,
Inc., a Massachusetts corporation ("Seller"), the holders of Seller's common
stock listed on Exhibit A attached hereto (herein collectively referred to as
the "Shareholders" and individually as a "Shareholder") and Chase Manhattan
Trust Company, National Association, as escrow agent (the "Escrow Agent").

                  WHEREAS, pursuant to an Asset Purchase Agreement (the
"Purchase Agreement") dated as of March 31, 1998 by and among Buyer, Nextera,
Holdings, Seller and the Shareholders, Buyer is purchasing certain assets and
assuming certain liabilities from Seller;

                  WHEREAS, Seller and the Shareholders have agreed to indemnify
Buyer, Nextera and Holdings against certain breaches of the representations,
warranties and covenants made by Seller and the Shareholders in the Purchase
Agreement and against certain other matters as specified in Article XII of the
Purchase Agreement; and

                  WHEREAS, to secure payment of the Shareholders'
indemnification obligations, ONE MILLION SIX THOUSAND FIVE HUNDRED DOLLARS
($1,006,500) in cash (the "Escrowed Cash") and 32,100 Nextera Class A Units (the
"Escrowed Units") (together, the Escrowed Cash and the Escrowed Units and
additions to or earnings on the same, the "Escrow Deposit") are being deposited,
pursuant to Section 2.4 of the Purchase Agreement, in escrow to be held as
hereinafter provided.

                  NOW, THEREFORE, in consideration of the foregoing and the
mutual promises of the parties herein contained, and other good and valuable
consideration, receipt and sufficiency of which is hereby acknowledged, the
parties hereto agree as follows:

                  1. Establishment of Escrow: Investment. Buyer has herewith
deposited the Escrow Deposit with the Escrow Agent on the date of the Closing.
The Escrowed Units have been issued in the name of Seller, or at the direction
of Seller, the names of the Shareholders, and shall be accompanied by stock
powers or similar instruments duly signed in blank by Seller or the
Shareholders, as appropriate. The Escrow Deposit shall be held in escrow in an
account designated as The Planning Technologies Group Escrow Account or an
account having such other similar designation, subject to the terms and
conditions set forth herein. Mason Tenaglia shall serve as the exclusive
representative of Seller and the Shareholders with respect to the Escrow Deposit
and this Agreement (the "Escrow Representative"). If, for any reason, the Escrow
Representative shall be either unable or unwilling to serve, a successor Escrow
Representative shall be appointed by written consent of Seller and the
Shareholders and all references to the Escrow Representative shall be deemed to
include such successor. The Escrow Agent shall invest all cash held as part of
the Escrow Deposit only in such specific investments as 

<PAGE>   2

                           acceptances, maturing within ninety (90) days from
                           the date of acquisition thereof, issued by state and
                           national banks located in the United States of
                           America, including the Escrow Agent or any of its

                           aggregating at least one hundred million dollars
                           ($100,000,000);

                  (b)      securities or other obligations of, or guaranteed by,
                           the United States of America or any agency thereof
                           having maturities of not greater than one (1) year;

                  (c)      commercial paper, maturing within ninety (90) days
                           from the date of acquisition thereof, rated A-1 or

                  (d)      repurchase agreements fully collateralized by
                           obligations described in clauses 1(a), 1(b) or 1(c)
                           hereof;

                  (e)      shares of investment companies registered under the
                           Investment Company Act of 1940 which invest in any
                           obligation described herein, or shares of the Vista
                           Prime Money Market Fund, including those for which
                           the Escrow Agent or any of its affiliates provide
                           services for a fee, whether as an investment advisor,

                  Until further written notice, cash in the Escrow Deposit shall
be invested in Vista Prime. Unless otherwise directed in writing by the Escrow
Representative and Buyer, the Escrow Agent shall not invest all or any portion
of the Escrow Deposit in any investment if the maturity date of such investment
is later than the Termination Date (as defined below).

                  2. Amounts Earned on Escrow Deposit: Tax Matters. All amounts
earned, paid or distributed with respect to the Escrow Deposit (whether
interest, dividends, distributions from Nextera with respect to the Escrowed
Units or otherwise) shall become a part of the Escrow Deposit, shall be held
hereunder upon the same terms as the original Escrow Deposit and shall be
distributed together with the underlying portion of the original Escrow Deposit
pursuant to the terms of this Agreement. The parties agree that to the extent
permitted by applicable law, including Section 468B(g) of the Internal Revenue
Code of 1986, as amended, Seller or the Shareholders, as applicable, will
include all amounts earned on the Escrow Deposit in its/their gross income for
federal, state and local income tax (collectively, "income tax") purposes and
pay any income tax resulting therefrom.

                  3. Claims Against Escrow Deposit.

                  (a) At any time or times prior to the Termination Date (as
hereinafter defined), Buyer may make claims against the Escrow Deposit for
indemnification pursuant to and in accordance with Article XII of the Purchase
Agreement. Buyer shall notify the Escrow Representative and the Escrow Agent in
writing promptly upon determination to make a claim and in any event prior to
the expiration of this Agreement of each such claim, including a summary of the
amount of and bases for such claim. If the Escrow Representative shall dispute
such claim, the Escrow Representative shall give written notice thereof to Buyer
and to the Escrow Agent within thirty (30) days after receipt of notice of
Buyer's claim, in which case the Escrow Agent shall continue to hold the Escrow
Deposit in accordance with the terms of this Agreement; otherwise, such claim
shall be deemed to have been acknowledged to be payable out of the Escrow
Deposit in the full amount thereof and the Escrow Agent shall use its best
efforts to pay such claim to Holdings within three (3) business days after
expiration of said thirty (30) day period or as soon thereafter as possible. If
the amount of the claim exceeds the value of the Escrow Deposit, the Escrow
Agent shall have no liability or responsibility for any deficiency.

                  (b) The Escrow Agent shall follow the procedure below in
making any payment in satisfaction of a claim against the Escrow Deposit:

                           (i) The Escrow Agent shall make such payment first
from the Escrowed Cash and any additions to or earnings on the Escrowed Cash
until all cash in the Escrow Deposit has been exhausted.

                           (ii) To the extent that any claim exceeds the amount
of Escrowed Cash or other cash in the Escrow Deposit, the Escrow Agent shall
make payment from the Escrowed Units in such number of Escrowed Units (computed
to the nearest whole unit) having a value equal to the value of the claim not
satisfied by cash payment. Any payment of Escrowed Units by the Escrow Agent to
Holdings shall be treated as a sale by Seller or the Shareholders, as
applicable, of such Escrowed Units for the value described herein. The value of
an Escrowed Unit for purposes of this Section shall be the fair market value of
such unit on the date of the claim as determined by the Board of Directors of
Nextera (the "Board"). The fair market value shall be determined in good faith
by the Board and the Board shall notify the Escrow Representative and Escrow
Agent in writing of its determination, together with an explanation of how the
value was determined and such supporting data as the Escrow Representative shall
reasonably require (the "Valuation Notice"). If the Escrow Representative
disputes the fair market value of the Escrowed Units as determined by the Board,
then the Escrow Representative shall so notify the Board and Escrow Agent in
writing (the "Appraisal Notice") within ten (10) business days of receipt of the
Valuation Notice. Within twenty (20) business days of the receipt of the
Appraisal Notice, the Board and the Escrow Representative shall each appoint a
professional appraiser to determine the fair market value of the Escrowed Units.
Each appraiser shall have at least five (5) years experience in appraising
companies similar to Nextera. The two appraisers shall within the succeeding
twenty (20) day period after their selection, attempt to reach agreement on the
fair market value. If the appraisers reach such agreement they shall so notify
the Escrow Agent and their agreement shall be final and binding on Buyer,
Nextera, Holdings, the Board, the Escrow Representative, Seller, the
Shareholders, and their affiliates. If 

                                       3


<PAGE>   4

the appraisers fail to agree, they shall within ten (10) days thereafter select
a third appraiser with the same qualification requirements, and the three (3)
appraisers shall establish the fair market value by majority vote within the
succeeding twenty (20) day period and shall notify the Escrow Agent of their
determination. Such determination of the fair market value shall be final and
binding on Buyer, Nextera, Holdings, the Board, the Escrow Representative,
Seller, the Shareholders, and their affiliates. In all events, the appraisers
selected shall be unaffiliated with and otherwise independent of Buyer, Nextera,
Holdings, the Board, the Escrow Representative, Seller, the Shareholders, and
their affiliates. If the fair market value of the Escrowed Units, as determined
by the appraisers, is less than or no more than five percent (5%) greater than
the value as determined by the Board, then the Shareholders shall pay all costs
associated with the appraisers, provided that the Board shall have provided
substantially similar information to the appraisers as that delivered to the
Escrow Representative in the Valuation Notice. If the fair market value as
determined by the appraisers is more than five percent (5%) greater than the
value as determined by the Board, then Buyer shall pay for all costs associated
with the appraisers. To the extent Seller has transferred its rights to the
Escrowed Units to the Shareholders, the Escrowed Units delivered to Holdings in
satisfaction of a claim shall be allocated among the Shareholders so as to
reduce each Shareholder's interest in the remaining Escrowed Units by an equal
proportion. In the event that the Escrow Agent must make payment with a number
of units less than or different from the number of units represented by a
certificate in the Escrow Deposit, the Escrow Agent shall surrender such
certificate to Nextera and Nextera shall issue to the Escrow Agent certificates
of Nextera Class A Units identical in form but for the number of units as
necessary to allow for proper payment of the claim so long as the number of
units of the new certificates plus the amount of units used to satisfy such
claim shall be equivalent to the total number of units covered by the
surrendered certificate.

                  4.  Disputed Claims.

                  (a) If the Escrow Representative shall dispute an
indemnification claim of Buyer as above provided, the Escrow Agent shall set
aside a portion of the Escrow Deposit sufficient to pay said claim in full as
reasonably determined by Buyer in good faith (the "Set Aside Amount"). If Buyer
notifies the Escrow Agent in writing that it has made out-of-pocket expenditures
in connection with any such disputed claim, and provides paid receipts for such
expenditures, in addition to expenditures included in the Set Aside Amount, an
amount equal to such additional expenditures shall be added to the Set Aside
Amount. If the Set Aside Amount exceeds the amount of the Escrowed Cash, the
Escrow Agent shall set aside an appropriate number of Escrowed Units as
determined by the procedure described in Section 3(b)(ii) above.

                  (b) If the disputed indemnification claim has not been
resolved or compromised within sixty (60) days after the Escrow Representative
sends notice of dispute of the same, or in the event of a third-party claim or
suit, within fifteen (15) days after its resolution or compromise, said
indemnification claim shall be referred to the American Arbitration Association,
to be settled by binding arbitration in Boston, Massachusetts, in accordance
with the commercial arbitration rules of the Association. The fees and expenses
of the arbitrator shall be borne equally by Seller and the Shareholders on the
one hand and Buyer on the other. In no event shall the Escrow Agent be
responsible for any fee or expense of any party to any arbitration proceeding.
The determination of the arbitrator as to the amount, if any, of the
indemnification claim which is 

                                       4


<PAGE>   5

properly allowable shall be conclusive and binding upon the parties hereto and
judgment may be entered thereon in any court having jurisdiction thereof,
including, without limitation, any Superior Court in the Commonwealth of
Massachusetts. The arbitrator shall have the authority in its discretion to
award to the prevailing party reasonable costs and expenses including attorney's
fees and the cost of arbitration. The Escrow Agent shall use its best efforts to
make payment of such claim, as and to the extent allowed, to Buyer out of the
Set Aside Amount (or if insufficient, out of the Escrow Deposit) within three
(3) business days following the Escrow Agent's receipt of said determination or
as soon thereafter as possible.

                  (c) Notwithstanding Section 4(b), if a disputed
indemnification claim has not been resolved or compromised as of the Termination
Date (as hereinafter defined), and such claim does not involve a third-party
claim or suit, Buyer and the Escrow Representative shall continue to negotiate
in good faith a settlement of such claims for a period of ten (10) days after
the Termination Date. If, after the expiration of such ten-day period, such
indemnification claim still has not been resolved or compromised, such claim
shall be settled in accordance with the arbitration provisions set forth in
Section 4(b).

                  (d) It is understood and agreed that should any dispute arise
under this Section 4, the Escrow Agent, upon receipt of written notice of such
dispute or claim by the Escrow Representative, is authorized and directed to
retain in its possession without liability to anyone, the Set Aside Amount
relating to such dispute plus any expenditures of Buyer made pursuant to Section
4(a) until such dispute shall have been settled pursuant to this Section 4. The
Escrow Agent may, but shall be under no duty whatsoever to, institute or defend
any legal proceedings which relate to the Escrow Deposit.

                  5. Termination. This Agreement shall terminate on the date
that the Escrow Deposit is reduced to zero as the result of payments by the
Escrow Agent to Holdings in accordance with the provisions of Section 3 or
Section 4. If, however, the Escrow Deposit has not been reduced to zero as of
the date that is eighteen (18) months following the date of this Agreement (the
"Termination Date") and there are no outstanding indemnification claims on the
Termination Date, the Escrow Agent shall distribute the amount remaining in the
Escrow Deposit to the Seller or, to the extent Seller has transferred to the
Shareholders its rights to the Escrow Deposit, the Shareholders and after such
payment this Agreement shall terminate; otherwise this Agreement shall continue
in effect until all indemnification claims Buyer has made pursuant to Section 3
hereof on or prior to the Termination Date shall have been disposed of. As of
the Termination Date, an amount of the Escrow Deposit adequate to cover all
disputed and undisputed claims made by Buyer pursuant to Section 3 hereof, plus
an additional ten percent (10%) of any such amount to cover potential expenses
to be incurred by Buyer associated with such claims, will be held by the Escrow
Agent, and the Escrow Agent shall distribute on the Termination Date the
balance, if any, of the Escrow Deposit to Seller or, to the extent Seller has
transferred to the Shareholders its rights to the Escrow Deposit, the
Shareholders. At such time as all remaining indemnification claims hereunder
have been resolved and the Escrow Agent has received a written notice executed
by Buyer and the Escrow Representative, or notification of a determination of an
arbitrator pursuant to Section 4(b), to that effect and any amounts to be
distributed to Holdings in connection therewith have been so distributed, the
Escrow Agent shall 


                                       5


<PAGE>   6

distribute the remaining Escrow Deposit, if any, to Seller or, to the extent
Seller has transferred to the Shareholders its rights to the Escrow Deposit, the
Shareholders.

                  6. The Escrow Agent.

                  (a) Direction from Buyer and Escrow Representative.
Notwithstanding anything herein to the contrary, the Escrow Agent shall promptly
dispose of all or any part of the Escrow Deposit as directed by a writing signed
by Buyer and Escrow Representative.

                  (b) Reliance by Escrow Agent; Liability of Escrow Agent.
Except with respect to capitalized terms used herein and defined in the Purchase
Agreement, the Escrow Agent will not be subject to, or be obliged to recognize,
any other agreement between the parties hereto or directions or instructions not
specifically set forth as provided for herein. The Escrow Agent will not make
any payment or disbursement from or out of the Escrow Deposit that is not
expressly authorized pursuant to this Agreement. The Escrow Agent undertakes to
perform only such duties as are expressly set forth herein. The Escrow Agent may
rely and shall be protected in acting or refraining from acting upon any written
notice, instruction or request furnished to it hereunder and believed by it to
be genuine and to have been signed or presented by the proper party or parties.
The Escrow Agent shall be under no duty to inquire into or investigate the
validity, accuracy or content of any such document. The Escrow Agent shall have
no duty to solicit any payment which may be due it hereunder. The Escrow Agent
shall not be liable for any action taken or omitted by it in good faith unless a
court of competent jurisdiction determines that the Escrow Agent's gross
negligence and willful misconduct was the primary cause of any loss to Buyer,
Nextera, Holdings, Seller or the Shareholders. In the administration of the
Escrow Deposit hereunder, the Escrow Agent may execute any of its powers and
perform its duties hereunder directly or through agents or attorneys and may
consult with counsel, accountants and other skilled persons to be selected and
retained by it. The Escrow Agent shall not be liable for anything done, suffered
or omitted in good faith by it in accordance with the advice or opinion of any
such counsel, accountants or other skilled persons. Buyer, Nextera, Holdings,
Seller and the Shareholders jointly and severally hereby agree to indemnify and
hold the Escrow Agent and its directors, officers, agents and employees
(collectively, the "Indemnitees") harmless from and against any and all claims,
liabilities, losses, damages, fines, penalties, and expenses, including
out-of-pocket and incidental expenses and legal fees and expenses ("Losses")
that may be imposed on, incurred by, or asserted against the Indemnitees or any
of them for following any instructions or other directions upon which the Escrow
Agent is authorized to rely pursuant to the terms of this Agreement. In addition
to and not in limitation of the immediately preceding sentence, the Buyer,
Nextera, Holdings, Seller and the Shareholders also agree to indemnify and hold
the Indemnitees and each of them harmless from and against any and all Losses
that may be imposed on, incurred by, or asserted against the Indemnitees or any
of them in connection with or arising out of Escrow Agent's performance under
this Agreement, provided the Indemnitees have not acted with gross negligence or
engaged in willful misconduct. Anything in this Agreement to the contrary
notwithstanding, in no event shall the Escrow Agent be liable for special,
indirect or consequential loss or damage of any kind whatsoever (including but
not limited to lost profits). As between Buyer, Nextera and Holdings on the one
hand and Seller and the Shareholders on the other, each shall bear equally the
indemnification obligations set forth in this Section 6(b). The provisions of
this Section 6(b) shall survive the termination of this Agreement and the
resignation or removal of 

                                       6


<PAGE>   7

the Escrow Agent for any reason.

                  (c) Fees and Expenses of the Escrow Agent. All fees of the
Escrow Agent for its services hereunder, together with any expenses reasonably
incurred by the Escrow Agent in connection with this Agreement, shall be shared
equally by Buyer on the one hand and Seller and the Shareholders on the other.
The fees to be paid by Seller and the Shareholders shall be deducted from the
Escrow Deposit.

                  (d) Resignation and Removal of Escrow Agent. Successor 
Escrow Agent.

                           (i) The Escrow Agent may resign from its duties
hereunder by giving each of the parties hereto not less than thirty (30) days
prior written notice of the effective date of such resignation (which effective
date shall be at least thirty (30) days after the date such notice is given). In
addition, the Escrow Agent may be removed and replaced on a date designated in a
written instrument signed by Buyer and the Escrow Representative and delivered
to the Escrow Agent. The parties hereto intend that a successor escrow agent
mutually acceptable to the Escrow Representative and Buyer will be appointed to
fulfill the duties of the Escrow Agent hereunder for the remaining term of this
Agreement in the event of the Escrow Agent's resignation or removal. Upon the
effective date of such resignation or removal, the Escrow Agent shall deliver
the property comprising the Escrow Deposit to such successor escrow agent,
together with an accounting of the investments held by it and all transactions
related to this Agreement, including any distributions made and such records
maintained by the Escrow Agent in connection with its duties hereunder and other
information with respect to the Escrow Deposit as such successor may reasonably
request. If on or before the effective date of such resignation or removal, a
successor escrow agent has not been appointed, the Escrow Agent will thereupon
deposit the Escrow Deposit into the registry of a court of competent
jurisdiction.

                               Upon written acknowledgment by a successor escrow
agent appointed in accordance with this Section 6(d)(i) of its agreement to
serve as escrow agent hereunder and the receipt of the property then comprising
the Escrow Deposit, the Escrow Agent shall be fully released and relieved of all
duties, responsibilities and obligations under this Agreement, except for those
arising under the last sentence of Section 6(b) of this Agreement, and such
successor escrow agent shall for all purposes hereof be the Escrow Agent.

                           (ii) Any corporation, association or other entity
into which the Escrow Agent may be converted or merged, or with which it may be
consolidated, or to which it may sell or otherwise transfer all or substantially
all of its corporate trust business, or any corporation, association or other
entity resulting from any such merger, conversion, consolidation, sale or other
transfer, shall, ipso facto, be and become successor Escrow Agent hereunder,
vested with all of the powers, discretions, immunities, privileges and all other
matters as was its predecessor, without the execution or filing of any
instrument or any further act on the part or any of the parties hereto, anything
herein to the contrary notwithstanding.

                  7. Voting of Escrowed Units. So long as any Escrowed Units are
retained by the Escrow Agent, Seller or, to the extent Seller has transferred to
the Shareholders its rights to 

                                       7


<PAGE>   8

the Escrowed Units, the Shareholders shall be entitled to exercise the voting
power, if any, with respect to in the Escrowed Units.

                  8. Governing Law. IT IS THE PARTIES' INTENT THAT THIS
AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL
LAWS OF THE COMMONWEALTH OF MASSACHUSETTS (WITHOUT REGARD TO PRINCIPLES OF
CONFLICTS OF LAW).

                  9. Counterparts. This Escrow Agreement may be executed in one
or more counterparts, all of which documents shall be considered one and the
same document.

                  10. Notices. Any notice or other communication required or
permitted hereunder shall be in writing and shall be deemed to have been given
when received, if personally delivered or sent by facsimile transmission, or

certified mail, return receipt requested, postage prepaid, addressed as follows:

                  Addresses may be changed by written notice given pursuant to
this Section. Any notice given hereunder may be given on behalf of any party by
his counsel or other authorized representatives.

                  11. Certification of Tax Identification Number. The parties
hereto agree to provide the Escrow Agent with a certified tax identification
number by signing and returning a Form W-9 (or Form W-8, in the case of non-U.S.
persons) to the Escrow Agent prior to the date on which any income earned on the
investment of the Escrow Deposit is credited to the Escrow Deposit. The parties
hereto understand that, in the event their tax identification numbers are not
certified to the Escrow Agent, the Internal Revenue Code, as amended from time
to time, may require withholding of a portion of any interest or other income
earned on the investment of the Escrow Deposit.

                  12. Force Majeure. Neither Buyer, Nextera, Holdings, Seller,
the Shareholders nor the Escrow Agent shall be responsible for delays or
failures in performance under this Agreement resulting from acts beyond its
control. Such acts shall include but not be limited to acts of God, strikes,
lockouts, riots, acts of war, epidemics, governmental regulations superimposed
after the fact, fire, communication line failures, computer viruses, power
failures, earthquakes or other disasters.

                  13. Modifications. This Agreement may not be altered or
modified without the express written consent of the parties hereto, provided
that the Escrow Representative shall be authorized to agree to any amendment,
modification or waiver on behalf of the Shareholders. No course of conduct shall
constitute a waiver of any of the terms and conditions of this Escrow Agreement,
unless such waiver is specified in writing, and then only to the extent so
specified. A waiver of any of the terms and conditions of this Escrow Agreement
on one occasion shall not constitute a waiver of the other terms of this Escrow
Agreement, or of such terms and conditions on any other occasion.

                  14. Reproduction of Documents. This Agreement and all
documents relating thereto, including, without limitation, (a) consents, waivers
and modifications which may hereafter be executed, and (b) certificates and
other information previously or hereafter furnished, may be reproduced by a
photographic, photostatic, microfilm, optical disk, micro-card, miniature
photographic or other similar process. The parties agree that any such
reproduction shall be admissible in evidence as the original itself in any
judicial or administrative proceeding, whether or not the original is in
existence and whether or not such reproduction was made by a party in the
regular course of business, and that any enlargement, facsimile or further
reproduction of such reproduction shall likewise be admissible in evidence.

                  15. Obligations of Buyer. All obligations of Buyer hereunder
shall be joint and several obligations of Buyer, Nextera and Holdings.

                           PURCHASE AND SALE OF ASSETS

               2.1. Sale of Assets. Upon the terms and subject to the conditions
contained herein, at the Closing, Seller will sell, convey, transfer, assign and
deliver to Buyer, and Buyer will purchase and acquire from Seller, the Assets,
free and clear of all Encumbrances other than the Permitted Liens.

               2.2. Assumption of Liabilities. Upon the terms and subject to the
conditions contained herein, at the Closing, Buyer shall assume and agree to pay
when due, perform and discharge in accordance with the terms thereof (a) all

items described on Schedule 7.1 (collectively, the "Assumed Liabilities").


<PAGE>   15
               2.3. Excluded Liabilities. Notwithstanding any other provision of
this Agreement, Buyer shall not assume, or otherwise be responsible for, (a) any
Liabilities of any Selling Party under this Agreement, the Exchange Agreement,
the Escrow Agreement and the other agreements and transactions contemplated
hereby and (b) any Liabilities of Seller or any Subsidiary of Seller in respect
of any Tax, whether liquidated or unliquidated, or known or unknown, whether
arising out of occurrences, in the case of Seller, prior to, at or after the
date hereof and, in the case of any Subsidiary, prior to, at or after the date
hereof until the Closing Date (the "Excluded Liabilities").

               2.4. Purchase Price.

               (a) Purchase Price of Assets. In consideration of the sale,
transfer, assignment, conveyance and delivery of an undivided eighty-five
percent (85%) interest in the Assets by Seller to Buyer and in reliance upon the
representations and warranties of Seller herein contained and made at the
Closing and upon the terms and subject to the satisfaction or waiver by the
party entitled thereto of all of the conditions set forth herein, Buyer agrees
that at the Closing, it will pay to Seller the aggregate amount of Thirty Four
Million Seven Hundred Sixty Three Thousand Nine Hundred Dollars ($34,763,900)
(the "Purchase Price") (to be paid by wire transfer of immediately available
funds) and shall assume the Assumed Liabilities pursuant to this Agreement.

               The Purchase Price shall be allocated among the Assets in the
manner required by Section 1060 of the Code and regulations thereunder. Exhibit
C attached hereto sets forth the amount and form of the Purchase Price allocable
to the various Assets. Buyer and Seller (or General Partner and Limited Partner
on behalf of Seller) agree to each prepare and file on a timely basis with the
Internal Revenue Service substantially identical initial and supplemental
Internal Revenue Service Forms 8594 "Asset Acquisition Statements Under Section
1060" consistent with Exhibit C and which gives effect to any working capital
adjustment determined in accordance with Section 2.5 hereof and to file all
relevant Tax Returns in a manner consistent therewith.

               (b) Contribution of Assets. In consideration of the contribution
of an undivided fifteen percent (15%) interest in the Assets by Seller to Buyer
and in reliance upon the representations and warranties of Seller herein
contained and made at the Closing and upon the terms and subject to the
satisfaction or waiver of all of the conditions set forth herein, Buyer agrees
that at the Closing, it will (i) deliver to Seller the aggregate amount of
1,828,539 Nextera Class A Units issued by Nextera in Seller's name pursuant to
the Nextera Operating Agreement and (ii) deliver to the Escrow Agent 784,548

pursuant to and in accordance with the terms of the Nextera Operating Agreement
and to be held in the manner described in the Escrow Agreement to be executed in
substantially the form attached hereto as Exhibit B. The parties acknowledge
that the value of the Nextera Class A Units is $2.50 per unit.

<PAGE>   16
set forth herein, Buyer agrees that at the Closing, it will pay to General
Partner the aggregate amount of One Hundred Dollars ($100).

               2.5. Working Capital.

               (a) Working Capital Adjustment. The amount of the cash payment to
be made by Buyer for the Assets at the Closing is premised upon Seller
delivering to Buyer at least Three Million One Hundred Thousand Dollars
($3,100,000) of working capital determined in accordance with generally accepted
accounting principles ("GAAP") consistently applied (except as separately agreed
in writing by the parties), at the Closing (such amount being the "Minimum
Working Capital"). No later than two (2) business days prior to the Closing
Date, Seller shall advise Buyer and Nextera of its estimate of working capital
to be delivered at the Closing (the "Estimated Working Capital"). Without
limiting other rights that Buyer and Nextera may have under this Agreement, if
the Estimated Working Capital is less than the Minimum Working Capital, the cash
payment to Seller for the Assets at the Closing shall be reduced by the amount
of such shortfall. Seller shall retain from the Purchase Price, and not
distribute to its General Partner or Limited Partner, the sum of Three Hundred
Thousand Dollars ($300,000) (the "Working Capital Retention") until such time as
the Closing Working Capital (as defined below) has been determined and
reconciled pursuant to this Section 2.5. Within thirty (30) days following the
Closing, Seller shall determine the actual working capital as of the Closing
Date (the "Closing Working Capital") and promptly notify Buyer of such amount.
If the Closing Working Capital is less than the Estimated Working Capital, and
would have resulted in a reduced or further reduced cash payment, as applicable,
to Seller for the Assets at the Closing, Seller shall promptly pay to Buyer the
difference (the "Working Capital Adjustment").

               (b) Disputed Closing Working Capital. If Buyer shall disagree
with the amount determined to be the Closing Working Capital, it shall notify
Seller in writing of such disagreement within fifteen (15) business days of its
receipt of the determination of Closing Working Capital. Buyer and Seller shall
use their commercially reasonable efforts for a period of thirty (30) days
following the notice of disagreement to resolve any disagreement. If at the end
of such period, Buyer and Seller are unable to resolve the disagreement, a
mutually agreed upon independent public accounting firm (the "Arbitrator") shall
be retained to make a final and binding determination of the actual Closing
Working Capital, at which time Seller shall promptly pay to Buyer the Working
Capital Adjustment, if any. The determination of the Arbitrator shall be final,
binding and conclusive on the parties. The fees and expenses of the Arbitrator
shall be borne equally by Buyer and Seller.

               2.6. Closing Costs; Transfer Taxes and Fees. Seller and Nextera
shall each be responsible for one-half of any documentary and transfer taxes and
any sales, use or other taxes imposed by reason of the transfers of the Assets
provided hereunder and any deficiency, interest or penalty asserted with respect
thereto. Seller and Nextera shall each pay one-half of the fees and costs of
recording or filing all applicable conveyancing instruments described in Section
3.2(a). Nextera shall pay all costs of applying for new Permits and obtaining
the transfer of existing Permits which may be lawfully transferred.

which, with notice or the passage of time, or both, would give rise to such a

Facility Lease. With respect to any Facility Lease to which any Subsidiary of
Seller is a party, as lessee or sublessee, the actions contemplated by this
Agreement do not violate the terms or result in the termination of, or create 


<PAGE>   23
a right to terminate, such Facility Lease. To the knowledge of Seller, Seller
and each Subsidiary of Seller enjoys peaceful and undisturbed possession of all
the Leased Real Property, as applicable.

               (e) Condition of Leased Real Property. To the knowledge of Seller

condition and repair (reasonable wear and tear excepted).

of any real estate tax deficiency or assessment nor is aware of any proposed

requirements).

               (f) Neither Seller nor any ERISA Affiliate has any announced plan
or legally binding commitment to create any additional Employee Program which is

(with respect to their relationship with such entities) or to amend or modify
any existing Employee Program which covers or has covered employees or former
employees of Seller or any ERISA Affiliate (with respect to their relationship
with such entities).

"Retiree Welfare Benefit Plans"). Except as set forth on Schedule 4.23(g) no
representative of Seller (or any representative of any predecessor of Seller to
the extent enforceable against Seller) or any ERISA Affiliate, or, to the
knowledge of Seller, any Retiree Welfare Benefit Plan, has made any commitment

ERISA Affiliate to maintain any such Retiree Welfare Benefit Plan or any
benefits thereunder.

               (h) No event has occurred in connection with which Seller, any
ERISA Affiliate or any Employee Program, directly or indirectly, could be

the Employee Programs.

               (i) Except as described on Schedule 4.23, neither the execution
and delivery of this Agreement by Seller or any Subsidiary of Seller nor the
consummation of the transactions contemplated hereby will result in the
acceleration or creation of any rights of any person to benefits under any
Employee Program (including, without limitation, the acceleration of the vesting
or exercisability of any stock options, the acceleration of the vesting of any
restricted stock, or the acceleration or creation of any rights under any
severance, parachute or change in control agreement).

               (j) There is no contract, agreement, plan or arrangement covering
any employee or former employee of Seller or any ERISA Affiliate (with respect
to its relationship with such entities) that, individually or collectively,
provides for the payment by Seller or any ERISA Affiliate of any amount (i) that

Seller or any Subsidiary of Seller on the Business, the Assets or its employees.
All such insurance coverage applicable to Seller or any Subsidiary of Seller,

premiums except in the ordinary course of business and no notice of cancellation
or nonrenewal of any such coverage has been received. There are no provisions in
such insurance policies for retroactive or retrospective premium adjustments.

professional liability (error and omissions), fiduciary liability and employment
practices policies. There are no outstanding performance bonds covering or
issued for the benefit

receivable are subject to no defenses, counterclaims or rights of setoff and are
fully collectible in the ordinary course of business without cost in collection
efforts therefor, except to the extent of the appropriate reserves for bad debts
on accounts receivable as set forth on the Base Balance Sheet and, in the case

               This Agreement and each other agreement, document and instrument
executed and delivered by Buyer and/or Nextera pursuant to this Agreement
constitutes, or when executed and delivered will constitute, valid and binding
obligations of Buyer and/or Nextera, as applicable, enforceable in accordance

other parties thereto), subject to the effect of any applicable bankruptcy,
reorganization, insolvency, moratorium or similar laws affecting creditors'
rights generally and subject to the effect of general principles of equity,

               The execution, delivery and performance by Buyer and Nextera of
this Agreement and each such agreement, document and instrument:

                (i) does not and will not violate any provision of the

        Closing other than (x) any such approval, consent or waiver of or filing
        with respect to which the failure to so obtain will not have a material
        adverse effect and (y) any approvals, consents, waivers or filings in
        connection with Contracts and Leases as a result of the transactions
        contemplated hereby; and

                (iii) does not and will not result in (i) a breach of,

        or its Subsidiaries on a consolidated basis except, in the case of
        clause (i), for such breaches, defaults, accelerations or terminations
        as would not, individually or in the aggregate, have a material adverse
        effect..

no Actions pending or, to the knowledge, of Nextera threatened (a) against (i)

relating to any Environmental Law which regulate, obligate, bind or in any way
affect Nextera or its Subsidiaries.

Buyer, Seller or any of Seller's affiliates to pay any finder's fee, brokerage
fees or commission or similar payment in connection with the transactions
contemplated hereby.

               6.6. Membership Interests of Nextera.

               Schedule 6.6 sets forth all of the issued and outstanding
membership interests of Nextera and Buyer on the date hereof and on the Closing
Date (assuming consummation of the transactions contemplated hereby, including,
in the case of Nextera, the issuance of Nextera Class A Units under the

outstanding options, warrants, rights, commitments, preemptive rights or
agreements of any kind for the issuance and sale of, or outstanding securities
convertible into, any additional membership interests of any class of Nextera or
Buyer. Schedule 6.6 sets forth a list of all agreements, instruments and
undertakings, if any, relating to the voting, transfer, registration, repurchase
or any similar right with respect to the issued and outstanding equity interests
of Nextera or Buyer. None of the equity interests of Nextera were issued in
violation of any federal or state law. All of the Nextera Class A Units to be
issued as consideration for the sale of the Assets will be duly issued under the
Nextera Operating Agreement free and clear of all liens or other encumbrances.

               6.7. Operating Agreements. The Nextera Operating Agreement

               6.8. Financial Statements.

               (a) Nextera has delivered to the Seller the following financial
statements, copies of which are attached hereto as Schedule 6.8: a consolidated
balance sheet of Nextera and its Subsidiaries and a consolidated statement of
profit and loss of Nextera as of December 31, 


<PAGE>   44
1997 as audited by Ernst & Young LLP (the "Audited Financial Statements"), an
unaudited balance sheet of Nextera and its Subsidiaries as of June 30, 1998 and
an unaudited statement of profit and loss of Nextera for the six months ended
June 30, 1998 (the "Interim Financial Statements") and together with the Audited
Financial Statements, the "Nextera Financial Statements"). The December 31, 1997
balance sheet is hereinafter referred to as the "Nextera Balance Sheet" and
December 31, 1997 is hereinafter referred to as the "Nextera Balance Sheet
Date." The Nextera Financial Statements have been prepared in accordance with
GAAP (subject to normal year-end adjustments in the case of the Interim
Financial Statements) applied consistently during the period covered thereby,
and said Audited Financial Statements present fairly in all material respects
the consolidated financial condition of Nextera at the date of said statements
and the consolidated results of its operations for the period covered thereby
and the Interim Financial Statements present fairly and completely in all
material respects the information purported to be shown thereon.

               (b) Except as set forth on Schedule 6.8, as of the date hereof,
Nextera and its Subsidiaries do not have any Liabilities of any nature, whether
accrued, absolute or contingent (including without limitation, Liabilities as
guarantor or otherwise with respect to obligations of others, or Liabilities for
any Tax due or then accrued or to become due or contingent or potential
Liabilities relating to activities of Nextera or any Subsidiary of Nextera or
the conduct of their respective business prior to the date hereof or the
Closing, as the case may be, regardless of whether claims in respect thereof had
been asserted as of such date), except Liabilities (i) stated or adequately
reserved against on the Nextera Balance Sheet or the notes thereto, (ii)
incurred or arising in the ordinary course of business of Nextera or any
Subsidiary of Nextera after the Nextera Balance Sheet Date, (iii) disclosed in
this Article VI or on the Nextera Disclosure Schedule or (iv) future performance
obligations under contracts and leases, none of which relates to any default,
breach of warranty, tort infringement, or violation of any Regulation or Court
Order or arose out of any action.

               (c) Nextera has delivered to Seller the following unaudited pro
forma financial statements, copies of which are attached hereto as Schedule 6.8:
a consolidated balance sheet of Nextera and its Subsidiaries as of June 30, 1998
and a consolidated statement of profit and loss of Nextera for the six months
ended June 30, 1998 (the "Pro Forma Statements"). The Pro Forma Statements have
been prepared giving effect to the consummation of each acquisition made by
Nextera subsequent to January 1, 1998 (including pursuant to this Agreement and
the acquisition of Sibson Canada). The Pro Forma Statements have been prepared
based on information Nextera believes to be reasonable as of the date of
delivery thereof, and present fairly in all material respects on a pro forma
basis the estimated financial position of Nextera as of June 30, 1998 and
results of operations for the six months then ended, assuming that the events
specified in the preceding sentence had actually occurred; provided, however,
that Nextera makes no representation with respect to the financial statements of
Seller or Sibson Canada reflected therein. The Pro Forma Statements are not
necessarily indicative of the financial position or results of operations that
would have been obtained had the pro forma events actually occurred and should
be read in conjunction with the Nextera Financial Statements provided to Seller.

               6.9. Taxes. Except as otherwise set forth on Schedule 6.9:

               (a) Each of Nextera and its Subsidiaries that are limited

               (d) There are no liens for Taxes upon any of the assets of

Subsidiary that is a limited liability company or, to the knowledge of Nextera,
any Subsidiary that is a corporation that has not been paid in full. There are
no outstanding waivers, extensions, or comparable consents regarding the

               (f) No audit or other proceeding by any federal, state, local or
foreign court, governmental, regulatory, administrative or similar authority is
presently pending with respect to any Taxes or Tax Return of Nextera, any
Subsidiary that is a limited liability company or, to the knowledge of Nextera,
any Subsidiary that is a corporation, and neither, Nextera, any Subsidiary that
is a limited liability company nor, to the knowledge of Nextera, any Subsidiary
that is a corporation has received written notice of any pending audits or
proceedings.

               (g) Nextera, each Subsidiary that is a limited liability company
and, to the knowledge of Nextera, each Subsidiary that is a corporation have
complied in all material respects with all applicable laws, rules and
regulations relating to the payment and withholding of Taxes (including, without
limitation, withholding of Taxes pursuant to Sections 1441, 1442, 1445 and 1446
of the Code or similar provisions under any applicable state and foreign laws)
and have, within the time and the manner prescribed by law, paid over to the

or assess any material amount of Taxes payable by Nextera, any Subsidiary that
is a limited liability company or, to the knowledge of Nextera, any Subsidiary
that is a corporation for any period ending on or prior to the Closing Date and
there are no facts of which Nextera is aware which would constitute grounds for
the assessment of any material amount of Taxes payable by Nextera, any
Subsidiary that is a limited liability company or, to the knowledge of Nextera,
any Subsidiary that is a corporation for any period ending on or prior to the
Closing Date.

               (k) No claim has been made by a taxing authority in a
jurisdiction where Nextera or any of its Subsidiaries does not file Tax Returns
such that it is or may be subject to taxation by that jurisdiction.

               (l) No issue has been raised by a federal, state, local or
foreign taxing authority in any examination relating to Nextera or any of its
Subsidiaries which, by application of the same or similar principles, could
reasonably be expected to result in a proposed deficiency for any subsequent
taxable period. Neither Nextera nor any of its Subsidiaries is subject to any
private letter ruling of the IRS or comparable rulings of other taxing
authorities.

               (m) Neither Nextera nor any of its Subsidiaries or any Person on

or any Subsidiary of Nextera not therefore a matter of public knowledge other
than as would not have a material adverse effect; or

               (k) agreement by Nextera to do any of the things described in the
preceding clauses (a) through (j) other than as expressly provided for herein.

               6.11. Insurance. Schedule 6.11 contains a complete and accurate
list of all policies or binders of fire, liability, title, worker's
compensation, product liability and other forms of insurance maintained by
Nextera or any Subsidiary of Nextera on its business, assets or employees. All
such insurance coverage applicable to Nextera or any Subsidiary of Nextera is in
full force and effect and provides coverage as may be required by applicable
Regulation and to the knowledge of Nextera by any and all contracts to which
Nextera or any Subsidiary of Nextera is a party. To the knowledge of Nextera,
there is no Default under any such coverage nor is there presently any failure
to give notice or present any claim under any such coverage in a due and 


<PAGE>   48
timely fashion, except for such Defaults and any such failure to give notice or
present any claim as would not, individually or in the aggregate, have a
material adverse effect. There are no outstanding unpaid premiums except in the
ordinary course of business and no notice of cancellation or nonrenewal of any
such coverage has been received. There are no provisions in such insurance
policies for retroactive or retrospective premium adjustments. All products
liability, general liability and workers' compensation insurance policies
maintained by Nextera or any Subsidiary of Nextera are presently occurrence
policies and not claims made policies. There are no outstanding performance
bonds covering or issued for the benefit of Nextera or any Subsidiary of
Nextera. To the knowledge of Nextera, no insurer has advised Nextera or any
Subsidiary of Nextera that it intends to reduce coverage, materially increase
premiums or fail to renew existing policy or binder. As of the Closing Date,
Buyer shall have insurance in place that is substantially similar to the type
and level of insurance maintained by Seller immediately prior to the Closing.

               6.12. Compliance with Laws. Nextera and each of its Subsidiaries
has been and are in substantial compliance with all Regulations and Court Orders
relating to the operations of Nextera and each of its Subsidiaries except in
each case for such non-compliance as would not, individually or in the
aggregate, have a material adverse effect. Within the last five years, none of
Nextera or its Subsidiaries has received any written notice to the effect that,
it is not in compliance with any such Regulations or Court Orders.

               6.13. Proprietary Rights.

               (a) Proprietary Rights. Schedule 6.13 lists: (i) for each
registered Trademark of Nextera or any Subsidiary of Nextera, the application
serial number or registration number, the class of goods covered and the
expiration date for each country in which a Trademark has been registered and
(ii) for each registered Copyright of Nextera or any Subsidiary of Nextera, the
number and date of filing for each country in which a Copyright has been filed.
Other than the items set forth on Schedule 6.13 and other than the unregistered
service/trade name "Nextera Enterprises" and variations thereof, there are no
Proprietary Rights used by Nextera or any Subsidiary of Nextera that are
material to the conduct of its business. Neither Nextera nor any Subsidiary of
Nextera has any patents or registered designs nor has it filed any patent
applications or registered design applications.

               (b) Royalties and Licenses. Except as set forth on Schedule 6.13
neither Nextera nor any Subsidiary of Nextera has any obligation to compensate
any person for the use of any such Proprietary Rights nor has Nextera or any
Subsidiary of Nextera granted to any person any license, option or other rights
to use in any manner any of such Proprietary Rights, whether requiring the
payment of royalties or not.

               (c) Ownership and Protection of Proprietary Rights. Except as set
forth on Schedule 6.13, Nextera and/or its Subsidiaries own or have a valid
right to use each of such Proprietary Rights. Except as set forth on Schedule
6.13, no other person (i) has notified Nextera or any Subsidiary of Nextera that
it is claiming any ownership of or right to use any such Proprietary Rights, or
(ii) to the knowledge of Seller, is infringing upon any such Proprietary Right
in any way. To the knowledge of Seller, except as set forth on Schedule 6.13,
use of such 


<PAGE>   49
Proprietary Rights by Nextera or any Subsidiary of Nextera does not and will not
conflict with, infringe upon or otherwise violate the valid rights of any third
party in or to such Proprietary Rights, and no Action has been instituted
against or notices received by Nextera or any Subsidiary of Nextera that are
presently outstanding alleging that use of the Proprietary Rights by Nextera or
any Subsidiary of Nextera infringes upon or otherwise violates any rights of a
third party in or to such Proprietary Rights.

               6.14. Indebtedness. Other than as set forth on Schedule 6.14,
neither Nextera nor its Subsidiaries has any indebtedness for borrowed money or
has guaranteed the obligations of any Person with respect to indebtedness for
borrowed money.

Contracts and Leases to be assumed by Buyer as listed on Schedule 7.1; provided,
however, that to the extent Buyer fails to cooperate (i) by providing on a
timely basis any financial or similar information reasonably requested by the
party whose consent is sought, including, without limitation, any pro forma
financial statements with respect to Buyer reflecting the consummation of the
transactions contemplated hereby, or (ii) executing and delivering any
assumption agreement or similar instrument requested by any lessor or sublessor
and which is reasonably acceptable to Buyer in connection with the obtaining of
any consent with respect to a Contract or Facility Lease listed on Schedule 7.1,
Seller shall not be required to obtain said consent hereunder and the obtaining
of said consent shall no longer be deemed a condition to Closing under Article
IX hereof; provided, further that no party shall be required to make any
payments, commence litigation or agree to modifications of the terms thereof in
order (i) to obtain any such waivers, consents or approvals, (ii) to obtain all
necessary Permits as are required to be obtained under any Regulations, (iii) to
give all notices to, and make all registrations and filings with third parties,
including without limitation submissions of information requested by

               Between the date of this Agreement and the Closing, Nextera shall
provide Seller with prior written notice of (a) any material actions,

Partner, Limited Partner, nor any of their officers, directors, agents, or
employees or Representatives will, directly or indirectly, solicit, encourage,

entertain or enter into any agreement or transaction with, any person, other
than Nextera, relating to the possible acquisition of the equity of Seller or

business of Seller consistent with the terms of this Agreement. If such a
proposal is 


<PAGE>   52
received, Seller will promptly notify Nextera of the terms of such proposal and
the identity of the party making the proposal.

               7.4. Notification of Certain Matters.

               (a) From the date hereof through the Closing, Seller, General
Partner, Limited Partner and the Shareholders on the one hand, and Buyer and
Nextera on the other hand, shall give prompt notice to the other of (i) the
occurrence, or failure to occur, of any event which occurrence or failure would
be likely to cause any representation or warranty made by such person and
contained in this Agreement or in any exhibit or schedule hereto to be untrue or
inaccurate in any respect and (ii) any failure of such party, or any of its
respective affiliates or Representatives, to comply with or satisfy any
covenant, condition or agreement to be complied with or satisfied by it under
this Agreement or any exhibit or schedule hereto; provided, however, that such
disclosure shall not be deemed to cure any breach of a representation, warranty,
covenant or agreement or to satisfy any condition except as otherwise provided
in Section 7.4(b) hereof. The Seller shall promptly notify Nextera of any
Default, the threat or commencement of any Action, or any development that
occurs before the Closing that could in any way materially affect Seller, the
Assets or the Business. The Buyer and Nextera shall promptly notify the Selling
Parties of any default, the threat or commencement of any action, or any
development that occurs before the Closing that could in any way materially
affect the Buyer or Nextera, individually, or their respective businesses and
operations.

               (b) Anything in Section 7.4(a) to the contrary notwithstanding,
if any event not expressly contemplated by this Agreement occurs at any time
between the date hereof and the Closing Date that would result in any
representation or warranty made by the Selling Parties, on the one hand, and
Buyer and Nextera, on the other hand, not being true in any material respect on
the Closing Date, such parties shall promptly give written notice of such event
to such other parties. Following receipt of such notice, the parties receiving
notice shall have no obligation to consummate the transactions contemplated
hereby and the Selling Parties, on the one hand, or Buyer and Nextera, on the
other hand, may terminate this Agreement pursuant to Article XIII hereof;
provided, however, that if such parties consummate the transactions contemplated
hereby, such parties shall not have any indemnification rights hereunder
relating to or arising out of, the subject matter of the event described in any
written notice validly given pursuant to this Section 7.4(b) and; provided,
further, that the giving of any notice by a party pursuant to this Section
7.4(b) shall not relieve such party of any liability for breach of any covenant
hereunder or the failure of any representation or warranty of such party
hereunder to be true and correct as of the date hereof.

               7.5. Employee Matters.

               (a) In addition to the Employment Agreements described in Section
9.13, Buyer shall extend offers of employment to all of the employees of Seller
and its Subsidiaries (such employees are hereinafter referred to as the "Rehired
Employees") effective as of the Closing, which offers shall be on terms and
conditions substantially similar to the current terms and conditions of
employment by Seller and its Subsidiaries. Seller shall cooperate with and use


<PAGE>   53
its commercially reasonable efforts to assist Buyer in its efforts to secure
satisfactory employment arrangements with the employees of Seller.

               (b) Effective as of the Closing Date, Buyer shall adopt, assume
sponsorship of and substitute itself as employer under each of the Seller
Employee Programs listed on Schedule 4.23. Seller shall take all actions within
its authority to enable and use its best efforts to assist Buyer in adopting and
assuming such programs, including obtaining resignations effective as of the
Closing Date of any and all fiduciaries (including trustees, committee members
and plan administrators) with respect to such programs whose resignation is
requested by Buyer. In connection with the assumption of the Seller Employee
Programs, Buyer shall assume all liabilities and obligations relating thereto,
including those incurred prior to, on or after the Closing Date with respect to
all participants thereunder.

               (c) Buyer agrees that, with respect to all of its employee
benefit programs and arrangements covering or otherwise benefiting any of the
Rehired Employees on or after the Closing Date, service with Seller and its
affiliates shall be counted for purposes of determining any period of
eligibility to participate or to vest in benefits to the same extent such
service was counted under the Seller Employee Programs.

               (d) Subject to Section 10.1, Seller shall use its best efforts to
cause to be transferred to the Buyer all life and other insurance policies used
in connection with the Seller Employee Programs.

               (e) Except to the extent required by law, Seller shall not pay
Rehired Employees their accrued and unused vacation, and Buyer shall provide,
without duplication of benefits, all Rehired Employees with vacation time rather
than cash in lieu of vacation time for all vacation earned and unpaid through
the Closing Date.

               (f) Buyer shall provide a medical plan as of the Closing Date so
as to ensure uninterrupted coverage of all Rehired Employees. Such medical plan
shall grant credit for amounts paid by employees during the applicable plan year
beginning prior to the Closing Date, shall not exclude pre-existing conditions
and shall provide for medical benefits substantially consistent with the
Seller's (and its Subsidiaries') medical plan in effect prior to the Closing
Date.

               (g) From and after the Closing Date until December 31, 1999,
Buyer shall, and shall cause its Subsidiaries, to provide employee benefits and
compensation to the Rehired Employees which are substantially similar to those
provided by Seller and its Subsidiaries immediately prior to the Closing Date,
provided, however, that at any time (i) Nextera may in its sole discretion cause
Buyer or Buyer's Subsidiaries (A) to modify or terminate any employee benefits
provided to such Rehired Employees as Nextera deems necessary to provide that
any employee benefit plan and related trust intended to be qualified and exempt
under Code Sections 401(a) and 501(a), respectively, shall be so qualified and
exempt, or (B) to otherwise comply with the applicable requirements of ERISA (or
other applicable law) and (ii) the Leadership Council (as defined in the Buyer
Operating Agreement) may terminate such employee benefits in its discretion. In
the event that any employee benefits are terminated or materially reduced
pursuant to subsection (g)(i), Buyer (or a Subsidiary thereof) shall provide
each applicable Rehired 


<PAGE>   54
Employee with other benefits or one or more cash payments which in the aggregate
on an after-tax basis are equal to the value of such terminated or
materially-reduced benefits through the earlier of December 31, 1999 or the date
of the Rehired Employee's termination of employment.

               (h) Except as provided in the Employment Agreements described in
Section 9.13, nothing contained in this Agreement shall confer upon any Rehired
Employee any right with respect to continuance of employment by Buyer, nor shall
anything herein interfere with the right of Buyer to terminate the employment of
any of the Rehired Employees at any time, with or without cause, or restrict
Buyer in the exercise of its independent business judgment in modifying any of
the terms and conditions of the employment of the Rehired Employees.

               (i) Except as provided in the Employment Agreements described in
Section 9.13, no provision of this Agreement shall create any third party
beneficiary rights in any Rehired Employee, any beneficiary or dependents
thereof, or any collective bargaining representative thereof, with respect to
the compensation, terms and conditions of employment and benefits that may be
provided to any Rehired Employee by Buyer or under any benefit plan which Buyer
may maintain.

               (j) Seller shall not, directly or indirectly, hire or offer
employment to or seek to hire or offer employment to any employee of Seller
whose employment is continued by Buyer after the Closing Date or any employee of
Buyer or any successor or affiliate of Buyer which is engaged in the Business,
unless Buyer first terminates the employment of such employee or gives its
written consent to such employment or offer of employment.

               7.6. Option Pool. At the Closing, Nextera agrees to grant to the
Rehired Employees and the new hires of Buyer who are involved in the Business
options under the Amended and Restated Equity Participation Plan effective as of
July 28, 1998 (the "Equity Participation Plan"), a true and correct copy of
which is attached hereto as Exhibit P and in the forms of related agreements
attached hereto as Exhibit Q-1 for those Rehired Employees who are also
Principals and Exhibit Q-2 for the those Rehired Employees or new hires who are
not also Principals, which grants shall consist of an aggregate pool of options
to purchase 815,000 Nextera Class A Units to be distributed and allocated as set
forth in a letter of even date herewith from Seller to Buyer and Nextera which
letter makes specific reference to this Section 7.6. Such options shall have an
exercise price of $7.50 per share and shall vest at the rate of twenty-five
percent (25%) per year over four (4) years. Buyer and Nextera also agree to make
available an additional pool of options to purchase 100,000 Nextera Class A
Units for hiring purposes and performance recognition in calendar year 1998
subject to Nextera's review and approval and with such terms and conditions as
may be determined by Nextera, of which options to purchase 30,000 Nextera Class
A Units have been allocated as set forth on in the letter referred to in the
preceding sentence.

               Nextera has duly adopted the Equity Participation Plan in the
form attached as Exhibit P and form of related agreement in the forms attached
as Exhibit Q-1 and Exhibit Q-2 hereto. The Shareholders acknowledge that (a) the
terms of the options are governed by such Equity Participation Plan attached as
Exhibit P and related agreements in the forms attached as Exhibit Q-1 and
Exhibit Q-2, and (b) the tax consequences of the options are materially
different 


<PAGE>   55
in a limited liability company as compared to a corporate structure, and the
Shareholders have had the opportunity to consult their own tax advisors of such
tax consequences.

               7.7. Additional Units. The Employment Agreements referred to in
Section 9.13 (other than those in the form of Exhibit J-5) shall provide for the
sale by Nextera of Nextera Class A Units to the individuals whose names are set
forth in a letter of even date herewith from Seller to Buyer and Nextera which
letter makes specific reference to this Section 7.7.

               7.8. Conduct of the Business Following the Closing.

               (a) Buyer and Nextera agree to maintain the consulting service
offerings of Seller in substantially the same form as such service offerings
existed immediately prior to the Closing; provided, however, that Buyer and
Nextera (or the entity controlled by Nextera which provides such service
offerings) (i) may make available additional service offerings and (ii) may
eliminate existing service offerings if the gross revenues and/or net profits
derived from such offerings are determined by Nextera to be inadequate to
maintain such service offerings.

               (b) Buyer and Nextera hereby confirm that as of the date hereof
they intend (i) to use the "Sibson & Company, L.L.C., a Nextera Company" name in
its worldwide operations, (ii) to cause Buyer (or some other entity controlled
by Nextera) to conduct the Business for the foreseeable future and (iii) to
cause Buyer or such other entity that conducts the Business to lead human
capital consulting for Nextera and its Subsidiaries. The parties acknowledge
that the intention of Buyer and Nextera with respect to this Section 7.8(b) is
not a binding commitment on the part of Buyer or Nextera.

               7.9. Permitted Distribution. Prior to the Closing, Seller shall
be permitted to accrue and declare a distribution (the "Permitted Distribution")
to General Partner and Limited Partner provided that at the Closing, taking into
account the Permitted Distribution, Seller shall have an amount of working
capital greater than or equal to the Minimum Working Capital. Effective as of
the Closing, Buyer hereby agrees to assume the liability to pay the Permitted
Distribution and shall pay the Permitted Distribution within 15 days after
resolution of the Working Capital Adjustment under Section 2.5 provided that at
such time Buyer has sufficient cash or availability under its revolving credit
facility to make the Permitted Distribution; provided further, however, that in
no event shall Buyer pay the Permitted Distribution later than December 31,
1998. In the event that the Permitted Distribution is to be paid after the
Incorporation Transaction (as defined in the Exchange Agreement), Buyer shall
make such payment to the Shareholder Representative for distribution to the
Shareholders.

               7.10. Preservation of Confidentiality. In connection with the
negotiation of this Agreement and the preparation for the consummation of the
transactions contemplated hereby, the parties acknowledge that each has had
access to confidential information relating to each other, including technical

improvements, business plans, trade secrets, scientific or statistical data,
diagrams, drawings, specifications or other proprietary information relating
thereto, together with all analyses, compilations, studies or other documents,
records or data prepared by Seller, General Partner, Limited Partner, the
Shareholders, Buyer, Nextera or their respective Representatives which

("Confidential Information"). Prior to the date of the Closing, each of the
parties shall treat all Confidential Information as confidential, preserve the
confidentiality thereof and not disclose any Confidential Information, except to
their Representatives and affiliates who need to know such Confidential
Information in connection with the transactions contemplated hereby. The parties
shall use all reasonable efforts to cause their Representatives to treat all
Confidential Information as confidential, preserve the confidentiality thereof
and not disclose any Confidential Information. Each party shall be responsible
for any breach of this Agreement by any of its Representatives.

               7.11. No Distribution of Nextera Class A Units. Except following
a breach by Nextera of its obligation to effect the Incorporation Transaction
(as defined in the Exchange Agreement), Seller, General Partner and Limited
Partner agree to retain the Nextera Class A Units and to not distribute such
units to the Shareholders, provided that Seller may distribute the Nextera Class
A Units it receives pursuant to this Agreement to General Partner and Limited
Partner. It being understood that the capital stock of General Partner and
Limited Partner will be exchanged pursuant to the Exchange Agreement.

               7.12. Buyer Efforts on Financing and Qualifications. Buyer agrees
to use commercially reasonable efforts to (i) consummate the third party
financing to fund the Purchase Price pursuant to the commitment letter attached
hereto Exhibit O, (ii) qualify itself to do business in each jurisdiction in

Newco (as defined in the Exchange Agreement) or other similar team comprised of
representatives of Nextera's Subsidiaries or the Subsidiaries of Newco, subject
to the approval of such designees by Nextera (which approval shall not be
unreasonably withheld). The Leadership Council of Buyer shall have the right to
remove and designate replacements for such designees to the Senior Leadership
Team of Nextera and/or Newco or such other similar teams subject to Nextera's
approval (which approval shall not be unreasonably withheld).

reasonable business purpose. The party requesting any such Books and Records,
information or employees shall bear all of the out-of-pocket costs and expenses

such Books and Records, information or employees.

               (b) Cooperation and Records Retention. Seller, General Partner,

authority or judicial or administrative proceedings relating to Liability for
Taxes, (ii) each provide the others with any records or other information that
may be relevant to such Tax Return, audit or examination, proceeding or
determination subject to the last sentence of this subsection (b), and (iii)
each provide the others with any final determination of any such audit or
examination, proceeding, or determination that affects any amount required to be
shown on any Tax Return of the other for any period. Without limiting the

<PAGE>   63
each retain, until the applicable statutes of limitations (including any
extensions) have expired, copies of all Tax Returns, supporting work schedules,
and other records or information that may be relevant to such Tax Returns for
all tax periods or portions thereof ending on or before the Closing Date and

calendar year, and taxes withheld therefrom, and Seller shall be relieved of the
responsibility to do so.

shall pay promptly when due all of the debts and Liabilities of Seller for
Taxes; provided, however, this covenant shall not apply to that portion (or all)
of any Tax that Seller is contesting in good faith. Following the Closing Date,
Buyer shall pay promptly when due all of the Assumed Liabilities; provided,
however, this covenant shall not apply to that portion (or all) of any Liability
that Buyer is contesting in good faith.

               11.3. Survival of Representations, Etc. Each of the
representations, warranties, agreements, covenants and obligations herein are
material, shall be deemed to have been relied upon by the other party and shall
survive the Closing regardless of any investigation and shall not merge in the

such representations and warranties shall expire on the same dates as and to the
extent that the rights to indemnification with respect thereto under Article XII
shall expire.

limitations set forth in this Section 12.4.

claims for indemnification hereunder by giving written notice thereof to the
indemnifying party promptly on discovery and in any event within the period in
which indemnification claims can be made hereunder. If indemnification is sought
for a claim or liability asserted by a third party, the indemnified party shall
also give written notice thereof to the indemnifying party promptly after it
receives notice of the claim or liability being asserted, but the failure to do
so shall not relieve the indemnifying party from any liability except to the
extent that it is prejudiced by the failure or delay in giving such notice. Such
notice shall summarize the basis for the claim for indemnification and any claim
or liability being asserted by a third party. Within 20 days after receiving
such notice the indemnifying party shall give written notice to the indemnified
party stating whether it disputes the claim for indemnification and whether it
will defend against any third party claim or liability at its own cost and
expense. If the indemnifying party fails to give notice that it disputes an
indemnification claim within 20 days after receipt of notice thereof, it shall
be deemed to have accepted and agreed to the claim, which shall become
immediately due and payable. The indemnifying party shall be entitled to direct
the defense against a third party claim or liability with counsel selected by it
(subject to the consent of the indemnified party, which consent shall not be
unreasonably withheld) as long as the indemnifying party is conducting a good
faith and diligent defense and to compromise or settle it with consent of the
indemnified party, which consent shall not be unreasonably withheld. The
indemnified party shall at all times have the right to fully participate at its
own expense in the defense of a third party claim or liability, directly or
through counsel; provided, however, that if the named parties to the action or
proceeding include both the indemnifying party and the indemnified party and the
indemnified party is advised that representation of both parties by the same
counsel would be inappropriate under applicable standards of professional
conduct, the indemnified party may engage separate counsel at the expense of the
indemnifying party. If no such notice of intent to dispute and defend a third
party claim or liability is given by the indemnifying party, or if such good
faith and diligent defense is not being or ceases to be conducted by the
indemnifying party, the indemnified party shall have the right, at the expense
of the indemnifying party, to undertake the defense of such claim or liability
(with counsel selected by the indemnified party), and to compromise or settle
it, with consent of the indemnifying party, which consent shall not be
unreasonably withheld. If the third party claim or liability is one that by its
nature cannot be defended solely by the indemnifying party, then the indemnified
party shall make available such information and assistance as the indemnifying
party may reasonably request and shall cooperate with the indemnifying party in
such defense, at the expense of the indemnifying party.

               12.6. Satisfaction of Selling Party Indemnification Obligations.
Nextera shall bring and control all indemnification claims hereunder and under
the Exchange Agreement on behalf of the Buyer Indemnified Parties, including
without limitation Buyer. In order to satisfy the indemnification obligations of
the Selling Parties hereunder and under the Exchange Agreement, 


<PAGE>   67
Nextera shall proceed first directly against the Escrow Deposit as further set
forth and defined in the Escrow Agreement and then may proceed directly against
the Selling Parties subject to the limitations set forth herein. Nextera may
proceed against the Selling Party of its choosing and may proceed directly
against any Shareholder without proceeding against Seller, General Partner
and/or Limited Partner. Any Shareholder called upon to satisfy indemnification
obligations in connection with this Agreement may not seek any right of
contribution against (a) General Partner or Limited Partner following completion
of the Incorporation Transaction (as defined in the Exchange Agreement) or (b)
Seller following completion of the Incorporation Transaction unless Seller has
been converted to a limited liability company the membership interests of which
are not owned by General Partner or Limited Partner.

               12.7. Use of Nextera Class A Units. To the extent indemnification
claims exceed the Escrow Deposit (as defined in the Escrow Agreement), the
parties may, at their option, elect to satisfy any indemnification claims under
this Agreement by delivering Nextera Class A Units issued pursuant to Section
2.4 or any securities into or for which they may be converted or exchanged. To
the extent that Nextera Class A Units (or such other securities) are used to
satisfy indemnification obligations under this Agreement, such units shall be
valued in accordance with the terms of the Escrow Agreement. No statement of
value in this Agreement shall affect such valuation under the Escrow Agreement.

               12.8. Bulk Sales. Buyer hereby waives any requirements for
compliance with the procedures of the "Bulk Sales Act" or similar laws of any or
all of the states in which the Assets are situated or of any other state which
may be asserted to be applicable to the transactions contemplated hereby and
agrees that the Selling Parties shall have no indemnity obligations under
Article XII hereof arising solely out of or resulting solely from the failure of
Seller or Buyer to comply with any such laws.

               12.9. Exclusive Remedy. Other than Fraud Claims and claims
pursuant to Section 12.3(a), the foregoing indemnification provisions in this
Article XII shall be the exclusive remedy for any breach of the representations
and warranties of the Selling Parties in Articles IV and V and of Buyer and
Nextera in Article VI above.

                                  ARTICLE XIII.

                   TERMINATION OF AGREEMENT; RIGHTS TO PROCEED

               13.1. Termination. At any time prior to the Closing, this
Agreement may be terminated as follows:

                      (i) by mutual written consent of Nextera and the
Shareholder Representative;

                      (ii) by Buyer or Nextera, pursuant to written notice to
Seller, if any of the conditions set forth in Article IX of this Agreement have
not been satisfied at or prior to the Closing, or if it has become reasonably
and objectively certain that any of such conditions, other than a condition
within the control of the Selling Parties, will not be satisfied at or prior to


<PAGE>   68
the Closing, such written notice to set forth such conditions which have not
been or will not be so satisfied;

                      (iii) by the Seller, pursuant to written notice to Buyer
and Nextera, if any of the conditions set forth in Article VIII of this
Agreement have not been satisfied at or prior to the Closing, or if it has
become reasonably and objectively certain that any of such conditions, other
than a condition within the control of Buyer and Nextera, will not be satisfied
at or prior to the Closing, such written notice to set forth such conditions
which have not been or will not be so satisfied;

                      (iv) by the Selling Parties, on the one hand, or by
Nextera and Buyer, on the other, pursuant to Section 7.4(b); and

                      (v) by Nextera or the Shareholder Representative if the
Closing shall not have occurred on or before September 30, 1998.

               13.2. Effect of Termination. All obligations of the parties
hereunder shall cease upon any termination pursuant to Section 13.1, provided,
however, that the provisions of Section 7.10, Article XIII, Section 14.1 and
Section 14.9 hereof shall survive any termination of this Agreement. No
termination shall relieve any party of any liability for breach of this
Agreement prior to termination except as otherwise provided herein.

                                  ARTICLE XIV.

                                  MISCELLANEOUS

               14.1. Fees and Expenses. Except as otherwise specified in this
Agreement and the Buyer Operating Agreement, each party hereto shall pay its own
legal, accounting, out-of-pocket and other expenses incident to this Agreement
and to any action taken by such party in preparation for carrying this Agreement
into effect. With respect to any payment by Seller for fees and expenses
incurred by the Selling Parties, such payment shall reduce the amount of Closing
Working Capital for purposes of Section 2.5 hereto. Notwithstanding the
foregoing, in the event the transaction does not close solely as a result of
Nextera's failure to obtain third party financing for the Purchase Price,
Nextera shall reimburse Seller for its actual out-of-pocket expenses incurred in
connection herewith, up to a maximum of $250,000, upon the submission of
reasonably detailed invoices for such expenses.

               14.2. Governing Law. This Agreement shall be construed under and
governed by the internal laws of the State of New York without regard to its
conflict of laws provisions.

               14.3. Notices. Any notice, request, demand or other communication
required or permitted hereunder shall be in writing and shall be deemed to have
been given if delivered or sent by facsimile transmission, upon receipt, or if
sent by registered or certified mail, upon the sooner of the date on which
receipt is acknowledged or the expiration of three days after deposit in United
States post office facilities properly addressed with postage prepaid. All

Any notice given hereunder may be given on behalf of any party by his counsel or
other authorized representatives.

               14.4. Entire Agreement. This Agreement, including the Escrow
Agreement, Employment Agreements, Exchange Agreement and schedules and exhibits
hereto and thereto, is the entire agreement of the parties with respect to its
subject matter, and supersedes all previous written or oral negotiations,
commitments and writings. No promises, representations, understandings,
warranties and agreements have been made by any of the parties hereto except as
referred to herein or in such schedules and exhibits; and all inducements to the
making of this Agreement relied upon by either party hereto have been expressed
herein or in such schedules or exhibits.

               14.5. Assignability; Binding Effect. This Agreement shall only be
assignable by Buyer or Nextera to an entity controlling, controlled by or under
common control with Buyer or Nextera upon written notice to Seller; provided,
however, that Buyer and Nextera shall remain liable for all obligations
hereunder to the extent such obligations are not satisfied by the transferee.
This Agreement may not be assigned by Seller without the prior written consent
of Nextera. This Agreement shall be binding upon and enforceable by, and shall
inure to the benefit of, the parties hereto and their respective successors and
permitted assigns. Assignment of this Agreement by any party shall not relieve
such party from its obligations hereunder.

               14.6. Captions and Gender. The captions in this Agreement are for
convenience only and shall not affect the construction or interpretation of any
term or provision hereof. The use in this Agreement of the masculine pronoun in
reference to a party hereto shall be deemed to include the feminine or neuter,
as the context may require.

               14.7. Execution in Counterparts. For the convenience of the
parties and to facilitate execution, this Agreement may be executed in two or
more counterparts, each of which shall be deemed an original, but all of which
shall constitute one and the same document.

               14.8. Amendments. This Agreement may not be amended or modified,
nor may compliance with any condition or covenant set forth herein be waived,
except by a writing duly and validly executed by each party hereto, or in the
case of a waiver, the party waiving compliance; provided that the Shareholder
Representative (as defined below) may consent to any such amendment or
modification or waiver on behalf of the Shareholders; provided further that the
Shareholder Representative may not enter into any such amendment or modification
or waive any condition or covenant that materially and adversely affects any
Shareholder differently than all other Shareholders affected thereby without the
consent of such Shareholder. Each of the Shareholders hereby designate the
Seller and, upon conversion of Seller to a limited liability company as provided
in Section 4.4 of the Exchange Agreement, such limited liability company (in
each instance and in such capacity, the "Shareholder Representative") to act for
and represent them in those matters with respect to which this Agreement
specifies that the Shareholder Representative shall so act, including, without
limitation, entering into any amendment to this Agreement, and Seller, on behalf
of itself and its successors and assigns, hereby accepts such designation.
Anything herein to the contrary notwithstanding, any amendment, modification or
waiver to be given by the Shareholders may be given by the Shareholder
Representative.

               14.9. Publicity and Disclosures. No press releases or public
disclosure (other than disclosure to Seller's clients regarding the closing of
this transaction as is reasonably deemed necessary by the parties to promote
Buyer's provision of service to such clients and in connection with the transfer
of Assets as contemplated hereunder), either written or oral, of the
transactions contemplated by this Agreement, shall be made by a party to this
Agreement without the prior knowledge and written consent of Nextera and Seller.

               14.10. Specific Performance. The parties agree that it would be
difficult to measure damages which might result from a breach of this Agreement
by the Selling Parties and that money damages would be an inadequate remedy for
such a breach. Accordingly, if there is a breach or proposed breach of any
provision of this Agreement by any Selling Party, and Buyer or 


<PAGE>   74
Nextera do not elect to terminate under Article XIII, Buyer or Nextera shall be
entitled, in addition to any other remedies which it may have, to an injunction
or other appropriate equitable relief to restrain such breach without having to
show or prove actual damage to Buyer or Nextera.

               The parties agree that it would be difficult to measure damages

that money damages would be an inadequate remedy for such a breach. Accordingly,
if there is a breach or proposed breach of any provision of this Agreement by

XIII, Selling Parties shall be entitled, in addition to any other remedies which
they may have, to an injunction or other appropriate equitable relief to
restrain such breach without having to show or prove actual damage to Selling
Parties.

                                ESCROW AGREEMENT

               This Escrow Agreement (the "Agreement") is entered into as of
August 31, 1998 by and among SC/NE, LLC, a Delaware limited liability company
("Buyer"), Nextera Enterprises, L.L.C., a Delaware limited liability company and
the controlling member of Buyer ("Nextera"), Sibson & Company, L.P., a Delaware
limited partnership ("Seller"), Sibson & Company, Inc., a Delaware corporation
("General Partner"), SC2, Inc., a Delaware corporation ("Limited Partner"), the
holders of capital stock of the General Partner and the Limited Partner (the
"Shareholders"), and Chase Manhattan Trust Company, National Association, as
escrow agent (the "Escrow Agent").

               WHEREAS, pursuant to an Asset Purchase Agreement (the "Purchase
Agreement") dated as of the date hereof, by and among Buyer, Nextera, Seller,
General Partner, Limited Partner and the Shareholders, Buyer is purchasing
certain assets and assuming certain liabilities from Seller;

               WHEREAS, Seller, General Partner, Limited Partner and the
Shareholders have agreed to indemnify Buyer and Nextera against certain breaches
of the representations, warranties and covenants made by Seller, General
Partner, Limited Partner and the Shareholders in the Purchase Agreement and
against certain other matters as specified in Article XII of the Purchase
Agreement; and

               WHEREAS, to secure payment of the Shareholders' indemnification
obligations, 784,548 Class A Common Units of Nextera (the "Escrow Units" and
together with additions to or earnings on the same, the "Escrow Deposit") are
being deposited, pursuant to Section 2.4 of the Purchase Agreement, in escrow to
be held as hereinafter provided.

               NOW, THEREFORE, in consideration of the foregoing and the mutual
promises of the parties herein contained, and other good and valuable
consideration, receipt and sufficiency of which is hereby acknowledged, the
parties hereto agree as follows:

               1. Establishment of Escrow: Investment.

               (a) Buyer and Nextera have herewith deposited the Escrow Units
with the Escrow Agent contemporaneously herewith. The Escrow Units have been
issued in the name of Seller, and shall be accompanied by stock powers or
similar instruments duly signed in blank by Seller. Seller may transfer and
assign its right to the Escrow Units to General Partner and Limited Partner by
providing written notice to the Escrow Agent and Nextera and by furnishing to
Nextera such documents as may be required to effect such transfer as set forth
in the last sentence of Section 6 hereof. The Escrow Deposit shall be held in
escrow in an account designated as the Sibson & Company Escrow Account or an
account having such other similar designation, subject to the terms and
conditions set forth herein. The Escrow Agent shall invest all cash, if any,
held as part of the Escrow Deposit only in such specific investments as Nextera
and the Escrow

Representative (as hereinafter defined) shall from time to time jointly direct
in writing to the Escrow Agent; provided, however, that such investments shall
be limited to:

                  (1)      time and demand deposits, certificates of deposit and
                           acceptances, maturing within ninety (90) days from
                           the date of acquisition thereof, issued by state and
                           national banks located in the United States of
                           America, including the Escrow Agent or any of its
                           affiliates, and having capital, surplus and profits
                           aggregating at least one hundred million dollars
                           ($100,000,000);

                  (2)      securities or other obligations of, or guaranteed by,
                           the United States of America or any agency thereof
                           having maturities of not greater than one (1) year;

                  (3)      commercial paper, maturing within ninety (90) days
                           from the date of acquisition thereof, rated A-1 or
                           P-1 by Standard & Poor's or Moody's Investors
                           Service;

                  (4)      repurchase agreements fully collateralized by
                           obligations described in clauses 1(a)(1), 1(a)(2) or
                           1(a)(3) hereof;

                  (5)      shares of investment companies registered under the
                           Investment Company Act of 1940 which invest in any
                           obligation described herein, or shares of the Chase
                           Vistasm Money Market Mutual Funds or any other mutual
                           fund for which the Escrow Agent or an affiliate of
                           the Escrow Agent serves as investment manager,
                           administrator, shareholder servicing agent, and/or
                           custodian or subcustodian, notwithstanding that (i)
                           the Escrow Agent or an affiliate of the Escrow Agent
                           receives fees from such funds for services rendered
                           or (ii) services performed for such funds and
                           pursuant to this Agreement may at times duplicate
                           those provided to such funds by the Escrow Agent or
                           its affiliates.

               Until further written notice, cash in the Escrow Deposit shall be
invested in Chase Vistasm Prime Money Market Fund. Unless otherwise directed in
writing by the Escrow Representative and Nextera, the Escrow Agent shall not
invest all or any portion of the Escrow Deposit in any investment if the
maturity date of such investment is later than the Termination Date (as defined
below).

               (b) Seller, General Partner, Limited Partner and the Shareholders
(collectively, the "Selling Parties" and each, individually, a "Selling Party")
hereby appoint Seller and, upon conversion of Seller to a limited liability
company, such limited liability company, to serve as the exclusive
representative of the Selling Parties with respect to this Agreement (the
"Escrow Representative"). and Seller, on behalf of itself and its successors and
assigns, hereby accepts such appointment. If, for any reason, the Escrow
Representative shall be either unable or unwilling to serve, a successor Escrow
Representative shall be appointed by written consent of the Shareholders and all
references to the Escrow Representative shall be deemed to include such






                                       2
<PAGE>   3

successor. Each Selling Party whose signature appears below expressly agrees
that this Agreement may be amended or modified, and compliance with any
condition or covenant may be waived without the consent of, or execution thereof
by, such Selling Party if the Escrow Representative agrees to such amendment or
modification or grants such waiver, in each case by a writing duly and validly
executed by the Escrow Representative as provided in Section 13; provided,
however, that the Escrow Representative will not enter into any such amendment
or modification or waive any condition or covenant that materially and adversely
affects any Shareholder differently than all other Shareholders affected thereby
without the consent of such Shareholder.

               2. Amounts Earned on Escrow Deposit: Tax Matters. All amounts
earned, paid or distributed with respect to the Escrow Deposit, if any, (whether
interest, dividends, distributions from Nextera with respect to the Escrow Units
or otherwise) shall become a part of the Escrow Deposit, shall be held hereunder
upon the same terms as the original Escrow Deposit and shall be distributed
together with the underlying portion of the original Escrow Deposit pursuant to
the terms of this Agreement. The parties agree that, prior to the consummation
of the transactions contemplated by the Exchange Agreement (as defined in
Section 5 below), the Partnership or the General Partner and the Limited
Partner, as the case may be, will include all amounts earned on the Escrow
Deposit (or allocated or distributed with respect thereto) in their gross income
for federal, state and local income tax (collectively, "income tax") purposes
and pay any income tax resulting therefrom. The parties agree that, after the
consummation of the transactions contemplated by the Exchange Agreement, the
Shareholders shall include all amounts earned on the Escrow Deposit in their
gross income for income tax purposes and pay any income tax resulting therefrom,
pro rata in accordance with their combined ownership percentage as set forth on
Exhibit A.

               3. Claims Against Escrow Deposit.

               (a) At any time or times prior to the Termination Date (as
hereinafter defined), Nextera, or any successor of Nextera, may make claims
against the Escrow Deposit for indemnification pursuant to and in accordance
with Article XII of the Purchase Agreement or Article VI of the Exchange
Agreement. Nextera shall notify the Escrow Representative and the Escrow Agent
in writing promptly upon determination to make a claim and in any event prior to
the expiration of this Agreement of each such claim, including a summary of the
amount of and bases for such claim. If the Escrow Representative shall dispute
such claim, the Escrow Representative shall give written notice thereof to
Nextera and to the Escrow Agent within thirty (30) days after receipt of notice
of Nextera's claim, in which case the Escrow Agent shall continue to hold the
Escrow Deposit in accordance with the terms of this Agreement; otherwise, such
claim shall be deemed to have been acknowledged to be payable out of the Escrow
Deposit in the full amount thereof and the Escrow Agent shall use its best
efforts to pay such claim to Nextera within three (3) business days after
expiration of said thirty (30) day period or as soon thereafter as possible
following the determination of the fair market value of the Escrow Units
pursuant to Section 3(b)(ii) below. If the amount of the claim exceeds the value
of the Escrow Deposit, the Escrow Agent shall have no liability or
responsibility for any deficiency.

               (b) The Escrow Agent shall follow the procedure below in making
any payment in satisfaction of a claim against the Escrow Deposit:

                   (i) The Escrow Agent shall make such payment first from cash
additions to or earnings on the Escrow Units, if any, until all cash in the
Escrow Deposit has been exhausted.

                   (ii) To the extent that any claim exceeds the amount of cash
in the Escrow Deposit, the Escrow Agent shall make payment from the Escrow Units
in such number of Escrow Units (computed to the nearest whole unit) having a
value equal to the value of the claim not satisfied by cash payment. Any payment
of Escrow Units by the Escrow Agent to Nextera shall be treated as an adjustment
to the number of Class A Common Units of Nextera received as consideration under
the Purchase Agreement by Seller or, following consummation of the transactions
contemplated by the Exchange Agreement as an adjustment to the consideration
received by the Shareholders pursuant to the Exchange Agreement, as the case may
be. The value of an Escrow Unit for purposes of this Section shall be the fair
market value of such unit on the date of the claim as determined by the Board of
Directors of Nextera (the "Board"). The fair market value shall be determined in
good faith by the Board and the Board shall notify the Escrow Representative and
Escrow Agent in writing of its determination (the "Initial Valuation Notice").
If the Escrow Representative disputes the fair market value of the Escrow Units
as determined by the Board, then the Escrow Representative shall so notify the
Board and Escrow Agent in writing (the "Appraisal Notice") within ten (10)
business days of receipt of the Initial Valuation Notice. Within twenty (20)
business days of the receipt of the Appraisal Notice, the Board and the Escrow
Representative shall each appoint a professional appraiser to determine the fair
market value of the Escrow Units. Each appraiser shall have at least five (5)
years experience in appraising companies similar to Nextera. The two appraisers
shall within the succeeding twenty (20) day period after their selection,
attempt to reach agreement on the fair market value. If the




                                       4
<PAGE>   5

appraisers reach such agreement they shall so notify the Escrow Agent and their
agreement shall be final and binding on Buyer, Nextera, the Board, the Escrow
Representative, Seller, General Partner, Limited Partner, the Shareholders, and
their affiliates. If the appraisers fail to agree, they shall within ten (10)
days thereafter select a third appraiser with the same qualification
requirements, and the three (3) appraisers shall establish the fair market value
by majority vote within the succeeding twenty (20) day period and shall notify
the Escrow Agent of their determination. Such determination of the fair market
value shall be final and binding on Buyer, Nextera, the Board, the Escrow
Representative, Seller, the Shareholders, and their affiliates. In all events,
the appraisers selected shall be unaffiliated with and otherwise independent of
Buyer, Nextera, the Board, the Escrow Representative, Seller, General Partner,
Limited Partner, the Shareholders, and their affiliates. If the fair market
value of the Escrow Units, as determined by the appraisers, is less than or no
more than five percent (5%) greater than the value as determined by the Board,
then the Shareholders shall pay all costs associated with the appraisers. If the
fair market value as determined by the appraisers is more than five percent (5%)
greater than the value as determined by the Board, then Nextera shall pay for
all costs associated with the appraisers. In determining fair market value,
neither the Board nor any appraiser shall take into account (x) the value
assigned to the Nextera Class A Units in connection with the Purchase Agreement
or (y) any discount for a minority interest.

               To the extent Seller has transferred its rights to the Escrow
Units to General Partner and Limited Partner, the Escrow Units delivered to
Nextera in satisfaction of a claim shall be allocated among the General Partner
and Limited Partner so as to reduce each corporation's interest in the remaining
Escrow Units in proportion to their respective ownership percentages as set
forth on Exhibit A hereto. In the event that the Incorporation Transaction (as
defined in Section 5 below) has occurred, thereafter the Escrow Units delivered
to Nextera in satisfaction of a claim shall be allocated among the Shareholders
so as to reduce each Shareholder's interest in the remaining Escrow Units in
proportion to their respective ownership percentages as set forth on Exhibit A
hereto. Notwithstanding the foregoing, (i) any claim that is an Individual Claim
(as defined in the Purchase Agreement) shall be satisfied by reduction of the
interest in the Escrow Deposit of the Shareholder who committed fraud or who
made the representation, warranty or covenant from which the Individual Claim
arose and no other Shareholder shall have any liability therefor hereunder and
(ii) the satisfaction of one or more Individual Claims as describe in clause (i)
shall not increase the proportion of any subsequent claim for which any
Shareholder would have been responsible absent such prior satisfaction of such
Individual Claims. In the event that the Escrow Agent must make payment with a
number of units less than or different from the number of units represented by a
certificate in the Escrow Deposit, the Escrow Agent shall surrender such
certificate to Nextera and Nextera shall issue to the Escrow Agent certificates
of Nextera Class A Units identical in form but for the number of units as
necessary to allow for proper payment of the claim so long as the number of
units of the new certificates plus the amount of units used to satisfy such
claim shall be equivalent to the total number of units covered by the
surrendered certificate.

               4. Disputed Claims.



                                       5
<PAGE>   6


               (a) If the Escrow Representative shall dispute an indemnification
claim of Nextera as above provided, the Escrow Agent shall set aside a portion
of the Escrow Deposit sufficient to pay said claim in full as reasonably
determined by Nextera in good faith (the "Set Aside Amount"). Nextera shall
notify the Escrow Agent in writing of the Set Aside Amount. If Nextera notifies
the Escrow Agent in writing that it has made out-of-pocket expenditures in
connection with any such disputed claim, and provides paid receipts for such
expenditures, in addition to expenditures included in the Set Aside Amount, an
amount equal to such additional expenditures shall be added to the Set Aside
Amount. The appropriate number of Escrow Units in the Set Aside Amount shall be
determined by the procedure described in Section 3(b)(ii) above.

               (b) If the disputed indemnification claim has not been resolved
or compromised within sixty (60) days after the Escrow Agent's receipt of the
Escrow Representative's notice of dispute of the same, or in the event of a
third-party claim or suit, within fifteen (15) days after its resolution or
compromise, said indemnification claim shall be referred to the American
Arbitration Association, to be settled by binding arbitration in New York, New
York, in accordance with the commercial arbitration rules of the Association.
The fees and expenses of the arbitrator shall be borne equally by the
Shareholders on the one hand and Nextera on the other. In no event shall the
Escrow Agent be responsible for any fee or expense of any party to any
arbitration proceeding. The determination of the arbitrator as to the amount, if
any, of the indemnification claim which is properly allowable shall be
conclusive and binding upon the parties hereto and judgment may be entered
thereon in any court having jurisdiction thereof, including, without limitation,
any court in the State of New York. The arbitrator shall have the authority in
its discretion to award to the prevailing party reasonable costs and expenses
including attorney's fees and the cost of arbitration. The Escrow Agent shall
use its best efforts to make payment of such claim, as and to the extent
allowed, to Nextera out of the Set Aside Amount (or if insufficient, out of the
Escrow Deposit) within three (3) business days following the Escrow Agent's
receipt of said determination or as soon thereafter as possible.

               (c) Notwithstanding Section 4(b), if a disputed indemnification
claim has not been resolved or compromised as of the Termination Date (as
hereinafter defined), and such claim does not involve a third-party claim or
suit, Nextera and the Escrow Representative shall continue to negotiate in good
faith a settlement of such claims for a period of ten (10) days after the
Termination Date. If, after the expiration of such ten-day period, such
indemnification claim still has not been resolved or compromised, such claim
shall be settled in accordance with the arbitration provisions set forth in
Section 4(b).

               (d) It is understood and agreed that should any dispute arise
under this Section 4, the Escrow Agent, upon receipt of written notice of such
dispute or claim by the Escrow Representative, is authorized and directed to
retain in its possession without liability to anyone, the Set Aside Amount
relating to such dispute plus any expenditures of Nextera made pursuant to
Section 4(a) until such dispute shall have been settled pursuant to this Section
4. The Escrow Agent may, but shall be under no duty whatsoever to, institute or
defend any legal proceedings which relate to the Escrow Deposit.

               (e) In connection with the resolution of a disputed
indemnification claim, the arbitrator may award, in its discretion, to the
Shareholders interest on the amount by which the





                                       6
<PAGE>   7

Set Aside Amount exceeds the amount which the arbitrator determined would have
been a reasonable Set Aside Amount, computed from the Termination Date to the
date such Set Aside Amount is released from escrow if the arbitrator determines
that (i) Nextera had no reasonable basis for making the indemnification claim or
(ii) the Set Aside Amount as determined by Nextera had no reasonable relation to
the amount of the claim. The arbitrator may not award interest under this
Section 4(e) if Nextera's claim is occasioned by, or the Set Aside Amount
corresponds to the amount of, a third-party claim regardless of the merits of
such third-party claim.

               5. Incorporation Transaction; Exchange of Escrow Units. Pursuant
to that certain Share Exchange Agreement (the "Exchange Agreement") dated as of
the date hereof by and among Buyer, Nextera, the Partnership, General Partner,
Limited Partner and the Shareholders, the Shareholders shall exchange their
shares of capital stock of General Partner and Limited Partner for Newco Class A
Stock (as defined in the Exchange Agreement) and the remaining Escrow Units at
the time of the Incorporation Transaction (as defined in the Exchange Agreement)
shall be released from escrow under this Agreement and an appropriate number of
shares of Newco Class A Stock (as defined in the Exchange Agreement) shall be
delivered to the Escrow Agent in substitution for the Escrow Units. Following
the Incorporation Transaction, all references to Escrow Units in this Agreement
shall be deemed to include such shares of Newco Class A Stock. The Escrow Agent
shall follow the joint written instruction of Nextera and the Escrow
Representative in carrying out the provisions of this Section 5.

               6. Termination. This Agreement shall terminate on the date that
the Escrow Deposit is reduced to zero as the result of payments by the Escrow
Agent to Nextera in accordance with the provisions of Section 3 or Section 4.
If, however, the Escrow Deposit has not been reduced to zero as of the date that
is eighteen (18) months following the date of this Agreement (the "Termination
Date") and there are no outstanding indemnification claims on the Termination
Date of which Escrow Agent has received notice hereunder, the Escrow Agent shall
distribute the amount remaining in the Escrow Deposit to Seller or, to the
extent Seller has transferred to the General Partner and Limited Partner its
rights to the Escrow Deposit, the General Partner and Limited Partner in
accordance with their respective ownership percentages as set forth on Exhibit A
hereto, or, in the event that the Incorporation Transaction has occurred, to the
Escrow Representative for distribution to the Shareholders in accordance with
their respective ownership percentages as set forth on Exhibit A hereto. After
such payment this Agreement shall terminate; otherwise this Agreement shall
continue in effect until all indemnification claims Nextera has made pursuant to
Section 3 hereof on or prior to the Termination Date shall have been disposed
of. As of the Termination Date, an amount of the Escrow Deposit adequate to
cover all disputed and undisputed claims made by Nextera pursuant to Section 3
hereof will be held by the Escrow Agent (with the number of Escrow Units, if
any, to be retained determined in accordance with Section 3(b)(ii)), and the
Escrow Agent shall distribute on the Termination Date the balance, if any, of
the Escrow Deposit to Seller or, to the extent Seller has transferred to the
General Partner and Limited Partner its rights to the Escrow Deposit, the
General Partner and Limited Partner in accordance with their respective
ownership percentages as set forth on Exhibit A hereto, or, in the event that
the Incorporation Transaction has occurred, to the Escrow Representative for
distribution to the Shareholders in accordance with their respective ownership
percentages as set forth on Exhibit A hereto. At such time as all remaining
indemnification claims hereunder have been resolved and the Escrow Agent has
received a written notice executed by







                                       7
<PAGE>   8

Nextera and the Escrow Representative, or notification of a determination of an
arbitrator pursuant to Section 4(b), to that effect and any amounts to be
distributed to Nextera in connection therewith have been so distributed, the
Escrow Agent shall distribute the remaining Escrow Deposit, if any, to Seller
or, to the extent Seller has transferred to the General Partner and Limited
Partner its rights to the Escrow Deposit, to the General Partner and Limited
Partner in accordance with their respective ownership percentages as set forth
on Exhibit A hereto, or in the event that the Incorporation Transaction has
occurred or if, following a breach of Nextera's obligation to effect the
Incorporation Transaction under the Exchange Agreement, the General Partner and
Limited Partner have transferred to the Shareholders their rights to Nextera
Class A Units, to the Escrow Representative for distribution to the
Shareholders, in accordance with their respective ownership percentages as set
forth on Exhibit A hereto. The Escrow Representative shall notify the Escrow
Agent in writing upon Seller's transfer of its rights hereunder to General
Partner and Limited Partner, and Nextera, the Escrow Representative, General
Partner and Limited Partner shall take all necessary action to cause (i) the
certificates representing the Escrow Units registered in the name of the Seller
and the related stock powers or similar instruments executed by the Seller and
deposited with the Escrow Agent to be released from escrow and transferred to
General Partner and Limited Partner and (ii) new certificates registered in the
name of General Partner and Limited Partner, together with stock powers or
similar instruments duly signed in blank by General Partner and Limited Partner,
to be deposited with the Escrow Agent in substitution for the certificates
registered in the name of the Seller and the stock powers or similar instruments
executed by Seller.

               7. The Escrow Agent.

               (a) Direction from Nextera and Escrow Representative.
Notwithstanding anything herein to the contrary, the Escrow Agent shall promptly
dispose of all or any part of the Escrow Deposit as directed by a writing signed
by Nextera and Escrow Representative.

               (b) Reliance by Escrow Agent; Liability of Escrow Agent. Except
with respect to capitalized terms used herein and defined in the Purchase
Agreement or the Exchange Agreement, the Escrow Agent will not be subject to, or
be obliged to recognize, any other agreement between the parties hereto or
directions or instructions not specifically set forth as provided for herein.
The Escrow Agent will not make any payment or disbursement from or out of the
Escrow Deposit that is not expressly authorized pursuant to this Agreement. The
Escrow Agent undertakes to perform only such duties as are expressly set forth
herein. The Escrow Agent may rely and shall be protected in acting or refraining
from acting upon any written notice, instruction or request furnished to it
hereunder and believed by it to be genuine and to have been signed or presented
by the proper party or parties. The Escrow Agent shall be under no duty to
inquire into or investigate the validity, accuracy or content of any such
document. The Escrow Agent shall have no duty to solicit any payment which may
be due it hereunder. The Escrow Agent shall not be liable for any action taken
or omitted by it in good faith unless a court of competent jurisdiction
determines that the Escrow Agent's gross negligence and willful misconduct was
the primary cause of any loss to Buyer, Nextera, Seller, General Partner,
Limited Partner or the Shareholders. In the administration of the Escrow Deposit
hereunder, the Escrow Agent may execute any of its powers and perform its duties
hereunder directly or through agents or attorneys and may consult with counsel,
accountants and other skilled persons to be selected 







                                       8
<PAGE>   9

and retained by it. The Escrow Agent shall not be liable for anything done,
suffered or omitted in good faith by it in accordance with the advice or opinion
of any such counsel, accountants or other skilled persons. Buyer, Nextera,
Seller, General Partner, Limited Partner and the Shareholders jointly and
severally hereby agree to indemnify and hold the Escrow Agent and its directors,
officers, agents and employees (collectively, the "Indemnitees") harmless from
and against any and all claims, liabilities, losses, damages, fines, penalties,
and expenses, including out-of-pocket and incidental expenses and legal fees and
expenses ("Losses") that may be imposed on, incurred by, or asserted against the
Indemnitees or any of them for following any instructions or other directions
upon which the Escrow Agent is authorized to rely pursuant to the terms of this
Agreement. In addition to and not in limitation of the immediately preceding
sentence, the Buyer, Nextera, Seller, General Partner, Limited Partner and the
Shareholders also agree jointly and severally to indemnify and hold the
Indemnitees and each of them harmless from and against any and all Losses that
may be imposed on, incurred by, or asserted against the Indemnitees or any of
them in connection with or arising out of Escrow Agent's performance under this
Agreement, provided the Indemnitees have not acted with gross negligence or
engaged in willful misconduct. Anything in this Agreement to the contrary
notwithstanding, in no event shall the Escrow Agent be liable for special,
indirect or consequential loss or damage of any kind whatsoever (including but
not limited to lost profits). As between Buyer and Nextera on the one hand and
Seller, General Partner, Limited Partner and the Shareholders on the other, each
shall bear equally the indemnification obligations set forth in this Section
7(b). The provisions of this Section 7(b) shall survive the termination of this
Agreement and the resignation or removal of the Escrow Agent for any reason.

               (c) Fees and Expenses of the Escrow Agent. All fees of the Escrow
Agent for its services hereunder, together with any expenses reasonably incurred
by the Escrow Agent in connection with this Agreement, shall be shared equally
by Buyer on the one hand and the Seller, General Partner, Limited Partner and
the Shareholders on the other. The initial fees due the Escrow Agent to be paid
by the Seller, General Partner, Limited Partner and the Shareholders (which are
expected to be approximately $1,100) shall be paid in cash at the Closing and
reduced from the cash portion of the Purchase Price (as defined in the Purchase
Agreement). All other fees of the Escrow Agent in connection herewith shall be
due from the parties upon receipt of an invoice from the Escrow Agent delivered
to Nextera and the Escrow Representative.

               (d) Resignation and Removal of Escrow Agent; Successor Escrow
Agent.

                   (i) The Escrow Agent may resign from its duties hereunder by
giving each of the parties hereto not less than thirty (30) days prior written
notice of the effective date of such resignation (which effective date shall be
at least thirty (30) days after the date such notice is given). In addition, the
Escrow Agent may be removed and replaced on a date designated in a written
instrument signed by Nextera and the Escrow Representative and delivered to the
Escrow Agent. The parties hereto intend that a successor escrow agent mutually
acceptable to the Escrow Representative and Nextera will be appointed to fulfill
the duties of the Escrow Agent hereunder for the remaining term of this
Agreement in the event of the Escrow Agent's resignation or removal. Upon the
effective date of such resignation or removal, the Escrow Agent shall deliver
the property comprising the Escrow Deposit to such successor escrow agent,
together with an accounting of the investments held by it and all transactions
related to this

Agreement, including any distributions made and such records maintained by the
Escrow Agent in connection with its duties hereunder and other information with
respect to the Escrow Deposit as such successor may reasonably request. If on or
before the effective date of such resignation or removal, a successor escrow
agent has not been appointed, the Escrow Agent will thereupon deposit the Escrow
Deposit into the registry of a court of competent jurisdiction.

                          Upon written acknowledgment by a successor escrow
agent appointed in accordance with this Section 7(d)(i) of its agreement to
serve as escrow agent hereunder and the receipt of the property then comprising
the Escrow Deposit, the Escrow Agent shall be fully released and relieved of all
duties, responsibilities and obligations under this Agreement, except for those
arising under the last sentence of Section 7(b) of this Agreement, and such
successor escrow agent shall for all purposes hereof be the Escrow Agent.

                   (ii) Any corporation, association or other entity into which
the Escrow Agent may be converted or merged, or with which it may be
consolidated, or to which it may sell or otherwise transfer all or substantially
all of its corporate trust business, or any corporation, association or other
entity resulting from any such merger, conversion, consolidation, sale or other
transfer, shall, ipso facto, be and become successor Escrow Agent hereunder,
vested with all of the powers, discretions, immunities, privileges and all other
matters as was its predecessor, without the execution or filing of any
instrument or any further act on the part or any of the parties hereto, anything
herein to the contrary notwithstanding.

               8. Voting of Escrow Units. So long as any Escrow Units are
retained by the Escrow Agent, Seller or, to the extent Seller has transferred
its interest to General Partner and Limited Partner, General Partner and Limited
Partner in accordance with their respective ownership percentages as set forth
on Exhibit A hereto, or, in the event that the Incorporation Transaction has
occurred or if, following a breach of Nextera's obligation to effect the
Incorporation Transaction under the Exchange Agreement, the General Partner and
Limited Partner have transferred to the Shareholders their rights to Nextera
Class A Units, the Shareholders shall be entitled to exercise the voting power,
if any, with respect to in the Escrow Units, in accordance with their respective
ownership percentages as set forth on Exhibit A hereto.

               9. Governing Law. IT IS THE PARTIES' INTENT THAT THIS AGREEMENT
SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE
STATE OF NEW YORK (WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW).

               10. Counterparts. This Escrow Agreement may be executed in one or
more counterparts, all of which documents shall be considered one and the same
document.

               11. Notices. Any notice or other communication required or

               11. Certification of Tax Identification Number. The parties

Deposit is credited to the Escrow Deposit. The parties hereto understand that,
in the event their tax identification numbers are not certified to the Escrow
Agent, the Internal Revenue Code, as amended from time to time, may require
withholding of a portion of any interest or other income earned on the
investment of the Escrow Deposit.

               12. Force Majeure. Neither Buyer, Nextera, Seller, General
Partner, Limited Partner, the Shareholders nor the Escrow Agent shall be

modified, nor may compliance with any condition or covenant set forth herein be
waived, except by a writing duly and validly executed by each party hereto, or
in the case of a waiver, the party waiving compliance; provided, however, that,
except as specifically provided by Section 1(b) above, no amendment or
modification of this Agreement or waiver of compliance with any condition or
covenant that has been duly and validly executed in writing by the Escrow
Representative shall require the consent of, or execution thereof, by any other
Selling Party and shall be valid and binding without such consent or execution.
No course of conduct shall constitute a waiver of any of the terms and
conditions of this Escrow Agreement, unless such waiver is specified in writing,
and then only to the extent so specified. A waiver of any of the terms and
conditions of this Escrow Agreement on one occasion shall not constitute a
waiver of the other terms of this Escrow Agreement, or of such terms and
conditions on any other occasion.

               14. Reproduction of Documents. This Agreement and all documents
relating thereto, including, without limitation, (a) consents, waivers and
modifications which may hereafter be executed, and (b) certificates and other
information previously or hereafter furnished, may be reproduced by a
photographic, photostatic, microfilm, optical disk, micro-card, miniature
photographic or other similar process. The parties agree that any such
reproduction shall be admissible in evidence as the original itself in any
judicial or administrative proceeding, whether or not the original is in

regular course of business, and that any enlargement, facsimile or further

(1)      As soon as practicable after the date hereof, but in any event prior to
         the Closing Date, the parties hereto shall have caused the following
         actions to have occurred (the "Pre-Closing Steps"):

         (a)      Sibson Canada and 1053861 Ontario Limited ("SC HOLDCO") shall

                  will have no assets or liabilities nor will it carry 
<PAGE>   15
                                     - 10 -

                  on any business on or prior to closing and the parties hereby
                  understand and agree that the Representations and Warranties
                  are based on that assumption;

         (c)      Immediately following the continuance and incorporation
                  described above, an order of the Supreme Court of Nova Scotia
                  shall have been applied for and obtained under Section 134 of
                  the NS Act (the "AMALGAMATION ORDER"), approving the
                  amalgamation of Sibson Canada, SC Holdco and SC Unlimco to
                  form an unlimited liability company under the name "SIBSON
                  CANADA CO"; and

         (d)      As the first step of Closing and prior to the acquisition
                  contemplated in Section 2.2 hereof, Sibson Canada, SC Holdco
                  and SC Unlimco will be amalgamated (the "AMALGAMATION") by way
                  of Amalgamation Agreement under the NS Act and the resulting
                  company ("SC AMALCO") will be an unlimited liability company
                  under the NS Act. SC Amalco will have an authorized capital
                  consisting of 10,000,000 common shares and 10,000,000 Class A
                  common shares with the rights, privileges, restrictions and
                  conditions attaching to the existing common shares and Class A
                  common shares in the capital of Sibson Canada at the date
                  hereof.

(2)      Upon the Amalgamation, the shares of Sibson Canada, SC Holdco and SC
         Unlimco will be converted into shares of SC Amalco or cancelled as
         follows:

         (a)      The 10 voting shares of SC Holdco shall be converted into 210
                  common shares of SC Amalco, the 100 Class A shares of SC
                  Holdco shall be converted into 2,099 common shares of SC
                  Amalco, the 100 Class B shares of SC Holdco shall be converted
                  into 2,099 common shares of SC Amalco, the 100 Class C shares
                  of SC Holdco shall be converted into 2,099 common shares of SC
                  Amalco;

         (b)      All of the issued and outstanding common shares and Class A
                  common shares in the capital of Sibson Canada will be
                  converted into 3,494 common shares of SC Amalco on the basis
                  of 6.5065 common shares of SC Amalco for each common or Class
                  A common share of Sibson Canada, save and except the issued
                  and outstanding shares of Sibson Canada held by SC Holdco,
                  which will be cancelled without any repayment of capital in
                  respect thereof (fractions rounded as per Exhibit A); and

         (c)      All of the issued and outstanding shares in the capital of SC
                  Unlimco held by Sibson Canada will be cancelled without any
                  repayment of capital in respect thereof.

(3)      The parties acknowledge and agree that the Representations and
         Warranties of the SC Shareholders will be based upon the assumption
         that:

         (a)      following the continuance of Sibson Canada and SC Holdco under
                  the NS Act all of the property rights, assets and liabilities
                  of such corporations continue to be the property rights,
                  assets and liabilities of the continued companies, and ;
<PAGE>   16
                                     - 11 -


         (b)      upon the amalgamation of the continued Sibson Canada, the
                  continued SC Holdco and SC Unlimco (collectively, the
                  "Pre-Amalgamating Companies") all of the property of such
                  Pre-Amalgamating Companies shall become the property of SC
                  Amalco; Amalco becomes liable for all of the liabilities and
                  obligations of the Pre-Amalgamating Companies; the rights of
                  creditors and others against the property, rights and assets
                  of each of the Pre-Amalgamating Companies become rights
                  against the property, rights and assets of SC Amalco; and the
                  obligations, if any, of the Pre-Amalgamating Companies under
                  this agreement become the obligations of SC Amalco.

         (c)      The SC Shareholders shall have no liability with regard to any
                  warranty, breach of a representation or relating to the
                  Pre-Closing Steps.

(4)      Except where the context otherwise requires, any reference herein to
         "Sibson Canada" shall be deemed to include reference to Sibson Canada
         Inc., as continued under the NS Act and to SC Amalco, following the
         Amalgamation.

(5)      Notwithstanding anything to the contrary, and in particular section
         11.4, the parties acknowledge and agree that a certain letter agreement
         from Nextera to the SC Shareholders dated August 11, 1998 regarding the
         Pre-Closing Steps is in full force and effect in accordance with the
         terms thereof.

(6)      Intentionally Deleted

(7)      Legal fees shall be payable on Closing, by Sibson Canada to Donahue in
         the amount of CDN. $100,000.

(8)      The Exchangeable Shares, by virtue of their terms, the Support
         Agreement and the Exchange Trust Agreement, entitle the holders thereof
         to acquire Nextera Class A Units, or Newco Class A Stock (as
         hereinafter defined) on certain terms and conditions. Nextera shall
         take all steps in the United States and Ontario to ensure that the SC
         Shareholders are in no worse position than the sellers under the U.S.
         Purchase Agreement as a result of failure to obtain any regulatory
         approval that may be necessary recognizing (i) that the hold period
         imposed upon the SC Shareholders with respect to the Nextera Class A
         Units or Newco Class A Stock may, but not necessarily will, be greater
         than the hold period imposed on the Shareholders under the U.S.
         Purchase Agreement and (ii) that Nextera shall not be required to
         obtain listing of the Nextera Class A Units or Newco Class A Stock in
         Canada.

(9)      The Exchangeable Shares are fully transferable between the SC
         Shareholders.

SECTION 2.2         PURCHASE OF PURCHASED SHARES.

         Upon the terms and subject to the conditions contained herein, at the
Closing, the SC Shareholders will sell and the Canadian Buyer will purchase all
of the issued and outstanding shares of SC Amalco consisting of 10,001 common
shares, (collectively, the "PURCHASED SHARES") free and clear of all
Encumbrances.

         In consideration of the sale, and delivery of the Purchased Shares to
Canadian Buyer and in reliance upon the representations and warranties of the SC
Shareholders herein contained and made at the Closing and upon the terms and
subject to the satisfaction or waiver of the party entitled thereto of all of
the conditions set forth herein, Canadian Buyer agrees at the Closing to pay to
SC Shareholders for the Purchased Shares $3,105,532.50 which, together with
Nextera's/Canadian Buyer's performance of its other obligations pursuant to this
Agreement, shall constitute the entire consideration to be paid by Buyer
hereunder.

SECTION 2.4         SATISFACTION OF PURCHASE PRICE.

         The Canadian Buyer shall satisfy the purchase consideration for the
Purchased Shares as follows:

(2)      The SC Shareholders have delivered to Canadian Buyer true, correct and
         complete copies (or descriptions thereof with respect to oral Material
         Contracts) of all of the Material Contracts, including all amendments
         and supplements thereto. Other than the Material Contracts, the SC
         Shareholders have no other Contracts of the type described in clauses
         (a) through (m) above.

         necessary to enable it to fulfill when due, all of its respective
         material obligations under each such Material Contract. To the
         knowledge of the SC Shareholders, all other parties to such Material
         Contracts are currently in compliance in all material respects with the
         provisions thereof, no party is in Default in any respect thereunder
         and no notice of any such claim of Default relating thereto has been
         given to Sibson Canada or the SC Shareholders. To the knowledge of the
         SC Shareholders, there is no reason to believe that the services called
         for by any Material Contract between SC Shareholders and a client of SC
         Shareholders cannot be supplied substantially in accordance with the
         terms of such Material Contract, including time specifications, and
         Sibson Canada has no reason to believe that any Material Contract will
         upon performance by Sibson Canada result in a net loss to Sibson
         Canada.


SECTION 4.13  PERMITS. 

(1)      Sibson Canada has, and at all times has had, all Permits required under
         any Regulation (including Environmental Laws) in the operation of its
         Canadian Business or in the ownership of the Canadian Assets, except
         for those Permits the absence of which would not individually or in the
         aggregate have a material adverse effect. A complete list of such
         Permits is set forth in Schedule 4.13. Sibson Canada is not in Default,
         nor has it received any notice of any claim of Default, with respect to
         any such Permit. To the knowledge of the SC Shareholders, no present or
         former shareholder, director, officer or employee of Sibson Canada or
         any affiliate thereof, or any other person, firm, corporation or other

         (direct or indirect) in any such Permit.

         governmental or regulatory body or authority, or any other person or
         entity, is required to be made or obtained by Sibson Canada in

such entity or person or (d) in which Sibson Canada is a plaintiff, including

knowledge of the SC Shareholders, is there any reasonable basis for any such
Action. Sibson Canada is not in Default with respect to or subject to any Court
Order, and there are no unsatisfied judgments against Sibson Canada, the
Canadian Business or the Canadian Assets. There is not a reasonable likelihood
of an adverse determination of any pending Actions that could have a material
adverse effect. There are no Court Orders or agreements with, or liens by, any

         Employee Plan.

(6)      No event has occurred in connection with which Sibson Canada or any
         Employee Program, directly or indirectly, could be subject to any

         relating to any Employee Programs or (B) pursuant to any obligation of
         Sibson Canada to indemnify any person against liability incurred under
         any such Regulation or order as they relate to the Employee Programs.

(7)      Except as described on Schedule 4.26, neither the execution and
         delivery of this Agreement nor the consummation of the transactions
         contemplated hereby will result in the acceleration or creation of any
         rights of any person to benefits under any Employee Program (including,
         without limitation, the acceleration of the vesting or exercisability
         of any stock options, the acceleration of the vesting of any restricted
         stock, or the acceleration or creation of any rights under any
         severance, parachute or change in control agreement).

(8)      Each Employee Program and related trust agreement or other funding
         instrument, as applicable, which covers or has covered employees or
         former employees of Sibson Canada (with respect to their relationship
         with such entities) is legally valid and binding and in full force and
         effect.

                  provide) benefits under such Employee Program, or has any
                  obligation (by agreement or under applicable law) to
                  contribute to or provide benefits under such Employee Program,
                  or if such Employee Program provides benefits to or otherwise

                  acting on behalf of the SC Shareholder or any such affiliates

         (h)      Such SC Shareholder understands that the Securities have not
                  been registered under the Securities Act by reason of a
                  specific exemption therefrom, and may not be transferred or
                  resold except pursuant to an effective registration statement
                  or exemption from registration (and based upon an opinion of
                  counsel, acting reasonably, if Nextera or Newco so requests)

                           THE MEANING GIVEN SUCH TERM IN REGULATION S) IN THE
                           UNITED STATES, THAT IT WILL NOT BECOME AN AFFILIATE
                           OF THE COMPANY AS A RESULT OF THE PURCHASE OF THE

                           OR TO A U.S. PERSON IF THE SHARES HAVE BEEN
                           REGISTERED UNDER THE SECURITIES ACT, OR AN EXEMPTION
                           FROM REGISTRATION IS AVAILABLE.

                  (iv)     Any legend required to be placed thereon by
                           applicable federal or state securities laws. 

         (i)      Such SC Shareholder has substantial experience in evaluating
                  and investing in private placement transactions of securities
                  in companies similar to Nextera and Newco so that he is
                  capable of evaluating the merits and risks of acquiring the
                  Securities to be issued to such SC Shareholder and has the
                  capacity to protect his own interests. Such SC Shareholder
                  must bear the economic risk of holding the Securities
                  indefinitely unless such securities are registered pursuant to
                  the Securities Act, or an exemption from registration is
                  available for the disposition thereof. Such SC Shareholder
                  understands that there is no assurance that any exemption from
                  registration under the Securities Act will be available.

         (j)      Such SC Shareholder is acquiring the Securities for his own
                  account for investment only, and not with the view to, or for
                  resale in connection with,

                                      -36-


                  any distribution thereof. It understands that the Securities
                  to be acquired has not been, and will not be, registered under
                  the Securities Act by reason of a specific exemption from
                  registration provisions of the Securities Act, the
                  availability of which depends upon, among other things, the
                  bona fide nature of the investment intent and the accuracy of
                  such SC Shareholder's representations as expressed herein.

         (k)      Such SC Shareholder understands that no public market now
                  exists for any of the securities issued by Nextera or Newco
                  and that neither Nextera or Newco has made any assurances that
                  a public market will ever exist for such securities.

         (l)      Such SC Shareholder has received and read the Nextera business
                  plan and financial statements and has had an opportunity to
                  discuss Nextera's business, management and financial affairs
                  with its management. Such SC Shareholder has also had an
                  opportunity to ask questions of and receive answers from
                  officers of Nextera regarding the terms and conditions of
                  acquiring the Securities pursuant to this Agreement, which
                  questions were answered to such Shareholder's satisfaction.
                  

SECTION 4.36  AMOUNTS OWING TO SC SHAREHOLDERS. 

         Both parties agree that there are shareholder loans owing to the SC
Shareholders by Sibson Canada (the "Shareholder Loans") as listed in Schedule
4.36. Such amounts will be evidenced in promissory notes delivered at Closing.
After closing the Principals of Sibson Canada can distribute cash flow
permitting in ordinary course.

         Shares will be issued as fully paid and non-assessable free and clear
         of any and all Encumbrances, and Nextera and Canadian Buyer have no

                  judgment or decree to which Nextera, its Subsidiaries or the
                  Canadian Buyer is bound or affected, or result in the creation
                  or imposition of any mortgage, pledge, lien, security interest
                  or other charge or similar encumbrance on any of the assets or
                  capital stock of Nextera or Canadian Buyer and which is
                  material to the business and financial condition of Nextera or
                  Canadian Buyer on a consolidated basis, except in the case of
                  clause (b), for such breaches, defaults, accelerations or
                  terminations as would not, individually or in the aggregate,
                  have a material adverse effect. 

SECTION 5.3  LITIGATION. 

         Other than as set forth on Schedule 5.3, there are no Actions pending
or to the knowledge of Nextera, and Canadian Buyer, threatened or anticipated
(a) against, related to or affecting (i) Nextera and its Subsidiaries on a
consolidated basis (including with respect to Environmental Laws) or (ii) any

or any of their officers, directors or managers, or (d) in which Nextera or its

behalf of any of Nextera or its Subsidiaries. Neither Nextera nor any of its
Subsidiaries are in Default with respect to or subject to any Court Order, and
there are no unsatisfied judgments against Nextera or its Subsidiaries. There is
not a reasonable likelihood of an adverse determination of any pending Actions
that could have a materially adverse effect. There are no Court Orders or
agreements with, or liens by, any governmental authority or quasi-governmental
entity relating to any Environmental Law which regulates, obligates, binds or in
any way affects Nextera or its Subsidiaries.

SECTION 5.4                NO BROKERS.

            Neither Nextera nor Canadian Buyer nor any of their officers,

additional membership interests of any class of Nextera. Schedule 5.5 sets forth
a list of all agreements, if any, instruments and undertakings, relating to the

            the Audited Financial Statements (the "NEXTERA
<PAGE>   45
                                      -40-



         FINANCIAL STATEMENTS"). The December 31, 1997 balance sheet is
         hereinafter referred to as the "NEXTERA BALANCE SHEET" and December 31,
         1997 is hereinafter referred to as the "NEXTERA BALANCE SHEET DATE."
         The Nextera Financial Statements have been prepared in accordance with
         generally accepted accounting principles (subject to normal year-end
         adjustments in the case of the Interim Financial Statements) applied
         consistently during the period covered thereby, and said Audited
         Financial Statements present fairly in all material respects the
         consolidated financial condition of Nextera at the date of said
         statements and the consolidated results of its operations for the
         period covered thereby and the Interim Financial Statements present
         fairly and completely in all material respects the information to be
         shown thereon.

(2)      Except as set forth on Schedule 5.7, as of the date hereof and as of
         the Closing, Nextera and its Subsidiaries and Canadian Buyer do not
         have any Liabilities of any nature, whether accrued, absolute or
         contingent (including without limitation, Liabilities as guarantor or
         otherwise with respect to obligations of others, or Liabilities for any
         Tax due or then accrued or to become due or contingent or potential
         Liabilities relating to activities of Nextera or any Subsidiary of
         Nextera or Canadian Buyer or the conduct of any of the businesses prior
         to the date hereof or the Closing, as the case may be, regardless of
         whether claims in respect thereof had been asserted as of such date),
         except Liabilities (i) stated or adequately reserved against on the
         Nextera Balance Sheet or the notes thereto, or (ii) incurred or arising
         in the ordinary course of business of Nextera or any Subsidiary of
         Nextera after the Nextera Balance Sheet Date, (iii) disclosed in this
         Article 5 or on the Nextera Disclosure Schedule or (iv) future
         performance obligations under contracts and leases, none of which
         relates to any default, breach of warranty, tort infringement, or
         violation of any Regulation or Court Order or arose out of any action.

(3)      Nextera has delivered to SC Shareholders the following unaudited pro
         forma financial statements, copies of which are attached hereto as
         Schedule 5.7: a consolidated balance sheet of Nextera and its
         subsidiaries as of June 30, 1998 and a consolidated statement of profit
         and loss of Nextera for the six months ended June 30, 1998 (the "Pro
         Forma Statements"). The Pro Forma Statements have been prepared giving
         effect to the consummation of each acquisition made by Nextera
         subsequent to January 1, 1998 (including pursuant to this Agreement and
         the acquisition of Sibson Canada). The Pro Forma Statements have been
         prepared based on information Nextera believes to be reasonable as of
         the date of delivery thereof, and present fairly in all material
         respects on a pro forma basis the estimated financial position of
         Nextera as of June 30, 1998 and results of operations for the six
         months then ended, assuming that the events specified in the preceding
         sentence had actually occurred. The Pro Forma Statements are not
         necessarily indicative of the financial position or results of
         operations that would have been obtained had the pro forma events
         actually occurred and should be read in conjunction with the Nextera
         Financial Statements provided to SC Shareholders.

         against Nextera, any L.L.C. Subsidiary or any corporate Subsidiary that
         has not been resolved and paid in full. There are no outstanding
         waivers, extensions, or comparable consents regarding the application
         of the statute of limitations with respect to any Taxes or Tax Returns
         that have been given by Nextera, any L.L.C. Subsidiaries or any
         corporate Subsidiary (including the time for filing of Tax Returns or
         paying Taxes) and neither, Nextera, any L.L.C. Subsidiary or any
         corporate Subsidiary has any pending requests for any such waivers,
         extensions, or comparable consents.

(5)      No audit or other proceeding by any federal, state, provincial, local
         or foreign court, governmental, regulatory, administrative or similar
         authority is presently pending with respect to any Taxes or Tax Return
         of Nextera any L.L.C. Subsidiary or any corporate Subsidiary, and
         neither, Nextera, any L.L.C. Subsidiary nor any corporate Subsidiary
         has received written notice of any pending audits or proceedings.

(6)      Nextera, each L.L.C. Subsidiary and each corporate Subsidiary have
         established adequate reserves in accordance with generally accepted
         accounting principles for all Taxes not yet due and payable, which
         reserves are set forth in Schedule 5.8.

(7)      Nextera, each L.L.C. Subsidiary and each corporate Subsidiary have
         complied in all material respects with all applicable laws, rules and
         regulations relating to the payment and withholding of Taxes
         (including, without limitation, withholding of Taxes pursuant to
         Sections 1441, 1442, 1445 and 1446 of the Internal Revenue Code or
         similar provisions under any applicable state, provincial and foreign
         laws) and have, within the time and the manner prescribed by law, paid
         over to the proper governmental authorities all amounts so withheld.

(8)      Neither Nextera, any L.L.C. Subsidiary nor any corporate Subsidiary is
         a party to, is not bound by any obligation under any Tax sharing
         allocation or indemnity agreement or similar contract or arrangement.

                                      -42-

         characterized as a partnership for federal and applicable state and
         local income Tax purposes.

(10)     No power of attorney granted by Nextera, any L.L.C. Subsidiary or any
         corporate Subsidiary with respect to any Taxes is currently in force.

(11)     Other than its own operating agreement, Nextera is not subject to any
         joint venture, partnership or other arrangement or contract that is
         treated as a partnership for U.S. federal income Tax purposes.

(12)     There is no expectation that any taxing authority may claim or assess
         any material amount of Taxes payable by Nextera, any L.L.C. Subsidiary
         or any corporate Subsidiary for any period ending on or prior to the
         Closing Date and there are no facts which would constitute grounds for
         the assessment of any material amount of Taxes payable by Nextera, any
         L.L.C. Subsidiary or any corporate Subsidiary for any period ending on
         or prior to the Closing Date.

<PAGE>   48
                                      -43-

         (j)      Disposition or lapsing of any Proprietary Rights or any

SECTION 5.10                        [INTENTIONALLY DELETED].

SECTION 5.11                        COMPLIANCE WITH LAWS.

         Nextera and each of its Subsidiaries has been and are in substantial
compliance with all Regulations relating to the operation of Nextera and each of
its Subsidiaries except in each case where such non-compliance would not
individually or in the aggregate have a material adverse effect. Within the last
five years, neither Nextera or any of its Subsidiaries have received any notice
to the effect that, or otherwise been advised that, they are not in compliance
with any such Regulations or Court Orders, and Nextera and Canadian Buyer have
no reason to anticipate that any existing circumstances are likely to result in
violations of any of the foregoing.

SECTION 5.12                        PROPRIETARY RIGHTS.

         (a)      Proprietary Rights. Schedule 6.13 lists: (i) for each
                  registered Trademark of Nextera or any Subsidiary, the
                  application serial number of registration number, the class of
                  goods covered and the expiration date for each country in
                  which a Trademark has been registered and (ii) for each
                  registered Copyright of Nextera or any Subsidiary, the number
                  and date of filing for each country in which a Copyright has
                  been filed. Other than the items set forth on Schedule 5.12
                  and other than the unregistered service/trade name "Nextera
                  Enterprises" and variations thereof, there are no Proprietary
                  Rights used by Nextera or any Subsidiary that are material to
                  the conduct of its business. Nextera or any Subsidiary has no
                  patents or registered designs nor has it filed any patent
                  applications or registered design applications.

                                      -44-



         (b)      Royalties and Licenses. Except as set forth on Schedule 6.13
                  neither Nextera nor any Subsidiary, has any obligation to
                  compensate any person for the use of any such Proprietary
                  Rights nor has Nextera or any Subsidiary granted to any person
                  any license, option or other rights to use in any manner any
                  of such Proprietary Rights, whether requiring the payment of
                  royalties or not.

         (c)      Ownership and Protection of Proprietary Rights. Except as set
                  forth on Schedule 5.12, Nextera and/or its Subsidiaries own or
                  have a valid right to use each of such Proprietary Rights.
                  Except as set forth in Schedule 5.12, no other person (i) has
                  notified Nextera or any Subsidiary that it is claiming any
                  ownership of or right to use such Proprietary Rights, or (ii)
                  to the knowledge of Nextera and its Subsidiaries, is
                  infringing upon any such Proprietary Right in any way. To the
                  knowledge of Nextera and its Subsidiaries, except as set forth
                  on Schedule 5.13, use of such Proprietary Rights by Nextera or
                  any Subsidiary does not and will not conflict with, infringe
                  upon or otherwise violate the valid rights of any third party
                  in or to such Proprietary Rights, and no Action has been
                  instituted against or notices received by Nextera or any
                  Subsidiary that are presently outstanding alleging that use of
                  the Proprietary Rights by Nextera or any Subsidiary infringes
                  upon or otherwise violates any rights of a third party in or
                  to such Proprietary Rights.

or similar instrument requested by any lessor or sublessor and which is
reasonably acceptable to Buyer in connection with the obtaining of any consent

<PAGE>   50
                                      -45-


be required to make any payments, commence litigation or agree to modifications

(1)      At the Closing Nextera agrees to grant to Employees of Sibson Canada
         options under the Amended and Restated Equity Participation Plan
         effective as of July 28, 1998 (the "Equity Participation Plan") a true
         and correct copy of which is attached hereto as Exhibit K and in the
         forms of related agreements attached hereto as Exhibit K-1 for
         employees who are also Principals and Exhibit K-2 for employees who are
         not Principals, which grants shall consist options to purchase 23,000
         Nextera Class A Units to be distributed as set forth in a letter of
         even date herewith from SC Shareholders to Nextera which letter makes
         specific reference to this Section 6.6. Such options shall have an
         exercise price of $7.50 per share and shall vest at the rate of
         twenty-five percent (25%) per year over four (4) years. In connection
         with the U.S. Purchase Agreement, Nextera has agreed to make available
         to Buyer (as defined under the Buyer Operating Agreement) an additional
         pool of options to purchase 100,000 Nextera Class A Units for hiring
         purposes and performance recognition in calendar year 1998 subject to
         Nextera's review and approval and with such terms and conditions as may
         be determined by Nextera, of which options to purchase 30,000 Nextera
         Class A Units have been allocated as set forth in the letter referred
         to in the preceding sentence.

(2)      Nextera has duly adopted the Equity Participation Plan attached as
         Exhibit K and form of related agreement in the forms attached as
         Exhibit K-1 and K-2 hereto. The SC Shareholders acknowledge that (a)
         the terms of the options are governed by such

                                      -49-

         Equity Participation Plan attached as Exhibit K and related agreements
         in the forms attached as Exhibit K-1 and K-2; and (b) the Tax
         consequences of the options are materially different in a limited
         liability company as compared to a corporate structure, and the SC
         Shareholders have been advised by their own Tax advisors of such Tax
         consequences.

SECTION 6.7                ADDITIONAL UNITS.

         service offerings existed immediately prior to the Closing; provided,
         however, that Canadian Buyer (i) may make available additional service
         offerings and (ii) may eliminate existing service offerings if the
         gross revenues and/or net profits derived from such offerings are
         determined by Nextera and Canadian Buyer to be inadequate to maintain
         such service offerings.

(2)      Canadian Buyer and Nextera hereby confirms that as of the date hereof
         they intend (i) to use the "SIBSON & COMPANY, L.L.C., A NEXTERA

         (or some other entity controlled by Nextera) to conduct the Business
         for the foreseeable future under the present name of Business. The
         parties acknowledge that the intention of Canadian Buyer and Nextera
         with respect to this Section 6.6(b) is not a binding commitment on the
         part of Canadian Buyer or Nextera.

based upon any of the following matters:

         (a)      Fraud, intentional misrepresentation or the cause or knowledge
                  of a deliberate or wilful breach of any representations,
                  warranties or covenants of Nextera and/or Canadian Buyer with
                  respect to this Agreement in connection with the transactions
                  contemplated by this Agreement; and

         (b)      Any breach of any representation, warranty or covenant made by
                  the Nextera and/or Canadian Buyer in this Agreement or in any
                  certificate or schedule delivered by Nextera and/or the
                  Canadian Buyer hereunder.

SECTION 9.4         LIMITATION ON INDEMNIFICATION BY NEXTERA AND CANADIAN BUYER.

         Notwithstanding the foregoing, (a) no indemnification shall be
payable to the SC Shareholders Indemnified Parties with respect to claims
asserted pursuant to Section 9.3(b) above after the date which is eighteen (18)
months after the Closing, (b) and the aggregate amount to be payable to all SC
Shareholders Indemnified Parties pursuant to Section 12.3 shall not exceed
$2,047,299 and (c) Nextera and Canadian Buyer shall have no obligation for

representations, warranties or covenants of Canadian Buyer under this Agreement
or in any certificate, schedule or exhibit delivered pursuant hereto or a breach
of Sections 6.6 through 6.8 shall not be subject to any of the limitations set
forth in this Section 9.4.

SECTION 9.5         NOTICE; DEFENSE OF CLAIMS.

         An indemnified party shall make claims for indemnification hereunder by
giving written notice thereof to the indemnifying party promptly on discovery
and in any event within the period in which indemnification claims can be made
hereunder. If indemnification is sought for a claim or liability asserted by a
third party, the indemnified party shall also give written notice thereof to the
indemnifying party promptly after it receives notice of the claim or liability
being asserted, but the failure to do so shall not relieve the indemnifying
party from any liability except to the extent that it is prejudiced by the
failure or delay in giving such notice. Such notice shall summarize the basis
for the claim for indemnification and any claim or liability being asserted by a
third party. Within 20 days after receiving such notice the indemnifying party
shall give written notice to the indemnified party stating whether it disputes
the claim for indemnification and whether it will defend against any third party
claim or liability at its own cost and expense. If the indemnifying party fails
to give notice that it disputes an indemnification claim within 20 days after
receipt of notice thereof,
<PAGE>   64
                                     - 59 -


it shall be deemed to have accepted and agreed to the claim, which shall become
immediately due and payable. The indemnifying party shall be entitled to direct
the defense against a third party claim or liability with counsel selected by it
(subject to the consent of the indemnified party, which consent shall not be
unreasonably withheld) as long as the indemnifying party is conducting a good
faith and diligent defense and to compromise or settle it with consent of the
indemnified party, which consent shall not be unreasonably withheld. The
indemnified party shall at all times have the right to fully participate at its
own expense in the defense of a third party claim or liability, directly or
through counsel; provided, however, that if the named parties to the action or
proceeding include both the indemnifying party and the indemnified party and the
indemnified party is advised that representation of both parties by the same
counsel would be inappropriate under applicable standards of professional
conduct, the indemnified party may engage separate counsel at the expense of the
indemnifying party. If no such notice of intent to dispute and defend a third
party claim or liability is given by the indemnifying party, or if such good
faith and diligent defense is not being or ceases to be conducted by the
indemnifying party, the indemnified party shall have the right, at the expense
of the indemnifying party, to undertake the defense of such claim or liability
(with counsel selected by the indemnified party), and to compromise or settle
it, with consent of the indemnifying party, which consent shall not be
unreasonably withheld. If the third party claim or liability is one that by its
nature cannot be defended solely by the indemnifying party, then the indemnified
party shall make available such information and assistance as the indemnifying
party may reasonably request and shall cooperate with the indemnifying party in
such defense, at the expense of the indemnifying party.

SECTION 9.6         SATISFACTION OF SC SHAREHOLDERS INDEMNIFICATION OBLIGATIONS.

         Nextera shall bring and control all indemnification claims hereunder
and under the Share Exchange Agreement on behalf of the Buyer Indemnified
Parties, including without limitation Canadian Buyer. In order to satisfy the
indemnification obligations of the SC Shareholders hereunder and under the
Exchange Agreement, Nextera shall proceed first directly against the Escrow
Amount as further set forth in the Escrow Agreement and then may proceed
directly against the SC Shareholders subject to the limitations set forth
herein. A Buyer Indemnified Party may proceed against the SC Shareholder of its
choosing subject to the limitations set forth in the Agreement.

SECTION 9.7         USE OF NEXTERA CLASS A UNITS.

         To the extent indemnification claims exceed the Escrow Deposit (as
defined in the Escrow Agreement), the SC Shareholders may, at their option,
elect to satisfy any indemnification claims under this Agreement by delivering
to the indemnified party Exchangeable Shares issued pursuant to Section 2.3 or
any securities into which such Exchangeable Shares may be converted into, or
exchanged for, including, without limitation Nextera Class A Units. To the
extent that Exchangeable Shares (or such other securities) are used to satisfy
indemnification obligations under this Agreement, such shares shall be valued in
accordance with the terms of the Escrow Agreement. No statement of value in this

<PAGE>   69
                                     - 64 -

                                ESCROW AGREEMENT

and the SC Shareholders, Canadian Buyer is purchasing all of the issued and
outstanding shares in Sibson Canada;

         WHEREAS, the SC Shareholders have agreed to indemnify Canadian Buyer
and Nextera against certain breaches of the representations, warranties and
covenants made by the SC Shareholders in the Purchase Agreement and against
certain other matters as specified in Article 9 of the Purchase Agreement; and

         WHEREAS, to secure payment of the SC Shareholders' indemnification
obligations, 59,052 Exchangeable Shares of the Canadian Buyer (the "Escrow
Shares" and together with additions to or earnings on the same, the "Escrow
Deposit") are being deposited, pursuant to Section  2.4 of the Purchase
Agreement, in escrow to be held as hereinafter provided.

                  Escrow Shares have been issued in the name of the SC
                  Shareholders, and shall be accompanied by stock powers or
                  similar instruments duly signed in blank by the SC
                  Shareholders. The Escrow Deposit shall be held in escrow in an
                  account designated as the Sibson Canada Account or an account
                  having such other similar designation, subject to the terms
                  and conditions set forth herein. The Escrow Agent shall invest
                  all cash, if any, held as part of the Escrow Deposit only in
                  such specific investments as Nextera and the Escrow
                  Representative (as hereinafter defined) shall from time to
                  time jointly direct in writing to the Escrow Agent; provided,
                  however, that such investments shall be limited to:

                  (i)      time and demand deposits, certificates of deposit and
                           acceptances, maturing within ninety (90) days from
                           the date of acquisition thereof, issued by state and
                           national banks located in the United States of
                           America, including the Escrow Agent or any of its
                           affiliates, and having capital, surplus and profits

                           fund for which the Escrow Agent or an affiliate of
                           the Escrow Agent serves as investment manager,
                           administrator, shareholder servicing agent, and/or
                           custodian or subcustodian, notwithstanding that (i)
                           the Escrow Agent or an affiliate of the Escrow Agent
                           receives fees from such funds for services rendered
                           or (ii) services performed for such funds and
                           pursuant to this Agreement may at times duplicate
                           those provided to such funds by the Escrow Agent or
                           its affiliates.

         Until further written notice, cash in the Escrow Deposit shall be
invested in Vista Prime Money Market Fund. Unless otherwise directed in writing
by the Escrow Representative and Nextera, the Escrow Agent shall not invest all
or any portion of the Escrow Deposit in any investment if the maturity date of
such investment is later than the Termination Date (as defined below).

         (b)      Escrow Representative: Michael McInerney shall serve as the
                  exclusive representative of the SC Shareholders with respect
                  to the Escrow Deposit and this Agreement (the "Escrow
                  Representative"). If, for any reason, the Escrow
                  Representative shall be either unable or unwilling to serve, a
                  successor Escrow Representative shall be appointed by written
                  consent of the SC Shareholders and all references to the
                  Escrow Representative shall be deemed to include such
                  successor. Each SC Shareholder whose signature appears below
                  expressly agrees that this Agreement may be amended or
                  modified, and compliance with any condition or covenant may be
                  waived without the consent of, or execution thereof by, such
                  SC Shareholder if the Escrow Representative agrees to such
                  amendment or modification or grants such waiver, in each case
                  by a writing duly and validly executed by the Escrow
                  Representative as provided in Section  14; provided, however,
                  that the Escrow Representative will not enter into any such
                  amendment or modification or waive any condition or covenant
                  that materially and adversely affects any SC Shareholder
                  differently than all other SC Shareholders affected thereby
                  without the consent of such SC Shareholder.

2.       Amounts Earned on Escrow Deposit: Tax Matters. All amounts earned, paid
         or distributed with respect to the Escrow Deposit, if any, (whether
         interest, dividends, 
<PAGE>   3
                                     - 3 -


         distributions from Nextera with respect to the Escrow Shares or
         otherwise) shall become a part of the Escrow Deposit, shall be held
         hereunder upon the same terms as the original Escrow Deposit and shall
         be distributed together with the underlying portion of the original
         Escrow Deposit pursuant to the terms of this Agreement. The parties
         agree that the SC Shareholders will include all amounts earned on the
         Escrow Deposit (or allocated or distributed with respect thereto) in
         their gross income for federal, provincial and local income tax
         (collectively, "income tax") purposes and pay any income tax resulting
         therefrom, pro rata in accordance with their combined ownership
         percentage as set forth on Exhibit A.

3.       Claims Against Escrow Deposit.

         (a)      At any time or times prior to the Termination Date (as
                  hereinafter defined), Nextera, or any successor of Nextera,
                  may make claims against the Escrow Deposit for indemnification
                  pursuant to and in accordance with Article 9 of the Purchase
                  Agreement. Nextera shall notify the Escrow Representative and
                  the Escrow Agent in writing promptly upon determination to
                  make a claim and in any event prior to the expiration of this
                  Agreement of each such claim, including a summary of the
                  amount of and bases for such claim. If the Escrow
                  Representative shall dispute such claim, the Escrow
                  Representative shall give written notice thereof to Nextera
                  and to the Escrow Agent within thirty (30) days after receipt
                  of notice of Nextera's claim, in which case the Escrow Agent
                  shall continue to hold the Escrow Deposit in accordance with
                  the terms of this Agreement; otherwise, such claim shall be
                  deemed to have been acknowledged to be payable out of the
                  Escrow Deposit in the full amount thereof and the Escrow Agent
                  shall use its best efforts to pay such claim to Nextera within
                  three (3) business days after expiration of said thirty (30)
                  day period or as soon thereafter as possible following the
                  determination of the fair market value of the Escrow Shares
                  pursuant to Section 3(b)(ii) below. If the amount of the claim
                  exceeds the value of the Escrow Deposit, the Escrow Agent
                  shall have no liability or responsibility for any deficiency.

         (b)      The Escrow Agent shall follow the procedure below in making
                  any payment in satisfaction of a claim against the Escrow
                  Deposit:

                  (i)      The Escrow Agent shall make such payment first from
                           cash additions to or earnings on the Escrow Shares,
                           if any, until all cash in the Escrow Deposit has been
                           exhausted.

                  (ii)     To the extent that any claim exceeds the amount of
                           cash in the Escrow Deposit, the Escrow Agent shall
                           make payment from the Escrow Shares in such number of
                           Escrow Shares (computed to the nearest whole unit)
                           having a value equal to the value of the claim not
                           satisfied by cash payment. Any payment of Escrow
                           Shares by the Escrow Agent to Nextera shall be
                           treated as a sale by the SC Shareholders of such
                           Escrow Shares for the value described herein. The
                           value of an Escrow Unit for purposes of this Section
                           shall be the fair market value of a Class A Common
                           Unit of Nextera, or after the Incorporation

                           Transaction (as defined in that certain Share
                           Exchange Agreement dated as of August 31, 1998 by and
                           among Nextera, the SC Shareholders and the other
                           parties listed on the signature pages thereto (the
                           "Share Exchange Agreement")), a share of Class A
                           Common Stock of Newco (as defined in the Exchange
                           Agreement), on the date of the claim as determined by
                           the Board of Directors of Nextera (the "Board"). The
                           fair market value shall be determined in good faith
                           by the Board and the Board shall notify the Escrow
                           Representative and Escrow Agent in writing of its
                           determination (the "Initial Valuation Notice"). If
                           the Escrow Representative disputes the fair market
                           value of the Escrow Shares as determined by the
                           Board, then the Escrow Representative shall so notify
                           the Board and Escrow Agent in writing (the "Appraisal
                           Notice") within ten (10) business days of receipt of
                           the Initial Valuation Notice. Within twenty (20)
                           business days of the receipt of the Appraisal Notice,
                           the Board and the Escrow Representative shall each
                           appoint a professional appraiser to determine the
                           fair market value of the Escrow Shares. Each
                           appraiser shall have at least five (5) years
                           experience in appraising companies similar to
                           Nextera. The two appraisers shall within the
                           succeeding twenty (20) day period after their
                           selection, attempt to reach agreement on the fair
                           market value. If the appraisers reach such agreement
                           they shall so notify the Escrow Agent and their
                           agreement shall be final and binding on Canadian
                           Buyer, Nextera, the Board, the Escrow Representative,
                           and the SC Shareholders, and their affiliates. If the
                           appraisers fail to agree, they shall within ten (10)
                           days thereafter select a third appraiser with the
                           same qualification requirements, and the three (3)
                           appraisers shall establish the fair market value by
                           majority vote within the succeeding twenty (20) day
                           period and shall notify the Escrow Agent of their
                           determination. Such determination of the fair market
                           value shall be final and binding on Canadian Buyer,
                           Nextera, the Board, the Escrow Representative, and
                           the SC Shareholders, and their affiliates. In all
                           events, the appraisers selected shall be unaffiliated
                           with and otherwise independent of Canadian Buyer,
                           Nextera, the Board, the Escrow Representative, and
                           the SC Shareholders, and their affiliates. If the
                           fair market value of the Escrow Shares, as determined
                           by the appraisers, is less than or no more than five
                           percent (5%) greater than the value as determined by
                           the Board, then the SC Shareholders shall pay all
                           costs associated with the appraisers. If the fair
                           market value as determined by the appraisers is more
                           than five percent (5%) greater than the value as
                           determined by the Board, then Canadian Buyer and
                           Nextera shall pay for all costs associated with the
                           appraisers. In determining fair market value, neither
                           the Board nor any appraiser shall take into account
                           (x) the value assigned to the Nextera Class A Shares
                           in connection with the Purchase Agreement or (y) any
                           discount for a minority interest.

         The Escrow Shares delivered to Nextera in satisfaction of a claim shall
be allocated among the SC Shareholders so as to reduce each SC Shareholder's
interest in the remaining 
<PAGE>   5
                                     - 5 -


Escrow Shares in proportion to their respective ownership percentages as set
forth on Exhibit A hereto. Notwithstanding the foregoing, (i) any claim that is
an Individual Claim (as defined in the Purchase Agreement) shall be satisfied by
reduction of the interest in the Escrow Deposit of the SC Shareholder who
committed fraud or who made the representation, warranty or covenant from which
the Individual Claim arose and no other SC Shareholder shall have any liability
therefor hereunder and (ii) the satisfaction of one or more Individual Claims as
describe in clause (i) shall not increase the proportion of any subsequent claim
for which any SC Shareholder would have been responsible absent such prior
satisfaction of such Individual Claims. In the event that the Escrow Agent must
make payment with a number of Shares less than or different from the number of
Shares represented by a certificate in the Escrow Deposit, the Escrow Agent
shall surrender such certificate to Nextera and Nextera shall issue to the
Escrow Agent certificates of Nextera Class A Shares identical in form but for
the number of Shares as necessary to allow for proper payment of the claim so
long as the number of Shares of the new certificates plus the amount of Shares
used to satisfy such claim shall be equivalent to the total number of Shares
covered by the surrendered certificate.

4.       Disputed Claims.

         (a)      If the Escrow Representative shall dispute an indemnification
                  claim of Nextera as above provided, the Escrow Agent shall set
                  aside a portion of the Escrow Deposit sufficient to pay said
                  claim in full as reasonably determined by Nextera in good
                  faith (the "Set Aside Amount"). Nextera shall notify the
                  Escrow Agent in writing of the Set Aside Amount. If Nextera
                  notifies the Escrow Agent in writing that it has made
                  out-of-pocket expenditures in connection with any such
                  disputed claim, and provides paid receipts for such
                  expenditures, in addition to expenditures included in the Set
                  Aside Amount, an amount equal to such additional expenditures
                  shall be added to the Set Aside Amount. The appropriate number
                  of Escrow Shares in the Set Aside Amount shall be determined
                  by the procedure described in Section  3(b)(ii) above.

         (b)      If the disputed indemnification claim has not been resolved or
                  compromised within sixty (60) days after the Escrow Agent's
                  receipt of the Escrow Representative's notice of dispute of
                  the same, or in the event of a third-party claim or suit,
                  within fifteen (15) days after its resolution or compromise,
                  said indemnification claim shall be referred to the American
                  Arbitration Association, to be settled by binding arbitration
                  in New York, New York, in accordance with the commercial
                  arbitration rules of the Association. The fees and expenses of
                  the arbitrator shall be borne equally by the SC Shareholders
                  on the one hand and Canadian Buyer and Nextera on the other.
                  In no event shall the Escrow Agent be responsible for any fee
                  or expense of any party to any arbitration proceeding. The
                  determination of the arbitrator as to the amount, if any, of
                  the indemnification claim which is properly allowable shall be
                  conclusive and binding upon the parties hereto and judgment
                  may be entered thereon in any court having jurisdiction
                  thereof, including, without limitation, any court in the State
                  of New York. The arbitrator shall have the authority in its
                  discretion to award to the prevailing party reasonable costs
                  and 
<PAGE>   6
                                     - 6 -


                  expenses including attorney's fees and the cost of
                  arbitration. The Escrow Agent shall use its best efforts to
                  make payment of such claim, as and to the extent allowed, to
                  Nextera out of the Set Aside Amount (or if insufficient, out
                  of the Escrow Deposit) within three (3) business days
                  following the Escrow Agent's receipt of said determination or
                  as soon thereafter as possible.

         (c)      Notwithstanding Section  4(b), if a disputed indemnification
                  claim has not been resolved or compromised as of the
                  Termination Date (as hereinafter defined), and such claim does
                  not involve a third-party claim or suit, Nextera and the
                  Escrow Representative shall continue to negotiate in good
                  faith a settlement of such claims for a period of ten (10)
                  days after the Termination Date. If, after the expiration of
                  such ten-day period, such indemnification claim still has not
                  been resolved or compromised, such claim shall be settled in
                  accordance with the arbitration provisions set forth in
                  Section  4(b).

         (d)      It is understood and agreed that should any dispute arise
                  under this Section  4, the Escrow Agent, upon receipt of
                  written notice of such dispute or claim by the Escrow
                  Representative, is authorized and directed to retain in its
                  possession without liability to anyone, the Set Aside Amount
                  relating to such dispute plus any expenditures of Nextera made
                  pursuant to Section  4(a) until such dispute shall have been
                  settled pursuant to this Section  4. The Escrow Agent may, but
                  shall be under no duty whatsoever to, institute or defend any
                  legal proceedings which relate to the Escrow Deposit.

         (e)      In connection with the resolution of a disputed
                  indemnification claim, the arbitrator may award, in its
                  discretion, to the SC Shareholders interest on the amount by
                  which the Set Aside Amount exceeds the amount which the
                  arbitrator determined would have been a reasonable Set Aside
                  Amount, computed from the Termination Date to the date such
                  Set Aside Amount is released from escrow if the arbitrator
                  determines that (i) Nextera had no reasonable basis for making
                  the indemnification claim or (ii) the Set Aside Amount as
                  determined by Nextera had no reasonable relation to the amount
                  of the claim. The arbitrator may not award interest under this
                  Section  4(e) if Nextera's claim is occasioned by, or the Set
                  Aside Amount corresponds to the amount of, a third-party claim
                  regardless of the merits of such third-party claim.

5.       Exchange of Escrow Shares. Pursuant to the provisions attaching to the
         Exchangeable Shares and the provisions under the Share Exchange
         Agreement (the "Share Exchange Agreement"), SC Shareholders may
         exchange their Exchangeable Shares for Nextera Class A Shares, or such
         other Shares or other security (the "Exchanged Securities") as provided
         for in the Share Exchange Agreement. In the event of an exchange during
         the term of this Agreement, the remaining Escrow Shares shall be
         released from escrow under this Agreement and an appropriate number of
         Exchanged Securities shall be delivered to the Escrow Agent in
         substitution for the Escrow Shares. Following such an exchange, all
         references to Escrow Shares in this Agreement shall be deemed to
         include such Exchanged 
<PAGE>   7
                                     - 7 -


         Securities. The Escrow Agent shall follow the joint written instruction
         of Nextera and the Escrow Representative in carrying out the provisions
         of this Section  5.

6.       Termination. This Agreement shall terminate on the date that the Escrow
         Deposit is reduced to zero as the result of payments by the Escrow
         Agent to Nextera in accordance with the provisions of Section  3 or
         Section 4. If, however, the Escrow Deposit has not been reduced to zero
         as of the date that is eighteen (18) months following the date of this
         Agreement (the "Termination Date") and there are no outstanding
         indemnification claims on the Termination Date of which Escrow Agent
         has received notice hereunder, the Escrow Agent shall distribute the
         amount remaining in the Escrow Deposit to the SC Shareholders in
         accordance with their respective ownership percentages as set forth on
         Exhibit A hereto. After such payment this Agreement shall terminate;
         otherwise this Agreement shall continue in effect until all
         indemnification claims Nextera has made pursuant to Section 3 hereof on
         or prior to the Termination Date shall have been disposed of. As of the
         Termination Date, an amount of the Escrow Deposit adequate to cover all
         disputed and undisputed claims made by Nextera pursuant to Section  3
         hereof will be held by the Escrow Agent (with the number of Escrow
         Shares, if any, to be retained determined in accordance with Section
         3(b)(ii)) and the Escrow Agent shall distribute on the Termination Date
         the balance, if any, of the Escrow Deposit to the SC Shareholders in
         accordance with their respective ownership percentages as set forth on
         Exhibit A hereto. At such time as all remaining indemnification claims
         hereunder have been resolved and the Escrow Agent has received a
         written notice executed by Nextera and the Escrow Representative, or
         notification of a determination of an arbitrator pursuant to Section
         4(b), to that effect and any amounts to be distributed to Nextera in
         connection therewith have been so distributed, the Escrow Agent shall
         distribute the remaining Escrow Deposit, if any, to the SC Shareholders
         in accordance with their respective ownership percentages as set forth
         on Exhibit A hereto.

7.       The Escrow Agent.

         (a)      Direction from Nextera and Escrow Representative.
                  Notwithstanding anything herein to the contrary, the Escrow
                  Agent shall promptly dispose of all or any part of the Escrow
                  Deposit as directed by a writing signed by Nextera and Escrow
                  Representative.

         (b)      Reliance by Escrow Agent; Liability of Escrow Agent. Except
                  with respect to capitalized terms used herein and defined in
                  the Purchase Agreement or the Exchange Agreement, the Escrow
                  Agent will not be subject to, or be obliged to recognize, any
                  other agreement between the parties hereto or directions or
                  instructions not specifically set forth as provided for
                  herein. The Escrow Agent will not make any payment or
                  disbursement from or out of the Escrow Deposit that is not
                  expressly authorized pursuant to this Agreement. The Escrow
                  Agent undertakes to perform only such duties as are expressly
                  set forth herein. The Escrow Agent may rely and shall be
                  protected in acting or refraining from acting upon any written
                  notice, instruction or request furnished to it hereunder and
                  believed by it to be genuine and to have been signed or
                  presented by the proper party or parties. The Escrow Agent
                  shall be 
<PAGE>   8
                                     - 8 -


                  under no duty to inquire into or investigate the validity,
                  accuracy or content of any such document. The Escrow Agent
                  shall have no duty to solicit any payment which may be due it
                  hereunder. The Escrow Agent shall not be liable for any action
                  taken or omitted by it in good faith unless a court of
                  competent jurisdiction determines that the Escrow Agent's
                  gross negligence and willful misconduct was the primary cause
                  of any loss to Canadian Buyer, Nextera or the SC Shareholders.
                  In the administration of the Escrow Deposit hereunder, the
                  Escrow Agent may execute any of its powers and perform its
                  duties hereunder directly or through agents or attorneys and
                  may consult with counsel, accountants and other skilled
                  persons to be selected and retained by it. The Escrow Agent
                  shall not be liable for anything done, suffered or omitted in
                  good faith by it in accordance with the advice or opinion of
                  any such counsel, accountants or other skilled persons.
                  Canadian Buyer, Nextera and the SC Shareholders jointly and
                  severally hereby agree to indemnify and hold the Escrow Agent
                  and its directors, officers, agents and employees
                  (collectively, the "Indemnities") harmless from and against
                  any and all claims, liabilities, losses, damages, fines,
                  penalties, and expenses, including out-of-pocket and
                  incidental expenses and legal fees and expenses ("Losses")
                  that may be imposed on, incurred by, or asserted against the
                  Indemnitees or any of them for following any instructions or
                  other directions upon which the Escrow Agent is authorized to
                  rely pursuant to the terms of this Agreement. In addition to
                  and not in limitation of the immediately preceding sentence,
                  Canadian Buyer, Nextera and the SC Shareholders also agree
                  jointly and severally to indemnify and hold the Indemnitees
                  and each of them harmless from and against any and all Losses
                  that may be imposed on, incurred by, or asserted against the
                  Indemnitees or any of them in connection with or arising out
                  of Escrow Agent's performance under this Agreement, provided
                  the Indemnitees have not acted with gross negligence or
                  engaged in willful misconduct. Anything in this Agreement to
                  the contrary notwithstanding, in no event shall the Escrow
                  Agent be liable for special, indirect or consequential loss or
                  damage of any kind whatsoever (including but not limited to
                  lost profits). As between Canadian Buyer and Nextera on the
                  one hand and the SC Shareholders on the other, each shall bear
                  equally the indemnification obligations set forth in this
                  Section  7(b). The provisions of this Section  7(b) shall
                  survive the termination of this Agreement and the resignation
                  or removal of the Escrow Agent for any reason.

         (c)      Fees and Expenses of the Escrow Agent. All fees of the Escrow
                  Agent for its services hereunder, together with any expenses
                  reasonably incurred by the Escrow Agent in connection with
                  this Agreement, shall be paid by Canadian Buyer. All fees of
                  the Escrow Agent in connection herewith shall be due from the
                  parties upon receipt of an invoice from the Escrow Agent
                  delivered to Nextera.

         (d)      Resignation and Removal of Escrow Agent; Successor Escrow
                  Agent.

                  (i)      The Escrow Agent may resign from its duties hereunder
                           by giving each of the parties hereto not less than
                           thirty (30) days prior written 
<PAGE>   9
                                     - 9 -


                           notice of the effective date of such resignation
                           (which effective date shall be at least thirty (30)
                           days after the date such notice is given). In
                           addition, the Escrow Agent may be removed and
                           replaced on a date designated in a written instrument
                           signed by Nextera and the Escrow Representative and
                           delivered to the Escrow Agent. The parties hereto
                           intend that a successor escrow agent mutually
                           acceptable to the Escrow Representative and Nextera
                           will be appointed to fulfill the duties of the Escrow
                           Agent hereunder for the remaining term of this
                           Agreement in the event of the Escrow Agent's
                           resignation or removal. Upon the effective date of
                           such resignation or removal, the Escrow Agent shall
                           deliver the property comprising the Escrow Deposit to
                           such successor escrow agent, together with an
                           accounting of the investments held by it and all
                           transactions related to this Agreement, including any
                           distributions made and such records maintained by the
                           Escrow Agent in connection with its duties hereunder
                           and other information with respect to the Escrow
                           Deposit as such successor may reasonably request. If
                           on or before the effective date of such resignation
                           or removal, a successor escrow agent has not been
                           appointed, the Escrow Agent will thereupon deposit
                           the Escrow Deposit into the registry of a court of
                           competent jurisdiction.

         Upon written acknowledgment by a successor escrow agent appointed in
accordance with this Section  7(d)(i) of its agreement to serve as escrow agent
hereunder and the receipt of the property then comprising the Escrow Deposit,
the Escrow Agent shall be fully released and relieved of all duties,
responsibilities and obligations under this Agreement, except for those arising
under the last sentence of Section  7(b) of this Agreement, and such successor
escrow agent shall for all purposes hereof be the Escrow Agent.

                  (ii)     Any corporation, association or other entity into
                           which the Escrow Agent may be converted or merged, or
                           with which it may be consolidated, or to which it may
                           sell or otherwise transfer all or substantially all
                           of its corporate trust business, or any corporation,
                           association or other entity resulting from any such
                           merger, conversion, consolidation, sale or other
                           transfer, shall, ipso facto, be and become successor
                           Escrow Agent hereunder, vested with all of the
                           powers, discretions, immunities, privileges and all
                           other matters as was its predecessor, without the
                           execution or filing of any instrument or any further
                           act on the part or any of the parties hereto,
                           anything herein to the contrary notwithstanding.

8.       Voting of Escrow Shares. So long as any Escrow Shares are retained by
         the Escrow Agent, the SC Shareholders in accordance with their
         respective ownership percentages as set forth on Exhibit A hereto,
         shall be entitled to exercise the voting power, if any, with respect to
         in the Escrow Shares, in accordance with their respective ownership
         percentages as set forth on Exhibit A hereto.

9.       Governing Law. IT IS THE PARTIES' INTENT THAT THIS AGREEMENT SHALL BE

12.      Certification of Tax Identification Number. The parties hereto agree to
         provide the Escrow Agent with a certified tax identification number by
         signing and returning a Form W-9 (or Form W-8, in the case of non-U.S.
         persons) to the Escrow Agent prior to the date on which any income
         earned on the investment of the Escrow Deposit is credited to the
         Escrow Deposit. The parties hereto understand that, in the event their
         tax identification numbers are not certified to the Escrow Agent, the
         Internal Revenue Code, as amended from time to time, may require
         withholding of a portion of any interest or other income earned on the
         investment of the Escrow Deposit.

13.      Force Majeure. Neither Canadian Buyer, Nextera, the SC Shareholders nor
         the Escrow Agent shall be responsible for delays or failures in
         performance under this Agreement resulting from acts beyond its
         control. Such acts shall include but not be limited to acts of God,
         strikes, lockouts, riots, acts of war, epidemics, governmental
         regulations superimposed after the fact, fire, communication line
         failures, computer viruses, power failures, earthquakes or other
         disasters.

14.      Modifications. This Agreement may not be altered or modified nor may
         any condition or covenant set forth herein be waived, without the
         express written consent of the parties hereto, provided that, except as
         specifically provided by Section  1(b) above, the Escrow Representative
         shall be authorized to agree to any amendment, modification or waiver
         on behalf of the SC Shareholders which shall be valid and binding upon
         the SC Shareholders. No course of conduct shall constitute a waiver of
         any of the terms and conditions of this Escrow Agreement, unless such
         waiver is specified in writing, and then only to the extent so
         specified. A waiver of any of the terms and conditions of this Escrow
         Agreement on one occasion shall not constitute a waiver of the other
         terms of this Escrow Agreement, or of such terms and conditions on any
         other occasion.

15.      Reproduction of Documents. This Agreement and all documents relating
         thereto, including, without limitation, (a) consents, waivers and
         modifications which may hereafter be executed, and (b) certificates and
         other information previously or hereafter furnished, may be reproduced
         by a photographic, photostatic, microfilm, optical disk, micro-card,
         miniature photographic or other similar process. The parties agree that
         any such reproduction shall be admissible in evidence as the original
         itself in any judicial or administrative proceeding, whether or not the
         original is in existence and whether or not such reproduction was made
         by a party in the regular course of business, and that any enlargement,
         facsimile or further reproduction of such reproduction shall likewise
         be admissible in evidence.

16.      Permitted Transfers. The Parties hereby acknowledge that from the date
         hereof, each SC Shareholder shall be permitted to transfer his
         beneficial interest in the Escrow Shares to an individual holding
         company ("HOLDCO") and that upon such a transfer, such SC Shareholder
         and his Holdco will continue to be jointly and severally liable for the
         obligations of such SC Shareholder under the Purchase Agreement and
         hereunder. The certificates representing the Escrow Shares shall be
         deemed to be in the name of the Holdco of the respective SC
         Shareholder. In the event of a transfer of the beneficial interest in
         the Escrow Shares to the Holdcos, all of the terms and conditions of
         this Agreement shall apply to the Holdcos, as if the Holdcos were the
         SC Shareholders mutatis mutandis. The SC Shareholders will promptly
         notify the Escrow Agent upon a transfer of any beneficial interest in
         the Escrow Shares to Holdco and provide the Escrow Agent with evidence
         of such a transfer.

                                   ARTICLE I.

                    EXCHANGE OF THE SHARES AND CONSIDERATION.

          1.1. Shares Being Exchanged; Consideration.

               (a) At the Closing (as hereinafter defined), and subject to the
terms and conditions of this Agreement, each U.S. Shareholder shall assign,
transfer and deliver to Newco all of its Shares in the manner described in
Section 1.3. Subject to the terms and conditions of this Agreement, and in
consideration of the assignment and delivery of the Shares to Newco, Newco shall
issue to the U.S. Shareholders and/or their Permitted Assignees (as defined in
Section 4.5), and the U.S. Shareholders and/or their Permitted Assignees shall,
in the aggregate, acquire and accept from Newco, that certain number of shares
of Newco Class A Stock which represents the identical percentage of the total
issued and outstanding common stock of Newco following the Incorporation
Transaction as that percentage of the total issued and outstanding membership
interest in Nextera which General Partner and Limited Partner own immediately
prior to the Incorporation Transaction (including the Class A Common Units held
pursuant to the Escrow Agreement) (the "New Stock").

              Contemporaneous with the exchange of Shares by the U.S.
Shareholders for Newco Class A Stock, each member of Nextera other than General
Partner and Limited Partner shall contribute his membership interest in Nextera
in exchange for that certain number of shares of Newco common stock which
represents the identical percentage of the total issued and outstanding common
stock of Newco following the Incorporation Transaction as that percentage of the
total issued and outstanding membership interest in Nextera which such member
may own immediately prior to the Incorporation Transaction. Each member shall
receive Newco Class A Stock and Class B Common Stock of Newco ("Newco Class B
Stock") in exchange, and in proportion to, the Nextera Class A Units and Class B
Common Units of Nextera ("Nextera





                                       2

Class B Units") which he exchanges. The rights and preferences of the holders of
Newco Class A Stock and Newco Class B Stock shall be identical, except that the
holders of Newco Class A Stock are entitled to one vote per share and the
holders of Newco Class B Stock are entitled to ten votes per share on all
matters voted on by the stockholders of the Company. Each share of Newco Class B
Stock will be convertible into one share of Newco Class A Stock as described on
Schedule 3.2.

               (b) To implement the foregoing, at the Closing, Newco shall issue
in the name of each U.S. Shareholder a number of shares of Newco Class A Stock
equal to the product of (i) the aggregate number of shares of Newco Class A
Stock to be issued to the U.S. Shareholders pursuant to Section 1.1(a) and (ii)
such U.S. Shareholder's combined ownership percentage set forth on Exhibit A
hereto (with respect to any U.S. Shareholder, such "U.S. Shareholder's
Percentage"). Each U.S. Shareholder shall be issued two certificates
representing the shares of Newco Class A Stock to which such U.S. Shareholder is
entitled pursuant to the immediately preceding sentence (a "U.S. Shareholder's
Total Newco Shares") as follows: the first for a number of shares of Newco Class
A Stock which is equal to the product of (A) the number of shares of Newco Class
A Stock which represents the identical percentage of the total issued and
outstanding Newco Class A Stock following the Incorporation Transaction as the
percentage of issued and outstanding Nextera Class A Units held pursuant to that
certain Escrow Agreement dated as of the date hereof by and among Nextera, the
Partnership, General Partner, Limited Partner, the U.S. Shareholders and Chase
Manhattan National Trust Company (the "U.S. Escrow Agreement") immediately prior
to the Incorporation Transaction (the "Total Escrow Shares") and (B) such U.S.
Shareholder's Percentage (the number of shares resulting from such product being
referred to as a "U.S. Shareholder's Escrow Shares"), and the second for the
balance of such U.S. Shareholder's Total Newco Shares (a "U.S. Shareholder's
Non-Escrow Shares"). Newco shall deliver the certificates representing each U.S.
Shareholder's Escrow Shares to the Escrow Agent for deposit into escrow pursuant
to the U.S. Escrow Agreement and each U.S. Shareholder shall deliver to the
Shareholder Representative (as hereinafter defined) a stock power, duly executed
in blank with respect to such U.S. Shareholder's Escrow Shares, for delivery by
the Shareholder Representative to the Escrow Agent. Newco shall deliver the
certificates representing each U.S. Shareholder's Non-Escrow Shares to the
Shareholder Representative for delivery to such U.S. Shareholder.

          1.2. Closing. The Closing of the transaction contemplated by this
Agreement (the "Closing") shall take place at a mutually agreeable location in
New York, New York on or before January 1, 1999; provided, however, that Nextera
may extend the closing at its option to no later than March 31, 1999 if it in
good faith expects to complete an initial public offering of the capital stock
of Newco within such extended period and delivers to the Shareholder
Representative written notice to such effect on or before December 31, 1998. The
date of the Closing is referred to hereinafter as the "Closing Date."

          1.3. Surrender of Certificates.

               (a) As of the date hereof, the U.S. Shareholders have delivered
to the Shareholder Representative (who shall have presented to Nextera for
review) each certificate


                                       3

<PAGE>   7

representing Shares with assignments duly executed in blank (or the equivalent)
and such other documents as may reasonably be required by Nextera in order to
effect as of the Closing a valid transfer of such Shares by the U.S.
Shareholders, free and clear of any and all liens, encumbrances, charges or
claims. At the Closing, the Shareholder Representative shall deliver the
certificates and assignments representing Shares to Newco and Newco shall
deliver certificates representing the Newco Class A Stock to the Shareholder
Representative and/or the Escrow Agent as provided in Section 1.1.

               (b) There shall be no obligation to deliver the Newco Class A
Stock in respect of any Shares until (and then only to the extent that) the
holder thereof validly surrenders his certificate or certificates representing
the Shares, or, in lieu thereof, delivers to Newco an appropriate affidavit of
loss and an indemnity agreement as may be required in any such case by Newco in
its reasonable discretion.

               (c) If any shares of Newco Class A Stock are to be issued in a
name other than that in which the certificate for Shares surrendered for
exchange is registered, it shall be a condition to the payment that the
certificate so surrendered shall be properly endorsed or otherwise in proper
form for transfer and that the person requesting the payment shall either (i)
pay to Newco any transfer or other taxes required by reason of the issuance of
Newco Class A Stock to a person other than the registered holder of the
certificate surrendered or (ii) establish to the satisfaction of Newco that such
taxes have been paid or are not payable.

          1.4. No Further Rights. At and after the Closing, each holder of a
certificate that represented Shares immediately prior to the Closing shall cease
to have any rights as a shareholder of General Partner or Limited Partner. This
Section 1.4 shall not, however, impair rights otherwise expressly provided in
this Agreement.

          1.5. Canadian Exchangeable Shares. At and after the Closing, each
certificate that represented Exchangeable Shares (including the Exchangeable
Shares deposited pursuant to that certain Escrow Agreement (the "Canadian Escrow
Agreement") by and among Nextera, Sibson Acquisition Co., the Canadian
Shareholders and Chase Manhattan Trust Company) shall cease to be exchangeable
for Nextera Class A Units and instead shall be exchangeable only for Newco Class
A Stock. Each Exchangeable Share shall be exchangeable for that certain number
of shares of Newco Class A Stock which represents the identical percentage of
the total issued and outstanding common stock of Newco following the
Incorporation Transaction (immediately after giving effect to the exchange of
Shares for shares of Newco Class A Stock by the U.S. Shareholders and the
exchange of membership interests by certain of the members of Nextera for shares
of Newco Class A Stock all as contemplated by Section 1.1 hereof) as that
percentage of the total issued and outstanding membership interest in Nextera
which such Exchangeable Share was exchangeable for immediately prior to the
Incorporation Transaction.

          1.6. Shareholder Representative. The Shareholders hereby appoint the
Partnership, and, upon conversion of the Partnership to a limited liability
company as provided in Section 4.4, such limited liability company to serve as
the exclusive representative of the Shareholders with respect to this Agreement
(the "Shareholder Representative") and the




                                       4
<PAGE>   8

Partnership, on behalf of itself and its successors and assigns, hereby accepts
such appointment. If, for any reason, the Shareholder Representative shall be
either unable or unwilling to serve, a successor Shareholder Representative
shall be appointed by written consent of the Shareholders and all references to
the Shareholder Representative shall be deemed to include such successor. Each
Shareholder whose signature appears below expressly agrees that this Agreement
may be amended or modified, and compliance with any condition or covenant may be
waived without the consent of, or execution thereof by, such Shareholder if the
Shareholder Representative agrees to such amendment or modification or grants
such waiver, in each case by a writing duly and validly executed by the
Shareholder Representative as provided in Section 8.10; provided, however, that
the Shareholder Representative will not enter into any such amendment or
modification or waive any condition or covenant that materially and adversely
affects any Shareholder differently than all other Shareholders affected thereby
without the consent of such Shareholder.

          1.7. Incorporation Transaction.

               (a) KE and the other Members (as defined in the Second Amended
and Restated Limited Liability Company Agreement of Nextera, dated as of May 1,
1998, as amended (the "Nextera Operating Agreement"), a copy of which has been
attached as Exhibit M to the Purchase Agreement), shall effect the Incorporation
Transaction pursuant to Section 11 of the First Amendment to the Nextera
Operating Agreement (the "First Amendment").

               (b) The Members, other than General Partner and Limited Partner,
shall be required to contribute their Units to Newco in exchange for the stock
of Newco in accordance with Section 11 of the First Amendment. The amount and
class of such stock issued to each Member shall correspond to the class and
percentage membership interest of such Member immediately prior to the
Incorporation Transaction. Subject to the terms and conditions of this
Agreement, General Partner and Limited Partner shall not contribute their
Nextera Class A Units. In order to implement the foregoing, Nextera has gathered
from its members the certificates representing all of the issued and outstanding
membership interests in Nextera (including certificates representing membership
interests held under escrow agreements to which Nextera is a party) with
assignments duly executed in blank (or the equivalent) and any other documents
as may be reasonably necessary to effect as of the Closing a valid transfer of
such membership interests free and clear of all liens, encumbrances, charges or
claims.

               (c) The Stockholders Agreement attached hereto as Exhibit C (the
"Stockholders Agreement") shall be executed as of the date hereof by Nextera,
Newco, the Members, and the Shareholders, shall become effective upon the
Closing and shall govern the actions of the stockholders of Newco with respect
to the matters set forth therein following the Incorporation Transaction.

               (c) Prior to the liquidation or conversion of the Partnership as

(as hereinafter defined) which recognize such status.




                                       7

Returns are true, correct, and complete in all material respects.

               (d) General Partner and Limited Partner have timely paid all

interests in General Partner or Limited Partner, except liens for Taxes not yet

               (f) No Tax Returns of General Partner or Limited Partner have
been audited by the relevant taxing authority. No deficiency for any Taxes has
been proposed, asserted or assessed against General Partner or Limited Partner
that has not been paid in full. There are no outstanding waivers, extensions, or
comparable consents regarding the application of the statute of limitations with
respect to any Taxes or Tax Returns of General Partner or Limited Partner

waivers, extensions, or comparable consents.

               (g) No audit or other proceeding by any federal, state, local or
foreign court, governmental, regulatory, administrative or similar authority is
presently pending with respect to any Taxes or Tax Return of General Partner or
Limited Partner, and neither General Partner nor any Limited Partner has
received written notice of any pending audits or proceedings.

               (h) Neither General Partner nor any Limited Partner has received
a ruling from any taxing authority or signed an agreement with any taxing

and the manner prescribed by law, paid over to the proper governmental
authorities all amounts so withheld.

<PAGE>   12

               (k) No power of attorney granted by General Partner or Limited
Partner with respect to any Taxes is currently in force.

               (l) There is no expectation that any taxing authority may claim
or assess any material amount of Taxes payable by General Partner or Limited
Partner for any period ending on or prior to the Closing Date and there are no
facts of which General Partner or Limited Partner or the Shareholders are aware

Partner or Limited Partner from a taxing authority in a jurisdiction where
General Partner or Limited Partner does not pay Taxes or file Tax Returns that
General Partner or Limited Partner is or may be subject to Taxes assessed by
such jurisdiction, and, to the knowledge of such Shareholder, no such claim has
been threatened by a taxing authority.

               (o) General Partner and Limited Partner are United States persons
within the meaning of the Code.

          2.7. Experience; Accredited Investor. Such Shareholder has substantial
experience in evaluating and investing in private placement transactions of
securities in companies similar to Newco so that he is capable of evaluating the
merits and risks of acquiring the Newco Class A Stock to be issued to such
Shareholder and has the capacity to protect his own interests. Such Shareholder
must bear the economic risk of holding the Newco Class A Stock (when issued)
indefinitely unless such securities are registered pursuant to the Securities
Act of 1933, as amended (the "Securities Act"), or an exemption from
registration is available for the disposition thereof. Such Shareholder
understands that there is no assurance that any exemption from registration
under the Securities Act will be available. Such Shareholder is an "accredited
investor" as defined in Rule 501 under the Securities Act.

          2.8. Investment. Such Shareholder is acquiring the Newco Class A Stock
for his own account for investment only, and not with the view to, or for resale
in connection with, any distribution thereof. It understands that the Newco
Class A Stock to be acquired has not been, and will not be, registered under the
Securities Act by reason of a specific exemption from the registration
provisions of the Securities Act, the availability of which depends upon, among
other things, the bona fide nature of the investment intent and the accuracy of
the Shareholder's representations as expressed herein.




                                       9
<PAGE>   13


          2.9. No Public Market. Such Shareholder understands that no public
market now exists for any of the securities issued by Nextera or Newco and that
Nextera has not made any assurances that a public market will ever exist for
such securities.

          2.10. Access to Data; Incorporation Transaction. Such Shareholder has
received and read the Nextera business plan and financial statements and has had
an opportunity to discuss Nextera's business, management and financial affairs
and the Incorporation Transaction with its management. Such Shareholder has also
had an opportunity to ask questions of and receive answers from officers of
Nextera regarding the terms and conditions of acquiring Newco Class A Stock in
the Incorporation Transaction and pursuant to this Agreement, which questions
were answered to such Shareholder's satisfaction.

          2.11. Residence. The residence of such Shareholder in which his
investment decision was made is set forth next to such Shareholder's name on the
signature page hereto.

                                  ARTICLE III.

                   REPRESENTATIONS AND WARRANTIES OF NEXTERA.

          As a material inducement to the Shareholders to enter into this
Agreement and consummate the transactions contemplated hereby, Nextera hereby
makes to the Shareholders each of the representations and warranties set forth
in this Article III.

          3.1. Organization and Qualification. Newco is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware with corporate power and authority to own or lease its properties and
to conduct its business in the manner and in the places where such properties
are owned or leased or such business is currently conducted or proposed to be
conducted as a result of the transactions contemplated by this Agreement. Copies
of the Certificate of Incorporation and Bylaws of Newco and all amendments
thereto shall be delivered to the Shareholder Representative not less than ten
(10) business days before the Closing and will be accurate and complete as of
the Closing. As of the Closing, Newco will not be in violation of any term of
its Certificate of Incorporation or Bylaws.

          3.2. Capitalization and Beneficial Ownership of Newco. The Newco Class
A Stock and Newco Class B Stock to be issued to the Shareholders pursuant to
Article I will be duly and validly issued, and outstanding, and fully paid and
non-assessable. As of the Closing the rights and preferences of the holders of
Newco Class A Stock and Newco Class B Stock shall be identical, except that the
holders of Newco Class A Stock will be entitled to one vote per share and the
holders of Newco Class B Stock will be entitled to ten votes per share on all
matters voted on by the stockholders of the Company. Each share of Newco Class B
Stock will be convertible into one share of Newco Class A Stock as described on
Schedule 3.2 . Schedule 3.2 sets forth all of the issued and outstanding
membership interests of Nextera and Buyer on the date hereof and on the Closing
Date (assuming consummation of the transactions contemplated hereby, including,
in the case of Nextera, the sale of Nextera Class A Units and Nextera Class B
Units under the Employment Agreements (as defined in the Purchase Agreement)).

<PAGE>   14


          The authorized capital stock of Newco will consist of such number of
shares of Newco Class A Stock and Newco Class B Stock as will be set forth on a
revised Schedule 3.2 to be provided at least ten (10) business days prior to the
Closing to the Shareholder Representative, which revised Schedule 3.2 will also
set forth the number of such shares that will be outstanding as of the Closing
assuming the consummation of the transactions contemplated hereby. Other than
options granted under the 1998 Equity Participation Plan of Newco (a true and
complete copy of which will be provided prior to the Closing to the Shareholder
Representative) or as set forth in the Stockholders Agreement or on a revised
Schedule 3.2 to be provided prior to the Closing to the Shareholder
Representative, there will be no outstanding options, warrants, rights,
commitments, preemptive rights or agreements of any kind for the issuance or
sale of, or outstanding securities convertible into, any additional equity of
any class of Newco. As of the Closing, none of Newco's capital stock will have
been issued in violation of any federal or state law. Except as provided in the
Stockholders Agreement, there will be no voting trusts, voting agreements,
proxies or other agreements, instruments or undertakings with respect to the
voting of the capital stock of Newco to which Newco or, to the knowledge of
Newco, any of the Members are or will be a party or by which their property is
or will be bound.

          3.3. Authority of Nextera. Nextera has full authority, power and
capacity to enter into this Agreement and each agreement, document and
instrument to be executed and delivered by Nextera pursuant to this Agreement
and to carry out the transactions contemplated hereby and thereby. This
Agreement and each agreement, document and instrument executed and delivered by
Nextera pursuant to this Agreement constitutes a valid and binding obligation of
Nextera, enforceable in accordance with their respective terms (assuming the due
authorization, execution and delivery by the other parties thereto), subject to
the effect of any applicable bankruptcy, reorganization, insolvency, moratorium
or similar laws affecting creditors' rights generally and subject to the effect
of general principles of equity, including, without limitation, the possible
unavailability of specific performance or injunctive relief, regardless of
whether considered in a proceeding in equity or at law. No other limited
liability company proceedings on the part of Nextera are necessary to authorize
this Agreement and the transactions contemplated hereby. The execution, delivery
and performance by Nextera of this Agreement and each such agreement, document
and instrument:

                    (i) does not and will not violate any provision of any laws
          of the United States or any state or other jurisdiction applicable to
          Nextera, or require Nextera to obtain any approval, consent or waiver
          from, or make any filing with, any person or entity (governmental or
          otherwise) other than any such approval, consent or waiver of or
          filing with respect to which the failure to so obtain will not have a
          material adverse effect or result in a change in the condition
          (financial or other), business, results of operations, prospects,
          assets, Liabilities (as hereinafter defined) or operations of Nextera
          and its Subsidiaries (as defined in the Purchase Agreement) taken as a
          whole or on the ability of Nextera to consummate the transactions
          contemplated hereby, or any event or condition which would, with the
          passage of time, have such effect; and




                                       11
<PAGE>   15

                           (ii) does not and will not result in (a) a breach of,
         constitute a default under, accelerate any obligation under, or give
         rise to a right of termination of, any indenture or loan or credit
         agreement or any other agreement, contract, instrument, mortgage, lien,
         lease, permit, authorization, order, writ, judgment, injunction,
         decree, determination or arbitration award to which Nextera is a party
         or by which the property of Nextera is bound or affected, or (b) the
         creation or imposition of any mortgage, pledge, lien, security interest
         or other charge or encumbrance on any of the assets or on the equity of
         Nextera, except, in the case of clause (a) for such breaches, defaults,
         accelerations or terminations as would not, individually or in the
         aggregate, have a material adverse effect or result in a change in the
         condition (financial or other), business, results of operations,
         prospects, assets, Liabilities or operations of Nextera and its
         Subsidiaries (as defined in the Purchase Agreement) taken as a whole or
         on the ability of Nextera to consummate the transactions contemplated
         hereby, or any event or condition which would, with the passage of
         time, have such effect.

          3.4. Authority of Newco. Newco has full authority, power and capacity
to enter into this Agreement and each agreement, document and instrument to be
executed and delivered by Newco pursuant to this Agreement and to carry out the
transactions contemplated hereby and thereby. This Agreement and each agreement,
document and instrument executed and delivered by Newco pursuant to this
Agreement constitutes a valid and binding obligation of Newco, enforceable in
accordance with their respective terms (assuming the due authorization,
execution and delivery by the other parties thereto), subject to the effect of
any applicable bankruptcy, reorganization, insolvency, moratorium or similar
laws affecting creditors' rights generally and subject to the effect of general
principles of equity, including, without limitation, the possible unavailability
of specific performance or injunctive relief, regardless of whether considered
in a proceeding in equity or at law. Except as set forth on Schedule 3.4, no
other corporate proceedings on the part of Newco are necessary to authorize this
Agreement and the transactions contemplated hereby. The execution, delivery and
performance by Newco of this Agreement and each such agreement, document and
instrument:

                    (i) will not violate any provision of any laws of the United
          States or any state or other jurisdiction applicable to Newco, or
          require Newco to obtain any approval, consent or waiver from, or make
          any filing with, any person or entity (governmental or otherwise),
          other than any such approval, consent or waiver of or filing with
          respect to which the failure to so obtain will not have a material
          adverse effect or result in a change in the condition (financial or
          other), business, results of operations, prospects, assets,
          Liabilities or operations of Newco and its subsidiaries taken as a
          whole or on the ability of Newco to consummate the transactions
          contemplated hereby, or any event or condition which would, with the
          passage of time, have such effect; and

                    (ii) will not result in (a) a breach of, constitute a
          default under, accelerate any obligation under, or give rise to a
          right of termination of, any indenture or loan or credit agreement or
          any other agreement, contract, instrument, mortgage, lien, lease,
          permit, authorization, order, writ, judgment, injunction, decree,
          determination or








                                       12
<PAGE>   16

          arbitration award to which Newco is a party or by which the property
          of Newco is bound or affected, or (b) the creation or imposition of
          any mortgage, pledge, lien, security interest or other charge or
          encumbrance on any of the assets or on the capital stock of Newco
          except, in the case of clause (a) for such breaches, defaults,
          accelerations or terminations as would not, individually or in the
          aggregate, have a material adverse effect or result in a change in the
          condition (financial or other), business, results of operations,
          prospects, assets, Liabilities or operations of Newco and its
          subsidiaries taken as a whole or on the ability of Newco to consummate
          the transactions contemplated hereby, or any event or condition which
          would, with the passage of time, have such effect.

          3.5. Investor Representations. Newco will be acquiring the Shares for
its own account for investment only, and not with the view to, or for resale in
connection with, any distribution thereof. It will understand that the Shares to
be acquired will not be registered under the Securities Act by reason of a
specific exemption from the registration provisions of the Securities Act, the
availability of which depends upon, among other things, the bona fide nature of
Newco's investment intent.

          3.6. Formation of Newco. Newco will be formed for the sole purpose of
engaging in the Incorporation Transaction, will have conducted no other business
since its formation and will have no Liabilities upon the Closing except as
provided herein and for expenses related to its formation.

                                   ARTICLE IV.

                                   COVENANTS.

          4.1. Further Assurances. Upon the terms and subject to the conditions
contained herein, each Shareholder, Nextera and KE, agree, both before and after
the Closing, (a) to use all reasonable efforts to take, or cause to be taken,
all actions and to do, or cause to be done, all things necessary, proper or
advisable to consummate and make effective the transactions to be effected by it
pursuant to this Agreement, (b) to execute any documents, instruments or
conveyances of any kind which may be reasonably necessary or advisable to be
executed by it to carry out any of the transactions contemplated hereunder, and
(c) to cooperate with each other in connection with the foregoing. Without
limiting the foregoing, each Shareholder and Nextera agree to use their
respective commercially reasonable efforts (i) to obtain all necessary waivers,
consents and approvals from other parties to effectuate the exchange of shares
by such person described in Article I hereto; provided, however, that no party
shall be required to make any payments, commence litigation or agree to any
other modifications of the terms thereof in order to obtain any such waivers,
consents or approvals, (ii) to give all notices to, and make all registrations
and filings with third parties, including without limitation submissions of
information requested by governmental authorities, and (iii) to fulfill all
conditions to this Agreement.

          4.2. Incorporation Transaction. KE agrees to effect the Incorporation
Transaction pursuant to Section 11 of the First Amendment on or before January
1, 1999,






                                       13
<PAGE>   17

provided that in the event Nextera extends the Closing pursuant to Section 1.2,
KE agrees to effect the Incorporation Transaction by such extended date.

          4.3. No Distribution of Nextera Class A Units to the U.S.
Shareholders. The U.S. Shareholders shall cause General Partner and Limited
Partner to retain the Nextera Class A Units issued to the Partnership other than
such Nextera Class A Units deposited pursuant to the U.S. Escrow Agreement, and,
except as provided below, to not distribute such Nextera Class A Units to the
U.S. Shareholders, provided that the Partnership shall distribute the Nextera
Class A Units to General Partner and Limited Partner other than such Nextera
Class A Units deposited pursuant to the U.S. Escrow Agreement. General Partner
and Limited Partner may distribute the Nextera Class A Units to the U.S.
Shareholders or their Permitted Assignees if Nextera or KE has breached their
respective obligations to effect the Incorporation Transaction on the schedule
set forth in Section 1.2.

          4.4. Conversion of the Partnership. Prior to the Closing, the U.S.
Shareholders, General Partner and Limited Partner shall cause the Partnership to
be converted to a limited liability company, none of the membership interests of
which will be owned by General Partner or Limited Partner.

          4.5. No Solicitation of Other Offers; No Sale of Shares. No U.S.
Shareholder will, directly or indirectly, solicit, encourage, assist, initiate
discussions or engage in negotiations with, provide any information concerning
the operations, properties or assets of the Partnership, General Partner or
Limited Partner, or entertain or enter into any agreement or transaction with,
any person, other than SC/NE, LLC or Nextera, relating to the possible
acquisition of the equity of the Partnership, General Partner or Limited Partner
or any of their assets. If such a proposal is received, such U.S. Shareholder
will promptly notify Nextera of the terms of such proposal and the identity of
the party making the proposal. No U.S. Shareholder shall sell, transfer or
assign his Shares without the prior written consent of Nextera; provided,
however, that any U.S. Shareholder may assign his right to receive the Newco
Class A Stock to a Permitted Assignee, provided (a) the Permitted Assignee
agrees in writing to be bound by the terms and provisions of this Agreement and
the Stockholders Agreement and (b) the U.S. Shareholder or Permitted Assignee
furnishes an opinion of counsel reasonably acceptable to Newco such that the
transfer does not violate federal or state securities laws. If the U.S.
Shareholder represents to Newco in writing that the transfer was made as a bona
fide gift without payment of consideration, no securities law opinion is
required. For purposes of this agreement, the term "Permitted Assignee" shall
mean (i) any transferee by will or pursuant to the laws of descent and
distribution to any member or members of a U.S. Shareholder's Family (as defined
below) or (ii) a domestic trust created for the sole benefit of a U.S.
Shareholder or such U.S. Shareholder's Family, provided that in any case where
the U.S. Shareholder is not the trustee with the exclusive right and power
during his life to cast the votes attributable to the Shares and Newco Class A
Stock, as applicable, the trustee of each such trust shall grant an irrevocable
proxy to the Shareholder Representative (or another individual or entity
reasonably acceptable to Nextera) to vote the Newco Class A Stock held by it on
all matters at all times prior to the initial public offering of Newco Class A
Stock. For purposes of this Agreement, the term "Family" shall mean a person's
spouse, lineal






                                       14
<PAGE>   18

descendants, parents, siblings, and lineal descendants of siblings (including
any such relationship by legal adoption).

          4.6. Notification of Certain Matters. From the date hereof through the
Closing, the Shareholders and Nextera, shall give prompt notice to the other of
(a) the occurrence, or failure to occur, of any event which occurrence or
failure would be likely to cause any representation or warranty contained in
this Agreement or in any exhibit or schedule hereto to be untrue or inaccurate
in any respect and (b) any failure of such party, or any of its respective
affiliates or representatives, to comply with or satisfy any covenant, condition
or agreement to be complied with or satisfied by it under this Agreement or any
exhibit or schedule hereto; provided, however, that such disclosure shall not be
deemed to cure any breach of a representation, warranty, covenant or agreement
or to satisfy any condition.

          4.7. Boards of Directors and Officers. At the Closing, the directors
of General Partner and Limited Partner shall all resign. At the Closing, all the
officers of General Partner and Limited Partner shall likewise resign.

          4.8. Obligations of Newco. Nextera and KE agree to cause Newco to
perform all actions required to be performed by Newco under this Agreement.

          4.9. Tax Matters.

          (a) The U.S. Shareholders shall be responsible for all Liabilities for
Taxes with respect to all taxable periods of the Partnership ending on or prior
to the Closing Date and, to the extent provided in Section 4.9(b) hereof, all
taxable periods that include, and end after, the Closing Date other than, in
each case, Taxes which have been taken into account in the Working Capital
Adjustment (as defined in Section 2.5 of the Purchase Agreement).

          (b) For federal income tax purposes, the U.S. Shareholders and Nextera
agree that the taxable period for which General Partner and Limited Partner are
"S" corporations will end as of the close of business on the day immediately
preceding the Closing Date and that the taxable periods for which General
Partner and Limited Partner are "C" corporations will begin as of the beginning
of business on the Closing Date. For all other Tax purposes, the U.S.
Shareholders will cause General Partner and Limited Partner, to the extent
permitted by applicable law, to close the taxable periods of General Partner and
Limited Partner on the day immediately preceding the Closing Date, and on the
Closing Date, respectively. In any case where applicable law does not permit
General Partner and Limited Partner to close its taxable period on the day
immediately preceding the Closing Date, or on the Closing Date, as the case may
be, then Taxes, if any, attributable to the taxable periods of General Partner
and Limited Partner beginning on or before and ending after the Closing Date
shall be allocated (A) to the U.S. Shareholders for the period up to and
including the Closing Date and (B) to Newco for the period subsequent to the
Closing Date. For purposes of this Section 4.9(b), Taxes for the period up to
and including the Closing Date and for the period subsequent to the Closing Date
shall be determined on the basis of an interim closing of the books as of the
Closing Date or, to the extent not susceptible to such allocation, by
apportionment on the basis of elapsed days.




                                       15
<PAGE>   19

          (c) Newco shall be responsible for all Liabilities for Taxes of
General Partner and Limited Partner with respect to all taxable periods of
General Partner and Limited Partner beginning on and after the Closing Date and,
to the extent provided in Section 4.9(b) hereof, all taxable periods that
include, and end after, the Closing Date.

          (d) (i) The U.S. Shareholders shall prepare or cause to be prepared,
and shall file or cause to be filed, all Tax Returns required to be filed by or
on behalf of General Partner and Limited Partner which relate to taxable periods
(or portions thereof) ending on or prior to the Closing Date ("Pre-Closing Date
Tax Returns") and shall cause to be paid any Taxes shown to be due thereon
(other than Taxes which have been taken into account in the Working Capital
Adjustment) except as otherwise provided herein. Newco shall be responsible for
preparing and filing or causing to be prepared and filed all Tax Returns
required to be filed by or on behalf of General Partner and Limited Partner and
any of their operations and/or assets on and after the Closing Date and shall
pay or cause to be paid any Taxes shown to be due thereon.

               (ii) With respect to any Tax Return required to be filed by Newco
for a taxable period of General Partner or Limited Partner beginning before and
ending after the Closing Date, Newco shall provide the Shareholder
Representative with copies of such Tax Return, along with a calculation setting
forth the amount of Tax shown on such Tax Return for which Newco believes the
U.S. Shareholders are responsible, at least thirty (30) Business Days prior to
the due date for filing of such Tax Return. The Shareholder Representative shall
have the right to review such Tax Return and calculation prior to the filing of
such Tax Return. The Shareholder Representative and Newco agree to consult and
resolve in good faith any issues arising as a result of the review of such Tax
Return and calculation and to mutually consent to the filing of such Tax Return
as promptly as possible. In the event the parties are unable to resolve any
dispute, the parties shall jointly request an independent accounting firm to
resolve any issue in dispute as promptly as possible. The fees and expenses of
such accounting firm to resolve any issue in dispute as promptly as possible.
The fees and expenses of such accounting firm shall be paid one-half by the U.S.
Shareholders and one-half by Newco. Not later than the later of (i) five (5)
days before the due date for payment of Taxes with respect to such Tax Return or
(ii) in the event of a dispute, five (5) days after written notice to the U.S.
Shareholders of the resolution thereof, the U.S. Shareholders shall pay to Newco
an amount equal to the Taxes allocable to the U.S. Shareholders.

          (e) Newco shall promptly notify the U.S. Shareholders in writing upon
receipt by Newco, General Partner, Limited Partner or their affiliates of notice
of any pending or threatened Tax audits of or assessments against General
Partner or Limited Partner for any taxable period ending on, prior to or
including the Closing Date. Other than any claim, audit or other proceeding
concerning the validity or the status of the "S" corporation elections of
General Partner or Limited Partner, the Shareholder Representative shall have
the right to represent General Partner's and Limited Partner's interests in any
Tax audit or administrative or court proceeding with respect to any taxable
period ending on, prior to or including the Closing Date, to employ counsel of
their choice at their expense and to agree to a settlement or compromise of any
such audit or proceeding. The parties agree that they will cooperate fully with
each other and






                                       16
<PAGE>   20

their respective counsel in the defense against or compromise of any claim in
any audit or proceeding contemplated herein.

          (f) The parties hereto agree to furnish or cause to be furnished to
each other, at their own expense, such information, access to-books and records,
and assistance, including making employees available during regular business
hours on a mutually convenient basis, as may reasonably be necessary for the
preparation and filing of any Tax Return contemplated by this Section 4.9.

          (g) Newco agrees to assign and promptly remit (and to cause General
Partner and Limited Partner to assign and promptly remit) to the U.S.
Shareholders all refunds (including interest thereon) of any Taxes received by
Newco, General Partner, Limited Partner or their affiliates for taxable periods
ending on, prior to or including the Closing Date. Newco agrees that, upon the
request of the U.S. Shareholders, Newco shall file, or cause General Partner and
Limited Partner to file, a claim for refund of any such Tax.

          (h) The U.S. Shareholders and the Buyer agree to treat any indemnity
payment made pursuant to this Agreement as an adjustment to the consideration
for the Shares for all federal, state, local and foreign income Tax purposes.

          (i) Notwithstanding anything to the contrary in this Agreement, the
representations, warranties and obligations of the parties set forth in this
Section 4.9 shall survive until the expiration of the applicable statute of
limitations.

                                   ARTICLE V.

          The obligations of the parties to consummate the transactions provided
for hereby are subject, in the discretion of such party, to the satisfaction, on

In addition, the performance of the obligations of the U.S. Shareholders is
subject, at the election of the U.S. Shareholders, to the condition that the
transactions described in the second paragraph of Section 1.1(a) occur
contemporaneously with the Closing.

               (d) any other breach (whether or not deliberate or willful) of

claim, action or proceeding asserted or instituted growing out of any matter or
thing constituting a breach of such representations, warranties or covenants.

for indemnification hereunder by giving written notice thereof to the
indemnifying party promptly on discovery and in any event within the period in
which indemnification claims can be made hereunder. If indemnification is sought
for a claim or Liability asserted by a third party, the indemnified party shall
also give written notice thereof to the indemnifying party promptly after it
receives notice of the claim or Liability being asserted, but the failure to do
so shall not relieve the indemnifying party from any Liability except to the
extent that it is prejudiced by the failure or delay in giving such notice. Such
notice shall summarize the basis for the claim for indemnification and any claim
or Liability being asserted by a third party. Within 20 days after receiving
such notice the indemnifying party shall give written notice to the indemnified
party stating whether it disputes the claim for indemnification and whether it
will defend against any third party claim or Liability at its own cost and
expense. If the indemnifying party fails to give notice that it disputes an
indemnification claim within 20 days after receipt of notice thereof, it shall
be deemed to have accepted and agreed to the claim, which shall become
immediately due and payable. The indemnifying party shall be entitled to direct
the defense against a third party claim or Liability with counsel selected by it
(subject to the consent of the indemnified party, which consent shall not be
unreasonably withheld) as long as the indemnifying party is conducting a good
faith and diligent defense and to compromise or settle it, with the consent of
the indemnified party which consent shall not be unreasonably withheld. The
indemnified party shall at all times have the right to fully participate at its
own expense in the defense of a third party






                                       21

claim or Liability, directly or through counsel; provided, however, that if the
named parties to the action or proceeding include both the indemnifying party
and the indemnified party and the indemnified party is advised that
representation of both parties by the same counsel would be inappropriate under
applicable standards of professional conduct, the indemnified party may engage
separate counsel at the expense of the indemnifying party. If no such notice of
intent to dispute and defend a third party claim or Liability is given by the
indemnifying party, or if such good faith and diligent defense is not being or
ceases to be conducted by the indemnifying party, the indemnified party shall
have the right, at the expense of the indemnifying party, to undertake the
defense of such claim or Liability (with counsel selected by the indemnified
party), and to compromise or settle it, with consent of the indemnifying party,
which consent shall not be unreasonably withheld. If the third party claim or
Liability is one that by its nature cannot be defended solely by the
indemnifying party, then the indemnified party shall make available such
information and assistance as the indemnifying party may reasonably request and
shall cooperate with the indemnifying party in such defense, at the expense of
the indemnifying party.

                                  ARTICLE VII.

                                  TERMINATION.

          7.1 Termination. At any time prior to the Closing, this Agreement may
be terminated by mutual written consent of all of the parties to this Agreement,
provided that the Shareholder Representative may consent on behalf of the
Shareholders. All obligations of the parties hereunder shall cease upon any
termination pursuant to Section 7.1, provided, however, that the provisions of
Article VII, Section 8.3 and Section 8.11 hereof shall survive any termination
of this Agreement. No termination shall relieve any party of any liability for
breach of this Agreement prior to such termination.

                                  ARTICLE VIII.

                                 MISCELLANEOUS.

          8.1. Canadian Shareholders. Notwithstanding anything to the contrary
contained herein, in the event that "Closing" under the Canadian Purchase
Agreement has not occurred prior to the Closing hereunder, the obligations
and/or representations of the Canadian Shareholders and the other parties hereto
with respect to Sections 1.5, 6.3 and 6.4 and the representations and warranties
of the Canadian Shareholders in Article II shall be deemed null and void and the
Canadian Shareholders shall be deemed to not be parties to this Agreement. The
terms and provisions of this Agreement shall otherwise survive.

          8.2. Survival of Representations, Etc. Each of the representations,
warranties, agreements, covenants and obligations herein are material, shall be
deemed to have been relied upon by the other party and shall survive the Closing
regardless of any investigation and shall not merge in the performance of any
obligation by either party hereto.

          8.3. Fees and Expenses. Except as otherwise specified in this
Agreement, each party hereto shall pay its own legal, accounting, out-of-pocket
and other expenses incident to this Agreement and to any action taken by such
party in preparation for carrying this Agreement into effect. In the event that
Nextera extends the Closing beyond January 1, 1999 pursuant to Section 1.2,
Nextera shall reimburse the U.S. Shareholders for all costs and expenses
reasonably incurred by them and General Partner and Limited Partner as a result
of such extension up to a maximum aggregate reimbursement of $100,000 per annum.
Notwithstanding the foregoing, in the event Nextera, Newco or KE breaches any
material provision of this Agreement, including, without limitation, the
obligation to effect the Incorporation Transaction on the schedule set forth in
Section 1.2, and the U.S. Shareholders bring an action as a result of such
breach which is successful in whole or in any substantive part, the U.S.
Shareholders shall be entitled to receive from Nextera reimbursement for
reasonable attorneys fees in connection with the enforcement of this Agreement.

          8.4. Governing Law. This Agreement shall be construed under and
governed by the internal laws of the State of New York without regard to its
conflict of laws provisions.

          8.5. Notices. Any notice, request, demand or other communication
required or permitted hereunder shall be in writing and shall be deemed to have
been given if delivered or sent by facsimile transmission, upon receipt, or if
sent by registered or certified mail, upon the sooner of the date on which
receipt is acknowledged or the expiration of three days after deposit in United
States post office facilities properly addressed with postage prepaid. All

          8.6. Entire Agreement. This Agreement and schedules and exhibits
hereto constitute the entire agreement of the parties with respect to its
subject matter, and supersede all previous written or oral negotiations,
commitments and writings. No promises, representations, understandings,
warranties and agreements have been made by any of the parties hereto except as
referred to herein or in such schedules and exhibits; and all inducements to the
making of this Agreement relied upon by either party hereto have been expressed
herein or in such schedules or exhibits.

          8.7. Assignability; Binding Effect. This Agreement shall only be
assignable by (a) Nextera or KE to an entity controlling, controlled by or under
common control with Nextera or KE upon written notice to Shareholder
Representative or (b) a U.S. Shareholder to a Permitted Assignee; provided,
however, that Nextera, KE or such U.S. Shareholder, as applicable, shall remain
liable for all obligations hereunder to the extent such obligations are not
satisfied by the transferee. Except as provided in the preceding sentence, this
Agreement may not be assigned by the Shareholders without the prior written
consent of Nextera. This Agreement shall be binding upon and enforceable by, and
shall inure to the benefit of, the parties hereto and their respective
successors and permitted assigns. Assignment of this Agreement by any party
shall not relieve such party from its obligations hereunder.

          8.8. Captions and Gender. The captions in this Agreement are for
convenience only and shall not affect the construction or interpretation of any
term or provision hereof. The use in this Agreement of the masculine pronoun in
reference to a party hereto shall be deemed to include the feminine or neuter,
as the context may require.

          8.9. Execution in Counterparts. For the convenience of the parties and
to facilitate execution, this Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which shall
constitute one and the same document.

          8.10. Amendments. This Agreement may not be amended or modified, nor
may compliance with any condition or covenant set forth herein be waived, except
by a writing duly and validly executed by each party hereto, or in the case of a
waiver, the party waiving compliance, provided, however, that no amendment or
modification of this agreement or waiver of compliance with any condition or
covenant that has been duly and validly executed in writing by the Shareholder
Representative shall require the consent of, or execution thereof by, any
Shareholder and shall be valid and binding without such consent or execution.

          8.11. Specific Performance. The parties agree that it would be
difficult to measure damages which might result from a breach of this Agreement
by any party and that money damages would be an inadequate remedy for such a
breach. Accordingly, if there is a breach or proposed breach of any provision of
this Agreement by any Shareholder, on the one hand, or by Nextera or KE, on the
other, Nextera or the Shareholders, as applicable, shall be entitled, in
addition to any other remedies which it may have, to an injunction or other
appropriate equitable relief to restrain such breach without having to show or
prove actual damage to Nextera, the Shareholders, as applicable.

          8.12. Termination of Shareholders Agreements. Each GP Shareholder by
signing below hereby agrees to terminate that certain Shareholders Agreement
dated as of October 31, 1993, as amended, among General Partner and the
shareholders identified therein, effective upon the Closing. Each LP Shareholder
by signing below hereby agrees to terminate that certain Shareholders Agreement
dated as of January 1, 1998, as amended, among Limited Partner and the
shareholders identified therein, effective upon the Closing.

               (c) Mandatory Prepayments. The Company shall, within five days of
receipt by any Credit Party of the Net Cash Proceeds of any Asset Sale, Debt
Incurrence or Equity Issuance, prepay a principal amount of the Notes equal to
the amount of such Net Cash Proceeds (less any amounts not required to be paid
as a result of the requirement in subsection (d) of this Section 2.7 that all
such prepayments be made in multiples of $1,000), at a redemption price equal
to one hundred percent (100.00%) of the principal amount of the Notes so prepaid
together with accrued interest to the date of prepayment; provided, that the
redemption price shall be one hundred three percent (103.00%) of par plus
accrued interest if the Notes are

redeemed with or in anticipation of funds raised by any means other than (i) an
initial public offering at a minimum of at least, if not greater than, $75
million of the Company's common stock lead managed by DLJSC, (ii) a private
placement at a minimum of at least, if not greater than, $75 million of the
Company's common stock or other equity securities in which DLJSC is the lead
placement agent, (iii) a bank deal in which DLJSC is the loan originator and

Company to Purchaser.

               (d) Minimum Amount. Any prepayment of the Notes pursuant to
Section 2.7(b) shall be in a minimum amount of at least $1,000,000, unless less
than $1,000,000 of the Notes remain outstanding, in which case all of the Notes
must be prepaid. Any prepayment of the Notes pursuant to Section 2.7(c) shall be
in a minimum amount which is a multiple of $1,000 times the number of Holders at
the time of such prepayment.

               (e) Partial Prepayments. Any partial prepayment shall be made so
that the Notes then held by each Holder shall be prepaid in a principal amount
which shall bear the same ratio, as nearly as may be, to the total principal
amount being prepaid as the principal amount of such Notes held by such Holder
shall bear to the aggregate principal amount of all Notes then outstanding. In
the event of a partial prepayment, upon presentation of any Note the Company
shall execute and deliver to or on the order of the Holder, at the expense of
the Company, a new Note in principal amount equal to the remaining outstanding
portion of such Note.

Purchaser or any other Holder under any Financing Document shall be made without
deduction for any Taxes or Other Taxes; provided that, if any Credit Party shall
be required by law to deduct any Taxes or Other Taxes from any such payment, the
sum payable shall be increased as necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section), Purchaser or such Holder (as the case may be) receives an amount
equal to the sum it would have received had no such deductions been made, the
Credit Party shall make such deductions, the Credit Party shall pay the full
amount deducted to the relevant taxation authority or other authority in
accordance with applicable law and the Company shall promptly furnish to the
Purchaser or such Holder (as the case may be) the original or a certified copy

any liability (including penalties, interest and expenses) arising therefrom or
with respect thereto.

            (d) The Company shall have no obligations for Taxes under Section
2.8(a) or Section 2.8(b) for or on account of:

                    (i) any Taxes (other than Other Taxes) imposed by way of
deduction or withholding that would not have been so imposed but for the
existence of any present or former connection between such Holder and the
jurisdiction imposing the Tax other than merely holding such Note or any
Financing Document, or the receipt of payments in respect thereof, including,
without limitation, such Holder being or having been a citizen or resident
thereof, or being or having been engaged in a trade or business or having a
permanent establishment or other fixed base therein, or making or having made an
election to the effect of which is to subject such Holder to such Tax;

request by the Company addressed to such Holder or beneficial owner to provide
(A) information concerning the nationality, residence or identity of such Holder
or beneficial owner that is required under a statute, treaty, regulation or

Taxes of Purchaser or such other Holder (calculated based on a hypothetical
basis at the maximum marginal rate for a corporation) and any liability
(including penalties, interest and expenses) arising therefrom or with respect
thereto, in each case to the extent that such Domestic Taxes result from any

shall be paid within 15 days after Purchaser or such Holder (as the case may be)
makes demand therefor.

               (f) The Company agrees that the provisions of this Section shall

                                   ARTICLE III
                         REPRESENTATIONS AND WARRANTIES


               The Company represents and warrants to Purchaser (both before and
after giving effect to each Acquisition) as set forth below:

               Section 3.1. Corporate Existence and Power. Each Credit Party is
a corporation, limited liability company or limited partnership, as applicable,
duly incorporated or formed, as applicable, validly existing and in good
standing under the laws of the state of its incorporation, and has all
corporate, limited liability company or limited partnership powers, as
applicable, and all governmental licenses, authorizations, consents and
approvals required to carry on its business as now conducted and as proposed to
be conducted after each Acquisition except for such governmental licenses,
authorizations, consents and approvals as to which the failure to so maintain
could not reasonably be expected to have a Material Adverse Effect.

               Section 3.2. Authorization, Execution and Enforceability. The
execution, delivery and performance by each Credit Party party to each of the
Financing Documents and the Material Acquisition Documents and the issuance of
the Notes by the Company have been duly and validly authorized and are within
each such Credit Party's corporate, limited liability company or limited
partnership powers, as applicable. Each of the Financing Documents (other than
the Notes) and Material Acquisition Documents has been duly executed and
delivered by the Credit Parties party thereto and constitutes their valid and
binding agreement, enforceable in accordance with its terms, subject to
applicable bankruptcy, insolvency and other similar laws affecting creditors'
rights generally and equitable principles of general applicabil-


                                       21

<PAGE>   23


ity. When executed and delivered by the Company against payment therefor in
accordance with the terms hereof, the Notes will constitute valid and binding
obligations of the Company, enforceable in accordance with their terms, subject
to applicable bankruptcy, insolvency and other similar laws affecting creditors'
rights generally and equitable principles of general applicability.

               Section 3.3. Governmental Authorization; Compliance with Laws.
The execution and delivery by the Credit Parties party to each of the Financing
Documents and Material Acquisition Documents did not and will not, the issuance
and sale of the Notes by the Company will not, and the consummation of the
transactions contemplated hereby and thereby will not, require any action by or
in respect of, or filing with, any governmental body, agency or governmental
official except actions and filings which, if not taken or made, will not affect
in any manner the validity or enforceability of the Financing Documents or the
Material Acquisition Documents or could reasonably be expected to have a
Material Adverse Effect. Each Credit Party is in compliance with all applicable
laws, ordinances, rules, regulations and requirements of governmental
authorities except to the extent such compliance is not material to the
business, assets, property, condition (financial or otherwise) of such Credit
Party.

               Section 3.4. Non-Contravention. The execution and delivery by the
Credit Parties party to each of the Financing Documents and the Material
Acquisition Documents did not and will not, and the issuance and sale of the
Notes by the Company will not, and the consummation of the transactions
contemplated hereby and thereby will not, contravene or constitute a default
under or violation of any provision of applicable law or regulation, any Company
Corporate Documents or any agreement, judgment, injunction, order, decree or
other instrument binding upon any Credit Party or any of its assets, or result
in the creation or imposition of any Lien on any asset of any Credit Party
(other than the Liens created by the Security Documents).

               Section 3.5. Financial Information.

               (a) The (i) consolidated financial statements of each Credit
Party including balance sheets and incomes and cash flow statements as of the
end of and for each of the last three fiscal years audited by independent public
accountants of recognized national standing and prepared in conformity with
GAAP, together with the report thereon; (ii) unaudited selected financial
information of each Credit Party meeting the requirements of Item 301(a) of
Regulation S-K for the two fiscal years immediately preceding the last three

statements of each Credit Party, prepared in each case in the same manner as the
historical audited statements for the most recently ended quarterly period and
for the same quarterly period during the most recently ended fiscal year, fairly
present, in conformity with GAAP, the consolidated financial position of such
entities as of each such date and their consolidated results of operations,
changes in stockholders' equity and cash flows for each period (subject to
footnote presentation and normal year-end adjustments).

            (b) The unaudited pro forma consolidated balance sheet of the
Company as of June 30, 1998 (including the notes thereto) (the "Pro Forma
Balance Sheet"), copies of which have heretofore been furnished to the
Purchaser, has been prepared giving effect (as if such events had occurred on
such date) to (i) the consummation of each Acquisition, (ii) Debt to be issued
on or about the date of Closing and the use of proceeds thereof and (iii) the
payment of fees and expenses in connection with the foregoing. The Pro Forma
Balance Sheet has been prepared based on the best information available to the

basis the estimated financial position of the Company as of June 30, 1998,
assuming that the events specified in the preceding sentence had actually

with respect thereto.

is no action, suit or proceeding pending or, to the knowledge of any Credit

each case taken together and on the date as of which such information is

the rights of the holder of any such Permit; and (d) each Credit Party has no
reason to believe that any governmental body or agency is considering limiting,
suspending or revoking any such Permit.

            Section 3.16. Representations in Other Financing Documents and in

Notes (in the case of the Company) and perform its obligations under any
Financing Document.

other terms as are, in the reasonable opinion of DLJSC, prevailing for new
issues of securities of comparable size and credit rating in the capital
markets at the time such Permanent Financing is consummated and obtained in
comparable transactions made on an arm's length basis between unaffiliated
parties. The amount to be financed shall be in an amount at least sufficient to
repay or redeem the Notes in full in accordance with their terms. The Company
hereby covenants and agrees that the proceeds from the Permanent Financing shall
be used to the extent required to redeem in full the Notes in accordance with
their terms.

            (b) The Company covenants that it will, and will cause each Credit
Party to, enter into such agreements as in the judgment of DLJSC are customary
in connection with the Permanent Financing, make such filings under the
Securities Act, the Exchange Act, the Trust Indenture Act of 1939, as amended,
and state securities laws as in the reasonable judgment of DLJSC shall be
required to permit consummation of the Permanent Financing and take such steps
as in the reasonable judgment of DLJSC are necessary or desirable to cause such
filings to become effective or in the judgment of DLJSC are otherwise required
to consummate the Permanent Financing.

            Section 6.17. Business Activities. The Company will not, and it will
not permit any Credit Party to, enter into any business, either directly or
through any Subsidiary or joint venture, except for those businesses of the same
type as or related to those in which the Credit Parties are engaged on the date
of this Agreement.

            Section 6.18. Maintenance of Separateness. The Company will, and
will cause each of its Subsidiaries to, satisfy customary corporate and limited
liability company formalities, as applicable, including the holding of regular
board of directors' and shareholders' meetings or action by directors or
shareholders without a meeting or similar meeting or actions for a limited
liability company and the maintenance of corporate or limited liability company
offices and records. Other than pursuant to any Subsidiary Guaranty entered into
pursuant to this Agreement, neither the Company nor any of its Subsidiaries
shall make any payment to a creditor of any other Subsidiary in respect of any
liability of any such Subsidiary. Any financial statements distributed to any
creditors of any Subsidiary shall clearly establish or indicate the separateness
of such Subsidiary from the Company and its other Subsidiaries. Neither the
Company nor any of its Subsidiaries shall take any action, or conduct its
affairs in a manner, which is likely to result in the corporate or limited
liability company existence of the Company or any of its Subsidiaries being
ignored, or in the assets and liabilities of the Company or any of its
Subsidiaries being substantively consolidated with those of any other such
Person in a bankruptcy, reorganization or other insolvency proceeding.

            Section 6.19. KU Debt. Neither the Company nor any Credit Party
shall amend or consent to any amendment of the KU Debt.

            Section 6.20. Sibson Canada. The Company will cause Sibson Canada to
deliver to Purchaser within five (5) Business Days from September 1, 1998 an
intercreditor agreement by and between the Toronto-Dominion Bank and Purchaser,
in a form reasonably satisfactory to Purchaser.

option of and by a holder of a Note; or

            (e) any Credit Party shall commence a voluntary case or other
proceeding seeking liquidation, reorganization or other relief with respect to
itself or its debts under any bankruptcy, insolvency or other similar law now or
hereafter in effect in any jurisdiction or seeking the appointment of a trustee,
receiver, liquidator, custodian or other similar official of it or any
substantial part of its property, or shall consent to any such relief or to the
appointment of or taking possession by any such official in an involuntary case
or other proceeding commenced against it, or shall make a general assignment for
the benefit of creditors, or shall fail generally to pay its debts as they
become due, or shall take any corporate action to authorize any of the
foregoing; or

<PAGE>   44

            (f) an involuntary case or other proceeding shall be commenced
against any Credit Party seeking liquidation, reorganization or other relief
with respect to it or its debts under any bankruptcy, insolvency or other
similar law now or hereafter in effect or seeking the appointment of a trustee,
receiver, liquidator, custodian or other similar official of it or any
substantial part of its property, and such involuntary case or other proceeding
shall remain undismissed and unstayed for a period of 60 days; or an order for
relief shall be entered against any Credit Party under the bankruptcy laws as
now or hereafter in effect in any jurisdiction; or

            (g) there shall be a default in respect of any Debt of any Credit
Party in an aggregate principal amount in excess of $500,000 whether such Debt
now exists or shall hereafter be created (excluding the Notes but including Debt
owing to any Credit Party) if such default results in acceleration of the
maturity of such Debt or enables the holder of such Debt to accelerate the
maturity thereof; or any Credit Party shall fail to pay at maturity any such
Debt whether such debt now exists or shall hereafter be created; or

            (h) final judgments for the payment of money which in the aggregate
at any one time exceed $500,000 shall be rendered against any Credit Party by a
court of competent jurisdiction and shall remain undischarged for a period
(during which execution shall not be effectively stayed) of 60 days after such
judgment becomes final; or

            (i) any representation, warranty, certification or statement made or
deemed made by any Credit Party in any Financing Document or which is contained
in any certificate, document or financial or other statement furnished at any
time under or in connection with any Financing Document shall prove to have been
untrue in any material respect when made or deemed made; or

            (j) any member of the ERISA Group has failed to pay when due an
amount or amounts aggregating in excess of $100,000 which it shall have become
liable to pay under Title IV of ERISA; or notice of intent to terminate a
Material Plan has been filed under Title IV of ERISA by any member of the ERISA
Group, any plan administrator or any combination of the foregoing; or the PBGC
has instituted proceedings under Title IV of ERISA to terminate, to impose
liability (other than for premiums under Section 4007 of ERISA) in respect of,
or to cause a trustee to be appointed to administer any Material Plan; or a
condition has existed by reason of which the PBGC is entitled to obtain a decree
adjudicating that any Material Plan must be terminated; or there has occurred a
complete or partial withdrawal from, or a default, within the meaning of Section
4219(c)(5) of ERISA, with respect to, one or




                                       43
<PAGE>   45

more Multiemployer Plans which could cause one or more members of the ERISA
Group to incur a current payment obligation in excess of $100,000; or

            (k) a breach under the Engagement Letter has occurred; or

            (l) any Subsidiary Guaranty shall have been disavowed thereunder, a
court of competent jurisdiction shall have determined that any Subsidiary
Guaranty is unenforceable or any guarantor thereunder shall default in the
performance of any of its obligations under any Subsidiary Guaranty; or

            (m) any of the Security Documents shall for any reason cease to be
in full force and effect, or shall cease to give Purchaser the Liens, rights,
powers and privileges purported to be created thereby including, without
limitation, a perfected first priority security interest in, and Lien on, all of
the collateral covered thereby in accordance with the terms thereof; or

            (n) a Change of Control has occurred;

then, and in each and every such case (other than under clauses (e) and (f) with
respect to any Credit Party), unless the principal of all the Notes shall have
already become due and payable, the Purchaser, by notice in writing to the
Company, may declare the entire principal amount of the Notes together with
accrued interest thereon to be immediately due and payable. If an Event of
Default specified in clauses (e) or (f) with respect to any Credit Party occurs,
the principal of and accrued interest on the Notes will be immediately due and
payable without any declaration or other act on the part of the Holders. If an
Event of Default shall occur and for as long as such Event of Default shall be
continuing, the Purchaser shall have the right to appoint one representative to
sit on the Board of Directors of the Company.

Notwithstanding the foregoing, in the event of any default hereunder or pursuant
to any of the Subsidiary Debt, the Company, at Purchaser's request, shall
promptly repay any or all of the Subsidiary Debt, including, at the Purchaser's
sole discretion, by means of the issuance of additional Notes by the Company on
the same terms and conditions as set forth in this Agreement.

                             LIMITATION ON TRANSFERS

            Section 8.1. Restrictions on Transfer. From and after the date of
each Takedown and their respective dates of issuance, as the case may be, none
of the Notes shall be transferable except upon the conditions specified in
Sections 8.2 and 8.3, which conditions are intended to ensure compliance with
the provisions of the Securities Act in respect of the Transfer of any of such
Notes or any interest therein. Purchaser will cause any proposed transferee of
any Notes (or any interest therein) held by it to agree to take and hold such
Notes (or any interest therein) subject to the provisions and upon the
conditions specified in this Section 8.1 and in Sections 8.2 and 8.3.

            Section 8.2. Restrictive Legends. (a) Each Note issued to Purchaser
or to a subsequent transferee shall (unless otherwise permitted by the
provisions of Section 8.2(b) or Section 8.3) include a legend in substantially
the following form:

      THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
      AMENDED, OR ANY STATE SECURITIES LAWS AND MAY NOT BE OFFERED OR SOLD,
      UNLESS IT HAS BEEN REGISTERED UNDER SUCH ACT AND APPLICABLE STATE
      SECURITIES LAWS OR UNLESS AN EXEMPTION FROM REGISTRATION IS AVAILABLE AND
      THEN ONLY IN COMPLIANCE WITH THE RESTRICTIONS ON TRANSFER SET FORTH IN THE
      SECURITIES PURCHASE AGREEMENT DATED AS OF AUGUST 31, 1998, A COPY OF WHICH
      MAY BE OBTAINED FROM THE ISSUER OF THIS SECURITY AT ITS PRINCIPAL
      EXECUTIVE OFFICE.

            (b) Any Holders of Notes registered pursuant to the Securities Act
and qualified under applicable state securities laws may exchange such Notes on
transfer for new securities that shall not bear the legend set forth in
paragraph (a) of this Section 8.2.

            Section 8.3. Notice of Proposed Transfers. (a) Five Business Days
prior to any proposed Transfer (other than Transfers of Notes (i) registered
under the Securities Act, (ii) to an Affiliate of DLJSC or a general partnership
in which DLJSC or an Affiliate of DLJSC is one of the general partners or (iii)
to be made in reliance on Rule 144A under the Securities Act) of any Notes, the
holder thereof shall give written notice to the Company of such holder's
intention to effect such Transfer, setting forth the manner and circumstances of
the proposed Transfer, and shall be


                                       45
<PAGE>   47


accompanied by (i) an opinion of counsel reasonably satisfactory to the Company
addressed to the Company to the effect that the proposed Transfer of such Notes
may be effected without registration under the Securities Act, (ii) such
representation letters in form and substance reasonably satisfactory to the
Company to ensure compliance with the provisions of the Securities Act and (iii)
such letters in form and substance reasonably satisfactory to the Company from
each such transferee stating such transferee's agreement to be bound by the
terms of this Agreement. Such proposed Transfer may be effected only if the
Company shall have received such notice of transfer, opinion of counsel,
representation letters and other letters referred to in the immediately
preceding sentence, whereupon the holder of such Notes shall be entitled to
Transfer such Notes in accordance with the terms of the notice delivered by the
holder. Each Note transferred as above provided shall bear the legend set forth
in Section 8.2(a) except that such Note shall not bear such legend if the
opinion of counsel referred to above is to the further effect that neither such
legend nor the restrictions on Transfer in Sections 8.1 through 8.3 are required
in order to ensure compliance with the provisions of the Securities Act.

              Five Business Days prior to any proposed Transfer of any Notes to
be made in reliance on Rule 144A under the Securities Act ("Rule 144A"), the
holder thereof shall give written notice to the Company of such holder's
intention to effect such Transfer, setting forth the manner and circumstances of
the proposed Transfer and certifying that such Transfer will be made (i) in full
compliance with Rule 144A and (ii) to a transferee that (A) such holder
reasonably believes to be a "qualified institutional buyer" within the meaning
of Rule 144A and (B) is aware that such Transfer will be made in reliance on
Rule 144A. Such proposed Transfer may be effected only if the Company shall have
received such notice of transfer, whereupon the holder of such Notes shall be
entitled to Transfer such Notes in accordance with the terms of the notice
delivered by the holder. Each Note transferred as above provided shall bear the
legend set forth in Section 8.2(a).


                                   ARTICLE IX
                                  MISCELLANEOUS

            Section 9.1. Notice. All notices, demands and other communications
to any party hereunder shall be in writing (including telecopier or similar
writing) and shall be given to such party at its address set forth on the
signature pages hereof, or such other address as such party may hereinafter
specify for the purpose. Each such notice, demand or other communication shall
be effective (i) if given by telecopy, when such telecopy is transmitted to the
telecopy number specified on the signature


                                       46
<PAGE>   48


page hereof, or (ii) if given by overnight courier, addressed as aforesaid or by
any other means, when delivered at the address specified in this Section.

            Section 9.2. No Waivers; Amendments. (a) No failure or delay on the
part of any party in exercising any right, power or remedy hereunder shall
operate as a waiver thereof, nor shall any single or partial exercise of any
such right, power or remedy preclude any other or further exercise thereof or
the exercise of any other right, power or remedy. The remedies provided for
herein are cumulative and are not exclusive of any remedies that may be
available to any party at law or in equity or otherwise.

            (b) Any provision of this Agreement may be amended, supplemented or
waived if, but only if, such agreement, supplement or waiver is in writing and
is signed by the Company and the Majority Holders; provided, that without the
consent of each Holder of any Note affected thereby, an amendment, supplement or
waiver may not (a) reduce the aggregate principal amount of Notes whose Holders
must consent to an amendment, supplement or waiver, (b) reduce the rate or
extend the time for payment of interest on any Note, (c) reduce the principal
amount of or extend the stated maturity of any Note or alter the redemption
provisions with respect thereto or (d) make any Note payable in money or
property other than as stated in the Notes. In determining whether the Holders
of the requisite principal amount of Notes have concurred in any direction,
consent, or waiver as provided in this Agreement or in the Notes, Notes which
are owned by the Company or any other obligor on or guarantor of the Notes, or,
by any Person controlling, controlled by, or under common control with any of
the foregoing, shall be disregarded and deemed not to be outstanding for the
purpose of any such determination; and provided further that no such amendment,
supplement or waiver which affects the rights of Purchaser and its Affiliates
otherwise than solely in their capacities as Holders of Notes shall be effective
with respect to them without their prior written consent.

            Section 9.3. Indemnification. The Company (the "Indemnifying Party")
agrees to indemnify and hold harmless Purchasers, its Affiliates, and each
Person, if any, who controls Purchaser, or any of its affiliates, within the
meaning of the Securities Act or the Exchange Act (a "Controlling Person"), and
the respective partners, agents, employees, officers and directors of Purchaser,
its Affiliates and any such Controlling Person (each an "Indemnified Party" and
collectively, the "Indemnified Parties"), from and against any and all losses,
claims, damages, liabilities and expenses (including, without limitation and as
incurred, reasonable costs of investigating, preparing or defending any such
claim or action, whether or not such Indemnified Party is a party thereto),
arising out of, or in connection with any activ-






                                       47
<PAGE>   49
ities contemplated by this Agreement or any of the services rendered in
connection herewith, including, but not limited to, losses, claims, damages,
liabilities or expenses arising out of or based upon any untrue statement or any
alleged untrue statement of a material fact or any omission or any alleged
omission to state a material fact in any of the disclosure or offering or
confidential information documents (the "Disclosure Documents") pertaining to
any of the transactions or proposed transactions contemplated herein, including
any eventual refinancing or resale of the Notes, provided that the Indemnifying
Party will not be responsible for any claims, liabilities, losses, damages or
expenses that are determined by final judgment of court of competent
jurisdiction to result from such Indemnified Party's gross negligence, willful
misconduct or bad faith. The Indemnifying Party also agrees that Purchaser shall
have no liability (except for breach of provisions of this Agreement) for
claims, liabilities, damages, losses or expenses, including legal fees, incurred
by the Indemnifying Party in connection with this Agreement unless they are
determined by final judgment of a court of competent jurisdiction to result from
(a) Purchaser's gross negligence, willful misconduct or bad faith, (b)
Purchaser's use of Disclosure Documents not approved by the Indemnifying Party
or (c) the failure of Purchaser to furnish to any purchaser of securities any
Disclosure Document furnished to Purchaser by the Indemnifying Party which
corrected any untrue statement of a material fact or omission to state a
material fact contained in a Disclosure Document previously furnished to such
purchaser by Purchaser.

            If any action shall be brought against an Indemnified Party with
respect to which indemnity may be sought against the Indemnifying Party under
this Agreement, such Indemnified Party shall promptly notify the Indemnifying
Party in writing and the Indemnifying Party shall, if requested by such
Indemnified Party or if the Indemnifying Party desires to do so, assume the
defense thereof, including the employment of counsel reasonably satisfactory to
such Indemnified Party and payment of all reasonable fees and expenses. The
failure to so notify the Indemnifying Party shall not affect any obligations the
Indemnifying Party may have to such Indemnified Party under this Agreement or
otherwise unless the Indemnifying Party is materially adversely affected by such
failure. Such Indemnified Party shall have the right to employ separate counsel
in such action and participate in the defense thereof, but the fees and expenses
of such counsel shall be at the expense of such Indemnified Party, unless: (i)
the Indemnifying Party has failed to assume the defense and employ counsel or
(ii) the named parties to any such action (including any impleaded parties)
include such Indemnified Party and the Indemnifying Party, and such Indemnified
Party shall have been advised by counsel that there may be one or more legal
defenses available to it which are different from or additional to those
available to the Indemnifying Party, in which case, if such Indemnified Party
notifies


                                       48
<PAGE>   50


the Indemnifying Party in writing that it elects to employ separate counsel at
the expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense of such action or proceeding on behalf of such
Indemnified Party, provided, however, that the Indemnifying Party shall not, in
connection with any one such action or proceeding or separate but substantially
similar or related actions or proceedings in the same jurisdiction arising out
of the same general allegations or circumstances, be responsible hereunder for
the reasonable fees and expenses of more than one such firm of separate counsel,
in addition to any local counsel, which counsel shall be designated by
Purchaser. The Indemnifying Party shall not be liable for any settlement of any
such action effected without the written consent of the Indemnifying Party
(which shall not be unreasonably withheld) and the Indemnifying Party agrees to
indemnify and hold harmless each Indemnified Party from and against any loss or
liability by reasons of settlement of any action effected with the consent of
the Indemnifying Party. In addition, the Indemnifying Party will not, without
the prior written consent of Purchaser, settle or compromise or consent to the
entry of any judgment in or otherwise seek to terminate any pending or
threatened action, claim, suit or proceeding in respect of which indemnification
or contribution may be sought hereunder (whether or not any Indemnified Party is
a party thereto) unless such settlement, compromise, consent, or termination
includes an express unconditional release of Purchaser and the other Indemnified
Parties, reasonably satisfactory in form and substance to Purchaser, from all
liability arising out of such action, claim, suit or proceeding.

            If for any reason the foregoing indemnity is unavailable (otherwise
than pursuant to the express terms of such indemnity) to an Indemnified Party or
insufficient to hold an Indemnified Party harmless, then in lieu of
indemnifying the Indemnified Party, the Indemnifying Party shall contribute to
the amount paid or payable by such Indemnified Party as a result of such claims,
liabilities, losses, damages, or expenses (i) in such proportion as is
appropriate to reflect the relative benefits received by the Indemnifying Party
on the one hand and by Purchaser on the other from the transactions contemplated
by this Agreement or (ii) if the allocation provided by clause (i) is not
permitted under applicable law, in such proportion as is appropriate to reflect
not only the relative benefits received by the Indemnifying Party on the one
hand and Purchaser on the other, but also the relative fault of the Indemnifying
Party and Purchaser as well as any other relevant equitable considerations.
Notwithstanding the provisions of this Section 9.3, the aggregate contribution
of all Indemnified Parties shall not exceed the amount of fees actually received
by Purchaser pursuant to this Agreement. It is hereby further agreed that the
relative benefits to the Indemnifying Party on the one hand and the Purchaser on
the other with respect to the transactions contemplated hereby shall be
determined by


                                       49
<PAGE>   51

reference to, among other things, whether any untrue or alleged untrue
statements of material fact or the omission or alleged omission to state a
material fact related to information supplied by the Indemnifying Party or by
Purchaser and the party's relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. No Person guilty
of fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any Person who was not
guilty of such fraudulent misrepresentation.

            The indemnification, contribution and expense reimbursement
obligations set forth in this Section 9.3 (i) shall be addition to any liability
the Indemnifying Party may have to any Indemnified Party at common law or
otherwise, (ii) shall survive the termination of this Agreement and the payment
in full of the Notes and (iii) shall remain operative and in full force and
effect regardless of any investigation made by or on behalf of Purchaser or any
other Indemnified Party.

            Section 9.4. Expenses. The Company agrees to pay all reasonable
out-of-pocket costs, expenses and other payments in connection with the purchase
and sale of the Notes as contemplated by this Agreement including without
limitation (i) fees and disbursements of special counsel and any local counsel
for Purchaser incurred in connection with the preparation of this Agreement,
(ii) all reasonable out-of-pocket expenses of Purchaser, including reasonable
fees and disbursements of counsel, in connection with any waiver or consent
hereunder or any amendment hereof or any Default or alleged Default hereunder
and (iii) if an Event of Default occurs, all reasonable out-of-pocket expenses
incurred by Purchaser and each holder of Notes, including reasonable fees and
disbursements of a single counsel (which counsel shall be selected by Purchaser
if Purchaser is a holder of Notes when such Event of Default occurs), in
connection with such Event of Default and collection, bankruptcy, insolvency and
other enforcement proceedings resulting therefrom.

            Section 9.5. Payment. The Company agrees that, so long as Purchaser
shall own any Notes purchased by it from the Company hereunder, the Company will
make payments to Purchaser of all amounts due thereon by wire transfer by 1:00
PM (New York City time) on the date of payment to such account as is specified
beneath Purchaser's name on the signature page hereof or to such other account
or in such other similar manner as Purchaser may designate to the Company in
writing.

            Section 9.6. Successors and Assigns. This Agreement shall be binding
upon and shall inure to the benefit of the Company and Purchaser and their
respective successors and assigns; provided that the Company may not assign or
otherwise


                                       50
<PAGE>   52


transfer its rights or obligations under this Agreement to any other Person
without the prior written consent of the Majority Holders except pursuant to the
Nextera Incorporation. All provisions hereunder purporting to give rights to
DLJSC and its Affiliates or to Holders are for the express benefit of such
Persons.

            Section 9.7. Brokers. The Company represents and warrants that,
except for DLJSC, neither it nor any Credit Party has employed any broker,
finder, financial advisor or investment banker who might be entitled to any
brokerage, finder's or other fee or commission in connection with any
Acquisition or the sale of the Notes.

            Section 9.8. New York Law; Submission to Jurisdiction; Waiver of
Jury Trial. THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY
THE LAWS OF THE STATE OF NEW YORK. EACH PARTY HERETO HEREBY SUBMITS TO THE
NONEXCLUSIVE JURISDICTION OF THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN
DISTRICT OF NEW YORK AND OF ANY NEW YORK STATE COURT SITTING IN NEW YORK CITY
FOR PURPOSES OF ALL LEGAL PROCEEDINGS ARISING OUT OF OR RELATING TO THIS
AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY HERETO IRREVOCABLY
WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW
OR HEREAFTER HAVE TO THE LAYING OF THE VENUE OF ANY SUCH PROCEEDING BROUGHT IN
SUCH A COURT AND ANY CLAIM THAT ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT HAS
BEEN BROUGHT IN AN INCONVENIENT FORUM. EACH PARTY HERETO HEREBY IRREVOCABLY
WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF
OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

            Section 9.9. Severability. If any term, provision, covenant or
restriction of the Agreement is held by a court of competent jurisdiction to be
invalid, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions of this Agreement shall remain in full force and
effect and shall in no way be affected, impaired or invalidated.

            Section 9.10. Counterparts. This Agreement may be executed in any

rights, whether vested or contingent, with regard to, any of Executive's
options or similar programs in which the Executive is then participating.

      15.   Approval of Publicity. Company and Executive shall mutually approve
all press releases and other items of publicity with respect to Executive's

                                      -12-
<PAGE>   13
            16.2  Covenant as to Nondisclosure or Use of Confidential
Information. Executive agrees that at all times during the Employment Term
hereunder and for a period of two (2) years thereafter, he will not, unless
required to do so pursuant to legal process such as subpoena, disclose to any
individual or business enterprise of any nature, or use for his own personal
use or financial gain, whether individually or on behalf of another person,
firm, corporation or entity, any Confidential Information which Executive has
obtained or will obtain in connection with his employment with Company. Such
restrictions shall not apply to information which has become public prior to
such disclosure by Executive. In the event Executive is required by legal
process to disclose any Confidential Information, he shall give prompt notice
thereof to Company to allow Company to object to such process, obtain a
protective order, or take any other action it deems necessary.

            16.3  Return of Business Records. Upon termination of Executive's
employment, Executive shall promptly, if so requested by Company, return all
documents, records, procedures, books, notebooks, and any other documentation
containing any information pertaining to the Company which includes
Confidential Information, including any and all copies of such documentation,
then in Executive's possession or control regardless of whether such
documentation was prepared or compiled by Executive, Company, other executives
of Company, representatives, agents, or independent contractors. Executive
acknowledges that all such 



                                      -13-
<PAGE>   14
documentation and copies of such documentation is and shall at all times remain
the sole and exclusive property of Company.

          16.4 Additional Covenants Protecting the Interests of Company.
Executive agrees that during his employment hereunder, and (a) for a period of
one year thereafter if the Employment Term ends for reasons other than either
cause, permanent disability, death or Executive terminating his employment
hereunder, or (b) for a period of five years from the date hereof, if the
Employment Term ends for any reason other than as stated in (a) above, Executive
shall not directly or indirectly, individually, or together through any other
person, firm, corporation or entity, without the prior written consent of
Company, engage in any business with any person or entity which is a customer or
client of Company, or approach, counsel, or attempt to induce any person who is
then in the employ of Company, to leave their employ, other than Executive's
secretary, or employ or attempt to employ any such person, other than
Executive's secretary, or aid or counsel any other person, firm, corporation, or
entity to do any of the above.

          16.5 Post-Employment Cooperation. Executive agrees that, for a period
of two (2) years following his termination of employment under this Agreement,
he shall, upon Company's reasonable request and in good faith and with his best
efforts, subject to his reasonable availability, cooperate and assist Company in
any dispute, controversy, or litigation in which Company may be involved and
with respect to which Executive obtained knowledge while employed by the Company
or any of its affiliates, successors, or assigns, including, but not limited to,
his








                                      -14-
<PAGE>   15
participation in any court or arbitration proceedings, giving of testimony,
signing of affidavits, or such other personal cooperation as counsel for Company
shall request. Any such activities shall be scheduled, to the extent reasonably
possible, to accommodate Executive's business and personal obligations at the
time. Company shall pay Executive's travel and incidental out-of-pocket expenses
incurred in connection with any such cooperation, as well as the costs of any
attorney Executive engages to advise him in connection with the foregoing.

          16.6 Remedies. In view of the position of confidence which Executive
will enjoy with Company and the anticipated relationship with the clients,
customers, and executives of Company pursuant to his employment hereunder, and
recognizing both the access to confidential financial and other information
which Executive will have pursuant to his employment, Executive expressly
acknowledges that the restrictive covenants set forth in this Section 16 are
reasonable and necessary in order to protect and maintain the proprietary
interests and other legitimate business interests of Company. Executive further
acknowledges that (a) it would be difficult to calculate damages to Company from
any breach of his obligations under this Section 16, (b) that injury to Company
from any such breach would be irreparable and impossible to measure, and (c)
that the remedy at law for any breach or threatened breach of this Section 16
would therefore be an inadequate remedy and, accordingly, Company shall, in
addition to all other available remedies, be entitled to injunctive and other
similar equitable remedies.

        17.     Dispute Resolution. If a dispute arises between the parties
concerning the interpretation of this Agreement or whether a party is in
violation of this Agreement, including but not limited to claims relating to
termination of this Agreement and definition of "cause", then either party may
deliver a written notice of such dispute to the other party (a "Dispute
Notice"). If such dispute is not resolved by the parties within ten (10) days
of the Dispute Notice, then the resolution of the dispute described in the
Dispute Notice shall be determined by an expedited arbitration proceeding
conducted under California law and the labor arbitration rules of the American
Arbitration Association (the "Arbitration") with discovery conducted pursuant
to the provisions of California Code of Civil Procedure Sections 2016 et seq.
Any arbitration proceeding determinations shall be binding on the parties. The
arbitration shall not be used to modify any provision of this Agreement and
shall merely interpret the provisions hereof.

        17.1    Selection and Conduct of Arbitrators. The Arbitration
proceeding shall be conducted by each of the parties appointing a qualified
arbitrator within twenty (20) days of the Dispute Notice. A qualified
arbitrator means a person who has had substantial experience in connection with
matters involving the interpretation of employment agreements and the
operations of companies similar to Company and who is unaffiliated with and
otherwise independent of the parties and their affiliates. The two arbitrators
so selected shall within the succeeding twenty (20) day period after their
selection attempt to reach agreement on the dispute submitted after considering
all of the evidence submitted


                                      -16-
<PAGE>   17
by the parties. If the arbitrators fail to reach an agreement within such
twenty (20) day period, they shall within five (5) days thereafter select a
third qualified arbitrator. In the event the two arbitrators are unable to
reach agreement on the third arbitrator, then the parties shall select a third
arbitrator from a list of seven arbitrators provided by the Los Angeles County
Office of the American Arbitration Association with each party having the right
to strike names in order until they either agree on an arbitrator from the
list, or until one arbitrator's name remains on the list. The party with the
right to strike the first name shall be determined by the flip of a coin. Such
third arbitrator shall determine the resolution of the dispute within the
succeeding twenty (20) day period and such decision shall be final and binding
on the parties.

        17.2    Sole and Exclusive Remedy. In consideration of the parties
agreement to submit all disputes hereunder to arbitration, and in further
consideration of minimizing the time and expense of resolving any dispute
pursuant hereto, the arbitration provisions shall be the sole and exclusive
remedy of the parties, and each party expressly waives the right to seek
resolution by any other means or in any other forum.

        17.3    Expiration of Claims. All claims that any other party has
against the other must be presented in writing within one (1) year of the date
the claiming party knew or should have known of the facts giving rise to the
claim, or, with respect to claims related to termination of Executive's
employment, within one (1) year of the date of termination hereunder. Any claim
not


                                      -17-
<PAGE>   18
brought within said time period shall be waived and forever barred unless the
party against whom such claim is made agrees to waive such time period.

        17.4    Enforceability and Costs. Upon completion of the arbitration,
either party may thereafter unilaterally and immediately cause the other to
comply with the decision made by the arbitration proceeding, and any such
decision may be entered in the Superior Court of the State of California or any
other court having jurisdiction. All arbitration costs during the arbitration
shall be paid equally by the parties until such time as a final decision is
made. Likewise, until such time as a final decision is made, each party shall
bear their own attorneys fees. The prevailing party shall receive a complete
reimbursement from the non-prevailing party upon completion of the arbitration
for all costs incurred by the prevailing party, including, but not limited to,
direct arbitration costs paid by the prevailing party and the prevailing
party's reasonable attorneys' fees and other costs.

        18.     Representations by Executive. Executive represents and warrants
that he is free to enter into and perform each of the terms and conditions of
this Agreement; and that his execution and/or performance of all his
obligations under this Agreement does not and will not violate or breach any
other agreement between Executive and any other person or entity.

        19.     Indemnification. Company shall, to the maximum extent permitted
by law, indemnify, defend, and hold Executive harmless for all claims, demands,
losses, costs, expenses, obligations, liabilities, damages, recoveries, and
deficiencies,


                                      -18-
<PAGE>   19
including reasonable attorneys' fees, that Executive shall incur or suffer that
arise from, result from, or relate to the discharge of Executive's duties under
this Agreement, except to the extent that Executive has acted in bad faith or
shall be guilty of willful misconduct, fraud, gross negligence, or a wrongful
taking.

          20.  General Provisions.

               20.1 Further Assurance. The parties agree that, at any time and
from time to time during the Employment Term, they will take any action and
execute and deliver any document which any other party reasonably requests in
order to carry out the purposes of this Agreement.

               20.2 Amendment of Agreement. This Agreement may be amended or
supplemented only in writing, and no amendment or supplement will be effective
unless executed by all of the parties.

communication required or permitted to be given by or to any person pursuant to
this Agreement (collectively "Notice") will be in writing, and will be given

bonus, except as provided in Section 7.2 above.

equity Executive purchases pursuant to this Section 7.4(b) at the original cost

years for any reason other than Executive's death, disability, cause (as

Company does not elect to extend the Employment Term past the initial three

(i) in a lump sum within thirty (30) days of the effective date of termination,
any base salary due through the date of termination; (ii) the balance of

entitled to continue appropriate benefits under any applicable Cobra program;
and (iv) the Company shall reimburse Executive for costs and expenses which he
has incurred and which would otherwise have been payable under Paragraph 9 above

for cause or the Executive terminates his employment, the Company's sole
obligation shall be to pay Executive his full base salary through the date of

<PAGE>   8
of the assets of the Company, the Company on behalf of it and its successors
and assigns agrees that such transaction or event will not adversely affect the
Executive's financial interests in, or otherwise result in a dilution of
Executive's rights, whether vested or contingent, with regard to, any of
Executive's options or similar programs in which the Executive is then
participating.

     15.  Approval of Publicity. Company and Executive shall mutually approve
all press releases and other items of publicity with respect to Executive's
employment hereunder.

     16.  Covenants of Executive.

          16.1 Confidential Information. "Confidential Information" shall mean
information and compilations of information relating to Company's business,
Company's owners and Company's non-institutional lenders, provided to Executive
during his employment with Company or to which Executive had access or which he
compiled while an executive, including, but not limited to, information
regarding any operating procedures, finances, financial condition,
organization, executives, agents, and other personnel, business activities,
budgets, plans, objectives, or strategies of Company.

          16.2 Covenant as to Nondisclosure or Use of Confidential Information.
Executive agrees that at all times during the Employment Term hereunder and for
a period of two (2) years (thereafter, he will not, unless required to do so
pursuant to legal process such as a subpoena, disclose to any individual or
business enterprise of any nature, or use for his own personal use or financial
gain, whether individually or on behalf of another person, firm, corporation or
entity, any Confidential Information which Executive has obtained or will
obtain in connection with his employment with Company. Such restrictions shall
not apply to information which has become public prior to such disclosure by
Executive. In the event Executive is required by legal process to disclose any
Confidential Information, he shall give prompt notice thereof to Company to
allow Company to object to such process, obtain a protective order, or take any
other action it deems necessary.

          16.3 Return of Business Records. Upon termination of Executive's
employment, Executive shall promptly, if so requested by Company, return all
documents, records, procedures, books, notebooks, and any other documentation
containing any information pertaining to the Company which includes
Confidential Information, including any and all copies of such documentation,
then in Executive's possession or control regardless of 


<PAGE>   9
whether such documentation was prepared or compiled by Executive, Company,
other executives of Company, representatives, agents, or independent
contractors. Executive acknowledges that all such documentation and copies of
such documentation are and shall at all times remain the sole and exclusive
property of Company.

          16.4 Additional Covenants Protecting the Interests of Company.
Executive agrees that during his employment hereunder, and for a period of one
year thereafter, Executive shall not directly or indirectly, individually, or
together through any other person, firm, corporation or entity, without the
prior written consent of Company, engage in any business with any person or
entity which is a customer or client of Company, or approach, counsel, or
attempt to induce any person who is then in the employ of Company, to leave
their employ, other than Executive's secretary, or employ or attempt to employ
any such person, other than Executive's secretary, or aid or counsel any other
person, firm, corporation, or entity to do any of the above.

          16.5 Post-Employment Cooperation. Executive agrees that, for a period
of two (2) years following his termination of employment under this Agreement,
he shall, upon Company's reasonable request and in good faith and with his best
efforts, subject to his reasonable availability, cooperate and assist Company
in any dispute, controversy, or litigation in which Company may be involved and
with respect to which Executive obtained knowledge while employed by the
Company or any of its affiliates, successors, or assigns, including, but not
limited to, his participation in any court or arbitration proceedings, giving
of testimony, signing of affidavits, or such other personal cooperation as
counsel for Company shall request. Any such activities shall be scheduled, to
the extent reasonably possible, to accommodate Executive's business and
personal obligations at the time. Company shall pay Executive's travel and
incidental out-of-pocket expenses incurred in connection with any such
cooperation, as well as the costs of any attorney Executive engages to advise
him in connection with the foregoing.

          16.6 Remedies. In view of the position of confidence which Executive
will enjoy with Company and the anticipated relationship with the clients,
customers, and executives of Company pursuant to his employment hereunder, and
recognizing both the access to confidential financial and other information
which Executive will have pursuant to his employment, Executive expressly
acknowledges that the restrictive covenants set forth in this Section 16 are
reasonable and necessary in order to protect and maintain the proprietary
interests and other legitimate business interests of Company. Executive further
acknowledges 



<PAGE>   10

that (a) it would be difficult to calculate damages to Company from any breach
of his obligations under this Section 16, (b) that injury to Company from any
such breach would be irreparable and impossible to measure, and (c) that the
remedy at law for any breach or threatened breach of this Section 16 would
therefore be an inadequate remedy and, accordingly, Company shall, in addition
to all other available remedies, be entitled to injunctive and other similar
equitable remedies.

      17.   Dispute Resolution. If a dispute arises between the parties
concerning the interpretation of this Agreement or whether a party is in
violation of this Agreement, including but not limited to claims relating to
termination of this Agreement and definition of "cause", then either party may
deliver a written notice of such dispute to the other party (a "Dispute
Notice"). If such dispute is not resolved by the parties within then (10) days
of the Dispute Notice, then the resolution of the dispute described in the
Dispute Notice shall be determined by an expedited arbitration proceeding
conducted under California law and the labor arbitration rules of the American
Arbitration Association (the "Arbitration") with discovery conducted pursuant
to the provisions of California Code of Civil Procedure Sections 2016 et seq.
Any arbitration proceeding determinations shall be binding on the parties. The
arbitration shall not be used to modify any provision of this Agreement and
shall merely interpret the provisions hereof.

            17.1  Selection and Conduct of Arbitrators. The Arbitration
proceeding shall be conducted by each of the parties appointing a qualified
arbitrator within twenty (20) days of the Dispute Notice. A qualified
arbitrator means a person who has had substantial experience in connection with
matters involving the interpretation of employment agreements and the
operations of companies similar to Company and who is unaffiliated with an
otherwise independent of the parties and their affiliates. The two arbitrators
so selected shall within the succeeding twenty (20) day period after their
selection attempt to reach agreement on the dispute submitted after considering
all of the evidence submitted by the parties. If the arbitrators fail to reach
an agreement within such twenty (20) day period, they shall within five (5)
days thereafter select a third qualified arbitrator. In the event the two
arbitrators are unable to reach agreement on the third arbitrator, then the
parties shall select a third arbitrator from a list of seven arbitrators
provided by the Los Angeles County Office of the American Arbitration
Association with each party having the right to strike names in order until
they either agree on an arbitrator from the list, or until one arbitrator's
name remains on the list. The party with the right to strike the first name
shall be determined by the flip of a coin. Such third arbitrator shall 
<PAGE>   11

determine the resolution of the dispute within the succeeding twenty (20) day
period and such decision shall be final and binding on the parties.

            17.2  Sole and Exclusive Remedy. In consideration of the parties
agreement to submit all disputes hereunder to arbitration, and in further
consideration of minimizing the time and expense of resolving any dispute
pursuant hereto, the arbitration provisions shall be the sole and exclusive
remedy of the parties, and each party expressly waives the right to seek
resolution by any other means or in any other forum.

            17.3  Expiration of Claims. All claims that any other party has
against the other must be presented in writing within one (1) year of the date
the claiming party knew or should have known of the facts giving rise to the
claim, or, with respect to claims related to termination of Executive's
employment, within one (1) year of the date of termination hereunder. Any claim
not brought within said time period shall be waived and forever barred unless
the party against whom such claim is made agrees to waive such time period.

            17.4  Enforceability and Costs. Upon completion of the arbitration,
either party may thereafter unilaterally and immediately cause the other to
comply with the decision made by the arbitration proceeding, and any such
decision may be entered in the Superior Court of the State of California or any
other court having jurisdiction. All arbitration costs during the arbitration
shall be paid equally by the parties until such time as a final decision is
made. Likewise, until such time as a final decision is made, each party shall
bear their own attorneys fees.

      18.   Representations By Executive. Executive represents and warrants
that he is free to enter into and perform each of the terms and conditions of
this Agreement; and that his execution and/or performance of all his
obligations under this Agreement does not and will not violate or breach any
other agreement between Executive and any other person or entity.

      19.   Indemnification. Company shall, to the maximum extent permitted by
law, indemnify, defend, and hold Executive harmless for all claims, demands,
losses, costs, expenses, obligations, liabilities, damages, recoveries, and
deficiencies, including reasonable attorneys' fees, that Executive shall incur
or suffer that arise from, result from, or relate to the discharge of
Executive's duties under this Agreement, except to the extent that Executive
has acted in bad faith or shall be guilty of willful misconduct, fraud, gross
negligence, or a wrongful taking.
<PAGE>   12
      20.   General Provisions.

            20.1  Further Assurances. The parties agree that, at any time and
from time to time during the Employment Term, they will take any action and
execute and deliver any document which any other party reasonably requests in
order to carry out the purposes of this Agreement.

or written evidence of delivery. A party may change the address at which
Notice is to be given, at any time and from time to time, by giving Notice of
the new address to the other parties in accordance with this Section.

inures to the benefit of the parties and their respective heirs, executors,
administrators, personal representatives, successors, and assigns. Company may
assign its rights or delegate its duties under this Agreement at any time and
from time to time. However, the parties acknowledge that the availability of
Executive to perform services was a material consideration for Company to enter
into this Agreement. Accordingly, Executive may not assign any of his rights or
delegate any of his duties under this Agreement, either voluntarily or by
operation of law, without the prior written consent of Company, which may be
given or withheld by Company in its sole and absolute discretion. Company
agrees to require any successor to all or substantially all of its business
and/or assets, whether direct or indirect, by agreement in form and substance
reasonably satisfactory to Executive, to assume and agree to perform this
Agreement in the same manner and extent as Company would be required to perform
had no such succession taken place.

        20.6 Applicable Law; Choice of Forum. This Agreement has been made and
executed under, and will be construed and interpreted in accordance with, the
laws of the State of California. Subject to Paragraph 17 above regarding
Dispute Resolution, the parties consent to the jurisdiction of the courts of
the State of California located in Los Angeles County and the United States
District Courts located in the Central District of the State of California in
any action or proceeding arising out of this Agreement, and agree that in those
actions or proceedings, venue will be proper in Los Angeles County (if the
action or proceeding is brought in the Superior Court of California) or in the
Central District of California (if the action or proceeding is brought in the
United States District Court).

        20.7 Attorneys' Fees. In any action or proceeding to enforce or
interpret this Agreement, or arising out of this Agreement, the prevailing

<PAGE>   14
        20.8    Provisions Severable. Every provision of this Agreement is
intended to be severable from every other provision of this Agreement. If any
provision of this Agreement is held to be void or unenforceable, in whole or in
part, the remaining provisions will remain in full force and effect, unless the
remaining provisions are so eviscerated by such holding that they do not reflect
the intent of the parties in entering into this Agreement. If any provision of
this Agreement is held to be unreasonable or excessive in scope or duration,
that provision will be enforced to the maximum extent permitted by law.

        20.9    Non-Waiver of Rights and Breaches. Any waiver by a party of any
breach of any provision of this Agreement will not be deemed to be a waiver of
any subsequent breach of that provision, or of any subsequent breach of that
provision, or of any breach of any other provision of this Agreement. No
failure or delay in exercising any right, power, or privilege granted to a
party under any provision of this Agreement will be deemed a waiver of that or
any other right, power, or privilege. No single or partial exercise of any
right, power, or privilege granted to a party under any provision of this
Agreement will preclude any other or further exercise of that or any other
right, power, or privilege.

                              which results in material injury to the company.

                         d.   You will be entitled to the benefits provided to

          each by written notice to you not less than 90 days prior to the end
          of the one year term. In the event the company does not give you
          notice of renewal for an additional year, you shall be given adequate
          time during the final three months of the term to seek additional
          employment.

     5.   Confidentiality. All confidential information acquired by you with
          respect to Nextera will not be disclosed to any person or used by you
          for personal gain for a period of 2 years following the termination
          of employment.

          In addition, up to one year after the termination of employment, you
          will not engage in business with any person or entity which is a
          customer or client of Nextera or counsel or attempt to induce any
          employee of Nextera to leave their employ.

                              EMPLOYMENT AGREEMENT

          This AGREEMENT (the "Agreement") is made as of August 31, 1998 (the
"Effective Date"), by and between SC/NE, LLC, a Delaware limited liability
company with its headquarters located in New York, New York (the "Company"), and
Roger Brossy (the "Executive"). In consideration of the mutual covenants
contained in this Agreement, the Company and the Executive agree as follows:

     1. EMPLOYMENT. Commencing on the Effective Date, the Company agrees to
employ the Executive and the Executive agrees to be employed by the Company on
the terms and conditions set forth in this Agreement.

     2. CAPACITY. During the Term (as hereinafter defined), the Executive shall
initially serve the Company as the Senior Managing Principal. The Executive
shall also serve the Company in such other or additional offices as the
Executive may be requested by the Leadership Council of the Company. In such
capacity or capacities, the Executive shall perform such services and duties in
connection with the business, affairs and operations of the Company consistent
with his status as a Principal as may be assigned or delegated to the Executive
from time to time by or under the direction and supervision of the Leadership
Council. The Company will not provide any financial consulting services which
could result in it being defined as an Investment Advisor, as defined in Section
202(a)(ii) of the Investment Advisors Act of 1940 or Section 2(a)(20) of the
Investment Company Act of 1940; an Investment Company as defined in Section 3(a)
of the Investment Company Act; or a Broker or Dealer as defined in Sections
3(a)(4) or 3(a)(5) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act").

     3. TERM. Subject to the provisions of Section 6, the term of employment
under this Agreement (the "Term") shall be for two (2) years from the Effective
Date and shall automatically renew for periods of one (1) year commencing at the
second anniversary of the Effective Date and on each subsequent anniversary
thereafter, unless either the Executive or the Company, acting through its
Leadership Council, gives written notice to the other not less than sixty (60)
days prior to the date of any such anniversary of such party's election not to
extend the Term or, if at such time Nextera Enterprises, L.L.C., a Delaware
limited liability company ("Nextera"), has a policy of not extending employment
agreements to all or a designated class (reasonably consistent with business
operations) of its executives into which the Executive falls, Nextera may give
the written nonrenewal notice as described above. In the event Nextera so elects
to not renew this Agreement and the Executive's employment is not terminated,
thereafter the Executive shall be entitled to the severance benefits which
Nextera has reasonably implemented as a firm-wide policy for all or most of its
executives; provided, however, that such severance benefits shall not be
materially inconsistent with the severance benefits that had been provided under
this Agreement in the case of nonrenewal by the Company.

     4. COMPENSATION AND BENEFITS. The regular compensation and benefits payable
to the Executive under this Agreement shall be as follows:

          (a) SALARY. During the Term for all services rendered by the Executive
under this Agreement, the Company shall pay the Executive a salary (the
"Salary") at the annual rate of 


<PAGE>   2


Two Hundred Fifty Thousand Dollars ($250,000) subject to increase from time to
time at the discretion of the Leadership Council or the Compensation Committee
of the Leadership Council (the "Compensation Committee"). The Salary shall be
payable in periodic installments in accordance with the Company's usual practice
for its senior executives.

          (b) BONUS. The Executive shall be entitled to participate in the
Annual Incentive Plan to be adopted by the Company as of the date hereof in the
form attached as "SCHEDULE 1" hereto and in any successor annual incentive
programs if established by the Company. The Executive's annual bonus shall be
determined under the Annual Incentive Plan, and the Executive shall have an
initial annual target bonus equal to sixty percent (60%) of his annual Salary.

          (c) REGULAR BENEFITS. The Executive shall also be entitled to
participate in the plans listed on "SCHEDULE 2" hereto and any other employee
benefit plans, medical insurance plans, life insurance plans, disability income
plans, retirement plans, pension plans, profit sharing plans, vacation plans,
expense reimbursement plans and other benefit plans which the Company, may from
time to time have in effect for all or most of its senior executives
(collectively, "Benefits"). Such participation shall be subject to the terms of
the applicable plan documents, generally applicable policies of the Company,
applicable law and the discretion of the Leadership Council, the Compensation
Committee or any administrative or other committee provided for in or
contemplated by any such plan. Nothing contained in this Agreement shall be
construed to create any obligation on the part of the Company to establish any
such plan or to maintain the effectiveness of any such plan which may be in
effect from time to time, provided, however, the Benefits offered to the
Executive shall be substantially similar to those Benefits extended to the
Executive by Sibson & Company, L.P., a Delaware limited partnership (the
"Partnership") immediately prior to the date hereof, provided further that at
any time (i) Nextera may in its sole discretion cause the Company (A) to modify
or terminate any Benefits provided to the Executive as Nextera deems necessary
to provide that any employee Benefit plan and related trust intended to be
qualified and exempt under Sections 401(a) and 501(a) of the Internal Revenue
Code of 1986, as amended, respectively, shall be so qualified and exempt, or (B)
to otherwise comply with the applicable requirements of the Employee Retirement
Income Security Act of 1974, as amended (or other applicable law) and (ii) the
Leadership Council may terminate such Benefits in its discretion. In the event
that any Benefits are terminated or materially reduced pursuant to clause (i)
above, the Company shall provide the Executive with other Benefits or one or
more cash payments which in the aggregate on an after-tax basis are equal to the
value of such terminated or materially-reduced Benefits through the date of the
Executive's termination of employment.

          (d) PAST SERVICE. The Executive shall be credited with all past
service with the Partnership in the calculation of all benefits and for all
other relevant purposes whatsoever where past service or seniority shall be
considered, subject to any regulatory limitations. For purposes of the preceding
sentence, the Executive shall be deemed to have begun employment with the
Company on the date the Executive began employment with the Partnership or its
predecessors, as applicable.

          (e) OTHER INTEREST.


<PAGE>   3


          (i) The Company, Nextera and the Executive agree that on the Effective
     Date Nextera shall issue and the Executive shall purchase 1,554 Class A
     Common Units of Nextera (the "Class A Common Units") at a purchase price of
     $0.14 per Class A Common Unit. Such Class A Common Units are referred to
     herein as "Purchased Units" and individually as a "Purchased Unit." Nextera
     hereby represents and warrants that the Purchased Units to be sold to the
     Executive have been duly authorized, and when issued to and paid for by the
     Executive will be validly issued, fully paid and nonassessable.

          Within 30 days from the Effective Date (the "Valuation Date"), the
     Executive and Nextera shall agree on the fair market value of such
     Purchased Units (the "Agreed Value"). Within 15 days of the Valuation Date,
     Nextera shall pay to the Executive, as a compensation bonus, cash in an
     amount equal to the Executive's federal, state, and local income tax on the
     portion of the Agreed Value of such Purchased Units which is in excess of
     $.70 per Purchased Unit (the "Excess Value"). The Executive's federal,
     state, and local income tax on the Excess Value shall be computed by taking
     into account the highest personal income tax rate on ordinary income for
     federal purposes and for the state and locality where the Executive has his
     tax home, taking into consideration the deduction for federal income tax
     purposes of the state and local income taxes paid, and, if applicable, the
     deduction for state income tax purposes of the local income taxes paid.
     Additionally, on the same date that the compensation bonus described above
     is paid to the Executive, Nextera shall pay to the Executive, as an
     additional compensation bonus, the amount of cash necessary to "gross-up"
     the compensation bonus described above such that after the Executive pays
     his federal, state, and local income taxes on the two compensation bonuses,
     he will have enough cash remaining to pay his federal, state, and local
     income tax on the Excess Value. If any taxing authority challenges the
     Agreed Value, then Nextera shall indemnify Executive for (i) any reasonable
     costs and expenses incurred in defending against such challenge and (ii)
     any additional tax liability incurred by Executive (including any interest
     and penalties) if such challenge results in a higher value of such
     Purchased Units than the Agreed Value, and such indemnification shall be
     "grossed-up" using the "gross-up" procedure described directly above.

          (ii) The Executive represents as of the date hereof that the Executive
     is an "accredited investor" as such term is defined by Rule 501 promulgated
     under the Securities Act of 1933, as amended (the "Securities Act"). The
     Executive has substantial experience in evaluating and investing in private
     placement transactions of securities in companies similar to Nextera so
     that he is capable of evaluating the merits and risks of acquiring
     Purchased Units in connection with this Agreement and has the capacity to
     protect his own interests. The Executive must bear the economic risk of
     holding the Purchased Units indefinitely unless such securities are
     registered pursuant to the Securities Act, or an exemption from
     registration is available for the disposition thereof.

          (iii) The Executive is acquiring the Purchased Units for his own
     account for investment only, and not with the view to, or for resale in
     connection with, any distribution thereof. It understands that the
     Purchased Units acquired have not been, and will not be, registered under
     the Securities Act by reason of a specific exemption from the registration
     provisions of the Securities Act, the availability of which depends


<PAGE>   4


     upon, among other things, the bona fide nature of the investment intent and
     the accuracy of the Executive's representations as expressed herein.

          (iv) The Executive understands that no public market now exists for
     any of the securities issued by Nextera and that Nextera has not made any
     assurances that a public market will ever exist for such securities.

          (v) The Executive has received and read the Nextera Operating
     Agreement, Nextera business plan and financial statements and has had an
     opportunity to discuss Nextera's business, management and financial affairs
     with its management. The Executive has also had an opportunity to ask
     questions of and receive answers from officers of Nextera regarding the
     terms and conditions of acquiring the Purchased Units, which questions were
     answered to the Executive's satisfaction.

          (vi) The residence of the Executive in which his investment decision
     was made is set forth next to the Executive's name on the signature page
     hereto.

          (vii) Additionally, the Executive may participate in any additional
     option or similar incentive plans which the Company and/or Nextera shall
     have in effect from time to time for the benefit of all or most of its
     executive employees.

          (f) VACATION. The Executive's vacation entitlement shall be the same
as the policy of the Partnership immediately prior to the date hereof.

          (g) TAXATION OF PAYMENTS AND BENEFITS. The Company shall undertake to
make deductions, withholdings and tax reports with respect to payments and
Benefits under this Agreement to the extent that it reasonably and in good faith
believes that it is required to make such deductions, withholdings and tax
reports. Payments under this Agreement shall be in amounts net of any such
deductions or withholdings. Nothing in this Agreement shall be construed to
require the Company to make any payments to compensate the Executive for any
adverse tax effect associated with any payments or benefits or for any deduction
or withholding from any payment or benefit.

          (h) EXCLUSIVITY OF SALARY AND BENEFITS. The Executive shall not be
entitled to any payments or benefits other than those provided under this
Agreement (other than customary business expense reimbursements submitted and
approved in accordance with Company policy).

     5. EXTENT OF SERVICE. During the Executive's employment under this
Agreement, the Executive shall, subject to the direction and supervision of the
Leadership Council or the Senior Managing Principal, devote substantially all of
the Executive's business time, and use his best efforts and business judgment,
skill and knowledge to the advancement of the Company's interests and to the
discharge of the Executive's duties and responsibilities under this Agreement.
The Executive shall not engage in any other business activity, except as may be
approved by the Leadership Council which approval shall not be unreasonably
withheld; provided that nothing in this Agreement shall be construed as
preventing the Executive from:

          (a) investing the Executive's assets in any company or other entity in
a manner not prohibited by the Non-Compete, Non Solicitation, Proprietary
Information, 


<PAGE>   5


Confidentiality and Inventions Agreement referred to in Section 7(a) and in such
form or manner as shall not require any material activities on the Executive's
part in connection with the operations or affairs of the companies or other
entities in which such investments are made; or

          (b) engaging in religious, charitable or other community or non-profit
activities that do not materially impair the Executive's ability to fulfill the
Executive's duties and responsibilities under this Agreement.

     6. TERMINATION AND TERMINATION BENEFITS. Notwithstanding the provisions of
Section 3, the Executive's employment under this Agreement shall terminate under
the following circumstances set forth in this Section 6.

          (a) Termination by the Company for Cause.

               (i) The Executive's employment under this Agreement may be
          terminated for cause without further liability on the part of the
          Company effective immediately upon a vote of the Leadership Council
          and written notice to the Executive. Subject to Section 6(h), only the
          following shall constitute "cause" for such termination:

                    (A) material dishonest statements or acts of the Executive
               with respect to the Company or any affiliate of the Company;

                    (B) conviction of the Executive for (x) a felony or (y) any
               misdemeanor involving moral turpitude, deceit, dishonesty or
               fraud; or

                    (C) willful and material breach of this Agreement by the
               Executive, gross negligence, willful misconduct or willful
               failure or refusal of the Executive to comply with explicit
               directions of the Leadership Council which directions are
               consistent with Section 2 of this Agreement, in each instance
               after fifteen (15) days written notice and an opportunity to
               cure.

               (i) In making any determination under this Section 6(a), the
          Leadership Council shall act fairly and in good faith and shall give
          the Executive an opportunity to appear and be heard at a meeting of
          the Leadership Council and present evidence on his behalf.

          (b) TERMINATION BY THE EXECUTIVE. The Executive's employment under
this Agreement may be terminated by the Executive by written notice to the
Leadership Council at least sixty (60) days prior to such termination.

          (c) TERMINATION BY THE COMPANY WITHOUT CAUSE OR BY THE EXECUTIVE WITH
GOOD REASON. Subject to the payment of Termination Benefits pursuant to Section
6(d), the Executive's employment under this Agreement may be terminated by the
Company without cause upon written notice to the Executive by a vote of the
Leadership Council or by the Executive with Good Reason (as defined in Section
8(b)) upon written notice to the Leadership Council.

          (d) CERTAIN TERMINATION BENEFITS. Unless otherwise specifically
provided in 


<PAGE>   6


this Agreement or otherwise required by law, all compensation and benefits
payable to the Executive under this Agreement shall terminate on the date of
termination of the Executive's employment under this Agreement. Notwithstanding
the foregoing, in the event of termination of the Executive's employment with
the Company pursuant to Section 6(c) above or Section 6(g) below, the Company
shall provide to the Executive the following termination benefits ("Termination
Benefits"):

               (i) continuation of the Executive's Salary at the rate then in
          effect pursuant to Section 4(a); and

               (ii) (A) a bonus for the year in which the termination occurs pro
          rata for the period of service in such year, based upon the bonus
          amount, if any, paid to the Executive pursuant to the Annual Incentive
          Plan described in Section 4(b) for the year preceding the year in
          which the termination of employment occurs, or if the termination
          occurs prior to the initial determination of a bonus pursuant to the
          Annual Incentive Plan, based upon the bonus paid to the Executive by
          the Partnership for the year ended December 31, 1997 (such applicable
          amount being the "Applicable Bonus") and (B) payments at an annual
          rate based upon the Applicable Bonus to be paid monthly during the
          period set forth in subsection (iv) below; and

               (iii) continuation of all Benefits to the extent authorized by
          and consistent with 29 U.S.C. ss.1161 et seq. (commonly known as
          "COBRA"), with the cost of the regular premium for such Benefits
          shared in the same relative proportion by the Company and the
          Executive as in effect on the date of termination.

               (iv) The Termination Benefits set forth in (i), (ii)(B) and (iii)
          above shall continue effective until the later of (x) the expiration
          of the initial Term assuming employment of the Executive had not been
          terminated for the initial two-year period of this Agreement (but not
          including any renewals that have not yet occurred) or (y) one (1) year
          from the date of the termination of the Executive's employment and
          will include such payments for accrued vacation pay and any similar
          items required by law. Notwithstanding the foregoing, nothing in this
          Section 6(d) shall be construed to affect the Executive's right to
          receive COBRA continuation entirely at the Executive's own cost to the
          extent that the Executive may continue to be entitled to COBRA
          continuation after the Executive's right to cost sharing under Section
          6(d)(iii) ceases.

               (v) In the event of the termination of the Executive's employment
          with the Company pursuant to Section 6(c) above any options
          exercisable for Class A Common Units granted to the Executive under
          the Executive's Equity Participation Agreement which are not vested at
          that time shall be deemed to have vested to the extent of fifty
          percent (50%) of such remaining unvested portion.

              In addition to the foregoing, in the event of the termination of 
the Executive's employment with the Company for any reason, the Executive shall
be entitled to payment of any accrued and unpaid Benefits for which the
Executive may otherwise be vested or entitled in accordance with the terms of
the applicable plans governing such Benefits and to payment for reimbursable
expenses under applicable Company policy within thirty (30) days of termination.


<PAGE>   7


          (e) DISABILITY. At the election of the Leadership Council, this
Agreement shall terminate on such date as may be selected by the Leadership
Council after the Executive shall have failed to render and perform the services
required of him under this Agreement during any period of 90 days within any 120
day period during the Term because of physical or mental disability. In the
event of such termination, the Company shall have no further obligation for the
payment of compensation or benefits hereunder, except (i) for compensation
accrued and unpaid through the termination date and (ii) the payment of any
disability insurance to which the Executive may be entitled. If there should be
any dispute between the parties as to the Executive's physical or mental
incapacity or disability pursuant to this Section 6(e), such question shall be
settled by the opinion of an impartial reputable physician agreed upon for this
purpose by the parties or their representatives, or failing agreement within ten
(10) days after a written request therefor by any party to the other party, one
selected in accordance with the rules of the American Arbitration Association.
The certificate of such physician as to the matter in dispute shall be final and
binding on the parties.

          (f) DEATH. In the event of termination as a result of the Executive's
death, the Company shall have no further obligation to the Executive's
representatives and heirs hereunder.

          (g) FAILURE TO RENEW AGREEMENT. In the event the Company or Nextera
elects not to extend the term of this Agreement as permitted by Section 3 and
the Executive's employment is terminated, (i) that portion of Executive's
options exercisable for Class A Common Units granted to the Executive under the
Executive's Equity Participation Agreement which are not vested at that time
shall be deemed to have vested to the extent of fifty percent (50%) of such
remaining unvested portion, and (ii) the Executive shall be entitled to the
other Termination Benefits described in Section 6(d).

          (h) LEAVE OF ABSENCE UPON INDICTMENT. Upon indictment of the Executive
for (A) a felony or (B) any misdemeanor involving moral turpitude, deceit,
dishonesty or fraud ("indictment," for these purposes, meaning an indictment,
probable cause hearing or any other procedure pursuant to which an initial
determination of probable or reasonable cause with respect to such offense is
made), the Leadership Council, at its option, may place the Executive on a paid
leave of absence from employment for a period of up to six (6) months from such
election. At the end of the six (6) month period if the indictment is pending,
the Leadership Council may terminate the Executive for "cause" effective
immediately upon a vote of the Leadership Council and written notice to the
Executive without further liability on the part of the Company. In making any
determination under this Section 6(h), the Leadership Council shall act fairly
and in good faith and shall give the Executive an opportunity to appear and be
heard at a meeting of the Leadership Council or any committee thereof and
present evidence on his behalf.

          (i) REMOVAL FROM OFFICE AS SENIOR MANAGING PRINCIPAL. Notwithstanding
the foregoing, the Executive may be removed from office as Senior Managing
Principal and his employment may be terminated in accordance with the terms and
provisions of Section 3.19 of the Limited Liability Company Agreement of the
Company. Other than as set forth in the Limited Liability Company Agreement of
the Company, any termination of the Executive's employment under this Section
6(i) shall be without further liability on the part of the Company. In the event
the Executive is removed from office as Senior Managing Principal but his
employment is not also terminated, this Agreement shall be terminated and shall
be replaced with


<PAGE>   8


a written employment agreement with substantially similar terms and conditions
(including the then existing Term) as was provided to the Executive hereby,
other than the status of Senior Managing Principal.

     7. NON-COMPETE, NON-SOLICITATION, PROPRIETARY INFORMATION, CONFIDENTIALITY
AND INVENTIONS AGREEMENTS.

          (a) The Executive agrees to sign the Nextera Non-Compete,
Non-Solicitation, Proprietary Information, Confidentiality and Inventions
Agreement, a copy of which is attached hereto as Exhibit "A."

          (b) LITIGATION AND REGULATORY COOPERATION. During the Executive's
employment, the Executive shall cooperate fully with the Company in the defense
or prosecution of any claims or actions now in existence or which may be brought
in the future against or on behalf of the Company or Nextera which relate to
events or occurrences that transpired while the Executive was employed by the
Company, the Partnership or the Partnership's predecessors provided, however,
that the Executive shall be permitted to give testimony and appear as a witness
in any proceeding in which such testimony or appearance is required by law. The
Executive's full cooperation in connection with such claims or actions shall
include, but not be limited to, being available to meet with counsel to prepare
for discovery or trial and to act as a witness on behalf of the Company at
mutually convenient times. During the Executive's employment, the Executive also
shall cooperate fully with the Company in connection with any investigation or
review of any federal, state or local regulatory authority as any such
investigation or review relates to events or occurrences that transpired while
the Executive was employed by the Company. The Executive also agrees to provide
reasonable cooperation to the Company on matters of the type described in this
Section 7(b) after termination of the Executive's employment. The Company shall
reimburse the Executive for any reasonable out-of-pocket expenses incurred in
connection with the Executive's performance of obligations pursuant to this
Section 7(b).

          (c) INJUNCTION. The Executive agrees that it would be difficult to
measure any damages caused to the Company which might result from any breach by
the Executive of the promises set forth in this Section 7, and that in any event
money damages would be an inadequate remedy for any such breach. Accordingly,
the Executive agrees that if the Executive breaches, or proposes to breach, any
portion of this Section 7, the Company shall be entitled, in addition to all
other remedies that it may have, to an injunction or other appropriate equitable
relief to restrain any such breach without showing or proving any actual damage
to the Company.

     8. CHANGE OF CONTROL.

          (a) Change of Control shall mean the occurrence of one or more of the
following events:

               (i) any "person" or "group" (as such terms are used in Sections
          13(d) and 14(d)(2) of the Exchange Act (other than any fiduciary
          holding securities under an employee benefit plan of the Company, any
          member of the KU Control Group (as defined in the Nextera Operating
          Agreement as amended by the First Amendment to the 


<PAGE>   9


          Nextera Operating Agreement (the "First Amendment")), or any
          Controlled Affiliate (as defined in the First Amendment) of the KU
          Control Group (x) becomes a "beneficial owner" (as such term is
          defined in Rule 13d-3 promulgated under the Exchange Act), directly or
          indirectly, of securities of the Company or Nextera, representing
          fifty percent (50%) or more of the combined voting power of the then
          outstanding securities of the Company or Nextera, or (y) has the
          right, directly or indirectly, by ownership of voting securities,
          contract or otherwise, to elect a majority of the members of the Board
          of Directors of Nextera; or

               (ii) persons who, as of the Effective Date, constituted the Board
          of Directors of Nextera (the "Incumbent Board") cease for any reason,
          including without limitation as a result of a tender offer, proxy
          contest, merger or similar transaction, to constitute at least a
          majority of the Board of Directors of Nextera provided that any person
          becoming a member of the Board of Directors of Nextera subsequent to
          the Effective Date whose election was approved by at least a majority
          of the members then comprising the Incumbent Board shall, for purposes
          of this Section 8(ii), be considered a member of the Incumbent Board,
          and further provided that any person or persons becoming a member of
          the Board of Directors of Nextera subsequent to the Effective Date who
          was nominated by the Board of Directors of Nextera or the governing
          body of any Controlled Affiliate of the KU Control Group shall, for
          purposes of this Section 8(ii), be considered a member of the
          Incumbent Board, as applicable; or

               (iii) the members or stockholders of the Company or Nextera
          approve a merger or consolidation of the Company or Nextera with any
          other corporation or other entity, other than (1) a merger or
          consolidation which would result in the voting securities of the
          Company or Nextera outstanding immediately prior thereto continuing to
          represent (either by remaining outstanding or by being converted into
          voting securities of the surviving entity) more than seventy-five
          percent (75%) of the combined voting power of the voting securities of
          the Company or Nextera or such surviving entity outstanding
          immediately after such merger or consolidation or (2) a merger or
          consolidation effected to implement a recapitalization of the Company
          or Nextera (or similar transaction) in which no "person" or "group"
          (as defined in Section 8(a)(i) above) (other than any trustee or other
          fiduciary holding securities under an employee benefit plan of the
          Company, any member of the KU Control Group (as defined in the First
          Amendment), or any Controlled Affiliate of the KU Control Group)
          acquires more than fifty percent (50%) of the combined voting power of
          the Company's or Nextera's then outstanding securities; or

               (iv) the members or stockholders of the Company or Nextera
          approve a plan of complete liquidation of the Company or Nextera or an
          agreement for the sale or disposition by the Company or Nextera of all
          or substantially all of the assets of the Company or Nextera.

               Notwithstanding the foregoing, for purposes of this Agreement,
(i) a transfer (whether pursuant to a sale or otherwise) of all or a portion of
the stock or membership interests of the Company or Nextera or a transfer
(whether pursuant to a sale or otherwise) of all or a portion of the assets of
the Company or Nextera to an entity controlled by or under common control with
Nextera shall not be deemed to be a Change of Control and (ii) the Incorporation


<PAGE>   10


Transaction (as defined in that certain Share Exchange Agreement dated as of the
date hereof by and among Nextera and the other parties named therein) shall not
be deemed to be a Change of Control.

          (b) TERMINATION DUE TO CHANGE OF CONTROL. In the event that during the
period of Executive's active employment with the Company, there is a Change of
Control, as defined above, and within six (6) months of the date upon which
Executive receives notice of the event of Change of Control, Executive's
employment is terminated by the Company without cause or by the Executive for
Good Reason (as defined below), then the Company shall provide the Executive
with the Termination Benefits described in Section 6(d). For purposes of this
Agreement, "Good Reason" shall mean, without the Executive's written consent,
the occurrence of any of the following circumstances:

               (i) the assignment to the Executive of any duties substantially
          inconsistent and adverse with the position of a Principal in the
          Company, without regard to any change with respect to titles or
          special functions (including Senior Managing Principal) that the
          Executive may hold from time to time;

               (ii) in the event of a Change of Control, the assignment to the
          Executive of any duties substantially inconsistent and adverse with
          the position in the Company that the Executive held immediately prior
          to the Change of Control, or a significant adverse alteration in the
          nature or status of the Executive's responsibilities or the conditions
          of the Executive's employment from those in effect immediately prior
          to such Change of Control;

               (iii) the Company's reduction of the Executive's annual base
          salary as in effect on the date hereof or as the same may be increased
          from time to time except for across-the-board salary reductions
          similarly affecting all management personnel of the Company;

               (iv) the relocation of the Company's offices at which the
          Executive is principally employed to a location more than 25 miles
          from such location (or, if the office at which the Executive is
          principally employed is in the Manhattan business district of New
          York, New York, the relocation to a location outside the Manhattan
          business district) or the Company's requiring the Executive to be
          based anywhere other than the Company's offices at such location
          except for required travel on the Company's business to an extent
          substantially consistent with the Executive's present business travel
          obligations;

               (v) the Company's failure to pay to the Executive any portion of
          the Executive's current compensation or to pay to the Executive any
          portion of an installment of deferred compensation under any deferred
          compensation program of the Company within seven (7) days of the date
          such compensation is due;

               (vi) the Company's failure to continue in effect any material
          compensation or benefit plan in which the Executive participates,
          unless an equitable arrangement (embodied in an ongoing substitute or
          alternative plan) has been made with 


<PAGE>   11


          respect to such plan, or the Company's failure to continue the
          Executive's participation therein (or in such substitute or
          alternative plan) on a basis not materially less favorable, both in
          terms of the amount of benefits provided and the level of the
          Executive's participation relative to other participants;

               (vii) the Company's failure to continue to provide the Executive
          with benefits substantially similar to those enjoyed by the Executive
          under any of the Company's life insurance, medical, health and
          accident, or disability plans in which the Executive participates, the
          taking of any action by the Company which would directly or indirectly
          materially reduce any of such benefits, or the failure by the Company
          to provide the Executive with the number of paid vacation days to
          which the Executive are entitled on the basis of years of service with
          the Company in accordance with the Company's normal vacation policy;
          or

               (viii) in the event of a Change of Control, a successor to the
          Company or Nextera does not expressly assume the obligations of the
          Company or Nextera, as applicable, under this Agreement.

          9. REPURCHASE OPTION. Capitalized terms used in this Section 9 and not
otherwise defined in this Agreement shall have the meanings ascribed to such
terms in the Stockholders Agreement and the Nextera Operating Agreement as
amended by the First Amendment.

               The Executive agrees to be bound by Section 6.4 of the Nextera
Operating Agreement and Section 4.4 of the Stockholders Agreement, subject in
each case to the provisions of this Section 9. In the event that Nextera
exercises the Repurchase Option during the period following the Effective Date
of the First Amendment and prior to expiration of the non-solicitation period
(the "Applicable Period") contained in the Executive's Non-Compete,
Non-Solicitation, Proprietary Information, Confidentiality and Inventions
Agreement (the "Non-Solicitation Agreement"), if the Executive does not breach
any provision of this Agreement or the Non-Solicitation Agreement, then the
Executive shall not be required to sell such Units to Nextera. At such time
within the Applicable Period that the Executive breaches any provision of this
Agreement or the Non-Solicitation Agreement, the Applicable Period shall
immediately terminate. At the termination of the Applicable Period (either by
way of the lapse of the applicable time period or the breach by the Executive of
any provision of this Agreement or the Non-Solicitation Agreement) the terms of
this Section 9 shall no longer apply to the Executive and the terms of Section
6.4 of the Nextera Operating Agreement or Section 4.4 of the Stockholders
Agreement, as applicable, without reference to this Section 9, shall apply to
the Executive except that the six month Repurchase Option Period shall be deemed
to have begun on the termination of the Applicable Period. At such time as the
business of Nextera is incorporated, provisions having the same effect as the
provisions of this Section 9 concerning the Repurchase Option shall apply to any
securities of the newly-incorporated entity issued to the Executive in exchange
for his Units in Nextera, provided, however, that such Repurchase Option shall
terminate upon a Qualified Initial Public Offering.

          10. GENERAL.

               (a) ARBITRATION OF DISPUTES. Any controversy or claim arising out
of or 


<PAGE>   12


relating to this Agreement or the breach thereof or otherwise arising out of the
Executive's employment or the termination of that employment (including, without
limitation, any claims of unlawful employment discrimination whether based on
age or otherwise) shall, to the fullest extent permitted by law, be settled by
arbitration in any forum and form agreed upon by the parties or, in the absence
of such an agreement, under the auspices of the American Arbitration Association
("AAA") in the state where Executive performs substantially all of his duties in
accordance with the Employment Dispute Resolution Rules of the AAA, including,
but not limited to, the rules and procedures applicable to the selection of
arbitrators, except that the arbitrator shall apply the law as established by
decisions of the U.S. Supreme Court and the federal and state courts sitting in
the state where Executive performs substantially all of his duties in deciding
the merits of claims and defenses under federal law or any state or federal
anti-discrimination law, and any awards to the Executive for violation of any
anti-discrimination law shall not exceed the maximum award to which the
Executive could be entitled under the applicable (or most analogous)
anti-discrimination or civil rights laws. In the event that any person or entity
other than the Executive or the Company may be a party with regard to any such
controversy or claim, such controversy or claim shall be submitted to
arbitration subject to such other person or entity's agreement. Judgment upon
the award rendered by the arbitrator may be entered in any court having
jurisdiction thereof. The arbitrator shall have the authority to grant the
prevailing party reasonable costs and expenses, including reasonable attorney's
fees and the costs of the arbitration. This Section 10(a) shall be specifically
enforceable. Notwithstanding the foregoing, this Section 10(a) shall not
preclude either party from pursuing a court action for the sole purpose of
obtaining a temporary restraining order or a preliminary injunction in
circumstances in which such relief is appropriate; provided that any other
relief shall be pursued through an arbitration proceeding pursuant to this
Section 10(a).

               (b) INTEGRATION. This Agreement constitutes the entire agreement
between the parties with respect to the subject matter hereof and supersedes all
prior understandings and agreements between the parties, whether oral or
written, with respect to any related subject matter.

               (c) ASSIGNMENT: SUCCESSORS AND ASSIGNS, ETC. Neither the Company
nor the Executive may make any assignment of this Agreement or any interest
herein, by operation of law or otherwise, without the prior written consent of
the other party provided that the Company may assign its rights under this
Agreement without the consent of the Executive in the event that the Company
shall effect a reorganization, consolidate with or merge into any other
corporation, partnership, organization or other entity, or transfer all or
substantially all of its properties or assets to any other corporation,
partnership, organization or other entity; provided such successor is the
functional equivalent of the Company. This Agreement shall inure to the benefit
of and be binding upon the Company and the Executive, their respective
successors, executors, administrators, heirs and permitted assigns.

               (d) ENFORCEABILITY. If any portion or provision of this Agreement
(including, without limitation, any portion or provision of any section of this
Agreement) shall to any extent be declared illegal or unenforceable by a court
of competent jurisdiction, then that court shall have the power to alter such
provision to make it enforceable to the fullest extent permitted by law. The
remainder of this Agreement, or the application of such portion or provision in
circumstances other than those as to which it is so declared illegal or
unenforceable, shall not be

affected thereby, and each portion and provision of this Agreement shall be
valid and enforceable to the fullest extent permitted by law.

               (e) WAIVER. No waiver of any provision hereof shall be effective
unless made in writing and signed by the waiving party. The failure of any party
to require the performance of any term or obligation of this Agreement, or the
waiver by any party of any breach of this Agreement, shall not prevent any
subsequent enforcement of such term or obligation or be deemed a waiver of any
subsequent breach.

               (f) NOTICES. Any notices, requests, demands and other
communications provided for by this Agreement shall be sufficient if in writing
and delivered in person or sent by a nationally recognized overnight courier

a written instrument signed by the Executive and by a duly authorized
representative of the Company.

               (h) COUNTERPARTS. This Agreement may be executed in any number of
counterparts, each of which when so executed and delivered shall be taken to be
an original; but such counterparts shall together constitute one and the same
document.

          11. CONSENT TO JURISDICTION.

             NONCOMPETE, NON-SOLICITATION, PROPRIETARY INFORMATION,
                    CONFIDENTIALITY AND INVENTIONS AGREEMENT

        This Agreement is made as of August 31, 1998, by and between Nextera
Enterprises, L.L.C., a Delaware limited liability company, and the undersigned
Executive. In consideration of the employment and continued employment of
Executive by Nextera Enterprises L.L.C., its successors, subsidiaries and
affiliates (collectively, "Nextera"), the Executive agrees to certain
restrictions on activities necessary to avoid conflicts of interest, ensure the
exclusivity of Executive's services and protect the goodwill, confidential
information, and legitimate business interests of Nextera and its clients. To
further these objectives, the Executive agrees to comply with the following
provisions of this Agreement ("Agreement") as follows:

NONCOMPETE/EXCLUSIVITY

        1.     During the period of employment by Nextera:

               (a)     the Executive will devote substantially all of the
                       Executive's business time to the business of Nextera in
                       accordance with Section 5 of the Executive's Employment
                       Agreement with SC/NE, LLC of even date herewith;

               (b)     will not engage in any business activity, current or
                       proposed, which competes with the services or products
                       being developed, marketed or sold by Nextera;

               (c)     will not, without prior written consent of Nextera,
                       invest in, enter into or assist any venture, enterprise,
                       or endeavor which competes or intends to compete with
                       Nextera, other than as a less than five percent (5%)
                       stockholder of a publicly held company or a stockholder
                       of a publicly held company which derives none or an
                       immaterial portion (i.e., less than ten percent (10%)) of
                       its revenues from services which compete with the
                       services of Nextera

        2.     The Executive represents that, to the best of the Executive's
               knowledge, employment by Nextera will not conflict with any
               agreement to which the Executive is subject.

NON-SOLICITATION

        1.     The Executive acknowledges that the names and details of the
               firms with whom he has dealings while employed by Nextera
               constitute trade secrets belonging to Nextera. In order to
               preserve Nextera's trade secrets, during employment with Nextera
               and for a period of two years after termination of the
               Executive's employment with Nextera for any reason:




                                       1



<PAGE>   2

               (a)     the Executive will not solicit or cause to be solicited,
                       or aid in the solicitation of business from firms for
                       which the Executive did work or from whom the Executive
                       actively solicited business during the Executive's
                       employment with Nextera or any of its subsidiaries or
                       affiliates;

               (b)     the Executive will not directly or indirectly contact or
                       solicit any employee of Nextera with regard to present,
                       future or contemplated employment opportunities on behalf
                       of himself, or any other person, firm, corporation,
                       governmental agency or other entity.

PROPRIETARY INFORMATION

        1.     Proprietary Information refers to any information, not generally
               known in the relevant trade or industry, which was obtained from
               Nextera or any of its clients, past, present, or prospective,
               other than information that is or becomes known to the public or
               trade through no breach of this Agreement by the Executive.

        2.     Proprietary Information includes, but is not limited to, the
               following items, whether or not labeled as such: customer lists,
               notes, drawings and writings; computer programs (including source
               and object codes), algorithms, systems, tools, spreadsheets,
               related documentation such as user manuals, functional and
               technical specifications, system descriptions, program
               documentation, output reports, terminal displays, and data file
               contents; plans, process and preparations for Nextera's current
               and proposed business activities; discoveries, inventions,
               developments, ideas, research, engineering, designs, and
               products; projects and improvements made or conceived in
               connection with Nextera's customer and prospective customer's
               lists; and marketing and financial data of Nextera and its
               clients.

        3.     The Executive agrees not to disclose the existence of or contents
               of any documents, records, discs, tapes, and other media that
               contain Proprietary Information, and will not copy or remove any
               such material from Nextera or its client's premises, except as
               required by the Executive's duties or as approved by an
               authorized officer of Nextera.

        4.     The Executive agrees to comply with all restrictions and
               regulations of Nextera's clients concerning any and all
               information such clients deem proprietary or confidential.

        5.     The Executive agrees that any material relating to any matter
               within the scope of the business of Nextera, and any materials of
               clients of Nextera, is and shall remain the property of Nextera
               or such clients, as the case may be, and that upon termination of
               employment or at any earlier time as requested by Nextera, the
               Executive will immediately deliver such material and all copies
               in Executive's possession or control to Nextera or such clients,
               as the case may be.



                                       2



<PAGE>   3

        6.     Nextera may provide the Executive with equipment (portable
               personal computer, software, etc.) for Executive's use in the
               course of employment by Nextera. The Executive acknowledges that
               any such equipment will remain the exclusive property of Nextera,
               and the Executive agrees to deliver such equipment to Nextera, as
               directed by Nextera, upon termination of employment for any
               reason, or at any time upon request of Nextera.

CONFIDENTIALITY

        1.     Except in connection with the Executive's duties for Nextera, the
               Executive will not use or disclose to anyone outside Nextera, and
               will not use any Proprietary Information or material relating to
               the business of Nextera, or its clients, either during or after
               employment by Nextera, except with the written permission of
               Nextera.

        2.     The Executive will not disclose to Nextera, and will not induce
               Nextera to use any confidential information or material belonging
               to others where such disclosure would, to the Executive's
               knowledge, violate any rights of, or any duty owing to, a third
               party.

        3.     The Executive agrees not to discuss any information or respond to
               any inquiries from the press or other information agencies
               regarding Nextera without the express permission of Nextera,
               other than responding in the ordinary course of business to
               inquiries regarding the consulting industry generally or work
               done for clients of SC/NE, LLC.

        4.     The Executive shall be permitted to give testimony and appear as
               a witness in any proceeding in which such testimony or appearance
               is required by law, provided the Executive reasonably furnishes
               notice to Nextera in order to enable Nextera to seek a protective
               order, if applicable.

INVENTIONS

        1.     The Executive agrees to disclose promptly and fully to Nextera
               all developments, inventions, discoveries, improvements, and
               proposals for new programs, systems, services, products, tools,
               or business endeavors which are related to any business activity
               by Nextera, current or proposed (collectively called
               "Developments").

        2.     The Executive hereby assigns to Nextera the Executive's entire
               right, title, and interest in each and every work product or
               Development related to any business activity by Nextera, current
               or proposed (collectively called "Work Product"):

               (a)     made, developed or conceived solely by the Executive or
                       jointly with others during or in the course of the
                       Executive's employment by Nextera,



                                       3




<PAGE>   4

               (b)     made, developed or conceived wholly or partially as the
                       result of any task assigned to the Executive or any work
                       performed by the Executive for or on behalf of Nextera or
                       its clients, and/or

               (c)     made or developed with the use of Nextera facilities or
                       equipment.

        3.     The Executive agrees to grant to Nextera a right of first refusal
               to market on a mutually agreed royalty basis, and a perpetual
               non-exclusive license to use, each and every Work Product or
               Development made, developed or conceived by the Executive during
               employment by Nextera which is not covered under the preceding
               paragraph.

        4.     During employment with Nextera, the Executive agrees to provide
               Nextera with copies of any manuscripts produced by the Executive
               relating to the business of Nextera or which refers to Nextera in
               any manner for approval by Nextera prior to submission for
               publication.

        5.     The Executive does not, however, assign any Developments, if any,
               relating in any way to Nextera business which were made prior to
               employment with Nextera, which Developments, if any, are
               identified on Exhibit A, attached to this Agreement.

GENERAL

        1.     The Executive's obligations under this Agreement shall survive
               the termination of employment. The Executive understands that
               this Agreement does not create an obligation of Nextera or any
               other party to continue employment.

        2.     Nextera shall have the unrestricted right to assign this
               Agreement to its parent company, its affiliates, and any and all
               successors in interest.

        3.     It is agreed that Nextera may inform any person or entity
               subsequently employing or evidencing an intention to employ,
               Executive of the nature of the information Nextera asserts to be
               confidential, and may inform said person or entity of the
               existence of this Agreement, and provide to such persons or
               entity a copy of this Agreement.

        4.     Any breach of this Agreement by the Executive may cause
               irreparable damage, and in the event of such a breach, Nextera
               shall have, in addition to any remedies at law, the right to an
               injunction to prevent or restrain a breach of the Executive's
               obligations hereunder.

        5.     Nextera's failure to exercise any rights under this Agreement
               does not constitute a waiver of such right in the event of a
               subsequent violation of this Agreement.



                                       4



<PAGE>   5

        6.     This Agreement shall be governed by the laws of the state of
               Executive's employment.

        7.     In the event a court of competent jurisdiction shall determine
               that any provision in this Agreement is too restrictive in scope
               or duration, then that court shall have the power to alter such
               provision to make it enforceable to the fullest extent permitted
               by law. Such a determination shall not have the effect of
               rendering any other provision herein contained invalid.

NOTICE TO BORROWER:                  THIS DOCUMENT CONTAINS
                                     PROVISIONS WHICH REQUIRE A
                                     BALLOON PAYMENT AT MATURITY.


                                PROMISSORY NOTE

$576,000                                                         January 2, 1998


          1.   For value received, Gresham Brebach, Jr. ("Borrower"), promises
to pay to the order of Nextera Enterprises Holdings, L.L.C., a Delaware limited
liability company, or its assigns ("Lender"), the sum of Five Hundred
Seventy-Six Thousand Dollars ($576,000), or such lesser sum as shall be advanced
by Lender to Borrower hereunder from time to time (the "Principal Amount"), with
interest on the unpaid balance of such amount from the date of the initial
disbursement of the loan (the "Loan") evidenced hereby, at the rate of interest
specified herein. This Note is secured by the security interest in Borrower's
interest in Enterprise Holdings, L.L.C., a Delaware limited liability company
("NEH"), granted in the Security Agreement of even date herewith entered into
between Lender and Borrower (the "Security Agreement"). Lender shall record the
amount and date of each advance hereunder on Schedule "A" attached hereto,
provided, however, the failure by Lender to make any such notation shall in no
way affect or impair Borrower's obligations to make all payments due hereunder.

          2.   The Principal Amount hereof shall bear interest at ten percent
(10%) per annum, compounded annually, but in no case shall the interest rate
exceed the maximum rate allowed by law.

          3.   A final payment of the Maturity Obligations (as hereinafter
defined) shall be due and payable upon the first to occur of the following: (i)
the date which is five (5) years from the date of this Note, or (ii) upon the
date Borrower's Class B Units in NEH are sold, assigned, redeemed, or otherwise
disposed of; or (iii) upon the date HEH sells all or substantially all of its
assets for cash and the members of NEH receive cash distributions of the sales
proceeds (the "Maturity Date").

          4.   As used herein, "Maturity Obligations" shall mean the entire
outstanding principal amount, together with all accrued but unpaid interest
thereon, and all other sums due and unpaid hereunder and under the Security
Agreement.


                                       1
<PAGE>   2
          5.   All payments due under this Note are payable at Lender's office
at 844 Moraga Drive, Los Angeles, California 90049 or at such other place as
Lender or other holder hereof shall notify Borrower in writing.

          6.   All payments received by Lender on this Note shall be applied by
Lender as follows: first, to the payment of delinquency or "late" charges, if
any; second, to accrued and unpaid interest; and third, to the reduction of the
Principal Amount.

          7.   Any portion of the Principal Amount, or interest unpaid at
maturity, or when the entire amount of this Note is otherwise due and payable,
as a result of acceleration, or otherwise, or after default, shall thereafter
accrue interest at fifteen percent (15%) per annum (the "Delinquency Rate").
The Delinquency Rate shall be effective both before and after any judgment as
may be rendered in a court of competent jurisdiction provided, however, that if
such Delinquency Rate is deemed to be interest in excess of the amount
permitted to be charged to Borrower under applicable law, Lender shall be
entitled to collect a Delinquency Rate only at the highest rate permitted by
law, and any interest actually collected by Lender in excess of such lawful
amount shall be deemed a payment in reduction of the principal amount then
outstanding under this Note and shall be so applied.

          8.   Borrower may prepay this Note in whole or in part without any
premium or penalty.

          9.   In the event of any conflict between the provisions of this Note
and those of the Security Agreement or any other document of any nature, the
provisions of this Note shall govern.

          10.  In the event Borrower fails to pay any installment of interest
or any principal on this Note for ten (10) days after the same shall become due
(a "Default") or upon the happening of any event of default as defined in the
Security Agreement, then, and in any such event, Lender may at its option
declare the entire unpaid Principal Amount, together with interest accrued
thereon, to be immediately due and payable and Lender may proceed to exercise
any rights or remedies that it may have under the Security Agreement, under
this Note, or under any other agreement relating to the Loan or such other
rights and remedies which Lender may have at law, equity, or otherwise. In the
event of such acceleration, Borrower may discharge his obligations to Lender by
paying the Maturity Obligations, with interest at the Delinquency Rate accruing
from the date such acceleration is declared.


                                       2

          11.  In the event this Note is turned over to an attorney at law for
collection after default, in addition to the Maturity Obligations, Lender shall
be entitled to collect all costs of collection, including but not limited to
reasonable attorneys' fees, incurred in connection with protection of, or
realization of, collateral or in connection with any of Lender's collection
efforts, whether or not suit on this Note or any foreclosure proceeding is
filed, and all such costs and expenses shall be payable on demand and shall
also be secured by the Security Agreement.

          12.  No failure on the part of Lender or other holder hereof to
exercise any right or remedy hereunder, whether before or after the happening
of a default shall constitute a waiver thereof, and no waiver of any past
default shall constitute waiver of any future default or of any other default.
No failure to accelerate the debt evidenced hereby by reason of default
hereunder, or acceptance of a past due installment, or indulgence granted from
time to time shall be construed to be a waiver of the right to insist upon
prompt payment thereafter or to impose late charges retroactively or
prospectively, or shall be deemed to be a novation of this Note or as a
reinstatement of the debt evidenced hereby or as a waiver of such right or
acceleration or any other right, or be construed so as to preclude the exercise
of any right which Lender may have, whether by the laws of the State of
California, by agreement or otherwise; and Borrower and each endorser or
guarantor hereby expressly waives the benefit of any statute or rule of law or
equity which would produce a result contrary to or in conflict with the
foregoing. This Note may not be changed orally, but only by an agreement in
writing signed by the party against whom such Agreement is sought to be
enforced.

          13.  Borrower, for him and his heirs, successors, and assigns, and
each endorser or guarantor of this Note, for its heirs, successors, and assigns,
hereby waives presentment, protest, demand, diligence, notice of dishonor and of
nonpayment, and waives and renounces all rights to the benefits of any statute
of limitations and any moratorium, appraisement, exemption, and homestead now
provided or which may hereafter be provided by any federal or state statute,
including but not limited to exemptions provided by or allowed under the
Bankruptcy Reform Act of 1978, both as to himself personally and as to all of
his property, whether real or personal, against the enforcement and collection
of the obligations evidenced by this Note and any and all extensions, renewals,
and modifications hereof.

          14.  Borrower represents and warrants to Lender that neither Borrower
nor anyone on his behalf has engaged in any conduct which would give rise to
any fee or commission of any broker, finder, or other person in connection with
this Loan. 



                                       3

Borrower hereby indemnifies and agrees to hold harmless Lender, its members,
directors, officers, employees, agents, and affiliates against any and all
claims, demands, causes of action, liabilities, losses, judgments, costs, and
expenses (including, without limitations, attorneys' fees) asserted with
respect to fees or commissions of brokers, finders, or others in connection
with any of the transactions referred to herein or contemplated hereby, and
shall pay in full any such claims on demand by Lender.

     15.  It is the intention of the parties to conform strictly to applicable
usury laws from time to time in force, and all agreements between Borrower and
Lender, whether now existing or hereafter arising and whether oral or written,
are hereby expressly limited so that in no contingency or event whatsoever,
whether by acceleration of maturity hereof or otherwise, shall the amount paid
or agreed to be paid to Lender or the holder hereof, or collected by Lender or
such holder, for the use, forbearance, or detention of the money to be lent
hereunder or otherwise, or for the payment or performance of any covenant or
obligation contained herein or in the Security Agreement, or in any other
document evidencing, securing, or pertaining to the indebtedness evidenced
hereby, exceed the maximum amount permissible under applicable usury laws. If
under any circumstances whatsoever fulfillment of any provision hereof or of
the Security Agreement, at the time performance of such provision shall be due,
shall involve transcending the limit of validity prescribed by law, then ipso
facto, the obligation to be fulfilled shall be reduced to the limit of such
validity; and if under any circumstances Lender or other holder hereof shall
ever receive an amount deemed interest, by applicable law, which would exceed
the highest lawful rate, such amount that would be excessive interest under
applicable usury laws shall be applied to the reduction of the principal amount
owing hereunder or to other indebtedness secured by the Security Agreement and
not to the payment of interest, or if such excessive interest exceeds the
unpaid principal amount and other indebtedness, the excess shall be deemed to
have been a payment made by mistake and shall be refunded to Borrower or to any
other person making such payment on Borrower's behalf. The terms and provisions
of this paragraph shall control and supersede every other provision of all
agreements between Lender and Borrower and any endorser or guarantor of this
Note.

     16.  This Note shall be governed by and construed under the laws of the
State of California. Borrower agrees that all actions or proceeding arising in
connection with this Note shall be tried and litigated only in the state and
federal courts located in Los Angeles County, California. Borrower hereby
submits to personal jurisdiction within the State of California for the
enforcement of Borrower's 



                                       4

obligations hereunder and under the Security Agreement, and waives any and all
personal rights under the law of any other state to object to jurisdiction
within the State of California for the purposes of litigation to enforce such
obligation of Borrower.

     IN WITNESS WHEREOF, Borrower, intending to be legally bound hereby, has
caused this Note to be duly executed the day and year first above written.

NOTICE TO BORROWER:  THIS DOCUMENT CONTAINS
                     PROVISIONS WHICH REQUIRE A
                     BALLOON PAYMENT AT MATURITY.



                                PROMISSORY NOTE



$72,000                                                          January 2, 1998


      1.    For value received, Michael Muldowney ("Borrower"), promises to pay
to the order of Nextera Enterprises Holdings, L.L.C., a Delaware limited
liability company, or its assigns ("Lender"), the sum of Seventy-Two Thousand
Dollars ($72,000), or such lesser sum as shall be advanced by Lender to
Borrower hereunder from time to time (the "Principal Amount"), with interest on
the unpaid balance of such amount from the date of the initial disbursement of
the loan (the "Loan") evidenced hereby, at the rate of interest specified
herein. This Note is secured by the security interest in Borrower's interest in
Nextera Enterprises Holdings, L.L.C., a Delaware limited liability company
("NEH"), granted in the Security Agreement of even date herewith entered into
between Lender and Borrower (the "Security Agreement"). Lender shall record the
amount and date of each advance hereunder on Schedule "A" attached hereto,
provided, however, the failure by Lender to make any such notation shall in no
way affect or impair Borrower's obligations to make all payments due hereunder.

      2.    The Principal Amount hereof shall bear interest at ten percent
(10%) per annum, compounded annually, but in no case shall the interest rate
exceed the maximum rate allowed by law.

      3.    A final payment of the Maturity Obligations (as hereinafter
defined) shall be due and payable upon the first to occur of the following: (i)
the date which is five (5) years from the date of this Note, or (ii) upon the
date Borrower's Class B Units in NEH are sold, assigned, redeemed, or otherwise
disposed of; or (iii) upon the date NEH sells all or substantially all of its
assets for cash and the members of NEH receive cash distributions of the sales
proceeds, (the "Maturity Date").

      4.    As used herein, "Maturity Obligations" shall mean the entire
outstanding principal amount, together with all accrued but unpaid interest
thereon, and all other sums due and unpaid hereunder and under the Security
Agreement.



                                       1
<PAGE>   2

      5.    All payments due under this Note are payable at Lender's office at
844 Moraga Drive, Los Angeles, California 90049 or at such other place as
Lender or other holder hereof shall notify Borrower in writing.

      6.    All payments received by Lender on this Note shall be applied by
Lender as follows: first, to the payment of delinquency or "late" charges, if
any; second, to accrued and unpaid interest; and third, to the reduction of the
Principal Amount.

      7.    Any portion of the Principal Amount, or interest unpaid at
maturity, or when the entire amount of this Note is otherwise due and payable,
as a result of acceleration, or otherwise, or after default, shall thereafter
accrue interest at fifteen percent (15%) per annum (the "Delinquency Rate").
The Delinquency Rate shall be effective both before and after any judgment as
may be rendered in a court of competent jurisdiction provided, however, that if
such Delinquency Rate is deemed to be interest in excess of the amount
permitted to be charged to Borrower under applicable law, Lender shall be
entitled to collect a Delinquency Rate only at the highest rate permitted by
law, and any interest actually collected by Lender in excess of such lawful
amount shall be deemed a payment in reduction of the principal amount then
outstanding under this Note and shall be so applied.

      8.    Borrower may prepay this Note in whole or in part without any
premium or penalty.

      9.    In the event of any conflict between the provisions of this Note
and those of the Security Agrement or any other document of any nature, the
provisions of this Note shall govern.

     10.    In the event Borrower fails to pay any installment of interest or
any principal on this Note for ten (10) days after the same shall become due (a
"Default") or upon the happening of any event of default as defined in the
Security Agreement, then, and in any such event, Lender may at its option
declare the entire unpaid Principal Amount, together with interest accrued
thereon, to be immediately due and payable and Lender may proceed to exercise
any rights or remedies that it may have under the Security Agreement, under
this Note, or under any other agreement relating to the Loan or such other
rights and remedies which Lender may have at law, equity, or otherwise. In the
event of such acceleration, Borrower may discharge his obligations to Lender by
paying the Maturity Obligations, with interest at the Delinquency Rate accruing
from the date such acceleration is declared.

      11.   In the event this Note is turned over to an attorney at law for
collection after default, in addition to the Maturity Obligations, Lender shall
be entitled to collect all costs of collection, including but not limited to
reasonable attorneys' fees, incurred in connection with protection of, or
realization of, collateral or in connection with any of Lender's collection
efforts, whether or not suit on this Note or any foreclosure proceeding is
filed, and all such costs and expenses shall be payable on demand and shall
also be secured by the Security Agreement.

      12.   No failure on the part of Lender or other holder hereof to exercise
any right or remedy hereunder, whether before or after the happening of a
default shall constitute a waiver thereof, and no waiver of any past default
shall constitute waiver of any future default or of any other default. No
failure to accelerate the debt evidenced hereby by reason of default
hereunder,or acceptance of a past due installment, or indulgence granted from
time to time shall be construed to be a waiver of the right to insist upon
prompt payment thereafter or to impose late charges retroactively or
prospectively, or shall be deemed to be a novation of this Note or as a
reinstatement of the debt evidenced hereby or as a waiver of such right or
acceleration or any other right, or be construed so as to preclude the exercise
of any right which Lender may have, whether by the laws of the State of
California, by agreement or otherwise; and Borrower and each endorser or
guarantor hereby expressly waives the benefit of any statute or rule of law or
equity which would produce a result contrary to or in conflict with the
foregoing. This Note may not be changed orally, but only by an agreement in
writing signed by the party against whom such agreement is sought to be
enforced.

      13.   Borrower, for him and his heirs, successors, and assigns, and each
endorser or guarantor of this Note, for its heirs, successors, and assigns,
hereby waives presentment, protest, demand, diligence, notice of dishonor and
of nonpayment, and waives and renounces all rights to the benefits of any
statute of limitations and any moratorium, appraisement, exemption, and
homestead now provided or which may hereafter be provided by any federal or
state statute, including but not limited to exemptions provided by or allowed
under the Bankruptcy Reform Act of 1978, both as to himself personally and as
to all of his property, whether real or personal, against the enforcement and
collection of the obligations evidenced by this Note and any and all
extensions, renewals, and modifications hereof.

      14.   Borrower represents and warrants to Lender that neither Borrower
nor anyone on his behalf has engaged in any conduct which would give rise to
any fee or commission of any broker, finder, or other person in connection with
this Loan.

Borrower hereby indemnifies and agrees to hold harmless Lender, its members,
directors, officers, employees, agents, and affiliates against any and all
claims, demands, causes of action, liabilities, losses, judgments, costs, and
expenses (including, without limitations, attorneys' fees) asserted with
respect to fees or commissions of brokers, finders, or others in connection
with any of the transactions referred to herein or contemplated hereby, and
shall pay in full any such claims on demand by Lender.

        15.     It is the intention of the parties to conform strictly to
applicable usury laws from time to time in force, and all agreements between
Borrower and Lender, whether now existing or hereafter arising and whether oral
or written, are hereby expressly limited so that in no contingency or event
whatsoever, whether by acceleration of maturity hereof or otherwise, shall the
amount paid or agreed to be paid to Lender or the holder hereof, or collected
by Lender or such holder, for the use, forbearance, or detention of the money
to be lent hereunder or otherwise, or for the payment or performance of any
covenant or obligation contained herein or in the Security Agreement, or in any
other document evidencing, securing, or pertaining to the indebtedness
evidenced hereby, exceed the maximum amount permissible under applicable usury
laws. If under any circumstances whatsoever fulfillment of any provision hereof
or of the Security Agreement, at the time performance of such provision shall
be due, shall involve transcending the limit of validity prescribed by law,
then ipso factor, the obligation to be fulfilled shall be reduced to the limit
of such validity; and if under any circumstances Lender or other holder hereof
shall ever receive an amount deemed interest, by applicable law, which would
exceed the highest lawful rate, such amount that would be excessive interest
under applicable usury laws shall be applied to the reduction of the principal
amount owing hereunder or to other indebtedness secured by the Security
Agreement and not to the payment of interest, or if such excessive interest
exceeds the unpaid principal amount and other indebtedness, the excess shall be
deemed to have been a payment made by mistake and shall be refunded to Borrower
or to any other person making such payment on Borrower's behalf. The terms and
provisions of this paragraph shall control and supersede every other provision
of all agreements between Lender and Borrower and any endorser or guarantor of
this Note.

        16.     This Note shall be governed by and construed under the laws of

NOTICE TO BORROWER:                  THIS DOCUMENT CONTAINS
                                     PROVISIONS WHICH REQUIRE A
                                     BALLOON PAYMENT AT MATURITY.


                                PROMISSORY NOTE

$62,000                                                         January 2, 1998


          1.   For value received, Debra Bergevine ("Borrower"), promises
to pay to the order of Nextera Enterprises Holdings, L.L.C., a Delaware limited
liability company, or its assign ("Lender"), the sum of Sixty-Two Thousand 
Dollars ($62,000), or such lesser sum as shall be advanced by Lender to Borrower
hereunder from time to time (the "Principal Amount"), with interest on the
unpaid balance of such amount from the date of the initial disbursement of the
loan (the "Loan") evidenced hereby, at the rate of interest specified herein.
This Note is secured by the security interest in Borrower's interest in Nextera
Enterprises Holdings, L.L.C., a Delaware limited liability company ("NEH"),
granted in the Security Agreement of even date herewith entered into between
Lender and Borrower (the "Security Agreement"). Lender shall record the amount
and date of each advance hereunder on Schedule "A" attached hereto, provided,
however, the failure by Lender to make any such notation shall in no way affect
or impair Borrower's obligations to make all payments due hereunder.

          2.   The Principal Amount hereof shall bear interest at ten percent
(10%) per annum, compounded annually, but in no case shall the interest rate
exceed the maximum rate allowed by law.

          3.   A final payment of the Maturity Obligations (as hereinafter
defined) shall be due and payable upon the first to occur of the following: (i)
the date which is five (5) years from the date of this Note, or (ii) upon the
date Borrower's Class B Units in NEH are sold, assigned, redeemed, or otherwise
disposed of; or (iii) upon the date HEH sells all or substantially all of its
assets for cash and the members of NEH receive cash distributions of the sales
proceeds, (the "Maturity Date").

          4.   As used herein, "Maturity Obligations" shall mean the entire
outstanding principal amount, together with all accrued but unpaid interest
thereon, and all other sums due and unpaid hereunder and under the Security
Agreement.



                                       1
<PAGE>   2
          5.   All payments due under this Note are payable at Lender's office
at 844 Moraga Drive, Los Angeles, California 90049 or at such other place as
Lender or other holder hereof shall notify Borrower in writing.

          6.   All payments received by Lender on this Note shall be applied by
Lender as follows: first, to the payment of delinquency or "late" charges, if
any; second, to accrued and unpaid interest; and third, to the reduction of the
Principal Amount.

          7.   Any portion of the Principal Amount, or interest unpaid at
maturity, or when the entire amount of this Note is otherwise due and payable,
as a result of acceleration, or otherwise, or after default, shall thereafter
accrue interest at fifteen percent (15%) per annum (the "Delinquency Rate").
The Delinquency Rate shall be effective both before and after any judgment as
may be rendered in a court of competent jurisdiction provided, however, that if
such Delinquency Rate is deemed to be interest in excess of the amount
permitted to be charged to Borrower under applicable law, Lender shall be
entitled to collect a Delinquency Rate only at the highest rate permitted by
law, and any interest actually collected by Lender in excess of such lawful
amount shall be deemed a payment in reduction of the principal amount then
outstanding under this Note and shall be so applied.

          8.   Borrower may prepay this Note in whole or in part without any
premium or penalty.

          9.   In the event of any conflict between the provisions of this Note
and those of the Security Agreement or any other document of any nature, the
provisions of this Note shall govern.

          10.  In the event Borrower fails to pay any installment of interest
or any principal on this Note for ten (10) days after the same shall become due
(a "Default") or upon the happening of any event of default as defined in the
Security Agreement, then, and in any such event, Lender may at its option
declare the entire unpaid Principal Amount, together with interest accrued
thereon, to be immediately due and payable and Lender may proceed to exercise
any rights or remedies that it may have under the Security Agreement, under
this Note, or under any other agreement relating to the Loan or such other
rights and remedies which Lender may have at law, equity, or otherwise. In the
event of such acceleration, Borrower may discharge his obligations to Lender by
paying the Maturity Obligations, with interest at the Delinquency Rate accruing
from the date such acceleration is declared.

     11.  In the event this Note is turned over to an attorney at law for
collection after default, in addition to the Maturity Obligations, Lender shall
be entitled to collect all costs of collection, including but not limited to
reasonable attorneys' fees, incurred in connection with protection of, or
realization of, collateral or in connection with any of Lender's collection
efforts, whether or not suit on this Note or any foreclosure proceeding is
filed, and all such costs and expenses shall be payable on demand and shall
also be secured by the Security Agreement.

     12.  No failure on the part of Lender or other holder hereof to exercise
any right or remedy hereunder, whether before or after the happening of a
default shall constitute a waiver thereof, and no waiver of any past default
shall constitute waiver of any future default or of any other default. No
failure to accelerate the debt evidenced hereby by reason of default hereunder,
or acceptance of a past due installment, or indulgence granted from time to time
shall be construed to be a waiver of the right to insist upon prompt payment
thereafter or to impose late charges retroactively or prospectively, or shall be
deemed to be a novation of this Note or as a reinstatement of the debt evidenced
hereby or as a waiver of such right or acceleration or any other right, or be
construed so as to preclude the exercise of any right which Lender may have,
whether by the laws of the State of California, by agreement or otherwise; and
Borrower and each endorser or guarantor hereby expressly waives the benefit of
any statute or rule of law or equity which would produce a result contrary to or
in conflict with the foregoing. This Note may not be changed orally, but only by
an agreement in writing signed by the party against whom such agreement is
sought to be enforced.

     13.  Borrower, for him and his heirs, successors, and assigns, and
each endorser or guarantor of this Note, for its heirs, successors, and
assigns, hereby waives presentment, protest, demand, diligence, notice of
dishonor and of nonpayment, and waives and renounces all rights to the benefits
of any statute of limitations and any moratorium, appraisement, exemption, and
homestead now provided or which may hereafter be provided by any federal or
state statute, including but not limited to exemptions provided by or allowed
under the Bankruptcy Reform Act of 1978, both as to himself personally and as
to all of his property, whether real or personal, against the enforcement and
collection of the obligations evidenced by this Note and any and all
extensions, renewals, and modifications hereof.

     14.  Borrower represents and warrants to Lender that neither Borrower
nor anyone on his behalf has engaged in any conduct which would give rise to
any fee or commission of any

broker, finder, or any other person in connection with this Loan. Borrower
hereby indemnifies and agrees to hold harmless Lender, its members, directors,
officers, employees, agents, and affiliates against any and all claims, demands,
causes of action, liabilities, losses, judgments, costs, and expenses
(including, without limitations, attorneys' fees) asserted with respect to fees
or commissions of brokers, finders, or others in connection with any of the
transactions referred to herein or contemplated hereby, and shall pay in full
any such claims on demand by Lender.

     15.  It is the intention of the parties to conform strictly to applicable
usury laws from time to time in force, and all agreements between Borrower and
Lender, whether now existing or hereafter arising and whether oral or written,
are hereby expressly limited so that in no contingency or event whatsoever,
whether by acceleration of maturity hereof or otherwise, shall the amount paid
or agreed to be paid to Lender or the holder hereof, or collected by Lender or
such holder, for the use, forbearance, or detention of the money to be lent
hereunder or otherwise, or for the payment or performance of any covenant or
obligation contained herein or in the Security Agreement, or in any other
document evidencing, securing, or pertaining to the indebtedness evidenced
hereby, exceed the maximum amount permissible under applicable usury laws. If
under any circumstances whatsoever fulfillment of any provision hereof or of
the Security Agreement, at the time performance of such provision shall be due,
shall involve transcending the limit of validity prescribed by law, then ipso
facto, the obligation to be fulfilled shall be reduced to the limit of such
validity; and if under any circumstances Lender or other holder hereof shall
ever receive an amount deemed interest, by applicable law, which would exceed
the highest lawful rate, such amount that would be excessive interest under
applicable usury laws shall be applied to the reduction of the principal amount
owing hereunder or to other indebtedness secured by the Security Agreement and
not to the payment of interest, or if such excessive interest exceeds the
unpaid principal amount and other indebtedness, the excess shall be deemed to
have been a payment made by mistake and shall be refunded to Borrower or to any
other person making such payment on Borrower's behalf. The terms and provisions
of this paragraph shall control and supersede every other provision of all
agreements between Lender and Borrower and any endorser or guarantor of this
Note.

     16.  This Note shall be governed by and construed under the laws of the
State of California. Borrower agrees that all actions or proceeding arising in
connection with this Note shall be tried and litigated only in the state and
federal courts located in Los Angeles County, California.

Borrower hereby submits to personal jurisdiction within the State of California
for the enforcement of Borrower's obligations hereunder and under the Security
Agreement, and waives any and all personal rights under the law of any other
state to object to jurisdiction within the State of California for the purposes
of litigation to enforce such obligation of Borrower.

      IN WITNESS WHEREOF, Borrower, intending to be legally bound hereby, has
caused this Note to be duly executed the day and year first above written.
